Express Scripts to Distribute Definitive Proxy Materials to Caremark Stockholders

Express Scripts Urges Caremark Stockholders to Vote the GOLD Proxy Card Against the Acquisition By CVS 


ST. LOUIS, Jan. 24  /PRNewswire-FirstCall/ -- Express Scripts, Inc. (NASDAQ:ESRX) today announced that it will commence distributing its definitive proxy materials to all Caremark Rx, Inc. (NYSE:CMX) stockholders in connection with Caremark's special meeting of stockholders to be held on February 20, 2007.  Express Scripts also announced that it will distribute the following letter to Caremark stockholders:

  January 24, 2007

                     PROTECT YOUR CAREMARK INVESTMENT
                   VOTE AGAINST THE PROPOSED CVS MERGER

  Dear Caremark Stockholder:



Since we announced our superior offer to acquire Caremark on December 18, 2006, we have repeatedly appealed to Caremark's Board of Directors to engage with Express Scripts.  To date, your Board of Directors has rejected our superior offer and refused even to engage in a conversation with us about our superior offer.  How can Caremark's Board of Directors fail to invite Express Scripts in to validate our superior offer?

Given that the Caremark Board of Directors has stonewalled our efforts to meet for reasons unknown, we have taken a number of significant steps to move forward with our superior offer and appeal directly to Caremark stockholders:

  -- Launched our superior exchange offer based on the terms offered to
     Caremark's Board of Directors;
  -- Executed commitment letters with Citigroup Corporate and Investment
     Banking and Credit Suisse to fully finance the proposed transaction;
  -- Filed the premerger notification and report form pursuant to the Hart-
     Scott-Rodino Antitrust Improvements Act; and
  -- Nominated a slate of independent directors to Caremark's Board of
     Directors.



Express Scripts is ready to begin due diligence immediately.  Instead of considering all options, Caremark's Board of Directors is adhering to a highly unusual interpretation of the $675 million breakup fee.  Caremark is treating the fee as a "price of admission" for a conversation, rather than as a termination fee which will be paid to Caremark under certain circumstances upon termination of its merger agreement with CVS.  How can this approach, which discourages higher offers from third parties, be in the best interests of Caremark stockholders?

VOTE YOUR GOLD PROXY CARD AGAINST THE CVS TRANSACTION TODAY

We urge you to VOTE AGAINST the Caremark Board's proposal to adopt the plan of merger with CVS and send a message to the Caremark Board that it must engage in a discussion with Express Scripts about our clearly superior offer.

VOTE YOUR GOLD PROXY CARD AGAINST THE CVS ACQUISITION AND PROTECT YOUR RIGHT TO RECEIVE A SUPERIOR OFFER FOR YOUR CAREMARK SHARES BEFORE VOTING, CONSIDER THE FOLLOWING:

A New Week, A New Synergy Number

The synergies claimed in the CVS acquisition of Caremark have grown inexplicably since our superior offer was announced to now include $800 million to $1 billion of revenue synergies never previously communicated to the market.   Nevertheless, there has been no promise that these purported returns will be passed on to Caremark stockholders, as is customarily demanded by the Board of the acquired company.  Furthermore, revenue is not the same as profit - no matter how great the supposed revenue synergy, there's no way to know what that would mean for your bottom line.  In addition, Caremark stockholders have been offered a special dividend which works out to $1.09 when you subtract the portion the stockholders are funding themselves given their 45.5% ownership of the combined CVS/Caremark.

On the other hand, Express Scripts has confidence in our estimated synergies for an Express Scripts/Caremark combination.  If given the opportunity, we could present our case to Caremark.  However, Caremark's response has been to dismiss our synergies sight unseen, instead of affirming them through a coordinated process with us.

Caremark stockholders are being offered CVS stock as currency in a transaction that will dilute the trading multiple of the shares they own in Caremark.  In the proposed Express Scripts transaction, you would receive $29.25 in cash and 0.426 shares of Express Scripts stock for each share of Caremark stock.

As you weigh the uncertainty and future potential of the proposed CVS- Caremark transaction, we urge you to consider this fact: The total return for stockholders of Express Scripts has outstripped the total return for stockholders of CVS by over 1,000% over the past 10 years.

History Shows - Vertical Transactions Fail and Destroy Value

History is a good indicator that putting two PBMs together delivers superior value to stockholders, plan sponsors and patients.  We know from our previous discussions with Caremark management that they believe in putting PBMs together and understand the synergy benefits.  History also dictates that, over time, vertical transactions - like the proposed acquisition of Caremark by CVS - destroy value.  There is a fundamental difference between business models and interests of PBMs and retailers which means conflicts of interest in drug choice, utilization, distribution channel and working with competing retailers.  Vertical transactions do not put the customer first - that's why they lose.

Where value has been destroyed, it was not because the PBMs were bad companies, but because their competitiveness and ability to grow in their markets was constrained by operating within the vertical confines of the acquiring company.  For example, when PCS was eventually returned to PBM ownership in the form of AdvancePCS, the company grew steadily.  The same is true of DPS under Express Scripts ownership - an example of how successful acquisitions and strong organic growth drive increased value for stockholders. If history repeats itself, the CVS proposal could destroy significant stockholder value for CVS and Caremark.  Caremark stockholders could lose over $8 per share.  It's value destruction all over again.

Proven and Inherent Value in Horizontal Transactions

Since 1998, Express Scripts has created real value for stockholders by making five successful horizontal acquisitions and then integrating them into its business.  As we noted earlier, both the Boards of Express Scripts and Caremark have seriously considered a value enhancing horizontal merger on numerous occasions over the last six years.  At the end of the day, the driving consideration was whether an agreement could be reached on the premium required to acquire the target company.  Given that history, why should you settle for a CVS deal with little to no premium?  Express Scripts continues to believe that the strategic and financial merits of a combination with Caremark are compelling and offer greater opportunity in terms of growth and value creation for stockholders.  Express Scripts has enjoyed the strongest claims growth throughout its most recent PBM acquisitions, notwithstanding any accusations to the contrary.  Furthermore, each time Express Scripts has acquired another PBM, the combined businesses increased in the number of customers beyond what both had at the time of acquisition.  Successful acquisitions and strong organic growth are core competencies of Express Scripts and have driven increased stockholder value.

Retention by Innovation

The Express Scripts business model delivers proven organic growth.  We are meeting and exceeding expectations and continue to produce outstanding results for stockholders, plan sponsors and patients.  Our plan sponsors and patients are continually offered innovative products and services, and this execution of innovation underpins our first rate client retention.  We will continue to operate in a dynamic environment where our ongoing innovation and execution help to fuel our growth in the marketplace.

An Express Scripts-Caremark combination would pool our strengths in innovation, resulting in even better products and services.  We will meet and lead market needs.  The horizontal integration of Express Scripts and Caremark would allow for significant upgrades in expertise, bringing together the best and brightest PBM experts to help plan sponsors meet upcoming challenges in pharmacy management.  The CMX/CVS proposed vertical integration leaves expertise "as is", with little or no overlap except the prospect of selling retail products to patients as they wait in line for their prescriptions to be filled.

Your vote is important, no matter how many or how few Caremark shares you own.  YOU ARE THE TRUE OWNERS OF CAREMARK - DEMAND THAT THE CAREMARK BOARD MAXIMIZE STOCKHOLDER VALUE BY VOTING YOUR GOLD PROXY CARD AGAINST THE CVS TRANSACTION.

  Sincerely,

  /s/ George Paz
  George Paz
  President, Chief Executive Officer and Chairman of the Board
