NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share data)

Note 1.  Basis of Presentation

The accompanying consolidated financial statements of HRPT Properties Trust and its subsidiaries have been prepared without audit.  Certain information and footnote disclosures required by accounting principles generally accepted in the United States for complete financial statements have been condensed or omitted.  We believe the disclosures made are adequate to make the information presented not misleading.  However, the accompanying financial statements should be read in conjunction with the financial statements and notes contained in our Annual Report on Form 10-K for the year ended December 31, 2004.  In the opinion of management, all adjustments, which include only normal recurring adjustments considered necessary for a fair presentation, have been included.  All intercompany transactions and balances between HRPT Properties Trust and its subsidiaries have been eliminated.  Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.

Note 2.  Equity Investments

At March 31, 2005, and December 31, 2004, we had the following equity investments in Senior Housing Properties Trust, or Senior Housing, and Hospitality Properties Trust, or Hospitality Properties:

	Equity Investments				Equity in Earnings
	March 31, 2005		December 31, 2004		Three Months Ended March 31,
					2005		2004
Senior Housing	$	107,718	$	108,668	$	1,821	$	2,210
Hospitality Properties	97,829		99,136		1,573		1,590
	$	205,547	$	207,804	$	3,394	$	3,800

At March 31, 2005, we owned 8,660,738 common shares, or 12.6%, of Senior Housing with a carrying value of $107,718 and a market value, based on quoted market prices, of $144,461, and 4,000,000 common shares, or 6.0%, of Hospitality Properties with a carrying value of $97,829 and a market value, based on quoted market prices, of $161,520.  Our two managing trustees are also managing trustees of Senior Housing and Hospitality Properties and owners of Reit Management & Research LLC, or RMR, which is the investment manager to us, Senior Housing and Hospitality Properties.  We account for our investments in Senior Housing and Hospitality Properties using the equity method of accounting.

Note 3.  Real Estate Properties

During the three months ended March 31, 2005 and 2004, we funded $17,177 and $7,638, respectively, of improvements to our owned properties using cash on hand.

In February 2005 we completed diligence and committed to the acquisition of 8,200 square feet of industrial lands in Oahu, HI from the Estate of James Campbell and affiliates, for $115,500, plus closing costs.  The closing of this acquisition is expected to occur some time between June and December 2005.  In March 2005 we entered into a purchase agreement for a 628 square foot office property for $75,500 plus closing costs.  This potential acquisition is subject to our completion of due diligence and customary closing contingencies.  Because of these contingencies, we can provide no assurances that we will purchase this property.

Note 4.  Indebtedness

In January 2005 we amended our unsecured revolving credit facility to increase the available borrowing amount from $560,000 to $750,000 and to extend the maturity date from April 2006 to April 2009, with an option to extend the maturity by one additional year.  The annual interest payable for amounts drawn under the facility was reduced from LIBOR plus 0.80% to LIBOR plus 0.65%.  In certain circumstances, the amount of unsecured borrowings available under this facility may be increased to $1.5 billion.  Certain financial and other covenants in the facility were also amended to reflect current market conditions.  The interest rate on this facility averaged 3.2% and 1.9% per annum for the three months ended March 31, 2005 and 2004, respectively.  As of March 31, 2005, we had $80,000 outstanding on our revolving credit facility and $670,000 available for acquisitions and for general business purposes.  Our public debt indentures and credit facility and term loan agreements contain a number of financial and other covenants, including a credit facility and term loan covenant which limits the amount of aggregate distributions on common shares to 90% of operating cash flow available for shareholder distributions as defined in the credit facility and term loan agreements.

In February 2005 we repaid our $100,000 6.7% senior notes that were due in February 2005.  We funded this payment by drawing on our revolving credit facility.

Note 5.  Shareholders’ Equity

In March 2005 we issued 22,500,000 common shares in a public offering, raising net proceeds of $259,017.  Net proceeds from this offering were used to reduce amounts outstanding under our revolving credit facility.

Note 6.  Segment Information

Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and tables should be read in conjunction with our consolidated financial statements and notes thereto included in this quarterly report and our 2004 Annual Report on Form 10-K for the year ended December 31, 2004.

OVERVIEW

We primarily own office buildings located throughout the United States.  We also own approximately 10 million square feet of leased commercial and industrial lands located in Oahu, Hawaii and have minority holdings in shares of our former subsidiaries, Senior Housing and Hospitality Properties.

Property Operations

As of March 31, 2005, 93.7% of our total square feet was leased, compared to 93.2% leased as of March 31, 2004.  These results reflect a 1.2 percentage point increase at properties we owned continuously since January 1, 2004, partially offset by occupancy of approximately 90.1% at properties we acquired during 2004.  Occupancy data is as follows (square feet in thousands):

	All Properties				Comparable Properties (1)
	As of March 31,				As of March 31,
	2005		2004		2005		2004
Total properties	375		240		238		238
Total square feet	44,151		36,026		35,768		35,768
Percent leased (2)	93.7	%	93.2	%	94.3	%	93.1	%

(1)Based on properties owned continuously since January 1, 2004.

(2)Percent leased includes space being fitted out for occupancy pursuant to signed leases and space which is leased but is not occupied or is being offered for sublease by tenants.

During the past twelve months, the decline in occupancies at some of our continuously owned buildings which we previously experienced has stopped.  Also, quoted office rent rates in most of the areas where our properties are located seem to have stabilized.  However, we continue to experience strong competition to retain and attract office tenants in the form of landlord funded tenant build outs and increased leasing commissions payable to tenant brokers.  These build out costs and leasing commissions are generally amortized as a reduction of our income during the terms of the affected leases.  We do not know how long it may take the present market conditions affecting our properties to change.  At this time, however, we believe that modest declines in effective rents will continue to depress the financial results at some of our currently owned office buildings for at least one year.  There are too many variables for us to reasonably project what the financial impact of these market conditions will be on our results for future periods.

Results of operations and other operating data by property type for all properties is as follows (dollars and square feet in thousands):

During the first quarter of 2005 we signed new leases for 677,000 square feet and lease renewals for 829,000 square feet, at weighted average rental rates that were 11% lower than rents previously charged for the same space.  Average lease terms for leases signed during the first quarter of 2005 were 6.2 years.  Commitments for tenant improvement and leasing commission costs for leases signed during the first quarter of 2005 totaled $18.09 per square foot on a weighted average basis.  Rental rates at which available space may be relet in the future will depend on prevailing market conditions at that time.  Approximately 20% of our leased square feet are under leases scheduled to expire through December 31, 2007.  Lease expirations by property type as of March 31, 2005, are as follows (in thousands):

Financing Activities

In March 2005 we issued 22.5 million common shares in a public offering, raising net proceeds of $259.0 million.  Proceeds from this offering were used to repay amounts outstanding under our revolving credit facility.  In 2005 we also repaid our $100 million 6.7% unsecured senior notes when they became due in February 2005 using cash on hand and borrowings under our revolving credit facility.

Rental income.  Rental income increased for the three months ended March 31, 2005, compared to the same period in 2004, primarily due to our acquisition of 136 properties in 2004, partially offset by a decline in rents at some of our properties.  Rental income includes non cash straight line rent adjustments totaling $6.5 million in 2005 and $4.5 million in 2004 and amortization of acquired real estate leases and obligations totaling ($1.7) million in 2005 and $30,000 in 2004.  Rental income also includes lease termination fees totaling $150,000 in 2005 and $138,000 in 2004.

19

Total expenses.  Total expenses for the three months ended March 31, 2005, increased from the three months ended March 31, 2004, due to increases in operating expenses, depreciation and amortization and general and administrative expenses primarily related to the acquisition of properties in 2004.

Interest expense.  Interest expense increased for the three months ended March 31, 2005, compared to the three months ended March 31, 2004, reflecting an increase in total debt outstanding which was used primarily to finance acquisitions in 2004.  In 2004 we issued $400 million unsecured 6.25% senior notes due 2016; entered into an unsecured $350 million term loan bearing interest at LIBOR plus a premium; and assumed $112.3 million of debt in connection with two acquisitions.  The weighted average interest rate on all of our outstanding debt at March 31, 2005 and 2004, was 6.0% and 5.9%, respectively.

Loss on early extinguishment of debt.  The loss on early extinguishment of debt in 2004 represents the write off of deferred financing fees associated with the repayment of $143 million of our senior notes due 2013.

Equity in earnings of equity investments.  Equity in earnings of equity investments decreased during the three months ended March 31, 2005, from the three months ended March 31, 2004, due to lower earnings recognized from our investments in Senior Housing and Hospitality Properties.  The decrease in earnings from Senior Housing is due primarily to our sale in 2004 of 4.1 million Senior Housing common shares we owned.

Gain on sale of shares of equity investments.  The 2004 gain on sale of shares of equity investments reflects the sale during January and February 2004 of 3.1 million Senior Housing common shares we owned.

Gain on issuance of shares by equity investees.  The 2004 gain on issuance of shares by equity investees reflects the issuance of common shares during 2004 by both Senior Housing and Hospitality Properties at prices above our per share carrying value.

Net income and net income available for common shareholders.  The decrease in net income and net income available for common shareholders for the three months ended March 31, 2005, from the three months ended March 31, 2004, is due primarily to the gain on sale of Senior Housing shares and the gain on issuance of shares by equity investees, offset by a decrease in earnings from equity investments, the loss on early extinguishment of debt in 2004, and an increase in interest expense from the issuance of additional debt.  Net income available for common shareholders is net income reduced by preferred distributions.

LIQUIDITY AND CAPITAL RESOURCES

Our Operating Liquidity and Resources

Our principal sources of funds for current expenses and distributions to shareholders are rents from our properties and distributions received from our equity investments.  This flow of funds has historically been sufficient for us to pay our operating expenses, debt service and distributions.  We believe that our operating cash flow will be sufficient to meet our operating expenses, debt service and distribution payments for the foreseeable future.  Our future cash flows from operating activities will depend primarily upon four factors:

•our ability to maintain or improve occupancies and effective rent rates at our continuously owned properties;

•our ability to restrain operating cost increases at our properties;

•our continuing receipt of cash distributions from our equity investments; and

•our ability to purchase new properties which produce positive cash flows from operations.

20

As discussed above, we believe that present leasing market conditions in some areas where our properties are located may result in modest declines in effective rents at some of our properties for at least the next year.  Recent rises in fuel prices may cause our future operating costs to increase; however, the impact of these increases is expected to be partially offset by pass through operating cost increases to our tenants pursuant to lease terms.  We expect Hospitality Properties and Senior Housing to continue to pay dividends at current rates or with modest increases for the foreseeable future.  We generally do not engage in development activities (except on a build to suit basis for a tenant), and we generally do not purchase turn around properties or properties which do not generate positive cash flows.  Our future purchases of properties which generate positive cash flows can not be accurately projected because such purchases depend entirely upon available opportunities which come to our attention.

Cash flows provided by (used for) operating, investing and financing activities were $7.0 million, ($14.9) million and $8.3 million, respectively, for the three months ended March 31, 2005, and $30.0 million, $33.7 million and ($31.6) million, respectively, for the three months ended March 31, 2004.  Changes in all three categories between 2005 and 2004 are primarily related to the timing of payments for operating expenses, our sale of 3.1 million Senior Housing common shares in 2004, our repayments and issuances of debt obligations and our issuance of common shares in 2005 and 2004.

Our Investment and Financing Liquidity and Resources

In order to fund acquisitions and to accommodate cash needs that may result from timing differences between our receipt of rents and our desire or need to make distributions or pay operating expenses, we maintain an unsecured revolving credit facility with a group of commercial banks.  At March 31, 2005, there was $80 million outstanding and $670 million available under our revolving credit facility, and we had cash and cash equivalents of $22.3 million.  We expect to use cash balances, borrowings under our credit facility and net proceeds of offerings of equity or debt securities to fund future property acquisitions.

When amounts are outstanding on our revolving credit facility and as the maturity dates of our revolving credit facility and term debts approach, we explore alternatives for the repayment of amounts due.  Such alternatives usually include incurring additional term debt and issuing new equity securities.  As of March 31, 2005, we had $2.0 billion available on an effective shelf registration statement.  An effective shelf registration statement allows us to issue public securities on an expedited basis, but it does not assure that there will be buyers for such securities.  Although there can be no assurance that we will consummate any debt or equity offerings or other financings, we believe we will have access to various types of financing, including debt or equity offerings, with which to finance future acquisitions and to pay our debt and other obligations.

The completion and the costs of our future debt transactions will depend primarily upon market conditions and our own credit ratings.  We have no control over market conditions, but we expect both short and long term debt costs to increase gradually for at least the next few months.  Our credit ratings depend upon evaluations by credit rating agencies of our business practices and plans and, in particular, whether we appear to have the ability to maintain our earnings, to space our debt maturities and to balance our use of debt and equity capital so that our financial performance and leverage ratios afford us flexibility to withstand any reasonably anticipatable adverse changes.  We intend to conduct our business activities in a manner which will continue to afford us reasonable access to capital for investment and financing activities.

During 2005 we funded improvements to our owned properties totaling $17.2 million using cash on hand.  During February 2005 we completed diligence and committed to the acquisition of 8.2 million square feet of industrial lands in Oahu, HI for $115.5 million, plus closing costs.  In March 2005 we entered into a purchase agreement for a 628,000 square foot office property for $75.5 million plus closing costs.  While the closing of these acquisitions are expected to occur before December of 2005, there can be no assurance that they will close or that closing will not be delayed.

During the three months ended March 31, 2005 and 2004, cash expenditures made and capitalized for tenant improvements, leasing costs, building improvements and development and redevelopment activities were as follows (in thousands):

	Three Months Ended March 31,

Commitments made for expenditures in connection with leasing space during the three months ended March 31, 2005, are as follows (in thousands, except as noted):

	Total		Renewals		New Leases

Average lease term (years)	6.2		6.7		5.5
Leasing costs per square foot per year (whole dollars)	$	2.92	$	2.23	$	3.99

At March 31, 2005, we owned 8.7 million, or 12.6%, of the common shares of Senior Housing with a carrying value of $107.7 million and a market value, based on quoted market prices, of $144.5 million, and 4.0 million, or 6.0%, of the common shares of Hospitality Properties with a carrying value of $97.8 million and a market value, based on quoted market prices, of $161.5 million.  During the three months ended March 31, 2005, we received cash distributions totaling $2.8 million from Senior Housing and $2.9 million from Hospitality Properties.  We use the income statement method to account for the issuance of common shares by Senior Housing and Hospitality Properties.  Under this method, gains and losses reflecting changes in the value of our investments at the date of issuance of additional common shares by Senior Housing and Hospitality Properties are recognized in our income statement.  On May 5, 2005, the market values of our Senior Housing and Hospitality Properties shares were $154.2 million and $170.1 million, respectively.  In the future we may decide to sell some or all of our remaining Hospitality Properties or Senior Housing shares, based upon several factors including available uses for the sale proceeds and the prices at which sales may be accomplished.

In March 2005 we issued 22.5 million common shares in a public offering at $12.10 per share, raising gross proceeds of $272.3 million.  Net proceeds of this offering, totaling $259.0 million, were used to reduce amounts outstanding under our revolving credit facility.

In January 2005 we amended our unsecured revolving credit facility to increase the available borrowing amount from $560 million to $750 million and to extend the maturity date from April 2006 to April 2009, with an option to extend the maturity by one additional year.  The annual interest payable for amounts drawn under the facility was reduced from LIBOR plus 0.80% to LIBOR plus 0.65%.  In certain circumstances, the amount of unsecured borrowings available under this facility may be increased to $1.5 billion.  Certain financial and other covenants in the facility were also amended to reflect current market conditions.  The interest rate averaged 3.2% per annum for the three months ended March 31, 2005.  As of March 31, 2005, we had $80 million outstanding under our revolving credit facility and $670 million available for acquisitions and for general business purposes.  In February 2005 we repaid our $100 million 6.7% senior notes when they became due in February 2005.  We funded this payment with cash on hand and by drawing on our revolving credit facility.

As of March 31, 2005, our contractual obligations were as follows (dollars in thousands):

	Payment due by period

Long-Term Debt Obligations	$	2,170,982	$	7,625	$	31,003	$	466,145	$	1,666,209

(1)Committed tenant related obligations include leasing commissions and tenant improvements and are based on leases executed as of March 31, 2005.

(2)   Represents the purchase price to acquire 8.2 million square feet of industrial lands in Oahu, HI for $115.5 million as agreed to in February 2005, plus a 628,000 square foot office property for $75.5 million as agreed to in March 2005.

(3)   Projected interest expense is attributable to only the long term debt obligations listed above at existing rates and is not intended to project future interest costs which may result from debt prepayments, new debt issuances or changes in interest rates.

As of March 31, 2005, we have no commercial paper, derivatives, swaps, hedges, guarantees, material joint ventures or off balance sheet arrangements.  None of our debt documentation requires us to provide collateral security in the event of a ratings downgrade.

Debt Covenants

Our principal debt obligations at March 31, 2005, were our unsecured revolving credit facility, our unsecured $350 million term loan and our $1.3 billion of publicly issued term debt.  Our publicly issued debt is governed by an indenture.  This indenture and related supplements, our revolving credit facility agreement and our term loan agreement contain a number of financial ratio covenants which generally restrict our ability to incur debts, including debts secured by mortgages on our properties in excess of calculated amounts, require us to maintain a minimum net worth, restrict our ability to make distributions under certain circumstances and require us to maintain other ratios.  At March 31, 2005, we were in compliance with all of our covenants under our indenture and related supplements, our term loan agreement and our revolving credit facility agreement.

In addition to our unsecured debt obligations, we have $441.0 million of mortgage notes outstanding at March 31, 2005.

None of our indenture and related supplements, our revolving credit facility, our term loan agreement or our mortgage notes contain provisions for acceleration which could be triggered by our debt ratings.  However, our senior debt rating is used to determine the interest rate payable under our revolving credit facility and our term loan agreement, and the fees payable under our revolving credit facility.

Our public debt indenture and related supplements contain cross default provisions to any other debts of $20 million or more.  Similarly, a default on our public debt indenture would be a default under our revolving credit and term loan facilities.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

We are exposed to risks associated with market changes in interest rates.  Our strategy to manage exposure to changes in interest rates is unchanged since December 31, 2004.  Other than as described below, we do not foresee any significant changes in our exposure to fluctuations in interest rates or in how we manage this exposure in the near future.

Our unsecured revolving credit facility and our unsecured bank term loan bear interest at floating rates and mature in April 2009.  As of March 31, 2005, we had $80 million outstanding and $670 million available for drawing under our revolving credit facility and $350 million outstanding under our bank term loan.  Repayments under our revolving credit facility may be made at any time without penalty.  Repayments under our bank term loan may be made without penalty beginning in February 2006.  We borrow in U.S. dollars and borrowings under our revolving credit facility and our bank term loan require interest at LIBOR plus a premium.  Accordingly, we are vulnerable to changes in U.S. dollar based short term rates, specifically LIBOR.  A change in interest rates would not affect the value of these floating rate debts but would affect our operating results.  For example, the average interest rate payable on our $350 million term loan and $80 million outstanding on our revolving credit facility at March 31, 2005, was 3.3% per annum.  The following table presents the impact a 10% change in interest rates would have on our floating rate interest expense as of March 31, 2005 (dollars in thousands):

	Impact of Changes in Interest Rates
	Interest Rate Per Year		Outstanding Debt		Total Interest Expense Per Year
At March 31, 2005	3.3	%	$	430,000	$	14,190
10% reduction	3.0	%	$	430,000	$	12,900
10% increase	3.6	%	$	430,000	$	15,480

The foregoing table shows the impact of an immediate change in floating interest rates.  If interest rates were to change gradually over time, the impact would be spread over time.  Our exposure to fluctuations in floating interest rates will increase or decrease in the future with increases or decreases in the outstanding amount of our floating rate debt.

Our $1.3 billion of publicly issued term debt and our $441.0 million of mortgage notes outstanding on March 31, 2005, bear interest at fixed rates.  Changes in market interest rates during the terms of this debt will not affect our operating results.  If all of our fixed rate unsecured and secured notes outstanding at March 31, 2005, were to be refinanced at interest rates which are 10% higher or lower than current interest rates, our per annum interest cost would increase or decrease, respectively, by approximately $11.6 million.

Item 4.  Controls and Procedures

As of the end of the period covered by this report, our management carried out an evaluation, under the supervision and with the participation of our managing trustees, President and Chief Operating Officer and Treasurer and Chief Financial Officer of the effectiveness of our disclosure controls and procedures pursuant to Exchange Act Rules 13a-15 and 15d-15. Based upon that evaluation, our managing trustees, President and Chief Operating Officer and Treasurer and Chief Financial Officer concluded that our disclosure controls and procedures are effective.

There have been no changes in our internal control over financial reporting during the quarter ended March 31, 2005, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

AND OTHER MATTERS.  ALSO, WHENEVER WE USE WORDS SUCH AS “BELIEVE”, “EXPECT”, “ANTICIPATE”, “INTEND”, “PLAN”, “ESTIMATE” OR SIMILAR EXPRESSIONS, WE ARE MAKING FORWARD LOOKING STATEMENTS.

ACTUAL RESULTS MAY DIFFER MATERIALLY FROM THOSE CONTAINED IN OR IMPLIED BY THE FORWARD LOOKING STATEMENTS AS A RESULT OF VARIOUS FACTORS.  SUCH FACTORS INCLUDE, WITHOUT LIMITATION,

•CHANGES IN THE ECONOMY AND THE CAPITAL MARKETS,

•COMPETITION WITHIN THE REAL ESTATE INDUSTRY OR THOSE INDUSTRIES IN WHICH OUR TENANTS AND FORMER SUBSIDIARIES OPERATE, AND

•CHANGES IN FEDERAL, STATE AND LOCAL LEGISLATION.

FOR EXAMPLE:

•SOME OF OUR TENANTS MAY NOT RENEW EXPIRING LEASES, AND WE MAY BE UNABLE TO LOCATE NEW TENANTS TO MAINTAIN THE HISTORICAL OCCUPANCY RATES OF OUR PROPERTIES,

•RENTS THAT WE CAN CHARGE AT OUR PROPERTIES MAY DECLINE,

•OUR TENANTS MAY EXPERIENCE LOSSES AND BECOME UNABLE TO PAY OUR RENTS,

•THE DIVIDENDS WE RECEIVE FROM OUR FORMER SUBSIDIARIES MAY DECLINE OR WE MAY BE UNABLE TO SELL OUR SHARES IN OUR FORMER SUBSIDIARIES FOR AMOUNTS EQUAL TO OUR CARRYING VALUES OF THOSE SHARES,

•CHANGES IN CIRCUMSTANCES COULD CAUSE THE CLOSING OF OUR ACQUISITION OF THE CAMPBELL LANDS AND OTHER COMMITTED TRANSACTIONS NOT TO

27

OCCUR OR BE DELAYED.  THIS RESULT COULD OCCUR DUE TO VARIOUS CIRCUMSTANCES WHICH ARE BEYOND OUR CONTROL.  FOR EXAMPLE, WE WILL REQUIRE UPDATES OF VARIOUS DILIGENCE ITEMS IF THE CLOSING OF THE CAMPBELL LANDS IS DELAYED FOR MORE THAN A SHORT PERIOD, AND THOSE UPDATES MAY CAUSE THE TRANSACTION TO FAIL TO CLOSE, AND

•WE MAY BE UNABLE TO IDENTIFY PROPERTIES WHICH WE WANT TO BUY OR TO NEGOTIATE ACCEPTABLE PURCHASE PRICES.

THESE RESULTS COULD OCCUR DUE TO MANY DIFFERENT CIRCUMSTANCES, SOME OF WHICH, SUCH AS CHANGES IN OUR TENANTS’ FINANCIAL CONDITIONS OR NEEDS FOR LEASED SPACE, OR CHANGES IN THE CAPITAL MARKETS OR THE ECONOMY GENERALLY, ARE BEYOND OUR CONTROL.  SIMILARLY, OUR IMPLEMENTATION OF FAS 141 HAS REQUIRED US TO MAKE JUDGMENTS ABOUT THE ALLOCATION OF THE PURCHASE PRICES OF OUR PROPERTIES WHICH AFFECT OUR FINANCIAL STATEMENTS, INCLUDING FUTURE INCOME; THESE JUDGMENTS ARE BASED UPON OUR ESTIMATES, BELIEFS AND EXPECTATIONS ABOUT VACANT BUILDING VALUES AND RENTAL RATES, BUT SUCH ESTIMATES, BELIEFS AND EXPECTATIONS MAY PROVE TO BE INACCURATE.  THE INFORMATION CONTAINED ELSEWHERE IN THIS QUARTERLY REPORT ON FORM 10-Q IDENTIFY OTHER IMPORTANT FACTORS THAT COULD CAUSE SUCH DIFFERENCES.

FORWARD LOOKING STATEMENTS ARE ONLY EXPRESSIONS OF OUR PRESENT EXPECTATIONS AND INTENTIONS.  FORWARD LOOKING STATEMENTS ARE NOT GUARANTEED TO OCCUR AND MAY NOT OCCUR.  YOU SHOULD NOT PLACE UNDUE RELIANCE UPON FORWARD LOOKING STATEMENTS.   EXCEPT AS MAY BE REQUIRED BY LAW, WE DO NOT INTEND TO IMPLY THAT WE WILL UPDATE OR REVISE ANY FORWARD LOOKING STATEMENTS AS A RESULT OF NEW INFORMATION, FUTURE EVENTS OR OTHERWISE.
