has, during the past five years, been convicted in any criminal proceeding
(excluding traffic violations or similar misdemeanors).

         (e) None of the Reporting Persons or, to the best knowledge and belief

                               Page 5 of 18 Pages


ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         Pursuant to the Asset Purchase Agreement, dated as of November 17,
2000, between KPENV and Agilent Technologies, Inc., a Delaware corporation
("Agilent"), on August 1, 2001, PENAC acquired, as part of KPENV's acquisition
of Agilent's healthcare solutions assets, 1,357,143 Shares and a warrant to
purchase from Diametrics 452,381 Shares at a price per Share of $8.40 (the
"Warrant"), which Warrant expires on August 4, 2003. KPENV paid Agilent
approximately $1.7 billion for such healthcare solutions assets, and a separate
price for the Shares and/or the Warrant was not specified or agreed.

         There have been no transactions by the Reporting Persons in securities
of Diametrics in the last 60 days.

         None of the persons listed on Schedules I, II or III hereto has
contributed any funds or other consideration towards the purchase of the Shares
reported in this statement.

ITEM 4.  PURPOSE OF THE TRANSACTION.

         Other than as set forth herein, none of the Reporting Persons, or to
the best knowledge and belief of the Reporting Persons, any of the individuals
listed on Schedules I, II or III hereto has plans or proposals which relate to
or would result in any of the events described by Items 4(a) through 4(j) of
Schedule 13D. Each Reporting Person expects to evaluate on an ongoing basis
Diametrics' financial condition, business operations and prospects, market price
of the Shares, conditions in securities markets generally, general economic and
industry conditions and other factors. Accordingly, each Reporting Person
reserves the right to change its plans and intentions at any time, as it deems
appropriate. In particular, each Reporting Person may at any time and from time
to time acquire additional Shares or securities convertible or exchangeable for
Shares; may dispose of Shares; and/or may enter into privately negotiated
derivative transactions with institutional counterparties to hedge the market
risk of some or all of its positions in such Shares. Any such transactions may
be effected at any time and from time to time be subject to any applicable
limitations of the Securities Act of 1933. To the knowledge of each Reporting
Person, each of the persons listed on Schedules I, II or III hereto may make the
same evaluation and reserves the same rights.

         On April 10, 2003, Diametrics and Philips Medical Systems North America
Company ("Philips Medical Systems"), a division of PENAC, entered into an
Amendment to Manufacturing and Distribution Agreement (the "New Distribution
Agreement"), pursuant to which (i) Diametrics appointed Philips Medical Systems
as a nonexclusive distributor of specified Diametrics products; (ii) Philips
Medical Systems agreed to refer to Diametrics any orders for specified
Diametrics products that Philips Medical Systems receives from its existing
distributors of such products outside North America; and (iii) Diametrics has
the nonexclusive right to purchase the Portal Product (as defined therein) from
Philips Medical Systems, in each case on specified terms. Concurrently,
Diametrics and Philips Medical Systems entered into a Portal Manufacturing
Agreement, pursuant to which Diametrics agreed to manufacture certain Portal
Products exclusively for Philips Medical Systems on specified terms.

         The foregoing paragraph is qualified in its entirety by reference to
the New Distribution Agreement and to the Portal Manufacturing Agreement, each
of which are incorporated herein by reference.

March 31, 2003 (the "Outstanding Shares").

Shares issuable upon full exercise of the Warrant, which figure represents
approximately 6.66% of the Outstanding Shares.

         PHUSA may be deemed to beneficially own 1,809,524 Shares, including

Shares issuable upon full exercise of the Warrant, which figure represents

         None of the Reporting Persons or, to the best knowledge and belief of
the Reporting Persons, any of the persons listed on Schedules I, II or III
hereto beneficially owns any Shares other than as set forth herein.

         (b) Each Reporting Person has the power to vote or direct the vote and

         TO SECURITIES OF THE ISSUER.

         There are no contracts, arrangements, understandings or relationships

best knowledge and belief of the Reporting Persons, none of the persons listed
on Schedules I, II or III hereto, and other persons with respect to the Shares.
