2. System, Transaction, and Additional Items Reviews. As set forth more fully in Appendix B, the IRO Reviews shall consist of two components: Systems Reviews and Transactions Reviews. The Systems Reviews shall assess United Therapeutics’ systems, processes, policies, and procedures relating to the Contribution and Assistance Related Functions. If there are no material changes in United Therapeutics’ relevant systems, processes, policies, and procedures, the Systems Reviews shall be performed for the first and fourth Reporting Periods. If United Therapeutics materially changes its relevant systems, processes, policies, and procedures, the IRO shall

perform a Systems Review for the Reporting Period in which such changes were made in addition to conducting the Systems Review for the first and fourth Reporting Periods, as set forth more fully in Appendix B.

The Transactions Reviews shall be performed annually and shall cover each of the five Reporting Periods. The Transactions Reviews shall assess Contribution and Assistance Related Functions and may assess Promotional Functions. The IRO(s) shall perform all components of each annual Transaction Review. As set forth more fully in Appendix B, the Transactions Review shall include several components.

In addition, as set forth in Appendix B, as part of the Transactions Reviews, OIG may at its discretion require a review of up to three additional areas or practices of United Therapeutics identified by OIG in its discretion (hereafter “Additional Items”). For purposes of identifying the Additional Items to be included in the Transactions Review for a particular Reporting Period, OIG will consult with United Therapeutics and may consider internal audit and monitoring work conducted by United Therapeutics, the Government Reimbursed Product portfolio, the nature and scope of United Therapeutics’ promotional practices and arrangements with HCPs and HCIs, and other information known to it.

As set forth more fully in Appendix B, United Therapeutics may propose to OIG that its internal audit(s) be partially substituted for one or more of the Additional Items that would otherwise be reviewed by the IRO as part of the Transactions Review. OIG retains sole discretion over whether, and in what manner, to allow United Therapeutics’ internal audit and monitoring work to be substituted for any portion of the Additional Items review conducted by the IRO.

OIG shall notify United Therapeutics of the nature and scope of the IRO review for each of the Additional Items not later than 120 days prior to the end of each Reporting Period. Prior to undertaking the review of the Additional Items, the IRO and/or United Therapeutics shall submit an audit work plan to OIG for approval and the IRO shall conduct the review of the Additional Items based on a work plan approved by OIG.

3. IRO Review Reports. The IRO shall prepare a report based upon each IRO Review performed (IRO Review Report). Information to be included in the IRO Review Report is described in Appendix A and Appendix B.

4. Independence and Objectivity Certification. The IRO shall include in its report(s) to United Therapeutics a certification that the IRO has: (a) evaluated its professional independence and objectivity with respect to the reviews required under this Section III.E; and (b) concluded that it is, in fact, independent and objective in accordance with the requirements specified in Appendix A. The IRO’s certification shall include a summary of current and prior engagements between United Therapeutics and IRO.

F. Disclosure Program.

Within 90 days after the Effective Date, United Therapeutics shall establish a Disclosure Program that includes a mechanism (e.g., a toll free compliance telephone line) to enable individuals to disclose, to the Compliance Officer or some other person who is not in the disclosing individual’s chain of command, any identified issues or questions associated with United Therapeutics’ policies, conduct, practices, or procedures with respect to a Federal health care program believed by the individual to be a potential violation of criminal, civil, or administrative law. United Therapeutics shall appropriately publicize the existence of the Disclosure Program and the disclosure mechanism (e.g., via periodic e-mails to employees, or by posting the information in prominent common areas).

The Disclosure Program shall emphasize a nonretribution, nonretaliation policy and shall include a reporting mechanism for anonymous communications for which appropriate confidentiality shall be maintained. The Disclosure Program also shall include a requirement that all of United Therapeutics’ Covered Persons shall be expected to report suspected violations of any Federal health care program requirements to the Compliance Officer or other appropriate individual designated by United Therapeutics. Upon receipt of a disclosure, the Compliance Officer (or designee) shall gather all relevant information from the disclosing individual. The Compliance Officer (or designee) shall make a preliminary, good faith inquiry into the allegations set forth in every disclosure to ensure that it obtains all necessary information to determine whether a further review should be conducted. For any disclosure that is sufficiently specific so that it reasonably: (1) permits a determination of the appropriateness of the alleged improper practice; and (2) provides an opportunity for taking corrective action, United Therapeutics shall conduct an internal review of the allegations set forth in the disclosure and ensure that proper follow-up is conducted.

The Compliance Officer (or designee) shall maintain a disclosure log and shall record each disclosure in the disclosure log within two business days of receipt of the disclosure. The disclosure log shall include a summary of each disclosure received (whether anonymous or not), the status of the respective internal reviews, and any corrective action taken in response to the internal reviews.

G. Ineligible Persons.

4. Pending Charges and Proposed Exclusions. If United Therapeutics has actual notice that a Covered Person is charged with a criminal offense that falls within the scope of 42 U.S.C. §§ 1320a-7(a), 1320a-7(b)(1)-(3), or is proposed for exclusion during the Covered Person’s employment or contract term, United Therapeutics shall take all appropriate actions to ensure that the responsibilities of that Covered Person have not and shall not adversely affect the quality of care rendered to any beneficiary, or the accuracy of any claims submitted to any Federal health care program.

For purposes of this CIA, the “commercial organization” shall be defined to include the sales, marketing, and similar commercial business units of United Therapeutics. United Therapeutics’ commercial organization shall have no involvement in, or influence over, the review, approval, or implementation of any budget or other decisions or activities relating to donations to Independent Charity PAPs.

United Therapeutics shall approve the annual budget for donations to Independent Charity PAPs at a level within the organization above the commercial organization (e.g.,

at the executive level). After the annual budget is approved, the Independent Charity Interaction Team shall have sole responsibility for allocating the approved budget across donations to Independent Charity PAPs and to any disease state fund established by the Independent Charity PAP.

The Independent Charity Interaction Team shall have sole responsibility for assessing requests for additional or supplemental funding from Independent Charity PAPs outside of the annual budget. Such requests shall be assessed against standardized, objective criteria established by the Independent Charity Interaction Team. United Therapeutics legal and compliance personnel shall also be involved in the review and approval of requests for additional/supplemental funding. The purpose of this review shall be to ensure that any supplemental funding to the Independent Charity PAP is provided in accordance with applicable Federal health care program requirements, OIG guidance, and United Therapeutics Policies and Procedures.

3. Criteria Relating to Donations to Independent Charity PAPs. Within 90 days after the Effective Date, the Independent Charity Interaction Team (with input from the legal department and compliance departments) shall establish standardized, objective written criteria that govern donations to Independent Charity PAPs and any specific disease state funds of such PAPs. The criteria shall be designed to ensure that the Independent Charity PAP does not function as a conduit for payments or other benefits from United Therapeutics to patients and does not impermissibly influence patients’ drug choices.

United Therapeutics’ Independent Charity Interaction Team shall gather information about Independent Charity PAPs and their disease funds in a manner that does not exert or attempt to exert any direct or indirect control over the entity operating the PAP or over its assistance program. United Therapeutics shall not influence or attempt to influence, directly or indirectly, the identification, delineation, establishment, or modification of, or the parameters relating to, any disease fund by the Independent Charity PAP.

Personnel from United Therapeutics’ legal and compliance departments shall review all proposed donations and arrangements between United Therapeutics and any Independent Charity PAP. United Therapeutics shall not make donations to any Independent Charity Group or to any disease state fund of an Independent Charity PAP until after the legal and compliance review has occurred.

United Therapeutics agrees that it will donate to an Independent Charity PAP only if the following criteria are satisfied:

United Therapeutics does not and shall not exert (directly or through any affiliate) any influence or control over the identification, delineation, establishment, or modification of any specific disease funds operated by the Independent Charity PAP. Among other things, United Therapeutics has not made and shall not make (directly or through any affiliate) suggestions or requests to the Independent Charity PAP about the identification, delineation, establishment, or modification of disease state funds;

b. United Therapeutics does not and shall not exert (directly or through any affiliate) any direct or indirect influence or control over the Independent Charity PAP’s process or criteria for determining eligibility of patients who qualify for its assistance program;

c.

d. United Therapeutics does not and shall not provide donations for a disease state fund that covers only a single product or that covers only United Therapeutics’ products.

United Therapeutics shall continue the Independent Charity PAP processes described above (or equivalent processes) throughout the term of the CIA, and shall notify OIG in writing at least 60 days prior to the implementation of any modifications to the process described above.

With respect to such releases, United Therapeutics shall have the rights set forth at 45

C.F.R. § 5.65(d).

X. BREACH AND DEFAULT PROVISIONS

United Therapeutics is expected to fully and timely comply with all of its CIA obligations.

A. Stipulated Penalties for Failure to Comply with Certain Obligations. As a contractual remedy, United Therapeutics and OIG hereby agree that failure to comply with certain obligations as set forth in this CIA may lead to the imposition of the following monetary penalties (hereinafter referred to as “Stipulated Penalties”) in accordance with the following provisions.

1. A Stipulated Penalty of $2,500 (which shall begin to accrue on the day after the date the obligation became due) for each day United Therapeutics fails to establish, implement or comply with any of the following obligations as described in Section III:

a. a Compliance Officer;

b. a Compliance Committee;

c. the Board of Directors compliance obligations and the engagement of a Compliance Expert, the performance of a Compliance Program Review and the preparation of a Compliance Program Review Report;

d. the management certification obligations;

e. written Policies and Procedures;

f. training and education of Covered Persons and Board Members;

g. a risk assessment and internal review process;

h. a Disclosure Program;

i. Ineligible Persons screening and removal requirements;

j. notification of Government investigations or legal proceedings;

k. reporting of Reportable Events; and

l. the Independent Charity PAP processes, policies, and procedures required by Section III.J.

2. A Stipulated Penalty of $2,500 (which shall begin to accrue on the day after the date the obligation became due) for each day United Therapeutics fails to engage and use an IRO as required by Section III.E, Appendix A, or Appendix B.

3. A Stipulated Penalty of $2,500 (which shall begin to accrue on the day after the date the obligation became due) for each day United Therapeutics fails to submit a complete Implementation Report, Annual Report or any certification to OIG in accordance with the requirements of Section V by the deadlines for submission.

4. A Stipulated Penalty of $2,500 (which shall begin to accrue on the day after the date the obligation became due) for each day United Therapeutics fails to submit any IRO Review report in accordance with the requirements of Section III.E and Appendix B.

5. A Stipulated Penalty of $1,500 for each day United Therapeutics fails to grant access as required in Section VII. (This Stipulated Penalty shall begin to accrue on the date United Therapeutics fails to grant access.)

6. A Stipulated Penalty of $50,000 for each false certification submitted by or on behalf of United Therapeutics as part of its Implementation Report, any Annual Report, additional documentation to a report (as requested by OIG), or otherwise required by this CIA.

7. A Stipulated Penalty of $1,000 for each day United Therapeutics fails to comply fully and adequately with any obligation of this CIA. OIG shall provide notice to United Therapeutics stating the specific grounds for its determination that United Therapeutics has failed to comply fully and adequately with the CIA obligation(s) at issue and steps United Therapeutics shall take to comply with the CIA. (This

Stipulated Penalty shall begin to accrue 10 days after the date United Therapeutics receives this notice from OIG of the failure to comply.) A Stipulated Penalty as described in this Subsection shall not be demanded for any violation for which OIG has sought a Stipulated Penalty under Subsections 1- 6 of this Section.

B. Timely Written Requests for Extensions. United Therapeutics may, in advance of the due date, submit a timely written request for an extension of time to perform any act or file any notification or report required by this CIA. Notwithstanding any other provision in this Section, if OIG grants the timely written request with respect to an act, notification, or report, Stipulated Penalties for failure to perform the act or file the notification or report shall not begin to accrue until one day after United Therapeutics fails to meet the revised deadline set by OIG. Notwithstanding any other provision in this Section, if OIG denies such a timely written request, Stipulated Penalties for failure to perform the act or file the notification or report shall not begin to accrue until three days after United Therapeutics receives OIG’s written denial of such request or the original due date, whichever is later. A “timely written request” is defined as a request in writing received by OIG at least five days prior to the date by which any act is due to be performed or any notification or report is due to be filed.

C. Payment of Stipulated Penalties.

1. Demand Letter. Upon a finding that United Therapeutics has failed to comply with any of the obligations described in Section X.A and after determining that Stipulated Penalties are appropriate, OIG shall notify United Therapeutics of: (a) United Therapeutics’ failure to comply; and (b) OIG’s exercise of its contractual right to demand payment of the Stipulated Penalties (this notification is referred to as the “Demand Letter”).

2. Response to Demand Letter. Within 10 days after the receipt of the Demand Letter, United Therapeutics shall either: (a) cure the breach to OIG’s satisfaction and pay the applicable Stipulated Penalties or (b) request a hearing before an HHS administrative law judge (ALJ) to dispute OIG’s determination of noncompliance, pursuant to the agreed upon provisions set forth below in Section X.E. In the event United Therapeutics elects to request an ALJ hearing, the Stipulated Penalties shall continue to accrue until United Therapeutics cures, to OIG’s satisfaction, the alleged breach in dispute. Failure to respond to the Demand Letter in one of these two manners within the allowed time period shall be considered a material breach of this CIA and shall be grounds for exclusion under Section X.D.

3. Form of Payment. Payment of the Stipulated Penalties shall be made by electronic funds transfer to an account specified by OIG in the Demand Letter.

4. Independence from Material Breach Determination. Except as set forth in Section X.D.1.d, these provisions for payment of Stipulated Penalties shall not affect or otherwise set a standard for OIG’s decision that United Therapeutics has materially breached this CIA, which decision shall be made at OIG’s discretion and shall be governed by the provisions in Section X.D, below.

D. Exclusion for Material Breach of this CIA.

1. Definition of Material Breach. A material breach of this CIA means:

a. repeated violations or a flagrant violation of any of the obligations under this CIA, including, but not limited to, the obligations addressed in Section X.A;

b. a failure by United Therapeutics to report a Reportable Event and take corrective action as required in Section III.I;

c. a failure to engage and use an IRO in accordance with Section III.E, Appendix A, or Appendix B; or

d. a failure to respond to a Demand Letter concerning the payment of Stipulated Penalties in accordance with Section X.C.

2. Notice of Material Breach and Intent to Exclude. The parties agree that a material breach of this CIA by United Therapeutics constitutes an independent basis for United Therapeutics’ exclusion from participation in the Federal health care programs. The length of the exclusion shall be in OIG’s discretion, but not more than five years per material breach. Upon a determination by OIG that United Therapeutics has materially breached this CIA and that exclusion is the appropriate remedy, OIG shall notify United Therapeutics of: (a) United Therapeutics’ material breach; and (b) OIG’s intent to exercise its contractual right to impose exclusion (this notification is hereinafter referred to as the “Notice of Material Breach and Intent to Exclude”).

3. Opportunity to Cure. United Therapeutics shall have 30 days from the date of receipt of the Notice of Material Breach and Intent to Exclude to demonstrate to OIG’s satisfaction that:

a. the alleged material breach has been cured; or

b. the alleged material breach cannot be cured within the 30 day period, but that: (i) United Therapeutics has begun to take action to cure the material breach; (ii) United Therapeutics is pursuing such action with due diligence; and (iii) United Therapeutics has provided to OIG a reasonable timetable for curing the material breach.

4. Exclusion Letter. If, at the conclusion of the 30 day period, United Therapeutics fails to satisfy the requirements of Section X.D.3, OIG may exclude United Therapeutics from participation in the Federal health care programs. OIG shall notify United Therapeutics in writing of its determination to exclude United Therapeutics (this letter shall be referred to hereinafter as the “Exclusion Letter”). Subject to the Dispute Resolution provisions in Section X.E, below, the exclusion shall go into effect 30 days after the date of United Therapeutics’ receipt of the Exclusion Letter. The exclusion shall have national effect. Reinstatement to program participation is not automatic. At the end of the period of exclusion, United Therapeutics may apply for reinstatement by submitting a written request for reinstatement in accordance with the provisions at 42 C.F.R. §§ 1001.3001-.3004.

E. Dispute Resolution

1. Review Rights. Upon OIG’s delivery to United Therapeutics of its Demand Letter or of its Exclusion Letter, and as an agreed-upon contractual remedy for the resolution of disputes arising under this CIA, United Therapeutics shall be afforded certain review rights comparable to the ones that are provided in 42 U.S.C. § 1320a-7(f) and 42 C.F.R. Part 1005 as if they applied to the Stipulated Penalties or exclusion sought pursuant to this CIA. Specifically, OIG’s determination to demand payment of Stipulated Penalties or to seek exclusion shall be subject to review by an HHS ALJ and, in the event of an appeal, the HHS Departmental Appeals Board (DAB), in a manner consistent with the provisions in 42 C.F.R. § 1005.2-1005.21. Notwithstanding the language in 42 C.F.R. § 1005.2(c), the request for a hearing involving Stipulated Penalties shall be made within 10 days after receipt of the Demand Letter and the request for a hearing involving

exclusion shall be made within 25 days after receipt of the Exclusion Letter. The procedures relating to the filing of a request for a hearing can be found at http://www.hhs.gov/dab/divisions/civil/procedures/divisionprocedures.html.

2. Stipulated Penalties Review. Notwithstanding any provision of Title 42 of the United States Code or Title 42 of the Code of Federal Regulations, the only issues in a proceeding for Stipulated Penalties under this CIA shall be: (a) whether United Therapeutics was in full and timely compliance with the obligations of this CIA for which OIG demands payment; and (b) the period of noncompliance. United Therapeutics shall have the burden of proving its full and timely compliance and the steps taken to cure the noncompliance, if any. OIG shall not have the right to appeal to the DAB an adverse ALJ decision related to Stipulated Penalties. If the ALJ agrees with OIG with regard to a finding of a breach of this CIA and orders United Therapeutics to pay Stipulated Penalties, such Stipulated Penalties shall become due and payable 20 days after the ALJ issues such a decision unless United Therapeutics requests review of the ALJ decision by the DAB. If the ALJ decision is properly appealed to the DAB and the DAB upholds the determination of OIG, the Stipulated Penalties shall become due and payable 20 days after the DAB issues its decision.

3. Exclusion Review. Notwithstanding any provision of Title 42 of the United States Code or Title 42 of the Code of Federal Regulations, the only issues in a proceeding for exclusion based on a material breach of this CIA shall be whether United Therapeutics was in material breach of this CIA and, if so, whether:

a. United Therapeutics cured such breach within 30 days of its receipt of the Notice of Material Breach; or

b. the alleged material breach could not have been cured within the 30 day period, but that, during the 30 day period following United Therapeutics’ receipt of the Notice of Material Breach: (i) United Therapeutics had begun to take action to cure the material breach within that period; (ii) United Therapeutics pursued such action with due diligence; and (iii) United Therapeutics provided to OIG within that period a reasonable timetable for curing the material breach.

For purposes of the exclusion herein, exclusion shall take effect only after an ALJ decision favorable to OIG, or, if the ALJ rules for United Therapeutics, only after a DAB

decision in favor of OIG. United Therapeutics’ election of its contractual right to appeal to the DAB shall not abrogate OIG’s authority to exclude United Therapeutics upon the issuance of an ALJ’s decision in favor of OIG. If the ALJ sustains the determination of OIG and determines that exclusion is authorized, such exclusion shall take effect 20 days after the ALJ issues such a decision, notwithstanding that United Therapeutics may request review of the ALJ decision by the DAB. If the DAB finds in favor of OIG after an ALJ decision adverse to OIG, the exclusion shall take effect 20 days after the DAB decision. United Therapeutics shall waive its right to any notice of such an exclusion if a decision upholding the exclusion is rendered by the ALJ or DAB. If the DAB finds in favor of United Therapeutics, United Therapeutics shall be reinstated effective on the date of the original exclusion.

4. Finality of Decision. The review by an ALJ or DAB provided for above shall not be considered to be an appeal right arising under any statutes or regulations. Consequently, the parties to this CIA agree that the DAB’s decision (or the ALJ’s decision if not appealed) shall be considered final for all purposes under this CIA.

XI. EFFECTIVE AND BINDING AGREEMENT

United Therapeutics and OIG agree as follows:

A. This CIA shall become final and binding on the date the final signature is obtained on the CIA.

B. This CIA constitutes the complete agreement between the parties and may not be amended except by written consent of the parties to this CIA.

C. All requirements and remedies set forth in this CIA are in addition to and do not affect (1) United Therapeutics’ responsibility to follow all applicable Federal health care program requirements or (2) the government’s right to impose appropriate remedies for failure to follow applicable Federal health care program requirements.

D. The undersigned United Therapeutics signatories represent and warrant that they are authorized to execute this CIA. The undersigned OIG signatories represent that they are signing this CIA in their official capacity and that they are authorized to execute this CIA.

A. IRO Engagement

1. United Therapeutics shall engage an IRO that possesses the qualifications set forth in Paragraph B, below, to perform the responsibilities in Paragraph C, below. The IRO shall conduct the review in a professionally independent and objective fashion, as set forth in Paragraph D. Within 30 days after OIG receives the information identified in Section V.A.9 of the CIA or any additional information submitted by United Therapeutics in response to a request by OIG, whichever is later, OIG will notify United Therapeutics if the IRO is unacceptable. Absent notification from OIG that the IRO is unacceptable, United Therapeutics may continue to engage the IRO.

2. If United Therapeutics engages a new IRO during the term of the CIA, that IRO must also meet the requirements of this Appendix. If a new IRO is engaged, United Therapeutics shall submit the information identified in Section V.A.9 of the CIA to OIG within 30 days of engagement of the IRO. Within 30 days after OIG receives this information or any additional information submitted by United Therapeutics at the request of OIG, whichever is later, OIG will notify United Therapeutics if the IRO is unacceptable. Absent notification from OIG that the IRO is unacceptable, United Therapeutics may continue to engage the IRO.

B. IRO Qualifications

The IRO shall:

1. assign individuals to conduct the IRO Reviews who have expertise in the pharmaceutical industry and in Federal health care program requirements (including but not limited to, the Federal Anti-Kickback Statute and the False Claims Act) applicable to the reviews being conducted;

2. assign individuals to design and select samples for the Transactions Reviews who are knowledgeable about the appropriate statistical sampling techniques; and

3. have sufficient staff and resources to conduct the reviews required by the CIA on a timely basis.

C. IRO Responsibilities

The IRO shall:

1. perform each component of the IRO Review in accordance with the specific requirements of the CIA;

2. follow all applicable Federal health care program requirements in making assessments in the IRO Review;

E. IRO Removal/Termination

1. United Therapeutics and IRO. If United Therapeutics terminates its IRO or if the IRO withdraws from the engagement during the term of the CIA, United Therapeutics must submit a notice explaining (a) its reasons for termination of the IRO or (b) the IRO’s reasons for its withdrawal to OIG, no later than 30 days after termination or withdrawal. United Therapeutics must engage a new IRO in accordance with Paragraph A of this Appendix and within 60 days of termination or withdrawal of the IRO.

2. OIG Removal of IRO. In the event OIG has reason to believe the IRO does not possess the qualifications described in Paragraph B, is not independent and objective as set forth in Paragraph D, or has failed to carry out its responsibilities as described in Paragraph C, OIG shall notify United Therapeutics in writing regarding OIG’s basis for determining that the IRO has not met the requirements of this Appendix.

Appendix B

I. IRO Engagement, General Description

As specified more fully below, United Therapeutics shall retain an Independent Review Organization (IRO) to perform engagements to assist United Therapeutics in assessing and evaluating its systems, processes, policies, and procedures related to Contribution and Assistance Related Functions and, potentially, Promotional Functions, as defined in the CIA (IRO Reviews). The IRO Reviews shall consist of two components - a systems review (Systems Review) and a transactions review (Transactions Review) as described more fully below. United Therapeutics may engage, at its discretion, a single entity to perform both components of the IRO Reviews provided that the entity has the necessary expertise and capabilities to perform both.

If there are no material changes in United Therapeutics’ systems, processes, policies, and procedures relating to Contribution and Assistance Related Functions, the IRO shall perform the Systems Review for the first and fourth Reporting Periods. If United Therapeutics materially changes its systems, processes, policies, and procedures relating to Contribution and Assistance Related Functions, the IRO shall perform a Systems Review for the Reporting Period(s) in which such changes were made in addition to conducting the Review as set forth above. The additional Systems Review(s) shall consist of: 1) an identification of the material changes; 2) an assessment of whether other systems, processes, policies, and procedures previously reported did not materially change; and 3) a review of the systems, processes, policies, and procedures that materially changed. The IRO shall conduct the Transactions Review for each Reporting Period of the CIA.

II. IRO Systems Review

The Systems Review shall be a review of United Therapeutics’ systems, processes, policies, and procedures (including the controls on those systems, processes, policies, and procedures) relating to select Contribution and Assistance Related Functions. Where practical, United Therapeutics personnel may compile documentation, schedule and organize interviews, and undertake other efforts to assist the IRO in performing the Systems Review. The IRO is not required to undertake a de novo review of the information gathered or activities undertaken by United Therapeutics pursuant to the preceding sentence.

More specifically, the IRO shall review United Therapeutics’ systems, processes, policies, and procedures associated with the following (hereafter “Reviewed Policies and Procedures”):

1) United Therapeutics’ systems, policies, processes, and procedures relating to arrangements and interactions with (including donations to and sponsorship of) independent third-party patient assistance programs (Independent Charity PAPs).

This review shall include an assessment of the following:

a. United Therapeutics’ organizational structure as it relates to arrangements and interactions with Independent Charity PAPS, including:

i. the identification of those individuals, departments, or groups within United Therapeutics (e.g., the Compliance Officer, the Grants Committee, legal, compliance, medical affairs, executive level officers) that have responsibility for, or involvement with, such arrangements and interactions;

ii. the respective scope and nature of the responsibilities of each individual, department, or group with responsibility for, or involvement with, arrangements and interactions with Independent Charity PAPs;

iii. the identification of those individuals, departments, or groups within United Therapeutics (e.g., the commercial organization) that are precluded from involvement with arrangements and interactions with Independent Charity PAPs; and

iv. the manner by which the separation of Independent Charity PAP- related responsibilities from the commercial organization is enforced.

b. United Therapeutics’ written policies and procedures as they relate to arrangements and interactions with Independent Charity PAPs, including:

i. the criteria governing whether and under what circumstances United Therapeutics would donate to an Independent Charity PAP or any specific disease state fund of such a PAP;

10) Whether, based on its review, the IRO found that United Therapeutics exerted influence or control over the Independent Charity PAP in violation of United Therapeutics’ policies and procedures, including those outlined in Section III.J.3.

B. IRO Review of Additional Items

As set forth in Section III.E.2 of the CIA, for each Reporting Period, OIG at its discretion may identify up to three additional items for the IRO to review (hereafter “Additional Items”). The Additional Items may include activities undertaken by United Therapeutics in connection with Promotional Functions, as defined in Section II.C.3 of the CIA. For the second through fifth Reporting Periods, the Additional Items Review may include activities undertaken by United Therapeutics in connection with any Pharmaceutical Manufacturer PAP, including the provision of free product to patients.

No later than 150 days prior to the end of the applicable Reporting Period, OIG shall notify United Therapeutics of the nature and scope of the IRO review to be conducted for each of the Additional Items. Prior to undertaking the review of the Additional Items, the IRO and/or United Therapeutics shall submit an audit work plan to OIG for approval.

The IRO shall conduct the review of the Additional Items based on a work plan approved by OIG. The IRO shall include information about its review of each Additional Item in the Transactions Review Report (including a description of the review conducted for each Additional Item; the IRO’s findings based on its review for each Additional Item; and the IRO’s recommendations for any changes in United Therapeutics’ systems, processes, policies, and procedures based on its review of each Additional Item).

United Therapeutics may propose to OIG that relevant internal audit(s) and/or other

reviews conducted by outside entities at United Therapeutics’ request be substituted for one or more of the Additional Item reviews that would otherwise be conducted by the IRO for the applicable Reporting Period. OIG retains sole discretion over whether, and in what manner, to allow United Therapeutics’ internal audit work to be substituted for a portion of the Additional Items review conducted by the IRO.

In making its decision, OIG agrees to consider, among other factors, the nature and scope of United Therapeutics’ planned monitoring activities and internal audit work, the results of the Transactions Review(s) during prior Reporting Period(s), and United Therapeutics’ demonstrated audit capabilities to perform the proposed audit work internally. If OIG denies United Therapeutics’ request to permit its internal audit work to be substituted for a portion of the IRO’s review of Additional Items in a given Reporting Period, United Therapeutics shall engage the IRO to perform the Review as outlined in this Section IV.

If OIG agrees to permit certain of United Therapeutics’ internal audit work for a given Reporting Period to be substituted for a portion of an Additional Items review, such internal work may be subject to verification by the IRO (Verification Review). In such an instance, OIG would provide additional details about the scope of the Verification Review to be conducted by the IRO.
