Item 1.        Description of Securities To Be Registered.

               On March 25, 1998, the Board of Directors of OEA, Inc. (the
"Company") declared a dividend of one common share purchase right (a "Right")
for each outstanding share of common stock, par value $.10 per share (the
"Common Shares"), of the Company. The dividend is payable on April 10, 1998 (the
"Record Date") to the stockholders of record on that date. Each Right entitles
the registered holder to purchase from the Company one one-half of a Common
Share of the Company at a price of $70.00 per one one-half of a Common Share
(the "Purchase Price"), subject to adjustment. The description and terms of the
Rights are set forth in a Rights Agreement (the "Rights Agreement") between the
Company and ChaseMellon Shareholder Services, L.L.C., as Rights Agent (the
"Rights Agent").

               Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (with
certain exceptions for members of the Kafadar family and related entities, the
"Kafadar Entities") (an "Acquiring Person") have acquired beneficial ownership
of 15% or more of the outstanding Common Shares or (ii) 10 business days (or
such later date as may be determined by action of the Board of Directors prior
to such time as any person or group of affiliated persons becomes an Acquiring
Person) following the commencement of, or announcement of an intention to make,
a tender offer or exchange offer the consummation of which would result in the
beneficial ownership by a person or group of 15% or more of the outstanding
Common Shares (the earlier of such dates being called the "Distribution Date"),
the Rights will be evidenced, with respect to any of the Common Share
certificates outstanding as of the Record Date, by such Common Share certificate
with a copy of the Summary of Rights to Purchase Common Shares attached thereto.

               The Rights Agreement provides that, until the Distribution Date
(or earlier redemption or expiration of the Rights), the Rights will be
transferred with and only with the Common Shares. Until the Distribution Date
(or earlier redemption or expiration of the Rights), new Common Share
certificates issued after the Record Date upon transfer or new issuance of
Common Shares will contain a notation incorporating the Rights Agreement by
reference. Until the Distribution Date (or earlier redemption or expiration of
the Rights), the surrender for transfer of any certificates for Common Shares
outstanding as of the Record Date, even without such notation or a copy of the
Summary of Rights being attached thereto, will also constitute the transfer of
the Rights associated with the Common Shares represented by such certificate. As
soon as practicable following the Distribution Date, separate certificates
evidencing the Rights ("Right Cer-


                                       1


tificates") will be mailed to holders of record of the Common Shares as of the
close of business on the Distribution Date and such separate Right Certificates
alone will evidence the Rights.

               The Rights are not exercisable until the Distribution Date. The
Rights will expire on April 30, 2008 (the "Final Expiration Date"), unless the
Final Expiration Date is extended or unless the Rights are earlier redeemed or
exchanged by the Company, in each case, as described below.

               The Purchase Price payable, and the number of Common Shares or
other securities or property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Common
Shares, (ii) upon the grant to holders of the Common Shares of certain rights or
warrants to subscribe for or purchase Common Shares at a price, or securities
convertible into Common Shares with a conversion price, less than the
then-current market price of the Common Shares or (iii) upon the distribution to
holders of the Common Shares of evidences of indebtedness or assets (excluding
regular periodic cash dividends paid out of earnings or retained earnings or
dividends payable in Common Shares) or of subscription rights or warrants (other
than those referred to above).

               In the event that, prior to the redemption, exchange or
termination of the Rights, any person or group of affiliated or associated
persons becomes an Acquiring Person, proper provision shall be made so that each
holder of a Right, other than Rights beneficially owned by the Acquiring Person
(which will thereafter be void), will thereafter have the right to receive upon
exercise that number of Common Shares having a market value of two times the
exercise price of the Right. In the event that, prior to the redemption,
exchange or termination of the Rights, the Company is acquired in a merger or
other business combination transaction or 50% or more of its consolidated assets
or earning power are sold after a person or group has become an Acquiring
Person, proper provision will be made so that each holder of a Right (other than
Rights beneficially owned by the Acquiring Person, which will thereafter be
void) will thereafter have the right to receive, upon the exercise thereof at
the then-current exercise price of the Right, that number of shares of common
stock of the acquiring company which at the time of such transaction will have a
market value of two times the exercise price of the Right.

               At any time after any person or group becomes an Acquiring Person
and prior to the acquisition by such person or group of 50% or more of the
outstanding Common Shares, the Board of Directors of the Company may exchange
the Rights (other than Rights owned by such person or group which will have
become 


                                       2


void), in whole or in part, at an exchange ratio of one Common Share per Right.

               With certain exceptions, no adjustment in the Purchase Price will
be required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional Common Shares will be issued and, in lieu
thereof, an adjustment in cash will be made based on the market price of the
Common Shares on the last trading day prior to the date of exercise.

               At any time prior to such time as any person becomes an Acquiring
Person, the Board of Directors of the Company may redeem the Rights in whole,
but not in part, at a price of $.01 per Right (the "Redemption Price"). The
redemption of the Rights may be made effective at such time on such basis with
such conditions as the Board of Directors in its sole discretion may establish.
Immediately upon any redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.

               The terms of the Rights may be amended by the Board of Directors
of the Company without the consent of the holders of the Rights, including an
amendment to lower certain thresholds described above to not less than the
greater of (i) the sum of .001% and the largest percentage of the outstanding
Common Shares then known to the Company to be beneficially owned by any person
or group of affiliated or associated persons (other than the Kafadar
Entities)and (ii) 10%, except that from and after such time as any person or
group of affiliated or associated persons becomes an Acquiring Person no such
amendment may adversely affect the interests of the holders of the Rights.

               Until a Right is exercised, the holder thereof, as such, will
have no rights as a stockholder of the Company, including, without limitation,
the right to vote or to receive dividends.

               The Rights Agreement, dated March 25, 1998, between the Company
and ChaseMellon Shareholder Services, L.L.C., as Rights Agent, specifying the
terms of the Rights is attached hereto as an exhibit and is incorporated herein
by reference. The foregoing description of the Rights is qualified in its
entirety by reference to such exhibit.
