UNITED PARCEL SERVICE AND TNT EXPRESS TO CREATE A GLOBAL LEADER

IN THE LOGISTICS INDUSTRY

Transaction Highlights

Compelling Strategic Rationale with Significant Benefits for All Stakeholders

Page 1 of 8

Atlanta, GA / Hoofddorp, March 19, 2012 – United Parcel Service, Inc. (NYSE: UPS) and TNT Express N.V. (NYSE Euronext: TNTE) today jointly announce that they have reached agreement on a recommended all-cash public offer of €9.50 per ordinary share by UPS for TNT Express (the “Offer”). TNT Express’ Executive and Supervisory Boards unanimously intend to support and recommend the Offer.

The offer price of €9.50 (including any dividend or other distribution other than the financial year 2011 final dividend payment not exceeding €0.004 per share) represents a 53.7% premium to TNT Express’ unaffected share price on February 16, 2012 of €6.18, the day before TNT Express and UPS announced their ongoing discussions. The Offer values the issued and outstanding share capital of TNT Express at €5.16 billion ($6.77 billion⁽¹⁾).

The combination of UPS and TNT Express will create a global leader in the logistics industry, with annual revenues of more than €45 billion ($60 billion⁽¹⁾) and will deliver significant benefits for the shareowners, customers, employees and other stakeholders of both companies.

Together, UPS and TNT Express will offer customers an enhanced, integrated global network that will provide greatly enhanced service to customers throughout the world. In addition, the two companies are a strong cultural fit given their intense focus on customer service, operational excellence, employee engagement and good corporate citizenship.

The proposed transaction will accelerate UPS’s growth strategy and increase its geographic diversity and ability to provide customers comprehensive solutions. UPS currently estimates annual run-rate pre-tax cost synergies of approximately €400 to €550 million ($525 to $725 million⁽¹⁾) a year, achieved by the end of the fourth year after closing. UPS believes that the cumulative pre-tax implementation costs related to achieving these synergies will be approximately €1 billion ($1.31 billion⁽¹⁾) over the four-year integration period.

UPS and TNT Express believe this transaction will significantly enhance their ability to serve their customers’ complex global logistics needs. Following the transaction, around 36% of the combined group’s revenues will be generated outside the United States, up from 26% today at UPS. The combination underlines UPS’s long-standing commitment to Europe, where it has maintained a presence since 1976, by strengthening its product capabilities through the addition of TNT Express’ leading Intra-Europe road freight network. The combination also enhances UPS’s existing position in fast growing regions such as Asia-Pacific and Latin America.

Service lies at the heart of this proposed transaction. With a combined network and enhanced IT platforms, customers will have access to deeper product capabilities and broader reach through the expanded geographies served, giving them more choice and flexibility to support the growth and globalization of their businesses. The combination also will offer employees greater opportunities to be part of a global, growing and respected business.

“With this combination, both UPS and TNT Express will significantly enhance their ability to serve our combined customers’ complex global logistics needs. The additional capabilities and broadened global footprint will support the growth and globalization of our customers’ businesses. At the same time, this positions us for future growth, which will benefit our employees and shareowners,” said Scott Davis, UPS Chairman and CEO.

“This combination will significantly enhance the capabilities of two strong companies. I am convinced that together we will be the supplier and employer of choice in the express delivery industry. Our customers will greatly benefit from our enhanced combined service offerings. To my 77,000 colleagues I say that the combination will create unique opportunities for development and growth in which we can participate,” said Marie-Christine Lombard, TNT Express CEO.

Unanimous Support from Executive and Supervisory Boards of TNT Express

After careful consideration of all of TNT Express’ strategic alternatives, the Executive and Supervisory Boards of TNT Express believe this transaction is in the best interests of the company and its stakeholders and intend to support and unanimously recommend the Offer for acceptance to TNT Express’ shareholders. Goldman Sachs International has issued a fairness opinion to the Supervisory and Executive Boards of TNT Express and Lazard B.V. has issued a fairness opinion to the Supervisory Board, in each case to the effect that, as of today, the offer price is fair to the TNT Express shareholders from a financial point of view.

Irrevocable from PostNL

PostNL N.V., holder of approximately 29.8% of the outstanding shares of TNT Express, has committed itself to tender its shares under the offer if and when made. The irrevocable contains certain customary undertakings and conditions.

Corporate Governance and Integration

UPS recognizes that TNT Express’ employees will play a pivotal role in the success of the combined entity and they will be treated accordingly. All employee rights, covenants, and benefits under current ownership will be respected. As a result of the proposed transaction, the employees of the combined group will have broader career opportunities based on our future growth expectations.

UPS has a long-standing history of developing people through its promotion from within philosophy, giving employees the opportunity to hold positions at the highest levels of the company. Additionally, UPS and TNT Express share a common business culture and believe that a combination of the businesses will prove attractive to employees. Throughout integration, the selection and appointment of staff for any function within the newly combined entity, will be subject to applicable laws, and be based on the “best person for the job” principle. In case of potential consequences for employees of the combination, the principle of fairness will be applied as to the impact of redundancies on TNT Express and UPS staff.

UPS spent considerable time evaluating potential integration opportunities as it evaluated this transaction. In the coming months, UPS and TNT Express will work together through the establishment of an Integration Committee to develop plans to combine both companies’ strong networks and customer relationships while maintaining the same level of quality and service associated with both companies. UPS is committed to maintaining an ongoing dialogue with, and to closely involve, employee representatives in line with legal requirements and UPS and TNT Express’ leading employment practices.

UPS recognizes the expertise of TNT Express’ leading road freight network in Europe. It also appreciates the leading role that the road freight management will occupy in the combined group. UPS undertakes to create a meaningful center of excellence for marketing, sales, and operations in The Netherlands. UPS recognizes the significant value of TNT Express’ operations, assets and people in Liège and will seek to continue the future utilization of these operations, assets and people within the combined group.

TNT Nederland B.V. will maintain the mitigated structure regime. After successful completion of the Offer, the Supervisory Board of TNT Express will be composed of at least three members identified by UPS and two members of the current Supervisory Board of TNT Express, namely Shemaya Levy and Margot Scheltema. These two members will function as independent Supervisory Directors within the meaning of the Dutch Corporate Governance Code and shall continue to serve on the Supervisory Board until the third anniversary of the settlement date.

Notice to US holders of TNT Express Shares

The Offer will be made for the securities of a Dutch company and is subject to Dutch disclosure requirements, which are different from those of the United States. Some of the financial information included in this announcement has been prepared in accordance with International Financial Reporting Standards and thus may not be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States. The Offer will be made in the United States pursuant to the applicable US tender offer rules and otherwise in accordance with the requirements of the Decree. Accordingly, the Offer will be subject to disclosure and other procedural requirements, including with respect to withdrawal rights, offer timetable, settlement procedures and timing of payments, that are different from those applicable under US domestic tender offer procedures and law.

The receipt of cash pursuant to the Offer by a US holder of TNT Express shares may be a taxable transaction for US federal income tax purposes and under applicable state and local, as well as foreign and other tax laws. Each holder of TNT Express shares is urged to consult his independent professional advisor immediately regarding the tax consequences of acceptance of the offer.

It may be difficult for US holders of TNT Express shares to enforce their rights and claims arising out of the US federal securities laws, since TNT Express is located in a country other than the United States, and some or all of its officers and directors may be residents of a country other than the United States. US holders of TNT Express shares may not be able to sue a non-US company or its officers or directors in a non-US court for violations of the US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court’s judgment.

In accordance with normal Dutch practice and pursuant to Rule 14e-5(b) of the US Exchange Act, UPS or its nominees, or its brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase, TNT Express shares outside of the United States, other than pursuant to the Offer, before or during the period in which the Offer remains open for acceptance. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases will be disclosed as required in the Netherlands, will be reported to the Netherlands Authority for the Financial Markets (Stichting Autoriteit Financiële Markten) and disclosed in the offer memorandum or by press release.
