          (a) Insurance on Buildings. Notwithstanding anything to the contrary

Paragraph 13(l) of the Restatement, Landlord shall maintain the insurance
described in clauses (a) and (d) of Section 15.2 of the Original Lease with
respect to each Premises and Building (including any Premises constituting only
a portion of an entire Building). Such insurance may be maintained as part of
Landlord's blanket property insurance. The actual cost of maintaining such
insurance with respect to each Building (appropriately allocated and segregated
in Landlord's reasonable determination if carried as part of Landlord's blanket
property coverage) shall be included in Total Operating Expenses for such
Building as to which Tenant shall pay, as additional rent, Tenant's
Proportionate Share thereof in accordance with the 


                                       3
<PAGE>   4
provisions of Exhibit "B" attached to the Original Lease, as amended by the
Restatement; provided, however, that in no event shall Tenant be responsible for
any portion of the cost of maintaining earthquake coverage or for the cost of
insurance coverage pursuant to clause (a) of Section 15.2 in excess of full
replacement cost as determined by Landlord in its sole, but reasonable
discretion; provided, further, that in no event shall the limitations on the
amount of Additional Rent payable by Tenant for the applicable Premises as
provided in Paragraph 7 of the Restatement apply with respect to any amount
included in Total Operating Expenses pursuant to this Paragraph 6. In other
words, Tenant shall pay its Proportionate Share of the cost of the insurance
specified herein, notwithstanding the limitations provided for in such Paragraph
7 of the Restatement. As used in such Section 15.2 of the Original Lease, the
term "All Risk" shall include fire insurance with an extended coverage
endorsement.

               (b) Tenant's Liability Insurance. The last sentence of Section
15.1(b) of the Original Lease, as amended by clause (i) of Paragraph 13(l) of
the Restatement, is hereby deleted. As a matter of clarification in the
Restatement, it is acknowledged and agreed that the phrases "second unnumbered
paragraph" and "last unnumbered paragraph" as used in Paragraph 13(l) of the
Restatement shall mean, respectively, "the paragraph appearing directly below
Section 15.1(b) of the Original Lease" and the "last full paragraph of Section
15.1 of the Original Lease."

               (c) Insurance Company Qualifications; Certificates of Insurance.
Section 15.3 of the Lease, as amended by clause (iii) of Paragraph 13(1) of the
Restatement, is hereby deleted in its entirety and replaced with the following:

               "15.3 All insurance required to be carried by Landlord or Tenant
     shall be with companies rated A:VII or better in the then most recent
     version of Best's Insurance Guide. Tenant shall use reasonable efforts to
     deliver to Landlord at least ten (10) days prior to the expiration or
     renewal date of any policy of insurance required to be maintained by Tenant
     hereunder, but in any event prior to the lapse of coverage under any such
     policy, copies of the policies or certificates evidencing such insurance.
     At the written request of Tenant, Landlord shall provide to Tenant a copy
     of the certificate evidencing the insurance required to be maintained by
     Landlord hereunder. All policies and certificates maintained and delivered,
     as applicable, pursuant to this Article shall contain liability limits not
     less than those set forth herein, shall list the additional insureds and
     shall specify all endorsements and special coverages required. Each policy
     of insurance required to be maintained by Tenant hereunder shall contain a
     provision requiring not less than thirty (30) days' written notice to
     Landlord prior to any cancellation, non-renewal or material amendment
     thereof. For the purposes of this Article, "term" and "term of this Lease"
     shall mean the period from the Commencement Date through the later of the
     expiration or termination of the Lease term or the date Tenant surrenders
     possession of the Premises to Landlord. All policies of insurance required
     to be carried hereunder shall be primary, and shall not contain a
     co-insurance or contribution provision. For purposes of Section 15.3 of the
     Lease, if the rating of any of Landlord's or Tenant's insurance carriers on
     any insurance policy(ies) required to be maintained under the Lease drops
     below A:VII, the party maintaining such insurance shall not be required to
     replace such insurance carrier until the renewal date of the policy(ies),
     unless such rating drops below B:VII, in which event such insurance carrier
     shall be replaced with a carrier meeting the A:VII rating requirement
     within ninety (90) days after the occurrence thereof."

               (d) Landlord's Liability Insurance. Section 15.4 of the Lease is
hereby deleted in its entirety and replaced with the following:

          "15.4 Landlord shall at all times during the term maintain in full
     force and effect a policy or policies of commercial general liability
     insurance insuring against loss, damage or liability for injury to or death
     of any person or loss or 


                                       4
<PAGE>   5
     damage to property occurring in the Common Facilities (as defined in
     Exhibit "B" hereto) or in the public areas of the Building, with not less
     than $2,000,000.00 combined single limit for both bodily injury and
     property damage, including contractual liability (including Landlord's
     indemnification obligations under this Lease). The liability insurance
     required to be carried by Landlord hereunder shall be on an occurrence (as
     opposed to claims made) basis. Landlord may at any time and from time to
     time increase such insurance limits to a level which Landlord reasonably
     deems necessary for its full and adequate protection. Landlord shall also
     at all times during the term maintain in full force and effect a policy or
     policies of fire insurance with an extended coverage endorsement with
     respect to the Common Facilities, and Landlord may maintain such other
     coverage endorsements, including, but not limited to "All Risk," vandalism
     and earthquake insurance, as Landlord deems necessary or advisable with
     respect thereto. The actual cost of all insurance obtained by Landlord
     hereunder shall be included in Total Operating Expenses (as defined in
     Exhibit "B" hereto)."

               (e) Damage or Destruction. The first sentence of clause (ii)(A)
of Paragraph 13(n) of the Restatement is hereby amended to read as follows:

               "In the event such Premises, access to them, or the Parking Areas
     or driveway serving such Premises are wholly or partially destroyed by fire
     or other casualty covered by the insurance required to be maintained by
     Landlord under the terms of the Lease, as hereby amended, or any insurance
     coverage actually carried by Landlord with respect thereto, Landlord shall
     rebuild, repair or restore the Premises and access thereto to substantially
     the same condition as when the same were furnished to Tenant, excluding any
     improvements installed therein by Tenant and Tenant's personal property,
     and the Lease, as hereby amended, will continue in full force and effect
     with respect to such Premises."

               (f) Tenant's Option to Maintain Insurance. Notwithstanding
anything to the contrary in this Paragraph 6, so long as Tenant is not in
default (i.e., after any applicable notice and cure period) under the Lease, as
hereby amended, Tenant shall have the option at any time during the term of the
Lease to maintain the insurance described in clauses (a) and (d) of Section 15.2
of the Original Lease. Such option shall be exercised, if at all, upon not less
than sixty (60) days' prior written notice to Landlord stating, in substance,
that Tenant is electing to maintain such insurance. In the event that Tenant
shall be entitled to exercise such option and shall do so in such manner, then
from and after the sixtieth (60th) day following the effective date of Tenant's
notice to Landlord through the expiration of the term, (i) Tenant shall, at its
sole cost and expense, maintain such insurance and (ii) the provisions of
subparagraphs (a), (c), (d) and (e) of this Paragraph 6 shall have no further
force or application with respect to the Lease, as hereby amended. In addition,
Tenant shall not be responsible for any portion of the cost of the insurance
incurred by Landlord pursuant to subparagraph (a) above for any period
subsequent to the sixtieth (60th) day following the effective date of Tenant's
notice to Landlord.

     7.   Effective Date of Paragraphs. The amendments to the Lease provided for
in Paragraphs 6(a) through (e) hereof shall be effective as of December 1, 1995,
notwithstanding the later execution and delivery hereof by Landlord and Tenant.

     8.   Defined Terms. Any term used in this Amendment and not otherwise 
defined herein shall have the meaning assigned to such term in the Lease.

     9.   Lease in Effect. Landlord and Tenant acknowledge and agree that the
Lease, as hereby amended, remains in full force and effect in accordance with
its terms. In the event of any conflict between the terms of this Amendment and
the terms of the Original Lease and/or the Restatement, the terms of this
Amendment shall control.
