The term (the "Term") of this Sublease shall be for the ---- period commencing on October 1, 1999 (the "Commencement Date") and ending on September 30, 2002 (the "Expiration Date"), unless this Sublease is sooner terminated pursuant to its terms or the Lease is sooner terminated pursuant to its terms. The Commencement Date shall be delayed by one (1) day for each day the consent of Master Lessor and Lessor to the Sublessee Improvements (substantially as described in the plans submitted by CAS Architects to Lessor) is delayed after August 30, 1999; provided, however, that in the event Master Lessor or Lessor reasonably request additional information to evaluate the Sublessee Improvements, Sublessee shall supply such requested information within a reasonable period, and there shall be no further delay in the Commencement Date as a result of Sublessee's delay beyond such reasonable period. B. Early Possession. Sublessor shall permit Sublessee to enter the ---------------- Subleased Premises upon execution of this Sublease and receipt of consent hereto by Lessor and Master Lessor solely for the purposes of constructing the Sublessee Improvements (as defined in Section 11 below) in the Subleased Premises and installing therein its fixtures, furniture and cabling.

Any such alterations shall be performed in compliance with all laws and with the provisions of Section 11 hereof. C. Sublessor Direct Lease with Master Lessor. The parties hereby ----------------------------------------- acknowledge that Sublessor has entered into or plans to enter into a direct lease with Master Lessor for the Premises to commence upon the termination of the Lease (the "Direct Lease").

This Sublease and Sublessor's obligations hereunder are further conditioned upon Sublessee having obtained the consent of Master Lessor, Lessor and Sublessor to the Sublessee Improvements, as described on Schedule 1 attached hereto and incorporated by reference herein. 22. Authority to Execute: Sublessee and Sublessor each represent and -------------------- warrant to the other that each person executing this Sublease on behalf of each party is duly authorized to execute and deliver this Sublease on behalf of that party. 23. Extension Option. ---------------- A. Subject and subordinate to Sublessor's business needs and at Sublessor's sole and absolute discretion, Sublessor, not later than September 30, 2001, shall notify Sublessee whether Sublessor will permit Sublessee to extend the Term of this Sublease for an additional term of two (2) years ("Extension Term"). Sublessor's failure to deliver such a notice shall be deemed Sublessor's refusal to permit Sublessee to extend the Term of this Sublease. If Sublessor notifies Sublessee that it is willing to permit Sublessee to extend the Term of this Sublease as described above, provided a monetary default (after expiration of applicable notice and cure periods) has not occurred hereunder, Sublessee may exercise the option to extend (the "Option") not later than two hundred seventy (270) days prior to the Expiration Date. Base Rent for the Extension Term shall be the then-fair market rent for the Subleased Premises ("FMR") as of the commencement of the Extension Term, including rental increases, if applicable, as agreed upon by Sublessor and Sublessee, or, if the parties cannot agree within sixty (60) days prior to the commencement of the -8- Extension Term, as established pursuant to arbitration as described below. In no event shall Base Rent for the Extension Term be less than Two Dollars and 55/100 ($2.55) per rentable square foot of the Subleased Premises. All other terms and conditions of this Sublease shall apply during the Extension Term, except that Sublessee shall have no further option to extend the Term. B. If it becomes necessary to determine the FMR by appraisal, real estate appraiser(s), all of whom shall be Members of the Appraisal Institute and who have at least five (5) years experience appraising comparable space located in the vicinity of the Subleased Premises shall be appointed and shall act in accordance with the following procedures: (i) If the parties are unable to agree on the FMR within the allowed time, either party may demand an appraisal by giving written notice to the other party, which demand to be effective must state the name, address and qualifications of an appraiser selected by the party demanding an appraisal (the "Notifying Party"). Within ten (10) days following the Notifying Party's appraisal demand, the other party (the "Non-Notifying Party") shall either approve the appraiser selected by the Notifying Party or select a second properly qualified appraiser by giving written notice of the name, address and qualification of such appraiser to the Notifying Party. If the Non-Notifying Party fails to select an appraiser within the ten (10) day period, the appraiser selected by the Notifying Party shall be deemed selected by both parties and no other appraiser shall be selected. If two appraisers are selected, they shall select a third appropriately qualified appraiser. If the two appraisers fail to select a third qualified appraiser, the third appraiser shall be appointed by the then presiding judge of the county where the Premises are located upon application by either party. (ii) If only one appraiser is selected, that appraiser shall notify the parties in simple letter form of its determination of the FMR within fifteen (15) days following his selection, which appraisal shall be conclusively determinative and binding on the parties as the appraised FMR. If multiple appraisers are selected, the appraisers shall meet not later than ten (10) days following the selection of the last appraiser. At such meeting the appraisers shall attempt to determine the FMR as of the commencement date of the Extension Term as described above by the agreement of at least two (2) of the appraisers. If two (2) or more of the appraisers agree on the FMR at the initial meeting, such agreement shall be determinative and binding upon the parties hereto and the agreeing appraisers shall, in simple letter form executed by the agreeing appraisers, forthwith notify both Sublessor and Sublessee of the amount set by such agreement. If multiple appraisers are selected and two (2) appraisers are unable to agree on the FMR, all appraisers shall submit to Sublessor and Sublessee an independent appraisal of the FMR in simple letter form within twenty (20) days following appointment of the final appraiser. The parties shall then determine the FMR by averaging the appraisals; provided that any high or low appraisal, differing from the middle appraisal by more than ten percent (10%) of the middle appraisal, shall be disregarded in calculating the average. (iii) If only one appraiser is selected, then each party shall pay one-half of the fees and expenses of that appraiser. If three appraisers are selected, each party shall bear the fees and expenses of the appraiser it selects and one-half of the fees and expenses of the third appraiser. C. The parties hereby acknowledge that the Extension Term, as described herein, extends beyond the term of the Lease. In the event that Sublessor does not enter into the Direct Lease or that the Direct Lease does not commence for any reason whatsoever, the Extension Term shall be automatically shortened to terminate upon the termination of the Lease. In the event that Sublessee properly exercises the Option and the Direct Lease commences, the Sublease shall continue as a sublease under the Direct Lease as described in Section 3.C hereof and Sublessee shall have the termination right described in Section 3.C hereof. -9- D. The Option is personal to Synplicity, Inc. or any Corporate Affiliate and may not be exercised following an assignment of this Sublease or a sublease of all or any portion of the Subleased Premises. 24. Sublessor's Indemnification. If this Sublease is terminated solely as --------------------------- a result of a default by Sublessor under this Sublease, the Lease or the Master Lease (which default is not due in any manner to Sublessee or other subtenants), Sublessor shall indemnify, protect, defend with counsel reasonably acceptable to Sublessee and hold Sublessee harmless from and against any and all claims, liabilities, judgments, causes of action, damages, costs and expenses (including reasonable attorneys' and experts' fees), caused by or arising in connection with Sublessor's default and resultant termination of this Sublease. 25. No Voluntary Termination. Sublessor shall not voluntarily terminate ------------------------ the Lease as to the Subleased Premises during the Term without Sublessee's prior written consent, which consent may not be unreasonably withheld or delayed, unless and until Lessor has agreed in writing to continue this Sublease in full force and effect as a direct lease between Lessor and Sublessee upon and subject to all of the terms, covenants and conditions of this Sublease for the balance of the Term hereof. If Lessor so consents, Sublessee shall attorn to Lessor in connection with any such voluntary termination and shall execute an attornment agreement in such form as may reasonably be requested by Lessor; provided, however, that the attornment agreement does not materially adversely affect the use by Sublessee of the Subleased Premises in accordance with the terms of this Sublease, materially increase Sublessee's obligations under this Sublease or materially decrease Sublessee's rights under this Sublease. 26. No Amendment. Sublessor and Lessor shall not amend or modify the ------------ Lease in any way so as to materially or adversely affect Sublessee or its interests hereunder, materially increase Sublessee's obligations hereunder or materially restrict Sublessee's rights hereunder, without the prior written consent of Sublessee, which may be withheld in Sublessee's sole but reasonable discretion. 27. Attorneys' Fees. If either Sublessor or Sublessee shall bring any --------------- action or legal proceeding to enforce, protect or establish any term or covenant of this Sublease, the prevailing party shall be entitled to recover its reasonable attorneys' fees, court costs and experts' fees as may be fixed by the court. "Prevailing party" as used in this Sublease includes a party who dismisses an action for recovery hereunder in exchange for sums allegedly due, performance of covenants allegedly breached or consideration substantially equal to the relief sought in the action. 28. Surrender. Notwithstanding anything to the contrary contained in this --------- Sublease, the Lease or the Master Lease, upon the expiration or earlier termination of this Sublease, Sublessee shall not be obligated to remove any alterations, additions or improvements made to the Premises by Sublessor, Lessor or any predecessor in interest to either of them prior to the date that Sublessee occupies the Subleased Premises for the purpose of constructing the Sublessee Improvements. 29. Counterparts. This Sublease may be executed in counterparts, each of ------------ which, when taken together as a whole, shall be deemed to constitute an original. A signed counterpart delivered by facsimile shall be deemed an original hereunder. 30. Sublessor's Representations and Warranties. Sublessor represents and ------------------------------------------ warrants with respect to the Subleased Premises that (a) the Lease and, to Sublessor's actual knowledge, without inquiry, the Master Lease, are in full force and effect, and there exists under Lease or, to Sublessor's actual knowledge, without inquiry, the Master Lease no event of default by either Master Lessor, Lessor or Sublessor; and (b) the copies of the Lease and, to Sublessor's actual knowledge, without inquiry, the Master Lease attached -10- hereto are true and complete copies of the Lease and Master Lease, and the Lease and, to Sublessor's actual knowledge, without inquiry, the Master Lease, have not been amended except as set forth therein. 31. Hazardous Substances. Sublessor hereby releases Sublessee with -------------------- respect to any losses, costs, claims, liabilities or damages due to the presence of Hazardous Substances on or about the Premises except to the extent due to the use, storage, release, discharge, emission or disposal of any Hazardous Substance on or about the Premises by Sublessee. IN WITNESS WHEREOF, the parties have executed this Sublease as of the day and year first above written.
