 Exhibit 4.2 
  

ACCREDO HEALTH, INCORPORATED 
 1999
LONG-TERM INCENTIVE PLAN 
  
 ARTICLE I 
 PURPOSE 
  
 1.1. GENERAL. The purpose of the Accredo Health, Incorporated 1999 Long-Term Incentive Plan (the “Plan”) is to promote the success, and
enhance the value, of Accredo Health, Incorporated (the “Corporation”), by linking the personal interests of its employees, officers, consultants and directors to those of Corporation stockholders and by providing such persons with an
incentive for outstanding performance. The Plan is further intended to provide flexibility to the Corporation in its ability to motivate, attract, and retain the services of employees, officers, consultants and directors upon whose judgment,
interest, and special effort the successful conduct of the Corporation’s operation is largely dependent. Accordingly, the Plan permits the grant of incentive awards from time to time to selected employees, officers, directors, and consultants;
provided, however, to the extent necessary to preserve the employee benefits plan exemption under applicable state blue sky laws, no non-employee director or consultant of the Corporation will be eligible to receive Awards under the Plan until such
time, if any, as the Corporation’s common stock shall be traded on a national securities exchange or on the Nasdaq National Market. 
  
 ARTICLE 2 
 EFFECTIVE DATE

  
 2.1. EFFECTIVE DATE. The Plan shall be effective as
of the date upon which it shall be approved by the Board. However, the Plan shall be submitted to the stockholders of the Corporation for approval within 12 months of the Board’s approval thereof. No Incentive Stock Options granted under the
Plan may be exercised prior to approval of the Plan by the stockholders and if the stockholders fail to approve the Plan within 12 months of the Board’s approval thereof, any Incentive Stock Options previously granted hereunder shall be
automatically converted to Non-Qualified Stock Options without any further act. In the discretion of the Committee, Awards may be made to Covered Employees which are intended to constitute qualified performance-based compensation under Code Section
162(m). Any such Awards shall be contingent upon the stockholders having approved the Plan.

and accounting effects of such an exchange. 
  
 13.3. TERM OF
AWARD. The term of each Award shall be for the period as determined by the Committee, provided that in no event shall the term of any Incentive 

  

 - 13 - 

 
Stock Option or a Stock Appreciation Right granted in tandem with the Incentive Stock Option exceed a period of ten years from the date of its grant (or, if
Section 7.2(e) applies, five years from the date of its grant). 
  
 13.4. FORM OF PAYMENT FOR AWARDS. Subject to the terms of the Plan and any applicable law or Award Agreement, payments or transfers to be made by the Corporation or a Parent or Subsidiary on the grant or exercise of an Award may be
made in such form as the Committee determines at or after the time of grant, including without limitation, cash, Stock, other Awards, or other property, or any combination, and may be made in a single payment or transfer, in installments, or on a
deferred basis, in each case determined in accordance with rules adopted by, and at the discretion of, the Committee. 
  
 13.5. LIMITS ON TRANSFER. No right or interest of a Participant in any unexercised or restricted Award may be pledged, encumbered, or hypothecated
to or in favor of any party other than the Corporation or a Parent or Subsidiary, or shall be subject to any lien, obligation, or liability of such Participant to any other party other than the Corporation or a Parent or Subsidiary. No unexercised
or restricted Award shall be assignable or transferable by a Participant other than by will or the laws of descent and distribution or, except in the case of an Incentive Stock Option, pursuant to a domestic relations order that would satisfy
Section 414(p)(1)(A) of the Code if such Section applied to an Award under the Plan; provided, however, that the Committee may (but need not) permit other transfers where the Committee concludes that such transferability (i) does not result in
accelerated taxation, (ii) does not cause any Option intended to be an incentive stock option to fail to be described in Code Section 422(b), and (iii) is otherwise appropriate and desirable, taking into account any factors deemed relevant,
including without limitation, any state or federal tax or securities laws or regulations applicable to transferable Awards. 
  
 13.6. STOCK CERTIFICATES. All Stock certificates delivered under the Plan are subject to any stop-transfer orders and other restrictions as the
Committee deems necessary or advisable to comply with federal or state securities laws, rules and regulations and the rules of any national securities exchange or automated quotation system on which the Stock is listed, quoted, or traded. The
Committee may place legends on any Stock certificate to reference restrictions applicable to the Stock. 
  
 13.7. ACCELERATION UPON DEATH, RETIREMENT OR DISABILITY. Notwithstanding any other provision in the Plan or any Participant’s Award Agreement
to the contrary, upon the Participant’s death, Retirement or Disability during his employment or service as a consultant or director, all outstanding Options, Stock Appreciation Rights, and other Awards in the nature of rights that may be
exercised shall become fully exercisable and all restrictions on outstanding Awards shall lapse. Any Option or Stock Appreciation Rights Awards shall thereafter continue or lapse in accordance with the other provisions of the Plan and the Award
Agreement. To the extent that this provision causes Incentive Stock Options to exceed the dollar limitation set forth in Section 7.2(d), the excess Options shall be deemed to be Non-Qualified Stock Options. 
  

 - 14 - 

 13.8. ACCELERATION UPON A CHANGE IN CONTROL. Except as otherwise provided in the Award Agreement,
upon the occurrence of a Change in Control, all outstanding Options, Stock Appreciation Rights, and other Awards in the nature of rights that may be exercised shall become fully exercisable and all restrictions on outstanding Awards shall lapse;
provided, however that such acceleration will not occur if, in the opinion of the Corporation’s accountants, such acceleration would preclude the use of “pooling of interest” accounting treatment for a Change in Control transaction
that (a) would otherwise qualify for such accounting treatment, and (b) is contingent upon qualifying for such accounting treatment. To the extent that this provision causes Incentive Stock Options to exceed the dollar limitation set forth in
Section 7.2(d), the excess Options shall be deemed to be Non-Qualified Stock Options. 
  
 13.9. ACCELERATION UPON CERTAIN EVENTS NOT CONSTITUTING A CHANGE IN CONTROL. In the event of the occurrence of any circumstance, transaction or event not constituting a Change in Control (as defined in Section
3.1) but which the Board of Directors deems to be, or to be reasonably likely to lead to, an effective change in control of the Corporation of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of the 1934 Act,
the Committee may in its sole discretion declare all outstanding Options, Stock Appreciation Rights, and other Awards in the nature of rights that may be exercised to be fully exercisable, and/or all restrictions on all outstanding Awards to have
lapsed, in each case, as of such date as the Committee may, in its sole discretion, declare, which may be on or before the consummation of such transaction or event. To the extent that this provision causes Incentive Stock Options to exceed the
dollar limitation set forth in Section 7.2(d), the excess Options shall be deemed to be Non-Qualified Stock Options. 
  
 13.10. ACCELERATION FOR ANY OTHER REASON. Regardless of whether an event has occurred as described in Section 13.8 or 13.9 above, the Committee may
in its sole discretion at any time determine that all or a portion of a Participant’s Options, Stock Appreciation Rights, and other Awards in the nature of rights that may be exercised shall become fully or partially exercisable, and/or that
all or a part of the restrictions on all or a portion of the outstanding Awards shall lapse, in each case, as of such date as the Committee may, in its sole discretion, declare. The Committee may discriminate among Participants and among Awards
granted to a Participant in exercising its discretion pursuant to this Section 13.10. 
  
 13.11. EFFECT OF ACCELERATION. If an Award is accelerated under Section 13.8 or 13.9, the Committee may, in its sole discretion, provide (i) that the Award will expire after a designated period of time after
such acceleration to the extent not then exercised, (ii) that the Award will be settled in cash rather than Stock, (iii) that the Award will be assumed by another party to the transaction giving rise to the acceleration or otherwise be equitably
converted in connection with such transaction, or (iv) any combination of the foregoing. The Committee’s determination need not be uniform and may be different for different Participants whether or not such Participants are similarly situated.

  

 - 15 - 

 13.12. PERFORMANCE GOALS. The Committee may (but need not) determine that any Award granted
pursuant to this Plan to a Participant (including, but not limited to, Participants who are Covered Employees) shall be determined solely on the basis of (a) the achievement by the Corporation or a Parent or Subsidiary of a specified target return,
or target growth in return, on equity or assets, (b) the Company’s total shareholder return (stock price appreciation plus reinvested dividends) relative to a defined comparison group or target over a specific performance period, (c) the
Corporation’s, Parent’s or Subsidiary’s stock price, (d) the achievement by an individual or a business unit of the Corporation, Parent or Subsidiary of a specified target, or target growth in, revenues, net income or earnings per
share, (e) the achievement of objectively determinable goals with respect to service or product delivery, service or product quality, customer satisfaction, meeting budgets and/or retention of employees or (f) any combination of the goals set forth
in (a) through (e) above. If an Award is made on such basis, the Committee shall establish goals prior to the beginning of the period for which such performance goal relates (or such later date as may be permitted under Code Section 162(m) or the
regulations thereunder) and the Committee may for any reason reduce (but not increase) any Award, notwithstanding the achievement of a specified goal. Any payment of an Award granted with performance goals shall be conditioned on the written
certification of the Committee in each case that the performance goals and any other material conditions were satisfied. 
  
 13.13. TERMINATION OF EMPLOYMENT. Whether military, government or other service or other leave of absence shall constitute a termination of
employment shall be determined in each case by the Committee at its discretion, and any determination by the Committee shall be final and conclusive. A termination of employment shall not occur in a circumstance in which a Participant transfers from
the Corporation to one of its Parents or Subsidiaries, transfers from a Parent or Subsidiary to the Corporation, or transfers from one Parent or Subsidiary to another Parent or Subsidiary. 
  
 ARTICLE 14 
 CHANGES IN CAPITAL STRUCTURE 
  
 14.1. GENERAL. In the event a stock dividend is declared upon the Stock, the authorization limits under Section 5.1 and 5.4 shall be increased proportionately, and the shares of Stock then subject to each Award
shall be increased proportionately without any change in the aggregate purchase price therefor. In the event the Stock shall be changed into or exchanged for a different number or class of shares of stock or securities of the Corporation or of
another corporation, whether through reorganization, recapitalization, reclassification, share exchange, stock split-up, combination of shares, merger or consolidation, the authorization limits under Section 5.1 and 5.4 shall be increased
proportionately, and there shall be substituted for each such share of Stock then subject to each Award the number and class of shares into which each outstanding share of Stock 

  

 - 16 - 

 
shall be so exchanged, all without any change in the aggregate purchase price for the shares then subject to each Award, or, subject to Section 15.2, there
shall be made such other equitable adjustment as the Committee shall approve. 
  
 ARTICLE 15 
 AMENDMENT, MODIFICATION AND TERMINATION 
  
 15.1. AMENDMENT, MODIFICATION AND TERMINATION. The Board or the
Committee may, at any time and from time to time, amend, modify or terminate the Plan without stockholder approval; provided, however, that the Board or Committee may condition any amendment or modification on the approval of stockholders of the
Corporation if such approval is necessary or deemed advisable with respect to tax, securities or other applicable laws, policies or regulations. 
  
 15.2. AWARDS PREVIOUSLY GRANTED. At any time and from time to time, the Committee may amend, modify or terminate any outstanding Award without
approval of the Participant; provided, however, that, subject to the terms of the applicable Award Agreement, such amendment, modification or termination shall not, without the Participant’s consent, reduce or diminish the value of such Award
determined as if the Award had been exercised, vested, cashed in or otherwise settled on the date of such amendment or termination. No termination, amendment, or modification of the Plan shall adversely affect any Award previously granted under the
Plan, without the written consent of the Participant. 
  
 ARTICLE 16 
 GENERAL PROVISIONS 
  
 16.1. NO RIGHTS TO AWARDS. No Participant or any eligible participant shall have any claim to be granted any Award
under the Plan, and neither the Corporation nor the Committee is obligated to treat Participants or eligible participants uniformly. 
  
 16.2. NO STOCKHOLDER RIGHTS. No Award gives the Participant any of the rights of a stockholder of the Corporation unless and until shares of Stock
are in fact issued to such person in connection with such Award. 
  
 16.3. WITHHOLDING. The Corporation or any Parent or Subsidiary shall have the authority and the right to deduct or withhold, or require a Participant to remit to the Corporation, an amount sufficient to satisfy federal, state, and
local taxes (including the Participant’s FICA obligation) required by law to be withheld with respect to any taxable event arising as a result of the Plan. With respect to withholding required upon any taxable event under the Plan, the
Committee may, at the time the Award is granted or thereafter, require that any such withholding requirement be satisfied, in whole or in part, by withholding shares of Stock having a Fair Market Value on the date of withholding equal to the amount
required to be withheld for tax purposes, all in accordance with such procedures as the Committee establishes. 
  

 - 17 - 

 16.4. NO RIGHT TO CONTINUED SERVICE. Nothing in the Plan or any Award Agreement shall interfere
with or limit in any way the right of the Corporation or any Parent or Subsidiary to terminate any Participant’s employment or status as an officer, director or consultant at any time, nor confer upon any Participant any right to continue as an
employee, officer, director or consultant of the Corporation or any Parent or Subsidiary. 
  
 16.5. UNFUNDED STATUS OF AWARDS. The Plan is intended to be an “unfunded” plan for incentive and deferred compensation. With respect to any payments not yet made to a Participant pursuant to an Award,
nothing contained in the Plan or any Award Agreement shall give the Participant any rights that are greater than those of a general creditor of the Corporation or any Parent or Subsidiary. 
  
 16.6. INDEMNIFICATION. To the extent allowable under applicable law,
each member of the Committee shall be indemnified and held harmless by the Corporation from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by such member in connection with or resulting from any claim, action,
suit, or proceeding to which such member may be a party or in which he may be involved by reason of any action or failure to act under the Plan and against and from any and all amounts paid by such member in satisfaction of judgment in such action,
suit, or proceeding against him provided he gives the Corporation an opportunity, at its own expense, to handle and defend the same before he undertakes to handle and defend it on his own behalf. The foregoing right of indemnification shall not be
exclusive of any other rights of indemnification to which such persons may be entitled under the Corporation’s Certificate of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that the Corporation may have to indemnify
them or hold them harmless. 
  
 16.7. RELATIONSHIP TO OTHER
BENEFITS. No payment under the Plan shall be taken into account in determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or benefit plan of the Corporation or any Parent or Subsidiary unless
provided otherwise in such other plan. 
  
 16.8. EXPENSES.
The expenses of administering the Plan shall be borne by the Corporation and its Parents or Subsidiaries. 
  
 16.9. TITLES AND HEADINGS. The titles and headings of the Sections in the Plan are for convenience of reference only, and in the event of any
conflict, the text of the Plan, rather than such titles or headings, shall control. 
  
 16.10. GENDER AND NUMBER. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine; the plural shall include the singular and the singular shall include
the plural. 
  

 - 18 - 

 16.11. FRACTIONAL SHARES. No fractional shares of Stock shall be issued and the Committee shall
determine, in its discretion, whether cash shall be given in lieu of fractional shares or whether such fractional shares shall be eliminated by rounding up. 
  
 16.12. GOVERNMENT AND OTHER REGULATIONS. The obligation of the Corporation to make payment of awards in Stock or otherwise shall be subject to all
applicable laws, rules, and regulations, and to such approvals by government agencies as may be required. The Corporation shall be under no obligation to register under the 1933 Act, or any state securities act, any of the shares of Stock paid under
the Plan. The shares paid under the Plan may in certain circumstances be exempt from registration under the 1933 Act, and the Corporation may restrict the transfer of such shares in such manner as it deems advisable to ensure the availability of any
such exemption. 
  
 16.13. GOVERNING LAW. To the extent not
governed by federal law, the Plan and all Award Agreements shall be construed in accordance with and governed by the laws of the State of Tennessee. 
  
 16.14 ADDITIONAL PROVISIONS. Each Award Agreement may contain such other terms and conditions as the Committee may determine; provided that such
other terms and conditions are not inconsistent with the provisions of this Plan. 
  
 16.15 CODE SECTION 162(m). The deduction limits of Code Section 162(m) and the regulation thereunder do not apply to the Corporation until such time, if any, as any class of the Corporation’s common equity
securities is registered under Section 12 of the 1934 Act or the Corporation otherwise meets the definition of a “publicly held corporation” under Treasury Regulation 1.162-27(c) or any successor provision. Upon becoming a publicly held
corporation, the deduction limits of Code Section 162(m) and the regulations thereunder shall not apply to compensation payable under this Plan until the expiration of the reliance period described in Treasury Regulation 1.162-27(f) or any successor
regulation. 
  
 The foregoing is hereby acknowledged as being the
Accredo Health, Incorporated 1999 Long-Term Incentive Plan as adopted by the Board of Directors of the Corporation on April     , 1999 and approved by the stockholders of the Corporation on

may be exercised or vested. The Committee may waive any exercise or vesting provisions at any time in whole or in part based upon factors as the Committee may determine in its sole discretion so that the Option becomes exercisable or vested at an
earlier date. The Committee may permit an arrangement whereby receipt of Stock upon exercise of an Option is delayed until a specified future date. 
  
 (c) PAYMENT. The Committee shall determine the methods by which the exercise price of an Option may be paid, the form of payment,
including, without limitation, cash, shares of Stock, or other property (including “cashless exercise” arrangements), and the methods by which shares of Stock shall be delivered or deemed to be delivered to Participants; provided, however,
that if shares of Stock are used to pay the exercise price of an Option, such shares must have been held by the Participant for at least six months. 
  
 (d) EVIDENCE OF GRANT. All Options shall be evidenced by a term sheet summarizing the terms and conditions of the Award. The summary shall
include such provisions, not inconsistent with the Plan, as may be specified by the Committee. 
  
 (e) EXERCISE TERM. In no event may any Option be exercisable for more than ten years from the date of its grant. 
  

 - 8 - 

 7.2. INCENTIVE STOCK OPTIONS. The terms of any Incentive Stock Options granted under the Plan must comply
with the following additional rules: 
  
 (a)
EXERCISE PRICE. The exercise price per share of Stock shall be set by the Committee, provided that the exercise price for any Incentive Stock Option shall not be less than the Fair Market Value as of the date of the grant. 
  
 (b) EXERCISE. In no event may any Incentive Stock Option be
exercisable for more than ten years from the date of its grant. 
  
 (c) LAPSE OF OPTION. An Incentive Stock Option shall lapse under the earliest of the following circumstances; provided, however, that the Committee may, prior to the lapse of the Incentive Stock Option under the
circumstances described in paragraphs (3), (4) and (5) below, provide in writing that the Option will extend until a later date, but if the Option is exercised after the dates specified in paragraphs (3), (4) and (5) below, it will automatically
become a Non-Qualified Stock Option: 
  
 (1) The
Incentive Stock Option shall lapse as of the option expiration date set forth in the Award summary. 
  
 (2) The Incentive Stock Option shall lapse ten years after it is granted, unless an earlier time is set in the Award Agreement.

  
 (3) If the Participant terminates employment
for any reason other than as provided in paragraph (4) or (5) below, the Incentive Stock Option shall lapse, unless it is previously exercised, three months after the Participant’s termination of employment; provided, however, that if the
Participant’s employment is terminated by the Corporation for Cause or by the Participant without the consent of the Corporation, the Incentive Stock Option shall (to the extent not previously exercised) lapse immediately. 
  
 (4) If the Participant terminates employment by reason of
his Disability, the Incentive Stock Option shall lapse, unless it is previously exercised, one year after the Participant’s termination of employment. 
  
 (5) If the Participant dies while employed, or during the three-month period described in paragraph (3) or during the one-year period
described in paragraph (4) and before the Option otherwise lapses, the Option shall lapse one year after the Participant’s death. Upon the Participant’s death, any exercisable Incentive Stock Options may be exercised by the
Participant’s beneficiary, determined in accordance with Section 9.5. 
  
 Unless the exercisability of the Incentive Stock Option is accelerated as provided in Article 9, if a Participant exercises an Option after termination of employment, the Option may be exercised only with respect to
the shares that were otherwise vested on the Participant’s termination of employment. 
  

 - 9 - 

 (d) INDIVIDUAL DOLLAR LIMITATION. The aggregate Fair Market Value (determined as of the
time an Award is made) of all shares of Stock with respect to which Incentive Stock Options are first exercisable by a Participant in any calendar year may not exceed $100,000.00. 
  
 (e) TEN PERCENT OWNERS. No Incentive Stock Option shall be granted to any individual who, at the date of
grant, owns stock possessing more than ten percent of the total combined voting power of all classes of stock of the Corporation or any Parent or Subsidiary unless the exercise price per share of such Option is at least 110% of the Fair Market Value
per share of Stock at the date of grant and the Option expires no later than five years after the date of grant. 
  
 (f) EXPIRATION OF INCENTIVE STOCK OPTIONS. No Award of an Incentive Stock Option may be made pursuant to the Plan after the day
immediately prior to the tenth anniversary of the Effective Date. 
  
 (g) RIGHT TO EXERCISE. During a Participant’s lifetime, an Incentive Stock Option may be exercised only by the Participant or, in the case of the Participant’s Disability, by the Participant’s guardian
or legal representative. 
  
 (h) DIRECTORS. The
Committee may not grant an Incentive Stock Option to a non-employee director. The Committee may grant an Incentive Stock Option to a director who is also an employee of the Corporation or Parent or Subsidiary but only in that individual’s
position as an employee and not as a director. 
  
 ARTICLE 8

 RESTRICTED STOCK AWARDS 
  
 8.1. GRANT OF RESTRICTED STOCK. The Committee is authorized to make Awards of Restricted Stock to Participants in such amounts and subject to such terms
and conditions as may be selected by the Committee. All Awards of Restricted Stock shall be evidenced by a Restricted Stock Award Agreement. 
  
 8.2. ISSUANCE AND RESTRICTIONS. Restricted Stock shall be subject to such restrictions on transferability and other restrictions as the Committee may
impose (including, without limitation, limitations on the right to vote Restricted Stock or the right to receive dividends on the Restricted Stock). These restrictions may lapse separately or in combination at such times, under such circumstances,
in such installments, upon the satisfaction of performance goals or otherwise, as the Committee determines at the time of the grant of the Award or thereafter. 
  

8.3. FORFEITURE. Except as otherwise determined by the Committee at the time of the grant of the Award or thereafter, upon termination of employment
during the applicable restriction period or upon failure to satisfy a performance goal during the applicable restriction period, Restricted Stock that is at that time subject to restrictions 

  

 - 10 - 

 
shall be forfeited and reacquired by Medco; provided, however, that the Committee may provide in any Award Agreement or summary that restrictions or
forfeiture conditions relating to Restricted Stock will be waived in whole or in part in the event of terminations resulting from specified causes, and the Committee may in other cases waive in whole or in part restrictions or forfeiture conditions
relating to Restricted Stock. 
  
 8.4. CERTIFICATES FOR RESTRICTED
STOCK. Restricted Stock granted under the Plan may be evidenced in such manner as the Committee shall determine. If certificates representing shares of Restricted Stock are registered in the name of the Participant, certificates must bear an
appropriate legend referring to the terms, conditions, and restrictions applicable to such Restricted Stock. 
  
 ARTICLE 9 
 PROVISIONS APPLICABLE TO AWARDS 
  
 9.1. STAND-ALONE, TANDEM, AND SUBSTITUTE AWARDS. Awards granted under the
Plan may, in the discretion of the Committee, be granted either alone or in addition to, in tandem with, or in substitution for, any other Award granted under the Plan. If an Award is granted in substitution for another Award, the Committee may
require the surrender of such other Award in consideration of the grant of the new Award. Awards granted in addition to or in tandem with other Awards may be granted either at the same time as or at a different time from the grant of such other
Awards. 
  
 9.2. TERM OF AWARD. The term of each Award shall be
for the period as determined by the Committee, provided that in no event shall the term of any Incentive Stock Option exceed a period of ten years from the date of its grant (or, if Section 7.2(e) applies, five years from the date of its grant).

  
 9.3. FORM OF PAYMENT FOR AWARDS. Subject to the terms of the
Plan and any applicable law or Award Agreement, payments or transfers to be made by the Corporation or a Parent or Subsidiary on the grant or exercise of an Award may be made in such form as the Committee determines at or after the time of grant,
including without limitation, cash, Stock, other Awards, or other property, or any combination, and may be made in a single payment or transfer, in installments, or on a deferred basis, in each case determined in accordance with rules adopted by,
and at the discretion of, the Committee. 
  
 9.4. LIMITS ON
TRANSFER. No right or interest of a Participant in any unexercised or restricted Award may be pledged, encumbered, or hypothecated to or in favor of any party other than the Corporation or a Parent or Subsidiary, or shall be subject to any lien,
obligation, or liability of such Participant to any other party other than the Corporation or a Parent or Subsidiary. No unexercised or restricted Award shall be assignable or transferable by a Participant other than by will or the laws of descent
and distribution or, except in the case of an Incentive Stock Option and only to the extent specifically authorized by the Committee, pursuant to a domestic relations order that would satisfy Section 414(p)(1)(A) of the Code if such Section applied
to an Award under the Plan; provided, however, that the Committee may (but need not) permit other 

  

 - 11 - 

 
transfers where the Committee concludes that such transferability (i) does not result in accelerated taxation, (ii) does not cause any Option intended to be
an Incentive Stock Option to fail to be described in Code Section 422(b), and (iii) is otherwise appropriate and desirable, taking into account any factors deemed relevant, including without limitation, any state or federal tax or securities laws or
regulations applicable to transferable Awards. Nothing in this Section 9.4 shall obligate the Committee to allow transfers pursuant to a domestic relations order. 
  
 9.5. BENEFICIARIES. Notwithstanding Section 9.4, a Participant may, in the manner and to the extent determined by the
Committee, designate a beneficiary to exercise the rights of the Participant and to receive any distribution with respect to any Award upon the Participant’s death. A beneficiary, legal guardian, legal representative, or other person claiming
any rights under the Plan is subject to all terms and conditions of the Plan and any Award Agreement applicable to the Participant, except to the extent the Plan and Award Agreement otherwise provide, and to any additional restrictions deemed
necessary or appropriate by the Committee. If no beneficiary has been designated or survives the Participant, payment shall be made to the Participant’s estate. Subject to the foregoing, a beneficiary designation may be changed or revoked by a
Participant at any time provided the change or revocation is filed with the Committee. Nothing in this Section 9.5 shall obligate the Committee to allow beneficiary designations. 
  
 9.6. STOCK CERTIFICATES. All Stock issuable under the Plan is subject to any stop-transfer orders and other restrictions as
the Committee deems necessary or advisable to comply with federal or state securities laws, rules and regulations and the rules of any national securities exchange or automated quotation system on which the Stock is listed, quoted, or traded. The
Committee may place legends on any Stock certificate to reference restrictions applicable to the Stock. 
  
 9.7. ACCELERATION UPON DEATH, RETIREMENT OR DISABILITY. Except as otherwise provided in an Award Agreement, summary of terms or Rules and Regulations
adopted by the Committee, upon the Participant’s death, Retirement or Disability during his employment or service as a consultant or director, all outstanding Options shall become fully exercisable and all restrictions on outstanding Restricted
Stock Awards shall lapse. Any Option shall thereafter continue or lapse in accordance with the other provisions of the Plan and the Award Agreement. To the extent that this provision causes Incentive Stock Options to exceed the dollar limitation set
forth in Section 7.2(d), the excess Options shall be deemed to be Non-Qualified Stock Options. 
  
 9.8. ACCELERATION UPON A CHANGE IN CONTROL. Except as otherwise provided in an Award Agreement, summary of terms or Rules and Regulations adopted by the Committee, upon the occurrence of a Change in Control, all
outstanding Options shall become fully exercisable and all restrictions on outstanding Awards shall lapse. To the extent that this provision causes Incentive Stock Options to exceed the dollar limitation set forth in Section 7.2(d), the excess
Options shall be deemed to be Non-Qualified Stock Options. 
  

 - 12 - 

 9.9. ACCELERATION FOR ANY OTHER REASON. Regardless of whether an event has occurred as described in
Section 9.7 or 9.8 above, the Committee may in its sole discretion at any time determine that all or a portion of a Participant’s Options shall become fully or partially exercisable, and/or that all or a part of the restrictions on all or a
portion of the outstanding Restricted Stock Awards shall lapse, in each case, as of such date as the Committee may, in its sole discretion, declare. The Committee may discriminate among Participants and among Awards granted to a Participant in
exercising its discretion pursuant to this Section 9.10. 
  
 9.10.
EFFECT OF ACCELERATION. If an Award is accelerated under Section 9.8 or 9.9, the Committee may, in its sole discretion, provide (i) that the Award will expire after a designated period of time after such acceleration to the extent not then
exercised, (ii) that the Award will be settled in cash rather than Stock, (iii) that, if the Award will be assumed by another party to a transaction giving rise to the acceleration or otherwise be equitably converted or substituted in connection
with such transaction, (iv) that the Award may be settled by payment in cash or cash equivalents equal to the excess of the Fair Market Value of the underlying Stock, as of a specified date associated with the transaction, over the exercise price of
the Award, or (v) any combination of the foregoing. The Committee’s determination need not be uniform and may be different for different Participants whether or not such Participants are similarly situated. 
  
 9.11. PERFORMANCE GOALS. The Committee may determine that any Award granted
pursuant to this Plan to a Participant (including, but not limited to, Participants who are Covered Employees) shall be determined solely on the basis of (a) the achievement by the Corporation or a Parent or Subsidiary of a specified target return,
or target growth in return, on equity or assets, (b) the achievement by the Corporation or a Parent or Subsidiary of a specified target total stockholder return (stock price appreciation plus reinvested dividends), or target growth in total
stockholder return, (c) the Corporation’s, Parent’s or Subsidiary’s stock price, (d) the achievement by an individual or a business unit of the Corporation, Parent or Subsidiary of a specified target, or target growth in, revenues,
net income or earnings per share, or (e) any combination of the goals set forth in (a) through (d) above. If an Award is made on such basis, the Committee shall establish goals prior to the beginning of the period for which such performance goal
relates (or such later date as may be permitted under Code Section 162(m) or the regulations thereunder) and the Committee has the right for any reason to reduce (but not increase) any Award, notwithstanding the achievement of a specified goal. Any
payment of an Award granted with performance goals shall be conditioned on the written certification of the Committee in each case that the performance goals and any other material conditions were satisfied. 
  
 9.14. TERMINATION OF EMPLOYMENT. Whether military, government or other
service or other leave of absence shall constitute a termination of employment shall be determined in each case by the Committee at its discretion, and any determination by the Committee shall be final and conclusive. A termination of employment
shall not occur (i) in a circumstance in which a Participant transfers from the Corporation to one of its Parents or Subsidiaries, transfers from a Parent or Subsidiary to the Corporation, or 

  

 - 13 - 

 
transfers from one Parent or Subsidiary to another Parent or Subsidiary, or (ii) in the discretion of the Committee as specified at or prior to such
occurrence, in the case of a spin-off, sale, or disposition of the Participant’s employer from the Corporation or any Parent or Subsidiary. To the extent that this provision causes Incentive Stock Options to extend beyond three months from the
date a Participant is deemed to be an employee of the Corporation, a Parent or Subsidiary for purposes of Section 424(f) of the Code, the Options held by such Participant shall be deemed to be Non-Qualified Stock Options. 
  
 ARTICLE 10 
 CHANGES IN CAPITAL STRUCTURE 
  
 10.1. GENERAL. In the event of a corporate transaction involving the Corporation (including, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger,
consolidation, split-up, spin-off, combination or exchange of shares), the authorization limits under Section 5.1 and 5.4 shall be adjusted proportionately, and the Committee may adjust Awards to preserve the benefits or potential benefits of the
Awards. Action by the Committee may include: (i) adjustment of the number and kind of shares which may be delivered under the Plan; (ii) adjustment of the number and kind of shares subject to outstanding Awards; (iii) adjustment of the exercise
price of outstanding Awards; and (iv) any other adjustments that the Committee determines to be equitable. In addition, the Committee may, in its sole discretion, provide (i) that Awards will be settled in cash rather than Stock, (ii) that Awards
will become immediately vested and exercisable and will expire after a designated period of time to the extent not then exercised, (iii) that Awards will be assumed by another party to a transaction or otherwise be equitably converted or substituted
in connection with such transaction, (iv) that outstanding Awards may be settled by payment in cash or cash equivalents equal to the excess of the Fair Market Value of the underlying Stock, as of a specified date associated with the transaction,
over the exercise price of the Award, or (v) any combination of the foregoing. The Committee’s determination need not be uniform and may be different for different Participants whether or not such Participants are similarly situated. Without
limiting the foregoing, in the event a stock dividend or stock split is declared upon the Stock, the authorization limits under Section 5.1 and 5.4 shall be increased proportionately, and the shares of Stock then subject to each Award shall be
increased proportionately without any change in the aggregate purchase price therefor. 
  
 ARTICLE 11 
 AMENDMENT, MODIFICATION AND TERMINATION 
  
 11.1. AMENDMENT, MODIFICATION AND TERMINATION. Subject to Section 11.2, the
Board or the Committee may, at any time and from time to time, amend, modify or terminate the Plan without stockholder approval; provided, however, that the Board or Committee may condition any amendment or modification on the approval of
stockholders of the Corporation if such approval is necessary or deemed advisable with respect to tax, securities, or other applicable laws, policies, or regulations; and provided further that the last sentence of Section 11.2 may not be amended or
modified without stockholder approval. 
  

 - 14 - 

 11.2. AWARDS PREVIOUSLY GRANTED. No termination, amendment, or modification of the Plan shall adversely
affect any Award previously granted under the Plan, without the written consent of the Participant. At any time and from time to time, the Committee may amend, modify or terminate any outstanding Award without approval of the Participant; provided,
however, that: 
  
 (a) subject to the terms of
the applicable Award Agreement, such amendment, modification, or termination shall not, without the Participant’s consent, reduce or diminish the value of such Award determined as if the Award had been exercised, vested, cashed in or otherwise
settled on the date of such amendment or termination; 
  
 (b) the original term of any Option may not be extended without the prior approval of the stockholders of Medco; and 
  
 (c) except as otherwise provided in Article 10, the exercise price of any Option may not be reduced, directly or indirectly, without the
prior approval of the stockholders of Medco. 
  
 ARTICLE 12

 GENERAL PROVISIONS 
  
 12.1. NO RIGHTS TO AWARDS. No Participant or any eligible participant shall have any claim to be granted any Award under the Plan, and neither the
Corporation, Medco nor the Committee is obligated to treat Participants or eligible participants uniformly. 
  
 12.2. NO STOCKHOLDER RIGHTS. No Award gives the Participant any of the rights of a stockholder of Medco unless and until shares of Stock are in fact
issued to such person in connection with such Award. 
  
 12.3.
WITHHOLDING. The Corporation or any Parent or Subsidiary shall have the authority and the right to deduct or withhold, or require a Participant to remit to the Corporation, an amount sufficient to satisfy federal, state, and local taxes (including
the Participant’s FICA obligation) required by law to be withheld with respect to any taxable event arising as a result of the Plan. With respect to withholding required upon any taxable event under the Plan, the Committee may, at the time the
Award is granted or thereafter, require or permit that any such withholding requirement be satisfied, in whole or in part, by withholding from the Award shares of Stock having a Fair Market Value on the date of withholding equal to the minimum
amount (and not any greater amount) required to be withheld for tax purposes, all in accordance with such procedures as the Committee establishes. 
  

 - 15 - 

 12.4. NO RIGHT TO CONTINUED SERVICE. Nothing in the Plan or any Award Agreement shall interfere with or
limit in any way the right of the Corporation or any Parent or Subsidiary to terminate any Participant’s employment or status as an officer, director or consultant at any time, nor confer upon any Participant any right to continue as an
employee, officer, director or consultant of the Corporation or any Parent or Subsidiary. 
  
 12.5. UNFUNDED STATUS OF AWARDS. The Plan is intended to be an “unfunded” plan for incentive and deferred compensation. With respect to any payments not yet made to a Participant pursuant to an Award,
nothing contained in the Plan or any Award Agreement shall give the Participant any rights that are greater than those of a general creditor of the Corporation or any Parent or Subsidiary. 
  
 12.6. INDEMNIFICATION. To the extent allowable under applicable law, each
member of the Committee shall be indemnified and held harmless by Medco from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by such member in connection with or resulting from any claim, action, suit, or
proceeding to which such member may be a party or in which he may be involved by reason of any action or failure to act under the Plan and against and from any and all amounts paid by such member in satisfaction of judgment in such action, suit, or
proceeding against him provided he gives Medco an opportunity, at its own expense, to handle and defend the same before he undertakes to handle and defend it on his own behalf. The foregoing right of indemnification shall not be exclusive of any
other rights of indemnification to which such persons may be entitled under Medco’s Certificate of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that Medco may have to indemnify them or hold them harmless. 

 
 12.7. RELATIONSHIP TO OTHER BENEFITS. No payment under the Plan shall be
taken into account in determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or benefit plan of the Corporation or any Parent or Subsidiary unless provided otherwise in such other plan. 

 
 12.8. EXPENSES. The expenses of administering the Plan shall be borne by
the Corporation and its Parents or Subsidiaries. 
  
 12.9. TITLES
AND HEADINGS. The titles and headings of the Sections in the Plan are for convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control. 
  
 12.10. GENDER AND NUMBER. Except where otherwise indicated by the context,
any masculine term used herein also shall include the feminine; the plural shall include the singular and the singular shall include the plural. 
  
 12.11. FRACTIONAL SHARES. No fractional shares of Stock shall be issued and the Committee shall determine, in its discretion, whether cash shall be given
in lieu of fractional shares or whether such fractional shares shall be eliminated by rounding up. 
  

 - 16 - 

 12.12. GOVERNMENT AND OTHER REGULATIONS. The obligation of Medco to make payment of awards in Stock or
otherwise shall be subject to all applicable laws, rules, and regulations, and to such approvals by government agencies as may be required. Medco shall be under no obligation to register under the 1933 Act, or any state securities act, any of the
shares of Stock issued in connection with the Plan. The shares issued in connection with the Plan may in certain circumstances be exempt from registration under the 1933 Act, and the Corporation may restrict the transfer of such shares in such
manner as it deems advisable to ensure the availability of any such exemption. 
  
 12.13. GOVERNING LAW. To the extent not governed by federal law, the Plan and all Award Agreements shall be construed in accordance with and governed by the laws of the State of Tennessee. 
  
 12.14. ADDITIONAL PROVISIONS. Each Award Agreement may contain such other
terms and conditions as the Committee may determine; provided that such other terms and conditions are not inconsistent with the provisions of this Plan.
