     When used herein, the words "believes," "expects," "anticipates," "intends"
and similar expressions are intended to identify forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933, as amended (the
"Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as
amended, regarding events, conditions and financial trends that may affect the
Company's future plan of operation, business strategy, results of operations and
financial position.  Forward-looking statements are not guarantees of future
performance and are subject to risks and uncertainties.  Actual results may
differ materially from those included within the forward-looking statements as a
result of various factors, including, but not limited to, those described below
under the heading "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the risk factors identified in the Company's
Registration Statement on Form S-11 (No. 333-23545) initially filed with the
Securities and Exchange Commission on March 18, 1997.  The Company disclaims any
obligation to update any such factors or to announce publicly the result of any
revisions to any of the forward-looking statements.

ITEM 1. BUSINESS. 

BACKGROUND AND FORMATION.  

     Alexandria Real Estate Equities, Inc. ("Alexandria" and, together with its
subsidiaries, the "Company"), a Maryland corporation, is a real estate
investment trust ("REIT") engaged primarily in the acquisition, management,
expansion and selective development of high quality, strategically located
properties containing office and laboratory space designed and improved for
lease principally to pharmaceutical, biotechnology, diagnostic and personal care
products companies, major scientific research institutions and related
government agencies (collectively, the "Life Science Industry").  Properties
leased to tenants in the Life Science Industry typically consist of suburban
office buildings containing scientific research and development laboratories and
other improvements that are generic to tenants operating in the Life Science
Industry (such properties, "Life Science Facilities"). As of December 31, 1997,
the Company owned 22 Life Science Facilities (the "Properties") and two parcels
of vacant land, aggregating approximately 4.2 acres, adjacent to the Company's
3535 and 3565 General Atomics Court Properties in the Torrey Pines area of San
Diego, California.

     FORMATION.  In connection with the formation of Alexandria in October 1994,
Health Science Properties Holding Corporation ("Holdings"), a Maryland
corporation formed in September 1993 and capitalized in January 1994,
contributed substantially all of its assets and liabilities (other than certain
outstanding unsecured notes) to Alexandria in exchange for all of the then
issued and outstanding shares of common stock of Alexandria, par value $.01 per
share (the "Common Stock").  Holdings was the sole holder of the Common Stock
until June 2, 1997, when Alexandria completed its initial public offering (the
"Offering") of 6,750,000 shares of Common Stock.  On June 26, 1997, Alexandria
issued an additional 1,012,500 shares of Common Stock pursuant to the exercise
of the over-allotment option granted to the underwriters in connection with the
Offering.  

     THE OFFERING AND RECENT DEVELOPMENTS.

     THE OFFERING. Each of the following transactions occurred in connection
     with the Offering:

- -    The 27,500 outstanding shares of Series V Preferred Stock of Alexandria,
     issued in 1996 in a series of transactions to raise additional equity
     capital, were converted into 1,659,239 shares of Common Stock.

- -    The Company acquired 100% of the membership interests in ARE Acquisitions,
     LLC, a Delaware limited liability company (the "Acquisition LLC"), thereby
     acquiring three of the Properties, for an aggregate purchase price of
     approximately $58.8 million.

- -    The Company repaid approximately $77.7 million of its then-existing
     mortgage indebtedness with a portion of the net proceeds of the Offering 
     and the net proceeds of (i) an $8.5 million mortgage loan on the 
     Property located at 1431 Harbor Bay


                                         1
<PAGE>


     Parkway and (ii) a $6.9 million mortgage loan on the Property located at
     1102 and 1124 Columbia Street.  The Company subsequently repaid the
     mortgage loan on 1102 and 1124 Columbia Street in November 1997.

     ACQUISITIONS. Since December 31, 1997 (through March 27, 1998), the 
Company has acquired 11 additional Life Science Facilities containing an 
aggregate of 927,000 rentable square feet for an aggregate purchase price of 
approximately $110 million and made a $6 million loan secured by real estate 
related to one of these Life Science Facilities.  Of these amounts, $103 
million was funded through draws on the Company's unsecured line of credit, 
approximately $13 million through the assumption of existing debt and the 
remainder with working capital.  The recent acquisitions were in California 
(in the San Diego and San Francisco Bay areas), Seattle, Washington, suburban 
Maryland, Boston/Cambridge, Massachusetts, Raleigh/Durham, North Carolina and 
the New York/New Jersey and suburban Philadelphia areas.  

     STRUCTURE.  The Company is in the process of modifying its existing 
corporate structure to facilitate its operation as an umbrella partnership or 
"UPREIT."  The Company has formed an operating partnership (the "Operating 
Partnership") through which the Company expects to conduct substantially all 
of its operations. The Company believes that the UPREIT structure will 
enhance its acquisition activities by providing an additional source of 
acquisition consideration.  Initially, however, the Company will own all of 
the interests in the Operating Partnership ("OP Units").

BUSINESS AND GROWTH STRATEGY.  

     As of December 31, 1997, the Company owned 22 Properties containing 
approximately 1.75  million rentable square feet of office and laboratory 
space located in California (in the San Diego and San Francisco Bay areas), 
Seattle, Washington and suburban Washington, D.C. (including Maryland and 
Virginia).  The Company also owned two parcels of vacant land aggregating 
approximately 4.2 acres in San Diego, California.  The Company focuses its 
operations and acquisition activities principally in these markets, as well 
as in certain other markets, including Boston/Cambridge, Massachusetts, 
Raleigh/Durham, North Carolina and the New York/New Jersey and suburban 
Philadelphia areas.  See "--Recent Developments."  The Company's tenant base 
is broad and diverse within the Life Science Industry and reflects the 
Company's focus on regional, national and international tenants with 
substantial financial and operational resources. For a detailed description 
of the Properties and tenants, see "Item 2. Properties."  The Company is led 
by a senior management team with extensive experience in both the real estate 
and Life Science industries and is supported by a highly experienced board of 
directors.  

     The Company seeks to maximize growth in funds from operations ("FFO") 
and cash available for distribution to stockholders through effective 
management, operation, acquisition, expansion and selective development of 
Life Science Facilities.  See "Item 7.  Management's Discussion and Analysis 
of Financial Condition and Results of Operations--Funds from Operations" for 
a complete discussion of how the Company computes and views FFO as well as a 
discussion of other measures of cash flow.  In particular, the Company seeks 
to increase FFO and cash available for distribution per share by (i) 
acquiring high quality Life Science Facilities at attractive returns in its 
target markets; (ii) realizing contractual rental rate escalations; (iii) 
retenanting and releasing space within its portfolio at higher rental rates, 
and with minimal tenant improvement costs; (iv) expanding existing Properties 
or converting existing office space to generic laboratory space that can be 
leased at higher rental rates; (v) selectively developing properties on a 
retrofit or build-to-suit basis; and (vi) continuing to implement effective 
cost control measures, including pass-through provisions in tenant leases for 
operating expenses and certain capital expenditures.

                                         2
<PAGE>

     ACQUISITIONS.  The Company seeks to identify and acquire high quality Life
Science Facilities in its target markets.  Critical evaluation of prospective
property acquisitions is an essential component of the Company's acquisition
strategy.  When evaluating acquisition opportunities, the Company assesses a
full range of matters  relating to the properties, including the quality of the
tenants, the condition and capacity of building infrastructure, the quality and
generic characteristics of laboratory facilities and the physical condition of
the shell structure and common area improvements.  Management also considers
opportunities available for leasing vacant space and for retenanting occupied
space. 

     INTERNAL GROWTH.  The Company seeks to achieve internal growth from several
sources.  The Company seeks to (i) include rental rate escalation provisions in
its leases; (ii) acquire undervalued or underperforming properties where it can
improve investment returns through releasing of vacant space and replacement of
existing tenants with new tenants at higher rental rates; (iii) achieve higher
rental rates as existing leases expire; and (iv) expand existing facilities that
are fully leased and/or convert existing office space to higher rent generic
laboratory space.  The Company's ability to negotiate contractual rent
escalations in future leases and to achieve increases in rental rates will
depend upon market conditions and demand for Life Science Facilities at the time
such leases are negotiated and such increases are proposed.

     DEVELOPMENT.  The Company intends to emphasize acquisitions over 
development in pursuing its growth objectives.  However, the Company plans to 
pursue selective build-to-suit and retrofit development projects where it 
expects to achieve investment returns that will equal or exceed its returns 
on acquisitions.  The Company generally intends to undertake build-to-suit 
and retrofit projects only if the Company's investment in infrastructure will 
be substantially generic in nature and not tenant specific.

     FINANCING/WORKING CAPITAL.  The Company believes that cash provided by 
operations and its unsecured line of credit will be sufficient to fund its 
working capital requirements.  The Company generally expects to finance 
future acquisitions initially through the Company's unsecured line of credit 
and then to refinance such indebtedness with additional equity or debt 
capital.  The Company also may issue Common Stock, OP Units or interests in 
other subsidiaries as consideration for acquisitions.  See "Item 7. 
Management's Discussion and Analysis of Financial Condition and Results of 
Operations--Liquidity and Capital Resources" for a complete discussion of the 
Company's unsecured line of credit and other outstanding indebtedness.  

COMPETITION

     Management believes that the Company is the only publicly traded entity
focusing primarily on the acquisition, management, expansion and selective
development of Life Science Facilities.  However, various entities, including
insurance companies, pension and investment funds, partnerships, developers,
investment companies and other REITs invest in Life Science Facilities and
therefore compete for investment opportunities with the Company.  Many of these
entities have substantially greater financial resources than the Company and may
be able to accept more risk than the Company can prudently manage, including
risks with respect to the creditworthiness of a tenant or the geographic
proximity of its investments.  Competition from these entities may reduce the
number of suitable investment opportunities offered to the Company or increase
the bargaining power of property owners seeking to sell. 


                                         3
<PAGE>

GOVERNMENT REGULATION

     The Company and the Properties are subject to various federal, state and
local regulatory requirements, including local building codes, environmental and
other similar regulations.  The Company believes that the Properties are in
substantial compliance with all applicable building code and related
regulations.

     ENVIRONMENTAL MATTERS.  Under various federal, state and local
environmental laws and regulations, a current or previous owner or operator of
real estate, as well as certain other parties, may be required to investigate
and remediate the effects of hazardous or toxic substances or petroleum product
releases on, under, in or from such property, and may be held liable to a
governmental entity or to third parties for investigation and cleanup costs and
certain damages resulting from such releases.  Such laws and regulations
typically impose responsibility and liability without regard to whether such
person knew of or caused the releases, and the liability under such laws and
regulations has been interpreted to be joint and several, unless the harm is
divisible and there is a reasonable basis for allocation of responsibility.  The
cost of investigating and remediating such contamination may be substantial, and
the presence of such contamination, or the failure to properly remediate it, may
adversely affect the owner's ability to sell or rent such property or to borrow
using such property as collateral.  In addition, the owner of a site may be
subject to governmental fines and common law claims by third parties seeking to
recover damages and costs resulting from such contamination.  

     Certain other federal, state and local laws and regulations govern the
management and disposal of asbestos containing materials ("ACMs").  Such laws
and regulations may impose liability for the release of ACMs and may provide for
third parties to seek recovery from owners or operators of such property for
personal injury associated with ACMs.  In connection with the ownership and
operation of its properties, the Company may be potentially liable for such
costs.  ACMs have been detected at certain of the Properties, but are not
expected to result in material environmental costs or liabilities to the
Company.  Federal, state and local laws and regulations also require the removal
or upgrading of certain underground storage tanks and regulate the discharge of
storm water, wastewater and any water pollutants, the emission of air
pollutants, the generation, management and disposal of hazardous or toxic
chemicals, substances or wastes, and workplace health and safety.  
 
     Life Science Industry tenants, including certain of the Company's tenants,
engage in various research and development activities involving the controlled
use of hazardous materials, chemicals, biological and radioactive compounds. 
Although the Company believes that the tenants' activities involving such
materials comply in all material respects with applicable laws and regulations,
the risk of contamination or injury from these materials cannot be completely
eliminated.  In the event of such contamination or injury, the Company could be
held liable for any damages that result, and any such liability could exceed the
Company's resources and its environmental remediation coverage. 

     All of the Properties have been, and it is contemplated that all future
acquisitions will be, subjected to a Phase I or similar environmental assessment
(which generally includes a site inspection, interviews and a records review,
but no subsurface sampling).  These assessments and certain follow-up
investigations (including, as appropriate, asbestos, radon and lead surveys,
additional public records review, subsurface sampling and other testing) of the
Properties have not revealed any environmental liability that the Company
believes would have a material adverse effect on the Company's business or
results of operations.  Nevertheless, it is possible that the assessments on the
Properties have not revealed, or that the assessments on future acquisitions
will not reveal, all environmental liabilities and that there may be material
environmental liabilities of which the Company is unaware.  

     The Company believes that the Properties currently are in compliance in all
material respects with applicable environmental laws. 

     AMERICANS WITH DISABILITIES ACT.  Under the Americans with Disabilities Act
of 1990 (the "ADA"), places of public accommodation and/or commercial facilities
are required to meet certain federal requirements related to access and use by
disabled persons.  Although management of the Company believes that the
Properties are substantially in compliance with the present requirements of the
ADA, the Company may incur additional costs in connection with such


                                         4
<PAGE>

compliance in the future.  In addition, a number of additional federal, state 
and local laws and regulations exist that may require modifications to the 
Company's properties, or affect certain future renovations thereof, with respect
to access by disabled persons.  Non-compliance with the ADA could result in the
imposition of fines or an award of damages to private litigants, and also could
result in an order to correct any non-complying feature.  Under certain of the 
Company's leases, the tenant is responsible for ensuring that the property 
complies with all laws and regulations, including the ADA.  Notwithstanding the
foregoing, the Company may be required to make substantial capital expenditures 
to comply with this law.  In addition, provisions of the ADA may impose 
limitations or restrictions on the completion of certain renovations and thus 
may limit the overall returns on the Company's investments.  

FINANCIAL INFORMATION REGARDING INDUSTRY SEGMENTS AND OPERATIONS.  

     The Company currently is involved only in the real estate industry 
segment within the United States; the Company has no foreign operations.  
Accordingly, all financial statements contained herein relate to such 
industry segment.  See "Item 2. Properties" and "Item 8. Financial Statements 
and Supplementary Data" for detailed financial information regarding the 
Company's business.

EMPLOYEES 

     As of December 31, 1997, the Company had 18 full-time employees. 

ITEM 2. PROPERTIES. 

GENERAL.

     The Properties range in size from approximately 30,000 to 250,000 square
feet, are built to accommodate single or multiple tenants and are generally one
or two story concrete tilt-up or block and steel frame structures.  The
exteriors typically resemble traditional suburban office properties, but
interior infrastructures are designed to accommodate the needs of Life Science
Industry tenants.  Such improvements typically are generic to Life Science
Industry tenants rather than specific to a particular tenant.  As a result,
management believes that the improvements have long-term value and utility and
are readily usable by a wide range of Life Science Industry tenants.  Generic
infrastructure improvements for each Property include:  reinforced concrete
floors, upgraded roof loading capacity and increased floor to ceiling heights;
heavy-duty HVAC systems and advanced environmental control technology;
significantly upgraded electrical, gas and plumbing infrastructure; and
laboratory benches.  

     The Company owns fee simple title in each of the Properties, except with
respect to 1311, 1401 and 1431 Harbor Bay Parkway, in which the Company owns a
commercial condominium interest, together with an undivided interest in the
common areas of the project in which the Property is a part.

     Leases in the Company's multi-tenant buildings typically have terms of 
three to seven years, while the single-tenant building leases typically have 
terms of 10 to 20 years.  As of December 31, 1997, approximately 76% of the 
Company's leases (on a square footage basis) were triple net leases, 
requiring tenants to pay substantially all real estate taxes and insurance, 
common area and other operating expenses (including increases thereto) in 
addition to base rent.   In addition, approximately 19% of the Company's 
leases (on a square footage basis) required the tenants to pay a majority of 
operating expenses. The remaining leases were gross leases, pursuant to which 
tenants generally pay for substantially all real estate taxes and insurance, 
common area and other operating expenses above those for an established base 
year.  Approximately 64% of the Company's leases (on a square footage basis) 
contained effective annual rent escalations that are either fixed (ranging 
from 2.5% to 4.0%) or indexed based on a consumer price index or other index. 
In addition, approximately 77% of the Company's leases (on a square footage 
basis) provided for the recapture of certain capital expenditures (such as 
HVAC systems maintenance and/or replacement, roof replacement and parking 
lot resurfacing), which the Company believes would typically be borne by the 
landlord in traditional office leases. The leases also typically give the 
Company the right to review and approve tenant alterations to the property.  
Generally, tenant-installed improvements remain the property of the Company 
after termination of the lease.  However, the Company is permitted under the 
terms of most of its leases to require that the tenant remove such 
improvements and restore the premises to their original condition.  As of 
December 31, 1997, the Company had 42 leases with a total of 35 tenants, and 
12 of the Properties were single-tenant properties. 

                                        5
<PAGE>

     As of December 31, 1997, the Company managed 21 of the Properties, and the
remaining Property was managed by a major tenant at such Property.  All material
decisions with respect to all of the Properties are made by the Company.  

     The following table sets forth certain information with respect to the
Properties as of December 31, 1997:

(1)  Annualized Base Rent means the annualized fixed base rental amount in
     effect as of December 31, 1997 (using rental revenue computed on a
     straight-line basis in accordance with GAAP) paid by tenants under the
     terms of their leases. 
(2)  Annualized Net Effective Rent is the Annualized Base Rent in effect as of
     December 31, 1997 (using rental revenue computed on a straight-line basis
     in accordance with GAAP), less (for gross leases) real estate taxes and 
     insurance, common area and other operating expenses and (for all leases) 
     amortized tenant improvements and leasing commissions.  
(3)  Of the 131,554 rentable square feet leased to Fred Hutchinson Cancer
     Research Center, leases with respect to 61,465 square feet, 28,466 square
     feet and 41,623 square feet are subject to expiration in 1998, 1999 and
     2004, respectively.  Fred Hutchinson Cancer Research Center has the right
     to terminate the leases at any time after November 30, 1999, upon 12 months
     prior written notice.
(4)  Of the 105,000 rentable square feet at 1413 Research Boulevard, leases with
     respect to 30,000 square feet are subject to expiration in 1999 and leases
     with respect to 75,000 rentable square feet are subject to expiration in
     2001.  
(5)  In addition to the base rent shown, MedImmune, Inc. pays $322,000 per year
     in reimbursements for improvements installed by the prior owner of the
     property.  These payments, which are accounted for as tenant recovery
     revenue, continue through the term of the lease.  The terms of the lease
     with MedImmune allow it to terminate such lease at various dates during the
     lease upon six to 12 months notice and the payment of a termination penalty
     determined based on the date of the termination.  In the event of such
     early termination, the remaining amount due over the term of the lease for
     improvements as described above must be paid in full.  
(6)  Gillette Capital Corporation is a wholly owned subsidiary of The Gillette 
     Company, the guarantor of the lessee's obligations under the lease.
(7)  Shire Pharmaceuticals, PLC subleases its space at 1550 East Gude Drive from
     Quest Diagnostics, Inc.
(8)  Weighted Average based on percentage of aggregate leased square feet.

ITEM 3. LEGAL PROCEEDINGS. 

     To the Company's knowledge, no litigation is pending against the Company,
other than routine actions and administrative proceedings, substantially all of
which are expected to be covered by liability insurance or which, in the
aggregate, are not expected to have a material adverse effect on the financial
condition, results of operations or cash flows of the Company.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

(1)  Period commencing on date Common Stock began trading on the NYSE and ending
     on March 27, 1998.  Prior to the Offering and the 1,765.923 to 1 stock
     split in connection therewith, Alexandria paid the following dividends on
     its Common Stock during 1996 and 1997:  (1)  March 26, 1996, distribution
     of Warrants, pro rata, to purchase 117,362 shares of common stock of Corixa
     Corporation; (2) September 30, 1996, $183.30 per share; (3) February 3,
     1997, $1,549.82 per share; (4) March 31, 1997, $750.01 per share; and (5)
     June 5, 1997, $475.00 per share.
(2)  Alexandria paid a distribution of $0.1275 per share of Common Stock on
     July 18, 1997 for the period May 28, 1997 through June 30, 1997, which is
     approximately equivalent to a quarterly distribution of $0.40 per share for
     the full calendar quarter.
(3)  On February 26, 1998, the Board of Directors of Alexandria authorized 
     the payment of a distribution of $0.40 per share of Common Stock for the 
     quarter ending March 31, 1998 to be paid on April 17, 1998 to holders of 
     record as of the close of business on April 7, 1998.

     Future distributions by Alexandria will be determined by the Board of 
Directors and will be dependent upon a number of factors, including actual 
cash available for distribution, the Company's financial condition and 
capital requirements, the annual distribution requirements under the REIT 
provisions of the Code and such other factors as the Board of Directors deems 
relevant.  To maintain its qualification as a REIT, Alexandria must make 
annual distributions to stockholders of at least 95% of its taxable income, 
determined without regard to deductions for dividends paid and by excluding 
any net capital gains.  Under certain circumstances, Alexandria may be 
required to make distributions in excess of cash flow available for 
distribution to meet such distribution requirements.  In such case, the 
Company may borrow funds or may raise funds through the issuance of 
additional debt or equity capital.  There can be no assurance that any such 
distributions will be made by Alexandria.

(6)  Of this amount, $2,147,000 represents the write-off of costs associated

     (loss) (computed in accordance with GAAP), excluding gains (or losses) from
     debt restructuring, sales of property and unusual items, plus real estate
     related depreciation and amortization and after adjustments for
     unconsolidated partnerships and joint ventures. For a more detailed
     discussion of FFO, see "Item 7. Management's Discussion and Analysis of
     Financial Condition and Results of Operations-Funds from Operations."


ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS. 

     The following discussion should be read in conjunction with the
consolidated financial statements and notes thereto appearing elsewhere in this
Form 10-K.

OVERVIEW

     Since its formation in October 1994, the Company has devoted substantially
all of its resources to the acquisition and management of high quality,
strategically located Life Science Facilities leased principally to tenants in
the Life Science Industry in its target markets. 

     In June 1997, the Company completed an initial public offering (the 
"Offering") of its common stock, par value $.01 per share (the "Common 
Stock"). In connection with the Offering (and related exercise of the 
underwriters' over-allotment option), 7,762,500 shares of Common Stock were 
issued.  Aggregate proceeds from the Offering (including proceeds from the 
exercise of the over-allotment option), net of underwriting discounts and 
commissions, advisory fees and offering costs, were approximately $138.9 
million.

     The Company receives income from rental revenue (including tenant 
recoveries) from its properties.  Of the 22 properties owned by the Company 
as of December 31, 1997 (the "Properties"), four were acquired in calendar 
year 1994, eight in 1996 (the "1996 Acquired Properties"), three in 1997 in 
connection with the Offering and seven in 1997 subsequent to the Offering 
(together, the "1997 Acquired Properties").  As a result of the Company's 
acquisition activities, the financial data shows significant increases in 
total revenues and expenses for 1997 compared to 1996, largely attributable 
to the 1997 Acquired Properties, and the recognition of a full year of 
revenues for the 1996 Acquired Properties.  For the foregoing reasons, and 
due to the effects of the Offering and related transactions, the Company does 
not believe its year-to-year historical financial data are comparable.  
Accordingly, the Company also has included pro forma financial information, 
which gives effect to the Offering and the acquisitions made in 1996 and 1997 
in connection therewith.

RESULTS OF OPERATIONS

COMPARISON OF THE YEAR ENDED DECEMBER 31, 1997 TO THE YEAR ENDED DECEMBER 31, 
1996

     Rental revenue increased by $12.7 million, or 98%, to $25.6 million for 
1997 compared to $12.9 million for 1996.  The increase resulted primarily 
from the 1996 Acquired Properties being owned for a full period and the 
addition of the 1997 Acquired Properties, which together contributed an 
additional $12.5 million of rental revenue in 1997.  Rental revenue from the 
Properties owned since January 1, 1996 (the "Same Properties") increased by 
$180,000, or 2%. This increase resulted primarily from the conversion of 
19,310 square feet of storage space to higher rent laboratory space at 10933 
North Torrey Pines Road in October 1996.

     Tenant recoveries increased by $4.2 million, or 100%, to $8.4 million 
for 1997 compared to $4.2 million for 1996.  The increase resulted primarily 
from the 1996 Acquired Properties being owned for a full period and the 
addition of the 1997 Acquired Properties, which together contributed an 
additional $3.8 million of tenant recoveries.  Tenant recoveries for the Same 
Properties increased by $416,000, or 19%, due to an increase in operating 
expenses (particularly utilities) being passed through to the tenants.  

     Other income increased by $273,000, or 48%, to $836,000 for 1997 
compared to $563,000 for 1996, resulting from an increase in interest income 
due to the investment of excess funds from the Offering and increased amounts 
in capital improvement reserve accounts.

     Rental operating expenses increased by $4.4 million, or 100%, to $8.8 
million for 1997 compared to $4.4 million for 1996.  The increase resulted 
almost entirely from the 1996 Acquired Properties being owned for a full 
period and the addition of the 1997 Acquired Properties, which together 
contributed an additional $4.0 million in operating expenses.  Operating 
expenses for the Same Properties increased by $401,000, or 17%, primarily due 
to increased utility expenses (due to greater usage) which were passed 
through to the tenants.

     General and administrative expenses increased by $504,000, or 26%, to 
$2.5 million for 1997 compared to $2.0 million for 1996 due to the Company's 
larger scope of operations and increased costs incurred as a result of being 
a public company.

     Special bonus of $353,000 in 1997 reflects a bonus paid to an officer of 
the Company in connection with the Offering.  Post retirement benefit expense 
of $632,000 and $438,000 in 1997 and 1996, respectively, reflects an 
adjustment for the non-cash accrual associated with a one-time post 
retirement benefit for an officer of the Company.  Stock compensation expense 
of $4.2 million was recorded in 1997 for the non-recurring, non-cash expense 
related to the issuance of stock grants and options to officers, directors 
and certain employees of the Company principally in connection with the 
Offering.

     Interest expense increased by $716,000, or 11%, to $7.0 million for 1997 
compared to $6.3 million for 1996.  The increase resulted from indebtedness 
incurred to acquire the 1996 Acquired Properties, offset by a reduction in 
ongoing interest expense due to the payoff of $72.7 million in secured notes 
payable in June 1997 with proceeds from the Offering.

     Acquisition LLC financing costs of $7.0 million in 1997 represent the 
portion of the purchase price of the membership interests in ARE 
Acquisitions, LLC (the "Acquisition LLC")  in excess of the cost incurred by 
the Acquisition LLC to acquire its three Life Science Facilities.

     Write-off of unamortized loan costs in 1997 represents the write-off of 
$2.1 million in loan costs associated with $72.7 million of secured notes 
repaid with proceeds of the Offering and $148,000 in loan costs associated 
with the payoff of debt in November 1997.


                                       14
<PAGE>

     Depreciation and amortization increased by $2.5 million, or 102%, to 
$4.9 million for 1997 compared to $2.4 million for 1996.  The increase 
resulted primarily from depreciation associated with the 1996 Acquired 
Properties being owned for a full period and the addition of the 1997 
Acquired Properties.

     As a result of the foregoing, the net loss was $2.8 million for 1997 
compared to net income of $2.2 million for 1996.

COMPARISON OF YEAR ENDED DECEMBER 31, 1996 TO YEAR ENDED DECEMBER 31, 1995

     Rental revenue increased by $4.9 million, or 61%, to $12.9 million for 
the year ended December 31, 1996 compared to $8.0 million for the year ended 
December 31, 1995.  The increase resulted primarily from the 1996 Acquired 
Properties, which contributed an additional $4.6 million of rental revenue in 
1996.  Rental revenue from the Properties owned since January 1, 1995 (the 
"1995 Same Properties") increased by $370,000, or 5%.  Of this increase, 
$320,000 resulted from a full year of rental income in 1996 resulting from 
the increase in occupancy at 11099 North Torrey Pines Road during 1995.

     Tenant recoveries increased by $2.5 million, or 147%, to $4.2 million 
for 1996 compared to $1.7 million for 1995.  The increase resulted primarily 
from the addition of the 1996 Acquired Properties, which contributed an 
additional $2.1 million of tenant recoveries.  Tenant recoveries from the 
1995 Same Properties increased by $395,000, or 23%.  Of this increase, 
$300,000 resulted from a new lease at 11099 North Torrey Pines Road.  The 
remaining increase resulted primarily from a new energy management system at 
10933 North Torrey Pines Road that allows the Company to more accurately 
measure and recover from its tenants certain costs of utility usage.

     Other income increased by $359,000, or 176%, to $563,000 for 1996 
compared to $204,000 for 1995.  The increase resulted primarily from the 
addition of the 1996 Acquired Properties, which contributed an additional 
$337,000 of other income.

     Rental operating expenses increased by $2.2 million, or 100%, to $4.4 
million for 1996 compared to $2.2 million for 1995.  The increase resulted 
primarily from the addition of the 1996 Acquired Properties, which 
contributed an additional $2.0 million of rental operating expenses.  Rental 
operating expenses from the 1995 Same Properties increased by $162,000, or 
7%, primarily as a result of an increase in expenses at 10933 North Torrey 
Pines Road.

     General and administrative expenses increased by $364,000, or 23%, to 
$2.0 million for 1996 compared to $1.6 million for 1995.  The increase 
resulted primarily from additional professional fees incurred during 1996.

     Post-retirement benefit expense in 1996 represents the non-cash accrual 
associated with a one-time post-retirement benefit for an officer of the 
Company.

     Interest expense increased by $2.8 million, or 80%, to $6.3 million for 
1996 compared to $3.5 million for 1995.  The increase resulted primarily from 
indebtedness incurred to acquire the 1996 Acquired Properties, which 
contributed an additional $2.3 million of interest expense, and debt 
outstanding under the Company's then-existing unsecured line of credit, which 
was repaid in July 1996.

     Depreciation and amortization increased by $737,000, or 44%, to $2.4 
million for 1996 compared to $1.7 million for 1995.  The increase resulted 
primarily from depreciation associated with the 1996 Acquired Properties.

     As a result of the foregoing, net income increased by $1.4 million, or 
184%, to $2.2 million for 1996 compared to $761,000 for 1995.

LIQUIDITY AND CAPITAL RESOURCES

THE OFFERING AND SECURED DEBT

     The Company completed the Offering in June 1997.  Aggregate proceeds of 
the Offering (including proceeds from the exercise of the over-allotment 
option), net of underwriting discounts and commissions, advisory fees, and 
offering costs, were approximately $138.9 million. The Company used such net 
proceeds, as well as $15.4 million in proceeds from two new mortgage loans, 
to repay outstanding debt of approximately $77.7 million.  In addition, in 
November 1997, the Company paid off $6.7 million of secured debt with funds 
from its unsecured line of credit obtained in connection with the Offering.  
Total secured debt as of December 31, 1997 included the following:

</TABLE>

UNSECURED LINE OF CREDIT

     In connection with the Offering, the Company obtained an unsecured line 
of credit providing for borrowings of up to $150 million, consisting of a 
$100 million activated portion and a $50 million portion that may be 
activated as needed at the Company's discretion (upon payment of an 
activation fee) provided that no default exists thereunder.  The line of 
credit provides for borrowings bearing interest at a floating rate based on 
the Company's election of either a LIBOR based rate or the higher of the 
bank's reference rate and the Federal Funds rate plus 0.5%.  For each LIBOR 
based advance, the Company must elect to fix the rate for a one, two, three 
or six month period.

     The line of credit contains financial covenants, including, among other 
things, maintenance of minimum market net worth, a total liabilities to gross 
asset value ratio, and a fixed charge coverage ratio (all as defined).  The 
Company was in compliance with all such covenants as of December 31, 1997.  
In addition, the terms of the line of credit restrict, among other things, 
certain investments, indebtedness, distributions and mergers.  Borrowings 
under the line of credit are limited to an amount based on a pool of 
unencumbered assets. Accordingly, as the Company acquires additional 
unencumbered properties, borrowings available under the line of credit will 
increase.  As of December 31, 1997, borrowings under the line of credit were 
limited to approximately $103 million, and $23 million was outstanding 
(leaving $80 million available), at a weighted average rate of interest of 
6.9%.

     The line of credit expires on May 31, 2000 and provides for annual 
extensions (provided there is no default) for two additional one-year periods 
upon notice by the Company and consent of the participating banks.  In 
addition, at the Company's election, the line of credit may be converted at 
any time to a term loan with principal installments over two years from the 
date of such conversion.

RESTRICTED CASH

     As of December 31, 1997, approximately $3.4 million had been set aside 
in a restricted cash account to complete the upgrade of laboratory space (as 
well as certain related improvements to the property) at 1102/1124 Columbia 
Street pursuant to an agreement between the Company and a tenant.  The 
Company also holds approximately $758,000 in security deposit reserve 
accounts based on the terms of certain lease agreements.

<PAGE>

LIQUIDITY REQUIREMENTS

     Although cash from operations required to fund interest expense has 
decreased substantially as a result of the Company's reduction in overall 
debt following the Offering, such reduction has been offset by an increased 
requirement to use cash from operations to meet distribution requirements to 
maintain the Company's REIT status.  The Company expects to make 
distributions from cash available for distribution, which is expected to 
exceed cash historically available for distribution as a result of the 
reduction in debt described above, as well as the addition of the 1996 and 
1997 Acquired Properties.  Cash that accumulates on a short-term basis will 
be used to reduce outstanding balances under the Company's unsecured line of 
credit or will be invested by the Company primarily in interest-bearing 
accounts and other short-term, interest-bearing securities that are 
consistent with the Company's qualification for taxation as a REIT.  The 
Company also believes that net cash provided by operations will be sufficient 
to fund its recurring non-revenue enhancing capital expenditures, tenant 
improvements and leasing commissions.

     The Company expects to meet certain long-term liquidity requirements, 
such as property acquisitions, scheduled debt maturities, renovations, 
expansions and other non-recurring capital improvements, through long-term 
secured and unsecured indebtedness, including borrowings under the line of 
credit, and the issuance of additional debt and/or equity securities.

EXPOSURE TO ENVIRONMENTAL LIABILITIES

     In connection with the acquisition of all of the Properties, the Company 
has obtained Phase I environmental assessments to ascertain the existence of 
any environmental liabilities or other issues.  The Phase I environmental 
assessments of the Properties have not revealed any environmental liabilities 
that the Company believes would have a material adverse effect on the 
Company's financial condition or results of operations taken as a whole, nor 
is the Company aware of any such material environmental liabilities.

HISTORICAL CASH FLOWS

     Net cash provided by operating activities for 1997 increased by $5.5 
million to $3.9 million compared to net cash used by operating activities of 
$(1.6) million for 1996.  The increase resulted primarily from operating cash 
flows from the addition of the 1996 Acquired Properties and the 1997 Acquired 
Properties.

     Net cash used in investing activities decreased by $7.3 million to 
$(87.6) million for 1997 compared to net cash used in investing activities of 
$(94.9) million for 1996.  This use of cash related primarily to  costs 
associated with the acquisition of the 1997 Acquired Properties.

     Net cash provided by financing activities decreased by $13.2 million to 
$84.1 million for 1997 compared to $97.3 million for 1996.  The decrease was 
impacted by $85.8 million of principal reductions in debt, retired 
principally with proceeds from the Offering, offset by $138.9 million in net 
proceeds from the Offering, $15.4 million in proceeds from secured debt, and 
$25.5 million in proceeds from unsecured lines of credit.  In addition, the 
Company paid dividends on the Common Stock of $8.8 million and dividends on 
preferred stock of $1.1 million during 1997.

CAPITAL EXPENDITURES, TENANT IMPROVEMENTS AND LEASING COSTS

     The following table sets forth total and weighted average per square 
foot capital expenditures (excluding those expenditures which are recoverable 
from tenants or are revenue-enhancing) and tenant improvements and leasing 
costs for the period from October 1994 (inception of operations) to December 
31, 1994, and for the years ended December 31, 1995, 1996, and 1997, 
attributable to leases that commenced at the Properties after acquisition by 
the Company.

</TABLE>


     Capital expenditures may fluctuate in any given period subject to the 
nature, extent, and timing of improvements required and to the extent they 
are recoverable from tenants.  The Company maintains an active preventive 
maintenance program in order to minimize required capital improvements.  

     Tenant improvements and leasing costs also may fluctuate in any given 
year depending upon factors such as the timing and extent of vacancies, the 
type of lease (renewal or replacement tenant), the involvement of external 
leasing agents and overall competitive market conditions.

INFLATION

     As of December 31, 1997, approximately 76% of the Company's leases (on a 
square footage basis) were triple net leases, requiring tenants to pay 
substantially all real estate taxes and insurance, common area and other 
operating expenses (including increases thereto).  In addition, approximately 
19% of the Company's leases (on a square footage basis) required the tenants 
to pay a majority of operating expenses.  In addition, approximately 64% of 
the Company's leases (on a square footage basis) contain effective annual 
rent escalations that are either fixed (ranging from 2.5% to 4.0%) or indexed 
based on the consumer price index or other index.  Accordingly, the Company 
does not believe that its earnings or cash flow are subject to any 
significant risk of inflation.  An increase in inflation, however, could 
result in an increase in the Company's variable rate borrowing cost, 
including borrowings under the unsecured line of credit.

IMPACT OF THE YEAR 2000

     The Company has evaluated the significance of the change from the year 
1999 to the year 2000 on its existing computer system and has taken steps to 
ensure that its computer system will not be adversely affected thereby. The 
financial impact of steps taken to accommodate the change for the year 2000 
is not anticipated to be material.  The Company relies in part on the 
computer systems of its vendors and other companies.  If any such company 
failed to become year 2000 compliant, the Company could be adversely affected 
thereby. The Company has surveyed several of its larger vendors, and all have 
responded that they either are currently year 2000 compliant, or are actively 
taking steps to become year 2000 compliant.

PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

     Due to the impact of the Offering and related transactions and the 
acquisitions by the Company in 1996 and 1997, the historical results of 
operations are not indicative of the Company's future results of operations. 
The following pro forma condensed consolidated financial information presents 
the results of operations of the Company as if the Offering (including the 
exercise of the over-allotment option) and related transactions occurred on 
January 1, 1996.  Pro forma results for the year ended December 31, 1997 do 
not include the operations of two of the Properties (14225 Newbrook Drive and 
1330 Piccard Drive) for the period prior to their acquisition by the 
Acquisition LLC (on January 13, 1997 and January 15, 1997, respectively).  
These Properties were owner-occupied prior to purchase and, as a result, 
there were no historical operating results for these Properties as rental 
properties.  The adjusted pro forma financial information presented below 
assumes that the new leases entered into with the sellers of such Properties 
were in effect for the entire period presented.  The pro forma and adjusted 
pro forma financial information presented below is based upon historical 
information and various assumptions and does not purport to present the 
actual results that would have occurred had the Offering and related 
transactions occurred on January 1, 1996, nor to project the Company's 
results of operations for any future period.

FUNDS FROM OPERATIONS

     Management believes that funds from operations ("FFO") is helpful to 
investors as a measure of the performance of an equity REIT because, along 
with cash flows from operating activities, financing activities and investing 
activities, it provides investors with an understanding of the ability of the 
Company to incur and service debt, to make capital expenditures and to make 
distributions.  The Company computes FFO in accordance with standards 
established by the Board of Governors of the National Association of Real 
Estate Investment Trusts ("NAREIT") in its March 1995 White Paper (the "White 
Paper"), which may differ from the methodology for calculating FFO utilized 
by other equity REITs, and, accordingly, may not be comparable to such other 
REITs. Further, FFO does not represent 

                                        19
<PAGE>

amounts available for management's discretionary use because of needed 
capital replacement or expansion, debt service obligations, or other 
commitments and uncertainties.  The White Paper defines FFO as net income 
(loss) (computed in accordance with generally accepted accounting principals 
("GAAP")), excluding gains (or losses) from debt restructuring, sales of 
property and unusual items, plus real estate related depreciation and 
amortization and after adjustments for unconsolidated partnerships and joint 
ventures.  FFO should not be considered as an alternative to net income 
(determined in accordance with GAAP) as an indication of the Company's 
financial performance or to cash flows from operating activities (determined 
in accordance with GAAP) as a measure of the Company's liquidity, nor is it 
indicative of funds available to fund the Company's cash needs, including its 
ability to make distributions.  (See "-Historical Cash Flows" for information 
regarding these measures of cash flow).

     The following tables present the Company's FFO for the year ended 1997 
on a historical, pro forma and adjusted pro forma basis and for the years 
ended 1996 and 1995 on a historical basis.  The adjusted pro forma 
information for the year ended December 31, 1997 assumes that leases entered 
into with sellers of previously owner-occupied properties were in effect for 
the entire period presented:

                        Report of Independent Auditors

To the Board of Directors and Stockholders of
Alexandria Real Estate Equities, Inc.

We have audited the accompanying consolidated balance sheets of Alexandria 
Real Estate Equities, Inc. and subsidiaries (the "Company") as of December 
31, 1997, and 1996, and the related consolidated statements of operations, 
stockholders' equity, and cash flows for the years ended December 31, 1997, 
1996 and 1995. Our audits also included the consolidated financial statement 
Schedule III, rental properties and accumulated depreciation. These 
consolidated financial statements and consolidated financial statement 
schedule are the responsibility of the Company's management. Our 
responsibility is to express an opinion on these consolidated financial 
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the consolidated financial position 
of the Company as of December 31, 1997 and 1996, and the consolidated results 
of its operations and its cash flows for the years ended December 31, 1997, 
1996 and 1995, in conformity with generally accepted accounting principles. 
Also, in our opinion, the related consolidated financial statement schedule 
referred to above, when considered in relation to the consolidated financial 
statements taken as a whole, presents fairly in all material respects the 
information set forth therein.

                  Notes to Consolidated Financial Statements

   POLICIES

BACKGROUND

Alexandria Real Estate Equities, Inc. (known as Health Science Properties, 
Inc. prior to 1997), a Maryland corporation (the "Company"), is a real estate 
investment trust ("REIT") formed in 1994.

The Company and its subsidiaries were formed to acquire, manage and 
selectively develop properties for lease principally to participants in the 
life science industry ("Life Science Facilities"). As of December 31, 1997 
and 1996, the Company owned 22 and 12 Life Science Facilities, respectively, 
in four and three states, respectively, consisting of 1,748,000 and 1,031,000 
rentable square feet, respectively.

BASIS OF PRESENTATION

The consolidated financial statements include the accounts of the Company and 
its wholly owned subsidiaries which own, directly or indirectly, Life 
Science Facilities. All significant intercompany accounts and transactions 
have been eliminated in consolidation.

THE INITIAL PUBLIC OFFERING AND RELATED TRANSACTIONS

On June 2, 1997, the Company completed an initial public offering (the 
"Offering") of 6,750,000 shares of common stock. The Offering price was 
$20.00 per share, resulting in gross proceeds of $135,000,000. On June 26, 
1997, the underwriters exercised their over-allotment option provided for in 
the Offering, and the Company issued an additional 1,012,500 shares of common 
stock, resulting in additional gross proceeds of $20,250,000. The aggregate 
net proceeds of the Offering (including exercise of the over-allotment 
option), net of underwriting discounts and commissions, advisory fees and 
offering costs, were approximately $138,890,000.

THE INITIAL PUBLIC OFFERING AND RELATED TRANSACTIONS (CONTINUED)

The following transactions also occurred in June 1997 in connection with the 
Offering:

- -    The Company paid off debt of approximately $77,723,000, including (i)
     mortgage debt of $72,698,000, (ii) debt of $2,500,000 outstanding under
     its prior unsecured line of credit, and (iii) debt of $2,525,000 to Health
     Science Properties Holding Corporation ("Holdings"). Holdings owned all of
     the Company's common stock prior to the Offering and 15.5% of the common
     stock of the Company after the Offering and the exercise of the over-
     allotment option.
  
- -    The Company obtained two new mortgage loans totaling $15,360,000.
  
- -    The Company acquired an entity that owns three Life Science Facilities
     from affiliates of PaineWebber Incorporated, the lead managing underwriter
     for the Offering, for an aggregate purchase price of $58,844,000 (see
     Note 9).
  
- -    Each previously outstanding share of the Company's common stock was split
     into 1,765.923 shares of common stock. The share data as of and for the
     years ended December 31, 1996 and 1995 has been restated to reflect the
     effects of the stock split.
  
- -    All of the previously outstanding shares of Series T preferred stock were
     redeemed at their stated value ($1,200 in the aggregate) (see Note 6).
  
- -    All of the previously outstanding shares of Series U preferred stock and
     Series V preferred stock were converted into shares of common stock (7,354
     shares in the aggregate for Series U and 1,659,239 shares in the aggregate
     for Series V) (see Note 6).
  
- -    Officers, directors and certain employees of the Company were granted an
     aggregate of 152,615 shares of the Company's common stock. In addition,
     officers, directors and certain employees of the Company were granted
     options to purchase 57,000 shares of the Company's common stock in
     substitution for stock options previously issued by Holdings (see Notes 5
     and 8). These options were exercised at a nominal exercise price in
     connection with the Offering.

THE INITIAL PUBLIC OFFERING AND RELATED TRANSACTIONS (CONTINUED)

- -    Officers, directors and employees of the Company were granted options
     under the Company's 1997 stock option plan to purchase an aggregate of
     600,000 shares of common stock of the Company at the Offering price (see
     Note 8).
  
- -    A special bonus of $353,000 was paid to an officer of the Company.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amounts of assets and liabilities, the disclosure of 
contingent assets and liabilities at the date of the financial statements and 
the reported amounts of revenues and expenses during the reporting period. 
Actual results could differ from those estimates.

CASH EQUIVALENTS

The Company considers all highly liquid investments with original maturities 
of three months or less when purchased to be cash equivalents.

RENTAL PROPERTIES

Rental properties consist of the Company's portfolio of Life Science 
Facilities, recorded at cost. Costs associated with acquiring and renovating 
properties are capitalized as incurred. If events or circumstances indicate 
that the carrying amount of a property may be impaired, the Company would 
make an assessment of its recoverability by estimating the future 
undiscounted cash flows, excluding interest charges, of the property. If the 
carrying amount were to exceed the aggregate future cash flows, the Company 
would recognize an impairment loss to the extent the carrying amount exceeds 
the fair value of the property. Based upon such periodic assessments, no 
impairment has been determined and no rental properties carrying amounts have 
been adjusted.

   POLICIES (CONTINUED)

RENTAL PROPERTIES (CONTINUED)

Maintenance and repairs are expensed as incurred. Major replacements and 
betterments are capitalized and depreciated over their estimated useful lives.

Depreciation is provided using the straight-line method using estimated lives 
of 30 to 40 years for buildings and building improvements, 20 years for land 
improvements, and the term of the respective lease for tenant improvements.

RESTRICTED CASH

Restricted cash as of December 31, 1997 and 1996, consists of a tenant 
improvement reserve of $3,364,000 and $4,715,000, respectively, established 
by the Company pursuant to a lease at one of the Company's properties, funds 
held in trust of $1,966,000 and none, respectively, as additional security on 
a note with the City of Seattle, and security deposit funds and other 
restricted cash of $1,469,000 and $870,000, respectively. In connection with 
the repayment of the note with the City of Seattle, the cash held in trust was 
returned to the Company in February 1998 (see Note 4).

LOAN FEES AND COSTS

Fees and costs incurred in obtaining long-term financing are amortized over 
the terms of the related loans and included in interest expense.

RENTAL INCOME

Rental income from leases with scheduled rent increases, free rent and other 
rent adjustments are recognized on a straight-line basis over the lease term. 
Amounts currently recognized as income, and expected to be received in later 
years, are included in tenant receivables and deferred rent. Amounts received 
currently, but recognized as income in future years, are included in unearned 
rent.

OTHER INCOME

Other income consists of interest income and other income associated with the
operations of the properties. Interest income was $588,000, $118,000 and
$57,000 in 1997, 1996 and 1995, respectively.

LEASING COMMISSIONS

Leasing commissions are amortized on a straight-line basis over the term of 
the related lease.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The following disclosures of estimated fair value of financial instruments at 
December 31, 1997 and 1996 were determined by management using available 
market information and appropriate valuation methodologies. Considerable 
judgment is necessary to interpret market data and develop estimated fair 
value. The use of different market assumptions and/or estimation 
methodologies may have a material effect on the estimated fair value amounts.

Based on the borrowing rates currently available to the Company for bank 
loans with similar maturities, the fair value of secured notes payable as of 
December 31, 1997 and 1996 is approximately $46,822,000 and $113,215,000, 
respectively.  All other financial instruments are stated at amounts that 
approximate their fair value.

NET (LOSS) INCOME PER SHARE

Historical per share data has not been presented because it is not meaningful 
due to the material changes in the Company's capital structure as a result of 
the Offering.

The Company has adopted Statement of Financial Accounting Standards No. 128 
("FAS 128") and has restated pro forma net income per share for the years 
ended December 31, 1996 and 1995. Because the impact of the Company's stock 
options outstanding as of December 31, 1997 is antidilutive, diluted net 
income per share is not presented for 1997. There were no dilutive stock 
options on a pro forma basis for 1996 and 1995.

NET (LOSS) INCOME PER SHARE (CONTINUED)

Pro forma shares of common stock outstanding for the years ended December 31, 
1997 and 1996 include all shares outstanding after giving effect to the 
1,765.923 to 1 stock split, the issuance of stock grants, the issuance and 
exercise of substitute stock options and the conversion of the Series U and 
Series V preferred stock. In addition, shares issued to the public in 
connection with the Offering have been weighted for the period of time they 
were outstanding. Pro forma shares of common stock outstanding for the year 
ended December 31, 1995 include all shares outstanding after giving effect to 
the 1,765.923 to 1 stock split.

   POLICIES (CONTINUED)

INCOME TAXES

As a REIT, the Company is not subject to federal income taxation as long as 
it meets a number of organizational and operational requirements and 
distributes all of its taxable income to its stockholders. Since the Company 
believes it has met these requirements and the Company's distributions 
exceeded taxable income, no federal income tax provision has been reflected 
in the accompanying consolidated financial statements for 1997 and 1996. If 
the Company fails to qualify as a REIT in any taxable year, the Company will 
be subject to federal income tax on its taxable income at regular corporate 
tax rates. For the year ended December 31, 1997, the Company reported that 
37.6% of its distributions with respect to common stock represented a return 
of capital for federal income tax purposes, while none of the distributions 
for the year ended December 31, 1996 represented a return of capital.

For the year ended December 31, 1995, before the Company elected to be taxed 
as a REIT, deferred income taxes were recognized for tax consequences of 
temporary differences resulting from income and expense items reported for 
financial accounting and tax purposes in different periods and tax net 
operating loss carryforwards.

RECLASSIFICATIONS

Certain prior year amounts have been reclassified to conform to the current 
year presentation.

2. RENTAL PROPERTIES (CONTINUED)

Four of the Company's rental properties are encumbered by deeds of trust and 
assignments of rents and leases associated with the properties (see Note 4). 
The net book value of these properties as of December 31, 1997 is $70,663,000.

The Company leases space under noncancelable leases with remaining terms of 1 
to 20 years. Certain tenants are also obligated to reimburse the Company for 
specific operating expenses.

The Company capitalizes interest to properties under construction and 
renovation during the period the asset is undergoing activities to prepare it 
for its intended use. Total interest capitalized was $96,000 in 1997. Total 
interest incurred for the years ended December 31, 1997, 1996 and 1995 was 
$7,139,000, $6,327,000 and $3,553,000, respectively.

A majority of the Company's lease agreements require that the lessee pay all 
taxes, maintenance, insurance and certain other operating expenses applicable 
to the leased properties.

Minimum lease payments to be received under the terms of the operating lease 
agreements, excluding expense reimbursements, as of December 31, 1997, are as 
follows (in thousands):

3. UNSECURED LINE OF CREDIT

In connection with the Offering, the Company obtained an unsecured line of
credit providing for borrowings of up to $150,000,000, consisting of a
$100,000,000 activated portion and a $50,000,000 portion that may be activated
as needed at the Company's discretion (upon the payment of an activation fee)
provided no default exists under the line of credit facility. Borrowings under
the line of credit bear interest at a floating rate which is based on the

advance, the Company must elect to fix the rate for a one, two, three or six 
month period.

The line of credit contains financial covenants, including, among other 
things, maintenance of minimum market net worth, a total liabilities to gross 
asset value ratio, and a fixed charge coverage ratio (all as defined). The 
Company was in compliance with all covenants as of December 31, 1997. In 
addition, the terms of the line of credit restrict, among other things, 
certain investments, indebtedness, distributions and mergers. Borrowings 
under the line of credit are limited to an amount based on a pool of 
unencumbered assets. Accordingly, as the Company acquires additional 
unencumbered properties, borrowings available under the line credit will 
increase.  As of December 31, 1997, borrowings under the line of credit were 
limited to approximately $103,000,000, and $23,000,000 was outstanding 
(leaving $80,000,000 available), at a weighted average rate of interest of 
6.9%.

The line of credit expires on May 31, 2000 and provides for annual extensions 
(provided there is no default) for two additional one-year periods. In 
addition, at the Company's election, the line of credit may be converted at 
any time to a term loan with principal installments over two years from the 
date of such conversion.

In connection with obtaining the line of credit, the Company incurred 
$705,000 in fees and costs, which are being amortized over the term of the 
line of credit. In addition, the Company is required to continue to pay 
certain periodic fees for the line of credit, depending on the usage of the 
facility. The fees are included as part of interest expense.

4. SECURED NOTES PAYABLE

As of December 31, 1997, the Company had three notes payable to banks and an 
insurance company, secured by first and second deeds of trust on four rental 
properties. The notes bear interest at fixed rates ranging from 7.17% to 
9.00% and are due at various dates through 2016. As of December 31, 1997 and 
1996, the outstanding balances under these notes were $47,817,000 and 
$61,292,000, respectively.

As of December 31, 1996, the Company had an aggregate of $51,890,000 
outstanding under two notes payable and two secured lines of credit with 
PaineWebber Incorporated, the City of Seattle and two banks. The loans bore 
interest at variable rates based upon LIBOR or the prime rate. As of December 
31, 1996, the interest rates on these loans ranged from 8.28% to 9.75%. In 
connection with the Offering, the Company repaid $46,030,000 of the balance 
outstanding as of December 31, 1996. The remaining

$5,860,000 was repaid in November 1997. In connection with the retirement of 
these loans, the Company wrote-off $2,147,000 of unamortized loan costs, 
including the cost of certain interest rate cap agreements.

Future principal payments due on secured notes payable as of December 31, 
1997, are as follows (in thousands):

5. NON-CASH TRANSACTIONS

Stock compensation expense represents non-cash compensation expense 
associated with stock grants and stock options issued to officers, directors 
and certain employees of the Company in connection with the Offering. Stock 
compensation expense of $4,239,000 was recognized to record the stock grants 
and the issuance and exercise of substitute stock options (see Note 8).

In connection with the Offering, outstanding shares of the Company's Series U 
preferred stock and Series V preferred stock were converted into shares of 
common stock (see Note 6). The common stock issued was recorded at the book 
value of the Series U preferred stock and the Series V preferred stock (an 
aggregate of $27,061,000).

6. PREFERRED STOCK AND EXCESS STOCK

SERIES V CUMULATIVE CONVERTIBLE PREFERRED STOCK

Prior to the Offering, the Company had 27,500 shares of manditorily 
redeemable Series V cumulative convertible preferred stock outstanding. The 
stated value of each share was $1,000. In connection with the Offering, the 
shares were converted into 1,659,239 shares of common stock. The conversion 
rate was computed to provide for an internal rate of return on the stated 
value of each share, equal to 20% less the return previously received from 
prior dividends.

SERIES V CUMULATIVE CONVERTIBLE PREFERRED STOCK (CONTINUED)

Prior to conversion, Series V preferred stockholders were entitled to 
dividends at an annual rate of 10% of the stated value per share during the 
first twelve dividend periods or such larger amount as would be payable on an 
as converted basis if the Series V preferred stock were converted to common 
stock. Dividends were cumulative and payable in quarterly equal installments 
on March 31, June 30, September 30, and December 31 of each year. Offering 
costs associated with the issuance of the Series V preferred stock were 
deducted from the proceeds of the issuance. Until the conversion of the 
Series V preferred stock into shares of common stock in 1997, the Company 
accreted the amount of the offering costs and the difference between the 
minimum yield requirement on the Series V preferred stock (20% per annum) and 
the minimum dividend payment as a charge to additional paid-in capital.

SERIES T AND SERIES U PREFERRED STOCK

Holders of each of the Series T and Series U preferred stock were entitled to 
dividends at an annual rate of 8.5% of the stated value per share. In 
connection with the Offering, all of the previously outstanding shares of 
Series T preferred stock (12 shares) were redeemed at their stated value 
($1,200 in the aggregate). In connection with the Offering, all of the 
previously outstanding shares of Series U preferred stock (220 shares) were 
converted into an aggregate of 7,354 shares of common stock.

PREFERRED STOCK AND EXCESS STOCK AUTHORIZATIONS

The charter of the Company authorizes the issuance of up to 100,000,000 
shares of preferred stock and 200,000,000 shares of excess stock (as 
defined), none of which was issued and outstanding at December 31, 1997.

POST-RETIREMENT BENEFIT

In 1997, in connection with the Offering, an officer of the Company retired. 
In connection with the officer's retirement, the Company agreed to pay a 
post-retirement benefit equal to $150,000 for each of the first three years 
following the Offering, and $90,000 per year (plus an annual increase of 2% 
per year) thereafter for the remainder of the longer of the executive's life 
and the executive's current spouse's life. In 1997 and 1996, the Company 
recorded a post-retirement expense for past services equal to $632,000 and 
$438,000, respectively (pursuant to a prior agreement). The accrual was based 
upon the estimated number of payments to be made, discounted at a rate of 8%. 
As of December 31, 1997, the accrued liability for post-retirement benefit is 
$1,037,000. For the year ended December 31, 1997, the Company paid $75,000 
under the retirement agreement of which $42,000 represented interest.

EMPLOYEE RETIREMENT SAVINGS PLAN

Effective January 1, 1997, the Company adopted a retirement savings plan 
pursuant to Section 401(k) of the Internal Revenue Code ("Code"), whereby 
participants may contribute a portion of their compensation to their 
respective retirement accounts, in an amount not to exceed the maximum 
allowed under the Code. The plan provides for matching contributions by the 
Company, which amounted to $36,000 for the year ended December 31, 1997. Plan 
participants are immediately vested in their contributions and in the 
matching contributions by the Company.

CONCENTRATION OF CREDIT RISK

The Company maintains its cash and cash equivalents at insured financial 
institutions. The combined account balances at each institution periodically 
exceed FDIC insurance coverage, and, as a result, there is a concentration of 
credit risk related to amounts in excess of FDIC insurance coverage. 
Management believes that the risk is not significant.

The Company is dependent on rental payments from a limited number of tenants, 
and the inability of any single tenant to make its lease payments could 
adversely affect the Company and its ability to make distributions to 
stockholders. As of December 31, 1997, the Company had 42 leases with a total 
of 35 tenants, and 12 of the Company's 22 properties were single tenant 
properties. At December 31, 1997, three of the Company's tenants accounted 
for approximately 29.5% of the Company's aggregate annualized base rent.

CONCENTRATION OF CREDIT RISK (CONTINUED)

The Company does not generally require collateral or other security from its 
tenants other than security deposits. The Company has available from certain 
tenants two irrevocable letters of credit totaling $858,000 which are used as 
security deposits for two leases.

8. STOCK OPTION PLANS AND STOCK GRANTS

The Company has elected to follow Accounting Principles Board Opinion No. 25, 
"Accounting for Stock Issued to Employees" ("APB 25") and related 
Interpretations in accounting for its employee and director stock options, 
stock grants and stock appreciation rights. Under APB 25, if the exercise 
price of employee and director stock options granted by the Company equals 
the market price of the underlying stock on the date of grant, no 
compensation expense is recognized.

1997 STOCK OPTION PLAN

In connection with the Offering, the Company adopted a stock option and 
incentive plan (the "1997 Stock Option Plan"). The 1997 Stock Option Plan is 
administered by the Compensation Committee of the Board of Directors and 
provides for the grant of incentive stock options intended to qualify as such 
under Section 422 of the Code, non-qualified stock options, stock 
appreciation rights and restricted stock to employees, officers, directors 
and independent contractors (including non-employee directors) of the Company 
with respect to 900,000 shares of common stock. The 1997 Stock Option Plan 
permits the Compensation Committee to select eligible employees, officers, 
directors and independent contractors (including non-employee directors) of 
the Company to receive awards, to determine the type and number of awards to 
be granted and to determine the terms, conditions, restrictions and 
performance criteria relating to any award. As of December 31, 1997, there 
were 701,000 options outstanding under the 1997 Stock Option Plan. The 
Company has reserved 900,000 shares of common stock for issuance under the 
1997 Stock Option Plan.

During the year ended December 31, 1997, the Company granted 701,000 stock 
options under the 1997 stock option plan at exercise prices ranging from 
$20.00 to $30.94 (the market price at date of grant). All of these options 
have a ten year term. Options for 671,000 shares vest ratably in three annual 
installments from the date of grant. The

remaining 30,000 options (which were issued to non-employee directors) were 
exercisable immediately upon the date of grant.

Pro forma information regarding net income and earnings per share has been 
determined as if the Company had accounted for its employee stock options 
under the fair value method. The fair value of the options issued under the 
1997 Stock Option Plan was estimated at the date of grant using a 
Black-Scholes option pricing model with the following weighted-average 
assumptions for 1997: risk-free interest rate of 5.82%; dividend yield 
ranging from 5.17% to 8%; volatility factor of the expected market price of 
the Company's common stock of 28.7%; and a weighted average expected life of 
the option of five years.

For purposes of the following pro forma disclosures for the year ended 
December 31, 1997, the estimated fair value of these options has been 
amortized to expense over the vesting periods (in thousands, except per share 
information):

Exercise prices for options outstanding as of December 31, 1997 range from 
$20.00 to $30.94. The weighted average contractual life of those options is 
9.5 years.

PRIOR STOCK OPTION PLAN

Prior to the Offering, the Company had a ten-year incentive and nonqualified 
stock option plan (the "Prior Plan") for certain employees and non-employee 
directors of the Company.

Under the Prior Plan, holders of options to purchase common stock of Holdings 
granted under stock option plans of Holdings ("Holdings Stock Options") were 
eligible, under certain circumstances (including the Offering), to receive 
substitute stock options of the Company in substitution for previously 
granted Holdings Stock Options. As such, in connection with the Offering, 
officers, directors and certain employees of the Company received substitute 
stock options to purchase 57,000 shares of common stock of the Company under 
the Prior Plan. Such substitute stock options were exercised in connection 
with the Offering at a nominal exercise price. No further stock options were 
issued under the Prior Plan. In connection with the issuance of the 
substitute stock options, the Company recognized $1,187,000 of stock 
compensation expense.

The following table sets forth certain information regarding activity in
Holdings Stock Options, including (i) the grant date of the Holdings Stock
Options, (ii) the number of substitute stock options that were granted in
connection with the Offering in substitution for the underlying Holdings Stock
Options and (iii) the weighted average exercise price of substitute stock
options for shares of the Company's common stock.

9. PURCHASE OF ACQUISITION LLC

During January 1997, the Company assigned its rights to purchase three Life
Science Facilities to an entity owned by affiliates of PaineWebber
Incorporated ("PaineWebber"), the lead managing underwriter of the Offering
(the "Acquisition LLC"). In January 1997, the Acquisition LLC acquired the
three Life Science Facilities for $51,871,000 from unaffiliated sellers. In
connection with the Offering, the Company acquired 100% of the membership
interests in the Acquisition LLC from the PaineWebber affiliates.

The Company's purchase price for the membership interests ($58,844,000)
exceeded the cost incurred by the Acquisition LLC to acquire the properties
($51,871,000). The Company's acquisition of the membership interests in the
Acquisition LLC has been recorded as a financing transaction, with the excess
of the purchase price of such membership interests over the cost of the
Acquisition LLC to acquire the properties ($6,973,000) being reflected as a
financing cost in the accompanying consolidated statement of operations.

10. RELATED PARTY TRANSACTIONS

During 1997, 1996 and 1995, the Company incurred $3,358,000, $1,708,000 and
$369,000, respectively, for legal services provided by a firm of which a
minority shareholder of Holdings is a member.

During 1996, Holdings advanced to the Company $2,483,000 bearing interest at a
rate of 10% per annum which was due on demand. For the year ended December 31,
1996, $162,000 of interest was accrued and $42,000 was paid on this advance.
During 1997 in connection with the Offering, the Company repaid this advance
plus accrued interest.

and Chief Operating Officer; PROVIDED that effective as of January 1, 1998,
Officer shall be employed by and serve the Corporation as its Vice Chairman and
Chief Executive Officer.  In addition, Officer agrees to serve in such
additional capacity consistent with the Officer's current position as a senior
executive officer as may be determined by the Board of Directors of the
Corporation (the "Board").  Corporation agrees to employ and retain Officer in
such capacities.  Officer shall

Corporation as shall be necessary to perform the duties of such positions.  
Officer shall report to the Chairman and prior to January 1, 1998, the Chief 
Executive Officer and at all times during the Term (as defined in Paragraph 2 
below) of this Agreement shall have powers and duties at least commensurate 
with his position as senior executive officer.  Officer shall be based at the 
principal executive offices of Corporation in the Los Angeles, California 
metropolitan area, except for required travel on Corporation's business.

2.   TERM OF EMPLOYMENT.

          The Term (the "Term") of this Agreement shall be for a period 
commencing on January 1, 1997 and ending on December 31, 2000 (the 
"Termination Date"), unless terminated earlier pursuant to this Agreement 
(the "Early Termination Date").  Commencing on December 31, 2000 and each 
subsequent anniversary thereof, the Term shall be automatically extended for 
one (1) additional year unless, no later six (6) months before such date, 
either party shall have given written notice to the other that it does not 
wish to extend the Term of this Agreement.  References herein to the Term of 
this Agreement shall refer to both the initial Term and any such extended 
Term.

3.   COMPENSATION, BENEFITS AND REIMBURSEMENT.

          3.1  BASE SALARY.  During the Term of this Agreement Officer shall be 
entitled to the following base salary:

               (a)  MINIMUM BASE.  During the Term of this Agreement and 
subject to the terms and conditions set forth herein, Corporation agrees to 
pay to Officer an annual "Base Salary" of Two Hundred Thirty Five Thousand 
Dollars ($235,000), or such higher amount as may from time to time be 
determined by Corporation.  Unless otherwise agreed in writing by Officer and 
Corporation, the salary shall be payable in substantially equal semimonthly 
installments in accordance with the standard policies of Corporation in 
existence from time to time.

               (b)  EARNED BASE SALARY.  For purposes of any early 
termination of this Agreement as provided in Paragraph 4 below, the term 
"Earned Base Salary" shall mean all semimonthly installments of the Base 
Salary which have become due and payable to Officer, together with any 
partial monthly installment prorated on a daily basis up to and including the 
applicable Termination Date. 

                                      2

<PAGE>

          3.2  INCREASES IN BASE SALARY.  Officer's Base Salary shall be 
reviewed no less frequently than on each anniversary of the Effective Date 
during the Term by the Board (or such committee as may be appointed by the 
Board for such purpose). The Base Salary payable to Officer shall be 
increased on each such anniversary date (and such other times as the Board or 
a committee of the Board may deem appropriate during the Term of this 
Agreement) to an amount determined by the Board (or a committee of the 
Board).  Each such new Base Salary shall become the base for each successive 
year increase; PROVIDED, HOWEVER, that such increase, at a minimum, shall be 
equal to the cumulative cost-of-living increment as reported in the "Consumer 
Price Index, Los Angeles, California, All Items," published by the U.S. 
Department of Labor (using January 1, 1994 as the base date for comparison).  
Any increase in Base Salary or other compensation shall in no way limit or 
reduce any other obligations of Corporation hereunder and, once established 
at an increased specified rate, Officer's Base Salary shall not be reduced 
unless Officer otherwise agrees in writing.

          3.3  BONUS.  During the Term of this Agreement Officer is eligible 
for the following bonus:

               (a)  MINIMUM BONUS.  Officer shall be eligible to receive a 
bonus for each fiscal year of Corporation (or portion thereof) during the 
Term of this Agreement, with the actual amount of any such bonus to be 
determined in the sole discretion of the Board (or a committee of the Board) 
based upon its evaluation of Officer's performance during such year and such 
other factors and conditions as the Board (or a committee of the Board) deems 
relevant.  Any such bonus shall be payable within seventy-five (75) days 
after the end of Corporation's fiscal year to which such bonus relates.  The 
Board shall, at an appropriate subsequent time, consider the establishment of 
an annual incentive compensation plan providing for the payment of a minimum 
annual bonus based upon the achievement of certain objective criteria for the 
benefit of Officer and other specified executive officers of Corporation.

               (b)  DETERMINATION OF BONUS.  With respect to the period 
commencing upon consummation of an initial public offering (the "IPO") of the 
Corporation's common stock, par value $.01 per share (the "Common Stock"), 
and ending on December 31, 1997, and with respect to each calendar year 
thereafter during the Term, the bonus payable pursuant to Subparagraph (a), 
if any, shall be based upon such factors as the Board (or a committee 
thereof) deems appropriate, which may include the enhancement of stockholder 
value based upon Funds From Operations (as defined in the White Paper on 
Funds From Operations approved by the Board of Governors of the National 
Association of Real Estate Investment Trusts in March 1995) as determined in 
good faith by the 

                                      3

<PAGE>

Board during such period, divided by the weighted average 
number of shares of Common Stock outstanding during such period.   

          3.4  ADDITIONAL BENEFITS.  During the Term of this Agreement, 
Officer shall be entitled to the following additional benefits:

               (a)  OFFICER BENEFITS.  Officer shall be eligible to 
participate in such of Corporation's benefit and deferred compensation plans 
as are made available to executive officers of Corporation, including, 
without limitation, Corporation's stock incentive plans, annual incentive 
compensation plans, profit sharing/pension plans, deferred compensation 
plans, annual physical examinations, dental, vision, sick pay, and medical 
plans, personal catastrophe and accidental death insurance plans, financial 
planning and automobile arrangements, retirement plans and supplementary 
executive retirement plans, if any.  For purposes of establishing the length 
of service under any benefit plans or programs of Corporation, Officer's 
employment with the Corporation will be deemed to have commenced on the 
Original Effective Date of this Agreement. Until Corporation adopts a package 
of health and medical benefits, Corporation shall promptly reimburse Officer 
for payments made by Officer (i) with respect to the continuation of benefits 
provided by Officer's previous employer pursuant to Section 4980B ("COBRA") 
of the Internal Revenue Code of 1986, as amended (the "Code"), and (ii) upon 
expiration of COBRA coverage to maintain substantially similar health and 
medical benefits coverage for Officer and his family.

               (b)  VACATION.  Officer shall be entitled to a minimum of five 
(5) weeks of vacation during each year during the Term of this Agreement and 
any extensions thereof, prorated for partial years.  Any accrued vacation not 
taken during any year may be carried forward to subsequent years; PROVIDED, 
that Officer may not accrue more than eight (8) weeks of unused vacation at 
any time.

               (c)  LIFE INSURANCE.  During Term of this Agreement, 
Corporation shall, at its sole cost and expense, procure and keep in effect 
term life insurance (a minimum three (3) year term certain policy) on the 
life of Officer, payable to such beneficiaries as Officer may from time to 
time designate, in the aggregate amount of One Million Dollars ($1,000,000).  
Such policy shall be owned by Officer or by a member of his immediate family. 
Corporation shall have no incidents of ownership therein.

               (d)  DISABILITY INSURANCE.  During the Term of this Agreement, 
Corporation shall, at its sole cost and expense, procure and keep in effect 
disability insurance similar to Officer's current disability insurance policy 
on Officer, payable to

                                      4

<PAGE>

Officer in an annual amount not less than sixty percent (60%) of Officer's 
then existing Base Salary (the "Disability Policy").  For purposes of this 
Agreement, "Permanent Disability" shall have the same meaning as is ascribed 
to such term in the Disability Policy (including the COBRA Disability Policy) 
covering Officer at the time of occurrence of such Permanent Disability.

               (e) REIMBURSEMENT FOR EXPENSES.  During the Term of this 
Agreement, Corporation shall reimburse Officer for all reasonable 
out-of-pocket business and/or entertainment expenses incurred by Officer for 
the purpose of and in connection with the performance of his services 
pursuant to this Agreement.  Officer shall be entitled to such reimbursement 
upon the presentation by Officer to Corporation of vouchers or other 
statements itemizing such expenses in reasonable detail consistent with 
Corporation's policies.  In addition, Officer shall be entitled to 
reimbursement for (i) dues and membership fees in professional organizations 
and/or industry associations in which Officer is currently a member or 
becomes a member, and (ii) appropriate industry seminars and mandatory 
continuing education.

               (f) WITHHOLDING.  Compensation and benefits paid to Officer 
under this Agreement shall be subject to applicable federal, state and local 
wage deductions and other deductions required by law.

               (g) SIGNING BONUS.  Upon the Effective Date of this Agreement, 
Corporation shall pay Officer a lump sum cash signing bonus equal to Fifteen 
Thousand Dollars ($15,000).

     thereof specifying the nature of such willful Material Breach.  For 
     purposes of this Paragraph 4.1(b), the term willful "Material Breach" 
     shall mean the substantial and continual willful nonperformance of 
     Officer's duties under this Agreement which the Board determines has

Agreement by Officer in the event of Corporation's material breach of this 

                                       6
<PAGE>

Agreement in accordance with the provisions of this Paragraph 4.2(b) shall be 
defined as termination by Officer for "Good Reason."

               (c) GOOD REASON FOLLOWING A CHANGE IN CONTROL. Following a 
Change in Control (as defined in Paragraph 4.4(e) below), "Good Reason" shall 
mean, without Officer's express written consent, a material breach of this

     immediately prior to such change;

                    (ii)   a substantial change in the nature of the business 
     operations of Corporation;

                    (iii)  a reduction by Corporation in Officer's annual 
     base salary as in effect on the date hereof or as the same may be 
     increased from time to time;

                    (iv)   the relocation of Corporation's principal 
     executive offices to a location outside the Los Angeles metropolitan 
     area (or, if different, the metropolitan area in which such offices are 
     located immediately prior to the Change in Control), or Corporation's 
     requiring Officer to be based anywhere other than the Corporation's 
     principal executive offices except for required travel on Corporation's 
     business to an extent substantially consistent with Officer's business 
     travel obligations immediately prior to the Change in Control;

                    (v)    the failure by Corporation to pay Officer any 
     portion of his current compensation except pursuant to an 
     across-the-board compensation deferral similarly affecting all officers 
     of Corporation and all officers of any person whose actions resulted in 
     a Change in Control or any person affiliated with Corporation or such 
     person, or to pay Officer any portion of an installment of deferred 
     compensation under any deferred 

                                       7
<PAGE>

     compensation program of Corporation, within seven (7) days of the date 
     such compensation is due;

                    (vi)   the failure by Corporation to continue in effect 
     any compensation plan in which Officer participates immediately prior to 
     the Change in Control which is material to Officer's total compensation, 
     unless an equitable arrangement (embodied in an ongoing substitute or 
     alternative plan) has been made with respect to such plan, or the 
     failure by Corporation to continue Officer's participation therein (or 
     in such substitute or alternative plan) on a basis not materially less 
     favorable, both in terms of the amount of benefits provided and the 
     level of participation relative to other participants, as existed at the 
     time of the Change in Control;

                    (vii)  the failure by Corporation to continue to provide 
     Officer with benefits substantially similar to those under any of 
     Corporation's life insurance, medical, health and accident, or 
     disability plans in which Officer was participating at the time of the 
     Change in Control, the taking of any action by Corporation which would 
     directly or indirectly materially reduce any of such benefits or deprive 
     Officer of any material fringe benefit enjoyed by him at the time of the 
     Change in Control, or the failure by Corporation to provide Officer with 
     the number of paid vacation days to which he is entitled on the basis of 
     years of service with Corporation in accordance with Corporation's 
     normal vacation policy in effect at the time of the Change in Control; or

                    (viii) the failure of Corporation to obtain a 
     satisfactory agreement from any successor to assume and agree to perform 
     this Agreement.

          Officer's right to terminate Officer's employment for Good Reason 
shall not be affected by Officer's incapacity due to physical or mental 
illness. Officer's continued employment shall not constitute consent to, or a 
waiver of rights with respect to, any circumstance constituting Good Reason 
hereunder.

          4.3  EFFECT OF TERMINATION.  In the event that this Agreement is 
terminated by Corporation or Officer prior to the Termination Date in 
accordance with the provisions of this Paragraph 4, the obligations and 
covenants of the parties under this Paragraph 4 shall be of no further force 
and effect, except for the obligations of the parties set forth below in this 
Paragraph 4.3, and such other provisions of this Agreement which 

                                       8

the Severance Period; PROVIDED, HOWEVER, that in the event of a Termination 
upon a Change in Control (as defined in Paragraph 4.4(e) below), the 
Severance Payment shall be payable in a lump sum within ten (10) days

directors on the date hereof or whose appointment, election or nomination for 
election was previously so approved or recommended; or 

                    (iii)  There is consummated a merger or consolidation of 
the Corporation with any other corporation, other than (A) a merger or 
consolidation which would result in the voting securities of the Corporation 
outstanding immediately prior to such merger or consolidation continuing to 
represent (either by remaining outstanding or by being converted into voting 
securities of the surviving entity or any parent thereof), in combination 
with the ownership of any trustee or other fiduciary holding securities under 
an employee benefit plan of the Corporation or any subsidiary of the 
Corporation, at least seventy-five percent (75%) of the combined voting power 
of the securities of the Corporation or such surviving entity or any parent 
thereof outstanding immediately after such merger or consolidation, or (B) a 
merger or consolidation effected to implement a recapitalization of the 
Corporation (or similar transaction) in which no Person is or becomes the 
Beneficial Owner, directly or indirectly, of securities of the Corporation 
(not including in the securities beneficially owned by such Person any 
securities acquired directly from the Corporation or its affiliates other 
than in connection with the acquisition by the Corporation or its affiliates 
of a business) representing twenty-five percent (25%) or more of the combined 
voting power of the Corporation's then outstanding securities; or 

                    (iv)  The stockholders of the Corporation approve a plan 
of complete liquidation or dissolution of the Corporation or there is 
consummated an agreement for the sale or disposition by the Corporation of 
all or substantially all of the Corporation's assets, other than a sale or 
disposition by the Corporation of all or substantially all of the 
Corporation's assets to an entity, at least seventy-five (75%) of the 
combined voting power of the voting securities of which are owned by 
stockholders of the Corporation in substantially the same proportions as 
their ownership of the Corporation immediately prior to such sale.

     4.5  GROSS-UP. If any of the Total Payments (as hereinafter defined) 
will be subject to the tax (the "Excise Tax") imposed by Section 4999 of the 
Code, Corporation shall pay to Officer, no later than the tenth (10th) day 
following the Early Termination date, an additional amount (the "Gross-Up 
Payment") such that the net amount retained by him, after deduction of any 
Excise Tax on the Total Payments and any federal and state and local income 
tax upon the payment provided for by this Paragraph, shall be


                                      13
<PAGE>

equal to the excess of the Total Payments over the payment provided for by 
this Paragraph.  For purposes of determining whether any of the Total 
Payments will be subject to the Excise Tax and the amount of such Excise Tax, 
(i) all payments or benefits received or to be received by Officer in 
connection with a Change in Control or the termination of Officer's 
employment (whether payable pursuant to the terms of this Agreement or of any 
other plan, arrangement or agreement with Corporation, its successors, any 
person whose actions result in a Change in Control or any person affiliated 
(or which, as a result of the completion of the transactions causing a Change 
in Control, will become affiliated) with Corporation or such person within 
the meaning of Section 1504 of the Code (the "Total Payments")) Shall be 
treated as "parachute payments" (within the meaning of Section 280G(b)(2) of 
the Code) unless, in the opinion of tax counsel selected by Corporation's 
independent auditors and reasonably acceptable to Officer, such payments or 
benefits (in whole or in part) do not constitute parachute payments, 
including by reason of Section 280G(b)(4)(A) of the Code, and all "excess 
parachute payments" (within the meaning of Section 280G(b)(1) of the Code) 
shall be treated as subject to the Excise Tax, unless in the opinion of such 
tax counsel such excess parachute payments represent reasonable compensation 
for services actually rendered within the meaning of Section 280G(b)(4)(B) of 
the Code, or are not otherwise subject to the Excise Tax, and (ii) the value 
of any noncash benefits or any deferred payment or benefit shall be 
determined by the Corporation's independent auditors in accordance with the 
principles of Sections 280G(d)(3) and (4) of the Code. For purposes of 
determining the amount of the Gross-Up Payment, Officer shall be deemed to 
pay federal income taxes at the highest marginal rate of federal income 
taxation in the calendar year in which the Gross-Up Payment is to be made and 
state and local income taxes at the highest marginal rate of taxation in the 
state and locality of the residence of Officer on the Early Termination Date, 
net of the maximum reduction in federal income taxes that could be obtained 
from deduction of such state and local taxes.

     4.6  OFFSET.  Although Officer shall not be required to mitigate damages 
under this Agreement by seeking other comparable employment or otherwise, the 
amount of any payment or benefit provided for in this Agreement, including 
without limitation welfare benefits, shall be reduced by any compensation 
earned by or provided to Officer as the result of employment by an employer 
other than Corporation prior to the expiration of the term of this Agreement; 
PROVIDED, HOWEVER, that this Paragraph 4.6 shall not apply in the event of a 
Termination upon a Change in Control.

5.  NONCOMPETITION.


                                      14
<PAGE>

          During the Term of this Agreement, including the period, if any, with
respect to which Officer shall be entitled to Severance Payments, Officer shall
not engage in any activity competitive with the business of Corporation.

6.   MISCELLANEOUS.

     6.1  PAYMENT OBLIGATIONS.  Corporation's obligation to pay Officer the 
compensation and to make the arrangements provided herein shall be 
unconditional, and Officer shall have no obligation whatsoever to mitigate 
damages hereunder.  If arbitration after a Change in Control shall be brought 
to enforce or interpret any provision contained herein, Corporation shall, to 
the extent permitted by applicable law and Corporation's Articles of 
Incorporation and By-Laws, indemnify Officer for Officer's attorneys' fees 
and disbursements incurred in such arbitration.

     6.2  CONFIDENTIALITY.  Officer agrees that all confidential and 
proprietary information relating to the business of Corporation shall be kept 
and treated as confidential both during and after the Term of this Agreement, 
except as may be permitted in writing by the Board or as such information is 
within the public domain or comes within the public domain without any breach 
of this Agreement.

     6.3  WAIVER.  The waiver of the breach of any provision of this 
Agreement shall not operate or be construed as a waiver of any subsequent 
breach of the same or other provision hereof.

     6.4  ENTIRE AGREEMENT; MODIFICATIONS.  Except as otherwise provided 
herein, this Agreement (together with the agreements and plans referred to 
herein) represents the entire understanding among the parties with respect to 
the subject matter hereof, and this Agreement supersedes any and all prior 
understandings, agreements, plans and negotiations, whether written or oral, 
with respect to the subject matter hereof, including without limitation any 
understandings, agreements or obligations respecting any past or future 
compensation, bonuses, reimbursements or other payments to Officer from 
Corporation.  All modifications to the Agreement must be in writing and 
signed by the party against whom enforcement of such modification is sought.

Any Party may change such Party's address for notices by notice duly given
pursuant hereto.

     6.6  HEADINGS.  The Paragraph headings herein are intended for reference 
only and shall not by themselves determine the construction or interpretation 
of this Agreement.

     6.7  GOVERNING LAW.  Other than with respect to Paragraph 6.13 below, 
this Agreement shall be governed by and construed in accordance with the laws 
of the State of California without regard to its principles of conflict of 
laws. 

     6.8  ARBITRATION.  Any dispute arising out of or relating to this 
Agreement that cannot be settled by good faith negotiation between the 
parties shall be submitted to ENDISPUTE for final and binding arbitration 
pursuant to ENDISPUTE's Arbitration Rules incorporated herein by reference, 
which arbitration shall be the exclusive remedy of the parties hereto.  The 
resulting arbitration shall be deemed a final order of a court having 
jurisdiction over the subject matter, shall not be appealable, and shall be 
enforceable in any court of competent jurisdiction. Submission to 
arbitration, as provided in Exhibit A, shall not preclude the right of any 
party hereto involved in a dispute regarding this Agreement (each, a 
"Disputing Party" and collectively, the "Disputing Parties") to institute 
proceedings at law or in equity for injunctive or other relief pending the 
arbitration of a matter subject to arbitration pursuant to this Agreement.  
Any documentation and information submitted by any party in the arbitration 
proceeding shall be kept strictly confidential by the parties and the 
arbitrator.

     In addition to any other relief or award granted by the arbitrator to
either Disputing Party, the arbitrator shall determine the extent to which each
Disputing Party has prevailed as to the material issues raised in the
arbitration, and, based upon such 


                                      16
<PAGE>

determination, shall apportion to each Disputing Party its ratable 
share of (i) the Disputing Parties' reasonable attorneys' fees and other 
costs reasonably incurred in the arbitration, (ii) the expense of the 
arbitrator, and (iii) all other expenses of the arbitration; PROVIDED, 
HOWEVER, that any dispute following a Change in Control shall be governed by 
the provisions of Paragraph 6.1 above.  The arbitrator shall make such 
determination and apportionment whether or not the dispute proceeds to a 
final award.

     6.9  SEVERABILITY.  Should a court or other body of competent 
jurisdiction determine that any provision of this Agreement is excessive in 
scope or otherwise invalid or unenforceable, such provision shall be adjusted 
rather than voided, if possible, all other provisions of this Agreement shall 
be deemed valid and enforceable to the extent possible.

     6.10  SURVIVAL OF CORPORATION'S OBLIGATIONS. Corporation's obligations 
hereunder shall not be terminated by reason of any liquidation, dissolution, 
bankruptcy, cessation of business, or similar event relating to Corporation.  
This Agreement shall not be terminated by any merger or consolidation or 
other reorganization of Corporation.  In the event any such merger, 
consolidation or reorganization shall be accomplished by transfer of stock or 
by transfer of assets or otherwise, the provisions of this Agreement shall be 
binding upon and inure to the benefit of the surviving or resulting 
corporation or person. This Agreement shall be binding upon and inure to the 
benefit of the executors, administrators, heirs, successors and assigns of 
the parties; PROVIDED, HOWEVER, that except as herein expressly provided, 
this Agreement shall not be assignable either by Corporation (except to an 
affiliate of the Corporation, in which event Corporation shall remain liable 
if the affiliate fails to meet any obligations to make payments or provide 
benefits or otherwise) or by Officer. 

     6.11  SURVIVAL OF CERTAIN RIGHTS AND OBLIGATIONS.  The rights and 
obligations of the parties hereto pursuant to Paragraphs 4.3, 4.4, 4.5, 4.6, 
5 and 6.1, 6.2, 6.10, 6.11 and 6.13 hereof shall survive the termination of 
this Agreement.

     6.12  COUNTERPARTS.  This Agreement may be executed in one or more 
counterparts, all of which taken together shall constitute one and the same 
Agreement.

     6.13  INDEMNIFICATION.  In addition to any rights to indemnification to 
which Officer is entitled under the Corporation's Articles of Incorporation 
and By-Laws, Corporation shall indemnify Officer at all times during and 
after the Term of this Agreement to the maximum extent permitted under 
Section 2-418 of the General Corporation Law of the State of Maryland or any 
successor provision thereof and any other 


                                      17
<PAGE>

applicable state law, and shall pay Officer's expenses in defending any civil 
or criminal action, suit, or proceeding in advance of the final disposition 
of such action, suit, or proceeding, to the maximum extent permitted under 
such applicable state laws.

Parent's rights and obligations under this Agreement;

          WHEREAS, on July 30, 1996, this Agreement was amended pursuant to

          NOW, THEREFORE, in consideration of the mutual covenants contained 
herein and other good and valuable consideration, the receipt and sufficiency 
of which is hereby acknowledged, the parties hereto agree to amend and 
restate this Agreement as follows:

1.  POSITION AND DUTIES; LOCATION.

          During the Term (as defined in Paragraph 2 below) of this Agreement 
Officer agrees to be employed by and to serve Corporation as its President 
and Treasurer or in such other capacity consistent with the Officer's current 
position as senior executive officer as may be determined by the Board of 
Directors of the Corporation (the "Board").  Corporation agrees to employ and 
retain officer in such 


                                       1
<PAGE>

capacities.  Officer shall devote such of his business time, energy, and 
skill to the affairs of Corporation as shall be necessary to perform the 
duties of such positions.  Officer shall report to the Chief Operating 
Officer or such other officer as the Board shall direct, and at all times 
during the Term (as defined in Paragraph 2 below) of this Agreement shall 
have powers and duties at least commensurate with his position as a senior 
executive officer.  Officer shall be based at the offices of Corporation in 
the San Diego, California metropolitan area, except for required travel on 
Corporation's business.

2.  TERM OF EMPLOYMENT.

          The term (the "Term") of this Agreement shall be for a period 
commencing on January 1, 1997 and ending on December 31, 1998 (the 
"Termination Date"), unless terminated earlier pursuant to this Agreement 
(the "Early Termination Date").  Commencing on December 31, 1998 and on each 
subsequent anniversary thereof, the Term shall be automatically extended for 
one (1) additional year unless, no later than six (6) months before such 
date, either party shall have given written notice to the other that it does 
not wish to extend the Term of this Agreement.  References herein to the Term 
of this Agreement shall refer to both the initial Term and any such extended 
Term.

3.  COMPENSATION, BENEFITS AND REIMBURSEMENT.

         3.1 BASE SALARY.  During the Term of this Agreement, Officer shall 
be entitled to the following base salary:

               (a)  MINIMUM BASE.  During the Term of this Agreement and 
subject to the terms and conditions set forth herein, Corporation agrees to 
pay to Officer an annual "Base Salary" of One Hundred Ninety Thousand Dollars 
($190,000), or such other higher amount as may from time to time be 
determined by Corporation.  Unless otherwise agreed in writing by Officer and 
Corporation, and subject to Subparagraph (b) below, the salary shall be 
payable in substantially equal semimonthly installments in accordance with 
the standard policies of Corporation in existence from time to time.

               (b)  EARNED BASE SALARY.  For purposes of any early 
termination of this Agreement as provided in Paragraph 4 below, the term 
"Earned Base Salary" shall mean all semimonthly installments of the Base 
Salary which have become due and payable to Officer pursuant to this 
Paragraph 3.1, together with any 


                                       2
<PAGE>

partial monthly installment prorated on a daily basis up to and including the 
applicable Termination Date.

         3.2  INCREASES IN BASE SALARY.  Officer's Base Salary shall be 
reviewed no less frequently than on each anniversary of the Original 
Effective Date during the Term by the Board (or such committee as may be 
appointed by the Board for such purpose).  The Base Salary payable to Officer 
shall be increased on each such anniversary date (and such other times as the 
Board or a committee of the Board may deem appropriate during the Term of 
this Agreement) to an amount determined by the Board (or a committee of the 
Board).  Each such new Base Salary shall become the base for each successive 
year increase; PROVIDED, HOWEVER, that such increase, at a minimum, shall be 
equal to the cumulative cost-of-living increment as reported in the "Consumer 
Price Index, Los Angeles, California, All Items," published by the U.S. 
Department of Labor (using January 1, 1994 as the base date for comparison).  
Any increase in Base Salary or other compensation shall in no way limit or 
reduce any other obligations of Corporation hereunder and, once established 
at an increased specified rate, Officer's Base Salary shall not be reduced 
unless Officer otherwise agrees in writing.

         3.3  BONUS.  During the Term of this Agreement, the Officer is 
eligible for the following bonus:

               (a)  MINIMUM BONUS.  Officer shall be eligible to receive a 
bonus for each fiscal year of Corporation (or portion thereof) during the 
Term of this Agreement, with the actual amount of any such bonus to be 
determined in the sole discretion of the Board (or a committee of the Board) 
based upon its evaluation of Officer's performance during such year and such 
other factors and conditions as the Board (or a committee of the Board) deems 
relevant.  Any such bonus shall be payable within seventy-five (75) days 
after the end of Corporation's fiscal year to which such bonus relates.  The 
Board shall, at an appropriate subsequent time, consider for the benefit of 
the Officer and other specified officers of the Corporation the establishment 
of an annual incentive compensation plan providing for the payment of a 
minimum annual bonus based upon the achievement of certain objective criteria 
for the benefit of Officer and other specified executive officers of 
Corporation.

               (b)  DETERMINATION OF BONUS.  With respect to the period 
commencing upon consummation of an initial public offering (the "IPO") of the 
Corporation's common stock, par value $.01 per share (the "Common Stock"), 
and 


                                       3
<PAGE>

ending on December 31, 1997, and with respect to each calendar year 
thereafter during the Term, the bonus payable pursuant to Subparagraph (a), 
if any, shall be based upon such factors as the Board (or a committee 
thereof) deems appropriate, which may include the enhancement of stockholder 
value based upon Funds From Operations (as defined in the White Paper on 
Funds From Operations approved by the Board of Governors of the National 
Association of Real Estate Investment Trusts in March 1995) as determined in 
good faith by the Board during such period, divided by the weighted average 
number of shares of Common Stock outstanding during such period.

         3.4  ADDITIONAL BENEFITS.  During the term of this Agreement, Officer 
shall be entitled to the following additional benefits:

               (a)  OFFICER BENEFITS.  Officer shall be eligible to 
participate in such of Corporation's benefit and deferred compensation plans 
as are made available to executive officers of Corporation, including, 
without limitation, Corporation's stock incentive plans, annual incentive 
compensation plans, profit sharing/pension plans, deferred compensation 
plans, annual physical examinations, dental, vision, sick pay, and medical 
plans, personal catastrophe and accidental death insurance plans, financial 
planning and automobile arrangements, retirement plans and supplementary 
executive retirement plans, if any.  For purposes of establishing the length 
of service under any benefit plans or programs of Corporation, Officer's 
employment with the Corporation will be deemed to have commenced on the 
Original Effective Date of this Agreement. Until Corporation adopts a package 
of health and medical benefits, Corporation shall promptly reimburse Officer 
for payments made by Officer (i) with respect to the continuation of benefits 
provided by Officer's previous employer pursuant to Section 4980B ("COBRA") 
of the Internal Revenue Code of 1986, as amended (the "Code"), (ii) upon 
expiration of COBRA coverage to maintain substantially similar health and 
medical benefits coverage for Officer and his family, and (iii) if Officer is 
not covered by COBRA, to maintain reasonable health and medical benefits 
coverage for Officer and his family. 

               (b)  VACATION.  During the Term of this Agreement, Officer 
shall be entitled to four (4) weeks of vacation during each year during the 
Term of this Agreement and any extensions thereof, prorated for partial 
years. Any accrued vacation not taken during any year may be carried forward 
to subsequent years; PROVIDED that Officer may not accrue more than eight (8) 
weeks of unused vacation at any time.

                 (c)  LIFE INSURANCE.  During the Term of this Agreement, 
Corporation shall, at its sole cost and expense, procure and keep in effect 
term life insurance (a minimum three (3) year term certain policy) on the 
life of Officer, payable to such beneficiaries as Officer may from time to 
time designate, in the aggregate amount of One Million Dollars ($1,000,000).  
Such policy shall be owned by Officer or by a member of his immediate family. 
 Corporation shall have no incidents of ownership therein.

                 (d)  DISABILITY INSURANCE.  During the Term of this 
Agreement, Corporation shall, at its sole cost and expense, procure and keep 
in effect disability insurance similar to Officer's current disability 
insurance policy on Officer, payable to Officer in an annual amount not less 
than sixty percent (60%) of Officer's then existing Base Salary (the 
"Disability Policy").  For purposes of this Agreement, "Permanent Disability" 
shall have the same meaning as is ascribed to such terms in the Disability 
Policy (including the COBRA Disability Policy) covering Officer at the time 
of occurrence of such Permanent Disability.

                 (e)  REIMBURSEMENT FOR EXPENSES.  During the Term of this 
Agreement, Corporation shall reimburse Officer for all reasonable 
out-of-pocket business and/or entertainment expenses incurred by Officer for 
the purpose of and in connection with the performance of his services 
pursuant to this Agreement.  Officer shall be entitled to such reimbursement 
upon the presentation by Officer to Corporation of vouchers or other 
statements itemizing such expenses in reasonable detail consistent with 
Corporation's policies.  In addition, Officer shall be entitled to 
reimbursement for (i) dues and membership fees in professional organizations 
and/or industry associations in which Officer is currently a member or 
becomes a member, and (ii) appropriate industry seminars and mandatory 
continuing education.

                 (f)  WITHHOLDING.  Compensation and benefits paid to Officer 
under this Agreement shall be subject to applicable federal, state and local 
wage deductions and other deductions required by law.

termination specified in such notice (which date shall 
be the applicable Early Termination Date).

                 (b)  TERMINATION FOR GOOD REASON.  Subject to the provisions 
of Paragraph 4.3 below, Officer shall have the right to terminate this

of this Agreement by Officer in the event of Corporation's material breach of 
this Agreement in accordance with the provisions of this Paragraph 4.2(b) 
shall be defined as termination by Officer for "Good Reason."

                 (c)  GOOD REASON FOLLOWING A CHANGE IN CONTROL.  Following a

the position in Corporation that Officer held immediately prior to the Change 
in Control, or an adverse alteration in the nature or status of Officer's 
responsibilities from those in effect immediately prior to such change;

plan) has been made with respect to such plan, or the failure by Corporation 
to continue Officer's participation therein (or in such substitute or 
alternative plan) on a basis not materially less favorable, both in terms of 
the amount of benefits provided and the level of participation relative to 
other participants, as existed at the time of the Change in Control;

            (vi)  the failure by Corporation to continue to provide Officer 
with benefits substantially similar to those under any of Corporation's life 
insurance, medical, health and accident, or disability plans in which Officer 
was participating at the time of the Change in Control, the taking of any 
action by Corporation which would directly or indirectly materially reduce 
any of such benefits or deprive Officer of any material fringe benefit 
enjoyed by him at the time of the Change in Control, or the failure by 
Corporation to provide Officer with the number of paid vacation days to which 
he is entitled on the basis of years of service with Corporation in 
accordance with Corporation's normal vacation policy in effect at the time of 
the Change in Control; or

            (vii) the failure of Corporation to obtain a satisfactory 
agreement from any successor to assume and agree to perform this Agreement.

<PAGE>

          Officer's right to terminate Officer's employment for Good Reason 
shall not be affected by Officer's incapacity due to physical or mental 
illness. Officer's continued employment shall not constitute consent to, or a 
waiver of rights with respect to, any circumstance constituting Good Reason 
hereunder.

terminated by Corporation or Officer prior to the Termination Date in

survive termination of this Agreement as provided in Paragraph 6.11 below.  
Except as otherwise specifically set forth, all amounts due upon termination 
shall be payable on the date such amounts would otherwise have been paid had 
the Agreement continued through its Term; PROVIDED, HOWEVER, that Deferred 
Amounts (as defined in Paragraph 4.3(a)(i) below) shall be payable within 
thirty (30) days following the Early Termination Date.  In the event of any 
such early termination in accordance with the provisions of this Paragraph

          4.4  SEVERANCE PAYMENT.

                 (a)  DEFINITION OF "SEVERANCE PAYMENT." For purposes of this 
Agreement, the term "Severance Payment" shall mean an amount equal to the sum 
of (i) the Base Salary otherwise payable to Officer during the remainder of 
the Term had such early termination of this Agreement not occurred 
("Severance Period") and (ii) for each full year remaining in the Severance 
Period, the average of the annual bonuses earned by Officer in the two (2) 
years immediately preceding the date of termination (or if there are less 
than two (2) years immediately preceding such date, an amount equal to the 
immediately preceding bonus earned) ("Average Bonus"); PROVIDED, HOWEVER, 
that in the event that, following a Change in Control as defined in Paragraph 
4.4(e) below, Officer terminates this Agreement for Good Reason pursuant to 
Paragraph 4.2(b) above, the term "Severance Payment" shall mean three

                                       10

(3) times the sum of the Base Salary then in effect and the Average Bonus; 
FURTHER PROVIDED, HOWEVER, that in the event that (i) Officer's employment is 
terminated in connection with or following the Board's good faith 
determination that the possible long-run loss of Corporation may reasonably 
be expected to increase unreasonably if Corporation is not dissolved and (ii) 
such dissolution is effected in accordance with applicable law, the term 
"Severance Payment" shall mean the Base Salary then in effect, and the term 
"Severance Period" shall mean the one-year period immediately following 
Officer's date of termination of employment.

                 (b)  PAYMENT OF SEVERANCE PAYMENT.  In the event that 
Officer is entitled to any Severance Payment pursuant to Paragraph 4.3 above, 
that portion of such Severance Payment that represents Base Salary shall be 
payable in monthly installments and that portion of such Severance Payment 
that represents the Average Bonus shall be payable on the dates such amounts 
would have been paid had Officer continued in Corporation's employment for 
the Severance Period; PROVIDED, HOWEVER, that in the event of a Termination 
upon a Change in Control (as defined in Paragraph 4.4(e) below), the 
Severance Payment shall be payable in a lump sum within ten (10) days 
following such termination.

                 (c)  OTHER SEVERANCE BENEFITS.  In the event that Officer is 
entitled to any Severance Payment pursuant to Paragraph 4.3 above, he shall 
also be entitled to full and immediate vesting of any awards granted to 
Officer under Corporation's stock option or incentive compensation plans, and 
continued participation throughout the Severance Period in all employee 
welfare and pension benefit plans, programs or arrangements.  In the event 
Officer's participation in any such plan, program or arrangement is barred, 
Corporation shall arrange to provide Officer with substantially similar 
benefits.

                 (d)  FULL SETTLEMENT OF ALL OBLIGATIONS.  Officer hereby 
acknowledges and agrees that any Severance Payment paid to Officer hereunder 
shall be deemed to be in full and complete settlement of all obligations of 
Corporation under this Agreement.

"Termination Upon a Change in Control" shall mean a termination of Officer's 
employment with Corporation following a "Change in Control" by Officer for 
Good Reason or by Corporation Other Than for Cause.  A "Change in Control"

            (iv)   The stockholders of the Corporation approve a plan of 
complete liquidation or dissolution of the Corporation or there is 
consummated an agreement for the sale or disposition by the Corporation of 
all or substantially all of the Corporation's assets, other than a sale or 
disposition by the Corporation of all or substantially all of the 
Corporation's assets to an entity, at least seventy-five (75%) of the 
combined voting power of the voting securities of which are owned by 
stockholders of the Corporation in substantially the same proportions as 
their ownership of the Corporation immediately prior to such sale.

          4.5  GROSS-UP.  If any of the Total Payments (as hereinafter 
defined) will be subject to the tax imposed by Section 4999 of the Code (the 
"Excise Tax"), Corporation shall pay to Officer, no later than the tenth 
(10th) day following the Early Termination Date, an additional amount (the 
"Gross-Up Payment") such that the net amount retained by him, after deduction 
of any Excise Tax on the Total Payments and any federal and state and local 
income tax upon the payment provided for by this Paragraph, shall be equal to 
the excess of the Total Payments over the payment provided for by this 
Paragraph.  For purposes of determining whether any of the Total Payments 
will be subject to the Excise Tax and the amount of such Excise Tax, (i) all 
payments or benefits received or to be received by Officer in connection with 
a Change in Control or the termination of Officer's employment (whether 
payable pursuant to the terms of this Agreement or of any other plan, 
arrangement or agreement with Corporation, its successors, any person whose 
actions result in a Change in Control or any person affiliated (or which, as 
a result of the completion of the transactions causing a Change in Control, 
will become affiliated) with Corporation or such person within the meaning of 
Section 1504 of the Code (the "Total Payments")) shall be treated as 
"parachute payments" (within the meaning of Section 280G(b)(2) of the Code) 
unless, in the opinion of tax counsel selected by Corporation's independent 
auditors and reasonably acceptable to Officer, such payments or benefits (in 
whole or in part) do not constitute parachute payments, including by reason 
of Section 280G(b)(4)(A) of the Code, and all "excess parachute payments" 
(within the meaning of Section 280G(b)(1) of the Code) shall

                                       13
<PAGE>

be treated as subject to the Excise Tax, unless in the opinion of such tax 
counsel such excess parachute payments represent reasonable compensation for 
services actually rendered within the meaning of Section 280G(b)(4)(B) of the 
Code, or are not otherwise subject to the Excise Tax, and (ii) the value of 
any noncash benefits or any deferred payment or benefit shall be determined 
by the Corporation's independent auditors in accordance with the principles 
of Sections 280G(d)(3) and (4) of the Code. For purposes of determining the 
amount of the Gross-Up Payment, Officer shall be deemed to pay federal income 
taxes at the highest marginal rate of federal income taxation in the calendar 
year in which the Gross-Up Payment is to be made and state and local income 
taxes at the highest marginal rate of taxation in the state and locality of 
the residence of Officer on the Early Termination Date, net of the maximum 
reduction in federal income taxes that could be obtained from deduction of 
such state and local taxes.

          4.6  OFFSET.  Although Officer shall not be required to mitigate 
damages under this Agreement by seeking other comparable employment or 
otherwise, the amount of any payment or benefit provided for in this 
Agreement, including, without limitation, welfare benefits, shall be reduced 
by any compensation earned by or provided to Officer as the result of 
employment by an employer other than Corporation prior to the expiration of 
the Term of this Agreement; PROVIDED, HOWEVER, that this Paragraph 4.6 shall 
not apply in the event of a Termination Upon a Change in Control.

5.  NONCOMPETITION.

          During the Term of this Agreement, including the period, if any, with
respect to which Officer shall be entitled to Severance Payments, Officer shall
not engage in any activity competitive with the business of Corporation.

6.  MISCELLANEOUS.

          6.1  PAYMENT OBLIGATIONS.  Corporation's obligation to pay Officer 
the compensation and to make the arrangements provided herein shall be 
unconditional, and Officer shall have no obligation whatsoever to mitigate 
damages hereunder.  If arbitration after a Change in Control shall be brought 
to enforce or interpret any provision contained herein, Corporation shall, to 
the extent permitted by applicable law and Corporation's Articles of 
Incorporation and By-Laws, indemnify Officer for Officer's attorneys' fees 
and disbursements incurred in such arbitration. 0

proprietary information relating to the business of Corporation shall be kept

within the public domain or comes within the public domain without any breach 
of this Agreement.

          6.3  WAIVER.  The waiver of the breach of any provision of this 
Agreement shall not operate or be construed as a waiver of any subsequent

herein, this Agreement (together with the agreements and plans referred to 
herein) represents the entire understanding among the parties with respect to 
the subject matter hereof, and this Agreement supersedes any and all prior 
understandings, agreements, plans and negotiations, whether written or oral, 
with respect to the subject matter hereof, including without limitation any 
understandings, agreements or obligations respecting any past or future 
compensation, bonuses, reimbursements or other payments to Officer from 
Corporation.  All modifications to the Agreement must be in writing and 
signed by the party against whom enforcement of such modification is sought.

          6.6  HEADINGS.  The Paragraph headings herein are intended for 
reference only and shall not by themselves determine the construction or 
interpretation of this Agreement.

          6.7  ARBITRATION.  Any dispute arising out of or relating to this 
Agreement that cannot be settled by good faith negotiation between the 
parties shall be submitted to ENDISPUTE for final and binding arbitration 
pursuant to ENDISPUTE's Arbitration Rules incorporated herein by reference, 
which arbitration shall be the exclusive remedy of the parties hereto.  The 
resulting arbitration shall be deemed a final order of a court having 
jurisdiction over the subject matter, shall not be appealable, and shall be 
enforceable in any court of competent jurisdiction.  Submission to 
arbitration, as provided in Exhibit A, shall not preclude the right of any 
party hereto involved in a dispute regarding this Agreement (each, a 
"Disputing Party" and collectively, the "Disputing Parties") to institute 
proceedings at law or in equity for injunctive or other relief pending the 
arbitration of a matter subject to arbitration pursuant to this Agreement.  
Any documentation and information submitted by any party in the arbitration 
proceeding shall be kept strictly confidential by the parties and the 
arbitrator.

          In addition to any other relief or award granted by the arbitrator 
to either Disputing Party, the arbitrator shall determine the extent to which 
each Disputing Party has prevailed as to the material issues raised in the 
arbitration, and, based upon such determination, shall apportion to each 
Disputing Party its ratable share of (i) the Disputing Parties' reasonable 
attorneys' fees and other costs reasonably incurred in the arbitration, (ii) 
the expense of the arbitrator, and (iii) all other expenses of the 
arbitration; PROVIDED, HOWEVER, that any dispute following a Change in 
Control shall be governed by the provisions of Paragraph 6.1 above.  The 
arbitrator shall make such determination and apportionment whether or not the 
dispute proceeds to a final award.

          6.8  SEVERABILITY.  Should a court or other body of competent 
jurisdiction determine that any provision of this Agreement is excessive in 
scope or otherwise invalid or unenforceable, such provision shall be adjusted 
rather than voided, if possible, and all other provisions of this Agreement 
shall be deemed valid and enforceable to the lawfully permitted.

          6.9  SURVIVAL OF CORPORATION'S OBLIGATIONS. Corporation's 
obligations hereunder shall not be terminated by reason of any liquidation, 
dissolution, bankruptcy, cessation of business, or similar event relating to 
Corporation.  This Agreement shall not be terminated by any merger or 
consolidation or other reorganization of Corporation.  In the event any such 
merger, consolidation or reorganization shall be accomplished by transfer of 
stock or by transfer of assets or otherwise, the provisions of this Agreement 
shall be binding upon and inure to the benefit of the surviving or resulting 
corporation or person.  This Agreement shall be binding upon and inure to the 
benefit of the executors, administrators, heirs, successors and assigns of 
the parties; PROVIDED, HOWEVER, that except as herein expressly provided, 
this Agreement shall not be assignable either by Corporation (except to an 
affiliate of the Corporation, in which event Corporation shall remain liable 
if the affiliate fails to meet any obligations to make payments or provide 
benefits or otherwise) or by Officer.

          6.10  SURVIVAL OF CERTAIN RIGHTS AND OBLIGATIONS.  The rights and 
obligations of the parties hereto pursuant to Paragraphs 4.3, 4.4, 4.5, 4.6, 
5 and 6.1, 6.2, 6.10, 6.11 and 6.13 hereof shall survive the termination of 
this Agreement.

          6.11  COUNTERPARTS.  This Agreement may be executed in one or more 
counterparts, all of which taken together shall constitute one and the same 
Agreement.

          6.12  INDEMNIFICATION.  In addition to any rights to 
indemnification to which Officer is entitled under the Corporation's Articles 
of Incorporation and By-Laws, Corporation shall indemnify Officer at all 
times during and after the Term of this Agreement to the maximum extent 
permitted under Section 2-418 of the General Corporation Law of the State of 
Maryland or any successor provision thereof and any other applicable state 
law, and shall pay Officer's expenses in defending any civil or criminal 
action, suit, or proceeding in advance of the final disposition of such 
action, suit, or proceeding, to the maximum extent permitted under such 
applicable state laws.

                              AMENDED AND RESTATED
                         EXECUTIVE EMPLOYMENT AGREEMENT


          THIS AMENDED AND RESTATED EXECUTIVE EMPLOYMENT AGREEMENT (this
"Agreement") originally made and entered into as of the fifth (5th) day of
January, 1994, (the "Original Effective Date"), by and between Health Science
Properties Holding Corp., a Maryland corporation (the "Parent") and Gary A.
Kreitzer, an individual (the "Officer") is hereby amended and restated in its
entirety effective as of March 28, 1997 (the "Effective Date") to read as
follows:

                                    RECITAL

          WHEREAS, on November 3, 1994, Parent transferred to its then 
wholly-owned subsidiary Alexandria Real Estate Equities, Inc., a Maryland 
corporation (formerly, Health Science Properties, Inc.) (the "Corporation") 
substantially all of its property, assets and certain liabilities, including 
Parent's rights and obligations under this Agreement;

          WHEREAS, on July 30, 1996, this Agreement was amended pursuant to 
an agreement between the Corporation and Officer;

          WHEREAS, Corporation desires to continue to employ Officer as its 
Senior Vice President and In-House Counsel, and Officer is willing to 
continue to accept such employment by Corporation, on the terms and subject 
to the conditions set forth in this Agreement.

          NOW, THEREFORE, in consideration of the mutual covenants contained 
herein and for other good and valuable consideration, the receipt and 
sufficiency of which is hereby acknowledged, the parties hereto agree to 
amend and restate this Agreement as follows:

1.   POSITION AND DUTIES; LOCATION.

          During the Term (as defined in Paragraph 2 below) of this Agreement,
Officer agrees to be employed by and to serve Corporation as its Senior Vice
President and In-House Counsel or in such other capacity consistent with the
Officer's current position as a senior executive officer, as may be determined
by the Board of Directors of the Corporation (the "Board").  Corporation agrees
to employ and retain Officer in such capacities.  Officer shall devote such of
his business time, energy, and skill to the affairs of Corporation as shall be


                                      1

<PAGE>

necessary to perform the duties of such positions.  Officer shall report to the
President or such other officer as the Board shall direct, and at all times
during the Term (as defined in Paragraph 2 below) of this Agreement shall have
powers and duties at least commensurate with his position as a senior executive
officer.  Officer shall be based at the offices of Corporation in the San Diego,
California metropolitan area, except for required travel on Corporation's
business.

2.   TERM OF EMPLOYMENT.

          The term (the "Term") of this Agreement shall be for a period 
commencing January 1, 1997 and ending on December 31, 1998 (the "Termination 
Date"), unless terminated earlier pursuant to this Agreement (the "Early 
Termination Date").  Commencing on December 31, 1998 and on each subsequent 
anniversary thereof, the Term shall be automatically extended for one (1) 
additional year unless, no later than six (6) months before such date, either 
party shall have given written notice to the other that it does not wish to 
extend the Term of this Agreement.  References herein to the Term of this 
Agreement shall refer to both the initial Term and any such extended Term.

3.   COMPENSATION, BENEFITS AND REIMBURSEMENT.

          3.1  BASE SALARY.  During the Term of this Agreement, Officer shall 
be entitled to the following base salary:

          (a)  MINIMUM BASE.  During the Term of this Agreement and subject 
to the terms and conditions set forth herein, Corporation agrees to pay to 
Officer an annual "Base Salary" of One Hundred Forty Thousand Dollars 
($140,000) or such higher amount as may from time to time be determined by 
Corporation.  Unless otherwise agreed to in writing by Officer and 
Corporation, and subject to Subparagraph (b) below, the salary shall be 
payable in substantially equal semimonthly installments in accordance with 
the standard policies of Corporation in existence from time to time.

          (b)  EARNED BASE SALARY.  For purposes of any early termination of 
this Agreement as provided in Paragraph 4 below, the term "Earned Base 
Salary" shall mean all semimonthly installments of the Base Salary which have 
become due and payable to Officer together with any partial monthly 
installment prorated on a daily basis up to and including the applicable 
Termination Date.

          3.2  INCREASES IN BASE SALARY.  Officer's Base Salary shall be 
reviewed no less frequently than on each anniversary of the Original 
Effective Date during the Term by the 


                                      2

<PAGE>

Board (or such committee as may be appointed by the Board for such purpose).  
The Base Salary payable to Officer shall be increased on each such 
anniversary date (and such other times as the Board or a committee of the 
Board may deem appropriate during the Term of this Agreement) by an amount 
determined by the Board (or a committee of the Board).  Each such new Base 
Salary shall become the base for each successive year increase; PROVIDED, 
HOWEVER, that, at a minimum, such increase shall be equal to the cumulative 
cost-of-living increment as reported in the "Consumer Price Index, Los 
Angeles, California, All Items," published by the U.S. Department of Labor 
(using January 1, 1994, as the base date for comparison).  Any increase in 
Base Salary or other compensation shall in no way limit or reduce any other 
obligations of Corporation hereunder and, once established at an increased 
specified rate, Officer's Base Salary shall not be reduced unless Officer 
otherwise agrees in writing.

           3.3  BONUS.  Officer shall be eligible to receive a bonus for each 
fiscal year of Corporation (or portion thereof) during the Term of this 
Agreement, with the actual amount of any such bonus to be determined in the 
sole discretion of the Board (or a committee of the Board) based upon its 
evaluation of Officer's performance during such year and such other factors 
and conditions as the Board (or a committee of the Board) deems relevant.  
Any such bonus shall be payable within seventy-five (75) days after the end 
of Corporation's fiscal year to which such bonus relates.  The Board shall, 
at an appropriate subsequent time, consider for the benefit of Officer and 
other specified executive officers of the Corporation the establishment of an 
annual incentive compensation plan providing for the payment of a minimum 
annual bonus based upon the achievement of certain objective criteria. 

           3.4  ADDITIONAL BENEFITS.  During the Term of this Agreement, 
Officer shall be entitled to the following additional benefits:

           (a)  OFFICER BENEFITS.  Officer shall be eligible to participate 
in such of Corporation's benefit and deferred compensation plans as are made 
available to executive officers of Corporation, including, without 
limitation, Corporation's stock incentive plans, annual incentive 
compensation plans, profit sharing/pension plans, deferred compensation 
plans, annual physical examinations, dental, vision, sick pay, and medical 
plans, personal catastrophe and accidental death insurance plans, financial 
planning and automobile arrangements, retirement plans and supplementary 
executive retirement plans, if any.  For purposes of establishing the length 
of service under any benefit plans or programs of Corporation, Officer's 
employment with the Corporation will be deemed to have commenced on the 
Original Effective Date of this Agreement. Until Corporation adopts a package 
of health and medical benefits, Corporation shall promptly reimburse Officer 
for payments made by Officer (i) with respect to the continuation of benefits 
provided by Officer's previous employer pursuant to Section 4980B ("COBRA") 
of the Internal Revenue Code of 1986, as amended (the 


                                      3

<PAGE>

"Code"), (ii) upon expiration of COBRA coverage to maintain substantially 
similar health and medical benefits coverage for Officer and his family, and 
(iii) if Officer is not covered by COBRA, to maintain reasonable health and 
medical benefits coverage for Officer and his family. 

          (b)  VACATION.  During the Term of this Agreement, Officer shall be 
entitled to four (4) weeks of vacation during each year during the Term of 
this Agreement and any extensions thereof, prorated for partial years.  Any 
accrued vacation not taken during any year may be carried forward to 
subsequent years; PROVIDED that Officer may not accrue more than eight (8) 
weeks of unused vacation at any time.

          (c)  LIFE INSURANCE.  During the Term of this Agreement, 
Corporation shall, at its sole cost and expense, procure and keep in effect 
term life insurance (a minimum three (3) year term certain policy) on the 
life of Officer, payable to such beneficiaries as Officer may from time to 
time designate, in the aggregate amount of One Million Dollars ($1,000,000).  
Such policy shall be owned by Officer or by a member of his immediate family. 
Corporation shall have no incidents of ownership therein.

          (d)  DISABILITY INSURANCE.  During the Term of this Agreement, 
Corporation shall, at its sole cost and expense, procure and keep in effect 
disability insurance similar to Officer's current disability insurance policy 
on Officer, payable to Officer in an annual amount not less than sixty 
percent (60%) of Officer's then-existing Base Salary (the "Disability 
Policy").  For purposes of this Agreement, "Permanent Disability" shall have 
the same meaning as is ascribed to such terms in the Disability Policy 
(including the COBRA Disability Policy) covering Officer at the time of

4.   TERMINATION OF THE AGREEMENT.

          4.1  TERMINATION BY CORPORATION DEFINED.

          (a)  TERMINATION WITHOUT CAUSE.  Subject to the provisions set 
forth in Paragraph 4.3 below, "Termination Without Cause" shall constitute 
any termination by Corporation other than termination for Cause (as defined 
in Paragraph 4.1(b) below).

          (b)  TERMINATION FOR CAUSE.  Subject to the provisions set forth in 
Paragraph 4.3 below, prior to the Termination Date, Corporation shall have 
the right to terminate this Agreement for Cause immediately after written 
notice has been delivered to Officer, which notice shall specify the reason 
for and the effective date of such Termination (which date shall be the 
applicable Early Termination Date).  For purposes of this Agreement, "Cause" 
shall mean the following:

               (i)   Officer's use of alcohol or narcotics which proximately 
     results in the willful material breach or habitual willful neglect of 
     Officer's duties under this Agreement;

               (ii)  Officer's criminal conviction of fraud, embezzlement, 
     misappropriation of assets, malicious mischief, or any felony;

               (iii) Officer's willful Material Breach (as defined below) of 
     this Agreement, if such willful Material Breach is not cured by Officer 
     within thirty (30) days after Corporation's written notice thereof 
     specifying the nature of such willful Material Breach.  For purposes of 
     this Paragraph 4.1(b), the term willful "Material Breach" shall mean the 
     substantial and continual willful nonperformance of Officer's duties 
     under this Agreement which the Board determines has resulted in material 
     injury to Corporation.

          (c)  TERMINATION BY REASON OF DEATH OR DISABILITY.  Subject to the 
provisions set forth in Paragraph 4.3 below, prior to the Termination Date, 
Corporation shall have the right to terminate this Agreement by reason of

          4.2  TERMINATION BY OFFICER DEFINED.

          (a)  TERMINATION OTHER THAN FOR GOOD REASON.  Subject to the 
provisions set forth in Paragraph 4.3 below, Officer shall have the right to 
terminate this Agreement for any reason other than for Good Reason (as 
defined in Paragraph 4.2(b) below), at any time prior to the Termination 
Date, upon written notice delivered to Corporation thirty (30) days prior to 
the effective date of termination specified in such notice (which date shall 
be the applicable Early Termination Date).

          (b)  TERMINATION FOR GOOD REASON.  Subject to the provisions of 
Paragraph 4.3 below, Officer shall have the right to terminate this Agreement 
prior to the Termination Date in the event of the material breach of this 
Agreement by Corporation, if such breach is not cured by Corporation within 
thirty (30) days after written notice thereof specifying the nature of such 
breach has been delivered to Corporation, or, following a Change in Control 
(as defined in Paragraph 4.4(e) below), under the circumstances set forth in 
Paragraph 4.2(c) below.  For purposes of this Agreement, termination of this 
Agreement by Officer in the event of Corporation's material breach of this 
Agreement in accordance with the provisions of this Paragraph 4.2(b) shall be 
defined as termination by Officer for "Good Reason."

          (c)  GOOD REASON FOLLOWING A CHANGE IN CONTROL.  Following a Change 
in Control (as defined in Paragraph 4.4(e) below), "Good Reason" shall mean, 
without Officer's express written consent, a material breach of this 
Agreement by Corporation, including the occurrence of any of the following 
circumstances, which breach is not fully corrected within thirty (30) days 
after written notice thereof specifying the nature of such breach has been 
delivered to Corporation:

               (a)  the assignment to Officer of any duties inconsistent with
the position in Corporation that Officer held immediately prior to the Change in
Control, or an adverse alteration in the nature or status of Officer's
responsibilities from those in effect immediately prior to such change;

as in effect on the date hereof or as the same may be increased from time to
time;

               (c)  the relocation of Officer's offices to a location outside
the San Diego metropolitan area (or, if different, the metropolitan area in
which such offices are located immediately prior to the Change in Control) or
Corporation's requiring Officer to travel on Corporation's business to an extent
not substantially consistent with Officer's business travel obligations
immediately prior to the Change in Control;


                                       6


<PAGE>


               (d)  the failure by Corporation to pay Officer any portion of 
his current compensation except pursuant to an across-the-board compensation 
deferral similarly affecting all officers of Corporation and all officers of 
any person whose actions resulted in a Change in Control or any person 
affiliated with Corporation or such person, or to pay Officer any portion of 
an installment of deferred compensation under any deferred compensation 
program of Corporation, within seven (7) days of the date such compensation 
is due;

               (e)  the failure by Corporation to continue in effect any 
compensation plan in which Officer participates immediately prior to the 
Change in Control which is material to Officer's total compensation, unless 
an equitable arrangement (embodied in an ongoing substitute or alternative 
plan) has been made with respect to such plan, or the failure by Corporation 
to continue Officer's participation therein (or in such substitute or 
alternative plan) on a basis not materially less favorable, both in terms of 
the amount of benefits provided and the level of participation relative to 
other participants, as existed at the time of the Change in Control;

               (f)  the failure by Corporation to continue to provide Officer 
with benefits substantially similar to those under any of Corporation's life 
insurance, medical, health and accident, or disability plans in which Officer 
was participating at the time of the Change in Control, the taking of any 
action by Corporation which would directly or indirectly materially reduce 
any of such benefits or deprive Officer of any material fringe benefit 
enjoyed by him at the time of the Change in Control, or the failure by 
Corporation to provide Officer with the number of paid vacation days to which 
he is entitled on the basis of years of service with Corporation in 
accordance with Corporation's normal vacation policy, in effect at the time 
of the Change in Control; or

               (g)  the failure of Corporation to obtain a satisfactory
agreement from any successor to assume and agree to perform this Agreement.

          Officer's right to terminate Officer's employment for Good Reason 
shall not be affected by Officer's incapacity due to physical or mental 
illness. Officer's continued employment shall not constitute consent to, or a 
waiver of rights with respect to, any circumstance constituting Good Reason 
hereunder.

          4.3  EFFECT OF TERMINATION.  In the event that this Agreement is 
terminated by Corporation or Officer prior to the Termination Date in 
accordance with the provisions of this Paragraph 4, the obligations and 
covenants of the parties under this Paragraph 4 shall be of no further force 
and effect, except for the obligations of the parties set forth below in this 
Paragraph 4.3, and such other provisions of this Agreement which shall 
survive termination of 


                                       7


<PAGE>


this Agreement as provided in Paragraph 6.11 below.  Except as otherwise 
specifically set forth, all amounts due upon termination shall be payable on 
the date such amounts would otherwise have been paid had the Agreement 
continued through its Term; PROVIDED, HOWEVER, that Deferred Amounts (as 
defined in Paragraph 4.3(a)(i) below) shall be payable within thirty (30) 
days following the Early Termination Date.  In the event of any such early 
termination in accordance with the provisions of this Paragraph 4.3, Officer 
shall be entitled to the following:

          (a)  TERMINATION BY CORPORATION.

               (i)  TERMINATION WITHOUT CAUSE.  In the event that Corporation
terminates this Agreement without Cause pursuant to Paragraph 4.1(a) above,
Officer shall be entitled to (i) Earned Base Salary; (ii) earned benefits and
reimbursable expenses; (iii) any earned bonus which Officer has been awarded
pursuant to the terms of this Agreement or any other plan or arrangement as of
the Early Termination Date, but which has not been received by Officer as of
such date; (iv) any compensation earned but deferred ("Deferred Amounts"); and
(v) the Severance Payment (as defined in Paragraph 4.4 below).

               (ii) TERMINATION FOR CAUSE, DEATH OR PERMANENT DISABILITY.  In
the event that Corporation terminates this Agreement for Cause pursuant to
Paragraph 4.1(b) above or by reason of Permanent Disability or death pursuant to
Paragraph 4.1(c) above, Officer shall be entitled to (i) Earned Base Salary;
(ii) any earned bonus which Officer has been awarded pursuant to the terms of
this Agreement or any other plan or arrangement as of the Early Termination
Date, but which has not been received by Officer as of such date; (iii) earned
benefits and reimbursable expenses; and (iv) any Deferred Amounts.  Officer
shall not be entitled to any future annual bonus or Severance Payment.

          (b)  TERMINATION BY OFFICER.

               (i)  TERMINATION OTHER THAN FOR GOOD REASON.  In the event that
Officer terminates this Agreement other than for Good Reason, Officer shall be
entitled to (i) Earned Base Salary; (ii) any earned bonus which Officer has been
awarded pursuant to the terms of this Agreement or any other plan or arrangement
as of the Early Termination Date, but which has not been received by Officer as
of such date; (iii) earned benefits and reimbursable expenses; and (iv) any
Deferred Amounts.  Officer shall not be entitled to any future annual bonus or
Severance Payment.

               (ii) TERMINATION FOR GOOD REASON.  In the event that Officer
terminates this Agreement for Good Reason, Officer shall be entitled to (i)
Earned Base Salary; (ii) earned benefits and reimbursable expenses; (iii) any
earned bonus which Officer 


                                       8


<PAGE>


has been awarded pursuant to the terms of this Agreement or any other plan or 
arrangement as of the Early Termination Date, but which has not been received 
by Officer as of such date; (iv) any Deferred Amounts; and (v) the Severance 
Payment (as defined in Paragraph 4.4 below).

          4.4  SEVERANCE PAYMENT.

               (a)  DEFINITION OF "SEVERANCE PAYMENT."  For purposes of this 
Agreement, the term "Severance Payment" shall mean an amount equal to the sum 
of (i) the Base Salary otherwise payable to Officer during the remainder of 
the Term had such early termination of this Agreement not occurred (the 
"Severance Period") and (ii) for each full year remaining in the Severance 
Period, the average of the annual bonuses earned by Officer in the two (2) 
years immediately preceding the date of termination (or if there are less 
than two (2) years immediately preceding such date, an amount equal to the 
immediately preceding bonus earned) (the "Average Bonus"); PROVIDED, HOWEVER, 
that in the event that, following a Change in Control (as defined in 
Paragraph 4.4(e) below), Officer terminates this Agreement for Good Reason 
pursuant to Paragraph 4.2(b) above, the term "Severance Payment" shall mean 
three (3) times the sum of the Base Salary then in effect and the Average 
Bonus; FURTHER, PROVIDED, HOWEVER, that in the event that (i) Officer's 
employment is terminated in connection with or following the Board's good 
faith determination that the possible long-run loss of Corporation may 
reasonably be expected to increase unreasonably if Corporation is not 
dissolved and (ii) such dissolution is effected in accordance with applicable 
law, the term "Severance Payment" shall mean the Base Salary then in effect, 
and the term "Severance Period" shall mean the one-year period immediately 
following Officer's date of termination of employment.

          (b)  PAYMENT OF SEVERANCE PAYMENT.  In the event that Officer is 
entitled to any Severance Payment pursuant to Paragraph 4.3 above, that 
portion of such Severance Payment that represents Base Salary shall be 
payable in monthly installments, and that portion of such Severance Payment 
that represents the Average Bonus shall be payable on the dates such amounts 
would have been paid had Officer continued in Corporation's employment for 
the Severance Period; PROVIDED, HOWEVER, that in the event of a Termination 
upon a Change in Control (as defined in Paragraph 4.4(e) below), the 
Severance Payment shall be payable in a lump sum within ten (10) days 
following such termination.

          (c)  OTHER SEVERANCE BENEFITS.  In the event that Officer is 
entitled to any Severance Payment pursuant to Paragraph 4.3 above, he shall 
also be entitled to full and 


                                       9


<PAGE>


immediate vesting of any awards granted to Officer under Corporation's stock 
option or incentive compensation plans, and continued participation 
throughout the Severance Period in all employee welfare and pension benefit 
plans, programs or arrangements.  In the event Officer's participation in any 
such plan, program or arrangement is barred, Corporation shall arrange to 
provide Officer with substantially similar benefits.

          (d)  FULL SETTLEMENT OF ALL OBLIGATIONS.  Officer hereby acknowledges 
and agrees that any Severance Payment paid to Officer hereunder shall be 
deemed to be in full and complete settlement of all obligations of 
Corporation under this Agreement.

          (e)  CHANGE IN CONTROL.  For purposes of this Agreement, "Termination 
Upon a Change in Control" shall mean a termination of Officer's employment 
with Corporation following a "Change in Control" by Officer for Good Reason 
or by Corporation Other Than for Cause.  A "Change in Control" shall be 
deemed to have occurred if:

in Rule 13d-3 under the Exchange Act, directly or indirectly, of securities of

Person any securities acquired directly from the Corporation or its affiliates
other than in connection with the acquisition by the Corporation or its
affiliates of a business) representing twenty-five percent (25%) or more of the
combined voting power of the Corporation's then outstanding securities; or 

                    (ii)  The following individuals cease for any reason to
constitute a majority of the number of directors then serving:  individuals who,
on the date hereof, constitute the Board and any new director (other than a

solicitation, relating to the election of directors of the Corporation) whose
appointment or election by the Board or nomination for election by the
Corporation's stockholders was approved or recommended by a vote of at least
two-thirds (2/3) of the directors then still in 


                                       10


<PAGE>


office who either were directors on the date hereof or whose appointment, 
election or nomination for election was previously so approved or 
recommended; or 

                    (iii)  There is consummated a merger or consolidation of 
the Corporation with any other corporation, other than (A) a merger or 
consolidation which would result in the voting securities of the Corporation 
outstanding immediately prior to such merger or consolidation continuing to 
represent (either by remaining outstanding or by being converted into voting 
securities of the surviving entity or any parent thereof), in combination 
with the ownership of any trustee or other fiduciary holding securities under 
an employee benefit plan of the Corporation or any subsidiary of the 
Corporation, at least seventy-five percent (75%) of the combined voting power 
of the securities of the Corporation or such surviving entity or any parent 
thereof outstanding immediately after such merger or consolidation, or (B) a 
merger or consolidation effected to implement a recapitalization of the 
Corporation (or similar transaction) in which no Person is or becomes the 
Beneficial Owner, directly or indirectly, of securities of the Corporation 
(not including in the securities beneficially owned by such Person any 
securities acquired directly from the Corporation or its affiliates other 
than in connection with the acquisition by the Corporation or its affiliates

combined voting power of the voting securities of which are owned by

their ownership of the Corporation immediately prior to such sale.

          4.5  GROSS-UP.  If any of the Total Payments (as hereinafter 
defined) will be subject to the tax imposed by Section 4999 of the Code (the 
"Excise Tax"), Corporation shall pay to Officer, no later than the tenth 
(10th) day following the Early Termination Date, an additional amount (the 
"Gross-Up Payment") such that the net amount retained by him, after deduction 
of any Excise Tax on the Total Payments and any federal and state and local 
income tax upon the payment provided for by this Paragraph, shall be equal to 
the excess of the Total Payments over the payment provided for by this 
Paragraph.  For purposes of determining whether any of the Total Payments 
will be subject to the Excise Tax and the amount of such Excise Tax, (i) all 
payments or benefits received or to be received by Officer in connection with 
a Change in Control or the termination of Officer's employment (whether 
payable pursuant to the terms of this Agreement or of any other plan, 
arrangement or agreement with 


                                       11








<PAGE>

Corporation, its successors, any person whose actions result in a Change in 
Control or any person affiliated (or which, as a result of the completion of 
the transactions causing a Change in Control, will become affiliated) with 
Corporation or such person within the meaning of Section 1504 of the Code 
(the "Total Payments")) shall be treated as "parachute payments" (within the 
meaning of Section 280G(b)(2) of the Code) unless, in the opinion of tax 
counsel selected by Corporation's independent auditors and reasonably 
acceptable to Officer, such payments or benefits (in whole or in part) do not 
constitute parachute payments, including by reason of Section 280G(b)(4)(A) 
of the Code, and all "excess parachute payments" (within the meaning of 
Section 280G(b)(1) of the Code) shall be treated as subject to the Excise 
Tax, unless in the opinion of such tax counsel such excess parachute payments 
represent reasonable compensation for services actually rendered within the 
meaning of Section 280G(b)(4)(B) of the Code, or are not otherwise subject to 
the Excise Tax, and (ii) the value of any noncash benefits or any deferred 
payment or benefit shall be determined by the Corporation's independent 
auditors in accordance with the principles of Sections 280G(d)(3) and (4) of 
the Code. For purposes of determining the amount of the Gross-Up Payment, 
Officer shall be deemed to pay federal income taxes at the highest marginal 
rate of federal income taxation in the calendar year in which the Gross-Up 
Payment is to be made and state and local income taxes at the highest 
marginal rate of taxation in the state and locality of the residence of 
Officer on the Early Termination Date, net of the maximum reduction in 
federal income taxes that could be obtained from deduction of such state and 
local taxes.

          4.6 OFFSET.  Although Officer shall not be required to mitigate 
damages under this Agreement by seeking other comparable employment or 
otherwise, the amount of any payment or benefit provided for in this 
Agreement, including, without limitation, welfare benefits, shall be reduced 
by any compensation earned by or provided to Officer as the result of 
employment by an employer other than Corporation prior to the expiration of 
the Term of this Agreement; PROVIDED, HOWEVER, that this Paragraph 4.6 shall 
not apply in the event of a Termination Upon a Change in Control.

5.  NONCOMPETITION.

          During the Term of this Agreement, including the period, if any, with
respect to which Officer shall be entitled to Severance Payments, Officer shall
not engage in any activity competitive with the business of Corporation.

6.  MISCELLANEOUS.

          6.1 PAYMENT OBLIGATIONS.  Corporation's obligation to pay Officer the 
compensation and to make the arrangements provided herein shall be 
unconditional, and 


                                       12


<PAGE>


Officer shall have no obligation whatsoever to mitigate damages hereunder.  
If arbitration after a Change in Control shall be brought to enforce or

permitted by applicable law and Corporation's Articles of Incorporation and 
By-Laws, indemnify Officer for Officer's attorneys' fees and disbursements 
incurred in such arbitration.

          6.2 CONFIDENTIALITY.  Officer agrees that all confidential and 
proprietary information relating to the business of Corporation shall be kept

within the public domain or comes within the public domain without any breach 
of this Agreement.

          6.3 WAIVER.  The waiver of the breach of any provision of this 
Agreement shall not operate or be construed as a waiver of any subsequent 
breach of the same or other provision hereof.

herein, this Agreement (together with the agreements and plans referred to 
herein) represents the entire understanding among the parties with respect to 
the subject matter hereof, and this Agreement supersedes any and all prior

the laws of the State of California without regard to its principles of 
conflict of laws.

          6.8 ARBITRATION.  Any dispute arising out of or relating to this 
Agreement that cannot be settled by good faith negotiation between the 
parties shall be submitted to ENDISPUTE for final and binding arbitration 
pursuant to ENDISPUTE's Arbitration Rules incorporated herein by reference,

resulting arbitration shall be deemed a final order of a court having 
jurisdiction over the subject matter, shall not be appealable, and shall be

arbitration of a matter subject to arbitration pursuant to this Agreement.

proceeding shall be kept strictly confidential by the parties and the 
arbitrator.

          In addition to any other relief or award granted by the arbitrator

each Disputing Party has prevailed as to the material issues raised in the 
arbitration, and, based upon such determination, shall apportion to each 
Disputing Party its ratable share of (i) the Disputing Parties' reasonable 
attorneys' fees and other costs reasonably incurred in the arbitration, (ii) 
the expense of the arbitrator, and (iii) all other expenses of the

arbitrator shall make such determination and apportionment whether or not the 
dispute proceeds to a final award.

          6.9 SEVERABILITY.  Should a court or other body of competent 
jurisdiction determine that any provision of this Agreement is excessive in 
scope or otherwise invalid or unenforceable, such provision shall be adjusted 
rather than voided, if possible, and all other 


                                       14


<PAGE>


provisions of this Agreement shall be deemed valid and enforceable to the

consolidation or other reorganization of Corporation.  In the event any such 
merger, consolidation or reorganization shall be accomplished by transfer of

shall be binding upon and inure to the benefit of the surviving or resulting 
corporation or person. This Agreement shall be binding upon and inure to the 
benefit of the executors, administrators, heirs, successors and assigns of

this Agreement shall not be assignable either by Corporation (except to an 
affiliate of the Corporation, in which event Corporation shall remain liable 
if the affiliate fails to meet any obligations to make payments or provide 
benefits or otherwise) or by Officer.

          6.11 SURVIVAL OF CERTAIN RIGHTS AND OBLIGATIONS.  The rights and 
obligations of the parties hereto pursuant to Paragraphs 4.3, 4.4, 4.5, 4.6,

Agreement.

          6.13 INDEMNIFICATION.  In addition to any rights to indemnification 
to which Officer is entitled under the Corporation's Articles of 
Incorporation and By-Laws, Corporation shall indemnify Officer at all times 
during and after the Term of this Agreement to the maximum extent permitted 
under Section 2-418 of the General Corporation Law of the State of Maryland

                 AMENDED AND RESTATED EXECUTIVE EMPLOYMENT AGREEMENT


          THIS AMENDED AND RESTATED EXECUTIVE EMPLOYMENT AGREEMENT (this
"Agreement") originally made and entered into as of the fifth (5th) day of
January, 1994, (the "Original Effective Date"), by and between Health Science
Properties Holding Corp., a Maryland corporation (the "Parent") and Steven A.
Stone, an individual (the "Officer") is hereby amended and restated in its
entirety effective as of March 28, 1997 (the "Effective Date") to read as
follows:

                                       RECITAL

          WHEREAS, on November 3, 1994, Parent transferred to its then wholly-
owned subsidiary Alexandria Real Estate Equities, Inc., a Maryland corporation
(formerly, Health Science Properties, Inc.) (the "Corporation") substantially
all of its property, assets and certain liabilities, including Parent's rights
and obligations under this Agreement;

          WHEREAS, on July 30, 1996, this Agreement was amended pursuant to an
agreement between the Corporation and Officer;

          WHEREAS, Corporation desires to continue to employ Officer as its Vice
President, and Officer is willing to continue to accept such employment by
Corporation, on the terms and subject to the conditions set forth in this
Agreement.

          NOW, THEREFORE, in consideration of the mutual covenants contained
herein and other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, the parties hereto agree to amend and restate this
Agreement as follows:

POSITION AND DUTIES; LOCATION.

          During the Term (as defined in Paragraph 2 below) of this Agreement,
Officer agrees to be employed by and to serve Corporation as its Vice President
or in such other capacity consistent with the Officer's current position as a
senior executive officer as may be determined by the Board of Directors of the
Corporation (the "Board").  Corporation agrees to employ and retain Officer in
such capacities.  Officer shall devote such of his business time, energy, and
skill to the affairs of Corporation as shall be necessary to perform the duties
of such positions.  Officer shall report to the President or such other officer
as the Board shall direct, and at all times during the Term (as defined in
Paragraph 2 below) of this Agreement


                                       1
<PAGE>

shall have powers and duties at least commensurate with his position as a senior
executive officer.  Officer shall be based at the offices of Corporation in the
San Diego, California metropolitan area, except for required travel on
Corporation's business.

2.  TERM OF EMPLOYMENT.

          The term (the "Term") of this Agreement shall be for a period
commencing on January 1, 1997 and ending on December 31, 1998 (the "Termination
Date"), unless terminated earlier pursuant to this Agreement (the "Early
Termination Date").  Commencing on December 31, 1998 and on each subsequent
anniversary thereof, the Term shall be automatically extended for one (1)
additional year unless, no later than six (6) months before such date, either
party shall have given written notice to the other that it does not wish to
extend the Term of this Agreement.  References herein to the Term of this
Agreement shall refer to both the initial Term and any such extended Term.  

3.  COMPENSATION, BENEFITS AND REIMBURSEMENT.

          3.1 BASE SALARY.  During the Term of this Agreement, Officer shall be
entitled to the following base salary:

          (a) MINIMUM BASE.  During the Term of this Agreement and subject to
the terms and conditions set forth herein, Corporation agrees to pay to Officer
an annual "Base Salary" of One Hundred Five Thousand Dollars ($105,000), or such
higher amount as may from time to time be determined by Corporation.  Unless 
otherwise agreed in writing by Officer and Corporation, and subject to
Subparagraph (b) below, the salary shall be payable in substantially equal
semimonthly installments in accordance with the standard policies of  
Corporation inexistence from time to time. 

          (b) EARNED BASE SALARY.  For purposes of any early termination of this
Agreement as provided in Paragraph 4 below, the term "Earned Base Salary" shall
mean all semimonthly installments of the Base Salary which have become due and
payable to Officer together with any partial monthly installment prorated on a
daily basis up to and including the applicable Termination Date.

          3.2 INCREASES IN BASE SALARY.  Officer's Base Salary shall be reviewed
no less frequently than on each anniversary of the Original Effective Date
during the Term by the Board (or such committee as may be appointed by the Board
for such purpose).  The Base Salary payable to Officer shall be increased on 
each such anniversary date (and such other times as the Board or a committee of 
the Board may deem appropriate during the Term of this


                                       2
<PAGE>

Agreement) to an amount determined by the Board (or a committee of the Board).
Each such new Base Salary shall become the base for each successive year
increase; PROVIDED, HOWEVER, that such increase, at a minimum, shall be equal to
the cumulative cost-of-living increment as reported in the "Consumer Price 
Index, Los Angeles, California, All Items," published by the U.S. Department of 
Labor (using January 1, 1994 as the base date for comparison).  Any increase in 
Base Salary or other compensation shall in no way limit or reduce any other 
obligations of Corporation hereunder and, once established at an increased 
specified rate, Officer's Base Salary shall not be reduced unless Officer 
otherwise agrees in writing.

          3.3 BONUS.  Officer shall be eligible to receive a bonus for each 
fiscal year of Corporation (or portion thereof) during the Term of this 
Agreement, with the actual amount of any such bonus to be determined in the 
sole discretion of the Board (or a committee of the Board) based upon its 
evaluation of Officer's performance during such year and such other factors and 
conditions as the Board (or a committee of the Board) deems relevant.  Any such 
bonus shall be payable within seventy-five (75) days after the end of 
Corporation's fiscal year to which such bonus relates.  The Board shall, at an 
appropriate subsequent time, consider for the benefit of Officer and other 
specified executive officers of the Corporation the establishment of an annual 
incentive compensation plan providing for the payment of a minimum annual bonus 
based upon the achievement of certain objective criteria for the benefit of 
Officer and other specified executive officers of Corporation.

          3.4 ADDITIONAL BENEFITS.  During the Term of this Agreement, Officer 
shall be entitled to the following additional benefits:

          (a) OFFICER BENEFITS.  Officer shall be eligible to participate in 
such of Corporation's benefit and deferred compensation plans as are made 
available to executive officers of Corporation, including, without limitation, 
Corporation's stock incentive plans, annual incentive compensation plans, profit
sharing/pension plans, deferred compensation plans, annual physical
examinations, dental, vision, sick pay, and medical plans, personal catastrophe
and accidental death insurance plans, financial planning and automobile
arrangements, retirement plans and supplementary executive retirement plans, if
any.  For purposes of establishing the length of service under any benefit plans
or programs of Corporation, Officer's employment with the Corporation will be
deemed to have commenced on the Original Effective Date of this Agreement. 
Until Corporation adopts a package of health and medical benefits, Corporation
shall promptly reimburse Officer for payments made by Officer (i) with respect
to the continuation of benefits provided by Officer's previous employer pursuant
to Section 4980B ("COBRA") of the Internal Revenue Code of 1986, as amended (the
"Code"), (ii) upon expiration of COBRA coverage to maintain substantially
similar health and medical benefits coverage for Officer and his family, and
(iii) if Officer is not covered by 


                                       3
<PAGE>

COBRA, to maintain reasonable health and medical benefits coverage for Officer 
and his family. 

          (b) VACATION.  During the Term of this Agreement, Officer shall be 
entitled to four (4) weeks of vacation during each year during the Term of this 
Agreement and any extensions thereof, prorated for partial years. Any accrued 
vacation not taken during any year may be carried forward to subsequent years; 
PROVIDED that Officer may not accrue more than eight (8) weeks of unused 
vacation at any time.

          (c) LIFE INSURANCE.  During the Term of this Agreement, Corporation 
shall, at its sole cost and expense, procure and keep in effect term life 
insurance (a minimum three (3) year term certain policy) on the life of 
Officer, payable to such beneficiaries as Officer may from time-to-time 
designate, in the aggregate amount of One Million Dollars ($1,000,000).  Such 
policy shall be owned by Officer or by a member of his immediate family.  
Corporation shall have no incidents of ownership therein.

          (d) DISABILITY INSURANCE.  During the Term of this Agreement, 
Corporation shall, at its sole cost and expense, procure and keep in effect 
disability insurance similar to Officer's current disability insurance policy 
on Officer, payable to Officer in an annual amount not less than sixty percent 
(60%) of Officer's then existing Base Salary (the "Disability Policy").  For 
purposes of this Agreement,"Permanent Disability" shall have the same meaning 
as is ascribed to such terms in the Disability Policy (including the COBRA 
Disability Policy) covering Officer at the time of occurrence of such Permanent 
Disability.

          (e) REIMBURSEMENT FOR EXPENSES.  During the Term of this Agreement, 
Corporation shall reimburse Officer for all reasonable out-of-pocket business 
and/or entertainment expenses incurred by Officer for the purpose of and in 
connection with the performance of his services pursuant to this Agreement.  
Officer shall be entitled to such reimbursement upon the presentation by Officer
to Corporation of vouchers or other statements itemizing such expenses in
reasonable detail consistent with Corporation's policies.  In addition, Officer
shall be entitled to reimbursement for (i) dues and membership fees in
professional organizations and/or industry associations in which Officer is
currently a member or becomes a member, and (ii) appropriate industry seminars
and mandatory continuing education.

          (f) WITHHOLDING.  Compensation and benefits paid to Officer under this
Agreement shall be subject to applicable federal, state and local wage 
deductions and other deductions required by law.

4.  TERMINATION OF THE AGREEMENT.

          4.1 TERMINATION BY CORPORATION DEFINED.

          (a) TERMINATION WITHOUT CAUSE.  Subject to the provisions set forth in
Paragraph 4.3 below, "Termination Without Cause" shall constitute any 
termination by Corporation other than termination for Cause (as defined in 
Paragraph 4.1(b) below).

          (b) TERMINATION FOR CAUSE.  Subject to the provisions set forth in 
Paragraph 4.3 below, prior to the Termination Date, Corporation shall have the 
right to terminate this Agreement for Cause immediately after written notice has
been delivered to Officer, which notice shall specify the reason for and the
effective date of such Termination (which date shall be the applicable Early
Termination Date).  For purposes of this Agreement, "Cause" shall mean the
following:

                (i)   Officer's use of alcohol or narcotics which proximately 
results in the willful material breach or habitual willful neglect of Officer's 
duties under this Agreement;

                (ii)  Officer's criminal conviction of fraud, embezzlement, 
misappropriation of assets, malicious mischief, or any felony;

                (iii) Officer's willful Material Breach (as defined below) of 
this Agreement, if such willful Material Breach is not cured by Officer within 
thirty (30) days after Corporation's written notice thereof specifying the 
nature of such willful Material Breach.  For purposes of this Paragraph 4.1(b), 
the term willful "Material Breach" shall mean the substantial and continual 
willful nonperformance of Officer's duties under this Agreement which the Board
determines has resulted in material injury to Corporation.

          (c) TERMINATION BY REASON OF DEATH OR DISABILITY.  Subject to the 
provisions set forth in Paragraph 4.3 below, prior to the Termination Date, 
Corporation shall have the right to terminate this Agreement by reason of 
Officer's death or Permanent Disability.

          4.2 TERMINATION BY OFFICER DEFINED.

          (a) TERMINATION OTHER THAN FOR GOOD REASON.  Subject to the provisions
set forth in Paragraph 4.3 below, Officer shall have the right to terminate this
Agreement for any reason other than for Good Reason (as defined in Paragraph 
4.2(b) below), at any time prior to the Termination Date, upon written notice 
delivered to Corporation thirty (30) days prior to 

                                       5
<PAGE>

the effective date of termination specified in such notice (which date shall 
be the applicable Early Termination Date).

          (b)  TERMINATION FOR GOOD REASON.  Subject to the provisions of 
Paragraph 4.3 below, Officer shall have the right to terminate this Agreement 
prior to the Termination Date in the event of the material breach of this 
Agreement by Corporation, if such breach is not cured by Corporation within 
thirty (30) days after written notice thereof specifying the nature of such 
breach has been delivered to Corporation or following a Change in Control (as 
defined in Paragraph 4.4(e) below), under the circumstances set forth in 
Paragraph 4.2(c) below.  For purposes of this Agreement, termination of this 
Agreement by Officer in the event of Corporation's material breach of this 
Agreement in accordance with the provisions of this Paragraph 4.2(b) shall be 
defined as termination by Officer for "Good Reason."

          (c)  GOOD REASON FOLLOWING A CHANGE IN CONTROL.  Following a Change 
in Control (as defined in Paragraph 4.4(e) below), "Good Reason" shall mean, 
without Officer's express written consent, a material breach of this 
Agreement by Corporation, including the occurrence of any of the following 
circumstances, which breach is not fully corrected within thirty (30) days 
after written notice thereof specifying the nature of such breach has been 
delivered to Corporation:

               (a)  the assignment to Officer of any duties inconsistent with 
the position in Corporation that Officer held immediately prior to the Change 
in Control, or an adverse alteration in the nature or status of Officer's 
responsibilities from those in effect immediately prior to such change;

               (b)  a reduction by Corporation in Officer's annual base 
salary as in effect on the date hereof or as the same may be increased from 
time-to-time;

               (c)  the relocation of Officer's offices to a location outside 
the San Diego metropolitan area (or, if different, the metropolitan area in 
which such offices are located immediately prior to the Change in Control) or 
Corporation's requiring Officer to travel on Corporation's business to an 
extent not substantially consistent with Officer's business travel 
obligations immediately prior to the Change in Control;

               (d)  the failure by Corporation to pay Officer any portion of 
his current compensation except pursuant to an across-the-board compensation 
deferral similarly affecting all officers of Corporation and all officers of 
any person whose actions resulted in a Change in Control or any person 
affiliated with Corporation or such person, or to pay Officer 

                                        6

<PAGE>

any portion of an installment of deferred compensation under any deferred 
compensation program of Corporation, within seven (7) days of the date such 
compensation is due;

               (e)  the failure by Corporation to continue in effect any 
compensation plan in which Officer participates immediately prior to the 
Change in Control which is material to Officer's total compensation, unless 
an equitable arrangement (embodied in an ongoing substitute or alternative 
plan) has been made with respect to such plan, or the failure by Corporation 
to continue Officer's participation therein (or in such substitute or 
alternative plan) on a basis not materially less favorable, both in terms of 
the amount of benefits provided and the level of participation relative to 
other participants, as existed at the time of the Change in Control;

               (f)  the failure by Corporation to continue to provide Officer 
with benefits substantially similar to those under any of Corporation's life 
insurance, medical, health and accident, or disability plans in which Officer 
was participating at the time of the Change in Control, the taking of any 
action by Corporation which would directly or indirectly materially reduce 
any of such benefits or deprive Officer of any material fringe benefit 
enjoyed by him at the time of the Change in Control, or the failure by 
Corporation to provide Officer with the number of paid vacation days to which 
he is entitled on the basis of years of service with Corporation in 
accordance with Corporation's normal vacation policy in effect at the time of 
the Change in Control; or
              
               (g)  the failure of Corporation to obtain a satisfactory 
agreement from any successor to assume and agree to perform this Agreement.

          Officer's right to terminate Officer's employment for Good Reason 
shall not be affected by Officer's incapacity due to physical or mental 
illness. Officer's continued employment shall not constitute consent to, or a 
waiver of rights with respect to, any circumstance constituting Good Reason 
hereunder.

          4.3   EFFECT OF TERMINATION.  In the event that this Agreement is 
terminated by Corporation or Officer prior to the Termination Date in 
accordance with the provisions of this Paragraph 4, the obligations and 
covenants of the parties under Paragraph 4 shall be of no further force and 
effect, except for the obligations of the parties set forth below in this 
Paragraph 4.3, and such other provisions of this Agreement which shall 
survive termination of this Agreement as provided in Paragraph 6.11 below.  
Except as otherwise specifically set forth, all amounts due upon termination 
shall be payable on the date such amounts would otherwise have been paid had 
the Agreement continued through its Term; PROVIDED, HOWEVER, that Deferred 
Amounts (as defined in Paragraph 4.3(a)(i) below) shall be payable within 
thirty 

                                        7

<PAGE>

(30) days following the Early Termination Date.  In the event of any such 
early termination in accordance with the provisions of this Paragraph 4.3, 
Officer shall be entitled to the following:

         4.4  SEVERANCE PAYMENT.

         (a)  DEFINITION OF "SEVERANCE PAYMENT."  For purposes of this 
Agreement, the term "Severance Payment" shall mean an amount equal to the sum 
of (i) the Base Salary otherwise payable to Officer during the remainder of 
the Term had such early termination of this Agreement not occurred (the 
"Severance Period") and (ii) for each full year remaining in the Severance 
Period, the average of the annual bonuses earned by Officer in the two (2) 
years immediately preceding the date of termination (or if there are less 
than two (2) years immediately preceding such date, an amount equal to the 
immediately preceding bonus earned) (the "Average Bonus"); PROVIDED, HOWEVER, 
that in the event that, following a Change in Control (as defined in 
Paragraph 4.4(e) below), Officer terminates this Agreement for Good Reason 
pursuant to Paragraph 4.2(b) above, the term "Severance Payment" shall mean 
three (3) times the sum of the Base Salary then in effect and the Average 
Bonus; FURTHER PROVIDED, HOWEVER, that in the event that (i) Officer's 
employment is terminated in connection with or following the Board's good 
faith determination that the possible long-run loss of Corporation may 
reasonably be expected to increase unreasonably if Corporation is not 
dissolved and (ii) such dissolution is effected in accordance with applicable 
law, the term "Severance Payment" shall mean the Base Salary then in effect, 
and the term "Severance Period" shall mean the one-year period immediately 
following Officer's date of termination of employment.

         (b)  PAYMENT OF SEVERANCE PAYMENT.  In the event that Officer is 
entitled to any Severance Payment pursuant to Paragraph 4.3 above, that 
portion of such Severance Payment that represents Base Salary shall be 
payable in monthly installments, and that portion of such Severance Payment 
that represents the Average Bonus shall be payable on the dates such amounts 
would have been paid had Officer continued in Corporation's employment for 
the Severance Period; PROVIDED, HOWEVER, that in the event of a Termination 
upon a Change in Control (as defined in Paragraph 4.4(e) below), the 
Severance Payment shall be payable in a lump sum within ten (10) days 
following such termination.

         (c)  OTHER SEVERANCE BENEFITS.  In the event that Officer is 
entitled to any Severance Payment pursuant to Paragraph 4.3 above, he shall 
also be entitled to full and immediate vesting of any awards granted to 
Officer under Corporation's stock option or incentive compensation plans, and 
continued participation throughout the Severance Period in all employee 
welfare and pension benefit plans, programs or arrangements.  In the event 
Officer's participation in any such plan, program or arrangement is barred, 
Corporation shall arrange to provide Officer with substantially similar 
benefits.

         (d)  FULL SETTLEMENT OF ALL OBLIGATIONS.  Officer hereby 
acknowledges and agrees that any Severance Payment paid to Officer hereunder 
shall be deemed to be in full and complete settlement of all obligations of 
Corporation under this Agreement.

         (e)  CHANGE IN CONTROL.  For purposes of this Agreement, 
"Termination Upon a Change in Control" shall mean a termination of Officer's 
employment with Corporation following a "Change in Control" by Officer for 
Good Reason or by Corporation Other Than for Cause.  A "Change in Control" 
shall be deemed to have occurred if:

except that such term shall not include (A) the Corporation or any of its 
subsidiaries, (B) a trustee or other fiduciary holding securities under an 
employee benefit plan of the Corporation or any of its affiliates, (C) an 
underwriter temporarily holding securities pursuant to an offering of such

Owner, as such term is defined in Rule 13d-3 under the Exchange Act, directly 
or indirectly, of securities of the Corporation (not including in the 
securities beneficially owned by such Person any securities acquired directly 
from the Corporation or its affiliates other than in connection with the 
acquisition by the Corporation or its affiliates of a business) representing 
twenty-five percent (25%) or more of the combined voting power of the 
Corporation's then outstanding securities; or 

                    (ii)  The following individuals cease for any reason to 
constitute a majority of the number of directors then serving:  individuals 
who, on the date hereof, constitute the Board and any new director (other 
than a director whose initial assumption of office is in connection with an 
actual or threatened election contest, including but not limited to a consent 
solicitation, relating to the election of directors of the Corporation) whose 
appointment or election by the Board or nomination for election by the 
Corporation's stockholders was approved or recommended by a vote of at least 
two-thirds (2/3) of the directors then still in office who either were

immediately prior to such merger or consolidation continuing to represent
(either by remaining outstanding or by being con-

                                        10
<PAGE>

verted into voting securities of the surviving entity or any parent thereof), 
in combination with the ownership of any trustee or other fiduciary holding 
securities under an employee benefit plan of the Corporation or any 
subsidiary of the Corporation, at least seventy-five percent (75%) of the 
combined voting power of the securities of the Corporation or such surviving 
entity or any parent thereof outstanding immediately after such merger or 
consolidation, or (B) a merger or consolidation effected to implement a 
recapitalization of the Corporation (or similar transaction) in which no 
Person is or becomes the Beneficial Owner, directly or indirectly, of 
securities of the Corporation (not including in the securities beneficially 
owned by such Person any securities acquired directly from the Corporation or 
its affiliates other than in connection with the acquisition by the 
Corporation or its affiliates of a business) representing twenty-five percent 
(25%) or more of the combined voting power of the Corporation's then 
outstanding securities; or 

                    (iv)  The stockholders of the Corporation approve a plan 
of complete liquidation or dissolution of the Corporation or there is 
consummated an agreement for the sale or disposition by the Corporation of 
all or substantially all of the Corporation's assets, other than a sale or

Corporation's assets to an entity, at least seventy-five (75%) of the 
combined voting power of the voting securities of which are owned by 
stockholders of the Corporation in substantially the same proportions as 
their ownership of the Corporation immediately prior to such sale.

         4.5  GROSS-UP.  If any of the Total Payments (as hereinafter 
defined) will be subject to the tax  imposed by Section 4999 of the Code (the 
"Excise Tax"), Corporation shall pay to Officer, no later than the tenth 
(10th) day following the Early Termination Date, an additional amount (the 
"Gross-Up Payment") such that the net amount retained by him, after deduction 
of any Excise Tax on the Total Payments and any federal and state and local 
income tax upon the payment provided for by this Paragraph, shall be equal to 
the excess of the Total Payments over the payment provided for by this 
Paragraph.  For purposes of determining whether any of the Total Payments 
will be subject to the Excise Tax and the amount of such Excise Tax, (i) all 
payments or benefits received or to be received by Officer in connection with 
a Change in Control or the termination of Officer's employment (whether 
payable pursuant to the terms of this Agreement or of any other plan, 
arrangement or agreement with Corporation, its successors, any person whose 
actions result in a Change in Control or any person affiliated (or which, as 
a result of the completion of the transactions causing a Change in Control, 
will become affiliated) with Corporation or such person within the meaning of 
Section 1504 of the Code (the "Total Payments")) shall be treated as 
"parachute payments" (within the meaning of Section 280G(b)(2) of the Code) 
unless, in the opinion of tax counsel selected by Corporation's independent 
auditors and reasonably acceptable to Officer, such payments or benefits (in 
whole or in part) do not constitute parachute payments, including by 

                                        11
<PAGE>

reason of Section 280G(b)(4)(A) of the Code, and all "excess parachute 
payments" (within the meaning of Section 280G(b)(l) of the Code) shall be 
treated as subject to the Excise Tax, unless in the opinion of such tax 
counsel such excess parachute payments represent reasonable compensation for 
services actually rendered within the meaning of Section 280G(b)(4)(B) of the 
Code, or are not otherwise subject to the Excise Tax, and (ii) the value of 
any noncash benefits or any deferred payment or benefit shall be determined 
by the Corporation's independent auditors in accordance with the principles 
of Sections 280G(d)(3) and (4) of the Code. For purposes of determining the 
amount of the Gross-Up Payment, Officer shall be deemed to pay federal income 
taxes at the highest marginal rate of federal income taxation in the calendar 
year in which the Gross-Up Payment is to be made and state and local income 
taxes at the highest marginal rate of taxation in the state and locality of 
the residence of Officer on the Early Termination Date, net of the maximum 
reduction in federal income taxes that could be obtained from deduction of 
such state and local taxes.

         4.6  OFFSET.  Although Officer shall not be required to mitigate 
damages under this Agreement by seeking other comparable employment or 
otherwise, the amount of any payment or benefit provided for in this 
Agreement, including without limitation welfare benefits, shall be reduced by 
any compensation earned by or provided to Officer as the result of employment 
by an employer other than Corporation prior to the expiration of the Term of 
this Agreement; PROVIDED, HOWEVER, that this Paragraph 4.6 shall not apply in 
the event of a Termination Upon a Change in Control.

5.   NONCOMPETITION.

          During the Term of this Agreement, including the period, if any, 
with respect to which Officer shall be entitled to Severance Payments, 
Officer shall not engage in any activity competitive with the business of 
Corporation.

6.   MISCELLANEOUS.

         6.1  PAYMENT OBLIGATIONS.  Corporation's obligation to pay Officer 
the compensation and to make the arrangements provided herein shall be 
unconditional, and Officer shall have no obligation whatsoever to mitigate 
damages hereunder.  If arbitration after a Change in Control shall be brought 
to enforce or interpret any provision contained herein, Corporation shall, to 
the extent permitted by applicable law and Corporation's Articles of 
Incorporation and By-Laws, indemnify Officer for Officer's attorneys' fees 
and disbursements incurred in such arbitration.

within the public domain or comes within the public domain without any breach 
of this Agreement.

herein, this Agreement (together with the agreements and plans referred to 
herein) represents the entire understanding among the parties with respect to

reference only and shall not by themselves determine the construction or 
interpretation of this Agreement.

         6.7  GOVERNING LAW.  Other than with respect to Paragraph 6.13 
below, this Agreement shall be governed by and construed in accordance with 
the laws of the State of California without regard to its principles of

Agreement that cannot be settled by good faith negotiation between the 
parties shall be submitted to ENDISPUTE for final and binding arbitration 
pursuant to ENDISPUTE's Arbitration Rules incorporated herein by reference, 
which arbitration shall be the exclusive remedy of the parties hereto.  The 
resulting arbitration shall be deemed a final order of a court having 
jurisdiction over the subject matter, shall not be appealable, and shall be 
enforceable in any court of competent jurisdiction. Submission to 
arbitration, as provided in Exhibit A, shall not preclude the right of any 
party hereto involved in a dispute regarding this Agreement (each a 
"Disputing Party" and collectively, the "Disputing Parties") to institute 
proceedings at law or in equity for injunctive or other relief pending the 
arbitration of a matter subject to arbitration pursuant to this Agreement.

proceeding shall be kept strictly confidential by the parties and the 
arbitrator.

          In addition to any other relief or award granted by the arbitrator

each Disputing Party has prevailed as to the material issues raised in the 
arbitration, and, based upon such determination, shall apportion to each 
Disputing Party its ratable share of (i) the Disputing Parties' reasonable 
attorneys' fees and other costs reasonably incurred in the arbitration, (ii) 
the expense of the arbitrator, and (iii) all other expenses of the 
arbitration; PROVIDED, HOWEVER, that any dispute following a Change in 
Control shall be governed by the provisions of Paragraph 6.1 above.  The 
arbitrator shall make such determination and apportionment whether or not the 
dispute proceeds to a final award.

         6.9  SEVERABILITY.  Should a court or other body of competent 
jurisdiction determine that any provision of this Agreement is excessive in 
scope or otherwise invalid or unenforceable, such provision shall be adjusted

shall be deemed valid and enforceable to the lawfully permitted.

         6.10 SURVIVAL OF CORPORATION'S OBLIGATIONS.  Corporation's 
obligations hereunder shall not be terminated by reason of any liquidation,

Corporation.  This Agreement shall not be terminated by any merger or 
consolidation or other reorganization of Corporation.  In the 

                                        14
<PAGE>

event any such merger, consolidation or reorganization shall be accomplished 
by transfer of stock or by transfer of assets or otherwise, the provisions of 
this Agreement shall be binding upon and inure to the benefit of the 
surviving or resulting corporation or person. This Agreement shall be binding 
upon and inure to the benefit of the executors, administrators, heirs, 
successors and assigns of the parties; PROVIDED, HOWEVER, that except as 
herein expressly provided, this Agreement shall not be assignable either by 
Corporation (except to an affiliate of the Corporation, in which event 
Corporation shall remain liable if the affiliate fails to meet any 
obligations to make payments or provide benefits or otherwise) or by Officer.

         6.11 SURVIVAL OF CERTAIN RIGHTS AND OBLIGATIONS.  The rights and 
obligations of the parties hereto pursuant to Paragraphs 4.3, 4.4, 4.5, 4.6, 
5 and 6.1, 6.2, 6.10, 6.11 and 6.13 hereof shall survive the termination of 
this Agreement.

         6.12 COUNTERPARTS.  This Agreement may be executed in one or more 
counterparts, all of which taken together shall constitute one and the same 
Agreement.

         6.13 INDEMNIFICATION.  In addition to any rights to indemnification 
to which Officer is entitled under the Corporation's Articles of 
Incorporation and Bylaws, Corporation shall indemnify Officer at all times 
during and after the Term of this Agreement to the maximum extent permitted 
under Section 2-418 of the General Corporation Law of the State of Maryland 
or any successor provision thereof and any other applicable state law, and 
shall pay Officer's expenses in defending any civil or criminal action, suit, 
or proceeding in advance of the final disposition of such action, suit, or 
proceeding, to the maximum extent permitted under such applicable state laws.

                   SECOND AMENDMENT TO THE EXECUTIVE EMPLOYMENT
                    AGREEMENT AND GENERAL AND SPECIAL RELEASE


          This Second Amendment to the Executive Employment Agreement and 
General and Special Release (this "Second Amendment and Release") is entered 
into as of this 30th day of May, 1997, by and between ALEXANDRIA REAL ESTATE 
EQUITIES, INC., a Maryland corporation (formerly known as Health Science 
Properties, Inc.) (the "Corporation"), and JERRY M. SUDARSKY, an individual 
(the "Officer") (collectively, the "Parties").

          WHEREAS, Officer originally entered into that certain Executive 
Employment Agreement (the "Employment Agreement"), dated as of June 9, 1994, 
with Health Science Properties Holding Corporation (the "Parent"), and on 
November 3, 1994, Parent transferred to the Corporation substantially all of 
its property, assets and certain liabilities, including Parent's rights and 
obligations under the Employment Agreement;

          WHEREAS, on July 30, 1996, the Parties amended the Employment 
Agreement by execution of that certain First Amendment to the Employment 
Agreement Between Health Science Properties, Inc. And Jerry M. Sudarsky, 
pursuant to which the Corporation agreed to employ Officer as its Chairman of 
the Board of Directors (the "Chairman") and Chief Executive Officer until 
December 31, 2000;

          WHEREAS, on March 14, 1997, Officer resigned from the position of 
Chief Executive Officer of the Corporation and currently serves as full-time 
executive Chairman of the Corporation; and

          WHEREAS, upon consummation of an initial public offering by the 
Corporation of its common stock (the "IPO"), Officer desires to retire from 
employment with the Corporation and thereafter to serve as non-executive 
Chairman of the Corporation and perform the duties consistent with such 
position for the duration of his term as Chairman, which expires at the next 
annual election of officers.

          NOW, THEREFORE, in consideration of the mutual covenants and 
agreements contained herein, and for good and valuable consideration, the 
receipt and sufficiency of which are hereby acknowledged, the Parties hereto 
agree as follows:

<PAGE>

          1.   AMENDMENTS TO EMPLOYMENT AGREEMENT.

               a. OFFICER'S RETIREMENT; TERMINATION OF EMPLOYMENT AGREEMENT. 
Effective upon consummation of the IPO, Officer shall voluntarily retire from 
employment with the Corporation.  Except as expressly provided herein, all of 
the Corporation's duties and obligations under the Employment Agreement shall 
terminate effective as of the date of Officer's retirement.  Officer 
acknowledges and agrees that his voluntary retirement pursuant to this Second 
Amendment and Release is not, and shall not be treated as, a Termination for 
Good Reason pursuant to Section 4.2 of the Employment Agreement.

               b. RETIREMENT BENEFITS.  Section 3.5(e) of the Employment 
Agreement is hereby amended in its entirety to read as follows:  

     "(e) RETIREMENT BENEFIT.  Commencing on the date of consummation of the 
     IPO, the Company shall pay Officer an annual retirement benefit equal to 
     One Hundred Fifty Thousand Dollars ($150,000) per year for a period of 
     three (3) years, and, thereafter, shall pay Officer an annual retirement 
     benefit equal to Ninety Thousand Dollars ($90,000) per year as provided 
     herein; PROVIDED, HOWEVER, that commencing June 1 of the year following 
     the year in which the retirement benefit is reduced to Ninety Thousand 
     Dollars ($90,000) per year, the amount of the retirement benefit shall 
     be increased by 2% per year on June 1 of each year thereafter.  The 
     benefit shall be payable monthly, beginning on the first day of the 
     month following the month in which consummation of the IPO occurs and 
     shall be payable in the form of a 100% joint and survivor annuity on the 
     lives of Officer and Officer's spouse as of the date hereof, if then 
     living; PROVIDED, HOWEVER that in the event of a Change in Control (as 
     defined in Section 4.4(d) of this  Employment Agreement), the

     purchase of an annuity contract that provides Officer with the benefit 
     described in this Paragraph 3.5(e).   In the event of Officer's death 
     prior to the commencement of the retirement benefit under this Paragraph 
     3.5(e), Officer's spouse as of the date hereof, if then living, shall be 
     entitled to receive, commencing on the first day of the month next 
     following Officer's death, the retirement benefit, the Officer's spouse 
     as of the date hereof, would have received had Officer retired and 
     commenced receiving benefits immediately prior to his death. Amounts 
     payable under this Paragraph 3.5(e) shall be offset by any amounts paid 
     to Officer under any Disability Policy maintained by the Corporation."

Section 1(b), above), 5, 6.1, 6.2, 6.3, 6.8, 6.10, 6.11, and 6.13 of the 
Employment Agreement shall survive the termination of that agreement.

          2.   STATUS AS CHAIRMAN OF THE BOARD OF DIRECTORS.  The execution 
of this Second Amendment and Release shall not preclude Officer from serving 
as, and the Corporation hereby acknowledges that it intends to continue to 
retain Officer as, non-executive Chairman performing the duties consistent 
with such position at least for the remainder of his term as Chairman, which 
expires at the next annual election of officers.

          3.   RELEASE OF CLAIMS AND OTHER MATTERS.

               a.   OFFICER'S GENERAL AND SPECIAL RELEASE. In consideration 
of the benefits provided to Officer pursuant to this Second Amendment and 
Release, Officer hereby forever releases and discharges the Corporation, its 
parent, subsidiary and affiliated corporations, and each of their respective 
present and former officers, directors, managers, agents, employees, and 
attorneys, and their successors and assigns (collectively, the "Released 
Parties") from any and all claims, charges, complaints, liens, demands, 
causes of action, obligations, damages and liabilities, KNOWN OR UNKNOWN, 
SUSPECTED OR UNSUSPECTED, that Officer had, now has, or may hereafter claim 
to have against the Released Parties, arising out of or relating in any way 
to Officer's employment with or his separation from the Corporation, any and 
all alleged acts or omissions of any of the Released Parties, and any other 
claim relating to any of the Released Parties from the beginning of time 
through the effective date of Officer's resignation from the Corporation 
pursuant to Section 1(a), above.  This release specifically extends to, 
without limitation, claims or causes of action for wrongful termination, 
impairment of ability to compete in the open labor market, breach of an 
express or implied contract, breach of the covenant of good faith and fair 
dealing, breach of fiduciary duty, fraud, misrepresentation, defamation,

         SETTLEMENT WITH THE DEBTOR.

Notwithstanding the provisions of Section 1542, and for the purpose of 
implementing a full and complete release, Officer understands and agrees that 
this Second Amendment and Release is intended to include all claims, if any, 
that Officer may have which he does not now know or suspect to exist in his 
favor against the Released Parties and this Second Amendment and Release 
extinguishes those claims.

          4.   REVIEW AND REVOCATION PERIOD.  Officer acknowledges that the 
Corporation has advised Officer that he may consult with an attorney of his 
choosing prior to signing this Second Amendment and Release and that Officer 
has twenty-one (21) days during which to consider the provisions of this 
Second Amendment and Release, although Officer may sign and return it sooner. 
 Officer further acknowledges that he has been advised by the Corporation 
that he has the right to revoke this Second Amendment and Release for a 
period of seven (7) days after signing it and that this Second Amendment and 
Release shall not become effective or enforceable until such seven (7)-day 
revocation period has expired. Officer acknowledges and agrees that if he 
wishes to revoke this Agreement, he must do so in writing, and that such 
revocation must be signed by Officer and received by the Corporation no later 
than 5:00 p.m. Pacific Standard Time on the seventh (7th) day after Officer 
has signed this Second Amendment and Release.

Release acknowledges and represents that he or it (a) has fully and carefully 
read this Second Amendment and Release prior to signing it,(b) has been, or 
has had the opportunity to be, advised by independent legal counsel of his or 
its own choice as to the legal effect and meaning of each of the terms and 
conditions of this Second Amendment and Release, and (c) is signing and 
entering into this Second Amendment and Release freely and voluntarily and 
without duress or undue pressure or influence of any kind or nature 
whatsoever and has not relied on any promises, representations or warranties 
regarding the subject matter hereof other than that which is set forth in 
this Second Amendment and Release.

          6.   BINDING EFFECT.  This Second Amendment and Release shall be 
binding upon the Parties and their respective heirs, administrators, 
representatives, executors, successors and assigns, and shall inure to the 
benefit of the Parties and their respective heirs, administrators, 
representatives, executors, successors and assigns.

          7.   GOVERNING LAW.  This Second Amendment and Release shall be 
construed and enforced pursuant to the laws of the State of California 
applicable to contracts made and entirely to be performed therein.

          8.   COUNTERPARTS.  This Second Amendment and Release may be 
executed in counterparts, each of which shall be an original and all of which 
together shall constitute one and the same agreement.

          9.   ENTIRE AGREEMENT; MODIFICATION.  This Second Amendment and
Release, together with the Employment Agreement, constitute the entire
understanding of the Parties and neither the Second Amendment and Release, nor
the Employment Agreement, may be modified except in a writing signed by the
Parties.  Other than as set forth herein, this Second Amendment and Release
supersedes all prior written and/or oral and all contemporaneous oral
agreements, understandings and negotiations regarding the subject matter hereof.

                               REGISTRATION RIGHTS

          Section 2.1 DEMAND REGISTRATION.  (a)  REQUEST FOR REGISTRATION BY 
THE HOLDERS.  At any time and from time to time during the period commencing 
on the first anniversary of the Effective Date and ending on the second 
anniversary of the Effective Date, Holders owning, individually or in the 
aggregate, at least the Requisite Share Number may make a total of two 
written requests for a Demand Registration of not less than 10% of the 
Registrable Securities held by all Holders.  Such request will specify the 
number of Registrable Securities proposed to be sold and the intended method 
of disposition thereof.

          The Company shall give written notice of any registration request 
by the Holders, which request complies with this Section 2.1(a), within 10 
days after the receipt thereof, to each Holder who did not initially join in 
such request.  Within 20 days after receipt of such notice, any such Holder 
may request in writing that Registrable Securities owned by it be included in 
such registration.  Each such request shall specify the number of shares of 
Registrable Securities proposed to be sold and the intended method of 
disposition thereof.

          Subject to Section 2.3, the Company shall use its best efforts to 
effect the registration under the Securities Act of the Registrable 
Securities of each Holder that the Company has been so requested to register; 
PROVIDED, HOWEVER, that:  (i) the Company shall not be obligated to file or 
cause to become effective any registration statement during any period in 
which any other registration statement (other than a registration statement 
on Form S-4 or S-8 or any substitute form that may be adopted by the 
Commission) pursuant to which shares of Common Stock are to be or were sold 
has been filed and not withdrawn or has been declared effective within the 
prior 180 days; and (ii) the Company may delay the filing of a registration 
statement for a period of not more than 90 days after the date of 

                                        4
<PAGE>

receipt of a request in accordance with Section 2.1 if the Company reasonably 
determines that such a filing would adversely affect any proposed financing 
or acquisition by the Company and furnishes to the Demanding Holder a 
certificate signed by an executive officer of the Company to such effect.  If 
the Company delays the filing of a Registration Statement, it shall promptly 
notify the Demanding Holders in writing when the events or circumstances 
permitting such postponement have ended.

          (b)  EFFECTIVE REGISTRATION.  A registration will not be deemed to 
have been effected as a Demand Registration unless it has been declared 
effective by the Commission and the Company has complied in all material 
respects with its obligations under this Agreement with respect thereto; 
PROVIDED, that if, after it has become effective, the offering of Registrable 
Securities pursuant to such registration is or becomes the subject of any 
stop order, injunction or other order or requirement of the Commission or any 
other governmental or administrative agency, or if any court prevents or 
otherwise limits the sale of Registrable Securities pursuant to the 
registration (for any reason other than the acts or omissions of the 
Holders), such registration will be deemed not to have been effected.  If (i) 
a registration requested pursuant to this Section 2.1 is deemed not to have 
been effected or (ii) the registration requested pursuant to this Section 2.1 
is requested to be a "shelf" registration and it does not remain effective 
until the earlier to occur of 180 days after the effective date thereof or 
the consummation of the distribution by the Selling Holders of the 
Registrable Securities included in such registration statement, then such 
registration statement shall not count as a Demand Registration that may be 
requested by the Demanding Holder(s) in question and the Company shall 
continue to be obligated to effect a registration pursuant to this Section 
2.1.

          The Demanding Holders may withdraw all or any part of the Registrable
Securities from a Demand Registration at any time (whether before or after the
filing or effective date of such Demand Registration), and if all such
Registrable Securities are withdrawn, to withdraw the demand related thereto. 
If at any time a registration statement is filed pursuant to a Demand
Registration, and subsequently a sufficient number of Registrable Securities are
withdrawn from a Demand Registration so that such registration statement does
not cover at least the required amounts specified by Section 2.1(a), and an
additional number of Registrable Securities is not so included, the Company may
(or shall, if requested by the Demanding Holders) withdraw the registration
statement; and such registra-

                                        5
<PAGE>

tion statement will not count as a Demand Registration and the Company shall 
continue to be obligated to effect a registration pursuant to this Section 
2.1.

          (c) SELECTION OF UNDERWRITER.  If the Demanding Holders so elect, 
the  offering of Registrable Securities pursuant to a Demand Registration 
shall be in the form of an underwritten public offering.  The Demanding 
Holders shall select one or more nationally recognized firms of investment 
bankers to act as the bookrunning managing Underwriter or Underwriters in 
connection with such offering and shall select any additional investment 
bankers and managers to be used in connection with the offering; PROVIDED 
that such investment bankers and managers must be reasonably satisfactory to 
the Company.

          Section 2.2  PIGGY-BACK REGISTRATION.  If at any time the Company 
proposes to file a registration statement under the Securities Act with 
respect to an offering of equity securities by the Company for its own 
account or for the account of any securityholders of any class of its equity 
securities (other than (i) a registration statement on Form S-4 or S-8 (or 
any substitute form that may be adopted by the Commission) or (ii) a 
registration statement filed in connection with an exchange offer or offering 
of securities solely to the Company's existing securityholders), including a 
registration statement relating to a Demand Registration, then the Company 
shall give written notice of such proposed filing to the Holders as soon as 
practicable (but in no event less than 20 days before the anticipated filing 
date), and such notice shall offer such Holders the opportunity to register 
such number of shares of Registrable Securities as each such Holder may 
request (which request shall specify the Registrable Securities intended to 
be disposed of by such Holder and the intended method of distribution 
thereof) (a "Piggy-Back Registration").

          The Company shall use its best efforts to cause the managing 
Underwriter or Underwriters of a proposed underwritten public offering to 
permit the Registrable Securities requested by the Holders thereof to be 
included in a Piggy-Back Registration (the "Piggy-Back Holders") on the same 
terms and conditions as any similar securities of the Company or any other 
securityholder included therein and to permit the sale or other disposition 
of such Registrable Securities in accordance with the intended method of 
distribution thereof.  Any Holder shall have the right to withdraw its 
request for inclusion of its Registrable Securities in any registration 
statement pursuant to this Section 2.2 by giving written notice to the 
Company of its request to withdraw.  Subject to the provisions of Section 
2.1, the Company may withdraw a Piggy-Back Registration at any time 

                                        6
<PAGE>

prior to the time it becomes effective; PROVIDED that the Company shall 
reimburse the Piggy-Back Holders for all reasonable out-of-pocket expenses 
(including counsel fees and expenses) incurred prior to such withdrawal.

          No registration effected under this Section 2.2, and no failure to 
effect a registration under this Section 2.2, shall relieve the Company of 
its obligations pursuant to Section 2.1, and no failure to effect a 
registration under this Section 2.2 and to complete the sale of Shares in 
connection therewith shall relieve the Company of any other obligation under 
this Agreement (including, without limitation, the Company's obligations 
under Sections 3.2 and 4.1).

          Section 2.3  REDUCTION OF OFFERING.  (a) DEMAND REGISTRATION.  The 
Company may include in a Demand Registration shares of Common Stock for the 
account of the Company and Registrable Securities for the account of the 
Piggy-Back Holders and shares of Common Stock for the account of other 
holders thereof exercising contractual piggy-back rights, on the same terms 
and conditions as the Registrable Securities to be included therein for the 
account of the Demanding Holders; PROVIDED, HOWEVER, that (i) if the managing 
Underwriter or Underwriters of any underwritten public offering described in 
Section 2.1 have informed the Company in writing that it is their opinion 
that the total number of shares which the Demanding Holders, the Company, any 
Piggy-Back Holders and any such other holders intend to include in such 
offering is such as to materially and adversely affect the success of such 
offering, then (x) the number of shares to be offered for the account of the 
Company (if any) shall be reduced (to zero, if necessary) and (y) thereafter, 
if necessary, the number of shares to be offered for the account of such 
Piggy-Back Holders and such other holders shall be reduced (to zero, if 
necessary), in the case of this clause (y) PRO RATA in proportion to the 
respective number of shares requested to be registered to the extent 
necessary to reduce the total number of shares requested to be included in 
such offering to the number of shares, if any, recommended by such managing 
Underwriters; and if the number of shares to be offered for the account of 
each such Person has been reduced to zero, and the number of Shares requested 
to be registered by the Demanding Holders exceeds the number of shares 
recommended by such managing Underwriters, then the number of Shares to be 
offered for the account of the Demanding Holders shall be reduced PRO RATA in 
proportion to the respective number of Shares requested to be registered by 
the Demanding Holders and (ii) if the offering is not underwritten, no other 
party (other than Piggy-Back Holders), including the Company, shall be 
permitted to offer securities under any such 

                                        7
<PAGE>

Demand Registration unless a majority of the Shares held by the Demanding 
Holder or Holders consent to the inclusion of such shares therein.

          (b) PIGGY-BACK REGISTRATION.  Notwithstanding anything contained 
herein, if the managing Underwriter or Underwriters of any public offering 
described in Section 2.2 have informed, in writing, the Piggy-Back Holders 
that it is their opinion that the total number of shares that the Company and 
Holders of Registrable Securities and any other Persons desiring to 
participate in such registration intend to include in such offering is such 
as to materially and adversely affect the success of such offering, then the 
number of shares to be offered for the account of the Piggy-Back Holders and 
all such other Persons (other than the Company) participating in such 
registration shall be reduced (to zero, if necessary) or limited PRO RATA in 
proportion to the respective number of shares requested to be registered to 
the extent necessary to reduce the total number of shares requested to be 
included in such offering to the number of shares, if any, recommended by 
such managing Underwriters; PROVIDED, HOWEVER, that (i) if such offering is 
effected for the account of Demanding Holders pursuant to Section 2.1, then 
the number of shares to be offered for the account of each Person shall be 
reduced in accordance with Section 2.3(a), and (ii) if such offering is 
effected for the account of any other securityholder of the Company pursuant 
to the demand registration rights of such securityholder, then the number of 
shares to be offered for the account of each Person shall be reduced in 
accordance with the instrument granting such demand registration rights, if 
any, and, in the absence of such instrument (x) the number of shares to be 
offered for the account of the Company, if any, shall be reduced (to zero, if 
necessary) and (y) thereafter, if necessary, the number of shares to be 
offered for the account of the Piggy-Back Holders and any other Persons that 
have requested to include shares in such registration (but not such 
securityholders who have exercised their demand registration rights) shall be 
reduced (to zero, if necessary), in the case of this clause (y) PRO RATA in 
proportion to the respective number of shares requested to be registered, to 
the extent necessary to reduce the total number of shares requested to be 
included in such offering to the number of shares, if any, recommended by 
such managing Underwriters.

          Section 3.1  FILINGS: INFORMATION.  Whenever the Company is 
required to effect or cause the registration of Registrable Securities 
pursuant to Section 2.1, the Company will use its best efforts to effect the 
registration and the sale of such Registrable Securities in accordance with 
the intended method of disposition thereof as quickly as practicable, and in 
connection with any such request:

          (a)  The Company will as expeditiously as possible prepare and file 
with the Commission a registration statement on any form for which the 
Company then qualifies or which counsel for the Company shall deem 
appropriate and which form shall be available for the sale of the Registrable 
Securities to be registered thereunder in accordance with the intended method 
of distribution thereof, and use its best efforts to cause such filed 
registration statement to become and remain effective as provided herein.

          (b)  The Company will as expeditiously as possible prepare and file 
with the Commission such amendments and supplements to such registration 
statement and the prospectus used in connection therewith as may be necessary 
to keep such registration statement continuously effective (subject to the 
penultimate paragraph of this Section 3.1) during the period with respect to 
the disposition of all securities covered by such registration statement as 
provided herein (but not before the expiration of the 90-day period referred 
to in Section 4(3) of the Securities Act and Rule 174 thereunder, if 
applicable) and comply with the provisions of the Securities Act with respect 
to the disposition of all securities covered by such registration statement 
during such period in accordance with the intended methods of disposition by 
each Selling Holder thereof set forth in such registration statement.

          (c)  The Company will, prior to filing a registration statement or 
prospectus or any amendment or supplement thereto, furnish to each Selling 
Holder, counsel representing such Selling Holders, and each Underwriter, if 
any, of the Registrable Securities covered by such registration statement 
copies of such registration statement as proposed to be filed, together with 
exhibits thereto if so requested, which documents will be subject to review 
and comment by the foregoing within five days after delivery, and thereafter 
furnish to such Selling Holder, counsel and Underwriter, if any, for their 
review and comment such number of copies of such registration statement, each 
amendment and supplement thereto (in each case including all exhibits thereto 
if so requested), the prospectus included in such registration statement 
(including each preliminary prospectus) and such other 

                                        9
<PAGE>

documents or information as such Selling Holder, counsel or Underwriter may 
reasonably request in order to facilitate the disposition of the Registrable 
Securities owned by such Selling Holder.

          (d)  After the filing of the registration statement, the Company 
will promptly notify each Selling Holder of Registrable Securities covered by 
such registration statement (i) when a prospectus or any prospectus 
supplement or post-effective amendment has been filed and, with respect to a 
registration statement or any post-effective amendment, when the same has 
become effective, (ii) of any request by the Commission or any other federal 
or state governmental authority for amendments or supplements to a 
registration statement or related prospectus or for additional information, 
(iii) of the issuance by the Commission or any other federal or state 
governmental authority of any stop order suspending the effectiveness of a 
registration statement or the initiation of any proceedings for that purpose, 
(iv) of the receipt by the Company of any notification with respect to the 
suspension of the qualification or exemption from qualification of any of the 
Registrable Securities for sale in any jurisdiction or the initiation or 
threatening of any proceeding for such purpose, (v) of the happening of any 
event that makes any statement made in such registration statement or related 
prospectus or any document incorporated or deemed to be incorporated therein 
by reference untrue in any material respect or that requires the making of 
any changes in a registration statement, prospectus or documents incorporated 
therein by reference so that, in the case of the registration statement, it 
will not contain any untrue statement of a material fact or omit to state any 
material fact required to be stated therein or necessary to make the 
statements therein not misleading, and that in the case of the prospectus, it 
will not contain any untrue statement of a material fact or omit to state any 
material fact required to be stated therein or necessary to make the 
statements therein, in light of the circumstances under which they were made, 
not misleading, and (vi) of the Company's reasonable determination that a 
post-effective amendment to a registration statement would be necessary.

          (e)  The Company will use its best efforts to (i) register or 
qualify the Registrable Securities under such other securities or blue sky 
laws of such jurisdictions in the United States as any Selling Holder 
reasonably (in light of such Selling Holder's intended plan of distribution) 
requests, and (ii) cause such Registrable Securities to be registered with or 
approved by such other govern-mental agencies or authorities in the United 
States as may be necessary by virtue of the business and operations of the 
Company and do any and all other acts and things that may be reasonably 
necessary or advisable to enable such Selling Holder 

                                        11
<PAGE>

to consummate the disposition of the Registrable Securities owned by such 
Selling Holder; PROVIDED that the Company will not be required to (A) qualify 
generally to do business in any jurisdiction where it would not otherwise be 
required to qualify but for this paragraph (e), (B) subject itself to 
taxation in any such jurisdiction or (C) consent to general service of 
process in any such jurisdiction.

          (f)  The Company will take all reasonable actions required to 
prevent the entry, or obtain the withdrawal, of any order suspending the 
effectiveness of a registration statement, or the lifting of any suspension 
of the qualification (or exemption from qualification) of any Registrable 
Securities for sale in any jurisdiction, at the earliest moment.

          (g)  Upon the occurrence of any event contemplated by paragraph 
3.1(d)(v) or 3.1(d)(vi) above, the Company will (i) prepare a supplement or 
post-effective amendment to such registration statement or a supplement to 
the related prospectus or any document incorporated therein by reference or 
file any other required document so that, as thereafter delivered to the 
purchasers of the Registrable Securities being sold thereunder, such 
prospectus will not contain an untrue statement of a material fact or omit to 
state a material fact required to be stated therein or necessary to make the 
statements therein, in light of the circumstances under which they were made, 
not misleading, and (ii) promptly make available to each Selling Holder any 
such supplement or amendment.

          (h)  The Company will enter into customary agreements (including, 
if applicable, an underwriting agreement in customary form and reasonably 
satisfactory to the Company) and take such other actions as are reasonably 
required in order to expedite or facilitate the disposition of such 
Registrable Securities (the Selling Holders may, at their option, require 
that any or all of the representations, warranties and covenants of the 
Company to or for the benefit of such Underwriters also be made to and for 
the benefit of such Selling Holders).

          (i)  The Company will make available to each Selling Holder (and 
their counsel) and each Underwriter, if any, subject to restrictions imposed 
by the United States federal government or any agency or instrumentality 
thereof, copies of all correspondence between the Commission and the Company, 
its counsel or auditors and will also make available for inspection by any 
Selling Holder, any Underwriter participating in any disposition pursuant to 
such registration statement and any attorney, accountant or other 
professional retained by any such Selling Holder or Underwriter 
(collectively, the "Inspectors"), all financial and other 

                                        11
<PAGE>

records, pertinent corporate documents and properties of the Company 
(collectively, the "Records") as shall be reasonably necessary to enable them 
to exercise their due diligence responsibility, and cause the Company's 
officers and employees to supply all information reasonably requested by any 
Inspectors in connection with such registration statement.  Records that the 
Company determines, in good faith, are confidential, and of which 
determination the Company so notifies the Inspectors, shall not be disclosed 
by the Inspectors unless (i) the disclosure of such Records is necessary to 
avoid or correct a misstatement or omission in such registration statement or 
(ii) the disclosure or release of such Records is requested or required 
pursuant to oral questions, interrogatories, requests for information or 
documents or a subpoena or other order from a court of competent jurisdiction 
or other process; PROVIDED that prior to any disclosure or release pursuant 
to clause (ii), the Inspectors shall provide the Company with prompt notice 
of any such request or requirement so that the Company may seek an 
appropriate protective order or waive such Inspectors' obligation not to 
disclose such Records; and, PROVIDED FURTHER, that if, failing the entry of a 
protective order or the waiver by the Company permitting the disclosure or 
release of such Records, the Inspectors, upon advice of counsel, are 
compelled to disclose such Records, the Inspectors may disclose only that 
portion of the Records that counsel has advised them that they are compelled 
to disclose. Each Selling Holder agrees that information obtained by it 
solely as a result of such inspections shall be deemed confidential and shall 
not be used by it as the basis for any market transactions in the securities 
of the Company or its Affiliates unless and until such information is made 
generally available to the public.  

          (j)  The Company will furnish to each Selling Holder and to each 
Underwriter, if any, a signed counterpart, addressed to such Selling Holder 
or Underwriter, of (i) an opinion or opinions of counsel to the Company, and 
(ii) a comfort letter or comfort letters from the Company's independent 
public accountants, each in customary form and covering such matters of the 
type customarily covered by opinions or comfort letters, as the case may be, 
as the Selling Holders or the managing Underwriter therefor reasonably 
requests.

          (k)  The Company will otherwise use its best efforts to comply with 
all applicable rules and regulations of the Commission, and make available to 
its securityholders, as soon as reasonably practicable, an earnings statement 
covering a period of 12 months, beginning within three months after the 
effective date of the registration statement, which earnings statement shall 
satisfy the provisions of Section 11(a) of the Securities Act.

                                        12

<PAGE>

          (l)  The Company will use its best efforts (i) to cause any class 
of Registrable Securities to be listed on a national securities exchange (if 
such shares are not already so listed) and on each additional national 
securities exchange on which similar securities issued by the Company are 
then listed (if any), if the listing of such Registrable Securities is then 
permitted under the rules of such exchange or (ii) to secure designation of 
all such Registrable Securities covered by such registration statement as a 
NASDAQ "national market system security" within the meaning of Rule 11Aa2-1 
of the Commission or, failing that, to secure NASDAQ authorization for such 
Registrable Securities.

          (m)  In connection with an underwritten public offering, the 
Company will participate, to the extent reasonably requested by the managing 
Underwriter for the offering or the Selling Holders, in customary efforts to 
sell the securities under the offering, including, without limitation, 
participating in "road shows"; PROVIDED that the Company shall not be 
obligated so to participate in more than one such offering in any 12-month 
period.

          The Company may require each Selling Holder to promptly furnish in 
writing to the Company such information regarding the distribution of the 
Registrable Securities by such Selling Holder as the Company may from time to 
time reasonably request and such other information as may be legally required 
in connection with such registration including, without limitation, all such 
information as may be requested by the Commission or the NASD.  The Company 
may exclude from such registration any Holder who fails to provide such 
information.

          Each Selling Holder agrees that, upon receipt of any notice from 
the Company of the happening of any event of the kind described in Sections 
3.1(d)(iii), (iv), (v) and (vi) hereof, such Selling Holder will forthwith 
discontinue disposition of Registrable Securities pursuant to the 
registration statement covering such Registrable Securities until such 
Selling Holder's receipt of the copies of the supplemented or amended 
prospectus contemplated by Section 3.1(g) hereof, and, if so directed by the 
Company, such Selling Holder will deliver to the Company all copies, other 
than permanent file copies, then in such Selling Holder's possession of the 
most recent prospectus covering such Registrable Securities at the time of 
receipt of such notice.  In the event the Company shall give such notice, the 
Company shall extend the period during which such registration statement 
shall be maintained effective as provided herein by the number of days during 
the period from and including the date of the giving of notice pursuant to 
Section 3.1(d)(iii), (iv), (v) or (vi) hereof to the date when the Company 
shall make available to the 

                                        13
<PAGE>

Selling Holders a prospectus supplemented or amended to conform with the 
requirements of Section 3.1(g) hereof.

          In connection with any registration of Registrable Securities 
pursuant to Section 2.2, the Company will take the actions contemplated by 
paragraphs (c), (d), (e), (g), (i), (j), (k) and (l) above.

          Section 3.2 REGISTRATION EXPENSES.  In connection with a Demand 
Registration pursuant to Section 2.1 hereof, and any registration statement 
filed pursuant to Section 2.2 hereof, the Company shall pay the following 
registration expenses incurred in connection with the registration hereunder 
(i) all registration and filing fees, (ii) fees and expenses of compliance 
with securities or blue sky laws (including reasonable fees and disbursements 
of counsel in connection with blue sky qualifications of the Registrable 
Securities), (iii) printing expenses, (iv) the Company's internal expenses 
(including, without limitation, all salaries and expenses of its officers and 
employees performing legal or accounting duties) and all fees and expenses 
incident to the performance of or compliance with this Agreement by the 
Company, (v) the fees and expenses incurred in connection with the listing of 
the Registrable Securities, (vi) reasonable fees and disbursements of counsel 
for the Company and customary fees and expenses for independent certified 
public accountants retained by the Company (including the expenses of any 
comfort letters or costs associated with the delivery by independent 
certified public accountants of a comfort letter or comfort letters requested 
pursuant to Section 3.1(j) hereof), (vii) the reasonable fees and expenses of 
any special experts retained by the Company in connection with such 
registration, and (viii) reasonable fees and expenses of one firm of counsel 
for the Holders (together with necessary local counsel fees and expenses), 
which counsel shall be chosen by the Demanding Holders or, if none, by the 
Holders of a majority of the Registrable Securities being included in such 
Registration Statement.  The Company shall have no obligation to pay any 
underwriting fees, discounts or commissions attributable to the sale of 
Registrable Securities.

                         INDEMNIFICATION AND CONTRIBUTION

          Section 4.1  INDEMNIFICATION BY THE COMPANY.  The Company agrees to 
indemnify and hold harmless each Selling Holder, its partners, officers, 
direc-

                                        14

tors, employees, agents, and Controlling Persons from and against any and all 
Damages, joint or several, and any action in respect thereof to which such 
Selling Holder, its partners, officers, directors, employees and agents, and 
any such Controlling Person may become subject under the Securities Act or 
otherwise, insofar as such Damages (or proceedings in respect thereof) arise 
out of, or are based upon, any untrue statement or alleged untrue statement 
of a material fact contained in any registration statement or prospectus 
relating to the Registrable Securities or any preliminary prospectus, or 
arises out of, or are based upon, any omission or alleged omission to state 
therein a material fact required to be stated therein or necessary to make 
the statements therein not misleading, except insofar as the same are based 
upon information furnished to the Company by a Selling Holder or Underwriter 
expressly for use therein, and shall reimburse each Selling Holder, its 
partners, officers, directors, employees and agents, and each such 
Controlling Person for any legal and other expenses reasonably incurred by 
that Selling Holder, its partners, officers, directors, employees and agents, 
or any such Controlling Person in investigating or defending or preparing to 
defend against any such Damages or proceedings; PROVIDED, that the Company 
shall not be liable to any Selling Holder to the extent that (a) any such 
Damages arise out of or are based upon an untrue statement or omission made 
in any preliminary prospectus if (i) such Selling Holder failed to send or 
deliver a copy of the final prospectus with or prior to the delivery of 
written confirmation of the sale by such Selling Holder to the Person 
asserting the claim from which such Damages arise, and (ii) the final 
prospectus would have corrected such untrue statement or such omission; or 
(b) any such Damages arise out of or are based upon an untrue statement or 
omission in any prospectus if (x) such untrue statement or omission is 
corrected in an amendment or supplement to such prospectus, and (y) having 
previously been furnished by or on behalf of the Company with copies of such 
prospectus as so amended or supplemented, such Selling Holder thereafter 
fails to deliver such prospectus as so amended or supplemented prior to or 
concurrently with the sale of a Registrable Security to the Person asserting 
the claim from which such Damages arise.

          Section 4.2  INDEMNIFICATION BY HOLDERS OF REGISTRABLE SECURITIES. 
Each Selling Holder agrees, severally but not jointly, to indemnify and hold 
harmless the Company, its officers, directors, employees and agents and each 
Person, if any, who controls the Company within the meaning of Section 15 of 
the Securities Act or Section 20 of the Exchange Act, together with the 
partners, officers, directors, employees and agents of such controlling 
Person, to the same extent as the foregoing indemnity from the Company to 
such Selling Holder, but 

                                        15
<PAGE>

only with reference to information related to such Selling Holder or its plan 
of distribution, as furnished by such Selling Holder or on such Selling 
Holder's behalf expressly for use in any registration statement or prospectus 
relating to the Registrable Securities, or any amendment or supplement 
thereto, or any preliminary prospectus.  In case any action or proceeding 
shall be brought against the Company or its officers, directors, employees or 
agents or any such controlling Person or its partners, officers, directors, 
employees or agents, in respect of which indemnity may be sought against such 
Selling Holder, such Selling Holder shall have the rights and duties given to 
the Company, and the Company or its officers, directors, employees or agents, 
controlling Person, or its partners, officers, directors, employees or 
agents, shall have the rights and duties given to such Selling Holder, under 
Section 4.1.  Each Selling Holder also agrees to indemnify and hold harmless 
each other Selling Holder and any Underwriters of the Registrable Securities, 
and their respective officers and directors and each Person who controls each 
such other Selling Holder or Underwriter on substantially the same basis as 
that of the indemnification of the Company provided in this Section 4.2.  The 
Company shall be entitled to receive indemnities from Underwriters, selling 
brokers, dealer managers and similar securities industry professionals 
participating in the distribution, to the same extent as provided above, with 
respect to information so furnished by such Persons specifically for 
inclusion in any prospectus or registration statement.  In no event shall the 
liability of any Selling Holder be greater in amount than the dollar amount 
of the proceeds (net of payment of all expenses) received by such Selling 
Holder upon the sale of the Registrable Securities giving rise to such 
indemnification obligation.

          Section 4.3  CONDUCT OF INDEMNIFICATION PROCEEDINGS.  Promptly 
after receipt by any Person in respect of which indemnity may be sought 
pursuant to Section 4.1 or 4.2 (an "Indemnified Party") of notice of any 
claim or the commencement of any action, the Indemnified Party shall, if a 
claim in respect thereof is to be made against the Person against whom such 
indemnity may be sought (an "Indemnifying Party"), notify the Indemnifying 
Party in writing of the claim or the commencement of such action, PROVIDED 
that the failure to notify the Indemnifying Party shall not relieve the 
Indemnifying Party from any liability except to the extent of any material 
prejudice resulting therefrom.  If any such claim or action shall be brought 
against an Indemnified Party, and it shall notify the Indemnifying Party 
thereof, the Indemnifying Party shall be entitled to participate therein, 
and, to the extent that it wishes, jointly with any other similarly notified 
Indemnifying Party, to assume the defense thereof with counsel reasonably 
satisfactory to the Indemnified Party.  After notice from the Indemnifying 
Party to 

                                        16
<PAGE>

the Indemnified Party of its election to assume the defense of such claim or 
action, the Indemnifying Party shall not be liable to the Indemnified Party 
for any legal or other expenses subsequently incurred by the Indemnified 
Party in connection with the defense thereof other than reasonable costs of 
investigation; PROVIDED that the Indemnified Party shall have the right to 
employ separate counsel to represent the Indemnified Party and its 
controlling Persons who may be subject to liability arising out of any claim 
in respect of which indemnity may be sought by the Indemnified Party against 
the Indemnifying Party, but the fees and expenses of such counsel shall be 
for the account of such Indemnified Party unless (i) the Indemnifying Party 
and the Indemnified Party shall have mutually agreed to the retention of such 
counsel or (ii) in the reasonable judgment of the Indemnifying Party and such 
Indemnified Party, representation of both parties by the same counsel would 
be inappropriate due to actual or potential conflicts of interest between 
them, it being understood however, that the Indemnifying Party shall not, in 
connection with any one such claim or action or separate but substantially 
similar or related claims or actions in the same jurisdiction arising out of 
the same general allegations or circumstances, be liable for the fees and 
expenses of more than one separate firm of attorneys (together with 
appropriate local counsel) at any time for all Indemnified Parties, or for 
fees and expenses that are not reasonable.  No Indemnifying Party shall, 
without the prior written consent of the Indemnified Party, effect any 
settlement of any claim or pending or threatened proceeding in respect of 
which the Indemnified Party is or could have been a party and indemnity could 
have been sought hereunder by such Indemnified Party, unless such settlement 
includes an unconditional release of such Indemnified Party from all 
liability arising out of such claim or proceeding.  Whether or not the 
defense of any claim or action is assumed by the Indemnifying Party, such 
Indemnifying Party will not be subject to any liability for any settlement 
made without its consent, which consent will not be unreasonably withheld.

          Section 4.4  CONTRIBUTION.  If the indemnification provided for in 
this Article IV is unavailable to the Indemnified Parties in respect of any 
Damages referred to herein, then each Indemnifying Party, in lieu of 
indemnifying such Indemnified Party, shall contribute to the amount paid or 
payable by such Indemnified Party as a result of such Damages (i) as between 
the Company and the Selling Holders on the one hand and the Underwriters on 
the other, in such proportion as is appropriate to reflect the relative benefits
received by the Company and the Selling Holders on the one hand and the 
Underwriters on the other from the offering of the Registrable Securities, or if
such allocation is not permitted by applicable law, in such proportion as is 
appropriate to reflect not only the relative 

                                        17
<PAGE>

benefits but also the relative fault of the Company and the Selling Holders 
on the one hand and of the Underwriters on the other in connection with the 
statements or omissions which resulted in such Damages, as well as any other 
relevant equitable considerations, and (ii) as between the Company on the one 
hand and each Selling Holder on the other, in such proportion as is 
appropriate to reflect the relative fault of the Company and of each Selling 
Holder in connection with such statements or omissions, as well as any other 
relevant equitable considerations.  The relative benefits received by the 
Company and the Selling Holders on the one hand and the Underwriters on the 
other shall be deemed to be in the same proportion as the total proceeds from 
the offering (net of underwriting discounts and commissions but before 
deducting expenses) received by the Company and the Selling Holders bear to 
the total underwriting discounts and commissions received by the 
Underwriters, in each case as set forth in the table on the cover page of the 
prospectus.  The relative fault of the Company and the Selling Holders on the 
one hand and of the Underwriters on the other shall be determined by 
reference to, among other things, whether the untrue or alleged untrue 
statement of a material fact or the omission or alleged omission to state a 
material fact relates to information supplied by the Company and the Selling 
Holders or by the Underwriters.  The relative fault of the Company on the one 
hand and of each Selling Holder on the other shall be determined by reference 
to, among other things, whether the untrue or alleged untrue statement of a 
material fact or the omission or alleged omission to state a material fact 
relates to information supplied by such party, and the parties' relative 
intent, knowledge, access to information and opportunity to correct or 
prevent such statement or omission.

          The Company and the Selling Holders agree that it would not be just 
and equitable if contribution pursuant to this Section 4.4 were determined by 
pro rata allocation (even if the Underwriters were treated as one entity for 
such purpose) or by any other method of allocation which does not take 
account of the equitable considerations referred to in the immediately 
preceding paragraph.  The amount paid or payable by an Indemnified Party as a 
result of the Damages referred to in the immediately preceding paragraph 
shall be deemed to include, subject to the limitations set forth above, any 
legal or other expenses reasonably incurred by such Indemnified Party in 
connection with investigating or defending any such action or claim.  
Notwithstanding the provisions of this Section 4.4, no Underwriter shall be 
required to contribute any amount in excess of the amount by which the total 
price at which the Registrable Securities underwritten by it and distributed 
to the public were offered to the public exceeds the amount of any damages 
which such Underwriter has otherwise been required to pay by reason of 

                                        18

<PAGE>

such untrue or alleged untrue statement or omission or alleged omission, and 
no Selling Holder shall be required to contribute any amount in excess of the 
amount by which the total price at which the Registrable Securities of such 
Selling Holder were offered to the public (less underwriting discounts and 
commissions) exceeds the amount of any damages which such Selling Holder has 
otherwise been required to pay by reason of such untrue or alleged untrue 
statement or omission or alleged omission.  No Person guilty of fraudulent 
misrepresentation (within the meaning of Section 11(f) of the Securities Act) 
shall be entitled to contribution from any Person who was not guilty of such 
fraudulent misrepresentation.  Each Selling Holder's obligation to contribute 
pursuant to this Section 4.4 is several and not joint.

          The indemnity, contribution and expense reimbursement obligations 
contained in this Article IV are in addition to any liability any 
Indemnifying Party may otherwise have to an Indemnified Party or otherwise.  
The provisions of this Article IV shall survive, notwithstanding any transfer 
of the Registrable Securities by any Holder or any termination of this 
Agreement.
                                        
                                    ARTICLE V

                                  MISCELLANEOUS

          Section 5.1  PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.  No 
Person may participate in any underwritten registration hereunder unless such 
Person (a) agrees to sell such Person's securities on the basis provided in 
any underwriting arrangements approved by the Persons entitled hereunder to 
approve such arrangements, and (b) completes and executes all questionnaires, 
indemnities, underwriting agreements and other documents reasonably required 
under the terms of such underwriting arrangements and these registration 
rights; PROVIDED, that (i) no Selling Holder shall be required to make any 
representations or warranties except those which relate solely to such Holder 
and its intended method of distribution, and (ii) the liability of each such 
Holder to any Underwriter under such underwriting agreement will be limited 
to liability arising from misstatements or omissions regarding such Holder 
and its intended method of distribution and any such liability shall not

Subsidiaries and Affiliates, in the discretion of the Committee; PROVIDED 
THAT ISOs may be granted only to employees of the Company or of a Subsidiary. 
 In determining the persons to whom Awards and Loans shall be granted and the 
type (including the number of shares to be covered) of any Award or the 
amount of any Loan, the Committee shall take into account such factors as the 
Committee shall deem relevant in connection with accomplishing the purposes 
of the Plan.

          5.   STOCK SUBJECT TO THE PLAN.

          The maximum number of shares of Stock reserved for the grant of 
Awards under the Plan shall be 900,000, subject to adjustment as provided 
herein.  No more than 100% of the total shares available for grant may be 
awarded to a single individual in a single year.  Such shares may, in whole 
or in part, be authorized but unissued shares or shares that shall have been 
or may be reacquired by the Company in the open market, in private 
transactions or otherwise.  If any shares subject to an Award are forfeited, 
cancelled, exchanged or surrendered, or if an Award otherwise terminates or 
expires without a distribution of shares to the Grantee, the shares of stock 
with respect to such Award shall, to the extent of any such forfeiture, 
cancellation, exchange, surrender, termination or expiration, again be 
available for Awards under the Plan; PROVIDED THAT, in the case of 
forfeiture, cancellation, exchange or surrender of shares of Restricted Stock 
with respect to which dividends have been paid or accrued, the number of 
shares with respect to such Awards shall not be available for Awards 
hereunder unless, in the case of shares with respect to which dividends were 
accrued but unpaid, such dividends are also forfeited, cancelled, exchanged 
or surrendered.  Upon the exercise of any Award granted in tandem with any 
other Awards or awards, such related Awards or awards shall be cancelled to 
the extent of the number of shares of Stock as to which the Award is 
exercised and, notwithstanding the foregoing, such number of shares shall no 
longer be available for Awards under the Plan.

          In the event that the Committee shall determine that any dividend 
or other distribution (whether in the form of cash, Stock, or other 
property), recapitalization, stock split, reverse split, reorganization, 
merger, consolidation, spin-off, combination, repurchase, or share exchange, 
or other similar corporate transaction or event, affects the Stock such that 
an adjustment is appropriate in order to prevent dilution or enlargement of 
the rights of Grantees under the Plan, 

                                        8
<PAGE>

then the Committee shall make such equitable changes or adjustments as it 
deems necessary or appropriate to any or all of (a) the number and kind of 
shares of Stock which may thereafter be issued in connection with Awards, (b) 
the number and kind of shares of Stock issued or issuable in respect of 
outstanding Awards, and (c) the exercise price, grant price, or purchase 
price relating to any Award; PROVIDED THAT, with respect to ISOs, such 
adjustment shall be made in accordance with Section 424(h) of the Code. 

          6.   SPECIFIC TERMS OF AWARDS.

               6.1  GENERAL.  The term of each Award shall be for such period 
as may be determined by the Committee.  Subject to the terms of the Plan and 
any applicable Award Agreement, payments to be made by the Company or a 
Subsidiary or Affiliate upon the grant, maturation, or exercise of an Award 
may be made in such forms as the Committee shall determine at the date of 
grant or thereafter, including, without limitation, cash, Stock, or other 
property, and may be made in a single payment or transfer, in installments, 
or on a deferred basis.  The Committee may make rules relating to installment 
or deferred payments with respect to Awards, including the rate of interest 
to be credited with respect to such payments.  In addition to the foregoing, 
the Committee may impose on any Award or the exercise thereof, at the date of 
grant or thereafter, such additional terms and conditions, not inconsistent 
with the provisions of the Plan, as the Committee shall determine .

               6.2  OPTIONS.  The Committee is authorized to grant Options to 
Grantees on the following terms and conditions:

                    (a) TYPE OF AWARD.  The Award Agreement evidencing the 
grant of an Option under the Plan shall designate the Option as an ISO or an 
NQSO.

                    (b) EXERCISE PRICE.  The exercise price per share of 
Stock purchasable under an Option shall be determined by the Committee; 
PROVIDED THAT, in the case of an ISO, such exercise price shall be not less 
than the Fair Market Value of a share on the date of grant of such Option, 
and in no event shall the exercise price for the purchase of shares be less 
than par value.  The exercise price for Stock subject to an Option may be 
paid in cash or subject to the approval of the Committee, by an exchange of 
Stock previously owned by the Grantee, or a combination of both, in an amount 
having a combined value equal to such exercise 

                                        9
<PAGE>

price.  Subject to the approval of the Committee, a Grantee may pay all or a 
portion of the aggregate exercise price by having shares of Stock with a Fair 
Market Value on the date of exercise equal to the aggregate exercise price 
withheld by the Company or sold by a broker-dealer under circumstances 
meeting the requirements of 12 C.F.R. Section  220 or any successor thereof.

                    (c) TERM AND EXERCISABILITY OF OPTIONS.  The date on 
which the Committee adopts a resolution expressly granting an Option shall be 
considered the day on which such Option is granted.  Options shall be 
exercisable over the exercise period (which shall not exceed ten years from 
the date of grant), at such times and upon such conditions as the Committee 
may determine, as reflected in the Award Agreement; PROVIDED THAT, the 
Committee shall have the authority to accelerate the exercisability of any 
outstanding Option at such time and under such circumstances as it, in its 
sole discretion, deems appropriate.  An Option may be exercised to the extent 
of any or all full shares of Stock as to which the Option has become 
exercisable, by giving written notice of such exercise to the Committee or 
its designated agent.

                    (d) TERMINATION OF EMPLOYMENT, ETC.  An Option may not be 
exercised unless the Grantee is then in the employ of, or then maintains an 
independent contractor relationship with, the Company or a Subsidiary or an 
Affiliate (or a company or a parent or Subsidiary company of such company 
issuing or assuming the Option in a transaction to which Section 424(a) of 
the Code applies); PROVIDED THAT ISOs may be granted only to employees of the 
Company or of a Subsidiary, and may not be exercised unless the Grantee has 
remained continuously so employed, or has continuously maintained such 
relationship, since the date of grant of the Option; PROVIDED THAT, the Award 
Agreement may contain provisions extending the exercisability of Options, in 
the event of specified terminations, to a date not later than the expiration 
date of such Option.

                    (e) OTHER PROVISIONS.  Options may be subject to such 
other conditions including, but not limited to, restrictions on 
transferability of the shares acquired upon exercise of such Options, as the 
Committee may prescribe in its discretion or as may be required by applicable 
law, including but not limited to the requirements respecting ISOs set forth 
in Section 422 of the Code.

               6.3  SARs.  The Committee is authorized to grant SARs to 
Grantees on the following terms and conditions:

                                        10
<PAGE>

                    (a) IN GENERAL.  Unless the Committee determines 
otherwise, (i) an SAR granted in tandem with an NQSO may be granted at the 
time of grant of the related NQSO or at any time thereafter or (ii) an SAR 
granted in tandem with an ISO may only be granted at the time of grant of the 
related ISO.  An SAR granted in tandem with an Option shall be exercisable 
only to the extent the underlying Option is exercisable.

                    (b) SARs.  An SAR shall confer on the Grantee a right to 
receive an amount with respect to each share subject thereto, upon exercise 
thereof, equal to the excess of (i) the Fair Market Value of one share of 
Stock on the date of exercise over (ii) the grant price of the SAR (which in 
the case of an SAR granted in tandem with an Option shall be equal to the 
exercise price of one share of Stock underlying the Option, and which in the 
case of any other SAR shall be such price as the Committee may determine).

               6.4  RESTRICTED STOCK.  The Committee is authorized to grant 
Restricted Stock to Grantees on the following terms and conditions:

                    (a) ISSUANCE AND RESTRICTIONS.  Restricted Stock shall be 
subject to such restrictions on transferability and other restrictions, if 
any, as the Committee may impose at the date of grant or thereafter, which 
restrictions may lapse separately or in combination at such times, under such 
circumstances, in such installments, or otherwise, as the Committee may 
determine.  Such restrictions may include factors relating to the increase in 
the value of the Stock or to individual or Company performance such as the 
attainment of certain specified individual or Company-wide performance goals 
or earnings per share.  Except to the extent restricted under the Award 
Agreement relating to the Restricted Stock, a Grantee granted Restricted 
Stock shall have all of the rights of a stockholder including, without 
limitation, the right to vote Restricted Stock and the right to receive 
dividends thereon.

                    (b) FORFEITURE.  Upon termination of employment with or 
service to the Company and any Subsidiary, or upon termination of the 
independent contractor relationship, as the case may be, during the 
applicable restriction period, Restricted Stock and any accrued but unpaid 
dividends that are at that time subject to restrictions shall be forfeited; 
PROVIDED THAT, the Committee may provide, by rule or regulation or in any 
Award Agreement, or may determine in any individual case, that restrictions 
or forfeiture conditions relating to Restricted Stock will be waived in whole 
or in part in the event of terminations 

                                        11

<PAGE>

resulting from specified causes, and the Committee may in other cases waive 
in whole or in part the forfeiture of Restricted Stock.

                    (c) CERTIFICATES FOR STOCK.  Restricted Stock granted 
under the Plan may be evidenced in such manner as the Committee shall 
determine.  If certificates representing Restricted Stock are registered in 
the name of the Grantee, such certificates shall bear an appropriate legend 
referring to the terms, conditions, and restrictions applicable to such 
Restricted Stock, and the Company shall retain physical possession of the 
certificate.

                    (d) DIVIDENDS.  Dividends paid on Restricted Stock shall 
either be paid at the dividend payment date, or be deferred for payment to 
such date as determined by the Committee, in cash or in shares of 
unrestricted Stock having a Fair Market Value equal to the amount of such 
dividends.  Stock distributed in connection with a stock split or stock 
dividend, and other property distributed as a dividend, shall be subject to 
restrictions and a risk of forfeiture to the same extent as the Restricted 
Stock with respect to which such Stock or other property has been distributed.

               6.5  STOCK AWARDS IN LIEU OF CASH AWARDS.  The Committee is 
authorized to grant Stock to Grantees as a bonus, or to grant other Awards, 
in lieu of Company commitments to pay cash under other plans or compensatory 
arrangements.  Stock or Awards granted hereunder shall have such other terms 
as shall be determined by the Committee.

               6.6  OTHER STOCK-BASED OR CASH-BASED AWARDS.  The Committee is 
authorized to grant to Grantees Other Stock-Based Awards or Other Cash-Based 
Awards alone or in addition to any other Award under the Plan, as deemed by 
the Committee to be consistent with the purposes of the Plan.  Such Awards 
may be granted with value and payment contingent upon performance of the 
Company or any other factors designated by the Committee, or valued by 
reference to the performance of specified Subsidiaries or Affiliates.  

          The Committee shall determine the terms and conditions of such 
Awards at the date of grant or thereafter; PROVIDED, THAT performance 
objectives for each year shall be established by the Committee not later than 
the latest date permissible under Section 162(m) of the Code.  Such 
performance objectives may be expressed in terms of one or more financial or 
other objective goals. Financial goals may be expressed, for example, in 
terms of earnings per share, stock price, 


                                        12
<PAGE>

return on equity, net earnings growth, net earnings, related return ratios, 
cash flow, earnings before interest, taxes, depreciation and amortization 
(EBITDA), return on assets or total stockholder return.  Other objective 
goals may include the attainment of various productivity and long-term growth 
objectives.  Any criteria may be measured in absolute terms or as compared to 
another corporation or corporations.  To the extent applicable, any such 
performance objective shall be determined (a) in accordance with the 
Company's audited financial statements and generally accepted accounting 
principles and reported upon by the Company's independent accountants or (b) 
so that a third party having knowledge of the relevant facts could determine 
whether such performance objective is met.  Performance objectives shall 
include a threshold level of performance below which no Award payment shall 
be made, levels of performance above which specified percentages of target 
Awards shall be paid, and a maximum level of performance above which no 
additional Award shall be paid.  Performance objectives established by the 
Committee may be (but need not be) different from year-to-year and different 
performance objectives may be applicable to different Grantees.

          7.   CHANGE OF CONTROL PROVISIONS.  The following provisions shall 
apply in the event of a Change of Control, unless otherwise determined by the 
Committee or the Board in writing at or after grant (including under any 
individual agreement), but prior to the occurrence of such Change of Control:

               7.1  any Award carrying a right to exercise that was not 
previously exercisable and vested shall become fully exercisable and vested; 

               7.2  the restrictions, deferral limitations, payment 
conditions, and forfeiture conditions applicable to any other Award granted 
under the Plan shall lapse and such Awards shall be deemed fully vested, and 
any performance conditions imposed with respect to Awards shall be deemed to 
be fully achieved; and

               7.3  any indebtedness incurred pursuant to Section 8 of this 
Plan shall be forgiven and the collateral pledged in connection with any such 
Loan shall be released.

          8.   LOAN PROVISIONS.  Subject to the provisions of the Plan and all
applicable federal and state laws, rules and regulations (including the
requirements of Regulation G (12 C.F.R. Section  207)), the Committee shall 


                                        13
<PAGE>

have the authority to make Loans to Grantees (on such terms and conditions as 
the Committee shall determine), to enable such Grantees to purchase shares in 
connection with the Initial Public Offering or otherwise in connection with 
the realization of Awards under the Plan.  Loans shall be evidenced by a 
promissory note or other agreement, signed by the borrower, which shall 
contain provisions for repayment and such other terms and conditions as the 
Committee shall determine. 

          9.   GENERAL PROVISIONS.

               9.1  EFFECTIVE DATE; APPROVAL BY STOCKHOLDERS.  The Plan shall 
take effect upon its adoption by the Board (the "Effective Date"), but the 
Plan (and any grants of Awards made prior to the stockholder approval 
mentioned herein), shall be subject to the approval of the holder(s) of a 
majority of the issued and outstanding shares of voting securities of the 
Company entitled to vote, which approval must occur within twelve (12) months 
of the date the Plan is adopted by the Board.  In the absence of such 
approval, such Awards shall be null and void.  Notwithstanding the foregoing, 
the effectiveness of the Plan is conditioned upon the consummation of the 
Initial Public Offering, and shall be of no force and effect if the Initial 
Public Offering is not consummated.

               9.2  NONTRANSFERABILITY.  Awards shall not be transferable by 
a Grantee except by will or the laws of descent and distribution or, if then 
permitted under Rule 16b-3, pursuant to a qualified domestic relations order 
as defined under the Code or Title I of the Employee Retirement Income 
Security Act of 1974, as amended, or the rules thereunder, and shall be 
exercisable during the lifetime of a Grantee only by such Grantee or his 
guardian or legal representative.

               9.3  NO RIGHT TO CONTINUED EMPLOYMENT, ETC.  Nothing in the 
Plan or in any Award or Loan granted or any Award Agreement, promissory note 
or other agreement entered into pursuant hereto shall confer upon any Grantee 
the right to continue in the employ of or to continue as an independent 
contractor of the Company, any Subsidiary or any Affiliate, or to be entitled 
to any remuneration or benefits not set forth in the Plan or such Award 
Agreement, promissory note, or other agreement or to interfere with or limit 
in any way the right of the Company or any such Subsidiary or Affiliate to 
terminate such Grantee's employment or independent contractor relationship. 

               9.4  TAXES.  The Company or any Subsidiary or Affiliate is 
authorized to withhold from any Award granted, any payment relating to an 
Award under the Plan, including from a distribution of Stock, or any other 
payment to a


                                         14 
<PAGE>

Grantee, amounts of withholding and other taxes due in connection with any 
transaction involving an Award, and to take such other action as the 
Committee may deem advisable to enable the Company and Grantees to satisfy 
obligations for the payment of withholding taxes and other tax obligations 
relating to any Award.  This authority includes the authority to withhold or 
receive Stock or other property and to make cash payments in respect thereof 
in satisfaction of a Grantee's tax obligations.

               9.5  AMENDMENT AND TERMINATION OF THE PLAN.  The Board may at 
any time and from time to time alter, amend, suspend, or terminate the Plan 
in whole or in part; PROVIDED THAT, if the Committee determines that 
stockholder approval of an amendment is necessary and desirable in order for 
the Plan to comply or continue to comply with any applicable law, such 
amendment shall not be effective unless the same shall be approved by the 
requisite vote of the stockholders of the Company entitled to vote thereon. 
Notwithstanding the foregoing, no amendment shall affect adversely any of the 
rights of any Grantee, without such Grantee's consent, under any Award or 
Loan theretofore granted under the Plan.

               9.6  NO RIGHTS TO AWARDS OR LOANS; NO STOCKHOLDER RIGHTS.  No 
Grantee shall have any claim to be granted any Award or Loan under the Plan, 
and there is no obligation for uniformity of treatment of Grantees.   Except 
as provided specifically herein, a Grantee or a transferee of an Award shall 
have no rights as a stockholder with respect to any shares covered by the 
Award until the date of the issuance of a stock certificate to him for such 
shares.

               9.7  UNFUNDED STATUS OF AWARDS.  The Plan is intended to 
constitute an "unfunded" plan for incentive and deferred compensation.  With 
respect to any payments not yet made to a Grantee pursuant to an Award, 
nothing contained in the Plan or any Award shall give any such Grantee any 
rights that are greater than those of a general creditor of the Company.

               9.8  NO FRACTIONAL SHARES.  No fractional shares of Stock 
shall be issued or delivered pursuant to the Plan or any Award.  The 
Committee shall determine whether cash, other Awards, or other property shall 
be issued or paid in lieu of such fractional shares or whether such 
fractional shares or any rights thereto shall be forfeited or otherwise 
eliminated.

               9.9  REGULATIONS AND OTHER APPROVALS.


                                        15
<PAGE>

                    (a) The obligation of the Company to sell or deliver 
Stock with respect to any Award granted under the Plan shall be subject to 
all applicable laws, rules and regulations, including all applicable federal 
and state securities laws, and the obtaining of all such approvals by 
governmental agencies as may be deemed necessary or appropriate by the 
Committee.

                    (b) Each Award is subject to the requirement that, if at 
any time the Committee determines, in its absolute discretion, that the 
listing, registration or qualification of Stock issuable pursuant to the Plan 
is required by any securities exchange or under any state or federal law, or 
the consent or approval of any governmental regulatory body is necessary or 
desirable as a condition of, or in connection with, the grant of an Award or 
the issuance of Stock, no such Award shall be granted or payment made or 
Stock issued, in whole or in part, unless listing, registration, 
qualification, consent or approval has been effected or obtained free of any 
conditions not acceptable to the Committee.

                    (c) In the event that the disposition of Stock acquired 
pursuant to the Plan is not covered by a then current registration statement 
under the Securities Act and is not otherwise exempt from such registration, 
such Stock shall be restricted against transfer to the extent required by the 
Securities Act or regulations thereunder, and the Committee may require a 
Grantee receiving Stock pursuant to the Plan, as a condition precedent to 
receipt of such Stock, to represent to the Company in writing that the Stock 
acquired by such Grantee is acquired for investment only and not with a view 
to distribution.

               9.10  GOVERNING LAW.  The Plan and all determinations made and 
actions taken pursuant hereto shall be governed by the laws of the State of 
Maryland without giving effect to the conflict of laws principles thereof.

          (f)  The Managing Agent shall, promptly after receipt of a

     elects not to be so notified of Competitive Bid Requests, in which case 
     the Managing Agent shall not notify such Bank of the Competitive Bid 
     Request.

     be disregarded for purposes of this Agreement.  Any Competitive Bid made 
     by telephone shall promptly be confirmed by the delivery to the Managing 
     Agent in person or by telecopier of a written Competitive Bid.  The 
     Managing Agent shall incur no liability whatsoever hereunder in acting

          (h)  Each Competitive Bid shall specify the fixed interest rate or 
     the margin over the Eurodollar Rate, as applicable, for the offered 
     Maximum Competitive Advance set forth in the Competitive Bid.  The

     be less than the Competitive Advance requested by Borrower in the 
     Competitive Bid Request, but shall be an integral multiple of 
     $1,000,000.  Any Competitive Bid which offers an interest rate OTHER 
     THAN a fixed interest rate or a margin over the Eurodollar Rate, is in a 
     form other than set forth in EXHIBIT C or which otherwise contains any 
     term, condition or provision not contained in the Competitive Bid 
     Request shall be disregarded for purposes of this Agreement.  A

     irrevocable until 8:30 a.m. California time, in the case of a Eurodollar 
     Margin Bid, on the date which is three (3) Banking Days prior to the 
     requested Competitive Advance and, in the case of an Absolute Rate Bid, 
     on the date of the proposed Competitive Advance set forth in the related 
     Competitive Bid Request, and shall expire by its terms at such time 
     unless accepted by Borrower prior thereto.

          (i)  Promptly after 7:30 a.m. California time, in the case of a 
     Eurodollar Margin Bid, on the date which is four (4) Banking Days prior 
     to the date of the proposed Competitive Advance and, in the case of an 
     Absolute Rate Bid, on the date of the proposed Competitive Advance, the 
     Managing Agent shall notify Borrowers of the names of the Banks 
     providing Competitive Bids to the Managing Agent at or before 7:30 a.m. 
     on that date (or 7:15 a.m. in the case of the Domestic Reference Bank) 
     and the Maximum Competitive Advance and fixed interest rate or margin 
     over the Eurodollar Rate set forth by each such Bank in its Competitive 
     Bid.  The Managing Agent shall promptly confirm such notification in 
     writing delivered in person or by telecopier to Borrower.

          (j)  Borrowers may, in their sole and absolute discretion, reject 
     any or all of the Competitive Bids.  If Borrowers accept any Competitive 
     Bid, the following shall apply:  (i) Borrowers must accept all Absolute 
     Rate Bids at all lower fixed interest rates before accepting any portion 
     of an Absolute Rate Bid at a higher fixed interest rate, (ii) Borrowers 
     must accept all Eurodollar Margin Bids at all lower margins over the 
     Eurodollar Rate before accepting any 


                                       -42-

<PAGE>

     portion of a Eurodollar Margin Bid at a higher margin over the Eurodollar 
     Rate, (iii) if two or more Banks have submitted a Competitive Bid at the 
     same fixed interest rate or margin, then Borrowers must accept either all 
     of such Competitive Bids or accept such Competitive Bids in the same 
     proportion as the Maximum Competitive Advance of each Bank bears to the 
     aggregate Maximum Competitive Advances of all such Banks, and 
     (iv) Borrowers may not accept Competitive Bids for an aggregate amount in 
     excess of the requested Competitive Advance set forth in the Competitive 
     Bid Request.  Acceptance by Borrowers of a Eurodollar Margin Rate Bid must

     prior to the requested Competitive Advance and acceptance by Borrower of 
     an Absolute Rate Bid must be made prior to 8:30 a.m. on the date of the 
     requested Competitive Advance.  Acceptance of a Competitive Bid by 
     Borrowers shall be accomplished by notification thereof to the Managing 
     Agent and shall be irrevocable upon such notification.  The Managing 
     Agent shall promptly notify each of the Banks whose Competitive Bid has 
     been accepted by Borrowers by telephone, which notification shall 
     promptly be confirmed in writing delivered in person or by telecopier to 
     such Banks.  Any Competitive Bid not accepted by Borrowers by 8:30 a.m., 
     in the case of a Eurodollar Margin Bid, on the date which is three (3) 
     Banking Days prior to the proposed Competitive Advance or, in the case 
     of an Absolute Rate Bid, on the date of the proposed Competitive Bid, 
     shall be deemed rejected.

          (k)  In the case of a Eurodollar Margin Bid, the Managing Agent 
     shall determine the Eurodollar Rate on the date which is two 
     (2) Eurodollar Banking Days prior to the date of the proposed Competitive 
     Advance, and shall promptly thereafter notify Borrowers and the Banks 
     whose Eurodollar Margin Bids were accepted by Borrowers of such 
     Eurodollar Rate.

          (l)  A Bank whose Competitive Bid has been accepted by Borrowers 
     shall make the Competitive Advance in accordance with the Competitive 
     Bid Request and with its Competitive Bid, subject to the applicable 
     conditions set forth in this Agreement, by making funds immediately 
     available to the Managing Agent at the Managing Agent's Office in the 
     amount of such Competitive Advance not later than 12:00 noon, California 
     time, on the date set forth in the Competitive Bid Request.  The 
     Managing Agent shall then promptly credit the Competitive Advance in 
     immediately available funds to the 


                                       -43-

Designated Deposit Account.

          (m)  The Managing Agent shall notify Borrowers and the Banks 
     promptly after any Competitive Advance is made of the amounts and 
     maturity of such Competitive Advances and the identity of the Banks 
     making such Competitive Advances.

          (n)  The Competitive Advances made by a Bank shall be evidenced by 
     that Bank's Competitive Advance Note.

          (o)  No Competitive Advance may be prepaid without the prior 
     written consent of the affected Bank.

     2.5  VOLUNTARY REDUCTION OF COMMITMENTS.  Borrowers shall have the 
right, at any time and from time to time, without penalty or charge, upon at 
least three (3) Banking Days' prior written notice by a Responsible Official 
of Borrowers to the Managing Agent, voluntarily to reduce, permanently and 
irrevocably, in aggregate principal amounts in an integral multiple of 
$1,000,000 but not less than $5,000,000, or to terminate, all or a portion of 
the then undisbursed portion of the Commitments.  The Managing Agent shall 
promptly notify the Banks of any reduction or termination of the Commitments 
under this Section.

     2.6  AUTOMATIC REDUCTION OF COMMITMENTS.  On each Amortization Date, the 
Commitments shall automatically be reduced by the applicable Amortization 
Amount.

     2.7  OPTIONAL TERMINATION OF COMMITMENTS.  Following the occurrence of a 
Change in Control, the Requisite Banks may in their sole and absolute 
discretion elect, during the thirty (30) day period immediately subsequent to 
the LATER OF (a) such occurrence or (b) the EARLIER of (i) receipt of 
Borrowers' written notice to the Managing Agent of such occurrence or (ii) if 
no such notice has been received by the Managing Agent, the date upon which 
the Managing Agent has actual knowledge thereof, to terminate the 
Commitments, in which case the Commitments shall be terminated effective on 
the date which is thirty (30) days subsequent to written notice from the 
Managing Agent to Borrowers thereof.

     2.8  MANAGING AGENT'S RIGHT TO ASSUME FUNDS AVAILABLE FOR ADVANCES.  
Unless the Managing Agent shall have been notified by any Bank no later than 
10:00 a.m. on the Banking Day of the proposed funding by the Managing Agent 
of any Loan that such Bank does not intend to make available to the Managing 
Agent such Bank's portion of the total amount of such Loan, the Managing 
Agent may assume that such Bank has made such amount available to the 
Managing Agent on the date of the Loan and the Managing Agent may, in 
reliance upon such assumption, make available to Borrowers a corresponding 
amount.  If the Managing Agent has made funds available to Borrowers based on 
such assumption and such corresponding amount is not in fact made available 
to the Managing Agent by such Bank, the Managing Agent shall be entitled to 
recover such corresponding amount on demand from such Bank.  If such Bank 
does not pay such corresponding amount forthwith upon the Managing Agent's 
demand therefor, the Managing Agent promptly shall notify Borrowers and 
Borrowers shall pay such corresponding amount to the Managing Agent.  The 
Managing Agent also shall be entitled to recover from such Bank interest on 
such corresponding amount in respect of each day from the date such 
corresponding amount was made available by the Managing Agent to Borrowers to 
the date such corresponding amount is recovered by the Managing Agent, at a 
rate per annum equal to the daily Federal Funds Rate.  Nothing herein shall 
be deemed to relieve any Bank from its obligation to fulfill its share of the 
Commitments or to prejudice any rights which the Managing Agent or Borrowers 
may have against any Bank as a result of any default by such Bank hereunder.

     2.9  EXTENSION OF REVOLVER TERMINATION DATE.

          (a)  The Revolver Termination Date may be extended for one-year 
     periods at the request of Borrowers and with the written consent of all 
     of the Banks (which may be withheld in the sole and absolute discretion 
     of each Bank) pursuant to this Section.  Not earlier than June 1, 1998 
     nor later than July 1, 1998, or in the corresponding period in each 
     subsequent year, and provided that Borrowers are then in compliance with 
     Section 7.1, Borrowers may deliver to the Managing Agent and the Banks a 
     written request for a one year extension of the Revolver Termination 
     Date together with a Certificate of a Responsible Official signed by a 
     Senior Officer on behalf of Borrowers stating that the representations 
     and warranties contained in ARTICLE 4 (OTHER THAN (i) representations 
     and warranties which expressly speak as of a particular date 


                                       -45-
<PAGE>

     or are no longer true and correct as a result of a change which is not a 
     violation of this Agreement and (ii) as otherwise disclosed by Borrowers 
     and approved in writing by the Requisite Banks are true and correct on and 
     as of the date of such Certificate).  Each Bank shall, on or prior to 
     the date that is sixty (60) days after receipt of such written request, 
     notify in writing the Managing Agent whether (in its sole and absolute 
     discretion) it consents to such request and the Managing Agent shall, 
     after receiving the notifications from all of the Banks or the 
     expiration of such period, whichever is earlier, notify Borrowers and 
     the Banks of the results thereof.  If all of the Banks have consented, 
     then the Revolver Termination Date shall be automatically extended for 
     one year upon payment by Borrowers to the Managing Agent of the 
     extension fee pursuant to Section 3.6.

          (b)  If Banks holding 80% or more of the Commitments (the 
     "Approving Banks") consent to the request for extension, but one or more 
     Banks (the "Disapproving Banks") notifies the Managing Agent that it 
     will not consent to the request for extension (or fails to notify the 
     Managing Agent in writing of its consent to the extension by the date 
     that is sixty (60) days after receipt of such written request), 
     Borrowers may at their option reduce the Commitments by an amount equal 
     to the amount thereof held by the Disapproving Banks, adjust the 
     Pro-Rata Shares (but not the amount) of the reduced Commitments of the 
     Approving Banks to correspond with the reduced Commitments and, subject 
     to the further written consent of all the Approving Banks, the Revolver 
     Termination Date shall automatically be extended for one year upon 
     payment by Borrowers to the Managing Agent of the extension fee pursuant 
     to Section 3.6.

          (c)  If Banks holding 80% or more of the Commitments do not consent 
     to the request for extension, Borrowers may, within the thirty (30) day 
     period following expiration of the aforesaid sixty (60) day period, 
     cause the Disapproving Banks to assign their Pro-Rata Shares of the 
     Commitments to an Eligible Assignee acceptable to Borrowers and the 
     Managing Agent pursuant to Section 11.25.  Upon completion of such 
     assignments, the request for extension shall be renewed and, subject to 
     the written consent of all of the Banks (INCLUDING the new Banks), the 
     Revolver Termination Date shall automatically be extended for one year 
     upon payment by Borrowers to the Managing Agent of the extension fee 
     pursuant to Section 3.6.

the credit facility under this Agreement to a term loan by delivery of a 
written notice to that effect to the Managing Agent and payment of the 
extension fee payable pursuant to Section 3.6.  The Line A Notes and the 
Line A Notes will continue to evidence the outstanding Indebtedness incurred 
under the Line A Commitment and the Line B Commitment subsequent to such 
conversion.  The term loan so elected shall commence on the Conversion Date 
and shall be payable in Amortization Amounts on each Amortization Date.

     2.11 UNENCUMBERED ASSET POOL.  Borrowers may at any time add a Qualified 
Unencumbered Asset Pool Property to the Unencumbered Asset Pool pursuant to 
this Section 2.11, which process shall be initiated by delivery by Borrowers 
to the Managing Agent (which the Managing Agent shall promptly distribute to 
the Banks) of a complete description of the Qualified Unencumbered Asset Pool 
Property, at least two (2) years of operating income statements related 
thereto (to the extent available), a description of all tenants and leases 
with respect thereto, a current written report prepared by a qualified 
independent expert with respect to Hazardous Materials related thereto and 
other written materials reasonably requested by any Bank.  Thereafter:

          (a)  If at that date either of the Consent Criteria is satisfied, 
     the Qualified Unencumbered Asset Pool Property so described shall 
     thereupon become part of the Unencumbered Asset Pool; or

          (b)  If at that date neither of the Consent Criteria is satisfied, 
     the Qualified Unencumbered Asset Pool Property so described shall become 
     part of the Unencumbered Asset Pool on the tenth (10th) day after the 
     date the aforesaid descriptive materials are delivered to the Managing 
     Agent UNLESS on or before such day Banks holding 51% or more of the 
     Commitments have notified Borrowers and the Managing Agent in writing 
     that they object to the addition of such Qualified Unencumbered Asset 
     Pool Property to the Unencumbered Asset Pool, which notifications shall 
     state the reason or reasons for such objection.

Borrowers may remove a Revenue-Producing Property from the Unencumbered Asset 
Pool by delivery to the Managing Agent (for distribution to the Banks) of a 
written

Borrowers setting forth the revised Borrowing Base as of the most 
recently-ended Fiscal Quarter resulting from such removal, which removal 
shall be effective on the tenth (10th) day after the date of such notice.

     2.12 REPRESENTATIVE OF BORROWERS.  Each of Borrowers hereby appoints 
Parent as its agent, attorney-in-fact and representative for the purpose of 
making Requests for Loans, Competitive Bid Requests, acceptance of 
Competitive Bids, payment and prepayment of Loans and Competitive Advances, 
the giving and receipt of notices by and to Borrowers under this Agreement 
and all other purposes incidental to any of the foregoing.  Each of Borrowers 
agrees that any action taken by Parent as the agent, attorney-in-fact and 
representative of such Borrower shall be binding on such Borrowers to the 
same extent as if directly taken by such Borrower.

therein or any change in the interpretation or administration thereof by any

administration thereof, or compliance by such Bank (or its Eurodollar Lending

or directive regarding capital adequacy (whether or not having the force of 
Law) of any such central bank or other authority not imposed as a result of 
such Bank's or such corporation's failure to comply with any other Laws, 
affects or would affect the amount of capital required or expected to be 
maintained by such Bank or any corporation controlling such Bank and (taking 
into consideration such Bank's or such corporation's policies with respect to 
capital adequacy and such Bank's desired return on capital) determines in 
good faith that the amount of such capital is increased, or the rate of 
return on capital is reduced, as a consequence of its obligations under this 
Agreement, then, within ten (10) Banking Days after demand of such Bank, 
Borrowers shall pay to such Bank, from time to time as specified in good 
faith by such Bank, additional amounts sufficient to compensate such Bank in 
light of such circumstances, to the extent reasonably allocable to such

obligated to pay any such amount which arose prior to the date which is 
ninety (90) days preceding the date of such demand or is attributable to

such demand.  Each Bank's determination of such amounts shall

     Obligations of that Bank, Borrowers shall pay that Bank within five (5) 
     Banking Days after demand all amounts necessary to compensate such Bank 
     (determined as though such Bank's Eurodollar Lending Office had funded 
     100% of its Eurodollar Rate Advance in the Designated Eurodollar Market)

     that Borrowers shall not be obligated to pay any such amount which arose 
     prior to the date which is ninety (90) days preceding the date of such 
     demand or is attributable to periods prior to the date which is ninety 
     (90) days preceding the date of such demand).  The Bank's determination 
     of such amount shall be conclusive in the absence of manifest error.

              (b)  If, after the date hereof, the existence or occurrence of 
     any Special Eurodollar Circumstance:

                   (1)  shall subject any Bank or its Eurodollar Lending

          Eurodollar Rate Advance, any of its Notes evidencing Eurodollar 
          Rate Loans or its obligation to make Eurodollar Rate Advances, or 
          shall change the basis of taxation of payments to any Bank 
          attributable to the principal of or interest on any Eurodollar Rate 
          Advance or any other amounts due under this Agreement in respect of 
          any Eurodollar Rate Advance, any of its Notes evidencing Eurodollar 
          Rate Loans or its obligation to make Eurodollar Rate Advances 
          (PROVIDED, that Borrowers shall not be obligated to pay any such 
          amount which arose prior to the date which is ninety (90) days 
          preceding the date of such demand or is attributable to periods 
          prior to the date which is ninety (90) days preceding the date of 
          such demand), EXCLUDING (i) taxes imposed on or measured in whole 
          or in part by its overall net income by (A) any jurisdiction (or 
          political subdivision thereof) in which it is organized or 
          maintains its principal office or Eurodollar Lending Office or (B) 
          any

          "doing business" and (ii) any withholding taxes or other taxes 
          based on gross income imposed by the United States of America for

          the extent such forms are then required by applicable Laws;

              (2)  shall impose, modify or deem applicable any reserve not 
          applicable or deemed applicable on the date hereof (INCLUDING any 
          reserve imposed by the Board of Governors of the Federal Reserve 
          System, special deposit, capital or similar requirements against 
          assets of, deposits with or for the account of, or credit extended 
          by, any Bank or its Eurodollar Lending Office); or

              (3)  shall impose on any Bank or its Eurodollar Lending Office 
          or the Designated Eurodollar Market any other condition affecting 
          any Eurodollar Rate Advance, any of its Notes evidencing Eurodollar 
          Rate Loans, its obligation to make Eurodollar Rate Advances or this 
          Agreement, or shall otherwise affect any of the same;

     and the result of any of the foregoing, as determined in good faith by 
     such Bank, increases the cost to such Bank or its Eurodollar Lending 
     Office of making or maintaining any Eurodollar Rate Advance or in 
     respect of any Eurodollar Rate Advance, any of its Notes evidencing 
     Eurodollar Rate Loans or its obligation to make Eurodollar Rate Advances 
     or reduces the amount of any sum received or receivable by such Bank or 
     its Eurodollar Lending Office with respect to any Eurodollar Rate 
     Advance, any of its Notes evidencing Eurodollar Rate Loans or its 
     obligation to make Eurodollar Rate Advances (assuming such Bank's 
     Eurodollar Lending Office had funded 100% of its Eurodollar Rate Advance 
     in the Designated Eurodollar Market), then, within five (5) Banking Days 
     after demand by such Bank (with a copy to the Managing Agent), Borrowers 
     shall pay to such Bank such additional amount or amounts as will 
     compensate such Bank for such increased cost or reduction (determined as 
     though such Bank's Eurodollar Lending Office had funded 100% of its 
     Eurodollar Rate Advance in the Designated Eurodollar Market).  A 
     statement of any Bank claiming compensation under this subsection shall 
     be conclusive in the absence of manifest error.

         (c)  If, after the date hereof, the existence or occurrence of any 
     Special Eurodollar Circumstance shall, in the good faith opinion of any 
     Bank, make it unlawful or impossible for such Bank or its Eurodollar 
     Lending Office to make, maintain or fund its portion of any Eurodollar 
     Rate Loan, or materially restrict the authority of such Bank to purchase 
     or sell, or to take deposits of, Dollars in the Designated Eurodollar 
     Market, or to determine or charge interest rates based upon the 
     Eurodollar Rate, and such Bank shall so notify the Managing Agent, then 
     such Bank's obligation to make Eurodollar Rate Advances shall be 
     suspended for the duration of such illegality or impossibility and the 
     Managing Agent forthwith shall give notice thereof to the other Banks 
     and Borrowers. Upon receipt of such notice, the outstanding principal 
     amount of such Bank's Eurodollar Rate Advances, together with accrued 
     interest thereon, automatically shall be converted to Alternate Base 
     Rate Advances on either (1) the last day of the Eurodollar Period(s) 
     applicable to such Eurodollar Rate Advances if such Bank may lawfully 
     continue to maintain and fund such Eurodollar Rate Advances to such 
     day(s) or (2) immediately if such Bank may not lawfully continue to fund 
     and maintain such Eurodollar Rate Advances to such day(s), PROVIDED that 
     in such event the conversion shall not be subject to payment of a 
     prepayment fee under Section 3.8(e).  Each Bank agrees to endeavor 
     promptly to notify Borrowers of any event of which it has actual 
     knowledge, occurring after the Closing Date, which will cause that Bank 
     to notify the Managing Agent under this Section, and agrees to designate 
     a different Eurodollar Lending Office if such designation will avoid the 
     need for such notice and will not, in the good faith judgment of such 
     Bank, otherwise be materially disadvantageous to such Bank.  In the 
     event that any Bank is unable, for the reasons set forth above, to make, 
     maintain or fund its portion of any Eurodollar Rate Loan, such Bank 
     shall fund such amount as an Alternate Base Rate Advance for the same 
     period of time, and such amount shall be treated in all respects as an 
     Alternate Base Rate Advance.  Any Bank whose obligation to make 
     Eurodollar Rate Advances has been suspended under this Section shall 
     promptly notify the Managing Agent and Borrowers of the cessation of the 
     Special Eurodollar Circumstance which gave rise to such suspension.

         (d)  If, with respect to any proposed Eurodollar Rate Loan:

              (1)  the Managing Agent reasonably determines that, by 


                                        -55-
<PAGE>

          reason of circumstances affecting the Designated Eurodollar Market 
          generally that are beyond the reasonable control of the Banks, 
          deposits in Dollars (in the applicable amounts) are not being 
          offered to any Bank in the Designated Eurodollar Market for the 
          applicable Eurodollar Period; or

              (2)  the Requisite Banks advise the Managing Agent that the 
          Eurodollar Rate as determined by the Managing Agent (i) does not 
          represent the effective pricing to such Banks for deposits in 
          Dollars in the Designated Eurodollar Market in the relevant amount 
          for the applicable Eurodollar Period, or (ii) will not adequately 
          and fairly reflect the cost to such Banks of making the applicable 
          Eurodollar Rate Advances;

     then the Managing Agent forthwith shall give notice thereof to Borrowers 
     and the Banks, whereupon until the Managing Agent notifies Borrowers 
     that the circumstances giving rise to such suspension no longer exist, 
     the obligation of the Banks to make any future Eurodollar Rate Advances 
     shall be suspended.

         (e)  Upon payment or prepayment of any Eurodollar Rate Advance 
     (OTHER THAN as the result of a conversion required under Section 3.8(c) 
     on a day other than the last day in the applicable Eurodollar Period 
     (whether voluntarily, involuntarily, by reason of acceleration, or 
     otherwise), or upon the failure of Borrowers (for a reason other than 
     the breach by a Bank of its obligation pursuant to Sections 2.1(a) or 
     2.1(b) to make an Advance) to borrow on the date or in the amount 
     specified for a Eurodollar Rate Loan in any Request for Loan, Borrowers 
     shall pay to the appropriate Bank within ten (10) Banking Days after 
     demand a prepayment fee or failure to borrow fee, as the case may be 
     (determined as though 100% of the Eurodollar Rate Advance had been 
     funded in the Designated Eurodollar Market) equal to the SUM of:

              (1)  $250; PLUS

              (2)  the amount, if any, by which (i) the additional interest 
          would have accrued on the amount prepaid or not borrowed at the 
          Eurodollar Rate PLUS the Applicable Eurodollar Rate Margin if that 
          amount had remained or been outstanding through the last day of the 
          applicable Interest Period EXCEEDS (ii) the interest that the Bank 
          could 


                                        -56-
<PAGE>

          recover by placing such amount on deposit in the Designated 
          Eurodollar Market for a period beginning on the date of the 
          prepayment or failure to borrow and ending on the last day of the 
          applicable Interest Period (or, if no deposit rate quotation is 
          available for such period, for the most comparable period for which 
          a deposit rate quotation may be obtained); PLUS

              (3)  all out-of-pocket expenses incurred by the Bank reasonably 
          attributable to such payment, prepayment or failure to borrow.

     Each Bank's determination of the amount of any prepayment fee 
     payable under this Section shall be conclusive in the absence of 
     manifest error.

         (f)  Each Bank agrees to endeavor promptly to notify Borrowers of 
     any event of which it has actual knowledge, occurring after the Closing 
     Date, which will entitle such Bank to compensation pursuant to clause 
     (a) or clause (b) of this Section 3.8, and agrees to designate a 
     different Eurodollar Lending Office if such designation will avoid the 
     need for or reduce the amount of such compensation and will not, in the 
     good faith judgment of such Bank, otherwise be materially 
     disadvantageous to such Bank.  Any request for compensation by a Bank 
     under this Section 3.8 shall set forth the basis upon which it has been 
     determined that such an amount is due from Borrowers, a calculation of 
     the amount due, and a certification that the corresponding costs have 
     been incurred by the Bank.

    3.9  LATE PAYMENTS.  If any installment of principal or interest or any 
fee or cost or other amount payable under any Loan Document to the Managing 
Agent or any Bank is not paid when due, it shall thereafter bear interest at 
a fluctuating interest rate per annum at all times equal to the SUM OF the 
Alternate Base Rate PLUS the Applicable Alternate Base Rate Margin PLUS 2%, 
to the fullest extent permitted by applicable Laws.  Accrued and unpaid 
interest on past due amounts (INCLUDING, without limitation, interest on past 
due interest) shall be compounded monthly, on the last day of each calendar 
month, to the fullest extent permitted by applicable Laws.

    3.10  COMPUTATION OF INTEREST AND FEES.  Computation of interest and fees 
under this Agreement shall be calculated on the basis of a year of 360 days 
and the 


                                        -57-
<PAGE>

actual number of days elapsed.  Interest shall accrue on each Loan for the 
day on which the Loan is made; interest shall not accrue on a Loan, or any 
portion thereof, for the day on which the Loan or such portion is paid.  Any 
Loan that is repaid on the same day on which it is made shall bear interest 
for one day. Notwithstanding anything in this Agreement to the contrary, 
interest in excess of the maximum amount permitted by applicable Laws shall 
not accrue or be payable hereunder or under the Notes, and any amount paid as 
interest hereunder or under the Notes which would otherwise be in excess of 
such maximum permitted amount shall instead be treated as a payment of 
principal.

    3.11  NON-BANKING DAYS.  If any payment to be made by Borrowers or any 
other Party under any Loan Document shall come due on a day other than a 
Banking Day, payment shall instead be considered due on the next succeeding 
Banking Day and the extension of time shall be reflected in computing 
interest and fees.

    3.12  MANNER AND TREATMENT OF PAYMENTS.

         (a)  Each payment hereunder (EXCEPT payments pursuant to Sections 
     3.7, 3.8, 11.3, 11.11 and 11.22) or on the Notes or under any other Loan 
     Document shall be made to the Managing Agent at the Managing Agent's 
     Office for the account of each of the Banks or the Managing Agent, as 
     the case may be, in immediately available funds not later than 11:00 
     a.m. California time, on the day of payment (which must be a Banking 
     Day).  All payments received after such time, on any Banking Day, shall 
     be deemed received on the next succeeding Banking Day.  The amount of 
     all payments received by the Managing Agent for the account of each Bank 
     shall be immediately paid by the Managing Agent to the applicable Bank 
     in immediately available funds and, if such payment was received by the 
     Managing Agent by 11:00 a.m., California time, on a Banking Day and not 
     so made available to the account of a Bank on that Banking Day, the 
     Managing Agent shall reimburse that Bank for the cost to such Bank of 
     funding the amount of such payment at the Federal Funds Rate.  All 
     payments shall be made in lawful money of the United States of America. 
         (b)  Each payment or prepayment on account of any Loan shall be applied
     pro rata according to the outstanding Advances made by each Bank 
     comprising such Loan.

         (c)  Each Bank shall use its best efforts to keep a record (in 


                                        -58-

<PAGE>

     writing or by an electronic data entry system) of Advances made by it 
     and payments received by it with respect to each of its Notes and, 
     subject to Section 10.6(g), such record shall, as against Borrowers, be 
     presumptive evidence of the amounts owing. Notwithstanding the foregoing 
     sentence, the failure by any Bank to keep such a record shall not affect 
     Borrowers' obligation to pay the Obligations.

              (d)  Each payment of any amount payable by Borrowers or any 
     other Party under this Agreement or any other Loan Document shall be 
     made free and clear of, and without reduction by reason of, any taxes, 
     assessments or other charges imposed by any Governmental Agency, central 
     bank or comparable authority, EXCLUDING (i) taxes imposed on or measured 
     in whole or in part by its overall net income by (A) any jurisdiction 
     (or political subdivision thereof) in which it is organized or maintains 
     its principal office or Eurodollar Lending Office or (B) any 
     jurisdiction (or political subdivision thereof) in which it is "doing 
     business" and (ii) any withholding taxes or other taxes based on gross 
     income imposed by the United States of America for any period with 
     respect to which it has failed to provide Borrowers with the appropriate 
     form or forms required by Section 11.21, to the extent such forms are 
     then required by applicable Laws (all such non-excluded taxes, 
     assessments or other charges being hereinafter referred to as "Taxes").  
     To the extent that Borrowers are obligated by applicable Laws to make 
     any deduction or withholding on account of Taxes from any amount payable 
     to any Bank under this Agreement, Borrowers shall (i) make such 
     deduction or withholding and pay the same to the relevant Governmental 
     Agency and (ii) pay such additional amount to that Bank as is necessary 
     to result in that Bank's receiving a net after-Tax amount equal to the 
     amount to which that Bank would have been entitled under this Agreement 
     absent such deduction or withholding.  If and when receipt of such 
     payment results in an excess payment or credit to that Bank on account 
     of such Taxes, that Bank shall promptly refund such excess to Borrowers.

         3.13  FUNDING SOURCES.  Nothing in this Agreement shall be deemed to 
obligate any Bank to obtain the funds for any Loan or Advance in any 
particular place or manner or to constitute a representation by any Bank that 
it has obtained or will obtain the funds for any Loan or Advance in any 
particular place or manner.

         3.14  FAILURE TO CHARGE NOT SUBSEQUENT WAIVER.  Any decision by the 


                                        -59-
<PAGE>

Managing Agent or any Bank not to require payment of any interest (INCLUDING 
interest arising under Section 3.9), fee, cost or other amount payable under 
any Loan Document, or to calculate any amount payable by a particular method, 
on any occasion shall in no way limit or be deemed a waiver of the Managing 
Agent's or such Bank's right to require full payment of any interest 
(INCLUDING interest arising under Section 3.9), fee, cost or other amount 
payable under any Loan Document, or to calculate an amount payable by another 
method that is not inconsistent with this Agreement, on any other or 
subsequent occasion.

         3.15  MANAGING AGENT'S RIGHT TO ASSUME PAYMENTS WILL BE MADE BY 
BORROWERS. Unless the Managing Agent shall have been notified by Borrowers 
prior to the date on which any payment to be made by Borrowers hereunder is 
due that Borrowers do not intend to remit such payment, the Managing Agent 
may, in its discretion, assume that Borrowers have remitted such payment when 
so due and the Managing Agent may, in its discretion and in reliance upon 
such assumption, make available to each Bank on such payment date an amount 
equal to such Bank's share of such assumed payment.  If Borrowers have not in 
fact remitted such payment to the Managing Agent, each Bank shall forthwith 
on demand repay to the Managing Agent the amount of such assumed payment made 
available to such Bank, together with interest thereon in respect of each day 
from and including the date such amount was made available by the Managing 
Agent to such Bank to the date such amount is repaid to the Managing Agent at 
the Federal Funds Rate.

         3.16  FEE DETERMINATION DETAIL.  The Managing Agent, and any Bank, 
shall provide reasonable detail to Borrowers regarding the manner in which 
the amount of any payment to the Managing Agent and the Banks, or that Bank, 
under ARTICLE 3 has been determined, concurrently with demand for such 
payment.

         3.17  SURVIVABILITY.  All of Borrowers' obligations under Sections 
3.7 and 3.8 shall survive for the ninety (90) day period following the date 
on which the Commitments are terminated and all Loans hereunder are fully 
paid, and Borrowers shall remain obligated thereunder for all claims under 
such Sections made by any Bank to Borrowers prior to the expiration of such 
period.

                            REPRESENTATIONS AND WARRANTIES


         Borrowers represent and warrant to the Banks that:

         4.1  EXISTENCE AND QUALIFICATION; POWER; COMPLIANCE WITH LAWS.  
Parent is a corporation duly formed, validly existing and in good standing 
under the Laws of Maryland and each other Borrower is a corporation or 
limited liability company duly formed, validly existing and in good standing 
under the Laws of its state of formation.  Each of Borrowers is duly 
qualified or registered to transact business and is in good standing in each 
other jurisdiction in which the conduct of its business or the ownership or 
leasing of its Properties makes such qualification or registration necessary, 
EXCEPT where the failure so to qualify or register and to be in good standing 
would not constitute a Material Adverse Effect.  Each of Borrowers has all 
requisite power and authority to conduct its business, to own and lease its 
Properties and to execute and deliver each Loan Document to which it is a 
Party and to perform its Obligations.  All outstanding shares of capital 
stock of Parent are duly authorized, validly issued, fully paid and 
non-assessable, and no holder thereof has any enforceable right of rescission 
under any applicable state or federal securities Laws.  Each of Borrowers is 
in compliance with all Laws and other legal requirements applicable to its 
business, has obtained all authorizations, consents, approvals, orders, 
licenses and permits from, and has accomplished all filings, registrations 
and qualifications with, or obtained exemptions from any of the foregoing 
from, any Governmental Agency that are necessary for the transaction of its 
business, EXCEPT where the failure so to comply, obtain authorizations, etc., 
file, register, qualify or obtain exemptions does not constitute a Material 
Adverse Effect.  Parent is a "real estate investment trust" within the 
meaning of Section 856 of the Code.

         4.2  AUTHORITY; COMPLIANCE WITH OTHER AGREEMENTS AND INSTRUMENTS AND 
GOVERNMENT REGULATIONS.  The execution, delivery and performance by each of 
Borrowers of the Loan Documents to which it is a Party have been duly 
authorized by all necessary corporate action, and do not and will not:

              (a)  Require any consent or approval not heretofore obtained of 
     any partner, director, stockholder, security holder or creditor of 
     Borrowers;


                                        -61-
<PAGE>

              (b)  Violate or conflict with any provision of Borrowers' 
     charter, articles of incorporation or bylaws, as applicable;

              (c)  Result in or require the creation or imposition of any 
     Lien or Right of Others upon or with respect to any Property now owned 
     or leased or hereafter acquired by Borrowers;

              (d)  Violate any Requirement of Law applicable to Borrowers;

              (e)  Result in a breach of or constitute a default under, or 
     cause or permit the acceleration of any obligation owed under, any 
     indenture or loan or credit agreement or any other Contractual 
     Obligation to which Borrowers are a party or by which Borrowers or any 
     of their Property is bound or affected;

and none of Borrowers is in violation of, or default under, any Requirement 
of Law or Contractual Obligation, or any indenture, loan or credit agreement 
described in Section 4.2(e), in any respect that constitutes a Material 
Adverse Effect.

         4.3  NO GOVERNMENTAL APPROVALS REQUIRED.  EXCEPT as previously 
obtained or made, no authorization, consent, approval, order, license or 
permit from, or filing, registration or qualification with, any Governmental 
Agency is or will be required to authorize or permit under applicable Laws 
the execution, delivery and performance by any of Borrowers of the Loan 
Documents to which it is a Party.

         4.4  SUBSIDIARIES.  SCHEDULE 4.4 hereto correctly sets forth the 
names, form of legal entity, number of shares of capital stock (or other 
applicable unit of equity interest) issued and outstanding, and the record 
owner thereof and jurisdictions of organization of all Subsidiaries of 
Parent.  Unless otherwise indicated in SCHEDULE 4.4, all of the outstanding 
shares of capital stock, or all of the units of equity interest, as the case 
may be, of each such Subsidiary are owned of record and beneficially by 
Parent, there are no outstanding options, warrants or other rights to 
purchase capital stock of any such Subsidiary, and all such shares or equity 
interests so owned are duly authorized, validly issued, fully paid and 
non-assessable, and were issued in compliance with all applicable state and 
federal securities and other Laws, and are free and clear of all Liens and 
Rights of Others, EXCEPT for Permitted Encumbrances and Permitted Rights of 
Others.


                                        -62-
<PAGE>

         4.5  FINANCIAL STATEMENTS.  Borrowers have furnished to the Banks 
(a) the audited consolidated financial statements of Parent and its 
Subsidiaries for the Fiscal Year ended December 31, 1996 and (b) the 
unaudited consolidated balance sheet and statement of operations of Parent 
and its Subsidiaries for the Fiscal Quarter ended March 31, 1997.  The 
financial statements described in clause (a) fairly present in all material 
respects the financial condition, results of operations and changes in 
financial position, and the balance sheet and statement of operations 
described in clause (b) fairly present the financial condition and results of 
operations of Parent and its Subsidiaries as of such dates and for such 
periods in conformity with Generally Accepted Accounting Principles 
consistently applied.

         4.6  NO OTHER LIABILITIES; NO MATERIAL ADVERSE CHANGES.  Borrowers 
do not have any material liability or material contingent liability required 
under Generally Accepted Accounting Principles to be reflected or disclosed, 
and not reflected or disclosed, in the balance sheet described in 
Section 4.5(b), OTHER THAN liabilities and contingent liabilities arising in 
the ordinary course of business since the date of such financial statements.  
As of the Closing Date, no circumstance or event has occurred that constitutes 
a Material Adverse Effect since March 31, 1997.  As of any date subsequent to 
the Closing Date, no circumstance or event has occurred that constitutes a 
Material Adverse Effect since the Closing Date.

         4.7  TITLE TO PROPERTY.  Borrowers have valid title to the Property 
(OTHER THAN assets which are the subject of a Capital Lease Obligation) 
reflected in the balance sheet described in Section 4.5(b), OTHER THAN items 
of Property or exceptions to title which are in each case immaterial to 
Borrowers and Property subsequently sold or disposed of in the ordinary 
course of business.  Such Property is free and clear of all Liens and Rights 
of Others, OTHER THAN Liens or Rights of Others described in SCHEDULE 4.7 and 
Permitted Encumbrances and Permitted Rights of Others.

         4.8  INTANGIBLE ASSETS.  Borrowers own, or possess the right to use 
to the extent necessary in their respective businesses, all material 
trademarks, trade names, copyrights, patents, patent rights, computer 
software, licenses and other Intangible Assets that are used in the conduct 
of their businesses as now operated, and no such Intangible Asset, to the 
best knowledge of Borrowers, conflicts with the valid trademark, trade name, 
copyright, patent, patent right or Intangible Asset of any other Person to 
the extent that such conflict constitutes a Material Adverse Effect.


                                        -63-
<PAGE>

         4.9  PUBLIC UTILITY HOLDING COMPANY ACT.  None of Borrowers is a 
"holding company", or a "subsidiary company" of a "holding company", or an 
"affiliate" of a "holding company" or of a "subsidiary company" of a "holding 
company", within the meaning of the Public Utility Holding Company Act of 
1935, as amended.

         4.10  LITIGATION.  EXCEPT for (a) any matter fully covered as to 
subject matter and amount (subject to applicable deductibles and retentions) 
by insurance for which the insurance carrier has not asserted lack of subject 
matter coverage or reserved its right to do so, (b) any matter, or series of 
related matters, involving a claim against Parent or any of its Subsidiaries 
of less than $1,000,000, (c) matters of an administrative nature not 
involving a claim or charge against Parent or any of its Subsidiaries and (d) 
matters set forth in SCHEDULE 4.10, there are no actions, suits, proceedings 
or investigations pending as to which Parent or any of its Subsidiaries have 
been served or have received notice or, to the best knowledge of Borrowers, 
threatened against or affecting Parent or any of its Subsidiaries or any 
Property of any of them before any Governmental Agency.

         4.11  BINDING OBLIGATIONS.  Each of the Loan Documents to which 
Borrowers are a Party will, when executed and delivered by Borrowers, 
constitute the legal, valid and binding obligation of Borrowers, enforceable 
against Borrowers in accordance with its terms, EXCEPT as enforcement may be 
limited by Debtor Relief Laws or equitable principles relating to the 
granting of specific performance and other equitable remedies as a matter of 
judicial discretion.

         4.12  NO DEFAULT.  No event has occurred and is continuing that is a 
Default or Event of Default.

         4.13  ERISA.

               (a)  With respect to each Pension Plan:

                    (i)  such Pension Plan complies in all material respects 
         with ERISA and any other applicable Laws to the extent that 
         noncompliance could reasonably be expected to have a Material 
         Adverse Effect;

                   (ii)  such Pension Plan has not incurred any

         9.1  EVENTS OF DEFAULT.  The existence or occurrence of any one or

circumstances whatsoever, shall constitute an Event of Default:

                 (a)  Borrowers fail to pay any principal on any of the 
      Notes, or any portion thereof, on the date when due; or

                 (b)  Borrowers fail to pay any interest on any of the Notes, 
      or any fees under Sections 3.4 or 3.5, or any portion thereof, within

      fee or amount payable to the Banks under any Loan Document, or any 
      portion thereof, within five (5) Banking Days after demand therefor; or

                 (c)  Borrowers fail to comply with any of the covenants 
      contained in ARTICLE 6; or

                 (d)  Borrowers fail to comply with Section 7.1(k) in any 
      respect that is materially adverse to the interests of the Banks; or

                 (e)  Any Borrower or any other Party fails to perform or 
      observe any other covenant or agreement (not specified in clause (a), 
      (b), (c) or (d) above) contained in any Loan Document on its part to be 
      performed or observed within thirty (30) Banking Days after the giving 
      of notice by the Managing Agent on behalf of the Requisite Banks of 
      such Default or, if such Default is not reasonably susceptible of cure 
      within such period, within such longer period as is reasonably 
      necessary to effect a cure so long as such Borrower or such Party 
      continues to diligently pursue cure of such Default but not in any 
      event in excess of sixty (60) Banking Days; or

                 (f)  Any representation or warranty of Borrowers made in any 
      Loan Document, or in any certificate or other writing delivered by

      materially adverse to the 


                                      -81-
<PAGE>

      interests of the Banks; or

      principal installment, of any present or future Indebtedness (OTHER 
      THAN Non-Recourse Debt) of $5,000,000 or more, or any guaranty of 
      present or future Indebtedness (OTHER THAN Non-Recourse Debt) of 
      $5,000,000 or more, on its part to be paid, when due (or within any 
      stated grace period), whether at the stated maturity, upon 
      acceleration, by reason of required prepayment or otherwise or (ii) 
      fails to perform or observe any other term, covenant or agreement on 
      its part to be performed or observed, or suffers any event of default 
      to occur, in connection with any present or future Indebtedness (OTHER 
      THAN Non-Recourse Debt) of $5,000,000 or more, or of any guaranty of 
      present or future Indebtedness (OTHER THAN Non-Recourse Debt) of 
      $5,000,000 or more, if as a result of such failure or sufferance any 
      holder or holders thereof (or an agent or trustee on its or their 
      behalf) has the right to declare such Indebtedness due before the date 
      on which it otherwise would become due or the right to require 
      Borrowers to redeem or purchase, or offer to redeem or purchase, all or 
      any portion of such Indebtedness (PROVIDED, that for the purpose of 
      this clause (g), the principal amount of Indebtedness consisting of a 
      Swap Agreement shall be the amount which is then payable by the 
      counterparty to close out the Swap Agreement); or

      omission to act) of the Managing Agent or the Banks or satisfaction in 
      full of all the Obligations ceases to be in full force and effect or is 
      declared by a court of competent jurisdiction to be null and void, 
      invalid or unenforceable in any respect which is materially adverse to 
      the interests of the Banks; or any Party thereto denies in writing that 
      it has any or further liability or obligation under any Loan Document, 
      or purports to revoke, terminate or rescind same; or

                 (i)  A final judgment against any of Borrowers is entered 
      for the payment of money in excess of $1,000,000 (not covered by 
      insurance or for which an insurer has reserved its rights) and, absent 
      procurement of a stay of execution, such judgment remains unsatisfied 
      for thirty (30) calendar days after the date of entry of judgment, or 
      in any event later than five (5) days prior to the date of any proposed 
      sale thereunder; or any writ or warrant of attachment or execution or 
      similar process is issued or levied against all or any material part of 


                                     -82-
<PAGE>

      the Property of any such Person and is not released, vacated or fully 
      bonded within thirty (30) calendar days after its issue or levy; or

                 (j)  Any of Borrowers institutes or consents to the 
      institution of any proceeding under a Debtor Relief Law relating to it 
      or to all or any material part of its Property, or is unable or admits 
      in writing its inability to pay its debts as they mature, or makes an 
      assignment for the benefit of creditors; or applies for or consents to 
      the appointment of any receiver, trustee, custodian, conservator, 
      liquidator, rehabilitator or similar officer for it or for all or any 
      material part of its Property; or any receiver, trustee, custodian, 
      conservator, liquidator, rehabilitator or similar officer is appointed 
      without the application or consent of that Person and the appointment 
      continues undischarged or unstayed for sixty (60) calendar days; or any 
      proceeding under a Debtor Relief Law relating to any such Person or to 
      all or any part of its Property is instituted without the consent of 
      that Person and continues undismissed or unstayed for sixty (60) 
      calendar days; or

                 (k)  The occurrence of an Event of Default (as such term is 
      or may hereafter be specifically defined in any other Loan Document) 
      under any other Loan Document; or

                 (l)  Any Pension Plan maintained by Borrowers is determined 
      to have a material "accumulated funding deficiency" as that term is 
      defined in Section 302 of ERISA in excess of an amount equal to 5% of 
      the combined total assets of Borrowers as of the most-recently ended 
      Fiscal Quarter.

         9.2  REMEDIES UPON EVENT OF DEFAULT.  Without limiting any other 
rights or remedies of the Managing Agent or the Banks provided for elsewhere 
in this Agreement, or the other Loan Documents, or by applicable Law, or in 
equity, or otherwise:

                 (a)  Upon the occurrence, and during the continuance, of any 
      Event of Default OTHER THAN an Event of Default described in Section 
      9.1(j):

                      (1)  the Commitments to make Advances and all other 
             obligations of the Managing Agent or the Banks and all rights of 
             Borrowers and any other Parties under the Loan Documents shall 
             be 


                                      -83-
<PAGE>

             suspended without notice to or demand upon Borrowers, which are 
             expressly waived by Borrowers, EXCEPT that all of the Banks or 
             the Requisite Banks (as the case may be, in accordance with 
             Section 11.2) may waive an Event of Default or, without waiving, 
             determine, upon terms and conditions satisfactory to the Banks 
             or Requisite Banks, as the case may be, to reinstate the 
             Commitments and such other obligations and rights and make 
             further Advances, which waiver or determination shall apply 
             equally to, and shall be binding upon, all the Banks; and

                      (2)  the Requisite Banks may request the Managing Agent 
             to, and the Managing Agent thereupon shall, terminate the 
             Commitments and/or declare all or any part of the unpaid 
             principal of all Notes, all interest accrued and unpaid thereon 
             and all other amounts payable under the Loan Documents to be 
             forthwith due and payable, whereupon the same shall become and 
             be forthwith due and payable, without protest, presentment, 
             notice of dishonor, demand or further notice of any kind, all of 
             which are expressly waived by Borrowers.

                 (b)  Upon the occurrence of any Event of Default described 
      in Section 9.1(j):

                      (1)  the Commitments to make Advances and all other 
             obligations of the Managing Agent or the Banks and all rights of 
             Borrowers and any other Parties under the Loan Documents shall 
             terminate without notice to or demand upon Borrowers, which are 
             expressly waived by Borrowers, EXCEPT that all of the Banks may 
             waive the Event of Default or, without waiving, determine, upon 
             terms and conditions satisfactory to all the Banks, to reinstate 
             the Commitments and such other obligations and rights and make 
             further Advances, which determination shall apply equally to, 
             and shall be binding upon, all the Banks; and

                      (2)  the unpaid principal of all Notes, all interest 
             accrued and unpaid thereon and all other amounts payable under 
             the Loan Documents shall be forthwith due and payable, without 
             protest, presentment, notice of dishonor, demand or further 
             notice of any kind, all of which are expressly waived by 
             Borrowers.


                                      -84-
<PAGE>

                 (c)  Upon the occurrence of any Event of Default, the Banks 
      and the Managing Agent, or any of them, without notice to (EXCEPT as 
      expressly provided for in any Loan Document) or demand upon Borrowers, 
      which are expressly waived by Borrowers (EXCEPT as to notices expressly 
      provided for in any Loan Document), may proceed (but only with the 
      consent of the Requisite Banks) to protect, exercise and enforce their 
      rights and remedies under the Loan Documents against Borrowers and any 
      other Party and such other rights and remedies as are provided by Law 
      or equity.

                 (d)  The order and manner in which the Banks' rights and 
      remedies are to be exercised shall be determined by the Requisite Banks 
      in their sole discretion, and all payments received by the Managing 
      Agent and the Banks, or any of them, shall be applied first to the 
      costs and expenses (including reasonable attorneys' fees and 
      disbursements and the reasonably allocated costs of attorneys employed 
      by the Managing Agent or by any Bank) of the Managing Agent and of the 
      Banks, and thereafter paid pro rata to the Banks in the same 
      proportions that the aggregate Obligations owed to each Bank under the 
      Loan Documents bear to the aggregate Obligations owed under the Loan 
      Documents to all the Banks, without priority or preference among the 
      Banks.  Regardless of how each Bank may treat payments for the purpose 
      of its own accounting, for the purpose of computing Borrowers' 
      Obligations hereunder and under the Notes, payments shall be applied 
      FIRST, to the costs and expenses of the Managing Agent and the Banks, 
      as set forth above, SECOND, to the payment of accrued and unpaid 
      interest due under any Loan Documents to and including the date of such 
      application (ratably, and without duplication, according to the accrued 
      and unpaid interest due under each of the Loan Documents), and THIRD, 
      to the payment of all other amounts (including principal and fees) then 
      owing to the Managing Agent or the Banks under the Loan Documents.  No 
      application of payments will cure any Event of Default, or prevent 
      acceleration, or continued acceleration, of amounts payable under the 
      Loan Documents, or prevent the exercise, or continued exercise, of 
      rights or remedies of the Banks hereunder or thereunder or at Law or in 
      equity.

                                  Article 10
                              THE MANAGING AGENT


         10.1  APPOINTMENT AND AUTHORIZATION.  Subject to Section 10.8, each 
Bank hereby irrevocably appoints and authorizes the Managing Agent to take 
such action as agent on its behalf and to exercise such powers under the Loan 
Documents as are delegated to the Managing Agent by the terms thereof or are 
reasonably incidental, as determined by the Managing Agent, thereto.  This 
appointment and authorization is intended solely for the purpose of 
facilitating the servicing of the Loans and does not constitute appointment 
of the Managing Agent as trustee for any Bank or as representative of any 
Bank for any other purpose and, EXCEPT as specifically set forth in the Loan 
Documents to the contrary, the Managing Agent shall take such action and 
exercise such powers only in an administrative and ministerial capacity.

         10.2  MANAGING AGENT AND AFFILIATES.  Bank of America National Trust 
and Savings Association (and each successor Managing Agent) has the same 
rights and powers under the Loan Documents as any other Bank and may exercise 
the same as though it were not the Managing Agent, and the term "Bank" or 
"Banks" includes Bank of America National Trust and Savings Association in 
its individual capacity.  Bank of America National Trust and Savings 
Association (and each successor Managing Agent) and its Affiliates may accept 
deposits from, lend money to and generally engage in any kind of banking, 
trust or other business with Borrowers, any Subsidiary thereof, or any 
Affiliate of Borrowers or any Subsidiary thereof, as if it were not the 
Managing Agent and without any duty to account therefor to the Banks.  Bank 
of America National Trust and Savings Association (and each successor 
Managing Agent) need not account to any other Bank for any monies received by 
it for reimbursement of its costs and expenses as Managing Agent hereunder, 
or for any monies received by it in its capacity as a Bank hereunder. The 
Managing Agent shall not be deemed to hold a fiduciary relationship with any 
Bank and no implied covenants, functions, responsibilities, duties, 
obligations or liabilities shall be read into this Agreement or otherwise 
exist against the Managing Agent.

         10.3  PROPORTIONATE INTEREST IN ANY COLLATERAL.  The Managing Agent, 
on behalf of all the Banks, shall hold in accordance with the Loan Documents 
all items of any collateral or interests therein received or held by the 
Managing Agent. Subject to the Managing Agent's and the Banks' rights to 
reimbursement for their costs and 


                                     -86-
<PAGE>

expenses hereunder (INCLUDING reasonable attorneys' fees and disbursements 
and other professional services and the reasonably allocated costs of 
attorneys employed by the Managing Agent or a Bank) and subject to the 
application of payments in accordance with Section 9.2(d), each Bank shall 
have an interest in the Banks' interest in such collateral or interests 
therein in the same proportions that the aggregate Obligations owed such Bank 
under the Loan Documents bear to the aggregate Obligations owed under the 
Loan Documents to all the Banks, without priority or preference among the 
Banks.

         10.4  BANKS' CREDIT DECISIONS.  Each Bank agrees that it has, 
independently and without reliance upon the Managing Agent, any other Bank or 
the directors, officers, agents, employees or attorneys of the Managing Agent 
or of any other Bank, and instead in reliance upon information supplied to it 
by or on behalf of Borrowers and upon such other information as it has deemed 
appropriate, made its own independent credit analysis and decision to enter 
into this Agreement.  Each Bank also agrees that it shall, independently and 
without reliance upon the Managing Agent, any other Bank or the directors, 
officers, agents, employees or attorneys of the Managing Agent or of any 
other Bank, continue to make its own independent credit analyses and 
decisions in acting or not acting under the Loan Documents.

         10.5  ACTION BY MANAGING AGENT.

                 (a)  Absent actual knowledge of the Managing Agent of the 
      existence of a Default, the Managing Agent may assume that no Default 
      has occurred and is continuing, unless the Managing Agent (or the Bank 
      that is then the Managing Agent) has received notice from Borrowers 
      stating the nature of the Default or has received notice from a Bank 
      stating the nature of the Default and that such Bank considers the 
      Default to have occurred and to be continuing.

                 (b)  The Managing Agent has only those obligations under the 
      Loan Documents as are expressly set forth therein.

                 (c)  EXCEPT for any obligation expressly set forth in the 
      Loan Documents and as long as the Managing Agent may assume that no 
      Event of Default has occurred and is continuing, the Managing Agent 
      may, but shall not be required to, exercise its discretion to act or 
      not act, EXCEPT that the Managing Agent shall be required to act or not 
      act upon the instructions of the Requisite 


                                      -87-

<PAGE>

      Banks (or of all the Banks, to the extent required by Section 11.2) and 
      those instructions shall be binding upon the Managing Agent and all the 
      Banks, PROVIDED that the Managing Agent shall not be required to act or 
      not act if to do so would be contrary to any Loan Document or to 
      applicable Law or would result, in the reasonable judgment of the 
      Managing Agent, in substantial risk of liability to the Managing Agent.

                 (d)  If the Managing Agent has received a notice specified 
      in clause (a), the Managing Agent shall immediately give notice thereof 
      to the Banks and shall act or not act upon the instructions of the 
      Requisite Banks (or of all the Banks, to the extent required by Section 
      11.2), PROVIDED that the Managing Agent shall not be required to act or 
      not act if to do so would be contrary to any Loan Document or to 
      applicable Law or would result, in the reasonable judgment of the 
      Managing Agent, in substantial risk of liability to the Managing Agent, 
      and EXCEPT that if the Requisite Banks (or all the Banks, if required 
      under Section 11.2) fail, for five (5) Banking Days after the receipt 
      of notice from the Managing Agent, to instruct the Managing Agent, then 
      the Managing Agent, in its sole discretion, may act or not act as it 
      deems advisable for the protection of the interests of the Banks.

                 (e)  The Managing Agent shall have no liability to any Bank 
      for acting, or not acting, as instructed by the Requisite Banks (or all 
      the Banks, if required under Section 11.2), notwithstanding any other 
      provision hereof.

         10.6  LIABILITY OF MANAGING AGENT.  Neither the Managing Agent nor 
any of its directors, officers, agents, employees or attorneys shall be 
liable for any action taken or not taken by them under or in connection with 
the Loan Documents, EXCEPT for their own gross negligence or willful 
misconduct.  Without limitation on the foregoing, the Managing Agent and its 
directors, officers, agents, employees and attorneys:

                 (a)  May treat the payee of any Note as the holder thereof 
      until the Managing Agent receives notice of the assignment or transfer 
      thereof, in form satisfactory to the Managing Agent, signed by the 
      payee, and may treat each Bank as the owner of that Bank's interest in 
      the Obligations for all purposes of this Agreement until the Managing 
      Agent receives notice of the assignment or transfer thereof, in form 
      satisfactory to the Managing Agent, 


                                      -88-
<PAGE>

      signed by that Bank;

                 (b)  May consult with legal counsel (INCLUDING in-house 
      legal counsel), accountants (INCLUDING in-house accountants) and other 
      professionals or experts selected by it, or with legal counsel, 
      accountants or other professionals or experts for Borrowers and/or 
      their Subsidiaries or the Banks, and shall not be liable for any action 
      taken or not taken by it in good faith in accordance with any advice of 
      such legal counsel, accountants or other professionals or experts;

                 (c)  Shall not be responsible to any Bank for any statement, 
      warranty or representation made in any of the Loan Documents or in any 
      notice, certificate, report, request or other statement (written or 
      oral) given or made in connection with any of the Loan Documents;

                 (d)  EXCEPT to the extent expressly set forth in the Loan 
      Documents, shall have no duty to ask or inquire as to the performance 
      or observance by Borrowers or its Subsidiaries of any of the terms, 
      conditions or covenants of any of the Loan Documents or to inspect any 
      collateral or any Property, books or records of Borrowers or their 
      Subsidiaries;

                 (e)  Will not be responsible to any Bank for the due 
      execution, legality, validity, enforceability, genuineness, 
      effectiveness, sufficiency or value of any Loan Document, any other 
      instrument or writing furnished pursuant thereto or in connection 
      therewith, or any collateral;

                 (f)  Will not incur any liability by acting or not acting in 
      reliance upon any Loan Document, notice, consent, certificate, 
      statement, request or other instrument or writing believed in good 
      faith by it to be genuine and signed or sent by the proper party or 
      parties; and

                 (g)  Will not incur any liability for any arithmetical error 
      in computing any amount paid or payable by the Borrowers or any 
      Subsidiary or Affiliate thereof or paid or payable to or received or 
      receivable from any Bank under any Loan Document, INCLUDING, without 
      limitation, principal, interest, commitment fees, Advances and other 
      amounts; PROVIDED that, promptly upon discovery of such an error in 
      computation, the Managing Agent, the Banks and 


                                     -89-
<PAGE>

      (to the extent applicable) Borrowers and/or their Subsidiaries or 
      Affiliates shall make such adjustments as are necessary to correct such
      error and to restore the parties to the position that they would have 
      occupied had the error not occurred.

         10.7  INDEMNIFICATION.  Each Bank shall, ratably in accordance with 
its Pro Rata Share of the Commitments (if the Commitments are then in effect) 
or in accordance with its proportion of the aggregate Indebtedness then 
evidenced by the Notes (if the Commitments have then been terminated), 
indemnify and hold the Managing Agent and its directors, officers, agents, 
employees and attorneys harmless against any and all liabilities, 
obligations, losses, damages, penalties, actions, judgments, suits, costs, 
expenses or disbursements of any kind or nature whatsoever (INCLUDING 
reasonable attorneys' fees and disbursements and allocated costs of attorneys 
employed by the Managing Agent) that may be imposed on, incurred by or 
asserted against it or them in any way relating to or arising out of the Loan 
Documents (other than losses incurred by reason of the failure of Borrowers 
to pay the Indebtedness represented by the Notes) or any action taken or not 
taken by it as Managing Agent thereunder, EXCEPT such as result from its own 
gross negligence or willful misconduct. Without limitation on the foregoing, 
each Bank shall reimburse the Managing Agent upon demand for that Bank's Pro 
Rata Share of any out-of-pocket cost or expense incurred by the Managing 
Agent in connection with the negotiation, preparation, execution, delivery, 
amendment, waiver, restructuring, reorganization (INCLUDING a bankruptcy 
reorganization), enforcement or attempted enforcement of the Loan Documents, 
to the extent that any Borrower or any other Party is required by Section 
11.3 to pay that cost or expense but fails to do so upon demand.  Nothing in 
this Section 10.7 shall entitle the Managing Agent or any indemnitee referred 
to above to recover any amount from the Banks if and to the extent that such 
amount has theretofore been recovered from Borrowers or any of their 
Subsidiaries.  To the extent that the Managing Agent or any indemnitee 
referred to above is later reimbursed such amount by Borrowers or any of its 
Subsidiaries, it shall return the amounts paid to it by the Banks in respect 
of such amount.

         10.8  SUCCESSOR MANAGING AGENT.  The Managing Agent may, and at the 
request of the Requisite Banks shall, resign as Managing Agent upon 
reasonable notice to the Banks and Borrowers effective upon acceptance of 
appointment by a successor Managing Agent.  If the Managing Agent shall 
resign as Managing Agent under this Agreement, the Requisite Banks shall 
appoint from among the Banks a successor Managing Agent for the Banks, which 
successor Managing Agent shall be approved by 


                                      -90-
<PAGE>

Borrowers (and such approval shall not be unreasonably withheld or delayed). 
If no successor Managing Agent is appointed prior to the effective date of 
the resignation of the Managing Agent, the Managing Agent may appoint, after 
consulting with the Banks and the Borrowers, a successor Managing Agent from 
among the Banks.  Upon the acceptance of its appointment as successor 
Managing Agent hereunder, such successor Managing Agent shall succeed to all 
the rights, powers and duties of the retiring Managing Agent and the term 
"Managing Agent" shall mean such successor Managing Agent and the retiring 
Managing Agent's appointment, powers and duties as Managing Agent shall be 
terminated.  After any retiring Managing Agent's resignation hereunder as 
Managing Agent, the provisions of this ARTICLE 10, and Sections 11.3, 11.11 
and 11.22, shall inure to its benefit as to any actions taken or omitted to 
be taken by it while it was Managing Agent under this Agreement.  
Notwithstanding the foregoing, if (a) the Managing Agent has not been paid 
its agency fees under Section 3.5 or has not been reimbursed for any expense 
reimbursable to it under Section 11.3, in either case for a period of at 
least one (1) year and (b) no successor Managing Agent has accepted 
appointment as Managing Agent by the date which is thirty (30) days following 
a retiring Managing Agent's notice of resignation, the retiring Managing 
Agent's resignation shall nevertheless thereupon become effective and the 
Banks shall perform all of the duties of the Managing Agent hereunder until 
such time, if any, as the Requisite Banks appoint a successor Managing Agent 
as provided for above.

         10.9  NO OBLIGATIONS OF BORROWERS.  Nothing contained in this 
Article 10 shall be deemed to impose upon Borrowers any obligation in respect 
of the due and punctual performance by the Managing Agent of its obligations 
to the Banks under any provision of this Agreement, and Borrowers shall have 
no liability to the Managing Agent or any of the Banks in respect of any 
failure by the Managing Agent or any Bank to perform any of its obligations 
to the Managing Agent or the Banks under this Agreement.  Without limiting 
the generality of the foregoing, where any provision of this Agreement 
relating to the payment of any amounts due and owing under the Loan Documents 
provides that such payments shall be made by Borrowers to the Managing Agent 
for the account of the Banks, Borrowers' obligations to the Banks in respect 
of such payments shall be deemed to be satisfied upon the making of such 
payments to the Managing Agent in the manner provided by this Agreement.

                                MISCELLANEOUS


         11.1  CUMULATIVE REMEDIES; NO WAIVER.  The rights, powers, 
privileges and remedies of the Managing Agent and the Banks provided herein 
or in any Note or other Loan Document are cumulative and not exclusive of any 
right, power, privilege or remedy provided by Law or equity.  No failure or 
delay on the part of the Managing Agent or any Bank in exercising any right, 
power, privilege or remedy may be, or may be deemed to be, a waiver thereof; 
nor may any single or partial exercise of any right, power, privilege or 
remedy preclude any other or further exercise of the same or any other right, 
power, privilege or remedy. The terms and conditions of ARTICLE 8 hereof are 
inserted for the sole benefit of the Managing Agent and the Banks; the same 
may be waived in whole or in part, with or without terms or conditions, in 
respect of any Loan without prejudicing the Managing Agent's or the Banks' 
rights to assert them in whole or in part in respect of any other Loan.

         11.2  AMENDMENTS; CONSENTS.  No amendment, modification, supplement, 
extension, termination or waiver of any provision of this Agreement or any 
other Loan Document, no approval or consent thereunder, and no consent to any 
departure by Borrowers or any other Party therefrom, may in any event be 
effective unless in writing signed by the Requisite Banks (and, in the case 
of any amendment, modification or supplement of or to any Loan Document to 
which any of Borrowers is a Party, signed by each such Party, and, in the 
case of any amendment, modification or supplement to ARTICLE 10, signed by 
the Managing Agent), and then only in the specific instance and for the 
specific purpose given; and, without the approval in writing of all the 
Banks, no amendment, modification, supplement, termination, waiver or consent 
may be effective:

                 (a)  To amend or modify the principal of, or the amount of 
      principal, principal prepayments or the rate of interest payable on, 
      any Note, or the amount of the Commitments or the Pro Rata Share of any 
      Bank or the amount of any commitment fee payable to any Bank, or any 
      other fee or amount payable to any Bank under the Loan Documents or to 
      waive an Event of Default consisting of the failure of Borrowers to pay 
      when due principal, interest or any fee;


                                      -92-
<PAGE>

                 (b)  To postpone any date fixed for any payment of principal 
      of, prepayment of principal of or any installment of interest on, any 
      Note or any installment of any fee, or to extend the term of the 
      Commitments;

                 (c)  To amend the provisions of the definition of "REQUISITE 
      BANKS" or "MATURITY DATE"; or

                 (d)  To amend or waive ARTICLE 8 or this Section 11.2; or

                 (e)  To amend any provision of this Agreement that expressly 
      requires the consent or approval of all the Banks.

Any amendment, modification, supplement, termination, waiver or consent 
pursuant to this Section 11.2 shall apply equally to, and shall be binding 
upon, all the Banks and the Managing Agent.

         11.3  COSTS, EXPENSES AND TAXES.  Borrowers shall pay within five 
(5) Banking Days after demand, accompanied by an invoice therefor, the 
reasonable costs and expenses of the Managing Agent in connection with the 
negotiation, preparation, syndication, execution and delivery of the Loan 
Documents (subject to the ceiling contained in a letter agreement between 
Parent and the Managing Agent) and any amendment thereto or waiver thereof.  
Borrowers shall also pay on demand, accompanied by an invoice therefor, the 
reasonable costs and expenses of the Managing Agent and the Banks in 
connection with the refinancing, restructuring, reorganization (INCLUDING a 
bankruptcy reorganization) and enforcement or attempted enforcement of the 
Loan Documents, and any matter related thereto.  The foregoing costs and 
expenses shall include filing fees, recording fees, title insurance fees, 
appraisal fees, search fees, and other out-of-pocket expenses and the 
reasonable fees and out-of-pocket expenses of any legal counsel (INCLUDING 
reasonably allocated costs of legal counsel employed by the Managing Agent or 
any Bank), independent public accountants and other outside experts retained 
by the Managing Agent or any Bank, whether or not such costs and expenses are 
incurred or suffered by the Managing Agent or any Bank in connection with or 
during the course of any bankruptcy or insolvency proceedings of any of 
Borrowers or any Subsidiary thereof.  Borrowers shall pay any and all 
documentary and other taxes, EXCLUDING (i) taxes imposed on or measured in 
whole or in part by its overall net income imposed on it by (A) any 
jurisdiction (or political subdivision thereof) in which it is organized or 
maintains its principal office 


                                     -93-
<PAGE>

or Eurodollar Lending Office or (B) any jurisdiction (or political 
subdivision thereof) in which it is "doing business" or (ii) any withholding 
taxes or other taxes based on gross income imposed by the United States of 
America for any period with respect to which it has failed to provide 
Borrowers with the appropriate form or forms required by Section 11.21, to 
the extent such forms are then required by applicable Laws, and all costs, 
expenses, fees and charges payable or determined to be payable in connection 
with the filing or recording of this Agreement, any other Loan Document or 
any other instrument or writing to be delivered hereunder or thereunder, or 
in connection with any transaction pursuant hereto or thereto, and shall 
reimburse, hold harmless and indemnify on the terms set forth in 11.11 the 
Managing Agent and the Banks from and against any and all loss, liability or 
legal or other expense with respect to or resulting from any delay in paying 
or failure to pay any such tax, cost, expense, fee or charge or that any of 
them may suffer or incur by reason of the failure of any Party to perform any 
of its Obligations.  Any amount payable to the Managing Agent or any Bank 
under this Section 11.3 shall bear interest from the fifth Banking Day 
following the date of demand for payment at the Default Rate.

         11.4  NATURE OF BANKS' OBLIGATIONS.  The obligations of the Banks 
hereunder are several and not joint or joint and several.  Nothing contained 
in this Agreement or any other Loan Document and no action taken by the 
Managing Agent or the Banks or any of them pursuant hereto or thereto may, or 
may be deemed to, make the Banks a partnership, an association, a joint 
venture or other entity, either among themselves or with the Borrowers or any 
Affiliate of any of Borrowers.  A default by any Bank will not increase the 
Pro Rata Share of the Commitments attributable to any other Bank.  Any Bank 
not in default may, if it desires, assume in such proportion as the 
nondefaulting Banks agree the obligations of any Bank in default, but is not 
obligated to do so.  The Managing Agent agrees that it will use its best 
efforts either to induce the other Banks to assume the obligations of a Bank 
in default or to obtain another Bank, reasonably satisfactory to Borrowers, 
to replace such a Bank in default.

         11.5  SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  All 
representations and warranties contained herein or in any other Loan 
Document, or in any certificate or other writing delivered by or on behalf of 
any one or more of the Parties to any Loan Document, will survive the making 
of the Loans hereunder and the execution and delivery of the Notes, and have 
been or will be relied upon by the Managing Agent and each Bank, 
notwithstanding any investigation made by the Managing Agent or any 


                                      -94-

<PAGE>

Bank or on their behalf.

         11.6  NOTICES.  EXCEPT as otherwise expressly provided in the Loan 
Documents, all notices, requests, demands, directions and other 
communications provided for hereunder or under any other Loan Document must 
be in writing and must be mailed, telegraphed, telecopied, dispatched by 
commercial courier or delivered to the appropriate party at the address set 
forth on the signature pages of this Agreement or other applicable Loan 
Document or, as to any party to any Loan Document, at any other address as 
may be designated by it in a written notice sent to all other parties to such 
Loan Document in accordance with this Section.  EXCEPT as otherwise expressly 
provided in any Loan Document, if any notice, request, demand, direction or 
other communication required or permitted by any Loan Document is given by 
mail it will be effective on the earlier of receipt or the fourth Banking Day 
after deposit in the United States mail with first class or airmail postage 
prepaid; if given by telegraph or cable, when delivered to the telegraph 
company with charges prepaid; if given by telecopier, when sent; if 
dispatched by commercial courier, on the scheduled delivery date; or if given 
by personal delivery, when delivered.

         11.7  EXECUTION OF LOAN DOCUMENTS.  Unless the Managing Agent 
otherwise specifies with respect to any Loan Document, (a) this Agreement and 
any other Loan Document may be executed in any number of counterparts and any 
party hereto or thereto may execute any counterpart, each of which when 
executed and delivered will be deemed to be an original and all of which 
counterparts of this Agreement or any other Loan Document, as the case may 
be, when taken together will be deemed to be but one and the same instrument 
and (b) execution of any such counterpart may be evidenced by a telecopier 
transmission of the signature of such party.  The execution of this Agreement 
or any other Loan Document by any party hereto or thereto will not become 
effective until counterparts hereof or thereof, as the case may be, have been 
executed by all the parties hereto or thereto.

         11.8  BINDING EFFECT; ASSIGNMENT.

                 (a)  This Agreement and the other Loan Documents to which 
      Borrowers are a Party will be binding upon and inure to the benefit of 
      Borrowers, the Managing Agent, each of the Banks, and their respective 
      successors and assigns, EXCEPT that Borrowers may not assign their 
      rights hereunder or thereunder or any interest herein or therein 
      without the prior 


                                      -95-
<PAGE>

      written consent of all the Banks.  Each Bank represents that it is not 
      acquiring its Note with a view to the distribution thereof within the 
      meaning of the Securities Act of 1933, as amended (subject to any 
      requirement that disposition of such Note must be within the control of 
      such Bank).  Any Bank may at any time pledge its Note or any other 
      instrument evidencing its rights as a Bank under this Agreement to a 
      Federal Reserve Bank, but no such pledge shall release that Bank from 
      its obligations hereunder or grant to such Federal Reserve Bank the 
      rights of a Bank hereunder absent foreclosure of such pledge.

                 (b)  From time to time following the Closing Date, each Bank 
      may assign to one or more Eligible Assignees all or any portion of its 
      Pro Rata Share of the Commitments; PROVIDED that (i) such Eligible 
      Assignee, if not then a Bank or an Affiliate of the assigning Bank, 
      shall be approved by the Managing Agent and (if no Event of Default 
      then exists) Borrowers (neither of which approvals shall be 
      unreasonably withheld or delayed), (ii) such assignment shall be 
      evidenced by a Commitments Assignment and Acceptance, a copy of which 
      shall be furnished to the Managing Agent as hereinbelow provided, (iii) 
      EXCEPT in the case of an assignment to an Affiliate of the assigning 
      Bank, to another Bank or of the entire remaining Commitments of the 
      assigning Bank, the assignment shall not assign a Pro Rata Share of the 
      Commitments that is equivalent to less than $10,000,000, (iv) the 
      assignment shall assign the same Pro Rata Share of the Line A 
      Commitment and the Line B Commitment and (v) the effective date of any 
      such assignment shall be as specified in the Commitments Assignment and 
      Acceptance, but not earlier than the date which is five (5) Banking 
      Days after the date the Managing Agent has received the Commitments 
      Assignment and Acceptance.  Upon the effective date of such Commitments 
      Assignment and Acceptance, the Eligible Assignee named therein shall be 
      a Bank for all purposes of this Agreement, with the Pro Rata Share of 
      the Commitments therein set forth and, to the extent of such Pro Rata 
      Share, the assigning Bank shall be released from its further 
      obligations under this Agreement.  Borrowers agree that they shall 
      execute and deliver (against delivery by the assigning Bank to 
      Borrowers of its Note) to such assignee Bank, Notes evidencing that 
      assignee Bank's Pro Rata Share of the Commitments, and to the assigning 
      Bank, Notes evidencing the remaining balance Pro Rata Share retained by 
      the assigning Bank.

                 (c)  By executing and delivering a Commitments Assignment 


                                      -96-
<PAGE>

      and Acceptance, the Eligible Assignee thereunder acknowledges and 
      agrees that: (i) other than the representation and warranty that it is 
      the legal and beneficial owner of the Pro Rata Share of the Commitments 
      being assigned thereby free and clear of any adverse claim, the 
      assigning Bank has made no representation or warranty and assumes no 
      responsibility with respect to any statements, warranties or 
      representations made in or in connection with this Agreement or the 
      execution, legality, validity, enforceability, genuineness or 
      sufficiency of this Agreement or any other Loan Document; (ii) the 
      assigning Bank has made no representation or warranty and assumes no 
      responsibility with respect to the financial condition of Borrowers or 
      the performance by Borrowers of the Obligations; (iii) it has received 
      a copy of this Agreement, together with copies of the most recent 
      financial statements delivered pursuant to Section 7.1 and such other 
      documents and information as it has deemed appropriate to make its own 
      credit analysis and decision to enter into such Commitments Assignment 
      and Acceptance; (iv) it will, independently and without reliance upon 
      the Managing Agent or any Bank and based on such documents and 
      information as it shall deem appropriate at the time, continue to make 
      its own credit decisions in taking or not taking action under this 
      Agreement; (v) it appoints and authorizes the Managing Agent to take 
      such action and to exercise such powers under this Agreement as are 
      delegated to the Managing Agent by this Agreement; and (vi) it will 
      perform in accordance with their terms all of the obligations which by 
      the terms of this Agreement are required to be performed by it as a 
      Bank.

                 (d)  The Managing Agent shall maintain at the Managing 
      Agent's Office a copy of each Commitments Assignment and Acceptance 
      delivered to it and a register (the "Register") of the names and 
      address of each of the Banks and the Pro Rata Share of the Commitments 
      held by each Bank, giving effect to each Commitments Assignment and 
      Acceptance.  The Register shall be available during normal business 
      hours for inspection by Borrowers or any Bank upon reasonable prior 
      notice to the Managing Agent.  After receipt of a completed Commitments 
      Assignment and Acceptance executed by any Bank and an Eligible 
      Assignee, and receipt of an assignment fee of $2,500 from such Bank or 
      Eligible Assignee, the Managing Agent shall, promptly following the 
      effective date thereof, provide to Borrowers and the Banks a revised 
      SCHEDULE 1.1 giving effect thereto. Borrowers, the Managing Agent and 
      the Banks shall deem and treat the Persons listed as Banks in the 
      Register as the

      holders and owners of the Pro Rata Share of the Commitments listed 
      therein for all purposes hereof, and no assignment or transfer of any 
      such Pro Rata Share of the Commitments shall be effective, in each case 
      unless and until a Commitments Assignment and Acceptance effecting the 
      assignment or transfer thereof shall have been accepted by the Managing 
      Agent and recorded in the Register as provided above.  Prior to such 
      recordation, all amounts owed with respect to the applicable Pro Rata 
      Share of the Commitments shall be owed to the Bank listed in the 
      Register as the owner thereof, and any request, authority or consent of 
      any Person who, at the time of making such request or giving such 
      authority or consent, is listed in the Register as a Bank shall be 
      conclusive and binding on any subsequent holder, assignee or transferee 
      of the corresponding Pro Rata Share of the Commitments.

                 (e)  Each Bank may from time to time grant participations to 
      one or more banks or other financial institutions (INCLUDING another 
      Bank but EXCLUDING an Employee Plan) in a portion of its Pro Rata Share 
      of the Commitments; PROVIDED, HOWEVER, that (i) such Bank's obligations 
      under this Agreement shall remain unchanged, (ii) such Bank shall 
      remain solely responsible to the other parties hereto for the 
      performance of such obligations, (iii) the participating banks or other 
      financial institutions shall not be a Bank hereunder for any purpose 
      EXCEPT, if the participation agreement so provides, for the purposes of 
      Sections 3.7, 3.8, 11.11 and 11.22 but only to the extent that the cost 
      of such benefits to Borrowers does not exceed the cost which Borrowers 
      would have incurred in respect of such Bank absent the participation, 
      (iv) Borrowers, the Managing Agent and the other Banks shall continue 
      to deal solely and directly with such Bank in connection with such 
      Bank's rights and obligations under this Agreement, (v) the 
      participation interest shall be expressed as a percentage of the 
      granting Bank's Pro Rata Share of the Commitments as it then exists and 
      shall not restrict an increase in the Commitments, or in the granting 
      Bank's Pro Rata Share of the Commitments, so long as the amount of the 
      participation interest is not affected thereby and (vi) the consent of 
      the holder of such participation interest shall not be required for 
      amendments or waivers of provisions of the Loan Documents OTHER THAN 
      those which (A) extend any Amortization Date, the Maturity Date or any 
      other date upon which any payment of money is due to the Banks, or (B) 
      reduce the rate of interest on the Notes, any fee or any other monetary 
      amount payable to the Banks or (C) reduce the amount of any installment 
      of principal due under 


                                      -98-
<PAGE>

         the Notes.

         11.9  RIGHT OF SETOFF.  If an Event of Default has occurred and is 
continuing, the Managing Agent or any Bank (but in each case only with the 
consent of the Requisite Banks) may exercise its rights under Article 9 of 
the Uniform Commercial Code and other applicable Laws and, to the extent 
permitted by applicable Laws, apply any funds in any deposit account 
maintained with it by Borrowers and/or any Property of Borrowers in its 
possession against the Obligations.

         11.10  SHARING OF SETOFFS.  Each Bank severally agrees that if it, 
through the exercise of any right of setoff, banker's lien or counterclaim 
against Borrowers, or otherwise, receives payment of the Obligations held by 
it that is ratably more than any other Bank, through any means, receives in 
payment of the Obligations held by that Bank, then, subject to applicable 
Laws:  (a) the Bank exercising the right of setoff, banker's lien or 
counterclaim or otherwise receiving such payment shall purchase, and shall be 
deemed to have simultaneously purchased, from each of the other Banks a 
participation in the Obligations held by the other Banks and shall pay to the 
other Banks a purchase price in an amount so that the share of the 
Obligations held by each Bank after the exercise of the right of setoff, 
banker's lien or counterclaim or receipt of payment shall be in the same 
proportion that existed prior to the exercise of the right of setoff, 
banker's lien or counterclaim or receipt of payment; and (b) such other 
adjustments and purchases of participations shall be made from time to time 
as shall be equitable to ensure that all of the Banks share any payment 
obtained in respect of the Obligations ratably in accordance with each Bank's 
share of the Obligations immediately prior to, and without taking into 
account, the payment; PROVIDED that, if all or any portion of a 
disproportionate payment obtained as a result of the exercise of the right of 
setoff, banker's lien, counterclaim or otherwise is thereafter recovered from 
the purchasing Bank by Borrowers or any Person claiming through or succeeding 
to the rights of Borrowers, the purchase of a participation shall be 
rescinded and the purchase price thereof shall be restored to the extent of 
the recovery, but without interest.  Each Bank that purchases a participation 
in the Obligations pursuant to this Section 11.10 shall from and after the 
purchase have the right to give all notices, requests, demands, directions 
and other communications under this Agreement with respect to the portion of 
the Obligations purchased to the same extent as though the purchasing Bank 
were the original owner of the Obligations purchased.  Borrowers expressly 
consent to the foregoing arrangements and agree that any Bank holding a 
participation in an Obligation so purchased pursuant to this Section 11.10 
may exercise any and all rights of 


                                      -99-
<PAGE>

setoff, banker's lien or counterclaim with respect to the participation as 
fully as if the Bank were the original owner of the Obligation purchased.

         11.11  INDEMNITY BY BORROWERS.  Borrowers agree to indemnify, save 
and hold harmless the Managing Agent and each Bank and their respective 
directors, officers, agents, attorneys and employees (collectively the 
"INDEMNITEES") from and against:  (a) any and all claims, demands, actions or 
causes of action (EXCEPT a claim, demand, action, or cause of action for any 
amount excluded from the definition of "Taxes" in Section 3.12(d)) if the 
claim, demand, action or cause of action arises out of or relates to any act 
or omission (or alleged act or omission) of Borrowers, their Affiliates or 
any of their officers, directors or stockholders relating to the Commitments, 
the use or contemplated use of proceeds of any Loan, or the relationship of 
Borrowers and the Banks under this Agreement; (b) any administrative or 
investigative proceeding by any Governmental Agency arising out of or related 
to a claim, demand, action or cause of action described in clause (a) above; 
and (c) any and all liabilities, losses, costs or expenses (INCLUDING 
reasonable attorneys' fees and the reasonably allocated costs of attorneys 
employed by any Indemnitee and disbursements of such attorneys and other 
professional services) that any Indemnitee suffers or incurs as a result of 
the assertion of any foregoing claim, demand, action or cause of action; 
PROVIDED that no Indemnitee shall be entitled to indemnification for any loss 
caused by its own gross negligence or willful misconduct or for any loss 
asserted against it by another Indemnitee. If any claim, demand, action or 
cause of action is asserted against any Indemnitee, such Indemnitee shall 
promptly notify Borrowers, but the failure to so promptly notify Borrowers 
shall not affect Borrowers' obligations under this Section unless such 
failure materially prejudices Borrowers' right to participate in the contest 
of such claim, demand, action or cause of action, as hereinafter provided.  
Such Indemnitee may (and shall, if requested by Borrowers in writing) contest 
the validity, applicability and amount of such claim, demand, action or cause 
of action and shall permit Borrowers to participate in such contest.  Any 
Indemnitee that proposes to settle or compromise any claim or proceeding for 
which Borrowers may be liable for payment of indemnity hereunder shall give 
Borrowers written notice of the terms of such proposed settlement or 
compromise reasonably in advance of settling or compromising such claim or 
proceeding and shall obtain Borrowers' prior consent (which shall not be 
unreasonably withheld or delayed).  In connection with any claim, demand, 
action or cause of action covered by this Section 11.11 against more than one 
Indemnitee, all such Indemnitees shall be represented by the same legal 
counsel (which may be a law firm engaged by the Indemnitees or attorneys 
employed by an 


                                      -100-
<PAGE>

Indemnitee or a combination of the foregoing) selected by the Indemnitees and 
reasonably acceptable to Borrowers; PROVIDED, that if such legal counsel 
determines in good faith that representing all such Indemnitees would or 
could result in a conflict of interest under Laws or ethical principles 
applicable to such legal counsel or that a defense or counterclaim is 
available to an Indemnitee that is not available to all such Indemnitees, 
then to the extent reasonably necessary to avoid such a conflict of interest 
or to permit unqualified assertion of such a defense or counterclaim, each 
affected Indemnitee shall be entitled to separate representation by legal 
counsel selected by that Indemnitee and reasonably acceptable to Borrowers, 
with all such legal counsel using reasonable efforts to avoid unnecessary 
duplication of effort by counsel for all Indemnitees; and FURTHER PROVIDED 
that the Managing Agent (as an Indemnitee) shall at all times be entitled to 
representation by separate legal counsel (which may be a law firm or 
attorneys employed by the Managing Agent or a combination of the foregoing).  
Any obligation or liability of Borrowers to any Indemnitee under this Section 
11.11 shall survive the expiration or termination of this Agreement and the 
repayment of all Loans and the payment and performance of all other 
Obligations owed to the Banks.

         11.12  NONLIABILITY OF THE BANKS.  Borrowers acknowledge and agree 
that:

                 (a)  Any inspections of any Property of Borrowers made by or 
      through the Managing Agent or the Banks are for purposes of 
      administration of the Loan only and Borrowers are not entitled to rely 
      upon the same (whether or not such inspections are at the expense of 
      Borrowers);

                 (b)  By accepting or approving anything required to be 
      observed, performed, fulfilled or given to the Managing Agent or the 
      Banks pursuant to the Loan Documents, neither the Managing Agent nor 
      the Banks shall be deemed to have warranted or represented the 
      sufficiency, legality, effectiveness or legal effect of the same, or of 
      any term, provision or condition thereof, and such acceptance or 
      approval thereof shall not constitute a warranty or representation to 
      anyone with respect thereto by the Managing Agent or the Banks;

                 (c)  The relationship between Borrowers and the Managing 
      Agent and the Banks is, and shall at all times remain, solely that of 
      borrowers and lenders; neither the Managing Agent nor the Banks shall 
      under any 


                                      -101-

<PAGE>

     circumstance be construed to be partners or joint venturers of Borrowers 
     or their Affiliates; neither the Managing Agent nor the Banks shall 
     under any circumstance be deemed to be in a relationship of confidence 
     or trust or a fiduciary relationship with Borrowers or their Affiliates, 
     or to owe any fiduciary duty to Borrowers or their Affiliates; neither 
     the Managing Agent nor the Banks undertake or assume any responsibility 
     or duty to Borrowers or their Affiliates to select, review, inspect, 
     supervise, pass judgment upon or inform Borrowers or their Affiliates of 
     any matter in connection with their Property or the operations of 
     Borrowers or their Affiliates; Borrowers and their Affiliates shall rely 
     entirely upon their own judgment with respect to such matters; and any 
     review, inspection, supervision, exercise of judgment or supply of 
     information undertaken or assumed by the Managing Agent or the Banks in 
     connection with such matters is solely for the protection of the 
     Managing Agent and the Banks and neither Borrowers nor any other Person 
     is entitled to rely thereon; and

          (d)  The Managing Agent and the Banks shall not be responsible or 
     liable to any Person for any loss, damage, liability or claim of any 
     kind relating to injury or death to Persons or damage to Property caused 
     by the actions, inaction or negligence of Borrowers and/or its 
     Affiliates and Borrowers hereby indemnify and hold the Managing Agent 
     and the Banks harmless on the terms set forth in Section 11.11 from any 
     such loss, damage, liability or claim.

          11.13  NO THIRD PARTIES BENEFITED.  This Agreement is made for the 
purpose of defining and setting forth certain obligations, rights and duties 
of Borrowers, the Managing Agent and the Banks in connection with the Loans, 
and is made for the sole benefit of Borrowers, the Managing Agent and the 
Banks, and the Managing Agent's and the Banks' successors and assigns.  
EXCEPT as provided in Sections 11.8 and 11.11, no other Person shall have any 
rights of any nature hereunder or by reason hereof.

          11.14  CONFIDENTIALITY.  Each Bank agrees to hold any confidential 
information that it may receive from Borrowers pursuant to this Agreement in 
confidence, EXCEPT for disclosure:  (a) to other Banks; (b) to legal counsel 
and accountants for Borrowers or any Bank; (c) to other professional advisors 
to Borrowers or any Bank, provided that the recipient has accepted such 
information subject to a confidentiality agreement substantially similar to 
this Section 11.14; (d) to regulatory officials having jurisdiction over that 
Bank; (e) as required by Law or legal process, 


                                     -102-
<PAGE>

provided that each Bank agrees to notify Borrowers of any such disclosures 
unless prohibited by applicable Laws, or in connection with any legal 
proceeding to which that Bank and any of Borrowers are adverse parties; and 
(f) to another financial institution in connection with a disposition or 
proposed disposition to that financial institution of all or part of that 
Bank's interests hereunder or a participation interest in its Notes, provided 
that the recipient has accepted such information subject to a confidentiality 
agreement substantially similar to this Section 11.14.  For purposes of the 
foregoing, "confidential information" shall mean any information respecting 
Parent or its Subsidiaries reasonably considered by Borrowers to be 
confidential, OTHER THAN (i) information previously filed with any 
Governmental Agency and available to the public, (ii) information previously 
published in any public medium from a source other than, directly or 
indirectly, that Bank, and (iii) information previously disclosed by 
Borrowers to any Person not associated with Borrowers which does not owe a 
professional duty of confidentiality to Borrowers or which has not executed 
an appropriate confidentiality agreement with Borrowers. Nothing in this 
Section shall be construed to create or give rise to any fiduciary duty on 
the part of the Managing Agent or the Banks to Borrowers.

          11.15  FURTHER ASSURANCES.  Borrowers shall, at their expense and 
without expense to the Banks or the Managing Agent, do, execute and deliver 
such further acts and documents as the Requisite Banks or the Managing Agent 
from time to time reasonably require for the assuring and confirming unto the 
Banks or the Managing Agent of the rights hereby created or intended now or 
hereafter so to be, or for carrying out the intention or facilitating the 
performance of the terms of any Loan Document.

          11.16  INTEGRATION.  This Agreement, together with the other Loan 
Documents and the letter agreements referred to in Sections 3.2, 3.5 and 
11.3, comprises the complete and integrated agreement of the parties on the 
subject matter hereof and supersedes all prior agreements, written or oral, 
on the subject matter hereof.  In the event of any conflict between the 
provisions of this Agreement and those of any other Loan Document, the 
provisions of this Agreement shall control and govern; PROVIDED that the 
inclusion of supplemental rights or remedies in favor of the Managing Agent 
or the Banks in any other Loan Document shall not be deemed a conflict with 
this Agreement.  Each Loan Document was drafted with the joint participation 
of the respective parties thereto and shall be construed neither against nor 
in favor of any party, but rather in accordance with the fair meaning thereof.


                                     -103-
<PAGE>

          11.17  GOVERNING LAW.  EXCEPT to the extent otherwise provided 
therein, each Loan Document shall be governed by, and construed and enforced 
in accordance with, the Laws of California applicable to contracts made and 
performed in California.

          11.18  SEVERABILITY OF PROVISIONS.  Any provision in any Loan 
Document that is held to be inoperative, unenforceable or invalid as to any 
party or in any jurisdiction shall, as to that party or jurisdiction, be 
inoperative, unenforceable or invalid without affecting the remaining 
provisions or the operation, enforceability or validity of that provision as 
to any other party or in any other jurisdiction, and to this end the 
provisions of all Loan Documents are declared to be severable.

          11.19  HEADINGS.  Article and Section headings in this Agreement 
and the other Loan Documents are included for convenience of reference only 
and are not part of this Agreement or the other Loan Documents for any other 
purpose.

          11.20  TIME OF THE ESSENCE.  Time is of the essence of the Loan 
Documents.

          11.21  FOREIGN BANKS AND PARTICIPANTS.  Each Bank that is 
incorporated or otherwise organized under the Laws of a jurisdiction other 
than the United States of America or any State thereof or the District of 
Columbia shall deliver to Borrowers (with a copy to the Managing Agent), on 
or before the Closing Date (or on or before accepting an assignment or 
receiving a participation interest herein pursuant to Section 11.8, if 
applicable) two duly completed copies, signed by a Responsible Official, of 
either Form 1001 (relating to such Bank and entitling it to a complete 
exemption from withholding on all payments to be made to such Bank by 
Borrowers pursuant to this Agreement) or Form 4224 (relating to all payments 
to be made to such Bank by the Borrowers pursuant to this Agreement) of the 
United States Internal Revenue Service or such other evidence (INCLUDING, if 
reasonably necessary, Form W-9) satisfactory to Borrowers and the Managing 
Agent that no withholding under the federal income tax laws is required with 
respect to such Bank.  Thereafter and from time to time, each such Bank shall 
(a) promptly submit to Borrowers (with a copy to the Managing Agent), such 
additional duly completed and signed copies of one of such forms (or such 
successor forms as shall be adopted from time to time by the relevant United 
States taxing authorities) as may then be available under then current United 
States laws and regulations to avoid, or such evidence as is satisfactory to 
Borrowers and the Managing Agent of any available exemption from, United 
States withholding 


                                     -104-
<PAGE>

taxes in respect of all payments to be made to such Bank by Borrowers 
pursuant to this Agreement and (b) take such steps as shall not be materially 
disadvantageous to it, in the reasonable judgment of such Bank, and as may be 
reasonably necessary (including the re-designation of its Eurodollar Lending 
Office, if any) to avoid any requirement of applicable Laws that Borrowers 
make any deduction or withholding for taxes from amounts payable to such 
Bank.  In the event that Borrowers or the Managing Agent become aware that a 
participation has been granted pursuant to Section 11.8(e) to a financial 
institution that is incorporated or otherwise organized under the Laws of a 
jurisdiction other than the United States of America, any State thereof or 
the District of Columbia, then, upon request made by Borrowers or the 
Managing Agent to the Bank which granted such participation, such Bank shall 
cause such participant financial institution to deliver the same documents 
and information to Borrowers and the Managing Agent as would be required 
under this Section if such financial institution were a Bank.

          11.22  HAZARDOUS MATERIAL INDEMNITY.  Each of Borrowers hereby 
agrees to indemnify, hold harmless and defend (by counsel reasonably 
satisfactory to the Managing Agent) the Managing Agent and each of the Banks 
and their respective directors, officers, employees, agents, successors and 
assigns from and against any and all claims, losses, damages, liabilities, 
fines, penalties, charges, administrative and judicial proceedings and 
orders, judgments, remedial action requirements, enforcement actions of any 
kind, and all costs and expenses incurred in connection therewith (including 
but not limited to reasonable attorneys' fees and the reasonably allocated 
costs of attorneys employed by the Managing Agent or any Bank, and expenses 
to the extent that the defense of any such action has not been assumed by 
Borrowers), arising directly or indirectly out of (i) the presence on, in, 
under or about any Real Property of any Hazardous Materials, or any releases 
or discharges of any Hazardous Materials on, under or from any Real Property 
and (ii) any activity carried on or undertaken on or off any Real Property by 
Borrowers or any of its predecessors in title, whether prior to or during the 
term of this Agreement, and whether by Borrowers or any predecessor in title 
or any employees, agents, contractors or subcontractors of Borrowers or any 
predecessor in title, or any third persons at any time occupying or present 
on any Real Property, in connection with the handling, treatment, removal, 
storage, decontamination, clean-up, transport or disposal of any Hazardous 
Materials at any time located or present on, in, under or about any Real 
Property.  The foregoing indemnity shall further apply to any residual 
contamination on, in, under or about any Real Property, or affecting any 
natural resources, and to any contamination of any Property or natural 


                                     -105-
<PAGE>

resources arising in connection with the generation, use, handling, storage, 
transport or disposal of any such Hazardous Materials, and irrespective of 
whether any of such activities were or will be undertaken in accordance with 
applicable Laws, but the foregoing indemnity shall not apply to Hazardous 
Materials on any Real Property, the presence of which is caused by the 
Managing Agent or the Banks.  Borrowers hereby acknowledge and agree that, 
notwithstanding any other provision of this Agreement or any of the other 
Loan Documents to the contrary, the obligations of Borrowers under this 
Section (and under Sections 4.18 and 5.10) shall be unlimited corporate 
obligations of Borrowers and shall NOT be secured by any Lien on any Real 
Property.  Any obligation or liability of Borrowers to any Indemnitee under 
this Section 11.22 shall survive the expiration or termination of this 
Agreement and the repayment of all Loans and the payment and performance of 
all other Obligations owed to the Banks. 

          11.23  JOINT AND SEVERAL.  Each of Borrowers shall be obligated for 
all of the Obligations on a joint and several basis, notwithstanding which of 
Borrowers may have directly received the proceeds of any particular Loan.  
Each of Borrowers acknowledges and agrees that, for purposes of the Loan 
Documents, Borrowers constitute a single integrated financial enterprise and 
that each receives a benefit from the availability of credit under this 
Agreement to all of Borrowers.  Each of Borrowers waive all defenses arising 
under the Laws of suretyship, to the extent such Laws are applicable, in 
connection with its joint and several obligations under this Agreement.  
Without limiting the foregoing, each of Borrowers agrees to the Joint 
Borrower Provisions set forth in EXHIBIT L, incorporated by this reference.

          11.24     REMOVAL OF A BANK.  As provided in Sections 2.9, 3.7 and 
3.8, Borrowers shall have the right to remove a Bank as a party to this 
Agreement if such Bank refuses (under certain circumstances) to consent to an 
extension of the Revolver Termination Date made pursuant to Section 2.9 or if 
such Bank is paid a material amount by Borrowers pursuant to Section 3.7 or 
Section 3.8. Upon notice from Borrowers, such Bank shall execute and deliver 
a Commitment Assignment and Acceptance covering that Bank's Pro Rata Share of 
the Commitments in favor of such Eligible Assignee as Borrowers may 
designate, subject to payment in full by such Eligible Assignee of all 
principal, interest and fees owing to such Bank through the date of 
assignment.  In addition (but only if Borrowers' right to remove the Bank 
arises under Section 2.9(b)), Borrowers may reduce the Commitments pursuant 
to Section 2.7 (and, for this purpose, the numerical requirements of such 
Section shall not apply) by an amount equal to that Bank's Pro Rata Share of 
the Commitments, pay to such Bank all principal, interest and fees owing to 
such Bank and release such Bank from its Pro 


                                     -106-
<PAGE>

Rata Share of the Commitments.

          11.25  WAIVER OF RIGHT TO TRIAL BY JURY.  EACH PARTY TO THIS 
AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, 
DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY 
WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTY 
HERETO OR ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS 
RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND 
WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY 
AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION 
SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS 
AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY 
COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE 
WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

          11.26  PURPORTED ORAL AMENDMENTS.  BORROWERS EXPRESSLY ACKNOWLEDGE 
THAT THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS MAY ONLY BE AMENDED OR 
MODIFIED, OR THE PROVISIONS HEREOF OR THEREOF WAIVED OR SUPPLEMENTED, BY AN 
INSTRUMENT IN WRITING THAT COMPLIES WITH SECTION 11.2.  BORROWERS AGREE THAT 
THEY WILL NOT RELY ON ANY COURSE OF DEALING, COURSE OF PERFORMANCE, OR ORAL 
OR WRITTEN STATEMENTS BY ANY REPRESENTATIVE OF THE MANAGING AGENT OR ANY BANK 
THAT DOES NOT COMPLY WITH SECTION 11.2 TO EFFECT AN AMENDMENT, MODIFICATION, 
WAIVER OR SUPPLEMENT TO THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly
executed as of the date first above written.
