AMOROSO ---------------------------- Name: Alfred J. Amoroso ---------------------------- Title: President & CEO ---------------------------- By: ---------------------------- Name: ---------------------------- Title: ---------------------------- EXHIBIT B-2 -2- EXHIBIT B-3 ----------- WORK LETTER ----------- (Maximum Amount: Plans Not Yet Completed) ----------------------------------------- This Exhibit is attached to and made a part of the Lease dated the 15th day of August, 2000, by and between EOP-BAY PARK PLAZA, L.L.C., a Delaware limited liability company ("Landlord") and CROSSWORLDS SOFTWARE, INC., a Delaware corporation ("Tenant") for space in the Building located at 577 Airport Boulevard, Burlingame, California. 1. This Work Letter shall set forth the obligations of Landlord and Tenant with respect to the preparation of the Eighth Expansion Space for Tenant's occupancy. All improvements described in this Work Letter to be constructed in and upon the Eighth Expansion Space by Landlord are hereinafter referred to as the "Eighth Expansion Space Landlord Work." It is agreed that construction of the Eighth Expansion Space Landlord Work is intended to be "turn-key" and will be completed at Landlord's sole cost and expense, using Building Standard methods, materials, and finishes. Notwithstanding the foregoing, Landlord and Tenant acknowledge that the Eighth Expansion Plans (hereinafter defined) for the Eighth Expansion Space Landlord Work have not yet been prepared, and, therefore, it is impossible to determine the exact cost of the Eighth Expansion Space Landlord Work at this time. Accordingly, Landlord and Tenant agree that Landlord's obligation to pay for the cost of Eighth Expansion Space Landlord Work (inclusive of the cost of preparing Eighth Expansion Plans, obtaining permits, a construction management fee equal to 5% of the total construction costs, and other related costs) shall be limited to $62,020.00 (the "Maximum Amount") and that Tenant shall be responsible for the cost of Eighth Expansion Space Landlord Work, plus any applicable state sales or use tax, if any, to the extent that it exceeds the Maximum Amount. Landlord shall enter into a direct contract for the Eighth Expansion Space Landlord Work with Commercial Interior Contractors. Landlord shall have the right to select and/or approve of any subcontractors used in connection with the Eighth Expansion Space Landlord Work. 2. Tenant shall be solely responsible for the timely preparation and submission to Landlord of the final architectural, electrical and mechanical construction drawings, plans and specifications (called "Eighth Expansion Plans") necessary to construct the Eighth Expansion Space Landlord Work, which plans shall be subject to approval by Landlord and Landlord's architect and engineers and shall comply with their requirements to avoid aesthetic or other conflicts with the design and function of the balance of the Building. Tenant shall be responsible for all elements of the design of Tenant's plans (including, without limitation, compliance with law, functionality of design, the structural integrity of the design, the configuration of the premises and the placement of Tenant's furniture, appliances and equipment), and Landlord's approval of Tenant's plans shall in no event relieve Tenant of the responsibility for such design. If requested by Tenant, Landlord's architect will prepare the Eighth Expansion Plans necessary for such construction at Tenant's cost. Whether or not the layout and Eighth Expansion Plans are prepared with the help (in whole or in part) of Landlord's architect, Tenant agrees to remain solely responsible for the timely preparation and submission of the Eighth Expansion Plans and for all elements of the design of such Eighth Expansion Plans and for all costs related thereto. Tenant has assured itself by direct communication with the architect and engineers (Landlord's or its own, as the case may be) that the final approved Eighth Expansion Plans can be delivered to Landlord on or before October 2, 2000 (the "Eighth Expansion Plans Due Date"), provided that Tenant promptly furnishes complete information concerning its requirements to said architect and engineers as and when requested by them. Tenant covenants and agrees to cause said final, approved Eighth Expansion Plans to be delivered to Landlord on or before said Eighth Expansion Plans Due Date and to devote such time as may be necessary in consultation with said architect and engineers to enable them to complete and submit the Eighth Expansion Plans within the required time limit. Time is of the essence in respect of preparation and submission of Eighth Expansion Plans by Tenant, (The word "architect" as used in this Exhibit B-3 shall include an interior designer or space planner.) 3. In the event Landlord's estimate and/or the actual cost of the Eighth Expansion Space Landlord Work shall exceed the Maximum Amount, Landlord, prior to commencing any construction of Eighth Expansion Space Landlord Work, shall submit to Tenant a written estimate setting forth the anticipated cost of the Eighth Expansion Space Landlord Work, including but not limited to labor and materials, contractor's fees and permit fees. EXHIBIT B-3 -1- Within three (3) Business Days thereafter, Tenant shall either notify Landlord in writing of its approval of the cost estimate, or specify its objections thereto and any desired changes to the proposed Eighth Expansion Space Landlord Work. In the event Tenant notifies Landlord of such objections and desired changes, Tenant shall work with Landlord to reach a mutually acceptable alternative cost estimate. 4. In the event Landlord's estimate and/or the actual cost of construction shall exceed the Maximum Amount (such amounts exceeding the Maximum Amount being herein referred to as the "Eighth Expansion Excess Costs"), Tenant shall pay to Landlord such Eighth Expansion Excess Costs, plus any applicable state sales or use tax thereon, upon demand. The statements of costs submitted to Landlord by Landlord's contractors shall be conclusive for purposes of determining the actual cost of the items described therein. The amounts payable by Tenant hereunder constitute Rent payable pursuant to the Lease, and the failure to timely pay same constitutes an event of default under the Lease. 5. If Tenant shall request any change, addition or alteration in any of the Eighth Expansion Plans after approval by Landlord, Landlord shall have such revisions to the drawings prepared, and Tenant shall reimburse Landlord for the cost thereof, plus any applicable state sales or use tax thereon, upon demand to the extent that the cost of performing such revisions cause the cost of Eighth Expansion Space Landlord Work to exceed the Maximum Amount. Promptly upon completion of the revisions, Landlord shall notify Tenant in writing of the increased cost, if any, which will be chargeable to Tenant by reason of such change, addition or deletion. Tenant, within one (1) Business Day, shall notify Landlord, in writing, whether it desires to proceed with such change, addition or deletion. In the absence of such written authorization, Landlord shall have the option to continue work on the Eighth Expansion Space disregarding the requested change, addition or alteration, or Landlord may elect to discontinue work on the Eighth Expansion Space until it receives notice of Tenant's decision, in which event Tenant shall be responsible for any delay in completion of the Eighth Expansion Space resulting therefrom. In the event such revisions result in a higher estimate of the cost of construction and/or higher actual construction costs which exceed the Maximum Amount, such increased estimate or costs shall be deemed Eighth Expansion Excess Costs pursuant to Paragraph 4 hereof and Tenant shall pay such Eighth Expansion Excess Costs, plus any applicable state sales or use tax thereon, upon demand. 6. Following approval of the Eighth Expansion Plans and the payment by Tenant of the required portion of the Eighth Expansion Excess Costs, if any, Landlord will cause the Eighth Expansion Space Landlord Work to be constructed substantially in accordance with the approved Eighth Expansion Plans. Landlord shall notify Tenant of substantial completion of the Eighth Expansion Space Landlord Work. 7. This Exhibit B-3 shall not be deemed applicable to any additional space added to the Premises (including, without limitation, the Eighth Expansion Space) at any time or from time to time, whether by any options under the Lease or otherwise, or to any portion of the Premises (including, without limitation, the Eighth Expansion Space) or any additions to Premises (including, without limitation, the Eighth Expansion Space) in the event of a renewal or extension of the original Term of this Lease, whether by any options under the Lease or otherwise, unless expressly so provided in the Lease or any amendment or supplement to the Lease.
