The Old Lease is attached. Landlord and Tenant have agreed to lease a portion of the real property on all the terms set forth in the Old Lease except as set forth below (the "Lease").

During the term, Landlord also authorizes the use of the common areas appurtenant to the Premises and defined as the "Outside Area" in Section 11 below and the use of the personal property on the Premises identified in Exhibit E according to Exhibit E.

There is no change to this Section. 25. ASSIGNMENT. This Section is replaced with the following: "Because of the unique nature of the larger transaction among Landlord, Tenant and Cigna and the bargain element of the Lease, under no circumstances will Tenant be allowed to assign this Lease or sublease any portion of the Premises, except to an "Affiliate" after ten days' notice to Landlord. An "Affiliate" for purposes of this Section is a wholly owned subsidiary of Tenant as well as UMAX Computer Corp. and Splash Technology, Inc., which corporations were occupants of the Premises upon the termination of the Old Lease, provided that (i) each such Affiliate agrees to be bound by the provisions of this Lease, (ii) UMAX Computer Corp. vacates the Premises by April 15, 1996 and (iii) Splash Technology, Inc. vacates the Premises within 90 days after the Commencement Date. Also, in the event Tenant desires to assign this Lease to the survivor of any merger with a third party, Tenant will seek Landlord's approval prior to the merger and Landlord will not 3 unreasonably withhold or delay its consent. However, Landlord can elect to expand into the Premises and terminate the lease as of the effective date of the merger by so notifying Tenant, unless the survivor agrees to increase the Monthly Installment by 150% and promptly notifies Landlord of such election. Any other attempt to assign or sublease will be null and void at Landlord's election. In the case of any other effective assignment or sublease, Landlord will have the right of first refusal to lease the space on the same terms and the right to one half of the net proceeds of any such assignment or sublease. Despite any assignment or sublease, Tenant will remain liable for the performance of all tenant obligations under this Lease." 26-31. There are no changes to these Sections. 32. PARKING. Add at the end of the first sentence: "and is consistent with Landlord's general signage plan which Landlord may establish in its discretion." It is understood that the two large exterior "Radius" signs at two corners of the Building will be replaced by Landlord at its expense with its own signage. Tenant's signage will include a monument at the entrance to the parking lot and one other directional sign referring to the location of the Radius lobby. 33-36. There are no changes to these Sections. 37. BROKERS. The references to CPS Commercial Brokerage and Cornish & Carey Commercial Real Estate are deleted. 38. There is no change to this Section. 39. Section 39D is amended as follows: the clause "occurring during the Lease Term (including any extensions thereof)" in the final two lines of the first paragraph is replaced with "occurring during Tenant's use or occupancy of any portion of the Complex". 40-42. These Sections are deleted. In witness whereof, the parties execute this Lease. Landlord: Integrated Systems, Inc. Tenant: Radius Inc. _______________________________ ______________________________ By: date By: date (List of exhibits) Exhibit A -- the Premises (replaced with a new Exhibit A) Exhibit B -- the real property legal description (no change) Exhibit C -- the Improvements (replaced with a new Exhibit C) Exhibit D -- Truck parking area (no change) Exhibit E -- Personal Property use (replaced with a new Exhibit E) Exhibit F -- Complex landscaping (no change) 4 EXHIBIT "C" IMPROVEMENTS Exhibit C to the Old Lease is replaced with the following new Exhibit C. Landlord and Tenant have agreed on the improvements to be constructed on or about the Premises. These improvements are set forth in the attached final plans and specifications (the "Improvements"). Landlord will bear the cost of the Improvements except for $0 (or the costs associated with a specific scope of work identified on Schedule C-1, if applicable) ("Tenant's Share"). Prior to and after the Commencement Date, Tenant will consolidate within the Premises as reasonably required by Landlord to permit the construction work to be performed expeditiously and to permit Landlord to occupy the balance of the Building in stages between March 18, 1996 and April 30, 1996 as described in the attached plans. Promptly after the Commencement Date, Landlord will retain a general contractor to construct the Improvements. Landlord will direct the general contractor to construct the Improvements as quickly as the work can be performed in a commercially reasonable manner by no later than April 30, 1996. There may be some disruption to Tenant's use of the Premises during construction, and Tenant will reasonably cooperate with the general contractor and its subcontractors in facilitating the performance of the work. Tenant will not attempt to withhold or delay any payment nor seek compensation as a result of any of these inconveniences. No changes in the scope of work for the Premises will be made without Landlord's and Tenant's prior written approval. Otherwise, changes in the plans and specifications will be made only to accommodate the reasonable requests of the permitting authorities. If Tenant requests a change that either delays completion or increases costs and the change is approved, the related costs be shall added to Tenant's Share. Upon substantial completion of the Improvements, Landlord will so notify Tenant and the parties will schedule a walk through with the general contractor or construction manager. If reasonably satisfied, Tenant will promptly sign an acceptance of the Improvements, subject only to the performance of any "punch list" items, which do not materially impair the use of the final Premises. Upon such acceptance, Tenant will tender payment of Tenant's Share to Landlord. Tenant's unreasonable refusal to promptly accept the Improvements or to relocate on a timely basis will be a material breach of this Lease, if Landlord is thereby prevented from occupying the remainder of the Building by between March 18, 1996 and April 30, 1996 according to the schedule attached to the plans referred to above. In such event and in addition to the remedies identified in Section 15 of the Lease, because actual damages are impractical to calculate and because of the obvious bargain element in the regular rental rate, the Monthly Installment will automatically increase by 150% until the breach has been cured to Landlord's reasonable satisfaction, provided that Tenant has had a reasonable opportunity to cure the breach prior to the increase. 5 EXHIBIT "E" LICENSE TO USE CERTAIN PERSONAL PROPERTY Exhibit E to the Old Lease is replaced with the following new Exhibit E. During the term, Tenant is authorized to use the personal property identified on Schedule 0 on an exclusive basis. Tenant will relocate such property at its own expense prior to the Commencement Date to the Premises depicted on Exhibit A. Tenant will use reasonable care in the use and relocation of such property and will return such property to Landlord in good condition, normal wear and tear excepted, upon termination of the Lease. During the term, Tenant is also authorized to use the personal property identified on Schedule 0 on a shared or nonexclusive basis (e.g., the existing telephone system). All items of personal property will be clearly marked by Tenant as Landlord's property throughout such period of use. Tenant will promptly notify Landlord if the property requires repair, which will be the responsibility of Landlord, unless the repair is necessitated by Tenant's (including employees, visitors and agents) gross negligence or intentional misconduct. Landlord is also responsible for insuring the property and paying related real and personal property taxes accruing after Landlord takes title to such property. Landlord will have no obligation to replace any item, unless its cost is fully covered by insurance. Tenant agrees to execute such other documents or perform such other acts as may be reasonably be necessary in Landlord's discretion to ensure that Landlord's title to such property remains unimpaired by creditors or representatives of Tenant, e.g., filing financing statements. Under no circumstances will Tenant challenge Landlord's ownership of the personal property or attempt to offset the value of the personal property against any obligation owed to Landlord during or after the term. During the term, Landlord will continue to operate the cafeteria through a subcontractor and Tenant will be authorized to use the cafeteria subject to Landlord's and the subcontractor's reasonable rules and regulations. The cafeteria will not be obligated to provide services other than lunch Monday through Friday. In the event of a material breach of this Lease by Tenant, including the failure to pay a Monthly Installment or Additional Rent, Tenant's rights to use the personal property and the cafeteria without additional charge will be automatically suspended after Tenant has had a reasonable opportunity to cure such breach until the breach is cured to Landlord's reasonable satisfaction. 6
