     This document contains forward-looking statements within the meaning of 
Section 27A of the Securities Act of 1933, as amended, and Section 21E of the 
Securities Exchange Act of 1934, as amended.  Words such as "believes," 
"expects," "anticipates," "intends" and similar expressions are intended to 
identify some of the forward-looking statements regarding events, conditions 
and financial trends that may affect our 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 headings 
"Business Risks" and "Management's Discussion and Analysis of Financial 
Condition and Results of Operations."  We disclaim any obligation to update 
any of these factors or to announce publicly the result of any revisions to 
any of the forward-looking statements.

ITEM 1. BUSINESS. 

BACKGROUND

     Alexandria Real Estate Equities, Inc., a Maryland corporation formed in
October 1994, 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, 1998, we owned 51 Life Science Facilities (the
"Properties"), containing approximately 3.6 million rentable square feet of
office and laboratory space.

BUSINESS AND GROWTH STRATEGY.  

     We focus our operations and acquisition activities principally in:

     -    California (in the San Diego and San Francisco Bay areas);
     -    Seattle;
     -    suburban Washington, D.C. (including Maryland and Virginia);
     -    Eastern Massachusetts;
     -    New Jersey and suburban Philadelphia; and
     -    the Southeast (including Georgia and North Carolina).

     Our tenant base is broad and diverse within the Life Science Industry and
reflects our focus on regional, national and international tenants with
substantial financial and operational resources.  For a detailed description of
our Properties and tenants, see "Item 2. Properties."  Alexandria 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.

     We seek 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 we compute and view FFO as well as a discussion of other
measures of cash flow.  In particular, we seek to increase FFO and cash
available for distribution per share by:

                                       1
<PAGE>

     -    acquiring high quality Life Science Facilities at attractive returns
          in our target markets;
     -    realizing contractual rental rate escalations;
     -    retenanting and releasing space within our portfolio at higher rental
          rates and with minimal non-revenue enhancing tenant improvement costs;
     -    expanding existing Properties or converting existing office space to
          generic laboratory space that can be leased at higher rental rates;
     -    selectively developing properties on a retrofit or build-to-suit
          basis; and
     -    continuing to implement effective cost control measures, including
          negotiating pass-through provisions in tenant leases for operating
          expenses and certain capital expenditures.

     ACQUISITIONS.  We seek to identify and acquire high quality Life Science
Facilities in our target markets.  Critical evaluation of prospective property
acquisitions is an essential component of our acquisition strategy.  When
evaluating acquisition opportunities, we assess a full range of matters relating
to the properties, including the:

     -    location of the property and our strategy in the market;
     -    quality of existing and prospective tenants;
     -    condition and capacity of the building infrastructure;
     -    quality and generic characteristics of laboratory facilities;
     -    physical condition of the shell structure and common area
          improvements; and
     -    opportunities available for leasing vacant space and for retenanting
          occupied space. 

     INTERNAL GROWTH.  We seek to achieve internal growth from several sources. 
For example, we seek to:

     -    include rental rate escalation provisions in our leases;
     -    acquire undervalued or underperforming properties where we can improve
          investment returns through releasing of vacant space and replacement
          of existing tenants with new tenants at higher rental rates;
     -    achieve higher rental rates as existing leases expire; and
     -    expand existing facilities that are fully leased and/or convert
          existing office space to higher rent generic laboratory space.

Our 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 the leases are negotiated and the
increases are proposed.

     DEVELOPMENT.  We have emphasized acquisitions over development in pursuing
our growth objectives and intend to continue to do so in the future.  However,
we have pursued and will continue to pursue selective build-to-suit and retrofit
development projects where we expect to achieve investment returns that will
equal or exceed our returns on acquisitions.  We generally have undertaken
build-to-suit and retrofit projects only if our investment in infrastructure
will be substantially generic in nature and not tenant specific. 

     FINANCING/WORKING CAPITAL.  We believe that cash provided by operations and
our unsecured line of credit will be sufficient to fund our working capital
requirements.  We generally expect to finance future acquisitions through our
unsecured line of credit and then to periodically refinance some or all of that
indebtedness with additional equity or debt capital.  We also may issue shares
of our common stock or interests in our 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 our unsecured line of credit and other outstanding
indebtedness.

                                       2

BUSINESS RISKS

WE ARE DEPENDENT ON A SINGLE INDUSTRY FOR REVENUES FROM LEASE PAYMENTS

     Our strategy is to invest primarily in properties used by tenants in the
Life Science Industry.  Consequently, our revenues from lease payments are
largely dependent on a single industry.  If the Life Science Industry
experiences an economic downturn, our business could be adversely affected. 
Events within the Life Science Industry will have a more pronounced effect on
our ability to make distributions to our stockholders than if we had diversified
investments.  Also, our Properties may be better suited for a particular Life
Science Industry tenant and could require modification before we could release
vacant space to another Life Science Industry tenant.  Our Properties also may
not be suitable for lease to traditional office tenants without significant
expenditures on renovations.

SOME OF OUR TENANTS MUST OBTAIN REGULATORY APPROVAL OF THEIR PRODUCTS AND
MANUFACTURING PROCESSES, WHICH COULD ADVERSELY AFFECT THEIR ABILITY TO PAY US

     The products and manufacturing processes of some of our Life Science 
Industry tenants require governmental regulatory approval before they can be 
marketed and sold or used.  Any failure to obtain or any delay in obtaining 
these approvals could adversely affect the ability of the tenant to market 
and sell its products successfully and, therefore, its ability to make rental 
payments to us.  The process of obtaining these approvals is costly, 
time-consuming and often unpredictable.  We cannot assure you that our 
tenants will be able to obtain any required approvals.

     In addition, some of our tenants receive significant funding from federal,
state and local governments.  If any of this funding were decreased or
discontinued, the affected tenant could have difficulty making rental payments
to us.

WE COULD BE HELD LIABLE FOR DAMAGES RESULTING FROM OUR TENANTS' USE OF HAZARDOUS
MATERIALS

     Some of our Life Science Industry tenants engage in research and 
development activities that involve the controlled use of hazardous 
materials, chemicals and biological and radioactive compounds. In the event 
of contamination or injury from the use of these hazardous materials, we 
could be held liable for any damages that result.  This liability could 
exceed our resources and our environmental remediation coverage and could 
adversely affect our ability to make distributions to our stockholders.

     We and our tenants must comply with federal, state and local laws and
regulations that govern the use, manufacture, storage, handling and disposal of
hazardous materials and waste products.  Changes in these laws and regulations
could adversely affect our business or our tenants' business and their ability
to make rental payments to us.  

THE INABILITY OF ANY TENANT TO MAKE RENTAL PAYMENTS TO US COULD ADVERSELY AFFECT
OUR BUSINESS

     Our revenues are derived primarily from rental payments under our leases. 
Therefore, if our tenants, especially significant tenants, failed to make rental
payments under their leases, our financial condition and our ability to make
distributions to our stockholders could be adversely affected. 

     As of December 31, 1998, we had 158 leases with a total of 148 tenants. 
Twenty-four of our Properties were single-tenant properties.  Three of our
tenants accounted for approximately 18.4% of our aggregate Annualized Base Rent,
or approximately 7.1%, 6.4% and 4.9%, respectively.  "Annualized Base Rent"
means the annualized fixed base rental amount in effect as of December 31, 1998,
using rental revenue calculated on a straight-line basis in accordance with
generally accepted accounting principles.  Annualized Base Rent does not include
real estate taxes and insurance, common area and other operating expenses,
substantially all of which are borne by the tenants in the case of triple net
leases.

                                       3
<PAGE>

     The bankruptcy or insolvency of a major tenant also may adversely affect
the income produced by a Property.  If any of our tenants becomes a debtor in a
case under the U.S. Bankruptcy Code, we cannot evict that tenant solely because
of its bankruptcy.  The bankruptcy court might authorize the tenant to reject
and terminate its lease with us.  Our claim against such a tenant for unpaid,
future rent would be subject to a statutory cap that might be substantially less
than the remaining rent actually owed to us under the tenant's lease.  Any
shortfall in rent payments could adversely affect our cash flow and our ability
to make distributions to our stockholders.  

OUR U.S. GOVERNMENT TENANTS MAY NOT RECEIVE ANNUAL APPROPRIATIONS, WHICH COULD
ADVERSELY AFFECT THEIR ABILITY TO PAY US

     U.S. government tenants are subject to annual appropriations.  If one of 
our U.S. government tenants failed to receive its annual appropriation, it 
might not be able to make its lease payments to us.  In addition, defaults 
under leases with government tenants are governed by federal statute and not 
state eviction or rent deficiency laws.  All of our leases with U.S. 
government tenants provide that the government tenant may terminate the lease 
under certain circumstances.  As of December 31, 1998, leases with U.S. 
government tenants at our Properties accounted for approximately 8.0% of our 
aggregate Annualized Base Rent.

LOSS OF A TENANT COULD HAVE A NEGATIVE IMPACT ON OUR BUSINESS

     A lessee may not renew its lease upon the expiration of the initial term. 
In addition, we may not be able to locate a qualified replacement tenant upon
expiration or termination of a lease.  Consequently, we could lose the cash flow
from the affected Property, which could negatively impact our business.  We may
have to divert cash flow generated by other Properties to meet our mortgage
payments, if any, or to pay other expenses related to owning the affected
Property.  As of December 31, 1998, leases at our Properties representing
approximately 10.0% and 11.5% of the square footage of our Properties were
scheduled to expire in 1999 and 2000, respectively.

POOR ECONOMIC CONDITIONS IN OUR TARGET MARKETS COULD ADVERSELY AFFECT OUR
BUSINESS

     Our Properties are located only in the following markets:

     -    California (in the San Diego and San Francisco Bay areas);
     -    Seattle;
     -    suburban Washington, D.C. (including Maryland and Virginia);
     -    Eastern, Massachusetts;
     -    New Jersey and suburban Philadelphia; and
     -    the Southeast (including North Carolina and Georgia).

     As a result of this geographic concentration, we are dependent upon the
local economic conditions in each of these markets, including local real estate
conditions and competition.  If there is a downturn in the economy in any of
these markets, our operations and our ability to make distributions to
stockholders could be adversely affected.  We cannot assure you that these
markets will continue to grow or will remain favorable to the Life Science
Industry. 

WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH

     We have grown rapidly and expect to continue to grow by acquiring and
selectively developing additional properties.  To manage our growth effectively,
we must successfully integrate new acquisitions into our existing structure.  We
may not succeed with the integration.  In addition, we may not effectively
manage new properties, and new properties may not perform as expected.  If we
are unsuccessful in managing our growth, our business would be adversely
affected.

                                       4
<PAGE>

WE MAY NOT HAVE SUFFICIENT FUNDS TO REFINANCE OUR DEBT

     We use debt to finance our operations, including acquisitions of
properties.  Our incurrence of debt may have consequences, including the
following:

     -    our cash flow from operations may be not be sufficient to meet
          required payments of principal and interest;
     -    we may be forced to dispose of one or more of our Properties, possibly
          on disadvantageous terms, to make payments on our debt;
     -    we may default on our debt obligations, and the lenders or mortgagees
          may foreclose on our Properties that secure those loans;
     -    a foreclosure on one of our Properties could create taxable income
          without any accompanying cash proceeds to pay the tax;
     -    we may default under a mortgage loan that has cross default
          provisions, causing us automatically to default on another loan;
     -    we may not be able to refinance or extend our existing debt; and
     -    the terms of any refinancing or extension may not be as favorable as
          the terms of our existing debt.

     As of December 31, 1998, we had outstanding mortgage indebtedness of
approximately $115.8 million, secured by nine Properties, and outstanding debt
under our unsecured line of credit of approximately $194.0 million.

OUR LINE OF CREDIT RESTRICTS OUR ABILITY TO ENGAGE IN SOME BUSINESS ACTIVITIES

     Our $250 million unsecured revolving credit facility contains customary
negative covenants and other financial and operating covenants that, among other
things:

     -    restrict our ability to incur additional indebtedness;
     -    restrict our ability to make certain investments; 
     -    restrict our ability to merge with another company; 
     -    restrict our ability to make distributions to stockholders; 
     -    require us to maintain financial coverage ratios; and
     -    require us to maintain a pool of unencumbered assets approved by the
          lenders.

These restrictions could have a negative effect on our operations and our
ability to make distributions to our stockholders.

WE MAY NOT BE ABLE TO OBTAIN ADDITIONAL CAPITAL TO FURTHER OUR BUSINESS
OBJECTIVES

     Our ability to acquire or develop properties is dependent upon our ability
to obtain capital.  An inability to obtain capital on acceptable terms could
delay or prevent us from acquiring, structuring and closing desirable
investments, which would adversely affect our business.  Also, the issuance of
additional shares of capital stock or interests in subsidiaries to obtain
capital for the acquisition of additional properties could result in a dilution
of ownership for the then existing stockholders.

IF INTEREST RATES RISE, OUR DEBT SERVICE COSTS WILL INCREASE

     Borrowings outstanding under our unsecured line of credit bear interest at
a variable rate, and we may incur additional variable rate debt in the future. 
Increases in market interest rates would increase our interest expenses under
these debt instruments and would increase the costs of refinancing existing
indebtedness or obtaining new debt.  Accordingly, these increases could
adversely affect our financial position and our ability to make distributions to
stockholders. 

                                       5
<PAGE>

WE MAY NOT BE ABLE TO ACQUIRE PROPERTIES OR OPERATE THEM SUCCESSFULLY

     Our success depends in large part upon our ability to acquire additional
properties on satisfactory terms and to operate them successfully.  If we are
unable to do so, our business could be adversely affected.  In addition, the
acquisition of Life Science Facilities generally involves a higher per square
foot price than the acquisition of traditional suburban office properties.  

     The acquisition, ownership and operation of real estate is subject to many
risks, including: 

     -    our Properties may not perform as we expect;
     -    we may not be able to acquire a desired property because of
          competition from other real estate investors with significant capital;
     -    we may lease space at rates below our expectations;
     -    we may not be able to obtain financing on acceptable terms;
     -    we may overpay for new acquisitions; and
     -    we may underestimate the cost of improvements required to bring an
          acquired property up to standards established for the market position
          intended for that property.

If we encounter any of these risks, our business and our ability to make
payments to stockholders could be adversely affected.

WE MAY NOT BE ABLE TO COMPLETE DEVELOPMENT PROJECTS EFFECTIVELY

     Our expansion and development activities subject us to many risks,
including:

     -    possible delays in construction;
     -    budget overruns;
     -    increasing costs of materials;
     -    financing availability;
     -    volatility in interest rates;
     -    labor availability;
     -    timing of the commencement of rental payments; and
     -    other property development uncertainties.

     In addition, expansion and development activities, regardless of whether
they are ultimately successful, typically require a substantial portion of
management's time and attention.  This may detract management from focusing on
other operational activities.  If we are unable to successfully complete
expansion and development projects, our business may be adversely affected.

IF OUR REVENUES ARE LESS THAN OUR EXPENSES, WE MAY HAVE TO BORROW ADDITIONAL
FUNDS AND WE MAY NOT MAKE DISTRIBUTIONS TO OUR STOCKHOLDERS

     If our Properties do not generate revenues sufficient to meet our operating
expenses, including debt service and other capital expenditures, we may have to
borrow additional amounts to cover fixed costs and cash flow needs.  This could
adversely affect our ability to make distributions to our stockholders.  Factors
that could adversely affect the revenues from and the value of our Properties
include:

     -    national and local economic climates;
     -    competition from other Life Science Facilities;
     -    real estate conditions in our target markets;
     -    our ability to collect rent payments;

                                       6
<PAGE>

     -    availability of financing;
     -    changes in interest rate levels;
     -    vacancies at our Properties and our ability to release space;
     -    changes in tax or other regulatory laws;
     -    cost of compliance with government regulation;
     -    illiquidity of real estate investments; and
     -    increased operating costs.

     In addition, if a lease at a Property is not a triple net lease, we will
have greater expenses associated with that Property.  Significant expenditures,
such as mortgage payments, real estate taxes, insurance and maintenance costs,
generally are fixed and do not decrease when revenues at the related property
decrease.  

IMPROVEMENTS TO LIFE SCIENCE FACILITIES ARE MORE COSTLY THAN TRADITIONAL OFFICE
SPACE

     Our Properties contain generic infrastructure improvements that are more
costly than other property types.  These improvements include:

     -    reinforced concrete floors;
     -    upgraded roof loading capacity;
     -    significantly upgraded electrical, gas and plumbing infrastructure;
     -    heavy-duty HVAC systems; and
     -    laboratory benches.

     Although we have historically been able to reflect the additional
investment in generic infrastructure improvements in higher rental rates, we
cannot assure you that we will be able to continue to do so in the future.

WE MAY NOT BE ABLE TO SELL OUR PROPERTIES QUICKLY TO RAISE MONEY

     Investments in real estate are relatively illiquid.  Accordingly, we may
not be able to sell our Properties when we desire or at acceptable prices in
response to changes in economic or other conditions.  In addition, the Internal
Revenue Code limits our ability to sell properties held for fewer than four
years.  These limitations on our ability to sell our Properties may adversely
affect our cash flows and our ability to make distributions to stockholders.

WE FACE SUBSTANTIAL COMPETITION IN OUR TARGET MARKETS

     The significant competition for business in our target markets could have
an adverse effect on our operations.  We compete for investment opportunities
with: 

     -    insurance companies;
     -    pension and investment funds;
     -    partnerships;
     -    developers;
     -    investment companies; and
     -    other REITs.

     Many of these entities have substantially greater financial resources than
we do and may be able to accept more risk than we can manage.  These entities
may be less sensitive to risks with respect to the creditworthiness of a tenant
or the geographic proximity of its investments.  Competition from other entities
also may reduce the number of suitable investment opportunities offered to us or
may increase the bargaining power of property owners seeking to sell.

OUR PROPERTIES MAY HAVE DEFECTS UNKNOWN TO US

     All of our Properties have been under our management for less than five
years, and we have owned a substantial majority of them for less than two years.
Any of our Properties may have characteristics or deficiencies unknown to us
that could adversely affect the Property's valuation or revenue potential. 

IF WE FAIL TO QUALIFY AS A REIT, WE WOULD BE TAXED AT CORPORATE RATES AND WOULD
NOT BE ABLE TO TAKE CERTAIN DEDUCTIONS WHEN COMPUTING OUR TAXABLE INCOME

     If in any taxable year we fail to qualify as a REIT:

     -    we would be subject to federal income tax on our taxable income at
          regular corporate rates;
     -    we would not be allowed a deduction for distributions to stockholders
          in computing taxable income;
     -    unless we were entitled to relief under the Internal Revenue Code, we
          would also be disqualified from treatment as a REIT for the four
          taxable years following the year during which we lost qualification;
          and
     -    we would no longer be required by the Internal Revenue Code to make
          any distributions to our stockholders.

     As a result of the additional tax liability, we might need to borrow funds
or liquidate certain investments in order to pay the applicable tax. 
Accordingly, funds available for investment or distribution to our stockholders
would be reduced for each of the years involved. 

     Qualification as a REIT involves the application of highly technical and
complex provisions of the Internal Revenue Code to our operations and the
determination of various factual matters and circumstances not entirely within
our control.  There are only limited judicial or administrative interpretations
of these provisions.  Although we  believe that we have operated since January
1996 in a manner so as to qualify as a REIT, we cannot assure you that we are or
will remain so qualified. 

     In addition, although we are not aware of any pending tax legislation that
would adversely affect our ability to operate as a REIT, new legislation,
regulations, administrative interpretations or court decisions could change the
tax laws or interpretations of the tax laws regarding qualification as a REIT,
or the federal income tax consequences of that qualification, in an adverse
manner.

     Although certain of our officers and directors have extensive experience in
the acquisition, leasing, operation financing and development of real
properties, prior to commencement of our operations, no officer had significant
experience in operating a business in accordance with the requirements for
maintaining qualification as a REIT under the Internal Revenue Code.

THERE ARE LIMITS ON THE OWNERSHIP OF OUR CAPITAL STOCK; A STOCKHOLDER MAY LOSE
BENEFICIAL OWNERSHIP OF ITS SHARES OF OUR COMMON STOCK BECAUSE OF THE OWNERSHIP
LIMITS

     The Internal Revenue Code provides that, in order for us to maintain our
qualification as a REIT, not more than 50% of the value of our outstanding
capital stock may be owned, directly or constructively, by five or fewer
individuals or entities.

     In addition, our charter prohibits, with certain limited exceptions, direct
or constructive ownership of shares of our capital stock representing more than
9.8% of the combined total value of outstanding shares of our capital stock by
any person (the "Ownership Limit").  Our Board of Directors may exempt a
stockholder from the Ownership Limit if, prior to the exemption, our Board of
Directors receives any information it deems necessary to determine or ensure our
status as a REIT.

                                       8
<PAGE>

     The constructive ownership rules are complex and may cause shares of our
common stock owned directly or constructively by a group of related individuals
or entities to be constructively owned by one individual or entity.  A transfer
of shares to a person who, as a result of the transfer, violates the Ownership
Limit may be void or may be transferred to a trust, for the benefit of one or
more qualified charitable organizations designated by us.  In that case, the
intended transferee will have only a right to share, to the extent of the
transferee's original purchase price for such shares, in proceeds from the
trust's sale of those shares. 

THE OWNERSHIP LIMIT AND OTHER PROVISIONS OF OUR CHARTER MAY DELAY OR PREVENT
TRANSACTIONS THAT WOULD OTHERWISE BE BENEFICIAL TO OUR STOCKHOLDERS

     The Ownership Limit may have the effect of delaying, deferring or 
preventing a transaction or a change in control that might involve a premium 
price for our common stock or otherwise be in the best interest of our 
stockholders.

     Our charter allows our Board of Directors to cause us to issue 
additional authorized but unissued shares of our common stock or preferred 
stock without any stockholder approval.  The issuance of preferred stock 
could make it more difficult for another party to gain control of Alexandria. 
 In addition, our Board of Directors could establish a series of preferred 
stock that could delay, defer or prevent a transaction that might involve a 
premium price for our common stock or otherwise be in the best interest of 
our common stockholders.  Our Board of Directors could also establish a 
series of preferred stock that has a dividend preference, which may adversely 
affect our ability to pay dividends on our common stock.  

OUR INSURANCE MAY NOT COVER ALL POTENTIAL LOSSES

     If we experience a loss at any of our Properties that is not covered by
insurance or that exceeds our insurance policy limits, we could lose the capital
invested in the affected Property and, possibly, future revenues from that
Property.  In addition, we would continue to be obligated on any mortgage
indebtedness or other obligations related to the affected Properties.  

     We carry comprehensive liability, fire, extended coverage and rental loss
insurance with respect to our Properties.  We have obtained earthquake insurance
for all of our Properties because many of them are located in the vicinity of
active earthquake faults. We also carry environmental remediation insurance and
have title insurance policies on all of our Properties.  We obtain our title
insurance policies when we acquire the Property.  As a result, each policy
covers an amount equal to the initial purchase price of each Property.  Any one
of our title insurance policies may be in an amount less than the current value
of the related Property. 

     We believe that our insurance policy specifications, insured limits and
deductibles are consistent with those customarily carried for similar
properties.   In addition, we require our tenants to maintain comprehensive
insurance, including liability and casualty insurance, that is customarily
obtained for similar properties. There are, however, certain types of losses
that we and our tenants do not generally insure because they are either
uninsurable or because it is not economical to insure against them.  In
addition, certain disaster-type insurance (covering catastrophic events) may not
be available or may only be available at rates that, in the opinion of our
management, are prohibitive. 

WE COULD INCUR SIGNIFICANT COSTS COMPLYING WITH ENVIRONMENTAL LAWS 

     Federal, state and local environmental laws and regulations may require us,
as a current or previous owner or operator of real estate, to investigate and
clean up hazardous or toxic substances or petroleum products released at or from
any of our Properties.  The cost of investigating and cleaning up contamination
could be substantial.  In addition, the presence of contamination, or the
failure to properly clean it up, may adversely affect our ability to sell or
rent an affected Property or to borrow funds using that Property as collateral.

                                       9
<PAGE>

     Under environmental laws and regulations, we may have to pay governmental
entities or third parties for property damage and for investigation and clean-up
costs incurred by those parties relating to contaminated Properties regardless
of whether we knew of or caused the presence of the contaminants.  Even if more
than one person may have been responsible for the contamination, we may be held
responsible for all of the clean-up costs.  In addition, third parties may sue
us for damages and costs resulting from environmental contamination from that
site.  

     Environmental laws also govern the presence, maintenance and removal of
asbestos-containing materials.  These laws may impose fines and penalties on us
for the release of asbestos-containing materials and may allow third parties to
seek recovery from us for personal injury from exposure to asbestos fibers.  We
have detected asbestos-containing materials at some of our Properties, but we do
not expect that it will result in material environmental costs or liabilities to
us.

     Environmental 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.

     Some of our tenants routinely handle hazardous substances and wastes as 
part of their operations at our Properties.  Environmental laws and 
regulations subject our tenants, and potentially us, to liability resulting 
from these activities.  Environmental liabilities could also affect a 
tenant's ability to make rental payments to us.  We require our tenants to 
comply with these environmental laws and regulations and to indemnify us for 
any related liabilities.  We are not aware of any material noncompliance, 
liability or claim relating to hazardous or toxic substances or petroleum 
products in connection with any of our Properties.  

     Independent environmental consultants have conducted Phase I or similar
environmental assessments at all of our Properties.  We anticipate that
consultants will conduct similar environmental assessments on our future
acquisitions.  This type of assessment generally includes a site inspection,
interviews and a public records review, but no subsurface sampling.  These
assessments and certain follow-up investigations of our Properties have not
revealed any environmental liability that we believe would have a material
adverse effect on our business or results of operations.  The follow-up
investigations included, as appropriate:

     -    asbestos surveys;
     -    radon surveys;
     -    lead surveys;
     -    additional public records review;
     -    subsurface sampling; and
     -    other testing.

     Nevertheless, it is possible that the assessments on our Properties have
not revealed, or that the assessments on future acquisitions will not reveal,
all environmental liabilities.  Consequently, there may be material
environmental liabilities of which we are unaware that may result in substantial
costs to us or our tenants.  


WE MAY INCUR SIGNIFICANT COSTS COMPLYING WITH THE AMERICANS WITH DISABILITIES
ACT AND SIMILAR LAWS

     Under the Americans with Disabilities Act, places of public accommodation
and/or commercial facilities are required to meet federal requirements related
to access and use by disabled persons.  We may be required to make 

                                      10
<PAGE>

substantial capital expenditures at our Properties to comply with this law.  
In addition, our noncompliance could result in the imposition of fines or an 
award of damages to private litigants.  

     A number of additional federal, state and local laws and regulations exist
regarding access by disabled persons.  These regulations may require
modifications to our Properties or may affect future renovations.  This may
limit the overall returns on our investments.

     We believe that our Properties are substantially in compliance with the
present requirements of the Americans with Disabilities Act and similar laws. 
We have not, however, conducted an audit or an investigation of all or our
Properties to determine our compliance. 

WE MAY INCUR SIGNIFICANT COSTS IF WE FAIL TO COMPLY WITH LAWS OR IF LAWS CHANGE

     Our Properties are subject to many federal, state and local regulatory
requirements and to state and local fire and life-safety requirements.  If we do
not comply with all of these requirements, we may have to pay fines to
governmental authorities or damage awards to private litigants.  

     We believe that our Properties are currently in compliance with all of
these regulatory requirements.  We do not know whether these requirements will
change or whether new requirements will be imposed.  Changes in these regulatory
requirements could require us to make significant unanticipated expenditures. 
These expenditures could have an adverse effect on us and our ability to make
distributions to stockholders.

THE LOSS OF SERVICES OF ANY OF OUR EXECUTIVE OFFICERS COULD ADVERSELY AFFECT US

     We depend upon the services of our executive officers.  The loss of
services of any one of our executive officers could have an adverse effect on
our business, financial condition and prospects.  We use the extensive personal
and business relationships that members of our management have developed over
time with owners of Life Science Facilities and with major Life Science Industry
tenants.  We have employment agreements with most of our executive officers, but
we cannot assure you that our executive officers will remain employed with us.

WE MAY CHANGE OUR BUSINESS POLICIES WITHOUT STOCKHOLDER APPROVAL

     Our Board of Directors determines all of our business policies, with
management's input, including our:

     -    status as a REIT;
     -    investment initiatives;
     -    growth management;
     -    debt incurrence;
     -    general financing;
     -    acquisition and selective development activities;
     -    shareholder distributions; and
     -    operations.

     Our Board of Directors may amend or revise these policies at any time
without a vote of our stockholders.  A change in these policies could adversely
affect us and our ability to make distributions to our stockholders. 

                                      11
<PAGE>

WE COULD BECOME HIGHLY LEVERAGED AND OUR DEBT SERVICE OBLIGATIONS COULD INCREASE

     Our organizational documents do not limit the amount of debt that we may
incur.  Therefore, we could become highly leveraged.  This would result in an
increase in our debt service obligations that could adversely affect our cash
flow and our ability to make distributions to our stockholders.  

     We have adopted a policy of incurring debt only if upon such incurrence our
debt to total market capitalization ratio would not exceed 57.5%.  Our total
market capitalization is the market value of our capital stock, including
interests exchangeable for shares of capital stock, plus total debt.  Our Board
of Directors could, however, change or eliminate this policy at any time. 
Higher leverage also increases the risk of default on our debt obligations.

OUR DISTRIBUTIONS TO STOCKHOLDERS MAY DECLINE AT ANY TIME

     We may not continue our current level of distributions to stockholders. 
Our Board of Directors will determine future distributions based on a number of
factors, including:

     -    our amount of cash available for distribution;
     -    our financial condition;
     -    any decision by our Board of Directors to reinvest funds rather than
          to distribute such funds;
     -    our capital expenditures;
     -    the annual distribution requirements under the REIT provisions of the
          Internal Revenue Code; and
     -    other factors our Board of Directors deems relevant.

THE YEAR 2000 PROBLEM COULD DISRUPT OUR BUSINESS OPERATIONS

     The year 2000 problem results from an inability of computer systems to
accurately recognize dates on and after January 1, 2000.  The year 2000 problem
could lead to significant disruptions in our operations and in our tenants'
operations, which could adversely affect their ability to make rental payments
to us.

     We have formed a Year 2000 Task Force to address the effects of the year
2000 problem on us.  Our internal accounting systems have been tested and are
currently working without year 2000 or systems-related problems.  Some of our
operations, however, are not currently year 2000 compliant, but we expect to be
compliant by mid-1999.  We are also evaluating our significant third-party
vendors, our financial institutions and our major tenants for their year 2000
readiness.  

     We have identified the following as the principal risks to us associated
with the year 2000 problem:

     -    disruption of our operations due to the failure of third parties,
          including tenants, vendors and financial institutions, to achieve year
          2000 readiness; and
     -    business interruption due to building system failures at our
          Properties.

     We are using internal staff and outside consultants to address our year
2000 problems.  Our year 2000 costs to date have been minimal, and we do not
expect future costs to be material.  However, unexpected future costs could be
significant.  We cannot guarantee that all of our systems will be year 2000
compliant on time or that other companies on which we rely will be compliant in
a timely manner.  A failure in either case could result in material adverse
effects on our financial condition and our results of operations.

POSSIBLE FUTURE SALES OF SHARES OF OUR COMMON STOCK COULD ADVERSELY AFFECT THE
MARKET PRICE OF OUR COMMON STOCK

     We cannot predict the effect, if any, of future sales of shares of our
common stock on the market price of our common stock prevailing from time to
time.  Sales of substantial amounts of capital stock (including common stock

                                      12
<PAGE>

issued upon the exercise of stock options), or the perception that such sales 
could occur, may adversely affect prevailing market prices for our common 
stock. 

     As of December 31, 1998, some of our stockholders held registration rights
with respect to 1,765,923 shares of our common stock.  In addition, we have
reserved for issuance to our officers, directors and employees pursuant to our
Amended and Restated 1997 Stock Award and Incentive Plan that number of shares
of our common stock equal to 10% of the total number of shares outstanding at
any time, provided that in no event may the number of shares of our common stock
available for issuance under our stock option plan exceed 3,000,000 shares at
any time.  

     As of December 31, 1998, we had outstanding options to purchase 821,500
shares of our common stock, of which options to purchase 252,834 shares of our
common stock were exercisable.  We have filed a registration statement with
respect to the issuance of shares of our common stock pursuant to grants under
the stock option plan.  In addition, any shares issued under our stock option
plan will be available for sale in the public market from time to time without
restriction by persons who are not our Affiliates (as defined in Rule 144
promulgated under the Securities Act).  Affiliates will be able to sell shares
of our common stock pursuant to exemptions from the registration requirements or
upon registration.

FINANCIAL INFORMATION REGARDING INDUSTRY SEGMENTS AND OPERATIONS.  

     We are involved only in the real estate industry segment within the United
States, and we have no foreign operations.  Accordingly, all financial
statements contained in this report relate to the real estate industry segment. 
See "Item 2. Properties" and "Item 8. Financial Statements and Supplementary
Data" for detailed financial information regarding our business.

EMPLOYEES 

     As of December 31, 1998, we had 29 full-time employees and one part-time
employee.

ITEM 2. PROPERTIES. 

GENERAL.

     Our Properties range in size from approximately 15,000 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.  These improvements typically are generic to Life Science
Industry tenants rather than specific to a particular tenant.  As a result, we
believe 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 include:

     -    reinforced concrete floors;
     -    upgraded roof loading capacity;
     -    increased floor to ceiling heights;
     -    heavy-duty HVAC systems;
     -    advanced environmental control technology;
     -    significantly upgraded electrical, gas and plumbing infrastructure;
          and
     -    laboratory benches.

     We own fee simple title in each of our Properties, except with respect to:

                                      13
<PAGE>

     -    1311, 1401 and 1431 Harbor Bay Parkway, in which we own a commercial
          condominium interest, together with an undivided interest in the
          common areas of the project in which the Property is a part; and 
     -    Buildings 79 & 96, Charlestown Navy Yard, and 8000/9000/10000 Virginia
          Manor Road, in which we own ground leasehold interests.

     As of December 31, 1998, we had 158 leases with a total of 148 tenants, and
24 of our Properties were single-tenant properties.  Leases in our 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,
1998:  

     -    approximately 78% of our 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;
     -    approximately 17% of our leases (on a square footage basis) required
          the tenants to pay a majority of operating expenses; 
     -    approximately 83% of our 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; and
     -    approximately 78% of our 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 we believe would typically be borne by the
          landlord in traditional office leases.

     Our leases also typically give us the right to review and approve tenant
alterations to the Property.  Generally, tenant-installed improvements remain
our property after termination of the lease.  However, we are permitted under
the terms of most of our leases to require that the tenant remove the
improvements and restore the premises to their original condition. 

     As of December 31, 1998, we managed 41 of our Properties.  The remaining
Properties were managed by third-party professional management companies.  We
make all material decisions with respect to all of our Properties.

     The following table sets forth pertinent information with respect to our
Properties as of December 31, 1998:

ITEM 3. LEGAL PROCEEDINGS. 

     On August 10, 1998, we filed a demand for arbitration against Mr. Alan 
Gold, our former President, alleging various claims arising from his 
employment relationship and seeking declaratory relief. On October 8, 1998, 
Mr. Gold filed a response and alleged claims against us, arising from his 
employment relationship, which we also expect to be resolved in the 
arbitration. The arbitration is scheduled to take place April 19, 1999 
through April 23, 1999.

     To our knowledge, no other litigation is pending against us, 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 our financial 
condition, results of operations or cash flows.

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

     We did not submit any matters to a vote of security holders in the 
fourth quarter of the fiscal year ended December 31, 1998.

(1)  Period commencing on the date our common stock began trading on the NYSE
     and ending on December 31, 1998.  Prior to our initial public offering in
     June 1997 and the 1,765.923 to 1 stock split in connection therewith, we
     paid the following dividends on our common stock during 1997:  (1) February
     3, 1997, $1,549.82 per share; (2) March 31, 1997, $750.01 per share; and
     (3) June 5, 1997, $475.00 per share.

(2)  We paid a distribution of $0.1275 per share of our 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.

     Future distributions on our common stock will be determined by our Board 
of Directors and will be dependent upon a number of factors, including actual 
cash available for distribution, our financial condition and capital 
requirements, the annual distribution requirements under the REIT provisions 
of the Internal Revenue Code and such other factors as our Board of Directors 
deems relevant.  To maintain our qualification as a REIT, we must make annual 
distributions to stockholders of at least 95% of our taxable income, 
determined without regard to deductions for dividends paid and by excluding 
any net capital gains.  Under certain circumstances, we may be required to 
make distributions in excess of cash flow available for distributions to meet 
the distribution requirements.  In that case, we may borrow funds or may 
raise funds through the issuance of additional debt or equity capital.  We 
cannot assure you that we will make any future distributions.

     accounted for as a financing cost.

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

     Paper ("White Paper"). The White Paper defines FFO as net income (loss) 
     (computed in accordance with GAAP), excluding gains (or losses) from debt 
     restructuring and sales of property, and excluding amounts for 
     extraordinary and non-recurring 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

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

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

OVERVIEW

     In June 1997, we completed an initial public offering of our common 
stock (the "Offering").  We issued 7,762,500 shares of our common stock in 
connection with the Offering (including shares issued in the related exercise 
of the underwriters' overallotment option) and raised $138.9 million, net of 
underwriting discounts and commissions, advisory fees and offering costs.

     Since the Offering, we have continued to devote substantially all of our
resources to the acquisition, selective development and management of high
quality, strategically located properties leased principally to tenants in the
life science industry (we refer to these properties as "Life Science
Facilities").

     In 1998, we:

     -    Sold 1,150,000 shares of our common stock in May to PaineWebber
          Incorporated for inclusion in the PaineWebber Equity Trust REIT Series
          I, a unit investment trust.  We received aggregate proceeds from this
          transaction, net of underwriting discounts and commissions, advisory
          fees and offering costs, of approximately $32.7 million.

     -    Increased our borrowing capacity under our line of credit from $150
          million to $250 million in August, thereby providing additional
          flexibility in pursuing acquisitions and funding tenant improvements
          and capital expenditures.

     -    Acquired a total of 29 properties with approximately 1.8 million in
          rentable square feet, including two properties aggregating
          approximately 105,000 rentable square feet that will undergo major
          renovation.

     Our primary source of revenue is rental income and tenant recoveries from
leases at the properties we own.  Of the 51 properties we owned as of
December 31, 1998, four were acquired in calendar year 1994, eight in 1996 (the
"1996 Acquired Properties"), 10 in 1997 (the "1997 Acquired Properties") and 29
in 1998 (the "1998 Acquired Properties").  As a result of our acquisition
activities, there were significant increases in total revenues and expenses for
1998 as compared to 1997.

RESULTS OF OPERATIONS

COMPARISON OF THE YEAR ENDED DECEMBER 31, 1998 TO THE YEAR ENDED DECEMBER 31,
1997

     Rental revenue increased by $22.9 million, or 89%, to $48.5 million for 
1998 compared to $25.6 million for 1997.  The increase resulted primarily 
from the 1997 Acquired Properties being owned for a full period and the 
addition of the 1998 Acquired Properties.  A portion of the increase was due 
to $277,000 in rental termination payments received in 1998 associated with 
leases at two of the properties.  Rental revenue from the properties we 
acquired before January 1, 1997 (the "Same Properties") increased by 
$234,000, or 1.6%, due to increases in rental rates and occupancy.

     Tenant recoveries increased by $2.9 million, or 35%, to $11.3 million 
for 1998 compared to $8.4 million for 1997.  The increase resulted primarily 
from the 1997 Acquired Properties being owned for a full period and the 
addition of the 1998 Acquired Properties.  Tenant recoveries for the Same 
Properties increased by $149,000, or 2.8%, generally due to the improved 
identification and recovery of costs at certain properties.

                                       24

<PAGE>

     Interest and other income increased by $398,000, or 48%, to $1.2 million 
for 1998 compared to $836,000 for 1997, resulting primarily from $511,000 of 
interest income from a $6.0 million secured loan made in connection with the 
acquisition of one of the 1998 Acquired Properties.  This increase was 
partially offset by a decrease in interest income resulting from a lower 
level of cash equivalents in 1998 compared to 1997, because cash equivalents 
had been used to acquire properties.

     Rental operating expenses increased by $4.6 million, or 52%, to $13.4 
million for 1998 compared to $8.8 million for 1997.  The increase resulted 
almost entirely from the 1997 Acquired Properties being owned for a full 
period and the addition of the 1998 Acquired Properties.  Operating expenses 
for the Same Properties decreased by $145,000, or 2.5%, primarily due to 
lower premiums on our blanket property and liability insurance policies.

     The following is a comparison of property operating data computed under 
generally accepted accounting principles ("GAAP Basis") and under generally 
accepted accounting principles, adjusted to exclude the effect of straight 
line rent adjustments required by GAAP ("Cash Basis") for the Same Properties 
(in thousands, except percentage data):

     (1)  Revenue and operating expenses are computed in accordance with GAAP,
          except that revenue excludes the effect of straight line rent
          adjustments.

     General and administrative expenses increased by $1.4 million, or 56%, 
to $3.9 million for 1998 compared to $2.5 million for 1997 due to owning a 
larger portfolio of properties in 1998 compared to 1997 and increased costs 
incurred as a result of being a public company for a full year.

     Interest expense increased by $7.0 million, or 100%, to $14.0 million 
for 1998 compared to $7.0 million for 1997.  The increase resulted from 
indebtedness incurred to acquire the 1997 Acquired Properties and the 1998 
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.

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

                                       25

<PAGE>

     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 we 
repaid with proceeds of the Offering and $148,000 in loan costs associated 
with the payoff of debt in November 1997.

     Depreciation and amortization increased by $5.4 million, or 110%, to 
$10.3 million for 1998 compared to $4.9 million for 1997.  The increase 
resulted primarily from depreciation associated with the 1997 Acquired 
Properties being owned for a full period and the addition of the 1998 
Acquired Properties.

     As a result of the foregoing, net income was $19.4 million for 1998 
compared to a net loss of $2.8 million for 1997.

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.  Rental revenue from the properties 
we acquired before January 1, 1996 (the "1997 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.  Tenant recoveries for the 1997 
Same Properties increased by $416,000, or 19%, due to an increase in 
operating expenses (particularly utilities) being passed through to the 
tenants.  

     Interest and 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.  Operating expenses 
for the 1997 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 our larger 
scope of operations and increased costs incurred as a result of being a 
public company.

     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 and the 1997 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.

     The amounts shown for special bonus, post-retirement benefit expense, 
stock compensation expense, Acquisition LLC financing costs and write-off 
unamortized loan costs in 1997 relate primarily to transactions associated 
with the Offering.  We have described them in the prior section under " - 
Comparison of the Year Ended December 31, 1998 to the Year Ended December 31, 
1997."

                                      26

<PAGE>

     Depreciation and amortization increased by $2.5 million, or 104%, 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.

LIQUIDITY AND CAPITAL RESOURCES

CASH FLOWS

     Net cash provided by operating activities for 1998 increased by $22.2 
million to $26.1 million compared to $3.9 million for 1997.  The increase 
resulted primarily from operating cash flows from the addition of the 1997 
Acquired Properties and the 1998 Acquired Properties.

     Net cash used in investing activities increased by $159.2 million to 
$(246.8) million for 1998 compared to $(87.6) million for 1997.  The increase 
resulted from $200.6 million used for the acquisition of the 1998 Acquired 
Properties, $21.2 million used for additions to rental properties, $18.9 
million used for additions to land under development and $6.0 million used 
for the addition of a note receivable made in connection with the acquisition 
of one of the 1998 Acquired Properties.

     Net cash provided by financing activities increased by $136.0 million to 
$220.1 million for 1998 compared to $84.1 million for 1997.  This increase 
resulted from $35.2 million in net proceeds from secured debt, $171.0 million 
in borrowings under our unsecured line of credit, $32.7 million in net 
proceeds from the issuance of our common stock and $386,000 in net proceeds 
from the exercise of stock options, partially offset by payments of $19.2 
million in dividends payable on our common stock.

COMMITMENTS

     We are committed to complete the construction of a building and certain 
related improvements in San Diego, California at a remaining cost of 
approximately $4.9 million under the terms of two leases.  In addition, we 
are committed to complete the construction of a building and certain related 
improvements in Gaithersburg, Maryland at a remaining cost of between $7.8 
million and $16.8 million (depending on the level of improvements to the 
facility elected by the tenant) under the terms of a lease.  Under the terms 
of the lease, the tenant's rental rate will be adjusted depending on the 
ultimate cost of the improvements.

     We are also committed to fund approximately $11.1 million for 
investments in limited partnerships and rental properties, including the 
construction of tenant improvements under the terms of various leases.  Of 
this amount, approximately $3.2 million has been set aside in restricted cash 
accounts to complete the conversion of existing space into higher rent 
generic laboratory space (as well as certain related improvements) at 
1102/1124 Columbia Street and 3000/3018 Western Avenue.

UNSECURED LINE OF CREDIT

     Alexandria has an unsecured line of credit which provides for borrowings 
of up to $250 million.  Prior to August 1998, our line of credit provided for 
borrowings of up to $150 million.  Borrowings under the line of credit bear 
interest at a floating rate based on our 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, we must elect to fix the rate for a 
period of one, two, three or six months.

     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. 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 we acquire additional unencumbered properties, borrowings 
available under the line of credit will increase, but may not exceed $250 
million.  As of December 31, 1998, borrowings under the line of credit were 
limited to approximately $214,000,000, and carried a weighted average 
interest rate of 6.48%.

     The line of credit expires 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 September 1998, we entered into an interest rate swap agreement with 
BankBoston, N.A. (the "Bank") to hedge our exposure to variable interest 
rates associated with our line of credit.  Interest paid is calculated at a 
fixed interest rate of 5.43% through May 31, 2000 on a notional amount of $50 
million and interest received is calculated at one month LIBOR.  The net 
difference between the interest paid and the interest received is reflected 
as an adjustment to interest expense.  The fair value of the swap agreement 
and changes in the fair value as a result of changes in market interest rates 
are not recognized in the financial statements.  

OTHER RESOURCES AND LIQUIDITY REQUIREMENTS

     On May 29, 1998, we sold 1,150,000 shares of our common stock to 
PaineWebber Incorporated for inclusion in the PaineWebber Equity Trust REIT 
Series I, a unit investment trust.  The shares were issued at a price of 
$30.5625 per share (before discounts and commissions) resulting in aggregate 
proceeds to us, net of offering costs of $2.4 million, of approximately $32.7 
million.

     We expect to continue meeting our short-term liquidity and capital 
requirements generally through our working capital and net cash provided by 
operating activities.  We believe that the net cash provided by operating 
activities will continue to be sufficient to make distributions necessary to 
enable us to continue qualifying as a real estate investment trust. We also 
believe that net cash provided by operations will be sufficient to fund our 
recurring non-revenue enhancing capital expenditures, tenant improvements and 
leasing commissions.

                                       29
<PAGE>

     We expect to meet certain long-term liquidity requirements, such as
property acquisitions, property development activities, 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 our properties, we have
obtained Phase I environmental assessments to ascertain the existence of any
environmental liabilities or other issues.  The Phase I environmental
assessments of our properties have not revealed any environmental liabilities
that we believe would have a material adverse effect on our financial condition
or results of operations taken as a whole, nor are we aware of any material
environmental liabilities.

CAPITAL EXPENDITURES, TENANT IMPROVEMENTS AND LEASING COSTS

     The following table shows total and weighted average per square foot
capital expenditures, tenant improvements and leasing costs (excluding capital
expenditures and tenant improvements that are recoverable from tenants or are
revenue-enhancing) for the years ended December 31, 1998, 1997, 1996 and 1995,
attributable to leases that commenced at our properties after our acquisition.

</TABLE>

     Capital expenditures fluctuate in any given period due to the nature,
extent, and timing of improvements required and the extent to which they are
recoverable from our tenants.  We maintain an active preventive maintenance
program at each of our properties to minimize required capital improvements.  

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

INFLATION

     As of December 31, 1998, approximately 78% of our 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 17% of our leases (on
a square footage basis) required the tenants to pay a majority of operating
expenses.  Approximately 83% of our leases (on a square footage basis) contain

                                      30

<PAGE>

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,
we do not believe that our earnings or cash flow are subject to any significant
risk of inflation.  An increase in inflation, however, could result in an
increase in our variable rate borrowing cost, including borrowings under the
unsecured line of credit.

IMPACT OF THE YEAR 2000

     The year 2000 issue is the result of computer programs being written using
two digits rather than four digits to define the applicable year.  Any of our
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000.  This could result in a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send tenant
invoices, provide building services or engage in similar normal business
activities.

     We rely on computer technologies to operate our business.  In October 1998,
we formed an internal task force to identify, assess and evaluate our critical
systems to determine which year 2000 related problems may cause system errors or
failures.  We have identified three major areas as critical systems:  (i)
internal accounting systems, (ii) systems of significant tenants, vendors and
financial institutions; and (iii) internal building systems at our properties. 
We have engaged consulting professionals from a nationally recognized accounting
firm to review our plans and assist us with our solutions.

     The following discussion of our year 2000 project contains numerous 
forward-looking statements based on inherently uncertain information.  The 
cost of our evaluation and the date on which we plan to complete our internal 
evaluation and related remediation projects are based on our best estimates.  
We derived these estimates using a number of assumptions of future events, 
including the continued availability of internal and external resources, 
third-party modifications and other factors.  However, there can be no 
guarantee that these estimates will be achieved, and actual results may be 
materially different from those anticipated.  Moreover, although we believe 
that we will be operating in a year 2000 compliant manner prior to December 
31, 1999, there can be no assurance that any failure to modify a critical 
system would not have a material adverse effect on our operations.

READINESS

     Our year 2000 project is designed to ensure that all critical systems have
been evaluated and will be suitable for continued use into and beyond the year
2000.  We expect to have completed our identification and initial evaluation of
critical systems in the first quarter of 1999, and we expect we will have
implemented substantially all of the necessary remedial actions by mid-1999. 

     We have completed our review of our internal accounting systems.  Our most
significant accounting systems, our general ledger system and our accounts
payable system, are currently year 2000 compliant.  The systems will be tested,
but we do not anticipate year 2000 problems.  Our billing system is currently
not year 2000 compliant.  We have been notified by the vendor that they will be
distributing the year 2000 compliant upgrade to the software at no additional
cost by June 1999.  Once we receive this upgrade, the software will be tested
for compatibility and year 2000 compliance.  

     We place a high degree of reliance on computer systems of third parties,
such as tenants, vendors and financial institutions.  Although we are assessing
the readiness of these third parties, there can be no guarantee that the failure
of these third parties to modify their systems in advance of December 31, 1999
would not have a material adverse effect on our operations.  We have surveyed
our most significant third-party vendors and financial institutions, and all
surveyed indicated that they have implemented year 2000 programs.  We are
currently in the process of surveying all major vendors and suppliers for their
year 2000 readiness.  In addition, we are in the process of surveying our
significant tenants for their year 2000 readiness and expect to complete such
tenant assessments in the first quarter of 1999.  We are continually
participating in such surveys with new tenants, vendors and other third-party
suppliers.  If future risk 

                                      31

<PAGE>

assessments of third-party suppliers or tenants indicate significant exposure 
from a supplier's year 2000 problem, such supplier or tenant will be asked to 
demonstrate how such problems will be addressed. We believe that we have 
viable alternatives for each of our major vendors.  

     The final critical system the task force is evaluating consists of internal
systems in our properties that may have embedded microprocessors with potential
year 2000 problems, mainly building systems, including heating, ventilation and
air conditioning systems, elevators and security systems.  We are in the process
of identifying the areas and systems that use embedded microprocessors and will
determine whether any modification or replacement is necessary.  We anticipate
using the services of outside experts to assist us with this phase of our year
2000 project.  The evaluation of these areas is in process and is expected to be
completed in the first quarter of 1999, and any required modifications are
expected to be made by mid-1999.

COST

     We do not expect our year 2000 project costs, including the costs of any
remedial activities and outside experts, to be material.  The aggregate cost of
purchasing conversion packages for the accounting systems and the cost to survey
tenants, vendors and financial institutions are not expected to be material.  In
addition, any costs incurred to replace or upgrade building systems will
constitute property maintenance costs, and are therefore generally recoverable
from the tenants pursuant to the terms of their existing leases. 

RISKS

     We believe that the principal risks associated with the year 2000 issue
include the risk of disruption of our operations due to operational failures of
third parties, including tenants, vendors and financial institutions, and the
risk of business interruption due to building system failures.  We do not
believe that the risk of disruptions due to operational failures of vendors or
financial institutions is significant, because our major vendors and financial
institutions are currently year 2000 compliant, and we believe we have viable
alternatives for such suppliers.  If any of our major tenants do not become year
2000 compliant on schedule, such tenant's operations and financial condition
could be adversely affected, which may impact the tenant's ability to meet its
rent obligations.  Similarly, if our building systems failed due to year 2000
problems, services to our properties and tenants, such as mechanical and
security services, could be interrupted, resulting in potential rent disputes
with the tenants.  We believe, however, that our early involvement in
identifying, assessing and evaluating our critical systems should minimize the
risk of year 2000 problems to our operations.

CONTINGENCY PLANS 

     We believe that development of contingency plans for significant exposures
to potential year 2000 problems are integral to our planning process.  Once we
have completed our identification and evaluation of critical systems and have
completed the subsequent remedial action phase, we will again assess our
exposure to year 2000 problems.  Based on this assessment, we intend to develop
appropriate contingency plans for the systems.  Because we anticipate being
substantially year 2000 compliant by mid-1999, we believe that adequate time
exists to ensure that alternatives can be developed, assessed and implemented
prior to the end of 1999.  Based on our assessment of the success or adequacy of
these alternatives, we intend to develop contingency plans.  We cannot give
assurance, however, that failure to develop an alternative or an appropriate
contingency plan would not have a material adverse effect on our operations.

FUNDS FROM OPERATIONS

     We believe 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 our ability to incur and service debt, to
make capital expenditures and to make distributions.  We compute FFO in
accordance with standards established by the Board of Governors of the 

                                      32

<PAGE>

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 amounts 
available for our 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 principles ("GAAP")), excluding gains (or 
losses) from debt restructuring and sales of property, and excluding amounts 
for extraordinary and non-recurring 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 our financial performance or to cash flows from operating 
activities (determined in accordance with GAAP) as a measure of our 
liquidity, nor is it indicative of funds available to fund our cash needs, 
including our ability to make distributions. (See "-Cash Flows" for 
information regarding these measures of cash flow).

     The following table presents our FFO for the years ended December 31, 1998,
1997, and 1996 (in thousands):

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Market risk is the exposure to loss resulting from changes in interest
rates, foreign currency exchange rates, commodity prices and equity prices.  The
primary market risk to which we are exposed is interest rate risk, which is
sensitive to many factors, including governmental monetary and tax policies,
domestic and international economic and political considerations and other
factors that are beyond our control.  

     In order to modify and manage the interest characteristics of our
outstanding debt and limit the effects of interest rates on our operations, we
may utilize a variety of financial instruments, including interest rate swaps,
caps, floors and other interest rate exchange contracts.  The use of these types
of instruments to hedge our exposure to changes in interest rates carries
additional risks such as counter-party credit risk and legal enforceability of
hedging contracts.

     Our future earnings, cash flows and fair values relating to financial
instruments are primarily dependent upon prevalent market rates of interest,
such as LIBOR.  However, due to the purchase of our interest rate swap
agreement, the effects of interest rate changes are reduced.  Based on interest
rates at December 31, 1998, a 1% increase in interest rates on our line of
credit would decrease annual future earnings and cash flows, after considering
the effect of our interest rate swap agreement, by approximately $1.4 million. 
A 1% decrease in interest rates on our line of credit would increase annual
future earnings and cash flows, after considering the effect of our interest
rate swap agreement, by approximately $1.4 million.  A 1% increase interest
rates on our secured debt and interest rate swap agreement would decrease their
fair value by approximately $7.7 million.  A 1% decrease in interest rates on
our secured debt and interest rate swap agreement would increase their fair
value by approximately $8.8 million.  A 1% increase or decrease in interest
rates on our secured note receivable would not have a material impact on its
fair value.

     These amounts are determined by considering the impact of the hypothetical
interest rates on our borrowing cost and interest rate swap agreement.  These
analyses do not consider the effects of the reduced level of overall economic
activity that could exist in such an environment.  Further, in the event of a
change of such magnitude, we would consider taking actions to further mitigate
our exposure to the change.  However, due to the uncertainty of the specific
actions that would be taken and their possible effects, the sensitivity analysis
assumes no changes in our capital structure.

                         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, 1998 and 1997, and the related consolidated statements of operations, 
stockholders' equity, and cash flows for the years ended December 31, 1998, 
1997 and 1996. 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, 1998 and 1997, and the consolidated results 
of its operations and its cash flows for the years ended December 31, 1998, 
1997 and 1996, 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 
financial information set forth therein.

                                                           /s/ Ernst & Young LLP

             ALEXANDRIA REAL ESTATE EQUITIES, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BACKGROUND

Alexandria Real Estate Equities, Inc. is a real estate investment trust 
("REIT") formed in 1994. We are engaged primarily in the acquisition, 
management, and selective development of properties for lease principally to 
participants in the life science industry (we refer to these properties as 
"Life Science Facilities"). As of December 31, 1998, our portfolio consisted 
of 51 properties in nine states with approximately 3,588,000 rentable square 
feet, compared to 22 properties in four states with approximately 1,748,000 
rentable square feet as of December 31, 1997.

On June 2, 1997, we completed our 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 we 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 following transactions also occurred in June 1997 in connection with the 
Offering:

     -   We repaid debt of approximately $77,723,000, including (i) mortgage
         debt of $72,698,000, (ii) debt of $2,500,000 outstanding under our
         prior unsecured line of credit, and (iii) debt of $2,525,000 to Health
         Science Properties Holding Corporation ("Holdings"). Holdings owned all
         of our common stock prior to the Offering and 14% of our common stock
         as of December 31, 1998.

     -   We obtained two new mortgage loans totaling $15,360,000.

     -   We 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 12).

     -   Each previously outstanding share of our common stock was split into
         1,765.923 shares of common stock. The share data as of and for the year
         ended December 31, 1996 has been restated to reflect the effects of the
         stock split.

         were redeemed at their stated value ($1,200 in the aggregate) (see Note

1. BACKGROUND (CONTINUED)

     -   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 Notes 8 and 9).

     -   Officers, directors and certain employees of Alexandria were granted an
         aggregate of 152,615 shares of our common stock. In addition, our
         officers, directors and certain employees were granted options to
         purchase 57,000 shares of our common stock in substitution for stock
         options previously issued by Holdings (see Notes 8 and 11). These
         options were exercised at a nominal exercise price in connection with
         the Offering.

     -   Officers, directors and employees of Alexandria were granted options
         under the 1997 stock option plan to purchase an aggregate of 600,000
         shares of our common stock at the Offering price (see Note 11).

     -   A special bonus of $353,000 was paid to an officer of Alexandria.


2. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The consolidated financial statements include the accounts of Alexandria and 
its subsidiaries. All significant intercompany balances and transactions have 
been eliminated.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted 
accounting principles requires us 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

We consider all highly liquid investments with original maturities of three 
months or less when purchased to be cash equivalents.

RECLASSIFICATIONS

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

RENTAL PROPERTIES AND LAND UNDER DEVELOPMENT

Properties and land under development are stated at the lower of cost or 
estimated fair value. Write-downs to estimated fair value would be recognized 
when impairment indicators are present and a property's estimated 
undiscounted future cash flows, before interest charges, are less than its 
book value. In that situation, we would recognize an impairment loss to the 
extent the carrying amount exceeds the fair value of the property. Based on 
our assessment, no write-downs to estimated fair value were necessary for the 
periods presented.

The cost of maintenance and repairs is 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.

the terms of the related loans and included in interest expense. Loan fees 
and costs, net of related amortization, totaled $3,424,000 and $1,350,000 as 
of December 31, 1998 and 1997, respectively.

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 respective 
lease term. We include amounts currently recognized as income, and expected 
to be received in later years, in tenant receivables and deferred rent on our 
consolidated balance sheet. Amounts received currently, but recognized as 
income in future years, are included in unearned rent on our consolidated 
balance sheet.

OTHER INCOME

Other income consists of interest income and other income associated with the 
operations of the properties. Interest income was $978,000, $588,000 and 
$118,000 in 1998, 1997 and 1996, respectively.

LEASING COMMISSIONS

Leasing commissions are amortized on a straight-line basis over the term of 
the related lease. Leasing commissions, net of related amortization, totaled 
$4,856,000 and $847,000 as of December 31, 1998 and 1997, respectively.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amount of cash and cash equivalents approximates fair value 
because their maturity is less than three months. The carrying amount of our 
secured note receivable approximates fair value because the applicable 
interest rate approximates the market rate for this loan.

The fair value of our secured notes payable was estimated using discounted 
cash flows analyses based on borrowing rates we believe we could obtain with 
similar terms and maturities. As of December 31, 1998 and 1997, the fair 
value of our secured notes payable was approximately $118,310,000 and 
$46,822,000, respectively.

NET INCOME (LOSS) PER SHARE

Historical per share data has not been presented for 1997 and 1996 because it 
is not meaningful due to the material changes in our capital structure as a 
result of the Offering. Instead, we have presented net income (loss) per 
share for these years on a pro forma basis, giving effect to the Offering and 
related transactions.

NET INCOME (LOSS) 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.

We have adopted Statement of Financial Accounting Standards No. 128, 
"Earnings per Share," and have restated pro forma net income per share for 
the year ended December 31, 1996. Basic and diluted net income per share are 
the same for 1997 because the stock options outstanding as of December 31, 
1997 were antidilutive. There were no dilutive stock options on a pro forma 
basis for 1996.

The following table shows the computation of net income (loss) per share of 
common stock outstanding:

OPERATING SEGMENTS

In June 1997, the Financial Accounting Standards Board issued Statement of 
Financial Accounting Standards No. 131, "Disclosures About Segments of an 
Enterprise and Related Information," which is effective for years beginning 
after December 15, 1997. Statement 131 establishes standards for the way that 
public business enterprises report information about operating segments. 
Statement 131 also establishes standards for related disclosure about 
products and services, geographic areas, and major customers. Since we 
operate as a single segment, the implementation of Statement 131 did not have 
an impact on how we report our results of operations.

INCOME TAXES

As a REIT, we are not subject to federal income taxation as long as we meet a 
number of organizational and operational requirements and distribute all of 
our taxable income to our stockholders. Since we believe we have met these 
requirements and our distributions exceeded taxable income, no federal income 
tax provision has been reflected in the accompanying consolidated financial 
statements for the years ended December 31, 1998, 1997 and 1996. If we fail 
to qualify as a REIT in any taxable year, we will be subject to federal 
income tax on our taxable income at regular corporate tax rates. For the 
years ended December 31, 1998 and 1996, we reported that none of our 
distributions with respect to common stock represented a return of capital 
for federal income tax purposes. For the year ended December 31, 1997, we 
reported that 37.6% of our distributions with respect to common stock 
represented a return of capital.

3. RENTAL PROPERTIES (CONTINUED)

We lease space under noncancelable leases with remaining terms of one to 18 
years.

A majority of our leases require that the lessee pay all taxes, maintenance, 
insurance and certain other operating expenses applicable to the leased 
properties.

We capitalize 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 for the years ended December 31, 1998 and 
1997 was $2,199,000 and $96,000, respectively. Total interest incurred for 
the years ended December 31, 1998, 1997 and 1996 was $16,232,000, $7,139,000 
and $6,327,000, respectively.

4. SECURED NOTE RECEIVABLE

In connection with the acquisition of a Life Science Facility in San Diego, 
California in March 1998, we made a $6,000,000 loan to the sole tenant of the 
property, fully secured by a first deed of trust on certain improvements at 
the property. The loan bears interest at a rate of 11% per year, payable 
monthly, and matures in March 2002. The loan is cross-defaulted to the lease 
with the sole tenant. Under certain circumstances, we may obtain title to the 
improvements that secure the loan, and, in such event, we may also require 
the sole tenant at the property to lease such improvements back from us for 
an additional rental amount.

5. UNSECURED LINE OF CREDIT

Alexandria has an unsecured line of credit which provides for borrowings of 
up to $250 million. Prior to August 1998, our line of credit provided for 
borrowings of up to $150 million. Borrowings under the line of credit bear 
interest at a floating rate based on our 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, we must elect to fix the rate for a 
period of one, two, three or six months.

                                       F-12

<PAGE>

5. UNSECURED LINE OF CREDIT (CONTINUED)

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. 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 we acquire additional unencumbered properties, borrowings available under 
the line of credit will increase, but may not exceed $250 million. As of 
December 31, 1998, borrowings under the line of credit were limited to 
approximately $214,000,000, and carried a weighted average interest rate of 
6.48%.

The line of credit expires 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.

We enter into interest rate swap agreements to modify the interest 
characteristics of our outstanding debt. These agreements involve an exchange 
of fixed and floating interest payments without the exchange of the 
underlying principal amount (the "notional amount").

In September 1998, we entered into an interest rate swap agreement with 
BankBoston, N.A. (the "Bank") to hedge our exposure to variable interest 
rates associated with our line of credit. Interest paid is calculated at a 
fixed interest rate of 5.43% through May 31, 2000 on a notional amount of $50 
million and interest received is calculated at one month LIBOR. The net 
difference between the interest paid and the interest received is reflected 
as an adjustment to interest expense. The fair value of the swap agreement 
and changes in the fair value as a result of changes in market interest rates 
are not recognized in the financial statements. We are exposed to loss in the 
event the Bank is unable to perform under the swap agreement or in the event 
one month LIBOR is less than 5.43%.

In June 1998, the Financial Accounting Standards Board issued Statement No. 
133, "Accounting for Derivative Instruments and Hedging Activities," which is 
required to be adopted in fiscal years beginning after June 15, 1999. When 
adopted, Statement 133 will require us to recognize all derivatives on the 
balance sheet at fair value. Based on the definitions provided in Statement 
133, our interest rate swap agreement will be classified as a cash flow 
hedge, with changes in the fair value recorded as an adjustment to 
comprehensive income, which will be a separate component of shareholders' 
equity.

7. ISSUANCE OF COMMON STOCK

On May 29, 1998, we sold 1,150,000 shares of our common stock to PaineWebber 
Incorporated for inclusion in the PaineWebber Equity Trust REIT Series I, a 
unit investment trust. The shares were issued at a price of $30.5625 per 
share (before discounts and commissions) resulting in aggregate proceeds to 
us, net of offering costs of $2.4 million, of approximately $32.7 million.

8. NON-CASH TRANSACTIONS

During 1998, we assumed two secured notes payable in connection with the 
acquisition of the following properties (in thousands):

</TABLE>

Stock compensation expense in 1997 represents non-cash compensation expense 
associated with stock grants and stock options issued to our officers, 
directors and certain employees in connection with the Offering (see Note 11).

In connection with the Offering in 1997, all previously outstanding shares of 
Series U preferred stock and Series V preferred stock were converted into 
shares of common stock (see Note 1). 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).

9. PREFERRED STOCK AND EXCESS STOCK

SERIES V CUMULATIVE CONVERTIBLE PREFERRED STOCK

Prior to the Offering, we 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%, considering cash received from prior dividends.

                                       F-15

<PAGE>

9. PREFERRED STOCK AND EXCESS 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 in 1996 
were deducted from the proceeds of the issuance. Until the conversion of the 
Series V preferred stock into shares of common stock in 1997, we 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

Our charter 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, 1998.

10. COMMITMENTS AND CONTINGENCIES

LITIGATION

We currently are not subject to any material legal proceedings or claims, nor 
are we aware of any material legal proceedings or claims being threatened.

POST-RETIREMENT BENEFIT

In 1997, in connection with the Offering, an officer of Alexandria retired. 
In connection with the officer's retirement, we 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 life of the executive's spouse as of the date of the agreement. In 
1997 and 1996, a post-retirement expense was recorded for past services equal 
to $632,000 and $438,000, respectively (pursuant to a prior agreement). As of 
December 31, 1998 and 1997, the accrued liability for post-retirement benefit 
was $1,110,000 and $1,037,000, respectively. For the years ended December 31, 
1998 and 1997, we paid $150,000 and $75,000, respectively, under the 
retirement agreement, of which $77,000 and $42,000, respectively, represented 
interest.

EMPLOYEE RETIREMENT SAVINGS PLAN

Effective January 1, 1997, we adopted a retirement savings plan pursuant to 
Section 401(k) of the Internal Revenue Code ("Code") whereby our employees 
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 that we match the employees' contributions, which amounted to 
$89,000 and $36,000, respectively, for the years ended December 31, 1998 and 
1997. Employees who participate in the plan are immediately vested in their 
contributions and in the matching contributions of the company.

CONCENTRATION OF CREDIT RISK

We maintain our 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. We believe that the 
risk is not significant.

We are dependent on rental income from relatively few tenants in the life 
science industry. The inability of any single tenant to make its lease 
payments could adversely affect our operations. As of December 31, 1998, we 
had 158 leases with a total of 148 tenants, and 24 of our 51 properties were 
leased to a single tenant. At December 31, 1998, our three largest tenants 
accounted for approximately 18.4% of our aggregate annualized base rent.

We generally do not require collateral or other security from our tenants, 
other than security deposits. As of December 31, 1998, we have $6.1 million 
in irrevocable letters of credit available from certain tenants as security 
deposits for 15 leases.

COMMITMENTS

We are committed to complete the construction of a building and certain 
related improvements in San Diego, California at a remaining cost of 
approximately $4.9 million under the terms of two leases. In addition, we are 
committed to complete the construction of a building and certain related 
improvements in Gaithersburg, Maryland at a remaining cost of between $7.8 
million and $16.8 million (depending on the level of improvements to the 
facility elected by the tenant) under the terms of a lease. Under the terms 
of the lease, the tenant's rental rate will be adjusted depending on the 
ultimate cost of the improvements.

We are also committed to fund approximately $11.1 million for investments in 
limited partnerships and rental properties, including the construction of 
tenant improvements under the terms of various leases. Of this amount, 
approximately $3.2 million has been set aside in restricted cash accounts to 
complete the conversion of existing space into higher rent generic laboratory 
space (as well as certain related improvements) at 1102/1124 Columbia Street 
and 3000/3018 Western Avenue.

11. STOCK OPTION PLANS AND STOCK GRANTS

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

1997 STOCK OPTION PLAN

In connection with the Offering, we adopted a stock option and incentive plan 
(the "1997 Stock Option Plan") for the purpose of attracting and retaining 
the best personnel, providing for additional incentives, and promoting the 
success of the company by providing employees the opportunity to acquire 
common stock. Options under our plan have been granted at prices that are 
equal to the market value of the stock on the date of grant and expire ten 
years after the date of grant. Employee options vest ratably in three annual 
installments from the date of grant. Non-employee director options are 
exercisable immediately upon the date of grant.

The options outstanding under the 1997 Stock Option Plan expire at various 
dates through November 2008. As of December 31, 1998, a total of 379,793 
shares were reserved for the granting of future options under the 1997 Stock 
Option Plan.

1997 STOCK OPTION PLAN (CONTINUED)

Although we have elected to follow APB 25, pro forma information regarding 
net income and net income (loss) per share is required by Financial 
Accounting Standards Board Statement No. 123, "Accounting for Stock-Based 
Compensation." This information has been determined as if we had accounted 
for our employee stock options under the fair value method under Statement 
123. 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 1998 and 1997:

Exercise prices for options outstanding as of December 31, 1998 range from

outstanding is 8.8 years.

PRIOR STOCK OPTION PLAN

Prior to the Offering, we had a ten-year incentive and nonqualified stock 
option plan for certain of our employees and non-employee directors.

Under this 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 Alexandria in substitution 
for previously granted Holdings Stock Options. As such, in connection with 
the Offering, our officers, directors and certain employees received 
substitute stock options to purchase 57,000 shares of our common stock under 
the prior plan. These 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, we recognized $1,187,000 of stock compensation 
expense in 1997.

11. STOCK OPTION PLANS AND STOCK GRANTS (CONTINUED)

PRIOR STOCK OPTION PLAN (CONTINUED)

No compensation expense was recorded with respect to Holdings Stock Options 
issued during the year ended December 31, 1996 since they were issued with an 
exercise price equal to the then fair market value of the Holdings common 
stock.

STOCK GRANTS

In connection with the Offering, we granted our officers, directors and 
certain employees an aggregate of 152,615 shares of common stock. As a result 
of the grants, we recorded stock compensation expense of $3,052,000.

12. PURCHASE OF ACQUISITION LLC

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

The purchase price we paid for the membership interests ($58,844,000) 
exceeded the cost incurred by the Acquisition LLC to acquire the properties 
($51,871,000). The excess of this purchase price over the cost of the 
Acquisition LLC to acquire the properties ($6,973,000) is reflected as a 
financing cost in 1997 in our consolidated statement of operations.

13. RELATED PARTY TRANSACTIONS

During 1998, 1997 and 1996, we incurred $2,762,000, $3,358,000 and 
$1,708,000, respectively, for legal services provided by a firm of which a 
minority shareholder of Holdings is a member.

During 1998, 1997 and 1996, we were reimbursed $270,000, $21,000 and $18,000, 
respectively, for payroll, accounting and office space incurred on behalf of 
Holdings.

of common stock (including the shares issued upon exercise of the 
underwriters' over-allotment option). The shares were issued at a price of 
$28.125 per share resulting in aggregate proceeds, net of underwriters'

                              SEVERANCE AGREEMENT

              THIS AGREEMENT, dated January 1, 1999, (the "Effective Date") 
is made by and between Alexandria Real Estate Equities, Inc., a Maryland 
corporation (the "Company"), and Lynn A. Shapiro ("Executive").

              WHEREAS, the Company considers it essential to the best 
interests of its stockholders to foster the continued employment of key 
management personnel; and
              
              WHEREAS, the Board of Directors has determined that appropriate 
steps should be taken to reinforce and encourage the continued attention and 
dedication of members of the Company's management, including Executive, who 
shall serve as General Counsel and Assistant Secretary of the Company.

              NOW, THEREFORE, the Company and Executive hereby agree as 
follows:

       1.     TERM OF AGREEMENT.

              The term of this Agreement shall commence on the Effective Date 
and shall continue in effect through the first anniversary of the Effective 
Date (the "Term"); PROVIDED, HOWEVER, that on each anniversary of the 
Effective Date during the Term, the Term shall automatically be extended for 
one additional year unless, not later than 90 days prior to any such 
anniversary, the Company or Executive shall have given written notice not to 
extend the Term.

       2.     COMPENSATION OTHER THAN SEVERANCE PAYMENTS.

              If Executive's employment shall be terminated for any reason 
during the Term, the Company shall pay Executive's full salary to Executive 
accrued through the date of Executive's termination of employment (the "Date 
of Termination") at the rate in effect immediately prior to the Date of 
Termination.

<PAGE>

       3.     SEVERANCE PAYMENTS.

              If  Executive's employment is terminated by the Company other 
than for Cause (as defined below), then the Company shall pay Executive a 
severance payment equal to nine (9) months ("Severance Period") of 
Executive's annualized base salary ("Severance Payments"), in addition to any 
payments to which Executive is entitled under Section 2 hereof. Such 
Severance Payments shall be payable in substantially equal semimonthly 
installments during the Severance Period in accordance with the standard 
policies of the Company in existence from time-to-time; provided, that if 
such termination is within six months following a Change in Control (as 
defined below), the Company shall pay Executive such Severance Payment in a 
lump sum within sixty (60) days following a Change in Control.  In addition, 
if  Executive's employment is terminated by the Company other than for Cause 
within six months following a Change in Control, the vesting of any options 
held by Executive to purchase shares of stock of the Company shall 
immediately accelerate upon such termination following a Change in Control.

              Executive shall not be entitled to receive a Severance Payment 
hereunder if she voluntarily terminates her employment or is terminated by 
reason of death or disability or for Cause. 

              3.1    CAUSE.  For purposes of this Agreement, "Cause" shall mean
the following:

              (i)    Executive's Material breach, repudiation or failure to
                     comply with or perform any of the terms of this Agreement,
                     any of Executive's duties, or any of the Company's policies
                     or procedures (including without limitation any such
                     policies or procedures relating to conflicts of interests
                     or standards of business conduct) or deliberate
                     interference with the compliance by any other employee of
                     the Company with any of the foregoing;

              (ii)   the conviction of Executive for, or pleading by Executive
                     of no contest (or similar plea) to, fraud, embezzlement,
                     misappropriation of assets, malicious mischief, or any
                     felony, other than a crime for which vicarious liability is
                     imposed upon Executive solely by reason of Executive's
                     position with the Company and not by reason of Executive's
                     conduct; or


                                       2

<PAGE>

              (iii)  any other act, omission, event or condition constituting
                     cause for the discharge of any employee under applicable
                     law.

              Before terminating the Agreement for Cause, the Company first 
shall have given Executive written notice specifying the nature of the 
breach, repudiation or failure to comply and thirty (30) days thereafter in 
which to cure such breach, repudiation or failure to comply, and Executive 
shall have failed to cure.  For purposes of this Section 3, "Material" shall 
mean a breach, repudiation or failure that the Board determines has resulted 
or could result in material injury to the Company.

              3.2    CHANGE IN CONTROL  for purposes of this agreement, a 
"Change in Control" shall be deemed to have occurred if:

                     (i)  Any Person, as such term is used in section 3(a)(9)

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

solicitation, relating to the election of directors of the Company) whose 
appointment or election by the Board or nomination for election by the 
Company's stockholders was approved or recommended 

                                       3

<PAGE>

by a vote of at least two-thirds (2/3) of the directors then still in 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 Company with any other corporation, other than (A) a merger or 
consolidation which would result in the voting securities of the Company 
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 Company or any subsidiary of the Company, at 
least seventy-five percent (75%) of the combined voting power of the 
securities of the Company 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 Company (or 
similar transaction) in which no Person is or becomes the Beneficial Owner, 
directly or indirectly, of securities of the Company (not including in the 
securities beneficially owned by such Person any securities acquired directly 
from the Company or its affiliates other than in connection with the 
acquisition by the Company or its affiliates of a business) representing 
twenty-five percent (25%) or more of the combined voting power of the 
Company's then outstanding securities; or 

                     (iv)  The stockholders of the Company approve a plan of 
complete liquidation or dissolution of the Company or there is consummated an 
agreement for the sale or disposition by the Company of all or substantially 
all of the Company's assets, other than a sale or disposition by the Company 
of all or substantially all of the Company'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 Company in substantially the same 
proportions as their ownership of the Company immediately prior to such sale.

       4.     OFFSET.  

              Although Executive 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 shall be 
reduced by any compensation earned by or provided to Executive as the result 
of employment by an employer other than the Company prior to the expiration 
of the Term.

       5.     NONCOMPETITION.

              During the Term, including the period, if any, with respect to 
which Executive shall be entitled to Severance Payments, Executive shall not 
engage in any activity that is or may be competitive with the business of the 
Company, directly or indirectly, whether or not for compensation, including, 
but not limited to, providing services similar to those provided by the

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. The arbitrator shall make such determination and

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 extent possible.

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

Corporation terminates this Agreement without Cause (as defined below), 
Officer shall be entitled to a severance payment equal to seven and one half

purposes of this Agreement, "Cause" shall mean the following:

       (i)    Officer's Material breach, repudiation or failure to comply with
              or perform any of the terms of this Agreement, any of Officer's
              duties, or any of Corporation's policies or procedures (including
              without limitation any such policies or procedures relating to
              conflicts of interests or standards of business conduct) or
              deliberate interference with the compliance by any other employee
              of Corporation with any of the foregoing;

       (ii)   The conviction of Officer for, or pleading by Officer of no
              contest (or similar plea) to, fraud, embezzlement,
              misappropriation of assets, malicious mischief, or any felony,
              other 


                                       4

<PAGE>

              than a crime for which vicarious liability is imposed upon
              Officer solely by reason of Officer's position with Corporation
              and not by reason of Officer's conduct;

       (iii)  Any other act, omission, event or condition constituting cause for
              the discharge of any employee under applicable law.

              Before terminating the Agreement pursuant to this Paragraph 
4.2(i), Corporation first shall have given Officer written notice specifying 
the nature of the breach, repudiation or failure to comply and thirty (30) 
days thereafter in which to cure such breach, repudiation or failure to 
comply, and Officer shall have failed to cure.  For purposes of this 
Paragraph 4.2, "Material" shall mean a breach, repudiation or failure that 
the Board determines has resulted in material injury to Corporation.

              4.3.   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 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. 

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 that is or may be competitive with 
the business of Corporation, directly or indirectly, whether or not for 
compensation, including, but not limited to, providing services similar to 
those provided by the Company; offering or soliciting or accepting an offer, 
to provide such services or taking any action to form, or become employed by, 
a firm or business to provide such services.

          if, after giving effect to such occurrence the Borrowers would be in
          compliance with all of their obligations and covenants relating to the

                International Swap Dealers Association, Inc.

                             MASTER AGREEMENT

                       dated as of August 31, 1998
                                   ---------------


  BankBoston, N.A.     and  Alexandria Real Estate Equities, Inc.  have 
- -----------------------     -------------------------------------- 
entered and/or anticipate entering into one or more transactions (each a 
"Transaction") that are or will be governed by this Master Agreement, which 
includes the schedule (the "Schedule"), and the documents and other 
confirming evidence (each a "Confirmation") exchanged between the parties 
confirming those Transactions.

Accordingly, the parties agree as follows: --

1.   INTERPRETATION

(a)  DEFINITIONS.  The terms defined in Section 14 and in the Schedule will 
have the meanings therein specified for the purpose of this Master Agreement.

(b)  INCONSISTENCY.  In the event of any inconsistency between the provisions 
of the Schedule and the other provisions of this Master Agreement, the 
Schedule will prevail. In the event of any inconsistency between the 
provisions of any Confirmation and this Master Agreement (including the 
Schedule), such Confirmation will prevail for the purpose of the relevant 
Transaction.

(c)  SINGLE AGREEMENT. All Transactions are entered into in reliance on the 
fact that this Master Agreement and all Confirmations form a single 
agreement between the parties (collectively referred to as this "Agreement"), 
and the parties would not otherwise enter into any Transactions.

2.   OBLIGATIONS

(a)  GENERAL CONDITIONS.

     (i)   Each party will make each payment or delivery specified in each 
     Confirmation to be made by it, subject to the other provisions of this 
     Agreement.

     (ii)  Payments under this Agreement will be made on the due date for 
     value on that date in the place of the account specified in the relevant 
     Confirmation or otherwise pursuant to this Agreement, in freely 
     transferable funds and in the manner customary for payments in the 
     required currency. Where settlement is by delivery (that is, other than 
     by payment), such delivery will be made for receipt on the due date in 
     the manner customary for the relevant obligation unless otherwise 
     specified in the relevant Confirmation or elsewhere in this Agreement.

     (iii)  Each obligation of each party under Section 2(a)(i) is subject to 
     (1) the condition precedent that no Event of Default or Potential Event 
     of Default with respect to the other party has occurred and is 
     continuing, (2) the condition precedent that no Early Termination Date 
     in respect of the relevant Transaction has occurred or been effectively 
     designated and (3) each other applicable condition precedent specified 
     in this Agreement.

(b)  CHANGE OF ACCOUNT.  Either party may change its account for receiving a 
payment or delivery by giving notice to the other party at least five Local 
Business Days prior to the scheduled date for the payment or delivery to 
which such change applies unless such other party gives timely notice of a 
reasonable objection to such change.

(c)  NETTING.  If on any date amounts would otherwise be payable: --

     (i)   in the same currency; and

     (ii)  in respect of the same Transaction,

by each party to the other, then, on such date, each party's obligation to 
make payment of any such amount will be automatically satisfied and 
discharged and, if the aggregate amount that would otherwise have been 
payable by one party exceeds the aggregate amount that would otherwise have 
been payable by the other party, replaced by an an obligation upon the party by 
whom the larger aggregate amount would have been payable to pay to the other 
party the excess of the larger aggregate amount over the smaller aggregate 
amount.

The parties may elect in respect of two or more Transactions that a net 
amount will be determined in respect of all amounts payable on the same date 
in the same currency in respect of such Transactions, regardless of whether 
such amounts are payable in respect of the same Transaction. The election may 
be made in the Schedule or a Confirmation by specifying that subparagraph 
(ii) above will not apply to the Transactions identified as being subject to 
the election, together with the starting date (in which case subparagraph 
(ii) above will not, or will cease to, apply to such Transactions from such 
date). This election may be made separately for different groups of 
Transactions and will apply separately to each pairing of Offices through 
which the parties make and receive payments or deliveries.

(d)  DEDUCTION OR WITHHOLDING FOR TAX.

     (i)  GROSS-UP.  All payments under this Agreement will be made without 
     any deduction or withholding for or on account of any Tax unless such 
     deduction or withholding is required by any applicable law, as modified 
     by the practice of any relevant governmental revenue authority, then in 
     effect. If a party is so required to deduct or withhold, then that party 
     ("X") will: --

          (1)  promptly notify the other party ("Y") of such requirement;

          (2)  pay to the relevant authorities the full amount required to be 
          deducted or withheld (including the full amount required to be 
          deducted or withheld from any additional amount paid by X to Y 
          under this Section 2(d)) promptly upon the earlier of determining 
          that such deduction or withholding is required or receiving notice 
          that such amount has been assessed against Y;

          (3)  promptly forward to Y an official receipt (or a certified 
          copy), or other documentation reasonably acceptable to Y, 
          evidencing such payment to such authorities; and

          (4)  if such Tax is an Indemnifiable Tax, pay to Y, in addition to 
          the payment to which Y is otherwise entitled under this Agreement, 
          such additional amount as is necessary to ensure that the net 
          amount actually received by Y (free and clear of Indemnifiable 
          Taxes, whether assessed against X or Y) will equal the full amount 
          Y would have received had no such deduction or withholding been 
          required. However, X will not be required to pay any additional 
          amount to Y to the extent that it would not be required to be paid 
          but for: --

               (A)  the failure by Y to comply with or perform any agreement 
               contained in Section 4(a)(i), 4(a)(iii) or 4(d); or

               (B)  the failure of a representation made by Y pursuant to 
               Section 3(f) to be accurate and true unless such failure would 
               not have occurred but for (I) any action taken by a taxing 
               authority, or brought in a court of competent jurisdiction, on 
               or after the date on which a Transaction is entered into 
               (regardless of whether such action is taken or brought with 
               respect to a party to this Agreement) or (II) a Change in 
               Tax Law.

     (ii)   LIABILITY, If: --

            (1)  X is required by any applicable law, as modified by the 
            practice of any relevant governmental revenue authority, to make 
            any deduction or withholding in respect of which X would not be 
            required to pay an additional amount to Y under Section 2(d)(i)(4);

            (2)  X does not so deduct or withhold; and

            (3)  a liability resulting from such Tax is assessed directly 
            against X,

     then, except to the extent Y has satisfied or then satisfies the 
     liability resulting from such Tax, Y will promptly 
     pay to X the amount of such liability (including any related 
     liability for interest, but including any related liability for 
     penalties only if Y has failed to comply with or perform any 
     agreement contained in Section 4(a)(i), 4(a)(iii) or 4(d)).

(e)  DEFAULT INTEREST; OTHER AMOUNTS.  Prior to the occurrence or 
effective designation of an Early Termination Date in respect of the relevant 
Transaction, a party that defaults in the performance of any payment 
obligation will, to the extent permitted by law and subject to Section 6(c), 
be required to pay interest (before as well as after judgment) on the overdue 
amount to the other party on demand in the same currency as such overdue 
amount, for the period from (and including) the original due date for payment 
to (but excluding) the date of actual payment, at the Default Rate. Such 
interest will be calculated on the basis of daily compounding and the actual 
number of days elapsed. If, prior to the occurrence or effective designation 
of an Early Termination Date in respect of the relevant Transaction, a party 
defaults in the performance of any obligation required to be settled by 
delivery, it will compensate the other party on demand if and to the extent 
provided for in the relevant Confirmation or elsewhere in this Agreement.

3.   REPRESENTATIONS

Each party represents to the other party (which representations will be deemed 
to be repeated by each party on each date on which a Transaction is entered 
into and, in the case of the representations in Section 3(f), at all times 
until the termination of this Agreement) that: --

(a)  BASIC REPRESENTATIONS.

     (i)   STATUS.  It is duly organised and validly existing under the laws 
     of the jurisdiction of its organisation or incorporation and, if

     perform its obligations under this Agreement and any obligations it has 
     under any Credit Support Document to which it is a party and has taken 
     all necessary action to authorise such execution, delivery and 
     performance;

     (iii)  NO VIOLATION OR CONFLICT.  Such execution, delivery and 
     performance do not violate or conflict with any law applicable to it, 
     any provision of its constitutional documents, any order or judgment of 
     any court or other agency of government applicable to it or any of its 
     assets or any contractual restriction binding on or affecting it or any 
     of its assets;

     (iv)  CONSENTS. All governmental and other consents that are required 
     to have been obtained by it with respect to this Agreement or any Credit 
     Support Document to which it is a party have been obtained and are in 
     full force and effect and all conditions of any such consents have been 
     complied with; and

     (v)   OBLIGATIONS BINDING. Its obligations under this Agreement and any 
     Credit Support Document to which it is a party constitute its legal, 
     valid and binding obligations, enforceable in accordance with their 
     respective terms (subject to applicable bankruptcy, reorganisation, 
     insolvency, moratorium or similar laws affecting creditors' rights 
     generally and subject, as to enforceability, to equitable principles of 
     general application (regardless of whether enforcement is sought in a 
     proceeding in equity or at law)).

      this Agreement or any applicable Credit Support Document without any 
      deduction or withholding for or on account of any Tax or with such 
      deduction or withholding at a reduced rate (so long as the completion, 
      execution or submission of such form or document would not materially 
      prejudice the legal or commercial position of the party in receipt of 
      such demand), with any such form or document to be accurate and 
      completed in a manner reasonably satisfactory to such other party and to 
      be executed and to be delivered with any reasonably required

Agreement or any Credit Support Document to which it is a party.

made by it under Section 3(f) to be accurate and true promptly upon learning

organised, managed and controlled, or considered to have its seat, or in 
which a branch or office through which it is acting for the purpose of this 
Agreement is located ("Stamp Tax Jurisdiction") and will indemnify the other 
party against any Stamp Tax levied or imposed upon the other party or in 
respect of the other party's execution or performance of this Agreement by 
any such Stamp Tax Jurisdiction which is not also a Stamp Tax Jurisdiction 
with respect to the other party.

5.  EVENTS OF DEFAULT AND TERMINATION EVENTS

(a)  EVENTS OF DEFAULT. The occurrence at any time with respect to a party 
or, if applicable, any Credit Support Provider of such party or any Specified 
Entity of such party of any of the following events constitutes an event of 
default (an "Event of Default") with respect to such party:--

     (i)   FAILURE TO PAY OR DELIVER.  Failure by the party to make, when due, 
     any payment under this Agreement or delivery under Section 2(a)(i) or 
     2(e) required to be made by it if such failure is not remedied on or 
     before the third Local Business Day after notice of such failure is given 
     to the party;

     (ii)   BREACH OF AGREEMENT.  Failure by the party to comply with or 
     perform any agreement or obligation (other than an obligation to make 
     any payment under this Agreement or delivery under Section 2(a)(i) or 
     2(e) or to give notice of a Termination Event or any agreement or 
     obligation under Section 4(a)(i), 4(a)(iii) or 4(d)) to be complied with 
     or performed by the party in accordance with this Agreement if such 
     failure is not remedied on or before the thirtieth day after notice of 
     such failure is given to the party;

     (iii)  CREDIT SUPPORT DEFAULT.

            (1)  Failure by the party or any Credit Support Provider of such 
            party to comply with or perform any agreement or obligation to 
            be complied with or performed by it in accordance with any Credit 
            Support Document if such failure is continuing after any 
            applicable grace period has elapsed;

            (2)  the expiration or termination of such Credit Support Document 
            or the failing or ceasing of such Credit Support Document to be in 
            full force and effect for the purpose of this Agreement (in either 
            case other than in accordance with its terms) prior to the 
            satisfaction of all obligations of such party under each 
            Transaction to which such Credit Support Document relates without 
            the written consent of the other party; or

            (3)  the party or such Credit Support Provider disaffirms, 
            disclaims, repudiates or rejects, in whole or in part, or 
            challenges the validity of, such Credit Support Document;

     (iv)   MISREPRESENTATION.  A representation (other than a representation 
     under Section 3(e) or (f)) made or repeated or deemed to have been made 
     or repeated by the party or any Credit Support Provider of such party in 
     this Agreement or any Credit Support Document proves to have been 
     incorrect or misleading in any material respect when made or repeated or 
     deemed to have been made or repeated;

     (v)    DEFAULT UNDER SPECIFIED TRANSACTION.  The party, any Credit 
     Support Provider of such party or any applicable Specified Entity of 
     such party (1) defaults under a Specified Transaction and, after giving 
     effect to any applicable notice requirement or grace period, there 
     occurs a liquidation of, an acceleration of obligations under, or any 
     early termination of, that Specified Transaction, (2) defaults, after 
     giving effect to any applicable notice requirement or grace period, in 
     making any payment or delivery due on the last payment, delivery or 
     exchange date of, or any payment on early termination of, a Specified 
     Transaction (or such default continues for at least three Local Business 
     Days if there is no applicable notice requirement or grace period) or 
     (3) disaffirms, disclaims, repudiates or rejects, in whole or in part, a 
     Specified Transaction (or such action is taken by any person or entity 
     appointed or empowered to operate it or act on its behalf);

     (vi)   CROSS DEFAULT.  If "Cross Default" is specified in the Schedule 
     as applying to the party, the occurrence or existence of (1) a default, 
     event of default or other similar condition or event (however

     described) in respect of such party, any Credit Support Provider of such 
     party or any applicable Specified Entity of such party under one or more 
     agreements or instruments relating to Specified Indebtedness of any of 
     them (individually or collectively) in an aggregate amount of not less 
     than the applicable Threshold Amount (as specified in the Schedule) 
     which has resulted in such Specified Indebtedness becoming, or becoming 
     capable at such time of being declared, due and payable under such 
     agreements or instruments, before it would otherwise have been due and 
     payable or (2) a default by such party, such Credit Support Provider or 
     such Specified Entity (individually or collectively) in making one or 
     more payments on the due date thereof in an aggregate amount of not less 
     than the applicable Threshold Amount under such agreements or 
     instruments (after giving effect to any applicable notice requirement 
     or grace period);

     (vii)  BANKRUPTCY.  The party, any Credit Support Provider of such party 
     or any applicable Specified Entity of such party:--

            (1) is dissolved (other than pursuant to a consolidation, 
            amalgamation or merger); (2) becomes insolvent or is unable to 
            pay its debts or fails or admits in writing its inability 
            generally to pay its debts as they become due; (3) makes a 
            general assignment, arrangement or composition with or for the 
            benefit of its creditors; (4) institutes or has instituted 
            against it a proceeding seeking a judgment of insolvency or 
            bankruptcy or any other relief under any bankruptcy or insolvency 
            law or other similar law affecting creditors' rights, or a 
            petition is presented for its winding-up or liquidation, and, in 
            the case of any such proceeding or petition instituted or 
            presented against it, such proceeding or petition (A) results in 
            a judgment of insolvency or bankruptcy or the entry of an order 
            for relief or the making of an order for its winding-up or 
            liquidation or (B) is not dismissed, discharged, stayed or 
            restrained in each case within 30 days of the institution or 
            presentation thereof; (5) has a resolution passed for its 
            winding-up, official management or liquidation (other than 
            pursuant to a consolidation, amalgamation or merger); (6) seeks 
            or becomes subject to the appointment of an administrator, 
            provisional liquidator, conservator, receiver, trustee, custodian 
            or other similar official for it or for all or substantially all 
            its assets; (7) has a secured party take possession of all or 
            substantially all its assets or has a distress, execution, 
            attachment, sequestration or other legal process levied, enforced 
            or sued on or against all or substantially all its assets and 
            such secured party maintains possession, or any such process is 
            not dismissed, discharged, stayed or restrained, in each case 
            within 30 days thereafter; (8) causes or is subject to any event 
            with respect to it which, under the applicable laws of any 
            jurisdiction, has an analogous effect to any of the events 
            specified in clauses (1) to (7) (inclusive); or (9) takes any 
            action in furtherance of, or indicating its consent to, approval 
            of, or acquiescence in, any of the foregoing acts; or

     (viii) MERGER WITHOUT ASSUMPTION.  The party or any Credit Support 
     Provider of such party consolidates or amalgamates with, or merges with 
     or into, or transfers all or substantially all its assets to, another 
     entity and, at the time of such consolidation, amalgamation, merger or 
     transfer:--

            (1)  the resulting, surviving or transferee entity fails to 
            assume all the obligations of such party or such Credit Support 
            Provider under this Agreement or any Credit Support Document to 
            which it or its predecessor was a party by operation of law or 
            pursuant to an agreement reasonably satisfactory to the other 
            party to this Agreement; or

            (2)  the benefits of any Credit Support Document fail to extend 
            (without the consent of the other party) to the performance by 
            such resulting, surviving or transferee entity of its obligations 
            under this Agreement.

(b)  TERMINATION EVENTS.  The occurrence at any time with respect to a party 
or, if applicable, any Credit Support Provider of such party or any Specified 
Entity of such party of any event specified below constitutes an Illegality 
if the event is specified in (i) below, a Tax Event if the event is specified 
in (ii) below or a Tax Event Upon Merger if the event is specified in (iii) 
below, and, if specified to be applicable, a Credit Event

<PAGE>

Upon Merger if the event is specified pursuant to (iv) below or an Additional 
Termination Event if the event is specified pursuant to (v) below:--

      (i)    ILLEGALITY. Due to the adoption of, or any change in, any 
      applicable law after the date on which a Transaction is entered into, or 
      due to the promulgation of, or any change in, the interpretation by any 
      court, tribunal or regulatory authority with competent jurisdiction of any
      applicable law after such date, it becomes unlawful (other than as a 
      result of a breach by the party of Section 4(b)) for such party (which 
      will be the Affected Party):--

             (1)    to perform any absolute or contingent obligation to make a 
             payment or delivery or to receive a payment or delivery in respect
             of such Transaction or to comply with any other material provision
             of this Agreement relating to such Transaction; or

             (2)    to perform, or for any Credit Support Provider of such party
             to perform, any contingent or other obligation which the party (or 
             such Credit Support Provider) has under any Credit Support Document
             relating to such Transaction;

      (ii)   TAX EVENT. Due to (x) any action taken by a taxing authority, or 
      brought in a court of competent jurisdiction, on or after the date on 
      which a Transaction is entered into (regardless of whether such action 
      is taken or brought with respect to a party to this Agreement) or (y) a 
      Change in Tax Law, the party (which will be the Affected Party) will, 
      or there is a substantial likelihood that it will, on the next 
      succeeding Scheduled Payment Date (1) be required to pay to the other 
      party an additional amount in respect of an Indemnifiable Tax under 
      Section 2(d)(i)(4) (except in respect of interest under Section 2(e), 
      6(d)(ii) or 6(e)) or (2) receive a payment from which an amount is 
      required to be deducted or withheld for or on account of a Tax (except 
      in respect of interest under Section 2(e), 6(d)(ii) or 6(e)) and no 
      additional amount is required to be paid in respect of such Tax under 
      Section 2(d)(1)(4) (other than by reason of Section 2(d)(i)(4)(A) or 
      (B));

      (iii)  TAX EVENT UPON MERGER. The party (the "Burdened Party") on 
      the next succeeding Scheduled Payment Date will either (1) be required 
      to pay an additional amount in respect of an Indemnifiable Tax under 
      Section 2(d)(i)(4) (except in respect of interest under Section 2(e), 
      6(d)(ii) or 6(e)) or (2) receive a payment from which an amount has 
      been deducted or withheld for or on account of any Indemnifiable Tax in 
      respect of which the other party is not required to pay an additional 
      amount (other than by reason of Section 2(d)(i)(4)(A) or (B)), in 
      either case as a result of a party consolidating or amalgamating with, 
      or merging with or into, or transferring all or substantially all its 
      assets to, another entity (which will be the Affected Party) where such 
      action does not constitute an event described in Section 5(a)(viii);

      (iv)   CREDIT EVENT UPON MERGER. If "Credit Event Upon Merger" is 
      specified in the Schedule as applying to the party, such party ("X"), 
      any Credit Support Provider of X or any applicable Specified Entity of 
      X consolidates or amalgamates with, or merges with or into, or 
      transfers all or substantially all its assets to, another entity and 
      such action does not constitute an event described in Section 
      5(a)(viii) but the creditworthiness of the resulting, surviving or 
      transferee entity is materially weaker than that of X, such Credit 
      Support Provider or such Specified Entity, as the case may be, 
      immediately prior to such action (and, in such event, X or its 
      successor or transferee, as appropriate, will be the Affected Party); or

      (v)    ADDITIONAL TERMINATION EVENT. If any "Additional Termination Event"
      is specified in the Schedule or any Confirmation as applying, the 
      occurrence of such event (and, in such event, the Affected Party or 
      Affected Parties shall be as specified for such Additional Termination 
      Event in the Schedule of such Confirmation).

(c)   EVENT OF DEFAULT AND ILLEGALITY. If an event or circumstance which 
would otherwise constitute or give rise to an Event of Default also 
constitutes an Illegality, it will be treated as an Illegality and will not 
constitute an Event of Default.

                                      7

6.    EARLY TERMINATION

(a)   RIGHT TO TERMINATE FOLLOWING EVENT OF DEFAULT. If at any time an Event 
of Default with respect to a party (the "Defaulting Party") has occurred and 
is then continuing, the other party (the "Non-defaulting Party") may, by not 
more than 20 days notice to the Defaulting Party specifying the relevant 
Event of Default, designate a day not earlier than the day such notice is 
effective as an Early Termination Date in respect of all outstanding 
Transactions. If, however, "Automatic Early Termination" is specified in the 
Schedule as applying to a party, then an Early Termination Date in respect of 
all outstanding Transactions will occur immediately upon the occurrence with 
respect to such party of an Event of Default specified in Section 
5(a)(vii)(1), (3), (5), (6) or, to the extent analogous thereto, (8), and as 
of the time immediately preceding the institution of the relevant proceeding 
or the presentation of the relevant petition upon the occurrence with respect 
to such party of an Event of Default specified in Section 5(a)(vii)(4) or, to 
the extent analogous thereto, (8).

(b)   RIGHT TO TERMINATE FOLLOWING TERMINATION EVENT.

      (i)    NOTICE. If a Termination Event occurs, an Affected Party will, 
      promptly upon becoming aware of it, notify the other party, specifying 
      the nature of that Termination Event and each Affected Transaction and 
      will also give such other information about that Termination Event as 
      the other party may reasonably require.

      (ii)   TRANSFER TO AVOID TERMINATION EVENT. If either an Illegality under
      Section 5(b)(i)(1) or a Tax Event occurs and there is only one Affected 
      Party, or if a Tax Event Upon Merger occurs and the Burdened Party is 
      the Affected Party, the Affected Party will, as a condition to its 
      right to designate an early Termination Date under Section 6(b)(iv), 
      use all reasonable efforts (which will not require such party to incur 
      a loss, excluding immaterial, incidental expenses) to transfer within 
      20 days after it gives notice under Section 6(b)(i) all its rights and 
      obligations under this Agreement in respect of the Affected 
      Transactions to another of its Offices or Affiliates so that such 
      Termination Event ceases to exist.

      If the Affected Party is not able to make such a transfer it will give 
      notice to the other party to that effect within such 20 day period, 
      whereupon the other party may effect such a transfer within 30 days 
      after the notice is given under Section 6(b)(i).

      Any such transfer by a party under this Section 6(b)(ii) will be 
      subject to and conditional upon the prior written consent of the other 
      party, which consent will not be withheld if such other party's 
      policies in effect at such time would permit it to enter into 
      transactions with the transferee on the terms proposed.

      (iii)  TWO AFFECTED PARTIES. If an Illegality under Section 
      5(b)(i)(1) or a Tax Event occurs and there are two Affected Parties, 
      each party will use all reasonable efforts to reach agreement within 30 
      days after notice thereof is given under Section 6(b)(i) on action to 
      avoid that Termination Event.

      (iv)   RIGHT TO TERMINATE, IF:--

             (1)    a transfer under Section 6(b)(ii) or an agreement under 
             Section (6)(b)(iii), as the case may be, has not been effected 
             with respect to all Affected Transactions within 30 days after 
             an Affected Party gives notice under Section 6(b)(i); or

             (2)    an Illegality under Section 5(b)(i)(2), a Credit Event Upon
             Merger or an Additional Termination Event occurs, or a Tax Event 
             Upon Merger occurs and the Burdened Party is not the Affected 
             Party,

      either party in the case of an Illegality, the Burdened Party in 
      the case of a Tax Event Upon Merger, any Affected Party in the case of 
      a Tax Event or an Additional Termination Event if there is more than 
      one Affected Party, or the party which is not the Affected Party in the 
      case of a Credit Event Upon Merger or an Additional Termination Event 
      if there is only one Affected Party may, by not more than 20 days 
      notice to the other party and provided that the relevant Termination 
      Event is then

                                      8

                                                ISDA -Registered Trademark- 1992
<PAGE>

     continuing, designate a day not earlier than the day such notice is 
     effective as an Early Termination Date in respect of all Affected 
     Transactions.

(c)  EFFECT OF DESIGNATION.

     (i)   If notice designating an Early Termination Date is given under 
     Section 6(a) or (b), the Early Termination Date will occur on the date so 
     designated, whether or not the relevant Event of Default or Termination 
     Event is then continuing.

     (ii)  Upon the occurrence or effective designation of an Early Termination 
     Date, no further payments or deliveries under Section 2(a)(i) or 2(e) in 
     respect of the Terminated Transactions will be required to be made, but 
     without prejudice to the other provisions of this Agreement.  The amount, 
     if any, payable in respect of an Early Termination Date shall be determined
     pursuant to Section 6(e).

(d)  CALCULATIONS.

     (i)   STATEMENT.  On or as soon as reasonably practicable following the 
     occurrence of an Early Termination Date, each party will make the 
     calculations on its part, if any, contemplated by Section 6(e) and will 
     provide to the other party a statement (1) showing, in reasonable detail, 
     such calculations (including all relevant quotations and specifying any 
     amount payable under Section 6(e)) and (2) giving details of the relevant 
     account to which any amount payable to it is to be paid.  In the absence 
     of written confirmation from the source of a quotation obtained in 
     determining a Market Quotation, the records of the party obtaining such 
     quotation will be conclusive evidence of the existence and accuracy of 
     such quotation.

     (ii)  PAYMENT DATE.  An amount calculated as being due in respect of any 
     Early Termination Date under Section 6(e) will be payable on the day that 
     notice of the amount payable is effective (in the case of an Early 
     Termination Date which is designated or occurs as a result of an Event of 
     Default) and on the day which is two Local Business Days after the day on 
     which notice of the amount payable is effective (in the case of an Early 
     Termination Date which is designated as a result of a Termination Event).  
     Such amount will be paid together with (to the extent permitted under 
     applicable law) interest thereon (before as well as after judgment) in the 
     Termination Currency, from (and including) the relevant Early Termination 
     Date to (but excluding) the date such amount is paid, at the Applicable 
     Rate. Such interest will be calculated on the basis of daily compounding 
     and the actual number of days elapsed.

(e)  PAYMENTS ON EARLY TERMINATION.  If an Early Termination Date occurs, the 
following provisions shall apply based on the parties' election in the Schedule 
of a payment measure, either "Market Quotation" or "Loss", and a payment 
method, either the "First Method" or the "Second Method".  If the parties fail 
to designate a payment measure or payment method in the Schedule, it will be 
deemed that "Market Quotation" or the "Second Method", as the case may be, 
shall apply.  The amount, if any, payable in respect of an Early Termination 
Date and determined pursuant to this Section will be subject to any Set-off.

     (i)   EVENTS OF DEFAULT.  If the Early Termination Date results from an 
     Event of Default:--

           (1)   FIRST METHOD AND MARKET QUOTATION.  If the First Method and 
           Market Quotation apply, the Defaulting Party will pay to the 
           Non-defaulting Party the excess, if a positive number, of (A) the 
           sum of the Settlement Amount (determined by the Non-defaulting Party)
           in respect of the Terminated Transactions and the Termination 
           Currency Equivalent of the Unpaid Amounts owing to the Non-defaulting
           Party over (B) the Termination Currency Equivalent of the Unpaid 
           Amounts owing to the Defaulting Party.

           (2)   FIRST METHOD AND LOSS.  If the First Method and Loss apply, the
           Defaulting Party will pay to the Non-defaulting Party, if a positive 
           number, the Non-defaulting Party's Loss in respect of this Agreement.

           (3)   SECOND METHOD AND MARKET QUOTATION.  If the Second Method and 
           Market Quotation apply, an amount will be payable equal to (A) the 
           sum of the Settlement Amount (determined by the


                                       9

                                                ISDA -Registered Trademark- 1992
<PAGE>

           Non-defaulting Party) in respect of the Terminated Transactions and 
           the Termination Currency Equivalent of the Unpaid Amounts owing to 
           the Non-defaulting Party less (B) the Termination Currency Equivalent
           of the Unpaid Amounts owing to the Defaulting Party.  If that amount
           is a positive number, the Defaulting Party will pay it to the 
           Non-defaulting Party; if it is a negative number, the Non-defaulting 
           Party will pay the absolute value of that amount to the Defaulting 
           Party.

           (4)   SECOND METHOD AND LOSS.  If the Second Method and Loss apply, 
           an amount will be payable equal to the Non-defaulting Party's Loss in
           respect of this Agreement.  If that amount is a positive number, the 
           Defaulting Party will pay it to the Non-defaulting Party; if it is a 
           negative number, the Non-defaulting Party will pay the absolute value
           of that amount to the Defaulting Party.

     (ii)  TERMINATION EVENTS.  If the Early Termination Date results from a 
     Termination Event:--

           (1)   ONE AFFECTED PARTY.  If there is one Affected Party, the amount
           payable will be determined in accordance with Section 6(e)(i)(3), if 
           Market Quotation applies, or Section 6(e)(i)(4), if Loss applies, 
           except that, in either case, references to the Defaulting Party and 
           to the Non-defaulting Party will be deemed to be references to the 
           Affected Party and the party which is not the Affected Party, 
           respectively, and, if Loss applies and fewer than all the 
           Transactions are being terminated, Loss shall be calculated in 
           respect of all Terminated Transactions.

           (2)   TWO AFFECTED PARTIES.  If there are two Affected Parties:--

                 (A)  if Market Quotation applies, each party will determine a 
                 Settlement Amount in respect of the Terminated Transactions, 
                 and an amount will be payable equal to (I) the sum of (a) 
                 one-half of the difference between the Settlement Amount of the
                 party with the higher Settlement Amount ("X") and the 
                 Settlement Amount of the party with the lower Settlement Amount
                 ("Y") and (b) the Termination Currency Equivalent of the Unpaid
                 Amounts owing to X less (II) the Termination Currency 
                 Equivalent of the Unpaid Amounts owing to Y; and

                 (B)  if Loss applies, each party will determine its Loss in 
                 respect of this Agreement (or, if fewer than all the 
                 Transactions are being terminated, in respect of all 
                 Terminated Transactions) and an amount will be payable equal 
                 to one-half of the difference between the Loss of the party 
                 with the higher Loss ("X") and the Loss of the party with the 
                 lower Loss ("Y").

           If the amount payable is a positive number, Y will pay it to X; if 
           it is a negative number, X will pay the absolute value of that amount
           to Y.

     (iii) ADJUSTMENT FOR BANKRUPTCY.  In circumstances where an Early 
     Termination Date occurs because "Automatic Early Termination" applies in 
     respect of a party, the amount determined under this Section 6(e) will be 
     subject to such adjustments as are appropriate and permitted by law to 
     reflect any payments or deliveries made by one party to the other under 
     this Agreement (and retained by such other party) during the period from 
     the relevant Early Termination Date to the date for payment determined 
     under Section 6(d)(ii).

     (iv)  PRE-ESTIMATE.  The parties agree that if Market Quotation applies an 
     amount recoverable under this Section 6(e) is a reasonable pre-estimate of 
     loss and not a penalty.  Such amount is payable for the loss of bargain 
     and the loss of protection against future risks and except as otherwise 
     provided in this Agreement neither party will be entitled to recover any 
     additional damages as a consequence of such losses.

7.  TRANSFER

Subject to Section 6(b)(ii), neither this Agreement nor any interest or 
obligation in or under this Agreement may be transferred (whether by way of 
security or otherwise) by either party without the prior written consent of 
the other party, except that:--

(a)  a party may make such a transfer of this Agreement pursuant to a 
consolidation or amalgamation with, or merger with or into, or transfer of 
all or substantially all its assets to, another entity (but without prejudice 
to any other right or remedy under this Agreement); and

(b)  a party may make such a transfer of all or any part of its interest in 
any amount payable to it from a Defaulting Party under Section 6(e).

Any purported transfer that is not in compliance with this Section will be 
void.

8.  CONTRACTUAL CURRENCY

(a)  PAYMENT IN THE CONTRACTUAL CURRENCY.  Each payment under this Agreement 
will be made in the relevant currency specified in this Agreement for that 
payment (the "Contractual Currency"). To the extent permitted by applicable 
law, any obligation to make payments under this Agreement in the Contractual 
Currency will not be discharged or satisfied by any tender in any currency 
other than the Contractual Currency, except to the extent such tender results 
in the actual receipt by the party to which payment is owed, acting in a 
reasonable manner and in good faith in converting the currency so tendered 
into the Contractual Currency, of the full amount in the Contractual Currency 
of all amounts payable in respect of this Agreement. If for any reason the 
amount in the Contractual Currency so received falls short of the amount in 
the Contractual Currency payable in respect of this Agreement, the party 
required to make the payment will, to the extent permitted by applicable law, 
immediately pay such additional amount in the Contractual Currency as may be 
necessary to compensate for the shortfall. If for any reason the amount in 
the Contractual Currency so received exceeds the amount in the Contractual 
Currency payable in respect of this Agreement, the party receiving the 
payment will refund promptly the amount of such excess.

(b)  JUDGMENTS.  To the extent permitted by applicable law, if any judgment 
or order expressed in a currency other than the Contractual Currency is 
rendered (i) for the payment of any amount owing in respect of this 
Agreement, (ii) for the payment of any amount relating to any early 
termination in respect of this Agreement or (iii) in respect of a judgment or 
order of another court for the payment of any amount described in (i) or (ii) 
above, the party seeking recovery, after recovery in full of the aggregate 
amount to which such party is entitled pursuant to the judgment or order, 
will be entitled to receive immediately from the other party the amount of 
any shortfall of the Contractual Currency received by such party as a 
consequence of sums paid in such other currency and will refund promptly to 
the other party any excess of the Contractual Currency received by such 
party as a consequence of sums paid in such other currency if such 
shortfall or such excess arises or results from any variation between the 
rate of exchange at which the Contractual Currency is converted into the 
currency of the judgment or order for the purposes of such judgment or order 
and the rate of exchange at which such party is able, acting in a reasonable 
manner and in good faith in converting the currency received into the 
Contractual Currency, to purchase the Contractual Currency with the amount of 
the currency of the judgment or order actually received by such party. The 
term "rate of exchange" includes, without limitation, any premiums and costs 
of exchange payable in connection with the purchase of or conversion into the 
Contractual Currency.

(e)  SEPARATE INDEMNITIES.  To the extent permitted by applicable law, these 
indemnities constitute separate and independent obligations from the other 
obligations in this Agreement, will be enforceable as separate and 
independent causes of action, will apply notwithstanding any indulgence 
granted by the party to which any payment is owed and will not be affected by 
judgment being obtained or claim or proof being made for any other sums 
payable in respect of this Agreement.

(d)  EVIDENCE OF LOSS.  For the purpose of this Section 8, it will be 
sufficient for a party to demonstrate that it would have suffered a loss had 
an actual exchange or purchase been made.

9.   MISCELLANEOUS

(a)  ENTIRE AGREEMENT.  This Agreement constitutes the entire agreement and 
understanding of the parties with respect to its subject matter and 
supersedes all oral communication and prior writings with respect thereto.

(b)  AMENDMENTS.  No amendment, modification or waiver in respect of this 
Agreement will be effective unless in writing (including a writing evidenced 
by a facsimile transmission) and executed by each of the parties or confirmed 
by an exchange of telexes or electronic messages on an electronic messaging 
system.

(c)  SURVIVAL OF OBLIGATIONS.  Without prejudice to Sections 2(a)(iii) and 
6(c)(ii), the obligations of the parties under this Agreement will survive 
the termination of any Transaction.

(d)  REMEDIES CUMULATIVE.  Except as provided in this Agreement, the rights, 
powers, remedies and privileges provided in this Agreement are cumulative and 
not exclusive of any rights, powers, remedies and privileges provided by law.

(e)  COUNTERPARTS AND CONFIRMATIONS.

     (i)   This Agreement (and each amendment, modification and waiver in 
     respect of it) may be executed and delivered in counterparts (including 
     by facsimile transmission), each of which will be deemed an original.

     (ii)  The parties intend that they are legally bound by the terms of 
     each Transaction from the moment they agree to those terms (whether 
     orally or otherwise). A Confirmation shall be entered into as soon as 
     practicable and may be executed and delivered in counterparts 
     (including by facsimile transmission) or be created by an exchange of 
     telexes or by an exchange of electronic messages on an electronic 
     messaging system, which in each case will be sufficient for all purposes 
     to evidence a binding supplement to this Agreement. The parties will 
     specify therein or through another effective means that any such 
     counterpart, telex or electronic message constitutes a Confirmation.

(f)  NO WAIVER OF RIGHTS:  A failure or delay in exercising any right, power 
or privilege in respect of this Agreement will not be presumed to operate as 
a waiver, and a single or partial exercise of any right, power or privilege 
will not be presumed to preclude any subsequent or further exercise, of that 
right, power or privilege or the exercise of any other right, power or 
privilege.

(g)  HEADINGS.  The headings used in this Agreement are for convenience of 
reference only and are not to affect the construction of or to be taken into 
consideration in interpreting this Agreement.

10.  OFFICES; MULTIBRANCH PARTIES

(a)  If Section 10(a) is specified in the Schedule as applying, each party 
that enters into a Transaction through an Office other than its head or home 
office represents to the other party that, notwithstanding the place of 
booking office or jurisdiction of incorporation or organisation of such 
party, the obligations of such party are the same as if it had entered into 
the Transaction through its head or home office. This representation will be 
deemed to be repeated by such party on each date on which a Transaction is 
entered into.

(b)  Neither party may change the Office through which it makes and receives 
payments or deliveries for the purpose of a Transaction without the prior 
written consent of the other party.

(c)  If a party is specified as a Multibranch Party in the Schedule, such 
Multibranch Party may make and receive payments or deliveries under any 
Transaction through any Office listed in the Schedule, and the Office through 
which it makes and receives payments or deliveries with respect to a 
Transaction will be specified in the relevant Confirmation.

11.  EXPENSES

A Defaulting Party will, on demand, indemnify and hold harmless the other 
party for and against all reasonable out-of-pocket expenses, including legal 
fees and Stamp Tax, incurred by such other party by reason of the enforcement 
and protection of its rights under this Agreement or any Credit Support 
Document

to which the Defaulting Party is a party or by reason of the early 
termination of any Transaction, including, but not limited to, costs of

(b)  CHANGE OF ADDRESSES.  Either party may by notice to the other change the 
address, telex or facsimile number or electronic messaging system details at 
which notices or other communications are to be given to it.

13.  GOVERNING LAW AND JURISDICTION

(a)  GOVERNING LAW.  This Agreement will be governed by and construed in 
accordance with the law specified in the Schedule.

(b)  JURISDICTION.  With respect to any suit, action or proceedings relating 
to this Agreement ("Proceedings"), each party irrevocably:--

     (i)    submits to the jurisdiction of the English courts, if this 
     Agreement is expressed to be governed by English law, or to the 
     non-exclusive jurisdiction of the courts of the State of New York and 
     the United States District Court located in the Borough of Manhattan in 
     New York City, if this Agreement is expressed to be governed by the laws 
     of the State of New York; and

     (ii)   waives any objection which it may have at any time to the laying 
     of venue of any Proceedings brought in any such court, waives any claim 
     that such Proceedings have brought in an inconvenient forum and further 
     waives the right to object, with respect to such Proceedings, that such 
     court does not have any jurisdiction over such party.

Nothing in this Agreement precludes either party from bringing Proceedings in 
any other jurisdiction (outside, if this Agreement is expressed to be 
governed by English law, the Contracting States, as defined in Section 1(3) 
of the Civil Jurisdiction and Judgments Act 1982 or any modification, 
extension or re-enactment thereof for the time being in force) nor will the 
bringing of Proceedings in any one or more jurisdictions preclude the 
bringing of Proceedings in any other jurisdiction.

(c)  SERVICE OF PROCESS.  Each party irrevocably appoints the Process Agent 
(if any) specified opposite its name in the Schedule to receive, for it and 
on its behalf, service of process in any Proceedings. If for any

                                      13

<PAGE>

reason any party's Process Agent is unable to act as such, such party will 
promptly notify the other party and within 30 days appoint a substitute 
process agent acceptable to the other party. The parties irrevocably consent 
to service of process given in the manner provided for notices in Section 12. 
Nothing in this Agreement will affect the right of either party to serve 
process in any other manner permitted by law.

(d)  WAIVER OF IMMUNITIES.  Each party irrevocably waives, to the fullest 
extent permitted by applicable law, with respect to itself and its revenues 
and assets (irrespective of their use or intended use), all immunity on 
the grounds of sovereignty or other similar grounds from (i) suit, (ii) 
jurisdiction of any court, (iii) relief by way of injunction, order for 
specific performance or for recovery of property, (iv) attachment of its 
assets (whether before or after judgment) and (v) execution or enforcement of 
any judgment to which it or its revenues or assets might otherwise be 
entitled in any Proceedings in the courts of any jurisdiction and irrevocably 
agrees, to the extent permitted by applicable law, that it will not claim any 
such immunity in any Proceedings.

"LOSS" means, with respect to this Agreement or one or more Terminated 
Transactions, as the case may be, and a party, the Termination Currency 
Equivalent of an amount that party reasonably determines in good faith to be 
its total losses and costs (or gain, in which case expressed as a negative 
number) in connection with this Agreement or that Terminated Transaction or 
group of Terminated Transactions, as the case may be, including any loss of 
bargain, cost of funding or, at the election of such party but without 
duplication, loss or cost incurred as a result of its terminating, 
liquidating, obtaining or reestablishing any hedge or related trading 
position (or any gain resulting from any of them). Loss includes losses and 
costs (or gains) in respect of any payment or delivery required to have been 
made (assuming satisfaction of each applicable condition precedent) on or 
before the relevant Early Termination Date and not made, except, so as to 
avoid duplication, if Section 6(e)(i)(1) or (3) or 6(e)(ii)(2)(A) applies. 
Loss does not include a party's legal fees and out-of-pocket expenses 
referred to under Section 11. A party will determine its Loss as of the 
relevant Early Termination Date, or, if that is not reasonably practicable, 
as of the earliest date thereafter as is reasonably practicable. A party may 
(but need not) determine its Loss by reference to quotations of relevant 
rates or prices from one or more leading dealers in the relevant markets.

"MARKET QUOTATION" means, with respect to one or more Terminated Transactions 
and a party making the determination, an amount determined on the basis of 
quotations from Reference Market-makers. Each quotation will be for an 
amount, if any, that would be paid to such party (expressed as a negative 
number) or by such party (expressed as a positive number) in consideration of 
an agreement between such party (taking into account any existing Credit 
Support Document with respect to the obligations of such party) and the 
quoting Reference Market-maker to enter into a transaction (the "Replacement 
Transaction") that would have the effect of preserving for such party the 
economic equivalent of any payment or delivery (whether the underlying 
obligation was absolute or contingent and assuming the satisfaction of each 
applicable condition precedent) by the parties under Section 2(a)(i) in 
respect of such Terminated Transaction or group of Terminated Transactions 
that would, but for the occurrence of the relevant Early Termination Date, 
have
                                      15

                                                ISDA -Registered Trademark- 1992
<PAGE>

been required after that date. For this purpose, Unpaid Amounts in respect of 
the Terminated Transaction or group of Terminated Transactions are to be 
excluded but, without limitation, any payment or delivery that would, but for 
the relevant Early Termination Date, have been required (assuming 
satisfaction of each applicable condition precedent) after that Early 
Termination Date is to be included. The Replacement Transaction would be 
subject to such documentation as such party and the Reference Market-maker 
may, in good faith, agree. The party making the determination (or its agent) 
will request each Reference Market-maker to provide its quotation to the 
extent reasonably practicable as of the same day and time (without regard to 
different time zones) on or as soon as reasonably practicable after the 
relevant Early Termination Date. The day and time as of which those 
quotations are to be obtained will be selected in good faith by the party 
obliged to make a determination under Section 6(e), and, if each party is so 
obliged, after consultation with the other. If more than three quotations are 
provided, the Market Quotation will be the arithmetic mean of the quotations, 
without regard to the quotations having the highest and lowest values. If 
exactly three such quotations are provided, the Market Quotation will be the 
quotation remaining after disregarding the highest and lowest quotations. For 
this purpose, if more than one quotation has the same highest value or lowest 
value, then one of such quotations shall be disregarded. If fewer than three 
quotations are provided, it will be deemed that the Market Quotation in 
respect of such Terminated Transaction or group of Terminated Transactions 
cannot be determined.

"NON-DEFAULT RATE" means a rate per annum equal to the cost (without proof or 
evidence of any actual cost) to the Non-defaulting Party (as certified by it) 
if it were to fund the relevant amount.

among dealers of the highest credit standing which satisfy all the criteria 
that such party applies generally at the time in deciding whether to offer or

such dealers having an office in the same city.

"RELEVANT JURISDICTION" means, with respect to a party, the jurisdictions (a) 
in which the party is incorporated, organised, managed and controlled or 
considered to have its seat, (b) where an Office through which the party is 
acting for purposes of this Agreement is located, (c) in which the party 
executes this Agreement and (d) in relation to any  payment, from or through 
which such payment is made.

"SCHEDULED PAYMENT DATE" means a date on which a payment or delivery is to be 
made under Section 2(a)(i) with respect to a Transaction.

amount under Section 6 is entitled or subject (whether arising under this 
Agreement, another contract, applicable law or otherwise) that is exercised 
by, or imposed on, such payer.

"SETTLEMENT AMOUNT" means, with respect to a party and any Early Termination 
Date, the sum of:--

(a)  the Termination Currency Equivalent of the Market Quotations (whether 
positive or negative) for each Terminated Transaction or group of Terminated 
Transactions for which a Market Quotation is determined; and

(b)  such party's Loss (whether positive or negative and without reference to 
any Unpaid Amounts) for each Terminated Transaction or group of Terminated 
Transactions for which a Market Quotation cannot be determined or would not 
(in the reasonable belief of the party making the determination) produce a 
commercially reasonable result.

"SPECIFIED ENTITY" has the meaning specified in the Schedule.

reasonably determined by both parties.

     inserted at the end thereof:

     "; provided, however, that notwithstanding the foregoing, an Event of
     Default shall not occur under either (1) or (2) above, if (a) the event or
     condition referred to in (1) or the failure to pay referred to in (2) is a
     failure to pay caused by an error or omission of an administrative or
     operational nature, (b) funds were available to such party to enable it to
     make the relevant payment when due, and (c) such relevant payment is made
     within three Local Business Days following receipt of written notice from
     an interested party of such failure to pay".

     disaster, armed conflict, act of terrorism, riot, labor disruption or any
     other circumstance beyond its control after the date on which a Transaction

     misconduct) for such a party (which will be the Affected Party):

          (x)  to perform any absolute or contingent obligation, to make a
     payment or delivery or to receive a payment or delivery in respect of such

     contemplated by, the Credit Agreement shall have expired or been terminated

      (i) The definitions listed above shall be added to Section 14 of the
          Agreement in alphabetical order.

PART 5.   OTHER PROVISIONS.

(a)  SET-OFF.

     Any amount (the "EARLY TERMINATION AMOUNT") payable to one party (the
     Payee) by the other party (the Payer) under Section 6(e), in circumstances
     where there is a Defaulting Party or one Affected Party in the case where a
     Termination Event under Section 5(b)(iv) has occurred, will, at the option
     of the party ("X") other than the Defaulting Party or the Affected Party
     (and without prior notice to the Defaulting Party or the Affected Party),
     be reduced by its set-off against any amount(s) (the "Other Agreement
     Amount") payable (whether at such time or in the

                                       6
<PAGE>

     future or upon the occurrence of a contingency) by the Payee to the 
     Payer (irrespective of the currency, place of payment or booking office 
     of the obligation) under any other agreement(s) between the Payee and 
     the Payer or instrument(s) or undertaking(s) issued or executed by one 
     party to, or in favor of, the other party (and the Other Agreement 
     Amount will be discharged promptly and in all respects to the extent it 
     is so set-off).  X will give notice to the other party of any set-off 
     effected under this Section 5(a).

     For this purpose, either the Early Termination Amount or the Other
     Agreement Amount (or the relevant portion of such amounts) may be converted
     by X into the currency in which the other is denominated at the rate of
     exchange at which such party would be able, acting in a reasonable manner
     and in good faith, to purchase the relevant amount of such currency.

     If an obligation is unascertained, X may in good faith estimate that
     obligation and set-off in respect of the estimate, subject to the relevant
     party accounting to the other when the obligation is ascertained.

     Nothing in this Section 5(a) shall be effective to create a charge or other
     security interest.  This Section 5(a) shall be without prejudice and in
     addition to any right of set-off, combination of accounts, lien or other
     right to which any party is at any time otherwise entitled (whether by
     operation of law, contract or otherwise).

(b)  DEFINITIONS.

     the provisions of this Agreement and the Definitions, this Agreement will
     prevail.  In the event of any inconsistency between the provisions of any
     Confirmation and this Agreement, such Confirmation will prevail for the
     purpose of the relevant Transaction.

     (ii) With effect from and including the date of this Agreement (A) any
     reference to a "Swap Transaction" in the Definitions is deemed to be a
     reference to a "Transaction" for the purpose of interpreting this Agreement
     or any Confirmation and (B) any reference to a "Transaction" in this
     Agreement or any Confirmation is deemed to be a reference to a "Swap
     Transaction" for the purpose of interpreting the Definitions.

     (h)  It is an "eligible swap participant" within the meaning of CFTC
     Regulations Section 35.1(b)(2).

     (i)  Neither this Agreement nor any Transaction is one of a fungible class
     of agreements that are standardized as to their material economic terms,
     within the meaning of CFTC Regulations Section 35.2(b).

     (j)  The creditworthiness of the other party was or will be a material
     consideration in entering into or determining the terms of this Agreement
     and each Transaction, including pricing, cost or credit enhancement terms
     of the Agreement or Transaction, within the meaning of CFTC Regulations
     Section 35.2(c).

     (k)  It has entered into this Agreement (including each Transaction
     evidenced hereby) in conjunction with its line of business (including
     financial intermediation services) or the financing of its business.

     (l)  It engages, will engage and holds itself out as engaging in "financial
     contracts", as defined in Regulation EE of the Federal Reserve Board, as a
     counterparty on both sides of one or more "financial markets" (as defined
     in such regulation) and it fulfills at least one of the quantitative tests
     contained in such regulation.

     (m)  RELATIONSHIP BETWEEN PARTIES.  Each party will be deemed to represent
     to the other party on the date on which it enters into a Transaction that
     (absent a written agreement between the parties that expressly imposes
     affirmative obligations to the contrary for the Transaction):

           (i) NON-RELIANCE.  It is acting for its own account, and it has made
     its own independent decisions to enter into that Transaction and as to
     whether that Transaction is appropriate or proper for it based upon its own
     judgment and upon advice from such advisors as it has deemed necessary.  It
     is not relying on any communication (written or oral) of the other party as
     investment advice or as a recommendation to enter into that Transaction; 
     it being understood that information and explanations related to the terms
     and conditions of a Transaction shall not be considered investment advice
     or a recommendation to enter into that Transaction.  It has not received
     from the other party any assurance or guarantee as to the expected results
     of that Transaction.

          (ii) ASSESSMENT AND UNDERSTANDING.  It is capable of assessing the
     merits of and understanding (on its own behalf or through independent
     professional advice), and understands and accepts, the terms, conditions
     and risks of that Transaction.  It is also capable of assuming, and
     assumes, the risks of that Transaction.

                                       8
<PAGE>

         (iii) STATUS OF PARTIES. The other party is not acting as a
     fiduciary for or as an advisor to it in respect of that Transaction.

(e)  RECORDING.

     Each party hereto consents to the monitoring or recording, at any time and
     from time to time, by the other party of any and all communications between
     officers or employees of the parties, waives any further notice of such
     monitoring or recording, and agrees to notify its officers and employees of
     such monitoring or recording.

(f)  NEGATIVE INTEREST RATES.

     (i)  Floating Amounts.  "Swap Transaction" means, for the purposes of this
     provision concerning Negative Interest Rates, a rate exchange or swap
     transaction, including transactions involving a single currency or two or
     more currencies.  Party A and Party B agree that, if with respect to a
     Calculation Period for a Swap Transaction either party is obligated to pay
     a Floating Amount that is a negative number (either due to a quoted
     negative Floating Rate or by operation of a Spread that is subtracted from
     the Floating Rate), the Floating Amount with respect to that party for that
     Calculation Period will be deemed to be zero, and the other party will pay
     to that party the absolute value of the negative Floating Amount as
     calculated, in addition to any amounts otherwise owed by the other party
     for that Calculation Period with respect to that Swap Transaction, on the
     Payment Date that the Floating Amount would have been due if it had been a
     positive number.  Any amounts paid by the other party with respect to the
     absolute value of a negative Floating Amount will be paid to such account
     as the receiving party may designate (unless such other party gives timely
     notice of a reasonable objection to such designation) in the currency in
     which that Floating Amount would have been paid if it had been a positive
     number (and without regard to the currency in which the other party is
     otherwise obligated to make payments).  

     (ii) Compounding.  Party A and Party B agree that, if with respect to one
     or more Compounding Periods for a Swap Transaction where "Compounding" or
     "Flat Compounding" is specified to be applicable, the Compounding Period
     Amount, the Basic Compounding Period Amount or the Additional Compounding
     Period Amount is a negative number (either due to a quoted negative
     Floating Rate or by operation of a Spread that is subtracted from the
     Floating Rate), then the Floating Amount for the Calculation Period in
     which that Compounding Period or those Compounding Periods occur will be
     either the sum of all the Compounding Period Amounts or the sum of all the
     Basic Compounding Period Amounts and all the Additional Compounding Period
     Amounts in that Calculation Period (whether positive or negative).  If such
     sum is positive, then the Floating Rate Payer with respect to the Floating
     Amount so calculated will pay that Floating Amount to the other party.  If
     such sum is negative, the Floating Amount with respect to the party that
     would be obligated to pay that Floating Amount will be deemed to be zero,
     and the other party will pay to that party the absolute value of the
     negative Floating Amount as calculated, such payment to be made in
     accordance with (i) above.

will be governed by this Agreement.  Any forward rate agreement into which the
parties may enter and in respect of which the confirmation or other confirming
