                              TERMINATION AGREEMENT


      TERMINATION AGREEMENT (this "Agreement") made as of May 3, 2002, by and
between Dario Sacomani ("Sacomani") and Semiconductor Components Industries, LLC
dba ON Semiconductor, a Delaware corporation, and all of its affiliates
("Company").

      WHEREAS, the Company engaged Sacomani as its Senior Vice President, Chief
Financial Officer and Treasurer pursuant to an employment agreement dated as of
October 27, 1999, and amended ("Amendment") such agreement on November 28, 2001
("Employment Agreement");

      WHEREAS, all capitalized terms not otherwise defined in this Agreement
shall have the meanings ascribed to such terms in the Employment Agreement;

      WHEREAS, the parties wish to confirm the termination of Sacomani's
employment with the Company and set forth their agreement as to the manner in
which Sacomani's employment with the Company will be closed out;

      NOW, THEREFORE, in consideration of the mutual covenants set forth herein
and for other good and valuable consideration, receipt of which is hereby
acknowledged, the Company and Sacomani agree as follows:

            1.    CONFIRMATION OF TERMINATION.  The Parties hereby now
acknowledge and confirm that the employment and related Employment Period has
terminated effective as of May 1, 2002 ("Termination Date").

            2.    TERMINATION PAYMENTS AND OTHER CONSIDERATION.

            (a) No later than thirty (30) days after the Effective Date of this
Agreement (as defined in Section 10(c) hereof), the Company shall pay Sacomani a
total of Eight Hundred Ninety Six Thousand Seventy Four Dollars ($896,074.00)
[the sum of $520,000.00 plus $376,074.00] consisting of the follows:

                  (i) Pursuant to Section 5(a) of the Employment Agreement, Five
            Hundred Twenty Thousand Dollars ($520,000.00) which represents two
            (2) times the highest rate of Sacomani's annualized Base Salary in
            effect any time up to and including the Termination Date (Two
            Hundred Sixty Thousand Dollars [$260,000.00]); plus

                  (ii) Three Hundred Seventy Six Thousand Seventy Four Dollars
            ($376,074.00) which represents two (2) times Sacomani's annual bonus
            under the Company's former Key Contributors Incentive Plan (KCIP)
            earned in respect of Fiscal Year 2000 and paid in 2001 (One Hundred
            Eighty Eight Thousand Thirty Seven Dollars [$188,037.00]).

            (b) In addition to the cash payments described in Section 2(a)
above, the Company agrees to the following other consideration ("Other
Consideration"):



                                                                               1
<PAGE>
                  (i) Pursuant to Section 5(a) of the Employment Agreement, all
            shares underlying the Option (as defined in the Employment
            Agreement) shall become immediately exercisable as of the
            Termination Date. The Option was granted on September 9, 1999 under
            the 1999 Founders Stock Option Plan ("Option Plan") and related
            stock option grant agreement with respect to Four Hundred Thirty
            Three Thousand Three Hundred Thirty Three (433,333) shares of the
            Company's common stock (after the Company's reverse stock split of
            February 17, 2000).

                  (ii) Pursuant to Section II(c) of the Amendment, all current
            stock options that are granted to Sacomani (to the extent they are
            or become exercisable on the Termination Date) will remain fully
            exercisable until the first to occur of (A) the last day of the two
            (2) year period immediately following the Termination Date, and (B)
            the tenth anniversary of the grant date of such option.

                  (iii) Through December 31, 2002, the Company will pay the
            total cost for the continuation of medical benefits for Sacomani and
            his immediate family under the Company's group medical plan as
            amended from time to time and for which Sacomani is eligible
            pursuant to a valid COBRA election timely made by Sacomani. The
            foregoing notwithstanding, in the event that Sacomani becomes
            eligible for comparable medical benefits in connection with new
            employment during the period from the Termination Date through
            December 31, 2002, the coverage provided by the Company under this
            Subsection 2(b)(iii) shall terminate immediately. Sacomani agrees
            that he will notify the Company promptly of his subsequent
            employment and eligibility for benefits.

            (c) The Termination Payments and Other Consideration (described in
Sections 2(a) and 2(b) above) shall be reduced by any required tax withholdings.
The Termination Payments and Other Consideration shall not be taken into account
as compensation and no service credit shall be given after the Termination Date
for purposes of determining the benefits payable under any other plan, program,
agreement or arrangement of the Company. Sacomani acknowledges that, except for
the Termination Payments and Other Consideration agreed to herein, he is not
entitled to any payment in the nature of severance or termination pay from the
Company. For the avoidance of doubt, this Agreement does not effect the
Company's obligations under the Company's Executive Deferred Compensation Plan,
under which Sacomani has an accrued balance as of May 1, 2002 of $107,208.06.

            3.    GENERAL RELEASE AND WAIVER.

            (a) SACOMANI HEREBY RELEASES, REMISES AND ACQUITS THE COMPANY AND
ALL OF ITS AFFILIATES, AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES,
MEMBERS, PARTNERS, SHAREHOLDERS, SUCCESSORS AND ASSIGNS (COLLECTIVELY REFERRED

OR UNKNOWN, WHICH SACOMANI OR SACOMANI'S HEIRS, SUCCESSORS OR ASSIGNS HAVE OR

LIABILITIES ARISING FROM ANY AND ALL BASES, HOWEVER DENOMINATED, INCLUDING BUT

            (c) The Company's senior executives are not currently aware of any
facts or circumstances that would give rise to a claim by the Company against
Sacomani. However, the Company is not waiving (and the foregoing representation
should not be construed as a waiver of) any claim against Sacomani in the event
the Company or its senior executives learn of any facts or circumstances
(whether occurring prior to or after the date hereof) that give rise to any such
claim against Sacomani and in the event the Company learns of any such facts or
circumstances this Agreement shall not be a bar to any such claim.

            4.    RESTRICTIVE COVENANTS.

            Sacomani hereby acknowledges and agrees that he shall be subject to
the Restrictive Covenants and provisions of Sections 8, 9 and 10 of the
Employment Agreement and such provisions shall remain in full force and effect
as if fully stated herein pursuant to their terms.



                                                                               3

            Sacomani may retain his mobile telephone, wireless pager and

and proprietary information in a manner reasonably satisfactory to the Company.
In addition, Sacomani shall return any and all other Company property and
confidential or proprietary information (in whatever form) to the Company on or
before the Effective Date.

            6.    ACKNOWLEDGEMENT OF CONDITIONAL PAYMENTS.

            Sacomani acknowledges and agrees that the Termination Payments and

subject to Sacomani complying with his obligations under Section 3, 4 and 5
hereof.

            7.    NO ADMISSION.

            This Agreement does not constitute an admission of liability or
wrongdoing of any kind by the Company or its affiliates.

            The terms of this Agreement shall be binding on the parties hereto

            9.    GENERAL PROVISIONS.

            (a)   Integration.

            This Agreement and the Restrictive Covenants provided in Sections 8,
9 and 10 of the Employment Agreement constitute the entire understanding between
the Company and Sacomani with respect to the subject matter hereof and supersede
all prior understandings, written or oral. The terms of this Agreement may be
changed, modified or discharged only by an instrument in writing signed by the
parties hereto. A failure by the Company or Sacomani to insist on strict
compliance with any provision of this Agreement shall not be deemed a waiver of
such provision or any other provision hereof. In the event that any provision of
this Agreement is determined to be so broad as to be unenforceable, such
provision shall be interpreted to be only so broad as is enforceable.

            (b)   Choice of Law.

            This Agreement shall be construed, enforced and interpreted in
ACCORDANCE with and governed by the laws of the State of ARIZONA.

            (c) Construction of Agreement. The parties hereto acknowledge and
agree that each party has reviewed and negotiated the terms and provisions of
this Agreement and has contributed to its revision. Accordingly, the rule of
construction to the effect that ambiguities are resolved against the drafting
party shall not be employed in the interpretation of this Agreement. Rather, the
terms of this Agreement shall be construed fairly as to both parties hereto and
not in favor or against either party.




                                                                               4

            (d)   Counterparts.

            This Agreement may be executed in any number of counterparts and by
different parties on separate counterparts, each of which counterpart, when so
executed and delivered, shall be deemed to be an original and all of which
counterparts, taken together, shall constitute but one and the same Agreement. A
facsimile of a signature shall be deemed to be and have the effect of an
original signature.

            11.   KNOWING AND VOLUNTARY WAIVER.

            (a) Sacomani acknowledges that, by Sacomani's free and voluntary act
of signing below, Sacomani agrees to all of the terms of this Agreement and
intends to be legally bound thereby.

            (b) Sacomani acknowledges that he has received this Agreement on or
before April 15, 2002 and then received a new version of this Agreement
containing amendments that were mutually agreed to by the parties on May 3,
2002. Sacomani understands that he may consider whether to agree to the terms
contained herein for a period of twenty-one (21) days after the date he has
received this Agreement. The parties have mutually agreed that Sacomani may
execute this Agreement after the Termination Date and no later than the close of
business on May 24, 2002, to acknowledge his understanding of and agreement with
the foregoing. However, the Termination Payments and Other Consideration
provided herein will be delayed until this Agreement is executed by Sacomani,
returned to the Company and becomes effective as provided below. Sacomani
acknowledges that he has consulted with an attorney prior to his execution of
this Agreement. (See the acknowledgement at the end of this Agreement).

            (c) This Agreement will become effective, enforceable and
irrevocable on the eighth day after the date on which it is executed by Sacomani
("Effective Date"). During the seven-day period prior to the Effective Date,
Sacomani may revoke his agreement to accept the terms hereof by indicating in
writing to the Company his intention to revoke. If Sacomani exercises his right
to revoke hereunder, he shall not have any right to receive any of the benefits
provided for herein, and to the extent such payments have already been made,
Sacomani agrees that he will immediately reimburse the Company for the amounts
of such payment. Sacomani understands and agrees that the written revocation
notice referred to in this paragraph must be sent to: ON Semiconductor, Attn:
Sonny Cave, General Counsel, Law Department, MD: A700, 5005 E. McDowell Rd.,
Phoenix, AZ 85008 and must be received by the General Counsel at that address
before the end of the seventh day after Sacomani executes this Agreement.
