                                                                OCTOBER 23, 1996
 
To Our Stockholders:
 
    Your Board of Directors has unanimously approved an Agreement and Plan of
Merger dated as of July 29, 1996, as amended as of October 18, 1996, whereby a
wholly owned subsidiary of Novametrix Medical Systems Inc. would combine with
Andros Holdings Inc. in a merger transaction (the "Merger") in which Andros
would become a wholly owned subsidiary of Novametrix. In the Merger, Novametrix
will issue to the stockholders of Andros, and reserve for issuance to option and
warrant holders of Andros, the following: (i) shares of Novametrix common stock
constituting 38% of the outstanding common stock of Novametrix after giving
effect to the Merger, (ii) up to an additional 5% of the shares of Novametrix
Common Stock (based upon the capitalization of Novametrix immediately after the
Merger), in the event that Andros' revenues or the combined company's
consolidated earnings before interest, taxes, depreciation and amortization for
the fiscal year ending May 3, 1998 exceed certain targets, and (iii)
anti-dilution rights enabling the holders to maintain (without additional
payment) such percentage ownership level as Novametrix options and warrants
outstanding at the time of the Merger are exercised, but without any adjustments
for other shares of Novametrix common stock or other Novametrix options and
warrants issued after the Merger.
 
    WE BELIEVE THE ANDROS MERGER IS A UNIQUE OPPORTUNITY TO INCREASE STOCKHOLDER
VALUE SIGNIFICANTLY.
 
    Andros designs, manufactures and markets non-dispersive infrared ("NDIR")
gas analyzers and sub-systems and other sensor instrumentation for medical,
automotive and environmental applications. Andros is a 98% owned subsidiary of
Genstar Capital Partners II, L.P., a private investment fund that invests in
manufacturing and services businesses.
 
    The Novametrix Board believes that the Merger represents an important
strategic opportunity for Novametrix to create a worldwide leader in the field
of gas monitoring products and sensor technology for medical applications. The
Merger will provide Novametrix with a complete line of gas monitoring products
for medical applications through the acquisition of Andros' anesthetic agent
technology and products and will give Novametrix access to a large installed
original equipment manufacturer ("OEM") customer base. Because of the resulting
increase in size, breadth of products and extent of distribution that Novametrix
will possess after the Merger, the Novametrix Board believes that Novametrix
will be able to realize significant revenue increases and cost savings which
neither company would achieve independently. The two companies' complementary
technologies and the sharing of basic research and product development resources
will increase Novametrix' ability to introduce new products to the market
quickly and provide more leverage when dealing with large hospital chains and
OEMs in today's competitive health care environment. The combined company would
have sales of $66.8 million on a pro forma basis for the fiscal year ended April
28, 1996.
 
    Management believes the Merger to be a critical step towards further
establishing the Company as a primary supplier of medical devices to acute care
providers and OEMs in today's competitive health care environment. AFTER THE
MERGER, NOVAMETRIX WILL SERVE MOST OF THE WORLD'S LARGEST MANUFACTURERS OF
MEDICAL MONITORING EQUIPMENT. THE COMBINED COMPANY WOULD BE THE WORLD'S LARGEST
OEM PROVIDER OF NDIR GAS ANALYZERS FOR MEDICAL APPLICATIONS. VIRTUALLY EVERY
DOMESTIC "NATIONAL ACCOUNT" PURCHASES THE PRODUCTS OF ONE OR MORE OF THE
COMBINED COMPANY'S OEM CUSTOMERS.
 
    Novametrix has received the written opinion of Tucker Anthony Incorporated,
our financial advisor, to the effect that, as of October 18, 1996, the exchange
ratio in the Merger is fair, from a financial point of view, to Novametrix and
its stockholders. Based in part upon the opinion of Tucker Anthony and the
strategic opportunities described above, your Board of Directors and management
have concluded that the proposed Merger is in the best interests of Novametrix
and its stockholders.

    Additional factors which lead the Board of Directors and management of
Novametrix to recommend approval of the Merger include:
 
- -  The opportunity for Novametrix to EXPAND ITS MARKET PRESENCE by broadening
   its product lines and technology base in existing and complementary product
   areas, particularly through the acquisition of Andros' anesthetic agent
   products and technology.
 
- -  The ability of Novametrix to INCREASE ITS CUSTOMER BASE through greater
   penetration of the OEM market as a result of Andros' position as a supplier
   to major OEM medical device suppliers such as Hewlett-Packard Co., Colin
   Medical Instruments Corporation and Draegerwerk.
 
- -  PRODUCT AND INDUSTRY DIVERSIFICATION within the field of gas monitoring as a
   result of Andros' presence in the automotive gas analyzer and environmental
   monitoring markets and the substantial market share held by Andros in the
   automotive gas analyzer industry segment.
 
- -  The POTENTIAL FINANCIAL BENEFITS TO NOVAMETRIX STOCKHOLDERS, including
   projected positive financial contributions to revenue, earnings per share,
   net income and cash flow resulting from the Merger.
 
- -  The results of financial analyses indicating that, based on recent stock
   prices of Novametrix common stock, the implied COST OF ANDROS IS FAVORABLE TO
   NOVAMETRIX STOCKHOLDERS.
 
- -  The INCREASED VISIBILITY of the Company within the financial community
   resulting from the Merger.
 
    Consummation of the Merger is subject to, among other things, the approval
by the Novametrix stockholders voting at the annual meeting of stockholders on
November 25, 1996 of the issuance of the shares of Novametrix common stock to be
issued in the Merger. Information concerning the meeting, the Merger and other
matters concerning Novametrix and Andros is set forth in the accompanying proxy
material. Among other matters for Novametrix stockholders to consider at the
annual meeting are approval of the Novametrix 1996 Long Term Incentive Plan, the
election of two Class A directors for the ensuing three years and the
ratification of the Board of Directors' selection of Ernst & Young LLP to serve
as Novametrix' independent auditors for the 1997 fiscal year. Because of the
importance of the Merger and such other matters to Novametrix and its
stockholders, I urge you to read this material carefully.
 
    YOUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE ISSUANCE OF
NOVAMETRIX COMMON STOCK IN CONNECTION WITH THE MERGER. SINCE YOUR VOTE IS
IMPORTANT AT THE ANNUAL MEETING OF STOCKHOLDERS, WE ASK THAT YOU PROMPTLY
COMPLETE, SIGN, DATE AND RETURN THE ENCLOSED PROXY IN THE ENCLOSED ENVELOPE.
 
    You may have received letters, a proxy statement and proxy cards from a
group calling itself variously the "13D Shareholders Group," the "13D
Shareholders Group Regarding Novametrix Medical Systems Inc." and the
"Novametrix 13D Shareholders Group." THIS GROUP, LED BY A LAWYER NAMED PAUL COTE
AND HIS ADVISORS, IS A DISSIDENT STOCKHOLDER GROUP WITH ABSOLUTELY NO
AFFILIATION WITH THE BOARD OF DIRECTORS OR MANAGEMENT OF NOVAMETRIX. Paul Cote
and his advisors are soliciting proxies to replace the two Class A Directors up
for re-election this year with himself and Vartan Ghugasian. In addition, Paul
Cote is soliciting proxies in support of a proposal to increase "shareholder
values."
 
    YOUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE AGAINST THE
COTE GROUP'S NOMINEES AND THEIR PROPOSAL FOR THE REASONS OUTLINED IN THE SECTION
OF THE PROXY STATEMENT TITLED "INTRODUCTION--PAUL COTE'S DISSIDENT 13D GROUP."
 
    WE STRONGLY URGE YOU NOT TO SIGN OR RETURN ANY OF THE GREEN PROXY CARDS YOU
RECEIVE FROM THE 13D GROUP UNTIL YOU HAVE HAD THE OPPORTUNITY TO REVIEW AND
CAREFULLY CONSIDER THE COMPANY'S PROXY STATEMENT.
 
    YOU CAN REVOKE ANY PROXY YOU HAVE SENT TO THE 13D GROUP BY SIGNING, DATING
AND RETURNING THE ENCLOSED WHITE PROXY CARD.
 
    ONLY YOUR LATEST DATED PROXY COUNTS.

    I join with your Board of Directors in urging you to vote FOR the issuance

                                    SUMMARY
 
    THE FOLLOWING IS A SUMMARY OF INFORMATION CONTAINED ELSEWHERE IN THIS PROXY
STATEMENT. THIS SUMMARY DOES NOT CONTAIN A COMPLETE DESCRIPTION OF THE TERMS OF
THE MERGER AND THE OTHER MATTERS SUMMARIZED HEREIN AND IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE FULL TEXT OF THIS PROXY STATEMENT AND THE
APPENDICES. STOCKHOLDERS ARE URGED TO READ CAREFULLY THE ENTIRE PROXY STATEMENT
AND THE APPENDICES. EXCEPT AS OTHERWISE NOTED, THE INFORMATION IN THIS PROXY
STATEMENT (I) ASSUMES THAT IMMEDIATELY PRIOR TO THE EFFECTIVE TIME (AS
HEREINAFTER DEFINED) OF THE MERGER THERE WILL BE 7,606,374 SHARES OF NOVAMETRIX
COMMON STOCK OUTSTANDING OR ISSUABLE PURSUANT TO OUTSTANDING SHARES OF
CONVERTIBLE PREFERRED STOCK, SERIES B, PAR VALUE $1.00 PER SHARE ("SERIES B
PREFERRED STOCK"), OF THE COMPANY AND 102,833 SHARES OF COMMON STOCK, PAR VALUE
$.01 PER SHARE ("ANDROS COMMON STOCK"), OF ANDROS OUTSTANDING OR ISSUABLE UPON
THE EXERCISE OF THEN OUTSTANDING OPTIONS OR WARRANTS TO PURCHASE ANDROS COMMON
STOCK, RESULTING IN AN EXCHANGE RATIO OF 45.3354 SHARES OF NOVAMETRIX COMMON
STOCK FOR EACH SHARE OF ANDROS COMMON STOCK (SEE "THE MERGER AGREEMENT--THE
MERGER-- CONSIDERATION TO BE RECEIVED IN THE MERGER"), (II) ASSUMES THAT NO
ADDITIONAL SHARES OF NOVAMETRIX COMMON STOCK ARE ISSUED TO ANDROS STOCKHOLDERS
BASED UPON ANDROS REVENUES OR THE COMBINED COMPANY'S EARNINGS BEFORE INTEREST,
TAXES, DEPRECIATION AND AMORTIZATION ("EBITDA") FOR THE FISCAL YEAR ENDING MAY
3, 1998 (SEE "THE MERGER AGREEMENT -- THE MERGER -- EARN-OUT SHARES"), AND (III)
DOES NOT GIVE EFFECT TO ANY ISSUANCES OF NOVAMETRIX COMMON STOCK TO ANDROS
STOCKHOLDERS AFTER THE MERGER PURSUANT TO CERTAIN LIMITED ANTIDILUTION RIGHTS
(SEE "THE MERGER AGREEMENT--THE MERGER--LIMITED ANTIDILUTION RIGHTS"). EXCEPT AS
OTHERWISE NOTED, ALL REFERENCES IN THIS PROXY STATEMENT TO THE ACTIVITIES,
OPERATIONS AND BUSINESS OF NOVAMETRIX OR ANDROS SHALL ALSO INCLUDE THE
ACTIVITIES, OPERATIONS AND BUSINESS OF THEIR RESPECTIVE SUBSIDIARIES. THIS PROXY
STATEMENT CONTAINS FORWARD-LOOKING STATEMENTS ABOUT NOVAMETRIX' PROJECTED
OPERATING RESULTS AFTER THE PROPOSED MERGER AND NOVAMETRIX' PLANS FOR ACHIEVING
SUCH RESULTS, INCLUDING, WITHOUT LIMITATION, STATEMENTS CONTAINING THE WORDS
"BELIEVES", "ANTICIPATES", "INTENDS", "EXPECTS" AND WORDS OF SIMILAR IMPORT. THE
COMPANY'S ABILITY TO ACHIEVE ITS PROJECTED RESULTS IS DEPENDENT ON A VARIETY OF
FACTORS, MANY OF WHICH ARE OUTSIDE OF MANAGEMENT'S CONTROL, INCLUDING, WITHOUT
LIMITATION, THOSE REFERRED TO UNDER "THE MERGER--RECOMMENDATION OF THE BOARD OF
DIRECTORS; REASONS FOR THE MERGER", "THE MERGER--MANAGEMENT AND OPERATIONS OF
NOVAMETRIX FOLLOWING THE MERGER--OPERATIONS OF NOVAMETRIX FOLLOWING THE MERGER",
"MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF NOVAMETRIX--RISKS ASSOCIATED WITH THE NOVAMETRIX BUSINESS" AND
"MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF ANDROS--RISKS ASSOCIATED WITH THE ANDROS BUSINESS". SOME OF THE
MOST SIGNIFICANT FACTORS, ALONE OR IN COMBINATION, WOULD BE THE FAILURE TO
INTEGRATE THE BUSINESSES OF ANDROS AND THE COMPANY SUCCESSFULLY, AN
UNANTICIPATED SLOWDOWN IN THE HEALTH CARE INDUSTRY OR THE ENVIRONMENTAL INDUSTRY
(AS A RESULT OF COST CONTAINMENT MEASURES, CHANGES IN GOVERNMENTAL REGULATION OR
OTHER FACTORS), UNANTICIPATED TECHNOLOGICAL DEVELOPMENTS WHICH AFFECT THE
COMPETITIVENESS OF THE PRODUCTS OF NOVAMETRIX AND ANDROS, OR THE UNANTICIPATED
LOSS OF BUSINESS. ACCORDINGLY, THERE CAN BE NO ASSURANCE THAT NOVAMETRIX WILL
ACHIEVE ITS PROJECTED OPERATING RESULTS AFTER THE PROPOSED MERGER. GIVEN THESE
UNCERTAINTIES, PROSPECTIVE INVESTORS ARE CAUTIONED NOT TO PLACE UNDUE RELIANCE
ON SUCH FORWARD-LOOKING STATEMENTS. THE COMPANY DOES NOT INTEND, AND DISCLAIMS
ANY OBLIGATION, TO UPDATE ANY SUCH FACTORS OR TO ANNOUNCE PUBLICLY THE RESULTS
OF ANY REVISIONS TO ANY OF THE FORWARD-LOOKING STATEMENTS CONTAINED HEREIN TO
REFLECT FUTURE EVENTS OR DEVELOPMENTS.
 
                            MEETING OF STOCKHOLDERS
 
    This Proxy Statement is provided in connection with the solicitation of
proxies on behalf of the Board of Directors of the Company for use at the Annual
Meeting of Stockholders (the "Meeting") to be held on November 25, 1996, and at
any adjournment or adjournments thereof. The close of business on September 27,
1996 is the record date for determining the stockholders entitled to vote at the
Meeting (the "Record Date"). This Proxy Statement and the enclosed proxy are
first being sent to holders of Novametrix Common Stock and Series B Preferred
Stock on or about October 23, 1996.
 
PURPOSES OF THE MEETING
 
    At the Meeting, the Company's stockholders will consider and take action
upon (i) a proposal to approve, pursuant to the requirements of the Nasdaq
National Market ("Nasdaq"), the issuance of the
 
                                       3
<PAGE>
number of shares of Novametrix Common Stock contemplated by the Merger Agreement
(the "Merger Proposal"); (ii) a proposal to approve the Company's 1996 Long Term
Incentive Plan; (iii) the election of two Class A directors of the Company for
the ensuing three years; (iv) a proposal to ratify the Board of Directors'
selection of Ernst & Young LLP to serve as the Company's independent auditors
for the 1997 fiscal year; and (v) such other business as may properly come
before the Meeting or any adjournment or adjournments thereof.
 
VOTING REQUIREMENTS AT THE ANNUAL MEETING
 
    The presence, in person or by proxy, of the holders of a majority of the
voting power of all the outstanding shares of Novametrix Common Stock and Series
B Preferred Stock entitled to vote at the Meeting is necessary to constitute a
quorum at the Meeting or any adjournments thereof. Directors of the Company are
elected by a plurality vote. Approval and adoption of the Merger Proposal and
approval of other matters will require the affirmative vote of a majority of the
voting power of the shares present at the Meeting, in person or by proxy, and
entitled to vote on that proposal. Abstentions and broker non-votes (as
hereinafter defined) will be counted as present for the purpose of determining
the presence of a quorum. For the purpose of determining the vote required for
approval of matters to be voted on at the Meeting, shares held by stockholders
who abstain from voting will be treated as being "present" and "entitled to
vote" on the matter and, thus, an abstention has the same legal effect as a vote
against the matter. However, in the case of a broker non-vote or where a
stockholder withholds authority from his proxy to vote the proxy as to a
particular matter, such shares will not be treated as "present" and "entitled to
vote" on the matter and, thus, a broker non-vote or the withholding of a proxy's
authority will have no effect on the outcome of the vote on the matter. A
"broker non-vote" refers to shares of Common Stock or Series B Preferred Stock
represented at the Meeting in person or by proxy by a broker or nominee where
such broker or nominee (i) has not received voting instructions on a particular
matter from the beneficial owners or persons entitled to vote and (ii) the
broker or nominee does not have discretionary voting power on such matter.
 
    As of the Record Date, there were 7,161,930 outstanding shares of Novametrix
Common Stock, each holder of which is entitled to one vote per share with
respect to each matter to be voted on at the Meeting, and 40,000 shares of
Series B Preferred Stock, the holder of which is entitled to 11 votes per share
with respect to each matter to be voted on at the Meeting. As of the Record
Date, the directors and executive officers of the Company beneficially owned
approximately 667,802 shares of Novametrix Common Stock (excluding 158,944
shares subject to exercisable options and warrants) and have advised Novametrix
that they intend to vote or direct the vote of all shares of Novametrix Common
Stock over which they have voting power for approval and adoption of the Merger
Proposal.
 
                                 THE COMPANIES
 
NOVAMETRIX
 
    Organized in 1978, the Company is engaged in the business of designing,
developing, manufacturing and marketing monitors and sensors which provide
continuous and non-invasive measurements of a patient's blood gas levels (oxygen
and carbon dioxide) and respiratory mechanics (lung pressure, flow and volume).
The Company's current product line consists of (i) capnographs--monitors which
measure the level of exhaled carbon dioxide; (ii) pulse oximeters--monitors
which measure arterial blood oxygen saturation levels and pulse rates; (iii)
transcutaneous blood gas monitors monitors which measure oxygen and carbon
dioxide levels through the skin; (iv) a respiratory mechanics monitor--a monitor
which measures pressure, flow and volume in a patient's airway and lungs; and
(v) reusable and disposable sensors and adapters, related accessories and
replacement parts. Novametrix is a Delaware corporation with executive offices
at 56 Carpenter Lane, Wallingford, Connecticut 06492 (telephone: (800)

ANDROS
 
    Andros designs, manufactures and markets non-dispersive infrared ("NDIR")
gas analyzers and sub-systems and other sensor instrumentation for medical,
automotive and environmental applications. Andros markets its NDIR products on a
worldwide basis to many of the leading original equipment manufacturers of
medical respiratory monitoring and automotive diagnostic equipment including
Hewlett-Packard Co., Siemens Medical Systems, Inc., Colin Medical Instruments
Corporation, SPX Corp. (Automotive Diagnostics and OTC Corp.), Snap-on Tools
Incorporated, Technotest S.R.L., Sagem Souriau Systems, Grundig Professional
Electronic GmbH, Computer Aided Services, Inc., Kontron Instruments Ltd., AVL
List GmbH and Actron Manufacturing Co.
 
    In general, these companies incorporate Andros' products into their own
systems which they in turn sell to end users. Andros' NDIR products detect the
presence and measure the concentration of a variety of multi-component gas
streams.
 
    In medical applications, Andros' NDIR systems are used to detect and measure
the level of halogenated hydrocarbons ("anesthetic agents"), carbon dioxide,
oxygen, and nitrous oxide in the inspired and expired breath of patients in
operating room, recovery room and intensive care unit environments. In
automotive applications, Andros' NDIR systems are used to detect and measure the
level of carbon monoxide, carbon dioxide, hydrocarbons, oxygen and oxides of
nitrogen in automobile exhaust. In December 1993, Andros Incorporated ("Andros
Inc."), now a wholly owned subsidiary of Andros, expanded its product line
through the acquisition of Scitec Corporation, a Delaware corporation
("Scitec"), which designs, manufactures and sells spectrum analysis instruments
that analyze the elemental composition of a material in its natural location and
condition using x-ray fluorescence ("XRF") technology. These products are sold
to end users principally for detection of lead in paint.
 
    Andros is a 98% owned subsidiary of Genstar Capital Partners II, L.P., a
Delaware limited partnership ("Genstar"). Genstar is a private investment fund
that concentrates on acquisitions of manufacturing and services businesses.
 
                                   THE MERGER
 
EFFECT OF THE MERGER; CONSIDERATION
 
    Upon consummation of the Merger pursuant to the Merger Agreement,
Acquisition will be merged with and into Andros, and Andros will become a wholly
owned subsidiary of Novametrix and all of the issued shares of Andros Common
Stock outstanding immediately prior to the Effective Time will be converted into
the right to receive (i) fully paid and nonassessable shares of Novametrix
Common Stock consisting in the aggregate of 38% of the shares of Novametrix
Common Stock outstanding immediately after the Effective Time, (ii) up to an
additional 5% of the shares of Novametrix Common Stock (based upon the
capitalization of Novametrix immediately after the Merger), in the event that
Andros' revenues or the combined company's consolidated EBITDA for the fiscal
year ending May 3, 1998 exceed certain targets, and (iii) certain limited
antidilution rights (the "Rights"), provided that cash will be paid in lieu of
issuing any fractional shares of Novametrix Common Stock. See "The Merger
Agreement--The Merger-- Consideration to Be Received in the Merger", "The Merger
Agreement--The Merger--Earn-Out Shares", "The Merger Agreement--The Merger
Limited Antidilution Rights" and "The Merger Agreement--The Merger--Fractional
Shares".
 
RECOMMENDATIONS OF THE BOARD OF DIRECTORS; REASONS FOR THE MERGER
 
    The Board of Directors of Novametrix (the "Novametrix Board") believes that
the Merger is fair to and in the best interests of Novametrix and its
stockholders. Accordingly, the Novametrix Board has approved and adopted the
Merger and the Merger Agreement and unanimously recommends that the Company's
stockholders vote in favor of the Merger Proposal.
 
    In reaching its conclusion to enter into the Merger Agreement and recommend
approval of the Merger Proposal by its stockholders, the Company's Board of
Directors considered a number of factors.
 
                                       5
<PAGE>
The Novametrix Board believes that the Merger represents a unique strategic
opportunity for Novametrix to create a worldwide leader in gas monitoring
products. Because of the increase in size, breadth of products and extent of
distribution that the Company will possess after the Merger, the Novametrix
Board believes that Novametrix will be able to realize significant increases in
revenues and cost savings opportunities which neither company would achieve
independently. The two companies' complementary technologies and the sharing of
basic research and product development resources should significantly increase
Novametrix' ability to introduce new products to the market quickly. The
Novametrix Board also believes that the Merger will significantly enhance the
Company's ability to market its products to hospital chains and OEMs in today's
competitive health care environment.
 
    The recommendation of the Novametrix Board also is based on a number of
other factors, which are discussed below in the section "The
Merger--Recommendation of the Board of Directors; Reasons for the Merger".
 
OPINION OF NOVAMETRIX' FINANCIAL ADVISOR
 
    Tucker Anthony Incorporated ("Tucker Anthony") has been retained by the
Company to act as financial advisor to the Company in connection with the
Merger. On October 18, 1996, Tucker Anthony delivered a written opinion to the
effect that, as of the date of such opinion and based upon and subject to
certain matters stated therein, the exchange ratio in the Merger is fair, from a
financial point of view, to the Company and its stockholders. The full text of
the written opinion of Tucker Anthony, which sets forth the assumptions made,
procedures followed and matters considered in, as well as limits of, its review
is attached hereto as Appendix B and is incorporated by reference herein.
Holders of Novametrix Common Stock and Series B Preferred Stock are urged to
read such opinion in its entirety. See "The Merger-- Opinion of Novametrix'
Financial Advisor".
 
MANAGEMENT AND OPERATIONS OF NOVAMETRIX FOLLOWING THE MERGER
 
    At the Effective Time, the Board of Directors of the Company intends to
increase the number of directors and appoint new directors such that the Board
of Directors of the Company will be comprised of all of the members of the
Company's Board of Directors at the Effective Time, or such smaller number of
such members as may result from director resignations effective at the Effective
Time, and an equal number of directors appointed by the Board of Directors of
Andros prior to the Effective Time, one of whom will be Richard D. Paterson,
Chairman of Andros and a Managing Director of Genstar Capital LLC, the general
partner of Genstar. The Board of Directors of the Company also intends to elect
Mr. Paterson as Chairman of the Board of the Company. The continuing members of
the Board of Directors of the Company and the members appointed by the Board of
Directors of Andros will be as equally distributed as possible among Class A,
Class B and Class C directors of the Company. At the Effective Time, each
committee of the Board of Directors of the Company will be composed of an equal
number of the continuing members of the Board of Directors of the Company and
the members appointed by the Board of Directors of Andros. Each of the executive
officers of Novametrix is expected to continue as an executive officer of
Novametrix after the Merger.
 
    The Novametrix Board believes that the Merger represents a unique strategic
and financial opportunity for Novametrix to create a worldwide leader in gas
monitoring products. Because of the resulting increase in size, breadth of
products and extent of distribution that the Company will possess after the
Merger, the Novametrix Board believes that Novametrix will be able to realize
significant revenue increases and cost savings which neither company would
achieve independently. The combined company would have sales of $66.8 million on
a pro forma basis for the fiscal year ended April 28, 1996, as compared to
Novametrix' stand-alone sales of $25.3 million for the same period. Management
believes the Merger to be a critical step towards further establishing the
Company as a primary supplier of medical devices to acute care providers and
OEMs in today's competitive health care environment.

INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    The Company and Genstar have entered into a Voting Agreement (the "Voting
Agreement"), effective upon the consummation of the Merger, pursuant to which,
in any written consent or meeting of stockholders of the Company prior to
January 1, 1999, Genstar and, except as set forth below, the purchasers or
transferees of shares of Novametrix Common Stock issued to Genstar pursuant to
the Merger (the "Genstar Shares") will vote the Genstar Shares in favor of a
Board of Directors of the Company, at least one-half of whose members shall be
nominated by a majority of the current directors of the Company who continue to
be directors of the Company on (i) the date such consent is executed, (ii) the
date that notice of such meeting is mailed to stockholders of the Company or
(iii) if no such notice is mailed, the date of such meeting; provided that no
more than two of such nominees may be members of the management of the Company
and that Genstar will not be required under the Voting Agreement to vote in
favor of a Board of Directors of the Company less than half of whose members are
nominees of Genstar. Genstar Shares which are sold to the public pursuant to (i)
an effective registration statement under the Securities Act of 1933, as amended
(the "Securities Act"), or (ii) the exemption from registration provided by Rule
144 under the Securities Act thereupon will cease to be Genstar Shares. A copy
of the Voting Agreement is attached hereto as Appendix C. See "The Merger
Agreement--Other Agreements".
 
    As of September 27, 1996, Novametrix' directors and executive officers and
their affiliates beneficially owned approximately 9.1% (including shares subject
to then exercisable options and warrants) of the outstanding voting securities
of Novametrix. For a discussion of the vote required for the approval of the
Merger by the holders of Novametrix Common Stock and Series B Preferred Stock,
see "Meeting of Stockholders" above.
 
    The Novametrix Board was aware of the foregoing interests and considered
them, among other matters, in approving and adopting the Merger Agreement and
the transaction contemplated thereby.
 
ACCOUNTING TREATMENT
 
    It is anticipated that the Merger will be accounted for by the Company as a
purchase in accordance with APB No. 16 "Business Combinations", as such term is
used under generally accepted accounting principles, for accounting and
financial reporting purposes. Under the purchase method of accounting, assets
and liabilities of Andros would be recorded at their fair value at the Effective
Time, with the excess of the purchase price and certain costs related to the
Merger over the net tangible and identifiable intangible assets acquired being
recorded as goodwill.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
    The Merger is intended to qualify, for federal income tax purposes, as a
"tax-free" reorganization. It is a condition to consummation of the Merger that
each of Novametrix and Andros will have received opinions of counsel to the
effect that the Merger will constitute a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code").
For a further discussion of federal income tax consequences of the Merger, see
"The Merger--Certain Federal Income Tax Consequences of the Merger".
 
NO DISSENTERS' RIGHTS
 
    The holders of Novametrix Common Stock and Series B Preferred Stock are not
entitled to dissenters' appraisal rights in connection with, or as a result of,
the Merger.

                              THE MERGER AGREEMENT
 
EFFECTIVE TIME OF THE MERGER
 
    If the Merger is approved by the requisite vote of the stockholders of
Novametrix and the other conditions to the consummation of the Merger are
satisfied or, where permissible, waived, the Merger will become effective at the
time a certificate of merger is duly filed with the Secretary of State of the
State of Delaware or at such later time as may be specified in such certificate
(the "Effective Time"). It is anticipated that the certificate of merger will be
so filed as soon as practicable after the satisfaction or, where permissible,
waiver of the conditions noted below.
 
CONDITIONS TO CONSUMMATION OF THE MERGER
 
    The obligations of Novametrix and Andros to consummate the Merger are
subject to the satisfaction or, where permissible, waiver of certain conditions
set forth in the Merger Agreement, including obtaining the requisite approval by
the Company's stockholders of the Merger Proposal; the absence of any injunction
or enactment of any law prohibiting the consummation of the Merger; the receipt
of legal opinions with respect to certain federal income tax matters; and the
restructuring of certain indebtedness.
 
    The consummation of the Merger is also subject to the expiration or
termination of the relevant waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"). Under the HSR Act and the
rules promulgated thereunder by the Federal Trade Commission (the "FTC"), the
Merger may not be consummated until notifications have been given and certain
information has been furnished to the Antitrust Division of the Department of
Justice (the "Antitrust Division") and the FTC and specified waiting period
requirements have been satisfied. Novametrix and Genstar each filed with the
Antitrust Division and the FTC a Notification and Report Form (the "Notification
and Report Form") with respect to the Merger on August 26, 1996. As a result of
early termination, the initial waiting period for each of these filings expired
on September 4, 1996.
 
    The obligations of the Company and Acquisition to consummate the Merger are
subject to certain additional conditions, including (i) the accuracy of the
representations and warranties in all material respects of Andros contained in
the Merger Agreement, (ii) the performance by Andros in all material respects of
its obligations under the Merger Agreement to be performed by it at or prior to
the Effective Time, except to the extent that failure to comply with or perform
any such obligation would not have a Material Adverse Effect (as defined in the
Merger Agreement) on Andros and its subsidiaries taken as a whole, (iii) the
receipt of certain consents and (iv) the execution by Genstar of the Voting
Agreement. The Voting Agreement was executed by Genstar on October 21, 1996.
 
    The obligations of Andros to consummate the Merger are subject to certain
additional conditions, including (i) the accuracy of the representations and
warranties in all material respects of the Company and Acquisition contained in
the Merger Agreement, (ii) the performance by the Company and Acquisition in all
material respects of their obligations under the Merger Agreement to be
performed by them at or prior to the Effective Time, except to the extent that
failure to comply with or perform any such obligation would not have a Material
Adverse Effect on the Company and its subsidiaries taken as a whole, (iii) the
approval of the Merger by the Company's stockholders, (iv) the receipt of
certain consents and (v) the execution by Novametrix of a Registration Rights
Agreement in the form attached hereto as Appendix D (the "Registration Rights
Agreement").
 
TERMINATION OF THE MERGER AGREEMENT
 
    The Merger Agreement may be terminated and the Merger may be abandoned at
any time prior to the Effective Time (notwithstanding any approval of the Merger
Agreement by the stockholders of Andros or the Company): (i) by mutual written
consent of Andros and the Company; (ii) by either Andros or the Company, if the
Merger is not consummated by March 31, 1997 (provided that the right to
terminate the Merger Agreement at such date will not be available to any party
whose failure to fulfill any of its obligations under the Merger Agreement is
the cause of or results in the failure to consummate the
 
                                       8
<PAGE>
Merger by such date); (iii) by either Andros or the Company, if any applicable
domestic law, rule or regulation makes consummation of the Merger illegal or
otherwise prohibited or if any judgment, injunction, order or decree of a court
of competent jurisdiction restrains or prohibits the consummation of the Merger,
and such judgment, injunction, order or decree becomes final and nonappealable;
(iv) by either Andros or the Company, if stockholder approval of the Merger
Proposal by the stockholders of the Company is not obtained by reason of the
failure to obtain the requisite vote upon a vote at a duly held meeting of
stockholders or at any adjournment thereof; (v) by Andros, if the Board of
Directors of the Company or any committee thereof with the power to do so
withdraws or modifies in a manner adverse to Andros its approval or
recommendation of the Merger Agreement, the Merger or any other transaction
contemplated by the Merger Agreement or recommends, takes a neutral position
with respect to, is unable to take a position with respect to or fails to reject
another merger, consolidation or business combination with, or acquisition of,
the Company or its assets or another tender or exchange offer for shares of
Novametrix Common Stock, or resolves to do any of the foregoing; (vi) by either
Andros or the Company (the "Terminating Party"), if (x) there is a breach by the
other party of any representation or warranty contained in the Merger Agreement
which would have or would be reasonably likely to have a Material Adverse Effect
upon the Company or Andros and their respective subsidiaries taken as a whole,
as the case may be, or (y) is a material breach of any of the covenants or
agreements set forth in the Merger Agreement on the part of the other party,
which breach is not curable or, if curable, is not cured within 30 days after
written notice of such breach is given by the Terminating Party to the other
party; or (vii) by Andros, if it is disclosed or Andros otherwise learns that
ownership of an aggregate of 50% or more of the then outstanding shares of
Novametrix Common Stock has been acquired by any person and such person's
affiliates, other than Genstar or its affiliates.
 
    For a description of the fees and expenses payable by each party in
connection with the Merger, see "The Merger Agreement--Fees and Expenses".

    At the Effective Time, each outstanding option to purchase Andros Common
Stock (an "Andros Option") issued pursuant to the Andros Stock Option Plan,

conditions as were applicable under such Andros Option, (i) (x) the same number
of whole shares of Novametrix Common Stock as the holder of such Andros Option
would have been entitled to receive pursuant to the Merger had such holder
exercised such option in full immediately prior to the Effective Time and (y) a
number of Rights equal to the number of Rights which the holder of such Andros
Option would have been entitled to receive pursuant to the Merger had such
holder exercised such option in full immediately prior to the Effective Time,
(ii) at a price per share (rounded up to the nearest whole cent) equal to (A)
the aggregate exercise price for the shares of Andros Common Stock otherwise
purchasable pursuant to such Andros Option divided by (B) the number of whole
shares of Novametrix Common Stock deemed purchasable pursuant to such Andros
Option.
 
    At the Effective Time, each outstanding warrant to purchase shares of Andros
Common Stock (an "Andros Warrant") shall be assumed by the Company. Each Andros
Warrant shall be deemed to constitute a warrant to acquire, on the same terms
and conditions as were applicable under such Andros Warrant, (i) the same number
of whole shares of Novametrix Common Stock as the holder of such Andros Warrant
would have been entitled to receive pursuant to the Merger had such holder
exercised such warrant in full immediately prior to the Effective Time and (y) a
number of Rights equal to the number of Rights which the holder of such Andros
Warrant would have been entitled to receive pursuant to the Merger had such
holder exercised such warrant in full immediately prior to the Effective Time,
(ii) at a price per share (rounded up to the nearest whole cent) equal to (A)
the aggregate exercise price for the shares of Andros Common Stock otherwise
purchasable pursuant to such Andros Warrant divided by (B) the number of whole
shares of Novametrix Common Stock deemed purchasable pursuant to such Andros
Warrant. No additional consideration shall be required to be paid with respect
to the Rights.

(1) On March 26, 1996, Andros Acquisition Inc., a wholly owned subsidiary of
    Andros ("Andros Acquisition"), closed a public tender offer for all of the
    shares of Andros Inc. for $18.00 per share (the "Tender Offer"). As a result
    of the Tender Offer, Andros Acquisition acquired approximately 58% of the
    outstanding shares of Andros Inc. At this time, Andros initiated the process
    whereby it would acquire the remaining Andros Inc. shares it did not own
    through a merger of Andros Acquisition and Andros Inc. which it could cause
    to happen as a result of Andros Acquisition owning a majority of the then
    outstanding shares of Andros Inc. As a consequence of the pending merger,
    Andros accrued the cost of acquiring the remaining Andros Inc. shares
    outstanding and cashing out the outstanding options. On May 14, 1996, Andros
    acquired substantially all of the remaining shares of Andros Inc. as a
    result of the merger of Andros Acquisition with and into Andros Inc. in
    which Andros Inc. became a wholly owned subsidiary of Andros. The
    accompanying consolidated financial statement data include the financial
    statement data of Andros Inc. from July 31, 1995 through March 26, 1996 and
    Andros, including its subsidiary, Andros Inc., from March 27, 1996 through
    July 31, 1996. The selected financial data of Andros and Andros Inc. are
    qualified in their entirety by, and should be read in conjunction with, the
    financial statements of Andros and Andros Inc., including the notes thereto,
    and "Management's Discussion and Analysis of Financial Condition and Results
    of Operations of Andros" included elsewhere herein. The Statement of
    Operations Data and Balance Sheet Data for the years ended July 31, 1996,
    July 30, 1995, July 31, 1994 and July 25, 1993, and for the period from July
    31, 1995 to March 26, 1996 and the Balance Sheet Data as of July 31, 1996,
    July 30, 1995 and July 31, 1994 are derived from, and are qualified by
    reference to, the audited financial statements included elsewhere in this
    Proxy Statement. The Statement of Operations Data and Balance Sheet Data for
    the fiscal year ended July 26, 1992 are derived from audited financial
    statements not included herein.
 
(2) Andros acquired the outstanding common shares of Andros Inc. in a cash
    purchase effective March 26, 1996. The purchase was recorded in accordance
    with APB No. 16 "Business Combinations". See Note 1 on page F-20, "Basis of
    Presentation."
 
(3) Not applicable, since Andros was a closely-held private company effective
    March 26, 1996.
 
(4) Unaudited.

                    PRO FORMA COMBINED FINANCIAL INFORMATION
 
    The following unaudited Pro Forma Consolidated Condensed Balance Sheet as of
July 28, 1996 gives effect to the Merger assuming it had occurred at that date.
The unaudited Pro Forma Consolidated Condensed Statements of Operations for the
three month period ended July 28, 1996 (Andros for the three months ended July
31, 1996) and the year ended April 28, 1996 give effect to the Merger as if it
had occurred as of May 1, 1995. The pro forma information assumes the Merger
will be accounted for under the purchase method of accounting and includes the
effects of the assumptions and adjustments described in the accompanying notes
to the pro forma consolidated condensed financial statements. The pro forma
adjustments which give effect to the Merger are referred to as Pro Forma
Adjustments (Novametrix).
 
    Additionally, the unaudited Pro Forma Consolidated Condensed Statements of
Operations for the three month period ended July 28, 1996 and the year ended
April 28, 1996 give effect to the acquisitions of the common shares of Andros
Inc. by Andros, which occurred between March 26, 1996 and May 14, 1996, as if
such acquisitions had occurred as of May 1, 1995. The pro forma information
gives effect to these transactions under the purchase method of accounting and
to the assumptions and adjustments described in the accompanying notes to the
pro forma consolidated condensed financial statements. The pro forma adjustments
which give effect to the acquisition of Andros Inc. by Andros are referred to as
Pro Forma Adjustments (Andros).
 
    The pro forma consolidated condensed financial statements should be read in
conjunction with the historical audited and unaudited financial statements and
related notes thereto of Novametrix, Andros and Andros Inc. included elsewhere
in this Proxy Statement or incorporated herein by reference. These pro forma
statements are presented for informational purposes only and are not necessarily
indicative of the results that actually would have occurred had the pro forma
transactions been consummated at the dates indicated, nor are they necessarily
indicative of the future operating results or financial position of Novametrix.
In addition, they are not intended to be a projection of future results and do
not include any synergies that might be achieved from combining the operations
of the two companies. Permitted pro forma adjustments include only the effects
of events directly attributable to a transaction that are factually supportable
and expected to have a continuing impact. Pro forma adjustments reflecting
anticipated "efficiencies" in operations resulting from a transaction are, under
most circumstances, not permitted. As a result of the limitations imposed with
regard to the types of permitted pro forma adjustments, management believes that
this unaudited pro forma information is not indicative of future results of
operations.

(a) Reflects $9.4 million of charges and costs incurred by Andros Inc. in
    conjunction with, but not directly related to, the acquisition. These
    charges and costs relate to accounts receivable, inventories, product
    warranty, property taxes and other liabilities. Charges of $5.0 million,
    $0.4 million and $4.0 million are included in cost of products sold,
    research and product development and selling, general and administrative,
    respectively.
 
                                                                  (SEE ENDNOTES)

- ------------------------------
 
(1) Under the Merger Agreement, Novametrix will issue to the stockholders of
    Andros shares of Novametrix Common Stock constituting 38% of the combined
    company at the Effective Time of the Merger. After the end of Novametrix'
    fiscal year ending May 3, 1998, additional shares of Novametrix Common Stock
    constituting up to 5% of the Company may be issued, and reserved for
    issuance to option and warrant holders of Andros, based upon Andros' net
    revenues or the combined company's consolidated EBITDA. In addition,
    Novametrix will issue to the stockholders of Andros anti-dilution Rights
    enabling the holders to maintain, without additional payment, their
    percentage ownership level as Novametrix options and warrants outstanding at
    the Effective Time of the Merger are exercised. The Pro Forma Consolidated
    Condensed Balance Sheet reflects the assumed issuance of 4,389,586 shares of
    Novametrix Common Stock (based on the outstanding shares of Novametrix at
    July 28, 1996) in exchange for all outstanding shares of Andros Common
    Stock. The number of shares of Novametrix Common Stock to be issued is based
    upon the exchange ratio of 48.8818 shares of Novametrix Common Stock for
    each share of Andros Common Stock. The actual number of shares of Novametrix
    Common Stock to be issued in the Merger will be determined at the Effective
    Time of the Merger. The market value of a share of Novametrix Common Stock
    is assumed to be $5.75 per share (the Nasdaq closing price per share at July
    26, 1996).
 
(2) Earnings per share for the period and the year presented are based on the
    weighted-average number of shares of Novametrix Common Stock and dilutive
    common stock equivalents outstanding during the year. Common stock
    equivalents consist of Series B Preferred Stock, stock options, warrants and
    shares subscribed under the Novametrix Employee Stock Purchase Plan, (the
    "Stock Purchase Plan"). The weighted average shares presented on both the
    Pro Forma Consolidated and Pro Forma Consolidated Assuming Anti-Dilution
    Provisions information includes all shares which are contingently issuable
    pursuant to the Rights and the outstanding warrants of Andros which will be
    converted to Novametrix warrants.
 
(3) The Pro Forma Consolidated Condensed Balance Sheet as of July 28, 1996
    reflects Andros' balances as of July 31, 1996. The Pro Forma Consolidated
    Statement of Operations for the three month period ended July 28, 1996
    reflects Novametrix' results of operations for the three month period ended
    July 28, 1996 and Andros' results of operations for the three month period
    ended July 31, 1996. The Pro Forma Consolidated Statement of Operations for
    the year ended April 28, 1996 reflects Novametrix' results of operations for
    its fiscal year ended April 28, 1996 and the results of operations for
    Andros Inc. and Andros for the year ended April 30, 1996.
 
(4) Genstar created Andros expressly for the purpose of acquiring Andros Inc., a
    public company traded on the Nasdaq. On March 26, 1996, Andros Acquisition,
    a wholly owned subsidiary of Andros, closed the Tender Offer for all of the
    shares of Andros Inc. for $18.00 per share. As a result of the Tender Offer,
    Andros Acquisition acquired approximately 58% of the outstanding shares of
    Andros Inc. At this time Andros initiated the process whereby it would
    acquire the remaining Andros Inc. shares it did not own, through a merger of
    Andros Acquisition and Andros Inc. which it could cause to happen as a
    result of Andros Acquisition owning a majority of the then outstanding
    shares of Andros Inc. As a consequence of the pending merger, Andros accrued
    the cost of acquiring the remaining Andros Inc. shares outstanding and
    cashing out the outstanding options. On May 14, 1996, Andros acquired 100%
    of the shares of Andros Inc. as a result of the merger of Andros Acquisition
    with and into Andros Inc. in which Andros Inc. became a wholly owned
    subsidiary of Andros (the "Andros Merger"). Before the closing of the Andros
    Merger, certain stockholders (the "Dissenters") representing approximately
    723,000 shares of Andros Inc. exercised their appraisal rights (under
    Delaware corporate law). As part of the financing for the Andros Merger,
    Andros borrowed $27,000,000 in the form of a term loan (the "Term Loan")
    from a syndicate of banks (the "Banks"). As a result of the Dissenters
    seeking appraisal rights for their shares, Andros did not have to fund the
    purchase of the Dissenters' shares at the time of the Andros Merger and had
    approximately $7,000,000 of excess cash. In early June 1996, in an effort to
    reduce its interest costs, Andros agreed with the Banks to repay $7,000,000
    of the Term Loan with the understanding that it would be able to re-borrow
    the same amount at a later date. On July 12, 1996 the Dissenters withdrew
    their appraisal rights. At that time, Andros paid the Dissenters
    approximately $13,031,000, which it financed through re-borrowing the
    $7,000,000 it had repaid on the Term Loan in June, the drawing of
    approximately $5,400,000 under a revolving credit facility established with
    the Banks at the time of the Andros Merger (the "Revolving Credit Facility")
    and with approximately $631,000 of cash on hand.
 
(5) To give effect to an increase in interest expense assuming the $27.0 million
    variable rate term debt (currently 8.5%), the $15.0 million 13% subordinated
    debt, and the $5.4 million variable rate credit facility (currently 10%)
    used in the financing of the Andros Merger had been outstanding as of May 1,
    1995.
 
(6) To give effect to a reduction in interest income assuming the use of $26.0
    million of the cash of Andros Inc. used in the financing of the Andros
    Merger had occurred as of May 1, 1995.
 
(7) Andros acquired Andros Inc. on March 26, 1996 in a transaction accounted for
    as a purchase and recorded a $22.7 million non-recurring write-off of
    in-process technology during the period from March 27, 1996 to April 30,
    1996.
 
(8) Assumes the Andros Merger occurred as of May 1, 1995 and the resulting
    goodwill and purchased technology of $21.3 million was amortized beginning
    May 1, 1995 using a twenty-five year amortization period. The Pro forma
    adjustment represents the incremental amortization. Pro forma goodwill and
    patent amortization is $844,000 and $197,000, respectively.
 
(9) To reflect the increase in depreciation expense due to the fair market
    adjustment to fixed assets of $2.5 million resulting from the Andros Merger.
    These assets are being depreciated over their remaining useful lives, which
    average approximately five years.
 
(10) To give effect to the amortization of $3.8 million in loan origination
    costs and $1.4 million in debt discounts associated with the Andros Merger.
    The fees and discount are being amortized over the term of the loan (5
    years). Pro forma amortization of fees and discount is $707,000 and
    $345,000, respectively.

       Reflects the elimination of two senior officers in conjuction with the
       Andros Merger.
 
    (b) Elimination of the European Service Center
       The cost savings resulted from the elimination of the European service
       center located in Belp, Switzerland in April 1996.
 
    (c) Elimination of Public Reporting Requirements
       Costs eliminated due to the absence of public reporting requirements
       resulting from going private. These costs included shareholder
       communications, accounting and legal fees (reflects savings based on the
       difference between current fees and expected fees for a private company
       of comparable size), investor relations and annual report costs.
 
    (d) Selling, General and Administrative
       The adjustment reflects: transaction based requirement to cover directors
       and officers of Andros Inc. for directors and officers
       insurance--$122,000; and severance and related payroll taxes to a former
       officer of Andros--$228,000.
 
(12) The Pro Forma Adjustments (Novametrix) reflect the assumed issuance of
    4,389,586 shares of Novametrix Common Stock to stockholders of Andros in
    exchange for all of the outstanding shares of Andros (4,389,586 multiplied
    by the Nasdaq closing price of $5.75 per share at July 26, 1996).

    adjusted based on completion of appropriate valuation studies.
 
(16) The Pro Forma Adjustments (Novametrix) reflect the write off of purchased
    in-process research and development.
 
(17) The Pro Forma Adjustments (Novametrix) reflect the increased amortization
    expense as a result of the increase in goodwill. Goodwill is amortized over

    Provisions reflects the assumed exercise of all outstanding options and
    warrants of Novametrix at July 28, 1996 and the resulting issuance of an
    additional 1,772,023 shares of Novametrix Common Stock pursuant to the
    Rights. The exercise of all Novametrix options and warrants will result in

    Stock pursuant to the Rights will result in additional goodwill of $10.0
    million and additional annual amortization of $0.4 million.

                                  INTRODUCTION
 
MEETING OF STOCKHOLDERS
 
    This Proxy Statement, which will be mailed commencing on or about October
23, 1996 to the persons entitled to receive the accompanying Notice of Annual
Meeting of Stockholders, is provided in connection with the solicitation of
Proxies on behalf of the Board of Directors of Novametrix for use at the Annual
Meeting of Stockholders to be held on November 25, 1996, and at any adjournment
or adjournments thereof, for the purposes set forth in such Notice. The
Company's executive offices are located at 56 Carpenter Lane, Wallingford,
Connecticut 06492.
 
PURPOSES OF THE MEETING
 
    At the Meeting, the Company's stockholders will consider and take action
upon (i) a proposal to approve, pursuant to the requirements of Nasdaq, the
issuance of the number of shares of Novametrix Common Stock contemplated by the
Merger Proposal; (ii) a proposal to approve the Company's 1996 Long Term
Incentive Plan; (iii) the election of two Class A directors of the Company for
the ensuing three years; (iv) a proposal to ratify the Novametrix Board's
selection of Ernst & Young LLP to serve as the Company's independent auditors
for the 1997 fiscal year; and (v) such other business as may properly come
before the Meeting or any adjournment or adjournments thereof.
 
VOTING REQUIREMENTS AT THE MEETING
 
    The presence, in person or by proxy, of the holders of a majority of the
voting power of all the outstanding shares of Novametrix Common Stock and Series
B Preferred Stock entitled to vote at the Meeting is necessary to constitute a
quorum at the Meeting or any adjournments thereof. Directors of the Company are
elected by a plurality vote. Approval and adoption of the Merger Proposal and
approval of other matters will require the affirmative vote of a majority of the
voting power of the shares present at the Meeting, in person or by proxy, and
entitled to vote on that proposal. Abstentions and broker non-votes will be
counted as present for the purpose of determining the presence of a quorum. For
the purpose of determining the vote required for approval of matters to be voted
on at the Meeting, shares held by stockholders who abstain from voting will be
treated as being "present" and "entitled to vote" on the matter and, thus, an
abstention has the same legal effect as a vote against the matter. However, in
the case of a broker non-vote or where a stockholder withholds authority from
his proxy to vote the proxy as to a particular matter, such shares will not be
treated as "present" and "entitled to vote" on the matter and, thus, a broker
non-vote or the withholding of a proxy's authority will have no effect on the
outcome of the vote on the matter.
 
    Holders of record of issued and outstanding shares of Novametrix Common
Stock and Series B Preferred Stock, in each case as of the Record Date, will be
entitled to notice of and to vote at the Meeting as described below. The Company
has no class or series of stock outstanding and entitled to vote at the Meeting
other than the Common Stock and the Series B Preferred Stock.
 
    As of the Record Date, there were 7,161,930 outstanding shares of Novametrix
Common Stock, each holder of which is entitled to one vote per share with
respect to each matter to be voted on at the Meeting, and 40,000 shares of
Series B Preferred Stock, the holder of which is entitled to 11 votes per share
with respect to each matter to be voted on at the Meeting. As of the Record
Date, the directors and executive officers of the Company beneficially owned
approximately 667,802 shares of Novametrix Common Stock (excluding 158,944
shares subject to exercisable options and warrants) and have advised Novametrix
that they intend to vote or direct the vote of all shares of Novametrix Common
Stock over which they have voting power for approval and adoption of the Merger
Proposal.
 
PROXIES
 
    All proxies that are properly executed by holders of Novametrix Common Stock
and received by Novametrix prior to the Meeting will be voted in accordance with
the instructions noted thereon. ANY
 
                                       19
<PAGE>
PROXY RECEIVED BY NOVAMETRIX THAT DOES NOT SPECIFY TO THE CONTRARY WILL BE VOTED
IN FAVOR OF THE MERGER PROPOSAL, IN FAVOR OF EACH OTHER PROPOSAL SET FORTH IN
SUCH PROXY AND PRESENTED TO THE STOCKHOLDERS OF NOVAMETRIX FOR APPROVAL AND IN
FAVOR OF NOVAMETRIX' NOMINEES FOR ELECTION AS DIRECTORS. Any holder of
Novametrix Common Stock who submits a proxy will have the right to revoke it, at
any time before it is voted, by filing with the Secretary of Novametrix written
notice of revocation or a duly executed later-dated proxy, or by attending the
Novametrix Meeting and voting such Novametrix Common Stock in person.
 
    All expenses of this solicitation, including the cost of preparing and
mailing this Proxy Statement, will be borne by Novametrix. In addition to use of
the mails, proxies may be solicited personally or by telephone or telegraph by
directors, officers and regular managerial employees of Novametrix, who will not
be specially compensated for such activities. Arrangements will be made with
custodians, nominees and fiduciaries for forwarding of proxy solicitation
materials to beneficial owners of shares held of record by such custodians,
nominees and fiduciaries for reasonable expenses incurred in connection
therewith. Novametrix has retained Georgeson & Company Inc. ("Georgeson") to
assist in its solicitation of proxies from brokers, nominees, institutions and
individuals. The Company's agreement with Georgeson provides for a one-time fee
of $20,000 plus $5.00 per call to individual stockholders, as well as
reimbursement of expenses incurred by Georgeson. Additional charges may be
incurred for consulting, reports or other additional services. Approximately 25
employees of Georgeson are involved in the Company's solicitation of proxies.
The Company estimates that the cost of preparing and mailing this Proxy
Statement and all other activities related to this solicitation, including fees
for attorneys, accountants and solicitors and printing, transportation and
mailing costs, will be approximately $375,000, of which $15,000 has been paid to
date.
 
    Under applicable regulations of the Commission, the Company and its
directors may be deemed to be "participants" in the Company's solicitation
efforts at the Meeting. For information on the directors of Novametrix, see
"Novametrix Management" and "Security Ownership of Certain Beneficial Owners and
Management of Novametrix".
 
    IT IS IMPORTANT THAT PROXIES BE RETURNED PROMPTLY. STOCKHOLDERS WHO DO NOT
EXPECT TO ATTEND THE MEETING IN PERSON ARE URGED TO MARK, SIGN AND DATE THE
ACCOMPANYING PROXY AND MAIL IT IN THE ENCLOSED RETURN ENVELOPE, WHICH REQUIRES
NO POSTAGE IF MAILED IN THE UNITED STATES, SO THAT THEIR VOTES CAN BE RECORDED.
 
PAUL COTE'S DISSIDENT 13D GROUP
 
    A group calling itself variously the "13D Shareholders Group," the "13D
Shareholders Group Regarding Novametrix Medical Systems Inc." and the
"Novametrix 13D Shareholders Group" is soliciting proxies to replace the two
Class A directors up for re-election this year with a lawyer named Paul Cote and
a dentist named Vartan Ghugasian. In addition, Paul Cote and his 13D Group are
soliciting proxies in support of a proposal to "maximize shareholder values."
 
    THE 13D GROUP, LED BY PAUL COTE AND HIS ADVISORS, IS A DISSIDENT STOCKHOLDER
GROUP WITH ABSOLUTELY NO AFFILIATION TO THE BOARD OF DIRECTORS OR MANAGEMENT OF
NOVAMETRIX.
 
    THE COTE GROUP'S NOMINEES.  The Cote Group's nominees have no experience in
the medical instrumentation business and have offered no concrete ideas on how
to increase Novametrix' stock price.
 
    THE COMPANY'S NOMINEES.  In contrast, the Company's nominees, Michael J.
Needham and Joseph A. Vincent, have been with Novametrix for 15 and 13 years,
respectively. Both bring valuable and relevant experience and knowledge to the
Novametrix Board and both support the Merger Proposal and the retention of
Tucker Anthony Incorporated as significant initiatives to increase stockholder
value. Mr. Needham owns 2,000 shares of Novametrix Common Stock and beneficially
owns an additional 25,588 shares issuable upon the exercise of currently
exercisable warrants. Mr. Vincent owns 50,716 shares of Novametrix Common Stock
and beneficially owns an additional 13,733 shares issuable upon the exercise of
currently exercisable stock options.

    Mr. Needham's business experience as Chairman and Chief Executive Officer of
SimEx Inc. has been invaluable to the Company, as have his insights into the
health care industry and finance gained while he was President of Helix
Investments Limited. Helix is a private venture capital fund co-founded by Mr.
Needham in 1968 and has a portfolio valued at $450,000,000. During Mr. Needham's
presidency, Helix made a number of investments in health care businesses in the
United States and Canada.
 
    Mr. Vincent has 22 years of diversified experience in the medical equipment
industry. He served as Controller of Novametrix for five years and was promoted
to his current position as Chief Financial Officer in April 1990. Prior to
joining Novametrix in 1983, Mr. Vincent was an Assistant Controller at Picker
International, Inc., a leader in the development of nuclear and ultrasound
medical diagnostic equipment. Mr. Vincent's detailed knowledge of Novametrix'
financial position and operations make him an invaluable member of the
Novametrix Board.
 
    The 13D Group has claimed that the reconfiguration of the Board of Directors
in May 1996 to equalize the number of directors in each of the three classes of
directors was contrary to the Certificate of Incorporation and By-laws of
Novametrix and the securities laws. In fact, one member of the Novametrix Board
was moved from one class to another in order to eliminate the unequal
distribution of directors among classes, which had resulted from prior director
resignations, so as to conform to the requirements of the Company's Certificate
of Incorporation, which calls for three classes of directors which are equal in
size.
 
    Prior to the reconfiguration of the Novametrix Board, there had been three
Class A directors, one Class B director and two Class C directors. The Company's
By-laws explicitly provide for increases and reductions in the size of the
Novametrix Board and the number of directors in each class in part in order to
provide the Board with the flexibility to respond to director resignations and
maintain three classes of directors of as nearly equal size as possible.
Therefore, on May 20, 1996, Steven J. Shulman, then a Class A director, resigned
and the Board of Directors elected him as a Class B director pursuant to the
Company's By-laws. The Class B directors will be elected at the 1997 Annual
Meeting.
 
    In addition, the Cote Group has made the claim that the Company's 1994 and
1995 Proxy Statements contained "promises" that the "three existing" Class A
directors would be "up for election" at the 1996 Annual Meeting. In fact, the
1994 and 1995 Proxy Statements made the general statement that "the Class A
directors will be elected at the 1996 Annual Meeting". This was merely a
statement as to when the CLASS of directors would next be elected. Mr. Cote
appears to have misread the statement as specific to the three Class A directors
in office at the time the 1994 and 1995 Proxy Statements were mailed. The
statement in the 1994 and 1995 Proxy Statements was correct and the requirements
of the Company's Certificate of Incorporation and By-laws have been met.
 
    This Board action, which was taken in accordance with the Company's By-laws
and applicable law, preceded any indication by the 13D Group that they were
considering nominating a slate of directors.
 
    PAUL COTE'S STOCKHOLDER PROPOSAL.  On April 5, 1996, the Company received a
proposal from Paul Cote to initiate a "program to maximize shareholder values".
On April 25, 1996, Paul Cote publicly disclosed the existence of a "13D Group"
consisting of himself, his wife and eight other stockholders, the stated purpose
of which was to support Paul Cote's proposal. Novametrix management's efforts to
arrive at a reasonable accommodation with Paul Cote have been repeatedly
rebuffed.
 
    THE NOVAMETRIX BOARD IS VERY MUCH IN FAVOR OF ENHANCING STOCKHOLDER VALUE
(AND, IN FACT, HAS RECOMMENDED THE MERGER IN ORDER TO INCREASE STOCKHOLDER
VALUE); IT UNANIMOUSLY OPPOSES THE COTE PROPOSAL BECAUSE THE PROPOSAL WOULD
UNNECESSARILY INTERFERE WITH THE NOVAMETRIX BOARD'S OBLIGATIONS TO MANAGE
NOVAMETRIX FOR THE BENEFIT OF ALL STOCKHOLDERS.
 
    The current Board of Directors has presided over a remarkable recovery by
the Company during the past five years, reducing debt from approximately $24
million to approximately $5 million and increasing stockholders' equity from
less than $100,000 to more than $12 million, while the stock price rose from
less than $1.00 per share to around $6.00 per share. A price of $6.00 per share
represents a price/earnings ratio of approximately 36 times earnings per share
for fiscal 1996 (calculated on a fully taxed basis) while the
 
                                       21
<PAGE>
average price/earnings ratio for companies in the medical device industry is 22
times earnings. As can be seen from the Performance Graph on page 85, Novametrix
Common Stock has out-performed its peer group and has generally equaled or
exceeded the broader market.
 
    In addition to ensuring that the Company is well managed and positioned to
experience substantial growth, at the direction of the Board of Directors,
management engaged the investment banking firm of Tucker Anthony Incorporated
five months ago with the purpose of enhancing stockholder value, including:
 
  -   Reviewing business plans, assessing strategies for growth and
      acquisitions, presenting financial options and assisting in the
      development and modeling of projections.
 
  -   Assisting the Company in the development of an overall financial strategy
      to address the Company's plans to increase and maximize the value of the
      Company.
 
  -   Assisting in the development of a plan to broaden investor awareness of
      the Company, which includes strategies to expand the number of market
      makers and institutional ownership.
 
    Tucker Anthony has since assisted the Company in its due diligence review of
Andros, assisted the Company in structuring and analyzing the fairness of the
Merger and issued a fairness opinion to the Board of Directors with respect to
the Merger. The Novametrix Board believes the Merger will substantially increase
stockholder value. For a detailed discussion of the reasons why the Board of
Directors believes that the Merger will benefit ALL Novametrix stockholders, see
"The Merger --Recommendation of the Board of Directors; Reasons for the Merger",
"--Opinion of Novametrix' Financial Advisor" and
"--Management and Operations of Novametrix Following the Merger".
 
    Members of the Company's management are meeting and communicating with
analysts, institutional investors and retail brokers in order to attract
additional institutional sponsorship and analyst coverage. The Novametrix Board
believes that the significantly larger size, critical mass and profitability of
the Company after the Merger, in addition to its expanded market capitalization,
will help further these goals.
 
    THE NOVAMETRIX BOARD UNANIMOUSLY RECOMMENDS THAT THE HOLDERS OF NOVAMETRIX
COMMON STOCK AND SERIES B PREFERRED STOCK VOTE AGAINST THE COTE GROUP'S NOMINEES
AND THEIR STOCKHOLDER PROPOSAL.
 
    STOCKHOLDERS ARE URGED NOT TO SIGN OR RETURN ANY OF THE GREEN PROXY CARDS
THEY RECEIVE FROM THE 13D GROUP UNTIL THEY HAVE REVIEWED AND CAREFULLY
CONSIDERED THE INFORMATION SET FORTH IN THIS PROXY STATEMENT.
 
    STOCKHOLDERS CAN REVOKE ANY PROXY THEY HAVE SENT TO THE 13D GROUP BY
SIGNING, DATING AND RETURNING THE COMPANY'S ENCLOSED WHITE PROXY CARD.

I. APPROVAL OF THE MERGER PROPOSAL
 
                                   THE MERGER
 
    The Effective Time, consideration and other terms of the Merger are
described in "The Merger Agreement" below.
 
BACKGROUND OF THE MERGER
 
    In early April 1996, Jean-Pierre L. Conte, a Principal of Genstar,
telephoned William J. Lacourciere, Chairman of the Board, President and Chief
Executive Officer of Novametrix, to schedule a meeting. On April 17, 1996, Mr.
Lacourciere and Mr. Conte met and discussed the businesses of Novametrix and
Andros and the possible benefits that could result from a combination of Andros
with Novametrix.
 
    In late April 1996, Novametrix and Andros agreed to exchange certain
confidential information to facilitate discussions regarding the terms of a
possible transaction, and Novametrix, Andros and Genstar executed a
confidentiality agreement dated May 10, 1996 whereby each party agreed to
maintain the confidential nature of certain information provided to it by the
other parties.
 
    At meetings held on May 21, 1996 and May 22, 1996 between senior management
of Novametrix and representatives of Genstar and Andros, Genstar and Andros made
presentations on their companies, after which a strategic alliance or
combination of Novametrix and Andros was discussed. Over the next several weeks,
Messrs. Lacourciere and Conte continued to have telephone conversations
regarding the possibility of a business combination.
 
    At a meeting on June 4, 1996, Mr. Lacourciere, Thomas M. Haythe, general
counsel and a director of the Company, Mr. Conte, and Richard Paterson, a
Managing Director of Genstar and Chairman of Andros, and other representatives
of Novametrix and Andros held extensive discussions regarding, among other
things, the complementary nature of the two businesses, revenue and cost savings
opportunities which would result from a combination and the framework of a
possible transaction.
 
    On June 5, 1996, Tucker Anthony was retained to act as financial advisor to
Novametrix in connection with the discussions with Andros and Genstar.
 
    On June 12, 1996, at a meeting at which Novametrix senior management, Mr.
Haythe, Mr. Conte, other Genstar representatives and representatives of Tucker
Anthony and the financial advisor to Andros, were present, the possible terms of
a business combination of Novametrix and Andros were reviewed in depth and
certain financial goals relating to the proposed combination were discussed,
including the basis for the exchange of Novametrix Common Stock for Andros
Common Stock.
 
    The Board of Directors of the Company held a regularly scheduled meeting on
June 17, 1996 at which it reviewed the year-end results of the Company. At that
meeting, Mr. Lacourciere disclosed the discussions being held with Genstar
regarding a possible business combination with Andros. After discussion of the
matter, the Novametrix Board resolved that the Company should proceed with
operational and legal due diligence reviews of Andros.
 
    On July 1 and 2, 1996, representatives of Haythe & Curley, counsel to
Novametrix, and Shearman & Sterling, counsel to Andros and Genstar, conducted
legal due diligence on Andros and Novametrix, respectively.
 
    Mr. Lacourciere, Joseph A. Vincent, Chief Financial Officer, Vice
President--Finance and Treasurer of Novametrix, and Philip F. Nuzzo, Vice
President--Medical Product Development and Marketing of Novametrix, together
with several other members of Novametrix' operations, engineering, accounting,
sales and administrative staffs and representatives of Tucker Anthony, conducted
an on-site due diligence review at Andros from July 8, 1996 through July 12,
1996. The review concentrated on Andros' technology, market share, market
opportunities and current contractual obligations and also included inspections
of Andros' California and Washington facilities. Andros and Genstar personnel
conducted similar due diligence reviews at Novametrix from July 16 through July
19, 1996.
 
                                       23
<PAGE>
    At a special meeting of the Board of Directors of Novametrix held on July
20, 1996, senior management of Novametrix and representatives of Tucker Anthony
presented and discussed the strategic aspects of the transaction. In addition,
an exchange ratio which would result in Andros stockholders receiving 47% of the
combined company's common stock was discussed. The Novametrix Board extensively
discussed the issues presented and the terms proposed. Upon consideration of the
foregoing, the Novametrix Board instructed senior management to engage in
further negotiations with Genstar and Andros to resolve certain open issues,
including reducing the percentage of the combined company's common stock to be
issued to Andros stockholders, and to report back to the Novametrix Board.
 
    At a special meeting of the Board of Directors of the Company held
telephonically on July 24, 1996 at which representatives of Tucker Anthony were
present, management updated the directors on the status of the negotiations,
including management's successful negotiation of a revised exchange ratio
pursuant to which Andros stockholders would receive 45% of the combined
company's common stock.
 
    On July 24 and 25, 1996 in New York, representatives of Haythe & Curley and
Shearman & Sterling continued negotiations which had begun in early July 1996
regarding the terms of the original Merger Agreement.
 
    On July 29, 1996, Novametrix' Board of Directors met again. Mr. Lacourciere
informed the Novametrix Board about the status of the negotiations with Genstar
and Andros and described any unresolved terms of the proposed business
combination and related transactions. The Novametrix Board had extensive
discussions with Novametrix' senior management and its legal advisors regarding
the issues presented and the terms proposed, which included the issuance of 45%
of the combined company's common stock to the Andros stockholders. Tucker
Anthony made a presentation of its financial analysis of the terms of the
transaction with Andros as originally proposed, at the conclusion of which
Tucker Anthony delivered its verbal opinion that, as of July 29, 1996, based
upon the procedures and subject to the assumptions described therein, the
original exchange ratio in the proposed Merger was fair to Novametrix and its
stockholders from a financial point of view. The Novametrix Board then
unanimously determined that the Merger as originally proposed was fair and in
the best interests of Novametrix and its stockholders and unanimously approved
the original Merger Agreement and the transactions contemplated by the original
Merger Agreement (subject to the resolution of minor open issues by the
Company's senior management and to the completion of appropriate documentation).
 
    Following the July 29, 1996 meeting of the Company's Board of Directors, the
parties and their respective advisors conducted further negotiations concerning
unresolved terms of the proposed Merger and related transactions. The original
Merger Agreement was then executed later that evening.
 
    The Board of Directors of the Company later received a written opinion from
Tucker Anthony confirming the verbal opinion they had delivered at the July 29,
1996 meeting.
 
    On October 10, 1996, Mr. Lacourciere, Mr. Vincent, representatives of
Genstar and Andros and representatives of Tucker Anthony met to review Andros'
operating results since the execution of the original Merger Agreement. The
participants extensively discussed the effects of unanticipated order delays at
Andros on Andros' operating and financial results. Novametrix and Tucker Anthony
analyzed the deferral of revenues resulting from the order delays.
 
    There followed numerous telephone conferences from October 10, 1996 through
October 16, 1996, in which Mr. Lacourciere, Mr. Vincent, Mr. Haythe, Mr. Conte,
Mr. Paterson and other representatives of Genstar discussed possible reductions
in the percentage of the outstanding shares of Novametrix Common Stock to be
issued in the Merger.
 
    On October 16, 1996, the senior management of Novametrix and Andros and
representatives of Genstar agreed to present the current revised terms of the
proposed Merger to the Boards of Directors of Novametrix and Andros.
 
    On October 18, 1996, representatives of Haythe & Curley and Shearman &
Sterling conducted negotiations regarding a draft amendment to the Merger
Agreement embodying the proposed revised terms of the Merger.
 
                                       24
<PAGE>
    On the evening of October 18, 1996, the Novametrix Board met to consider the
proposed amendment to the terms of the Merger Agreement. Novametrix' Board of
Directors, senior management and legal advisors reviewed and discussed the
proposed terms of the Merger and extensively discussed the reasons for the
revision in the terms. Representatives of Tucker Anthony presented their
financial analysis of the proposed transaction with Andros under the revised
terms and delivered Tucker Anthony's opinion that, as of October 18, 1996,
subject to the assumptions and based upon the procedures described in their
opinion, the amended exchange ratio in the proposed Merger was fair to
Novametrix and its stockholders from a financial point of view. After reviewing
Tucker Anthony's presentation and opinion, the Novametrix Board unanimously
determined that the Merger is fair and in the best interests of Novametrix and
its stockholders, unanimously approved the amendment to the Merger Agreement and
the transactions contemplated by the Merger Agreement, as so amended, and
unanimously resolved to recommend that the stockholders of Novametrix vote FOR
approval of the Merger Proposal.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS; REASONS FOR THE MERGER
 
    The Board of Directors of Novametrix has unanimously determined that the
Merger is fair to and in the best interests of Novametrix and its stockholders.
Accordingly, the Novametrix Board has unanimously recommended that the
stockholders of Novametrix vote FOR approval of the Merger Proposal.
 
    In reaching its conclusion to enter into the Merger Agreement and recommend
approval of the Merger Proposal by its stockholders, the Company's Board of
Directors considered a number of factors. The Novametrix Board believes that the
Merger represents a unique strategic opportunity for Novametrix to create a
worldwide leader in gas monitoring products. Because of the increase in size,
breadth of products and extent of distribution that the Company will possess
after the Merger, the Novametrix Board believes that Novametrix will be able to
realize significant increases in revenues and cost savings opportunities which
neither company would achieve independently. The two companies' complementary
technologies and the sharing of basic research and product development resources
should significantly increase Novametrix' ability to introduce new products to
the market quickly. The Novametrix Board also believes that the Merger will
significantly enhance the Company's ability to market its products to hospital
chains and OEMs in today's competitive health care environment.
 
    In addition, the Novametrix Board considered the following factors in
reaching its decision to recommend approval of the Merger Proposal:
 
        (i) The opportunity for Novametrix to expand its market presence by
    broadening its product lines and technology base in existing and
    complementary products areas; specifically, Novametrix will fill a key
    product offering in its existing product line through the acquisition of
    Andros' anesthetic agent products and technology;
 
        (ii) The ability of Novametrix to increase its revenues generated by the
    sales of its existing products and Andros' products through product
    enhancements based on overlapping technology of each entity;
 
       (iii) The ability of Novametrix to achieve greater critical mass in
    revenue size, breadth of products and operating resources and therefore
    compete more effectively in the healthcare environment and more effectively
    serve its customer base with a broader product offering;
 
        (iv) The ability of Novametrix to increase its customer base through
    greater penetration of the OEM market as a result of Andros' position as a
    supplier to certain significant OEM medical device suppliers such as
    Hewlett-Packard Co., Colin Medical Instruments Corporation and Draegerwerk;
 
        (v) The potential to accelerate product development and pursue
    additional product development opportunities as a result of the synergies
    between the technologies of the two companies and the combination of the two
    companies' research and development resources;
 
        (vi) Product and industry diversification within the field of gas
    monitoring as a result of Andros' presence in the automotive gas analyzer
    and environmental monitoring markets and the substantial market share held
    by Andros in the automotive gas analyzer industry segment;
 
                                       25
<PAGE>
       (vii) Recent developments at Andros including: (a) the development of the
    Microbench technology and its application to the automotive emissions
    products under development as well as the potential for future application
    to other products, (b) recent significant new medical customer contracts,
    including a contract with Siemens Medical Systems, Inc., (c) the
    opportunities for Andros' Scitec division arising out of new federal
    regulations requiring lead testing and (d) the recent streamlining of
    Andros' operations;
 
      (viii) The potential financial benefits to Novametrix stockholders,
    including (a) estimated pro forma per share accretion and (b) financial
    contribution to revenue, EBITDA, earnings before interest and taxes ("EBIT")
    per share and net income relative to the exchange ratio in the Merger;
 
        (ix) The implied aggregate equity consideration based on the exchange
    ratio in the Merger at recent market price levels of Novametrix Common Stock
    relative to the implied equity valuations of: (a) recent comparable
    transactions in the medical device and analytical instruments industries,
    (b) comparable publicly traded companies in the medical device and
    analytical instruments industries and (c) discounted cash flow operating
    results of Andros as a stand-alone company; the results of such analyses
    indicating that the implied cost of Andros at recent stock prices of
    Novametrix Common Stock was less than the implied equity value generated by
    such analyses and therefore favorable to Novametrix stockholders;
 
        (x) The potential cost savings synergies resulting from the Merger,
    including the elimination of duplicate corporate general and administrative
    services and functions, the consolidation of selected services such as sales
    and marketing, more efficient utilization of manufacturing capacity and
    economies of scale in purchasing raw materials and finished goods;
 
        (xi) Andros' demonstrated historical performance and projected future
    performance, including Andros' ability to generate strong cash flows to fund
    internal operations and development and to support a leveraged capital
    structure;
 
       (xii) The increased visibility of the Company within the financial
    community resulting from the Merger;
 
      (xiii) The presence of Genstar as a primary stockholder and its proven
    ability to enhance stockholder value through operating and manufacturing
    experience as well as corporate development expertise in the areas of
    mergers and acquisitions of selected companies, products and technologies;
 
       (xiv) The terms and conditions of the Merger and the Merger Agreement,
    including the amount and the form of the consideration, as well as the
    parties' mutual representations, warranties and covenants, and the
    conditions to their respective obligations;
 
       (xv) The terms of the Merger Agreement that permit Novametrix' directors,
    in the exercise of their fiduciary duties and subject to certain conditions,
    to respond to inquiries regarding potential business combination
    transactions, to provide information to, and negotiate with, third parties
    making an unsolicited proposal to acquire Novametrix in such a transaction
    and to terminate the Merger Agreement if Novametrix' Board of Directors
    determines to recommend an alternative business combination transaction. In
    that regard, Novametrix' Board of Directors noted that the Merger Agreement
    provides that if, under certain circumstances, the Merger Agreement is
    terminated, Novametrix will be obligated to pay to Andros a $3,000,000 fee.
    Novametrix' Board of Directors did not view the termination fee provision of
    the Merger Agreement as unreasonably impeding any interested third party
    from proposing a superior transaction. See "The Merger Agreement--
    Termination";
 
       (xvi) The expectation that the Merger will be accounted for as a
    purchase; and
 
      (xvii) The likelihood that the Merger will be consummated.
 
    The Novametrix Board also considered a number of potentially negative
factors in its deliberations concerning the Merger, including the following: (i)
the fact that the equityholders of Andros would own between 38% and 43% of the
outstanding voting power of Novametrix after the Merger and, as a result,
 
                                       26
<PAGE>
such equityholders, in concert with others, would gain substantial voting power
to elect Novametrix directors and otherwise determine the outcome of matters
submitted to a vote of Novametrix' stockholders, even prior to the January 1,
1999 expiration of the Voting Agreement; (ii) the risk that benefits sought to
be achieved in the Merger will not be achieved; (iii) the difficult challenges
posed by the integration of Andros' business operations with Novametrix' and the
increased time and resources required in management's integration effort,
including the difficulty in coordinating geographically separated organizations;
(iv) transaction costs, estimated to be $2,600,000, relating to the negotiation
of, preparation for and consummation of the Merger, and the necessity for the
Company to finance such costs through increased borrowings; and (v) Andros'
level of indebtedness and the associated risk in servicing such indebtedness.
 
    In view of the wide variety of factors considered in connection with its
evaluation of the terms of the Merger, the Company's Board of Directors did not
find it practicable to, and did not, quantify or otherwise attempt to assign
relative weights to the specific factors considered in reaching its
determination. Based on the factors described above, the Company's Board of
Directors has unanimously determined that the Merger is fair and in the best
interests of the Company and its stockholders, has unanimously approved the
Merger Agreement and the transactions contemplated by the Merger Agreement and
certain related matters and has unanimously resolved to recommend that the
stockholders of Novametrix vote FOR approval of the Merger Proposal.
 
    The Novametrix Board's unanimous determination that the Merger is fair to
and in the best interests of Novametrix and its stockholders, unanimous approval
of the Merger Agreement and the transactions contemplated by the Merger
Agreement (subject to the resolution of minor open issues by the Company's
senior management and to the completion of appropriate documentation) and
unanimous resolution to recommend that the stockholders of Novametrix vote FOR
approval of the Merger Proposal were made at a special meeting of the Board of
Directors of Novametrix held on October 18, 1996, at which all directors were
present either in person or telephonically. See "--Background of the Merger". As
described above under "--Background of the Merger", at meetings held on June 17,
July 20, July 24, July 29 and October 18, the Company's Board of Directors
received advice or presentations from, and reviewed the then-current proposed
terms of the Merger with, its management and its financial and legal advisors.
The presentation by Tucker Anthony at the meeting held on October 18, 1996 is
described below under "--Opinion of Novametrix' Financial Advisor". The
presentations by Haythe & Curley, Novametrix' legal advisors, described and
explained (i) the terms and conditions of the proposed Merger as set forth in
the drafts of the Merger Agreement, the Voting Agreement and the Registration
Rights Agreement and the results of such firm's legal due diligence review, and
(ii) the fiduciary duties applicable to the Company's Board of Directors in
evaluating the proposed transaction.
 
OPINION OF NOVAMETRIX' FINANCIAL ADVISOR
 
    Novametrix retained Tucker Anthony to act as its financial advisor in
connection with the Merger. Tucker Anthony was retained based on their
experience as a financial advisor in connection with mergers and acquisitions as
well as Tucker Anthony's industry knowledge and familiarity with Novametrix.
 
    At the October 18, 1996 special meeting of the Novametrix Board, Tucker
Anthony delivered its opinion to the effect that, as of such date and based on
the matters described therein, the exchange ratio in the Merger was fair to
Novametrix and its stockholders from a financial point of view. Tucker Anthony
did not recommend to Novametrix that any specific ratio constituted the
appropriate exchange ratio for the Merger. Tucker Anthony's opinion to the
Novametrix Board addresses only the fairness to Novametrix and its stockholders
from a financial point of view of the exchange ratio in the Merger, and does not
constitute a recommendation to any stockholder as to how such stockholder should
vote at the Novametrix Annual Meeting.
 
    THE COMPLETE TEXT OF THE OPINION DATED OCTOBER 18, 1996 IS ATTACHED HERETO
AS APPENDIX B AND THE SUMMARY OF THE OPINION SET FORTH BELOW IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION. STOCKHOLDERS OF
NOVAMETRIX ARE URGED TO READ SUCH OPINION CAREFULLY AND IN ITS ENTIRETY FOR A

<PAGE>
DESCRIPTION OF THE PROCEDURES FOLLOWED, THE FACTORS CONSIDERED, THE ASSUMPTIONS
MADE AND SCOPE OF THE REVIEW UNDERTAKEN BY TUCKER ANTHONY IN RENDERING ITS
OPINION.
 
    In connection with its opinion, Tucker Anthony reviewed, among other things,
the Merger Agreement dated July 29, 1996 and amended as of October 18, 1996 and
related documents, certain publicly available financial information for
Novametrix and Andros and reviewed financial information on Novametrix and
Andros furnished to them by both companies, including certain internal financial
analyses and forecasts prepared by Novametrix and Andros managements. Tucker
Anthony also held discussions with the management of Novametrix and Andros
concerning the businesses, past and current business operations, financial
condition and future prospects of both companies, independently and combined,
including certain information prepared jointly by the managements of Novametrix
and Andros concerning potential cost savings and synergies that could result
from the Merger. In addition, Tucker Anthony reviewed the stock price and
trading history of Novametrix; analyzed certain publicly available information
of companies it deemed comparable or otherwise relevant to its inquiry and
compared Novametrix and Andros from a financial point of view with these
companies; compared the financial terms of the Merger with other business
combinations which Tucker Anthony deemed comparable or otherwise relevant to its
inquiry; prepared a discounted cash flow analysis of Novametrix and Andros;
reviewed the contribution by each company to pro forma combined revenue, gross
profit, EBITDA, EBIT and net income; analyzed the pro forma earnings per share
of the combined company; discussed with senior management of Novametrix their
view of the strategic rationale for the Merger and the benefits of the Merger to
Novametrix; discussed with senior management of Novametrix and its counsel their
view of the likely outcomes of pending, threatened and possible claims against
Novametrix and Andros; and conducted such other financial studies and analysis
and reviewed such other information as it deemed relevant and appropriate.
 
    In its review and analysis and in arriving at its opinion, Tucker Anthony
assumed and relied upon the accuracy and completeness of all the financial
information publicly available or provided to Tucker Anthony by Novametrix and
Andros and did not attempt to verify any of such information. Tucker Anthony did
not make or obtain an independent evaluation or appraisals of any assets or
liabilities of Novametrix, Andros or any of its respective subsidiaries. Tucker
Anthony also relied upon, without independent certification, Novametrix'
management's assessment of the validity of Novametrix' and Andros' products and
technology. Tucker Anthony assumed (i) the financial projections of Novametrix
and Andros provided to Tucker Anthony have been reasonably prepared on a basis
reflecting the best currently available estimates and judgments of Novametrix
and Andros managements as to future financial performance and (ii) that such
projections will be realized in the amounts and time periods currently estimated
by the respective managements. Tucker Anthony also relied upon estimates and
judgments of Novametrix and Andros as to the future performance of both
companies, including the cost savings and synergies resulting from the Merger.
Tucker Anthony also relied upon Novametrix' management's assessment of the
likely outcomes of pending, threatened and possible claims against Novametrix
and Andros. Tucker Anthony also assumed, with the consent of Novametrix'
management, that the Merger will be accounted for as a purchase transaction
which will include a $22.7 million write-off of in-process research and
development and amortization periods for resulting goodwill of 25 years under
generally accepted accounting principles. Tucker Anthony's opinion is
necessarily based upon market, economic and other conditions that exist and can
be evaluated as of the date hereof.
 
    The following is a summary of the material financial analyses used by Tucker
Anthony in connection with providing their opinion, dated October 18, 1996, to
the Novametrix Board, which opinion is attached hereto as Appendix B. Tucker
Anthony also conducted such other financial studies and analyses and reviewed
such other information as it deemed relevant and appropriate to enable the
opinion to be rendered. In its review, Tucker Anthony also took into account an
assessment of general economic, market and financial conditions and certain
industry trends and related matters.
 
        (i) HISTORICAL STOCK TRADING ANALYSIS. Tucker Anthony reviewed the
    historical public trading prices and volume for the Novametrix Common Stock
    (y) on a daily basis from October 12, 1995 to October 16, 1996 and on a
    weekly basis from October 1, 1993 to October 14, 1996,
 
                                       28
<PAGE>
    and (z) in comparison to selected companies in the medical device industry
    including Criticare Systems Inc., Datascope Corp., Marquette Electronics
    Inc., Nellcor-Puritan Bennett Corp. and Protocol Systems Inc. (the "Medical
    Device Composite") and the S&P 500 Index, on a daily basis from October 3,
    1995 to October 16, 1996 and on a weekly basis from October 3, 1993 to
    October 14, 1996. Tucker Anthony noted that the price of Novametrix Common
    Stock had outperformed the index price of the Medical Device Composite at
    the end of the 52-week period ending October 14th.
 
        (ii) COMPARABLE COMPANIES ANALYSIS. Tucker Anthony reviewed and compared
    certain financial information relating to Novametrix and Andros to
    corresponding financial information, ratios and public market multiples for
    seven publicly traded corporations in the medical device industry:
    Novametrix, Criticare Systems Inc., Datascope Corp., Marquette Electronics
    Inc., Nellcor-Puritan Bennett Corp., Protocol Systems Inc. and SpaceLabs
    Medical Inc. (the "Selected Medical Device Companies") and four publicly
    traded corporations in the analytical instruments industry: CEM Corp.,
    Cyberoptics Corp., OI Corp. and TSI Inc. (the "Selected Analytical
    Instruments Companies") (collectively, the "Selected Companies"). The
    multiples of the Selected Companies were calculated using the closing prices
    of the common stock of such companies on October 16, 1996 (the "Reference
    Prices"). The multiples and ratios for the Selected Companies were based on
    publicly available information and composite analyst estimates. Tucker
    Anthony compared the selected multiples and ratios for the Selected
    Companies to those of Novametrix and Andros, based upon estimated future
    operating results provided by Novametrix management, the terms of the
    exchange ratio in the Merger and a price of Novametrix Common Stock of
    $5.625 (the closing market price of such stock on October 16, 1996).
 
        Tucker Anthony's analysis indicated that the mean Reference Prices to
    earnings per share ratio (the "P/E Ratio") for the Selected Medical Device
    Companies was estimated to be 17.1x in 1996 and 14.0x in 1997 and for the
    Selected Analytical Instruments Companies was estimated to be 12.9x in 1996
    and 8.2x in 1997. The estimated P/E Ratio for Novametrix was 26.8x in 1996
    and 19.4x in 1997 on a stand alone basis. The implied P/E Ratio based on the
    exchange ratio in the Merger is 13.7x for Andros on a stand alone basis in
    1996 and 15.4x in 1997. Tucker Anthony noted that the Selected Medical
    Device Companies and Novametrix multiples were higher than the comparable
    P/E Ratios for Andros implied by the exchange ratio in the Merger, and that
    the Selected Analytical Instruments Companies multiples were lower than
    those of Andros implied by the exchange ratio in the Merger.
 
        Tucker Anthony also analyzed estimated 1996 price to earnings multiples
    to the five year projected earnings per share growth rate (the "PEG Rate").
    The mean PEG Rate was 1.0x for the Selected Medical Device Companies and
    0.7x for the Selected Analytical Instruments Companies as compared to the
    PEG Rate of 1.4x for Novametrix on a stand alone basis and 0.4x for Andros
    on a stand alone basis. Tucker Anthony noted that the PEG Rates for the
    Selected Companies and Novametrix were higher than the PEG Rate for Andros
    implied by the exchange ratio in the Merger.
 
       (iii) COMPARABLE TRANSACTION ANALYSIS. Tucker Anthony analyzed certain
    public information relating to 15 selected transactions in the medical
    device industry (the "Selected Medical Device Transactions") and 15 selected
    transactions in the analytical instruments industry (the "Selected
    Analytical Instruments Transactions") (collectively, the "Selected
    Transactions") and compared such information to various multiples and ratios
    of the Merger, assuming estimated results of Andros for the year ending
    December 31, 1996, as provided by Novametrix management, the terms of the
    exchange ratio in the Merger and a price of Novametrix Common Stock of
    $5.625 (the closing market price of such stock on October 16, 1996). Tucker
    Anthony deemed the estimated results for the year ending December 31, 1996
    to be the most appropriate time period for comparison in this analysis due
    to the change of ownership, management and operating changes and capital
    structure and other factors which will have occurred in the year ending
    December 31, 1996 prior to the time of the Merger.
 
      Such analysis indicated that for the Selected Medical Device Transactions
    (x) aggregate consideration as a multiple of EBITDA ranged from 28.0x to
    6.0x, with a mean of 12.5x and a median of 10.8x as compared to a multiple
    of 7.1x for Andros on a stand alone basis in the Merger; (y) aggregate
 
                                       29
<PAGE>
    consideration as a multiple of EBIT ranged from 30.3x to 11.3x, with a mean
    of 18.8x and a median of 17.6x as compared to a multiple of 10.5x for Andros
    on a stand alone basis in the Merger; and (z) equity consideration as a
    multiple of the last twelve months ("LTM") net income ranged from 40.0x to
    5.4x, with a mean of 23.1x and a median of 23.2x as compared to a multiple
    of 13.7x for Andros on a stand alone basis in the Merger. Such analysis
    indicated that for the Selected Analytical Instruments Transactions (x)
    aggregate consideration as a multiple of EBITDA ranged from 9.9x to 2.9x,
    with a mean of 6.5x and a median of 6.7x as compared to a multiple of 7.1x
    for Andros on a stand alone basis in the Merger; (y) aggregate consideration
    as a multiple of EBIT ranged from 22.9x to 3.9x, with a mean of 11.7x and a
    median of 13.5x as compared to a multiple of 10.5x for Andros on a stand
    alone basis in the Merger; and (z) equity consideration as a multiple of LTM
    net income ranged from 40.0x to 6.3x, with a mean of 19.9x and a median of
    13.5x as compared to a multiple of 13.7x for Andros on a stand alone basis
    in the Merger. Tucker Anthony noted that, based on mean multiples of the
    Selected Transactions, the selected multiples exceeded the implied multiple
    of the Merger based on estimated 1996 results for Andros on a stand alone
    basis, with the exception of aggregate consideration as a multiple of EBITDA
    for the Selected Analytical Instruments Transactions.
 
       (iv) DISCOUNTED CASH FLOW. Tucker Anthony performed discounted cash flow
    analyses of Andros using Novametrix' management projections of Andros'
    future EBIT and cash flow available to its capital structure. In such
    analyses, Tucker Anthony assumed terminal value multiples of 6.5x to 8.0x
    fiscal 2000 EBITDA and discount rates of 10.0% to 14.0%. Such analyses
    produced implied equity values of Andros of $34.5 million to $59.8 million.
    Tucker Anthony noted that the implied equity value of the exchange ratio in
    the Merger based on a price of Novametrix Common Stock of $5.625 (the
    closing market price of such stock on October 16, 1996) was within this
    range. In addition, Tucker Anthony noted that the aforementioned valuation
    analyses were based on Andros as a stand-alone entity and did not include
    any of the potential cost savings or synergies that could result from the
    Merger.
 
        Tucker Anthony also performed discounted cash flow analyses of
    Novametrix based on management's projections of future EBIT and cash flow
    available to its capital structure. In such analyses, Tucker Anthony
    selected the following parameters: terminal value multiples of 7.0x to 8.5x
    fiscal 2000 EBITDA and discount rates of 12.0% to 16.0%. Such analyses
    implied equity values of Novametrix of $48.9 million to $63.4 million.
 
        Based on these discounted cash flow analyses, the implied exchange ratio
    ranged from 41.3% to 48.5% ownership of the combined entity for Andros.
    Tucker Anthony noted that this implied percentage is higher than the 38%
    equity percentage reflected in the exchange ratio in the Merger under the
    terms of the Merger.
 
        (v) PRO FORMA MERGER ANALYSIS. Tucker Anthony also analyzed the earnings
    per share of the combined companies based on the exchange ratio in the
    Merger. Using certain earnings estimates for Novametrix and Andros prepared
    by Novametrix management for the years 1996 through 2000, Tucker Anthony
    compared the earnings per share ("EPS") of Novametrix on a stand-alone
    basis, to the EPS of the common stock of the combined companies as
    forecasted by management of Novametrix on a pro forma basis. Tucker Anthony
    performed this analysis based on a price of $5.625 per share of Novametrix
    Common Stock (the closing market price of such stock on October 16, 1996).
    Such analyses indicated that the proposed transaction on an earnings per
    share basis in Novametrix' fiscal years 1997 through 1999 would be accretive
    in all such cases analyzed given the purchase accounting assumptions
    described herein.
 
        (vi) CONTRIBUTION ANALYSIS. Tucker Anthony reviewed certain estimated
    historical and future operating and financial information (including, among
    other things, revenue, gross profit, earnings before interest, tax and
    amortization, EBIT and net income) for Novametrix, Andros and the pro forma
    combined entity resulting from the Merger. Tucker Anthony analyzed the
    relative contribution of these income statement items by Novametrix and
    Andros to the combined companies on a pro forma basis without taking into
    account cost savings and synergies resulting from the Merger for estimated
    Novametrix fiscal years 1997 through 1998, based on financial data and
    estimates provided
 
                                       30
<PAGE>
    to Tucker Anthony by Novametrix management. In Novametrix fiscal years 1997
    through 1998, Novametrix would have contributed 42.1% and 40.7%,
    respectively, to combined total revenue, 48.5% and 50.8%, respectively, to
    combined gross profit, 30.0% and 32.9%, respectively, to combined earnings
    before interest, tax and amortization, 33.0% and 36.1%, respectively, to
    combined EBIT, and 55.5% and 57.4%, respectively, to combined net income.
    Tucker Anthony noted that, in the cases of revenue and income related
    percentages, such contributions by Novametrix were less than the 62% equity
    ownership retained by Novametrix as reflected in the exchange ratio in the
    Merger.
 
    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying Tucker Anthony's opinion. In arriving at its fairness determination,
Tucker Anthony considered the results of all such analyses. No company or
transaction used in the above analyses as a comparison is identical to
Novametrix or Andros or the contemplated transaction. The analyses were prepared
solely for purposes of Tucker Anthony providing its opinion to the Novametrix
Board as to the fairness to Novametrix of the exchange ratio pursuant to the
Merger Agreement and do not purport to be appraisals or necessarily reflect the
prices at which businesses or securities actually may be sold. Analyses based
upon future results are not necessarily indicative of actual future results and
are subject to industry performance, general business and economic conditions
and other matters.
 
    Tucker Anthony's opinion to the Novametrix Board was one of many factors
taken into consideration by the Novametrix Board in making its determination to
approve the Merger Agreement. The foregoing summary does not purport to be a
complete description of the analysis performed by Tucker Anthony and is
qualified by reference to the written opinion of Tucker Anthony set forth in
Appendix B hereto.
 
    Tucker Anthony, as part of its investment banking business, is regularly
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings and private placements and
for corporate and other purposes. Tucker Anthony has acted as Novametrix'
financial advisor in connection with, and has participated in the negotiations
leading to, the proposed Merger.
 
    Pursuant to a letter agreement dated June 25, 1996, Novametrix engaged
Tucker Anthony to act as the Company's exclusive financial advisor in connection
with a merger or other form of business combination involving the Company and
Andros. As compensation for its financial advisory services in connection with
the Merger, Tucker Anthony will receive a transaction fee (the "Transaction
Fee") from Novametrix equal to the lesser of 1.2% of the total consideration
paid or contributed for the stock of Andros (calculated at the Effective Time)
or $750,000 upon consummation of the Merger, provided, however, that the
Transaction Fee will not be less than $500,000. Tucker Anthony is entitled to
and has received a fee of $150,000 upon execution of the original Merger
Agreement and delivery of its fairness opinion. To date, Tucker Anthony has also
received $50,000 upon signature of the original Merger Agreement. The latter
fees will be credited against the Transaction Fee. Whether or not the Merger is
consummated, Novametrix has agreed to reimburse Tucker Anthony for reasonable
expenses incurred by Tucker Anthony, including legal fees and disbursements of
counsel. Novametrix has also agreed to indemnify Tucker Anthony and certain
related persons against certain liabilities to which Tucker Anthony may become
subject as a result of its engagement, including liabilities under the federal
securities laws.
 
    Separately, pursuant to a letter agreement dated June 18, 1996, Novametrix
engaged Tucker Anthony to act as its financial advisor for a minimum period of
three months in connection with the Company's strategic and financial planning.
To date, Tucker Anthony has received a $50,000 retainer pursuant to the June 18
letter agreement.
 
ACCOUNTING TREATMENT
 
    It is anticipated that the Merger will be accounted for by the Company as a
purchase in accordance with APB No. 16 "Business Combinations", as such term is
used under generally accepted accounting principles, for accounting and
financial reporting purposes. Under the purchase method of accounting, assets
and liabilities of Andros would be recorded at their fair value at the Effective
Time, with the excess
 
                                       31
<PAGE>
of the purchase price over the net tangible and identifiable intangible assets
acquired being recorded as goodwill.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
    Set forth below is a discussion of certain federal income tax consequences
under the Code to the Company and Andros as a result of the Merger. This
discussion does not address state, local or foreign income taxation.
 
    None of the parties to the Merger Agreement has requested a ruling from the
Internal Revenue Service with regard to the federal income tax consequences of
the Merger.
 
    Assuming the truth of the representations of the parties to the Merger
Agreement and their affiliates, the Merger will constitute a reorganization
under Section 368(a) of the Code. No gain or loss will be recognized by the
Company or Andros upon consummation of the Merger. The Company's tax basis in
the Andros Common Stock will generally be equal to the higher of (1) the
aggregate basis of Andros' former stockholders in the stock of Andros or (2) the
net basis to Andros of its assets. Andros' tax basis in its assets will be
unaffected by the Merger. As of April 28, 1996, the Company had net operating
loss carryforwards ("NOLs") for federal income tax reporting purposes of
approximately $12,875,000. Of this amount, $8,300,000 expires in 2005,
$4,200,000 expires in 2006 and $375,000 expires in 2007. Under Section 382 of
the Code and the Treasury Regulations promulgated thereunder, if a loss
corporation such as the Company has an "ownership change" within a designated
testing period, its ability to use its NOLs may be subject to an annual
limitation. Although the Company believes that consummation of the Merger will
not result in an ownership change for purposes of Section 382, there can be no
assurance that such an ownership change will not occur in the future. The
Company has no present intention, however, of issuing additional stock, options
or warrants which could result in an ownership change.
 
    THE DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY. THE
DISCUSSION IS BASED ON CURRENTLY EXISTING PROVISIONS OF THE CODE, EXISTING AND
PROPOSED TREASURY REGULATIONS THEREUNDER AND CURRENT ADMINISTRATIVE RULINGS AND
COURT DECISIONS. ALL OF THE FOREGOING ARE SUBJECT TO CHANGE AND ANY SUCH CHANGE
COULD AFFECT THE CONTINUING VALIDITY OF THIS DISCUSSION. NO INFORMATION IS
PROVIDED HEREIN WITH RESPECT TO THE TAX CONSEQUENCES, IF ANY, OF THE MERGER
UNDER APPLICABLE FOREIGN, STATE AND LOCAL LAWS.
 
MANAGEMENT AND OPERATIONS OF NOVAMETRIX FOLLOWING THE MERGER
 
    COMPOSITION OF THE NOVAMETRIX BOARD.  At the Effective Time, the Board of
Directors of the Company intends to increase the number of directors and appoint
new directors such that the Board of Directors of the Company will be comprised
of all of the members of the Company's Board of Directors at the Effective Time
or such smaller number of such members as may result from director resignations
effective at the Effective Time and an equal number of directors appointed by
the Board of Directors of Andros prior to the Effective Time, one of whom shall
be Richard D. Paterson. The Board of Directors of the Company intends to elect
Mr. Paterson as Chairman of the Board of the Company. The continuing members of
the Board of Directors of the Company and the members appointed by the Board of
Directors of Andros will be as equally distributed as possible among Class A,
Class B and Class C directors of the Company. At the Effective Time, each
committee of the Board of Directors of the Company will be composed of an equal
number of the continuing members of the Board of Directors of the Company and
the members appointed by the Board of Directors of Andros. For information
concerning the proposed appointees of Andros to the Board of Directors of the
Company, see "Novametrix Management--Executive Officers and Directors of
Novametrix".
 
                                       32
<PAGE>
    MANAGEMENT OF NOVAMETRIX.  Each of the executive officers of Novametrix is
expected to continue as an executive officer of Novametrix after the Merger.
Each of Novametrix' executive officers serves at the discretion of the
Novametrix Board.
 
    OPERATIONS OF NOVAMETRIX FOLLOWING THE MERGER.  THE FOLLOWING STATEMENTS IN
THIS PROXY STATEMENT ARE FORWARD-LOOKING STATEMENTS CONCERNING POST-MERGER
OPERATIONS OF NOVAMETRIX. THERE ARE MANY IMPORTANT FACTORS THAT COULD CAUSE
ACTUAL RESULTS TO DIFFER MATERIALLY FROM THOSE IN THE FORWARD-LOOKING STATEMENTS
HEREIN, INCLUDING, WITHOUT LIMITATION, DIFFICULTIES THAT MAY BE ENCOUNTERED IN
INTEGRATING THE OPERATIONS OF NOVAMETRIX AND ANDROS, WHICH DIFFICULTIES WILL BE
EXACERBATED BY THE NECESSITY OF COORDINATING GEOGRAPHICALLY SEPARATE
ORGANIZATIONS, FUNDAMENTAL CHANGES OCCURRING IN THE HEALTH CARE INDUSTRY AS A
RESULT OF ECONOMIC FORCES, REGULATORY INFLUENCES AND POLITICAL INITIATIVES, THE
CONTINUING TREND TOWARDS MORE STRINGENT REGULATORY OVERSIGHT OF MEDICAL DEVICE
MANUFACTURERS, UNCERTAINTIES RELATED TO PATENTS AND OTHER PROPRIETARY RIGHTS,
INTENSE COMPETITION IN THE INDUSTRIES IN WHICH NOVAMETRIX AND ANDROS OPERATE,
DIFFICULTIES IN DEVELOPING AND INTRODUCING NEW PRODUCTS AND THE INCREASING
FOREIGN SALES OF THE COMBINED COMPANY AND THE RESULTANT EXPOSURE TO FOREIGN
CURRENCY FLUCTUATIONS. MANY OF THESE IMPORTANT FACTORS ARE OUTSIDE NOVAMETRIX'
CONTROL AND COULD CAUSE THE FORWARD-LOOKING STATEMENTS TO BE MATERIALLY
INACCURATE, AND NO ASSURANCE CAN BE PROVIDED AS TO ANY FUTURE FINANCIAL RESULTS.
IN ADDITION, BECAUSE THE MARKETS IN WHICH NOVAMETRIX AND ANDROS OPERATE ARE
HIGHLY COMPETITIVE AND BECAUSE OF THE INHERENT UNCERTAINTIES ASSOCIATED WITH
MERGING TWO COMPANIES, NO ASSURANCE CAN BE PROVIDED THAT NOVAMETRIX WILL BE ABLE
TO REALIZE FULLY THE REVENUE AND COST SAVINGS OPPORTUNITIES THAT NOVAMETRIX
CURRENTLY EXPECTS AFTER THE MERGER OR THAT SUCH REVENUE SYNERGIES AND COST
SAVINGS WILL BE REALIZED AT THE TIMES CURRENTLY ANTICIPATED. FURTHER, NO
ASSURANCE CAN BE PROVIDED THAT COST SAVINGS THAT ARE REALIZED WILL NOT BE OFFSET
BY LOSSES IN REVENUES. NOVAMETRIX DOES NOT PRESENTLY INTEND TO UPDATE PUBLICLY
THE FOLLOWING FORECASTS OR PROVIDE SIMILAR FORECASTS IN THE FUTURE.
 
    The Novametrix Board believes that the Merger represents a unique strategic
and financial opportunity for Novametrix to create a worldwide leader in gas
monitoring products. Because of the resulting increase in size, breadth of
products and extent of distribution that the Company will possess after the
Merger, the Novametrix Board believes that Novametrix will be able to realize
significant revenue increases and cost savings which neither company would enjoy
on its own. The combined company would have sales of $66.8 million on a pro
forma basis for the fiscal year ended April 28, 1996, as compared to Novametrix'
stand-alone sales of $25.3 million for the same period. Management believes the
Merger to be a critical step towards further establishing the Company as a
primary supplier of medical devices to acute care providers and OEMs in today's
competitive health care environment.
 
    The management of Novametrix believes that the multiple synergies resulting
from the Merger will accelerate the potential growth of each company's business
beyond that which would be possible for each company on a stand alone basis.
After the Merger, Novametrix will serve most of the world's largest
manufacturers of medical monitoring equipment. The combined company would be the
world's largest OEM provider of NDIR gas analyzers for medical applications.
Substantially increased revenues should result from cross marketing each
company's products to the other company's OEM customers and through the
inclusion of Andros anesthetic agent technology in the Company's products sold
under the Novametrix brand name.
 
    The sale of Novametrix end-user products should also be enhanced through the
increased visibility provided by the greater critical mass of the combined
company. Virtually every domestic "national account" (i.e., large purchasers and
buying groups) purchases the products of one or more of the combined company's
OEM customers, providing access to such national account purchasers for the
Company's end-user products which is now unavailable to Novametrix. The Company
believes that a broader product line will enhance sales to the larger healthcare
providers such as hospital chains, whose purchasing patterns reflect the
nationwide trend toward buying from fewer vendors as the industry consolidates.
 
    Novametrix' sales and marketing staff will bring their medical monitoring
expertise to the management of the combined company's medical products while the
Andros staff will focus their historical expertise on the environmental and
automotive markets, providing better service to each and enhancing new sales
opportunities in both areas. This rationalization will create two stronger
dedicated sales forces.
 
                                       33
<PAGE>
    The Company anticipates continued growth in revenues from the Andros
automotive and environmental product lines for four main reasons. First, Andros
is introducing several new automotive and environmental products that are
expected to be well received by Andros' customers. Second, third world markets
for Andros' automotive products are expanding. Third, significant opportunities
for environmental products such as lead based paint testing and ambient air
monitoring are emerging in the U.S. market. Finally, the management of Andros
will focus on these core markets after the Merger, thus enhancing the Company's
sales efforts in these areas.
 
    Both companies specialize in NDIR technology, providing the unique
opportunity to combine the technical expertise of both companies and
facilitating the product development process. Also, both companies'
manufacturing processes are substantially the same, offering the opportunity to
gain economies in manufacturing and purchasing power. Additional cost savings
are expected to be derived through the elimination of duplicate corporate
general and administrative services and certain redundant senior management
positions.
 
    The Novametrix Board believes that revenues, cash flow and earnings should
increase substantially as a result of the Merger. Earnings per share of the
combined company should grow at a compound annual growth rate greater than 25%
over the next several years. For the fourth quarter of fiscal 1997, the Company
anticipates that revenue will more than double and earnings per share will
increase by approximately 50%, compared to Novametrix' fourth quarter of fiscal
1996. As a result of the higher levels of revenue, EBITDA, EBIT and net income
contributed by Andros and the strategic reasons for revenue enhancement together
with the potential cost savings discussed above, management believes the
combined company should approximately triple revenue and increase earnings per
share by approximately 100% in fiscal 1998, the first full fiscal year following
the Merger, compared to Novametrix' results as a stand-alone company in fiscal
1996. Management believes that the integration of the two companies will provide
substantial additional near term and future financial benefits beyond the
substantial increases in revenues, cash flow and earnings described above;
including sales productivity improvements, purchasing leverage, manufacturing
economies and a more effective and productive product development program.
 
LIQUIDITY AND SOURCES OF CAPITAL FOLLOWING THE MERGER
 
    After the Merger, Novametrix will continue to require sufficient liquidity
to source the combined company's working capital needs, primarily inventory,
accounts receivable and debt service. The combined company is expected to
generate sufficient cash from operations to cover the debt service requirements
on approximately $48 million of debt, and to have sufficient availability
against its revolving credit facility to satisfy its working capital needs.
Management has received proposals from two lenders to refinance Andros' $15
million of subordinated debt, with the expectation of reducing the current
interest rate of 13% to more typical senior lending rates of approximately 8% to
9%. This transaction would have a very favorable impact (approximately $600,000
to $750,000 per annum) on the Company's debt service requirements. Historically,
both Andros and Novametrix have provided significant EBITDA and cash from
operations which are expected to continue to be sufficient for the combined
company's cash requirements.
 
    In addition, after the Merger, Novametrix will continue to have
approximately $5.4 million of additional net proceeds that may be realized upon
the exercise of the Class A and Class B Warrants issued in June 1994, which are
redeemable by the Company under specified conditions. There are also additional
potential proceeds available from outstanding options and warrants in the
aggregate amount of $4.6 million as of September 30, 1996. Management believes
that EBITDA will be sufficient to meet the requirements of the combined company,
and that additional resources would be available on commercially reasonable
terms if needed.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    Contingent upon the consummation of the Merger, the Company and Genstar will
enter into the Voting Agreement pursuant to which, in any written consent or
meeting of stockholders of the Company
 
                                       34
<PAGE>
prior to January 1, 1999, Genstar and the purchasers or transferees of the
Genstar Shares will vote the Genstar Shares in favor of a Board of Directors of
the Company, at least one-half of whose members shall be nominated by a majority
of the current directors of the Company who continue to be directors of the
Company on (i) the date such consent is executed, (ii) the date that notice of
such meeting is mailed to stockholders of the Company or (iii) if no such notice
is mailed, the date of such meeting; provided that no more than two of such
nominees may be members of the management of the Company and that Genstar will
not be required under the Voting Agreement to vote in favor of a Board of
Directors of the Company less than half of whose members are nominees of
Genstar. Genstar Shares which are sold to the public pursuant to (i) an
effective registration statement under the Securities Act or (ii) the exemption
from registration provided by Rule 144 under the Securities Act thereupon cease
to be Genstar Shares. The above description is qualified in its entirety by the
copy of the Voting Agreement that is attached hereto as Appendix C and
incorporated herein by reference.
 
    As of September 27, 1996, Novametrix' directors and executive officers and
their affiliates beneficially owned approximately 9.1% (including shares subject
to exercisable options and warrants) of the outstanding voting securities of
Novametrix. For a discussion of the vote required for the approval of the Merger
by the holders of Novametrix Common Stock and Series B Preferred Stock, see
"Meeting of Stockholders" above.
 
    The Novametrix Board was aware of the foregoing interests and considered
them, among other matters, in approving and adopting the Merger Agreement and
the transaction contemplated thereby.
 
NO DISSENTERS' RIGHTS
 
    The holders of Novametrix Common Stock and Series B Preferred Stock are not
entitled to dissenters' appraisal rights in connection with, or as a result of,
the Merger.

    THE INFORMATION CONTAINED IN THIS PROXY STATEMENT WITH RESPECT TO THE MERGER

CAREFULLY.
 
EFFECTIVE TIME
 
    The Merger Agreement provides that the Merger will become effective upon the
last to occur of the filing of a certificate of merger with respect to the
Merger with the Secretary of State of the State of Delaware or at such later
time as is specified in the certificate of merger. The time at which the Merger
will become effective is referred to herein as the "Effective Time". Such
filing, together with all other filings or recordings required by the Delaware
General Corporation Law (the "Delaware Law") in connection with the Merger, will
be made as soon as practicable after the approval and adoption by the
stockholders of the Company of the Merger Proposal and the satisfaction or, to
the extent permitted under the Merger Agreement, waiver of all other conditions
to the Merger contained in the Merger Agreement.
 
THE MERGER
 
    At the Effective Time, Acquisition shall be merged into Andros, which shall
be the surviving corporation and a wholly owned subsidiary of the Company. The
corporate existence of Andros, with all its purposes, powers and objects, shall
continue unaffected and unimpaired by the Merger and as the surviving
corporation it shall be governed by the laws of the State of Delaware and
succeed to all of the rights, assets, liabilities and obligations of Acquisition
in accordance with the Delaware Law.
 
    CONSIDERATION TO BE RECEIVED IN THE MERGER.  At the Effective Time:
 
        (i)  ACQUISITION COMMON STOCK.  Each share of Acquisition Common Stock
    issued and outstanding immediately prior to the Effective Time shall, by
    virtue of the Merger and without any action on the part of the holder
    thereof, be converted into one share of Andros Common Stock.
 
        (ii)  ANDROS COMMON STOCK.  Each share of Andros Common Stock issued and
    outstanding immediately prior to the Effective Time, except for such shares
    held by Andros in its treasury or by the Company or any of its subsidiaries,
    shall, by virtue of the Merger and without any action on the part of the
    holder thereof, be converted into (a) the right to receive (i) that number
    (the "Exchange Number") of fully paid and nonassessable shares of Novametrix
    Common Stock equal to (x) .6129032 (the "Base Number") multiplied by the
    number of shares of Novametrix Common Stock outstanding immediately prior to
    the Effective Time (assuming conversion of all then outstanding shares of
    Series B Preferred Stock) divided by (y) the number of shares of Andros
    Common Stock outstanding immediately prior to the Effective Time (assuming
    the exercise in full of all then outstanding Andros Options and Andros
    Warrants), computed to four decimal places and (ii) under certain
    circumstances, additional shares of Novametrix Common Stock (see "--Earn-Out
    Shares" below) and (b) the Rights to receive additional shares of Novametrix
    Common Stock.
 
        (iii)  SECURITIES HELD BY THE COMPANY.  Each share, if any, of Andros
    Common Stock issued and outstanding immediately prior to the Effective Time
    which is then owned beneficially or of record by the Company or any
    subsidiary of the Company shall, by virtue of the Merger and without any
    action on the part of the holder thereof, be cancelled and retired and cease
    to exist, without any conversion thereof or payment therefor.
 
        (iv)  TREASURY SECURITIES.  Each share of Andros Common Stock held by
    Andros in its treasury immediately prior to the Effective Time shall, by
    virtue of the Merger, be cancelled and retired and cease to exist, without
    any conversion thereof or payment therefor.
 
                                       36
<PAGE>
    FRACTIONAL SHARES.  No fractional shares of Novametrix Common Stock will be
issued in the Merger. Each holder of Andros Common Stock who would have been
entitled upon consummation of the Merger to receive an aggregate number of
shares of Novametrix Common Stock comprising a fractional share, will be
entitled to receive, in lieu thereof, an amount in cash determined by
multiplying the average of the daily closing sale price per share of Novametrix
Common Stock on the Nasdaq for the ten trading days immediately prior to the
Effective Time by the fraction of a share of Novametrix Common Stock to which
such holder would otherwise have been entitled.
 
    STOCK OPTIONS AND WARRANTS.  At the Effective Time, each outstanding Andros
Option issued pursuant to the Stock Option Plan of Andros, whether vested or
unvested, shall be assumed by the Company. Each Andros Option shall be deemed to
constitute an option to acquire, on the same terms and conditions as were
applicable under such Andros Option, (i) (x) the same number of whole shares of
Novametrix Common Stock as the holder of such Andros Option would have been
entitled to receive pursuant to the Merger had such holder exercised such option
in full immediately prior to the Effective Time and (y) a number of Rights equal
to the number of Rights which the holder of such Andros Option would have been
entitled to receive pursuant to the Merger had such holder exercised such option
in full immediately prior to the Effective Time, (ii) at a price per share
(rounded up to the nearest whole cent) equal to (A) the aggregate exercise price
for the shares of Andros Common Stock otherwise purchasable pursuant to such
Andros Option divided by (B) the number of whole shares of Novametrix Common
Stock deemed purchasable pursuant to such Andros Option.
 
    At the Effective Time, each outstanding Andros Warrant shall be assumed by
the Company. Each Andros Warrant shall be deemed to constitute a warrant to
acquire, on the same terms and conditions as were applicable under such Andros
Warrant, (i) the same number of whole shares of Novametrix Common Stock as the
holder of such Andros Warrant would have been entitled to receive pursuant to
the Merger had such holder exercised such warrant in full immediately prior to
the Effective Time and (y) a number of Rights equal to the number of Rights
which the holder of such Andros Warrant would have been entitled to receive
pursuant to the Merger had such holder exercised such warrant in full
immediately prior to the Effective Time, (ii) at a price per share (rounded up
to the nearest whole cent) equal to (A) the aggregate exercise price for the
shares of Andros Common Stock otherwise purchasable pursuant to such Andros
Warrant divided by (B) the number of whole shares of Novametrix Common Stock
deemed purchasable pursuant to such Andros Warrant.
 
    LIMITED ANTIDILUTION RIGHTS.  At the Effective Time, the Company will issue
Rights to holders of record of Andros Common Stock as of the Effective Time in
accordance with the provisions of the Merger Agreement and to holders of Andros
Options and Andros Warrants who exercise such options or warrants after the
Effective Time in accordance with the provisions of the Merger Agreement. The
Rights shall not be transferable, except that Genstar may transfer Rights to its
general and limited partners upon receipt by the Company of (i) an opinion of
counsel to Genstar reasonably satisfactory to the Company to the effect that
such transfer will not violate the Securities Act or any state or foreign
securities laws and (ii) a representation letter from each such transferee in
form and substance reasonably satisfactory to the Company. The Rights will not
be evidenced by certificates. The Company will not issue fractional Rights.
 
    The Company has authorized the issuance of and will hold in reserve the
shares of Novametrix Common Stock issuable pursuant to the Rights (the
"Underlying Shares"), and monthly, on the first business day after the end of
each month in which an Antidilution Event (as defined below) shall have occurred
after the month in which the Effective Time shall have occurred (each such date,
an "Antidilution Date") (until and including the first business day of the month
immediately succeeding the later of the month in which the last of the remaining
warrants and options to acquire shares of Novametrix Common Stock outstanding
immediately prior to the Effective Time and Andros Options and Andros Warrants
have expired or been exercised), the Company will issue Underlying Shares to
Rights holders as set forth below with respect to any Antidilution Events which
shall have occurred during the immediately preceding month.
 
                                       37
<PAGE>
    Each Right grants to the holder thereof the right to receive from the
Company on each Antidilution Date a number of Underlying Shares equal to (x) the
sum of (i) the Base Number (or if there shall be an Adjusted Base Number (as
defined under "--Earn-Out Shares" below) in effect, the Adjusted Base Number)
multiplied by the number of shares of Novametrix Common Stock issued by the
Company pursuant to warrants or options to acquire shares of Novametrix Common
Stock outstanding immediately prior to the Effective Time (but excluding any
such shares issued upon conversion of the Series B Preferred Stock) and (ii) the
number of shares of Novametrix Common Stock which were issuable by Novametrix
upon the exercise of Andros Options or Andros Warrants (including Underlying
Shares so issuable as provided in the next succeeding paragraph), which Andros
Options or Andros Warrants were cancelled or otherwise expired unexercised, in
either case during the preceding month (or, in the case of the first
Antidilution Date after the issuance of such Right, after the Effective Time)
divided by (y) the number of Rights then outstanding or issuable upon the
exercise of all then outstanding Andros Options and Andros Warrants. The
issuance by the Company of Novametrix Common Stock pursuant to warrants or
options and the cancellation or expiration of Andros Options or Andros Warrants
as aforesaid are herein referred to as "Antidilution Events". Antidilution
Events will not include, and Rights shall not grant the holders thereof the
right to receive shares of Novametrix Common Stock in respect of, issuances at
or after the Effective Time of any Novametrix Securities (as defined in the
Merger Agreement) except for shares of Novametrix Common Stock issued pursuant
to options and warrants outstanding immediately prior to the Effective Time.
 
    Notwithstanding anything to the contrary contained in the Merger Agreement,
upon the occurrence of an Antidilution Event, the number of shares of Novametrix
Common Stock issuable upon the exercise of each then outstanding Andros Option
and Andros Warrant shall be increased by the number of Underlying Shares which
would have been issuable pursuant to the Rights subject to such Andros Option or
Andros Warrant (assuming such Rights were then outstanding).
 
    EARN-OUT SHARES.  Within ten business days after Novametrix receives its
audited consolidated financial statements (the date of such receipt is referred
to herein as the "Adjustment Date") for the fiscal year ending May 3, 1998
("Fiscal 1998"), if (i) the net revenues of the Andros business exceed
$48,900,000 for Fiscal 1998 or (ii) the combined company's consolidated EBITDA
exceeds $16,300,000 for Fiscal 1998, the Base Number would be increased to a
number (the "Adjusted Base Number") equal to a fraction (a) the numerator of
which is 38% plus the "Adjustment Factor" defined below and (b) the denominator
of which is 62% minus the Adjustment Factor, where the Adjustment Factor is
equal to 1% multiplied by the greater of (x) the quotient of (A) the amount by
which the net revenues of the Andros business for Fiscal 1998 exceed $48,900,000
divided by (B) $1,700,000 and (y) the quotient of (C) the amount by which the
EBITDA of the combined company for Fiscal 1998 exceeds $16,300,000 divided by
(D) $660,000, but in no event shall the Adjusted Base Number be greater than
 .7543860. The effects of any acquisitions of businesses (other than as a result
of the Merger) by Novametrix subsequent to July 29, 1996 would be eliminated in
computing such net revenues and EBITDA.
 
    On the Adjustment Date, if (i) the net revenues of the Andros business equal
or exceed $48,900,000 for Fiscal 1998 or (ii) the combined company's
consolidated EBITDA equals or exceeds $16,300,000 for Fiscal 1998, Novametrix
would issue additional shares of Common Stock (the "Earn-Out Shares") as
follows:
 
        (i) Novametrix would issue a number of Earn-Out Shares for each share of
    Andros Common Stock outstanding at the Effective Time to persons who held
    such shares at the Effective Time determined by subtracting (x) the Exchange
    Number determined by using the Base Number from (y) the Exchange Number
    determined by using the Adjusted Base Number.
 
        (ii) Novametrix would issue to each person who had exercised Andros
    Options or Andros Warrants prior to the Adjustment Date a number of Earn-Out
    Shares (rounded down to the nearest whole share) equal to the difference
    between (x) the number of shares of Novametrix Common Stock which would have
    been issued to such exercising holder had such Andros Option or Andros
    Warrant (or portion thereof), as applicable, been exercised after such
    Adjusted Base Number had been in
 
                                       38
<PAGE>
    effect and (y) the number of shares of Novametrix Common Stock actually
    issued upon the exercise of such Andros Option or Andros Warrant (or portion
    thereof), as applicable.
 
        (iii) If one or more Antidilution Events shall have occurred prior to
    the Adjustment Date, Novametrix would issue to each holder of Rights a
    number of Earn-Out Shares (rounded down to the nearest whole share) equal to
    the difference between (x) the number of shares of Novametrix Common Stock
    which would have been issued to such holder had the Adjusted Base Number
    been in effect with respect to all such Antidilution Events and (y) the
    number of shares of Novametrix Common Stock actually issued to such holder
    with respect to all such Antidilution Events.

business in the ordinary and usual course of business consistent with its prior

representatives full access to its and its subsidiaries' offices, properties,

and other information as such persons may reasonably request and instruct its
and its subsidiaries' employees, counsel and financial advisors to cooperate
with the other in its investigation.
 
COVENANTS--ANDROS
 
    ACQUISITION PROPOSALS FOR ANDROS.  Until the Effective Time or earlier
termination of the Merger Agreement, Andros and its subsidiaries and the
officers, directors, employees or other agents of Andros and its subsidiaries
will not, directly or indirectly, (i) take any action to solicit, initiate or
encourage any Andros Acquisition Proposal (as defined below) or (ii) engage in
negotiations with, or disclose any nonpublic information relating to Andros or
any of its subsidiaries or afford access to the properties, books
 
                                       40
<PAGE>
or records of Andros or any of its subsidiaries to, any person that may be
considering making, or has made, an Andros Acquisition Proposal. Andros will
promptly notify Novametrix after receipt of any Andros Acquisition Proposal or
any indication that any person is considering making an Andros Acquisition
Proposal or any request for nonpublic information relating to Andros or any of
its subsidiaries or for access to the properties, books or records of Andros or
any of its subsidiaries by any person that may be considering making, or has
made, an Andros Acquisition Proposal. For purposes hereof, "Andros Acquisition
Proposal" means any offer or proposal for, or any indication of interest in, a
merger or other business combination involving Andros or any of its subsidiaries
or the acquisition of any equity interest in, or a substantial portion of the
assets of, Andros or any of its subsidiaries, other than the transactions
contemplated by the Merger Agreement.
 
    CERTAIN AGREEMENTS WITH AFFILIATES AND OTHERS.  To ensure that the issuance
of Novametrix Common Stock in the Merger complies with the Securities Act, prior
to the Effective Time, Andros will cause to be delivered to Novametrix a list
identifying each person who might immediately prior to the Effective Time be
deemed to be an "affiliate" of Andros for purposes of Rule 145 under the
Securities Act (each, a "Securities Act Affiliate"). Andros shall use its best
efforts to obtain from each person who is identified as a possible Securities
Act Affiliate prior to the Effective Time an agreement providing that such
person will not offer to sell, sell or otherwise dispose of any Novametrix
Common Stock issued to such person in the Merger in violation of the Securities
Act.
 
COVENANTS--NOVAMETRIX
 
    ACQUISITION PROPOSALS FOR NOVAMETRIX.  Until the Effective Time or earlier
termination of the Merger Agreement, Novametrix and its subsidiaries and the
officers, directors, employees or other agents of Novametrix and its
subsidiaries will not, directly or indirectly, (i) take any action to solicit,
initiate or encourage any Novametrix Acquisition Proposal (as defined below) or
(ii) engage in negotiations with, or disclose any nonpublic information relating
to Novametrix or any of its subsidiaries or afford access to the properties,
books or records of Novametrix or any of its subsidiaries to, any person that
may be considering making, or has made, a Novametrix Acquisition Proposal.
Provided that the Board of Directors of Novametrix, after receiving an opinion
of outside counsel to the effect that the Novametrix Board is required to do so
in order to discharge properly its fiduciary duties, may consider, negotiate,
approve and recommend to the stockholders of Novametrix an unsolicited bona fide
written Novametrix Acquisition Proposal which the Novametrix Board determines in
good faith (after consultation with its financial advisors) is made by a person
financially capable of consummating such Novametrix Acquisition Proposal (any
such Novametrix Acquisition Proposal being referred to herein as a "Superior
Novametrix Proposal"). For purposes hereof, "Novametrix Acquisition Proposal"
means any offer or proposal for, or any indication of interest in, a merger or
other business combination involving Novametrix or any of its subsidiaries or
the acquisition of any equity interest in, or a substantial portion of the
assets of, Novametrix or any of its subsidiaries, other than the transactions
contemplated by the Merger Agreement.
 
    Novametrix has agreed to notify Andros promptly after receipt of any
Novametrix Acquisition Proposal or any indication that any person is considering
making a Novametrix Acquisition Proposal or any request for nonpublic
information relating to Novametrix or any of its subsidiaries or for access to
the properties, books or records of Novametrix or any of its subsidiaries by any
person that may be considering making, or has made, a Novametrix Acquisition
Proposal.
 
    If the Board of Directors of Novametrix receives a request for material
nonpublic information by a party who makes a Superior Novametrix Proposal, then,
and only in such case, Novametrix may, subject to the execution of a
confidentiality agreement substantially similar to that then in effect between
Andros and Novametrix, provide such party with access to information regarding
Novametrix. Novametrix agrees not to release any third party from any
confidentiality or standstill agreement to which Novametrix is a party.
 
    ACQUISITION.  Novametrix has agreed to take all action necessary to cause
Acquisition to perform its obligations under the Merger Agreement and to
consummate the Merger on the terms and conditions set forth in the Merger
Agreement.
 
                                       41
<PAGE>
    INDEMNIFICATION OF ANDROS OFFICERS AND DIRECTORS.  Novametrix has also
agreed that, from and after the Effective Time, Novametrix and Andros will each
indemnify, defend and hold harmless, to the fullest extent permitted by law, the
present and former officers and directors of Andros and its subsidiaries against
all losses, claims, damages and liability in respect of acts or omissions
occurring at or prior to the Effective Time. Novametrix will cause Andros (and
its successors) to establish and maintain provisions in its certificate of
incorporation and by-laws concerning the indemnification and exoneration of
Andros' former and present officers, directors, employees and agents that are no
less favorable to those persons than the provisions of Andros' certificate of
incorporation and by-laws in effect on the date of the Merger Agreement.
 
    INCLUSION IN NASDAQ NATIONAL MARKET.  Novametrix will use its reasonable
best efforts to cause the shares of Novametrix Common Stock to be issued in the
Merger (including the Underlying Shares) to be approved for inclusion in the
Nasdaq subject to official notice of issuance, prior to the Effective Time.
 
AMENDMENT
 
    Any provision of the Merger Agreement may be amended or supplemented at any
time by written agreement of the Company, Acquisition and Andros; provided,
that, the amount and kind of consideration to be received by the holders of
Andros Common Stock as part of the Merger and the terms of the Andros
Certificate of Incorporation may not be altered or changed in any manner, and
the terms of the Merger Agreement may not be altered or changed if such
alteration or change would adversely affect the holders of any shares of capital
stock of Andros after approval and adoption of the Merger Agreement by such
holders, without the further approval of such holders and each party's Board of
Directors.
 
TERMINATION
 
    The Merger Agreement may be terminated and the Merger may be abandoned at
any time prior to the Effective Time (notwithstanding any approval of the Merger
Agreement by the stockholders of Andros or the Company): (i) by mutual written
consent of Andros and the Company; (ii) by either Andros or the Company, if the
Merger is not consummated by March 31, 1997 (provided that the right to
terminate the Merger Agreement at such date will not be available to any party
whose failure to fulfill any of its obligations under the Merger Agreement is
the cause of or results in the failure to consummate the Merger by such date);
(iii) by either Andros or the Company, if any applicable domestic law, rule or
regulation makes consummation of the Merger illegal or otherwise prohibited or
if any judgment, injunction, order or decree of a court of competent
jurisdiction restrains or prohibits the consummation of the Merger, and such
judgment, injunction, order or decree becomes final and nonappealable; (iv) by
either Andros or the Company, if stockholder approval of the Merger Proposal by
the stockholders of the Company is not obtained by reason of the failure to
obtain the requisite vote upon a vote at a duly held meeting of stockholders or
at any adjournment thereof; (v) by Andros, if the Board of Directors of the
Company or any committee thereof with the power to do so withdraws or modifies
in a manner adverse to Andros its approval or recommendation of the Merger
Agreement, the Merger or any other transaction contemplated by the Merger
Agreement or recommends, takes a neutral position with respect to, is unable to
take a position with respect to or fails to reject another merger, consolidation
or business combination with, or acquisition of, the Company or its assets or
another tender or exchange offer for shares of Novametrix Common Stock, or
resolves to do any of the foregoing; (vi) by either Andros or the Company (the
"Terminating Party"), if (x) there is a breach by the other party of any
representation or warranty contained in the Merger Agreement which would have or
would be reasonably likely to have a Material Adverse Effect upon the Company or
Andros and their respective subsidiaries taken as a whole, as the case may be,
or (y) there is a material breach of any of the covenants or agreements set
forth in the Merger Agreement on the part of the other party, which breach is
not curable or, if curable, is not cured within 30 days after written notice of
such breach is given by the Terminating Party to the other party; or (vii) by
Andros, if it is disclosed or Andros otherwise learns that ownership of an
aggregate of 50% or more of the then outstanding shares of Novametrix Common
Stock has been acquired by any person and such person's affiliates, other than
Genstar or its affiliates.

    If the Merger Agreement is terminated pursuant to the above provisions it
will become void and of no effect with no liability on the part of any party
thereto, except for certain payment provisions described below and certain
agreements with respect to confidential information and except that a party will
remain liable for any willful breaches of the Merger Agreement.

    Pursuant to the Merger Agreement, Andros is obligated to pay the Company a
fee of $3,000,000, plus actual, documented out-of-pocket expenses of the Company
and its affiliates relating to the transactions contemplated by the Merger
Agreement (including, but not limited to, reasonable fees and expenses payable
to the Company's counsel, accountants, financial advisors, consultants, banks,
other financial institutions and other persons and their respective agents and
counsel), upon termination of the Merger Agreement by the Company due to a
breach by Andros of its covenant in the Merger Agreement that it will not,
directly or indirectly, (i) take any action to solicit, initiate or encourage
any Andros Acquisition Proposal or (ii) engage in negotiations with, or disclose
any nonpublic information relating to Andros or any of its subsidiaries or
afford access to the properties, books or records of Andros or any of its
subsidiaries to, any person that may be considering making, or has made, an

    Pursuant to the Merger Agreement, the Company is obligated to pay Andros a
fee of $3,000,000, plus actual, documented out-of-pocket expenses of Andros and
its affiliates relating to the transactions contemplated by the Merger Agreement
(including, but not limited to, reasonable fees and expenses payable to Andros'
counsel, accountants, financial advisors, consultants, banks, other financial
institutions and other persons and their respective agents and counsel), upon
the earliest to occur of the following events: (i) the Merger Agreement is
terminated by Andros because (x) the Board of Directors of the Company or any
committee thereof with the power to do so withdraws or modifies in a manner
adverse to Andros its approval or recommendation of the Merger Agreement, the
Merger or any other transaction contemplated by the Merger Agreement or
recommends, takes a neutral position with respect to, is unable to take a
position with respect to or fails to reject another merger, consolidation or
business combination with, or acquisition of, the Company or its assets or
another tender or exchange offer for shares of Novametrix Common Stock, or
resolves to do any of the foregoing or (y) it shall have been disclosed or
Andros shall have otherwise learned that ownership of an aggregate of 50% or
more of the then outstanding shares of Novametrix Common Stock has been acquired
by any person and such person's affiliates, other than Genstar or its
affiliates, (ii) the Merger Agreement is terminated by Andros due to a breach by

any nonpublic information relating to the Company or any of its subsidiaries or
afford access to the properties, books or records of the Company or any of its
subsidiaries to, any person that may be considering making, or has made, a
Novametrix Acquisition Proposal; provided that nothing shall prevent the Board
of Directors of the Company, after receiving an opinion of outside counsel to
the effect that the Novametrix Board is required to do so in order to discharge
properly its fiduciary duties, from considering, negotiating, approving and
recommending to the stockholders of the Company an unsolicited bona fide written
Novametrix Acquisition Proposal which the Novametrix Board determines in good
faith (after consultation with its financial advisors) is made by a person
financially capable of consummating such Novametrix Acquisition Proposal or
(iii) the Merger Agreement is terminated by Andros or the Company as a result of
a failure to obtain the requisite approval of the Company's stockholders if at
the time of the taking of the vote for such approval, or any adjournment
thereof, there shall have been publicly announced, and not withdrawn, a proxy
contest, tender offer, exchange offer, merger or other Novametrix Acquisition
Proposal (the "Pre-Termination Transaction"), and, within 12 months of such
vote, the Company shall enter into, or be the subject of, a transaction which
would qualify as a transaction under the definition of "Novametrix Acquisition
Proposal" or any transaction wherein a person or group of persons acquires 50%
or more of the outstanding voting securities of the Company (inclusive of voting
rights contingent on conversion), in any such case with the same persons, or
affiliates of the persons, who shall have proposed the Pre-Termination
Transaction.

    Except as set forth above, all costs and expenses incurred in connection
with the Merger Agreement are to be paid by the party incurring such cost or
expense.
 
OTHER AGREEMENTS
 
    Contingent upon the consummation of the Merger, the Company and Genstar will
enter into the Voting Agreement pursuant to which, in any written consent or
meeting of stockholders of the Company prior to January 1, 1999, Genstar and the
purchasers or transferees of Genstar Shares will vote the Genstar Shares in
favor of a Board of Directors of the Company, at least one-half of whose members
shall be nominated by a majority of the current directors of the Company who
continue to be directors of the Company on (i) the date such consent is
executed, (ii) the date that notice of such meeting is mailed to stockholders of
the Company or (iii) if no such notice is mailed, the date of such meeting;
provided that no more than two of such nominees may be members of the management
of the Company and that Genstar will not be required under the Voting Agreement
to vote in favor of a Board of Directors of the Company less than half of whose
members are nominees of Genstar. Genstar Shares which are sold to the public
pursuant to (i) an effective registration statement under the Securities Act or
(ii) the exemption from registration provided by Rule 144 under the Securities
Act thereupon cease to be Genstar Shares. The above description is qualified in
its entirety by the copy of the Voting Agreement that is attached hereto as
Appendix C and incorporated herein by reference.
 
    Contingent upon the consummation of the Merger, at the Effective Time, the
Company and the holders of securities of Andros immediately prior to the
Effective Time (the "Andros Stockholders") will enter into a Registration Rights
Agreement. Pursuant to such agreement, beginning nine months after the Effective
Time, at any time and from time to time, the Company will be obligated to use
its reasonable best efforts to cause to be registered under the Securities Act
the sale of any or all shares of Novametrix Common Stock (including the
Underlying Shares) issued in the Merger (as appropriately adjusted) and
beneficially owned by the Andros Stockholders immediately after the Effective
Time (such shares, the "Original Shares") upon the request of the Stockholder
Representative (as defined in the Registration Rights Agreement). The Company
shall not be obligated to file and cause to become effective more than two
registration statements in which shares of Novametrix Common Stock are
registered pursuant to the above demand rights, there shall be at least a
six-month period between such filings and each such demand must cover at least a
number of shares of Novametrix Common Stock equal to 20% of the number of the
Original Shares. Such demand registration rights terminate upon the first to
occur of the tenth anniversary of the Registration Rights Agreement or the date
on which at least 80% of the aggregate number of Original Shares and Underlying
Shares shall have been registered under the Securities Act. Additionally, the
Company will be obligated, subject to certain restrictions, to use its
reasonable best efforts to include in any registration of Novametrix Common
Stock (other than pursuant to a registration statement on Form S-4 or S-8)
effected by the Company additional Original Shares, as requested by the Andros
Stockholders (a "supplemental registration"). The Company will be obligated to
pay all expenses relating to both demand registrations and all supplemental
registrations, except that legal fees and expenses of counsel to Genstar or its
permitted transferees shall not be payable by the Company after the first two
supplemental registrations effected by it. The above description is qualified in
its entirety by the copy of the Registration Rights Agreement that is attached
hereto as Appendix D and incorporated by reference herein.

                    PRO FORMA COMBINED FINANCIAL INFORMATION
 
    The following unaudited Pro Forma Consolidated Condensed Balance Sheet as of
July 28, 1996 gives effect to the Merger assuming it had occurred at that date.
The unaudited Pro Forma Consolidated Condensed Statements of Operations for the
three month period ended July 28, 1996 (Andros for the three months ended July
31, 1996) and the year ended April 28, 1996 give effect to the Merger as if it
had occurred as of May 1, 1995. The pro forma information assumes the Merger
will be accounted for under the purchase method of accounting and includes the
effects of the assumptions and adjustments described in the accompanying notes
to the pro forma consolidated condensed financial statements. The pro forma
adjustments which give effect to the Merger are referred to as Pro Forma
Adjustments (Novametrix).
 
    Additionally, the unaudited Pro Forma Consolidated Condensed Statements of
Operations for the three month period ended July 28, 1996 and the year ended
April 28, 1996 give effect to the acquisitions of common shares of Andros Inc.
by Andros, which occurred between March 26, 1996 and May 14, 1996, as if such
acquisitions had occurred as of May 1, 1995. The pro forma information gives
effect to these transactions under the purchase method of accounting and to the
assumptions and adjustments described in the accompanying notes to the pro forma
consolidated condensed financial statements. The pro forma adjustments which
give effect to the acquisition of Andros Inc. by Andros are referred to as Pro
Forma Adjustments (Andros).
 
    The pro forma combined financial information should be read in conjunction
with the historical audited and unaudited financial statements and related notes
thereto of Novametrix, Andros and Andros Inc. included elsewhere in this Proxy
Statement or incorporated herein by reference. These pro forma statements are
presented for informational purposes only and are not necessarily indicative of
the results that actually would have occurred had the pro forma transactions
been consummated at the dates indicated, nor are they necessarily indicative of
the future operating results or financial position of Novametrix. In addition,
they are not intended to be a projection of future results and do not include
any synergies that might be achieved from combining the operations of the two
companies. Permitted pro forma adjustments include only the effects of events
directly attributable to a transaction that are factually supportable and
expected to have a continuing impact. Pro forma adjustments reflecting
anticipated "efficiencies" in operations resulting from a transaction are, under
most circumstances, not permitted. As a result of the limitations imposed with
regard to the types of permitted pro forma adjustments, management believes that
this unaudited pro forma information is not indicative of future results of
operations.

(a) Reflects $9.4 million of charges and costs incurred by Andros Inc. in
    conjunction with, but not directly related to, the acquisition. These
    charges and costs relate to accounts receivable, inventories, product
    warranty, property taxes and other liabilities. Charges of $5.0 million,
    $0.4 million and $4.0 million are included in cost of products sold,
    research and product development and selling, general and administrative.

(1) Under the Merger Agreement, Novametrix will issue to the stockholders of
    Andros shares of Novametrix Common Stock constituting 38% of the combined
    company at the Effective Time of the Merger. After the end of Novametrix'
    fiscal year ending May 3, 1998, additional shares of Novametrix Common Stock
    constituting up to 5% of the Company may be issued, and reserved for
    issuance to option and warrant holders of Andros, based upon Andros' net
    revenues or the combined company's consolidated EBITDA. In addition,
    Novametrix will issue to the stockholders of Andros anti-dilution Rights
    enabling the holders to maintain, without additional payment, their
    percentage ownership level as Novametrix options and warrants outstanding at
    the Effective Time of the Merger are exercised. The Pro Forma Consolidated
    Condensed Balance Sheet reflects the assumed issuance of 4,389,589 shares of
    Novametrix Common Stock (based on the outstanding shares of Novametrix at
    July 28, 1996) in exchange for all outstanding shares of Andros Common
    Stock. The number of shares of Novametrix Common Stock to be issued is based
    upon the exchange ratio of 48.8818 shares of Novametrix Common Stock for
    each share of Andros Common Stock. The actual number of shares of Novametrix
    Common Stock to be issued in the Merger will be determined at the Effective
    Time of the Merger. The market value of a share of Novametrix Common Stock
    is assumed to be $5.75 per share (the Nasdaq closing price per share at July
    26, 1996).
 
(2) Earnings per share for the period and the year presented are based on the
    weighted-average number of shares of Novametrix Common Stock and dilutive
    common stock equivalents outstanding during the year. Common stock
    equivalents consist of Series B Preferred Stock, stock options, warrants and
    shares subscribed under the Stock Purchase Plan. The weighted average shares
    presented on both the Pro Forma Consolidated and Pro Forma Consolidated
    Assuming Anti-Dilution Provisions information includes all shares which are
    contingently issuable pursuant to the Rights and the outstanding warrants of
    Andros which will be converted to Novametrix warrants.
 
(3) The Pro Forma Consolidated Condensed Balance Sheet as of July 28, 1996
    reflects Andros' balances as of July 31, 1996. The Pro Forma Consolidated
    Statement of Operations for the three month period ended July 28, 1996
    reflects Novametrix' results of operations for the three month period ended
    July 28, 1996 and Andros' results of operations for the three month period
    ended July 31, 1996. The Pro Forma Consolidated Statement of Operations for
    the year ended April 28, 1996 reflects Novametrix' results of operations for
    its fiscal year ended April 28, 1996 and the results of operations for
    Andros Inc. and Andros for the year ended April 30, 1996.
 
(4) Genstar created Andros expressly for the purpose of acquiring Andros Inc., a
    public company traded on the Nasdaq. On March 26, 1996, Andros Acquisition
    closed the Tender Offer for all of the shares of Andros Inc. for $18.00 per
    share. As a result of the Tender Offer, Andros Acquisition acquired
    approximately 58% of the outstanding shares of Andros Inc. At this time
    Andros initiated the process whereby it would acquire the remaining Andros
    Inc. shares it did not own, through a merger of Andros Acquisition and
    Andros Inc. which it could cause to happen as a result of Andros Acquisition
    owning a majority of the then outstanding shares of Andros Inc. As a
    consequence of the pending merger, Andros accrued the cost of acquiring the
    remaining Andros Inc. shares outstanding and cashing out the outstanding
    options. On May 14, 1996, Andros acquired 100% of the shares of Andros Inc.
    as a result of the merger of Andros Acquisition with and into Andros Inc. in
    which Andros Inc. became a wholly owned subsidiary of Andros. Before the
    closing of the Andros Merger, the Dissenters, representing approximately
    723,000 shares of Andros Inc., exercised their appraisal rights (under
    Delaware corporate law). As part of the financing for the Andros Merger,
    Andros borrowed $27,000,000 under the Term Loan from the Banks. As a result
    of the Dissenters seeking appraisal rights for their shares, Andros did not
    have to fund the purchase of the Dissenters' shares at the time of the
    Andros Merger and had approximately $7,000,000 of excess cash. In early June
    1996, in an effort to reduce its interest costs, Andros agreed with the
    Banks to repay $7,000,000 of the Term Loan with the understanding that it
    would be able to re-borrow the same amount at a later date. On July 12, 1996
    the Dissenters withdrew their appraisal rights. At that time, Andros paid
    the Dissenters approximately $13,031,000, which it financed through
    re-borrowing the $7,000,000 it had repaid on the Term Loan in June, the
    drawing of approximately $5,400,000 under the Revolving Credit Facility and
    with approximately $631,000 of cash on hand.
 
(5) To give effect to an increase in interest expense assuming the $27.0 million
    variable rate term debt (currently 8.5%), the $15.0 million 13% subordinated
    debt, and the $5.4 million variable rate credit facility (currently 10%)
    used in the financing of the Andros Merger had been outstanding as of May 1,
    1995.

(6) To give effect to a reduction in interest income assuming the use of $26.0
    million of the cash of Andros Inc. used in the financing of the Andros
    Merger had occurred as of May 1, 1995.
 
(7) Andros acquired Andros Inc. on March 26, 1996 in a transaction accounted for
    as a purchase and recorded a $22.7 million non-recurring write-off of
    in-process technology during the period from March 27, 1996 to April 30,
    1996.
 
(8) Assumes the Andros Merger occurred as of May 1, 1995 and the resulting
    goodwill and purchased technology of $21.3 million was amortized beginning
    May 1, 1995 using a twenty-five year amortization period. The Pro forma
    adjustment represents the incremental amortization. Pro forma goodwill and
    patent amortization is $844,000 and $197,000, respectively.
 
(9) To reflect the increase in depreciation expense due to the fair market
    adjustment to fixed assets of $2.5 million resulting from the Andros Merger.
    These assets are being depreciated over their remaining useful lives, which
    average approximately five years.
 
(10) To give effect to the amortization of $3.8 million in loan origination
    costs and $1.4 million in debt discounts associated with the Andros Merger.
    The fees and discount are being amortized over the term of the loan (5
    years). Pro forma amortization of fees and discount is $707,000 and
    $345,000, respectively.
 
(11) To reflect benefits resulting from certain cost saving measures implemented
    in the year ended April 30, 1996. The following table summarizes the
    adjustments:

           service center located in Belp, Switzerland in April 1996.
 
       (c) ELIMINATION OF PUBLIC REPORTING REQUIREMENTS
 
           Costs eliminated due to the absence of public reporting requirements
           resulting from going private. These costs included shareholder
           communications, accounting and legal fees (reflects savings based on
           the difference between current fees and expected fees for a private
           company of comparable size), investor relations and annual report
           costs.
 
       (d) SELLING, GENERAL AND ADMINISTRATIVE
 
           The adjustment reflects: transaction based requirement to cover

           insurance--$122,000; and severance and related payroll taxes to a
           former officer of Andros Inc.--$228,000.
 
(12) The Pro Forma Adjustments (Novametrix) reflect the assumed issuance of
    4,389,586 shares of Novametrix Common Stock to stockholders of Andros in
    exchange for all of the outstanding shares of Andros (4,389,586 multiplied
    by the Nasdaq closing price of $5.75 per share at July 26, 1996).

    purchase price allocated to research and development in-process ($22.7
    million) and the excess of the purchase price over the fair value of net
    assets acquired (goodwill) ($8.7 million). All other assets and liabilities
    acquired are reflected in the pro forma financial statements at their
    historical cost which is assumed to approximate their fair value. The
    purchase price allocation is based on preliminary information and will be
    adjusted based on completion of appropriate valuation studies.
 
(16) The Pro Forma Adjustments (Novametrix) reflect the write off of purchased
    in-process research and development.

    warrants of Novametrix at July 28, 1996 and the resulting issuance of an
    additional 1,772,023 shares of Novametrix Common Stock pursuant to the
    Rights. The exercise of all Novametrix options and warrants will result in
    cash proceeds of $10.7 million. The issuance of shares of Novametrix Common
    Stock pursuant to the Rights will result in additional goodwill of $10.0
    million and additional annual amortization of $0.4 million.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
               CONDITION AND RESULTS OF OPERATIONS OF NOVAMETRIX
 
RESULTS OF OPERATIONS
 
    QUARTER ENDED JULY 28, 1996 COMPARED TO QUARTER ENDED JULY 30, 1995
 
    Operating results for the first quarter of fiscal 1997 ended July 28, 1996
were improved compared to the first quarter ended July 30, 1995. Net sales for
the first quarter increased to approximately $6,422,000 compared to
approximately $6,081,000 for the first quarter of the prior fiscal year. Income
before income taxes increased by 38% for the first quarter of fiscal 1997
compared to the first quarter of fiscal 1996 while net income increased by 67%
to approximately $648,000 or $.08 per share for the first quarter of fiscal 1997
compared to net income of approximately $388,000 or $.05 per share reported for
the first quarter of the prior fiscal year. Net income for the first quarter of
fiscal 1997 includes an income tax benefit of $115,000 or $.01 per share
pertaining to the reduction of the Company's deferred tax asset valuation
allowance.
 
    Net sales increased by 6% when comparing the quarter ended July 28, 1996 to
the quarter ended July 30, 1995. The increase was led by continued growth in
sales to international customers and original equipment manufacturers ("OEMs")
which was slightly offset by a modest decrease in domestic hospital sales.
 
    Cost of products sold as a percentage of net sales was unchanged overall at
43% for the first quarter of fiscal 1997 compared to the first quarter of the
prior fiscal year. The Company's continued focus on product cost improvements
and new product development is expected to have a favorable effect on margins
during the remainder of fiscal 1997.
 
    Research and product development ("R&D") expenses increased by approximately
$114,000 or 17% for the first quarter of fiscal 1997 compared to the first
quarter of fiscal 1996. The increase was primarily due to higher levels of
salaries and related fringe benefits, development materials and outside
professional services, and corresponds to the Company's aggressive product
development efforts. The Company expects to maintain its on-going R&D spending
levels at approximately 10% of net sales to continue to enhance its competitive
position.
 
    Selling, general and administrative ("S,G&A") expenses decreased by
approximately $35,000 or 2% for the first three months of fiscal 1997 compared
to the first three months of the prior fiscal year. The decreases in S,G&A
resulted primarily from cost efficiencies generated in both the international
sales and field service areas which were partially offset by increases in
domestic sales expense related to the Company's efforts to strengthen its U.S.
sales operations. Marketing expenditures increased modestly for the first
quarter of fiscal 1997 compared to the first quarter of fiscal 1996 due to
increased personnel related costs and increased travel related expenses to
support the Company's expanded clinical activities. Administrative expenses for
the three months ended July 28, 1996 remained at the same levels as the three
months ended July 30, 1995.
 
    Interest expense decreased by approximately $23,000 or 30% for the quarter
ended July 28, 1996 compared to the quarter ended July 30, 1995. The improvement
resulted primarily from reduced bank debt levels as a result of scheduled
principal payments.
 
    Income taxes for the first quarter of fiscal 1997 include $15,000 of current
income tax expense calculated on an alternative minimum tax basis due to the
Company's net operating loss carryforwards. In addition, the Company reduced its
deferred tax asset valuation allowance and recognized a benefit of $115,000 due
to continued improvement in earnings and increased probability of future taxable
income. Management will continue to evaluate whether future reductions in the
valuation allowance are warranted based on future operating performance and
other relevant factors.
 
                                       54
<PAGE>
    The Company's backlog of firm orders aggregated approximately $3,619,000 as
of July 28, 1996 compared to approximately $4,292,000 as of April 28, 1996.
Except for orders pursuant to long-term OEM agreements, the Company
traditionally ships its products on a current basis. As such, the Company does
not consider its backlog at any time to be a meaningful indicator of future
sales.
 
    YEAR ENDED APRIL 28, 1996 COMPARED TO YEAR ENDED APRIL 30, 1995
 
    Net sales increased by approximately $1.2 million or 5% to approximately
$25.3 million for the fiscal year ended April 28, 1996 ("Fiscal 1996") as
compared to net sales of approximately $24.0 million for the fiscal year ended
April 30, 1995 ("Fiscal 1995"). International sales grew by 17% for Fiscal 1996
while sales to OEM customers increased by 24% as the Company expanded its OEM
customer base. While product sales to the Company's domestic hospital markets
were approximately 6% higher for Fiscal 1996, overall domestic sales decreased
by approximately 8% due to reduced sales of the Company's products in the non-
hospital markets. The Company anticipates improvement in both hospital and
non-hospital sales in the next fiscal year as a result of strategic distribution
enhancements recently implemented as part of the Company's fiscal 1997 business
plan.
 
    Cost of sales as a percentage of net sales improved to 43% for Fiscal 1996
from 44% for the prior fiscal year primarily due to favorable product mix.
Improved margins on international sales were partially offset by relatively
modest percentage increases in domestic hospital product cost of sales. The
Company is continuing its efforts to reduce costs as a percentage of net sales
and expects new product development programs, product quality enhancements and
other cost reduction efforts to contribute to these efforts.
 
    R&D expenses increased by 12% or approximately $295,000 to $2,714,000 during
Fiscal 1996 as compared to $2,419,000 for Fiscal 1995. The increase resulted
primarily from higher levels of salaries and related fringe benefits and outside
professional services incurred in conjunction with the Company's expanded
product development efforts, which were partially offset by reductions in
engineering supplies and materials. The Company expects its R&D spending to
continue to approximate 10% of net sales for fiscal 1997.
 
    S,G&A expenses increased by approximately 2% to $9,137,000 for Fiscal 1996
as compared to $8,978,000 for Fiscal 1995. Increased selling expenses associated
with higher levels of sales, particularly in the international area, were
partially offset by reduced marketing expenses. Increased salaries and related
fringe benefits in the marketing area were offset by decreased outside
professional services. General and administrative expenses increased nearly 8%
during Fiscal 1996 primarily as a result of increased legal, external reporting
and recruitment expenses.
 
    Interest expense during Fiscal 1996 decreased by 23% as a result of lower
debt levels primarily associated with the Company's public offering consummated
during the first quarter of Fiscal 1995 (June 1994), and scheduled principal
payments.
 
    Current income tax expense of $40,000 for Fiscal 1996 was unchanged from
Fiscal 1995 and was calculated on an alternative minimum tax basis after
utilizing a portion of the Company's net operating loss carryforwards. In 1995
and prior years, the Company maintained a valuation allowance for the total
amount of net deferred tax assets related to tax credit carryforwards, net
operating loss carryforwards and temporary timing differences since management
believed that it was uncertain whether the tax benefits associated with these
assets would ultimately be realized. Because of the continued improvement in the
performance of the Company in 1996, management believes that it is more likely
than not that a portion of these benefits will be realized and, in accordance
with the provisions of Statement of Financial Accounting Standards No. 109, has
reduced the valuation allowance and recognized a benefit of $1,020,000 in the
1996 financial statements. Management will continue to evaluate whether further
reductions in the valuation allowance are warranted based on future operating
performance and other relevant factors.

    YEAR ENDED APRIL 30, 1995 COMPARED TO YEAR ENDED MAY 1, 1994
 
    Net sales increased by 16% to approximately $24,000,000 in Fiscal 1995
compared to net sales of approximately $20,800,000 in the fiscal year ended May
1, 1994 ("Fiscal 1994"). International revenue growth of 28% was the largest
single contributing factor. Sales of sensors and electronics to OEM customers
who utilize the Company's technology in their systems, were responsible for
approximately $1.4 million of the growth in overall sales revenues. Sales to
domestic markets were 2 percent lower than sales to these markets recorded in
Fiscal 1994. The Company expected continued improvement in international and OEM
sales levels in Fiscal 1996, and domestic sales were also expected to strengthen
as the result of strategic changes implemented in the domestic sales effort.
 
    Cost of sales as a percentage of net sales increased from 43% to 44% when
comparing Fiscal 1995 to Fiscal 1994, primarily due to the higher international
content of net sales reported. On-going quality and cost reduction efforts, with
significant contributions from both the manufacturing and new product
development areas, were expected to minimize any potential impact on margins due
to the continued growth of international sales as a percentage of overall
revenues.
 
    R&D expenses increased by 24% to approximately $2,419,000 compared to
$1,954,000 reported in Fiscal 1994. This increase of almost $465,000 resulted
primarily from higher levels of salaries and related fringe benefit costs,
supplies, and outside services associated with increased product development
efforts. Costs associated with providing new OEM customers with technical
development assistance, and increased depreciation expense associated with
higher levels of assets, also contributed to the year-to-year increase.
 
    S,G&A expenses increased by 5% when comparing Fiscal 1995 expenses to Fiscal
1994 expenses. Selling, marketing and service related administrative costs
accounted for 3% of the overall S,G&A increase as the result of increased
international selling expenses associated with the higher levels of sales
activities abroad, partially offset by a reduction in domestic selling and
marketing expenses. General and administrative expenses accounted for the
remaining 2% due to increased accounting and reporting fees, and higher
insurance costs. The Company expected to commit additional resources toward
enhancing domestic hospital and non-hospital revenues in Fiscal 1996, as well as
supporting the increases in international sales activities.
 
    Interest expense in Fiscal 1995 decreased by 46% compared to Fiscal 1994 due
to significantly lower debt levels as the result of the public offering
consummated in June 1994. Scheduled principal payments during Fiscal 1995 also
contributed to the lower debt levels, and were expected to continue to have a
positive impact on interest expenses in Fiscal 1996.
 
    Other expense (income), net, exclusive of the favorable $140,000 settlement
of a contractual dispute in Fiscal 1994, increased by approximately $9,000
compared to Fiscal 1994.
 
    Income tax expense of $40,000 for Fiscal 1995 resulted from higher taxable
income levels compared to the prior year and was calculated on an alternative
minimum tax method after the utilization of a portion of the Company's net
operating loss carryforwards.
 
LIQUIDITY AND SOURCES OF CAPITAL
 
    The Company requires sufficient liquidity to source its working capital
needs which are primarily inventory, accounts receivable and debt service. Cash
flow from operations is the principal source of the Company's working capital.
The Company also has available borrowing under its revolving credit facility to
cover periodic fluctuations in its working capital requirements and further,
believes that additional funds, if required, could be obtained from various
sources on commercially reasonable terms. In addition, the Company has
approximately $5,600,000 of additional net proceeds that may be realized upon
the exercise of both Class A and Class B Warrants issued in June 1994, which are
redeemable by the Company under specified conditions.
 
    The Company had working capital of approximately $8,982,000 at July 28, 1996
compared to working capital of approximately $8,364,000 at April 28, 1996. The
Company's current ratio of 3.1 to 1 remained unchanged at July 28, 1996 from
April 28, 1996. The increase in working capital of approximately $618,000
 
                                       56
<PAGE>
was primarily generated by increases in accounts receivable and prepaid
expenses, offset by increases in accrued expenses.
 
    Approximately $217,000 of cash was provided by operations for the three
months ended July 28, 1996 compared to approximately $107,000 for the three
months ended July 30, 1995. Increases in net income before depreciation,
amortization and deferred income tax benefits combined with increases in accrued
expenses, partially offset by increases in accounts receivable and prepaid
expenses, accounted for the increase.
 
    The Company had additional borrowing capacity of approximately $1,525,000
available for working capital needs under its revolving credit facility at both
July 28, 1996 and April 28, 1996. In addition, the warrants associated with the
public offering are callable by the Company, 50% after December 8, 1995 and 50%
after December 8, 1996, in each case if the common stock price of the Company
exceeds specified levels. The Company believes that cash from operations will be
sufficient to fund cash requirements for fiscal 1997.
 
IMPACT OF INFLATION
 
    The rate of inflation continues to have a marginal impact on the operations
of the Company. While management routinely assesses the possible effects of
inflation with respect to the Company's future business plans, the rate of
inflation is not expected to have a material impact upon the growth of the
Company during fiscal 1997.
 
RISKS ASSOCIATED WITH THE NOVAMETRIX BUSINESS
 
    Set forth below are some of the material risks associated with Novametrix'
business and operations:
 
    (i) The electronic medical instrumentation industry is characterized by
rapid technological changes and advances. Although the Company believes that its
products are technologically current, the development of new technologies or
refinements of existing ones could at any time make the Company's existing
products technologically or economically obsolete.
 
    (ii) The Company and one of its wholly owned subsidiaries hold patents and
have patents pending related to certain of the Company's products. If the
Company's products are determined to use technology, processes or other subject
matter that is claimed under other existing U.S. or foreign patents, or if other
companies obtain patents claiming subject matter utilized by Novametrix, such
companies may bring infringement actions against Novametrix. The Company may not
have the resources necessary to challenge successfully the validity of such
patents or withstand claims of infringement in cases where the Company's
position has merit. Even if Novametrix were to be successful in prevailing in
such actions, the cost of such litigation could have a material adverse effect
on the Company's results of operations. An adverse outcome could subject
Novametrix to significant liabilities to third parties, require disputed rights
to be licensed or require Novametrix to cease using such technology. There can
be no assurance that the Company will be able to obtain such licenses or that
such licenses, if available, can be obtained on commercially reasonable terms.
 
   (iii) The Company relies on trade secrets and proprietary know-how, which it
will seek to protect, in part, by confidentiality agreements with certain of its
employees, suppliers and customers. However, if the Company's confidentiality
agreements are breached, if the Company does not have adequate remedies for any
such breach or if the Company's trade secrets or proprietary know-how otherwise
become known or independently discovered by competitors, the Company's business
could be materially adversely affected.
 
    (iv) The electronic medical instrumentation industry is extremely
competitive. The Company's competitors vary in size from entities which are
smaller than the Company to divisions or subsidiaries of multinational
corporations. Some of these competitors also have extensive production
facilities, well established marketing and service organizations, recognized
reputations in the electronic medical instrumentation industry and far greater
financial resources than the Company has or will have in the foreseeable future.
 
                                       57
<PAGE>
    (v) The Company's products are "medical devices" within the meaning of a
1976 amendment to the Federal Food, Drug and Cosmetics Act. Under the amendment,
a manufacturer must obtain approval by the United States Food and Drug
Administration (the "FDA") of a new medical device before it can be marketed in
the United States. The approval process requires that the safety and efficacy of
such devices be demonstrated by the manufacturer to the FDA. Under certain
circumstances, the cost of obtaining such premarketing approval may be high and
the process lengthy. All of the products currently marketed domestically by the
Company requiring pre-marketing approval from the FDA have been so approved.
 
    Following regulatory approval, commercially marketed products, as well as
the manufacturer and manufacturing facility, are subject to periodic review and
inspections. In the event of a discovery of previously unknown problems with a
Novametrix product, then restrictions on the product or Novametrix, including
recalls (which could require costly redesign or reconfiguration of Novametrix'
product) or even withdrawal of the product from the market could result, any of
which could have a material adverse effect on Novametrix.
 
    In the future, certain other industry-wide performance standards with
respect to safety and efficacy of medical products are likely to be promulgated
by the FDA. The FDA has not yet developed industry-wide performance standards
with respect to the safety and effectiveness of those products manufactured by
the Company which would be subject to such standards. When and if these
standards are adopted, the Company will be required to submit data demonstrating
compliance with the standards (during which period the Company may be permitted
to continue to market products which have previously been approved by the FDA).
There can be no assurance that the Company's products will comply with the
applicable industry-wide performance standards when and if adopted or that the
Company will receive the requisite approval to market any of its future
products. Any failure to receive approvals or non-compliance with performance
standards would have a material adverse effect on the Company's business and
financial position.
 
    Various countries in which the Company markets its products have regulatory
agencies which perform functions comparable to the FDA. To date, foreign
regulations have not adversely affected the Company's business; however, there
can be no assurance that any such regulations will not have a material adverse
affect on the Company's business and financial condition in the future.
 
    (vi) The Company believes that its success will be highly dependent upon its
continued ability to attract and retain skilled managers and engineering
personnel, including its President and Chief Executive Officer, William J.
Lacourciere.
 
   (vii) Substantially all of the components in the Company's products are
manufactured by others and then assembled by the Company. The Company's assembly
operations require a variety of electronic and mechanical components and
supplies as well as specialized assembly equipment. The Company has not
experienced any interruption of production or supplies of components, supplies
or equipment. Interruption of the Company's sources of supply or quality
problems with supplied components would have a material adverse effect on the
Company's business and financial position.
 
  (viii) From time to time, the Company is subject to product liability claims,
suits and complaints incidental to its business. These claims, suits and
complaints are covered by insurance policies maintained by the Company, subject
to certain policy limits. In addition, certain of the Company's OEM agreements
require the Company to maintain minimum levels of product liability insurance.
The Company currently maintains product liability insurance in the amount of
$5,000,000 with a $50,000 per occurrence deductible up to an aggregate annual
deductible of $250,000. This product liability insurance meets the minimum
standards set by all of the Company's current OEM agreements; however, there can
be no assurance that the Company will not enter into additional OEM agreements
in the future which require greater product liability insurance. The Company is
not aware of any pending product liability claims, suits or complaints the
disposition of which, in the opinion of management, would have a material
adverse effect upon the Company's business, financial position or liquidity. The
Company, however, could be materially adversely affected by successful product
liability claims, and there can be no assurance that the Company will have
sufficient resources to satisfy any liability resulting from claims not covered
by existing insurance policies.
 
                                       58
<PAGE>
    (ix) Sales to foreign customers constitute a significant portion of the
Company's total net sales. The Company intends to continue to improve and expand
its sales efforts in countries worldwide and expects international sales to
continue to constitute a significant portion of the Company's total net sales.
Sales in foreign countries of electronic medical devices are subject to a number
of risks, including regulatory requirements, foreign currency fluctuations, the
imposition of tariffs and import and export controls, changes in government
policies (including United States policy toward these countries), and other
factors which could have a material adverse effect on the Company's business and
financial position.

                              NOVAMETRIX BUSINESS
 
GENERAL
 
    Organized in 1978, the Company is engaged in the business of designing,
developing, manufacturing and marketing monitors and sensors which provide
continuous and non-invasive measurements of a patient's blood gas levels (oxygen
and carbon dioxide) and respiratory mechanics (lung pressure, flow and volume).
The Company's current product line consists of the following:
 
    - Capnographs--monitors which measure the level of exhaled carbon dioxide.
 
    - Pulse Oximeters--monitors which measure arterial blood oxygen saturation
      levels and pulse rates.
 
    - Transcutaneous Blood Gas Monitors--monitors which measure oxygen and
      carbon dioxide levels through the skin.
 
    - Respiratory Mechanics Monitor--a monitor which measures pressure, flow and
      volume in a patient's airway and lungs.
 
    - Reusable and disposable sensors and adapters, related accessories and
      replacement parts.
 
BLOOD GAS MONITORS
 
    Levels of oxygen and carbon dioxide in the blood are important indicators of
the condition of critically ill or injured patients. These levels are
particularly important to doctors, nurses, therapists and other clinicians
during anesthesia in the operating room, the assessment of a patient in the
emergency room, the monitoring of a patient in the intensive care unit and
recovery room and throughout respiratory care applications. Healthy people have
a normal range of oxygen and carbon dioxide levels in their blood, lungs and
other tissue. Also, depending on a person's size and age, there is a range of
normal airway and lung pressure, flow and volume levels. By continuously
monitoring these ranges, a change in a patient's status can be detected at an
early stage and modified before serious deterioration in a patient's condition
occurs. In addition, if a patient's blood gas levels or respiratory mechanics
are outside their normal ranges, continuous monitoring provides healthcare
professionals with important information concerning the progress of the medical
treatment undertaken to bring them back within normal ranges.
 
    Previously, the only methods of determining the body's oxygen and carbon
dioxide levels involved invasive techniques of withdrawing blood samples from a
patient's artery and waiting for laboratory analysis of the samples. The
Company's products offer healthcare providers the alternative of non-invasive,
continuous and immediate measurement of oxygen and carbon dioxide. The Company's
blood gas monitoring products utilize three different technologies, each of
which is suitable for different applications.
 
    CAPNOGRAPH MONITORS.  The Company's capnographs (or end-tidal carbon dioxide
monitors) provide a continuous, non-invasive measurement and display of the
amount of carbon dioxide in each breath exhaled by the patient. Clinically,
end-tidal carbon dioxide levels have been correlated to a patient's arterial
blood carbon dioxide levels. Measurement of these levels provides a simple,
non-invasive method of estimating the carbon dioxide levels of the patient.
Applications for capnographs include (i) intubation verification, the
verification of the introduction of an airway tube into the trachea (air tube)
rather than the esophagus (food tube) and the verification of an open and
unobstructed airway; (ii) extubation detection, the disclosure of the accidental
dislodging from the trachea of an airway tube; (iii) ventilation management
through the disclosure of ventilator malfunctions and the proper adjustment of
mechanical ventilation to match a patient's condition and needs; and (iv)
verification of the effectiveness of cardio-pulmonary resuscitation (CPR).
 
    The Company's capnographs utilize a form of infrared spectrometry (a method
of analyzing gas content by measuring the amount of infrared energy absorbed)
developed by the Company to measure levels of expired carbon dioxide throughout
the patient's respiratory cycle. These monitors provide both a graphical and
digital display of carbon dioxide levels and respiratory rate. The reliability
and accuracy of capnography have made its use a rapid indicator of proper and
continuous intubation, obstructions in the
 
                                       60
<PAGE>
airway and pulmonary efficiency in eliminating carbon dioxide. In addition,
end-tidal carbon dioxide and respiratory rate measurements facilitate proper and
cost efficient ventilator use. In recognition of its accurate measurement of
clinically significant facts, as well as the added degree of safety that it
affords patients, capnography has been recommended for use in the operating room
by the American Society of Anesthesiologists and in the intensive care unit by
the Society of Critical Care Medicine.
 
    The Company has two bedside capnographs which are portable devices: the
CAPNOGARD-TM-, a lightweight capnograph (measuring approximately 3" high, 9"
wide and 8" deep, and weighing 8 pounds), and the CO(2)SMO-TM-, a combined
capnograph and pulse oximeter which is the same size as the CAPNOGARD-TM-. These
"mainstream" (on the airway) capnographs are designed to take measurements at
the patient's airway through infrared measurement as compared to "sidestream"
measurements of exhaled breath which involves the drawing of samples through
tubes connected to bedside monitors and are susceptible to moisture and other
secretion contaminants. Both models utilize a new generation, durable and
solid-state sensor developed by the Company. These monitors also permit sampling
on non-intubated patients. The CAPNOGARD-TM- has a list sales price of
approximately $7,500 and the CO(2)SMO-TM- has a list sales price of
approximately $9,500.
 
    PULSE OXIMETERS.  The Company's pulse oximeters provide a continuous and
non-invasive measurement and display of pulse rate and arterial blood oxygen
saturation through the detection and measurement of infrared light absorbed by
hemoglobin in the blood. Reusable finger and multi-position sensors
(Y-Sensor-TM-) are available for adult, pediatric and neonatal applications and
eliminate the use of costly disposable sensors. Pulse oximeters have been
clinically demonstrated as safe, accurate and cost-effective for the
determination and trending of levels of blood oxygen saturation and pulse rates.
Applications for these monitors are widespread since the level of oxygen in a
patient's blood can be as important a vital sign of a patient's condition as the
patient's temperature, blood pressure, respiratory rate and electrocardiogram.
Pulse oximetry is used in many departments of the hospital, including the
operating room by anesthesiologists, emergency rooms and intensive care units by
nurses and respiratory therapists and neonatal intensive care units by
neonatologists. Additional applications include inter- and intra-hospital
transport situations and clinical applications in surgical centers, doctors'
offices and clinics during outpatient procedures.
 
    The Company has a family of pulse oximeters designed to meet the individual
needs of clinicians in a variety of settings. Each oximeter utilizes the
Company's reusable Superbright-TM- sensors, which provide safe and accurate
results on all types of patients, including neonates (an infant less than 28
days old) and poorly perfused patients (patients with insufficient blood flow).
The Company's full-featured oximeter, the OXYPLETH-TM- provides high visibility
of the plethysmographic waveform (a graphic display of arterial pulse, also
known as a plethysmogram) through the use of digital technology combined with
advanced software developed by the Company. The Model 515B (and Model 515C with
plethysmogram) pulse oximeters utilize the same basic technology and software as
its more expensive model to provide the same oxygen saturation and pulse rate
information but with fewer available added features.
 
    This family of pulse oximeters also includes a battery operated handheld
pulse oximeter, the SPO(2)TX-TM-. Measuring approximately 6" high, 4" wide and
1" deep and weighing less than 1 pound, this monitor's lightweight design and
portability permits wide applications such as use in emergency transport
situations, doctors' offices, clinics during outpatient procedures and
performance of spot checks on patients in all areas of the hospital. The
Oxypleth has a list sales price of approximately $3,000. The Model 515B, Model
515C and SPO(2)TX-TM- have list sales prices of approximately $2,000, $2,200 and
$1,000, respectively.
 
    TRANSCUTANEOUS BLOOD GAS MONITORS.  The Company's transcutaneous (through
the skin) blood gas monitor provides continuous and non-invasive measurements of
oxygen and carbon dioxide levels in the skin tissue of patients. This monitor
utilizes dual parameter sensors attached to the patient's skin surface to
measure the amount of oxygen and carbon dioxide diffusing through the skin.
Based upon the magnitude of the diffusion of the blood gas molecules, the
monitor converts the sensor readings into a value corresponding to the oxygen or
carbon dioxide at the patient's skin surface and displays the information on
 
                                       61
<PAGE>
the monitor. Premature and other critically ill newborn infants are the primary
patients who benefit from the use of transcutaneous monitoring. In view of their
limited blood supply, frequent invasive blood sampling has been recognized as
traumatic and unsatisfactory for these patients. The Company intends to continue
to develop and enhance its transcutaneous blood gas monitor for neonatal and
adult use in intensive care and vascular medicine applications.
 
    The Company's Model 840 transcutaneous monitor utilizes a simple menu-driven
system which takes the user through automatic calibration procedures, histogram
(graphical representation of data collected over time) and printout options.
This monitor, which features a bright, easy-to-read, vacuum fluorescent digital
display ("VFD") has a list sales price of approximately $6,500 to $8,500
depending on its configuration.
 
RESPIRATORY MECHANICS MONITOR
 
    The Company's respiratory mechanics monitor, the VenTrak-TM- Model 1550,
provides continuous and non-invasive measurements of the pressure, flow and
volume in a patient's airway, as well as measurements of other pulmonary
mechanics parameters. Optimal carbon dioxide elimination and arterial
oxygenation during mechanical ventilation require the clinical management of the
pressure, flow and volume of airway gases being administered. Applications for
this monitor include the clinical management of the proper pressure and flow of
airway gases being delivered to a ventilated patient's lungs, allowing
therapists to wean a patient from expensive mechanical ventilation to
spontaneous breathing at the clinically appropriate and most cost-effective
time. The Model 1550, when combined with Novametrix's capnography and airway
flow monitoring technologies, provides continuous measurements of pulmonary dead
space and carbon dioxide production (SBCO(2) - single breath CO(2)). The Company
believes that deadspace and CO(2) production are parameters that have,
heretofore, been unavailable in a bedside monitor. The real-time knowledge of
pulmonary deadspace, the portion of a patient's lungs which do not participate
in gas exchange, concurrently with CO(2) production, the volume of CO(2) exhaled
by the patient, and the impact of each parameter by ventilator changes, provides
the bedside clinician with very important feedback to optimize the patient's
care. Thus, use of the Model 1550 enhances patient care by minimizing the
trauma, length of stay and the costs associated with mechanical ventilation.
 
    Respiratory therapy and critical care departments with patients requiring
mechanical ventilation represent the primary users of the Company's respiratory
mechanics monitor.
 
    The VenTrak-TM- monitor (excluding the capnograph) has a list sales price of
approximately $9,400 to $13,000 depending on its configuration.
 
    The Company also maintains the exclusive rights for the commercial
manufacture and marketing of a family of disposable airway flow sensors. This
patented technology provides the Company with lower manufacturing costs than
previous types of flow sensors and improves the accuracy of information
currently obtainable from these monitors.
 
SALES, MARKETING AND CUSTOMERS
 
    The Company markets its products domestically and internationally directly
through salespersons and outside distributors to its customers, most of which
are hospitals. All of the Company's blood gas and respiratory mechanics products
are marketed primarily to hospitals for use in operating rooms, emergency rooms,
intensive care units, respiratory therapy departments, transport situations and
in other departments where critically ill or injured patients require
monitoring. The Company expects to increase further its marketing efforts to
physician groups and other healthcare facilities such as nursing homes, surgical
centers and outpatient clinics through the use of manufacturers' representatives
experienced in these marketplaces.
 
    The Company also markets its products directly to OEMs which incorporate
certain of the Company's products and technologies in the manufacture of their
own multi-parameter systems, ventilators and other non-competing products.
Generally, the Company sells its products to OEM customers pursuant to long-
 
                                       62
<PAGE>
term contracts which, in certain cases, provide for the purchase of minimum
quantities of products at specified prices. The Company assembles the products
to be sold to OEM customers and, generally, also agrees to provide maintenance
and replacement parts. The Company continues to seek new agreements with other
OEM customers and additional agreements for other products with its current
customers. To support this effort fully, the Company hired an OEM Sales and
Marketing Manager during Fiscal 1996. There can be no assurance however that the
Company will be successful in obtaining other long-term OEM contracts.
 
    The Company employs a 17-person direct United States sales force and also
utilizes six outside distributors in the United States to sell its products.
Typically, these distributors sell other medical instruments and products, but
do not sell products which compete directly with those offered by the Company.
 
    Internationally, the Company currently employs six sales and marketing
managers and has approximately 85 outside international distributors. The
Company markets its products in over 75 countries worldwide. The Company's
international net sales of products and services constituted 45%, 39% and 35% of
the Company's total net sales during Fiscal 1996, 1995 and 1994, respectively.
The Company is engaged in continuing efforts to improve and expand the
international distribution of its products and expects international sales to
continue to constitute a significant portion of the Company's total net sales.
 
    Many of the countries into which the Company sells its products require
governmental approval for the sale of the Company's medical instruments. In most
countries which require approval, the approval process is shorter than that in
the United States and, generally, the Company shares the costs associated with
the approval process with its international distributors. The Company believes
it has all necessary approvals to sell the products which it currently
distributes internationally.
 
    All of the Company's international sales are denominated in United States
dollars. However, the volume of export sales of the Company's products may be
affected by fluctuations in the rate of exchange of the United States dollar for
the currency of the country in which sales are made. The Company believes that
prior fluctuations in the strength of the United States dollar have had a
minimal impact on international sales of its products.
 
    No customer accounted for more than 10% of the Company's net sales in Fiscal
1996, 1995 or 1994.
 
    Advertising of the Company's products consists primarily of displays at
medical meetings and trade shows. The Company also advertises in trade journals
and periodicals and cooperates in the publication of technical papers written by
medical authorities in areas relating to the Company's products.
 
RESEARCH AND DEVELOPMENT
 
    The Company's research and development activities are devoted to the design
and development of new monitor and sensor technologies and to the development
and enhancement of its existing products. The Company anticipates offering new
products in the future, however there can be no assurance that the Company will
introduce new products in successive fiscal years. With the advent of managed
care and continuing healthcare cost containment efforts, these research and
development activities are focused on providing technology and related products
which measure and record medically necessary information in a safe and
cost-effective manner.
 
    The Company's research and development activities presently are, and during
the foreseeable future are expected to be, devoted primarily to the development
and enhancement of the Company's existing products and technologies and to the
design and development of new products. For Fiscal 1996, 1995 and 1994, the
Company incurred aggregate expenses of approximately $7,087,000 for these
activities. Approximately $2,714,000 was attributable to Fiscal 1996,
approximately $2,419,000 to Fiscal 1995 and approximately $1,954,000 to Fiscal
1994. All of the Company's research and development activities are sponsored by
the Company.
 
                                       63
<PAGE>
    The Company's Cascadia Technology Division, located in Redmond, Washington,
is principally engaged in research and development. The research and development
portion of expenses related to this division are included in the amounts stated
in the preceding paragraph.
 
PRODUCTION AND SERVICE
 
    Substantially all of the components in the Company's products are
manufactured by others and then assembled by the Company. The Company's assembly
operations require a variety of electronic and mechanical components and
supplies, as well as specialized equipment which the Company owns or leases.
 
    The Company does not have any long-term contracts with any of its suppliers
and believes that the needed components and supplies are available from
alternate sources. The Company has not experienced any interruption of
production or deliveries of components, supplies or equipment. However, there
can be no assurance that the Company will continue to receive timely service or
that the Company would be able to find readily a substitute manufacturer if one
were needed on short notice. Interruption of the Company's sources of supply or
quality problems with the supplied components could have a material adverse
effect on the Company's business and financial position.
 
    The Company provides maintenance service for its products through service
technicians who are employees of the Company and through independent service
representatives. The Company's products utilize modular components which have
been designed for maximum maintenance accessibility and ease of removal for
repair or replacement. The Company warrants its products against defects in
material and workmanship, including parts and labor, for one year or more,
except for certain non-capital items which the Company warrants for shorter
periods. The Company also offers extended warranty programs that may be
purchased by its customers. Historically, the Company's annual warranty expenses
have been immaterial.

(1) On March 26, 1996, Andros Acquisition, a wholly owned subsidiary of Andros,
    closed the Tender Offer for all of the shares of Andros Inc. for $18.00 per
    share. As a result of the Tender Offer, Andros Acquisition acquired
    approximately 58% of the outstanding shares of Andros Inc. At this time,
    Andros initiated the process whereby it would acquire the remaining Andros
    Inc. shares it did not own through a merger of Andros Acquisition and Andros
    Inc. which it could cause to happen as a result of Andros Acquisition owning
    a majority of the then outstanding shares of Andros Inc. As a consequence of
    the pending merger, Andros accrued the cost of acquiring the remaining
    Andros Inc. shares outstanding and cashing out the outstanding options. On
    May 14, 1996, Andros acquired substantially all of the remaining shares of
    Andros Inc. as a result of the merger of Andros Acquisition with and into
    Andros Inc. in which Andros Inc. became a wholly owned subsidiary of Andros.
    The accompanying consolidated financial statement data include the financial
    statement data of Andros Inc. from July 31, 1995 through March 26, 1996 and
    Andros, including its subsidiary, Andros Inc., from March 27, 1996 through
    July 31, 1996. The selected financial data of Andros and Andros Inc. are
    qualified in their entirety by, and should be read in conjunction with, the
    financial statements of Andros and Andros Inc., including the notes thereto,
    and "Management's Discussion and Analysis of Financial Condition and Results
    of Operations of Andros" included elsewhere herein. The Statement of
    Operations Data and Balance Sheet Data for the years ended July 31, 1996,
    July 30, 1995, July 31, 1994 and July 25 1993, and for the period from July
    31, 1995 to March 26, 1996 and the Balance Sheet Data as of July 31, 1996,
    July 30, 1995 and July 31, 1994 are derived from, and are qualified by
    reference to, the audited financial statements included elsewhere in this
    Proxy Statement. The Statement of Operations Data and Balance Sheet Data for
    the fiscal year ended July 26, 1992 are derived from audited financial
    statements not included herein.
 
(2) Andros acquired the outstanding common shares of Andros Inc. in a cash
    purchase effective March 26, 1996. The purchase was recorded in accordance
    with APB No. 16 "Business Combinations". See Note 1 on page F-20, "Basis of
    Presentation."

TWELVE MONTHS ENDED JULY 31, 1996 COMPARED TO TWELVE MONTHS ENDED JULY 30, 1995
 
    Genstar formed Andros for the purpose of acquiring Andros Inc. (a U.S.
publicly traded corporation). On March 26, 1996 Andros, through Andros
Acquisition, a wholly owned subsidiary, purchased, through a public tender offer
approximately 58% of the outstanding stock of Andros Inc. As of May 14, 1996,
Andros acquired substantially all of the remaining Andros Inc. shares it had not
acquired on March 26, 1996. Upon the completion of the acquisition of Andros
Inc., Andros Acquisition was merged into Andros Inc., leaving Andros Inc. as a
wholly owned subsidiary of Andros.
 
    The acquisition of Andros Inc. was accounted for as a purchase in accordance
with APB No. 16 "Business Combinations", as of March 27, 1996.
 
    Andros' sales increased marginally to approximately $43,160,000 in 1996
compared to $42,753,000 in 1995. The increase in sales resulted from higher
sales for worldwide medical, international automotive, automotive service, and
Scitec products, offset by lower domestic automotive sales.
 
    Worldwide medical sales increased 12% to $14,971,000 for 1996 largely due to
the introduction of Andros' model 4700 Anesthesia Monitoring System. This was
partially offset by changes in order patterns of certain of Andros' customers in
the U.S., Europe and the Far East, as they continued to bring their inventories
in line with expected revenues.
 
    International automotive sales increased 40% to $17,841,000 for 1996
compared to the same period last year mainly due to demand generated by the
ongoing MOT inspection and maintenance program in the United Kingdom.
 
    Automotive service and parts sales increased 12% to $3,872,000 for 1996
compared to a year ago, generally due to a larger installed base.
 
    Scitec sales increased 6% to $3,072,000 for 1996 compared to the same period
a year ago. This increase in sales was primarily a result of the introduction of
the new MAP 4 product, partially offset by a decline in service revenue.
 
    U.S. automotive sales decreased 67% to $3,403,000 for 1996 compared to the
year ended July 30, 1995 due mainly to the cancellation of the IM 240 program
and delays in the implementation of state ASM programs. Management believes that
the sales decrease was also attributable to customer uncertainty with respect to
the timing of implementation of the ASM programs in different states.
 
    Cost of sales as a percentage of sales was 77% at $33,080,000 for 1996
compared to 59% at $25,428,000 for the same period a year ago. During the period
July 31, 1995 to March 26, 1996, Andros
 
                                       66
<PAGE>
increased its reserves for obsolete inventory by $3,866,000 based on decreased
demand and changes in market preferences, particularly relating to products
designed for the IM 240 program. Also, included in this same period were
inventory write-offs and order cancellation charges totaling $1,849,000.
Excluding the effect of these adjustments, cost of sales as a percentage of net
sales increased from 60% to 63% when comparing the twelve months ended July 31,
1996 to the comparable period in 1995, primarily due to increased material costs
and variations in the sales mix.
 
    Warranty expense increased from $816,000 for the twelve months ended July
31, 1995, to $1,977,000 for the same period ended July 31, 1996 primarily due to
estimated costs associated with its medical gas analyzer.
 
    Andros' research, development and engineering expenses were $4,602,900 for
the twelve months ended July 31, 1996 and $5,100,900 for the year ended July 30,
1995. The change is attributable to a reduction in headcount and related
operating expenses.
 
    Marketing, general and administrative expenses excluding warranty and bad
debt expenses discussed elsewhere were $9,124,700 for the twelve months ended
July 31, 1996 compared to $8,977,000 for the year ended July 30, 1995. The
increase was attributable to approximately $3.2 million of items discussed below
offset by a reduction in headcount and related operating expenses.
 
    In conjunction with the Andros Merger, the amount allocated to purchased
technology and in-process technology at the acquisition date was determined by
recognized valuation techniques in the high technology industry. The commercial
viability of the in-process technology had not been established and had no
identifiable alternative future use. Accordingly, the entire $22,700,000 was
charged to operations in 1996.
 
    In connection with the acquisition of Andros Inc. by Andros, as of March 26,
1996, all of the outstanding Andros Inc. employee stock options whether or not
then exercisable (other than 98,400 options that were exchanged for equity unit
awards) were exchanged for cash payments. The net expense of the acquisition of
these options of approximately $4,113,800 representing the excess of the $18.00
per share over the grant price has been recorded as an expense.
 
    In March 1996, in conjunction with the Andros Merger, Andros increased its
provision for bad debts as a result of the worsening financial condition of
several of its customers and to reflect anticipated negative outcomes of
disputed accounts receivable balances. Total bad debt expenses were $996,400 and
$408,800 for the twelve months ended July 31, 1996 and July 30, 1995,
respectively.
 
    During the period from July 31, 1995 to March 26, 1996, interest income was
$836,200 and during the period from March 27, 1996 to July 31, 1996, interest
income was $283,900. Interest income for the twelve months ended July 31, 1995
was $1,355,000. The decrease is attributable to the use of Andros Inc.'s cash
and available for sale securities to fund the acquisition of Andros Inc. by
Andros.
 
    During the period from July 31, 1995 to March 26, 1996, interest expense was
$6,000 and during the period from March 27, 1996, to July 31, 1996, interest
expense was $1,909,700. The increase in interest expense was a result of the
debt incurred by Andros in connection with the acquisition of Andros Inc. by
Andros.
 
    The provision (benefit) for income taxes for the twelve months ended July
31, 1996 consists of ($1,724,700) current federal, ($2,999,800) deferred
federal, and ($290,600) deferred state income taxes. The effective tax rate was
(44.2%) and 2.8% for the period from July 31, 1995 to March 26, 1996 and March
27, 1996 to July 31, 1996, respectively.
 
    Included in the condensed statement of operations for the twelve months
ended July 31, 1996, were $8,343,000 of certain charges and costs incurred by
Andros. Management is of the opinion that the
 
                                       67

inclusion of these charges and costs in the condensed statement of operations

    Total operating expenses, including the items discussed below, increased
$28,213,300 to $43,516,000 during 1996 as compared to $15,302,700 for the same
period a year ago. Excluding the effect of the adjustments enumerated above,
operating expenses decreased 21% to $12,152,000 for the twelve months ended July
31, 1996, compared to $15,302,700 for the same period a year ago, due to cost
savings measures and control over operating expenses.
 
FISCAL YEAR ENDED JULY 30, 1995 COMPARED TO FISCAL YEAR ENDED JULY 31, 1994
 
    Andros' sales for the fiscal year ended July 30, 1995 ("Andros' Fiscal
1995") decreased 26% from sales reported for the fiscal year ended July 31, 1994
("Andros' Fiscal 1994"). This decrease in sales resulted primarily from the
reduction of sales related to the now-completed German upgraded vehicle
inspection program. Fiscal 1994 included approximately $14 million in sales
related to the German vehicle inspection program compared with minimal sales in
Andros' Fiscal 1995. Revenue for Andros' Fiscal 1995 was also adversely affected
by a delay in implementation of various states' emissions programs, as well as
unexpected shipment delays of the MAP 4 product developed by Andros' Scitec
subsidiary. Volume shipments of the MAP 4 commenced in December 1995.
 
    International automotive product sales decreased 53% to $12,732,000 for
Andros' Fiscal 1995 from Andros' Fiscal 1994 for the reasons stated above with
respect to the German program.
 
    U.S. automotive product sales increased 6% to $10,320,100 for Andros' Fiscal
1995 over Andros' Fiscal 1994 due primarily to the increased demand for new or
enhanced versions of Andros' Model 6000 Series Automotive Exhaust Analyzers and,
to a lesser extent, the improvements in the U.S. economy and variations in order
patterns from automotive customers. Automotive service revenues increased 12% to
$3,457,200 for Andros' Fiscal 1995 over Andros' Fiscal 1994, generally due to a
larger installed base.
 
    Worldwide medical parts and service revenue decreased 11% to $13,359,000 in
Andros' Fiscal 1995 over Andros' Fiscal 1994. Andros believes that the decrease
was mainly a result of a decrease in orders by certain customers in the U.S. and
Europe in Andros' Fiscal 1995, as customer inventories were brought in line with
expected revenues, partially offset by sales increases to customers located in
the Far East.
 
    Gross margins were 41% for Andros' Fiscal 1995, unchanged from Andros'
Fiscal 1994. However, gross margins in the fourth quarter of Andros' Fiscal 1995
were 37% due to increased material costs and variations in the sales mix.
 
    Research and development expenses increased by 19% in Andros' Fiscal 1995
over Andros' Fiscal 1994 due primarily to research and development expenses for
the MAP 4 project at Scitec. Excluding Scitec, research and development expenses
decreased 1% compared to Andros' Fiscal 1994 due to tighter control over
expenses in Andros' Fiscal 1995.
 
                                       69
<PAGE>
    Marketing, general and administrative expenses were up 16% in Andros' Fiscal
1995 over Andros' Fiscal 1994. This increase primarily related to operations at
Scitec, including a one-time charge of $850,000 related to consolidation and
streamlining of operations. Excluding Scitec, marketing, general and
administrative expenses decreased 1% in Andros' Fiscal 1995 over Andros' Fiscal
1994.
 
    Interest and other income increased by 30% to $1,354,900 mainly as a result
of higher interest rates on cash and cash equivalents and short-term investment
balances.
 
    The effective rate for the income tax provision for Andros' Fiscal 1995 of
15.2% was significantly below the combined federal and state statutory rate,
primarily due to tax benefits attributable to Andros' foreign sales corporation,
research and development credits, and an adjustment of prior years' taxes.
 
    Net income for Andros' Fiscal 1995 decreased 64% from Andros' Fiscal 1994 to
$2,865,500 mainly due to the decrease in sales relative to fixed costs as well
as the increases in marketing, general and administrative expenses. As a result,
earnings per share decreased 65% for Andros' Fiscal 1995 from Andros' Fiscal
1994.
 
    For information regarding foreign operations and export sales see "Andros
Business--Sales, Marketing and Customers" and Note 8 to the consolidated
financial statements of Andros Inc. for Andros' Fiscal 1995 and Andros' Fiscal
1994.
 
FISCAL YEAR ENDED JULY 31, 1994 COMPARED TO FISCAL YEAR ENDED JULY 25, 1993
 
    On December 28, 1993, Andros acquired Scitec in a transaction accounted for
as a purchase. Accordingly, Andros' financial results include the results of
operations of Scitec commencing on the date of acquisition. In the approximately
seven months ended July 31, 1994, Scitec's sales were $3,026,700, cost of sales
were $1,223,800, research and development expense was $269,000 and marketing,
general and administrative expense was $1,325,000. The discussion of Andros'
Fiscal 1994 results of operations compared to the fiscal year ended July 25,
1993 ("Andros' Fiscal 1993") amounts below excludes Scitec where appropriate.
 
    Andros' Fiscal 1994 sales of $54,715,000 (excluding Scitec) were 38% higher
than Andros' Fiscal 1993 sales. Automotive product sales and service revenues
were up 30% to a record $39,768,900 and represented 69% of total sales.
International automotive product sales were up 22% to $26,963,000 mainly due to
shipments resulting from the German vehicle inspection program. U.S. automotive
product sales increased by 68% over Andros' Fiscal 1993 to $9,726,400 due, in
part, to a consolidation in the industry which increased Andros' market share,
and also due to shipments of higher value products.
 
    Andros' worldwide medical product sales and service revenues were up 62% to
$14,946,100 in Andros' Fiscal 1994, representing 26% of total sales. Increases
in medical product sales were experienced equally in both U.S. and European
markets. Most of the overall increase was related to sales of the Model 4610
Multi-Gas Anesthesia Monitor Analyzer, a product introduced in Andros' Fiscal
1993 as an enhanced version of an earlier model.
 
    Automotive and medical parts and service revenue increased 42% to $5,637,700
over Andros' Fiscal 1993. Substantially all of this revenue relates to
international markets and corresponds to the increase in the number of installed
units needing maintenance.
 
    Gross margins in Andros' Fiscal 1994 decreased to 41% from 43% in Andros'
Fiscal 1993 mainly due to variations in the sales mix, particularly, an
increased proportion of sales of international automotive and medical products
which generally have lower margins than corresponding U.S. products.
 
    Research and development expense increased by 22% to $4,297,300 over Andros'
Fiscal 1993 (including Scitec) representing 7% of sales. This increase reflected
significant design efforts on new products at Andros as well as increases
resulting from the acquisition of Scitec.
 
    Marketing, general and administrative expense increased 57% over Andros'
Fiscal 1993 to $8,765,800 principally due to inclusion of Scitec expenses,
amortization of Scitec goodwill, increased customer service expenses related to
increases in sales and professional fees related to various acquisition
activities. These
 
                                       70
<PAGE>
expenses increased as a percentage of sales from 14% to 15% over Andros' Fiscal
1993 for the reasons discussed above. Excluding Scitec expenses (which were not
included in Andros' Fiscal 1993 amounts), marketing, general and administrative
expenses increased 33% over Andros' Fiscal 1993 amounts and were 14% of sales
(exclusive of Scitec sales).
 
    Interest and other income increased by 16% to $1,040,300 mainly due to
interest earned on larger cash and cash equivalents and short-term investment
balances.
 
    The effective rate for the income tax provision for Andros' Fiscal 1994 of
32.8% was significantly below the combined federal and state statutory rate,
primarily due to tax benefits attributable to Andros's foreign sales
corporation.
 
    Net income increased 37% over Andros' Fiscal 1993 to $8,019,000,
representing a 14% return on sales.
 
RISKS ASSOCIATED WITH THE ANDROS BUSINESS
 
    Set forth below are some of the material risks associated with Andros'
business and operations:
 
    (i) The industry in which Andros competes, as well as the markets that it
serves, may be characterized by cyclical market patterns as a consequence of,
among other things, business cycles, regulatory changes or general economic
conditions affecting the timing of orders from major customers. Substantial
variations in the operations of Andros' customers or in the demand for their
products has in the past and may in the future cause substantial variations in
sales and profitability from quarter to quarter. In addition, demand for Andros'
automotive and spectrum analysis instrumentation may be substantially affected
by the enactment, timing, extent and severity of state, federal and foreign laws
governing inspection of automotive emissions and levels of lead contaminants.
Andros has experienced fluctuations in sales of such products as well as demand
for particular product enhancements as a result of actual or perceived changes
in regulatory requirements. Legislation or regulations resulting in stricter
enforcement of, or more stringent specifications for, testing of automotive
emissions has resulted in periodic increases in sales and the development of
enhanced new products. Conversely, decreases in sales have resulted, and may
result in the future, from actual or perceived delays in or weakening of
enforcement standards. Andros expects such fluctuations to continue in the
future. In particular, during Andros' Fiscal 1995, a weakening of regulation of
automotive emissions in a number of states resulted in a significant decline in
the rate of growth of U.S. sales of automotive gas analyzer products.
 
    (ii) Andros is also subject to various environmental laws and regulations
both in the U.S. and abroad. The operations of Andros, like those of other
companies in the industries in which Andros competes, involve the use of
substances regulated under environmental laws. In particular, products
manufactured by Andros' Scitec subsidiary contain various radioactive materials.
The risk of accidental overexposure, contamination or injury from the handling
by customers, employees and others of these materials or related problems cannot
be eliminated completely. While Andros maintains insurance, there can be no
assurance that such insurance will provide adequate coverage against potential
liability or that Andros will be able to maintain or obtain additional insurance
on acceptable terms. In the event of an accident, Andros could be held liable
for any damages that result and any such liability could have a material adverse
effect on Andros' financial position or results of operations.
 
    (iii) The fields of NDIR gas analyzer instrumentation and XRF technology are
covered by many issued patents and patent applications. If Andros' products are
determined to use technology, processes or other subject matter that is claimed
under other existing U.S. or foreign patents, or if other companies obtain
patents claiming subject matter utilized by Andros, such companies may bring
infringement actions against Andros. Andros may not have the resources necessary
to challenge successfully the validity of such patents or withstand claims of
infringement in cases where Andros' position has merit. Even if Andros were to
be successful in prevailing in such actions, the cost of such litigation could
have a material adverse effect on Andros' results of operations. An adverse
outcome could subject Andros to significant liabilities to third parties,
require disputed rights to be licensed or require Andros to cease using such
technology.
 
                                       71
<PAGE>
There can be no assurance that Andros will be able to obtain such licenses or
that such licenses, if available, can be obtained on commercially reasonable
terms.
 
    (iv) Andros also relies on trade secret protection for its confidential and
proprietary information. There can be no assurance that others will not
independently develop substantially equivalent proprietary technologies or
otherwise gain access to Andros' trade secrets or disclose such technologies, or
that Andros can meaningfully protect its trade secrets.
 
    (v) The products of Andros' medical device manufacturer customers into which
Andros' devices are incorporated are "medical devices" within the meaning of a
1976 amendment to the Federal Food, Drug and Cosmetics Act. Under the amendment,
a manufacturer must obtain approval by the FDA of a new medical device before it
can be marketed in the United States. The approval process requires that the
safety and efficacy of such devices be demonstrated by the manufacturer to the
FDA. Under certain circumstances, the cost of obtaining such premarketing
approval may be high and the process lengthy. All of the products currently
marketed domestically by Andros and products incorporating Andros' devices
marketed by Andros' customers requiring pre-marketing approval from the FDA have
been so approved.
 
    Following regulatory approval, commercially marketed products, as well as
the manufacturer and manufacturing facility, are subject to periodic review and
inspections. In the event of a discovery of previously unknown problems with a
product of Andros or a product of its customers containing Andros' devices, then
restrictions on the product, Andros or the customer, including recalls (which
could require costly redesign or reconfiguration of Andros' product) or even
withdrawal of the product from the market could result, any of which could have
a material adverse effect on Andros.
 
    (vi) Products under development may be subject to delays due to, among other
things, engineering, regulatory or production problems. There can be no
assurance that Andros will not experience difficulties that could delay or
prevent the successful development, introduction and marketing of new products
or product enhancements, or that any new products or enhancements introduced
would adequately meet the requirements of the marketplace or otherwise achieve
market acceptance. If Andros were unable, for technological or other reasons, to
develop and introduce new products in a timely manner in response to changing
market environments, governmental regulations or customer requirements, there
would be a material adverse effect on Andros' results of operations.
 
    (vii) The process for licensing and registration of Scitec's products is
complex, and there can be no assurance that Scitec's activities and instruments
will continue to obtain or maintain appropriate regulatory licenses and
registration. In addition, regulations in some states require that instruments
be sold or rented only to customers licensed to operate the instruments by the
appropriate state agencies.
 
    (viii) While Andros has not experienced a material product liability claim
and also maintains product liability insurance, there can be no assurance that
it will be able to maintain such insurance or obtain additional insurance on
acceptable terms, that insurance will provide adequate coverage against
potential product liability, or that Andros will not be subject to a claim that
could otherwise have a material adverse effect on Andros' financial position or
results of operations.

                                ANDROS BUSINESS
 
GENERAL
 
    Andros designs, manufactures and markets NDIR gas analyzers and sub-systems
and other sensor instrumentation for medical, automotive and environmental
applications. Andros markets its NDIR products on a worldwide basis to many of
the leading OEMs of medical respiratory monitoring and automotive diagnostic
equipment including Hewlett-Packard Co., Siemens Medical Systems, Inc., Colin
Medical Instruments Corporation, SPX Corp. (Automotive Diagnostics and OTC
Corp.), Snap-on Tools Incorporated, Technotest S.R.L., Sagem Souriau Systems,
Grundig Professional Electronic GmbH, Computer Aided Services, Inc., Kontron
Instruments Ltd., AVL List GmbH and Actron Manufacturing Co.
 
    In general, these companies incorporate Andros' products into their own
systems which they in turn sell to end-users. Andros' NDIR products detect the
presence and measure the concentration of a variety of multi-component gas
streams. In medical applications, Andros' NDIR systems are used to detect and
measure the level of anesthetic agents, carbon dioxide, oxygen and nitrous oxide
in the inspired and expired breath of patients in operating room, recovery room
and intensive care unit environments. In automotive applications, Andros' NDIR
systems are used to detect and measure the level of carbon monoxide, carbon
dioxide, hydrocarbons, oxygen and oxides of nitrogen in automobile exhaust. In
December 1993, Andros Inc. expanded its product line through the acquisition of
Scitec, which designs, manufactures and sells spectrum analysis instruments that
analyze the elemental composition of a material in its natural location and
condition using XRF technology. These products are sold to end users principally
for detection of lead in paint.
 
HISTORY
 
    Andros Inc. was formed in 1968 to design and develop scientific instruments
under contract to United States government agencies, and has concentrated on the
development of instruments utilizing NDIR gas analyzer technology. In 1976,
Andros Inc. adopted a strategy of commercializing its NDIR gas analyzer
technology by producing products for and selling to instrumentation
manufacturers on an OEM basis. Andros Inc. initially concentrated its efforts on
the design, manufacture and sale of NDIR gas analyzers used in equipment for
diagnostic engine tune-ups to improve the fuel efficiency of motor vehicles. The
adoption by the U.S. government of the 1977 and 1990 amendments to the Clean Air
Act of 1970, and the subsequent enactment of laws by many states and countries
which require regular inspection and maintenance of automotive emissions,
created additional demand for NDIR gas analyzers for the measurement and
analysis of gases in automotive emissions. Several leading manufacturers of
automotive test equipment have designed their equipment to incorporate Andros'
products. In addition, in the last few years, several Western European nations
have adopted active programs to improve air quality by requiring more frequent
and more stringent automotive emissions testing. Moreover, several Latin
American and Southeast Asian nations are initiating automotive emissions control
programs.
 
    In 1980, Andros Inc. began to expand the applications for its NDIR gas
analyzer products by developing products for the medical market. Andros' medical
gas analyzer products are incorporated into devices for the analysis of the
inspired and expired breath of patients undergoing general anesthesia, post-
surgical recovery and intensive care. Today, Andros produces fully-functional
anesthesia monitors that are one of many modules that make up the
multi-parameter medical monitors sold by medical equipment manufacturers
including Hewlett Packard and Siemens.
 
    ACQUISITION OF SCITEC CORPORATION.  In December 1993, Andros Inc. acquired
Scitec, headquartered in Kennewick, Washington, for $7,000,000 in cash and the
assumption of liabilities aggregating $1,171,300. Founded in 1986, Scitec
designs, manufactures and sells portable spectrum analysis instruments that use
XRF technology to analyze the elemental composition of materials in situ and in
real time. Scitec's products are typically used in industries such as
environmental testing, mining and exploration. The fastest growing market for
the use of Scitec's products is the detection of lead in paint, whose growth is
being driven by the recent enactment and enforcement of Title X of the Housing
and Community Development Act of 1992 which amended the Toxic Substances Control
Act.
 
                                       73
<PAGE>
    ACQUISITION BY GENSTAR.  On March 26, 1996, Andros Acquisition acquired 58%
of the outstanding shares of Andros Inc. through a public tender offer for
$18.00 per share. As of May 14, 1996, Andros acquired substantially all of the
remaining Andros Inc. shares outstanding which were not already purchased on
March 26, 1996 for $18.00 per share as a result of the merger of Acquisition
into Andros Inc.
 
MEDICAL INSTRUMENTATION
 
    Andros Inc. entered the medical products field in 1980 with the introduction
of a gas analyzer for the measurement of carbon dioxide and nitrous oxide in
human breath for use principally in hospital operating rooms, post-surgical
recovery rooms and Intensive Care Units ("ICUs"). In the operating room,
real-time knowledge of the components and concentrations of gases inhaled and
exhaled by the patient is vital to the assurance of patient safety during the
time the patient is anesthetized. Monitoring the amount of anesthetic agents,
carbon dioxide, oxygen and nitrous oxide entering and leaving the patient can
help the anesthesiologist ensure a patient is adequately ventilated, which is
critical to ensuring the delivery of oxygen to the brain and other vital organs.
In addition, this information helps the anesthesiologist minimize the time a
patient is anesthetized, reducing the risk of complications and the time spent
in post-operative recovery and thereby increasing the quality of patient care
and reducing the over-all cost of patient care, a driving force in the health
care industry today.
 
    Andros develops and sells various gas analyzers for medical monitoring
purposes. Andros is a major supplier of medical gas analyzers to the Medical
Division of Hewlett-Packard Co.; Siemens Medical Systems, Inc.; Dragerwerk AG
and its affiliate, North American Drager; Colin Medical Instruments Corporation;
Kontron Instruments Ltd.; Actron Manufacturing Company; and Datascope
Corporation.
 
    The following is a description of Andros' medical gas analyzer products:
 
    MULTI-GAS ANESTHESIA MONITOR.  In Andros' fiscal year ended July 28, 1991,
Andros introduced its Model 4610 Multi-Gas Anesthesia Monitor Analyzer ("4610"),
which permits continuous, simultaneous monitoring of anesthetic agents, carbon
dioxide and nitrous oxide on a breath-by-breath basis. Prior to the introduction
of the 4610, physicians were able to monitor both the gases and anesthetic
agents in a patient's breath through the use of either a single mass
spectrometer or a number of separate NDIR gas analyzers. Andros believes that,
although mass spectrometers can measure more gases than the 4610, they cannot
provide continuous monitoring as cost effectively as the 4610. Andros' 4640
agent identifying module can be integrated with the 4610 to provide automatic
agent identification for sophisticated monitor applications.
 
    CAPNOMETERS.  Capnometers monitor the respiratory functions of patients by
measuring the levels of end-tidal carbon dioxide expelled from their lungs.
"End-tidal" refers to the air expelled last in the patient's breathing cycle,
which comes from an area of the lungs closest to the blood vessels and,
therefore, permits a highly accurate measure of pulmonary gas exchange. In 1980,
Andros Inc. introduced its 400 Series gas analyzer which measures the
concentration of carbon dioxide in a patient's breath. This product also
measures the concentration of nitrous oxide (an analgesic) which, together with
a patented Andros process for automatic compensation for the effect of nitrous
oxide on carbon dioxide measurements, permits more accurate carbon dioxide
measurements. In Andros' Fiscal 1994, Andros Inc. introduced the Model 4210
On-Airway Carbon Dioxide Analyzer. This product is designed for breath-by-breath
monitoring in a variety of hospital settings outside the operating room, such as
ICU, emergency care and during transport.
 
    4700 SERIES ANESTHESIA GAS MONITORING SUB-SYSTEMS.  In Andros' Fiscal 1995,
Andros Inc. began delivery of its 4700 series of custom OEM anesthesia gas
monitoring sub-systems, incorporating measurement and identification of
anesthetic agents, carbon dioxide, nitrous oxide, oxygen, patient breath rate,
and elapsed time since the last detected breath, all on a breath-by-breath
basis. In addition to gas concentration analyzers, the 4700 includes complete
sample delivery and power modules packaged per OEM customer requirements. Andros
believes that the 4700 offers unique value and opportunity to both large and
small OEM medical device manufacturers addressing the instrumentation
requirement of the operating room.
 
                                       74
<PAGE>
    Because Andros' medical instrumentation products are sold on an OEM basis,
Andros is not required to obtain approval of the FDA of its medical devices
prior to sale by Andros. However, the products of Andros' customers into which
Andros' devices are incorporated are subject to pre-market clearance or other
regulation by the FDA and foreign governmental authorities. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations of
Andros--Risks Associated with the Andros Business."
 
    Revenue from sales and service of medical gas analyzer products was
$14,971,500 for the twelve months ended July 31, 1996, $13,359,000 in Andros'
Fiscal 1995, $14,946,100 in Andros' Fiscal 1994 and $9,230,200 in Andros' Fiscal
1993.
 
AUTOMOTIVE GAS ANALYZERS
 
    Andros is a leading worldwide OEM supplier of NDIR automotive gas analyzers.
These products are incorporated into automotive diagnostic equipment sold to
automotive repair shops, car dealerships and neighborhood garages for engine
tune-ups and for exhaust inspections. Andros is a major supplier of NDIR
automotive gas analyzers to various affiliates of SPX Corporation, including
Automotive Diagnostics and OTC Corporation; Crypton Wellman Ltd. (United
Kingdom); Sagem Souriau Systems (France); Snap-on Tools Corporation and its
subsidiary, Sun Electric Corporation; Tecnotest S.r.l. (Italy); Grundig
Professional Electronic GmbH, Computer Aided Services, Inc.; AVL List GmbH; and
others. Demand for Andros' automotive products continues to be driven in large
part by the increasing use of engine diagnostic equipment resulting from the
increasing sophistication of automobile engines and the adoption and amendment
of automotive emissions laws by various jurisdictions.
 
    The following is a description of Andros' principal automotive gas analyzer
product lines:
 
    200 SERIES.  Andros' 200 Series gas analyzer was first introduced in 1977
and is still being sold today in significant quantities. The 200 Series is a
high-performance analyzer utilizing analog circuitry which measures
concentrations of carbon dioxide, carbon monoxide and hydrocarbon gases. The 200
Series is sold in a three-gas configuration and is incorporated into products
used either for government-mandated automobile emission inspection programs or
for engine tune-ups to improve the fuel efficiency of motor vehicles.
 
    5000 SERIES.  Andros also sells a lower priced, medium-performance digital
electronic gas analyzer for automotive emissions inspection in non-U.S. programs
which are materially less stringent in their instrumentation requirements than
those for which the 200 Series is used. Like the 200 Series, the 5000 Series
analyzer can measure concentrations of carbon dioxide, carbon monoxide and
hydrocarbon gases. The 5000 Series is sold in one-gas, two-gas or three-gas
configurations. The 5000 Series meets only a limited number of worldwide
performance specifications and is sold primarily in Western Europe.
 
    6000 SERIES.  Andros' 6000 Series four-gas analyzer meets all current U.S.
emission analyzer specifications, including the 1990 California specifications,
and the most stringent European standards, the OIML-Class I. The 6000 Series
incorporates advanced digital technology and comes in a five-gas configuration
which uses chemical sensor technology to measure oxides of nitrogen. Andros
offers the 6000 Series in a variety of configurations ranging from a 'bare
bones' optical bench to a fully configured shelf sub-system incorporating a
pneumatic pump and filter module and power supply in addition to the optical
bench.
 
    7000 SERIES.  The Model 7110 Digital Opacimeter Subsystem, otherwise known
as the Smoke Meter, provides Andros' OEM automotive test equipment customers
with an opacity measuring analyzer for diesel engines. The Smoke Meter
incorporates visible light absorption technology, an addition to Andros'
technology base. The Smoke Meter is sold primarily in Western Europe.
 
    MICROBENCH.  The Microbench represents a significant technological advance
over Andros' previous generation of automotive products. By incorporating all of
the functionality of a fully configured 6000 Series 5-gas shelf (including the
pneumatics systems and power supply) into a form factor one-fifth the size,
one-tenth the weight and requiring one-twentieth the power, management believes
the Microbench
 
                                       75
<PAGE>
will significantly change the way automotive analyzers are marketed. Whereas the
prior generation of analyzers was incorporated into refrigerator size engine
analyzers, the Microbench will be incorporated into a truly hand-held, battery
operated diagnostic instrument. The lower cost and smaller size of the
Microbench is anticipated to broaden the addressable market for automotive gas
analysis equipment from one unit per garage or garage bay to one unit per
automotive technician. The advanced technology used in the Microbench was
derived from technologies originally developed for Andros' medical products,
evidencing the technology sharing by Andros' two core product development
programs.
 
    In many jurisdictions, the diagnostic products sold by Andros' OEM customers
must be certified by regulatory or quasi-regulatory agencies before they can be
used in emission inspection programs. Andros' products must meet certain
specifications to enable its customers' devices to achieve certification,
although the Andros devices are not themselves certified.
 
    Revenue from sales and service of automotive gas analyzers was $25,115,500
for the twelve months ended July 31, 1996, $26,509,300 in fiscal 1995,
$39,768,900 in fiscal 1994 and $30,493,300 in fiscal 1993.
 
SPECTRUM ANALYSIS INSTRUMENTATION
 
    Andros' Scitec subsidiary designs, manufactures and sells portable spectrum
analysis instrumentation designed to detect and measure selected elements in a
material in its natural location and condition using powerful k-shell XRF
technology. Scitec sells its products directly through a five person direct
sales force and through a network of four independent sales organizations with a
total of seven representatives throughout the United States.
 
    Scitec's current product line is used principally to detect the presence and
concentration of lead in paint. Historically lead has been added to house paints
and other paints because it helped paint dry faster and improved resistance to
weather. Today lead is classified as a toxic substance and is known to cause
adverse health effects in humans and the environment. Lead poisoning is
widespread among children affecting as many as three million children in the
United States under the age of seven. Deteriorating lead-based paint is believed
to be a leading cause of lead poisoning in children. In the residential housing
sector, the U.S. Department of Housing and Urban Development ("HUD") estimates
that there are 57 million privately owned and occupied homes built before 1980
(the use of lead-based paint in residential construction was banned in 1978)
that contain lead-based paint. Of those homes approximately 9.9 million are
occupied by children under the age of seven, the group most at risk to the
hazards of lead-based paint. In October 1992, the U.S. Congress enacted the
Housing and Community Development Act, to address the lead-based paint in the
nation's housing stock. Title X of that bill, the Residential Lead Based Paint
Hazard Reduction Act, provided a comprehensive national approach to dealing with
lead-based paint. The regulations implementing Title X which were approved in
April 1996 and are set to take effect beginning in September 1996 include among
other things provisions requiring the disclosure of any known lead-based paint
hazards upon sale of any residence, set standards for the inspection of
residences for lead-based paint hazards and require that a seller give a
potential buyer the opportunity to inspect a residence for the presence of lead
hazards.
 
    Scitec's primary product line includes:
 
    MAP SPECTRUM ANALYZER.  Scitec's metal analysis probe ("MAP") spectrum
analyzer is an automated system that employs XRF technology to detect and
measure the intensity and frequency of x-rays emitted by an irradiated sample.
The analyzer produces a graph, or "spectrum", depicting the energy of the
emitted radiation, which indicates the amount of lead present, whether it is
located on or below the surface of the paint and whether there are other
elements or possible contaminants in the paint. The MAP 4 is a portable, "full
spectrum" analyzer, capable of measuring both the K and L emission lines of lead
simultaneously in a wide range of field conditions. The basic MAP 4 system
includes a control console with 256K of memory, which is connected to a hand
scanner by a 10-foot cable, and is calibrated on typical substrates with the
U.S. Department of Housing and Urban Development lead-in-paint reference
standards. The radiation source is a 40 millicurie Cobalt 57 radio isotope.
Included with the console are
 
                                       76
<PAGE>
spectrum display, automatic substrate correction and automatic source decay time
correction software programs, as well as a carry pack, rechargeable batteries,
operator's manual and shipping case.
 
    Optional software packages include:
 
    Advanced Report Manager ("ARM") database software electronically records
test locations, field notes and measurement results and processes the
information to produce a comprehensive test report.
 
    AcuTransfer software allows data to be downloaded from the console to a
personal computer and checks during data transfer for indications of abnormal
field conditions, instrument malfunction or operator misuse.
 
    Hardware, software and training packages are sold in a total system as the
AcuData System. Additional memory capacity, additional calibration programs, and
a variety of accessories, such as telescoping poles and clamps, are also
available.
 
    Scitec is required to be licensed by the Washington State Department of
Health to conduct certain activities related to radioactive materials. That
agency conducts periodic reviews to ensure compliance with the safety and other
conditions of the license. In addition, instruments manufactured by Scitec
containing radioactive materials must be registered with the Washington State
Department of Health. Changes in activities or modifications to instruments
typically require that an amended license or registration be approved by the
applicable regulatory agency. Scitec's practice has been to require that all
customers be so licensed. Scitec also conducts training courses for employees
and customers.
 
    Andros' revenue from sales and service of spectrum analysis instruments was
$3,072,500 for the twelve months ended July 31, 1996, $2,885,100 in fiscal 1995
and $3,026,700 in fiscal 1994.
 
SALES, MARKETING AND CUSTOMERS
 
    Andros' products are sold primarily on an OEM basis. Scitec products are
sold by sales personnel and representatives primarily to end user customers in
the environmental testing and mining and exploration markets. Selling activities
consist principally of direct sales calls on customers and potential customers
by senior management, technical and sales personnel. In addition to its
Berkeley, California and Kennewick, Washington locations, Andros has independent
sales agents in Europe and Asia.
 
    To date, Andros' products have been sold primarily to manufacturers of
respiratory monitoring equipment or automotive diagnostic equipment. There are a
relatively small number of major manufacturers in these industries, particularly
in the automotive diagnostic equipment market, which has recently experienced a
consolidation. As a result, a significant portion of Andros' sales are to a
small number of customers. During the twelve months ended July 31, 1996, Andros'
13 largest customers accounted in the aggregate for more than 80% of sales. In
addition, three customers, Hewlett-Packard Co., SPX Corp. and Snap-on Tools
Incorporated, each accounted for more than 10% of total sales and aggregated 53%
of Andros' total sales. Although products of Andros' Scitec subsidiary are sold
to a broad range of end user customers in other markets, Andros anticipates that
it will continue to make a substantial portion of its sales to a limited number
of customers and, therefore, the loss of, or cancellation of orders by, any
major customer could have a material adverse effect on Andros' results of
operations. In addition, the timing of orders by major customers or decisions by
one or more major customers to cancel or defer purchases could lead to
substantial variability from quarter to quarter.
 
    In addition to domestic markets, Andros actively markets its products in
Western Europe and, to a growing extent, in the Far East and South America.
International sales include sales to foreign customers, and sales to domestic
customers for equipment produced by them for shipment overseas. Product sales to
customers outside of the United States accounted for approximately 60% of
Andros' total sales for the 12 months ended July 31, 1996. Andros' international
sales are denominated in U.S. dollars. Accordingly, decreases in the value of
foreign currency relative to the U.S. dollar could make Andros' products less
price-competitive. Foreign currency fluctuations have not had a material or
significant impact on Andros' results of operations historically since operating
expenses denominated in other than U.S. dollars have not
 
                                       77
<PAGE>
been material or significant. However, foreign operating expenses denominated in
foreign currencies are expected to increase as Andros' foreign operations grow,
and foreign currency fluctuations may, in the future, become more significant as
a result. International sales and operations may also be materially adversely
affected by changes in governmental regulations, the imposition of governmental
controls, export license requirements, restrictions on export of critical
technology, political and economic instability or conflicts, trade restrictions,
changes in tariffs and taxes, difficulties in staffing and managing
international operations, general economic conditions overseas, and other
matters generally affecting foreign operations.
 
RESEARCH AND DEVELOPMENT
 
    The market for NDIR gas analyzer instrumentation and spectrum analysis
instrumentation is characterized by rapid technological change. In the medical
monitoring market, Andros is focused on developing products with more
functionality. In the automotive instrumentation market, technological changes
are often required as a result of changes in government regulations which can
vary among countries. In addition, as Andros' existing products become more
mature and its existing markets more saturated, Andros' ability to develop new
products and technologies increases in importance. Andros' future success will
depend to a large extent on its ability to enhance its current products and to
develop and introduce, on a timely and cost-effective basis, new products that
keep pace with technological developments and address the evolving needs of its
customers.
 
    The principal focus of Andros' current research and development effort is to
develop new products for existing markets as well as enhancements to current
products. For example, in the medical market and the market for automotive
diagnostic equipment, Andros is working to develop, among other things, an
analyzer that measures additional gases. In the spectrum analysis market, Andros
continues to develop products based on XRF technology with a focus on the
hazardous waste market.
 
    The costs of producing, promoting and servicing new products are generally
greater than in the case of more mature products, which may also have higher
volumes. Further, as new products are introduced, such new products may render
obsolete or otherwise less marketable Andros' then current products that address
similar market needs, which could lead to inventory write-offs or otherwise have
a material adverse impact on Andros' results of operations.
 
    Andros spent an estimated amount of $4,602,900, $5,100,900, $4,297,300, and
$3,528,500 during the 12 months ended July 31, 1996 and in fiscal years 1995,
1994 and 1993, respectively, for Andros-sponsored research and development.
 
PRODUCTION AND SERVICE
 
    Andros has been ISO 9001 certified since September 1995. Andros'
manufacturing operations consist of purchasing, assembling and testing the
materials and components comprising its products. The principal materials and
components used in the production of Andros' gas analyzer products include NDIR
source devices, motors, optical band-pass filters, photodetectors, printed
circuit boards, and plastic and metal parts, all of which are purchased from
independent suppliers. In addition to many of the components identified above,
Scitec products require a radioactive source, acquisition and transportation of
which is monitored by government authorities and which requires appropriate
licensing and compliance with accountability procedures. Although most are
standard parts, certain items proprietary to Andros, such as source assemblies,
molded plastic parts, filters, printed circuit boards, and photodetectors, are
fabricated or assembled by independent vendors using Andros' production tooling
or pursuant to proprietary design specifications owned by Andros.
 
    Andros' facilities and documentation procedures for the manufacture of
medical products are required to conform to the FDA's Good Manufacturing
Practices ("GMP"). Domestic manufacturing facilities are subject to biennial FDA
inspections. Failure to maintain GMP status would have a material adverse effect
on Andros.
 
                                       78
<PAGE>
    Andros conducts manufacturing operations for all of its NDIR gas analyzer
products in its Berkeley, California, headquarters facility. Its spectrum
analysis instruments are manufactured at its Scitec subsidiary in Kennewick,
Washington.
 
    To date, Andros has received a significant proportion of its revenues from
upgrading or servicing customers' existing equipment. Andros performs most of
its service and repair work in its service facilities located in Berkeley,
California. Service of Scitec products is performed at the Scitec facility
located in Kennewick, Washington. Andros' warranties vary among products, but
may extend for periods up to three years, while products manufactured by Scitec
have warranties for up to five years. Scitec also offers a variety of training
courses to all customers as well as in-field technical support, measurement
validation and test certification services. Andros derives revenue from the sale
of replacement parts as well as from the sale of parts under license to
customers to manufacture Andros' products. Service and parts revenues were
$5,312,100 for the twelve months ended July 31, 1996, $6,909,100 in fiscal 1995,
$6,584,300 in fiscal 1994 and $3,959,600 in fiscal 1993. Revenues include
revenues of Scitec commencing in December 1993. These revenues are included in
the revenues disclosed in the discussion under "--Medical Instrumentation",
"--Automotive Gas Analyzers" and "--Spectrum Analysis Instrumentation" above.

    Stock.
 
COMPENSATION OF DIRECTORS
 
    The Company has a policy of paying its directors who are not employees of
the Company an annual fee of $2,500 plus $1,250 for each meeting of the Board of
Directors of the Company attended.
 
    Thomas M. Haythe, General Counsel and a director of the Company, is a member
of the law firm of Haythe & Curley, the Company's general counsel. It is
expected that Haythe & Curley will continue to render legal services to the
Company in the future.
 
COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
    The report of the Compensation Committee documents the Committee's policies
regarding executive officer compensation. The Company's philosophy and
objectives in setting compensation are (i) to offer levels of compensation which
are competitive with those offered by other companies in similar businesses;
(ii) to compensate executives based on each executive's level of responsibility
and contribution to the Company's business goals; (iii) to link compensation
with the Company's financial performance; and (iv) to align the interests of the
Company's executives with the interests of the Company's stockholders.
 
    BASE SALARY.  Base salary is determined by level of responsibility,
individual performance and Company performance, as well as by the need to
provide a competitive package that allows the Company to retain key executives.
After reviewing individual and Company performance and market studies on
salaries at other companies of similar size, the President makes recommendations
to the Compensation Committee concerning officers' salaries, other than his own.
The Compensation Committee reviews and, with any changes it deems appropriate,
approves these recommendations. Using the same review process, the Compensation
Committee makes decisions pertaining to the President's salary.
 
    EXECUTIVE BONUSES.  Executive bonuses provide the opportunity for executive
officers to earn additional compensation by achieving specific performance
goals. The Company will pay a percentage of each participant's annual base
salary as an annual bonus, provided the Company achieves specific performance
objectives. These objectives are established by the Board of Directors of the
Company at the beginning of each fiscal year in consultation with such executive
officers.
 
    STOCK OPTIONS.  The Company periodically grants stock options to its
executive officers and other key employees. The primary purpose of stock option
grants is to align the interests of the Company's executive officers more
closely with the interests of the Company's stockholders by offering the
executives an opportunity to benefit from increases in the market price of the
Novametrix Common Stock. Stock options provide long-term incentives that have
enabled the Company to attract and retain key employees by encouraging their
ownership of Novametrix Common Stock. The stock option plans are administered by
the Stock Option Committee of the Company's Board of Directors, which determines
the persons who are to receive options and the number of shares to be subject to
each option. In selecting individuals for
 
                                       83
<PAGE>
options and determining the terms thereof, the Stock Option Committee may take
into consideration any factors it deems relevant, including present and
potential contributions to the success of the Company.
 
    COMPENSATION OF EXECUTIVE OFFICERS.  The Company has an employment agreement
with William J. Lacourciere, President and Chief Executive Officer of the
Company. Pursuant to this agreement, the annual base salary of Mr. Lacourciere
is subject to cost of living increases and increases at the discretion of the
Company's Board of Directors based upon performance of the Company and
performance of the executive. For fiscal year 1995, the Company's Board of
Directors approved an increase of approximately 20% in the base salary payable
to Mr. Lacourciere. In addition, for fiscal years 1995 and 1996, the Company
granted Mr. Lacourciere bonuses of $25,000 and $15,000, respectively, based upon
individual performance and contribution to the growth of the Company. The salary
increase and the bonus awards were based on the continued increases in sales,
operating income, net income and earnings per share of the Company during fiscal
1994, 1995 and 1996.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    All executive officer compensation decisions have been made by the
Compensation Committee of the Company's Board of Directors. The Compensation
Committee reviews and makes recommendations regarding the compensation for
management and key employees of the Company, including salaries and bonuses. No
member of the Compensation Committee is an executive of the Company. The current
members of the Compensation Committee are Steven J. Shulman, Michael J. Needham
and Thomas M. Haythe. At the Effective Time, the Compensation Committee will be
composed of an equal number of the continuing members of the Board of Directors
of the Company and the members appointed by the Board of Directors of Andros.
For information concerning the proposed appointees of Andros to the Board of
Directors of the Company, see "Novametrix Management--Andros Designees to the

               OTHER MATTERS SET FORTH FOR ACTION AT THE MEETING
                 II.  APPROVAL OF 1996 LONG TERM INCENTIVE PLAN
 
    The Company's Board of Directors believes that attracting and retaining key
employees and directors of high quality is essential to the Company's growth and
success. The Company's Board of Directors also believes that important
advantages to the Company are gained by a comprehensive compensation program
which includes different types of incentives for motivating such individuals and
rewards for outstanding service. In this regard, stock options and other
stock-related awards have been and will continue to be an important element of
the Company's compensation program because such awards enable employees and
directors to acquire or increase their proprietary interest in the Company,
thereby promoting a close identity of interests between such individuals and the
Company's stockholders. Such awards also provide to employees and directors an
increased incentive to expend their maximum efforts for the success of the
Company's business.
 
    Accordingly, on April 29, 1996 the Company's Board of Directors adopted,
subject to stockholder approval at the Meeting, the Novametrix Medical Systems
Inc. 1996 Long Term Incentive Plan (the "Incentive Plan"). In authorizing grants
of a wide range of awards, including options, stock appreciation rights
("SARs"), restricted stock, performance awards and other stock-based awards, the
Incentive Plan is intended to give the Company greater flexibility to respond to
rapidly changing business, economic and regulatory requirements and conditions.
In addition, such flexibility will enhance the ability of the Company to link
closely compensation to performance. The Incentive Plan will not become
effective unless approved by the holders of a majority of the voting power of
the shares present or represented and voting thereon at the Meeting. The text of
the Incentive Plan is set forth in Appendix E hereto.
 
    The following discussion of the material features of the Incentive Plan is
qualified by reference to the text of the Incentive Plan set forth in Appendix E
hereto.
 
    SHARES SUBJECT TO THE PLAN.  Under the Incentive Plan, 750,000 shares of
Novametrix Common Stock will be available for issuance of awards. Shares
distributed under the Incentive Plan may be either newly issued shares or
treasury shares. If any shares subject to an Incentive Plan award are forfeited
or the award is settled in cash or otherwise terminates without a distribution
of shares, the shares subject to such award will again be available for awards
under the Incentive Plan. Thus, for example, if an award is voluntarily
surrendered in exchange for a new award, the shares that were subject to the
surrendered award would be available for the new award (or other awards) under
the Incentive Plan. The maximum number of shares of Novametrix Common Stock
which may be granted to any individual under the Incentive Plan in any two-year
period shall not exceed 100,000 shares, subject to the adjustments described in
the next paragraph.
 
    The Incentive Plan provides that, in the event of changes in the corporate
structure of the Company affecting the Novametrix Common Stock, the Stock Option
Committee may adjust (i) the number and kind of shares which may be issued in
connection with awards, (ii) the number and kind of shares issued or issuable in
respect of outstanding awards, and (iii) the exercise price, grant price, or
purchase price relating to any award, and the Stock Option Committee may also
provide for cash payments relating to awards. The Stock Option Committee may
also adjust performance conditions and other terms of awards in response to
these kinds of events or to changes in applicable laws, regulations or
accounting principles. The Incentive Plan provides that, in connection with any
merger or consolidation in which the Company is not the surviving corporation or
any sale or transfer by the Company of all or substantially all its assets or
any tender offer or exchange offer for or the acquisition, directly or
indirectly, by any person or group of all or a majority of the then outstanding
voting securities of the Company, all outstanding options under the Incentive
Plan will become exercisable in full on and after (i) 15 days prior to the
effective date of such merger, consolidation, sale, transfer or acquisition or
(ii) the date of commencement of such tender offer or exchange offer, as the
case may be.
 
    ELIGIBILITY.  Any employee, including any officer or employee-director, of
the Company and its subsidiaries or affiliated companies is eligible to receive
awards under the Incentive Plan. Directors of the Company who are not employees
are eligible for grants of stock options under the Incentive Plan.
 
                                       89
<PAGE>
    ADMINISTRATION.  The Incentive Plan will be administered by the Stock Option
Committee of the Company's Board of Directors. Subject to the terms and
conditions of the Incentive Plan, the Stock Option Committee is authorized to
designate participants who are employees, directors or consultants of the
Company and its subsidiaries and affiliated companies, determine the type and
number of awards to be granted, set terms and conditions of such awards,
prescribe forms of award agreements, interpret the Incentive Plan, specify rules
and regulations relating to the Incentive Plan, and make all other
determinations which may be necessary or advisable for the administration of the
Incentive Plan.
 
    The Incentive Plan provides that in the event that any member of the Stock
Option Committee is not a "disinterested person" as defined in Rule 16b-3 under
the Securities Exchange Act of 1934, as in effect at April 30, 1991, the maximum
number of shares of Novametrix Common Stock which may be subject to options
granted to all directors is 300,000 and the maximum number of shares of
Novametrix Common Stock which may be subject to options granted in any two-year
period to each employee-director is 100,000 and to each director who is not an
employee of the Company is 10,000.
 
    STOCK OPTIONS AND SARS.  The Stock Option Committee is authorized to grant
stock options, including both incentive stock options ("ISOs"), which can result
in potentially favorable tax treatment to the participant, and nonqualified
stock options, and also to grant SARs entitling the participant to receive the
excess of the fair market value of a share on the date of exercise or other
specified date over the grant price of the SAR. The exercise price per share of
Novametrix Common Stock subject to an option and the grant price of an SAR is
determined by the Stock Option Committee, provided that the exercise price may
not be less than the fair market value of the Novametrix Common Stock on the
date of grant. The term of each such option or SAR, the times at which each such
option or SAR shall be exercisable, and provisions requiring forfeiture of
unexercised options at or following termination of employment, generally will be
fixed by the Stock Option Committee, except no ISO or SAR relating thereto will
have a term exceeding ten years. Options may be exercised by payment of the
exercise price in cash, or in stock, outstanding awards or other property
(including notes or obligations to make payment on a deferred basis, such as
through "cashless exercises") having a fair market value equal to the exercise
price, as the Stock Option Committee may determine from time to time. Methods of
exercise and settlement and other terms of the SARs will be determined by the
Stock Option Committee.
 
    RESTRICTED STOCK.  The Incentive Plan also authorizes the Stock Option
Committee to grant restricted stock. Restricted stock is an award of shares
which may not be disposed of by participants and which may be forfeited in the
event of certain terminations of employment prior to the end of a restriction
period established by the Stock Option Committee. Such an award would entitle
the participant to all of the rights of a stockholder of the Company, including
the right to vote the shares and the right to receive any dividends thereon,
unless otherwise determined by the Stock Option Committee.
 
    PERFORMANCE AWARDS.  The Incentive Plan also authorizes the Stock Option
Committee to grant to eligible employees performance awards. A performance award
is an award which consists of a right (i) denominated or payable in cash,
Novametrix Common Stock, other securities or other property (including, without
limitation, restricted securities), and (ii) which shall confer on the holder
thereof rights valued as determined by the Stock Option Committee and payable
to, or exercisable by, the holder of the performance award upon the achievement
of such performance goals during such performance periods as the Stock Option
Committee shall establish. Subject to the terms of the Incentive Plan and any
applicable award agreement, performance goals to be achieved during any
performance period, the length of any performance period, the amount of any
performance award granted and the amount of any payment or transfer to be made
pursuant to any performance award will be determined by the Stock Option
Committee and by the other terms and conditions of any performance award.
 
    OTHER STOCK-BASED AWARDS.  In order to enable the Company to respond to
business, economic and regulatory developments, and to trends in executive
compensation practices, the Incentive Plan authorizes the Stock Option Committee
to grant awards that are denominated or payable in, valued in whole or in part
by reference to, or otherwise based on or related to Novametrix Common Stock.
The Stock Option Committee determines the terms and conditions of such awards,
including consideration to be paid to
 
                                       90
<PAGE>
exercise awards in the nature of purchase rights, the period during which awards
will be outstanding, and forfeiture conditions and restrictions on awards.
 
    OTHER TERMS OF AWARDS.  The flexible terms of the Incentive Plan will permit
the Stock Option Committee to impose performance conditions with respect to any
award. Such conditions may require that an award be forfeited, in whole or in
part, if performance objectives are not met, or require that the time of
exercisability or settlement of an award be linked to achievement of performance
conditions.
 
    No awards may be granted under the Incentive Plan after June 30, 2006.
 
    Awards may be settled in cash, stock, other awards or other property, in the
discretion of the Stock Option Committee. The Stock Option Committee may
condition the payment of an award on the withholding of taxes and may provide
that a portion of the Novametrix Common Stock or other property to be
distributed will be withheld (or previously acquired Novametrix Common Stock or
other property surrendered by the participant) to satisfy withholding and other
tax obligations. Awards granted under the Incentive Plan may not be pledged or
otherwise encumbered and are not transferable except by will or by the laws of
descent and distribution to a guardian or legal representative designated to
exercise such person's rights and receive distributions under the Incentive Plan
upon such person's death, or otherwise if permitted under Rule 16b-3 and by the
Stock Option Committee.
 
    Awards under the Incentive Plan are generally granted for no consideration
other than services. The Stock Option Committee may, however, grant awards alone
or in addition to, in tandem with or in substitution for any other award under
the Incentive Plan, other awards under other Company plans, or other rights to
payment from the Company. Awards granted in addition to or in tandem with other
awards may be granted either at the same time or at different times. If an award
is granted in substitution for another award, the participant must surrender
such other award in consideration for the grant of the new award.
 
    The Novametrix Board may amend, modify or terminate the Incentive Plan at
any time provided that, unless required by law, (i) the number of shares of
Novametrix Common Stock available under the Incentive Plan may not be amended
without stockholder approval (subject to certain provisions relating to
adjustment as discussed above) and (ii) no amendment or termination of the
Incentive Plan may, without a participant's consent, adversely affect any rights
already accrued under the Incentive Plan by the participant. In addition, no
amendment or modification shall, unless previously approved by the stockholders
(where such approval is necessary to satisfy then applicable requirements of
federal securities laws, the Code, or rules of any stock exchange on which the
Novametrix Common Stock is listed) (i) in any manner affect the eligibility
requirements of the Incentive Plan, (ii) increase the number of shares of
Novametrix Common Stock subject to any option, (iii) change the purchase price
of the shares of Novametrix Common Stock subject to any option, (iv) extend the
period during which awards may be granted under the Incentive Plan, or (v)
materially increase the benefits to participants under the Incentive Plan.
 
    Unless earlier terminated by the Company's Board of Directors, the Incentive
Plan will terminate when no shares remain available for issuance and the Company
has no further obligation with respect to any outstanding award.
 
    FEDERAL INCOME TAX IMPLICATIONS OF THE PLAN.  The following description
summarizes the material federal income tax consequences arising with respect to
the issuance and exercise of awards granted under the Incentive Plan. The grant
of an option or SAR (including a stock-based award in the nature of a purchase
right) will create no tax consequences for the participant or the Company. A
participant will not have taxable income upon exercising an ISO (except that the
alternative minimum tax may apply) and the Company will receive no deduction at
that time. Upon exercising an option other than an ISO (including a stock-based
award in the nature of a purchase right), the participant must generally
recognize ordinary income equal to the difference between the exercise price and
fair market value of the freely transferable and nonforfeitable Novametrix
Common Stock acquired on the date of exercise, and upon exercising an SAR, the
participant must generally recognize ordinary income equal to the cash or the
fair market value of the freely transferable and nonforfeitable Novametrix
Common Stock received. In each case, the
 
                                       91
<PAGE>
Company will be entitled to a deduction equal to the amount recognized as
ordinary income by the participant.
 
    A participant's disposition of shares acquired upon the exercise of an
option, SAR or other stock-based award in the nature of a purchase right
generally will result in short-term or long-term capital gain or loss measured
by the difference between the sale price and the participant's tax basis in such
shares (or the exercise price of the option in the case of shares acquired by
exercise of an ISO and held for the applicable ISO holding periods). Generally,
there will be no tax consequences to the Company in connection with a
disposition of shares acquired under an option or other award, except that the
Company will be entitled to a deduction (and the participant will recognize
ordinary taxable income) if shares acquired upon exercise of an ISO are disposed
of before the applicable ISO holding periods have been satisfied.
 
    With respect to other awards granted under the Incentive Plan that may be
settled either in cash or in Novametrix Common Stock or other property that is
either not restricted as to transferability or not subject to a substantial risk
of forfeiture, the participant must generally recognize ordinary income equal to
the cash or the fair market value of Novametrix Common Stock or other property
received. The Company will be entitled to a deduction for the same amount. With
respect to awards involving stock or other property that is restricted as to
transferability and subject to a substantial risk of forfeiture, the participant
must generally recognize ordinary income equal to the fair market value of the
shares or other property received at the first time the shares or other property
become transferable or not subject to a substantial risk of forfeiture,
whichever occurs earlier. The Company will be entitled to a deduction in an
amount equal to the ordinary income recognized by the participant. A participant
may elect under Section 83(b) of the Code to be taxed at the time of receipt of
shares or other property rather than upon lapse of restrictions on
transferability or the substantial risk of forfeiture, but if the participant
subsequently forfeits such shares or property he would not be entitled to any
tax deduction, including as a capital loss, for the value of the shares or
property on which he previously paid tax. Such election must be made and filed
with the Internal Revenue Service within 30 days of the receipt of the shares or
other property.
 
    Section 162(m) of the Code limits deductibility of certain compensation for
each of the Chief Executive Officer of the Company and the additional four
executive officers who are highest paid and employed at year end to $1 million
per year, effective for tax years beginning on or after January 1, 1994. The
Company anticipates that action will be taken with respect to awards under the
Incentive Plan to ensure deductibility.
 
    The Stock Option Committee may condition the payment of an award on the
withholding of taxes and may provide that a portion of the stock or other
property to be distributed will be withheld (or previously acquired stock or
other property surrendered by the participant) to satisfy withholding and other
tax obligations.
 
    The foregoing summarizes the material federal income tax consequences
arising with respect to the issuance and exercise of awards granted under the
Incentive Plan. Different tax rules may apply with respect to participants who
are subject to Section 16 of the Securities Exchange Act of 1934, when they
acquire stock in a transaction deemed to be a nonexempt purchase under that
statute or within six months of an exempt grant of a derivative security under
the Incentive Plan. This summary does not address the effects of other federal
taxes or taxes imposed under state, local or foreign tax laws.
 
    The Board of Directors of the Company recommends that the Company's
stockholders vote FOR approval of the Incentive Plan. It is the intention of the
persons named in the accompanying form of Proxy to vote the shares represented
thereby in favor of such approval unless otherwise instructed in such Proxy.

                      III.  ELECTION OF CLASS A DIRECTORS
 
    The Company's Certificate of Incorporation provides for the division of the
Company's Board of Directors into three classes. The Class A directors and the
nominees for election identified below are Michael J. Needham and Joseph A.
Vincent, the Class B directors are Photios T. Paulson and Steven J. Shulman, and
the Class C directors are Thomas M. Haythe and William J. Lacourciere. The
stockholders have elected each class to serve for a full term of three years. If
the number of directors is increased, the increase will be apportioned among the
classes so as to make all classes as nearly equal in number as possible.
 
    Two Class A directors will be elected at the Meeting to serve for three
years and until their respective successors shall have been elected and
qualified. The Class B directors will be elected at the 1997 Annual Meeting and
the Class C directors will be elected at the 1998 Annual Meeting. It is the
intention of each of the persons named in the accompanying form of Proxy to vote
the shares represented thereby in favor of the nominees for Class A director
named below unless otherwise instructed in such Proxy. In case either one of the
nominees is unable or declines to serve, such persons reserve the right to vote
the shares represented by such Proxy for another person duly nominated by the
Company's Board of Directors in such nominee's stead. The Company's Board of
Directors has no reason to believe that either of the nominees, Michael J.
Needham and Joseph A. Vincent, will be unable or will decline to serve. The
nominees are each presently serving as Class A directors of the Company. At the
Effective Time of the Merger, the Board will be increased in size and new
members will be elected by the Novametrix Board as more fully described under
"The Merger Management of Novametrix Following the Merger".
 
    Certain information concerning the six present directors of the Company
(including the two nominees as Class A directors) is set forth herein under
"Novametrix Management".
 
    Information concerning the right of certain stockholders of the Company to
elect directors to the Board of Directors is set forth below.
 
    At the Effective Time, the Board of Directors and each committee thereof
will be reconfigured as described under "The Merger--Management of Novametrix
Following the Merger". For information as to the persons who are expected to be
appointed directors of the Company by Andros, see "Novametrix Management--Andros
Designees to the Novametrix Board".
 
    Effective May 20, 1996, Steven J. Shulman resigned as a Class A director of
the Company and was elected as a Class B director, to serve until the next
election of Class B directors or until his successor has been duly elected and
qualified. This change was made so as to eliminate the unequal distribution of
directors among classes which had resulted from prior director resignations and
to conform to the requirements of the Company's Amended and Restated Certificate
of Incorporation, which calls for three classes of Directors which are equal in
size. During Fiscal 1996, the Board of Directors of the Company met four times.
 
    During the fiscal year ended April 28, 1996, the Novametrix Board had a
Stock Option Committee, whose members were Messrs. Shulman, Haythe, Needham and
Paulson, a Compensation Committee, whose members were Messrs. Shulman, Haythe,
Needham and Paulson, and an Audit Committee, whose members were Messrs. Shulman
and Haythe. The Board of Directors of the Company does not have a Nominating
Committee.
 
    The Stock Option Committee administers the Company's stock option plans, and
its Employee Stock Purchase Plan. The Compensation Committee makes
recommendations to the Board of Directors of the Company regarding compensation
and other benefits to be paid to key employees of the Company. The Audit
Committee is authorized to review the results of the auditors' examinations and
to make recommendations with respect to accounting practices and procedures and
internal controls. The Audit Committee, the Stock Option Committee and the
Compensation Committee each met one time during the past fiscal year. All of the
directors other than Messrs. Needham and Shulman attended at least 75% of the
meetings of the Novametrix Board and meetings of any committee of the Novametrix
Board on which such directors served.
 
                                       93
<PAGE>
    The directors and officers of the Company, other than Messrs. Haythe,
Needham, Paulson and Shulman, are active in its business on a day-to-day basis.
No family relationships exist among any of the directors and officers of the
Company.
 
    On August 29, 1991, the Company issued an aggregate of 120,000 shares of
Series B Preferred Stock to certain investors, of which 100,000 shares are
currently outstanding. In addition to their right to vote with the holders of
shares of Novametrix Common Stock on all matters to be voted on at the Meeting,
the holders of record of the shares of Series B Preferred Stock, exclusively and
as a class, have the right to elect by majority vote one director to the Board
of Directors of the Company who is not a competitor of, supplier to or customer
of the Company or an affiliate of such a competitor, supplier or customer. To
date, the holders of the Series B Preferred Stock have not exercised this right.
In addition, pursuant to an Underwriting Agreement dated as of June 16, 1994
between the Company and Keane Securities Co., Inc. ("Keane"), the Company has
agreed that until June 8, 1999, at the request of Keane, the Company will use
its best efforts to cause one individual designated by Keane to be elected to
the Board of Directors of the Company. To date, Keane has not made such a
request.
 
    The Company's Certificate of Incorporation contains a provision, authorized
by Delaware law, which eliminates the personal liability of a director of the
Company to the Company or to any of its stockholders for monetary damages for a
breach of his fiduciary duty as a director, except in the case where the
director breached his duty of loyalty, failed to act in good faith, engaged in
intentional misconduct or knowingly violated a law, authorized a payment of a
dividend or approved a stock repurchase in violation of Delaware corporate law,
or obtained an improper personal benefit.
 
COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934
 
    Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
directors and executive officers, and persons who own more than ten percent of
the Novametrix Common Stock, to file with the Commission initial reports of
ownership and reports of changes in ownership of Novametrix Common Stock.
Officers, directors and greater than ten percent stockholders are required by
Commission regulations to furnish the Company with copies of all Section 16(a)
reports they file.
 
    To the Company's knowledge, based solely on a review of the copies of such
reports furnished to the Company and representations from certain persons that
no other reports were required, all Section 16(a) filing requirements applicable
to its officers, directors and greater than ten percent beneficial owners have
been complied with.

which may be brought before the Meeting. However, if any such other matters are
properly presented for action, it is the intention of the persons named in the
accompanying form of Proxy to vote the shares represented thereby in accordance
with their judgment on such matters.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Andros Incorporated
 
    In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of changes in shareholders' equity and of
cash flows present fairly, in all material respects, the financial position of
Andros Incorporated and its subsidiaries at July 30, 1995 and July 31, 1994, and
the results of their operations and their cash flows for each of the three years
in the period ended July 30, 1995, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1--OPERATIONS
 
    Andros Incorporated ("Andros") and its subsidiaries ("Company") designs,
manufactures, sells and services measurement analysis and diagnostic instruments
on a worldwide basis.
 
NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
FISCAL YEAR
 
    The Company operates on a 52-53 week fiscal year ending the last Sunday in
July. Fiscal 1995, 1994 and 1993 each comprised 52 weeks.
 
PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts and operating
results of Andros Incorporated and its wholly owned subsidiaries. All
significant intercompany accounts and transactions have been eliminated in
consolidation.
 
INDUSTRY SEGMENT
 
    The Company operates in a single industry segment--the design, manufacture
and service of measurement, analysis and diagnostic instruments. Its product
lines include analyzers for automotive and medical applications sold through
Original Equipment Manufacturers, and portable spectrum analysis instrumentation
sold to end users. The Company's products are sold primarily in domestic and
European markets.
 
CASH AND CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
    The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.
 
    Effective August 1, 1994, the Company adopted the provisions of Statement of
Financial Accounting Standards No. 115 ("FAS 115") "Accounting for Certain
Investments in Debt and Equity Securities". Adoption of FAS 115 had no material
effect on the Company's financial position or results of operations. In
accordance with the provisions of FAS 115, the Company classifies its
investments, and accounts for changes in fair value, as follows:
 
    -  Debt securities that the Company has the positive intent and ability to
       hold to maturity are classified as HELD-TO-MATURITY SECURITIES and
       reported at amortized cost.
 
    -  Debt and equity securities that are bought and held principally for the
       purpose of selling them in the near term are classified as TRADING
       SECURITIES and reported at fair value, with unrealized gains and losses
       included in earnings.
 
    -  Debt and equity securities not classified as either held-to-maturity
       securities or trading securities are classified as AVAILABLE-FOR-SALE
       SECURITIES and reported at fair value, with unrealized gains and losses
       excluded from earnings and reported in a separate component of
       shareholders' equity.
 
    Investments at July 30, 1995 and July 31, 1994 consist principally of United
States treasury notes and municipal obligations (principally various State of
California and various California county and agency obligations). These
investments are classified as available-for-sale securities and are stated at
cost which approximates fair value. Certain investments with maturities beyond
one year of the balance sheet date are classified as current assets since
management intends to redeem such investments prior to maturity.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
INVENTORIES
 
    Inventories are valued at the lower of cost (standard cost which
approximates first-in, first-out) or market.
 
PLANT AND EQUIPMENT
 
    Depreciation is computed using the straight-line method and the estimated
useful lives of the related assets which generally range from two to ten years.
The Company's building lease renewal options extend to August 2020, and
amortization of related leasehold improvements is based on the expectation that
renewal options will be exercised. The Company considers the estimated useful
life of the leasehold improvements when evaluating the period over which the
cost of leasehold improvements are amortized. Maintenance and repairs are
charged against income as incurred, and major improvements are capitalized.
Parts tooling costs, including software development costs, are capitalized,
included in machinery and equipment, and amortized generally on a
unit-of-production basis.
 
GOODWILL
 
    Goodwill is amortized using the straight-line method over the period of
expected benefit which is estimated to be fifteen years.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
    The Company evaluates its long-lived assets for potential impairment by
analyzing the operating results, trends and prospects of its products, including
gross cash flows therefrom, as well as comparing them to their competitors. The
Company also takes into consideration any other events or circumstances that
might indicate potential impairment. Based upon these evaluations, the Company
has determined that no impairment of recorded long-lived assets has occurred.
 
RESEARCH AND DEVELOPMENT
 
    Research and development expenses are charged against income as incurred.
 
REVENUE RECOGNITION
 
    Revenue from product sales is recognized at the time the product is shipped.
Revenue from extended warranty contracts is recognized over the terms of the
contracts using the straight-line method.
 
WARRANTY COSTS
 
    The Company provides for specific warranty items when they become known and
expenses routine warranty repairs as incurred.
 
INCOME TAXES
 
    In the first quarter of fiscal 1994, the Company adopted, effective as of
July 25, 1993, Statement of Financial Accounting Standards No. 109 ("FAS 109"),
"Accounting for Income Taxes". FAS 109 is an asset and liability approach that
requires the recognition of deferred tax assets and liabilities for the expected
tax consequences of events that have been recognized in the Company's financial
statements or tax returns. In estimating future tax consequences, FAS 109
generally considers all expected future events other than enactments of changes
in the tax laws or rates. Previously, the Company used the asset and liability

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
approach provided under Statement of Financial Accounting Standards No. 96 that
gave no recognition to future events other than the recovery of assets and
settlement of liabilities at their carrying amounts. Adoption of FAS 109 had no
effect on the Company's previously recorded deferred tax liability.
 
EARNINGS PER SHARE
 
    Earnings per share is computed using the weighted average number of shares
outstanding plus common stock equivalents such as stock options, warrants and
convertible debt. The number of shares used in the computation of earnings per
share for the three years was 4,820,900 in fiscal 1995, 4,797,900 in fiscal 1994
and 4,698,600 in fiscal 1993.
 
NOTE 3--ACQUISITION OF SCITEC CORPORATION
 
    In December 1993, the Company acquired Scitec Corporation for $7,000,000 in
cash and assumption of liabilities aggregating $1,171,300. Additionally, the
Scitec stockholders may become entitled to receive contingent payments of up to
$5,750,000 (less certain finders' fees) if and to the extent that revenues from
sales and products and services associated with the Scitec business during
calendar year 1995 reach specified targets.
 
    Scitec designs, manufactures and sells spectrum analysis instruments that
analyze selected elements contained in the materials tested. These products are
sold to end users principally for the detection of lead in paint. The
Consolidated Statement of Operations for fiscal 1994 includes the results of
operations of Scitec from the date of acquisition. The transaction was accounted
for as a purchase and the excess of the aggregate purchase price of $8,171,300
over the fair value of the assets acquired of Scitec of $1,629,500 was recorded
as goodwill ($6,541,800). If this acquisition had occurred as of the beginning
of the first quarter of fiscal 1993, the Company estimates that pro forma sales
would have been approximately $58,608,300 and $43,808,900 in fiscal 1994 and
fiscal 1993, respectively. Pro forma net income would have been approximately
$7,869,700, $1.64 per share, in fiscal 1994 and approximately $5,503,600, $1.17
per share, in fiscal 1993. (Such pro forma information is unaudited.)

    Software development costs are capitalized from the date technological
feasibility is established until the product is available for general release.
The capitalized costs are amortized beginning when the related products are
available for general release, and amortization is calculated on a
unit-of-production basis. The establishment of technological feasibility and the
ongoing assessment of recoverability of capitalized software costs requires
considerable judgment by management with respect to certain external factors
including, but not limited to, anticipated future gross revenue, estimated
economic life and changes in software and hardware technologies. At July 30,
1995 and July 31, 1994, capitalized software development costs totaled $258,400
and $535,200, net of related amortization of $2,219,500 and $1,942,700,
respectively.

    In August 1993, President Clinton signed into law the Omnibus Budget
Reconciliation Act of 1993 ("Act"). The Act included certain provisions which
affected Andros including, but not limited to, retroactive reinstatement of the
research and development tax credit, effective as of the beginning of fiscal
year 1993, and increasing the corporate tax rate from 34% to 35% for corporate
taxable income in excess of $10 million. The one-time adjustment to recorded
deferred income taxes for the increase in the corporate tax rate and the benefit
resulting from the retroactive reinstatement of the research and development tax
credit was a net benefit of approximately $65,000 which was recorded in the
first quarter of fiscal year 1994.

    At July 30, 1995, the Company had available approximately $1,093,000 and
$26,000 of net operating loss and tax credit carryforwards, respectively. These
carryforwards were acquired in connection with the fiscal 1994 acquisition of
Scitec (Note 3). Goodwill will be reduced in the future to the extent these
carryforwards are utilized to reduce Scitec's future taxable income. A valuation
allowance equal to the tax benefit applicable to these carryforwards has been
recorded at July 30, 1995 and July 31, 1994.
 
    The provision for income tax differs from the amounts that would be computed
by applying the federal statutory rate of 34% for the following reasons:

NOTE 7--SHAREHOLDERS' EQUITY (CONTINUED)
STOCK OPTIONS
 
    During fiscal 1992, the shareholders approved an amendment and restatement
of the Company's three existing stock plans: the 1980 Employee Stock Option Plan
("1980 Employee Plan"), the 1989 Employee Stock Option Plan ("1989 Employee
Plan"), and the Company's Stock Option Plan for Directors ("Directors Plan")
which consolidated the existing plans into a single stock plan, increased by
250,000 shares the number of shares for which options may be granted and amended
various other terms and provisions contained in such plans. Accordingly, all
outstanding options under the 1980 and 1989 Employee Plans and Directors Plan
have been incorporated into the Option Plan. However, each outstanding option
incorporated into the Option Plan will continue to be governed by the terms and
conditions of the instrument evidencing such grant, and nothing in the Option
Plan will affect the rights and obligations of the holders of such options with
respect to their acquisition of shares of Andros' common stock thereunder or
their exercise of any outstanding stock appreciation rights thereunder. In
December 1992, the shareholders approved an amendment to the Option Plan
increasing the number of shares reserved for issuance thereunder by 300,000
shares. In fiscal 1994, the shareholders approved an additional amendment to the
Option Plan further increasing the number of shares reserved for issuance
thereunder by an additional 300,000 shares. At July 30, 1995, 364,453 shares of
common stock were available for future grants under the Option Plan.
 
    Pursuant to the Company's Option Plan, the Compensation Committee of the
Board of Directors may grant options to key employees to purchase shares of
common stock either as an incentive stock option or as a non-qualified stock
option. The exercise price of incentive stock options granted may not be less
than 100% of the fair market value of the common stock on the date of grant, and
the exercise price of non-qualified options granted may not be less than 85% of
the fair value of the common stock on the date of grant. Options granted
terminate within ten years after the date of the grant and vest daily over three
to five-year periods. The Board of Directors may provide for acceleration of
vesting at its discretion. In the event of certain changes in control of the
Company, vesting of outstanding options will automatically accelerate. In the
event of certain other corporate transactions, unless assumed by a successor
corporation, vesting of outstanding options will automatically accelerate, and
the options will expire if not exercised prior to the consummation of such
corporate transaction. The Plan contains a stock appreciation right feature
whereby the Compensation Committee, at its discretion, may settle the whole or
any part of an exercisable installment of an option in exchange for the
surrender of such installment or partial installment. The settlement offer may
be made in shares of common stock, cash or both. The settlement offer shall be
equal to the excess of the fair market value of the shares over the option's
exercise price. The exercise price may be paid in the form of cash or the tender
of outstanding shares with a market value equal to the exercise price. In
addition, certain limited stock appreciation rights have been granted to
officers and directors of the Company in tandem with their outstanding options.
Any option with such a limited stock appreciation right in effect for at least
six months will automatically be canceled upon the occurrence of certain hostile
takeovers, and the optionee will in turn be entitled to a cash distribution from
the Company based upon the takeover price and the option price.
 
    New Board members will automatically be granted a non-qualified stock option
to purchase 25,000 shares of common stock. Each automatic grant will be equal to
100% of the fair market value per share of the common stock on the date of
grant. Options granted terminate within ten years of the date of grant: 15,000
shares vest after one year of Board service, and 5,000 shares vest upon the
completion of each of the next two years of Board service thereafter.

    The exercise of stock options resulted in an increase in common stock of
$353,412, $1,124,700 and $582,200 in fiscal 1995, 1994 and 1993, respectively.
 
NON-QUALIFIED STOCK OPTIONS
 
    Tax benefits realized by the Company from the exercise of non-qualified
stock options issued under stock option plans that result in ordinary income to
the optionee are added to shareholders' equity in the year benefits are
realized.
 
EMPLOYEE PARTICIPATION PLANS
 
    The Company has a stock purchase plan which permits employees to purchase
Andros' common stock at the lower of 85% of fair market value at the date of
purchase or 85% of the fair market value at the date of commencement of the
offering period. In addition, the Company has a Savings and Investment 401(k)
Plan ("Savings Plan") which, until amended in fiscal 1992, provided for matching
contributions by the Company, which may be settled through contributions of the
Company's common stock to the Savings Plan. The amended Savings Plan calls for
cash contributions only. Common stock increased $28,500, $32,000 and $36,300 in
fiscal 1995, 1994 and 1993, respectively, as a result of employee stock
purchases under these plans.
 
    At July 30, 1995, the Company has reserved 1,100,340 shares for issuance
under the above described stock option and stock purchase plan.
 
STOCK REPURCHASES
 
    In May 1994, the Board of Directors approved a stock repurchase program
authorizing the purchase of up to 500,000 shares of Andros' common stock on the
open market. To date, 56,000 shares have been repurchased for a cost of
$839,000. The Company intends to utilize these repurchased shares for issuances
of common shares applicable to options exercised under its stock option plans.
 
NOTE 8--SALES TO MAJOR CUSTOMERS AND EXPORT SALES
 
    During fiscal 1995, 42% of the Company's sales were made to three customers
that individually accounted for more than 10% of total sales. During fiscal
1994, 25% of the Company's sales were made to two customers that individually
accounted for more than 10% of total sales. During fiscal 1993, 55% of the
Company's sales were made to four customers that individually accounted for more
than 10% of total sales. The Company's export sales for fiscal 1995, 1994 and
1993 amounted to $23,796,000, $36,356,400 and

$27,890,300, respectively. The Company maintains a sales office in Zurich,
Switzerland and a service depot in Belp, Switzerland. Export sales are
transacted in United States dollars.
 
NOTE 9--COMMITMENTS
 
    The Company occupies office and plant facilities worldwide under various
lease agreements. The Berkeley facility is leased under an agreement expiring in
August 2005 at an annual rental of $242,800. This lease agreement contains
renewal options for an additional 15 years. Total rent expense for fiscal years
1995, 1994 and 1993 was $406,200, $398,900 and $346,800, respectively.
 
NOTE 10--CONCENTRATION OF CREDIT RISK
 
    The Company invests its excess cash primarily in short-term U.S. Treasury
securities and corporate obligations. The investments generally mature within
one year and are therefore subject to little market risk. The Company has not
incurred losses related to these investments.
 
    Concentrations of credit risk with respect to trade receivables are
mitigated due to the small number of large creditworthy customers comprising the
Company's customer base. Ongoing credit evaluations of customers' financial
condition are performed. The company maintains reserves for potential credit
losses, and such losses, in the aggregate, have not exceeded management's
expectations.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To The Board of Directors and Shareholders,
 
Andros Holdings Inc.:
 
We have audited the accompanying consolidated balance sheet of Andros Holdings
Inc. as of July 31, 1996, and the related consolidated statements of operations,
shareholders' deficit and cash flows for the period from December 5, 1995 (date
of incorporation) to July 31, 1996, and the consolidated statements of
operations, shareholders' equity and cash flows of Andros Incorporated for the
period from July 31, 1995 to March 26, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Andros Holdings Inc.
at July 31, 1996, and the results of its operations and its cash flows for the
period from December 5, 1995 (date of incorporation) to July 31, 1996, and the
consolidated statements of operations, shareholders' equity and cash flows of
Andros Incorporated for the period from July 31, 1995 to March 26, 1996, in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION:
 
Andros Holdings Inc. and its wholly owned subsidiaries, Andros Incorporated,
Scitec Inc. and Andros Foreign Sales Corporation (Andros Holdings or
collectively the Company) design, manufacture, sell and service measurement,
analytic and diagnostic devices for medical, automotive and environmental
applications. Andros Holdings, incorporated in the state of Delaware on December
5, 1995, had no material operations prior to March 26, 1996. The fiscal year end
of Andros Holdings is December 31.
 
Genstar Capital Partners II, L.P. (Genstar) formed Andros Holdings for the
purpose of acquiring Andros Incorporated (a U.S. publicly traded corporation).
On March 26, 1996 Andros Holdings, through Andros Acquisition Inc. (Andros
Acquisition), a wholly owned subsidiary, purchased, through a public tender
offer, the outstanding stock of Andros Incorporated (Andros) for $18.00 per
share. As of May 14, 1996, Andros Holdings acquired the remaining Andros shares
it did not own. Upon the completion of the acquisition of Andros, Andros
Acquisition was merged into Andros and was liquidated. Minority interest related
to the loss between March 27, 1996 and May 14, 1996 was not material. The total
acquisition price was approximately $88.1 million which was paid in cash. In
connection with the transaction, the Company issued common stock for $17
million, and Andros Acquisition entered into a $15 million subordinated loan
agreement, a $27 million term credit facility and a $15 million revolving credit
facility of which $5.4 million was used.
 
The acquisition of Andros was accounted for as a purchase as of March 27, 1996.
The total purchase price of $88.1 million (including the costs of acquisition of
$2.9 million), has been allocated to the net assets acquired based on their
estimated fair values as of March 26, 1996. The Company allocated a portion of
the purchase price to various in-process research and development projects that
had identifiable economic value and expensed this value as of the date of the
acquisition. The purchased technology is related to the Company's products which
are technically feasible and which have proven commercial feasibility, and
accordingly, the fair value of the purchased technology is amortized on a
straight-line basis over the period of expected benefit which is estimated to be
25 years.
 
The fair value of the assets acquired (net of cash acquired of $30,318,700) and
liabilities assumed were as follows:

Holdings. The merger agreement contains certain terms and conditions including:
an earn-out shares provision, accuracy of representations and warranties,
approval of the transaction by Novametrix shareholders and execution of a voting
agreement. The merger agreement also provides for a termination fee of $3

terminating party to the other party.
 
3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
PRINCIPLES OF CONSOLIDATION:
 
The consolidated financial statements include consolidated operating results of
Andros (Andros operated on a 52-53 week fiscal year ending the last Sunday in
July), for the period from July 31, 1995 to March 26, 1996 and the consolidated
financial statements for Andros Holdings and its wholly owned subsidiaries for
the period from incorporation to July 31, 1996 (Andros Holdings had no material
operating activity from December 5, 1995 (date of incorporation) to March 26,
1996). All significant intercompany accounts and transactions have been
eliminated in consolidation.
 
BUSINESS AND CREDIT CONCENTRATIONS:
 
Andros operates in a single industry segment--the design, manufacture and
service of measurement, analytic and diagnostic instruments. Its product lines
include analyzers for automotive and medical applications sold through original
equipment manufacturers, and portable spectrum analysis instrumentation sold to
end users. Andros' products are sold in domestic and international markets.
 
CASH AND CASH EQUIVALENTS:
 
The Company considers all highly liquid investments with original maturities of
three months or less to be cash equivalents.
 
INVENTORIES:
 
Inventories are valued at the lower of cost (standard cost which approximates
first-in, first out) or market. The Company's inventories include high
technology components that may be specialized in nature and subject to
technological obsolescence. While the company attempts to minimize the required
inventory on hand and considers technological obsolescence when estimating
required reserves to reduce recorded amount to market value, it is reasonably
possible that such estimates could change in the near future.
 
The Consolidated Statement of Operations of Andros Incorporated for the period
from July 31, 1995 to March 26, 1996 includes a provision for excess and
obsolete inventories in the amount of $3,866,000 based on the Company's
estimates of future realizability.
 
PLANT AND EQUIPMENT:
 
Depreciation is computed using the straight-line method and the estimated useful
lives of the related assets which generally range from two to ten years. The
Company's building lease renewal options extend to August 2020, and amortization
of related leasehold improvements is based on the expectation that renewal
options will be exercised. The Company considers the estimated useful life of
the leasehold improvements
 
                                                                     (CONTINUED)
                                      F-21

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
when evaluating the period over which the cost of leasehold improvements are
amortized. Maintenance and repairs are charged against income as incurred and
major improvements are capitalized. Tooling costs, including software
development costs, are capitalized when appropriate, and are included in
machinery and equipment, and amortized generally on a unit-of-production basis.
 
IMPAIRMENT OF LONG-LIVED ASSETS:
 
During March 1995, the Financial Accounting Standards Board issued Statement No.
121 (SFAS No. 121), "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of," which requires the Company to review for
impairment of long-lived assets, certain identifiable intangibles, and goodwill
related to those assets whenever events or changes in circumstance indicate that
the carrying amount of an asset might not be recoverable. In certain situations,
an impairment loss would be recognized.
 
Andros evaluates its long-lived assets for potential impairment by analyzing the
operating results, trends and prospects of its products, including gross cash
flows therefrom, as well as comparing them to their competitors. The Company
also takes into consideration any other events or circumstances that might
indicate potential impairment. Based upon these evaluations, the Company has
determined that no impairment of recorded long-lived assets has occurred.
 
RESEARCH AND DEVELOPMENT:
 
Research and development costs are charged to expense as incurred.
 
REVENUE RECOGNITION AND ALLOWANCE FOR DOUBTFUL ACCOUNTS:
 
Revenue from product sales is recognized at the time the product is shipped and
after all significant conditions of sale have been met. The Company reviews a
customer's credit history before extending credit. The Company establishes an
allowance for doubtful accounts based upon factors surrounding the credit risk
of specific customers, historical trends and other information.
 
FOREIGN CURRENCY ACCOUNTING:
 
Substantially all of Andros' sales are denominated in U.S. dollars. Foreign
currency transactions during the period are immaterial and are included in
operations.
 
WARRANTY COSTS:
 
The Company's products generally have a warranty period of three months to 18
months from customer receipt. Estimated future costs of repair, replacement and
customer accommodations are reflected in the accompanying consolidated financial
statements.
 
INCOME TAXES:
 
Income taxes are accounted for using the liability method. Deferred tax assets
and liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax basis. Deferred tax assets and
liabilities
 
                                                                     (CONTINUED)

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
are measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
The carrying amounts of cash and cash equivalents, and accrued liabilities are a
reasonable estimate of their fair value due to their short term nature. The
estimated values of Andros Holdings' long term debt are based on interest rates
at July 31, 1996 for issues with similar remaining maturities.
 
The estimated fair value amounts of Andros Holdings' financial instruments have
been determined by Andros Holdings, using appropriate market information and
valuation methodologies. Considerable judgment is required to develop the
estimates of fair value; thus, the estimates provided herein are not necessarily
indicative of the amounts that could be realized in a current market exchange.
 
Andros Holdings calculates the fair value of financial instruments and includes
this additional information in the notes to the consolidated financial
statements when the fair value is different than the book value of those
financial instruments. When the fair value is equal to the book value, no
additional disclosure is made. Andros Holdings uses quoted market prices
whenever available to calculate these fair values. When quoted market prices are
not available, Andros Holdings uses standard pricing models for various types of
financial instruments which take into account the present value of estimated
future cash flows. The effect of using different market assumptions and/or
estimation methodologies may be material to the estimated fair value amounts.
 
USE OF ESTIMATES:
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reported period. Actual results could differ from those estimates.
 
RECENT PRONOUNCEMENTS:
 
During October 1995, the Financial Accounting Standards Board issued Statement
No. 123 (SFAS No. 123), "Accounting for Stock-Based Compensation," which
established a fair value based method of accounting for stock-based compensation
plans and requires additional disclosures for those companies who elect not to
adopt the new method of accounting. While the Company studies the impact of this
pronouncement, it continues to account for stock options under APB Opinion No.
25, "Accounting for Stock Issued to Employees." SFAS No. 123 will be effective
for fiscal years beginning after December 15, 1995 and will require the Company
to provide additional disclosures in the financial statements for the year
ending December 31, 1996.
 
                                                                     (CONTINUED)

TENDER FACILITY:
 
The Company used a tender facility of $24.8 million, bearing interest at 10% per
annum, to finance the purchase of 58% of Andros. The tender facility was repaid
with interest on May 15, 1996 through the use of a term loan facility (see
following). The loan was collateralized by substantially all assets of the
Company including the shares of its subsidiaries.
 
TERM LOAN:
 
On March 25, 1996, the Company entered into a $27 million term loan facility
with certain banks. The term loan bears interest at a variable rate determined
by reference to the base rate (which is defined as 1.75% plus the higher of (i)
the Prime Rate or (ii) the rate which is 0.5% in excess of the Federal Funds

Rate) or Adjusted Eurodollar Rate (8.5% and 10% as of July 31, 1996). Repayment
of the principal is due quarterly commencing June 30, 1996, and ending March 31,
2001, at $625,000 per quarter and increasing by $375,000 up to a maximum payment
of $2,000,000 per payment after each fourth payment, until maturity. The term
loan may be repaid without penalty. The full amount of the facility was drawn on
May 15, 1996. The loan is collateralized by substantially all assets of the
Company including the shares of its subsidiaries. Certain financing costs
amounting to $2,142,800 have been capitalized and are being amortized over the
term of the loan using the effective interest method. The terms of the term loan
facility require the Company to maintain certain financial ratios, to place
certain limitations on declaration and payment of dividends and similar
distributions and to comply with other financial covenants.
 
SUBORDINATED LOAN:
 
On March 25, 1996, the Company entered into a $15 million subordinated loan
agreement with certain lenders. The loan requires quarterly interest payments in
arrears, commencing May 15, 1996, at an annual interest rate of 13%. Principal
repayments of $1,875,000 are due quarterly, commencing with the earlier of (i)
the quarter ending on June 30, 2001, or (ii) the quarter immediately following
repayment in full of the term loan facility. Certain financing costs amounting
to $1,649,200 have been capitalized and amortized over the term of the loan. The
terms of the subordinated loan agreement require the Company to maintain certain
financial ratios and to comply with other financial covenants.
 
WARRANTS:
 
In connection with the term loan and subordinated loan agreement, the Company
issued warrants to the lenders of the term loan and the subordinated loan to
acquire up to a total of 8,000 Class A Common Shares, at an exercise price of
$0.01 per share at any time prior to March 25, 2006. The difference between the
exercise price of the warrants and the fair value of the Class A Common Shares
at the time of the issue of the warrants was approximately $1,390,800, which was
accounted for as additional paid-in capital and a discount to the related debt.
The discount is amortized over the term of the related debt using the effective
interest method.
 
MATURITY:
 
The aggregate maturities of the term loan and subordinated loan at July 31,
1996, are as follows:

5. DEBT: (CONTINUED)
REVOLVING LOAN:
 
On March 25, 1996 the Company entered into a $15 million Revolving Loan
facility. Loans under this facility bear interest at a variable rate determined
by reference to the base rate (which is defined as 1.75% plus the higher of (i)
the Prime Rate or (ii) the rate which is 0.5% in excess of the Federal Funds
Effective Rate) or the Adjusted Eurodollar Rate (10% as of July 31, 1996). The
loan, which expires on March 31, 2001, is collateralized by substantially all
assets of the Company including the shares of its subsidiaries. As of July 31,
1996, the Company has drawn $4.2 million on this facility. The revolving loan
agreement requires the Company to maintain certain financial ratios and to
comply with other financial covenants.
 
6. COMMITMENTS:
 
The Company occupies office and plant facilities under various operating lease
agreements. The main office and manufacturing site in Berkeley, California is
leased under an agreement expiring in August 2005 at an annual rental of
approximately $257,000 as of July 31, 1996, subject to increases based on
appraised market value (currently under negotiation) and periodic adjustment for
changes based on the Consumer Price Index. This lease agreement contains renewal
options for an additional 15 years. Total rent expense for the period from July
31, 1995 to March 26, 1996 and the period from March 27, 1996 to July 31, 1996
was $259,900 and $121,100, respectively.
 
7. BENEFIT PLAN:
 
The Andros' Saving and Investment Plan (the Plan) was established pursuant to
section 401(k) of the Internal Revenue Code of 1986, as amended. Essentially all
employees are eligible to participate and may elect to contribute to the Plan up
to 15% of their compensation, subject to certain limitations. The Company
matches 50% of an individual participant's contribution in cash each quarter, up
to 6% of the participant's salary. The matching contributions approximated
$93,447 and $158,500 for the period from March 27, 1996 to July 31, 1996 and for
the period from July 31, 1995 to March 26, 1996, respectively.
 
8. CONCENTRATION OF CREDIT RISK:
 
Cash and cash equivalents are primarily invested in deposits with one major bank
in the United States. Deposits in this bank may exceed the amount of insurance
provided on such deposits. Andros has not experienced any losses on deposits of
cash and cash equivalents.
 
Concentrations of credit risk with respect to trade receivables are mitigated
due to the small number of large creditworthy customers comprising the Company's
customer base. Ongoing credit evaluations of customers' financial condition are
performed. The Company maintains reserves for potential credit losses and such
losses, in the aggregate, have not exceeded management's expectations.
 
9. SHAREHOLDER'S EQUITY:
 
COMMON STOCK:
 
The authorized shares of the Company consist of 300,000 shares of which 150,000
shares are voting Class A common shares, par value $.01 per share, and 150,000
shares are nonvoting Class B common shares, par

value $.01 per share. As of July 31, 1996, 89,800 Class A common shares and no
Class B common shares were issued and outstanding.
 
EQUITY UNIT AWARD AGREEMENT:
 
During March 1996 the Company issued 2,190 Equity Unit Awards (EUA) to four
members of the management of Andros for $189.34 per unit. Subsequently, the
Company repurchased 1,736 EUAs from a member of management at the issuance
price. The holders of the EUAs are entitled to receive, at the option of the
Company, Class A common shares or the fair market equivalent upon the earliest
of the following events (i) the termination of the participant's employment with
the Company for any reason, (ii) a public offering, (iii) the sale of the
Company or (iv) the tenth anniversary of the agreement. However, the term may be
extended by the stockholders for an additional period not to exceed ten years
from the original expiration date.
 
10. STOCK OPTION PLAN:
 
All options granted as of March 26, 1996 of Andros, whether or not then
exercisable, were repurchased by Andros. The net expense of the repurchase of
approximately $4.1 million representing the excess of $18.00 per share over the
grant price has been recorded by Andros as compensation expense in the period of
July 31, 1995 to March 26, 1996.
 
In July 1996, the Company authorized the 1996 Equity Incentive Plan (the Plan)
under which the Board of Directors may issue incentive and nonqualified stock
options to employees, officers, and consultants of the Company. The Board of
Directors has the authority to determine to whom options will be granted at
prices not lower than fair market value at the date of grant, and nonstatutory
options may be granted at prices not lower than 85% of fair market value at the
date of grant as determined by the Board of Directors at date of grant. Options
granted under the Plan generally become exercisable ratably over 60 months. The
right of exercise generally expires ten years from the date of the grants. In
connection with the authorization of the Plan, Andros Holdings reserved 10,918
shares of common stock for issuance under the Plan. As of July 31, 1996 no
options had been granted. In September 1996 approximately 2,900 options were
granted with an exercise price of $189.34 per share.

Although realization of the deferred tax assets is not assured, the Company
believes that it is more likely than not that all of the deferred tax assets
will be realized. The amount of the deferred tax assets considered realizable
could be reduced if estimates of future taxable income decline significantly.
 
At July 31, 1996, Andros Holdings has available approximately $1,093,000 and
$26,000 of net operating loss and tax credit carryforwards, respectively. These
carryforwards were acquired in connection with the fiscal 1994 acquisition of
Scitec. A valuation allowance equal to the tax benefit applicable to these
carryforwards has been recorded at July 31, 1996.

                          AGREEMENT AND PLAN OF MERGER
 
    AGREEMENT AND PLAN OF MERGER dated as of July 29, 1996, among Andros
Holdings Inc., a Delaware corporation (the "Company"), Novametrix Medical
Systems Inc., a Delaware corporation ("Novametrix"), and Novametrix Acquisition
Corp., a Delaware corporation and a wholly owned subsidiary of Novametrix (the
"Merger Subsidiary").
 
    WHEREAS, the Boards of Directors of Novametrix, the Merger Subsidiary and
the Company have approved this Agreement and the Merger (as defined below); and
 
    WHEREAS, for Federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of the
Code (as defined below).
 
    NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, the
parties hereto agree as follows:
 
                                   ARTICLE I.
                                   THE MERGER
 
    SECTION 1.01  THE MERGER.  (a) At the Effective Time (as defined in Section
1.01(b)), the Merger Subsidiary shall be merged (the "Merger") with and into the
Company in accordance with the General Corporation Law of the State of Delaware
("Delaware Law"), whereupon the separate existence of the Merger Subsidiary
shall cease, and the Company shall be the surviving corporation (the "Surviving
Corporation").
 
    (b) As soon as practicable after satisfaction or, to the extent permitted
hereunder, waiver of all conditions to the Merger, the Company and the Merger
Subsidiary will file a certificate of merger with the Secretary of State of the
State of Delaware and make all other filings or recordings required by Delaware
Law in connection with the Merger. The closing of the Merger will take place at
the offices of Haythe & Curley, 237 Park Avenue, New York, New York 10017, or
such other place as the parties may agree. The Merger shall become effective at
such time as the certificate of merger is duly filed with the Secretary of State
of the State of Delaware or at such later time as is specified in the
certificate of merger (the "Effective Time").
 
    (c) From and after the Effective Time, the Surviving Corporation shall
possess all the assets, rights, privileges, powers and franchises and be subject
to all of the liabilities, restrictions, disabilities and duties of the Company
and the Merger Subsidiary, all as provided under Delaware Law.
 
    SECTION 1.02  CONVERSION OF SHARES.  At the Effective Time:
 
        (a) each outstanding share of common stock, par value $.01 per share
    (the "Shares"), of the Company held by the Company as treasury stock or
    owned by Novametrix or any subsidiary of Novametrix immediately prior to the
    Effective Time shall be cancelled, and no payment (whether in cash, shares
    of Novametrix' common stock, par value $.01 per share (the "Novametrix
    Common Stock"), or other consideration) shall be made with respect thereto;
 
        (b) each share of common stock, par value $.01 per share, of the Merger
    Subsidiary outstanding immediately prior to the Effective Time shall be
    converted into and become one share of common stock, par value $.01 per
    share, of the Surviving Corporation with the same rights, powers and
    privileges as the shares so converted and shall constitute the only
    outstanding shares of capital stock of the Surviving Corporation; and
 
        (c) except as otherwise provided in Section 1.02(a), each Share
    outstanding immediately prior to the Effective Time shall be converted into
    the right to receive (i) that number (the "Exchange Number") of fully paid
    and nonassessable shares of Novametrix Common Stock equal to (x) .8181818
    multiplied by the number of shares of Novametrix Common Stock outstanding
    immediately prior to the Effective Time (assuming conversion of all then
    outstanding shares of preferred stock, $1.00 par
 
                                      A-1
<PAGE>
    value (the "Novametrix Preferred Stock"), of Novametrix) divided by (y) the
    number of Shares outstanding immediately prior to the Effective Time
    (assuming the exercise in full of all then outstanding Company Options and
    Company Warrants (each as hereinafter defined)), computed to four decimal
    places and (ii) one Right (as defined in Section 1.06 hereof) (such Right
    together with the Exchange Number of shares of Novametrix Common Stock are
    hereinafter referred to as the "Merger Consideration").
 
    SECTION 1.03  SURRENDER AND PAYMENT.  (a) Each holder of Shares that have
been converted into a right to receive Novametrix Common Stock, upon surrender
to Novametrix of a certificate or certificates representing such Shares, will be
entitled to receive in exchange therefor (i) that number of whole shares of
Novametrix Common Stock which such holder has the right to receive pursuant to
Section 1.02, (ii) that number of Rights which such holder has the right to
receive pursuant to Section 1.02 and (iii) cash in lieu of fractional shares of
Novametrix Common Stock which such holder has the right to receive pursuant to
Section 1.05, and the certificate or certificates for the Shares so surrendered
shall be cancelled. Until so surrendered, each such certificate shall, after the
Effective Time, represent for all purposes, only the right to receive upon such
surrender the Merger Consideration and cash in lieu of any fractional shares of
Novametrix Common Stock as contemplated by this Section 1.03 and Section 1.05.
 
    (b) If any shares of Novametrix Common Stock are to be issued to a Person
other than the registered holder of the Shares represented by the certificate or
certificates surrendered in exchange therefor, it shall be a condition to such
issuance that the certificate or certificates so surrendered shall be properly
endorsed or otherwise be in proper form for transfer and that the Person
requesting such issuance shall pay to Novametrix any transfer or other taxes
required as a result of such issuance to a Person other than the registered
holder of such Shares or establish to the satisfaction of Novametrix that such
tax has been paid or is not payable. For purposes of this Agreement, "Person"
means an individual, a corporation, a partnership, an association, a trust or
any other entity or organization, including a government or political
subdivision or any agency or instrumentality thereof.
 
    (c) After the Effective Time, there shall be no further registration of
transfers of Shares. If, after the Effective Time, certificates representing
Shares are presented to the Surviving Corporation, they shall be cancelled and
exchanged as provided for, and in accordance with the procedures set forth, in
this Article I.
 
    (d) Notwithstanding the foregoing, Novametrix shall not be liable to any
holder of Shares for any amount paid, or any shares of Novametrix Common Stock
or Rights delivered, to a public official pursuant to applicable abandoned
property laws. Any shares of Novametrix Common Stock or any Rights or other
amounts remaining unclaimed by holders of Shares six months after the Effective
Time (or such earlier date immediately prior to such time as such amounts would
otherwise escheat to or become property of any governmental entity) shall, to
the extent permitted by applicable law, become the property of Novametrix free
and clear of any claims or interest of any Person previously entitled thereto.
 
    (e) The Surviving Corporation shall be entitled to deduct and withhold from
the cash, if any, payable in lieu of fractional shares otherwise payable
pursuant to this Agreement to any holder of Shares such amounts as the Surviving
Corporation is required to deduct and withhold with respect to the making of
such payment under the Code, or any provisions of state, local or foreign tax
law. To the extent that amounts are so withheld, such withheld amounts shall be
treated for all purposes of this Agreement as having been paid to the holder of
such Shares in respect of which such deduction and withholding was made by the
Surviving Corporation.
 
    (f) No dividends or other distributions on shares of Novametrix Common Stock
shall be paid to the holder of any unsurrendered certificates representing
Shares until such certificates are surrendered as provided in this Section. Upon
such surrender, there shall be paid, without interest, to the person in whose
name the certificates representing the shares of Novametrix Common Stock into
which such Shares were converted are registered, all dividends and other
distributions paid in respect of such Novametrix Common Stock on a date
subsequent to, and in respect of a record date after, the Effective Time.
 
                                      A-2
<PAGE>
    SECTION 1.04  STOCK OPTIONS, EQUITY UNITS AND WARRANTS.  (a) At the
Effective Time, each outstanding option to purchase Shares (a "Company Option")
issued pursuant to the Stock Option Plan of the Company (the "Company Stock
Option Plan"), whether vested or unvested, shall be assumed by Novametrix. Each
Company Option shall be deemed to constitute an option to acquire, on the same
terms and conditions as were applicable under such Company Option, (i) (x) the
same number of whole shares of Novametrix Common Stock as the holder of such
Company Option would have been entitled to receive pursuant to the Merger had
such holder exercised such option in full immediately prior to the Effective
Time and (y) a number of Rights equal to the number of Rights which the holder
of such Company Option would have been entitled to receive pursuant to the
Merger had such holder exercised such option in full immediately prior to the
Effective Time, (ii) at a price per share (rounded up to the nearest whole cent)
equal to (A) the aggregate exercise price for the Shares otherwise purchasable
pursuant to such Company Option divided by (B) the number of whole shares of
Novametrix Common Stock deemed purchasable pursuant to such Company Option;
provided, however, that in the case of any Company Option to which Section 421
of the Code applies by reason of its qualification under Section 422 of the Code
("qualified stock options"), the option price, the number of shares purchasable
pursuant to such Company Option and the terms and conditions of exercise of such
Company Option shall be determined in order to comply with Section 424(a) of the
Code. No additional consideration shall be required to be paid with respect to
the Rights. Any partial exercise of a Company Option shall result in a
proportional issuance of the Rights subject to such Company Option. As soon as
practicable after the Effective Time, Novametrix shall deliver to the holders of
Company Options appropriate notices setting forth such holders' rights with
respect to such Company Options pursuant to the Company Stock Option Plan and
the certificates evidencing the grants of such Company Options shall continue in
effect on the same terms and conditions (subject to the adjustments required by
this Section 1.04(a) after giving effect to the Merger and the assumption by
Novametrix as set forth above). Novametrix shall comply with the terms of the
Company Stock Option Plan and shall use reasonable efforts to ensure, to the
extent required by, and subject to the provisions of, such Plan, that Company
Options which qualified as qualified stock options prior to the Effective Time
continue to qualify as qualified stock options of Novametrix after the Effective
Time. Novametrix shall take all corporate action necessary to reserve for
issuance a sufficient number of shares of Novametrix Common Stock for delivery
upon exercise of Company Options assumed by it in accordance with this Section
1.04(a).
 
    (b) At the Effective Time, the Company will pay to each holder of Equity
Units (as defined in the Equity Unit Award Agreements, dated as of March 25,
1996 between the Company and each of the holders thereof (the "EUA
Agreements")), pursuant to such holders' EUA Agreement, shares of Company Common
Stock.
 
    (c) At the Effective Time, each outstanding warrant to purchase Shares (a
"Company Warrant") shall be assumed by Novametrix. Each Company Warrant shall be
deemed to constitute a warrant to acquire, on the same terms and conditions as
were applicable under such Company Warrant, (i) the same number of whole shares
of Novametrix Common Stock as the holder of such Company Warrant would have been
entitled to receive pursuant to the Merger had such holder exercised such
warrant in full immediately prior to the Effective Time and (y) a number of
Rights equal to the number of Rights which the holder of such Company Warrant
would have been entitled to receive pursuant to the Merger had such holder
exercised such warrant in full immediately prior to the Effective Time, (ii) at
a price per share (rounded up to the nearest whole cent) equal to (A) the
aggregate exercise price for the Shares otherwise purchasable pursuant to such
Company Warrant divided by (B) the number of whole shares of Novametrix Common
Stock deemed purchasable pursuant to such Company Warrant. No additional
consideration shall be required to be paid with respect to the Rights. Any
partial exercise of Company Warrant shall result in a proportional issuance of
the Rights subject to such Company Warrant. Novametrix shall take all corporate
action necessary to reserve for issuance a sufficient number of shares of
Novametrix Common Stock for delivery upon exercise of Company Warrants assumed
by it in accordance with this Section 1.04(c).
 
                                      A-3
<PAGE>
    (d) Prior to the Effective Time, (i) the Company shall use its best efforts
to obtain any consents required from holders of Company Options granted under
the Company Stock Option Plan or holders of the Equity Units, as the case may
be, and (ii) the Company shall make any amendments to the terms of such stock
option award or plan or compensation plans or arrangements or other applicable
agreements that, in the case of either clauses (i) or (ii), are necessary to
give effect to the transactions contemplated by Section 1.04(a) and (b).
 
    SECTION 1.05  FRACTIONAL SHARES.  No fractional shares of Novametrix Common
Stock shall be issued in the Merger. All fractional shares of Novametrix Common
Stock that a holder of Shares would otherwise be entitled to receive as a result
of the Merger shall be aggregated and if a fractional share results from such
aggregation, such holder shall be entitled to receive, in lieu thereof, an
amount in cash determined by multiplying the average of the daily closing sale
price per share of Novametrix Common Stock on the Nasdaq National Market for the
ten trading days immediately preceding the Effective Time by the fraction of a
share of Novametrix Common Stock to which such holder would otherwise have been
entitled. No such cash in lieu of fractional shares of Novametrix Common Stock
shall be paid to any holder of Shares until certificates representing such
Shares are surrendered and exchanged in accordance with Section 1.03.
 
    SECTION 1.06  LIMITED ANTIDILUTION RIGHTS.
 
    (a) Novametrix has authorized the issuance of contingent rights to receive
shares of Novametrix Common Stock (the "Rights") and, at the Effective Time,
will issue such Rights to holders of record of Shares as of the Effective Time
in accordance with Section 1.02(c) and to holders of Company Options and Company
Warrants who exercise such options or warrants after the Effective Time in
accordance with Section 1.04(a) or Section 1.04(c). The Rights shall not be
transferable, except that Genstar Capital Partners II, L.P., a Delaware limited
partnership ("Genstar"), may transfer Rights to its general and limited partners
upon receipt by Novametrix of (i) an opinion of counsel to Genstar reasonably
satisfactory to Novametrix to the effect that such transfer will not violate the
Securities Act or any state or foreign securities laws and (ii) a representation
letter from each such transferee in form and substance reasonably satisfactory
to Novametrix. The Rights shall not be evidenced by certificates. Novametrix
shall not issue fractional Rights.
 
    (b) Novametrix has authorized the issuance of and will hold in reserve the
shares of Novametrix Common Stock issuable pursuant to the Rights (the
"Underlying Shares"), and monthly, on the first business day after the end of
each month in which an Antidilution Event (as hereinafter defined) shall have
occurred after the month in which the Effective Date shall have occurred (each
such date, an "Antidilution Date") (until and including the first business day
of the month immediately succeeding the later of the month in which the last of
the remaining warrants and options to acquire shares of Novametrix Common Stock
outstanding immediately prior to the Effective Time and Company Options and
Company Warrants shall have expired or been exercised), Novametrix will issue
Underlying Shares to Rights holders as set forth in Section 1.06(c) with respect
to any Antidilution Events (as hereinafter defined) which shall have occurred
during the immediately preceding month.
 
    (c) Each Right grants to the holder thereof the right to receive from
Novametrix on each Antidilution Date a number of Underlying Shares equal to (x)
the sum of (i) .8181818 multiplied by the number of shares of Novametrix Common
Stock issued by Novametrix pursuant to warrants or options to acquire shares of
Novametrix Common Stock outstanding immediately prior to the Effective Time (but
excluding any such shares issued upon conversion of the Novametrix Preferred
Stock) and (ii) the number of shares of Novametrix Common Stock which were
issuable by Novametrix upon the exercise of Company Options or Company Warrants
(including Underlying Shares so issuable as provided in Section 1.06(e)), which
Company Options or Company Warrants were cancelled or otherwise expired
unexercised, in either case during the preceding month (or, in the case of the
first Antidilution Date after the issuance of such Right, after the Effective
Time) divided by (y) the number of Rights then outstanding or issuable upon the
exercise of all then outstanding Company Options and Company Warrants, computed
to four decimal places. The issuance by Novametrix of Novametrix Common Stock
pursuant to warrants or options and the
 
                                      A-4
<PAGE>
cancellation or expiration of Company Options or Company Warrants as aforesaid
are herein referred to as "Antidilution Events". Antidilution Events shall not
include, and Rights shall not grant the holders thereof the right to receive
shares of Novametrix Common Stock in respect of, issuances at or after the
Effective Time of any Novametrix Securities (as defined in Section 4.05) except
for shares of Novametrix Common Stock issued pursuant to options and warrants
outstanding immediately prior to the Effective Time.
 
    (d) Novametrix shall deliver, or arrange to have delivered, on each
Antidilution Date certificate(s) representing the number of shares of Novametrix
Common Stock issuable pursuant to each Right on such Antidilution Date
registered in the name of the person to whom such Right was issued at the
address of such person as it appears on the records of Novametrix. Novametrix
shall not issue fractional shares of Novametrix Common Stock to Rights holders.
The number of shares of Novametrix Common Stock that each Rights holder shall be
entitled to receive on each Antidilution Date shall be rounded down to the
nearest whole share.
 
    (e) Notwithstanding anything to the contrary contained herein, upon the
occurrence of an Antidilution Event, the number of shares of Novametrix Common
Stock issuable upon the exercise of each then outstanding Company Option and
Company Warrant shall be increased by the number of Underlying Shares which
would have been issuable pursuant to the Rights subject to such Company Option
or Company Warrant (assuming such Rights were then outstanding).

                                  ARTICLE III.
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
    The Company represents and warrants to Novametrix that:
 
    SECTION 3.01  CORPORATE EXISTENCE AND POWER.  The Company is a corporation
duly incorporated, validly existing and in good standing under the laws of the
State of Delaware, and has all corporate powers and all governmental licenses,
permits, authorizations, consents and approvals required to carry on its
business as now conducted except where the failure to do so would not have or
reasonably be expected to have, individually or in the aggregate, a material
adverse effect on the financial condition, business, assets or results of
operations of the Company and its Subsidiaries (as defined in Section 3.06(a)
hereof) taken as a whole (a "Company Material Adverse Effect"). The Company is
duly qualified to do business as a foreign corporation and is in good standing
in each jurisdiction where the character of the property owned or leased by it
or the nature of its activities makes such qualification necessary, except for
those jurisdictions where the failure to be so qualified would not have or
reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect. The Company has heretofore delivered to Novametrix true
and complete copies of the Company's certificate of incorporation and bylaws as
currently in effect. The Company does not own and has never owned any assets or
properties other than the capital stock of Andros and Andros's predecessor and
is not engaged and has never engaged in any activities other than in connection
with Andros and Andros's Subsidiaries and in connection with or as contemplated
by this Agreement.
 
    SECTION 3.02  CORPORATE AUTHORIZATION.  The execution, delivery and
performance by the Company of this Agreement and the consummation of the Merger
by the Company are within the Company's corporate powers and have been duly
authorized by all necessary corporate action. This Agreement constitutes a valid
and binding agreement of the Company enforceable against the Company in
accordance with its terms. Copies of the resolutions duly adopted by the
Company's Board of Directors and Genstar, as holder of a majority of the Shares,
authorizing the Merger and the execution and delivery of this Agreement and the
performance by the Company of its obligations hereunder have been furnished to
Novametrix.
 
    SECTION 3.03  GOVERNMENTAL AUTHORIZATION.  The execution, delivery and
performance by the Company of this Agreement and the consummation of the Merger
by the Company require no action by or in respect of, or filing with, any
governmental body, agency, official or authority other than (i) the filing of a
certificate of merger in accordance with Delaware Law; and (ii) compliance with
any applicable requirements of the Hart-Scott-Rodino Antitrust Improvements Act
of 1976 (the "HSR Act"), except where the failure of any such action to be taken
or filing to be made would not have or reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect or prevent
consummation of the transactions contemplated hereby.
 
    SECTION 3.04  NON-CONTRAVENTION.  Except as disclosed on Exhibit 3.04 to the
Company Disclosure Schedule delivered by the Company to Novametrix
simultaneously with the execution and delivery hereof (the "Company Disclosure
Schedule"), the execution, delivery and performance by the Company of this
Agreement and the consummation of the Merger by the Company do not and will not
(i) contravene or conflict with the certificate of incorporation or bylaws of
the Company, (ii) assuming compliance with the matters referred to in Section
3.03, contravene or conflict with or constitute a violation of any provision of
any law, regulation, judgment, injunction, order or decree binding upon or
applicable to the Company or any of its Subsidiaries, (iii) constitute a default
under or give rise to a right of termination, cancellation or acceleration of
any right or obligation of the Company or any of its Subsidiaries or to a loss
of any benefit to which the Company or any of its Subsidiaries is entitled under
any material agreement or other instrument binding upon the Company or any of
its Subsidiaries or any license, franchise, permit or other similar
authorization held by the Company or any of its Subsidiaries, or (iv) result in
the creation or imposition of any Lien (as defined below) on any asset of the
Company or any of its Subsidiaries, except for any occurrences or results
referred to in clauses (ii), (iii) and (iv) which would not have or reasonably
be expected to have, individually or in the aggregate, a Company Material
Adverse Effect or prevent
 
                                      A-6
<PAGE>
consummation of the transactions contemplated hereby. For purposes of this
Agreement, "Lien" means, with respect to any asset, any mortgage, lien, pledge,
charge, security interest or encumbrance or adverse claim of any kind in respect
of such asset.
 
    SECTION 3.05  CAPITALIZATION.  The authorized capital stock of the Company
consists of 300,000 Shares of which 150,000 Shares are voting Class A common
stock, par value $.01 per share ("Class A Shares"), and 150,000 Shares are
non-voting Class B common stock, par value $.01 per share ("Class B Shares"). As
of the date hereof, there are outstanding (v) 89,787 Class A Shares (w) no Class
B Shares, (x) Company Options to purchase an aggregate of 2,559 Shares (none of
which Company Options were then exercisable), (y) Company Warrants to purchase
an aggregate of 8,000 Shares, 2,500 of which were issued to each of Banque
Paribas and the Bank of Nova Scotia and 3,000 of which were issued to BG

of capital stock or other voting securities of the Company, (ii) no securities
of the Company convertible into or exchangeable for shares of capital stock or
voting securities of the Company, and (iii) no options, warrants or other rights
to acquire from the Company, and no obligation of the Company to issue, any
capital stock, voting securities or securities convertible into or exchangeable
for capital stock or voting securities of the Company (the items in clauses (i),
(ii) and (iii) being referred to collectively as the "Company Securities").
Except as disclosed on Exhibit 3.05 to the Company Disclosure Schedule, there
are no outstanding obligations of the Company or any of its Subsidiaries to
repurchase, redeem or otherwise acquire any Company Securities.
 
    SECTION 3.06  SUBSIDIARIES.  (a) Each Subsidiary of the Company is a
corporation duly incorporated, validly existing and in good standing under the
laws of its jurisdiction of incorporation, has all corporate powers and all
governmental licenses, permits, authorizations, consents and approvals required
to carry on its business as now conducted and is duly qualified to do business
as a foreign corporation and is in good standing in each jurisdiction where the
character of the property owned or leased by it or the nature of its activities
makes such qualification necessary, except where failure to have such licenses,
permits, authorizations, consents or approvals or to be so qualified would not
have or reasonably be expected to have, individually or in the aggregate, a
Company Material Adverse Effect. For purposes of this Agreement, "Subsidiary" of
any Person means (i) any corporation or other entity of which securities or
other ownership interests having ordinary voting power to elect a majority of
the board of directors or other persons performing similar functions are
directly or indirectly owned by such Person, and (ii) any partnership of which
such Person is a general partner.
 
    (b) Except as disclosed on Exhibit 3.06(b) to the Company Disclosure
Schedule, all of the outstanding capital stock of each Subsidiary of the Company
is owned by the Company, directly or indirectly, free and clear of any Lien and
free of any other limitation or restriction (including any restriction on the
right to vote, sell or otherwise dispose of such capital stock). There are no
outstanding (i) securities of the Company or any of its Subsidiaries convertible
into or exchangeable for shares of capital stock or other voting securities in
any Subsidiary of the Company, or (ii) options or other rights to acquire from
the Company or any of its Subsidiaries, and no other obligation of the Company
or any of its Subsidiaries to issue, any capital stock or voting securities in,
or any securities convertible into or exchangeable for any capital stock or
voting securities in, any Subsidiary of the Company (the items in clauses (i)
and (ii) being referred to collectively as the "Company Subsidiary Securities").
There are no outstanding obligations of the Company or any of its Subsidiaries
to repurchase, redeem or otherwise acquire any outstanding Company Subsidiary

stockholders of the Company held since January 1, 1993, and (v) all of Andros'
other reports, statements, schedules and registration statements filed with the
Securities and Exchange Commission (the "SEC") since January 1, 1993, and all
materials incorporated therein by reference (the filings referred to in clauses

hereinafter referred to as the "Andros SEC Filings").
 
    (b) As of its filing date, each such report or statement filed pursuant to
the Securities Exchange Act of 1934 and the rules and regulations promulgated
thereunder (the "Exchange Act") complied as to form in all material respects
with the requirements of the Exchange Act and did not contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements made therein, in the light of the circumstances
under which they were made, not misleading.
 
    (c) Each such registration statement and any amendment thereto filed
pursuant to the Securities Act of 1933 and the rules and regulations promulgated
thereunder (the "Securities Act"), as of the date such statement or amendment
became effective, complied as to form in all material respects with the
Securities Act and did not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading.
 
    SECTION 3.08  FINANCIAL STATEMENTS.  The audited consolidated financial

dates thereof and their consolidated results of operations and cash flows for
the periods then ended (subject, in the case of any unaudited interim financial

the aggregate, would have a Company Material Adverse Effect).
 
    SECTION 3.09  PROXY STATEMENT.  None of the information supplied by the
Company for inclusion in the proxy statement relating to the meeting of
Novametrix' stockholders to be held in connection with the Merger (the "Proxy
Statement"), to be filed by Novametrix with the SEC, and any amendments or
supplements thereto, will, at the respective times such documents are filed, and
at the time the Proxy Statement or any amendment or supplement thereto is first
mailed to stockholders of Novametrix, at the time such stockholders vote on
adoption of this Agreement and at the Effective Time, contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements made therein, in the light of the circumstances
under which they were made, not misleading.

    collective bargaining agreement at July 30, 1995 or any lockouts, strikes,

    employees;
 
        (j) any actual or, to the Company's knowledge, threatened dispute

        (k) any actual or, to the Company's knowledge, threatened suspension or

    Company Material Adverse Effect; or
 
        (l) any change in any Federal or state law, rule or regulation
    applicable to the Company or any of its Subsidiaries, or in the

    Adverse Effect.
 
    SECTION 3.11  NO UNDISCLOSED MATERIAL LIABILITIES.  Except as described in
any Andros SEC Filing or on Exhibit 3.11 to the Company Disclosure Schedule,
there are no liabilities of the Company or any of its Subsidiaries of any kind
whatsoever, whether accrued, contingent, absolute, determined, determinable or
otherwise, and there is no existing condition, situation or set of circumstances
which, individually or in the aggregate, have or would reasonably be expected to
have a Company Material Adverse Effect, other than:
 
        (i) liabilities incurred in the ordinary course of business consistent
    with past practices since January 28, 1996, which in the aggregate are not
    material to the Company and its Subsidiaries, taken as a whole; and
 
        (ii) liabilities under this Agreement.
 
    SECTION 3.12  LITIGATION.  Except as described in the Andros 10-K or as
disclosed on Exhibit 3.12 to the Company Disclosure Schedule, there is no
action, suit, investigation or proceeding pending against, or to the knowledge

<PAGE>
which would have or reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect. To the best of the knowledge of
the Company, there is no toxic waste condition or other pollution condition of
any nature, including, without limitation, the presence of asbestos or other
carcinogens, existing at any location leased or owned by the Company or any of
its Subsidiaries which could reasonably be expected to have, individually or in
the aggregate, a Company Material Adverse Effect.
 
    SECTION 3.13  TAXES.  (i) The Company and each of its Subsidiaries have
timely filed all tax returns, statements, reports and forms required to be filed
with any tax authority when due in accordance with all applicable laws except
where the failure to do so would not have or reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect; (ii) no
deficiency in payment of any taxes for any period has been asserted by any
taxing authority which remains unsettled at the date hereof except for
deficiencies which would not have or reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect; and (iii)
neither the Company nor any of its Subsidiaries is liable and it is not
reasonably likely that the Company or any of its Subsidiaries will be liable for
any taxes not reserved against in Andros' consolidated balance sheet as of
January 28, 1996 included in Andros' quarterly report on Form 10-Q for the
fiscal quarter then ended except those which would not have or reasonably be
expected to have, individually or in the aggregate, a Company Material Adverse
Effect.
 
    For purposes of this Agreement, "Code" means the Internal Revenue Code of
1986, as amended; and "tax" or "taxes" means all net income, gross income, gross
receipts, sales, use, ad valorem, transfer, accumulated earnings, personal
holding company, excess profits, franchise, profits, license, withholding,
payroll, employment, excise, severance, stamp, occupation, premium, property or
windfall profits taxes, customs duties or other taxes, fees, assessments or
charges of any kind whatsoever, together with any interest and any penalties,
additions to tax or additional amounts imposed by any taxing authority (domestic
or foreign).
 
    SECTION 3.14  ERISA.  (a) "Employee Plans" shall mean each "employee benefit
plan", as defined in Section 3(3) of the Employee Retirement Income Security Act
of 1974 ("ERISA"), which (i) is subject to any provision of ERISA and (ii) is
maintained, administered or contributed to by the Company or any affiliate (as
defined below) and covers any employee or former employee of the Company or any
affiliate or under which the Company or any affiliate has any liability. Copies
of such plans (and, if applicable, related trust agreements) and all amendments
thereto and written interpretations thereof have been furnished to Novametrix.
For purposes of this Section, "affiliate" of any Person means any other Person
which, together with such Person, would be treated as a single employer under
Section 414 of the Code. No Employee Plan individually or collectively
constitutes a "defined benefit plan" as defined in Section 3(35) of ERISA.
 
    (b) No Employee Plan constitutes a "multi-employer plan", as defined in
Section 3(37) of ERISA, and no Employee Plan is maintained in connection with
any trust described in Section 501(c)(9) of the Code. No Employee Plan is
subject to Title IV of ERISA. Neither the Company nor any of its affiliates has
incurred, nor has reason to expect to incur, any liability under Title IV of
ERISA arising in connection with the termination of, or complete or partial
withdrawal from, any plan previously covered by Title IV of ERISA that would
have, or reasonably be expected to have, individually or in the aggregate, a
Company Material Adverse Effect. Nothing done or omitted to be done and no
transaction or holding of any asset under or in connection with any Employee
Plan has or will make the Company or any of its Subsidiaries or any officer or
director of the Company or any of its Subsidiaries subject to any liability
under Title I of ERISA or liable for any tax pursuant to Section 4975 of the
Code that would have, or reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect.
 
    (c) Except as disclosed on Exhibit 3.14 to the Company Disclosure Schedule
and except to the extent it would not have, or reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect, (i) each
Employee Plan which is intended to be qualified under Section 401(a) of the Code
is so qualified and has been so qualified during the period from its adoption to
date, and each trust
 
                                      A-10
<PAGE>
forming a part thereof is exempt from tax pursuant to Section 501(a) of the
Code, and (ii) each Employee Plan has been maintained in compliance with its
terms and with the requirements prescribed by any and all statutes, orders,
final rules and final regulations, including but not limited to, ERISA and the
Code, which are applicable to such Employee Plan.
 
    (d) Except to the extent it would not have, or reasonably be expected to
have, individually or in the aggregate, a Company Material Adverse Effect, there
is no contract, agreement, plan or arrangement covering any employee or former
employee of the Company or any of its Subsidiaries that, individually or
collectively, could give rise to the payment of any amount that would not be
deductible due to Sections 162(m) or 280G of the Code.
 
    (e) "Benefit Arrangement" of any party shall mean each employment, severance
or other similar contract, arrangement or policy and each plan or arrangement
(written or oral) providing for compensation, bonus, profit-sharing, stock
option, or other stock related rights or other forms of incentive or deferred
compensation, vacation benefits, insurance coverage (including any self-insured
arrangements), health or medical benefits, disability benefits, workers'
compensation, supplemental unemployment benefits, severance benefits and
post-employment or retirement benefits (including compensation, health or
medical insurance or other benefits) which (i) is not an Employee Plan, (ii) is
entered into, maintained or contributed to, as the case may be, by such party or
any of its affiliates and (iii) covers any employee or former employee of such
party or any of its affiliates. Copies or descriptions of the Benefit
Arrangements of the Company have been furnished to Novametrix. Exhibit 3.14(e)
to the Company Disclosure Schedule sets forth all outstanding Company Options as
of the date hereof, including the applicable exercise price with respect

duly incorporated, validly existing and in good standing under the laws of the
State of Delaware, and has all corporate powers and all governmental licenses,
permits, authorizations, consents and approvals required to carry on its
business as now conducted except where the failure to do so would not have or
reasonably be expected to have, individually or in the aggregate, a material
adverse effect on the financial condition, business, assets or results of
operations of Novametrix and its Subsidiaries taken as a whole (a "Novametrix
Material Adverse Effect"). Novametrix is duly qualified to do business as a
foreign corporation and is in good standing in each jurisdiction where the
character of the property owned or leased by it or the nature of its activities
makes such qualification necessary, except for those jurisdictions where the
failure to be so
 
                                      A-13
<PAGE>
qualified would not have or reasonably be expected to have, individually or in
the aggregate, a Novametrix Material Adverse Effect. Novametrix has heretofore
delivered to the Company true and complete copies of Novametrix' certificate of
incorporation and bylaws as currently in effect. Since the date of its
incorporation, the Merger Subsidiary has not engaged in any activities other
than in connection with or as contemplated by this Agreement.

Merger. This Agreement constitutes a valid and binding agreement of Novametrix
and the Merger Subsidiary enforceable against Novametrix and the Merger
Subsidiary in accordance with its terms.
 
    SECTION 4.03  GOVERNMENTAL AUTHORIZATION.  The execution, delivery and
performance by Novametrix and the Merger Subsidiary of this Agreement and the

Law; (ii) compliance with any applicable requirements of the HSR Act, the
Exchange Act and the Securities Act; (iii) compliance with the applicable
requirements of the Nasdaq National Market; and (iv) compliance with any
applicable state securities or Blue Sky laws, except where the failure of any
such action to be taken or filing to be made would not have or reasonably be
expected to have, individually or in the aggregate, a Novametrix Material
Adverse Effect or prevent consummation of the transactions contemplated hereby.
 
    SECTION 4.04  NON-CONTRAVENTION.  Except as disclosed on Exhibit 4.04 to the

the Merger Subsidiary of this Agreement and the consummation of the Merger by
the Merger Subsidiary do not and will not (i) contravene or conflict with the
certificate of incorporation or bylaws of Novametrix or the Merger Subsidiary,
(ii) assuming compliance with the matters referred to in Section 4.03,
contravene or conflict with or constitute a violation of any provision of any
law, regulation, judgment, injunction, order or decree binding upon or
applicable to Novametrix or any of its Subsidiaries, (iii) constitute a default
under or give rise to a right of termination, cancellation or acceleration of
any right or obligation of Novametrix or any of its Subsidiaries or to a loss of
any benefit to which Novametrix or any of its Subsidiaries is entitled under any
material agreement or other instrument binding upon Novametrix or any of its
Subsidiaries or any license, franchise, permit or other similar authorization
held by Novametrix or any of its Subsidiaries, or (iv) result in the creation or
imposition of any Lien on any asset of Novametrix or any of its Subsidiaries,
except for any occurrences or results referred to in clauses (ii), (iii) and
(iv) which would not have or reasonably be expected to have, individually or in
the aggregate, a Novametrix Material Adverse Effect or prevent consummation of
the transactions contemplated hereby.

expected to have, individually or in the aggregate, a Novametrix Material

to have, individually or in the aggregate, a Novametrix Material Adverse Effect,
there is no contract, agreement, plan or arrangement covering any employee or
former employee of Novametrix or any of its Subsidiaries that, individually or
collectively, could give rise to the payment of any amount that would not be
deductible due to Sections 162(m) or 280G of the Code.

of such transactions or the termination of such employee within a specified time
period after such transactions.

amendment to, written interpretation or announcement (whether or not written) by

participation or coverage under, any Novametrix Employee Plan or Benefit
Arrangement of Novametrix which in the aggregate would increase the per employee
expense of maintaining such Novametrix Employee Plan or Benefit Arrangement of
Novametrix above the level of the expense incurred on a per employee basis in
respect thereof for the six months ended October 29, 1995 except to the extent,
with respect to all employees, as would not have, or reasonably be expected to
have, individually or in the aggregate, a Novametrix Material Adverse Effect.

rights listed are all such rights necessary to the conduct of the business of
Novametrix and its Subsidiaries as currently conducted; no adverse claim has
been made and no dispute has arisen with respect to any of the said proprietary
rights; and the operations of the business of Novametrix and its Subsidiaries
and the use by Novametrix or its Subsidiaries of such proprietary rights do not
involve infringement or claimed infringement of any patent, trademark, service
mark, tradename, copyright, license or similar right. Novametrix has taken
reasonable measures to maintain the confidentiality of the processes and

of which to Novametrix is dependent upon the maintenance of the confidentiality
thereof. Neither Novametrix nor any of its Subsidiaries has licensed or

cancellation of any of the Novametrix Permits is pending or, to the knowledge of
any of the officers of Novametrix or any of its Subsidiaries, threatened, except

Novametrix Disclosure Schedule. Except as disclosed on Exhibit 4.19(a)(i) to the
Novametrix Disclosure Schedule, neither Novametrix nor any of its Subsidiaries

licenses, registrations, approvals, permits and device listings. Exhibit

indirectly, (i) take any action to solicit, initiate or encourage any Novametrix
Acquisition Proposal (as defined below) or (ii) engage in negotiations with, or
disclose any nonpublic information relating to Novametrix or any of its
Subsidiaries or afford access to the properties, books or records of Novametrix
or any of its Subsidiaries to, any Person that may be considering making, or has
made, a Novametrix Acquisition Proposal. Nothing contained in this Section
6.03(a) or any other provision of this Agreement shall prevent the Board of
Directors of Novametrix, after receiving an opinion of outside counsel to the
effect that the Board is required to do so in order to discharge properly its
fiduciary duties, from considering, negotiating, approving and recommending to
the stockholders of Novametrix an unsolicited bona fide written Novametrix
Acquisition Proposal which the Board determines in good faith (after
consultation with its financial advisors) is made by a person financially
capable of consummating such Novametrix Acquisition Proposal (any such
Novametrix Acquisition Proposal being referred to herein as a "Superior
Novametrix Proposal"). For purposes of this Agreement, "Novametrix Acquisition
Proposal" means any offer or proposal for, or any indication of interest in, a
merger or other business combination involving Novametrix or any of its
Subsidiaries or the acquisition of any equity interest in, or a substantial
portion of the assets of, Novametrix or any of its Subsidiaries, other than the
transactions contemplated by this Agreement.

    (b) Novametrix will promptly notify the Company after receipt of any
Novametrix Acquisition Proposal or any indication that any Person is considering
making a Novametrix Acquisition Proposal or any request for nonpublic
information relating to Novametrix or any of its Subsidiaries or for access to
the properties, books or records of Novametrix or any of its Subsidiaries by any
Person that may be considering making, or has made, a Novametrix Acquisition
Proposal. Novametrix shall immediately cease and cause to be terminated any
existing discussions or negotiations with any parties (other than the Company)
conducted heretofore with respect to any of the foregoing.
 
    (c) If the Board of Directors of Novametrix receives a request for material
nonpublic information by a party who makes a Superior Novametrix Proposal, then,
and only in such case, Novametrix may, subject to the execution of a
confidentiality agreement substantially similar to that then in effect between
the Company and Novametrix, provide such party with access to information
regarding Novametrix. Novametrix agrees not to release any third party from any
confidentiality or standstill agreement to which Novametrix is a party.
 
    SECTION 6.04  OBLIGATIONS OF MERGER SUBSIDIARY.  Novametrix will take all
action necessary to cause the Merger Subsidiary to perform its obligations under

forth in this Agreement.

at or prior to the Effective Time and (b) the Surviving Corporation shall
indemnify, defend and hold harmless to the fullest extent permitted by law the
present and former officers and directors of the Company and its Subsidiaries
against all losses, claims, damages and liability in respect of acts or
omissions occurring at or prior to the Effective Time. Novametrix shall cause
the Surviving Corporation (and its successors) to establish and maintain
provisions in its certificate of incorporation and by-laws concerning the
indemnification and exoneration of the Company's former and present officers,
directors, employees and agents that are no less favorable to those persons than
the provisions of the Company's certificate of incorporation and by-laws in
effect on the date hereof.
 
    SECTION 6.06  INCLUSION IN NASDAQ NATIONAL MARKET.  Novametrix shall use its
reasonable best efforts to cause the shares of Novametrix Common Stock to be
issued in the Merger (including the Underlying Shares) to be approved for
inclusion in the Nasdaq National Market subject to official notice of issuance,
prior to the Effective Time.
 
    SECTION 6.07  NOTICE OF CERTAIN EVENTS.  Each of Novametrix and the Merger
Subsidiary shall promptly notify the Company of:
 
        (i) any notice or other communication from any Person alleging that the
    consent of such Person (or another Person) is or may be required in
    connection with the transactions contemplated by this Agreement;
 
        (ii) any notice or other communication from any governmental or
    regulatory agency or authority in connection with the transactions
    contemplated by this Agreement; and
 
       (iii) any actions, suits, claims, investigations or proceedings commenced
    or, to the best of its knowledge threatened against, relating to or
    involving or otherwise affecting it or any of its Subsidiaries which, if

    disclosed pursuant to Section 4.11 or which relate to the consummation of
    the transactions contemplated by this Agreement.

with one another (a) in connection with the preparation of the Proxy Statement,

to any material contracts, in connection with the consummation of the
transactions contemplated by this Agreement and (c) in seeking any such actions,
consents, approvals or waivers or making any such filings, furnishing
information required in connection therewith or with the Proxy Statement and

with each other before issuing any press release or making any public statement
with respect to this Agreement and the transactions contemplated hereby and,
except as may be required by applicable law or any listing agreement with any
national securities exchange or interdealer quotation system upon the advice of
counsel (in which case only reasonable efforts to consult with the other party
are required), will not issue any such press release or make any such public
statement without the prior consent of the other party, which consent shall not
be unreasonably withheld or delayed.

actions and things to vest, perfect or confirm of record or otherwise in the
Surviving Corporation any and all right, title and interest in, to and under any
of the rights, properties or assets of the Company acquired or to be acquired by
the Surviving Corporation as a result of, or in connection with, the Merger.
 
    SECTION 7.05  STOCKHOLDER MEETING.  Novametrix shall cause a meeting of its
stockholders (the "Stockholder Meeting") to be duly called and held, or action
to be taken by written consent without a Stockholder Meeting, as soon as
reasonably practicable for the purpose of voting on the approval and adoption of
this Agreement and the Merger. The Directors of Novametrix shall, unless any of
such respective Directors determines in good faith after consultation with and
based upon a written opinion of outside legal counsel that they are otherwise
required in accordance with their fiduciary duties, recommend approval and
adoption of this Agreement and the Merger by Novametrix' stockholders. In
connection with such meetings, Novametrix will use its best efforts to obtain
the necessary approvals by its stockholders of this Agreement, the transactions
contemplated hereby and such other matters as are contemplated by the terms of
this Agreement or required by Delaware Law, and will otherwise comply with all
legal requirements applicable to such meetings.
 
    SECTION 7.06  PREPARATION OF THE PROXY STATEMENT.  Novametrix and the
Company shall promptly prepare and Novametrix shall file with the SEC a
preliminary version of the Proxy Statement and will use their best efforts to
respond to the comments of the SEC in connection therewith and to furnish all
information required to prepare the definitive Proxy Statement. Novametrix shall
also take any action (other than qualifying to do business in any jurisdiction
in which it is not now so qualified or filing a general consent to service of
process in any jurisdiction) required to be taken under any applicable state
 
                                      A-26

information concerning the Company and the holders of Shares as may be
reasonably requested in connection with any such action. Novametrix will cause
the Proxy Statement to be mailed to its stockholders, and if necessary, after

amended, supplemented or supplemental proxy materials and, if required in
connection therewith, resolicit proxies.

    publicly announced, and not withdrawn, a proxy contest, tender offer,
    exchange offer, merger or other Novametrix Acquisition Proposal (the
    "Pre-Termination Transaction"), and, within 12 months of such vote,
    Novametrix shall enter into, or be the subject of, a transaction which would

    Transaction").
 
    (c) The Fees shall be paid within one business day after the first to occur
of the events described in Section 9.03(a), (b)(i) or (b)(ii), or Novametrix'

                          AGREEMENT AND PLAN OF MERGER
 
    AMENDMENT NO. 1 dated as of October 18, 1996, to the AGREEMENT AND PLAN OF
MERGER dated as of July 29, 1996, (the "Merger Agreement") among Andros Holdings
Inc., a Delaware corporation (the "Company"), Novametrix Medical Systems Inc., a
Delaware corporation ("Novametrix"), and Novametrix Acquisition Corp., a
Delaware corporation and a wholly owned subsidiary of Novametrix ("Merger
Subsidiary").
 
    WHEREAS, the Company, Novametrix and Merger Subsidiary have entered into the
Merger Agreement; and
 
    WHEREAS, the Company, Novametrix and Merger Subsidiary desire, through this
Amendment No. 1, to amend the Merger Agreement.
 
    NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein and in
the Merger Agreement, the parties hereto agree as follows:
 
    1.  Section 1.02(b) of the Merger Agreement is hereby amended by deleting
the word "and" at the end of such Section.
 
    2.  Section 1.02(c) of the Merger Agreement is hereby amended by replacing
the period at the end of such Section with "; and", by deleting subsection
1.02(c)(i)(x) of such Section in its entirety and by substituting in lieu
thereof the following:
 
       "(x) .6129032 (such number being hereinafter referred to as the "Base
           Number" and such number, as it may be adjusted pursuant to Section
           1.02(d), being hereinafter referred to as the "Adjusted Base Number")
           multiplied by the number of shares of Novametrix Common Stock
           outstanding immediately prior to the Effective Time (assuming
           conversion of all then outstanding shares of preferred stock, $1.00
           par value (the "Novametrix Preferred Stock"), of Novametrix) divided
           by ..."
 
    3.  A new Section 1.02(d) is hereby inserted in the Merger Agreement to read
as follows:
 
       "(d) in the event that either (x) the Net Revenues of the Company (as
           defined below) for the fiscal year ending May 3, 1998 ("FY1998")
           shall exceed $48,900,000 or (y) the EBITDA of Novametrix (as defined
           below) for FY1998 shall exceed $16,300,000, each holder of Shares
           outstanding immediately prior to the Effective Time shall be entitled
           to receive for each Share so held a number of additional shares of
           Novametrix Common Stock (the "Earn-Out Shares") computed by
           subtracting (x) the Exchange Number determined by using the Base
           Number from (y) the Exchange Number determined by using the Adjusted
           Base Number. The Adjusted Base Number shall be a number, calculated
           to seven decimal places, equal to a fraction (I) the numerator of
           which is 38% plus the Adjustment Factor (as defined below) and (II)
           the denominator of which is 62% minus the Adjustment Factor. The
           Adjustment Factor shall be equal to 1% multiplied by the greater of
           (x) the quotient of (A) the amount by which the Net Revenues of the
           Company for FY1998 exceed $48,900,000 divided by (B) $1,700,000 and
           (y) the quotient of (C) the amount by which the EBITDA of Novametrix
           for FY1998 exceeds $16,300,000 divided by (D) $660,000, but in no
           event shall the Adjusted Base Number be greater than .7543860.
 
           The Net Revenues of the Company shall be determined in accordance
           with generally accepted accounting principles and shall be derived
           from the audited consolidated financial statements of the Company for
           FY1998. For purposes of determining the Net Revenues of the Company,
           any net revenues of businesses acquired by the Company subsequent to
           the date hereof shall be eliminated. The EBITDA of Novametrix shall
           be determined from the audited consolidated statement of income of
           Novametrix for FY1998 and shall be defined as
 
                                      A-33
<PAGE>
           net revenues minus the sum of cost of products sold, research and
           development expense and selling, general and administrative expense
           plus depreciation and amortization expense to the extent that these
           items are included in cost of products sold, research and product
           development expense and selling, general and administrative expense.
           The EBITDA of Novametrix shall be adjusted to eliminate the EBITDA
           resulting from any businesses acquired by Novametrix subsequent to
           the date hereof, compensation expense attributable to the exercise of
           stock options, gains or losses on the sale or disposition of
           substantial assets or liabilities and any restructuring or other
           unusual charges or costs incurred by Novametrix during FY1998. In the
           event that at any time prior to the end of FY1998 all or a
           substantial portion of the assets and business of the Company or
           Novametrix shall have been transferred to another entity or entities,
           then prior to such transfer the Board of Directors of Novametrix
           shall determine the amount of the allocable portion of the Net
           Revenues of the Company and EBITDA of Novametrix that shall be
           (utilizing the historical period to date net revenues and EBITDA and
           budgeted and or forecasted future period revenues and EBITDA
           attributable to such assets or business) attributable to such assets
           and business during FY1998, and the amount so determined by the Board
           shall be included in the Net Revenues of the Company and EBITDA of
           Novametrix for FY1998 for purposes of determining the Adjusted Base
           Number. In the event of (i) a consolidation or merger of Novametrix
           with or into another corporation in which Novametrix is not the
           surviving corporation, or (ii) a merger in which Novametrix is the
           surviving corporation but the shares of Novametrix's capital stock
           outstanding immediately prior to the merger are converted by virtue
           of the merger into other property, whether in the form of securities,
           cash or otherwise, or (iii) any sale of all or substantially all of
           Novametrix' assets to another corporation (each of the events
           described in clauses (i), (ii) or (iii) above being a "Subsequent
           Combination"), then, as a condition of such Subsequent Combination,
           lawful and adequate provision will be made whereby each holder of the
           right to receive Earn-Out Shares will thereafter have the contingent
           right to receive on the Adjustment Date (as hereinafter defined) the
           kind of stock and other securities and property (including, without
           limitation, cash) paid in connection with the Subsequent Combination
           which, based upon the fair market value of such stock and other
           securities and property (including, without limitation, cash) on the
           Adjustment Date, would have a value equal to the portion of such
           Earn-Out Shares which would have been paid prior to the Subsequent
           Combination."
 
    4.  A new Section 1.03(g) is hereby inserted in the Merger Agreement to read
as follows:
 
       "(g) If Novametrix shall become obligated to issue Earn-Out Shares
           pursuant to Section 1.02(d), Novametrix shall deliver, or arrange to
           have delivered, within 10 business days after it shall have received
           its audited consolidated financial statements for FY1998 from its
           independent public accountants (the date of such delivery is
           hereinafter referred to as the "Adjustment Date"), certificates(s)
           representing the number of Earn-Out Shares issuable to each holder
           (an "exchanging holder") of Shares as of the Effective Date that
           exchanged such Shares for shares of Novametrix Common Stock (and cash
           in lieu of fractional shares and Rights) pursuant to Section 1.03(a)
           registered in the name of the person to whom such shares of
           Novametrix Common Stock (and cash in lieu of fractional shares) and
           Rights were issued at the address of such person as it appears on the
           records of Novametrix. Novametrix shall not issue fractional Earn-Out
           Shares to any exchanging holder. The number of Earn-Out Shares that
           each exchanging holder shall be entitled to receive shall be rounded
           down to the nearest whole share. Novametrix has authorized the
           issuance of and will hold in reserve the Earn-Out Shares issuable
           pursuant to this Section 1.03(g) and Sections 1.04(e) and 1.06(f)."
 
    5.  A new Section 1.04(e) is hereby inserted in the Merger Agreement to read
as follows:
 
       "(e) In the event that the holder (an "exercising holder") of any Company
           Option or Company Warrant shall exercise (in whole or in part) such
           Company Option or Company Warrant prior to the Adjustment Date and an
           Adjusted Base Number is subsequently in effect
 
                                      A-34
<PAGE>
           pursuant to Section 1.02(d), on the Adjustment Date Novametrix shall
           issue to such exercising holder a number of Earn-Out Shares (each
           rounded down to the nearest whole share) equal to the difference
           between (x) the number of shares of Novametrix Common Stock which
           would have been issued to such exercising holder had such Company
           Option or Company Warrant (or portion thereof), as applicable, been
           exercised after such Adjusted Base Number had been in effect and (y)
           the number of shares of Novametrix Common Stock actually issued upon
           the exercise of such Company Option or Company Warrant (or portion
           thereof), as applicable."
 
    6.  Section 1.06(c) of the Merger Agreement is hereby amended by deleting
subsection 1.06(c)(c)(i) of such Section in its entirety, and by substituting in
lieu thereof the following:
 
       "(i) the Base Number (or if there shall be an Adjusted Base Number in
           effect, the Adjusted Base Number) multiplied by the number of shares
           of Novametrix Common Stock issued by Novametrix pursuant to warrants
           or options to acquire shares of Novametrix Common Stock outstanding
           immediately prior to the Effective Time (but excluding any such
           shares issued upon conversion of the Novametrix Preferred Stock) and
           ..."
 
    7.  A new Section 1.06(f) is hereby inserted in the Merger Agreement to read
as follows:
 
       "(f) In the event that shares of Novametrix Common Stock are issued to
           the holders of Rights with respect to one or more Antidilution Events
           prior to the Adjustment Date and an Adjusted Base Number is
           subsequently in effect pursuant to Section 1.02(d), on the Adjustment
           Date Novametrix shall issue to each holder of Rights a number of
           Earn-Out Shares (rounded down to the nearest whole share) equal to
           the difference between (x) the aggregate number of shares of
           Novametrix Common Stock which would have been issued to such holder
           had the Adjusted Base Number been in effect with respect to all
           Antidilution Events occurring prior to the Adjustment Date and (y)
           the aggregate number of shares of Novametrix Common Stock actually
           issued to such holder with respect to all such Antidilution Events."
 
    8.  The parties hereby agree that the matters set forth in the disclosure
letter delivered by the Company to Novametrix simultaneously with the execution
and delivery hereof shall not be deemed to be breaches of the representations
and warranties of the Company contained in the Merger Agreement, and,
accordingly, the existence thereof shall not permit Novametrix (a) to fail to
(nor permit the Merger Subsidiary to fail to) fulfill their respective
obligations under the Merger Agreement to consummate the Merger pursuant to
Section 8.02(i) thereof or (b) to terminate the Merger Agreement pursuant to
Section 9.01(vi) thereof.
 
    9.  All references in the Merger Agreement to the "Agreement" shall be to
the Merger Agreement as amended by this Amendment No. 1.
 
    10. Except as expressly set forth herein, all of the terms and conditions of
the Merger Agreement shall remain unaffected by this Amendment No. 1 and shall
remain in full force and effect.
 
    11. This Amendment No. 1 may be signed in any number of counterparts, each
of which shall be an original, with the same effect as if the signatures thereto
and hereto were upon the same instrument. This Amendment No. 1 shall become
effective when each party hereto shall have received counterparts hereof signed
by all of the other parties hereto. This Amendment No. 1 shall be governed by
and construed in
 
                                      A-35
<PAGE>
accordance with the laws of the State of Delaware, without regard to any
conflict of laws principles of such State which would apply the laws of any
other jurisdiction.
 
    IN WITNESS WHEREOF, the parties hereto have caused this Amendment No. 1 to
be duly executed by their respective authorized officers as of the day and year
first above written.

Gentlemen:
 
You have requested our opinion as to the fairness to Novametrix Medical Systems
Inc. ("Novametrix") and its stockholders, from a financial point of view, and as
of the date hereof, of the Exchange Ratio (as defined below) in the proposed
merger of Andros Incorporated ("Andros") with and into Novametrix pursuant to
the merger agreement dated July 29, 1996 and as amended as of October 18, 1996
(the "Merger Agreement"). Under the terms of the Merger Agreement, a wholly
owned subsidiary of Novametrix will merge with and into Andros, and thereafter
Andros will become a wholly owned subsidiary of Novametrix in accordance with
the Merger Agreement (the "Merger"). Pursuant to the Merger, all of the issued
and outstanding shares of Andros will be converted into the right to receive i)
shares of Novametrix common stock (the "Common Stock") consisting in the
aggregate of 38% of the shares of Common Stock outstanding immediately after the
Effective Time (as defined in the Merger Agreement) computed as follows a) each
issued and outstanding share of Andros will be converted into a right to receive
shares of Common Stock equal to .6129032 multiplied by the number of shares of
Common Stock then outstanding (assuming conversion of the November preferred
stock) divided by the number of shares of Andros common stock outstanding
(assuming the exercise in full of all then outstanding Andros options and
warrants) and b) one contingent right to receive Common Stock under certain
antidilution events equal to .6129032 multiplied by the number of shares of
Common Stock issued pursuant to Novametrix warrants or options to acquire shares
of Common Stock outstanding immediately prior to the Effective Time subject to
adjustment based on cancellation or expiration of Andros options and warrants
and ii) up to an additional 5% of the shares of Common Stock (based upon the
capitalization of Novametrix immediately after the Merger) in the event that
Andros' revenues or Novametrix' consolidated EBITDA for the fiscal year ending
May 3, 1998 exceed certain targets as set forth in Section 1.02 (d) of the
Merger Agreement (collectively, the "Exchange Ratio"). The Merger is intended to
qualify as a tax-free reorganization. The terms and conditions of the Merger are
more fully set forth in the Merger Agreement.
 
Tucker Anthony Incorporated ("Tucker Anthony"), as part of its investment
banking business, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated underwritings
and private placements and for corporate and other purposes. Tucker Anthony has
acted as Novametrix' financial advisor in connection with, and has participated
in the negotiations leading to, the proposed Merger. Tucker Anthony will receive
fees for our services as financial advisor and for rendering this opinion, a
substantial portion of which is contingent upon the closing of the Merger. In
the ordinary course of our business, Tucker Anthony may actively trade the
securities of Novametrix for our own account and for the accounts of customers
and, accordingly, may at any time hold a long or short position in such
securities.
 
In connection with our opinion, we have, among other things:
 
(i) reviewed the Merger Agreement and related documents;
<PAGE>
(ii) reviewed certain publicly available financial information for Novametrix
and Andros;
 
(iii) reviewed financial information on Novametrix and Andros furnished to us by
both companies, including certain internal financial analyses and forecasts
prepared by Novametrix and Andros managements;
 
(iv) held discussions with the management of Novametrix and Andros concerning
the businesses, past and current business operations, financial condition and
future prospects of both companies, independently and combined, including
certain information prepared jointly by the managements of Novametrix and Andros
concerning potential cost savings and synergies that could result from the
Merger;
 
(v) reviewed the stock price and trading history of Novametrix;
 
(vi) analyzed certain publicly available information of companies we deemed
comparable or otherwise relevant to our inquiry and compared Novametrix and
Andros from a financial point of view with these companies;
 
(vii) compared the financial terms of the Merger with other business
combinations which we deemed comparable or otherwise relevant to our inquiry;
 
(viii) prepared a discounted cash flow analysis of Novametrix and Andros;
 
(ix) reviewed the contribution by each company to proforma combined revenue,
gross profit, earnings before interest, taxes, depreciation and amortization,
earnings before interest and taxes and net income;
 
(x) analyzed the proforma earnings per share of the combined company;
 
(xi) discussed with senior management of Novametrix their view of the strategic
rationale for the Merger and the benefits of the Merger to Novametrix;
 
(xii) discussed with senior management of Novametrix and its counsel their view
of the likely outcomes of pending, threatened and possible claims against
Novametrix and Andros; and
 
(xiii) conducted such other financial studies and analysis and reviewed such

In our review and analysis and in arriving at our opinion we have assumed and
relied upon the accuracy and completeness of all the financial information
publicly available or provided to us by Novametrix and Andros and have not
attempted to verify any of such information. We did not make or obtain an
independent evaluation or appraisals of any assets or liabilities of Novametrix,
Andros or any of their respective subsidiaries. We have also relied upon,
without independent certification, Novametrix' management's assessment of the
validity of Novametrix' and Andros' products and technology. We have assumed (i)
the financial projections of Novametrix and Andros provided to us have been
reasonably prepared on a basis reflecting the best currently available estimates
and judgments of Novametrix and Andros managements as to future financial
performance and (ii) that such projections will be realized in the amounts and
time periods currently estimated by the respective managements. We have also
relied upon estimates and judgments of Novametrix and Andros as to the future
performance of both companies, including the cost savings and synergies
resulting from the Merger. We have also relied upon Novametrix' management's
assessment of the likely outcomes of pending, threatened and possible claims
against Novametrix and Andros. We have also assumed, with your consent, that the
Merger will be accounted for as a purchase transaction which will include a
substantial write-off of in-process research and development under generally
accepted accounting principles. Tucker Anthony's opinion is necessarily based
upon market, economic and other conditions that exist and can be evaluated as of
the date hereof.

Based upon and subject to the foregoing considerations, it is our opinion that,
as of the date hereof, the Exchange Ratio is fair to Novametrix and its
stockholders from a financial point of view.

    REGISTRATION RIGHTS AGREEMENT dated as of            , 1996 (this
"Agreement") among Novametrix Medical Systems Inc., a Delaware corporation (the
"Corporation"), Genstar Capital Partners II, L.P., a Delaware limited
partnership ("Genstar"), and the other persons listed on Exhibit A hereto
(collectively, including Genstar, the "Stockholders").
 
                              W I T N E S S E T H:
 
    WHEREAS, the Corporation, Novametrix Acquisition Corp., a Delaware
corporation (the "Merger Subsidiary"), and Andros Holdings Inc., a Delaware
corporation ("Andros"), are entering into an Agreement and Plan of Merger dated
as of the date hereof (the "Merger Agreement") pursuant to which the Merger
Subsidiary is to be merged (the "Merger") with and into Andros, Andros is to
become a wholly owned subsidiary of the Corporation and the Corporation is to
issue shares of its common stock, par value $.01 per share ("Common Stock"), to
the Stockholders; and
 
    WHEREAS, a condition to consummation of the Merger is that the Corporation
provides the Stockholders with certain registration rights and the parties wish
to make the representations and enter into the covenants set forth herein.
 
    NOW, THEREFORE, in consideration of the mutual benefits to be derived and
the conditions and promises herein contained, and intending to be legally bound
hereby, the parties hereto agree as follows:
 
    1.  REGISTRATION OF COMMON STOCK.  (a) At any time after the end of the
nine-month period beginning on the date of the Effective Time (as defined in the
Merger Agreement), the Stockholder Representative (as defined in Section 3(a))
shall have the right to request that the Corporation effect the registration
under the Securities Act of 1933, as amended (the "Securities Act"), of any or
all shares of Common Stock issued in the Merger or constituting Underlying
Shares (as defined in the Merger Agreement) and beneficially owned by the
Stockholders (the shares of Common Stock requested to be registered under this
subsection (a) are hereinafter collectively referred to as the "Demand
Registration Shares"); provided that each request by the Stockholder
Representative hereunder shall (x) specify the intended method of disposition
thereof by the Stockholders and (y) shall cover in the aggregate at least a
number of shares of Common Stock equal to 20% of the number of shares of Common
Stock (as such number shall be appropriately adjusted for stock dividends, stock
splits and similar events) issued in the Merger and beneficially owned by the
Stockholders immediately after the Effective Time (the "Original Shares"). The
Corporation shall not be obligated to file and cause to become effective more
than two registration statements in which Demand Registration Shares are
registered pursuant to this subsection (a) and there shall be at least a
six-month period between such filings under this subsection (a). The
Stockholders' rights under this subsection (a) shall terminate upon the earlier
to occur of (1) the tenth anniversary of the date hereof and (2) the date on
which at least 80% of the aggregate number of Original Shares and Underlying
Shares shall have been registered under the Securities Act.
 
    (b) In the event that any of the Stockholders, if they have the right to do
so, exercises its rights under subsection (a) of this Section 1, the Corporation
shall use its reasonable best efforts to cause the sale of the Demand
Registration Shares to be registered under the Securities Act and to effect and
to comply with all such regulatory qualifications, compliances and requirements
as may be necessary to permit the sale or other transfer of such Demand
Registration Shares, in the manner described in such request, including, without
limitation, qualifications under applicable blue sky or other state securities
laws (provided that the Corporation shall not be required in connection
therewith to qualify as a foreign corporation or to execute a general consent to
service of process in any state); provided, however, that (i) if the legend set
forth in Section 2(a) is or has been removed from the certificates evidencing
any of the Demand Registration Shares pursuant to Section 2(b), then the
Corporation shall not be required to take any action with respect to the
registration of such Demand Registration Shares or other steps contemplated
hereby in connection therewith and such Demand Registration Shares shall not be
deemed included in a registration request for purposes of the requirement set
forth in clause (y) of Section 1(a) and (ii) the Corporation shall have the
right to delay such registration for one period of 90 days in any twelve-month
period by written notice to the Stockholder Representative in the event that the
Board of Directors of the Corporation determines in
 
                                      D-1
<PAGE>
good faith that such delay is in the best interests of the Corporation, provided
that the Stockholder Representative shall be entitled to withdraw such request
within 30 days of receipt of such notice and if such request is withdrawn, such
registration shall not constitute a registration to which the Stockholders are
entitled pursuant to this Section 1.
 
    (c) In the event that, at any time or from time to time, the Corporation
proposes to register the sale of any shares of Common Stock to be issued by the
Corporation or sold by any holder of shares of Common Stock (the "Registration
Shares") under the Securities Act pursuant to a registration statement to be
filed after the end of the nine-month period beginning after the date of the
Effective Time, including, without limitation, pursuant to Section 1(a) above
but other than pursuant to a registration statement on Forms S-4 or S-8, or any
successor to such Forms, for the purpose of the issuance, sale or other transfer
of the Registration Shares by the Corporation or such holder, the Corporation
shall mail or deliver to each of the Stockholders at least 15 days prior to the
filing of the registration statement covering such Registration Shares, a
written notice (a "Registration Notice") of its intention so to register the
Registration Shares, and specifying the date by which the Supplemental Notice
referred to in Section 1(d) below must be returned to the Corporation.
 
    (d) In the event that a Registration Notice shall have been so mailed or
delivered, each of the Stockholders, at such person's election, may mail or
deliver to the Corporation a written notice or notices (a "Supplemental Notice")
(i) specifying the number of shares of Common Stock issued in the Merger and
Underlying Shares (collectively "Supplemental Registration Shares") proposed to
be sold or otherwise transferred by such Stockholder, (ii) describing the
proposed manner of sale or other transfer thereof and (iii) requesting the
registration thereof under the Securities Act; provided, however, that such
Supplemental Notice shall be so mailed or delivered by any Stockholder not more
than 10 days after the date of the Registration Notice.
 
    (e) From and after receipt of a Supplemental Notice, the Corporation shall,
subject to the prior sale or other transfer of some or all of such Registration
Shares and subject to the provisions of subsection (a) above, use its reasonable
best efforts to cause the Supplemental Registration Shares specified in such
Supplemental Notice to be registered under the Securities Act and to effect and
to comply with all such regulatory qualifications and requirements as may be
necessary to permit the sale or other transfer of such Supplemental Registration
Shares in the manner described in such Supplemental Notice, including, without
limitation, qualifications under applicable blue sky or other state securities
laws (provided that the Corporation shall not be required in connection
therewith to qualify as a foreign corporation or to execute a general consent to
service of process in any state); provided, however, that (i) if in the case of
an underwritten public offering of the Registration Shares the managing
underwriter shall advise the Corporation that the inclusion of some or all of
such Supplemental Registration Shares would, in such managing underwriter's
judgment, materially interfere with the proposed distribution of the
Registration Shares, then the Corporation may, upon written notice to the
Stockholders holding Supplemental Registration Shares, allocate or eliminate (x)
first, shares of Common Stock held by officers or directors of the Corporation
otherwise to be included in the registration statement, and (y) second, the
Supplemental Registration Shares otherwise to be included in the registration
statement (if and to the extent such allocation or elimination is indicated by
such managing underwriter as necessary to eliminate such interference after
giving effect to clause (x) above) pro rata among the holders of the
Supplemental Registration Shares on the basis of the number of Supplemental
Registration Shares held by the holders thereof, (ii) if the legend set forth in
Section 2(a) is or has been removed from the certificates evidencing any of the
Supplemental Registration Shares pursuant to Section 2(b), then the Corporation
shall not be required to take any action with respect to the registration of
such Supplemental Registration Shares or other steps contemplated hereby in
connection therewith and (iii) the Corporation shall have the right to delay or
abandon such registration at any time in the event that the Board of Directors
of the Corporation determines in good faith that such delay is in the best
interest of the Corporation.
 
                                      D-2
<PAGE>
    (f) If and whenever the Corporation is required by the provisions of this
Section 1 to use its reasonable best efforts to effect the registration under
the Securities Act of any securities requested to be so registered by any
Stockholder, the Corporation will, as promptly as practicable:
 
        (i) prepare and file with the Securities and Exchange Commission (the
    "Commission") a registration statement with respect to such securities and
    use its reasonable best efforts to cause such registration statement to
    become effective;
 
        (ii) prepare and file with the Commission such amendments and
    supplements to such registration statement and the prospectus used in
    connection therewith as may be necessary to keep such registration statement
    effective for a period from the date of the effectiveness thereof through
    the earlier of (1) the date which is nine (9) months after the date of
    effectiveness thereof and (2) the date on which all Demand Registration
    Shares and/or Supplemental Registration Shares included in such registration
    statement shall have been sold or otherwise disposed of by Stockholders
    pursuant to such registration statement, and to comply with the provisions
    of the Securities Act with respect to the sale or other disposition of all
    shares of Common Stock covered by such registration statement whenever such
    Stockholder(s), shall desire to sell or otherwise dispose of the same within
    such period;
 
       (iii) furnish to such Stockholder(s), as applicable, such number of
    copies of a prospectus, including a preliminary prospectus and final
    prospectus, in conformity with the requirements of the Securities Act, and
    such other documents as may reasonably be requested thereby in order to
    facilitate the public sale or other disposition of such shares of Common
    Stock owned thereby;
 
        (iv) notify the Stockholder Representative promptly of any request by
    the Commission for the amendment or supplement of such registration
    statement or prospectus or for additional information, and notify such
    stockholder promptly of the filing of each amendment or supplement to such
    registration statement or prospectus;
 
        (v) advise the Stockholder Representative, promptly after it shall
    receive notice, of the issuance of any stop order by the Commission
    suspending the effectiveness of such registration statement or the
    initiation or threatening of any proceeding for that purpose and promptly
    use its reasonable best efforts to prevent the issuance of any stop order or
    to obtain its withdrawal if such stop order should be issued;
 
        (vi) with respect to any registration statement relating to an
    underwritten offering which includes Demand Registration Shares and/or
    Supplemental Registration Shares, upon the request of the Stockholder
    Representative, the Corporation shall cooperate with the Stockholder
    Representative to obtain and furnish at the closing provided for in the
    underwriting agreement (1) an opinion of counsel to the Corporation, dated
    such date, addressed to the underwriters and to the Stockholder(s)
    registering the sale of shares of Common Stock, and (2) a "cold comfort"
    letter from the independent certified public accountants of the Corporation,
    dated such date, addressed to the underwriters and to such Stockholder(s),
    in each case, covering substantially the same matters with respect to the
    issuer, such registration statement (and the prospectus included therein)
    and with respect to the events subsequent to the date of the financial
    statements included in such registration statement, as are customarily
    covered in opinions of issuer's counsel and in accountants' letters
    delivered to the underwriters in underwritten public offerings of
    securities;
 
       (vii) notify such Stockholder(s), in writing, at any time when a
    prospectus relating to such shares of Common Stock is required to be
    delivered under the Securities Act within the appropriate period mentioned
    in clause (ii) immediately preceding, of the happening of any event as a
    result of which the prospectus included in such registration statement, as
    then in effect, includes an untrue statement of a material fact or omits to
    state a material fact required to be stated therein or necessary to make the
    statements therein not misleading in the light of the circumstances then
    existing, and promptly prepare (and file with the Commission) and furnish to
    the Stockholder(s) whose shares of Common Stock are offered in such
    prospectus a reasonable number of copies of a supplement to or an amendment
    of such prospectus as may be necessary so that, as thereafter delivered to
    the purchasers
 
                                      D-3
<PAGE>
    of such shares of Common Stock, such prospectus shall not include an untrue
    statement of a material fact or omit to state a material fact required to be
    stated therein or necessary to make the statements therein not misleading in
    the light of the circumstances then existing.
 
    (g) The Stockholders agree to furnish the Corporation such information
regarding themselves and the proposed distribution of Demand Registration Shares
or Supplemental Registration Shares, as the case may be, by such Stockholder(s)
as the Corporation may from time to time reasonably request in writing in order
to prepare a registration statement and prospectus or any supplement or
amendment thereto pursuant to the Securities Act and the rules and regulations
promulgated thereunder.
 
    (h) The Stockholders agree that, upon receipt of a written notice from the
Corporation of the happening of any event of the kind described in clause (vii)
of Section 1(f) above, they will forthwith discontinue their disposition of
Demand Registration Shares or Supplemental Registration Shares, as the case may
be, pursuant to the registration statement relating to such Demand Registration
Shares or Supplemental Registration Shares, as the case may be, until their
receipt of the copies of the supplemented or amended prospectus contemplated by
clause (vii) of Section 1(f) above and, if so requested by the Corporation in
writing, will deliver to the Corporation (at the Corporation's expense) all
copies then in their possession, other than permanent file copies, of the
prospectus relating to such Demand Registration Shares or Supplemental
Registration Shares, as the case may be.
 
    (i) The Corporation shall pay all expenses (the "Registration Expenses")
necessary to effect under the Securities Act any registration statements,
amendments or supplements filed pursuant to this Section 1 (other than any
underwriters' discounts and commissions and any brokerage commissions and fees
payable with respect to shares of Common Stock sold by any Stockholder and legal
fees and expenses of counsel to the Stockholders other than, in connection with
a registration statement prepared pursuant to Section 1(a) and the first two
registration statements which include Supplemental Registration Shares,
reasonable fees and expenses of one counsel to the Stockholders selected by the
Stockholder Representative), including, without limitation, printing expenses,
fees of the Commission and the National Association of Securities Dealers, Inc.,
expenses of compliance with blue sky and other state securities laws, and
accounting and legal fees and expenses of counsel to the Corporation and, in
connection with a registration statement prepared pursuant to Section 1(a) and
the first two registration statements which include Supplemental Registration
Shares, reasonable fees and expenses of one counsel to the Stockholders selected
by the Stockholder Representative; provided, however, that in the event that the
registration statement is not declared effective as a result of the withdrawal
by one or more Stockholders of the Demand Registration Shares from the
registration (a "Withdrawn Registration"; provided, that a Withdrawn
Registration shall not include a registration statement withdrawn by the
applicable person(s) as a result of a delay imposed by the Corporation pursuant
to Section 1(b)(ii) hereof), such Withdrawn Registration shall count as one of
the two registration statements prepared pursuant to Section 1(a) with respect
to which the Corporation is obligated to pay the Registration Expenses unless
such Stockholder(s) shall pay all Registration Expenses incurred by the
Corporation in the Withdrawn Registration (but in any event such Withdrawn
Registration shall not count as one of the two registration statements that the
Corporation is obligated to file and cause to become effective pursuant to
Section 1(a)). Nothing herein shall be deemed to prohibit the same counsel from
representing both the Corporation and the Stockholders in connection with any
such registration, subject to obtaining required consents.
 
    (j) It is understood and agreed that the Corporation shall not be obligated
to provide or effect an underwritten offering of shares of Common Stock in the
event that a registration is effected pursuant to Section 1(a) hereof. Whenever
a registration statement requested pursuant to Section 1(a) hereof covers an
underwritten public offering (as determined by the Corporation) the Stockholder
Representative shall have, subject to the reasonable prior approval of the
Corporation (including based on recognized standing and pricing factors), the
right to select the managing underwriter(s) to administer the offering. In the
event of an underwritten public offering as aforesaid, the Corporation agrees
reasonably to cooperate (and to cause its officers reasonably to cooperate) with
the managing underwriter(s) in a manner customary for issuers of securities in
an underwritten secondary public offering. If the Corporation at any time
proposes to register any of its securities under the Securities Act for sale for
its own account and such securities are
 
                                      D-4
<PAGE>
to be distributed by or through one or more underwriter(s), the Corporation will
have the right to select the managing underwriter(s) to administer the offering,
provided that if the number of Supplemental Registration Shares is greater than
the number of shares to be sold by the Corporation in connection therewith, the
Corporation shall give due consideration to any reasonable request by the
Stockholder Representative that a particular investment banking firm of
recognized standing be included in the underwriting syndicate.
 
    (k) Each Stockholder agrees that, in the event the Corporation files a
registration statement under the Securities Act with respect to an underwritten
public offering of any securities of the Corporation in which such Stockholder
was permitted to participate (whether or not such Stockholder does in fact
participate), if required by the underwriters thereof, such Stockholder will not
effect any public sale or distribution, including any sale pursuant to Rule 144
promulgated under the Securities Act, of any equity securities of the
Corporation or any securities convertible into or exchangeable or exercisable
for any equity security of the Corporation (other than as part of such
underwritten public offering) during the seven days prior to or 90 days after,
or such longer period as may be required by the underwriters thereof (not to
exceed in any event 180 days), the effectiveness of such registration statement.
 
    (l) The Corporation agrees that, in the event the Corporation files a
registration statement under the Securities Act with respect to an underwritten
public offering of any Demand Registration Shares, if required by the
underwriters thereof, the Corporation will not effect any public sale or
distribution of any equity securities of the Corporation or any securities
convertible into or exchangeable or exercisable for any equity security of the
Corporation (other than as part of such underwritten public offering) during the
seven days prior to or 90 days after, or such longer period as may be required
by the underwriters thereof (not to exceed in any event 180 days), the
effectiveness of such registration statement, other than (i) pursuant to
employee stock option plans in existence on the effective date of the
registration statement, (ii) upon the conversion of convertible securities or
the exercise of warrants outstanding on such effective date, or (iii) in
connection with an acquisition by the Corporation, whether in the form of an
asset purchase, stock exchange, merger or otherwise.
 
    (m) In the event of any registration pursuant to this Section 1 covering
shares of Common Stock beneficially owned by any Stockholder, the Corporation
will indemnify and hold harmless each such Stockholder (if shares of Common
Stock of that person are included in the subject registration statement), each
such Stockholder's directors, officers and general partners, if any, the
directors and officers of any such general partner, each underwriter (as defined
in the Securities Act), if any, of Demand Registration Shares and each other
person or entity, if any, who controls such Stockholder or underwriter within
the meaning of the Securities Act (collectively, the "Indemnitees") against any
losses, claims, damages, costs, expenses (including reasonable attorneys' fees),
or liabilities (or actions in respect thereof) to which such Stockholder or
controlling person or entity becomes subject, under the Securities Act or
otherwise, insofar as such losses, claims, damages, costs, expenses or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
the related registration statement, any preliminary prospectus or final
prospectus contained therein, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances in which they were made;
provided, however, that the Corporation will not be liable in any such case to
an Indemnitee to the extent that any such loss, claim, damage, cost, expense or
liability arises out of or is based upon (x) an untrue statement or alleged
untrue statement or omission or alleged omission made in such registration
statement, preliminary prospectus, prospectus or amendment or supplement in
reliance upon and in conformity with written information furnished by any
Indemnitee, specifically for use in the preparation thereof or (y) such
Indemnitee's failure to deliver a copy of the prospectus or any amendments or
supplements thereto (if required by applicable law) to the person asserting any
loss, claim, damage or liability after the Corporation has furnished such
Indemnitee with the same and the loss, claim, damage or liability of such
Indemnitee results from an untrue statement or omission of a material fact which
was corrected therein. The Corporation also agrees to reimburse each
 
                                      D-5
<PAGE>
Indemnitee for any legal or other expenses reasonably incurred by such
Indemnitee in connection with investigating or defending any such loss, claim,
damage, liability or action.
 
    (n) In the event of any registration pursuant to this Section 1 covering
shares of Common Stock beneficially owned by any Stockholder, each such
Stockholder (if shares of Common Stock of that person are included in the
subject registration statement) shall severally (and not jointly) indemnify and
hold harmless the Corporation, each of its directors and officers, and each
other person or entity, if any, who controls the Corporation within the meaning
of the Securities Act, against any losses, claims, damages, costs, expenses
(including reasonable attorneys' fees) or liabilities (or actions in respect
thereof) to which the Corporation or any such director, officer, or controlling
person becomes subject, under the Securities Act or otherwise, insofar as such
losses, claims, damages, costs, expenses or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue or alleged untrue statement
of any material fact contained in the related registration statement, and any
preliminary prospectus or final prospectus contained therein, or any amendment
or supplement thereto, or arise out of or are based upon the omission or the
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading in light of the
circumstances in which they were made, in each case to the extent, but only to
the extent, that such loss, claim, damage, cost, expense or liability arises out
of or is based upon (x) an untrue statement or alleged untrue statement or
omission or alleged omission made in such registration statement, preliminary
prospectus, prospectus, amendment or supplement in reliance upon and in
conformity with written information furnished by such Stockholder specifically
for use in the preparation thereof or (y) such Stockholder's failure to deliver
a copy of the prospectus or any amendments or supplements thereto (if required
by applicable law) to the person asserting any loss, claim, damage or liability
after the Corporation has furnished such Stockholder with the same and the loss,
claim, damage or liability of such Indemnitee results from an untrue statement
or omission of a material fact which was corrected therein. Each such
Stockholder shall severally (and not jointly) reimburse any legal or other
expenses reasonably incurred by the Corporation or any such director, officer,
or controlling person or entity in connection with investigating or defending
any such loss, claim, damage, liability or action.
 
    (o) Promptly after receipt by an indemnified party under this Section 1 of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against any indemnifying party under this
Section 1, notify the indemnifying party of the commencement thereof; provided,
however, that failure to so notify the indemnifying party shall not affect an
indemnifying party's obligations hereunder, except to the extent that the
indemnifying party is materially prejudiced by such failure. The indemnifying
party shall be entitled to appoint counsel of the indemnifying party's choice at
the indemnifying party's expense to represent the indemnified party in any
action for which indemnification is sought (in which case the indemnifying party
shall not thereafter be responsible for the fees and expenses of any separate
counsel retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be reasonably satisfactory to the
indemnified party. Notwithstanding the indemnifying party's election to appoint
counsel to represent the indemnified party in an action, the indemnified party
shall have the right to employ separate counsel (including local counsel), and
the indemnifying party shall bear the reasonable fees, costs and expenses of
such separate counsel if (i) the use of counsel chosen by the indemnifying party
to represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel reasonably satisfactory to
the indemnified party to represent the indemnified party within a reasonable
time after notice of the institution of such action or (iv) the indemnifying
party shall authorize the indemnified party to employ separate counsel at the
expense of the indemnifying party. It is understood, however, that the
indemnifying party shall, in connection with any one such action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable for the reasonable fees
and expenses of only one separate firm of attorneys (in addition to any local
counsel) at any time.
 
                                      D-6
<PAGE>
    (p) No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened action,
suit or proceeding in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party, unless such settlement includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter of
such action, suit or proceeding.
 
    (q) If the indemnification provided for in this Section 1 is applicable in
accordance with its terms but for any reason is held to be unavailable to or
insufficient to hold harmless an indemnified party under paragraphs (m) or (n)
of this Section 1 in respect of any losses, claims, damages, costs, expenses or
liabilities referred to therein, then each applicable indemnifying party, in
lieu of indemnifying such indemnified party, shall contribute to the amount paid
or payable (including any investigative, legal and other expenses reasonably
incurred in connection with, and any amount paid in settlement of, any action,
suit or proceeding or any claim asserted, but after deducting any contribution
received by the indemnifying party from persons other than the indemnified
parties, such as persons who control the indemnifying party within the meaning
of the Securities Act, officers of the Corporation who signed the registration
statement and directors of the Corporation, who also may be liable for
contribution) by such indemnified party as a result of such losses, claims,
liabilities, expenses and damages in such proportion as shall be appropriate to
reflect the relative benefits received by the indemnifying party, on the one
hand, and the indemnified parties, on the other hand. The relative benefits
received by the indemnifying party, on the one hand, and the indemnified
parties, on the other hand, shall be deemed to be in the same proportion as the
total net proceeds from the offering registered pursuant to the registration
statement (after deducting expenses) received by the indemnifying party bear to
the total net proceeds from the offering (after deducting expenses) received by
the indemnified parties, in each case as set forth in the table on the cover
page of the prospectus. If, but only if, the allocation provided by the
foregoing sentence is not permitted by applicable law, the allocation of
contribution shall be made in such proportion as is appropriate to reflect not
only the relative benefits referred to in the foregoing sentence but also the
relative fault of the indemnifying party, on the one hand, and the indemnified
parties, on the other hand, with respect to the statements or omissions which
resulted in such loss, claim, liability, expense or damage, or action in respect
thereof, as well as any other relevant equitable considerations with respect to
such offering. Such relative fault shall be determined by reference to whether
the untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information supplied by the
indemnifying party, the intent of the parties and their relative knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Corporation and the Stockholders agree that it would not be just
and equitable if contributions pursuant to this Section 1(q) were to be
determined by pro rata allocation or by any other method of allocation which
does not take into account the equitable considerations referred to herein. The
amount paid or payable by an indemnified party as a result of the loss, claim,
liability, expense or damage, or action in respect thereof, referred to above in
this Section 1(q) shall be deemed to include, for purposes of this Section 1(q),
any legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 1(q), no person found guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) will be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Stockholders' obligations to
contribute as provided in this Section 1(q) are several in proportion to their
respective Demand Registration Shares and/or Supplemental Registration Shares
included in the registration statement, and not joint. For purposes of this
Section 1(q), any person who controls a party to this Agreement within the
meaning of the Securities Act will have the same rights to contribution as that
party, and each officer and director of the Corporation who signed the
registration statement will have the same rights to contribution as the
Corporation, subject in each case to the provisions hereof. Any party entitled
to contribution, promptly after receipt of notice of commencement of any action
against any such party in respect of which a claim for contribution may be made
under this Section 1(q), will notify any such party or parties from whom
contribution may be sought, but the omission so to notify will not relieve the
party or parties from whom contribution may be sought from any other obligation
it or they may have under this Section 1(q). No party will be liable for
 
                                      D-7
<PAGE>
contribution with respect to any action or claim settled without its written
consent (which consent will not be unreasonably withheld).
 
    (r) With respect to any underwritten offering, each Stockholder (if shares
of Common Stock of that person are included in the subject registration
statement) and the Corporation shall, in addition to the foregoing, provide the
underwriters of such offering with customary representations and warranties, and
indemnification, in each instance as shall be reasonably requested by the
underwriters thereof, provided, however, that (i) any such agreement to
indemnify an underwriter with respect to any preliminary prospectus shall not
inure to the benefit of any such underwriter to the extent that any loss, claim,
damage, cost, expense or liability of any such underwriter results solely from
an untrue statement of material fact contained in, or the omission of a material
fact from, such preliminary prospectus which untrue statement or omission was
corrected in the final prospectus, if such underwriter failed to send or give a
copy of the final prospectus to the person asserting such loss, claim, damage,
cost, expense or liability at or prior to the written confirmation of the sale
of such securities to such person, and (ii) no Stockholder will be liable to the
extent that such loss, claim, liability, expense or damage is based on an untrue
statement or omission or alleged untrue statement or omission made in reliance
on and in conformity with information relating to any underwriter furnished in
writing to the Corporation by or on behalf of any underwriter, expressly for
inclusion in the registration statement, a preliminary prospectus or the
prospectus, and provided further that any such agreement by any Stockholder to
indemnify an underwriter shall be on a several (and not joint) basis in
proportion to the number of securities sold by such Stockholder in such
underwritten offering and shall be limited in amount to the net proceeds
received by such Stockholder in such underwritten offering.
 
    2.  LEGEND AND COMPLIANCE WITH SECURITIES LAWS.  (a) The stock certificates
evidencing the shares of Common Stock of the Stockholders subject to this
Agreement shall bear a legend reading substantially as follows:
 
        "These securities have not been registered under the Securities Act
    of 1933, as amended, or qualified under state securities laws and may
    not be sold, pledged or otherwise transferred unless (a) covered by an
    effective registration statement under the Securities Act of 1933, as
    amended, and qualified under applicable state securities laws, or (b)
    the Corporation shall have been furnished with an opinion of counsel
    reasonably acceptable to the Corporation to the effect that no
    registration or qualification is legally required for such transfer."
 
    (b) In the event that a registration statement covering the shares of Common
Stock of the Corporation owned by the Stockholders which are subject to this
Agreement shall become effective under the Securities Act and under any
applicable state securities laws or in the event that the Corporation shall
receive an opinion of counsel to the holder of such shares of Common Stock or
counsel to the Corporation in form and substance reasonably satisfactory to the
Corporation that, in the opinion of such counsel, the above stated legend is
not, or is no longer, necessary or required under applicable law (including,
without limitation, because of the availability of the exemption afforded by
Rule 144(k) promulgated under the Securities Act), the Corporation shall, or
shall instruct its transfer agents and registrars to, remove the above stated
legend from the stock certificates evidencing such shares of Common Stock or
issue new certificates without such legend in lieu thereof.
 
    (c) Each Stockholder consents to the Corporation making a notation on its
records and giving instructions to any transfer agent for the Common Stock in
order to implement the restrictions on transfer established in this Section 2.
 
    3.  APPOINTMENT OF STOCKHOLDER REPRESENTATIVE.
 
    (a) Each Stockholder hereby makes, constitutes and appoints Genstar to be
such Stockholder's true and lawful attorney in fact and agent (the "Stockholder
Representative"), for such Stockholder and in such Stockholder's name, as
effectively as such Stockholder could act for himself, herself or itself, with
full power of substitution in the premises, to take all actions which under this
Agreement are to be or may be taken by such Stockholder, including, without
limitation, to give and receive all consents, waivers,
 
                                      D-8
<PAGE>
amendments, notices and other communications to be given or which may be given
or received or may be received under this Agreement. The death or incapacity of
any Stockholder shall not terminate the agency and power of attorney granted
hereby to the Stockholder Representative. Such agency and power of attorney is
irrevocable and coupled with an interest, and the provisions of this Section 3
are independent and severable and shall be enforceable notwithstanding any
rights or remedies that any Stockholder may have in connection with, or in any
way arising out of, the transactions contemplated by this Agreement. The
obligations hereunder of Genstar, as representative, shall not be terminated by
operation of law, whether by its liquidation, dissolution or by the occurrence
of any other event. In the event Genstar should liquidate or dissolve, or for
any other reason become unable to perform its responsibilities hereunder, or
resign such position, the Stockholders holding a majority of the shares of
Common Stock held by all Stockholders shall select another representative by
written notice executed by such Stockholders and delivered to the Corporation to
fill such vacancy and such substituted representative shall be deemed the
Stockholder Representative for all purposes of this Agreement.
 
    (b) The Corporation shall be entitled to rely conclusively on the actions,
communications, instructions, decisions and agreements of the Stockholder
Representative as being the actions, communications, instructions, decisions and
agreements of each of the Stockholders (without the need to communicate or
otherwise confirm such with any Stockholder), and no Stockholder shall have any
claim or cause of action against the Corporation for any action taken or not
taken by the Corporation in reliance upon the actions, communications,
instructions, decisions or agreements of the Stockholder Representative.
 
    (c) All actions, communications, instructions, decisions and agreements of
the Stockholder Representative shall be conclusive and binding upon all of the
Stockholders and no Stockholder shall have any claim or cause of action against
the Stockholder Representative for any action taken or not taken by the
Stockholder Representative in its role as such, except for any action or
omission taken or made fraudulently or in bad faith with respect to such
Stockholder.
 
    4.  INVESTMENT IN THE CORPORATION.
 
    (a) Each of the Stockholders understands that the Corporation proposes to
issue and deliver to the Stockholders the shares of Common Stock pursuant to the
Merger Agreement without compliance with the registration requirements of the
Securities Act; and that for such purpose the Corporation will rely upon the
Stockholders' representations and warranties contained herein.
 
    (b) Each of the Stockholders understands that, under the existing rules of
the Commission, the Stockholders may be unable to sell their shares of Common
Stock except to the extent that such shares may be sold, (i) pursuant to an
effective registration statement covering such sale pursuant to the Securities
Act and applicable state securities laws or an applicable exemption therefrom or
(ii) in a bona fide private placement to a purchaser who shall be subject to the
same restrictions on any resale or (iii) subject to the restrictions contained
in Rule 144.
 
    (c) None of the Stockholders is relying on the Corporation respecting the
financial, tax and other economic considerations of an investment in the Common
Stock, and each of the Stockholders has relied on the advice of, or has
consulted with, only its own advisors.
 
    (d) Each of the Stockholders is familiar with the provisions of Rule 144 and
the limitations upon the availability and applicability of such rule.
 
    (e) Each of the Stockholders is a sophisticated investor familiar with the
type of risks inherent in the acquisition of restricted securities such as the
shares of Common Stock to be issued to it and its financial position is such
that it can afford to retain such shares for an indefinite period of time
without realizing any direct or indirect cash return on its investment.
 
    (f) Each of the Stockholders has such knowledge and experience in financial,
tax and business matters so as to evaluate the merits and risks of an investment
in the Common Stock and to make an informed investment decision with respect
thereto.
 
                                      D-9
<PAGE>
    (g) Each of the Stockholders is acquiring its shares of Common Stock as an
investment for its sole account, and without any present view towards the resale
or other distribution thereof.
 
    5.  REORGANIZATION, ETC.  The provisions of this Agreement shall apply
mutatis mutandi to any shares of capital stock resulting from any stock split or
reverse split, stock dividend, reclassification of the capital stock of the
Corporation, consolidation, merger or reorganization of the Corporation.
 
    6.  NOTICES.  Any notice or other communication under this Agreement shall

Unless otherwise expressly provided in the Plan, all designations,

made at any time and shall be final, conclusive and binding upon all Persons,
including the Company, any Affiliate, any Participant, any holder or beneficiary
of any Award, any shareholder and any Employee. Notwithstanding the foregoing,
the maximum number of Awards which may be granted to any one Participant under
this Plan in any two-year period shall not exceed 100,000 Common Shares, subject
to the adjustments provided in Section 4(b) hereof and no Awards under this Plan
shall be granted after June 30, 2006.
 
    SECTION 4.  COMMON SHARES AVAILABLE FOR AWARDS.
 
    (a)  COMMON SHARES AVAILABLE.  Subject to adjustment as provided in Section
4(b):
 
        (i)  CALCULATION OF NUMBER OF COMMON SHARES AVAILABLE.  The number of
    Common Shares available for granting Awards under the Plan shall be 750,000,
    any or all of which may be or may be based on Common Stock, any other
    security which becomes the subject of Awards, or any combination thereof.
    Initially, 750,000 shares of Common Stock shall be reserved for Awards
    hereunder. Further, if, after the effective date of the Plan, any Common
    Shares covered by an Award granted under the Plan or to which such an Award
    relates, are forfeited, or if an Award otherwise terminates or is canceled
    without the delivery of Shares or of other consideration, then the Common
    Shares covered by such Award or to which such Award relates, or the number
    of Common Shares otherwise counted against the aggregate number of Common
    Shares available under the Plan with respect to such Award, to the extent of
    any such forfeiture, termination or cancellation, shall again be, or shall
    become, available for granting Awards under the Plan.
 
        (ii)  ACCOUNTING FOR AWARDS.  For purposes of this Section 4,
 
           (A) if an Award is denominated in or based upon Common Shares, the
       number of Common Shares covered by such Award or to which such Award
       relates shall be counted on the date of grant of such Award against the
       aggregate number of Common Shares available for granting Awards under the
       Plan and against the maximum number of Awards available to any
       Participant; and
 
           (B) Awards not denominated in Common Shares may be counted against
       the aggregate number of Common Shares available for granting Awards under
       the Plan and against the maximum number of Awards available to any
       participant in such amount and at such time as the Committee shall
       determine under procedures adopted by the Committee consistent with the
       purposes of the Plan;
 
                                      E-3
<PAGE>
    PROVIDED, HOWEVER, that Awards that operate in tandem with (whether granted
    simultaneously with or at a different time from), or that are substituted
    for, other Awards may be counted or not counted under procedures adopted by
    the Committee in order to avoid double counting. Any Common Shares that are
    delivered by the Company, and any Awards that are granted by, or become
    obligations of, the Company, through the assumption by the Company or an
    Affiliate of, or in substitution for, outstanding awards previously granted
    by an acquired company shall, in the case of Awards granted to Participants
    who are officers or directors of the Company for purposes of Section 16 of
    the Exchange Act, be counted against the Common Shares available for
    granting Awards under the Plan.
 
       (iii)  SOURCES OF COMMON SHARES DELIVERABLE UNDER AWARDS.  Any Common
    Shares delivered pursuant to an Award may consist, in whole or in part, of
    authorized and unissued Common Shares or of treasury Common Shares.
 
    (b)  ADJUSTMENTS.  In the event that the Committee shall determine that any
dividend or other distribution (whether in the form of cash, Common Shares,
other securities or other property), recapitalization, stock split, reverse
stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase or exchange of Common Shares or other securities of the
Company, issuance of warrants or other rights to purchase Common Shares or other
securities of the Company, or other similar corporate transaction or event
affects the Common Shares such that an adjustment is determined by the Committee
to be appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Plan, then the
Committee shall, in such manner as it may deem equitable, adjust any or all of
(i) the number and kind of Common Shares (or other securities or property) which
thereafter may be made the subject of Awards, (ii) the number and kind of Common
Shares (or other securities or property) subject to outstanding Awards, and
(iii) the grant or exercise price with respect to any Award or, if deemed
appropriate, make provision for a cash payment to the holder of an outstanding
Award; PROVIDED, HOWEVER, that the number of Common Shares subject to any Award
denominated in Common Shares shall always be a whole number.
 
    In connection with any merger or consolidation in which the Company is not
the surviving corporation and which results in the holders of the outstanding
voting securities of the Company (determined immediately prior to such merger or
consolidation) owning less than a majority of the outstanding voting securities
of the surviving corporation (determined immediately following such merger or
consolidation), or any sale or transfer by the Company of all or substantially
all its assets or any tender offer or exchange offer for or the acquisition,
directly or indirectly, by any person or group of all or a majority of the then
outstanding voting securities of the Company, all outstanding Options under the
Plan shall become exercisable in full, notwithstanding any other provision of
the Plan or of any outstanding Options granted thereunder, on and after (i) the
fifteenth day prior to the effective date of such merger, consolidation, sale,
transfer or acquisition or (ii) the date of commencement of such tender offer or
exchange offer, as the case may be. The provisions of the foregoing sentence
shall apply to any outstanding Options which are Incentive Stock Options to the
extent permitted by Section 422(d) of the Code and such outstanding Options in
excess thereof shall, immediately upon the occurrence of the event described in
clause (i) or (ii) of the foregoing sentence, be treated for all purposes of the
Plan as Non-Qualified Stock Options and shall be immediately exercisable as such
as provided in the foregoing sentence.
 
    SECTION 5.  ELIGIBILITY.  Any Employee, including any officer or
employee-director of the Company or of any Affiliate, and any consultant of, or
other individual providing services to, the Company or any Affiliate shall be
eligible to be designated a Participant. A non-employee director shall be
eligible to receive Non-Qualified Stock Options under the Plan.
 
    SECTION 6.  AWARDS.
 
    (a)  OPTIONS.  The Committee is hereby authorized to grant to eligible
individuals options to purchase Common Shares (each, an "Option") which shall
contain the following terms and conditions and
 
                                      E-4
<PAGE>
with such additional terms and conditions, in either case not inconsistent with
the provisions of the Plan, as the Committee shall determine:
 
        (i)  EXERCISE PRICE.  The purchase price per Common Share purchasable
    under an Option shall be determined by the Committee; PROVIDED, HOWEVER,
    that such purchase price shall not be less than one hundred percent (100%)
    of the Fair Market Value of a Common Share on the date of grant of such
    Option, or such other price as required under Subsection 6(a)(iv) hereof.
 
        (ii)  TIME AND METHOD OF EXERCISE.  Subject to the terms of Section
    6(a)(iii), the Committee shall determine the time or times at which an
    Option may be exercised in whole or in part, and the method or methods by
    which, and the form or forms (including, without limitation, cash, Common
    Shares, outstanding Awards, or other property, or any combination thereof,
    having a Fair Market Value on the exercise date equal to the relevant
    exercise price) in which, payment of the exercise price with respect thereto
    may be made or deemed to have been made.
 
        (iii)  EXERCISABILITY UPON DEATH, RETIREMENT AND TERMINATION OF
    EMPLOYMENT.  Subject to the condition that no Option may be exercised in
    whole or in part after the expiration of the Option period specified in the
    applicable Award Agreement:
 
           (A) Subject to the terms of paragraph (D) below, upon the death of a
       Participant while employed or within 3 months of retirement or disability
       as defined in paragraph (B) below, the Person or Persons to whom such
       Participant's rights with respect to any Option held by such Participant
       are transferred by will or the laws of descent and distribution may,
       prior to the expiration of the earlier of: (1) the outside exercise date
       determined by the Committee at the time of granting the Option, or (2)
       nine months after such Participant's death, purchase any or all of the
       Common Shares with respect to which such Participant was entitled to
       exercise such Option immediately prior to such Participant's death, and
       any Options not so exercisable will lapse on the date of such
       Participant's death;
 
           (B) Subject to the terms of paragraph (D) below, upon termination of
       a Participant's employment with the Company (x) as a result of retirement
       pursuant to a retirement plan of the Company or an Affiliate or
       disability (as determined by the Committee) of such Participant, (y) by
       the Company other than for Cause, or (z) by the Participant with Good
       Reason, such Participant may, prior to the expiration of the earlier of:
       (1) the outside exercise date determined by the Committee at the time of
       granting the Option, or (2) three months after the date of such
       termination, purchase any or all of the Common Shares with respect to
       which such Participant was entitled to exercise any Options immediately
       prior to such termination, and any Options not so exercisable will lapse
       on such date of termination;
 
           (C) Subject to the terms of paragraph (D) below, upon termination of
       a Participant's employment with the Company under any circumstances not
       described in paragraphs (A) or (B) above, such Participant's Options
       shall be canceled to the extent not theretofore exercised;
 
           (D) Upon (i) the death of the Participant, or (ii) termination of the
       Participant's employment with the Company (x) by the Company other than
       for Cause (y) by the Participant with Good Reason or (z) as a result of
       retirement or disability as defined in paragraph (B) above, the Company
       shall have the right to cancel all of the Options such Participant was
       entitled to exercise at the time of such death or termination (subject to
       the terms of paragraphs (A) or (B) above) for a payment in cash equal to
       the excess, if any, of the Fair Market Value of one Common Share on the
       date of death or termination over the exercise price of such Option for
       one Common Share times the number of Common Shares subject to the Option
       and exercisable at the time of such death or termination; and
 
           (E) Upon expiration of the respective periods set forth in each of
       paragraphs (A) through (C) above, the Options of a Participant who has
       died or whose employment has been terminated shall be canceled to the
       extent not theretofore canceled or exercised.
 
                                      E-5
<PAGE>
           (F) For purposes of paragraphs (A) through (D) above, the period of
       service of an individual as a director or consultant of the Company or an
       Affiliate shall be deemed the period of employment.
 
        (iv)  INCENTIVE STOCK OPTIONS.  The following provisions shall apply
    only to Incentive Stock Options granted under the Plan:
 
           (A) No Incentive Stock Option shall be granted to any eligible
       Employee who, at the time such Option is granted, owns securities
       possessing more than ten percent (10%) of the total combined voting power
       of all classes of securities of the Company or of any Affiliate, except
       that such an Option may be granted to such an Employee if at the time the
       Option is granted the option price is at least one hundred ten percent
       (110%) of the Fair Market Value of the Common Shares (determined in
       accordance with Section 2) subject to the Option, and the Option by its
       terms is not exercisable after the expiration of five (5) years from the
       date the Option is granted; and
 
           (B) To the extent that the aggregate Fair Market Value of the Common
       Shares with respect to which Incentive Stock Options (without regard to
       this subsection) are exercisable for the first time by any individual
       during any calendar year (under all plans of the Company and its
       Affiliates) exceeds $100,000, such Options shall be treated as
       Non-Qualified Stock Options. This subsection shall be applied by taking
       Options into account in the order in which they were granted. If some but
       not all Options granted on any one day are subject to this subsection,
       then such Options shall be apportioned between Incentive Stock Option and
       Non-Qualified Stock Option treatment in such manner as the Committee
       shall determine. For purposes of this subsection, the Fair Market Value
       of any Common Shares shall be determined, in accordance with Section 2,
       as of the date the Option with respect to such Common Shares is granted.
 
        (v)  TERMS AND CONDITIONS OF OPTIONS GRANTED TO
    DIRECTORS.  Notwithstanding any provision contained in the Plan to the
    contrary, during any period when any member of the Committee shall not be a
    "disinterested person" as defined in Rule 16b-3, as such Rule was in effect
    at April 30, 1991, then, the terms and conditions of Options granted under
    the Plan to any director of the Company during such period shall be as
    follows:
 
           (A) The price at which each Common Share subject to an option may be
       purchased shall, subject to any adjustments which may be made pursuant to
       Section 4, in no event be less than the Fair Market Value of a Common
       Share on the date of grant, and provided further that in the event the
       option is intended to be an Incentive Stock Option and the optionee owns
       on the date of grant securities possessing more than ten percent (10%) of
       the total combined voting power of all classes of securities of the
       Company or of any Affiliate, the price per share shall not be less than
       one hundred ten percent (110%) of the Fair Market Value per Common Share
       on the date of grant.
 
           (B) The Option may be exercised to purchase Common Shares covered by
       the Option not sooner than six (6) months following the date of grant.
       The Option shall terminate and no Common Shares may be purchased
       thereunder more than ten (10) years after the date of grant, provided
       that if the Option is intended to be an Incentive Stock Option and the
       Optionee owns on the date of grant securities possessing more than ten
       percent (10%) of the total combined voting power of all classes of
       securities of the Company or of any Affiliate, the Option shall terminate
       and no Common Shares may be purchased thereunder more than five (5) years
       after the date of grant.
 
           (C) The maximum number of Common Shares which may be subject to
       options granted to all directors pursuant to this Section 6(a)(v) shall
       be 300,000 shares in the aggregate. The maximum number of Common Shares
       which may be subject to options granted in any two-year period to any
       director of the Company who is an Employee shall be 100,000 shares and
       the
 
                                      E-6
<PAGE>
       maximum number of Common Shares which may be subject to options granted
       in any two-year period to any director of the Company who is not an
       Employee shall be 10,000 shares.
 
    (b)  STOCK APPRECIATION RIGHTS.  The Committee is hereby authorized to grant
to eligible Employees "Stock Appreciation Rights." Each Stock Appreciation Right
shall consist of a right to receive the excess of (i) the Fair Market Value of
one Common Share on the date of exercise or, if the Committee shall so determine
in the case of any such right other than one related to any Incentive Stock
Option, at any time during a specified period before or after the date of
exercise over (ii) the grant price of the right as specified by the Committee,
which shall not be less than one hundred percent (100%) of the Fair Market Value
of one Common Share on the date of grant of the Stock Appreciation Right (or, if
the Committee so determines, in the case of any Stock Appreciation Right
retroactively granted in tandem with or in substitution for another Award, on
the date of grant of such other Award). Subject to the terms of the Plan and any
applicable Award Agreement, the grant price, term, methods of exercise, methods
of settlement, and any other terms and conditions of any Stock Appreciation
Right granted under the Plan shall be as determined by the Committee. The
Committee may impose such conditions or restrictions on the exercise of any
Stock Appreciation Right as it may deem appropriate.
 
    (c)  RESTRICTED SECURITIES.
 
        (i)  ISSUANCE.  The Committee is hereby authorized to grant to eligible
    Employees "Restricted Securities" which shall consist of the right to
    receive, by purchase or otherwise, Common Shares which are subject to such
    restrictions as the Committee may impose (including, without limitation, any
    limitation on the right to vote such Common Shares or the right to receive
    any dividend or other right or property), which restrictions may lapse
    separately or in combination at such time or times, in such installments or
    otherwise, as the Committee may deem appropriate.
 
        (ii)  REGISTRATION.  Restricted Securities granted under the Plan may be
    evidenced in such manner as the Committee may deem appropriate, including,
    without limitation, book-entry registration or issuance of a stock
    certificates or certificates. In the event any stock certificate is issued
    in respect of Restricted Securities granted under the Plan, such certificate
    shall be registered in the name of the Participant and shall bear an
    appropriate legend referring to the terms, conditions and restrictions
    applicable to such Restricted Securities.
 
        (iii)  FORFEITURE.  Except as otherwise determined by the Committee,
    upon termination of a Participant's employment for any reason during the
    applicable restriction period, all of such Participant's Restricted
    Securities which had not become Released Securities by the date of
    termination of employment shall be forfeited and reacquired by the Company;
    PROVIDED, HOWEVER, that the Committee may, when it finds that a waiver would
    be in the best interests of the Company, waive in whole or in part any or
    all remaining restrictions with respect to such Participant's Restricted
    Securities. Unrestricted Common Shares, evidenced in such manner as the
    Committee shall deem appropriate, shall be issued to the holder of
    Restricted Securities promptly after such Restricted Securities become
    Released Securities.
 
    (d)  PERFORMANCE AWARDS.  The Committee is hereby authorized to grant to
eligible Employees "Performance Awards." Each Performance Award shall consist of
a right, (i) denominated or payable in cash, Common Shares, other securities or
other property (including, without limitation, Restricted Securities), and (ii)
which shall confer on the holder thereof rights valued as determined by the
Committee and payable to, or exercisable by, the holder of the Performance
Award, in whole or in part, upon the achievement of such performance goals
during such performance periods as the Committee shall establish. Subject to the
terms of the Plan and any applicable Award Agreement, the performance goals to
be achieved during any performance period, the length of any performance period,
the amount of any Performance Award granted, the termination of a Participant's
employment and the amount of any payment or transfer to be made pursuant to any
Performance Award shall be determined by the Committee and by the other terms
and conditions of any Performance Award. The Committee shall issue performance
goals prior to the commencement of the performance period to which such
performance goals pertain.
 
                                      E-7
<PAGE>
    (e)  OTHER STOCK-BASED AWARDS.  The Committee is hereby authorized to grant
to eligible Employees "Other Stock-Based Awards." Each Other Stock-Based Award
shall consist of a right (i) which is other than an Award or right described in
Section 6(a), (b), (c) or (d) above and (ii) which is denominated or payable in,
valued in whole or in part by reference to, or otherwise based on or related to,
Common Shares (including, without limitation, securities convertible into Common
Shares) as are deemed by the Committee to be consistent with the purposes of the
Plan; PROVIDED, HOWEVER, that such right shall comply, to the extent deemed
desirable by the Committee, with Rule 16b-3 and applicable law. Subject to the
terms of the Plan and any applicable Award Agreement, the Committee shall
determine the terms and conditions of Other Stock-Based Awards. Common Shares or
other securities delivered pursuant to a purchase right granted under this
Section 6(e) shall be purchased for such consideration, which may be paid by
such method or methods and in such form or forms, including, without limitation,
cash, Common Shares, other securities, other Awards, other property, or any
combination thereof, as the Committee shall determine.
 
    (f)  GENERAL.
 
        (i)  NO CASH CONSIDERATION FOR AWARDS.  Awards may be granted for no
    cash consideration or for such minimal cash consideration as may be required
    by applicable law.
 
        (ii)  AWARDS MAY BE GRANTED SEPARATELY OR TOGETHER.  Awards may, in the
    discretion of the Committee, be granted either alone or in addition to, in
    tandem with, or in substitution for any other Award, except that in no event
    shall an Incentive Stock Option be granted together with a Non-Qualified
    Stock Option in such a manner that the exercise of one Option affects the
    right to exercise the other. Awards granted in addition to or in tandem with
    other Awards may be granted either at the same time as or at a different
    time from the grant of such other awards.
 
        (iii)  FORMS OF PAYMENT UNDER AWARDS.  Subject to the terms of the Plan
    and of any applicable Award Agreement, payments or transfers to be made by
    the Company or an Affiliate upon the grant, exercise or payment of an Award
    may be made in such form or forms as the Committee shall determine,
    including, without limitation, cash, Common Shares, other securities, other
    Awards, or other property, or any combination thereof, and may be made in a
    single payment or transfer, in installments, or on a deferred basis, in each
    case in accordance with rules and procedures established by the Committee.
    Such rules and procedures may include, without limitation, provisions for
    the payment or crediting of reasonable interest on installment or deferred
    payments. In accordance with the above, the Committee may elect (i) to pay a
    Participant (or such Participant's permitted transferee) upon the exercise
    of an Option in whole or in part, in lieu of the exercise thereof and the
    delivery of Common Shares thereunder, an amount of cash equal to the excess,
    if any, of the Fair Market Value of one Common Share on the date of such
    exercise over the exercise price of such Option for one Common Share times
    the number of Common Shares subject to the Option or portion thereof so
    exercised or (ii) to settle other stock denominated Awards in cash.
 
        (iv)  LIMITS ON TRANSFER OF AWARDS.
 
           (A) No award (other than Released Securities), and no right under any
       such Award, may be assigned, alienated, pledged, attached, sold or
       otherwise transferred or encumbered by a Participant otherwise than by
       will or by the laws of descent and distribution (or, in the case of
       Restricted Securities, to the Company) and any such purported assignment,
       alienation, pledge, attachment, sale or other transfer or encumbrance
       shall be void and unenforceable against the Company or any Affiliate.
 
           (B) Each award, and each right under any Award, shall be exercisable,
       during the Participant's lifetime only by the Participant or if
       permissible under applicable law, by the Participant's guardian or legal
       representative.
 
        (v)  TERMS OF AWARDS.  The term of each Award shall be for such period
    as may be determined by the Committee; PROVIDED, HOWEVER, that in no event
    shall the term of any Option exceed a period of ten years from the date of
    its grant.
 
                                      E-8
<PAGE>
        (vi)  RULE 16B-3 SIX-MONTH LIMITATIONS.  To the extent required in order
    to maintain the exemption provided under Rule 16b-3 only, any equity
    security offered pursuant to the Plan must be held for at least six months
    after the date of grant, and with respect to any derivative security issued
    pursuant to the Plan, at least six months must elapse from the date of
    acquisition of such derivative security to the date of disposition of the
    derivative security (other than upon exercise or conversion) or its
    underlying equity security. Terms used in the preceding sentence shall, for
    the purposes of such sentence only, have the meanings, if any, assigned or
    attributed to them under Rule 16b-3.
 
        (vii)  COMMON SHARE CERTIFICATES.  All certificates for Common Shares
    delivered under the Plan pursuant to any Award or the exercise thereof shall
    be subject to such stop transfer orders and other restrictions as the
    Committee may deem advisable under the Plan or the rules, regulations, and
    other requirements of the Securities and Exchange Commission, any stock
    exchange upon which such Common Shares are then listed, and any applicable
    Federal or state securities laws, and the Committee may cause a legend or
    legends to be put on any such certificates to make appropriate reference to
    such restrictions.
 
        (viii)  DELIVERY OF COMMON SHARES OR OTHER SECURITIES AND PAYMENT BY
    PARTICIPANT OF CONSIDERATION. No Common Shares or other securities shall be
    delivered pursuant to any Award until payment in full of any amount required
    to be paid pursuant to the Plan or the applicable Award Agreement is
    received by the Company. Such payment may be made by such method or methods
    and in such form or forms as the Committee shall determine, including,
    without limitation, cash, Common Shares, other securities, other Awards or
    other property, or any combination thereof; PROVIDED that the combined
    value, as determined by the Committee, of all cash and cash equivalents and
    the Fair Market Value of any such Common Shares or other property so
    tendered to the Company, as of the date of such tender, is at least equal to
    the full amount required to be paid pursuant to the Plan or the applicable
    Award Agreement to the Company.
 
    SECTION 7.  AMENDMENTS; ADJUSTMENTS AND TERMINATION.  Except to the extent
prohibited by applicable law and unless otherwise expressly provided in an Award
Agreement or in the Plan:
 
    (a)  AMENDMENTS TO THE PLAN.  The Board may amend, alter, suspend,
discontinue, or terminate the Plan without the consent of any shareholder,
Participant, other holder or beneficiary of an Award, or other Person; PROVIDED,
HOWEVER, that, subject to the Company's rights to adjust Awards under Sections
7(c) and (d), any amendment, alteration, suspension, discontinuation, or
termination that would impair the rights of any Participant, or any other holder
or beneficiary of any Award theretofore granted, shall not to that extent be
effective without the consent of such Participant, other holder or beneficiary
of an Award, as the case may be; and PROVIDED FURTHER, HOWEVER, that
notwithstanding any other provision of the Plan or any Award Agreement, without
the approval of the shareholders of the Company no such amendment, alteration,
suspension, discontinuation, or termination shall be made that would:
 
        (i) increase the total number of Common Shares available for Awards
    under the Plan, except as provided in Section 4 hereof; or
 
        (ii) otherwise cause the Plan to cease to comply with any tax or
    regulatory requirement, including for these purposes any approval or other
    requirement which is or would be a prerequisite for exemptive relief from
    Section 16(b) of the Exchange Act.
 
    (b)  AMENDMENTS TO AWARDS.  The Committee may waive any conditions or rights
under, amend any terms of, or alter, suspend, discontinue, cancel or terminate,
any Award theretofore granted, prospectively or retroactively; PROVIDED,
HOWEVER, that, subject to the Company's rights to adjust Awards under Sections
7(c) and (d), any amendment, alteration, suspension, discontinuation,
cancellation or termination that would impair the rights of any Participant or
holder or beneficiary of any Award theretofore granted, shall not to that extent
be effective without the consent of such Participant or holder or beneficiary of
an Award, as the case may be.
 
    (c)  ADJUSTMENT OF AWARDS UPON CERTAIN ACQUISITIONS.  In the event the
Company or any Affiliate shall assume outstanding employee awards or the right
or obligation to make future such awards in
 
                                      E-9
<PAGE>
connection with the acquisition of another business or another corporation or
business entity, the Committee may make such adjustments, not inconsistent with
the terms of the Plan, in the terms of Awards as it shall deem appropriate in
order to achieve reasonable comparability or other equitable relationship
between the assumed awards and the Awards granted under the Plan as so adjusted.
 
    (d)  ADJUSTMENTS OF AWARDS UPON THE OCCURRENCE OF CERTAIN UNUSUAL OR
NON-RECURRING EVENTS.  The Committee is hereby authorized to make adjustments in
the terms and conditions of, and the criteria included in, Awards in recognition
of unusual or non-recurring events (including, without limitation, the events
described in Section 4(b) hereof) affecting the Company, any Affiliate, or the
financial statements of the Company or any Affiliate, or of changes in
applicable laws, regulations, or accounting principles, whenever the Committee
determines that such adjustments are appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available
under the Plan.
 
    SECTION 8.  GENERAL PROVISIONS.
 
    (a)  NO RIGHT TO AWARDS.  No Employee or other Person shall have any claim
to be granted any Award under the Plan, and there is no obligation for
uniformity of treatment of Employees, or holders or beneficiaries of Awards
under the Plan. The terms and conditions of Awards need not be the same with
respect to each recipient.
 
    (b)  DELEGATION.  Subject to the terms of the Plan and applicable law, the
Committee may delegate to one or more officers or managers of the Company or any
Affiliate, or to a committee of such officers or managers, the authority,
subject to such terms and limitations as the Committee shall determine, to grant
Awards to, or to cancel, modify, waive rights with respect to, alter,
discontinue, suspend, or terminate Awards; PROVIDED, HOWEVER, that, no such
delegation shall be permitted with respect to Awards held by Employees who are
officers or directors of the Company for purposes of Section 16 of the Exchange
Act, or any successor section thereto or who are otherwise subject to such
Section.
 
    (c)  CORRECTION OF DEFECTS, OMISSIONS, AND INCONSISTENCIES.  The Committee
may correct any defect, supply any omission, or reconcile any inconsistency in
the Plan or any Award in the manner and to the extent it shall deem desirable to
carry the Plan into effect.
 
    (d)  WITHHOLDING.  The Company or any Affiliate shall be authorized to
withhold from any Award granted, from any payment due or transfer made under any
Award or under the Plan or from any compensation or other amount owing to a
Participant the amount (in cash, Common Shares, other securities, other Awards,
or other property) of withholding taxes due in respect of an Award, its
exercise, or any payment or transfer under such Award or under the Plan and to
take such other action as may be necessary in the opinion of the Company or
Affiliate to satisfy all obligations for the payment of such taxes.
 
    (e)  NO LIMIT ON OTHER COMPENSATION ARRANGEMENTS.  Nothing contained in the
Plan shall prevent the Company or any Affiliate from adopting or continuing in
effect other or additional compensation arrangements, and such arrangements may
be either generally applicable or applicable only in specific cases.
 
    (f)  NO RIGHT TO EMPLOYMENT.  The grant of an Award shall not be construed
as giving a Participant the right to be retained in the employ of the Company or
any Affiliate. Further, the Company or an Affiliate may at any time dismiss a
Participant from employment, free from any liability, or any claim under the
Plan, unless otherwise expressly provided in the Plan or in any Award Agreement.
 
    (g)  GOVERNING LAW.  The validity, construction, and effect of the Plan and
any rules and regulations relating to the Plan shall be determined in accordance
with the laws of the State of Delaware and applicable Federal law.
 
    (h)  SEVERABILITY.  If any provision of the Plan or any Award is or becomes
or is deemed to be invalid, illegal or unenforceable in any jurisdiction or as
to any Person or Award under any law deemed applicable by the Committee, such
provision shall be construed or deemed amended to conform to applicable laws, or
if it cannot be construed or deemed amended without, in the determination of the
Committee, materially
 
                                      E-10
<PAGE>
altering the intent of the Plan or the Award, such provision shall be stricken
as to such jurisdiction, Person or Award and the remainder of the Plan and any
such Award shall remain in full force and effect.
 
    (i)  NO TRUST OR FUND CREATED.  Neither the Plan nor any Award shall create
or be construed to create a trust or separate fund of any kind or a fiduciary
relationship between the Company or any Affiliate and a Participant or any other
Person. To the extent that any Person acquires a right to receive payments from
the Company or any Affiliate pursuant to an Award, such right shall be no
greater than the right of any unsecured general creditor of the Company or any
Affiliate.
 
    (j)  NO FRACTIONAL COMMON SHARES.  No fractional Common Shares shall be
issued or delivered pursuant to the Plan or any Award, and the Committee shall
determine whether cash, other securities, or other property shall be paid or
transferred in lieu of any fractional Common Shares or whether such fractional
Common Shares or any rights thereto shall be canceled, terminated, or otherwise
eliminated.
 
    (k)  HEADINGS.  Headings are given to the Sections and subsections of the
Plan solely as a convenience to facilitate reference. Such headings shall not be
deemed in any way material or relevant to the construction or interpretation of
the Plan or any provision thereof.
 
    SECTION 9.  ADOPTION, APPROVAL AND EFFECTIVE DATE OF THE PLAN.  The Plan
shall be considered adopted and shall become effective on the date the Plan is
approved by the Board; provided, however, that the Plan and any Awards granted
under the Plan shall be void, if the shareholders of the Company shall not have
approved the adoption of the Plan within twelve (12) months after the effective
date, by a majority of votes cast thereon at a meeting of shareholders duly
called and held for such purpose.
