                  SUBSCRIPTION CERTIFICATE FOR RIGHTS OFFERING
                  FOR HOLDERS OF RECORD ON [____________], 2006

         DEL GLOBAL TECHNOLOGIES CORP. (the "Company") is conducting a rights
offering (the "Rights Offering") that entitles the holders of the Company's
common stock, $0.10 par value per share (the "Common Stock"), as of the close of
business on [________], 2006 (the "Record Date") to receive one non-transferable
subscription right (each, a "Right") for each share of Common Stock held of
record on the Record Date. Each Right entitles the holder to subscribe for and
purchase one share of Common Stock at a subscription price of $[____] per share
(the "Basic Subscription Right"). Set forth above is the number of shares to
which the holder whose name and address is set forth above is entitled to
subscribe pursuant to the Basic Subscription Right. If you exercise all of your
Basic Subscription Rights in full, you may also exercise an over-subscription
right (the "Over-Subscription Right") to purchase additional shares of Common
Stock that remain unsubscribed at the expiration of the Rights Offering, subject
to availability and allocation of shares among persons exercising this
Over-Subscription Right. If there is a change of address and you wish to
subscribe, please note the new address and notify Mellon Investor Services LLC,
the subscription agent, at the address listed in the Prospectus (as defined
below) under the heading "The Rights Offering--Delivery of Subscription
Materials and Payment."

         FOR A MORE COMPLETE DESCRIPTION OF THE TERMS AND CONDITIONS OF THE
RIGHTS OFFERING, PLEASE REFER TO THE COMPANY'S PROSPECTUS DATED [_________],
2006 (THE "PROSPECTUS"), WHICH IS INCORPORATED HEREIN BY REFERENCE. COPIES OF
THE PROSPECTUS ARE AVAILABLE UPON REQUEST FROM THE COMPANY AT (847) 288-7000.

         THIS SUBSCRIPTION CERTIFICATE (THE "RIGHTS CERTIFICATE") MUST BE
RECEIVED BY MELLON INVESTOR SERVICES LLC, THE SUBSCRIPTION AGENT, WITH PAYMENT
IN FULL BY 5:00 P.M., NEW YORK CITY TIME, ON [_________], 2006, SUBJECT TO
EXTENSION (THE "EXPIRATION DATE"). ANY RIGHTS NOT EXERCISED PRIOR TO THE
EXPIRATION DATE WILL EXPIRE AND WILL HAVE NO VALUE. ANY SUBSCRIPTION FOR SHARES
OF COMMON STOCK IN THE RIGHTS OFFERING MADE HEREBY IS IRREVOCABLE.

         The Rights represented by this Rights Certificate may be exercised by
duly completing Form 1. Rights holders are advised to review the Prospectus and
instructions, copies of which are available from the Company before exercising
their Rights. In addition, if certificates representing the Common Stock are to
be issued in a name other than the registered holder or are to be sent to an
address other than that shown above, also complete Form 2.

         SUBSCRIPTION PRICE: $[____] PER SHARE




         The registered owner whose name is inscribed hereon is entitled to
subscribe for shares of Common Stock upon the terms and subject to the
conditions set forth in the Prospectus and instructions relating to the use
hereof.

         Except in limited circumstances described in the Prospectus, only you
may exercise your Rights.

         RIGHTS HOLDERS SHOULD BE AWARE THAT IF THEY CHOOSE TO EXERCISE ONLY
PART OF THEIR RIGHTS, THEY MAY NOT RECEIVE A NEW RIGHTS CERTIFICATE IN
SUFFICIENT TIME TO EXERCISE THE REMAINING RIGHTS EVIDENCED THEREBY.

         The Company's ability to utilize its NOLs against future taxable
income, if any, would be substantially reduced if it were to undergo an
ownership change within the meaning of Section 382 of the Internal Revenue Code.
Section 382 generally restricts the use of an NOL after an "ownership change" to
an annual amount equal to the value of the company multiplied by a government
interest rate. An "ownership change" is generally a more than 50 percentage
point increase in stock ownership measured by value, during a 3-year testing
period by "5% shareholders". In determining 5% ownership, the following
attribution provisions apply for purposes of Section 382 of the Code:

         o     Any family group consisting of an individual, spouse, children,
               grandchildren and parents are treated as one person. Note that an
               individual can be treated as a member of several different family
               groups. For example, your family group would include your spouse,
               children, father and mother, but your mother's family group would
               include her spouse, all her children and her grandchildren.

         o     Any common stock owned by any entity will generally be attributed
               proportionately to the ultimate owners of that entity.
               Attribution will also occur through tiered entity structures.

         o     Any persons or entities acting in concert or having a formal or
               informal understanding among themselves to make a coordinated
               purchase of common stock will be treated as one stockholder.

         o     Ownership may not be structured with an abusive principal purpose
               of avoiding these rules.

         The Company has the right, in its sole and absolute discretion, to
limit the exercise of rights, including instructing the subscription agent to
refuse to honor any exercise of rights, by 5% shareholders or a subscriber to
the extent its exercise of rights might, in the Company's sole and absolute
discretion, result in a subscriber owning 5% or more of the Company's common
stock.

         IN ORDER TO PROTECT AGAINST AN UNEXPECTED "OWNERSHIP CHANGE" FOR
FEDERAL INCOME TAX PURPOSES, THE COMPANY HAS IMPLEMENTED THE PROTECTION
MECHANICS AS FOLLOWS:



         o     by purchasing shares of common stock, each subscriber will
               represent to us that it will not be, after giving effect to the
               purchase of the common stock, an owner, either direct or
               indirect, record or beneficial, or by application of Section 382
               attribution provisions summarized above, of more than 1.2 million
               shares of the Company's common stock;

         o     if an exercise would result in the subscriber owning more than
               1.2 million shares of the Company's common stock, the subscriber
               must notify the subscription agent at the telephone number set
               forth under the heading "Subscription Agent;"

         o     if requested, each subscriber will be required to provide us with
               additional information regarding the amount of common stock that
               the subscriber owns; and

         o     the Company has the right to instruct the subscription agent to
               refuse to honor a subscriber's exercise to the extent an exercise
               might, in the Company's sole and absolute discretion, result in
               the subscriber owning 5% or more of the Company's common stock.

         By exercising rights in the offering, you agree that:

         o     the protection mechanics are valid, binding and enforceable
               against you;

         o     any purported exercise of rights, in violation of the protection
               mechanics section, will be void and of no force and effect; and

         o     the Company has the right to void and cancel (and treat as if
               never exercised) any exercise of rights, and shares issued
               pursuant to an exercise of rights, if any of the agreements,
               representations or warranties of a subscriber in the subscription
               documents are false.

subscriber without interest or deduction as soon as practicable.
