DEERFIELD, IL - June 19, 2012 - Walgreen Co. (NYSE: WAG) (NASDAQ: WAG), the largest drug store chain in the U.S., and Alliance Boots GmbH, the leading international pharmacy-led health and beauty group, today announce that they have entered into a strategic transaction designed to bring together the strengths and expertise of both companies to create the first global pharmacy-led, health and wellbeing enterprise.

This transaction will bring together two great companies with iconic brands, complementary geographic footprints, shared values and a heritage of trusted healthcare services, through pharmaceutical wholesaling and community pharmacy care, dating back over 100 years. Walgreens and Alliance Boots are the largest retail pharmacy, health and daily living destinations in the U.S. and Europe, respectively, and together they would be:

- the global leader in pharmacy-led, health and wellbeing retail with over 11,000* stores in 12* countries
- the largest global pharmaceutical wholesale and distribution network with over 370* distribution centers delivering to more than 170,000* pharmacies, doctors, health centers and hospitals in 21* countries
- the world's largest purchaser of prescription drugs and many other health and wellbeing products

Together Walgreens and Alliance Boots would have:

- unmatched supply chain and procurement expertise, offering customers innovative solutions and optimal efficiencies
- an unparalleled portfolio of retail and business brands (Walgreens, Duane Reade, Boots and Alliance Healthcare), as well as increasingly global health and beauty product brands (No7, Botanics and Boots Laboratories)
- diversified and robust profit pools across the U.S., Europe and key emerging markets
- a unique platform for growth in developed and emerging markets

Walgreens will invest approximately $6.7 billion in cash and stock (comprised of $4.0 billion in cash and 83.4 million shares) in exchange for a 45% equity ownership stake in Alliance Boots. Walgreens will have the option to proceed to a full combination by acquiring the remaining 55% of Alliance Boots in approximately three years' time. At the current Walgreens share price and at a $1.55=£1 exchange rate, the second step of the transaction would be valued at approximately $9.5 billion in cash and stock, plus the assumption of Alliance Boots then-outstanding debt. Completion of the initial investment, which is subject to various regulatory approvals, is expected to take place by September 1, 2012.

The Boards of Directors of Walgreens and Alliance Boots have unanimously approved the transaction. Upon the completion of Walgreens initial investment in Alliance Boots, Gregory Wasson, President and Chief Executive Officer of Walgreens, Wade Miquelon, Executive Vice President and Chief Financial Officer, Thomas Sabatino, Executive Vice President and General Counsel, and Robert Zimmerman, Senior Vice President and Chief Strategy Officer, will join the Alliance Boots Board of Directors. In addition, Stefano Pessina, Executive Chairman of Alliance Boots, and Dominic Murphy, Director and Member of KKR & Co. L.P., will join the Walgreens Board of Directors. Alliance Santé Participations S.A., of which Stefano Pessina is a director and whose ultimate ownership is a family trust, will hold a significant stake in Walgreens, which it intends to hold for the long term. KKR, through its funds, will also be an important shareholder of Walgreens.

The transaction is expected to be accretive to Walgreens net earnings per diluted share in the first year following completion of the initial step of the transaction, by approximately $0.23 to $0.27, excluding one-time transaction costs. Walgreens expects combined synergies across both companies to be between $100 million and $150 million in the first year and $1 billion by the end of 2016. The most significant short-term and long-term opportunities are:

• procurement synergies, including prescription drug, OTC, front-of-store purchasing and indirect spend; and
• revenue synergies, as a result of introducing Alliance Boots product brands to Walgreens and Duane Reade stores and sharing of best practices, particularly in pharmacy operations, health and wellness services and logistics.

The transaction has been structured to allow synergies to be realized by the respective management teams working closely together on key projects, while progressing to full integration in approximately three years' time. Walgreens and Alliance Boots believe that this transaction structure maximizes the potential for value creation, while minimizing the initial business disruption and allowing time for thoughtful integration planning.

Gregory Wasson, President and CEO of Walgreens, said, "At Walgreens, our mission is to be America's first choice for health and daily living - helping our customers to live well, stay well and get well. Today's announcement represents an exciting opportunity to accelerate our five core strategies and advance that mission - in the U.S. and now internationally. We are bringing together the strengths and expertise of each company to create a worldwide healthcare platform for the future that can provide innovative ways to address global health and wellness challenges.

"We are looking forward to working with Alliance Boots to leverage our combined strengths and provide an even broader range of innovative, cost-effective products and services to patients and customers across the healthcare landscape. Together we will be ideally positioned to expand our customer offerings in our existing markets and become the health and wellbeing partner of choice in emerging markets."

Stefano Pessina, Executive Chairman of Alliance Boots, commented, "This strategic transaction represents a further vital step in achieving our vision of becoming a global healthcare leader. We believe that it will bring clear benefits to all stakeholders, creating significant and sustainable industrial value through synergies and the deployment of our joint expertise. The fit is natural, Walgreens consumer profile in the U.S. is similar to Boots in the UK in many ways: a trusted and much-loved pharmacy brand with a strong heritage. Our pharmaceutical wholesale businesses will provide their logistics know-how to Walgreens and are well placed to be one of the growth engines of the new enterprise.

"Today's announcement is testimony to the great track record and accomplishments of the Alliance Healthcare and Boots teams that have delivered strong growth since the creation of Alliance Boots six years ago and its subsequent privatization. I strongly believe that this transaction offers further significant growth opportunities and marks a very positive milestone for the healthcare industry as a whole."

With the exercise of the option by Walgreens to proceed to a full combination, the new combined company will be a true world leader in its field, with the combined scale, expertise and financial strength to grow rapidly in existing markets and fast growing emerging markets across the globe, within existing business lines and in new segments. These growth opportunities are expected to be key drivers of long-term shareholder value.

The pharmacy-led retail and wholesale businesses of both companies will continue to operate under their well-known and trusted brand names. Upon completion of the second step of the transaction, the name of the new combined entity will reflect the strong heritage of both companies.

Given the complementary geographic footprints of Walgreens and Alliance Boots, there are no plans for job reductions at either company as a result of the transaction. Walgreens will maintain its existing headquarters in Deerfield, Illinois; and Alliance Boots remains committed to its current support offices across Europe, including in the UK, as well as keeping the Boots operational hub in Nottingham, England.

Transaction Structure

Under the terms of the agreement announced today, Walgreens will pay a total of $6.7 billion to acquire a 45% equity interest in Alliance Boots. This payment will consist of $4.0 billion in cash and 83.4 million shares of Walgreens common stock. This is equivalent to $2.7 billion, at the Walgreens closing share price of $31.96 on June 18, 2012. The owners of Alliance Boots will enter into lock-up agreements of varying lengths with respect to the Walgreens shares they will acquire in the transaction. Walgreens expects to complete its initial investment in Alliance Boots by September 1, 2012, at which time it will account for its interest in Alliance Boots using the equity method of accounting.

During the six-month period beginning two and a half years after the initial closing, Walgreens has the option, but not the obligation, to elect to proceed to a full combination and acquire the remaining 55% equity interest in Alliance Boots. In conjunction with such an election, Walgreens would seek shareholder approval of the transaction in accordance with stock exchange rules. If the option is exercised, Walgreens will pay £3.1 billion (equivalent to $4.9 billion**) in cash and issue 144.3 million shares for the remaining equity of Alliance Boots, subject to the price of Walgreens shares of common stock at that point not being below $31.18 per share. If the price is below this level, the difference in value will be made up by a cash payment or the issuance of additional shares of common stock at Walgreens election. In the event that Walgreens does not exercise its option, under certain circumstances, its ownership of Alliance Boots will reduce from 45% to 42% in exchange for nominal consideration to Walgreens.

Walgreens initial investment and option excludes the Alliance Boots minority interest in Galenica, the Swiss healthcare group. The Alliance Boots investment in Galenica will continue to be owned by Alliance Boots and its existing shareholders for the benefit of those shareholders.

Commitments for a $3.5 billion bridge facility have been received from Goldman, Sachs & Co. and Bank of America Merrill Lynch and are subject to customary conditions.
