                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                         September 30, 1995 AND 1994
                                 (Unaudited)

NOTE 1.  ORGANIZATION
   TENERA, Inc. (the "Company"), a Delaware corporation, was formed in 
connection with the conversion of TENERA, L.P. (the predecessor of the 
Company; the "Predecessor Partnership") into corporate form.
   On June 30, 1995, the Company completed its conversion to corporate form by 
means of a merger (the "Merger") of the Predecessor Partnership, its General 
Partner (Teknekron Technology MLP I Corporation) and its Operating Partnership 
(TENERA Operating Company, L.P.) with, and into, TENERA, Inc.  Pursuant to the 
Merger:  i) the Company succeeded to the business, assets, and liabilities of 
the Predecessor Partnership; ii) each limited partner Unit previously held by 
Unitholders in the Predecessor Partnership, (including 184,946 equivalent 
Units representing the interest in the Partnership of the General Partner), 
automatically converted to one share of Common Stock of TENERA, Inc.; and iii) 
an additional 1,123,596 shares of Common Stock were issued to the sole 
shareholder of the General Partner in consideration of the contribution of 
$1,000,000 made to TENERA, Inc. by the General Partner in connection with the 
Merger.  The Merger was approved by the Unitholders of the Predecessor 
Partnership pursuant to the Consent Solicitation Statement/Prospectus dated 
June 6, 1995, included in the Company's Registration Statement on Form S-4 
(Registration Number 33-58393; the "Form S-4").
   TENERA Rocky Flats, LLC ("LLC"), a Colorado limited liability company, was 
formed by the Company to provide the consulting services in connection with 
participation in the Performance Based Integrating Management Contract ("Rocky 
Flats Contract") at the Department of Energy's Rocky Flats Environmental 
Technology Site ("Site").

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
   Basis of Presentation.  The accompanying consolidated financial statements 
include the accounts of TENERA, Inc. consolidated with the LLC, and have been 
prepared by the Company without audit.  In the opinion of management, all 
adjustments (which include normal recurring adjustments) necessary to present 
fairly the financial position at September 30, 1995, and the results of 
operations and cash flows at September 30, 1995 and 1994, have been made.  For 
further information refer to the financial statements and notes thereto 
contained in the Form S-4. 
   Income Taxes.  As a result of the Company's conversion from partnership to 
corporate form on June 30, 1995, the Company is no longer subject to 
partnership tax treatment where the Company pays no tax itself on Company 
income.  Accordingly, the Company became a C Corporation subject to federal 
and state statutory income tax rates for income earned after the close of 
business on June 30, 1995.  A provision for income taxes has been made for the 
three months ended September 30, 1994, and no provision for income taxes has 
been made by the Company for the six months ended June 30, 1995.
   Per Share Information  In accordance with financial reporting guidelines, 
historical earnings per share information is deleted from the face of the 
historical income statements because this data is not indicative of the 
ongoing Company's change in tax treatment.  Pro forma per share data for the 
most recent year and interim period is shown.  Pro forma per share data 
assumes the Company is taxed for federal and state income tax purposes as a C 
Corporation at a 40% effective tax rate, and is computed on the basis of:  
weighted average of shares of Common Stock and Common Stock Equivalents 
outstanding during each period, and is adjusted for the assumed conversion of 
shares issuable upon exercise of options, after the assumed repurchase of 
Common Stock with the related proceeds.

</TABLE>
RESULTS OF OPERATIONS
   Higher revenue in the third quarter and lower general and administrative 
expenses resulted in an increase in pre-tax earnings of $207,000 in the third 
quarter of 1995.  During the first nine-month period of 1995, lower general 
and administrative expenses offset lower revenue.  These factors resulted in 
the Company reporting a nine-month pre-tax earnings of $789,000 in 1995, 
compared to a pre-tax loss of $139,000 in 1994 before the special item.
   The revenue increase in the third quarter reflects primarily the impact of 
beginning the Rocky Flats Contract at the Site on July 1, 1995.  Under terms 
of the cost-plus incentive fee Rocky Flats Contract, the Company will provide 
a minimum of 130 technical staff (with an estimated revenue for direct and 
overhead cost recovery exceeding $16 million and an, as yet, undetermined 
incentive fee percentage which is subject to final negotiation) in various 
positions at the Site during the first year of a two-year base period.  The 
total period of performance for the Rocky Flats Contract includes options to 
extend the contract, upon the request of Kaiser-Hill Company, LLC (the 
Integrating Contractor), through June 30, 2000.  Staffing for the Rocky Flats 
Contract was derived from two sources; i) recruitment of former Site 
employees; and ii) transfer of certain Company employees from the Government 
Services and Power Generation and Electric Utilities ("Power") Services 
groups.  The Rocky Flats Contract's impact on revenue was partially offset by 
impact of reduced technical services sales and staffing in the Power Services 
group when compared to the same period in 1994.  Although TENERA increased 
staffing for the Rocky Flats Contract in the third quarter, overall revenue 
for the first nine months of 1995 was down slightly from the comparable period 
in 1994.  This was primarily a result of lower overall technical services 
sales and staffing throughout the first six months of 1995 compared to 1994.

Concentration of revenue from the government sector increased to 60% and 44% 
of total revenue in the third quarter and first nine months of 1995, 
respectively, from 40% and 36% in the comparable periods of 1994.  This is 
primarily due to the Rocky Flats Contract activity which represented 42% and 
17% of total revenue in the third quarter and first nine months of 1995, 
respectively.  The number of clients served during the respective quarters, 
however, remained relatively constant at 61 in 1995 compared to 65 in 1994.  
Revenue from Software license and maintenance fees during the first nine 
months of 1995 rose to $593,000 from $291,000 in the comparable period of 
1994, primarily due to the recognition of license fees associated with 
achieving certain milestones in the ongoing New York Metropolitan Transit 
Authority installation.
   Direct costs were higher in the third quarter, reflecting the increased 
staffing for the Rocky Flats Contract.  Gross margin contribution from overall 
project activity during the third quarter, before considering the impact of 
Rocky Flats Contract, was up from 38% in 1994 to 41% in 1995.  These 1995 
margins reflect improved pricing in Power Services and achievement of 
milestones under software contracts.  The gross margin contribution in the 
quarter for the Rocky Flats Contract was only 17%.  This lower gross margin 
contribution is primarily due to the pricing characteristics of the contract, 
coupled with a low overhead cost structure for the LLC, and the lack of a fee 
recognition pending final negotiation of the amount.  Although staffing of the 
Rocky Flats Contract increased direct costs in the third quarter, overall 
direct costs for the first nine months of 1995 remained relatively constant 
with 1994.  Gross margin contribution from overall project activity during the 
nine-month period, before considering Rocky Flats, increased slightly to 41% 
in 1995 from 40% in 1994.
   General and administrative expenses decreased by $365,000 in the third 
quarter versus 1994, and by $1,912,000 in the first nine months of 1995 as 
compared to 1994, primarily due to overall reduced staff size during the first 
half of the year, improved technical staff productivity on direct projects, 
and lower professional services, facilities, travel and office equipment costs 
in 1995, partially offset by an incentive compensation award and costs 
associated with converting the Company structure to corporate form in 1995.  
These net cost reductions resulted in a drop in general and administrative 
expenses as a percentage of revenue in the third quarter and first nine months 
to 26% and 33%, respectively, from 38% and 41% in comparable periods in 1994.
   Other income for the first nine months of 1995 includes a gain on the sale 
of assets related to facility downsizing ($10,000).
   Net interest expense represents interest charges on borrowing under the 
Company's line of credit offset by earnings from the investment of cash 
balances in short-term, high-quality, corporate debt instruments.

LIQUIDITY AND CAPITAL RESOURCES
   Cash and cash equivalents decreased by $1,198,000 during the first nine 
months of 1995.  The decrease was due to cash used by operations ($1,167,000), 
and net acquisition of equipment ($99,000), offset by cash provided by 
financing activities ($68,000).
   Receivables increased by $1,896,000 from December 31, 1994, primarily due 
to an increase in quarterly revenue during the three months ended September 
30, 1995 compared to the fourth quarter of 1994.
   Accounts payable decreased by $752,000 during the period, primarily due to 
a decrease in overall general and administrative expenses.  Accrued 
compensation and related expenses increased by $532,000 during the period 
reflecting the increased staffing at September 30, 1995.
   Income taxes payable increased by $141,000 during the period representing 
the initial income tax provision for operation of the Company in a corporate 
form.
   Equity increased by $1,466,000 in the nine-month period ended September 30, 
1995, due to the receipt of additional capital ($1,000,000) in connection with 
the Merger, and net earnings ($648,000), partially offset by the repurchase of 
Units prior to the Merger ($182,000).
   No cash distribution was declared in 1995.
   The impact of inflation on revenue and projects of the Company was minimal.

   At September 30, 1995, the Company had available $4,500,000 of a $5,000,000 
revolving loan facility with its lender which expires in May 1996.  The 
Company has no outstanding borrowing against the line, however, $500,000 was 
assigned to support standby letters of credit.
   Management believes that cash expected to generated by operations, and the 
Company's working capital, and its loan facility are adequate to meet its 
anticipated liquidity needs through December 31, 1995.

                        PART II -- OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

   On October 13, 1995, the League for Coastal Protection ("League") filed an 
action against Pacific Gas & Electric Company ("PG&E"), a California 
corporation and TENERA, Inc., in the Superior Court of California for the 
County of San Francisco.  The action entitled League for Coastal Protection v. 
Pacific Gas & Electric Company, TENERA, Inc., et. al., Case No. 973182, 
alleges that PG&E and TENERA engaged in unfair business practices, violation 
of California and Federal environmental laws arising out of environmental 
studies performed in connection with the issuance of regulatory permits at 
PG&E's Diablo Canyon Power Plant, and seeks on behalf of the League and the 
general public, injunctive relief and unspecified damages.  The League has 
named TENERA in the action pursuant to a belief that it was an agent of PG&E 
and conspired with PG&E in the alleged violations.  TENERA's management 
anticipates that a claim based upon the same events may be filed in Federal 
Court under the Clean Water Act against the Company in the near future.  
Management believes that the Company will be able to defend this action 
successfully and does not believe that the eventual resolution of this matter 
will have a material effect on the Company's results of operations or 
financial position.  However, an adverse outcome could have a material adverse 
impact on the condition of the Company.  Moreover, unless indemnification or 
insurance coverage is obtained, of which there can be no assurances, the legal 
fees incurred by the Company in defending this action could have a material 
adverse effect on the Company's results of operations.

IV.  USE.  The Premises shall be used for the Permitted Use and for no other 
purpose.  Tenant agrees not to use or permit the use of the Premises for any 
purpose which is illegal, dangerous to life, limb or property or which, in 
Landlord's opinion, creates a nuisance or which would increase the cost of 
insurance coverage with respect to the Building.  Tenant shall conduct its 
business and control its agents, servants, contractors, employees, customers, 
licensees, and invitees in such a manner as not to interfere with, annoy or 
disturb other tenants, or in any way interfere with Landlord in the management 
and operation of the Building.  Tenant 

                                      3


<PAGE>
will maintain the Premises in a clean and healthful condition, and comply with 
all laws, ordinances, orders, rules and regulations of any governmental entity 
with reference to the operation of Tenant's business and to the use, 
condition, configuration or occupancy of the Premises, including without 
limitation, the Americans with Disabilities Act.  Tenant will comply with the 
rules and regulations of the Building adopted and altered by Landlord from 
time to time and will cause all of its agents, servants, contractors, 
employees, customers, licensees and invitees to do so.  All changes to such 
rules and regulations will be sent by Landlord to Tenant in writing.  A copy 
of the existing rules and regulations is attached hereto as Exhibit D and made 
a part hereof.  Tenant agrees not to commit or allow any waste to be committed 
on any portion of the Premises, and at the termination of this Lease to 
deliver up the Premises to Landlord in accordance with Article XXXV hereof.

V.  RENT.

    A.  Tenant covenants and agrees to pay to Landlord during the Lease Term, 
without any setoff or deduction whatsoever, the full amount of all Base Rental 
payments, and any adjustments thereof, due in accordance with the rental 
schedule set forth in Exhibit B-1 hereof (the "Base Rental"), the full amount 
of all payments of Additional Base Rental due in accordance with Exhibit B-2 
hereof (the "Additional Base Rental") and all such other sums of money as 
shall become due under this Lease (including, without limitation, any charges 
for replacement of electric lamps and ballasts and any other services, goods 
or materials furnished by Landlord at Tenant's request), all of which 
hereinafter may be collectively called "Rent."  Except as otherwise provided 
herein, the Base Rental  and Additional Base Rental for each calendar year or 
portion thereof during the Lease Term, shall be due and payable in advance in 
equal monthly installments on the first day of each calendar month during the 
Lease Term and any extensions or renewals hereof, and Tenant hereby agrees to 
pay such Base Rental and Additional Base Rental to Landlord without demand, 
provided that the installment of Base Rental for the first full calendar month 
of the Lease Term shall be payable upon the execution of this Lease by Tenant.  
If the Lease Term commences on a day other than the first day of a month or 
terminates on a day other than the last day of a month, then the installments 
of Base Rental and Additional Base Rental for such month or months shall be 
prorated, based on the number of days in such month.  All such payments shall 
be by a good and sufficient check.  No payment by Tenant or receipt or 
acceptance by Landlord of a lesser amount than the correct amount of Rent due 
under this Lease shall be deemed to be other than a payment on account of the 
earliest Rent due hereunder, nor shall any endorsement or statement on any 
check or any letter accompanying any check or payment be deemed an accord and 
satisfaction, and Landlord may accept such check or payment without prejudice 
to Landlord's right to recover the balance or pursue any other available 
remedy.  The acceptance by Landlord of any Rent on a date after the due date 
of such payment shall not be construed to be a waiver of Landlord's right to 
declare a default for any other late payment.  Tenant's covenant to pay Rent 
shall be independent of every other covenant set forth in this Lease.

    B.  All Rent not paid when due and payable shall bear interest from the 
date due until paid (provided Tenant shall be entitled to a grace period of 
five (5) days with respect to the first (1st) late payment in any calendar 
year) at the lesser of:  1. eighteen percent (18%) per annum; or 2. the 
Maximum Rate.  In addition, if Tenant fails to pay any installment of Base 
Rental, Additional Base Rental or any other item of Rent when due and payable 
hereunder (provided Tenant shall be entitled to a grace period of five (5) 
days with respect to the first (1st) late payment in any calendar year), a 
service fee equal to five percent (5%) of such unpaid amount will be due and 
payable immediately by Tenant to Landlord.

VI.  SECURITY DEPOSIT.  The Security Deposit shall be delivered to Landlord 
upon the execution of this Lease and shall be held by Landlord without 
liability for interest (except as required by law) and as security for the 
performance of Tenant's obligations under this Lease.  The Security Deposit 
shall not be considered an advance payment of Rent or a measure of Tenant's 
liability for damages.  Landlord may, from time to time, without prejudice to 
any other remedy, use all or a portion of the Security Deposit to make good 
any arrearages of Rent, to repair damages to the Premises caused by Tenant, to 
clean the Premises upon 

                                      4


<PAGE>
termination of this Lease or otherwise to satisfy any other covenant or 
obligation of Tenant hereunder.  Following any such application of the 
Security Deposit, Tenant shall pay to Landlord on demand the amount so applied 
in order to restore the Security Deposit to its original amount.  If Tenant is 
not in default at the termination of this Lease, after Tenant surrenders the 
Premises to Landlord in accordance with this Lease and all amounts due 
Landlord from Tenant are finally determined and paid, the balance of the 
Security Deposit remaining after any such application shall be returned to 
Tenant.  If Landlord transfers its interest in the Premises during the Lease 
Term, Landlord may assign the Security Deposit to the transferee and 
thereafter shall have no further liability for the return of such Security 
Deposit.  Tenant agrees to look solely to such transferee or assignee for the 
return of the Security Deposit.  Landlord and its successors and assigns shall 
not be bound by any actual or attempted assignment or encumbrance of the 
Security Deposit by Tenant, provided, however, if Tenant's interest in this 
Lease has been assigned, Landlord may, at its option, and provided the 
assignee provides Landlord with written evidence of such assignment, return 
the Security Deposit to such assignee, provided further that the assignee has 
complied with the other terms of this paragraph.  If Landlord elects to return 
the Security Deposit to Tenant's assignee as aforesaid, Landlord will have no 
further obligation to the original tenant with respect thereto.  Landlord 
shall not be required to keep the Security Deposit separate from its other 
accounts.

VII.  SERVICES TO BE FURNISHED BY LANDLORD.

    A.  Subject to the provisions of Article XI below, Landlord, as part of 
Basic Costs, agrees to furnish Tenant the following services:

        1.  Cold water at those points of supply provided for general use of 
tenants in the Building, central heat and air conditioning in season, at such 
temperatures and in such amounts as are considered by Landlord to be standard 
for buildings of similar class, size, age and location, or as required by 
governmental authority; provided, however, heating and air conditioning 
service at times other than for Normal Business Hours for the Building shall 
be furnished only upon the written request of Tenant delivered to Landlord at 
the office of the Building prior to 3:00 p.m. at least one Business Day in 
advance of the date for which such usage is requested.  Tenant shall pay 
Landlord, upon demand as additional rent, the entire cost of additional 
service as such costs are determined by Landlord from time to time.

        2.  Routine maintenance and electric lighting service for all Common 
Areas of the Building in the manner and to the extent deemed by Landlord to be 
standard for buildings of similar class, size, age and location.

        3.  Janitor service on Business Days; provided, however, if Tenant's 
use, floor covering or other improvements require special services, Tenant 
shall, at Landlord's option, either (i) retain its own contractors (which 
contractor shall be subject to Landlord's reasonable approval) to do such work 
or, (ii) pay the additional cost reasonably attributable thereto as additional 
Rent upon presentation of statements therefor by Landlord.

        4.  Elevator service in common with other tenants of the Building for 
ingress and egress to and from the floor of the Premises during Normal 
Business Hours.

    B.  Except as otherwise expressly provided herein, the failure by Landlord 
to any extent to furnish, or the interruption or termination of these services 
in whole or in part, resulting from adherence to laws, regulations and 
administrative orders, wear, use, repairs, improvements, alterations, Force 
Majeure (as hereinafter defined) or any causes beyond the reasonable control 
of Landlord shall not render Landlord liable in any respect nor be construed 
as an eviction of Tenant, nor give rise to an abatement of Rent, nor relieve 
Tenant from the obligation to fulfill any covenant or agreement hereof.  
Notwithstanding anything to the contrary contained in this Section VII.B. if 
(i) Landlord ceases to furnish any service in the Building, and Tenant 
notifies Landlord of such cessation in writing (the "Interruption Notice"), 
(ii) such cessation does not arise as a result of an act or omission of 
Tenant, (iii) such cessation is not caused by a fire or other casualty (in 

                                      5


<PAGE>
which case Article XIX shall control), (iv) the repair or restoration of such 
service is reasonably within the control of Landlord, and (v) as a result of 
such cessation, the Premises or a material portion thereof, is rendered 
untenantable (meaning that Tenant is unable to use the Premises in the normal 
course of its business) and Tenant in fact ceases to use the Premises, or 
material portion thereof, then, Tenant's sole remedy for such cessation shall 
be as follows:  on the fifth (5th) consecutive business day following the 
later to occur of the date the Premises (or material portion thereof) becomes 
untenantable, the date Tenant ceases to use such space and the date Tenant 
provides Landlord with an Interruption Notice, the Base Rental and Additional 
Base Rental payable hereunder shall be abated on a per diem basis for each day 
after such five (5) business day period based upon the percentage of the 
Premises so rendered untenantable and not used by Tenant, and such abatement 
shall continue until the date the Premises become tenantable again.  Should 
any of the equipment or machinery used in the provision of such services for 
any cause cease to function properly, Landlord shall use reasonable diligence 
to repair such equipment or machinery, but except as otherwise expressly 
provided herein, Tenant shall have no claim for offset or abatement of Rent or 
damages on account of an interruption in service or resulting therefrom.  
Landlord's entire obligation with respect to the repair and maintenance of the 
Premises are set forth above.

    C.  Tenant expressly acknowledges that if Landlord, from time to time, 
elects to provide security services, Landlord shall not be deemed to have 
warranted the efficiency of such security personnel, service, procedures or 
equipment and Landlord shall not be liable in any manner for the failure of 
any such security personnel, services, procedures or equipment to prevent or 
control, or apprehend any one suspected of personal injury or property damage 
in, on or around the Property.

VIII.  LEASEHOLD IMPROVEMENTS.

    A.  Except as otherwise specifically provided elsewhere in this Lease or 
in the Work Letter Agreement, if any, attached hereto as Exhibit C and 
incorporated herein, all installations and improvements now or hereafter 
placed on or in the Premises by Landlord shall be for Tenant's account and at 
Tenant's cost, which cost shall be payable by Tenant to Landlord upon demand 
as additional Rent.

    B.  Any and all alterations, additions and improvements to the Premises, 
all attached furniture, equipment and non-trade fixtures (collectively, 
"Leasehold Improvements") shall be owned and insured by Landlord and shall 
remain upon the Premises, all without compensation, allowance or credit to 
Tenant.  Any unattached and movable equipment or furniture, trade fixtures or 
other personalty of Tenant ("Tenant's Property") shall be owned and insured by 
Tenant.  Landlord may, nonetheless, require Tenant to remove any Leasehold 
Improvements performed by or for the benefit of Tenant and all electronic, 
phone and data cabling as are designated by Landlord (the "Required 
Removables") at Tenant's sole cost.  In the event that Landlord so elects, 
Tenant shall remove such Required Removables on or before the expiration or 
earlier termination of this Lease and repair any damage caused by such 
removal.  If Tenant fails to remove the Required Removables after Landlord's 
request therefor, Landlord may remove, store or dispose of the Required 
Removables at Tenant's cost, and repair any damage caused by such removal and 
Tenant shall pay Landlord as additional Rent hereunder, on demand, all such 
costs.  Landlord shall not require Tenant to remove any usual office 
improvements such as gypsum board, partitions, ceiling grids and tiles, 
fluorescent lighting panels, building standard doors and carpeting.

IX.  GRAPHICS.  Landlord shall provide and install, at Tenant's cost which may 
be paid out of the Work Allowance (defined in Exhibit C), all letters or 
numerals on the exterior of the Premises; all such letters and numerals shall 
be in the standard graphics for the Building and no others shall be used or 
permitted on the Premises without Landlord's prior written consent.  

                                      6


<PAGE>
X.  REPAIRS AND ALTERATIONS BY TENANT. 

    A.  Tenant shall, at Tenant's own cost and expense, keep the Premises in 
good condition and repair.  Such repairs shall restore the Premises to as good 
a condition as it was in prior to such damage and shall be effected in 
compliance with the reasonable directions of Landlord.  If Tenant fails to 
make such repairs to the Premises promptly, Landlord may, at its option, make 
such repairs, and Tenant shall pay the cost thereof to the Landlord on demand 
as additional Rent.

    B.  Tenant shall not make or allow to be made any alterations, additions 
or improvements to the Premises, nor install any vending machines, safes or 
other heavy property or equipment within the Premises, nor place signs or 
window coverings on the Premises which are visible from outside the Premises, 
without first obtaining the written consent of Landlord in each such instance.  
Except with regard to requests for consent or approval that require Landlord 
to make a determination of the aesthetics of certain signage, alterations or 
other things that would be visible form outside the Premises or Building or to 
assume certain risks, including, without limitation, the risk that a certain 
alteration, addition and/or improvement could adversely affect the mechanical 
systems or structure of the Building or require excess removal costs, Landlord 
agrees to act reasonably in granting its approval or disapproval of any 
requests by Tenant for the consent or approval of Landlord.  Prior to 
commencing any such work, Tenant must furnish Landlord with plans and 
specifications; names and addresses of contractors; copies of contracts; 
necessary permits; evidence of contractor's and subcontractor's insurance in 
accordance with section XVI.B. hereof; and indemnification in form and amount 
satisfactory to Landlord.  All such improvements, alterations or additions 
shall be installed in a good workmanlike manner using new materials.  Upon 
completion, Tenant shall furnish "as-built" plans, contractor's affidavits and 
full and final waivers of lien and receipted bills covering all labor and 
materials.  All improvements, alterations and additions shall comply with all 
insurance requirements, codes, ordinances, laws and regulations, including 
without limitation, the Americans with Disabilities Act.  Tenant shall 
reimburse Landlord upon demand as additional Rent for all sums expended by 
Landlord for examination of the architectural, mechanical, electric and 
plumbing plans for any alterations, additions or improvements and for the 
costs of repairing any damage done to the Building caused by Tenant or 
Tenant's agents, servants, employees, customers, licensees, or invitees.  If 
Landlord so requests, Tenant shall permit Landlord to supervise construction 
operations, but no such supervision shall impose any liability upon Landlord.  
In the event Landlord supervises such construction, Landlord shall be entitled 
to a supervisory fee in the amount of fifteen percent (15%) of the cost of 
such construction.  Landlord's approval of Tenant's plans and specifications 
or supervision of any work performed for or on behalf of Tenant shall not be 
deemed to be a representation by Landlord that such plans and specifications 
comply with applicable insurance requirements, building codes, ordinances, 
laws or regulations.

XI.  USE OF ELECTRICAL AND HVAC SERVICES BY TENANT.

    A.  All electricity used by Tenant in the Premises shall, at Landlord's 
option, be paid for by Tenant through inclusion in Base Rental or Basic Costs.  
Tenant's use of electrical and heating, ventilating and air conditioning 
("HVAC") services furnished by Landlord shall not exceed, either in voltage, 
rated capacity, use or overall load, that which Landlord deems to be standard 
for the Building.  In the event Tenant shall request that it be allowed to 
consume electrical or HVAC services in excess of that deemed by Landlord to be 
standard for the Building, Landlord may refuse to consent to such usage or may 
consent upon such conditions as Landlord elects (including the installation of 
utility service upgrades, submeters, air handlers or cooling units), and all 
such additional usage (to the extent permitted by law), installation and 
maintenance thereof shall be paid for by Tenant as additional Rent.  Landlord 
shall have the right to separately meter electrical usage for the Premises at 
any time during the Lease Term or to use any other method of measuring 
electrical usage that Landlord, in its reasonable judgment, deems to be 
appropriate.

    B.  If Landlord generates or distributes electric current for the 
Building, Tenant shall obtain all current from Landlord and pay as additional 
Rent Landlord's charges therefor, provided, however, that if the cost of 
providing electricity is not 

                                      7


<PAGE>
included in Base Rental or Basic Costs, the charges to Tenant shall not exceed 
the rate that would be charged Tenant if billed directly by the local utility 
for the same services.  Landlord may cease to furnish electricity upon 30 days 
prior written notice, provided within the 30 days Landlord connects with 
another source of electric supply.

XII.  ENTRY BY LANDLORD.  Landlord and its agents or representatives shall 
have the right to enter the Premises with reasonable prior notice (and in 
emergencies at all times, without prior notice, by any means Landlord may deem 
appropriate, and without liability therefor) to inspect the same, or to show 
the Premises to prospective purchasers, mortgagees, tenants or insurers, or to 
clean or make repairs, alterations or additions thereto, including any work 
that Landlord deems necessary for the safety, protection or preservation of 
the Building or any occupants thereof, or to facilitate repairs, alterations 
or additions to the Building or any other tenants premises.  If reasonably 
necessary for the protection and safety of Tenant and its employees, Landlord 
shall have the right to temporarily close the Premises to perform repairs, 
alterations or additions in the Premises, provided that Landlord shall use 
reasonable efforts to perform all such work on weekends and after Normal 
Business Hours.  Entry by Landlord hereunder shall not constitute a 
constructive eviction or entitle Tenant to any abatement or reduction of Rent 
by reason thereof.  Notwithstanding the foregoing, Landlord and its agents and 
representatives shall not have to provide Tenant with prior notice to perform 
janitor and cleaning service in the Premises before or after Normal Business 
Hours.

XIII.  ASSIGNMENT AND SUBLETTING.

    A.  Tenant shall not assign, sublease, transfer or encumber this Lease or 
any interest therein or grant any license, concession or other right of 
occupancy of the Premises or any portion thereof or otherwise permit the use 
of the Premises or any portion thereof by any party other than Tenant (any of 
which events is hereinafter called a "Transfer") without the prior written 
consent of Landlord, which consent shall not be unreasonably withheld with 
respect to any proposed assignment or subletting.  Landlord's consent shall 
not be considered unreasonably withheld if:  1. the proposed transferee's 
financial responsibility does not meet the same criteria Landlord uses to 
select Building tenants, provided with respect to a subtenant, Landlord shall 
apply a standard of whether the proposed subtenant is financially able to meet 
its obligations, including its obligation to pay rent under the sublease, as 
they become due; 2. the proposed transferee's business is not suitable for the 
Building considering the business of the other tenants and the Building's 
prestige or would result in a violation of an exclusive right granted to 
another tenant in the Building; 3. the proposed use is different than the 
Permitted Use; 4. the proposed transferee is a government agency or occupant 
of the Project; or 5. Tenant is in default.  Tenant acknowledges that the 
foregoing is not intended to be an exclusive list of the reasons for which 
Landlord may reasonably withhold its consent to a proposed Transfer.  Any 
attempted Transfer in violation of the terms of this Article shall, at 
Landlord's option, be void.  Consent by Landlord to one or more Transfers 
shall not operate as a waiver of Landlord's rights as to any subsequent 
Transfers.  In addition, Tenant shall not, without Landlord's consent, 
publicly offer or advertise the Lease for Transfer in any media.  In the event 
Tenant or anyone acting on behalf of Tenant or with Tenant's knowledge 
violates the provisions of the foregoing sentence, Landlord, in addition to 
its other remedies, shall be entitled to seek injunctive relief preventing 
such action, and Tenant shall be responsible for all costs incurred by 
Landlord in connection therewith.

    B.  If Tenant requests Landlord's consent to a Transfer, Tenant shall 
notify Landlord in writing at least 45 days prior to the effective date of the 
proposed Transfer of the name of the proposed transferee and the nature of the 
business of the proposed transferee, the term, use, rental rate and all other 
material terms and conditions of the proposed Transfer, including, without 
limitation, evidence satisfactory to Landlord that the proposed transferee is 
financially responsible.  Notwithstanding the provisions of Section XIII.A. 
above, Landlord may, during said 45-day period, 1. consent to or refuse to 
consent to such Transfer in writing; or 2. negotiate directly with the 
proposed transferee and (in the event Landlord is able to reach agreement with 
such proposed transferee) upon execution of a lease with such transferee, 
terminate this Lease (in part or in whole, as appropriate) upon thirty (30) 
days' notice; or 3. cancel and terminate this Lease, in whole or in part as 

                                      8


<PAGE>
appropriate, upon 30 days notice.  In the event Landlord consents to any such 
Transfer, the Transfer shall be in a form approved by Landlord, and Tenant 
shall bear all costs and expenses incurred by Landlord in connection with the 
review and approval of such documentation, which costs and expenses shall not 
exceed Seven Hundred Fifty Dollars ($750.00).

    C.  Fifty percent (50%) of all cash or other proceeds (the "Transfer 
Consideration") of any Transfer of Tenant's interest in this Lease and/or the 
Premises, whether consented to by Landlord or not, shall be paid to Landlord 
and Tenant hereby assigns all rights it might have or ever acquire in any such 
proceeds to Landlord.  In addition to the Rent hereunder, Tenant hereby 
covenants and agrees to pay to Landlord fifty percent (50%) of all rent and 
other consideration which it receives which is in excess of the Rent payable 
hereunder within ten (10) days following receipt thereof by Tenant.  In 
addition to any other rights Landlord may have, Landlord shall have the right 
to contact any transferee and require that all payments made pursuant to the 
Transfer shall be made directly to Landlord.  

    D.  If Tenant is a corporation and if at any time during the Lease Term 
the person or persons who own the voting shares at the time of the execution 
of this Lease cease for any reason, including but not limited to merger, 
consolidation or other reorganization involving another corporation, to own a 
majority of such shares, or if Tenant is a partnership and if at any time 
during the Lease Term the general partner or partners who own the general 
partnership interests in the partnership at the time of the execution of this 
Lease, cease for any reason to own a majority of such interests (except as the 
result of transfers by gift, bequest or inheritance to or for the benefit of 
members of the immediate family of such original shareholder(s) or 
partner(s)), such an event shall be deemed to be a Transfer.  The preceding 
sentence shall not apply whenever Tenant is a corporation the outstanding 
stock of which is listed on a recognized security exchange, or if at least 
eighty per cent (80%) of its voting stock is owned by another corporation, the 
voting stock of which is so listed.

    E.  Any Transfer consented to by Landlord in accordance with this Article 
XIII shall be only for the Permitted Use and for no other purpose, and in no 
event shall any Transfer release or relieve Tenant or any Guarantors from any 
obligations under this Lease.

XIV.  LIENS.  Tenant will not permit any mechanic's liens or other liens to be 
placed upon the Premises or Tenant's leasehold interest therein, the Building, 
or the real estate associated therewith.  Landlord's title to the Building and 
Project is and always shall be paramount to the interest of Tenant, and 
nothing herein contained shall empower Tenant to do any act that can, shall or 
may encumber Landlord's title.  In the event any such lien does attach, Tenant 
shall, within 5 days of notice of the filing of said lien, either discharge or 
bond over such lien to the satisfaction of Landlord and Landlord's Mortgagee 
(as hereinafter defined), and in such a manner as to stay the enforcement or 
foreclosure of such lien.  If Tenant shall fail to so discharge or bond over 
such lien, then, in addition to any other right or remedy of Landlord, 
Landlord may, but shall not be obligated to, discharge the same.  Any amount 
paid by Landlord for any of the aforesaid purposes, including reasonable 
attorneys fees (if and to the extent permitted by law) shall be paid by Tenant 
to Landlord on demand as additional Rent.

XV.  INDEMNITY AND WAIVER OF CLAIMS.

    A.  Except for losses, liabilities, obligations, damages, penalties, 
claims, costs, charges, and expenses resulting from the negligence of Landlord 
and/or its agents, employees or contractors, and subject to the provisions of 
Article XVII hereof, Tenant shall indemnify, defend and hold Landlord, its 
principals, beneficiaries, partners, officers, directors, agents, employees 
and any Mortgagee(s) (collectively the  "Landlord Related Parties") harmless 
against and from all liabilities, obligations, damages, penalties, claims, 
costs, charges and expenses, including, without limitation, reasonable 
architects' and attorneys' fees (if and to the extent permitted by law), which 
may be imposed upon, incurred by, or asserted against Landlord or any of the 
Landlord Related Parties and arising, directly or indirectly, out of or in 
connection with the use, occupancy or maintenance of the Premises by, through 
or under Tenant, and (without limiting the generality of the foregoing) 

                                      9


<PAGE>
any of the following:  1. any work or thing done in, on or about the Premises 
or any part thereof by Tenant or any of its transferees, agents, servants, 
contractors, employees, customers, licensees or invitees; 2. any use, non-use, 
possession, occupation, condition, operation or maintenance of the Premises or 
any part thereof; 3. any act or omission of Tenant or any of its transferees, 
agents, servants, contractors, employees, customers, licensees or invitees, 
regardless of whether such act or omission occurred within the Premises; 4. 
any injury or damage to any person or property occurring in, on or about the 
Premises or any part thereof; or 5. any failure on the part of Tenant to 
perform or comply with any of the covenants, agreements, terms or conditions 
contained in this Lease with which Tenant must comply or perform.  In case any 
action or proceeding is brought against Landlord or any of the Landlord 
Related Parties by reason of any of the foregoing, Tenant shall, at Tenant's 
sole cost and expense, resist and defend such action or proceeding with 
counsel approved by Landlord or, at Landlord's option, reimburse Landlord for 
the cost of any counsel retained directly by Landlord to defend and resist 
such action or proceeding.

    B.  Landlord and the Landlord Related Parties shall not be liable for, and 
Tenant waives, all claims for loss or damage to Tenant's business or damage to 
person or property sustained by Tenant or any person claiming by, through or 
under Tenant (including Tenant's employees) resulting from any accident or 
occurrence in, on or about the Premises, the Building or the Project, 
including, without limitation, claims for loss, theft or damage resulting 
from:  1. the Premises, Building, or Project, or any equipment or 
appurtenances becoming out of repair; 2. wind or weather; 3. any defect in or 
failure to operate, for whatever reason, any sprinkler, heating or air-
conditioning equipment, electric wiring, gas, water or steam pipes; 4. broken 
glass; 5. the backing up of any sewer pipe or downspout; 6. the bursting, 
leaking or running of any tank, water closet, drain or other pipe; 7. the 
escape of steam or water; 8. water, snow or ice being upon or coming through 
the roof, skylight, stairs, doorways, windows, walks or any other place upon 
or near the Building; 9. the falling of any fixture, plaster, tile or other 
material; 10. any act, omission or negligence of other tenants, licensees or 
any other persons or occupants of the Building or of adjoining or contiguous 
buildings, of owners of adjacent or contiguous property or the public, or by 
construction of any private, public or quasi-public work; or 11. any other 
cause of any nature except, as to items 1. - 9., where such loss or damage is 
due to Landlord's negligence or willful failure to make repairs required to be 
made pursuant to other provisions of this Lease, after the expiration of a 
reasonable time after written notice to Landlord of the need for such repairs.  
To the maximum extent permitted by law, Tenant agrees to use and occupy the 
Premises, and to use such other portions of the Project as Tenant is herein 
given the right to use, at Tenant's own risk.

    C.  Except for losses, liabilities, obligations, damages, penalties, 
claims, costs, charges and expenses resulting from the negligence of Tenant 
and/or its agents, employees or contractors, and subject to the provisions of 
Article XVII hereof, Landlord shall indemnify, defend and hold Tenant, its 
principals, agents and employees (collectively the "Tenant Related Parties") 
harmless from and against all liabilities, obligations, damages (other than 
consequential damages), penalties, claims, costs, charges and expenses, 
including, without limitation, reasonable attorneys' fees, which may be 
imposed upon, incurred by, or asserted against Tenant or any of the Tenant 
Related Parties and arising, directly or indirectly, out of or in connection 
with any of the following:(i) any work or thing done in, on or about the 
Common Areas or any part thereof by Landlord or any of its agents, contractors 
or employees; (ii) any use, non-use, possession, occupation, condition, 
operation, maintenance or management of the Common Areas or any part thereof 
by Landlord or any of its agents, contractors or employees (iii) any act or 
omission of Landlord or any of its agents, contractors or employees; and (iv) 
any injury or damage to any person or property occurring in, on or about the 
Common Areas or any part thereof; provided, however, that in each case such 
liability, obligation, damage, penalty, claim, cost, charge or expense results 
from the negligence of Landlord and/or its agents, employees or contractors.

    D.  Subject to the provisions of Articles X, XXII and XXIII hereof, Tenant 
and the Tenant Related Parties shall not be liable for, and Landlord waives, 
all claims for loss or damage to Landlord's business or damage to person or 
property sustained 

                                     10


<PAGE>
by Landlord or any person claiming by, through or under Landlord (including 
Landlord's employees) resulting from any accident or occurrence in, on or 
about the Premises, the Building or the Property, including, without 
limitation, claims for loss, theft or damage resulting from: (1) the Premises, 
Building, or Property, or any equipment or appurtenances becoming out of 
repair: (2) wind or weather; (3) any defect in or failure to operate, for 
whatever reason, any sprinkler, heating or air-conditioning equipment,

private, public or quasi-public work; or (11) any other cause of any nature 
except, as to items (1) - (9), where such loss or damage is due to Tenant's 
negligence or willful failure to make repairs required to be made pursuant to 
other provisions of this Lease.

XVI.  TENANT'S INSURANCE.

    A.  At all times commencing on and after the earlier of the Commencement 
Date and the date Tenant or its agents, employees or contractors enters the 
Premises for any purpose, Tenant shall carry and maintain, at its sole cost 
and expense:

        1.  Commercial General Liability Insurance with a Broad Form General 
Liability Endorsement applicable to the Premises and its appurtenances 
providing, on an occurrence basis, a minimum combined single limit of Two 
Million Dollars ($2,000,000).

        2.  All Risks of Physical Loss Insurance written at replacement cost 
value and with a replacement cost endorsement covering all of Tenant's 
Property in the Premises.

        3.  Workers Compensation Insurance as required by the state in which 
the Premises is located and in amounts as may be required by applicable 
statute, and Employers Liability Coverage of One Million Dollars ($1,000,000) 
per occurrence.

        4.  Whenever good business practice, in Landlord's reasonable 
judgment, indicates the need of additional insurance coverage or different 
types of insurance in connection with the Premises or Tenant's use and 
occupancy thereof, Tenant shall, upon request, obtain such insurance at 
Tenant's expense and provide Landlord with evidence thereof.

    B.  Except for items for which Landlord is responsible under the Work 
Letter Agreement, before any repairs, alterations, additions, improvements, or 
construction are undertaken by or on behalf of Tenant, Tenant shall carry and 
maintain, at its expense, or Tenant shall require any contractor performing 
work on the Premises to carry and maintain, at no expense to Landlord, in 
addition to worker's compensation insurance as required by the jurisdiction in 
which the Building is located, All Risk Builder's Risk Insurance in the amount 
of the replacement cost of any alterations, additions or improvements (or such 
other amount reasonably required by Landlord) and Commercial General Liability 
Insurance (including, without limitation, Contractor's Liability coverage, 
Contractual Liability coverage, Completed Operations coverage, a Broad Form 
Property Damage coverage and Contractor's Protective liability) written on an 
occurrence basis with a minimum combined single limit of Two Million Dollars 
($2,000,000); such limit may be accomplished by means of an umbrella policy.

    C.  Any company writing any insurance which Tenant is required to maintain 
or cause to be maintained pursuant to the terms of this Lease (all such 
insurance as well as any other insurance pertaining to the Premises or the 
operation of Tenant's business therein being referred to as "Tenant's 
Insurance"), as well as the form of such insurance, shall at all times be 
subject to Landlord's reasonable 

                                     11


<PAGE>
approval, and each such insurance company shall have an A.M. Best rating of 
"A7" or better and shall be licensed and qualified to do business in the state 
in which the Premises are located.  All policies evidencing Tenant's Insurance 
(except for Workers Compensation) shall specify Tenant and the "owner[s] of 
the Building and its (or their) respective principals, beneficiaries, 
partners, officers, directors, employees, agents and mortgagee[s]" (and any 
other designees of Landlord as the interest of such designees shall appear) as 
additional insureds.  Provided that the coverage afforded Landlord and any 
designees of Landlord shall not be reduced or otherwise adversely affected, 
all of Tenant's Insurance may be carried under a blanket policy covering the 
Premises and any other of Tenant's locations.  All liability policies of 
Tenant's Insurance shall contain endorsements that the insurer(s) will give to 
Landlord and its designees at least thirty (30) days' advance written notice 
of any change, cancellation, termination or lapse of said insurance.  Tenant 
shall be solely responsible for payment of premiums for all of Tenant's 
Insurance.  Tenant shall deliver to Landlord at least fifteen (15) days prior 
to the time Tenant's Insurance is first required to be carried by Tenant, and 
upon renewals at least fifteen (15) days prior to the expiration of any such 
insurance coverage, a certificate of insurance of all policies procured by 
Tenant in compliance with its obligations under this Lease.  The limits of 
Tenant's Insurance shall in no event limit Tenant's liability under this 
Lease.

    D.  Tenant shall not do or fail to do anything in, upon or about the 
Premises which will:  1. violate the terms of any of Landlord's insurance 
policies; 2. prevent Landlord from obtaining policies of insurance acceptable 
to Landlord or any Mortgagees; or 3. result in an increase in the rate of any 
insurance on the Premises, the Building, any other property of Landlord or of 
others within the Building.  In the event of the occurrence of any of the 
events set forth in this Section, Tenant shall pay Landlord upon demand, as 
additional Rent, the cost of the amount of any increase in any such insurance 
premium.  If Tenant fails to obtain the insurance coverage required by this 
Lease, Landlord may, at its option, obtain such insurance for Tenant, and 
Tenant shall pay, as additional Rent, the cost of all premiums thereon and all 
of Landlord's costs associated therewith.

XVII.  SUBROGATION.  Notwithstanding anything set forth in this Lease to the 
contrary, Landlord and Tenant do hereby waive any and all right of recovery, 
claim, action or cause of action against the other, their respective 
principals, beneficiaries, partners, officers, directors, agents, and 
employees, and, with respect to Landlord, its Mortgagee[s], for any loss or 
damage that may occur to Landlord or Tenant or any party claiming by, through 
or under Landlord or Tenant, as the case may be, with respect to their 
respective property, the Building, the Property or the Premises or any 
addition or improvements thereto, or any contents therein, by reason of fire, 
the elements or any other cause, regardless of cause or origin, including the 
negligence of Landlord or Tenant, or their respective principals, 
beneficiaries, partners, officers, directors, agents and employees and, with 
respect to Landlord, its Mortgagee[s], which loss or damage is (or would have 
been, had the insurance required by this Lease been carried) covered by 
insurance.  Since this mutual waiver will preclude the assignment of any such 
claim by subrogation (or otherwise) to an insurance company (or any other 
person), Landlord and Tenant each agree to give each insurance company which 
has issued, or in the future may issue, its policies of fire, extended 
coverage or material damage insurance, written notice of the terms of this 
mutual waiver, and to have such insurance policies properly endorsed, if 
necessary, to prevent the invalidation of any of the coverage provided by such 
insurance policies by reason of such mutual waiver.  For the purpose of the 
foregoing waiver, the amount of any deductible applicable to any loss or 
damage shall be deemed covered by, and recoverable by the insured under the 
insurance policy to which such deductible relates.  In the event that Tenant 
is permitted to and self-insures any risk which would have been covered by the 
insurance required to be carried by Tenant pursuant to Article XVI of the 
Lease, or if Tenant fails to carry any insurance required to be carried by 
Tenant pursuant to Article XVI of this Lease, then all loss or damage to 
Tenant, its leasehold interest, its business, its property, the Premises or 
any additions or improvements thereto or contents thereof shall be deemed 
covered by and recoverable by Tenant under valid and collectible policies of 
insurance.

                                     12


<PAGE>

XVIII.  LANDLORD'S INSURANCE.  Landlord shall maintain property insurance on 
the Building in such amounts as Landlord reasonably elects, provided that 
during the Lease Term Landlord shall maintain standard so-called "all risk" 
property insurance covering the Building in an amount equal to the replacement 
cost thereof (including Leasehold Improvements approved by Landlord) at the 
time in question.  The cost of such insurance shall be included as a part of 
the Basic Costs, and payments for losses thereunder shall be made solely to 
Landlord or the Mortgagees of Landlord as their interests shall appear.

XIX.  CASUALTY DAMAGE.  If the Premises or any part thereof shall be damaged 
by fire or other casualty, Tenant shall give prompt written notice thereof to 
Landlord.  In case the Building shall be so damaged that substantial 
alteration or reconstruction of the Building shall, in Landlord's sole 
opinion, be required (whether or not the Premises shall have been damaged by 
such casualty) or in the event the Premises have been damaged and there is 
less than two (2) years of the Lease Term remaining on the date of such 
casualty or in the event any Mortgagee should require that the insurance 
proceeds payable as a result of a casualty be applied to the payment of the 
mortgage debt or in the event of any material uninsured loss to the Building, 
Landlord may, at its option, terminate this Lease by notifying Tenant in 
writing of such termination within ninety (90) days after the date of such 
casualty.  Such termination shall be effective as of the date of fire or 
casualty, with respect to any portion of the Premises that was rendered 
untenantable, and the date specified in Landlord's notice, with respect to any 
portion of the Premises that remained tenantable.  If Landlord does not elect 
to terminate this Lease, Landlord shall commence and proceed with reasonable 
diligence to restore the Building (provided that Landlord shall not be 
required to restore any unleased premises in the Building) and the Leasehold 
Improvements (but excluding any improvements, alterations or additions made by 
Tenant in violation of this Lease) located within the Premises, if any, which 
Landlord has insured to substantially the same condition they were in 
immediately prior to the happening of the casualty.  Notwithstanding the 
foregoing, Landlord's obligation to restore the Building, and the Leasehold 
Improvements, if any, shall not require Landlord to expend for such repair and 
restoration work more than the insurance proceeds actually received by the 
Landlord as a result of the casualty.  When repairs to the Premises have been 
completed by Landlord, Tenant shall complete the restoration or replacement of 
all Tenant's Property necessary to permit Tenant's reoccupancy of the 
Premises, and Tenant shall present Landlord with evidence satisfactory to 
Landlord of Tenant's ability to pay such costs prior to Landlord's 
commencement of repair and restoration of the Premises.  Landlord shall not be 
liable for any inconvenience or annoyance to Tenant or injury to the business 
of Tenant resulting in any way from such damage or the repair thereof, except 
that, subject to the provisions of the next sentence, Landlord shall allow 
Tenant a fair diminution of Rent on a per diem basis during the time and to 
the extent the Premises are untenantable.  If the Premises or any other 
portion of the Building is damaged by fire or other casualty resulting from 
the fault or negligence of Tenant or any of Tenant's agents, employees, or 
contractors, the Rent hereunder shall not be diminished during any period 
during which the Premises, or any portion thereof, is untenantable, and Tenant 
shall be liable to Landlord for the cost of the repair and restoration of the 
Building caused thereby to the extent such cost and expense is not covered by 
insurance proceeds.  Landlord and Tenant hereby waive the provisions of any 
law from time to time in effect during the Lease Term relating to the effect 
upon leases of partial or total destruction of leased property.  Landlord and 
Tenant agree that their respective rights in the event of any damage to or 
destruction of the Premises shall be those specifically set forth herein.

XX.  DEMOLITION.  INTENTIONALLY OMITTED.

XXI.  CONDEMNATION.  If 1. the whole or any substantial part of the Premises 
or 2. any portion of the Building or Project which would leave the remainder 
of the Building unsuitable for use as an office building comparable to its use 
on the Commencement Date, shall be taken or condemned for any public or quasi-
public use under governmental law, ordinance or regulation, or by right of 
eminent domain, or by private purchase in lieu thereof, then Landlord may, at 
its option, terminate this Lease effective as of the date the physical taking 
of said Premises or said portion of the Building or Project shall occur.  
Notwithstanding the foregoing, if the whole or any substantial part of the 
Premises shall be taken or 

                                     13


<PAGE>
condemned for any public or quasi-public use under governmental law, ordinance 
or regulation, or by right of eminent domain, or by private purchase in lieu 
thereof, Tenant shall also have the right to terminate this Lease effective as 
of the date the physical taking of the Premises occurs.  Such right to 
terminate shall be exercised by written notice to Landlord within thirty (30) 
days after the date on which Tenant is first notified of the taking.  In the 
event this Lease is not terminated, the Rentable Area of the Project, the 
Rentable Area of the Project and Tenant's Pro Rata Share shall be 
appropriately adjusted.  In addition, Rent for any portion of the Premises so 
taken or condemned shall be abated during the unexpired term of this Lease 
effective when the physical taking of said portion of the Premises shall 
occur.  All compensation awarded for any such taking or condemnation, or sale 
proceeds in lieu thereof, shall be the property of Landlord, and Tenant shall 
have no claim thereto, the same being hereby expressly waived by Tenant, 
except for any portions of such award or proceeds which are specifically 
allocated by the condemning or purchasing party for the taking of or damage to 
trade fixtures of Tenant, which Tenant specifically reserves to itself.

XXII.  EVENTS OF DEFAULT.  The following events shall be deemed to be events 
of default under this Lease:

    A.  Tenant shall fail to pay when due any Base Rental, Additional Base 
Rental or other Rent under this Lease (hereinafter sometimes referred to as a 
"Monetary Default").

    B.  Any failure by Tenant (other than a Monetary Default) to comply with 
any term, provision or covenant of this Lease, which failure is not cured 
within ten (10) days after delivery to Tenant of notice of the occurrence of 
such failure, provided that if any such failure creates a hazardous condition, 
such failure must be cured immediately.

    C.  Tenant or any Guarantor shall become insolvent, or shall make a 
transfer in fraud of creditors, or shall commit an act of bankruptcy or shall 
make an assignment for the benefit of creditors, or Tenant or any Guarantor 
shall admit in writing its inability to pay its debts as they become due.

    D.  Tenant or any Guarantor shall file a petition under any section or 
chapter of the United States Bankruptcy Code, as amended, pertaining to 
bankruptcy, or under any similar law or statute of the United States or any 
State thereof, or Tenant or any Guarantor shall be adjudged bankrupt or 
insolvent in proceedings filed against Tenant or any Guarantor thereunder; or 
a petition or answer proposing the adjudication of Tenant or any Guarantor as 
a debtor or its reorganization under any present or future federal or state 
bankruptcy or similar law shall be filed in any court and such petition or 
answer shall not be discharged or denied within sixty (60) days after the 
filing thereof.

    E.  A receiver or trustee shall be appointed for all or substantially all 
of the assets of Tenant or any Guarantor or of the Premises or of any of 
Tenant's property located thereon in any proceeding brought by Tenant or any 
Guarantor, or any such receiver or trustee shall be appointed in any 
proceeding brought against Tenant or any Guarantor and shall not be discharged 
within sixty (60) days after such appointment or Tenant or such Guarantor 
shall consent to or acquiesce in such appointment.

    F.  The leasehold estate hereunder shall be taken on execution or other 
process of law or equity in any action against Tenant.

    G.  INTENTIONALLY OMITTED.

    H.  Tenant shall fail to take possession of and occupy the Premises within 
thirty (30) days following the Commencement Date and thereafter continuously 
conduct its operations in the Premises for the Permitted Use as set forth in 
Paragraph IV hereof.

       I.  The liquidation, termination, dissolution, forfeiture of right to 
do business or death of Tenant or any Guarantor.

                                     14


<PAGE>
    J.  Tenant shall be in default beyond any notice and cure period under any 
other lease with Landlord.

XXIII.  REMEDIES.

    A.  Upon the occurrence of any event or events of default under this 
Lease, whether enumerated in Article XXII or not, Landlord shall have the 
option to pursue any one or more of the following remedies without any notice 
(except as expressly prescribed herein) or demand whatsoever (and without 
limiting the generality of the foregoing, Tenant hereby specifically waives 
notice and demand for payment of Rent or other obligations and waives any and 
all other notices or demand requirements imposed by applicable law):

        1.  Terminate this Lease and Tenant's right to possession of the 
Premises by giving written notice to Tenant, and recover from Tenant an award 
of damages equal to the sum of the following:

            (a)  The Worth at the Time of Award of the unpaid Rent which had 
been earned at the time of termination;

            (b)  The Worth at the Time of Award of the amount by which the 
unpaid Rent which would have been earned after termination until the time of 
award exceeds the amount of such Rent loss that Tenant affirmatively proves 
could have been reasonably avoided;

            (c)  The Worth at the Time of Award of the amount by which the 
unpaid Rent for the balance of the Term after the time of award exceeds the 
amount of such Rent loss that Tenant affirmatively proves could be reasonably 
avoided;

            (d)  Any other amount necessary to compensate Landlord for all the 
detriment either proximately caused by Tenant's failure to perform Tenant's 
obligations under this Lease or which in the ordinary course of things would 
be likely to result therefrom; and

            (e)  All such other amounts in addition to or in lieu of the 
foregoing as may be permitted from time to time under applicable law.

            The "Worth at the Time of Award" of the amounts referred to in 
parts (a) and (b) above, shall be computed by allowing interest at the rate 
specified in Article V.B., and the "Worth at the Time of Award" of the amount 
referred to part (c), above, shall be computed by discounting such amount at 
the discount rate of the Federal Reserve Bank of San Francisco at the time of 
award plus one percent (1%);

        2.  Employ the remedy described in California Civil Code Section 
1951.4 (Landlord may continue this Lease in effect after Tenant's breach and 
abandonment and recover Rent as it becomes due, if Tenant has right to sublet 
or assign, subject only to reasonable limitations); or

        3.  Notwithstanding Landlord's exercise of the remedy described in 
California Civil Code Section 1951.4 in respect of an event or events of 
default, at such time thereafter as Landlord may elect in writing, to 
terminate this Lease and Tenant's right to possession of the Premises and 
recover an award of damages as provided above in part 1.

    B.  The subsequent acceptance of Rent hereunder by Landlord shall not be 
deemed to be a waiver of any preceding breach by Tenant of any term, covenant 
or condition of this Lease, other than the failure of Tenant to pay the 
particular Rent so accepted, regardless of Landlord's knowledge of such 
preceding breach at the time of acceptance of such Rent.  No waiver by 
Landlord of any breach hereof shall be effective unless such waiver is in 
writing and signed by Landlord.

    C.  TENANT HEREBY WAIVES ANY AND ALL RIGHTS CONFERRED BY SECTION 3275 OF 
THE CIVIL CODE OF CALIFORNIA AND BY SECTIONS 1174 (C) AND 1179 OF THE CODE OF 
CIVIL PROCEDURE OF CALIFORNIA AND ANY AND ALL OTHER LAWS AND RULES OF LAW 

                                     15


<PAGE>
FROM TIME TO TIME IN EFFECT DURING THE TERM PROVIDING THAT TENANT SHALL HAVE 
ANY RIGHT TO REDEEM, REINSTATE OR RESTORE THIS LEASE FOLLOWING ITS TERMINATION 
BY REASON OF TENANT'S BREACH.  TENANT ALSO HEREBY WAIVES, TO THE FULLEST 
EXTENT PERMITTED BY LAW, THE RIGHT TO TRIAL BY JURY IN ANY LITIGATION ARISING 
OUT OF OR RELATING TO THIS LEASE

    D.  No right or remedy herein conferred upon or reserved to Landlord is 
intended to be exclusive of any other right or remedy, and each and every 
right and remedy shall be cumulative and in addition to any other right or 
remedy given hereunder or now or hereafter existing by agreement, applicable 
law or in equity.  In addition to other remedies provided in this Lease, 
Landlord shall be entitled, to the extent permitted by applicable law, to 
injunctive relief, or to a decree compelling performance of any of the 
covenants, agreements, conditions or provisions of this Lease, or to any other 
remedy allowed to Landlord at law or in equity.  Forbearance by Landlord to 
enforce one or more of the remedies herein provided upon an event of default 
shall not be deemed or construed to constitute a waiver of such default.

    E.  This Article XXIII shall be enforceable to the maximum extent such 
enforcement is not prohibited by applicable law, and the unenforceability of 
any portion thereof shall not thereby render unenforceable any other portion.  

XXIV.  LIMITATION OF LIABILITY.  NOTWITHSTANDING ANYTHING TO THE CONTRARY 
CONTAINED IN THIS LEASE, THE LIABILITY OF LANDLORD (AND OF ANY SUCCESSOR 
LANDLORD HEREUNDER) TO TENANT SHALL BE LIMITED TO THE INTEREST OF LANDLORD IN 
THE BUILDING, AND TENANT AGREES TO LOOK SOLELY TO LANDLORD'S INTEREST IN THE 
BUILDING FOR THE RECOVERY OF ANY JUDGMENT OR AWARD AGAINST THE LANDLORD, IT 
BEING INTENDED THAT LANDLORD SHALL NOT BE PERSONALLY LIABLE FOR ANY JUDGMENT 
OR DEFICIENCY.  TENANT HEREBY COVENANTS THAT, PRIOR TO THE FILING OF ANY SUIT 
FOR AN ALLEGED DEFAULT BY LANDLORD HEREUNDER, IT SHALL GIVE LANDLORD AND ALL 
MORTGAGEES WHOM TENANT HAS BEEN NOTIFIED HOLD MORTGAGES OR DEED OF TRUST LIENS 
ON THE PROPERTY, BUILDING OR PREMISES NOTICE AND REASONABLE TIME TO CURE SUCH 
ALLEGED DEFAULT BY LANDLORD.  IN ADDITION, TENANT ACKNOWLEDGES THAT EQUITY 
OFFICE PROPERTIES, LLC AND EQUITY OFFICE HOLDINGS, LLC ARE ACTING SOLELY IN 
THEIR CAPACITY AS AGENT FOR LANDLORD AND SHALL NOT BE LIABLE FOR ANY 
OBLIGATIONS, LIABILITIES, LOSSES OR DAMAGES ARISING OUT OF OR IN CONNECTION 
WITH THIS LEASE, ALL OF WHICH ARE EXPRESSLY WAIVED BY TENANT.

XXV.  NO WAIVER.  Failure of Landlord to declare any default immediately upon 
its occurrence, or delay in taking any action in connection with an event of 
default shall not constitute a waiver of such default, nor shall it constitute 
an estoppel against Landlord, but Landlord shall have the right to declare the 
default at any time and take such action as is lawful or authorized under this 
Lease.  Failure by Landlord to enforce its rights with respect to any one 
default shall not constitute a waiver of its rights with respect to any 
subsequent default.  Receipt by Landlord of Tenant's keys to the Premises 
shall not constitute an acceptance or surrender of the Premises.

XXVI.  EVENT OF BANKRUPTCY.  In addition to, and in no way limiting the other 
remedies set forth herein, Landlord and Tenant agree that if Tenant ever 
becomes the subject of a voluntary or involuntary bankruptcy, reorganization, 
composition, or other similar type proceeding under the federal bankruptcy 
laws, as now enacted or hereinafter amended, then:

    A.  "Adequate protection" of Landlord's interest in the Premises pursuant 
to the provisions of Section 361 and 363 (or their successor sections) of the 
Bankruptcy Code, 11 U.S.C.  Section 101 et seq., (such Bankruptcy Code as 
amended from time to time being herein referred to as the "Bankruptcy Code"), 
prior to assumption and/or assignment of the Lease by Tenant shall include, 
but not be limited to all (or any part) of the following:

        1.  the continued payment by Tenant of the Base Rental and all other 
Rent due and owing hereunder and the performance of all other covenants and 
obligations hereunder by Tenant;

                                     16


<PAGE>
        2.  the hiring of security guards to protect the Premises if Tenant 
abandons and/or ceases operations; such obligation of Tenant only to be 
effective so long as Tenant remains in possession and control of the Premises 
to the exclusion of Landlord;

        3.  the furnishing of an additional/new security deposit by Tenant in 
the amount of three (3) times the then-current monthly Base Rental.

    B.  "Adequate assurance of future performance" by Tenant and/or any 
assignee of Tenant pursuant to Bankruptcy Code Section 365 will include (but 
not be limited to) payment of an additional/new Security Deposit in the amount 
of three (3) times the then-current Base Rental payable hereunder.

    C.  Any person or entity to which this Lease is assigned pursuant to the 
provisions of the Bankruptcy Code, shall be deemed without further act or deed 
to have assumed all of the obligations of Tenant arising under this Lease on 
and after the effective date of such assignment.  Any such assignee shall, 
upon demand by Landlord, execute and deliver to Landlord an instrument 
confirming such assumption of liability.

    D.  Notwithstanding anything in this Lease to the contrary, all amounts 
payable by Tenant to or on behalf of the Landlord under this Lease, whether or 
not expressly denominated as "Rent", shall constitute "rent" for the purposes 
of Section 502(b) (6) of the Bankruptcy Code.

    E.  If this Lease is assigned to any person or entity pursuant to the 
provisions of the Bankruptcy Code, any and all monies or other considerations 
payable or otherwise to be delivered to Landlord (including Base Rentals and 
other Rent hereunder), shall be and remain the exclusive property of Landlord 
and shall not constitute property of Tenant or of the bankruptcy estate of 
Tenant.  Any and all monies or other considerations constituting Landlord's 
property under the preceding sentence not paid or delivered to Landlord shall 
be held in trust by Tenant or Tenant's bankruptcy estate for the benefit of 
Landlord and shall be promptly paid to or turned over to Landlord.

    F.  If Tenant assumes this Lease and proposes to assign the same pursuant 
to the provisions of the Bankruptcy Code to any person or entity who shall 
have made a bona fide offer to accept an assignment of this Lease on terms 
acceptable to the Tenant, then notice of such proposed offer/assignment, 
setting forth 1. the name and address of such person or entity, 2. all of the 
terms and conditions of such offer, and 3. the adequate assurance to be 
provided Landlord to assure such person's or entity's future performance under 
the Lease, shall be given to Landlord by Tenant no later than twenty (20) days 
after receipt by Tenant, but in any event no later than ten (10) days prior to 
the date that Tenant shall make application to a court of competent 
jurisdiction for authority and approval to enter into such assumption and 
assignment, and Landlord shall thereupon have the prior right and option, to 
be exercised by notice to Tenant given at any time prior to the effective date 
of such proposed assignment, to accept an assignment of this Lease upon the 
same terms and conditions and for the same consideration, if any, as the bona 
fide offer made by such persons or entity, less any brokerage commission which 
may be payable out of the consideration to be paid by such person for the 
assignment of this Lease.

    G.  To the extent permitted by law, Landlord and Tenant agree that this 
Lease is a contract under which applicable law excuses Landlord from accepting 
performance from (or rendering performance to) any person or entity other than 
Tenant within the meaning of Sections 365(c) and 365(e) (2) of the Bankruptcy 
Code.

XXVII.  QUIET ENJOYMENT.  Tenant shall, and may peacefully have, hold, and 
enjoy the Premises, subject to the other terms of this Lease (including, 
without limitation, Article XXX hereof), provided that Tenant pays the Rent 
herein recited to be paid by Tenant and performs all of Tenant's covenants and 
agreements herein contained.  This covenant and any and all other covenants of 
Landlord shall be binding upon Landlord and its successors only during its or 
their respective periods of ownership of the Landlord's interest hereunder.

                                     17


<PAGE>
XXVIII.  RELOCATION.  Landlord, at its expense, shall be entitled to cause 
Tenant to relocate no more than one (1) time during the Lease Term from the 
Premises to comparable space containing approximately the same Rentable Area 
as the Premises (the "Relocation Space") within the Building or adjacent 
buildings within the Project at any time upon sixty (60) days prior written 
notice to Tenant, provided that the Relocation Space shall be located on or 
above the fifteenth (15th) floor of the One Market complex.  Landlord agrees 
to reimburse Tenant for all reasonable costs actually incurred in connection 
with the Relocation, including the cost of reprinting existing stationery and 
business cards, moving telephones, graphics and similar items of expense.  
Such a relocation shall not affect this Lease except that from and after the 
date of such relocation, "Premises" shall refer to the Relocation Space into 
which Tenant has been moved, rather than the original Premises as herein 
defined, and the Base Rental shall be adjusted so that immediately following 
such relocation the Base Rental for the Relocation Space per annum on a per 
square foot of Rentable Area basis shall be the same as the Base Rental per 
annum immediately prior to such relocation for the original Premises on a per 
square foot of Rentable Area basis.

XXIX.  HOLDING OVER.  In the event of holding over by Tenant after expiration 
or other termination of this Lease or in the event Tenant continues to occupy 
the Premises after the termination of Tenant's right of possession pursuant to 
Articles XXII and XXIII hereof, occupancy of the Premises subsequent to such 
termination or expiration shall be that of a tenancy at sufferance and in no 
event for month-to-month or year-to-year, but Tenant shall, throughout the 
entire holdover period, pay rent (on a per month basis without reduction for 
any partial months during any such holdover) equal to one hundred fifty 
percent (150%) of the sum of the Base Rental and Additional Base Rental due 
for the period immediately preceding such holding over, provided if the 
holding over continues for more than thirty (30) days, effective as of the 
thirty-first day, holdover rent shall increase to 200% of the sum of the Base 
Rental and Additional Base Rental due for the period immediately preceding 
such holding over, and further provided that in no event shall Base Rental and 
Additional Base Rental during the holdover period be less than the fair market 
rental for the Premises.  No holding over by Tenant or payments of money by 
Tenant to Landlord after the expiration of the term of this Lease shall be 
construed to extend the Lease Term or prevent Landlord from recovery of 
immediate possession of the Premises by summary proceedings or otherwise.  
Tenant shall be liable to Landlord for all damage, including any consequential 
damage, which Landlord may suffer by reason of any holding over by Tenant, and 
Tenant shall indemnify Landlord against any and all claims made by any other 
tenant or prospective tenant against Landlord for delay by Landlord in 
delivering possession of the Premises to such other tenant or prospective 
tenant.

XXX.  SUBORDINATION TO MORTGAGES.  Tenant accepts this Lease subject and 
subordinate to any mortgage, deed of trust, assignment of leases and rents, 
ground lease or other lien presently existing or hereafter arising upon the 
Premises, or upon the Building and/or the Project and to any renewals, 
modifications, refinancings and extensions thereof (any such mortgage, deed of 
trust, assignment of leases and rents, lease or other lien being hereinafter 
referred to as a "Mortgage", and the person or entity having the benefit of 
same being referred to hereinafter as a "Mortgagee"), but Tenant agrees that 
any such Mortgagee shall have the right at any time to subordinate such 
Mortgage to this Lease on such terms and subject to such conditions as such 
Mortgagee may deem appropriate in its discretion.  This clause shall be self-
operative and no further instrument of subordination shall be required.  
However, Landlord is hereby irrevocably vested with full power and authority 
to subordinate this Lease to any Mortgage, and Tenant agrees upon demand to 
execute such further instruments subordinating this Lease, acknowledging the 
subordination of this Lease or attorning to the holder of any such Mortgage as 
Landlord may request.  The terms of this Lease are subject to approval by the 
Landlord's existing lender(s) and any lender(s) who, at the time of the 
execution of this Lease, have committed or are considering committing to 
Landlord to make a loan secured by all or any portion of the Project, and such 
approval is a condition precedent to Landlord's obligations hereunder.  In the 
event that Tenant should fail to execute any subordination or other agreement 
required by this Article promptly as requested, Tenant hereby irrevocably 
constitutes Landlord as its attorney-in-fact to execute such instrument in 
Tenant's name, place and stead, it being agreed that such power is one coupled 

                                     18

with an interest in Landlord and is accordingly irrevocable.  If any person 
shall succeed to all or part of Landlord's interests in the Premises whether 
by purchase, foreclosure, deed in lieu of foreclosure, power of sale, 
termination of lease or otherwise, and if and as so requested or required by 
such successor-in-interest, Tenant shall, without charge, attorn to such 
successor-in-interest and if requested Tenant shall enter into a new lease 
with such successor-in-interest for the balance of the Term of the Lease then 
remaining on the same terms and conditions.  Said successor-in-interest shall 
not be bound by (i) any payment of Base Rental or Additional Base Rental for 
more than one (1) month in advance, except prepayments in the nature of 
security for the performance by Tenant of its obligations under the Lease or 
prepayments for estimated Basic Costs, or (ii) any material amendment or 
modification of the Lease made without the written consent of Mortgagee or 
such successor-in-interest except to the extent such amendment is entered into 
to document the exercise by Landlord or Tenant of any option or other rights 
specifically provided in the Lease.  Tenant agrees that it will from time to 
time upon request by Landlord and, within five days of the date of such 
request, execute and deliver to such persons as Landlord shall request an 
estoppel certificate or other similar statement in recordable form certifying 
that this Lease is unmodified and in full force and effect (or if there have 
been modifications, that the same is in full force and effect as so modified), 
stating the dates to which Rent and other charges payable under this Lease 
have been paid, stating that Landlord is not in default hereunder (or if 
Tenant alleges a default stating the nature of such alleged default) and 
further stating such other matters as Landlord shall reasonably require.

XXXI.  ATTORNEY'S FEES.  In the event that Landlord should retain counsel 
and/or institute any suit against Tenant for violation of or to enforce any of 
the covenants or conditions of this Lease, or should Tenant institute any suit 
against Landlord for violation of any of the covenants or conditions of this 
Lease, or should either party intervene in any suit in which the other is a 
party to enforce or protect its interest or rights hereunder, the prevailing 
party in any such suit shall be entitled to all of its costs, expenses and 
reasonable fees of its attorney(s) (if and to the extent permitted by law) in 
connection therewith.

XXXII.  NOTICE.  Whenever any demand, request, approval, consent or notice 
("Notice") shall or may be given to either of the parties by the other, each 
such Notice shall be in writing and shall be sent by registered or certified 
mail with return receipt requested, or sent by overnight courier service (such 
as Federal Express) at the respective addresses of the parties for notices as 
set forth in Section I.A.6. of this Lease, provided that if Tenant has vacated 
the Premises or is in default of this Lease Landlord may serve Notice by any 
manner permitted by Law.  Any Notice under this Lease delivered by registered 
or certified mail shall be deemed to have been given and effective on the 
earlier of (a) the third day following the day on which the same shall have 
been mailed with sufficient postage prepaid or (b) the delivery date indicated 
on the return receipt.  Notice sent by overnight courier service shall be 
deemed given and effective upon the day after such notice is delivered to or 
picked up by the overnight courier service.  Either party may, at any time, 
change its Notice Address by giving the other party Notice stating the change 
and setting forth the new address.

XXXIII.  LANDLORD'S LIEN.  INTENTIONALLY OMITTED.  The deletion of this 
Article XXXIII shall not be construed as a waiver of Landlord's lien rights as 
provided by law.

XXXIV.  EXCEPTED RIGHTS.  This Lease does not grant any rights to light or air 
over or about the Building.  Landlord specifically excepts and reserves to 
itself the use of any roofs, the exterior portions of the Premises, all rights 
to and the land and improvements below the improved floor level of the 
Premises, the improvements and air rights above the Premises and the 
improvements and air rights located outside the demising walls of the 
Premises, and such areas within the Premises as are required for installation 
of utility lines and other installations required to serve any occupants of 
the Building and the right to maintain and repair the same, and no rights with 
respect thereto are conferred upon Tenant unless otherwise specifically 
provided herein. Landlord further reserves to itself the right from time to 
time:  A. to change the Building's name or street address;  B. to install, fix 
and maintain signs on the exterior and interior of the Building;  C. to 
designate and approve window coverings;  D. to make any decorations, 
alterations,

<PAGE>
additions, improvements to the Building, or any part thereof (including the 
Premises) which Landlord shall desire, or deem necessary for the safety, 
protection, preservation or improvement of the Building, or as Landlord may be 
required to do by law;  E. to have access to the Premises to perform its 
duties and obligations and to exercise its rights under this Lease;  F. to 
retain at all times and to use pass-keys to all locks within and into the 
Premises;  G. to approve the weight, size, or location of heavy equipment, 
articles in and about the Premises;  H. to close or restrict access to the 
Building at all times other than Normal Business Hours subject to Tenant's 
right to admittance at all times under such regulations as Landlord may 
prescribe from time to time, or to close (temporarily or permanently) any of 
the entrances to the Building;  I. to change the arrangement and/or location 
of entrances of passageways, doors and doorways, corridors, elevators, stairs, 
toilets and public parts of the Building; and  J. to grant to anyone the 
exclusive right to conduct any business or undertaking in the Building.  
Landlord, in accordance with Article XII hereof, shall have the right to enter 
the Premises in connection with the exercise of any of the rights set forth 
herein and such entry into the Premises and the performance of any work 
therein shall not constitute a constructive eviction or entitle Tenant to any 
abatement or reduction of Rent by reason thereof.

XXXV.  SURRENDER OF PREMISES.  At the expiration or earlier termination of 
this Lease or Tenant's right of possession hereunder, Tenant shall quit and 
surrender the Premises to Landlord, broom clean, and in good order, condition 
and repair, ordinary wear and tear excepted.  If Tenant fails to remove any of 
Tenant's Property within one (1) day after the termination of this Lease or 
Tenant's right to possession hereunder, such Tenant's Property, or any portion 
thereof designated by Landlord, shall at Landlord's option, and without notice 
to Tenant, (a) be conclusively presumed to have been abandoned by Tenant and 
title to such items shall pass to Landlord, and/or (b) be removed and/or 
stored by Landlord at the risk, cost and expense of Tenant and Landlord shall 
in no event be responsible for the value, preservation or safekeeping thereof.  
Tenant shall pay Landlord, upon demand, any and all expenses caused by such 
removal and all storage charges against such property so long as the same 
shall be in the possession of Landlord or under the control of Landlord.

XXXVI.  MISCELLANEOUS.

    A.  If any term or provision of this Lease, or the application thereof to 
any person or circumstance shall, to any extent, be invalid or unenforceable, 
the remainder of this Lease, or the application of such term or provision to 
persons or circumstances other than those as to which it is held invalid or 
unenforceable, shall not be affected thereby, and each term and provision of 
this Lease shall be valid and enforced to the fullest extent permitted by law.

    B.  Tenant agrees not to record this Lease or any memorandum hereof 
without Landlord's prior written consent.

    C.  This Lease and the rights and obligations of the parties hereto shall 
be interpreted, construed, and enforced in accordance with the laws of the 
state in which the Building is located.

    D.  Events of "Force Majeure" shall include strikes, riots, acts of God, 
shortages of labor or materials, war, governmental law, regulations or 
restrictions and any other cause whatsoever that is beyond the control of 
Landlord.  Whenever a period of time is herein prescribed for the taking of 
any action by Landlord, Landlord shall not be liable or responsible for, and 
there shall be excluded from the computation of such period of time, any 
delays due to events of Force Majeure.

    E.  Landlord shall have the right to transfer and assign, in whole or in 
part, all of its rights and obligations hereunder and in the Building and 
Project referred to herein, and in such event and upon such transfer Landlord 
shall be released from any further obligations hereunder, and Tenant agrees to 
look solely to such successor in interest of Landlord for the performance of 
such obligations provided that Landlord and its successors, as the case may 
be, shall remain liable after their respective periods of ownership with 
respect to any sums due in connection with a breach or default that arose 
during such period of ownership.

                                     20


<PAGE>
    F.  Tenant hereby represents to Landlord that it has dealt directly with 
and only with the Broker as a broker in connection with this Lease.  Tenant 
agrees to indemnify and hold Landlord and the Landlord Related Parties 
harmless from all claims of any brokers claiming to have represented Tenant in 
connection with this Lease.

    G.  If there is more than one Tenant, or if the Tenant is comprised of 
more than one person or entity, the obligations hereunder imposed upon Tenant 
shall be joint and several obligations of all such parties.  All notices, 
payments, and agreements given or made by, with or to any one of such persons 
or entities shall be deemed to have been given or made by, with or to all of 
them.

    H.  In the event Tenant is a corporation (including any form of 
professional association), partnership (general or limited), or other form of 
organization other than an individual, then each individual executing or 
attesting this Lease on behalf of Tenant hereby covenants, warrants and 
represents:  1. that such individual is duly authorized to execute or attest 
and deliver this Lease on behalf of Tenant in accordance with the 
organizational documents of Tenant; 2. that this Lease is binding upon Tenant; 
3. that Tenant is duly organized and legally existing in the state of its 
organization, and is qualified to do business in the state in which the 
Premises is located; 4. that upon request, Tenant will provide Landlord with 
true and correct copies of all organizational documents of Tenant, and any 
amendments thereto; and 5. that the execution and delivery of this Lease by 
Tenant will not result in any breach of, or constitute a default under any 
mortgage, deed of trust, lease, loan, credit agreement, partnership agreement 
or other contract or instrument to which Tenant is a party or by which Tenant 
may be bound.  If Tenant is a corporation, Tenant will, prior to the 
Commencement Date, deliver to Landlord a copy of a resolution of Tenant's 
board of directors authorizing or ratifying the execution and delivery of this 
Lease, which resolution will be duly certified to Landlord's satisfaction by 
the secretary or assistant secretary of Tenant.

    I.  Tenant acknowledges that the financial capability of Tenant to perform 
its obligations hereunder is material to Landlord and that Landlord would not 
enter into this Lease but for its belief, based on its review of Tenant's 
financial statements, that Tenant is capable of performing such financial 
obligations.  Tenant hereby represents, warrants and certifies to Landlord 
that its financial statements previously furnished to Landlord were at the 
time given true and correct in all material respects and that there have been 
no material subsequent changes thereto as of the date of this Lease.  At any 
time during the Lease Term, Tenant shall provide Landlord, upon ten (10) days' 
prior written notice from Landlord, with a current financial statement and 
financial statements of the two (2) years prior to the current financial 
statement year.  Such statement shall be prepared in accordance with generally 
accepted accounting principles and, if such is the normal practice of Tenant, 
shall be audited by an independent certified public accountant.

    J.  Except as expressly otherwise herein provided, with respect to all 
required acts of Tenant, time is of the essence of this Lease.  This Lease 
shall create the relationship of Landlord and Tenant between the parties 
hereto, and no estate shall pass out of Landlord.  Tenant has only a usufruct, 
not subject to purchase or sale, which may not be assigned by Tenant except as 
expressly provided in this Lease.

    K.  This Lease and the covenants and conditions herein contained shall 
inure to the benefit of and be binding upon Landlord and Tenant and their 
respective permitted successors and assigns.

    L.  Notwithstanding anything to the contrary contained in this Lease, the 
expiration of the Lease Term, whether by lapse of time or otherwise, shall not 
relieve Tenant from Tenant's obligations accruing prior to the expiration of 
the Lease Term.

    M. The headings and titles to the paragraphs of this Lease are for 
convenience only and shall have no effect upon the construction or 
interpretation of any part hereof.

                                     21

                                 EXHIBIT B-2

                           PAYMENT OF BASIC COSTS

    This Exhibit is attached to and made a part of the Lease dated __________, 
1995, by and between ZML-ONE MARKET LIMITED PARTNERSHIP, A DELAWARE LIMITED 
PARTNERSHIP ("Landlord") by Equity Office Holdings, LLC, a Delaware limited 
liability company, its agent and TENERA, INC., A DELAWARE CORPORATION 
("Tenant") for space in the Building located at One Market, San Francisco, 
California, commonly known as Spear Tower.

    BASIC COST ADJUSTMENT.  During each calendar year, or portion thereof, 
falling within the Lease Term, Tenant shall pay to Landlord as Additional Base 
Rental hereunder the sum of (1) Tenant's Pro Rata Share of the amount, if any, 
by which Taxes (hereinafter defined) for the applicable calendar year exceed 
Taxes for the Base Year (hereinafter defined) plus (2) Tenant's Pro Rata Share 
of the amount, if any, by which Expenses (hereinafter defined) for the 
applicable calendar year exceed Expenses for the Base Year.  For purposes 
hereof, the "Base Year" shall mean the calendar year 1995.  Tenant's Pro Rata 
Share with respect to Taxes of increases in Taxes and Tenant's Pro Rata Share 
with respect to Expenses of increases in Expenses shall be computed separate 
and independent of each other prior to being added together to determine the 
"Excess."  In the event that Taxes and/or Expenses, as the case may be, in any 
calendar year decrease below the amount of Taxes or Expenses for the Base 
Year, Tenant's Pro Rata Share of Taxes and/or Expenses, as the case may be, 
for such calendar year shall be deemed to be $0, it being understood that 
Tenant shall not be entitled to any credit or offset if Taxes and/or Expenses 
decrease below the corresponding amount for the Base Year.  Prior to the 
Commencement Date and prior to January 1 of each calendar year during the 
Lease Term, or as soon thereafter as practical, Landlord shall make a good 
faith estimate of the Excess for the applicable calendar year.  On or before 
the first day of each month during such calendar year, Tenant shall pay 
Landlord, as Additional Base Rental, a monthly installment equal to one-
twelfth of Tenant's Pro Rata Share of Landlord's estimate of the Excess.  
Landlord shall have the right from time to time during any such calendar year 
to revise the estimate of the Excess for such year and provide Tenant with a 
revised statement therefor, and thereafter the amount Tenant shall pay each 
month shall be based upon such revised estimate.  If Landlord does not provide 
Tenant with an estimate of the Excess by January 1 of any calendar year, 
Tenant shall continue to pay a monthly installment based on the previous 
year's estimate until such time as Landlord provides Tenant with an estimate 
of the Excess for the current year.  Upon receipt of such current year's 
estimate, an adjustment shall be made for any month during the current year 
with respect to which Tenant paid monthly installments of Additional Base 
Rental based on the previous years estimate of the Excess.  Tenant shall pay 
Landlord for any underpayment upon demand.  Any overpayment shall, at 
Landlord's option, be refunded to Tenant or credited against the installment 
of Additional Base Rental due for the month immediately following the 
furnishing of such estimate.  Any amounts paid by Tenant based on any estimate 
shall be subject to adjustment pursuant to Paragraph A below, when actual 
Basic Costs are determined for such calendar year.

    A.  BASIC COSTS RECONCILIATION.  As soon as is practical following the end 
of each calendar year during the Lease Term, Landlord shall furnish to Tenant 
a statement of Landlord's actual Basic Costs and the actual Excess for the 
previous calendar year.  If for any calendar year the Additional Base Rental 
collected for the prior year, as a result of Landlord's estimate of Basic 
Costs, is in excess of Tenant's actual Pro Rata Share of the Excess for such 
prior year, then Landlord shall refund to Tenant any overpayment (or at 
Landlord's option, apply such amount against Additional Base Rental due or to 
become due hereunder).  Likewise, Tenant shall pay to Landlord, on demand, any 
underpayment with respect to the prior year, whether or not the Lease has 
terminated prior to receipt by Tenant of a statement for such underpayment, it 
being understood that this clause shall survive the expiration of the Lease.

had been at least ninety-five percent (95%) occupied during such year.

    E.  AUDIT RIGHT.  Tenant, at its sole cost and expense, shall have the

records relating to the Basic Costs for such year.  Landlord, within thirty 
(30) days after receipt of the Review Notice, shall make such books and 
records available to Tenant or Tenant's agent for its review at the office of 
the Building, provided that if Tenant retains an agent to review Landlord's 
books and records for any calendar year, such agent must be CPA firm licensed 
to do business in the state in which the Building is located.  If Tenant 
elects to review Landlord's books and records, within thirty (30) days after 
such books and records are made available to Tenant, Tenant shall have the 
right to give Landlord written notice stating in reasonable detail any 
objection to Landlord's statement of actual Basic Costs for such calendar 
year.  If Tenant fails to give Landlord written notice of objection within 
such thirty (30) day period or fails to provide Landlord with a Review Notice 
within the ninety (90) day period provided above, Tenant shall be deemed to 
have approved such statements in all respects.  Upon Landlord's receipt of a 
timely objection notice from Tenant, Landlord and Tenant shall work together 
in good faith to resolve the discrepancy between Landlord's statement and 
Tenant's review.  If Landlord and Tenant determine that Basic Costs are less 
than reported, Landlord shall provide Tenant with a credit against future 
Additional Base Rental in the amount of such overpayment.  Likewise, if 
Landlord and Tenant determine that Basic Costs are greater than reported, 
Tenant shall forthwith pay the amount of such underpayment to Landlord.  Any 
information obtained by Tenant pursuant to the provisions of the Section shall 
be treated as confidential.  Notwithstanding anything herein to the contrary, 
Tenant shall not be permitted to examine Landlord's books and records or to 
dispute any statement of Basic Costs unless Tenant has paid to Landlord (under 
protest, if Tenant so elects) the amount due 



<PAGE>
as shown on Landlord's statement of actual Basic Costs, said payment (albeit 
under protest) being a condition precedent to said examination and/or dispute.

    IN WITNESS WHEREOF, Landlord and Tenant have entered into this Lease as of 
the date first written above.

                                 WORK LETTER

    This Exhibit is attached to and made a part of the Lease dated __________, 
1995, by and between ZML-ONE MARKET LIMITED PARTNERSHIP, A DELAWARE LIMITED 
PARTNERSHIP ("Landlord") by Equity Office Holdings, LLC, a Delaware limited 
liability company, its agent and TENERA, INC., A DELAWARE CORPORATION 
("Tenant") for space in the Building located at One Market, San Francisco, 
California, commonly known as Spear Tower.

    INTENTIONALLY OMITTED, however, Tenant has inspected the Premises and 
agrees to accept the same "as is" without any agreements, representations, 
understandings or obligations on the part of Landlord to perform any 
alterations, repairs or improvements.  Any construction, alterations or 
improvements made to the Premises shall be made at Tenant's sole cost and 
expense.  Notwithstanding anything to the contrary, Landlord shall provide 
Tenant with an allowance ("Work Allowance") in an amount not exceed Fifty-Six 
Thousand Nine Hundred Four and NO/100 Dollars ($56,904.00) (i.e., $6.00 per 
rentable square foot of the Premises) (i) toward the cost of performing 
improvements to the Premises in preparation for Tenant's occupancy thereof or 
(ii) to be applied to Base Rental for the Premises beginning with the third 
(3rd) month of the Lease Term until the Work Allowance is reduced to $0.  All 
such improvements shall be performed in compliance with the terms and 
conditions of the Lease, including, without limitation, the prior approval of 
Landlord with respect to the improvements to be performed and the contractors 
to be retained to perform such improvements.  The Work Allowance shall be paid 
to Tenant following receipt of the following documentation: full and final 
waivers of liens from the general contractor and the subcontractors retained 
by Tenant in an amount equal to the portion of the Work Allowance to be 
disbursed, completion certificates from Tenant, the general contractor and 
Tenant's architect, a sworn contractor's affidavit from the general contractor 
and a request to disburse from Tenant containing an approval by Tenant of the 
work done, receipted bills covering all labor and materials expended and used 
in connection with the improvements.  If Tenant has not previously paid the 
general contractor for the cost of the improvements, Landlord, at its option, 
may pay the Work Allowance directly to the order of the general contractor 
that performed the improvements or to the joint order of the general 
contractor and all included subcontractors.  Notwithstanding anything herein 
to the contrary, Landlord shall not be obligated to disburse any portion of 
the Work Allowance during the continuance of an uncured default under the 
Lease, and Landlord's obligation to disburse shall only resume when and if 
such default is cured.  The Work Allowance may only be used for the cost of 
labor, material and contractors fees for the improvements to the Premises and 
the cost of preparing plans and drawings in connection therewith.  In no event 
shall the Work Allowance be used for the purchase of equipment, furniture and 
other items of personal property of Tenant.

                                  EXHIBIT D

                       BUILDING RULES AND REGULATIONS

    This Exhibit is attached to and made a part of the Lease dated __________, 
1995, by and between ZML-ONE MARKET LIMITED PARTNERSHIP, A DELAWARE LIMITED 
PARTNERSHIP ("Landlord") by Equity Office Holdings, LLC, a Delaware limited 
liability company, its agent and TENERA, INC., A DELAWARE CORPORATION 
("Tenant") for space in the Building located at One Market, San Francisco, 
California, commonly known as Spear Tower.

    The following rules and regulations shall apply, where applicable, to the 
Premises, the Building, the parking garage associated therewith (if any), the 
Project and the appurtenances thereto:

    1.  Sidewalks, doorways, vestibules, halls, stairways and other similar 
areas shall not be obstructed by Tenant or used by Tenant for any purpose 
other than ingress and egress to and from the Premises.  No rubbish, litter, 
trash, or material of any nature shall be placed, emptied, or thrown in those 
areas.  At no time shall Tenant permit Tenant's employees to loiter in common 
areas or elsewhere in or about the Building or Project.

    2.  Plumbing fixtures and appliances shall be used only for the purposes 
for which designed, and no sweepings, rubbish, rags or other unsuitable 
material shall be thrown or placed therein.  Damage resulting to any such 
fixtures or appliances from misuse by Tenant or its agents, employees or 
invitees, shall be paid for by Tenant, and Landlord shall not in any case be 
responsible therefor.

    3.  No signs, advertisements or notices shall be painted or affixed on or 
to any windows, doors or other parts of the Building, except those of such 
color, size, style and in such places as shall be first approved in writing by 
Landlord.  No nails, hooks or screws shall be driven or inserted into any part

    6.  Tenant will refer to Landlord for Landlord's supervision, approval, 
and control all contractors, contractor's representatives, and installation 
technicians rendering any service to Tenant, before performance of any 
contractual service.  Such supervisory action by Landlord shall not render 
Landlord responsible for any work performed for Tenant.  This provision shall 
apply to all work performed in the Building, including but not limited to the

responsible for complying with all applicable laws, codes and ordinances 
pursuant to which said work shall be performed.

or dispatch or receipt by Tenant of any merchandise or materials which require 
the use of elevators, stairways, lobby areas, or loading dock areas, shall be 
restricted to hours designated by Landlord.  Tenant must seek Landlord's prior 
approval by providing in writing a detailed listing of any such activity.  If 
approved by Landlord, such activity shall be under the supervision of Landlord 
and performed in the manner stated by Landlord.  Landlord may prohibit any 
article, equipment or any other item from being brought into the Building.  
Tenant is to assume all risk for damage to articles moved and injury to any 
persons resulting from such activity.  If any equipment, property, and/or 
personnel of Landlord or any of any other tenant is damaged or injured as a 
result of or in connection with such activity, Tenant shall be solely liable 
for any and all damage or loss resulting therefrom.



<PAGE>
    8.  Landlord shall have the power to prescribe the weight and position of 
safes and other heavy equipment or items, which in all cases shall not in the 
opinion of Landlord exceed acceptable floor loading and weight distribution 
requirements.  All damage done to the Building by the installation or removal 
of any property of Tenant, or done by Tenant's property while in the Building, 
shall be repaired at the expense of Tenant.

    9.  Corridor doors, when not in use, shall be kept closed.

    10.  Tenant shall not: (i) make or permit any improper, objectionable or 
unpleasant noises or odors in the Building, or otherwise interfere in any way 
with other tenants or persons having business with them; (ii) solicit business 
or distribute, or cause to be distributed, in any portion of the Building any 
handbills, promotional materials or other advertising; or (iii) conduct or 
permit any other activities in the Building that might constitute a nuisance.

    11.  No animals, except seeing eye dogs, shall be brought into or kept in, 
on or about the Premises.

    12.  No inflammable, explosive or dangerous fluid or substance shall be 
used or kept by Tenant in the Premises or Building.  Tenant shall not, without 
Landlord's prior written consent, use, store, install, spill, remove, release 
or dispose of within or about the Premises or any other portion of the 
Property, any asbestos-containing materials or any solid, liquid or gaseous 
material now or hereafter considered toxic or hazardous under the provisions 
of 42 U.S.C. Section 9601 et seq. or any other applicable environmental law 
which may now or hereafter be in effect.  If Landlord does give written 
consent to Tenant pursuant to the foregoing sentence, Tenant shall comply with 
all applicable laws, rules and regulations pertaining to and governing such 
use by Tenant, and shall remain liable for all costs of cleanup or removal in 
connection therewith.

    13.  Tenant shall not use or occupy the Premises in any manner or for any 
purpose which would injure the reputation or impair the present or future 
value of the Premises or the Building; without limiting the foregoing, Tenant 
shall not use or permit the Premises or any portion thereof to be used for 
lodging, sleeping or for any illegal purpose.

    14.  Tenant shall not take any action which would violate Landlord's labor 
contracts affecting the Building or which would cause any work stoppage, 
picketing, labor disruption or dispute, or any interference with the business 
of Landlord or any other tenant or occupant of the Building or with the rights 
and privileges of any person lawfully in the Building.  Tenant shall take any 
actions necessary to resolve any such work stoppage, picketing, labor 
disruption, dispute or interference and shall have pickets removed and, at the 
request of Landlord, immediately terminate at any time any construction work 
being performed in the Premises giving rise to such labor problems, until such 
time as Landlord shall have given its written consent for the resumption of 
such work.  Tenant shall have no claim for damages of any nature against 
Landlord or any of the Landlord Related Parties in connection therewith, nor 
shall the date of the commencement of the Term be extended as a result 
thereof.

    15.  Tenant shall utilize the termite and pest extermination service 
designated by Landlord to control termites and pests in the Premises.  Tenant 
shall bear the cost and expense of such extermination services, provided that 
Tenant shall not be obligated to pay more for its participation in such 
termite and pest extermination services than the prevailing competitive rates 
charged by reputable independent termite and pest control exterminators for 
the same service on a direct and individual basis.

    16.  Tenant shall not install, operate or maintain in the Premises or in 
any other area of the Building, any electrical equipment which does not bear 
the U/L (Underwriters Laboratories) seal of approval, or which would overload 
the electrical system or any part thereof beyond its capacity for proper, 
efficient and safe operation as determined by Landlord, taking into 
consideration the overall electrical system and the present and future 
requirements therefor in the Building.  Tenant shall not furnish any cooling 
or heating to the Premises, including, without limitation the use of any 
electronic or gas heating devices, without Landlord's prior written consent.

    17.  Tenant shall not operate or permit to be operated on the Premises any 
coin or token operated vending machine or similar device (including, without 



<PAGE>
limitation, telephones, lockers, toilets, scales, amusement devices and 
machines for sale of beverages, foods, candy, cigarettes or other goods), 
except for those vending machines or similar devices which are for the sole 
and exclusive use of Tenant's employees, and then only if such operation does 
not violate the lease of any other tenant of the Building.

    18.  Bicycles and other vehicles are not permitted inside or on the 
walkways outside the Building, except in those areas specifically designated 
by Landlord for such purposes.

    19.  Landlord may from time to time adopt appropriate systems and 
procedures for the security or safety of the Building, its occupants, entry 
and use, or its contents.  Tenant, Tenant's agents, employees, contractors, 
guests and invitees shall comply with Landlord's reasonable requirements 
relative thereto.

    20.  Landlord shall have the right to prohibit the use of the name of the 
Building or any other publicity by Tenant that in Landlord's opinion may tend 
to impair the reputation of the Building or its desirability for Landlord or 
other tenants.  Upon written notice from Landlord, Tenant will refrain from 
and/or discontinue such publicity immediately.

    21.  Tenant shall carry out Tenant's permitted repair, maintenance, 
alterations, and improvements in the Premises only during times agreed to in 
advance by Landlord and in a manner which will not interfere with the rights 
of other tenants in the Building.

    22.  Canvassing, soliciting, and peddling in or about the Building is 
prohibited.  Tenant shall cooperate and use its best efforts to prevent the 
same.

    23.  At no time shall Tenant permit or shall Tenant's agents, employees, 
contractors, guests, or invitees smoke in any common area of the Building, 
unless such common area has been declared a designated smoking area by 
Landlord.

    24.  Tenant shall observe Landlord's rules with respect to maintaining 
standard window coverings at all windows in the Premises so that the Building 
presents a uniform exterior appearance.  Tenant shall ensure that to the 
extent reasonably practicable, window coverings are closed on all windows in 
the Premises while they are exposed to the direct rays of the sun.

    25.  All deliveries to or from the Premises shall be made only at such 
times, in the areas and through the entrances and exits designated for such 
purposes by Landlord.  Tenant shall not permit the process of receiving 
deliveries to or from the Premises outside of said areas or in a manner which 
may interfere with the use by any other tenant of its premises or of any 
common areas, any pedestrian use of such area, or any use which is 
inconsistent with good business practice.



<PAGE>
    26.  The work of cleaning personnel shall not be hindered by Tenant after 
5:30 p.m., and such cleaning work may be done at any time when the offices are 
vacant.  Windows, doors and fixtures may be cleaned at any time.  Tenant shall 
provide adequate waste and rubbish receptacles necessary to prevent 
unreasonable hardship to Landlord regarding cleaning service.

    IN WITNESS WHEREOF, Landlord and Tenant have entered into this Lease as of 
the date first written above.

                                  EXHIBIT E

                              ADDITIONAL TERMS

    This Exhibit is attached to and made a part of the Lease dated __________, 
1995, by and between ZML-ONE MARKET LIMITED PARTNERSHIP, A DELAWARE LIMITED 
PARTNERSHIP ("Landlord") by Equity Office Holdings, LLC, a Delaware limited 
liability company, its agent and TENERA, INC., A DELAWARE CORPORATION 
("Tenant") for space in the Building located at One Market, San Francisco, 
California, commonly known as Spear Tower.

(I)  RENEWAL OPTION

    A.  Tenant shall have the right to extend the Lease Term for one 
additional period of three (3) years commencing on the day following the 
Termination Date of the initial Lease Term and ending on the last day of the 
thirty-sixth (36th) month anniversary of the Termination Date (the "Renewal 
Term"), if:

        1.  Landlord receives notice of exercise ("Initial Renewal Notice") 
not less than nine (9) full calendar months prior to the expiration of the 
initial Lease Term and not more than twelve (12) full calendar months prior to 
the expiration of the initial Lease Term; and

        2.  Tenant is not in default under the Lease beyond any applicable 
cure periods at the time that Tenant delivers its Initial Renewal Notice or at 
the time Tenant delivers its Binding Renewal Notice; and

        3.  No part of the Premises is sublet at the time that Tenant delivers 
its Initial Renewal Notice or at the time Tenant delivers its Binding Renewal 
Notice; and

        4.  The Lease has not been assigned prior to the date that Tenant 
delivers its Initial Renewal Notice or prior to the date Tenant delivers its 
Binding Renewal Notice; and

        5.  Tenant executes and returns the Renewal Amendment (hereinafter 
defined) within fifteen (15) days after its submission to Tenant.

    B.  The initial Base Rental rate per rentable square foot for the Premises 
during the Renewal Term shall equal the Prevailing Market (hereinafter 
defined) rate per rentable square foot for the Premises.

    C.  Tenant shall pay Additional Base Rental (i.e. Basic Costs) for the 
Premises during the Renewal Term in accordance with Exhibit B-2 of the Lease.

    D.  Within thirty (30) days after receipt of Tenant's Initial Renewal 
Notice, Landlord shall advise Tenant of the applicable Base Rental rate for 
the Premises for the Renewal Term.  Tenant, within fifteen (15) days after the 
date on which Landlord advises Tenant of the applicable Base Rental rate for 
the Renewal Term, shall either (i) give Landlord final binding written notice 
("Binding Notice") of Tenant's exercise of its option, or (ii) if Tenant 
disagrees with Landlord's determination, provide Landlord with written notice 
of rejection (the "Rejection Notice").  If Tenant fails to provide Landlord 
with either a Binding Notice or Rejection Notice within such fifteen (15) day 
period, Tenant's Renewal Option shall be null and void and of no further force 
and effect.  If Tenant provides Landlord with a Binding Notice, Landlord and 
Tenant shall enter into the Renewal Amendment upon the terms and conditions 
set forth herein.  If Tenant provides Landlord with a Rejection Notice, 
Landlord and Tenant shall work together in good faith to agree upon the 
Prevailing Market Base Rental rate for the Premises during the Renewal Term.  
Upon agreement Tenant shall provide Landlord with Binding Notice and Landlord 
and Tenant shall enter into the Renewal Amendment in accordance with the terms 
and conditions hereof.  Notwithstanding the foregoing, if Landlord and Tenant 
are unable to agree upon the Prevailing Market Base Rental rate for the 
Premises within thirty (30) days after the date on which Tenant provides 
Landlord with a Rejection Notice, Tenant's Renewal Option shall be null and 
void and of no force and effect.

    E.  If Tenant is entitled to and properly exercises its Renewal Option, 
Landlord shall prepare an amendment (the "Renewal Amendment") to reflect 
changes in the Base Rental, Lease Term, Termination Date and other appropriate 
terms.  The Renewal Amendment shall be:



<PAGE>
        1.  sent to Tenant within a reasonable time after receipt of the 
Renewal Notice; and

        2.  executed by Tenant and returned to Landlord in accordance with 
paragraph A.5. above.

    F.  For purposes hereof, "Prevailing Market" shall mean the arms length 
fair market annual rental rate per rentable square foot under renewal leases 
and amendments entered into on or about the date on which the Prevailing 
Market is being determined hereunder for space comparable to the Premises in 
the Building and office buildings comparable to the Building in the San 
Francisco bay area.  The determination of Prevailing Market shall take into 
account any material economic differences between the terms of this Lease and 
any comparison lease, such as rent abatements, construction costs and other 
concessions and the manner, if any, in which the landlord under any such lease 
is reimbursed for operating expenses and taxes.  The determination of 
Prevailing Market shall also take into consideration any reasonably 
anticipated changes in the Prevailing Market rate from the time such 
Prevailing Market rate is being determined and the time such Prevailing Market 
rate will become effective under this Lease.

    IN WITNESS WHEREOF, Landlord and Tenant have entered into this Lease as of 
the date first written above.
