1.   General

     The consolidated condensed financial statements as of September 30, 1995
     and for the three and nine months ended September 30, 1995 and 1994 are
     unaudited.  Certain reclassifications of prior period information have
     been made to conform to current year presentation.  In April 1994
     Healthdyne, Inc. (the "Company") sold its 68% ownership in Home
     Nutritional Services, Inc., a New Jersey corporation ("HNS"), in May 1995
     the Company distributed to its shareholders, in the form of a tax-free
     dividend, its 81% ownership in Healthdyne Technologies, Inc., a Georgia
     corporation ("Healthdyne Technologies"), and in October 1995 the Company's
     Board of Directors approved the spin-off of its wholly-owned subsidiary,
     Healthdyne Information Enterprises, Inc. ("HIE"), in a taxable
     distribution.  The accounts of HNS, Healthdyne Technologies and HIE prior
     to sale or distribution have been segregated and reflected as discontinued
     operations in the consolidated condensed financial statements as of
     September 30, 1995 and December 31, 1994 and for the three and nine months
     ended September 30, 1995 and 1994 (See Notes 3 and 4).  The only remaining
     business of the Company is the business of its Healthdyne Maternity
     Management division (HMM).  In the opinion of management, all adjustments,
     consisting of normal recurring accruals, necessary for the fair
     presentation of the consolidated financial position and results of
     operations and cash flows for the periods presented have been included.
     The results for the three and nine months ended September 30, 1995 are not
     necessarily indicative of the results for the full year ending December
     31, 1995.

     These consolidated condensed financial statements should be read in
     conjunction with the consolidated financial statements and related notes
     included in the Annual Report on Form 10-K of the Company for the year
     ended December 31, 1994.

2.   Earnings Per Share of Common Stock

     Primary earnings per common share and common share equivalent are based on
     the weighted average number of shares outstanding and common share
     equivalents derived from dilutive stock options and warrants.  Fully
     diluted earnings per share are calculated taking into consideration the
     effect of convertible subordinated debentures.  Fully diluted earnings per
     share are not significantly different from primary earnings per share.

3.   Discontinued Operations

     During the first quarter of 1994, the Company decided to divest its 68%
     ownership interest in HNS.  The sale was consummated in April 1994 and
     resulted in net proceeds to the Company of approximately $61,000 and a
     gain, net of income taxes, of $17,330.  Accordingly, the operations of HNS
     for the three and nine months ended September 30, 1994 have been presented
     as discontinued operations.

     On May 22, 1995, the Company distributed its 81% ownership in its
     subsidiary, Healthdyne Technologies, to the Company's shareholders of
     record on May 5, 1995 in a tax-free distribution (the "Technologies
     Spin-off").  The Company's consolidated condensed financial statements
     reflect the results of operations of Healthdyne Technologies included in
     the nine month period ended September 30, 1995 and all previously reported
     periods as discontinued operations.  The Technologies Spin-off resulted in
     a reduction of additional paid-in capital of $25,480, representing 81% of 
     the book value of assets of Healthdyne Technologies.

4.   Subsequent Events

     On October 20, 1995, the Company's Board of Directors approved the
     distribution of its wholly-owned subsidiary, HIE, to shareholders of record
     on October 30, 1995,  in a taxable distribution (the "HIE Spin-off").  The
     Company's consolidated condensed financial statements reflect the results
     of operations of HIE included in the current periods and all previously
     reported periods as discontinued operations.  The HIE Spin-off will result
     in a reduction of additional paid-in capital in the amount of the net book
     value of the assets of HIE on the distribution date, November 6, 1995.  As
     of September 30, 1995 the net book value of the assets of HIE was $17,809.

     On October 2, 1995, the Company and Tokos Medical Corporation (Delaware)
     ("Tokos") entered into an Agreement and Plan of Merger providing for a
     merger (the "Merger") of Healthdyne and Tokos. The Merger is expected to 
     be a tax-free transaction with each Healthdyne and each Tokos share to be 
     exchanged for one share of a new company, which has yet to be named.  The 
     transaction is anticipated to be completed in early 1996, subject to 
     certain conditions and shareholder approval from both companies.

                ITEM 2. - MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                             (AMOUNTS IN THOUSANDS)

General

     On April 6, 1994 the Company sold its 68% ownership interest in Home
Nutritional Services, Inc. ("HNS"); on May 22, 1995 the Company distributed
to its shareholders the 10 million shares of common stock (approximately 81% of
the outstanding shares) of Healthdyne Technologies, Inc. ("Healthdyne
Technologies") owned by the Company in a tax-free distribution (the
"Technologies Spin-off"); and in October 1995 the Company's Board of Directors
approved the spin-off of its wholly-owned subsidiary, Healthdyne Information
Enterprises, Inc. ("HIE"), in a taxable distribution (the "HIE Spin-off").  The
accounts of HNS, Healthdyne Technologies and HIE prior to sale or distribution
have been reflected herein as discontinued operations.

     Following the distribution of the Company's interest in HIE to
shareholders on November 6, 1995, the sole remaining business of the Company is
Healthdyne Maternity Management ("HMM"), a wholly-owned division which provides
home obstetrical care and related risk management services.  On October 2,
1995, the Company and Tokos Medical Corporation (Delaware) ("Tokos") entered
into an Agreement and Plan of Merger providing for a merger (the "Merger")
which will create a new company, which has yet to be named, consisting of Tokos
and Healthdyne and will be a nationwide provider of pregnancy management 
services and high-risk home obstetrical care.

     The Company's present operations and future prospects may be influenced by
several factors, including developments in the healthcare industry, third-party
reimbursement policies and practices, and changes in regulatory requirements or
the manner in which such requirements are enforced with respect to approval and
use of medical devices.  As a result of the increasing cost of health care in
the United States and overall efforts to reduce or control government and
corporate spending, government and third-party payors are becoming increasingly
focused on promoting cost-effective healthcare services, and payors, in
particular, have become more involved in decisions regarding diagnosis and
treatment to ensure that care is delivered in a cost-effective manner.

     Substantially all of the Company's current revenues are derived directly
from third-party payors for services rendered to patients by the Company.  The
levels of profitability of all healthcare companies, including the Company,
could be adversely affected by the financial condition of certain governmental
and private payors and by their continuing efforts to reduce healthcare costs
by lowering reimbursement rates, increasing medical reviews of invoices for
services and negotiating for reduced contract rates.  The Company has responded
to these developments by attempting to emphasize cost-effective therapies and
procedures, pre-qualifying insurance coverage prior to the delivery of services
and educating third-party payors on the benefits of the Company's home
therapies.  Although reductions in the reimbursement rates that the Company
receives for services rendered could have an adverse impact on the Company, the
Company is hopeful that the overall cost-effective nature of treatment in the
home (as compared to hospitalization), coupled with the potential benefits to
be derived from prenatal care, will be recognized and encouraged by any new
healthcare initiatives.

     The Company's business also may be affected by changes in government
regulation to which the Company's products and services are subject or changes
in the manner in which such regulations are enforced or medical devices are
approved.  In September 1995 the United States Food and Drug Administration
("FDA") approved the PreMarket Approval Application filed for the Company's
System 37(R) Uterine Activity Monitor utilized by HMM.  The lack of FDA approval
historically has adversely affected third-party reimbursement. The FDA approval
of System 37(R) is expected to result in a higher level of acceptance of home
uterine activity monitoring for reimbursement by some insurance carriers and
state medicaid programs.

                                      9
<PAGE>   10

     The trend within the healthcare industry to deliver quality healthcare
services in a more cost-effective manner has had, and is expected to continue
to have, an impact on the Company.  Driven by employers and third-party payors,
as well as by legislation and regulation, prices for services provided to
patients, in general, are being reduced, cost- effective preventative health
care is being stressed and vertically integrated networks of care providers
(some of whom are accepting the insurance risk of providing care through
capitation contracts with third-party payors) are being established.  The
Company anticipates that this trend will continue and is attempting to focus
its efforts on services, some of which are offered in conjunction with
third-party payors, which it believes can benefit from this new environment.
There can be no assurance, however, that either additional changes or presently
unforeseen consequences from this trend may not develop.

     The following discussion of the Company's financial condition and results
of operations should be read in conjunction with the Company's consolidated
financial statements and related notes presented in the Company's Annual Report
on Form 10-K for the year ended December 31, 1994 as filed with the Securities
and Exchange Commission.

Operating Results

         Consolidated revenues from continuing operations, which are derived
solely from the business of HMM, increased 3% to $17,732 and 6% to $51,935 in
the three and nine months ended September 30, 1995, respectively, as compared
to the same periods in 1994.  The increases are due primarily to higher average
patient census.

     The Company's gross profit margin improved from 58% to 60% in the three
months ended September 30, 1995 as compared to the same period in 1994. and
remained constant at 59% in the nine month periods ended September 30, 1995 and
1994.

     The Company's selling and administrative expenses remained relatively
constant as a percentage of revenues, at 54% and 55% in the three and nine
months, ended September 30, 1995 and 1994, respectively as compared to 54% and
56% in the same periods in the prior year.

     The Company provides for doubtful accounts to cover that portion of billed
revenue that it estimates to be uncollectible.  This provision is adjusted
periodically based upon the Company's evaluation of historical collection
experience, industry reimbursement trends and other relevant factors.  Due to
significantly improved collection experience at HMM beginning in late 1994 and
continuing to date, the provision was decreased from 8% and 9% of revenues in
the three and nine months ended September 30, 1994, respectively, to 6% of
revenues in 1995.

     Minority interest in net earnings of partnerships is the result of
strategic alliances established by the Company through HMM.  Changes in
regulatory requirements have resulted in the acquisition or dissolution of
certain partnerships, and more are expected in the future.

     For the three and nine months ended September 30, 1995, the effective
income tax benefit was greater than the statutory rate because of the
utilization of the Company's operating tax losses and receipt of non-taxable
interest income.

Liquidity and Capital Resources

     As of September 30, 1995, the Company had cash and short-term investments
of $29,950.  Working capital as of that date was $52,032 and the current ratio
was 4.2 to 1.

     Consolidated cash flow provided by continuing operating activities was
$4,466 and $3,215 in the nine months ended September 30, 1995 and 1994,
respectively.  Cash used in continuing investing activities increased to $6,613
from $2,065 in the nine months ended September 30, 1995 and 1994, respectively.
This increase was due primarily to increased

                                      10
<PAGE>   11

capital expenditures at HMM, additional equity investments in affiliates and
the acquisition of the minority interests of certain partnerships.

     It is not expected that the Technologies Spin-off will have a material
effect on the Company's liquidity or available cash flow.  Since the initial
public offering of Healthdyne Technologies in 1993, the Company has neither
provided significant funding to, nor obtained significant funding from,
Healthdyne Technologies.  Since such date, including the nine months ended
September 30, 1995, Healthdyne Technologies has purchased certain services from
the Company at a price which approximates the cost of such services and HMM has
purchased certain equipment from Healthdyne Technologies at 33% above
manufacturing cost.  These arrangements will continue for a period of time
after the Technologies Spin-off although the services required to be provided
to Healthdyne Technologies and the payments thereunder are expected to be
reduced.  Healthdyne Technologies and the Company were also parties to a Tax
Sharing Agreement pursuant to which Healthdyne Technologies paid the Company
$2,869 in the year 1994 and $1,423 in 1995, for the utilization of the
Company's tax operating losses.  After the Technologies Spin-off, the earnings
of Healthdyne Technologies will not be included in the Company's consolidated
income tax return and, thus, Healthdyne Technologies cannot utilize the
Company's tax operating losses and no further payments will be received by the
Company under this agreement.

     It is not expected that the HIE Spin-off will have a material effect on
the Company's liquidity or available cash flow.  Upon completion of the HIE
Spin-off, Healthdyne has no further obligation to provide funding for HIE.  HIE
has, since its inception, purchased certain services from the Company at a
price which approximates cost of such services.  These arrangements will
continue for a period of time after the HIE Spin-off.

     As of September 30, 1995, the Company had no material commitments for
capital expenditures.  However, the Company and Tokos will incur substantial
costs in connection with the Merger, including restructuring, investment
banking fees, legal and other charges.  It is anticipated that existing funds 
and expected cash flows from operating and investing activities will enable the
Company to make investments in its remaining business and to meet its 
scheduled obligations.

RECENT ACCOUNTING PRONOUNCEMENTS

     In 1994, the Financial Accounting Standards Board issued Statement of 
Financial Accounting Standards No. 119 ("SFAS 119"), "Disclosure About 
Derivative Financial Instruments and Fair Value of Financial Instruments".  
Had SFAS 119 been implemented by the Company as of September 30, 1995, there 
would have been no material effect on the consolidated condensed financial 
statements.

ITEM 5.   Other Information

     On October 20, 1995 the Board of Directors of the Company approved a plan 
to distribute the Company's 100% owned interest in HIE, its wholly-owned
subsidiary to the shareholders of the Company in a taxable distribution (the
"HIE Spin-Off").  No holder of shares of Company Common Stock were required to
pay any cash or other consideration for the shares of HIE Common Stock
distributed or to surrender or exchange shares of the Company's Common Stock in
order to receive HIE Common Stock.  The Board of Directors of HIE previously
approved an Adjustment Stock Option Plan and other arrangements related to the
HIE Spin-Off.  The Company's Board of Directors established October 30, 1995 as
the record date and November 6, 1995 as the date for the HIE Spin-Off.

     The HIE Spin-Off was effected on November 6, 1995, by mailing certificates
of HIE Common Stock to the holders of record of Company Common Stock on October
30, 1995.  One share of HIE Common Stock was distributed for each share of
Company Common Stock held of which 16,114,851 were outstanding on the record
date.  Also included in the mailing with the HIE Common Stock certificates was
a supplement to HIE's Prospectus dated October 31, 1995 announcing, that on
November 1, 1995, a lawsuit was filed against the Company and HIE by Healthcare
Communications, Inc. ("HCI"), a 57% owned subsidiary of HIE, and certain
minority shareholders of HCI, including Jerry D. Scott, President of HCI.  The
lawsuit was filed in the State District Court in Dallas, Texas seeking to
enjoin the HIE Spin-Off as well as the Company's transfer to HIE of certain
rights to purchase the remaining stock of HCI.  In addition the lawsuit seeks
to declare the transfer of HCI stock from Healthdyne to HIE as void, rescission
of certain agreements between the parties, damages in an unspecified amount,
and certain other equitable relief.  Pursuant to a motion filed by the Company
and HIE on November 3, 1995, the action was removed to the United States
District Court for the Northern District of Texas, Dallas Division.  The
Company and HIE believe the allegations made in the lawsuit are without merit
and intend to vigorously defend their respective positions.

     Following the HIE Spin-Off, the Company does not own any shares of HIE
Common Stock and all 16,114,851 outstanding shares are available for trading on
the National Association of Securities Dealers over the counter Bulletin Board.

     On October 20, 1995, the Company and HIE entered into a Distribution
Agreement, which set forth their rights and obligations in connection with the
HIE Spin-Off and also executed related Tax Indemnity and Tax Disaffiliation
Agreements, a Corporate Services Agreement, and a License Agreement.  These
agreements were attached as exhibits to HIE's Registration Statement on Form
S-1 (Reg. No. 33-96478) and are incorporated herein by reference.

         WHEREAS, the Boards of Directors of TM and HD have determined that it
is in the best interests of their respective companies and stockholders to
combine their respective businesses in a "merger of equals" transaction to be
effected as set forth in this Agreement;

         WHEREAS, for federal income tax purposes, it is intended that the
Merger shall qualify as a reorganization within the meaning of Section 368(a)

         NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, the

                                   ARTICLE IV

                              CONVERSION OF SHARES

         4.1     Exchange Ratio.  At the Effective Time, by virtue of the
Merger and without any action on the part of the holder thereof:

                 (a)      Each share of Common Stock, par value $.001 per
share, of TM ("TM Common Stock"), issued and outstanding immediately prior to
the Effective Time, together with any associated TM Rights as defined in
Section 5.2 below, shall be cancelled and extinguished and converted into the
right to receive one share of Common Stock, par value $.01 per share, of Newco
("Newco Common Stock").  All such shares of TM Common Stock shall no longer be
deemed outstanding, shall be cancelled and retired and shall cease to exist.
Each holder of a certificate representing any such TM Common Stock shall
thereafter cease to have any rights with respect to such TM Common Stock, other
than the right to receive a number of shares of Newco Common Stock equal to the
number of shares of TM Common Stock previously evidenced by such certificate
upon the surrender of such certificate in accordance with, and subject to
adjustment as provided in, Section 4.1(c).  Each share of TM Common Stock then
held in the treasury of TM ("TM Treasury Shares") and each share ("TM Preferred
Shares") of Preferred Stock, par value $.001 per share ("TM Preferred Stock"),
shall be cancelled and retired, and no payment shall be made with respect
thereto.

                 (b)      Each share of Common Stock, par value $.01 per share,
of HD ("HD Common Stock" and collectively with the TM Common Stock, the
"Shares") issued and outstanding immediately prior to the Effective Time,
together with any associated HD Rights as defined in Section 6.2 below, shall
be cancelled and extinguished and converted into the right to receive one share
of Newco Common Stock.  All such shares of HD Common Stock (by virtue of the
Merger and without any action on the part of the holders thereof) shall no
longer be deemed outstanding, shall be cancelled and retired and shall cease to
exist.  Each holder of a certificate representing any such shares of HD Common
Stock shall thereafter cease to have any rights with respect to such shares of
HD Common Stock, other than the right to receive a number of shares of Newco
Common Stock equal to the number of shares of HD Common Stock previously
evidenced by such certificate upon the surrender of such certificate in
accordance with, and subject to adjustment as provided in, Section 4.1(c).
Each share of HD Common Stock then held in the treasury of HD ("HD Treasury
Shares") and each share ("HD Preferred Shares") of Preferred Stock, par value
$.01 per share ("HD Preferred Stock") shall be cancelled and retired, and no
payment shall be made with respect thereto.

                 (c)      At the Effective Time, all shares of TM Common Stock
(the "TM Shares") and all shares of HD Common Stock (the "HD Shares") shall no
longer be outstanding and shall automatically be cancelled and retired and
shall cease to exist, and each certificate previously representing any such
Shares shall thereafter represent shares of Newco Common Stock (the "Newco
Shares") into which such Shares have been converted.  Certificates representing
Shares shall be exchanged for certificates representing whole Newco Shares
issued in consideration therefor upon the surrender of such certificate in
accordance with the provisions hereof.  If prior to the Effective Time TM or HD
should split or combine the TM Shares or HD Shares, as applicable, or pay a
stock dividend or other stock distribution in TM Shares or HD Shares (except
for the "HIE Spinoff" (as defined in Schedule 7.1)), as applicable, then the
number of Newco Shares to be issued in exchange for each share of TM Common
Stock or HD Common Stock, as the case may be, will be appropriately adjusted to
reflect such split, combination, dividend or other distribution.

                 (d)      Newco may adopt a Stockholders Rights Plan ("Newco
Rights Plan") prior to the Effective Time.  In that event, all references in
this Agreement to Newco Shares shall be deemed to include the associated
preferred stock purchase rights under the Newco Rights Plan except where the
context otherwise clearly requires.

         4.2     Exchange of Shares.

                 (a)      Prior to the Effective Time, Newco shall select and
enter into an agreement (in form and substance reasonably satisfactory to HD
and TM) with a bank or trust company to act as Exchange Agent hereunder (the
"Exchange Agent").  No later than the Effective Time, Newco shall make
available, and each holder of Shares will be entitled to receive, upon
surrender to the Exchange Agent of one or more certificates representing such
Shares for cancellation, certificates representing the number of Newco Shares
into which such Shares are converted in the Merger.  The Newco Shares into
which the Shares shall be converted in the Merger shall be deemed to have been
issued at the Effective Time.

                 (b)      As soon as reasonably practicable after the Effective
Time, the Exchange Agent shall mail to each holder of record of a certificate
or certificates which immediately prior to the Effective Time represented
outstanding Shares (the "Certificates") whose Shares were converted into Newco
Shares pursuant to Section 4.1, (i) a letter of transmittal (which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Exchange
Agent and shall be in such form and have such other provisions as TM and HD may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for certificates representing Newco Shares.  Upon
surrender of a Certificate for cancellation to the Exchange Agent together with
such letter of transmittal, duly executed, the holder of such Certificate shall
be entitled to receive in exchange therefor a certificate representing that
number of whole Newco Shares which such holder has the right to receive in
respect of the Certificates surrendered pursuant to the provisions of this
Article IV.

                 (c)      In the event that any stock certificate representing
Shares shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the person claiming such certificate to be lost,
stolen or destroyed, Newco will issue or cause to be issued in exchange for
such lost, stolen or destroyed certificate the number of Newco Shares into
which such Shares are converted in the Merger in accordance with this Article
IV.  When authorizing such issuance in exchange therefor, the Board of
Directors of Newco may, in its discretion and as a condition precedent to the
issuance thereof, require the owner of such lost, stolen or destroyed
certificate to give Newco a bond in such sum as it may direct as indemnity, or
such other form of indemnity, as it shall direct, against any claim that may be
made against Newco with respect to the certificate alleged to have been lost,
stolen or destroyed.

         4.3     Dividends; Transfer Taxes.  No dividends that are declared on
Newco Shares will be paid to persons entitled to receive certificates
representing Newco Shares until such persons surrender their certificates
representing Shares.  Upon such surrender, there shall be paid to the person in
whose name the certificates representing such Newco Shares shall be issued, any
dividends which shall have become payable with respect to such Newco Shares
between the Effective Time and the time of such surrender.  In no event shall
the person entitled to receive such dividends be entitled to receive interest
on such dividends.  If any certificates for any Newco Shares are to be issued
in a name other than that in which the certificate representing Shares
surrendered in exchange therefor is registered, it shall be a condition of such
exchange that the person requesting such exchange shall pay to the Exchange
Agent any transfer or other taxes required by reason of the issuance of
certificates for such Newco Shares in a name other than that of the registered
holder of the certificate surrendered, or shall establish to the satisfaction
of the Exchange Agent that such tax has been paid or is not applicable.
Notwithstanding the foregoing, neither the Exchange Agent nor any party hereto
shall be liable to a holder of Shares for any Newco Shares or dividends thereon
or, in accordance with Section 4.4 hereof, the cash payment for fractional
interests, delivered to a public official pursuant to applicable escheat laws.

         4.4     No Fractional Securities.  No certificates or scrip
representing fractional Newco Shares shall be issued upon the surrender for
exchange of certificates representing Shares pursuant to this Article IV and no
dividend, stock split-up or other change in the capital structure of Newco
shall relate to any fractional security, and such fractional interests shall
not entitle the owner thereof to vote or to any rights of a security holder.
In lieu of any such fractional securities, each holder of Shares who would
otherwise have been entitled to a fraction of a Newco Share upon surrender of
stock certificates for exchange pursuant to this Article IV will be paid cash
upon such surrender in an amount equal to the product of such fraction
multiplied by the Average Price of a Newco Share.  As used herein, the "Average
Price" of a Newco Share shall mean the average of the closing prices of a share
of Newco Common Stock as reported by The Wall Street Journal over the five
trading days commencing on the third trading day following the Closing.

         4.5     Closing of Transfer Books.  At the Effective Time, the stock
transfer books of HD and TM shall be closed and no transfer of Shares shall
thereafter be made.  If, after the Effective Time, certificates representing
Shares are presented to the Surviving Corporation, they shall be cancelled and
exchanged for certificates representing Newco Shares in accordance with the
terms hereof.  At and after the Effective Time, the holders of





                                      -6-
<PAGE>   7

Shares to be exchanged for Newco Shares pursuant to this Agreement shall cease
to have any rights as stockholders of HD or TM, as applicable, except for the
right to surrender such stock certificates in exchange for Newco Shares as
provided hereunder.

         4.6     Closing.  The closing of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Troutman Sanders
LLP, 600 Peachtree Street, N.E., 5200 NationsBank Plaza, Atlanta, Georgia
30308-2216 at 9:00 a.m., local time, on the day after the later of (a) the date
on which the later to occur of HD's and TM's stockholders' meetings referred to
in Section 8.4 hereof shall have occurred or (b) the day on which all of the
conditions set forth in Article IX hereof are satisfied or waived, or at such
other date, time and place as TM and HD shall agree.

         4.7     Supplementary Action.  If at any time after the Effective
Time, any further assignments or assurances in law or any other things are
necessary or desirable to vest or to perfect or confirm of record in the
Surviving Corporation the title to any property or rights of HD or TM, or
otherwise to carry out the provisions of this Agreement, the officers and
directors of the Surviving Corporation are hereby authorized and empowered on
behalf of HD and TM, in the name of and on behalf of HD and TM, to execute and
deliver any and all things necessary or proper to vest or to perfect or confirm
title to such property or rights in the Surviving Corporation, and otherwise to
carry out the purposes and provisions of this Agreement.


                                   ARTICLE V

         As used in this Agreement, (i) the word "subsidiary" when used with
respect to any party means any corporation or other organization, whether
incorporated or unincorporated, of which such party or any other subsidiary of

stockholders and Healthdyne Information Enterprises, Inc., a Georgia
corporation, and its direct and indirect subsidiaries (collectively, "HIE")
from and after the date of the spinoff of HIE's common stock to HD shareholders
(the "HIE Spinoff")) and (ii) the term "Material Adverse Effect" means, with
respect to HD and TM, as the case may be, a material adverse effect on the
business, assets, revenues, expenses or financial condition of such party and
its subsidiaries (excluding, for purposes of HD, HTI and HIE) taken as a whole
or in the ability of such party to perform its obligations hereunder.

         Each of the following representations and warranties is qualified by
the disclosure letter (the "TM Disclosure Letter") delivered to HD immediately
prior to the execution hereof, whether or not reference is made to the TM
Disclosure Letter in such representation or warranty.  Except as set forth in
the TM Disclosure Letter or in the "TM SEC Reports" (as hereinafter defined)
filed prior to the execution of this Agreement, TM represents and warrants to
HD as follows:

         5.1     Organization.  TM is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware and has
the corporate power to carry on its business as it is now being conducted or
presently proposed to be conducted.  TM is duly qualified as a foreign
corporation to do business, and is in good standing (to the extent the concept
of good standing exists), in each jurisdiction where the character of its
properties owned or held under lease or the nature of its activities makes such
qualification necessary, except where the failure to be so qualified will not
have a Material Adverse Effect.  Each subsidiary of TM which is incorporated is
a corporation duly organized, validly existing and in good standing (to the
extent the concept of good standing exists) under the laws of its jurisdiction
of incorporation or organization, has the corporate power to carry on its
business as it is now being conducted and is duly qualified to do business, and
is in good standing (to the extent the concept of good standing exists), in
each jurisdiction where the character of its properties owned or held under
lease or the nature of its activities makes such qualification necessary,
except where the failure to be so duly organized, validly existing and in good
standing, to have such corporate power or to be so qualified will not have a
Material Adverse Effect.  TM has delivered to HD or its counsel complete and
correct copies of its, and its subsidiaries, Certificate of Incorporation and
Bylaws or other organizational documents.

         5.2     Capitalization.  The authorized capital stock of TM consists
of 60,000,000 shares of Common Stock, par value $.001 per share, and 2,000,000
shares of TM Preferred Stock.  As of the date hereof, 17,478,851 TM Shares were
issued and outstanding, options to acquire 2,150,960 TM Shares ("TM Stock
Options") were





                                      -8-
<PAGE>   9

outstanding under all stock option plans of TM ("TM Stock Option Plans") and no
warrants to acquire TM Shares were outstanding, and no shares of TM Preferred
Stock were issued and outstanding.  All of the issued and outstanding TM Shares
are validly issued, fully paid and nonassessable and free of preemptive rights
or similar rights created by statute, the Certificate of Incorporation or
Bylaws of TM or any agreement to which TM or any of its subsidiaries is a party
or by which it is bound.  Since December 31, 1994, TM has not issued any shares
of its capital stock, except upon the exercise of stock options previously
granted under TM Stock Option Plans and pursuant to TM's Employee Stock
Purchase Plan.  Except as set forth above and pursuant to TM's employee benefit
plans and as otherwise provided in this Agreement and that certain Stockholder
Rights Plan, dated March 19, 1993, between TM and U.S. Stock Transfer
Corporation, as rights agent ("TM Rights Agreement"), pursuant to which TM
Rights Agreement certain rights ("TM Rights") to purchase TM Shares were
issued, there are not as of the date of this Agreement any shares of capital
stock of TM issued or outstanding or any options, warrants, subscriptions,
calls, rights, convertible securities or other agreements or commitments
obligating TM to issue, transfer or sell any shares of its capital stock.  As
of the date hereof, no bonds, debentures, notes or other indebtedness having
the right to vote (or convertible into or exercisable for securities having the
right to vote) on any matters on which stockholders may vote ("Voting Debt") of
TM were issued and outstanding.  All outstanding shares of the capital stock of
TM's subsidiaries have been validly issued and fully paid, and are
non-assessable and are owned by TM or one of its subsidiaries free and clear of
any liens, security interest, pledges, agreements, claims, charges, or
encumbrances of any nature whatsoever.  There are no voting trusts or other
agreements or understandings to which TM is a party with respect to the voting
of the capital stock of TM or any of its subsidiaries.  None of TM or its
subsidiaries is required to redeem, repurchase or otherwise acquire shares of
capital stock of TM, or any of its subsidiaries, respectively, as a result of
the transactions contemplated by this Agreement.  All of the outstanding TM
Shares are duly and validly issued, fully paid and nonassessable.  None of the
TM Shares or TM Preferred Stock have been issued in violation of any preemptive
or other rights of TM's shareholders.

         5.3     Authority Relative to this Agreement.  TM has the corporate
power to enter into this Agreement and to carry out its obligations hereunder.
The execution and delivery of this Agreement by TM and the consummation by TM
of the transactions contemplated hereby have been duly authorized by the Board
of Directors of TM, and, except for approval by TM's stockholders at the
meeting provided for in Section 8.4 (provided that the total vote cast at such
meeting in favor of the Merger represents over fifty percent (50%) of the
outstanding TM Shares), no other





                                      -9-
<PAGE>   10

corporate proceedings on the part of TM are necessary to approve this Agreement
or the transactions contemplated hereby.  This Agreement has been duly and
validly executed and delivered by TM and constitutes a valid and binding
agreement of TM, enforceable against TM in accordance with its terms.

         5.4     Consents and Approvals; No Violations. Except for applicable
requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended (the "HSR Act"), the Securities Act of 1933, as amended (the
"Securities Act"), the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), state securities or blue sky laws, and the filing and
recordation of a Certificate of Merger as required by the DGCL and a
Certificate of Merger as required by the GBCC, no filing with, and no permit,
authorization, consent or approval of, any public or governmental body or
authority is necessary for the consummation by TM of the transactions
contemplated by this Agreement.  Neither the execution and delivery of this
Agreement by TM, nor the consummation by TM of the transactions contemplated
hereby, nor compliance by TM with any of the provisions hereof, will (a)
conflict with or result in any breach of the Certificate of Incorporation or
Bylaws of TM or any of its subsidiaries, (b) result in a violation or breach
of, or constitute (with or without due notice or lapse of time or both) a
default (or give rise to any right of termination, cancellation or
acceleration) under, or give rise to the creation of any lien, charge, security
interest or encumbrance upon the respective properties or assets of TM or any
of its subsidiaries under, any of the terms, conditions or provisions of any
note, bond, mortgage, indenture, license, contract, agreement or other
instrument or obligation to which TM or any of its subsidiaries is a party or
by which any of them or any of their properties or assets may be bound or
affected or (c) violate any order, writ, injunction, decree, statute, rule or
regulation applicable to TM, any of its subsidiaries or any of their properties
or assets, except in the case of clauses (b) and (c) for violations, breaches
or defaults which would not have a Material Adverse Effect.

         5.5     Reports and Financial Statements.  TM has filed all reports
required to be filed with the Securities and Exchange Commission (the "SEC")
pursuant to the Exchange Act since January 1, 1993 including, without
limitation, an Annual Report on Form 10-K for the year ended December 31, 1994
(collectively, the "TM SEC Reports"), and has previously furnished or made
available to HD true and complete copies of all such TM SEC Reports (including
any amendments thereto), and will promptly deliver to HD any TM SEC Reports
(including any amendments thereto) filed between the date hereof and the
Effective Time.  None of such TM SEC Reports, as of their respective dates (as
amended through the date hereof), contained or with respect to TM SEC Reports
filed after





                                      -10-
<PAGE>   11

the date hereof, will contain, any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they
were made, not misleading.  The consolidated financial statements included in
the TM SEC Reports, in all material respects, present fairly the consolidated
financial position of TM and its subsidiaries as of the respective dates
thereof, and the results of operations and cash flow of TM and its subsidiaries
for the respective periods or as of the respective dates set forth therein, all
in conformity with generally accepted accounting principles consistently
applied during the periods involved, except as otherwise noted therein and
subject, in the case of the unaudited interim financial statements, to normal
year-end adjustments and any other adjustments described therein.

         5.6     Absence of Certain Changes or Events.  Since December 31,
1994, neither TM nor any of its subsidiaries has: (a) taken any of the actions
set forth in Sections 7.1(b), 7.1(c) or 7.1(e) hereof; (b) incurred any
material liability, except in the ordinary course of their business, consistent
with past practices; (c) suffered a change, or any event involving a
prospective change, in the business, assets, financial condition or results of
operations of TM or any of its subsidiaries which has had, or is reasonably
likely to have, individually or in the aggregate, a Material Adverse Effect
(other than as a result of changes or proposed changes in federal or state
health care (including health care reimbursement) laws or regulations of
general applicability or interpretations thereof and changes in generally
accepted accounting principles or changes after the date hereof that reasonably
should have been anticipated in light of specific disclosures in the TM
Disclosure Letter); (d) suffered a material adverse change, or any event
involving a prospective material adverse change in TM's marketing rights to the
Fetal Fibronectin Enzyme Immunoassay Test (the "ELISA Test"), the Fetal
Fibronectin Membrane Immunoassay Test (the "Membrane Test") or the Fetal
Fibronectin Dipstick Immunoassay Test (the "Rapid Assay Test") for detecting
preterm labor and membrane ruptures granted by Adeza Biomedical Corporation
("Adeza"); or (e) subsequent to the date hereof, except as permitted by Section
7.1 hereof, conducted its business and operations other than in the ordinary
course of business and consistent with past practices.

         5.7     Information in Disclosure Documents and Registration
Statement.  None of the information to be supplied by TM to be included in (a)
the Registration Statement on Form S-4 to be filed with the SEC by Newco under
the Securities Act for the purpose of registering the Newco Shares to be issued
in the Merger or pursuant to this Agreement (the "Registration Statement") or
(b) the joint proxy statement to be distributed in





                                      -11-
<PAGE>   12

connection with TM's and HD's meetings of stockholders to vote upon this
Agreement (the "Proxy Statement"), will, in the case of the Registration
Statement, at the time it becomes effective and at the Effective Time, or, in
the case of the Proxy Statement or any amendments thereof or supplements
thereto, at the time of the mailing of the Proxy Statement and any amendments
or supplements thereto, and at the time of each of the meetings of stockholders
of TM and HD to be held in connection with the Merger, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they are made, not misleading.  The Proxy
Statement (except for such portions thereof that relate only to HD) will comply
as to form in all material respects with the provisions of the Exchange Act and
the rules and regulations promulgated thereunder.

         5.8     Litigation.  As of the date of this Agreement, except to the
extent that individually and in the aggregate they would not reasonably be
expected to have a Material Adverse Effect: (i) there is no action, suit,
judicial or administrative proceeding, arbitration or investigation pending or,
to the best knowledge of TM, threatened against or involving TM or any of its
subsidiaries, or any of their respective properties or rights, before any
court, arbitrator, or administrative or governmental body; (ii) there is no
judgment, decree, injunction, rule or order of any court, governmental
department, commission, agency, instrumentality or arbitrator outstanding
against TM or any of its subsidiaries; and (iii) TM and its subsidiaries are
not in violation of any term of any judgments, decrees, injunctions or orders
outstanding against them.  The TM Disclosure Letter contains a description of
all actions, suits, proceedings, arbitrations, investigations, judgments,
decrees, injunctions or orders pending, or to the best knowledge, threatened
against or involving TM or any of its subsidiaries, or any of their respective
properties or rights.

         5.9     Contracts.

                 (a)      Each of the material contracts, instruments,
mortgages, notes, security agreements, leases, agreements or understandings,
whether written or oral, to which TM or any of its subsidiaries is a party that
relates to or affects the assets or operations of TM or any of its subsidiaries
or to which TM or any of its subsidiaries or their respective assets or
operations may be bound or subject is a valid and binding obligation of TM or
such subsidiary and in full force and effect (with respect to TM or such
subsidiary), except for where the failure to be in full force and effect would
not individually or in the aggregate, have a Material Adverse Effect.  Except
to the extent that the consummation of the transactions contemplated by this
Agreement





                                      -12-
<PAGE>   13

may require the consent of third parties, as disclosed in the TM Disclosure
Letter, there are no existing defaults by TM or any of its subsidiaries
thereunder or, to the knowledge of TM, by any other party thereto, which
defaults, individually or in the aggregate, would have a Material Adverse
Effect; and no event of default has occurred, and no event, condition or
occurrence exists, that (whether with or without notice, lapse of time or the
happening or occurrence of any other event) would constitute a default by TM or
any of its subsidiaries thereunder which default would, individually or in the
aggregate, have a Material Adverse Effect.

                 (b)      As of the date of this Agreement neither TM nor any
of its subsidiaries is a party to any oral or written (i) consulting agreement
not terminable on 60 days or less notice involving the payment of more than
$100,000 per annum, (ii) joint venture, (iii) noncompetition or similar
agreement that restricts TM or its subsidiaries from engaging in a line of
business, (iv) agreement with any executive officer or other employee of TM or
any subsidiary the benefits of which are contingent, or the terms of which are
materially altered, upon the occurrence of a transaction involving TM of the
nature contemplated by this Agreement and which provides for the payment of in
excess of $10,000, (v) agreement with respect to any executive officer of TM or
any subsidiary providing any term of employment or compensation guaranty, or
(vi) agreement or plan, including any stock option plan, stock appreciation
rights plan, restricted stock plan or stock purchase plan, any of the benefits
of which will be increased, or the vesting of the benefits of which will be
accelerated, by the occurrence of any of the transactions contemplated by this
Agreement or the value of any of the benefits of which will be calculated on
the basis of any of the transactions contemplated by this Agreement.

         5.10    Employee Benefit Plans.

                 (a)      TM has previously delivered to HD a true and complete
list of each written or formal employee benefit plan (including, without
limitation, any "employee benefit plan" as defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA")), policy
or agreement that is maintained (all of the foregoing, the "TM Plans"), or is
or was contributed to by TM or pursuant to which TM is still potentially liable
for payments, benefits or claims.  A copy of each TM Plan as currently in
effect and, if applicable, the most recent Annual Report, Actuarial Report or
Valuation, Summary Plan Description, Trust Agreement and any Determination
Letter issued by the IRS with respect thereto have heretofore been delivered to
HD or its counsel.  Neither TM nor any trade or business, whether or not
incorporated (an "ERISA Affiliate"), which together with TM would be deemed a
"single employer" within the meaning of





                                      -13-
<PAGE>   14

Section 4001 of ERISA, has maintained or contributed to any plan subject to
Title IV of ERISA or Section 412 of the Code (including any "multiemployer
plan," as defined in Section 3(37) of ERISA) during the six calendar years
preceding the date of this Agreement.

                 (b)      Each of the TM Plans that are subject to ERISA is in
substantial compliance with ERISA; each of the TM Plans intended to be
"qualified" within the meaning of Section 401(a) of the Code is so qualified;
and no event has occurred, and to TM's knowledge, there exists no condition or
set of circumstances, in connection with which TM or any ERISA Affiliate is
subject to liability (except liability for claims and funding obligations
payable in the ordinary course) under ERISA, the Code, or any other applicable
law.

                 (c)      All contributions or other amounts payable by TM or
its subsidiaries as of the Effective Time with respect to each TM Plan in
respect of current or prior plan years have been or will be (prior to the
Effective Time) either paid or accrued on the Financial Statements of TM. There
are no pending, or, to the best knowledge of TM threatened or anticipated
claims (other than routine claim for benefits) by or on behalf of or against
any of the TM Plans or any trusts related thereto.

                 (d)      No TM Plan provides benefits, including without
limitation death or medical benefits (whether or not insured), with respect to
current or former employees for periods extending beyond their retirement or
other termination of service (other than (i) coverage mandated by applicable
law, (ii) death benefits or retirement benefits under any "employee pension
plan," as that term is defined in Section 3(2) of ERISA, (iii) deferred
compensation benefits accrued as liabilities on the books of TM or the ERISA
Affiliates, or (iv) benefits the full cost of which is borne by the current or
former employee (or his or her beneficiary)).

         5.11    Taxes.  For the purposes of this section and Section 6.11, the
term "tax" shall include all taxes charges, withholdings, fees, levies,
penalties, additions, interest or other assessments imposed by any United
States federal, state or local authority or any other taxing authority on TM or
HD or any of their respective Tax Affiliates as to their respective income,
profit, franchise, gross receipts, payroll, sales, employment, worker's
compensation, use, property, withholding, excise, occupancy, environmental and
other taxes, duties or assessments of any nature, whatsoever.  TM has filed or
caused to be filed timely all material federal, state, local and foreign tax
returns required to be filed by each of it, any partnership or joint venture in
which it holds a majority interest or for which it is responsible for filing
tax returns, and any member of its





                                      -14-
<PAGE>   15

consolidated, combined, unitary or similar group (each such member a "Tax
Affiliate").  Such returns, reports and other information are accurate and
complete in all material respects.  TM has paid or caused to be paid or has
made adequate provision or set up an adequate accrual or reserve for the
payment of, all taxes shown to be due in respect of the periods for which
returns are due, and has established (or will establish at least quarterly) an
adequate accrual or reserve for the payment of all taxes payable in respect of
the period subsequent to the last of said periods required to be so accrued or
reserved.  Neither TM nor any of its Tax Affiliates has any material liability
for taxes in excess of the amount so paid or accruals or reserves so
established.  Neither TM nor any of its Tax Affiliates is delinquent in the
payment of any material amount of tax in excess of the amount reserved or
provided therefor, and no deficiencies for any tax, assessment or governmental
charge in excess of the amount reserved or provided therefor have been
threatened, claimed, proposed or assessed.  No waiver or extension of time to
assess any taxes has been given or requested and remains in effect on the date
hereof.  TM's federal and state income tax returns for all years ending on or
prior to December 31, 1991 have been audited (and such audits have been
completed) or are no longer subject to audit by reason of the applicable
statute of limitations.  All years ended subsequent to such date have never
been audited by the Internal Revenue Service or comparable state agencies.

         5.12    Compliance With Applicable Law.  TM and each of its
subsidiaries holds all licenses, franchises, permits, variances, exemptions,
orders, approvals and authorizations necessary for the lawful conduct of its
business under and pursuant to, and the business of each of TM and its
subsidiaries is not being conducted in violation of, any provision of any
federal, state, local or foreign statute, law, ordinance, rule, regulation,
judgment, decree, order, concession, grant, franchise, permit or license or
other governmental authorization or approval applicable to TM or any of its
subsidiaries, except to the extent that the failure to hold any such licenses,
franchises, permits or authorizations, or any such violation, would not,
individually or in the aggregate, have a Material Adverse Effect.

         5.13    Subsidiaries.  Exhibit 21.1 to TM's most recent Form 10-K
included in the TM SEC Reports lists all the subsidiaries of TM as of the date
of this Agreement and it indicates for each such subsidiary as of such date the
jurisdiction of incorporation or organization.  All of the outstanding shares
of capital stock or other equity interests of each of the subsidiaries (i) are
held by TM or one of such wholly-owned subsidiaries, (ii) are, in the case of
corporate subsidiaries, fully paid and nonassessable, and (iii) are owned by TM
or one of such wholly-owned subsidiaries free and clear of any claim, lien or
encumbrance.





                                      -15-

         5.14    Labor and Employment Matters. Except for instances which,
individually or in the aggregate, would not have a Material Adverse Effect: (a)

respects with all applicable laws respecting employment and employment
practices, terms and conditions of employment and wages and hours, including,
without limitation, the Immigration Reform and Control Act ("IRCA"), the Worker

employment discrimination, equal opportunity, affirmative action, worker's
compensation, occupational safety and health requirements and unemployment
insurance and related matters, and are not engaged in and have not engaged in
any unfair labor practice; (b) to the knowledge of TM, no investigation or
review by or before any governmental entity concerning any violations of any
such applicable laws is pending nor, to the knowledge of TM is any such
investigation threatened or has any such investigation occurred during the last
three years, and no governmental entity has provided any notice to TM or any of
its subsidiaries or others asserted an intention to conduct any such
investigation; (c) there is no labor strike, dispute, slowdown or stoppage
actually pending or threatened against TM or any of its subsidiaries; (d) no
union representation question or union organizational activity exists
respecting the employees of TM or any of its subsidiaries; (e) no collective
bargaining agreement exists which is binding on TM or any of its subsidiaries;
(f) neither TM nor any of its subsidiaries has experienced any material work
stoppage or other material labor difficulty; (g) there are no employees of TM
who earned more than $100,000 in 1994 and no independent contractors utilized
by TM who earned more than $100,000 from TM in 1994; and (h) in the event of
termination of the employment of any of the current officers, directors,
employees or agents of TM or any of its subsidiaries, neither TM, any of its
subsidiaries, HD, any of its subsidiaries, the Surviving Corporation, will
pursuant to any agreement or by reason of anything done prior to the Effective
Time by TM or any of its subsidiaries be liable to any of said officers,
directors, employees or agents for so-called "severance pay" or any other
similar payments or benefits, including, without limitation, postemployment
healthcare (other than pursuant to COBRA) or insurance benefits.

         5.15    Insurance.  As of the date hereof, TM and each of its
subsidiaries are insured by insurers reasonably believed by TM to be of
recognized financial responsibility against such losses and risks and in such
amounts as are customary in the businesses in which they are engaged.  All
material policies of insurance and fidelity or surety bonds insuring TM or any
of its subsidiaries or their respective businesses, assets, employees, officers
and directors are in full force and effect.  As of the date hereof, there are
no material claims by TM or any of its subsidiaries under any such policy or
instrument as to which any insurance





                                      -16-
<PAGE>   17

company is denying liability or defending under a reservation of rights clause.

         5.16    Contracts with Physicians, Hospitals, HMOs and Third Party
Providers.  TM has made available to representatives of HD copies (or in the
case where no written documentation exists, a summary of) all outstanding
contracts, partnerships, joint ventures and other arrangements or
understandings (written or oral) between (a) TM or any of its subsidiaries and
(b) any physician, hospital, HMO, other managed care organization, or other
third-party provider relating to the provision of medical or consulting
services, treatments, patient referrals or similar activities.

         5.17    Section 203 of the DGCL Not Applicable.  The provisions of
Section 203 of the DGCL will not, prior to the termination of this Agreement,
assuming the accuracy of the representations contained in Section 6.18 (without
giving effect to the knowledge qualification thereof), apply to this Agreement,
the Merger or the transactions contemplated hereby and thereby.

         5.18    Ownership of HD Shares.  As of the date hereof, neither TM
nor, to its knowledge, any of its affiliates or associates (as such terms are
defined under the Exchange Act), (i) beneficially owns, directly or indirectly,
or (ii) is a party to any agreement, arrangement or understanding for the
purpose of acquiring, holding, voting or disposing of, in each case, HD Shares,
which in the aggregate, represent ten percent (10%) or more of the outstanding
HD Shares.

         5.19    TM Rights Plan.  Neither the execution and delivery of this
Agreement nor the consummation of the transactions contemplated hereby will
trigger the exercisability of any TM Rights under the TM Rights Plan or
otherwise affect any TM Rights or obligations under the TM Rights Plan.

         5.20    No Dissenter's Rights.  No holder of TM Shares shall have any
rights to an appraisal or other remedy or any form of dissenter's rights under
the DGCL by reason of the Merger or the other transactions contemplated by this
Agreement.

         5.21    Corporate Records.  The minute books of TM, which have been

limitation, actions taken by written consent without a meeting) and contain

         5.22    TM Intellectual Property.

                 (a) TM has previously given to HD detailed information
(including, where applicable, federal registration numbers and dates of
registrations or applications for registration) concerning the following "TM
Intellectual Property": (i) all of TM's trademarks, service marks, trade names,

including all pending applications for any registrations thereof, and all
patents and copyrights used or proposed to be used by TM in its business and
all pending applications therefor; (ii) all computer software presently used by

to use in its business (including any marketing rights granted to TM under
patents owned or licensed by third parties) and has specified whether such use
is or will be pursuant to license, sublicense, agreement or permission.  Except
for instances which, individually or in the aggregate, would not have a
Material Adverse Effect:  (i) TM owns or possesses the right to use all TM
Intellectual Property now used or proposed to be used in its business; (ii) TM
has not received notice of nor has any reason to believe that TM's use of any
of the TM Intellectual Property is interfering with, infringing upon or
otherwise violating the rights of any third party in or to such TM Intellectual

a third party; and (iii) TM has not disclosed any of the TM Intellectual
Property other than in a manner reasonably that are in the aggregate necessary

                                   ARTICLE VI

                      REPRESENTATIONS AND WARRANTIES OF HD

         Each of the following representations and warranties is qualified by
the disclosure letter (the "HD Disclosure Letter") delivered to TM immediately
prior to the execution hereof, whether or not reference is made to the HD
Disclosure Letter in such representation or warranty.  Except as set forth in
the HD Disclosure Letter or in the "HD SEC Reports" (as hereinafter defined)
filed prior to the execution of this Agreement, HD represents and warrants to
TM as follows:

         6.1     Organization.  HD is a corporation duly organized, validly
existing and in good standing under the laws of the State of Georgia and has
the corporate power to carry on its business as it is now being conducted or
presently proposed to be conducted.  HD is duly qualified as a foreign
corporation to do business, and is in good standing (to the extent the concept
of good standing exists), in each jurisdiction where the character of its
properties owned or held under lease or the nature of its activities makes such
qualification necessary.  Each current subsidiary of HD which is incorporated
is a corporation duly organized, validly existing and in good standing (to the
extent the concept of good standing exists) under the laws of its jurisdiction
of incorporation or organization, has the corporate power to carry on its
business as it is now being conducted and is duly qualified as a foreign
corporation to do business, and is in good standing (to the extent the concept
of good standing exists), in each jurisdiction where the character of its
properties owned or held under lease or the nature of its activities makes such
qualification necessary.  HD has delivered to TM or its counsel complete and
correct copies of its, and its current subsidiaries', Articles of Incorporation
and Bylaws or other organizational documents.

         6.2     Capitalization.  The authorized capital stock of HD consists
of 25,000,000 shares of HD Common Stock, par value $.01 per share, and
3,000,000 shares of HD Preferred Stock, 750,000 shares of which have been
designated as Series A Cumulative Convertible Preferred Stock and which have
been redeemed, 250,000 shares of which have been designated as Series B
Cumulative Preferred Stock and 300,000 shares of which have been designated as
Series C Cumulative Preferred Stock (collectively, the "HD Preferred Stock").
As of the date hereof, 15,634,799 HD Shares





                                      -19-
<PAGE>   20

were issued and outstanding and options to acquire 2,472,293 HD Shares (the "HD
Stock Options") were outstanding under all stock option plans of HD ("HD Stock
Option Plans").  The TM Stock Options and HD Stock Options are sometimes
referred to collectively as the "Stock Options".  There are no shares of HD
Preferred Stock outstanding and 550,000 shares of HD Preferred Stock are
reserved for issuance pursuant to rights ("HD Rights") granted under HD's
Shareholder Rights Agreements (collectively, the "HD Rights Plans").  All of
the issued and outstanding HD Shares are validly issued, fully paid,
nonassessable and free of preemptive rights or similar rights created by
statute, the Articles of Incorporation or Bylaws of HD or any agreement to
which HD or any of its subsidiaries is a party or by which it is bound.  Since
December 31, 1994, HD has not issued any shares of its capital stock, except
upon the exercise of certain warrants held by Mellon Bank, stock options
previously granted under HD Stock Option Plans or Stock Purchase Plan or upon
conversion of the "Convertible Debentures" (as hereinafter defined).  HD has
reserved for issuance 272,576 HD Shares for issuance upon conversion of HD's 8%
Convertible Subordinated Debentures Due December 31, 2001 (the "Convertible
Debentures").  Except as set forth above and pursuant to HD employee benefit
plans and as otherwise provided for in this Agreement and the Rights Plans,
there are not now, and at the Effective Time there will not be, any shares of
capital stock of HD issued or outstanding or any options, warrants,
subscriptions, calls, rights, convertible securities or other agreements or
commitments obligating HD to issue, transfer or sell any shares of its capital
stock.  As of the date hereof, except for the Convertible Debentures, no Voting
Debt of HD was issued or outstanding, nor will there be any issued or
outstanding at the Effective Time.  Except as provided in this Agreement, after
the Effective Time, HD will have no obligation to issue, transfer or sell any
shares of its capital stock pursuant to any employee benefit plan or otherwise.
All outstanding shares of the capital stock of HD's current subsidiaries have
been validly issued and fully paid, and are non-assessable and owned by HD or
one of its current subsidiaries free and clear of any liens, security
interests, pledges, agreements, claims, charges, or encumbrances of any nature
whatsoever.  There are no voting trusts or other agreements or understandings
to which HD is a party with respect to the voting of the capital stock of HD or
any of its current subsidiaries.  Except for any redemption of the Rights, none
of HD or its subsidiaries is required to redeem, repurchase or otherwise
acquire shares of capital stock of HD, or any of its current subsidiaries,
respectively, as a result of the transactions contemplated by this Agreement.
All of the outstanding HD Shares are duly and validly issued, fully paid and
nonassessable.  None of the HD Shares or HD Preferred Stock have been issued in
violation of any preemptive or other rights of HD's shareholders.

         6.3     Authority Relative to this Agreement.  HD has the corporate
power to enter into this Agreement and to carry out its obligations hereunder.
The execution and delivery of this Agreement by HD and the consummation by HD
of the transactions contemplated hereby have been duly authorized by HD's Board
of Directors and, except for the approval of the holders of a majority of the
outstanding HD Shares, no other corporate proceedings on the part of HD are
necessary to approve this Agreement or the transactions contemplated hereby.
This Agreement has been duly and validly executed and delivered by HD and
constitutes a valid and binding agreement of HD, enforceable against HD in
accordance with its terms.

         6.4     Consents and Approvals; No Violations.  Except for applicable
requirements of the HSR Act, the Securities Act, the Exchange Act, state
securities or blue sky laws, and the filing and recordation of a Certificate of
Merger as required by the DGCL and a Certificate of Merger as required by the
GBCC, no filing with, and no permit, authorization, consent or approval of, any
public or governmental body or authority is necessary for the consummation by
HD of the transactions contemplated by this Agreement except where a failure to
make such filing or to obtain such permit, registration, authorization, consent
or approval will not, individually or in the aggregate, have a Material Adverse
Effect.  Neither the execution and delivery of this Agreement by HD, nor the
consummation by HD of the transactions contemplated hereby, nor compliance by
HD with any of the provisions hereof, will (a) conflict with or result in any
breach of any provisions of the Articles of Incorporation or Bylaws of HD or
any of its current subsidiaries, (b) result in a violation or breach of, or
constitute (with or without due notice or lapse of time or both) a default (or
give rise to any right of termination, cancellation or acceleration) under, or
give rise to creation of any lien, charge, security interest or encumbrance
upon, any of the respective properties or assets of HD or any of its current
subsidiaries under, any of the terms, conditions or provisions of any note,
bond, mortgage, indenture, deed of trust, license, contract, lease, agreement
or other instrument or obligation to which HD or any of its current
subsidiaries is a party or by which any of them or any of their properties or
assets may be bound or affected or (c) violate any order, writ, injunction,
decree, statute, rule or regulation of any court or government authority
applicable to HD, any of its current subsidiaries, or any of their properties
or assets, except in the case of clauses (b) and (c) for violations, breaches
or defaults which would not have a Material Adverse Effect.

         6.5     Reports and Financial Statements.  HD has filed all reports
required to be filed with the SEC pursuant to the Exchange Act since January 1,
1993 including, without limitation, an Annual Report on Form 10-K for the year
ended December 31,





                                      -21-
<PAGE>   22

1994 (collectively, the "HD SEC Reports"), and has previously furnished or made
available to TM true and complete copies of all such HD SEC Reports (including
any amendments thereto) and will promptly deliver to TM any HD SEC Reports
(including any amendments thereto) filed between the date hereof and the
Effective Time.  None of such HD SEC Reports, as of their respective dates (as
amended through the date hereof), contained or with respect to HD SEC Reports
filed after the date hereof, will contain, any untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.  The consolidated financial statements
included in the HD SEC Reports, in all material respects, present fairly the
consolidated financial position of HD and its subsidiaries as of the respective
dates thereof, and the results of operations and the cash flow of HD and its
subsidiaries for the respective periods or as of the respective dates set forth
therein, all in conformity with generally accepted accounting principles
consistently applied during the periods involved, except as otherwise noted
therein and subject, in the case of the unaudited interim financial statements,
to normal year-end adjustments and any other adjustments described therein.

         6.6     Absence of Certain Changes or Events.  Since December 31,
1994, neither HD nor any of its current subsidiaries has: (a) taken any of the
actions set forth in Sections 7.1(b), 7.1(c) or 7.1(e) hereof; (b) incurred any
material liability, except in the ordinary course of their business, consistent
with past practices; (c) suffered changes, or any event involving a prospective
change in the business, assets, financial condition or results of operations of
HD or any of its current subsidiaries which has had, or is reasonably likely to
have, individually or in the aggregate, a Material Adverse Effect (other than
as a result of changes or proposed changes in federal or state health care
(including health care reimbursement) laws or regulations of general
applicability or interpretations thereof, changes in generally accepted
accounting principles or changes after the date hereof that reasonably should
have been anticipated in light of specific disclosures in the HD Disclosure
Letter); or (d) subsequent to the date hereof, except as permitted by Section
7.1 hereof, conducted its business and operations other than in the ordinary
course of business and consistent with past practices.

         6.7     Information in Disclosure Documents and Registration
Statement.  None of the information to be supplied by HD to be included in the
Proxy Statement or the Registration Statement will, in the case of the
Registration Statement, at the time it becomes effective and at the Effective
Time, or, in the case of the Proxy Statement or any amendments thereof or
supplements





                                      -22-
<PAGE>   23

thereto, at the time of the mailing of the Proxy Statement and any amendments
or supplements thereto, and at the time of the meetings of stockholders of HD
and TM to be held in connection with the Merger, contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading.  The Proxy Statement
(except for such portions thereof that relate only to TM) will comply as to
form in all material respects with the provisions of the Exchange Act, and the
rules and regulations promulgated thereunder.

         6.8     Litigation.  As of the date of this Agreement, except to the
extent that individually and in the aggregate they would not reasonably be
expected to have a Material Adverse Effect: (i) there is no action, suit,
judicial or administrative proceeding, arbitration or investigation pending or,
to the best knowledge of HD, threatened against or involving HD and any of its
subsidiaries, or any of their respective properties or rights, before any
court, arbitrator, or administrative or governmental body; (ii) there is no
judgment, decree, injunction, rule or order of any court, governmental
department, commission, agency, instrumentality or arbitrator outstanding
against HD and any of its subsidiaries; and (iii) HD and its subsidiaries are
not in violation of any term of any judgments, decrees, injunctions or orders
outstanding against them.  The HD Disclosure Letter contains a description of
all actions, suits, proceedings, arbitrations, investigations, judgements,
decrees, injunctions or orders pending, or to the best knowledge, threatened
against or involving HD or any of its subsidiaries, or any of their respective
properties or rights.

         6.9     Contracts.

                 (a)      Each of the material contracts, instruments,
mortgages, notes, security agreements, leases, agreements or understandings,
whether written or oral, to which HD or any of its current subsidiaries is a
party that relates to or affects the assets or operations of HD or any of its
subsidiaries or to which HD or any of its subsidiaries or their respective
assets or operations may be bound or subject is a valid and binding obligation
of HD or such subsidiary and in full force and effect (with respect to HD or
such subsidiary), except for where the failure to be in full force and effect
would not, individually or in the aggregate, have a Material Adverse Effect.
Except to the extent that the consummation of the transactions contemplated by
this Agreement may require the consent of third parties, as disclosed in the HD
Disclosure Letter, there are no existing defaults by HD or any of its
subsidiaries thereunder or, to the knowledge of HD, by any other party thereto,
which defaults, individually or in the aggregate, would have a Material Adverse





                                      -23-
<PAGE>   24

Effect; and no event of default has occurred, and no event, condition or
occurrence exists, that (whether with or without notice, lapse of time or the
happening or occurrence of any other event) would constitute a default by HD or
any of its subsidiaries thereunder which default would, individually or in the
aggregate, have a Material Adverse Effect.

                 (b)      As of the date of this Agreement neither HD nor any
of its current subsidiaries is a party to any oral or written (i) consulting
agreement not terminable on 60 days or less notice involving the payment of
more than $100,000 per annum, (ii) joint venture, (iii) noncompetition or
similar agreement that restricts HD or its current subsidiaries, other than
HIE, from engaging in a line of business, (iv) agreement with any executive
officer or other employee of HD or any subsidiary the benefits of which are
contingent, or the terms of which are materially altered, upon the occurrence
of a transaction involving HD of the nature contemplated by this Agreement and
which provides for the payment of in excess of $10,000, (v) agreement with
respect to any executive officer of HD or any subsidiary providing any term of
employment or compensation guaranty, or (vi) agreement or plan, including any

vesting of the benefits of which will be accelerated, by the occurrence of any
of the transactions contemplated by this Agreement or the value of any of the
benefits of which will be calculated on the basis of any of the transactions
contemplated by this Agreement.

         6.10    Employee Benefit Plans.

                 (a)      HD has previously delivered to TM a true and complete
list of each written or formal employee benefit plan (including, without
limitation, any "employee benefit plan" as defined in Section 3(3) of ERISA),
policy or agreement that is maintained (all of the foregoing, the "HD Plans"),
or is or was contributed to by HD or pursuant to which HD is still potentially
liable for payments, benefits or claims.  A copy of each HD Plan as currently
in effect and, if applicable, the most recent Annual Report, Actuarial Report
or Valuation, Summary Plan Description, Trust Agreement and any Determination
Letter issued by the IRS with respect thereto have heretofore been delivered to
TM or its counsel.  Neither HD nor any ERISA Affiliate, which together with HD
would be deemed a "single employer" within the meaning of Section 4001 of
ERISA, has maintained or contributed to any plan subject to Title IV of ERISA
or Section 412 of the Code (including any "multiemployer plan," as defined in
Section 3(37) of ERISA) during the six calendar years preceding the date of
this Agreement.





                                      -24-
<PAGE>   25

                 (b)      Each of HD Plans that are subject to ERISA is in
substantial compliance with ERISA; each of HD Plans intended to be "qualified"
within the meaning of Section 401(a) of the Code is so qualified; and no event
has occurred, and to HD's knowledge, there exists no condition or set of
circumstances, in connection with which HD or any ERISA Affiliate is subject to
liability (except liability for claims and funding obligations payable in the
ordinary course) under ERISA, the Code or any other applicable law.

                 (c)      All contributions or other amounts payable by HD or
its subsidiaries, other than HIE and HTI, as of the Effective Time with respect
to each HD Plan in respect of current or prior plan years have been or will be
(prior to the Effective Time) either paid or accrued on the Financial
Statements of HD.  There are no pending, or, to the best knowledge of HD,
threatened or anticipated claims (other than routine claims for benefits) by or
on behalf of or against any of HD Plans or any trusts related thereto.

                 (d)      No HD Plan provides benefits, including without
limitation death or medical benefits (whether or not insured), with respect to
current or former employees for periods extending beyond their retirement or
other termination of service (other than (i) coverage mandated by applicable
law, (ii) death benefits or retirement benefits under any "employee pension
plan," as that term is defined in Section 3(2) of ERISA, (iii) deferred
compensation benefits accrued as liabilities on the books of HD or the ERISA
Affiliates, or (iv) benefits the full cost of which is borne by the current or
former employee (or his or her beneficiary)).

         6.11    Taxes.  HD has filed or caused to be filed timely all material
federal, state, local and foreign tax returns required to be filed by each of
it and its Tax Affiliates.  Such returns reports and other information are
accurate and complete in all material respects.  HD has paid or caused to be
paid or has made adequate provision or set up an adequate accrual or reserve
for the payment of, all taxes shown to be due in respect of the periods for
which returns are due, and has established (or will establish at least
quarterly) an adequate accrual or reserve for the payment of all taxes payable
in respect of the period subsequent to the last of said periods required to be
so accrued or reserved.  Neither HD nor any of its Tax Affiliates has any
material liability for taxes in excess of the amount so paid or accruals or
reserves so established.  Neither HD nor any of its Tax Affiliates is
delinquent in the payment of any material amount of tax in excess of the amount
reserved or provided therefor, and no deficiencies for any tax, assessment or
governmental charge in excess of the amount reserved or provided therefor have
been threatened, claimed, proposed or assessed.  No





                                      -25-
<PAGE>   26

waiver or extension of time to assess any taxes has been given or requested and
remains in effect on the date hereof.  HD's federal and state income tax
returns for all years ending on or prior to December 31, 1991 have been audited
(and such audits have been completed) or are no longer subject to audit by
reason of the applicable statute of limitations.  All years ended subsequent to
such date have never been audited by the Internal Revenue Service or comparable
state agencies.

         6.12    Compliance With Applicable Law.  HD and each of its current
subsidiaries holds all licenses, franchises, permits, variances, exemptions,
orders, approvals and authorizations necessary for the lawful conduct of its
business under and pursuant to, and the business of each of HD and its
subsidiaries is not being conducted in violation of, any provision of any
federal, state, local or foreign statute, law, ordinance, rule, regulation,
judgment, decree, order, concession, grant, franchise, permit or license or
other governmental authorization or approval applicable to HD or any of its
subsidiaries, except to the extent that the failure to hold any such licenses,
franchises, permits or authorizations, or any such violation, would not,
individually or in the aggregate, have a Material Adverse Effect.

         6.13    Subsidiaries.  Exhibit 21.1 to HD's most recent Form 10-K
included in HD SEC Reports lists all the current corporate subsidiaries of HD
as of the date of this Agreement (except that HTI is no longer a subsidiary)
and it indicates for each such subsidiary as of such date the jurisdiction of
incorporation or organization.  All of the shares of capital stock or other
equity interests of each of the corporate subsidiaries, other than HTI as of
the date hereof and HIE as of the Effective Time, (i) are held by HD or one of
such wholly-owned subsidiaries, (ii) are, in the case of corporate
subsidiaries, fully paid and nonassessable, and (iii) are owned by HD or one of
such wholly-owned subsidiaries free and clear of any claim, lien or
encumbrance.

         6.14    Labor and Employment Matters. Except for instances which,
individually or in the aggregate, would not have a Material Adverse Effect: (a)
HD and its subsidiaries are and have been in compliance in all material
respects with all applicable laws respecting employment and employment
practices, terms and conditions of employment and wages and hours, including,
without limitation, IRCA, WARN, and such laws respecting employment
discrimination, equal opportunity, affirmative action, worker's compensation,
occupational safety and health requirements and unemployment insurance and
related matters, and are not engaged in and have not engaged in any unfair
labor practice; (b) to the knowledge of HD, no investigation or review by or
before any governmental entity concerning any violations of any such applicable
laws is pending nor, to the knowledge of HD is any





                                      -26-
<PAGE>   27

such investigation threatened or has any such investigation occurred during the
last three years, and no governmental entity has provided any notice to HD or
any of its subsidiaries or others asserted an intention to conduct any such
investigation; (c) there is no labor strike, dispute, slowdown or stoppage
actually pending or threatened against HD or any of its subsidiaries; (d) no
union representation question or union organizational activity exists
respecting the employees of HD or any of its subsidiaries; (e) no collective
bargaining agreement exists which is binding on HD or any of its subsidiaries;
(f) neither HD nor any of its subsidiaries has experienced any material work
stoppage or other material labor difficulty; (g) there are no employees of HD
who earned more than $100,000 in 1994, and no independent contractors utilized
by HD who earned more than $100,000 in 1994; and (h) in the event of
termination of the employment of any officers, directors, employees or agents
of HD or any of its subsidiaries, neither HD, any of its subsidiaries, TM, any
of its subsidiaries, the Surviving Corporation, will pursuant to any agreement
or by reason of anything done prior to the Effective Time by HD or any of its
subsidiaries be liable to any of said officers, directors, employees or agents
for so-called "severance pay" or any other similar payments or benefits,
including, without limitation, postemployment healthcare (other than pursuant
to COBRA) or insurance benefits.

         6.15    Insurance.  As of the date hereof, HD and each of its current
corporate subsidiaries are insured by insurers reasonably believed by HD to be
of recognized financial responsibility against such losses and risks and in
such amounts as are customary in the businesses in which they are engaged.  All
material policies of insurance and fidelity or surety bonds insuring HD or any
of its current subsidiaries or their respective businesses, assets, employees,
officers and directors are in full force and effect.  As of the date hereof,
there are no material claims by HD or any of its current subsidiaries under any
such policy or instrument as to which any insurance company is denying
liability or defending under a reservation of rights clause.

         6.16    Contracts with Physicians, Hospitals, HMOs and Third Party
Providers.  HD has made available to representatives of TM copies (or in the
case where no written documentation exists, a summary of) all outstanding
contracts, partnerships, joint ventures and other arrangements or
understandings (written or oral) between (a) HD or any of its current
subsidiaries, and (b) any physician, hospital, HMO, other managed care
organization, or other third-party provider relating to the provision of
medical or consulting services, treatments, patient referrals or similar
activities.

         6.17    Section 14-2-1110 of the GBCC Not Applicable.  The provisions
of Section 14-2-1110 of the GBCC will not, prior to the termination of this
Agreement and the transactions contemplated hereby, assuming the accuracy of
the representations contained in Section 5.18 (without giving effect to the
knowledge qualification thereof), apply to this Agreement, the Merger or the
transactions contemplated hereby.

         6.18    Ownership of TM Shares.  As of the date hereof, neither HD
nor, to its knowledge, any of its affiliates or associates (as such terms are
defined under the Exchange Act), (a) beneficially owns, directly or indirectly,
or (b) is a party to any agreement, arrangement or understanding for the
purpose of acquiring, holding, voting or disposing of, in each case, TM Shares,
which in the aggregate, represent ten percent (10%) or more of the outstanding
TM Shares.

         6.19    HD Rights Plans.  Neither the execution and delivery of this
Agreement nor the consummation of the transactions contemplated hereby will
trigger the exercisability of any HD Rights under the HD Rights Plans or
otherwise affect any HD Rights or obligations under the HD Rights Plans.

         6.20    No Dissenter's Rights.  No holder of HD Shares shall have any
rights to an appraisal or other remedy or any form of dissenter's rights under
the GBCC by reason of the Merger or the other transactions contemplated by this
Agreement.

         6.21    Corporate Records.  The minute books of HD, which have been
made available to TM or its representatives, fully and accurately show in all
material respects all corporate action taken by HD's Board of Directors, all
committees of HD's Board of Directors and HD's shareholders (including, without
limitation, actions taken by written consent without a meeting) and contain
true and complete copies or originals of the Articles of Incorporation (and all
amendments thereto) of HD, the Bylaws (as amended) of HD and the minutes of all
meetings or consent actions of HD's Board of Directors, committees of HD's
Board of Directors and HD's shareholders.  As of the date of this Agreement, no
resolutions material to HD or bylaws of HD have been passed, enacted, consented
to or adopted by HD's Board of Directors, committees of HD's Board of Directors
or HD's shareholders except as set forth in such minute books.

         6.22    HD Intellectual Property.  HD has previously given to TM
detailed information (including, where applicable, federal registration numbers
and dates of registrations or applications for registration) concerning the
following "HD Intellectual Property": (a) all of HD's trademarks, service
marks, trade names, and other trade rights, indicating which are registered and
which are not, including all pending applications for any





                                      -28-
<PAGE>   29

registrations thereof, and all patents and copyrights used or proposed to be
used by HD in its business and all pending applications therefor; (b) all
computer software presently used by HD which has been purchased or licensed
from outside parties with a purchase price or license fee in excess of $5,000;
and (c) all other trade secrets, designs, plans, specifications and other
intellectual property rights of HD (whether or not registered or registrable).
HD has also identified any of such HD Intellectual Property that any third
party owns and that HD uses or proposes to use in its business (including any
marketing rights granted to HD under patents owned or licensed by third
parties) and has specified whether such use is or will be pursuant to license,
sublicense, agreement or permission.  Except for instances which, individually
or in the aggregate, would not have a Material Adverse Effect:  (i) HD owns or
possesses the right to use all HD Intellectual Property now used or proposed to
be used in its business; (ii) HD has not received notice of nor has any reason
to believe that HD's use of any of HD Intellectual Property is interfering
with, infringing upon or otherwise violating the rights of any third party in
or to such HD Intellectual Property or that any of such HD Intellectual
Property was misappropriated from a third party; and (iii) HD has not disclosed
any of HD Intellectual Property other than in a manner reasonably necessary for
the operation of its business.  HD has not granted any licenses of or other
rights to use any of HD Intellectual Property to any third party.  HD
Intellectual Property comprises all of the intellectual property rights that
are in the aggregate necessary in any material respect for the operation of its
business as it is presently conducted.

         6.23    Opinion of Financial Advisor.  HD has received the opinion of
Needham & Company, Inc. to the effect that, as of the date hereof, the exchange
ratio set forth in Section 4.1(b) is fair to the holders of HD Shares.

         6.24    HIE Spinoff Registration Statement.  The registration
statement filed with the SEC relating to the spinoff of HIE common stock to HD
shareholders ("HIE Spinoff") will not, at the time it becomes effective and on
the effective date of the HIE Spinoff, contain any untrue statement of a
material fact, or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading.

                 (d)      Each of HD and TM shall use its best efforts to
preserve intact the business organization of HD and its subsidiaries on the one
hand and TM and its subsidiaries on the other hand to keep available the
services of its and their present officers and key employees, and to preserve
the goodwill of those having business relationships with it and their
respective subsidiaries; provided, however, that no breach of this
representation shall be deemed to have occurred if a failure to comply with
this Section 7.1(d) occurs as a result of any matter arising out of the
transactions contemplated by this Agreement or any "Acquisition Proposals" (as
defined in Section 8.2 below) made to HD or TM or the public announcement
thereof or, to the extent set forth on Schedule 7.1, as a result of the
purchase of any unincorporated subsidiary of HD or S corporation or

                 (e)      Neither HD, TM nor any of their respective
subsidiaries shall knowingly take or allow to be taken or fail to take any
action which act or omission would jeopardize qualification of the merger as a

                 (f)      Neither HD, TM nor any of their respective
subsidiaries shall fail to use all reasonable efforts to take or omit to take
any action or agree, in writing or otherwise, to take or omit to take any
action which would make any representation or warranty of HD or TM, as
applicable, herein untrue or incorrect in any material respect.

                 7.2      Compensation Plans.  Except as set forth in Schedule
7.2 hereto, during the period from the date of this Agreement and continuing
until the Effective Time, each of HD and TM agrees as to itself and its
subsidiaries that it will not, without the prior written consent of the other
party hereto (except as otherwise required by applicable law or pursuant to
existing contractual arrangements) (a) enter into, adopt or amend any bonus,
profit sharing, compensation, stock option, pension, retirement, deferred
compensation, employment, severance or other employee benefit plan, agreement,
trust, plan, fund or other arrangement between HD or TM, as applicable, and one
or more of its officers, directors or employees, in each case so as to
materially increase benefits thereunder (collectively, "Compensation Plans"),
(b) grant or become obligated to grant any increase in the compensation or
fringe benefits of directors, officers or employees (including any such

payable or to become payable to any officer, except, with respect to employees
other than officers, for increases in compensation in the ordinary course of
business consistent with past practice, or enter into any contract, commitment
or arrangement to do any





                                      -31-
<PAGE>   32

of the foregoing, except for normal increases and non-stock benefit changes in

change in any Compensation Plan or other employee welfare or benefit
arrangement or enter into any employment or similar agreement or arrangement

         7.3     Current Information.  From the date of this Agreement to the
Effective Time, each of HD and TM will cause one or more of its designated
representatives to confer on a regular and frequent basis (not less frequently
than semimonthly) with representatives of the other and to report the general
status of its ongoing operations and to deliver to the other (not less
frequently than monthly) unaudited consolidated balance sheets and related
consolidated statements of income, changes in stockholders equity and cash flow
for the period since the last such report.  Each of HD and TM will promptly
notify the other of any material change in the normal course of business or in
its or its subsidiaries' properties.

         7.4     Legal Conditions to Merger.  Each of HD and TM shall, and
shall cause its subsidiaries to, use all reasonable efforts (a) to take, or

requirements which may be imposed on such party or its subsidiaries with
respect to the Merger and to consummate the transactions contemplated by this
Agreement, subject to the appropriate vote or consent of stockholders and (b)
to obtain (and to cooperate with the other party to obtain) any consent,
authorization, order or approval of, or any exemption by, any governmental
entity and or any other public or private third party which is required to be
obtained or made by such party or any of its subsidiaries in connection with
the Merger and the transactions contemplated by this Agreement; provided,
however, that a party shall not be obligated to take any action pursuant to the
foregoing if the taking of such action or such compliance or the obtaining of
such consent, authorization, order, approval or exemption would, in such
party's reasonable opinion, (i) be materially burdensome to such party and its
subsidiaries taken as a whole or impact in such a materially adverse manner the
economic or business benefits of the transactions contemplated by this
Agreement as to render inadvisable the consummation of the Merger or (ii) to
result in the imposition of a condition or restriction on such party or on the
Surviving Corporation of the type referred to in Section 9.1(e). Each of HD and
TM will promptly cooperate with and





                                      -32-
<PAGE>   33

furnish information to the other in connection with any such burden suffered
by, or requirement imposed upon, any of them or any of their subsidiaries in
connection with the foregoing.

         7.5     Affiliates.

                 (a)      At least 15 days prior to the mailing of the Proxy
Statement to stockholders of HD and TM, HD shall deliver to Newco a letter
identifying all persons who are, at the time this Agreement is submitted for
approval to the stockholders of HD and TM, "affiliates" of HD for purposes of
Rule 145 under the Securities Act.  HD shall use all reasonable efforts to
cause each person named in the letter delivered by it to deliver to Newco by
the time of the mailing of the Proxy Statement a written "affiliates"
agreement, in customary form, restricting the disposition by such person of the
Newco Shares to be received by such person in the Merger to dispositions
permitted by Rule 145.  Certificates surrendered for exchange by any person
constituting an "affiliate" of HD within the meaning of Rule 145 under the
Securities Act shall not be exchanged by the Exchange Agent for Newco Shares
pursuant to Section 4.2 until Newco has received such agreement described in
the preceding sentence.

                 (b)      At least 15 days prior to the mailing of the Proxy
Statement to stockholders of HD and TM, TM shall deliver to Newco a letter
identifying all persons who are, at the time this Agreement is submitted for
approval to the stockholders of HD and TM, "affiliates" of TM for purposes of
Rule 145 under the Securities Act.  TM shall use all reasonable efforts to
cause each person named in the letter delivered by it to deliver to Newco by
the time of the mailing of the Proxy Statement a written "affiliates"
agreement, in customary form, restricting the disposition by such person of the
Newco Shares to be received by such person in the Merger to dispositions
permitted by Rule 145.  Certificates surrendered for exchange by any person
constituting an "affiliate" of TM within the meaning of Rule 145 under the
Securities Act shall not be exchanged by the Exchange Agent for Newco Shares
pursuant to Section 4.2 until Newco has received such agreement described in
the preceding sentence.

                 (c)      The affiliates agreements referred to in this Section
7.5 shall also provide for certain demand registration or piggy back
registration rights in favor of such affiliates as described on Exhibit C
hereto.

         7.6     Advice of Changes; Government Filings.  Each party shall
confer on a regular and frequent basis with the other, report on operational
matters and promptly advise the other orally and in writing of any change or
event having, or which, insofar as can reasonably be foreseen, could have, a
Material Adverse Effect on such party or which would cause or constitute a





                                      -33-
<PAGE>   34

material breach of any of the representations, warranties or covenants of such
party contained herein.  TM and HD shall file all reports required to be filed
by each of them with the SEC between the date of this Agreement and the
Effective Time and shall deliver to the other party copies of all such reports
promptly after the same are filed.  Except where prohibited by applicable
statutes and regulations, each party shall promptly provide the other (or its
counsel) with copies of all other filings made by such party with any state of
federal government entity in connection with this Agreement or the transactions
contemplated hereby.

         7.7     Accounting Methods.  Neither TM nor HD shall change its
methods of accounting in effect at December 31, 1994, except as required by
changes in generally accepted accounting principles as concurred in by such
party's independent auditors.  Neither TM nor HD shall change its fiscal year.


                                  ARTICLE VIII

                             ADDITIONAL AGREEMENTS

         8.1     Access and Information.

                 (a)      HD and TM and their respective subsidiaries shall
each afford to the other and to the other's financial advisors, legal counsel,
accountants, consultants and other representatives access during normal
business hours throughout the period from the date hereof to the Effective Time
to all of its books, records, properties, facilities, personnel commitments and
records (including but not limited to tax returns) and, during such period,
each shall furnish promptly to the other all information concerning its
business, properties and personnel as such other party may reasonably request.
No investigation pursuant to this Section 8.1 shall affect any representations
or warranties made herein or the conditions to the obligations of the
respective parties to consummate the Merger.

                 (b)      All information furnished by HD to TM or furnished by
TM to HD pursuant hereto shall be treated as the sole property of the party
furnishing the information until consummation of the Merger contemplated
hereby.  The parties will hold any such information which is nonpublic in
confidence to the extent required by, and in accordance with the
Confidentiality Agreement dated as of February 11, 1994, between HD and TM (the

         8.7     Employee Benefit Plans.  Each of HD and TM hereby confirms to
Newco that all Stock Options which are not fully vested as of the date of this
Agreement provide for acceleration of vesting or exercisability upon the
Merger, and TM and HD agree not to take any action to prevent such acceleration
of vesting pursuant to the terms of such Stock Options.

         8.8     Stock Options.  As of the Effective Time, Newco shall assume
the Options Plans of each of TM and HD and the Stock Options outstanding under
such plans as of the Effective Time (the "Assumed Option").  Each Assumed
Option shall be exercisable for the number of Newco Shares equal to the number
of TM or HD shares subject to such option prior to the Effective Time, at the
exercise price per Newco Share equal to the exercise price per TM or HD share
applicable to such Assumed Option immediately prior to the Effective Time
(without taking into account any anti-dilution formula); provided, however,
that in the case of any Employee Stock Option to which Section 421 of the Code
applies by reason of its qualification under Section 422 of the Code, the
conversion formula shall be adjusted, if necessary, to comply with Section
424(a) of the Code.  Except as provided above, each Assumed Option shall
continue to have and be subject to the same terms and conditions as were
applicable to such option immediately prior to the Effective Time except that
each such Assumed Option held by an optionee who continues his service with TM
or HD up to the Effective Time shall be exercisable for all of shares subject
to such option as fully-vested Newco Shares.  Any repurchase rights of TM and
HD with respect to (y) unvested TM and HD shares previously issued upon
exercise of options granted under the Option Plans or (z) unvested Newco Shares
issuable upon exercise of the Assumed Options, shall not be assigned to Newco.
Newco agrees that as soon as reasonably practicable after the Effective Time it
will cause to be filed one or more registration statements on Form S-8 under
the Securities Act, or amendments to any registration statements on Form S-8
covering its stock options to register the Newco Shares issuable upon exercise
of the Assumed Options, and at or prior the Effective Time, Newco shall take
all corporate action necessary to reserve for issuance a sufficient number of
Newco Shares for delivery upon exercise of the Assumed Options.  The
consummation of the Merger shall not of itself be treated as a termination of
an optionee's service with TM or HD for purposes of the Assumed Options or the
Option Plans.

         8.9     Convertible Debentures.  As of the Effective Time, each of the
Convertible Debentures which is outstanding both as of the date hereof and at
the Effective Time shall be assumed by Newco by execution and delivery of a
supplemental indenture, pursuant to which Newco shall agree to issue Newco
Shares upon conversion of the Convertible Debentures in accordance with the
terms hereof.

                 (a)      From and after the Effective Time, the Surviving
Corporation shall indemnify, defend and hold harmless to the fullest extent
permitted under applicable law each person who is now, or has been at any time
prior to the date hereof, an officer, director, employee, trustee or agent of
TM or HD (or any subsidiary or division thereof), including, without
limitation, each person controlling any of the foregoing persons (individually,
an "Indemnified Party" and collectively the "Indemnified Parties"), against all
losses, claims, damages, liabilities, costs or expenses (including attorneys'
fees), judgments, fines, penalties and amounts paid in settlement in connection
with any claim, action, suit, proceeding or investigation arising out of or
pertaining to acts or omissions, or alleged acts or omissions, by them in their
capacities as such, whether commenced, asserted or claimed before or after the
Effective Time, arising under the Securities Act, the Exchange Act and state
corporation laws in connection with the Merger.  In the event of any such
claim, action, suit, proceeding or investigation (an "Action"), (i) the
Surviving Corporation shall pay the reasonable fees and expenses of counsel
selected by the Indemnified Party, which counsel shall be reasonably acceptable
to the Surviving Corporation, in advance of the final disposition of any such
action to the fullest extent permitted by applicable law, upon receipt of any
undertaking required by applicable law, and (ii) the Surviving Corporation
shall cooperate in the defense of any such matter; provided, however, that the
Surviving Corporation shall not be liable for any settlement effected without
its written consent (which consent shall not be unreasonably withheld) and
provided, further, that the Surviving Corporation shall not be obligated
pursuant to this Section 8.10 to pay the fees and disbursements of more than
one counsel for all Indemnified Parties in any single Action except to the
extent that in the opinion of counsel for the Indemnified Parties two or more
of such Indemnified Parties have conflicting interest in the outcome of such
action.

                 (b)      The Surviving Corporation shall keep in effect
provisions in its Certificate of Incorporation and Bylaws providing for
exculpation of director and officer liability and indemnification of the
Indemnified Parties to the fullest extent permitted under the DGCL, which
provisions shall not be amended except as required by applicable law or except
to make changes permitted by law that would enlarge the Indemnified Parties'
right of indemnification.

                 (c)      For a period of six years after the Effective Time,
the Surviving Corporation shall cause to be maintained officers' and directors'
liability insurance covering the Indemnified Parties (who are currently covered
in their





                                      -38-
<PAGE>   39

capacities as officers and directors by the existing officers's and directors'
liability insurance policies of TM or HD) with respect to Claims arising from
facts or which occurred on or before the Effective Time on terms substantially
no less advantageous to the Indemnified Parties than such existing insurance;
provided, however, that the Surviving Corporation shall not be required in
order to maintain or procure such coverage to pay an annual premium in excess
of three times the larger of the current annual premium paid by TM and HD,
respectively, for its coverage (the "Cap"); and provided, further, that if
equivalent coverage cannot be obtained, or can be obtained only by paying an
annual premium in excess of the Cap, the Surviving Corporation shall only be
required to obtain as much coverage as can be obtained by paying an annual
premium equal to the Cap.

                 (d)      The Surviving Corporation shall pay all expenses,
including attorneys' fees, that may be incurred by any Indemnified Parties in
enforcing the indemnity and other obligations provided for in Section 8.10(a).

                 (e)      The rights of each Indemnified Party hereunder shall
be in addition to any other rights such Indemnified Party may have under the
Certificate of Incorporation or Bylaws of the Surviving Corporation, under the
DGCL or otherwise.  The Provisions of this Section 8.10 shall survive the
consummation of the Merger and expressly are intended to benefit each of the
Indemnified Parties.

         8.11    Public Announcements.  So long as this Agreement is in effect,
TM, on the one hand, and HD, on the other hand, agree that they will each
obtain the approval of the other party prior to issuing any press release and
that they will use their best efforts to consult with one another before
otherwise making any public statement or responding to any press inquiry with
respect to this Agreement or the transactions contemplated hereby, except as
may be required by law or any governmental agency if required by such agency or
the rules of the National Association of Securities Dealers, Inc.

         8.12    Expenses.  In the event the Merger is consummated, all costs
and expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be assumed and paid by the Surviving Corporation.  In
the event the Merger is not consummated, all costs and expenses incurred in
connection with this Agreement and the transactions contemplated hereby shall
be paid by the party incurring such expenses, except as provided by Article X
and except that TM and HD shall share equally:  (i) the expenses incurred in
connection with filing, printing and mailing the Proxy Statement and the
Registration Statement; and (ii) all





                                      -39-

                       TERMINATION, AMENDMENT AND WAIVER

         10.1    Termination.  This Agreement may be terminated and the Merger

or warranty which would have or would be reasonably likely to have a Material
Adverse Effect on HD or (ii) any material covenant or agreement set forth in

<PAGE>   50

resolved to do the same, provided however that TM may not terminate this
Agreement pursuant to this clause (e), if, as a result of HD's receipt of an
Acquisition Proposal from a third party, HD withdraws, modifies or amends its
approval or recommendation of the transactions contemplated hereby and if HD
publicly reconfirms its recommendation of the transactions contemplated hereby
and notifies TM of such reconfirmation prior to termination of this Agreement
by TM pursuant to this clause;

                 (f)      By HD if the Board of Directors of TM shall have
withdrawn or modified in a manner adverse to HD its approval or recommendation
of this Agreement or the Merger, or shall have resolved to do the same,
provided however that HD may not terminate this Agreement pursuant to this
clause (f), if, as a result of TM's receipt of an Acquisition Proposal from a
third party, TM withdraws, modifies or amends its approval or recommendation of

decree, ruling or any other action shall have become final and non-appealable;

                 (h)      By either TM or HD upon written notice to the other

<PAGE>   51

of TM that TM must recommend or approve such Acquisition Proposal; provided

in Section 8.1 hereof and except for Sections 8.12 and 10.3 hereof which shall
survive the termination).  Except as otherwise provided in Section 10.3(c),
nothing contained in this Section 10.2 shall relieve any party from liability

Agreement.  Upon request therefor, each party will redeliver all documents,
work papers and other material of any other party relating to the transactions
contemplated hereby, whether obtained before or after the execution hereof, to
the party furnishing same.

         10.3    Cancellation Fee; Expenses.

                 (a)      If with respect to either TM or HD (each a "Subject
Company"), (i) after the date hereof any third party shall have become the
beneficial owner of ten percent (10%) or more of the shares of Common Stock of
the Subject Company outstanding at the time of such acquisition (other than
acquisitions for bona fide arbitrage purposes only); (ii) the Subject Company
shall have entered into an agreement, including without limitation an agreement
in principle, with respect to an Acquisition Proposal, other than the

and obtain proxies or consents from the Subject Company's stockholders
representing a majority of the outstanding shares of Common Stock of the
Subject Company with respect to an acquisition of control of the Subject
Company (other than solicitations relating to this Agreement) or with respect
to a stockholder proposal aimed at preventing or recommending against
consummation of this Agreement or any related transaction and such third party
shall successfully use such proxies or consents to acquire control of the
Subject Company or to defeat the Merger and the Subject Company shall enter
into an agreement, including without limitation, an agreement in principle with
respect to an Acquisition Proposal within six months thereafter; or (iv) the
Subject Company shall breach any of the provisions of Section 8.2 above or
shall recommend or approve an Acquisition Proposal pursuant to Section 8.2 and,
in either case, this Agreement is terminated pursuant to Section 10.1(c),
Section 10.1(d), Section





                                      -51-
<PAGE>   52

10.1(e), Section 10.1(f), Section 10.1(i) or Section 10.1(j); then such Subject
Company ("Payor Company") shall pay to the other Subject Company ("Receiving
Company") a fee in cash or immediately available funds of Five Million Five
Hundred Thousand Dollars ($5,500,000) (the "Cancellation Fee"); provided,
however, that no such Cancellation Fee shall be payable with respect to clauses
(i) through (iii) above if the applicable event otherwise triggering the
Cancellation Fee occurs after this Agreement has been terminated pursuant to
Section 10.1(a), Section 10.1(b), Section 10.1(c), Section 10.1(d), Section
10.1(g) or Section 10.1(h) hereof.

                 (b)      The Payor Company shall pay to the Receiving Company
the Cancellation Fee provided in Section 10.3(a) above within ten (10) days of
written demand therefor by the Receiving Company.  The payment of the
Cancellation Fee shall be conditioned on there being no material breach of the
obligations of the Receiving Company hereunder.  If the Payor Company fails to
pay any amount due the Receiving Company pursuant to this Section 10.3 when
due, the Payor Company shall pay interest thereon, from the date due until the
date paid in full, at the Prime Rate as announced from time to time by Bank of
America or any successor thereto (the "Prime Rate") and shall reimburse the
Receiving Company for all reasonable attorneys' fees and other costs and
expenses incurred by the Receiving Company in collecting such amount from the
Payor Company.

                 (c)      Notwithstanding anything herein to the contrary,
payment of the Cancellation Fee as provided in subsections (a) and (b) of this
Section 10.3 and payment of the Expense Reimbursement Payment as provided in
Section 10.3(d), when required, shall constitute full settlement of any and all
liabilities and obligations of the Payor Company under this Agreement, except
for liabilities arising from the fraud or willful misconduct of the Payor
Company.

                 (d)      In the event that either HD or TM terminates this
Agreement pursuant to, respectively, Section 10.1(c) or Section 10.1(d) hereof,
then the nonterminating party shall pay to the terminating party One Million
Dollars ($1,000,000) representing full payment of the terminating party's
reasonable out-of-pocket expenses incurred in connection with the negotiation,
execution and performance of this Agreement ("Expense Reimbursement Payment");
provided, however, that the terminating party shall not be entitled to any
Expense Reimbursement Payment pursuant to this Section 10.3(d) if at the time
of termination the nonterminating party also would have been entitled to
terminate this Agreement pursuant to Section 10.1(c) or Section 10.1(d), as
applicable.  In addition, if the stockholders of TM or HD fail to approve the
merger and this Agreement is terminated by HD or TM pursuant to Section
10.1(h), then the party whose stockholders





                                      -52-
<PAGE>   53

have so failed to approve the Merger shall pay to the other party hereto the
Expense Reimbursement Payment; provided, however, that no such Expense
Reimbursement Payment shall be due under this sentence if the stockholders of
the party which would have otherwise been entitled to such Expense
Reimbursement Payment have previously failed to approve the Merger at the
stockholders meeting called for that purpose.

         10.4    Amendment.  This Agreement may be amended by action taken by
TM and HD at any time before or after approval hereof by the stockholders of HD
and TM, but, after any such approval, no amendment shall be made which alters
the number of Newco Shares to be exchanged for each Share of TM or HD or which
in any way materially adversely affects the rights of such stockholders,
without the further approval of such stockholders.  This Agreement may not be
amended except by an instrument in writing signed on behalf of each of the
parties hereto.

         10.5    Waiver.  At any time prior to the Effective Time, the parties
hereto may (a) extend the time for the performance of any of the obligations or
other acts of the other parties hereto, (b) waive any inaccuracies in the
representations and warranties,contained herein or in any document delivered
pursuant hereto and (c) waive compliance with any of the agreements or
conditions contained herein.  Any agreement on the part of a party hereto to
any such extension or waiver shall be valid only if set forth in an instrument
in writing signed on behalf of such party.  Such waiver shall not operate as a
waiver of, or estoppel with respect to, any subsequent or other failure.

                 1209 Orange Street
                 Wilmington, New Castle County, Delaware 19801]

                                  ARTICLE III

         The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the General Corporation
Law of the State of Delaware.

                                   ARTICLE IV

         The Corporation shall have authority to issue [____________] shares of
stock, consisting of _____________ shares of Common Stock, par value [$0.01]
per share, and ______________ shares of Preferred Stock, par value [$0.01] per
share.

                                   ARTICLE V

         The shares of Preferred Stock may be issued from time to time in one
or more series.  The Board of Directors is authorized to fix by resolution the
designations, powers, preferences and relative, participating, optional or
other special rights (including voting rights, if any, and conversation rights,
if any), and qualifications, limitations or restrictions thereof, of any such
series of Preferred Stock, and the number of shares constituting any such
series, or all or any of them; and to increase or decrease the number of shares
of any series subsequent to the issue of shares of that series, but not below
the number of such shares then outstanding.  Except as otherwise provided (i)
by law, (ii) by this Certificate of Incorporation as amended from time to time,
or (iii) by resolutions of the Board of Directors fixing the powers and
preferences of any class or series of shares as to which the Board of Directors
has been expressly vested with authority to fix the powers and preferences, (a)

                                   ARTICLE VI

         The business and affairs of the Corporation shall be managed and
controlled by a Board of Directors.  The number of directors constituting the
Board of Directors shall be fixed, initially, by the Bylaws of the Corporation;
thereafter the number of directors shall be fixed or altered exclusively by
resolutions adopted by the Board of Directors.  The directors shall be divided
into three classes as nearly equal in number as possible, designated Class I,
Class II and Class III.  The initial term of office of Class I directors shall

1997 annual meeting of stockholders; and of Class III directors at the 1998
annual meeting of stockholders.  At each annual meeting of stockholders,
successors to the class of directors whose terms of office expire in that year
shall be elected to hold office for a term of three years.  Each director shall
hold office until his successor is elected and qualified or until his earlier
resignation.  No decrease in the number of directors shall shorten the term of
any incumbent director.  Elections of directors need not be by ballot unless
the Bylaws so provide.

                                  ARTICLE VII

         In furtherance and not in limitation of the powers conferred by law,
the Board of Directors is authorized to adopt, amend or repeal the Bylaws of
the Corporation, subject to the restrictions, if any, contained in the Bylaws
of the Corporation, and subject to the further restriction that, until [three
years from the Effective Time], Sections 3.2, 3.14 and 3.15 of the Bylaws can
only be amended by the affirmative vote of the holders of at least [a majority
of] the Common Stock of the Corporation.

                                  ARTICLE VIII

         To the fullest extend permitted by the General Corporation Law of the
State of Delaware, as the same exists or may hereafter be amended, a director
of the Corporation shall not be liable to the Corporation or its stockholders
for monetary damages for breach of fiduciary duty as a director.  The liability
of a director of the Corporation to the Corporation or its stockholders for
monetary damages shall be eliminated to the fullest extent permissible under
applicable law in the event it is determined that Delaware law does not apply.
The Corporation shall, to the fullest extent permitted by law, indemnify its
directors and officers against any liabilities, losses or related expenses
which they may incur by reason of serving or having served as directors or
officers of the Corporation, or serving or having served at the request of the
Corporation as directors, officers, trustees, partners, employees or agents of
any entity in which the Corporation has an interest.  The Corporation is
authorized to provide by Bylaw, agreement or otherwise for indemnification of
directors, officers, employees and agents in excess of the indemnification
otherwise permitted by applicable law.  Any repeal or modification of this
Article shall not result in any liability of a director, or any





                                      -2-
<PAGE>   60

change or reduction in the indemnification to which a director, officer,
employee or agent would otherwise be entitled, with respect to any action or
omission occurring prior to such repeal or modification.

                                   ARTICLE IX

         Any action required or permitted to be the taken by holders of stock
of the Corporation must be taken at a meeting of such holders and may not be
taken by consent in writing, except (i) as permitted by resolutions of the
Board of Directors fixing the powers and preferences of any class or series of
shares as to which the Board of Directors has been expressly vested with
authority to fix the powers and preferences, or (ii) for the purposes of
approving, authorizing or adopting any action or proposal theretofore approved,
authorized or adopted by the Board of Directors.

                        AGREEMENTS REGARDING AFFILIATES

                 2.1      Limitation on Transfer.  In connection with the
issuance of the Common Shares to the Initial Holders and in accordance with
Section 7.5 of the Merger Agreement, each Initial Holder severally, and not
jointly, represents, warrants and agrees as follows:

                 (a)      Such Holder shall not make any sale, transfer or
         other disposition of the Common Shares held by such Holder in
         violation of the Securities Act or the Rules and Regulations.

                 (b)      Such Holder has been advised that the issuance of
         Common Shares to such Holder as a result of the Merger has been
         registered with the Commission under the Securities Act on a
         Registration Statement on Form S-4.  However, such Holder has also
         been advised that, because at the time the Merger was submitted for a
         vote of the stockholders of HD or TM, as applicable, such Holder may
         have been an "affiliate" of HD or TM, as applicable, and the
         distribution by such Holder of the Common Shares such Holder receives
         as a result of the Merger has not been registered under the Securities
         Act, such shares must be held by such Holder indefinitely unless (i)
         such distribution of such shares has been registered under the
         Securities Act, (ii) a sale of such shares is made in conformity with
         the provisions of Rule 145 promulgated by the Commission under the
         Securities Act or (iii) such sale is pursuant to a transaction which,
         in the opinion of counsel reasonably satisfactory to Newco or as
         described in a "no-action" or interpretive letter from the staff of
         the Commission, is not required to be registered under the Securities
         Act.

                 (c)      Such Holder has carefully read this Agreement and the
         Merger Agreement and has discussed the requirements of the Merger
         Agreement and other limitations upon the sale, transfer or other
         disposition of the Common Shares to be received by such Holder, to the
         extent such Holder has felt necessary, with such Holder's counsel.

                 2.2      Registration and Legends.  In connection with the
matters set forth in this Article 2 such Holder understands and agrees that:

                 (a)      Newco is under no further obligation to register the
         sale, transfer or other disposition of the Common Shares received by
         such Holder as a result of the Merger or to take any other action
         necessary in order to make compliance with an exemption from
         registration available, except as set forth in Section 2.3 or Article
         3 below.

                 (b)      Stop transfer instructions will be given to the
         transfer agents of Newco with respect to the Common Shares such Holder
         will receive as a result of the Merger, and there will be placed on
         the certificates representing such shares, or any certificates
         delivered in substitution therefor, a legend stating in substance:

                          "The shares represented by this certificate were
                 issued in a transaction to which Rule 145 under the Securities
                 Act of 1933 applies.  The shares represented by this
                 certificate may be transferred only in accordance with the
                 terms of an agreement dated _______________, 1995, between the
                 registered holder hereof and Tokos/Healthdyne Acquisition
                 Company, Inc., a copy of which agreement is on file at the
                 principal offices of Tokos/Healthdyne Acquisition Company,
                 Inc."

                 (c)      Unless the transfer by such Holder of such Holders'
         Common Shares is a sale made in conformity with the provisions of Rule
         145 of the Rules and Regulations or made pursuant to a registration
         under the Securities Act, Newco reserves the right to put the
         following legend on the certificates issued to such Holder's
         transferee:

                          "The shares represented by this certificate have not
                 been registered under the Securities Act of 1933 and were
                 acquired by the holder not with a view to, or for resale in
                 connection with, any distribution thereof within the meaning
                 of the Securities Act of 1933 and may not be sold, pledged or
                 otherwise transferred except pursuant to a registration
                 statement or in accordance with an exemption from the
                 registration requirements of the Securities Act of 1933."

                 It is understood and agreed that the legends set forth above
         shall be removed and substitute certificates shall be delivered
         without any such legend and the transfer agents will be instructed to
         effectuate transfers of Common Shares if the Holder delivers to Newco
         a letter from the staff of the Commission or an opinion of counsel in
         form and substance reasonably satisfactory to Newco to the effect that
         such legend is not required for the purposes of the Securities Act.

                 2.3      Filings by Newco.  Newco hereby represents, warrants
and agrees that for as long as resales of any Common Shares owned by any Holder
are subject to Rule 145, Newco will use all reasonable efforts to make all
filings of the nature specified in paragraph (c)(1) of Rule 144 of the Rules
and Regulations.

                                   ARTICLE 3

                            SECURITIES REGISTRATION

                 3.1      Demand Registration.  (a)  The Holders shall have the
         right, during the period (the "Registration Period") commencing on the
         date of this Agreement and ending on the second anniversary of the
         date of this Agreement, by written notice (the "Demand





                                       5
<PAGE>   66

         Notice") given to Newco, to request Newco to register under and in     
         accordance with the provisions of the Securities Act all or any portion
         of the Registrable Stock designated by such Holders; provided,
         however, that the aggregate number of shares of Registrable Stock
         requested to be registered pursuant to any Demand Notice and pursuant
         to any related Demand Notices received pursuant to the following
         sentence shall be at least [300,000 shares].  Upon receipt of any such
         Demand Notice, Newco shall promptly notify all other Holders of the
         receipt of such Demand Notice and allow them the opportunity to include
         Registrable Stock held by them in the proposed registration by
         submitting their own Demand Notice.  In connection with any Demand
         Registration in which more than one Holder participates, in the event
         that such Demand Registration involves an underwritten offering and the
         managing underwriter or underwriters participating in such offering
         advise in writing the Holders of Registrable Stock to be included in
         such offering that the total number of shares of Registrable Stock to
         be included in such offering exceeds the amount that can be sold in (or
         during the time of) such offering without delaying or jeopardizing the
         success of such offering (including the price per share of the
         Registrable Stock to be sold), then the amount of Registrable Stock to
         be offered for the account of such Holders shall be reduced pro rata on
         the basis of the number of shares of Registrable Stock to be registered
         by each such Holder.  The Holders as a group shall be entitled to three
         Demand Registrations pursuant to this Section 3.1 unless any Demand
         Registration does not become effective or is not maintained for a
         period (whether or not continuous) of at least 180 days (or such
         shorter period as shall terminate when all the Registrable Stock
         covered by such Demand Registration have been sold pursuant thereto),
         in which case the Holders will be entitled to an additional Demand
         Registration pursuant hereto.

                 (b)      Newco, within 60 days of the date on which the
         Company receives a Demand Notice given by Holders in accordance with
         Section 2(a) hereof, shall file with the SEC, and Newco shall
         thereafter use its best efforts to cause to be declared effective, a
         Registration Statement on the appropriate form for the registration
         and sale in accordance with the intended method or methods of
         distribution, of the total number of shares of Registrable Stock
         specified by the Holders in such Demand Notice (subject to the
         limitations set forth in Section 2(a) hereof), which, at the option of
         Newco, may include a "shelf" registration pursuant to Rule 415 under
         the Securities Act (a "Demand Registration").

                 (c)      Newco shall use commercially reasonable efforts to
         keep each Registration Statement filed pursuant to this Section 3.1
         continuously effective and usable for the resale of the Registrable
         Stock covered thereby (i) for a period of 180 days from the date on
         which the SEC declares such Registration Statement effective or (ii)
         until all the Registrable Stock covered by such Registration Statement
         have been sold pursuant to such Registration Statement, if earlier, in
         either case, as such period may be extended pursuant to this Section
         3.1.

                 (d)      Newco shall be entitled to postpone the filing of any
         Registration Statement otherwise required to be prepared and filed by
         Newco pursuant to this Section 3.1, or suspend the use of any
         effective Registration Statement under this Section 3.1 (a
         "Suspension"), for a reasonable period of time, but not in excess of
         90 days (a "Delay Period"), if the Board of Directors or the Executive
         Committee of the Board of Directors of Newco determines that in its
         reasonable judgment and good faith the registration and distribution
         of the Registrable Stock covered or to be covered by such Registration
         Statement would materially interfere with any pending financing,
         acquisition or corporate reorganization or other corporate development
         involving Newco or any of its subsidiaries or would require premature
         disclosure thereof, and Newco gives the Holders requesting such
         registration written notice of such determination within five business
         days after the date of such determination, containing a general
         statement of the reasons for such postponement and an approximation of
         the anticipated delay; provided, however, that (i) the aggregate
         number of days included in all Delay Periods during any consecutive 12
         months shall not exceed 180 days and (ii) a period of at least 60 days
         shall elapse between the termination of any Delay Period and the
         commencement of the immediately succeeding Delay Period.  If Newco
         shall so postpone the filing of a Registration Statement, the Holders
         of Registrable Stock to be registered shall have the right to withdraw
         the request for registration by giving written notice from the Holders
         of a majority of the Registrable Stock that were to be registered to
         Newco within 45 days after receipt of the notice of postponement or,
         if earlier, the termination of such Delay Period (and, in the event of
         such withdrawal, such request shall not be counted for purposes of
         determining the number of Demand Registrations to which the Holders of
         Registrable Stock are entitled pursuant to this Section 3.1).  The
         time period for which the Company is required to maintain the
         effectiveness of any Registration Statement shall be extended by the
         aggregate number of days of all Delay Periods resulting from
         Suspensions.

                 (e)      In the case of a proposed firm commitment
         underwritten offering pursuant to a Demand Registration, Newco may
         include other Newco securities in the related Registration Statement,
         if of the same type as the Registrable Stock covered by such
         Registration Statement, for the account of other security holders, if
         any, who have piggyback registration rights with respect thereto, on
         the same terms and conditions as the Registrable Stock.  Newco shall
         give the managing underwriter or underwriters participating in such
         offering written notice or its intent to include any such Newco
         securities in such Registration within 10 days of receipt of the
         initial Demand Notice applicable to such Registration.
         Notwithstanding the foregoing, if the managing underwriter or
         underwriters participating in such offering conclude that the total
         amount of Newco securities proposed to be included in such Demand
         Registration exceeds the amount which can be sold in (or during the
         time of) such offering without delaying or jeopardizing the success of
         such offering (including the price per share of the securities to be
         sold), then the amount of securities to be offered for the account of
         all holders other than the Holders shall be reduced (to zero if
         necessary) to an amount recommended by such managing underwriter or
         underwriters.

                 (f)      Holders of a majority in number of the shares of
         Registrable Stock to be included in a Registration Statement pursuant
         to this Section 3.1 may, at any time prior to the effective date of
         the Registration Statement relating to such Registration, revoke such
         request by providing a written notice to Newco revoking such request.
         The Holders of Registrable Stock who revoke such request shall
         reimburse Newco for all its out-of-pocket expenses incurred in the
         preparation, filing and processing of the Registration Statement;
         provided, however, that, if such revocation was based on Newco's
         failure to comply in any material respect with its obligations
         hereunder, such reimbursement shall not be required.  A withdrawal of
         a request for registration following notice from Newco of a Delay
         Period shall not be deemed a revocation of such request if it is made
         within the time period specified for such withdrawal in Section 3.1(d)
         above.

         3.2     Piggyback Registration.  If Newco at any time during the
Registration Period proposes to file a registration statement under the
Securities Act with respect to the public offering of securities of the same
type as the Registrable Stock pursuant to a firm commitment underwritten
offering solely for cash (other than a registration relating either to (a) a
dividend reinvestment, employee stock option, stock purchase or similar plan,
(b) a merger, consolidation or reorganization, or (c) any other transaction
pursuant to Rule 145 under the Securities Act), Newco shall each such time give
written notice (the "Newco Notice"), at its expense, to each Holder then having
registration rights hereunder of its intention to do so at least 30 days prior
to the filing of a registration statement with respect to such registration
with the Commission.  If any such Holder desires to dispose of all or part of
its Registrable Stock in connection therewith, it shall deliver to Newco,
within 10 days after the giving of the Newco Notice, written notice of such
desire (the "Holder's Notice") stating the number of shares of Registrable
Stock to be disposed of by such Holder.  Newco shall use all reasonable efforts
to cause all shares of Registrable Stock specified in such Holders' Notices to
be included in the offering so as to permit the sale by such Holder or Holders
all of the shares of Registrable Stock referred to in such Holders' Notices,
subject, however, to the limitations set forth in Section 3.3 hereof.

         3.3     Limitations on Piggyback Registration Rights.

                 (a)      If Newco or the managing underwriter or underwriters
         participating in any offering under Section 3.2 advise the Holders in
         writing that the total amount of securities requested to be included
         in such Piggyback Registration exceeds the amount which can be sold in
         (or during the time of) such offering without delaying or jeopardizing
         the success of such offering (including the price per share of the
         securities to be sold), then the amount of securities to be offered
         for the account of the Holders and other holders of securities who
         have piggyback registration rights with respect thereto shall be
         reduced (to zero if necessary) pro rata on the basis of the number of
         common stock equivalents requested to be registered by each such
         Holder or holder participating in such offering.

                 (b)      Newco may, for any reason and without the consent of
         or liability to any Holder determine at any time not to proceed with
         any registration which is the subject of a Newco Notice and abandon
         the proposed offering, whereupon Newco shall be relieved of any
         further obligation hereunder to proceed with such registration or
         offering.

         3.4     Registration Procedures.

                 (a)      In connection with the registration by Newco of
         shares of Registrable Stock pursuant to Section 3.1 above, or in
         connection with the inclusion of shares of Registrable Stock in any
         offering of securities of Newco pursuant to Section 3.2 above, Newco
         shall:

                          (i)  prepare and file with the Commission a
                 registration statement with respect to such securities on such
                 form as Newco deems appropriate and is permitted or qualified
                 under the Rules and Regulations to use and use all reasonable
                 efforts to cause such registration statement to become and
                 remain effective as provided herein; provided that, in the
                 case of any registration pursuant to Section 3.2, such
                 preparation and filing may be delayed in the sole discretion
                 of Newco, without prejudice to the rights of any of the
                 Holders pursuant to Section 3.1 hereof;

                          (ii)  prepare and file with the Commission such
                 amendments and supplements to such registration statement and
                 the prospectuses used in connection therewith as may be
                 necessary to keep such registration statement effective and
                 current and to comply with the provisions of the Securities
                 Act with respect to the sale or other disposition of all
                 shares covered by such registration statement, including such
                 amendments and supplements as may be necessary to reflect the
                 intended method of disposition from time to time of the
                 Holders who have requested that any of their shares be sold or
                 otherwise disposed of in connection with any registration
                 pursuant to Section 3.2 or whose shares of Registrable Stock
                 are included in any registration pursuant to Section 3.1 (in
                 either such case, the "Prospective Sellers"), until the
                 earlier of (A) such time as all of the securities covered by
                 such registration statement have been disposed of in
                 accordance with the intended methods of disposition by the
                 seller or sellers thereof or (B) the end of the Registration
                 Period;

                          (iii)  notify the Prospective Sellers and confirm
                 such advice in writing, (A) when such registration statement
                 becomes effective, and (B) of the entry of any stop order
                 suspending the effectiveness of such registration statement or
                 the initiation of any proceedings for that purpose, and, if
                 such stop order shall be entered, Newco shall use its
                 reasonable efforts promptly to obtain the lifting thereof;





                                       9
<PAGE>   70

                          (iv)  furnish to the Prospective Sellers at a
                 reasonable time prior to the filing thereof with the
                 Commission a copy of the registration statement in the form in
                 which Newco proposes to file the same; not later than one day
                 prior to the filing thereof, a copy of any amendment
                 (including any post-effective amendment) to such registration
                 statement; and promptly following the effectiveness thereof, a
                 conformed copy of the registration statement as declared
                 effective by the Commission and of each post-effective
                 amendment thereto, including financial statements and all
                 exhibits and reports incorporated therein by reference;

                          (v)  furnish to each Prospective Seller such number
                 of copies of each prospectus, including preliminary
                 prospectuses, in conformity with the requirements of the
                 Securities Act, and such other documents, as the Prospective
                 Seller may reasonably request in order to facilitate the
                 public sale or other disposition of the shares owned by it;

                          (vi)  use all reasonable efforts to register or
                 qualify the shares covered by such registration statement
                 under such other securities or Blue Sky or other applicable
                 laws of such jurisdictions as each Prospective Seller shall
                 reasonably request to enable such seller to consummate the
                 public sale or other disposition of the shares owned by such
                 seller; provided that Newco shall not be required in
                 connection therewith or as an election thereto to qualify to
                 do business or to file a general consent to service of process
                 in any such jurisdiction, or to maintain the effectiveness of
                 any such registration or qualification for any period during
                 which it is not required to maintain the effectiveness of the
                 related registration statement under the Securities Act as set
                 forth in Section 3.4(a)(ii);

                          (vii)  use all reasonable efforts to cause all such
                 shares of Registrable Stock to be listed on each securities
                 exchange or other securities trading market on which Common
                 Stock issued by Newco is then listed;

                          (viii)    enter into such customary agreements
                 (including an underwriting agreement in customary form with
                 respect to underwritten offerings) in form and substance
                 reasonably acceptable to Newco and take such other customary
                 actions as Prospective Sellers may reasonably request in order
                 to expedite or facilitate the disposition of such Registrable
                 Stock; and

                          (ix)  make reasonably available for inspection by any
                 Prospective Seller, any underwriter participating in any
                 disposition of Registrable Stock, and any attorney, accountant
                 or other agent retained by any such seller or underwriter, all
                 financial and other records, pertinent corporate documents and
                 properties of Newco, and use all reasonable efforts to cause
                 Newco's officers, directors and employees to supply all
                 information reasonably requested by any such seller,
                 underwriter, attorney, accountant or agent in connection with
                 the registration

<PAGE>   71

                 contemplated by Section 3.1 or Section 3.2 above, in each case
                 as and to the extent necessary to permit the Prospective
                 Sellers to conduct a reasonable investigation within the
                 meaning of the Securities Act.  To minimize disruption and
                 expense to Newco during the course of the registration
                 process, all Prospective sellers shall, to the extent
                 practicable, coordinate their investigation and due diligence
                 efforts hereunder and, to the extent practicable, will act
                 through a single set of counsel and a single set of
                 accountants and will enter into confidentiality agreements
                 with Newco in form and substance reasonably satisfactory to
                 Newco and such Prospective Sellers prior to receiving any
                 confidential or proprietary information of Newco.

                          (b)     Each Prospective Seller shall furnish to
                 Newco in writing such information as Newco may reasonably
                 request from such Prospective Seller for use in preparing the
                 registration statement (and the prospectus included therein)
                 and performing its other obligations hereunder.

                          (c)     During such time as the Prospective Sellers
                 may be engaged in a distribution of the Registrable Stock, the
                 Prospective Sellers shall comply with Rules 10b-6 and 10b-7
                 promulgated under the Securities Exchange Act of 1934, as
                 amended (the "Exchange Act"), and pursuant thereto, shall,
                 among other things:  (i) not engage in any stabilization
                 activity in connection with the securities of Newco in
                 contravention of such Rules; (ii) distribute the Registrable
                 Stock solely in the manner described in the registration
                 statement; (iii) cause to be furnished to each underwriter,
                 broker or agent through whom the Registrable Stock may be
                 offered, or to the offeree if an offer is not made through a
                 broker, such copies of the Prospectus and any amendment or
                 supplement thereto and documents incorporated by reference
                 therein as may be required by law; and (iv) not bid for or
                 purchase any securities of Newco or attempt to induce any
                 person to purchase any securities of Newco other than as
                 permitted under the Exchange Act.

         3.5     Expenses of Registration.  All expenses incurred in effecting
any registration and/or sale of Registrable Stock pursuant to this Agreement,
including, without limitation, all registration and filing fees, listing fees,
printing expenses, expenses of compliance with Blue Sky laws, fees and
disbursements of counsel for Newco, expenses of any audits incidental to or
required by any such registration, and expenses of all marketing and
promotional efforts requested by any underwriter shall be borne by Newco;
provided, however, that each Prospective Seller shall bear underwriting
discounts or brokerage fees or commissions relating to the sale of its
Registrable Stock and all fees and expenses of its own counsel, accountants and
other experts with respect to any registration and/or sale of Registrable Stock
pursuant to this Agreement.

         3.6     Indemnification.

                 (a)      Newco shall indemnify and hold harmless each
         Prospective Seller, each underwriter (as defined in the Securities
         Act), each other selling agent who may be deemed to be an underwriter,
         and each controlling person of any Prospective Seller, underwriter or
         other selling agent, if any (within the meaning of the Securities
         Act), against any losses, claims, damages or liabilities, joint or
         several (or actions in respect thereof) ("Losses"), to which such
         indemnified party may be subject under the Securities Act, under any
         other statute or at common law, but only to the extent such Losses
         arise out of or are based upon (i) any untrue statement (or alleged
         untrue statement) of any material fact contained in (x) any
         registration statement under which Registrable Stock held by such
         Prospective Seller was registered under the Securities Act or offered
         for sale, (y) any preliminary prospectus (if used prior to the
         effective date of such registration statement), or (z) any final
         prospectus or any post-effective amendment or supplement thereto (if
         used during the period Newco is required to keep the registration
         statement effective), in each case, on the effective date of such
         registration statement or post-effective amendment, or the date of
         such prospectus, including any preliminary prospectus, or supplement
         (the "Disclosure Documents"), (ii) any omission (or alleged omission)
         to state therein a material fact required to be stated therein or
         necessary to make the statements made therein not misleading or (iii)
         any violation by Newco of the Securities Act or any Blue Sky law, or
         any rule or regulation promulgated under the Securities Act or any
         Blue Sky law, or any other law, applicable to Newco in connection with
         the sale, registration or qualification of any shares of Registrable
         Stock held by such Prospective Seller; and Newco shall reimburse each
         such indemnified party for any legal or other expenses reasonably
         incurred by such party in connection with investigating or defending
         any such loss, claim, damage, liability or action, whether or not
         resulting in any liability, or in connection with any investigation or
         proceeding by any governmental agency or instrumentality relating to
         any such claims with respect to any offering of securities pursuant to
         this Article 3, but excluding any amounts paid in settlement of any
         action, suit, arbitration, proceeding, litigation, or investigation
         (collectively "Litigation"), commenced or threatened, if such
         settlement is effected without the prior written consent of Newco,
         which consent shall not be unreasonably withheld; provided, however,
         that Newco shall not be liable to any Prospective Seller, underwriter,
         other selling agent or controlling person in any such case to the
         extent that any such Losses arise out of or are based upon (i) an
         untrue statement or omission or alleged omission (y) made in any such
         Disclosure Documents in reliance upon and in conformity with written
         information furnished to Newco by or on behalf of such indemnified
         party expressly for use in the preparation thereof and so designated
         by such indemnified party, or (z) made in any preliminary prospectus
         if a copy of the final prospectus was not delivered to the person
         alleging any loss, claim, damage or liability for which Losses arise
         at or prior to the written confirmation of the sale of such
         Registrable Stock to such person and the untrue statement or omission
         concerned had been corrected in such final prospectus and copies
         thereof had timely been delivered by Newco to such indemnified party;
         or (ii) the use of any prospectus after such time as Newco has advised
         such indemnified party that the





                                       12
<PAGE>   73

         filing of a post-effective amendment or supplement thereto is
         required, except the prospectus as so amended or supplemented, or the
         use of any prospectus after such time as the obligation of Newco to
         keep the same current and effective has expired.

                 (b)  In connection with the registration and/or sale of any
         shares of Registrable Stock pursuant to this Agreement, each
         Prospective Seller shall, and (except as to clause (iii) below) shall
         cause any underwriter retained by it who participates in the offering
         to, indemnify and hold harmless Newco, each of its directors, each of
         its officers who have signed such Registration Statement and each
         controlling person of Newco (within the meaning of the Securities
         Act), against any Losses, joint or several, to which such indemnified
         party may become subject under the Securities Act, under any other
         statute or at common law, but only to the extent such Losses arise out
         of or are based upon (i) any untrue statement (or alleged untrue
         statement) of any material fact contained in any of the Disclosure
         Documents or any omission or alleged omission to state therein a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading, if the statement or omission was
         made in reliance upon and in conformity with written information
         furnished to Newco by or on behalf of such indemnifying party
         expressly for use in the preparation thereof and so designated by such
         indemnifying party; (ii) the use by such indemnifying party of any
         prospectus after such time as Newco has advised such indemnifying
         party that the filing of a post-effective amendment or supplement
         thereto is required, except the prospectus as so amended or
         supplemented, or after such time as the obligation of Newco to keep
         the registration statement effective and current has expired, or (iii)
         any information given or representation made by such indemnifying
         party in connection with the sale of Registrable Stock which is not
         contained in and not in conformity with the prospectus (as amended or
         supplemented at the time of the giving of such information or making
         of such representation); and such indemnifying party shall reimburse
         each such indemnified party for any legal and other expenses
         reasonably incurred by such party in investigating or defending any
         such loss, claim, damage, liability or action, whether or not
         resulting in any liability, or in connection with any investigation or
         proceeding by any governmental agency or instrumentality relating to
         any such claims with respect to any offering of securities pursuant to
         this Article 3, but excluding any amounts paid in settlement of any
         Litigation, commenced or threatened, if such settlement is effected
         without the prior written consent of such indemnifying party.
         Notwithstanding the provisions of this Section 3.6(b), the
         indemnification obligation of a Prospective Seller shall be limited to
         the amount in excess of the amount by which the total price at which
         the Registrable Stock sold by it exceeds the amount of any damages
         which such Prospective Seller has otherwise been required to pay by
         reason of such untrue or alleged untrue statement or omission or
         alleged omission.

                 (c)      If the indemnification provided for in Section 3.6(a)
         or (b) above is unavailable to an indemnified party in respect of any
         Losses referred to therein, then the intended indemnifying party, in
         lieu of indemnifying such indemnified party thereunder, shall
         contribute to the amount paid or payable by such indemnified party as
         a result of





                                       13
<PAGE>   74

         such Losses in such proportion as is appropriate to reflect the
         relative fault of the intended indemnifying party on the one hand and
         of the indemnified party on the other in connection with the
         statements or omissions which resulted in such Losses, as well as any
         other relevant equitable considerations.  The relative fault of the
         intended 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 or alleged
         omission to state a material fact relates to information supplied by
         (or omitted to be supplied by) the intended 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.

                 Newco and the Holders agree that it would not be just and
         equitable if contribution pursuant to this Section 3.6(c) were
         determined by pro rata allocation or by any other method of allocation
         which does not take into account the equitable considerations referred
         to in the immediately preceding paragraph.  The amount paid or payable
         by an indemnified party as a result of the losses, claims, damages and
         liabilities or actions in respect thereof referred to in the
         immediately preceding paragraph shall be deemed to include, subject to
         the limitations set forth above, any legal or other expenses
         reasonably incurred by such indemnified party in connection with
         investigating or defending any such action or claim.  Notwithstanding
         the provisions of this Section 3.6(c), no Prospective Seller shall be
         required to contribute any amount in excess of the amount by which the
         total price at which the Registrable Stock sold by it exceeds the
         amount of any damages which such Prospective Seller has otherwise been
         required to pay by reason of such untrue or alleged untrue statement
         or omission or alleged omission.  No person guilty of fraudulent
         misrepresentations (within the meaning of Section 11(f) of the
         Securities Act) shall be entitled to contribution from any person who
         was not guilty of such fraudulent misrepresentation.

                 (d)      Promptly after receipt by an indemnified party under
         Section 3.6(a) or (b) above of notice of the commencement of any
         action, such indemnified party shall, if a claim in respect thereof is
         to be made under such Section, notify the indemnifying party in
         writing of the commencement thereof; but the omission so to notify the
         indemnifying party shall not relieve it from any liability which it
         may have to any indemnified party otherwise than under such Section or
         to the extent that it has not been prejudiced as a proximate result of
         such failure.  In case any such action shall be brought against any
         indemnified party, and it shall notify the indemnifying party of the
         commencement thereof, the indemnifying party shall be entitled to
         participate therein and, to the extent that it shall wish, to assume
         the defense thereof, in each case jointly with any other indemnifying
         parties and with counsel reasonably satisfactory to such indemnified
         party; provided, however, that, if the defendants in any such action
         include both the indemnified party and the indemnifying party and
         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
         indemnified party or parties shall





                                       14
<PAGE>   75

         have the right to select separate counsel to defend such action (in
         which case the indemnifying party shall not have the right to direct
         the defense of such action on behalf of the indemnified party or
         parties).  Upon the permitted assumption by the indemnifying party of
         the defense of such action, and approval by the indemnified party of
         counsel, the indemnifying party shall not be liable to such
         indemnified party under this Section 3.6 for any legal or other
         expenses subsequently incurred by such indemnified party in connection
         with the defense thereof (other than reasonable costs of
         investigation) unless (i) the indemnified party shall have employed
         separate counsel in accordance with the proviso to the next preceding
         sentence, (ii) the indemnifying party shall not have employed counsel
         reasonably satisfactory to the indemnified party to represent the
         indemnified party within a reasonable time, or (iii) the indemnifying
         party has authorized the employment of counsel for the indemnified
         party at the expense of the indemnifying party.  It is understood,
         however, that the indemnifying party shall not, in respect of the
         legal expenses of any indemnified party in connection with any action
         or related actions in the same jurisdiction arising out of the same
         general allegations or circumstances, be liable for the fees and
         expenses of more than one separate law firm (in addition to any local
         counsel) for all indemnified parties.

         3.7  Holdback Agreements.

                 (a)      Notwithstanding any provision of this Agreement to
         the contrary, in the event Newco notifies the Prospective Sellers that
         Newco intends to file a registration statement in connection with an
         underwritten offering of any of its capital stock and provided that
         each executive officer of Newco agrees to substantially similar
         restrictions, each Prospective Seller shall refrain from selling or
         otherwise distributing any Registrable Stock within the period
         beginning up to seven days prior to the effective date of such
         registration statement (or on such later date that Newco notifies the
         Prospective Sellers that such period has begun) and ending up to 120
         days after such effective date (or on such earlier date that Newco
         notifies the Prospective Sellers that such period has ended) (the
         "Offering Restricted Period") except as part of such offering as set
         forth herein.  Newco's obligation under Section 3.4(a)(ii) to keep a
         registration statement filed pursuant to Section 3.1 current and
         effective shall be extended for a number of days equal to the Offering
         Restricted Period, or, if earlier, until the date on which all of the
         Registrable Stock has been disposed of.

                 (b)      Notwithstanding anything set forth herein to the
         contrary, in the event that Newco notifies the Prospective Sellers
         that Newco desires to amend the registration statement or to
         supplement the prospectus in order to disclose material information
         required to be disclosed in the prospectus included in such
         registration statement, as then in effect, in order to correct an
         untrue statement of a material fact or to disclose an omitted material
         fact that is required to be stated therein or necessary to make the
         statements therein not misleading in light of the circumstances then
         existing, the Prospective Sellers shall refrain from selling
         Registrable Stock until Newco notifies the Prospective Sellers that
         the required amendment or supplement has been filed with the





                                       15
<PAGE>   76

         Commission (the "Disclosure Restricted Period").  Newco's obligation
         under Section 3.4(a)(ii) to keep a registration statement filed
         pursuant to Section 3.1 current and effective shall be extended for a
         number of days equal to the Disclosure Restricted Period, or, if
         earlier, until the date on which all of the Registrable Stock has been
         disposed of.  Newco shall use its reasonable efforts to file such
         amendment or supplement as promptly as practicable after Newco decides
         to amend the registration statement or supplement the prospectus.

                                   ARTICLE 4

cumulative and not exclusive of any rights, remedies, powers and privileges
provided by law.  The failure of any party to insist upon a strict performance
of any of the terms or provisions of this Agreement, or to exercise any option,
right or remedy herein contained, shall not be construed as a waiver or as a
relinquishment for the future of such term, provision, option, right or remedy,
but the same shall continue and remain in full force and effect.

                                  Andrew D. Simons


          3.          HD reserves the right to enter into, prior to the
                      Effective Time, an Amended and Restated Severance
                      Compensation and Restrictive Covenant Agreement with
                      Frank Powers to be substantially similar to the
                      agreements referred to in Item 1 above.


          4.          HD reserves the right to (i) pay bonuses earned as of
                      December 31, 1995, under its 1995 Management Incentive
                      (Bonus) Plans without regard to continued employment
                      after the Merger, and (ii) establish after consultation
                      with TM a special retention bonus and/or severance

          6.          Assuming HD's independent auditors confirm it will not
                      have any material adverse effect, HD will take such
                      action as may be required so that no Assumed Option held
                      by a former officer or director of HD shall terminate
                      prior to the twelfth month after the Effective Time
                      unless the final expiration





<PAGE>   80

                      date of the HD option so assumed would have occurred
                      prior thereto without regard to early termination for any
                      reason.
B.        TM

                      Agreements* held by the following officers, such
                      Amendments to be substantially similar to the Amendment
                      No. 1 for Robert Byrnes provided to HD**:

                                  Robert F. Byrnes
                                  Terry P. Bayer

          2.          TM intends to consider the implementation of a Retirement
                      Benefit Award program for its senior management that is
                      substantially similar to the HD Retirement Benefit
                      Program.


          3.          TM reserves the right to (i) pay bonuses earned as of
                      December 31, 1995, under its 1995 Management Bonus
                      Programs, and (ii) establish after consultation with HD a

                      employees of TM determined to be "at risk" of resignation
                      prior to the Effective Date.


          4.          The Compensation Committee of TM's Board of Directors may
                      determine, in advance of the Effective Time, to
                      accelerate the vesting of outstanding TM Stock Options
                      held by an optionee who continues in service with TM up
                      to the Effective Time.  In any event, consistent with
                      Section 8.8 of the Merger Agreement, all outstanding TM
                      Stock Options held by an optionee who continues his
                      service with TM up to the Effective Time will accelerate,
                      not later than the Effective Time, to become fully
                      vested.


                      *           The final form of such agreement will be
                                  provided by HD or TM, as the case may be, to
                                  the other party on or before the execution of
                                  the Merger Agreement.

                      **          These agreements, while they are being
                                  entered into with TM and HD, as the case may
                                  be, will only become effective upon the
                                  effectiveness of the Merger.

person or persons; provided, however, that if and to the extent that any
special meeting of stockholders may be called by any other person or persons
specified in any provisions of the Certificate of Incorporation or any
amendment thereto, or any certificate filed under Section 151(g) of the
Delaware General Corporation Law (or its successor statute as in effect from
time to time hereafter), then such special meeting may also be called by the
person or persons in the manner, at the times and for the purposes so
specified.  Business transacted at any special meeting of stockholders shall be
limited to the purposes stated in the notice.

          SECTION 2.4  STOCKHOLDER LISTS.  The officer who has charge of the
stock ledger of the Corporation shall prepare and make, at least ten (10) days
before every meeting of stockholders, a complete list of stockholders entitled
to vote at the meeting, arranged in alphabetical order, and showing the address
of each stockholder and the number of shares registered in the name of each
stockholder.  Such list shall be open to the examination of any stockholder,
for any purpose germane to the meeting, during ordinary business hours, for a
period of at least ten (10) days prior to the meeting, either at a place within
the city where





                                       2
<PAGE>   88

the meeting is to be held, which place shall be specified in the notice of the
meeting or at the place of the meeting, and the list shall also be available at
the meeting during the duration thereof, and may be inspected by any
stockholder who is present.

          SECTION 2.5  NOTICE OF MEETINGS.  Notice of each meeting of
stockholders, whether annual or special, stating the place, date and hour of
the meeting and, in the case of a special meeting, the purpose or purposes for
which such meeting has been called, shall be given to each stockholder of
record entitled to vote at such meeting not less than ten (10) nor more than
sixty (60) days before the date of the meeting, except that where the matter to
be acted on is a merger or consolidation of the Corporation or a sale, lease or
exchange of all or substantially all of its assets, such notice shall be given
not less than twenty (20) nor more than sixty (60) days prior to such meeting.
Except as otherwise expressly required by law, notice of any adjourned meeting
of the stockholders need not be given if the time and place thereof are
announced at the meeting at which the adjournment is taken.

          Whenever any notice is required to be given under the provisions of
applicable law or of the Certificate of Incorporation or of these Bylaws, a
waiver thereof in writing, signed by the person or persons entitled to said
notice,whether before or after the time stated therein, shall be deemed
equivalent thereto.  Notice of any meeting of stockholders shall be deemed
waived by any stockholder who shall attend such meeting in person or by proxy,
except a stockholder who shall attend such meeting for the express purpose of
objecting, at the beginning of the meeting, to the transaction of any business
because the meeting is not lawfully called or convened.

          SECTION 2.6  QUORUM AND ADJOURNMENT.  The holders of a majority of
the stock issued and outstanding and entitled to vote thereat, present in
person or represented by proxy, shall constitute a quorum for holding all
meetings of stockholders, except as otherwise provided by applicable law or by
the Certificate of Incorporation; provided, however, that the stockholders
present at a duly called or held meeting at which a quorum is present may
continue to transact business until adjournment notwithstanding the withdrawal
of enough stockholders to leave less than a quorum, if any action taken (other
than adjournment) is approved by at least a majority of the shares required to
constitute a quorum.  If it shall appear that such quorum is not present or
represented at any meeting of stockholders, the Chairman of the meeting shall
have power to adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present or represented.
At such adjourned meeting at which a quorum shall be present or represented,
any business may be transacted which might have been transacted at the meeting
as originally noticed.  If the adjournment is for more than thirty (30) days,
or if after the adjournment a new record date is fixed for the adjourned
meeting, a notice of the adjourned meeting shall be given to each stockholder
of record entitled to vote at the meeting.  The Chairman of the meeting may
determine that a quorum is present based upon any reasonable evidence of the
presence in person or by proxy of stockholders holding a majority of the
outstanding votes, including without limitation, evidence from any record of
stockholders who have signed a register indicating their presence at the
meeting.

          SECTION 2.7  VOTING.  In all matters, when a quorum is present at any
meeting, the vote of the holders of a majority of the capital stock having
voting power present in person or represented by proxy shall decide any
question brought before such meeting, unless the question is one upon which by
express provision of applicable law or of the Certificate of Incorporation, a
different vote is required in which case such express provision shall govern
and control the decision of such question.  Such vote may be by voice or by
written ballot; provided, however, that the Board may, in its discretion,
require a written ballot for any vote, and further provided that all elections
for directors must be by written ballot upon demand made by a stockholder at
any election and before the voting begins.

          Unless otherwise provided in the Certificate of Incorporation each
stockholder shall at every meeting of the stockholders be entitled to one vote
in person or by proxy for each share of the capital stock having voting power
held by such stockholder.

          SECTION 2.8  PROXIES.  Each stockholder entitled to vote at a meeting
of stockholders may authorize in writing another person or persons to act for
such holder by proxy, but no proxy shall be voted or acted upon after three
years from its date, unless the person executing the proxy specifies therein
the period of time for which it is to continue in force.  A duly executed proxy
shall be irrevocable if it states that it is irrevocable and if, and only as
long as, it is coupled with an interest sufficient in law to support an
irrevocable power.  A stockholder may revoke any proxy which is not irrevocable
by attending the meeting and voting in person or by filing an instrument in
writing revoking the proxy or another duly executed proxy bearing a later date
with the Secretary of the Corporation.

          SECTION 2.9  INSPECTORS OF ELECTION.  The Corporation shall, in
advance of any meeting of stockholders, appoint one or more inspectors to act
at the meeting and make a written report thereof.  The Corporation or the
Chairman of the meeting shall appoint one or more alternate inspectors to
replace any inspector who fails to act.  Each inspector, before undertaking his
or her duties, shall take and sign an oath faithfully to execute the duties of
inspector with strict impartiality and according to the best of his or her
ability.  The inspectors shall ascertain the number of shares outstanding and
the voting power of each, determine the shares represented at the meeting and
the validity of the proxies and ballots, count all votes and ballots, determine
and retain for a reasonable period a record of the disposition of any
challenges made to any determination by the inspectors and certify their
determination of the number of shares represented at the meeting and their
count of all votes and ballots.  Each inspector shall perform his or her duties
and shall make all determinations in accordance with the Delaware General
Corporation Law including, without limitation, Section 231 of the Delaware
General Corporation Law.

          The date and time of the opening and closing of the polls for each
matter upon which the stockholders will vote at a meeting shall be announced at
the meeting.  No ballot, proxies or votes, nor revocations thereof or changes
thereto, shall be accepted by the inspectors after the closing of the polls
unless the Court of Chancery upon application by a stockholder shall determine
otherwise.

          The appointment of inspectors of election shall be in the discretion
of the Board except that as long as the Corporation has a class of voting stock
that is (i) listed on a national securities exchange, (ii) authorized for
quotation on an interdealer quotation system of a registered national
securities association, or (iii) held of record by more than 2,000
stockholders, appointment of inspectors shall be obligatory.

of three (3) years.  Each director shall hold office until his successor is
elected and qualified or until his earlier resignation.  No decrease in the
number of directors shall shorten the term of any incumbent director.

          SECTION 3.3  VACANCIES AND NEWLY CREATED DIRECTORSHIPS.  Subject to
Section 3.14 for as long as such Section remains in effect, any vacancy on the

meetings shall be held at the time and place designated by the person or
persons calling the meeting.  Notice of the time, place and purpose of any such

          SECTION 3.9  QUORUM.  At all meetings of the Board, the vote of a
majority of the whole Board shall be necessary to constitute the act of the
Board, regardless of the number of directors present at the meeting at which
such matter is voted upon.  For all purposes hereof, the phrase "whole Board"
and phrase "total number of directors" shall mean the total number of directors
that the Corporation would have if there were no vacancies.  Any meeting of the
Board may be adjourned to meet again at a stated day and hour.  Even though a
quorum is not present, as required in this Section, a majority of the directors
present at any meeting of the Board, either regular or special, may adjourn
from time to time until a quorum is present.  Notice of any adjourned meeting
need not be given.

          SECTION 3.10  FEES AND COMPENSATION.  Each director and each member
of a committee of the Board shall receive such fees and reimbursement of
expenses incurred on behalf of the Corporation or in attending meetings as the

compensation therefor.

merger pursuant to Section 253 of the Delaware General Corporation Law.  Each
committee shall have such name as may be determined from time to time by
resolution adopted by the Board.  Each committee shall keep minutes of its
meetings and report to the Board when required.

          SECTION 3.13  ACTION WITHOUT MEETINGS.  Unless otherwise restricted
by applicable law or by the Certificate of Incorporation or by these Bylaws,

books belonging to the Corporation and shall deposit all monies and other
valuable effects in the name and to the credit of the Corporation in such
depositories as may be designated by the Board.  Subject to the powers of the
Chief Financial Officer, the Treasurer may disburse the funds of the
Corporation as may be ordered by the Board, taking proper vouchers for such
disbursements, and shall render to the Board at its regular meetings, or when
the Board so requires, an account of the transactions and of the financial
condition of the Corporation.  The Treasurer shall perform such other duties
and have such other powers as the Board may from time to time prescribe.

          If required by the Board and at the expense of the Corporation, the
Chief Financial Officer, the Treasurer, and the Assistant Treasurer, if any,
shall give the Corporation a bond (which shall be renewed at such times as
specified by the Board) in such sum and with such surety or sureties as shall
be satisfactory to the Board for the faithful performance of the duties of such
person's office and for the restoration to the Corporation, in case of such
person's death, resignation retirement or removal from office, of all books,
papers, vouchers, money and other property of whatever kind in such person's
possession or under such person's control belonging to the Corporation.

          SECTION 4.9  ASSISTANT OFFICERS.  An assistant officer shall, in the
absence of the officer to whom such person is an assistant officer or in the
event of such officer's inability or refusal to act, perform the duties of such

the restrictions upon such officer.  An assistant officer shall perform such
other duties and have such other powers as the Board or the officer appointing
any such assistant officer may from time to time prescribe.

                                   ARTICLE V
                                      SEAL

          It shall not be necessary to the validity of any instrument executed
by any authorized officer or officers of the Corporation that the execution of
such instrument be evidenced by the corporate seal, and all documents,
instruments, contracts and writings of all kinds signed on behalf of the
Corporation by any authorized officer or officers shall be as effectual and
binding on the Corporation without the corporate seal, as if the execution of
the same had been evidenced by affixing the corporate seal thereto.  The Board
may give general authority to any officer to affix the seal of the Corporation
and to attest the affixing by signature.


                                   ARTICLE VI
                           FORM OF STOCK CERTIFICATE

          Every holder of stock in the Corporation shall be entitled to have a
certificate signed by, or in the name of, the Corporation by the Chairman or
Vice Chairman of the Board, if any, or by the President/CEO or a Vice
President, and by the Treasurer or Chief Financial Officer, or the Secretary or
an Assistant Secretary certifying the number of shares owned the Corporation.
Any or all of the signatures on the certificate may be a facsimile signature.
If any officer, transfer agent or registrar who has signed or whose facsimile
signature has been placed upon a certificate shall have ceased to be such
officer, transfer agent or registrar before such certificate is issued, it may
be issued by the Corporation with the same effect as if such person were such
officer, transfer agent or registrar at the date of the issuance.

          If the Corporation shall be authorized to issue more than one class
of stock or more than one series of any class, the powers, designations,
preferences and relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences or rights shall be set forth in full or
summarized on the face or back of the certificate that the Corporation shall
issue to represent such class or series of stock.  Except as otherwise provided
in Section 202 of the Delaware General Corporation Law, in lieu of the
foregoing requirements, there may be set forth on the face or back of the
certificate a statement that the Corporation will furnish without charge to
each stockholder who so requests the powers, designations, preferences and
relative, participating, optional or other special rights of each class of
stock or series thereof and the qualifications, limitations or restrictions of
such preferences or rights.


                                  ARTICLE VII
                 REPRESENTATION OF SHARES OF OTHER CORPORATION

          Any and all shares of any other corporation or corporations standing
in the name of the Corporation shall be voted, and all rights incident thereto
shall be represented and exercised on behalf of the Corporation by the Board,
Chairman or President/CEO.  The





                                       12
<PAGE>   98

foregoing authority may be exercised either by the President/CEO in person or
by any other person authorized so to do by proxy or power of attorney duly
executed by said office.


                                  ARTICLE VIII
                               TRANSFERS OF STOCK

          Upon surrender of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment or authority to
transfer, it shall be the duty of the Corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate and record the
transaction upon its books.


                                   ARTICLE IX
                     LOST, STOLEN OR DESTROYED CERTIFICATES

          The Board may direct a new certificate or certificates be issued in
place of any certificate theretofore issued alleged to have been lost, stolen
or destroyed, upon the making of an affidavit of the fact by the person
claiming the certificate to be lost, stolen or destroyed.  When authorizing
such issue of a new certificate, the Board may, in its discretion and as a
condition precedent to the issuance, require the owner of such certificate or
certificates, or such person's legal representative, to give the Corporation a
bond in such sum as it may direct as indemnity against any claim that may be
made against the Corporation with respect to the lost, stolen or destroyed
certificate.


                                   ARTICLE X
                                  RECORD DATE

          The Board may fix in advance a date, which shall not be more than
sixty (60) days nor less than ten (10) days preceding the date of any meeting
of stockholders, nor more than sixty (60) days prior to any other action, as a
record date for the determination of stockholders entitled to notice of or to
vote at any such meeting and any adjournment thereof, or to express consent to
corporate action in writing without a meeting, or entitled to receive payment
of any dividend or other distribution or allotment of any rights, or entitled
to exercise the rights in respect of any change, conversion or exchange of
stock, and in such case such stockholders, and only such stockholders as shall
be stockholders of record on the date so fixed shall be entitled to such notice
of, and to vote at, such meeting and any adjournment thereof, or to receive
payment of such dividend, or to receive such allotment of rights, or to
exercise such rights, or to give such consent, as the case may be,
notwithstanding any transfer of any stock on the books of the Corporation after
any such record date fixed as aforesaid.

                                   ARTICLE XI
                            REGISTERED STOCKHOLDERS

          The Corporation shall be entitled to treat the holder of record of
any share or shares of stock of the Corporation as the holder in fact thereof
and shall not be bound to recognize any equitable or other claim to or interest
in such share on the part of any other person, whether or not it shall have
express or other notice thereof, except as expressly provided by applicable
law.


                                  ARTICLE XII
                                  FISCAL YEAR

          The fiscal year of the Corporation shall be fixed by resolution of
the Board.


                                  ARTICLE XIII
                                   AMENDMENTS

          Subject to any contrary or limiting provisions contained in the
Certificate of Incorporation, these Bylaws may be amended or repealed, or new
Bylaws may be adopted (a) by the affirmative vote of the holders of at least a
majority of the Common Stock of the Corporation, or (b) by the affirmative vote
of the majority of the whole Board at any regular or special meeting.  Any
Bylaws adopted or amended by the stockholders may be amended or repealed by the
Board or the stockholders.


                                  ARTICLE XIV
                                   DIVIDENDS

          SECTION 14.1  DECLARATION.  Dividends on the capital stock of the
Corporation, subject to the provisions of the Certificate of Incorporation, if
any, may be declared by the Board at any regular or special meeting, pursuant
to law, and may be paid in cash, in property or in shares of capital stock.

          SECTION 14.2  SET ASIDE FUNDS.  Before payment of any dividend, there
may be set aside out of any funds of the Corporation available for dividends
such sums as the directors from time to time, in their absolute discretion,
think proper as a reserve or reserves to meet contingencies, or for equalizing
dividends, or for repairing or maintaining any property of the Corporation, or
for such other purpose as the directors shall determine to be in the best
interest of the Corporation, and the directors may modify or abolish any such
reserve in the manner in which it was created.

                                   ARTICLE XV
                         INDEMNIFICATION AND INSURANCE

          SECTION 15.1  RIGHT TO INDEMNIFICATION.  Each person who was or is a
party or is threatened to be made a party to or is involved in any action, suit
or proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she, or a person
of whom he or she is the legal representative, is or was a director or officer
of the Corporation or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, including service with
respect to employee benefit plans, whether the basis of such proceeding is
alleged action or inaction in an official capacity or in any other capacity
while serving as a director, officer, employee or agent, shall be indemnified
and held harmless by the Corporation to the fullest extent permitted by the
laws of the State of Delaware, as the same exist or may hereafter be amended,
against all costs, charges, expenses, liabilities and losses (including
attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts
paid or to be paid in settlement) reasonably incurred or suffered by such
person in connection therewith, and such indemnification shall continue as to a
person who has ceased to be a director, officer, employee or agent and shall
inure to the benefit of his or her heirs, executors and administrators;
provided, however, that the Corporation shall indemnify any such person seeking
indemnification in connection with a proceeding (or part thereof) initiated by
such person only if such proceeding (or part thereof) was authorized by the
Board.  The right to indemnification conferred in this Article shall be a
contract right and shall include the right to be paid by the Corporation the
expense incurred in defending any such proceeding in advance of its final
disposition; provided, however, that, if the Delaware General Corporation Law
requires, the payment of such expenses incurred by a director or officer in his
or her capacity as a director or officer (and not in any other capacity in
which service was or is rendered by such person while a director or officer,
including, without limitation, service to an employee benefit plan) in advance
of the final disposition of a proceeding, shall be made only upon delivery to
the Corporation of an undertaking, by or on behalf of such director or officer,
to repay all amounts so advanced if it shall ultimately be determined that such
director or officer is not entitled to be indemnified under this Section or
otherwise.  The Corporation may, by action of the Board, provide
indemnification to employees and agents of the Corporation with the same scope
and effect as the foregoing indemnification of directors and officers.

          SECTION 15.2  RIGHT OF CLAIMANT TO BRING SUIT.  If a claim under
Section 15.1 is not paid in full by the Corporation within thirty (30) days
after a written claim has been received by the Corporation, the claimant may at
any time thereafter bring suit against the Corporation to recover the unpaid
amount of the claim and, if successful in whole or in part, the claimant shall
be entitled to be paid also the expense of prosecuting such claim.  It shall be
a defense to any such action (other than an action brought to enforce a claim
for expenses incurred in defending any proceeding in advance of its final
disposition where the required undertaking, if any is required, has been
tendered to the Corporation) that the claimant has failed to meet a standard of
conduct which makes it permissible under Delaware law for the





                                       15
<PAGE>   101

Corporation to indemnify the claimant for the amount claimed.  Neither the
failure of the Corporation (including its Board, independent legal counsel, or
its stockholders) to have made a determination prior to the commencement of
such action that indemnification of the claimant is permissible in the
circumstances because he or she has met such standard of conduct, nor an actual
determination by the Corporation (including its Board, independent legal
counsel, or its stockholders) that the claimant has not met such standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has failed to meet such standard of conduct.

          SECTION 15.3  NON-EXCLUSIVITY OF RIGHTS.  The right to
indemnification and the payment of expenses incurred in defending a proceeding
in advance of its final disposition conferred in this Article shall not be
exclusive of any other right which any person may have or hereafter acquire
under any statute, provision of the Certificate of Incorporation, bylaw,
agreement, vote of stockholders or disinterested directors or otherwise.

          SECTION 15.4  INSURANCE.  The Corporation may maintain insurance, at
its expense, to protect itself and any director, officer, employee or agent of
the Corporation or another corporation, partnership, joint venture, trust or
other enterprise against any such expense, liability or loss, whether or not
the Corporation would have the power to indemnify such person against such
expense, liability or loss under Delaware law.

          SECTION 15.5  EXPENSES AS A WITNESS.  To the extent that any
director, officer, employee or agent of the Corporation, is by reason of such
position, or a position with another entity at the request of the Corporation,
a witness in any action, suit or proceeding, he or she shall be indemnified
against all costs and expenses actually and reasonably incurred by him or her
or on his or her behalf in connection therewith.

          SECTION 15.6  INDEMNITY AGREEMENTS.  The Corporation may enter into
agreements with any director, officer, employee or agent of the Corporation
providing for indemnification to the fullest extent permitted by Delaware law.

          SECTION 15.7  SETTLEMENT OF CLAIMS.  The Corporation shall not be
liable to indemnify any director, officer, employee or agent under this Article
(a) for any amounts paid in settlement of any action or claim effected without
the Corporation's written consent, which consent shall not be unreasonably
withheld; or (b) for any judicial award if the Corporation was not given a
reasonable and timely opportunity at its expense, to participate in the defense
of such action.

          SECTION 15.8  EFFECT OF AMENDMENT.  Any amendment, repeal, or
modification of this Article shall not adversely affect any right or protection
of any director, officer, employee or agent existing at the time of such
amendment, repeal or modification.

          SECTION 15.9  SUBROGATION.  In the event of payment under this
Article, the Corporation shall be subrogated to the extent of such payment to
all of the rights of recovery





                                       16
<PAGE>   102

of the director, officer, employee or agent, who shall execute all papers
required and shall do everything that may be necessary to secure such rights,
including the execution of such documents necessary to enable the Corporation
effectively to bring suit to enforce such rights.

          SECTION 15.10  NO DUPLICATION OF PAYMENTS.  The Corporation shall not
be liable under this Article to make any payment in connection with any claim
made against the director, officer, employee or agent to the extent the
director, officer, employee or agent has otherwise actually received payment
(under any insurance policy, agreement, vote, or otherwise) of the amounts
otherwise indemnifiable hereunder.

                                  SCHEDULE 7.1

                     CONDUCT OF BUSINESS PENDING THE MERGER

A.        HD

          1.          HD intends to spin-off it's wholly-owned subsidiary,
                      Healthdyne Information Enterprises, Inc. ("HIE"), in a
                      taxable distribution to its shareholders pursuant to a
                      Registration Statement on Form S-1 filed with the
                      Securities Exchange Commission on September 1, 1995 (the
                      "HIE Spin-off").  In connection with the HIE Spin-off HD
                      will transfer its ownership interests in Healthcare
                      Communications, Inc., DataView Imaging International,
                      Inc., Clinical Assessment Support System, Inc. (in
                      process of changing its name to Integrated Healthcare
                      Solutions, Inc.), and Criterion Health Strategies, Inc.
                      to HIE.  As part of the HIE Spin-off, it may be necessary
                      for HIE to amend its Articles of Incorporation or Bylaws
                      or to split, combine or reclassify its shares of capital
                      stock.  In connection with the Spin-off, HD intends to
                      enter into the following agreements (drafts of which have
                      been provided) with HIE:

                                  Distribution Agreement
                                  Corporate Services Agreement
                                  Tax Indemnity Agreement
                                  Tax Disaffiliation Agreement
                                  Trademark License Agreement

          2.          HD is presently attempting to sell the assets associated
                      with a development project referred to as "Transvivo", an
                      in vitro dialysis medical device.

          3.          HD has been requested by National Reproductive Medical
                      Centers, Inc. to invest up to $2 million in an in vitro
                      fertilization laboratory/clinic in New York City.
                      Healthdyne will consult with Tokos' management prior to
                      committing to make any such investment and will not make
                      or commit to make any such investment without the
                      unanimous approval or consent of all of the directors of
                      Healthdyne.  Moreover, if the amount of Healthdyne's
                      investment (including, in the aggregate, all amounts paid
                      or committed to be paid or expended or reasonably
                      expected to be expended by Healthdyne or any of its
                      subsidiaries in connection with such project to which
                      Healthdyne has any reasonable exposure) exceeds $2
                      million, Healthdyne shall not proceed with such
                      investment or transaction without the prior written
                      consent of Tokos.

          4.          HD intends to continue its ongoing medical joint venture
                      repurchase program on terms substantially similar to
                      previous purchases.

          5.          The Stock Option Committee of the HD Board of Directors
                      will consider approval of the issuance of stock options
                      to newly hired or recently promoted employees at the next
                      regularly scheduled meeting of the HD Board of Directors
                      in an amount not to exceed 30,000 HD Shares.

          6.          See Schedule 7.2 regarding changes in benefit plans and 
                      agreements.


B.        TM

          1.          After the date of this Agreement, TM may invest in,
                      contribute, or otherwise pay to Adeza Biomedical
                      Corporation ("Adeza") up to $1.2 million (excluding
                      payments made in the ordinary course of business for
                      products): (i) as a development contribution to secure
                      marketing rights to a product manufactured by Adeza; (ii)
                      to purchase an equity interest in Adeza; (iii) to
                      establish a jointly owned clinical reference laboratory
                      for producing test results for the Elisa format tests; or
                      (iv) for any other legitimate business purpose that TM
                      deems appropriate (collectively, "Adeza Payments").  TM
                      will consult with HD's management prior to committing to
                      make any such Adeza Payments in excess of $100,000 and
                      will not make or commit to make any such Adeza Payments
                      in excess of $100,000 to which HD objects without the
                      unanimous approval or consent of the directors of TM.
                      Moreover, if the amount of Adeza Payments (including all
                      amounts paid or committed to be paid or expended or
                      reasonably expected to be committed by TM or any or its
                      subsidiaries in connection therewith) exceeds $1.2
                      million TM shall not without the prior written consent of
                      HD go forward with the investment or transaction which
                      would result in the Adeza Payments exceeding the $1.2
                      million limit.

          2.          TM intends to purchase the following managed care
                      companies for a total aggregate amount of approximately
                      $788,258.00.

                                  WHC - WACO


          3.          TM intends to purchase $5,000,000 of additional Directors
                      & Officers Insurance to bring its total coverage to
                      $10,000,000.

          4.          Subject to Board approval, TM intends to accept from
                      Craig Davenport such number of shares of common stock of
                      TM that Mr. Davenport currently owns that may be
                      necessary to extinguish Mr. Davenport's outstanding loan
                      with the Company, which loan amount with interest is
                      approximately $250,000.

          5.          In the event that court approval of the settlement of the
                      matter entitled In re Tokos Medical Corporation
                      Securities Litigation occurs prior to the Effective Date,
                      TM shall contribute certain amounts in cash or equity to
                      the plaintiffs, as described in the Memorandum of
                      Understanding, between the parties which is incorporated
                      herein by reference.

          6.          TM may purchase some amount of infusion pumps from Deltec
                      Corporation.

          7.          The Compensation Committee of the Board of Directors will
                      consider approval of the issuance of stock options to
                      newly hired or recently promoted employees at its

execution and delivery by TM of the Merger Agreement or any agreement,
instrument or document contemplated thereby nor the performance by TM of the
transactions contemplated thereby nor the consummation of such transactions
will (i) conflict with or result in any breach of the terms and conditions of,
or constitute a default under, (a) the Certificate of Incorporation or Bylaws
of TM, (b) insofar as is known to us, any material contract or other agreement
to which TM is a party or by which it or its assets or properties may be bound,
or (c) insofar as is known to us, any judgment, decree, award, injunction,
governmental order or other restriction or obligation to which TM is a party or

       3.     Except as set forth in the Disclosure Letter, the execution and

documents contemplated thereby, the performance by TM of its obligations

not, insofar as is known to us, require TM to obtain any consent, approval or
action of, or make any filing with or give any notice to, any judicial or
governmental or regulatory body or, insofar as is known to us, any person.

       4.     The Merger Agreement and the agreements, instruments and
documents contemplated thereby have been duly authorized, executed and

                  AMENDED AND RESTATED SEVERANCE COMPENSATION
                                      AND
                         RESTRICTIVE COVENANT AGREEMENT


         This Amended and Restated Severance Compensation and Restrictive
Covenant Agreement ("Agreement") is dated as of October 2, 1995 and is
effective as of the date provided in Section 1(a) below between Healthdyne,
Inc., a Georgia corporation (the "Company"), and J. Brent Burkey (the
"Executive").

         WHEREAS, the Company, having determined that it was appropriate to
reinforce and encourage the continued attention and dedication of members of
the Company's management, including the Executive, to their assigned duties,
entered into that Severance Compensation Agreement dated February 4, 1988, as
amended from time to time thereafter, with the Executive ("Prior Agreement");
and

         WHEREAS, the Company has determined that it desires to amend and
restate the Prior Agreement and to include, in addition to severance
provisions, certain restrictive covenants from the Executive; and

         WHEREAS, simultaneously with its execution of this Agreement, the
Company is entering into an Agreement and Plan of Merger (the "Merger
Agreement") with T&H Acquisition Company ("Newco") and Tokos Medical
Corporation (Delaware) ("TM"), pursuant to which the Company and TM will merge
with and into Newco (the "Surviving Company") (such transaction shall hereafter
be referred to as the "Merger"), and such Merger will constitute a Change in
Control within the meaning of the Prior Agreement and as defined herein; and

         WHEREAS, TM's willingness to execute the Merger Agreement is
conditioned on Executive entering into the restrictive covenants contained in
this Agreement, and the parties hereto acknowledge the reasonableness of such
covenants, given the significant value that Executive will receive, directly
and indirectly, as a result of the Merger and given the payments to be made to
Executive pursuant to this Agreement in consideration of these covenants; and

         WHEREAS, the Board of Directors of the Company has determined that it
is appropriate to reinforce and encourage the continued attention and
dedication of members of the Company's management, including the Executive, to
their assigned duties without distraction in potentially disturbing
circumstances arising from the Merger or any subsequent Change in Control; and

         WHEREAS, the severance benefits payable by the Company to Executive as
provided herein are in part intended to ensure that Executive receives
reasonable
<PAGE>   2

compensation given the specific circumstances of Executive's employment history
with the Company; and

         WHEREAS, it is intended that neither this Agreement nor the Merger
shall diminish or waive in any way the rights of the Executive under the Prior
Agreement, which, as amended by this Agreement, shall continue to be applicable
to Executive's employment by the Surviving Company after the Merger;

         NOW, THEREFORE, in consideration of their respective obligations to
one another set forth in this Agreement, and other good and valuable
consideration, the receipt, sufficiency and adequacy of which the parties
hereby acknowledge, the parties to this Agreement, intending to be legally
bound, hereby agree as follows:

         1.      Term.

                 (a)  This Agreement shall become effective immediately prior
to the Effective Time of the Merger (as defined in Section 2.2 of the Merger
Agreement), provided that the Executive is still employed by the Company at
such time.  If the Merger does not become effective on or before May 31, 1996
or the Executive is not employed by the Company at the Effective Time, then
this Agreement shall be deemed never to have been in effect, and the Prior
Agreement shall remain in effect, unamended by this Agreement.

                 (b)  This Agreement shall terminate, except to the extent that
any obligation of the Company hereunder remains unpaid as of such time, upon
the earliest of (i) three years after the Effective Time if a Change in Control
(other than the Merger) has not occurred after the Effective Time; (ii) the
Date of Termination of the Executive based on death, Disability (as defined in
Section 3(b)), Retirement (as defined in Section 3(c)) or Cause (as defined in
Section 3(d)) or by the Executive other than for Good Reason (as defined in
Section 3(e)); or (iii) three years from the date of a Change in Control (as
defined in Section 2) occurring after the Merger if the Executive's employment
with the Company has not terminated as of such time.

         2.      Change in Control.  For purposes of this Agreement, a Change
in Control shall be deemed to have occurred if (a) there shall be consummated
(i) any consolidation or merger of the Company in which the Company is not the
continuing or surviving corporation or pursuant to which shares of the
Company's common stock would be converted into cash, securities or other
property, other than a merger of the Company in which the holders of the
Company's common stock immediately prior to the merger have the same
proportionate ownership of common stock of the surviving corporation
immediately after the merger, or (ii) any sale, lease, exchange or other
transfer (in one





                                      -2-
<PAGE>   3

transaction or a series of related transactions) of all, or substantially all,
of the assets of the Company, or (b) the stockholders of the Company approve
any plan or proposal for the liquidation or dissolution of the Company, or (c)
any person (as such term is used in Sections 13(d) and 14(d)(2) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act")), shall become
the beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act)
of 30% of the Company's outstanding Common Stock, or (d) during any period of
two consecutive years, individuals who at the beginning of such period
constitute the entire Board of Directors of the Company shall cease for any
reason to constitute a majority thereof unless the election, or the nomination
for election by the Company's stockholders, of each new director was approved
by a vote of at least two-thirds of the directors then still in office who were
directors at the beginning of the period; provided, however, that, in the
absence of a majority vote of the directors specified in subsection (d) of this
Section 2 to the contrary, the sale, lease, exchange or other disposition (in
one transaction or a series of related transactions) of less than 70% of the
total fair market value of all of the assets of the Company immediately prior
to such transaction or transactions shall not be deemed to be a Change in
Control and provided further that the transaction or transactions which involve
the sale, lease, exchange or other disposition of 70% or more of the total fair
market value of all of the assets of the Company immediately prior to such
transaction or transactions shall be deemed to be a Change in Control even if
approved by the Board of Directors of the Company.

         3.      Termination Following Change in Control.

                 (a)      If the Executive is still an employee of the Company
at the Effective Time or at the time of any other Change in Control, the
Executive shall be entitled to the compensation and benefits provided in
Section 4 upon the subsequent termination of the Executive's employment with
the Company by the Executive or by the Company during the term of this
Agreement, unless such termination is as a result of (i) the Executive's death;
(ii) the Executive's Disability; (iii) the Executive's Retirement; (iv) the
Executive's termination by the Company for Cause; or (v) the Executive's
decision to terminate employment other than for Good Reason.

                 (b)      Disability.  The term "Disability" as used in this
Agreement shall mean termination of the Executive's employment by the Company
as a result of the Executive's incapacity due to physical or mental illness,
provided that the Executive shall have been absent from his duties with the
Company on a full-time basis for six consecutive months and such absence shall
have continued unabated for 30 days after Notice of Termination as described in
Section 3(f) is thereafter given to the Executive by the Company.





                                      -3-
<PAGE>   4

                 (c)      Retirement.  The term "Retirement" as used in this
Agreement shall mean termination of the Executive's employment by the Company
based on the Executive's having attained age 65 or such later retirement age as
shall have been established pursuant to a written agreement between the Company
and the Executive.  Termination of Executive's employment at a time when
Executive is eligible to receive benefits under the Company's Retirement
Benefit Award or the Company's Protective Umbrella for Lifelong Security of
Employees Program shall not constitute Retirement unless Executive shall have
attained such age.

                 (d)      Cause.  The term "Cause" for purposes of this
Agreement shall mean the Company's termination of the Executive's employment on
the basis of criminal or civil fraud on the part of the Executive involving a
material amount of funds of the Company.  Notwithstanding the foregoing, the
Executive shall not be deemed to have been terminated for Cause unless and
until there shall have been delivered to the Executive a copy of a resolution
duly adopted by the affirmative vote of not less than three-quarters of the
entire membership of the Company's Board of Directors at a meeting of the Board
called and held for such purpose (after reasonable notice to the Executive and
an opportunity for the Executive, together with the Executive's counsel, to be
heard before the Board) finding that in the good faith opinion of the Board the
Executive was guilty of conduct set forth in the first sentence of this Section
3(d) and specifying the particulars thereof in detail.  For purposes of this
Agreement only, the preparation and filing of fictitious, false or misleading
claims in connection with any federal, state or other third party medical
reimbursement program, or any other violation of any rule or regulation in
respect of any federal, state or other third party medical reimbursement
program by the Company or any subsidiary of the Company shall not be deemed to
constitute "criminal fraud" or "civil fraud".

                 (e)      Good Reason.  For purposes of this Agreement, "Good
Reason" shall mean any of the following actions taken by the Company without
the Executive's express written consent:

                          (i) The assignment to the Executive by the Company of
duties inconsistent with, or the reduction of the powers and functions
associated with, the Executive's position, duties, responsibilities and status
with the Company prior to a Change in Control, or an adverse change in the
Executive's titles or offices as in effect prior to a Change in Control, or any
removal of the Executive from or any failure to re-elect the Executive to any
of such positions, except in connection with the termination of his employment
for Disability, Retirement or Cause or as a result of the Executive's death or
by the Executive other than for Good Reason;





                                      -4-
<PAGE>   5

                          (ii) A reduction by the Company in the Executive's
base salary as in effect on the date hereof or as the same may be increased
from time to time during the term of this Agreement or the Company's failure to
increase (within 12 months of the Executive's last increase in base salary) the
Executive's base salary after a Change in Control in an amount which at least
equals, on a percentage basis, the average annual percentage increase in base
salary for all corporate officers of the Company effected in the preceding 36
months;

                          (iii) Any failure by the Company to continue in
effect any benefit plan, program or arrangement (including, without limitation,
any profit sharing plan, group annuity contract, group life insurance
supplement, or medical, dental, accident and disability plans) in which the
Executive was eligible to participate at the time of a Change in Control (or
any other plans providing the Executive with substantially similar benefits)
(hereinafter referred to as "Benefit Plans"), or the taking of any action by
the Company which would adversely affect the Executive's participation in or
materially reduce the Executive's benefits under any such Benefit Plan or
deprive the Executive of any fringe benefit enjoyed by the Executive at the
time of a Change in Control;

                          (iv) Any failure by the Company to continue in effect
any incentive plan or arrangement (including, without limitations, any bonus or
contingent bonus arrangements and credits and the right to receive performance
awards and similar incentive compensation benefits) in which the Executive is
participating at the time of a Change in Control (or any other plans or
arrangements providing him with substantially similar benefits) (hereinafter
referred to as "Incentive Plans") or the taking of any action by the Company
which would adversely affect the Executive's participation in any such
Incentive Plan or reduce the Executive's benefits under any such Incentive
Plan, expressed as a percentage of his base salary, by more than five
percentage points in any fiscal year as compared to the immediately preceding
fiscal year, or any action to reduce Executive's bonuses under any Incentive
Plan by more than 20% of the average annual bonus previously paid to Executive
with respect to the preceding three fiscal years;

                          (v) Any failure by the Company to continue in effect
any plan or arrangement to receive securities of the Company (including,
without limitation, the Company's 1981 Incentive Stock Option Plan, 1983
Incentive Stock Option Plan, 1984 Nonqualified Stock Option Plan, 1985
Nonqualified Stock Option Plan, 1991 Stock Option Plan and 1993 Stock Option
Plan, Employee Stock Purchase Plan and any other plan or arrangement to receive
and exercise stock options, stock appreciation rights, restricted stock or
grants thereof) in which the Executive is participating or has the right to
participate in prior to a Change in Control (or plans or arrangements providing
him with substantially similar benefits) (hereinafter referred to as
"Securities Plans") or the taking of any action by the Company which would
adversely affect the Executive's





                                      -5-
<PAGE>   6

participation in or materially reduce the Executive's benefits under any such
Securities Plan;

                          (vi) A relocation of the Company's principal

Executive's relocation to any place other than the location at which the
Executive performed the Executive's duties prior to a Change in Control, except
for required travel by the Executive on the Company's business to an extent
substantially consistent with the Executive's business travel obligations
immediately prior to a Change in Control;

                          (vii) Any failure by the Company to provide the
Executive with the number of paid vacation days (or compensation therefor at
termination of employment) accrued to the Executive through the date of a
Change in Control, together with any earned but unused vacation days for the
vacation year in question;

                          (viii) Any material breach by the Company of any 
provision of this Agreement;

                          (ix) Any failure by the Company to obtain the
assumption of this Agreement by any successor or assign of the Company effected
in accordance with the provisions of Section 7(a) hereof;

                          (x) Any purported termination of the Executive's
employment which is not effected pursuant to a Notice of Termination satisfying
the requirements of Section 3(f), and for purposes of this Agreement, no such
purported termination shall be effective; or

                          (xi) Any proposal or request by the Company after the
Effective Date to require that the Executive enter into a non-competition
agreement with the Company where the terms of such agreement as to its scope or
duration are greater than the terms set forth in Section 5 hereof.

                 (f)      Notice of Termination.  Any termination of the
Executive's employment by the Company for a reason specified in Section 3(b),
3(c) or 3(d) shall be communicated to the Executive by a Notice of Termination
prior to the effective date of the termination.  For purposes of this
Agreement, a "Notice of Termination" shall mean a written notice which shall
indicate whether such termination is for the reason set forth in Section 3(b),
3(c) or 3(d) and which sets forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive's
employment under the provision so indicated.  For purposes of this Agreement,
no termination of the





                                      -6-
<PAGE>   7

Executive's employment by the Company shall constitute a termination for
Disability, Retirement or Cause unless such termination is preceded by a Notice
of Termination.

                 (g)      Date of Termination.  "Date of Termination" shall
mean (a) if the Executive's employment is terminated by the Company for
Disability, 30 days after a Notice of Termination is given to the Executive
(provided that the Executive shall not have returned to the performance of the
Executive's duties on a full-time basis during such 30-day period) or (b) if
the Executive's employment is terminated by the Company or the Executive for
any other reason, the date on which the Executive's termination is effective;
provided that, if within 30 days after any Notice of Termination is given to
the Executive by the Company the Executive notifies the Company that a dispute
exists concerning the termination, the Date of Termination shall be the date
the dispute is finally determined whether by mutual agreement by the parties or
upon final judgment, order or decree of a court of competent jurisdiction (the
time for appeal therefrom having expired and no appeal having been perfected).

         4.      Compensation and Benefits upon Termination of Employment.

                 (a)      If the Company shall terminate the Executive's
employment after a Change in Control other than pursuant to Section 3(b), 3(c)
or 3(d) and Section 3(f), or if the Executive shall terminate his employment
for Good Reason, then the Company shall pay to the Executive, as severance
compensation and in consideration of the Executive's adherence to the terms of
Section 5 hereof, the following:

                          (1)     On the Date of Termination, the Company shall
become liable to the Executive for an amount equal to three times the
Executive's average annual compensation from the Company (as reported on Form
W-2 pursuant to applicable provisions of the Internal Revenue Code of 1986, as
amended (the "Code")) for the five years ending prior to the Date of
Termination, which amount shall be paid to the Executive in cash on or before
the fifth day following the Date of Termination.

                          (2)     For a period of three years following the
Date of Termination, the Executive and anyone entitled to claim under or
through the Executive shall be entitled to all benefits under the group
hospitalization plan, health care plan, dental care plan, life or other
insurance or death benefit plan, or other present or future similar group
employee benefit plan or program of the Company for which key executives are
eligible at the date of a Change in Control, to the same extent as if the
Executive had continued to be an employee of the Company during such period and
such benefits shall, to the extent not fully paid under any such plan or
program, be paid by the Company.





                                      -7-
<PAGE>   8

                          (3)     For a period of three years after the Date of
Termination, the Company shall allow the Executive to utilize for his business
and personal use any Company leased automobile previously furnished to him or
an equivalent type and style of automobile and shall reimburse the Executive
for the maintenance and repair costs of such automobile and extend full
insurance coverage relating to such automobile in favor of the Executive, as
additional named insured, during such three-year period.  In addition, the
Executive shall be entitled, at the Executive's sole discretion, to exercise
any option to acquire such automobile pursuant to the terms which may be
provided in the lease agreement for the automobile in question.

                 (b)      The parties hereto agree that the payments provided
in Section 4(a) hereof are reasonable compensation in light of the Executive's
services rendered to the Company and in consideration of the Executive's
adherence to the terms of Section 5 hereof.  Neither party shall contest the
payment of such benefits as constituting an "excess parachute payment" within
the meaning of Section 280G(b)(1) of the Code.  In the event that the Executive
becomes entitled to the compensation and benefits described in Section 4(a)
hereof (the "Compensation Payments") and the Company has determined, based upon
the advise of tax counsel selected by the Company's independent auditors and
acceptable to the Executive, that, as a result of such Compensation Payments
and any other benefits or payments required to be taken into account under Code
Section 280G(b)(2) ("Parachute Payments"), any of such Parachute Payments must
be reported by the Company as "excess parachute payments" and are therefore not
deductible by the Company, the Company shall pay to the Executive at the time
specified in Section 4(a) above an additional amount (the "Gross-Up Payment")
such that the net amount retained by the Executive, after deduction of any of
the tax imposed on the Executive by Section 4999 of the Code (the "Excise Tax")
and any Federal, state and local income tax and Excise Tax upon the Gross-Up
Payment, shall be equal to the Parachute Payments determined prior to the
application of this paragraph.  The value of any non-cash benefits or any
deferred payment or benefit shall be determined by the Company's independent
auditors.  For purposes of determining the amount of the Gross-Up Payment, the
Executive shall be deemed to pay Federal income taxes at the highest marginal
rate of Federal income taxation in the calendar year in which the Gross-Up
Payment is to be made and state and local income taxes at the highest marginal
rates of taxation in the state and locality of the Executive's residence on the
Date of Termination, net of the maximum reduction in Federal income taxes which
could be obtained from deduction of such state and local taxes.  In the event
that the Excise Tax payable by the Executive is subsequently determined to be
less than the amount, if any, taken into account hereunder at the time of
termination of the Executive's employment, the Executive shall repay to the
Company at the time that the amount of such reduction in Excise Tax is finally
determined the portion of the Gross-Up Payment attributable to such reduction
plus interest on the amount of such repayment at the rate provided for in
Section 1274(b)(2)(B)





                                      -8-
<PAGE>   9

of the Code ("Repayment Amount").  In the event that the Excise Tax payable by
the Executive is determined to exceed the amount, if any, taken into account
hereunder at the time of the termination of the Executive's employment
(including by reason of any payment the existence or amount of which cannot be
determined at the time of the Gross-Up Payment), the Company shall make an
additional Gross-Up Payment in respect of such excess (plus any interest and
penalty payable with respect to such excess) immediately prior to the time that
the amount of such excess is required to be paid by Executive ("Additional
Gross-up"), such that the net amount retained by the Executive, after deduction
of any Excise Tax on the Parachute Payments and any Federal, state and local
income tax and Excise Tax upon the Additional Gross-Up Payment, shall be equal
to the Parachute Payments determined prior to the application of this
paragraph.  The obligation to pay any Repayment Amount or Additional Gross-up
shall remain in effect under this Agreement for the entire period during which
the Executive remains liable for the Excise Tax, including the period during
which any applicable statute of limitation remains open.

                 (c)      The payments provided in Section 4(a) above shall be
in lieu of any other severance compensation otherwise payable to Executive
under the Company's established severance compensation policies; provided,
however, that nothing in this Agreement shall affect or impair Executive's
vested rights under any other employee benefit plan or policy of the Company.

                 (d)      Unless the Company determines that any Parachute
Payments made hereunder must be reported as "excess parachute payments" in
accordance with the third sentence of Section 4(b) above, neither party shall
file any return taking the position that the payment of such benefits
constitutes an "excess parachute payment" within the meaning of Section
280G(b)(1) of the Code.  If the Internal Revenue Service proposes an assessment
of Excise Tax against the Executive in excess of the amount, if any, taken into
account at the time specified in Section 4(a), then, if the Company notifies
Executive in writing that the Company elects to contest such assessment at its
expense, unless the Executive waives the right to an Additional Gross-Up
Payment, the Executive (i) shall in good faith cooperate with the Company in
contesting such proposed assessment; and (ii) such Executive shall not settle
such contest without the written consent of the Company.  Any such contest
shall be controlled by the Company, provided, however, that the Executive may
participate in such contest.

Control that occurs within three years after the Effective Date where the
Executive's employment with the Company has not terminated as of the effective
date of such subsequent Change in Control.

                          (v)     "Customers" shall mean actual customers,
clients, referral sources or managed care organizations or actively sought
prospective customers,  clients, referral sources or managed care organizations
of the Company (A) during the two (2) years prior to the Effective Date and (B)
during the Covenant Period.

                          (vi)    "Restricted Territory" shall mean a one
hundred fifty (150) mile radius of the currently existing Company locations
listed on Schedule A, all of which are locations from which the Company
Products are developed, produced, marketed, sold or distributed.  The Executive
agrees to sign any amendment to Schedule A proposed by the Company, which
amendment adds or deletes Company locations so that Schedule A accurately
reflects all then current Company locations from which the Company's products
or services are developed, marketed, sold or provided.

                 (b)      Limitation on Competition  Ancillary to and as a
condition precedent to the Merger, in connection with which the Executive will
receive, both directly and indirectly, significant benefits and value, and in
consideration of the Covenant Payments payable by the Company to the Executive
under this Agreement, the Executive agrees that during the Covenant Period, the
Executive will not, without the prior written consent of the Company, anywhere
within the Restricted Territory, either directly or indirectly, alone or in
conjunction with any other party, accept, enter into or take any action in
conjunction with or in furtherance of a Competitive Position (other than action
to reject an unsolicited offer of a Competitive Position).

                 (c)      Limitation on Soliciting Customers  Ancillary to and
as a condition precedent to the Merger, in connection with which the Executive
will receive, both





                                      -11-
<PAGE>   12

directly and indirectly, significant benefits and value, and in consideration
of the Covenant Payments payable by the Company to the Executive under this
Agreement, the Executive agrees that during the Covenant Period, the Executive
will not, without the prior written consent of the Company, alone or in
conjunction with any other party, solicit, divert or appropriate or attempt to
solicit, divert or appropriate on behalf of a Competing Business with which
Executive has a Competitive Position any Customer located in the Restricted
Territory (or any other Customer with which the Executive had any direct
contact on behalf of the Company) for the purpose of providing the Customer or
having the Customer provided with a Competing Product or Competing Service.

                 (d)      Limitation on Soliciting Personnel or Other Parties
Ancillary to and as a condition precedent to the Merger, in connection with
which the Executive will receive, both directly and indirectly, significant
benefits and value, and in consideration of the Covenant Payments payable by
the Company to the Executive under this Agreement, the Executive hereby agrees
that he will not, without the prior written consent of the Company, alone or in
conjunction with any other party, solicit or attempt to solicit any employee,
consultant, contractor, independent broker or other personnel of the Company to
terminate, alter or lessen that party's affiliation with the Company or to
violate the terms of any agreement or understanding between such employee,
consultant, contractor or other person and the Company.

                 (e)      Acknowledgement  The parties acknowledge and agree
that the covenants of the Executive in Subsection (b) through (d) are and shall
be treated, under law, as "ancillary to the sale of the Company's business."
The parties acknowledge and agree that the Protective Covenants are reasonable
as to time, scope and territory given the Company's need to protect its trade
secrets and confidential business information and given the substantial
payments and benefits to which the Executive is entitled in connection with the
Merger and otherwise pursuant to this Agreement.

                 (f)      Remedies  The parties acknowledge that any breach or
threatened breach of a Protective Covenant by the Executive is reasonably
likely to result in irreparable injury to the Company, and therefore, in
addition to all remedies provided at law or in equity, the Executive agrees
that the Company shall be entitled to a temporary restraining order and a
permanent injunction to prevent a breach or contemplated breach of the
Protective Covenant.  If the Company seeks an injunction, the Executive waives
any requirement that the Company post a bond or any other security.

         6.      No Obligation to Mitigate Damages; No Effect on Other 
Contractual Rights.

                 (a)      All compensation and benefits provided to the
Executive under this Agreement are in consideration of the Executive's services
rendered to the Company and of the Executive's adhering to the terms set forth
in Section 5 hereof and the Executive shall not be required to mitigate damages
or the amount of any payment provided for under this Agreement by seeking other
employment or otherwise, nor shall the amount of any payment provided for under
this Agreement be reduced by any compensation earned by the Executive as the
result of employment by another employer after the Date of Termination, or
otherwise.

                 (b)      The provisions of this Agreement, and any payment
provided for hereunder, shall not reduce any amounts otherwise payable, or in
any way diminish the Executive's existing rights, or rights which would accrue
solely as a result of the passage of time, under any Benefit Plan, Incentive
Plan or Securities Plan, employment agreement or other contract, plan or
arrangement.

         7.      Successor to the Company.

                 (a)      The Company will require any successor or assign
(whether direct or indirect, by purchase, merger, consolidation or otherwise)
to all or substantially all of the business and/or assets of the Company, by
agreement in form and substance satisfactory to the Executive, expressly,
absolutely and unconditionally to assume and agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform it if no such succession or assignment had taken place.  Any failure of
the Company to obtain such agreement prior to the effectiveness of any such
succession or assignment shall be a material breach of this Agreement and shall
entitle the Executive to terminate the Executive's employment for Good Reason.
As used in this Agreement, "Company" shall mean the Company as hereinbefore
defined and any successor or assign to its business and/or assets as aforesaid,
including without limitation, the Surviving Company in the Merger.  If at any
time during the term of this Agreement the Executive is employed by any
corporation a majority of the voting securities of which is then owned by the
Company, "Company" as used in Sections 3, 4, 12 and 14 hereof shall in addition
include such employer.  In such event, the Company agrees that it shall pay or
shall cause such employer to pay any amounts owed to the Executive pursuant to
Section 4 hereof.

                 (b)      This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal and legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees.  If the
Executive should die while any amounts





                                      -13-
<PAGE>   14

are still payable to him or her hereunder, all such amounts, unless otherwise
provided herein, shall be paid in accordance with the terms of this Agreement
to the Executive's devisee, legatee, or the designee or, if there be no such
designee, to the Executive's estate.

         8.      Notice.  For purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
registered mail, return receipt required, postage prepaid, as follows:

or such other address as either party may have furnished to the other in
writing in accordance herewith, except that notices of change of address shall
be effective only upon receipt.

         9.      Miscellaneous.  No provisions of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in writing signed by the Executive and the Company.  No waiver by
either party hereto at any time of any breach by the other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed
by such other party shall be deemed a waiver of similar or dissimilar
provisions or conditions at the same or at any prior or subsequent time.
Neither this Agreement nor the Merger shall diminish or waive in any way the
rights of Executive under the Prior Agreement, which as amended by this
Agreement, shall continue to be applicable to Executive's employment by the
Surviving Company after the Merger.  No agreements or representations, oral or
otherwise, express or implied, with respect to the subject matter hereof have
been made by either party which are not set forth expressly in this Agreement.
This Agreement shall be governed by and construed in accordance with the laws
of the State of Georgia.

         10.     Validity.  The invalidity or unenforceability of any
provisions of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, which shall remain in full force and
effect.

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

         12.     Legal Fees and Expenses.  The Company shall pay all legal
fees, expenses and damages which the Executive may incur as a result of the
Executive's instituting legal action to enforce his rights hereunder, or in the
event the Company contests the validity, enforceability or the Executive's
interpretation of, or determinations under, this Agreement.  If the Executive
is the prevailing party or recovers any damages in such legal action, the
Executive shall be entitled to receive in addition thereto pre-judgment and
post-judgment interest on the amount of such damages.

         13.     Severability, Modification.  All provisions of this Agreement
are severable from one another, and the unenforceability or invalidity of any
provision of this Agreement shall not affect the validity or enforceability of
the remaining provisions of this Agreement, but such remaining provisions shall
be interpreted and construed in such a manner as to carry out fully the
intention of the parties.  Should any judicial body interpreting this Agreement
deem any provision of this Agreement to be unreasonably broad in time,
territory, scope or otherwise, it is the intent and desire of the parties that
such judicial body, to the greatest extent possible, reduce the breadth of such
provision to the maximum legally allowable parameters rather than deeming such
provision totally unenforceable or invalid.

         14.     Confidentiality.  The Executive acknowledges that he or she
has previously entered into, and continues to be bound by the terms of, a
Confidentiality Agreement with the Company.

         15.     Agreement Not an Employment Contract.  This Agreement shall
not be deemed to constitute or be deemed ancillary to an employment contract
between the Company and the Executive, and nothing herein shall be deemed to
give the Executive the right to continue in the employ of the Company or to
eliminate the right of the Company to discharge the Executive at any time.

                  AMENDED AND RESTATED SEVERANCE COMPENSATION
                                      AND
                         RESTRICTIVE COVENANT AGREEMENT


         This Amended and Restated Severance Compensation and Restrictive
Covenant Agreement ("Agreement") is dated as of October 2, 1995 and is
effective as of the date provided in Section 1(a) below between Healthdyne,
Inc., a Georgia corporation (the "Company"), and J. Terry Dewberry (the
"Executive").

         WHEREAS, the Company, having determined that it was appropriate to
reinforce and encourage the continued attention and dedication of members of
the Company's management, including the Executive, to their assigned duties,
entered into that Severance Compensation Agreement dated February 4, 1988, as
amended from time to time thereafter, with the Executive ("Prior Agreement");
and

         WHEREAS, the Company has determined that it desires to amend and
restate the Prior Agreement and to include, in addition to severance
provisions, certain restrictive covenants from the Executive; and

         WHEREAS, simultaneously with its execution of this Agreement, the
Company is entering into an Agreement and Plan of Merger (the "Merger
Agreement") with T&H Acquisition Company ("Newco") and Tokos Medical
Corporation (Delaware) ("TM"), pursuant to which the Company and TM will merge
with and into Newco (the "Surviving Company") (such transaction shall hereafter
be referred to as the "Merger"), and such Merger will constitute a Change in
Control within the meaning of the Prior Agreement and as defined herein; and

         WHEREAS, TM's willingness to execute the Merger Agreement is
conditioned on Executive entering into the restrictive covenants contained in
this Agreement, and the parties hereto acknowledge the reasonableness of such
covenants, given the significant value that Executive will receive, directly
and indirectly, as a result of the Merger and given the payments to be made to
Executive pursuant to this Agreement in consideration of these covenants; and

         WHEREAS, the Board of Directors of the Company has determined that it
is appropriate to reinforce and encourage the continued attention and
dedication of members of the Company's management, including the Executive, to
their assigned duties without distraction in potentially disturbing
circumstances arising from the Merger or any subsequent Change in Control; and

         WHEREAS, the severance benefits payable by the Company to Executive as
provided herein are in part intended to ensure that Executive receives
reasonable
<PAGE>   2

compensation given the specific circumstances of Executive's employment history
with the Company; and

         WHEREAS, it is intended that neither this Agreement nor the Merger
shall diminish or waive in any way the rights of the Executive under the Prior
Agreement, which, as amended by this Agreement, shall continue to be applicable
to Executive's employment by the Surviving Company after the Merger;

         NOW, THEREFORE, in consideration of their respective obligations to
one another set forth in this Agreement, and other good and valuable
consideration, the receipt, sufficiency and adequacy of which the parties
hereby acknowledge, the parties to this Agreement, intending to be legally
bound, hereby agree as follows:

         1.      Term.

                 (a)  This Agreement shall become effective immediately prior
to the Effective Time of the Merger (as defined in Section 2.2 of the Merger
Agreement), provided that the Executive is still employed by the Company at
such time.  If the Merger does not become effective on or before May 31, 1996
or the Executive is not employed by the Company at the Effective Time, then
this Agreement shall be deemed never to have been in effect, and the Prior
Agreement shall remain in effect, unamended by this Agreement.

                 (b)  This Agreement shall terminate, except to the extent that
any obligation of the Company hereunder remains unpaid as of such time, upon
the earliest of (i) three years after the Effective Time if a Change in Control
(other than the Merger) has not occurred after the Effective Time; (ii) the
Date of Termination of the Executive based on death, Disability (as defined in
Section 3(b)), Retirement (as defined in Section 3(c)) or Cause (as defined in
Section 3(d)) or by the Executive other than for Good Reason (as defined in
Section 3(e)); or (iii) three years from the date of a Change in Control (as
defined in Section 2) occurring after the Merger if the Executive's employment
with the Company has not terminated as of such time.

         2.      Change in Control.  For purposes of this Agreement, a Change
in Control shall be deemed to have occurred if (a) there shall be consummated
(i) any consolidation or merger of the Company in which the Company is not the
continuing or surviving corporation or pursuant to which shares of the
Company's common stock would be converted into cash, securities or other
property, other than a merger of the Company in which the holders of the
Company's common stock immediately prior to the merger have the same
proportionate ownership of common stock of the surviving corporation
immediately after the merger, or (ii) any sale, lease, exchange or other
transfer (in one





                                      -2-
<PAGE>   3

transaction or a series of related transactions) of all, or substantially all,
of the assets of the Company, or (b) the stockholders of the Company approve
any plan or proposal for the liquidation or dissolution of the Company, or (c)
any person (as such term is used in Sections 13(d) and 14(d)(2) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act")), shall become
the beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act)
of 30% of the Company's outstanding Common Stock, or (d) during any period of
two consecutive years, individuals who at the beginning of such period
constitute the entire Board of Directors of the Company shall cease for any
reason to constitute a majority thereof unless the election, or the nomination
for election by the Company's stockholders, of each new director was approved
by a vote of at least two-thirds of the directors then still in office who were
directors at the beginning of the period; provided, however, that, in the
absence of a majority vote of the directors specified in subsection (d) of this
Section 2 to the contrary, the sale, lease, exchange or other disposition (in
one transaction or a series of related transactions) of less than 70% of the
total fair market value of all of the assets of the Company immediately prior
to such transaction or transactions shall not be deemed to be a Change in
Control and provided further that the transaction or transactions which involve
the sale, lease, exchange or other disposition of 70% or more of the total fair
market value of all of the assets of the Company immediately prior to such
transaction or transactions shall be deemed to be a Change in Control even if
approved by the Board of Directors of the Company.

         3.      Termination Following Change in Control.

                 (a)      If the Executive is still an employee of the Company
at the Effective Time or at the time of any other Change in Control, the
Executive shall be entitled to the compensation and benefits provided in
Section 4 upon the subsequent termination of the Executive's employment with
the Company by the Executive or by the Company during the term of this
Agreement, unless such termination is as a result of (i) the Executive's death;
(ii) the Executive's Disability; (iii) the Executive's Retirement; (iv) the
Executive's termination by the Company for Cause; or (v) the Executive's
decision to terminate employment other than for Good Reason.

                 (b)      Disability.  The term "Disability" as used in this
Agreement shall mean termination of the Executive's employment by the Company
as a result of the Executive's incapacity due to physical or mental illness,
provided that the Executive shall have been absent from his duties with the
Company on a full-time basis for six consecutive months and such absence shall
have continued unabated for 30 days after Notice of Termination as described in
Section 3(f) is thereafter given to the Executive by the Company.





                                      -3-
<PAGE>   4

                 (c)      Retirement.  The term "Retirement" as used in this
Agreement shall mean termination of the Executive's employment by the Company
based on the Executive's having attained age 65 or such later retirement age as
shall have been established pursuant to a written agreement between the Company
and the Executive.  Termination of Executive's employment at a time when
Executive is eligible to receive benefits under the Company's Retirement
Benefit Award or the Company's Protective Umbrella for Lifelong Security of
Employees Program shall not constitute Retirement unless Executive shall have
attained such age.

                 (d)      Cause.  The term "Cause" for purposes of this
Agreement shall mean the Company's termination of the Executive's employment on
the basis of criminal or civil fraud on the part of the Executive involving a
material amount of funds of the Company.  Notwithstanding the foregoing, the
Executive shall not be deemed to have been terminated for Cause unless and
until there shall have been delivered to the Executive a copy of a resolution
duly adopted by the affirmative vote of not less than three-quarters of the
entire membership of the Company's Board of Directors at a meeting of the Board
called and held for such purpose (after reasonable notice to the Executive and
an opportunity for the Executive, together with the Executive's counsel, to be
heard before the Board) finding that in the good faith opinion of the Board the
Executive was guilty of conduct set forth in the first sentence of this Section
3(d) and specifying the particulars thereof in detail.  For purposes of this
Agreement only, the preparation and filing of fictitious, false or misleading
claims in connection with any federal, state or other third party medical
reimbursement program, or any other violation of any rule or regulation in
respect of any federal, state or other third party medical reimbursement
program by the Company or any subsidiary of the Company shall not be deemed to
constitute "criminal fraud" or "civil fraud".

                 (e)      Good Reason.  For purposes of this Agreement, "Good
Reason" shall mean any of the following actions taken by the Company without
the Executive's express written consent:

                          (i) The assignment to the Executive by the Company of
duties inconsistent with, or the reduction of the powers and functions
associated with, the Executive's position, duties, responsibilities and status
with the Company prior to a Change in Control, or an adverse change in the
Executive's titles or offices as in effect prior to a Change in Control, or any
removal of the Executive from or any failure to re-elect the Executive to any
of such positions, except in connection with the termination of his employment
for Disability, Retirement or Cause or as a result of the Executive's death or
by the Executive other than for Good Reason;





                                      -4-
<PAGE>   5

                          (ii) A reduction by the Company in the Executive's
base salary as in effect on the date hereof or as the same may be increased
from time to time during the term of this Agreement or the Company's failure to
increase (within 12 months of the Executive's last increase in base salary) the
Executive's base salary after a Change in Control in an amount which at least
equals, on a percentage basis, the average annual percentage increase in base
salary for all corporate officers of the Company effected in the preceding 36
months;

                          (iii) Any failure by the Company to continue in
effect any benefit plan, program or arrangement (including, without limitation,
any profit sharing plan, group annuity contract, group life insurance
supplement, or medical, dental, accident and disability plans) in which the
Executive was eligible to participate at the time of a Change in Control (or
any other plans providing the Executive with substantially similar benefits)
(hereinafter referred to as "Benefit Plans"), or the taking of any action by
the Company which would adversely affect the Executive's participation in or
materially reduce the Executive's benefits under any such Benefit Plan or
deprive the Executive of any fringe benefit enjoyed by the Executive at the
time of a Change in Control;

                          (iv) Any failure by the Company to continue in effect
any incentive plan or arrangement (including, without limitations, any bonus or
contingent bonus arrangements and credits and the right to receive performance
awards and similar incentive compensation benefits) in which the Executive is
participating at the time of a Change in Control (or any other plans or
arrangements providing him with substantially similar benefits) (hereinafter
referred to as "Incentive Plans") or the taking of any action by the Company
which would adversely affect the Executive's participation in any such
Incentive Plan or reduce the Executive's benefits under any such Incentive
Plan, expressed as a percentage of his base salary, by more than five
percentage points in any fiscal year as compared to the immediately preceding
fiscal year, or any action to reduce Executive's bonuses under any Incentive
Plan by more than 20% of the average annual bonus previously paid to Executive
with respect to the preceding three fiscal years;

                          (v) Any failure by the Company to continue in effect
any plan or arrangement to receive securities of the Company (including,
without limitation, the Company's 1981 Incentive Stock Option Plan, 1983
Incentive Stock Option Plan, 1984 Nonqualified Stock Option Plan, 1985
Nonqualified Stock Option Plan, 1991 Stock Option Plan and 1993 Stock Option
Plan, Employee Stock Purchase Plan and any other plan or arrangement to receive
and exercise stock options, stock appreciation rights, restricted stock or
grants thereof) in which the Executive is participating or has the right to
participate in prior to a Change in Control (or plans or arrangements providing
him with substantially similar benefits) (hereinafter referred to as
"Securities Plans") or the taking of any action by the Company which would
adversely affect the Executive's





                                      -5-
<PAGE>   6

participation in or materially reduce the Executive's benefits under any such
Securities Plan;

                          (vi) A relocation of the Company's principal

Executive performed the Executive's duties prior to a Change in Control, except
for required travel by the Executive on the Company's business to an extent
substantially consistent with the Executive's business travel obligations
immediately prior to a Change in Control;

                          (vii) Any failure by the Company to provide the
Executive with the number of paid vacation days (or compensation therefor at
termination of employment) accrued to the Executive through the date of a
Change in Control, together with any earned but unused vacation days for the
vacation year in question;

                          (viii) Any material breach by the Company of any
provision of this Agreement;

                          (ix) Any failure by the Company to obtain the
assumption of this Agreement by any successor or assign of the Company effected

                          (x) Any purported termination of the Executive's
employment which is not effected pursuant to a Notice of Termination satisfying
the requirements of Section 3(f), and for purposes of this Agreement, no such
purported termination shall be effective; or

                          (xi) Any proposal or request by the Company after the
Effective Date to require that the Executive enter into a non-competition
agreement with the Company where the terms of such agreement as to its scope or
duration are greater than the terms set forth in Section 5 hereof.

                 (f)      Notice of Termination.  Any termination of the
Executive's employment by the Company for a reason specified in Section 3(b),
3(c) or 3(d) shall be communicated to the Executive by a Notice of Termination
prior to the effective date of the termination.  For purposes of this
Agreement, a "Notice of Termination" shall mean a written notice which shall
indicate whether such termination is for the reason set forth in Section 3(b),
3(c) or 3(d) and which sets forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive's
employment under the provision so indicated.  For purposes of this Agreement,
no termination of the





                                      -6-
<PAGE>   7

Executive's employment by the Company shall constitute a termination for
Disability, Retirement or Cause unless such termination is preceded by a Notice
of Termination.

                 (g)      Date of Termination.  "Date of Termination" shall
mean (a) if the Executive's employment is terminated by the Company for
Disability, 30 days after a Notice of Termination is given to the Executive
(provided that the Executive shall not have returned to the performance of the
Executive's duties on a full-time basis during such 30-day period) or (b) if
the Executive's employment is terminated by the Company or the Executive for
any other reason, the date on which the Executive's termination is effective;
provided that, if within 30 days after any Notice of Termination is given to
the Executive by the Company the Executive notifies the Company that a dispute
exists concerning the termination, the Date of Termination shall be the date
the dispute is finally determined whether by mutual agreement by the parties or
upon final judgment, order or decree of a court of competent jurisdiction (the
time for appeal therefrom having expired and no appeal having been perfected).

         4.      Compensation and Benefits upon Termination of Employment.

                 (a)      If the Company shall terminate the Executive's
employment after a Change in Control other than pursuant to Section 3(b), 3(c)
or 3(d) and Section 3(f), or if the Executive shall terminate his employment
for Good Reason, then the Company shall pay to the Executive, as severance
compensation and in consideration of the Executive's adherence to the terms of
Section 5 hereof, the following:

                          (1)     On the Date of Termination, the Company shall
become liable to the Executive for an amount equal to three times the
Executive's average annual compensation from the Company (as reported on Form
W-2 pursuant to applicable provisions of the Internal Revenue Code of 1986, as
amended (the "Code")) for the five years ending prior to the Date of
Termination, which amount shall be paid to the Executive in cash on or before
the fifth day following the Date of Termination.

                          (2)     For a period of three years following the
Date of Termination, the Executive and anyone entitled to claim under or
through the Executive shall be entitled to all benefits under the group
hospitalization plan, health care plan, dental care plan, life or other
insurance or death benefit plan, or other present or future similar group
employee benefit plan or program of the Company for which key executives are
eligible at the date of a Change in Control, to the same extent as if the
Executive had continued to be an employee of the Company during such period and
such benefits shall, to the extent not fully paid under any such plan or
program, be paid by the Company.





                                      -7-
<PAGE>   8

                          (3)     For a period of three years after the Date of
Termination, the Company shall allow the Executive to utilize for his business
and personal use any Company leased automobile previously furnished to him or
an equivalent type and style of automobile and shall reimburse the Executive
for the maintenance and repair costs of such automobile and extend full
insurance coverage relating to such automobile in favor of the Executive, as
additional named insured, during such three-year period.  In addition, the
Executive shall be entitled, at the Executive's sole discretion, to exercise
any option to acquire such automobile pursuant to the terms which may be
provided in the lease agreement for the automobile in question.

                 (b)      The parties hereto agree that the payments provided
in Section 4(a) hereof are reasonable compensation in light of the Executive's
services rendered to the Company and in consideration of the Executive's
adherence to the terms of Section 5 hereof.  Neither party shall contest the
payment of such benefits as constituting an "excess parachute payment" within
the meaning of Section 280G(b)(1) of the Code.  In the event that the Executive
becomes entitled to the compensation and benefits described in Section 4(a)
hereof (the "Compensation Payments") and the Company has determined, based upon
the advise of tax counsel selected by the Company's independent auditors and
acceptable to the Executive, that, as a result of such Compensation Payments
and any other benefits or payments required to be taken into account under Code
Section 280G(b)(2) ("Parachute Payments"), any of such Parachute Payments must
be reported by the Company as "excess parachute payments" and are therefore not
deductible by the Company, the Company shall pay to the Executive at the time
specified in Section 4(a) above an additional amount (the "Gross-Up Payment")
such that the net amount retained by the Executive, after deduction of any of
the tax imposed on the Executive by Section 4999 of the Code (the "Excise Tax")
and any Federal, state and local income tax and Excise Tax upon the Gross-Up
Payment, shall be equal to the Parachute Payments determined prior to the
application of this paragraph.  The value of any non-cash benefits or any
deferred payment or benefit shall be determined by the Company's independent
auditors.  For purposes of determining the amount of the Gross-Up Payment, the
Executive shall be deemed to pay Federal income taxes at the highest marginal
rate of Federal income taxation in the calendar year in which the Gross-Up
Payment is to be made and state and local income taxes at the highest marginal
rates of taxation in the state and locality of the Executive's residence on the
Date of Termination, net of the maximum reduction in Federal income taxes which
could be obtained from deduction of such state and local taxes.  In the event
that the Excise Tax payable by the Executive is subsequently determined to be
less than the amount, if any, taken into account hereunder at the time of
termination of the Executive's employment, the Executive shall repay to the
Company at the time that the amount of such reduction in Excise Tax is finally
determined the portion of the Gross-Up Payment attributable to such reduction
plus interest on the amount of such repayment at the rate provided for in
Section 1274(b)(2)(B)





                                      -8-
<PAGE>   9

of the Code ("Repayment Amount").  In the event that the Excise Tax payable by
the Executive is determined to exceed the amount, if any, taken into account
hereunder at the time of the termination of the Executive's employment
(including by reason of any payment the existence or amount of which cannot be
determined at the time of the Gross-Up Payment), the Company shall make an
additional Gross-Up Payment in respect of such excess (plus any interest and
penalty payable with respect to such excess) immediately prior to the time that
the amount of such excess is required to be paid by Executive ("Additional
Gross-up"), such that the net amount retained by the Executive, after deduction
of any Excise Tax on the Parachute Payments and any Federal, state and local
income tax and Excise Tax upon the Additional Gross-Up Payment, shall be equal
to the Parachute Payments determined prior to the application of this
paragraph.  The obligation to pay any Repayment Amount or Additional Gross-up
shall remain in effect under this Agreement for the entire period during which
the Executive remains liable for the Excise Tax, including the period during
which any applicable statute of limitation remains open.

                 (c)      The payments provided in Section 4(a) above shall be
in lieu of any other severance compensation otherwise payable to Executive
under the Company's established severance compensation policies; provided,
however, that nothing in this Agreement shall affect or impair Executive's
vested rights under any other employee benefit plan or policy of the Company.

                 (d)      Unless the Company determines that any Parachute
Payments made hereunder must be reported as "excess parachute payments" in
accordance with the third sentence of Section 4(b) above, neither party shall
file any return taking the position that the payment of such benefits
constitutes an "excess parachute payment" within the meaning of Section
280G(b)(1) of the Code.  If the Internal Revenue Service proposes an assessment
of Excise Tax against the Executive in excess of the amount, if any, taken into
account at the time specified in Section 4(a), then, if the Company notifies
Executive in writing that the Company elects to contest such assessment at its
expense, unless the Executive waives the right to an Additional Gross-Up
Payment, the Executive (i) shall in good faith cooperate with the Company in
contesting such proposed assessment; and (ii) such Executive shall not settle
such contest without the written consent of the Company.  Any such contest
shall be controlled by the Company, provided, however, that the Executive may
participate in such contest.

         (a)     Definitions

                 This Subsection sets forth the definition of certain

                          (i)     "Competing Business" shall mean a business
(other than the Company) that, directly or through a controlled subsidiary or
through an affiliate, (a) develops, markets and/or sells products for uterine

business, or a division of that business, derived more than twenty percent
(20%) of its gross revenues or more than $2,000,000 in gross revenues from the
development, marketing or sale of Competing Products and/or the provision of
Competing Services; provided, however, that neither Healthdyne Technologies,
Inc., a Georgia corporation and the manufacturer of medical devices utilized by
the Company ("HTI"), nor Healthdyne Information Enterprises, Inc., a Georgia
corporation engaged in healthcare information services ("HIE"), shall
constitute a Competing Business unless it provides patient care services to
obstetrical patients in the home.

                          (ii)    "Competitive Position" shall mean: (A) the
Executive's direct or indirect equity ownership (excluding ownership of less
than one percent (1%) of the outstanding common stock of any publicly held
corporation) or control of any portion of any Competing Business; or (B) any
employment, consulting, partnership, advisory, directorship, agency,
promotional or independent contractor arrangement between the Executive and any
Competing Business where the Executive performs services for the Competing
Business substantially similar to those the Executive performed for the
Company, provided, however that Executive shall not be deemed to have a
Competitive Position solely because of (y) Executive's position as a director
or holder of more than one percent (1%) of the outstanding stock of HTI or HIE,
if Executive had such position at the Effective Time or (z) Executive's
services for a Competing Business that are not directly related to the sale of
Competing Products or the provision of Competing Services, unless more than
thirty-five percent (35%) of the gross revenues of the





                                      -10-
<PAGE>   11

later of (A) the Effective Date or (B) the effective date of any Change in
Control that occurs within three years after the Effective Date where the
Executive's employment with the Company has not terminated as of the effective
date of such subsequent Change in Control.

                          (v)     "Customers" shall mean actual customers,
clients, referral sources or managed care organizations or actively sought
prospective customers,  clients, referral sources or managed care organizations
of the Company (A) during the two (2) years prior to the Effective Date and (B)
during the Covenant Period.

                          (vi)    "Restricted Territory" shall mean a one
hundred fifty (150) mile radius of the currently existing Company locations
listed on Schedule A, all of which are locations from which the Company
Products are developed, produced, marketed, sold or distributed.  The Executive
agrees to sign any amendment to Schedule A proposed by the Company, which
amendment adds or deletes Company locations so that Schedule A accurately
reflects all then current Company locations from which the Company's products
or services are developed, marketed, sold or provided.

                 (b)      Limitation on Competition  Ancillary to and as a
condition precedent to the Merger, in connection with which the Executive will
receive, both directly and indirectly, significant benefits and value, and in
consideration of the Covenant Payments payable by the Company to the Executive
under this Agreement, the Executive agrees that during the Covenant Period, the
Executive will not, without the prior written consent of the Company, anywhere
within the Restricted Territory, either directly or indirectly, alone or in
conjunction with any other party, accept, enter into or take any action in
conjunction with or in furtherance of a Competitive Position (other than action
to reject an unsolicited offer of a Competitive Position).

                 (c)      Limitation on Soliciting Customers  Ancillary to and
as a condition precedent to the Merger, in connection with which the Executive
will receive, both directly and indirectly, significant benefits and value, and
in consideration of the





                                      -11-
<PAGE>   12

Covenant Payments payable by the Company to the Executive under this Agreement,
the Executive agrees that during the Covenant Period, the Executive will not,
without the prior written consent of the Company, alone or in conjunction with
any other party, solicit, divert or appropriate or attempt to solicit, divert
or appropriate on behalf of a Competing Business with which Executive has a
Competitive Position any Customer located in the Restricted Territory (or any
other Customer with which the Executive had any direct contact on behalf of the
Company) for the purpose of providing the Customer or having the Customer
provided with a Competing Product or Competing Service.

                 (d)      Limitation on Soliciting Personnel or Other Parties
Ancillary to and as a condition precedent to the Merger, in connection with
which the Executive will receive, both directly and indirectly, significant
benefits and value, and in consideration of the Covenant Payments payable by
the Company to the Executive under this Agreement, the Executive hereby agrees
that he will not, without the prior written consent of the Company, alone or in
conjunction with any other party, solicit or attempt to solicit any employee,
consultant, contractor, independent broker or other personnel of the Company to
terminate, alter or lessen that party's affiliation with the Company or to
violate the terms of any agreement or understanding between such employee,
consultant, contractor or other person and the Company.

                 (e)      Acknowledgement  The parties acknowledge and agree
that the covenants of the Executive in Subsection (b) through (d) are and shall
be treated, under law, as "ancillary to the sale of the Company's business."
The parties acknowledge and agree that the Protective Covenants are reasonable
as to time, scope and territory given the Company's need to protect its trade
secrets and confidential business information and given the substantial
payments and benefits to which the Executive is entitled in connection with the
Merger and otherwise pursuant to this Agreement.

                 (f)      Remedies  The parties acknowledge that any breach or
threatened breach of a Protective Covenant by the Executive is reasonably
likely to result in irreparable injury to the Company, and therefore, in
addition to all remedies provided at law or in equity, the Executive agrees
that the Company shall be entitled to a temporary restraining order and a
permanent injunction to prevent a breach or contemplated breach of the
Protective Covenant.  If the Company seeks an injunction, the Executive waives
any requirement that the Company post a bond or any other security.

         6.      No Obligation to Mitigate Damages; No Effect on Other 
Contractual Rights.

                 (a)      All compensation and benefits provided to the
Executive under this Agreement are in consideration of the Executive's services
rendered to the Company and





                                      -12-
<PAGE>   13

of the Executive's adhering to the terms set forth in Section 5 hereof and the
Executive shall not be required to mitigate damages or the amount of any
payment provided for under this Agreement by seeking other employment or
otherwise, nor shall the amount of any payment provided for under this
Agreement be reduced by any compensation earned by the Executive as the result
of employment by another employer after the Date of Termination, or otherwise.

                 (b)      The provisions of this Agreement, and any payment
provided for hereunder, shall not reduce any amounts otherwise payable, or in
any way diminish the Executive's existing rights, or rights which would accrue
solely as a result of the passage of time, under any Benefit Plan, Incentive
Plan or Securities Plan, employment agreement or other contract, plan or
arrangement.

         7.      Successor to the Company.

                 (a)      The Company will require any successor or assign
(whether direct or indirect, by purchase, merger, consolidation or otherwise)
to all or substantially all of the business and/or assets of the Company, by
agreement in form and substance satisfactory to the Executive, expressly,
absolutely and unconditionally to assume and agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform it if no such succession or assignment had taken place.  Any failure of
the Company to obtain such agreement prior to the effectiveness of any such
succession or assignment shall be a material breach of this Agreement and shall
entitle the Executive to terminate the Executive's employment for Good Reason.
As used in this Agreement, "Company" shall mean the Company as hereinbefore
defined and any successor or assign to its business and/or assets as aforesaid,
including without limitation, the Surviving Company in the Merger.  If at any
time during the term of this Agreement the Executive is employed by any
corporation a majority of the voting securities of which is then owned by the
Company, "Company" as used in Sections 3, 4, 12 and 14 hereof shall in addition
include such employer.  In such event, the Company agrees that it shall pay or
shall cause such employer to pay any amounts owed to the Executive pursuant to
Section 4 hereof.

                 (b)      This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal and legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees.  If the
Executive should die while any amounts are still payable to him or her
hereunder, all such amounts, unless otherwise provided herein, shall be paid in
accordance with the terms of this Agreement to the Executive's devisee,
legatee, or the designee or, if there be no such designee, to the Executive's
estate.

                          Marietta, Georgia  30062

or such other address as either party may have furnished to the other in
writing in accordance herewith, except that notices of change of address shall
be effective only upon receipt.

         9.      Miscellaneous.  No provisions of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in writing signed by the Executive and the Company.  No waiver by
either party hereto at any time of any breach by the other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed
by such other party shall be deemed a waiver of similar or dissimilar
provisions or conditions at the same or at any prior or subsequent time.
Neither this Agreement nor the Merger shall diminish or waive in any way the
rights of Executive under the Prior Agreement, which as amended by this
Agreement, shall continue to be applicable to Executive's employment by the
Surviving Company after the Merger.  No agreements or representations, oral or
otherwise, express or implied, with respect to the subject matter hereof have
been made by either party which are not set forth expressly in this Agreement.
This Agreement shall be governed by and construed in accordance with the laws
of the State of Georgia.

         10.     Validity.  The invalidity or unenforceability of any
provisions of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, which shall remain in full force and
effect.

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

         12.     Legal Fees and Expenses.  The Company shall pay all legal
fees, expenses and damages which the Executive may incur as a result of the
Executive's instituting legal action to enforce his rights hereunder, or in the
event the Company contests the validity, enforceability or the Executive's
interpretation of, or determinations under, this Agreement.  If the Executive
is the prevailing party or recovers any damages in such legal action, the
Executive shall be entitled to receive in addition thereto pre-judgment and
post-judgment interest on the amount of such damages.

         13.     Severability, Modification.  All provisions of this Agreement
are severable from one another, and the unenforceability or invalidity of any
provision of this Agreement shall not affect the validity or enforceability of
the remaining provisions of this Agreement, but such remaining provisions shall
be interpreted and construed in such a manner as to carry out fully the
intention of the parties.  Should any judicial body interpreting this Agreement
deem any provision of this Agreement to be unreasonably broad in time,
territory, scope or otherwise, it is the intent and desire of the parties that
such judicial body, to the greatest extent possible, reduce the breadth of such
provision to the maximum legally allowable parameters rather than deeming such
provision totally unenforceable or invalid.

         14.     Confidentiality.  The Executive acknowledges that he or she
has previously entered into, and continues to be bound by the terms of, a
Confidentiality Agreement with the Company.

         15.     Agreement Not an Employment Contract.  This Agreement shall
not be deemed to constitute or be deemed ancillary to an employment contract
between the Company and the Executive, and nothing herein shall be deemed to
give the Executive the right to continue in the employ of the Company or to
eliminate the right of the Company to discharge the Executive at any time.

                  AMENDED AND RESTATED SEVERANCE COMPENSATION
                                      AND
                         RESTRICTIVE COVENANT AGREEMENT


         This Amended and Restated Severance Compensation and Restrictive
Covenant Agreement ("Agreement") is dated as of October 2, 1995 and is
effective as of the date provided in Section 1(a) below between Healthdyne,
Inc., a Georgia corporation (the "Company"), and Donald R. Millard (the
"Executive").

         WHEREAS, the Company, having determined that it was appropriate to
reinforce and encourage the continued attention and dedication of members of
the Company's management, including the Executive, to their assigned duties,
entered into that Severance Compensation Agreement dated February 4, 1988, as
amended from time to time thereafter, with the Executive ("Prior Agreement");
and

         WHEREAS, the Company has determined that it desires to amend and
restate the Prior Agreement and to include, in addition to severance
provisions, certain restrictive covenants from the Executive; and

         WHEREAS, simultaneously with its execution of this Agreement, the
Company is entering into an Agreement and Plan of Merger (the "Merger
Agreement") with T&H Acquisition Company ("Newco") and Tokos Medical
Corporation (Delaware) ("TM"), pursuant to which the Company and TM will merge
with and into Newco (the "Surviving Company") (such transaction shall hereafter
be referred to as the "Merger"), and such Merger will constitute a Change in
Control within the meaning of the Prior Agreement and as defined herein; and

         WHEREAS, TM's willingness to execute the Merger Agreement is
conditioned on Executive entering into the restrictive covenants contained in
this Agreement, and the parties hereto acknowledge the reasonableness of such
covenants, given the significant value that Executive will receive, directly
and indirectly, as a result of the Merger and given the payments to be made to
Executive pursuant to this Agreement in consideration of these covenants; and

         WHEREAS, the Board of Directors of the Company has determined that it
is appropriate to reinforce and encourage the continued attention and
dedication of members of the Company's management, including the Executive, to
their assigned duties without distraction in potentially disturbing
circumstances arising from the Merger or any subsequent Change in Control; and

         WHEREAS, the severance benefits payable by the Company to Executive as
provided herein are in part intended to ensure that Executive receives
reasonable
<PAGE>   2

compensation given the specific circumstances of Executive's employment history
with the Company; and

         WHEREAS, it is intended that neither this Agreement nor the Merger
shall diminish or waive in any way the rights of the Executive under the Prior
Agreement, which, as amended by this Agreement, shall continue to be applicable
to Executive's employment by the Surviving Company after the Merger;

         NOW, THEREFORE, in consideration of their respective obligations to
one another set forth in this Agreement, and other good and valuable
consideration, the receipt, sufficiency and adequacy of which the parties
hereby acknowledge, the parties to this Agreement, intending to be legally
bound, hereby agree as follows:

         1.      Term.

                 (a)  This Agreement shall become effective immediately prior
to the Effective Time of the Merger (as defined in Section 2.2 of the Merger
Agreement), provided that the Executive is still employed by the Company at
such time.  If the Merger does not become effective on or before May 31, 1996
or the Executive is not employed by the Company at the Effective Time, then
this Agreement shall be deemed never to have been in effect, and the Prior
Agreement shall remain in effect, unamended by this Agreement.

                 (b)  This Agreement shall terminate, except to the extent that
any obligation of the Company hereunder remains unpaid as of such time, upon
the earliest of (i) three years after the Effective Time if a Change in Control
(other than the Merger) has not occurred after the Effective Time; (ii) the
Date of Termination of the Executive based on death, Disability (as defined in
Section 3(b)), Retirement (as defined in Section 3(c)) or Cause (as defined in
Section 3(d)) or by the Executive other than for Good Reason (as defined in
Section 3(e)); or (iii) three years from the date of a Change in Control (as
defined in Section 2) occurring after the Merger if the Executive's employment
with the Company has not terminated as of such time.

         2.      Change in Control.  For purposes of this Agreement, a Change
in Control shall be deemed to have occurred if (a) there shall be consummated
(i) any consolidation or merger of the Company in which the Company is not the
continuing or surviving corporation or pursuant to which shares of the
Company's common stock would be converted into cash, securities or other
property, other than a merger of the Company in which the holders of the
Company's common stock immediately prior to the merger have the same
proportionate ownership of common stock of the surviving corporation
immediately after the merger, or (ii) any sale, lease, exchange or other
transfer (in one





                                      -2-
<PAGE>   3

transaction or a series of related transactions) of all, or substantially all,
of the assets of the Company, or (b) the stockholders of the Company approve
any plan or proposal for the liquidation or dissolution of the Company, or (c)
any person (as such term is used in Sections 13(d) and 14(d)(2) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act")), shall become
the beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act)
of 30% of the Company's outstanding Common Stock, or (d) during any period of
two consecutive years, individuals who at the beginning of such period
constitute the entire Board of Directors of the Company shall cease for any
reason to constitute a majority thereof unless the election, or the nomination
for election by the Company's stockholders, of each new director was approved
by a vote of at least two-thirds of the directors then still in office who were
directors at the beginning of the period; provided, however, that, in the
absence of a majority vote of the directors specified in subsection (d) of this
Section 2 to the contrary, the sale, lease, exchange or other disposition (in
one transaction or a series of related transactions) of less than 70% of the
total fair market value of all of the assets of the Company immediately prior
to such transaction or transactions shall not be deemed to be a Change in
Control and provided further that the transaction or transactions which involve
the sale, lease, exchange or other disposition of 70% or more of the total fair
market value of all of the assets of the Company immediately prior to such
transaction or transactions shall be deemed to be a Change in Control even if
approved by the Board of Directors of the Company.

         3.      Termination Following Change in Control.

                 (a)      If the Executive is still an employee of the Company
at the Effective Time or at the time of any other Change in Control, the
Executive shall be entitled to the compensation and benefits provided in
Section 4 upon the subsequent termination of the Executive's employment with
the Company by the Executive or by the Company during the term of this
Agreement, unless such termination is as a result of (i) the Executive's death;
(ii) the Executive's Disability; (iii) the Executive's Retirement; (iv) the
Executive's termination by the Company for Cause; or (v) the Executive's
decision to terminate employment other than for Good Reason.

                 (b)      Disability.  The term "Disability" as used in this
Agreement shall mean termination of the Executive's employment by the Company
as a result of the Executive's incapacity due to physical or mental illness,
provided that the Executive shall have been absent from his duties with the
Company on a full-time basis for six consecutive months and such absence shall
have continued unabated for 30 days after Notice of Termination as described in
Section 3(f) is thereafter given to the Executive by the Company.





                                      -3-
<PAGE>   4

                 (c)      Retirement.  The term "Retirement" as used in this
Agreement shall mean termination of the Executive's employment by the Company
based on the Executive's having attained age 65 or such later retirement age as
shall have been established pursuant to a written agreement between the Company
and the Executive.  Termination of Executive's employment at a time when
Executive is eligible to receive benefits under the Company's Retirement
Benefit Award or the Company's Protective Umbrella for Lifelong Security of
Employees Program shall not constitute Retirement unless Executive shall have
attained such age.

                 (d)      Cause.  The term "Cause" for purposes of this
Agreement shall mean the Company's termination of the Executive's employment on
the basis of criminal or civil fraud on the part of the Executive involving a
material amount of funds of the Company.  Notwithstanding the foregoing, the
Executive shall not be deemed to have been terminated for Cause unless and
until there shall have been delivered to the Executive a copy of a resolution
duly adopted by the affirmative vote of not less than three-quarters of the
entire membership of the Company's Board of Directors at a meeting of the Board
called and held for such purpose (after reasonable notice to the Executive and
an opportunity for the Executive, together with the Executive's counsel, to be
heard before the Board) finding that in the good faith opinion of the Board the
Executive was guilty of conduct set forth in the first sentence of this Section
3(d) and specifying the particulars thereof in detail.  For purposes of this
Agreement only, the preparation and filing of fictitious, false or misleading
claims in connection with any federal, state or other third party medical
reimbursement program, or any other violation of any rule or regulation in
respect of any federal, state or other third party medical reimbursement
program by the Company or any subsidiary of the Company shall not be deemed to
constitute "criminal fraud" or "civil fraud".

                 (e)      Good Reason.  For purposes of this Agreement, "Good
Reason" shall mean any of the following actions taken by the Company without
the Executive's express written consent:

                          (i) The assignment to the Executive by the Company of
duties inconsistent with, or the reduction of the powers and functions
associated with, the Executive's position, duties, responsibilities and status
with the Company prior to a Change in Control, or an adverse change in the
Executive's titles or offices as in effect prior to a Change in Control, or any
removal of the Executive from or any failure to re-elect the Executive to any
of such positions, except in connection with the termination of his employment
for Disability, Retirement or Cause or as a result of the Executive's death or
by the Executive other than for Good Reason;





                                      -4-
<PAGE>   5

                          (ii) A reduction by the Company in the Executive's
base salary as in effect on the date hereof or as the same may be increased
from time to time during the term of this Agreement or the Company's failure to
increase (within 12 months of the Executive's last increase in base salary) the
Executive's base salary after a Change in Control in an amount which at least
equals, on a percentage basis, the average annual percentage increase in base
salary for all corporate officers of the Company effected in the preceding 36
months;

                          (iii) Any failure by the Company to continue in
effect any benefit plan, program or arrangement (including, without limitation,
any profit sharing plan, group annuity contract, group life insurance
supplement, or medical, dental, accident and disability plans) in which the
Executive was eligible to participate at the time of a Change in Control (or
any other plans providing the Executive with substantially similar benefits)
(hereinafter referred to as "Benefit Plans"), or the taking of any action by
the Company which would adversely affect the Executive's participation in or
materially reduce the Executive's benefits under any such Benefit Plan or
deprive the Executive of any fringe benefit enjoyed by the Executive at the
time of a Change in Control;

                          (iv) Any failure by the Company to continue in effect
any incentive plan or arrangement (including, without limitations, any bonus or
contingent bonus arrangements and credits and the right to receive performance
awards and similar incentive compensation benefits) in which the Executive is
participating at the time of a Change in Control (or any other plans or
arrangements providing him with substantially similar benefits) (hereinafter
referred to as "Incentive Plans") or the taking of any action by the Company
which would adversely affect the Executive's participation in any such
Incentive Plan or reduce the Executive's benefits under any such Incentive
Plan, expressed as a percentage of his base salary, by more than five
percentage points in any fiscal year as compared to the immediately preceding
fiscal year, or any action to reduce Executive's bonuses under any Incentive
Plan by more than 20% of the average annual bonus previously paid to Executive
with respect to the preceding three fiscal years;

                          (v) Any failure by the Company to continue in effect
any plan or arrangement to receive securities of the Company (including,
without limitation, the Company's 1981 Incentive Stock Option Plan, 1983
Incentive Stock Option Plan, 1984 Nonqualified Stock Option Plan, 1985
Nonqualified Stock Option Plan, 1991 Stock Option Plan and 1993 Stock Option
Plan, Employee Stock Purchase Plan and any other plan or arrangement to receive
and exercise stock options, stock appreciation rights, restricted stock or
grants thereof) in which the Executive is participating or has the right to
participate in prior to a Change in Control (or plans or arrangements providing
him with substantially similar benefits) (hereinafter referred to as
"Securities Plans") or the taking of any action by the Company which would
adversely affect the Executive's





                                      -5-
<PAGE>   6

participation in or materially reduce the Executive's benefits under any such
Securities Plan;

                          (vi) A relocation of the Company's principal

                          (vii) Any failure by the Company to provide the

employment which is not effected pursuant to a Notice of Termination satisfying
the requirements of Section 3(f), and for purposes of this Agreement, no such
purported termination shall be effective; or

                          (xi) Any proposal or request by the Company after the
Effective Date to require that the Executive enter into a non-competition

Executive's employment by the Company for a reason specified in Section 3(b),

Agreement, a "Notice of Termination" shall mean a written notice which shall
indicate whether such termination is for the reason set forth in Section 3(b),

no termination of the





                                      -6-
<PAGE>   7

Executive's employment by the Company shall constitute a termination for
Disability, Retirement or Cause unless such termination is preceded by a Notice
of Termination.

                 (g)      Date of Termination.  "Date of Termination" shall
mean (a) if the Executive's employment is terminated by the Company for
Disability, 30 days after a Notice of Termination is given to the Executive
(provided that the Executive shall not have returned to the performance of the
Executive's duties on a full-time basis during such 30-day period) or (b) if
the Executive's employment is terminated by the Company or the Executive for
any other reason, the date on which the Executive's termination is effective;
provided that, if within 30 days after any Notice of Termination is given to
the Executive by the Company the Executive notifies the Company that a dispute
exists concerning the termination, the Date of Termination shall be the date
the dispute is finally determined whether by mutual agreement by the parties or
upon final judgment, order or decree of a court of competent jurisdiction (the
time for appeal therefrom having expired and no appeal having been perfected).

         4.      Compensation and Benefits upon Termination of Employment.

                 (a)      If the Company shall terminate the Executive's
employment after a Change in Control other than pursuant to Section 3(b), 3(c)
or 3(d) and Section 3(f), or if the Executive shall terminate his employment
for Good Reason, then the Company shall pay to the Executive, as severance
compensation and in consideration of the Executive's adherence to the terms of
Section 5 hereof, the following:

                          (1)     On the Date of Termination, the Company shall
become liable to the Executive for an amount equal to three times the
Executive's average annual compensation from the Company (as reported on Form
W-2 pursuant to applicable provisions of the Internal Revenue Code of 1986, as
amended (the "Code")) for the five years ending prior to the Date of
Termination, which amount shall be paid to the Executive in cash on or before
the fifth day following the Date of Termination.

                          (2)     For a period of three years following the
Date of Termination, the Executive and anyone entitled to claim under or
through the Executive shall be entitled to all benefits under the group
hospitalization plan, health care plan, dental care plan, life or other
insurance or death benefit plan, or other present or future similar group
employee benefit plan or program of the Company for which key executives are
eligible at the date of a Change in Control, to the same extent as if the
Executive had continued to be an employee of the Company during such period and
such benefits shall, to the extent not fully paid under any such plan or
program, be paid by the Company.





                                      -7-
<PAGE>   8

                          (3)     For a period of three years after the Date of
Termination, the Company shall allow the Executive to utilize for his business
and personal use any Company leased automobile previously furnished to him or
an equivalent type and style of automobile and shall reimburse the Executive
for the maintenance and repair costs of such automobile and extend full
insurance coverage relating to such automobile in favor of the Executive, as
additional named insured, during such three-year period.  In addition, the
Executive shall be entitled, at the Executive's sole discretion, to exercise
any option to acquire such automobile pursuant to the terms which may be
provided in the lease agreement for the automobile in question.

                 (b)      The parties hereto agree that the payments provided
in Section 4(a) hereof are reasonable compensation in light of the Executive's
services rendered to the Company and in consideration of the Executive's
adherence to the terms of Section 5 hereof.  Neither party shall contest the
payment of such benefits as constituting an "excess parachute payment" within
the meaning of Section 280G(b)(1) of the Code.  In the event that the Executive
becomes entitled to the compensation and benefits described in Section 4(a)
hereof (the "Compensation Payments") and the Company has determined, based upon
the advise of tax counsel selected by the Company's independent auditors and
acceptable to the Executive, that, as a result of such Compensation Payments
and any other benefits or payments required to be taken into account under Code
Section 280G(b)(2) ("Parachute Payments"), any of such Parachute Payments must
be reported by the Company as "excess parachute payments" and are therefore not
deductible by the Company, the Company shall pay to the Executive at the time
specified in Section 4(a) above an additional amount (the "Gross-Up Payment")
such that the net amount retained by the Executive, after deduction of any of
the tax imposed on the Executive by Section 4999 of the Code (the "Excise Tax")
and any Federal, state and local income tax and Excise Tax upon the Gross-Up
Payment, shall be equal to the Parachute Payments determined prior to the
application of this paragraph.  The value of any non-cash benefits or any
deferred payment or benefit shall be determined by the Company's independent
auditors.  For purposes of determining the amount of the Gross-Up Payment, the
Executive shall be deemed to pay Federal income taxes at the highest marginal
rate of Federal income taxation in the calendar year in which the Gross-Up
Payment is to be made and state and local income taxes at the highest marginal
rates of taxation in the state and locality of the Executive's residence on the
Date of Termination, net of the maximum reduction in Federal income taxes which
could be obtained from deduction of such state and local taxes.  In the event
that the Excise Tax payable by the Executive is subsequently determined to be
less than the amount, if any, taken into account hereunder at the time of
termination of the Executive's employment, the Executive shall repay to the
Company at the time that the amount of such reduction in Excise Tax is finally
determined the portion of the Gross-Up Payment attributable to such reduction
plus interest on the amount of such repayment at the rate provided for in
Section 1274(b)(2)(B)





                                      -8-
<PAGE>   9

of the Code ("Repayment Amount").  In the event that the Excise Tax payable by
the Executive is determined to exceed the amount, if any, taken into account
hereunder at the time of the termination of the Executive's employment
(including by reason of any payment the existence or amount of which cannot be
determined at the time of the Gross-Up Payment), the Company shall make an
additional Gross-Up Payment in respect of such excess (plus any interest and
penalty payable with respect to such excess) immediately prior to the time that
the amount of such excess is required to be paid by Executive ("Additional
Gross-up"), such that the net amount retained by the Executive, after deduction
of any Excise Tax on the Parachute Payments and any Federal, state and local
income tax and Excise Tax upon the Additional Gross-Up Payment, shall be equal
to the Parachute Payments determined prior to the application of this
paragraph.  The obligation to pay any Repayment Amount or Additional Gross-up
shall remain in effect under this Agreement for the entire period during which
the Executive remains liable for the Excise Tax, including the period during
which any applicable statute of limitation remains open.

                 (c)      The payments provided in Section 4(a) above shall be
in lieu of any other severance compensation otherwise payable to Executive
under the Company's established severance compensation policies; provided,
however, that nothing in this Agreement shall affect or impair Executive's
vested rights under any other employee benefit plan or policy of the Company.

                 (d)      Unless the Company determines that any Parachute
Payments made hereunder must be reported as "excess parachute payments" in
accordance with the third sentence of Section 4(b) above, neither party shall
file any return taking the position that the payment of such benefits
constitutes an "excess parachute payment" within the meaning of Section
280G(b)(1) of the Code.  If the Internal Revenue Service proposes an assessment
of Excise Tax against the Executive in excess of the amount, if any, taken into
account at the time specified in Section 4(a), then, if the Company notifies
Executive in writing that the Company elects to contest such assessment at its
expense, unless the Executive waives the right to an Additional Gross-Up
Payment, the Executive (i) shall in good faith cooperate with the Company in
contesting such proposed assessment; and (ii) such Executive shall not settle
such contest without the written consent of the Company.  Any such contest
shall be controlled by the Company, provided, however, that the Executive may
participate in such contest.

which the Executive will receive, both directly and indirectly, significant
benefits and value, and in consideration of the Covenant Payments payable by
the Company to the Executive under this Agreement, the Executive hereby agrees
that he will not, without the prior written consent of the Company, alone or in
conjunction with any other party, solicit or attempt to solicit any employee,
consultant, contractor, independent broker or other personnel of the Company to
terminate, alter or lessen that party's affiliation with the Company or to
violate the terms of any agreement or understanding between such employee,
consultant, contractor or other person and the Company.

                 (e)      Acknowledgement  The parties acknowledge and agree
that the covenants of the Executive in Subsection (b) through (d) are and shall
be treated, under law, as "ancillary to the sale of the Company's business."
The parties acknowledge and agree that the Protective Covenants are reasonable
as to time, scope and territory given the Company's need to protect its trade
secrets and confidential business information and given the substantial
payments and benefits to which the Executive is entitled in connection with the
Merger and otherwise pursuant to this Agreement.

                 (f)      Remedies  The parties acknowledge that any breach or
threatened breach of a Protective Covenant by the Executive is reasonably
likely to result in irreparable injury to the Company, and therefore, in
addition to all remedies provided at law or in equity, the Executive agrees
that the Company shall be entitled to a temporary restraining order and a
permanent injunction to prevent a breach or contemplated breach of the
Protective Covenant.  If the Company seeks an injunction, the Executive waives
any requirement that the Company post a bond or any other security.

         6.      No Obligation to Mitigate Damages; No Effect on Other 
Contractual Rights.

                 (a)      All compensation and benefits provided to the
Executive under this Agreement are in consideration of the Executive's services
rendered to the Company and





                                      -12-
<PAGE>   13

of the Executive's adhering to the terms set forth in Section 5 hereof and the
Executive shall not be required to mitigate damages or the amount of any
payment provided for under this Agreement by seeking other employment or
otherwise, nor shall the amount of any payment provided for under this
Agreement be reduced by any compensation earned by the Executive as the result
of employment by another employer after the Date of Termination, or otherwise.

                 (b)      The provisions of this Agreement, and any payment
provided for hereunder, shall not reduce any amounts otherwise payable, or in
any way diminish the Executive's existing rights, or rights which would accrue
solely as a result of the passage of time, under any Benefit Plan, Incentive
Plan or Securities Plan, employment agreement or other contract, plan or
arrangement.

         7.      Successor to the Company.

                 (a)      The Company will require any successor or assign
(whether direct or indirect, by purchase, merger, consolidation or otherwise)
to all or substantially all of the business and/or assets of the Company, by
agreement in form and substance satisfactory to the Executive, expressly,
absolutely and unconditionally to assume and agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform it if no such succession or assignment had taken place.  Any failure of
the Company to obtain such agreement prior to the effectiveness of any such
succession or assignment shall be a material breach of this Agreement and shall
entitle the Executive to terminate the Executive's employment for Good Reason.
As used in this Agreement, "Company" shall mean the Company as hereinbefore
defined and any successor or assign to its business and/or assets as aforesaid,
including without limitation, the Surviving Company in the Merger.  If at any
time during the term of this Agreement the Executive is employed by any
corporation a majority of the voting securities of which is then owned by the
Company, "Company" as used in Sections 3, 4, 12 and 14 hereof shall in addition
include such employer.  In such event, the Company agrees that it shall pay or
shall cause such employer to pay any amounts owed to the Executive pursuant to
Section 4 hereof.

                 (b)      This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal and legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees.  If the
Executive should die while any amounts are still payable to him or her
hereunder, all such amounts, unless otherwise provided herein, shall be paid in
accordance with the terms of this Agreement to the Executive's devisee,
legatee, or the designee or, if there be no such designee, to the Executive's
estate.

writing in accordance herewith, except that notices of change of address shall
be effective only upon receipt.

         9.      Miscellaneous.  No provisions of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in writing signed by the Executive and the Company.  No waiver by
either party hereto at any time of any breach by the other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed
by such other party shall be deemed a waiver of similar or dissimilar
provisions or conditions at the same or at any prior or subsequent time.
Neither this Agreement nor the Merger shall diminish or waive in any way the
rights of Executive under the Prior Agreement, which as amended by this
Agreement, shall continue to be applicable to Executive's employment by the
Surviving Company after the Merger.  No agreements or representations, oral or
otherwise, express or implied, with respect to the subject matter hereof have
been made by either party which are not set forth expressly in this Agreement.
This Agreement shall be governed by and construed in accordance with the laws
of the State of Georgia.

         10.     Validity.  The invalidity or unenforceability of any
provisions of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, which shall remain in full force and
effect.

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

         12.     Legal Fees and Expenses.  The Company shall pay all legal
fees, expenses and damages which the Executive may incur as a result of the
Executive's instituting legal action to enforce his rights hereunder, or in the
event the Company contests the validity, enforceability or the Executive's
interpretation of, or determinations under, this Agreement.  If the Executive
is the prevailing party or recovers any damages in such legal action, the
Executive shall be entitled to receive in addition thereto pre-judgment and
post-judgment interest on the amount of such damages.

         13.     Severability, Modification.  All provisions of this Agreement
are severable from one another, and the unenforceability or invalidity of any
provision of this Agreement shall not affect the validity or enforceability of
the remaining provisions of this Agreement, but such remaining provisions shall
be interpreted and construed in such a manner as to carry out fully the
intention of the parties.  Should any judicial body interpreting this Agreement
deem any provision of this Agreement to be unreasonably broad in time,
territory, scope or otherwise, it is the intent and desire of the parties that
such judicial body, to the greatest extent possible, reduce the breadth of such
provision to the maximum legally allowable parameters rather than deeming such
provision totally unenforceable or invalid.

         14.     Confidentiality.  The Executive acknowledges that he or she
has previously entered into, and continues to be bound by the terms of, a
Confidentiality Agreement with the Company.

         15.     Agreement Not an Employment Contract.  This Agreement shall
not be deemed to constitute or be deemed ancillary to an employment contract
between the Company and the Executive, and nothing herein shall be deemed to
give the Executive the right to continue in the employ of the Company or to
eliminate the right of the Company to discharge the Executive at any time.

                  AMENDED AND RESTATED SEVERANCE COMPENSATION
                                      AND
                         RESTRICTIVE COVENANT AGREEMENT


         This Amended and Restated Severance Compensation and Restrictive
Covenant Agreement ("Agreement") is dated as of October 2, 1995 and is
effective as of the date provided in Section 1(a) below between Healthdyne,
Inc., a Georgia corporation (the "Company"), and Parker H. Petit (the
"Executive").

         WHEREAS, the Company, having determined that it was appropriate to
reinforce and encourage the continued attention and dedication of members of
the Company's management, including the Executive, to their assigned duties,
entered into that Severance Compensation Agreement dated February 4, 1988, as
amended from time to time thereafter, with the Executive ("Prior Agreement");
and

         WHEREAS, the Company has determined that it desires to amend and
restate the Prior Agreement and to include, in addition to severance
provisions, certain restrictive covenants from the Executive; and

         WHEREAS, simultaneously with its execution of this Agreement, the
Company is entering into an Agreement and Plan of Merger (the "Merger
Agreement") with T&H Acquisition Company ("Newco") and Tokos Medical
Corporation (Delaware) ("TM"), pursuant to which the Company and TM will merge
with and into Newco (the "Surviving Company") (such transaction shall hereafter
be referred to as the "Merger"), and such Merger will constitute a Change in
Control within the meaning of the Prior Agreement and as defined herein; and

         WHEREAS, TM's willingness to execute the Merger Agreement is
conditioned on Executive entering into the restrictive covenants contained in
this Agreement, and the parties hereto acknowledge the reasonableness of such
covenants, given the significant value that Executive will receive, directly
and indirectly, as a result of the Merger and given the payments to be made to
Executive pursuant to this Agreement in consideration of these covenants; and

         WHEREAS, the Board of Directors of the Company has determined that it
is appropriate to reinforce and encourage the continued attention and
dedication of members of the Company's management, including the Executive, to
their assigned duties without distraction in potentially disturbing
circumstances arising from the Merger or any subsequent Change in Control; and

         WHEREAS, the severance benefits payable by the Company to Executive as
provided herein are in part intended to ensure that Executive receives
reasonable
<PAGE>   2

compensation given the specific circumstances of Executive's employment history
with the Company; and

         WHEREAS, it is intended that neither this Agreement nor the Merger
shall diminish or waive in any way the rights of the Executive under the Prior
Agreement, which, as amended by this Agreement, shall continue to be applicable
to Executive's employment by the Surviving Company after the Merger;

         NOW, THEREFORE, in consideration of their respective obligations to
one another set forth in this Agreement, and other good and valuable
consideration, the receipt, sufficiency and adequacy of which the parties
hereby acknowledge, the parties to this Agreement, intending to be legally
bound, hereby agree as follows:

         1.      Term.

                 (a)  This Agreement shall become effective immediately prior
to the Effective Time of the Merger (as defined in Section 2.2 of the Merger
Agreement), provided that the Executive is still employed by the Company at
such time.  If the Merger does not become effective on or before May 31, 1996
or the Executive is not employed by the Company at the Effective Time, then
this Agreement shall be deemed never to have been in effect, and the Prior
Agreement shall remain in effect, unamended by this Agreement.

                 (b)  This Agreement shall terminate, except to the extent that
any obligation of the Company hereunder remains unpaid as of such time, upon
the earliest of (i) three years after the Effective Time if a Change in Control
(other than the Merger) has not occurred after the Effective Time; (ii) the
Date of Termination of the Executive based on death, Disability (as defined in
Section 3(b)), Retirement (as defined in Section 3(c)) or Cause (as defined in
Section 3(d)) or by the Executive other than for Good Reason (as defined in
Section 3(e)); or (iii) three years from the date of a Change in Control (as
defined in Section 2) occurring after the Merger if the Executive's employment
with the Company has not terminated as of such time.

         2.      Change in Control.  For purposes of this Agreement, a Change
in Control shall be deemed to have occurred if (a) there shall be consummated
(i) any consolidation or merger of the Company in which the Company is not the
continuing or surviving corporation or pursuant to which shares of the
Company's common stock would be converted into cash, securities or other
property, other than a merger of the Company in which the holders of the
Company's common stock immediately prior to the merger have the same
proportionate ownership of common stock of the surviving corporation
immediately after the merger, or (ii) any sale, lease, exchange or other
transfer (in one





                                      -2-
<PAGE>   3

transaction or a series of related transactions) of all, or substantially all,
of the assets of the Company, or (b) the stockholders of the Company approve
any plan or proposal for the liquidation or dissolution of the Company, or (c)
any person (as such term is used in Sections 13(d) and 14(d)(2) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act")), shall become
the beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act)
of 30% of the Company's outstanding Common Stock, or (d) during any period of
two consecutive years, individuals who at the beginning of such period
constitute the entire Board of Directors of the Company shall cease for any
reason to constitute a majority thereof unless the election, or the nomination
for election by the Company's stockholders, of each new director was approved
by a vote of at least two-thirds of the directors then still in office who were
directors at the beginning of the period; provided, however, that, in the
absence of a majority vote of the directors specified in subsection (d) of this
Section 2 to the contrary, the sale, lease, exchange or other disposition (in
one transaction or a series of related transactions) of less than 70% of the
total fair market value of all of the assets of the Company immediately prior
to such transaction or transactions shall not be deemed to be a Change in
Control and provided further that the transaction or transactions which involve
the sale, lease, exchange or other disposition of 70% or more of the total fair
market value of all of the assets of the Company immediately prior to such
transaction or transactions shall be deemed to be a Change in Control even if
approved by the Board of Directors of the Company.

         3.      Termination Following Change in Control.

                 (a)      If the Executive is still an employee of the Company
at the Effective Time or at the time of any other Change in Control, the
Executive shall be entitled to the compensation and benefits provided in
Section 4 upon the subsequent termination of the Executive's employment with
the Company by the Executive or by the Company during the term of this
Agreement, unless such termination is as a result of (i) the Executive's death;
(ii) the Executive's Disability; (iii) the Executive's Retirement; (iv) the
Executive's termination by the Company for Cause; or (v) the Executive's
decision to terminate employment other than for Good Reason.

                 (b)      Disability.  The term "Disability" as used in this
Agreement shall mean termination of the Executive's employment by the Company
as a result of the Executive's incapacity due to physical or mental illness,
provided that the Executive shall have been absent from his duties with the
Company on a full-time basis for six consecutive months and such absence shall
have continued unabated for 30 days after Notice of Termination as described in
Section 3(f) is thereafter given to the Executive by the Company.





                                      -3-
<PAGE>   4

                 (c)      Retirement.  The term "Retirement" as used in this
Agreement shall mean termination of the Executive's employment by the Company
based on the Executive's having attained age 65 or such later retirement age as
shall have been established pursuant to a written agreement between the Company
and the Executive.  Termination of Executive's employment at a time when
Executive is eligible to receive benefits under the Company's Retirement
Benefit Award or the Company's Protective Umbrella for Lifelong Security of
Employees Program shall not constitute Retirement unless Executive shall have
attained such age.

                 (d)      Cause.  The term "Cause" for purposes of this
Agreement shall mean the Company's termination of the Executive's employment on
the basis of criminal or civil fraud on the part of the Executive involving a
material amount of funds of the Company.  Notwithstanding the foregoing, the
Executive shall not be deemed to have been terminated for Cause unless and
until there shall have been delivered to the Executive a copy of a resolution
duly adopted by the affirmative vote of not less than three-quarters of the
entire membership of the Company's Board of Directors at a meeting of the Board
called and held for such purpose (after reasonable notice to the Executive and
an opportunity for the Executive, together with the Executive's counsel, to be
heard before the Board) finding that in the good faith opinion of the Board the
Executive was guilty of conduct set forth in the first sentence of this Section
3(d) and specifying the particulars thereof in detail.  For purposes of this
Agreement only, the preparation and filing of fictitious, false or misleading
claims in connection with any federal, state or other third party medical
reimbursement program, or any other violation of any rule or regulation in
respect of any federal, state or other third party medical reimbursement
program by the Company or any subsidiary of the Company shall not be deemed to
constitute "criminal fraud" or "civil fraud".

                 (e)      Good Reason.  For purposes of this Agreement, "Good
Reason" shall mean any of the following actions taken by the Company without
the Executive's express written consent:

                          (i) The assignment to the Executive by the Company of
duties inconsistent with, or the reduction of the powers and functions
associated with, the Executive's position, duties, responsibilities and status
with the Company prior to a Change in Control, or an adverse change in the
Executive's titles or offices as in effect prior to a Change in Control, or any
removal of the Executive from or any failure to re-elect the Executive to any
of such positions, except in connection with the termination of his employment
for Disability, Retirement or Cause or as a result of the Executive's death or
by the Executive other than for Good Reason;





                                      -4-
<PAGE>   5

                          (ii) A reduction by the Company in the Executive's
base salary as in effect on the date hereof or as the same may be increased
from time to time during the term of this Agreement or the Company's failure to
increase (within 12 months of the Executive's last increase in base salary) the
Executive's base salary after a Change in Control in an amount which at least
equals, on a percentage basis, the average annual percentage increase in base
salary for all corporate officers of the Company effected in the preceding 36
months;

                          (iii) Any failure by the Company to continue in
effect any benefit plan, program or arrangement (including, without limitation,
any profit sharing plan, group annuity contract, group life insurance
supplement, or medical, dental, accident and disability plans) in which the
Executive was eligible to participate at the time of a Change in Control (or
any other plans providing the Executive with substantially similar benefits)
(hereinafter referred to as "Benefit Plans"), or the taking of any action by
the Company which would adversely affect the Executive's participation in or
materially reduce the Executive's benefits under any such Benefit Plan or
deprive the Executive of any fringe benefit enjoyed by the Executive at the
time of a Change in Control;

                          (iv) Any failure by the Company to continue in effect
any incentive plan or arrangement (including, without limitations, any bonus or
contingent bonus arrangements and credits and the right to receive performance
awards and similar incentive compensation benefits) in which the Executive is
participating at the time of a Change in Control (or any other plans or
arrangements providing him with substantially similar benefits) (hereinafter
referred to as "Incentive Plans") or the taking of any action by the Company
which would adversely affect the Executive's participation in any such
Incentive Plan or reduce the Executive's benefits under any such Incentive
Plan, expressed as a percentage of his base salary, by more than five
percentage points in any fiscal year as compared to the immediately preceding
fiscal year, or any action to reduce Executive's bonuses under any Incentive
Plan by more than 20% of the average annual bonus previously paid to Executive
with respect to the preceding three fiscal years;

                          (v) Any failure by the Company to continue in effect
any plan or arrangement to receive securities of the Company (including,
without limitation, the Company's 1981 Incentive Stock Option Plan, 1983
Incentive Stock Option Plan, 1984 Nonqualified Stock Option Plan, 1985
Nonqualified Stock Option Plan, 1991 Stock Option Plan and 1993 Stock Option
Plan, Employee Stock Purchase Plan and any other plan or arrangement to receive
and exercise stock options, stock appreciation rights, restricted stock or
grants thereof) in which the Executive is participating or has the right to
participate in prior to a Change in Control (or plans or arrangements providing
him with substantially similar benefits) (hereinafter referred to as
"Securities Plans") or the taking of any action by the Company which would
adversely affect the Executive's





                                      -5-
<PAGE>   6

participation in or materially reduce the Executive's benefits under any such
Securities Plan;

                          (vi) A relocation of the Company's principal
executive offices to a location outside of Marietta, Georgia, or the
Executive's relocation to any place other than the location at which the
Executive performed the Executive's duties prior to a Change in Control, except
for required travel by the Executive on the Company's business to an extent
substantially consistent with the Executive's business travel obligations
immediately prior to a Change in Control;

                          (vii) Any failure by the Company to provide the
Executive with the number of paid vacation days (or compensation therefor at
termination of employment) accrued to the Executive through the date of a
Change in Control, together with any earned but unused vacation days for the
vacation year in question;

                          (viii) Any material breach by the Company of any
provision of this Agreement;

                          (ix) Any failure by the Company to obtain the
assumption of this Agreement by any successor or assign of the Company effected
in accordance with the provisions of Section 7(a) hereof;

                          (x) Any purported termination of the Executive's
employment which is not effected pursuant to a Notice of Termination satisfying
the requirements of Section 3(f), and for purposes of this Agreement, no such
purported termination shall be effective; or

                          (xi) Any proposal or request by the Company after the
Effective Date to require that the Executive enter into a non-competition
agreement with the Company where the terms of such agreement as to its scope or
duration are greater than the terms set forth in Section 5 hereof.

                 (f)      Notice of Termination.  Any termination of the
Executive's employment by the Company for a reason specified in Section 3(b),
3(c) or 3(d) shall be communicated to the Executive by a Notice of Termination
prior to the effective date of the termination.  For purposes of this
Agreement, a "Notice of Termination" shall mean a written notice which shall
indicate whether such termination is for the reason set forth in Section 3(b),
3(c) or 3(d) and which sets forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive's
employment under the provision so indicated.  For purposes of this Agreement,
no termination of the





                                      -6-
<PAGE>   7

Executive's employment by the Company shall constitute a termination for
Disability, Retirement or Cause unless such termination is preceded by a Notice
of Termination.

                 (g)      Date of Termination.  "Date of Termination" shall
mean (a) if the Executive's employment is terminated by the Company for
Disability, 30 days after a Notice of Termination is given to the Executive
(provided that the Executive shall not have returned to the performance of the
Executive's duties on a full-time basis during such 30-day period) or (b) if
the Executive's employment is terminated by the Company or the Executive for
any other reason, the date on which the Executive's termination is effective;
provided that, if within 30 days after any Notice of Termination is given to
the Executive by the Company the Executive notifies the Company that a dispute
exists concerning the termination, the Date of Termination shall be the date
the dispute is finally determined whether by mutual agreement by the parties or
upon final judgment, order or decree of a court of competent jurisdiction (the
time for appeal therefrom having expired and no appeal having been perfected).

         4.      Compensation and Benefits upon Termination of Employment.

                 (a)      If the Company shall terminate the Executive's
employment after a Change in Control other than pursuant to Section 3(b), 3(c)
or 3(d) and Section 3(f), or if the Executive shall terminate his employment
for Good Reason, then the Company shall pay to the Executive, as severance
compensation and in consideration of the Executive's adherence to the terms of
Section 5 hereof, the following:

                          (1)     On the Date of Termination, the Company shall
become liable to the Executive for an amount equal to three times the
Executive's average annual compensation from the Company (as reported on Form
W-2 pursuant to applicable provisions of the Internal Revenue Code of 1986, as
amended (the "Code")) for the five years ending prior to the Date of
Termination, which amount shall be paid to the Executive in cash on or before
the fifth day following the Date of Termination.

                          (2)     For a period of three years following the
Date of Termination, the Executive and anyone entitled to claim under or
through the Executive shall be entitled to all benefits under the group
hospitalization plan, health care plan, dental care plan, life or other
insurance or death benefit plan, or other present or future similar group
employee benefit plan or program of the Company for which key executives are
eligible at the date of a Change in Control, to the same extent as if the
Executive had continued to be an employee of the Company during such period and
such benefits shall, to the extent not fully paid under any such plan or
program, be paid by the Company.

                          (3)     For a period of three years after the Date of
Termination, the Company shall allow the Executive to utilize for his business
and personal use any Company leased automobile previously furnished to him or
an equivalent type and style of automobile and shall reimburse the Executive
for the maintenance and repair costs of such automobile and extend full
insurance coverage relating to such automobile in favor of the Executive, as
additional named insured, during such three-year period.  In addition, the
Executive shall be entitled, at the Executive's sole discretion, to exercise
any option to acquire such automobile pursuant to the terms which may be
provided in the lease agreement for the automobile in question.

                 (b)      The parties hereto agree that the payments provided
in Section 4(a) hereof are reasonable compensation in light of the Executive's
services rendered to the Company and in consideration of the Executive's
adherence to the terms of Section 5 hereof.  Neither party shall contest the
payment of such benefits as constituting an "excess parachute payment" within
the meaning of Section 280G(b)(1) of the Code.  In the event that the Executive
becomes entitled to the compensation and benefits described in Section 4(a)
hereof (the "Compensation Payments") and the Company has determined, based upon
the advise of tax counsel selected by the Company's independent auditors and
acceptable to the Executive, that, as a result of such Compensation Payments
and any other benefits or payments required to be taken into account under Code
Section 280G(b)(2) ("Parachute Payments"), any of such Parachute Payments must
be reported by the Company as "excess parachute payments" and are therefore not
deductible by the Company, the Company shall pay to the Executive at the time
specified in Section 4(a) above an additional amount (the "Gross-Up Payment")
such that the net amount retained by the Executive, after deduction of any of
the tax imposed on the Executive by Section 4999 of the Code (the "Excise Tax")
and any Federal, state and local income tax and Excise Tax upon the Gross-Up
Payment, shall be equal to the Parachute Payments determined prior to the
application of this paragraph.  The value of any non-cash benefits or any
deferred payment or benefit shall be determined by the Company's independent
auditors.  For purposes of determining the amount of the Gross-Up Payment, the
Executive shall be deemed to pay Federal income taxes at the highest marginal
rate of Federal income taxation in the calendar year in which the Gross-Up
Payment is to be made and state and local income taxes at the highest marginal
rates of taxation in the state and locality of the Executive's residence on the
Date of Termination, net of the maximum reduction in Federal income taxes which
could be obtained from deduction of such state and local taxes.  In the event
that the Excise Tax payable by the Executive is subsequently determined to be
less than the amount, if any, taken into account hereunder at the time of
termination of the Executive's employment, the Executive shall repay to the
Company at the time that the amount of such reduction in Excise Tax is finally
determined the portion of the Gross-Up Payment attributable to such reduction
plus interest on the amount of such repayment at the rate provided for in
Section 1274(b)(2)(B)





                                      -8-
<PAGE>   9

of the Code ("Repayment Amount").  In the event that the Excise Tax payable by
the Executive is determined to exceed the amount, if any, taken into account
hereunder at the time of the termination of the Executive's employment
(including by reason of any payment the existence or amount of which cannot be
determined at the time of the Gross-Up Payment), the Company shall make an
additional Gross-Up Payment in respect of such excess (plus any interest and
penalty payable with respect to such excess) immediately prior to the time that
the amount of such excess is required to be paid by Executive ("Additional
Gross-up"), such that the net amount retained by the Executive, after deduction
of any Excise Tax on the Parachute Payments and any Federal, state and local
income tax and Excise Tax upon the Additional Gross-Up Payment, shall be equal
to the Parachute Payments determined prior to the application of this
paragraph.  The obligation to pay any Repayment Amount or Additional Gross-up
shall remain in effect under this Agreement for the entire period during which
the Executive remains liable for the Excise Tax, including the period during
which any applicable statute of limitation remains open.

                 (c)      The payments provided in Section 4(a) above shall be
in lieu of any other severance compensation otherwise payable to Executive
under the Company's established severance compensation policies; provided,
however, that nothing in this Agreement shall affect or impair Executive's
vested rights under any other employee benefit plan or policy of the Company.

                 (d)      Unless the Company determines that any Parachute
Payments made hereunder must be reported as "excess parachute payments" in
accordance with the third sentence of Section 4(b) above, neither party shall
file any return taking the position that the payment of such benefits
constitutes an "excess parachute payment" within the meaning of Section
280G(b)(1) of the Code.  If the Internal Revenue Service proposes an assessment
of Excise Tax against the Executive in excess of the amount, if any, taken into
account at the time specified in Section 4(a), then, if the Company notifies
Executive in writing that the Company elects to contest such assessment at its
expense, unless the Executive waives the right to an Additional Gross-Up
Payment, the Executive (i) shall in good faith cooperate with the Company in
contesting such proposed assessment; and (ii) such Executive shall not settle
such contest without the written consent of the Company.  Any such contest
shall be controlled by the Company, provided, however, that the Executive may
participate in such contest.

         5.      Protective Covenants

         (a)     Definitions

                 This Subsection sets forth the definition of certain
capitalized terms used in Subsections (a) through (f) of this Section 5.

                          (i)     "Competing Business" shall mean a business
(other than the Company) that, directly or through a controlled subsidiary or
through an affiliate, (a) develops, markets and/or sells products for uterine
contraction monitoring in the home or products that would be used in lieu of or

without limitation, programs for monitoring patients who are at risk of preterm
delivery, programs for managing patients suffering from obstetrical
hypertension or diabetes, infusion therapy services involving drugs to control
preterm labor, nursing services and maternity management services for both low

business, or a division of that business, derived more than twenty percent
(20%) of its gross revenues or more than $2,000,000 in gross revenues from the
development, marketing or sale of Competing Products and/or the provision of
Competing Services; provided, however, that neither Healthdyne Technologies,
Inc., a Georgia corporation and the manufacturer of medical devices utilized by
the Company ("HTI"), nor Healthdyne Information Enterprises, Inc., a Georgia
corporation engaged in healthcare information services ("HIE"), shall
constitute a Competing Business unless it provides patient care services to
obstetrical patients in the home.

                          (ii)    "Competitive Position" shall mean: (A) the
Executive's direct or indirect equity ownership (excluding ownership of less
than one percent (1%) of the outstanding common stock of any publicly held
corporation) or control of any portion of any Competing Business; or (B) any
employment, consulting, partnership, advisory, directorship, agency,
promotional or independent contractor arrangement between the Executive and any
Competing Business where the Executive performs services for the Competing
Business substantially similar to those the Executive performed for the
Company, provided, however that Executive shall not be deemed to have a
Competitive Position solely because of (y) Executive's position as a director
or holder of more than one percent (1%) of the outstanding stock of HTI or HIE,
if Executive had such position at the Effective Time or (z) Executive's
services for a Competing Business that are not directly related to the sale of
Competing Products or the provision of Competing Services, unless more than
thirty-five percent (35%) of the gross revenues of the





                                      -10-
<PAGE>   11

Competing Business are derived from the sale of Competing Products and/or the
provision of Competing Services.

                          (iii)   "Covenant Payments" shall mean the payments
and benefits under this Agreement that are made or provided to the Executive
under Section 4 of this Agreement in exchange for the Executive's agreeing to

Covenants").  The parties hereby stipulate that the value of the Covenant
Payments is Eight Hundred Sixty Five Thousand Dollars ($865,000).

                          (iv)    "Covenant Period" shall mean the period of
time from the Effective Date to the date that is three (3) years after the
later of (A) the Effective Date or (B) the effective date of any Change in
Control that occurs within three years after the Effective Date where the
Executive's employment with the Company has not terminated as of the effective
date of such subsequent Change in Control.

                          (v)     "Customers" shall mean actual customers,
clients, referral sources or managed care organizations or actively sought
prospective customers,  clients, referral sources or managed care organizations
of the Company (A) during the two (2) years prior to the Effective Date and (B)
during the Covenant Period.

                          (vi)    "Restricted Territory" shall mean a one
hundred fifty (150) mile radius of the currently existing Company locations
listed on Schedule A, all of which are locations from which the Company
Products are developed, produced, marketed, sold or distributed.  The Executive
agrees to sign any amendment to Schedule A proposed by the Company, which
amendment adds or deletes Company locations so that Schedule A accurately
reflects all then current Company locations from which the Company's products
or services are developed, marketed, sold or provided.

                 (b)      Limitation on Competition  Ancillary to and as a
condition precedent to the Merger, in connection with which the Executive will
receive, both directly and indirectly, significant benefits and value, and in
consideration of the Covenant Payments payable by the Company to the Executive
under this Agreement, the Executive agrees that during the Covenant Period, the
Executive will not, without the prior written consent of the Company, anywhere
within the Restricted Territory, either directly or indirectly, alone or in
conjunction with any other party, accept, enter into or take any action in
conjunction with or in furtherance of a Competitive Position (other than action
to reject an unsolicited offer of a Competitive Position).

                 (c)      Limitation on Soliciting Customers  Ancillary to and
as a condition precedent to the Merger, in connection with which the Executive
will receive, both





                                      -11-
<PAGE>   12

directly and indirectly, significant benefits and value, and in consideration
of the Covenant Payments payable by the Company to the Executive under this
Agreement, the Executive agrees that during the Covenant Period, the Executive
will not, without the prior written consent of the Company, alone or in
conjunction with any other party, solicit, divert or appropriate or attempt to
solicit, divert or appropriate on behalf of a Competing Business with which
Executive has a Competitive Position any Customer located in the Restricted
Territory (or any other Customer with which the Executive had any direct
contact on behalf of the Company) for the purpose of providing the Customer or
having the Customer provided with a Competing Product or Competing Service.

                 (d)      Limitation on Soliciting Personnel or Other Parties
Ancillary to and as a condition precedent to the Merger, in connection with
which the Executive will receive, both directly and indirectly, significant
benefits and value, and in consideration of the Covenant Payments payable by
the Company to the Executive under this Agreement, the Executive hereby agrees
that he will not, without the prior written consent of the Company, alone or in
conjunction with any other party, solicit or attempt to solicit any employee,
consultant, contractor, independent broker or other personnel of the Company to
terminate, alter or lessen that party's affiliation with the Company or to
violate the terms of any agreement or understanding between such employee,
consultant, contractor or other person and the Company.

                 (e)      Acknowledgement  The parties acknowledge and agree
that the covenants of the Executive in Subsection (b) through (d) are and shall
be treated, under law, as "ancillary to the sale of the Company's business."
The parties acknowledge and agree that the Protective Covenants are reasonable
as to time, scope and territory given the Company's need to protect its trade
secrets and confidential business information and given the substantial
payments and benefits to which the Executive is entitled in connection with the
Merger and otherwise pursuant to this Agreement.

                 (f)      Remedies  The parties acknowledge that any breach or
threatened breach of a Protective Covenant by the Executive is reasonably
likely to result in irreparable injury to the Company, and therefore, in
addition to all remedies provided at law or in equity, the Executive agrees
that the Company shall be entitled to a temporary restraining order and a
permanent injunction to prevent a breach or contemplated breach of the
Protective Covenant.  If the Company seeks an injunction, the Executive waives
any requirement that the Company post a bond or any other security.

         6.      No Obligation to Mitigate Damages; No Effect on Other 
Contractual Rights.

                 (a)      All compensation and benefits provided to the
Executive under this Agreement are in consideration of the Executive's services
rendered to the Company and of the Executive's adhering to the terms set forth
in Section 5 hereof and the Executive shall not be required to mitigate damages
or the amount of any payment provided for under this Agreement by seeking other
employment or otherwise, nor shall the amount of any payment provided for under
this Agreement be reduced by any compensation earned by the Executive as the
result of employment by another employer after the Date of Termination, or
otherwise.

                 (b)      The provisions of this Agreement, and any payment
provided for hereunder, shall not reduce any amounts otherwise payable, or in
any way diminish the Executive's existing rights, or rights which would accrue
solely as a result of the passage of time, under any Benefit Plan, Incentive
Plan or Securities Plan, employment agreement or other contract, plan or
arrangement.

         7.      Successor to the Company.

                 (a)      The Company will require any successor or assign
(whether direct or indirect, by purchase, merger, consolidation or otherwise)
to all or substantially all of the business and/or assets of the Company, by
agreement in form and substance satisfactory to the Executive, expressly,
absolutely and unconditionally to assume and agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform it if no such succession or assignment had taken place.  Any failure of
the Company to obtain such agreement prior to the effectiveness of any such
succession or assignment shall be a material breach of this Agreement and shall
entitle the Executive to terminate the Executive's employment for Good Reason.
As used in this Agreement, "Company" shall mean the Company as hereinbefore
defined and any successor or assign to its business and/or assets as aforesaid,
including without limitation, the Surviving Company in the Merger.  If at any
time during the term of this Agreement the Executive is employed by any
corporation a majority of the voting securities of which is then owned by the
Company, "Company" as used in Sections 3, 4, 12 and 14 hereof shall in addition
include such employer.  In such event, the Company agrees that it shall pay or
shall cause such employer to pay any amounts owed to the Executive pursuant to
Section 4 hereof.

                 (b)      This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal and legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees.  If the
Executive should die while any amounts





                                      -13-
<PAGE>   14

are still payable to him or her hereunder, all such amounts, unless otherwise
provided herein, shall be paid in accordance with the terms of this Agreement
to the Executive's devisee, legatee, or the designee or, if there be no such
designee, to the Executive's estate.

         8.      Notice.  For purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
registered mail, return receipt required, postage prepaid, as follows:

                 If to Company:

                          Healthdyne, Inc.

                          Marietta, Georgia 30067

                 If to Executive:

                          Marietta, Georgia  30067

or such other address as either party may have furnished to the other in
writing in accordance herewith, except that notices of change of address shall
be effective only upon receipt.

         9.      Miscellaneous.  No provisions of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in writing signed by the Executive and the Company.  No waiver by
either party hereto at any time of any breach by the other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed
by such other party shall be deemed a waiver of similar or dissimilar
provisions or conditions at the same or at any prior or subsequent time.
Neither this Agreement nor the Merger shall diminish or waive in any way the
rights of Executive under the Prior Agreement, which as amended by this
Agreement, shall continue to be applicable to Executive's employment by the
Surviving Company after the Merger.  No agreements or representations, oral or
otherwise, express or implied, with respect to the subject matter hereof have
been made by either party which are not set forth expressly in this Agreement.
This Agreement shall be governed by and construed in accordance with the laws
of the State of Georgia.

<PAGE>   15

         10.     Validity.  The invalidity or unenforceability of any
provisions of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, which shall remain in full force and
effect.

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

         12.     Legal Fees and Expenses.  The Company shall pay all legal
fees, expenses and damages which the Executive may incur as a result of the
Executive's instituting legal action to enforce his rights hereunder, or in the
event the Company contests the validity, enforceability or the Executive's
interpretation of, or determinations under, this Agreement.  If the Executive
is the prevailing party or recovers any damages in such legal action, the
Executive shall be entitled to receive in addition thereto pre-judgment and
post-judgment interest on the amount of such damages.

         13.     Severability, Modification.  All provisions of this Agreement
are severable from one another, and the unenforceability or invalidity of any
provision of this Agreement shall not affect the validity or enforceability of
the remaining provisions of this Agreement, but such remaining provisions shall
be interpreted and construed in such a manner as to carry out fully the
intention of the parties.  Should any judicial body interpreting this Agreement
deem any provision of this Agreement to be unreasonably broad in time,
territory, scope or otherwise, it is the intent and desire of the parties that
such judicial body, to the greatest extent possible, reduce the breadth of such
provision to the maximum legally allowable parameters rather than deeming such
provision totally unenforceable or invalid.

         14.     Confidentiality.  The Executive acknowledges that he or she
has previously entered into, and continues to be bound by the terms of, a
Confidentiality Agreement with the Company.

         15.     Agreement Not an Employment Contract.  This Agreement shall
not be deemed to constitute or be deemed ancillary to an employment contract
between the Company and the Executive, and nothing herein shall be deemed to
give the Executive the right to continue in the employ of the Company or to
eliminate the right of the Company to discharge the Executive at any time.

                  AMENDED AND RESTATED SEVERANCE COMPENSATION
                                      AND
                         RESTRICTIVE COVENANT AGREEMENT


         This Amended and Restated Severance Compensation and Restrictive
Covenant Agreement ("Agreement") is dated as of October 2, 1995 and is
effective as of the date provided in Section 1(a) below between Healthdyne,
Inc., a Georgia corporation (the "Company"), and J. Paul Yokubinas (the
"Executive").

         WHEREAS, the Company, having determined that it was appropriate to
reinforce and encourage the continued attention and dedication of members of
the Company's management, including the Executive, to their assigned duties,
entered into that Severance Compensation Agreement dated October 27, 1993, as
amended from time to time thereafter, with the Executive ("Prior Agreement");
and

         WHEREAS, the Company has determined that it desires to amend and
restate the Prior Agreement and to include, in addition to severance
provisions, certain restrictive covenants from the Executive; and

         WHEREAS, simultaneously with its execution of this Agreement, the
Company is entering into an Agreement and Plan of Merger (the "Merger
Agreement") with T&H Acquisition Company ("Newco") and Tokos Medical
Corporation (Delaware) ("TM"), pursuant to which the Company and TM will merge
with and into Newco (the "Surviving Company") (such transaction shall hereafter
be referred to as the "Merger"), and such Merger will constitute a Change in
Control within the meaning of the Prior Agreement and as defined herein; and

         WHEREAS, TM's willingness to execute the Merger Agreement is
conditioned on Executive entering into the restrictive covenants contained in
this Agreement, and the parties hereto acknowledge the reasonableness of such
covenants, given the significant value that Executive will receive, directly
and indirectly, as a result of the Merger and given the payments to be made to
Executive pursuant to this Agreement in consideration of these covenants; and

         WHEREAS, the Board of Directors of the Company has determined that it
is appropriate to reinforce and encourage the continued attention and
dedication of members of the Company's management, including the Executive, to
their assigned duties without distraction in potentially disturbing
circumstances arising from the Merger or any subsequent Change in Control; and

         WHEREAS, the severance benefits payable by the Company to Executive as
provided herein are in part intended to ensure that Executive receives
reasonable
<PAGE>   2

compensation given the specific circumstances of Executive's employment history
with the Company; and

         WHEREAS, it is intended that neither this Agreement nor the Merger
shall diminish or waive in any way the rights of the Executive under the Prior
Agreement, which, as amended by this Agreement, shall continue to be applicable
to Executive's employment by the Surviving Company after the Merger;

         NOW, THEREFORE, in consideration of their respective obligations to
one another set forth in this Agreement, and other good and valuable
consideration, the receipt, sufficiency and adequacy of which the parties
hereby acknowledge, the parties to this Agreement, intending to be legally
bound, hereby agree as follows:

         1.      Term.

                 (a)  This Agreement shall become effective immediately prior
to the Effective Time of the Merger (as defined in Section 2.2 of the Merger
Agreement), provided that the Executive is still employed by the Company at
such time.  If the Merger does not become effective on or before May 31, 1996
or the Executive is not employed by the Company at the Effective Time, then
this Agreement shall be deemed never to have been in effect, and the Prior
Agreement shall remain in effect, unamended by this Agreement.

                 (b)  This Agreement shall terminate, except to the extent that
any obligation of the Company hereunder remains unpaid as of such time, upon
the earliest of (i) three years after the Effective Time if a Change in Control
(other than the Merger) has not occurred after the Effective Time; (ii) the
Date of Termination of the Executive based on death, Disability (as defined in
Section 3(b)), Retirement (as defined in Section 3(c)) or Cause (as defined in
Section 3(d)) or by the Executive other than for Good Reason (as defined in
Section 3(e)); or (iii) three years from the date of a Change in Control (as
defined in Section 2) occurring after the Merger if the Executive's employment
with the Company has not terminated as of such time.

         2.      Change in Control.  For purposes of this Agreement, a Change
in Control shall be deemed to have occurred if (a) there shall be consummated
(i) any consolidation or merger of the Company in which the Company is not the
continuing or surviving corporation or pursuant to which shares of the
Company's common stock would be converted into cash, securities or other
property, other than a merger of the Company in which the holders of the
Company's common stock immediately prior to the merger have the same
proportionate ownership of common stock of the surviving corporation
immediately after the merger, or (ii) any sale, lease, exchange or other
transfer (in one

transaction or a series of related transactions) of all, or substantially all,
of the assets of the Company, or (b) the stockholders of the Company approve
any plan or proposal for the liquidation or dissolution of the Company, or (c)
any person (as such term is used in Sections 13(d) and 14(d)(2) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act")), shall become
the beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act)
of 30% of the Company's outstanding Common Stock, or (d) during any period of
two consecutive years, individuals who at the beginning of such period
constitute the entire Board of Directors of the Company shall cease for any
reason to constitute a majority thereof unless the election, or the nomination
for election by the Company's stockholders, of each new director was approved
by a vote of at least two-thirds of the directors then still in office who were
directors at the beginning of the period; provided, however, that, in the
absence of a majority vote of the directors specified in subsection (d) of this
Section 2 to the contrary, the sale, lease, exchange or other disposition (in
one transaction or a series of related transactions) of less than 70% of the
total fair market value of all of the assets of the Company immediately prior
to such transaction or transactions shall not be deemed to be a Change in
Control and provided further that the transaction or transactions which involve
the sale, lease, exchange or other disposition of 70% or more of the total fair
market value of all of the assets of the Company immediately prior to such
transaction or transactions shall be deemed to be a Change in Control even if
approved by the Board of Directors of the Company.

         3.      Termination Following Change in Control.

                 (a)      If the Executive is still an employee of the Company

Executive shall be entitled to the compensation and benefits provided in
Section 4 upon the subsequent termination of the Executive's employment with
the Company by the Executive or by the Company during the term of this
Agreement, unless such termination is as a result of (i) the Executive's death;
(ii) the Executive's Disability; (iii) the Executive's Retirement; (iv) the
Executive's termination by the Company for Cause; or (v) the Executive's
decision to terminate employment other than for Good Reason.

                 (b)      Disability.  The term "Disability" as used in this
Agreement shall mean termination of the Executive's employment by the Company
as a result of the Executive's incapacity due to physical or mental illness,
provided that the Executive shall have been absent from his duties with the
Company on a full-time basis for six consecutive months and such absence shall
have continued unabated for 30 days after Notice of Termination as described in
Section 3(f) is thereafter given to the Executive by the Company.

                 (c)      Retirement.  The term "Retirement" as used in this
Agreement shall mean termination of the Executive's employment by the Company
based on the Executive's having attained age 65 or such later retirement age as
shall have been established pursuant to a written agreement between the Company
and the Executive.  Termination of Executive's employment at a time when
Executive is eligible to receive benefits under the Company's Retirement
Benefit Award or the Company's Protective Umbrella for Lifelong Security of
Employees Program shall not constitute Retirement unless Executive shall have
attained such age.

                 (d)      Cause.  The term "Cause" for purposes of this
Agreement shall mean the Company's termination of the Executive's employment on
the basis of criminal or civil fraud on the part of the Executive involving a
material amount of funds of the Company.  Notwithstanding the foregoing, the
Executive shall not be deemed to have been terminated for Cause unless and
until there shall have been delivered to the Executive a copy of a resolution
duly adopted by the affirmative vote of not less than three-quarters of the
entire membership of the Company's Board of Directors at a meeting of the Board
called and held for such purpose (after reasonable notice to the Executive and
an opportunity for the Executive, together with the Executive's counsel, to be
heard before the Board) finding that in the good faith opinion of the Board the
Executive was guilty of conduct set forth in the first sentence of this Section
3(d) and specifying the particulars thereof in detail.  For purposes of this
Agreement only, the preparation and filing of fictitious, false or misleading
claims in connection with any federal, state or other third party medical
reimbursement program, or any other violation of any rule or regulation in
respect of any federal, state or other third party medical reimbursement
program by the Company or any subsidiary of the Company shall not be deemed to
constitute "criminal fraud" or "civil fraud".

                 (e)      Good Reason.  For purposes of this Agreement, "Good
Reason" shall mean any of the following actions taken by the Company without
the Executive's express written consent:

                          (i) The assignment to the Executive by the Company of
duties inconsistent with, or the reduction of the powers and functions
associated with, the Executive's position, duties, responsibilities and status
with the Company prior to a Change in Control, or an adverse change in the
Executive's titles or offices as in effect prior to a Change in Control, or any
removal of the Executive from or any failure to re-elect the Executive to any
of such positions, except in connection with the termination of his employment
for Disability, Retirement or Cause or as a result of the Executive's death or
by the Executive other than for Good Reason;

<PAGE>   5

                          (ii) A reduction by the Company in the Executive's
base salary as in effect on the date hereof or as the same may be increased
from time to time during the term of this Agreement or the Company's failure to
increase (within 12 months of the Executive's last increase in base salary) the
Executive's base salary after a Change in Control in an amount which at least
equals, on a percentage basis, the average annual percentage increase in base
salary for all corporate officers of the Company effected in the preceding 36
months;

                          (iii) Any failure by the Company to continue in
effect any benefit plan, program or arrangement (including, without limitation,
any profit sharing plan, group annuity contract, group life insurance
supplement, or medical, dental, accident and disability plans) in which the
Executive was eligible to participate at the time of a Change in Control (or
any other plans providing the Executive with substantially similar benefits)
(hereinafter referred to as "Benefit Plans"), or the taking of any action by
the Company which would adversely affect the Executive's participation in or
materially reduce the Executive's benefits under any such Benefit Plan or
deprive the Executive of any fringe benefit enjoyed by the Executive at the
time of a Change in Control;

                          (iv) Any failure by the Company to continue in effect
any incentive plan or arrangement (including, without limitations, any bonus or
contingent bonus arrangements and credits and the right to receive performance
awards and similar incentive compensation benefits) in which the Executive is
participating at the time of a Change in Control (or any other plans or
arrangements providing him with substantially similar benefits) (hereinafter
referred to as "Incentive Plans") or the taking of any action by the Company
which would adversely affect the Executive's participation in any such
Incentive Plan or reduce the Executive's benefits under any such Incentive
Plan, expressed as a percentage of his base salary, by more than five
percentage points in any fiscal year as compared to the immediately preceding
fiscal year, or any action to reduce Executive's bonuses under any Incentive
Plan by more than 20% of the average annual bonus previously paid to Executive
with respect to the preceding three fiscal years;

                          (v) Any failure by the Company to continue in effect

without limitation, the Company's 1981 Incentive Stock Option Plan, 1983
Incentive Stock Option Plan, 1984 Nonqualified Stock Option Plan, 1985
Nonqualified Stock Option Plan, 1991 Stock Option Plan and 1993 Stock Option
Plan, Employee Stock Purchase Plan and any other plan or arrangement to receive
and exercise stock options, stock appreciation rights, restricted stock or
grants thereof) in which the Executive is participating or has the right to
participate in prior to a Change in Control (or plans or arrangements providing
him with substantially similar benefits) (hereinafter referred to as
"Securities Plans") or the taking of any action by the Company which would
adversely affect the Executive's

participation in or materially reduce the Executive's benefits under any such

                          (vii) Any failure by the Company to provide the

employment which is not effected pursuant to a Notice of Termination satisfying
the requirements of Section 3(f), and for purposes of this Agreement, no such
purported termination shall be effective; or

                          (xi) Any proposal or request by the Company after the
Effective Date to require that the Executive enter into a non-competition
agreement with the Company where the terms of such agreement as to its scope or
duration are greater than the terms set forth in Section 5 hereof.

Executive's employment by the Company for a reason specified in Section 3(b),

Agreement, a "Notice of Termination" shall mean a written notice which shall
indicate whether such termination is for the reason set forth in Section 3(b),

employment under the provision so indicated.  For purposes of this Agreement,
no termination of the





                                      -6-
<PAGE>   7

Executive's employment by the Company shall constitute a termination for
Disability, Retirement or Cause unless such termination is preceded by a Notice
of Termination.

                 (g)      Date of Termination.  "Date of Termination" shall
mean (a) if the Executive's employment is terminated by the Company for
Disability, 30 days after a Notice of Termination is given to the Executive
(provided that the Executive shall not have returned to the performance of the
Executive's duties on a full-time basis during such 30-day period) or (b) if
the Executive's employment is terminated by the Company or the Executive for
any other reason, the date on which the Executive's termination is effective;
provided that, if within 30 days after any Notice of Termination is given to
the Executive by the Company the Executive notifies the Company that a dispute
exists concerning the termination, the Date of Termination shall be the date
the dispute is finally determined whether by mutual agreement by the parties or
upon final judgment, order or decree of a court of competent jurisdiction (the
time for appeal therefrom having expired and no appeal having been perfected).

         4.      Compensation and Benefits upon Termination of Employment.

                 (a)      If the Company shall terminate the Executive's
employment after a Change in Control other than pursuant to Section 3(b), 3(c)
or 3(d) and Section 3(f), or if the Executive shall terminate his employment
for Good Reason, then the Company shall pay to the Executive, as severance
compensation and in consideration of the Executive's adherence to the terms of
Section 5 hereof, the following:

                          (1)     On the Date of Termination, the Company shall
become liable to the Executive for an amount equal to three times the
Executive's average annual compensation from the Company (as reported on Form
W-2 pursuant to applicable provisions of the Internal Revenue Code of 1986, as
amended (the "Code")) for the five years ending prior to the Date of
Termination, which amount shall be paid to the Executive in cash on or before
the fifth day following the Date of Termination.

                          (2)     For a period of three years following the
Date of Termination, the Executive and anyone entitled to claim under or
through the Executive shall be entitled to all benefits under the group
hospitalization plan, health care plan, dental care plan, life or other
insurance or death benefit plan, or other present or future similar group
employee benefit plan or program of the Company for which key executives are
eligible at the date of a Change in Control, to the same extent as if the
Executive had continued to be an employee of the Company during such period and
such benefits shall, to the extent not fully paid under any such plan or
program, be paid by the Company.





                                      -7-
<PAGE>   8

                          (3)     For a period of three years after the Date of
Termination, the Company shall allow the Executive to utilize for his business
and personal use any Company leased automobile previously furnished to him or
an equivalent type and style of automobile and shall reimburse the Executive
for the maintenance and repair costs of such automobile and extend full
insurance coverage relating to such automobile in favor of the Executive, as
additional named insured, during such three-year period.  In addition, the
Executive shall be entitled, at the Executive's sole discretion, to exercise
any option to acquire such automobile pursuant to the terms which may be
provided in the lease agreement for the automobile in question.

                 (b)      The parties hereto agree that the payments provided
in Section 4(a) hereof are reasonable compensation in light of the Executive's
services rendered to the Company and in consideration of the Executive's
adherence to the terms of Section 5 hereof.  Neither party shall contest the
payment of such benefits as constituting an "excess parachute payment" within
the meaning of Section 280G(b)(1) of the Code.  In the event that the Executive
becomes entitled to the compensation and benefits described in Section 4(a)
hereof (the "Compensation Payments") and the Company has determined, based upon
the advise of tax counsel selected by the Company's independent auditors and
acceptable to the Executive, that, as a result of such Compensation Payments
and any other benefits or payments required to be taken into account under Code
Section 280G(b)(2) ("Parachute Payments"), any of such Parachute Payments must
be reported by the Company as "excess parachute payments" and are therefore not
deductible by the Company, the Company shall pay to the Executive at the time
specified in Section 4(a) above an additional amount (the "Gross-Up Payment")
such that the net amount retained by the Executive, after deduction of any of
the tax imposed on the Executive by Section 4999 of the Code (the "Excise Tax")
and any Federal, state and local income tax and Excise Tax upon the Gross-Up
Payment, shall be equal to the Parachute Payments determined prior to the
application of this paragraph.  The value of any non-cash benefits or any
deferred payment or benefit shall be determined by the Company's independent
auditors.  For purposes of determining the amount of the Gross-Up Payment, the
Executive shall be deemed to pay Federal income taxes at the highest marginal
rate of Federal income taxation in the calendar year in which the Gross-Up
Payment is to be made and state and local income taxes at the highest marginal
rates of taxation in the state and locality of the Executive's residence on the
Date of Termination, net of the maximum reduction in Federal income taxes which
could be obtained from deduction of such state and local taxes.  In the event
that the Excise Tax payable by the Executive is subsequently determined to be
less than the amount, if any, taken into account hereunder at the time of
termination of the Executive's employment, the Executive shall repay to the
Company at the time that the amount of such reduction in Excise Tax is finally
determined the portion of the Gross-Up Payment attributable to such reduction
plus interest on the amount of such repayment at the rate provided for in
Section 1274(b)(2)(B)





                                      -8-
<PAGE>   9

of the Code ("Repayment Amount").  In the event that the Excise Tax payable by
the Executive is determined to exceed the amount, if any, taken into account
hereunder at the time of the termination of the Executive's employment
(including by reason of any payment the existence or amount of which cannot be
determined at the time of the Gross-Up Payment), the Company shall make an
additional Gross-Up Payment in respect of such excess (plus any interest and
penalty payable with respect to such excess) immediately prior to the time that
the amount of such excess is required to be paid by Executive ("Additional
Gross-up"), such that the net amount retained by the Executive, after deduction
of any Excise Tax on the Parachute Payments and any Federal, state and local
income tax and Excise Tax upon the Additional Gross-Up Payment, shall be equal
to the Parachute Payments determined prior to the application of this
paragraph.  The obligation to pay any Repayment Amount or Additional Gross-up
shall remain in effect under this Agreement for the entire period during which
the Executive remains liable for the Excise Tax, including the period during
which any applicable statute of limitation remains open.

                 (c)      The payments provided in Section 4(a) above shall be
in lieu of any other severance compensation otherwise payable to Executive
under the Company's established severance compensation policies; provided,
however, that nothing in this Agreement shall affect or impair Executive's
vested rights under any other employee benefit plan or policy of the Company.

                 (d)      Unless the Company determines that any Parachute
Payments made hereunder must be reported as "excess parachute payments" in
accordance with the third sentence of Section 4(b) above, neither party shall
file any return taking the position that the payment of such benefits
constitutes an "excess parachute payment" within the meaning of Section
280G(b)(1) of the Code.  If the Internal Revenue Service proposes an assessment
of Excise Tax against the Executive in excess of the amount, if any, taken into
account at the time specified in Section 4(a), then, if the Company notifies
Executive in writing that the Company elects to contest such assessment at its
expense, unless the Executive waives the right to an Additional Gross-Up
Payment, the Executive (i) shall in good faith cooperate with the Company in
contesting such proposed assessment; and (ii) such Executive shall not settle
such contest without the written consent of the Company.  Any such contest
shall be controlled by the Company, provided, however, that the Executive may
participate in such contest.

Competitive Position solely because of (y) Executive's position as a director
or holder of more than one percent (1%) of the outstanding stock of HTI or HIE,
if Executive had such position at the Effective Time or (z) Executive's
services for a Competing Business that are not directly related to the sale of

                          (vi)    "Restricted Territory" shall mean a one
hundred fifty (150) mile radius of the currently existing Company locations
listed on Schedule A, all of which are locations from which the Company
Products are developed, produced, marketed, sold or distributed.  The Executive
agrees to sign any amendment to Schedule A proposed by the Company, which
amendment adds or deletes Company locations so that Schedule A accurately
reflects all then current Company locations from which the Company's products
or services are developed, marketed, sold or provided.

                 (b)      Limitation on Competition  Ancillary to and as a
condition precedent to the Merger, in connection with which the Executive will
receive, both directly and indirectly, significant benefits and value, and in
consideration of the Covenant Payments payable by the Company to the Executive

Executive will not, without the prior written consent of the Company, anywhere
within the Restricted Territory, either directly or indirectly, alone or in
conjunction with any other party, accept, enter into or take any action in
conjunction with or in furtherance of a Competitive Position (other than action
to reject an unsolicited offer of a Competitive Position).

                 (c)      Limitation on Soliciting Customers  Ancillary to and

will receive, both directly and indirectly, significant benefits and value, and

                                      -11-
<PAGE>   12

Covenant Payments payable by the Company to the Executive under this Agreement,
the Executive agrees that during the Covenant Period, the Executive will not,
without the prior written consent of the Company, alone or in conjunction with
any other party, solicit, divert or appropriate or attempt to solicit, divert
or appropriate on behalf of a Competing Business with which Executive has a
Competitive Position any Customer located in the Restricted Territory (or any
other Customer with which the Executive had any direct contact on behalf of the
Company) for the purpose of providing the Customer or having the Customer
provided with a Competing Product or Competing Service.

                 (d)      Limitation on Soliciting Personnel or Other Parties

which the Executive will receive, both directly and indirectly, significant
benefits and value, and in consideration of the Covenant Payments payable by
the Company to the Executive under this Agreement, the Executive hereby agrees
that he will not, without the prior written consent of the Company, alone or in
conjunction with any other party, solicit or attempt to solicit any employee,
consultant, contractor, independent broker or other personnel of the Company to
terminate, alter or lessen that party's affiliation with the Company or to
violate the terms of any agreement or understanding between such employee,
consultant, contractor or other person and the Company.

                 (e)      Acknowledgement  The parties acknowledge and agree
that the covenants of the Executive in Subsection (b) through (d) are and shall
be treated, under law, as "ancillary to the sale of the Company's business."
The parties acknowledge and agree that the Protective Covenants are reasonable
as to time, scope and territory given the Company's need to protect its trade
secrets and confidential business information and given the substantial
payments and benefits to which the Executive is entitled in connection with the
Merger and otherwise pursuant to this Agreement.

                 (f)      Remedies  The parties acknowledge that any breach or
threatened breach of a Protective Covenant by the Executive is reasonably
likely to result in irreparable injury to the Company, and therefore, in
addition to all remedies provided at law or in equity, the Executive agrees
that the Company shall be entitled to a temporary restraining order and a
permanent injunction to prevent a breach or contemplated breach of the
Protective Covenant.  If the Company seeks an injunction, the Executive waives
any requirement that the Company post a bond or any other security.

         6.      No Obligation to Mitigate Damages; No Effect on Other 
Contractual Rights.

                 (a)      All compensation and benefits provided to the
Executive under this Agreement are in consideration of the Executive's services
rendered to the Company and





                                      -12-

Executive shall not be required to mitigate damages or the amount of any
payment provided for under this Agreement by seeking other employment or
otherwise, nor shall the amount of any payment provided for under this
Agreement be reduced by any compensation earned by the Executive as the result
of employment by another employer after the Date of Termination, or otherwise.

                 (b)      The provisions of this Agreement, and any payment
provided for hereunder, shall not reduce any amounts otherwise payable, or in
any way diminish the Executive's existing rights, or rights which would accrue
solely as a result of the passage of time, under any Benefit Plan, Incentive
Plan or Securities Plan, employment agreement or other contract, plan or
arrangement.

         7.      Successor to the Company.

                 (a)      The Company will require any successor or assign
(whether direct or indirect, by purchase, merger, consolidation or otherwise)
to all or substantially all of the business and/or assets of the Company, by
agreement in form and substance satisfactory to the Executive, expressly,
absolutely and unconditionally to assume and agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform it if no such succession or assignment had taken place.  Any failure of
the Company to obtain such agreement prior to the effectiveness of any such
succession or assignment shall be a material breach of this Agreement and shall
entitle the Executive to terminate the Executive's employment for Good Reason.
As used in this Agreement, "Company" shall mean the Company as hereinbefore
defined and any successor or assign to its business and/or assets as aforesaid,
including without limitation, the Surviving Company in the Merger.  If at any
time during the term of this Agreement the Executive is employed by any
corporation a majority of the voting securities of which is then owned by the
Company, "Company" as used in Sections 3, 4, 12 and 14 hereof shall in addition
include such employer.  In such event, the Company agrees that it shall pay or
shall cause such employer to pay any amounts owed to the Executive pursuant to
Section 4 hereof.

                 (b)      This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal and legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees.  If the
Executive should die while any amounts are still payable to him or her
hereunder, all such amounts, unless otherwise provided herein, shall be paid in
accordance with the terms of this Agreement to the Executive's devisee,
legatee, or the designee or, if there be no such designee, to the Executive's
estate.

                          Marietta, Georgia 30067

                 If to Executive:

                          J. Paul Yokubinas
                          210 Lakeside Drive

or such other address as either party may have furnished to the other in
writing in accordance herewith, except that notices of change of address shall
be effective only upon receipt.

         9.      Miscellaneous.  No provisions of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in writing signed by the Executive and the Company.  No waiver by
either party hereto at any time of any breach by the other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed
by such other party shall be deemed a waiver of similar or dissimilar
provisions or conditions at the same or at any prior or subsequent time.
Neither this Agreement nor the Merger shall diminish or waive in any way the
rights of Executive under the Prior Agreement, which as amended by this
Agreement, shall continue to be applicable to Executive's employment by the
Surviving Company after the Merger.  No agreements or representations, oral or
otherwise, express or implied, with respect to the subject matter hereof have
been made by either party which are not set forth expressly in this Agreement.
This Agreement shall be governed by and construed in accordance with the laws
of the State of Georgia.

         10.     Validity.  The invalidity or unenforceability of any
provisions of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, which shall remain in full force and
effect.

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

         12.     Legal Fees and Expenses.  The Company shall pay all legal
fees, expenses and damages which the Executive may incur as a result of the
Executive's instituting legal action to enforce his rights hereunder, or in the
event the Company contests the validity, enforceability or the Executive's
interpretation of, or determinations under, this Agreement.  If the Executive
is the prevailing party or recovers any damages in such legal action, the
Executive shall be entitled to receive in addition thereto pre-judgment and
post-judgment interest on the amount of such damages.

         13.     Severability, Modification.  All provisions of this Agreement
are severable from one another, and the unenforceability or invalidity of any
provision of this Agreement shall not affect the validity or enforceability of
the remaining provisions of this Agreement, but such remaining provisions shall
be interpreted and construed in such a manner as to carry out fully the
intention of the parties.  Should any judicial body interpreting this Agreement
deem any provision of this Agreement to be unreasonably broad in time,
territory, scope or otherwise, it is the intent and desire of the parties that
such judicial body, to the greatest extent possible, reduce the breadth of such
provision to the maximum legally allowable parameters rather than deeming such
provision totally unenforceable or invalid.

         14.     Confidentiality.  The Executive acknowledges that he or she
has previously entered into, and continues to be bound by the terms of, a
Confidentiality Agreement with the Company.

         15.     Agreement Not an Employment Contract.  This Agreement shall
not be deemed to constitute or be deemed ancillary to an employment contract
between the Company and the Executive, and nothing herein shall be deemed to
give the Executive the right to continue in the employ of the Company or to
eliminate the right of the Company to discharge the Executive at any time.
