(“Sublessor”). Pursuant to that certain Lease dated June 13, 1999, entered into by and between Gateway Sherwood, Inc., a California corporation, by RREEF America LLC, a Delaware limited liability company, its investment advisor (“Lessor”), as landlord, Sublessor’s predecessor-in-interest ADC Broadband Access Systems, Inc. (f/k/a Broadband Access Systems, Inc.), as tenant (“Original Lease”), as amended by the First Amendment to Lease dated October 22, 1999 (“First Amendment”), as further amended by the Second Amendment to Lease dated April 18, 2000 (“Second Amendment”), as further amended by the Third Amendment to Lease dated April 1, 2002 (“Third Amendment”), and as Sublessor’s interest was assigned in Assignment of Lease dated May 24, 2004 (“Assignment”) (with the Original Lease, First Amendment, Second Amendment, Third Amendment and Assignment collectively referred to herein as “Lease”), Sublessor leased from Lessor certain premises in the building located at 8 Technology Drive, Westborough, Massachusetts (“Building”), as more particularly described in the Lease (“Original Premises”). A copy of said Lease is attached hereto, marked Exhibit A. Pursuant to this Sublease, Sublessor has agreed to sublease to Sublessee a, portion of the Original Premises, as more particularly described herein, upon the terms and conditions set forth herein.

Sublessor leases to Sublessee, and Sublessee hires from Sublessor, 63,972 rentable square feet on the first and second floor, as shown on the attached floor plan, marked Exhibit B (“Premises”).

(a) This Sublease is subject to all of the terms and conditions of the Lease, and all amendments thereto; provided, however, Sublessee’s consent must obtained for any and all amendments after the date hereof that materially adversely affect any of Sublessee’s rights thereunder. Sublessee shall in no case have any rights under this Sublease that exceed Sublessor’s rights as tenant under the Lease. Sublessee shall neither do nor permit to be done anything which would constitute a default under the Lease or cause the Lease to be terminated or forfeited by reason of any right of termination or forfeiture reserved or vested in Lessor thereunder. Sublessee shall assume and perform the obligations of Sublessor as tenant in the Lease to the extent said terms and conditions are applicable to the Premises, except as expressly set forth herein. In the event of any conflicts between the terms of the Sublease and the terms of the Lease, for all purposes hereof, the terms of the Sublease shall control; however, to the extent that an issue is not addressed in the Sublease, and also not specifically excluded herein, the terms

1

of the Lease shall control. Sublessee shall not commit or permit to be committed on the Premises any act or omission which shall violate any term or condition of the Lease incorporated under this Sublease. In the event of the termination of Sublessor’s interest as tenant under the Lease for any reason, other than a voluntary termination agreed to by Lessor and Sublessor, then this Sublease shall terminate simultaneously therewith without any liability of Sublessor to Sublessee.

(b) Except as otherwise set forth herein, all of the terms and conditions contained in the Lease are incorporated herein, as terms and conditions of this Sublease (with each reference therein to Lessor, as landlord, and Sublessor, as tenant, to be deemed to refer to Sublessor, as landlord, and Sublessee, as tenant, respectively), and along with all of the following paragraphs set out in this Sublease shall be the complete terms and conditions of this Sublease. The consent of Sublessor shall be required in connection with any act which requires the consent of Lessor, as landlord, pursuant to the Lease, notwithstanding that a particular provision herein may not require Sublessor’s consent or states that only Lessor’s consent is required.

(c) The terms, provisions, covenants, and conditions of the Lease are incorporated herein by reference on the following mutually accepted understandings:

(i) In any case where the Lessor reserves the right to enter the Original Premises pursuant to the Lease, said right shall inure to the benefit of the Lessor as well as to Sublessor with respect to entry onto the Premises.

(ii) With respect to the performance of any other obligations required of Lessor under the Lease, including, but not limited to, work, services, repairs, repainting and restoration, Sublessor’s sole obligation shall be to act on Sublessee’s behalf in requesting the performance of the same of Lessor, after first receiving a request in writing from Sublessee, and to use its best efforts in order to obtain the performance of the same from Lessor.

(iii) Notwithstanding anything in this Sublease or the Lease to the contrary, Sublessee agrees that Sublessor shall not be obligated to furnish for or to Sublessee any service of any nature whatsoever. However, in accordance with provision (ii) above, Sublessor shall act on Sublessee’s behalf in requesting the performance of such services for the Premises by Lessor pursuant to the terms of the Lease.

(iv) Since Lessor’s consent to this Sublease is required pursuant to the terms of the Lease, this Sublease and the obligations of the parties hereto shall be contingent upon Sublessor obtaining the consent of the Lessor to this Sublease. The parties hereto agree to be bound by the terms of this Sublease until such time as such consent of the Lessor has been obtained, or until such consent is deemed to have been granted pursuant to the terms of the Lease. If for any reason such consent of the Lessor is not obtained, this Sublease shall then be null and void and both parties will be released from their obligations hereunder.

2

(v) Notwithstanding anything in this Sublease to the contrary, this Sublease shall not incorporate any provision of the Lease nor shall Sublessee benefit from the rights or privileges contained in any provision of the Lease, which, pursuant to and in accordance with its particular terms and conditions is not applicable to subleases or assignments, or any provision of the Lease, which by its nature or pursuant to a specified prohibition contained in the Lease, is personal to Sublessor or would not convey or transfer by a sublease or assignment of all or a portion of the Original Premises.

Sublessor and Sublessee acknowledge and agree that it is the intent of the parties hereto, that, in no event shall the Term of this Sublease extend for a period longer than the term of the Lease, as such Lease term may be cancelled, terminated or reduced, pursuant to such Lease, by agreement between Lessor and Sublessor, or otherwise.

(b) Early Access: In the event that Sublessor shall permit Sublessee to access the Premises prior to the Commencement Date for the construction of improvements, such access shall be subject to all of the provisions of this Sublease, excepting only the payment of Base Rent; provided, however, Sublessee shall be responsible for reimbursing Sublessor for all utility costs and all costs for any other services used by Sublessee during such period of early access.

Sublessee shall have no option to renew this Sublease or expansion option, right of first refusal, termination option, or other such option under the Lease, if any. Notwithstanding the foregoing, Sublessor agrees to waive any renewal rights under the Lease for the period after the Expiration Date, if Sublessee requests such waiver in writing, to permit Sublessee to negotiate a new lease for the Premises directly with Lessor.

Sublessor shall deliver to Sublessee the Premises in an “As Is, Where Is” condition, excepting same shall be in a broom clean condition, and Sublessee shall be responsible, at its sole cost, for any desired improvements (including, but not limited to, carpeting, partitions, ceiling tiles, wall treatment and/or lighting).

4

HVAC equipment, shall be collectively hereinafter referred to as “Sublessor’s Premises Assets”. If Sublessor’s Premises Assets have been transferred to Sublessee pursuant to that certain Acquisition Agreement by and between Sublessee, Sublessor, and ADC Broadband Access Systems, Inc. dated May         , 2004 (“Acquisition Agreement”), then Sublessee has acquired the Sublessor’s Premises Assets.

Sublessee hereby accepts the premises in their “AS IS” condition existing as of the date Sublessee occupies the Premises, subject to all applicable Laws (as hereinafter defined) governing and relating to the use of the Premises. Sublessee acknowledges that Sublessor has not made any representations or warranty as to the suitability of the Premises for the conduct of Sublessee’s business.

Sublessee shall not make or cause, suffer or permit the making of any alteration, addition, change, replacement, installation or addition (collectively “Alterations”) in or to the Premises unless it obtains the prior written consent of Sublessor in each instance, provides Sublessor with copies of all applicable plans and specifications, and complies with all requirements of the Lease and all applicable Laws (as defined herein). Sublessor’s approval of Sublessee’s plans and specifications for any Alterations shall impose no responsibility or liability on the part of Sublessor for their completeness, design sufficiency, of compliance with all Laws (as hereinafter defined), including, but not limited to, the Americans with Disabilities Act, as amended, and all rules and regulations promulgated thereunder. Sublessee shall be solely responsible for any permits and licenses in order to complete the Alterations. Sublessor shall have no obligations whatsoever to make any repairs or Alterations to the Premises, any systems serving the Premises, or to any equipment, fixtures, or furnishings in the Premises, or to restore the Premises in the event of a fire or other casualty therein.

Sublessee agrees to employ contractors and subcontractors who will guarantee to use first-class materials and workmanship and Sublessee shall not permit any lien to be placed on record with respect to any part of the Building, or the Subleased Premises for work or materials furnished or obligations incurred by or for Sublessee. Sublessee hereby agrees that if any such lien is filed on account of the acts of Sublessee, Sublessee shall discharge any such lien by payment, bond or otherwise, within ten (10) days of recordation of the same. Any Alterations completed by Sublessee shall be completed in accordance with all applicable insurance regulations and Laws (as hereinafter defined), including Environmental Laws (as defined herein) and Sublessee hereby agrees not to use any Hazardous Materials (as defined herein) for such Alterations, which shall include, however, not be limited to, the use of asbestos containing materials.

Notwithstanding anything in the Lease or in this Sublease to the contrary, from and after the Commencement Date, Sublessee shall comply with all statutes, rules, ordinances, orders, codes and regulations, and legal requirements and standards issued thereunder, as the same may be enacted and amended from time to time (collectively referred to in this Sublease as the “Laws”), to the extent the same are applicable to (i) Sublessee’s use or manner of use of the Premises; (ii) any alterations or improvements made by Sublessee; or (iii) any breach by Sublessee hereunder. In the event that Sublessee violates the foregoing obligations, Sublessee shall bear all expense, cost and liability for compliance with such Laws. Sublessee hereby agrees to indemnify, defend and hold Sublessor harmless from all loss, cost, liability or expense, including reasonable attorney fees, resulting from its failure to comply with the provisions of this Section 9.

In addition, Sublessee shall (i) comply with all Environmental Laws (as hereinafter defined); (ii) not cause or permit any Hazardous Materials (as hereinafter defined) to be treated, stored, disposed of, generated, or used in the Premises, provided, however, that Sublessee may store, use or dispose of products customarily found in offices and used in connection with the operation and maintenance of property if Sublessee complies with all Environmental Laws (as hereinafter defined), and does not contaminate the Premises or environment; and (iii) promptly after receipt, deliver to Sublessor, any communication concerning any past or present, actual or potential violation of Environmental Laws (as hereinafter defined), or liability of either party for environmental damages. “Environmental Laws” means all applicable present and future statutes, regulations, rules, final administratively approved unappealable guidelines, ordinances, codes, permits, or orders of all governmental agencies, departments, commissions, boards, bureaus, or instrumentalities of the United States, states and their political subdivisions and all applicable judicial, administrative and regulatory decrees and judgments relating to the protection of the public health or safety of the environment. “Hazardous Materials” include substances (a) which require remediation under Environmental Laws; or (b) which are or become defined as a hazardous waste, hazardous substance, pollutant or contaminant under any Environmental Laws; or (c) which are toxic, explosive, corrosive, flammable, infectious, radioactive, carcinogenic or mutagenic; or (d) which contain petroleum hydrocarbons, polychlorinated byphenyls, asbestos, asbestos containing materials or urea formaldehyde.

The Premises shall be used and occupied only for the uses set forth in the Lease. Notwithstanding the foregoing, in no event shall any use be made of the Premises by or for the benefit of any party in a business which is in competition with the business of Sublessor.

Sublessee shall be permitted to assign or sublet its rights under this Sublease if Sublessee (i) obtains any required consent from Lessor pursuant to the Lease and (ii) obtains the consent of Sublessor, which consent shall not be unreasonably withheld, conditioned or delayed if Lessor so consents.

(a) Pursuant to the Lease, Sublessor may self-insure the coverages provided for therein. This self-insurance option is personal to Sublessor and such right shall not be extended to nor inure to the benefit of Sublessee, and Sublessee shall be required to maintain, at its expense, during the Term of this Sublease the following, unless the Lease requires higher limits and/or additional insurance; in which case the insurance required pursuant to the Lease shall be required in addition to the following: Commercial General Liability Insurance, including contractual liability coverage, with minimum limits of not less than $1,000,000 per occurrence and $4,000,000 in excess per occurrence; all-risk property damage insurance for all of Sublessee’s personal property up to the full replacement value thereof; applicable Worker’s Compensation Insurance with statutory minimum limits; Employer’s Liability Insurance with minimum limits of not less than $1,000,000; and insurance against such other risks and in such other amounts as Sublessor or Lessor may from time to time require.

Prior to the Commencement Date, Sublessee shall provide Sublessor with a certificate of insurance, evidencing such coverages and naming Sublessor and Lessor as additional insureds.

(b) Sublessee shall be responsible for, and shall defend (at Sublessor’s option) indemnify and hold harmless the Sublessor and Lessor against and from, any and all liability or claim of liability arising out of (i) the use or occupancy of, or the conduct, operation or management of the Sublessee’s business in, the Premises, or (ii) any breach or default by the Sublessee in performing any of its obligations under the provisions of this Sublease, the Lease or applicable law, or (iii) any negligent, intentionally tortious or other act or omission of the Sublessee or any of its agents, contractors, servants, employees, subtenants, licensees or invitees during the Term of this Sublease, or (iv) any injury to or death of any person or damage to any property occurring on the Premises during the term of this Sublease, except for claims based on the negligence or willful misconduct of Sublessor or Lessor, or (v) Sublessee’s construction of any Alterations in the Premises.
