Dear Unitholder

Charter Hall Office Management Limited ABN 75 006 765 206 AFS Licence No. 247075 Responsible entity of Charter Hall Office REIT Level 11, 333 George Street Sydney NSW 2000 GPO Box 2704 Sydney NSW 2001 Direct +61 2 8908 4000 Australia 1300 365 585 International +61 2 8908 4036 Registry 1300 303 063 Fax +61 2 8908 4040 charterhall.com.au/Charter-Hall-Office-Trust

Further to my letter accompanying the Charter Hall Office REIT (CQO) Explanatory Memorandum dated 10 February 2012, I am pleased to confirm that CQO unitholders approved the proposal for the acquisition by Reco Ambrosia Pte Ltd (an affiliate of Government of Singapore Investment Corporation Pte Ltd), the Canadian Public Sector Pension Investment Board and a member of the Charter Hall Group (ASX:CHC) (together, the Bidders) of all the issued units in CQO (except certain of those held by the Bidders or their associates) (CQO Units) by way of a trust scheme (Proposal) at the meeting of CQO unitholders held on 15 March 2012.

All conditions precedent to the Proposal have now been met, including the completion of the sale of CQO’s remaining US properties. The Proposal became effective on 13 April 2012 (Effective Date) and CQO units were suspended from trading on the Australian Securities Exchange as at close of business that day.

As you held CQO Units at 7:00pm on 20 April 2012 (Record Date), you are entitled to receive the Scheme Cash Consideration, Implementation Distributions and the Second US Sales Distribution. This letter is sent to you on the Implementation Date, being 30 April 2012, and as such these payments will be made on this date (or as soon as reasonably practicable thereafter).

A summary of all payments, including those being made on 30 April 2012 or soon thereafter, and the estimated amount of Scheme Contingent Consideration to be paid to CQO unitholders from 30 October 2012, are set out below.

Type of payments	Amount (A$ per unit) Estimated date of despatch
Scheme Cash Consideration Implementation Distributions Scheme Cash Consideration + Implementation Distributions First US Sales Distribution Second US Sales Distribution Scheme Contingent Consideration1 US Sales Distributions + Scheme Contingent Consideration Total proceeds to CQO Unitholders	$1.8332 30 April 2012 $0.6568 30 April 2012 $2.49 $0.48 8 March 2012 $0.60 30 April 2012 Estimated at $0.09 From 30 October 2012 $1.17 $3.66

==> picture [163 x 58] intentionally omitted <==

We were pleased to announce to the market on 20 April that the US Sales Proceeds total was A$1.17 per CQO unit, 5% above the A$1.11 forecast in the Explanatory Memorandum. This improvement was driven by factors including management’s ability to minimise transaction costs, structure a share of profit from the sale of one of the US properties to a third party, and more favourable AUD/USD exchange rates. Following these improvements, the total proceeds to unitholders equals CQO’s Net Tangible Assets per unit of $3.66 as at 31 December 2011.

As outlined in the Explanatory Memorandum, up to $0.15 per CQO Unit was estimated to be withheld in CQO to meet certain types of potential and contingent liabilities and costs, predominantly related to CQO’s offshore subsidiaries. As announced on the Record Date, a lower amount of approximately $0.09 per CQO Unit has been withheld, with the remaining $0.06 per CQO Unit being paid as part of the Second US Sales Distribution today. As highlighted in the table above, any amounts withheld not required to meet actual liabilities and costs will be paid to CQO unitholders as Scheme Contingent Consideration. The earliest expected date on which any Scheme Contingent Consideration will be dispatched is 30 October 2012[1] . Additional information about any amounts of Scheme Contingent Consideration will be made available on CQO’s website www.charterhall.com.au/Charter-Hall-Office-Trust from time to time.

CQO will be de-listed from the Australian Securities Exchange with effect from the close of business on 1 May 2012 or shortly thereafter. However, unitholders can continue to update their information for payment of the Scheme Contingent Consideration through Link Market Services.

A Payment Advice for those payments made on 30 April or shortly thereafter is enclosed. To assist in finalising your 2012 income tax return, an annual taxation statement will also be mailed to all unitholders following the end of the 2012 financial year.

I would like to take this opportunity to say that it has been an honour chairing the Board of Directors of CQO, and on behalf of the CHOML Board and CQO’s management, I thank all our unitholders for their support for CQO over the past 18 years as a listed fund.

Finally, enclosed for your consideration is some information on Charter Hall’s unlisted investment opportunities. Charter Hall has a 20 year track record of managing unlisted property funds and syndicates on behalf of retail investors and Charter Hall Direct Property provides opportunities for investment across all commercial property sectors.

Should you wish to discuss any of the matters raised in this letter please speak with your financial adviser or contact our investor information line on 1300 303 063 (or if calling from overseas +61 2 8280 7134).

Yours sincerely
