1.               ORGANIZATION

Extra Space Storage Inc. (the “Company”) is a self-administered and self-managed real estate investment trust (“REIT”), formed as a Maryland corporation on April 30, 2004 to own, operate, manage, acquire and develop self-storage facilities located throughout the United States. The Company continues the business of Extra Space Storage LLC and its subsidiaries, which had engaged in the self-storage business since 1977. The Company’s interest in its properties is held through its operating partnership, Extra Space Storage LP (the “Operating Partnership”), which was formed on May 5, 2004. The Company’s primary assets are general partner and limited partner interests in the Operating Partnership. This structure is commonly referred to as an umbrella partnership REIT, or UPREIT. The Company has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). To the extent the Company continues to qualify as a REIT, it will not be subject to tax, with certain limited exceptions, on the taxable income that is distributed to its stockholders.

The Company invests in self-storage facilities by acquiring or developing wholly-owned facilities or by acquiring an equity interest in real estate entities.  At March 31, 2008, the Company had direct and indirect equity interests in 607 storage facilities located in 33 states and Washington, D.C.  In addition, the Company managed 47 properties for franchisees and third parties, bringing the total number of properties which it owns and/or manages to 654.

The Company operates in two distinct segments: (1) property management, acquisition and development; and (2) rental operations. The Company’s property management, acquisition and development activities include managing, acquiring, developing and selling self-storage facilities. The rental operations activities include rental operations of self-storage facilities. No single tenant accounts for more than 5% of rental income.

2.              BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements of the Company are presented on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they may not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2008 are not necessarily indicative of results that may be expected for the year ended December 31, 2008. The Condensed Consolidated Balance Sheet as of December 31, 2007 has been derived from the Company’s audited financial statements as of that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2007 as filed with the Securities and Exchange Commission (“SEC”).

Reclassifications

Certain amounts in the 2007 financial statements and supporting note disclosures have been reclassified to conform to the current year presentation.  Such reclassification did not impact previously reported net income or accumulated deficit.

Recently Issued Accounting Standards

In September 2006, the Financial Accounting Standards Board (“FASB”) issued Statement No. 157, “Fair Value Measurements” (“FAS 157”).  FAS 157 defines fair value, establishes guidelines for measuring fair value and expands disclosures regarding fair value measurements.  FAS 157 applies under other accounting pronouncements that require or permit fair value measurements, and does not require any new fair value measurements.  FAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years.  In February 2008, the FASB issued FASB Statement of Position No. 157-2, “Effective Date of FASB Statement No. 157” (the “FSP”).  The FSP amends FAS 157 to delay the effective date for FAS 157 for nonfinancial assets and nonfinancial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis.  For items within that scope, the FSP defers the effective date of FAS 157 to fiscal years beginning after November 15, 2008 and

8

interim periods within those fiscal years.  The Company adopted FAS 157 effective January 1, 2008, except as it relates to nonfinancial assets and liabilities that are not recognized or disclosed at fair value in the financial statements on a recurring basis as allowed under the FSP.

In February 2007, the FASB issued Statement No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities”  (“FAS 159”).  Under FAS 159, a company may elect to measure eligible financial assets and financial liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings at each subsequent reporting date.  This statement is effective for fiscal years beginning after November 15, 2007.  The Company adopted FAS 159 effective January 1, 2008, but did not elect to measure any additional financial assets or liabilities at fair value.

In December 2007, the FASB issued revised Statement No. 141, “Business Combinations” (“FAS 141(R)”).  FAS 141(R) establishes principles and requirements for how an acquirer in a business combination recognizes and measures in its financial statements the assets acquired and liabilities assumed.  Generally, assets acquired and liabilities assumed in a transaction will be recorded at the acquisition-date fair value with limited exceptions.  FAS 141(R) will also change the accounting treatment and disclosure for certain specific items in a business combination.  FAS 141(R) applies proactively to business combinations for which the acquisition date is on or after the beginning of the first fiscal year beginning on or after December 15, 2008.  The Company will assess the impact of FAS 141(R) if and when future acquisitions occur.  However, the application of FAS 141(R) will result in a significant change in accounting for future acquisitions after the effective date.

In December 2007, the FASB issued Statement No. 160, “Noncontrolling Interests in Consolidated Financial Statements – An Amendment of ARB No. 51” (“FAS 160”).  FAS 160 establishes new accounting and reporting standards for the non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary.  FAS 160 is effective for fiscal years beginning on or after December 15, 2008.  The Company does not currently expect the adoption of FAS 160 to have a material impact on its financial statements.

In March 2008, the FASB issued SFAS No. 161, “Disclosures about Derivatives Instruments and Hedging Activities”, an amendment of FASB Statement No. 133, “Accounting for Derivative Instruments and Hedging Activities” (“FAS 161”). FAS 161 changes the disclosure requirements for derivative instruments and hedging activities. Entities are required to provide enhanced disclosures stating how and why an entity uses derivative instruments; how derivative instruments and related hedged items are accounted for under SFAS No. 133 and its related interpretations; and how derivative instruments and related hedged items affect an entity’s financial position, financial performance and cash flows. FAS 161 requires that objectives for using derivative instruments be disclosed in terms of underlying risk and accounting designation. FAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged.  FAS 161 also encourages but does not require comparative disclosures for earlier periods at initial adoptions. The Company is currently evaluating whether the adoption of FAS 161 will have an impact on its financial statements.

In December 2007, the Securities and Exchange Commission (“SEC”) staff issued Staff Accounting Bulletin (“SAB”) No. 110, which is effective January 1, 2008 and amends and replaces SAB No. 107, “Share-Based Payment”. SAB No. 110 expresses the views of the SEC staff regarding the use of a “simplified” method in developing an estimate of expected term of “plain vanilla” share options in accordance with SFAS No. 123(R), “Share-Based Payment”. Under the “simplified” method, the expected term is calculated as the midpoint between the vesting date and the end of the contractual term of the option. The use of the “simplified” method, which was first described in SAB No. 107, was scheduled to expire on December 31, 2007. SAB No. 110 extends the use of the “simplified” method for “plain vanilla” awards in certain situations. The SEC staff does not expect the “simplified” method to be used when sufficient information regarding exercise behavior, such as historical exercise data or exercise information from external sources, becomes available. The adoption of SAB No. 110 did not have a significant effect on the Company’s financial statements.

Fair Value Disclosures

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table provides information for each major category of assets and liabilities that are measured at fair value on a recurring basis:

9

Following is a reconciliation of the beginning and ending balances for the Company’s investments available for sale, which were the Company’s only material assets or liabilities that are remeasured on a recurring basis using significant unobservable inputs (Level 3):

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Long-lived assets held for use are evaluated for impairment when events or circumstances indicate there may be impairment.  When such an event occurs, the Company compares the carrying value of these long-lived assets to the undiscounted future net operating cash flows attributable to the assets.  An impairment loss is recorded if the net carrying value of the assets exceeds the undiscounted future net operating cash flows attributable to the asset.  The impairment loss recognized equals the excess of net carrying value over the related fair value of the asset.  The Company has determined that no property was impaired and therefore no impairment charges were recorded during the three months ended March 31, 2008 or 2007.

When real estate assets are identified as held for sale, the Company discontinues depreciating the assets and estimates the fair value of the assets, net of selling costs.  If the estimated fair value, net of selling costs, of the assets that have been identified as held for sale is less than the net carrying value of the assets, then a valuation allowance is established.  The operations of assets held for sale or sold during the period are presented as discontinued operations for all periods presented.  The Company did not have any properties classified as held for sale at March 31, 2008.

The Company assesses whether there are any indicators that the value of its investments in unconsolidated real estate ventures may be impaired when events or circumstances indicate there may be an impairment.  An investment is impaired if the Company’s estimate of the fair value of the investment is less than its carrying value.  To the extent impairment has occurred, and is considered to be other-than-temporary, the loss is measured as the excess of the carrying amount over the fair value of the investment.  No impairment charges were recognized for the three months ended March 31, 2008 or 2007.

There were no impaired properties or investments in unconsolidated real estate ventures or any real estate assets identified as held for sale during the three months ended March 31, 2008. Therefore, the Company did not make any nonrecurring fair value measurements during the period.

3.              NET INCOME PER SHARE

Basic earnings per common share is computed by dividing net income by the weighted average common shares outstanding, less non-vested restricted stock. Diluted earnings per common share measures the performance of the Company over the reporting period while giving effect to all potential common shares that were dilutive and outstanding during the period. The denominator includes the number of additional common shares that would have been outstanding if the potential common shares that were dilutive had been issued and is calculated using either the treasury stock or if-converted method. Potential

10

common shares are securities (such as options, warrants, convertible debt, Contingent Conversion Shares (“CCSs”), Contingent Conversion Units (“CCUs”), exchangeable Series A Participating Redeemable Preferred Operating Partnership units (“Preferred OP units”) and exchangeable Operating Partnership units (“OP units”) that do not have a current right to participate in earnings but could do so in the future by virtue of their option or conversion right. In computing the dilutive effect of convertible securities, net income is adjusted to add back any changes in earnings in the period associated with the convertible security. The numerator also is adjusted for the effects of any other non-discretionary changes in income or loss that would result from the assumed conversion of those potential common shares. In computing diluted earnings per share, only potential common shares that are dilutive, or reduce earnings per share, are included.

The Company’s Operating Partnership has $250,000 of exchangeable senior notes issued and outstanding that also can potentially have a dilutive effect on its earnings per share calculations. The exchangeable senior notes are exchangeable by holders into shares of the Company’s common stock under certain circumstances per the terms of the indenture governing the exchangeable senior notes. The exchangeable senior notes are not exchangeable unless the price of the Company’s common stock is greater than or equal to 130% of the applicable exchange price for a specified period during a quarter, or unless certain other events occur. The exchange price was $23.45 per share at March 31, 2008, and could change over time as described in the indenture. The price of the Company’s common stock did not exceed 130% of the exchange price for the specified period of time during the first quarter of 2008; therefore holders of the exchangeable senior notes may not elect to convert them during the second quarter of 2008.

The Company has irrevocably agreed to pay only cash for the accreted principal amount of the exchangeable senior notes relative to its exchange obligations, but has retained the right to satisfy the exchange obligations in excess of the accreted principal amount in cash and/or common stock. Though the Company has retained that right, FASB Statement No. 128 “Earnings per Share,” (“FAS 128”) requires an assumption that shares will be used to pay the exchange obligations in excess of the accreted principal amount, and requires that those shares be included in the Company’s calculation of weighted average common shares outstanding for the diluted earnings per share computation. No shares were included in the computation at March 31, 2008 because there was no excess over the accreted principal for the period.

For the purposes of computing the diluted impact on earnings per share of the potential conversion of Preferred OP units into common shares, where the Company has the option to redeem in cash or shares as discussed in Note 14 and where the Company has stated the positive intent and ability to settle at least $115,000 of the instrument in cash (or net settle a portion of the Preferred OP units against the related outstanding note receivable), only the amount of the instrument in excess of $115,000 is considered in the calculation of shares contingently issuable for the purposes of computing diluted earnings per share as allowed by paragraph 29 of FAS 128.

For the three months ended March 31, 2008 and 2007, options to purchase approximately 1,441,469 and 89,642 shares of common stock, respectively, were excluded from the computation of earnings per share as their effect would have been anti-dilutive.

The computation of net income per share is as follows:

4.              REAL ESTATE ASSETS

The components of real estate assets are summarized as follows:

5.              INVESTMENTS IN REAL ESTATE VENTURES

Investments in real estate ventures consisted of the following:

In these joint ventures, the Company and the joint venture partner generally receive a preferred return on their invested capital. To the extent that cash/profits in excess of these preferred returns are generated through operations or capital transactions, the Company would receive a higher percentage of the excess cash/profits than its equity interest.

The components of equity in earnings of real estate ventures consist of the following:

12

Equity in earnings (losses) of ESW II, SP I and SPB II include the amortization of the Company’s excess purchase price of $25,713 of these equity investments over its original basis. The excess basis is amortized over 40 years.

6.              INVESTMENTS AVAILABLE-FOR-SALE

The Company accounts for its investments in debt and equity securities according to the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 115, “Accounting for Certain Investments in Debt and Equity Securities”, which requires securities classified as “available for sale” to be stated at fair value. Adjustments to fair value of available for sale securities are recorded as a component of other comprehensive loss.  A decline in the market value of equity securities below cost, that is deemed to be other than temporary, results in a reduction in the carrying amount to fair value.  The impairment is charged to earnings and a new cost basis for the security is established.  The Company’s investments available-for-sale have generally consisted of non mortgage-backed auction rate securities (“ARS”).  ARS are generally long-term debt instruments that provide liquidity through a Dutch auction process that resets the applicable interest rate at pre-determined calendar intervals, generally every 28 days.  This mechanism allows existing investors to rollover their holdings and continue to own their respective securities or liquidate their holding by selling their securities at par.

The recent uncertainties in the credit markets had prevented the Company and other investors from liquidating their holdings of ARS in recent auctions for these securities because the amount of securities submitted for sale has exceeded the amount of purchase orders.  As a result, during the year ended December 31, 2007, the Company recognized an other-than-temporary impairment charge of $1,213 and temporary impairment charge of $1,415, which reduced the carrying value of the Company’s investments in ARS to $21,812 as of December 31, 2007.  On February 29, 2008, the Company liquidated its holdings of ARS for $21,812 in cash.  As a result of this settlement, the Company recognized $1,415 of the amount that was previously classified as a temporary impairment as loss on sale of investments available for sale through earnings.  The Company had no investments in ARS as of March 31, 2008.

7.              OTHER ASSETS

The components of other assets are summarized as follows:

13

8.              NOTES PAYABLE

The components of notes payable are summarized as follows:

Real estate assets are pledged as collateral for the notes payable. The Company is subject to certain restrictive covenants relating to the outstanding notes payable. The Company was in compliance with all covenants at March 31, 2008.

In October 2004, the Company entered into a reverse interest rate swap agreement (“Swap Agreement”) to float $61,770 of 4.30% fixed interest rate secured notes due in September 2009. Under this Swap Agreement, the Company will receive interest at a fixed rate of 4.30% and pay interest at a variable rate equal to LIBOR plus 0.66%. The Swap Agreement matures at the same time the notes are due. This Swap Agreement is a fair value hedge, as defined by SFAS No. 133, and the fair value of the Swap Agreement is recorded as an asset or liability, with an offsetting adjustment to the carrying value of the related note payable. Monthly variable interest payments are recognized as an increase or decrease in interest expense.

The estimated fair value of the Swap Agreement at March 31, 2008 was reflected as an other asset of $997.  The estimated fair value of the Swap Agreement at December 31, 2007 was reflected as an other liability of $125.  The fair value of the Swap Agreement is determined through observable prices in active markets for identical agreements.  For the three months ended March 31, 2008 and 2007, interest expense has been increased by $112 and $261, respectively, as a result of the Swap Agreement.

On August 31, 2007, as part of the acquisition of a partner’s joint venture interest in seven properties, the Company assumed an interest rate cap agreement related to the assumption of the loan on these properties.  The Company has designated the interest rate cap agreement as a cash flow hedge of the interest payments resulting from an increase in the interest rates above the rates designated in the interest rate cap agreement.  The interest rate cap agreement will allow increases in interest payments based on an increase in the LIBOR rate above the capped rates (5.19% from 1/1/2007 to 12/31/2007 and 5.48% from 1/1/2008 through 12/31/2008) on $23,340 of floating rate debt to be offset by the value of the interest rate cap agreement.  The estimated fair value of the interest rate cap at the assumption date was not material and no asset or liability was recorded.  The fair value of the interest rate cap at March 31, 2008 and December 31, 2007 was also not material.  The fair value of the interest rate cap is determined through observable prices in active markets for identical agreements.

9.              NOTES PAYABLE TO TRUSTS

During July 2005, ESS Statutory Trust III (the “Trust III”), a newly formed Delaware statutory trust and a wholly-owned, unconsolidated subsidiary of the Operating Partnership, issued an aggregate of $40,000 of preferred securities which mature

14

on July 31, 2035. In addition, the Trust III issued 1,238 of Trust common securities to the Operating Partnership for a purchase price of $1,238. On July 27, 2005, the proceeds from the sale of the preferred and common securities of $41,238 were loaned in the form of a note to the Operating Partnership (“Note 3”). Note 3 has a fixed rate of 6.91% through July 31, 2010, and then will be payable at a variable rate equal to the three-month LIBOR plus 2.40% per annum. The interest on Note 3, payable quarterly, will be used by the Trust III to pay dividends on the trust preferred securities. The trust preferred securities may be redeemed by the Trust with no prepayment premium after July 27, 2010.

During May 2005, ESS Statutory Trust II (the “Trust II”), a newly formed Delaware statutory trust and a wholly-owned, unconsolidated subsidiary of the Operating Partnership, issued an aggregate of $41,000 of preferred securities which mature on June 30, 2035. In addition, the Trust II issued 1,269 of Trust common securities to the Operating Partnership for a purchase price of $1,269. On May 24, 2005, the proceeds from the sale of the preferred and common securities of $42,269 were loaned in the form of a note to the Operating Partnership (“Note 2”). Note 2 has a fixed rate of 6.67% through June 30, 2010, and then will be payable at a variable rate equal to the three-month LIBOR plus 2.40% per annum. The interest on Note 2, payable quarterly, will be used by the Trust II to pay dividends on the trust preferred securities. The trust preferred securities may be redeemed by the Trust with no prepayment premium after June 30, 2010.

During April 2005, ESS Statutory Trust I (the “Trust”), a newly formed Delaware statutory trust and a wholly-owned, unconsolidated subsidiary of the Operating Partnership issued an aggregate of $35,000 of trust preferred securities which mature on June 30, 2035. In addition, the Trust issued 1,083 of trust common securities to the Operating Partnership for a purchase price of $1,083. On April 8, 2005, the proceeds from the sale of the trust preferred and common securities of $36,083 were loaned in the form of a note to the Operating Partnership (the “Note”). The Note has a variable rate equal to the three-month LIBOR plus 2.25% per annum. The interest on the Note, payable quarterly, will be used by the Trust to pay dividends on the trust preferred securities. The trust preferred securities may be redeemed by the Trust with no prepayment premium after June 30, 2010.

The Company follows FASB Interpretation No. 46R, “Consolidation of Variable Interest Entities” (“FIN 46R”), which addresses the consolidation of variable interest entities (“VIEs”).  Under FIN 46R, Trust, Trust II and Trust III are VIEs that are not consolidated because the Company is not the primary beneficiary. A debt obligation has been recorded in the form of notes as discussed above for the proceeds, which are owed to the Trust, Trust II, and Trust III by the Company.

10.       EXCHANGEABLE SENIOR NOTES

On March 27, 2007, our Operating Partnership issued $250,000 of its 3.625% Exchangeable Senior Notes due April 1, 2027 (the “Notes”). Costs incurred to issue the Notes were approximately $5,100. These costs are being amortized over five years, which represents the estimated term of the Notes, and are included in other assets in the condensed consolidated balance sheet as of March 31, 2008. The Notes are general unsecured senior obligations of the Operating Partnership and are fully guaranteed by the Company. Interest is payable on April 1 and October 1 of each year beginning until the maturity date of April 1, 2027. The Notes bear interest at 3.625% per annum and contain an exchange settlement feature, which provides that the Notes may, under certain circumstances, be exchangeable for cash (up to the principal amount of the Notes) and, with respect to any excess exchange value, for cash, shares of our common stock or a combination of cash and shares of our common stock at an initial exchange rate of approximately 42.5822 shares per one thousand dollars principal amount of Notes at the option of the Operating Partnership.

The Operating Partnership may redeem the Notes at any time to preserve the Company’s status as a REIT. In addition, on or after April 5, 2012, the Operating Partnership may redeem the Notes for cash, in whole or in part, at 100% of the principal amount plus accrued and unpaid interest, upon at least 30 days but not more than 60 days prior written notice to holders of the Notes.

The holders of the Notes have the right to require the Operating Partnership to repurchase the Notes for cash, in whole or in part, on each of April 1, 2012, April 1, 2017 and April 1, 2022, and upon the occurrence of a designated event, in each case for a repurchase price equal to 100% of the principal amount of the Notes plus accrued and unpaid interest. Certain events are considered “Events of Default,” as defined in the indenture governing the Notes, which may result in the accelerated maturity of the Notes.

The Company has considered whether the exchange settlement feature represents an embedded derivative within the debt instrument under the guidance of FASB Statement No. 133: “Accounting for Derivative Instruments and Hedging Activities” (“FAS 133”), EITF Issue 90-19: “Convertible Bonds with Issuer Option to Settle for Cash Upon Conversion,” and EITF

15

Issue No. 01-6: “The Meaning of “Indexed to a Company’s Own Stock”“ that would require bifurcation (i.e. separate accounting of the note and the exchange settlement feature).  The Company has concluded that the exchange settlement feature has satisfied the exemption in FAS 133 because it is indexed to the Company’s own common stock and would otherwise be classified in stockholders’ equity, among other considerations.  Accordingly, the Notes are presented as a single debt instrument (often referred to as “Instrument C” in EITF 90-19) in accordance with APB 14: “Accounting for Convertible Debt and Debt Issued with Stock Purchase Warrants,” due to the inseparability of the debt and the exchange settlement.

11.       LINE OF CREDIT

On October 19, 2007, the Operating Partnership entered into a new $100,000 revolving line of credit (the “Credit Line”) that matures October 31, 2010.  The Company intends to use the proceeds of the Credit Line for general corporate purposes.  The Credit Line has an interest rate of between 100 and 205 basis points over LIBOR, depending on certain financial ratios of the Company.  The Credit Line is collateralized by mortgages on certain real estate assets.  As of March 31, 2008, the Credit Line had $100,000 of capacity based on the assets collateralizing the Credit Line.  No amounts were outstanding on the Credit Line at March 31, 2008 or December 31, 2007.  The Company is subject to certain restrictive covenants relating to the Credit Line.  The Company was in compliance with all covenants as of March 31, 2008.

12.       OTHER LIABILTIES

The components of other liabilities are summarized as follows:

13.       RELATED PARTY AND AFFILIATED REAL ESTATE JOINT VENTURE TRANSACTIONS

14.       MINORITY INTEREST REPRESENTED BY PREFERRED OPERATING PARTNERSHIP UNITS

On June 15, 2007, the Operating Partnership entered into a Contribution Agreement with various limited partnerships affiliated with AAAAA Rent-A-Space to acquire ten self-storage facilities (the “Properties”) in exchange for the issuance of newly designated Preferred OP units of the Operating Partnership. The self-storage facilities are located in California and Hawaii.

On June 25 and 26, 2007, nine of the ten properties were contributed to the Operating Partnership in exchange for consideration totaling $137,800. Preferred OP units totaling 909,075, with a value of $121,700, were issued along with the assumption of approximately $14,200 of third-party debt, of which $11,400 was paid off at close. The final property was contributed on August 1, 2007 in exchange for consideration totaling $14,700. 80,905 Preferred OP units with a value of $9,800 were issued along with $4,900 of cash.

On June 25, 2007, the Operating Partnership loaned the holders of the Preferred OP units $100,000. The note receivable bears interest at 4.85%, and is due September 1, 2017. The loan is secured by the borrower’s Preferred OP units. The holders of the Preferred OP units can convert up to 114.5 million Preferred OP units prior to the maturity date of the loan. If any redemption in excess of 114.5 million Preferred OP units occurs prior to the maturity date, the holder of the Preferred OP units is required to repay the loan as of the date of that Preferred OP unit redemption. Preferred OP units are shown on the balance sheet net of the $100,000 loan under the guidance in EITF No. 85-1, “Classifying Notes Receivable for Capital,” because the borrower under the loan receivable is also the holder of the Preferred OP units.

The Operating Partnership entered into a Second Amended and Restated Agreement of Limited Partnership (the “Partnership Agreement”) which provides for the designation and issuance of the Preferred OP units. The Preferred OP units will have priority over all other partnership interests of the Operating Partnership with respect to distributions and liquidation.

Under the Partnership Agreement, Preferred OP units in the amount of $115,000 bear a fixed priority return of 5% and have a fixed liquidation value of $115,000. The remaining balance will participate in distributions with and have a liquidation value equal to that of the common OP units. The Preferred OP units will be redeemable at the option of the holder on or after September 1, 2008, which redemption obligation may be satisfied, at the Company’s option, in cash or shares of its common stock.

At issuance, in accordance with SFAS 133: “Accounting for Derivative Instruments and Hedging Activities”, SFAS 150: “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity”,  EITF 00-19: “Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock”,  EITF Topic D-109: “Determining the Nature of a Host Contract Related to a Hybrid Financial Instrument Issued in the Form of a Share under FASB Statement No. 133”: and Accounting Series Release  (“ASR”) No. 268: “Presentation in Financial Statements of “Redeemable Preferred Stocks,” from inception through September 28, 2007 (the date of the amendment discussed below), the Preferred OP units were classified as a hybrid instrument such that the value of the units associated with the fixed return were classified in mezzanine after total liabilities on the balance sheet and before stockholders’ equity. The remaining balance that participates in distributions equal to that of common OP units had been identified as an embedded derivative and had been classified as a liability on the balance sheet and recorded at fair value on a quarterly basis with any

17

adjustment being recorded through earnings. For the year ended December 31, 2007, the fair value adjustment associated with the embedded derivative was $1,054.

On September 28, 2007, the Operating Partnership entered into an amendment to the Contribution Agreement (the “Amendment”). Pursuant to the Amendment, the maximum number of shares that can be issued upon redemption of the Preferred OP units was set at 116 million, after which the Company will have no further obligations with respect to the redeemed or any other remaining Preferred OP units. As a result of the Amendment, and in accordance with the above referenced guidance, the Preferred OP units are no longer considered a hybrid instrument and the previously identified embedded derivative no longer requires bifurcation and is considered permanent equity of the Operating Partnership.  The Preferred OP units are included on the consolidated balance sheet as the minority interest represented by Preferred OP units, and no recurring fair value measurements are required subsequent to the date of the Amendment.

15.       MINORITY INTEREST IN OPERATING PARTNERSHIP

The Company’s interest in its properties is held through the Operating Partnership. ESS Holding Business Trust I, a wholly owned subsidiary of the Company, is the sole general partner of the Operating Partnership. The Company, through ESS Holding Business Trust II, a wholly owned subsidiary of the Company, is also a limited partner of the Operating Partnership. Between its general partner and limited partner interests, the Company held a 92.92% majority ownership interest therein as of March 31, 2008. The remaining ownership interests in the Operating Partnership (including Preferred OP units) of 7.08% are held by certain former owners of assets acquired by the Operating Partnership, which include a director and officers of the Company.

The minority interest in the Operating Partnership represents OP units that are not owned by the Company. In conjunction with the formation of the Company and as a result of subsequent acquisitions, certain persons and entities contributing interests in properties to the Operating Partnership received limited partnership units in the form of either OP units or CCUs. Limited partners who received OP units in the formation transactions or in exchange for contributions for interests in properties have the right to require the Operating Partnership to redeem part or all of their OP units for cash based upon the fair market value of an equivalent number of shares of the Company’s common stock (10 day average) at the time of the redemption. Alternatively, the Company may, at its option, elect to acquire those OP units in exchange for shares of its common stock on a one-for-one basis, subject to anti-dilution adjustments provided in the Partnership Agreement. The ten day average closing stock price at March 31, 2008 was $16.51 and there were 4,072,857 OP units outstanding. Assuming that all of the unit holders exercised their right to redeem all of their OP units on March 31, 2008 and the Company elected to pay the non-controlling members cash, the Company would have paid $67,243 in cash consideration to redeem the OP units.

As of March 31, 2008, the Operating Partnership had 4,072,857 and 107,163 OP units and CCUs outstanding, respectively.

Unlike the OP units, CCUs do not carry any voting rights. Upon the achievement of certain performance thresholds relating to 14 properties, all or a portion of the CCUs will be automatically converted into OP units. Initially, each CCU will be convertible on a one-for-one basis into OP units, subject to customary anti-dilution adjustments. Beginning with the quarter ended March 31, 2006, and ending with the quarter ending December 31, 2008, the Company will calculate the net operating income from the 14 wholly-owned properties over the 12-month period ending in such quarter. Within 35 days following the end of each quarter referred to above, some or all of the CCUs will be converted so that the total percentage (not to exceed 100%) of CCUs issued in connection with the formation transactions that have been converted to OP units will be equal to the percentage determined by dividing the net operating income for such period in excess of $5,100 by $4,600. If any CCU remains unconverted through the calculation made in respect of the 12-month period ending December 31, 2008, such outstanding CCUs will be cancelled.

While any CCUs remain outstanding, a majority of the Company’s independent directors must review and approve the net operating income calculation for each measurement period and also must approve any sales of any of the 14 wholly-owned properties.

As of March 31, 2008, there were 92,883 CCUs converted to OP units.  Based on the performance of the properties as of March 31, 2008, an additional 17,915 CCUs became eligible for conversion.  The board of directors approved the conversion of these CCUs on May 1, 2008 as per the Company’s charter, and the OP units were issued on May 5, 2008.

16.  STOCKHOLDERS’ EQUITY

The Company’s charter provides that it can issue up to 300,000,000 shares of common stock, $0.01 par value per share, 4,100,000 CCSs, $.01 par value per share, and 50,000,000 shares of preferred stock, $0.01 par value per share. As of March 31, 2008, 66,437,222 shares of common stock were issued and outstanding, 2,083,232 CCSs were issued and outstanding and no shares of preferred stock were issued and outstanding. All holders of the Company’s common stock are entitled to receive dividends and to one vote on all matters submitted to a vote of stockholders.

Unlike the Company’s shares of common stock, CCSs do not carry any voting rights. Upon the achievement of certain performance thresholds relating to 14 properties, all or a portion of the CCSs will be automatically converted into shares of the Company’s common stock. Initially, each CCS will be convertible on a one-for-one basis into shares of common stock, subject to customary anti-dilution adjustments. Beginning with the quarter ended March 31, 2006, and ending with the quarter ending December 31, 2008, the Company will calculate the net operating income from the 14 wholly-owned properties over the 12-month period ending in such quarter. Within 35 days following the end of each quarter referred to above, some or all of the CCSs will be converted so that the total percentage (not to exceed 100%) of CCSs issued in connection with the formation transactions that have been converted to common stock will be equal to the percentage determined by dividing the net operating income for such period in excess of $5,100 by $4,600. If any CCS remains unconverted through the calculation made in respect of the 12-month period ending December 31, 2008, such outstanding CCSs will be cancelled and restored to the status of authorized but unissued shares of common stock.

While any CCSs remain outstanding, a majority of the Company’s independent directors must review and approve the net operating income calculation for each measurement period and also must approve any sales of any of the 14 wholly-owned properties.

As of March 31, 2008, there were 1,805,611 CCSs converted to common stock.  Based on the performance of the properties as of March 31, 2008, an additional 348,274 CCSs became eligible for conversion.  The board of directors approved the conversion of these CCSs on May 1, 2008 as per the Company’s charter, and the shares were issued on May 5, 2008.

17.  STOCK-BASED COMPENSATION

The Company has the following two stock option plans under which shares were available for grant at March 31, 2008: 1) the 2004 Long-Term Incentive Compensation Plan, and 2) the 2004 Non-Employee Directors’ Share Plan (together, the “Plans”).  Option grants are issued at the closing price of stock on the date of grant.  Each option will be exercisable after the period or periods specified in the award agreement (typically four years), which will generally not exceed 10 years from the date of grant. Options are exercisable at such times and subject to such terms as determined by the Compensation, Nominating and Governance Committee, but under no circumstances may be exercised if such exercise would cause a violation of the ownership limit in the Company’s charter.  Unless otherwise determined by the Compensation, Nominating and Governance Committee at the time of grant, options shall vest ratably over a four-year period beginning on the date of grant.

Also as defined under the terms of the Plans, restricted stock grants may be awarded.  The stock grants are subject to a performance or vesting period over which the restrictions are lifted and the stock certificates are given to the grantee.  During the performance or vesting period, the grantee is not permitted to sell, transfer, pledge, encumber or assign shares of restricted stock granted under the Plans, however the grantee has the ability to vote the shares and receive dividends paid on the shares.  The forfeiture and transfer restrictions on the shares lapse over a two to four-year period beginning on the date of grant.

Option Grants to Employees

As of March 31, 2008, 5,023,743 shares were available for issuance under the Plans.  A summary of stock option activity is as follows:

The aggregate intrinsic value in the table above represents the total value (the difference between the Company’s closing stock price on the last trading day of the first quarter of 2008 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on March 31, 2008. The amount of aggregate intrinsic value will change based on the fair market value of the Company’s stock.

The fair value of each option grant is estimated using the Black-Scholes option-pricing model with the following assumptions:
