                  STOCKHOLDERS AGREEMENT dated as of September 30, 1997 (this
"Agreement") among Novametrix Medical Systems Inc., a Delaware corporation (the
"Corporation"), and the stockholders of the Corporation signing this Agreement
(the "Stockholders").


                              W I T N E S S E T H:


                  WHEREAS, each of the Stockholders is the beneficial owner of
the number of shares of common stock, $.01 par value ("Common Stock"), of the
Corporation, Class A Warrants to purchase the number of shares of Common Stock
("A Warrants") and Class B Warrants to purchase the number of shares of Common
Stock ("B Warrants") set forth opposite such Stockholder's name on the signature
page hereto and is a member of a group (the "13D Group") which has filed a
statement in respect of their holdings of the Corporation's securities on
Schedule 13D under the Securities Exchange Act of 1934, as amended (the
"Exchange Act").

                  NOW, THEREFORE, in consideration of the mutual benefits to be
derived and the conditions and promises herein contained, and intending to be
legally bound hereby, the parties hereto agree as follows:

                  1. Voting Agreement. The Corporation agrees that the 1997
annual meeting (the "1997 Meeting") of the Corporation's stockholders will be
held not later than October 14, 1997. Provided that none of the executive
officers of the Corporation has actual knowledge of any Solicitation (as
hereinafter defined) relating to the Corporation on the date hereof which
Solicitation is not publicly supported by a resolution of a majority of the
current members of the Board of Directors of the Corporation (a "Dissident
Solicitation"), each of the Stockholders, for the benefit of the Corporation and
as an inducement to the Corporation to enter into this Agreement, agrees to vote
or cause to be voted at the 1997 Meeting all of the shares of Common Stock which
he or she has the right to vote and of which he or she has the right to direct
the vote in favor of persons (the "Continuing Director Nominees") who shall be
nominated as directors by a majority of the current directors of the
Corporation. Immediately upon any of the executive officers of the Corporation
obtaining actual knowledge of any Dissident Solicitation, the Corporation shall
inform the Stockholder Representative of such Dissident Solicitation. The terms
"Solicitation" and "Solicit" shall mean (i) any solicitation (within the

                                                                               2




meaning of the Exchange Act) of a proxy (as defined in the Exchange Act), (ii)
any request for a proxy, whether or not accompanied, preceded or followed by a
proxy or included in a form of proxy, (iii) any request or recommendation to
execute or not to execute, or to revoke or not to revoke, a proxy, (iv) the
furnishing of a form of proxy or other communication to security holders under
circumstances reasonably calculated to result in the procurement, withholding or
revocation of a proxy or (v) any public statement, favorable or unfavorable,
regarding any proposal, nominee or other matter in any proxy.

                  2. The 13D Director. (a) Provided that (i) none of the
Stockholders shall have breached any of their agreements hereunder and (ii)
there shall not have been a Dissident Solicitation, then the Corporation shall
use its best efforts to cause the Board of Directors of the Corporation (x) to
increase by one the number of Class C directors of the Corporation and to elect
John P. Mahoney, M.D. (the "13D Director") as a Class C director of the
Corporation at a meeting of the Board of Directors to be held within 24 hours of
the adjournment of the 1997 Meeting and (y) to nominate the 13D Director for
reelection as a Class C director at the 1998 annual meeting of the Corporation's
stockholders. Attached hereto as Annex A is a form of the agreement of the
current directors of the Corporation concerning this Section 2; such form of
agreement, executed by a majority of the current directors of the Corporation,
is being delivered to the Stockholders contemporaneously herewith.

                  (b) Notwithstanding the foregoing, if the Stockholders shall
at any time beneficially own (within the meaning of Rule 13d-3 under the
Exchange Act) in the aggregate less than five percent (5%) of the shares of
Common Stock outstanding or 460,270 shares of Common Stock, whichever is less,
then the Stockholders shall have no further rights under this Section 2 and the
13D Director shall promptly resign as a director of the Corporation. The 13D
Director has executed a contingent resignation in the form of Annex B hereto.

                  3. By-law Amendment. The amendment to the By-laws of the
Corporation set forth on Annex C hereto will be proposed for adoption at the
next meeting of the Board of Directors of the Corporation. Each of the
Stockholders agrees that such amendment is appropriate and agrees not to oppose
or challenge its adoption.

                                                                               3





                  4.       Appointment of Stockholder Representative.

                  (a) Each Stockholder hereby makes, constitutes and appoints
John P. Mahoney, M.D. 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 or
herself, 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 to be received or which may be received under this Agreement. The incapacity
of any Stockholder shall not terminate the agency and power of attorney granted
hereby to the Stockholder Representative. Upon the death of any Stockholder,
such Stockholder's executors, administrators, legal representatives and heirs
may only exercise rights under this Agreement through the Stockholder
Representative as their sole and exclusive agent. Such agency and power of
attorney is irrevocable and coupled with an interest, and the provisions of this
Section 4 are independent and severable and shall be enforceable notwithstanding
any rights or remedies that any Stockholder may have in connection with, or in
any way arising out of, the transactions contemplated by this Agreement. The
obligations hereunder of Dr. Mahoney, as representative, shall not be terminated
by operation of law, whether by his death or incapacity or by the occurrence of
any other event. In the event Dr. Mahoney should die or become incapacitated, or
for any other reason become unable to perform his 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

                                                                               4




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 his role as such, except for any action or
omission taken or made fraudulently or in bad faith with respect to such
Stockholder.

                  5.       No Solicitation.

                  (a) From the date hereof through the date of the 1997 Meeting,
none of the Stockholders and none of their respective affiliates or associates
shall become, provide information to or assist a Participant (as hereinafter
defined) in any Dissident Solicitation. The term "Participant" shall mean (i)
any committee or group which Solicits proxies, any member of such committee or
group, and any person whether or not named as a member who, acting alone or with
one or more other persons, directly or indirectly takes the initiative, or
engages, in organizing, directing or arranging for the financing of any such
committee or group; (ii) any person who finances or joins with another to
finance the Solicitation of proxies; (iii) any person who lends money or
furnishes credit or enters into any other arrangements, pursuant to any contract
or understanding with a Participant, for the purpose of financing or otherwise
inducing the purchase, sale, holding or voting of securities of the Corporation
by any Participant or other persons, in support of or in opposition to a
Participant; and (iv) any person who Solicits proxies. The terms "affiliate" and
"associate" shall have the respective meanings ascribed to such terms in Rule
12b-2 under the Exchange Act, as in effect on the date hereof.

                  (b) This Section 5 shall not be deemed to amend or modify in
any way that certain Rights Agreement dated as of March 14, 1989, as amended,
between the Corporation and the rights agent thereunder.

                  6. Public Announcements. Subject to Section 5(a), each of the
Stockholders will consult with the Corporation before issuing any press release
or making any public statement with respect to this Agreement or any of the
transactions contemplated hereby.

the Corporation, consolidation, merger or reorganization of the Corporation.
