(1) Based upon the assumed maximum number of shares that may be issued in the
    Merger described herein.
(2) Estimated solely for the purpose of computing the registration fee in
    accordance with Rule 457(f). Pursuant to Rule 457(f)(1), the maximum
    offering price per share is the product of the estimated maximum number of
    shares of Pulse Common Stock expected to be exchanged for Technitrol
    Common Stock in the Merger (1,794,969 ) times the average of the high and
    low prices of the Common Stock in the consolidated reporting system on
    August 16, 1995 ($8.875 ) divided by the number of shares of Registrant's
    common stock registered hereby. The maximum aggregate offering price is
    such maximum offering price per share multiplied by the number of shares
    of Registrant's common stock registered hereby. The Registrant previously
    paid $5,764.17 based on the high and low prices of its Common Stock on
    June 26, 1995, when the Registrant initially filed preliminary proxy
    materials. The fee is reduced by such amount pursuant to Rule 457(b).
 
  THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT
SHALL FILE A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS
REGISTRATION STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH
SECTION 8(A) OF THE SECURITIES ACT OF 1933 OR UNTIL THE REGISTRATION STATEMENT
SHALL BECOME EFFECTIVE ON SUCH DATE AS THE SECURITIES AND EXCHANGE COMMISSION,
ACTING PURSUANT TO SAID SECTION 8(A), MAY DETERMINE.

Dear Shareholder:
 
  A Special Meeting of Shareholders of Technitrol, Inc. ("Technitrol"), will
be held on Wednesday, September 27, 1995 at 11:00 a.m., local time, at the
Bucks County Holiday Inn, 4700 Street Road, Trevose, Pennsylvania 19053.
 
  At the Special Meeting, you will be asked to consider and vote upon the
approval and adoption of (i) an Agreement and Plan of Merger, dated May 23,
1995 (the "Merger Agreement"), by and among Technitrol, its wholly-owned
subsidiary Teco Sub, Inc. ("Sub") and Pulse Engineering, Inc. ("Pulse")
providing for the merger (the "Merger") of Pulse and Sub, as described in the
accompanying Proxy Statement, and (ii) a proposed amendment (the "Charter
Amendment") to Technitrol's Articles of Incorporation to increase the number
of authorized shares of Technitrol Common Stock from 10,000,000 shares to
30,000,000 shares.
 
  Pursuant to the Merger, in which Pulse will become an indirectly wholly-
owned subsidiary of Technitrol, each share of Class A voting common stock of
Pulse ("Pulse Common Stock") will be converted into the right to receive (i)
 .5812 shares (the "Exchange Ratio") of Common Stock of Technitrol ("Technitrol
Common Stock"), (ii) Eight Dollars and Fifty Cents ($8.50) in cash, without
interest, or (iii) a combination of shares of Technitrol Common Stock and cash
determined in accordance with the terms of the Merger Agreement; provided,
however, that the Exchange Ratio may be adjusted (as adjusted, the "Adjusted
Exchange Ratio") based on the average closing price of Technitrol Common Stock
for a specified two week period prior to the Merger. In addition, each then
outstanding option to purchase shares of Pulse Common Stock will be assumed by
Technitrol (the "Assumed Options"). Each Assumed Option will be converted into
an option to purchase a number of shares of Technitrol Common Stock equal to
the number of shares of Pulse Common Stock that were subject to such option
immediately prior to the Merger, multiplied by the Adjusted Exchange Ratio and
the exercise price of each Assumed Option will be adjusted by dividing the
exercise price by the Adjusted Exchange Ratio.
 
  The Charter Amendment is being proposed so that there will be after the
issuance of the shares of Technitrol's Common Stock in conjunction with the
Merger (i) adequate shares of Technitrol Common Stock authorized for issuance
in connection with the continuation of Technitrol's Restricted Stock Plan,
(ii) an adequate number of shares of Technitrol Common Stock available for
exercise of the Assumed Options, and (iii) additional authorized shares of
Technitrol Common Stock available for issuance in the future.
 
  After careful consideration, Technitrol's Board of Directors has unanimously
approved both the Merger Agreement and the Charter Amendment and has
determined that the Merger and the Charter Amendment are in the best interests
of Technitrol and its shareholders. THE BOARD OF DIRECTORS UNANIMOUSLY
RECOMMENDS A VOTE IN FAVOR OF APPROVAL AND ADOPTION OF BOTH THE MERGER
AGREEMENT AND THE CHARTER AMENDMENT.
 
  Accompanying this letter is a Joint Proxy Statement relating to the action
to be taken by Technitrol shareholders at the Special Meeting and action to be
taken by the Pulse stockholders at their special meeting to be held on the
same day as the Technitrol Special Meeting. The Joint Proxy Statement more
fully describes the proposed Merger and Charter Amendment and includes
information about Technitrol and Pulse.
 
  Whether or not you plan to attend the Special Meeting, please complete, sign
and date the accompanying proxy card and return it in the enclosed prepaid
envelope. If you attend the Special Meeting, you may vote in person even if
you have previously returned your proxy card. Your prompt cooperation will be
greatly appreciated.
 
                                          Sincerely,

Dear Stockholder:
 
  A Special Meeting of Stockholders of Pulse Engineering, Inc. will be held on
Wednesday, September 27, 1995 at 8:00 a.m., Pacific Daylight Time, at the
offices of the Company, 12220 World Trade Drive, San Diego, California 92128.
 
  At the Special Meeting, stockholders will be asked to consider and vote upon
the approval and adoption of an Agreement and Plan of Merger, dated May 23,
1995 (the "Merger Agreement"), by and among Pulse, Technitrol, Inc.
("Technitrol") and Technitrol's wholly owned subsidiary, Teco Sub, Inc.
("Sub") providing for the merger of Pulse with and into Sub (the "Merger").
 
  Pursuant to the Merger, in which Pulse will become a wholly owned subsidiary
of Technitrol, each share of Class A Voting Common Stock of Pulse ("Pulse
Common Stock") will be converted into the right to receive (i) shares of
Common Stock of Technitrol ("Technitrol Common Stock") determined pursuant to
an exchange ratio (initially .5812), (ii) Eight Dollars and Fifty Cents
($8.50) in cash, without interest, or (iii) a combination of shares of
Technitrol Common Stock and cash determined in accordance with the terms of
the Merger Agreement. The Exchange Ratio will be adjusted (as adjusted, the
"Adjusted Exchange Ratio") if the average closing price of Technitrol Common
Stock for a specified two-week period prior to the Merger is below $13.75 or
above $16.375.
 
  Stockholders may elect to receive all Technitrol Common Stock or all cash in
exchange for their Pulse Common Stock subject to the limitation that not less
than 50% and not more than 55% of the Pulse Common Stock may be exchanged for
Technitrol Common Stock. Each stockholder has received herewith a Form of
Election. The Form of Election should be returned to Registrar and Transfer
Company in the pre-addressed envelope provided, which is labeled Form of
Election in BLUE. Please review carefully the instructions enclosed with the
Form of Election.
 
  In addition, each then outstanding option to purchase shares of Pulse Common
Stock will be assumed by Technitrol (the "Assumed Options"). Each Assumed
Option will be converted into an option to purchase a number of shares of
Technitrol Common Stock equal to the number of shares of Pulse Common Stock
that were subject to such option immediately prior to the Merger, multiplied
by the Adjusted Exchange Ratio. The exercise price of each Assumed Option will
be adjusted by dividing the exercise price by the Adjusted Exchange Ratio.
 
  The Pulse Board of Directors has unanimously approved the Merger Agreement
and has determined that the Merger is in the best interests of Pulse and its
stockholders. The Board of Directors unanimously recommends a vote in favor of
approval and adoption of the Merger Agreement.
 
  Accompanying this letter is a Prospectus and Joint Proxy Statement dated
August  , 1995 relating to the action to be taken by Pulse stockholders at the
Special Meeting and at a special meeting of the shareholders of Technitrol.
The Prospectus and Joint Proxy Statement more fully describes the proposed
Merger and includes important information about Pulse and Technitrol. You are
urged to review the enclosed Prospectus and Joint Proxy Statement carefully.
 
  Whether or not you plan to attend the Special Meeting, please complete, sign
and date the accompanying proxy card and return it in the enclosed pre-
addressed envelope to First Interstate Bank of California. If you receive more
than one proxy card, please complete, sign, date and return all such proxy
cards so that all of your shares are represented at the Special Meeting. If
you attend the Special Meeting, you may vote in person even if you have
previously returned your proxy card. Your prompt cooperation will be greatly
appreciated.

      PRELIMINARY PROSPECTUS, SUBJECT TO COMPLETION, DATED AUGUST 21, 1995
 
                  TECHNITROL, INC. AND PULSE ENGINEERING, INC.
 
                             JOINT PROXY STATEMENT
 
                                  -----------
 
                                TECHNITROL, INC.
 
                                   PROSPECTUS
 
  This Prospectus and Joint Proxy Statement ("Proxy Statement") is being
furnished to stockholders of Pulse Engineering, Inc. ("Pulse") and to
shareholders of Technitrol, Inc. ("Technitrol") in connection with the
solicitation of proxies by the Boards of Directors of the two companies for use
at their respective special meetings of securityholders to be held on September
27, 1995 to vote upon the proposed merger (the "Merger") of Pulse with and into
a wholly owned subsidiary of Technitrol, pursuant to an Agreement and Plan of
Merger dated May 23, 1995 (the "Merger Agreement"). A copy of the Merger
Agreement is attached to this Proxy Statement as Annex A. As a result of the
Merger, Pulse will become a wholly owned subsidiary of Technitrol.
 
  The Merger Agreement provides for each outstanding share of Class A voting
common stock, par value $.01 per share, of Pulse ("Pulse Common Stock") (except
for shares held by Pulse as treasury shares and shares as to which appraisal
rights have been perfected ("Dissenters' Shares") under the Delaware General
Corporation Law (the "DGCL")) to be converted into the right to receive (i)
 .5812 shares (the "Exchange Ratio") of common stock, $.125 par value per share,
of Technitrol ("Technitrol Common Stock"), (ii) Eight Dollars and Fifty Cents
($8.50) in cash, without interest (the "Per Share Cash Amount"), or (iii) a
combination of shares of Technitrol Common Stock and cash determined in
accordance with the terms of the Merger Agreement; provided, however, that the
Exchange Ratio may be adjusted based on the average closing price (the "Average
Closing Price") of Technitrol Common Stock for a specified two-week period
prior to the Merger. If the Average Closing Price is less than $13 3/4, then
the Exchange Ratio will be increased to that ratio which yields, based upon the
Average Closing Price, $8.00 per share of Pulse Common Stock. If the Average
Closing Price is greater than $16 3/8, then the Exchange Ratio will be reduced
to that ratio which yields, based upon the Average Closing Price, $9.52 per
share of Pulse Common Stock. Such adjustments to the Exchange Ratio are
intended to increase the likelihood that shares of Technitrol Common Stock
delivered to Pulse stockholders will have a current market value of between
$8.00 and $9.52 per share of Pulse Common Stock. A detailed description of the
Merger is set forth in this Proxy Statement. See "THE MERGER AND RELATED
TRANSACTIONS." CERTAIN RISK FACTORS ARE DESCRIBED UNDER THE CAPTION "RISK
FACTORS" AT PAGE 33.
 
  Technitrol has filed a Registration Statement on Form S-4 with the Securities
and Exchange Commission ("SEC") pursuant to the Securities Act of 1933, as
amended (the "Securities Act"), covering the shares of Technitrol Common Stock
to be issued in connection with the Merger (the "Registration Statement"). This
Proxy Statement constitutes (i) the Prospectus of Technitrol filed as part of
the Registration Statement, (ii) the Proxy Statement of Pulse relating to a
Special Meeting of Stockholders of Pulse to consider and vote on approval and
adoption of the Merger Agreement (together with any adjournments or
postponements thereof, the "Pulse Special Meeting"), and (iii) the Proxy
Statement of Technitrol relating to a Special Meeting of Shareholders of
Technitrol to consider and vote on approval and adoption of (A) the Merger
Agreement, and (B) a proposed amendment to Technitrol's Articles of
Incorporation to increase the number of authorized shares of Technitrol Common
Stock from 10 million shares to 30 million shares (together with any
adjournments or postponements thereof, the "Technitrol Special Meeting"). All
information herein with respect to Pulse has been furnished by Pulse, and all
information herein with respect to Technitrol has been furnished by Technitrol.
This Proxy Statement may not be used for resales of securities that will be
issued to persons and parties deemed to be underwriters.
 
  This Proxy Statement, the accompanying forms of proxy and the other enclosed
documents are first being mailed to shareholders of Technitrol and stockholders
of Pulse on or about August  , 1995.
 
NEITHER THE MERGER NOR THE SECURITIES OF TECHNITROL, INC. TO BE ISSUED IN THE
MERGER HAVE BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE
COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY
OR ADEQUACY OF THIS PROXY STATEMENT. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.
 
    The date of this Prospectus and Joint Proxy Statement is August  , 1995.

or by proxy of the holders of a majority of the outstanding shares of Pulse

THE MERGER
 
  Effective Time of the Merger. The Merger will become effective upon the
filing of a certificate of merger with the Secretary of State of the State of
Delaware (the "Effective Time"). It is anticipated that the Effective Time will
be on or about September 29, 1995.
 
  Conversion of Shares of Pulse Common Stock. Upon consummation of the Merger,
Pulse will merge with and into Teco Sub, and Teco Sub will be the surviving
corporation in the Merger (the "Surviving Corporation") and will change its
name to Pulse Engineering, Inc. As a result of the Merger, the Surviving
Corporation will be a wholly owned subsidiary of Technitrol, and each share of
Pulse Common Stock outstanding immediately prior to the Effective Time (other
than shares held by Pulse as treasury shares or Dissenters' Shares) will be
converted into the right to receive (i) shares of Technitrol Common Stock
determined pursuant to the Exchange Ratio (.5812 shares prior to adjustment, if
any), (ii) the Per Share Cash Amount (i.e., Eight Dollars and Fifty Cents
($8.50)), without interest, or (iii) a combination of shares of Technitrol
Common Stock and cash determined in accordance with the Merger Agreement;
provided, however, that the Exchange Ratio may be adjusted based upon the
average closing price (the "Average Closing Price") of Technitrol Common Stock
on the ASE as reported in The Wall Street Journal for the ten (10) trading days
immediately preceding the three (3) business days preceding the Effective Time
(the Exchange Ratio, as adjusted, is hereinafter referred to as the "Adjusted
Exchange Ratio"). See "TERMS OF THE MERGER--Conversion of Shares of Pulse
Common Stock; Election." Fractional shares of Technitrol Common Stock will not
be issued in connection with the Merger. A holder of Pulse Common Stock
otherwise entitled to a fractional share will be paid cash in lieu of such
fractional shares.
 
  Election; Form of Election Procedures. Subject to the allocation procedures
set forth below, each record holder of shares of Pulse Common Stock will be
entitled (i) to elect to receive cash for all of such shares (a "Cash
Election"), (ii) to elect to receive Technitrol Common Stock for all of such
shares (a "Stock Election"), or (iii) to indicate that such holder has no
preference as to the receipt of cash or Technitrol Common Stock for such shares
(a "Non-Election"). All such elections are to be made on a form of election
(the "Form of Election"). Holders of record of shares of Pulse Common Stock who
hold such shares as nominees, trustees or in other representative capacities (a
"Representative") may submit multiple Forms of Election, provided that any such
Representative certifies that each such Form of Election covers all the shares
of Pulse Common Stock held by such Representative for a particular beneficial
owner. All elections will be revocable until 5:00 p.m. New York City time on
the last business day prior to the Effective Time. A Non-Election shall be
deemed to have been made by shares as to which a valid and timely Form of
Election is not received.
 
                                       6
<PAGE>
 
 
  If the aggregate number of shares of Pulse Common Stock as to which valid
elections to receive cash have been made (the "Cash Election Shares") exceeds
fifty percent (50%) of the shares of Pulse Common Stock outstanding immediately
prior to the Effective Time (the "Cash Election Number"), all shares of Pulse
Common Stock covered by Stock Elections (the "Stock Election Shares") and all
shares of Pulse Common Stock covered by Non-Elections (the "Non-Election
Shares") shall be converted into the right to receive Technitrol Common Stock,
and the Cash Election Shares shall be converted into the right to receive
Technitrol Common Stock and cash in the following manner:
 
  each Cash Election Share shall be converted into the right to
  receive (i) an amount in cash, without interest, equal to the
  product of (x) the Per Share Cash Amount and (y) a fraction (the
  "Cash Fraction"), the numerator of which shall be the Cash Election
  Number and the denominator of which shall be the total number of
  Cash Election Shares, and (ii) a number of shares of Technitrol
  Common Stock equal to the product of (x) the Exchange Ratio and (y)
  a fraction equal to one minus the Cash Fraction.
 
  For example, if 75% of the outstanding shares of Pulse Common Stock
  elect cash, then all holders of Stock Election Shares and Non-
  Election Shares would receive Technitrol Common Stock in exchange
  for their shares of Pulse Common Stock based on the Adjusted
  Exchange Ratio. The Cash Election Shares would be exchanged for a
  combination of Technitrol Common Stock and cash based upon a Cash
  Fraction determined by dividing the Cash Election Number (50%) by
  the Cash Election Shares (75%) or two-thirds ( 2/3). Accordingly, a
  hypothetical Pulse stockholder holding 1,000 shares for which a Cash
  Election is made would be entitled to receive the following
  (assuming the Adjusted Exchange Ratio is .5812):
 
   (1) $5,666.67 in cash (the product of (i) the Per Share Cash
       Amount of $8.50, (ii) the Cash Fraction ( 2/3) and (iii) the
       number of shares at issue (1,000)); and
 
   (2) 193.73 shares of Technitrol Common Stock (the product of (i)
       the Exchange Ratio of .5812, (ii) a fraction equal to one
       minus the Cash Fraction ( 1/3) and (iii) the number of shares
       at issue (1,000)), except that the stockholder would actually
       receive 193 shares and cash in lieu of the fractional share.
 
  If the aggregate number of Stock Election Shares exceeds fifty-five percent
(55%) of the shares of Pulse Common Stock outstanding immediately prior to the
Effective Time (the "Stock Election Number"), all Cash Election Shares and Non-
Election Shares shall be converted into the right to receive cash, and all
Stock Election Shares shall be converted into the right to receive Technitrol
Common Stock and cash in the following manner:
 
  each Stock Election Share shall be converted into the right to
  receive (i) a number of shares of Technitrol Common Stock equal to
  the product of (x) the Exchange Ratio and (y) a fraction (the "Stock
  Fraction"), the numerator of which shall be the Stock Election
  Number and the denominator of which shall be the total number of
  Stock Election Shares, and (ii) an amount in cash, without interest,
  equal to the product of (x) the Per Share Cash Amount and (y) a
  fraction equal to one minus the Stock Fraction.
 
  For example, if 75% of the outstanding shares of Pulse Common Stock
  elect Technitrol Common Stock, then all holders of Cash Election
  Shares and Non-Election Shares would receive cash of $8.50 per share
  in exchange for their shares of Pulse Common Stock. The Stock
  Election Shares would be exchanged for a combination of Technitrol
  Common Stock and cash based upon a Stock Fraction determined by
  dividing the Stock Election Number (55%) by the Stock Election
  Shares (75%) or eleven-fifteenths ( 11/15). Accordingly, a
  hypothetical Pulse stockholder holding 1,000 shares for which a
  Stock Election is made would be entitled to receive the following
  (assuming the Adjusted Exchange Ratio is .5812):
 
   (1) 426.21 shares of Technitrol Common Stock (the product of (i)
       the Exchange Ratio of .5812, (ii) the Stock Fraction ( 11/15)
       and (iii) the number of shares at issue (1,000)), except that
       the stockholder would actually receive 426 shares and cash in
       lieu of the fractional share; and
 
   (2) $2,266.67 in cash (the product of (i) the Per Share Cash
       Amount of $8.50, (ii) a fraction equal to one minus the Stock
       Fraction ( 4/15) and (iii) the number of shares at issue
       (1,000)).
 
                                       7

  In the event that the number of Cash Election Shares does not exceed the Cash
Election Number and the number of Stock Election Shares does not exceed the
Stock Election Number, all Cash Election Shares shall be converted into the
right to receive cash, all Stock Election Shares shall be converted into the
right to receive Technitrol Common Stock, and the Non-Election Shares, if any,
shall be converted into the right to receive Technitrol Common Stock and cash
in the following manner:
 
  each Non-Election Share shall be converted into the right to receive
  (i) a number of shares of Technitrol Common Stock equal to the
  product of (x) the Exchange Ratio and (y) a fraction (the "Non-
  Election Fraction"), which is the lesser of one (1) or a fraction
  where the numerator shall be the excess of the Stock Election Number
  over the total number of Stock Election Shares and the denominator
  of which shall be the aggregate of the Non-Election Shares and (ii)
  an amount in cash, without interest, equal to the product of (x) the
  Per Share Cash Amount and (y) a fraction equal to one minus the Non-
  Election Fraction.
 
  For example, if 20% of the outstanding shares of Pulse Common Stock elect
cash, 30% elect Technitrol Common Stock and 50% are deemed to have made Non-
Elections, then all holders of Cash Election Shares would receive cash of $8.50
per share in exchange for their shares of Pulse Common Stock, all holders of
Stock Election Shares would receive Technitrol Common Stock, and all holders of
Non-Election Shares would receive a combination of Technitrol Common Stock and
cash based upon a Non-Election Fraction calculated by dividing (i) the excess
of the Stock Election Number over the Stock Election Shares (55%-30%) by the
Non-Election Shares (50%) or one-half ( 1/2). Accordingly, a hypothetical Pulse
stockholder holding 1,000 shares for which a Non-Election was made would be
entitled to receive the following (assuming the Adjusted Exchange Ratio is
 .5812):
 
      (1) 290.6 shares of Technitrol Common Stock (the product of (i) the
    Exchange Ratio of .5812, (ii) the Non-Election Fraction ( 1/2) and (iii)
    the number of shares at issue (1,000), except that the stockholder would
    actually receive 290 shares and cash in lieu of the fractional share; and
 
      (2) $4,250 in cash (the product of (i) the Per Share Cash Amount of
    $8.50, (ii) a fraction equal to one minus the Non-Election Fraction (
    1/2) and (iii) the number of shares at issue (1,000)).
 
  If the tax opinions of counsel to Technitrol and Pulse, respectively, receipt
of which is a condition to each party's obligation to consummate the Merger
(see "TERMS OF THE MERGER--Conditions to the Merger"), cannot be delivered as a
result of insufficient continuity of interest, then the Stock Election Number
shall be increased, and the Cash Election Number correspondingly decreased (if
necessary), to the minimum extent necessary to enable such counsel to deliver
the tax opinions.
 
  A FORM OF ELECTION FOR USE BY PULSE STOCKHOLDERS IN THEIR ELECTION TO RECEIVE
EITHER CASH OR TECHNITROL COMMON STOCK IN EXCHANGE FOR THEIR SHARES OF PULSE
COMMON STOCK IS INCLUDED HEREWITH TO PULSE STOCKHOLDERS OF RECORD AS OF THE
RECORD DATE. To be effective, a Form of Election must be properly completed,
signed and submitted to Registrar and Transfer Company, as exchange agent (the
"Exchange Agent"), accompanied by all stock certificates representing shares of
Pulse Common Stock held by the person submitting such Form of Election (or by a
guarantee of delivery of such certificates in the form set forth in the Form of
Election by a member of any registered national securities exchange, a member
of the National Association of Securities Dealers, Inc. or a commercial bank or
trust company having an office or correspondent in the United States, provided
such certificates are in fact delivered to the Exchange Agent within four (4)
business days as set forth in such guarantee of delivery (a "Guaranteed
Delivery")) and must be received by the Exchange Agent no later than 5:00 p.m.
New York City time on the day one business day prior to the Effective Time.
Until such time, all elections will be revocable. PULSE STOCKHOLDERS WHO FAIL
TO RETURN A FORM OF ELECTION, SUBMIT AN IMPROPERLY COMPLETED FORM OF ELECTION
OR FAIL TO SUBMIT THEIR STOCK CERTIFICATES WITH THEIR FORM OF ELECTION (OR FAIL
TO PROVIDE FOR, AND COMPLY WITH THE REQUIREMENTS OF, GUARANTEED DELIVERY) WILL
BE DEEMED TO HAVE MADE A NON-ELECTION. The Merger Agreement provides that
Technitrol and Pulse will cause the Effective Time to occur as promptly as
practicable after approval and adoption by the shareholders of Technitrol and
the stockholders of
 
                                       8
<PAGE>
 
Pulse of the Merger Agreement and the satisfaction (or waiver, if permissible)
of the other conditions to effectiveness of the Merger set forth in the Merger
Agreement. It is anticipated that the Effective Time will occur on or about
September 29, 1995 or on a date as soon as practicable thereafter. Thus,
stockholders of Pulse are urged to deliver a properly completed Form of
Election together with the applicable stock certificates (or provide for
Guaranteed Delivery) to the Exchange Agent no later than 5:00 p.m., New York
City time, on September 28, 1995, in order to assure that their Form of
Election will be received prior to the Effective Time. Persons who become
stockholders of Pulse after the Pulse Record Date or any other stockholders who
need a Form of Election may obtain copies of the Form of Election upon request
from the Exchange Agent either in writing at 10 Commerce Drive, Cranford, New
Jersey 07016 or by telephone at (800) 368-5948. Technitrol and Pulse will each
use its best efforts to mail or cause to be mailed to all persons who become
holders of Pulse Common Stock between the Pulse Record Date and the day seven
(7) days prior to the anticipated Effective Time a Form of Election and will
make available a Form of Election to all persons who become stockholders of
Pulse after that date.
 
  Effect of Merger on Pulse Stock Options. Upon consummation of the Merger, the
obligations of Pulse with respect to outstanding options issued by Pulse to
purchase shares of Pulse Common Stock will be assumed by Technitrol (the
"Assumed Options"). Each Assumed Option will entitle the holder to purchase the
number of whole shares of Technitrol Common Stock equal to the product of the
number of shares of Pulse Common Stock covered by the Assumed Option
immediately prior to the Effective Time multiplied by the Adjusted Exchange
Ratio, rounded up to the nearest whole number. The per share exercise price of
each Assumed Option will be equal to the exercise price per share of Pulse
Common Stock divided by the Adjusted Exchange Ratio, rounded down to the
nearest whole cent. Each Assumed Option will continue to have and be subject to
all other terms and conditions set forth in the applicable stock option
agreement immediately prior to the Effective Time. See "TERMS OF THE MERGER--
Pulse Stock Options." As promptly as practicable after the Effective Time,
Technitrol will file a registration statement under the Securities Act covering
the shares of Technitrol Common Stock issuable upon exercise of the Assumed
Options.
 
  By their approval and adoption of the Merger Agreement, the stockholders of
Pulse will be deemed to have approved amendments to certain Pulse stock option
agreements and the employee benefit plans to which such agreements relate to
prevent the event of the Merger from terminating any options which would
otherwise become Assumed Options. See "TERMS OF THE MERGER--Pulse Stock
Options."
 
  Stock Ownership Following the Merger. Based upon the number of shares of
Pulse Common Stock outstanding as of the Pulse Record Date (before elimination
of fractional shares and assuming (1) the holders of 50% of the outstanding
shares of Pulse Common Stock will make a Stock Election, and (2) no exercise of
dissenters' rights) and based upon a Technitrol Common Stock closing price of
$16.375 on August 11, 1995, an aggregate of 1,631,790 shares of (1,794,969
shares if the holders of at least 55% of the outstanding shares of Pulse Common
Stock make a Stock Election) Technitrol Common Stock will be issued to Pulse
stockholders in the Merger. Based upon the number of shares of Technitrol
Common Stock issued and outstanding as of the Technitrol Record Date, and after
giving effect to the issuance of 1,631,790 shares of Technitrol Common Stock in
connection with the Merger, former holders of Pulse Common Stock would hold
approximately 21.25% (22.89% if 1,794,969 shares of Technitrol Common Stock are
issued in connection with the Merger) of total outstanding shares of Technitrol
Common Stock. Based on the Assumed Options outstanding as of the Pulse Record
Date, Technitrol will also assume options to purchase approximately 250,000
shares of Technitrol Common Stock.
 
  Market Price Data. Technitrol Common Stock is traded on the ASE under the
symbol "TNL". Pulse Common Stock is quoted on the Nasdaq National Market under
the symbol "PLSE". The following table sets forth the closing prices of
Technitrol Common Stock and Pulse Common Stock on April 21, 1995, the last
trading day before the public announcement of the proposed Merger, and on
August 11, 1995, and the equivalent pro forma per share value of Pulse Common
Stock for each date (calculated by multiplying the Exchange Ratio by the
closing price of Technitrol Common Stock on such dates).

(1) If the Average Closing Price of Technitrol Common Stock was $13.375, the
    Exchange Ratio would be adjusted from .5812 to .5981. Pulse stockholders
    receiving 50% stock and 50% cash for their shares would receive
    consideration having an aggregate value of $8.25 for each share of Pulse
    Common Stock.
(2) Pulse stockholders receiving 50% stock and 50% cash for their shares would
    receive consideration having an aggregate value of $9.01 for each share of
    Pulse Common Stock.
 
  Reasons for Merger. The Merger offers many potential benefits which the
respective managements and Boards of Technitrol and Pulse believe will
contribute to the success of the combined companies. Technitrol's Electronic
Products Segment (which includes the Fil-Mag Group which manufactures
electronic components and modules in plants in Taiwan and the Philippines) and
Pulse each manufacture electronic products for use in local area networks,
digital communication equipment and data processing equipment. Pulse is well
known for its engineering and research and development capabilities while the
Fil-Mag Group has stressed its manufacturing capabilities. Both companies
manufacture products in the Far East, but in different geographical locations.
Managements of Technitrol and Pulse believe that their electronics businesses
are complementary and that the Merger will enable them to provide broader
product offerings, more effective sales penetration and a pooling of
technological and manufacturing strengths. In addition, the combination of
Technitrol's Electronic Products Segment and Pulse may provide enhanced
opportunities for growth and reduction of duplicative costs.
 
  There are also certain possible risks associated with the Merger. See "RISK
FACTORS."
 
  Recommendation of Technitrol Board. The Board of Directors of Technitrol (the
"Technitrol Board") has unanimously approved the Merger Agreement and believes
that the Merger is fair and in the best interests of Technitrol and its
shareholders. THE TECHNITROL BOARD UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS
OF TECHNITROL VOTE IN FAVOR OF APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.
See "THE MERGER AND RELATED TRANSACTIONS."
 
  Recommendation of Pulse Board. The Board of Directors of Pulse (the "Pulse
Board") has unanimously approved the Merger Agreement and believes that the
Merger is fair and in the best interests of Pulse and its stockholders. THE
PULSE BOARD UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF PULSE VOTE IN FAVOR
OF APPROVAL AND ADOPTION OF THE MERGER AGREEMENT. See "THE MERGER AND RELATED
TRANSACTIONS."
 
  Opinions of Financial Advisors. Legg Mason Wood Walker, Incorporated ("Legg
Mason") has acted as financial advisor to Technitrol in connection with the
Merger and has delivered to the Technitrol Board its written opinion, dated May
23, 1995 (and reaffirmed on August 18, 1995), to the effect that, as of each
such date and based upon and subject to certain matters stated therein, the
consideration to be paid in the Merger is fair from a financial point of view
to the shareholders of Technitrol. The full text of the opinion of Legg Mason
dated May 23, 1995, which sets forth assumptions made and matters considered,
is attached as Annex B to this Proxy Statement. HOLDERS OF TECHNITROL COMMON
STOCK ARE URGED TO READ SUCH OPINION IN ITS ENTIRETY. See "THE MERGER AND
RELATED TRANSACTIONS--Opinions of Financial Advisors--Technitrol's Financial
Advisor."
 
  Oppenheimer & Co., Inc. ("Oppenheimer") has acted as financial advisor to
Pulse in connection with the Merger and has delivered to the Pulse Board its
written opinion, dated May 22, 1995 (and reaffirmed on August 18, 1995), to the
effect that, as of each such date and based upon and subject to certain matters
stated therein, the Merger is fair from a financial point of view to the
stockholders of Pulse. The full text of the opinion of Oppenheimer dated May
22, 1995, which sets forth the assumptions made and matters considered, is
attached as Annex C to this Proxy Statement. HOLDERS OF PULSE COMMON STOCK ARE
URGED TO READ SUCH OPINION IN ITS ENTIRETY. See "THE MERGER AND RELATED
TRANSACTIONS--Opinions of Financial Advisors--Pulse's Financial Advisor."

  Exchange of Pulse Stock Certificates. Stockholders of Pulse who wish to
submit a Form of Election should deliver their stock certificates (or provide
for, and comply with the requirements of, Guaranteed Delivery) together with
such Form of Election to the Exchange Agent no later than 5:00 p.m. New York
City time on the day one business day prior to the Effective Time. Stock
certificates should not be sent to Technitrol or Pulse. If a stockholder does
not submit such holder's stock certificates with a properly completed Form of
Election (or provide for, and comply with the requirements of, Guaranteed
Delivery), then promptly after the Effective Time, a letter of transmittal and
instructions for surrendering stock certificates will be mailed to each such
holder of Pulse Common Stock for use in exchanging such holder's stock
certificates for certificates evidencing Technitrol Common Stock or cash and
for receiving cash in lieu of fractional shares and any dividends or other
distributions to which such holder is entitled as a result of the Merger
(collectively, the "Merger Consideration").
 
  At or prior to the Effective Time, Technitrol will deposit or cause to be
deposited with the Exchange Agent appropriate amounts of Technitrol Common
Stock and cash to comprise the Merger Consideration. Because Guaranteed
Delivery permits the delivery of stock certificates up to three (3) business
days after the Effective Time, the Merger Consideration will not be distributed
until at least three (3) business days after the Effective Time. See "TERMS OF
THE MERGER--Procedures for Exchange of Certificates."
 
  Summary of Federal Income Tax Consequences. Consummation of the Merger is
conditioned upon receipt by Technitrol and Pulse of opinions by their
respective tax counsel to the effect that the Merger will be treated as a
reorganization within the meaning of Section 368(a) of the Internal Revenue
Code of 1986, as amended (the "Code"), and that none of Technitrol, Pulse or
Teco Sub will recognize any income, gain or loss as a result of the Merger.
Assuming the Merger constitutes such a "reorganization," the United States
Federal income tax consequences for holders of Pulse Common Stock should be
generally as follows:
 
    (1) Holders of Pulse Common Stock exchanging their shares solely for
  Technitrol Common Stock (except for cash in lieu of fractional shares) will
  not recognize any gain or loss upon such exchange for Federal income tax
  purposes. The tax basis of such Technitrol Common Stock will equal (except
  for the basis attributable to any fractional shares) the holder's tax basis
  in the Pulse Common Stock surrendered. Provided the Pulse Common Stock so
  surrendered was held as a capital asset at the Effective Time, the holding
  period of the Technitrol Common Stock received will include the holding
  period of the Pulse Common Stock.
 
    (2) Holders of Pulse Common Stock exchanging their shares solely for cash
  should recognize a gain or loss for Federal income tax purposes equal to
  the difference between the cash received and the holder's tax basis in the
  Pulse Common Stock. If the holder held the Pulse Common Stock as a capital
  asset at the Effective Time, such gain or loss should be capital gain or
  loss and, if so treated, will be long-term capital gain or loss if the
  holder's holding period at that time is more than one year; however, the
  Code contains limitations on the extent to which holders may deduct capital
  losses from ordinary income.
 
    (3) Holders of Pulse Common Stock exchanging their shares for both
  Technitrol Common Stock and cash could have their receipt of cash taxed as
  a dividend (however, holders whose relative stock interest in Pulse is
  minimal, who exercise no control over the affairs of Pulse and who
  experience, pursuant to the Merger, a reduction in their proportionate
  stock interest should not receive dividend treatment). Such a holder's tax
  consequences will also depend on whether shares of Pulse Common Stock were
  purchased at different times and prices. If so, while the holder would not
  recognize gain or loss on the shares of Pulse Common Stock exchanged for
  Technitrol Common Stock and the tax basis therein would carry over, the
  holder could recognize gain, but could not recognize loss, on the receipt
  of cash in exchange for other shares of Pulse Common Stock. Such gain might
  be taxed as a dividend, while any disallowed loss would be included in the
  adjusted basis of the Technitrol Common Stock.
 
    (4) The Merger will be a taxable event for holders of Pulse Common Stock
  who perfect appraisal rights under the DGCL and receive solely cash in
  exchange for their shares. Such a holder should recognize capital gain or
  loss, assuming that the shares are held by such holder as a capital asset
  at the Effective Time, equal to the difference between the amount of cash
  received and the holder's tax basis in the shares surrendered.

  For a more complete description of federal income tax consequences of the
Merger, including a discussion concerning receipt of Technitrol Common Stock
and cash in the Merger as well as applicable backup withholding requirements,
see "THE MERGER AND RELATED TRANSACTIONS--Certain Federal Income Tax
Consequences."
 
  Because of the complexity of the tax laws and the individual nature of the
tax consequences of the Merger to each Pulse stockholder, each such stockholder
should consult a tax advisor concerning the applicable federal, state, local
and foreign tax consequences of the Merger.
 
  Merger Consideration. Technitrol estimates its total cost of consummating the
Merger, including the Merger Consideration and all fees and expenses, to be
approximately $58.9 million.
 
  Accounting Treatment. As required by generally accepted accounting
principles, the purchase method of accounting will be used by Technitrol to
account for the Merger. See "TERMS OF THE MERGER--Accounting Treatment."
 
  Affiliate Agreements. Prior to the Effective Time, certain persons who may be
deemed to be "affiliates" (as that term is defined for purposes of Rule 145
("Rule 145") promulgated under the Securities Act) of Pulse will enter into
agreements restricting sales, dispositions or other transactions which could
reduce their risk of investment in respect of the shares of Pulse Common Stock
held by them prior to the Merger and the shares of Technitrol Common Stock to
be received by them in the Merger, so as to comply with the requirements of
Rule 145 and federal income tax regulations applicable to reorganizations.
 
  Dissenters' Rights. In connection with the Merger, a holder of shares of
Pulse Common Stock will be entitled to demand appraisal rights in respect of
such shares of Pulse Common Stock under Section 262 of the DGCL ("Section 262")
subject to satisfaction by such stockholder of the conditions for appraisal
rights established by Section 262. Section 262 is set forth in full in Annex D
hereto. Technitrol shareholders will not have appraisal rights in the Merger.
See "PULSE SPECIAL MEETING--Dissenters' Appraisal Rights." The Merger Agreement
may be terminated by either Technitrol or Pulse, and the Merger thereby
abandoned, if Dissenters' Shares represent fifteen percent (15%) or more of the
shares of Pulse Common Stock outstanding on the Pulse Record Date. See "TERMS
OF THE MERGER--Termination or Amendment of Merger Agreement."
 
  Reimbursement of Expenses; Break-Up Fee. If the Merger Agreement is
terminated for a party's material breach or under certain other circumstances,
Pulse or Technitrol may be required to reimburse the other for out-of-pocket
transaction expenses of up to $1,000,000. In addition, Pulse may be required to
pay Technitrol a "break-up fee" of $2,000,000 (with credit for any of
Technitrol's out-of-pocket transaction expenses paid by Pulse) under certain
circumstances if the Pulse Board accepts or recommends to Pulse stockholders an
acquisition proposed by another company; or if (i) the Pulse Board otherwise
changes its recommendation that Pulse stockholders approve the Merger, (ii) the
Pulse stockholders fail to approve the Merger prior to September 30, 1995 or
(iii) Dissenters' Shares equal or exceed 15% of the total Pulse shares
outstanding on the Pulse Record Date, and within nine months of the occurrence
of an event in clause (i), (ii) or (iii), Pulse or its stockholders take
certain actions with regard to another acquisition proposal.
 
  Conditions to the Merger; Termination; Amendment. Consummation of the Merger
is subject to the satisfaction of various conditions, including, among others,
(i) those described above relating to the Federal income tax consequences of
the Merger; (ii) the effectiveness of the Registration Statement and the
absence of any stop order suspending the effectiveness thereof and no
proceeding for that purpose having been initiated by the SEC; (iii) approval of
the Merger Agreement and the Merger by the holders of the requisite number of
shares of Pulse Common Stock and Technitrol Common Stock, respectively; and
(iv) expiration or termination of the applicable waiting period under the Hart-
Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act").
The Merger Agreement may also be terminated under certain other circumstances,
including by mutual written consent of Technitrol and Pulse and by either
Technitrol or Pulse if the other party is in material
 
                                       12
<PAGE>
 
breach of any representation, warranty or covenant contained in the Merger
Agreement or if the Merger is not consummated on or before October 31, 1995.
The Merger Agreement may be amended by the Boards of Directors of Technitrol
and Pulse at any time before or after the approval of the Merger Agreement by
the Technitrol shareholders and Pulse stockholders, provided that after any
such approval has been obtained, no amendment of any of the agreements executed
in connection with the Merger may be made which by law requires the further
approval of the securityholders, without obtaining such further approval. See
"TERMS OF THE MERGER--Termination or Amendment of Merger Agreement."
 
  Proposal to Increase Authorized Shares. On July 26, 1995, the Technitrol
Board approved the Charter Amendment (which would increase the number of
authorized shares of Technitrol Common Stock from 10 million shares to 30
million shares). The Charter Amendment is being proposed so that there are
after the issuance of the shares of Technitrol Common Stock in conjunction with
the Merger: (i) adequate shares of Technitrol Common Stock authorized for
issuance in connection with the continuation of Technitrol's Restricted Stock
Plan; (ii) an adequate number of shares of Technitrol Common Stock available
for issuance upon exercise of the Assumed Options; and (iii) a sufficient
number of additional authorized shares of Technitrol Common Stock which will be
available for issuance in the future. The Technitrol Board believes that the
availability of such shares would provide flexibility for Technitrol in meeting
its possible needs by enabling the Technitrol Board to raise additional capital
through the issuance of Technitrol Common Stock or securities convertible into
or exercisable for Technitrol Common Stock, to declare stock dividends payable
in Technitrol Common Stock, to make additional stock awards under Technitrol's
Restricted Stock Plan, and/or to employ Technitrol Common Stock as a form of
consideration for acquisitions. Other than for the stock portion of the Merger
Consideration and pursuant to Technitrol's Restricted Stock Plan and the
Assumed Options, Technitrol does not presently intend to issue any additional
shares for any specific purpose. There are currently issued and outstanding
6,047,742 shares of Technitrol Common Stock. There are presently 3,952,258
shares available for issuance in the future. Between 1,631,790 to 1,794,969
shares of Technitrol Common Stock are expected to be issued to holders of Pulse
Common Stock as part of the Merger Consideration. At the Effective Time,
approximately 250,000 shares of Technitrol Common Stock will be reserved for
issuance upon exercise of the Assumed Options. The Charter Amendment is being
recommended to Technitrol's shareholders at this time, rather than in
connection with each specific issuance of shares that may be proposed in the
future, in order to avoid any unnecessary expense and delay in connection with
such future specific issuances of shares because of the need for shareholder
approval of additional authorized shares. Such a delay and accompanying expense
could have consequences which may not be in the best interests of Technitrol
and its shareholders. If the Charter Amendment is adopted, the power of the
Technitrol Board to issue additional stock could enable the Technitrol Board to
delay, deter or prevent changes in control or management of Technitrol. See
"PROPOSAL TO INCREASE AUTHORIZED SHARES OF TECHNITROL COMMON STOCK."
 
  The Technitrol Board has unanimously approved the Charter Amendment. THE
TECHNITROL BOARD RECOMMENDS THAT SHAREHOLDERS VOTE IN FAVOR OF APPROVAL AND
ADOPTION OF THE AMENDMENT TO THE ARTICLES OF INCORPORATION TO INCREASE THE
NUMBER OF AUTHORIZED SHARES OF TECHNITROL COMMON STOCK. See "PROPOSAL TO
INCREASE AUTHORIZED SHARES OF TECHNITROL COMMON STOCK."
 
  Dividend Policy. The Technitrol Board makes dividend decisions on a quarterly
basis, based on an evaluation of Technitrol's results of operations, financial
position, business needs, capital and surplus requirements and other relevant
considerations. Through the quarter ended March 31, 1995, the Technitrol Board
has declared 77 consecutive quarterly dividends. See "DIVIDEND POLICY."
 
  Anti-takeover Provisions of Pennsylvania Law and Technitrol's Articles of
Incorporation and Bylaws. Upon consummation of the Merger, the stockholders of
Pulse, a corporation organized under the laws of Delaware, will become
shareholders of Technitrol, a corporation organized under the laws of
Pennsylvania. Certain provisions of Pennsylvania Law and of Technitrol's
Articles of Incorporation and Bylaws may have the effect of delaying, deterring
or preventing changes in control or management of Technitrol. Technitrol is
subject to the provisions of Chapter 25, subchapter F of the Pennsylvania
Business Corporation Law, which has the
 
                                       13
<PAGE>
 
effect of restricting changes in control of a company. Technitrol's Articles of
Incorporation and Bylaws provide (i) for a Board of Directors only one-third of
which is elected each year, (ii) a limitation on the number of Directors on the
Technitrol Board to nine, (iii) that twenty percent of the shareholders are
required to call a special meeting of the shareholders, (iv) for approval of
seventy-five percent (75%) of voting shareholders to amend bylaws concerning
the number, terms and removal of the Technitrol Board, and (v) for approval of
seventy-five percent (75%) of voting shareholders to approve a merger, a sale
of substantially all of Technitrol's assets, or an issuance or delivery of
securities in exchange for assets of another corporation under certain
circumstances. In addition, if the Charter Amendment is adopted, the power of
the Technitrol Board to issue stock could enable the Technitrol Board to delay,
deter or prevent changes in control or management of Technitrol. See
"DESCRIPTION OF TECHNITROL CAPITAL STOCK," "COMPARISON OF RIGHTS OF HOLDERS OF
TECHNITROL COMMON STOCK AND HOLDERS OF PULSE COMMON STOCK," and "PROPOSAL TO
INCREASE AUTHORIZED SHARES OF TECHNITROL COMMON STOCK."

              TECHNITROL MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
INTERIM PERIOD COMPARISON
 
  The results for the first six months of 1995 have been prepared by
Technitrol's management without audit or participation by its independent
auditors. In the opinion of management, the financial statements fairly
present the results of Technitrol's operations for the period presented and
the consolidated balance sheet at June 30, 1995. To the best knowledge and
belief of Technitrol, all normal recurring accruals and adjustments have been
made to properly reflect income and expenses attributable to this period.
 
 Liquidity and Capital Resources. Cash and cash equivalents totalled $5.0
million at June 30, 1995, compared to $8.7 million at December 31, 1994.
Working capital was $31.3 million, compared to $30.2 million at the end of
last year.
 
  Operating activities provided $2.8 million in cash for the half year.
Contributing to the positive cash flow were net earnings of $3.7 million and
depreciation and amortization of $2.7 million. In addition, accounts payable
plus accrued expenses increased $1.6 million. Offsetting that favorable cash
impact was a $1.0 million increase in accounts receivable and a $3.4 million
increase in inventory. In general, sales increases caused the rise in payables
and receivables. The inventory increase was primarily within Technitrol's
Metallurgical Products Segment which has experienced on-going customer demand
for "Just in Time" deliveries.
 
  Cash used in investing activities was $7.7 million. Capital expenditures
made during the half totalled $2.9 million. Common stock warrants regarding
Pulse were purchased for $4.8 million during the second quarter. (See Note 5
to Technitrol Consolidated Financial Statements on page F-6.)
 
  Cash provided by financing activities was $1.0 million for the first six
months of 1995. Debt proceeds net of repayments were $2.2 million and were
used primarily for the purchase of the Pulse stock warrants. Separately,
dividends of $1.2 million were paid.
 
  In connection with its financing activities relating to the cash portion of
the Merger, on June 29, 1995, Technitrol entered into a commitment with three
banks. The banks committed to provide up to $50 million of credit to
Technitrol on an unsecured basis of which $20 million would be in the form of
a five year term loan and up to $30 million would be in the form of a three
year revolving line of credit. Closing of the loan transaction pursuant to the
commitment is subject to fulfillment of various conditions which are normal
and customary in transactions of this type. The impact of the loan transaction
has been taken into account in the pro forma financial statements appearing
elsewhere herein as though the refinancing had been effected for the periods
indicated. Interest rate differences are immaterial. Proceeds of the loan will
be used to refinance existing indebtedness (approximately $16 million), pay
the cash portion of the merger consideration (approximately $24 million) and
related transaction expenses (approximately $2.3 million) with the balance
available to provide working capital and funds for future acquisitions, if
required. Technitrol believes that, when closed, the funds available under the
line of credit will be sufficient for its foreseeable cash needs.
 
  Recent balance sheet composition has been:

  Results of Operations.  Sales for the first half of 1995 totaled $79.4
million, an increase of 9.2% over the $72.8 million sold in the comparable
period of 1994. All three of the Company's product segments experienced an
increase in first half sales from the comparable prior year period. The most
sizable increases occurred in the Electronics Products Segment (which includes
the Fil-Mag Group) and the End User/Finished Products Segment.
 
  The backlog at June 30, 1995 was $29.7 million, compared to $32.2 million at
March 31, 1995 and $28.7 million at December 31, 1994. First half sales
slightly exceeded bookings for both the Electronic Products Segment and the
Metallurgical Products Segment (although in the second quarter domestic
economic activity had an adverse volume impact on a portion of the product
portfolio of Advanced Metallurgy, Inc. ("AMI") and sales exceeding bookings in
recent quarters in the Metallurgical Products Segment). Separately, End
User/Finished Products Segment bookings exceed sales for the six months.
 
  The increased sales of the Electronic Products Segment for the six months
ended June 30, 1995 reflected an increase in Fil-Mag Group sales exceeding a
decrease in the sales of the Components Division. The latter sales decrease
reflected continued softening in the domestic market for the Division's
products. Gross profits for the total Segment increased from comparable prior
year levels, as did operating profits. After tax earnings of the Segment
benefited from the favorable offshore effective tax rates of entities within
the Fil-Mag Group relative to that of the Components Division, which both
manufactures and sells domestically.
 
  The Metallurgical Products Segment's sales increase in the first six months
from the comparable prior year period was primarily due to increased shipments
of Chace Precision Metals, Inc. ("Chace"). While sales and gross profits
increased at Chace, gross profits of the Segment decreased slightly, due in
substantial part to certain raw material cost increases experienced by AMI.
Such raw material cost increases are not expected to continue to affect
results of operations of the Segment beyond the third quarter as cost
increases level off and higher prices are passed on to customers.
 
  End User/Finished Products Segment sales increased primarily as a result of
Lloyd Instruments' shipments exceeding those in the comparable period of 1994.
A portion of that increase was due to Lloyd's increased sales in Germany
attributable to the November 1994 acquisition of the Erichsen product line.
Profits for this Segment increased slightly from the comparable prior year
period, reflecting the benefit of Lloyd's overall sales and profit
improvements.
 
  Total selling, general and administrative expenses of $15.9 million
increased slightly as a percentage of sales for the half from 19.5% in 1994 to
20.1% in 1995. Increased sales resulted in increased selling and marketing
expenses, which rose by approximately $1.2 million. General and Administrative
expenses of Lloyd increased by approximately $400,000, due primarily to
expenses associated with the Erichsen product line acquired in November 1994.
Selling, general and administrative expenses at Chatillon increased by
approximately $400,000 due to increased marketing and selling efforts along
with increased product development efforts. Separately, hiring at the
Corporate level caused increases in salaries and fringes (approximately
$100,000), and related relocation costs.
 
  Net interest expense increased to $548,000 for the half, up from $471,000
for the comparable prior year period. The increase reflected interest paid on
$5 million of incremental borrowing during the second quarter of 1995 used to
purchase stock warrants of Pulse Engineering, Inc.
 
  The effective tax rates in the first half were 35.1% in 1995 and 38.9% in
1994. The decrease was caused by proportionately more taxable income earned by
the Company's offshore operating units, particularly Fil-Mag, which generally
incur lower tax rates than those experienced by Technitrol's domestic
operating units.
 
  Net earnings of $3,712,000, or $.61 per share, were realized in the first
six months of 1995, as compared with $3,112,000, or $.52 per share, earned
during the same period in 1994.
 
FISCAL YEAR COMPARISON
 
  Liquidity and Capital Resources. Cash and cash equivalents totalled $8.7
million at December 31, 1994, compared to $7.7 million a year earlier. Working
capital was $30.2 million, compared to $24.1 million at
 
                                      19
<PAGE>
 
December 31, 1993. Contributing to the year-to-year increase in working
capital was the 1994 acquisition of the Fil-Mag Group as discussed below.
 
  Cash provided by operating activities was $9.6 million. The positive cash
flow was composed mainly of net earnings of $6.9 million; depreciation and
amortization of $5.3 million; and increases in accounts payable ($1.1 million)
and accrued expenses ($3.9 million). A cash decrease due to deferred tax
benefits was offset by an increase in income taxes payable. Cash was consumed
by increases in accounts receivable ($4.6 million) and inventories ($2.5
million). Those increases were caused by the increase in sales from 1993 to
1994.
 
  Investing activities consumed $13 million during 1994. Capital expenditures
constituted $4.4 million, excluding acquisitions. Separately, $8.8 million was
paid for the capital stock of the Fil-Mag Group, net of cash acquired.
Financing for the acquisition was provided by drawing down approximately $10
million on a temporary acquisition line of credit from CoreStates Bank, N.A.,
which was subsequently replaced by a three year revolving credit loan.
Projected 1995 capital expenditures are expected to be financed by internally
generated funds.
 
  Cash provided by financing activities was a net $4.2 million. The
aforementioned $10 million loan was the source of funds. Cash consumed by
financing activities was due to combined debt reduction of $3.5 million, and
$2.3 million of dividend payments. It is expected that dividends will continue
to be paid on a quarterly basis during 1995.
 
  Technitrol's foreign sales are conducted primarily through its foreign
subsidiaries, principally in the Far East and Europe. In the Far East,
Technitrol's sales are denominated primarily in U.S. dollars. In Europe, sales
are denominated primarily in local currencies (consisting mainly of English
pounds and French francs) and to a lesser extent in U.S. dollars.
 
  Since a very significant portion of Technitrol's foreign sales are
denominated in U.S. dollars, the Company does not believe that its potential
exposure to currency fluctuations is material to its business. During 1993 and
1994, Technitrol did not purchase any currency exchange forward contracts or
similar instruments generally utilized to reduce the risk of currency
fluctuations. Technitrol will reexamine this policy if sales denominated in
currencies other than U.S. dollars become material to operations.

  Results of Operations. In 1994, sales were $146.4 million compared to $100.5
million in 1993. The 45.7% increase was due to the $30.8 million sales of the
Fil-Mag Group, acquired in January 1994, and a combined sales increase of
$15.1 million realized by the other businesses of Technitrol. All three of
Technitrol's segments experienced increased sales in 1994 from 1993.
 
  The December 31 backlog was $28.7 million in 1994 and $14.9 million in 1993.
Contributing to the increase was the Fil-Mag Group's backlog.
 
  The increase in sales of the Electronic Products Segment to $41.2 million
included the sales of the Fil-Mag Group as noted above. Operating profit of
the Electronics Products Segment increased to $5.0 million in 1994, compared
to $1.7 million in the prior year. The increase reflected the fifty weeks of
profits of the Fil-Mag Group since its acquisition in January 1994. As a
percentage of sales, this segment's annual operating profits equaled
 
                                      20
<PAGE>
 
12.2% which was the highest of Technitrol's three product segments. Year end
backlog and order volumes indicated a softening in the segment's domestic
markets, while offshore demand remained relatively strong.
 
  The Metallurgical Products Segment produced increased sales, operating
profit and operating profit as a function of sales in 1994 as compared to
1993. AMl experienced its largest sales and profit improvements to the product
line which was acquired from Engelhard Corporation in 1991. Housing starts
continue to have an eventual impact on demand for various AMI products.
Management of Technitrol is monitoring the indirect effect that recent
interest rate increases will have on AMI backlog levels which were stable
entering the first quarter of 1995. Separately, Chace sales and operating
profits also grew year-to-year. On-going efforts aimed at cost containment and
quality improvements have contributed to the growth in sales volume and
profits. Chace's proven ability to compete in a demanding industrial market
was reflected by a strong backlog position as it began the new year.
 
  Two of the three operating units which constitute the End User/Finished
Products Segment experienced an increase in sales and operating profits.
Chatillon sales volume and profitability improved in its primary product
families, as the improved economic climate contributed to more favorable
market conditions. Lloyd's year-to-year sales increase reflected incremental
unit sales and the absence of the unfavorable currency translation which
negatively impacted 1993 results. Lower sales and operating profit occurred at
Technitrol's Products Division. Domestic demand for currency counters and
dispensers decreased during 1994, which was also the first full year
subsequent to the Division withdrawing as a provider of engineering services
on a prime contract basis to an agency of the U.S. Government.
 
  Technitrol's selling, general and administrative expenses increased to $27.3
million in 1994 from $19.4 million in 1993. The key reason for the increase
was the addition of the Fil-Mag Group.
 
  Interest expense grew to $1.1 million, caused by the $10 million increase in
outstanding debt to fund the Fil-Mag Group acquisition and rising interest
rates during the year.
 
  1994 income tax expenses increased as a function of pre-tax earnings. The
1994 effective income tax rate rose to 39% from 35% in 1993 as a result of
proportionately higher taxable income being earned by Technitrol's domestic
operations. Effective income tax rates of the domestic operations generally
exceed those of Technitrol's offshore operations.
 
  In 1993, sales increased by 1.9% to $100.5 million. The sales increases of
the Electronic Products Segment and the Metallurgical Products Segment
exceeded the sales decrease experienced by the End User/Finished Products
Segment.
 
  The backlog on December 31, 1993 was $14.9 million compared to $14.2 million
on December 31, 1992.
 
  The Electronic Products Segment sales increased to $9.4 million from $8.2
million in 1992. Sales of the Metallurgical Products Segment increased to
$63.9 million in 1993 from $60.4 million. The 1993 year marked the first full
year of operation at the Export, PA, facility which includes the product line
acquired from Engelhard Corporation in August 1991 and relocated during 1992.
End User/Finished Products Segment sales decreased from $30 million to $27.1
million. This reflected a volume decrease in currency counters and dispensers
in the Products Division. Separately, that division withdrew as a provider of
engineering services on a prime contract basis to an agency of the U.S.
Government. Also causing the sales decline of the segment were unfavorable
currency translation of the sales of Lloyd, and a decrease in the sales of
electronic products of Chatillon.
 
  Total 1993 gross profit dollars approximated those of 1992. However, as a
percentage of sales, 1993 gross profit dropped slightly to 24.6% from 25.2% in
1992. Contributing to the decrease were inventory write-offs and high
production costs incurred at the Export, PA, facility of the Metallurgical
Products Segment and the cost associated with the Petersburg, PA, plant
shutdown of the Electronic Products Segment.
 
  Selling, general and administrative expenses decreased to $19.4 million in
1993, compared to $20 million during the previous year. The decrease reflected
the non-recurring 1992 expenses associated with AMI-DDC (see "Note 2 to
Technitrol Consolidated Financial Statements") and relocating the Engelhard
product line.
 
 
                                      21
<PAGE>
 
  Operating profit of $5.4 million in 1993 represented a 10.6% increase from
year-to-year. The Electronic Products Segment contributed to the increase,
with the Components Division experiencing stronger profits in 1993 as a result
of on-going cost reduction efforts. The operating profit increase of the
Metallurgical Products Segment included improved earnings of the established
operations of AMI and the first full year of contribution of AMI-DDC exceeding
a decrease in profitability on the part of the product line acquired from
Engelhard. The major markets of AMI remained cyclical and reflected general
trends in housing, automotive, appliances and capital equipment. Improved
profits were realized by Chace, as cost improvement programs yielded their
intended results. Regarding the End User/Finished Products Segment, weak
demand caused a decrease in profitability at the Products Division and flat
earnings on certain Chatillon products, which more than offset improved
profits realized by Lloyd.
 
  Interest expense decreased to $0.4 million in 1993 due to lower interest
rates and a reduction in the amount of debt outstanding.
 
  Income tax expenses increased proportionate to 1993 pre-tax earnings, with
the 35% effective income tax rate unchanged from the prior year. Contributing
to the flat effective rate were increased earnings of the operation in Puerto
Rico, which is exempt from U.S. Federal income taxes.
 
  Technitrol adopted Financial Accounting Standard No. 109, "Accounting for
Income Taxes," during 1993. As a result, $261,000 of favorable cumulative
effect on prior years was added to 1993 net earnings.
 
                 PULSE MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
  Pulse reported net income of $3.5 million, or $.55 per share, for fiscal
1995 compared to a net loss of $399,000, or $.07 per share, in fiscal 1994 and
net income of $4.3 million, or $.65 per share, in fiscal 1993. The $3.9
million improvement in fiscal 1995 compared to fiscal 1994 was due primarily
to strong demand for Pulse's products, which has resulted in greater revenues
and improved pricing, lower operating costs due in part to improvements made
in Pulse's operations since the latter part of fiscal 1994 and lower research,
development and engineering ("RD&E") expenses. The decline in fiscal 1994
compared to fiscal 1993 resulted from competitive pricing pressures, higher
production costs, manufacturing complexities and inventory valuation write-
downs associated with production of new products, and higher RD&E costs.
 
  The following table sets forth for the years indicated certain financial
data as a percentage of net sales and the percentage compared to the prior

  Net sales grew 30.9% to $85.4 million in fiscal 1995 compared to $65.2
million in fiscal 1994 and $60.5 million in fiscal 1993. The revenue growth in
fiscal 1995 compared to fiscal 1994 was due primarily to increased shipments
of network modules, telecom products and magnetics products. The following
table sets forth the revenues received by product line during the years
indicated.

(1) Excludes sales of pulse transformers incorporated into Pulse's networking
    modules.
(2) Includes revenue of $2.0 million and $4.3 million in fiscal 1994 and 1993,
    respectively, received from Pulse's former Potter operations, which were
    divested in January 1994.
 
  Pulse experienced significant growth in its shipments of 10Base-T network
modules in fiscal 1995. Shipments of Token Ring network modules in fiscal 1995
increased compared to fiscal 1994 primarily due to significant increases in
the last half of fiscal 1995. Sales of telecom transformer products increased
substantially in fiscal 1995 compared to fiscal 1994, which more than offset
the effect of the decline in sales of Token Ring and 10Base-T transformers.
Sales of power products increased due to greater sales of magnetics products
and more than offset the decline due to the sale of Pulse's Potter operations
in January 1994, which contributed revenues of $2.0 million during fiscal
1994. The aggregate unit volume of sales for all products increased by 45% in
fiscal 1995 compared to fiscal 1994. The increase in sales during fiscal 1994
compared to fiscal 1993 was due to growth in sales of transformers and power
products. Although aggregate unit volume of sales for all products increased
by 38% in fiscal 1994 compared to fiscal 1993, revenue growth was tempered due
to declining prices, particularly in network module products. While demand for
Pulse's products was strong throughout fiscal 1995, demand has recently
softened somewhat. Although Pulse's backlog of unfilled orders at the end of
fiscal 1995 was substantially higher than at the end of fiscal 1994, the
backlog was reduced during the latter part of fiscal 1995 due to the combined
effects of increased shipments and reduced order input, which may impact the
level of future shipments.
 
  Cost of sales increased to $64.4 million in fiscal 1995 compared to $48.1
million and $39.4 million in fiscal 1994 and 1993, respectively, resulting in
gross profit of $21.0 million in fiscal 1995 compared to $17.1 million and
$21.1 million in fiscal 1994 and 1993, respectively. The gross margin (gross
profit as a percentage of net sales) declined to 24.6% in fiscal 1995 compared
to 26.3% in fiscal 1994 and 34.9% in fiscal 1993. Although the gross margin
improved in each quarter during fiscal 1995 (and for the fourth quarter of
fiscal 1995 exceeded the gross margin for fiscal 1994), the decline in gross
margin that occurred in fiscal 1995 and fiscal 1994 reflected changes in
product mix, particularly an increase in the relative amounts of revenue from
lower margin network modules, lower overall prices, and manufacturing
complexities associated with certain product lines. In addition, the decline
in gross margin in fiscal 1995 resulted from inefficiencies related to plant
consolidations in the People's Republic of China (the "PRC"), and the decline
in fiscal 1994 compared to fiscal 1993 was due to increased overhead expenses.
During the 1994 fiscal year, the Company completed the transition of its
Mexican production activities to the PRC. This transition resulted in a
decrease in United States assets, and a corresponding increase in Asian
assets, due to the transfer of machinery and equipment and the relative shift
in inventories from the United States to Asia. Particularly in the last half
of fiscal 1994 and first half of fiscal 1995, Pulse's operating results
reflected its inability to reduce individual product costs to sufficiently
offset declining prices associated with the local area network ("LAN")
components business. The difficulties encountered in manufacturing these
products included higher than anticipated manufacturing costs and lower
production yields due to new product manufacturing complexities. In fiscal
1994, Pulse also provided $1.2 million for losses on inventory valuations
related to certain new products.
 
  While the gross margin for fiscal 1995 was slightly less than the gross
margin for fiscal 1994, gross margins have improved in each quarter of fiscal
1995. During fiscal 1995, Pulse revised its pricing policies relating to the
 
                                      23
<PAGE>
 
manner in which prices for products are developed and approval requirements.
Pulse also increased prices on certain products, including selected network
modules, and discontinued certain products that
were considered unprofitable or inconsistent with product strategy. In
addition, Pulse strengthened materials management and controls, which resulted
in a significant reduction in inventory during fiscal 1995 and cost reductions
on certain products. Pulse has also improved the designs on various products,
thereby reducing materials costs and improving the manufacturability of the
products. Pulse's plant consolidation efforts were completed late in fiscal
1995 when the last of four original PRC facilities was consolidated into
Pulse's two large new manufacturing plants in the PRC.
 
  Research, development and engineering expenses decreased to $4.7 million, or
5.5% of sales, in fiscal 1995 compared to $6.7 million, or 10.2% of sales, in
fiscal 1994 and $4.4 million, or 7.2% of sales in fiscal 1993. The reduction
in RD&E in fiscal 1995 resulted from more focused product development efforts
as well as overall cost reduction measures. Costs have been curtailed most
significantly in connection with Pulse's development activities relating to
wireless LAN products. The increase in RD&E expense in fiscal 1994 compared to
fiscal 1993 was due primarily to new product development activities in the
wireless LAN market and advanced high speed LAN, telecom and power product
components. Certain of these development activities were relocated to Pulse's
Irish facilities in the last half of fiscal 1994, which reduced RD&E expense
thereafter due to the lower overall cost structure for research and
development at those facilities and European Economic Community ("EEC") grants
for research performed in Ireland. Pulse's RD&E expense was reduced by
$280,000 and $652,000 in fiscal 1995 and 1994, respectively, due to EEC
grants. In addition, Pulse has applied for additional grants of up to $560,000
that may be collected during fiscal 1996, although no assurance can be given
that the grants will be received. Despite the reductions in RD&E expense,
Pulse believes that it has maintained product development activities at an
appropriate level. During fiscal 1995, Pulse announced the availability of its
first radio frequency transceivers designed for integration into a variety of
consumer and industrial products. Pulse also announced a strategic technology
relationship with Advanced Micro Devices ("AMD") for the development of a
complete, low-cost wireless LAN card integrated with AMD's media access
controller integrated circuit.
 
  Selling, general and administrative ("SG&A") expenses were $11.7 million, or
13.7% of sales, in fiscal 1995 compared to $11.2 million, or 17.3% of sales,
in fiscal 1994 and $11.2 million, or 18.5% of sales in fiscal 1993. The slight
increase in SG&A expense in fiscal 1995 was caused by a $1.2 million increase
in incentive compensation and costs of approximately $500,000 related to
various legal matters, the effects of which were partially offset by overall
expense controls and the elimination of costs related to Pulse's Potter
operations since their sale in January 1994. SG&A expenses remained constant
in fiscal 1994 compared to fiscal 1993 despite increases in wireless products
and worldwide marketing expenses primarily due to reduced incentive
compensation and the lack of any SG&A expenses relating to Pulse's former
Potter operations following its sale. One matter causing additional legal
expenses was a legal action instituted in February 1995 in which Pulse has
been named as one of several defendants. The plaintiffs allege that they have
experienced physical harm and injury and other damages caused by exposure to
contaminants historically discharged from the former Potter operation plant
site located in Brookhaven, Lincoln County, Mississippi, which Pulse acquired
in 1986 from Varian Associates. Pulse is continuing its analysis of the merits
of the case; however, under any circumstances, Pulse believes that it is
contractually indemnified against any liability or expenses relating to the
action. The entities that Pulse believes are required to indemnify it have not
to date acknowledged their obligations, and Pulse has instituted legal action
to enforce its indemnification rights. Pulse cannot predict the level of
expenses it will be required to incur to defend itself in this action or to
enforce its indemnification rights. While such expenses will continue to be
reflected in Pulse's results of operations to the extent that Pulse is not
reimbursed therefor, Pulse believes that it is entitled to be reimbursed for
all expenses it has already incurred in addition to being indemnified against
any potential liability. The entities with indemnity obligations to Pulse have
performed other obligations relating to environmental issues at the former
Potter operation plant sites.
 
  Interest income, net of interest expense, was $185,000 in fiscal 1995
compared to $355,000 in fiscal 1994 and $239,000 in fiscal 1993. Interest
income declined in fiscal 1995 compared to fiscal 1994 due to lower levels of
investable funds. Interest expense declined due to reduced levels of senior
debt outstanding since the first
 
                                      24
<PAGE>
 
quarter of fiscal 1994, the effect of which was offset by interest on $2.2
million of lease financing obtained during fiscal 1995.
 
  Other expense was $411,000 in fiscal 1995. These expenses consist of costs
incurred in connection with Pulse's activities relating to offers made in
fiscal 1995 to acquire Pulse and, subsequently, the Merger. No similar
expenses were incurred in fiscal 1994 or 1993.
 
  The provision for income taxes as a percentage of income before taxes was
20% in fiscal 1995 and fiscal 1993. There was no provision for income taxes or
income tax benefit in fiscal 1994. The relatively low income tax rates in
fiscal 1995 and fiscal 1993 were primarily the result of a greater proportion
of Pulse's earnings being generated by its foreign subsidiaries, which are
subject to lower tax rates than Pulse's domestic operations. In fiscal 1994
Pulse did not have an income tax benefit despite its loss because the loss was
primarily attributable to losses in foreign locations for which a tax benefit
could not be recognized currently.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Pulse's cash and cash equivalents increased to $15.3 million at July 2, 1995
from $7.1 million at the end of fiscal 1994, while short-term investments
declined to zero at July 2, 1995 from $6.5 million at the end of fiscal 1994.
Pulse has traditionally financed its working capital needs and capital
expenditures through internally generated cash. During fiscal 1995, cash
provided by operations was $9.3 million compared to cash used by operations of
$2.7 million in fiscal 1994. Investing activities used cash of $1.6 million in
fiscal 1995 compared to providing cash of $7.9 million in fiscal 1994,
primarily as a result of reduced sales of short-term investments in fiscal
1995. Financing activities, however, provided cash of $618,000 compared to
using cash of $3.1 million during fiscal 1995 and 1994, respectively, due
primarily to lease financing arrangements entered into in fiscal 1995, which
provided cash of $2.2 million, and reduced amounts of long-term debt
repayments in fiscal 1995.
 
  Pulse made net capital expenditures of $8.1 million, $7.3 million and $1.9
million for fiscal years 1995, 1994 and 1993, respectively. The fiscal 1995
capital expenditures included $4.1 million for expansion of Pulse's facilities
in the PRC, which was completed in the fourth quarter of fiscal 1995, and $1.8
million for automatic and semi-automatic equipment intended for high volume
production. Pulse believes that it has adequate capacity to support
significantly higher levels of sales. For fiscal 1996, Pulse estimates that it
will make capital expenditures of approximately $4 million, primarily for
additional machinery and equipment.
 
  During fiscal 1996, Pulse anticipates that internally generated cash,
including collections on accounts receivable, which are largely generated from
computer and networking companies with a history of timely payment, will be
sufficient to fund its operations. If needed, however, Pulse also has
available a credit line with a commercial bank. The bank credit line is for up
to $5 million, bears interest at the prime rate, has a maturity of December
15, 1995, and has an annual commitment fee of 0.25%. No amounts were
outstanding under the line of credit at July 2, 1995.
 
  Pulse conducts business in various currencies throughout the world. In order
to reduce its exposure to potential transaction losses Pulse periodically
purchases forward rate contracts. The maximum amount of such contracts
outstanding at any time in fiscal 1995 was $500,000. In addition, due to the
less developed nature of the banking system within the PRC, Pulse anticipates
its local currency needs in order to allow sufficient time for conversion from
other currencies. Pulse also faces potential economic and political risks by
operating in the PRC due to the emerging status of the country and its
developing relationship with the United States. Pulse has operated in the PRC
for more than a decade and does not anticipate that those inherent risks will
have a material adverse affect on its operations.

  The following Unaudited Pro Forma Combined Condensed Balance Sheet at June
30, 1995, and the Unaudited Pro Forma Combined Condensed Statements of
Operations for the year ended December 31, 1994 and the six months ended June
30, 1995, combine information for Technitrol and Pulse and include unaudited
pro forma adjustments as described in the accompanying notes. The pro forma
combined condensed statements of operations give effect to the proposed Merger
as if it had occurred at January 1, 1994. The unaudited Pro Forma Combined
Condensed Balance Sheet gives effect to the proposed Merger as if it had
occurred at June 30, 1995. The Pro Forma Combined Condensed Financial
Statements are based on historical financial statements of Technitrol and
Pulse, giving effect to the Merger applying the purchase method of accounting
and the assumptions and adjustments as discussed in the accompanying notes to
the Pro Forma Combined Condensed Financial Statements. These Pro Forma
Combined Condensed Financial Statements are based upon (i) for Technitrol: the
audited consolidated financial statements as of December 31, 1994 and for the
year then ended and the unaudited consolidated financial statements as of June
30, 1995 and for the six months then ended, and (ii) for Pulse: the audited
consolidated balance sheet of July 2, 1995 and the unaudited consolidated
statement of operations for the six-month periods ended July 3, 1994 and
January 1, 1995, and the audited consolidated statement of operations for the
year ended July 2, 1995. These statements are based upon, and should be read
in conjunction with, the historical financial statements of Technitrol and
Pulse which are included elsewhere in this Proxy Statement. The unaudited pro
forma adjustments described in the accompanying notes are based upon
preliminary estimates and certain assumptions that the managements of
Technitrol and Pulse believe are reasonable in such circumstances. The pro
forma data are presented for information purposes only and are not necessarily
indicative of the operating results or financial position that would have
occurred had the Merger been consummated at the dates indicated, nor are they
necessarily indicative of future operating results or financial position.

(1) The cost of the acquisition of Pulse Common Stock is assumed to be to
    approximately $58.9 million. The components of the total purchase price
    are assumed to be as follows:
 
<TABLE>
   <S>                                                            <C>

    Anticipated costs to restructure the operations of Pulse         1.3
    Professional fees and other transaction costs                    2.3
                                                                   -----
                                                                  $58.9 million
</TABLE>
  --------
    (a) Funding sources include $7.9 million of cash on-hand.
 
    For purposes of these Pro Forma Combined Condensed Financial Statements, it
    is assumed that 1,650,000 shares of Technitrol Common Stock will be issued
    to Pulse stockholders. The actual cash and Technitrol Common Stock exchanged
    for the Pulse Common Stock will be determined in accordance with the Merger
    Agreement and Forms of Election received from Pulse stockholders, but is not
    expected to be materially different from the assumptions made here. See
    "TERMS OF THE MERGER--Conversion of Shares of Pulse Common Stock; Election."
 
        Pro forma adjustments to the Combined Condensed Balance Sheet include
    (a) eliminating the equity accounts of Pulse, (b) recording additional
    equity for the following components of the purchase consideration:
    Technitrol Common Stock, stock options assumed, and transaction costs, (c)
    recording of the new debt borrowed and the cash decrease resulting from
    funding the cash portion of the purchase price, (d) establishing a liability
    for anticipated restructuring costs, and (e) establishing a value for
    intangibles and goodwill for the purchase cost in excess of the fair value
    of the assets acquired.
 
       The costs included in the restructuring liability have been estimated in
    accordance with recent pronouncements under generally accepted accounting
    principles and are expected to be incurred under a plan of restructuring to
    be announced within one year of the Effective Time and consists primarily of
    anticipated severance and related payments. The restructuring is expected to
    be completed within two years of the Effective Time and all cash payments
    made under the plan of restructuring will have been made within this two-
    year period.
 
       The pro forma adjustments to the Combined Condensed Balance Sheet assume
    that the Merger occurred on June 30, 1995. For purposes of these Pro Forma
    Combined Condensed Financial Statements, the fair value of Pulse's property,
    plant and equipment is assumed to approximate its current depreciated cost.
    The actual fair value will be determined by independent appraisers and may
    be more or less than the current depreciated costs. Subsequent to the
    Merger, Technitrol will apply the appraisal values and more fully evaluate
    the assets acquired and, as a result, the allocation of purchase price to
    property, plant and equipment may change.
    
       The following pro forma adjustments to the Combined Condensed Statements
    of Operations assume that the Merger occurred on January 1, 1994.
 
(2) Annual selling, general and administrative expenses are increased by $0.8
    million to reflect the amortization of $12.6 million of goodwill and other
    intangibles over a 15-year life.
 
(3) Interest expense on the debt incurred and reduced interest income
    resulting from the use of cash that was previously on-hand and available
    for investment. The rate used to calculate the interest cost of additional
    borrowings is 6.75%. The rate of interest income on available cash is
    assumed to be 3.4%.
 
(4) Adjustment was made to the provision for income taxes, providing for all
    income taxes applicable to the pro forma adjustments at appropriate rates.
    Pro forma results for 1994 assume that the combined entity
 
                                      31

                         NOTES TO UNAUDITED PRO FORMA
             COMBINED CONDENSED FINANCIAL STATEMENTS--(CONTINUED)

   would not have received any additional tax benefit from Pulse's loss for
   the year ended December 31, 1994 and as a result the pro forma effective
   tax rate for 1994 was substantially in excess of the pro forma tax rate in
   1995. The Pulse tax loss for 1994 was generated in a number of foreign tax
   jurisdictions and could not have been applied to Technitrol earnings in the
   United States. In addition, Technitrol did not have operations in the
   foreign jurisdictions where losses were incurred by Pulse during 1994.
 
(5) The historical financial statements of Technitrol include research and
    development expenses classified as a component of cost of goods sold,
    while Pulse has classified such expenses as a component of selling,
    general and administrative expenses. This adjustment reclassifies the
    research and development expenses of Technitrol to selling, general and
    administrative expenses.
 
(6) Pro forma per share data is calculated using the pro forma net earnings
    divided by the pro forma primary shares outstanding (which equal fully
    diluted shares outstanding). The pro forma shares outstanding include
    1,650,000 shares of Technitrol Common Stock issued to the stockholders of
    Pulse under the terms of the Merger (using the assumptions described in
    note (1) above). Common stock equivalents result from outstanding options
    to purchase Pulse Common Stock which will be assumed by Technitrol and
    converted to options to purchase Technitrol Common Stock. It is also
    assumed that the outstanding warrants to purchase Pulse Common Stock will
    be exercised and/or terminated prior to the Effective Time and they are
    therefore excluded from common stock equivalents.
 
(7) Common stock equivalents were not included in computing the 1994 loss per
    share since the effect would have been anti-dilutive.

<PAGE>
 
                                 RISK FACTORS
 
  THE FOLLOWING ARE CERTAIN FACTORS WHICH SHOULD BE CONSIDERED CAREFULLY IN
EVALUATING THE PROPOSALS TO BE VOTED ON AT THE TECHNITROL SPECIAL MEETING AND
PULSE SPECIAL MEETING AND THE ACQUISITION OF THE SECURITIES OFFERED HEREBY.
FOR PERIODS FOLLOWING THE MERGER, REFERENCE TO THE PRODUCTS, BUSINESS,
FINANCIAL RESULTS OR FINANCIAL CONDITION OF TECHNITROL SHOULD BE CONSIDERED TO
REFER TO TECHNITROL AND ITS SUBSIDIARIES, INCLUDING TECO SUB (WHICH SHALL BE
THE SURVIVOR OF THE MERGER WITH PULSE), UNLESS THE CONTEXT OTHERWISE REQUIRES.
 
  Operations in Developing Countries. The majority of Pulse's manufacturing
capacity is located in two proximately situated facilities in the People's
Republic of China (the "PRC"). Pulse has manufactured products in the PRC for
more than the last 10 years. Although the PRC is one of the world's fastest
growing economies, its potential economic, political and labor developments
(including potential political instability, possible nationalization policies,
high inflation, currency fluctuation and uncertain legal system) provide a
number of uncertainties and risks. While the PRC appears currently committed
to an economic system which is based on semi-free enterprise, should the PRC
government adopt economic, legal, or trading policies harmful to private
industry in the future or should the PRC become a highly inflationary economy
without offsetting devaluations, Technitrol's manufacturing capabilities for
electronic components could be significantly disrupted and Technitrol's
operations and financial position could be materially and adversely affected.
 
  Technitrol manufactures electronic components in, among other places, the
Philippines and Taiwan. The current Philippine government has been quite
receptive to foreign investment for manufacturing. There are no assurances
that these receptive policies will continue and, if they do not continue, that
they will not be replaced by economic, tax and/or labor policies which are
less favorable to a foreign manufacturing presence than are the current
policies. Any significant negative change in tax, economic or labor policies
could have a material adverse effect on the operations and financial condition
of Technitrol.
 
  Possible Difficulty in Integration of Certain Operations. Technitrol and
Pulse have entered into the Merger Agreement with the expectation that the
Merger will result in beneficial synergies for the combined companies. See
"THE MERGER AND RELATED TRANSACTIONS." Achieving the anticipated benefits of
the Merger will depend in part upon whether the integration of the businesses
of Pulse and Technitrol's Electronic Products Segment can be accomplished in
an efficient and effective manner. There can be no assurance that this will
occur or that significant cost savings in operations will be achieved. The
successful combination of the two businesses will require, among other things,
integration of their respective product offerings and coordination of their
sales and marketing, research and development and manufacturing efforts. The
difficulties of such integration will be increased by the necessity of
coordinating geographically separated organizations each of which is worldwide
in scope. The integration of certain operations following the Merger will
require the dedication of management resources which may temporarily distract
attention from the day-to-day business of the combined companies. There can be
no assurance that integration will be accomplished smoothly or successfully.
Failure to accomplish effectively the integration of the operations of the two
businesses could have an adverse effect on Technitrol's results of operations,
at least in the short term.
 
  Possible Foreign Currency Losses. Both Pulse and Technitrol conduct
significant off shore manufacturing operations which engage in selling
activities. The currency in which these foreign subsidiaries conduct sales is
primarily the United States dollar. The use of the United States dollar as the
currency for sales made by these foreign subsidiaries gives rise to the risk
of transactional gains or losses as a result of exchange rate fluctuations
between the United States dollar and the local currency of the host country in
which the foreign subsidiary engage in manufacturing activities. Examples of
foreign subsidiaries using the United States dollar as a functional currency
are, in the case of Pulse, the PRC and, in the case of Technitrol, Taiwan and
the Philippines. In order to reduce Technitrol's exposure to transactional
gains or losses resulting from currency fluctuations, Technitrol may, though
to date it has not, purchase currency exchange forward contracts. These
contracts guarantee a predetermined currency exchange rate at the time the
contract is purchased. This will allow Technitrol to shift the risk or benefit
of currency fluctuations from the date of the contract to a third party.
 
                                      33
<PAGE>
 
Technitrol may also consider the use of currency options to reduce the impact
that exchange rate fluctuations could have on gross margin for sales made in
United States dollars but where the products sold are manufactured with labor
and materials paid for in local currencies.
 
  Volatility of Stock Price. The market price of Technitrol Common Stock has
ranged from a high of $16.325 to a low of $13.500 in 1995. The future market
price of Technitrol Common Stock could be subject to wide fluctuations in
response to such factors as substantial variations in quarterly financial
results, announcements of technological innovations or new products by
Technitrol or its competitors, changes in prices of Technitrol's or its
competitors' products and services, changes in product mix, changes in
Technitrol's revenue and revenue growth rates for Technitrol as a whole or for
individual geographic areas, business units, products or product categories,
as well as other events or factors. Statements or changes in opinions,
ratings, revenue or earnings estimates made by brokerage firms or industry
analysts relating to the markets in which Technitrol does business or relating
to Technitrol specifically have resulted, and could in the future result, in
an immediate and adverse effect on the market price of Technitrol Common
Stock. Also, failure to achieve revenue, earnings and other operating and
financial results as anticipated could result in an immediate and adverse
effect on the market price of Technitrol Common Stock. In addition, the stock
market has from time to time experienced price and volume fluctuations which
have particularly affected the market price for the securities of many
cyclical product companies and which often have been unrelated to the
operating performance of these companies. These market fluctuations may
adversely affect the market price of Technitrol Common Stock. In addition,
should the market price of Technitrol Common Stock fall below $13.75 per share
then Technitrol will be required to issue more shares as consideration for the
shares of Pulse Common Stock than has been assumed for purposes of the
Unaudited Pro Forma Combined Condensed Financial Statements and the number of
such additional shares of Technitrol Common Stock issued may result in
significant additional dilution to existing Technitrol shareholders.
 
  Effect of Antitakeover Provisions of Pennsylvania Law and Technitrol's
Charter Documents. Upon consummation of the Merger, certain stockholders of
Pulse will become shareholders of Technitrol, a corporation governed by the
laws of Pennsylvania. Technitrol is subject to the provisions of Chapter 25,
subchapter F of the Pennsylvania Business Corporation Law, which has the
effect of restricting changes in control of a company. Moreover, the following
provisions of Technitrol's Articles of Incorporation and Bylaws could, in some
circumstances, impede a change of control of Technitrol: (i) the
classification of the Technitrol Board into three groups serving staggered
three year terms, so that a majority of the directors is not elected at any
annual meeting; (ii) the limitation on the number of Directors serving on the
Technitrol Board to nine, with no more than three per class; (iii) a provision
that twenty percent of the shareholders are required to call a special meeting
of the shareholders and notice of purpose must be delivered; (iv) a
requirement that shareholder action to amend the bylaws concerning the number,
terms and removal of Directors must be approved by seventy-five percent of
voting shareholders; (v) a requirement that seventy-five percent of voting
shareholders approve a merger, a sale of all or substantially all of
Technitrol's assets, or an issuance or delivery of securities in exchange for
assets of another corporation under certain circumstances; and (vi) the
Charter Amendment, which if adopted, would enable the Technitrol Board to
issue stock potentially to delay, deter or prevent changes in control or

applicable to Technitrol and Technitrol's charter documents may have the
effect of delaying, deterring, or preventing changes in control or management
of Technitrol. See "DESCRIPTION OF TECHNITROL CAPITAL STOCK," "COMPARISON OF
RIGHTS OF HOLDERS OF TECHNITROL COMMON STOCK AND HOLDERS OF PULSE COMMON

RECORD DATE AND OUTSTANDING SHARES
 
  Shareholders of record of Technitrol Common Stock at the close of business
on the Technitrol Record Date (August 11, 1995) are entitled to notice of and
to vote at the Technitrol Special Meeting (and any adjournments or
postponements thereof). As of the close of business on the Technitrol Record
Date, there were 6,047,742 shares of Technitrol Common Stock outstanding, held
by approximately 704 holders of record.
 
VOTE REQUIRED
 
  Approval of the Merger Agreement by Technitrol's shareholders is not
required under Pennsylvania law, but is required by the terms of Technitrol's
Listing Agreement with the ASE (the "ASE Listing Agreement"). The ASE Listing
Agreement requires that the transaction be approved by a majority of the total
votes cast on the proposal at the Technitrol Special Meeting (assuming the
presence of a quorum). Pennsylvania law requires that the Charter Amendment be
approved by a majority of the total votes cast on the proposal at the
Technitrol Special Meeting (assuming the presence of a quorum). Each holder of
Technitrol Common Stock on the Technitrol Record Date is entitled to cast one
vote per share, exercisable in person or by properly executed proxy. The
presence, in person or by properly executed proxy, of the holders of a
majority of the outstanding shares of Technitrol Common Stock entitled to vote
at the Technitrol Special Meeting is necessary to constitute a quorum at the
Technitrol Special Meeting.
 
  See "BENEFICIAL OWNERSHIP OF TECHNITROL COMMON STOCK" for information
concerning the beneficial ownership of Technitrol Common Stock by the
management of Technitrol and by persons owning more than 5% of outstanding
Technitrol Common Stock.
 
PROXIES
 
  This Proxy Statement is being furnished to holders of Technitrol Common
Stock in connection with solicitation of proxies by and on behalf of the
Technitrol Board for use at the Technitrol Special Meeting.
 
  All shares of Technitrol Common Stock that are entitled to vote and are
represented at the Technitrol Special Meeting by properly executed proxies
received prior to or at the Technitrol Special Meeting (and not duly revoked)
will be voted at the Technitrol Special Meeting (or any adjournments or
postponements thereof) in accordance with the instructions indicated on such
proxies. If no such instructions are indicated, such proxies will be voted FOR
the approval and adoption of both the Merger Agreement and the Charter
Amendment.
 
  If any other matters are properly presented for consideration at the
Technitrol Special Meeting (or any adjournments or postponements thereof)
including, among other things, consideration of a motion to adjourn or
postpone the Technitrol Special Meeting to another time and/or place
(including, without limitation, for the purpose of soliciting additional
proxies), the persons named in the enclosed forms of proxy and voting
thereunder will have the discretion to vote on such matters in accordance with
their best judgment.
 
  Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before it is voted. Proxies may be revoked by (i) filing
with the Secretary of Technitrol at or before the taking of the vote at the
Technitrol Special Meeting, a written notice of revocation bearing a later
date than the proxy, (ii) duly executing a later dated proxy relating to the
same shares and delivering it to the Secretary of Technitrol before the taking
of the vote at the Technitrol Special Meeting or (iii) attending the
Technitrol Special Meeting and voting in person (although attendance at the
Technitrol Special Meeting will not in and of itself constitute a revocation
of a proxy). Any written notice of revocation or a subsequent proxy should be
sent so as to be delivered to Technitrol at 1210 Northbrook Drive, Suite 385,
Trevose, Pennsylvania 19053-8406, Attention: Corporate Secretary, or hand
delivered to the Corporate Secretary of Technitrol, in each case before the
taking of the vote at the Technitrol Special Meeting.
 
  Shares represented by proxies that reflect abstentions or "broker non-votes"
(i.e., shares held by a broker or nominee which are represented at the
Technitrol Special Meeting but with respect to which such broker or
 
                                      36
<PAGE>
 
nominee is not empowered to vote) will be counted as shares that are present
and entitled to vote for purposes of determining the presence of a quorum;
however, abstentions or broker non-votes as to approval and adoption of the
Merger Agreement and the Charter Amendment will have the same effect as votes
against such proposals. Although abstentions as to any other proposal which
comes before the Technitrol Special Meeting (and any adjournments or
postponements thereof) also will have the effect of votes against the
proposal, broker non-votes will be treated as unvoted for purposes of
determining approval of such proposal and will not be counted as votes for or
against such proposal.
 
  The cost of the solicitation of Technitrol shareholders will be borne by
Technitrol. Technitrol may retain the services of a proxy solicitation firm to
assist in the solicitation of proxies for a fee not to exceed $5,000.00, plus
reimbursement of reasonable expenses. In addition, Technitrol has agreed to
reimburse brokerage firms and other persons representing beneficial owners of
shares for their expenses in forwarding solicitation material to such
beneficial owners. Proxies also may be solicited by certain Technitrol
directors, officers and employees personally or by telephone, telegram or
other means of communication. Such persons will not receive additional
compensation, but may be reimbursed for reasonable out-of-pocket expenses
incurred in connection with such solicitation.

                             PULSE SPECIAL MEETING
 
DATE, TIME, PLACE AND PURPOSE OF PULSE SPECIAL MEETING
 
  The Pulse Special Meeting will be held at Pulse's headquarters, 12220 World
Trade Drive, San Diego, California 92128 on September 27, 1995 at 8:00 a.m.,
Pacific Daylight Time, for the purpose of voting upon a proposal to approve
and adopt the Merger Agreement.
 
RECORD DATE AND OUTSTANDING SHARES
 
  Stockholders of record of Pulse Stock at the close of business on the Pulse
Record Date (August 11, 1995) are entitled to notice of, and to vote at, the
Pulse Special Meeting and any adjournments or postponements thereof. At the
close of business on the Pulse Record Date, Pulse had outstanding 5,615,243
shares of Pulse Common Stock, excluding 380,894 shares held in Pulse's
treasury, and no shares of Pulse Class B Stock.
 
VOTE REQUIRED
 
  Pulse's Second Restated and Amended Certificate of Incorporation (the "Pulse
Certificate of Incorporation") provides that each issued and outstanding share
of Pulse Stock is entitled to one vote on matters such as approval and
adoption of the Merger Agreement; however, the 380,894 shares of Pulse Common
Stock held in Pulse's treasury will not be voted. Under Delaware law, approval
and adoption of the Merger Agreement requires the approval of a majority of
the issued and outstanding shares of Pulse Stock (exclusive of shares held in
Pulse's treasury). Under Pulse's Bylaws and Delaware law, all other proposals
which may come before the Pulse Special Meeting require the approval of a
majority of the shares of Pulse Common Stock having voting power and present
or represented at the Pulse Special Meeting; however, the presence, in person
or by properly
 
                                      37
<PAGE>
 
executed proxy, of the holders of a majority of the outstanding shares of
Pulse Stock entitled to vote at the Pulse Special Meeting is necessary to
constitute a quorum at the Pulse Special Meeting.
 
  See "BENEFICIAL OWNERSHIP OF PULSE COMMON STOCK" below for information
concerning the beneficial ownership of Pulse Common Stock by the management of
Pulse and by persons owning more than five percent (5%) of Pulse Common Stock.
 
PROXIES
 
  This Proxy Statement is being furnished to holders of Pulse Stock in
connection with the solicitation of proxies by and on behalf of the Pulse
Board for use at the Pulse Special Meeting and any adjournments or
postponements thereof.
 
  All valid proxies received in response to this solicitation will be voted in
accordance with the instructions indicated thereon by the stockholders giving
such proxies. If no instructions are given, such proxies will be voted FOR
approval and adoption of the Merger Agreement.
 
  If any other matters are properly presented for consideration at the Pulse
Special Meeting, or any adjournments or postponements thereof, including,
among other things, consideration of a motion to adjourn or postpone the Pulse
Special Meeting to another time and/or place (including, without limitation,
for the purpose of soliciting additional proxies), the persons named in the
enclosed form of proxy provided by the Pulse Board and voting thereunder will
have the discretion to vote on such matters in accordance with their best
judgment.
 
  Any Pulse stockholder has the power to revoke his or her proxy at any time
before it is voted by filing with the Secretary of Pulse either a written
notice of revocation or a duly executed proxy bearing a later date. Proxies
may also be revoked upon request by any stockholder present at the Pulse
Special Meeting who elects to vote his or her shares in person (although
attendance at the Pulse Special Meeting will not in and of itself constitute a
revocation of a proxy). Any written notice of revocation or a subsequent proxy
should be sent so as to be delivered to Pulse at 12220 World Trade Drive, San
Diego, California 92128, Attention: Acting Corporate Secretary, or hand
delivered to the Corporate Secretary of Pulse, in each case before the taking
of the vote at the Pulse Special Meeting.
 
  Shares represented by proxies that reflect abstentions or "broker non-votes"
(i.e., shares held by a broker or nominee which are represented at the Pulse
Special Meeting but with respect to which such broker or nominee is not
empowered to vote) will be counted as shares that are present and entitled to
vote for purposes of determining the presence of a quorum; however,
abstentions or broker non-votes as to approval and adoption of the Merger
Agreement will have the same effect as votes against such proposal. Although
abstentions as to any other proposal which may come before the Pulse Special
Meeting (and any adjournments or postponements thereof) also will have the
effect of votes against the proposal, broker non-votes will be treated as
unvoted for purposes of determining approval of such proposal and will not be
counted as votes for or against such proposal.
 
  The cost of the solicitation of Pulse stockholders will be borne by Pulse.
Pulse has retained the services of a proxy solicitation firm to assist in the
solicitation of proxies for a fee not to exceed $5,000.00, plus reimbursement
of reasonable expenses. In addition, Pulse has agreed to reimburse brokerage
firms and other persons representing beneficial owners of shares of Pulse
Common Stock for their expenses in forwarding solicitation material to such
beneficial owners. Proxies also may be solicited by certain Pulse directors,
officers and employees personally or by telephone, telegram or other means of
communication. Such persons will not receive additional compensation, but may
be reimbursed for reasonable out-of-pocket expenses incurred in connection
with such solicitation.

DISSENTERS' APPRAISAL RIGHTS
 
  Holders of record of shares of Pulse Common Stock are entitled to certain
appraisal rights under Section 262 ("Section 262") of the DGCL in connection
with the Merger, provided that they comply with the conditions established by
Section 262. Section 262 is reprinted in its entirety as Annex D to this Proxy
Statement. Holders of Technitrol Common Stock are not entitled to appraisal
rights in connection with the Merger. The following discussion is not a
complete statement of the law relating to appraisal rights and is qualified in
its entirety by reference to Annex D. This discussion and Annex D should be
reviewed carefully by any holder who wishes to exercise statutory appraisal
rights or who wishes to preserve the right to do so, as failure to comply with
the procedures set forth herein or therein will result in the loss of
appraisal rights.
 
  Pulse stockholders of record who desire to exercise their appraisal rights
must:
 
  . hold shares of Pulse Common Stock on the date of making a demand for
    appraisal;
 
  . continuously hold such shares through the Effective Time;
 
  . deliver a properly executed written demand for appraisal to Pulse prior
    to the vote by the stockholders of Pulse on the Merger;
 
  . not vote in favor of the Merger nor consent thereto in writing;
 
  . file any necessary petition in the Delaware Court of Chancery (the
    "Delaware Court"), as more fully described below, within 120 days after
    the Effective Time; and
 
  . otherwise satisfy all of the conditions described more fully below.
 
  A record holder of shares of Pulse Common Stock who makes the demand
described below with respect to such shares, who continuously is the record
holder of such shares through the Effective Time, who otherwise complies with
the statutory requirements of Section 262 and who neither votes in favor of
the Merger nor consents thereto in writing will be entitled to an appraisal by
the Delaware Court of the "fair value" of his or her shares of Pulse Common
Stock, exclusive of any element of value arising from the accomplishment or
expectation of the Merger, together with a fair rate of interest, if any, as
determined by the Delaware Court. All references in Section 262 and in this
summary of appraisal rights to a "stockholder" or "holders of shares of Pulse
Common Stock" are to the record holder or holders of shares of Pulse Common
Stock.
 
  Under Section 262, where appraisal rights are available to the stockholders
of a corporation and a merger is to be submitted for approval at a meeting of
such stockholders, as in the case of the Pulse Special Meeting, not less than
20 days prior to the meeting the corporation must notify each of the record
holders of its stock at the close of business on the record date for the
meeting that such appraisal rights are available and include in each such
notice a copy of Section 262. THIS PROXY STATEMENT CONSTITUTES SUCH NOTICE TO
THE HOLDERS OF PULSE COMMON STOCK.
 
  Stockholders who desire to exercise their appraisal rights must not vote in
favor of the Merger and must deliver a separate written demand for appraisal
to Pulse prior to the vote by the stockholders of Pulse on the Merger. A
demand for appraisal must be executed by or on behalf of the stockholder of
record, fully and correctly, as such stockholder's name appears on the
certificate or certificates representing the shares of Pulse Common Stock.
Although a failure to vote against the Merger will not result in a waiver of
appraisal rights, merely voting or delivering a proxy directing a vote against
approval of the Merger will not constitute a demand for appraisal. Pulse
stockholders wishing to exercise appraisal rights should not deliver unmarked
proxies (i.e. proxies without instructions) to Pulse inasmuch as such proxies
will be voted FOR approval of the Merger. See "PULSE SPECIAL MEETING--
Proxies."
 
  A person having a beneficial interest in shares of Pulse Common Stock that
are held of record in the name of another person, such as a broker, fiduciary
or other nominee, must act promptly to cause the record holder to follow the
steps summarized herein properly and in a timely manner to perfect whatever
appraisal rights are available. If the shares of Pulse Common Stock are owned
of record by a person other than the beneficial owner,
 
                                      39
<PAGE>
 
including a broker, fiduciary (such as a trustee, guardian or custodian) or
other nominee, such demand must be executed by or for the record owner. If the
shares of Pulse Common Stock are owned of record by more than one person, as
in a joint tenancy or tenancy in common, such demand must be executed by or
for all joint owners. An authorized agent, including an agent for two or more
joint owners, may execute the demand for appraisal for a stockholder of
record; however, the agent must identify the record owner and expressly
disclose the fact that, in exercising the demand, such person is acting as
agent for the record owner.
 
  A record owner, such as a broker, fiduciary or other nominee, who holds
shares of Pulse Common Stock as a nominee for others may exercise appraisal
rights with respect to the shares held for all or less than all beneficial
owners of shares as to which such person is the record owner. In such case,
the written demand must set forth the number of shares covered by such demand.
Where the number of shares is not expressly stated, the demand will be
presumed to cover all shares of Pulse Common Stock outstanding in the name of
such record owner.
 
  A stockholder who elects to exercise appraisal rights should mail or deliver
his or her written demand to Pulse Engineering, Inc., 12220 World Trade Drive,
San Diego, California 92128, Attention: Acting Corporate Secretary. The
written demand for appraisal should specify the stockholder's name and mailing
address, the number of shares of Pulse Common Stock owned, and that the
stockholder is thereby demanding appraisal of his or her shares. A proxy or
vote against the Merger will not constitute such a demand.
 
  Within ten (10) days after the Effective Time, the Surviving Corporation
must provide notice of the effectiveness of the Merger to all stockholders who
have complied with Section 262 and who are entitled to appraisal rights
thereunder. Within 120 days after the Effective Time, but not thereafter,
either the Surviving Corporation or any stockholder who has complied with the
required conditions of Section 262 may file a petition in the Delaware Court,
with a copy served on the Surviving Corporation in the case of a petition
filed by a stockholder, demanding a determination of the "fair value" of the
shares of all dissenting stockholders. The Surviving Corporation does not
presently intend to file an appraisal petition and stockholders seeking to
exercise appraisal rights should not assume that the Surviving Corporation
will file such a petition or that the Surviving Corporation will initiate any
negotiations with respect to the fair value of such shares. Accordingly, Pulse
stockholders who desire to have their shares appraised should initiate any
petitions necessary for the perfection of their appraisal rights within the
time periods and in the manner prescribed in Section 262. Within 120 days
after the Effective Time, any stockholder who has theretofore complied with
the applicable provisions of Section 262 will be entitled, upon written
request, to receive from the Surviving Corporation a statement setting forth
the aggregate number of shares of Pulse Common Stock with respect to which
demands for appraisal were received by Pulse and the number of holders of such
shares. Such statement must be mailed within ten (10) days after the written
request therefor has been received by the Surviving Corporation or within ten
(10) days after expiration of the time for delivery of demands for appraisal
under Section 262, whichever is later.
 
  If a petition for an appraisal is timely filed, at the hearing on such
petition the Delaware Court will determine which stockholders are entitled to
appraisal rights and will thereafter appraise the shares of Pulse Common Stock
owned by such stockholders, determining the fair value of such shares
exclusive of any element of value arising from the accomplishment or
expectation of the Merger, together with a fair rate of interest, if any, to
be paid upon the amount determined to be the fair value. In determining fair
value, the Delaware Court is to take into account all relevant factors. In
Weinberger v. UOP Inc., the Delaware Supreme Court discussed the factors that
could be considered in determining fair value in an appraisal proceeding,
stating that "proof of value by any techniques or methods which are generally
considered acceptable in the financial community and otherwise admissible in"
court should be considered, and that "fair price obviously requires
consideration of all relevant factors involving the value of a company." The
Delaware Supreme Court stated that in making this determination of fair value
the Delaware Court must consider market value, asset value, dividends,
earnings prospects, the nature of the enterprise and any other facts which
could be ascertained as of the date of the merger which throw light on future
prospects of the merged corporation. In Weinberger, the Delaware Supreme Court
stated that "elements of future value, including the nature of the enterprise,
which are known or susceptible of proof as of the date of the merger and not
the product of speculation, may be considered." Section 262, however,
 
                                      40
<PAGE>
 
provides that fair value is to be "exclusive of any element of value arising
from the accomplishment or expectation of the merger."
 
  Stockholders considering seeking appraisal should recognize that the "fair
value" of their shares determined under Section 262 could be more than, the
same as or less then the consideration they would otherwise receive pursuant
to the Merger Agreement if they do not seek appraisal of their shares. Pulse
stockholders seeking appraisal rights generally will be responsible for filing
an appraisal petition within the appropriate time and funding the expenses of
such an appraisal proceeding. The cost of the appraisal proceeding may be
determined by the Delaware Court and taxed against the parties as the Delaware
Court deems equitable in the circumstances. Upon application of a dissenting
stockholder of Pulse, the Delaware Court may order that all or a portion of
the expenses incurred by any dissenting stockholder in connection with the
appraisal proceeding (including, without limitation, reasonable attorney's
fees and the fees and expenses of experts) be charged pro rata against the
value of all shares of stock entitled to appraisal in order to apportion the
expenses of such proceeding over all shares reaping any potential benefit
therefrom.
 
  Any holder of shares of Pulse Common Stock who has duly demanded appraisal
in compliance with Section 262 will not, after the Effective Time, be entitled
to vote for any purpose any shares subject to such demand or to receive
payment of dividends or other distributions on such shares, except for
dividends or distributions payable to stockholders of record at a date prior
to the Effective Time.
 
  At any time within sixty (60) days after the Effective Time, any stockholder
will have the right to withdraw such demand for appraisal and to accept the
terms offered in the Merger; after this period, the stockholder may withdraw
such demand for appraisal only with the consent of the Surviving Corporation.
If no petition for appraisal is filed with the Delaware Court within 120 days
after the Effective Time, stockholders' rights to appraisal shall cease, and
all holders of shares of Pulse Common Stock will be entitled to receive the
consideration offered pursuant to the Merger Agreement. Inasmuch as the
Surviving Corporation has no obligation to file such a petition and has no
present intention to do so, any holder of shares of Pulse Common Stock who
desires such a petition to be filed is advised to file it on a timely basis.
Any stockholder who withdraws such stockholder's demand for appraisal or who
fails to perfect such demand will be treated as having made a Non-Election
with respect to such stockholder's shares of Pulse Common Stock. See "TERMS OF
THE MERGER--Description of Election Procedures for Exchange of Certificates."
 
                      THE MERGER AND RELATED TRANSACTIONS
 
  The following is a summary of the material terms of the Merger Agreement.
For additional information, reference is made to the Merger Agreement which is
attached to this Proxy Statement as Annex A.
 
BACKGROUND--MATERIAL CONTACTS AND BOARD DELIBERATIONS
 
  Consistent with its ongoing analysis of various business options and the
creation of stockholder value, the Pulse Board and Pulse's management have for
some time considered various alternative business strategies, including
business combination opportunities. As part of that process, in September 1993
Pulse representatives first had contact with representatives of Bel Fuse, Inc.
("Bel Fuse") regarding the possibility of a transaction between the two
companies. During the period of October 1993 through February 1994,
representatives of Pulse and Bel Fuse held discussions regarding a potential
business combination transaction, including meetings of the parties in San
Diego and on the East Coast. These discussions were terminated in February
1994 with no agreement having been reached.
 
  In January 1994, Technitrol completed the acquisition of the Fil-Mag Group,
thus giving Technitrol a significant presence in the electronic components
business for certain applications. The businesses of the Fil-Mag Group (which
became a part of Technitrol's Electronic Products Segment) and Pulse are in
certain respects complementary.
 
                                      41
<PAGE>
 
  In May 1994, representatives of Pulse and Technitrol first informally
discussed the possibility of mutual interest in a business combination
transaction between Pulse and Technitrol. Technitrol initiated this contact.
Pulse officials met with Technitrol representatives in June 1994 in
Philadelphia and again in July 1994 in San Diego, at which point a
confidentiality agreement was signed between the parties and a very limited
amount of confidential information regarding the two companies was exchanged.
A general discussion of possible transactions between the companies ensued at
the meeting in San Diego, although no offers were made. In July 1994, Pulse
management advised Technitrol that it intended to concentrate on certain
operating issues that had arisen within the Pulse organization and that Pulse
did not wish to pursue further discussions of a business combination
transaction with Technitrol. Pulse indicated to Technitrol that, if Pulse once
again considered such a possible transaction, it would contact Technitrol to
determine if Technitrol would be interested in recommencing discussions at
such point.
 
  In August 1994, a Pulse Director received a call from a Bel Fuse advisor
inquiring whether Pulse had an interest in further discussions regarding a
transaction with Bel Fuse. The Pulse Director responded that Pulse continued
to face difficult operating issues, that the Pulse Board believed that Pulse's
stock price had been depressed as a result of recent operating losses, and
that it was not, in the Director's judgment, an appropriate time for Pulse to
consider such a transaction. The Pulse Director said he would be willing to
meet with a representative of Bel Fuse if Bel Fuse requested such a meeting.
 
  On October 4, 1994, 370,700 shares of Pulse Common Stock were traded in a
transaction that Pulse subsequently learned involved a purchase by a Bel Fuse
affiliate. On October 14, 1994, Bel Fuse proposed to the Pulse Board an
acquisition of Pulse and publicly announced an offer (the "Bel Fuse Initial
Offer") of $6.00 for each outstanding share of Pulse Common Stock, consisting
of $3.00 in cash and $3.00 in Bel Fuse stock. In response to the Bel Fuse
Initial Offer, Pulse advised Bel Fuse that it took the offer seriously, that
the Pulse Board would evaluate the offer and would advise Bel Fuse further on
the Pulse Board's position as it developed. The Pulse Board promptly discussed
the possible engagement of a financial advisor to assist it in considering the
Bel Fuse Initial Offer as well as other strategic alternatives. The Pulse
Board subsequently constituted a special committee of Directors (comprising
Directors Clarke H. Bailey, Ronald G. Peters and William R. Stensrud and
herein referred to as the "Pulse Special Committee") to lead consideration of
the Bel Fuse Initial Offer and other strategic alternatives available to
Pulse.
 
  In order to assist in formulating an appropriate response to the Bel Fuse
Initial Offer, the Special Committee and Oppenheimer, which had been retained
as financial advisor, began to explore other potential business combination
and/or strategic alternative transactions for Pulse. In early November 1994, a
Bel Fuse advisor met with a Pulse Director and a representative of Oppenheimer
at which time the Pulse representatives inquired about financing for the Bel
Fuse Initial Offer. The Bel Fuse advisor responded that Bel Fuse was in
discussions with several sources of financing. The Bel Fuse advisor suggested
at this meeting that Bel Fuse was interested in proceeding toward a consensual
transaction with Pulse, although Bel Fuse would not rule out taking a
transaction directly to the Pulse stockholders.
 
  Following public announcement of the Bel Fuse Initial Offer, David R.
Flowers, Chairman and Chief Executive Officer of Pulse, contacted a Technitrol
advisor inquiring as to whether Technitrol might have an interest in reopening
the discussions which were held during the prior summer. Shortly thereafter,
Mr. Flowers had a conversation with Roy E. Hock, Chairman and Chief Executive
Officer of Technitrol, during which Mr. Hock indicated that Technitrol might
have an interest in renewing such discussions and that Mr. Hock would bring
the matter to the attention of the Technitrol Board.
 
  Mr. Hock then convened an informal meeting of the Technitrol Board by
telephone. Mr. Hock briefly described the business of Pulse, its "fit" with
the Electronic Products Segment of Technitrol, the Bel Fuse Initial Offer and
his conversations with Mr. Flowers. After some discussion, the Technitrol
Board authorized Mr. Hock to retain Legg Mason and to proceed with his
exchange with Mr. Flowers. Thereafter, representatives of Legg Mason and
Oppenheimer had several telephone discussions following which Technitrol
agreed to begin collecting due diligence information.
 
                                      42

  On November 6, 1994, the Technitrol Board held a special meeting, attended
by representatives of Legg Mason, at which Technitrol's management made a
presentation with respect to the possible combination of Pulse and the
Technitrol Electronic Products Segment. The business and prospects of the
Technitrol Electronic Products Segment, both alone and combined with Pulse,
were discussed at great length and in great detail. Management also summarized
its preliminary due diligence findings and representatives of Legg Mason
advised the Technitrol Board with respect to a possible transaction with
Pulse. After ample discussion, the Technitrol Board authorized management to
continue discussions with and, at its discretion, to make an offer for Pulse
at approximately $6.00 per share (the same amount as the Bel Fuse Initial
Offer), in stock, cash or a combination thereof, all subject to the completion
of additional due diligence by management and final approval by the Technitrol
Board. Mr. Hock thereafter reported the Technitrol Board's actions to Mr.
Flowers, and it was determined that Technitrol would continue its due
diligence efforts prior to making any offer to acquire Pulse.
 
  In mid-November, Bel Fuse and Technitrol each executed a confidentiality
agreement with Pulse which provided for a 120-day standstill period during
which neither entity would acquire additional shares of Pulse Common Stock,
solicit proxies or otherwise take action with respect to Pulse without the
consent of the Pulse Board. Promptly following execution of these
confidentiality agreements, representatives of Bel Fuse and Technitrol
conducted due diligence visits at Pulse's facilities in San Diego, Ireland and
the PRC. During this same period, Pulse representatives conducted due
diligence at Bel Fuse's facilities in Hong Kong, Macau and the PRC and at
Technitrol's facilities in the Philippines and Taiwan. Technitrol also
undertook substantial additional due diligence to clarify and expand upon its
earlier findings.
 
  Over a three-month period following Pulse's receipt of the Bel Fuse Initial
Offer, Oppenheimer contacted over 130 entities identified by Oppenheimer or
Pulse's management as having a potential for interest in a strategic business
combination transaction with Pulse. While meetings were held with a few
entities, neither these meetings nor any of the solicitations of interest by
Oppenheimer resulted in offers or other serious expressions of interest from
any party (other than Bel Fuse and Technitrol).
 
  On January 25, 1995 the Technitrol Board met and received a report from
Technitrol's management with respect to ongoing due diligence activities. The
Technitrol Board authorized management to continue its due diligence efforts
and discussions with Pulse.
 
  On March 9, 1995 representatives of Pulse (including Mr. Flowers) and
Oppenheimer met in Philadelphia with Thomas J. Flakoll, President and Chief
Operating Officer of Technitrol, and other representatives of Technitrol. At
that meeting, Mr. Flowers provided additional confidential information with
respect to Pulse's business and additional insights into Pulse's manufacturing
strategies in the PRC and Ireland. Due diligence by Technitrol continued on a
number of levels and fronts.
 
  Also in early March, 1995 representatives of Pulse and Oppenheimer met with
representatives of Bel Fuse in New York and New Jersey. Bel Fuse had agreed to
extend the period covered by its confidentiality agreement with Pulse for an
additional 30 days.
 
  In mid-March, 1995 the Pulse Special Committee determined that Pulse should
ask for best and final offers from each of Bel Fuse and Technitrol with
respect to a business combination transaction after Pulse's release of
financial results for Pulse's third fiscal quarter ending on April 2, 1995.
 
  On March 21, 1995 the Technitrol Board met at a regularly scheduled meeting
at which Technitrol's management made another presentation with respect to
Pulse and clarified additional due diligence items. After a full discussion,
the Technitrol Board authorized Technitrol to make an offer to acquire Pulse
for $6.25 per share of Pulse Common Stock, payable $3.125 in cash and $3.125
in Technitrol Common Stock subject to final approval by the Technitrol Board.
On March 23, 1995, Technitrol conveyed this offer to Pulse and announced it
publicly.
 
  On March 23, 1995, shortly after receipt of Technitrol's offer, the Pulse
Board met at a regularly scheduled meeting at which it was determined that
Pulse would not respond directly to Technitrol's offer. Rather, the Pulse
 
                                      43
<PAGE>
 
Board decided that, consistent with the mid-March determination of the Pulse
Special Committee, Pulse would provide to each of Technitrol and Bel Fuse
certain additional confidential financial and operating information and ask
for best and final offers on or before the close of business on April 19, 1995
following the anticipated public announcement date of Pulse's third fiscal
quarter results. Promptly following the Pulse Board meeting, this protocol was
conveyed to each of Technitrol and Bel Fuse.
 
  On April 17, 1995, Pulse released its third fiscal quarter results of
operations which indicated substantial improvements in operations from the
prior two quarters and fiscal 1994. Also on April 17, 1995, the Technitrol
Board convened a special meeting at which Technitrol's management made a
presentation with respect to due diligence findings and the business and
prospects, financial and otherwise, for Pulse alone, the Technitrol Electronic
Products Segment alone, and the two entities combined. Representatives of Legg
Mason attended and advised the Technitrol Board with respect to a possible
transaction with Pulse. A higher value was supported by (i) Pulse's
demonstrated improvements in financial performance and (ii) further
clarification of due diligence matters. After a full and ample discussion, the
Technitrol Board authorized management to make another offer to Pulse of up to
$8.00 per share (assuming 50% to be paid in cash and 50% in Technitrol Common
Stock), payable in a combination of cash and Technitrol stock.
 
  On April 19, 1995, Bel Fuse presented an offer valued at $6.75 per share of
Pulse Common Stock, payable all in Bel Fuse stock, plus a contingent right
intended to provide additional consideration to Pulse's stockholders if the
value of the Bel Fuse stock received for each Pulse share was not equal to
$8.00 at some point within three years following consummation of the proposed
transaction. Further, Bel Fuse proposed that Pulse's stockholders would
receive a 75% interest in the Pulse Spectrum (wireless communication) business
through a spin-off transaction to be effected prior to an acquisition of Pulse
by Bel Fuse.
 
  Also on April 19, 1995, Technitrol offered $7.50 per share for each
outstanding share of Pulse Common Stock, payable to Pulse stockholders in cash
or Technitrol Common Stock, depending upon their individual elections, but
subject to an overall limitation that not more than 50% and 55% of the
aggregate consideration payable would consist of cash and Technitrol Common
Stock, respectively. At the request of Technitrol, Mr. Flakoll, together with
Technitrol's legal counsel (who is also a member of the Technitrol Board) and
a representative of Legg Mason, met in San Diego on April 19, 1995 with Mr.
Flowers, a member of the Pulse Board, Pulse's inside legal counsel and a
representative of Oppenheimer. The parties discussed Pulse and its business,
markets, recent performance and prospects (both independently and together
with the Technitrol Electronic Products Segment). The representatives of
Technitrol returned to Philadelphia on April 20, 1995, although discussions
with representatives of Pulse continued, by telephone, on April 20 and April
21. In the course of its discussions with Pulse, Technitrol increased its
offer to $4.25 per share in cash and .2906 shares of Technitrol Common Stock
for each share of Pulse Common Stock, with an election and allocation
procedure such that a Pulse stockholder receiving half Technitrol stock and
half cash for shares of Pulse Common Stock would receive, by virtue of a price
protection provision, no less than $8.25 in consideration and no more than
$9.01 per share of Pulse Common Stock. Mr. Hock then polled the Technitrol
Board and received approval of this offer, subject to final Board approval of
any definitive agreement.
 
  The Pulse Board met on Thursday, April 20, 1995, by telephone and, after
discussion, authorized Pulse's management to negotiate the terms of a
definitive agreement with Technitrol subject to clarification by Technitrol of
a few terms of its offer. On Friday, April 21, 1995, the remaining terms of
Technitrol's offer were clarified to the satisfaction of Pulse, and Pulse
executed a letter agreeing, until May 29, 1995, not to initiate, solicit or
encourage any inquiries, proposals or offers by any person, entity or group
(except Technitrol) relating to any acquisition of Pulse or Pulse Common Stock
(subject, however, to the ability of the Pulse Board to conduct those
activities which it reasonably considered to be required in order to fulfill
its fiduciary obligations to Pulse's stockholders).
 
  A public announcement of Pulse's acceptance of the Technitrol offer as a
basis for negotiation of a definitive agreement was made prior to the opening
of trading on Monday, April 24, 1995. Subsequent to that time, the parties
conducted additional due diligence and negotiated the terms of the Merger
Agreement and related matters.

  On May 22, 1995, the Pulse Board met in New York City. Pulse's management
made a presentation to the Pulse Board with respect to the Merger Agreement.
Representatives of Oppenheimer and Pulse's legal counsel also attended the
meeting, and Oppenheimer delivered its fairness opinion (see "THE MERGER AND
RELATED TRANSACTIONS--Opinions of Financial Advisors--Pulse's Financial
Advisor"). After a full discussion, the Pulse Board, having reviewed a final
draft of the Merger Agreement, authorized Pulse's management to execute the
Merger Agreement and deliver it to Technitrol.
 
  On May 23, 1995, at a regularly scheduled meeting of the Technitrol Board,
Technitrol's management made a presentation to the Technitrol Board with
respect to the Merger Agreement. Representatives of Legg Mason and
Technitrol's legal counsel also attended the meeting, and Legg Mason delivered
its fairness opinion (see "THE MERGER AND RELATED TRANSACTIONS--Opinions of
Financial Advisors--Technitrol's Financial Advisor"). After a full discussion,
the Technitrol Board, having reviewed a final draft of the Merger Agreement,
authorized Technitrol's management to execute the Merger Agreement and deliver
it to Pulse. Immediately following the meeting, the Merger Agreement was
mutually executed and delivered between Pulse and Technitrol and, following
the close of trading on May 23, 1995, the parties issued a joint press release
announcing the Merger Agreement.
 
TECHNITROL'S REASONS FOR THE MERGER
 
  At its meeting on May 23, 1995, the Technitrol Board determined that the
Merger and the Merger Agreement are fair to, and in the best interests of,
Technitrol, its employees, and its shareholders. In reaching this
determination, the Technitrol Board consulted with the management of
Technitrol, as well as its financial and legal advisors, and considered a
number of factors, including the following:
 
  . The size and potential growth in the markets that are served by products
    manufactured by Pulse and the Electronic Products Segment of Technitrol;
 
  . The terms of the Merger Agreement and the other documents to be executed
    in connection with the Merger;
 
  . Review by the Technitrol Board, based in part on a presentation by
    Technitrol's management and legal counsel, regarding the due diligence
    review of Pulse, including (i) the business, operations, earnings,
    financial condition and management philosophy of Pulse on historical,
    prospective and pro forma bases; (ii) product quality, efficacy and
    compatibility, customer information, compatibility of corporate goals and
    objectives and the respective contributions which each of Pulse and
    Technitrol's Electronic Products Segment would bring to a combined
    entity; and (iii) the opportunities for limited cost savings and
    synergies, such as the ability to rationalize production facilities,
    consolidate purchasing, marketing and selling and pool resources to
    develop new products faster, that are expected to result from the Merger;
 
  . Technitrol's strong manufacturing capabilities and Pulse's strong
    engineering and product development capabilities;
 
  . The opportunity that the Merger provides to integrate the management
    teams of Pulse and Technitrol's Electronic Products Segment;
 
  . Pulse's significant manufacturing capabilities and sales organization in
    the Far East and Technitrol's manufacturing and sales organization in the
    same geographic area but different host countries; and
 
  . The ability of Pulse when combined with Technitrol's Electronic Products
    Segment, by virtue of their size and significant manufacturing capacity
    in the Far East, to compete more effectively and efficiently in the
    highly competitive, price and quality driven electronics component
    industry, particularly with respect to large international accounts.
 
  The Technitrol Board determined that the Merger would better serve
Technitrol's basic business strategy for its Electronic Products Segment than
growth through internal means. In particular, the Board considered that a much
broader international presence would be created by the Merger in a fashion
which could probably not be accomplished through any other means.
 
                                      45
<PAGE>
 
  Thus, the Technitrol Board concluded that the Merger would best advance
Technitrol's strategic plan for its Electronic Products Segment because of the
Technitrol Board's belief that the combination of Pulse and Technitrol's
Electronic Products Segment, each with complementary businesses and business
strategies, creates a business segment with greater size, flexibility, breadth
of products, efficiencies, capital strength and profitability than either
would possess on a stand-alone basis. Each possesses distinct but
complementary business strengths which, the Technitrol Board believes, can be
successfully blended.
 
  The Technitrol Board also considered carefully the opinion rendered by Legg
Mason that the consideration to be paid in the Merger is fair from a financial
point of view to the Technitrol shareholders. The analysis and procedures
utilized in the Legg Mason opinion are described under "THE MERGER AND RELATED
TRANSACTIONS--Opinions of Financial Advisors--Technitrol's Financial Advisor."
 
  The Technitrol Board did not assign any specific or relative weight to the
foregoing factors in the course of its consideration.
 
PULSE'S REASONS FOR THE MERGER
 
  The Pulse Board, at its meeting on May 22, 1995, determined that the Merger
and the Merger Agreement are fair to, and in the best interests of, Pulse and
its stockholders. In making this determination, the Pulse Board consulted with
Pulse's management as well as Pulse's financial and legal advisors, and
considered a number of factors, including the following:
 
  . The respective businesses, assets, managements and prospects of Pulse and
    Technitrol;
 
  . The product compatibility, compatibility of corporate goals and
    objectives and the opportunities for cost savings and synergies resulting
    from consolidation of Pulse and Technitrol;
 
  . The results of investigations comparing certain financial and stock
    market information for Pulse and Technitrol with similar information for
    certain other similar companies which are publicly traded;
 
  . The conclusions drawn from a review of the financial terms of certain
    recent business combination transactions which were deemed comparable, in
    whole or in part, to the proposed merger;
 
  . Information regarding historical market prices and other information with
    respect to the Common Stock of each of Pulse and Technitrol;
 
  . The observations and conclusions about the prospects for a Pulse
    strategic business combination with a candidate other than Technitrol;
    and
 
  . The terms and conditions of the proposed Merger, including the tax-
    favored nature of the stock-for-stock component of the Merger
    Consideration and the flexibility afforded Pulse stockholders by the
    election feature of the Merger.
 
  The Pulse Board also considered carefully the opinion rendered by
Oppenheimer that the consideration to be paid to Pulse's stockholders is fair
from a financial point of view. The analysis and procedures utilized in the
Oppenheimer opinion are described under "THE MERGER AND RELATED TRANSACTIONS--
Opinions of Financial Advisors--Pulse's Financial Advisor."
 
  The Pulse Board did not quantify or otherwise assign relative weights to the
factors considered in its deliberations concerning the Merger.
 
OPINIONS OF FINANCIAL ADVISORS
 
  Technitrol's Financial Advisor. Legg Mason has delivered its written opinion
dated May 23, 1995 (the "Legg Mason Opinion") to the Technitrol Board that, as
of such date, the consideration to be paid in the Merger with Pulse is fair,
from a financial point of view, to the holders of Technitrol Common Stock. A
subsequent written opinion dated just prior to the date of this Proxy
Statement was also delivered to the Technitrol Board, which opinion is
substantially identical to the May 23, 1995 opinion. The full text of the Legg
Mason Opinion, which sets forth the assumptions made, matters considered, and
scope and limitations of the review undertaken
 
                                      46
<PAGE>
 
and procedures followed by Legg Mason in rendering its opinion, is attached to
this Proxy Statement as Annex B. Technitrol shareholders are urged to read the
opinion carefully in its entirety. The Legg Mason Opinion to the Technitrol
Board is directed only to the fairness of the consideration from a financial
point of view to the holders of Technitrol Common Stock and does not
constitute a recommendation to any Technitrol shareholder as to how such
shareholder should vote at the Technitrol Special Meeting. No limitations were
imposed by the Technitrol Board upon Legg Mason with respect to the
investigation made or procedures followed in rendering its opinion.
 
  In arriving at its opinion, Legg Mason, among other things: (i) reviewed the
Merger Agreement; (ii) reviewed certain publicly available audited and
unaudited financial statements of Technitrol and Pulse and certain other
publicly available information of Technitrol and Pulse; (iii) reviewed certain
internal information, primarily financial in nature, concerning Technitrol and
Pulse, prepared by their respective managements; (iv) discussed the past and
current operations and the financial conditions and prospects of Technitrol
with senior management of Technitrol; (v) discussed past and current
operations and the financial conditions and prospects of Pulse with senior
management of Pulse; (vi) reviewed forecast financial statements of Technitrol
furnished to Legg Mason by the senior management of Technitrol; (vii) reviewed
forecast financial statements of Pulse furnished to Legg Mason by the senior
management of Pulse; (viii) reviewed forecast financial statements of Pulse
prepared and furnished to Legg Mason by the senior management of Technitrol;
(ix) held meetings and discussions with certain officers and employees of
Technitrol and Pulse concerning the operations, financial condition and future
prospects of the combined company; (x) reviewed recent stock market data
relating to Technitrol and Pulse; (xi) reviewed certain publicly available
financial and stock market data relating to selected public companies that
Legg Mason considered relevant to its inquiry; (xii) analyzed certain publicly
available information concerning the terms of selected merger and acquisition
transactions that Legg Mason considered relevant to its inquiry; (xiii)
considered the pro forma financial effects of the Merger on Technitrol; and
(xiv) conducted such other financial studies, analyses and investigations and
considered such other information as Legg Mason deemed necessary or
appropriate.
 
  In connection with its review, Legg Mason assumed and relied upon the
accuracy and completeness of all financial and other information supplied to
it by Technitrol and Pulse, or publicly available, and did not independently
verify such information. Legg Mason also relied upon the respective
managements of Technitrol and Pulse as to the reasonableness and achievability
of the financial projections (and the assumptions and bases therefor) provided
to it, and assumed that such projections were reasonably prepared on bases
reflecting the best currently available estimates and judgments of the
respective managements as to the future operating performance of Technitrol
and Pulse. Legg Mason was not requested to make, and did not make, an
independent appraisal or evaluation of the assets, properties, facilities or
liabilities of Technitrol or of Pulse and was not furnished with any such
appraisal or evaluation. The Legg Mason Opinion is necessarily based on stock
prices and economic and other conditions and circumstances as existed or in
effect on, and the information made available to it as of, the date of its
opinion. Legg Mason expressed no opinion as to what the value of Technitrol
Common Stock actually will be when issued to Pulse stockholders pursuant to
the Merger Agreement or as to the price or trading range at which shares of
Technitrol Common Stock may trade following the Merger.
 
  In connection with rendering its opinion, Legg Mason performed a variety of
financial analyses, certain of which are summarized below. Legg Mason believes
that its analyses must be considered as a whole and that selecting portions of
the analyses and of the factors considered by it, without considering all
analyses and factors, could create a misleading view of the processes
underlying its opinion. The preparation of a fairness opinion is a complex
process and is not necessarily susceptible to a partial analysis or summary
description. In its analyses, Legg Mason made numerous assumptions about
industry and general economic conditions and other matters, many of which are
beyond the control of either Technitrol or Pulse and may not be indicative of
future results or actual values, which may be significantly more or less
favorable than the estimated values for Pulse derived from such analyses.
Estimates of values of companies or assets do not purport to be appraisals or
necessarily reflect the prices at which companies and assets may actually be
sold. Because such estimates are inherently subject to uncertainty, Legg Mason
assumes no responsibility for their accuracy. The summary set forth below does
not purport to be a complete description of the analyses performed by Legg
Mason in connection with its opinion.
 
                                      47
<PAGE>
 
  Analysis of Consideration to be Paid by Technitrol. At its meeting on May
  --------------------------------------------------
23, 1995, Legg Mason analyzed the value of the consideration to be paid by
Technitrol pursuant to the Merger under the terms of the Merger Agreement.
Based on the information, discussions, meetings, analyses and reviews outlined
above; an assumed continuation of a Technitrol closing market price as existed
on May 22, 1995 of $14.25; and an assumed 50% cash and 50% stock allocation,
Legg Mason estimated that the per share purchase price for Pulse Common Stock
to be paid by Technitrol in the Merger was $8.39. Including the payment of
$4.8 million to acquire a warrant held by a third party to purchase 655,489
shares of Pulse Class B Stock, Legg Mason estimated the total consideration to
be paid to acquire Pulse to be $52.6 million.
 
  Projections. In performing the analyses described below, Legg Mason utilized
  -----------
but did not independently verify Technitrol's and Pulse's historical financial
statements and projections for both companies provided by the management of
Technitrol.
 
  Analyses Relating to Pulse. Legg Mason employed three methodologies for
  --------------------------
purposes of determining a fair valuation range for Pulse. These analyses
consisted of: (i) a discounted cash flow analysis; (ii) a comparison with
certain comparable public companies; and (iii) a comparison of certain
comparable acquisition transactions. Legg Mason also reviewed a leveraged
buyout analysis. Legg Mason advised the Technitrol Board that it relied
primarily on the discounted cash flow analysis because it reflected the
expected future operating performance of Pulse and that the comparable public
company analysis and comparable acquisition transaction analysis were of
limited use because they rely primarily on multiples of the latest twelve
months ("LTM") earnings, which had been negative for Pulse. However, Legg
Mason did consider multiples of LTM revenue, book value and projected net
income as means to confirm and support the discounted cash flow analysis. Legg
Mason also advised the Technitrol Board that its leveraged buyout analysis of
Pulse was utilized principally for analyzing a minimum value for Pulse and was
not used to establish a valuation range.
 
  Discounted Cash Flow Analysis. Legg Mason performed a discounted cash flow
  -----------------------------
analysis of Pulse premised upon the assumptions summarized below. The
discounted cash flow analysis was based upon the financial and operating
information relating to the business, operations and prospects of Pulse
supplied by both Pulse and Technitrol and covered the period from calendar
year 1996 through the end of calendar year 2000.
 
  Using discount rates ranging from 10.0% to 16.0%, Legg Mason calculated the
present value of the projected stream of Net Unlevered Cash Flow (as defined
below) for calendar years 1996 through 2000 and the present value of the
terminal value (the "Terminal Value") of Pulse at December 31, 2000. "Net
Unlevered Cash Flow," as used in the analysis, is defined, for each period, as
projected earnings before interest and taxes ("EBIT"), less taxes at an
estimated rate of 25.0% (reflecting the impact of foreign source income), plus
projected depreciation and amortization, less projected capital expenditures,
plus or minus projected changes in non-cash working capital. The Terminal
Value was computed by multiplying Pulse's projected EBIT by terminal multiples
of 5.0x to 7.0x. Legg Mason adjusted the calculated present value of the Net
Unlevered Cash Flow and Terminal Value by subtracting the debt on Pulse's
balance sheet, subtracting the cost to Technitrol to acquire a warrant to
purchase 655,489 shares of Pulse Class B Stock, adding cash expected to be
received upon the exercise of other warrants and adding excess cash and cash
equivalents (as calculated below) to calculate a range of equity values for
Pulse. Legg Mason believed the ranges of discount rates and terminal multiples
were appropriate in light of Pulse's current performance, projections and its
weighted average cost of capital.
 
  Based on the range of discount rates and terminal multiples referred to
above, Legg Mason calculated a range of equity values for Pulse of $39.1
million to $62.1 million, or $6.57 per share to $10.44 per share of Pulse
stock.
 
  Comparable Public Company Analysis. Legg Mason compared the relevant
  ----------------------------------
historical and current projected financial and operating results of Pulse with
the operating results of selected publicly traded manufacturers of electronic
components for use in local area networks (the "LAN Technologies Comparable
Companies") and a wider universe of general electronic components
manufacturers (the "General Electronic Components Comparable Companies") that
in Legg Mason's judgment were comparable to Pulse (collectively,
 
                                      48
<PAGE>
 
the "Pulse Comparable Companies"). The Pulse Comparable Companies were chosen
by Legg Mason based on general business, operating and financial
characteristics representative of companies in the industry in which Pulse
operates, although Legg Mason recognized that each of the Pulse Comparable
Companies is distinguishable from Pulse in certain respects. The LAN
Technologies Comparable Companies consisted of Bel Fuse, Inc.; GTI
Corporation; and Technitrol, Inc. The General Electronic Components Comparable
Companies consisted of Acme Electric Company; Corcom, Inc.; CTS Corporation;
Data Switch Corporation; ELEXSYS International, Inc.; Golden Systems, Inc.;
Kemet Corporation; Methode Electronics, Inc.; Spectrum Control, Inc.; and
Zytec Corporation.
 
  In performing its analysis, Legg Mason examined both the aggregate market
value of the outstanding common equity (the "Market Value") and the Market
Value plus preferred equity (if any) at liquidation value, minority interests
(if any) and total debt net of excess cash and cash equivalents (the "Market
Capitalization") of the comparable companies. Excess cash and cash equivalents
was calculated as a company's latest publicly reported cash and cash
equivalents less 5% of its LTM revenue. Using each company's Market
Capitalization, Legg Mason calculated multiples of, among other things, each
company's LTM revenue (the "LTM Revenue Multiples"), LTM earnings before
interest, taxes, depreciation and amortization ("EBITDA") (the "LTM EBITDA
Multiples") and LTM EBIT (the "LTM EBIT Multiples") (collectively, the "Market
Capitalization Multiples").
 
  Using each company's Market Value and based on published security analyst
estimates, Legg Mason also calculated multiples of, among other things, each
company's LTM net income (the "LTM Net Income Multiples"), common
stockholders' equity (the "Book Value Multiples") and projected 1996 net
income (the "Projected 1996 Net Income Multiples") (collectively, the "Market
Value Multiples").
 
  Legg Mason advised the Technitrol Board that the comparable public company
analysis was of limited use in formulating its opinion because Pulse's LTM
EBITDA, LTM EBIT and LTM net income margins were 1.4%, -2.5% and -2.1%,
respectively, and consequently did not yield meaningful implied equity values
for Pulse. These margins were low compared to Pulse's historical operating
performance and the median margins of the Pulse Comparable Companies of 9.7%,
4.9% and 4.1% for LTM EBITDA, LTM EBIT and LTM net income, respectively. LTM
EBITDA Multiples, LTM EBIT Multiples and LTM Net Income Multiples are
typically most relevant for valuation purposes. Legg Mason did utilize LTM
Revenue Multiples, Projected 1996 Net Income Multiples and Book Value
Multiples for purposes of supporting and confirming the discounted cash flow
analysis.
 
  Using the foregoing information, Legg Mason derived a range of implied
enterprise values (a theoretical aggregate valuation of a corporate entity
before adjustments for non-operating assets and liabilities) by applying the
aforementioned mean and median Market Capitalization Multiples of the Pulse
Comparable Companies to the appropriate financial statistics of Pulse. The
range of implied enterprise values for Pulse was then adjusted for non-
operating assets and liabilities, by subtracting all debt obligations, adding
excess cash and cash equivalents and then dividing by the number of fully
diluted Pulse shares outstanding (including the 655,489 shares represented by
the warrants). These enterprise values yielded mean and median implied equity
values for Pulse of $73.1 million and $81.6 million, respectively, or $11.24
per share and $12.56 per share, respectively, based on LTM Revenue Multiples
for the LAN Technologies Comparable Companies. Similarly, the analysis yielded
mean and median implied equity values for Pulse of $87.8 million and $65.7
million, respectively, or $13.50 per share and $10.10 per share, respectively,
based on LTM Revenue Multiples for General Electronic Components Comparable
Companies. As a result of Pulse's LTM EBITDA and EBIT margins, mean and median
implied values based on LTM EBITDA Multiples and LTM EBIT Multiples were not
meaningful. Legg Mason derived a range of implied equity values by applying
the mean and median Market Value Multiples of Pulse Comparable Companies to
the appropriate financial statistics of Pulse. The range of implied equity
values was then divided by the number of fully diluted Pulse shares
outstanding. Legg Mason calculated mean and median implied equity values for
Pulse of $51.0 million and $51.0 million respectively, or $7.85 per share and
$7.85 per share, respectively, using Projected 1996 Net Income Multiples and
$75.5 million and $81.6 million,
 
                                      49

respectively, or $11.62 per share and $12.67 per share, respectively, using
Book Value Multiples for the LAN Technologies Comparable Companies. Legg Mason
also calculated mean and median implied equity values of $68.8 million and
$60.3 million, respectively, or $10.58 per share and $9.28 per share,
respectively, using Projected 1996 Net Income Multiples and $79.4 million and
$58.3 million, respectively, or $12.22 per share and $8.97 per share,
respectively, using Book Value Multiples for the General Electronic Components
Comparable Companies. As a result of Pulse's LTM net income margin, mean and
median implied values based on LTM Net Income Multiples were not meaningful.
Legg Mason advised the Board that the comparable public company analysis
derived a per share value for Pulse of $7.85 to $13.50, which supported the
valuation range derived under the discounted cash flow analysis.
 
  Comparable Transaction Analysis. Legg Mason also performed an analysis of
  -------------------------------
comparable acquisition transactions in reaching its opinion. Legg Mason
compared certain financial and operating statistics of Pulse with certain
financial and operating statistics of selected electronic components
manufacturers immediately prior to their being acquired (the "Acquired
Companies"). Legg Mason reviewed 17 completed transactions. While Legg Mason
believed that the Acquired Companies were comparable to Pulse, it recognized
that each of the Acquired Companies is distinguishable from Pulse in certain
respects and was not acquired in circumstances directly comparable to the
Merger. The selected acquisition transactions occurred between 1992 and the
present and include (acquiror/acquired company): Ducommun Inc./Dynatech
Microwave Technology; Carlyle Group L.P./MagneTek Power Technology Systems
(MagneTek, Inc.); Electronic Associates, Inc./Tanon Manufacturing, Inc.;
Vishay Intertechnology, Inc./Vitramon, Inc. and Vitramon Ltd. (Thomas & Betts
Corporation); Valley Forge Scientific Corporation/Diversified Electronics
Corp.; Unitech plc/Intech/Advanced Analog (Intech L.P.); Read-Rite
Corporation/Sunward Technologies, Inc.; Jaco Electronics, Inc./Nexus Custom
Electronics, Inc.; Technitrol, Inc./Fil-Mag Group (FEE Technology S.A.);
Palomar Medical Technologies, Inc./Dynaco Corporation and Dynaco West
Corporation; Signal Technology Corporation/Microwave/Instruments Division
(Systron Donner Corp. of THORN EMI plc); Signal Technology
Corporation/Innowave, Inc.; Whittaker Corporation/Seaton-Wilson Division (BEI
Electronics Inc.); Eldec Corporation/Ferranti Venus Inc. (Ferranti
International Plc); Vishay Intertechnology, Inc./capacitor assets (North
American Philips Corporation of Philips Electronics N.V.); AMP, Inc./Elf
Atochem Sensors, Inc. (Elf Atochem North America, Inc. of Societe Nationale
Elf Aquitaine); and MagneTek Inc./INET Division (Teledyne, Inc.).
 
  In performing its analysis, Legg Mason examined both the amount paid for
each acquired business' common stockholders' equity (the "Purchase Price of
Equity") and the Purchase Price of Equity plus the acquired business' total
debt, preferred equity and minority interest (if any) less cash and cash
equivalents (the "Transaction Value"). Using the Purchase Price of Equity of
each acquired business, Legg Mason calculated multiples of the acquired
business' LTM net income and common stockholders' equity (the "Purchase Price
of Equity Multiples"). Using the Transaction Value of each comparable
acquisition transaction, Legg Mason calculated multiples of, among other
things, the acquired business' LTM revenues, LTM EBITDA and LTM EBIT
(collectively, the "LTM Transaction Value Multiples").
 
  Applying the mean and median Purchase Price of Equity Multiples to Pulse's
common stockholders' equity and dividing by Pulse's fully diluted shares
outstanding, Legg Mason calculated imputed values for Pulse of $113.0 million
and $62.6 million, respectively, or $17.39 per share and $9.63 per share,
respectively. Legg Mason advised the Technitrol Board that it considered
$17.39 per share to be outside a reasonable valuation range for Pulse. Legg
Mason derived a range of implied enterprise values for Pulse by applying the
aforementioned mean and median Transaction Value Multiples to the appropriate
financial statistics of Pulse. The range of implied enterprise values for
Pulse was then adjusted for non-operating assets and liabilities, by
subtracting all debt obligations, adding excess cash and cash equivalents and
then dividing by the number of fully diluted Pulse shares outstanding.
Applying the mean and median Transaction Value Multiples to Pulse's LTM
revenues, Legg Mason calculated imputed values for Pulse of $80.5 million and
$51.9 million, respectively, or $12.39 per share and $7.99 per share,
respectively. Legg Mason advised the Board that values derived by applying
Purchase Price of Equity Multiples to LTM net income and by applying
Transaction Value Multiples to LTM EBITDA and LTM EBIT were not meaningful
because of Pulse's low LTM EBITDA margin and its
 
                                      50
<PAGE>
 
negative LTM EBIT and LTM net income margins. Legg Mason advised the Board
that the comparable acquisition transaction analysis derived a per share value
for Pulse of $7.99 to $12.39 which supported the valuation range derived under
the discounted cash flow analysis.
 
  No company utilized in the comparable acquisition transaction analysis was
identical to Pulse. Legg Mason advised the Board that an analysis of the
results of this comparison was not mathematical; rather, it involved complex
considerations and judgments concerning differences in historical and
projected financial and operating characteristics of the comparable acquired
businesses and other factors that could affect the acquisition value of such
businesses and Pulse.
 
  Leveraged Buyout Analysis. Legg Mason also performed a leveraged buyout
  -------------------------
analysis of Pulse as a means of establishing a floor value for Pulse and did
not rely on it for purposes of establishing a full valuation range. A
leveraged buyout ("LBO") involves the acquisition or recapitalization of a
company financed primarily by incurring debt that is serviced by the post-LBO
operating cash flow of the company. Legg Mason advised the Technitrol Board
that an LBO value tends to be lower than the value derived by other valuation
analyses because the debt servicing requirements of a leveraged company limits
the price able to be paid by a financial buyer. Furthermore, Legg Mason noted
that a financial buyer typically is unable to realize strategic or synergistic
benefits from an acquisition.
 
  Analyses Relating to Technitrol--Pro Forma Merger Analysis. Legg Mason
  ----------------------------------------------------------
reviewed certain financial information for the pro forma combined entity
resulting from the Merger based on the financial and operating information
provided by management of Technitrol and not independently verified by Legg
Mason relating to the business, operations and prospects for each of Pulse,
Technitrol and the pro forma combined entity. Such analysis indicated that,
based on the per share price of Technitrol Common Stock of $14.25 on May 22,
1995, the transaction would be accretive to Technitrol's earnings per share
("EPS") in calendar 1996, 1997 and 1998 with the accretion increasing over
time for the period from 1996 to 1998. Additionally, the analysis indicated
that, unless the price per share of Technitrol Common Stock used for
calculating the exchange ratio under the terms of the Merger Agreement were to
decrease significantly below its May 22, 1995 level, the transaction would not
dilute Technitrol's EPS in 1996 and would remain accretive to Technitrol's EPS
in 1997 and 1998 (with the transaction becoming more dilutive or less
accretive to Technitrol's EPS the lower the per share price of Technitrol
Common Stock). Legg Mason also reviewed the pro forma capital structure of the
combined entity and the ownership interest in the combined entity Pulse
stockholders would have assuming a $14.25 per share price of Technitrol Common
Stock.
 
  Other Factors. In rendering its opinion, Legg Mason considered certain other
  -------------
factors, including a review of the businesses and operations of and the
industries in which Pulse and Technitrol operate, a review of Pulse's and
Technitrol's historical operating results and the financial and operating
information with respect to the business, operations and prospects of Pulse, a
review of the current and historical stock price performance of Pulse and
Technitrol and other factors it deemed relevant.
 
  Legg Mason is an investment banking firm engaged, among other things, in the
valuation of businesses and securities in connection with mergers,
acquisitions, underwritings, sales and distributions of listed and unlisted
securities, private placements and valuations for estate, corporate and other
purposes. Legg Mason is a nationally recognized investment banking firm which
has substantial experience in merger and acquisition transactions. In the
ordinary course of its business, Legg Mason may actively trade in the
securities of Pulse and Technitrol for its own account and the accounts of its
customers, and accordingly, may at any time hold a long or short position in
such securities. A former employee of Legg Mason serves as a director of
Technitrol.
 
  Pursuant to the terms of an engagement letter, Technitrol agreed to pay Legg
Mason $300,000 for acting as financial advisor in connection with the Merger.
Of this amount $100,000 was paid upon the engagement of Legg Mason and
$200,000 is contingent upon the closing of the Merger. In addition, Technitrol
paid Legg Mason a fee of $75,000 for rendering the opinion. Technitrol also
has agreed to reimburse Legg Mason for its out-of-pocket expenses (including
the reasonable fees and expenses of its legal counsel), and to indemnify Legg
Mason

and certain related parties against certain liabilities, including liabilities
under the federal securities laws, arising out of or in connection with the
services rendered by Legg Mason under the engagement letter.
 
  Pulse's Financial Advisor. The Pulse Board retained Oppenheimer to act as
its financial advisor and to render an opinion to the Pulse Board as to the
fairness, from a financial point of view, of the consideration to be received
by the stockholders of Pulse in the Merger.
 
  On May 22, 1995, Oppenheimer delivered to the Pulse Board its opinion that,
as of that date, the consideration to be paid in the Merger to Pulse
stockholders is fair, from a financial point of view, to the stockholders of
Pulse. A subsequent written opinion dated just prior to the date of this Proxy
Statement was also delivered to the Pulse Board, which opinion is
substantially identical to the May 22, 1995 opinion. Oppenheimer's opinion to
the Pulse Board addresses only the fairness to Pulse and its stockholders from
a financial point of view of the consideration to be received in connection
with the Merger, and does not constitute a recommendation to any stockholder
as to how such stockholder should vote at the Pulse Special Meeting.
 
  The full text of the written opinion of Oppenheimer dated the date of this
Proxy Statement is attached hereto as Annex C. Stockholders of Pulse are urged
to read such opinion carefully and in its entirety for a description of the
procedures followed, the factors considered, the assumptions made and scope of
the review undertaken by, as well as limitations on, Oppenheimer in rendering
its opinion.
 
  In connection with the preparation of its opinion, Oppenheimer, among other
things, (i) reviewed selected financial information relating to Pulse and
Technitrol furnished to it by both companies, including certain internal
financial analyses and forecasts prepared by Pulse's and Technitrol's
managements; (ii) reviewed selected publicly available information; (iii) held
discussions with the managements of Pulse and Technitrol concerning the
businesses, past and current business operations, financial condition and
future prospects of both companies, independently and combined, including
certain information prepared by the managements of Pulse and Technitrol
concerning potential cost savings and synergies that could result from the
Merger; (iv) reviewed the Merger Agreement; (v) reviewed the stock price and
trading histories of both companies; (vi) reviewed the valuations of selected
publicly traded companies which it deemed comparable to Pulse and Technitrol;
(vii) compared the financial terms of the Merger with other transactions which
it deemed relevant; (viii) visited certain facilities of both companies; (ix)
interviewed selected customers and suppliers of both companies; (x)
interviewed key lending sources of Technitrol to assess its ability to finance
the transaction and meet future capital requirements; and (xi) made such other
studies, analyses and inquiries and reviewed such other data as it deemed
relevant.
 
  In arriving at its opinion, Oppenheimer did not independently verify the
foregoing information and has relied on all such information being complete
and accurate in all material respects. Furthermore, Oppenheimer did not obtain
any independent appraisal of the properties or assets and liabilities of Pulse
or Technitrol. Although Oppenheimer evaluated the financial terms of the
Merger and participated in discussions concerning the consideration to be
paid, Oppenheimer did not recommend to Pulse any specific consideration to be
paid to Pulse stockholders in the Merger. No other limitations were imposed on
Oppenheimer with respect to the investigations made or procedures followed by
Oppenheimer.
 
  With respect to the financial and operating forecasts (and the assumptions
and bases therefor) of Pulse and Technitrol which Oppenheimer reviewed,
Oppenheimer assumed that such forecasts have been reasonably prepared and has
relied upon estimates and judgments of Pulse and Technitrol managements as to
the future financial performance of both companies, including the cost savings
and synergies resulting from the Merger, and assumed that such forecasts
reflect the best available estimates and judgments of such respective
managements. Oppenheimer also assumed that, consistent with the views
expressed by the managements of Pulse and Technitrol, the company to be formed
from the combination of Technitrol and Pulse (the "Combined Companies") might
gain several strategic advantages resulting in cost savings. Oppenheimer
further relied upon the assurances of the managements of Pulse and Technitrol
that they are unaware of any facts that would make the information provided to
Oppenheimer incomplete or misleading.
 
                                      52
<PAGE>
 
  While Oppenheimer believes that its review, as described above, provides an
adequate basis for its opinion, Oppenheimer's opinion is necessarily based
upon market, economic, and other conditions that exist and can be evaluated as
of the date of the opinion, and on information available to Oppenheimer as of
such date. In addition, in arriving at its opinion, Oppenheimer did not
consider the range of possible tax consequences facing individual Pulse
stockholders, and the valuations per share derived by Oppenheimer are prior to
any tax impact on individual Pulse stockholders. Finally, Oppenheimer assumed
that the Merger would be accounted for under the purchase method of
accounting.
 
  The following paragraphs summarize the most significant quantitative and
qualitative analyses performed by Oppenheimer in arriving at its opinion and
reviewed by the Pulse Board and does not purport to be a complete description
of the analyses performed by Oppenheimer. The information presented below is
based on the financial condition of Pulse and Technitrol as of a date or dates
shortly before the Merger Agreement was executed on May 23, 1995 and stock
price information through the close of the market on May 15, 1995.
 
  Comparable Companies Analysis. Oppenheimer compared certain financial data
  -----------------------------
and multiples of income statement parameters accorded to other publicly traded
companies deemed by Oppenheimer to be comparable to Pulse and the Combined
Companies ("Comparable Companies"). Financial data compared in the Comparable
Companies analysis included market trading data, market valuation data,
operating performance, growth rates, capitalization ratios, ratios of common
stock share prices to historical trailing twelve month ("TTM") and 1995 and
1996 estimated earnings per share, ratios of market value ("Equity Value") to
TTM and 1995 estimated pre-tax earnings, and ratios of market value as
adjusted for debt and cash ("Aggregate Value" or "Total Deal Value") to 1995
and 1996 estimated earnings before interest expense, income taxes,
depreciation and amortization ("EBITDA") and estimated earnings before
interest expense and income taxes ("EBIT" or "Operating Income"). For the
purposes of this analysis, the Comparable Companies selected by Oppenheimer
were Bel Fuse, Inc., GTI Corporation, and as to Pulse, Technitrol, Inc. (the
"Primary Group"), and Burr-Brown Corporation, Computer Products, Inc., Level
One Communications, Inc., MRV Communications, Inc., Vishay Intertechnology,
Inc. and Zilog, Inc. (the "Secondary Group"). Oppenheimer relied upon the
medians of the Primary Group for the valuation multiples for its Comparable
Companies analysis. In cases where Oppenheimer's analysis indicated that a
multiple for a particular company was not meaningful (e.g., because of a
recent depressed level of earnings) Oppenheimer used the multiple of the other
company or companies in the Primary Group.
 
  Pulse Engineering, Inc.--Stand-alone. In using the Comparable Companies
  ------------------------------------
analysis to value Pulse on a stand-alone basis, Oppenheimer analyzed financial
information which included, among other things, (i) operating performance;
(ii) growth rates; (iii) capitalization ratios; (iv) ratios of common stock
share prices to TTM and 1996 estimated earnings per share; (v) ratios of
Equity Value to estimated TTM pre-tax earnings; and (vi) ratios of Aggregate
Value to TTM and 1996 estimated EBITDA and EBIT. For Pulse, in lieu of
meaningful actual TTM data, approximate TTM ("Adjusted TTM") results were
estimated by annualizing the operating results for the six months ended April
2, 1995. Oppenheimer did not use, for the valuation of Pulse on a stand-alone
basis, multiples of calendar 1995 estimated results because Pulse's likely
stand-alone 1995 results appeared, in Oppenheimer's estimation, to be
distorted by temporary factors including short-term under capacity in the
electronic components industry and non-sustainable reductions in Pulse's
marketing, research, development and administrative expenditures.
 
  Oppenheimer noted that the median multiple of share prices to TTM and
calendar 1996 estimated earnings were 12.0x and 10.5x. Applying these median
multiples to Pulse's Adjusted TTM results yielded implied values of Pulse
Common Stock of $3.88 and $4.53 per share. Oppenheimer noted that the median
multiple of Equity Value to TTM estimated pre-tax earnings was 7.3x producing
an implied value of $3.42 per Pulse share. Oppenheimer noted that the median
multiples of Aggregate Value to TTM and 1996 estimated EBITDA were 5.4x and
6.4x, representing Pulse per share values of $5.97 and $7.59, respectively,
and that the median multiples of Aggregate Value to TTM and estimated 1996
EBIT were 7.6x and 8.2x, representing Pulse per share implied value of $4.63
and $5.15, respectively. The foregoing implied values per Pulse share were
compared to the $8.43
 
                                      53
<PAGE>
 
per share value of the Merger consideration based upon Technitrol's May 15,
1995 trading price per common share.
 
  The Combined Companies. In using the Comparable Companies analysis to value
  ----------------------
the Combined Companies, Oppenheimer analyzed financial information which
included, among other things, (i) operating performance; (ii) growth rates;
(iii) capitalization ratios; (iv) ratios of common stock share prices to 1995
and 1996 estimated earnings per share; (v) ratios of Equity Value to 1995
estimated pre-tax earnings; and (vi) ratios of Aggregate Value to 1995 and
1996 estimated EBITDA and estimated EBIT. In valuing the Combined Companies,
Oppenheimer relied upon the average multiples for Bel Fuse, Inc. and GTI
Corporation, the two Primary Group members other than Technitrol.
 
  Oppenheimer noted that the median multiples of share price to calendar 1995
and 1996 estimated earnings per share were 14.6x and 10.7x, respectively.
These multiples, as applied to Oppenheimer's base forecast of the Combined
Companies' results, yielded estimated equity values per Pulse share
attributable to the Merger (including the cash component of the Merger
consideration) of $11.91 and $11.67 per share, respectively. Oppenheimer noted
that the median multiple of Equity Value to 1995 estimated pre-tax earnings
was 12.2x, yielding an estimated equity value per share of Pulse Common Stock
attributable to the Merger of $13.23 per share. Oppenheimer noted that the
median multiples of Aggregate Value to 1995 and 1996 estimated EBITDA were
9.2x and 7.7x, respectively, yielding estimated equity values per Pulse share
attributable to the Merger of $13.72 and $14.77 per share, respectively.
Oppenheimer noted that the median multiples of Aggregate Value to estimated
1995 and 1996 EBIT were 13.6x and 11.9x, respectively, yielding estimated
equity values per Pulse share attributable to the Merger of $14.12 and $16.81
per share, respectively. The foregoing implied values per Pulse share
attributable to the Merger were compared to the Pulse per share values,
ranging from $3.42 per share to $7.59 per share, calculated above for Pulse on
a stand-alone basis.
 
  Oppenheimer noted that, without taking into account any cost savings, the
Merger was projected to be accretive on an earnings per share ("EPS") basis to
Technitrol in each of the next five years.
 
  Oppenheimer did not use, for the valuation of the Combined Companies,
multiples on a TTM basis since the inclusion of Pulse's results in the
combined historical pro forma financials created distorted results due to
Pulse's depressed results on a TTM basis, and because a sufficient number of
other, more meaningful, multiples were available.
 
  Oppenheimer noted that the resulting multiples relied upon for this analysis
are based on statistical analyses and, therefore, are subject to
interpretation.
 
  No company or business used in the Comparable Companies analyses as a
comparison is identical to Pulse or Technitrol. Accordingly, an analysis of
the results of the foregoing is not entirely mathematical; rather, it involves
complex considerations and judgments concerning differences in financial and
operating characteristics and other factors that could affect the public
trading value of the comparable companies or the business segment or company
to which they are being compared.
 
  Analysis of Selected Comparable Merger and Acquisition Transactions.
  -------------------------------------------------------------------
Oppenheimer reviewed the financial terms, to the extent publicly available, of
twenty-three recent mergers and acquisitions in the electronic components
industry. The twenty-three transactions reviewed, listed by acquiree and
acquiror in reverse chronological order of effective date, were the following:
Unisys Corp.-Defense Electronics Business by Loral Corp.; GC Thorsen by Katy
Industries, Inc.; Morgaux, Inc. by Dover Diversified, Inc.; AT&T Global
Information-NCR Microelectric by Hyundai Electronics America, Inc.; nChip, Inc.
by Flextronics International; ElectroCom Automation, Inc. by AEG AG; Sunward
Technologies, Inc. by Read-Rite Corp.; PicoPower Technology, Inc. by Cirrus
Logic, Inc.; Vitramon Ltd. by Vishay Intertechnology, Inc.; Texas Timberjack,
Inc. by Polyphase Corp.; Intech L.P.-Intech/Advanced by Unitech PLC; Brixton
Systems, Inc. by Computer Networking Technology; Prometrix Corp. by Tencor
Instruments, Inc; Advanced Digital Information by Interpoint Corp.; Nasco, Inc.
by Unidare PLC; Sundstrand Data Control by AlliedSignal, Inc.; Resistance
 
                                      54
<PAGE>
 
Technology, Inc. by Selas Corp. of America; SubMicron Systems, Inc. by Trinity
Capital Enterprise; North American Philips-Tantal by Vishay Intertechnology,
Inc.; Hall-Mark Electronics Corp. by Avnet, Inc.; Electroglas, Inc. by an
Investor Group; Base2 Systems, Inc. by Brooktree Corp.; and Alliant
Techsystems-Metrum Sergeant by Group Technologies Corp.
 
  Oppenheimer noted that the median multiples of Total Deal Value to TTM
Operating Income and TTM net income were 12.8x and 22.8x, respectively. The
Combined Companies' TTM Operating Income and TTM net income were estimated
despite Oppenheimer's belief that such TTM data were less meaningful than the
Combined Companies' projected data (see discussion under "Comparable Companies
Analysis"). Oppenheimer calculated these Combined Companies Operating Income
and TTM net income estimates because no multiples of projected data for
comparable transactions were available. For Pulse, in lieu of meaningful
actual TTM data, the Adjusted TTM results were used. Utilizing the median
multiples of Total Deal Value to TTM Operating Income and TTM net income in
valuing the Combined Companies yielded implied equity values per Pulse share
attributable to the Merger of $10.36 and $11.47 per share, respectively.
Utilizing the median multiples of Total Deal Value to TTM Operating Income and
TTM net income in valuing Pulse yielded implied values of $6.91 and $8.43,
respectively, per Pulse share compared to the $8.43 per share value of the
Merger Consideration based upon Technitrol's May 15, 1995 trading price per
common share.
 
  No company, transaction or business used in the selected merger and
acquisition analysis as a comparison is identical to Pulse or Technitrol.
Accordingly, an analysis of the results of the foregoing is not entirely
mathematical; rather, it involves complex considerations and judgments
concerning differences in financial and operating characteristics and other
factors that could affect the acquisition value of the comparable companies or
the business segment or company to which they are being compared.
 
  Discounted Cash Flow Analysis. Oppenheimer conducted a discounted cash flow
  -----------------------------
analysis to estimate the value of a range of projected unlevered free cash
flows that each of Pulse and the Combined Companies are expected to generate
over a five year period ending December 31, 2000. Oppenheimer calculated a
range of terminal equity values (as of December 31, 2000) for Pulse and the
Combined Companies by applying a range of terminal exit multiples of 5.5x to
6.5x projected EBITDA for the calendar year 2000 and adjusting for Pulse's and
the Combined Companies' estimated net debt as of that time. Oppenheimer noted
that this range of exit multiples was in line with the current multiple for
Technitrol as discussed above under "Comparable Companies Analysis." The range
of terminal exit multiples used reflected assumptions regarding the growth and
profitability of Pulse and the Combined Companies beyond calendar year 2000.
The sum of the unlevered free cash flows for such five year period and the
range of terminal equity values were then discounted to derive net present
equity values using a range of discount rates from 15% to 25% for the Combined
Companies and from 20% to 40% for Pulse (the ranges were derived reflecting
Oppenheimer's analysis of the different levels of risk relating to the two
entities). In the case of Pulse, at the mid-point discount rate of 30%, this
implied equity value ranged from $44.0 million to $58.0 million, representing
an estimated equity value of approximately $6.80 to $8.90 per Pulse share. In
the case of the combined companies, at the mid-point discount rate of 20%,
this implied equity value ranged from $205.9 million to $379.7 million,
representing an estimated implied equity value per Pulse share attributable to
the Merger (including the cash component of the Merger consideration) of
approximately $11.23 to $17.11 per share compared to the $8.43 per share value
of the Merger Consideration based upon Technitrol's May 15, 1995 trading price
per common share.
 
  The preparation of a fairness opinion is a complex analytic process
involving various determinations as to the most appropriate and relevant
methods of financial analyses and the application of those methods to the
particular circumstances and, therefore, such an opinion is not readily
susceptible to partial analysis or summary description. Oppenheimer believes
that these analyses must be considered as a whole and that selecting portions
of the analyses or of the summary set forth above, without considering the
analyses as a whole, could create a misleading or incomplete view of the
processes underlying Oppenheimer's opinion. In arriving at its opinion,
Oppenheimer did not attribute any particular weight to any single analysis or
factor considered by it, but rather made qualitative judgments as to the
significance and relevance of each analysis and factor. The summary of
 
                                      55
<PAGE>
 
Oppenheimer's analyses outlined above does not purport to be a complete
description of the analyses underlying Oppenheimer's opinion. In its analyses,
Oppenheimer made numerous assumptions with respect to Pulse and Technitrol,
industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of Pulse
and Technitrol. The estimates contained in such analyses are not necessarily
indicative of actual values or predictive of future results or values, which
may be significantly more or less favorable than those suggested by such
analyses. In addition, analyses relating to the value of businesses or
securities do not purport to be appraisals or to reflect the prices at which
businesses or securities actually may be sold. Accordingly, such analyses and
estimates are inherently subject to substantial uncertainty.
 
  Pursuant to a letter agreement dated October 28, 1994, Pulse engaged
Oppenheimer to provide financial advisory services in connection with the Bel
Fuse Initial Offer and potential acquisition and restructuring alternatives.
Oppenheimer is entitled to a fee of $150,000 for its opinion rendered to the
Pulse Board in connection with the Merger. In addition, Oppenheimer will
receive a transaction fee upon the closing of the Merger, against which its
opinion fee will be credited, tied to a formula percentage of the total
consideration received by Pulse stockholders in the Merger. Under the formula,
Oppenheimer will be paid a fee of 1% of the total consideration received up to
$6.00 per share; 2% of the total consideration received from $6.00 to $7.00
per share; 3% of the total consideration received from $7.00 to $8.00 per
share and 4% of the total consideration received over $8.00 per share. Based
upon the market value per share of Technitrol Common Stock on August 11, 1995,
Oppenheimer's transaction fee would be approximately $800,000. Pulse has also
agreed to reimburse Oppenheimer for its reasonable out-of-pocket expenses and
to indemnify Oppenheimer for certain liabilities relating to or arising out of
services provided by Oppenheimer as financial advisor to Pulse.
 
  Oppenheimer was retained based on its experience as financial advisor in
connection with mergers and acquisitions as well as Oppenheimer's investment
banking relationship and familiarity with Pulse. Oppenheimer has provided
financial advisory and investment banking services to Pulse since 1986, at
which time Oppenheimer, together with management of Pulse and certain other
investors, acquired Pulse from its previous owner. At that time and
subsequently, Oppenheimer affiliates acquired, and in many cases still hold,
significant amounts of Pulse Common Stock and warrants to purchase Pulse
Common Stock. In addition, Oppenheimer employees have served on the Pulse
Board from the time of the 1986 acquisition until mid-1994. Oppenheimer acted
as an underwriter for the initial public offering of Pulse in 1991 and with
respect to that transaction, Oppenheimer has been compensated for such
services in the form of customary underwriting discounts. Oppenheimer also
makes a market in Pulse Common Stock. In the course of its market making and
other activities, Oppenheimer may, from time to time, have a long or short
position in, and buy and sell, securities of Pulse.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The following discussion is a summary of the material United States Federal
income tax consequences of the Merger and is not intended to be a complete
discussion of all potential tax effects that might be relevant to the Merger.
This discussion deals only with citizens or residents of the United States or
domestic corporations (each a "U.S. Holder"). This summary may not be
applicable to certain classes of taxpayers and may not address Federal income
tax consequences for certain Pulse stockholders including, without limitation,
(i) Pulse stockholders who, at the Effective Time, already own some Technitrol
Common Stock, (ii) insurance companies, tax-exempt organizations, financial
institutions, securities dealers and broker-dealers, (iii) foreign persons and
entities, (iv) persons who acquired Pulse Common Stock pursuant to an exercise
of employee stock options or rights or otherwise as compensation, (v) persons
or entities exercising some form of control over Pulse and (vi) persons or
entities holding shares of Pulse Common Stock as part of a straddle or
conversion transaction.
 
  This summary is based on laws, regulations, rulings, practice and judicial
decisions in effect at the date of this Proxy Statement. However, legislative,
judicial or administrative changes or interpretations may be forthcoming that
could alter or modify the statements and conclusions set forth herein. Any
such changes or interpretations may or may not be retroactive and could affect
the tax consequences described herein to stockholders. EACH STOCKHOLDER'S
INDIVIDUAL CIRCUMSTANCES MAY AFFECT THE TAX
 
                                      56
<PAGE>
 
CONSEQUENCES OF THE MERGER TO SUCH STOCKHOLDER. IN ADDITION, NO INFORMATION IS
PROVIDED HEREIN WITH RESPECT TO THE TAX CONSEQUENCES OF THE MERGER UNDER
APPLICABLE FOREIGN, STATE OR LOCAL LAWS. CONSEQUENTLY, EACH PULSE STOCKHOLDER
IS ADVISED TO CONSULT A TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES OF THE
MERGER TO THAT STOCKHOLDER.
 
  General. It is intended that (i) the Merger will qualify as a reorganization
under Section 368(a) of the Internal Revenue Code of 1986, as amended (the
"Code"), (ii) for Federal income tax purposes, no gain or loss will be
recognized by Pulse, Technitrol or Teco Sub and (iii) the exchange by Pulse
stockholders of their shares of Pulse Common Stock for shares of Technitrol
Common Stock or cash will have the tax treatment set forth below.
 
  Neither Pulse nor Technitrol has requested or will request an advance ruling
from the Internal Revenue Service (the "IRS") as to the tax consequences of
the Merger. However, consummation of the Merger is conditioned upon the
receipt by Pulse of a tax opinion of Pillsbury Madison & Sutro and the receipt
by Technitrol of a tax opinion of Stradley, Ronon, Stevens & Young
(collectively, the "Tax Opinions"), each dated immediately prior to the
Effective Time and to the effect that the Merger will be treated as a
reorganization within the meaning of Section 368(a) of the Code, that Pulse
and Technitrol will each be a party to the reorganization pursuant to Section
368(b) of the Code, that neither Pulse nor Technitrol will recognize any
income, gain or loss as a result of the Merger. The Tax Opinions will be
based, among other things, on customary assumptions relating to certain facts
and circumstances of, and the intentions of the parties to, the Merger, which
assumptions will have been made with the consent of Pulse and Technitrol. The
opinions of Stradley, Ronon, Stevens & Young as to certain tax consequences
concerning Pulse stockholders described below are based, among other things,
on assumptions relating to certain facts and circumstances of, and the
intentions of the parties to, the Merger, which assumptions will have been
made with the consent of Pulse and Technitrol.
 
  Exchange of Pulse Common Stock Solely for Technitrol Common Stock. In the
opinion of Stradley, Ronon, Stevens & Young, a U.S. Holder of Pulse Common
Stock who, pursuant to the Merger, exchanges such Pulse Common Stock solely
for Technitrol Common Stock (except for cash in lieu of fractional shares,
discussed below) will not recognize any gain or loss upon such exchange for
Federal income tax purposes. The tax basis of such Technitrol Common Stock
will equal (except for the basis attributable to any fractional shares of
Technitrol Common Stock, discussed below) the U.S. Holder's tax basis in the
Pulse Common Stock surrendered. Provided the Pulse Common Stock so surrendered
was held as a capital asset at the time of the exchange, the holding period of
the Technitrol Common Stock received will include the holding period of the
Pulse Common Stock. Pulse stockholders should consult their own tax advisors
as to the determination of their tax basis and holding period in any one share
of Pulse Common Stock, as several methods of determination may be available.
 
  Exchange of Pulse Common Stock Solely for Cash. In the opinion of Stradley,
Ronon, Stevens & Young, a U.S. Holder of Pulse Common Stock who, pursuant to
the Merger, exchanges such Pulse Common Stock solely for cash should recognize
a gain or loss for Federal income tax purposes equal to the difference between
the cash received and the U.S. Holder's tax basis in the Pulse Common Stock.
Assuming such U.S. Holder of Pulse Common Stock, at the time of the exchange,
held the Pulse Common Stock as a capital asset, such gain or loss should be
capital gain or loss and, if so treated, will be long-term capital gain or
loss if the U.S. Holder's holding period at that time is more than one year.
The Code contains limitations on the extent to which stockholders may deduct
capital losses from ordinary income.
 
  Exchange of Pulse Common Stock for Cash and Technitrol Common Stock. The
Merger Agreement provides that Pulse stockholders are entitled, in exchange
for their shares of Pulse Common Stock, to elect to receive either all
Technitrol Common Stock (except for cash in lieu of fractional shares,
discussed below), or all cash, or to make no election; however, in certain
circumstances, a Pulse stockholder may receive both Technitrol Common Stock
and cash (other than cash in lieu of fractional shares). In the opinion of
Stradley, Ronon, Stevens & Young, if a Pulse stockholder does receive,
pursuant to the Merger, both Technitrol Common Stock and cash,
 
                                      57
<PAGE>
 
the receipt of the cash could be taxed as a dividend (as discussed below). If
so, while the Pulse stockholder would not recognize gain or loss on the shares
of Pulse Common Stock exchanged for Technitrol Common Stock and the tax basis
therein would carry over, the stockholder could recognize gain, but could not
recognize loss, on the receipt of cash in exchange for other shares of Pulse
Common Stock. Such gain might be taxed as a dividend (as discussed below),
while any disallowed loss would be included in the adjusted basis of the
Technitrol Common Stock. A Pulse stockholder's tax consequences will also
depend on whether shares of Pulse Common Stock were purchased at different
times and prices. Such a Pulse stockholder is strongly advised to consult his
or her own tax advisor with respect to the tax consequences of the Merger on
that stockholder.
 
  Possible Dividend Treatment. The constructive ownership rules of Section 318
of the Code are important in determining whether a Pulse stockholder who
receives a combination of Technitrol Common Stock and cash pursuant to the
Merger will receive capital gain or ordinary dividend treatment on any gain
recognized by that stockholder. Those rules apply in certain specified
circumstances to attribute ownership of shares of a corporation from the
stockholder actually owning the shares (whether an individual, a trust, a
partnership or a corporation) to certain members of the individual's family or
to certain individuals, trusts, partnerships or corporations in which that
stockholder has an ownership or beneficial interest, or which have an
ownership or beneficial interest in that stockholder. A stockholder is also
considered under those rules to own any shares with respect to which the
stockholder holds exercisable options.
 
  Except in the case of cash received in lieu of a fractional share (discussed
below), the determination of whether a cash payment received in the Merger has
the effect of the distribution of a dividend will be made by comparing the
proportionate interest of the stockholder after the Merger with the
proportionate interest the stockholder would have had if the stockholder had
received solely shares of Technitrol Common Stock. This comparison is made as
though Technitrol had issued in the Merger to such stockholder solely
Technitrol Common Stock and, in a hypothetical redemption under the rules of
Section 302 of the Code, Technitrol had redeemed such portion of the
Technitrol Common Stock as represented in value, at the time of the Merger,
the amount of cash the stockholder received. In making this comparison, the
constructive ownership rules of the Code apply. The amount of any such
dividend, so determined, is limited to that stockholder's ratable share of the
accumulated earnings and profits of Pulse at the Effective Time.
 
  Under IRS guidelines, a hypothetical redemption involving a minority Pulse
stockholder whose relative stock interest in Pulse is minimal, who exercises
no control over the affairs of Pulse and who experiences, pursuant to the
Merger, a reduction in the stockholder's proportionate stock interest will not
receive dividend treatment of the cash received in these circumstances under
rules of Section 302(b)(1) of the Code. Because the determination of whether a
cash payment will be treated as having the effect of the distribution of a
dividend generally will depend in part upon the facts and circumstances of
each Pulse stockholder (e.g., whether or not such stockholder also owns any
Technitrol Common Stock), such stockholders are strongly advised to consult
their own tax advisors regarding the tax treatment of cash received in the
Merger.
 
  Cash in Lieu of Fractional Shares. No fractional shares of Technitrol Common
Stock will be issued pursuant to the Merger. Pulse stockholders who hold Pulse
Common Stock as a capital asset and who receive in the Merger, in exchange for
such stock, solely Technitrol Common Stock and cash in lieu of a fractional
share interest in Technitrol Common Stock will be treated as having received
such fraction of a share of Technitrol Common Stock and then as having
received cash in redemption by Technitrol of the fractional share interest.
Under IRS guidelines, since the cash is being distributed in lieu of
fractional shares solely for the purpose of saving Technitrol the expense and
inconvenience of issuing and transferring fractional shares, and is not
separately bargained-for consideration, the cash received will be treated as
(i) having been received in part or full payment in exchange for the
fractional share of stock redeemed, (ii) capital gain or loss and (iii) not as
a dividend.
 
  Exercise of Appraisal Rights. The transaction will be a taxable event for
Pulse stockholders who perfect appraisal rights under Delaware law and receive
solely cash in exchange for their shares. Such a stockholder should recognize
capital gain or loss, assuming that the shares are held by such stockholder as
a capital asset at
 
                                      58
<PAGE>
 
the Effective Time, equal to the difference between the amount of cash
received and the stockholder's tax basis in the shares surrendered.
 
  Backup Withholding. Unless an exemption applies, the Exchange Agent will be
required to withhold, and will withhold, 31% of any cash payments to which a
Pulse stockholder or other payee is entitled pursuant to the Merger, unless
the stockholder or other payee provides his, her or its tax identification
number (i.e., a social security number or employer identification number) and
certifies that such number is correct. Each Pulse stockholder and, if
applicable, each other payee is required to complete and sign the Substitute
Form W-9 that will be included as part of the letter of transmittal to avoid
backup withholding (or a Form W-8 if the stockholder is a nonresident alien or
foreign entity), unless an applicable exemption exists and is substantiated in
a manner satisfactory to Technitrol and the Exchange Agent.
 
  THE DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY. IT
DOES NOT ADDRESS THE STATE, LOCAL OR FOREIGN TAX ASPECTS OF THE MERGER. SINCE
THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO PULSE STOCKHOLDERS
DEPEND, TO A GREAT EXTENT, ON WHETHER THEY RECEIVE TECHNITROL COMMON STOCK OR
CASH IN EXCHANGE FOR THEIR SHARES, IT IS IMPORTANT THAT EACH PULSE STOCKHOLDER
RETURN THE ELECTION FORM SO THAT IT IS RECEIVED BEFORE THE ELECTION DEADLINE.
BECAUSE EACH STOCKHOLDER'S TAX CIRCUMSTANCES MAY DIFFER, EACH STOCKHOLDER IS
URGED TO CONSULT HIS OR HER OWN TAX ADVISOR CONCERNING THE SPECIFIC TAX
CONSEQUENCES OF THE MERGER TO SUCH STOCKHOLDER, INCLUDING THE APPLICABILITY
AND EFFECT OF STATE, LOCAL AND OTHER TAX LAWS AND ANY PROPOSED CHANGES IN SUCH
TAX LAWS.
 
ACCOUNTING TREATMENT
 
  The Merger will be accounted for by Technitrol under the "purchase" method
of accounting in accordance with generally accepted accounting principles.
Therefore, the aggregate Merger Consideration paid by Technitrol will be
allocated to Pulse's assets based on their fair value and the results of
operations of Pulse will be included in the results of operations of
Technitrol only for the period subsequent to the Effective Time.
 
AFFILIATE AGREEMENTS
 
  Prior to the Effective Time, certain persons who may be deemed to be
"affiliates" (as the term is defined for purposes of Rule 145 promulgated
under the Securities Act) of Pulse will enter into certain affiliate
agreements ("Affiliate Agreements") so as to comply with Rule 145 and federal
income tax regulations applicable to reorganizations. Specifically, each such
person will agree to make a Stock Election and further will agree not to sell,
dispose of or enter into any other transaction in order to reduce, directly or
indirectly, such person's risk of investment with respect to any shares of
Technitrol Common Stock received by such person in connection with the Merger.
Each such person will also agree not to sell, transfer or otherwise dispose of
Technitrol Common Stock issued to such person in the Merger unless such
disposition is made in conformity with Rule 145(d) of the Securities Act or
such person delivers to Technitrol a legal opinion to the effect that such
disposition is otherwise exempt from registration under the Securities Act.
 
                              TERMS OF THE MERGER
 
EFFECTIVE TIME
 
  The Merger will become effective at the Effective Time (i.e., upon the
filing of a certificate with the Secretary of State of the State of Delaware
in accordance with the DGCL). It is anticipated that if the Merger Agreement
is approved at the Special Meetings of Technitrol and Pulse and all other
conditions of the Merger have been fulfilled or waived, the Effective Time
will occur on or about September 29, 1995, or on a date as soon as practicable
thereafter.

CONVERSION OF SHARES OF PULSE COMMON STOCK; ELECTION
 
  Each share of Pulse Common Stock issued and outstanding immediately prior to
the Effective Time (excluding any shares held by Pulse as treasury shares and
Dissenters' Shares) shall be converted into the right to receive (i) shares of
Technitrol Common Stock equal to the Exchange Ratio (initially .5812 shares),
(ii) the Per Share Cash Amount (i.e., $8.50 in cash), or (iii) a combination
of shares of Technitrol Common Stock and cash as described below. The Exchange
Ratio is subject to adjustment as follows:
 
    (A) If the Average Closing Price (the average closing price of Technitrol
  Common Stock on the ASE as reported in The Wall Street Journal for the ten
  (10) trading days immediately preceding the three (3) business days
  preceding the Effective Time) is less than $13 3/4, then (x) the Exchange
  Ratio shall be adjusted upward to that ratio which yields, based upon the
  Average Closing Price, $8.00 per share of Pulse Common Stock and (y) the
  Per Share Cash Amount shall remain unchanged; or
 
    (B) If the Average Closing Price is greater than $16 3/8, then (x) the
  Exchange Ratio shall be adjusted downward to that ratio which yields, based
  upon the Average Closing Price, $9.52 per share of Pulse Common Stock and
  (y) the Per Share Cash Amount shall remain unchanged.
 
  Subject to the allocation procedures set forth below, each record holder of
shares of Pulse Common Stock will be entitled (i) to make a Cash Election
(i.e., to elect to receive cash for all such shares), (ii) to make a Stock
Election (i.e., to elect to receive Technitrol Common Stock for all of such
shares), or (iii) to indicate a Non-Election (i.e., to indicate that such
holder has no preference as to the receipt of cash or Technitrol Common Stock
for such shares). All such elections are to be made on a Form of Election.
Holders of record of shares of Pulse Common Stock who hold such shares as a
Representative (e.g., as a nominee, trustee or in other representative
capacity) may submit multiple Forms of Election, provided that any such
Representative certifies that each such Form of Election covers all the shares
of Pulse Common Stock held by such Representative for a particular beneficial
owner. All elections will be revocable until 5:00 p.m. New York City time on
the last business day prior to the Effective Time. A Non-Election shall be
deemed to have been made by shares as to which a valid and timely Form of
Election is not received.
 
  If the Cash Election Shares (the aggregate number of shares of Pulse Common
Stock as to which valid elections to receive cash have been made) exceeds the
Cash Election Number (fifty percent (50%) of the shares of Pulse Common Stock
outstanding immediately prior to the Effective Time), all the Stock Election
Shares (shares of Pulse Common Stock covered by Stock Elections) and all the
Non-Election Shares (shares of Pulse Common Stock covered by Non-Elections)
shall be converted into the right to receive Technitrol Common Stock, and the
Cash Election Shares shall be converted into the right to receive Technitrol
Common Stock and cash in the following manner:
 
  each Cash Election Share shall be converted into the right to receive (i)
  an amount in cash, without interest, equal to the product of (x) the Per
  Share Cash Amount and (y) the Cash Fraction (a fraction, the numerator of
  which shall be the Cash Election Number and the denominator of which shall
  be the total number of Cash Election Shares), and (ii) a number of shares
  of Technitrol Common Stock equal to the product of (x) the Exchange Ratio
  and (y) a fraction equal to one minus the Cash Fraction.
 
  For example, if 75% of the outstanding shares of Pulse Common Stock elect
cash, then all holders of Stock Election Shares and Non-Election Shares would
receive Technitrol Common Stock in exchange for their shares of Pulse Common
Stock based on the Adjusted Exchange Ratio. The Cash Election Shares would be
exchanged for a combination of Technitrol Common Stock and cash based upon a
Cash Fraction determined by dividing the Cash Election Number (50%) by the
Cash Election Shares (75%) or two-thirds ( 2/3). Accordingly, a hypothetical
Pulse stockholder holding 1,000 shares for which a Cash Election is made would
be entitled to receive the following (assuming the Adjusted Exchange Ratio is
 .5812):
 
    (1) $5,666.67 in cash (the product of (i) the Per Share Cash Amount of
  $8.50, (ii) the Cash Fraction ( 2/3) and (iii) the number of shares at
  issue (1,000)); and
 
                                      60
<PAGE>
 
    (2) 193.73 shares of Technitrol Common Stock (the product of (i) the
  Exchange Ratio of .5812, (ii) a fraction equal to one minus the Cash
  Fraction ( 1/3) and (iii) the number of shares at issue (1,000)), except
  that the stockholder would actually receive 193 shares and cash in lieu of
  the fractional share (cash equal to the product of the Average Closing
  Price and .73).
 
  If the aggregate number of Stock Election Shares exceeds fifty-five percent
(55%) of the shares of Pulse Common Stock outstanding immediately prior to the
Effective Time (the "Stock Election Number"), all Cash Election Shares and
Non-Election Shares shall be converted into the right to receive cash, and all
Stock Election Shares shall be converted into the right to receive Technitrol
Common Stock and cash in the following manner:
 
  each Stock Election Share shall be converted into the right to receive (i)
  a number of shares of Technitrol Common Stock equal to the product of (x)
  the Exchange Ratio and (y) the Stock Fraction (a fraction, the numerator of
  which shall be the Stock Election Number and the denominator of which shall
  be the total number of Stock Election Shares), and (ii) an amount in cash,
  without interest, equal to the product of (x) the Per Share Cash Amount and
  (y) a fraction equal to one minus the Stock Fraction.
 
  For example, if 75% of the outstanding shares of Pulse Common Stock elect
Technitrol Common Stock, then all Cash Election Shares and Non-Election Shares
would receive cash of $8.50 per share in exchange for their shares of Pulse
Common Stock. The Stock Election Shares would be exchanged for a combination
of Technitrol Common Stock and cash based upon a Stock Fraction determined by
dividing the Stock Election Number (55%) by the Stock Election Shares (75%) or
eleven-fifteenths ( 11/15). Accordingly, a hypothetical Pulse stockholder
holding 1,000 shares for which a Stock Election is made would be entitled to
receive the following (assuming the Adjusted Exchange Ratio is .5812):
 
      (1) 426.21 shares of Technitrol Common Stock (the product of (i) the
    Exchange Ratio of .5812, (ii) the Stock Fraction ( 11/15) and (iii) the
    number of shares at issue (1,000)), except that the stockholder would
    actually receive 426 shares and cash in lieu of the fractional share;
    and
 
      (2) $2,266.67 in cash (the product of (i) the Per Share Cash Amount of
    $8.50, (ii) a fraction equal to one minus the Stock Fraction ( 4/15) and
    (iii) the number of shares at issue (1,000)).
 
  In the event that the number of Cash Election Shares does not exceed the
Cash Election Number and the number of Stock Election Shares does not exceed
the Stock Election Number, all Cash Election Shares shall be converted into
the right to receive cash, all Stock Election Shares shall be converted into
the right to receive Technitrol Common Stock, and the Non-Election Shares, if
any, shall be converted into the right to receive Technitrol Common Stock and
cash in the following manner:
 
  each Non-Election Share shall be converted into the right to receive (i) a
  number of shares of Technitrol Common Stock equal to the product of (x) the
  Exchange Ratio and (y) the Non-Election Fraction (a fraction, which is the
  lesser of one (1) or a fraction where the numerator shall be the excess of
  the Stock Election Number over the total number of Stock Election Shares
  and the denominator of which shall be the aggregate of the Non-Election
  Shares) and (ii) an amount in cash, without interest, equal to the product
  of (x) the Per Share Cash Amount and (y) a fraction equal to one minus the
  Non-Election Fraction.
 
  For example, if 20% of the outstanding shares of Pulse Common Stock elect
cash, 30% elect Technitrol Common Stock and 50% are deemed to have made Non-
Elections, then all holders of Cash Election Shares would receive cash of
$8.50 per share in exchange for their shares of Pulse Common Stock, all
holders of Stock Election Shares would receive Technitrol Common Stock, and
all holders of Non-Election Shares would receive a combination of Technitrol
Common Stock and cash based upon a Non-Election Fraction calculated by
dividing (i) the excess of the Stock Election Number over the Stock Election
Shares (55%-30%) by the Non-Election Shares (50%) or one-half ( 1/2).
Accordingly, a hypothetical Pulse stockholder holding 1,000 shares for which a
Non-Election was made would be entitled to receive the following (assuming the
Adjusted Exchange Ratio is .5812):
 
      (1) 290.6 shares of Technitrol Common Stock (the product of (i) the
    Exchange Ratio of .5812, (ii) the Non-Election Fraction ( 1/2) and (iii)
    the number of shares at issue (1,000), except that the stockholder would
    actually receive 290 shares and cash in lieu of the fractional share;
    and
 
                                      61
<PAGE>
 
      (2) $4,250 in cash (the product of (i) the Per Share Cash Amount of
    $8.50, (ii) a fraction equal to one minus the Non-Election Fraction (
    1/2) and (iii) the number of shares at issue (1,000)).
 
  If the tax opinions of counsel to Technitrol and Pulse, respectively,
receipt of which is a condition to each party's obligation to consummate the
Merger (see "TERMS OF THE MERGER--Conditions to the Merger"), cannot be
delivered as a result of insufficient continuity of interest, then the Stock
Election Number shall be increased, and the Cash Election Number
correspondingly decreased (if necessary), to the minimum extent necessary to
enable such counsel to deliver the tax opinions.
 
  A FORM OF ELECTION FOR USE BY PULSE STOCKHOLDERS IN THEIR ELECTION TO
RECEIVE EITHER CASH OR TECHNITROL COMMON STOCK IN EXCHANGE FOR THEIR SHARES OF
PULSE COMMON STOCK IS INCLUDED HEREWITH TO STOCKHOLDERS OF RECORD AS OF THE
RECORD DATE. To be effective, a Form of Election must be properly completed,
signed and submitted to Registrar and Transfer Company, as exchange agent (the
"Exchange Agent"), accompanied by all stock certificates representing shares
of Pulse Common Stock held by the person submitting such Form of Election (or
by a guarantee of delivery of such certificates in the form set forth in the
Form of Election by a member of any registered national securities exchange, a
member of the National Association of Securities Dealers, Inc. or a commercial
bank or trust company having an office or correspondent in the United States,
provided such certificates are in fact delivered to the Exchange Agent within
four (4) business days as set forth in such guarantee of delivery (a
"Guaranteed Delivery")) and must be received by the Exchange Agent no later
than 5:00 p.m. New York City time on the day one business day prior to the
Effective Time. Until such time, all elections will be revocable. PULSE
STOCKHOLDERS WHO FAIL TO RETURN A FORM OF ELECTION, SUBMIT AN IMPROPERLY
COMPLETED FORM OF ELECTION, OR FAIL TO SUBMIT THEIR STOCK CERTIFICATES WITH
THEIR FORM OF ELECTION (OR FAIL TO PROVIDE FOR, AND COMPLY WITH THE
REQUIREMENTS OF, GUARANTEED DELIVERY), WILL BE DEEMED TO HAVE MADE A NON-
ELECTION. The Merger Agreement provides that Technitrol and Pulse will cause
the Effective Time to occur as promptly as practicable after approval and
adoption by the shareholders of Technitrol and the stockholders of Pulse of
the Merger Agreement and the satisfaction (or waiver, if permissible) of the
other conditions to the effectiveness of the Merger set forth in the Merger
Agreement. It is anticipated that the Effective Time will occur on or about
September 29, 1995, or on a date as soon as practicable thereafter. Thus,
stockholders of Pulse are urged to deliver a properly completed Form of
Election together with the applicable stock certificates (or provide for
Guaranteed Delivery) to the Exchange Agent no later than 5:00 p.m., New York
City time, on September 28, 1995, in order to assure that their Form of
Election will be received prior to the Effective Time. Persons who become
stockholders of Pulse after the Pulse Record Date or any other stockholders
who need a Form of Election may obtain copies of the Form of Election upon
request from the Exchange Agent either in writing at 10 Commerce Drive,
Cranford, New Jersey, 07016 or by telephone at (908) 272-8511. Technitrol and
Pulse will each use its best efforts to mail or cause to be mailed to all
persons who become holders of Pulse Common Stock between the Pulse Record Date
and the day seven (7) days prior to the anticipated Effective Time a Form of
Election and will make available a Form of Election to all persons who become
stockholders of Pulse after that date.
 
PROCEDURES FOR EXCHANGE OF CERTIFICATES
 
  PULSE STOCKHOLDERS THAT WISH TO SUBMIT A FORM OF ELECTION SHOULD DELIVER
THEIR STOCK CERTIFICATES TOGETHER WITH SUCH FORM OF ELECTION OR PROVIDE FOR,
AND COMPLY WITH THE REQUIREMENTS OF, GUARANTEED DELIVERY.
 
  If a Pulse stockholder does not submit such holder's stock certificates with
a properly completed Form of Election (or provide for, and comply with the
requirements of, Guaranteed Delivery) by 5:00 p.m. New York City time on the
day one business day prior to the Effective Time, as soon as reasonably
practicable after the Effective Time Technitrol will instruct the Exchange
Agent to mail to each such holder of record (other than owners of Dissenters'
Shares) of a certificate or certificates which immediately prior to the
Effective Time
 
                                      62
<PAGE>
 
represented outstanding shares of Pulse Common Stock (such certificates,
together with certificates delivered with a Form of Election, the
"Certificates") (i) a letter of transmittal and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for certificates
representing Technitrol Common Stock or cash. After the Effective Time,
stockholders who have surrendered a Certificate for cancellation to the
Exchange Agent together with such letter of transmittal, duly executed, and
such other documents as may be required pursuant to such instructions, or
submitted a Certificate with a Form of Election, shall be entitled to receive
in exchange for such Certificate (i) a certificate representing that number of
whole shares of Technitrol Common Stock which such holder has the right to
receive in respect of the shares of Pulse Common Stock formerly represented by
such Certificate, (ii) cash to which such holder is entitled, (iii) cash in
lieu of fractional shares of Technitrol Common Stock and (iv) any dividends or
other distributions to which such holder is entitled as described below
(collectively, clauses (i) to (iv) are herein referred to as the "Merger
Consideration"), and the Certificate so surrendered shall forthwith be
canceled. In the event of a transfer of ownership of shares of Pulse Common
Stock which is not registered in the transfer records of Pulse, a certificate
representing the proper number of shares of Technitrol Common Stock and/or
cash may be issued and/or paid to a transferee if the Certificate representing
such shares of Pulse Common Stock is presented to the Exchange Agent,
accompanied by all documents required to evidence and effect such transfer and
by evidence that any applicable stock transfer taxes have been paid. Until
surrendered, each Certificate shall be deemed at any time after the Effective
Time to represent only the right to receive upon such surrender the Merger
Consideration.
 
  At or prior to the Effective Time, Technitrol will deposit or cause to be
deposited with the Exchange Agent appropriate amounts of shares of Technitrol
Common Stock and cash to comprise the Merger Consideration. Because Guaranteed
Delivery permits the delivery of stock certificates up to three (3) business
days after the Effective Time, the Merger Consideration will not be
distributed until at least three (3) business days after the Effective Time.
 
  No dividends or other distributions declared or made after the Effective
Time with respect to shares of Technitrol Common Stock with a record date
after the Effective Time shall be paid to the holder of any unsurrendered
Certificate with respect to the shares of Technitrol Common Stock represented
thereby, and no cash payment or cash payment in lieu of fractional shares of
Technitrol Common Stock shall be paid to any such holder, until the holder of
such Certificate shall surrender such Certificate. Subject to the effect of
applicable laws, following surrender of any such Certificate, there shall be
paid to the holder of the certificates representing whole shares of Technitrol
Common Stock issued in exchange therefor, without interest, (i) promptly, the
amount of any cash payable with respect to a fractional share of Technitrol
Common Stock to which such holder is entitled and the amount of dividends or
other distributions with a record date after the Effective Time theretofore
paid with respect to such whole shares of Technitrol Common Stock and (ii) at
the appropriate payment date, the amount of dividends or other distributions
with a record date after the Effective Time but prior to surrender and a
payment date occurring after surrender, payable with respect to such whole
shares of Technitrol Common Stock. All shares of Technitrol Common Stock
issued upon conversion of the shares of Pulse Common Stock (plus any cash paid
for fractional shares) shall be deemed to have been issued (and paid) in full
satisfaction of all rights pertaining to such shares of Pulse Common Stock. No
interest will be paid on the Merger Consideration.
 
  Neither Technitrol nor Teco Sub will be liable to any holder of shares of
Pulse Common Stock for any shares of Technitrol Common Stock (or dividends or
distributions with respect thereto) or cash in respect of shares of Pulse
Common Stock or in lieu of fractional shares of Technitrol Common Stock
delivered to a public official pursuant to any abandoned property, escheat or
similar law.
 
  No certificates or scrip representing fractional shares of Technitrol Common
Stock will be issued upon surrender for exchange of Certificates, and such
fractional share interests will not entitle the owner thereof to vote or to
any rights of a stockholder of Technitrol. In lieu of any such fractional
shares, each holder of Pulse Common Stock shall be paid an amount in cash
(without interest), rounded to the nearest cent, determined by multiplying (i)
the Average Closing Price by (ii) the fractional interest to which such holder
would otherwise be
 
                                      63
<PAGE>
 
entitled (after taking into account all shares of Pulse Common Stock then held
of record by such holder). As soon as practicable after the determination of
the amount of cash, if any, to be paid to holders of Pulse Common Stock with
respect to any fractional share interests, the Exchange Agent shall promptly
pay such amounts to such holders of Pulse Common Stock.
 
  After the Effective Time, there will be no transfers on the stock transfer
books of Pulse of the shares of Pulse Common Stock.
 
PULSE STOCK OPTIONS
 
  As of August 11, 1995, there were outstanding options to purchase 455,364
shares of Pulse Common Stock, warrants to purchase 43,567 shares of Pulse
Common Stock and warrants to purchase 655,489 shares of Pulse Class B Stock.
At the Effective Time, each then outstanding option to purchase shares of
Pulse Common Stock will be assumed by Technitrol (the "Assumed Options")
without any action on the part of a holder of any Assumed Options. All of such
Assumed Options will continue to have, and be subject to, the same terms and
conditions set forth in the applicable Pulse stock option agreements, except
that following the Effective Time, (a) each Assumed Option will be exercisable
to purchase the number of whole shares of Technitrol Common Stock determined
by multiplying the number of shares of Pulse Common Stock purchasable under
such option immediately prior to the Effective Time by the Adjusted Exchange
Ratio, rounded up to the nearest whole number, and (b) the per share exercise
price of the Assumed Option will be equal to the per share exercise price of
the specific Assumed Option, divided by the Adjusted Exchange Ratio, rounded
down to the nearest whole cent. After the Effective Time, Technitrol will
issue to each holder of an Assumed Option a document evidencing the assumption
by Technitrol of such option. OPTION AGREEMENTS NEED NOT BE SURRENDERED BY
HOLDERS OF ASSUMED OPTIONS.
 
  As promptly as practicable after the Effective Time, Technitrol will file a
registration statement under the Securities Act covering the shares of
Technitrol Common Stock issuable upon exercise of the Assumed Options.
 
  Certain of the applicable Pulse stock option agreements, as well as the
employee benefit plans to which such agreements relate, provide that an event
such as the Merger shall cause the underlying options to terminate upon the
effectiveness of such event (e.g., at the Effective Time); however, prior to
any such termination the exercisability of the options is accelerated (i.e.,
the options become exercisable in full, whether or not then otherwise
exercisable or "vested"). Technitrol and Pulse have agreed, subject to
approval and adoption of the Merger Agreement by the stockholders of Pulse, to
amend such Pulse stock option agreements and the employee benefit plans to
which these agreements relate to prevent the event of the Merger from
terminating any options which would otherwise become Assumed Options.
 
  By their approval and adoption of the Merger Agreement, the stockholders of
Pulse will be deemed to have approved the foregoing amendments to the Pulse
stock option agreements at issue and the employee benefit plans to which such
agreements relate.
 
  At the Effective Time, each then outstanding warrant to acquire Pulse Common
Stock shall remain outstanding, although such warrants shall thereafter be
exercisable for shares of Technitrol Common Stock as adjusted pursuant to the
terms of the warrants. However, the warrant to acquire 655,489 shares of Pulse
Class B Stock, which is held by Technitrol (see "CERTAIN TRANSACTIONS--
Technitrol Purchase of Outstanding Warrant") is expected to be canceled.
 
CONDUCT OF PULSE'S AND TECHNITROL'S BUSINESSES PRIOR TO THE MERGER
 
  Under the Merger Agreement, Pulse has agreed that, during the period from
the date of the Merger Agreement up to the Effective Time (unless the Merger
Agreement is terminated), except to the extent that Technitrol otherwise
consents, Pulse will carry on its business in the usual and ordinary course in
substantially the same manner as previously conducted, pay its debts and taxes
when due (subject to good faith disputes over
 
                                      64
<PAGE>
 
such debts or taxes), pay or perform other material obligations when due, and
use all reasonable efforts consistent with past practices and policies to
preserve intact Pulse's present business organization, keep available the
services of its present officers and employees and preserve its relationships
with customers, suppliers, distributors, licensors, licensees and others
having business dealings with Pulse, to the end that Pulse's goodwill and
ongoing businesses will be unimpaired at the Effective Time. Pulse has
specifically agreed that it will not, without the prior written consent of
Technitrol, which consent shall not be unreasonably withheld or delayed: (a)
enter into or amend any agreement or take any action which reasonably would be
expected to have a material adverse effect on Pulse; (b) enter into, amend or
terminate certain types of agreements, plans or arrangements; (c) transfer or
license or otherwise extend, amend or modify any rights to Pulse's
intellectual property rights; (d) grant any severance or termination pay to
any executive officer or to any other employee except payments made in
connection with the termination of employees who are not executive officers in
amounts consistent with Pulse's policies and past practices or pursuant to
existing written agreements or policies as previously disclosed to Technitrol
or pursuant to written agreements consistent with Pulse's past agreements
under similar circumstances; (e) adopt or amend any employee benefit or stock
purchase or option plan, or enter into any employment contract, pay any
special bonus or special remuneration to any director or employee, or increase
the salaries or wage rates of its employees other than in the ordinary course
of business, consistent with past practice; (f) accelerate, amend or change
the period of exercisability of options or restricted stock, or reprice
options granted under the employee stock plans or authorize cash payments in
exchange for any options granted under any of such plans; (g) commence any
litigation other than for the routine collection of bills, or where Pulse in
good faith determines that failure to commence suit would result in the
material impairment of a valuable aspect of Pulse's business (provided that
Pulse consults with Technitrol prior to the filing of such suit); (h) declare
or pay any dividends on or make any other distributions (whether in cash,
stock or property) in respect of its capital stock, or split, combine or
reclassify its capital stock or issue or authorize the issuance of any other
securities in respect of, in lieu of or in substitution for shares of capital
stock of Pulse; (i) repurchase or otherwise acquire, directly or indirectly,
any shares of its capital stock; (j) issue, deliver or sell or authorize the
issuance, delivery or sale of, any shares of its capital stock of any class or
securities convertible into, or subscriptions, rights, warrants or options to
acquire, or enter into other agreements or commitments of any character
obligating it to issue, any such shares or other convertible securities, other
than the issuance of shares of Pulse Common Stock pursuant to outstanding
stock options, Pulse's Employee Stock Purchase Plan, and outstanding warrants;
(k), cause, permit or propose any amendments to the Pulse Certificate of
Incorporation or Pulse's Bylaws; (l) acquire or agree to acquire by merging or
consolidating with, or by purchasing any equity interest in or a material
portion of the assets of, or by any other manner, any business or any
corporation, partnership interest, association or other business, organization
or division thereof, or otherwise acquire or agree to acquire any assets which
are material, individually or in the aggregate, to the business of Pulse,
except for inventory and supplies acquired in the ordinary course of business
consistent with past practices; (m) sell, lease, license, encumber or
otherwise dispose of any of Pulse's properties or assets which are material,
individually or in the aggregate, to the business of Pulse, except in the
ordinary course of business consistent with past practice; (n) incur any
indebtedness for borrowed money (other than pursuant to existing credit
facilities in the ordinary course of business) or guarantee any indebtedness
or issue or sell any debt securities or warrants or rights to acquire debt
securities of Pulse; (o) revalue any of Pulse's assets; or (p) take any of
certain other specific actions, or any action which would cause or would be
reasonably likely to cause any of the conditions to the Merger set forth in
the Merger Agreement not to be satisfied.
 
  Under the Merger Agreement, Technitrol has agreed, during the period from
the date of the Merger Agreement up to the Effective Time (unless the Merger
Agreement is terminated) not to do any of the following without the prior
written consent of Pulse, which consent shall not be unreasonably withheld or
delayed: (a) enter into or amend any agreement or take any action which
reasonably would be expected to have a material adverse effect on Technitrol;
(b) except as is consistent with past practices, declare or pay any dividends
on any of its capital stock; (c) split, combine or reclassify any of its
capital stock or issue or authorize the issuance of any other securities in
respect of, in lieu of or in substitution for shares of capital stock of
Technitrol; (d) repurchase or otherwise acquire, directly or indirectly, any
shares of its capital stock, except pursuant to existing plans under Rule 10b-
18 of the Exchange Act or Technitrol's Restricted Stock Plan; (e) issue,
deliver or sell or authorize or
 
                                      65
<PAGE>
 
propose the issuance, delivery or sale of any shares of its capital stock of
any class or securities convertible into, or subscriptions, rights, warrants
or options to acquire, or other agreements or commitments of any character
obligating it to issue, any such shares or other convertible securities, other
than the issuance of shares of Technitrol Common Stock pursuant to
Technitrol's Restricted Stock Plan in accordance with the terms of such plan
and consistent with past practice; (f) cause, permit or propose any amendments
to Technitrol's Articles of Incorporation or any material amendments to
Technitrol's bylaws (except for the Charter Amendment as to which Pulse has
given its prior written consent); (g) sell or otherwise dispose of any of
Technitrol's properties or assets which are material, individually or in the
aggregate, to the business of Technitrol, except in the ordinary course of
business; or (h) take any action which would cause or would be reasonably
likely to cause any of the conditions to the Merger set forth in the Merger
Agreement not to be satisfied.
 
CONDUCT OF THE BUSINESS OF THE COMBINED COMPANIES FOLLOWING THE MERGER
 
  Once the Merger is consummated, Pulse will cease to exist as a corporation,
and Teco Sub will succeed to all of the business, assets, and liabilities and
obligations of Pulse as a result of Pulse's merger with and into Teco Sub as
the Surviving Corporation. Teco Sub will change its name to Pulse Engineering,
Inc. ("New Pulse"). Technitrol's current intention is to operate New Pulse as
an independent entity. Technitrol does not presently plan layoffs of any
significant numbers of employees as a result of the Merger.
 
  The Board of Directors of New Pulse following the Merger will consist of
three employees of Technitrol (Messrs. Thomas J. Flakoll, Albert Thorp, III
and John L. Kowalski). No employee of Pulse has entered into employment or
consulting agreements with Technitrol or New Pulse as a result of the Merger.
 
NO SOLICITATION
 
  The Merger Agreement provides that Pulse and its subsidiaries will not, and
Pulse will use its reasonable best efforts to cause their respective
directors, officers, employees, representatives, investment bankers, agents
and affiliates not to, directly or indirectly, (i) initiate, solicit or
encourage submission of any inquiries, proposals or offers by any person,
entity or group (other than Technitrol, Teco Sub and their affiliates, agents
and representatives) relating to any Acquisition Proposal (as defined below),
or (ii) participate in any discussions or negotiations with, or disclose any
non-public information concerning Pulse or any of its subsidiaries to, or
afford any access to the properties, books or records of Pulse or any of its
subsidiaries to, or otherwise assist, facilitate or express a receptiveness
to, or enter into any agreement or understanding with, any person, entity or
group (other than Technitrol, Teco Sub and their affiliates, agents and
representatives) in connection with any Acquisition Proposal. Under the Merger
Agreement, an "Acquisition Proposal" means any proposal relating to the
possible acquisition of (i) Pulse (whether by way of merger or otherwise),
(ii) all or a substantial portion of the assets of Pulse or (iii) a
substantial portion of the equity securities of Pulse (except by conversion or
exercise of currently outstanding securities). Additionally, subject to
certain exceptions described below, Pulse and its subsidiaries will not, and
will cause their respective directors, officers, employees, representatives,
investment bankers, agents and affiliates not to, directly or indirectly, make
or authorize any statement, recommendation or solicitation in support of any
Acquisition Proposal made by any person, entity or group (other than
Technitrol and/or Teco Sub).
 
  Notwithstanding the foregoing, prior to the Effective time, Pulse may, to
the extent the Pulse Board determines in good faith, after consultation with
outside legal counsel, that the Board's fiduciary duties under applicable law
require it to do so, participate in discussions or negotiations with, and,
subject to the requirements set forth below, furnish information to any
person, entity or group after such person, entity or group shall have
delivered to Pulse in writing an unsolicited bona fide Acquisition Proposal
which the Pulse Board in its good faith reasonable judgment determines, after
consultation with all of its principal advisors in connection with the Merger,
would result in a transaction more favorable to the stockholders of Pulse than
the Merger and for which financing, to the extent required, is then committed
or which, in the good faith reasonable judgment of the Pulse Board (based upon
the advice of all its principal advisors in connection with the Merger), is
reasonably capable of being financed by such person, entity or group and which
is probable to be consummated (a "Superior
 
                                      66
<PAGE>
 
Proposal"). Pulse may furnish information with respect to a Superior Proposal
only if Pulse (i) first notifies Technitrol of the information proposed to be
disclosed, (ii) communicates to Technitrol the terms and conditions of any
Acquisition Proposal or potential Acquisition Proposal, and (iii) provides
such information pursuant to a confidentiality agreement at least as
restrictive as the confidentiality agreement entered into between Technitrol
and Pulse. In the event Pulse receives a Superior Proposal, nothing contained
in the Merger Agreement shall prevent the Pulse Board from approving such
Superior Proposal or recommending such Superior Proposal to Pulse's
stockholders if the Pulse Board determines, in good faith after consultation
with outside legal counsel, that such action is required by its fiduciary
duties under applicable law; in such case, the Board may amend or withdraw its
recommendation of the Merger.
 
BREAK-UP FEE; EXPENSES
 
  If for any reason (a) the Pulse Board accepts a Superior Proposal or
recommends a Superior Proposal to Pulse's stockholders, or (b) (i) the Pulse
Board adversely amends, withholds or withdraws its recommendation that Pulse's
stockholders approve the Merger, (ii) the stockholders of Pulse fail to
approve the Merger prior to September 30, 1995, or (iii) there are Dissenters'
Shares representing 15% or more of the shares of Pulse Common Stock
outstanding on the Pulse Record Date, and within nine months following the
occurrence of an event set forth in any of clauses (i), (ii) or (iii) above,
Pulse merges with another individual, corporation, partnership, trust or other
entity, including any group of the foregoing acting in concert (in any such
event, a "Person"), issues stock representing a 40% or greater voting interest
in Pulse to another Person, transfers more than 50% of its assets to another
Person or enters into an option, agreement or letter of intent to do any of
the foregoing or any other arrangement intended to transfer Pulse or control
of Pulse to such other Person, or the stockholders of Pulse, in response to a
tender offer or exchange offer by any Person tender shares representing a 40%
or greater voting interest in Pulse or give options or rights to any Person to
acquire such shares, then, provided Technitrol shall not have materially
breached any of the representations, warranties, covenants or agreements made
on its part under the Merger Agreement, Pulse shall pay to Technitrol, within
five business days following Technitrol's written request therefor, a break-up
fee of $2 million.
 
  In addition to the provisions regarding a break-up fee described above, the
Merger Agreement contains provisions under which Technitrol or Pulse may be
required to reimburse the other for expenses incurred in connection with the
proposed Merger. If the Merger Agreement is terminated by Technitrol as a
result of Pulse's breach of any representation, warranty, covenant or
agreement in the Merger Agreement, then Pulse will be required to pay
Technitrol for all of its reasonable out-of-pocket expenses, including but not
limited to attorneys' fees, accounting fees, financial printer expenses,
filing fees and fees and expenses of financial advisors incurred in connection
with the Merger Agreement and the Merger ("Out-of-Pocket Expenses"), not to
exceed $1,000,000. If the Merger Agreement is terminated by Pulse as a result
of Technitrol's breach of any representation, warranty, covenant or agreement
in the Merger Agreement, then Technitrol shall pay Pulse's Out-of-Pocket
Expenses not to exceed $1,000,000, incurred in connection with the Merger
Agreement and the Merger. If (i) the Pulse Board adversely amends, withholds
or withdraws its recommendation of the Merger or (ii) Pulse's stockholders do
not approve the Merger at the Pulse Special Meeting, then, provided that
Technitrol is not then in material breach of the terms of the Merger
Agreement, Pulse shall pay Technitrol's Out-of-Pocket Expenses, not to exceed
$1,000,000, upon written request therefor; provided, however, that any amounts
paid to Technitrol in the event of clause (i) or (ii) shall reduce, on a
dollar-for-dollar basis, the amount, if any, of the break-up fee described in
the preceding paragraph. If (i) the Technitrol Board adversely amends,
withholds or withdraws its recommendation of the Merger or (ii) Technitrol's
shareholders do not approve the Merger at the Technitrol Special Meeting,
then, provided that Pulse is not then in material breach of the terms of the
Merger Agreement, Technitrol shall pay Pulse's Out-of-Pocket Expenses, not to
exceed $1,000,000, upon written request therefor.
 
  Other than the fees and expenses described above, and the fees incurred in
connection with the printing and filing of the Registration Statement which
will be shared equally by Technitrol and Pulse, each of Technitrol and Pulse
will pay their own fees and expenses incurred in connection with the Merger.

abandoned at any time prior to the Effective Time (a) by mutual written
consent of Technitrol and Pulse; (b) by Technitrol or Pulse if it is not in
material breach of its obligations under the Merger Agreement and there has

       PROPOSAL TO INCREASE AUTHORIZED SHARES OF TECHNITROL COMMON STOCK
 
PROPOSED AMENDMENT
 
  On May 23, 1995, the Technitrol Board approved an amendment to Technitrol's
Articles of Incorporation (the "Charter"), subject to approval by Technitrol's
shareholders, that would increase the number of authorized shares of
Technitrol Common Stock from 10 million shares to 30 million shares. If
approved by Technitrol's shareholders, Article FIFTH of the Charter will be
amended and restated in its entirety to read as follows:
 
    FIFTH: The aggregate number of shares which the corporation shall have
  the authority to issue is 30 million shares of Common Stock; the par value
  of said Common Stock shall be $.125 per share.
 
  This proposal is being made so that there are after the issuance of the
shares of Technitrol Common Stock in conjunction with the Merger (i) adequate
shares of Technitrol Common Stock authorized for issuance in connection with
the continuation of Technitrol's Restricted Stock Plan; (ii) an adequate
number of shares of Technitrol Common Stock available for issuance upon
exercise of the Assumed Options; and (iii) a sufficient number of additional
authorized shares of Technitrol Common Stock available for issuance in the
future. The Technitrol Board believes that the availability of such shares
would provide flexibility for Technitrol in meeting its possible needs by
enabling the Technitrol Board to raise additional capital through the issuance
of Technitrol Common Stock or securities convertible into, or exercisable for
Technitrol Common Stock, to declare stock dividends payable in Technitrol
Common Stock, to grant additional share awards under Technitrol's Restricted
Stock Plan, or to employ Technitrol Common Stock as a form of consideration
for acquisitions. Only approximately three million of the authorized shares of
Technitrol Common Stock are presently available for issuance. Therefore, the
Technitrol Board believes that Technitrol does not presently have a sufficient
number of authorized but unissued and unreserved shares of Technitrol Common
Stock available, and that a sufficient
 
                                      69
<PAGE>
 
number of authorized but unissued and unreserved shares may not become
available in an appropriate time frame if and when needed, to provide the
flexibility for Technitrol to meet its possible needs in the foreseeable
future through the issuance of Technitrol Common Stock. Other than for the
stock portion of the Merger Consideration and pursuant to Technitrol's
Restricted Stock Plan and the Assumed Options, Technitrol does not presently
intend to issue any additional shares for any specific purpose. There are
currently issued and outstanding 6,047,792 shares of Technitrol Common Stock.
There are presently 3,952,258 shares available for issuance in the future.
Between 1,631,790 to 1,794,969 shares of Technitrol Common Stock are expected
to be issued to holders of Pulse Common Stock as part of the Merger
Consideration. At the Effective Time, approximately 250,000 shares of
Technitrol Common Stock will be reserved for issuance upon exercise of the
Assumed Options. The Charter Amendment is being recommended to Technitrol's
shareholders at this time, rather than in connection with each specific
issuance of shares that may be proposed in the future, in order to avoid any
unnecessary delay and expense in connection with such future specific
issuances of shares because of the need for shareholder approval of additional
authorized shares. Such a delay and attendant expense could have consequences
which may not be in the best interests of Technitrol and its shareholders.
 
  The Technitrol Common Stock is presently approved for trading on the ASE.
Pursuant to the listing standards, policies and requirements of the ASE,
Technitrol is required to obtain shareholder approval prior to the issuance of
the shares of Technitrol Common Stock when:
 
    (a) the issuance will result in a change of control of Technitrol;
 
    (b) in connection with the acquisition of the stock or assets of another
  company,
 
      (i) any individual director, officer or substantial shareholder of
    Technitrol has a 5% or greater interest (or such persons collectively
    have a 10% or greater interest), directly or indirectly, in the company
    or assets to be acquired or in the consideration to be paid in the
    transaction or series of related transactions and the present or
    potential issuance of Technitrol Common Stock, or securities
    convertible into or exercisable for Technitrol Common Stock, could
    result in an increase in outstanding Technitrol Common Stock or voting
    power of 5% or more; or
 
      (ii) the Technitrol Common Stock, or securities convertible into or
    exercisable for Technitrol Common Stock to be issued, could result in
    an increase in Technitrol Common Stock of 20% or more; or
 
    (c) in connection with a transaction other than a public offering,
 
      (i) the offering involves the sale or issuance by Technitrol of
    Technitrol Common Stock (or securities convertible into or exercisable
    for Technitrol Common Stock) at a price less than the greater of book
    or market value which together with sales by officers, directors or
    substantial shareholders of Technitrol equals 20% or more of the
    outstanding Technitrol Common Stock or 20% or more of the voting power
    outstanding before the issuance; or
 
      (ii) the offering involves the sale or issuance by Technitrol of
    Technitrol Common Stock (or securities convertible into or exercisable
    for Technitrol Common Stock) equal to 20% or more of the outstanding
    Technitrol Common Stock or 20% or more of the voting power outstanding
    before the issuance for less than the greater of book or market value
    of the stock.
 
  This proposal is not being recommended in response to any specific effort of
which Technitrol is aware to obtain control of Technitrol, nor is it part of
any plan by Technitrol to adopt a proposal or a series of proposals relating
to a possible takeover of Technitrol. The Technitrol Board has no present
intention of soliciting a shareholder vote on any other such proposal. If this
proposal is approved, however, the additional authorized shares of Technitrol
Common Stock could be issued to dilute the stock ownership of persons who in
the future seek control of Technitrol. Except as noted above, however, the
Technitrol Board has no present plans to issue any of the additional shares
and would comply with the ASE rules prior to any such issuance.
 
  In addition, while the Technitrol Board presently has no intention of doing
so, the power of the Technitrol Board to issue Technitrol Common Stock could
enable the Technitrol Board (without shareholder approval) to
 
                                      70
<PAGE>
 
put into effect a share rights purchase plan (commonly known as a "poison
pill") to deter coercive takeover tactics and preserve shareholders' equity
value.
 
  Lastly, the Charter and Technitrol's Bylaws also contain provisions that
could have the effect of delaying, deterring or preventing changes of control
or management of Technitrol. More specifically, Technitrol's Charter and
Bylaws provide (i) for a Board of Directors only one-third of which is elected
each year, (ii) a limitation on the number of directors on the Technitrol
Board to nine (9), (iii) that twenty percent (20%) of the shareholders are
required to call a special meeting of the shareholders, (iv) for approval of
seventy-five percent (75%) of voting shareholders to amend Bylaws concerning
the number, terms and removal of the Technitrol Board, and (v) for approval of
seventy-five percent (75%) of voting shareholders to approve a merger, a sale
of substantially all of the corporation's assets, or an issuance or delivery
of securities in exchange for assets of another corporation.
 
  Although the Technitrol Board presently has no intention of doing so, the
availability of authorized but unissued shares could permit Technitrol Common
Stock (within the limits imposed by applicable law and the rules of the ASE
and/or any other exchanges on which the Technitrol Common Stock is listed) to
be issued to a holder who might thereby obtain sufficient voting power to
ensure that any proposal to remove directors or to approve a merger or other
business combinations or to amend or repeal any of the foregoing provisions
would not receive the 75% shareholder vote required therefor. Thus, the power
of the Technitrol Board to issue stock could enable the Technitrol Board to
make it more difficult to replace incumbent directors and to effect a change
in control of Technitrol through a merger or other business combination.

                         CERTAIN RELATED TRANSACTIONS
 
TECHNITROL PURCHASE OF OUTSTANDING PULSE WARRANT
 
  On May 22, 1995, Technitrol acquired a warrant from an unrelated third party
to purchase 655,489 shares of Pulse Class B Stock at a warrant exercise price
of $1.00 per share (the "Warrant"). The purchase price for the Warrant was
$4,768,682.48. Technitrol acquired the Warrant in anticipation of entering
into the Merger Agreement. Shares of Pulse Class B Stock are convertible, at
the option of the holder, into shares of Pulse Common Stock. The Warrant
represents beneficial ownership of approximately 10.46% of the issued and
outstanding Pulse Stock (including shares that would be issued upon the full
exercise of the Warrant, but excluding shares held by Pulse as treasury
shares).
 
PULSE ARRANGEMENTS WITH CERTAIN OF ITS OFFICERS
 
  Interests of Certain Persons in the Merger. Certain members of Pulse's
management and the Pulse Board have interests in the Merger in addition to
their interests, if any, as stockholders of Pulse generally. The Pulse Board
was aware of these factors and considered them, among other matters, in
approving the Merger and the Merger Agreement.
 
  Executive and Key Employee Severance Arrangements. On May 22, 1995, the
Pulse Board adopted severance arrangements for certain of its key employees.
Generally, these severance arrangements (i) cover Messrs. David Flowers,
Michael Brosnan, Russell Holman, John Houston, Leonard Luner and Patrick
McCready, (ii) supersede any other Pulse severance benefits which the
identified individuals are eligible to receive and (iii) provide for
continuation of base salary and group health insurance benefits for a
specified period following an involuntary termination of employment within 12
months after the Effective Time, with such specified period subject to
extension for any months remaining in the six-month period immediately
following the Effective Time if an involuntary termination occurs within such
six-month period. In each instance, "involuntary termination" includes a
unilateral reduction in compensation or a material adverse change in working
conditions.
 
  Under the severance arrangements for Mr. Flowers, if his employment with the
Surviving Corporation is involuntarily terminated or if employment
arrangements satisfactory to Mr. Flowers are not reached within 12 months
following the Effective Time, his salary and benefits will be continued for a
period of 15 months following the date of involuntary termination (subject to
possible extension as referenced above). In consideration for such severance
benefits, Mr. Flowers will (i) assist Technitrol management in providing a
smooth transition with respect to consolidation of Pulse operations with the
Technitrol Electronic Products Segment, (ii) undertake reasonable special
projects when so requested, (iii) be provided with certain office equipment
and furniture to maintain an office within his home, (iv) be reimbursed for
expenses associated with establishing and maintaining a private telephone and
fax line, and (v) be provided with out placement assistance through an
independent agency, subject to limitations of a maximum expenditure of $30,000
during a period of 24 months following the Effective Time. Mr. Flowers will
report directly to the President of Technitrol.
 
  The severance arrangements for Messrs. Brosnan, Holman, Houston, Luner and
McCready will take effect in the event that their employment is involuntarily
terminated within 12 months following the Effective Time. Each person's
severance arrangement will consist of salary and benefits for six months
following the date of involuntary termination (subject to possible extension
as referenced above).
 
  In addition to the foregoing severance arrangements, the Pulse Board on May
22, 1995 determined to pay retention bonuses to Messrs. Holman and McCready in
the amounts of $30,000 and $10,000, respectively, conditioned upon such
individuals' remaining Pulse employees through the Effective Time. The bonus
payments were authorized in order to help assure the continued assistance of
Messrs. Holman and McCready in the legal and financial aspects of the Merger.
 
  Stock Option Agreements. Certain of Pulse's stock option agreements, as well
as the employee benefit plans to which such agreements relate, provide that an
event such as the Merger will cause the underlying options
 
                                      72
<PAGE>
 
to terminate upon the effectiveness of such event (in the case of the Merger,
at the Effective Time); however, prior to any such termination the
exercisability of the options is accelerated (i.e., the options become
exercisable in full, whether or not then otherwise exercisable or "vested").
Technitrol and Pulse have agreed, subject to approval and adoption of the
Merger Agreement by the stockholders of Pulse, to amend all such Pulse stock
option agreements and the employee benefit plans to which these agreements
relate to prevent the Merger from terminating any options which would
otherwise become Assumed Options. These amendments will affect certain
officers and Directors of Pulse, although the amendments apply to all holders
of such options. Technitrol has further undertaken that the unvested portion
of options held by Pulse Directors will not be forfeited because such
individuals do not continue as directors of the Surviving Corporation.
 
  Indemnification. The Merger Agreement provides that, from and after the
Effective Time the Surviving Corporation will indemnify, defend and hold
harmless the present and former officers and Directors of Pulse (collectively,
the "Indemnified Parties") against all losses, expenses, claims, damages,
liabilities or amounts that are paid in settlement of (with the approval of
Technitrol and the Surviving Corporation, which approval shall not be
unreasonably withheld) or otherwise in connection with any claim, action,
suit, proceeding or investigation (a "Claim"), based in whole or in part on
the fact that such person is or was an officer or Director of Pulse and
arising out of actions or omissions occurring at or prior to the Effective
Time (including, without limitation, the transactions contemplated by this
Agreement), in each case to the full extent permitted under the DGCL. The
Surviving Corporation will also pay expenses in advance of the final
disposition of any such action or proceeding to each Indemnified Party to the
fullest extent permitted under the DGCL, upon receipt from the Indemnified
Party to whom expenses are advanced of an undertaking to repay such advances.
Technitrol has agreed to guarantee the obligations of the Surviving
Corporation in this regard.
 
  In addition to the foregoing indemnification, (i) for a period of two years
after the Effective Time, Technitrol will cause to be maintained in effect the
current policies of Directors' and officers' liability insurance maintained by
Pulse (provided that Technitrol may substitute therefor policies of at least
the same coverage and amounts) and (ii) the charter documents of the Surviving
Corporation shall contain the provisions with respect to indemnification which
are set forth in the charter documents of Pulse, which provisions shall not be
modified for a period of six years after the Effective Time in any manner
which would adversely affect the rights thereunder of individuals who at any
time prior to the Effective Time were Directors or officers of Pulse in
respect of actions or omissions occurring at or prior to the Effective Time
(including, without limitation, the transactions contemplated by this
Agreement), unless such modification is required by law.

    64,834 shares and 307,165 shares, respectively, of Pulse Common Stock
    subject to options or warrants exercisable immediately or within sixty
    days, and the percentages of outstanding stock beneficially owned by each
    of such persons and such group were computed based on the number of shares
    (excluding shares held by Pulse as treasury shares) which would have been
    outstanding if the options or warrants of each (but not of the others) had
    been exercised. The options have exercise prices ranging from $1.00 per
    share to $9.00 per share. Of the shares subject to options beneficially
    owned by Mr. Bailey, 9,250 shares are held as a nominee of Oppenheimer.
(3) Consists of 655,489 shares of Pulse Class B Stock issuable upon the
    exercise of a warrant that is immediately exercisable. See "CERTAIN
    RELATED TRANSACTIONS--Technitrol Purchase of Outstanding Pulse Warrant."
    Under the Pulse Certificate of Incorporation, each share of Pulse Class B
    Stock is immediately convertible into one share of Pulse Common Stock. It
    is anticipated that such warrant will be canceled at the Effective Time.

                    DESCRIPTION OF TECHNITROL CAPITAL STOCK
 
  The authorized capital stock of Technitrol consists of 10,000,000 shares of
Technitrol Common Stock. The Charter Amendment, if adopted, would increase the
authorized capital stock of Technitrol to 30,000,000 shares of Technitrol
Common Stock. See "PROPOSAL TO INCREASE AUTHORIZED SHARES OF TECHNITROL COMMON
STOCK."
 
  As of the Technitrol Record Date, there were 6,047,742 shares of Technitrol
Common Stock outstanding held of record by approximately 704 shareholders.
Holders of Technitrol Common Stock are entitled to one vote per share on all
matters to be voted upon by the shareholders. In the event of a liquidation,
dissolution or winding up of Technitrol, the holders of Technitrol Common
Stock are entitled to share ratably in all assets remaining after payment of
liabilities. Technitrol Common Stock has no preemptive or other subscription
rights. All outstanding shares of Technitrol Common Stock are fully paid and
non-assessable except for shares issued pursuant to Technitrol's Restricted
Stock Plan which are subject to the terms of such Restricted Stock Plan, and
the shares of Technitrol Common Stock to be outstanding upon completion of the
Merger will be fully paid and non-assessable (except for shares issued
pursuant to Technitrol's Restricted Stock Plan).
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar for Technitrol Common Stock is Registrar
and Transfer Company, 10 Commerce Drive, Cranford, New Jersey, 07016, and its
telephone number is (908) 272-8511.
 
                 COMPARISON OF RIGHTS OF HOLDERS OF TECHNITROL
                COMMON STOCK AND HOLDERS OF PULSE COMMON STOCK
 
  Upon consummation of the Merger, the stockholders of Pulse, a Delaware
corporation, will become shareholders of Technitrol, a Pennsylvania
corporation. Although the Delaware General Corporation Law, ("DGCL" or
"Delaware Law") and the Business Corporation Law of Pennsylvania ("PBCL" or
"Pennsylvania Law") are similar in many respects, there are a number of
differences between the two statutes which should be carefully considered by
Pulse stockholders in evaluating the Merger. The following summary, which sets
forth certain material differences between the two statutes, does not purport
to be a complete statement of all differences between the DGCL and PBCL, nor
does it purport to be a complete statement of the provisions of the two
statutes which it compares.
 
FIDUCIARY DUTIES OF DIRECTORS
 
  Both Delaware Law and Pennsylvania Law provide that the board of directors
has the ultimate responsibility for managing the business affairs of a
corporation. In discharging this function, directors owe fiduciary duties of
care and loyalty to the corporation and to its securityholders.
 
  Delaware courts have held that the duty of care requires the directors to
exercise an informed business judgment. An informed business judgment means
that the directors have informed themselves of all material
 
                                      77
<PAGE>
 
information reasonably available to them. Delaware courts have, under certain
circumstances, also imposed a heightened standard of conduct upon directors in
matters involving a contest for control of the corporation.
 
  Similar to Delaware Law, Pennsylvania Law requires that directors perform
their duties in good faith. The PBCL, however, contains a provision
specifically permitting (though not requiring) directors, in discharging their
duties, to consider the effects of any action taken by them upon any or all
affected groups (including, e.g., shareholders, members, employees, suppliers,
customers, creditors and the community in which the corporation operates) as
well as all other pertinent factors. Furthermore, unlike Delaware Law, the
PBCL makes clear that a director has no greater burden to justify any act
relating to an actual or potential acquisition of the corporation than he or
she has regarding any other act as a director.
 
LIMITATION OF DIRECTOR LIABILITY
 
  Both Delaware Law and Pennsylvania Law permit a corporation's certificate
(articles) of incorporation or bylaws to limit a director's exposure to
monetary liability for breach of fiduciary duty.
 
  Pursuant to Delaware Law, a director cannot be relieved of liability for (i)
breach of his/her duty of loyalty to the company, (ii) acts or omissions not
in good faith or constituting intentional misconduct or knowing violation of
the law, (iii) declaration of an improper dividend, stock purchase or
redemption of shares, or (iv) any transaction from which the director derived
an improper personal benefit.
 
  Similarly, pursuant to Pennsylvania Law, a director cannot be relieved of
liability for (i) breach of his/her statutory duties of care and good faith to
the company, (ii) breach or omission constituting self-dealing, willful
misconduct or recklessness, (iii) violation of criminal statutes, or (iv) non-
payment of federal, state or local taxes.
 
INDEMNIFICATION
 
  Both Delaware Law and Pennsylvania Law permit a corporation to indemnify any
person involved in a third party action by reason of his/her being an officer
or director of the corporation, against expenses, judgments, fines and
settlement amounts paid in such third party action (and against expenses
incurred in any derivative action), if such person acted in good faith and
reasonably believed that his/her actions were in, or not opposed to, the best
interests of the corporation. With respect to any criminal proceeding, both
Delaware Law and Pennsylvania Law permit indemnification when the director or
officer had no reasonable cause to believe that his/her conduct was unlawful.
Furthermore, both states' laws provide that a corporation may advance expenses
incurred in defending any action upon receipt of an undertaking by the person
to repay the amount advanced if it is ultimately determined that he/she is not
entitled to indemnification.
 
  In general, no indemnification for expenses in derivative actions is
permitted under either the DGCL or the PBCL where the person has been adjudged
liable to the corporation, unless a court finds him entitled to such
indemnification. If, however, the person has been successful in defending a
third party or derivative action, indemnification for expenses incurred is
mandatory under both states' laws.
 
  In both states, the statutory provisions for indemnification are
nonexclusive with respect to any other rights, such as contractual rights
under a bylaw, agreement or vote of stockholders or disinterested directors to
which a person seeking indemnification may be entitled. Unlike Delaware Law,
however, Pennsylvania Law expressly permits such contractual or other rights
to provide for indemnification in connection with a third party action,
including a derivative action, unless a court determines that the acts or
omissions giving rise to the claim for indemnification constituted willful
misconduct or recklessness.
 
SHAREHOLDER PROTECTIVE PROVISIONS
 
  Both Delaware Law and Pennsylvania Law contain provisions which provide
protection to shareholders, and the corporation in which they own shares,
against abusive acquisition and takeover techniques.
 
                                      78
<PAGE>
 
  Under the DGCL, a corporation is prohibited from engaging in any business
combination with an interested stockholder (beneficial owner of 15% or more of
the corporation's voting stocks) for a period of three years from the date the
stockholder became interested, unless (i) prior to such date, the board of
directors approved either the business combination or the transaction which
resulted in the stockholder becoming an interested stockholder, (ii) the
interested stockholder acquired 85% of the voting stocks at the time the
transaction commenced, or (iii) on or subsequent to such date the business
combination is approved by the board and 66 2/3% of the noninterested
stockholders. This provision of the DGCL does not apply to a corporation if
the certificate of incorporation or bylaws contain a provision expressly
electing not to be governed by this provision or the corporation does not have
voting stock either listed on a national securities exchange, authorized for
quotation on an inter-dealer quotation system of a registered national
securities association or held of record by more than 2,000 stockholders.
 
  Unlike Delaware Law, under the PBCL, a corporation is permanently prohibited
from engaging in any business combination with an interested shareholder
(defined in Pennsylvania as a beneficial owner of 20% or more of the
corporation's voting shares) unless (i) the shareholder became interested
after the date the board of directors approved the business combination, (ii)
within three months after the date the shareholder became interested, and
his/her beneficial ownership amounts to 80% of the corporation's voting
shares, the business combination is approved by the noninterested shareholders
and it meets certain other conditions concerning amount of consideration,
(iii) at any time after the date the shareholder became interested, the
business combination is approved by unanimous vote of the shareholders, (iv)
within five years after the date the shareholder became interested, the
business combination is approved by a majority of the noninterested
shareholders, or (v) within five years after the date the shareholder became
interested, the business combination is approved by a majority of all
shareholders and meets certain conditions set forth in the PBCL which concern
the amount of consideration. Unless the articles of incorporation provide
otherwise, this provision of the PBCL does not apply to a corporation if the
corporation does not have voting shares either registered or traded on a
national securities exchange or registered with the SEC.
 
AMENDMENTS TO CERTIFICATE (ARTICLES) OF INCORPORATION
 
  Under Delaware Law, amending the certificate of incorporation generally
requires the approval of the holders of a majority of the shares of stock
entitled to vote. Pennsylvania Law only requires the affirmative vote of a
majority of the votes cast by the holders of shares entitled to vote on a
proposed amendment, unless a specific provision of the PBCL or the articles of
incorporation requires a greater percentage.
 
MERGERS AND MAJOR TRANSACTIONS
 
  Under Delaware Law, fundamental corporate transactions (such as mergers,
sales of all or substantially all of the corporation's assets, dissolutions,
etc.) require the approval of the holders of a majority of the outstanding
stock entitled to vote. Pennsylvania Law reduces the approval threshold to a
majority of the votes cast. Delaware Law and Pennsylvania Law each permit a
corporation to increase the minimum percentage vote required above the
statutory minimums described above.
 
DIVIDENDS
 
  Delaware Law permits dividends to be paid out of (i) surplus (the excess of
net assets of the corporation over capital) or (ii) net profits for the
current and/or the then preceding fiscal year, unless the net assets are less
than the capital of any outstanding preferred stock. Pennsylvania Law permits
the payment of dividends, called distributions, unless after payment (i) the
corporation would be unable to pay its debts as they become due in the usual
course of its business, or (ii) the corporation's total assets would be less
than its total liabilities.
 
SHARE REPURCHASE
 
  Under Delaware Law, a corporation may not purchase or redeem its own stock
by reducing the capital represented by such shares unless the assets of the
corporation remaining after such reduction shall be sufficient to pay any
debts of the corporation for which payment has not been otherwise provided.
There is no similar restriction in Pennsylvania Law.
 
                                      79
<PAGE>
 
VOTING RIGHTS
 
  Under Delaware Law, cumulative voting in the election of directors is only
permitted if expressly authorized in a corporation's certificate of
incorporation. Under Pennsylvania Law, however, cumulative voting is permitted
unless, (i) disallowed by the articles; or (ii) the shareholder was not
permitted to cumulate his/her votes at the date of incorporation, unless
authorized by the articles.
 
APPRAISAL OR DISSENTERS RIGHTS
 
  The rights of shareholders to demand payment in cash by a corporation of the
fair value of their shares under certain circumstances are called appraisal
rights under the DGCL and dissenters rights under the PBCL. Delaware Law does
not afford appraisal rights to holders of shares which are either listed on a
national securities exchange, quoted on the Nasdaq Stock Market or held of
record by more than 2,000 stockholders, unless the plan of merger or
consolidation converts such shares into anything other than shares of the
surviving corporation or shares of stock of another corporation which, at the
effective date of the merger or consolidation, will either be listed on a
national securities exchange, quoted on Nasdaq Stock Market or held of record
by more than 2,000 stockholders.
 
  Pennsylvania does not afford dissenters rights to shareholders of a
corporation which is a party to any plan of merger (i) with respect to shares
of a class or series which is listed on a national securities exchange or is
held on the record date by more than 2,000 shareholders or (ii) when such
shareholder holds the shares of the acquiring corporation.
 
AMENDMENTS TO BYLAWS
 
  Under Delaware Law, the certificate of incorporation may confer on the board
of directors the power to amend the bylaws. Additionally, the DGCL provides
that a corporation's bylaws may be amended by the stockholders entitled to
vote, which power shall not be divested or limited where the board also has
such power. Under Pennsylvania Law, the shareholders retain the right to amend
the bylaws and the board of directors may be given the power to amend bylaws
unless the subject of such amendment is solely the province of the
shareholders.
 
ACTION BY WRITTEN CONSENT
 
  Delaware Law permits a majority or higher required percentage of
stockholders entitled to vote to consent in writing to any action that could
be taken by stockholders at a meeting, unless the certificate of incorporation
prohibits such written consent. Pennsylvania Law permits, if the bylaws
provide, any corporate action to be taken by nonunanimous shareholder consent
without a meeting, where shareholders having the minimum number of votes that
would be necessary to take such action at a meeting sign written consents.
 
SPECIAL MEETING OF SHAREHOLDERS
 
  Under Delaware Law, a special meeting of the stockholders may be called by
the board of directors or such other person as may be authorized by the
certificate of incorporation or bylaws. Pennsylvania Law permits a special
meeting of shareholders to be called by the board of directors, officers, an
interested shareholder for the purpose of approving a business combination, or
a group of shareholders as the articles may provide.
 
ANNUAL MEETING OF SHAREHOLDERS
 
  Under Delaware Law, if the annual meeting for the election of directors is
not held on the designated date, the directors are required to cause such a
meeting to be held as soon thereafter as convenient. If they fail to do so for
a period of 30 days after the designated date, or if no date has been
designated for a period of 13 months after the organization of the corporation
or after its last annual meeting, the Court of Chancery may summarily order a
meeting to be held upon the application of any stockholder or director.
 
                                      80
<PAGE>
 
  Under Pennsylvania Law, if the annual meeting for election of directors is
not held on the designated date the directors are required to cause such a
meeting to be held as soon thereafter as may be convenient. If they fail to do
so for a period of six months after the designated date, any shareholder may
call the meeting at any time thereafter.
 
CASE LAW AND COURT SYSTEMS
 
  There is a substantial body of case law in Delaware interpreting the
corporation laws of that state. A comparable body of judicial interpretation
does not yet exist in Pennsylvania. Delaware also has established a system of
Chancery Courts to adjudicate matters arising under the DGCL. Pennsylvania
does not have an equivalent court system. As a result of these factors, there
may be less certainty as to the outcome of matters governed by the PBCL, and
therefore it may be more difficult to obtain legal guidance as to such matters
than would be the case under Delaware Law.
 
INSPECTION OF BOOKS AND RECORDS
 
  Both Delaware and Pennsylvania law allow a securityholder, upon written
demand, to examine the books and records of a corporation (including records
of proceedings of shareholders and directors) for any reason reasonably
related to the interest of a person as a shareholder.
 
                          PULSE STOCKHOLDER PROPOSALS
 
  If the Merger is not consummated, proposals of stockholders of Pulse
intended to be presented at the 1996 annual meeting of Pulse must be received
no later than June 9, 1996, by the Acting Corporate Secretary of Pulse at its
principal executive office at 12220 World Trade Drive, San Diego, California
92128, in order to be eligible for consideration for inclusion in Pulse's
proxy statement for such meeting.
 
                       TECHNITROL SHAREHOLDER PROPOSALS
 
  Proposals of shareholders of Technitrol intended to be presented at the 1996
annual meeting of Technitrol must be received no later than December 22, 1995,
by the Secretary of Technitrol at its principal executive office at 1210
Northbrook Drive, Suite 385, Trevose, Pennsylvania 19053, in order to be
eligible for consideration for inclusion in Technitrol's proxy statement for
such meeting.

                  Notes to Consolidated Financial Statements

(1)  Accounting Policies
     -------------------

   For a complete description of the accounting policies of Technitrol, Inc. and
its consolidated subsidiaries ("the Company"), refer to Note 1 to the financial
statements included in the Company's Form 10-K filed for the year ended December
31, 1994.

Reclassifications

   Certain amounts in the 1994 financial statements have been reclassified to
conform with the current year's presentation.

(2)  Acquisitions
     ------------

   On January 17, 1994, the Company, through its wholly-owned subsidiary,
Technitrol International, Inc., a Delaware corporation, acquired from FEE
Technology, S.A. all of the issued and outstanding capital stock of FEE Fil-Mag
Taiwan Corporation ("FFT"), FEE Fil-Mag Singapore Pte. Corporation ("FFS") and
Fil-Mag, Inc. ("FMI"). FFT, FFS and FMI are referred to below as the "Fil-Mag
Group". The Fil-Mag Group is a supplier of magnetic components to domestic and
international manufacturers of PCs, network interface cards, network controllers
and other devices that are connected to data communications networks such as
Token Ring and Ethernet. The Fil-Mag Group conducts manufacturing operations in
its plants in Taiwan and the Philippines, engineering activities at its San
Diego, California location and sales operations through offices in France,
Singapore and San Diego. The Company intends to continue the businesses of the
Fil-Mag Group at their current locations.

     The purchase price was $9,082,000 (net of expenses). In addition, the
Company caused FMI to repay to FEE Technology, S.A. approximately $1 million of
indebtedness. FFT was indebted to local banks in the amount of approximately
$3.3 million, all of which has been retired since the acquisition. The purchase
price and the $1 million debt repayment were financed by borrowing $10 million
under a temporary acquisition line of credit and cash on-hand of approximately
$400,000.

     The purchase price was arrived at pursuant to arms-length negotiations
taking into account all pertinent factors including, but not limited to, the
nature, monetary and strategic value of the assets being acquired, the
businesses and business prospects of each member of the Fil-Mag Group and the
synergies of the businesses of the Fil-Mag Group with the operations of the
Components Division of the Company. The assets acquired had a fair value of
approximately $18.0 million, including current assets of $9.0 million and
approximately $2.5 million of goodwill associated with the acquisition.
Liabilities assumed totaled $8.6 million.

     Subsequent to the acquisition, eight key employees of the Fil-Mag Group
entered into a covenant against competition with the Company in exchange for
which the Fil-Mag Group paid them, in the aggregate, $1 million during the
twelve months subsequent to the acquisition. The $1 million was financed by cash
on-hand and is being amortized on a straight-line basis over the life of the
covenant.

     The activity of the Fil-Mag Group for the period from January 1 to January
17, 1994, was not material to the consolidated results of the Company.

(3)  Shareholders' Equity
     --------------------

       On August 3, 1994, the Company's Board of Directors approved a three-for-
one split of the Company's common stock in the form of a 200% common stock
dividend for shareholders of record as of August 18, 1994. A total of 5,962,640
shares were issued in connection with the split. The stated par value of each
share was not changed from $.125. A total of $745,000 was reclassified from the
Company's retained earnings account to the Company's common stock account. All
share and per share amounts for 1994 have been restated to retroactively reflect
the stock split.

(4)  Supplemental Disclosure of Non-cash Transactions
     ------------------------------------------------

   During the six months ending June 30, 1995 and 1994, the Company issued to
employees stock pursuant to the Company's Restricted Stock Plan having a fair
value of $406,000 and $469,000, respectively.

(5)  Merger Agreement with Pulse Engineering, Inc.
     -------------------------------------------- 

       On May 23, 1995, the Company and Pulse Engineering, Inc. ("Pulse")
jointly announced that their respective Boards of Directors had approved a
definitive merger agreement. Under the agreement, the Company will acquire all
the issued and outstanding Pulse shares for approximately $24.0 million in cash
and approximately 1,650,000 shares of the Company's stock and Pulse will become
a wholly-owned subsidiary of the Company. Pulse stockholders can elect to
receive all cash or all common stock of the Company, subject to the limitation
that no more than 55% and no less than 50% of the Pulse shares will be converted
to the Company's common stock. A stockholder receiving an equal allocation of
cash and the Company's common stock will receive $4.25 in cash and .2906 shares
of the Company's common stock for each Pulse share. At closing, the exchange
ratio will be adjusted upward if the average closing price for the Company's
stock is below $13-3/4 (equal to $8.00 per Pulse share) and will be adjusted
downward if the average closing price is above $16-3/8 (equal to $9.52 per Pulse
share), both calculated on the closing price of the Company's common stock
during a ten trading day period preceding closing. The purchase price, if a
Pulse stockholder receives 50% cash and 50% Technitrol common stock, will be no
less than $8.25 nor more than $9.01 per Pulse share.

       The Company's and Pulse's Boards of Directors will recommend to their
respective shareholders that they approve the merger at special meetings of the
shareholders to be called in September, 1995. The merger is subject to various
conditions which are normal and customary in transactions of this type including
receipt of required regulatory approvals.

       The Company also acquired a warrant from an unrelated third party to
purchase 655,489 shares of Pulse common stock at a warrant exercise price of
$1.00 per share. The purchase price for the warrant was approximately
$4,769,000. Based upon Pulse's most recent public filings, the warrant
represents beneficial ownership of approximately 9.1% of the issued and
outstanding Pulse common stock.

       Pulse, headquartered in San Diego, California, with operations in Hong
Kong, the People's Republic of China and Ireland, designs, manufactures and
markets electronic components and modules primarily for manufacturers of local
area networks and telecommunications systems.

                         INDEPENDENT AUDITORS' REPORT



The Board of Directors and Shareholders
Technitrol, Inc.



We have audited the accompanying consolidated balance sheets of Technitrol, Inc.
and subsidiaries as of December 31, 1994 and 1993 and the related consolidated
statements of earnings and retained earnings and cash flows for each of the
years in the three-year period ended December 31, 1994. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.


We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.


In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Technitrol, Inc. and
subsidiaries at December 31, 1994 and 1993, and the results of their operations
and their cash flows for each of the years in the three-year period ended
December 31, 1994, in conformity with generally accepted accounting principles.


As discussed in note 6 to the consolidated financial statements, the Company
changed its method of accounting for income taxes in 1993 to adopt the
provisions of the Financial Accounting Standards Board's Statement of Financial
Accounting Standards No. 109, Accounting for Income Taxes.

                  Notes to Consolidated Financial Statements

(1)     Summary of Significant Accounting Policies
        ------- -- ----------- ---------- --------

Principles of Consolidation
---------- -- -------------
          The consolidated financial statements include the accounts of
Technitrol, Inc. (the "Company") and all of its subsidiaries. All material
intercompany accounts and transactions are eliminated in consolidation.

Cash and Cash Equivalents
---- --- ---- -----------
          Cash and cash equivalents include funds invested in a variety of
liquid short-term investments with a maturity of three months or less.

Inventories
-----------
          Inventories are stated at the lower of cost or market. Cost is
determined by the first-in, first-out (FIFO) method. In addition to the
inventories included in the accompanying balance sheets, the Company has custody
of inventories on consignment from suppliers ($14,063,000 at December 31, 1994
and $11,092,000 at December 31, 1993).

Property, Plant and Equipment
--------  ----- --- ---------
          Property, plant and equipment are stated at cost. Depreciation is
based upon the estimated useful life of the assets and has been provided for on
both the accelerated and the straight line methods. Expenditures for maintenance
and repairs are charged to operations as incurred, and major renewals and
betterments are capitalized. Upon sale or retirement, the cost of the asset and
related accumulated depreciation are removed from the balance sheet, and any
resulting gains or losses are included in earnings.

Excess of Cost over Net Assets
------ -- ---- ---- --- ------
          Excess of cost over net assets acquired (which the Company believes
has continuing value) is being amortized on a straight-line basis over 15 years.
The recoverability of the carrying value of intangible assets is evaluated on a
recurring basis.

Earnings per Share
-------- --- -----
          Earnings per share are calculated based on the weighted average number
of common shares outstanding. Earnings per share for prior years have been
restated to reflect a 200% stock dividend recorded on September 18, 1994.

Foreign Currency Translation
------- -------- -----------
          The financial statements of the Company's foreign subsidiaries have
been translated into U.S. dollars in accordance with Financial Accounting
Standards Board Statement No. 52. All balance sheet accounts have been
translated using the year-end exchange rate and all income statement accounts
have been translated using the average exchange rate for the year. The gains and
losses resulting from the change in exchange rates from the date of acquisition
to the current balance sheet date have been reported separately as a component
of shareholders' equity. Transaction gains and losses are recorded in the
statement of earnings for the year in which they occur.

(2)     Acquisitions
        ------------

  On January 17, 1994, the Company, through its wholly-owned subsidiary,
Technitrol International, Inc., a Delaware corporation, acquired from FEE
Technology, S.A. all of the issued and outstanding capital stock of FEE Fil-Mag
Taiwan Corporation ("FFT"), FEE Fil-Mag Singapore Pte. Corporation ("FFS") and
Fil-Mag, Inc. ("FMI"). FFT, FFS and FMI are referred to below as the "Fil-Mag
Group". The Fil-Mag Group is a supplier of magnetic components to domestic and
international manufacturers of PCs, network interface cards, network controllers
and other devices that are connected to data communications networks such as
Token Ring and Ethernet. The Fil-Mag Group conducts manufacturing operations in
its plants in Taiwan and the Philippines; engineering activities at its San
Diego, California location; and sales operations through offices in France,
Singapore and San Diego. The Company intends to continue the businesses of the
Fil-Mag Group at their current locations.

       The purchase price was $9,082,000 (net of expenses). In addition, the
Company caused FMI to repay to FEE Technology, S.A. approximately $1 million of
indebtedness. FFT was indebted to local banks in the amount of approximately
$3.3 million, of which approximately $2.5 million was retired during 1994. The
purchase price and the $1 million debt repayment were financed by borrowing $10
million under a temporary acquisition line of credit and cash on-hand of
approximately $400,000.

       The purchase price was arrived at pursuant to arms-length negotiations,
taking into account all pertinent factors including, but not limited to, the
nature, monetary and strategic value of the assets being acquired, the
businesses and business prospects of each member of the Fil-Mag Group and the
synergies of the businesses of the Fil-Mag Group with the operations of the
Components Division of the Company. The assets acquired had a fair value of
approximately $18.0 million, including current assets of $9.0 million and
approximately $2.5 million of goodwill associated with the acquisition.
Liabilities assumed totaled $8.6 million.

       Subsequent to the acquisition, eight key employees of the Fil-Mag Group
entered into a covenant against competition with the Company in exchange for
which the Fil-Mag Group paid them, in the aggregate, $1 million during the
twelve months subsequent to the acquisition. The $1 million was financed by cash
on-hand.

       The acquisition has been accounted for by the purchase method of
accounting. Had the business been acquired on January 1, 1993, unaudited
consolidated pro forma results would have been:

The activity of the Fil-Mag Group for the period from January 1 to January 17,
1994, was not material to the consolidated results of the Company.

        This unaudited pro forma information is provided for comparative
purposes only. It does not purport to be indicative of the results that actually
would have occurred if the acquisition had been consummated on the date
indicated or which may be obtained in the future.

        On February 12, 1992, the Company purchased all of the issued and
outstanding shares of the capital stock of Doduco Corporation. Upon acquisition,
the name of the acquired business was changed to AMI-DDC, Inc. ("AMI-DDC"). AMI-
DDC is engaged in the business of manufacturing electrical contacts. The cost of
the acquisition amounted to $728,000, consisting of $111,000 of acquisition
costs and $617,000 cash paid for all outstanding shares of common stock. Funded
indebtedness of AMI-DDC of $3.6 million was repaid during March of 1992, and an
additional $2.5 million was repaid in April of 1992. The purchase price and debt
repayments were financed by borrowing $5.9 million under a revolving credit loan
(with a maximum draw of $6 million) and cash on hand of approximately $1.1
million.

        The acquisition was accounted for by the purchase method of accounting.
Had the business been acquired on January 1, 1992, pro forma results of
operations would have been:

        In January 1994, the Company borrowed $10 million under a temporary
acquisition line of credit as described in Note 2. In March 1994, this amount
was refinanced along with the $5 million outstanding at December 31, 1993, into
a single variable-rate revolving bank loan facility with a maximum draw of $20
million, maturing in March 1997. On February 9, 1995, $2 million of the $15
million outstanding at December 31, 1994 was repaid and the committed facility
was reduced from $20 million to $13 million.


        The Bank Loan facilities are unsecured and contain certain covenants
requiring maintenance of minimum net worth and other customary and normal
provisions. The Company is in compliance with all such covenants.

(5)     Research and Development Expense
        -------- --- ----------- -------


        Research and development expense is included in cost of sales and has
not exceeded 3.3% of cost of sales in 1994, 1993 and 1992.


(6)     Income Taxes
        ------ -----


        During 1992, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("FAS
109"). FAS 109 requires a change from the deferred method of accounting for
income taxes of Accounting Principles Board Opinion 11 to the asset and
liability method of accounting for income taxes. Under the asset and liability
method of FAS 109, deferred tax assets and liabilities are recognized for the
future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases. The change in these deferred tax assets or liabilities,
including the effect of a change in tax rates, if any, from the beginning to the
end of the period generally is recognized as deferred tax expense or benefit.


        Effective January 1, 1993, the Company adopted FAS 109 and has reported
the cumulative effect of that change in the method of accounting for income
taxes in the consolidated statement of earnings for the year ended December 31,
1993. Prior year financial statements have not been restated. However, amounts
recorded for certain prior business combinations have been adjusted from their
net of tax amounts to their pre-tax amounts. Related deferred taxes have been
recognized. The effect of these adjustments on earnings before taxes is not
material.

No valuation allowance for deferred tax assets was deemed necessary at December
31, 1994 or 1993. Based on the Company's history of taxable income and its
projection of future earnings, management believes that it is more likely than
not that sufficient taxable income will be generated in the foreseeable future
to realize the deferred tax assets.

        The Company provides certain post-retirement benefits (at least
temporarily) to a small number of retirees at one of its recently acquired
businesses. These amounts have been accrued and have not had a material impact
on the Company's financial statements.


        The Company maintains a defined contribution 401(k) plan covering
substantially all U.S. employees not affected by certain collective bargaining
agreements. The Company contributes a matching amount equal to $.50 for each
$1.00 of the participant's contribution not in excess of 3% of the participant's
annual wages. The contribution expense under this plan was $165,000, $177,000
and $155,000 in 1994, 1993, and 1992, respectively.

Industry Segment Information
---------------- -----------

        As a result of the acquisition of the Fil-Mag Group in January 1994
(discussed in Note 2 of Notes to Consolidated Financial Statements), the Company
has redefined the business segments during the first quarter of 1994:

        .    The Fil-Mag Group has been added to the Electronic Products
Segment. The segment continues to also include the Company's Components
Division, but excludes the Products Division, Lloyd Instruments, Ltd. ("Lloyd
Instruments") and John Chatillon & Sons, Inc. ("Chatillon"). As a result, the
Electronic Products Segment is now composed of the Company's electronic
components business.

        .    The Electrical Products Segment has become the Metallurgical
Products Segment. This segment includes the operations of Advanced Metallurgy,
Inc. ("AMI") and Chace Precision Metals, Inc. ("Chace"). AMI manufactures
electrical contacts and assemblies for a wide range of industrial customers.
Separately, Chace produces thermostatic and clad metal products for a broad
market of industrial and consumer product manufacturers.

        .    The Mechanical Products Segment no longer exists. A newly
configured segment, the End User/Finished Products Segment, includes the
Products Division, Lloyd Instruments, and Chatillon. The Products Division
manufactures document counters and dispensers, and markets its products
internationally through distributors and on an OEM basis. Lloyd Instruments
manufactures a comprehensive range of material testing systems and markets its
products throughout the world. Chatillon is composed of two primary product
families: (1) mechanical force measurement products and mechanical scales, and
(2) electronic force measurement products and electronic scales. Chatillon's
markets are numerous and international in nature. It possesses multiple channels
of marketing and distribution.

        Identifiable assets are those assets that are utilized in each segment
to provide the respective products. Corporate assets are principally cash and
cash equivalents.

        The Company's products are sold primarily to industrial customers
through the three segments described above. All business segments' revenues are
generally recognized when products are shipped. The majority of the Company's
sales are subject to credit terms prevalent in the industries it serves.
Receivables are written off when an account is considered to be doubtful of
collection. Management believes there are no significant concentrations of
credit risk.


                                                                     (continued)

        In 1994, one customer accounted for slightly more than 10% of
consolidated sales. The customer is a Fortune 150 entity principally doing
business with the Metallurgical Products Segment. The loss of that customer
could have a material adverse effect on the Company. Another customer, then a
Fortune 50 entity principally doing business with the Metallurgical Products
Segment, produced revenues slightly exceeding 10% of total sales in 1993 and
1992. Sales to the Company's ten largest customers accounted for 38% of sales in
1994, 42% in 1993 and 41% in 1992.

                  Notes to Consolidated Financial Statements

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Principles of consolidation -- The consolidated financial statements
include the accounts of the Company and its wholly owned subsidiaries. All
intercompany balances and transactions are eliminated in consolidation.

     Fiscal year -- The Company's fiscal year ends on the Sunday closest to June
30th. Fiscal years 1995 and 1993 consist of 52 weeks of operations while fiscal
year 1994 consists of 53 weeks.

     Cash equivalents -- The Company considers all highly liquid investments
with maturities of 90 days or less at the date of purchase to be cash
equivalents. Cash equivalents are stated at cost, which approximates market
value.

     Short-term investments -- Short-term investments consist primarily of
municipal and corporate bonds, Federal agency issues and auction market
preferred stock. Such investments have maturities greater than 90 days at the
date of purchase and are stated at cost, which approximates market value.
Effective July 4, 1994 the Company adopted Statement of Financial Accounting
Standard No. 115, "Accounting for Certain Investments in Debt and Equity
Securities," which requires companies to record certain debt and equity security
investments at market value. The adoption of this standard did not have a
material impact on the Company's financial position or results of operations for
the year end July 2, 1995.

     Inventories -- Inventories are stated at the lower of cost (determined on a
first-in, first-out basis) or market.

     Property, plant and equipment -- Property, plant and equipment is stated at
cost and depreciated over the estimated useful lives of the assets (3 - 30
years) using the straight-line method.

     Concentration of credit risk -- Credit is extended based on an evaluation
of the customer's financial condition and generally collateral is not required.
Credit losses have traditionally been minimal and such losses have been within
management's expectations. The Company's accounts receivable are largely
generated from computer and networking companies with a history of timely
payment.

     Revenue recognition -- Revenue is recognized upon shipment of product.

     Research and development -- Research and development expense was $2,311,000
in 1995, $4,923,000 in 1994 and $2,300,000 in 1993.

     Income taxes -- The Company accounts for income taxes under SFAS No. 109,
"Accounting for Income Taxes."

     Per share information -- Earnings per share for fiscal years 1995 and 1993
includes both weighted average and common share equivalents outstanding. Common
share equivalents result from outstanding options and warrants to purchase
common stock. Loss per share information for fiscal 1994 is based on the
weighted average number of common shares outstanding during the year. Common
share equivalents were not included in computing the fiscal 1994 loss per share
since the effect would have been antidilutive.

2. PENDING MERGER

     The Company entered into an Agreement and Plan of Merger dated as of May
23, 1995 (the "Merger Agreement") with Technitrol, Inc. ("Technitrol"), with
principal executive offices in Trevose, Pennsylvania, and Teco Sub, Inc., a
wholly owned subsidiary of Technitrol. Under the Merger Agreement, Technitrol
will acquire all of the outstanding Class A Voting Common Stock, par value .01
per share, of the Company (the "Pulse Common Stock") in a merger transaction,
and the Company will become a wholly owned subsidiary of Technitrol.
Stockholders of the Company can elect to receive all cash or all Technitrol
common stock, $.125 par value per share ("Technitrol Common Stock"), subject to
the limitation that not less than 50% and not more than 55% of the outstanding
shares of Pulse Common Stock will be converted into Technitrol Common Stock.
Each share of Pulse Common Stock (except for shares held in the Company's
treasury and shares as to which dissenters' rights are

2. PENDING MERGER (CONTINUED)

perfected) will be converted into the right to receive (i) shares of Technitrol
Common Stock determined in accordance with the exchange ratio of .5812 shares of
Technitrol Common Stock for each share of Pulse Common Stock, (ii) $8.50 or
(iii) a combination of shares of Technitrol Common Stock and cash determined in
accordance with the terms of the Merger Agreement. The exchange ratio will,
however, be adjusted downward if the average closing price of Technitrol Common
Stock during the ten trading days immediately prior to the three business days
preceding the close of the transaction exceeds $16.375 (equal to $9.52 per share
of Pulse Common Stock) or will be increased if the average closing price of
Technitrol Common Stock during such period is less than $13.75 (equal to $8.00
per share of Pulse Common Stock). Accordingly, if a stockholder of the Company
receives 50% cash and 50% Technitrol Common Stock in exchange for shares of
Pulse Common Stock, the minimum amount that would be received in the transaction
would be $8.25 per share, and the maximum amount would be $9.01 per share. The
closing price of Technitrol common stock was $16.375 on August 11, 1995.

     Completion of the merger transaction is conditioned upon, among other
things, approval of the transaction by the stockholders of each company and the
receipt of a favorable opinion from the financial advisors of each company as to
the fairness, from a financial point of view, of the consideration to be
received by Pulse stockholders. Since signing the Merger Agreement, the parties
have obtained clearance under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976 and have filed preliminary proxy material with the Securities and
Exchange Commission. The Company anticipates that definitive proxy material
reflecting the Board's recommendation that stockholders approve the proposed
transaction will be mailed to stockholders in mid-to-late August. The Company
expects to hold its special meeting of stockholders called to consider and vote
on the merger in late September, on the same day as the Technitrol special
meeting of shareholders. Assuming the transaction is approved by the
stockholders of both companies, the parties expect the merger to be completed
shortly after the special meetings and prior to the end of September.

3. FINANCIAL STATEMENT DETAILS (CONTINUED)


     During fiscal 1994, the Company provided $1,218,000 for expected losses on
the ultimate sale of certain inventories of raw material and finished goods.

     Other assets at July 2, 1995 included $426,000 of land and building in
Mexico held for sale.

4. FINANCIAL ARRANGEMENTS

     The Company has a $5,000,000 credit facility which expires on December 15,
1995. Interest on borrowings under this arrangement is payable monthly at prime
(9% at July 2, 1995). No amounts are outstanding under this arrangement at the
end of fiscal 1995.

     Long-term debt at July 2, 1995 and July 3, 1994 totals $1,114,000 and
$150,000, respectively.  Long-term debt at July 2, 1995 consists of lease
obligations with interest rates of 10.1% to 12.6% which require monthly
principal and interest payments until April 1998.  Additionally, the debt
agreement requires the Company to maintain certain minimum levels of current
assets, working capital and net worth and restricts the payment of dividends.
At July 2, 1995, all of the Company's retained earnings are available for the
payment of dividends.
 
5. INCOME TAXES

     Deferred tax assets and liabilities are determined based on temporary
differences between financial reporting and tax bases of assets and liabilities
and are measured using the enacted tax rates and laws that will be in effect
when the differences are expected to reverse.

     Significant components of the Company's deferred tax assets and liabilities
are as follows:

5. INCOME TAXES (CONTINUED)

     The valuation allowance for deferred tax assets of $573,000 was provided
because the realization of the benefits arising from foreign operating loss
carryforwards and other foreign temporary differences are not assured.  The

     Rent expense for the fiscal years 1995, 1994 and 1993 was $1,530,000,
$798,000 and $716,000, respectively. Included in equipment at July 2, 1995 is
equipment under capital leases aggregating $2,141,000. Accumulated amortization
with respect to the capital leases totaled $183,000 at July 2, 1995.  No
equipment under capital leases existed at July 3, 1994.

     Contingency - A legal action was instituted in February 1995 in which the
Company has been named as one of several defendants. The plaintiffs allege that
they have experienced physical harm and injury and other damages caused by
exposure to contaminants historically discharged from the former Potter
operation plant site located in Brookhaven, Lincoln County, Mississippi, which
the Company acquired in 1986 from Varian Associates. The Company is continuing
its analysis of the merits of the case; however, under any circumstances, the
Company believes that it is indemnified against any liability or expenses
relating to the action. The entities that the Company believes are required to
indemnify it have not to date acknowledged their obligations, and the Company
has instituted legal action to enforce its indemnification rights. The Company
cannot predict the level of expenses it will be required to incur to defend
itself in this action or to enforce its indemnification rights. While such
expenses will continue to be reflected in the Company's results of operations to
the extent that the Company is not reimbursed therefor, the Company believes
that it is entitled to be reimbursed for all expenses it has already incurred in
addition to being indemnified against any potential liability. The entities
with indemnity obligations to the Company have performed other obligations
relating to environmental issues at the former Potter operation plant sites.

8.  BUSINESS INFORMATION BY GEOGRAPHIC AREA

     The Company's operations consist of one business segment; the design,
manufacturing and marketing of electronic components and modules for leading
manufacturers of local area networks, digital telecommunications and data
processing equipment. Operations are conducted in the United States, Mexico
(through fiscal 1994), Europe and Asia. Transfers between geographic areas are
accounted for at prices that are generally above cost. The effects of such
transfers are eliminated in the consolidated financial statements.

     During the fiscal years ended 1995, 1994 and 1993 sales to one customer and
its subcontractors accounted for 18%, 24% and 29%, respectively, of consolidated
net sales. An additional customer accounted for 13% of consolidated sales in
fiscal 1995.

</TABLE>

     The reduction in identifiable United States assets in fiscal 1994 resulted
from the transfer of property, plant and equipment to Asia and the use of short-
term investments to fund operating and investing activities in Asia. Inventories
in the United States were also reduced during fiscal 1994 due to the shift in
production to Asia.

     Total export sales (sales by domestic operations to unaffiliated customers
outside the United States) from continuing operations were $7,376,000,
$2,196,000 and $4,251,000 for fiscal 1995, 1994 and 1993, respectively.

9. INCENTIVE AND RETIREMENT PLANS

     The Company's Board of Directors has an approved management incentive
compensation plan for officers and other key personnel which provides for
incentive compensation based on attainment of certain financial objectives. The
expense related to this incentive plan was $940,000 in fiscal 1995 and $404,000
in fiscal 1993. No incentive expense was incurred in fiscal 1994.

     The Company has adopted a deferred compensation and retirement plan which
covers certain full time employees. Under the plan, eligible employees may elect
salary reductions which are contributed to the plan and are eligible for
matching contributions by the Company of up to 2% of compensation after two
years of service and up to 4% of compensation after three years of service.
Participants are fully vested in their accounts. The aggregate contributions
made under the plan by the Company and charged to operations during fiscal 1995,
1994 and 1993 totaled $183,000, $210,000 and $205,000, respectively.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders
Pulse Engineering, Inc.

We have audited the accompanying consolidated balance sheets of Pulse
Engineering, Inc. as of July 2, 1995 and July 3, 1994, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the three years in the period ended July 2, 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Pulse
Engineering, Inc. at July 2, 1995 and July 3, 1994, and the consolidated results
of its operations and its cash flows for each of the three years in the period
ended July 2, 1995 in conformity with generally accepted accounting principles.

waiver of the conditions set forth in Article 6 (the "Closing Date").

               1.3  Corporate Effect of the Merger. At the Effective Time, the
                    ------------------------------
effect of the Merger shall be as provided in this Agreement and the applicable
provisions of the DGCL. Without limiting the generality of the foregoing, at the
Effective Time:

                    (a)  The separate corporate existence of Pulse shall cease
and Teco Sub shall continue as the surviving corporation (the "Surviving
Corporation").

                    (b)  The Certificate of Incorporation of Teco Sub as in
effect immediately prior to the Effective Time shall be the Certificate of
Incorporation of the Surviving Corporation.

                    (c)  The Bylaws of Teco Sub as in effect immediately prior
to the Effective Time shall be the Bylaws of the Surviving Corporation.

                    (d)  The directors and officers of Teco Sub immediately
prior to the Effective Time shall be the initial directors and officers of the
Surviving Corporation, each to hold
<PAGE>
 
office in accordance with the Certificate of Incorporation and By-laws of the
Surviving Corporation, in each case until their respective successors are duly
elected or appointed and qualified.

               1.4  Effect of the Merger on Capital Stock; Conversion of Pulse
                    ----------------------------------------------------------
Common Stock. At the Effective Time, by virtue of the Merger and without any
------------
action on the part of Teco Sub, Pulse or the holders of the securities of
either:

                    (a)  Subject to the other provisions of this Section 1.4,
each share of Class A voting common stock, par value $.01 per share, of Pulse
("Pulse Common Stock") issued and outstanding immediately prior to the Effective
Time (excluding any treasury shares and Dissenting Shares (as defined in Section
1.8)) shall be converted into (i) the right to receive .5812 shares of common
stock, $.125 par value ("Technitrol Common Stock"), of Technitrol (the "Exchange
Ratio"), (ii) the right to receive Eight Dollars and Fifty Cents ($8.50) in
cash, without interest (the "Per Share Cash Amount"), or (iii) the right to
receive a combination of shares of Technitrol Common Stock and cash determined
in accordance with Section 1.4(d), Section 1.4(e) or Section 1.4(f); provided,
however, that:

                         (A) If the average closing price of Technitrol Common
                         Stock on the American Stock Exchange (the "ASE") as
                         reported in The Wall Street Journal for the ten (10)
                         trading days immediately preceding the three (3)
                         business days preceding the Effective Time (the
                         "Average Closing Price") is less than $13 3/4, then (x)
                         the Exchange Ratio shall be adjusted upward to that
                         ratio which yields, based upon the Average Closing
                         Price, $8.00 per share of Pulse Common Stock and (y)
                         the Per Share Cash Amount shall remain unchanged; or

                         (B) If the Average Closing Price is greater than
                         $163/8, then (x) the Exchange Ratio shall be adjusted
                         downward to that ratio which yields, based upon the
                         Average Closing Price, $9.52 per share of Pulse Common
                         Stock and (y) the Per Share Cash Amount shall remain
                         unchanged.
                         
Further, if between the date of this Agreement and the Effective Time the
outstanding shares of Technitrol Common Stock or Pulse Common Stock shall have
been changed into a different number of shares or a different class, by reason
of a stock dividend, subdivision, reclassification, recapitalization, split,
combination or exchange of shares, the Exchange Ratio and the Per Share Cash
Amount shall be correspondingly adjusted to reflect such stock dividend,
subdivision, reclassification, recapitalization, split, combination or exchange
of shares.  Immediately after the Effective Time,  all shares of Pulse Common
Stock shall no longer be outstanding and shall automatically be canceled and
retired and shall cease to exist, and each certificate previously evidencing any
such shares shall thereafter represent the right to receive the Merger
Consideration (as defined in Section 1.5 (b)) except for Dissenting Shares which
shall be treated in accordance with Section 1.8.  The holders of such
certificates previously evidencing such shares of Pulse Common Stock outstanding
immediately prior to the Effective Time shall cease to have any rights with
respect to such shares of Pulse Common Stock except as otherwise provided herein
or by law.  Such certificates previously evidencing shares of Pulse Common Stock
shall be exchanged for (i) certificates evidencing whole shares of Technitrol
Common Stock issued in consideration therefor or (ii) the Per Share Cash Amount
multiplied by the number of shares previously evidenced by the canceled
certificate, in each 

                                       2
<PAGE>
 
case in accordance with the allocation procedures of this Section 1.4 and upon
the surrender of such certificates in accordance with the provisions of Section
1.5, without interest. No fractional shares of Technitrol Common Stock shall be
issued, and, in lieu thereof, a cash payment shall be made pursuant to Section
1.5(e).

                    (b)  Subject to Section 1.4(k) the maximum number of shares
of Pulse Common Stock to be converted into the right to receive cash in the
Merger (the "Cash Election Number") shall be fifty percent (50%) of the number
of shares of Pulse Common Stock outstanding immediately prior to the Effective
Time. Subject to Section 1.4(k) the maximum number of shares of Pulse Common
Stock to be converted into the right to receive Technitrol Common Stock in the
Merger (the "Stock Election Number") shall be fifty-five percent (55%) of the
number of shares of Pulse Common Stock outstanding immediately prior to the
Effective Time.

                    (c)  Subject to the allocation and election procedures set
forth in this Section 1.4, each record holder immediately prior to the Effective
Time of shares of Pulse Common Stock will be entitled (i) to elect to receive
cash for all of such shares (a "Cash Election"), (ii) to elect to receive
Technitrol Common Stock for all of such shares (a "Stock Election"), or (iii) to
indicate that such record holder has no preference as to the receipt of cash or
Technitrol Common Stock for such shares ( a "Non-Election"). All such elections
shall be made on a form designed for that purpose (a "Form of Election").
Holders of record of shares of Pulse Common Stock who hold such shares as
nominees, trustees or in other representative capacities (a "Representative")
may submit multiple Forms of Election, provided that any such Representative
certifies that each such Form of Election covers all the shares of Pulse Common
Stock held by such Representative for a particular beneficial owner.

                    (d)  If the aggregate number of shares covered by Cash
Elections (the "Cash Election Shares") exceeds the Cash Election Number, all
shares of Pulse Common Stock covered by Stock Elections (the "Stock Election
Share") and all shares of Pulse Common Stock covered by Non-Elections (the "Non-
Election Shares") shall be converted into the right to receive Technitrol Common
Stock, and the Cash Election Shares shall be converted into the right to receive
Technitrol Common Stock and cash in the following manner:

                    each Cash Election Share shall be converted into the right
                    to receive (i) an amount in cash, without interest, equal to
                    the product of (x) the Per Share Cash Amount and (y) a
                    fraction (the "Cash Fraction"), the numerator of which shall
                    be the Cash Election Number and the denominator of which
                    shall be the total number of Cash Election Shares, and (ii)
                    a number of shares of Technitrol Common Stock equal to the
                    product of (x) the Exchange Ratio and (y) a fraction equal
                    to one minus the Cash Fraction.

                    (e)  If the aggregate number of Stock Election Shares
exceeds the Stock Election Number, all Cash Election Shares and all Non-Election
Shares shall be converted into the right to receive cash, and all Stock Election
Shares shall be converted into the right to receive Technitrol Common Stock and
cash in the following manner:

                    each Stock Election Share shall be converted into the right
                    to receive (i) a number of shares of Technitrol Common Stock
                    equal to the product of (x) the Exchange Ratio and (y) a
                    fraction (the "Stock Fraction"), the numerator 

                                       3
<PAGE>
 
                    of which shall be the Stock Election Number and the
                    denominator of which shall be the total number of Stock
                    Election Shares, and (ii) an amount in cash, without
                    interest, equal to the product of (x) the Per Share Cash
                    Amount and (y) a fraction equal to one minus the Stock
                    Fraction.

                    (f)  In the event that neither Section 1.4(d) nor Section
1.4(e) above is applicable, all Cash Election Shares shall be converted into the
right to receive cash, all Stock Election Shares shall be converted into the
right to receive Technitrol Common Stock, and the Non-Election Shares, if any,
shall be converted into the right to receive Technitrol Common Stock and cash in
the following manner:

                    each Non-Election Share shall be converted into the right to
                    receive (i) a number of shares of Technical Common Stock
                    equal to the product of (x) the Exchange Ratio and (y) a
                    fraction (the "Non-Election Fraction"), which is the lesser
                    of one (1) or a fraction where the numerator shall be the
                    excess of the Stock Election Number over the total number of
                    Stock Election Shares and the denominator of which shall be
                    the aggregate of the Non-Election Shares and (ii) an amount
                    in cash, without interest, equal to the product of (x) the
                    Per Share Cash Amount and (y) a fraction equal to one minus
                    the Non-Election Fraction.

                    (g)  Elections shall be made by holders of Pulse Common
Stock by mailing to the Exchange Agent (as defined below) a Form of Election. To
be effective, a Form of Election must be properly completed, signed and
submitted to the Exchange Agent and accompanied by the certificates representing
the shares of Pulse Common Stock as to which the election is being made (or by
an appropriate guarantee of delivery of such certificates by a commercial bank
or trust company in the United States or a member of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.
(the "NASD")). Technitrol will have the discretion, which it may delegate in
whole or in part to the Exchange Agent, to determine whether Forms of Election
have been properly completed, signed and submitted or revoked and to disregard
immaterial defects in Forms of Election. The decision of Technitrol (or the
Exchange Agent) in such matters shall be conclusive and binding. Neither
Technitrol nor the Exchange Agent will be under any obligation to notify any
person of any defect in a Form of Election submitted to the Exchange Agent. The
Exchange Agent shall also make all computations contemplated by this Section 1.4
and all such computations shall be conclusive and binding on the holders of
Pulse Common Stock (absent manifest error).

                    (h)  For the purposes hereof, a holder of Pulse Common Stock
who does not submit a Form of Election which is received by the Exchange Agent
prior to the Election Deadline (as hereinafter defined) shall be deemed to have
made a Non-Election. If Technitrol or the Exchange Agent shall determine that
any purported Cash Election or Stock Election was not properly made, such
purported Cash Election or Stock Election shall be deemed to be of no force and
effect and the shareholder making such purported Cash Election or Stock Election
shall for purposes hereof, be deemed to have made a Non-Election.

                    (i)  Technitrol and Pulse shall each use its best efforts to
mail the Form of Election to all persons who become holders of Pulse Common
Stock during the period between the record date for the Pulse and Technitrol
Stockholders' Meeting (as defined in Section 2.20) and 10:00 

                                       4
<PAGE>
 
a.m. New York time, on the date seven (7) calendar days prior to the anticipated
Effective Time and to make the Form of Election available to all persons who
become holders of Pulse's Common Stock subsequent to such day and no later than
the close of business on the business day prior to the Effective Time. A Form of
Election must be received by the Exchange Agent by the close of business on the
last business day prior to the Effective Time (the "Election Deadline") in order
to be effective. All elections may be revoked until the Election Deadline. Upon
request or revocation of an election by a holder of Pulse Common Stock, the
Exchange Agent shall promptly return all share certificates to such holder.

                    (j)  Each share of Pulse Common Stock held in the treasury
of Pulse and each share of Pulse Common Stock owned by any direct or indirect
wholly owned subsidiary of Pulse or by Technitrol or any direct or indirect
subsidiary of Technitrol (except shares owned by the Technitrol, Inc. Retirement
Plan immediately prior to the Effective Time) shall be canceled and extinguished
without any conversion thereof and no payment shall be made with respect
thereto.

                    (k)  If the tax opinions referred to in Section 6.1(d)
cannot be rendered (as reasonably determined, respectively, by Stradley, Ronon,
Stevens & Young and by Pillsbury Madison & Sutro) as a result of the Merger
potentially failing to satisfy continuity of interest requirements under
applicable federal income tax principles relating to reorganizations under
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"),
then the Stock Election Number shall be increased, and the Cash Election Number
shall be decreased, to the minimum extent necessary to enable the tax opinions
to be rendered.

               1.5  Exchange of Certificates.
                    ------------------------ 

                    (a)  Exchange Agent. At or prior to the Effective Time,
                         --------------   
Technitrol shall deposit, or shall cause to be deposited, with a bank or trust
company designated by Technitrol (the "Exchange Agent"), for the benefit of
holders of shares of Pulse Common Stock, for exchange in accordance with this
Agreement, (i) certificates evidencing such number of shares of Technitrol
Common Stock equal to the Exchange Ratio multiplied by the Stock Election Number
and (ii) cash in the amount equal to the Per Share Cash Amount multiplied by the
Cash Election Number (such certificates for shares of Technitrol Common Stock,
together with any dividends or distributions with respect thereto and cash,
being hereinafter referred to as the "Exchange Fund"). The Exchange Agent shall,
pursuant to irrevocable instructions, deliver the Technitrol Common Stock and
cash contemplated to be issued pursuant to Section 1.4 out of the Exchange Fund.
Except as contemplated by Section 1.5 hereof, the Exchange Fund shall not be
used for any other purpose.

                    (b)  Exchange Procedures. Promptly after the Effective Time,
                         -------------------  
Technitrol will cause the Exchange Agent to mail to each holder of record of a
certificate or certificates which immediately prior to the Effective Time
evidenced Non-Election Shares (other than Dissenting Shares), (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the certificates shall pass, only upon proper delivery of the
certificates to the Exchange Agent and shall be in such form and have such other
provisions as Technitrol may reasonably specify) and (ii) instructions for use
in effecting the surrender of the certificates in exchange for the Merger
Consideration. Each holder of a certificate formerly representing Pulse Common
Stock (a "Certificate") who surrenders or has surrendered such Certificate (or
an affidavit pursuant to Section 1.9), together with duly executed transmittal
materials (such as those included in the Election Form) shall, upon acceptance
thereof (which Technitrol shall cause to occur promptly), be entitled to receive

                                       5
<PAGE>
 
in exchange therefor (A) certificates evidencing that number of whole shares of
Technitrol Common Stock which such holder has the right to receive in respect of
the shares of Pulse Common Stock formerly evidenced by such Certificate in
accordance with Section 1.4, (B) cash to which such holder is entitled to
receive in accordance with Section 1.4, (C) cash in lieu of fractional shares of
Technitrol Common Stock to which such holder is entitled pursuant to Section
1.5(e), and (D) any dividends or other distributions to which such holder is
entitled pursuant to Section 1.5(c), (the shares of Technitrol Common Stock,
dividends, distributions and cash described in clauses (A), (B), (C) and (D)
being collectively, the "Merger Consideration") and the Certificate so
surrendered shall forthwith be canceled. In the event of a transfer of ownership
of Pulse Common Stock which is not registered in the transfer records of Pulse,
a certificate evidencing the proper number of Technitrol Common Stock and/or
cash may be issued and/or paid in accordance with this Agreement to a transferee
if the Certificate evidencing such shares of Pulse Common Stock is presented to
the Exchange Agent, accompanied by all documents required to evidence and effect
such transfer and by evidence that any applicable stock transfer taxes have been
paid. Until surrendered as contemplated by this Section 1.5, each Certificate
shall be deemed at any time after the Effective Time to evidence only the right
to receive upon such surrender the Merger Consideration.

                    (c)  Distributions with Respect to Unexchanged Shares of
                         ---------------------------------------------------
Technitrol Common Stock. No dividends or other distributions declared or made
-----------------------
after the Effective Time with respect to Technitrol Common Stock with a record
date after the Effective Time shall be paid to the holder of any unsurrendered
Certificate with respect to the shares of Technitrol Common Stock evidenced
thereby and no other part of the Merger Consideration shall be paid to any such
holder, until the holder of such Certificate shall surrender such Certificate
(or an affidavit pursuant to Section 1.9). Subject to the effect of applicable
laws, following surrender of any such Certificate, there shall be paid to the
holder of the certificates evidencing whole shares of Technitrol Common Stock
issued in exchange therefor, without interest, (i) promptly, the amount of any
cash payable with respect to a fractional share of Technitrol Common Stock to
which such holder is entitled pursuant to Section 1.5(e) and the amount of
dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole shares of Technitrol Common Stock,
and (ii) at the appropriate payment date, the amount of dividends or other
distributions, with a record date after the Effective Time but prior to
surrender and a payment date occurring after surrender, payable with respect to
such whole shares of Technitrol Common Stock. No interest shall be paid on the
Merger Consideration.

                    (d)  No Further Rights in Pulse Common Stock. All shares of
                         ---------------------------------------
Technitrol Common Stock issued and cash paid upon conversion of the shares of
Pulse Common Stock in accordance with the terms hereof shall be deemed to have
been issued or paid in full satisfaction of all rights pertaining to such shares
of Pulse Common Stock.

                    (e)  No Fractional Shares. No certificates or scrip
                         --------------------
evidencing fractional shares of Technitrol Common Stock shall be issued upon the
surrender for exchange of Certificates, and such fractional share interests will
not entitle the owner thereof to vote or to any rights of a stockholder of
Technitrol. In lieu of any such fractional shares, each holder of Pulse Common
Stock promptly upon surrender of a Certificate for exchange pursuant to this
Section 1.5 shall be paid an amount in cash (without interest), rounded to the
nearest cent, determined by multiplying (A) the Average Closing Price by (B) the
fractional interest to which such holder would otherwise be entitled (after
taking into account all shares of Pulse Common Stock then held of record by such
holder).

                    (f)  Termination of Exchange Fund. Any portion of the
                         ---------------------------- 
Exchange Fund which remains undistributed to the holders of Pulse Common Stock
for six (6) months after the Effective Time shall be delivered to Technitrol,
upon demand, and any holders of Pulse Common Stock who have not theretofore
complied with this Article 1 shall thereafter look only to Technitrol for the
Merger Consideration to which they are entitled.

                    (g)  No Liability. Notwithstanding anything to the contrary
                         ------------
in this Article 1, no party hereto shall be liable to any holder of shares of
Pulse Common Stock for any shares of Technitrol Common Stock, (or dividends or
distributions with respect thereto) or cash delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

                    (h)  Withholding Rights. Technitrol shall be entitled to
                         ------------------
deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of shares of Pulse Common Stock such amounts as
Technitrol is required to deduct and withhold with respect to the making of such
payment under the Code, or any provision of state, local or foreign tax law. To
the extent that amounts are so withheld by Technitrol, such withheld amounts
shall be treated for all purposes of this Agreement as having been paid to the
holder of the shares of Pulse Common Stock in respect of which such deduction
and withholding was made by Technitrol.

               1.6  Stock Transfer Books. At the Effective Time, the stock
                    --------------------
transfer books of Pulse shall be closed and there shall be no further
registration of transfers of shares of Pulse Common Stock thereafter on the
records of Pulse. On or after the Effective Time, any certificates presented to
the Exchange Agent or Technitrol for any reason shall be converted into the
Merger Consideration.

               1.7  Stock Options; Payment Right. At the Effective Time,
                    ----------------------------  
Pulse's obligations with respect to each outstanding Stock Option (as defined in
Section 2.2) shall be assumed by Technitrol unless the parties shall agree upon
an alternative method of handling such Stock Options based upon tax, accounting
or securities law considerations. The Stock Options so assumed by Technitrol
shall continue to have, and be subject to, the same terms and conditions set
forth in the stock option plans and agreements pursuant to which such Stock
Options were issued as in effect immediately prior to the Effective Time, except
that (a) such Stock Options shall be exercisable for that number of whole shares
of Technitrol Common Stock equal to the product of the number of shares of Pulse
Common Stock covered by the Stock Option immediately prior to the Effective Time
multiplied by the Exchange Ratio rounded up to the nearest whole number of
shares of Technitrol Common Stock, and (b) the per share exercise price for the
shares of Technitrol Common Stock issuable upon the exercise of such assumed
Stock Option shall be equal to the quotient determined by dividing the exercise
price per share of Pulse Common Stock specified for such Stock Option under the
applicable Stock Option plan or agreement immediately prior to the Effective
Time by the Exchange Ratio rounding the resulting exercise price down to the
nearest whole cent. The date of grant shall be the date on which the Stock
Option was originally granted. Technitrol shall (i) reserve for issuance the
number of shares of Technitrol Common Stock that will become issuable upon the
exercise of such Stock Options pursuant to this Section 1.7 and (ii) at the
Effective Time execute a document evidencing the assumption by Technitrol of
Pulse's obligations with respect thereto under this Section 1.7. Nothing in this
Section 1.7 shall affect the schedule of vesting (or the acceleration thereof)
with respect to the Stock Options to be assumed by Technitrol as provided in
this Section 1.7. As soon as practicable after the Effective Time, Technitrol
shall file a registration statement on Form S-8 (or any successor form), or
another appropriate form with respect to the shares of Technitrol Common Stock
subject to such options and shall use its best efforts to maintain the

                                       7
<PAGE>
 
effectiveness of such registration statement or registration statements (and
maintain the current status of the prospectus or prospectuses contained therein)
for so long as such options remain outstanding. With respect to those
individuals who subsequent to the Merger will be subject to the reporting
requirements under Section 16(a) the Securities Exchange Act of 1934, as amended
(the 'Exchange Act'), where applicable, Technitrol, to the extent legally
permissible, shall administer the Stock Option plans assumed pursuant to this
Section 1.7 in a manner that complies with Rule 16b-3 promulgated under the
Exchange Act to the extent the applicable Pulse Stock Option Plan complied with
such rule prior to the Merger.

               1.8  Dissenting Shares.
                    ----------------- 

                    (a)  Notwithstanding any other provisions of this Agreement
to the contrary, shares of Pulse Common Stock that are outstanding immediately
prior to the Effective Time and which are held by stockholders who shall have
not voted in favor of the Merger or consented thereto in writing and who shall
have demanded properly in writing appraisal for such shares in accordance with
Section 262 of the DGCL (collectively, the "Dissenting Shares") shall not be
converted into or represent the right to receive the Merger Consideration. Such
stockholders shall be entitled to receive payment of the appraised value of such
shares of Pulse Common Stock held by them in accordance with the provisions of
such Section 262, except that all Dissenting Shares held by stockholders who
shall have failed to perfect or who effectively shall have withdrawn or lost
their rights to appraisal of such shares of Pulse Common Stock under such
Section 262 shall thereupon be deemed to have been converted into and to have

                    REPRESENTATIONS AND WARRANTIES OF PULSE

                Pulse represents and warrants to Technitrol and Teco Sub,
subject to the exceptions specifically disclosed in writing in the disclosure
letter supplied by Pulse to Technitrol (the "Pulse Schedules") and dated as of
the date hereof, as set forth below. As used in this Article 2 and in Article 3,
the term "Material Adverse Effect" with respect to a party means a material
adverse effect on the business, assets (including intangible assets), financial
condition, or results of operations of such party and its subsidiaries, taken as
a whole.

              2.1  Organization of Pulse. Pulse and each of its direct and
indirectly owned subsidiaries (a correct and complete list of which
subsidiaries, together with their states or jurisdiction of incorporation, is
set forth in the Pulse Schedules; each individually a "Subsidiary" and
collectively the "Subsidiaries") is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation, has the corporate power to own, lease and operate its property
and to carry on its business as now being conducted and as proposed to be
conducted, and is duly qualified to do business and in good standing as a
foreign corporation in each jurisdiction in which the failure to be so qualified
would have a Material Adverse Effect on Pulse. Pulse owns, directly or
indirectly through one or more Subsidiaries, 100% of the capital stock of each
of its Subsidiaries. Except as set forth in Pulse SEC Reports (as defined below
in Section 2.5), Pulse does not directly or indirectly own any equity or similar
interest in, or any interest convertible into or exchangeable or exercisable for
any interest in, any corporation, partnership, joint venture or other business
association or entity other than the securities of any publicly-traded entity
held for investment only and constituting less than 5% of the outstanding
capital stock of any such entity. Pulse has delivered or made available to
Technitrol a true and correct list of all entities in which it has less than 5%
of the outstanding capital stock. Pulse has delivered or made available to
counsel for Technitrol a true and correct copy of the Certificate of
Incorporation and Bylaws of Pulse and similar governing instruments of its

              2.13   Governmental Authorization. Pulse holds all permits,
                     --------------------------
licenses, variances, exemptions, orders and approvals of all Governmental
Entities which are material to the operation of Pulse's business as currently
conducted (the "Pulse Permits"). Pulse is in material compliance with the terms
of Pulse Permits. Except as disclosed in Pulse's SEC Reports filed prior to the
date of this Agreement, the business of Pulse is not being conducted in
violation of any law, ordinance or regulation of any Governmental Entity, except
for violations or possible violations which individually or in the aggregate are
not, and insofar as reasonably can be foreseen in the future will not be,
material to Pulse. As of the date of this Agreement, no investigation or review
by any Governmental Entity with respect to Pulse is pending or, to the knowledge
of Pulse, threatened, nor has any Governmental Entity indicated an intention to
conduct the same, other than, in each case, those the outcome of which, as far
as reasonably can be foreseen, will not be material. There are no products now
being manufactured, assembled or sold by Pulse which at the date hereof would
require any approval of any governmental body, whether federal, state, local or
foreign for the purpose for which they are being manufactured, assembled or sold
by Pulse, for which such approval has not been obtained. All products now being
commercially distributed by Pulse in any jurisdiction meet the applicable legal
requirements of such jurisdiction and all requisite governmental approvals have
been duly obtained and are in full force and effect, and there is no basis known
to Pulse for any governmental body to deny or rescind any approval for any of
their commercially distributed products for the purpose for which they are being
manufactured, assembled or sold by Pulse or for any products that Pulse proposes
to commercially distribute in the future. There is no action or proceeding by
any governmental body pending or, to the knowledge of Pulse, threatened against
Pulse, and no such proceeding was brought at any time in the past and, to the
knowledge of Pulse, there is no basis for any such action or proceeding.

              2.14  Litigation.  There is no action, suit or proceeding, claim,
                    ----------
arbitration or investigation pending, or as to which Pulse or any of its
Subsidiaries has received any notice of assertion nor, to Pulse's knowledge, is
there a reasonable basis to expect such notice of assertion against Pulse or any
of its Subsidiaries which, if determined adversely to Pulse or any of its
Subsidiaries reasonably would be expected to be material to Pulse, or which in
any manner challenges or seeks to prevent, enjoin, alter or delay any of the
transactions contemplated by this Agreement.

respects with all applicable provisions of the Consolidated Omnibus Budget
Reconciliation Act of 1985 ("COBRA") and has no material obligations with
respect to any former employees or qualifying beneficiaries thereunder. Except
as is not material to Pulse's business and operations, neither Pulse nor any of
its Subsidiaries has given to or received from any current employee of Pulse or
any of its Subsidiaries notice of termination of employment.

(ii) Pulse has maintained all Employee Plans and Benefit Arrangements in
compliance in all material respects with the requirements prescribed by any and
all applicable statutes (including ERISA and the Code), orders, or governmental
rules and regulations currently in effect with respect thereto (including all

                    (d)  None of the following now exists or has existed within

adequately provided for on the audited Pulse Financials for the most recently-
ended fiscal year. All accruals thereon (including, where appropriate,
proportional accruals for partial periods) have been made in accordance with
generally accepted accounting principles consistently applied on a reasonable
basis. There has been no amendment, written interpretation or announcement
(whether or not written) by Pulse with respect to, or change in employee
participation or coverage under, any Employee Plan or Benefit Arrangement that

premiums or other payments due from Pulse or any of its Subsidiaries to (or
under) any such plan have been fully paid or adequately provided for on the
audited Pulse Financials for the most recently-ended fiscal year. All accruals
thereon (including, where appropriate, proportional accruals for partial
periods) have been made in accordance with generally accepted accounting
principles consistently applied on a reasonable basis.

and at the time it becomes effective under the Securities Act, contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein not
misleading. The information to be supplied by Pulse for inclusion in the joint

stockholders of Technitrol in connection with the meeting of Pulse's
stockholders to consider the Merger (the "Pulse Stockholders' Meeting") and the

supplemented is referred to herein as the "Proxy Statement") shall not, on the
date the Proxy Statement is first mailed to Pulse's stockholders and
Technitrol's stockholders, at the time of Pulse's Stockholders' Meeting or
Technitrol Stockholders' Meeting and at the Effective Time, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they

                                      20

are made, not false or misleading; or omit to state any material fact necessary
to correct any statement in any earlier communication with respect to the
solicitation of proxies for Pulse Stockholders' Meetings or Technitrol
Stockholders' meeting which has become false or misleading. To Pulse's best
knowledge at the time the Proxy Statement is mailed to the stockholders of Pulse
and Technitrol, the Proxy Statement will comply as to form in all material
respects with the provisions of the Exchange Act and the rules and regulations
thereunder. If at any time prior to the Effective Time any information relating

Pulse which should be set forth in an amendment to the Registration Statement or

Notwithstanding any of the foregoing, Pulse makes no representation or warranty
with respect to any information supplied by Technitrol or Teco Sub which is
contained in any of the foregoing documents.

1994 regarding the business of Pulse, including product and historical financial
information, did not, to the actual knowledge of Pulse's executive officers,
contain any material misrepresentation of a material fact or omit any
information necessary to make the information provided not materially
misleading. The written projections of Pulse's future financial performance
provided by Pulse to Technitrol were prepared in good faith based on assumptions
believed by Pulse to be reasonable; however no other representation is made or
to be implied concerning such projections.

               2.23  Fairness Opinion. Pulse has received a written opinion
                     ----------------
from Oppenheimer & Co., Inc. ("Oppenheimer"), dated as of the date hereof, to
the effect that the Merger Consideration to be received by the holders of Pulse
Common Stock is fair from a financial point of view and has delivered to
Technitrol a copy of such opinion.

a result of the execution and delivery of this Agreement or the performance of
its obligations hereunder, in violation of any agreement to which Technitrol is
a party and pursuant to which Technitrol or any other person is authorized to

                     -------------------------------------- 

                     (a)   Each party shall afford the other party and its
accountants, counsel and other representatives reasonable access during normal
business hours during the period prior to the Effective Time to all information
concerning the business, including the status of product development efforts,
properties and personnel of such party as the other party may reasonably
request. No information or knowledge obtained in any investigation pursuant to
this Section 5.3 shall affect or be deemed to modify any representation or
warranty contained herein or the conditions to the obligations of the parties to
consummate the Merger.

                     (b)   The parties acknowledge that Technitrol and Pulse
have previously executed a confidentiality agreement dated November 16, 1994
(the "Confidentiality Agreement"), which Confidentiality Agreement shall
continue in full force and effect in accordance with its terms.

               5.4   No Solicitation.
                     --------------- 

                     (a)   From and after the date of this Agreement until the
Effective Time, Pulse and its subsidiaries will not, and will use its reasonable
best efforts to cause their respective directors, officers, employees,
representatives, investment bankers, agents and affiliates not to, directly or
indirectly, (i) initiate, solicit or encourage submission of any inquiries,
proposals or offers by any person, entity or group (other than Technitrol, Teco
Sub and their affiliates, agents and representatives) relating to any
Acquisition Proposal, or (ii) participate in any discussions or negotiations
with, or disclose any non-public information concerning Pulse or any of its
subsidiaries to, or afford any access to the properties, books or records of
Pulse or any of its subsidiaries to, or otherwise assist, facilitate or
encourage, or enter into any agreement or understanding with, any person, entity
or group (other than Technitrol, Teco Sub and their affiliates, agents and
representatives) in connection with any Acquisition Proposal. For the purposes
of this Agreement, an "Acquisition Proposal" shall mean any proposal relating to
the possible acquisition of (i) Pulse (whether by way of merger or otherwise),
(ii) all or a substantial portion of the assets of Pulse or (iii) a substantial
portion of the equity securities of Pulse (except by conversion or exercise of
currently outstanding securities). In addition, subject to the other provisions
of this Section 5.4, from and after the date of this Agreement until the
Effective Time, Pulse and its subsidiaries will not, and will cause

                                      32
<PAGE>
 
their respective directors, officers, employees, representatives, investment
bankers, agents and affiliates not to, directly or indirectly, make or authorize
any statement, recommendation or solicitation in support of any Acquisition
Proposal made by any person, entity or group (other than Technitrol and/or Teco
Sub).

                     (b)   Notwithstanding the provisions of Paragraph (a)
above, prior to the Effective Time, Pulse may, to the extent the Board of
Directors of Pulse determines in good faith, after consultation with outside
legal counsel, that the Board's fiduciary duties under applicable law require it
to do so, participate in discussions or negotiations with, and, subject to the
requirements of paragraph (c) below, furnish information to any person, entity
or group after such person, entity or group shall have delivered to Pulse in
writing, an unsolicited bona fide Acquisition Proposal which the Board of
Directors of Pulse in its good faith reasonable judgment determines, after
consultation with its independent advisors, would result in a transaction more
favorable to the stockholders of Pulse than the Merger and for which financing,
to the extent required, is then committed or which, in the good faith reasonable
judgment of the Board of Directors of Pulse (based upon the advice of
independent advisors), is reasonably capable of being financed by such person,
entity or group and which is probable to be consummated in accordance with its
terms (a "Superior Proposal"). In addition, notwithstanding the provisions of
paragraph (a) above, in connection with a possible Acquisition Proposal, Pulse
may refer any third party to this Section 5.4 or make a copy of this Section 5.4
available to a third party.

                     (c)   Pulse may furnish information with respect to a
Superior Proposal only if Pulse (i) first notifies Technitrol of the Information
proposed to be disclosed, (ii) first complies with the provisions of paragraph
(e), below and (iii) provides such information pursuant to a confidentiality
agreement at least as restrictive as the Confidentiality Agreement entered into
by Technitrol.

                     (d)   In the event Pulse receives a Superior Proposal,
nothing contained in this Agreement shall prevent the Board of Directors of
Pulse from approving such Superior Proposal or recommending such Superior
Proposal to Pulse's stockholders, if the Board determines in good faith, after
consultation with outside legal counsel, that such action is required by its
fiduciary duties under applicable law; in such case, the Board may amend or
withdraw its recommendation of the Merger. Subject to the right of termination
set forth in Section 7.1, except to the extent expressly set forth in this
Section 5.4, nothing shall relieve Pulse from complying with all other terms of
this Agreement.

                     (e)   Pulse will (i) notify Technitrol if any inquiry or
proposal is made or any information or access is requested in connection with an
Acquisition Proposal or potential Acquisition Proposal and (ii) promptly
communicate to Technitrol the terms and conditions of any such Acquisition
Proposal or potential Acquisition Proposal or inquiry and the identity of the
offeror or potential offeror.

                     (f)   Nothing contained in this Section 5.4 shall prevent
Pulse or its Board of Directors from complying with the provisions of Rule 14e-
2(a) and 14d-9 promulgated under the Exchange Act.

expenses incurred in connection with this Agreement and the transactions
contemplated hereby, shall be paid by the party incurring such expenses, whether
or not the Merger is consummated; provided, however, that Technitrol and Pulse

financial advisor's fees, incurred in connection with the printing and filing of
the Registration Statement (including financial statements and exhibits) and any
amendments or supplements thereto.

                     (b)   If this Agreement is terminated by Technitrol

reasonable out-of-pocket expenses, including but not limited to attorney's fees,
accounting fees, financial printer expenses, filing fees and fees and expenses
of financial advisors incurred in connection with this Agreement and the Merger

If this Agreement is terminated (i) pursuant to Section 7.1(c)(i), or (ii)
pursuant to Section 7.1(c)(iii) and Technitrol shall not have delivered to Pulse
on or before June 30, 1995 a commitment letter from a reputable lending
institution for the financing described in Section 6.3(f), then Technitrol shall
pay Pulse's Out Of Pocket Expenses, not to exceed One Million Dollars
($1,000,000.00), incurred in connection with this Agreement and the Merger. If
(1) Pulse's Board of Directors adversely amends, withholds or withdraws its
recommendation of the Merger or (2) Pulse's stockholders do not approve the
Merger at Pulse's Stockholders' Meeting, then, provided that Technitrol is not
then in material breach of the terms of this Agreement, Pulse shall pay
Technitrol's Out of Pocket Expenses, not to exceed One Million Dollars
($1,000,000.00) upon written request therefor; provided, however, that any
amounts paid to Technitrol in the event of clause (1) or (2) shall reduce, on a
dollar-for-dollar basis, the amount, if any, payable by Pulse to Technitrol
pursuant to Section 5.6 hereof. If (A) Technitrol's Board of Directors adversely
amends, withholds or withdraws its recommendation of the Merger or (B)
Technitrol's stockholders do not approve the Merger at the Technitrol
Stockholder's Meeting, then, provided that Pulse is not then in material breach
of the terms of this Agreement, Technitrol shall pay Pulse's Out Of Pocket
Expenses, not to exceed One Million Dollars ($1,000,000.00) upon written request
therefor. Notwithstanding the foregoing, nothing contained herein shall relieve
any party from liability for any breach of this Agreement.

               5.6   Break-Up Fee.  If for any reason:
                     ------------                     

                     (a) the Board of Directors accepts a Superior Proposal or
recommends a Superior Proposal for Pulse's stockholders, or

                     (b) (i) the Board of Directors of Pulse adversely amends,
withholds or withdraws its recommendation that Pulse's stockholders approve the
Merger, (ii) the stockholders of Pulse fail to approve the Merger prior to
September 30, 1995, or (iii) there are Dissenting Shareholders representing
fifteen percent (15%) or more of the Pulse shares outstanding on the record date
for the Pulse Stockholders' Meeting and, within nine months following the
occurrence of an event set forth in any of clauses (i), (ii) or (iii), Pulse
merges with another Person, issues stock representing a 40% or greater voting
interest in Pulse to another Person, transfers more than 50% of its assets to
another Person or enters into an option, agreement or letter of intent to do any
of the foregoing or to do any other arrangement intended to transfer Pulse or
control of Pulse to such other Person, or to the stockholders of Pulse, in
response to a tender offer or exchange offer by any person tender shares

materially breached any of the representations, warranties, covenants or
agreements made on its part such that either of the conditions set forth in
Sections 6.2(a) or 6.2(b) will not be satisfied, Pulse shall pay to Technitrol,

available funds to an account designated by Technitrol. "Person" means any

                     ----------------------------------------- 

                     (a)   The Articles of Incorporation and By-Laws of Teco Sub
shall contain the provisions with respect to indemnification set forth in the
Articles of Incorporation and By-Laws of Pulse on the date of this Agreement,
which provisions shall not be amended, repealed, or otherwise modified for a
period of six years after the Effective Time in any manner that would adversely
affect the rights thereunder of individuals who at any time prior to the
Effective Time were directors or officers of Pulse in respect of actions or
omissions occurring at or prior to the Effective Time (including, without
limitation, the transactions contemplated by this Agreement), unless such
modification is required by law.

                     (b)   From and after the Effective Time, the Surviving
Corporation shall indemnify, defend and hold harmless the present and former
officers and directors of Pulse (collectively, the "Indemnified Parties")
against all losses, expenses, claims, damages, liabilities or amounts that are
paid in settlement of, with the approval of Technitrol and the Surviving
Corporation (which approval shall not unreasonably be withheld), or otherwise in
connection with any claim, action, suit, proceeding or investigation (a
"Claim"), based in whole or in part on the fact that such person is or was a
director or officer of Pulse and arising out of actions or omissions occurring
at or prior to the Effective Time (including, without limitation, the
transactions contemplated by this Agreement), in each case to the full extent
permitted under the DGCL (and shall pay expenses in advance of the final
disposition of any such action or proceeding to each Indemnified Party to the

                                      36
<PAGE>
 
fullest extent permitted under the DGCL, upon receipt from the Indemnified
Party to whom expenses are advanced of the undertaking to repay such advances
contemplated by Section 145 of the DGCL). Technitrol shall guarantee the
Surviving Corporation's obligations pursuant to this Section 5.15(b).

                     (c)   Without limiting the foregoing, in the event any
Claim is brought against any Indemnified Party (whether arising before or after
the Effective Time) after the Effective Time (i) the Indemnified Parties may
retain Pulse's regularly engaged independent legal counsel, or other independent
legal counsel satisfactory to them provided that such other counsel shall be
reasonably acceptable to Technitrol and the Surviving Corporation, (ii) the
Surviving Corporation shall pay all reasonable fees and expenses of such counsel
for the Indemnified Parties promptly as statements therefor are received and
(iii) the Surviving Corporation will use its reasonable best efforts to assist
in the vigorous defense of any such matter, provided that the Surviving
Corporation shall not be liable for any settlement of any Claim effected without
its written consent, which consent shall not be unreasonably withheld. Any
Indemnified Party wishing to claim indemnification under this Section 5.15, upon
learning of any such Claim, shall notify the Surviving Corporation (although the
failure so to notify the Surviving Corporation shall not relieve the Surviving
Corporation from any liability which the Surviving Corporation may have under
this Section 5.15 except to the extent such failure prejudices the Surviving
Corporation), and shall deliver to the Surviving Corporation the undertaking
contemplated by Section 145 of the DGCL. The Indemnified Parties as a group may
retain one law firm (in addition to local counsel) to represent them with
respect to each such matter unless there is, under applicable standards of
professional conduct (as determined by counsel to the Indemnified Parties), a
conflict on any significant issue between the positions of any two or more
Indemnified Parties, in which event, such additional counsel as may be required
may be retained by the Indemnified Parties.

                     (d)   For a period of two years after the Effective Time,
Technitrol shall cause to be maintained in effect the current policies of
directors and officers' liability insurance maintained by Pulse (provided that

of, and shall be enforceable by, the Indemnified Parties, their heirs and

merged with and into Teco Sub (the "Merger"). Capitalized terms used herein and

          As a result of the Merger, I may receive shares of common stock, par 
value $0.125 per share, of Technitrol ("Technitrol Common Stock"). I would 
receive such shares in exchange for shares owned by me of common stock, par 
value $0.01 per share, of the Company.

          I represent, warrant and covenant to Technitrol that, in connection 
with the Merger, I will elect a Stock Election for each share of Pulse Common 
Stock for which I am the record holder immediately prior to the Effective Time.

          I represent, warrant and covenant to Technitrol that in the event I 
receive any Technitrol Common Stock as a result of the Merger:

          A.  I shall not make any sale, transfer or other disposition of
          Technitrol Common Stock in violation of the Act or the Rules and
          Regulations.
   
<PAGE>
 
          B.  I have carefully read this letter and the Agreement and discussed 
          the requirements of such documents and other applicable limitations 
          upon my ability to sell, transfer or otherwise dispose of Technitrol 
          Common Stock to the extent I felt necessary with my counsel or counsel
          for the Company.

          C.  I have been advised that the issuance of Technitrol Common Stock 
          to me pursuant to the Merger will be registered with the Commission 
          under the Act on a Registration Statement on Form S-4. However, I have
          also been advised that, since at the time the Merger is to be
          submitted for a vote of the stockholders of the Company, I may be 
          deemed to have been an affiliate of the Company and the distribution 
          by me of Technitrol Common Stock has not been registered under the 
          Act, I may not sell, transfer or otherwise dispose of Technitrol 
          Common Stock issued to me in the Merger unless (i) such sale, transfer
          or other disposition is registered under the Act, (ii) such sale, 
          transfer or other disposition is made in conformity with the volume
          and other limitations of Rule 145 promulgated by the Commission under
          the Act, or (iii) in the opinion of counsel reasonably acceptable to 
          Technitrol, such sale, transfer or other disposition is otherwise 
          exempt from registration under the Act.

          D.  I understand that Technitrol is under no obligation to register 
          the sale, transfer or other disposition of Technitrol Common Stock by 
          me or on my behalf under the Act or to take any other action necessary
          in order to make compliance with an exemption from such registration 
          available except as provided herein.

          E.  I also understand that stop transfer instructions will be given to
          Technitrol's transfer agents with respect to Technitrol Common Stock
          issued to me pursuant to the Merger and that there will be placed on
          the certificates for such Technitrol Common Stock issued to me, or any
          substitutions therefor, a legend stating in substance:


              "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A 
              TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT
              OF 1933 APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY 
              ONLY BE TRANSFERRED IN ACCORDANCE 

                                      -2-

              WITH THE TERMS OF AN AGREEMENT DATED MAY __, 1995 BETWEEN THE
              REGISTERED HOLDER HEREOF AN TECHNITROL, INC., A COPY OF WHICH
              AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICES OF TECHNITROL,
              INC."

          F.  I also understand that unless the transfer by me of Technitrol
          Common Stock issued to me pursuant to the Merger has been registered
          under the Act or is made in conformity with the provisions of Rule
          145, Technitrol reserves the right to put the following legend on the
          certificates issued to my transferee:

              "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
              REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND WERE
              ACQUIRED FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION
              TO WHICH RULE 145 PROMULGATED UNDER THE ACT APPLIES. THE SHARES
              HAVE BEEN ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE
              IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF
              THE ACT AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED
              EXCEPT IN ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRANT
              REQUIREMENTS OF THE ACT."

          G.  I have no present plan or intention to sell, exchange or otherwise
          dispose of any Technitrol Common Stock. I further agree to provide
          notice to both the Company and Technitrol if my plans represented in
          this paragraph G in any way change.

          H.  Technitrol agrees to use its reasonable best efforts to file all
          reports and data with the Commission necessary to permit the
          undersigned to sell Technitrol Common Stock issued pursuant to the
          Merger in conformity with Rule 145 promulgated by the Commission under
          the Act.

          It is understood and agreed that the legends set forth in paragraphs E
and F above shall be removed by delivery of substitute certificates without such
legend if the undersigned shall have delivered to Technitrol a copy of a letter 
from the staff of the Commission, or an opinion of counsel reasonably acceptable
to Technitrol and in form and substance reasonably satisfactory to Technitrol, 
to the effect that such legend is not required for purposes of the Act.

          Execution of this letter should not be considered an admission on my 
part that I am an "affiliate" of the Company as described in the first 
paragraph of this letter, or as a waiver


                                      -3-

of any rights I may have to object to any claim that I am such an affiliate on

The Board of Directors
Technitrol, Inc.
1210 Northbrook Drive
Suite 385
Trevose, PA   19053


Members of the Board:

     Technitrol, Inc. ("Technitrol") and Pulse Engineering, Inc. ("Pulse") have
entered into an Agreement and Plan of Merger (the "Agreement") dated May 23,
1995, which provides, among other things, for the merger (the "Merger") of Pulse
with and into Teco Sub Corp. ("Teco Sub"), a wholly-owned subsidiary of
Technitrol.  Pursuant to the Agreement and as a result of the Merger, each
outstanding share of common stock, par value $.01 per share, of Pulse, shall be
converted into:  (i) the right to receive .5812 shares of common stock, par
value $.125 per share, of Technitrol (the "Exchange Ratio"), subject to
adjustment if the average closing price of Technitrol common stock for the ten
trading days immediately preceding the three days preceding the filing of a
merger agreement (the "Average Closing Price") is less than $13 3/4 or greater
than $16 3/8, (ii) the right to receive $8.50 in cash, or (iii) the right to
receive a combination of Technitrol common stock and cash.  The terms and
conditions of the Merger are more fully set forth in the Agreement.

     We have acted as financial advisor to the Board of Directors of Technitrol
in connection with the Merger and will receive a fee for our services, a portion
of which is contingent upon our delivery of a written opinion to the Board of
Directors.

     In arriving at our opinion set forth below we have, among other things:

       (i) reviewed the Agreement;

           statements of Technitrol and Pulse and certain other publicly
           available information of Technitrol and Pulse;

     (iii) reviewed certain internal information, primarily financial in nature,
           concerning Technitrol and Pulse prepared by their respective
           managements;

           furnished to us by the senior management of Technitrol;

           Technitrol and Pulse concerning the operations, financial condition
           and future prospects of the combined company;

       (x) reviewed recent stock market data relating to Technitrol and Pulse;

      (xi) reviewed certain publicly available financial and stock market data
           relating to selected public companies that we considered relevant to
           our inquiry;

     (xii) analyzed certain publicly available information concerning the terms
           of selected merger and acquisition transactions that we considered
           relevant to our inquiry;

    (xiii) considered the pro forma financial effects of the Merger on
           Technitrol; and

     (xiv) conducted such other financial studies, analyses and investigations
           and considered such other information as we deemed necessary or
           appropriate.

     We are not expressing any opinion as to what the value of Technitrol common
stock actually will be when issued to Pulse shareholders pursuant to the
Agreement.

     In connection with our review, we have assumed and relied upon the accuracy
and completeness of all financial and other information supplied to us by
Technitrol and Pulse, or publicly available, and we have not independently
verified such information.  We also have relied upon the managements of
Technitrol and Pulse as to the reasonableness and achievability of the financial
projections (and the assumptions and bases therefore) provided to us and we have
assumed that such projections have been reasonably prepared on bases reflecting
the best currently available estimates and judgments of management as to the
future operating performance of Technitrol and Pulse.  We have not been
requested to make, and we

have not made, an independent appraisal or evaluation of the assets, properties,
facilities or liabilities of Technitrol or of Pulse and we have not been
furnished with any such appraisal or evaluation. Our opinion is necessarily
based on stock prices and economic and other conditions and circumstances as in
effect on, and the information made available to us as of, the date hereof.

     It is understood that this letter is directed to Technitrol's Board of
Directors and does not constitute a recommendation to any stockholder of
Technitrol as to how such stockholder should vote on the Merger. This letter is
not to be quoted or referred to, in whole or in part, in any registration
statement, prospectus or proxy statement, or in any other document used in
connection with the offering or sale of securities, nor shall this letter be
used for any other purposes, without the prior written consent of Legg Mason
Wood Walker, Incorporated, provided that this opinion may be included in its
entirety in any filing made by Technitrol with the Securities and Exchange
Commission with respect to the Merger and the transactions related thereto.

     Based upon and subject to the foregoing, we are of the opinion that, as of
the date hereof, the consideration to be paid for the Pulse common stock
pursuant to the Agreement is fair to the shareholders of Technitrol, from a
financial point of view.


                                          Very truly yours,

May 22, 1995


The Board of Directors
Pulse Engineering, Inc.
12220 World Trade Drive
San Diego, CA  92128

Gentlemen:

You have requested our opinion as to the fairness, from a financial point of
view, to the holders of the outstanding shares of Class A Voting Common Stock,
par value $0.01 per share, (the "Pulse Shares") of Pulse Engineering, Inc. (the
"Company") of the offer of 0.5812 shares of Technitrol, Inc. ("Technitrol")
Common Stock, $0.125 par value, (the "Technitrol Shares") per Pulse Share, or,
at the election of the individual holders of Pulse Shares and subject to the
limitation set forth below, $8.50 cash per Pulse Share (collectively, the
"Consideration") being offered to such holders pursuant to the terms and
conditions set forth in the Agreement and Plan of Merger By and Among
Technitrol, Inc., Technitrol Sub Corp. and Pulse Engineering, Inc. dated as of
May 23, 1995 (the "Agreement"). The Agreement, among other limitations, permits
an election by holders of Pulse Shares to receive either cash or Technitrol
Shares subject to the requirement that, of the total Pulse Shares, no less than
50%, and no more than 55%, be exchanged for Technitrol Shares, with pro rata
adjustment effected as necessary.

In arriving at our opinion, we reviewed the Agreement and held discussions with
certain senior officers, directors and other representatives and advisors of the
Company and of Technitrol concerning the business, operations and prospects of
the Company and of Technitrol. We visited certain facilities operated by the
Company and certain facilities operated by Technitrol. We examined certain
publicly available business and financial information relating to the Company
and Technitrol as well as certain financial forecasts and other data which were
provided to us by the senior managements of the Company and of Technitrol. We
reviewed the financial terms set forth in the Agreement in relation to, among
other things: current and historical market prices and trading volumes of the
Pulse Shares and the Technitrol Shares; the Company's and Technitrol's
historical and projected earnings; and the capitalization and financial
condition of the Company and of Technitrol. We also considered, to the extent
publicly available, the financial terms of certain other similar transactions
recently effected which we considered comparable to the transaction set forth in
the Agreement and analyzed certain financial, stock
<PAGE>
 
market and other publicly available information relating to the businesses of
other companies whose operations we considered comparable to those of the
Company and Technitrol. In addition to the foregoing, we conducted such other
analyses and examinations and considered such other financial, economic and
market criteria as we deemed necessary to arrive at our opinion.

In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information publicly available, including such information furnished to us or
otherwise discussed with us by management of the Company and Technitrol. With
respect to financial forecasts and other information so provided or otherwise
discussed with us, we assumed at the direction of the Board that such forecasts
and other information were reasonably prepared on bases reflecting the best
currently available estimates and judgments of the management of the Company and
of Technitrol as to the expected future financial performance of the Company and
of Technitrol. We have not made or been provided with an independent evaluation
or appraisal of the assets or liabilities (contingent or otherwise) of the
Company or of Technitrol nor have we made physical inspection of all of the
properties or assets of the Company or of Technitrol. Our opinion is necessarily
based upon financial, stock market and other conditions and circumstances
existing and disclosed to us as of the date hereof.

Oppenheimer & Co., Inc. has been engaged to render financial advisory services
to the Company in connection with the Agreement and activities leading up to the
receipt of the offer set forth in the Agreement. Oppenheimer & Co., Inc. will
receive a fee for its services which include the delivery of this opinion. In
the ordinary course of our business, we and our affiliates may actively trade
the securities of the Company for our own account or for the account of our
customers and, accordingly, may at any time hold a long or short position in
such securities. In 1986, Oppenheimer, together with management of the Company
and certain other investors, acquired the Company from its previous owner. At
that time and subsequently, Oppenheimer employees, including members of
Oppenheimer's senior management, have acquired, and in many cases still hold,
significant amounts of common stock, and warrants to purchase common stock, of
the Company. In addition, Oppenheimer employees have served on the Board from
the time of the 1986 acquisition until mid-1994. Oppenheimer co-managed the
Company's initial public offering in June 1991.

Our advisory services and the opinion expressed herein are provided solely for
the use of the Board of Directors of the Company in its evaluation of the
proposed Agreement, and our opinion may not be published or otherwise used or
referred to, in whole or in part, nor shall any public reference to Oppenheimer
& Co., Inc. be made without our prior written consent; provided that this
opinion may be included in its entirety in any filing made by the Company or
Technitrol
<PAGE>
 
with the Securities and Exchange Commission with respect to the merger
contemplated by the Agreement and the transactions related thereto.

Based upon and subject to the foregoing, our experience as investment bankers,
our work as described above and other factors we deemed relevant, we are of the
opinion that, as of the date hereof, the Consideration to be paid to the holders
of the Pulse Shares, other than Technitrol, pursuant to the Agreement is fair,
from a financial point of view, to the holders of the Pulse Shares.

Very truly yours,

OPPENHEIMER & CO., INC.

subsection (d) of this section with respect to such shares, who continuously 
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d) of this section and who has neither

pursuant to (S)228 of this title shall be entitled to an appraisal by the Court 
of Chancery of the fair value of his shares of stock under the circumstances 
described in subsections (b) and (c) of this section. As used in this section, 
the word "stockholder" means a holder of record of stock in a stock corporation 
and also a member of record of a nonstock corporation; the words "stock" and 
"share" mean and include what is ordinarily meant by those words and also 
membership or membership interest of a member of a nonstock corporation; and the

depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

series of stock of a constituent corporation in a merger or consolidation to be 
effected pursuant to (S)251, 252, 254, 257, 258, 263 or 264 of this title:

          (1) Provided, however, that no appraisal rights under this section
          shall be available for the shares of any class or series of stock,
          which stock, or depository receipts in respect thereof, at the record

          and to vote at the meeting of stockholders to act upon the agreement
          of merger or consolidation, were either (i) listed on a national

          holders; and further provided that no appraisal rights shall be
          available for any share of stock of the constituent corporation
          surviving a merger if the merger did not require for its approval the
          vote of the holders of the surviving corporation as provided in
          subsection (f) of (S)251 of this title.

<PAGE>
 
          (2)  Notwithstanding paragraph (1) of this subsection, appraisal 
          rights under this section shall be available for the shares of any 
          class or series of stock of a constituent corporation if the holders 
          thereof are required by the terms of an agreement of merger or

          this title to accept for such stock anything except:

          from such merger or consolidation, or depository receipts in respect 
          thereof;

               b.  Shares of stock of any other corporation, or depository 
          receipts in respect thereof, which shares of stock or depository 
          receipts at the effective date of the merger or consolidation will be 
          either listed on a national securities exchange or designated as a 
          national market system security on an interdealer quotation system by 
          the National Association of Securities Dealers, Inc. or held of record
          by more than 2,000 holders;

               c.  Cash in lieu of fractional shares or fractional depository
          receipts described in the foregoing subparagraphs a. and b. of this 
          paragraph; or 

               d.  Any combination of the shares of stock, depository receipts 
          and cash in lieu of fractional shares or fractional depository 
          receipts described in the foregoing subparagraphs a., b. and c. of 
          this paragraph.

          (3)  In the event all of the stock of a subsidiary Delaware
          corporation party to a merger effected under (S)253 of this title is
          not owned by the parent or corporation immediately prior to the
          merger, appraisal rights shall be available for the shares of the
          subsidiary Delaware corporation.

     (c)  Any corporation may provide in its certificate of incorporation that 
appraisal rights under this section shall be available for the shares of any 
class or series of its stock as a result of an amendment to its certificate of 
incorporation, any merger or consolidation in which the corporation is a 
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision, 
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d)  Appraisal rights shall be perfected as follows:


<PAGE>
 
          (1)  If a proposed merger or consolidation for which appraisal rights
          are provided under this section is to be submitted for approval at a
          meeting of stockholders, the corporation, not less than 20 days prior
          to the meeting, shall notify each of its stockholders who was such on
          the record date for such meeting with respect to shares for which
          appraisal rights are available pursuant to subsection (b) or (c)
          hereof that appraisal rights are available for any or all of the
          shares of the constituent corporations, and shall include in such
          notice a copy of this section. Each stockholder electing to demand the
          appraisal of his shares shall deliver to the corporation, before the
          taking of the vote on the merger or consolidation, a written demand
          for appraisal of his shares. Such demand will be sufficient if it
          reasonably informs the corporation of the identity of the stockholder
          and that the stockholder intends thereby to demand the appraisal of
          his shares. A proxy or vote against the merger or consolidation shall
          not constitute such a demand. A stockholder electing to take such
          action must do so by a separate written demand as herein provided.
          Within 10 days after the effective date of such merger or
          consolidation, the surviving or resulting corporation shall notify
          each stockholder of each constituent corporation who has complied with
          this subsection and has not voted in favor of or consented to the
          merger or consolidation of the date that the merger or consolidation
          has become effective; or

          (2)  If the merger or consolidation was approved pursuant to (S)228 or
          253 of this title, the surviving or resulting corporation, either
          before the effective date of the merger or consolidation or within 10
          days thereafter, shall notify each of the stockholders entitled to
          appraisal rights of the effective date of the merger or consolidation 
          and that appraisal rights are available for any or all of the shares 
          of the constituent corporation, and shall include in such notice a 
          copy of this section. The notice shall be sent by certified or 
          registered mail, return receipt requested, addressed to the 
          stockholder at his address as it appears on the records of the 
          corporation. Any stockholder entitled to appraisal rights may, within 
          20 days after the date of mailing of the notice, demand in writing 
          from the surviving or resulting corporation the appraisal of his 
          shares. Such demand will be sufficient if it reasonably informs the 
          corporation of the identity of the stockholder and that the 
          stockholder intends thereby to demand the appraisal of his shares.
<PAGE>
 
     (e)  Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after the expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.

     (f)  Upon the filing of any such petition by a stockholder, service of a 
copy thereof shall be made upon the surviving or resulting corporation, which 
shall within 20 days after such service file in the office of the Register in 
Chancery in which the petition was filed a duly verified list containing the 
names and addresses of all stockholders who have demanded payment for their 
shares and with whom agreements as to the value of their shares have not been 
reached by the surviving or resulting corporation. If the petition shall be 
filed by the surviving or resulting corporation, the petition shall be 
accompanied by such a duly verified list. The Register in Chancery, if so 
ordered by the Court, shall give notice of the time and place fixed for the 
hearing of such petition by registered or certified mail to the surviving or 
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at 
least 1 week before the day of the hearing in a newspaper of general 
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication 
shall be approved by the Court, and the costs thereof shall be borne by the 
surviving or resulting corporation.

     (g)  At the hearing on such petition, the Court shall determine the 
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an 
appraisal for their shares and who hold stock represented by certificates to 
submit 






<PAGE>
 
their certificates of stock to the Register in Chancery for notation thereon of 
the pendency of the appraisal proceedings; and if any stockholder fails to 
comply with such direction, the Court may dismiss the proceedings as to such 
stockholder.

     (h)  After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or 
consolidation, together with a fair rate of interest, if any, to be paid upon 
the amount determined to be the fair value. In determining such fair value, the 
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of 
interest which the surviving or resulting corporation would have had to pay to 
borrow money during the pendency of the proceeding. Upon application by the 
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the court may, in its discretion, permit discovery 
or other pretrial proceedings and may proceed to trial upon the appraisal prior 
to the final determination of the stockholder entitled to an appraisal. Any 
stockholder whose name appears on the list filed by the surviving or resulting 
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may 
participate fully in all proceedings until it is finally determined that he is 
not entitled to appraisal rights under this section.

     (i)  The Court shall direct the payment of the fair value of the shares, 
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court 
may direct. Payment shall be so made to each such stockholder, in the case of 
holders of uncertificated stock forthwith, and the case of holders of shares 
represented by certificates upon the surrender to the corporation of the 
certificates representing such stock. The Court's decree may be enforced as 
other decrees in the Court of Chancery may be enforced, whether such surviving 
or resulting corporation be a corporation of this State or of any state.

     (j)  The costs of the proceedings may be determined by the Court and taxed 
upon the parties as the Court deems equitable in the circumstances. Upon 
application of a stockholder, the Court may order all or a portion of the 
expenses incurred by any stockholder in connection with the appraisal 
proceeding, including, without limitation, reasonable attorney's fees and the 
fees and expenses of experts, to be charged pro rata against the value of all 
the shares entitled to an appraisal.

     (k)  From and after the effective date of the merger or consolidation, no 
stockholder who had demanded his appraisal 



<PAGE>
 

rights as provided in subsection (d) of this section shall be entitled to vote 
such stock for any purpose or to receive payment of dividends or other 
distributions on the stock (except dividends or other distributions payable to 
stockholders of record at a date which is prior to the effective date of the 
merger or consolidation); provided, however, that if no petition for an 
appraisal shall be filed within the time provided in subsection (e) of this 
section, or if such stockholder shall deliver to the surviving or resulting 
corporation a written withdrawal of his demand for an appraisal and an 
acceptance of the merger or consolidation, either within 60 days after the 
effective date of the merger or consolidation as provided in subsection (e) of 
this section or thereafter with the written approval of the corporation, then 
the right of such stockholder to an appraisal shall cease. Notwithstanding the 
foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed 
as to any stockholder without the approval of the Court, and such approval may 
be conditioned upon such terms as the Court deems just.

     (l)  The shares of the surviving or resulting corporation to which the 
shares of such objecting stockholders would have been converted had they 
assented to the merger or consolidation shall have the status of authorized and 
unissued shares of the surviving or resulting corporation.

                                    PART II
 
                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Article VII of the Registrant's Bylaws provides for the indemnification of
officers, directors and third parties acting on behalf of the corporation if
such person acted in good faith and in a manner reasonably believed to be in
and not opposed to the best interest of the corporation, and, with respect to
any criminal action or proceeding the indemnified party had no reason to
believe his conduct was unlawful.
 
  Section 518 of the Pennsylvania Business Corporation Law permits a
corporation to include in its bylaws, and in agreements between the
corporation and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.

ITEM 22. UNDERTAKINGS
 
  (1) The undersigned Registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c),
the undersigned Registrant undertakes that such reoffering prospectus will
contain the information called for by the applicable registration form with
respect to reofferings by persons who may be deemed underwriters, in addition
to the information called for by the other Items of the applicable form.
 
  (2) The Registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.
 
                                     II-1
<PAGE>
 
  (3) Insofar as the indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.
 
  (4) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through
the date of responding to the request.
 
  (5) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

                    Re:  REGISTRATION STATEMENT ON FORM S-4
                         ----------------------------------

Ladies and Gentlemen:

               We have acted as counsel to Technitrol, Inc. (the "Company") in
the preparation and filing with the Securities and Exchange Commission of a
registration statement on Form S-4 (the "Registration Statement"), for the
purpose of registering under the Securities Act of 1933, as amended, up to
1,809,077 shares of the Company's Common Stock, par value $.125 per share (the
"Common Stock"). Each capitalized term used but not defined in this opinion
letter has the meaning ascribed to it in the Registration Statement.

               For the purpose of rendering the opinions contained herein, we
have examined such matters of law as we deem necessary or appropriate and have
examined and relied (without independent investigation) on only the following
documents, records and certificates:

               (1)  a subsistence certificate with respect to the Company issued
                    by the Secretary of State of the Commonwealth of
                    Pennsylvania on August 10, 1995;

               (2)  the Articles of Incorporation, as amended, of the Company,
                    certified by the Secretary of the Company;

               (3)  the By-laws of the Company, certified by the Secretary of
                    the Company;

               (4)  certain minutes of proceedings of the Company's Board of
                    Directors, certified by the Secretary of the Company,
                    relating to the offer and sale

                    by the Company of the Common Stock offered pursuant to the
                    Prospectus; and

               (5)  the Registration Statement.

               In rendering this opinion, we have assumed and relied upon,
without independent investigation, other than the inquiry referred to above, (i)
the authenticity, completeness, truth and due authorization, execution and
delivery of all documents submitted to us as originals, (ii) the genuineness of
all signatures on all documents submitted to us as originals, and (iii) the
conformity to the originals of all documents submitted to us as certified or
photostatic copies.

               The laws covered by the opinions expressed herein are limited to
the Federal statutes, judicial decisions and rules and regulations of the
governmental agencies of the United States and the statutes, judicial and
administrative decisions and rules and regulations of the governmental agencies
of the Commonwealth of Pennsylvania.

               This opinion letter is given only with respect to laws and
regulations presently in effect. We assume no obligation to advise you of any
changes in law or regulation which may hereafter occur, whether the same are
retroactively or prospectively applied, or to update or supplement this letter
in any fashion to reflect any facts or circumstances which hereafter come to our
attention.

               Based upon the foregoing, it is our opinion that, upon completion
of the merger proceedings being taken or contemplated by us as your counsel
prior to the issuance of the Common Stock, and upon completion of the
proceedings being taken in order to permit such transactions to be carried out
in accordance with the securities laws of the various states where required, the
Common Stock, when issued in the manner described in the Registration Statement,
will be legally and validly issued, fully paid and non-assessable.

               We hereby consent to (i) the filing of this opinion letter as an
exhibit to the Registration Statement and (ii) the use of our name wherever

          Re:  AGREEMENT AND PLAN OF MERGER DATED AS OF MAY 23, 1995 (THE
               "AGREEMENT"), BY AND AMONG TECHNITROL, INC. ("TECHNITROL"), TECO
               SUB, INC. ("TECO SUB") AND PULSE ENGINEERING, INC. ("PULSE")
                                      ------------------------------------------

Gentlemen:

          You have requested our opinion as to certain federal income tax
consequences of the merger, pursuant to the Agreement, of Pulse into Teco Sub in
which each share of Pulse Common Stock will be converted into and become the
right to receive shares of Technitrol Common Stock and/or cash (the "Merger").
All terms used herein unless otherwise defined are used as defined in the
Agreement.

          In rendering our opinion with respect to the Merger, we reviewed and
relied upon (a) the Agreement, (b) the Joint Proxy Statement and Prospectus of
Technitrol and Pulse, dated August ___, 1995; (c) certain representations
concerning the Merger made to us by Technitrol and Pulse in a letter August ___,
1995, (the "Representation Letter"); and (d) all other documents, financial and
other reports and corporate minutes which we deemed relevant or appropriate.
<PAGE>
Technitrol, Inc.

          Our review of items (a) through (d) of the preceding paragraph has
been without independent investigation. We have also relied upon the truth,
authenticity, accuracy and completeness of all documents, certifications and
instruments examined and the statements, covenants, representations and
warranties contained therein, the genuineness of all documents submitted to us
as originals, the conformity of the originals of all documents submitted to us
as certified or photostatic copies and the due execution and delivery of all
documents where execution and delivery are pre-requisites to the effectiveness
thereof.

          Based on the foregoing and provided the Merger is carried out in
accordance with the applicable laws of the Commonwealth of Pennsylvania, the
Agreement and the Representation Letter, it is our opinion that:

          1.   The Merger will constitute a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code").

          2.   Technitrol, Teco Sub and Pulse will each be "a party to a
reorganization" within the meaning of Section 368(b) of the Code.

          3.   No gain or loss will be recognized by Pulse upon the transfer of
its assets to Teco Sub in exchange for the distribution to holders of Pulse
Common Stock of Technitrol Common Stock (including fractional share interests)
and/or cash, and the assumption by Teco Sub of the liabilities of Pulse, as
provided in Sections 361 and 357(a) of the Code.

          4.   No gain or loss will be recognized by either Technitrol or Teco
Sub upon the receipt by Teco Sub of the assets of Pulse in exchange for
Technitrol Common Stock (including fractional share interests), cash, and the
assumption of Pulse's liabilities by Teco Sub.  See Rev. Rul. 57-278, 1957-1
Cum. Bull. 124.

          5.   The basis of the Pulse assets in the hands of Teco Sub will be
the same as the basis of such assets in the hands of Pulse immediately prior to
the Merger, as provided in Section 362(b) of the Code.

          6.   The holding period for the assets of Pulse to be received by Teco
Sub will include the period during which the assets were held by Pulse as
provided in Section 1223(2) of the Code.
<PAGE>
Technitrol, Inc.
August 15, 1995
Page 3
 
          7.   No gain or loss will be recognized by Pulse shareholders who
receive solely Technitrol Common Stock in exchange for their Pulse Common Stock
(except those shareholders who receive cash for fractional shares), as provided
in Section 354(a)(1) of the Code.

          8.   The basis of Technitrol Common Stock received by Pulse
shareholders who received solely Technitrol Common Stock (including a fractional
share interest) will be the same as the basis of the Pulse Common Stock
surrendered in exchange therefor as provided in Section 358(a)(1) of the Code.

          9.   The holding period of Technitrol Common Stock received by Pulse
shareholders (including a fractional share interest) will include the holding
period of the Pulse Common Stock surrendered in exchange therefor, provided that
the Pulse Common Stock is held as a capital asset on the date of the exchange,
as provided in Section 1223(1) of the Code.

          10.  The payment of cash in lieu of fractional share interests will be
treated as if the fractional share interests were distributed as a part of the
Merger and then redeemed by Technitrol.  Such cash payments will be treated as
having been received as distributions in full payment in exchange for the
fractional share interests redeemed and gain or loss will be recognized as
provided in Section 302(a) of the Code.

          11.  Holders of Pulse Common Stock who receive both Technitrol Common
Stock and cash in exchange for their Pulse Common Stock and who realize a gain
on the exchange will recognize such gain, to the extent of the cash received,
pursuant to Section 356(a)(1) of the Code.  Such recognized gain may be treated
as a dividend pursuant to Section 356(a)(2) of the Code.  The determination of
whether a recognized gain is treated as a dividend will be determined under the
principles of COMMISSIONER V. CLARK, 489 U.S. 726 (1989).  No loss will be
recognized by a holder of Pulse Common Stock pursuant to Section 356(a) of the
Code.  Holders of Pulse Common Stock who receive both Technitrol Common Stock
and cash will adjust their bases in the Technitrol Common Stock to account for
the cash received, any amount recognized as a gain or a dividend, and any loss
realized, pursuant to Section 358.

          12.  Holders of Pulse Common Stock who receive solely cash in exchange
for their Pulse Common Stock will recognize gain or loss measured by the amount
of cash received therefor and the basis of their Pulse Common Stock.  If such
transaction results in an exchange under Section 302(a) of the Code, such gain
will be long or short term capital gain depending on whether their
<PAGE>

Page 4
 
holding period for their Pulse Common Stock was more than one year or one year
or less, provided the Pulse Common Stock is held as a capital asset on the date
of the exchange, as provided in Sections 302(a) and 1222 of the Code.

          13.  Pursuant to Section 381(a) of the Code and Treasury Regulations
Section 1.381(a)-1, Teco Sub will succeed to and take into account the items
(i.e., tax attributes) of Pulse described in Section 381(c) of the Code.  These
items will be taken into account by Teco Sub subject to the conditions and
limitations specified in Sections 381, 382, 383 and 384 of the Code and the
Treasury Regulations thereunder.

          14.  As provided in Section 381(c)(2) of the Code and Treasury
Regulations Section 1.381(c)(2)-1, Teco Sub will succeed and take into account
the earnings and profits, or deficit in earnings and profits, of Constitution as
of the date of the transfer.  Any deficit in earnings and profits of Pulse or
Teco Sub may be used only to offset earnings and profits accumulated after the
date of the transfer.  Any earnings and profits of Pulse or Teco Sub accumulated
before the date of the transfer will be used to offset any deficit in earnings
and profits incurred after the transfer.

          Our opinions are based upon the Code, as amended, the applicable
Treasury Regulations promulgated thereunder, the present positions of the
Internal Revenue Service as set forth in published revenue rulings and revenue
procedures and existing judicial decisions, all of which are subject to change
either prospectively or retroactively in such a fashion as to have a Material
Adverse Effect upon the conclusions reached in our opinions as aforesaid. In
rendering our opinion based on the foregoing, you should be aware that our
opinion is not binding upon the Internal Revenue Service or any court and there
is no assurance that the Internal Revenue Service would not successfully assert
a contrary opinion upon an audit of the relevant tax return of any party to the
Merger or shareholder thereof, or otherwise.

          Our opinions are conditioned upon the performance by Technitrol, Teco
Sub and Pulse of their undertakings in the

Representation Letter.  These opinions are being rendered to you and may be
relied upon only by you and Teco Sub shareholders.

<PAGE>
 
  IN MAKING A STOCK ELECTION OR A CASH ELECTION, PULSE STOCKHOLDERS SHOULD
CONSIDER THAT BECAUSE THE STOCK CONSIDERATION HAS BEEN FIXED AT 0.5812
TECHNITROL SHARES (SUBJECT TO ADJUSTMENT) FOR EACH SHARE OF PULSE COMMON
STOCK, AND BECAUSE THE MARKET PRICE OF TECHNITROL SHARES IS SUBJECT TO
FLUCTUATION, THE MARKET VALUE OF THE TECHNITROL SHARES THAT HOLDERS OF PULSE
COMMON STOCK MAY RECEIVE IN THE MERGER FOR EACH SHARE OF PULSE COMMON STOCK

STOCK MAY RECEIVE IN THE MERGER MAY INCREASE OR DECREASE FOLLOWING THE
EFFECTIVE TIME (AS DEFINED IN INSTRUCTION A).

certificates are received by the Exchange Agent by the Guaranteed Delivery
Deadline), you will be deemed to have made a Non-Election.
 
  The undersigned hereby certifies: that this Election covers all of the
shares of Pulse Common Stock registered in the name of the undersigned and
either (i) beneficially owned by the undersigned, or (ii) owned by the
undersigned in a representative or fiduciary capacity for a particular
beneficial owner or for one or more beneficial owners.

  This Election is subject to the terms and conditions set forth in the Merger
Agreement and the Proxy Statement-Prospectus, furnished to stockholders of
Pulse in connection with the Merger, all of which are incorporated herein by
reference. Receipt of the Proxy Statement-Prospectus, including the Merger
Agreement attached as Annex A thereto, is hereby acknowledged. Copies of the
Proxy Statement-Prospectus are available from the Exchange Agent upon request
(see Instruction G(10)).
 
  It is understood that because pursuant to the Merger Agreement the number of
shares of Pulse Common Stock to be converted into the right to receive
Technitrol Shares in the Merger and the number of shares of Pulse Common Stock
to be converted into the right to receive cash in the Merger are subject to
limitations, no assurance can be given that an Election by any given
stockholder, including this Election by the undersigned, can be accommodated.
Rather, the Election by each holder of Pulse Common Stock, including this
Election by the undersigned, will be subject to the results of the election
and allocation procedures set forth in the Merger Agreement and described in
the Proxy Statement-Prospectus under the caption "TERMS OF THE MERGER--
Conversion of Shares of Pulse Common Stock; Election" (the "Election and
Allocation Procedures").

DELIVERY, AS DESCRIBED BELOW), NO LATER THAN 5:00 P.M., EASTERN DAYLIGHT TIME,
ON SEPTEMBER 28, 1995, IN ORDER TO ASSURE THAT THEIR FORM OF ELECTION WILL BE

thereby guaranteed, are in fact delivered to the Exchange Agent no later than
5:00 p.m., Eastern Daylight Time, on the fourth business day after the date of
execution of such Guaranty of Delivery (the "Guaranteed Delivery Deadline")).
 
  IF THE EXCHANGE AGENT HAS NOT RECEIVED YOUR PROPERLY COMPLETED FORM OF
ELECTION, ACCOMPANIED BY YOUR STOCK CERTIFICATES, BY THE ELECTION DEADLINE
(UNLESS BOX E (GUARANTY OF DELIVERY) HAS BEEN PROPERLY COMPLETED AND SUCH
CERTIFICATES ARE RECEIVED BY THE EXCHANGE AGENT BY THE GUARANTEED DELIVERY
DEADLINE), YOU WILL BE DEEMED TO HAVE MADE A NON-ELECTION.
 
  For instructions regarding changes or revocations of Elections and the time
in which such changes or revocations can be made, see Instructions F(1) and
F(2) below.
 
B. ELECTIONS
 
  This Form of Election provides for your Election, subject to the Election
and Allocation Procedures and the other items and conditions set forth
hereunder and in the documents incorporated herein by reference, upon
consummation of the Merger to have each of the shares of Pulse Common Stock
covered by this Form of Election converted into the right:
 
  --to receive $8.50 in cash without interest (a "Cash Election"); or
 
  --to receive 0.5812 Technitrol Shares (subject to adjustment based on the
    average closing price of Technitrol Common Stock for a specified two-week
    period prior to the Merger as set forth in the Merger Agreement and as
    more fully described in the Proxy Statement--Prospectus) (a "Stock
    Election"); or
 
  --to indicate no preference with regard to a Cash Election or Stock
    Election (a "Non-Election").

<PAGE>
 
  A HOLDER OF SHARES OF PULSE COMMON STOCK THAT DOES NOT SUBMIT AN EFFECTIVE
FORM OF ELECTION PRIOR TO THE ELECTION DEADLINE WILL BE DEEMED TO HAVE MADE A
NON-ELECTION.
 
  IN MAKING A STOCK ELECTION OR A CASH ELECTION, PULSE STOCKHOLDERS SHOULD
CONSIDER THAT BECAUSE THE STOCK CONSIDERATION HAS BEEN FIXED AT 0.5812
TECHNITROL SHARES (SUBJECT TO ADJUSTMENT) FOR EACH SHARE OF PULSE COMMON
STOCK, AND BECAUSE THE MARKET PRICE OF TECHNITROL SHARES IS SUBJECT TO
FLUCTUATION, THE MARKET VALUE OF THE TECHNITROL SHARES THAT HOLDERS OF PULSE
COMMON STOCK MAY RECEIVE IN THE MERGER FOR EACH SHARE OF PULSE COMMON STOCK
MAY BE LESS THAN, EQUAL TO, OR GREATER THAN THE CASH CONSIDERATION OF $8.50.
IN ADDITION, BECAUSE OF SUCH FLUCTUATIONS IN THE MARKET VALUE OF THE
TECHNITROL SHARES, THE MARKET VALUE OF THE TECHNITROL SHARES THAT HOLDERS OF
PULSE COMMON STOCK MAY RECEIVE IN THE MERGER MAY INCREASE OR DECREASE
FOLLOWING THE EFFECTIVE TIME.
 
  You should understand that your Election is subject to certain terms and
conditions that are set forth in the Merger Agreement and described in the
Proxy Statement-Prospectus. The Merger Agreement is included as Annex A to the
Proxy Statement-Prospectus. Copies of the Proxy Statement-Prospectus may be
requested from the Exchange Agent at the address or phone number set forth in
Instruction G(10). The delivery of this Form of Election to the Exchange Agent
constitutes acknowledgement of the receipt of the Proxy Statement-Prospectus.
EACH HOLDER OF PULSE COMMON STOCK IS STRONGLY ENCOURAGED TO READ THE PROXY
STATEMENT-PROSPECTUS IN ITS ENTIRETY AND TO DISCUSS THE CONTENTS THEREOF, THE
MERGER AND THIS FORM OF ELECTION WITH HIS OR HER PERSONAL FINANCIAL AND TAX
ADVISORS PRIOR TO DECIDING WHAT ELECTION TO MAKE. THE TAX CONSEQUENCES TO A
HOLDER OF PULSE COMMON STOCK WILL VARY DEPENDING UPON A NUMBER OF FACTORS,
INCLUDING WHETHER SUCH HOLDER RECEIVES TECHNITROL SHARES, CASH OR A
COMBINATION THEREOF. FOR CERTAIN INFORMATION REGARDING THE FEDERAL INCOME TAX
CONSEQUENCES OF AN ELECTION, SEE "THE MERGER AND RELATED TRANSACTIONS--CERTAIN
FEDERAL INCOME TAX CONSIDERATIONS" IN THE PROXY STATEMENT-PROSPECTUS.
 
C. CASH ELECTION
 
  If you elect, subject to the Election and Allocation Procedures and the
other terms and conditions set forth in this Form of Election, including the
documents incorporated herein by reference, to receive cash for all of the
shares of Pulse Common Stock covered by this Form of Election, you should
check the "Cash Election" box on the first page of this Form of Election.
 
D. STOCK ELECTION
 
  If you elect, subject to the Election and Allocation Procedures and the
other terms and conditions set forth in this Form of Election, including the
documents incorporated herein by reference, to receive Technitrol Shares for
all of the shares of Pulse Common Stock covered by this Form of Election, you
should check the "Stock Election" box on the first page of this Form of
Election.
 
  Technitrol will not issue any fractional Technitrol Shares in connection
with the Merger; a holder of Pulse Common Stock will instead receive cash in
an amount equal to (i) the average closing price of Technitrol Common Stock on
the American Stock Exchange as reported in The Wall Street Journal for the ten
trading days immediately preceding the three business days preceding the
Effective Time multiplied by (ii) the fractional share amount such
stockholders would otherwise be entitled (after taking into account all shares
of Pulse Common Stock held by such holder), without interest, rounded to the
nearest cent.
 
E. NON-ELECTION
 
  If you have no preference for either cash or Technitrol Shares, you should
check the "Non-Election" box on the first page of this Form of Election.
 
                                       7
<PAGE>
 
  If you have failed to make an effective Cash Election, Stock Election, or
Non-Election for all of the shares of Pulse Common Stock required to be
covered by this Form of Election, or if your Election is deemed by the
Exchange Agent or Technitrol to be defective in any way, or if your Form of
Election is not accompanied by your certificates (unless Box E (Guaranty of
Delivery) has been properly completed and such certificates are received by
the Exchange Agent by the Guaranteed Delivery Deadline), you will be deemed to
have made a Non-Election for all of such shares.
 
F. SPECIAL CONDITIONS
 
  (1) Change of Election. An effective Election may be changed by the person
or persons making such Election by a written notice signed and dated by such
person or persons received by the Exchange Agent prior to the Election
Deadline, identifying the name of the registered holder of the Pulse Common
Stock subject to such Election and the serial numbers shown on the
certificates representing such Pulse Common Stock, accompanied by a properly
completed, revised Form of Election.
 
  (2) Revocation of Election. An election may be revoked by the person or
persons making such election by a written notice signed and dated by such
person or persons and received by the Exchange Agent prior to the Election
Deadline, identifying the name of the registered holder of the Pulse Common
Stock subject to such Election and the serial numbers shown on the
certificates representing such Pulse Common Stock. Any person or persons who
have effectively revoked an Election may, by a signed and dated written notice
to the Exchange Agent, request the return of the stock certificates submitted
to the Exchange Agent and such certificates will be returned to such person or
persons (at the stockholder's risk) within five business days of receipt of
such request.
 
  (3) Nullification of Election. All Forms of Election will be void and of no
effect if the Merger is not consummated, and certificates submitted therewith
shall be promptly returned to the persons submitting the same.
 
  (4) Elections Subject to Allocation. All Elections are subject to the
Election and Allocation Procedures set forth in the Merger Agreement and
described in the Proxy Statement-Prospectus under the caption "TERMS OF THE
MERGER--Conversion of Shares of Pulse Common Stock; Election" and to the other

documents incorporated herein by reference.
 
  (5) Shares Held by Nominees, Trustees or other Representatives. Holders of
record of shares of Pulse Common Stock who hold such shares as nominees,
trustees or in other representative or fiduciary capacities (a
"Representative") may submit one or more Forms of Election covering the
aggregate number of shares of Pulse Common Stock held by such Representative
for the beneficial owners for whom the Representative is making an Election or
a Non-Election; provided, that such Representative certifies that each such
Form of Election covers all the shares of Pulse Common Stock held by such
Representative for a particular beneficial owner. Any Representative who makes
an Election or a Non-Election may be required to provide the Exchange Agent
with such documents and/or additional certifications, if requested, in order
to satisfy the Exchange Agent that such Representative holds such shares of
Pulse Common Stock for a particular beneficial owner of such shares. If any
shares held by a Representative are not covered by an effective Form of
Election, they will be deemed to be covered by a Non-Election.

<PAGE>
 
STOCK CERTIFICATES WILL BE DEEMED EFFECTIVE AND RISK OF LOSS WITH RESPECT TO
SUCH CERTIFICATES SHALL PASS ONLY WHEN SUCH CERTIFICATES ARE ACTUALLY RECEIVED
BY THE EXCHANGE AGENT.
 
  (2) Signatures. Except as otherwise permitted below, you must sign this Form
of Election exactly the way your name appears on the face of your
certificates. If the shares are owned by two or more persons, each must sign
exactly as his or her name appears on the face of the certificates. If shares
of Pulse Common Stock have been assigned by the registered owner, this Form of
Election should be signed in exactly the same way as the name of the assignee
appearing on the certificates or transfer documents. See Instructions G(5)(a)
and G(5)(b).
 
  (3) Notice of Defects; Resolution of Disputes. None of Pulse, Technitrol and
the Exchange Agent will be under any obligation to notify you or anyone else
that the Exchange Agent has not received a properly completed Form of Election
or that any Form of Election submitted is defective in any way.
 
  Any and all disputes with respect to Forms of Election or to Elections made
in respect of Technitrol Common Stock (including but not limited to matters
relating to the Election Deadline, time limits, defects or irregularities in
the surrender of any stock certificate, effectiveness of any Elections and
computations of allocations) will be resolved by Technitrol and its decision
will be conclusive and binding on all concerned. Technitrol may delegate this
function to the Exchange Agent in whole or in part. Technitrol or the Exchange
Agent shall have the absolute right in its sole discretion to reject any and
all Forms of Election and surrenders of stock certificates which are deemed by
either of them to be not in proper form or to waive any immaterial
irregularities in any Form of Election or in the surrender of any stock
certificate. Surrenders of stock certificates will not be deemed to have been
made until all defects or irregularities that have not been waived have been
cured.
 
  (4) Issuance of Payment Check(s) and New Certificate in Same Name. If the
certificate representing Technitrol Shares and/or the Payment Check(s) are to
be issued in the name of the registered holder(s) as inscribed on the
surrendered certificate(s), the surrendered certificate(s) need not be
endorsed and no guarantee of the signature on the Form of Election is
required. For corrections in name and change in name not involving changes in
ownership, see Instruction G(5)(c).
 
  (5) Issuance of Payment Check(s) and New Certificate in Different Name. If
the certificate representing Technitrol Shares and/or the Payment Check(s) are
to be issued in the name of someone other than the registered holder(s) of the
surrendered certificate(s), you must follow the guidelines below. Note that in
each circumstance listed below, stockholder(s) must have signature(s)
guaranteed in Box C and complete Box F.
 
    (a) Endorsement and Guarantee. The certificate(s) surrendered must be
  properly endorsed (or accompanied by appropriate stock powers properly
  executed) by the registered holder(s) of such certificate(s) to the person
  who is to receive the Technitrol Shares and/or the Payment Check(s). The
  signature(s) of the registered holder(s) on the endorsement or stock powers
  must correspond with the name(s) written upon the face of the
  certificate(s) in every particular and must be medallion guaranteed by an
  eligible guarantor institution as defined below.
 
             DEFINITION OF ELIGIBLE SIGNATURE GUARANTOR INSTITUTION
 
      An eligible guarantor institution for purposes of signature guarantee
    in Box C means a member/participant in a medallion program approved by
    the Securities Transfer Association, Inc.
 
    (b) Transferee's Signature. The Form of Election must be signed by the
  transferee or assignee or his or her agent, and should not be signed by the
  transferor or assignor. See Box B entitled "Sign Here." The signature of
  such transferee or assignee must be medallion guaranteed by an eligible
  guarantor institution as provided in Instruction G(5)(a).
 
    (c) Correction of or Change in Name. For a correction of name or for a
  change in name which does not involve a change in ownership, proceed as
  follows: For a change in name by marriage, etc., the Form of
 
                                       9
<PAGE>
 
  Election should be signed, e.g., "Mary Doe, now by marriage Mary Jones."
  For a correction in name, the Form of Election should be signed, e.g.,
  "James E. Brown, incorrectly inscribed as J.E. Brown." The signature in
  each case should be guaranteed in the manner described in Instruction
  G(5)(a) above and Box F should be completed.
 
    You should consult your own tax advisor as to any possible tax
  consequences resulting from the issuance of the Technitrol Shares
  certificate and/or Payment Check(s) in a name different from that of the
  registered holder(s) of the surrendered certificate(s).
 
  (6) Supporting Evidence. In case any Form of Election, certificate
endorsement or stock power is executed by an agent, attorney, administrator,
executor, guardian, trustee or any person in any other fiduciary or
representative capacity, or by an officer of a corporation on behalf of the
corporation, there must be submitted (with the Form of Election, surrendered
certificate(s), and/or stock powers) documentary evidence of appointment and
authority to act in such capacity (including court orders and corporate
resolutions when necessary), as well as evidence of the authority of the
person making such execution to assign, sell or transfer the certificate(s).
Such documentary evidence of authority must be in form satisfactory to the
Exchange Agent.
 
  (7) Special Instructions for Delivery by the Exchange Agent. The certificate
representing Technitrol Shares and/or the Payment Check(s) will be mailed to
the address of the registered holder(s) as indicated under Box A entitled
"Certificate Information," unless instructions to the contrary are given in
Box G entitled "Special Mailing Instructions."
 
  (8) Lost Certificates. If you are not able to locate your certificates
representing Pulse Common Stock, you should contact First Interstate Bank of
California, Pulse's transfer agent, at Corporate Trust Department, 707
Wilshire Boulevard, W11-2, Los Angeles, California 90017 or at (213) 614-2362.
In such event, First Interstate Bank will forward additional documentation
which the shareholder must complete in order to effectively surrender such
lost or destroyed certificate(s). There may be a fee to replace lost
certificates.
 
  (9) Federal Income Tax Withholding. Under Federal income tax law, the
Exchange Agent is required to file a report with the Internal Revenue Service
disclosing any payments of cash being made to each holder of certificates
formerly representing shares of Pulse Common Stock pursuant to the Merger
Agreement. In order to avoid "backup withholding" of Federal income tax on any
cash received upon the surrender of certificate(s), a holder thereof must,
unless an exemption applies, provide the Exchange Agent with his or her
correct taxpayer identification number ("TIN") on Substitute Form W-9, which
is part of this Form of Election (Box D), and certify, under penalties of
perjury, that such number is correct and that such holder is not otherwise
subject to backup withholding. If the correct TIN and certifications are not
provided, a $50 penalty may be imposed by the Internal Revenue Service and
payments made for surrender of certificate(s) may be subject to backup
withholding of 31 percent. In addition, if a holder makes a false statement
that results in no imposition of backup withholding, and there was no
reasonable basis for making such a statement, a $500 penalty may also be
imposed by the Internal Revenue Service.
 
  Backup withholding is not an additional Federal income tax. Rather, the
Federal income tax liability of a person subject to backup withholding will be
reduced by the amount of such tax withheld. If backup withholding results in
an overpayment of income taxes, a refund may be obtained from the Internal
Revenue Service.
 
  The TIN that must be provided on the Substitute Form W-9 is that of the
registered holder(s) of the certificate(s) at the Effective Time. The TIN for
an individual is his or her social security number. The box in Part II of the
Substitute Form W-9 may be checked if the person surrendering the certificates
has not been issued a TIN and has applied for a TIN or intends to apply for a
TIN in the near future. If the box in Part II has been checked, the person
surrendering the certificate(s) must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part II is checked (and the Certificate of
Awaiting Taxpayer Identification Number is completed), the Exchange Agent will
withhold 31 percent on all cash payments with respect to surrendered
certificate(s) made prior to the time it is provided with a properly certified
TIN.
 
                                      10
<PAGE>
 
  Exempt persons (including, among others, corporations) are not subject to
backup withholding. A foreign individual may qualify as an exempt person by
submitting Form W-8 or a substitute Form W-8, signed under penalties of
perjury, certifying to such person's exempt status. A form of such statement
can be obtained from the Exchange Agent. A certificate holder should consult
his or her tax advisor as to such holder's qualification for an exemption from
backup withholding and the procedure for obtaining such exemption.
 
  The signature and date provided on the Substitute Form W-9 will serve to
certify that the TIN and withholding information provided in this Form of
Election are true, correct, and complete. Please consult your tax advisor for
further guidance in completing the Substitute Form W-9.

Agent will make the allocations of cash and Technitrol Shares to be received
by holders of Pulse Common Stock or their designees in accordance with the
Election and Allocation Procedures. The Exchange Agent will thereafter issue

surrendering such certificates at that time. After the Exchange Agent receives
your stock certificates with a properly completed Letter of Transmittal, it
will issue and mail to you a check for any cash and/or any certificate or
certificates for Technitrol Shares to which you are entitled (and, if
applicable, a check in lieu of a fractional share), provided you have
delivered the required certificates for your Pulse Common Stock in accordance
