NASDAQ OMX Group (NDAQ)

Report of Independent Auditor

To the Shareholders in OMX AB

We have audited the accompanying consolidated balance sheets of OMX AB and its subsidiaries as of December 31, 2007 and December 31, 2006 and the related consolidated statements of income, shareholders’ equity and cash flows for the years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of OMX AB and its subsidiaries at December 31 2007 and December 31, 2006 and the results of their operations and their cash flows for each of the years then ended in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.
