(hereinafter "Sublessor"), Analog Microelectronics, Inc. (hereinafter "Sublessee") and Oxford Park Associates (hereinafter "Master Lessor") as a Sublease and consent to sublease (hereinafter "Sublease") subject to the terms and conditions of the Master Lease dated February 24,1998, entered into by Ramp Networks, Inc. and Oxford Park Associates. A copy of said Master Lease is attached hereto, designated Exhibit A, and incorporated herein by this reference. 1. Premises 1.1 Sublessor hereby leases to Sublessee and Sublessee hereby hires from Sublessor, on and subject to the terms and conditions hereinafter set forth, the following described premises (hereinafter referred to as "Subleased Premises"), a portion of the rentable space on the second floor of 3l00 De La Cruz Boulevard, situated in the City of Santa Clara, County of Santa Clara, State of California (hereinafter the "Building") comprising 3,197 rentable square feet of space. 1.2 In addition Sublessee shall have non-exclusive access to the public areas of the building and surrounding area including, but not limited to, the showers on the second floor and parking spaces in the parking lot. 2. Term 2.1 The term of this Sublease (hereinafter "Term") shall start on April 1, 1999 and terminate on March 31, 2001 unless earlier terminated pursuant to any provision hereof, or of the Master Lease. 2.2 Notwithstanding the above, Sublessor and Master Lessor will allow Sublessee to have access to the building as soon as is reasonably practical to install telephone lines, network wiring and other Sublessee provided infrastructure as agreed by the parties. Any Sublessee contractors will coordinate with Sublessor's contractors and Master Lessor's General Contractor for the above work. Sublessee shall install their own voice/data cabling, as well as provide any 220 electrical requirements at their own expense. All such installation shall be subject to pre-approval by the Sublessor, which shall not be unreasonably withheld. 2.3 Upon expiration of the Term or upon early termination of the Sublease, Sublessee shall immediately surrender the Subleased Premises in good condition to the Sublessor, normal wear and tear excepted. In addition, upon surrender of the Subleased Premises, Sublessee shall remove any of its trade fixtures and all its personal property from the Subleased Premises. 2.4 If the Subleased Premises remain in the possession of the Sublessee with the consent of the Sublessor after the Term has expired, the Sublessee shall be deemed to be occupying the Subleased Premises on a month to month basis with a monthly rent equal to the last Rent amount in effect. Such month to month occupancy shall be subject to the terms of this Sublease, and be subject to termination upon 30 days' written notice by either party. 2.5 If the Subleased Premises remain in the Sublessee's possession after the expiration of the Term without the consent of the Sublessor, or after early termination of the Sublease, the Sublessee's occupancy shall be deemed tenancy at sufferance and Sublessee shall be liable for monthly rent in the amount of two times the last Rent in effect. 2.6 At the end of the Sublease Term, Sublessor shall determine whether Sublessor requires the Subleased Premises for its own use. If the Sublessor decides to sublease the Subleased Premises, the Sublessor shall negotiate in good faith with the Sublessee to extend the sublease term, provided the Sublessee has not defaulted under the Sublease and such default remains uncured. The Sublessor shall provide three (3) months notice of their intent. 3. Base Rent 3.1 Payment of rent shall be due and payable on the date of general occupancy. Rent shall be at the rate of $2.15 per rentable square foot. Sublessee shall pay to Sublessor without deduction, setoff, prior notice or demand, as rent for the Subleased Premises, equal monthly payments as shown below (hereinafter "Rent"): 4/1/99 to 3/31/01 $6,873.55 per month in advance on the first day of each month of the Term hereof. In the event the payment of Rent is not received by the Sublessor by the first day of each month, the Sublessor shall send written notice of non-receipt of the payment. Sublessee shall have a grace period of five (5) days after receipt of the written notice to pay the Rent. If Sublessee does not pay the Rent within five days after receipt of the written notice, Sublessee shall have defaulted under this Sublease and be subject to the provisions of section 7 of this Sublease. The above rent is based on rentable space of 3,197 square feet. If the date of general occupancy is not the first day of the month, or if the termination date is not the last day of the month, a pro rata portion of the monthly Rent shall be paid to the Sublessor at the then current rate for the fractional month during which the Sublease commences and/or terminates based on a 30-day month. Sublessee shall pay Sublessor on or before the occupancy date hereof the prorated sum due for the initial fractional month plus the sum due for the first full month of rent. 3.2 Services to the Subleased Premises shall be provided by the Master Lessor as per Article 6.00 of the Master Lease Agreement. Such services shall include heat, ventilation, cooling, janitorial services, electric power for normal lighting and small business office equipment (e.g. copiers, PC's, etc.), running water, and maintenance, repair and replacement as defined in the referenced Article of the Master Lease. Master Lessor covenants to furnish all those services to the Subleased Premises and to the Building agreed by Master Lessor to be provided pursuant to Article 6.0 of the Master Lease. 4. Security Deposit Sublessee shall deposit with Sublessor upon execution of this Sublease hereof the sum of $6,873.55 as security for Sublessee's faithful performance of Sublessee's obligations hereunder. If Sublessee fails to pay Rent or other charges due hereunder, or otherwise defaults with respect to any provision of this Sublease, and fails to commence a cure of such default within the time provided therefor in this Sublease, Sublessor may use, apply or retain all or any portion of said deposit for the payment of any Rent or other charge in default or for the payment of any other sum which Sublessor may become obligated by reason of Sublessee's default, or to compensate Sublessor for any loss or damage which Sublessor may suffer thereby. If Sublessor so uses or applies all or any portion of said deposit, Sublessee shall within ten (10) days after written demand therefore, deposit cash with Sublessor in an amount sufficient to restore said deposit to the full amount herein above stated, and Sublessee's failure to do so shall be a default under this Sublease, and Sublessor may at its option terminate this Sublease. Sublessor shall not be required to keep said deposit separate from its general accounts. If Sublessee performs all of Sublessee's obligations hereunder, said deposit, or so much thereof as has not theretofore been applied by Sublessor, shall be returned without payment of interest for its use to Sublessee within ten (10) days after the expiration of the Term hereof, or after Sublessee has vacated the Subleased Premises, whichever is later. -2- Sublessee's Security deposit shall not bear interest. 5.

Seq.), at the time that this Sublease is executed. If this warranty hereafter is found not to be true, Sublessor shall work with the Master Lessor to bring the Subleased Premises into compliance. Sublessee shall, at Sublessee's expense, comply promptly with all applicable statutes, ordinances, rules, regulations, orders, restrictions of record, and requirements in effect during the Term hereof regulating the use of the Subleased Premises, provided, however, that Sublessee shall not be required to expend any of its funds for capital improvements or changes related to the Americans with Disabilities Act. 5.3 Except for latent and undisclosed defects, Sublessee hereby accepts the Subleased Premises in their condition existing as of the commencement date of the Term hereof, subject to all applicable zoning, municipal, county and state laws, ordinances and regulations governing and regulating the use of Subleased Premises, and accepts this Sublease subject thereto. 5.4 Sublessee acknowledges that neither Sublessor nor Sublessor's agents have made any representation or warranty as to the suitability of the Subleased Premises for the conduct of the Sublessee's business. 5.5 Sublessee shall not assign or transfer the Sublease, or otherwise allow occupancy in whole or in part of the Subleased Premises by any other party without advance written consent from the Sublessor. 5.6 Sublessee shall keep the Subleased Premises in good condition. In the event the Sublessee fails to maintain the Subleased Premises, the Sublessor may, following no less than 48 hours' prior notice, enter the Subleased Premises, perform any needed repairs or maintenance, and charge the Sublessee for the cost incurred plus a 20% administrative fee.

Except with respect to any such Hazardous Materials used, generated, stored or disposed of, on or about the Subleased Premises by Sublessee, its employees, officers, directors, agents or contractors, Sublessor shall indemnify, defend, and hold Sublessee harmless from and against any and all liabilities, remediation costs, investigation costs, claims, damages, injuries, losses, costs, fines, judgments, causes of action and expenses whatsoever incurred in connection with or arising in any way out of the release, treatment, storage, use or disposal of Hazardous Materials on or about the Subleased Premises. -3- 6.

Sublessee shall not commit or permit to be committed on the Subleased Premises any act or omission which shall violate any term or condition of the Master Lease. 6.2 Sublessee shall hold Sublessor and Master Lessor harmless of and from all liability, judgements, costs, damages, claims or demands, including reasonable attorney's fees, arising out of Sublessee's failure to comply with or perform Sublessee's obligations under both the Master Lease and this Sublease, as such obligations apply to the Premises. 6.3 Sublessor represents to Sublessee that the Master Lease is in full force and effect and that no default exists on the part of any party to the Master Lease. 7. Default 7.1 Sublessee shall pay a penalty of 5% of the Rent amount due as a late fee in the event Rent payments are received by the Sublessor more than 10 days after the due date for the Rent.

Sublessee shall indemnify Sublessor and Master Lessor against all costs and charges (including legal fees) lawfully and reasonably incurred in enforcing payment of the Rent, and in obtaining possession of the Subleased Premises after default of the Sublessee or upon expiration or earlier termination of the Term of this sublease. 7.2 All covenants and agreements to be performed by the Sublessee under any of the terms of this Sublease shall be performed by the Sublessee at Sublessee's sole cost and expense, and without any abatement of Rent. If Sublessee fails to perform any act on its part to be performed hereunder, and such failure shall continue for 10 days after notice thereof from Sublessor, Sublessor may perform such act (but shall not be obligated to do so) without waiving or releasing Sublessee from any of its obligations relative thereto. All reasonable sums paid or costs incurred by Sublessor in so performing such acts together with interest thereon at the rate set in paragraph 7.1 herein from the date payment was made or each cost incurred by the Sublessor shall be payable by Sublessee to Sublessor on demand. 7.3 The following events shall be deemed events of default by Sublessee under this Sublease: (a) part or all of the Rent is not paid when due and Sublessee has not paid the Rent within five (5) days after receipt of a written notice from the Sublessor, or (b) Sublessee becomes insolvent or commits an act of bankruptcy or becomes bankrupt or takes benefit of any statute that may be in force for bankrupt or insolvent debtors or becomes involved in involuntary or involuntary winding-up proceedings or if a receiver is appointed for the business, property, affairs or revenues of Sublessee, or (c) Sublessee ceases to conduct business from the Subleased Premises, or (d) Sublessee fails to observe, perform, and keep each and every material covenant, agreement, provision, stipulation and condition herein contained to be observed, performed, and kept by Sublessee. 7.4 Upon the occurrence of any event of default by Sublessee, Sublessor shall have, in addition to other remedies available to Sublessor at law or in equity, the option to pursue any one or more of the following remedies (each and all of which shall be cumulative and non-exclusive) without any notice or demand whatsoever: (a) Terminate this Sublease, in which case Sublessee shall immediately surrender the Subleased Premises to Sublessor, and if Sublessee fails to do so, Sublessor may enter and take possession of the Subleased Premises and expel or remove the Sublessee and any other person who may be occupying the -4- Subleased Premises or any part thereof, without being liable for prosecution or any claim or damages therefore; and Sublessor may recover from Sublessee the following: (i) the worth at the time of award of any unpaid Rent which has been earned at the time of termination, plus (ii) the worth at the time of award of the amount by which the unpaid Rent which would have been earned after termination until the time of award exceeds the amount of such loss of Rent that Sublessee proves could have been reasonably avoided; plus (iii) the worth at the time of award by which the unpaid Rent for the balance of the Term after the time of award exceeds the amount of such loss of rent that Sublessee proves could have been reasonably avoided; plus (iv) any other amount necessary to compensate Sublessor for all the detriment proximately caused by Sublessee's failure to perform its obligations under this Sublease; and (v) at Sublessor's election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable law. (b) If Sublessor does not elect to terminate this Sublease on account of any default by Sublessee, Sublessor may, from time to time, without terminating this Sublease, enforce all of its rights and remedies under this Sublease, including the right to recover all Rent as it becomes due. (c) If the Sublessee defaults under this agreement, Sublessor shall have the right to terminate any and all subleases, licenses, concessions or other arrangements for possession entered into by Sublessee and affecting the Subleased Premises or may, in Sublessor's sole discretion, succeed to Sublessee's interest in such subleases, licenses, concessions or arrangements.
