                    Joint Press Release, 25 May, 2007

                             Part I - Summary

The boards of directors of The NASDAQ Stock Market, Inc. ("NASDAQ") and OMX AB (publ) ("OMX") jointly announce that they have entered into an agreement (the "Transaction Agreement") to combine the two companies (the "Combination" or the "Transaction"), creating the world's premier exchange and technology company. The Combination will create the largest global network of exchanges and exchange customers linked by technology. The Combination will provide significant benefits for customers, shareholders and other stakeholders in both companies.

The new group, to be called The NASDAQ OMX Group (the "Combined Group"), brings together two companies with a common culture and vision of innovation, competitiveness and pioneering technological expertise. NASDAQ OMX Group combines two highly complementary businesses, uniting NASDAQ's leading global brand, highly efficient electronic trading platform and track record of customer focused innovation with OMX's global technology services platform and customer base, efficient Nordic Exchange, derivatives capabilities and track record of successful cross-border exchange integrations.

The Combination will be effected through a cash and stock tender offer (the "Offer") by NASDAQ for all outstanding shares in OMX. The consideration offered is equivalent to 0.502 new NASDAQ shares plus SEK94.3 in cash for each OMX share. Based on NASDAQ's closing price on 23 May, 2007, the Offer values OMX at SEK208.1 per share(1), equivalent to SEK25.1 billion ($3.7 billion) and represents a premium of 19 percent to the closing price of SEK174.5 per OMX share on 23 May, 2007, the last full trading day prior to the announcement of the Offer and a premium of 25 percent to the volume weighted average price of SEK165.9 per OMX share over the 20 trading days up to and including 23 May, 2007.

Robert Greifeld, Chief Executive Officer of NASDAQ, commented:

"The future of exchanges is about technology, flexibility and scale. NASDAQ and OMX together deliver all of these benefits. Our technology leadership and track record in linking trading platforms means we will offer issuers and investors unique benefits which were not available in one company until now. This combination provides our organizations with the ability to grow and accelerate the global flow of equity capital. At the same time, it provides us with an excellent platform for further expansion into derivatives and other asset classes. Our organizations bring together very complementary businesses, and we see many new opportunities for growth in an era of unprecedented change and development for exchanges."

Magnus Bocker, Chief Executive Officer of OMX, commented:

"This combination creates a new leader in the exchange industry. By utilizing the combined entities' joint expertise and competencies we will create an outstanding platform for future growth. Issuers, members, information vendors and investors on both NASDAQ and OMX Nordic Exchange will all benefit from its new global context. The combination also provides benefits for OMX's global technology customer base, as it enables an increased focus on research and product development in the most important and fastest growing areas of the exchange technology market."

H. Furlong Baldwin, Chairman of NASDAQ, commented:

"We are each coming at this combination from a position of strength. At NASDAQ, we are privileged to be partnering with such a reputable institution as the OMX."

Urban Backstrom, Chairman of OMX, commented:

"For OMX, as a company that has always been known for its innovative and ground-breaking approach within the exchange industry, this is the natural next step. This will also strengthen the Nordic region as a financial center."

The Combined Group will have 2,349 employees in 22 countries with pro forma revenues for the financial year 2006 of more than $1.2 billion (SEK8.3 billion). The relative values of the companies under the terms of the Offer and based on NASDAQ's closing share price as of 23 May, 2007 are 58 percent NASDAQ and 42 percent OMX. The pro forma market capitalization of The NASDAQ OMX Group will be approximately $7.1 billion (SEK48.6 billion)(2), of which NASDAQ shareholders will own approximately 72 percent and OMX shareholders will hold approximately 28 percent as a result of the cash component of the Offer.(3)

The Combined Group will be governed by representatives from both NASDAQ and OMX under the leadership of Robert Greifeld, who will serve as Chief Executive Officer and Magnus Bocker, who will serve as President. The board of directors of the Combined Group will consist of 15 members, including nine representatives from NASDAQ, five representatives from OMX and the Chief Executive Officer of the Combined Group. The NASDAQ OMX share will be listed on NASDAQ and on OMX Nordic Exchange.

The Combination is unanimously recommended by the boards of directors of each of OMX and NASDAQ. Investor AB, Nordea Bank AB and Magnus Bocker, together representing approximately 16.6 percent of OMX's current issued ordinary share capital, have entered into irrevocable undertakings to accept the Offer and, if a mix and match facility is included in the Offer, depending on the structure and the terms of the facility, they will elect to receive all shares, subject to proration. Olof Stenhammar & Company, representing approximately 1.6 percent of OMX's current issued ordinary share capital, has expressed its support for the Combination and its intention to become a long term shareholder in the Combined Group. In addition, Hellman & Friedman, Silver Lake Partners, and Robert Greifeld have each agreed to vote their shares in favor of certain matters related to the Offer at the related NASDAQ shareholders' meeting, subject to the terms of NASDAQ's certificate of incorporation.

The Combination will create:



  *  PREMIER GLOBAL EXCHANGE COMPANY: NASDAQ is the premier US
     equities exchange, handling more shares and listing more
     companies than any other US exchange. NASDAQ's open and
     innovative market platform is the first choice for issuers
     as well as investors.  OMX Nordic Exchange is a highly
     integrated, efficient equities and derivatives market for
     leading European companies. Together, the NASDAQ and OMX
     exchanges will process an average daily volume of 7.4 million
     trades, representing a value of approximately $61 billion
     (SEK418 billion). The NASDAQ and OMX exchanges will have
     approximately 4,000 companies listed from 39 countries with
     an aggregate market capitalization of approximately $5.5
     trillion (SEK37.6 trillion);

  *  WORLD EXCHANGE TECHNOLOGY LEADER: OMX has been a pioneer in
     creating a truly integrated cross-border stock market. OMX
     also has created a world-renowned technology customer base
     of equity, debt, and derivatives exchanges with 60 clients
     in 50 countries worldwide, including Hong Kong, Singapore,
     Australia, and the US. NASDAQ pioneered electronic trading,
     and has continued to innovate over the last thirty years and
     now has the fastest, most efficient trading platform in
     the US. Together, the Combined Group will provide the
     technology for the world's increasingly competitive and
     demanding capital markets;

  *  Increased visibility and access to the global investment
     marketplace for issuers: Issuers will be associated with an
     innovative, future-focused company with blue-chip peers in
     all industry sectors. Listed companies will have access to
     a broad base of investors and deep pools of liquidity;

  *  A highly competitive derivatives market offering: OMX Nordic
     Exchange is Europe's third largest marketplace for trading
     and clearing equity-related derivatives. OMX's Nordic
     distribution network is extended through an international
     network of links to cooperating exchanges and clearinghouses.
     OMX's technology solutions are also being used by other
     leading derivatives exchanges around the world and will be
     a key asset in the Combined Group's opportunities to capture
     the high growth in derivatives trading globally;

  *  Enhanced strategic opportunities: The Combined Group will
     be the partner of choice for future cooperation and
     consolidation opportunities and have increased financial and
     managerial resources. The combined entity will be well
     positioned to drive organic growth and to continue to take a
     proactive role in sector consolidation, in Europe, emerging
     markets, the Americas and Asia; and

  *  Significant synergy potential: Both parties believe the
     Combination will create substantial value for shareholders,
     with total pre-tax annual synergies estimated at $150 million
     (SEK1,025 million). Of this amount, $100 million (SEK683
     million) constitutes estimated cost synergies and $50 million
     (SEK342 million) estimated revenue synergies. Cost synergies
     will be realized through the rationalization of IT systems
     and data centres, rationalization of non-IT functions, and
     reduced capital and procurement expenditure. Revenue
     synergies will be achieved through the creation of deeper
     liquidity pools, increased cross-border trading, increased
     international listings, packaged data products and enhanced
     technology sales.

The Combination is expected to create substantial value for shareholders and to be accretive to earnings per share in 2009.

                   Part II - Full Announcement

The boards of directors of The NASDAQ Stock Market, Inc. and OMX AB (publ) hereby jointly announce that they have entered into a Transaction Agreement to combine the two companies, creating the world's premier exchange and technology company. The Combination will be effected through a cash and stock tender offer by NASDAQ for all outstanding shares in OMX.

1. Background to and Reasons for the Offer and the Combination between NASDAQ and OMX

The exchange industry is undergoing a period of unprecedented change. These changes emanate from every aspect of our businesses, including an increasingly competitive environment, significant opportunities stemming from regulatory change, and the continued globalization of the investment industry. NASDAQ and OMX each have the strategic vision to be at the forefront of these changes, with a culture of innovation and flexibility, and the ambition to be an agile and global force in the rapidly growing and developing exchange industry.

Each of NASDAQ and OMX is an innovator of electronic trading with technology as the foundation of their businesses. The Combination brings together two companies with a common culture and vision of innovation, competitiveness and pioneering technological expertise. The NASDAQ OMX Group combines two highly complementary businesses, uniting NASDAQ's leading global brand, highly efficient electronic trading platform and track record of customer focused innovation with OMX's global technology services platform and customer base, efficient Nordic Exchange, multi-asset class capabilities and track record of successful cross-border exchange integrations.

NASDAQ and OMX have been drivers of competition in the exchange industry. NASDAQ has experienced 25 percent growth in matched trading volume across all US equities in the past year as regulatory developments have resulted in an increase in client demand for fast, efficient electronic trading. OMX has experienced 38 percent average annual growth in trading volumes in its cash markets business over the past three years, has substantially increased its market share in globally listed shares such as Nokia and Ericsson, and is providing technology platforms to new players in established markets. The Combination will leverage NASDAQ's and OMX's experiences to capitalize on new opportunities in the increasingly competitive exchange trading sector.

The Combined Group is expected to be the partner of choice for future cooperation and consolidation opportunities with increased financial and managerial resources. The Combined Group will be well positioned to drive organic growth and to continue to take a proactive role in sector consolidation, in Europe, emerging markets, the Americas and Asia.

OMX has been a pioneer in creating a truly integrated cross-border stock market. OMX has also created a world-renowned technology customer base of equities, debt, and derivatives exchanges with 60 clients in 50 countries worldwide, including Hong Kong, Singapore, Australia, and the US. NASDAQ pioneered electronic trading, and has continued to innovate over the last thirty years and now has the fastest, most efficient trading platform in the US. Together, we will provide the technology for the world's increasingly competitive and demanding capital markets. In addition, each company has a proven track record of participation in industry consolidation with successful integration of exchanges and trading platforms resulting in strong revenue and cost synergies.

This compelling Combination forms:



  *  The premier global exchange company:

    -- Together, NASDAQ and OMX will have an average daily
       trading volume of 7.4 million trades, representing a value
       of approximately $61 billion (SEK418 billion). NASDAQ and

       global equity capital.

  *  The world-leading provider of exchange technology:

    -- OMX has been a pioneer in creating a truly integrated

       worldwide, including Hong Kong, Singapore, Australia,

       continued to innovate over the last thirty years and now
       has the fastest, most efficient trading platform in the US.
       Together, NASDAQ and OMX will provide the technology for
       the world's increasingly competitive and demanding capital
       markets;

    -- OMX's extensive experience and expertise in providing
       state-of-the-art exchange technology worldwide to a
       sophisticated and global customer base, matched with
       NASDAQ's technology excellence and global brand and
       advanced services and support for innovative growth

    -- NASDAQ and OMX believe their focus on technology
       leadership and the combination of their expertise and
       brands will generate growth opportunities and additional
       sales of technology and related services globally.


  *  A highly competitive derivatives market offering:

    -- The OMX Nordic Exchange is Europe's third largest
       marketplace for trading and clearing equity-related
       derivatives with an annual trading volume of approximately
       140 million equity related derivatives contracts. OMX's
       Nordic distribution network is extended through an
       international network of links to cooperating exchanges
       and clearinghouses; and

    -- OMX's technology solutions are also being used by other
       leading derivatives exchanges around the world and will be
       a key asset in the combined group's opportunities to
       capture the high growth in derivatives trading globally.

  *  Enhanced data business with richer content and improved,
     global distribution:

    -- The Combined Group will leverage the strength of each
       organization's distribution capabilities to broaden the
       customer base for NASDAQ's and OMX's existing data products
       and to provide enhanced data tailored with value-added
       services to market participants;

    -- Through NASDAQ's distribution network of over 250 data
       vendors and OMX's over 100 data vendors, the Combined Group
       will be able to enhance its global market transparency; and

    -- The market data generated by the Combined Group will lever
       its product expertise and develop innovative data products
       and combined indices incorporating global complementary
       NASDAQ and OMX stocks and derivatives.

  *  Enhanced strategic opportunities:

    -- The Combined Group will be the partner of choice for future
       cooperation and consolidation opportunities with increased
       financial and managerial resources. The combined entity
       will be well positioned to drive organic growth and to
       continue to take a proactive role in sector consolidation,
       in Europe, emerging markets, the Americas and Asia; and


    -- Both NASDAQ and OMX will benefit from increased geographic,
       product and sectoral diversification and each will benefit
       from the other's strategic holdings in the industry.

  *  Significant synergy potential:

    -- Both parties believe the Combination will create
       substantial value for shareholders, with total pre-tax
       annual synergies estimated at $150 million (SEK1,025
       million). Of this amount, $100 million (SEK683 million)
       constitutes estimated cost synergies and $50 million
       (SEK342 million) estimated revenue synergies;

    -- Cost synergies will be realized through the rationalization
       of IT systems and data centres, rationalization of non-IT
       functions, and reduced capital and procurement expenditure;
       and

    -- Revenue synergies will be achieved through the creation
       of deeper liquidity pools, increased cross-border trading,
       increased international listings, packaged data products
       and enhanced technology sales.

    -- Total pre-tax restructuring and revenue investment costs
       are estimated at $150 million (SEK1,025 million) which
       will be incurred in the two years following completion
       of the Transaction.

Please see section 3 below for more information on synergies.

In summary, NASDAQ and OMX believe the Combined Group will create the world's premier global exchange technology company.

2. Benefits to Customers and Other Stakeholders

Both NASDAQ and OMX support the view that capital markets growth and development are promoted by transparent and efficient trading and technology development. This is achieved through close cooperation and collaboration between exchanges, issuers, members, investors and regulators. The efficiencies resulting from the Combination will be reflected in greater liquidity, reduced costs of trading, lower fees for members and investors and lower cost of capital for issuers. NASDAQ and OMX each have a track record of reducing operational costs while simultaneously improving customer service.

Investors and members will benefit from deeper pools of liquidity and higher trading volumes, a common IT infrastructure and interface for both exchange companies, access to more products and positive portfolio diversification.

Issuers will benefit from increased visibility and direct access to the largest investor base in the world. Increased trading activity and liquidity is also expected to reduce the cost of capital for issuers.

Technology customers will continue to benefit from the market insight the Combined Group derives from its direct participation in capital markets. Combined expertise will accelerate the development of the next generation of exchange technology at a time when investors and members are increasingly demanding multi-asset class trading platforms.

Data providers and vendors will receive richer content and improved global distribution. The market data will allow NASDAQ OMX to leverage its product expertise and develop a range of combined indices incorporating complementary stocks and derivatives from existing indices.

The Combination also provides a unique opportunity for the Nordic markets by placing them at the heart of the rapid consolidation of the exchange sector and becoming a key component of a world-leading company in the exchange industry. The OMX regulatory model will be unaffected by the Combination and the Combined Group will be well-positioned as an attractive partner with the capacity to compete effectively with other exchanges and continue consolidation across Europe and globally.

3. Benefits to Shareholders

NASDAQ and OMX have significant experience in integrating exchanges domestically and cross-border and delivering synergies. The Combination is expected to create significant value for both companies' shareholders through the realisation of pre-tax annual cost and revenue synergies of approximately $150 million (SEK1,025 million) from 2010. Annual pre-tax cost synergies are estimated at approximately $100 million (SEK683 million) in 2010. The Combination is expected to be accretive to earnings per share in 2009.

Based on their successful integration track records, NASDAQ and OMX believe that they will deliver the following cost synergies:



 * IT synergies of $66 million (SEK451 million)

   -- Integration of systems and platforms, merging the US operations of
      the two companies, and leveraging the Genium platform

 * Non-IT synergies of $34 million (SEK232 million)

   -- Rationalization of overlapping functions, services, premises, and
      reduction of capital and procurement expenditures

Both OMX and NASDAQ have established track records of delivering increased revenues through their acquisitions of other exchanges and trading platforms and valued-added service providers. Identified pre-tax annual revenue synergies are expected to amount to $50 million (SEK342 million) achieved over three years.



 * Trading and Information Services

   -- Increase in cross-border trading, cross-selling of data and new
      products and facilitation of cross membership

 * Issuer Services

   -- Attract new domestic and international listings as a result of the
      Combined Group's enhanced value proposition including brand, sector
      strengths and global reach. Introduce NASDAQ's issuer products and
      services to OMX issuer customers

Non-recurring pre-tax costs to achieve these synergies are expected to be $150 million (SEK1,025 million), which would be incurred in the two years following completion of the Transaction.

4. Company Structure and Branding

The Combined Group will be structured as a US holding company, named The NASDAQ OMX Group Inc., the shares of which will be listed on NASDAQ and on OMX Nordic Exchange.

The Combined Group's headquarters will be located in New York, which will also be the centre of operations for the group's US cash trading business. The Combined Group's technology business and Nordic trading business will continue to be managed as today. The Combined Group will establish a new London presence to capitalize on international growth opportunities.

The name and branding of the existing local exchanges within the Combined Group will remain unchanged.

5. Governance and Management

The board of directors of the Combined Group will consist of 15 members, including nine representatives from NASDAQ, five representatives from OMX and the Chief Executive Officer of the Combined Group. The Chairman will be elected by the board of directors of the Combined Group. The Deputy Chairman will be designated by OMX.

It is proposed that Robert Greifeld, currently President and Chief Executive Officer of NASDAQ, will serve as Chief Executive Officer of the Combined Group. It is proposed that Magnus Bocker, currently President and Chief Executive Officer of OMX, will become President of the Combined Group.

The Combined Group will have a balanced management team and organization reflecting the experience, expertise and activities that each party brings to the Combination.

6. Employees

OMX and NASDAQ each operate strong exchange companies which are recognized as being among the best for employees in the market. Following the proposed Transaction, the Combined Group's strategy will be to grow volume and broaden its customer base, combining the strengths of both companies. In this context, the proposed Transaction will create enhanced career opportunities for employees of the Combined Group. All existing contracts will be honored.

Separately from the Offer, NASDAQ and OMX will offer participants of OMX's existing stock option plans and share match plans fair treatment in respect of their entitlements under the respective plans.

7. Regulatory Issues

The Combination of NASDAQ and OMX will require consent or approval from relevant financial supervisory authorities and competition authorities.

Each of the Combined Group's markets will continue to be regulated in accordance with local requirements. Specifically, OMX's markets will continue to be regulated by their existing regulators, and the SEC will continue to regulate NASDAQ's US markets only. The Sarbanes-Oxley Act will continue to be exclusively applicable to companies registered in the US.

8. Dividend Policy

The dividend policy of the Combined Group will be determined by the board of the Combined Group.

9. Financial Effects of the Offer

The Transaction is expected to create substantial shareholder value and be accretive to earnings per share in 2009.

10. Financing of the Offer

Assuming full acceptance of the Offer, approximately 60.6 million new NASDAQ shares will be issued pursuant to the Offer and the total cash consideration amount payable by NASDAQ to OMX shareholders will be approximately $1.7 billion (SEK11.4 billion).

The Offer will not be subject to any conditions concerning the availability of financing. Bank of America and JPMorgan Chase Bank, N.A. (the "Banks") have agreed to finance the cash consideration of the Offer pursuant to a commitment letter subject to all parties entering into definitive documentation. However, if definitive documentation is not entered into by the date on which the Offer is launched, the Banks will finance the cash consideration of the Offer by means of an interim loan agreement (the "Interim Loan Agreement") which provides for committed funds and which is attached as an exhibit to the commitment letter.

Drawdown pursuant to the Interim Loan Agreement is subject to the conditions of the Offer being satisfied or waived (where such waiver requires consents from the Banks in certain cases and under certain circumstances). The additional conditions to drawdown under the Interim Loan Agreement, which NASDAQ and its owners in practice control, are essentially that:



 * NASDAQ and its current subsidiaries execute collateral agreements and
   guarantees, deliver stock certificates and stock powers and make
   relevant filings and recordations;

 * NASDAQ issues a promissory note in favor of each Bank evidencing such
   Bank's loans;

 * NASDAQ delivers documents evidencing the authority and capacity to
   enter into the Interim Loan Agreement and pertaining documentation,
   including legal opinions and certificate of good standing; and

 * NASDAQ is not in breach of certain limited key representations and
   events of default under the Interim Loan Agreement (including that the

11.1 The Offer

The Offer to the OMX shareholders consists of a mixture of cash and new NASDAQ shares as consideration which values each OMX share at SEK208.1 based on the assumptions set out in section 11.2 below. For every 100 OMX shares tendered, each OMX shareholder will receive SEK9,430 in cash and 50.2 new NASDAQ shares, equivalent to 0.502 NASDAQ shares and SEK94.3 in cash per OMX share.

NASDAQ is offering each OMX shareholder: (4)



 -- In respect of approximately 45.3 percent of the number of OMX shares
    tendered by such shareholder: SEK208.1 per OMX share in cash (the
    "Cash Consideration"); and

    of OMX shares tendered by such shareholder: 0.918 new NASDAQ shares
    (the "Share Consideration"), equivalent to a value of SEK208.1 per OMX
    share.

NASDAQ reserves the right to introduce a mix and match facility which will enable OMX shareholders to elect to tender a higher proportion of their OMX shares in return for the Cash Consideration or to tender a higher proportion of their OMX shares in exchange for the Share Consideration, subject to matching elections by other OMX shareholders. The total number of new NASDAQ shares to be issued under the Offer would not be varied as a result of elections made under such mix and match facility.
