January 4, 2007

Dear Per-Se Stock Option and Restricted Stock Unit Holders,

The stockholders meeting to vote on a proposal to adopt the previously announced Agreement and Plan of Merger (the “Merger Agreement”), which provides for the acquisition (the “Merger”) of Per-Se Technologies, Inc. (“Per-Se”) by McKesson Corporation (“McKesson”), is scheduled to occur on January 24, 2007. If the stockholders adopt the Merger Agreement, such adoption (or, depending on the applicable equity-based compensation plan, the consummation of the Merger) will constitute a “Change in Control” of Per-Se under its equity-based compensation plans. This letter briefly summarizes how your Per-Se stock options and restricted stock units (“RSUs”) will be treated in connection with the Merger. More detailed information about how you will be paid for your options and RSUs will be provided closer to the closing of the Merger.

Please note that this information is merely a general summary, and is qualified in all respects by the more specific provisions set forth in the Merger Agreement, the applicable Per-Se equity-based compensation plans and the related stock option and RSU agreements. This letter does not amend any of the foregoing. More information concerning the acquisition is available in the Proxy Statement, dated December 21, 2006, which was sent to Per-Se stockholders entitled to vote at the stockholders meeting and may be found on the Per-Se website.

Stock Options

At the effective time of the Merger, each outstanding option to purchase shares of our common stock with an exercise price of less than $28.00 per share, whether or not then exercisable or vested, will be canceled and converted into the right to receive a cash payment equal to the difference between $28.00 and the exercise price per share of the option, multiplied by the number of shares of Per-Se common stock subject to the option, without interest and less any applicable withholding tax. Each outstanding option with an exercise price equal to or greater than $28.00 per share will be canceled without payment for such option and will have no further force or effect.

Use the following formula to calculate the amount payable for each of your stock options:

•

$28.00 minus the exercise price per share multiplied by number of shares minus applicable withholding taxes.

Performance-Based Restricted Stock Units

At the effective time of the Merger, each outstanding performance-based RSU, whether vested or unvested, will be canceled and converted into the right to receive a cash payment equal to $28.00 multiplied by the number of shares of Per-Se common stock subject to such RSU (based on the actual Total Shareholder Return Targets as of the effective time of the Merger), without interest and less any applicable withholding tax.

Use the following formula to calculate the amount payable for your performance-based RSUs:

•

$28.00 multiplied by the number of shares of Per-Se common stock subject to such RSU (based on the actual Total Shareholder Return Targets as of the effective time of the Merger) minus applicable withholding taxes.

Service-Based Restricted Stock Units

Each outstanding service-based RSU will cease to represent a right to receive, upon settlement, shares of Per-Se common stock and will instead be assumed by McKesson and converted into the right to receive, upon settlement, a number of shares of McKesson common stock equal to the number of shares of Per-Se common stock subject to such service-based RSU multiplied by the ratio of $28.00 to the closing price of McKesson common stock on the closing date of the Merger.

Use the following formula to calculate the number of shares of McKesson common stock that will be subject to your converted service-based RSUs:

•

The number of shares subject to the award multiplied by $28.00 divided by the closing price of McKesson common stock on the closing date of the Merger equals the number of shares of McKesson common stock subject to the converted RSU.

If you hold converted service-based RSUs, you will be credited with your service with Per-Se for vesting purposes but your vesting schedule will not change. If you are terminated without “cause” (as defined in the Per-Se 2006 Long-Term Incentive Plan) within two years following the closing of the Merger, then your converted service-based RSUs will immediately vest and become payable in the applicable number of shares of McKesson common stock.

Exercising Stock Options Before the Merger Closes

If you are not a “Designated Individual” under Per-Se’s Stock Trading Policy and would like to exercise your vested stock options before the closing of the Merger, you may do so by contacting Merrill Lynch customer service at (877) 767-2404. Merrill Lynch handles this process for Per-Se option holders.

If you are a Designated Individual, then please consult separate communications from Per-Se’s Legal Department as to whether a “window period” is open for purposes of trading in Per-Se common stock, including trades in connection with stock option exercises. The window period currently is not open for Designated Individuals.

Determining the Number of Your Stock Options and RSUs

If you have questions regarding how many shares are subject to your stock options or RSUs, you may call Merrill Lynch customer service at (877) 767-2404.

For further information regarding our program with Merrill Lynch, please consult the Per-Se Intranet. Information can be found in the “Corporate” section under “Treasury.”

General Information

Any cash payment to you in respect of your stock options or RSUs, if any, generally will be ordinary income to you under the U.S. tax code, taxable in its entirety at ordinary income tax rates. We recommend that you consult your own tax advisor as to the tax consequences of the Merger in your particular circumstances.
