No holder of Stockholder Shares shall grant any proxy or become party to any voting trust or other agreement which is inconsistent with, conflicts with or violates any provision of this Agreement. Section 3. SALE OF THE COMPANY. (a) If, at any time, OEP or the Board concludes that it will solicit a Sale of the Company with any Independent Third Party or group of Independent Third Parties, one or more OEP Directors will consult with one or more Management Directors about plans for such a 4 <Page> solicitation and the Management Directors, on behalf of one or more Investors, shall be permitted to submit proposals relating to a proposed Sale of the Company transaction, which proposal shall indicate the proposed purchase price and other material terms of such transaction, for consideration by OEP or the Board. (b) If, at any time, the Board and the Requisite Majority approve a Sale of the Company to any Independent Third Party or group of Independent Third Parties, each Stockholder shall vote for, consent to and raise no objections against such Sale of the Company; PROVIDED that such transaction complies with the terms of this Agreement, including SECTIONS 3(b) and 3(c) hereof.

Each holder of Stockholder Shares shall take all necessary or desirable actions in connection with the consummation of the Sale of the Company as reasonably requested by the Company. (c) The obligations of the Stockholders with respect to the Sale of the Company are subject to the satisfaction of the following conditions: (i) upon the consummation of the Sale of the Company, each Stockholder shall receive the same form of consideration and the same amount of consideration per share of each class of Stockholder Shares as set forth in SECTION 4 below; (ii) if any holders of a class of Stockholder Shares are given an option as to the form and amount of consideration to be received, each holder of such class of Stockholder Shares shall be given the same option; (iii) no holder of Stockholder Shares shall receive any payments, rights or other benefits not received by all other holders of the class of Stockholder Shares held by such holder, except to the extent that such payments, rights or benefits are provided to such holder otherwise than in its capacity as a holder of Stockholder Shares and are on terms no more favorable than would be given to an unrelated third party in an arm's-length transaction; and (iv) each holder of then currently exercisable rights to acquire shares of a class of Stockholder Shares shall be given an opportunity, at such holder's election, to either (A) exercise such rights prior to the consummation of the Sale of the Company and participate in such sale as holders of such class of Stockholder Shares or (B) upon the consummation of the Sale of the Company, receive in exchange for such rights consideration equal to the amount determined by multiplying (1) the same amount of consideration per share received by holders of such class of Stockholder Shares in connection with the Sale of the Company less the exercise price per share of such class of Stockholder Shares of such rights to acquire such class of Stockholder Shares by (2) the number of shares of such class of Stockholder Shares issuable upon the exercise of such rights. (d) Notwithstanding anything herein to the contrary, in connection with a Sale of the Company (i) each Stockholder will only be required to make representations and warranties as to due organization, good standing, due power and authority, execution, delivery and performance of required documents, non-contravention and ownership of stock (free and clear of all liens), and (ii) each Stockholder shall be severally (and not jointly and severally) obligated to join on a PRO RATA basis (based on its share of the aggregate proceeds paid with respect to its interest) in any indemnification obligation the other Stockholders have agreed to in connection with such Sale of the Company other than any such obligation that relates specifically 5 <Page> to a particular Stockholder, such as indemnification with respect to representations and warranties given by a Stockholder regarding such Stockholder's title to and ownership of stock; PROVIDED HOWEVER, that no Stockholder shall be obligated in connection with such sale to indemnify the prospective transferee or its Affiliates with respect to an amount in excess of the net cash proceeds paid to any such Stockholder, as applicable, in connection with such Sale of the Company (other than as a result of a breach of its representations and warranties described in clause (i) above, as to which no limitation shall apply). Section 4. DISTRIBUTIONS UPON A SALE OF THE COMPANY. In the event of a sale or exchange by the Stockholders of all or substantially all of the Common Stock and Preferred Stock held by the Stockholders (whether by sale, merger, recapitalization, reorganization, consolidation, combination or otherwise), including, without limitation, a Sale of the Company, each Stockholder shall receive in exchange for the shares of each class of Stockholder Shares held by such Stockholder the same portion of the aggregate consideration from such sale or exchange that such Stockholder would have received if such aggregate consideration had been distributed by the Company in complete liquidation pursuant to the rights and preferences of such class of Stockholder Shares set forth in the Company's Articles of Incorporation as in effect immediately prior to such sale or exchange. Each Stockholder shall take all necessary or desirable actions in connection with the distribution of the aggregate consideration from such sale or exchange as requested by the Company. Section 5. INITIAL PUBLIC OFFERING. In the event that the Board approves an Initial Public Offering pursuant to an effective registration statement under the Securities Act, the Stockholders shall take all necessary or desirable actions in connection with the consummation of the Initial Public Offering as the Board may reasonably request in connection therewith. In the event that the Initial Public Offering is an underwritten offering and the managing underwriters advise the Company in writing that in their opinion the Company's capital stock structure would adversely affect the marketability of the Initial Public Offering, each Stockholder shall consent to and vote for a recapitalization, reorganization and/or exchange of Common Stock and/or Preferred Stock into securities that the managing underwriters and the Board find acceptable and shall take all necessary or desirable actions in connection with the consummation of such recapitalization, reorganization and/or exchange; PROVIDED that such action does not materially and adversely affect the relative rights of any class of Stockholder Shares in a manner different than any other class of Stockholder Shares. Section 6. RESTRICTIONS ON TRANSFER OF STOCKHOLDER SHARES. (a) FIRST REFUSAL RIGHTS. (i) At least fifteen (15) days prior to any Transfer of Stockholder Shares (other than (i) a Transfer pursuant to a Public Sale, (ii) a Transfer to the Company, (iii) a Transfer to another Stockholder or his, her or its Permitted Transferees, (iv) a Transfer to a Permitted Transferee, (v) redemptions of Preferred Stock pursuant to the Company's Articles of Incorporation, or (vi) a Transfer pursuant to SECTIONS 3 or 6) by an Investor or its Permitted Transferees (a "TRANSFERRING HOLDER"), such Transferring Holder shall first offer to sell such Transferring Holder's Stockholder Shares by delivering a written notice (the "TRANSFER NOTICE") to the Company, the Investors other than the 6 <Page> Transferring Holder, OEP and OEP's Permitted Transferees that have become Stockholders hereunder, specifying in reasonable detail the number and class of shares to be Transferred, the identity of the prospective transferee(s), the closing date for the proposed Transfer, which date shall not be earlier than forty-five (45) days from the date of the Transfer Notice, and all material terms and conditions of the Transfer, which terms and conditions shall have been agreed upon by the prospective transferee(s). The Investors other than the Transferring Holder, on a pro-rata basis (calculated as a percentage, the numerator of which is the number of Stockholder Shares then held by the Investor electing to participate and the denominator of which is the total number of Stockholder Shares held by all the participating Investors), may elect to purchase all or any portion of the Stockholder Shares to be transferred at the same price and on the same terms as such Stockholder Shares are to be offered to such other Persons by delivering written notice to the Transferring Holder, the Investors other than the Transferring Holder, OEP and to OEP's Permitted Transferees that have become Stockholders hereunder within fifteen (15) days after delivery of the Transfer Notice. If for any reason the Investors other than the Transferring Holder do not elect to purchase all of the Stockholder Shares to be transferred, the Company shall be entitled to purchase all of the Stockholder Shares which the Investors other than the Transferring Holder have not elected to purchase (the "AVAILABLE SECURITIES") at the same price and on the same terms as such Available Securities are to be offered to such other Persons by giving written notice of such election to the Investors other than the Transferring Holder, to OEP and to OEP's Permitted Transferees that have become Stockholders hereunder and to the Transferring Holder within thirty (30) days after delivery of the Transfer Notice. If for any reason the Investors other than the Transferring Holder and the Company do not elect to purchase all of the Stockholder Shares to be transferred, OEP shall be entitled to purchase all of the Available Securities at the same price and on the same terms as such Available Securities are to be offered to such other Persons by giving written notice of such election to the Investors other than the Transferring Holder and to the Transferring Holder and the Company within forty-five (45) days after delivery of the Transfer Notice. (ii) The consummation of the Transfer under SECTION 6(a)(i) above shall take place at 10:00 a.m. local time at the offices of the Company, on the earlier of (x) date specified for the proposed Transfer in the notice from the applicable purchaser accepting the offer set forth in the Transfer Notice, or (y) the closing date specified by the Transferring Holder in the Transfer Notice, at which time the purchaser shall deliver the appropriate consideration, and the Transferring Holder shall deliver certificates (or an affidavit of lost certificate, as appropriate) representing the Stockholder Shares to be sold, free and clear of any and all liens, claims and encumbrances whatsoever (except those imposed by this Agreement and federal and any applicable state securities laws generally), together with such other instruments and documents of transfer as the purchaser shall reasonably request. (iii) If the Investors other than the Transferring Holder and/or the Company, OEP and OEP Permitted Transferees do not elect to purchase, collectively, all of the Stockholder Shares specified in the Transfer Notice, then the Transferring Holder may transfer all of the Stockholder Shares specified in the Transfer Notice to the transferee(s) identified in the Transfer Notice for (x) a price no less than the price 7 <Page> specified in the Transfer Notice and (y) other terms no more favorable to the transferee(s) thereof than specified in the Transfer Notice, during the 120-day period immediately following the date on which the Transfer Notice has been given to the Company, the Investors other than the Transferring Holder, OEP and OEP's Permitted Transferees. Any Stockholder Shares not transferred within such 90-day period will be subject to the provisions of this SECTION 6(a) upon subsequent Transfer. (b) PARTICIPATION RIGHTS. At least thirty (30) days prior to any Transfer of Stockholder Shares by OEP or by any Permitted Transferee of OEP that has become a Stockholder hereunder (each, a "SIGNIFICANT STOCKHOLDER") (other than (i) pursuant to a Public Sale, (ii) a Transfer to any Permitted Transferee(s), (iii) an Exempt Transfer, or (iv) redemptions of Preferred Stock pursuant to the Company's Articles of Incorporation), the transferring Significant Stockholder shall deliver a written notice (the "TAG-ALONG SALE NOTICE") to the Company and each other Stockholder, including the other Significant Stockholders (the "OTHER STOCKHOLDERS"), specifying in reasonable detail the identity of the prospective transferee(s), the number and the class of shares to be Transferred and the terms and conditions of the Transfer. In the event that any of the Other Stockholders hold the class of Stockholder Shares which are to be transferred, such Other Stockholders may elect to participate in the contemplated Transfer by delivering written notice to the transferring Significant Stockholder within fifteen (15) days after delivery of the Tag-Along Sale Notice. If any Other Stockholders elect to participate in such Transfer (each a "PARTICIPATING STOCKHOLDER"), and any of the Stockholder Shares specified in the Tag-Along Sale Notice are shares of Common Stock, the transferring Significant Stockholder and each Participating Stockholder shall be entitled to sell in the contemplated Transfer, at the same price and on the same terms, a number of shares of Common Stock equal to the product of (i) the quotient determined by dividing the percentage of shares of Common Stock held by such Stockholder by the aggregate percentage of shares of Common Stock held by the transferring Significant Stockholder and all Participating Stockholders participating in such Transfer and (ii) the number of shares of Common Stock to be sold in the contemplated Transfer. All such determinations of the number of shares and percentage of Common Stock made under this SECTION 6(b) shall be made on a fully-diluted basis. FOR EXAMPLE, if the Tag-Along Sale Notice contemplated a sale of 100 shares of Common Stock by the transferring Significant Stockholder, and if the transferring Significant Stockholder at such time owns 30% of the total number of outstanding shares of Common Stock and if one Participating Stockholder elects to participate and such Stockholder owns 20% of the total number of outstanding shares of Common Stock, the transferring Significant Stockholder would be entitled to sell 60 shares (30% DIVIDED BY 50% x 100) and the Participating Stockholder would be entitled to sell 40 shares (20% DIVIDED BY 50% x 100). If any of the Stockholder Shares specified in the Tag-Along Sale Notice consists of any class of Preferred Stock, the transferring Significant Stockholder and each Participating Stockholder shall be entitled to sell in the contemplated Transfer, at the same price and on the same terms, a number of shares of any class of Preferred Stock held by such Stockholder equal to the aggregate number of shares of Preferred Stock to be Transferred multiplied by a fraction, the numerator of which is the liquidation value (plus accrued and unpaid dividends thereon) of such 8 <Page> shares of any class of Preferred Stock owned by such Participating Stockholder and the denominator of which is the liquidation value (plus accrued and unpaid dividends thereon) of such shares of all classes of Preferred Stock owned by all holders participating in such transaction. FOR EXAMPLE, if the Tag-Along Sale Notice contemplated a sale of 100 shares of Preferred Stock by the transferring Significant Stockholder and if the Preferred Stock owned by the transferring Significant Stockholder had a liquidation value (plus accrued and unpaid dividends thereon) of $1,080,000 and if one other holder elects to participate and the Preferred Stock owned by such electing holder has a liquidation value (plus accrued and unpaid dividends thereon) of $2,160,000, the transferring Significant Stockholder would be entitled to sell 33 1/3 shares of Preferred Stock ((1,080,000 / 3,240,000) * 100 shares) and the electing holder would be entitled to sell 66 2/3 shares ((2,160,000 / 3,240,000) * 100 shares) of Preferred Stock. The transferring Significant Stockholder shall use its reasonable best efforts to obtain the agreement of the prospective transferee(s) to the participation of the Participating Stockholders in any contemplated Transfer, and the transferring Significant Stockholder shall not Transfer any of its Stockholder Shares of such class to the prospective transferee(s) unless (1) the prospective transferee(s) agrees to allow the participation of the Participating Stockholders or (2) the transferring Significant Stockholder agrees to purchase the number of such class of Stockholder Shares from any Participating Stockholders which the Participating Stockholders would have been entitled to sell (and at the price it would have received) pursuant to this SECTION 6(b). If any securities convertible, exchangeable or exercisable for any class of Stockholder Shares (or securities into which any class of Stockholder Shares are convertible, exchangeable or exercisable) are included in any Transfer under this SECTION 6(b), the purchase price for such securities shall be equal to the full purchase price determined hereunder for the Stockholder Shares covered by the portion of such securities to be transferred, reduced by the aggregate exercise price for such shares. Each Stockholder transferring Stockholder Shares pursuant to this SECTION 6(b) shall pay its PRO RATA share (based on the aggregate consideration to be received with respect to each class of stock to be sold, taking into account the relative preferences and priorities of the shares to be sold) of reasonable expenses incurred by the Stockholders in connection with such Transfer (other than transaction fees paid to the transferring Significant Stockholder or its Affiliates) and shall be obligated, on a several (and not on a joint and several) basis, to join on a PRO RATA basis (based on the aggregate consideration to be received with respect to each class of stock to be sold) in any representations, warranties, indemnification provisions or other obligations (including, without limitation, any escrow arrangements) that the transferring Significant Stockholder agrees to provide in connection with such Transfer (other than any such obligations that relate specifically to a particular Stockholder such as indemnification with respect to representations and warranties given by a Stockholder regarding such Stockholder's title to and ownership of Stockholder Shares); PROVIDED that no holder shall be obligated in connection with such Transfer to agree to indemnify or hold harmless the transferee(s) with respect to an amount in excess of the net cash proceeds paid to such holder in connection with 9 <Page> such Transfer. If any Transfer is not consummated on the same terms and conditions as set forth in the Tag-Along Sale Notice within ninety (90) days after the expiration of the notice periods described above, the transferring Significant Stockholder shall again comply with the terms of this SECTION 6(b) with respect to such Transfer. (c) PERMITTED TRANSFERS. The restrictions contained in this SECTION 6 shall not apply with respect to any Transfer of Stockholder Shares by any Stockholder (i) in the case of a Stockholder who is an individual, pursuant to applicable laws of descent and distribution or among such individual's Family Group, to any estate planning trust of a Stockholder established for the sole benefit of such individual's Family Group, provided that the grantor Stockholder is the trustee of such trust, to any family limited partnership or family limited liability company of which the grantor Stockholder is and must remain a controlling Person with respect to the voting and the disposition of the Stockholder Shares held thereby or to such other personal estate or tax planning vehicle or device of which the grantor Stockholder is a controlling Person with respect to the voting and the disposition of the Stockholder Shares held thereby, (ii) in the case of a Stockholder which is not an individual, among such entity's Affiliates (for the purposes hereof, the Company shall not be deemed to be an Affiliate of any Stockholder), (iii) in the case of OEP and its Permitted Transferees, if such Transfer constitutes an in-kind distribution to its members of their respective PRO RATA interest in the Stockholder Shares so Transferred and any subsequent Transfer by such members constituting an in-kind distribution to the equity owners of any such member of such equity owner's PRO RATA interest in the Stockholder Shares held by such member and (iv) in the case of Stockholder Shares owned or held by any Deferred Compensation Plan, any distribution or Transfer to the beneficiaries of such Deferred Compensation Plan; PROVIDED that the restrictions contained in this SECTION 6 shall continue to be applicable to the Stockholder Shares after any of the foregoing Transfers, and PROVIDED FURTHER that the transferees of such Stockholder Shares shall have entered into a Joinder Agreement and agreed in writing to be bound by the provisions of this Agreement which affect the Stockholder Shares so transferred. All transferees permitted under this SECTION 6(c) are collectively referred to herein as "PERMITTED TRANSFEREES." Each Permitted Transferee shall be deemed a Stockholder for purposes of this Agreement. (d) COUNTERPARTS. Prior to and in connection with any Transfer of any Stockholder Shares (other than pursuant to a Public Sale or a Sale of the Company) to any Person, the holder(s) of Stockholder Shares seeking to Transfer such Stockholder Shares shall cause the prospective transferee to execute a Joinder Agreement pursuant to which such transferee agrees to be bound by the provisions of this Agreement affecting the Stockholder Shares so Transferred. (e) REPURCHASE ON TERMINATION OF EMPLOYMENT. The Parties acknowledge that each of the Investors is presently an employee of Medex. Notwithstanding anything contained in this Agreement to the contrary, in the event that an Investor's employment with Medex shall: (i) be terminated by the Company for Cause or by the Investor's voluntary resignation without Good Reason, then, during the period of six (6) months commencing on the date of termination of employment, the Company shall have the right, but not the obligation, to repurchase all, but not less than all, of the Stockholder 10 <Page> Shares held by such Investor and any Permitted Transferee who holds Stockholder Shares transferred, directly or indirectly, by such Investor (a "CALL RIGHT"). The Company shall provide a notice within the six (6) month period identified above of its election to exercise its Call Right under this subsection (i) to the Investor (the "REPURCHASE NOTICE"), which Repurchase Notice shall set forth the closing date for the repurchase of Stockholder Shares. The repurchase price for all Stockholder Shares repurchased pursuant to this subsection (i) shall be the Appraised Value of such shares at the time of repurchase. Payment for such Stockholder Shares shall be made by the Company in a single lump sum payment of cash on the closing date set forth in the Repurchase Notice, PROVIDED HOWEVER, that, the Stockholder Shares shall be deemed to have been redeemed on such closing date but no payment shall be due and payable unless and until the Investor and his or her Permitted Transferees shall deliver to the Company the certificates for the repurchased Stockholder Shares (or affidavit of lost certificate, as applicable), together with a certificate, in form reasonably satisfactory to the Company, certifying that such shares are free and clear of all liens and encumbrances. (ii) be terminated as a result of the death or Disability of the Investor, the Company shall repurchase all, but not less than all, of the Stockholder Shares held by such Investor and any Permitted Transferee who holds Stockholder Shares transferred, directly or indirectly, by such Investor; PROVIDED, HOWEVER, the Company shall not be obligated to repurchase any Stockholder Shares pursuant to this subsection (ii) during the period in which such repurchase would violate any term or condition contained in, or result in a default or potential event of default under, any agreement relating to or governing the Company's outstanding indebtedness for borrowed money, including without limitation, the Senior Credit Agreement and the Indenture. The repurchase price for all Stockholder Shares repurchased pursuant to this subsection (ii) shall be the Appraised Value of such shares at the time of repurchase, which repurchase shall be consummated within ninety (90) days of such death or disability. Payment for such Stockholder Shares shall be made by the Company in a single lump sum payment of cash on the closing date, PROVIDED HOWEVER, the Stockholder Shares shall be deemed to have been redeemed on such closing date but no payment shall be due and payable unless and until the Investor (or executor) and his or her Permitted Transferees shall deliver to the Company the certificates for the repurchased Stockholder Shares (or affidavit of lost certificate, as applicable), together with a certificate, in form reasonably satisfactory to the Company, certifying that such shares are free and clear of all liens and encumbrances. Notwithstanding anything to the contrary herein, the Company's repurchase obligation under this subsection (ii) with respect to any Investor who is a Senior Executive shall be limited to such number of Stockholder Shares not exceeding $5,000,000 in value (with any remaining Stockholder Shares to be retained by the Senior Executive or his Permitted Transferees, as applicable). (iii) be terminated by the Company without Cause or by the Investor for Good Reason, then, during the period of six (6) months commencing on the date of termination of employment, (x) the Investor, including a Senior Executive, shall have the option, but not the obligation, to sell to the Company and cause the Company to repurchase all, but not less than all, of the Stockholder Shares held by such Investor and any Permitted Transferee who holds Stockholder Shares transferred, directly or 11 <Page> indirectly, by such Investor (a "PUT RIGHT") and (y) in the case of an Investor other than a Senior Executive, the Company shall have a Call Right to repurchase all, but not less than all, of the Stockholder Shares held by such Investor and any Permitted Transferee who holds Stockholder Shares transferred, directly or indirectly, by such Investor.
