Delaware  corporation  ("Puritan-Bennett"),   pursuant  to  a  Stock  Purchase
Agreement   dated   March  31,   1998  (the   "Agreement")   by  and   between
Puritan-Bennett  and the Company.  A copy of the Agreement is attached to this

of Mallinckrodt Inc., a New York corporation.

     Included among the assets indirectly  acquired by the Company pursuant to
the  Acquisition  (the "Acquired  Assets") are the plant and equipment used by
PBASCO in its  manufacturing  business and certain  real  property in Fountain
Valley,  California.  PBASCO manufactures  commercial aircraft oxygen delivery
systems and passenger service unit components and systems and is a supplier of
air valves,  overhead  lights and  switches  for both  commercial  and general

     The purchase  price of $69.7  million,  was all in cash; the Company used

owns all of the  outstanding  capital stock of Seller,  and Seller owns all of
the  outstanding  capital  stock  of  Puritan-Bennett   Aero  Systems  Co.,  a

     B. Buyer desires to purchase from Seller all of the outstanding shares of

     C. In order to induce  Buyer to enter into this  Agreement,  Mallinckrodt
has agreed to guarantee the payment and  performance of all of the obligations
of  Seller  hereunder,  and  Buyer  would not be  willing  to enter  into this
Agreement in the absence of such  guarantee.  Such  guarantee  shall be in the
form of the Guarantee  Agreement attached hereto as Exhibit C (as executed and
delivered by Mallinckrodt, the "Guarantee Agreement"). In consideration of the
mutual covenants, agreements, representations and warranties herein contained,
the parties agree as follows:

1.      PURCHASE AND SALE OF SHARES

     1.1  PURCHASE  AND SALE.  Subject  to the terms  and  conditions  of this
Agreement,  Buyer on the Closing Date (as defined in Section 6.1 below) agrees

<PAGE>

2.      PURCHASE PRICE

     2.1 AGGREGATE  PURCHASE PRICE.  The purchase price for the Shares and the

     2.4 ADJUSTMENT TO PURCHASE PRICE. The purchase price for the Shares shall

Such amount shall be referred to herein as the "Purchase Price Adjustment" and

(GAAP) and (ii) setting forth the amount of Net Working Capital of the Company
as of the Closing Date and (b) the resulting Purchase Price Adjustment. Within
thirty (30) days  following  the delivery of the Closing  Statement to Seller,
Seller may object to the Purchase  Price  Adjustment  in writing.  Buyer shall
cause  Deloitte  & Touche to  cooperate  with  Seller to  provide  Seller  and
Seller's certified public accountants  information used to prepare the Closing
Statement and information  relating thereto. If Seller objects to the Purchase
Price Adjustment within such thirty (30) day period, the Parties shall attempt

consummation  of the  transactions  contemplated  hereby will not, in a manner
which could  materially  adversely affect the consummation of the transactions
contemplated  hereby:  

                 (a)  result  in the  breach  of any  of  the  terms  or
conditions  of, or constitute a default under or violate,  as the case may be,
the  Certificate  of  Incorporation  or  by-laws  of  Buyer,  or any  material
agreement,  lease, mortgage, note, bond, indenture,  license or other document
or undertaking,  oral or written, to which Buyer or any of its subsidiaries or

approved in writing by Buyer.

there being no shares of preferred  stock of the  Company,  $100 par value per
share, issued and outstanding as of the Closing Date. Seller will not transfer

business relations with them.

of any  development  causing a breach of any of Seller's  representations  and
warranties  herein.  The written notices  pursuant to this Section 5.3 will be
deemed  to  have  amended  the  Disclosure  Schedule,  to have  qualified  the
representations  and warranties,  and to have cured any  misrepresentation  or
breach of warranty that  otherwise  might have existed  hereunder by reason of
the  development,  provided,  however,  that  Buyer  shall  have the  right to
terminate  this  Agreement  by  reason  of  any  such  development  which  may
reasonably  be  likely  to have a  Material  Adverse  Effect  within  ten (10)
business days of receipt of written notice of the development from Seller. The

harmless  from and against any and all loss,  liability,  damage or deficiency
(including interest,  penalties and reasonable  attorney's fees) that Buyer or

covenant, undertaking or other agreement of Seller contained in this Agreement
or in any other instrument delivered pursuant hereto.

against any and all loss, liability, damage or deficiency (including interest,

incur or become  subject to  arising  out of or due to any  inaccuracy  of any
representation or the breach of any warranty,  covenant,  undertaking or other
agreement  of Buyer  contained in this  Agreement  or in any other  instrument
delivered pursuant hereto.

     8.3 SURVIVAL OF REPRESENTATIONS AND WARRANTIES; THRESHOLD, DEDUCTIBLE AND
CAP.  The   warranties  and   representations   contained  in  Sections  3.1.3
(Capitalization  of the Company)  and 3.1.7 (Good Title) and in the  Guarantee
Agreement  will  survive  the  Closing  Date and will remain in full force and
effect indefinitely.  The warranties and representations  contained in Section

will  remain in full  force and  effect  thereafter  for a period of seven and
one-half  (7 1/2) years.  The  warranties  and  representations  contained  in
Section  3.1.14  (Taxes) will survive the Closing Date and will remain in full
force and effect  thereafter until six months after the applicable  statute of

the  parties  contained  in  this  Agreement  or in any  instrument  delivered

and will remain in full force and effect  thereafter  until April 30, 1999 and
shall be effective with respect to any inaccuracy  therein or breach  thereof,
notice of which shall have been duly given within such period,  in  accordance
with  Section  8.4  hereof.   Anything  to  the  contrary   contained   herein
notwithstanding,  (i) neither  party shall assert any claim  against the other
for indemnification  hereunder with respect to any inaccuracy or breach of the
Limited  Representations  or the warranties and  representations  contained in
Section 3.1.9  (Environmental,  Health and Safety) unless and until the amount
of such claim or claims with respect thereto shall exceed $300,000  calculated
on a  cumulative  basis and not a per item basis,  and then only in respect to
<PAGE>

the excess over said  $300,000;  and (ii)  neither  party shall be entitled to
recover from the other more than an aggregate of  $20,000,000  with respect to
all claims for  indemnity or damages with respect to any  inaccuracy or breach
of  the  Limited   Representations  and  the  warranties  and  representations
contained in Section 3.1.9  (Environmental,  Health and Safety),  whether such
claims are brought under this Article 8 or otherwise.

     8.3A  BOEING LATCH INDEMNITY.   In  addition  to  its  other  indemnity
obligations  set forth in this Agreement,  Seller agrees to indemnify,  defend
and hold Buyer and the  Company  harmless  from and  against any and all loss,
liability, damage or deficiency (including interest,  penalties and reasonable
attorney's  fees) that Buyer or the  Company  may  suffer,  sustain,  incur or
become subject to arising out of the dispute with The Boeing Company disclosed
in the  Disclosure  Schedule to Section  3.1.8  regarding the  performance  of
certain  pneumatic  latches.  The  provisions of Section 8.3 will not apply to
this separate  indemnity.  The parties  agree to cooperate  with each other to
minimize any liability to Boeing in respect of these latches.

     8.3B  ENVIRONMENTAL   INDEMNITY.  In  addition  to  its  other  indemnity
obligations set forth in this Agreement and notwithstanding anything disclosed
to Buyer in the Disclosure  Schedule,  Seller agrees to indemnify,  defend and
hold  Buyer  and the  Company  harmless  from and  against  any and all  loss,
liability, damage or deficiency (including interest,  penalties and reasonable
attorney's  fees) that Buyer or the  Company  may  suffer,  sustain,  incur or
become   subject  to  arising  out  of  or  due  to  any   inaccuracy  of  any
representation or the breach of any warranty,  covenant,  undertaking or other
agreement of Seller  contained  in Section  3.1.9 of this  Agreement  (as such
Section  would read if all  references  therein to Seller's  knowledge and the
Disclosure  Schedule  and any  matters  disclosed  to Buyer by or on behalf of
Seller were deemed deleted  therefrom).  The indemnity  obligations  set forth
herein  shall be subject to the dollar  limitations  contained  in Section 8.3
above.

     8.4 NOTICE AND  OPPORTUNITY  TO DEFEND.  If there  occurs an event  which
either party  asserts is an  indemnifiable  event  pursuant to Sections 8.1 or
8.2, the party seeking  indemnification shall notify the other party obligated
to provide  indemnification (the "Indemnifying Party") promptly. If such event
involves (a) any claim or (b) the  commencement of any action or proceeding by
a third Person, the party seeking  indemnification will give such Indemnifying
Party  written  notice of such  claim or the  commencement  of such  action or
proceeding. Such notice shall be a condition precedent to any liability of the
Indemnifying  Party  hereunder  but only to the extent  that the  Indemnifying
Party is actually  prejudiced by the lack of timely notice.  Such Indemnifying
Party shall have a period of thirty (30) days within which to respond thereto.
If such Indemnifying  Party accepts  responsibility,  such Indemnifying  Party
shall be obligated to compromise or defend,  at its own expense and by counsel
chosen by the  Indemnifying  Party and  reasonably  satisfactory  to the party
seeking  indemnity,  such matter. If such Indemnifying  Party does not respond
within such thirty (30) day period or rejects  responsibility  for such matter
in  whole or in  part,  the  party  seeking  indemnification  shall be free to
pursue, without prejudice to any of its rights hereunder, such remedies as may
<PAGE>

be  available  to  such  party  under   applicable   law.  The  party  seeking
indemnification  agrees to cooperate fully with the Indemnifying Party and its
counsel in the defense against any such asserted liability.  In any event, the
party seeking  indemnification  shall have the right to participate at its own
expense in the defense of such  asserted  liability.  Any  compromise  of such
asserted  liability by the Indemnifying  Party shall require the prior written
consent of the party seeking  indemnification.  If, however, the party seeking
indemnification  refuses its consent to a bona fide offer of settlement  which
the Indemnifying Party wishes to accept, the party seeking indemnification may
continue to pursue such matter,  free of any participation by the Indemnifying
Party,  at the sole  expense  of the party  seeking  indemnification.  In such
event,  the  obligation  of  the  Indemnifying  Party  to  the  party  seeking
indemnification shall be equal to the lesser of (i) the amount of the offer of
settlement which the party seeking  indemnification refused to accept plus the
costs and  expenses  of such party  prior to the date the  Indemnifying  Party
notifies the party seeking indemnification of the offer of settlement and (ii)
the actual out-of-pocket amount the party seeking indemnification is obligated
to pay  as a  result  of  such  party's  continuing  to  pursue  such  matter.
Indemnifying  Party  shall be  entitled  to  recover  from the  party  seeking
indemnification any additional expenses incurred by such Indemnifying Party as
a result of the decision of the party seeking  indemnification  to pursue such
matter.

     8.5 REDUCTION FOR INSURANCE.  The amount which an  Indemnifying  Party is
required to pay to, for, or on behalf of any other party  (hereinafter in this
Article 8,  referred to as  "Indemnitee")  pursuant to this Article 8 shall be
reduced  (including,  without  limitation,  retroactively)  by  any  insurance
proceeds actually recovered by or on behalf of such Indemnitee in reduction of
the related indemnifiable loss (the "Indemnifiable Loss"). Amounts required to
be paid, as so reduced, are hereafter sometimes called an "Indemnity Payment."
If an  Indemnitee  shall have received or shall have had paid on its behalf an
Indemnity Payment in respect of an Indemnifiable  Loss and shall  subsequently
receive  directly  or  indirectly,  insurance  proceeds  in  respect  of  such
Indemnifiable  Loss, then such Indemnitee shall pay to such Indemnifying Party
the  amount of such  insurance  proceeds  or,  if  lesser,  the  amount of the
Indemnity Payment.

     8.6 FOREIGN  CURRENCIES.  In the event that an Indemnity Payment shall be
denominated in a currency other than United States dollars, the amount of such
payment  shall be  translated  into United  States  dollars  using the Foreign
Exchange  Rate for such  currency as of the date that notice of the claim with
respect to such Indemnifiable Loss shall have been given by the Indemnitee.

     8.7 EXCLUSIVE  REMEDY.  Buyer and Seller  acknowledge  and agree that the
indemnification  provisions in this Agreement shall be the exclusive remedy of
Buyer and Seller with respect to the Company and the transactions contemplated
hereby.

benefits (such as relocation benefits) listed in the Disclosure Schedule which
might  not  fall  within  such a  categorization  (all of the  foregoing,  the
"Employee  Benefits"),  and (3) other  obligations of Buyer in respect of such
Employee Benefits, applicable to current or former employees of the Company.

                (b) Employment  Status. The closing of the sale of the Shares 
shall cause no change in the status of the employment  (including but not
limited to the crediting of service for all purposes,  as further  detailed in
Section 9.1.1(c), in respect of the Employee Benefits) of all employees of the
Company  (exempt and nonexempt) as the same existed  immediately  prior to the
Closing Date (it being  understood that such employees shall include,  without
limitation, those on medical, disability or other leave of absence).

                (c) Continuation of Employee Benefits' Crediting of Service.
Buyer shall  provide,  or shall  cause the  Company to  provide,  for all
employees  actively  employed by the Company on the Closing Date and continued
in employment  by the Buyer or the Company  after the Closing  Date,  Employee
Benefits  comparable  to the  Employee  Benefits  provided by Buyer to its own
similarly situated employees Buyer shall grant, or cause the Company to grant,
all employees of the Company all service with the Company  credited to them in
respect  of  the  Employee  Benefits,  for  all  purposes  including,  without
limitation,  all such service  credited to them for  purposes of  eligibility,
vesting and benefit accrual under all plans.  Buyer shall assume liability for
or cause the  Company to assume  liability  for,  all such  Employee  Benefits
reflected  on  Schedule  9.1 in respect of all such  employees  and,  as well,
former employees,  including  retirees of the Company incurred or earned,  but
not paid, on or before the Closing  Date,  or incurred in connection  with the
sale of the Company and not paid as of the Closing  Date,  including,  without
limitation,  all deferred  compensation,  supplemental  and excess pension and
savings benefits,  all bonus amounts,  normal and enhanced severance benefits,
and relocation  benefits (whether or not all such Employee Benefits are vested
on the Closing Date).  Buyer agrees that any employee not actively employed on
the  Closing  Date will  receive  the  benefits  of this  Section  9.1(c) upon
returning to active employment.
<PAGE>

                  (d)  Severance.  Buyer  shall be obligated for any liability
cost or expense for  severance  arising from or relating to or claimed by
reason of the  transactions  described  herein or contemplated  hereby,  under
Seller's or the Company's  Employee  Benefit plans;  provided,  however,  that
Seller and Mallinckrodt shall remain obligated for any such liability, cost or
expense  arising  from or  relating  to or  claimed  by reason of any  special
retention bonus program provided by the Company to selected Company  employees
prior to the Closing.

                  (e) Continuation of Benefits During  Transition Period - 
Reimbursement  by  Buyer.  Notwithstanding  any  provision  herein to the
contrary, at the Buyer's election, employees of the Company and their eligible
dependents  shall remain  eligible  during a transition  period  following the
Closing Date for coverage under the employee benefit plans of Mallinckrodt and
its affiliates (except the 401(k) plan and employee  assistance plan) covering
employees  of  the  Company  immediately  prior  to  the  Closing  Date.  Such
transition   period  shall  extend  through  June  30,  1998,  unless  earlier
terminated  by the Buyer upon  written  notice to Seller.  The Buyer ;shall be
responsible  for  reimbursing  Seller  for  all  insurance  premiums  due  for
providing such continued coverage during such transition period.  Seller shall
present Buyer with monthly  invoices  reflecting the monthly premium costs for
such continued coverage during the transition period,  which invoices shall be
paid by the Buyer within thirty (30) days after Buyer's receipt thereof.

     9.2 REASONABLE EFFORTS TO CLOSE. During the period commencing on the date
of the  execution  hereof and  continuing  until the Closing  Date,  Buyer and
Seller shall use their reasonable efforts to comply promptly with all requests
or requirements which applicable federal, state or foreign law or governmental
officials  may impose on them with respect to the  transactions  which are the
subject of this Agreement,  and to consummate such transactions as promptly as
practicable.  The reasonable  efforts of Buyer and Seller shall  include,  but
shall not be limited to, good faith response,  in cooperation with each other,
to all requests for information, documentary or otherwise, by any governmental
agency pursuant to Hart-Scott or the Foreign Laws.

     9.3 DISCLOSURE

          9.3.1 Pre-Closing.  Beginning the date of this Agreement, neither 
Seller nor Buyer,  without the prior written  consent of the other,  will
make any press  release or any  similar  public  announcement  concerning  the
transactions contemplated hereby prior to Closing; provided,  however, that if
in the opinion of counsel to Buyer or Seller (which opinion shall be confirmed
in writing by such counsel) such  disclosure  is legally  required,  Buyer and
Seller will  cooperate  in preparing a press  release or releases,  and unless
both  parties  otherwise  agree  such  disclosures  shall  be  limited  to the
disclosures  so  required  in the  opinion  of  counsel.  No  written  or oral
announcements   or  private   disclosure  with  respect  to  the  transactions
contemplated  hereby will be made to any person  unrelated  to Seller or Buyer
unless  jointly  approved by Seller and Buyer.  Buyer and Seller may  disclose
information  with  respect to the  transactions  contemplated  hereby to their
employees,  agents and consultants only to the extent such persons have a need
to know such information and agree to be bound by the terms hereof relative to
the disclosure of such information.
<PAGE>

           9.3.2 Post-Closing.  After the Closing, Seller will keep all 
confidential  and  proprietary  information  ("Information")  of  Company
confidential and will not (except as required by applicable law, regulation or
legal  process),   without  Buyer's  prior  written   consent,   disclose  any
Information to any third party.  "Information"  shall not include  information
(a) which is, or becomes,  publicly available, (b) which is disclosed by Buyer
or Company to unaffiliated parties without similar restrictions,  or (c) which
is  disclosed to Seller by a third party which Seller does not know is under a
duty to Company to keep confidential.  Notwithstanding  the foregoing,  Seller
may disclose Information to the extent it is required under applicable law.

     9.4     BOOKS, RECORDS AND INFORMATION.

     9.4.1  Buyer  agrees  that all  documents  delivered  to Buyer by  Seller
pursuant to this Agreement shall be open for inspection by  representatives of
Seller at any time during regular  business hours until such time as documents
are destroyed or possession thereof is given up to the other party as provided
for in Section  9.4.2 and that  Seller may during  such  period at its expense
make such copies thereof as it may reasonably request.  Seller agrees that all
documents  that are  retained by Seller  after the  Closing  Date and that are
related to the Company  (other  than tax records of Seller)  shall be open for
inspection by  representatives  of Buyer at any time during  regular  business
hours until such time as  documents  are  destroyed or  possession  thereof is
given up to the other  party as provided  for in Section  9.4.2 and that Buyer
may during  such  period at its  expense  make such  copies  thereof as it may
reasonably request.

     9.4.2  Without  limiting the  generality of Section  9.4.1,  for a period
ending on the sixth anniversary of the Closing Date,  neither Buyer nor Seller
shall  destroy or give up  possession of any item referred to in Section 9.4.1
without first offering to the other the  opportunity,  at such other's expense
(but without any other  payment),  to obtain the same.  Thereafter  each party
shall be free to dispose of them as it deems fit provided that nothing will be
destroyed without first offering the other side the opportunity to copy.

     9.4.3  Buyer  shall use  reasonable  efforts to afford  Seller  access to
employees who were previously employees of Seller or the Company and remain in
the  employ  of the  Company,  or Buyer or its  affiliates,  as  Seller  shall
reasonably  request  for its  proper  corporate  purposes,  including  without
limitation,  the  defense  of  legal  proceedings.  Such  access  may  include
interviews  or  attendance  at  depositions  or legal  proceedings;  provided,
however,  that in any event all  out-of-pocket  expenses  (excluding wages and
salaries)  reasonably  incurred by Buyer in connection with this Section 9.4.3
shall be paid or promptly reimbursed by Seller. 

     9.5     [INTENTIONALLY OMITTED]  

     9.6 WORKERS' COMPENSATION;  LIABILITY. Schedule 9.6 hereto sets forth (a)
state workers'  compensation claims ("Workers'  Compensation  Claims") and (b)
automobile,  premises,  product and general  liability  claims  (collectively,
"Liability  Claims")  relating to the Company  which are now pending.  Without
derogating in any manner from the  obligation  hereunder of Buyer to cause the
<PAGE>

Company to fulfill all obligations of the Company, including those obligations
relating to Workers' Compensation Claims and Liability Claims and to indemnify
Seller with respect thereto,  Buyer,  through the applicable insurance carrier
or claims administrator agrees to administer  (including  defending,  settling
and paying awards) those  Workers'  Compensation  Claims and Liability  Claims
listed  on  Schedule  9.6 and  any  other  Workers'  Compensation  Claims  and
Liability  Claims made against the Company or Seller arising from  occurrences
which took place in whole or in part prior to the Closing Date. Buyer also has
the option to "buy-out"  existing  claims  using an  insurance  carrier of its
choice. Buyer agrees to reimburse Seller within thirty (30) days of receipt of
an invoice therefor for any costs and expenses which may be incurred by Seller
in  connection  with any Workers'  Compensation  Claims and  Liability  Claims
listed on Schedule  9.6,  including  any amounts paid by Seller as a result of
any settlements or awards made for such claims.  Seller shall provide to Buyer
with each invoice  reasonable  supporting  documentation.  Buyer,  through the
insurance carriers or claims administrators, can settle or resolve any and all
claims.  Seller and Buyer will  cooperate  in the  administration  of any such
claims.

     9.7  INSURANCE-PRIMARY  CASUALTY  PROGRAM.  Seller maintains at present a
series of insurance programs pursuant to which various insurance carriers have
provided  and are  providing  insurance  coverage in respect of the  Company's
business,  including  automobile  liability,  general  liability and employers
liability (the "Primary Casualty Program") and Seller and Buyer understand and
agree that Seller is not  transferring  to Buyer pursuant hereto any rights or
interests in such  Primary  Casualty  Program,  nor shall  anything  herein be
construed to require  Seller to maintain any of such coverages or limit in any
manner Seller's right to change deductible levels or other terms or conditions
thereof. As between Buyer and Seller, however, it is agreed that the following
shall apply to claims with a date of occurrence prior to the Closing Date that
are covered by the Primary Casualty Program:

           9.7.1 Uninsured Retentions. Buyer agrees that it shall be responsible
for and shall within thirty (30) days following receipt from Seller of an
invoice with supporting  documentation  reimburse  Seller for the costs of all
Uninsured  Retentions with respect to the Primary Casualty Program  coverages.
For the purposes of this Section 9.7.1,  the term Uninsured  Retentions  means
any and all  amounts  which,  under  the  operation  of the  Primary  Casualty
Program, the insured party is obligated to contribute (by means of application
of a deductible, payment under a reimbursement obligation or otherwise) to the
appropriate insurance carrier in respect of such claim. Seller shall suffer or
bear no costs,  expenses or  liability  whatsoever  with respect to any claims
related to the Company or its prior assets, business or operations.

          9.7.2 Claims  Responsibility and Procedures.  Buyer shall promptly 
notify in writing Seller of any claims against the Company, Buyer, Seller
or any of their affiliates  arising from occurrences which took place prior to
the Closing  Date  relating to the  Company or its prior  assets,  business or
operations,  and Buyer  shall be  responsible  for all such  claims  listed on
Schedule 9.7.2. To the extent coverage is available under the Primary Casualty
Program,  Buyer  shall  handle such claims  through the  applicable  insurance
carrier and to the limited  extent  required  therefor is hereby  appointed as
<PAGE>

Seller's agent in dealing with any such  applicable  insurance  carrier,  such
agency,  however,  being  subject to  revocation at any time if Buyer fails to
comply with the  provisions of this Section 9.7.  Buyer through the applicable
insurance  carrier may settle any such claim on a basis which in its  judgment
is  reasonable  provided,  however,  that Buyer  agrees not to settle any such
claim  for an amount in excess of  $50,000  without  prior  consultation  with
Seller. Seller and Buyer shall cooperate with each other in the defense of any
such claim and will keep each other informed of significant  developments with
respect thereto. Neither Buyer nor Seller will knowingly take any action which
prejudices  the other  party in the  collection  of any  applicable  insurance
proceeds.

     9.8 PERFORMANCE OF COMPANY OBLIGATIONS. Buyer agrees to cause the Company
to perform and fulfill all obligations and commitments of the Company existing
as of the Closing Date or thereafter  incurred,  all in  accordance  with this
Agreement.

     9.9  NONCOMPETITION.  (a) Seller  agrees that,  in  consideration  of the
purchase  of the  Company  by  Buyer  hereunder,  neither  it  nor  any of its
affiliates   (including  without   limitation   Mallinckrodt  or  any  of  its
affiliates)  shall,  on or prior to the date which is five (5) years after the
Closing Date,  directly or indirectly,  run, own,  manage,  operate,  control,
provide consulting services to, participate in, lend its name to, invest in or
be  connected  in any manner  with the  management,  ownership,  operation  or
control of any business,  venture or activity which competes with the business
(including  parts and accessories  therefor) being conducted or proposed to be
conducted  at the Closing Date by the Company;  provided,  however,  no Person
shall be  considered  to be in default of this Section 9.9 solely by virtue of
holding  for  portfolio  purposes  as a  passive  investor  not more than five
percent (5%) of the issued and outstanding equity securities of a corporation,
the equity  securities of which are listed or quoted on a stock exchange or an
over-the-counter  market within the United  States.  

               (b) Seller further agrees that for a period of five (5) years 
     after the Closing  Date neither it nor any of its  affiliates  (including
without  limitation  Mallinckrodt or any of its  affiliates)  will directly or
indirectly  without  the  prior  written  consent  of  Buyer,  recruit,  offer
employment,  employ,  engage as a  consultant,  lure or entice  away or in any
other manner  persuade or attempt to persuade any person who is then an active
employee of the Company to leave the employ of the Company.

     9.10 INTELLIGENT VALVE TECHNOLOGY.  Upon the request of Buyer, NPB agrees
to give  Buyer the  first  opportunity  to enter  into a  mutually  acceptable
agreement  with Buyer  whereby  Buyer and the Company are granted the right to
license,  including the right to sublicense,  for the use within the aerospace
industry of the oxygen on-demand technology currently owned by NPB.

10.     TAX MATTERS

     10.1 FEDERAL,  STATE AND LOCAL INCOME AND FRANCHISE TAXES. The applicable
income, deductions and credits with respect to the Company or its business for
all periods  ending on or before the Closing  Date will be included in the (a)
consolidated  federal income Tax Returns of the "affiliated  group" within the
meaning  of Code  Section  1504  (a),  including  the  Company  ("Mallinckrodt
Group"),  (b)  applicable  combined  or  unitary  state  and  local  income or
franchise Tax Returns of the  Mallinckrodt  Group or (c)  applicable  separate
state or local  income or  franchise  Tax Returns to be filed on behalf of the
Company  by  Seller.  Seller  and its  affiliates  will  allow  the  Buyer  an
opportunity  to review and  comment  upon  portions of such Tax Returns to the
extent they relate to the Company.  Seller shall be solely responsible for and
shall  indemnify and hold Buyer  harmless with respect to all Taxes payable by
or  allocable  to the  Company  or its  business  for all  taxable  periods or
portions  thereof ending on or before the Closing Date, but only to the extent
not reflected on the Company's financial statements on the Closing Date. Buyer
shall be solely  responsible  for and shall indemnify and hold harmless Seller
with  respect  to all  Taxes  for all  taxable  periods  or  portions  thereof
beginning  after the  Closing  Date and for  Taxes  accrued  on the  Company's
financial  statements.  Seller  shall  be  entitled  to all  refunds  of Taxes
(reduced  by any Taxes that the Buyer or the  Company is  required to pay with
respect thereto that are not reflected on the Company's financial  statements)
with  respect to the  operations  of the Company  for all  taxable  periods or
portions  thereof ending on or before the Closing Date, but only to the extent
not reflected on the Company's financial statements on the Closing Date. Buyer
shall  promptly  pay  over to  Seller,  but in no  event  later  than ten (10)
business  days  after  receipt  thereof,  any  such  refunds  received  by it.
Notwithstanding  the  foregoing,  Buyer shall not be required to seek or cause
the  Company  to seek a refund if there  would be, in  Buyer's  judgment,  any
adverse effect on the Buyer or the Company after the Closing Date. Buyer shall
be entitled  to all refunds of Taxes (or  reductions  in Tax  liability)  with
respect to operations of the Company for taxable  periods or portions  thereof
beginning after the Closing Date, and Seller shall promptly pay over to Buyer,
but in no event later than ten (10) business days after receipt  thereof,  any
such refunds (or reductions in Tax liability) received by it. The Seller shall
not be  required  to  file,  seek or  otherwise  cause  to be filed or use its
reasonable  best efforts to obtain the receipt of such refunds (or  reductions
in Tax  liability)  including  through  the filing of amended  Tax  Returns or
refund claims to the extent there would be, in Seller's judgment,  any adverse
effect on the  Seller  or  Mallinckrodt.  In the  event a  Section  338(h)(10)
Election is not made in accordance with Section 10.9 hereof, Seller will allow
Buyer an  opportunity  to review and comment  upon  amended  Tax Returns  with
respect to taxable periods ending on or prior to the Closing Date. 

     In the case of any taxable  period that  includes but does not end on the
Closing Date (a "Straddle Tax  Period"),  the Taxes accrued for the portion of
such  taxable  period  which ends on the Closing  Date shall be computed as if
such taxable  period ended on the Closing  Date.  Allocations  with respect to
Straddle Tax Periods shall be based upon Tax rates in effect as of the Closing
Date, adjusted for retroactive rate changes, if any. The taxable period of any
<PAGE>

partnership  or  other  pass-through  entity  in  which  the  Company  holds a
beneficial  interest shall be deemed to terminate on the Closing Date.  Seller
shall be solely  responsible  for and shall  indemnify and hold Buyer harmless
with  respect to the Taxes  accrued for that  portion of a Straddle Tax Period
which ends on the  Closing  Date.  Buyer shall be solely  responsible  for and
shall  indemnify and hold Seller harmless with respect to any Taxes accrued or
relating to the portion of a Tax Straddle  Period  beginning after the Closing
Date. Seller shall pay to Buyer within thirty (30) days of the date the return
for the Straddle Tax Period is required to be filed (or if later,  is actually
filed) an amount equal to the amount of Taxes for such portion of the Straddle
Tax Period as Seller is  responsible  for in accordance  with this  paragraph,
less any Taxes paid with respect to such portion of the Straddle Tax Period by
(1) Seller or any of its  affiliates  (other than the Company) at any time and
(2) the Company on or before the day before the Closing Date. If the amount of
such Taxes  previously  paid by Seller,  any of its  affiliates or the Company
exceeds the amount payable by Seller pursuant to this  paragraph,  Buyer shall
pay, or cause the  Company to pay, to Seller the amount of such excess  within
thirty  (30)  days of the date the  return  for the  Straddle  Tax  Period  is
required to be filed (or, if later,  is actually  filed).  The  payments to be
made  pursuant to this  paragraph  by Seller or Buyer  shall be  appropriately
adjusted  to reflect  any final  determination  with  respect to Taxes for the
Straddle  Tax Period and payment  shall be made within  thirty (30) days after
such final determination.

     10.2 CERTAIN CONTEST RIGHTS. Seller will use its best efforts to promptly
inform Buyer as to the commencement of any audit or proceeding with respect to
the Tax liability of the Company.  Seller will use its best efforts to provide
Buyer with all notices, correspondence, returns and other documentation with a
direct and material  bearing on any proposed  adjustment  attributable  to the
Company or its business. In the case of an audit or proceeding that relates to
taxable periods ending on or before the Closing Date, the Buyer shall promptly
inform the Seller upon receiving  notification of the commencement of any such
audit or  proceeding  and  provide  Seller with all  notices,  correspondence,
returns  and other  documentation  with a direct and  material  bearing on any
proposed adjustment  attributable to the Company or its business in such audit
or  proceeding.  The Seller  will,  at its expense,  control such  proceeding,
provided that the Seller will provide Buyer with notice of, and an opportunity
to attend (with  Buyer's tax counsel),  any meetings,  conferences , telephone
calls or other communications with the relevant Tax authorities concerning any
proposed  adjustment  to the  Company's  pre-Closing  Taxes  if such  proposed
adjustment could adversely  affect the Company after the Closing Date.  Seller
may pay,  settle,  compromise  or  concede  any  such  proposed  increases  or
decreases.  In the case of an audit or proceeding that relates to Straddle Tax
Periods, Buyer shall control such audit or proceeding, subject to the Seller's
right to  participate  at its own expense,  provided that Buyer may not settle
such audit or proceeding without the consent of the Seller, which consent will
not be unreasonably withheld.
<PAGE>

     10.3    [INTENTIONALLY OMITTED]

     10.4 TIMING DIFFERENCES.  If a Section 338(h)(10) Election is not made in
accordance  with Section 10.9 hereof,  in the event that,  as the result of an
audit or other  proceeding  concerning the liability for Taxes with respect to
the Company or its  business  for any taxable  period  ending on or before the
Closing  Date,  there is an  adjustment  as a result of which  there  shall be
allowable  to the Company for any taxable year ending after the Closing Date a
net increase in  deductions  or credits or other items of Tax benefit or a net
decrease in income or other items of tax detriment (collectively "Items of Tax
Benefit"),  then within ten (10) business days after such Items of Tax Benefit
are actually used and realized (such as receipt of a Tax refund),  Buyer shall
pay to Seller an amount equal to fifty percent  (50%) of the actual  reduction
in Taxes  resulting from the adjustment to the extent such  adjustment was not
reflected on the Company's financial statements on the Closing Date.

     10.5  COOPERATION  AND  EXCHANGE  OF  INFORMATION.  Seller and Buyer will
provide each other with such  cooperation  and  information  as either of them
reasonably  may request of the other in filing any Tax Return,  determining  a
liability for Taxes or a right to refund of Taxes or in  conducting  any audit
or other  proceeding in respect of Taxes.  Such  cooperation  and  information
shall include providing copies of all relevant Tax Returns or portions thereof
which relate to the Company,  together with accompanying schedules and related
work papers,  documents relating to rulings or other  determinations by taxing
authorities  and records  concerning  the ownership and Tax basis of property,
which either party may possess.  Each party shall make its employees available
on a mutually  convenient  basis to provide  explanation  of any  documents or
information   provided  hereunder.   Except  as  otherwise  provided  in  this
Agreement, the party requesting assistance hereunder shall reimburse the other
for any  reasonable  out-of-pocket  costs  incurred in  providing  any return,
document or other written information,  and shall compensate the other for any
reasonable costs (excluding wages and salaries) of making employees available,
upon receipt of reasonable documentation of such costs. Each party will retain
all  returns,  schedules  and work  papers and all  material  records of other
documents relating thereto, until the expiration of the statute of limitations
(including  extensions)  of the taxable  years to which such returns and other
documents  relate and,  unless such returns and other documents are offered to
the other party,  until the final  determination  of any payments which may be
required  in respect  of such years  under  this  Agreement.  Any  information
obtained  under  this  Section  shall be kept  confidential,  except as may be
otherwise  necessary  in  connection  with the filing of returns or claims for
refund or in conducting any audit or other proceeding.

     10.6  CURRENT  TAX  INFORMATION.  The  Company  shall at its own cost and
expense  fully  and  accurately  complete  and  submit  any Tax data  packages
reasonably  required by Seller  within the normal  time period for  submitting
said information by all subsidiaries of the Mallinckrodt Group.

<PAGE>

     10.8  INTERCOMPANY  TAX ACCOUNT.  All Tax sharing  agreements,  policies,
arrangements and practices between  Mallinckrodt or any of its affiliates with
respect to or involving the Company shall be terminated as of the Closing Date
and shall have no further  effect for any taxable  year  (whether  the current
year, a future year, or a past year).  Mallinckrodt  and its affiliates on the
one hand and the Company on the other shall cancel all  intercompany  accounts
relating  to Taxes  without  payment  as of the  Closing  Date.  Any powers of
attorney  with  respect  to Taxes of the  Company  currently  in force will be
terminated effective as of the Closing.

     10.9. SECTION 338(H)(10)  ELECTION.  At Buyer's option,  Mallinckrodt and
its  affiliates  will join with the Buyer in  making an  election  under  Code
section  338(h)(10) (and any  corresponding  elections under state,  local, or
foreign Tax law) (collectively,  a "Section 338(h)(10) Election") with respect
to the  purchase and sale of the Company  stock  hereunder.  Mallinckrodt  and
Seller will pay any Income Tax arising out of or resulting  from the making of
the Section  338(h)(10)  Election and will indemnify the Buyer and the Company
against any losses  arising out of any failure to pay such Income Tax.  Seller
will also pay any state, local, or foreign Income Tax (and indemnify Buyer and
the Company  against any losses  arising out of any failure to pay such Income
Tax) attributable to an election under state,  local or foreign law under Code
section  338(g) or any similar  election with respect to the purchase and sale
of the Company stock hereunder where the state, local, or foreign jurisdiction
does not provide or recognize a Section 338(h)(10) Election.  Mallinckrodt and
Seller will comply fully with all filing and other  requirements  necessary to
effect the Section  338(h)(10)  Election and section 338(g) election described
above. For purposes of this Section 10.9,  "Income Taxes means all Taxes based

and additions to tax imposed with respect thereto.

     10.10. PURCHASE PRICE ALLOCATION. The Seller and the Buyer agree that the
Buyer and BE Intellectual  Property,  Inc., subject to Seller's consent, which
shall not be  unreasonably  withheld,  will  reasonably  allocate the purchase
price to the assets of the Company in accordance  with the  provisions of Code
section  338  and  the  Treasury   Regulations   thereunder  and  the  Company
Intellectual Property. The Buyer, the Company, the Seller and their affiliates
will file all Tax Returns (including claims for refund) in a manner consistent
with such allocation.

     10.11.  INDEMNIFICATION.  Seller  shall be liable for and shall pay Buyer
and the  Company  for all Taxes:  (i)  imposed on any person  (other  than the
