                          -         NEW REPORTING OF BUSINESS LINE PROFITABILITY


         OVERLAND PARK, KS - Puritan-Bennett Corporation (PBEN:NASDAQ), after
recording charges of $4.6 million for obligations associated with
Thermo-Electron Corp.'s unsolicited tender offer, today reported a loss of
$640,000 or $.05 per share for the third quarter ending October 31, 1994.
Without the charge, earnings per share for the quarter would have been $.31 per
share, up 15% from the $.27 per share (adjusted to eliminate losses associated
with the FOxS blood gas monitoring system) for the same period last year.

                                      2

         Orders of $83,018,000 and revenues of $83,412,000 for the quarter were
up 11% over the same period last year.  For the first nine months, orders of
$245,271,000 and revenues of $247,813,000 were up 7% and 8%, respectively, over
the same period last year.

         The Company also noted that it was told by Homedco Group, Inc., one of
the nation's leading providers of home respiratory services, that
Puritan-Bennett would be selected as one of their endorsed vendors for home
care oxygen equipment.  Homedco has been in the process of upgrading its oxygen
therapy technology to achieve greater operational efficiencies.  This award is
the result of Homedco's formal bid process, and it is one of the largest
purchases of oxygen therapy equipment in Homedco's history.

         In addition, Homedco said it would work with the Company to adapt
Puritan-Bennett's CliniVision Respiratory Management System to the home care
respiratory management needs of its patients.

         SUPPLEMENTAL PRO-FORMA INFORMATION - Chairman and President Burton A.
Dole stated:  "In order to help our stockholders better understand the economic
dynamics and potential of the company's business, we have decided to begin,
with this announcement, providing supplemental information that sets forth the
company's "operating profitability" in its two lines of business -- Puritan and
Bennett.  Operating profitability is defined as earnings before interest and
taxes and before any historical restructuring or current Thermo Electron
related charges."  Mr. Dole said, "The figures below summarize results for the
two lines of business for the current and last two fiscal years:

           PURITAN - "Puritan includes our rapidly growing home care product
line as well as our medical gas and gas-related equipment and spirometry
product lines.  Aero Systems is also included because it shares one of our
larger manufacturing facilities with the Puritan Group and is relatively small.

           "Because of its rapid revenue growth (up 17% for the first nine
months of this year compared with the same period last year and average annual
growth of 15% for the 5 years ended January 31, 1994) Puritan now accounts for
about two-thirds of the company's total revenues.  Within Puritan, home care
products continue to grow at rates considerably above the overall Puritan
average.

           "For the third quarter of this year, Puritan's operating
profitability was 11% of revenues," Mr. Dole said.  "Operating profitability
has been higher (12% and 15% of revenues in FY94 and FY93, respectively) in the
recent past and we expect it to return to





   4
                                       4

recent historical levels in the future, as we realize the benefits of several
major regulatory control and compliance initiatives undertaken in the latter
part of FY94 and during FY95.  These initiatives required considerable staffing
and other resource additions as well as manufacturing process modifications.
As a result, we experienced certain significant short-run operating disruptions
and inefficiencies, which increased our costs," Mr. Dole continued.

           BENNETT - "The Bennett line of business consists of our critical
care ventilator business -- a business that continues to represent an
exceptional and long-standing customer franchise on a global basis -- as well
as our growing CliniVision(R) product line in the U.S., and our holter
monitoring and international portable ventilator product lines.

           "Since FY93, when Bennett's operating profitability equaled 9% of
revenues, revenues have declined for several reasons including difficult market
conditions, particularly in the U.S. hospital market, discontinuance of certain
older products and accessories as a result of evolving regulatory standards,
and our withdrawal from the U.S. portable ventilator market," he said.  "In
addition, Bennett has also undertaken major regulatory control and compliance
initiatives at significant cost.  Current operating profitability (2% of
revenues in the third quarter and 3% for the nine months) is not close to where
we believe it should and will be.  We believe the recent poor profitability of
Bennett will begin to reverse itself and both revenues and margins will
increase as a result of the benefits from full implementation of our regulatory
compliance initiatives, continued growth of CliniVision and service revenue and
several other positive developments.  These developments include the new
products/product enhancements recently cleared by FDA for marketing in the U.S.
and

                                       5

recently introduced internationally.  In addition, other important new products
are being developed for introduction a little over a year from now.

           "In summary, we are encouraged by the continued strong growth of
Puritan in the third quarter and believe both Puritan and Bennett are well
positioned to begin returning to historical levels of profitability.  We will
continue to build upon our unique franchise in the critical care ventilator
area while continuing to invest in and grow the exciting home care businesses
that make up the bulk of our Puritan business line," Mr. Dole said.

           Puritan-Bennett is a world leader in products related to
respiration.  These products are used in multiple health care settings and on
aircraft.
