Offer to Purchase for Cash

Up to 50,000,000 Shares of its Common Stock

at a Purchase Price not greater than $50.00

nor less than $43.00 per Share

THE OFFER, WITHDRAWAL RIGHTS AND PRORATION PERIOD WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON MONDAY, NOVEMBER 14, 2005, UNLESS THE OFFER IS EXTENDED.

          HCA Inc., a Delaware corporation (the “Company” or “HCA”), invites our shareholders to tender up to 50,000,000 shares of our common stock, $0.01 par value per share (the “Shares”), for purchase by us at a price not greater than $50.00 nor less than $43.00 per Share, net to the seller in cash less any applicable withholding taxes, without interest, upon the terms and subject to the conditions described in this Offer to Purchase and the accompanying Letter of Transmittal (which together, as they may be amended or supplemented from time to time, constitute the “Offer”). We will select the lowest purchase price (the “Purchase Price”) that will allow us to buy 50,000,000 Shares or, if a lesser number of Shares is properly tendered, all Shares that are properly tendered and not properly withdrawn. All Shares acquired in the Offer will be acquired at the same price.

          Only Shares properly tendered at prices at or below the Purchase Price selected by us, and not properly withdrawn, will be purchased. However, because of the “odd lot” priority, proration and conditional tender provisions described in this Offer to Purchase, all of the Shares tendered at or below the Purchase Price may not be purchased if more than the number of Shares we seek are properly tendered. Shares tendered but not purchased in the Offer will be returned to the tendering shareholder at our expense promptly following the Expiration Date (as defined in the Introduction). See Section 3.

          We reserve the right, in our sole discretion, to purchase more than 50,000,000 Shares pursuant to the Offer, subject to certain limitations and legal requirements. See Sections 1 and 15.

          THE OFFER IS NOT CONDITIONED ON ANY MINIMUM NUMBER OF SHARES BEING TENDERED. HOWEVER, THE OFFER IS SUBJECT TO OTHER CONDITIONS, INCLUDING AMENDING OUR EXISTING CREDIT FACILITY OR REFINANCING IT PURSUANT TO THE TERMS AND CONDITIONS CONTAINED IN THE REFINANCING COMMITMENT LETTER (AS DEFINED IN SECTION 9) AND OBTAINING THE NECESSARY FINANCING FOR THE OFFER PURSUANT TO THE TERMS AND CONDITIONS CONTAINED IN THE TERM FACILITY COMMITMENT LETTER (AS DEFINED IN SECTION 9). See Sections 7 and 9.

          The Shares are listed and traded on the New York Stock Exchange under the symbol “HCA.” On October 12, 2005, the last full trading day before the announcement of the Offer, the last reported sale price of the Shares was $46.69 per Share. Shareholders are urged to obtain current market quotations for the Shares. See Section 8.

          OUR BOARD OF DIRECTORS HAS APPROVED THE OFFER. HOWEVER, NEITHER WE NOR OUR BOARD OF DIRECTORS, THE LEAD DEALER MANAGER, THE DEALER MANAGER, THE INFORMATION AGENT OR THE DEPOSITARY ARE MAKING ANY RECOMMENDATION TO YOU AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING YOUR SHARES OR AS TO THE PRICE AT WHICH YOU MAY CHOOSE TO TENDER YOUR SHARES. YOU MUST MAKE YOUR OWN DECISION AS TO WHETHER TO TENDER YOUR SHARES AND, IF SO, HOW MANY SHARES TO TENDER AND THE PRICE OR PRICES AT WHICH YOU WILL TENDER THEM. IN DOING SO, YOU SHOULD READ CAREFULLY THE INFORMATION IN THIS OFFER TO PURCHASE AND IN THE RELATED LETTER OF TRANSMITTAL, INCLUDING THE PURPOSES AND EFFECTS OF THE OFFER. SEE SECTION 2. YOU SHOULD DISCUSS WHETHER TO TENDER YOUR SHARES WITH YOUR BROKER, IF ANY, OR OTHER FINANCIAL ADVISOR.

          OUR DIRECTORS AND EXECUTIVE OFFICERS HAVE ADVISED US THAT THEY DO NOT INTEND TO TENDER SHARES PURSUANT TO THE OFFER. SEE SECTION 12.

          Questions and requests for assistance may be directed to Georgeson Shareholder Communications, Inc., our Information Agent, and Merrill Lynch & Co., our Lead Dealer Manager, in each case at the telephone numbers and addresses set forth on the back cover of this Offer to Purchase. You may request additional copies of the Offer to Purchase and other Offer documents from the Information Agent at the telephone number and address on the back cover of the Offer to Purchase.

IMPORTANT

          If you wish to tender all or any part of your Shares, you must do one of the following before the Offer expires at 5:00 p.m., New York City time, on Monday, November 14, 2005 or any later time to which the Offer may be extended:

• If you hold certificates in your own name, follow the instructions described in Section 3 carefully, including completing a Letter of Transmittal in accordance with the instructions and delivering it, along with the certificates evidencing your Shares and any other documents required by the Letter of Transmittal, to National City Bank, the Depositary;

• If your Shares are registered in the name of a broker, dealer, commercial bank, trust company or other nominee, contact the nominee and request that the nominee tender the Shares for you;

• If you are an institution participating in The Depository Trust Company, which we refer to as the Book-Entry Transfer Facility, tender your Shares according to the procedure for book-entry transfer described in Section 3;

• If you are a participant in the Amended and Restated HCA Employee Stock Purchase Plan wishing to tender any of your Shares held in the plan, you must follow the separate instructions and procedures described in Section 3, by returning the Instruction Form in the “Letter to Participants in the Amended and Restated HCA Employee Stock Purchase Plan” to Computershare Trust Co., Inc., the administrator of the plan (the “ESPP Plan Administrator”), at least three business days prior to the Expiration Date of the Offer (as defined in the Introduction). If the ESPP Plan Administrator has not received a participant’s instructions at least three business days prior to the expiration date of the Offer (which, unless the Offer is extended, will require you to return the Instruction Form no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005), the ESPP Plan Administrator will not tender any Shares held on behalf of that participant; or

• If you are a participant in the HCA 401(k) Plan wishing to tender any of your equivalent Shares held in the plan, you must follow the separate instructions and procedures described in Section 3, by returning the Instruction Form in the “Letter to Participants in the HCA 401(k) Plan” to U.S. Trust Company, N.A., the independent fiduciary of the 401(k) Plan (“U.S. Trust”), at least three business days prior to the Expiration Date of the Offer (as defined in the Introduction). If U.S. Trust has not received a participant’s instructions at least three business days prior to the expiration date of the Offer (which, unless the Offer is extended, will require you to return the Instruction Form no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005), U.S. Trust will not tender any equivalent Shares held on behalf of that participant. Your equivalent Shares are equal to the total market value of your HCA Stock Fund account in your HCA 401(k) Plan divided by the closing market price per share of our common stock on a particular day.

          Any shareholder who desires to tender Shares and whose certificates for the Shares are not immediately available or cannot be delivered to the Depositary or who cannot comply with the procedure for book-entry transfer or whose other required documents cannot be delivered to the Depositary prior to the expiration of the Offer must tender the Shares pursuant to the guaranteed delivery procedure set forth in Section 3.

          TO PROPERLY TENDER SHARES, OTHER THAN SHARES YOU HOLD IN THE AMENDED AND RESTATED HCA EMPLOYEE STOCK PURCHASE PLAN OR THE HCA 401(K) PLAN, YOU MUST VALIDLY COMPLETE THE LETTER OF TRANSMITTAL, INCLUDING THE SECTION RELATING TO THE PRICE AT WHICH YOU ARE TENDERING SHARES.

i

          If you wish to maximize the chance that your Shares will be purchased at the Purchase Price determined by us, you should check the box in the section on the Letter of Transmittal captioned “Shares Tendered at Price Determined Pursuant to the Offer.” Note that this election could have the effect of decreasing the purchase price determined by us which may result in your Shares being purchased at the minimum price of $43.00 per Share.

          We are not making the Offer to, and will not accept any tendered Shares from, shareholders in any jurisdiction where it would be illegal to do so. However, we may, at our discretion, take any actions necessary for us to make the Offer to shareholders in any such jurisdiction.

          WE HAVE NOT AUTHORIZED ANY PERSON TO MAKE ANY RECOMMENDATION ON OUR BEHALF AS TO WHETHER YOU SHOULD TENDER OR REFRAIN FROM TENDERING YOUR SHARES OR AS TO THE PURCHASE PRICE AT WHICH YOU MAY CHOOSE TO TENDER YOUR SHARES IN THE OFFER. YOU SHOULD RELY ONLY ON THE INFORMATION CONTAINED IN THIS OFFER TO PURCHASE AND IN THE RELATED LETTER OF TRANSMITTAL OR TO WHICH WE HAVE REFERRED YOU. WE HAVE NOT AUTHORIZED ANYONE TO PROVIDE YOU WITH INFORMATION OR TO MAKE ANY REPRESENTATION IN CONNECTION WITH THE OFFER OTHER THAN THOSE CONTAINED IN THIS OFFER TO PURCHASE OR IN THE RELATED LETTER OF TRANSMITTAL. IF ANYONE MAKES ANY RECOMMENDATION OR GIVES ANY INFORMATION OR REPRESENTATION, YOU MUST NOT RELY UPON THAT RECOMMENDATION, INFORMATION OR REPRESENTATION AS HAVING BEEN AUTHORIZED BY US, THE LEAD DEALER MANAGER OR THE DEALER MANAGER.

SUMMARY TERM SHEET

          We are providing this summary of the terms of the Offer for your convenience. It highlights material information in this Offer to Purchase, but you should realize that it does not describe all of the details of the Offer to the same extent described in this Offer to Purchase. We urge you to read the entire Offer to Purchase and the related Letter of Transmittal because they contain the full details of the Offer. Where helpful, we have included references to the sections of this Offer to Purchase where you will find a more complete discussion.

Who is offering to purchase Shares?

          HCA Inc.

What is the purpose of the Offer?

          Our Board of Directors has reviewed a variety of alternatives for using the Company’s available financial resources with the assistance of management and outside advisors. The Board considered the Company’s capital structure, free cash flow, financial position and dividend policy, the market price of the common stock and the anticipated cost and availability of financing, as well as the Company’s operations, strategy and expectations for the future. The Board believes that increasing the Company’s indebtedness to fund the Offer is a prudent use of the Company’s financial resources and an effective means of providing value to the Company’s shareholders. See Section 2.

What will the purchase price for the Shares be and what will be the form of payment?

          We are conducting the Offer through a procedure commonly called a modified “Dutch” auction. This procedure allows you to select the price within a price range specified by us at which you are willing to sell your Shares. The price range for the Offer is $43.00 to $50.00 per Share. We will select the lowest purchase price (the “Purchase Price”) that will allow us to buy 50,000,000 Shares or, if a lesser number of Shares are properly tendered, all Shares that are properly tendered and not properly withdrawn. For purposes of determining the Purchase Price, those Shares that are tendered by shareholders agreeing to accept the Purchase Price determined in the Offer below will be deemed to be tendered at the minimum price of $43.00. All Shares that we purchase will be purchased at the same price, even if you have selected a lower price, but we will not purchase any Shares above the purchase price we determine. If you wish to maximize the chance that your Shares will be purchased, you should check the box in the section on the Letter of Transmittal indicating that you will accept the purchase price we determine. You should understand that this election could have the effect of decreasing the purchase price determined by us which may result in your Shares being purchased at the minimum price of $43.00 per Share. If your Shares are purchased in the Offer, you will be paid the Purchase Price, in cash, without interest, promptly after the expiration of the Offer (as defined in the Introduction). Under no circumstances will we pay interest on the Purchase Price, even if there is a delay in making payment. See “Introduction” and Section 1.

How many Shares will be purchased?

          We will purchase 50,000,000 Shares in the Offer, or such lesser number of Shares as are properly tendered. The 50,000,000 Shares represent approximately 11.0% of our outstanding common stock as of September 30, 2005. If more than 50,000,000 Shares are properly tendered, all Shares tendered at or below the Purchase Price will be purchased on a pro rata basis, except for “odd lots” (lots held by beneficial owners of less than 100 Shares, but not including any Shares held in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan), which will be purchased on a priority basis. We also expressly reserve the right to purchase additional Shares in an amount equal to up to 2% of the outstanding Shares, and could decide to purchase more Shares, subject to applicable legal requirements. The Offer is not conditioned on any minimum number of Shares being tendered by shareholders. See Section 1.

1

How will HCA pay for the Shares?

          We will need a maximum of approximately $2,500,000,000 to purchase 50,000,000 Shares, assuming the price paid per Share is $50.00. We anticipate that we will obtain the funds necessary to purchase Shares tendered in the Offer by utilizing approximately $500 million of cash on hand, by borrowing approximately $1 billion under our revolving credit facility, as proposed to be amended, or pursuant to the terms and conditions contained in the Refinancing Commitment Letter (as defined in Section 9), and by borrowing approximately $1 billion pursuant to the terms and conditions of the Term Facility Commitment Letter (as defined in Section 9). At the time of the Offer, except as otherwise described herein, the Company does not have any alternative financing arrangements or plans in the event these sources do not provide the funds necessary to fund the Offer. See Section 9.

Can the Offer be extended, amended or terminated and, if so, under what circumstances?

          We can extend or amend the Offer in our sole discretion. If we extend the Offer, we will delay the acceptance of any Shares that have been tendered. See Section 15 for a more detailed discussion of the extension and amendment of the Offer. We can also terminate the Offer under certain circumstances. See Section 7.

How will I be notified if the Offer is extended or amended?

          If the Offer is extended, we will make a public announcement of the extension no later than 9:00 a.m., New York City time, on the first business day after the previously scheduled Expiration Date (as that term is defined in the Introduction). We will announce any amendment to the Offer by making a public announcement of the amendment. See Section 15.

How long do I have to tender my Shares?

          Unless you are a participant in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan, you may tender your Shares until the Offer expires. If you are a participant in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan, you may deliver instructions regarding your Shares to the applicable plan administrator at any time until three business days prior to the expiration of the Offer. The Offer will expire on Monday, November 14, 2005, at 5:00 p.m., New York City time, unless we extend the Offer. Therefore, unless the Offer is extended, participants in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan will be required to return the Instruction Form no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005. We may choose to extend the Offer at any time. We cannot assure you, however, that we will extend the Offer or, if we extend it, for how long. See “Introduction” and Sections 1 and 15.

Are there any conditions to the Offer?

          Yes. Our obligation to accept and pay for your tendered Shares depends upon a number of conditions, including:

• Amending our existing credit facility or refinancing it pursuant to the terms and conditions contained in the Refinancing Commitment Letter;

• Obtaining financing pursuant to the terms and conditions contained in the Term Facility Commitment Letter;

• No significant decrease in the price of our common stock, or in the price of equity securities generally, and no significant adverse changes in the U.S. stock markets or credit markets, shall have occurred during the Offer;

• No legal action shall be pending, or shall have been threatened or taken, that might adversely affect the Offer;

2

• No one shall have proposed, announced or made a tender or exchange offer (other than the Offer), merger, business combination or other similar transaction involving us;

• No material change in our business, condition (financial or otherwise), assets, income, operations, prospects or stock ownership shall have occurred during the Offer; and

• No one (including a group) shall have acquired, or proposed to acquire, beneficial ownership of more than 5% of the outstanding Shares (other than anyone who publicly disclosed such ownership in a filing with the Securities and Exchange Commission (the “SEC”) on or before October 12, 2005). In addition, no new group shall have been formed which beneficially owns more than 5% of the outstanding Shares. Finally, no one shall have filed a Notification and Report Form under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, or made a public announcement reflecting an intent to acquire us or any of our subsidiaries or any of our respective assets or securities, other than in connection with a transaction authorized by our Board of Directors.

          For more information on conditions to the Offer, see Sections 7 and 9.

Following the Offer, will HCA Inc. continue as a public company?

          We do not believe the completion of the Offer in accordance with its conditions will cause HCA to be delisted from the New York Stock Exchange (the “NYSE”) or to stop being subject to the periodic reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). See Section 2.

How do I tender my Shares?

          To tender your Shares, prior to 5:00 p.m., New York City time, on Monday, November 14, 2005, unless the Offer is extended:

• You must deliver the certificate(s) evidencing your Shares and a properly completed and duly executed Letter of Transmittal to the Depositary at the address appearing on the back cover of this Offer to Purchase; or

• The Depositary must receive a confirmation of receipt of your Shares by book-entry transfer and a properly completed and duly executed Letter of Transmittal or an Agent’s Message, in the case of a book-entry transfer; or

• The Depositary must receive a confirmation of receipt of your Shares through the Automated Tender Offer Program and specific acknowledgement that you agree to the terms of, and to be bound by, the Letter of Transmittal; or

• You must comply with the guaranteed delivery procedure outlined in Section 3.

          You may contact the Information Agent, the Lead Dealer Manager or your broker for assistance. The contact information for the Information Agent and Lead Dealer Manager are set forth on the back cover of this Offer to Purchase. See Section 3 and the instructions to the Letter of Transmittal.

          If you are a participant in the Amended and Restated HCA Employee Stock Purchase Plan and you wish to tender any of your Shares held in the plan, you must follow the separate instructions and procedures described in Section 3 by returning the Instruction Form in the “Letter to Participants in the Amended and Restated HCA Employee Stock Purchase Plan” to the ESPP Plan Administrator at least three business days prior to the Expiration Date (as that term is defined in the Introduction) (which, unless the Offer is extended, will require you to return the Instruction Form no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005). If the ESPP Plan Administrator has not received a participant’s instructions at least three business days prior to the Expiration Date, the ESPP Plan Administrator will not tender any Shares held on behalf of that participant.

3

          If you are a participant in the HCA 401(k) Plan and you wish to tender any of your equivalent Shares held in the plan, you must follow the separate instructions and procedures described in Section 3 by returning the Instruction Form in the “Letter to Participants in the HCA 401(k) Plan” to U.S. Trust at least three business days prior to the Expiration Date (as that term is defined in the Introduction) (which, unless the Offer is extended, will require you to return the Instruction Form no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005). If U.S. Trust has not received a participant’s instructions at least three business days prior to the Expiration Date, U.S. Trust will not tender any equivalent Shares held on behalf of that participant. Your equivalent Shares are equal to the total market value of your HCA Stock Fund account in the plan divided by the closing market price per share of our common stock on a particular day. Our 401(k) Plan is prohibited from selling equivalent Shares to us for a price that is less than the prevailing market price of our common stock. Accordingly, if a participant elects to tender equivalent Shares at a price that is lower than the closing price of our common stock on the date the Offer expires, the tender price a participant elects will be deemed to have been increased to the closest tender price that is not less than the closing price of our common stock on the NYSE on the date the Offer expires. This could result in a participant’s equivalent Shares not being purchased in the Offer. If the closing price of our common stock on the date the Offer expires is greater than the maximum price available in the Offer, none of the equivalent Shares will be tendered and a participant’s tender will be deemed to have been withdrawn.

Once I have tendered Shares in the Offer, can I withdraw my tendered Shares?

          Yes. You may withdraw your tendered Shares at any time before 5:00 p.m., New York City time, on Monday, November 14, 2005, unless we extend the Offer, in which case you can withdraw your Shares until the expiration of the Offer as extended. Notwithstanding the foregoing, if you are a participant in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan, your notice of withdrawal must be received by the applicable plan administrator at least three business days before the Expiration Date in accordance with the instructions set forth in the letters sent separately to the participants in such plans. If we have not accepted for payment the Shares you have tendered to us, you may also withdraw your Shares at any time after 5:00 p.m., New York City time, on December 13, 2005. See Section 4.

How do I withdraw Shares I previously tendered?

          You must deliver on a timely basis a written or facsimile notice of your withdrawal to the Depositary at the address appearing on the back cover of this Offer to Purchase. Your notice of withdrawal must specify your name, the number of Shares to be withdrawn and the name of the registered holder of the Shares. Some additional requirements apply if the certificates evidencing the Shares to be withdrawn have been delivered to the Depositary or if your Shares have been tendered under the procedure for book-entry transfer set forth in Section 3. Participants in the Amended and Restated HCA Employee Stock Purchase Plan who wish to withdraw their Shares must follow the instructions found in the “Letter to Participants in the Amended and Restated HCA Employee Stock Purchase Plan” sent to them separately. Participants in the HCA 401(k) Plan who wish to withdraw their Shares must follow the instructions found in the “Letter to Participants in the HCA 401(k) Plan” sent to them separately. See Section 4.

In what order will tendered Shares be purchased?

          First, we will purchase Shares from all holders of “odd lots” of less than 100 Shares (not including any Shares held in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan) who properly tender all of their Shares at or below the Purchase Price selected by us. Second, after purchasing all Shares from the “odd lot” holders, we will purchase Shares from all other shareholders (including participants in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan) who properly tender Shares at or below the Purchase Price selected by us, on a pro rata basis, subject to the conditional tender provisions described in Section 6. Third, if necessary to

4

permit us to purchase 50,000,000 Shares (or such greater number of Shares as we elect to purchase in accordance with applicable SEC rules), Shares conditionally tendered (for which the condition was not initially satisfied) at or below the Purchase Price selected by us will be selected for purchase by random lot, to the extent feasible. To be eligible for purchase by random lot, shareholders whose Shares are conditionally tendered must have tendered all of their Shares. Therefore, all of the Shares that you tender in the Offer may not be purchased even if they are tendered at or below the Purchase Price selected by us. See Section 1.

Can I tender Shares in the Offer subject to the condition that a specified minimum number of Shares must be purchased?

          Yes, you may tender your Shares subject to this condition by following the procedures described in Section 6.

What do HCA and its Board of Directors think of the Offer?

          Our Board of Directors has approved the Offer. However, neither we nor our Board of Directors, the Lead Dealer Manager, the Dealer Manager, Information Agent or Depositary are making any recommendation as to whether you should tender or refrain from tendering your Shares or at what price you should tender your Shares. You must decide whether to tender your Shares and, if so, how many Shares to tender and the price or prices at which you will tender them. In doing so, you should read carefully the information in this Offer to Purchase and in the related Letter of Transmittal, including the purposes and effects of the Offer. You should discuss whether to tender your Shares with your broker, if any, or other financial advisor. See Section 2.

If I decide not to tender, how will the Offer affect my Shares?

          Shareholders who choose not to tender will own a greater percentage interest in the Company following the consummation of the Offer. See Section 2.

Will HCA’s directors and executive officers tender Shares in the Offer?

          Our directors and executive officers have advised us that they do not intend to tender Shares pursuant to the Offer. See Section 12.

When and how will HCA pay me for the Shares I tender?

          We will pay the Purchase Price, in cash, without interest, for the Shares we purchase promptly after the expiration of the Offer. We will pay for the Shares accepted for purchase by depositing the aggregate purchase price with the Depositary promptly after the Expiration Date (as defined in the Introduction) of the Offer. The Depositary will act as your agent and will transmit to you the payment for all of your Shares accepted for payment. See Sections 1 and 5.

What is the recent market price of the Shares?

          On October 12, 2005, the last full trading day before the announcement of the Offer, the last reported price per Share on the NYSE was $46.69. You are urged to obtain current market quotations for your Shares prior to making your decision whether or not to tender pursuant to the Offer. See Section 8.

Will I have to pay brokerage commissions if I tender my Shares?

          If you are a registered shareholder and you tender your Shares directly to the Depositary, you will not incur any brokerage commission. If you hold Shares through a broker, dealer, commercial bank, trust company or other nominee, we urge you to consult your nominee to determine whether any transaction costs may apply. See the Introduction and Section 3.

5

What are the U.S. federal income tax consequences if I tender my Shares?

          Generally, you will be subject to U.S. federal income taxation when you receive cash from us in exchange for the Shares you tender. Your receipt of cash for your tendered Shares will generally be treated as either (1) consideration received in a sale or exchange or (2) a dividend. See Section 14.

Will I have to pay stock transfer tax if I tender my Shares?

          If you instruct the Depositary in the related Letter of Transmittal to make the payment for the Shares to the registered holder, you will not incur any stock transfer tax. See Section 5.

Does the Company intend to repurchase any Shares other than pursuant to the Offer during or after the Offer?

          In connection with its approval of the Offer, our Board of Directors expressly authorized us to acquire, in open market or other repurchase transactions, such additional number of Shares, if any, as is necessary to enable us to repurchase an aggregate of up to $2,500,000,000 in Shares (including the aggregate purchase price paid for the Shares acquired pursuant to the Offer). However, Rule 13e-4(f) under the Exchange Act prohibits us from purchasing any Shares, other than in the Offer, until at least 10 business days after the Expiration Date.

INTRODUCTION

To the Holders of our Common Stock:

          HCA Inc., a Delaware corporation, invites our shareholders to tender shares of our common stock, $0.01 par value per share, for purchase by us. We are offering to purchase up to 50,000,000 Shares at a price not greater than $50.00 nor less than $43.00 per Share, net to the seller in cash less any applicable withholding taxes, without interest.

          We will select the lowest purchase price (the “Purchase Price”) that will allow us to buy 50,000,000 Shares or, if a lesser number of Shares is properly tendered, all Shares that are properly tendered and not properly withdrawn. All Shares acquired in the Offer will be acquired at the same price.

          The Offer is being made upon the terms and subject to the conditions set forth in this Offer to Purchase and in the related Letter of Transmittal, which together, as they may be amended or supplemented from time to time, constitute the Offer. This Offer to Purchase and the related Letter of Transmittal contain important information that should be read carefully before any decision is made with respect to the Offer.

          The Offer will expire at 5:00 p.m., New York City time, on Monday, November 14, 2005, unless extended (such date and time, as the same may be extended, the “Expiration Date”). We may, in our sole discretion, extend the period of time in which the Offer will remain open.

          Only Shares properly tendered at prices at or below the Purchase Price we select and not properly withdrawn will be purchased. However, because of the “odd lot” priority, proration and conditional tender provisions described in this Offer to Purchase, all of the Shares tendered at or below the Purchase Price selected by us will not be purchased if more than the number of Shares we seek are tendered. We will return any Shares tendered at prices in excess of the Purchase Price that we select and Shares we do not purchase because of proration or conditional tenders promptly following the Expiration Date. See Section 3.

          We reserve the right, in our sole discretion, to purchase more than 50,000,000 Shares pursuant to the Offer, subject to certain limitations and legal requirements. See Sections 1 and 15.

          The Offer is not conditioned on any minimum number of Shares being tendered. However, the Offer is subject to other conditions, including amending our existing credit facility or refinancing it pursuant to the terms and conditions contained in the Refinancing Commitment Letter and obtaining the necessary financing for the Offer pursuant to the terms and conditions contained in the Term Facility Commitment Letter. See Sections 7 and 9.

          OUR BOARD OF DIRECTORS HAS APPROVED THE OFFER. HOWEVER, NEITHER WE NOR OUR BOARD OF DIRECTORS, THE LEAD DEALER MANAGER, THE DEALER MANAGER, THE INFORMATION AGENT OR THE DEPOSITARY ARE MAKING ANY RECOMMENDATION TO YOU AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING YOUR SHARES OR AS TO THE PRICE AT WHICH YOU MAY CHOOSE TO TENDER YOUR SHARES. YOU MUST MAKE YOUR OWN DECISION AS TO WHETHER TO TENDER YOUR SHARES AND, IF SO, HOW MANY SHARES TO TENDER AND THE PRICE OR PRICES AT WHICH YOU WILL TENDER THEM. IN DOING SO, YOU SHOULD READ CAREFULLY THE INFORMATION IN THIS OFFER TO PURCHASE AND IN THE RELATED LETTER OF TRANSMITTAL, INCLUDING THE PURPOSES AND EFFECTS OF THE OFFER. SEE SECTION 2. YOU SHOULD DISCUSS WHETHER TO TENDER YOUR SHARES WITH YOUR BROKER, IF ANY, OR OTHER FINANCIAL ADVISOR.

          OUR DIRECTORS AND EXECUTIVE OFFICERS HAVE ADVISED US THAT THEY DO NOT INTEND TO TENDER SHARES PURSUANT TO THE OFFER. SEE SECTION 12.

9

          If, at the Expiration Date, more than 50,000,000 Shares (or such greater number of Shares as we may elect to purchase) are properly tendered at or below the Purchase Price and not properly withdrawn, we will buy Shares:

• First, from all Odd Lot Holders (as defined in Section 1), which excludes any Shares held in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan, who properly tender all of their Shares at or below the Purchase Price;

• Second, on a pro rata basis from all other shareholders (including participants in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan) who properly tender their Shares at or below the Purchase Price, other than shareholders who tender conditionally at or below the Purchase Price and whose conditions are not initially satisfied; and

• Third, by random lot, from shareholders who have tendered their Shares conditionally (for which the condition was not initially satisfied) at or below the Purchase Price.

          See Sections 1 and 6 for additional information concerning priorities and proration procedures.

          The Purchase Price will be paid net to the tendering shareholder in cash less any applicable withholding taxes, without interest, for all Shares purchased. Tendering shareholders who hold Shares registered in their own name and who tender their Shares directly to the Depositary will not be obligated to pay brokerage commissions, solicitation fees or, subject to Instruction 8 of the Letter of Transmittal, stock transfer taxes on our purchase of Shares in the Offer. Shareholders holding Shares through brokers, dealers, commercial banks, trust companies or other nominees are urged to consult such nominees to determine whether any transaction costs may apply. Any tendering shareholder or other payee who fails to complete, sign and return to the Depositary the Substitute Form W-9 that is included as part of the Letter of Transmittal or U.S. Internal Revenue Service (“IRS”) Form W-8BEN obtained from the Depositary, whichever is applicable, may be subject to required United States federal income tax backup withholding equal to 28% of the gross proceeds payable to the tendering shareholder or other payee pursuant to the Offer. See Section 3. Also see Section 3 for other United States federal income tax withholding considerations relevant to tendering Non-United States Holders.

          Participants in the Amended and Restated HCA Employee Stock Purchase Plan may tender any of their Shares held in the plan by following the separate instructions and procedures described in Section 3 and by returning the Instruction Form in the “Letter to Participants in the Amended and Restated HCA Employee Stock Purchase Plan” to the ESPP Plan Administrator at least three business days prior to the Expiration Date (which, unless the Offer is extended, will require you to return the Instruction Form no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005). If the ESPP Plan Administrator has not received a participant’s instructions at least three business days prior to the expiration date of the Offer, the ESPP Plan Administrator will not tender any Shares held on behalf of that participant.

          Participants in the HCA 401(k) Plan may tender any of their equivalent Shares held in the plan by following the separate instructions and procedures described in Section 3 and by returning the Instruction Form in the “Letter to Participants in the HCA 401(k) Plan” to U.S. Trust at least three business days prior to the Expiration Date (which, unless the Offer is extended, will require you to return the Instruction Form no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005). If U.S. Trust has not received a participant’s instructions at least three business days prior to the expiration date of the Offer, U.S. Trust will not tender any equivalent Shares held on behalf of that participant. Your equivalent Shares are equal to the total market value of your HCA Stock Fund account in the plan divided by the closing market price per share of our common stock on a particular day.

          As of September 30, 2005, we had 452,666,600 issued and outstanding Shares, and 27,820,700 Shares reserved for issuance upon exercise of outstanding stock options under our stock option plans. The 50,000,000 Shares that we are offering to purchase pursuant to the Offer represent approximately 11.0% of our Shares outstanding as of September 30, 2005. The Shares are listed and traded on the NYSE under the symbol “HCA.” On October 12, 2005, the last full trading day before the announcement of the Offer, the last reported sale price of the Shares was $46.69 per Share. Shareholders are urged to obtain current market quotations for the Shares prior to making your decision whether or not to tender pursuant to the Offer. See Section 8.

THE OFFER

1. Terms Of The Offer

          Upon the terms and subject to the conditions of the Offer, we will purchase 50,000,000 Shares or, if a lesser number of Shares is properly tendered, all Shares that are properly tendered and not properly withdrawn in accordance with Section 4 on or before the Expiration Date, at prices not greater than $50.00 nor less than $43.00 per Share, net to the seller in cash less any applicable withholding taxes, without interest.

          In accordance with Instruction 5 of the Letter of Transmittal, shareholders desiring to tender Shares must either (1) specify that they are willing to sell their Shares to us at the price determined in the Offer, or (2) specify the price, not greater than $50.00 nor less than $43.00 per Share (in multiples of $0.25), at which they are willing to sell their Shares to us in the Offer. Promptly following the Expiration Date, we will, upon the terms and subject to the conditions of the Offer, determine a single per Share purchase price that we will pay for Shares properly tendered and not properly withdrawn pursuant to the Offer, taking into account the number of Shares tendered and the prices. We will select the lowest purchase price specified by shareholders (the “Purchase Price”) that will allow us to buy 50,000,000 Shares or, if a lesser number of Shares is properly tendered, all Shares that are properly tendered and not properly withdrawn. All Shares purchased in the Offer will be purchased at the same Purchase Price.

          Only Shares properly tendered at prices at or below the Purchase Price and not properly withdrawn will be purchased. However, because of the “odd lot” priority, proration and conditional tender provisions of the Offer, all of the Shares tendered at or below the Purchase Price will not be purchased if more than the number of Shares we seek are properly tendered. All Shares tendered and not purchased in the Offer, including Shares tendered at prices in excess of the Purchase Price and Shares not purchased because of proration or conditional tenders, will be returned to the tendering shareholders at our expense promptly following the Expiration Date.

          We reserve the right to purchase more than 50,000,000 Shares in the Offer, subject to certain limitations and legal requirements. In accordance with applicable regulations of the SEC, we may purchase in the Offer an additional number of Shares not to exceed 2% of the currently outstanding Shares (approximately 9,053,332 Shares) without amending or extending the Offer. See Section 15.

          In the event of an oversubscription of the Offer, Shares tendered at or below the Purchase Price on or before the Expiration Date will be subject to proration, except for Odd Lots (as defined below). The proration period also expires on the Expiration Date.

          If we (1) increase the price that may be paid for Shares above $50.00 per Share or decrease the price that may be paid for Shares below $43.00 per Share, (2) materially increase the Lead Dealer Manager’s fee, (3) increase the number of Shares that we may purchase in the Offer by more than 2% of our outstanding Shares or (4) decrease the number of Shares that we may purchase in the Offer, then the Offer must remain open for at least 10 business days following the date that notice of the increase or decrease is first published, sent or given in the manner specified in Section 15.

          The Offer is not conditioned on any minimum number of Shares being tendered. However, the Offer is subject to other conditions, including amending our existing credit facility or refinancing it pursuant to the terms and conditions contained in the Refinancing Commitment Letter and obtaining the necessary financing for the Offer pursuant to the terms and conditions contained in the Term Facility Commitment Letter. See Sections 7 and 9.

          Priority of Purchases. If more than 50,000,000 Shares (or such greater number of Shares as we may elect to purchase) have been properly tendered at prices at or below the Purchase Price selected by

11

us and not properly withdrawn on or before the Expiration Date, we will purchase properly tendered Shares on the basis set forth below:

• First, we will purchase all Shares tendered by any Odd Lot Holder (as defined below), which excludes any Shares held in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan, who:

                  (1) tenders all Shares owned beneficially or of record by the Odd Lot Holder at a price at or below the Purchase Price selected by us (tenders of less than all of the Shares owned by the Odd Lot Holder will not qualify for this preference); and

                  (2) completes the section entitled “Odd Lots” in the Letter of Transmittal and, if applicable, in the Notice of Guaranteed Delivery;

• Second, after the purchase of all of the Shares properly tendered by Odd Lot Holders, subject to the conditional tender provisions described in Section 6, we will purchase all other Shares tendered (including participants in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan) at prices at or below the Purchase Price on a pro rata basis, with appropriate adjustments to avoid purchases of fractional Shares, based on the ratio of the remaining number of Shares to be purchased by us in the Offer to the number of all Shares tendered (other than those tendered by Odd Lot Holders which are given priority as described above). This ratio will be applied to shareholders tendering their Shares to determine the number of Shares that will be purchased from each tendering shareholder in the Offer; and

• Third, if necessary to permit us to purchase 50,000,000 Shares, Shares conditionally tendered (for which the condition was not initially satisfied) at or below the Purchase Price selected by us and not properly withdrawn prior to the Expiration Date, will, to the extent feasible, be selected for purchase by random lot. To be eligible for purchase by random lot, shareholders whose Shares are conditionally tendered must have tendered all of their Shares.

          As a result of the foregoing priorities applicable to the purchase of Shares tendered, it is possible that fewer than all of the Shares tendered by a shareholder will be purchased or that, if a tender is conditioned upon the purchase of a specified number of Shares from the tendering shareholder, none of those Shares will be purchased even though those Shares were tendered at prices at or below the Purchase Price.

          Odd Lots. The term “Odd Lots” means all Shares (other than Shares held in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan) that are tendered by shareholders at prices at or below the Purchase Price selected by us (an “Odd Lot Holder”) who own beneficially or of record an aggregate of fewer than 100 Shares and so certify in the appropriate place on the Letter of Transmittal and, if applicable, on the Notice of Guaranteed Delivery. To qualify for this preference, an Odd Lot Holder must tender all Shares owned by the Odd Lot Holder in accordance with the procedures described in Section 3. Odd Lots will be accepted for payment before any proration of the purchase of other tendered Shares. This preference is not available to partial tenders or to beneficial or record holders of an aggregate of 100 or more Shares, even if these holders have separate accounts or certificates representing fewer than 100 Shares, or with respect to any Shares held in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan. By tendering in the Offer, an Odd Lot Holder which holds Shares in its name and tenders its Shares directly to the Depositary would not only avoid the payment of brokerage commissions, but also would avoid any applicable odd lot discounts in a sale of the holder’s Shares. Any Odd Lot Holder wishing to tender all of its Shares in the Offer should complete the section entitled “Odd Lots” in the Letter of Transmittal and, if applicable, in the Notice of Guaranteed Delivery.

          We also reserve the right, but will not be obligated, to purchase all Shares properly tendered by any shareholder who tenders any Shares owned beneficially or of record, at or below the Purchase Price and who, as a result of proration, would then own beneficially or of record, an aggregate of fewer than 100 Shares. If we exercise this right, we will increase the number of Shares that we are offering to

12

purchase in the Offer by the number of Shares purchased through the exercise of the right, and to the extent required by applicable law, extend the Offer.

          Proration. If proration of tendered Shares is required, we will determine the Proration Factor promptly following the Expiration Date. The “Proration Factor” shall be equal to the ratio of the remaining number of Shares to be purchased by us in the Offer to the number of Shares tendered by all shareholders (including participants in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan), other than Odd Lot Holders, at or below the Purchase Price selected by us. Proration will also be subject to the procedures described above under “Priority of Purchases.” Because of the difficulty in determining the number of Shares properly tendered and not properly withdrawn, and because of the Odd Lot procedure described above and the conditional tender procedure described in Section 6, we do not expect that we will be able to announce the final Proration Factor or commence payment for any Shares purchased pursuant to the Offer until approximately seven business days after the Expiration Date. The preliminary results of any proration will be announced by press release promptly after the Expiration Date. After the Expiration Date, shareholders may obtain preliminary proration information from the Information Agent and also may be able to obtain the information from their brokers.

          As described in Section 14, the number of Shares that we will purchase from a shareholder in the Offer may affect the U.S. federal income tax consequences of the purchase to the shareholder and, therefore, may be relevant to a shareholder’s decision whether to tender Shares and whether to condition any tender upon our purchase of a stated number of Shares held by such shareholder. The Letter of Transmittal affords each tendering shareholder the opportunity to designate the order of priority in which Shares tendered are to be purchased in the event of proration.

          This Offer to Purchase and the related Letter of Transmittal will be mailed to record holders of the Shares and will be furnished to brokers, dealers, commercial banks, trust companies and other nominees whose names, or the names of whose nominees, appear on our shareholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing for subsequent transmittal to beneficial owners of Shares.

2. Purpose Of The Offer; Certain Effects Of The Offer

          Purpose of the Offer. HCA intends to purchase up to 50,000,000 shares of its common stock in the Offer, representing approximately 11.0% of its outstanding shares as of September 30, 2005. In determining to proceed with the Offer, the Board of Directors has reviewed, with the assistance of management and outside advisors, its strategic plan, its use of cash flows from operations for, among other things, capital expenditures, acquisitions, debt repayment, dividends and share repurchases, and a variety of alternatives for using the Company’s available financial resources. The Board of Directors considered, with the assistance of management and outside advisors, the Company’s capital structure, free cash flow, financial position and dividend policy, the anticipated cost and availability of financing and the market price of the common stock, as well as the Company’s operations, strategy and expectations for the future.

          In determining the number of Shares to purchase in the Offer, the Board of Directors considered a broad range of factors, including our financial structure, financial condition and dividend policy, operations, competitive position, resources and prospects, the current market prices of our Shares, our desire for future financial flexibility, the expected availability and cost of financing, and the attractiveness of the Offer to our shareholders. The Board of Directors also considered risks and uncertainties, including the potential for positive and negative developments relating to our business.

          Based on the foregoing, the Board of Directors has determined that increasing the Company’s indebtedness to fund the Offer is a prudent use of the Company’s financial resources and an effective means of providing value to the Company’s shareholders. In particular, the Board of Directors believes the Offer will provide all shareholders with the opportunity to tender all or a portion of their Shares and, thereby, receive a return of capital if they so elect. Conversely, the Offer also affords shareholders the option not to participate and, thereby, to increase their relative percentage interest in the Company and our future results. In addition, the Board of Directors believes the Offer provides shareholders (particularly those who, because of the size of their stockholdings, might not be able to sell their Shares without

13

potential disruption to the Share price) with an opportunity to obtain liquidity with respect to all or a portion of their Shares, without potential disruption to the Share price and the usual transaction costs associated with market sales.

          Our Board of Directors has approved the Offer. However, neither we nor our Board of Directors, the Lead Dealer Manager, the Dealer Manager, the Information Agent or the Depositary are making any recommendation to shareholders as to whether to tender or refrain from tendering their Shares or as to the price at which shareholders should tender their Shares, and none of them have authorized any person to make any recommendation. Shareholders are urged to evaluate carefully all information in the Offer, consult with their own investment and tax advisors and make their own decision whether to tender and, if so, how many Shares to tender and the price or prices at which to tender them. We have been advised that our directors and executive officers do not intend to tender their Shares pursuant to the Offer. See Section 12.

          Potential Benefits of the Offer. The Company believes the Offer may provide several benefits to the Company and its shareholders, including:

• The Offer and related anticipated borrowings will provide a capital structure that makes greater use of financial leverage at expected interest rates, thus making possible improved earnings per share for our continuing shareholders;

• Capitalizing on pricing in the current bank, public and/or private debt markets that we believe to be attractive;

• After the Offer is completed, the Company believes that its anticipated financial condition, access to capital and cash flow from operations will allow the Company adequate financial resources to fund future dividends and capital expenditures; and

• If we complete the Offer, we will return cash to our shareholders who elect to receive a return of capital, while shareholders who do not tender will increase their percentage ownership in the Company.

          Potential Risks and Disadvantages of the Offer. The Offer also presents some potential risks and disadvantages to the Company and its continuing shareholders, including:

• If we complete the Offer, our indebtedness and interest expense would increase significantly;

• By increasing our indebtedness, the Offer could reduce our ability to engage in significant cash acquisitions. Increased indebtedness could reduce our ability to cover existing contingent or other future liabilities or otherwise negatively impact our liquidity during periods of increased capital or operating expenses. There can be no assurance that we would be able to raise debt or equity financing in the future;

• The Offer, if subscribed to in full, will reduce our “public float,” which is the number of Shares owned by non-affiliate shareholders and available for trading in the securities markets. This reduction in our public float could result in a lower stock price and/or reduced liquidity in the trading market for our common stock following completion of the Offer; and

• In addition, if any Shares are accepted in the Offer, the number of outstanding Shares remaining will decrease and effectively give option holders a greater percentage ownership interest in the Company on a fully-diluted basis.

          Certain Effects of the Offer. Upon the completion of the Offer, non-tendering shareholders will own a greater percentage interest in the Company. Assuming that 50,000,000 Shares are purchased in response to the Offer and that our directors and executive officers do not tender any Shares, the relative percentage of Shares beneficially owned by our directors and executive officers in the aggregate will increase from approximately 5.7% to approximately 6.4%. If any of the directors and executive officers ultimately elect to tender Shares in the Offer, their proportional holdings may significantly decrease.

14

          As further described in Section 9 below, we anticipate that we will obtain the funds necessary to purchase Shares tendered in the Offer by utilizing approximately $500 million of cash on hand, by borrowing approximately $1 billion from our existing revolving credit facility and by borrowing approximately $1 billion pursuant to the terms and conditions of the Term Facility Commitment Letter. In connection with the Offer, we are seeking an amendment to our existing credit facility as described below in Section 9. If we are unable to obtain the required amendment prior to the Expiration Date, we expect to refinance our existing revolving credit facility and the related senior term loan facility with a new $2.425 billion facility pursuant to the terms and conditions contained in the Refinancing Commitment Letter (as defined below in Section 9). While we have obtained commitments pursuant to the Term Facility Commitment Letter and the Refinancing Commitment Letter, these commitments are contingent on the satisfaction of various conditions as further described in Section 9 below. Accordingly, as discussed in Section 7 below, in addition to the other conditions described in this Offer to Purchase, the Offer will be subject to our amending our existing credit facility or refinancing it pursuant to the terms and conditions contained in the Refinancing Commitment Letter and obtaining the necessary financing for the Offer pursuant to the terms and conditions contained in the Term Facility Commitment Letter. Our expected plans to repay this indebtedness are also described in Section 9.

          After the Offer is completed, we believe that our expected cash flow from operations, anticipated proceeds from the sale of ten hospitals, and anticipated access to our credit facility and capital markets will be adequate for our expected liquidity needs. However, our actual experience may differ significantly from our expectations and there can be no assurance that our action in utilizing a significant portion of our financial resources in this manner will not adversely affect our ability to operate our business or pursue opportunities we believe are advantageous to the Company and its shareholders. Future events may adversely and materially affect our business, expenses or prospects and could affect our available cash or the availability and/or cost of external financial resources.

          As of June 30, 2005, the net book value per Share of our common stock was $13.53. Assuming that the 50,000,000 Shares sought to be purchased by us had been acquired on such date at a maximum price of $50.00 per Share, the adjusted net book value per Share as of that date would have been $9.00. See Section 10.

          Non-tendering shareholders will realize a proportionate increase in their relative ownership interest in us and thus in our future earnings and assets, subject to our right to issue additional Shares of common stock and other equity securities in the future. Shareholders may be able to sell non-tendered Shares in the future on the NYSE or otherwise at a net price significantly higher than the Purchase Price in the Offer. We can give no assurance, however, as to the price at which a shareholder may be able to sell his or her Shares in the future, which may be higher or lower than the Purchase Price paid by us in the Offer.

          In connection with its approval of the Offer, our Board of Directors expressly authorized us to acquire, in open market or other repurchase transactions, such additional number of Shares, if any, as is necessary to enable us to repurchase an aggregate of up to $2,500,000,000 in Shares (including the aggregate purchase price paid for the Shares acquired pursuant to the Offer). However, Rule 13e-4(f) under the Exchange Act prohibits us from purchasing any Shares, other than in the Offer, until at least 10 business days after the Expiration Date. Accordingly, any such additional repurchases outside of the Offer may not be consummated until at least 10 business days after the Expiration Date. Although we currently have no other plans to do so, we may, in the future, decide to purchase additional Shares. Any such purchases may be on the same terms as, or on terms that are more or less favorable to shareholders than, the terms of the Offer.

          Shares that we acquire in the Offer will be restored to the status of authorized but unissued Shares and will be available for us to issue in the future without further shareholder action (except as required by applicable law or NYSE rules) for all purposes, such as issuance under our stock option plans, the acquisition of other businesses or the raising of additional capital for use in our business. We have no current plans for the issuance of Shares purchased in the Offer.

          Our purchase of Shares in the Offer will reduce the number of Shares that might otherwise trade publicly and is likely to reduce the number of our shareholders. This may reduce the volume of trading in

15

our Shares and make it more difficult to buy or sell significant amounts of our Shares without materially affecting the market price. However, even if all 50,000,000 Shares are purchased in the Offer, more than 400,000,000 Shares will remain outstanding. Based upon published guidelines of the NYSE, we do not believe that our purchase of Shares in the Offer will cause our remaining Shares to be delisted from the NYSE.

          Our Shares are currently “margin securities” under the rules of the Federal Reserve Board. This has the effect, among other things, of allowing brokers to extend credit to their customers using the Shares as collateral. We believe that, following the purchase of Shares pursuant to the Offer, the Shares will continue to be “margin securities” for purposes of the Federal Reserve Board’s margin regulations.

          Our Shares are registered under the Exchange Act, which requires, among other things, that we furnish information to our shareholders and to the SEC and comply with the SEC’s proxy rules in connection with meetings of our shareholders. We believe that our purchase of Shares in the Offer will not result in the Shares becoming eligible for deregistration under the Exchange Act.

3. Procedures For Tendering Shares

          Proper Tender of Shares. For Shares to be tendered properly in the Offer:

• the certificates for the Shares, or confirmation of receipt of the Shares under the procedure for book-entry transfer set forth below, together with (a) a properly completed and duly executed Letter of Transmittal (or a manually signed facsimile of the Letter of Transmittal), including any required signature guarantees, (b) an Agent’s Message (as defined below) in the case of a book-entry transfer or (c) the specific acknowledgement in the case of a tender through the Automated Tender Offer Program (as described below) of the Book-Entry Transfer Facility (as defined below), and any other documents required by the Letter of Transmittal, must be received before 5:00 p.m., New York City time, on the Expiration Date by the Depositary at its address set forth on the back cover of this Offer to Purchase; or

• the tendering shareholder must comply with the guaranteed delivery procedure set forth below.

16

          In accordance with Instruction 5 of the Letter of Transmittal, each shareholder desiring to tender Shares in the Offer must either (1) check the box in the section of the Letter of Transmittal captioned “Shares Tendered at Price Determined Pursuant to the Offer” or (2) check one of the boxes in the section of the Letter of Transmittal captioned “Price (in Dollars) per Share at Which Shares are Being Tendered,” indicating the price at which Shares are being tendered. A tender of Shares will be proper if, and only if, one of these boxes is checked on the Letter of Transmittal.

          If tendering shareholders wish to maximize the chance that their Shares will be purchased, they should check the box in the section on the Letter of Transmittal captioned “Shares Tendered At Price Determined Pursuant To The Offer.” Note that this election could have the effect of decreasing the purchase price determined by us which may result in the tendered Shares being purchased at the minimum price of $43.00 per Share.

          If tendering shareholders wish to indicate a specific price (in multiples of $0.25) at which their Shares are being tendered, they must check a box under the section captioned “Price (in Dollars) per Share at Which Shares are Being Tendered.” Tendering shareholders should be aware that this election could mean that none of their Shares will be purchased if they check a box other than the box representing the lowest price. A shareholder who wishes to tender Shares at more than one price must complete separate Letters of Transmittal for each price at which Shares are being tendered. The same Shares cannot be tendered (unless previously properly withdrawn in accordance with the terms of the Offer) at more than one price. In the event a shareholder has submitted multiple Letters of Transmittal in order to tender Shares at multiple prices, a separate notice of withdrawal must be submitted in accordance with the terms of this Offer with respect to each separate Letter of Transmittal in order for such withdrawals to be effective, as applicable. See Section 4.

          Odd Lot Holders must tender all of their Shares and also complete the section captioned “Odd Lots” in the Letter of Transmittal and, if applicable, in the Notice of Guaranteed Delivery, to qualify for the preferential treatment available to Odd Lot Holders as set forth in Section 1.

          Shareholders holding Shares through brokers, dealers, commercial banks, trust companies or other nominees are urged to consult such nominees to determine whether any transaction costs may apply.

          Participants in the Amended and Restated HCA Employee Stock Purchase Plan who wish to tender some or all of the Shares allocated to their account must follow the instructions in the “Letter to Participants in the Amended and Restated HCA Employee Stock Purchase Plan” furnished separately and return the Instruction Form included therewith to the ESPP Plan Administrator in accordance with those instructions. The Instruction Form must be received by the ESPP Plan Administrator not later than three business days prior to the Expiration Date (which, unless the Offer is extended, will require you to return the Instruction Form no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005), or no Shares allocated to the participant’s account will be tendered. Participants in the Amended and Restated HCA Employee Stock Purchase Plan may not use the Letter of Transmittal to tender any of the Shares held in their plan account. Participants in the Amended and Restated HCA Employee Stock Purchase Plan must use the Instruction Form to instruct the ESPP Plan Administrator to tender their Shares in the Amended and Restated HCA Employee Stock Purchase Plan.

          Participants in the Amended and Restated HCA Employee Stock Purchase Plan who also hold Shares outside of the plan will need to follow the instructions above regarding the Letter of Transmittal with respect to Shares held outside the plan and the Instruction Form in the “Letter to Participants in the Amended and Restated HCA Employee Stock Purchase Plan” with respect to Shares held under the Amended and Restated HCA Employee Stock Purchase Plan.

          Participants in the HCA 401(k) Plan who wish to tender some or all of the equivalent Shares allocated to their account must follow the instructions in the “Letter to Participants in the HCA 401(k) Plan” furnished separately and return the Instruction Form included therewith to U.S. Trust in accordance with those instructions. The Instruction Form must be received by U.S. Trust not later than three business days prior to the Expiration Date (which, unless the Offer is extended, will require you to return the Instruction Form no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005), or no

17

equivalent Shares allocated to the participant’s account will be tendered. Participants in the HCA 401(k) Plan may not use the Letter of Transmittal to tender any of the equivalent Shares held in their plan account. Participants in the HCA 401(k) Plan must use the Instruction Form to instruct U.S. Trust to tender their equivalent Shares in the HCA 401(k) Plan.

          Participants in the HCA 401(k) Plan who also hold Shares outside of the plan will need to follow the instructions above regarding the Letter of Transmittal with respect to Shares held outside the plan and the Instruction Form in the “Letter to Participants in the HCA 401(k) Plan” with respect to equivalent Shares held under the HCA 401(k) Plan.

          Signature Guarantees and Method of Delivery. No signature guarantee is required if:

          (a) The Letter of Transmittal is signed by the registered holder of the Shares (which term, for purposes of this Section 3, will include any participant in The Depository Trust Company (the “Book-Entry Transfer Facility”) whose name appears on a security position listing as the owner of the Shares) tendered and the holder has not completed either the box entitled “Special Delivery Instructions” or the box entitled “Special Payment Instructions” on the Letter of Transmittal; or

          (b) Shares are tendered for the account of a bank, broker, dealer, credit union, savings association or other entity that is a member in good standing of the Securities Transfer Agents Medallion Program or a bank, broker, dealer, credit union, savings association or other entity that is an “eligible guarantor institution,” as the term is defined in Rule 17Ad-15 under the Exchange Act (each of the foregoing constitutes an “Eligible Institution”). See Instruction 1 of the Letter of Transmittal.

          If a certificate for Shares is registered in the name of a person other than the person executing a Letter of Transmittal, or if payment is to be made to (or Shares not purchased or tendered are to be issued to) a person other than the registered holder, then the certificate must be endorsed or accompanied by an appropriate stock power, in either case, signed exactly as the name of the registered holder appears on the certificate, with the signature guaranteed by an Eligible Institution.

          In all cases, payment for Shares tendered and accepted for payment in the Offer will be made only after timely receipt by the Depositary of certificates for the Shares (or a timely confirmation of the book-entry transfer of the Shares into the Depositary’s account at the Book-Entry Transfer Facility as described above), a properly completed and duly executed Letter of Transmittal (or a manually signed facsimile of the Letter of Transmittal), an Agent’s Message, in the case of a book-entry transfer, or the specific acknowledgment, in the case of a tender through the Automated Tender Offer Program, of the Book-Entry Transfer Facility, and any other documents required by the Letter of Transmittal.

          The method of delivery of all documents, including certificates for Shares, the Letter of Transmittal and any other required documents, is at the election and risk of the tendering shareholder. If delivery is by mail, we recommend that shareholders use registered mail with return receipt requested, properly insured. In all cases, sufficient time should be allowed to ensure timely delivery.

          Book-Entry Delivery. The Depositary will establish an account with respect to the Shares for purposes of the Offer at the Book-Entry Transfer Facility within two business days after the date of this Offer to Purchase, and any financial institution that is a participant in the Book-Entry Transfer Facility’s system may make book-entry delivery of the Shares by causing the Book-Entry Transfer Facility to transfer Shares into the Depositary’s account in accordance with the Book-Entry Transfer Facility’s procedures for transfer. Although delivery of Shares may be effected through a book-entry transfer into the Depositary’s account at the Book-Entry Transfer Facility, either (1) a properly completed and duly executed Letter of Transmittal (or a manually signed facsimile of the Letter of Transmittal), with any required signature guarantees, an Agent’s Message in the case of a book-entry transfer or the specific acknowledgment in the case of a tender through the Automated Tender Offer Program of the Book-Entry Transfer Facility, and any other required documents must be transmitted to and received by the Depositary at one of its addresses set forth on the back cover of this Offer to Purchase on or before the Expiration Date, or (2) the guaranteed delivery procedure described below must be followed.

18

          Delivery of the Letter of Transmittal and any other required documents to the Book-Entry Transfer Facility does not constitute delivery to the Depositary.

          The term “Agent’s Message” means a message transmitted by the Book-Entry Transfer Facility to, and received by, the Depositary and forming a part of a Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has received an express acknowledgement from the participant in the Book-Entry Transfer Facility tendering Shares that such participant has received and agrees to be bound by the terms of the Letter of Transmittal and that we may enforce such agreement against the participant.

          Participants in the Book-Entry Transfer Facility may tender their Shares in accordance with the Automated Tender Offer Program to the extent it is available to them for the Shares they wish to tender. A shareholder tendering through the Automated Tender Offer Program must expressly acknowledge that the shareholder has received and agreed to be bound by the Letter of Transmittal and that the Letter of Transmittal may be enforced against that shareholder.

          Guaranteed Delivery. If a shareholder desires to tender Shares in the Offer and the certificates evidencing those Shares are not immediately available or cannot be delivered to the Depositary on or before the Expiration Date (or the procedure for book-entry transfer cannot be completed on a timely basis), or if time will not permit all required documents to reach the Depositary on or before the Expiration Date, the Shares still may be tendered, if all of the following conditions are satisfied:

          (1) the tender is made by or through an Eligible Institution;

          (2) the Depositary receives by hand, mail, overnight courier or facsimile transmission, on or before the Expiration Date, a properly completed and duly executed Notice of Guaranteed Delivery substantially in the form we have provided with this Offer to Purchase, including (where required) a guarantee by an Eligible Institution in the form set forth in the Notice of Guaranteed Delivery;

          (3) the certificates for all tendered Shares, in proper form for transfer (or confirmation of book-entry transfer of the Shares into the Depositary’s account at the Book-Entry Transfer Facility), together with a properly completed and duly executed Letter of Transmittal (or a manually signed facsimile of the Letter of Transmittal), including any required signature guarantees, an Agent’s Message in the case of a book-entry transfer or the specific acknowledgement in the case of a tender through the Automated Tender Offer Program of the Book-Entry Transfer Facility, and any other documents required by the Letter of Transmittal, are received by the Depositary within three NYSE trading days after the date of receipt by the Depositary of the Notice of Guaranteed Delivery; and

          (4) as to any tender of Shares which are to be acquired by employees upon exercise of stock options, the Company itself may elect to guarantee delivery of such Shares if and to the extent such Shares are purchased in the Offer.

          Return of Unpurchased Shares. If any tendered Shares are not purchased, or if less than all Shares evidenced by a shareholder’s certificates are tendered, certificates for unpurchased Shares will be returned promptly after the expiration or termination of the Offer or, in the case of Shares tendered by book-entry transfer at the Book-Entry Transfer Facility, the Shares will be credited to the appropriate account maintained by the tendering shareholder at the Book-Entry Transfer Facility, in each case without expense to the shareholder.

          Procedures for Participants in the Amended and Restated HCA Employee Stock Purchase Plan. A participant in the Amended and Restated HCA Employee Stock Purchase Plan may instruct the ESPP Plan Administrator to tender some or all of the Shares allocated to a participant’s account by completing the Instruction Form in accordance with the instructions in the “Letter to Participants in the Amended and Restated HCA Employee Stock Purchase Plan” furnished separately and returning it to the ESPP Plan Administrator in accordance with those instructions. All documents furnished to shareholders generally in connection with the Offer will be made available to participants whose plan accounts are credited with Shares. Participants in the Amended and Restated HCA Employee Stock Purchase Plan cannot use the Letter of Transmittal to direct the tender of Shares held under the plan, but must use the

19

Instruction Form included in the separate instruction letter sent to them. Participants in the Amended and Restated HCA Employee Stock Purchase Plan who also hold Shares outside of the plan, however, must use the Letter of Transmittal to tender Shares held outside of the plan and must complete the Instruction Form according to the instructions in the “Letter to Participants in the Amended and Restated HCA Employee Stock Purchase Plan” for shares held under the plan.

          Procedures for Participants in the HCA 401(k) Plan. A participant in the HCA 401(k) Plan may instruct U.S. Trust, the independent fiduciary of the HCA 401(k) Plan, to tender some or all of the equivalent Shares allocated to a participant’s account by completing the Instruction Form in accordance with the instructions in the “Letter to Participants in the HCA 401(k) Plan” furnished separately and returning it to U.S. Trust in accordance with those instructions. A participant’s equivalent Shares are equal to the total market value of a participant’s HCA Stock Fund account in the HCA 401(k) Plan divided by the closing market price per share of our common stock. All documents furnished to shareholders generally in connection with the Offer will be made available to participants whose plan accounts are credited with equivalent Shares. Participants in the HCA 401(k) Plan cannot use the Letter of Transmittal to direct the tender of equivalent Shares held under the plan, but must use the Instruction Form included in the separate instruction letter sent to them. Participants in the HCA 401(k) Plan who also hold Shares outside of the plan, however, must use the Letter of Transmittal to tender Shares held outside of the plan and must complete the Instruction Form according to the instructions in the “Letter to Participants in the HCA 401(k) Plan” for equivalent Shares held under the plan.

          The HCA 401(k) Plan is prohibited by law from selling equivalent Shares to us for a price that is less than the prevailing market price of our common stock. Accordingly, if a participant elects to tender equivalent Shares at a price that is lower than the closing price of our common stock on the date the Offer expires, the tender price a participant elects will be deemed to have been increased to the closest tender price that is not less than the closing price of our common stock on the NYSE on the date the Offer expires. This could result in a participant’s equivalent Shares not being purchased in the Offer. If the closing price of our common stock on the date the Offer expires is greater than the maximum price available in the Offer, none of the equivalent Shares will be tendered and a participant’s tender will be deemed to have been withdrawn.

          The proceeds received by the HCA 401(k) Plan from any tender of equivalent Shares from a participant’s plan account will be deposited in the participant’s HCA 401(k) Plan and invested in the 401(k) Plan’s Interest Income Fund unless and until the participant allocates the proceeds among the various investment funds under the HCA 401(k) Plan according to such participant’s personal investment strategy.

          Participants in the HCA 401(k) Plan are urged to read the separate “Letter to Participants in the HCA 401(k) Plan” and related materials carefully. This letter contains additional information regarding the potential tax consequences of tendering any equivalent Shares from a participant’s plan account.

          Restricted Shares. Shareholders to whom “restricted” Shares have been issued under our equity compensation plans (such as the “PEP” and “MSPP” plans) will not be able to tender such Shares unless the restrictions on transfer of such Shares (imposed by the terms of the applicable equity incentive plans or by the terms of the award agreement relating to such Shares) have expired. If a shareholder holds certificates representing such Shares on which the restrictions have expired, the participant may tender some or all of such Shares in accordance with procedures for tendering shares described above.

          HCA Stock Options. We are not offering, as part of the Offer, to purchase any stock options outstanding and tenders of stock options will not be accepted. Holders of stock options who wish to participate in the Offer may exercise their stock options and purchase Shares, and then tender the Shares under the Offer, provided that any exercise of a stock option and tender of Shares is in accordance with applicable law and the terms of the applicable plan and option agreements. In no event are any stock options to be delivered to the Depositary in connection with a tender of Shares hereunder. An exercise of a stock option cannot be revoked even if all or a portion of the Shares received upon the exercise or conversion and tendered in the Offer are not purchased in the Offer for any reason.

20

          Determination of Validity; Rejection of Shares; Waiver of Defects; No Obligation to Give Notice of Defects. All questions as to the number of Shares to be accepted, the Purchase Price to be paid for Shares to be accepted and the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by us, in our sole discretion, and our determination will be final and binding on all parties. We reserve the absolute right to reject any or all tenders of any Shares that we determine are not in proper form or the acceptance for payment of or payment for which may, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive any defect or irregularity in any tender with respect to any particular Shares or any particular shareholder, and our interpretation of the terms of the Offer will be final and binding on all parties. No tender of Shares will be deemed to have been properly made until all defects or irregularities have been cured by the tendering shareholder or waived by us. We will not, and none of the Lead Dealer Manager, the Dealer Manager, the Information Agent, the Depositary or any other person will be obligated to, give notice of any defects or irregularities in tenders, nor will any of them incur any liability for failure to give any notice.

          Tendering Shareholder’s Representation and Warranty; Our Acceptance Constitutes an Agreement. A tender of Shares pursuant to any of the procedures described above will constitute the tendering shareholder’s acceptance of the terms and conditions of the Offer, as well as the tendering shareholder’s representation and warranty to us that (1) the shareholder has a “net long position,” within the meaning of Rule 14e-4 promulgated by the SEC under the Exchange Act, in the “shares or equivalent securities at least equal to the shares being tendered” and (2) the tender of Shares complies with Rule 14e-4. It is a violation of Rule 14e-4 for a person, directly or indirectly, to tender Shares for that person’s own account unless, at the time of tender and at the end of the proration period or period during which Shares are accepted by lot (including any extensions thereof), the person so tendering (1) has a net long position equal to or greater than the amount of (a) Shares tendered or (b) other securities convertible into or exchangeable or exercisable for the Shares tendered and will acquire the Shares for tender by conversion, exchange or exercise and (2) will deliver or cause to be delivered the Shares in accordance with the terms of the Offer. Rule 14e-4 provides a similar restriction applicable to the tender or guarantee of a tender on behalf of another person. Our acceptance for payment of Shares tendered in the Offer will constitute a binding agreement between the tendering shareholder and us on the terms and conditions of the Offer.

          U.S. Federal Income Tax Backup Withholding. Under the U.S. federal income tax backup withholding rules, unless an exemption applies under the applicable law and regulations, 28% of the gross proceeds payable to a shareholder or other payee pursuant to the Offer must be withheld and remitted to the IRS, unless the shareholder or other payee provides its taxpayer identification number (employer identification number or social security number) to the Depositary (as payor) and certifies under penalties of perjury that the number is correct. Therefore, each tendering shareholder that is a United States Holder (as defined in Section 14) should complete and sign the Substitute Form W-9 included as part of the Letter of Transmittal so as to provide the information and certification necessary to avoid backup withholding unless the shareholder otherwise establishes to the satisfaction of the Depositary that the shareholder is not subject to backup withholding. If a United States Holder does not provide the Depositary with the correct taxpayer identification number, the United States Holder may be subject to penalties imposed by the IRS. If backup withholding results in an overpayment of taxes, a refund may be obtained from the IRS in accordance with its refund procedures. Certain “exempt recipients” (including, among others, all corporations and certain Non-United States Holders (as defined in Section 14)) are not subject to backup withholding. In order for a Non-United States Holder to qualify as an exempt recipient, that shareholder must submit an IRS Form W-8BEN (or successor form), signed under penalties of perjury, attesting to that shareholder’s exempt status. This statement can be obtained from the Depositary. See Instruction 14 of the Letter of Transmittal.

          To prevent U.S. federal income tax backup withholding equal to 28% of the gross payment made to shareholders for Shares purchased pursuant to the Offer, each shareholder that is a United States Holder and does not otherwise establish an exemption from the backup withholding must provide the Depositary with the shareholder’s correct taxpayer identification number and provide other information by completing the Substitute Form W-9 included as part of the Letter of Transmittal.

21

          Withholding for Non-United States Holders. Even if a Non-United States Holder has provided the required certification to avoid backup withholding, the Depositary will withhold U.S. federal income taxes equal to 30% of the gross payments payable to a Non-United States Holder or his agent unless the Depositary determines that a reduced rate of withholding is available under a tax treaty or that an exemption from withholding is applicable because the gross proceeds are effectively connected with the conduct of a trade of business within the United States (and, if a treaty applies, the gross proceeds are generally attributable to a United States permanent establishment maintained by such Non-United States Holder). To obtain a reduced rate of withholding under a tax treaty, a Non-United States Holder must deliver to the Depositary a properly completed and executed IRS Form W-8BEN (or successor form) before the payment is made. To obtain an exemption from withholding on the grounds that the gross proceeds paid pursuant to the Offer are effectively connected with the conduct of a trade or business within the United States, a Non-United States Holder must deliver to the Depositary a properly completed and executed IRS Form W-8ECI (or successor form). A Non-United States Holder that qualifies for an exemption from withholding by delivering IRS Form W-8ECI (or successor form) will generally be required to file a U.S. federal income tax return and generally will be subject to U.S. federal income tax on income derived from the sale of Shares pursuant to the Offer in the manner and to the extent described in Section 14 as if it were a United States Holder, and in the case of a foreign corporation, such income may be subject to the branch profit tax at a rate of 30% (or a lower rate specified in an applicable income tax treaty). The Depositary will determine a shareholder’s status as a Non-United States Holder and eligibility for a reduced rate of, or exemption from, withholding by reference to any outstanding, valid certificates or statements concerning eligibility for a reduced rate of, or exemption from, withholding (e.g., IRS Form W-8BEN (or successor form) or IRS Form W-8ECI (or successor form)) unless facts and circumstances indicate that reliance is not warranted.

          A Non-United States Holder may be eligible to obtain a refund of all or a portion of any tax withheld if the Non-United States Holder meets the “complete termination,” “substantially disproportionate” or “not essentially equivalent to a dividend” tests described in Section 14 that would characterize the exchange as a sale (as opposed to a dividend) with respect to which the Non-United States Holder is not subject to tax or is otherwise able to establish that no tax or a reduced amount of tax is due.

          Non-United States Holders are urged to consult their tax advisors regarding the application of U.S. federal income tax withholding, including eligibility for a withholding tax reduction or exemption, and the refund procedure.

          Lost or Destroyed Certificates. Shareholders whose certificates for part or all of their Shares have been lost, stolen, misplaced or destroyed should promptly notify the Depositary by checking the box immediately following the box entitled “Description of Shares Tendered” in the Letter of Transmittal and indicating the number of Shares so lost, destroyed or stolen, in accordance with Instruction 15 of the Letter of Transmittal. The shareholder will then be instructed as to the steps that must be taken in order to replace the certificates evidencing the lost, destroyed or stolen shares. Shareholders are requested to notify the Depositary immediately in order to permit timely processing of this documentation.

          Certificates for Shares, together with a properly completed Letter of Transmittal and any other documents required by the Letter of Transmittal, must be delivered to the Depositary and not to us. Any documents delivered to us will not be forwarded to the Depositary and will not be deemed to be properly tendered.

4. Withdrawal Rights

          Shares tendered in the Offer may be withdrawn at any time on or before the Expiration Date and, unless already accepted for payment by us in the Offer, may also be withdrawn at any time after 5:00 p.m., New York City time, December 13, 2005. In the event of any modification of the terms of the Offer, additional withdrawal rights will be available and announced. Except as otherwise provided in this Section 4, tenders of Shares pursuant to the Offer are irrevocable.

          For a withdrawal to be effective, a notice of withdrawal specifying (i) the name of the tendering shareholder, (ii) the number of Shares to be withdrawn and (iii) the name of the registered holder of the

22

Shares (if different from that of the person who tendered the Shares) must be in written or facsimile transmission form and must be received in a timely manner by the Depositary at its address set forth on the back cover of this Offer to Purchase. If the certificates for Shares to be withdrawn have been delivered or otherwise identified to the Depositary, then, before the release of the certificates, the tendering shareholder must also submit the serial numbers shown on the particular certificates for Shares to be withdrawn and the signature(s) on the Notice of Withdrawal must be guaranteed by an Eligible Institution (except in the case of Shares tendered for the account of an Eligible Institution). If Shares have been tendered in accordance with the procedure for book-entry transfers described in Section 3, the Notice of Withdrawal also must specify the name and the number of the account at the Book-Entry Transfer Facility to be credited with the withdrawn Shares and must otherwise comply with the Book- Entry Transfer Facility’s procedures. In the event a shareholder has submitted multiple Letters of Transmittal in order to tender Shares at multiple prices, a separate notice of withdrawal must be submitted in accordance with the terms of this Offer with respect to each separate Letter of Transmittal in order for such withdrawals to be effective, as applicable.

          All questions as to the form and validity, including the time of receipt, of any Notice of Withdrawal will be determined by us, in our sole discretion, which determination will be final and binding on all parties. Neither we nor any of the Lead Dealer Manager, the Dealer Manager, the Depositary, the Information Agent or any other person will be obligated to give notice of any defects or irregularities in any Notice of Withdrawal, nor will any of them incur liability for failure to give such notice.

          Participants in the Amended and Restated HCA Employee Stock Purchase Plan who wish to withdraw their Shares must follow the instructions in the “Letter to Participants in the Amended and Restated HCA Employee Stock Purchase Plan” furnished separately. Participants in the HCA 401(k) Plan who wish to withdraw their Shares must follow the instructions in the “Letter to Participants in the HCA 401(k) Plan” furnished separately.

          Withdrawals may not be rescinded, and any Shares properly withdrawn will be deemed not properly tendered for purposes of the Offer. However, withdrawn Shares may be re-tendered on or before the Expiration Date by again following one of the procedures described in Section 3.

          If we extend the Offer, are delayed in our purchase of Shares or are unable to purchase Shares in the Offer for any reason, then, without prejudice to our rights under the Offer, the Depositary may, subject to applicable law, retain tendered Shares on our behalf, and the Shares may not be withdrawn except to the extent tendering shareholders are entitled to withdrawal rights as described in this Section 4.

          Our reservation of the right to delay payment for Shares that we have accepted for payment is limited by Rule 13e-4(f)(5) under the Exchange Act, which requires that we must pay the consideration offered or return the Shares tendered promptly after termination or withdrawal of the Offer.

5. Purchase Of Shares And Payment Of Purchase Price

          Promptly following the Expiration Date, we (1) will determine which shareholders tendered Shares at or below the Purchase Price selected by us, and (2) will accept for payment and pay for (and thereby purchase) up to 50,000,000 Shares which are properly tendered at prices at or below the Purchase Price determined by us and not properly withdrawn on or before the Expiration Date. For purposes of the Offer, we will be deemed to have accepted for payment (and therefore purchased), subject to the “odd lot” priority, proration and conditional tender provisions of the Offer, Shares that are properly tendered at or below the Purchase Price selected by us and not properly withdrawn only when, as and if we give oral or written notice to the Depositary of our acceptance of the Shares for payment in the Offer.

          We will accept for payment and pay the per Share Purchase Price for all such Shares promptly after the Expiration Date. In all cases, payment for Shares tendered and accepted for payment in the Offer will be made promptly, but only after timely receipt by the Depositary of certificates for Shares, or of a timely Book-Entry Confirmation of Shares into the Depositary’s account at the Book-Entry Transfer Facility, and a properly completed and duly executed Letter of Transmittal (or manually signed facsimile of the Letter of Transmittal), an Agent’s Message, in the case of a book-entry transfer, or the specific

23

acknowledgement, in the case of a tender through the Automated Tender Offer Program of the Book-Entry Transfer Facility, and any other required documents.

          We will pay for Shares purchased in the Offer by depositing the aggregate purchase price for the Shares with the Depositary, which will act as agent for tendering shareholders for the purpose of receiving payment from us and transmitting payment to the tendering shareholders.

          In the event of proration, we will determine the Proration Factor and pay for those tendered Shares accepted for payment promptly after the Expiration Date. However, we do not expect to be able to announce the final results of any proration and commence payment for Shares purchased until approximately seven business days after the Expiration Date. Certificates for all Shares tendered and not purchased, including all Shares tendered at prices in excess of the Purchase Price determined by us and Shares not purchased due to proration or conditional tenders will be returned or, in the case of Shares tendered by book-entry transfer, will be credited to the account maintained with the Book-Entry Transfer Facility by the participant who delivered the Shares, to the tendering shareholder at our expense promptly after the Expiration Date or termination of the Offer without expense to the tendering shareholders. We will not pay interest on the Purchase Price for any reason, including but not limited to, by reason of any delay in making payment. In addition, if certain events occur, we may not be obligated to purchase Shares in the Offer. See Sections 7 and 9.

          We will pay all stock transfer taxes, if any, payable on the transfer to us of Shares purchased in the Offer. If, however, payment of the Purchase Price is to be made to, or (in the circumstances permitted by the Offer) if unpurchased Shares are to be registered in the name of, any person other than the registered holder, or if tendered certificates are registered in the name of any person other than the person signing the Letter of Transmittal, the amount of all stock transfer taxes, if any (whether imposed on the registered holder or the other person), payable on account of the transfer to the person will be deducted from the Purchase Price unless satisfactory evidence of the payment of the stock transfer taxes, or exemption from payment of the stock transfer taxes, is submitted. See Instruction 8 of the Letter of Transmittal.

          Any tendering United States Holder or other payee who fails to complete fully, sign and return to the Depositary the Substitute Form W-9 included with the Letter of Transmittal may be subject to required U.S. federal income tax backup withholding of 28% of the gross proceeds paid to the shareholder or other payee in the Offer. See Section 3. Also see Section 3 if you are a tendering Non-United States Holder for U.S. federal income tax withholding considerations relevant to you.

6. Conditional Tender Of Shares

          Under certain circumstances and subject to the exceptions for Odd Lot Holders described in Section 1, we may prorate the number of Shares purchased in the Offer. As discussed in Section 14, the number of Shares to be purchased from a particular shareholder may affect the tax treatment of the purchase to the shareholder and the shareholder’s decision whether to tender. The conditional tender alternative is made available so that a shareholder may seek to structure the purchase of Shares from the shareholder in the Offer in such a manner that it will be treated as a sale of such Shares by the shareholder, rather than the payment of a dividend to the shareholder, for U.S. federal income tax purposes. Accordingly, a shareholder may tender Shares subject to the condition that a specified minimum number of the shareholder’s Shares tendered must be purchased if any Shares tendered are purchased. Each shareholder is urged to consult with his or her own tax advisor.

          If you wish to make a conditional tender you must indicate this in the box captioned “Conditional Tender” in the Letter of Transmittal and, if applicable, the Notice of Guaranteed Delivery. In this box in the Letter of Transmittal and the Notice of Guaranteed Delivery, you must calculate and appropriately indicate the minimum number of Shares that must be purchased from you if any are to be purchased. After the Offer expires, if more than 50,000,000 Shares (or such greater number of Shares as we may elect to purchase, subject to applicable law) are properly tendered and not properly withdrawn and we must prorate our acceptance of and payment for tendered Shares, we will calculate a preliminary proration percentage based upon all Shares properly tendered, conditionally or unconditionally. If the effect of this

24

preliminary proration would be to reduce the number of Shares to be purchased from any shareholder below the minimum number specified by that shareholder, the conditional tender will automatically be regarded as withdrawn and will be returned promptly after the Expiration Date, unless chosen by lot for reinstatement as discussed in the next paragraph.

          After giving effect to these withdrawals, we will accept the remaining Shares properly and unconditionally tendered on a pro rata basis, if necessary. If we are able to purchase all of the remaining unconditionally tendered Shares and the number of Shares that we would purchase would be below 50,000,000, then, to the extent feasible, we will select enough of the conditional tenders (including those that would otherwise have been deemed withdrawn pursuant to the immediately preceding paragraph, if such shareholders conditionally tendered all of their Shares) to permit us to purchase 50,000,000 Shares. In selecting these conditional tenders, we will select by random lot and will select only from shareholders who tendered all of their Shares. Upon selection by lot, if any, we will limit our purchase in each case to the designated minimum number of Shares to be purchased.

7. Conditions Of The Offer

          Notwithstanding any other provision of the Offer, we will not be required to accept for payment, purchase or pay for Shares tendered, and we may terminate or amend the Offer or may postpone the acceptance for payment of, or the purchase of and the payment for, Shares tendered, subject to the rules under the Exchange Act, if at any time on or after October 14, 2005 and on or before the Expiration Date any of the following events have occurred (or have been determined by us to have occurred) that, in our reasonable judgment and regardless of the circumstances giving rise to the event or events (including any action or omission to act by us), makes it inadvisable to proceed with the Offer or with acceptance for payment:

          (a) make the acceptance for payment of, or payment for, some or all of the Shares illegal, or otherwise restrict or prohibit consummation of the Offer;

25

          (b) delay or restrict our ability, or render us unable, to accept for payment or pay for some or all of the Shares;

• there has occurred any of the following:

          (a) any general suspension of trading in, or limitation on prices for, securities in any U.S. national securities exchange or in the over-the-counter market;

          (c) the commencement or escalation of a war, armed hostilities or other international or national calamity, including an act or acts of terrorism, directly or indirectly involving the United States;

          (d) any limitation, whether or not mandatory, by any governmental, regulatory or administrative agency or authority on, or any disruption or adverse change in the financial or capital markets generally or the market for loan syndications in particular or any other event that, in our reasonable judgment, could materially affect, the extension of credit by banks or other lending institutions in the United States;

          (e) any significant decrease in the market price of our common stock or in the market prices of equity securities generally in the United States, any significant increase in the interest rate, distribution rate or other significant change in the terms for debt security offerings in the U.S., or any changes in the general political, market, economic or financial conditions in the United States or abroad that could have, in our reasonable judgment, a material adverse effect on our and our subsidiaries’ business, condition (financial or otherwise), assets, liabilities, income, operations or prospects, taken as a whole, or on the trading in the Shares, the proposed financing for the Offer or on the benefits of the Offer to us; or

          (f) in the case of any of the foregoing existing at the time of the commencement of the Offer, a material acceleration or worsening thereof;

          (a) any entity, “group” (as that term is used in Section 13(d)(3) of the Exchange Act) or person has acquired or proposes to acquire beneficial ownership of more than 5% of our outstanding Shares, whether through the acquisition of stock, the formation of a group, the grant of any option or right, or otherwise (other than as and to the extent disclosed in a Schedule 13D or Schedule 13G filed with the SEC on or before October 12, 2005); or

          (b) any entity, group or person who has filed a Schedule 13D or Schedule 13G with the SEC on or before October 12, 2005 has acquired or proposes to acquire, whether through the acquisition of stock, the formation of a group, the grant of any option or right, or otherwise (other than by virtue of the Offer), beneficial ownership of an additional 2% or more of our outstanding Shares;

26

• any person, entity or group has filed a Notification and Report Form under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, reflecting an intent to acquire us or any of our Shares or has made a public announcement reflecting an intent to acquire us or any of our subsidiaries or any of our respective assets or securities, other than in connection with a transaction authorized by our Board of Directors;

In certain circumstances, if we waive any of the conditions described above, we may be required to extend the Offer. Any determination by us concerning the events described above will be final and binding on all parties.

          On October 12, 2005, the last full trading day before the announcement of the Offer, the last reported sale price of the Shares as reported on the NYSE was $46.69. We urge shareholders to obtain current market quotations for the Shares.

          In January 2004, our Board of Directors approved an increase in our quarterly dividend from $0.02 per Share to $0.13 per Share. The Board of Directors declared the initial $0.13 per share dividend payable on June 1, 2004 to shareholders of record on May 1, 2004. Additionally, in January 2005, our

27

Board of Directors approved an increase in our quarterly dividend from $0.13 per Share to $0.15 per Share. The Board of Directors declared the initial $0.15 per share dividend payable on June 1, 2005 to shareholders of record on May 1, 2005. The declaration and payment of future dividends by HCA will depend upon many factors, including our earnings, financial position, business needs, capital and surplus and regulatory considerations.

9. Source And Amount Of Funds

          Assuming that the maximum 50,000,000 Shares are tendered in the Offer at a price between $43.00 and $50.00 per Share, the aggregate purchase price will range from approximately $2,150,000,000 to $2,500,000,000. We expect that our fees and expenses for the Offer, including structuring and arrangement fees for the credit and loan facilities described below, will be approximately $10 million, which we expect to pay from cash on hand.

          We anticipate that we will obtain the funds necessary to purchase Shares tendered in the Offer by utilizing approximately $500 million of cash on hand, by borrowing approximately $1 billion from our existing revolving credit facility and by borrowing approximately $1 billion pursuant to the terms and conditions of the Term Facility Commitment Letter as further described below. In connection with the Offer, we are seeking an amendment to our existing credit facility as further described below. If we are unable to obtain the required amendment prior to the Expiration Date, we intend to refinance our existing revolving credit facility and the related senior term loan facility with a new $2.425 billion facility pursuant to the terms and conditions contained in the Refinancing Commitment Letter. While we have obtained commitments pursuant to the Term Facility Commitment Letter and the Refinancing Commitment Letter, these commitments are contingent on the satisfaction of various conditions as further described below. Accordingly, as discussed in Section 7, in addition to the other conditions described in this Offer to Purchase, the Offer will be subject to our amending our existing credit facility or refinancing it pursuant to the terms and conditions contained in the Refinancing Commitment Letter and obtaining the necessary financing for the Offer pursuant to the terms and conditions contained in the Term Facility Commitment Letter. We do not have alternative financing plans.

          Existing Revolving Credit Facility. We currently have an unsecured revolving credit facility in an aggregate principal amount of $1.75 billion with J.P. Morgan Securities Inc., as Sole Advisor, Lead Arranger and Bookrunner, certain other agents and arrangers, JPMorgan Chase Bank, N.A. (“JP Morgan Chase Bank”), as Administrative Agent, and several banks and other financial institutions from time to time parties thereto. The revolving credit facility matures on November 9, 2009. Interest on the outstanding balances under the revolving credit facility is payable, at the Company’s option, at an alternate base rate, or at the one-, two-, three- or six-month London Interbank Offered Rate (“LIBOR”), plus a margin ranging from 0.400% to 1.000%, depending on the long-term unsecured debt ratings of the Company.

          In connection with the Offer, we are seeking an amendment to our existing credit facility to modify the compliance levels for the Company’s required ratio of consolidated total debt to consolidated capitalization. If we are unable to obtain the required amendment prior to the Expiration Date, we intend to replace the existing credit facility with a new credit facility pursuant to the terms of a Commitment Letter, dated as of October 13, 2005, from J.P. Morgan Securities Inc. and JPMorgan Chase Bank to the Company (the “Refinancing Commitment Letter”).

          Refinancing Commitment Letter. The following summary of the material terms of the Refinancing Commitment Letter is qualified in its entirety by the terms of the actual Refinancing Commitment Letter, which is filed as an exhibit to the Issuer Tender Offer Statement on Schedule TO. The following summary may not contain all of the information about the Refinancing Commitment Letter that is important to you. We encourage you to read the Refinancing Commitment Letter carefully and in its entirety.

          JPMorgan Chase Bank has committed, subject to the terms and conditions set forth in the Refinancing Commitment Letter, to provide up to $2.425 billion in financing to the Company, consisting of two facilities (the “JPMorgan Facilities”): a senior term loan facility in an aggregate principal amount

28

of $675 million (the “JPMorgan Term Facility”) and a senior revolving credit facility (including a competitive bid facility similar to the one provided in the Company’s existing bank credit facility) in an aggregate principal amount of $1.75 billion (the “JPMorgan Revolving Facility”). The JPMorgan Facilities will be used to refinance outstanding indebtedness under the Company’s existing revolving credit facility and the related senior term loan facility of the Company and for general corporate purposes (including but not limited to the redemption or purchase of outstanding securities of the Company).

          The JPMorgan Term Facility will provide for a five year maturity and will amortize in non-ratable quarterly installments in years two through five. The JPMorgan Revolving Facility will provide for a five year maturity. Interest on the outstanding balances under the JPMorgan Revolving Facility is payable, at the Company’s option, at an alternate base rate (or “ABR,” as that term is defined in the Refinancing Commitment Letter), or at LIBOR plus a margin ranging from 0.400% to 1.000% depending on the long-term unsecured debt rating of the Company. Interest on the outstanding balances under the JPMorgan Term Facility is payable, at the Company’s option, at the ABR plus a margin ranging from 0.000% to 0.250%, or at LIBOR plus a margin ranging from 0.500% to 1.250%, depending on the long-term unsecured debt rating of the Company.

          The Company may make optional prepayments of loans under the JPMorgan Facilities, in whole or in part, in minimum amounts of $5 million, without premium or penalty, and subject to the reimbursement of the lenders’ redeployment costs in the case of a prepayment of LIBOR borrowings on a day other than the last day of the relevant interest period for that borrowing.

          JPMorgan Chase Bank’s obligation to make the loans described above is subject to customary conditions precedent and, among others:

• the repayment and termination of the existing bank credit facility of the Company;

• there shall not have occurred or become known to JPMorgan Chase Bank any condition or change in the financial condition of the Company and its subsidiaries, taken as a whole, that is material and adverse;

• JPMorgan Chase Bank not becoming aware of any information or other matter affecting the Company and its subsidiaries, taken as a whole, that is material and adverse and is inconsistent with any such information or other matter disclosed to it prior to the date of the Refinancing Commitment Letter;

• A minimum long-term unsecured debt rating from Standard & Poor’s Ratings Group and Moody’s Investor Service of at least BB+ and Ba2, respectively (with a stable outlook);

• the absence of any continuing default under the definitive loan documents; and

• the accuracy of all representations and warranties made in the definitive loan documents, including the absence of a material adverse change in the business or assets or in the condition, financial or otherwise, of the Company and its subsidiaries, on a consolidated basis.

          The terms of the JPMorgan Facilities will provide for customary representations and warranties and negative and affirmative covenants, and will also include customary events of default such as payment defaults, cross-defaults to other indebtedness of the Company, bankruptcy and insolvency, and a change in control.

          JPMorgan Chase Bank and J.P. Morgan Securities Inc. have the ability to syndicate, before or after the consummation of the Offer, the JPMorgan Facilities to a group of financial institutions, in consultation with the Company. We currently expect to repay amounts borrowed under the JPMorgan Facilities, if any, from the anticipated net proceeds from the sale of notes to be offered in one or more public or private offerings and/or from available cash flow or the proceeds of other borrowings from time to time.

          We expect that any undrawn funds under the JPMorgan Facilities, following the consummation of the Offer and the repayment of amounts required to terminate our existing credit facility, will be generally available to meet our business needs.

29

          Term Facility Commitment Letter. The following summary of the material terms of the Commitment Letter, dated as of October 13, 2005, from J.P. Morgan Securities Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, JPMorgan Chase Bank and Merrill Lynch Capital Corporation to the Company (the “Term Facility Commitment Letter”), is qualified in its entirety by the terms of the actual Term Facility Commitment Letter, which is filed as an exhibit to the Issuer Tender Offer Statement on Schedule TO. The following summary may not contain all of the information about the Term Facility Commitment Letter that is important to you. We encourage you to read the Term Facility Commitment Letter carefully and in its entirety.

          JPMorgan Chase Bank and Merrill Lynch Capital Corporation have each individually committed, subject to the terms and conditions set forth in the Term Facility Commitment Letter, to provide to the Company 50% of a senior term loan facility of up to $1 billion (the “JPMorgan/ Merrill Term Facility”). The JPMorgan/ Merrill Term Facility will be used to finance the consummation of the Offer.

          The JPMorgan/ Merrill Term Facility will provide for a six-month maturity. Interest on the outstanding balances under the JPMorgan/ Merrill Term Facility is payable, at the Company’s option, at an alternate base rate (or “ABR” as that term is defined in the Term Facility Commitment Letter) or at LIBOR, in each case plus the margin applicable to such loans under the Company’s credit facility as of the date of closing of the JPMorgan/ Merrill Term Facility.

          The terms of the JPMorgan/ Merrill Term Facility will provide for customary mandatory prepayment provisions.

          The Company may make optional prepayments of loans under the JPMorgan/ Merrill Term Facility, in whole or in part, without premium or penalty, and subject to the reimbursement of lenders’ redeployment costs in the case of a prepayment of LIBOR borrowings on a day other than the last day of the relevant interest period for that borrowing.

          JPMorgan Chase Bank’s and Merrill Lynch Capital Corporation’s obligations to make the loans described above are subject to customary conditions precedent and, among others:

• either (i) the execution and delivery of the amendment to the Company’s existing credit facility discussed above, or (ii) the termination of the Company’s existing credit facility and the execution and delivery of definitive documentation for the JPMorgan Facilities;

• there shall not have occurred or become known to JPMorgan Chase Bank and Merrill Lynch Capital Corporation any condition or change in the financial condition of the Company and its subsidiaries taken as a whole that is material and adverse;

• JPMorgan Chase Bank and Merrill Lynch Capital Corporation not becoming aware of any information or other matter affecting the Company and its subsidiaries taken as a whole that is material and adverse and is inconsistent with any such information or other matter disclosed to them prior to the date of the Term Facility Commitment Letter;

• A minimum long-term unsecured debt rating from Standard & Poor’s Ratings Group and Moody’s Investor Service of at least BB+ and Ba2, respectively (with a stable outlook);

• the absence of any continuing default under the definitive loan documents; and

• the accuracy of all representations and warranties made in the definitive loan documents, including the absence of a material adverse change in the business or assets or in the condition, financial or otherwise, of the Company and its subsidiaries, on a consolidated basis.

          The terms of the JPMorgan/ Merrill Term Facility will provide for customary representations and warranties and negative and affirmative covenants, and will also include customary events of default such as payment defaults, cross-defaults to other indebtedness of the Company, bankruptcy and insolvency, and a change in control.

          JPMorgan Chase Bank, J.P. Morgan Securities Inc., Merrill Lynch Capital Corporation and Merrill Lynch, Pierce, Fenner & Smith Incorporated have the ability to syndicate, before or after the

30

consummation of the Offer, the JPMorgan/ Merrill Term Facility to a group of financial institutions, in consultation with the Company. We currently intend to repay amounts borrowed under the JPMorgan/ Merrill Term Facility from the anticipated net proceeds from the sale of notes to be offered in one or more public or private offerings and/or from available cash flow, the anticipated proceeds from the sale of ten hospitals or the proceeds of other borrowings from time to time.

          General. We will incur increased indebtedness in connection with the Offer and, as a result, will be more leveraged. Increased leverage could have certain material adverse effects on us, including, but not limited to, the following: (i) our ability to obtain additional financing in the future for acquisitions, working capital, capital expenditures, and general corporate or other purposes could be impaired, or any such financing may not be available on terms favorable to us; (ii) a substantial portion of our cash flow could be required for debt service and, as a result, might not be available for our operations or other purposes; (iii) any substantial decrease in net operating cash flows or any substantial increase in expenses could make it difficult for us to meet our debt service requirements or force us to modify our operations or sell assets; (iv) our ability to withstand competitive pressures may be decreased; and (v) our level of indebtedness may make us more vulnerable to economic downturns, and reduce our flexibility in responding to changing business, regulatory and economic conditions.

          Our ability to repay expected borrowings under our existing revolving credit facility, as proposed to be amended, or the proposed JPMorgan Facilities, and the JPMorgan/ Merrill Term Facility, and to meet our other debt or contractual obligations (including continued compliance with applicable financial covenants) will depend upon one or more of the following: our future performance and our cash flow from operations, our ability to realize anticipated net proceeds from the sale of notes we expect to offer in one or more public or private offerings and/or our ability to realize anticipated net proceeds from the sale of ten hospitals, each of which is subject to prevailing economic conditions and financial, business and other known and unknown risks and uncertainties, certain of which are beyond our control. These factors include, without limitation, those described in this Offer to Purchase under “Forward-Looking Statements.”

          Management believes that cash flows from operations, anticipated proceeds from the sale of ten hospitals, amounts available under our existing revolving credit facility, as proposed to be amended, or the proposed JPMorgan Facilities, and the JPMorgan/ Merrill Term Facility and the Company’s anticipated access to public and private debt markets are sufficient to meet the Company’s expected liquidity needs.

(a)  Revenues and revenue per equivalent admission have been adjusted to exclude the discounts under HCA’s uninsured discount policy (non-GAAP financial measures). On January 1, 2005, HCA modified its policies to provide discounts to uninsured patients who do not qualify for Medicaid or charity care. These discounts are similar to those provided to many local managed care plans. In implementing the discount policy, HCA first attempts to qualify uninsured patients for Medicaid, other federal or state assistance or charity care. If an uninsured patient does not qualify for these programs, the uninsured discount is applied. For the six months ended June 30, 2005, HCA recorded $293 million of uninsured discounts. The Company believes that these non-GAAP financial measures are useful to investors to provide disclosures of its results of operations on the same basis as that used by management. Management uses this information to compare revenues and revenue per equivalent admission for periods prior and subsequent to the January 1, 2005 implementation of the uninsured discount policy. These non-GAAP financial measures should not be considered an alternative to GAAP financial measures. The Company believes this supplemental information provides it and the users of its financial statements with useful information for period-to-period comparisons. Investors are encouraged to use GAAP measures when evaluating the Company’s overall financial performance.

(b)	Excludes seven facilities at June 30, 2005 and 2004, seven facilities at December 31, 2004, seven facilities at December 31, 2003, and six facilities at December 31, 2002 that are not consolidated (accounted for using the equity method) for financial reporting purposes.
(c)	Licensed beds are those beds for which a facility has been granted approval to operate from the applicable state licensing agency.
(d)	Represents the total number of patients admitted to our hospitals. Management and certain investors use admissions as a general measure of inpatient volume.
(e)	Management and certain investors use equivalent admissions as a general measure of combined inpatient and outpatient volume. Equivalent admissions are computed by multiplying admissions (inpatient volume) by the sum of gross inpatient revenue and gross outpatient revenue and then dividing the resulting amount by gross inpatient revenue. The equivalent admissions computation “equates” outpatient revenue to the volume measure (admissions) used to measure inpatient volume, resulting in a general measure of combined inpatient and outpatient volume. Prior year amounts have been reclassified to conform to the 2005 presentation.
(f)	Represents the average number of days admitted patients stay in our hospitals.

          Summary Unaudited Pro Forma Consolidated Financial Data. The following table sets forth summary unaudited pro forma consolidated financial data for the year ended December 31, 2004 and the six months ended June 30, 2005, certain ratios for the year ended December 31, 2004 and the twelve months ended June 30, 2005 and our financial position at June 30, 2005. This summary unaudited pro forma consolidated financial data gives effect to the purchase of Shares pursuant to the Offer as if such purchase had occurred at the dates indicated. This information should be read in conjunction with Summary Historical Consolidated Financial Data and our audited consolidated financial statements and the related notes filed as part of our Annual Report on Form 10-K for the year ended December 31, 2004 and the unaudited condensed consolidated financial statements and the related notes filed as part of our Quarterly Report on Form 10-Q for the quarter ended June 30, 2005. This summary unaudited pro forma consolidated financial data is not necessarily indicative of either our financial position or results of operations, which actually would have been attained, had the purchase of Shares pursuant to the Offer and the related refinancing been completed at the dates indicated, or, will be achieved in the future. This summary unaudited pro forma consolidated financial data has been included herein for informational and comparative purposes only. We have included the summary unaudited pro forma consolidated financial data solely for the purpose of providing shareholders with information that may be useful for purposes of considering and evaluating the Offer. Our future results are subject to prevailing economic and industry specific conditions and financial, business and other known and unknown risks and uncertainties, certain of which are beyond our control. These factors include, without limitation, those described in this Offer under “Forward-Looking Statements.”

          The pro forma amounts have been calculated assuming that we complete the Offer for 50,000,000 Shares at a price of $50.00 per share. We anticipate that we will obtain the funds necessary to purchase Shares tendered in the Offer by utilizing approximately $500 million of cash on hand, by borrowing approximately $1 billion under our revolving credit facility, as proposed to be amended, or pursuant to the terms and conditions contained in the Refinancing Commitment Letter, and by borrowing approximately $1 billion pursuant to the terms and conditions of the Term Facility Commitment Letter.

(a)	Pro forma data is presented giving effect to the Offer as of the beginning of the applicable period.
(b)	Pro forma interest income, included in “other operating expenses”, has been reduced under the assumption that $500 million of cash on hand will be used to finance the Offer. A rate of 3.73% has been used to compute pro forma interest income. Pro forma interest expense has been computed under the assumption that the Company has drawn $1 billion under the Company’s existing revolving credit facility and $1 billion under the JP Morgan/ Merrill Term Facility. The JP Morgan/ Merrill Term Facility has a six-month term and it is assumed that at the end of the term, the JP Morgan/ Merrill Term Facility is repaid with proceeds of $1 billion from expected public debt issuances. Definitive agreements have been signed under which the Company expects to sell ten hospitals and related working capital and receive net cash proceeds of approximately $590 million. It is anticipated that these proceeds will be used to reduce the actual amount of public debt issuances; however, for pro forma purposes, these expected cash proceeds have not been considered. The revolving credit facility is subject to a variable interest rate, and an interest rate of 4.82% has been used to compute pro forma interest for the January 1, 2004 through June 30, 2005 time period. The JP Morgan/ Merrill Term Facility is subject to a variable interest rate, and an interest rate of 5.34% has been used to compute pro forma interest for the period January 1, 2004 through June 30, 2004 and for the period January 1, 2005 through June 30, 2005. A fixed interest rate of 7.00% has been used to compute pro forma interest expense on the public debt issuance for the period July 1, 2004 through December 31, 2004.
(c)	Pro forma income statement data is presented giving effect to the transaction as of January 1, 2004 and pro forma balance sheet data is presented giving effect to the transaction at the respective balance sheet dates.
(d)	Total capitalization includes total debt, minority interests in equity of consolidated entities and stockholders’ equity.
(e)	Pro forma data is presented giving effect to the transaction as of June 30, 2005.

Bracken, who gifted 500 shares to a charitable organization on August 9, 2005; (ii) Russell K. Harms who, in connection with his appointment to Chief Financial Officer — Central Group, received 7,800 restricted Shares and 31,300 non-qualified options to purchase Shares at an exercise price of $47.92 on October 1, 2005; (iii) W.

The restricted Shares granted to Messrs. Harms, Rutledge and Stinnett vest ratably in 33¹/3% increments on each of the first, second and third anniversaries of the date of grant and will become fully vested upon the occurrence of a change in control of the Company (as defined in the award agreements) or the termination of the executive by reason of death or disability, and the non-qualified options to purchase Shares granted to Messrs. Harms, Rutledge and Stinnett vest and become exercisable ratably in 25% increments on each of the first, second, third and fourth anniversaries of the date of grant and will become fully vested upon the occurrence of a change in control of the Company (as defined in the award agreements) or the termination of the executive by reason of retirement, death or disability.

          Rule 10b5-1 Trading Plan. Thomas F. Frist, Jr., M.D. entered into a Rule 10b5-1 Trading Plan with Avondale Partners, LLC, dated May 18, 2005, pursuant to which Avondale Partners, LLC has agreed to sell up to 1,200,000 shares on behalf of Dr. Frist at a price of $60.25 per share or higher in accordance with the instructions set forth in the plan.

13. Certain Legal Matters; Regulatory Approvals

          We are not aware of any license or regulatory permit material to our business that might be adversely affected by our acquisition of Shares as contemplated in the Offer or of any approval or other action by any government or governmental, administrative or regulatory authority or agency, domestic, foreign or supranational, that would be required for our acquisition or ownership of Shares as contemplated by the Offer. Should any approval or other action be required, we currently contemplate that we will seek that approval or other action. We cannot predict whether we will be required to delay the acceptance for payment of or payment for Shares tendered in the Offer pending the outcome of any such matter. There can be no assurance that any approval or other action, if needed, would be obtained or would be obtained without substantial conditions or that the failure to obtain the approval or other action might not result in adverse consequences to our business. Our obligations under the Offer to accept for payment and pay for Shares are subject to certain conditions. See Section 7.

14. Certain U.S. Federal Income Tax Consequences

          The following discussion is a summary of certain U.S. federal income tax consequences to our shareholders of an exchange of Shares for cash pursuant to the Offer. This discussion is general in nature and does not discuss all aspects of U.S. federal income taxation that may be relevant to a particular shareholder in light of the shareholder’s particular circumstances, or to certain types of shareholders subject to special treatment under U.S. federal income tax laws (such as insurance companies, tax-exempt organizations, regulated investment companies, real estate investment trusts, United States Holders, as defined below, whose “functional currency” is not the United States dollar, partnerships or other entities treated as partnerships for federal income tax purposes, persons holding Shares as part of a hedging, integrated, conversion or constructive sale transaction or a straddle, financial institutions, brokers, dealers in securities or currencies and traders that elect to mark-to-market their securities). In addition, the discussion does not consider the effect of any alternative minimum taxes or foreign, state, local or other tax laws, or any U.S. tax considerations (e.g., estate or gift tax) other than U.S. federal income tax considerations, that may be applicable to particular shareholders. Further, this summary assumes that shareholders hold their Shares as “capital assets” (generally, property held for investment) within the meaning of section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”) and generally assumes that they did not receive their Shares through the exercise of employee stock options or otherwise as compensation.

          If a partnership or other entity treated as a partnership for U.S. federal income tax purposes holds Shares, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. A partnership holding Shares and partners in such partnership should consult their tax advisors about the U.S. federal income tax consequences of an exchange of Shares for cash pursuant to the Offer.

          This summary is based on the Code and applicable U.S. Treasury regulations, rulings, administrative pronouncements and judicial decisions thereunder as of the date hereof, all of which are subject to change or differing interpretations at any time with possible retroactive effect.

          We have not sought, nor will we seek, any ruling from the IRS with respect to the matters discussed below. There can be no assurances that the IRS will not take a different position concerning tax consequences of the sale of Shares to the Company pursuant to the Offer or that any such position would not be sustained.

          As used herein, a “United States Holder” means a beneficial owner of Shares that is for U.S. federal income tax purposes (1) a citizen or resident of the United States, (2) a corporation or other entity taxed as a corporation created or organized in or under the laws of the United States or any political

42

subdivision thereof, (3) an estate the income of which is subject to United States federal income taxation regardless of its source or (4) a trust if (x) the administration of the trust is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust, or (y) it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a United States person.

          As used herein, a “Non-United States Holder” means a beneficial owner of Shares that is not a United States Holder.

          Each shareholder is advised to consult its own tax advisor to determine the federal, state, local, foreign and other tax consequences to it of the Offer.

          Consequences to United States Holders. An exchange of Shares for cash pursuant to the Offer will be a taxable transaction to a United States Holder for U.S. federal income tax purposes. If the receipt of cash by a United States Holder in exchange for the tender of Shares pursuant to the Offer is treated as a sale or exchange (as described below) of such Shares for U.S. federal income tax purposes, the United States Holder will recognize capital gain or loss equal to the difference between (1) the amount of cash received by the United States Holder for such Shares and (2) the United States Holder’s “adjusted tax basis” for such Shares at the time of the sale. Generally, a United States Holder’s adjusted tax basis for the Shares will be equal to the cost of the Shares to the United States Holder. This gain or loss will be characterized as long-term capital gain or loss if the United States Holder’s holding period for the Shares that were sold exceeds one year as of the date we are treated as purchasing the Shares in the Offer for U.S. federal income tax purposes. In the case of a United States Holder that is an individual, trust or estate, the maximum rate of U.S. federal income tax applicable to net capital gain on Shares held for more than one year is generally 15%. A United States Holder’s ability to deduct capital losses may be limited. A United States Holder must calculate gain or loss separately for each block of Shares (generally, shares acquired at the same cost in a single transaction) we purchase from the United States Holder under the Offer.

          A United States Holder’s exchange of Shares for cash pursuant to the Offer will be treated as a sale or exchange of the Shares for federal income tax purposes pursuant to Section 302 of the Code if the sale:

• results in a “complete termination” of the shareholder’s stock interest in us under Section 302(b)(3) of the Code;

• is a “substantially disproportionate” redemption with respect to the shareholder under Section 302(b)(2) of the Code; or

• is “not essentially equivalent to a dividend” with respect to the shareholder under Section 302(b)(1) of the Code.

          In determining whether any of these tests have been met, a United States Holder must take into account not only the Shares that the shareholder actually owns, but also the Shares that it constructively owns within the meaning of Section 318 of the Code (as modified by Section 302(c) of the Code). Under the constructive ownership rules of Section 318 of the Code, a shareholder will be considered to own those Shares owned, directly or indirectly, by certain members of the shareholder’s family and certain entities (such as corporations, partnerships, trusts and estates) in which the shareholder has an equity interest, as well as Shares the shareholder has an option to purchase.

          One of the following tests must be satisfied with respect to the United States Holder in order for the exchange of Shares for cash to be treated as a sale or exchange by that shareholder for federal income tax purposes. Due to the factual nature of these tests, shareholders should consult their tax advisers to determine whether the purchase of their Shares in the Offer qualifies for sale or exchange treatment in their particular circumstances.

          Satisfaction of the “complete termination” and “substantially disproportionate” exceptions is dependent upon compliance with the objective tests set forth in Section 302(b)(3) and Section 302(b)(2) of the Code, respectively. A distribution to a shareholder will result in a “complete termination” of the

43

shareholder’s equity interest in us if either (1) all of the Shares actually and constructively owned by the shareholder are exchanged pursuant to the Offer or (2) all of the Shares actually owned by the shareholder are exchanged pursuant to the Offer and the shareholder is eligible to waive, and effectively waives, the attribution of Shares constructively owned by the shareholder in accordance with the procedures described in Section 302(c)(2) of the Code. United States Holders wishing to satisfy the “complete termination” test through waiver of attribution in accordance with the procedures described in Section 302(c)(2) of the Code should consult their tax advisors concerning the mechanics and desirability of such a waiver. A distribution to a shareholder will be “substantially disproportionate” if the percentage of the outstanding Shares actually and constructively owned by the shareholder immediately following the exchange of Shares pursuant to the Offer is less than 80% of the percentage of the outstanding Shares actually and constructively owned by the shareholder immediately before the exchange (treating as outstanding all Shares purchased in the Offer from the particular shareholder and all other shareholders).

          A distribution to a shareholder is “not essentially equivalent to a dividend” if it results in a “meaningful reduction” in the shareholder’s stock interest in us. Whether a shareholder meets this test will depend on the shareholder’s particular facts and circumstances. The IRS has indicated that even a small reduction in the percentage interest of a shareholder whose relative stock interest in a publicly held corporation is minimal and who exercises no control over corporate affairs should constitute a “meaningful reduction.” Shareholders should consult their tax advisers as to the application of this test to their particular circumstances.

          Contemporaneous dispositions or acquisitions of Shares by a shareholder or related individuals or entities may be deemed to be part of a single integrated transaction and may be taken into account in determining whether any of the three tests under Section 302(b) of the Code has been satisfied. Each shareholder should be aware that because proration may occur in the Offer, even if all the Shares actually and constructively owned by a shareholder are tendered pursuant to the Offer, fewer than all of such Shares may be purchased by us. Thus, proration may affect whether the surrender by a shareholder pursuant to the Offer will meet any of the three tests under Section 302 of the Code.

          In consulting with their tax advisors, shareholders should consider the advisability of conditioning the purchase of their tendered Shares upon our purchase of all or a sufficient number of Shares actually or constructively owned by such holder if necessary to produce the desired tax treatment.

          If a United States Holder’s receipt of cash attributable to an exchange of shares for cash pursuant to the Offer does not meet one of the tests of Section 302 of the Code described above, then the full amount of cash received by the United States Holder with respect to our purchase of Shares under the Offer will be treated as a distribution to the United States Holder with respect the United States Holder’s Shares and will be treated as ordinary dividend income to the United States Holder to the extent of our current or accumulated earnings and profits as determined under U.S. federal income tax principles. Provided certain holding period requirements are satisfied, non-corporate United States Holders generally will be subject to U.S. federal income tax at a maximum rate of 15% with respect to such dividend income. To the extent that the amount of the distribution exceeds our current and accumulated earnings and profits, the excess first will be treated as a return of capital that will reduce the United States Holder’s adjusted tax basis in the Shares exchanged in the Offer. Any amount remaining after the United States Holder’s adjusted tax basis has been reduced to zero will be taxable to the United States Holder as capital gain. Any such gain will be long-term capital gain if the United States Holder has held the Shares for more than one year as of the date we are treated as purchasing the Shares in the Offer for U.S. federal income tax consequences. A dividend received by a corporate United States Holder may be (1) eligible for a dividends-received deduction (subject to applicable exceptions and limitations) and (2) subject to the “extraordinary dividend” provisions of Section 1059 of the Code. Corporate shareholders should consult their own tax advisors regarding (1) whether a dividends-received deduction will be available to them, and (2) the application of Section 1059 of the Code to the ownership and disposition of their Shares.

          Consequences to Non-United States Holders. See Section 3 with respect to the application of U.S. federal income tax withholding to payments made to Non-United States Holders.

44

          Gain realized by a Non-United States Holder on an exchange of Shares for cash pursuant to the Offer generally will not be subject to U.S. federal income tax if the sale is treated as a sale or exchange for tax purposes pursuant to the tests of Section 302 of the Code described above unless (1) such gain is effectively connected with the conduct by such Non-United States Holder of a trade or business in the United States (and, if a treaty applies, the gain is generally attributable to a United States permanent establishment maintained by such Non-United States Holder), (2) in the case of gain realized by a Non-United States Holder that is an individual, such Non-United States Holder is present in the United States for 183 days or more in the taxable year of the sale or redemption and certain other conditions are met or (3) our Shares constitute a United States real property interest and the Non-United States Holder held, actually or constructively, at any time during the five-year period preceding the exchange more than 5% of our Shares. Our Shares will constitute a United States real property interest with respect to a Non-United States Holder if we are or have been a “United States real property holding corporation” for U.S. federal income tax purposes at any time during the shorter of (i) the period during which the Non-United States Holder held Shares or (ii) the 5-year period ending on the date the Non-United States Holder exchanges Shares pursuant to the Offer. We believe that we are not and have not been a United States real property holding corporation at any time during the past five years and do not expect to become one before our shares are exchanged for cash pursuant to the Offer.

          If a Non-United States Holder does not satisfy any of the Section 302 tests explained above, the full amount received by the Non-United States Holder with respect to our purchase of Shares under the Offer will be treated as a distribution to the Non-United States Holder with respect to the Non-United States Holder’s Shares. The treatment, for U.S. federal income tax purposes, of such distribution as a dividend, a tax-free return of capital or as a capital gain from the sale of Shares will be determined in the manner described above (see “Certain U.S. Federal Income Tax Consequences — Consequences to United States Holders.”). To the extent that amounts received by a Non-United States Holder with respect to our purchase of Shares under the Offer are treated as dividends, such dividends will generally be subject to withholding of United States federal income tax at the rate of 30% or such lower rate as may be specified by an applicable income tax treaty, provided we have received proper certification of the application of such income tax treaty. Non-United States Holders should consult their tax advisors regarding their entitlement to benefits under an applicable income tax treaty and the manner of claiming the benefits of such treaty. A Non-United States Holder that is eligible for a reduced rate of U.S. federal withholding tax under an income tax treaty may obtain a refund or credit of any excess amounts withheld by filing an appropriate claim for a refund with the IRS. Amounts treated as dividends that are effectively connected with a Non-United States Holder’s conduct of a trade or business in the United States or, if provided in an applicable income tax treaty, dividends that are attributable to a permanent establishment in the United States, are not subject to the U.S. federal withholding tax, but generally are instead taxed in the manner applicable to U.S. persons, as described above. In that case, we will not have to withhold U.S. federal withholding tax if the Non-United States Holder complies with applicable certification and disclosure requirements. In addition, dividends received by a foreign corporation that are effectively connected with the conduct of a trade or business in the United States may be subject to a branch profits tax at a 30% rate, or a lower rate specified in an applicable income tax treaty.

          United States Federal Income Tax Backup Withholding. See Section 3 with respect to the U.S. federal income tax backup withholding requirements.

          U.S. Federal Income Tax Considerations for Holders of Employee Stock Purchase Plan Shares and HCA 401(k) Plan Shares

          Employee Stock Purchase Plan. If a participant in the Company’s Amended and Restated Employee Stock Purchase Plan (the “ESPP”) tenders and sells Shares in the Offer that were acquired under the ESPP, then the participant generally will be treated for U.S. federal income tax purposes as having received ordinary compensation income with respect to a portion of the proceeds he or she receives. The amount of such ordinary compensation income depends upon the price at which Shares are sold in the Offer and how long the Shares acquired under the ESPP were held by the participant prior to the date of purchase by us in the Offer. If the Shares tendered and sold are held by the participant for two years or

45

less from the date the option to acquire such Shares under the ESPP was granted (“Grant Date”), then the amount of ordinary compensation income will be an amount equal to the excess, if any, of the fair market value of the Shares on the date the Shares were acquired under the ESPP over the price that the participant paid for the Shares. If the Shares tendered and sold are held by the participant for more than two years from the Grant Date, then the amount of the ordinary compensation income will be an amount equal to the lesser of: (a) the excess, if any, of the fair market value of the Shares on the date of purchase by us in the Offer over the amount originally paid for such Shares, or (b) the excess, if any, of the fair market value of the Shares on the Grant Date over the exercise price per Share. The amount of ordinary compensation income that a participant recognizes upon tender of his or her shares under the ESPP will be subject to ordinary income and employment taxes and will be included on the participant’s year 2005 Form W-2.

          In addition to any amount recognized by a participant under the ESPP as ordinary compensation income as described above, the participant may recognize capital gain (or loss) or dividend income as a result of the tender and sale of Shares in the Offer. For a general summary of these consequences, please refer to the section captioned “Certain U.S. Federal Income Tax Consequences — Consequences to United States Holders.”

          HCA 401(k) Plan. The HCA 401(k) Plan is a tax exempt trust and, therefore, no income, gain or loss will be recognized by a participant upon the tender or sale of Shares credited to his or her account under the HCA 401(k) Plan. However, by instructing U.S. Trust to tender and sell equivalent Shares a participant may be giving up special tax consequences applicable to employer securities upon distribution of such Shares from the HCA 401(k) Plan. Please refer to the Letter to Participants in the HCA 401(k) Plan sent to HCA 401(k) Plan participants together with this Offer to Purchase for a description of these tax consequences.

          The tax discussion set forth above is included for general information only. You are urged to consult with your tax advisor to determine the particular tax consequences to you of the Offer, including the applicability and effect of state, local and foreign tax laws.

15. Extension Of The Offer; Termination; Amendment

          We expressly reserve the right, in our sole discretion, at any time and from time to time, and regardless of whether or not any of the events set forth in Section 7 have occurred or are deemed by us to have occurred, to extend the period of time the Offer is open and delay acceptance for payment of, and payment for, any Shares by giving oral or written notice of the extension to the Depositary and making a public announcement of the extension. We also expressly reserve the right, in our sole discretion, to terminate the Offer and reject for payment and not pay for any Shares not theretofor accepted for payment or paid for or, subject to applicable law, to postpone payment for Shares upon the occurrence of any of the conditions specified in Section 7 by giving oral or written notice of the termination or postponement to the Depositary and making a public announcement of the termination or postponement. Our reservation of the right to delay payment for Shares that we have accepted for payment is limited by Rule 13e-4(f)(5) under the Exchange Act, which requires that we must pay the consideration offered or return the Shares tendered promptly after termination or withdrawal of the Offer. Subject to compliance with applicable law, we further reserve the right, in our sole discretion, and regardless of whether any of the events set forth in Section 7 have occurred or are deemed by us to have occurred, to amend the Offer in any respect (including, without limitation, by decreasing or increasing the consideration offered in the Offer to holders of Shares or by decreasing or increasing the number of Shares being sought in the Offer). Amendments to the Offer may be made at any time and from time to time by public announcement of the amendment. In the case of an extension, the amendment must be issued no later than 9:00 a.m., New York City time, on the first business day after the last previously scheduled or announced Expiration Date. Any public announcement made pursuant to the Offer will be disseminated promptly to shareholders in a manner reasonably designed to inform shareholders of the change. Without limiting the manner in which we may choose to make a public announcement, except as required by applicable law (including Rule 13e-4(e)(3) under the Exchange Act), we will have no obligation to publish, advertise or otherwise communicate any public announcement other than by issuing a press release to the Dow Jones News

46

Service or comparable service. If we materially change the terms of the Offer or the information concerning the Offer, or if we waive a material condition of the Offer, we will extend the Offer to the extent required by Rules 13e-4(d)(2) and 13e-4(e)(3) under the Exchange Act. These rules provide that the minimum period during which an offer must remain open following material changes in the terms of the offer or information concerning the offer (other than a change in price or a change in percentage of securities sought) will depend on the facts and circumstances, including the relative materiality of the terms or information.

          If:

          (a) we increase or decrease the price to be paid for Shares, materially increase the Lead Dealer Manager’s fee or increase or decrease the number of Shares being sought in the Offer and, in the event of an increase in the number of Shares being sought, the increase exceeds 2% of the outstanding Shares of our common stock, and

          (b) the Offer is scheduled to expire at any time earlier than the expiration of a period ending on the tenth business day from, and including, the date that notice of an increase or decrease is first published, sent or given in the manner specified in this Section 15,

          then, in each case, the Offer will be extended until the expiration of a period of 10 business days from the date of notice of the increase or decrease. For purposes of the Offer, a “business day” means any day other than a Saturday, Sunday or Federal holiday and consists of the time period from 12:01 a.m. through 12:00 Midnight, New York City time.

16. Fees And Expenses

          We have retained Merrill Lynch & Co. to act as the Lead Dealer Manager in connection with the Offer. Merrill Lynch & Co. will receive, for these services, a reasonable and customary fee.

          We have retained Georgeson Shareholder Communications, Inc. to act as the Information Agent and National City Bank to act as the Depositary in connection with the Offer. The Information Agent may contact holders of Shares by mail, telephone, telegraph and personal interviews and may request brokers, dealers, commercial banks, trust companies and other nominee shareholders to forward materials relating to the Offer to beneficial owners. The Information Agent and the Depositary will each receive reasonable and customary compensation for their respective services, will be reimbursed by us for reasonable out-of-pocket expenses and will be indemnified against certain liabilities in connection with the Offer, including liabilities under the federal securities laws.

          We will not pay any fees or commissions to brokers, dealers or other persons (other than fees to the Lead Dealer Manager and the Information Agent as described above) for soliciting tenders of Shares pursuant to the Offer. Shareholders holding Shares through brokers, dealers, commercial banks, trust companies or other nominees are urged to consult such nominees to determine whether transaction costs may apply. We will, however, upon request, reimburse brokers, dealers, commercial banks and trust companies for customary mailing and handling expenses incurred by them in forwarding the Offer and related materials to the beneficial owners of Shares held by them as a nominee or in a fiduciary capacity. No broker, dealer, commercial bank or trust company has been authorized to act as our agent or the agent of the Lead Dealer Manager, the Dealer Manager, the Information Agent or the Depositary for purposes of the Offer. We will pay or cause to be paid all stock transfer taxes, if any, on our purchase of Shares except as otherwise provided in Instruction 8 in the Letter of Transmittal.

17. Miscellaneous

          We are not aware of any jurisdiction where the making of the Offer is not in compliance with applicable law. If we become aware of any jurisdiction where the making of the Offer or the acceptance of Shares pursuant to the Offer is not in compliance with any valid applicable law, we will make a good faith effort to comply with the applicable law. If, after a good faith effort, we cannot comply with the applicable law, the Offer will not be made to, nor will tenders be accepted from or on behalf of, the holders of Shares residing in that jurisdiction.

      The undersigned hereby tenders to HCA Inc., a Delaware corporation (the “Company”), the above described shares of the Company’s common stock, par value $0.01 per share (the “Shares”), at the price per Share indicated in this Letter of Transmittal, net to the seller in cash less any applicable withholding taxes, without interest, upon the terms and subject to the conditions set forth in the Company’s Offer to Purchase, dated October 14, 2005 (the “Offer to Purchase”), receipt of which is hereby acknowledged, and in this Letter of Transmittal (which together, as they may be amended or supplemented from time to time, constitute the “Offer”).

      Subject to and effective upon acceptance for payment of the Shares tendered hereby in accordance with the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of such extension or amendment), the undersigned hereby sells, assigns and transfers to, or upon the order of, the Company all right, title and interest in and to all of the Shares that are being tendered hereby, and orders the registration of all such Shares if tendered by book-entry transfer and hereby irrevocably constitutes and appoints the Depositary as the true and lawful agent and attorney-in-fact of the undersigned (with full knowledge that said Depositary also acts as the agent of the Company) with respect to such Shares with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to:

      (a) deliver certificate(s) for such Shares or transfer ownership of such Shares on the account books maintained by any of the Book-Entry Transfer Facilities, together in either such case with all accompanying evidences of transfer and authenticity, to, or upon the order of, the Company upon receipt by the Depositary, as the undersigned’s agent, of the aggregate Purchase Price with respect to such Shares;

This action could have the effect of decreasing the purchase price determined by the Company which may result in receiving a price as low as $43.00 per Share.

Conditional Tender

      A tendering shareholder may condition his or her tender of Shares upon the Company purchasing a specified minimum number of the Shares tendered by the tendering shareholder, all as described in Section 6 of the Offer to Purchase. Unless at least that minimum number of Shares indicated below is purchased by the Company from the tendering shareholder pursuant to the terms of the Offer, none of the Shares tendered by the tendering shareholder will be purchased. It is the tendering shareholder’s responsibility to calculate that minimum number of Shares that must be purchased from the tendering shareholder if any are purchased, and each shareholder is urged to consult his or her own tax advisor. Unless this box has been checked and a minimum specified, the tender will be deemed unconditional.

o The minimum number of Shares that must be purchased from the tendering shareholder, if any are purchased, is:                     Shares.

      If, because of proration, the minimum number of Shares designated will not be purchased, the Company may accept conditional tenders by random lot, if necessary. However, to be eligible for purchase by random lot, the tendering shareholder must have tendered all of his or her Shares and, if true, checked the following box:

o The tendered Shares represent all Shares held by the undersigned.

INSTRUCTIONS

FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

      1. Guarantee of Signatures. No signature guarantee is required if either: (a) this Letter of Transmittal is signed by the registered holder of the Shares (which term, for purposes of this document, shall include any participant in the Book-Entry Transfer Facility whose name appears on a security position listing as the owner of such Shares) exactly as the name of the registered holder appears on the certificate tendered with this Letter of Transmittal and payment and delivery are to be made directly to such owner unless such owner has completed either the box entitled “Special Payment Instructions” or “Special Delivery Instructions” above; or (b) such Shares are tendered for the account of a member in good standing of the Security Transfers Agents Medallion Program, the New York Stock Exchange Medallion Signature Guarantee Program or the Stock Exchange Medallion Program (each such entity, an “Eligible Institution”). In all other cases, an Eligible Institution must guarantee all signatures on this Letter of Transmittal. See Instruction 7.

      2. Delivery of Letter of Transmittal and Certificates; Guaranteed Delivery Procedures. This Letter of Transmittal is to be used only if certificates for Shares are delivered with it to the Depositary (or such certificates will be delivered pursuant to a Notice of Guaranteed Delivery previously sent to the Depositary) or if a tender for Shares is being made concurrently pursuant to the procedure for tender by book-entry transfer set forth in Section 3 of the Offer to Purchase. Certificates for all physically tendered Shares or confirmation of a book-entry transfer into the Depositary’s account at the Book-Entry Transfer Facility of Shares tendered electronically, together in each case with a properly completed and duly executed Letter of Transmittal or duly executed and manually signed facsimile of it, or an Agent’s Message, in the case of a book-entry transfer, and any other documents required by this Letter of Transmittal, should be mailed or delivered to the Depositary at the appropriate address set forth herein and must be delivered to the Depositary on or before the Expiration Date (as defined in the Offer to Purchase). Delivery of documents to the Book-Entry Transfer Facility does not constitute delivery to the Depositary.

      Shareholders whose certificates are not immediately available or who cannot deliver certificates for their Shares and all other required documents to the Depositary on or before the Expiration Date, or whose Shares cannot be delivered on a timely basis pursuant to the procedures for book-entry transfer, must, in any such case, tender their Shares by or through any Eligible Institution by properly completing and duly executing and delivering a Notice of Guaranteed Delivery (or facsimile of it) and by otherwise complying with the guaranteed delivery procedure set forth in Section 3 of the Offer to Purchase. Pursuant to such procedure, certificates for all physically tendered Shares or book-entry confirmations, as the case may be, as well as a properly completed and duly executed Letter of Transmittal (or facsimile of it), or an Agent’s Message, in the case of a book-entry transfer, and all other documents required by this Letter of Transmittal, must be received by the Depositary within three NYSE trading days after receipt by the Depositary of such Notice of Guaranteed Delivery, all as provided in Section 3 of the Offer to Purchase.

      The Notice of Guaranteed Delivery may be delivered by hand or transmitted by facsimile transmission or mail to the Depositary and must include a guarantee by an Eligible Institution in the form set forth in such Notice. For Shares to be tendered validly pursuant to the guaranteed delivery procedure, the Depositary must receive the Notice of Guaranteed Delivery on or before the Expiration Date.

      THE METHOD OF DELIVERY OF ALL DOCUMENTS, INCLUDING CERTIFICATES FOR SHARES, IS AT THE OPTION AND RISK OF THE TENDERING SHAREHOLDER. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY.

      The Company will not accept any alternative, conditional or contingent tenders, nor will it purchase any fractional Shares, except as expressly provided in the Offer to Purchase. All tendering shareholders, by execution of this Letter of Transmittal (or a facsimile of it), waive any right to receive any notice of the acceptance of their tender.

9

      3. Inadequate Space. If the space provided in the box captioned “Description of Shares Tendered” is inadequate, the certificate numbers and/or the number of Shares should be listed on a separate signed schedule and attached to this Letter of Transmittal.

      4. Partial Tenders and Unpurchased Shares. (Not applicable to shareholders who tender by book-entry transfer.) If fewer than all of the Shares evidenced by any certificate are to be tendered, fill in the number of Shares that are to be tendered in the column entitled “Number of Shares Tendered,” in the box captioned “Description of Shares Tendered.” In such case, if any tendered Shares are purchased, a new certificate for the remainder of the Shares (including any Shares not purchased) evidenced by the old certificate(s) will be issued and sent to the registered holder(s), unless otherwise specified in either the “Special Payment Instructions” or “Special Delivery Instructions” box on this Letter of Transmittal, as soon as practicable after the Expiration Date. Unless otherwise indicated, all Shares represented by the certificate(s) listed and delivered to the Depositary will be deemed to have been tendered.

      5. Indication of Price at Which Shares are Being Tendered. For Shares to be properly tendered at a minimum price per share, the shareholder MUST check the box indicating the price per Share at which such holder is tendering Shares under “Price (in Dollars) per Share at Which Shares are Being Tendered” on this Letter of Transmittal. CHECK ONE BOX ONLY. IF MORE THAN ONE BOX IS CHECKED OR IF NO BOX IS CHECKED, THERE IS NO PROPER TENDER OF SHARES. A shareholder wishing to tender portions of such holder’s Share holdings at different prices must complete a separate Letter of Transmittal for each price at which such holder wishes to tender each such portion of such holder’s Shares. The same Shares cannot be tendered (unless previously properly withdrawn as provided in Section 4 of the Offer to Purchase) at more than one price. For Shares to be properly tendered at a price per Share determined pursuant to the Offer, the shareholder MUST check the box under the heading “Shares Tendered at Price Determined Pursuant to the Offer.”

      6. Conditional Tender. As described in Sections 1 and 6 of the Offer to Purchase, shareholders may condition their tenders on all or a minimum number of their tendered Shares being purchased.

      To make a conditional tender, a shareholder must indicate this in the box captioned “Conditional Tender” in this Letter of Transmittal or, if applicable, the Notice of Guaranteed Delivery. In the box in this Letter of Transmittal or the Notice of Guaranteed Delivery, a shareholder must calculate and appropriately indicate the minimum number of Shares that must be purchased from the tendering shareholder if any are to be purchased.

      As discussed in Sections 1 and 6 of the Offer to Purchase, proration may affect whether the Company accepts conditional tenders and may result in Shares tendered pursuant to a conditional tender at or below the Purchase Price not being purchased if the minimum number of Shares would not be purchased. If, because of proration, the minimum number of Shares designated will not be purchased, the Company may accept conditional tenders by random lot, if necessary. However, to be eligible for purchase by random lot, a shareholder must have tendered all his or her Shares and checked the box so indicating. Upon the selection by lot, if any, the Company will limit its purchase in each case to the designated minimum number of Shares.

      All tendered Shares will be deemed unconditionally tendered unless the “Conditional Tender” box is completed.

      7. Signatures on Letter of Transmittal, Stock Powers and Endorsements.

      (a) If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, the signature(s) must correspond exactly with the name(s) as written on the face of the certificate(s) without any change whatsoever;

      (b) If the Shares are registered in the names of two or more joint holders, each such holder must sign this Letter of Transmittal;

10

      (c) If any tendered Shares are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate Letters of Transmittal (or facsimiles of it) as there are different registrations of certificates;

      (d) When this Letter of Transmittal is signed by the registered holder(s) of the Shares listed and transmitted hereby, no endorsement(s) of certificate(s) representing such Shares or separate stock power(s) are required unless payment is to be made or the certificate(s) for Shares not tendered or not purchased are to be issued to a person other than the registered holder(s). Signature(s) on such certificate(s) must be guaranteed by an Eligible Institution. If this Letter of Transmittal is signed by a person other than the registered holder(s) of the certificate(s) listed, or if payment is to be made or their certificate(s) for Shares not tendered or not purchased are to be issued to a person other than the registered holder(s), the certificate(s) must be endorsed or accompanied by appropriate stock power(s), in either case signed exactly as the name(s) of the registered holder(s) appears on the certificate(s), and the signature(s) on such certificate(s) or stock power(s) must be guaranteed by an Eligible Institution. See Instruction 1; and

      (e) If this Letter of Transmittal or any certificate(s) or stock power(s) are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing and must submit proper evidence satisfactory to the Company of their authority so to act.

      8. Stock Transfer Taxes. Except as provided in this Instruction 8, no stock transfer tax stamps or funds to cover such stamps need accompany this Letter of Transmittal. The Company will pay any stock transfer taxes payable on the transfer to it of Shares purchased pursuant to the Offer. If, however:

      (a) Payment of the Purchase Price for Shares tendered hereby and accepted for purchase is to be made to any person other than the registered holder(s);

      (b) Shares not tendered or not accepted for purchase are to be registered in the name(s) of any person(s) other than the registered holder(s); or

      (c) Tendered certificates are registered in the name(s) of any person(s) other than the person(s) signing this Letter of Transmittal;

then the Depositary will deduct from such Purchase Price the amount of any stock transfer taxes (whether imposed on the registered holder, such other person or otherwise) payable on account of the transfer to such person, unless satisfactory evidence of the payment of such taxes or any exemption therefrom is submitted.

      9. Odd Lots. As described in Section 1 of the Offer to Purchase, if the Company is to purchase fewer than all Shares tendered on or before the Expiration Date and not properly withdrawn, the Shares purchased first will consist of all Shares properly tendered by any shareholder who owns beneficially or of record an aggregate of fewer than 100 Shares (not including any shares held in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan), and who tenders all of such holder’s Shares at or below the Purchase Price (an “Odd Lot Holder”). This preference will not be available unless the box captioned “Odd Lots” is completed.

      10. Special Payment and Delivery Instructions. If certificate(s) for Shares not tendered or not purchased and/or check(s) are to be issued in the name of a person other than the signer of the Letter of Transmittal or if such certificates and/or checks are to be sent to someone other than the person signing the Letter of Transmittal or to the signer at a different address, the boxes captioned “Special Payment Instructions” and/or “Special Delivery Instructions” on this Letter of Transmittal should be completed as applicable and signatures must be guaranteed as described in Instruction 1.

      11. Irregularities. All questions as to the number of Shares to be accepted, the price to be paid therefor and the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by the Company in its sole discretion, which determinations shall be final and binding on all parties. The Company reserves the absolute right to reject any or all tenders of

11

Shares it determines not to be in proper form or the acceptance of which or payment for which may, in the opinion of the Company’s counsel, be unlawful. The Company also reserves the absolute right to waive any defect or irregularity in any tender with respect to any particular Shares or any particular shareholder, and the Company’s interpretation of the terms of the Offer (including these instructions) will be final and binding on all parties. No tender of Shares will be deemed to be properly made until all defects and irregularities have been cured by the tendering shareholder or waived by the Company. Unless waived, any defects or irregularities in connection with tenders must be cured within such time as the Company shall determine. None of the Company, the Lead Dealer Manager (as defined in the Offer to Purchase), the Dealer Manager (as defined in the Offer to Purchase), the Depositary, the Information Agent (as defined in the Offer to Purchase) or any other person is or will be obligated to give notice of any defects or irregularities in tenders and none of them will incur any liability for failure to give any such notice.

      12. Questions and Requests for Assistance and Additional Copies. Questions and requests for assistance may be directed to the Information Agent or the Lead Dealer Manager at their addresses and telephone numbers set forth at the end of this Letter of Transmittal. Requests for additional copies of the Offer to Purchase, the Notice of Guaranteed Delivery and this Letter of Transmittal may be obtained from the Information Agent at the address and telephone number set forth at the end of this Letter of Transmittal or from your broker, dealer, commercial bank, trust company or other nominee.

      13. Substitute Form W-9 and Form W-8. Under the U.S. federal income tax backup withholding rules, unless an exemption applies under applicable law and regulations, 28% of the gross proceeds payable to a shareholder or other payee pursuant to the Offer must be withheld and remitted to the U.S. Internal Revenue Service (“IRS”), unless the shareholder or other payee provides its taxpayer identification number (employer identification number or social security number) to the Depositary (as payor) and certifies under penalty of perjury that such number is correct. Therefore, each tendering shareholder should complete and sign the Substitute Form W-9 included as part of this Letter of Transmittal so as to provide the information and certification necessary to avoid backup withholding, unless such shareholder otherwise establishes to the satisfaction of the Depositary that it is not subject to backup withholding. If the Depositary is not provided with the correct taxpayer identification number (“TIN”), the tendering shareholder also may be subject to a penalty imposed by the IRS. The box in part 3 of the form should be checked if the tendering shareholder has not been issued a TIN and has applied for a TIN or intends to apply for a TIN in the near future. If the box in Part 3 is checked and the Depositary is not provided with a TIN prior to the payment of the Purchase Price, the Depositary will withhold 28% on all such payments of the Purchase Price. If withholding results in an overpayment of taxes, a refund may be obtained. Certain “exempt recipients” (including, among others, all corporations and certain Non-United States Holders (as defined below)) are not subject to these backup withholding and information reporting requirements. In order for a Non-United States Holder to qualify as an exempt recipient, that shareholder must submit an IRS Form W-8BEN (or successor form), signed under penalties of perjury, attesting to that shareholder’s exempt status. Such statement can be obtained from the Depositary.

      14. Withholding on Non-United States Holders. Even if a Non-United States Holder has provided the required certification to avoid backup withholding, the Depositary will withhold U.S. federal income taxes equal to 30% of the gross payments payable to a Non-United States Holder or his agent unless the Depositary determines that a reduced rate of withholding is available pursuant to a tax treaty or that an exemption from withholding is applicable because such gross proceeds are effectively connected with the conduct of a trade or business within the United States. In general, a “Non-United States Holder” is any shareholder that for U.S. federal income tax purposes is not (i) a citizen or resident of the United States, (ii) a corporation created or organized in or under the laws of the United States or any State or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of the source of such income or (iv) a trust (a) if a court within the United States is able to exercise primary supervision over the administration of the trust and (b) one or more U.S. persons have the authority to control all substantial decisions of the trust. In order to obtain a reduced rate of withholding pursuant to a tax treaty, a Non-United States Holder must deliver to the Depositary before payment a properly completed and executed IRS Form W-8BEN (or successor form). In order to

12

obtain an exemption from withholding on the grounds that the gross proceeds paid pursuant to the Offer are effectively connected with the conduct of a trade or business within the United States, a Non-United States Holder must deliver to the Depositary a properly completed and executed IRS Form W-8ECI (or successor form). The Depositary will determine a shareholder’s status as a Non-United States Holder and eligibility for a reduced rate of, or an exemption from, withholding by reference to outstanding, valid certificates or statements concerning eligibility for a reduced rate of, or exemption from, withholding (e.g., IRS Form W-8BEN (or successor form) or IRS Form W-8ECI (or successor form)) unless facts and circumstances indicate that such reliance is not warranted. A Non-United States Holder may be eligible to obtain a refund of all or a portion of any tax withheld if such Non-United States Holder meets the “complete termination,” “substantially disproportionate” or “not essentially equivalent to a dividend” test described in Section 14 of the Offer to Purchase or is otherwise able to establish that no tax or a reduced amount of tax is due. Non-United States Holders are urged to consult their own tax advisors regarding the application of U.S. federal income tax withholding, including eligibility for a withholding tax reduction or exemption, and the refund procedure.

      15. Lost, Destroyed or Stolen Certificates. If any certificate(s) representing Shares has been lost, destroyed or stolen, the shareholder should promptly notify the Depositary by checking the box immediately following the box entitled “Description of Shares Tendered” and indicating the number of Shares so lost, destroyed or stolen. The shareholder will then be instructed by the transfer agent as to the steps that must be taken in order to replace the certificate. This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost, destroyed or stolen certificates have been followed.

Resident alien individuals:

If you are a resident alien individual and you do not have, and are not eligible to get, a Social Security number, your taxpayer identification number is your individual taxpayer identification number (“ITIN”) as issued by the Internal Revenue Service (“IRS”). Enter it on the portion of the Substitute Form W-9 where the Social Security number would otherwise be entered. If you do not have an ITIN, see “Obtaining a Number” below.

Name:

If you are an individual, generally provide the name shown on your social security card. However, if you have changed your last name, for instance, due to marriage, without informing the Social Security Administration of the name change, please enter your first name and both the last name shown on your social security card and your new last name.

Obtaining a Number:

If you do not have a taxpayer identification number, obtain IRS Form SS-5, Application for a Social Security Card (for individuals), or IRS Form SS-4, Application for Employer Identification Number (for businesses and all other entities), at the local office of the Social Security Administration or the IRS and apply for a number. Resident alien individuals who are not eligible to get a Social Security number and need an ITIN should obtain IRS Form W-7, Application for IRS Individual Taxpayer Identification Number, from the IRS.

Payees and Payments Exempt from Backup Withholding:

The following is a list of payees exempt from backup withholding and for which no information reporting is required. For interest and dividends, all listed payees are exempt except the payee in item (9). For broker transactions, payees listed in items (1) through (13) and a person registered under the Investment Advisers Act of 1940 who regularly acts as a broker are exempt. For barter exchange transactions and patronage dividends, payees listed in (1) through (5) are exempt. Payments subject to reporting under sections 6041 and 6041A are generally exempt from backup withholding only if made to payees described in items (1) through (7). Unless otherwise indicated, all “section” references are to sections of the Internal Revenue Code of 1986, as amended (the “Code”).

(1)	An organization exempt from tax under section 501(a), or an IRA, or a custodial account under section 403(b)(7) if the account satisfies the requirements of section 401(f)(2).

Payments of dividends and patronage dividends not generally subject to backup withholding include the following:

•  Payments to nonresident aliens subject to withholding under section 1441.

•  Payments to partnerships not engaged in a trade or business in the U.S. and which have at least one nonresident partner.

•  Payments of patronage dividends where the amount received is not paid in money.

•  Payments made by certain foreign organizations.

•  Section 404(k) distributions made by an ESOP.

Payments of interest not generally subject to backup withholding include the following:

•  Payments of interest on obligations issued by individuals. Note: You may be subject to backup withholding if this interest is $600 or more and is paid in the course of your trade or business and you have not provided your correct taxpayer identification number to the payor.

•  Payments of tax-exempt interest (including exempt-interest dividends under section 852).

•  Payments described in section 6049(b)(5) to non-resident aliens.

•  Payments on tax-free covenant bonds under section 1451.

•  Payments made by certain foreign organizations.

•  Payments of mortgage or student loan interest to you.

Exempt payees described above should file Substitute Form W-9 to avoid possible erroneous backup withholding. File this form with the Payor; furnish your taxpayer identification number; indicate that you are exempt on the face of the form, sign and date the form and return it to the Payor. If you are a non-resident alien or a foreign entity not subject to backup withholding, file with Payor the appropriate completed IRS Form W-8 (or successor form).

   Certain payments other than interest, dividends and patronage dividends, that are not subject to information reporting are also not subject to backup withholding. For details, see Sections 6041, 6041A, 6042, 6044, 6045, 6049, 6050A and 6050N of the Code and the Treasury regulations promulgated thereunder.

   Privacy Act Notice— Section 6109 requires most recipients of dividend, interest, or other payments to give their correct taxpayer identification numbers to payors who must report the payments to the IRS. The IRS uses the numbers for identification purposes and to verify the accuracy of tax returns. The IRS also may provide this information to the Department of Justice for civil and criminal litigation and to cities, states, and the District of Columbia to carry out their tax laws. The IRS may also disclose this information to other countries under a tax treaty, or to Federal and state agencies to enforce Federal nontax criminal laws and to combat terrorism. Payors must be given the numbers whether or not recipients are required to file tax returns. Payors must generally withhold tax from payments of taxable interest, dividend, and certain other payments to a payee who does not furnish a taxpayer identification number to a payor. The current rate of such withholding tax is 28%. Certain penalties may also apply.

Penalties

(1) Penalty for failure to furnish taxpayer identification number— If you fail to furnish your correct taxpayer identification number to a payor, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

(2) Civil Penalty for false information with respect to withholding— If you make a false statement with no reasonable basis which results in no imposition of backup withholding, you are subject to a penalty of $500.

(3) Criminal Penalty for falsifying information— Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

Odd Lots

      To be completed only if the Shares are being tendered by or on behalf of a person who owns beneficially or of record, an aggregate of fewer than 100 Shares. The undersigned either (check one box):

o  is the beneficial or record owner of an aggregate of fewer than 100 Shares, all of which are being tendered; or

o  is a broker dealer, commercial bank, trust company, or other nominee that (a) is tendering for the beneficial owner(s) thereof, Shares with respect to which it is record holder and (b) believes, based upon representations made to it by such beneficial owner(s), that each such person is the beneficial or record owner of an aggregate of fewer than 100 Shares and is tendering all of such Shares.

Unless at least that minimum number of Shares indicated below is purchased from the tendering shareholder by the Company pursuant to the terms of the Offer, none of the Shares tendered by the tendering shareholder will be purchased. It is the tendering shareholder’s responsibility to calculate that minimum number of Shares that must be purchased from the tendering shareholder if any are purchased, and each shareholder is urged to consult his or her own tax advisor. Unless this box has been checked and a minimum specified, the tender will be deemed unconditional.

o  The minimum number of Shares that must be purchased from the tendering shareholder, if any are purchased, is:                      Shares.

      If, because of proration, the minimum number of Shares designated will not be purchased, the Company may accept conditional tenders by random lot, if necessary.

o  The tendered Shares represent all Shares held by the undersigned.

Shares Tendered at Price Determined Pursuant to the Offer

o  I want to maximize the chance of having the Company accept for purchase all of the Shares I am tendering (subject to the possibility of proration). Accordingly, by checking this one box instead of one of the price boxes below, I hereby tender Shares at, and am willing to accept, the Purchase Price resulting from the Offer process. This action could result in receiving a price as low as $43.00 per Share.

Offer to Purchase for Cash

Up to 50,000,000 Shares of its Common Stock

at a Purchase Price not greater than $50.00

nor less than $43.00 per Share

THE OFFER, WITHDRAWAL RIGHTS AND PRORATION PERIOD WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON MONDAY, NOVEMBER 14, 2005, UNLESS THE OFFER IS EXTENDED.

October 14, 2005

To Our Clients:

      Enclosed for your consideration are the Offer to Purchase, dated October 14, 2005, and the related Letter of Transmittal (which together, as they may be amended or supplemented from time to time, constitute the “Offer”) in connection with the Offer by HCA Inc., a Delaware corporation (the “Company”), to purchase 50,000,000 shares (or such lesser number of shares as are properly tendered and not properly withdrawn) of its common stock, par value $0.01 per share (the “Shares”), at a price not greater than $50.00 nor less than $43.00 per Share net to the seller in cash less any applicable withholding taxes, without interest, upon the terms and subject to the conditions set forth in the Offer.

      The Company will determine the price per Share, not greater than $50.00 nor less than $43.00 per Share, net to the seller in cash (the “Purchase Price”), that it will pay for Shares properly tendered pursuant to the Offer, taking into account the number of Shares so tendered and the prices specified by tendering shareholders. The Company will select the lowest Purchase Price that will allow it to buy 50,000,000 Shares (or such lesser number of Shares as are properly tendered at prices not greater than $50.00 nor less than $43.00 per Share). All Shares properly tendered on or before the Expiration Date at prices at or below the Purchase Price and not properly withdrawn will be purchased at the Purchase Price, upon the terms and subject to the conditions of the Offer, including the odd lot, proration and conditional tender provisions of the Offer. All Shares acquired in the Offer will be acquired at the same Purchase Price. Shares tendered at prices greater than the Purchase Price and Shares not purchased because of proration and conditional tenders will be returned at the Company’s expense to the shareholders who tendered such Shares. The Company reserves the right, in its sole discretion, to purchase more than 50,000,000 Shares pursuant to the Offer. See Sections 1 and 15 of the Offer to Purchase.

      If the number of Shares validly tendered and not properly withdrawn on or before the Expiration Date is less than or equal to 50,000,000 Shares (or such greater number of Shares as the Company may elect to purchase pursuant to the Offer), the Company will, upon the terms and subject to the conditions of the Offer, purchase at the Purchase Price all Shares so tendered.

      THE BOARD OF DIRECTORS OF THE COMPANY HAS APPROVED THE OFFER. HOWEVER, NEITHER THE COMPANY NOR ITS BOARD OF DIRECTORS, THE LEAD DEALER MANAGER, THE DEALER MANAGER, THE INFORMATION AGENT OR THE DEPOSITARY ARE MAKING ANY RECOMMENDATION TO SHAREHOLDERS AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING THEIR SHARES. EACH SHAREHOLDER MUST MAKE THE DECISION WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES AND AT WHAT PRICE OR PRICES SHARES SHOULD BE TENDERED. OUR DIRECTORS AND OFFICERS HAVE ADVISED US THAT THEY DO NOT INTEND TO TENDER SHARES PURSUANT TO THE OFFER.

      We are the owner of record of Shares held for your account. As such, we are the only ones who can tender your Shares, and then only pursuant to your instructions. We are sending you the Letter of Transmittal for your information only; you cannot use it to tender Shares we hold for your account.

      Please instruct us as to whether you wish us to tender any or all of the Shares we hold for your account on the terms and subject to the conditions of the Offer.

      We call your attention to the following:

      1. You may tender Shares at prices not greater than $50.00 nor less than $43.00 per Share as indicated in the attached Instruction Form, net to you in cash.

      2. The Offer is not conditioned on any minimum number of Shares being tendered. However, the Offer is subject to other conditions described in the Offer to Purchase, including amending the Company’s existing credit facility or refinancing it pursuant to the terms and conditions contained in the Refinancing Commitment Letter (as defined in the Offer to Purchase) and obtaining the necessary financing for the Offer pursuant to the terms and conditions contained in the Term Facility Commitment Letter (as defined in the Offer to Purchase).

      3. The Offer, withdrawal rights and proration period will expire at 5:00 p.m., New York City time, on Monday, November 14, 2005, unless the Company extends the Offer.

      4. The Offer is for 50,000,000 Shares, constituting approximately 11.0% of the Shares outstanding as of September 30, 2005.

      5. Tendering shareholders who are registered holders will not be obligated to pay any brokerage commissions or solicitation fees to the Lead Dealer Manager, the Dealer Manager, the Depositary, the Information Agent or the Company or, subject to Instruction 8 of the Letter of Transmittal, stock transfer taxes on the Company’s purchase of Shares pursuant to the Offer.

      6. If you hold beneficially or of record an aggregate of fewer than 100 Shares, and you instruct us to tender on your behalf all such Shares at or below the Purchase Price before the Expiration Date and check the box captioned “Odd Lots” in the attached Instruction Form, the Company, upon the terms and subject to the conditions of the Offer, will accept all such Shares for purchase before proration, if any, of the purchase of other Shares properly tendered at or below the Purchase Price.

      7. If you wish to condition your tender upon the purchase of all Shares tendered or upon the Company’s purchase of a specified minimum number of the Shares which you tender, you may elect to do so and thereby avoid possible proration of your tender. If, because of proration, the minimum number of Shares designated will not be purchased, the Company may accept conditional tenders by random lot, if necessary. To elect such a condition complete the section below captioned “Conditional Tender.”

      8. If you wish to tender portions of your Shares at different prices, you must complete a separate Instruction Form for each price at which you wish to tender each such portion of your Shares. We must submit separate Letters of Transmittal on your behalf for each such price you will accept for each such portion tendered.

      If you wish to have us tender any or all of your Shares, please so instruct us by completing, executing, detaching and returning to us the attached Instruction Form. An envelope to return your Instruction Form to us is enclosed. If you authorize us to tender your Shares, we will tender all such Shares unless you specify otherwise on the attached Instruction Form.

      YOUR INSTRUCTION FORM SHOULD BE FORWARDED TO US IN AMPLE TIME TO PERMIT US TO SUBMIT A TENDER ON YOUR BEHALF ON OR BEFORE THE EXPIRATION DATE OF THE OFFER. THE OFFER, WITHDRAWAL RIGHTS AND PRORATION PERIOD WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON MONDAY, NOVEMBER 14, 2005, UNLESS THE COMPANY EXTENDS THE OFFER.

      As described in Section 1 of the Offer to Purchase, if more than 50,000,000 Shares (or such greater number of Shares as the Company may elect to purchase) have been properly tendered at or below the Purchase Price and not

2

properly withdrawn prior to the Expiration Date, the Company will purchase tendered Shares on the basis set forth below:

•  First, the Company will purchase all Shares tendered by any Odd Lot Holder who:

      (1) tenders all Shares owned beneficially or of record by the Odd Lot Holder at a price at or below the Purchase Price selected by the Company (tenders of less than all of the Shares owned by the Odd Lot Holder will not qualify for this preference); and

      (2) completes the section entitled “Odd Lots” in the Letter of Transmittal and, if applicable, in the Notice of Guaranteed Delivery.

•  Second, after the purchase of all of the Shares properly tendered by Odd Lot Holders, subject to the conditional tender provisions described in Section 6 in the Offer to Purchase, the Company will purchase all other Shares tendered at prices at or below the Purchase Price on a pro rata basis, with appropriate adjustments to avoid purchases of fractional Shares, determined by dividing the remaining number of Shares to be purchased by the Company in the Offer by the number of all Shares tendered (other than by Odd Lot Holders given priority as described above); and

•  Third, if necessary to permit the Company to purchase 50,000,000 Shares, Shares conditionally tendered (for which the condition was not initially satisfied) at or below the Purchase Price selected by the Company and not properly withdrawn prior to the Expiration Date, will, to the extent feasible, be selected for purchase by random lot. To be eligible for purchase by random lot, shareholders whose Shares are conditionally tendered must have tendered all of their Shares.

      The Offer is being made to all holders of Shares. The Offer is not being made to, nor will tenders be accepted from or on behalf of, holders of Shares of common stock of the Company residing in any jurisdiction in which the making of the Offer or acceptance thereof would not be in compliance with the laws of that jurisdiction.

Unless this box has been checked and a minimum specified, the tender will be deemed unconditional.

Offer to Purchase for Cash

Up to 50,000,000 Shares of its Common Stock

at a Purchase Price not greater than $50.00

nor less than $43.00 per Share

THE OFFER, WITHDRAWAL RIGHTS AND PRORATION PERIOD WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON MONDAY, NOVEMBER 14, 2005, UNLESS THE OFFER IS EXTENDED.

To Participants in the Amended and Restated HCA Employee Stock Purchase Plan:

      HCA Inc. (the “Company”) has announced an offer to purchase for cash up to 50,000,000 shares (or such lesser number of shares as are properly tendered and not properly withdrawn) of its common stock, $0.01 par value per share (the “Shares”), at a price not greater than $50.00 nor less than $43.00 per Share, net to the seller in cash less any applicable withholding taxes, without interest (the “Offer”). The Offer is being made upon the terms and subject to the conditions set forth in the Offer to Purchase and the related Letter of Transmittal, which are enclosed, as amended or supplemented from time to time. As a participant in the Amended and Restated HCA Employee Stock Purchase Plan (the “Employee Stock Purchase Plan”), you may tender Shares that are held in your Employee Stock Purchase Plan account at Computershare Trust Co., Inc. (the “ESPP Plan Administrator”).

      If you do not wish to tender any portion of the Shares in your Employee Stock Purchase Plan account, you do not need to take any action. If you would like to tender some or all of the Shares held in your Employee Stock Purchase Plan account in response to the Offer, you must follow the instructions set forth below.

      The Offer. The Company will select the lowest purchase price (the “Purchase Price”) that will allow it to purchase 50,000,000 Shares, or such lesser number of Shares as are properly tendered and not properly withdrawn pursuant to the Offer. The Company will pay the same Purchase Price for all Shares purchased in the Offer. All Shares properly tendered at prices at or below the Purchase Price and not properly withdrawn will be purchased, subject to the conditions of the Offer and the “odd lot,” proration and conditional tender provisions described in the Offer to Purchase.

      If more than the number of Shares the Company seeks are properly tendered prior to 5:00 p.m., New York City time, on Monday, November 14, 2005, unless the Company, in its sole discretion, shall have extended the period of time during which Offer will remain open (the latest time and date at which the Offer shall expire is the “Expiration Date”), the Company will buy Shares first from all of the Company’s holders of “odd lots” of less than 100 Shares (not including any Shares held in the Employee Stock Purchase Plan or the HCA 401(k) Plan, which will not have priority) who properly tender all of their Shares at or below the Purchase Price selected by the Company. Second, after purchasing all Shares from the “odd lot” holders, the Company will purchase Shares from all other shareholders (including participants in the Employee Stock Purchase Plan and the HCA 401(k) Plan) who properly tender Shares at or below the Purchase Price selected by the Company, on a pro rata basis, subject to the conditional tender provisions described in Section 6 of the Offer to Purchase. Third, if necessary to permit the Company to purchase 50,000,000 Shares, Shares conditionally tendered (for which the condition was not initially satisfied) at or below the Purchase Price will, to the extent feasible, be selected for purchase by random lot. To be eligible for purchase by random lot, shareholders whose Shares are conditionally tendered must have tendered all of their Shares. See Sections 1 and 6 of the Offer to Purchase.

      Shares tendered at prices greater than the purchase price that is determined by the Company and Shares not purchased because of proration or conditional tenders will be returned promptly following the expiration of the Offer.

The Company reserves the right, in its sole discretion, to purchase more than 50,000,000 Shares pursuant to the Offer, subject to compliance with applicable law.

      Because the terms and conditions of the Letter of Transmittal will govern the tender of the Shares held in accounts under the Employee Stock Purchase Plan, you should read the Letter of Transmittal carefully. The Letter of Transmittal, however, is furnished to you for your information only and cannot be used by you to tender Shares that are held in your Employee Stock Purchase Plan account. If you hold Shares outside of the Employee Stock Purchase Plan and wish to tender those Shares as well as Shares held in your Employee Stock Purchase Plan account, you must comply with the procedures described in the Letter of Transmittal and the Offer to Purchase for your Shares outside of the Employee Stock Purchase Plan, and submit an Instruction Form for Shares you hold in your Employee Stock Purchase Plan account. You must use the attached Instruction Form to properly tender Shares that are held in your Employee Stock Purchase Plan account. You should also read the Offer to Purchase carefully before making any decision regarding the Offer.

      Tendering Shares. To instruct the ESPP Plan Administrator to tender any or all of the Shares held in your Employee Stock Purchase Plan account, you must complete the Instruction Form set forth below and return it to the ESPP Plan Administrator.

      Please note the following:

      1. We have been advised that if the ESPP Plan Administrator has not received your Instruction Form at least three business days before the expiration of the Offer, the ESPP Plan Administrator will not tender any Shares held in your Employee Stock Purchase Plan account. The Offer, withdrawal rights and proration period will expire at 5:00 p.m., New York City time, on Monday, November 14, 2005, unless the expiration date of the Offer is extended. Consequently, your Instruction Form must be received by the ESPP Plan Administrator no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005, unless the Offer is extended by the Company.

      2. Shares held in your Employee Stock Purchase Plan account may be tendered at prices not greater than $50.00 nor less than $43.00 per Share.

      3. The Offer is for up to 50,000,000 Shares, constituting approximately 11.0% of the outstanding Shares of the Company as of September 30, 2005. The Offer is not conditioned on any minimum number of Shares being tendered. However, the Offer is subject to other conditions described in the Offer to Purchase, including amending the Company’s existing credit facility or refinancing it pursuant to the terms and conditions contained in the Refinancing Commitment Letter (as defined in the Offer to Purchase) and obtaining the necessary financing for the Offer pursuant to the terms and conditions contained in the Term Facility Commitment Letter (as defined in the Offer to Purchase).

      4. The Company’s Board of Directors has approved the making of the Offer. However, neither the Company nor the Company’s Board of Directors nor the ESPP Plan Administrator is making any recommendation whether you should tender or refrain from tendering your Shares or at what purchase price you should choose to tender your Shares. You must make your own decision as to whether to tender your Shares and, if so, how many Shares to tender and the price or prices at which you will tender them. The Company’s directors and executive officers have informed the Company that they do not intend to tender Shares pursuant to the Offer.

      5. Tendering shareholders will not be obligated to pay any brokerage fees or commissions or solicitation fees to tender their Shares held in their Employee Stock Purchase Plan account. Except as described in the Letter of Transmittal, tendering shareholders will not be obligated to pay any stock transfer taxes on the transfer of Shares pursuant to the Offer.

      6. As more fully described in the Offer to Purchase, tenders will be deemed irrevocable unless timely withdrawn. If you instruct the ESPP Plan Administrator to tender the Shares held in your Employee Stock Purchase Plan account, and you subsequently decide to change your instructions or withdraw your tender of Shares, you may do so by submitting a new Instruction Form. However, the new Instruction Form will be effective only if it is received by the ESPP Plan Administrator at the address listed below, on or before 5:00 p.m., New York City time, on Tuesday, November 8, 2005, three business days before the expiration of the

2

Offer, unless the Offer is extended. The Offer is scheduled to expire at 5:00 p.m., New York City time, on Monday, November 14, 2005. Upon receipt of a timely submitted, new Instruction Form, your previous Instruction Form to tender the Shares will be deemed canceled. If your new Instruction Form directed the ESPP Plan Administrator to withdraw from tender the Shares held in your Employee Stock Purchase Plan account, you may later re-tender those Shares by submitting a new Instruction Form so long as it is received by the ESPP Plan Administrator on or before three business days before the expiration of the Offer.

      7. If a participant in the Employee Stock Purchase Plan tenders and sells Shares in the Offer that were acquired under the Employee Stock Purchase Plan, then the participant generally will be treated for federal income tax purposes as having received ordinary compensation income with respect to a portion of the proceeds he or she receives. The amount of such ordinary compensation income depends upon the price at which Shares are sold in the Offer and how long the Shares acquired under the Employee Stock Purchase Plan were held by the participant prior to the date of purchase by us in the Offer. If the Shares tendered and sold are held by the participant for two years or less from the date the option to acquire such Shares under the Employee Stock Purchase Plan was granted (“Grant Date”), then the amount of ordinary compensation income will be an amount equal to the excess, if any, of the fair market value of the Shares on the date the Shares were acquired under the Employee Stock Purchase Plan over the price that the participant paid for the Shares. If the Shares tendered and sold are held by the participant for more than two years from the Grant Date, then the amount of the ordinary compensation income will be an amount equal to the lesser of: (a) the excess, if any, of the fair market value of the Shares on the date of purchase by us in the Offer over the amount originally paid for such Shares, or (b) the excess, if any, of the fair market value of the Shares on the Grant Date over the exercise price per Share. The amount of ordinary compensation income that a participant recognizes upon tender of his or her shares under the Employee Stock Purchase Plan will be subject to ordinary income and employment taxes and will be included on the participant’s year 2005 Internal Revenue Service Form W-2.

      In addition to any amount recognized by a participant under the Employee Stock Purchase Plan as ordinary compensation income, as described above, the participant may recognize capital gain (or loss) or dividend income as a result of the tender and sale of Shares in the Offer. For a general summary of these consequences relating to the sale of Shares in the Offer, please refer to the section of the Offer to Purchase captioned “The Offer — Certain U.S. Federal Income Tax Consequences — Consequences to United States Holders.”

      Unless you direct the ESPP Plan Administrator on the attached Instruction Form to tender the Shares held in your Employee Stock Purchase Plan account, no Shares will be tendered.

      If you wish to tender your Shares, complete the Information Form and return it to the ESPP Plan Administrator at one of the addresses or the fax number listed below:

      A shareholder may tender Shares subject to the condition that a specified minimum number of the shareholder’s Shares tendered pursuant to this Instruction Form must be purchased by the tendering shareholder if any Shares tendered are purchased, all as described in the Offer to Purchase, particularly in Section 6 thereof. Unless the minimum number of Shares indicated below is purchased from the tendering shareholder by the Company in the Offer, none of the Shares tendered by such shareholder will be purchased. It is the responsibility of the tendering shareholder to calculate that minimum number of Shares that must be purchased from the tendering shareholder if any are purchased, and the Company urges shareholders to consult their own tax advisor before completing this section. Unless this box has been checked and a minimum specified, the tender will be deemed unconditional.

GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION

NUMBER ON SUBSTITUTE FORM W-9

Guidelines for Determining the Proper Identification Number to Give the Payor.

      Social Security numbers have nine digits separated by two hyphens: i.e., 000-00-0000. Employer identification numbers have nine digits separated by only one hyphen: i.e., 00-0000000. The table below will help determine the number to give the payor.

For this type of account:
		Give the name and SOCIAL
		SECURITY number of:
1.	An individual’s account	The individual
2.	Two or more individuals (joint account)	The actual owner of the account or, if combined funds, the first individual on the account(1)
3.	Custodian account of a minor (Uniform Gift to Minors Act)	The minor(2)
4.	a. The usual revocable savings trust (grantor is also trustee)	The grantor-trustee(1)
	b. So-called trust account that is not a legal or valid trust under state law	The actual owner(1)
5.	Sole proprietorship or single-owner LLC	The owner(3)

		Give the name
For this type of account:		and EMPLOYER
		IDENTIFICATION number of:
6.	Sole proprietorship or single-owner LLC	The owner(3)
7.	A valid trust, estate, or pension trust	The legal entity(4)

(1)	List first and circle the name of the person whose number you furnish. If only one person on a joint account has a Social Security number, that person’s number must be furnished.
(2)	Circle the minor’s name and furnish the minor’s social security number.
(3)	Owner must show his individual name, but may also enter his business or “DBA” name. Owner may use either owner’s social security number or owner’s employer identification number.
(4)	List first and circle the name of the legal trust, estate or pension trust. (Do not furnish the taxpayer identification number of the personal representative or trustee unless the legal entity itself is not designated in the account title.)

Note:  If no name is circled when more than one name is listed, the number will be considered to be that of the first name listed.

      Resident alien individuals: If you are a resident alien individual and you do not have, and are not eligible to get, a Social Security number, your taxpayer identification number is your individual taxpayer identification number (“ITIN”) as issued by the Internal Revenue Service (“IRS”). Enter it on the portion of the Substitute Form W-9 where the Social Security number would otherwise be entered. If you do not have an ITIN, see “Obtaining a Number” below.

Name:

      If you are an individual, generally provide the name shown on your social security card. However, if you have changed your last name, for instance, due to marriage, without informing the Social Security Administration of the name change, please enter your first name and both the last name shown on your social security card and your new last name.

Obtaining a Number:

If you do not have a taxpayer identification number, obtain IRS Form SS-5, Application for a Social Security Card (for individuals), or IRS Form SS-4, Application for Employer Identification Number (for businesses and all other entities), at the local office of the Social Security Administration or the IRS and apply for a number. Resident alien individuals who are not eligible to get a Social Security number and need an ITIN should obtain IRS Form W-7, Application for IRS Individual Taxpayer Identification Number, from the IRS.

Payees and Payments Exempt from Backup Withholding:

The following is a list of payees exempt from backup withholding and for which no information reporting is required. For interest and dividends, all listed payees are exempt except the payee in item (9). For broker transactions, payees listed in items (1) through (13) and a person registered under the Investment Advisers Act of 1940 who regularly acts as a broker are exempt. For barter exchange transactions and patronage dividends, payees listed in (1) through (5) are exempt. Payments subject to reporting under sections 6041 and 6041A are generally exempt from backup withholding only if made to payees described in items (1) through (7). Unless otherwise indicated, all “section” references are to sections of the Internal Revenue Code of 1986, as amended (the “Code”).

(1)	An organization exempt from tax under section 501(a), or an IRA, or a custodial account under section 403(b)(7) if the account satisfies the requirements of section 401(f)(2).

  Payments of dividends and patronage dividends not generally subject to backup withholding include the following:

•  Payments to nonresident aliens subject to withholding under section 1441.

•  Payments to partnerships not engaged in a trade or business in the U.S. and which have at least one nonresident partner.

•  Payments of patronage dividends where the amount received is not paid in money.

•  Payments made by certain foreign organizations.

•  Section 404(k) distributions made by an ESOP.

  Payments of interest not generally subject to backup withholding include the following:

•  Payments of interest on obligations issued by individuals. Note: You may be subject to backup withholding if this interest is $600 or more and is paid in the course of your trade or business and you have not provided your correct taxpayer identification number to the payor.

•  Payments of tax-exempt interest (including exempt-interest dividends under section 852).

•  Payments described in section 6049(b)(5) to non-resident aliens.

•  Payments on tax-free covenant bonds under section 1451.

•  Payments made by certain foreign organizations.

•  Payments of mortgage or student loan interest to you.

Exempt payees described above should file Substitute Form W-9 to avoid possible erroneous backup withholding. File this form with the Payor; furnish your taxpayer identification number; indicate that you are exempt on the face of the form, sign and date the form and return it to the Payor. If you are a non-resident alien or a foreign entity not subject to backup withholding, file with Payor the appropriate completed IRS Form W-8 (or successor form).

  Certain payments other than interest, dividends and patronage dividends, that are not subject to information reporting are also not subject to backup withholding. For details, see Sections 6041, 6041A, 6042, 6044, 6045, 6049, 6050A and 6050N of the Code and the Treasury regulations promulgated thereunder.

  Privacy Act Notice — Section 6109 requires most recipients of dividend, interest, or other payments to give their correct taxpayer identification numbers to payors who must report the payments to the IRS. The IRS uses the numbers for identification purposes and to verify the accuracy of tax returns. The IRS also may provide this information to the Department of Justice for civil and criminal litigation and to cities, states, and the District of Columbia to carry out their tax laws. The IRS may also disclose this information to other countries under a tax treaty, or to Federal and state agencies to enforce Federal nontax criminal laws and to combat terrorism. Payors must be given the numbers whether or not recipients are required to file tax returns. Payors must generally withhold tax from payments of taxable interest, dividend, and certain other payments to a payee who does not furnish a taxpayer identification number to a payor. The current rate of such withholding tax is 28%. Certain penalties may also apply.

Penalties

(1) Penalty for failure to furnish taxpayer identification number — If you fail to furnish your correct taxpayer identification number to a payor, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

(2) Civil Penalty for false information with respect to withholding — If you make a false statement with no reasonable basis which results in no imposition of backup withholding, you are subject to a penalty of $500.

(3) Criminal Penalty for falsifying information — Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

EXHIBIT (a)(1)(G)

U.S. Trust

IMMEDIATE ATTENTION REQUIRED

October 14, 2005

Re: HCA 401(k) Plan

Dear Plan Participant:

      HCA Inc. (the “Company”) has initiated an offer (the “Offer”) to purchase up to 50,000,000 shares of the Company’s common stock at a price of not greater than $50.00 nor less than $43.00 per share. The Company is making this Offer to all shareholders and wishes to extend this Offer to participants in the Company’s 401(k) Plan who invest a portion of their account in the Company’s common stock through the HCA Stock Fund.

      If a portion of your account is invested in the Company’s common stock through the HCA Stock Fund, you have the right to tender (that is, offer to sell to the Company) some or all of your HCA Stock Fund balance by tendering the corresponding equivalent shares of the Company’s common stock (the “Equivalent Shares”), in accordance with the enclosed documents. The number of Equivalent Shares you own is calculated by dividing the market value of your HCA Stock Fund balance by the New York Stock Exchange closing price of the Company’s common stock on a particular day.

      To exercise this right, you must complete the enclosed Instruction Form and return it to U. S. Trust Company, N.A., an independent fiduciary of the 401(k) Plan (“U. S. Trust”), by 5:00 P.M., NEW YORK CITY TIME, ON TUESDAY, NOVEMBER 8, 2005, unless the Offer is extended by the Company.

      If your tender is accepted, proceeds from the sale will be deposited into your 401(k) Plan account and invested in the Plan’s Interest Income Fund unless and until you reallocate the proceeds based on your personal investment strategy.

Your Tender Decision

      The decision whether to tender some or all of your Equivalent Shares is yours alone, and neither U.S. Trust nor the Company is recommending that you tender or refrain from tendering your Equivalent Shares. In making your decision, you should consider your personal investment and retirement goals and whether the total return on your 401(k) Plan investments is likely to be greater by retaining your Equivalent Shares or by tendering Equivalent Shares and reinvesting the sale proceeds (if the tender is accepted). On one hand, by selling a portion of your Equivalent Shares, you may give up some value if the Company’s stock appreciates faster than the alternative funds in which you invest the tender proceeds. On the other hand, the Offer provides you with an opportunity to diversify your holdings in the Company’s stock at a price potentially above the current trading price.

Important Documents Enclosed

      Enclosed are Offer documents and an Instruction Form that require your immediate attention. The “Letter To Participants in the HCA 401(k) Plan” summarizes the Offer, your rights under the 401(k) Plan and the procedures for completing the Instruction Form. You should also review the more detailed explanation of the transaction provided in the other tender offer materials enclosed with this letter, including the Offer to Purchase and the related Letter of Transmittal. It is important that you read the enclosed documents carefully before you make a decision whether or not to tender any of your Equivalent Shares.

Offer to Purchase for Cash

Up to 50,000,000 Shares of its Common Stock

at a Purchase Price not greater than $50.00

nor less than $43.00 per Share

THE OFFER, WITHDRAWAL RIGHTS AND PRORATION PERIOD WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON MONDAY, NOVEMBER 14, 2005, UNLESS THE OFFER IS EXTENDED

To Participants in the HCA 401(k) Plan:

      HCA Inc. (the “Company”) has announced an offer to purchase for cash up to 50,000,000 shares (or such lesser number of shares as are properly tendered and not properly withdrawn) of its common stock, $0.01 par value per share (the “Shares”), at a price not greater than $50.00 nor less than $43.00 per Share, net to the seller in cash less any applicable withholding taxes, without interest (the “Offer”). The Offer is being made upon the terms and subject to the conditions set forth in the Offer to Purchase and the related Letter of Transmittal, which are enclosed, as amended or supplemented from time to time.

      As a participant in the HCA 401(k) Plan (the “401(k) Plan”), a portion of your 401(k) Plan account may be invested in the Company’s common stock through the HCA Stock Fund. In accordance with this Offer, you may tender (in other words, offer to sell to the Company) some or all of your HCA Stock Fund balance by tendering the corresponding equivalent shares of the Company’s common stock (the “Equivalent Shares”).

      The number of Equivalent Shares you own can be determined by dividing the market value of your HCA Stock Fund balance by the New York Stock Exchange closing price of the Company’s common stock on a particular day. You may determine the number of Equivalent Shares in your 401(k) Plan account from time to time either through the Internet at www.hcabenefits.com or by calling LifeTimes Connection at (800) 566-4114. Please note that the number of Equivalent Shares credited to your 401(k) Plan account may change prior to the expiration of the Offer period as a result of additional 401(k) and matching contributions being made, as well as by any investment changes you may make.

      If you do not wish to tender any portion of your Equivalent Shares, you do not need to take any action. If you would like to tender some or all of your Equivalent Shares in response to the Offer, you must complete the Instruction Form included with this document and return it to U.S. Trust Company, N.A., the independent fiduciary of the 401(k) Plan charged with supervising the Offer process (“U.S. Trust”), at the address or fax number provided below so that U.S. Trust receives it no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005, unless the Offer is extended by the Company.

      The Offer. The Company will select the lowest purchase price (the “Purchase Price”) that is produced by the tender offer process (within the range of share prices specified above) that will allow it to purchase 50,000,000 Shares, or such lesser number of Shares as are properly tendered and not properly withdrawn pursuant to the Offer. The Company will pay the same Purchase Price for all Shares purchased in the Offer. All Shares properly tendered at prices at or below the Purchase Price and not properly withdrawn will be purchased, subject to the conditions of the Offer and the “odd lot,” proration and conditional tender provisions described in the Offer to Purchase. The Company reserves the right, in its sole discretion, to purchase more than 50,000,000 Shares pursuant to the Offer, subject to compliance with applicable law.

      Providing Tender Instructions. In order to tender any portion of your Equivalent Shares, you must return the enclosed Instruction Form to U.S. Trust at the address or fax number provided so that it is received no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005. U.S. Trust will work with the Tabulation Agent for the Offer to collect and tabulate all Instruction Forms received for 401(k) Plan participants. Based on the properly completed Instruction Forms received by the deadline, all participant instructions will be combined and submitted in one or more Letters of Transmittal, as necessary, on behalf of all 401(k) Plan participants who timely elected to tender a portion of their Equivalent Shares.

      You must use the attached Instruction Form to properly tender Equivalent Shares that are held in your 401(k) Plan account. You cannot use the Letter of Transmittal to tender Equivalent Shares under the 401(k) Plan. If you hold Shares outside of the 401(k) Plan, however, and wish to tender those Shares, you must comply with the procedures described in the Letter of Transmittal and the Offer to Purchase for your Shares outside of the 401(k) Plan, and submit an Instruction Form for Equivalent Shares you hold in your 401(k) Plan account. You should also read the Offer to Purchase and Letter of Transmittal carefully before making any decision regarding the Offer.

      Please note the following:

      1. If U.S. Trust has not received your Instruction Form at least three business days before the expiration of the Offer, U.S. Trust will not tender any Equivalent Shares held in your 401(k) Plan account. The Offer, withdrawal rights and proration period will expire at 5:00 p.m., New York City time, on Monday, November 14, 2005, unless the expiration date of the Offer is extended. Consequently, to allow time for processing, your Instruction Form must be received by U.S. Trust no later than 5:00 p.m., New York City time, on Tuesday, November 8, 2005, unless the Offer is extended by the Company.

      2. If you want to tender Equivalent Shares from your 401(k) Plan account, you must specify on the Instruction Form what percentage of your HCA Stock Fund balance and the corresponding Equivalent Shares you wish to tender and at what price you want to tender such Equivalent Shares.

      3. Equivalent Shares held in your 401(k) Plan account may be tendered at prices not greater than $50.00 nor less than $43.00 per Share. However, the 401(k) Plan is prohibited by law from selling Shares to the Company for a price that is less than the prevailing market price of the Company’s common stock. Accordingly, if you elect to tender Equivalent Shares at a price that is lower than the closing price of the Company’s common stock on the date the Offer expires, the tender price you elect will be deemed to have been increased to the closest tender price that is not less than the closing price of the Company’s common stock on the New York Stock Exchange on the date the Offer expires. This could result in the selected percentage of your Equivalent Shares not being purchased in the Offer. If the closing price of the Company’s common stock on the date the Offer expires is greater than the maximum price available in the Offer, none of the Equivalent Shares will be tendered and your tender will be deemed to have been withdrawn.

      4. The Offer is for up to 50,000,000 Shares, constituting approximately 11.0% of the outstanding Shares of the Company as of September 30, 2005. The Offer is not conditioned on any minimum number of Shares being tendered. However, the Offer is subject to other conditions described in the Offer to Purchase, including amending the Company’s existing credit facility or refinancing it pursuant to the terms and conditions contained in the Refinancing Commitment Letter (as defined in the Offer to Purchase) and obtaining the necessary financing for the Offer pursuant to the terms and conditions contained in the Term Facility Commitment Letter (as defined in the Offer to Purchase).

      5. The Company’s Board of Directors has approved the making of the Offer. However, neither the Company nor the Company’s Board of Directors nor U.S. Trust is making any recommendation whether you should tender or refrain from tendering your Equivalent Shares or at what purchase price you should choose to tender your Equivalent Shares. You must make your own decision as to whether to tender your Equivalent Shares and, if so, how many Equivalent Shares to tender and the price or prices at which you will tender them. The Company’s directors and executive officers have informed the Company that they do not intend to tender Shares pursuant to the Offer.

2

      6. Tendering participants will not be obligated to pay any brokerage fees or commissions or solicitation fees to tender their Equivalent Shares. Tendering participants will not be obligated to pay any stock transfer taxes on the transfer of Equivalent Shares pursuant to the Offer.

      7. As more fully described in the Offer to Purchase, tenders will be deemed irrevocable unless timely withdrawn. If you instruct U.S. Trust to tender the Equivalent Shares held in your 401(k) Plan account, and you subsequently decide to change your instructions or withdraw your tender of Equivalent Shares, you may do so by submitting a new Instruction Form. However, the new Instruction Form will be effective only if it is received by U.S. Trust, on or before 5:00 p.m., New York City time, on Tuesday, November 8, 2005, three business days before the expiration of the Offer, unless the offer is extended. The Offer is scheduled to expire at 5:00 p.m., New York City time, on Monday, November 14, 2005. Upon receipt of a timely submitted, new Instruction Form, your previous Instruction Form to tender Equivalent Shares will be deemed canceled. If your new Instruction Form directed U.S. Trust to withdraw from tender the Equivalent Shares held in your 401(k) Plan account, you may later re-tender those Equivalent Shares by submitting a new Instruction Form so long as it is received by U.S. Trust on or before three business days before the expiration of the Offer.

      8. Contributions to the HCA Stock Fund may continue throughout the Offer. FOR ADMINISTRATIVE PURPOSES, PARTICIPANTS WHO DIRECT THE TENDER OF ALL OR A PORTION OF THEIR EQUIVALENT SHARES WILL NOT BE ABLE TO DIRECT THE DISPOSITION OF THE TENDERED PORTION OF THEIR EQUIVALENT SHARES, OR REQUEST A LOAN OR DISTRIBUTION THAT RELATES TO THE TENDERED PORTION OF THEIR EQUIVALENT SHARES, AT ANY TIME FROM THE BEGINNING OF THE BUSINESS DAY PRIOR TO THE EXPIRATION DATE OF THE OFFER (i.e., NOVEMBER 10, 2005, UNLESS THE OFFER IS EXTENDED) UNTIL 5:00 P.M., NEW YORK CITY TIME, ON THE BUSINESS DAY FOLLOWING THE DATE THE COMPANY GIVES ORAL OR WRITTEN NOTICE TO THE DEPOSITARY OF ITS ACCEPTANCE OF SHARES FOR PAYMENT IN THE OFFER.

PARTICIPANTS WHOSE TENDER INSTRUCTION IS ACCEPTED BY THE COMPANY WILL CONTINUE TO BE PROHIBITED FROM DIRECTING THE DISPOSITION OF THE TENDERED PORTION OF THEIR EQUIVALENT SHARES, AND WILL BE PROHIBITED FROM REQUESTING A LOAN OR DISTRIBUTION THAT RELATES TO THE TENDERED PORTION OF THEIR EQUIVALENT SHARES, UNTIL THE 401(k) PLAN RECEIVES THE PROCEEDS FROM THE TENDER OFFER AND COMPLETES THE TRANSFER OF THE TENDERED PORTION OF THE EQUIVALENT SHARES INTO THE HCA INTEREST INCOME FUND.

YOU SHOULD EVALUATE THE APPROPRIATENESS OF YOUR CURRENT INVESTMENT DECISIONS IN LIGHT OF THE FOREGOING LIMITATIONS.

PARTICIPANTS WHO SUBMIT A TENDER INSTRUCTION FOR ONLY A PORTION OF THEIR EQUIVALENT SHARES WILL ONLY BE SUBJECT TO THE LIMITATIONS DESCRIBED ABOVE AS THEY RELATE TO THE TENDERED PORTION OF THEIR EQUIVALENT SHARES.

PARTICIPANTS WHO DO NOT SUBMIT A TENDER INSTRUCTION FOR ANY PORTION OF THEIR EQUIVALENT SHARES WILL NOT BE SUBJECT TO THE LIMITATIONS DESCRIBED ABOVE.

      9. If you tender Equivalent Shares and such shares are accepted, the tender proceeds will be deposited into your 401(k) Plan account and invested in the 401(k) Plan’s Interest Income Fund unless and until you allocate the proceeds among the various investment funds under the 401(k) Plan according to your personal investment strategy.

      10. While you will not recognize any immediate tax gain or loss as a result of the Offer or the sale of Equivalent Shares in the Offer, the tax treatment of future withdrawals by you or distributions to you from the 401(k) Plan may be adversely affected by a tender and sale of Equivalent Shares within the 401(k) Plan. Specifically, under current federal income tax rules, if you receive a lump sum distribution from a 401(k) Plan including shares of the Company’s stock that have increased in value from the price at which they were acquired by the 401(k) Plan, under certain circumstances you may have the option of not paying tax on this increase in

3

value, which is called “net unrealized appreciation,” until you sell those shares. When the shares of the Company’s stock are sold, any gain up to the amount of the untaxed net unrealized appreciation is taxed as long-term capital gain rather than at ordinary income tax rates, which will apply to all other distributions from the 401(k) Plan and which may be a higher rate for certain participants. If Equivalent Shares credited to your individual 401(k) Plan account are purchased by the Company in the Offer, you will no longer be able to take advantage of this tax benefit with respect to the shares of the Company’s stock purchased by the Company in the Offer (unless you elect to reinvest in the HCA Stock Fund within 90 days after the purchase). You can find additional tax information relating to the Offer in the Offer to Purchase. You are further advised to consult with your tax advisor concerning your decision to participate in the Offer.

and Equivalent Shares

STEP 1

Indicate a percentage (from 1% to 100%):

      I wish to tender _______________% of my HCA Stock Fund balance and the corresponding Equivalent Shares held in my HCA 401(k) Plan account.

STEP 2

Check one Option below. If you choose Option B, you must also check a box to indicate your tender price.

o Option A*

o Option B*

Check this Option if you want to maximize the chance of having the Company accept for purchase all of the percentage of your Equivalent Shares shown in Step 1(subject to the possibility of proration). Accordingly, by checking this box, you are tendering the percentage of your Equivalent Shares shown in Step 1 and are willing to accept the purchase price determined by the Company in accordance with the terms of the Offer. You understand that this action could result in receiving a price per Equivalent Share as low as $43.00.

By checking one of the boxes below, you are tendering the percentage of your Equivalent Shares shown in Step 1 at the price checked. You are also indicating that you understand this action could result in none of your Equivalent Shares being purchased if the purchase price determined by the Company is less than the price checked below. You may only check one of the boxes below. Price (in Dollars) Per Equivalent Share Tender price is not to be less than $43.00 or exceed $50.00. o  $43.00  o $44.25   o $45.50  o $46.75   o $48.00  o $49.25 o  $43.25  o $44.50   o $45.75  o $47.00   o $48.25  o $49.50 o  $43.50  o $44.75   o $46.00  o $47.25   o $48.50  o $49.75 o  $43.75  o $45.00   o $46.25  o $47.50   o $48.75  o $50.00 o  $44.00  o $45.25   o $46.50  o $47.75   o $49.00

* Please note that the 401(k) Plan is prohibited by law from selling Shares to the Company for a price that is less than the prevailing market price of the Company’s common stock. Accordingly, if you elect to tender Equivalent Shares at a price that is lower than the closing price of the Company’s common stock on the date the Offer expires, the tender price you elect will be deemed to have been increased to the closest tender price that is not less than the closing price of the Company’s common stock on the New York Stock Exchange on the date the Offer expires. This could result in the selected percentage of your Equivalent Shares not being purchased in the Offer. If the closing price of the Company’s common stock on the date the Offer expires is greater than the maximum price available in the Offer, none of the Equivalent Shares will be tendered and your tender will be deemed to have been withdrawn.

Notice of Offer to Purchase for Cash

Up to 50,000,000 Shares of its Common Stock

at a Purchase Price not greater than $50.00

nor less than $43.00 per Share

THE OFFER, WITHDRAWAL RIGHTS AND PRORATION PERIOD WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON MONDAY, NOVEMBER 14, 2005, UNLESS THE OFFER IS EXTENDED.

       HCA Inc., a Delaware corporation (the “Company”), is offering to purchase for cash up to 50,000,000 shares (or such lesser number of shares as are properly tendered and not properly withdrawn) of its common stock, par value $0.01 per share (the “Shares”), upon the terms and subject to the conditions set forth in the Offer to Purchase dated October 14, 2005 (the “Offer to Purchase”), and in the related Letter of Transmittal (which together, as they may be amended and supplemented from time to time, constitute the “Offer”).

      The Company is inviting its shareholders to tender their Shares at prices specified by the tendering shareholders that are not greater than $50.00 nor less than $43.00 per Share, net to the seller in cash less any applicable withholding taxes, without interest, upon the terms and subject to the conditions of the Offer. The Offer is not conditioned on any minimum number of Shares being tendered. However, the Offer is subject to other conditions described in Section 7 of the Offer to Purchase, including amending our existing credit facility or refinancing it pursuant to the terms and conditions contained in the Refinancing Commitment Letter (as defined in the Offer to Purchase) and obtaining the necessary financing for the Offer pursuant to the terms and conditions contained in the Term Facility Commitment Letter (as defined in the Offer to Purchase).

      The Company’s Board of Directors has approved the Offer. However, neither the Company nor its Board of Directors, the Lead Dealer Manager, the Dealer Manager, the Information Agent or the Depositary (each as defined below) are making any recommendation to the Company’s shareholders as to whether to tender or refrain from tendering their Shares or as to the price or prices at which shareholders may choose to tender their Shares. Shareholders must make their own decision as to whether to tender their Shares and, if so, how many Shares to tender and the price or prices at which such Shares should be tendered. The Company’s directors and executive officers have advised HCA that they do not intend to tender Shares pursuant to the Offer.

      In accordance with Instruction 5 of the Letter of Transmittal, shareholders desiring to tender Shares must either (1) specify that they are willing to sell their Shares to the Company at the price determined in the Offer, or (2) specify the price, not greater than $50.00 nor less than $43.00 per Share, at which they are willing to sell their Shares to the Company in the Offer. Shareholders must follow the procedures set forth in Section 3 of the Offer to Purchase and in the Letter of Transmittal (or, in the case of shareholders tendering Shares held in an account under

the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan, must follow the procedures set forth in the “Letter to Participants in the Amended and Restated HCA Employee Stock Purchase Plan” and the “Letter to Participants in the HCA 401(k) Plan,” respectively).

      The Company will, upon the terms and subject to the conditions of the Offer, determine the price per Share, not greater than $50.00 nor less than $43.00 per Share, that it will pay for Shares properly tendered under the Offer, taking into account the number of Shares so tendered and the prices specified by tendering shareholders. The Company will select the lowest purchase price (the “Purchase Price”) that will allow it to purchase 50,000,000 Shares, or such lesser number of Shares as are properly tendered and not properly withdrawn pursuant to the Offer. All Shares properly tendered and not properly withdrawn prior to 5:00 p.m., New York City time, on Monday, November 14, 2005 (the “Expiration Date,” unless the Company, in its sole discretion, extends the period of time during which the Offer will remain open, in which event the term “Expiration Date” shall refer to the latest time and date at which the Offer, as so extended by the Company, shall expire), at prices at or below the Purchase Price will be purchased at the Purchase Price, upon the terms and subject to the conditions of the Offer, including the “odd lot,” proration and conditional tender provisions.

      Under no circumstances will interest be paid on the Purchase Price for the Shares, regardless of any delay in making payment for the Shares. All Shares acquired in the Offer will be acquired at the same Purchase Price regardless of whether the shareholder selected a lower price. The Company reserves the right, in its sole discretion, to purchase more than 50,000,000 Shares under the Offer subject to certain limitations and legal requirements. For purposes of the Offer, the Company will be deemed to have accepted for payment (and therefore purchased) Shares properly tendered and not withdrawn, subject to the “odd lot,” proration and conditional tender provisions of the Offer, only when, as and if the Company gives oral or written notice to National City Bank, the Depositary of the Offer, of its acceptance for payment of such Shares under the Offer.

      Payment for Shares tendered and accepted for payment under the Offer will be made only after timely receipt by the Depositary of certificates for such Shares or a timely confirmation of a book-entry transfer of such Shares into the Depositary’s account at the “Book-Entry Transfer Facility” (as defined in the Offer to Purchase), a properly completed and duly executed Letter of Transmittal (or a manually signed facsimile of the Letter of Transmittal), an Agent’s Message (as defined in the Offer to Purchase) in the case of a book-entry transfer, or the specific acknowledgement in the case of a tender through the Automated Tender Offer Program of the Book-Entry Transfer Facility (as defined in the Offer to Purchase) and any other documents required by the Letter of Transmittal.

      Upon the terms and subject to the conditions of the Offer, if at the Expiration Date more than 50,000,000 Shares (or such greater number of Shares as the Company may elect to purchase) are properly tendered at or below the Purchase Price and not withdrawn, the Company will purchase 50,000,000 Shares, such Shares to be purchased: first, from all of the Company’s holders of “odd lots” of less than 100 Shares (not including any Shares held in the Amended and Restated HCA Employee Stock Purchase Plan or the HCA 401(k) Plan, which will not have priority) who properly tender all of their Shares at or below the Purchase Price selected by the Company; second, after purchasing all Shares from the “odd lot” holders, from all other shareholders (including participants in the Amended and Restated HCA Employee Stock Purchase Plan and the HCA 401(k) Plan) who properly tender Shares at or below the Purchase Price selected by the Company, on a pro rata basis, subject to the conditional tender provisions described in Section 6 of the Offer to Purchase; and third, if necessary to permit the Company to purchase 50,000,000 Shares, to the extent feasible, by random lot out of Shares conditionally tendered (for which the condition was not initially satisfied) at or below the purchase price selected by the Company. To be eligible for purchase by random lot, shareholders whose Shares are conditionally tendered must have tendered all of their Shares. See Sections 1 and 6 of the Offer to Purchase.

      The Company expressly reserves the right, in its sole discretion, at any time and from time to time, to extend the period of time during which the Offer is open and thereby delay acceptance for payment of, and payment for, any Shares by giving oral or written notice of such extension to the Depositary and making a public announcement thereof no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date. During any such extension, all Shares previously tendered and not properly withdrawn will remain subject to the Offer and to the right of a tendering shareholder to withdraw such shareholder’s Shares.

2

      Tenders of Shares under the Offer are irrevocable, except that tendered Shares may be withdrawn at any time prior to the Expiration Date and, unless previously accepted for payment by the Company under the Offer prior to such withdrawal, may also be withdrawn at any time after 5:00 p.m., New York City time, on December 13, 2005. For withdrawal to be effective, a written or facsimile transmission notice of withdrawal must be timely received by the Depositary at its address set forth on the back cover of the Offer to Purchase. Any such notice of withdrawal must specify the name of the tendering shareholder, the number of Shares to be withdrawn and the name of the registered holder of such Shares. If the certificates for Shares to be withdrawn have been delivered or otherwise identified to the Depositary, then, before the release of such certificates, the serial numbers shown on such certificates must be submitted to the Depositary and the signature(s) on the notice of withdrawal must be guaranteed by an “Eligible Institution” (as defined in the Offer to Purchase), unless such Shares have been tendered for the account of an Eligible Institution. If Shares have been tendered pursuant to the procedure for book-entry transfer set forth in the Offer to Purchase, any notice of withdrawal also must specify the name and the number of the account at the Book-Entry Transfer Facility to be credited with the withdrawn Shares and must otherwise comply with such Book-Entry Transfer Facility’s procedures. All questions as to the form and validity of any notice of withdrawal, including the time of receipt, will be determined by the Company, in its sole discretion, whose determination will be final and binding. None of the Company, National City Bank, as the Depositary, Georgeson Shareholder Communications, Inc., as the Information Agent, Merrill Lynch & Co., as the Lead Dealer Manager, and JPMorgan, as the Dealer Manager, or any other person will be under any duty to give notification of any defects or irregularities in any tender or notice of withdrawal or incur any liability for failure to give any such notification.

      In certain circumstances, some tendering shareholders whose Shares are purchased in the Offer may be treated for U.S. federal tax purposes as having received an amount taxable as a distribution or dividend rather than as recognizing a capital gain or loss. Shareholders are strongly encouraged to read the Offer to Purchase for additional information regarding the U.S. federal tax consequences of participating in the Offer.

      The information required to be disclosed by Rule 13e-4(d)(1) under the Securities Exchange Act of 1934, as amended, is contained in the Offer to Purchase and is incorporated herein by reference.

      The Offer to Purchase and the related Letter of Transmittal are being mailed to record holders of Shares whose names appear on the Company’s shareholder list and will be furnished to brokers, dealers, commercial banks, trust companies and similar persons whose names, or the names of whose nominees, appear on the shareholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing for subsequent transmittal to beneficial owners of Shares.

      The Offer to Purchase and the related Letter of Transmittal contain important information. Shareholders should read them carefully before making any decision regarding the Offer.

      Any questions or requests for assistance may be directed to the Information Agent or the Lead Dealer Manager at the respective telephone numbers and addresses set forth below. Additional copies of the Offer to Purchase, the Letter of Transmittal and the Notice of Guaranteed Delivery may be obtained from the Information Agent at the address and telephone number set forth below and will be promptly furnished by the Company at its expense. Shareholders may also contact their broker, dealer, commercial bank, trust company or nominee for assistance concerning the Offer.

EXHIBIT (a)(5)(D)

October 14, 2005

To Our Shareholders:

      HCA Inc. is offering to purchase up to 50,000,000 shares of our common stock from you, in each case at a price within the range of $43.00 to $50.00 per share, net to the seller in cash less any applicable withholding taxes, without interest.

      Holders of common stock are invited to tender their shares to us through a procedure commonly referred to as a modified “Dutch” auction tender offer. This procedure allows you to select the price within the range of $43.00 and $50.00 per share at which you are willing to sell your shares to us. Our common stock was trading at $46.69 per share as of the close of the market on October 12, 2005, the day before we announced the offer.

      Based on the number of shares tendered and the prices specified by our shareholders, we will determine the lowest single per share price that will allow us to purchase up to 50,000,000 shares (or such lesser amount of shares as are properly tendered and not properly withdrawn). We will pay the selected price for all shares of common stock tendered at or below that price. All shares which you tender but which we do not purchase will be returned to you promptly after the expiration of the tender offer.

      Any shareholder whose shares are properly tendered directly to National City Bank, the Depositary for the offer, and purchased in the offer will receive the net purchase price in cash, without interest, promptly after the expiration of the offer.

      Our Board of Directors, with the assistance of management and outside advisors, considered and approved the offer because it concluded that increasing the Company’s indebtedness to fund the tender offer is a prudent use of the Company’s financial resources and an effective means of providing value to the Company’s shareholders. However, neither we nor the Board of Directors, the Lead Dealer Manager (as defined below), the Dealer Manager, the Information Agent (as defined below) or the Depositary are making any recommendation to you as to whether to tender or refrain from tendering shares or as to the purchase price or prices at which you may choose to tender your shares. Our directors and executive officers have advised us that they do not intend to tender shares pursuant to the offer. You must make your own decision regarding whether to accept this offer and, if so, how many shares to tender and at what price.

      The offer is explained in detail in the enclosed Offer to Purchase and Letter of Transmittal. This letter is only a summary, and I encourage you to read these documents carefully before making any decision with respect to the offer. The instructions on how to tender shares are explained in detail in the accompanying materials.

      The offer will expire at 5:00 p.m., New York City time, on Monday, November 14, 2005, unless we extend the offer. Questions and requests for assistance may be directed to Georgeson Shareholder Communications, Inc., our Information Agent, and Merrill, Lynch & Co., our Lead Dealer Manager, in each case at the telephone numbers and addresses set forth on the back cover of the Offer to Purchase. You may request additional copies of the Offer to Purchase and other Offer documents from the Information Agent at the telephone number and address on the back cover of the Offer to Purchase.

Very truly yours,
