                          STOCK OPTION GRANT AGREEMENT
                          (Non-Qualified Stock Options)

            THIS AGREEMENT, made as of this 22nd day of November 1999 between
SCG Holding Corporation (the "Company") and Richard Boyce (the "Participant").

            WHEREAS, the Company has adopted and maintains the SCG Holding
Corporation 1999 Founders Stock Option Plan (the "Plan") to promote the
interests of the Company and its Affiliates and stockholders by providing the
Company's key employees and others with an appropriate incentive to improve the
growth and profitability of the Company;

            WHEREAS, the Plan provides for the Grant to Participants in the Plan
of Non-Qualified Stock Options to purchase shares of Common Stock of the
Company.

            NOW, THEREFORE, in consideration of the premises and the mutual
covenants hereinafter set forth, the parties hereto hereby agree as follows:

            1. Grant of Options. Pursuant to, and subject to, the terms and
conditions set forth herein and in the Plan, the Company hereby grants to the
Participant a NON-QUALIFIED STOCK OPTION (the "Option") with respect to 615,000
shares of Common Stock of the Company.

            2. Grant Date. The Grant Date of the Option hereby granted is
September 9, 1999.

            3. Incorporation of Plan. All terms, conditions and restrictions of
the Plan are incorporated herein and made part hereof as if stated herein. If
there is any conflict between the terms and conditions of the Plan and this
Agreement, the terms and conditions of this Agreement, as interpreted by the
Board, shall govern. All capitalized terms used and not defined herein shall
have the meaning given to such terms in the Plan.

            4. Exercise Price. The exercise price of each share underlying the
Option hereby granted is $1.00 U.S.

            5. Vesting Date. Subject to the provisions of the Plan, the Option
shall be fully vested and exercisable as of the Grant Date provided above.

            6. Expiration Date. Subject to the provisions of the Plan, the
Option shall expire on the earlier of: (i) 90 days after the Participant's
termination of Employment other than for Cause, death or Disability; (ii) one
year after termination of the Participant's Employment by reason of death or
Disability; (iii) the commencement of business on the date the Participant's
Employment is, or is deemed to have been, terminated for Cause; or (iv) the
tenth anniversary of the Grant Date.

            7. Company Call Rights. Upon a termination of the Participant's
Employment for any reason prior to the existence of a Public Market, the Company
shall have the right, in its sole discretion, during the ninety-day period
immediately following the date of

termination (the "Option Call Period"), to purchase for cash any portion of the
Option that has become exercisable on or before the date of such termination of
Employment for a purchase price equal to the Option Spread, if any, determined
as of the Valuation Date immediately preceding the date that the Company
exercises its right to purchase such Option multiplied by the number of shares
of Common Stock underlying such portion of the Option. Upon written notice that
the Company is exercising its right to purchase such portion of the Option, such
Option shall no longer be exercisable by the Participant (unless otherwise
agreed by the Company) and, upon payment by the Company, such Option shall
immediately become void and cancelled, without any further action by the
Participant or the Company or otherwise. Such payment shall be made within ten
days after the date that the Company notifies the Participant in writing that it
is exercising its right to purchase the Option hereunder, provided that the
Company may delay any such payment in the event such payment will result in the
violation of the terms or provisions of, or result in a default or event of
default under, any guarantee, financing or security agreement or document
entered into by the Company or any of its Affiliates and in effect on such date
(hereinafter a "Financing Agreement"). In the event the payment of the purchase
price is delayed as a result of a restriction imposed by a Financing Agreement
as provided above, such payment shall be made without the application of further
conditions or impediments as soon as practicable after the payment of such
purchase price would no longer result in the violation of the terms or
provisions of, or result in a default or event of default under, any Financing
Agreement, and such payment shall equal the amount that would have been paid to
the Participant if no delay had occurred plus interest for the period from the
date on which the purchase price would have been paid but for the delay in
payment provided herein to the date on which such payment is made (the "Delay
Period"), calculated at an annual rate equal to the average annual prime rate
charged during the Delay Period by a nationally recognized bank designated by
the Board. The Company may deduct from any payment provided hereunder an amount
equal to the applicable federal, state and local withholding taxes.

            8. Construction of Agreement. Any provision of this Agreement (or
portion thereof) which is deemed invalid, illegal or unenforceable in any
jurisdiction shall, as to that jurisdiction and subject to this section, be
ineffective to the extent of such invalidity, illegality or unenforceability,
without affecting in any way the remaining provisions thereof in such
jurisdiction or rendering that or any other provisions of this Agreement
invalid, illegal, or unenforceable in any other jurisdiction. If any covenant
should be deemed invalid, illegal or unenforceable because its scope is
considered excessive, such covenant shall be modified so that the scope of the
covenant is reduced only to the minimum extent necessary to render the modified
covenant valid, legal and enforceable. No waiver of any provision or violation
of this Agreement by the Company shall be implied by the Company's forbearance
or failure to take action.

            9. Delays or Omissions. No delay or omission to exercise any right,
power or remedy accruing to any party hereto upon any breach or default of any
party under this Agreement, shall impair any such right, power or remedy of such
party nor shall it be construed to be a waiver of any such breach or default, or
an acquiescence therein, or of or in any similar breach or default thereafter
occurring nor shall any waiver of any single breach or default be deemed a
waiver of any other breach or default theretofore or thereafter occurring. Any
waiver, permit, consent or approval of any kind or character on the part of any
party of any breach or default under this Agreement, or any waiver on the part
of any party or any provisions or


                                      A-2

conditions of this Agreement, shall be in writing and shall be effective only to
the extent specifically set forth in such writing.

            10. Limitation on Transfer. During the lifetime of the Participant,
the Option shall be exercisable only by the Participant. The Option shall not be
assignable or transferable other than by will or by the laws of descent and
distribution. All shares of Common Stock obtained pursuant to the Option granted
herein shall not be transferred except as provided in the Plan and, where
applicable, the Management Stockholders' Agreement.

            11. Integration. This Agreement, and the other documents referred to
herein or delivered pursuant hereto which form a part hereof contain the entire
understanding of the parties with respect to its subject matter. There are no
restrictions, agreements, promises, representations, warranties, covenants or
undertakings with respect to the subject matter hereof other than those
expressly set forth herein and in the Plan. This Agreement, including without
limitation the Plan, supersedes all prior agreements and understandings between
the parties with respect to its subject matter.

            12. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which shall
constitute one and the same instrument.

            13. Governing Law. This Agreement shall be governed by and construed
and enforced in accordance with the laws of the State of Delaware (United States
of America) without regard to the provisions governing conflict of laws.

            14. Participant Acknowledgment. The Participant hereby acknowledges
receipt of a copy of the Plan. The Participant hereby acknowledges that all
decisions, determinations and interpretations of the Board in respect of the
Plan, this Agreement and the Option shall be final and conclusive. The
Participant further acknowledges that, prior to the existence of a Public
Market, no exercise of the Option or any portion thereof shall be effective
unless and until the Participant has executed the Management Stockholders'
Agreement and the Participant hereby agrees to be bound thereby.


                                      A-3
