                                  INTRODUCTION

    Company  N Merger Corp.,  a New Jersey  corporation (the "Purchaser") wholly
owned by W. R. Grace & Co., a New York corporation ("Parent"), hereby offers  to
purchase all outstanding shares of Common Stock, no par value (the "Shares"), of
Home  Nutritional Services, Inc.,  a New Jersey  corporation (the "Company"), at
$7.85 per Share, net to  the seller in cash, upon  the terms and subject to  the
conditions  set forth  in this Offer  to Purchase  and in the  related Letter of
Transmittal (which together  constitute the  "Offer"). The Offer  is being  made
pursuant  to an  Agreement and Plan  of Merger, dated  as of March  4, 1994 (the
"Merger Agreement"), by and among the  Company, Parent and the Purchaser,  which
provides,  among  other  things, for  the  making  of the  Offer  and, following
consummation of the Offer and the satisfaction or waiver of certain  conditions,
the  merger of the Purchaser with and  into the Company (the "Merger"), with the
Company surviving the Merger as a wholly owned subsidiary of Parent.

    THE BOARD OF DIRECTORS  OF THE COMPANY, BY  UNANIMOUS VOTE OF THE  DIRECTORS
PRESENT,   HAS  DETERMINED  THAT  THE  MERGER  AGREEMENT  AND  THE  TRANSACTIONS
CONTEMPLATED THEREBY, INCLUDING THE OFFER AND THE MERGER, ARE FAIR TO AND IN THE
BEST INTEREST OF THE  COMPANY AND ITS SHAREHOLDERS,  HAS APPROVED THE OFFER  AND
THE  MERGER, AND RECOMMENDS THAT THE COMPANY'S SHAREHOLDERS ACCEPT THE OFFER AND
TENDER THEIR SHARES PURSUANT TO THE OFFER.

    HEALTHDYNE, INC. ("HEALTHDYNE"), THE  BENEFICIAL OWNER OF 7,800,000  SHARES,
CONSTITUTING  APPROXIMATELY  66% OF  THE FULLY  DILUTED SHARES  (THE "HEALTHDYNE
SHARES"), HAS AGREED, UPON THE  TERMS AND SUBJECT TO  THE CONDITIONS OF A  STOCK
PURCHASE  AGREEMENT DATED AS  OF MARCH 4, 1994,  AMONG HEALTHDYNE, THE PURCHASER
AND PARENT  (THE  "STOCK  PURCHASE  AGREEMENT"), TO  SELL  SUCH  SHARES  TO  THE
PURCHASER  AND TO TENDER AND SELL SUCH SHARES PURSUANT TO THE OFFER. SEE SECTION
12.

    DILLON, READ & CO., INC. ("DILLON, READ"), FINANCIAL ADVISOR TO THE COMPANY,
HAS DELIVERED TO THE BOARD  OF DIRECTORS OF THE  COMPANY ITS WRITTEN OPINION  TO
THE  EFFECT THAT THE CONSIDERATION  TO BE RECEIVED BY  THE HOLDERS OF THE SHARES
PURSUANT TO EACH OF THE  OFFER AND THE MERGER IS  FAIR TO THE HOLDERS OF  SHARES
(OTHER  THAN PARENT AND ITS SUBSIDIARIES) FROM A FINANCIAL POINT OF VIEW. A COPY
OF THE  OPINION OF  DILLON, READ  IS CONTAINED  IN THE  COMPANY'S  SOLICITATION/
RECOMMENDATION  STATEMENT  ON SCHEDULE  14D-9 (THE  "SCHEDULE 14D-9"),  WHICH IS
BEING  MAILED  TO  SHAREHOLDERS  TOGETHER  WITH  THIS  OFFER  TO  PURCHASE,  AND
SHAREHOLDERS  ARE URGED TO READ THE OPINION IN ITS ENTIRETY FOR A DESCRIPTION OF
THE ASSUMPTIONS  MADE, FACTORS  CONSIDERED AND  PROCEDURES FOLLOWED  BY  DILLON,
READ. SEE SECTION 11.

    In  connection with the Offer and  the Merger, Healthdyne has announced that
it has abandoned its proposed exchange  offer for 2,150,000 Shares announced  on
January 6, 1994 (the "Exchange Offer"). See Section 11.

    The  Offer is subject, among other  things, to satisfaction of the condition
(the "Minimum  Condition")  that  either  there  be  validly  tendered  and  not
withdrawn  prior to  the Expiration  Date (as defined  in Section  1 below) that
number of  Shares (the  "Minimum  Number of  Shares")  representing at  least  a
majority of all outstanding Shares, assuming the exercise in full of all options
with  exercise  prices of  less than  $7.85 per  Share and  the issuance  of the
maximum number of Shares  issuable under the  Company's Employee Stock  Purchase
Plan ("Fully Diluted Shares"), or all of the conditions to the closing under the
Stock  Purchase Agreement  shall have been  satisfied or  irrevocably waived and
Healthdyne, Parent and the Purchaser shall have confirmed that the  transactions
contemplated  thereunder,  including the  sale by  Healthdyne of  the Healthdyne
Shares, will close immediately after consummation of the Offer.

                                       3
<PAGE>
    PURSUANT TO  THE  TERMS OF  THE  STOCK  PURCHASE AGREEMENT  AND  SUBJECT  TO
CONDITIONS  CONTAINED THEREIN, THE PURCHASER HAS  THE RIGHT (WHICH IT INTENDS TO
EXERCISE) TO REQUIRE HEALTHDYNE TO TENDER THE HEALTHDYNE SHARES INTO THE  OFFER,
IN  WHICH  CASE  THE  MINIMUM CONDITION  WOULD  BE  MET. SEE  SECTION  14  FOR A
DESCRIPTION OF OTHER CONDITIONS TO THE OFFER.

    According to the  Merger Agreement,  as of March  4, 1994,  the Company  had
issued  and  outstanding  11,546,232  Shares and  outstanding  stock  options to
purchase an  aggregate  of 881,470  Shares  (the "Options")  granted  under  the
Company's  1989 Stock  Option Plan and  1989 Non-Employee  Director Stock Option
Plan (the "Stock Option Plans"). According to the Company, 336,135 of the Shares
issuable upon exercise of the Options are included in Fully Diluted Shares  (the
"Option  Shares").  In addition,  according  to the  Merger  Agreement, up  to a
maximum of 10,000 Shares (the "Plan Shares")  are issuable by the Company on  or
prior  to March 31, 1994  under the Company's Employee  Stock Purchase Plan (the
"Stock Purchase Plan"); the Plan Shares are included in Fully Diluted Shares. In
the Merger Agreement, the Company has  agreed to terminate or suspend the  Stock
Purchase Plan on or prior to March 31, 1994.

    Based  on the foregoing,  and assuming the issuance  prior to the Expiration
Date of all the Option Shares and  the Plan Shares, the number of Fully  Diluted
Shares  would be 11,892,367 and the Minimum Number of Shares would be 5,946,184.
The Purchaser reserves the  right (but shall not  be obligated), subject to  the
rules   and  regulations  of   the  Securities  and   Exchange  Commission  (the
"Commission"), to waive  or amend the  Minimum Condition and  to purchase  fewer
than the Minimum Number of Shares pursuant to the Offer. See Section 1.

    The  Merger  Agreement  provides that  the  Offer  (or the  purchase  of the
Healthdyne Shares pursuant to  the Stock Purchase Agreement)  will be the  first
step in the Purchaser's acquisition of all the outstanding Shares. Subsequent to
the consummation of the Offer (or the purchase of the Healthdyne Shares pursuant
to the Stock Purchase Agreement), the Purchaser will be merged with and into the
Company  as  soon as  practicable following  the satisfaction  or waiver  of the
conditions to  the  Merger  (the  "Effective  Time").  Pursuant  to  the  Merger
Agreement,  each Share outstanding immediately prior  to the Effective Time will
be converted into  the right  to receive $7.85  net in  cash, without  interest.
Pursuant  to the Merger Agreement, the Company  has agreed not to declare or pay
any dividends on the Shares.  The Merger is subject  to a number of  conditions,
including  approval by shareholders of the Company, if such approval is required
by the  New  Jersey Business  Corporation  Act  (the "NJBCA").  If  the  Minimum
Condition  is satisfied upon  the consummation of the  Offer, the Purchaser will
have sufficient voting power to approve the Merger without the affirmative  vote
of any other shareholder of the Company. In the event the Purchaser acquires 90%
or  more  of the  outstanding Shares  pursuant  to the  Offer or  otherwise, the
Purchaser would be able to effect the Merger pursuant to the "short-form" merger
provisions of the NJBCA, without  prior notice to, or  any action by, any  other
shareholder of the Company. See Section 12.

    Tendering  shareholders will not be  obligated to pay brokerage commissions,
solicitation fees or,  subject to Instruction  6 of the  Letter of  Transmittal,
stock  transfer taxes  on the sale  of Shares  to the Purchaser  pursuant to the
Offer. However, any tendering shareholder or  other payee who fails to  complete
and  sign the Substitute Form W-9 included with the Letter of Transmittal may be
subject to required backup  Federal income tax withholding  of 31% of the  gross
proceeds  payable to such shareholder or other  payee pursuant to the Offer. See
Section 2. The Purchaser will  pay the fees and  expenses of Chemical Bank  (the
"Depositary")  and D. F. King & Co., Inc. (the "Information Agent"), incurred in
connection with the Offer. For a description of the fees and expenses to be paid
by the Purchaser, see Section 16.

    THIS OFFER  TO PURCHASE  AND  THE LETTER  OF TRANSMITTAL  CONTAIN  IMPORTANT
INFORMATION  THAT SHAREHOLDERS  ARE URGED  TO READ  CAREFULLY BEFORE  MAKING ANY
DECISION WITH RESPECT TO THE OFFER.

    1.  TERMS OF THE OFFER.  Upon the terms and subject to the conditions of the
Offer (including, if the Offer is extended or amended, the terms and  conditions
of  any extension or amendment), the Purchaser  will accept for payment, and pay
for,  all   Shares   that   are   validly  tendered   on   or   prior   to   the

                                       4
<PAGE>
Expiration  Date  and  not withdrawn  in  accordance  with Section  3.  The term
"Expiration Date" means 12:00 Midnight, New York City time, on Wednesday,  April
6,  1994, unless  and until  the Purchaser, in  its sole  discretion, shall have
extended the period of time during which  the Offer is open, in which event  the
term  "Expiration Date" shall mean the latest  time and date on which the Offer,
as so extended by the Purchaser, shall expire.

    Subject to the applicable  rules and regulations of  the Commission and  the
terms  of the Merger  Agreement, the Purchaser expressly  reserves the right, in
its sole  discretion, at  any time  and from  time to  time, and  regardless  of
whether  or not  any of  the events set  forth in  Section 14  hereof shall have
occurred or shall have been determined by the Purchaser to have occurred, to (a)
extend the period  of time  during which  the Offer  is open  and thereby  delay
acceptance  for payment of, and  the payment for, any  Shares, by giving oral or
written notice of such extension  to the Depositary and  (b) amend the Offer  in
any  respect  by  giving  oral  or  written  notice  of  such  amendment  to the
Depositary. The Purchaser shall not have  any obligation to pay interest on  the
purchase  price for tendered Shares, whether  or not the Purchaser exercises its
right to extend the Offer.

    If by 12:00 Midnight, New  York City time, on  Wednesday, April 6, 1994  (or
any  other date or time the Offer is scheduled to expire), any or all conditions
to the Offer have not been satisfied or waived, the Purchaser reserves the right
(but shall not be obligated), subject to the applicable rules and regulations of
the Commission and the terms of the Merger Agreement, to (a) decline to purchase
any of  the  Shares  tendered  and  terminate  the  Offer,  (b)  waive  all  the
unsatisfied  conditions  and, subject  to  complying with  applicable  rules and
regulations of the Commission, purchase all Shares validly tendered, (c)  extend
the Offer and, subject to the right of shareholders to withdraw Shares until the
Expiration  Date, retain the Shares that have been tendered during the period or
periods for which the Offer is extended or (d) amend the Offer.

    There can be  no assurance  that the Purchaser  will exercise  its right  to
extend  the Offer. Any  extension, amendment or termination  will be followed as
promptly as practicable  by public announcement.  In the case  of an  extension,
Rule  14e-1(d)  under  the Securities  Exchange  Act  of 1934,  as  amended (the
"Exchange Act"), requires  that the announcement  be issued no  later than  9:00
a.m.,  New  York  City time,  on  the  next business  day  after  the previously
scheduled  Expiration   Date  in   accordance  with   the  public   announcement
requirements  of Rule 14d-4(c) under the Exchange Act. Subject to applicable law
(including Rules 14d-4(c)  and 14d-6(d)  under the Exchange  Act, which  require
that  any  material  change  in  the information  published,  sent  or  given to
shareholders  in  connection  with  the   Offer  be  promptly  disseminated   to
shareholders  in a  manner reasonably  designed to  inform shareholders  of such
change), and without limiting  the manner in which  the Purchaser may choose  to
make any public announcement, the Purchaser shall have no obligation to publish,
advertise  or otherwise communicate  any such public  announcement other than by
making a  release to  the Dow  Jones  News Service.  As used  in this  Offer  to
Purchase,  "business day"  has the  meaning set  forth in  Rule 14d-1  under the
Exchange Act.

    If the Purchaser extends the Offer,  or if the Purchaser (whether before  or
after  its acceptance for  payment of Shares)  is delayed in  its purchase of or
payment for Shares or is unable to pay for Shares pursuant to the Offer for  any
reason,  then, without prejudice to the  Purchaser's rights under the Offer, the
Depositary may  retain tendered  Shares on  behalf of  the Purchaser,  and  such
Shares  may not  be withdrawn  except to  the extent  tendering shareholders are
entitled to withdrawal rights as described in Section 3. However, the ability of
the Purchaser to delay  the payment for Shares  that the Purchaser has  accepted
for payment is limited by Rule 14e-1 under the Exchange Act, which requires that
a  bidder pay the consideration offered or return the securities deposited by or
on behalf of holders of securities promptly after the termination or  withdrawal
of such bidder's offer.

    If  the Purchaser makes a  material change in the terms  of the Offer or the
information concerning the  Offer or waives  a material condition  of the  Offer
(including  a waiver of  the Minimum Condition),  the Purchaser will disseminate
additional tender offer materials and extend the Offer to the extent required by
Rules 14d-4(c), 14d-6(d) and  14e-1 under the Exchange  Act. The minimum  period
during

                                       5
<PAGE>
which  an offer must remain open following  material changes in the terms of the
offer or information concerning  the offer, other  than a change  in price or  a
change  in the percentage of  securities sought, will depend  upon the facts and
circumstances then existing, including the  relative materiality of the  changed
terms  or information. With respect to a  change in the percentage of securities
sought of more than 2% of the outstanding Shares or a change in price, a minimum
period of  10  business  days  is  generally  required  to  allow  for  adequate
dissemination to shareholders and investor response.

    Consummation  of  the  Offer is  conditioned  upon the  satisfaction  of the
Minimum Condition, the expiration or termination of all waiting periods  imposed
by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the
regulations  thereunder (the  "HSR Act") and  the other conditions  set forth in
Section 14 hereof. The Purchaser reserves the right (but shall not be obligated)
to waive any  or all  such conditions.  If the  Purchaser waives  or amends  the
Minimum Condition during the last five business days in which the Offer is open,
in  the  view of  the  Commission (with  which  the Purchaser  will  comply) the
Purchaser will be required to extend the  Offer so that it will remain open  for
at  least five business days after the  announcement of such waiver or amendment
is first published, sent or given to holders of Shares.

    The Company  has provided  to the  Purchaser its  list of  shareholders  and
security position listings for the purpose of disseminating the Offer to holders
of  Shares.  This Offer  to Purchase  and  the Letter  of Transmittal  and other
relevant materials will be mailed to  record holders of Shares and furnished  to
brokers,  dealers, commercial banks,  trust companies and  similar persons whose
names, or the names  of whose nominees,  appear on the  shareholder list or,  if
applicable,  who  are listed  as participants  in  a clearing  agency's security
position listings, for subsequent transmittal to beneficial owners of Shares.

    2.  PROCEDURE  FOR TENDERING  SHARES.  For  a shareholder  to tender  Shares
validly pursuant to the Offer, either (a) a properly completed and duly executed
Letter  of  Transmittal  (or  facsimile thereof),  with  any  required signature
guarantees and any other required documents, must be received by the  Depositary
at one of its addresses set forth on the back cover of this Offer to Purchase on
or  prior to the Expiration Date and either (i) certificates for tendered Shares
must be  received by  the  Depositary at  one of  such  addresses prior  to  the
Expiration  Date or (ii) Shares must be delivered pursuant to the procedures for
book-entry transfer set forth  below and a  Book-Entry Confirmation (as  defined
below)  must be received by  the Depositary prior to  the Expiration Date or (b)
the tendering shareholder  must comply with  the guaranteed delivery  procedures
set forth below.

    For  purposes of the Offer, within two  business days after the date of this
Offer to Purchase, the Depositary will establish an account with respect to  the
Shares at The Depository Trust Company, the Midwest Securities Trust Company and
the   Philadelphia  Depository  Trust  Company,  (each  a  "Book-Entry  Transfer
Facility" and collectively the "Book-Entry Transfer Facilities"). Any  financial
institution  that is a participant in any of the Book-Entry Transfer Facilities'
systems may make book-entry delivery of Shares by causing a Book-Entry  Transfer
Facility  to  transfer  such  Shares  into  the  Depositary's  account  at  such
Book-Entry  Transfer  Facility  in  accordance  with  that  Book-Entry  Transfer
Facility's procedure for such transfer. However, although delivery of Shares may
be  effected  through book-entry  transfer into  the  Depositary's account  at a
Book-Entry Transfer Facility, the Letter of Transmittal (or facsimile  thereof),
properly completed and duly executed, with any required signature guarantees and
any other required documents, must, in any case, be transmitted to, and received
by,  the Depositary at one of its addresses  set forth on the back cover of this
Offer to Purchase  prior to the  Expiration Date, or  the tendering  shareholder
must  comply  with  the  guaranteed  delivery  procedures  described  below. The
confirmation of a book-entry transfer of Shares into the Depositary's account at
a Book-Entry Transfer  Facility as described  above is referred  to herein as  a
"Book-Entry  Confirmation".  DELIVERY  OF  DOCUMENTS  TO  A  BOOK-ENTRY TRANSFER
FACILITY IN ACCORDANCE WITH SUCH BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES  DOES
NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.

    THE  METHOD OF DELIVERY OF SHARES AND ALL OTHER REQUIRED DOCUMENTS IS AT THE
ELECTION AND  RISK  OF  THE  TENDERING SHAREHOLDER.  IF  DELIVERY  IS  BY  MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.
IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

                                       6
<PAGE>
    No  signature guarantee is required on the  Letter of Transmittal (a) if the
Letter of Transmittal  is signed  by the  registered holder  of Shares  tendered
therewith  and such registered holder has  not completed either the box entitled
"Special  Payment   Instructions"  or   the  box   entitled  "Special   Delivery
Instructions"  on the Letter of  Transmittal or (b) if  such Shares are tendered
for the account of a firm that  is a member of a registered national  securities
exchange  or  of  the  National Association  of  Securities  Dealers,  Inc. (the
"NASD"), a commercial bank or trust company having an office or correspondent in
the United States or by any other "Eligible Guarantor Institution", as such term
is defined in Rule 17Ad-15 of the Exchange Act (each an "Eligible Institution").
In all other cases, all signatures on Letters of Transmittal must be  guaranteed
by  an  Eligible  Institution.  See  Instructions  1  and  5  to  the  Letter of
Transmittal. If the  certificates for  Shares are registered  in the  name of  a
person  other than the signer of the Letter  of Transmittal, or if payment is to
be made or certificates for Shares not accepted for payment are to be issued  to
a  person other than the registered  owner of the certificates surrendered, then
the certificates  for  Shares  tendered  must  be  endorsed  or  accompanied  by
appropriate  stock powers, in either case signed exactly as the name or names of
the registered owner or owners appear  on the certificates, with the  signatures
on  the certificates or stock powers  guaranteed as aforesaid. See Instruction 5
to the Letter of Transmittal.

    If a shareholder  desires to tender  Shares pursuant to  the Offer and  such
shareholder's  certificates  for Shares  are  not immediately  available  or the
procedures for book-entry transfer cannot be completed on a timely basis or time
will not permit all required  documents to reach the  Depositary on or prior  to
the  Expiration  Date, such  shareholder's  tender may  be  effected if  all the
following conditions are met:

        (a) such tender is made by or through an Eligible Institution;

        (b) a properly completed and duly executed Notice of Guaranteed Delivery
    substantially in  the form  provided by  the Purchaser  is received  by  the
    Depositary, as provided below, on or prior to the Expiration Date; and

        (c) the certificates for all physically tendered Shares, or a Book-Entry
    Confirmation  with respect  to all  Shares tendered  by book-entry transfer,
    together with a properly completed  and duly executed Letter of  Transmittal
    (or facsimile thereof), with any required signature guarantees and any other
    documents  required  by  the  Letter of  Transmittal,  are  received  by the
    Depositary within six  Nasdaq Stock Market  trading days after  the date  of
    execution of such Notice of Guaranteed Delivery.

    The Notice of Guaranteed Delivery may be delivered by hand to the Depositary
or transmitted by telegram, facsimile transmission or mail to the Depositary and
must  include a guarantee  by an Eligible  Institution in the  form set forth in
such Notice of Guaranteed Delivery.

    Notwithstanding any other provision hereof, payment for Shares accepted  for
payment  pursuant  to the  Offer will  in all  cases be  made only  after timely
receipt by the Depositary of certificates for, or a Book-Entry Confirmation with
respect to,  such Shares,  a  properly completed  and  duly executed  Letter  of
Transmittal  (or  facsimile thereof)  and any  other  documents required  by the
Letter of Transmittal. For purposes of  the Offer, the Purchaser will be  deemed
to have accepted for payment, and thereby purchased, Shares properly tendered to
the  Purchaser and  not withdrawn as,  if and  when the Purchaser  gives oral or
written notice to the  Depositary of the Purchaser's  acceptance for payment  of
such Shares.

    UNDER  NO  CIRCUMSTANCES WILL  INTEREST BE  PAID ON  THE PURCHASE  PRICE FOR
SHARES, REGARDLESS OF ANY  EXTENSION OF THE  OFFER OR ANY  DELAY IN MAKING  SUCH
PAYMENT.

    The valid tender of Shares pursuant to one of the procedures described above
will  constitute a binding  agreement between the  tendering shareholder and the
Purchaser upon the terms and subject to the conditions of the Offer.

    By executing the  Letter of Transmittal  as set forth  above, the  tendering
shareholder  will irrevocably  appoint designees of  the Purchaser,  and each of
them, as such shareholder's attorneys-in-fact and

                                       7
<PAGE>
proxies in the manner  set forth in  the Letter of  Transmittal, each with  full
power  of substitution,  to the  full extent  of such  shareholder's rights with
respect to the Shares tendered by  such shareholder and accepted for payment  by
the  Purchaser and with respect to any and all other Shares and other securities
or rights issued  or issuable in  respect of such  Shares on or  after March  4,
1994.  All such  proxies shall  be considered  coupled with  an interest  in the
tendered Shares. Such appointment will be effective when, and only to the extent
that, the Purchaser accepts for payment  Shares tendered by such shareholder  as
provided  herein. Holders of Shares who  tender Shares to the Purchaser pursuant
to the  Offer will  retain ownership  of the  economic benefits  of such  Shares
(i.e.,  dividends, voting rights, etc.) until such time as the Purchaser accepts
such Shares for payment pursuant to the Offer. Upon such appointment, all  prior
powers  of attorney and proxies  given by such shareholder  with respect to such
Shares or other securities or rights  will, without further action, be  revoked,
and  no subsequent powers of  attorney and proxies may  be given (and, if given,
will not be deemed  effective). The designees of  the Purchaser will thereby  be
empowered  to exercise all voting  and other rights with  respect to such Shares
and other securities or  rights in respect of  any annual, special or  adjourned
meeting  of the Company's shareholders, any consent  in lieu of any such meeting
or otherwise,  as they  in  their sole  discretion  deem proper.  The  Purchaser
reserves  the right to  require that, in  order for Shares  to be deemed validly
tendered, immediately  upon  the  Purchaser's acceptance  for  payment  of  such
Shares, the Purchaser must be able to exercise full voting and other rights with
respect  to such Shares and other securities  or rights, including voting at any
meeting of shareholders then scheduled.

    All questions  as to  the  validity, form,  eligibility (including  time  of
receipt)  and  acceptance of  any tender  of  Shares will  be determined  by the
Purchaser in  its sole  discretion,  and its  determination  will be  final  and
binding.  The Purchaser reserves the absolute right to reject any or all tenders
of any Shares that it  determines are not in proper  form or the acceptance  for
payment  of or payment for which may, in the opinion of the Purchaser's counsel,
be unlawful.  The  Purchaser  also  reserves the  absolute  right  in  its  sole
discretion  to  waive  any of  the  conditions of  the  Offer or  any  defect or
irregularity in the tender of any Shares of any particular shareholder,  whether
or  not  similar defects  or  irregularities are  waived  in the  case  of other
shareholders. None of  the Purchaser,  Parent, the  Depositary, the  Information
Agent  or any other  person will be under  any duty to  give notification of any
defects or irregularities in tenders or will incur any liability for failure  to
give  any such  notification. The  Purchaser's interpretation  of the  terms and
conditions of the Offer will be final and binding.

    Under Federal tax laws, the Depositary  will be required to withhold 31%  of
the  amount of any payments made to  certain shareholders pursuant to the Offer.
To avoid  such  Federal income  tax  backup  withholding with  respect  to  cash
received  by a shareholder  pursuant to the Offer,  a tendering shareholder must
provide the  Depositary  with  its correct  taxpayer  identification  number  or
certify  that he  is not  subject to  Federal income  tax backup  withholding by
completing the Substitute Form W-9 included with the Letter of Transmittal.  See
Instruction 10 and the information under the caption "Important Tax Information"
in the Letter of Transmittal.

    3.   WITHDRAWAL  RIGHTS.   Except as otherwise  provided in  this Section 3,
tenders of Shares are irrevocable. Shares tendered pursuant to the Offer may  be
withdrawn  pursuant to the procedures  set forth below at  any time prior to the
Expiration Date and, unless theretofore accepted for payment and paid for by the
Purchaser pursuant to the Offer, may also be withdrawn at any time after May  8,
1994.

    For a withdrawal to be effective, a written or facsimile transmission notice
of  withdrawal must be timely received by the Depositary at one of its addresses
set forth on the back cover of this Offer to Purchase. Such notice must  specify
the  name of the person  who tendered the Shares to  be withdrawn, the number of
Shares to be withdrawn and the name of the registered holder, if different  from
the  name of the person who tendered the Shares. If certificates for Shares have
been delivered or  otherwise identified to  the Depositary, then,  prior to  the
physical  release  of  such  certificates,  the  serial  numbers  shown  on such
certificates must  be submitted  to the  Depositary and  the signatures  on  the
notice of withdrawal must be guaranteed by an Eligible Institution, except, with
respect  to signature guarantees, in the case  of Shares tendered by an Eligible
Institution. If  Shares  have been  delivered  pursuant to  the  procedures  for
book-entry   transfer  set  forth  in  Section   2,  any  notice  of  withdrawal

                                       8
<PAGE>
must also  specify  the  name and  number  of  the account  at  the  appropriate
Book-Entry  Transfer Facility to be credited  with the withdrawn Shares and must
otherwise  comply   with  such   Book-Entry  Transfer   Facility's   procedures.
Withdrawals  of tenders of Shares may not  be rescinded, and any Shares properly
withdrawn will thereafter  be deemed not  validly tendered for  purposes of  the
Offer. However, withdrawn Shares may be retendered by again following one of the
procedures described in Section 2 at any time prior to the Expiration Date.

    All  questions as to  the form and  validity (including time  of receipt) of
notices  of  withdrawal  will  be  determined  by  the  Purchaser  in  its  sole
discretion,  and  its  determination will  be  final  and binding.  None  of the
Purchaser, Parent, the  Depositary, the  Information Agent or  any other  person
will  be under any duty to give notification of any defects or irregularities in
any notice of withdrawal  or will incur  any liability for  failure to give  any
such notification.

    4.   ACCEPTANCE FOR PAYMENT AND PAYMENT.   Upon the terms and subject to the
conditions of the  Offer (including, if  the Offer is  extended or amended,  the
terms  and  conditions  of  any  extension  or  amendment),  the  Purchaser will
purchase, by  accepting  for payment,  and  will  pay for,  all  Shares  validly
tendered  prior to the Expiration Date (and not properly withdrawn in accordance
with Section  3 above)  promptly after  the Expiration  Date. Any  determination
concerning  the satisfaction  of such terms  and conditions shall  be within the
sole discretion of  the Purchaser,  and such  determination shall  be final  and
binding  on all  tendering shareholders.  See Sections  1 and  14. The Purchaser
expressly reserves the right,  in its sole discretion,  to delay acceptance  for
payment  of, or payment for, Shares in order  to comply in whole or in part with
any applicable law, including, without limitation, the HSR Act. Any such  delays
will  be  effected  in compliance  with  Rule  14e-1(c) under  the  Exchange Act
(relating to the  Purchaser's obligation to  pay for or  return tendered  Shares
promptly after the termination or withdrawal of the Offer).

    Parent currently expects to file a Notification and Report Form with respect
to  the Offer under the HSR  Act during the week of  March 14, 1994. The waiting
period under the HSR Act  with respect to the Offer  will expire at 11:59  p.m.,
New  York  City time,  15  days after  such filing  is  made. The  Federal Trade
Commission (the "FTC") or  the Antitrust Division of  the Department of  Justice
(the   "Antitrust  Division")  may  extend  the  waiting  period  by  requesting
additional information or documentary material from Parent. If such a request is
made, such waiting period will expire at 11:59 p.m., New York City time, on  the
10th  day after substantial compliance by  Parent with such request. See Section
15  hereof  for  additional   information  concerning  the   HSR  Act  and   the
applicability of the antitrust laws to the Offer.

    In  all cases, payment for Shares accepted for payment pursuant to the Offer
will be made  only after timely  receipt by the  Depositary of certificates  for
such Shares (or a timely Book-Entry Confirmation with respect to such Shares), a
properly  completed  and  duly  executed  Letter  of  Transmittal  (or facsimile
thereof) and any other documents required by the Letter of Transmittal.

    For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased,  Shares properly tendered  to the Purchaser  and
not  withdrawn as, if and when the Purchaser gives oral or written notice to the
Depositary of the Purchaser's acceptance for payment of such Shares. Payment for
Shares accepted for payment pursuant to the Offer will be made by deposit of the
purchase price  therefor  with the  Depositary,  which  will act  as  agent  for
tendering  shareholders for the purpose of  receiving payment from the Purchaser
and transmitting the same to tendering shareholders. UNDER NO CIRCUMSTANCES WILL
INTEREST BE PAID ON THE PURCHASE  PRICE FOR SHARES, REGARDLESS OF ANY  EXTENSION
OF THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.

    If,  for any reason  whatsoever, acceptance for payment  of, or payment for,
Shares tendered pursuant to the Offer is  delayed or the Purchaser is unable  to
accept  for payment or pay  for tendered Shares, then,  without prejudice to the
Purchaser's rights under this Offer to Purchase (but subject to compliance  with
Rule  14e-1(c) under the Exchange Act, which  requires that a tender offeror pay
the consideration offered or return  the tendered securities promptly after  the
termination or withdrawal

                                       9
<PAGE>
of  a  tender  offer),  the  Depositary  may,  nevertheless,  on  behalf  of the
Purchaser, retain tendered Shares, and such Shares may not be withdrawn,  except
to  the  extent  tendering  shareholders  are  entitled  to  exercise,  and duly
exercise, withdrawal rights as described in Section 3.

    If any  tendered Shares  are not  purchased pursuant  to the  Offer for  any
reason,  or if certificates  submitted represent more  Shares than are tendered,
certificates for  Shares not  purchased or  tendered will  be returned,  without
expense  to the tendering  shareholder (or, in  the case of  Shares delivered by
book-entry transfer  into  the Depositary's  account  at a  Book-Entry  Transfer
Facility  pursuant to the procedures set forth in Section 2, such Shares will be
credited to  an  account  maintained  at  the  appropriate  Book-Entry  Transfer
Facility), as promptly as practicable after the expiration or termination of the
Offer.

    The  Purchaser reserves the  right to transfer  or assign, in  whole or from
time to time in part, to Parent or  one or more direct or indirect wholly  owned
subsidiaries  of Parent  the right to  purchase Shares tendered  pursuant to the
Offer, but any such transfer or assignment will not relieve the Purchaser of its
obligations under the Offer and will in no way prejudice the rights of tendering
shareholders to receive  payment for  Shares validly tendered  and accepted  for
payment pursuant to the Offer.

    5.   CERTAIN FEDERAL INCOME  TAX CONSEQUENCES.  Sales  of Shares pursuant to
the Offer (and the receipt of the right to receive cash pursuant to the  Merger)
will  be taxable transactions for Federal income tax purposes under the Internal
Revenue Code  of  1986,  as  amended  (the "Code"),  and  may  also  be  taxable
transactions  under applicable  state, local,  foreign and  other tax  laws. For
Federal income tax  purposes, a tendering  shareholder will generally  recognize
gain  or loss equal to the difference between the amount of cash received by the
shareholder pursuant to the Offer (or to be received pursuant to the Merger) and
the aggregate tax basis in the Shares tendered by the shareholder and  purchased
pursuant  to the Offer (or cancelled pursuant  to the Merger). Gain or loss will
be calculated  separately  for  each  block of  Shares  tendered  and  purchased
pursuant to the Offer.

    If  tendered Shares are  held by a tendering  shareholder as capital assets,
gain or loss  recognized by the  tendering shareholder will  be capital gain  or
loss,   which  will  be  long-term  capital   gain  or  loss  if  the  tendering
shareholder's holding period for the Shares exceeds one year.

    A shareholder  (other  than  certain exempt  shareholders  including,  among
others,  all corporations and  certain foreign individuals)  that tenders Shares
may be subject  to 31% backup  withholding unless the  shareholder provides  its
taxpayer identification number ("TIN") and certifies that such number is correct
or  properly certifies that  it is awaiting  a TIN. A  shareholder that does not
furnish its TIN  may be subject  to a  penalty imposed by  the Internal  Revenue
Service.  Each  shareholder should  complete and  sign  the Substitute  Form W-9
included with the  Letter of Transmittal  so as to  provide the information  and
certification necessary to avoid backup withholding.

    If  backup withholding applies to a  shareholder, the Depositary is required
to withhold 31% from payments to such shareholder. Backup withholding is not  an
additional  tax. Rather,  the amount of  the backup withholding  can be credited
against the Federal  income tax liability  of the person  subject to the  backup
withholding.  If backup withholding  results in an overpayment  of tax, a refund
can be obtained by the shareholder upon filing an income tax return.

    THE FOREGOING  DISCUSSION  MAY NOT  BE  APPLICABLE WITH  RESPECT  TO  SHARES
RECEIVED  PURSUANT TO  THE EXERCISE OF  OPTIONS OR OTHERWISE  AS COMPENSATION OR
WITH RESPECT TO HOLDERS OF SHARES WHO ARE SUBJECT TO SPECIAL TAX TREATMENT UNDER
THE  CODE,  SUCH  AS  FOREIGN  PERSONS,  LIFE  INSURANCE  COMPANIES,  TAX-EXEMPT
ORGANIZATIONS  AND  FINANCIAL INSTITUTIONS,  AND MAY  NOT APPLY  TO A  HOLDER OF
SHARES IN LIGHT OF SUCH HOLDER'S INDIVIDUAL CIRCUMSTANCES.

    THE FEDERAL INCOME TAX  DISCUSSION SET FORTH ABOVE  IS INCLUDED FOR  GENERAL
INFORMATION  ONLY, IS BASED ON THE LAW AS  CURRENTLY IN EFFECT AND IS SUBJECT TO
CHANGE, WHICH MAY BE RETROACTIVELY APPLIED. BECAUSE OF THE INDIVIDUAL NATURE  OF
TAX  CONSEQUENCES, EACH  SHAREHOLDER IS  URGED TO  CONSULT HIS  TAX ADVISOR WITH
RESPECT TO THE TAX CONSEQUENCES  TO HIM OF THE  OFFER AND THE MERGER,  INCLUDING
THE  EFFECTS OF FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND OF CHANGES
IN SUCH TAX LAWS.

    6.  PRICE RANGE OF THE SHARES; DIVIDENDS.  The Company has not paid any cash
dividends on the Shares since its initial public offering on December 21,  1989.
The  Shares are traded in  the over-the-counter market and  prices are quoted on
The Nasdaq  National Market  under the  symbol HNSI.  The following  table  sets
forth,  for the periods indicated,  the high and low  last reported sales prices
per Share as  reported by  The Nasdaq  National Market  and the  Dow Jones  News
Retrieval Service:

</TABLE>

    On  January 4, 1994, the  last trading day before  the initial filing of the
Registration Statement on Form  S-4 by Healthdyne with  respect to the  Exchange
Offer,  the reported closing  sales price of  the Shares on  The Nasdaq National
Market was $4.38 per share.

    On March  3, 1994,  the last  full  trading day  prior to  the date  of  the
announcement  by the Company that it had  entered into the Merger Agreement, the
reported closing sales  price of the  Shares on The  Nasdaq National Market  was
$6.75  per Share.  On March  9, 1994,  the last  full trading  day prior  to the
commencement of the Offer, the reported closing sales price of the Shares on The
Nasdaq National Market  was $7.75 per  Share. Shareholders are  urged to  obtain
current market quotations for the Shares.

    7.   EFFECT OF THE OFFER AND THE  MERGER ON THE MARKET FOR THE SHARES, STOCK
QUOTATION, EXCHANGE ACT REGISTRATION  AND MARGIN REGULATIONS.   The purchase  of
Shares  pursuant  to the  Offer  will reduce  the  number of  Shares  that might
otherwise trade publicly and the number of holders of Shares and could adversely
affect the liquidity and market value of the remaining Shares.

    Depending upon the  number of Shares  purchased pursuant to  the Offer,  the
Shares  may no longer meet the requirements  of the NASD for continued inclusion
in The Nasdaq National Market (the top tier market of The Nasdaq Stock  Market),
which require that an issuer have at least 200,000 publicly held shares, held by
at  least 400 shareholders or 300 holders of  round lots, with a market value of
$1 million, and have  net tangible assets  of at least either  $2 million or  $4
million,  depending on profitability levels during the issuer's four most recent
fiscal years. If  these standards  are not  met, the  Shares might  nevertheless
continue  to be included in The Nasdaq Stock Market with quotations published in
the Nasdaq "additional list" or in one  of the "local lists", but if the  number
of  holders of the Shares were  to fall below 300, or  if the number of publicly
held Shares were to fall below 100,000 or there were not at least two registered
and active  market makers  for the  Shares, the  NASD's rules  provide that  the
Shares  would no  longer be  "qualified" for  Nasdaq reporting  and Nasdaq would
cease to provide any quotations. Shares held directly or indirectly by officers,
directors or beneficial owners of more than 10% of the Shares are not considered
as being publicly held  for this purpose.  As of February  28, 1994, there  were
approximately  282 holders  of record of  Shares. The Company  has satisfied the
NASD's requirement for at  least 400 shareholders in  the past by  demonstrating
that  it has more than 400 beneficial owners of Shares. The Company estimates it
has in excess of 2,000 beneficial shareholders. If, as a result of the  purchase
of  Shares pursuant to the Offer, the  Shares no longer meet the requirements of
the NASD  for continued  inclusion in  The  Nasdaq Stock  Market or  the  Nasdaq
National Market and the Shares are no longer included in The Nasdaq Stock Market
or the

                                       11
<PAGE>
Nasdaq  National Market  (as the case  may be),  the market for  Shares could be
adversely affected. In the event that the Shares no longer meet the requirements
of the NASD for quotation through Nasdaq  and the Shares are no longer  included
in  The Nasdaq Stock  Market, it is  possible that the  Shares would continue to
trade in the over-the-counter market and that price quotations would be reported
by other  sources. The  extent  of the  public market  for  the Shares  and  the
availability  of  quotations reported  by other  sources  would depend  upon the
number of holders of Shares remaining at such time, the interest in  maintaining
a  market in Shares on the part of securities firms, the possible termination of
registration of the Shares under the Exchange Act, as described below, and other
factors.

    The Shares are currently registered under the Exchange Act. Registration  of
the  Shares under  the Exchange  Act may be  terminated upon  application of the
Company to the Commission if the Shares are not listed on a national  securities
exchange  and there are fewer than 300 record holders of the Shares. Termination
of registration of the Shares under the Exchange Act would substantially  reduce
the  information required to be furnished by the Company to its shareholders and
to the Commission and would make inapplicable to the Company certain  provisions
of  the  Exchange Act,  such as  the short-swing  profit recovery  provisions of
Section 16(b), the requirement  to furnish proxy  statements in connection  with
shareholders'  meetings pursuant to  Section 14(a) and  the requirements of Rule
13e-3 under  the Exchange  Act  with respect  to "going  private"  transactions.
Furthermore,  if  the Purchaser  acquires a  substantial  number of  Shares, the
ability  of  "affiliates"  of  the  Company  and  persons  holding   "restricted
securities" of the Company to dispose of such securities pursuant to Rule 144 or
144A  promulgated under the Securities Act of 1933 (the "Securities Act") may be
impaired or eliminated. It is the present intention of the Purchaser to seek  to
cause  the Company to make an application for termination of registration of the
Shares under the Exchange  Act as soon  as possible following  the Offer if  the
requirements for termination of registration are met.

    The  Shares are currently  "margin securities" under  the regulations of the
Board of Governors of the Federal Reserve System (the "Federal Reserve  Board"),
which  has the effect, among other things,  of allowing brokers to extend credit
on the  collateral  of the  Shares.  Depending  upon factors  similar  to  those
described  above regarding listing  and market quotations,  it is possible that,
following the Offer, the Shares  would no longer constitute "margin  securities"
for  the purposes  of the  margin regulations of  the Federal  Reserve Board and
therefore could no longer be  used as collateral for  loans made by brokers.  If
registration  of Shares under the Exchange Act were terminated, the Shares would
no longer be "margin securities" or be eligible for Nasdaq reporting.

    In any event,  the Shares  will cease  to be  reported on  The Nasdaq  Stock
Market,  and will no longer be registered  under the Exchange Act, following the
consummation of the Merger.

    8.  CERTAIN INFORMATION CONCERNING THE COMPANY.  The Company is a New Jersey
corporation with its principal executive offices at 1850 Parkway Place, Eleventh

    Prior  to the execution of the Merger Agreement, the Company provided Parent
with preliminary copies  of the  Company's unaudited  1993 financial  statements
(the  "Unaudited  1993 Financial  Statements"),  which included  the information
released publicly by the Company on March 8, 1994.

    BUDGET FOR 1994.   During the course of  discussions between Parent and  the
Company  that led to the execution of  the Merger Agreement (see Sections 11 and
12), the  Company  provided  Parent  with certain  annual  and  monthly  budgets
prepared  for  planning  purposes and  not  for purposes  of  forecasting future
operating performance. The Company disclosed to Parent, among other things, that
the Company's budgeted revenues,  operating income and net  income for the  year
ending  December 31,  1994 were $136.9  million, $6.7 million  and $2.4 million,
respectively.  In  addition,  the  Company   disclosed  to  Parent  a   budgeted
shareholders' equity of $61.6 million at December 31, 1994.

                                       13
<PAGE>
    The Company does not as a matter of course make public any projections as to
future  performance or  earnings. The  foregoing budgets  were not  prepared for
publication or with  a view to  complying with the  published guidelines of  the
Commission  regarding projections  or with  the American  Institute of Certified
Public Accountants Guide for Prospective Financial Statements, and are  included
in  this Offer to Purchase only because  such information was provided to Parent
by  the  Company.  While  presented  with  numerical  specificity,  the  budgets
described  above  necessarily  reflect  numerous  assumptions  with  respect  to
industry performance, general business and economic conditions, the availability
and cost of capital and other  matters, many of which are inherently  uncertain,
difficult or impossible to predict or beyond the Company's control. Accordingly,
one  cannot predict whether the assumptions  made in preparing such budgets will
prove accurate.  Such budgets  are inherently  imprecise, and  there can  be  no
assurance  that they can  be realized. Also,  it is expected  that there will be
differences between actual  and budgeted  results, and actual  results may  vary
materially  from  those  contained  in  such  budgets.  The  inclusion  of  this
information should not be regarded as an indication that Parent, the  Purchaser,
the  Company,  Dillon,  Read,  or  anyone  else  who  received  this information
considered it to predict future events reliably, and this information should not
be relied on as such. None of  Parent, the Purchaser, the Company, Dillon,  Read
or   any  other  person   to  whom  such  budgets   were  provided  assumes  any
responsibility for  the validity,  reasonableness, accuracy  or completeness  of
such  budgets,  and the  Company has  made  no representation  to Parent  or the
Purchaser regarding such budgets.

    ADDITIONAL INFORMATION.  The Company is subject to the informational  filing
requirements  of the Exchange Act and,  in accordance therewith, is obligated to
file reports and other information with the Commission relating to its business,
financial condition  and other  matters. Information,  as of  particular  dates,
concerning  the Company's  directors and  officers, their  remuneration, Options
granted to  them, the  principal holders  of the  Company's securities  and  any
material  interest of such persons in  transactions with the Company is required
to be disclosed in  proxy statements distributed  to the Company's  Shareholders
and  filed  with  the  Commission.  Such  reports,  proxy  statements  and other
information  should  be  available  for  inspection  at  the  public   reference
facilities  of the Commission at 450 Fifth Street, N.W., Washington, D.C. 20549,

Commission's principal office at 450 Fifth Street, N.W., Washington, D.C. 20549.

concerning  the Company  contained herein  has been  taken from,  or based upon,
publicly available  documents on  file with  the Commission  and other  publicly

</TABLE>

    For the year ended December 31, 1993, Parent reported consolidated sales and
revenues of  $4,408.4  million;  income from  continuing  operations  of  $134.4
million;  net  income  of  $26.0  million;  earnings  per  share  for continuing
operations of $1.46 ($1.45 on a fully diluted basis); and earnings per share  of
$.28 ($.28 on a fully diluted basis).

    Except as set forth in Schedule I to this Offer to Purchase, none of Parent,
the  Purchaser or, to  the best knowledge  of the Purchaser,  any of the persons
listed therein or any associate or subsidiary of Parent, the Purchaser or any of
the persons so listed, beneficially owns  any equity securities of the  Company,
and  except as  set forth  in Schedule  II to  this Offer  to Purchase,  none of
Parent, the Purchaser or,  to the best  knowledge of the  Purchaser, any of  the
other  persons referred to above, or  any of the respective directors, executive
officers or subsidiaries of any of the foregoing, has effected any  transactions
in any equity securities of the Company during the past 60 days.

    Except  as described in this Offer to  Purchase, (a) there have not been any
contacts, transactions or  negotiations between  Parent, the  Purchaser, any  of
their  respective  subsidiaries, or,  to the  best knowledge  of Parent  and the
Purchaser, any of the persons listed in Schedule I hereto, on the one hand,  and
the  Company or any of its directors, officers or affiliates, on the other hand,
that are required to be disclosed pursuant  to the rules and regulations of  the
Commission  and (b) none of  Parent, the Purchaser or,  to the best knowledge of
Parent and the Purchaser, any of the persons listed in Schedule I hereto has any
contract, arrangement,  understanding  or  relationship  with  any  person  with
respect to any securities of the Company.

    10.   SOURCE AND AMOUNT OF FUNDS.  If all Fully Diluted Shares are purchased
pursuant to the  Offer, the amount  required by the  Purchaser to purchase  such
Shares and to pay related fees and

                                       16
<PAGE>
expenses  will be approximately $116 million.  The Purchaser plans to obtain all
such funds through capital contributions or advances made by Parent or its other
subsidiaries. Parent plans to obtain the funds for such capital contributions or
advances from its  available cash  and working  capital. The  Purchaser has  not
conditioned the Offer on obtaining financing.

    11.   CONTACTS WITH  THE COMPANY; BACKGROUND  OF THE OFFER.   On February 4,
1994, Dillon, Read  contacted Peter  Spears, President of  Parent's home  health
care  subsidiary, to ascertain  whether Parent would  be interested in acquiring
the Company.  On  February  9, 1994,  Parent  and  Dillon, Read,  as  agent  for
Healthdyne,  entered into a confidentiality  agreement pursuant to which Parent,
among other things, agreed  to keep certain  information concerning the  Company
confidential  and to use such information solely for the purpose of evaluating a
possible transaction between  Parent and  the Company.  On February  10 and  11,
1994,  Parent received a  management presentation from  Healthdyne and the chief
executive and chief financial officers of the Company and was given access to  a
data  room to conduct preliminary due diligence. Based on such due diligence, on
February 16, 1994, Grace submitted to  Dillon, Read a non-binding indication  of
interest to acquire the Company. On February 17, 1994, the Board of Directors of
Healthdyne  authorized its management to  proceed with further negotiations with
Parent and authorized Healthdyne to agree with Parent that Healthdyne would  not
solicit  or negotiate any  other proposal or  enter into any  agreement with any
other person providing for the sale of the Company or the sale of the Healthdyne
Shares through March 11, 1994. On February  24, 1994, the Board of Directors  of
the  Company  authorized  the  Company  to proceed  with  the  negotiation  of a
transaction providing for the  sale of the Company  to Parent. The Company  also
agreed  with Parent that  the Company would  not solicit or  negotiate any other
proposal or enter  into any agreement  with any other  person providing for  the
sale of the Company through March 11, 1994.

    During the weeks of February 21 and 28, 1994, while Parent continued its due
diligence  investigation  of the  Company,  Parent, Healthdyne  and  the Company
negotiated the final  purchase price  and structure of  the transaction.  During
these  negotiations, Healthdyne advised Parent that  it had filed a registration
statement with the Commission  on January 5, 1994  with respect to the  Exchange
Offer,  in  which Healthdyne  would  acquire approximately  2.15  million Shares
(approximately 18% of the  Company's outstanding Shares) by  exchanging .8 of  a
share  of  Healthdyne common  stock for  each Share  tendered and  accepted. The
Boards of  Directors  of  each  of  Parent  and  the  Purchaser  authorized  the
transactions  contemplated  by  the  Merger  Agreement  and  the  Stock Purchase
Agreement on March 3, 1994, subject to satisfactory resolution of the  remaining
contractual issues. On March 4, 1994, the parties reached final agreement on all
terms  and conditions of the Merger  Agreement and the Stock Purchase Agreement,
the Boards  of Directors  of  the Company  and  Healthdyne approved  the  Merger
Agreement  and  the  Stock  Purchase Agreement,  respectively,  and  the parties
entered into such Agreements and announced that they had done so. In view of the
execution of the Merger Agreement  and the Stock Purchase Agreement,  Healthdyne
also announced on March 4, 1994 that it would not pursue the Exchange Offer.

    12.    PURPOSE  OF  THE  OFFER; THE  MERGER  AGREEMENT;  THE  STOCK PURCHASE
AGREEMENT.

    The purpose of the Offer and the Merger is to acquire control of the Company
and the entire equity interest in  the Company. The Purchaser intends,  pursuant
to the terms and conditions of the Merger Agreement, to consummate the Merger.

    Parent  and  Purchaser  reserve  the  right  to  acquire  additional  Shares
following  the  expiration  of  the  Offer  through  private  purchases,  market
transactions, tender or exchange offers or otherwise on terms and at prices that
may  be  more or  less favorable  than those  of  the Offer  or, subject  to any
applicable legal  requirements, to  dispose of  any or  all Shares  acquired  by
Parent and the Purchaser.

THE MERGER AGREEMENT

    THE  MERGER.   The Merger  Agreement provides  that, as  soon as practicable
following the satisfaction  or waiver  of all conditions  described below  under
"Conditions to the Merger", the Purchaser will

                                       17
<PAGE>
be merged with and into the Company, which shall be the surviving corporation in
the Merger (the "Surviving Corporation"), and each Share then outstanding (other
than  Shares owned by  Parent or the  Purchaser or any  other direct or indirect
subsidiary of Parent immediately prior to the Effective Time) will be  converted
into  the right  to receive  from the Surviving  Corporation $7.85  per share in
cash, without  interest, or  any higher  price per  Share paid  pursuant to  the
Offer.

    VOTE  REQUIRED TO APPROVE  MERGER.  The NJBCA  requires, among other things,
that any  plan of  merger or  consolidation  of the  Company must  generally  be
approved  by the  Board of Directors  of the Company  and by the  holders of the
Company's outstanding voting securities. The  Board of Directors of the  Company
has  approved the Offer and the Merger; consequently, the only additional action
that may be necessary to effect the Merger is approval by such shareholders,  if
the  "short-form" merger procedure  described below is  not available. Under the
NJBCA, the affirmative  vote of  the holders of  a majority  of the  outstanding
Shares  (including any Shares owned by  the Purchaser), is generally required to
approve the Merger.  If the  Purchaser acquires,  through the  Offer, the  Stock
Purchase  Agreement  or  otherwise, voting  power  with  respect to  at  least a
majority of  the outstanding  Shares, which  would be  the case  if the  Minimum
Condition  is  satisfied, it  will have  sufficient voting  power to  effect the
Merger without the vote of any  other shareholder of the Company. Healthdyne  is
the beneficial holder of 7,800,000 Shares, constituting approximately 66% of the
Fully  Diluted Shares and,  subject to certain conditions,  has agreed to tender
and sell such shares pursuant  to the Offer. The NJBCA  also provides that if  a
parent  company owns at  least 90% of each  class of stock  of a subsidiary, the
parent company can effect a "short-form" merger with that subsidiary without the
authorization of  the other  shareholders of  the subsidiary.  Accordingly,  if,
pursuant  to the Offer, the Stock  Purchase Agreement or otherwise the Purchaser
acquires or controls the voting power of at least 90% of the outstanding Shares,
the Purchaser could, and intends to,  effect the Merger without the approval  of
any other shareholder of the Company.

    The  Company has agreed  in the Merger  Agreement to cause  a meeting of its
shareholders to  be duly  called  and held  as  soon as  reasonably  practicable
following consummation of the Offer for the purpose of voting on the approval of
the  Merger  Agreement and  the  Merger, unless  the  Merger may  be consummated
unilaterally by the Purchaser pursuant to the "short-form" merger provisions  of
the NJBCA. The Merger Agreement also provides that the Board of Directors of the
Company  will (except to the  extent that, upon advice  of counsel, the Board of
Directors reasonably believes  is otherwise  required by  its fiduciary  duties)
recommend  approval  of the  Merger Agreement  and the  Merger by  the Company's
shareholders and  that the  Company will  use  its best  efforts to  obtain  the
necessary  approvals of  the Merger  Agreement and  the Merger  by the Company's
shareholders.  The  Purchaser  has  agreed   to  vote  all  outstanding   Shares
beneficially  owned by it in  favor of the approval  of the Merger Agreement and
the Merger.

    CONDITIONS TO THE MERGER.  The Merger Agreement provides that the respective
obligations of the Company,  Parent and the Purchaser  to effect the Merger  are
subject  to the satisfaction of the following conditions: (a) the waiting period
(or any extension thereof)  applicable to the consummation  of the Merger  under
the  HSR Act shall  have expired or  been terminated, (b)  if required under the
NJBCA, the  Merger Agreement  and the  Merger shall  have been  approved by  the
holders  of a  majority of  the Shares  (including Shares  beneficially owned by
Parent) and  (c)  no  temporary  restraining  order,  preliminary  or  permanent
injunction  or other order preventing the  consummation of the Merger shall have
been issued by any Federal or state court.

    The Merger Agreement further provides that (a) the obligation of the Company
to effect the Merger is subject to the condition that each of the Purchaser  and
Parent  shall  in  all  material respects  have  performed  each  obligation and
agreement and complied with each covenant  to be performed and complied with  by
it  under the  Merger Agreement at  or prior to  the Effective Time  and (b) the
obligations of Parent and the Purchaser to effect the Merger are subject to  the
satisfaction  at or prior to the Effective Time of the following conditions: (i)
the Company shall in  all material respects have  performed each obligation  and
agreement  and complied with each covenant to  be performed and complied with by
it under the Merger  Agreement, (ii) Parent (or  any of its subsidiaries)  shall
have

                                       18
<PAGE>
purchased  Shares pursuant to the Offer and the transactions contemplated by the
Stock Purchase Agreement shall have been consummated and (iii) all Options shall
have been surrendered or cancelled.

    TERMINATION OF  THE MERGER  AGREEMENT.   The Merger  Agreement provides  for
termination  at any time prior to the  Effective Time, whether prior to or after
approval by the shareholders of the Company: (a) by mutual consent of Parent and
the Company; (b) by either  Parent or the Company if  the Merger shall not  have
been  consummated by June 30, 1994; (c) by  Parent if (i) neither Parent nor any
subsidiary of Parent shall  have purchased any Shares  pursuant to the Offer  by
May 31, 1994 or (ii) Parent has properly terminated the Offer in accordance with
its  terms; (d) by  the Company if  neither Parent nor  any subsidiary of Parent
shall have commenced (within the meaning of the Exchange Act) the Offer by March
10, 1994; (e) by the Company if the Board of Directors of the Company shall have
properly exercised its rights with respect  to a superior takeover proposal,  as
described  under "Other Offers" below; (f) by  Parent, if the Board of Directors
of the Company shall have  (i) exercised its rights  with respect to a  superior
takeover  proposal as described under "Other Offers" below, or (ii) provided any
information to any party prior to the acceptance for payment of Shares  pursuant
to  the Offer, as described under  "Other Offers" below; PROVIDED, HOWEVER, that
Parent shall not terminate the Merger Agreement pursuant to clause (i) if, as  a
result  of the Company's receipt of a  takeover proposal from a third party, the
Company, as required  by applicable law,  takes and discloses  to the  Company's
shareholders  a  position contemplated  by Rule  14e-2(a)(2) or  (3) promulgated
under the  Exchange  Act with  respect  to  such proposal  or  the  transactions
contemplated  thereby  and  if  within  five  business  days  after  taking  and
disclosing to its shareholders the aforementioned position the Company  publicly
reconfirms  its recommendation  of the  transactions contemplated  by the Merger
Agreement; (g) by the Company, if there shall have been any material breach of a
material obligation of Parent  or the Purchaser under  the Merger Agreement  and
such  default shall  have not  been remedied within  five days  after receipt by
Parent or the  Purchaser, as  the case  may be, of  notice in  writing from  the
Company specifying such breach and requesting that it be remedied; (h) by Parent
and  the Purchaser if  there shall have  been any material  breach of a material
obligation of  the Company  thereunder  and such  default  shall not  have  been
remedied within five days after receipt by the Company of notice in writing from
Parent  or  the  Purchaser specifying  such  breach  and requesting  that  it be
remedied; or (i) by  Parent and the Purchaser,  if the Stock Purchase  Agreement
shall have been terminated.

    In  the event of  termination of the Merger  Agreement, the Merger Agreement
will become void  and there  will be  no liability on  the part  of Parent,  the
Purchaser or the Company, except that (a) the provisions of the Merger Agreement
with   respect  to  expenses  and  the  treatment  and  return  of  confidential
information shall survive any such termination,  and (b) no party to the  Merger
Agreement  will  be  relieved  of  liability  for  any  willful  breach  of  any
representation or  warranty or  any  breach prior  to  such termination  of  any
covenant or agreement contained therein.

    OTHER OFFERS.  The Merger Agreement provides that the Company shall not, nor
shall it permit any of its subsidiaries or affiliates to, nor shall it authorize
or  permit  any officer,  director  or employee  of,  or any  investment banker,
attorney or  other advisor  or representative  of,  the Company  or any  of  its
subsidiaries  to, (a) solicit or initiate, or knowingly encourage any submission
of, any takeover proposal (as defined below) (b) participate in any  discussions
or negotiations regarding, or furnish to any person any information with respect
to, any takeover proposal (except for (i) non-confidential information furnished
in  response  to inquiries  by  securities analysts  or  institutional investors
concerning the Offer or the Merger  or (ii) information the Company is  required
to  furnish pursuant to Section 14A:5-28  of the NJBCA); PROVIDED, HOWEVER, that
prior to the  acceptance for payment  of Shares  pursuant to the  Offer, to  the
extent  required by the fiduciary  obligations of the Board  of Directors of the
Company, as determined  in good faith  by the  Board of Directors  based on  the
written  advice  of outside  counsel,  the Company  may  (A) in  response  to an
unsolicited request therefor,  furnish information with  respect to the  Company
(pursuant  to a customary  confidentiality agreement at  least as restrictive as
the Company's Confidentiality Agreement  with the Parent  (as determined by  the

                                       19
<PAGE>
Company's  outside counsel)) to any person who has indicated to the Company that
it is interested in  pursuing a qualified takeover  proposal (as defined  below)
and  discuss  such  information (but  not  the  terms of  any  possible takeover
proposal) with such person and  (B) upon receipt by  the Company of a  qualified
takeover  proposal, following delivery to Parent  of notice stating the identity
of the person making such qualified takeover proposal and the material terms  of
such  qualified takeover  proposal, participate  in negotiations  regarding such
qualified takeover proposal.  Without limiting the  foregoing, any violation  of
the  restrictions set  forth in  the preceding  sentence by  any officer  of the
Company or any of its subsidiaries  or any investment banker, attorney or  other
advisor  or representative of the Company or any of its subsidiaries, whether or
not such person  is purporting to  act on behalf  of the Company  or any of  its
subsidiaries or otherwise, shall be deemed to be a breach by the Company of such
provision.  For purposes of the Merger  Agreement, "takeover proposal" means any
proposal for a merger or other business combination involving the Company or any
subsidiary or  any proposal  or offer  to  acquire in  any manner,  directly  or
indirectly,  a  substantial portion  of the  assets of  the Company,  any equity
interest in or  voting securities  of the Company  (other than  pursuant to  the
Stock  Option  Plans or  the  Stock Purchase  Plan),  and a  "qualified takeover
proposal" means a proposal to acquire all the Shares by merger, tender offer  or
otherwise  at a  purchase price  that includes  cash consideration  in excess of
$7.85 per share, which in the good faith determination of the Board of Directors
of the Company is reasonably likely to be fully financed.

    The Merger Agreement also  provides that neither the  Board of Directors  of
the  Company nor any committee thereof shall  (a) withdraw or modify, or propose
to withdraw or  modify, in  a manner  adverse to  Parent or  the Purchaser,  the
approval  or recommendation by the  Board of Directors or  any such committee of
the Offer, the  Merger Agreement  or the Merger,  (b) approve  or recommend,  or
propose  to approve or  recommend, any takeover  proposal or (c)  enter into any
agreement with respect to any takeover proposal. Notwithstanding the  foregoing,
in  the event the Board of Directors of the Company receives a superior takeover
proposal (as defined  below), the  Board of  Directors may  (subject to  certain
limitations  contained in the Merger Agreement)  withdraw or modify its approval
or recommendation of the Offer, the  Merger Agreement or the Merger, approve  or
recommend  any such  superior takeover  proposal, enter  into an  agreement with
respect  to  any  such  superior  takeover  proposal  or  terminate  the  Merger
Agreement,  in each case  at any time  after 48 hours  following the Purchaser's
receipt of written notice  (a "Notice of  Superior Takeover Proposal")  advising
Parent  that  the Board  of Directors  of  the Company  has received  a superior
takeover proposal, specifying the material terms and conditions of such superior
takeover proposal  and  identifying the  person  making such  superior  takeover
proposal.  The Company  may take  any of the  foregoing actions  pursuant to the
preceding sentence only  if the  Purchaser shall  not have  accepted Shares  for
payment  pursuant to the  Offer. In addition,  if the Company  proposes to enter
into an agreement with  respect to any takeover  proposal, terminate the  Merger
Agreement,  approve or  recommend a  superior takeover  proposal or  withdraw or
modify its approval or recommendation of the Offer, the Merger Agreement or  the
Merger,  it is required,  within two business  days following the  taking of any
such action,  to pay  or cause  to be  paid to  Parent the  Termination Fee  (as
defined  under  "Costs and  Expenses" below).  Nothing  contained in  the Merger
Agreement  shall  prohibit  the  Company  from  taking  and  disclosing  to  its
shareholders a position contemplated by Rule 14e-2(a) following Parent's receipt
of  a Notice of Superior  Takeover Proposal, provided that  the Company does not
withdraw or modify  its position  with respect  to the  Offer or  the Merger  or
approve  or recommend a takeover proposal. For purposes of the Merger Agreement,
a "superior takeover proposal" means a qualified takeover proposal having  terms
which  the  Board of  Directors  of the  Company  determines in  its  good faith
reasonable judgment  (based  on advice  of  a financial  advisor  of  nationally
recognized  reputation) to be more favorable  to the Company's shareholders than
the Offer and the Merger.

    The Company has agreed  to promptly advise Parent  orally and in writing  of
any  request for information  or of any  takeover proposal, or  any inquiry with
respect to any  takeover proposal,  the material  terms and  conditions of  such
request,  takeover proposal  or inquiry, and  the identity of  the person making
such takeover proposal or inquiry. The  Company has agreed to keep Parent  fully
informed  of the status  and details of  any such request,  takeover proposal or
inquiry.

                                       20
<PAGE>
    COSTS AND  EXPENSES.   The  Merger  Agreement  provides that  all  fees  and
expenses incurred in connection with the Offer, the Merger, the Merger Agreement
and  the transactions contemplated thereby shall  be paid by the party incurring
such fees or expenses, whether or not the Offer or the Merger is consummated.

    Notwithstanding the  foregoing, the  Company is  required to  pay to  Parent
within   two  business  days  of  demand  therefor  a  fee  of  $4,553,000  (the
"Termination Fee"),  payable  in same  day  funds,  if a  takeover  proposal  is
commenced,  publicly proposed, publicly disclosed or communicated to the Company
(or the  willingness of  any person  to  make a  takeover proposal  is  publicly
disclosed  or communicated  to the  Company) and the  Board of  Directors of the
Company, pursuant to the  terms of the Merger  Agreement, withdraws or  modifies
its approval or recommendation of the Merger Agreement, the Offer or the Merger,
approves  or recommends such  other takeover proposal,  enters into an agreement
with respect to such other takeover proposal or terminates the Merger Agreement.
The Company is required to pay to  Parent within two business days after  demand
therefor  all  Expenses (up  to  but not  in excess  of  $500,000), but  not the
Termination Fee, if Parent  terminates the Merger  Agreement pursuant to  clause
(f)(ii)  set  forth  herein under  "Termination  of the  Merger  Agreement". For
purposes of this  paragraph, "Expenses"  shall mean all  out-of-pocket fees  and
expenses  incurred or paid by or on behalf  of the Parent in connection with the
Offer, the Merger or the consummation of any of the transactions contemplated by
the Merger Agreement,  including all  fees and expenses  of counsel,  investment
banking firms, accountants, experts and consultants to Parent.

    CONDUCT  OF THE  COMPANY'S BUSINESS  UNTIL THE  EFFECTIVE TIME.   The Merger
Agreement provides  that  from  the  date of  the  Merger  Agreement  until  the
Effective  Time, except as consented  to by Parent, or  as expressly provided in
the Merger Agreement, the businesses of  the Company and its subsidiaries  shall
be  conducted only in, and  the Company and its  subsidiaries shall not take any
action except  in, the  ordinary course  of business  and consistent  with  past
practice. In addition, the Company has agreed to use reasonable business efforts
to   preserve  intact  the   business  organization  of   the  Company  and  its
subsidiaries, to keep available the services  of its and their present  officers
and  key  employees, and  to preserve  the  good will  of those  having business
relationships with it and their respective subsidiaries.

    The Merger  Agreement further  provides that  from the  date of  the  Merger
Agreement  until the  Effective Time,  except as consented  to by  Parent, or as
expressly provided in the Merger Agreement, (a) the Company shall not, (i)  sell
or  pledge or  agree to  sell or  pledge any  stock owned  by it  in any  of its
subsidiaries; (ii) amend its Certificate  of Incorporation or By-Laws; or  (iii)
split,  combine  or  reclassify any  shares  of its  outstanding  capital stock,
declare, set aside or  pay any dividend or  other distribution payable in  cash,
stock  or property,  or redeem  or otherwise acquire  any shares  of its capital
stock or shares of the capital stock of any of its subsidiaries; (b) the Company
shall not, and shall cause  each of its subsidiaries  not to, (i) authorize  for
issuance,  issue or  sell any  additional shares  of, or  rights of  any kind to
acquire any  shares of,  its capital  stock of  any class  (whether through  the
issuance or granting of options, warrants, commitments, subscriptions, rights to
purchase  or otherwise), except  for unissued Shares  reserved for issuance upon
the exercise of Options in accordance with their existing terms, as such Options
may be accelerated pursuant to their existing terms, and except with respect  to
the  Stock Purchase  Plan; (ii) acquire,  dispose of,  transfer, lease, license,
mortgage, pledge or encumber any fixed or other substantial assets other than in
the ordinary course of business and consistent with past practice; (iii)  incur,
assume  or prepay  any material indebtedness  or any  other material liabilities
other than  in the  ordinary course  of business  under the  Company's  existing
credit  agreement and consistent with past practice, (iv) assume, endorse (other
than in  the  ordinary  course  of  business  consistent  with  past  practice),
guarantee   or  otherwise  become  liable   or  responsible  (whether  directly,
contingently or  otherwise) for  the material  obligations of  any other  person
(other  than a  subsidiary); (v)  make any  material loans,  advances or capital
contributions to, or investments in, any

                                       21
<PAGE>
other  person, other  than a  subsidiary, or  otherwise enter  into any material
contract other than in the ordinary course of business and consistent with  past
practice;  (vi) make any loans  to employees, other than  travel advances in the
ordinary  course  of  business;  (vii)  fail  to  maintain  adequate   insurance
consistent  with past practice for their businesses and properties; (viii) other
than commitments previously disclosed  in writing by the  Company to Parent  and
other  than the  acquisition of  equipment in  the ordinary  course of business,
undertake, make or commit  to undertake or make  any capital expenditures in  an
amount  greater than $10,000 per individual capital expenditure and no more than
$100,000 per month in  the aggregate (on  a combined basis  for the Company  and
subsidiaries);  or  (ix)  enter  into  any  contract,  agreement,  commitment or
arrangement with respect to any of the foregoing; (c) the Company shall not, and
shall cause its subsidiaries  not to, (i) enter  into any new agreements  (other
than,  in  its  ordinary  course  of  business  consistent  with  past practice,
agreements substantially in the form  of the Company's standard form  Management
Agreement  having a provision requiring not more than thirty (30) days notice to
terminate any such agreement (the "Management Agreements")), or amend or  modify
any existing agreements (other than Management Agreements in its ordinary course
of  business  consistent  with  past  practice)  with  any  of  their respective
officers, directors  or employees  or with  any "disqualified  individuals"  (as
defined  in  Section 280G(c)  of  the Code),  (ii)  grant any  increases  in the
compensation of  their  respective  directors, officers  and  employees  or  any
"disqualified  individuals",  other than  increases  in the  ordinary  course of
business and consistent with past practice  to persons who are not directors  or
corporate  officers of or "disqualified individuals" with respect to the Company
or any subsidiary, (iii) enter into, adopt, amend or terminate, or grant any new
benefit  not  presently  provided  for  under,  any  employee  benefit  plan  or
arrangement,  except as required by law  or to maintain the tax-qualified status
of the plan;  PROVIDED, HOWEVER, that  the Company is  permitted to pay  bonuses
pursuant  to its 1993 corporate bonus plan  and additional bonuses not to exceed
in the aggregate  amounts accrued  with respect  thereto in  the Unaudited  1993
Financial  Statements; or (iv) take any action  with respect to the grant of any
severance or termination pay other than  in the ordinary course of business  and
consistent  with past practice and pursuant to policies in effect on the date of
the Merger  Agreement; (d)  the Company  shall  not, and  shall not  permit  any
subsidiary  to, acquire or agree to acquire by merging or consolidating with, or
by purchasing a substantial portion  of the assets of,  or by any other  manner,
any  business  or any  corporation, partnership,  association or  other business
organization or division thereof  or otherwise acquire or  agree to acquire  any
assets  (other than equipment, inventory and  supplies in the ordinary course of
business) that are material,  individually or in the  aggregate, to the  Company
and  its subsidiaries  taken as a  whole and (e)  the Company will  not call any
meeting of its  shareholders to be  held prior to  June 30, 1994  other than  as
required by law or the Merger Agreement.

    BOARD  OF DIRECTORS.  The Merger Agreement provides that, subject to Section
14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, effective  upon
the  acceptance for  payment of,  and payment for,  any Shares  by the Purchaser
pursuant to the Offer or the Stock Purchase Agreement that represent at least  a
majority  of  the  Fully Diluted  Shares,  the  Purchaser shall  be  entitled to
designate the directors serving  on the Board of  Directors of the Company,  and
the  Company shall,  at such time,  promptly increase  the size of  the Board of
Directors of  the Company  to the  extent necessary  to enable  the  Purchaser's
designees  to  be elected  to, and  to constitute  a majority  of, the  Board of
Directors of the  Company and  shall cause the  Purchaser's designees  to be  so
elected.  The Company has agreed to cooperate with Parent and the Purchaser with
respect  to  such  election  of  directors,  including  without  limitation  (a)
cooperating  in satisfying the requirements of Section 14(f) of the Exchange Act
and Rule 14f-1 promulgated thereunder, and (b) amending, prior to the Expiration
Date, any provisions of  its By-Laws or  any agreement by  which the Company  is
bound that could delay

                                       22
<PAGE>
or  hinder the ability of the Purchaser to  elect its designees to a majority of
the directorships constituting the  Board of Directors.  The Company has  agreed
not to take any action to delay or hinder such election.

    Certain  information required to be delivered  by Rule 14f-1 of the Exchange
Act in connection with Parent's designation of members of the Board of Directors
is included  as an  Annex to  the Company's  Schedule 14D-9  and in  Schedule  I
hereto.

    BENEFIT  PLANS AND CERTAIN  CONTRACTS.  The  Merger Agreement provides that,
for at least two  years following the consummation  of the Merger, employees  of
the  Company will be provided  with employee benefits that  in the aggregate are
not less  favorable  than those  provided  by  National Medical  Care,  Inc.  (a
subsidiary of Parent) to its employees who are similarly situated. Parent is not
obligated  under the Merger Agreement to continue the employment of any employee
of the Company or to continue the Stock Option Plans or the Stock Purchase  Plan
maintained  by  the Company.  All employees  of the  Company who  continue their
employment with the Company or any  subsidiary of Parent after the closing  date
under  the Stock  Purchase Agreement  or the  purchase of  the Healthdyne Shares
under the Offer (the "Cut-Off Date") will be given credit for their service with
the Company prior to  the Cut-Off Date for  purposes of determining  eligibility
and vesting (other than with respect to National Medical Care, Inc.'s retirement
plan)  under benefit plans sponsored by the Company, Parent or any subsidiary of
Parent applicable to such employees after the Cut-Off Date.

    INDEMNIFICATION.  Pursuant  to the  Merger Agreement, Parent  has agreed  to
cause  the Surviving  Corporation to  (a) either  (i) purchase  and maintain for
three years after the  Effective Time a directors'  and officers' insurance  and
indemnification policy, substantially equivalent to the Company's policy for all
officers  and  directors of  the Company  in effect  on the  date of  the Merger
Agreement, to cover acts and omissions of directors and officers of the  Company
occurring  prior to the Effective Time or (ii) request Healthdyne to obtain such
coverage and provide reimbursement to Healthdyne  for the cost thereof; and  (b)
maintain  in effect the current provisions of  the By-Laws of the Company (which
shall  be  contained  in  the  By-Laws  of  the  Purchaser  and  the   Surviving
Corporation) relating to the rights to indemnification of officers and directors
with  respect to indemnification  for acts and omissions  occurring prior to the
Effective Time.

    REPRESENTATIONS AND  WARRANTIES.    The Merger  Agreement  contains  various
customary  representations and warranties of the Company (which will not survive
consummation  of  the  Merger)  relating   to,  among  other  things,  (a)   the
organization  of the Company and its subsidiaries and similar corporate matters,
(b) the  capital  structure  of  the  Company  and  its  subsidiaries,  (c)  the
authorization,  execution and delivery of the Merger Agreement, the consummation
of the transactions contemplated  thereby and related  matters, (d) consent  and
approvals,  including  matters relating  to state  takeover laws,  (e) documents
filed by  the  Company with  the  Commission  and the  accuracy  of  information
contained  therein, (f) the accuracy of  information supplied by the Company for
use in documents filed with the Commission in connection with the Offer and  the
Merger,  (g) the absence of certain material changes or events, (h) broker's and
finder's fees, (i) litigation, (j) employee benefits plans and matters  relating
to  ERISA,  (k)  tax,  licensing  and  insurance  matters,  (l)  contracts,  (m)
compliance with applicable laws, (n)  earnout payments, (o) title to  properties
and (p) labor matters.

    ADDITIONAL  AGREEMENTS.  The Merger Agreement  provides that, subject to the
terms and conditions thereof, each of Parent, the Purchaser and the Company will
use all reasonable efforts to take, or cause to be taken, all actions and to do,
or cause to be done, all things necessary, proper or advisable to consummate and
make effective  the  transactions  contemplated  by the  Offer  and  the  Merger
Agreement, including filing a Certificate of Merger, using reasonable efforts to
remove  any  legal  impediment  to the  consummation  or  effectiveness  of such
transactions and using all reasonable  efforts to obtain all necessary  waivers,
consents  and approvals, and to effect  all necessary registrations and filings.
Each of the Company, Parent and the Purchaser has agreed in the Merger Agreement
to make  as  promptly as  practicable  all filings  and  submissions as  may  be
reasonably  required  under the  HSR Act.  Subject  to the  terms of  the Merger
Agreement, the Company has  agreed to furnish to  Parent and the Purchaser,  and
Parent  and  the Purchaser  will furnish  to the  Company, such  information and
assistance as the

                                       23
<PAGE>
other may reasonably  request in  connection with  the preparation  of any  such
filings or submissions. Subject to the terms of the Merger Agreement, and to the
preservation of attorney-client privilege and work-product doctrine, the Company
will provide Parent and the Purchaser, and Parent and the Purchaser will provide
the  Company, with copies  of all correspondence,  filings or communications (or
memoranda setting forth the substance thereof) between such party or any of  its
representatives,  on the one  hand, and any governmental  agency or authority or
members of  their respective  staffs, on  the other  hand, with  respect to  the
Merger  Agreement and the transactions  contemplated thereby; PROVIDED, HOWEVER,
that Parent  and the  Purchaser are  not required  to provide  the Company  with
copies of confidential documents or information included in Parent's filings and
submissions under the HSR Act.

    AMENDMENTS;  WAIVERS.   The  Merger Agreement  provides that  it may  not be
amended except by  an instrument  in writing  signed on  behalf of  each of  the
parties.

    Pursuant  to the Merger Agreement,  at any time prior  to the Effective Time
the parties  may  (a)  extend  the  time for  the  performance  of  any  of  the
obligations or other acts of the parties or (b) waive compliance with any of the
agreements or conditions contained in the Merger Agreement. Any agreement on the
part of a party to any such extension or waiver shall be valid only if set forth
in an instrument in writing signed on behalf of such party.

STOCK PURCHASE AGREEMENT

    Parent,  the Purchaser and  Healthdyne have entered  into the Stock Purchase
Agreement pursuant to which,  upon the terms and  subject to the conditions  set
forth  therein, Parent may direct Healthdyne to tender all, but not part, of the
Healthdyne Shares pursuant to and in accordance with the Offer. In the event the
Healthdyne Shares  shall not  have  been purchased  previously pursuant  to  the
Offer,  Healthdyne has agreed to sell the  Healthdyne Shares to Parent, upon the
satisfaction or  waiver  of the  conditions  set  forth in  the  Stock  Purchase
Agreement.

thereon arising out of Healthdyne's guaranty of the obligations of PSI under the
a Credit Agreement of  PSI's (the "Perinatal  Credit Agreement") and  Healthdyne
shall  have  obtained any  consent of  the lender  required under  the Perinatal
Credit Agreement.

    TERMINATION.   The Stock  Purchase  Agreement provides  that Parent  or  the
Purchaser  may terminate the  Stock Purchase Agreement if  (a) the Company shall
have breached  the  Merger  Agreement  in  any  material  respect,  or  (b)  any
representation  or warranty  of the  Company contained  in the  Merger Agreement
shall be untrue or incomplete in any material respect when made or at and as  of

                                       24
<PAGE>
Agreement  shall have been terminated by Parent in accordance with its terms, or
(e) any conditions  to Parent's  obligations to purchase  the Healthdyne  Shares
thereunder have not been satisfied or waived by June 30, 1994.

    The  Stock Purchase Agreement further provides that Healthdyne may terminate
the Stock Purchase  Agreement if (a)  any representation or  warranty of  Parent
contained  in  the Stock  Purchase Agreement  or the  Merger Agreement  shall be
untrue or  incomplete  in  any  material  respect  when  made  or  at  any  time
thereafter,  or  (b) Parent  shall have  terminated the  Offer or  terminated or
breached any material obligation  of Parent under the  Merger Agreement, or  (c)

Healthdyne's obligations  to sell  the  Healthdyne Shares  shall not  have  been
satisfied or waived on or before June 30, 1994.

    NEGOTIATIONS.   The Stock Purchase Agreement provides that until the earlier
to occur of  the purchase of  the Healthdyne  Shares or the  termination of  the
Stock Purchase Agreement or the Merger Agreement, Healthdyne shall not, directly
or  indirectly, solicit, encourage, or initiate  or engage in any discussions or
negotiations with, or provide any information to, any corporation,  partnership,
agent, financial adviser, person, or other entity or group (other than Parent or
an  affiliate  or  an associate  of  Parent  or an  officer,  employee  or other
authorized representative of Parent or  such affiliate or associate)  concerning
any  merger,  sale  of  substantial  assets,  sale  of  substantial  amounts  of
securities, or similar  transactions involving the  Company or any  sale of  the
Healthdyne  Shares. In  addition, pursuant  to the  terms of  the Stock Purchase
Agreement, Healthdyne has acknowledged  and consented to  the provisions of  the
Merger Agreement described herein under "The Merger Agreement--Other Offers" and
has agreed to comply with such provisions as though it were bound thereby.

    PROXY.  Pursuant to the Stock Purchase Agreement, Healthdyne has irrevocably
appointed,  during the term of the Stock Purchase Agreement, Parent as proxy for
Healthdyne to vote the Healthdyne Shares  which Healthdyne is entitled to  vote,
for  and in the  name, place and stead  of Healthdyne at  any annual, special or
other meeting of the shareholders of the Company and at any adjournments thereof
or pursuant to any consent in lieu  of a meeting, or otherwise, with respect  to
all  matters, except as may be prohibited by  applicable law at the time of such
vote.

    NON-COMPETITION.  Pursuant  to the  terms of the  Stock Purchase  Agreement,
neither  Healthdyne nor  any Healthdyne  affiliate shall,  for a  period of five
years from  the date  of the  acquisition  by the  Purchaser of  the  Healthdyne
Shares:  (a)  engage,  directly  or  indirectly,  in  or  control,  directly  or
indirectly,  any  Competitive  Business  in  the  United  States,  whether  such
engagement  or control  be as an  employer, owner, partner,  consultant or other
participant in any Competitive Business; or (b) assist others in engaging in any
Competitive Business in the United States; PROVIDED, HOWEVER, that Healthdyne or
any Healthdyne affiliate may engage in a Competitive Business to the extent that
such Competitive  Business arises  from  the acquisition  by Healthdyne  or  any
Healthdyne  affiliate of any  person engaged in a  Competitive Business and such
Competitive Business engaged in by such  acquired person amounts to only 10%  of
the  total revenue received by such acquired  person in the fiscal year prior to
such acquisition. Notwithstanding  the foregoing, Healthdyne  or any  Healthdyne
affiliate  may contract  or join  with other  persons in  one or  more groups or
alliances that provide a variety  of medical services, including Infusion  Care,
as long as neither Healthdyne nor any Healthdyne affiliate provides any Infusion
Care to or on behalf of such group or alliance. "Competitive Business" generally
means  any  business  engaged  wholly  or  partly  in  providing  Infusion Care,
including but not  limited to  any planning, research,  or licensing  activities
related  thereto (but excluding Infusion Care relating to obstetrics, gynecology
and  perinatal  care).   "Infusion  Care"  means   the  business  of   supplying
pharmaceuticals   or  medical   nutritional  therapies   to  patients,  doctors,
hospitals, insurance  companies  or other  persons  for  use on  patients  in  a
facility other than a hospital or critical care setting.

PLANS FOR THE COMPANY

    Parent  intends to conduct a detailed review  of the Company and its assets,
corporate structure,  dividend policy,  capitalization, operations,  properties,
policies,  management and personnel and to  consider what, if any, changes would
be desirable in light of the circumstances then existing, and reserves the right
to take such actions or effect such changes as it deems desirable. Such  changes
could   include  changes   in  the  Company's   business,  corporate  structure,
Certificate of  Incorporation,  By-Laws,  capitalization,  Board  of  Directors,
management  or dividend  policy. Upon consummation  of the Offer  or the closing
under  the  Stock  Purchase  Agreement,  the  Purchaser  intends  to  elect  its
representatives  in sufficient numbers to constitute  a majority of the Board of
Directors, as  provided  for  in  the Merger  Agreement.  The  Merger  Agreement
provides  that from and after the Effective Time, the directors of the Purchaser
at the Effective Time shall be  the directors of the Surviving Corporation,  and
the  officers of the Company at the Effective  Time shall be the officers of the
Surviving Corporation, and the Certificate  of Incorporation and By-Laws of  the
Company  will be the  Certificate of Incorporation and  By-Laws of the Surviving
Corporation.

    Except as otherwise  described in  this Offer  to Purchase,  Parent and  the
Purchaser have no current plans or proposals that would relate to, or result in,
any extraordinary corporate transaction involving the Company, such as a merger,
reorganization  or liquidation involving the Company or any of its subsidiaries,
a sale or transfer of a material amount  of assets of the Company or any of  its
subsidiaries,  any change in the Company's  capitalization or dividend policy or
any other  material change  in the  Company's business,  corporate structure  or
personnel.

APPRAISAL RIGHTS AND OTHER MATTERS

    Appraisal rights are not available in connection with the Offer and will not
be  available  in connection  with the  Merger.  The NJBCA  provides a  right of
dissent with respect to a plan of merger  or consolidation or a sale of all,  or
substantially  all, of  the assets  of the  corporation; however,  no such right
exists with respect to  shares (a) of  a class listed  on a national  securities
exchange  or which is held of  record by not less than  1,000 holders or (b) for
which, pursuant to the plan of merger or consolidation or a plan of dissolution,
the shareholder will  receive cash, shares  which will be  listed on a  national
securities  exchange or held by not less than 1,000 holders, or a combination of
such shares and cash.

    The Merger would have to comply with any applicable Federal law operative at
the time of its consummation. Rule 13e-3 under the Exchange Act is applicable to
certain "going private" transactions. The  Purchaser does not believe that  Rule
13e-3  will be applicable  to the Merger  unless the Merger  is consummated more
than one year after the termination of the Offer or provides for the payment  of
consideration with respect to the Shares that is less than that paid pursuant to
the  Offer. If  applicable, Rule 13e-3  would require, among  other things, that
certain financial  information concerning  the Company  and certain  information
relating to the fairness of the Merger and the consideration offered to minority
shareholders be filed with the Commission and disclosed to minority shareholders
prior to consummation of the Merger.

    13.   DIVIDENDS AND DISTRIBUTIONS.   If, on or after  the date of the Merger
Agreement, the Company should (a) split, combine or otherwise change the  Shares
or  its capitalization,  (b) acquire  currently outstanding  Shares or otherwise
cause a reduction  in the  number of  outstanding Shares  or (c)  issue or  sell
additional Shares (other than Shares reserved for issuance as of the date of the
Merger  Agreement under the Options and up to 10,000 Plan Shares), shares of any
other class  of  capital  stock,  other  voting  securities  or  any  securities
convertible  into, or rights, warrants or  options, conditional or otherwise, to
acquire, any of  the foregoing, then,  subject to the  provisions of Section  14
below,  the Purchaser, in its  sole discretion, may make  such adjustments as it
deems appropriate in the  Offer price and other  terms of the Offer,  including,
without limitation, the number or type of securities offered to be purchased.

    If, on or after the date of the Merger Agreement, the Company should declare
or  pay any cash dividend on the Shares  or other distribution on the Shares, or
issue with respect  to the  Shares any additional  Shares, shares  of any  other
class   of   capital  stock,   other   voting  securities   or   any  securities

                                       26
<PAGE>
convertible into, or rights, warrants  or options, conditional or otherwise,  to
acquire,  any  of the  foregoing, payable  or  distributable to  shareholders of
record on a date prior to the  transfer of the Shares purchased pursuant to  the
Offer  to the  Purchaser or  its nominee  or transferee  on the  Company's stock
transfer records, then, subject  to the provisions of  Section 14 below and  the
terms  of the Merger Agreement, (a) the price per Share payable by the Purchaser
pursuant to the Offer may, in the  sole discretion of the Purchaser, be  reduced
by  the amount of any such cash dividend  or cash distribution and (b) the whole
of any such  noncash dividend, distribution  or issuance to  be received by  the
tendering   shareholders  will  (i)  be  received  and  held  by  the  tendering
shareholders for  the  account of  the  Purchaser and  will  be required  to  be
promptly   remitted  and  transferred  by  each  tendering  shareholder  to  the
Depositary  for  the  account  of  the  Purchaser,  accompanied  by  appropriate
documentation  of  transfer,  or (ii)  at  the  direction of  the  Purchaser, be
exercised for the benefit of the Purchaser,  in which case the proceeds of  such
exercise will promptly be remitted to the Purchaser. Pending such remittance and
subject  to applicable  law, the  Purchaser will be  entitled to  all rights and
privileges as  owner of  any such  noncash dividend,  distribution, issuance  or
proceeds  and may withhold the entire Offer price or deduct from the Offer price
the amount  or  value  thereof, as  determined  by  the Purchaser  in  its  sole
discretion.

    Pursuant  to the  terms of the  Merger Agreement, the  Company is prohibited
from taking any of  the actions described in  the two preceding paragraphs,  and
nothing  herein shall constitute a  waiver by Parent or  the Purchaser of any of
its rights under the Merger Agreement  or a limitation of remedies available  to
Parent   or  Purchaser  for  any  breach  of  the  Merger  Agreement,  including
termination thereof.

    14.  CERTAIN CONDITIONS OF THE OFFER.  Notwithstanding any other term of the
Offer or the Merger Agreement, neither Parent nor the Purchaser will be required
to accept for payment or to pay  for any Shares tendered pursuant to the  Offer,
and  may  terminate or  amend the  Offer,  and may  postpone the  acceptance for
payment of  Shares pursuant  thereto,  unless on  the  Expiration Date  (a)  the
Minimum  Condition shall have  been satisfied, and (b)  any waiting period under
the HSR Act applicable  to the purchase  of Shares pursuant  to the Offer  shall
have  expired or been terminated. Furthermore, notwithstanding any other term of
the Offer or the Merger Agreement, Parent or the Purchaser shall not be required
to accept for  payment or to  pay for  any Shares not  theretofore accepted  for
payment  or paid for, and may terminate or  amend the Offer and may postpone the
acceptance for payment of Shares  pursuant thereto if, at  any time on or  after
the  date of the Merger  Agreement and before the  acceptance of such Shares for
payment or the payment therefor, any of the following conditions exists:

        (a) any statute, rule, regulation  or order shall be proposed,  enacted,
    entered  or deemed  applicable to  the Offer  or the  Merger (i)  making the
    purchase of, or  payment for,  some or  all of  the Shares  pursuant to  the
    Offer,  the Merger  Agreement or  the Stock  Purchase Agreement  illegal, or
    resulting in a material delay in the  ability of Parent or the Purchaser  to
    accept  for payment or pay  for some or all of  the Shares, or to consummate
    the Offer or Merger  or seeking to  obtain from the  Company, Parent or  the
    Purchaser  damages that would have a  material adverse effect on the Company
    and its  subsidiaries taken  as a  whole  or a  material adverse  effect  on
    National  Medical Care,  Inc. and  its subsidiaries  taken as  a whole, (ii)
    imposing material limitations on the ability of the Parent or the  Purchaser
    effectively  to acquire or hold  or to exercise full  rights of ownership of
    the Shares acquired by it, including the right to vote the Shares  purchased
    by  it on all matters properly presented to the shareholders of the Company,
    (iii) which would  require Parent  or the Purchaser  to dispose  of or  hold
    separate  any of the Shares or all or  any material portion of the assets or
    business of the Company and its  subsidiaries taken as a whole, or  National
    Medical  Care, Inc. and its subsidiaries taken  as a whole; or (iv) prohibit
    or materially limit  the ability  of the Parent  or any  direct or  indirect
    subsidiary  of  Parent  to own,  control  or operate  the  Company, National
    Medical Care, Inc., or  any of their respective  subsidiaries or all or  any
    material  portion of the businesses, operations or assets of the Company and
    its subsidiaries taken  as a whole  or National Medical  Care, Inc. and  its
    subsidiaries taken as a whole; or

                                       27
<PAGE>
        (b) any governmental or regulatory action or proceeding by or before any
    court,  government  or  governmental or  regulatory  authority,  domestic or
    foreign, shall  be  threatened, instituted  or  pending, or  any  action  or
    proceeding  by any other person, domestic or foreign, shall be instituted or
    pending, which  would  reasonably  be  expected to  result  in  any  of  the
    consequences referred to in clauses (i) through (iv) of paragraph (a) above;
    or

        (c)  the Company shall  not have complied in  all material respects with
    its agreements and covenants in the Merger Agreement, or its representations
    and warranties in the Merger Agreement, when  made or at and as of any  time
    thereafter, are untrue or incomplete in any material respect; or

        (d) Healthdyne shall not have complied in all material respects with its
    agreements   and  covenants  in   the  Stock  Purchase   Agreement,  or  its
    representations and warranties in the Stock Purchase Agreement, when made or
    at and as of any time thereafter,  are untrue or incomplete in any  material
    respect; or

        (e)  an offer shall have been publicly  proposed to be made or have been
    made on or after the date of this Offer to Purchase by another person or  by
    a  "group" of persons  as defined in  Section 13(d)(3) of  the Exchange Act,
    individually or in the aggregate, to purchase or exchange for cash or  other
    consideration  20% or  more of  the Shares, or  it shall  have been publicly
    disclosed or the Purchaser shall have learned that 20% or more of the Shares
    have been or are proposed to be acquired by another person or by a group  of
    persons; or

        (f) any change (or any development involving a prospective change) shall
    have occurred in the business, financial condition, results of operations or
    prospects  of  the Company  or any  of its  subsidiaries that  is materially
    adverse to the  Company and its  subsidiaries as  a whole (other  than as  a
    result   of  changes   in  conditions,   including  economic   or  political
    developments, applicable to  the business  of health care  generally or  the
    business  of home infusion  therapy generally not  having a disproportionate
    effect on the Company's business relative  to the effect of any such  change
    on other entities in the business of home infusion therapy); or

        (g)  there shall have occurred (i) any general suspension of trading in,
    or  limitation  on   prices  for,  securities   on  the  NYSE   or  in   the
    over-the-counter market, (ii) the declaration of a banking moratorium or any
    suspension  of payments in respect of banks  in the United States, (iii) the
    commencement of a war, armed hostilities or other international or  national
    calamity  directly or indirectly involving the United States, (iv) any event
    which, in the sole  judgment of Parent, affects  the extension of credit  by
    banks  or other financial institutions, (v) a material adverse change in the
    United States  exchange rates  or a  suspension of,  or limitation  on,  the
    markets  therefor,  (vi)  a decrease  of  more  than 25%  in  the  Dow Jones
    Industrial Average, or (vii) in the case of any of the foregoing existing at
    the time  of the  commencement  of the  Offer,  a material  acceleration  or
    worsening thereof; or

        (h)  the  Merger  Agreement shall  have  been terminated  or  amended to
    provide for the amendment or termination of the Offer; or

        (i) the  Company's  audited  financial statements  for  the  year  ended
    December  31, 1993, to  be included in  the Company's 1993  Annual Report on
    Form 10-K, shall be  materially and adversely  different from the  Company's
    Unaudited 1993 Financial Statements;

which  in  the  reasonable good  faith  judgment  of Parent,  in  any  such case
regardless of the  circumstances (including  any action or  omission by  Parent)
giving  rise to any such  conditions, makes it inadvisable  to proceed with such
acceptance for payment or makes it advisable to terminate or amend the Offer.

    The foregoing  conditions  are  for  the sole  benefit  of  Parent  and  the
Purchaser  and may  be asserted  by Parent and  the Purchaser  regardless of the
circumstances giving rise to any such conditions  or may be waived by Parent  or
the  Purchaser in whole or in  part, at any time and  from time to time in their

                                       28
<PAGE>
sole discretion. The failure by Parent or the Purchaser at any time to  exercise
any  of the foregoing rights shall not be  deemed a waiver of any such right and
each right shall be deemed  an on-going right that may  be asserted at any  time
and  from time to time. Any determination  by Parent or the Purchaser concerning
any events described in this Section 14 will be final and binding upon tendering
shareholders.

    15.  CERTAIN LEGAL MATTERS.  Except  as described in this Section 15,  based
on  a  review  of  publicly  available filings  made  by  the  Company  with the
Commission and  other publicly  available  information concerning  the  Company,
neither  Parent nor the Purchaser  is aware of any  license or regulatory permit
that appears to be material to the business of the Company and its subsidiaries,
taken as  a whole,  and that  might  be adversely  affected by  the  Purchaser's
acquisition  of  Shares  (and  the  indirect acquisition  of  the  stock  of the
Company's subsidiaries) as contemplated herein or, except as set forth below, of
any approval or other action by  any governmental authority or agency,  domestic
or  foreign, that would be  required for the acquisition  or ownership of Shares
(or the indirect acquisition of the stock of the Company's subsidiaries) by  the
Purchaser  as contemplated herein.  Should any such approval  or other action be
required, Parent and the Purchaser  currently contemplate that such approval  or
other  action will be sought.  While the Purchaser does  not currently intend to
delay the acceptance for payment of, or payment for, Shares tendered pursuant to
the Offer pending the outcome of any such matter, there can be no assurance that
any such approval  or other action,  if needed,  would be obtained  or would  be
obtained  without  substantial conditions  or that  failure  to obtain  any such
approval or  other  action might  not  result  in consequences  adverse  to  the
Company's  business or  that certain parts  of the Company's  business might not
have to be  disposed of  or other substantial  conditions complied  with in  the
event that such approvals were not obtained or such other actions were not taken
or  in order to  obtain any such approval  or other action.  If certain types of
adverse action  are taken  with  respect to  the  matters discussed  below,  the
Purchaser  could decline to accept  for payment or pay  for any Shares tendered.
See Section 14 for  certain conditions to the  Offer, including conditions  with
respect to litigation and governmental actions.

    HEALTH  CARE REGULATORY MATTERS.   The Federal government  and all states in
which the  Company  and  its subsidiaries  currently  operate  regulate  various
aspects of the business of the Company and its subsidiaries. The Company and its
subsidiaries  hold a number  of federal and  state licenses with  respect to the
operation of home health agencies and pharmacies and the possession and sale  of
controlled  substances.  The  purchase  of  Shares  pursuant  to  the  Offer may
constitute an  event giving  rise  to notice  and/or new  licensing  application
requirements,  and certain States may require  that the Purchaser meet specified
notice periods prior to  consummation of the Offer.  It is not anticipated  that
any such notice and/or new licensing requirements will delay the consummation of
the Offer.

    STATE  TAKEOVER  STATUTES.   The  Company  and certain  of  its subsidiaries
conduct business in  a number of  states throughout the  United States, some  of
which  have enacted "takeover" statutes that  purport, in varying degrees, to be
applicable  to  attempts  to  acquire   securities  of  corporations  that   are
incorporated  or  have  assets,  shareholders, executive  offices  or  places of
business in such states.

    In EDGAR V. MITE CORP., 457 U.S. 624 (1982), the Supreme Court of the United
States held  that  the Illinois  Business  Takeover Act,  which  involved  state
securities  laws that made the takeover  of certain corporations more difficult,
imposed  a  substantial  burden  on   interstate  commerce  and  therefore   was
unconstitutional. However, in CTS CORP. V. DYNAMICS CORP. OF AMERICA, 107 S. Ct.
1637  (1987), the Supreme Court of the United States held that a state may, as a
matter of  corporate law  and, in  particular, those  laws concerning  corporate
governance,  constitutionally disqualify a potential acquiror from voting on the
affairs of a  target corporation  without the  prior approval  of the  remaining
shareholders,  provided  that  such  laws  were  applicable  only  under certain
conditions.

    The New  Jersey Corporation  Takeover Bid  Disclosure Law  (the "New  Jersey
Takeover  Law") purports to  prohibit any "takeover bid"  to purchase any equity
security of a "target  company" (which is defined  to mean a corporation  either
organized under the laws of New Jersey or having its principal place of business
or  substantial portion of its total assets located within New Jersey) unless at
least

                                       29
<PAGE>
20 days before  such takeover bid  is made the  offeror has filed  with the  New
Jersey  Bureau  of  Securities  and  sent to  the  target  company  a disclosure
statement and such  takeover bid  has been permitted  to proceed  by the  Bureau
chief.  A  "takeover bid"  does  not include  an offer  as  to which  the target
company, acting through  its board  of directors, recommends  acceptance to  its
shareholders,  provided  that the  terms thereof,  including any  inducements to
officers and directors  that are not  made available to  all shareholders,  have
been  furnished  to  shareholders.  The New  Jersey  Takeover  Law  was declared
unconstitutional in  major part  by the  United States  District Court  for  the
District  of New Jersey in KENNECOTT CORP.  and KC DEVELOPMENT INC. V. SMITH, ET
AL., and the chief of  the New Jersey Bureau of  Securities has stated that  the
Bureau  is no  longer enforcing  any provisions of  the New  Jersey Takeover Law
except for the anti-fraud provisions. In any event, the Purchaser believes  that
the New Jersey Takeover Law does not by its terms apply to the Offer because the
Board  of Directors of the Company has unanimously recommended acceptance of the
Offer to the shareholders and the terms of the Offer, including any  inducements
to officers or directors of the Company that have not been made available to all
shareholders  of the  Company, have  been furnished  to the  shareholders of the
Company.

    To the extent that other state  takeover statutes might purport to apply  to
the  Offer or the Merger, the Purchaser believes that there are reasonable bases
for contesting such statutes. If any person should seek to apply any such  state
takeover  statute,  the  Purchaser  would  take  such  action  as  then  appears
desirable, which action may include challenging the validity or applicability of
any such statute in appropriate court proceedings. If it is asserted that one or
more takeover  statutes apply  to the  Offer, and  it is  not determined  by  an
appropriate  court that such statute or statutes  do not apply or are invalid as
applied  to  the  Offer,  the  Purchaser  might  be  required  to  file  certain
information with, or receive approvals from, the relevant state authorities, and
the  Purchaser  might be  unable  to purchase  or  pay for  the  Shares tendered
pursuant to the Offer,  or be delayed in  continuing or consummating the  Offer.
See Section 14.

    BUSINESS COMBINATIONS.  The New Jersey Shareholders Protection Act (the "New
Jersey  Act") has  the effect  of prohibiting  an "interested  shareholder" from
engaging in  a  business  combination  (including a  merger)  with  a  "resident
domestic  corporation" for  five years  after the  person becomes  an interested
shareholder, unless  the  resident  domestic corporation's  board  of  directors
approved  the  business  combination  before  the  person  became  an interested
shareholder. After the five-year period has elapsed, a business combination with
the interested shareholder may  be effected only if  in compliance with  certain
additional  provisions of the New Jersey  Act. A "resident domestic corporation"
is defined in the New Jersey Act as a corporation organized under New Jersey law
that has its principal executive offices  in New Jersey or significant  business
operations  in New  Jersey. The  Purchaser believes  that the  Company presently
qualifies as a "resident domestic corporation." A person who has acquired 10% or
more of the voting power of any such corporation is an "interested  shareholder"
under  the New Jersey Act. The Purchaser believes that it presently qualifies as
an "interested shareholder" since Healthdyne has granted, pursuant to the  Stock
Purchase Agreement, an irrevocable proxy to Parent to vote all Healthdyne Shares
with  respect to all matters.  Parent believes that the  New Jersey Act does not
prohibit the Merger  since the  Board of  Directors of  the Company  unanimously
approved  the Offer and the  Merger prior to the date  on which Parent became an
"interested shareholder" of the Company.

    ANTITRUST.  Under the provisions of the HSR Act applicable to the Offer, the
purchase of Shares under the Offer  may be consummated following the  expiration
of  a  15-calendar day  waiting period  following the  filing by  Parent, unless
Parent receives a  request for  additional information  or documentary  material
from  the Antitrust  Division or  the FTC.  Parent expects  to make  such filing
during the week of  March 14, 1994. See  "Section 12 -- Additional  Agreements."
If,  within the initial 15-day waiting  period, either the Antitrust Division or
the FTC requests additional information  or material from Parent concerning  the
Offer,  the waiting period will be extended  and would expire at 11:59 p.m., New
York City time, on  the tenth day  after the date  of substantial compliance  by
Parent with such request. Only one extension of the waiting period pursuant to a
request  for additional  information is authorized  by the  HSR Act. Thereafter,
such waiting period may be extended only  by court order or with the consent  of
Parent.

                                       30
<PAGE>
    The  provisions of the HSR Act would  similarly apply to any purchase of the
Healthdyne Shares pursuant to the Stock Purchase Agreement (other than purchases
effected through  a tender  pursuant  to the  Offer),  except that  the  initial
waiting period would expire 30 days following the filing of HSR Act Notification
Forms  by Parent  and the  Company and a  request for  additional information or
material from Parent  or the Company  during the initial  30-day waiting  period
would  extend the waiting period until 11:59 p.m. New York City Time on the 20th
day after the date of substantial compliance by Parent and the Company with such
request. Parent  and the  Company expect  to file  HSR Notification  Forms  with
respect  to the Stock Purchase Agreement during  the week of March 14, 1994. If,
as is  expected, the  purchase  of Shares  contemplated  by the  Stock  Purchase
Agreement is effected through a tender of such Shares pursuant to the Offer, the
HSR  requirements applicable to the Offer described in the prior paragraph would
apply rather than the requirements described in this paragraph.

    The Merger would not require an additional  filing under the HSR Act if  the
Purchaser  owns 50% or more of the outstanding  Shares at the time of the Merger
or if  the Merger  occurs  within one  year after  the  HSR Act  waiting  period
applicable to the Offer expires or is terminated.

    The  FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the Purchaser's proposed  acquisition
of  the Company. At any time before  or after the Purchaser's purchase of Shares
pursuant to the Offer, the Antitrust Division or the FTC could take such  action
under  the  antitrust laws  as it  deems  necessary or  desirable in  the public
interest, including seeking  to enjoin the  purchase of Shares  pursuant to  the
Offer  or the consummation  of the Merger  or seeking the  divestiture of Shares
acquired by the Purchaser or the divestiture of substantial assets of Parent  or
its  subsidiaries, or the Company or  its subsidiaries. Private parties may also
bring legal actions under the antitrust laws under certain circumstances.  There
can  be no assurance that a challenge to the Offer on antitrust grounds will not
be made or, if such a challenge is  made, of the result thereof. See Section  14
for  certain conditions of the Offer, including conditions with respect to court
and governmental actions.

    16.  FEES AND EXPENSES.  The Purchaser  has retained D. F. King & Co.,  Inc.
to  act as the Information  Agent and Chemical Bank to  act as the Depositary in
connection with the Offer.  The Information Agent and  the Depositary each  will
receive  reasonable and customary compensation for their services, be reimbursed
for certain reasonable out-of-pocket expenses and be indemnified against certain
liabilities and expenses in connection therewith, including certain  liabilities
under the Federal securities laws.

    Neither  Parent nor the  Purchaser will pay  any fees or  commissions to any
broker or  dealer  or  other  person (other  than  the  Information  Agent)  for
soliciting tenders of Shares pursuant to the Offer. Brokers, dealers, commercial
banks  and trust  companies will  be reimbursed  by the  Purchaser for customary
mailing and handling expenses incurred by  them in forwarding material to  their
customers.

    17.   MISCELLANEOUS.   The Offer is not  being made to  (nor will tenders be
accepted from or on behalf  of) holders of Shares  in any jurisdiction in  which
the  making of the  Offer or the  acceptance thereof would  not be in compliance
with the laws of such jurisdiction. Neither the Purchaser nor Parent is aware of
any jurisdiction in which  the making of  the Offer or the  tender of Shares  in
connection  therewith  would  not  be  in  compliance  with  the  laws  of  such
jurisdiction. To the extent the Purchaser  or Parent becomes aware of any  state
law  that would  limit the class  of offerees  in the Offer,  the Purchaser will
amend the Offer and,  depending on the  timing of such  amendment, if any,  will
extend  the  Offer  to provide  adequate  dissemination of  such  information to
holders of Shares prior to the expiration of the Offer.

    No person  has  been authorized  to  give any  information  or to  make  any
representation  on behalf of the Purchaser or  Parent not contained herein or in
the  Letter  of  Transmittal  and,  if  given  or  made,  such  information   or
representation must not be relied upon as having been authorized.
                            ------------------------

    Parent  and the  Purchaser have filed  with the Commission  a Schedule 14D-1
pursuant to Rule  14d-3 under  the Exchange Act,  furnishing certain  additional
information with respect to the

                                       31
<PAGE>
Offer.  The Company has filed  with the Commission a Solicitation/Recommendation
Statement on  Schedule 14D-9,  together with  exhibits, pursuant  to Rule  14d-9
under  the Exchange  Act, setting forth  its recommendation with  respect to the
Offer and the reasons for such recommendation, and furnishing certain additional
related information. The  Schedule 14D-1 and  any amendments thereto,  including
exhibits,  may be examined, and copies may  be obtained, in the manner set forth
in Section 9  hereof (except that  they will  not be available  at the  regional
offices of the Commission).

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY.

Ladies and Gentlemen:

    The  undersigned  hereby tenders  to Company  N Merger  Corp., a  New Jersey
corporation ("Purchaser")  wholly  owned  by W.  R.  Grace  & Co.,  a  New  York
corporation ("Grace"), the above described shares of common stock (the "Shares")
of  Home Nutritional Services,  Inc., a New  Jersey corporation (the "Company"),
pursuant to Purchaser's offer to purchase  all outstanding Shares at a price  of
$7.85  per Share,  net to the  seller in  cash (the "Purchase  Price"), upon the
terms and subject to  the conditions set  forth in the  Offer to Purchase  dated
March   10,  1994  (the  "Offer  to  Purchase"),  receipt  of  which  is  hereby
acknowledged, and in this Letter  of Transmittal (which together constitute  the
"Offer").

    Subject  to,  and  effective  upon, acceptance  for  payment  of  the Shares
tendered herewith in accordance with the terms and subject to the conditions  of
the  Offer, the undersigned hereby  sells, assigns and transfers  to or upon the
order of Purchaser,  all right,  title and  interest in  and to  all the  Shares
tendered  hereby (and any and all other Shares, dividends, distributions, rights
and  other  securities  and  property  issued  or  issuable  or  distributed  or
distributable  in  respect  thereof on  or  after March  4,  1994 (collectively,
"Distributions")), and irrevocably constitutes  and appoints the Depositary  the
true  and lawful agent  and attorney-in-fact of the  undersigned with respect to
such Shares (and any Distributions) with full power of substitution (such  power
of  attorney being deemed to  be an irrevocable power  coupled with an interest)
to: (i)  deliver  certificates  for  such Shares  (and  any  Distributions),  or
transfer  ownership of such Shares (and  any Distributions) on the account books
maintained by a Book-Entry Transfer Facility, together in either such case  with
all accompanying evidences of transfer and authenticity, to or upon the order of
Purchaser,  upon receipt by  the Depositary, as the  undersigned's agent, of the
Purchase Price; (ii) present such Shares (and any Distributions) for transfer on
the books of the Company; and (iii) receive all benefits and otherwise  exercise
all  rights of beneficial ownership of  such Shares (and any Distributions), all
in accordance with  the terms  of the  Offer. Purchaser  expressly reserves  the
right  to  transfer  or  assign  to Purchaser  or  one  or  more  of Purchaser's
subsidiaries or  affiliates the  right to  purchase all  or any  portion of  the
Shares  tendered  hereby  (and  any  Distributions),  but  no  such  transfer or
assignment will relieve Purchaser of its obligations hereunder or prejudice  the
rights  of the undersigned to receive payment for Shares validly tendered hereby
and accepted for payment pursuant to the Offer.

    The undersigned hereby  irrevocably appoints  Brian J. Smith  and Robert  B.
Lamm,  and each of them, attorneys-in-fact  and proxies of the undersigned, each
with full power of substitution,  to vote in such  manner as each such  attorney
and  proxy or the substitute  for any such attorney and  proxy shall in the sole
discretion of  each  such attorney  and  proxy  deem proper  and  otherwise  act
(including  pursuant to written consent) with respect to all the Shares tendered
hereby (and any Distributions) that have been accepted for payment by  Purchaser
prior  to the time of such vote or other action that the undersigned is entitled
to vote at any meeting of shareholders (whether annual or special and whether or
not an  adjourned meeting)  of  the Company,  or consent  in  lieu of  any  such
meeting, or otherwise. This proxy is irrevocable and is granted in consideration
of,  and is effective upon, Purchaser's oral or written notice to the Depositary
of its acceptance for payment of such Shares in accordance with the terms of the
Offer. Such acceptance for payment shall  revoke all prior proxies given by  the
undersigned at any time with respect to such Shares (and any Distributions), and
no  subsequent proxies may  be given (and  if given will  not be effective) with
respect thereto by the  undersigned. Purchaser expressly  reserves the right  to
require  that, in order for Shares to  be validly tendered, immediately upon the
acceptance for payment of such Shares (and any Distributions), Purchaser is able
to  exercise  full  voting  rights  with   respect  to  such  Shares  (and   any
Distributions).

    The undersigned hereby represents and warrants that: (i) the undersigned has
full  power  and  authority to  tender,  sell,  assign and  transfer  the Shares
tendered hereby (and any Distributions) and (ii) when the same are accepted  for
payment  by Purchaser, Purchaser will  acquire good, marketable and unencumbered
title  thereto,  free  and  clear  of  all  liens,  restrictions,  charges   and
encumbrances,  and  the same  will  not be  subject  to any  adverse  claim. The
undersigned, upon request, will execute  and deliver any signature guarantee  or
additional  documents deemed by  the Depositary or Purchaser  to be necessary or
desirable to complete or confirm the sale, assignment and transfer of the Shares
tendered hereby (and any Distributions).

    In addition,  the  undersigned shall  promptly  remit and  transfer  to  the
Depositary  for  the  account  of Purchaser  any  Distributions,  accompanied by
appropriate  documentation  of   transfer,  and  pending   such  remittance   or
appropriate  assurance thereof,  Purchaser shall be  entitled to  all rights and
privileges as owner of such Distributions  and may withhold the entire  Purchase
Price  or  deduct  from the  Purchase  Price  the amount  or  value  thereof, as
determined by Purchaser in its sole discretion.

    All authority  conferred  or  agreed  to be  conferred  by  this  Letter  of
Transmittal shall not be affected by, and shall survive, the death or incapacity
of  the undersigned,  and any obligation  of the undersigned  hereunder shall be
binding upon the successors, assigns, heirs, executors, administrators, trustees
in bankruptcy and legal representatives of the undersigned. Except as stated  in
the Offer to Purchase, this tender is irrevocable, provided that Shares tendered
pursuant  to the Offer may be withdrawn at any time prior to the Expiration Date
and, unless  theretofore  accepted for  payment  by the  Purchaser  as  provided
herein, may also be withdrawn at any time after May 8, 1994.

    The  undersigned  understands that  the acceptance  for payment  of tendered
Shares by Purchaser pursuant to any of the procedures described in "Section 2 --
Procedure for Tendering Shares" of the Offer to Purchase and in the instructions
hereto will constitute a binding agreement between the undersigned and Purchaser
upon the  terms and  subject to  the conditions  of the  Offer. The  undersigned
recognizes  that under certain circumstances set forth in the Offer to Purchase,
Purchaser may not be required to accept  for payment any of the Shares  tendered
hereby.

    Unless  otherwise  indicated  herein under  "Special  Payment Instructions,"
please issue the check for the Purchase Price and/or return any certificates for
Shares not tendered or accepted for  payment in the name(s) of the  undersigned.
Similarly,  unless  otherwise indicated  under "Special  Delivery Instructions,"
please mail the check for the Purchase Price and/or return any certificates  for
Shares  not tendered  or accepted  for payment  (and accompanying  documents, as
appropriate) to the undersigned at the address shown above under "Description of
Tendered Shares." In the event that  both the Special Delivery Instructions  and
the  Special Payment Instructions are completed,  please issue the check for the
Purchase Price  and/or  return  any  certificates for  Shares  not  tendered  or
accepted  for payment in the name of,  and deliver said check and/or return such
certificates to, the person or persons so indicated. Unless otherwise  indicated
under  "Special  Payment Instructions,"  in the  case of  delivery of  shares by
book-entry  transfer,  please  credit  the   account  maintained  at  the   Book
Entry-Transfer  Facility  indicated  above  with  any  Shares  not  accepted for
payment. The undersigned recognizes that Purchaser has no obligation pursuant to
the Special Payment  Instructions to transfer  any Shares from  the name of  the
registered  holder thereof if Purchaser  does not accept for  payment any of the
Shares so tendered.

Transmittal  (or  manually  signed  facsimile hereof)  and  any  other documents

    Shareholders whose certificates are not immediately available or who  cannot

and duly  executed Notice  of  Guaranteed Delivery,  substantially in  the  form
provided  by  Purchaser, must  be  received by  the  Depositary, either  by hand

    No  alternative, conditional or  contingent tenders will  be accepted and no
fractional Shares will be purchased. All tendering shareholders, by execution of
this Letter of Transmittal (or facsimile hereof), waive any right to receive any
notice of the acceptance of their Shares for payment.

    3.   INADEQUATE SPACE.   If  the space  provided herein  is inadequate,  the
certificate  numbers and/or the number of Shares  should be listed on a separate
signed schedule attached hereto.

    4.  PARTIAL TENDERS (not applicable to shareholders who tender by book-entry
transfer).  If fewer than all the Shares evidenced by any certificate  submitted
are  to be tendered, fill in the number of Shares that are to be tendered in the
box entitled "Number of Shares Tendered."  In such case, as soon as  practicable
after  the Expiration Date,  new certificate(s) for the  remainder of the Shares
that were  evidenced by  your old  certificate(s) will  be sent  to you,  unless
otherwise  provided in  the appropriate box  of this Letter  of Transmittal. All
Shares represented by certificates delivered to the Depositary will be deemed to

tendered hereby, the signature(s)  must correspond exactly  with the name(s)  as
written on the face of the certificate(s) without alteration, enlargement or any
change whatsoever.

    If  any of  the Shares tendered  hereby are owned  of record by  two or more
joint owners, all such owners must sign this Letter of Transmittal.

    If any  tendered  Shares  are  registered  in  different  names  on  several
certificates, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of certificates.

    If this Letter of Transmittal or any certificates or stock powers are signed
by  a  trustee,  executor,  administrator,  guardian,  attorney-in-fact,  agent,
officer of a corporation or other person acting in a fiduciary or representative
capacity, such  person should  so  indicate when  signing, and  proper  evidence
satisfactory  to the  Purchaser of  such person's  authority to  so act  must be
submitted.

    When this Letter of Transmittal is signed by the registered owner(s) of  the
Shares  listed  and  transmitted  hereby,  no  endorsements  of  certificates or
separate powers  are required  unless  payment or  certificates for  Shares  not
tendered  or purchased are  to be issued  to a person  other than the registered
owner(s), in which case signatures on such certificates or stock powers must  be
guaranteed by an Eligible Institution.

    If  this  Letter  of Transmittal  is  signed  other than  by  the registered
owner(s) of the Shares listed, the certificates must be endorsed or  accompanied
by  appropriate stock powers, in either case signed exactly as the name or names
of the registered owner or owners appear on the certificates, and signatures  on
such  certificates or  stock powers  are required and  must be  guaranteed by an
Eligible Institution.

    6.   STOCK TRANSFER  TAXES.   Except as  set forth  in this  Instruction  6,
Purchaser  will pay or cause to be paid any stock transfer taxes with respect to
the transfer and sale of Shares to it,  or its order, pursuant to the Offer.  If
payment  of the Purchase Price  is to be made to,  or if certificates for Shares
not tendered or purchased are to be registered in the name of, any person  other
than  the person(s) signing this Letter of  Transmittal, the amount of any stock
transfer taxes (whether imposed  on the registered owner  or such other  person)
payable  on account of the  transfer to such other  person will be deducted from
Purchase Price unless  satisfactory evidence  of the  payment of  such taxes  or
exemption therefrom is submitted.

    EXCEPT  AS PROVIDED  IN THIS  INSTRUCTION 6,  IT WILL  NOT BE  NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO  THE CERTIFICATES LISTED IN THIS LETTER  OF
TRANSMITTAL.

    7.    SPECIAL  PAYMENT  AND  DELIVERY  INSTRUCTIONS.    If  a  check  and/or
certificates for unpurchased Shares  are to be  issued in the  name of a  person
other than the signer of this Letter of Transmittal, or if a check is to be sent
and/ or such certificates are to be returned to someone other than the signer of
this  Letter of Transmittal  or to an  address other than  that shown above, the
appropriate  box(es)  on  this  Letter  of  Transmittal  should  be   completed.

W-9, which is provided under "Important  Tax Information" below, and to  certify
that  the shareholder  (or other  payee) is  not subject  to backup withholding.
Failure to provide the  information on the Substitute  Form W-9 may subject  the
tendering  shareholder (or other payee) to 31% Federal income tax withholding on
the payment of the Purchase Price. The box in Part 3 of the Substitute Form  W-9
may be checked if the tendering shareholder (or other payee) has not been issued
a  TIN and  has applied  for a TIN  or intends  to apply for  a TIN  in the near
future. If the box in Part 3 is checked and the Depositary is not provided  with
a  TIN by the time of payment, the  Depositary will withhold 31% on all payments
of the Purchase Price.

    11.  LOST OR DESTROYED CERTIFICATES.  If any certificate representing Shares
has been lost or destroyed, the stockholder should promptly notify Trust Company
Bank at  (404) 588-7817.  The shareholder  will  then be  instructed as  to  the
procedure  to be followed in order to replace the certificate(s). This Letter of
Transmittal and  related  documents cannot  be  processed until  procedures  for
replacing lost or destroyed certificates have been followed.

    IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE HEREOF), TOGETHER WITH
CERTIFICATES  OR  CONFIRMATION OF  BOOK-ENTRY  TRANSFER AND  ALL  OTHER REQUIRED
DOCUMENTS OR  THE  NOTICE  OF  GUARANTEED DELIVERY,  MUST  BE  RECEIVED  BY  THE
DEPOSITARY ON OR PRIOR TO THE EXPIRATION DATE.

                           IMPORTANT TAX INFORMATION

    Under  Federal  income  tax law,  a  shareholder whose  tendered  Shares are
accepted  for  payment  is  required   to  provide  the  Depositary  with   such
shareholder's  current TIN on Substitute Form  W-9 below. If such shareholder is
an individual, the TIN is his social  security number. If the Depositary is  not
provided  with the correct TIN, the shareholder or other payee may be subject to
a $50 penalty  imposed by the  Internal Revenue Service.  In addition,  payments
that  are  made  to such  shareholder  or  other payee  with  respect  to Shares
purchased pursuant to the Offer may be subject to backup withholding.

    Certain shareholders (including, among others, all corporations and  certain
foreign  individuals) are not subject to  these backup withholding and reporting
requirements. In  order  for  a  foreign individual  to  qualify  as  an  exempt
recipient,  that shareholder must submit to  the Depositary a properly completed
Internal Revenue Service Form W-8, signed under penalties of perjury,  attesting
to  that  shareholder's exempt  status.  A Form  W-8  can be  obtained  from the
Depositary.  See  the  enclosed   "Guidelines  for  Certification  of   Taxpayer
Identification Number on Substitute Form W-9" for additional instructions.

    If backup withholding applies, the Depositary is required to withhold 31% of
any payment made to the shareholder or other payee. Backup withholding is not an
additional  tax. Rather, the Federal income  tax liability of persons subject to
backup withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a  refund may be obtained from the  Internal
Revenue Service.

PURPOSE OF SUBSTITUTE FORM W-9

    To  prevent backup  withholding on payments  made to a  shareholder or other
payee with respect to Shares purchased pursuant to the Offer, the shareholder is
required to notify the Depositary of  the shareholder's current TIN (or the  TIN
of  any  other payee)  by completing  the  form below,  certifying that  the TIN
provided on the  Substitute Form  W-9 is correct  (or that  such shareholder  is
awaiting  a TIN),  and that  (i) the  shareholder has  not been  notified by the
Internal Revenue Service that the  shareholder is subject to backup  withholding
as  a result of failure to report all interest or dividends or (ii) the Internal
Revenue Service has notified the shareholder  that the shareholder is no  longer
subject to backup withholding.

WHAT NUMBER TO GIVE THE DEPOSITARY

    The shareholder is required to give the Depositary the TIN (e.g., the social
security  number or Federal employer identification  number) of the record owner
of the Shares. If  the Shares are registered  in more than one  name or are  not
registered in the name of the actual owner, consult the enclosed "Guidelines for
Certification  of  Taxpayer Identification  Number on  Substitute Form  W-9" for
additional guidelines on which number to report.

CERTAIN CONDITIONS, THE MERGER OF THE  PURCHASER WITH AND INTO THE COMPANY  (THE

TENDERED AND NOT WITHDRAWN PRIOR TO THE  EXPIRATION OF THE OFFER THAT NUMBER  OF
SHARES  REPRESENTING  AT LEAST  A MAJORITY  OF THE  TOTAL NUMBER  OF OUTSTANDING

OF THE OFFER. THE BOARD  OF DIRECTORS OF THE COMPANY,  BY UNANIMOUS VOTE OF  THE

Expiration Date (as defined in the Offer to Purchase) and not properly withdrawn
if, as and when the Purchaser gives oral or written notice to the Depositary  of

all cases, payment for Shares purchased pursuant to the Offer will be made  only
after  timely receipt by the Depositary  of certificates evidencing such Shares,

transfer shall be made, all in accordance with the instructions set forth in the

comply with the book-entry transfer procedures or deliver all required documents
to  the Depositary on a timely basis, a  tender may be effected by following the
guaranteed  delivery  procedures  specified  in  "Section  2  --  Procedure  for
Tendering Shares" of the Offer to Purchase.

    The  Purchaser will,  upon request,  reimburse brokers,  dealers, commercial
banks and trust companies for reasonable and necessary costs incurred by them in

                     a wholly owned subsidiary of

                          W. R. GRACE & CO.

owned by W. R. Grace & Co., a New York corporation ("Parent"), is offering to

Home Nutritional Services, Inc., a New Jersey corporation (the "Company"), at

conditions set forth in the Offer to Purchase dated March 10, 1994 and in the
related Letter of Transmittal (which together constitute the "Offer").

           THE OFFER EXPIRES AT 12:00 MIDNIGHT, NEW YORK CITY
           TIME, ON WEDNESDAY, April 6, 1994, UNLESS EXTENDED.

   THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER THAT NUMBER OF
SHARES REPRESENTING AT LEAST A MAJORITY OF THE TOTAL NUMBER OF OUTSTANDING
SHARES, ASSUMING FULL EXERCISE OF ALL OPTIONS WITH AN EXERCISE PRICE OF LESS
THAN $7.85 PER SHARE AND ISSUANCE OF 10,000 SHARES PURSUANT TO THE COMPANY'S
EMPLOYEE STOCK PURCHASE PLAN, OR ALL OF THE CONDITIONS TO CLOSING UNDER
THE STOCK PURCHASE AGREEMENT (AS DEFINED BELOW) BEING SATISFIED OR IRREVOCABLY
WAIVED AND THE PARTIES THERETO AGREEING TO CLOSE THE TRANSACTIONS CONTEMPLATED
THEREUNDER IMMEDIATELY AFTER CONSUMMATION OF THE OFFER. THE BOARD OF DIRECTORS
OF THE COMPANY, BY UNANIMOUS VOTE OF THE DIRECTORS PRESENT, HAS DETERMINED
THAT THE MERGER AGREEMENT (AS DEFINED BELOW) AND THE TRANSACTIONS CONTEMPLATED
THEREBY, INCLUDING THE OFFER AND THE MERGER (AS DEFINED BELOW), ARE FAIR TO
AND IN THE BEST INTEREST OF THE COMPANY AND ITS SHAREHOLDERS, HAS APPROVED THE
OFFER AND THE MERGER AND RECOMMENDS THAT THE SHAREHOLDERS OF THE COMPANY
ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO THE OFFER.

   The Offer is being made pursuant to an Agreement and Plan of Merger dated
as of March 4, 1994 (the "Merger Agreement") by and among the Company, the
Purchaser and Parent, which provides, among other things, for the making of
the Offer and, following consummation of the Offer and the satisfaction or
waiver of certain conditions, the merger of the Purchaser with and into the
Company (the "Merger"), with the Company surviving the Merger as a wholly
owned subsidiary of Parent. On the effective date of the Merger, each
outstanding Share will be converted into the right to receive $7.85 in cash,
without interest. Pursuant to the terms and subject to the conditions set
forth in a Stock Purchase Agreement dated as of March 4, 1994 (the "Stock
Purchase Agreement"), by and among the Purchaser, Healthdyne, Inc.
("Healthdyne") and Parent, Healthdyne, the beneficial owner of 7,800,000
Shares, constituting approximately 65% of the total number of outstanding
Shares, has agreed to sell such Shares to the Purchaser, and, at the request
of the Purchaser, shall tender such Shares in the Offer.

   For purposes of the Offer, the Purchaser shall be deemed to have accepted
for payment, and thereby purchased, Shares properly tendered to the Purchaser
and not withdrawn as, if and when the Purchaser gives oral or written notice
to the Depositary of the Purchaser's acceptance for payment of such Shares.
Upon the terms and subject to the conditions of the Offer, payment for Shares
purchased pursuant to the Offer will be made by deposit of the purchase price
therefor with the Depositary, which will act as agent for tendering
shareholders for the purpose of receiving payment from the Purchaser and
transmitting payment to tendering shareholders. Under no circumstances will
interest be paid by the Purchaser on the purchase price of the Shares,
regardless of any delay in making such payment. In all cases, payment for
Shares purchased pursuant to the Offer will be made only after timely receipt
by the Depositary of (a) certificates for such Shares or  confirmation of
book-entry transfer of such Shares into the Depositary's account at a
Book-Entry Transfer Facility (as defined in the Offer to Purchase) pursuant to
the procedures set forth in Section 2 of the Offer to Purchase, (b) a properly
completed and duly executed Letter of Transmittal (or facsimile thereof) with
any required signature guarantees and(c) any other documents required by the
Letter of Transmittal.

   The term "Expiration Date" means 12:00 Midnight, New York City time, on
Wednesday, April 6, 1994, unless and until the Purchaser, in its sole
discretion, shall have extended the period of time during which the Offer is
open, in which event the term "Expiration Date" shall mean the latest time and
date on which the Offer, as so extended by the Purchaser, shall expire. The
Purchaser expressly reserves the right, in its sole discretion, at any time or
from time to time and regardless of whether or not any of the events set forth
in Section 14 of the Offer to Purchase shall have occurred or shall have been
determined by the Purchaser to have occurred, to extend the period of time
during which the Offer is open and thereby delay acceptance for payment of,
and the payment for, any Shares, by giving oral or written notice of such
extension to the Depositary. The Purchaser shall not have any obligation to
pay interest on the purchase price for tendered Shares in the event the
Purchaser exercises its right to extend the period of time during which the
Offer is open. There can be no assurance that the Purchaser will exercise its
right to extend the Offer. Any such extension will be followed by a public
announcement thereof no later than 9:00 A.M., New York City time, on the next
business day after the previously scheduled Expiration Date. During any such
extension, all Shares previously tendered and not withdrawn will remain
subject to the Offer, subject to the right of a tendering shareholder to
withdraw such shareholder's Shares, as set forth in the Offer to Purchase.

   Shares tendered pursuant to the Offer may be withdrawn at any time prior to
12:00 Midnight, New York City time, on Wednesday, April 6, 1994 (or, if the
Purchaser shall have extended the period of time during which the Offer is
open, the latest time and date at which the Offer, as so extended by the
Purchaser, shall expire) and, unless theretofore accepted for payment and paid
for, may also be withdrawn after May 8, 1994. For a withdrawal to be
effective, a written or facsimile transmission notice of withdrawal must be
timely received by the Depositary at one of its addresses set forth on the
back cover of the Offer to Purchase and must specify the name of the person
having tendered the Shares to be withdrawn, the number of Shares to be
withdrawn and the name of the registered holder, if different from the name of
the person who tendered the Shares. If certificates for Shares have been
delivered or otherwise identified to the Depositary, then, prior to the
physical release of such certificates, the serial numbers shown on such
certificates must be submitted to the Depositary and the signatures on the
notice of withdrawal must be guaranteed by an Eligible Institution (as defined
in Section 2 of the Offer to Purchase) except, with respect to signature
guarantees, in the case of Shares tendered by an Eligible Institution. If
Shares have been delivered pursuant to the procedures for book-entry transfer
as set forth in Section 2 of the Offer to Purchase, any notice of withdrawal
must also specify the name and number of the account at the appropriate
Book-Entry Transfer Facility (as defined in Section 2 of the Offer to
Purchase) to be credited with the withdrawn Shares and must otherwise comply
with such Book-Entry Transfer Facility's procedures. Withdrawals of tenders of
Shares may not be rescinded, and any Shares properly withdrawn will thereafter
be deemed not validly tendered for purposes of the Offer. However, withdrawn
Shares may be retendered by again following one of the procedures described in
Section 2 of the Offer to Purchase at any time prior to the expiration of the
Offer. All questions as to the form and validity (including time of receipt)
of notices of withdrawal will be determined by the Purchaser in its sole
discretion, and its determination will be final and binding.

   The Offer to Purchase and the related Letter of Transmittal and other
relevant materials will be mailed to record holders of Shares and furnished to
brokers, dealers, commercial banks, trust companies and similar persons whose
names, or the names of whose nominees, appear on the shareholder list or, if
applicable, who are listed as participants in a clearing agency's security
position listings, for subsequent transmittal to beneficial owners of Shares.

   The information required to be disclosed by Rule 14d-6(e)(1)(vii) of the
General Rules and Regulations under the Securities Exchange Act of 1934, as
amended, is contained in the Offer to Purchase and is incorporated herein by
reference.

          BOCA RATON, Fla. and MARIETTA, Ga., March 4, 1994--W. R. Grace & Co.
(NYSE:  GRA) and Home Nutritional Services, Inc. (OTC:  HNSI), a national
provider of home infusion therapy services, jointly announced that they have
entered into a definitive agreement under which a Grace subsidiary would acquire
all of the outstanding shares of Home Nutritional Services (HNS) for $7.85 per
share in cash.  There are approximately 11.5 million HNS shares currently
outstanding.

          In accordance with the agreement, Grace will commence a tender offer

          The Board of Directors of HNS has approved the offer and determined
that the price to be paid in the transaction is fair to its stockholders, and
has recommended that HNS' stockholders accept the offer and tender their shares.
The Board had been advised by Dillon, Read & Co. Inc. that the $7.85 per share
price is fair to the stockholders of HNS from a financial point of view.

          Following completion of the transaction, HNS will operate as part of
Grace's NMC Homecare unit, the third largest national provider of home infusion
services.  As an integrated home care provider, NMC Homecare also offers
respiratory therapy nationwide and home nursing in California.

          According to Peter Spears, NMC Homecare president, "The addition of
HNS represents a significant opportunity to expand our services and improve our
operating efficiency to more successfully compete in the growing managed care
environment."  The acquisition will strengthen a number of NMC Homecare's
approximately one hundred infusion locations while adding locations in 15 new
markets.

          Grace, based in Boca Raton, Fla., is the world's largest specialty
chemicals company with a leadership position in specialized health care.

          Home Nutritional Services, a national provider of home infusion
therapies and related alternate site services, is one of the oldest and largest

centers, 17 satellite facilities, and 37 additional sites of services.  HNS is

     WHEREAS, the Board of Directors of the Purchaser and the Board of Directors
of the Company have each determined that it is advisable to merge the Company
with Merger Sub (the "Merger") pursuant to this Merger Agreement, with the
result that the holders of the outstanding Common Stock of the Company, no par
value (the "Shares"), shall receive a payment in cash for each Share as provided
in this Merger Agreement and the Company shall become a wholly owned subsidiary
of the Purchaser; and

     WHEREAS, the Purchaser and Healthdyne, Inc. (the "Seller") have entered
into a Stock Purchase Agreement dated the date hereof (the "Stock Purchase
Agreement"), providing for the sale by the Seller to the Purchaser of certain
Shares;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained, the Purchaser, Merger Sub and the Company hereby agree as
follows:

     1.   THE OFFER

     1.1  THE OFFER.  Provided that nothing shall have occurred which would
result in a failure to satisfy any of the conditions set forth in the Appendix
hereto, the Purchaser (or a direct or indirect wholly owned subsidiary of the
Purchaser, which may include Merger Sub) shall promptly, and in no event later
than one business day after the date hereof, publicly announce, and within five
business days thereafter commence (within the meaning of Rule 14d-2 under the
Securities Exchange Act of 1934, as amended (the "Exchange Act")) a tender offer
for any and all Shares at a price of $7.85 per Share net to the seller in cash
(the "Offer") and, subject to the conditions set forth in such Appendix, shall
consummate the Offer in accordance with its terms.  The Offer shall be made by
means of an Offer to Purchase having only the conditions set forth in the
Appendix hereto, which may be asserted by the Purchaser in its sole discretion.
The Purchaser may at any time, at its sole discretion, increase the price per
Share payable in the Offer.

<PAGE>

     1.2  COMPANY ACTION.

          (a)  The Company hereby approves of and consents to the Offer and
represents that the Board of Directors of the Company, at a meeting duly called
and held, duly and unanimously adopted resolutions approving this Merger
Agreement, the Offer and the Merger, determining that the terms of the Offer and
the Merger are fair to, and in the best interests of, the Company's stockholders
and recommending that the Company's stockholders approve and adopt this Merger
Agreement, if a vote is required by applicable law, and that the Company's
stockholders accept the Offer and tender their Shares pursuant to the Offer. The
Company represents that its Board of Directors has received the opinion of
Dillon, Read & Co. Inc. (and such opinion has not been withdrawn) that the
proposed consideration to be received by the holders of Shares pursuant to the
Offer and the Merger is fair to such holders from a financial point of view, and
a complete and correct signed copy of such opinion has been delivered by the
Company to the Purchaser.

          (b)  Concurrently with the commencement of the Offer, the Company
shall file with the Securities and Exchange Commission (the "SEC") and mail to
the holders of Shares a Solicitation/ Recommendation Statement on Schedule 14D-9
(the "Schedule 14D-9"), which shall reflect the recommendations described in the
preceding paragraph (a).  The Company agrees that the Schedule 14D-9, including
all amendments and supplements thereto, shall, (i) in all material respects,
comply with the requirements of the Exchange Act and the rules and regulations
thereunder and other applicable laws; (ii) include all information required by
Rule 14f-1 of the Exchange Act; and (iii) not 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 were made, not misleading; PROVIDED, HOWEVER,
that the foregoing representation shall not apply with respect to the accuracy
of information furnished in writing by the Purchaser specifically for inclusion
in the Schedule 14D-9 or taken from reports filed by the Purchaser under the
Exchange Act.  None of the information furnished in writing or confirmed in
writing by the Company for inclusion in the Offer Documents (as defined in
Section 3.4), will 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 were
made, not misleading.  The Purchaser and Merger Sub and their counsel shall be
given an opportunity to review the Schedule 14D-9 prior to it being filed with
the SEC.  The Company agrees promptly to correct any information provided by it
for use in the Offer Documents if and to the extent that it shall have become
false or misleading in any material respect.

                                       -2-

<PAGE>

          (c)  The Company will promptly furnish the Purchaser with mailing
labels containing the names and addresses of the record holders of Shares and
lists of securities positions of Shares held in stock depositories, each as of a
recent date, and shall furnish the Purchaser with such additional information
(including updated lists of shareholders, mailing labels and lists of securities
positions) and assistance as the Purchaser may reasonably request to communicate
the Offer to the shareholders of the Company.

     2.   THE MERGER

     2.1  THE MERGER.  At the Effective Time (as defined in Section 2.3 hereof),
in accordance with this Merger Agreement and the New Jersey Business Corporation
Act (the "New Jersey Law"), Merger Sub shall be merged with and into the Company
(the "Merger"), the separate existence of Merger Sub (except as may be continued
by operation of law) shall cease, and the Company shall continue as the
surviving corporation.  The Company hereinafter sometimes is referred to as the
"Surviving Corporation."

     2.2  EFFECT OF THE MERGER.  The Merger shall have the effects set forth in
Section 14A:10-6 of the New Jersey Law.

     2.3  CONSUMMATION OF THE MERGER.  As soon as is practicable after the
satisfaction or waiver of the conditions hereinafter set forth, the parties
hereto will cause the Merger to be consummated by filing a Certificate of Merger
with the Secretary of State of the State of New Jersey, in such form as required
by, and executed in accordance with, the relevant provisions of applicable law.
The time of the filing of the Certificate of Merger with the Secretary of State
of the State of New Jersey is referred to herein as the "Effective Time."

     2.4  CERTIFICATE OF INCORPORATION; BY-LAWS.  The Certificate of
Incorporation and By-Laws of the Company, as in effect immediately prior to the
Effective Time, shall be the Certificate of Incorporation and By-Laws of the
Surviving Corporation, and thereafter shall continue to be its Certificate of
Incorporation and By-Laws until amended as provided therein and under New Jersey
Law.

     2.5  DIRECTORS AND OFFICERS OF SURVIVING CORPORATION.

          (a)  The directors of Merger Sub shall be the initial directors of the
Surviving Corporation and shall hold office from the Effective Time until their
respective successors are duly elected or appointed and qualify in the manner
provided in the Certificate of Incorporation and By-Laws of the Surviving
Corporation, or as otherwise provided by law.

                                       -3-

<PAGE>

          (b)  The officers of the Company at the Effective Time shall be the
initial officers of the Surviving Corporation and shall hold office from the
Effective Time until their respective successors are duly elected or appointed
and qualify in the manner provided in the Certificate of Incorporation and
By-Laws of the Surviving Corporation, or as otherwise provided by law.

     2.6  CONVERSION OF SECURITIES.  At the Effective Time, by virtue of the
Merger and without any action on the part of Merger Sub, the Company or the
holder of any of the securities of the Company or Merger Sub:

          (a)  Each Share issued and outstanding immediately prior to the
Effective Time (other than Shares to be cancelled pursuant to Section 2.6(b)
hereof), shall be cancelled and extinguished and be converted into and represent
the right to receive $7.85 in cash, without interest, or such higher price per
Share as may have been paid pursuant to the Offer (the "Merger Consideration").
All such Shares, by virtue of the Merger and without any action on the part of
the holders thereof, shall no longer be outstanding and shall be cancelled and
retired and shall cease to exist, and each holder of a certificate representing
any such Shares shall thereafter cease to have any rights with respect to such
Shares, except the right to receive the Merger Consideration for such Shares
upon the surrender of such certificate in accordance with Section 2.7.

          (b)  Each Share issued and outstanding immediately prior to the
Effective Time and held in the treasury of the Company or owned by the Purchaser
or any direct or indirect subsidiary of the Purchaser (including the Merger Sub)
shall be cancelled and retired and no payment shall be made with respect
thereto.

          (c)  Each share of Common Stock, par value $1.00 per share, of Merger
Sub issued and outstanding immediately prior to the Effective Time shall be
converted into and become one validly issued, fully paid and nonassessable share
of Common Stock, no par value, of the Surviving Corporation.

     2.7  PAYMENT OF CASH FOR SHARES.  Each holder of a certificate or
certificates representing Shares cancelled upon the Merger pursuant to Section
2.6(a) hereof may thereafter surrender such certificate to a disbursing agent to
be designated by the Purchaser and reasonably satisfactory to the Company (the
"Disbursing Agent"), as agent for such holders of Shares, to effect the
surrender of such certificates on their behalf for a period ending six months
after the Effective Time.  The Purchaser agrees that promptly after the
Effective Time it will distribute to such holders a form of letter of
transmittal and instructions for use in effecting the surrender of the
certificates which,

                                       -4-

<PAGE>

immediately prior to the Effective Time, represented Shares in exchange for
payment therefor.  Each such holder shall be entitled upon surrender of one or
more certificates formerly representing Shares, together with a letter of
transmittal, duly executed and completed in accordance with the instructions
thereto, to receive in exchange therefor a check representing the amount to
which such holder is entitled in respect of the cancelled Shares represented by
such certificates after giving effect to any required tax withholding.  Until so
surrendered and exchanged, each such certificate shall, after the Effective
Time, be deemed to represent only the right to receive such amount.  If payment
is to be made to a person other than the person in whose name a surrendered
certificate is registered, it shall be a condition to such payment that the
certificate so surrendered shall be endorsed or shall be otherwise in proper
form for transfer, with the registered owner's signature guaranteed by a firm
which is a member of a registered national securities exchange or of the
National Association of Securities Dealers, Inc. or by a commercial bank or
trust company having an office or correspondent in the United States, and that
the person requesting such payment shall have paid any transfer and other taxes
required by reason of such payment in a name other than that of the registered
holder of the certificate surrendered or shall have established to the
satisfaction of the Purchaser or the Disbursing Agent that such tax either has
been paid or is not payable.  If any cash is deposited with the Disbursing Agent
for purposes of payment in exchange for such Shares and remains unclaimed
following the expiration of six months after the Effective Time, such cash shall
be delivered to the Purchaser by the Disbursing Agent, and thereafter the
Disbursing Agent shall not be liable to any persons claiming any amount of such
cash and the surrender and exchange shall be effected directly with the
Purchaser.  No interest shall accrue or be payable with respect to any amounts
which any holder shall be entitled to receive.  The Purchaser or the Disbursing
Agent shall be authorized to pay the cash attributable to any certificate
theretofore issued which has been lost or destroyed, but only upon receipt of
satisfactory evidence of ownership of the Shares represented thereby and of
appropriate indemnification.  From and after the Effective Time, the holders of
certificates evidencing ownership of Shares outstanding immediately prior to the
Merger shall cease to have any rights with respect to such Shares except as
otherwise provided herein or by law.

     2.8  TAKING OF NECESSARY ACTION; FURTHER ACTION.  If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes of this Merger Agreement and to vest the Surviving Corporation with
full rights, title and possession to all assets, properties, rights, privileges,
immunities and franchises of either the Company or Merger Sub, the officers and
directors of each such corporation

                                       -5-

<PAGE>

are fully authorized in the name of such corporation or otherwise to take, and
shall take, all such lawful and necessary action.

     2.9   CLOSING.  The closing of the Merger shall take place at the offices
of W. R. Grace & Co., One Town Center Road, Sixth Floor, Boca Raton, Florida
33486 at 9:00 a.m., local time on the second business day after the satisfaction
or waiver of the conditions set forth in Article 7.

     2.10 TRANSFER OF SHARES AFTER EFFECTIVE DATE.  No transfers of Shares shall
be made on the stock transfer books of the Surviving Corporation at or after the
Effective Time.

binding obligation of each such company.  Neither the Purchaser nor Merger Sub
is subject to or obligated under any provision of (i) its respective Certificate
of Incorporation or By-Laws, (ii) any contract, (iii) any license, franchise or
permit or (iv) any law, regulation, order, judgment or decree, which would be

                                       -6-

<PAGE>

execution and performance of this Merger Agreement, except (as to (ii), (iii) or

consent or approval of any party other than (i) approval by the Purchaser as the
sole shareholder of Merger Sub, (ii) applicable requirements, if any, of the
Exchange Act, state "blue sky" or takeover laws and the Hart-Scott-Rodino

credit available for use in connection with the acquisition of the Company in an

information furnished in writing by the Company specifically for inclusion in

the Exchange Act, which accuracy shall be the sole responsibility of the
Company.

     4.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company represents and warrants to each of the Purchaser and Merger Sub
as follows:

     4.1  ORGANIZATION AND QUALIFICATION.  The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
New Jersey and has the requisite corporate power to carry on its business as it
is now being conducted.  The Company is duly qualified as a foreign

                                       -7-

<PAGE>

corporation to do business, and is in good standing, in each jurisdiction where
the character of its properties owned or leased or the nature of its activities
makes such qualification necessary, except where the failure to be so qualified
would not have a "Material Adverse Effect".  As used in this Merger Agreement,
the term "Material Adverse Effect" shall mean a material adverse effect in the
business, financial condition, results of operations, properties, assets or
liabilities or, to the Company's knowledge, prospects, of the Company and its
Subsidiaries (as defined below) and shall be measured by reference to the
Company and its Subsidiaries, taken as a whole, and the size of the transactions
contemplated by the Offer and the Merger, taken together, and shall not be
determined solely by reference to accounting concepts of materiality unless the
matter involves accounting matters or the context of this Merger Agreement
otherwise requires.

     4.2  CERTIFICATE OF INCORPORATION AND BY-LAWS.  The Certificate of
Incorporation and By-Laws in the form attached hereto as Exhibits 1 and 2,
respectively, are the Certificate of Incorporation and By-Laws of the Company as
in effect on the date of this Merger Agreement.

     4.3  SUBSIDIARIES.  Each subsidiary of the Company (each a "Subsidiary" and
collectively the "Subsidiaries") is a corporation duly organized, validly
existing and in good standing under the laws of its jurisdiction of
incorporation and has the requisite corporate power to carry on its business as
it is now being conducted.  Each Subsidiary is duly qualified as a foreign
corporation to do business, and is in good standing, in each jurisdiction where
the character of its properties owned or leased or the nature of its activities
makes such qualification necessary, except where the failure to be so qualified
would not have a Material Adverse Effect.  All of the outstanding shares of
capital stock of each of the Subsidiaries are validly issued, fully paid and
nonassessable and are owned by the Company or by a wholly owned Subsidiary of
the Company, free and clear of all liens, claims, charges or encumbrances, and
there are no proxies outstanding with respect to such shares.  The Company has
delivered to the Purchaser a true and complete list of the ownership interests
of the Company in the Subsidiaries and in any other corporation, partnership,
joint venture or other business association or entity.

     4.4  CAPITALIZATION. The authorized capital stock of the Company consists
of 50,000,000 Shares and 10,000,000 shares of preferred stock, no par value (the
"Preferred Stock").  As of the date hereof, (i) 11,546,232 Shares were
outstanding, all of which were validly issued, fully paid and nonassessable,
(ii) no Shares were held in the treasury of the Company or any of its
Subsidiaries, (iii) 1,108,707 Shares were reserved for issuance

                                       -8-

<PAGE>

pursuant to the Company's 1989 Stock Option Plan and the 1989 Non-Employee
Director Stock Option Plan (the "Stock Option Plans"), copies of which have
heretofore been furnished to the Purchaser, and 200,000 Shares were reserved for
issuance pursuant to the Company's Stock Purchase Plan (the "Stock Purchase
Plan"), (iv) options to purchase 881,470 Shares (the "Stock Options") were
outstanding pursuant to the Stock Option Plans, (v) no shares of the Preferred
Stock were outstanding in the aggregate, and (vi) ten notes with $35,712.50 in
principal amounts outstanding in the aggregate and convertible in the aggregate
into 1,536 Shares was outstanding (the "Convertible Notes").  The Company has
previously provided to the Purchaser a true and complete listing of all Stock
Options, the number of Stock Options so held and the exercise prices of such
Stock Options.  All Stock Options are, or will become as a result of the
transactions contemplated by this Agreement, immediately exercisable.  A maximum
of 10,000 Shares will be issued during the calendar quarter ending March 31,
1994, under the Company's Stock Purchase Plan.  The Company has taken such
actions (including obtaining any required consents) as may be necessary such
that at the Effective Time each Stock Option outstanding pursuant to the Stock
Option Plans or otherwise, whether or not then vested or exercisable or subject
to stockholder approval, shall by operation of the Stock Option Plans be
cancelled and will entitle the holder thereof, upon surrender thereof, to
receive an amount in cash equal to the excess, if any, of the Merger
Consideration over the exercise price per Share of such Stock Option multiplied
by the number of Shares previously subject to such Stock Option.  Except as set
forth above or pursuant to the Stock Purchase Plan, there are not now, and at
the Effective Time there will not be, any shares of capital stock or other
equity securities of the Company issued or outstanding or any options, warrants
or other rights, agreements, arrangements or commitments obligating the Company
or any of its Subsidiaries to issue or sell any shares of capital stock of the
Company or of any Subsidiary.  There are no outstanding contracts of the Company
or any Subsidiary to repurchase, redeem or otherwise acquire any capital stock
or other equity securities of the Company or any Subsidiary.

     4.5  AUTHORITY RELATIVE TO THIS MERGER AGREEMENT.  The Company has the
requisite corporate power and authority to enter into this Merger Agreement and
to perform its obligations hereunder.  The execution and delivery of this Merger
Agreement by the Company and the consummation by the Company of the transactions
contemplated hereby have been duly authorized by the Board of Directors of the
Company and no other corporate proceedings on the part of the Company are
necessary to authorize this Merger Agreement and the transactions contemplated
hereby, except for any required approval of the Merger by the Company's
shareholders as set forth in Section 6.2 of this Merger

                                       -9-

<PAGE>

Agreement.  This Merger Agreement has been duly executed and delivered by the
Company and constitutes a valid and binding obligation of the Company.  Except
as disclosed on SCHEDULE 4.5 to this Merger Agreement, neither the Company nor
any Subsidiary is subject to or obligated under any provision of (i) its
respective Certificate or Articles of Incorporation or By-Laws, (ii) any
contract (excluding all contracts which are terminable upon 90 days or less
notice without premium or penalty or contracts involving not more than $50,000
per fiscal year in payments expected to be paid by the Company or any
Subsidiary), (iii) any license, franchise or permit, or (iv) any law,
regulation, order, judgment or decree, which would be breached, violated or
defaulted (with or without due notice or lapse of time or both) or in respect of
which a right of termination or acceleration or a loss of a material benefit or
any encumbrance on any of its assets would be created or suffered by its
execution and performance of this Merger Agreement, except (as to clauses (ii),
(iii) or (iv) above) where such breach, violation, right of termination or
acceleration, or encumbrance, individually or in the aggregate, would not have a
Material Adverse Effect.  Except as disclosed on SCHEDULE 4.5 to this Merger
Agreement, the consummation of the Offer and the Merger by the Company will not
require the consent or approval of or registration or filing with any Federal,
state or local government or any court, administrative or regulatory agency or
commission or other governmental authority or agency, domestic or foreign, other
than (i) approval of the holders of Shares if required by applicable law or by
the Company's Certificate of Incorporation or By-Laws, (ii) applicable
requirements, if any, of the Exchange Act, state "blue sky" or takeover laws and
the HSR Act, (iii) filing and recordation of appropriate merger documents as
required by the New Jersey Law and (iv) where failure to obtain such consents or
approvals or to make such registration or filing would not have individually or
in the aggregate a Material Adverse Effect on or prevent or materially delay the
Company from performing its obligations under this Merger Agreement.  The Board
of Directors of the Company has approved the Offer, the Merger and this Merger
Agreement and such approval is sufficient to render inapplicable to the Offer,
the Merger and this Merger Agreement and the transactions contemplated by this
Merger Agreement, the provisions of the New Jersey Corporation Takeover Bid and
Disclosure Law (Sections 49:5-1 through 49:5-19 of the New Jersey Law) and the
New Jersey Shareholder Protection Act (Sections 14A:10A-1 through 14A:10A-6 of
the New Jersey Law).  To the best of the Company's knowledge, no other state
takeover statute or similar statute or regulation applies or purports to apply
to the Offer, the Merger, this Merger Agreement or any of the transactions
contemplated hereby.

applicable to such SEC Documents, and none of the SEC Documents contained any
untrue statement of a material fact or omitted to state a material fact required

in the ordinary course of business consistent with past practice, since
December 31, 1993, neither the Company nor any Subsidiary has any material
liabilities or obligations of any nature (whether accrued, absolute, contingent
or otherwise) required by generally accepted accounting principles to be set
forth on the

                                      -11-

<PAGE>

consolidated balance sheet of the Company and its consolidated Subsidiaries
included in the Unaudited 1993 Financial Statements or in the notes thereto.

     4.7  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since September 30, 1993,
except as previously disclosed in writing to the Purchaser, neither the Company
nor any Subsidiary has:  (a) suffered any Material Adverse Effect or any event,
change or condition, known as of the date hereof, likely to cause or have any
such Material Adverse Effect, other than as a result of changes in conditions,
including economic or political developments, applicable to the business of
health care generally or the business of home infusion therapy generally not
having a disproportionate effect on the Company's business relative to the
effect of any such change on other entities in the business of home infusion
therapy; or (b) conducted its business and operations other than in the ordinary
course of business and consistent with past practices except, subsequent to the
date hereof, as permitted by Section 5.1 hereof.

     4.8  LITIGATION AND LIABILITIES.  Except as disclosed in the SEC Documents
and except as previously disclosed in writing to the Purchaser, there are no
actions, suits or proceedings pending or, to the knowledge of the management of
the Company, threatened against the Company or any of the Subsidiaries that are
reasonably likely, in the aggregate, to have a Material Adverse Effect or that
would be required to be disclosed in an Annual Report or Form 10-K of the
Company.

     4.9  EMPLOYEE BENEFITS.  (a)  True and complete copies of all documents
comprising Benefit Plans have been provided to the Purchaser.  For purposes of
this Merger Agreement, the term "Benefit Plan" includes any plan, contract or
arrangement (regardless of whether funded or unfunded, or foreign or domestic)
which is sponsored by the Company or any of the Subsidiaries, or to which the
Company or any of the Subsidiaries makes contributions or which covers any
Employee of the Company or any Subsidiary in his or her capacity as an Employee
or to which the Company or any Subsidiary has any obligation with respect to any
current or former employee, and which is (i) an "Employee Benefit Plan" within
the meaning of Section 3(3) of the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), (ii) a severance contract with (an) employee(s) or
any severance plan applicable to employees, or (iii) a stock option plan or any
other plan of deferred compensation.

          (b)  All Benefit Plans are valid and binding and in full force and
effect and there are no defaults thereunder.  Each Benefit Plan complies
currently, and has complied in the past, in all material respects and in form
and operation, with all applicable provisions of ERISA, the Internal Revenue
Code of

                                      -12-

<PAGE>

1986, as amended (the "Code"), and other applicable law.  Except as disclosed on
SCHEDULE 4.9 hereto, the Company does not sponsor any "employee pension benefit
plan" within the meaning of Section 3(2) of ERISA ("Pension Plan") which is
intended to be qualified under Section 401(a) of the Code or any retiree
health and life benefits under any Benefit Plan (excluding (i) continuation
coverage required under the Consolidated Omnibus Budget Reconciliation Act of
1985 and (ii) to the extent not material, any written arrangements for post-
termination of employment medical or life coverage between the Company and any
individual).  There is no pending or, to the best knowledge of the Company,
threatened litigation relating to the Benefit Plans, except for pending or
threatened litigation that is not, individually or in the aggregate, reasonably
likely to have a Material Adverse Effect.  Neither the Company nor any of the
Subsidiaries has engaged in, or failed to engage in, a transaction with respect
to any Benefit Plan that is reasonably likely to subject the Company or any of
the Subsidiaries to a tax or penalty imposed by either Section 4975 or 4980B of
the Code or Section 502(i), 502(c), 502(l) and 601 through 608 of ERISA in an
amount which would have a Material Adverse Effect.

          (c)  No Benefit Plan subject to Title IV of ERISA (including any
"multiemployer plan" as defined in ERISA) has been sponsored or contributed to
by the Company or any Subsidiary during the six year period immediately
preceding the date of this Merger Agreement.

          (d)  All contributions required to be made, and claims to be paid,
under the terms of any Benefit Plan have been timely made or reserves therefor
on the balance sheet of the Company have been established, which reserves are
adequate in all material respects.

     4.10  TAXES.  (a)  Each of the Company and the Subsidiaries has timely
filed (subject to extensions), all Tax Returns (as hereinafter defined) required
to be filed by it except for state or local Tax Returns in which the failure to
file would not be reasonably expected to, in the aggregate, have a Material
Adverse Effect, and has duly paid or caused to be paid on its behalf or made or
caused to be made adequate provision for the payment of all Taxes (as
hereinafter defined) shown to be due on such returns.  The information shown on
all Tax Returns of the Company and the Subsidiaries is true and complete, except
where failure to be so true or complete would not have a Material Adverse
Effect.  The accruals made for Taxes on the Unaudited 1993 Financial Statements
and, since December 31, 1993, on the Company's and the Subsidiaries' books and
records are sufficient for the payment of all unpaid Taxes payable by the
Company or the Subsidiaries attributable to all periods ending on or before the
date hereof.  Neither the Company nor the Subsidiaries have

                                      -13-

<PAGE>

incurred, nor are there accruable, any liabilities (whether absolute, contingent
or otherwise, and whether due or to become due) on account of Taxes other than
on account of the kinds of taxes in respect of which accruals have been made on
the Unaudited 1993 Financial Statements and at rates not in excess of the rates
reflected in such accruals unless such higher rate is attributable to a change
in law.  The Company and each of its Subsidiaries has delivered to Purchaser (A)
complete and correct copies of all income Tax Returns and all gross receipts and
franchise Tax returns to the extent such gross receipts and franchise Taxes are
based upon the income of the Company or any of its Subsidiaries with respect to
tax years for which the statute of limitations has not run, (B) complete and
accurate copies of all ruling requests, private letter rulings, deficiency
notices or notices of proposed deficiencies, closing agreements, settlement
agreements, revenue agent reports, information document requests and responses
thereto, protests, petitions and any other similar documents submitted on behalf
of the Company and/or its Subsidiaries and (C) a complete and correct list of
all states, localities and foreign jurisdictions with which the Company and/or
its Subsidiaries has a business establishment.  Except as previously disclosed
in writing to the Purchaser, (A) no written claims for U.S. Federal income Taxes
have been or, to the knowledge of the Company and its Subsidiaries, are likely
to be asserted against the Company or any of the Subsidiaries, or any
affiliated, consolidated or unitary group of which the Company and/or the
Subsidiaries is or was a member, and no deficiency for any U.S. Federal income
Taxes has been proposed, asserted or assessed which has not been resolved or
paid in full with respect to the Company, the Subsidiaries or any affiliated,
consolidated or unitary group of which the Company and/or the Subsidiaries is
or was a member, (B) no written claims for Taxes other than U.S. Federal income
taxes have been or, to the knowledge of the Company and its Subsidiaries, are
likely to be asserted against the Company or any of the Subsidiaries or any
affiliated, consolidated or unitary group of which the Company and/or the
Subsidiaries is or was a member, and no deficiency for any Taxes other than
U.S. Federal income Taxes has been proposed, asserted or assessed which has not
been resolved or paid in full, which is reasonably likely to have a Material
Adverse Effect with respect to the Company, the Subsidiaries or any affiliated,
consolidated or unitary group of which the Company and/or the Subsidiaries is
or was a member, (C) no Tax Return or taxable period of the Company or any of
the Subsidiaries or any affiliated, consolidated or unitary group of which the
Company and/or the Subsidiaries is or was a member, is under examination and

any pending audit (D) there are no outstanding agreements or waivers extending
the statutory period of limitation applicable to any Tax Return or Taxes for
any period of the Company or the Subsidiaries, or any affiliated,

                                      -14-

consolidated or unitary group of which the Company and/or the Subsidiaries is
or was a member, and the Company and the Subsidiaries have not entered into any
closing agreements or settlement agreement with any tax authority, (E) the
Company and the Subsidiaries collectively have no obligation or liability to
pay Taxes of or attributable to any other person or entity or any affiliated,
consolidated or unitary group of which the Company and/or the Subsidiaries is
or was a member, other than those obligations or liabilities that would not
individually or in the aggregate have a Material Adverse Effect, (F) no issue
or claim has been asserted in writing or, to the Company's knowledge, is
threatened or pending by any taxing authority for Taxes for any prior period,
the adverse determination of which could result in deficiencies which could,
individually or in the aggregate, have a Material Adverse Effect, (G) there are
no tax liens other than statutory liens for Taxes not yet due, (H) neither the
Company nor any Subsidiary is a party to any agreement or contract which would
result in payment of any "excess parachute payment" within the meaning of
Section 28OG of the Code or which would result in the disallowance of a
deduction under Section 162(m) of the Code, (I) neither the Company nor any of
the Subsidiaries has been a member of any affiliated, consolidated, combined,
unitary or aggregate groups for purposes of filing Tax Returns or paying Taxes
at any time, (J) neither the Company nor any of the Subsidiaries will be
required to make any adjustment under Section 481 of the Code (or any analogous

Date as a result of actions taken prior to the Closing, (K) neither the Company
nor any of the Subsidiaries will be required to include in a taxable period on

economically accrued in a taxable period ending on or before the Closing Date,
including, without limitation, as a result of the installment method of
accounting, the completed contract method of accounting or the cash method of

from each payment made to their employees the amount of all taxes (including,
but not limited to, federal income taxes, Federal Insurance Contribution Act
taxes and foreign, state and local income, payroll and wage taxes) required to
be withheld or collected therefrom and has paid the same to the proper tax
receiving officers.

          (b)  The Company and the Subsidiaries have not filed any consent
pursuant to Section 341(f) of the Code or agreed to have Section 341(f)(2) of
the Code apply to any disposition of a subsection (f) asset owned by the Company
or any of the Subsidiaries.

For purposes of this Agreement, "Tax Return" shall mean any report, return,

     4.11  INFORMATION SUPPLIED.  Any proxy statement mailed by the Company to
the holders of Shares after the date hereof and all amendments and supplements
thereto will comply as to form in all material respects with the applicable
requirements of the Exchange Act and the rules and regulations thereunder and
will not, at the time of (a) the first mailing thereof or (b) the meeting called
pursuant to Section 6.2 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
were made, not misleading, except that no representation is made by the Company
with respect to (i) information supplied by the Purchaser or Merger Sub
expressly for inclusion in such proxy statement or (ii) any proxy statement
prepared and mailed after Purchaser has obtained a majority of seats on the
Company's Board of Directors.

     4.12  LICENSES AND PERMITS.  (a)  The Company and the Subsidiaries have
obtained all licenses and permits necessary to conduct its business and to own
and operate its assets and such licenses and permits are valid and in full force
and effect except where the failure to obtain such licenses and permits would
not individually or in the aggregate have a Material Adverse Effect.  The
Company and the Subsidiaries have all supplier numbers or authorizations

and covered by Part A of the Medicare Program as a Medicare certified home
health agency (collectively, "Medicare Authorizations").  No defaults or
violations exist or have been recorded in respect of any license or permit of
the Company and the Subsidiaries other than defaults or violations which would
not reasonably be expected individually or in the aggregate to have a Material
Adverse Effect.  No proceeding is pending or, to the best knowledge of the
Company, threatened looking toward the revocation, limitation or non-renewal of
any such license, permit or Medicare Authorizations, except for pending or
threatened proceedings that would not, in the aggregate, reasonably be expected
to have a Material Adverse Effect.

          (b)  The Company has delivered or made available for inspection to the
Purchaser a true and complete list of each material license and permit, and each
material pending application for any license or permit, relating to the Company

without challenge of any kind, and each statement, application and other
document submitted or filed by the Company or any Subsidiary to or with any

connection with the transactions contemplated hereby is true and complete, and
except as disclosed on SCHEDULE 4.5, none of the rights of the Company or any
Subsidiary under any license, permit or Medicare Authorization will be impaired
by the consummation of the transactions contemplated hereby, except, as to the
foregoing matters, for such challenges, incompletenesses or inaccuracies,
nondisclosures or impairments which would not, individually or taken in the
aggregate, have a Material Adverse Effect.

          (c)  Since December 31, 1992, the Company has not received any written
notice from and has not been made a party to any proceeding brought by any
governmental authority alleging that (a) the Company is, or may be in violation

governmental regulation or order, (c) the Company has failed to obtain any

this Section shall be deemed to be a breach of this Section 4.12.

                                      -17-

     4.13  COMPLIANCE WITH LAWS.  The Company and the Subsidiaries have complied
in a timely manner with all laws and governmental regulations and orders
relating to any of the property owned, leased or used by them, or applicable to
their business, including, but not limited to, the labor, equal employment
opportunity, occupational safety and health, environmental, hazardous or medical
waste disposal and antitrust laws, except where the failure to so comply would
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.  Nothing which has been disclosed in writing to the Purchaser in
connection with its investigation of the matters covered by this Section 4.13
and identified as specifically related to this Section shall be deemed to be a
breach of this Section 4.13.  Since December 31, 1992, neither the Company nor
any of its Subsidiaries has been charged or, to the Company's knowledge,
investigated or received any inquiries in or relating to any violations of any
state or federal statute or regulation involving fraudulent or abusive practices
relating to its reimbursement from third party payors or its participation in
state or federally sponsored reimbursement programs, including but not limited
to fraudulent billing practices.  No significant amount of funds are now or, to
the Company's knowledge, are expected to be withheld by any Medicare carrier,
state agency or third party payor, other than pursuant to practices or policies
of applicability to multiple parties within the industry.

     4.14  INSURANCE.  As of the date hereof, the Company and each of its
Subsidiaries are covered under insurance policies and programs of Seller which
provide coverage to the Company by insurers, reasonably believed by the Company
to be of recognized financial responsibility and solvency, 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 the Company or any of its Subsidiaries or their respective businesses,
assets, employees, officers and directors of which Seller or the Company have
copies have previously been made available for inspection by the Purchaser and
are in full force and effect.  Except as otherwise disclosed pursuant to Section
4.8, as of the date hereof, there are no material claims by the Company or any
Subsidiary under any such policy or instrument as to which any insurance company
is denying liability or defending under a reservation of rights clause.  All
necessary notifications of claims have been made to insurance carriers other
than those where the failure to so notify will not have a Material Adverse
Effect.

     4.15  CONTRACTS.  All material contracts, agreements, commitments and other
documents to which the Company or any Subsidiary is a party or by which the
Company, any Subsidiary, or any of their assets is in any way affected or bound,
including all amendments and supplements thereto and modifications thereof

                                      -18-

<PAGE>

(collectively, the "Material Contracts"), are legally valid and binding and in
full force and effect, except where failure to be legally valid and binding and
in full force and effect would not have a Material Adverse Effect or results
from changes in applicable laws or legal interpretations after the date hereof,
and there are no defaults thereunder, except (i) those defaults that would not,
individually or in the aggregate, be reasonably expected to have a Material
Adverse Effect and (ii) those defaults that based on the general experience of
the Company's industry do not create a material risk of termination.  The
Company has previously made available for inspection by the Purchaser all
written Material Contracts.  The Company has previously provided the Purchaser
with copies of any agreement with any executive officer or other key employee of
the Company or any Subsidiary (A) the benefits of which are contingent, or the
terms of which are materially altered, upon the occurrence of a transaction
involving the Company or any Subsidiary of the nature of any of the transactions
contemplated by this Merger Agreement, (B) providing any term of employment or
compensation guarantee extending for a period longer than three years or
(C) providing severance benefits or other benefits after the termination of
employment of such executive officer or key employee not comparable to benefits
available to employees generally.

     4.16  EARNOUT PAYMENTS.  SCHEDULE 4.16 sets forth a list of contingent
payment obligations presently in effect which the Company has previously paid
and the Company's best estimate based upon current operating performance of its
projected contingent payments for the life of such contingent payment
obligations under agreements pursuant to which the Company has acquired other
businesses.

     4.17  TITLE TO PROPERTIES.  Neither the Company nor the Subsidiaries own
any real property.  Except as previously disclosed in a writing delivered to the
Purchaser, the Company and the Subsidiaries have good title to all personal and
intangible property reflected in the Company's December 31, 1993 balance sheet
previously delivered to Purchaser (except as disposed of since such date in the
ordinary course of business), free and clear of all security interests, liens,
encumbrances, restrictions and other burdens ("Liens") other than Liens under
the Credit Agreement (as defined in Section 6.5) and such other liens which in
the aggregate do not and will not materially interfere with its ability to
conduct its business as presently conducted.

     4.18  LABOR MATTERS.  There are no collective bargaining or other labor
union agreements to which the Company or any of its Subsidiaries is a party or
by which any of them is bound.  To the best knowledge of the Company, since
September 30, 1993, neither

                                      -19-

<PAGE>

the Company nor any of its Subsidiaries has encountered any labor union
organizing activity, or had any actual or threatened employee strikes, work
stoppages, slowdowns or lockouts.

          (d)  the Company shall use reasonable business efforts to preserve

substantial portion of the assets of, or by any other manner, any business or

1994.

     6.4  EXPENSES.  (a)  Except as provided below, all fees and expenses
incurred in connection with the Offer, the Merger, this Merger Agreement and the

to Section 8.1(f)(ii) of this Merger Agreement.  For purposes of this paragraph,

(the "Credit Agreement"), between the Company, Continental Bank, N.A. and LTCB
Trust Company at the Effective Time or such earlier time as may be required by
the Credit Agreement but not earlier than such time as Purchaser acquires Shares
pursuant to the Offer.  Prior to the Effective Time, the Company shall pay in
full the Convertible Note.

     6.6  ADDITIONAL AGREEMENTS.  Subject to the terms and conditions herein
provided, each of the parties hereto agrees to use all reasonable efforts to
take, or cause to be taken, all action and to do, or cause to be done, all
things necessary, proper or advisable to consummate and make effective as
promptly as practicable the transactions contemplated by the Offer and this
Merger Agreement, including (i) filing the Certificate of Merger referred to in
Section 2.3, (ii) using reasonable efforts to remove any legal impediment to the
consummation or effectiveness of such transactions and (iii) using reasonable
efforts to obtain all necessary waivers, consents and approvals and to effect
all necessary registrations and filings, including, but not limited to, filings
under the HSR Act and submissions of information requested by governmental
authorities.

     6.7  NO SOLICITATION.  (a)  The Company shall not, nor shall it permit any
of its Subsidiaries or affiliates to, nor shall it authorize or permit any
officer, director or employee of, or any investment banker, attorney or other
advisor or representative of, the Company or any of its Subsidiaries to,
(i) solicit or initiate, or knowingly encourage the submission of, any takeover
proposal, (ii) participate in any discussions or negotiations regarding, or
furnish to any person any information with respect to any takeover proposal
(except for (1) non-confidential information which is furnished in response to

                                      -24-

<PAGE>

inquiries by securities analysts or institutional investors concerning the Offer
or the Merger, or (2) information which the Company is required to furnish
pursuant to Section 14A:5-28 of the New Jersey Business Corporation Act);
PROVIDED, HOWEVER, that prior to the acceptance for payment of Shares pursuant
to the Offer, to the extent required by the fiduciary obligations of the Board
of Directors of the Company, as determined in good faith by the Board of
Directors based on the written advice of outside counsel, the Company may, (A)
in response to an unsolicited request therefor, furnish information with respect
to the Company (pursuant to a customary confidentiality agreement at least as
restrictive as the Company's Confidentiality Agreement with the Purchaser (as
determined by the Company's outside counsel)) to any person who has indicated to
the Company that it is interested in pursuing a qualified takeover proposal and
discuss such information (but not the terms of any possible takeover proposal)
with such person and (B) upon receipt by the Company of a qualified takeover
proposal, following delivery to the Purchaser of the notice required pursuant to
Section 6.7(c), participate in negotiations regarding such qualified takeover
proposal.  Without limiting the foregoing, it is understood that any violation
of the restrictions set forth in the preceding sentence by any officer of the
Company or any of its Subsidiaries or any investment banker, attorney or other
advisor or representative of the Company or any of its Subsidiaries, whether or
not such person is purporting to act on behalf of the Company or any of its
Subsidiaries or otherwise, shall be deemed to be a breach of this Section 6.7(a)
by the Company.  For purposes of this Merger Agreement, "takeover proposal"
means any proposal for a merger or other business combination involving the
Company or any Subsidiary or any proposal or offer to acquire in any manner,
directly or indirectly, a substantial portion of the assets of the Company, an
equity interest in or any voting securities of the Company (other than pursuant
to the Stock Option Plans or the Stock Purchase Plan) and "qualified takeover
proposal" means a proposal to acquire all Shares by merger, tender offer or
otherwise at a purchase price which includes cash consideration in excess of
$7.85 per share, which in the good faith determination of the Board of Directors
is reasonably likely to be fully financed.

          (b)  Neither the Board of Directors of the Company nor any committee
thereof shall (i) withdraw or modify, or propose to withdraw or modify, in a
manner adverse to the Purchaser or Merger Sub, the approval or recommendation by
such Board of Directors or any such committee of the Offer, this Merger
Agreement or the Merger, (ii) approve or recommend, or propose to approve or
recommend, any takeover proposal or (iii) enter into any agreement with respect
to any takeover proposal.  Notwithstanding the foregoing, in the event the Board
of Directors of the Company receives a superior takeover proposal (as defined

                                      -25-

<PAGE>

below), the Board of Directors may (subject to the limitations contained in this
Section) withdraw or modify its approval or recommendation of the Offer, this
Merger Agreement or the Merger, approve or recommend any such superior takeover
proposal, enter into an agreement with respect to any such superior takeover
proposal or terminate this Merger Agreement in each case at any time after 48
hours following the Purchaser's receipt of written notice (a "Notice of Superior
Takeover Proposal") advising the Purchaser that the Board of Directors has
received a superior takeover proposal, specifying the material terms and
conditions of such superior takeover proposal and identifying the person making
such superior takeover proposal.  The Company may take any of the forgoing
actions pursuant to the preceding sentence only if Merger Sub shall not have
accepted for payment the Shares pursuant to the Offer.  In addition, if the
Company proposes to enter into an agreement with respect to any takeover
proposal, terminate the Merger Agreement, approve or recommend a superior
takeover proposal or withdraw or modify its approval or recommendation of the
Offer, this Merger Agreement or the Merger, it shall within two business days of
the taking of any such action pay, or cause to be paid, to the Purchaser the
Termination Fee (in accordance with and as defined in Section 6.4(b)).  Nothing
contained herein shall prohibit the Company from taking and disclosing to its
stockholders a position contemplated by Rule 14e-2(a) following the Purchaser's
receipt of a Notice of Superior Takeover Proposal provided that the Company does
not withdraw or modify its position with respect to the Offer or Merger or
approve or recommend a takeover proposal.  For purposes of this Merger
Agreement, a "superior takeover proposal" means a qualified takeover proposal
having terms which the Board of Directors of the Company determines in its good
faith reasonable judgment (based on advice of a financial advisor of nationally
recognized reputation) to be more favorable to the Company's stockholders than
the Offer and the Merger.

          (c)  In addition to the obligations of the Company set forth in
paragraph (b) of this Section, the Company shall promptly advise the Purchaser
orally and in writing of any request for information or of any takeover
proposal, or any inquiry with respect to any takeover proposal, the material
terms and conditions of such request, takeover proposal or inquiry, and the
identity of the person making any such takeover proposal or inquiry.  The
Company will keep the Purchaser fully informed of the status and details of any
such request, takeover proposal or inquiry.

     6.8  OFFICERS' AND DIRECTORS' INSURANCE; INDEMNIFICATION.  The Purchaser
will cause the Surviving Corporation to (i) either (a) purchase and maintain a
directors' and officers' insurance and indemnification policy substantially
equivalent to the Company's current policy for all current officers and
directors

                                      -26-

<PAGE>

of the Company on the date of this Merger Agreement, for three years after the
Effective Time to cover acts and omissions of directors and officers of the
Company occurring prior to the Effective Time or (b) request Seller to obtain
such coverage and provide reimbursement to Seller for the cost thereof and
(ii) maintain in effect the current provisions of the By-Laws of the Company
(which shall be contained in the By-Laws of Merger Sub and the Surviving
Corporation) relating to the rights to indemnification of officers and directors
with respect to indemnification for acts and omissions occurring prior to the
Effective Time.

     6.9  NOTIFICATION OF CERTAIN MATTERS.  The Company shall give prompt notice
to the Purchaser, and the Purchaser shall give prompt notice to the Company, of
(i) the occurrence, or failure to occur, of any event, which occurrence or
failure would be likely to cause any representation or warranty contained in
this Merger Agreement to be untrue or inaccurate at any time from the date
hereof to the Effective Time, provided that each party's obligation hereunder is
limited to events of which it has knowledge, and (ii) any material failure of
the Company or the Purchaser, as the case may be, or any officer, director,
employee or agent thereof, to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by it hereunder.

     6.10  ACCESS TO INFORMATION.  The Company shall, and shall cause its
Subsidiaries, officers, directors, employees and agents to, afford the officers,
employees and agents of the Purchaser complete access at all reasonable times,
from the date hereof to the Effective Time, to its officers, employees, agents,
properties, books and records, and shall furnish the Purchaser all financial,
operating and other data and information as the Purchaser, through its officers,
employees or agents, may reasonably request.  Subject to applicable law, the
Purchaser shall cause all such information of a non-public nature to be retained
confidentially.  If this Merger Agreement is terminated, Purchaser shall
promptly comply with the provisions of the Confidentiality Agreement previously
entered into by the Company and Dillon, Read & Co. Incorporated, as agent for
the Company and Seller, with respect to the return of confidential information
to the Company by the Purchaser.

     6.11  EMPLOYEE BENEFITS.  For at least two years following the consummation
of the Merger, the Purchaser agrees that the employees of the Company will be
provided with employee benefits which in the aggregate are not less favorable
than those provided by National Medical Care, Inc. to its employees who are
similarly situated.  For purposes of this Section 6.11, the Purchaser shall not
be obligated under this Merger Agreement to continue the employment of any
employee of the Company or to continue the

                                      -27-

<PAGE>

Stock Option Plans or the Stock Purchase Plan maintained by the Company.  All
employees of the Company who continue their employment with the Company or any
subsidiary of the Purchaser after the closing date under the Stock Purchase
Agreement or the purchase of the Seller's shares in the Company under the Offer
(the "Cut-Off Date") shall be given credit for their service with the Company
prior to the Cut-Off Date for purposes of determining eligibility and vesting
(other than with respect to National Medical Care's retirement plan) under
benefit plans sponsored by the Company, the Purchaser or any subsidiary of the
Purchaser applicable to such employees after the Cut-Off Date.

     6.12  ANTITRUST LAWS.  As promptly as practicable, the Company, the
Purchaser and Merger Sub shall make all filings and submissions under the HSR
Act as may be reasonably required to be made in connection with this Merger
Agreement and the transactions contemplated hereby.  Subject to Section 6.10
hereof, the Company will furnish to the Purchaser and Merger Sub, and the
Purchaser and Merger Sub will furnish to the Company, such information and
assistance as the other may reasonably request in connection with the
preparation of any such filings or submissions.  Subject to Section 6.10 hereof
and to the preservation of attorney-client privilege and work-product doctrine,
the Company will provide the Purchaser and Merger Sub, and the Purchaser and
Merger Sub will provide the Company, with copies of all correspondence, filings
or communications (or memoranda setting forth the substance thereof) between
such party or any of its representatives, on the one hand, and any governmental
agency or authority or members of their respective staffs, on the other hand,
with respect to this Merger Agreement and the transactions contemplated hereby;
PROVIDED, HOWEVER, that the Purchaser and Merger Sub shall not be required to
provide the Company with copies of confidential documents or information
included in the Purchaser's filings and submissions under the HSR Act.

     6.13  PUBLIC ANNOUNCEMENTS.  The Purchaser and Merger Sub, on the one hand,
and the Company, on the other hand, agree that they will use reasonable efforts
to consult with the other party prior to issuing any press release or otherwise
making any public statement or responding to any press inquiry with respect to
this Merger Agreement or the transactions contemplated hereby.

     6.14  DIRECTORS.  Subject to Section 14(f) of the Exchange Act and Rule
14f-1 promulgated thereunder, upon the acceptance for payment of, and payment
for, any Shares by Merger Sub pursuant to the Offer or the Stock Purchase
Agreement which, when taken together with the Shares which the Purchaser
beneficially owns (as such term is defined under the Exchange Act) represent at
least a majority of the then outstanding Shares, Merger Sub shall be entitled to
designate the directors on the Board of

                                      -28-

<PAGE>

Directors of the Company, and the Company shall, at such time, promptly increase
the size of the Board of Directors of the Company to the extent necessary to
enable Merger Sub's designees to be elected to, and to constitute a majority of,
the Board of Directors of the Company and shall cause Merger Sub's designees to
be so elected.  The Company agrees to cooperate in permitting the exercise by
Merger Sub of its rights under this Section 6.14, including without limitation
(a) cooperating in satisfying the requirements of Section 14(f) of the Exchange
Act and Rule 14f-1 promulgated thereunder, and (b) amending, prior to the
expiration date of the Offer or the closing under the Stock Purchase Agreement,
any provisions of the By-laws or any agreement by which the Company is bound
that could delay or hinder the ability of Merger Sub or the Purchaser to elect
its designees to a majority of the directorships constituting the Board of
Directors of the Company.  The Company will not take any action to delay or
hinder such election.

     6.15  AUDITED FINANCIAL STATEMENTS.  Prior to March 15, 1994, the Company

     9.4  INTERPRETATION.  When a reference is made in this Merger Agreement to
subsidiaries of the Purchaser or the Company, the word "subsidiaries" or
"Subsidiaries" means any corporation more than fifty percent (50%) of whose
outstanding voting securities are directly or indirectly owned by the Purchaser
or the Company, as the case may be.  The headings contained in this Merger
Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Merger Agreement.

     9.5  NO THIRD PARTY BENEFICIARIES.  There are no third party beneficiaries
of this Merger Agreement and nothing in this Merger Agreement, express or
implied, is intended to or shall confer upon any person other than the parties

remedies, obligations or liabilities.

     9.6  MISCELLANEOUS.  This Merger Agreement (including the documents and
instruments referred to herein) (i) constitutes the entire agreement and
supersedes all other prior agreements and undertakings, both written and oral,
among the parties, or any of them, with respect to the subject matter hereof;
(ii) is not intended to confer upon any other person any rights or remedies
hereunder; (iii) shall not be assigned by operation of law or otherwise,
provided that the Purchaser or Merger Sub may assign its rights and obligations
hereunder to a direct or indirect subsidiary of the Purchaser, but no such
assignment shall relieve the Purchaser or Merger Sub, as the case may be, of its
obligations hereunder; and (iv) shall be governed in all respects, including
validity, interpretation and effect, by the internal laws of the State of New
York without giving effect to the principles of conflict of laws thereof (except
to the extent that New Jersey Law governs any procedural matters relating to the
effectuation of the Merger, in which case New Jersey Law shall apply with
respect to such procedural matters).  This Merger Agreement may be executed in
one or more counterparts which together shall constitute a single agreement.

     9.7  SPECIFIC PERFORMANCE.  The parties hereto agree that irreparable
damage would occur in the event any of the provisions of this Agreement were not

MERGER CORP., a New Jersey corporation and a wholly-owned subsidiary of the
Purchaser (the "Subsidiary"), and HEALTHDYNE, INC., a Georgia corporation (the
"Seller").


                              W I T N E S S E T H:
                              - - - - - - - - - -


     WHEREAS, the Seller owns of record and beneficially 7,800,000 outstanding
shares (the "Shares") of Common Stock, no par value (the "Common Stock"), of
Home Nutritional Services, Inc., a New Jersey corporation (the "Company"); and

     WHEREAS, the Purchaser, the Subsidiary and the Company have on the date
hereof entered into an Agreement and Plan of Merger (the "Merger Agreement")
pursuant to which the Purchaser has agreed to acquire by tender offer (the
"Offer") and merger (the "Merger") all outstanding shares of Common Stock at a
net price of $7.85 per Share; and

     WHEREAS, the Seller desires to sell the Shares to the Purchaser and the
Purchaser desires to purchase the Shares from the Seller at a net cash price of
$7.85 per Share either under the Offer or otherwise; and


     WHEREAS, in formulating the decision to acquire all outstanding shares of
Common Stock of the Company, the Purchaser and the Subsidiary have reviewed and
relied upon the representations and agreements made in this Agreement;


     NOW, THEREFORE, in consideration of the premises and the mutual agreements,
covenants, representations and warranties contained herein and intending to be
legally bound hereby, the parties hereto agree as follows:


1.   SALE OF THE SHARES

     1.1  DESIGNATED SUBSIDIARY.  It is understood and agreed among the parties
that the Purchaser may cause the Subsidiary or any other wholly-owned subsidiary
of Purchaser to carry out certain of the transactions contemplated by this
Agreement

<PAGE>

(including, without limitation, the purchase and receipt of the Shares);
provided, however, that the Purchaser shall remain liable for all of its
obligations and those of the Subsidiary hereunder.


     1.2  SALE AND PURCHASE OF SHARES; TERMINATION.

     (a)  Unless the Shares shall have been purchased previously pursuant to the
Offer as contemplated by subsection (b) of this Section 1.2, subject to Section
6 hereof, Seller shall, not later than the later of (i) five business days
following the Expiration Date (as defined in the Offer to Purchase with respect
to the Offer) or the date of the termination of the Offer in accordance with the
terms of the Offer to Purchase and (ii) the first business day after all
applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements

Purchaser, and the Purchaser shall pay for and acquire from the Seller, the
Shares.  The Purchaser shall notify the Seller of the date set for the purchase
of the Shares (the "Closing Date").  On the Closing Date, the Seller shall
deliver to the Purchaser certificates representing the Shares together with duly
executed stock powers with respect to the Shares in favor of the Purchaser or

the Seller to deliver or the Seller may deliver all, but not part, of the Shares
with related letters of transmittal in accordance with the terms of the Offering
materials used in connection with the Offer, and such delivery shall constitute
a tender by the Seller under the Offer.  If Purchaser directs Seller to deliver
Shares for purchase pursuant to the Offer, Seller shall not be required to
deliver such Shares until two business days prior to the Expiration Date.  Any
Shares tendered at the direction of Purchaser will not be withdrawn unless the
Merger Agreement or this Agreement is terminated in accordance with its terms.
The acceptance for payment of all the Shares pursuant to the Offer shall
constitute the closing of the sale and purchase contemplated by this Agreement.


     (c)  Following the purchase of the Shares hereunder, the Purchaser will use
its reasonable best efforts to effect a merger as soon as practicable after the
Closing Date on terms which will provide to the stockholders of the Company cash
consideration per

                                       -2-

the Seller agrees that, prior to the earlier to occur of the purchase of the
Shares under this Agreement or the termination of this Agreement:

any of the Shares or any interest in the Shares, or grant, or agree to grant, an
option or other right to acquire any of the Shares or any interest in the
Shares; and

     (b)  the Seller will not permit any lien, charge or encumbrance, other than
the existing lien under the Perinatal Credit Agreement, to exist or be placed on
the Shares or subject the Shares to any proxy, voting trust or other agreement,
understanding or arrangement with respect to the Shares.

Agreement, the Purchaser as proxy for the Seller to vote the Shares which the
Seller is entitled to vote, for and in the name, place and stead of the Seller,

and at any adjournments thereof or pursuant to any consent in lieu of a meeting,

3.   COVENANTS OF THE PARTIES PRIOR TO THE SALE OF THE SHARES

     3.1  NEGOTIATIONS.  From the date of this Agreement until the earlier to
occur of the purchase of the Shares hereunder or the termination of this
Agreement or the Merger Agreement, the Seller shall not, directly or indirectly,
solicit, encourage, or initiate or engage in any discussions or negotiations
with, or provide any information to, any corporation, partnership, agent,
financial adviser, person, or other entity or group (other than the Purchaser or
an affiliate or an associate of the Purchaser or an officer, employee or other
authorized representative of the Purchaser or such affiliate or associate)
concerning any merger, sale of substantial assets, sale of substantial amounts
of securities, or similar transactions involving the Company or any sale of the
Shares.

     3.2  PUBLIC DISTRIBUTION.  Neither the Purchaser nor the Subsidiary will
sell or otherwise dispose of any of the Shares in violation of the Securities
Act of 1933, as amended.

     3.3  NEGOTIATIONS WITH OTHERS.  The Seller acknowledges and consents to the

circumstances become liable to Purchaser for any "Expenses" or "Termination
Fee", as those terms are defined in the Merger Agreement.

     3.4  PERINATAL CREDIT AGREEMENT.  The Seller shall take such actions as may
be necessary to obtain, on or before the Closing Date or the date of purchase of
Shares pursuant to the Offer, the release of the Shares from the pledge and
security interest securing Seller's guaranty of the Perinatal Credit Agreement
and to obtain any consents of the lender required thereunder.

4.   COVENANTS OF THE PARTIES FOLLOWING THE SALE OF THE SHARES

     In the event the Purchaser purchases the Shares pursuant to the Offer or
this Agreement:

     4.1  INSURANCE.  With respect to events or occurrences which precede the
earlier of the Closing Date or the date of purchase of Shares pursuant to the
Offer (the "Cut-off Date"),

                                       -5-

<PAGE>

the Company shall be entitled to the benefits of insurance coverage under the
Seller's insurance programs (a list of which was previously provided to the
Purchaser), subject to the payment by the Purchaser of any applicable premiums,
deductibles, self-insured retentions, out-of-pocket costs and expenses, or other
charge related to such coverage.  To the extent that any policies of insurance
result in additional retrospective or adjusted premium charges relating to the
Company or its employees, or the Seller becomes eligible for credits and refunds
relating to the Company or its employees, the Company shall be responsible for
any such premiums and charges and shall receive the benefits of any such credits
and refunds in accordance with Seller's past practice.  The Purchaser and the
Company acknowledge that the actual availability of insurance coverage for any
given event or occurrence will depend upon the specific terms of the applicable
insurance policy and will be subject to the possible prior exhaustion by the
Seller of the coverage under such policies in connection with claims of the
Seller unrelated to the Company.  With respect to periods ending prior to
June 1, 1995, the Seller shall use reasonable business efforts to maintain the
scope and levels of coverages and material terms and conditions in the
applicable insurance policies, including but not limited to maintaining current
retroactive dates and prior acts coverage under "claims-made" policies to the
extent it is commercially advisable to Seller to do so.  Except as provided in
the immediately preceding sentence, the parties further acknowledge that the
Seller shall be permitted to change its existing levels of insurance coverage or
terms of insurance coverage in connection with future policies of insurance
obtained by the Seller; PROVIDED, HOWEVER, that until June 1, 1997, if Seller
determines that it wishes to make a material change in the levels of its
insurance coverage, deductibles or the retroactive dates thereof, Seller shall
promptly notify Purchaser of such determination and Purchaser shall have the
right to request that Seller maintain the then existing coverage, and Seller
shall use its best efforts to do so, subject to the payment by Purchaser of the
additional premium cost to retain such existing coverage.  The Seller shall give
prompt notice to the Purchaser of any notice from any carrier, including any
change in the retroactive date of future insurance policies, that coverage for
events occurring prior to the Closing Date may not be available.  To the extent
that the insurance coverage is available, Seller agrees to purchase, at the
written request of the Company and at the sole expense of the Company, extended
reporting period ("tail insurance") coverage for the Company in accordance with
the requirements of the insurance policies with respect to any claims-made
policies insuring the Company.  Notwithstanding the foregoing, Seller shall, on
behalf of the Company, use reasonable business efforts to continue to provide
and keep in effect for a period of not less than three (3) years after the
Effective Time (as defined in the Merger Agreement) its currently existing
directors' and officers' liability coverage or other similar

                                       -6-

<PAGE>

insurance ("D&O Insurance") for the directors and officers of the Company with
respect to their acts and omissions committed prior to the Cut-off Date,
provided, however, that if between the date hereof and the Cut-off Date, the
Seller is advised by its insurance broker in writing that its currently existing
D&O Insurance, if continued in place on or after the Cut-Off Date, would not
provide coverage to all of the directors  and officers of the Company for their
acts or omissions prior to the Cut-off Date, then Purchaser shall obtain such
coverage or Seller shall, at the request of Purchaser, use all reasonable
efforts to obtain for the benefit of Purchaser such coverage, in either case at
the sole cost and expense of Purchaser.  In the event that maintaining coverage
for such directors and officers results in premiums in future years which are
greater than the premiums paid by the Seller for such coverage in the current
policy year, then  Purchaser agrees to reimburse Seller for such increased
premiums to the extent such increase is attributable to the continued coverage
of the Company's directors and officers.

     The Purchaser shall give prompt notice to the Seller of all claims made by
or against the Company that are covered by the Seller's insurance programs as
provided in this Agreement.  Upon notice of any such claim, the Seller shall
notify the appropriate insurance carrier under the Seller's insurance programs
and, in conjunction with such insurance carrier, shall have the right to direct
the investigation, negotiation and, if applicable, defense of such claim and to
settle or otherwise dispose of such claim without the consent or approval of the
Purchaser, provided that, to the extent permitted by Seller's insurance
policies, Purchaser shall have the right, at its option and at its own expense,
to direct the investigation, negotiation, defense or settlement of any claim
which, in the reasonable judgment of Purchaser, may be disposed of or settled
for an amount less than the deductible, self-retention or out-of-pocket portion
of the applicable insurance coverage.  Purchaser shall, in any event, have the
right to participate in, at its cost and expense, the investigation,
negotiation, or settlement of any claim.  The parties shall cooperate with each
other relative to the exchange of records and other information necessary for
the reporting, investigation, negotiation and, if applicable, defense of such
claim.  The Purchaser shall make its employees available as may be necessary in
connection with the investigation or defense of any such claim.

     4.2  INSURANCE CLAIMS.  Seller will assist in administration of claims and
filings with its insurance carriers, subject to the payment terms described in
this Article 4.  With respect to medical coverages, the Company shall be
responsible for the costs and expenses of its employees and shall reimburse
Seller for any such unreimbursed charges related to medical expenses incurred by
employees prior to the Cut-off Date.

                                       -7-

<PAGE>

     4.3  CONTINENTAL CREDIT AGREEMENT.  The Purchaser shall, not later than the
Cut-off Date, cause the Company to pay in full all indebtedness outstanding
under the Revolving Credit and Term Loan Agreement dated June 30, 1990 (the
"Credit Agreement") between Continental Bank N.A., LTCB Trust Company and the
Company, as amended to date.

     4.4  COOPERATION.  Each party to this Agreement shall cooperate with the
other party hereto, including the furnishing of testimony and other evidence, as
reasonably requested by any such other party, relating to the operations of the
Company prior to the Cut-Off Date.  If requested by Purchaser in writing, the
Seller shall assist the Purchaser in Purchaser's efforts to obtain consents from
third parties which are required in order to prevent the loss by the Company of
the benefits of contracts between the Company or the Seller (on behalf of the
Company) and such third parties as a result of the transactions contemplated by
this Agreement and the Merger Agreement.  In the event the Purchaser is unable
to obtain any such consent and rights under such contract revert to the Seller
or are retained by the Seller after the Cut-off Date, the Seller shall use
reasonable efforts to transfer the benefits thereunder to the Company to the
extent reasonably practicable.  Nothing in this paragraph shall be construed to
create any obligation for the Seller to compensate the Purchaser or the Company
for the loss of the benefits of any such contract.

     4.5  RECORD RETENTION.  For a period of six years after the Cut-off Date,
each party to this Agreement shall preserve all files and records relating to
the Company in its possession or control, shall allow the other party access to
such files and records and the right to make copies and extracts therefrom at
any time during normal business hours, and shall not dispose of any thereof,
provided that commencing three years after the Cut-Off Date, either party may
give the other party written notice of its intention to dispose of any part
thereof, specifying the items to be disposed of in reasonable detail.  Such
other party may, within a period of sixty days after receipt of any such notice,
notify the party proposing such disposal of such other party's desire to retain
one or more of the items to be disposed of.  The party proposing such disposal
shall, upon receipt of such a notice from the other party, deliver to the other
party, at such other party's expense, the items specified in its notice to such
other party which such other party has elected to retain.  Notwithstanding the
foregoing, after the date hereof, if Seller desires to send any files or records
relating to the Company to Purchaser, the Purchaser shall accept delivery of
such files or records.

     4.6  RETURNS AND REPORTS.  The Seller shall cooperate and cause its
employees to cooperate with the Purchaser in the preparation, in accordance with
the Purchaser's instructions, of

                                       -8-

such financial, tax and other governmental reports and statements relating to
the Company for periods ending on or prior to the Cut-Off Date as the Purchaser
may reasonably request.

     4.7  PERINATAL SUPPLY AGREEMENT.  The Seller shall, not later than the
Closing Date hereunder, cause Perinatal Services, Inc. ("PSI") to enter into an
agreement to purchase certain medical supplies (the "Perinatal Supply
Agreement") from the Company, which agreement shall be substantially in the form
of EXHIBIT A attached hereto.

     4.8  MANAGEMENT SERVICES AGREEMENT.  The Company and the Seller shall, not
later than the Closing Date hereunder, terminate the current Administrative
Services Agreement in effect between them and, not later than the Closing Date
hereunder, the Company and the Seller shall execute a Management Services
Agreement (the "Management Services Agreement") in substantially the form
attached hereto as EXHIBIT B.

services through employees of Seller or its Affiliates.

     5.2  NON-COMPETITION.

     (a)  The Seller acknowledges and recognizes the highly competitive nature
of the Infusion Care business and accordingly agrees that, to induce Purchaser
and Subsidiary to consummate the transactions contemplated by this Agreement and
the Merger Agreement, neither the Seller nor any Affiliate shall, for a period
of five (5) years from the earlier to occur of the Closing Date or the sale by
the Seller of the Shares pursuant to the Offer:  (i) engage, directly or
indirectly, in or control, directly or indirectly, any Competitive Business in
the Restricted Territory, whether such engagement or control be as an

                                      -10-

<PAGE>

employer, owner, partner, consultant or other participant in any Competitive
Business; or (ii) assist others in engaging in any Competitive Business in the
Restricted Territory (such engagement, control or assistance of others in
engaging in any Competitive Business in the Restricted Territory is hereinafter
referred to as "Competitive Activity"); PROVIDED, HOWEVER, that (y) the Seller
or any Affiliate may engage in a Competitive Activity to the extent that such
Competitive Activity arises from the acquisition by Seller or any Affiliate of
any Person engaged in a Competitive Activity and such Competitive Activity
engaged in by such acquired Person amounts to only ten percent (10%) of the
total revenue received by such acquired Person in the fiscal year prior to such
acquisition and (z) nothing in this Section 5.2 shall prevent Seller or any
Affiliate from contracting or joining with other Persons in one or more groups
or alliances which provide a variety of medical services, including Infusion
Care, as long as neither the Seller nor its Affiliates provides any Infusion
Care to or on behalf of such group or alliance.

     (b)  The restraints of this Section 5.2 shall not prohibit or restrict the
Seller from fulfilling any obligations under the Management Services Agreement
nor shall it prohibit or restrict the Seller or any Affiliate from engaging in
the Retained Business.

     5.3  NON-SOLICITATION.  The Seller covenants and agrees that for a period
of three (3) years from the earlier to occur of the Closing Date or the sale by
the Seller of the Shares pursuant to the Offer, neither the Seller nor any
Affiliate will, either for themselves or in conjunction with or on behalf of any
other person or entity solicit or attempt to solicit for employment any person
who is now or is as of the Closing Date or the date of purchase of the Shares
under the Offer an employee of the Company; provided, however, that the
restraints of this Section 5.3 shall not prohibit or restrict the Seller or any
Affiliate from hiring any employee of the Company who initiates contact with the
Seller or any Affiliate to request employment.

     5.4  NONDISCLOSURE.  The Seller agrees that for a period of four (4) years
after the earlier to occur of the Closing Date or the date of the purchase of
the Shares under the Offer, the Seller will not, without the prior written
consent of the Purchaser, disclose any Confidential Information to any third
party (other than as required by any law or regulation; PROVIDED HOWEVER, that
Seller shall use its best efforts to provide Purchaser with prior written notice
of such disclosure).  Notwithstanding the foregoing, nothing contained herein
shall (a) prohibit or restrict the Seller from fulfilling any obligations under
the Management Services Agreement; and (b) prohibit or restrict the Seller or
any Affiliate from engaging in the Retained Business or in any other business
engaged in by Seller

                                      -11-

<PAGE>

or any Affiliate other than Infusion Care, including, without limitation,
utilizing in the Retained Business or in any such other business, any
Confidential Information of the Company which has been received by the Seller or
any Affiliate prior to the Closing Date or the date of purchase of the Shares
under the Offer.

     5.5  GOODWILL COVENANT.  The Seller agrees that for a period of four (4)
years after the earlier to occur of the Closing Date or the date of purchase of
the Shares under the Offer, the Seller will refrain from making any disparaging
statements regarding Purchaser or the Company.

     5.6  INTERPRETATION.  If the scope of any restriction contained in Sections
5.2, 5.3, 5.4 or 5.5 is too broad to permit enforcement of such provisions
hereof to their full extent, then such restriction shall be enforced to the
maximum extent permitted at law and in equity, and in that event Seller hereby
consents that such scope may be judicially modified accordingly in any
proceeding brought to enforce such restriction.

     5.7  ACKNOWLEDGEMENT.  Seller hereby acknowledges and confirms that the
Seller's business extends at least throughout the Restricted Territory, and that
any activity prohibited by Sections 5.2, 5.3, 5.4 or 5.5 at any place in the
Restricted Territory would cause irreparable injury to the Company, Purchaser
and its Affiliates.  Seller also acknowledges and confirms that the length of
the non-competition period hereunder is reasonable and necessary for protection
of the Company, Purchaser and its Affiliates against injurious effects of any
violation of the provisions of Sections 5.2, 5.3, 5.4 or 5.5.

     5.8  REMEDIES.  Seller acknowledges and confirms that Purchaser's remedy at
law for any breach of any of Seller's obligations under this Article 5 would be
inadequate, and that damages would be difficult or impossible to ascertain, and
consents that temporary and permanent injunctive relief may be granted in
accordance with equity in any proceeding which may be brought to enforce any
provision of this Article 5 without the necessity of proof of actual damage.
Seller acknowledges that Purchaser has reserved and is to have the right to
prove any damages which Purchaser has incurred or suffered resulting from any
breach of any of Seller's obligations under this Article 5.

6.   CONDITIONS TO OBLIGATIONS OF EACH PARTY.  The respective obligations of
each party to effect the sale and purchase of the Shares shall be subject to the

PRIVATE AND STRICTLY CONFIDENTIAL

February 9, 1994

W. R. Grace & Co.
One Town Center Road
Boca Raton, FL 33486

Attention:  Peter Spears
            President, NMC Homecare
            A Subsidiary of W. R. Grace & Co.

Gentlemen:

You have advised us of your interest in a possible negotiated transaction
involving Healthdyne, Inc. and Home Nutritional Services, Inc. (the "Company").
In connection with your analysis of a possible negotiated transaction, you have
requested certain oral and written information concerning the Company from
officers, directors, employees and/or agents of the Company (collectively, the
"Information").  As a condition to being furnished with the Information, you
agree (and agree to cause your affiliates) to treat the Information in
accordance with the following conditions.

     1.   The Information will be used solely for the purpose of
          evaluating a possible transaction between the Company
          and you, and it will be kept confidential by you and
          your advisors; provided, however, that you may disclose
          the Information or portions thereof to those of your
          directors, officers and employees (including the
          directors, officers and employees of your subsidiaries)
          and representatives of your advisors (the persons to
          whom such disclosure is permissible being collectively
          called "Representatives") who need to know such
          Information for the purpose of evaluating your possible

<PAGE>

                                                                               2

          transaction with the Company (it being understood that
          those Representatives will be informed of the
          confidential nature of the Information and will agree
          to be bound by this agreement and shall be directed by
          you not to disclose the Information to any other
          person).

          In the event that you are requested or required (by
          oral questions, interrogatories, requests for
          Information or documents, subpoenas, civil
          investigative demands or similar processes) to disclose
          any Information supplied to you in the course of your
          dealings with the Company or its representatives, it is
          agreed that you will provide the Company with prompt
          notice of such request(s) and the documents requested
          so that the Company may seek an appropriate protective
          order and/or waive your compliance with the provisions
          of this agreement.

     2.   The term "Information" does not include any information
          which (i) is or becomes generally available to and
          known by the public (other than as a result of a
          disclosure by you or your Representatives),
          (ii) becomes available to you on a non-confidential
          basis from a source other than the Company or its
          advisors, provided that such source is not known by you
          or any of your Representatives, after reasonable
          investigation, to be bound by a confidentiality
          agreement with or other obligation of secrecy to the
          Company or (iii) has already been or is independently
          acquired or developed by you without violating any
          confidentiality agreement with or other obligation of
          secrecy to the Company.

     3.   If you do not proceed with a transaction with
          Healthdyne or the Company and if Healthdyne or the
          Company so requests, you will return promptly to the
          Company all copies, extracts or other reproductions in
          whole or in part of the Information in your possession
          or in the possession of your Representatives, except
          that you may retain a single copy of any such documents
          (other than any of the Company's Management Monthly
          Reporting Packages, any CLEAR reports and any
          information with respect to referral sources or the
          details of contracts between the Company and insurance
          companies).  It is understood that the single copy will
          be maintained at the W. R. Grace & Co. headquarters by
          its corporate legal department and that operating

<PAGE>

                                                                               3

          management will not have access to the material.  You
          will destroy all copies of any memorandum, notes,
          analyses, compilations, studies or other documents
          prepared by you or for your use based primarily on the
          Information and that you will delete information about
          and references to the Company to the extent reasonably
          practicable in any such documents which are not based
          primarily on the Information.

     4.   Without the prior written consent of the Company, you
          will not, and will direct your Representatives not to,
          except as may be required by law in the reasonable
          opinion of your legal counsel, and only after
          contacting the Company, disclose to any person either
          the fact that any investigations, discussions, or
          negotiations are taking place concerning a possible
          transaction between the Company and you, or that you
          have requested or received Information from the Company
          or, or any of the terms, conditions or other facts with
          respect to any such possible transaction, including the
          status thereof.  The term "person" as used throughout
          this agreement will be interpreted broadly to include,
          without limitation, any corporation, company,
          partnership or individual.

     5.   Until the earlier of (i) the execution by you of a
          definitive transaction agreement ("Transaction
          Agreement") or (ii) twelve months from the date of this
          agreement, you agree not to knowingly solicit for hire
          any of the executive officers or other management-level
          employees at or above the level of regional center
          manager of the Company identified by you during your
          investigation; provided that the prohibitions set forth
          in this selection shall not be deemed to be breached if
          any such employee initially contacts you for the
          purpose of discussing employment without prior
          solicitous contact from either you or your agents.

     6.   You understand and acknowledge that, except as may be
          provided in a definitive Transaction Agreement, neither
          Healthdyne nor the Company nor their respective
          advisors are making any representation or warranty,
          express or implied, as to the accuracy or completeness
          of the Information, and none of Healthdyne nor the
          Company, their respective advisors, or any of their

          your use of the Information.  Only those
          representations or warranties that are made to you in a
          definitive Transaction Agreement when, as and if it is
          executed, and subject to such limitations and
          restrictions as may be specified in such Transaction
          Agreement, will have any legal effect.

     7.   You hereby acknowledge that you are aware, and that you
          have advised or will advise your Representatives who
          are informed as to the matters which are the subject of
          this agreement, that the United States securities laws
          prohibit any person who has material, non-public
          information concerning the matters which are subject to
          this agreement from purchasing or selling securities of
          a company which may be a party to a transaction of the
          type contemplated by this agreement or from
          communicating such information to any other person
          under circumstances in which it is reasonably
          foreseeable that such person is likely to purchase or
          sell such securities.

     8.   You also understand and agree that unless and until a
          definitive Transaction Agreement has been executed and
          delivered, no contracts or agreement providing for a
          transaction shall be deemed to exist between you and
          either Healthdyne or the Company, and neither
          Healthdyne nor the Company nor you will be under any
          legal obligation of any kind whatsoever with respect to
          such transaction by virtue of this or any written or
          oral expression thereof, except, in the case of this
          agreement, for the matters specifically agreed to
          herein.  For purposes of this paragraph, the term
          definitive "Transaction Agreement" does not include an
          executed letter of intent or any other preliminary
          written agreement, nor does it include any written or
          verbal acceptance or an offer or bid on your part.

     9.   You agree that Healthdyne and the Company reserve the
          right, in their sole and absolute discretion, to reject
          any or all proposals, to decline to furnish further
          Information and to terminate discussions and
          negotiations with you at any time.  The exercise by
          Healthdyne or the Company of these rights shall not
          affect the enforceability of any provision of this
          agreement.

     10.  This agreement is for the benefit of Healthdyne and the
          Company and will be governed and construed in

          accordance with the laws of the State of Georgia.  You
          obligations under this agreement will expire two years
          from the date of this agreement, except as otherwise
          set forth herein.
