Ladies and Gentlemen:

          You have advised The Chase Manhattan Bank ("Chase") and Chase
Securities Inc. ("CSI") that Mohawk Corp. ("Mohawk") is seeking to acquire PSC
Inc. (the "Target") through a cash tender offer for all of the outstanding
shares of common stock, series A convertible preferred stock and warrants of the
Target (the "Tender Offer").  We understand that the Tender Offer will be
consummated by Mohawk Acquisition Corp., a subsidiary of Mohawk that has been
established for the purpose of making the Tender Offer ("Acquisition Corp."),
and that the Tender Offer will be followed by a merger between Acquisition Corp.
and the Target (the Tender Offer and such merger being collectively referred to
as the "Acquisition"), with the


                                       2



result that the Target will be a wholly owned direct subsidiary of Mohawk. In
addition, prior to or concurrently with the consummation of such merger, Welch
Allyn Data Collection, Inc. ("WADC" and, together with Mohawk and Acquisition
Corp., the "Mohawk Entities" or sometimes collectively hereinafter referred to
as "you") will become a wholly owned direct subsidiary of Mohawk. The price at
which the shares of common and preferred stock of the Target will be acquired
pursuant to the Tender Offer and the Merger will not exceed $8.45 per underlying
common share. You have advised us that the Acquisition has been approved by the
boards of directors of each of the Mohawk Entities and the Target, and such
approval has not been withdrawn or qualified in any manner adverse to the Mohawk
Entities. We understand that the total financing requirements consist of an
aggregate amount up to $305,100,000 for the Acquisition (including the fees and
expenses payable by the Mohawk Entities relating thereto), and an amount
sufficient for the refinancing of certain existing indebtedness of WADC and its
subsidiaries and, after giving effect to the Acquisition, the Target and its
subsidiaries, as shown on Schedule 1 to the Term Sheet referred to below. In
addition, you have advised us that additional financing for working capital
needs and other general corporate purposes is required for WADC, the Target and
their respective subsidiaries, after giving effect to the Acquisition. In
connection with all of the foregoing, you have requested that CSI agree to
structure, arrange and syndicate senior secured credit facilities in an
aggregate amount of up to $225,000,000 (the "Credit Facilities") and that Chase
commit to provide the entire principal amount of the Credit Facilities and to
serve as administrative agent for the Credit Facilities. The transactions
described in this paragraph, including the Acquisition and the Merger and the
financing thereof, are collectively referred to herein as the "Transactions".

          CSI is pleased to advise you that it is willing to act as exclusive
advisor, lead arranger and book manager for the Credit Facilities.

          Furthermore, Chase is pleased to advise you of its commitment to
provide the entire amount of the Credit Facilities upon the terms and subject to
the conditions set forth or referred to in this commitment letter (the
"Commitment Letter"), in the Summary of Terms and Conditions attached hereto as
Exhibit A (the "Term Sheet") and in the Fee Letter dated the date hereof and
delivered herewith (the "Fee Letter").  We intend to syndicate the Credit
Facilities to a group of financial institutions identified by us in consultation
with you (together with Chase, the "Lenders").  Chase shall be relieved of its
obligation to provide the entire amount of the Credit Facilities to the extent
that the offers of Lenders other than Chase to provide any portion of the Credit
Facilities are accepted.

          It is agreed that Chase will act as the sole and exclusive
Administrative Agent, and that CSI will act as the sole and exclusive advisor,
arranger and book manager, for the Credit Facilities, and each will, in such
capacities, perform the duties and exercise the authority customarily performed
and exercised by it in such roles.  You agree that, except as expressly
contemplated by the Term Sheet and the Fee Letter, no other agents, co-agents,
arrangers or book managers will be appointed, no other titles will be awarded
and no compensation will be paid in connection with the Credit Facilities unless
you and we shall so agree.

          CSI intends to commence syndication efforts promptly upon the
execution of this Commitment Letter, and you agree actively to assist CSI in
completing a syndication satisfactory to it.  Such assistance shall include (a)
your using commercially reasonable efforts to ensure that the syndication
efforts benefit materially from your existing lending relationships, (b) direct
contact between senior management and advisors of the Mohawk Entities and the
Target and the


                                       3

proposed Lenders, (c) assistance in the preparation of a Confidential
Information Memorandum and other marketing materials to be used in connection
with the syndication and (d) the hosting, with CSI, of one or more meetings of
prospective Lenders.

          CSI will manage all aspects of the syndication in consultation with
you, including decisions as to the selection of institutions to be approached
and when they will be approached, when their commitments will be accepted, which
institutions will participate, the allocations of the commitments among the
Lenders and the amount and distribution of fees among the Lenders.  To assist
CSI in its syndication efforts, you agree promptly to prepare and provide to CSI
and Chase all information with respect to the Mohawk Entities and their
respective subsidiaries, the Target and its subsidiaries and the Transactions,
including all financial information and projections (the "Projections"), as we
may reasonably request in connection with the arrangement and syndication of the
Credit Facilities.  You hereby represent and covenant that (a) all information
(other than the Projections) (the "Information"), taken as a whole, that has
been or will be made available to Chase or CSI by you or any of your
representatives is or will be, when furnished, complete and correct in all
material respects and does not or will not, when furnished, contain any untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements (taken as a whole) contained therein not materially
misleading in light of the circumstances under which such statements are made
and (b) the Projections that have been or will be made available to Chase or CSI
by you or any of your representatives have been or will be prepared in good
faith based upon reasonable assumptions at the time of preparation and at the
time made available to Chase or CSI.  You agree that if, at any time from and
including the date hereof until the closing of the Credit Facilities, any of the
representations in the preceding sentence would be incorrect if the Information
and Projections were being furnished, and such representations were being made,
at such time, then you will promptly supplement the Information and the
Projections so that such representations will be correct under those
circumstances.  In arranging and syndicating the Credit Facilities, Chase and
CSI will be entitled to use and rely primarily on the Information and the
Projections without responsibility for independent verification thereof.

          As consideration for Chase's commitment hereunder and CSI's agreement
to perform the services described herein, you agree, jointly and severally, to
pay to Chase the non-refundable fees set forth in the Term Sheet and in the Fee
Letter.

          Chase's commitment hereunder and CSI's agreement to perform the
services described herein are subject to (a) there not occurring or becoming
known to us any material adverse condition or material adverse change in or
affecting the business, operations, property, condition (financial or otherwise)
or prospects of WADC and its subsidiaries, taken as a whole, or the Target and
its subsidiaries, taken as a whole, in each case since December 31, 1999, (b)
our not becoming aware after the date hereof of any information or other matter
affecting WADC and its subsidiaries, the Target and its subsidiaries or the
Transactions that, in our judgment, is inconsistent in a material and adverse
manner with any such information or other matter disclosed to us prior to the
date hereof, (c) there not having occurred a material disruption of or material
adverse change in financial, banking or capital market conditions that, in our
judgment, could materially impair the syndication of the Credit Facilities, (d)
our satisfaction that prior to and during the syndication of the Credit
Facilities there shall be no competing offering, placement or arrangement of any
debt securities or bank financing by or on behalf of the Mohawk Entities or any
of their respective subsidiaries, (e) the negotiation, execution and delivery on
or before August 31, 2000 of definitive documentation with respect to the Credit


                                       4

Facilities satisfactory to Chase and its counsel, (f) Chase's satisfaction in
all material respects with the structure of the Acquisition and the other
Transactions and all tax, legal, ERISA, environmental and accounting matters
related thereto, (g) delivery to Chase of, and Chase's satisfaction with, (i)
the unaudited interim consolidated financial statements of each of WADC and the
Target for each fiscal month after the most recent 2000 fiscal quarter for which
financial statements are available and ended at least 30 days before the Closing
Date and (ii) projections of Mohawk and its subsidiaries (including WADC, the
Target and their respective subsidiaries) for fiscal years 2000-2006 together
with related assumptions, (h) CSI's having been afforded a reasonable period
following the date hereof to syndicate the Credit Facilities and (i) the other
conditions set forth herein or referred to in the Term Sheet.  The terms and
conditions of Chase's commitment hereunder and of the Credit Facilities are not
limited to those set forth herein and in the Term Sheet.  Those matters that are
not covered by the provisions hereof and of the Term Sheet are subject to the
approval and agreement of Chase, CSI and the Mohawk Entities.

          You agree, jointly and severally, (a) to indemnify and hold harmless
Chase, CSI, their affiliates and their respective officers, directors,
employees, advisors, and agents (each, an "indemnified person") from and against
any and all losses, claims, damages and liabilities to which any such
indemnified person may become subject arising out of or in connection with this
Commitment Letter, the Credit Facilities, the use of the proceeds thereof, the
Transactions or any related transaction or any claim, litigation, investigation
or proceeding relating to any of the foregoing, regardless of whether any
indemnified person is a party thereto, and to reimburse each indemnified person
upon demand for any legal or other expenses incurred in connection with
investigating or defending any of the foregoing, provided that the foregoing
                                                 --------
indemnity will not, as to any indemnified person, apply to losses, claims,
damages, liabilities or related expenses to the extent they are found by a
final, non-appealable judgment of a court to arise from the willful misconduct
or gross negligence of such indemnified person, and (b) to reimburse Chase, CSI
and their affiliates on demand for all reasonable out-of-pocket expenses
(including due diligence expenses, syndication expenses, consultant's fees and
expenses, travel expenses, and reasonable fees, charges and disbursements of
counsel) incurred in connection with the Credit Facilities and any related
documentation (including this Commitment Letter, the Term Sheet, the Fee Letter
and the definitive financing documentation) or the administration, amendment,
modification or waiver thereof.  No indemnified person shall be liable for any
damages arising from the use by unintended recipients of Information or other
materials distributed through electronic, telecommunications or other
information transmission systems (but excluding any such damages to the extent
they are found by a final, non-appealable judgment of a court to arise from the
willful misconduct or gross negligence of such indemnified person), or for any
special, indirect, consequential or punitive damages in connection with the
Credit Facilities.

          You acknowledge that Chase and/or CSI may be providing debt financing,
equity capital or other services (including financial advisory services) to
other companies in respect of which you may have conflicting interests regarding
the Transactions and otherwise.  Neither Chase nor CSI will use confidential
information obtained from you by virtue of the Transactions or other
relationships with you in connection with the performance by Chase or CSI of
services for other companies, and neither Chase nor CSI will furnish any such
information to other companies.  You also acknowledge that neither Chase nor CSI
has any obligation to use in connection with the Transactions, or to furnish to
you, confidential information obtained by Chase or CSI or any of their
respective affiliates from other companies.

                           Interest and Certain Fees
                           -------------------------


 Interest Rate Options:  The Borrower may elect that the Loans comprising
                         each borrowing bear interest at a rate per annum equal
                         to:

                            the ABR plus the Applicable Margin; or
                                    ----

                            the Eurodollar Rate plus the Applicable Margin.
                                                ----

                         As used herein:

                         "ABR" means the higher of (i) the rate of interest

                         time to time plus 0.5%.
                                      ----

                         "Applicable Margin" means (i) initially for 90 days,
                         2.25% per annum in the case of Eurodollar Loans (as
                         defined below) and (ii) thereafter, a percentage
                         determined in accordance with the Pricing Grid attached
                         hereto as Annex I-A (the "Pricing Grid").

                         "Eurodollar Rate" means the rate (adjusted for
                         statutory reserve requirements for eurocurrency

                         three or six months (as selected by the Borrower) are
                         quoted on the Telerate Service.  Statutory reserve

                         Eurodollar Rate ("Eurodollar Loans"), on the last day
                         of each relevant interest period and, in the case of
                         any interest period longer than three months, on each
                         successive date three months after the first day of
                         such interest period.

     Commitment Fees:    The Borrower shall pay a commitment fee calculated at a
                         per annum percentage determined in accordance with the
                         Pricing Grid on the average daily unused portion of the

 Letter of Credit Fees:  The Borrower shall pay a commission on all
                         outstanding Letters of Credit at a per annum rate equal

                         of each such Letter of Credit. Such commission shall be
                         shared ratably among the Lenders participating in the
                         Revolving Facility and shall be payable quarterly in
                         arrears.

                         on the face amount of each Letter of Credit shall be
                         payable quarterly in arrears to the Issuing Lender for
                         its own account.  In addition, customary
                         administrative, issuance, amendment, payment and

                         Facilities, such amount shall bear interest at 2% above
                         the rate otherwise applicable thereto. Overdue
                         interest, fees and other amounts shall bear interest at
                         2% above the rate applicable to ABR Loans.

    Rate and Fee Basis:  All per annum rates shall be calculated on the basis
                         of a year of 360 days (or 365/366 days, in the case of
                         ABR Loans the interest rate payable on which is then
                         based on the Prime Rate) for actual days elapsed.
