the Existing Premises, except those obligations of Tenant set forth in the 
Lease, as amended hereby, which specifically survive the expiration or earlier

          of hazardous material (as defined under applicable law) which was in
          existence in the Building or on the Project prior to the Lease
          Commencement Date, and was of such a nature that a federal, State or
          municipal governmental authority, if it had then had knowledge of the
          presence of such hazardous material, in the state, and under the
          conditions that it then existed in the Building or on the Project,
          would have then required the removal of such hazardous material or
          other remedial or containment action with respect thereto; and costs
          incurred to remove, remedy, contain, or treat hazardous material,
          which hazardous material is brought into the Building or onto the
          Project after the date hereof by Landlord or any other tenant of the

          or municipal governmental authority, if it had then had knowledge of
          the presence of such hazardous material, in the state, and under the
          conditions, that it then exists in the Building or on the Project,
          would have then required the removal of such hazardous material or

               If Landlord is not furnishing any particular work or service (the
          cost of which, if performed by Landlord, would be included in
          Operating Expenses) to a tenant who has undertaken to perform such
          work or service in lieu of the performance thereof by Landlord,
          Operating Expenses shall be deemed to be increased by an amount equal
          to the additional Operating Expenses which would reasonably have been
          incurred during such period by Landlord if it had at its own expense
          furnished such work or service to such tenant. If the Project is not
          at least ninety-five percent (95%) occupied during all or a portion of
          the Base Year or any Expense Year, Landlord shall make an appropriate
          adjustment to the components of Operating Expenses for such year to
          determine the amount of Operating Expenses that would have been
          incurred had the Project been ninety-five percent (95%) occupied; and
          the amount so determined shall be deemed to have been the amount of
          Operating Expenses for such year. Operating Expenses for the Base Year
          shall not include market-wide labor-rate increases due to
          extraordinary circumstances, including, but not limited to, boycotts
          and strikes, and utility rate increases due to extraordinary
          circumstances including, but not limited to, conservation surcharges,
          boycotts, embargoes or other shortages, or amortized costs relating to
          capital improvements."

to the calculation of Tenant's Share of annual Building Direct Expenses under

                              ------------------

     This Tenant Work Letter shall set forth the terms and conditions relating
to the construction of the tenant improvements in the New Premises. This Tenant
Work Letter is essentially organized chronologically and addresses the issues of
the construction of the New Premises, in sequence, as such issues will arise
during the actual construction of the New Premises. All references in this
Tenant Work Letter to Articles or Sections of "this First Amendment" shall mean
the relevant portion of Sections 1 through 11 of the First Amendment to Office
Lease to which this Tenant Work Letter is attached as Exhibit B-1 and of which
this Tenant Work Letter forms a part, and all references in this Tenant Work
Letter to Sections of "this Tenant Work Letter" shall mean the relevant portion
of Sections 1 through 6 of this Tenant Work Letter.

                                   SECTION 1

                  ------------------------------------------
                    
     Landlord shall construct the improvements in the New Premises (the "Tenant
Improvements") pursuant to those certain construction drawings entitled "Scheme
B", dated October 20, 1996, prepared by P. Patrick Murray (collectively, the
"Approved Working Drawings"). Tenant shall make no changes or modifications to
the Approved Working Drawings without the prior written consent of Landlord,
which consent may be withheld in Landlord's sole discretion if such change or
modification would directly or indirectly delay the "Substantial Completion," as
that term is defined in Section 5.1 of this Tenant Work Letter, of the New
Premises or increase the cost of designing or constructing the Tenant
Improvements.

                             ---------------------

     In the event that after Tenant's execution of this Lease, any revisions, 
changes, or substitutions shall be made to the Approved Working Drawings or the
Tenant Improvements, any additional costs which arise in connection with such
revisions, changes or substitutions shall be paid by Tenant to Landlord
immediately upon Landlord's request as an over-allowance amount (the "Over-
Allowance Amount"). The Over-Allowance Amount shall be disbursed by Landlord
prior to the disbursement of any portion of Landlord's contribution to the
construction of the Tenant Improvement.

                                   SECTION 3
                                   ---------

                    CONTRACTOR'S WARRANTIES AND GUARANTIES
                    --------------------------------------

     Landlord hereby assigns to Tenant all Warranties and guaranties by the 
contractor who constructs the Tenant Improvements (the "Contractor") relating 
to the Tenant Improvements, and Tenant hereby waives all claims against Landlord
relating to, or arising out of the construction of, the Tenant Improvements. 

                                   SECTION 4
                                   ---------

                               -----------------

                        NEW PREMISES COMMENCEMENT DATE
                        ------------------------------

     5.1  Ready for Occupancy.  The New Premises shall be deemed "Ready for 
          -------------------
Occupancy" upon the Substantial Completion of the New Premises. For purposes of 
this First Amendment, "Substantial Completion" of the New Premises shall occur 
upon the completion of construction of the Tenant Improvements in the New 
Premises pursuant to the Approved Working Drawings, with the exception of any 
punch list items and any tenant fixtures, work-stations, built-in furniture, or 
equipment to be installed by Tenant or under the supervision of Contractor.

     5.2  Delay of the Substantial Completion of the New Premises.  Except as 
          -------------------------------------------------------
provided in this Section 5.2, the New Premises Commencement Date shall occur as 
set forth in Section 3.1 of the First Amendment and Section 5.1, above. If there
shall be a delay or there are delays in the Substantial Completion of the New 
Premises or in the occurrence of any of the other conditions precedent to the 
New Premises Commencement Date, as set forth in Section 3.1 of the First 
Amendment, as direct, indirect, partial, or total result of:

          5.2.1  Tenant's failure to timely approve any matter requiring
Tenant's approval;

          5.2.2  A breach by Tenant of the terms of this Tenant Work Letter, the
Lease or this First Amendment;

          5.2.3  Tenant's request for changes in the Approved Working Drawings;

          5.2.4  Changes in any of the Approved Working Drawings because the
same do not comply with applicable laws;

          5.2.5  Tenant's requirement for materials, components, finishes or
improvements which are not available in a commercially reasonable time given the
anticipated date of Substantial Completion of the New Premises, as set forth in
this First Amendment, or which are different from, or not included in,
Landlord's standard improvement package items for the Building;

          5.2.6  Changes to the base, shell and core work of the Building
required by the Approved Working Drawings; or

          5.2.7  Any other acts or omissions of Tenant, or its agents, or
employees;

then, notwithstanding anything to the contrary set forth in this First Amendment
or this Tenant Work Letter and regardless of the actual date of the Substantial
Completion of the New Premises, the date of the Substantial Completion of the
New Premises shall be deemed to be the date the Substantial Completion of the
New Premises would have occurred if no Tenant delay or delays, as set forth
above, had occurred.

                                   SECTION 6

the Building and the New Premises, Contractor shall allow Tenant access to the 
New Premises prior to the Substantial Completion of the New Premises for the 
purpose of Tenant installing overstandard equipment or fixtures (including 
Tenant's data and telephone equipment) in the New Premises. Prior to Tenant's 
entry into the New Premises as permitted by the terms of this Section 6.1, 
Tenant shall submit a schedule to Landlord and Contractor, for their approval,

          -----------------------
its sole representative with respect to the matters set forth in this Tenant 
Work Letter, who, until further

                             EXHIBIT B-1 - Page 2

an item, if no written notice of approval is given or the item is not delivered 
within the stated time period, at Landlord's sole option, at the end of such 
period the item shall automatically be deemed approved or delivered by Tenant 
and the next succeeding time period shall commence. 

     6.6  Tenant's Lease Default.  Notwithstanding any provision to the contrary
          ----------------------
contained in the Lease, as amended, if an event of default as described in 
Section 19.1 of the Lease, as amended, or a default by Tenant under this Tenant 
Work Letter, has occurred at any time on or before the Substantial Completion of
the New Premises, then (i) in addition to all other rights and remedies granted 
to Landlord pursuant to the Lease, as amended, Landlord shall have the right to 
cause Contractor to cease the construction of the New Premises (in which case, 
Tenant shall be responsible for any delay in the Substantial Completion of the 
New Premises caused by such work stoppage as set forth in Section 5 of this 
Tenant Work Letter), and (ii) all other obligations of Landlord under the terms 
of this Tenant Work Letter shall be forgiven until such time as such default is
