Date: March 11, 2008

General Electric Capital Corporation

4225 Executive Square, Suite 800

La Jolla, CA 92037

To induce you, but not bind you, to enter into Schedule Nos. 002 and 003, each dated on or about March 11, 2008, to that certain Lease Agreement dated as of November 7, 2006 (the “2006 Lease”) between you and Semiconductor Components Industries, LLC, a Delaware limited liability company (“Customer”), which is a wholly owned subsidiary of the undersigned, (Schedule Nos. 002 and 003, together with the 2006 Lease only insofar as it relates to Schedule Nos. 002 and 003, and any other documents relating to Schedule Nos. 002 and 003 are hereinafter referred to collectively as the “Account Documents” and each an “Account Document”) the undersigned, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, does hereby guarantee to you, your successors and permitted assigns, the due regular and punctual payment of any sum or sums of money which the Customer may owe to you now or at any time hereafter pursuant to the Account Documents, whether it represents principal, interest, rent, late charges, indemnities, an original balance, an accelerated balance, liquidated damages, a balance reduced by partial payment, a deficiency after sale or other disposition of any leased equipment, collateral or security, or any other type of sum of any kind whatsoever that the Customer may owe to you now or at any time hereafter pursuant to the Account Documents, and does hereby further guarantee to you, your successors and permitted assigns, the due, regular and punctual performance of any other duty or obligation of any kind or character whatsoever that the Customer may owe to you now or at any time hereafter pursuant to the Account Documents (all such payment and performance obligations being collectively referred to as “Obligations”). For the avoidance of doubt, this Guaranty in no way relates to Customer’s obligations under that certain Schedule No. 001 dated as of November 7, 2006 to the 2006 Lease, and to the extent that Customer makes any payment under the 2006 Lease, such payment shall be presumed to be in respect of the Account Documents, absent evidence to the contrary. Undersigned does hereby further guarantee to pay upon demand all losses, costs, attorneys’ fees and expenses which may be suffered by you by reason of Customer's default under the Account Documents or default of the undersigned under this Guaranty. As used in this Guaranty, “you” shall mean General Electric Capital Corporation and all its subsidiaries.

Notwithstanding anything to the contrary contained herein, the maximum liability of the undersigned pursuant to this Guaranty shall be an amount equal to the sum of (i) the aggregate amount of Rent (as such term is defined in the Account Documents) that is past due and unpaid under the Account Documents as of the date you demand payment from the undersigned pursuant to this Guaranty, (ii) the aggregate Stipulated Loss Value (as such term is defined in the Account Documents) of all units of Equipment leased pursuant to the Account Documents calculated as of the date you demand payment from the undersigned pursuant to this Guaranty, plus (iii) all reasonable attorneys’ fees and expenses incurred by you by reason of the undersigned’s breach of its obligations under this Guaranty.

This Guaranty is a guaranty of prompt payment and performance (and not merely a guaranty of collection). Nothing herein shall require you to first seek or exhaust any remedy against the Customer, its successors and assigns, or any other person obligated with respect to the Obligations, or to first foreclose, exhaust or otherwise proceed against any leased equipment, collateral or security which may be given in connection with the Obligations. It is agreed that you may, upon any breach or default of the Customer, or at any time thereafter, make demand upon the undersigned and receive payment and performance of the Obligations, with or without notice or demand for payment or performance by the Customer, its successors or assigns, or any other person. Suit may be brought and maintained against the undersigned, at your election, without joinder of the Customer or any other person as parties thereto. To the extent that there is more than one signatory to this Guaranty, the obligations of each such signatory to the Guaranty, and each other guarantor (if any) of the Obligations, shall be joint and several.

The undersigned agrees that its obligations under this Guaranty shall be primary, absolute, continuing and unconditional, irrespective of and unaffected by any of the following actions or circumstances (regardless of any notice to or consent of the undersigned): (a) the genuineness, validity, regularity and enforceability of the Account Documents or any other document; (b) any extension, renewal, amendment, change, waiver or other modification of the Account Documents or any other document; (c) the absence of, or delay in, any action to enforce the Account Documents, this Guaranty or any other document; (d) your failure or delay in obtaining any other guaranty of the Obligations (including, without limitation, your failure to obtain the signature of any other guarantor hereunder); (e) the release of, extension of time for payment or performance

1

by, or any other indulgence granted to the Customer or any other person with respect to the Obligations by operation of law or otherwise; (f) the existence, value, condition, loss, subordination or release (with or without substitution) of, or failure to have title to or perfect and maintain a security interest in, or the time, place and manner of any sale or other disposition of any leased equipment, collateral or security given in connection with the Obligations, or any other impairment (whether intentional or negligent, by operation of law or otherwise) of the rights of the undersigned; (g) the Customer’s voluntary or involuntary bankruptcy, assignment for the benefit of creditors, reorganization, or similar proceedings affecting the Customer or any of its assets; or (h) any other action or circumstances which might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor. Notwithstanding the forgoing, the undersigned expressly reserves the right to assert as a defense Lessee’s payment or performance of the Obligations.

This Guaranty, the Account Documents and the Obligations may be assigned by you, without the consent of the Undersigned, provided such assignment is effected pursuant to the terms of the Account Documents. The Undersigned agrees that if it receives written notice of an assignment from you, the Undersigned will pay all amounts due hereunder to such assignee or as instructed by you. The Undersigned also agrees to confirm in writing receipt of the notice of assignment as may be reasonably requested by assignee. The Undersigned hereby waives and agrees not to assert against any such assignee any of the defenses set forth in the immediate preceding paragraph.

This Guaranty may be terminated upon delivery to you (at your address shown above) of a written termination notice from the undersigned. However, as to all Obligations (whether matured, unmatured, absolute, contingent or otherwise) incurred by the Customer prior to your receipt of such written termination notice (and regardless of any subsequent amendment, extension or other modification which may be made with respect to such Obligations), this Guaranty shall nevertheless continue and remain undischarged until all such Obligations are indefeasibly paid and performed in full.

The undersigned agrees that this Guaranty shall remain in full force and effect or be reinstated (as the case may be) if at any time payment or performance of any of the Obligations (or any part thereof) is rescinded, reduced or must otherwise be restored or returned by you, all as though such payment or performance had not been made. If, by reason of any bankruptcy, insolvency or similar laws effecting the rights of creditors, you shall be prohibited from exercising any of your rights or remedies against the Customer or any other person or against any property, then, as between you and the undersigned, such prohibition shall be of no force and effect, and you shall have the right to make demand upon, and receive payment from, the undersigned of all amounts and other sums that would be due to you upon a default with respect to the Obligations.

Notice of acceptance of this Guaranty and of any default by the Customer or any other person is hereby waived. Presentment, protest demand, and notice of protest, demand and dishonor of any of the Obligations, and the exercise of possessory, collection or other remedies for the Obligations, are hereby waived. The undersigned warrants that it has adequate means to obtain from the Customer on a continuing basis financial data and other information regarding the Customer and is not relying upon you to provide any such data or other information. Without limiting the foregoing, notice of adverse change in the Customer’s financial condition or of any other fact which might materially increase the risk of the undersigned is also waived. All settlements, compromises, accounts stated and agreed balances made in good faith between the Customer, its successors or assigns, and you shall be binding upon and shall not affect the liability of the undersigned.

Payment of all amounts now or hereafter owed to the undersigned by the Customer for any of the Obligations is hereby subordinated in right of payment to the indefeasible payment in full to you of all Obligations and is hereby assigned to you as a security therefor. The undersigned hereby irrevocably and unconditionally waives and relinquishes all statutory, contractual, common law, equitable and all other claims against the Customer for any of the Obligations, any collateral therefor, or any other assets of the Customer, for subrogation, reimbursement, exoneration, contribution, indemnification, setoff or other recourse in respect of sums paid or payable to you by the undersigned hereunder, and the undersigned hereby further irrevocably and unconditionally waives and relinquishes any and all other benefits which it might otherwise directly or indirectly receive or be entitled to receive by reason of any amounts paid by, or collected or due from, it, the Customer for any of the Obligations, or realized from any of their respective assets.

THE UNDERSIGNED HEREBY UNCONDITIONALLY WAIVES ITS RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF, DIRECTLY OR INDIRECTLY, THIS GUARANTY, THE OBLIGATIONS GUARANTEED HEREBY, ANY OF THE RELATED DOCUMENTS, ANY DEALINGS BETWEEN US RELATING TO THE SUBJECT MATTER HEREOF OR THEREOF, AND/OR THE RELATIONSHIP THAT IS BEING ESTABLISHED BETWEEN US. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT (INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS). THIS WAIVER IS IRREVOCABLE MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS

Nor are there any conditions to the full effectiveness of this Guaranty. This Guaranty and each of its provisions may only be waived, modified, varied, released, terminated or surrendered, in whole or in part, by a duly authorized written instrument signed by you. No failure by you to exercise your rights hereunder shall give rise to any estoppel against you, or excuse the undersigned from performing hereunder. Your waiver of any right to demand performance hereunder shall not be a waiver of any subsequent or other right to demand performance hereunder.

This Guaranty shall be governed by, or construed in accordance with, the laws of the State of Connecticut.
