opinion and the form and substance thereof) that the transfer of Security: 
(i) may be effected without registration under the Securities Act, and (ii) does
not cause the violation of any state securities law (including any investment
suitability standards) applicable to Seller.

      (l) Subscriber may be precluded from selling or otherwise transferring or

demand. This Note is one of a number of 10% Series A Convertible Notes issued by
the Company in a private placement of up to $6,000,000 aggregate principal
amount of 10% Series A Convertible Notes (this Note and such other 10% Series A
Convertible Notes are collectively referred to herein as the "10% Series A
Convertible Notes"). The terms and conditions of all 10% Series A Convertible
Notes shall be identical in all respects and all 10% Series A Convertible Notes
shall rank pari passu.

   Payments of principal and interest on this Note shall be made in lawful money
of the United States of America by delivery of a check to the address provided
by the payee as shown on the Note Register. The Company may treat the person in
whose name this Note is registered (the "Holder") on the Note Register kept by
the Company as the owner of this Note for the purpose of receiving payment and
for all other purposes, and the Company shall not be affected by any notice to
the contrary. This Note is transferable only (i) in accordance with the terms
hereof and (ii) by surrender thereof at the office of the Company at 185
Monmouth Parkway, West Long Branch, New Jersey, duly endorsed or accompanied by
a written instrument duly executed by the Holder of this Note or his attorney
duly authorized in writing.

   The Company shall have the right, exercisable on not less than 15 days
written notice to the Holder, at any time after the date hereof, to prepay the
unpaid principal balance under this Note in whole or in any part, without
penalty or premium and with the interest due to the date of prepayment,
provided, however, that the Company shall at the same time prepay an equal
unpaid principal amount of all other outstanding 10% Series A Convertible Notes.
Any notice of prepayment shall be delivered to the Holder at its registered
address appearing on the


                                        1


records of the Company and shall state (1) that the Company is exercising its
right to prepay all or a portion of the principal of this Note, (2) the
principal amount to be repaid and (3) the date of prepayment. Upon the
prepayment of less than the entire unpaid principal amount of this Note, a new
Note containing the same date and provisions as this Note shall be issued by the
Company to the Holder for the principal balance of this Note which shall not
have been prepaid. In addition to, and not in limitation of, the foregoing, in
the event of an equity or debt financing conducted by the Company after the date
hereof, the Company shall, promptly following receipt thereof, apply fifty
percent (50%) of the amount, if any, by which the aggregate net proceeds
received by the Company from any such equity or debt financing exceeds twenty
million dollars ($20 Million), to the repayment of outstanding principal and
interest on all 10% Series A Convertible Notes, pari passu, to each holder's 10%
Series A Convertible Note. This provision shall not apply to equity or debt
financings to the extent that proceeds from such financings are utilized for
acquisitions of other businesses.

      The Holder shall have the option to have interest payments made to it in
fully paid and non-assessable shares of Common Stock of EA ("EA Shares") or
fully-paid and non-assessable shares of Common Stock of the Tanon Manufacturing,
Inc. ("Tanon Shares"). The terms EA Shares and Tanon Shares are sometimes
collectively referred to herein as the "Shares." This option may be exercised on
any one or more of the dates interest is payable under this Note by delivery of
written notice to the Company at least fifteen (15) days before such payment
date. If this option is elected, EA or the Company shall issue and dispatch to
the Holder one or more Certificates for the aggregate number of whole Shares of
Common Stock of EA or the Company determined by dividing the Conversion Price
(determined pursuant to paragraph 2 as if the Holder was converting a portion of
the principal of this Note) into the total amount of lawful money of the United
States of America which the Holder would have received if the aggregate amount
of interest on this Note which is being paid in EA Shares or Tanon Shares were
being paid in such lawful money. No fractional shares will be issued in payment
of interest on this Note. In lieu thereof, the Holder may be issued a number of
Shares which reflects a rounding up to the next whole number or may be paid in
lawful money of the United States of America.

   NOTWITHSTANDING THE FOREGOING, PAYMENT OF INTEREST IN EITHER EA SHARES OR
TANON SHARES IS EXPRESSLY CONDITIONED IN EACH CASE UPON (i) SUFFICIENT
AUTHORIZED, UNISSUED AND UNRESERVED COMMON STOCK OF THE ISSUER OF SUCH SHARES TO
PERMIT SUCH PAYMENT, (ii) IN THE CASE OF PAYMENT IN TANON SHARES, COMPLETION OF
AN INITIAL PUBLIC OFFERING OF THE COMMON STOCK OF THE COMPANY PRIOR TO SUCH
PAYMENT, (iii) OFFICIAL NOTICE OF THE LISTING (THE "LISTING") OF SUCH SHARES ON
THE NEW YORK STOCK EXCHANGE OR THE NASDAQ NATIONAL MARKET SYSTEM, IF APPLICABLE,
PRIOR TO SUCH PAYMENT, AND (iv) COMPLIANCE WITH ALL FEDERAL AND STATE SECURITIES
LAWS AND REGULATIONS. IN THE EVENT (i) THERE IS INSUFFICIENT AUTHORIZED,
UNISSUED AND UNRESERVED COMMON STOCK OF THE ISSUER OF THE SHARES TO BE ACQUIRED
UPON AN INTEREST PAYMENT DATE, (ii) IN THE CASE OF PAYMENT IN TANON SHARES, THE
COMPANY HAS NOT COMPLETED AN INITIAL PUBLIC OFFERING OF ITS COMMON STOCK PRIOR
TO AN INTEREST PAYMENT DATE, (iii) SUCH LISTING OF THE SHARES TO BE ACQUIRED
UPON AN INTEREST PAYMENT DATE DOES NOT OCCUR PRIOR TO SUCH DATE, OR (iv) THE
ISSUER OF THE SHARES TO BE ACQUIRED UPON AN INTEREST PAYMENT DATE IS UNABLE TO
COMPLY WITH ALL FEDERAL AND STATE SECURITIES LAWS IN ISSUING SUCH SHARES, SUCH
INTEREST PAYMENT SHALL BE MADE IN U.S. DOLLARS.

1. Restrictions on Transfer of Securities. By accepting this Note, the Holder
hereby acknowledges that, except as expressly set forth herein, neither this
Note nor any Shares issuable in the event of conversion have been, or will be,
registered under the Securities Act of 1933, as amended (the "Securities Act"),
or any state securities laws and represents for himself and his legal
representative that he is acquiring this Note and will acquire any Shares
(hereinafter defined) issued upon conversion hereof, for his own account, for
investment purposes only and not with a view to, or for sale in connection with,
any distribution of such securities, and agrees to reaffirm in writing this
investment representation at the time of exercise of the conversion right set
forth below, subject to the Company's agreement to register the Shares as set
forth in Section 4 below. The Holder shall not


                                       2


transfer this Note or any Shares (or any interest therein) until (i) it shall
have first given written notice to the Company describing the manner of any such
proposed transfer, and (ii) either (a) the Company has received from Holder's
counsel an opinion satisfactory to the Company and its counsel that such
transfer may be made without compliance with the registration provisions of the
Securities Act and that the proposed transfer may be made without violation of
the Securities Act and any applicable state securities law, or (b) a
registration statement filed by the Company covering the Note or Shares to be
transferred is in effect under the Securities Act and there has been compliance
with the applicable state securities laws.

2. Conversion of Note. This Note may be converted into shares of Common Stock of
Tanon Manufacturing, Inc., a California corporation ("Tanon"), or the Company,
as follows:

   (a) Conversion. Subject to and upon compliance with the provisions of this
section captioned "Conversion of Note", at the option of the Holder, at any time
after January 1, 1998 and prior to the close of business on the Maturity Date,
the unpaid principal balance of the Note may be converted in whole, or from time
to time in part, into EA Shares, at a conversion price per EA Share equal to
$3.50 ("EA Conversion Price").

      Subject to and upon compliance with the provisions of this section
captioned "Conversion of Note", at the option of the Holder, at any time after
closing of an initial public offering of the Common Stock of Tanon and prior to
the close of business on the Maturity Date, the unpaid principal balance of the
Note may be converted in whole, or from time to time in part, into Tanon Shares
at a conversion price per Tanon Share equal to the quotient of (i) twenty five
million dollars ($25 million), divided by (ii) the number of shares of Common
Stock of Tanon that were issued and outstanding at the close of business on the
day immediately prior to the effective date of the registration statement
covering the shares of Common Stock of Tanon offered in such initial public
offering, without giving effect to the number of shares of Common Stock of Tanon
being offered in such initial public offering.

      The terms EA Share Price and Tanon Share Price are sometimes collectively
referred to herein as the "Conversion Price." The conversion as set forth herein
shall be subject to such adjustment or adjustments, if any, of such Conversion
Price and of the securities or other property issuable upon such conversion as
set forth below, upon delivery of the Note to the offices of the Company,
together with the form of conversion notice attached thereto (the "Conversion
Notice"), duly executed by the Holder thereof. The Conversion Notice shall state
the principal amount thereof to be so converted, the Shares into which such
amount is being converted and shall include or be accompanied by representations
as to the Holder's investment intent substantially similar to those contained in
this Note. Shares issuable upon conversion of the Note shall be issued in the
name of the Holder and shall be transferable only in accordance with all of the
terms and restrictions contained herein and in the Subscription Agreement of
even date hereof to which the original Holder hereof is a party. Upon such
conversion, Company shall pay, in cash, all accrued and unpaid interest through
the conversion date on the Note or such part thereof delivered for conversion.
No fractional Shares shall be issued or delivered upon conversion of the Note.
In case the Note shall be surrendered for the conversion of only a portion of
the principal amount thereof, the Company shall, at the time of issuing the
Shares issuable upon the conversion of such portion, execute and deliver to the
Holder of the Note so surrendered a new note equal in principal amount to the
unconverted portion of the surrendered Note, dated the most recent date to which
interest shall have been paid on the surrendered Note.

      NOTWITHSTANDING THE FOREGOING, THE CONVERSION OF THE NOTE INTO EITHER EA
SHARES OR TANON SHARES IS EXPRESSLY CONDITIONED IN EACH CASE UPON (i) SUFFICIENT
AUTHORIZED, UNISSUED AND UNRESERVED COMMON STOCK OF THE ISSUER OF SUCH SHARES TO
PERMIT SUCH CONVERSION, (ii) OFFICIAL NOTICE OF THE LISTING (THE "LISTING") OF
SUCH SHARES ON THE NEW YORK STOCK EXCHANGE OR THE NASDAQ NATIONAL MARKET SYSTEM,
IF APPLICABLE, PRIOR TO SUCH CONVERSION, AND (iii) COMPLIANCE WITH ALL FEDERAL
AND STATE SECURITIES LAWS AND REGULATIONS. IN THE EVENT (i) THERE IS
INSUFFICIENT AUTHORIZED, UNISSUED AND


                                       3


UNRESERVED COMMON STOCK OF THE ISSUER OF THE SHARES TO BE ACQUIRED UPON
CONVERSION, (ii) SUCH LISTING OF THE SHARES TO BE ACQUIRED UPON CONVERSION DOES
NOT OCCUR PRIOR THERETO, OR (iii) THE ISSUER OF THE SHARES TO BE ACQUIRED UPON
CONVERSION IS UNABLE TO COMPLY WITH ALL FEDERAL AND STATE SECURITIES LAWS AND
REGULATIONS IN ISSUING SUCH SHARES, THIS NOTE SHALL NOT BE CONVERTIBLE INTO SUCH
SHARES AS AFORESAID.

   (b) Adjustments.

      (i) Subdivision or Combination. Whenever the Company or Tanon shall
subdivide or combine the outstanding shares of its Common Stock issuable upon
conversion of this Note, including stock dividends and stock splits, the
Conversion Price in effect with respect to such Shares being subdivided or
combined immediately prior to such subdivision or combination shall be
proportionately decreased in the case of subdivision or increased in the case of
combination effective at the time of such subdivision or combination.

      (ii) Reclassification or Change. Whenever any reclassification or change
of the outstanding shares of Common Stock of the Company or Tanon shall occur
(other than a change in par value, or from par value to no par, or from no par
to par value, or as a result of a subdivision or combination) effective
provision shall be made whereby the Holder shall have the right, at any time
thereafter, to receive upon conversion of this Note the kind of stock, other
securities or property receivable upon such reclassification or change by a
holder of the number of shares of Common Stock of the Company or Tanon, as the
case may be, issuable upon conversion of this Note immediately prior to such
reclassification or change. Thereafter, the rights of the Holder with respect to
the adjustment of the amount of securities or other property obtainable upon
conversion of this Note shall be appropriately continued and preserved, so as to
afford as nearly as may be possible protection of the nature afforded by this
paragraph (c). The provisions of this clause (iii) shall apply to successive
transactions of the nature to which it relates.

      (iii) Notices of Record Date. In case

           (A) the Company or Tanon shall declare a dividend (or make any other
distribution) on its shares of Common Stock payable otherwise than in cash out
of its earned surplus; or

           (B) the Company or Tanon shall grant the holders of its Common Stock
the right to subscribe for or purchase any shares of its capital stock of any
class; or

           (C) the Company or Tanon shall make any distribution on or in respect
of the Common Stock in connection with the dissolution, liquidation or winding
up of the Company or Tanon; or

           (D) there is to be a reclassification or change of the Common Stock
of the Company or Tanon (other than the subdivision or combination of its
outstanding shares of Common Stock), a consolidation or merger to which the
Company or Tanon is a party and in connection with which approval of any class
of stockholders of the Company or Tanon is required, or a sale or conveyance of
the property of the Company or Tanon as an entirety or substantially as an
entirety, then and in each such event, the Company shall mail or cause to be
mailed to the Holder a notice specifying the date on which any record is to be
taken for the purpose of such dividend, distribution or granting of rights, or
the date on which such reclassification, consolidation or merger is expected to
become effective, and the time, if any, as of which the holders of record of
Common Stock shall be entitled to exchange their shares of Common Stock for
securities or other property deliverable upon such reorganization or
reclassification. Such notice shall be mailed at least 30 days prior to the
record or effective date therein specified.

      (iv) Notice of Adjustment of Conversion Price, etc. If there shall be any
adjustment as provided in (b) hereof, or if securities or property other than
shares of Common Stock of the Company or Tanon shall become issuable or
deliverable in lieu of shares of such Common Stock upon the conversion of this
Note, the Company


                                       4


shall forthwith cause written notice thereof to be sent by registered or
certified mail, postage prepaid, to the Holder, which notice shall be
accompanied by a certificate of the principal financial officer of the Company
setting forth in reasonable detail the facts requiring any such adjustment and
the Conversion Price and number of Shares issuable upon the conversion of this
Note after such adjustment, or the kind and amount of any such securities or
property so issuable or deliverable upon the conversion of this Note, as the
case may be.

3. Default. If any of the following conditions or events ("Events of Default")
shall occur and be continuing:

   (a) if the Company shall default in the payment of principal of this Note
when the same becomes due and payable, whether at maturity or by declaration of
acceleration or otherwise;

   (b) if the Company shall default in the payment of any interest on this Note
and shall fail to cure such default within ten days after receipt of written
notice thereof from the Holder to the Company;

   (c) if the Company shall materially default in the performance of or
compliance with any term contained herein and such default shall not have been
remedied within thirty days after receipt of written notice thereof from the
Holder to the Company;

   (d) if the Company shall make an assignment for the benefit of creditors, or
shall admit in writing its inability to pay its debts as they become due, or a
voluntary petition for reorganization under Title 11 of the United States Code
("Title 11") shall be filed by the Company or an order shall be entered granting
relief to the Company under Title 11 or a petition shall be filed by the Company
in bankruptcy, or the Company shall be adjudicated a bankrupt or insolvent, or
shall file any petition or answer seeking for itself any reorganization,
arrangement, composition, readjustment, liquidation, dissolution or similar
relief under any present or future statute, law or regulation, or shall file any
answer admitting or not contesting the material allegations of a petition filed
against the Company in any such proceeding, or shall seek or consent to or
acquiesce in the appointment of any trustee, receiver or liquidator of the
Company or of all or any substantial part of the properties of the Company or if
the Company or its directors or majority shareholders shall take any action
looking to the dissolution or liquidation of the Company;

   (e) if within 90 days after the commencement of an action against the Company
seeking a reorganization, arrangement, composition, readjustment, liquidation,
dissolution or similar relief under any present or future statute, law or
regulation, such action shall not have been dismissed or nullified or all orders
or proceedings thereunder affecting the operations or the business of the
Company stayed, or if the stay of any such order or proceeding shall thereafter
be set aside, or if, within 90 days after the appointment without the consent or
acquiescence of the Company of any trustee, receiver or liquidator of the
Company or of all or any substantial part of the properties of the Company such
appointment shall not have been vacated; or

   (f) if Tanon shall be in default under the Revolving Credit and Security
Agreement between I.B.J. Schroder Bank & Trust Company and Tanon Manufacturing,
Inc. and such default shall not be cured within 30 days;

then, and in any such event, Holder may at any time (unless such Event of
Default shall theretofore have been remedied) at its option, by written notice
to the Company, declare the Note to be due and payable, whereupon the Note shall
forthwith mature and become due and payable, together with interest accrued
thereon, and thereafter interest shall be due, at the rate of eighteen percent
(18%) per annum on the entire principal balance until the same is fully paid,
and on any overdue interest (but only to the extent permitted by law), without
presentment, demand, protest or notice, all of which are hereby waived.

   In case of a default in the payment of any principal of or interest on the
Note, (whether at maturity or by acceleration) the Company will pay to the
Holder such further amount as shall be sufficient to cover the cost and expenses
of collection, including, without limitation, reasonable attorneys' fees,
expenses and disbursements. No course of dealing and no delay on the part of
Holder in exercising any right shall operate as a waiver thereof or


                                       5


otherwise prejudice such Holder's rights, powers or remedies. No right, power or
remedy conferred by this Note upon Holder shall be exclusive of any other right,
power or remedy referred to herein or now or hereafter available at law, in
equity, by statute or otherwise.

4. Registration Rights.

   (a) Piggyback registration. If the Company or Tanon proposes to file a
registration statement under the Securities Act with respect to an offering by
the Company or Tanon for its own account of its Common Stock (other than a
registration statement on Form S-4, S-8 or S-14 or any form substituting
therefor or filed in connection with an exchange offer or an offering of
securities solely to existing stockholders or employees) during the period
commencing on the date hereof and ending on January 22, 1999, the Company or
Tanon shall in each case give written notice of such proposed filing to the
Holder and such notice shall offer the Holder the opportunity to register such
number of Shares as the Holder has acquired or contemplates acquiring upon
conversion and requests in writing within ten days after receipt of such notice.
If such offering is an underwritten offering, the amount of Shares included by
Holder may be reduced in the sole discretion of the managing underwriter. In
connection with a piggy-back registration pursuant to this subsection 4(a), the
Company or Tanon will bear all registration expenses, except sales commissions
and the fees and expenses of counsel to the Holder which shall be borne by
Holder. The Holder shall deliver such documents, and provide the Company or
Tanon with such information, as is necessary or desirable to effectuate such
registration.

   (b) Demand Rights. In addition, upon written notice at any time beginning on
January 1, 1998 (with respect to EA Shares) or immediately after closing of an
initial public offering of the Common Stock of Tanon (with respect to Tanon
Shares) and in both cases ending on January 22, 1999, from holders of at least
$500,000 in aggregate principal of the 10% Series Convertible Notes that he, she
or it contemplates conversion and transfer of all or any of his, her or its
Shares under such circumstances that a public offering, within the meaning of
the Securities Act of such Securities will be involved, the Company or Tanon,
depending on which entity will issue the underlying Shares, as promptly as
possible after the receipt of such notice, shall file at its expense a
post-effective amendment or a new registration statement under the Securities
Act with respect to the offering and sale or other disposition of the subject
Shares with respect to which it shall have received such notice. Within 10 days
after receiving any such notice, the Company shall give notice to the other
holders of 10% Series A Convertible Notes advising them that the Company or
Tanon is proceeding with such registration and offering to include therein the
underlying Shares of such holders. If audited interim financial statements are
required to be prepared for use in connection with the registration statement,
the holders of 10% Series A Convertible Notes will bear the expense. The holders
of 10% Series A Convertible Notes will also bear the expense of fees of counsel
for the holders and sales commissions on the underlying Shares of such holders.
The Company or Tanon, depending on which entity will issue the underlying
Shares, agrees to use its best efforts to cause the registration statement to
become effective. In no event shall the Company or Tanon be required to file a
registration statement pursuant to the requirements of this subsection (b) more
than once.

   (c) In the event that the Company or Tanon shall take action to permit a
public offering or sale or other distribution of the Shares pursuant to
Subsection 4(a) or (b) above, the Company shall:

      (i) Supply to the Holder two executed copies of each registration
statement and a reasonable number of copies of the preliminary, final and other
prospectus or offering circular in conformity with requirements of the
Securities Act and the Rules and Regulations promulgated thereunder and such
other documents as the Holder shall reasonably request.

      (ii) Cooperate in taking such action as may be necessary to register or
qualify the Shares under such other securities acts or blue sky laws of such
jurisdictions as the Holder shall reasonably request and to do any and all other
acts and things which may be necessary or advisable to enable the Holder of such
Shares to consummate such proposed sale or other disposition of the Shares in
any such jurisdiction; provided, however,


                                       6


that in no event shall the Company or Tanon be obligated, in connection
therewith, to qualify to do business or to file a general consent to service of
process in any jurisdiction where it shall not then be qualified.

      (iii) Indemnify and hold harmless Holder and each underwriter, within the
meaning of the Act, who may purchase from or sell for Holder, any Shares, from
and against any and all losses, claims, damages, and liabilities (including, but
not limited to, any and all expenses whatsoever reasonably incurred in
investigating, preparing, defending or settling any claim) arising from (A) any
untrue statement of a material fact contained in a registration statement
furnished pursuant to of this Section 4, or any prospectus or offering circular
included therein, or (B) any omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading
(unless such untrue statement or omission was based upon information furnished
or required to be furnished in writing to the Company by such Holder or
underwriter expressly for use therein), which indemnification shall include each
person, if any, who controls any such Holder or underwriter, within the meaning
of the Securities Act; provided, however, that the Company shall not be so
obligated to indemnify any such Holder or underwriter or controlling person
unless such Holder and underwriter shall at the same time indemnify the Company,
Tanon, their respective directors, each officer signing any registration
statement or any amendment to any registration statement and each person, if
any, who controls the Company or Tanon within the meaning of the Securities Act,
from and against any and all losses, claims, damages and liabilities (including,
but not limited to, any and all expenses whatsoever reasonably incurred in
investigating, preparing, defending or settling and claim) arising from (C) any
untrue statement of a material fact contained in any registration statement or
any amendment to any registration statement or prospectus or offering circular
furnished pursuant to of this Section 4, or (D) any omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, but the indemnity of such Holder, underwriter or
controlling person shall be limited to liability based upon untrue statements of
a material fact or omission to state a material fact required to make such
statements not misleading contained within information furnished in writing to
the Company by such Holder or underwriter or controlling person expressly for
use therein. The indemnity agreement of the Company herein shall not inure to
the benefit of any such underwriter (or to the benefit of any person who
controls such underwriter) on account of any losses, claims, damages,
liabilities (or actions or proceedings in respect thereof) arising from the sale
of any of such Shares by such underwriter to any person if such underwriter
failed to send or give a copy of the prospectus or offering circular furnished
pursuant to of this Section 4, as the same may then be supplemented or amended,
to such person with or prior to the written confirmation of the sale involved.

      (iv) Keep effective for a period of not less than three (3) months nor
more than (9) months after the initial effectiveness thereof all such
registrations under the Securities Act.

   (d) The Company's obligation under Subsection (a) and (b) shall be
conditioned upon a timely receipt by the Company in writing of:

           (i)  Information as to the terms of such public offering furnished
by or on behalf of Holder intending to make a public distribution of his
Shares; and

           (ii) Such other information as the Company may reasonably require
from Holder or any underwriter for inclusion in such registration statement or
post-effective amendment.

   Notwithstanding any provision contained in this Note to the contrary, the
Company's liability for payment of interest shall not exceed the limits imposed
by applicable usury law. If any provision hereof requires interest payments in
excess of the then legally permitted maximum rate, such provision shall
automatically be deemed to require such payment at the then legally-permitted
maximum rate.
