5. Amendments, etc. with respect to the Obligations; Waiver of Rights. Each Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment of any of the Obligations made by the Trustee or any Holder may be rescinded by such party and any of the Obligations continued, and the Obligations, or the liability of any other party upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Trustee, the Collateral Agent or the Holders pursuant to the provisions of the Indenture and the Indenture, the Notes, the other Indenture Documents or other guarantee or document in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, pursuant to the provisions of the Indenture, and any collateral security, guarantee or right of offset at any time held by the Trustee or the Collateral Agent for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the Trustee nor the Collateral Agent shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for this Guarantee or any property subject thereto. When making any demand hereunder against any particular Guarantor, the Trustee or, subject to Sections 7.06 and 7.07 of the Indenture, any Holder may, but shall be under no obligation to, make a similar demand on any other Guarantor or guarantor, and any failure by the Trustee or, subject to Sections 7.06 and 7.07 of the Indenture, such Holder to make any such demand or to collect any payments from any such other Guarantor or guarantor or any release of any such other Guarantor or guarantor shall not relieve such Guarantor in respect of which a demand or collection is not made or any of the Guarantors not so released of their several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Trustee or any Holder against any of the Guarantors. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

6. Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations guaranteed by such Guarantor, and notice of or proof of reliance by the Trustee or any Holder upon this Guarantee or acceptance of this Guarantee; the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon this Guarantee; and all dealings between the Issuers or any of the other Guarantors and the Trustee, the Collateral Agent or any Holder shall likewise be conclusively presumed to have been had or consummated in reliance upon this Guarantee. Each Guarantor waives diligence,

presentment, protest, demand for payment and notice of default or nonpayment to or upon the Issuers or any of the other Guarantors with respect to the Obligations guaranteed by such Guarantor. Each Guarantor understands and agrees that this Guarantee shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (a) the validity, regularity or enforceability of the Indenture, the Notes, any other Indenture Document, any of the Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by the Trustee or the Collateral Agent, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by the Issuers, any of the other Guarantors or any other Person against the Trustee or any Holder, or (c) any other circumstance whatsoever (with or without notice to or knowledge of the Issuers or such other Guarantor) which constitutes, or might be construed to constitute, an equitable or legal discharge of the Issuers for the Obligations, or of any Guarantor under this Guarantee, in bankruptcy or in any other instance. When pursuing its rights and remedies hereunder against any Guarantor, the Trustee, the Collateral Agent and/or any Holder may, but shall be under no obligation to, pursue such rights and remedies as it may have against the Issuers or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure by the Trustee, the Collateral Agent or any Holder to pursue such other rights or remedies or to collect any payments from the Issuers or any such other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of the Issuers or any such other Person or any such collateral security, guarantee or right of offset, shall not relieve such Guarantor of any liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Trustee, the Collateral Agent or any Holder against such Guarantor. This Guarantee shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon each Guarantor and the successors and assigns thereof, and shall inure to the benefit of the Trustee and the Holders, and their respective successors, indorsees, transferees and assigns, until all the Obligations and the obligations of each Guarantor under this Guarantee shall have been satisfied by payment in full or the release of the Guarantor in accordance with Section 7.

7. Release of Guarantor. In the event of:

(a) the defeasance or discharge of the Notes in accordance with Section 9.02 of the Indenture or Section 4.01 of the Indenture, respectively;

(b) a sale or other disposition of all or substantially all of the assets of a Guarantor, by way of merger, consolidation or otherwise, to a Person or a group of Persons that is not (either before or after giving effect to such transaction) a Restricted Subsidiary, or the sale or other disposition of Capital Stock of a Guarantor such that such entity ceases to constitute a Subsidiary of an Issuer, in each case, if the sale or other disposition complies with Section 5.10 of the Indenture or Section 6.01 of the Indenture;

(c) a sale or other disposition of all of the Capital Stock of a Guarantor, including by way of merger, consolidation or otherwise, to a Person or a group of Persons that is not (either before or after giving effect to such transaction) a Restricted Subsidiary, if the sale or other disposition complies with Section 5.10 of the Indenture or Section 6.01 of the Indenture; or

(d) the designation of any Guarantor as an Unrestricted Subsidiary in accordance with the terms of the Indenture; such Guarantor (and any of its Subsidiaries that are Guarantors) shall be released and relieved of any obligations under this Guarantee. Upon delivery by the Issuers to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such defeasance or discharge or such sale or other disposition or designation was made by the Issuers in accordance with the provisions of the Indenture, including Section 5.10 of the Indenture, as applicable, the Trustee and the Collateral Agent shall execute any documents reasonably required by the Issuers or such Guarantor in order to evidence the release of any Guarantor from its obligations hereunder.

Any Guarantor not released from its obligations hereunder shall remain liable for the full amount of principal of, premium, if any, and interest on the Notes and for the other obligations of any Guarantor under the Indenture Documents as provided herein.

8. Reinstatement. This Guarantee shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of the Obligations is rescinded or must otherwise be restored or returned by the Trustee, the Collateral Agent or any Holder upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Issuers or of any other Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Issuers or any other Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

11. Severability. Any provision of this Guarantee which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

12. Section Headings. The section headings used in this Guarantee are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

No failure to exercise, nor any delay in exercising, on

the part of the Trustee or any Holder, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Trustee or any Holder of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Trustee or such Holder would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law.

14. Integration; Waivers and Amendments; Successors and Assigns.

FORM OF JOINDER TO NOTE GUARANTEE

This JOINDER (this “Agreement”), dated as of ___________ __, 20__, is made by Stratus Technologies, Inc., a Delaware corporation (the “U.S. Issuer”) and Stratus Technologies Bermuda Ltd. (the “Bermuda Issuer” and, together with the U.S. Issuer, the “Issuers”), _____________, a[n] ___________ ___________ (the “New Guarantor”).

PRELIMINARY STATEMENT

A. The Issuers are party to an Indenture, dated as of April 8, 2010 (the “Indenture”), by and among the Issuers and The Bank of New York Mellon Trust Company, N.A., as trustee (in such capacity, the “Trustee”) and collateral agent (in such capacity, the “Collateral Agent”), pursuant to which the Issuers have issued units, each unit consisting of $480 principal amount of 12% Senior Secured Notes due 2015 (the “Bermuda Notes”) issued by the Bermuda Issuer and $520 principal amount of 12% Senior Secured Notes due 2015 (the “U.S. Notes” and, together with the Bermuda Notes, the “Notes”) issued by the U.S. Issuer. Capitalized terms used herein but not otherwise defined shall have the meanings assigned to them in the Indenture.

B. Section 5.17 of the Indenture provides that under certain circumstances, the New Guarantor shall execute and deliver to the Trustee a joinder to the Note Guarantee pursuant to which it shall unconditionally guaranty all of the Issuers’ obligations under the Notes and the Indenture and agree to perform the obligations of a Guarantor under the Note Guarantee.

C. The Issuers and the New Guarantor have agreed to this and execute this Agreement for the purpose of evidencing such agreement.

NOW THEREFORE, in consideration of the premises and the mutual covenants herein contained, the Issuers and the New Guarantor hereby agree for the benefit of the Trustee, the Collateral Agent and the Holders as follows:

1. Joinder to the Note Guarantee. The New Guarantor hereby agrees that, upon its execution hereof, it will become a Guarantor under the Note Guarantee and will be bound by the terms, conditions and other provisions applicable to a Guarantor under the Note Guarantee, the Indenture and the other Indenture Documents. Without limitation of the foregoing, and in furtherance thereof, the New Guarantor unconditionally and irrevocably guarantees the due and punctual payment and performance when due of all Obligations (on the same basis as the other Guarantors under the Note Guarantee).
