             Notes to Condensed Consolidated Financial Statements
                                  (Unaudited)


1. BACKGROUND AND BASIS OF PRESENTATION

BACKGROUND

Alexandria Real Estate Equities, Inc., a Maryland corporation (the 
"Company"), was formed in October 1994 to acquire, manage, and selectively 
develop properties for lease principally to the life science industry ("Life 
Science Facilities"). As of June 30, 1998 and December 31, 1997, the Company 
owned 41 and 22 Life Science Facilities, respectively.

The accompanying interim financial statements have been prepared by the
Company's management in accordance with generally accepted accounting
principles and in conformity with the rules and regulations of the Securities
and Exchange Commission. In the opinion of management, the interim financial
statements presented herein reflect all adjustments of a normal and recurring
nature that are necessary to fairly state the interim financial statements. The
results of operations for the interim period are not necessarily indicative of
the results that may be expected for the year ended December 31, 1998. These
financial statements should be read in conjunction with the financial
statements included in the Company's Annual Report on Form 10-K for the year
ended December 31, 1997.

BASIS OF PRESENTATION

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

RECLASSIFICATIONS

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

                                               ----------      --------
</TABLE>

During the six months ended June 30, 1998, the Company acquired 19 Life Science
Facilities from various unrelated third parties for an aggregate purchase price
(including closing and transaction costs) of $145,345,000.

3. SECURED NOTE RECEIVABLE

In connection with the acquisition of a Life Science Facility in San Diego,
California in March 1998, the Company 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, the Company may obtain
title to the improvements that secure the loan, and, in such event, the Company
may also require the sole tenant at the property to lease such improvements
back from the Company for an additional rental amount.

4. UNSECURED LINE OF CREDIT

The Company has an unsecured line of credit providing for borrowings of up to
$150,000,000.  Borrowings under the line of credit bear interest at a floating
rate based on the Company's election of either a LIBOR based rate or the higher
of the bank's reference rate and the Federal Funds rate plus 0.5%.  For each
LIBOR based advance, the Company must elect to fix the rate for a period of
one, two, three or six months.


                                       8
<PAGE>

4. 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 the Company
acquires additional unencumbered properties, borrowings available under the
line of credit will increase.  As of June 30, 1998, borrowings under the line
of credit were limited to approximately $150,000,000, and $110,200,000 was
outstanding (leaving $39,800,000 available) at a weighted average interest rate
of 7.16%.

The line of credit expires May 31, 2000 and provides for annual extensions
(provided there is no default) for one-year periods upon notice by the Company
and consent of the participating banks. 


In August 1998, the Company amended its unsecured line of credit to provide 
for borrowings of up to $250 million.  As under the original line, borrowings 
under the line of credit, as amended, bear interest at a floating rate based 
on the Company's election of either a LIBOR based rate or the higher of the 
bank's reference rate and the Federal Funds rate plus 0.5%. However, under 
the line, as amended, the LIBOR based rate has been reduced, resulting in a 
rate of 6.91% as of August 5, 1998.  Financial covenants for the line of 
credit, as amended, are substantially similar to those under the original 
line.  The line, as amended, 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.

5. SECURED NOTES PAYABLE

As of June 30, 1998, the Company had five notes payable to certain banks and an
insurance company, secured by first deeds of trust on eight Life Science
Facilities.  The notes bear interest at fixed rates ranging from 7.17% to 9.00%
and are due at various dates through 2016.

6.  STOCKHOLDERS EQUITY

On May 29, 1998, the Company sold 1,150,000 shares of 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).  The aggregate proceeds 
to the Company, net of offering costs of $1.9 million, were approximately 
$33.2 million.

On June 1, 1998, the Company declared a cash dividend on its common stock of
$5,022,000 ($ 0.40 per share) for the calendar quarter ended June 30, 1998. The
dividend was paid on July 17, 1998.

7.  COMMITMENTS

The Company is committed to complete the construction of a building and 
certain improvements thereto in San Diego, California at a remaining cost of 
approximately $4.8 million under the terms of two leases.  In addition, the 
Company is committed to complete the construction of a building and certain 
improvements thereto in Gaithersburg, Maryland at a remaining cost of between 
$9.1 million and $18.1 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.

The Company is also committed under the terms of various leases to construct 
improvements for certain tenants totaling approximately $11.9 million.  Of 
this amount, approximately $5.3 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 to the 
property) at 1102/1124 Columbia Street and 3000/3018 Western Avenue.

S-11 (File No. 333-23545) initially filed with the Securities and Exchange 
Commission on March 18, 1997.

The following discussion should be read in conjunction with the financial
statements and notes appearing elsewhere in this report.

OVERVIEW

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

The Company's primary source of income is rental revenue (including tenant
recoveries) from its properties (the "Properties"). The Company has acquired
its current portfolio since the beginning of 1994, with four of the Properties
acquired in calendar year 1994, eight acquired in 1996, three acquired in 1997
in connection with the Offering, seven acquired in 1997 after the Offering
(together, the "1997 Acquired Properties") and 19 acquired in 1998 (the "1998
Acquired Properties"). As a result of the Company's acquisition activities in
1997 and 1998, the financial data shows significant increases in total revenue
and expenses for the 1998 periods compared to the 1997 periods.

RESULTS OF OPERATIONS

COMPARISON OF THREE MONTHS ENDED JUNE 30, 1998 ("SECOND QUARTER 1998") TO THREE
MONTHS ENDED JUNE 30, 1997 ("SECOND QUARTER 1997")

Rental revenue increased by $6.2 million, or 109%, to $11.9 million for 
Second Quarter 1998 compared to $5.7 million for Second Quarter 1997. The 
increase resulted primarily from rental revenue from the 1997 Acquired 
Properties purchased after April 1, 1997 and from the 1998 Acquired 
Properties, which together added an additional $6.2 million of rental 
revenue.  Of this amount, $155,000 represents the receipt of a rental 
termination payment associated with a lease at one of the Properties. Rental 
revenue from the Properties acquired before April 1, 1997 (the "Second 
Quarter Same Properties") increased by $28,000, or 1%, generally due to 
increases in rental rates.  Results for the Second Quarter Same Properties 
for Second Quarter 1998 were impacted by the vacancy of approximately 68,000 
square feet at 1102/1124 Columbia Street beginning May 31, 1998.  The Company 
is currently negotiating with tenants for substantially all of this vacant 
space.  Rental revenue for the Second Quarter Same Properties (excluding 
1102/1124 Columbia Street) increased by $85,000, or 2%.

Tenant recoveries increased by $1.1 million, or 61%, to $2.9 million for 
Second Quarter 1998 compared to $1.8 million for Second Quarter 1997. The 
increase resulted primarily from the 1997 Acquired Properties purchased after 
April 1, 1997 and the 1998 Acquired Properties, which together added an 
additional $1.0 million of tenant recoveries. Tenant recoveries from the 
Second Quarter Same Properties increased by $107,000, or 6%, primarily due to 
an increase in rental operating expenses, improved identification and recovery 
of costs at certain properties, and adjustments to tenant recoveries relating 
to operating expenses for prior periods.  Tenant recoveries for the Second 
Quarter Same Properties (excluding 1102/1124 Columbia Street) increased by 
$287,000, or 24%.

Interest and other income increased by $96,000, or 45%, to $308,000 for 
Second Quarter 1998 compared to $212,000 for Second Quarter 1997, resulting 
primarily from interest income from the secured note receivable.

Rental operating expenses increased by $1.6 million, or 80%, to $3.6 million 
for Second Quarter 1998 compared to $2.0 million for Second Quarter 1997. The 
increase resulted primarily from the 1997 Acquired Properties purchased after 
April 1, 1997 and the 1998 Acquired Properties, which together added an 
additional $1.6 million of rental operating expenses. Operating expenses for 
the Second Quarter Same Properties increased by approximately $55,000, or 3%, 
primarily due to an increase in utility expenses (due to greater usage) that 
are passed through to the tenants. Rental operating expenses for the Second 
Quarter Same Properties (excluding 1102/1124 Columbia Street) increased by 
$37,000, or 3%.

General and administrative expenses increased by $289,000, or 49%, to $882,000
for Second Quarter 1998 compared to $593,000 for Second Quarter 1997, due to
the Company's larger scope of operations and increased costs incurred as a
result of being a public company in 1998.


                                      13
<PAGE>

Stock compensation expense of $3.8 million was recorded for Second Quarter 1997
for the non-recurring, non-cash expense related to the issuance of stock grants
and options to officers, directors and certain employees of the Company,
principally in connection with the Offering.

Interest expense increased by $1.4 million, or 67%, to $3.5 million for 
Second Quarter 1998 compared to $2.1 million for Second Quarter 1997.  The 
increase resulted primarily from the indebtedness incurred to acquire the 
1997 Acquired Properties purchased after April 1, 1997 and the 1998 Acquired 
Properties, offset by the decrease in interest expense due to the 
indebtedness related to the Second Quarter Same Properties paid off in June 
1997 with proceeds from the Offering.

Acquisition LLC financing costs of $6,973,000 were expensed in Second Quarter 
1997, representing the portion of the purchase price of ARE Acquisitions, LLC 
(the "Acquisition LLC") in excess of the cost incurred by it to acquire its 
three Life Science Facilities.

Write-off of unamortized loan costs in Second Quarter 1997 represents the write-
off of loan costs associated with $72,698,000 of secured notes repaid with
proceeds of the Offering.

Depreciation and amortization increased by $1.4 million, or 127%, to $2.5 
million for Second Quarter 1998 compared to $1.1 million for Second Quarter 
1997. The increase resulted primarily from depreciation associated with the 
1997 Acquired Properties purchased after April 1, 1997, and the addition of 
the 1998 Acquired Properties.

As a result of the foregoing, there was net income of $4.7 million for Second
Quarter 1998 compared to a net loss of $10.9 million for Second Quarter 1997.


COMPARISON OF SIX MONTHS ENDED JUNE 30, 1998 ("SIX MONTHS 1998") TO SIX MONTHS
ENDED JUNE 30, 1997 ("SIX MONTHS 1997")

Rental revenue increased by $10.1 million, or 93%, to $21.0 million for Six 
Months 1998 compared to $10.9 million for Six Months 1997. The increase 
resulted primarily from the 1997 Acquired Properties purchased after January 
1, 1997 and the 1998 Acquired Properties, which together added an additional 
$10.0 million of rental revenue. Of this amount, $277,000 represents the 
receipt of rental termination payments associated with leases at two of the 
Properties. Rental revenue from the Properties acquired before January 1, 
1997 (the "Same Properties") increased by $115,000, or 1%, generally due to 
increases in rental rates.  Results for the Same Properties for Six Months 
1998 were impacted by the vacancy of approximately 68,000 square feet at 
1102/1124 Columbia Street beginning May 31, 1998.  The Company is currently 
negotiating with tenants for substantially all of this vacant space.  Rental 
revenue for the Same Properties (excluding 1102/1124 Columbia Street) 
increased by $165,000, or 2%.

                                      14
<PAGE>

Tenant recoveries increased by $1.6 million, or 43%, to $5.3 million for Six 
Months 1998 compared to $3.7 for Six Months 1997. The increase resulted 
primarily from the 1997 Acquired Properties purchased after January 1, 1997 
and the 1998 Acquired Properties, which together added an additional $1.5 
million of tenant recoveries. Tenant recoveries for the Same Properties 
increased by $96,000, or 2.6%, generally due to an increase in rental 
operating expenses, improved identification and recovery of costs at certain 
properties, and adjustments to tenant recoveries relating to operating 
expenses for prior periods. Tenant recoveries for the Same Properties 
(excluding 1102/1124 Columbia Street) increased by $292,000, or 11%.

Interest and other income increased by $200,000, or 66%, to $501,000 for Six 
Months 1998 compared to $301,000 for Six Months 1997, resulting primarily 
from interest income from the secured note receivable.

Rental operating expenses increased by $2.3 million, or 61%, to $6.1 million 
for Six Months 1998 compared to $3.8 million for Six Months 1997. The 
increases resulted primarily from the 1997 Acquired Properties purchased 
after January 1, 1997 and the 1998 Acquired Properties, which together added 
an additional $2.2 million of rental operating expenses. Operating expenses 
for the Same Properties increased by $97,000, or 2.6%, primarily due to an 
increase in utility expenses (due to greater usage) that are passed through 
to the tenants. Rental operating expenses for the Same Properties (excluding 
1102/1124 Columbia Street) increased by $141,000, or 5%.

General and administrative expenses increased by $457,000, or 39%, to
$1.6 million for Six Months 1998 compared to $1.2 million for Six Months 1997
due to the Company's larger scope of operations and increased costs incurred as
a result of being a public company in 1998.

The special bonus of $353,000 in Six Months 1997 was awarded to an officer of
the Company in connection with the Offering and accrued for the period ended
March 31, 1997. Post-retirement benefit expense of $632,000 in Six Months 1997
reflects an adjustment for the non-cash accrual associated with a one-time post
retirement benefit for an officer of the Company. Stock compensation expense of
$4.2 million was recorded in Six Months 1997 for the non-recurring, non-cash
expense related to the issuance of stock grants and options to officers,
directors and certain employees of the Company, principally in connection with
the Offering.

Interest expense increased by $1.0 million, or 22%, to $5.6 million for Six 
Months 1998 compared to $4.6 million for Six Months 1997. The increase 
resulted primarily from indebtedness incurred to acquire the 1997 Acquired 
Properties purchased after January 1, 1997 and the 1998 Acquired Properties.

Acquisition LLC financing costs of $6,973,000 were expensed in Six Months 
1997, representing the portion of the purchase price of the Acquisition LLC 
in excess of the cost incurred by it to acquire its three Life Science 
Facilities.

Write-off of unamortized loan costs in Six Months 1997 represents the write-off
of loan costs associated with $72,698,000 of secured notes repaid with proceeds
of the Offering.


                                      15
<PAGE>

Depreciation and amortization increased by $2.1 million, or 100%, to $4.2 
million for Six Months 1998 compared to $2.1 million for Six Months 1997. The 
increase resulted primarily from depreciation associated with the 1997 
Acquired Properties purchased after January 1, 1997 and the 1998 Acquired 
Properties.

As a result of the foregoing, there was net income of $9.4 million for Six
Months 1998 compared to a net loss of $11.1 million for Six Months 1997.


LIQUIDITY AND CAPITAL RESOURCES

CASH FLOWS

Net cash provided by operating activities for Six Months 1998 increased by 
$11.2 million to $10.6 million compared to net cash used in operating 
activities of $662,000 for Six Months 1997. The increase resulted primarily 
from operating cash flows from the 1997 Acquired Properties purchased after 
January 1, 1997 and the 1998 Acquired Properties.

Net cash used in investing activities increased by $116.7 million to
$170.5 million for Six Months 1998 compared to net cash used in investing
activities of $53.8 million for Six Months 1997. The increase resulted
primarily from the costs associated with the acquisition of the 1998 Acquired
Properties.

Net cash provided by financing activities increased by $85.2 million to
$159.9 million for Six Months 1998 compared to net cash provided by financing
activities of $74.7 million for Six Months 1997. The increase resulted
primarily from $49.1 million in proceeds from secured debt, $87.2 million in
net borrowings under the unsecured line of credit and $33.2 million in net
proceeds from the issuance of common stock, partially offset by payments of
$9.1 million in dividends payable on common stock.

CAPITAL COMMITMENTS

The Company is committed to complete the construction of a building and 
certain improvements thereto in San Diego, California at a remaining cost of 
approximately $4.8 million under the terms of two leases.  In addition, the 
Company is committed to complete the construction of a building and certain 
improvements thereto in Gaithersburg, Maryland at a remaining cost of between 
$9.1 million and $18.1 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.

                                      16
<PAGE>

The Company is also committed under terms of various leases to construct 
improvements for tenants totaling approximately $11.9 million.  Of this 
amount, approximately $5.3 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 to the 
property) at 1102/1124 Columbia Street and 3000/3018 Western Avenue.

RESTRICTED CASH

As of June 30, 1998, the Company had $9.8 million in cash and cash 
equivalents, including $7.8 million in restricted cash accounts.  Of the $7.8 
million in restricted cash accounts, approximately $5.3 million has been set 
aside to complete the conversions described under "--Capital Commitments", 
approximately $1.7 million is held in trust as additional security required 
under the terms of the Company's secured notes payable, and approximately 
$850,000 is held in security deposit reserve accounts based on the terms of 
certain lease agreements.

UNSECURED LINE OF CREDIT

The Company has an unsecured line of credit providing for borrowings of up to
$150,000,000.  Borrowings under the line of credit bear interest at a floating
rate based on the Company's election of either a LIBOR based rate or the higher
of the bank's reference rate and the Federal Funds rate plus 0.5%.  For each
LIBOR based advance, the Company must elect to fix the rate for a period of
one, two, three or six months.


                                      17
<PAGE>

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 the Company
acquires additional unencumbered properties, borrowings available under the
line of credit will increase.  As of June 30, 1998, borrowings under the line
of credit were limited to approximately $150,000,000, and $110,200,000 was
outstanding (leaving $39,800,000 available) at a weighted average interest rate
of 7.16%.

The line of credit expires May 31, 2000 and provides for annual extensions
(provided there is no default) for one-year periods upon notice by the Company
and consent of the participating banks.

In August 1998, the Company amended its unsecured line of credit to provide 
for borrowings of up to $250 million.  As under the original line, borrowings 
under the line of credit, as amended, bear interest at a floating rate based 
on the Company's election of either a LIBOR based rate or the higher of the 
bank's reference rate and the Federal Funds rate plus 0.5%. However, under 
the line, as amended, the LIBOR based rate has been reduced, resulting in a 
rate of 6.91% as of August 5, 1998.  Financial covenants for the line of 
credit, as amended, are substantially similar to those under the original 
line.  The line, as amended, 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 bank.

LIQUIDITY AND CAPITAL RESOURCES

On May 29, 1998, the Company sold 1,150,000 shares of common stock to 
PaineWebber Incorporated for inclusion in the PaineWebber Equity Trust REIT 
Shares I, a unit investment trust.  The shares were issued at a price of 
$30.5625 per share (before discounts and commissions).  The aggregate 
proceeds to the Company, net of offering costs of $1.9 million, were 
approximately $33.2 million.

The Company expects to continue meeting its short-term liquidity and capital
requirements generally through its working capital and net cash provided by
operating activities.  The Company believes that the net cash provided by
operating activities will continue to be sufficient to pay any distributions
necessary to enable the Company to continue qualifying as a real estate
investment trust.  The Company also believes that net cash provided by
operations will be sufficient to fund its recurring non-revenue enhancing
capital expenditures, tenant improvements and leasing commissions.

The Company expects to meet certain long-term liquidity requirements, such as
property acquisitions, 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 unsecured line of credit, and the issuance of additional
debt and/or equity securities.

EXPOSURE TO ENVIRONMENTAL LIABILITIES

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

INFLATION

More than 70% of the Company's leases (on a square footage basis) are 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, a majority of the Company's leases (on a square footage
basis) contain effective annual rent escalations that are either fixed (ranging
from 2.5% to 4.0%) or indexed based on a CPI or other index. Accordingly, the
Company does not believe that its earnings or cash flow are subject to any
significant risk of inflation. An increase in inflation, however, could result
in an increase in the Company's variable rate borrowing cost, including
borrowings under the unsecured line of credit.

IMPACT OF 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 the
Company's 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, or engage in similar normal business activities.

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

FUNDS FROM OPERATIONS

Management believes that funds from operations (FFO) is helpful to investors as
a measure of the performance of an equity REIT because, along with cash flows
from operating activities, financing activities and investing activities, it
provides investors with


                                      19
<PAGE>

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

The following tables present the Company's FFO on a historical basis (in
thousands):

ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT
          MARKET RISK

Not applicable.


PART II - OTHER INFORMATION

ITEM 1.   LEGAL PROCEEDINGS

Since early 1998, the Company and its President, Alan D. Gold, have engaged 
in discussions regarding the potential termination of Mr. Gold's full-time 
employment and his entering into a consulting arrangement with the Company. 
While these discussions were ongoing, the Company gave Mr. Gold written 
notice that it did not wish to extend the term of his employment agreement 
past its December 31, 1998 expiration date. On July 16, 1998, Mr. Gold gave 
the Company written notice that he intended to terminate his employment 
agreement, allegedly for "good reason," on or before August 16, 1998. The 
Company disputes Mr. Gold's contention that he has "good reason" to terminate 
his employment agreement and has submitted the disputes between the parties 
to binding arbitration pursuant to the terms of Mr. Gold's employment 
agreement. Mr. Gold has asserted claims against the Company that also will be 
considered in the arbitration. The Company currently anticipates that Mr. 
Gold will leave as of August 16, 1998 and that other executives of the 
Company will assume Mr. Gold's responsibilities.

ITEM 2.   CHANGES IN SECURITIES AND USE OF PROCEEDS

On May 27, 1998, the Company privately placed 1,150,000 shares of its common 
stock, par value $.01 per share (the "Shares"), with PaineWebber Incorporated 
at a price before discounts and commissions of $30.5625 per Share, resulting 
in aggregate proceeds to the Company of approximately $33.2 million. Such 
proceeds were used to repay borrowings under the Company's unesecured line of 
credit. PaineWebber deposited the Shares with the trustee of PaineWebber 
Equity Trust REIT Series I (A Unit Investment Trust) (the "Trust"), a 
registered unit investment trust under the Investment Company Act of 1940, as 
amended, for which PaineWebber acted as sponsor and depositor, in exchange 
for units in the Trust. The issuance of the Shares was effected in reliance 
upon an exemption from registration under Section 4(2) of the Securities Act 
as a transaction by an issuer not involving a public offering. On June 9, 
1998, the Company filed a Registration Statement (File No. 333-56449) on Form 
S-3 with the Securities and Exchange Commission to register the Shares under 
the Securities Act of 1933, as amended.

ITEM 3.   DEFAULTS UPON SENIOR SECURITIES

None.

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

until their successors are duly elected and qualify. The directors elected 
were: Jerry M. Sudarsky, Joel S. Marcus, Alan D. Gold, Richard Jennings, 
Joseph Elmaleh, Viren Mehta, David M. Petrone and Anthony Solomon. There are 
no other directors of the Company. A total of 10,902,809 shares voted "for" 
each of the directors, 0 voted "against" and 16,180 shares abstained.


                                      21

In addition, the stockholders voted to ratify the selection of Ernst & Young 
LLP as the Company's independent public accountants for the fiscal year 
ending December 31, 1998. A total of 10,906,149 shares voted "for" the 
ratification, 7,300 voted "against" and 5,540 shares abstained.

The stockholders also voted to amend the Company's 1997 Stock Award and 
Incentive Plan (the "Plan") to increase the number of shares of common stock 
of the Company available for issuance thereunder from 900,000 shares to that 
number of shares equal to 10% of the number of shares of common stock 
outstanding at any time, PROVIDED, that in no event shall the number of 
shares available for issuance under the Plan exceed 3,000,000 shares of 
common stock. A total of 6,308,959 shares voted "for" the amendment, 
3,803,380 voted "against" and 17,982 shares abstained.

the 1st day of January, 1998 (the "Effective Date"), by and between 
ALEXANDRIA REAL ESTATE EQUITIES, INC., a Maryland corporation (the

(hereinafter, Corporation and Officer will be referred to collectively as the 
"Parties"), to read as follows:

                                       RECITAL

          WHEREAS, Corporation desires to employ Officer as its Chief 
Financial Officer, Treasurer and Secretary, and Officer is willing to accept 
such employment by Corporation, on the terms and subject to the conditions

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

1.        POSITION AND DUTIES; LOCATION.

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

Angeles, California metropolitan area, except for required travel on 
Corporation's business.

2.        TERM OF EMPLOYMENT.

          The term (the "Term") of this Agreement shall be for a period 
commencing on the Effective Date and ending on December 31, 1998 (the 
"Termination Date"), unless terminated earlier pursuant to this Agreement 
(the "Early Termination Date"); PROVIDED, HOWEVER, that commencing on 
December 31, 1998 and on each subsequent anniversary thereof, the Term shall 
be automatically extended for one (1) additional year unless, no later than 
ninety (90) days before such date, either party shall have given written 
notice to the other that it does not wish to extend the Term of this 
Agreement.  References herein to the Term shall refer to both the initial 
Term and any such extended Term.

3.        COMPENSATION, BENEFITS AND REIMBURSEMENT.

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

               (a)    MINIMUM BASE.  During the Term and subject to the terms 
and conditions set forth herein, Corporation agrees to pay to Officer an 
annual "Base Salary" of One Hundred Seventy Five Thousand Dollars ($175,000), 
or such other amount as may from time-to-time be determined by Corporation.  
Unless otherwise agreed in writing by Officer and Corporation, and subject to 
Subparagraph (b) below, the base salary shall be payable in substantially 
equal semimonthly installments in accordance with the standard policies of 
Corporation in existence from time-to-time.

               (b)    EARNED BASE SALARY.  For purposes of any early 
termination of this Agreement as provided in Paragraph 4 below, the term 
"Earned Base Salary" shall mean all semimonthly installments of the Base 
Salary which have become due and payable to Officer pursuant to this 
Paragraph 3.1, together with any partial monthly installment prorated on a 
daily basis up to and including the applicable Termination Date.

                                       2
<PAGE>

          3.2    ADJUSTMENTS IN BASE SALARY.  Officer's Base Salary shall be 
reviewed for the possibility of adjustments no less frequently than on each 
anniversary of the Effective Date during the Term by the Board (or such 
committee as may be appointed by the Board for such purpose); PROVIDED, 
HOWEVER, that the first such review shall take place as soon as practicable 
following the end of the Corporation's 1997 fiscal year.  The Base Salary 
payable to Officer may be increased on each such date (and such other times 
as the Board or a committee of the Board may deem appropriate during the 
Term) to an amount determined by the Chief Executive Officer with the 
concurrence of the Board (or a committee of the Board).  Each such new Base 
Salary shall become the base for each successive year increase.  Any increase 
in Base Salary or other compensation shall in no way limit or reduce any 
other obligations of Corporation hereunder and, once established at an 
increased specified rate, Officer's Base Salary shall not be reduced unless 
Officer otherwise agrees in writing.

          3.3    DISCRETIONARY BONUS.  During the Term if Officer is in good 
standing as finally determined by the Chief Executive Officer with the 
concurrence of the Board (or a committee of the Board), the Officer may be 
eligible for a performance bonus.  Officer may be eligible to receive a 
discretionary bonus for each fiscal year of Corporation (or portion thereof) 
during the Term, with the actual amount of any such bonus to be determined by 
the Chief Executive Officer with the concurrence of the Board (or a committee 
of the Board) based upon an evaluation of the Corporation's and Officer's 
performance during such year and such other factors and conditions as the 
Chief Executive Officer with the concurrence of the Board (or a committee of 
the Board) deems relevant.  Any such bonus shall be payable within one 
hundred and twenty (120) days after the end of Corporation's fiscal year to 
which such bonus relates. 

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

               (a)    OFFICER BENEFITS.  During the Term, Officer shall be
eligible to participate in such Corporation's benefit and deferred compensation
plans as are made available to executive officers of Corporation in accordance
with the terms and conditions of such plans,  including, without limitation,
Corporation's stock incentive plans, annual incentive

                                       3

compensation plans, profit sharing/pension plans, deferred compensation 
plans, annual physical examinations, dental, vision, sick pay, disability, 
and medical plans, personal catastrophe and accidental death insurance plans, 
financial planning and automobile arrangements, retirement plans and 
supplementary executive retirement plans, if any. During the Term, 
Corporation shall pay one hundred percent (100%) of Officer's medical 
premiums under Corporation's medical plan and any other welfare benefit plans 
for which Officer qualifies that are in existence from time-to-time.

               (b)    VACATION.  During the Term, Officer shall be entitled 
to up to three (3) weeks of paid vacation annualized during each calendar 
year during the Term and any extensions thereof, prorated for partial years.  
Accrued vacation not taken during any calendar year may be carried forward to 
subsequent years; PROVIDED, THAT Officer may not accrue more than six (6) 
weeks of unused vacation at any time.

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

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

               (d)    REIMBURSEMENT FOR EXPENSES.  During the Term, 
Corporation shall reimburse Officer for all reasonable out-of-pocket business 
and/or entertainment expenses incurred by Officer for the purpose of and in 
connection with the performance of his services pursuant to this Agreement.  
Officer shall be entitled to such reimbursement upon the presentation by 
Officer to Corporation of vouchers or other statements itemizing such 
expenses in reasonable detail consistent with Corporation's 

                                        4

then existing policies.  In addition, Officer shall be entitled to 
reimbursement for (i) dues and membership fees in professional organizations 
and/or industry associations in which Officer is currently a member or 
becomes a member, and (ii) appropriate industry seminars and mandatory 
continuing education.

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

4.        TERMINATION OF THIS AGREEMENT.

          4.1    TERMINATION BY CORPORATION DEFINED.

               (a)    TERMINATION WITHOUT CAUSE.  Subject to the provisions

<PAGE>

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

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

defined in Paragraph 4.2(b) below), at any time prior to the Termination 
Date, upon written notice delivered to Corporation thirty (30) days prior to 
the effective date of termination specified in such notice (which date shall 
be the applicable Early Termination Date).

               (b)    TERMINATION FOR GOOD REASON.  Subject to the provisions 
of Paragraph 4.3 below, Officer shall have the right to terminate this 
Agreement prior to the Termination Date in the event of the material breach 
of this Agreement by Corporation, if such breach is not cured by Corporation 
within thirty (30) days after written notice thereof specifying the nature of 
such breach has been delivered to Corporation, or, following a Change in 
Control (as defined in Paragraph 4.4(d) below), under the

                                        6

Agreement, termination of this Agreement by Officer in the event of 
Corporation's material breach of this Agreement in accordance with the

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

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

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

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

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

                                        7


<PAGE>

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

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

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

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

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

               (c)    FULL SETTLEMENT OF ALL OBLIGATIONS.  Officer hereby

solicitation, relating to the election of directors of the Corporation) whose 
appointment or election by the Board or nomination for election by the 
Corporation's stockholders was approved or recommended by a vote of at least 
two-thirds (2/3) of the directors then still in office who either were 
directors on the date hereof or whose appointment, election or nomination for 
election was previously so approved or recommended; or 

                    (iii)  There is consummated a merger or consolidation of 
the Corporation with any other corporation, other than (A) a merger or 
consolidation which would result in the voting securities of the Corporation

securities of the surviving entity or any parent thereof), in combination 
with the ownership of any trustee or other fiduciary holding securities under 
an employee benefit plan of the Corporation or any subsidiary of the 
Corporation, at least seventy-five percent (75%) of the combined voting power 
of the securities of the Corporation or such surviving entity or any parent 
thereof outstanding immediately after such merger or consolidation, or (B) a

stockholders of the Corporation in substantially the same proportions as

          4.5    GROSS-UP.  If any of the Total Payments (as hereinafter 
defined) will be subject to the tax (the "Excise Tax") imposed by Section 
4999 of the Internal Revenue Code of 1986, as amended (the "Code") (the 
"Excise Tax"), Corporation shall pay to Officer, no later than the tenth 
(10th) day following the Early Termination Date, an additional amount (the 
"Gross-Up Payment") such that the net amount retained by him, after deduction 
of any Excise Tax on the Total Payments and any federal, state and local 
income tax and excise tax upon the payment provided for by this Paragraph, 
shall be equal to the Total Payments.  For purposes of determining whether 
any of the Total Payments will be subject to the Excise Tax and the amount of 
such Excise Tax, (i) all payments or benefits received or to be received by 
Officer in connection with a Change in Control or the termination of 
Officer's employment (whether payable pursuant to the terms of this Agreement 
or of any other plan, arrangement or agreement with Corporation, its 
successors, any person whose actions result in a Change in Control or any 
person affiliated (or which, as a result of the completion of the 
transactions causing a Change in Control, will become affiliated) with 
Corporation or such person within the meaning of Section 1504 of the Code 
(the "Total Payments")) shall be treated as "parachute payments" (within the 
meaning of Section 280G(b)(2) of the Code) unless, in the opinion of tax 
counsel selected by Corporation's independent auditors and reasonably 
acceptable to Officer, such payments or benefits (in whole or in part) do not 
constitute parachute payments, including by reason of Section 280G(b)(4)(A) 
of the Code, and all "excess parachute payments" (within the meaning of 
Section 280G(b)(1) of the Code) shall be treated as subject to the Excise 
Tax, unless in the opinion of such tax counsel such excess parachute payments 
represent reasonable compensation for services actually rendered within the 
meaning of Section 280G(b)(4)(B) of the Code, or are not otherwise subject to 
the Excise Tax,

                                        13

<PAGE>

and (ii) the value of any noncash benefits or any deferred payment or benefit 
shall be determined by the Corporation's independent auditors in accordance 
with the principles of Sections 280G(d)(3) and (4) of the Code. For purposes 
of determining the amount of the Gross-Up Payment, Officer shall be deemed to 
pay federal income taxes at the highest marginal rate of federal income 
taxation in the calendar year in which the Gross-Up Payment is to be made and 
state and local income taxes at the highest marginal rate of taxation in the 
state and locality of the residence of Officer on the Early Termination Date, 
net of the maximum reduction in federal income taxes that could be obtained 
from deduction of such state and local taxes.

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

5.        NONCOMPETITION/NONSOLICITATION.

          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 (i) engage in any activity competitive with the business of 
Corporation or (ii) solicit any employee of the Corporation (or its 
affiliates) to work for any business, individual, partnership, firm, 
corporation or other entity then in competition with the business of the 
Corporation (or any of its affiliates).

6.        MISCELLANEOUS.

          6.1    PAYMENT OBLIGATIONS.  Corporation's obligation to pay 
Officer the compensation and to make the arrangements provided herein shall 
be unconditional, and Officer shall have no obligation whatsoever to mitigate 
damages hereunder.  If arbitration after a Change in Control shall be brought 
to enforce or interpret any provision contained herein, Corporation shall, to 
the extent permitted by applicable law and Corporation's 

                                        14

Charter and By-Laws, indemnify Officer for Officer's reasonable attorneys' 
fees and disbursements incurred in such arbitration.

          6.2    CONFIDENTIALITY.  Without limiting the scope of the 
Agreement Regarding Proprietary Information between the Parties, dated as of 
December 30, 1997 (the "Proprietary Information Agreement"), Officer agrees 
that all confidential and proprietary information relating to the business of 
Corporation shall be kept and treated as confidential both during and after 
the Term, except as may be permitted in writing by the Board or as such 
information is within the public domain or comes within the public domain 
without any breach of this Agreement.

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

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

          6.5    NOTICES.  All notices and other communications under this 
Agreement shall be in writing and shall be given by facsimile or first-class

the exclusive remedy of the Parties hereto.  The resulting arbitration shall

competent jurisdiction.  Submission to arbitration shall not preclude the 
right of any party hereto involved in a dispute regarding this Agreement

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 arbitra-

tion; PROVIDED, HOWEVER, that any dispute following a Change in 
Control shall be governed by the provisions of Paragraph 6.1 above.  The 
arbitrator shall make such determination and apportionment whether or not the 
dispute proceeds to a final award.

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

shall be deemed valid and enforceable to the lawfully permitted.

obligations hereunder shall not be terminated by reason of any liquidation,

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

shall be binding upon and inure to the benefit of the surviving or resulting 
corporation or person.  This Agreement shall be binding upon and inure to the 
benefit of the executors, administrators, heirs, successors and assigns of 
the Parties; PROVIDED, HOWEVER, that except as herein expressly provided,

benefits or otherwise) or by Officer.

practicable but in any event by the date (the "FILING DEADLINE DATE") 30 days 
after the date hereof, a registration statement for an offering to be made on 
a delayed or continuous basis pursuant to Rule 415 of the Securities Act, as 
such Rule may be amended from time to time, or any similar rule or regulation 
hereafter adopted by the SEC, registering the resale from time to time by 
Holders thereof of all of the Registrable Securities (the "INITIAL SHELF 
REGISTRATION STATEMENT").  The Initial Shelf Registration Statement shall be 
on Form S-3 or another appropriate form permitting registration of such 
Registrable Securities for resale by such Holders in accordance with the 
methods of distribution elected by the Holders and set forth in the Initial 
Shelf Registration Statement.  The Company shall use its best efforts to 
cause the Initial Shelf Registration Statement to become effective under the 
Securities Act as promptly as is practicable but in any event by the date 
(the "EFFECTIVENESS DEADLINE DATE") 90 days after the date hereof, and to 
keep the Initial Shelf Registration Statement continuously effective under 
the Securities Act until the expiration of the Effectiveness Period.  At the 
time the Initial Shelf Registration Statement becomes effective, each Holder 
shall be named as a selling securityholder in the Initial Shelf Registration 
Statement and the related Prospectus in such a manner as to permit such 
Holder to deliver such Prospectus to purchasers of Registrable Securities in 
accordance with applicable law; PROVIDED, HOWEVER, that the Company shall not 
be obligated to include such Holder as a selling securityholder if the 
Company shall have reasonably requested additional information from such 
Holder and the Holder shall have failed to provide such information at least 
ten days prior to such time of effectiveness.

          (b)  If a Shelf Registration Statement ceases to be effective for 
any reason at any time during the Effectiveness Period, the Company shall use 
its best efforts to obtain the prompt withdrawal of any order suspending the 
effectiveness thereof, and in any event shall within 15 days of such 
cessation of effectiveness amend the Shelf Registration Statement in a manner 
reasonably expected to obtain the withdrawal of the order suspending the 
effectiveness thereof, or file an additional Shelf Registration Statement 
covering all of the securities that as of the date of such filing are 
Registrable Securities (a "SUBSEQUENT SHELF REGISTRATION STATEMENT").  If a 
Subsequent Shelf Registration Statement is filed, the Company shall use its 
best efforts to cause the Subsequent Shelf Registration Statement to become 
effective as promptly as is practicable after such filing and to keep the 
Subsequent Registration Statement continuously effective until the end of the 
Effectiveness Period.

                                        5

          (c)  The Company shall supplement and amend the Shelf Registration 
Statement if reasonably requested by the holders of a majority of shares 
constituting Registrable Securities unless it is determined, in writing, by 
counsel for the Company not to be required by the Securities Act taking into 
consideration all relevant facts and circumstances, including, without 
limitation, the Holders' anticipated methods of distribution of the 
Registrable Securities.

          (d)  Each Holder wishing to sell Registrable Securities pursuant to 
a Shelf Registration Statement and related Prospectus agrees to deliver a 
duly completed Notice and Questionnaire to the Company at least ten Business 
Days prior to the initial intended distribution of Registrable Securities by 
such Holder under the Shelf Registration Statement.  From and after the date 
the Initial Shelf Registration Statement becomes effective, the Company 
shall, as promptly as is practicable after the date a Notice and 
Questionnaire is delivered, and in any event within seven Business Days after 
receipt of a completed Notice and Questionnaire:

               (i)  if required by applicable law, file with the SEC a 
post-effective amendment to the Shelf Registration Statement or prepare and, 
if required by applicable law, file a supplement to the related Prospectus or 
a supplement or amendment to any document incorporated therein by reference 
or file any other required document so that the Holder delivering such Notice 
and Questionnaire is named as a selling securityholder in the Shelf 
Registration Statement and the related Prospectus in such a manner as to 
permit such Holder to deliver such Prospectus to purchasers of the 
Registrable Securities in accordance with applicable law; PROVIDED, HOWEVER, 
that the Company shall not be obligated to include such Notice Holder as a 
selling securityholder if the Company shall have reasonably requested 
additional information from such Notice Holder until the Notice Holder shall 
have provided such requested information; and, if the Company shall file a 
post-effective amendment to the Shelf Registration Statement, the Company 
shall use its best efforts to cause such post-effective amendment to become 
effective under the Securities Act as promptly as is practicable, but in any 
event by the date (the "AMENDMENT EFFECTIVENESS DEADLINE DATE") 45 days after 
the date such post-effective amendment is required by this clause to be filed;

               (ii)      provide such Holder a copy of any documents filed 
pursuant to Section 3(d)(i) hereof; and 

               (iii)     notify such Holder as promptly as practicable after 
the effectiveness under the Securities Act of any post-effective amendment 
filed pursuant to Section 3(d)(i) hereof; PROVIDED, HOWEVER, that if such 
Notice and Questionnaire is delivered during a Deferral Period, the Company 
shall so inform the Holder delivering such Notice and Questionnaire and shall 
take the actions set forth in clauses (i), (ii) and (iii) above, to the 
extent necessary, upon expiration of the Deferral Period in accordance with 
Section 4(i).  The Company shall be under no obligation to name any Holder 
that is not a Notice Holder as a selling securityholder in any Shelf 
Registration Statement or related Prospectus.

                                        6

     SECTION 4.   REGISTRATION PROCEDURES.  In connection with the 
registration obligations of the Company under Section 3 hereof, the Company 
shall:

          (a)  Before filing any Registration Statement or Prospectus or any 
amendments or supplements thereto with the SEC, furnish to the Initial 
Purchaser three copies of all such documents proposed to be filed.

          (b)  Prepare and file with the SEC such amendments and 
post-effective amendments to each Registration Statement as may be necessary 
to keep such Registration Statement continuously effective from the 
Effectiveness Deadline Date to the expiration of the Effectiveness Period; 
cause the related Prospectus to be supplemented by any required prospectus 
supplement, and as so supplemented to be filed pursuant to Rule 424 (or any 
similar provisions then in force) under the Securities Act; and use its best 
efforts to comply with the provisions of the Securities Act applicable to it 
with respect to the disposition of all securities covered by such 
Registration Statement until the expiration of the Effectiveness Period in 
accordance with the intended methods of disposition by the sellers thereof 
set forth in such Registration Statement as so amended or such Prospectus as 
so supplemented.

          (c)  As promptly as practicable, give notice to the Holders and the 
Initial Purchaser (i) when any Prospectus, prospectus supplement, 
Registration Statement or post-effective amendment to a Registration 
Statement has been filed with the SEC and, with respect to a Registration 
Statement or any post-effective amendment, when the same has become 
effective, (ii) of any request, following the effectiveness of the Initial 
Shelf Registration Statement under the Securities Act, by the SEC or any 
other federal or state governmental authority for amendments or supplements 
to any Registration Statement or related Prospectus or for additional 
information, (iii) of the issuance by the SEC or any other federal or state 
governmental authority of any stop order suspending the effectiveness of any 
Registration Statement or the initiation or threatening of any proceedings 
for that purpose, (iv) of the receipt by the Company of any notification with 
respect to the suspension of the qualification or exemption from 
qualification of any of the Registrable Securities for sale in any 
jurisdiction or the initiation or threatening of any proceeding for such 
purpose, (v) of the occurrence of a Material Event and (vi) of the 
determination by the Company that a post-effective amendment to a 
Registration Statement would be appropriate, which notice may, at the 
discretion of the Company (or as required pursuant to Section 4(i)), state 
that it constitutes a Deferral Notice, in which event the provisions of 
Section 4(i) shall apply.

          (d)  Use its best efforts to obtain the withdrawal of any order 
suspending the effectiveness of a Registration Statement or the lifting of 
any suspension of the qualification (or exemption from qualification) of any 
of the Registrable Securities for sale in any jurisdiction in which they have 
been qualified for sale, in either case as promptly as reasonably practicable.

          (e)  If reasonably requested by the Initial Purchaser or any Notice 
Holder, as promptly as practicable incorporate in a prospectus supplement or 
post-effective amendment to a Registration Statement such information as the 
Initial Purchaser or such Notice Holder shall,

                                        7

<PAGE>

based on the advice of counsel, determine to be required to be included 
therein by applicable law and make any required filings of such prospectus 
supplement or such post-effective amendment; PROVIDED, HOWEVER, that the 
Company shall not be required to take any actions under this Section 4(e) 
that are not, based on the written advice of counsel for the Company, in 
compliance with applicable law or during a Deferral Period.

          (f)  As promptly as practicable furnish to each Notice Holder and 
the Initial Purchaser, without charge, at least one conformed copy of any 
Registration Statement and any amendment thereto, including exhibits, and all 
documents incorporated or deemed to be incorporated therein by reference.

          (g)  Deliver to each Notice Holder in connection with any sale of 
Registrable Securities pursuant to a Registration Statement, without charge, 
as many copies of the Prospectus relating to such Registrable Securities 
(including each preliminary prospectus) and any amendment or supplement 
thereto as such Notice Holder may reasonably request; and the Company hereby 
consents to the use of the Prospectus and each amendment or supplement 
thereto by each Notice Holder in connection with any offering and sale of the 
Registrable Securities covered by such Prospectus or any amendment or 
supplement thereto in the manner set forth therein.

          (h)  Prior to any public offering of the Registrable Securities, 
register or qualify or cooperate with the Notice Holders in connection with 
the registration or qualification (or exemption from such registration or 
qualification) of such Registrable Securities for offer and sale under the 
securities or Blue Sky laws of such jurisdictions within the United States as 
any Notice Holder reasonably requests in writing (which request shall be 
included in the Notice and Questionnaire); keep each such registration or 
qualification (or exemption therefrom) effective during the Effectiveness 
Period and do any and all other acts or things necessary or advisable to 
enable the disposition in such jurisdictions of such Registrable Securities 
in the manner set forth in the applicable Registration Statement and the 
related Prospectus; PROVIDED, HOWEVER, that the Company shall not be required 
to register or qualify as a foreign corporation where it is not now so 
qualified or to take any action that would subject it to the service of 
process in suits or to taxation, other than as to matters and transactions 
relating to the Registration Statement and the related Prospectus, in any 
jurisdiction where it is not now so subject.

          (i)  Upon (A) the issuance by the SEC of a stop order suspending 
the effectiveness of the Shelf Registration Statement or the initiation of 
proceedings with respect to the Shelf Registration Statement under Section 
8(d) or 8(e) of the Securities Act, (B) the occurrence of any event or the 
existence of any fact (a "MATERIAL EVENT") as a result of which any 
Registration Statement shall contain any untrue statement of a material fact 
or omit to state any material fact required to be stated therein or necessary 
to make the statements therein not misleading, or any Prospectus shall 
contain any untrue statement of a material fact or omit to state any material 
fact required to be stated therein or necessary to make the statements 
therein, in the light of the circumstances under which they were made, not 
misleading, or (C) the occurrence or existence of any pending corporate 
development or public filing with the 

                                        8

<PAGE>

SEC that, in the discretion of the Company, makes it appropriate to suspend 
the availability of the Shelf Registration Statement and the related 
Prospectus, the Company shall:

               (i)  in the case of clause (B) above, subject to the next 
sentence, as promptly as practicable prepare and file, if necessary pursuant 
to applicable law, a post-effective amendment to such Registration Statement 
or a supplement to the related Prospectus or any document incorporated 
therein by reference or file any other required document that would be 
incorporated by reference into such Registration Statement and Prospectus so 
that such Registration Statement does not contain any untrue statement of a 
material fact or omit to state any material fact required to be stated 
therein or necessary to make the statements therein not misleading, and such 
Prospectus does not contain any untrue statement of a material fact or omit 
to state any material fact required to be stated therein or necessary to make 
the statements therein, in the light of the circumstances under which they 
were made, not misleading, as thereafter delivered to the purchasers of the 
Registrable Securities being sold thereunder, and, in the case of a 
post-effective amendment to a Registration Statement, subject to the next 
sentence, use its best efforts to cause such Registration Statement to become 
effective as promptly as is practicable, and 

               (ii)      give notice to the Notice Holders that the 
availability of the Shelf Registration Statement is suspended (a "DEFERRAL 
NOTICE") and, upon receipt of any Deferral Notice, each Notice Holder shall 
not sell any Registrable Securities pursuant to the Registration Statement 
until such Notice Holder's receipt of copies of the supplemented or amended 
Prospectus provided for in clause (i) above, or until it (x) is advised in 
writing by counsel for the Company that the Prospectus may be used and (y) 
has received copies of any additional or supplemental filings that are 
incorporated or deemed incorporated by reference in such Prospectus.

The Company will use its best efforts to ensure that the use of the 
Prospectus may be resumed (x) in the case of clause (A) above, as promptly as 
is practicable, (y) in the case of clause (B) above, as soon as, in the sole 
judgment of the Company, public disclosure of such Material Event would not 
be prejudicial to or contrary to the interests of the Company or, if 
necessary to avoid unreasonable burden or expense, as soon as practicable 
thereafter and (z) in the case of clause (C) above, as soon as, in the 
discretion of the Company, such suspension is no longer appropriate.  
Notwithstanding the foregoing, the Company may not (i) impose in excess of 
two Deferral Periods (which together shall not exceed 60 days) during any 
12-month period or (ii) at any time, impose a Deferral Period if a Deferral 
Period has been in effect within the preceding seven days.

          (j)  Enter into such customary agreements and take all such other 
customary actions in connection therewith (including those requested by the 
Holders of a majority of the Shares constituting Registrable Securities being 
sold) in order to expedite or facilitate the disposition of such Registrable 
Securities including, but not limited to, an underwritten offering and in 
connection therewith:

                                        9

<PAGE>

               (i)  provide customary indemnities to underwriters in 
connection with underwritten offerings and to the extent possible, make such 
representations and warranties to the Holders and any underwriters of such 
Registrable Securities with respect to the business of the Company and its 
subsidiaries, the Registration Statement, Prospectus and documents 
incorporated by reference therein, if any, in each case, in form, substance 
and scope as are customarily made by issuers to underwriters in underwritten 
offerings and confirm the same if and when requested;

               (ii)      obtain opinions of counsel to the Company and 
updates thereof (which counsel and opinions, in form, scope and substance, 
shall be reasonably satisfactory to the Holders of a majority of the Shares 
constituting Registrable Securities being sold, such underwriters and their 
respective counsel) addressed to each selling Holder and underwriter of 
Registrable Securities, covering the matters customarily covered in opinions 
requested in underwritten offerings;

               (iii)     obtain "cold comfort" letters and updates thereof 
from the independent certified public accountants of the Company (and, if 
necessary, any other certified public accountant of any subsidiary of the 
Company, or of any business acquired or to be acquired by the Company for 
which financial statements and financial data are or are required to be 
included in the Registration Statement) addressed to each selling Holder and 
underwriter of Registrable Securities, such letters to be in customary form 
and covering matters of the type customarily covered in "cold comfort" 
letters in connection with underwritten offerings; and 

               (iv)      deliver such documents and certificates as may be 
reasonably requested by the Holders of a majority of the Shares constituting 
Registrable Securities being sold, the underwriters and their respective 
counsel to evidence the continued validity of the representations and 
warranties of the Company made pursuant to clause (i) above and to evidence 
compliance with any customary conditions contained in the underwriting 
agreement or other agreement entered into by the Company.  

The above shall be done at each closing under such underwriting or similar 
agreement as and to the extent required thereunder.

          (k)  If requested in connection with a disposition of Registrable 
Securities pursuant to a Registration Statement, make reasonably available 
for inspection by the Notice Holders of such Registrable Securities and any 
broker-dealers, attorneys and accountants retained by such Notice Holders, 
all relevant financial and other records, pertinent corporate documents and 
properties of the Company and its subsidiaries that are not otherwise 
publicly available, and cause the executive officers, directors and 
designated employees of the Company and its subsidiaries to make reasonably 
available for inspection all relevant information reasonably requested by 
such Notice Holders or any such broker-dealers, attorneys or accountants that 
is not otherwise publicly available in connection with such disposition, in 
each case as is customary for similar "due diligence" examinations; PROVIDED, 
HOWEVER, that any information that is designated by the Company, in good 
faith, as confidential at the time of delivery of such information shall be 
kept confidential by such 

                                        10

<PAGE>

Notice Holders or any such broker-dealer, attorney or accountant, unless such 
disclosure is made in connection with a court proceeding or is required by 
law, or such information becomes available to the public generally or through 
a third party without an accompanying obligation of confidentiality.

          (l)  Comply with all applicable rules and regulations of the SEC 
and make generally available to its securityholders earning statements (which 
need not be audited) satisfying the provisions of Section 11(a) of the 
Securities Act and Rule 158 thereunder (or any similar rule promulgated under 
the Securities Act) no later than 45 days after the end of any 12-month 
period (or 90 days after the end of any 12-month period if such period is a 
fiscal year) commencing on the first day of the first fiscal quarter of the 
Company commencing after the effective date of a Registration Statement, 
which statements shall cover said 12-month period.

          (m)  Cooperate with each Notice Holder to facilitate the timely 
preparation and delivery of certificates representing Registrable Securities 
to be sold pursuant to a Registration Statement, which certificates shall not 
bear any restrictive legends, and cause such Registrable Securities to be in 
such denominations and registered in such names as such Notice Holder may 
request.

          (n)  Provide a CUSIP number for all Registrable Securities not 
later than the effective date of the Initial Shelf Registration Statement and 
provide the Transfer Agent and Registrar with printed certificates for the 
Registrable Securities that are in a form eligible for deposit with the 
Depository Trust Company.

          (o)  Provide such information as is required for any filings 
required to be made with NASD Regulation, Inc.

     SECTION 5.   HOLDER'S OBLIGATIONS.  Each Holder agrees, by acquisition 
of the Registrable Securities, that no Holder of Registrable Securities shall 
be entitled to sell any of such Registrable Securities pursuant to a 
Registration Statement or to receive a Prospectus relating thereto, or to 
receive the benefits of Section 2 or 3 hereof, unless such Holder has 
furnished the Company with a Notice and Questionnaire as required pursuant to 
Section 3(d) hereof (including the information required to be included in 
such Notice and Questionnaire) and the information set forth in the next 
sentence.  Each Notice Holder shall promptly furnish to the Company all 
information required to be disclosed in order to make the information 
previously furnished to the Company by such Notice Holder not misleading and 
any other information regarding such Notice Holder and the distribution of 
such Registrable Securities as the Company may from time to time reasonably 
request.  Any sale of any Registrable Securities by any Holder pursuant to a 
Registration Statement shall constitute a representation and warranty by such 
Holder that the information relating to such Holder and its plan of 
distribution is as set forth in the Prospectus delivered by such Holder in 
connection with such disposition, that such Prospectus does not as of the 
time of such sale contain any untrue statement of a material fact relating to 
or provided by such Holder or relating to its plan of distribution and that 
such Prospectus does not as of the time of such sale omit to state any 

                                        11

<PAGE>

material fact relating to or provided by such Holder or relating to its plan 
of distribution necessary to make the statements in such Prospectus, in the 
light of the circumstances under which they were made, not misleading.

     SECTION 6.   EXPENSES.  The Company shall bear all fees and expenses 
incurred in connection with the performance by the Company of its obligations 
under Sections 2, 3 and 4 hereof whether or not any Registration Statement 
becomes effective. Such fees and expenses shall include, without limitation, 
(i) all registration and filing fees (including, without limitation, fees and 
expenses (x) with respect to filings required to be made with NASD 
Regulation, Inc. and (y) to comply with federal and state securities or Blue 
Sky laws), (ii) reasonable printing expenses (including, without limitation, 
expenses of printing certificates for Registrable Securities in a form 
eligible for deposit with The Depository Trust Company), (iii) reasonable 
duplication expenses relating to copies of any Registration Statement or 
Prospectus delivered to any Holders hereunder, (iv) fees and disbursements of 
counsel for the Company in connection with any Shelf Registration Statement 
and any opinion reasonably requested of such counsel by the Transfer Agent 
and Registrar and (v) reasonable fees and disbursements of the Transfer Agent 
and Registrar.  In addition, the Company shall pay the internal expenses of 
the Company (including, without limitation, all salaries and expenses of 
officers and employees performing legal or accounting duties), the expense of 
any annual audit, the fees and expenses incurred in connection with the 
listing of the Registrable Securities on any securities exchange on which 
similar securities of the Company are then listed and the fees and expenses 
of any person, including special experts, retained by the Company.  
Notwithstanding the provisions of this Section 6, each seller of Registrable 
Securities shall pay all registration expenses to the extent the Company is 
prohibited by applicable Blue Sky laws from paying such expenses for or on 
behalf of such seller of Registrable Securities.  In addition, the Company 
shall bear the fees and expenses described in Section 2(d) hereof.

     SECTION 7.   INDEMNIFICATION.

          (a)  The Company will indemnify and hold harmless the Initial 
Purchaser and each Holder, the directors, officers, employees and agents of 
the Initial Purchaser and each Holder, and each person, if any, who controls 
the Initial Purchaser and each Holder within the meaning of Section 15 of the 
Securities Act or Section 20 of the Exchange Act, from and against any and 
all losses, claims, liabilities, expenses and damages (including, but not 
limited to, any and all investigative, legal and other expenses reasonably 
incurred (in accordance with subsection (c) below) in connection with, and 
any and all amounts paid in settlement of, any action, suit or proceeding 
between any of the indemnified parties and any indemnifying parties or 
between any indemnified party and any third party, or otherwise, or any claim 
asserted), as and when incurred, to which any such person, may become subject 
under the Securities Act, the Exchange Act or other Federal or state 
statutory law or regulation, at common law or otherwise, insofar as such 
losses, claims, liabilities, expenses or damages arise out of or are based on 
(i) any untrue statement or alleged untrue statement of a material fact 
contained in any Registration Statement or any amendment or supplement 
thereto, or in any application or other document executed by the Company 
filed in any jurisdiction in order to qualify the

                                        12

<PAGE>

Shares under the securities laws thereof or filed with the SEC, (ii) the 
omission or alleged omission to state in such document a material fact 
required to be stated in it or necessary to make the statements in it not 
misleading or (iii) any act or failure to act or any alleged act or failure 
to act by the Initial Purchaser or such Holder in connection with, or 
relating in any manner to, the Shares or the private placement contemplated 
hereby, and which is included as part of or referred to in any loss, claim, 
liability, expense or damage arising out of or based upon matters covered by 
clause (i) or (ii) above (provided that the Company shall not be liable under 
this clause (iii) to the extent it is finally judicially determined by a 
court of competent jurisdiction that such loss, claim, liability, expense or 
damage resulted directly from any such acts or failures to act undertaken or 
omitted to be taken by the Initial Purchaser or such Holder through its gross 
negligence or willful misconduct); provided that the Company will not be 
liable to the extent that such loss, claim, liability, expense or damage 
arises from the sale of the Shares in the offering to any person by the 
Initial Purchaser or such Holder and results solely from an untrue statement 
of a material fact contained in, or the omission of a material fact from, 
such Registration Statement, which untrue statement or omission was 
completely corrected in the Registration Statement (as then amended or 
supplemented) if the Company shall sustain the burden of proving the Initial 
Purchaser or such Holder sold Shares to the person alleging such loss, claim, 
liability, expense or damage without sending or giving, at or prior to the 
written confirmation of such sale, a copy of the Registration Statement (as 
then amended or supplemented) if the Company had previously furnished copies 
thereof to the Initial Purchaser or such Holder within a reasonable amount of 
time (which in any event shall be no less than 24 hours) prior to the sale of 
the Shares to the person asserting such loss, claim, liability, expense or 
damage, and the Initial Purchaser or such Holder failed to deliver the 
corrected Registration Statement, if required by law to have so delivered it 
and if delivered would have been a complete defense against the person 
asserting such loss, claim, liability, expense or damage.  This indemnity 
agreement will be in addition to any liability that the Company might 
otherwise have.

          (b)  The Initial Purchaser and each Holder severally agrees to 
indemnify and hold harmless the Company, each person, if any, who controls 
the Company within the meaning of Section 15 of the Securities Act or Section 
20 of the Exchange Act and each director of the Company to the same extent as 
the foregoing indemnity from the Company to the Initial Purchaser and such 
Holder, but only insofar as losses, claims, liabilities, expenses and damages 
arise out of or are based on any untrue statement or omission or alleged 
untrue statement or omission made in reliance on and in conformity with 
information relating to the Initial Purchaser or such Holder furnished to the 
Company by the Initial Purchaser or such Holder expressly for use in the 
Registration Statement.  This indemnity will be in addition to any liability 
that the Initial Purchaser and such Holder might otherwise have; provided, 
however, that in no case shall the Initial Purchaser or any Holder be liable 
or responsible for any amount in excess of the net proceeds received by the 
Initial Purchaser or such Holder from the sale of Registrable Securities 
pursuant to the Registration Statement that gave rise to the indemnification 
claim pursuant to this Section 7(b).

          (c)  Any party that proposes to assert the right to be indemnified 
under this Section 7 will, promptly after receipt of notice of commencement 
of any action against such

                                        13

<PAGE>

party in respect of which a claim is to be made against an indemnifying party 
or parties under this Section 7, notify each such indemnifying party of the 
commencement of such action, enclosing a copy of all papers served, but the 
omission so to notify such indemnifying party will not relieve it from any 
liability that it may have to any indemnified party under the foregoing 
provisions of this Section 7 unless, and only to the extent that, such 
omission results in the forfeiture of substantive rights or defenses by the 
indemnifying party.  If any such action is brought against any indemnified 
party and it notifies the indemnifying party of its commencement, the 
indemnifying party will be entitled to participate in and, to the extent that 
it elects by delivering written notice to the indemnified party promptly 
after receiving notice of the commencement of the action from the indemnified 
party, jointly with any other indemnifying party similarly notified, to 
assume the defense of the action, with counsel reasonably satisfactory to the 
indemnified party, and after notice from the indemnifying party to the 
indemnified party of its election to assume the defense, the indemnifying 
party will not be liable to the indemnified party for any legal fees or other 
expenses of counsel in defending such action except as provided below and 
except for the reasonable costs of investigation subsequently incurred by the 
indemnified party in connection with the defense.  The indemnified party will 
have the right to employ its own counsel in any such action, but the fees, 
expenses and other charges of such counsel will be at the expense of such 
indemnified party unless (1) the employment of counsel by the indemnified 
party has been authorized in writing by the indemnifying party, (2) the 
indemnified party has reasonably concluded (based on advice of counsel) that 
there may be legal defenses available to it or other indemnified parties that 
are different from or in addition to those available to the indemnifying 
party, (3) a conflict or potential conflict exists (based on advice of 
counsel to the indemnified party) between the indemnified party and the 
indemnifying party (in which case the indemnifying party will not have the 
right to direct the defense of such action on behalf of the indemnified 
party) or (4) the indemnifying party has not in fact employed counsel to 
assume the defense of such action within a reasonable time after receiving 
notice of the commencement of the action, in each of which cases the 
reasonable fees, disbursements and other charges of counsel selected by the 
indemnified party will be at the expense of the indemnifying party or 
parties.  It is understood that the indemnifying party or parties shall not, 
in connection with any proceeding or related proceedings in the same 
jurisdiction, be liable for the reasonable fees, disbursements and other 
charges of more than one separate firm admitted to practice in such 
jurisdiction at any one time for all such indemnified parties not having 
actual or potential differing interests among themselves.  All such fees, 
disbursements and other charges will be reimbursed by the indemnifying party 
promptly as they are incurred.  An indemnifying party will not be liable for 
any settlement of any action or claim effected without its written consent 
(which consent will not be unreasonably withheld).  No indemnifying party 
shall, without the prior written consent of each indemnified party, settle or 
compromise or consent to the entry of any judgment in any pending or 
threatened claim, action or proceeding relating to the matters contemplated 
by this Section 7 (whether or not any indemnified party is a party thereto), 
unless such settlement, compromise or consent includes an unconditional 
release of each indemnified party from all liability arising or that may 
arise out of such claim, action or proceeding.

          (d)  In order to provide for just and equitable contribution in 
circumstances in which the indemnification provided for in the foregoing 
paragraphs of this Section 7 is applicable in accordance with its terms but 
for any reason is held to be unavailable from the Company on the one hand or 
the Initial Purchaser and such Holder on the other, the Company on the one 
hand and the Initial Purchaser and such Holder on the other will contribute 
to the total losses, claims, liabilities, expenses and damages (including any 
investigative, legal and other expenses reasonably incurred in connection 
with, and any amount paid in settlement of, any action, suit or proceeding or 
any claim asserted, but after deducting any contribution received by the 
Company from persons other than the Initial Purchaser and such Holder, such 
as persons who control the Company within the meaning of the Securities Act 
and directors of the Company, who also may be liable for contribution) to 
which the Company on the one hand and the Initial Purchaser and such Holders 
on the other may be subject in such proportion as shall be appropriate to 
reflect the relative benefits received by each.  The relative benefits 
received by the Company on the one hand and the Initial Purchaser on the 
other shall be deemed to be in the same proportion as the total net proceeds 
from the initial private placement by the Company (before deducting expenses) 
of the Registrable Securities received by the Company bear to the total fees 
received by the Initial Purchaser under the Purchase Agreement, in each case 
as set forth in the Registration Statement; the relative benefits received by 
the Company on the one hand and each Holder on the other shall be deemed to 
be in the same proportion as the total net proceeds from the initial private 
placement by the Company (before deducting expenses) of the Registrable 
Securities to which such losses, claims, damages or liabilities relate bears 
to the value to the Holder of receiving Registrable Securities that are 
registered under the Securities Act.  If, but only if, the allocation 
provided by the foregoing sentence is not permitted by applicable law, the 
allocation of contribution shall be made in such proportion as is appropriate 
to reflect not only the relative benefits referred to in the foregoing 
sentence but also the relative fault of the Company, on the one hand, and the 
Initial Purchaser or such Holder, on the other, with respect to the 
statements or omissions which resulted in such loss, claim, liability, 
expense or damage, or action in respect thereof, as well as any other 
relevant equitable considerations with respect to such private placement.  
Such relative fault shall be determined by reference to whether the untrue or 
alleged untrue statement of a material fact or omission or alleged omission 
to state a material fact relates to information supplied by the Company or 
the Initial Purchaser and such Holder, the intent of the parties and their 
relative knowledge, access to information and opportunity to correct or 
prevent such statement or omission. The Company, the Initial Purchaser and 
such Holder agree that it would not be just and equitable if contributions 
pursuant to this Section 7(d) were to be determined by pro rata allocation or 
by any other method of allocation which does not take into account the 
equitable considerations referred to herein.  The amount paid or payable by 
an indemnified party as a result of the loss, claim, liability, expense or 
damage, or action in respect thereof, referred to above in this Section 7(d) 
shall be deemed to include, for purpose of this Section 7(d), any legal or 
other expenses reasonably incurred by such indemnified party in connection 
with investigating or defending any such action or claim. Notwithstanding the 
provisions of this Section 7(d), the Initial Purchaser shall not be required 
to contribute any amount in excess of the fees received by it under the 
Purchase Agreement, no Holder shall be required to contribute any amount in 
excess of the net proceeds received by such Holder from the sale of the 
Registrable Securities that gave rise to the contribution 

                                        15

<PAGE>

obligation, and no person found guilty of fraudulent misrepresentation 
(within the meaning of Section 11(f) of the Securities Act) will be entitled 
to contribution from any person who was not guilty of such fraudulent 
misrepresentation.  For purposes of this Section 7(d), any person who 
controls a party to this Agreement or a Holder within the meaning of the 
Securities Act will have the same rights to contribution as that party, 
subject in each case to the provisions hereof.  Any party entitled to 
contribution, promptly after receipt of notice of commencement of any action 
against such party in respect of which a claim for contribution may be made 
under this Section 7(d), will notify any such party or parties from whom 
contribution may be sought, but the omission so to notify will not relieve 
the party or parties from whom contribution may be sought from any other 
obligation it or they may have under this Section 7(d).  No party will be 
liable for contribution with respect to any action or claim settled without 
its written consent (which consent will not be unreasonably withheld).

          (e)  The indemnity and contribution agreements contained in this 
Section 6 and the representations and warranties of the Company contained in 
this Agreement shall remain operative and in full force and effect regardless 
of (i) any investigation made by or on behalf of the Initial Purchaser or any 
Holder, (ii) acceptance of any of the Registrable Securities and payment 
therefor or (iii) any termination of this Agreement.  A successor to the 
Holder or any person controlling the Holder, or to the Company, its directors 
or officers, or any person controlling the Company, shall be entitled to the 
benefits of the indemnity, contribution and reimbursement agreements 
contained in this Section 7.

     SECTION 8.   INFORMATION REQUIREMENTS.  The Company shall file the 
reports required to be filed by it under the Exchange Act, and, if at any 
time before the end of the Effectiveness Period the Company is not subject to 
the reporting requirements of the Exchange Act, it will cooperate with any 
Holder of Registrable Securities and take such further reasonable action as 
any Holder of Registrable Securities may reasonably request (including, 
without limitation, making such reasonable representations as any such Holder 
may reasonably request), all to the extent required from time to time to 
enable such Holder to sell Registrable Securities without registration under 
the Securities Act within the limitation of the exemptions provided by Rule 
144 and Rule 144A.  Upon the request of any Holder of Registrable Securities, 
the Company shall deliver to such Holder a written statement as to whether it 
has complied with such filing requirements, unless such a statement has been 
included in the Company's most recent report required to be filed and filed 
pursuant to Section 13 or Section 15(d) of Exchange Act.  

     SECTION 9.   MISCELLANEOUS.

          (a)  NO CONFLICTING AGREEMENTS.  The Company has not entered, as of
the date hereof, nor shall it, on or after the date of this Agreement enter,
into any agreement with respect to its securities that conflicts with the rights
granted to the Holders in this Agreement.  The Company represents and warrants
that the rights granted to the Holders hereunder do not in any way conflict with
the rights granted to the holders of the Company's securities under any other
agreements.

supplemented, and waivers or consents to departures from the provisions 
hereof may not be given, unless the Company has obtained the written consent

Securities. Notwithstanding the foregoing, a waiver or consent to depart from 
the provisions hereof with respect to a matter that relates exclusively to 
the rights of Holders whose securities are being sold pursuant to a 
Registration Statement and that does not directly or indirectly affect the 
rights of other Holders may be given by Holders of at least a majority of the

          (d)  APPROVAL OF HOLDERS.  Whenever the consent or approval of 
Holders of a specified percentage of Registrable Securities is required 
hereunder, Registrable Securities held by the Company or its affiliates (as 
such term is defined in Rule 405 under the Securities Act) (other than the 
Initial Purchaser or subsequent Holders of Registrable Securities if such 
subsequent Holders are deemed to be such affiliates solely by reason of their 
holdings of such Registrable Securities) shall not be counted in determining 
whether such consent or approval was given by the Holders of such required 
percentage.

          (e)  SUCCESSORS AND ASSIGNS.  Any person who purchases any 
Registrable Securities from the Initial Purchaser shall be deemed, for 
purposes of this Agreement, to be an assignee of the Initial Purchaser.  This 
Agreement shall inure to the benefit of and be binding upon the successors 
and assigns of each of the parties and shall inure to the benefit of and be 
binding upon each Holder of any Registrable Securities.

          (f)  COUNTERPARTS.  This Agreement may be signed in two or more

                        ALEXANDRIA REAL ESTATE EQUITIES, INC.

                   SELLING SECURITYHOLDER NOTICE AND QUESTIONNAIRE

     The undersigned beneficial holder of shares of Common Stock, $.01 par 
value per share (the "REGISTRABLE SECURITIES"), of Alexandria Real Estate 
Equities, Inc. (the "COMPANY" or "REGISTRANT") understands that the 
Registrant has filed or intends to file with the Securities and Exchange 
Commission a registration statement on Form S-3 (as more fully defined in the 
Registration Rights Agreement referred to below, the "SHELF REGISTRATION 
STATEMENT") for the registration and resale under Rule 415 of the Securities 
Act of 1933, as amended (the "SECURITIES ACT"), of the Registrable 
Securities, in accordance with the terms of the Registration Rights 
Agreement, dated as of May 29, 1998 (the "REGISTRATION RIGHTS AGREEMENT"), 
between the Company and the Initial Purchaser named therein.  A copy of the 
Registration Rights Agreement is available from the Company upon request at 
the address set forth below.  Each capitalized term not otherwise defined 
herein shall have the meaning ascribed thereto in the Registration Rights 
Agreement.

     Each beneficial owner of Registrable Securities is entitled to the 
benefits of the Registration Rights Agreement.  In order to sell or otherwise 
dispose of any Registrable Securities pursuant to the Shelf Registration 
Statement, a beneficial owner of Registrable Securities generally will be 
required to be named as a selling securityholder in the related prospectus, 
deliver a prospectus to purchasers of Registrable Securities and be bound by 
those provisions of the Registration Rights Agreement applicable to such 
beneficial owner (including certain indemnification provisions, as described 
below). BENEFICIAL OWNERS THAT DO NOT COMPLETE THIS NOTICE AND QUESTIONNAIRE 
AND DELIVER IT TO THE COMPANY AS PROVIDED BELOW WILL NOT BE PERMITTED TO SELL 
ANY REGISTRABLE SECURITIES PURSUANT TO THE SHELF REGISTRATION STATEMENT.  
Beneficial owners are encouraged to complete and deliver this Notice and 
Questionnaire prior to the effectiveness of the Shelf Registration Statement 
so that such beneficial owners will be eligible to sell their Registrable 
Securities pursuant to the prospectus at the time of effectiveness.  Upon 
receipt of a completed Notice and Questionnaire from a beneficial owner 
following the effectiveness of the Shelf Registration Statement, the Company 
will, as promptly as practicable but in any event within seven Business Days 
of such receipt, file such amendments to the Shelf Registration Statement or 
supplements to the related prospectus as are necessary to permit such holder 
to deliver such prospectus to purchasers of Registrable Securities.

     Certain legal consequences arise from being named as a selling 
securityholder in the Shelf Registration Statement and related prospectus. 
Accordingly, holders and beneficial owners of Registrable Securities are 
advised to consult their own securities law counsel regarding the 
consequences of being named or not being named as a selling securityholder in 
the Shelf Registration Statement and related prospectus.
