Represents the number of shares of common stock, no par value, of the registrant estimated to be issuable in connection with the proposed merger (the "merger") of Empire Merger Sub, Corp., a New York corporation and a wholly owned subsidiary of the registrant, with and into Welch Allyn Holdings Inc., a New York corporation ("Welch Allyn"). Pursuant to Rule 416 under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the "Securities Act"), this registration statement also covers an indeterminate number of additional shares of the registrant's common stock as may be issuable as a result of reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, stock dividends or similar transactions or events.

(2)

Estimated solely for the purpose of calculating the registration fee in accordance with Rule 457(f) under the Securities Act. Welch Allyn is a private company and no market exists for its equity securities. Pursuant to Rule 457(f)(2) under the Securities Act, the proposed maximum aggregate offering price of the registrant's common stock was calculated based on $561,593,000, the aggregate book value of (i) shares of common stock—Class A, no par value per share, of Welch Allyn and (ii) shares of common stock—Class B, $0.01 par value per share, of Welch Allyn, in each case, to be cancelled and exchanged for shares of the registrant's common stock in the merger, as of May 30, 2015, the latest practicable date prior to the date of filing of this registration statement. As required by Rule 457(f)(3) under the Securities Act, the estimated aggregate amount of cash to be paid by the registrant in the merger, or approximately $1,625,000,000, has been deducted from the maximum aggregate offering price. As this results in a negative number, the maximum aggregate offering price has been estimated as $0.

Effects of the Merger; Merger Consideration
(see pages 51 and 82)

        At the effective time of the merger, each outstanding share of Welch Allyn common stock (other than any shares of Welch Allyn common stock as to which the holders of such shares have properly complied with the provisions of Sections 623 and 910 of the NYBCL as to dissenters' rights, which shares are referred to as dissenting shares in this proxy statement/prospectus, and any shares of Welch Allyn common stock owned by Hill-Rom, Merger Sub or any subsidiary of Hill-Rom) will be cancelled and automatically converted into the right to receive the merger consideration consisting of a combination of cash and shares of Hill-Rom common stock.

        Upon the terms and subject to the conditions set forth in the merger agreement and subject to certain adjustments as described more fully in this proxy statement/prospectus, Welch Allyn shareholders will receive in the aggregate approximately:

•

$1,625,000,000 in cash (which amount is subject to adjustments for cash and cash equivalents, indebtedness (as defined in the merger agreement), certain other adjustments (as defined in the merger agreement), including the amount of certain fees, costs and expenses of Welch Allyn and the shareholder representative, net working capital, certain change in control payments (as defined in the merger agreement), including LTIP cash incentive payments (as defined in the merger agreement), payments to the holders of Welch Allyn PHASARs and PSU Awards (other than any portion of such payments deposited in the escrow account)), which amount is referred to as the cash consideration in this proxy statement/prospectus; and



•

8,133,722 shares of Hill-Rom common stock, which are referred to as the stock consideration in this proxy statement/prospectus.

        $75,000,000 of the cash consideration otherwise deliverable to holders of outstanding shares of Welch Allyn common stock, PHASARs and PSU Awards will be withheld pro rata from such holders and deposited in an escrow account to secure any post-closing adjustment to the closing cash consideration and certain indemnification obligations of such holders pursuant to the merger agreement. These funds will be released by the escrow agent in accordance with the terms set forth in the escrow agreement. For more information regarding the adjustments and the amounts withheld under the escrow agreement, see the sections entitled "The Merger Agreement—Merger Consideration Adjustments" and "The Merger Agreement—Escrow" beginning on pages 85 and 84, respectively, of this proxy statement/prospectus and the merger agreement attached to this proxy statement/prospectus as Annex A. The aggregate amount of the cash consideration will not be known until shortly before the effective time of the merger.

        The merger consideration will be allocated among Welch Allyn shareholders. The precise amount of the merger consideration to be paid to each Welch Allyn shareholder will vary, depending on the amount of the cash consideration and the number of shares of Welch Allyn common stock outstanding immediately prior to the effective time of the merger.

        Hill-Rom will not issue fractional shares of Hill-Rom common stock in the merger. As a result, Welch Allyn shareholders will receive cash for any fractional share of Hill-Rom common stock that they would otherwise be entitled to receive in the merger.

        For a full description of the merger consideration, see the section titled "The Merger Agreement—Effects of the Merger; Merger Consideration" beginning on page 82 of this proxy statement/prospectus.

Treatment of Welch Allyn PHASARs, PSU Awards and LTIP Cash Incentive Awards
(see page 52)

        At the effective time of the merger:

•

each outstanding PHASAR, whether vested or unvested, will be cancelled, with the holder of such PHASAR becoming entitled to receive an amount in cash equal to the product of (a) the number of phantom shares of Welch Allyn common stock ("Phantom Shares") subject to such PHASAR as of immediately prior to the effective time of the merger and (b) the excess, if any, of the Phantom Merger Consideration (as defined below) (divided by 20 in the case of any PHASAR granted prior to January 1, 2012) over the grant price of such PHASAR, less any required withholding taxes;



•

each outstanding PSU Award will be cancelled, with the holder of such PSU Award becoming entitled to receive an amount in cash equal to the product of (a) the number of Phantom Shares subject to such PSU Award as of immediately prior to the effective time of the merger and (b) the Phantom Merger Consideration (divided by 20 in the case of any PSU Award granted prior to January 1, 2012), less any required withholding taxes; and



•

each outstanding LTIP Cash Incentive Award will be cancelled, with the holder of such LTIP Cash Incentive Award becoming entitled to receive an amount in cash equal to the total cash amount subject to such LTIP Cash Incentive Award, assuming satisfaction of performance goals at target levels, less any required withholding taxes.

        The "Phantom Merger Consideration" is an amount in cash equal to the quotient of (a) the sum of (i) the cash consideration, subject to the adjustments to cash consideration described above, excluding the adjustment for payments of PHASAR and PSU awards, (ii) the cash value of the stock consideration at the effective time of the merger (determined pursuant to the merger agreement) and (iii) the sum of the grant prices of each outstanding PHASAR divided by (b) the sum of (i) all shares of Welch Allyn common stock, (ii) all PHASARs and (iii) all PSU Awards, in each case, outstanding at the effective time of the merger and divided by 20 in the case of any PHASAR or PSU Award granted prior to January 1, 2012.

        If Welch Allyn, on or prior to the effective time of the merger, declares any dividends or other distributions directly or indirectly on shares of Welch Allyn common stock that are paid or set-aside on or following June 16, 2015, then the Phantom Merger Consideration as defined above will be increased by the aggregate per share amount of such dividends or other distributions.

        In addition, $75,000,000 of the cash consideration otherwise deliverable to holders of outstanding shares of Welch Allyn common stock, PHASARs and PSU Awards will be withheld pro rata from such holders and deposited in an escrow account to secure any post-closing adjustment to the closing cash consideration and certain indemnification obligations of such holders pursuant to the merger

agreement. These funds will be released by the escrow agent in accordance with the terms set forth in the escrow agreement. Pursuant to the terms of the LTIP Cash Incentive Awards and the merger agreement, no portion of the cash amount each individual receives in respect of his or her LTIP Cash Incentive Awards will be withheld under the escrow agreement. For more information regarding the adjustments and the amounts withheld under the escrow agreement, see the sections entitled "The Merger Agreement—Merger Consideration Adjustments" and "The Merger Agreement—Escrow" beginning on pages 85 and 84, respectively, and the merger agreement attached to this proxy statement/prospectus as Annex A.

        See the sections titled "The Merger—Treatment of Welch Allyn PHASARs, PSU Awards and LTIP Cash Incentive Awards" and "The Merger Agreement—Treatment of PHASARs, PSU Awards and LTIP Cash Incentive Awards" beginning on pages 52 and 87, respectively, of this proxy statement/prospectus for more information.

Ownership of Hill-Rom Following the Merger
(see page 53)

        Hill-Rom expects to issue 8,133,722 shares of Hill-Rom common stock in the merger in partial consideration for the outstanding shares of Welch Allyn common stock. Based on the number of shares of Hill-Rom common stock outstanding on June 16, 2015, immediately after completion of the merger, Welch Allyn shareholders that existed immediately prior to the merger are expected to own, in the aggregate, approximately 13% of the then outstanding shares of Hill-Rom common stock.

Financing for the Merger
(see page 95)

        Under the merger agreement, following the effectiveness of the registration statement on Form S-4 of which this proxy statement/prospectus forms a part, Welch Allyn has agreed to allow Hill-Rom and its financing sources a period of up to 20 consecutive business days (throughout which the registration statement on Form S-4 of which this proxy statement/prospectus forms a part must remain effective or such period shall restart when it becomes effective) to arrange its debt financing in an amount sufficient to complete the merger. Welch Allyn also has agreed to, and to cause its officers, employees and representatives to, provide Hill-Rom all cooperation reasonably requested that is necessary or reasonably required in connection with Hill-Rom's debt financing.

Risk Factors
(see page 29)

        In evaluating the merger agreement and the merger, you should carefully read this proxy statement/prospectus and especially consider the factors discussed in the section titled "Risk Factors" beginning on page 29 of this proxy statement/prospectus.

Vote Required
(see page 39)

        Completion of the merger is conditioned upon the adoption of the merger agreement by the affirmative vote at the special meeting, either in person or by proxy, of holders representing at least two-thirds of the outstanding shares of Welch Allyn Class A common stock. Following the execution of the merger agreement, Hill-Rom entered into a voting agreement with the voting trustees of the voting trust created under the voting trust agreement, pursuant to which the voting trustees (i) executed and delivered to Hill-Rom an irrevocable proxy with respect to the 96,406,486 shares of Welch Allyn Class A common stock subject to the voting trust agreement, which shares constitute in the aggregate 89.94% of the total number of shares of Welch Allyn Class A common stock outstanding as of the date

of this proxy statement/prospectus, and (ii) for purposes of the Shareholders' Agreement, consented to the transfer (as defined in the Shareholders' Agreement) of the shares of Welch Allyn Class A common stock subject to the voting trust, as described in more detail in the section titled "Material Contracts Between the Parties" beginning on page 101 of this proxy statement/prospectus. A copy of the voting agreement is attached to this proxy statement/prospectus as Annex B. The vote by Hill-Rom at the special meeting with respect to the shares of Welch Allyn Class A common stock subject to the irrevocable proxy to adopt the merger agreement will be sufficient to adopt the merger agreement and thereby approve the merger and the other transactions contemplated by the merger agreement, referred to in this proxy statement/prospectus as the merger proposal.

        The affirmative vote, either in person or by proxy, at a special meeting of the shareholders of Welch Allyn by holders representing a majority of the outstanding Welch Allyn Class A common stock as of the record date, is required to approve one or more adjournments of the special meeting, if necessary, to permit the Welch Allyn board of directors to solicit additional proxies in favor of the merger proposal, referred to in this proxy statement/prospectus as the adjournment proposal.

The Special Meeting
(see page 39)

        The special meeting of the shareholders of Welch Allyn will be held on [    ·    ], 2015, at [    ·    ] a.m., local time at The Lodge, located at 4355 State Street Road, Skaneateles Falls, NY 13152. At the special meeting:

        (1)   holders of Welch Allyn Class A common stock will be asked to consider and vote to approve the merger proposal; and

        (2)   holders of Welch Allyn Class A common stock will be asked to consider and vote to approve the adjournment proposal.

        With respect to the merger proposal, only the holders of record of shares of Welch Allyn Class A common stock at the close of business on [    ·    ], 2015, the record date, will be entitled to vote at the special meeting. Each share of Welch Allyn Class A common stock is entitled to one vote on the merger proposal at the special meeting and any adjournment(s) of the special meeting.

        With respect to the adjournment proposal, only the holders of record of shares of Welch Allyn Class A common stock as of the record date will be entitled to vote at the special meeting. Each share of Welch Allyn Class A common stock is entitled to one vote on the adjournment proposal at the special meeting and any adjournment(s) of the special meeting. As of the record date, there were [    ·    ] shares of Welch Allyn common stock outstanding, consisting of [    ·    ] shares of Welch Allyn Class A common stock outstanding and [    ·    ] shares of Welch Allyn Class B common stock outstanding.

        As of July 9, 2015, the directors and executive officers of Welch Allyn collectively beneficially owned 25,424,342 shares of Welch Allyn common stock (including shares of Welch Allyn Class A common stock and Welch Allyn Class B common stock), which represent, in the aggregate, approximately 23.6% of the outstanding shares of Welch Allyn common stock on that date.

        Completion of the merger is conditioned upon the adoption of the merger agreement by the affirmative vote at the special meeting, either in person or by proxy, of holders representing at least two-thirds of the outstanding shares of Welch Allyn Class A common stock. Following the execution of the merger agreement, Hill-Rom entered into a voting agreement with the voting trustees of the voting trust created under the voting trust agreement, pursuant to which the voting trustees (i) executed and delivered to Hill-Rom an irrevocable proxy with respect to the 96,406,486 shares of Welch Allyn Class A common stock subject to the voting trust agreement, which shares constitute in the aggregate 89.94% of the total number of shares of Welch Allyn Class A common stock outstanding as of the date

of this proxy statement/prospectus, and (ii) for purposes of the Shareholders' Agreement, consented to the transfer (as defined in the Shareholders' Agreement) of the shares of Welch Allyn Class A common stock subject to the voting trust, as described in more detail in the section titled "Material Contracts Between the Parties" beginning on page 101 of this proxy statement/prospectus. A copy of the voting agreement is attached to this proxy statement/prospectus as Annex B. The vote by Hill-Rom at the special meeting with respect to the shares of Welch Allyn Class A common stock subject to the irrevocable proxy to adopt the merger agreement will be sufficient to adopt the merger agreement and thereby approve the merger and the other transactions contemplated by the merger agreement. Assuming the presence of a quorum, the affirmative vote at the special meeting of holders representing a majority of the outstanding Welch Allyn Class A common stock present at the special meeting, in person or by proxy, is required to approve the adjournment proposal. If you are a Welch Allyn Class A shareholder and mark "ABSTAIN" on your proxy with respect to the merger proposal or the adjournment proposal, it will have the same effect as a vote "AGAINST" the merger proposal or the adjournment proposal, as applicable. If you fail to submit a proxy or vote in person at the special meeting with respect to the merger proposal, it will have the same effect as a vote "AGAINST" the merger proposal, while shares not in attendance at the special meeting will have no effect on the outcome of any vote to adjourn the special meeting.

Interests of Directors and Executive Officers of Welch Allyn in the Merger
(see page 67)

        In considering the recommendation of the Welch Allyn board of directors that the Welch Allyn shareholders vote to approve the merger proposal at the special meeting of Welch Allyn shareholders, you should be aware that certain of Welch Allyn's directors and executive officers have financial interests in the merger that are different from, or are in addition to, the interests of the Welch Allyn shareholders generally, as more fully described below. The members of the Welch Allyn board of directors were aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement, and in evaluating the merger and in recommending to the Welch

Allyn shareholders that they approve the merger proposal at the special meeting of Welch Allyn shareholders.

        The interests of the members of Welch Allyn's board of directors generally include the right to receive, at the effective time of the merger (1) the cancellation of each outstanding PHASAR and PSU Award immediately prior to the effective time of the merger in exchange for the right to receive the Phantom Merger Consideration with respect to such PHASAR and each PSU Award (less the grant price in the case of PHASARs) and (2) accelerated cash payment of previously earned and vested amounts deferred under the Deferred Compensation Plan for the Board of Directors of Welch Allyn (amended and restated as of January 1, 2012) (the "Directors Deferred Compensation Plan").

        The interests of Welch Allyn's executive officers include the rights to:

•

at the effective time of the merger, cancellation of each outstanding PHASAR and PSU Awards immediately prior to the effective time of the merger in exchange for the right to receive the Phantom Merger Consideration (divided by 20 in the case of any PHASAR or PSU awards granted prior to January 1, 2012) with respect to such PHASAR and each PSU Award (less the grant price in the case of PHASARs);



•

at the effective time of the merger, cancellation of each outstanding LTIP Cash Award in exchange for the total cash amount subject to such LTIP Cash Incentive Award (assuming satisfaction of performance goals at target levels);



•

at the effective time of the merger, accelerated cash payment of previously earned and vested amounts deferred under the Deferred Compensation Plan for Certain Executive Employees of Welch Allyn Companies (amended and restated as of January 1, 2014) (the "Executive Deferred Compensation Plan" and together with the Directors Deferred Compensation Plan, the "Deferred Compensation Plans");

at or following the effective time of the merger, special bonus payments to certain executive officers;



•

in the event of a qualifying termination of employment following the effective time of the merger, certain severance payments and benefits; and



•

certain continuing employee benefits following the effective time of the merger pursuant to the merger agreement.

        Welch Allyn's directors and executive officers also have the right to indemnification and insurance coverage following the effective time of the merger. Please see the section below entitled "The Merger—Interests of Directors and Executive Officers of Welch Allyn in the Merger" beginning on page 67 of this proxy statement/prospectus for additional information about these interests.

Listing of Hill-Rom Common Stock
(see page 74)

        Application will be made to have the shares of Hill-Rom common stock issued in the merger approved for listing on the NYSE.

Dissenters' Rights
(see page 74)

        Welch Allyn shareholders have dissenters' rights under the NYBCL in connection with the merger. Welch Allyn shareholders who do not vote in favor of the adoption of the merger agreement and who otherwise comply with the applicable provisions of the NYBCL will be entitled to dissent from the merger and obtain payment of the "fair value," as determined pursuant to Section 623 of the NYBCL,

of their shares if the merger is completed. Any shares of Welch Allyn common stock held by a shareholder who has not voted in favor of the adoption of the merger agreement and who has exercised dissenters' rights for such shares in accordance with the NYBCL, will not be converted into a right to receive the merger consideration, unless such shareholder fails to perfect, withdraws or otherwise loses such shareholder's right to dissent under the NYBCL. If, after the consummation of the merger, such holder of Welch Allyn common stock fails to perfect, withdraws or otherwise loses his or her or its rights to dissent, each such share will be treated as if it had been converted as of the consummation of the merger into a right to receive the merger consideration as shares that made no election.

        You are encouraged to read these provisions carefully and in their entirety. Due to the complexity of the procedures for exercising dissenters' rights, Welch Allyn shareholders who are considering exercising such rights are encouraged to seek the advice of legal counsel. Failure to strictly comply with these provisions will result in the loss of dissenters' rights. See the section entitled "The Merger—Dissenters' Rights" beginning on page 74 of this proxy statement/prospectus for additional information and the text of Sections 623 and 910 of the NYBCL reproduced in their entirety as Annex C to this proxy statement/prospectus.

Expected Timing of the Merger
(see page 65)

        Hill-Rom and Welch Allyn currently expect to complete the merger prior to September 30, 2015, subject to the receipt of regulatory approvals and the satisfaction or waiver of the other conditions to the merger contained in the merger agreement. However, it is possible that factors outside the control of Hill-Rom and Welch Allyn could require Hill-Rom and Welch Allyn to complete the merger at a later date or not complete it at all.

Regulatory Matters
(see page 73)

        United States Antitrust.    Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and related rules, which are collectively referred to as the HSR Act in this proxy statement/prospectus, certain transactions, including the merger, may not be completed until notifications have been given and information furnished to the Antitrust Division of the United States Department of Justice, which is referred to as the Antitrust Division in this proxy statement/prospectus, and the United States Federal Trade Commission, which is referred to as the FTC in this proxy statement/prospectus, and all statutory waiting period requirements have been satisfied. Hill-Rom and Welch Allyn filed Notification and Report Forms with the Antitrust Division and the FTC on June 25, 2015, and early termination of the waiting period under the HSR Act with respect to the merger was granted effective as of July 8, 2015.

        At any time before or after the effective time of the merger, the Antitrust Division, the FTC or others (including states and private parties) could take action under the antitrust laws, including seeking to prevent the merger, to rescind the merger or conditionally approve the merger upon the divestiture of assets of Hill-Rom or Welch Allyn or subject to other remedies. There can be no assurance that a challenge to the merger on antitrust grounds will not be made or, if such a challenge is made, that it would not be successful.

        Germany Antitrust.    Under the German Act against Restraints of Competition (Gesetz gegen Wettbewerbsbeschränkungen) as amended, and related rules, which are collectively referred to as the ARC in this proxy statement / prospectus, certain transactions, including the merger, may not be completed until a valid notification has been submitted to the German Federal Cartel Office, which is referred to as the FCO in this proxy statement / prospectus, and all statutory waiting period

requirements have been satisfied (or the FCO has confirmed its approval of the merger prior to the expiry of any statutory waiting period). A notification regarding the merger was filed with the FCO on June 29, 2015.

        As part of its review of the merger, the FCO could decide to prohibit the merger or to conditionally approve the merger upon the divestiture of assets of Hill-Rom or Welch Allyn, or subject the parties to other remedies. There can be no assurance that the FCO will not prohibit the merger or to conditionally approve the merger upon the divestiture of assets of Hill-Rom or Welch Allyn, or subject the parties to other remedies.

        In addition, at any time during the ARC's statutory waiting period, third parties may apply to the FCO to join the proceedings as "intervening parties" should the FCO decide that the interests of such third parties are materially affected by the merger. Intervening parties are entitled to appeal decisions of the FCO. There can be no assurance that an appeal of the FCO's decision about the merger will not be made or, if such an appeal is made, that it would not be successful.

        The foregoing is a summary of the material regulatory requirements for the merger, satisfaction or waiver of certain of which requirements is a condition to the completion of the merger. There can be no guarantee as to if and when any of the consents or approvals required for the merger will be obtained or as to the conditions that such consents and approvals may contain. For further information, see the section titled "Risk Factors" beginning on page 29 of this proxy statement/prospectus.

Opinion of the Financial Advisor to Welch Allyn
(see page 57)

        In connection with the merger, Barclays Capital Inc. ("Barclays") delivered to the Welch Allyn board of directors its written opinion dated June 16, 2015, to the effect that, as of that date and based on and subject to the various assumptions, matters considered and limitations described in its opinion, from a financial point of view, the merger consideration offered to the Welch Allyn shareholders was fair to the Welch Allyn shareholders. The full text of the written opinion of Barclays, which sets forth the assumptions made, matters considered and limits on the review undertaken by Barclays in rendering its opinion, is attached to this proxy statement/prospectus as Annex D. The opinion was addressed to, and for the benefit and use of, the Welch Allyn board of directors, was limited to the fairness, from a financial point of view, of the merger consideration, expressed no opinion as to the merits of the underlying decision by Welch Allyn to engage in the merger or the relative merits of the merger as compared to any alternative business strategies, and expressed no opinion or recommendation as to how any Welch Allyn shareholder should vote with respect to the merger or as to whether any Welch Allyn shareholder should authorize a proxy to vote its shares in favor of the adoption of the merger agreement and the approval of the merger.

Accounting Treatment
(see page 74)

        Hill-Rom and Welch Allyn prepare their financial statements in accordance with accounting principles generally accepted in the United States, which are referred to as GAAP in this proxy statement/prospectus. The merger will be accounted for in accordance with FASB ASC Topic 805, Business Combinations, with Hill-Rom considered the accounting acquirer and Welch Allyn as the accounting acquiree. Accordingly, consideration to be given by Hill-Rom to complete the merger with Welch Allyn will be allocated to assets and liabilities of Welch Allyn based on their estimated fair values as of the date of the completion of the merger, with any excess merger consideration being recorded as goodwill.

Exclusivity
(see page 93)

        The merger agreement contains provisions that, among other things, require Welch Allyn to immediately cease existing discussions or negotiations with any person other than Hill-Rom with respect to an acquisition transaction. Additionally, neither Welch Allyn nor any of its affiliates, directors, officers, employees, representatives or agents may, directly or indirectly, solicit, initiate, facilitate or knowingly encourage inquiries or the making of any proposal with respect to an acquisition transaction, or negotiate or otherwise facilitate, encourage, solicit, initiate or engage in discussions, negotiations or submissions of proposals or offers with any person with respect to any acquisition transaction, enter into any written agreement, arrangement, or understanding requiring it to abandon, terminate, or fail to consummate the merger or otherwise cooperate in any way with or assist or participate in, facilitate or encourage, any effort or attempt by any other person to do or seek any of the foregoing.

Termination of the Merger Agreement
(see page 98)

        The merger agreement may be terminated at any time prior to the closing of the merger by mutual written consent of Hill-Rom and Welch Allyn. The merger agreement may also be terminated subject to the limitations set forth in the merger agreement:

•

by Hill-Rom or Welch Allyn:



•

if the merger is not consummated on or before November 30, 2015;



•

if any governmental authority issues an order, decree or ruling or takes any other action permanently enjoining, restraining or otherwise prohibiting the merger that is final and non-appealable; or

if any condition to the obligation of such party to consummate the merger becomes incapable of satisfaction prior to November 30, 2015.



•

by Welch Allyn:



•

if Hill-Rom breaches or fails to perform in any material respect any of its representations, warranties or covenants contained in the merger agreement, which breach or failure to perform (i) would give rise to the failure of a condition to consummate the merger and (ii) cannot be or has not been cured within 30 days of notice from Welch Allyn; and



•

(i) if Hill-Rom fails to complete the merger when required to do so under the merger agreement, (ii) all conditions to closing have been satisfied (other than those conditions that by their terms are to be satisfied at closing) and (iii) Welch Allyn has given written notice to Hill-Rom that it stands ready, willing and able to consummate the merger; or



•

by Hill-Rom if Welch Allyn breaches or fails to perform in any material respect any of its representations, warranties or covenants contained in the merger agreement, which breach or failure to perform (i) would give rise to the failure of a condition to consummate the merger and (ii) cannot be or has not been cured within 30 days of notice from Hill-Rom.

Material United States Federal Income Tax Consequences of the Transaction
(see page 77)

        The receipt of the merger consideration by a U.S holder in exchange for Welch Allyn common stock pursuant to the merger will be a taxable transaction for United States federal income tax purposes. For United States federal income tax purposes, generally you will recognize capital gain or loss as a result of the merger measured by the difference, if any, between the fair market value of the merger consideration (including the sum of cash received, the fair market value (as of the effective time of the merger) of the shares of Hill-Rom common stock received and the value of the right to receive payments pursuant to the escrow that are not treated as interest) and your adjusted tax basis in the shares of Welch Allyn common stock exchanged for the merger consideration in the merger. You may be able to report gain on the installment method.

        You should read the section titled "The Merger—Material United States Federal Income Tax Consequences of the Transaction" beginning on page 77 of this proxy statement/prospectus for a more complete discussion of the United States federal income tax consequences of the merger. Tax matters can be complicated, and the tax consequences of the merger to you will depend on your particular tax situation. Hill-Rom and Welch Allyn urge you to consult your tax advisor to determine the tax consequences of the merger to you.

Comparison of Shareholder Rights
(see page 119)

        Welch Allyn shareholders, whose rights are currently governed by (i) New York law, (ii) Welch Allyn's Amended and Restated Certificate of Incorporation, as amended, which is referred to as the Welch Allyn certificate of incorporation, and (iii) the Amended and Restated By-Laws of Welch Allyn, which are referred to as the Welch Allyn by-laws, will, upon completion of the merger, become Hill-Rom shareholders, and their rights will be governed by (a) Indiana law and (b) Hill-Rom's Amended and Restated Articles of Incorporation and Amended and Restated Code of By-Laws, which are referred to as the Hill-Rom articles of incorporation and the Hill-Rom by-laws, respectively. As a result, Welch Allyn shareholders will have different rights once they become Hill-Rom shareholders due to the differences between the governing documents of Welch Allyn and Hill-Rom. These differences are described in detail in the section titled "Comparison of Shareholder Rights" beginning on page 119 of this proxy statement/prospectus.
