LETTER FROM THE BOARD

Dear Shareholders and Business Partners, Ladies and Gentlemen

Two years ago, in mid-summer 2008, we informed you about the start of what we called the "first step towards the implementation of alstria's future capital structure". We have now finished this programme and alstria has been able to completely refinance its EUR 1.1 billion credit facility. The most important step in that process was the replacement of the remaining EUR 646 million loan with a credit facility from a new banking syndicate on July 20, 2010. A consortium of five banks has provided a new syndicated five-year loan of EUR 630 million, increasing the average maturity of our liabilities significantly from 2.4 years to 5.1 years. The Company now has no further refinancing needs until mid-2014. The combination of the long-term secured financing with the strength of our rental income provides stable cash flows and unique visibility over the next five years.

We have also continued our strategy of selective sales of property, taking advantage of the increased demand for long-term leased property. In July 2010, alstria agreed to sell another four properties in Hamburg for a total amount of EUR 81.7 million. The sales have been agreed at an average premium of 5% over the appraised values as at December 31, 2009.

These sales not only allow alstria to generate additional profit, but they will also significantly improve alstria's G-REIT equity ratio. Although it is too early to call it a day, these sales clearly put us in an ideal position to meet our target of restoring the required 45% equity ratio by the end of 2010.

With the successful refinancing of its syndicated loan, and by taking advantage of the strong demand for longterm leased assets, alstria has almost concluded its step by step approach to strengthen its balance sheet. Over the past 24 months, the company has been successful in managing the severe challenges posed by the financial and economic crisis without having to take any steps that dilute the Company's capital.

alstria finds itself with a comfortable liquidity position, and has managed to overcome any financing concerns for the next four years. We are now sailing with one of the longest lease maturities and the highest debt maturity profile in Continental Europe. We believe that the real estate industry will be facing strong headwinds linked to significant refinancing needs over the next two to three years. We will continue to focus on increasing the value of our existing portfolio with continuing investments in our refurbishment assets, and continue monitoring the investment market for any investment opportunities that may arise as financing issues unfold.

With kind regards,

Olivier Elamine Chief Executive Officer (CEO)

Alexander Dexne Chief Financial Officer (CFO)

ALSTRIA STOCK

SHARE PRICE DEVELOPMENT

Stock markets continued to be highly volatile in the course of the first half year 2010. Investor sentiment fluctuated with conflicting good corporate news, concerns about public budgets and uncertainty about future economic developments. The alstria share could not escape these trends, but it still outperformed the major indices EPRA Germany and EPRA Europe.

alstria's share price rose from EUR 7.50 on December 31, 2009 to EUR 7.80 on June 30, 2010, and fluctuated between EUR 6.92 and EUR 8.78 during this period. The share price movements also reflect the dividend payment on June 17, 2010, which resulted in a corresponding markdown of the share price.

Following the end of the half-year, the alstria share price benefited from the current upward trend of real estate shares, closing at EUR 8.90 on August 10, 2010.

The Annual General Meeting of alstria office REIT-AG held on June 16, 2010 resolved to grant a dividend entitlement of EUR 0.50 per share for the financial year 2009. This represents a total dividend payment of EUR 27,999 k, which is fully covered by the company's operative cash flow.

INTERIM MANAGEMENT REPORT

PORTFOLIO OVERVIEW

As at June 30, 2010, the alstria Group managed a portfolio of 74 buildings with approximately 820,300 sqm of lettable area and a contractual vacancy rate of 7.7%. The portfolio yield is 6.2% and the weighted remaining average lease term is approximately 9.2 years. alstria also holds a 49% share in two joint ventures, each consisting of one Hamburg real estate asset.

For a detailed description of the alstria portfolio, please refer to the Annual Report 2009.

Transactions

In January 2010, alstria agreed joint venture terms with the Hamburg-based developer and fund manager Quantum Immobilien AG with respect to the renovation of the Kaisergalerie at Grosse Bleichen 23-27 in Hamburg. It is the second joint venture between Quantum and alstria as part of the overall strategy to fund organic growth opportunities.

Asset management

alstria's asset management has been successful in re-letting vacant floorspace. alstria signed lease agreements totalling around 8,300 sqm in the first half of 2010. The biggest reletting successes have been the new lease agreements within the joint venture 'Alte Post'. The office space of around 3,500 sqm has been leased for 10 years to the law firm Graf von Westphalen. Moreover, the retailer Tommy Hilfiger has taken out a long-term lease on around 800 sqm of retail space. Tommy Hilfiger is the first retail tenant of the prime Alte Post building. Renovations are proceeding on schedule and will probably be finished in the fourth quarter of 2011. We also extended a number of leases, which have had a huge impact on our lease expiry profile. alstria was able to reduce its expiry rate for 2010 and 2011 from 10.6% to 7.3%. Most of this reduction of 3.3% refers to leases that have been extended to 2016.

The Group's modernisation projects are progressing well. The refurbishment of Steinstrasse 5-7, in Hamburg had been completed and the new tenant, Hamburger Hochbahn AG, recently took occupation of around 13,000 sqm. The refurbishment of Bäckerbreitergang 73/75 in Hamburg was also completed. The property serves as alstria's new headquarters.

Looking at alstria's entire portfolio, the sale of fully-let assets, the deconsolidation of the fully-let Grosse Bleichen property and the expansion of strategic vacancies for new modernisation projects increased the vacancy rate by 1.2% to 7.7%, or 63,400 sqm. Strategic vacancies for new modernisation projects increased over the last six months from 15,800 sqm to 32,400 sqm. The remaining 31,000 sqm represents operational vacancies.

Tenants and utilisation

Our key focus on a set number of major tenants is still one of the main characteristics of our portfolio. More than 80% of total revenues are generated by our top nine tenants. The 2010 portfolio also reflects the clear focus on the office asset class. Out of our total lettable area of 820,300 sqm, around 94% is dedicated to offices.

EARNINGS POSITION

Revenues decreased due to asset disposals

Revenues decreased in the first half of 2010 by 12.5% due to asset disposals in the previous and current year. Revenues amounted to EUR 45,192 k (previous half year: EUR 51,647 k) with real estate operating expenses of around 7.0% of revenues at EUR 3,162 k (H1 2009: EUR 4,821 k or 9.3% of revenues). As a consequence of the asset disposals, net rental income decreased by EUR 4,776 k, down to EUR 42,050 k compared to the first half-year 2009.

Administrative expenses and personnel expenses amounted to EUR 5,617 k compared to EUR 5,356 k in H1 2009. Accordingly, operating expenses amounted to 12.4% of total revenues for the first half-year 2010 (H1 2009: 10.4%).

alstria was able to generate a net profit from asset sales of EUR 5,635 k. This results from the latest Hamburg portfolio transaction, which was concluded on March 31, 2010.

alstria closed the first half-year 2010 with a net operating

result of EUR 42,009 k. This compares with a net operating result of EUR 26,636 k in the first half of the previous year. The significant increase in the net operating result is linked to the one-off valuation change that the company had to recognise in Q1 2009 (EUR 8,215 k) following the increase in the property transfer tax rates.

FUNDS FROM OPERATIONS (FFO) AT EUR 0.28 PER SHARE

EUR k	Jan. 1- Jun. 30, 2010	Jan. 1- Jun. 30, 2009
Pre-tax income (EBT)	11,605	-2,286

+/– Non-cash expenses/income	567	593
Funds from operations (FFO)1	15,704	16,174

¹ FFO is not a measure of operating performance or liquidity under generally accepted accounting principles, in particular IFRS, and should not be considered as an alternative to the company's income or cash-flow measures as determined in accordance with IFRS. Furthermore, no standard definition exists for FFO. Thus, the FFO or measures with similar names as presented by other companies may not necessarily be comparable to alstria's FFO.

Funds from operations (FFO) were EUR 15,704 k for the reporting period, compared to EUR 16,174 k in the first half-year 2009. As a result, FFO per share amounted to EUR 0.28 in the first half-year 2010 (H1 2009: EUR 0.29). The reason for the decline is as expected a decrease in revenues (EUR - 6,455 k) due to asset disposals in 2009. These negative effects have been partially mitigated by a decrease in real estate operating expenses and lower financing cost.

The FFO from the first half-year still includes revenues from assets in the Hamburg portfolio that were sold in Q1 2010, and the FFO cannot therefore be used to calculate a linear projection for the full year. FFO guidance for the full year remains unchanged at EUR 27 m.

Hedging Instruments

Hedge accounting is applied to all qualifying hedging instruments in order to minimise the impact of the volatility of interest rate markets on the profit and loss account. This allows the loss or gain of a designated derivative to be recognised through the cash flow hedge reserve. (For more details, please refer to the notes to the consolidated financial statements as at December 31, 2009).

Hedging instruments as at June 30, 2010 -38,231 185 -35,761 -35,576

An increase of EUR 640 k in the first half-year 2010 was recognised in equity in the cash flow hedge reserve (H1 2009: decrease of EUR 16,155 k in the cash flow hedge reserve). The impact on revenues of changes in fair value of derivatives of EUR – 4,837 k is reflected in the income statement. The changes in interest accruals on swaps and caps (EUR 1,520 k) are recognised in the financial result. A loss of EUR 4,329 k relates to the cumulated losses from a cash flow hedge for which the forecast hedged transaction is no longer expected to occur due to redemption of a loan before maturity. This results in a total loss of EUR -9,167 k (H1 2009: EUR -2,735 k), which is recognised under net loss from valuation of financial derivatives at fair value. Swaps with a notional value of EUR 256,863 k were terminated in the first half-year. This reduced financial liabilities from the negative fair value of these swaps by EUR 15,345 k. This equals the cash outflow for the termination of the swaps and has no effect on net income.

The new swap with a notional value of EUR 37,283 k was concluded with a zero fair value at inception of the hedging transaction.

Financial result

THE FOLLOWING TABLE SHOWS THE FINANCIAL RESULT FOR THE PERIOD JANUARY 1 TO JUNE 30, 2010:

EUR k	Jan. 1- Jun. 30, 2010	Jan. 1- Jun. 30, 2009	Change
Syndicated loan - interest and similar costs	-6,405	-16,443	-61.0%
Interest loan refinanced	-3,736	-1,682	122.1%
Interest result derivatives	-11,188	-7,927	41.1%
Other interest expenses	-1	-1	0,0%
Financial expenses	-21,330	-26,052	-18.1%
Financial income	304	526	-42.2%
Other financial expenses	-305	-661	-53.8%
Net financing costs	-21,331	-26,187	-18.5%

Net financing costs decreased by EUR 4,856 k to EUR 21,331 k in comparison with H1 2009. The decrease is partly attributable to a lower average loan level compared to the previous reporting period, which results from the extensive refinancing activities carried out in 2009 and 2010. On the other hand, terminations of derivatives with comparably high swap rates led to a decrease of average interest costs.

Consolidated net result driven by asset sales

The consolidated net result amounts to EUR 11,605 k (H1 2009: loss of EUR -2,286 k). The increase in the consolidated net result is mainly based on the profit from asset disposals of EUR 5,635 k and lower fair value adjustments on investment properties and financial derivatives (H1 2010: EUR 9,167 k as against EUR 17,867 k in H1 2009).

Earnings per share are EUR 0.21 for the first six months of 2010.

FINANCIAL AND ASSET POSITION

Financial management

Financial management of the alstria-Group is carried out at a centralised corporate level, with individual loans being taken out at property and portfolio level. The main aim of the Group's financial policy is the establishment of secured, long-term financial structures to support the development of its business and to provide the required degree of flexibility. The corporate management of alstria's debt financing forms the basis for harmonised capital procurement, optimised management of interest and liquidity risks and efficiency improvements for the whole Group.

In January 2010, alstria entered into a new credit facility on a non-recourse basis against alstria office REIT-AG as an additional step towards decreasing the syndicated loan facility that runs out at the end of 2011. The credit facility is a 7-year non-recourse loan of EUR 76 million at a fixed interest rate of 4.62%. The refinanced assets are located in Hamburg, Essen and Leipzig.

In January 2010, alstria also made a voluntary repayment of capital of EUR 20 million against its main syndicated loan facility in order to meet the declared target of the Group to keep the LTV ratio of its main syndicated facility below 60% on the relevant reporting date in January 2010. This voluntary repayment secures the margin of 85 bps for the next two interest periods.

After the closing of the above mentioned asset sales concluded in Q4 2009, and respective debt repayment, the remaining main syndicated loan facility exposure was reduced to EUR 646 million, which is in line with the Group's target.

alstria complied with all financial covenants as at June 30, 2010.

Cash position is EUR 64,548 k

Cash flow from operating activities for the first six months of the year amounted to EUR 13,364 k, representing a slight decrease compared to the first half-year 2009 (EUR 14,789 k). This is mainly based on lower rental revenues due to the disposal of assets.

The cash flow from investing activities comprises cash inflow resulting from the sale of real estate (EUR 82,528 k). A cash outflow of EUR 9,444 k refers to payments for refurbishment measures for re-letting, and subsequent acquisition costs.

The cash flow from financing activities reflects loan repayments of EUR 245,174 k and payments for the termination of financial derivatives amounting to EUR 15,345 k. Cash inflows of EUR 108,629 k refer to loans taken out during refinancing and EUR 13,546 k from repayment of loans granted.

As a result, alstria ended the first half-year 2010 with a cash position of EUR 64,568 k (June 30, 2010: EUR 61,683 k).

Investment properties stable at end of the quarter

The total value of investment property amounts to EUR 1,356,984 k at the reporting date as compared to EUR 1,425,440 k at the beginning of the financial year. Four investment properties destined to be sold have been reclassified as "investments held for sale". Further changes to investments held for sale result from capitalised refurbishment costs relating to the development project at Steinstrasse 5-7 in Hamburg. Interests in real estate joint ventures refer to the at-equity consolidation method used for the Hamburg assets in Grosse Bleichen and the Alte Post.

Equity ratio of 40.4% – G-REIT equity ratio1 at 42.5%

The balance sheet reflects a total equity position of EUR 622,933 k with an equity ratio of 40.4% (December 31, 2009: EUR 634,185 k or 35.9%). The G-REIT equity ratio increased by 2.2 percentage points to 42.5% (December 31, 2009: 40.3%). This development supports our belief that alstria will comply with the required G-REIT equity ratio of 45% by the end of the financial year.

NNNAV at EUR 11.12 per share

NNNAV (Triple Net Asset Value according to EPRA2 ) decreased from EUR 11.32 per share to EUR 11.12 per share. The consolidated profit for the period (EUR 11,605 k) and the 2009 dividend (EUR 27,999 k) are primarily responsible for the changes to equity. This leads to a total decrease in equity from EUR 634,185 k to EUR 622,933 k3 .

Further decrease of financial debt

Our latest transactions have allowed us to further reduce non-current loans by 8.8% to EUR 863,754 k. This is mainly related to selective asset disposals, the new joint venture and voluntary prepayments of capital.

The G-REIT equity ratio is defined as the ratio of equity to immovable assets

EPRA: European Public Real Estate Association, Best Practices Committee, Schiphol Airport, The Netherlands.

Please also refer to the Statement of changes in equity prior to the Notes, Page 16

Decrease in current liabilities

Current liabilities decreased by 83.1% to EUR 22,589 k, which is mainly due to the repayment of EUR 91,941 k categorised as current loans as at December 31, 2009. Other current liabilities amounting to EUR 6,672 k mainly comprise deferred income, accruals for outstanding invoices, accrued bonuses and received deposits.

RISK AND OPPORTUNITY REPORT

The risks and opportunities to which alstria is exposed are described in detail in the Annual Report 2009. There have been no changes to the status described in that report.

RECENT DEVELOPMENTS AND OUTLOOK

Refinancing strategy completed

alstria successfully refinanced its main credit facility on July 20, 2010. A new syndicate consisting of five banks has provided a new credit facility totalling EUR 630 million. Together with EUR 16 million of alstria's own cash, this refinancing entirely replaced the previous syndicated loan facility (EUR 646 million), which was due to mature in November 2011. The new loan agreement has a maturity of five years. This significantly increases our debt maturity profile from 2.4 years to 5.1 years. The new loan was arranged by UniCredit Bank AG and underwritten by Berlin-Hannoversche Hypothekenbank AG, Eurohypo Aktiengesellschaft, HSH Nordbank AG, and Natixis.

The initial margin on the new loan will be 160 bps and essentially depends on the Loan-To-Value ratio (LTV) according to the following margin grid. The current LTV for the new loan agreement is 58.4%.

MARGIN GRID

LTV					Spread
65%	<	LTV	≤	70%	200 bp per annum
61%	<	LTV	≤	65%	175 bp per annum
56%	<	LTV	≤	61%	160 bp per annum
51%	≤	LTV	≤	56%	150 bp per annum

During refinancing, alstria restructured its existing hedging instruments according to the new debt maturity profile. Around 25% of the new loan is held without interest rate hedging instruments in order to increase the operational flexibility of the company. Under the new structure, our total financing costs remain stable at around 4.3%. Taking our long-term lease profile into account, the new credit facility significantly improves the visibility of our cash flow for the next five years. With the new syndicated loan in place, alstria has no further refinancing needs before mid-2014.

In line with its hedging strategy, during refinancing alstria entered into a new interest rate swap for a notional amount of EUR 472,500 k and an interest rate of 2.99%. This interest rate swap expires on July 20, 2015 and became effective on July 20, 2010. It replaces the existing interest swap with a notional amount of EUR 625,000 k, which has been terminated with effective date July 20, 2010.

Office property disposal

In July 2010, alstria concluded binding and notarised sale agreements for the disposal of two properties in Hamburg. The assets were sold at a premium to the year-end valuation and IFRS-results as of June 30, 2010. The transfer of possession, benefits and burden is expected to take place in the third quarter of 2010.

Financial guidance

alstria confirms anticipated revenues of ca. EUR 89 m and anticipated funds from operations (FFO) of EUR 27 m for the year 2010.

The gain on property disposal totalled TEUR 5,635 k for the first half-year 2010.

Four properties have been categorised pursuant to IFRS 5 as "assets held for sale" in the consolidated financial statements as of June 30, 2010. For further information, please refer to section 15 of these Notes.

For a detailed description of the loans, loan terms and loan securities, please refer to section 11.2 of the consolidated financial statements as at December 31, 2009.

9. Dividends

EUR k	June 30, 2010 (unaudited)	June 30, 2009 (unaudited)
Dividend1 per share for 2009: EUR 0.50 (2008: EUR 0.52)	27,999	28,423

1 Refers to all shares except treasury shares at the end of the reporting period

The Annual General Meeting of alstria office REIT-AG held on June 16, 2010 resolved to distribute dividends totalling EUR 27,999 (EUR 0.50 per ordinary share). The dividend was distributed on June 17, 2010.

10. Employees

In the period from January 1, 2010 to June 30, 2010, an average of 35 people (January 1, 2009 to June 30, 2009: average 31 people) were employed by the Company. The average number of employees was calculated by the total of employees at the end of each month. On June 30, 2010, 37 people (December 31, 2009: 32 people) were employed at alstria office REIT-AG, excluding the management board.

11. Share-based payment

On March 2, 2010, the Company's supervisory board resolved to establish a new share-based remuneration system, the Long Term Incentive Plan (LTIP), for members of the management board and granted a first tranche of virtual shares to the management board.

Under the LTIP, alstria office REIT-AG grants virtual shares giving entitlement to convert into cash payments after four years.

The amount of the conversion payment is based on the number of virtual shares, multiplied by the average stock market price of alstria's shares on the Frankfurt Stock Exchange during the last 60 trading days prior to the relevant maturity date, plus an amount equal to the sum of the dividend per share paid by the company to its shareholders between the grant date and the maturity date, but in no event higher than 250% of the average stock market price of alstria'a shares on the Frankfurt Stock Exchange of the last 60 trading days prior to the relevant grant date, multiplied by a specified discretionary factor.

The discretionary factor shall be a multiplier that may vary between 0.8 and 1.2, and is subject to the individual performance of each participant during the respective holding period.

The determination of virtual shares that vest will depend in equal amounts on the achievement of the alstria share price (absolute total shareholder return) and on the relative performance of the alstria share in relation to the EPRA REIT Index Continental Europe (relative total shareholder return).

Since payment per vested virtual share depends on the quoted price of the alstria share, the quoted price at the end of the reporting period mainly represents the fair value of each virtual share.

At the end of the reporting period there were 99,009 virtual shares that were granted on March 2, 2010.

In the first half-year 2010, these generated remuneration expenses amounting to EUR 78 k, which equals the provision set aside for virtual shares. The Group recognizes the liabilities arising from the vested virtual shares under other provisions.

12. Convertible Profit Participation Rights Program

Under the convertible profit participation rights scheme established by the supervisory boardof alstria office REIT-AG on September 5, 2007, 61,500 convertible profit participation certificates ("certificates") had been issued to the employees of alstria office REIT-AG with the granting date of June 17, 2010. The nominal amount of each certificate is EUR 1.00 and is payable on issuance. The fair value of the inherent options for conversion is estimated using a binary barrier option model based on the black-scholes pricing model. The model takes into account the terms and conditions upon which the instruments were granted. For a detailed description of the convertible profit participation rights program, please refer to section 18 of the consolidated financial statements as of December 31, 2009.

The following table shows the inputs to the model used for the determination of the options for conversion granted on June 17, 2010:

	June 30, 2010 (unaudited)
Dividend yield (%)	6.06
Risk-free interest rate (%)	0.47
Expected volatility (%)	58.00
Expected life option (years)	2.00
Exercise share price (EUR)	2.00
Employee fluctuation rate (%)	10.00
Stock price as of valuation date (EUR)	8.25

The fair value of one option for conversion at the granting date was EUR 6.19.

13. Related Parties

Except for the granting of virtual shares to the members of the Company's management board as detailed in note 11, no legal significant transactions with related parties took place during the reporting period.

Due to a joint venture agreement concluded in the first halfyear 2010, a former Group subsidiary is treated as a joint venture as at reporting date for the interim financial statements. It has been treated as related party since the deconsolidation.

14. Financial Commitments

The financial commitments arising out of a general contractor agreement entered into by alstria in 2009 and disclosed in Note 12.2 of the annual financial statements for 2009 have now been settled.

15. Significant Events After the End of the Reporting Period

In line with our hedging strategy, we entered into a new interest rate swap with a notional amount of EUR 472,500 k and a swap rate of 2.99%, expiring on July 20, 2015. This transaction became effective as per July 20, 2010.

The aforementioned swap replaced the existing interest swap with EUR 625,000 k notional amount terminated with effective the date July 20, 2010.

On July 20, 2010, the Company refinanced its main credit facility (EUR 646 million) using EUR 630 million from a new loan agreement and EUR 16 million from available cash. The new loan agreement has a maturity of five years.

In July 2010 alstria concluded binding and notarised sale agreements for the sale of four properties in Hamburg. The transfer of possession, benefits and burden is expected to take place in the third quarter of 2010.

We have reviewed the condensed consolidated interim financial statements - comprising the condensed statement of financial position, condensed statement of comprehensive income, condensed cash flow statement, condensed statement of changes in equity and selected explanatory notes - and the interim group management report of alstria office REIT-AG, Hamburg, for the period from January 1 to June 30, 2010, which are part of the half-year financial report pursuant to § (Article) 37w WpHG ("Wertpapierhandelsgesetz": German Securities Trading Act). The preparation of the condensed consolidated interim financial statements in accordance with the IFRS applicable to interim financial reporting as adopted by the EU and of the interim group management report in accordance with the provisions of the German Securities Trading Act applicable to interim group management reports is the responsibility of the parent Company's Board of Managing Directors. Our responsibility is to issue a review report on the condensed consolidated interim financial statements and on the interim group management report based on our review.

We conducted our review of the condensed consolidated interim financial statements and the interim group management report in accordance with German generally accepted standards for the review of financial statements promulgated by the Institut der Wirtschaftsprüfer (Institute of Public Auditors in Germany) (IDW). Those standards require that we plan and perform the re-view so that we can preclude through critical evaluation, with moderate assurance, that the condensed consolidated interim financial statements have not been prepared, in all material respects, in accordance with the IFRS applicable to interim financial reporting as adopted by the EU and that the interim group management report has not been prepared, in all material re-spects, in accordance with the provisions of the German Securities Trading Act applicable to interim group management reports. A review is limited primarily to inquiries of company person-nel and analytical procedures and therefore does not provide the assurance attainable in a financial statement audit. Since, in accordance with our engagement, we have not performed a financial statement audit, we cannot express an audit opinion.

Based on our review, no matters have come to our attention that cause us to presume that the condensed consolidated interim financial statements have not been prepared, in all material respects, in accordance with the IFRS applicable to interim financial reporting as adopted by the EU nor that the interim group management report has not been prepared, in all material respects, in accordance with the provisions of the German Securities Trading Act applicable to interim group management reports.
