Item 5.   Other Events.

                  On July 29, 1996 Novametrix Medical Systems Inc., a Delaware
corporation ("Novametrix"), and Andros Holdings Inc., a Delaware corporation
("Andros"), executed an Agreement and Plan of Merger (the "Merger Agreement")
pursuant to which Novametrix Acquisition Corp., a Delaware corporation and a
wholly owned subsidiary of Novametrix, will merge (the "Merger") with and into
Andros, a subsidiary of Genstar Capital Partners II, L.P., a Delaware limited
partnership ("Genstar"). The Merger Agreement is included as an Exhibit to this
Report and the description of its terms is qualified in its entirety by
reference to such Exhibit.

                  Under the Merger Agreement, which has been unanimously
approved by the Boards of Directors of both Novametrix and Andros as well as by
Genstar, as principal stockholder of Andros, 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 45
percent of the combined company at the effective time of the Merger, and (ii)
anti-dilution rights enabling such holders to maintain, without additional
payment, such 45 percent ownership level as Novametrix options and warrants
outstanding at the effective time of the Merger are exercised.

<PAGE>   3
                  William J. Lacourciere, President and Chief Executive Officer
of Novametrix, will continue as the President and Chief Executive Officer of the
combined company, and Richard D. Paterson, a Managing Director of Genstar and
Chairman of Andros, will be the Chairman of the Board of Directors.

                  The Merger, which is subject to customary closing conditions,
including the approval of the stockholders of Novametrix, lenders' consents and
the expiration of the Hart-Scott-Rodino waiting period, is expected to close
during Novametrix' fiscal quarter ending October 27, 1996. The Merger Agreement
provides for each party to pay a termination fee of $3 million under certain
circumstances. Tucker Anthony Incorporated has served as financial advisor to
Novametrix and has delivered an opinion that the transaction consideration is
fair to Novametrix from a financial point of view.

                  Andros is a supplier of instrumentation and a leading
worldwide designer and supplier to original equipment manufacturers of
non-dispersive infrared gas analyzers. Andros sells its products to
manufacturers of medical monitoring equipment, automobile and environmental
diagnostic equipment, and end users of its spectrum analysis instruments.

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

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

         stock or owned by Novametrix or any subsidiary of Novametrix
         immediately prior to the Effective Time shall be cancelled, and no

         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 value (the "Novametrix Preferred Stock"), of

         prior to the Effective Time (assuming the exercise in full of all then
         outstanding Company Options and Company Warrants (each as hereinafter

<PAGE>   7
                                                                               3


         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
<PAGE>   8
                                                                               4

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.

                  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
<PAGE>   9
                                                                               5

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
<PAGE>   10
                                                                               6


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).

                  (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.

                                                                               7


                  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
<PAGE>   12
                                                                               8


(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 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).

                  SECTION 2.03 Directors and Officers. From and after the

such members as may result from director resignations effective at the Effective
Time and (B) an equal number of directors appointed by the Board of Directors of
the Company prior to the Effective Time, one of whom shall be Richard D.

Novametrix, on the one hand, and the members appointed by the Board of Directors
of the Company, on the other hand, as described in clause (iii) above, shall be
as equally distributed as possible among Class A, Class B and Class C Directors

                                  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.
<PAGE>   15
                                                                              11


                  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 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
<PAGE>   16
                                                                              12

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 Services
Limited and (z) Equity Units exercisable for 453.6 Shares or cash, at the
Company's option, as set forth in the EUA Agreements. All outstanding shares of
capital stock of the Company have been duly authorized and validly issued and
are fully paid and nonassessable and free of preemptive rights. Except as set
forth in this Section, there are outstanding as of the date hereof (i) no shares
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
<PAGE>   17
                                                                              13


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 Securities.

                  SECTION 3.07 SEC Filings. (a) The Company has delivered to
Novametrix (i) the annual report on Form 10-K of Andros Incorporated, a Delaware
corporation and wholly owned Subsidiary of the Company ("Andros"), for the
fiscal year ended July 30, 1995 (the "Andros 10-K"), (ii) Andros' quarterly
reports on Form 10-Q for Andros' fiscal quarters ended October 29, 1995 and
January 28, 1996, (iii) Andros' current reports on Form 8-K dated December 28,
1993 and March 25, 1996, (iv) Andros' proxy or information statements relating
to meetings of, or actions taken without a meeting by, the 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 (i)
through (v) above and delivered to Novametrix prior to the date hereof being
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
<PAGE>   18
                                                                              14


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 statements and unaudited consolidated interim financial statements of
the Company and its consolidated Subsidiaries included as Exhibit 3.08 to the
Company Disclosure Schedule and those included in the Andros 10-K and the
quarterly reports on Form 10-Q referred to in Section 3.07 fairly present, in
conformity with generally accepted accounting principles applied on a consistent
basis (except as may be indicated in the notes thereto), the consolidated
financial position of the Company and its consolidated Subsidiaries as of the
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
statements, to normal year-end adjustments, none of which, individually or in
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

                  SECTION 3.11 No Undisclosed Material Liabilities. Except as

                                                                              17


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 of the Company, threatened against the Company or any of its
Subsidiaries or any of their respective properties before any court or
arbitrator or any governmental body, agency or official 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,

                                                                              18

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

                                                                              19


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 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 thereto. Except to the extent that it would not have, or reasonably
be expected to have, individually or in the aggregate, a Company
<PAGE>   24
                                                                              20


Material Adverse Effect, each of the Company's Benefit Arrangements has been
maintained in compliance with its terms and with the requirements prescribed by
any and all statutes, orders, rules and regulations that are applicable to such
Benefit Arrangement.

                  (f) Except to the extent that it would not have, or reasonably
be expected to have, individually or in the aggregate, a Company Material
Adverse Effect, the transactions contemplated hereby will not result in any
liability for severance pay to any employee or accelerate the exercisability or
vesting of any Company Options or Company Warrants, as the case may be, nor will
any employee be entitled to any payment by reason of such transactions or the
termination of such employee within a specified time period after such
transactions.

                  (g) Neither the Company nor any of its Subsidiaries provides,
nor has any of them made any current or past commitment to provide,
post-retirement health or medical benefits for retired employees of the Company
or any of its Subsidiaries.

                  (h) Except as disclosed on Exhibit 3.14(h) to the Company
Disclosure Schedule and subject to the provisions of Section 3.10(h), there has
been no amendment to, written interpretation or announcement (whether or not
written) by the Company or any of its affiliates relating to, or change in
employee participation or coverage under, any Employee Plan or Benefit
Arrangement of the Company which in the aggregate would increase the per
employee expense of maintaining such Employee Plan or Benefit Arrangement above
the level of the expense incurred on a per employee basis in respect thereof for
the six months ended January 28, 1996 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 Company Material Adverse Effect.

                  SECTION 3.15 Compliance with Laws. Except as described in any
Andros SEC Filing, neither the Company nor any of its Subsidiaries is in
violation of, or has violated, any applicable provisions of any laws, statutes,
ordinances or regulations other than violations which would not, in the
aggregate, reasonably be expected to have a Company Material Adverse Effect.

                  SECTION 3.16 Finders' Fees. Except for CS First Boston
("CSFB"), there is no investment banker, broker, finder or other intermediary
which has been retained by or is authorized to act on behalf of the Company or
any of its
<PAGE>   25
                                                                              21


Subsidiaries who might be entitled to any fee or commission in connection with
the transactions contemplated by this Agreement. The Company has heretofore
furnished to Novametrix a complete and correct copy of all agreements between
the Company and CSFB pursuant to which such firm would be entitled to any
payment relating to the transactions contemplated by this Agreement.

                  SECTION 3.17 Vote Required. The affirmative vote of the
holders of a majority of the outstanding Shares is the only vote of the holders
of any class or series of the Company's capital stock necessary to approve this
Agreement and the transactions contemplated hereby and such approval has been
obtained.

                  SECTION 3.18 Intellectual Property. Set forth on Exhibit 3.18
to the Company Disclosure Schedule is a list and brief description of all of the
patents, registered and common law trademarks, service marks, tradenames,
copyrights, licenses and other similar rights of the Company and its
Subsidiaries. The Company or one of its Subsidiaries, as applicable, owns all
right, title and interest in and to all such proprietary rights. The proprietary
rights listed are all such rights necessary to the conduct of the business of
the Company 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 the Company and its Subsidiaries
and the use by the Company 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. The Company has taken
reasonable measures to maintain the confidentiality of the processes and
formulae, research and development and other know-how of the Company, the value
of which to the Company is dependent upon the maintenance of the confidentiality
thereof. Neither the Company nor any of its Subsidiaries has licensed or
otherwise permitted the use by any third party of any proprietary information on
terms or in a manner that is reasonably likely to have a Company Material
Adverse Effect.

                  SECTION 3.19 Permits; Company Products; Regulation. (a) Except
as disclosed on Exhibit 3.19(a)(i) to the Company Disclosure Schedule, the
Company and each of its Subsidiaries is in possession of all franchises, grants,
authorizations, licenses, permits, easements, variances, exceptions, consents,
certificates, approvals and orders of any governmental body, agency, official or
authority necessary for the Company or such Subsidiary, as applicable, to own,
lease and operate its properties or to carry on its

                                                                              22


business as it is now being conducted (the "Company Permits"), and no suspension
or cancellation of any of the Company Permits is pending or, to the knowledge
any of the officers of the Company or any of its Subsidiaries, threatened,
except where the failure to have, or the suspension or cancellation of, any of
the Company Permits would not have a Company Material Adverse Effect. A list of
the material Company Permits is set forth on Exhibit 3.19(a)(ii) to the Company
Disclosure Schedule. Except as disclosed on Exhibit 3.19(a)(i) to the Company
Disclosure Schedule, neither the Company nor any of its Subsidiaries is in
default under or violation of (i) any law, regulation, judgment, injunction,
order or decree applicable to the Company or any of its Subsidiaries or by which
any property or asset of the Company or any of its Subsidiaries is bound or
affected, (ii) any of the Company Permits or (iii) any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation to which the Company or any of its Subsidiaries is a
party or by which the Company or any of its Subsidiaries or any property or
asset of the Company or any of its Subsidiaries is bound or affected, except for
defaults or violations that, individually or in the aggregate, would not have a
Company Material Adverse Effect.

                  (b) Except as disclosed on Exhibit 3.19(b) to the Company
Disclosure Schedule and except as would not have a Company Material Adverse
Effect, since July 30, 1995, there have been no written notices, citations or
decisions by any governmental or regulatory body that any product produced,
manufactured or marketed at any time by the Company or any of its Subsidiaries
(the "Company Products"), other than a Company Third Party Product (as defined
below) is defective or fails to meet any applicable standards promulgated by any
such governmental or regulatory body, and no officer of the Company or any of
its Subsidiaries knows of any such defect or failure. In the case of products
which are produced or manufactured by third parties and are distributed by the
Company or any of its Subsidiaries (the "Company Third Party Products"), to the
knowledge of any of the officers of the Company or any of its Subsidiaries,
there have been no written notices, citations or decisions by any governmental
or regulatory body that any Company Third Party Product distributed at any time
by the Company or any of its Subsidiaries is defective or fails to meet any
applicable standards promulgated by any such governmental or regulatory body,
and none of the officers of the Company or any of its Subsidiaries knows of any
such defect or failure. The Company and each of its Subsidiaries has complied
with the laws, regulations, policies, procedures and specifications applicable
to the Company or such Subsidiary, as applicable,
<PAGE>   27
                                                                              23


with respect to the design, manufacture, labelling, testing and inspection of
Company Products in the United States and the operation of manufacturing
facilities in the United States promulgated by the Food and Drug Administration
(the "FDA"), and has complied with the laws, regulations, policies, procedures
and specifications applicable to the Company or such Subsidiary, as applicable,
in any jurisdiction outside the United States with respect to the design,
manufacture, labelling, testing and inspection of Company Products and the
operation of manufacturing facilities outside of the United States except for
such non-compliance as would not have a Company Material Adverse Effect. Except
as disclosed on Exhibit 3.19(b) to the Company Disclosure Schedule, since July
30, 1995, there have been no recalls, field notifications or seizures ordered
or, to the knowledge of any of the officers of the Company or any of its
Subsidiaries, threatened by any such governmental or regulatory body with
respect to any of the Company Products, other than Company Third Party Products,
and neither the Company nor any of its Subsidiaries has independently engaged in
recalls or field notifications. In the case of Company Third Party Products
distributed by the Company or any of its Subsidiaries, neither the Company nor
any of its Subsidiaries has received any notices of any recalls, field
notifications or seizures ordered or threatened by any such governmental or
regulatory body with respect to any of such Company Third Party Products, and
neither the Company nor any of its Subsidiaries has independently engaged in
recalls or field notifications. Except as set forth on Exhibit 3.19(b) to the
Company Disclosure Schedule, neither the Company nor any of its Subsidiaries has
received, and to the knowledge of any of the officers of the Company or any of
its Subsidiaries, there is no reasonable basis for, any warning letter or
Section 305 notices from the FDA.

                  (c) Except as set forth on Exhibit 3.19(c)(i) to the Company
Disclosure Schedule, the Company or one or more of its Subsidiaries has

regulating the safety, effectiveness and market clearance of the Company
Products that are currently marketed by the Company or such Subsidiary, as
applicable, except where the failure to obtain such licenses, registrations,
approvals, clearances and authorizations would not have a Company Material
Adverse Effect. The Company has made available to Novametrix all information
relating to the Company Products

hereof and pursuant to Section 203(a)(1) and (b)(4) of the Delaware Law, the

                  REPRESENTATIONS AND WARRANTIES OF NOVAMETRIX

                  Novametrix represents and warrants to the Company that:

                  SECTION 4.01 Corporate Existence and Power. Novametrix 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 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 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.

         SECTION 4.02 Corporate Authorization. The execution, delivery and

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

Novametrix Material Adverse Effect.

         (b) Except as disclosed on Exhibit 4.06(b) to the Novametrix Disclosure
Schedule, all of the outstanding capital stock of each Subsidiary of Novametrix

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 Novametrix (the items in clauses (i) and (ii)
being referred to collectively as the "Novametrix Subsidiary Securities"). There

                  (i) any labor dispute, other than individual grievances, which
         would have a Novametrix Material Adverse Effect, or any activity or
         proceeding by a labor union or representative thereof to organize any
         employees of Novametrix or any of its Subsidiaries, which employees
         were not subject to a collective bargaining agreement at April 28, 1996
         or any lockouts, strikes, slowdowns, work stoppages or threats thereof
         by or with respect to such employees;

                  (j) any actual or, to Novametrix' knowledge, threatened
         dispute between Novametrix or any of its Subsidiaries and any vendor or
         customer, other than disputes which would not have or reasonably be
         expected to have, individually or in the aggregate, a Novametrix
         Material Adverse Effect;

                  (k) any actual or, to Novametrix' knowledge, threatened
         suspension or cancellation of any governmental license, permit,
         authorization, consent or approval, other than those the suspension or
         cancellation of which would not have or reasonably be expected to have,
         individually or in the aggregate, a Novametrix Material Adverse Effect;
         or

                  (l) any change in any Federal or state law, rule or regulation
         applicable to Novametrix or any of its Subsidiaries, or in the
         interpretation or application thereof, which individually or in the
         aggregate has had or would reasonably be expected to have a Novametrix
         Material Adverse Effect.

         SECTION 4.10 No Undisclosed Material Liabilities. Except as described
in any Novametrix SEC Filing or on Exhibit 4.10 to the Novametrix Disclosure
Schedule, there are no liabilities of Novametrix 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 Novametrix Material Adverse Effect, other than:

                  (i) liabilities incurred in the ordinary course of business
         consistent with past practices since April 28, 1996, which in the
         aggregate are not material
<PAGE>   35
                                                                              31

         to Novametrix and its Subsidiaries, taken as a whole; and

                  (ii) liabilities under this Agreement.

         SECTION 4.11 Litigation. Except as described in the Novametrix 10-KSB
or as disclosed on Exhibit 4.11 to the Novametrix Disclosure Schedule, there is
no action, suit, investigation or proceeding pending against, or to the
knowledge of Novametrix threatened against, Novametrix or any of its
Subsidiaries or any of their respective properties before any court or
arbitrator or any governmental body, agency or official which would have or
reasonably be expected to have, individually or in the aggregate, a Novametrix
Material Adverse Effect. To the best of the knowledge of Novametrix, 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 Novametrix or any of its Subsidiaries which
could reasonably be expected to have, individually or in the aggregate, a
Novametrix Material Adverse Effect.

         SECTION 4.12 Taxes. (i) Novametrix 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 Novametrix 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 Novametrix Material Adverse Effect; and
(iii) neither Novametrix nor any of its Subsidiaries is liable and it is not
reasonably likely that Novametrix or any of its Subsidiaries will be liable for
any taxes not reserved against in Novametrix' consolidated balance sheet as of
April 28, 1996 included in the Novametrix 10-KSB except those which would not
have or reasonably be expected to have, individually or in the aggregate, a
Novametrix Material Adverse Effect.

         SECTION 4.13 ERISA. (a) "Novametrix Employee Plans" shall mean each
"employee benefit plan", as defined in Section 3(3) of ERISA, which (i) is
subject to any provision of ERISA and (ii) is maintained, administered or
contributed to by Novametrix or any affiliate (as defined in Section 3.14(a))
and covers any employee or former employee of Novametrix or any affiliate or
under which Novametrix or
<PAGE>   36
                                                                              32

any affiliate has any liability. No Novametrix Employee Plan individually or
collectively constitutes a "defined benefit plan" as defined in Section 3(35) of
ERISA.

         (b) No Novametrix Employee Plan constitutes a "multi-employer plan", as
defined in Section 3(37) of ERISA, and no Novametrix Employee Plan is maintained
in connection with any trust described in Section 501(c)(9) of the Code. No
Novametrix Employee Plan is subject to Title IV of ERISA. Neither Novametrix 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 Novametrix Material Adverse Effect. Nothing done or omitted to
be done and no transaction or holding of any asset under or in connection with
any Novametrix Employee Plan has or will make Novametrix or any of its
Subsidiaries or any officer or director of Novametrix 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 Novametrix Material Adverse Effect.

         (c) Except as disclosed on Exhibit 4.13(c) to the Novametrix Disclosure
Schedule and except to the extent it would not have, or reasonably be expected
to have, individually or in the aggregate, a Novametrix Material Adverse Effect,
(i) each Novametrix 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 forming a part thereof is
exempt from tax pursuant to Section 501(a) of the Code, and (ii) each Novametrix
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 that it would not have, or reasonably be
expected 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.
<PAGE>   37
                                                                              33

         (e) Copies or descriptions of Novametrix' Benefit Arrangements have
been furnished to the Company. Exhibit 4.13(e) to the Novametrix Disclosure
Schedule sets forth all outstanding Novametrix Options as of the date hereof,
including the applicable exercise price with respect thereto. Except to the
extent that it would not have, or reasonably be expected to have, individually
or in the aggregate, a Novametrix Material Adverse Effect, each of Novametrix'
Benefit Arrangements has been maintained in compliance with its terms and with
the requirements prescribed by any and all statutes, orders, rules and
regulations that are applicable to such Benefit Arrangement.

         (f) Except to the extent it would not have, or reasonably be expected
to have, individually or in the aggregate, a Novametrix Material Adverse Effect,
the transactions contemplated hereby will not result in any liability for
severance pay to any employee or accelerate the exercisability or vesting of any
Novametrix Options, nor will any employee be entitled to any payment by reason
of such transactions or the termination of such employee within a specified time
period after such transactions.

         (g) Neither Novametrix nor any of its Subsidiaries provides, nor has
any of them made any current or past commitment to provide, post-retirement
health or medical benefits for retired employees of Novametrix or any of its
Subsidiaries.

         (h) Except as disclosed on Exhibit 4.13(h) to the Novametrix Disclosure
Schedule and subject to the provisions of Section 4.09(h), there has been no
amendment to, written interpretation or announcement (whether or not written) by
Novametrix or any of its affiliates relating to, or change in employee
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.

         SECTION 4.14 Compliance with Laws. Except as described in any
Novametrix SEC Filing, neither Novametrix nor any of its Subsidiaries is in
violation of, or has violated, any applicable provisions of any laws, statutes,
ordinances or regulations other than violations which would
<PAGE>   38
                                                                              34

not, in the aggregate, reasonably be expected to have a Novametrix Material
Adverse Effect.

         SECTION 4.15 Finders' Fees. Except for Tucker Anthony Incorporated
("Tucker"), there is no investment banker, broker, finder or other intermediary
which has been retained by or is authorized to act on behalf of Novametrix or
any of its Subsidiaries who might be entitled to any fee or commission in
connection with the transactions contemplated by this Agreement. Novametrix has
heretofore furnished to the Company a complete and correct copy of all
agreements between Novametrix and Tucker pursuant to which such firm would be
entitled to any payment relating to the transactions contemplated by this
Agreement.

         SECTION 4.16 Opinion of Financial Advisor. Novametrix has received the
oral opinion of Tucker to the effect that as of the date hereof the Merger
Consideration is fair to Novametrix from a financial point of view, and a copy
of the written opinion to such effect shall be delivered to the Company prior to
August 3, 1996.

         SECTION 4.17 Vote Required. The affirmative vote of the holders of a
majority of the voting power represented by the shares of Novametrix Common
Stock and Novametrix Preferred Stock (voting together as a single class) voted
at a meeting of stockholders is the only vote of the holders of any class or
series of Novametrix' capital stock necessary to approve this Agreement and the
transactions contemplated hereby.

         SECTION 4.18 Intellectual Property. Set forth on Exhibit 4.18 to the
Novametrix Disclosure Schedule is a list and brief description of all of the
patents, registered and common law trademarks, service marks, tradenames,
copyrights, licenses and other similar rights of Novametrix and its
Subsidiaries. Novametrix or one of its Subsidiaries, as applicable, owns all
right, title and interest in and to all such proprietary rights. The proprietary
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
formulae, research and development and other know-how of
<PAGE>   39
                                                                              35

Novametrix, the value of which to Novametrix is dependent upon the maintenance
of the confidentiality thereof. Neither Novametrix nor any of its Subsidiaries
has licensed or otherwise permitted the use by any third party of any
proprietary information on terms or in a manner that is reasonably likely to
have a Novametrix Material Adverse Effect.

         SECTION 4.19 Permits; Company Products; Regulation. (a) Except as
disclosed on Exhibit 4.19(a)(i) to the Novametrix Disclosure Schedule,
Novametrix and each of its Subsidiaries is in possession of all franchises,
grants, authorizations, licenses, permits, easements, variances, exceptions,
consents, certificates, approvals and orders of any governmental body, agency,
official or authority necessary for Novametrix or such Subsidiary, as
applicable, to own, lease and operate its properties or to carry on its business
as it is now being conducted (the "Novametrix Permits"), and no suspension 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
where the failure to have, or the suspension or cancellation of, any of the
Novametrix Permits would not have a Novametrix Material Adverse Effect. A list
of the material Novametrix Permits is set forth on Exhibit 4.19(a)(ii) to the
Novametrix Disclosure Schedule. Except as disclosed on Exhibit 4.19(a)(i) to the

regulating the safety, effectiveness and market clearance of the Novametrix
Products in such countries that are currently marketed by Novametrix or such
Subsidiary, as applicable, except where the failure to obtain such licenses,
registrations, approvals, clearances and authorizations would not have a
Novametrix Material Adverse Effect. Novametrix has made available to the Company

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

announced, and not withdrawn, a proxy contest, tender offer, exchange offer,
merger or other Novametrix Acquisition Proposal (the "Pre-Termination

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 (any such transaction being a
"Post-Termination 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' entering into or becoming the subject of a Post-Termination

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

                                                                               2


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 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.

                                                                               3


                  (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

                                                                               4


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.

                  (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
<PAGE>   74
                                                                               5


         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,
<PAGE>   75
                                                                               6

         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
         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
<PAGE>   76
                                                                               7


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

                                                                               8


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 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.
<PAGE>   78
                                                                               9


                  (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
<PAGE>   79
                                                                              10


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 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
<PAGE>   80
                                                                              11


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
<PAGE>   81
                                                                              12


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.

                  (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
<PAGE>   82
                                                                              13


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
<PAGE>   83
                                                                              14


from any other obligation it or they may have under this Section 1(q). No party
will be liable for 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
<PAGE>   84
                                                                              15

         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,
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
<PAGE>   85
                                                                              16


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
<PAGE>   86
                                                                              17

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.

                  (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.

     NOVAMETRIX Medical Systems And ANDROS To Merge; Merger Will Create A
       Leader In Medical Instrumentation

  WALLINGFORD, Conn., and BERKELEY, Calif. -- (BUSINESS WIRE) -- JULY 30, 1996
- -- NOVAMETRIX MEDICAL SYSTEMS INC. (NASDAQ: NMTX) and ANDROS INC. jointly
announced today that they have executed a definitive merger agreement pursuant
to which Novametrix will acquire all of the outstanding common stock of Andros,
a subsidiary of Genstar Capital Partners II, L.P.

  Under the merger agreement, which has been unanimously approved by the Boards
of Directors of both companies, 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 45 percent of the
combined company at closing, and (ii) anti-dilution rights enabling the holders
to maintain, without additional payment, such 45 percent ownership level as
Novametrix options and warrants outstanding at closing are exercised.

  The transaction will create a world leader in the field of gas monitoring
products and sensor technology for medical applications. The combined company,
which will retain the Novametrix name, would have sales of $67.0 million for
the fiscal year ended April 28, 1996, on a pro forma basis, as compared to
Novametrix' stand-alone sales of $25.3 million for the same period.
Approximately two-thirds of the combined company's revenues are expected to
come from the sale of medical related products.

  Both Novametrix and Andros specialize in non-dispersive infrared gas analysis
technology, Novametrix having historically applied its technology to medical
instrumentation and Andros having applied its technology to both medical
instrumentation and environmental/automotive diagnostic products. The combined
company will have significant technological synergies and will expand the
market for each company's products and technologies to the combined customer
base. Andros' technology for monitoring anesthetic agents complements
Novametrix' technology for monitoring oxygen and carbon dioxide and respiratory
mechanics. In addition, there are significant opportunities to apply
Novametrix' technologies to Andros' automotive and environmental
instrumentation businesses.

  William J. Lacourciere, president and CEO of Novametrix, will continue as the
president and chief executive officer of the combined company, and Richard D.
Paterson, a managing director of Genstar and chairman of Andros, will be the
chairman of the Board of Directors.

  Lacourciere stated that "the merger will nearly triple the revenues of
Novametrix and should result in substantial earnings accretion for the
Novametrix stockholders, even before taking into account efficiencies and cost
savings which we believe can be achieved after the merger. In addition, the
merger will broaden and strengthen our technology base, providing additional
leverage with national accounts, and will result in diversification of our
markets." Lacourciere continued, "Andros is a natural fit with Novametrix, with
the combination providing many complementary technologies and a world-class
customer base, including the world's major manufacturers of medical monitoring
equipment. Novametrix will become the world's largest OEM supplier of gas
monitoring products for medical applications. Also, we welcome Genstar as a
partner in our ongoing effort to maximize shareholder value."

  Paterson stated that "the merger of Novametrix and Andros will create a
larger and more efficient manufacturer and marketer of medical patient
monitoring equipment. The merger broadens and further enhances the already
close relationships each company has with a customer base composed of some of
the most respected OEMs in the medical products industry. Moreover, we

believe there are significant synergies between the two companies' infrared
technology development groups that will accelerate the combined company's
development of leading edge products for their respective markets. Bill
Lacourciere is a strong manager and motivator of people and is uniquely
qualified to lead the combined technology company. Novametrix' reputation for
the quality of its products and services and the excellence of its technologies
should enhance the ability of the combined company to compete in the medical,
automotive and environmental instrumentation markets. Genstar is enthusiastic
about its proposed investment in the combined company and looks forward to
working with management to enhance the value of the combined company."

        The merger, which is subject to customary closing conditions, including
the approval of the shareholders of Novametrix, lenders' consents, and the
expiration of the Hart-Scott-Rodino waiting period, is expected to close during
Novametrix' fiscal quarter ending October 27, 1996. The merger agreement
provides for each party to pay a termination fee of $3 million under certain
circumstances. Tucker Anthony Inc. has served as financial advisor to
Novametrix and has delivered an opinion that the transaction consideration is
fair to Novametrix from a financial point of view.

        This press release contains forward looking information about the
combined company's projected operating results for fiscal 1996 and the combined
company's plans for achieving such results. The combined company's ability to
achieve its projected results is dependent on a variety of factors, many of
which are outside management's control. Some of the most significant factors,
alone or in combination, would be the failure to integrate the businesses of
Novametrix and Andros successfully, an unanticipated slowdown in the health
care, automotive or environmental industries (as a result of cost containment
measures, changes in government regulation or other factors), unanticipated
technological developments which affect the competitiveness of the combined
company's products, or the unanticipated loss of business. Accordingly there
can be no assurance that the combined company will achieve its projected
operating results.
