GUARANTY

        GUARANTY, dated as of June 30, 2003, by ALARIS RELEASE CORPORATION,
ALARIS CONSENT CORPORATION, RIVER MEDICAL, INC., IVAC OVERSEAS HOLDINGS, INC.
and each other entity listed on the signature pages hereof or that becomes a
party hereto pursuant to Section 24 (Additional Guarantors) hereof (each a
“Guarantor” and, collectively, the “Guarantors”), in favor of the Administrative
Agent, each Lender, each Issuer and each other holder of an Obligation (as each
such term is defined in the Credit Agreement referred to below) (each, a
“Guarantied Party” and, collectively, the “Guarantied Parties”).

W I T N E S S E T H:

        WHEREAS, pursuant to the Credit Agreement, dated as of June 30, 2003 (as
the same may be amended, restated, supplemented or otherwise modified from time
to time, the “Credit Agreement”), among ALARIS Medical Systems, Inc. (the
“Borrower”), the Lenders and the Issuers party thereto and Citicorp North
America Inc., as agent for the Lenders and the Issuers, UBS Securities LLC, as
syndication agent for the Lenders and the Issuers, and Bear Stearns Corporate
Lending Inc. and CIBC World Markets Corp., as co-documentation agents for the
Lenders and the Issuers, the Lenders and the Issuers have severally agreed to
make extensions of credit to the Borrower upon the terms and subject to the
conditions set forth therein;

        WHEREAS, each Guarantor is a direct or indirect Domestic Subsidiary of
the Borrower;

        WHEREAS, each Guarantor will receive direct or indirect benefits from
the making of the Loans, the issuance of the Letters of Credit and the granting
of the other financial accommodations to the Borrower under the Credit
Agreement; and

        WHEREAS, it is a condition precedent to the obligation of the Lenders
and the Issuers to make their respective extensions of credit to the Borrower
under the Credit Agreement that the Guarantors shall have executed and delivered
this Guaranty for the benefit of the Guarantied Parties;

        NOW, THEREFORE, in consideration of the premises set forth above, the
terms and conditions contained herein, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto hereby agree as follows:

      Section 1 Guaranty

(a)     To induce the Lenders to make the Loans and the Issuers to issue Letters
of Credit, each Guarantor hereby absolutely, unconditionally and irrevocably
guarantees, jointly with the other Guarantors and severally, as primary obligor
and not merely as surety, the full and punctual payment when due, whether at
stated maturity or earlier, by reason of acceleration, mandatory prepayment or
otherwise in accordance herewith or any other Loan Document, of all the
Obligations, whether or not from time to time reduced or extinguished or
hereafter increased or incurred, whether or not recovery may be or hereafter may
become barred by any statute of limitations, whether or not enforceable as
against the Borrower, whether now or hereafter existing, and whether due or to
become due, including principal, interest (including interest at the contract
rate applicable upon default accrued or accruing after the commencement of any
proceeding under the Bankruptcy Code or any applicable provisions of comparable
state or foreign law, whether or not such interest is an allowed claim in such
proceeding), fees and costs of collection. This Guaranty constitutes a guaranty
of payment and not of collection.

(b)     Each Guarantor further agrees that, if (i) any payment made by Borrower
or any other Person and applied to the Obligations is at any time annulled,
avoided, set aside, rescinded, invalidated, declared to be fraudulent or
preferential or otherwise required to be refunded or repaid, or (ii) the
proceeds of Collateral are required to be returned by any Guarantied Party to
the Borrower, its estate, trustee, receiver or any other party, including any
Guarantor, under any bankruptcy law, equitable cause or any other Requirement of
Law, then, to the extent of such payment or repayment, any such Guarantor’s
liability hereunder (and any Lien or other Collateral securing such liability)
shall be and remain in full force and effect, as fully as if such payment had
never been made. If, prior to any of the foregoing, this Guaranty shall have
been cancelled or surrendered (and if any Lien or other Collateral securing such
Guarantor’s liability hereunder shall have been released or terminated by virtue
of such cancellation or surrender), this Guaranty (and such Lien or other
Collateral) shall be reinstated in full force and effect, and such prior
cancellation or surrender shall not diminish, release, discharge, impair or
otherwise affect the obligations of any such Guarantor in respect of the amount
of such payment (or any Lien or other Collateral securing such obligation).

      Section 2 Limitation of Guaranty

        Any term or provision of this Guaranty or any other Loan Document to the
contrary notwithstanding, the maximum aggregate amount of the Obligations for
which any Guarantor shall be liable shall not exceed the maximum amount for
which such Guarantor can be liable without rendering this Guaranty or any other
Loan Document, as it relates to such Guarantor, subject to avoidance under
applicable law relating to fraudulent conveyance or fraudulent transfer
(including Section 548 of the Bankruptcy Code or any applicable provisions of
comparable state law) (collectively, “Fraudulent Transfer Laws”), in each case
after giving effect (a) to all other liabilities of such Guarantor, contingent
or otherwise, that are relevant under such Fraudulent Transfer Laws
(specifically excluding, however, any liabilities of such Guarantor in respect
of intercompany Indebtedness to the Borrower to the extent that such
Indebtedness would be discharged in an amount equal to the amount paid by such
Guarantor hereunder) and (b) to the value as assets of such Guarantor (as
determined under the applicable provisions of such Fraudulent Transfer Laws) of
any rights to subrogation, contribution, reimbursement, indemnity or similar
rights held by such Guarantor pursuant to (i) applicable Requirements of Law,
(ii) Section 3 (Contribution) of this Guaranty or (iii) any other Contractual
Obligations providing for an equitable allocation among such Guarantor and other
Subsidiaries or Affiliates of the Borrower of obligations arising under this
Guaranty or other guaranties of the Obligations by such parties.

      Section 3 Contribution

        To the extent that any Guarantor shall be required hereunder to pay a
portion of the Obligations exceeding the greater of (a) the amount of the
economic benefit actually received by such Guarantor from the Revolving Loans,
the Term Loans and the other financial accommodations provided to the Borrower
under the Credit Agreement and (b) the amount such Guarantor would otherwise
have paid if such Guarantor had paid the aggregate amount of the Obligations
(excluding the amount thereof repaid by the Borrower) in the same proportion as
such Guarantor’s net worth at the date enforcement is sought hereunder bears to
the aggregate net worth of all the Guarantors at the date enforcement is sought
hereunder, then such Guarantor shall be reimbursed by such other Guarantors for
the amount of such excess, pro rata, based on the respective net worths of such
other Guarantors at the date enforcement hereunder is sought.

      Section 4 Authorization; Other Agreements

        The Guarantied Parties are hereby authorized, without notice to, or
demand upon, any Guarantor, which notice and demand requirements each are
expressly waived hereby, and without discharging or otherwise affecting the
obligations of any Guarantor hereunder (which obligations shall remain absolute
and unconditional notwithstanding any such action or omission to act), from time
to time, to do each of the following:

(a)     supplement, renew, extend, accelerate or otherwise change the time for
payment of, or other terms relating to, the Obligations, or any part of them, or
otherwise modify, amend or change the terms of any promissory note or other
agreement, document or instrument (including the other Loan Documents) now or
hereafter executed by the Borrower and delivered to the Guarantied Parties or
any of them, including any increase or decrease of principal or the rate of
interest thereon;

(b)     waive or otherwise consent to noncompliance with any provision of any
instrument evidencing the Obligations, or any part thereof, or any other
instrument or agreement in respect of the Obligations (including the other Loan
Documents) now or hereafter executed by the Borrower and delivered to the
Guarantied Parties or any of them;

(c)     accept partial payments on the Obligations;

(d)     receive, take and hold additional security or collateral for the payment
of the Obligations or any part of them and exchange, enforce, waive, substitute,
liquidate, terminate, abandon, fail to perfect, subordinate, transfer, otherwise

(e)     settle, release, compromise, collect or otherwise liquidate the
Obligations or accept, substitute, release, exchange or otherwise alter, affect
or impair any security or collateral for the Obligations or any part of them or
any other guaranty therefor, in any manner;

(f)     add, release or substitute any one or more other guarantors, makers or
endorsers of the Obligations or any part of them and otherwise deal with the
Borrower or any other guarantor, maker or endorser;

(g)     apply to the Obligations any payment or recovery (x) from the Borrower,
from any other guarantor, maker or endorser of the Obligations or any part of
them or (y) from any Guarantor in such order as provided herein, in each case
whether such Obligations are secured or unsecured or guaranteed or not
guaranteed by others;

(h)     apply to the Obligations any payment or recovery from any Guarantor of
the Obligations or any sum realized from security furnished by such Guarantor
upon its indebtedness or obligations to the Guarantied Parties or any of them,
in each case whether or not such indebtedness or obligations relate to the
Obligations; and

(i)     refund at any time any payment received by any Guarantied Party in
respect of any Obligation, and payment to such Guarantied Party of the amount so
refunded shall be fully guaranteed hereby even though prior thereto this
Guaranty shall have been cancelled or surrendered (or any release or termination
of any Collateral by virtue thereof), and such prior cancellation or surrender
shall not diminish, release, discharge, impair or otherwise affect the
obligations of any Guarantor hereunder in respect of the amount so refunded (and
any Collateral so released or terminated shall be reinstated with respect to
such obligations);

even if any right of reimbursement or subrogation or other right or remedy of
any Guarantor is extinguished, affected or impaired by any of the foregoing
(including any election of remedies by reason of any judicial, non-judicial or
other proceeding in respect of the Obligations that impairs any subrogation,
reimbursement or other right of such Guarantor).

      Section 5 Guaranty Absolute and Unconditional

        Each Guarantor hereby waives any defense of a surety or guarantor or any
other obligor on any obligations arising in connection with or in respect of any
of the following and hereby agrees that its obligations under this Guaranty are
absolute and unconditional and shall not be discharged or otherwise affected as
a result of any of the following:

(a)     the invalidity or unenforceability of any of the Borrower’s obligations
under the Credit Agreement or any other Loan Document or any other agreement or
instrument relating thereto, or any security for, or other guaranty of the
Obligations or any part of them, or the lack of perfection or continuing
perfection or failure of priority of any security for the Obligations or any
part of them;

(b)     the absence of any attempt to collect the Obligations or any part of
them from the Borrower or other action to enforce the same;

(c)     failure by any Guarantied Party to take any steps to perfect and
maintain any Lien on, or to preserve any rights to, any Collateral;

the Bankruptcy Code or any applicable provisions of comparable state or foreign
law;

(e)     any borrowing or grant of a Lien by the Borrower, as
debtor-in-possession, or extension of credit, under Section 364 of the
Bankruptcy Code or any applicable provisions of comparable state or foreign law;

(f)     the disallowance, under Section 502 of the Bankruptcy Code or any
applicable provisions of comparable state or foreign law, of all or any portion
of any Guarantied Party’s claim (or claims) for repayment of the Obligations ;

(g)     any use of cash collateral under Section 363 of the Bankruptcy Code or

them for any reason;

(j)     any bankruptcy, insolvency, reorganization, arrangement, readjustment of
debt, liquidation or dissolution proceeding commenced by or against the

any discharge of, or bar or stay against collecting, any Obligation (or any part
of them or interest thereon) in or as a result of any such proceeding;

(k)     failure by any Guarantied Party to file or enforce a claim against the
Borrower or its estate in any bankruptcy or insolvency case or proceeding;

(l)     any action taken by any Guarantied Party if such action is authorized
hereby;

(m)     any election following the occurrence of an Event of Default by any
Guarantied Party to proceed separately against the personal property Collateral
in accordance with such Guarantied Party’s rights under the UCC or, if the
Collateral consists of both personal and real property, to proceed against such
personal and real property in accordance with such Guarantied Party’s rights
with respect to such real property; or

(n)     any other circumstance that might otherwise constitute a legal or
equitable discharge or defense of a surety or guarantor or any other obligor on
any obligations, other than the payment in full in cash of the Obligations.

      Section 6 Waivers

        Each Guarantor hereby waives diligence, promptness, presentment, demand
for payment or performance and protest and notice of protest, notice of
acceptance and any other notice in respect of the Obligations or any part of
them, and any defense arising by reason of any disability or other defense of
the Borrower. Each Guarantor shall not, until the Obligations are irrevocably
paid in full in cash and the Revolving Credit Commitments have been terminated,
assert any claim or counterclaim it may have against the Borrower or set off any
of its obligations to the Borrower against any obligations of the Borrower to
it, other than set offs in connection with the settlement of intercompany
accounts in the ordinary course of business. In connection with the foregoing,
each Guarantor covenants that its obligations hereunder shall not be discharged,
except by complete performance.

      Section 7 Reliance

        Each Guarantor hereby assumes responsibility for keeping itself informed
of the financial condition of the Borrower and any endorser and/or other
guarantor of all or any part of the Obligations, and of all other circumstances
bearing upon the risk of nonpayment of the Obligations, or any part thereof,
that diligent inquiry would reveal, and each Guarantor hereby agrees that no
Guarantied Party shall have any duty to advise any Guarantor of information
known to it regarding such condition or any such circumstances. In the event any
Guarantied Party, in its sole discretion, undertakes at any time or from time to
time to provide any such information to any Guarantor, such Guarantied Party
shall be under no obligation (a) to undertake any investigation not a part of
its regular business routine, (b) to disclose any information that such
Guarantied Party, pursuant to accepted or reasonable commercial finance or
banking practices, wishes to maintain confidential or (c) to make any other or
future disclosures of such information or any other information to any
Guarantor.

      Section 8 Waiver of Subrogation and Contribution Rights

        Until the Obligations have been irrevocably paid in full in cash and the
Revolving Credit Commitments have been terminated, the Guarantors shall not
enforce or otherwise exercise any right of subrogation to any of the rights of
the Guarantied Parties or any part of them against the Borrower or any right of
reimbursement or contribution or similar right against the Borrower by reason of
this Agreement or by any payment made by any Guarantor in respect of the
Obligations.

      Section 9 Subordination

        Each Guarantor hereby agrees that any Indebtedness of the Borrower now
or hereafter owing to any Guarantor, whether heretofore, now or hereafter
created (the “Guarantor Subordinated Debt”), is hereby subordinated to all of
the Obligations and that, except as permitted under Section 8.6 (Prepayment and
Cancellation of Indebtedness) of the Credit Agreement, the Guarantor
Subordinated Debt shall not be paid in whole or in part until the Obligations
have been paid in full in cash and this Guaranty is terminated and of no further
force or effect. No Guarantor shall accept any payment of or on account of any
Guarantor Subordinated Debt at any time in contravention of the foregoing. Upon
the occurrence and during the continuance of an Event of Default, the Borrower
shall pay to the Administrative Agent any payment of all or any part of the
Guarantor Subordinated Debt and any amount so paid to the Administrative Agent
shall be applied to payment of the Obligations as provided in Section 2.12(f)
(Payments and Computations) of the Credit Agreement. Each payment on the
Guarantor Subordinated Debt received in violation of any of the provisions
hereof shall be deemed to have been received by such Guarantor as trustee for
the Guarantied Parties and shall be paid over to the Administrative Agent
immediately on account of the Obligations, but without otherwise affecting in
any manner such Guarantor’s liability hereof. Each Guarantor agrees to file all
claims against the Borrower in any bankruptcy or other proceeding in which the
filing of claims is required by law in respect of any Guarantor Subordinated
Debt, and the Administrative Agent shall be entitled to all of such Guarantor’s
rights thereunder. If for any reason a Guarantor fails to file such claim at
least ten Business Days prior to the last date on which such claim should be
filed, such Guarantor hereby irrevocably appoints the Administrative Agent as
its true and lawful attorney-in-fact and is hereby authorized to act as
attorney-in-fact in such Guarantor’s name to file such claim or, in the
Administrative Agent’s discretion, to assign such claim to and cause proof of
claim to be filed in the name of the Administrative Agent or its nominee. In all
such cases, whether in administration, bankruptcy or otherwise, the person or
persons authorized to pay such claim shall pay to the Administrative Agent the
full amount payable on the claim in the proceeding, and, to the full extent
necessary for that purpose, each Guarantor hereby assigns to the Administrative
Agent all of such Guarantor’s rights to any payments or distributions to which
such Guarantor otherwise would be entitled. If the amount so paid is greater
than such Guarantor’s liability hereunder, the Administrative Agent shall pay
the excess amount to the party entitled thereto. In addition, each Guarantor
hereby irrevocably appoints the Administrative Agent as its attorney-in-fact to
exercise all of such Guarantor’s voting rights in connection with any bankruptcy
proceeding or any plan for the reorganization of the Borrower.

      Section 10 Default; Remedies

        The obligations of each Guarantor hereunder are independent of and
separate from the Obligations. If any Obligation is not paid when due, or upon
any Event of Default hereunder or upon any default by the Borrower as provided
in any other instrument or document evidencing all or any part of the
Obligations, the Administrative Agent may, at its sole election, proceed
directly and at once, without notice, against any Guarantor to collect and
recover the full amount or any portion of the Obligations then due, without
first proceeding against the Borrower or any other guarantor of the Obligations,
or against any Collateral under the Loan Documents or joining the Borrower or
any other guarantor in any proceeding against any Guarantor. At any time after
maturity of the Obligations, the Administrative Agent may (unless the
Obligations have been irrevocably paid in full in cash), without notice to any
Guarantor and regardless of the acceptance of any Collateral for the payment
hereof, appropriate and apply toward the payment of the Obligations (a) any
indebtedness due or to become due from any Guarantied Party to such Guarantor
and (b) any moneys, credits or other property belonging to such Guarantor at any
time held by or coming into the possession of any Guarantied Party or any of its
respective Affiliates.

      Section 11 Irrevocability

        This Guaranty shall be irrevocable as to the Obligations (or any part
thereof) until the Commitments have been terminated and all monetary Obligations
then outstanding have been irrevocably repaid in cash, at which time this
Guaranty shall automatically be cancelled. Upon such cancellation and at the
written request of any Guarantor or its successors or assigns, and at the cost
and expense of such Guarantor or its successors or assigns, the Administrative
Agent shall execute in a timely manner a satisfaction of this Guaranty and such
instruments, documents or agreements as are necessary or desirable to evidence
the termination of this Guaranty.

      Section 12 Setoff

        Upon the occurrence and during the continuance of an Event of Default,
each Guarantied Party and each Affiliate of a Guarantied Party may, without
notice to any Guarantor and regardless of the acceptance of any security or
collateral for the payment hereof, appropriate and apply toward the payment of
all or any part of the Obligations (a) any indebtedness due or to become due
from such Guarantied Party or Affiliate to such Guarantor and (b) any moneys,
credits or other property belonging to such Guarantor, at any time held by, or
coming into, the possession of such Guarantied Party or Affiliate.

      Section 13 No Marshalling

        Each Guarantor consents and agrees that no Guarantied Party or Person
acting for or on behalf of any Guarantied Party shall be under any obligation to
marshal any assets in favor of any Guarantor or against or in payment of any or
all of the Obligations.

      Section 14 Enforcement; Amendments; Waivers

        No delay on the part of any Guarantied Party in the exercise of any
right or remedy arising under this Guaranty, the Credit Agreement, any other
Loan Document or otherwise with respect to all or any part of the Obligations,
the Collateral or any other guaranty of or security for all or any part of the
Obligations shall operate as a waiver thereof, and no single or partial exercise
by any such Person of any such right or remedy shall preclude any further
exercise thereof. No modification or waiver of any provision of this Guaranty
shall be binding upon any Guarantied Party, except as expressly set forth in a
writing duly signed and delivered by the party making such modification or
waiver. Failure by any Guarantied Party at any time or times hereafter to
require strict performance by the Borrower, any Guarantor, any other guarantor
of all or any part of the Obligations or any other Person of any provision,
warranty, term or condition contained in any Loan Document now or at any time
hereafter executed by any such Persons and delivered to any Guarantied Party
shall not waive, affect or diminish any right of any Guarantied Party at any
time or times hereafter to demand strict performance thereof and such right
shall not be deemed to have been waived by any act or knowledge of any
Guarantied Party, or its respective agents, officers or employees, unless such
waiver is contained in an instrument in writing, directed and delivered to the
Borrower or such Guarantor, as applicable, specifying such waiver, and is signed
by the party or parties necessary to give such waiver under the Credit
Agreement. No waiver of any Event of Default by any Guarantied Party shall
operate as a waiver of any other Event of Default or the same Event of Default
on a future occasion, and no action by any Guarantied Party permitted hereunder
shall in any way affect or impair any Guarantied Party’s rights and remedies or
the obligations of any Guarantor under this Guaranty. Any determination by a
court of competent jurisdiction of the amount of any principal or interest owing
by the Borrower to a Guarantied Party shall be conclusive and binding on each
Guarantor irrespective of whether such Guarantor was a party to the suit or
action in which such determination was made.

      Section 15 Successors and Assigns

        This Guaranty shall be binding upon each Guarantor and upon the
successors and assigns of such Guarantors and shall inure to the benefit of the
Guarantied Parties and their respective successors and assigns; all references
herein to the Borrower and to the Guarantors shall be deemed to include their
respective successors and assigns. The successors and assigns of the Guarantors
and the Borrower shall include, without limitation, their respective receivers,
trustees and debtors-in-possession. All references to the singular shall be
deemed to include the plural where the context so requires.

      Section 16 Representations and Warranties; Covenants

        Each Guarantor hereby (a) represents and warrants that the
representations and warranties as to it made by the Borrower in Article IV
(Representations and Warranties) of the Credit Agreement are true and correct on
each date as required by Section 3.2(b)(i) (Conditions Precedent to Each Loan
and Letter of Credit) of the Credit Agreement and (b) agrees to take, or refrain
from taking, as the case may be, each action necessary to be taken or not taken,
as the case may be, so that no Default or Event of Default is caused by the
failure to take such action or to refrain from taking such action by such
Guarantor.

      Section 17 Governing Law

        This Guaranty and the rights and obligations of the parties hereto shall
be governed by, and construed and interpreted in accordance with, the law of the
State of New York.

      Section 18 Submission to Jurisdiction; Service of Process

(a)     Any legal action or proceeding with respect to this Guaranty, and any
other Loan Document, may be brought in the courts of the State of New York or of
the United States of America for the Southern District of New York, and, by
execution and delivery of this Agreement, each Guarantor hereby accepts for
itself and in respect of its property, generally and unconditionally, the
jurisdiction of the aforesaid courts. The parties hereto hereby irrevocably
waive any objection, including any objection to the laying of venue or based on
the grounds of forum non conveniens, that any of them may now or hereafter have
to the bringing of any such action or proceeding in such respective
jurisdictions.

(b)     In the case of any suit, action or proceeding brought in the United
States of America arising out of, or in connection with, this Guaranty or any
other Loan Document, each Guarantor irrevocably consents to the service of any
and all process in any such action or proceeding by the mailing (by registered
or certified mail, postage prepaid) of copies of such process to such Guarantor
in care of the Borrower at the Borrower’s address specified in Section 11.8
(Notices, Etc.) of the Credit Agreement or at such other address as the Borrower
may specify pursuant to such Section 11.8. Each Guarantor agrees that a final
judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law.

(c)     Nothing contained in this Section 18 (Submission to Jurisdiction;
Service of Process) shall affect the right of the Administrative Agent or any
other Guarantied Party to serve process in any other manner permitted by law or
commence legal proceedings or otherwise proceed against a Guarantor in any other
jurisdiction.

(d)     If for the purposes of obtaining judgment in any court it is necessary
to convert a sum due hereunder in Dollars into another currency, the parties
hereto agree, to the fullest extent they may effectively do so, that the rate of
exchange used shall be that at which in accordance with normal banking
procedures the Administrative Agent could purchase Dollars with such other
currency at the spot rate of exchange quoted by the Administrative Agent at
11:00 a.m. (New York time) on the Business Day preceding that on which final
judgment is given, for the purchase of Dollars, for delivery two Business Days
thereafter.

      Section 19 Section Waiver of Judicial Bond

        To the fullest extent permitted by applicable law, the Guarantor waives
the requirement to post any bond that otherwise may be required of any
Guarantied Party in connection with any judicial proceeding to enforce such
Guarantied Party’s rights to payment hereunder, security interest in or other
rights to the Collateral or in connection with any other legal or equitable
action or proceeding arising out of, in connection with, or related to this
Guaranty or any other Loan Documents to which it is a party.

      Section 20 Certain Terms

        The following rules of interpretation shall apply to this Guaranty:

invalidity without invalidating the remainder of such provision or the remaining
provisions of this Guaranty.

Subsidiary to become a Guarantor hereunder, such Subsidiary shall execute and
deliver to the Administrative Agent a Guaranty Supplement in substantially the
