 INDENTURE, dated as of May 12, 2015 among Quintiles Transnational Corp., a North Carolina
corporation (the “Issuer” or “Quintiles”), the Guarantors and U.S. Bank National Association, as trustee (the “Trustee”). 

Each party agrees as follows for the benefit of the other parties and for the equal and ratable benefit of the Holders of the Notes. 

ARTICLE ONE 
 DEFINITIONS AND
INCORPORATION BY REFERENCE 
 SECTION 1.01. Definitions. 

“Additional Notes” has the meaning set forth in Section 2.01. 

“Affiliate” of any specified Person means any other Person directly or indirectly controlling or controlled by or under
direct or indirect common control with such specified Person. For purposes of this definition, “control,” as used with respect to any Person, means the possession, directly or indirectly, of the power to direct or cause the direction of
the management or policies of such Person, whether through the ownership of voting securities, by agreement or otherwise. For purposes of this definition, the terms “controlling,” “controlled by” and “under common control
with” have correlative meanings. 
 “Agent” means any Registrar, Paying Agent, Transfer Agent or agent for service or
notices and demands. 
 “Agent Members” has the meaning set forth in Section 2.16. 

“amend” means to amend, supplement, restate, amend and restate or otherwise modify; and “amendment” shall
have a correlative meaning. 
 “Applicable Redemption Premium” means, with respect to any Note on any Redemption Date, the
excess of 
 (1) the present value at such Redemption Date of (x) the redemption price of such Note if such Note were redeemed on
May 15, 2018 plus (y) all required and unpaid interest payments due on such Note through May 15, 2018, in each case computed using a discount rate equal to the Treasury Rate at such Redemption Date plus 50 basis points, over 

(2) the then-outstanding principal amount of the Note. 

“Attributable Indebtedness” means, with respect to any Sale and Lease-Back Transaction, at the time of determination, the
lesser of (1) the sale price of the property so leased multiplied by a fraction the numerator of which is the remaining portion of the base 







 
term of the lease included in such transaction and the denominator of which is the base term of such lease, and (2) the total obligation (discounted to the present value at the implicit
interest factor, determined in accordance with GAAP, included in the rental payments) of the lessee for rental payments (other than amounts required to be paid on account of property taxes as well as maintenance, repairs, insurance, water rates and
other items which do not constitute payments for property rights) during the remaining portion of the base term of the lease included in such transaction. Notwithstanding the foregoing, if such Sale and Lease-Back Transaction results in a Capital
Lease Obligation, the amount of Indebtedness represented thereby will be determined in accordance with the definition of “Capital Lease Obligation.” 

“Authentication Order” has the meaning set forth in Section 2.01. 

“Authorized Person” means any person who is designated in writing by the Issuer from time to time to give Instructions to the
Trustee or Agent under the terms of this Indenture.

amended, or any similar federal, state, local or foreign law for the relief of debtors. 
 “Beneficial Owner” has the
meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under the Exchange Act, except that in calculating the beneficial ownership of any particular “person” (as that term is used in Section 13(d)(3) of the Exchange Act), such
“person” will be deemed to have beneficial ownership of all securities that such “person” has the right to acquire by conversion or exercise of other securities, whether such right is currently exercisable or is exercisable only
upon the occurrence of a subsequent condition. The terms “Beneficially Owns” and “Beneficially Owned” have a corresponding meaning. 

“Board of Directors” means: 

(1) with respect to a corporation, the board of directors of the corporation (or any duly authorized committee thereof); 

(2) with respect to a partnership, the Board of Directors (or any duly authorized committee thereof) of the general partner of the
partnership; 
 (3) with respect to a limited liability company, the managing member or members or any controlling committee of managing

“Business Day” has the meaning set forth in Section 11.07. 

  
 -2- 








 “Capital Lease Obligation” means, at the time any determination is to be made,
the amount of the liability in respect of a capital lease that would at that time be required to be capitalized and reflected as a liability on a balance sheet (excluding the footnotes thereto) prepared in accordance with GAAP.

(1) in the case of a corporation, corporate stock; 

(2) in the case of an association or business entity, any and all shares, interests, participations, rights or other equivalents (however

profits and losses of, or distributions of assets of, the issuing Person. 
 “Change of Control” means the occurrence of
any of the following: 
 (1) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of
merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of Quintiles and its Subsidiaries taken as a whole (other than any Qualified Securitization Transaction) to any
“person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than a Permitted Holder; 
 (2)
the adoption of a plan relating to the liquidation or dissolution of Quintiles; or 
 (3) Quintiles becomes aware of (by way
of a report or other filing pursuant to Section 13(d) of the Exchange Act, proxy, written notice or otherwise) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any
“person” (as defined above), other than the Permitted Holders, becomes the Beneficial Owner, directly or indirectly, of more than 50% of the Voting Stock of Quintiles, measured by voting power rather than number of shares. 

“Change of Control Offer” has the meaning set forth in Section 4.08.

rating of the Notes on any day during such Ratings Decline Period is below the rating by such Ratings Agency in effect immediately preceding the first public announcement of the Change of Control (or occurrence thereof, if such Change of Control
occurs prior to the first public announcement thereof); provided, however, that a downgrade of the Notes by the applicable Rating Agency will not be deemed to have occurred in respect of a Change of Control (and thus will not be deemed
a downgrade for purposes of this definition) if such Rating Agency making the reduction in rating does not publicly announce or confirm or inform Quintiles or the Trustee in writing at the request of Quintiles that the reduction was the result, in
whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the Change of Control (whether or not the applicable Change of Control has occurred at the time of such downgrade), or (y) the Notes do not
have an Investment Grade Rating from one or both Rating Agencies, a Change of Control. No Change of Control Triggering Event will be deemed to have occurred in connection with a Change of Control until such Change of Control has been consummated.

“Consolidated Net Income” means, for any period, with respect to any Person, net income attributable to such Person and its
Subsidiaries on a consolidated basis, as determined in accordance with GAAP; provided that Consolidated Net Income for any such period shall exclude, without duplication,

(vii) any net income or loss attributable to the early extinguishment of Indebtedness,

amortization or write-off of any such amounts, 
 (ix) any impairment charge or asset write-off or write-down, including
impairment charges or asset write-offs or write-downs related to intangible assets, long-lived assets, investments in debt and equity securities or obligations (including any losses with respect to obligations of customers, account debtors and

such Limited Condition Transaction are entered into (the “LCT Test Date”), and if, after giving pro forma effect to the Limited Condition Transaction and the other transactions

 SECTION 2.01. Amount of
Notes. 
 The Trustee shall initially authenticate $800,000,000 aggregate principal amount of Notes for original issue on the Issue Date
upon a written order of the Issuer (an “Authentication Order”). The Trustee shall thereafter authenticate additional Notes (other than Notes issued under Sections 2.07, 2.08, 2.11, 2.16 and 3.06) (“Additional
Notes”) in unlimited amount (so long as permitted by the terms of this Indenture) for original issue upon an Authentication Order in aggregate principal amount as specified in such Authentication Order (other than as provided in
Section 2.08). Each such Authentication Order shall specify the principal amount of Notes to be authenticated and the date on which the Notes are to be authenticated. 

SECTION 2.02. Form and Dating; Legends. 

The Notes and the Trustee’s certificate of authentication with respect thereto shall be substantially in the form set forth in Exhibit
A-1 (in the case of the Restricted Notes) and Exhibit A-2 (in the case of Unrestricted Notes), each of which is incorporated in and forms a part of this Indenture; provided that, to the
extent any provision of a Note conflicts with any provision of this Indenture, the provision of this Indenture shall govern. Each Note shall be dated the date of its authentication. 

  
 -25- 








 The Notes may have notations, legends or endorsements required by law, rule or usage to which the
Issuer is subject. Without limiting the generality of the foregoing, Notes offered and sold to Qualified Institutional Buyers in reliance on Rule 144A (“Rule 144A Notes”), Notes offered and sold in offshore transactions in reliance

Each Note issued hereunder that has more than a de minimis amount of original issue discount for U.S. Federal Income Tax purposes shall bear a
legend substantially in the form set forth on Exhibit D. 
 The terms and provisions contained in the Notes shall constitute, and are
expressly made, a part of this Indenture and, to the extent applicable, the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and agree to be bound thereby. 

The Notes may be presented for registration of transfer and exchange at the offices of the Registrar. 

SECTION 2.03. Execution and Authentication. 

The Notes shall be executed on behalf of the Issuer by at least one Officer of the Issuer. The signature of any such Officer on the Notes may
be manual, facsimile, .pdf attachment or other electronically transmitted signature. 
 If an Officer whose signature is on a Note was an
Officer at the time of such execution but no longer holds that office at the time the Trustee authenticates the Note, the Note shall be valid nevertheless. 

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly
authenticated and delivered hereunder. Notwithstanding the foregoing, if any Note shall have been authenticated and delivered hereunder but never issued and sold by the Issuer, and the Issuer shall deliver such Note to the Trustee for cancellation
as provided in Section 2.12, for all purposes of this Indenture such Note shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. 

The Trustee may appoint one or more authenticating agents reasonably acceptable to the Issuer to authenticate the Notes. Unless otherwise
provided in the appointment, an authenticating agent may authenticate the Notes whenever the Trustee may do so. 

  
 -26- 








 
Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Issuer and
Affiliates of the Issuer. Each Paying Agent is designated as an authenticating agent for purposes of this Indenture. 
 Notes shall be
issuable only in registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. 
 SECTION 2.04.
Registrar, Paying Agent and Transfer Agent. 
 The Issuer shall maintain (a) an office or agency where Notes may be presented for
registration of transfer or for exchange (the “Registrar”), (b) an office or agency in the United States where the Notes may be presented for payment (the “Paying Agent”), and (c) an office or agency to
act as transfer agent in respect of the Notes (the “Transfer Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Registrar shall provide a copy of such register from time to time upon
request of the Issuer. The Issuer may have one or more co-registrars, one or more additional paying agents and one or more co-transfer agents. The term “Registrar” includes any co-registrars. The term “Paying Agents” means the
Paying Agent and any additional paying agents. The term “Transfer Agent” includes any co-transfer agents. The Issuer or any Affiliate thereof may act as Registrar, a Paying Agent or a Transfer Agent. The Company may change or remove any
Registrar, Paying Agent or Transfer Agent without prior notice to the Holders. 
 The Issuer shall enter into an appropriate agency
agreement, which shall incorporate the provisions of the TIA, with any Agent that is not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Issuer shall notify the Trustee of the
name and address of any such Agent. If the Issuer fails to maintain a Registrar or any required co-registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such and shall be entitled to appropriate compensation in
accordance with Section 7.07. 
 The Issuer initially appoints the Trustee as Registrar, Paying Agent, Transfer Agent and agent for
service of notices and demands in connection with the Notes and this Indenture, and the Trustee hereby accepts such appointment. The Issuer initially appoints DTC to act as Depository with respect to the Global Notes. 

SECTION 2.05. Paying Agent To Hold Money. 

The Paying Agent shall hold for the Noteholders or the Trustee all money held by the Paying Agent for the payment of principal of or premium or
interest on the Notes (whether such money has been paid to it by the Issuer, one or more of the Guarantors or any other obligor on the Notes), and the Issuer and the Paying Agent shall notify the Trustee of any default by the Issuer (or any other
obligor on the Notes) in making any such payment. 

  
 -27- 








 
Money held by a Paying Agent need not be segregated except as required by law and in no event shall a Paying Agent be liable for any interest on any money received by it hereunder. The Issuer at
any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed and the Trustee may at any time during the continuance of any Event of Default specified in Section 6.01(1) or (2), upon written
request to a Paying Agent, require such Paying Agent to pay forthwith all money so held by it to the Trustee and to account for any funds disbursed. Upon making such payment, such Paying Agent shall have no further liability for the money delivered
to the Trustee. 
 SECTION 2.06. Noteholder Lists. 

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of
the Noteholders. If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee at least five Business Days before each Interest Payment Date, and at such other times as the Trustee may request in writing, a list in such form and as of
such date as the Trustee may reasonably require of the names and addresses of the Noteholders. 
 SECTION 2.07. Transfer and Exchange. 

Subject to Sections 2.16 and 2.17, when Notes are presented to the Registrar with a request from the Holder of such Notes to register a
transfer or to exchange them for an equal principal amount of Notes of other authorized denominations, the Registrar shall register the transfer as requested. Every Note presented or surrendered for registration of transfer or exchange shall be duly
endorsed or be accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Registrar, duly executed by the Holder thereof or his attorneys duly authorized in writing. To permit registrations of transfers and exchanges,
the Issuer shall issue and execute and, upon receipt of an Authentication Order in accordance with Section 2.01, the Trustee shall authenticate new Notes evidencing such transfer or exchange at the Registrar’s request. No service charge
shall be made to the Noteholder for any registration of transfer or exchange. The Issuer may require from the Noteholder payment of a sum sufficient to cover any transfer taxes or other governmental charge that may be imposed in relation to a
transfer or exchange, but this provision shall not apply to any exchange pursuant to Section 2.11, 3.06, 4.08, 4.12 or 8.05 (in which event the Issuer shall be responsible for the payment of such taxes). Neither the Issuer nor the Registrar
shall be required to transfer or exchange any Note or portion of a Note selected for redemption, except the unredeemed portion of any Note redeemed in part. Neither the Issuer nor the Registrar shall be required to transfer or exchange any Note
during the period beginning at the opening of business 15 days immediately preceding the mailing of notice of redemption of Notes pursuant to Section 3.03 and ending at the close of business on the day of such mailing. 

Any Holder of a Global Note shall, by acceptance of such Global Note, agree that transfers of the beneficial interests in such Global Note may
be effected only through a 

  
 -28- 








 
book entry system maintained by the Holder of such Global Note (or its agent), and that ownership of a beneficial interest in the Global Note shall be required to be reflected in a book entry. By
its acceptance of any Note bearing the Private Placement Legend, each Holder of such Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such
Note only as provided in this Indenture. 
 SECTION 2.08. Replacement Notes. 

If a mutilated Note is surrendered to the Registrar or the Trustee, or if the Holder of a Note claims that the Note has been lost, destroyed or
wrongfully taken, the Issuer shall issue and, upon receipt of an Authentication Order in accordance with Section 2.01, the Trustee shall authenticate a replacement Note if the Holder of such Note furnishes to the Issuer and the Trustee evidence
reasonably acceptable to them of the ownership and the destruction, loss or theft of such Note and if the requirements of Section 8-405 of the New York Uniform Commercial Code as in effect on the date of
this Indenture are met. If required by the Trustee or the Issuer, an indemnity bond shall be posted, sufficient in the judgment of all to protect the Issuer, the Guarantors, the Trustee, the Registrar, the Transfer Agent and any Paying Agent from
any loss that any of them may suffer if such Note is replaced. The Issuer may charge such Holder for the Issuer’s reasonable out-of-pocket expenses in replacing such Note and the Trustee may charge the Issuer for the Trustee’s
out-of-pocket expenses (including, without limitation, attorneys’ fees and disbursements) in replacing such Note. Every replacement Note shall constitute a contractual obligation of the Issuer. 

SECTION 2.09. Outstanding Notes. 
 The
Notes outstanding at any time are all Notes that have been authenticated by the Trustee except for (a) those canceled by or on behalf of the Trustee, (b) those delivered to the Trustee for cancellation, (c) to the extent set forth in
Sections 9.01 and 9.02, on or after the date on which the conditions set forth in Section 9.01 or 9.02 have been satisfied, those Notes theretofore authenticated by the Trustee hereunder and (d) those described in this
Section 2.09 as not outstanding. Subject to Section 2.10, a Note does not cease to be outstanding because the Issuer or one of its Affiliates holds the Note; provided, that Notes held by the Issuer or a Subsidiary of the Issuer will
be deemed not to be outstanding for purposes of paragraph 5(a)(1) of the Notes, except that in determining whether the Trustee shall be protected in relying upon any request, demand, authorization, direction, notice, consent or waiver, only Notes
that a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded. 
 If a Note is replaced pursuant to
Section 2.08, it ceases to be outstanding unless the Trustee receives proof satisfactory to the Trustee that the replaced Note is held by a bona fide purchaser in whose hands such Note is a legal, valid and binding obligation of the Issuer.


  
 -29- 








 If a Paying Agent holds, in its capacity as such, on any Maturity Date, U.S. Dollars sufficient
to pay all accrued interest and principal with respect to the Notes payable on that date and is not prohibited from paying such money to the Holders thereof pursuant to the terms of this Indenture, then on and after that date such Notes shall cease
to be outstanding and interest on them shall cease to accrue. 
 SECTION 2.10. Treasury Notes. 

In determining whether the Holders of the required principal amount of Notes have concurred in any declaration of acceleration or notice of
default or direction, waiver or consent or any amendment, modification or other change to this Indenture, Notes owned by the Issuer or any other Affiliate of the Issuer shall be disregarded as though they were not outstanding, except that for the
purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent or any amendment, modification or other change to this Indenture, only Notes as to which a Responsible Officer of the Trustee has
actually received an Officer’s Certificate stating that such Notes shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee established to the satisfaction of the Trustee the
pledgee’s right so to act with respect to the Notes and that the pledgee is not the Issuer, a Guarantor, any other obligor on the Notes or any of their respective Affiliates. 

SECTION 2.11. Temporary Notes. 
 Until
definitive Notes are prepared and ready for delivery, the Issuer may prepare and, upon receipt of an Authentication Order in accordance with Section 2.01, the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in
the form of definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and, upon receipt of an Authentication Order of the Issuer in the form of an
Officer’s Certificate in accordance with Section 2.01, the Trustee shall authenticate definitive Notes in exchange for temporary Notes. Until such exchange, temporary Notes shall be entitled to the same rights, benefits and privileges as
definitive Notes. 
 SECTION 2.12. Cancellation. 

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar, the Transfer Agent and the Paying Agent shall forward
to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. Upon the direction of the Issuer, the Trustee shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or
cancellation and shall dispose of such canceled Notes in its customary manner. The Trustee will deliver certification of cancelled Notes to the Issuer upon request. The Issuer may not reissue or resell or issue new Notes to replace Notes that the
Issuer has redeemed or paid, or that have been delivered to the Trustee for cancellation. 

  
 -30- 








 SECTION 2.13. Defaulted Interest. 

If the Issuer defaults on a payment of interest on the Notes, the Issuer shall pay the defaulted interest then borne by the Notes plus (to the
extent permitted by law) any interest payable on the defaulted interest, in accordance with the terms hereof, to the Persons who are Holders thereof on a subsequent special record date, which date shall be at least five Business Days prior to the
payment date. At least 10 days before such special record date, the Issuer (or, upon written request of the Issuer, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to each affected Noteholder a notice that
states the special record date, the payment date and the amount of defaulted interest, and interest payable on defaulted interest, if any, to be paid. The Issuer may make payment of any defaulted interest in any other lawful manner not inconsistent
with the requirements (if applicable) of any securities exchange on which the Notes may be listed and, upon such notice as may be required by such exchange, if, after written notice given by the Issuer to the Trustee of the proposed payment pursuant
to this sentence, such manner of payment shall be deemed practicable by the Trustee. 
 Notwithstanding the foregoing, any interest which is
paid prior to the expiration of the 30-day period set forth in Section 6.01(1) shall be paid to Holders as of the record date for the Interest Payment Date for which interest has not been paid. 

SECTION 2.14. CUSIP and ISIN Numbers. 

The Issuer in issuing the Notes may use “CUSIP” and “ISIN” numbers, and if so used, such CUSIP and ISIN numbers shall be
included in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP or ISIN numbers printed in the notice or on the
Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. Any such redemption or exchange shall be unaffected by any omission or inaccuracy of such CUSIP, ISIN or other identification numbers. The Issuer
shall promptly notify the Trustee, in writing, of any such CUSIP or ISIN number used by the Issuer in connection with the issuance of the Notes and of any change in any such CUSIP or ISIN number. 

SECTION 2.15. Deposit of Moneys. 
 Prior
to 11:00 A.M., New York City time, on each Interest Payment Date and Maturity Date, the Issuer shall have deposited with the Paying Agent in immediately available funds U.S. Dollars sufficient to make cash payments, if any, due on such Interest
Payment Date or Maturity Date, as the case may be. The principal and interest on Global Notes shall be payable to the Depository or its nominee, as the case may be, as the sole registered owner and the sole Holder of the Global Notes represented
thereby. The principal and interest on Physical Notes shall be payable, either in person, by wire transfer or by mail, at the office of the Paying Agent. Final payment of principal at maturity will only be made by the Trustee upon surrender of the
related Note to the Trustee at its Corporate Trust Office.

“Rule 144A Global Note”). Regulation S Notes initially shall be represented by one or more Notes in registered, global form without interest coupons (collectively, the “Regulation S Global Note”). The term

purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the
Depository or impair, as between the Depository and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note. 

(b) Transfers of Global Notes shall be limited to transfer in whole, but not in part, to the Depository, its successors or their respective
nominees. Interests of Beneficial Owners in the Global Notes may be transferred or exchanged for Physical Notes only in accordance with the applicable rules and procedures of the Depository and the provisions of Section 2.17. In addition, a
Global Note shall be exchangeable for Physical Notes (i) if requested by a holder of such interests upon receipt by the Trustee of written instructions from the Depository or its nominee on behalf of any Beneficial Owner and in accordance with
the rules and procedures of the Depository and provisions of Section 2.16, (ii) if the Depository notifies the Issuer that it (x) is unwilling or unable to continue as depository for such Global Note or (y) has ceased to
be a clearing agency registered under the Exchange Act, and the Issuer thereupon fails to appoint a successor depository within 120 days, (iii) if there shall have occurred and be continuing Default or Event of Default with respect to such
Global Note or (iv) if the Issuer determines that all Global Notes should be exchanged for Physical Notes and so notifies the Trustee and the Depository in writing; provided that in no event shall a Regulation S Global Note be exchanged
for a Physical Note prior to the expiration of the Restricted Period and the receipt of any certificates required by Regulation S. In all cases, Physical Notes delivered in exchange for any Global Note or beneficial interests therein shall be
registered in the names, and issued in any approved denominations, requested by or on behalf of the Depository in accordance with its customary procedures.

 (c) In connection with the transfer of a Global Note as an entirety to Beneficial Owners pursuant
to subsection (b) of this Section 2.16, such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Issuer shall execute and, upon receipt of an Authentication Order in accordance with Section 2.01, the
Trustee shall authenticate and deliver, to each Beneficial Owner identified by the Depository in writing in exchange for its beneficial interest in such Global Note, an equal aggregate principal amount of Physical Notes of authorized denominations.

price(s) (or the appropriate method for calculation thereof, if not then ascertainable), and deliver to the Trustee an Officer’s Certificate stating that such redemption will comply with the applicable conditions contained in paragraph 5 of the
Notes. Except as provided in Section 3.04, notice given to the Trustee pursuant to this Section 3.01 may not be revoked after the time that notice is given to Noteholders pursuant to Section 3.03. 

SECTION 3.02. Selection by Trustee of Notes To Be Redeemed. 

If less than all of the Notes are to be redeemed at any time, selection of such Notes for redemption will be made by the Trustee in compliance
with the requirements of the principal national securities exchange, if any, on which the Notes to be redeemed are listed or, if such Notes are not so listed, on a pro rata basis by lot or by such method as the Trustee deems fair and

 -41- 








 The notice shall identify the Notes to be redeemed (including the CUSIP and/or ISIN numbers
thereof) and shall state:

(2) the redemption price (or the appropriate method for calculation thereof, if not then ascertainable) and the amount of
premium and accrued interest to be paid; 
 (3) if any Note is being redeemed in part, the portion of the principal amount of
such Note to be redeemed and that, after the Redemption Date and upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued to the Holder upon cancellation of the surrendered Note; 

(4) the name and address of the Paying Agent; 

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

acceptable to the Trustee), the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s sole expense. 

The Issuer will calculate any Applicable Redemption Premium, and the Trustee shall have no duty to confirm or verify such calculation.

 -42- 








 
thereof pursuant to this Indenture may, at the Issuer’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of a public or private offering
for cash by the Issuer or other corporate transaction. Failure to give such notice or any defect in such notice to any Holder shall not affect the validity of the proceedings for the redemption of any other Note. If mailed in the manner herein
provided, such notice shall be conclusively presumed to have been given, whether or not a Holder receives such notice. 
 Upon surrender to
the Paying Agent, such Notes shall be paid at the redemption price, including any premium, plus interest accrued to the Redemption Date; provided that if the Redemption Date is after a regular record date and on or prior to the Interest
Payment Date, the accrued interest shall be payable to the Holder of the redeemed Notes registered on the relevant record date. 
 SECTION 3.05. Deposit
of Redemption Price. 
 On or prior to 11:00 A.M., New York City time (or such later time of day to which the Trustee may reasonably
agree), on each Redemption Date, the Issuer shall deposit with the Paying Agent U.S. Dollars sufficient to pay the redemption price of, including premium, if any, and accrued interest on any and all Notes to be redeemed on that date (other than
Notes or portions thereof called for redemption on that date which have been delivered by the Issuer to the Trustee for cancellation). The Paying Agent shall promptly return to the Issuer any money deposited with the Paying Agent in excess of the
amount necessary to pay such redemption price. 
 On and after any Redemption Date, if money sufficient to pay the redemption price of,
including premium, if any, and accrued interest on all Notes called for redemption shall have been made available in accordance with the immediately preceding paragraph, the Notes called for redemption will cease to accrue interest and the only
right of the Holders of such Notes will be to receive payment of the redemption price of and, subject to the second proviso in Section 3.04, accrued and unpaid interest on such Notes to (but not including) the Redemption Date. If any Note
surrendered for redemption shall not be so paid, interest will be paid, from the Redemption Date until such redemption payment is made, on the unpaid principal of the Note and any interest not paid on such unpaid principal, in each case at the rate
and in the manner provided in the Notes. 
 SECTION 3.06. Notes Redeemed in Part. 

Upon surrender of a Note that is redeemed in part, the Issuer shall execute and, upon receipt of an Authentication Order in accordance with
Section 2.01, the Trustee shall authenticate for the Holder thereof a new Note equal in principal amount to the unredeemed portion of the Note surrendered; provided, that the principal amount of each new Note shall be $2,000 or an
integral multiple of $1,000 in excess thereof.

become a Lien upon the property of the Issuer or any Guarantor; provided, however, that, neither Issuer nor any Guarantor shall be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim
where the failure to pay such tax is not materially adverse to the Holders or whose amount, applicability or validity is being contested in good faith and by appropriate actions diligently conducted, if adequate reserves with respect thereto are

Notes repurchased, to (but not including) the date of purchase. 
 (b) Within 30 days following any Change of Control Triggering Event or,
at Quintiles’ option, prior to any Change of Control, but after public announcement of the 

  
 -46- 








 
transaction that constitutes or may constitute the Change of Control, Quintiles will send or cause to be sent notice of such Change of Control Offer, with a copy to the Trustee and the Registrar,
by first-class mail, to each Holder to the address of such Holder appearing in the register maintained by the Registrar pursuant to Section 2.06 or otherwise in accordance with the procedures of the Depository, with the following information:

 (1) that a Change of Control Offer is being made pursuant to this Section 4.08 and that all Notes properly tendered
pursuant to such Change of Control Offer will be accepted for payment by Quintiles; 
 (2) the purchase price and the
purchase date, which will be no earlier than 30 days nor later than 60 days from the date such notice is mailed or, if the notice is mailed prior to the Change of Control, no earlier than 30 days and no later than 60 days after the date on which the
Change of Control Triggering Event occurs (the “Change of Control Payment Date”); 
 (3) that any Note not
properly tendered will remain outstanding and continue to accrue interest; 
 (4) that unless Quintiles defaults in the
payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on the Change of Control Payment Date; 

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender such
Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the Paying Agent specified in the notice at the address specified in the notice prior to the close of business on the third
Business Day preceding the Change of Control Payment Date; 
 (6) that Holders tendering less than all of their Notes will be
issued new Notes and such new Notes will be equal in principal amount to the unpurchased portion of the Notes surrendered; and 

(7) other instructions determined by Quintiles, consistent with this Section 4.08, that a Holder must follow to tender
Notes pursuant to such Change of Control Offer. 
 On the Change of Control Payment Date, Quintiles shall, to the extent lawful: 

(1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 

  
 -47- 








 (2) deposit with the Paying Agent an amount equal to the aggregate Change of
Control Payment in respect of all Notes or portions of Notes properly tendered; and 
 (3) deliver, or cause to be delivered,
to the Trustee for cancellation the Notes so accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by Quintiles. 

The Paying Agent will promptly send to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will be in a principal
amount of $2,000 or an integral multiple of $1,000 in excess thereof. 
 If the Change of Control Payment Date is on or after an interest
record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid on the Change of Control Payment Date to the Person in whose name a Note is registered at the close of business on such record
date, and no additional interest will be payable to Holders who tender pursuant to the Change of Control Offer. 
 (c) Upon the payment of
the Change of Control Payment, the Trustee shall, subject to the provisions of Section 2.16, return the Notes purchased to the Issuer for cancellation. The Trustee may act as the Paying Agent for purposes of any Change of Control Offer. 

(d) Quintiles shall not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes the
Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.08 applicable to a Change of Control Offer made by Quintiles and purchases all Notes properly tendered under the
Change of Control Offer. Any Change of Control Offer may be made in advance of a Change of Control Triggering Event, conditional upon such Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control at the
time of making of the Change of Control Offer. 
 (e) Quintiles shall comply with the requirements of Rule 14e-1 under the Exchange Act, and
any other securities laws and regulations thereunder, to the extent such laws or regulations are applicable in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Indenture, Quintiles shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof. Quintiles
may from time to time repurchase Notes other than pursuant to a Change of Control Offer or optional redemption, whether by tender offer, open market purchase, or otherwise, in accordance with applicable securities laws.

 SECTION 4.09. Limitation on Liens. 

Except as provided in Section 4.11, Quintiles shall not, and shall not permit any Guarantor to, incur, issue or assume any Indebtedness
for borrowed money secured by any Lien upon any of its Principal Personal & Real Property (whether now owned or hereafter acquired) without making effective provision whereby the Notes shall be secured equally and ratably with (or prior to)
the Indebtedness so secured by a Lien on the same property, for so long as such Indebtedness is so secured. The foregoing restrictions will not, however, apply to Indebtedness secured by Permitted Liens. 

For purposes of this Section 4.09, if at the time any Indebtedness is incurred, issued or assumed, such Indebtedness is unsecured but is
later secured by a Lien, such Indebtedness shall be deemed to be incurred at the time that such Indebtedness is so secured by a Lien. 
 SECTION 4.10.
Limitation on Sale and Leaseback Transactions. 
 Except as provided in Section 4.11, neither Quintiles nor any Guarantor shall
enter into any Sale and Lease-Back Transaction with respect to any Principal Personal & Real Property with another Person (other than with Quintiles or a Guarantor) unless: 

(1) Quintiles or such Guarantor could incur Indebtedness secured by a Lien on the property to be leased without equally and
ratably securing the Notes; or 
 (2) the property leased pursuant to such arrangement is sold for a price at least equal to
such property’s fair value (as determined by Quintiles); or 
 (3) within 270 days of the effective date of any such
Sale and Lease-Back Transaction, Quintiles applies the net proceeds of the sale of the leased property, less the amount of net proceeds used to prepay, redeem or purchase the Notes, to the voluntary prepayment or retirement of Funded Debt of
Quintiles and its Subsidiaries (which may include the Notes) and/or the acquisition, construction or improvement of a property. 
 SECTION 4.11. Exempted
Transactions. 
 Notwithstanding Sections 4.09 and 4.10, if (i) the aggregate outstanding principal amount of all Indebtedness
of Quintiles and the Guarantors that is subject to and not otherwise permitted under Section 4.09 plus (ii) the aggregate Attributable Indebtedness in respect of Sale and Lease-Back Transactions that is subject to and not otherwise
permitted under Section 4.10 does not exceed an amount that would cause the Consolidated Secured Debt Ratio to exceed 4.00 to 1.00 (measured solely at the time of the incurrence of the Indebtedness secured by such a Lien or entry into such Sale
and Lease-Back Transaction, as applicable, 

  
 -49- 








 
based on the consolidated balance sheet of Holdings as of the last day of the then most recent quarter for which financial statements are available), then: 

(1) Quintiles or any Guarantor may incur or Guarantee Indebtedness secured by Liens upon any property, assets or revenues; 

(2) Quintiles or any Guarantor may enter into any Sale and Lease-Back Transaction; and 

(3) Quintiles may Guarantee the obligations of any Guarantor under the preceding two clauses. 

SECTION 4.12. Reports to Holders. 
 (a) So
long as any Notes are outstanding, whether or not Holdings is required to file such information with the SEC, Quintiles shall furnish to the Trustee (and the Holders and Beneficial Owners of the Notes) to the extent not otherwise available on the
SEC’s Electronic Data Gathering, Analysis and Retrieval System (or any successor thereto) as promptly as is reasonably practicable after such information has been filed: 

(i) quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q
and 10-K if Quintiles were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual
financial statements by Quintiles’ certified independent accountants; and 
 (ii) all current reports that would be
required to be filed (as opposed to furnished) with the SEC on Form 8-K if Quintiles were required to file such reports. 
 (b) So long as
any Notes are outstanding, at any time that Holdings is not required to file or furnish with the SEC the reports and information required to be filed or furnished under clause (a) of this Section 4.12, Quintiles will also: 

(1) hold a quarterly conference call to discuss the information contained in the annual and quarterly reports required to be
furnished under clause (a) of this Section 4.12 (the “Financial Reports”) not later than 5 Business Days from the time Quintiles furnishes such information to the Trustee; 

(2) no fewer than 3 Business Days prior to the date of the conference call required to be held in accordance with clause
(1) above, issue a press release announcing, or utilize other means that will, in the reasonable judgment of Quintiles, advise Beneficial Owners of, the time and date of such conference call and directing


  
 -50- 








 
the Beneficial Owners of the Notes, prospective investors and securities analysts to contact the investor relations office of Holdings to obtain the Financial Reports and information on how to
access such conference call; and 
 (3) either (x) maintain a non-public website to which Beneficial Owners of the
Notes, prospective investors and securities analysts are given access and to which the Financial Reports and conference call access details are posted or (y) distribute via electronic mail the Financial Reports and conference call details to
Beneficial Owners of the Notes, prospective investors and securities analysts who request to receive such distributions. 
 (c) Quintiles
may satisfy its obligations under this Section 4.12 with respect to financial information relating to Quintiles by furnishing financial information relating to its direct or indirect parent consistent with this Section 4.12. If the direct
or indirect parent has more than de minimis operations separate and apart from its ownership in Quintiles, then Quintiles will be required to provide consolidating information, which need not be audited, that explains in reasonable detail the
differences between the information relating to such parent and its subsidiaries, on the one hand, and the information relating to Quintiles and its Subsidiaries on a standalone basis, on the other hand. 

(d) In addition, Quintiles will furnish to Holders or Beneficial Owners of the Notes and any prospective purchaser of such Notes, upon their
request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act if not otherwise provided by Quintiles or Holdings as described above. 

(e) Delivery of such reports and information to the Trustee shall be for informational purposes only, and the Trustee’s receipt of them
shall not constitute constructive notice of any information contained therein or determinable from information contained therein (including the Issuer’s compliance with any of its covenants under this Indenture, as to which the Trustee is
entitled to rely exclusively on an Officer’s Certificate). 

  
 -51- 








 SECTION 4.13. Additional Note Guarantees. 

(a) If Quintiles or any of its Subsidiaries acquires or creates another Subsidiary after the Issue Date that provides a guarantee of
Quintiles’ obligations under any Debt Facility (including the Credit Agreement) with an aggregate principal or committed amount of $300 million or more, then, within 10 Business Days after such Subsidiary provides such guarantee, such newly
acquired or created Subsidiary shall execute a supplemental indenture pursuant to which it will unconditionally Guarantee, on a joint and several basis, payment of principal of, premium, if any, and interest in respect of the Notes on a senior
unsecured basis on the same terms and conditions as those set forth in this Indenture, and will deliver an Opinion of Counsel addressed to the Trustee. 

(b) A Note Guarantee of any Guarantor shall be subject to release and discharge as provided under Article Ten.

form satisfactory to the Trustee; 
 (3) immediately after such transaction, on a pro forma basis giving effect to

Guarantor is merged or to which such sale, assignment, transfer, conveyance, lease or other disposition is made, shall succeed to, and be substituted for, and may exercise every right and power of, Quintiles or such Guarantor under this Indenture
(including the Note Guarantee or Notes, as applicable) with the same effect as if such successor had been named as Quintiles or such Guarantor herein and therein. When a successor assumes all the obligations of its predecessor under this Indenture
(including the Note Guarantee and Notes, as applicable) in accordance with the foregoing provisions, the predecessor shall be automatically released from those obligations.

Guarantee now exists, or is created after the Issue Date, if that default: 
 (a) is caused by a failure to pay principal of
such Indebtedness at its final stated maturity after giving effect to any grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or 

(b) results in the holders of such Indebtedness causing it to become due prior to its express maturity, 

without such Indebtedness having been discharged or such acceleration rescinded, waived or annulled within 30 days after the notice described
below, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $125
million or more; 
 (5) failure by Quintiles or any Guarantor to pay final, non-appealable judgments for the payment of money

 (6) (A) a court having jurisdiction
over the Issuer or any Guarantor that is a Significant Subsidiary enters (x) a decree or order for relief in respect of the Issuer or any Guarantor that is a Significant Subsidiary or group of Guarantors that, taken together, would constitute a
Significant Subsidiary in an involuntary case or proceeding under any Bankruptcy Law or (y) a decree or order adjudging Issuer or any Guarantor that is a Significant Subsidiary or group of Guarantors that, taken together, would constitute a
Significant Subsidiary as bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Issuer or any such Guarantor or group of Guarantors under any
Bankruptcy Law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Issuer or any such Guarantor or group of Guarantors or of any substantial part of its property, or ordering the winding

or disaffirm its obligations under its Note Guarantee. 
 Notwithstanding anything herein to the contrary, a Default under clause (3),
(4) or (5) will not become an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding notify Quintiles of the Default and Quintiles does not cure such default within the time
specified after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.” 

  
 -55- 








 SECTION 6.02. Acceleration of Maturity. 

If an Event of Default occurs and is continuing under this Indenture, either the Trustee, by notice in writing to the Issuer, or the Holders of
at least 25% in aggregate principal amount of the Notes then outstanding may, by notice in writing to the Issuer and the Trustee, specifying the respective Event of Default and that it is a “Notice of Acceleration”, declare the principal
of and premium, if any, and accrued interest, if any, on the Notes to be due and payable, and upon such declaration of acceleration, such principal of and premium, if any, and accrued interest, if any, shall be immediately due and payable;
provided, however, that, notwithstanding the foregoing, if an Event of Default specified in Section 6.01(6) occurs with respect to the Issuer, the principal of and premium, if any, and accrued interest, if any, on the Notes then
outstanding shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 
 SECTION 6.03.
Other Remedies. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any other available remedy by proceeding at
law or in equity to collect the payment of principal of, or premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture and may take any necessary action requested by the Holders of a
majority of the principal amount outstanding of the Notes to settle, compromise, adjust or otherwise conclude any proceedings to which it is a party. 

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay
or omission by the Trustee or any Noteholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any
other remedy. All available remedies are cumulative. Any reasonable costs associated with actions taken by the Trustee under this Section 6.03 shall be reimbursed to the Trustee by the Issuer and the Guarantors. 

SECTION 6.04. Rescission of Acceleration; Waiver of Existing Defaults and Events of Default. 

(a) Subject to Sections 2.10, 6.08 and 8.02, the Holders of a majority in principal amount of the Notes then outstanding shall have the right
to rescind an acceleration or waive past or continuing Defaults and Events of Default under this Indenture, except a continuing Default or Event of Default in the payment of the principal of, or interest or premium, if any, on any Note as
specified in clauses (1) and (2) of Section 6.01 (other than any payment Default or Event of Default that resulted from such acceleration) or in respect of a covenant or 

  
 -56- 








 
a provision which cannot be modified or amended without the consent of all Holders as provided for in Section 8.02. The Issuer shall deliver to the Trustee an Officer’s Certificate
stating that the requisite percentage of Holders have consented to such waiver or rescission and attaching copies of such consents. 
 In
the event of any Default or Event of Default specified in Section 6.01(4), such Default or Event of Default will be annulled, waived, and rescinded, automatically and without any action by the Trustee or the Holders, if within 20 days after
such Default or Event of Default arose: 
 (1) the Indebtedness or Guarantee that is the basis for such Default or Event of
Default has been discharged; 
 (2) the holders thereof have rescinded or waived the acceleration, notice or action (as the
case may be) giving rise to such Default or Event of Default; or 
 (3) the default that is the basis for such Default or
Event of Default has been cured. 
 In case of any waiver of a Default or Event of Default, the Issuer, the Trustee and the Holders shall be
restored to their former positions and rights hereunder and under the Notes, respectively. This subsection (a) of this Section 6.04 shall be in lieu of TIA § 316(a)(1)(B), and TIA § 316(a)(1)(B) is hereby expressly excluded
from this Indenture and the Notes, as permitted by the TIA. 
 (b) Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, but no such waiver or rescission shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto. 

SECTION 6.05. Control by Majority. 

Subject to Sections 2.10 and 7.01, the Holders of a majority in principal amount of the outstanding Notes have the right to direct the time,
method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on the Trustee by this Indenture. The Trustee, however, may refuse to follow any direction that conflicts
with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of another Holder not taking part in such direction, and the Trustee shall have the right to decline to follow any such direction if the Trustee, being
advised by counsel, determines that the action so directed may not lawfully be taken or if the Trustee in good faith shall, by a Responsible Officer, determine that the proceedings so directed may involve it in personal liability; provided
that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. In the event the 

  
 -57- 








 
Trustee takes any enforcement action or follows any such direction pursuant to this Indenture, the Trustee shall be entitled to indemnification reasonably satisfactory to it against any loss or
expense caused by taking such action or following such direction. This Section 6.05 shall be in lieu of TIA § 316(a)(1)(A), and TIA § 316(a)(1)(A) is hereby expressly excluded from this Indenture and the Notes, as permitted by the
TIA. 
 SECTION 6.06. Limitation on Suits. 

Subject to Section 6.08, a Holder may not enforce or pursue any remedy with respect to this Indenture or the Notes unless: 

(1) the Holder has given the Trustee written notice of a continuing Event of Default; 

(2) the Holders of at least 25% in principal amount of the Notes then outstanding make a written request to the Trustee to
pursue the remedy; 
 (3) such Holder or Holders offer the Trustee indemnity satisfactory to the Trustee against any costs,
liability or expense; 
 (4) the Trustee does not comply with the request within 60 days after receipt of the request and the
offer of indemnity; and 
 (5) during such 60-day period, the Holders of a majority in aggregate principal amount of the
outstanding Notes do not give the Trustee a direction that is inconsistent with the request. 
 A Noteholder may not use any provision of
this Indenture to disturb or prejudice the rights of another Noteholder or to obtain a preference or priority over another Noteholder. 
 SECTION 6.07.
No Personal Liability of Directors, Officers, Employees and Stockholders. 
 No director, officer, employee, incorporator or
stockholder of Quintiles or any Guarantor, as such, will have any liability for any obligations of Quintiles or the Guarantors under the Notes, this Indenture, the Note Guarantees, or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the
federal securities laws. 

  
 -58- 








 SECTION 6.08. Rights of Holders To Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of the principal of or premium, if
any, or interest, if any, on such Note on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment, on or after such respective due dates, is absolute and unconditional and shall not be
impaired or affected without the consent of the Holder. 
 SECTION 6.09. Collection Suit by Trustee. 

If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name
and as trustee of an express trust against the Issuer or any Guarantor (or any other obligor on the Notes) for the whole amount of unpaid principal and accrued interest remaining unpaid, together with interest on overdue principal and, to the extent
that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate set forth in the Notes, and such further amounts as shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 SECTION 6.10. Trustee May File Proofs of
Claim. 
 The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07) and the Noteholders allowed in
any judicial proceedings relative to the Issuer or any Guarantor (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on
any such claims and to distribute the same after deduction of its charges and expenses to the extent that any such charges and expenses are not paid out of the estate in any such proceedings and any custodian in any such judicial proceeding is
hereby authorized by each Noteholder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Noteholders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. 

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Noteholder
any plan or reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Noteholder thereof, or to authorize the Trustee to vote in respect of the claim of any Noteholder in any such proceedings.

 SECTION 6.11. Priorities. 

If the Trustee collects any money or property pursuant to this Article Six, it shall pay out the money and property in the following
order: 
 FIRST: to the Trustee for amounts due under Section 7.07; 

SECOND: to Noteholders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without
preference or priority of any kind, according to the amounts due and payable; and 
 THIRD: to the Issuer or, to the extent
the Trustee collects any amount from any Guarantor, to such Guarantor, or as a court of competent jurisdiction may direct. 
 The Trustee
may fix a record date and payment date for any payment to Noteholders pursuant to this Section 6.11. 
 SECTION 6.12. Undertaking for Costs.

 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or
omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable
attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.12 does not apply to a suit by the Trustee, a suit by
a Noteholder pursuant to Section 6.08 or a suit by Holders of more than 10% in aggregate principal amount of the outstanding Notes. 

ARTICLE SEVEN 
 TRUSTEE 

SECTION 7.01. Duties of Trustee. 
 (a) If
a Default or Event of Default actually known to a Responsible Officer of the Trustee has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent person would exercise or use under the same circumstances in the conduct of his or her own affairs. 
 The
Trustee shall not be deemed to have actual knowledge of any Default or Event of Default unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice
references the Notes and this Indenture and states that such notice is a “Notice of Default.” 

  
 -60- 








 (b) Except during the continuance of a Default or an Event of Default of which a Responsible
Officer of the Trustee has actual knowledge: 
 (1) The Trustee need perform only those duties expressly set forth in this
Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee. 
 (2) In the
absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements
of this Indenture but, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they
conform on their face to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). Whenever in the administration of this Indenture the Trustee shall deem it
desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon
an Officer’s Certificate, subject to the requirement in the preceding sentence, if applicable. 
 (c) The Trustee may not be relieved
from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 

(1) This paragraph does not limit the effect of subsection (b) of this Section 7.01. 

(2) The Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved
that the Trustee was negligent in ascertaining the pertinent facts. 
 (3) The Trustee shall not be liable with respect to
any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to the terms of this Indenture. 

(4) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its rights, powers or duties if the Trustee shall have reasonable grounds for believing that repayment of such funds or indemnity satisfactory to it against such risk or liability is not reasonably assured.


  
 -61- 








 (d) Whether or not therein expressly so provided, subsections (a), (b), (c) and (e) of
this Section 7.01 shall govern every provision of this Indenture that in any way relates to the Trustee. 
 (e) The Trustee shall be
under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have fully indemnified the Trustee to the satisfaction
of the Trustee, against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction (including, but not limited to, the fees and disbursements of agents and attorneys). 

(f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuer or any
Guarantor. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by the law.

(4) The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any
attorney or agent appointed by it with due care. 

  
 -62- 








 (5) The Trustee shall not be liable for any action it takes or omits to take in
good faith which it reasonably believes to be authorized or within its rights or powers; provided that the Trustee’s conduct does not constitute negligence or willful misconduct. 

(6) The Trustee may consult with counsel of its selection, and the advice or opinion of such counsel as to matters of law shall

performed in accordance with all of the provisions in this Indenture, unless notified to the contrary. 
 (13) Under no
circumstances will the Trustee be liable for any indirect, special, punitive consequential loss or damage (including loss of business, goodwill, opportunity or profit), even if advised of the likelihood or possibility of such loss or damage and
regardless of the form of action. 
 SECTION 7.03. Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may make loans to, accept deposits from,
perform services for or otherwise deal with either the Issuer or any Guarantor, or any Affiliates thereof, with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as
described in Section 310(b) of the TIA), it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as Trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like
rights. The Trustee shall also be subject to Sections 7.10 and 7.11. 
 SECTION 7.04. Trustee’s Disclaimer. 

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes or any Note

to each Noteholder a notice of the Default or Event of Default within 90 days after it occurs in the manner and to the extent provided in the TIA and otherwise as provided in this Indenture. Except in the case of a Default or an Event of Default
relating to the payment of the principal of or interest on any Note (including payments pursuant to a redemption or repurchase of the Notes pursuant to the provisions of this Indenture), the Trustee may withhold the notice if and so long as a
Responsible Officer in good faith determines that withholding the notice is in the interests of Holders. 

  
 -64- 








 SECTION 7.06. Reports by Trustee to Holders. 

If required by TIA § 313(a), within 60 days after [May 1]1 of any year,
commencing on the [May 1] following the date of this Indenture, the Trustee shall mail to each Noteholder a brief report dated as of such date that complies with TIA § 313(a). The Trustee also shall comply with TIA
§ 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA § 313(c) and TIA § 313(d). 

Reports pursuant to this Section 7.06 shall be transmitted by mail: 

(1) to all Holders of Notes, as the names and addresses of such Holders appear on the Registrar’s books; and 

(2) to such Holders of Notes as have, within the two years preceding such transmission, filed their names and addresses with
the Trustee for that purpose. 
 SECTION 7.07. Compensation and Indemnity. 

The Issuer and the Guarantors shall pay to the Trustee from time to time reasonable compensation as agreed upon for its services hereunder
(which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust). The Issuer and the Guarantors shall reimburse the Trustee upon request for all reasonable out-of-pocket disbursements,
expenses and advances incurred or made by it in connection with the Trustee’s duties under this Indenture, including, but not limited to, the reasonable compensation, disbursements and expenses of the Trustee’s agents and external counsel.

 The Issuer and the Guarantors, jointly and severally, shall indemnify each of the Trustee and its agents, employees, directors and
officers and hold each of them harmless against, any and all loss, damage, claim, liability or expense, including without limitation taxes (other than taxes based on the income of the Trustee) and reasonable attorneys’ fees and expenses
incurred by each of them in connection with the acceptance or performance of its duties under this Indenture and including the reasonable costs and expenses of defending itself against any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder (including, without limitation, settlement costs and including claims by or against the Issuer or any Guarantor). The Trustee shall notify the Issuer and the Guarantors in writing promptly of any
claim of which a Responsible Officer of the Trustee has actual knowledge asserted against the Trustee for which it may seek indemnity; provided that the failure by the Trustee to so notify the Issuer and the Guarantors shall not relieve the

  
  

	1 	 Trustee to confirm. 



  
 -65- 








 
Issuer and Guarantors of their obligations hereunder except to the extent the Issuer or any Guarantor is actually prejudiced thereby. If there is an actual or potential conflict of interest, the
Trustee may have separate counsel and the Issuer shall pay the reasonable fees and expenses of such counsel. 
 Notwithstanding the
foregoing, the Issuer and the Guarantors need not pay for any settlement made without the Issuer’s consent or reimburse the Trustee for any expense or indemnify or hold it harmless against any loss, damage, claim or liability incurred by the
Trustee through its own negligence, bad faith or willful misconduct. 
 To secure the payment obligations of the Issuer and the Guarantors
in this Section 7.07, the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee except for such money or property held in trust to pay principal of and interest on particular Notes. Such lien
shall survive the satisfaction and discharge of this Indenture. 
 The obligations of the Issuer and the Guarantors under this
Section 7.07 to compensate and indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be joint and several liabilities of the Issuer and each of the Guarantors and shall survive the resignation
or removal of the Trustee and the satisfaction, discharge or other termination of this Indenture, including any termination or rejection hereof under any Bankruptcy Law. 

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(6) occurs, the expenses and the
compensation for the services are intended to constitute expenses of administration under any applicable Bankruptcy Law. 
 For purposes of
this Section 7.07, the term “Trustee” shall include any trustee appointed pursuant to this Article Seven. The provisions of this Section 7.07 shall apply to Trustee in its capacity as Paying Agent, Transfer Agent or
Registrar and any other Agent under this Indenture. 
 The provisions of this Section 7.07 shall survive the satisfaction and discharge
of this Indenture. 
 SECTION 7.08. Replacement of Trustee. 

The Trustee may resign at any time by so notifying the Issuer and the Guarantors in writing. The Holders of a majority in principal amount of
the outstanding Notes may remove the Trustee by notifying the Issuer and the removed Trustee in writing and may appoint a successor Trustee with the Issuer’s written consent, which consent shall not be unreasonably withheld. The Issuer may
remove the Trustee if: 
 (1) the Trustee fails to comply with Section 7.10; 

  
 -66- 








 (2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is
entered with respect to the Trustee under any Bankruptcy Law; 
 (3) a receiver or other public officer takes charge of the
Trustee or its property; or 
 (4) the Trustee otherwise becomes incapable of acting. 

Such resignation or removal shall become effective as provided below. 

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer shall promptly appoint a
successor Trustee. 
 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the
retiring Trustee, the Issuer or the Holders of a majority in principal amount of the outstanding Notes may petition at the expense of the Issuer any court of competent jurisdiction for the appointment of a successor Trustee; provided that if
the retiring Trustee resigns and a court has not appointed a successor within 60 days, such retiring Trustee may appoint a successor that meets the eligibility requirements of Section 7.10. 

If the Trustee fails to comply with Section 7.10, Noteholders holding at least 10% in principal amount of the Notes may petition any
court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 A successor Trustee shall
deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Immediately following such delivery, the retiring Trustee shall, subject to its rights under Section 7.07, transfer all property held by it as Trustee to
the successor Trustee, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail notice of
its succession to each Noteholder. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuer’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

Any corporation into which the Trustee may be merged or converted, or any corporation with which the Trustee may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation, including affiliated corporations, to which the Trustee shall sell or otherwise transfer: (a) all or substantially all
of its assets or (b) all or substantially all of its corporate trust business shall, on the date when the merger, conversion, consolidation or transfer becomes effective

execution or filing of any paper or any further act on the part of the parties to this Indenture, and after the said effective date all references in this Indenture to the Trustee shall be deemed to be references to such successor corporation.
Written notice of any such merger, conversion, consolidation or transfer shall be given to the Issuer by the Trustee promptly thereafter and such selling, transferring or successor Trustee shall execute such acknowledgement or other documents as the
Issuer reasonably requests. 
 SECTION 7.10. Eligibility; Disqualification. 

This Indenture shall always have a Trustee who satisfies the requirements of TIA § 310(a)(1) and (2) in every respect. The
Trustee shall have a combined capital and surplus of at least $100,000,000 as set forth in the most recent applicable published annual report of condition. The Trustee shall comply with TIA § 310(b); provided, however, that
there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Issuer are outstanding if the requirements for such
exclusion set forth in TIA § 310(b)(1) are met. 
 SECTION 7.11. Preferential Collection of Claims Against Issuer. 

The Trustee is subject to and shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A
Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 
 SECTION 7.12. Paying Agents.

Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 7.12: 

(A) that it will hold all sums held by it as agent for the payment of principal of, or premium, if any, or interest on, the
Notes (whether such sums have been paid to it by the Issuer or by any obligor on the Notes) in trust for the benefit of Holders of the Notes or the Trustee; 

(B) that it will at any time during the continuance of any Event of Default, upon written request from the Trustee, deliver to
the Trustee all sums so held in trust by it together with a full accounting thereof; and 
 (C) that it will give the Trustee
written notice within three Business Days of any failure of the Issuer (or by any obligor on the Notes) in the payment of any installment of the principal of, premium, if any, or interest on, the Notes when the same shall be due and payable. 

  
 -68- 








 SECTION 7.13. Communications. 

In no event shall the Trustee or any other entity of U.S. Bank National Association be liable for any Losses arising to the Trustee or any
other entity of U.S. Bank National Association receiving or transmitting any data from any Issuer, any Authorized Person or any party to the transaction via any non-secure method of transmission or communication, such as, but without limitation, by
facsimile or email. 
 The parties hereto accept that some methods of communication are not secure and the Agent or any other entity of U.S.
Bank National Association shall incur no liability for receiving instructions via any such non-secure method. The Agent or any other entity of U.S. Bank National Association is authorized to comply with and rely upon any such notice, instructions or
other communications believed by it to have been sent or given by an Authorized Person or an appropriate party to the transaction (or authorized representative thereof). The Issuer or authorized officer of the Issuer shall use all reasonable
endeavors to ensure that instructions transmitted to the Agent or any other entity of U.S. Bank National Association pursuant to this Indenture are complete and correct. Any instructions shall be conclusively deemed to be valid instructions from the

If an amendment, supplement, or waiver changes the terms of a Note, the Trustee (upon and in accordance with the specific written direction of
the Issuer) shall request the Holder of the Note (in accordance with the specific written direction of the Issuer) to deliver it to the Trustee. In such case, the Trustee shall place an appropriate notation on the Note about the changed terms and

This Indenture will be discharged and will cease to be of further effect as to all Notes and Note Guarantees, and the Trustee, at the request

(1) either: 

(A) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes

become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and Quintiles or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds
in trust solely for the benefit of the Holders, cash in U.S. Dollars, U.S. Government Obligations, or a combination of cash in U.S. Dollars and U.S. Government Obligations, in such amounts as will be sufficient without consideration of any

respect to the outstanding Notes and Note Guarantees on a date the conditions set forth in Section 9.04 are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that the Issuer will be
deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes and Note Guarantees and to have satisfied all their other obligations under such Notes, Note Guarantees and this Indenture (and the Trustee, at the
request and expense of the Issuer, shall, subject to Section 9.06, execute instruments in form and substance reasonably satisfactory to the Trustee and the Issuer acknowledging the same), except for the following which


  
 -74- 








 
shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of outstanding Notes to receive, solely from the trust funds described in Section 9.04 and as
more fully set forth in Section 9.04, payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due, (2) the Issuer’s obligations with respect to such Notes under Article Two and
Sections 4.02 and 4.05, (3) the rights, powers, trusts, duties, and immunities of the Trustee hereunder (including claims of, or payments to, the Trustee under or pursuant to Section 7.07) and the Issuer’s obligations in connection
therewith and (4) this Article Nine. 
 Subject to compliance with this Article Nine, the Issuer may exercise its option under
this Section 9.02 with respect to the Notes notwithstanding the prior exercise of its option under Section 9.03 below with respect to the Notes. 

SECTION 9.03. Covenant Defeasance. 
 The
Issuer may, at its option and at any time, elect to have all of its obligations and the obligations of the Guarantors under Sections 4.03 and 4.06 through 4.13 (except for obligations mandated by the TIA) and clause (3) of
Section 5.01(a) released with respect to the outstanding Notes and Note Guarantees on a date the conditions set forth in Section 9.04 are satisfied (hereinafter, “Covenant Defeasance”). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Issuer may fail to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document, and such omission to comply shall not constitute a Default or an
Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture, the Notes and the Note Guarantees shall be unaffected thereby. In addition, upon the Issuer’s exercise of the option in this
Section 9.03, subject to the satisfaction of the conditions set forth in Section 9.04, Sections 6.01(3), (4), (5), (6) (solely with respect to any Guarantor that is a Significant Subsidiary or any group of Guarantors that, taken
together, would constitute a Significant Subsidiary) and (7) shall not constitute Events of Default. 
 Notwithstanding any discharge
or release of any obligations under this Indenture pursuant to Section 9.02 or this Section 9.03, the Issuer’s obligations in Article Two and Sections 7.07, 9.05, 9.06, 9.07 and 9.08 shall survive until such time as the Notes have
been paid in full. Thereafter, the Issuer’s obligations in Sections 7.07, 9.05, 9.07 and 9.08 shall survive. 

  
 -75- 








 SECTION 9.04. Conditions to Legal Defeasance or Covenant Defeasance. 

The following shall be the conditions to application of Section 9.02 or Section 9.03 to the outstanding Notes: 

(1) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. Dollars, U.S.
Government Obligations or a combination thereof in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants (such opinion shall be addressed and delivered to the Trustee, and upon which the
Trustee shall have no liability in relying), to pay the principal, premium, if any, and interest on the Notes outstanding under this Indenture on the stated maturity date or on the applicable Redemption Date, as the case may be, and the Issuer must
specify whether such Notes are being defeased to maturity or to a particular Redemption Date; 
 (2) in the case of Legal
Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States (upon which the Trustee shall have no liability in relying) confirming that (a) the Issuer has received from, or there has been published by,
the Internal Revenue Service a ruling or (b) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders
will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such
Legal Defeasance had not occurred; 
 (3) in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee
an Opinion of Counsel in the United States (upon which the Trustee shall have no liability in relying) confirming that the Holders of the Notes outstanding under this Indenture will not recognize income, gain or loss for federal income tax purposes
as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or
Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing); 

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any
material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its
Subsidiaries is bound; 
 (6) the Issuer must deliver to the Trustee an Officer’s Certificate (upon which the Trustee
shall have no liability in relying) stating that the deposit was not made by the Issuer with the intent of preferring the Holders over the other creditors of the Issuer with the intent of defeating, hindering, delaying or defrauding creditors of the
Issuer or others; and 

  
 -76- 








 (7) the Issuer must deliver to the Trustee an Officer’s Certificate and an
Opinion of Counsel (upon which the Trustee shall have no liability in relying), each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 

Notwithstanding the foregoing, the Opinion of Counsel required by clause (2) above with respect to a Legal Defeasance need not be
delivered if all Notes not theretofore delivered to the Trustee for cancellation (x) have become due and payable or (y) will become due and payable on the maturity date within one year under arrangements satisfactory to the Trustee for the
giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer. 
 SECTION 9.05. Deposited Money and U.S. Government
Obligations To Be Held in Trust. 
 Subject to Section 9.08, all money and U.S. Government Obligations (including the proceeds
thereof) deposited with the Trustee pursuant to Sections 9.01 and 9.04 in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either
directly or through any Paying Agents, to the Holders of such Notes, of all sums due and to become due thereon in respect of principal, premium, if any, and accrued interest, but such money need not be segregated from other funds except to the
extent required by law. 
 The Issuer and the Guarantors shall (on a joint and several basis) pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Sections 9.01 and 9.04 or the principal, premium, if any, and interest received in respect thereof other than any such tax, fee or other charge
which by law is for the account of the Holders of the outstanding Notes. 
 Anything in this Article Nine to the contrary
notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time upon a request of the Issuer any money or U.S. Government Obligations held by it as provided in Sections 9.01 and 9.04 which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent satisfaction and discharge, Legal
Defeasance or Covenant Defeasance. 

  
 -77- 








 SECTION 9.06. Reinstatement. 

If the Trustee or any Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 9.01, 9.02 or
9.03 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s and each Guarantor’s obligations under this
Indenture, the Notes and the Note Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Article Nine until such time as the Trustee or such Paying Agent is permitted to apply all such money or U.S.
Government Obligations in accordance with Section 9.01, 9.02 or 9.03; provided that if the Issuer or the Guarantors have made any payment of principal of, premium, if any, or accrued interest on any Notes because of the reinstatement of
their obligations, the Issuer or the Guarantors, as the case may be, shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or any Paying Agent. 

SECTION 9.07. Moneys Held by Paying Agent. 

In connection with the satisfaction and discharge or defeasance of this Indenture, all moneys and U.S. Government Obligations then held by any
Paying Agent under the provisions of this Indenture shall, upon written demand of the Issuer, be paid or delivered to the Trustee, or if sufficient moneys and U.S. Government Obligations have been deposited pursuant to Section 9.01 or 9.04, as
the case may be, to the Issuer (or, if such moneys and U.S. Government Obligations were deposited by the Guarantors, to such Guarantors) within five Business Days after a request of the Issuer, and thereupon such Paying Agent shall be released from
all further liability with respect to such moneys. 
 SECTION 9.08. Moneys Held by Trustee. 

Subject to applicable law, any moneys and U.S. Government Obligations deposited with the Trustee or any Paying Agent or then held by the Issuer
or the Guarantors in trust for the payment of the principal of, or premium, if any, or interest on any Note that are not applied but remain unclaimed by the Holder of such Note for two years after the date upon which the principal of, or premium, if
any, or interest on such Note shall have respectively become due and payable shall be repaid or returned to the Issuer (or, if appropriate, the Guarantors) upon a request of the Issuer, or if such moneys and U.S. Government Obligations are then held
by the Issuer or the Guarantors in trust, such moneys and U.S. Government Obligations shall be released from such trust; and the Holder of such Note entitled to receive such payment shall thereafter, as an unsecured general creditor, look only to
the Issuer and the Guarantors for the payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust moneys and U.S. Government Obligations shall thereupon cease; provided that the Trustee or any such Paying
Agent, before being required to make any such repayment, may, at the expense of the Issuer and the Guarantors, either mail to each Noteholder 

  
 -78- 








 
affected, at the address shown in the register of the Notes maintained by the Registrar pursuant to Section 2.06, or cause to be published once, in one newspaper published in the English
language, customarily published each Business Day and of general circulation in The City of New York, the State of New York, a notice that such moneys and U.S. Government Obligations remain unclaimed and that, after a date specified therein, which
shall not be less than 30 days from the date of such mailing or publication, any unclaimed balance of such moneys and U.S. Government Obligations then remaining will be repaid or returned to the Issuer. After payment or return to the Issuer or the
Guarantors or the release of any moneys and U.S. Government Obligations held in trust by the Issuer or any Guarantors, as the case may be, Holders entitled thereto must look only to the Issuer and the Guarantors for payment as general creditors
unless applicable abandoned property law designates another Person. 
 ARTICLE TEN 

GUARANTEE OF SECURITIES 
 SECTION 10.01.
Guarantee. 
 The Guarantors, by execution of this Indenture, jointly and severally, guarantee to each Holder (i) the due and
punctual payment of the principal of, premium, if any, and interest on each Note, when and as the same shall become due and payable, whether at maturity, by acceleration or otherwise, the due and punctual payment of interest on the overdue principal
of and interest on the Notes, to the extent lawful, and the due and punctual payment of all other obligations and due and punctual performance of all obligations of the Issuer to the Holders or the Trustee all in accordance with the terms of such
Note and this Indenture and (ii) in the case of any extension of time of payment or renewal of any Notes or any of such other obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, at stated maturity, by acceleration or otherwise. Each Guarantor, by execution of this Indenture, agrees that, subject only to the applicable provisions, if any, of Section 10.03 or 10.06, its obligations hereunder shall
be absolute and unconditional, irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of any such Note or this Indenture, any failure to enforce the provisions of any such Note or this Indenture, any waiver,
modification or indulgence granted to the Issuer with respect thereto by the Holder of such Note, or any other circumstances which may otherwise constitute a legal or equitable discharge of a surety or such Guarantor. 

Each Guarantor hereby waives diligence, presentment, demand for payment, filing of claims with a court in the event of merger or bankruptcy of
the Issuer, any right to require a proceeding first against the Issuer, protest or notice with respect to any such Note or the Indebtedness evidenced thereby and all demands whatsoever, and covenants that this Guarantee will not be discharged as to
any such Note except by payment in full of the principal thereof and interest thereon. Each Guarantor hereby agrees that, as between such Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the


  
 -79- 








 
obligations guaranteed hereby may be accelerated as provided in Article Six for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such obligations as provided in Article Six, such obligations (whether or not due and payable) shall forthwith become due
and payable by each Guarantor for the purpose of this Guarantee. 
 The Guarantors shall have the right to seek contribution from any
non-paying Guarantor so long as the exercise of such right does not impair the rights of any Holder under the Note Guarantees. 
 SECTION 10.02.
Execution and Delivery of Note Guarantee. 
 To evidence its Note Guarantee set forth in Section 10.01, each Guarantor hereby
agrees that this Indenture shall be executed by either manual, facsimile, .pdf attachment or other electronically transmitted signature of an Officer on behalf of such Guarantor. The validity and enforceability of any Note Guarantee shall not be
affected by the fact that it is not affixed to any particular Note. 
 Each of the Guarantors hereby agrees that its Note Guarantee set
forth in Section 10.01 shall be in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. 

If an Officer of a Guarantor whose signature is on this Indenture or a Note Guarantee no longer holds that office at the time the Trustee
authenticates the Note on which such Note Guarantee is endorsed or at any time thereafter, such Guarantor’s Guarantee of such Note shall be valid nevertheless. 

The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Note Guarantee set
forth in this Indenture on behalf of the Guarantor. 
 SECTION 10.03. Release of Guarantors. 

(a) The Note Guarantee of a Guarantor will be automatically and unconditionally released, and any Person acquiring assets (including by way of
merger or consolidation) or Capital Stock of a Guarantor shall not be required to assume the obligations of any such Guarantor: 

(1) in connection with any sale, exchange, transfer, conveyance or other disposition of (whether by merger, consolidation or
the sale of) a majority of the Capital Stock of such Guarantor (or such lesser portion as is sufficient for such Guarantor to cease to be a Subsidiary of Quintiles) or the sale of all or substantially all the assets of such Guarantor, to or with and
into a Person which is not Quintiles or another Subsidiary of Quintiles; 

  
 -80- 








 (2) if any Guarantor is dissolved or otherwise no longer obligated to provide a
Note Guarantee pursuant to this Indenture; 
 (3) if such Guarantor’s guarantee of any obligations under any Debt
Facility of Quintiles (including the Credit Agreement) with an aggregate principal or committed amount of $300 million or more is fully and unconditionally released, except that such Guarantor shall subsequently be required to become a Guarantor by
executing a supplemental indenture and providing the Trustee with an Officer’s Certificate and Opinion of Counsel at such time as it guarantees any obligations under any Debt Facility of Quintiles (including the Credit Agreement) with aggregate
principal or committed amount of $300 million or more; or 
 (4) upon Quintiles’ exercise of its legal defeasance option
or covenant defeasance option as described in Section 9.02 or Section 9.03 or if Quintiles’ obligations under this Indenture and the Notes are discharged in accordance with Section 9.01. 

(b) The Trustee shall execute any documents reasonably requested by either the Issuer or a Guarantor in order to evidence the release of such
Guarantor from its obligations under its Guarantee under this Article Ten, subject to the Trustee’s receipt of an Opinion of Counsel and Officer’s Certificates stating that all conditions precedent to such release have been met. 

SECTION 10.04. Waiver of Subrogation. 

Each Guarantor hereby irrevocably waives, until payment in full of the Issuer’s obligations hereunder, any claim or other rights which it
may now or hereafter acquire against the Issuer that arise from the existence, payment, performance or enforcement of such Guarantor’s obligations under its Note Guarantee and this Indenture, including, without limitation, any right of
subrogation, reimbursement, exoneration, indemnification, and any right to participate in any claim or remedy of any Holder of Notes against the Issuer, whether or not such claim, remedy or right arises in equity, or under contract, statute or
common law, including, without limitation, the right to take or receive from the Issuer, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or Note on account of such claim or other rights. If any amount
shall be paid to any Guarantor in violation of the preceding sentence and the Notes shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the benefit of, and held in trust for the benefit of,
the Holders of the Notes, and shall forthwith be paid to the Trustee for the benefit of such Holders to be credited and applied upon the Notes, whether matured or unmatured, in accordance with the terms of this Indenture. Each Guarantor acknowledges
that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this Section 10.04 is knowingly made in contemplation of such benefits. 

  
 -81- 








 SECTION 10.05. Notice to Trustee. 

Notwithstanding the provisions of this Article Ten or any other provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect of the Note Guarantees, unless and until the Trustee shall have received written notice thereof from the Issuer no later than one Business Day
prior to such payment; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of this Section 10.05, and subject to the provisions of Sections 7.01 and 7.02, shall be entitled in all respects to assume
that no such facts exist; provided, however, that if the Trustee shall not have received the notice referred to in this Section 10.05 at least one Business Day prior to the date upon which by the terms hereof any such payment may
become payable for any purpose under this Indenture (including, without limitation, the payment of the principal of, premium, if any, or interest on any Note), then, anything herein contained to the contrary notwithstanding, the Trustee shall have
full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it less than one Business Day prior to such date.

 SECTION 10.06. Limitation on Guarantor’s Liability. 

Each Guarantor, and by its acceptance hereof, each Holder and the Trustee, hereby confirm that it is the intention of all such parties that the
Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Title 11 of the United States Code, as amended, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar U.S.
Federal or state or other applicable law. To effectuate the foregoing intention, each Holder and each Guarantor hereby irrevocably agree that the obligations of a Guarantor under its Note Guarantee shall be limited to the maximum amount as will,
after giving effect to all other contingent and fixed liabilities of such Guarantor result in the obligations of such Guarantor not constituting such a fraudulent transfer or conveyance.

 In case by reason of the suspension of regular mail service, or by reason of any other cause, it shall be impossible to mail

 SECTION 11.08. Governing Law.

Issuer, the Guarantors and the Trustee. This is one of an issue of Notes of the Issuer issued, or to be issued, under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to
the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb), as amended from time to time. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of them. Capitalized and
certain other terms used herein and not otherwise defined have the meanings set forth in the Indenture. To the extent any provision of the Indenture conflicts with any provision of this Note, the provision of the Indenture shall govern. 

5. Optional Redemption. 

(a) At any time prior to May 15, 2018, Quintiles may on any one or more occasions redeem up to 40% of the aggregate principal amount of

(2) the redemption occurs within 180 days of the date of the closing of such Equity Offering. 

(b) At any time prior to May 15, 2018, Quintiles may redeem all or any part of the Notes at a redemption price equal to 100% of the
principal amount thereof, plus the Applicable Redemption Premium and accrued and unpaid interest to (but not including) the Redemption Date. The Issuer shall notify the Trustee of the Applicable Redemption Premium by delivering to the Trustee, on or
before the applicable Redemption Date, an Officer’s Certificate showing the calculation thereof in reasonable detail, and the Trustee shall have no responsibility for such calculation. 

(c) Except pursuant to the preceding two paragraphs, the Notes will not be redeemable at Quintiles’ option prior to May 15, 2018. On
or after May 15, 2018, Quintiles may redeem all or any part of the Notes at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if any, on the Notes redeemed, to (but not
including) the applicable Redemption Date, if redeemed during the twelve-month period beginning on May 15 of the years indicated below:

 7. Notice of
Redemption. Notices of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address. If any Note is to be redeemed in part only,
the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. Any notice of any redemption may, at Quintiles’ discretion, be subject to one or more conditions precedent, including,
but not limited to, completion of a public or private offering for cash by Quintiles of its common stock or other corporate transaction. 

8. Offer To Purchase. The Indenture provides that upon the occurrence of a Change of Control Triggering Event and subject to further

 A-1-5 








 9. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in
denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes only in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements
and transfer documents and to pay to it any taxes and fees required by law or permitted by the Indenture. Neither the Registrar nor the Issuer shall be required to register the transfer of or exchange any Note or portion of a Note selected for
redemption (except the unredeemed portion of any Note redeemed in part), or register the transfer of or exchange any Note during the period beginning at the opening of business 15 days immediately preceding a mailing of notice of redemption and
ending at the close of business on the day of such mailing. 
 10. Persons Deemed Owners. The registered Holder of this Note may be
treated as the owner of this Note for all purposes. 
 11. Unclaimed Money. If money for the payment of principal or interest remains
unclaimed for two years, the Trustee will pay the money back to the Issuer at its written request. After that, Holders entitled to the money must look to the Issuer and the Guarantors for payment as general creditors unless an “abandoned
property” law designates another Person. 
 12. Amendment, Supplement, Waiver, Etc. The Issuer, the Guarantors, if applicable,
and the Trustee may, without the consent of the Holders of any outstanding Notes, amend, waive or supplement the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or inconsistencies,
maintaining the qualification of the Indenture under the TIA, providing for the assumption by a successor to the Issuer of its obligations to the Holders and making any change that does not adversely affect the Indenture rights of any Holder in any
material respect. Other amendments and modifications of the Indenture or the Notes may be made by the Issuer and the Trustee with the consent of the Holders of at least a majority of the aggregate principal amount of the outstanding Notes, subject
to certain exceptions requiring the consent of the Holders of the particular Notes affected. 
 13. Restrictive Covenants. The
Indenture imposes certain limitations on the ability of the Issuer and the Guarantors, as applicable, to, among other things, create Liens, enter into Sale and Lease-Back Transactions or consolidate, merge or sell all or substantially all of the
assets of the Issuer or any Guarantor, and requires the Issuer to provide reports to Holders of the Notes. Such limitations are subject to a number of important qualifications and exceptions. Pursuant to Section 4.06 of the Indenture, the
Issuer must annually report to the Trustee on compliance with such limitations. 
 14. Successor Corporation. When a successor
corporation assumes all the obligations of its predecessor under the Notes and the Indenture and the transaction complies with the terms of Article Five of the Indenture, the predecessor corporation will, except as provided in Article Five, be
released from those obligations. 

  
 A-1-6 








 15. Defaults and Remedies. Events of Default are set forth in the Indenture. Upon the
occurrence of an Event of Default, the rights and obligations of the Issuer, the Guarantors, the Trustee and the Holders will be as set forth in the applicable provisions of the Indenture. 

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory to it
before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal of or interest on the Notes, including payments pursuant to a redemption or repurchase of the Notes under the
Indenture) if a Responsible Officer in good faith determines that withholding notice is in their interests. 
 16. Trustee Dealings with
the Issuer. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Issuer or its Affiliates, and may otherwise deal with the Issuer or its Affiliates, as if it were not Trustee.

 17. No Recourse Against Others. No director, officer, employee, incorporator or stockholder of Quintiles or any Guarantor, as
such, will have any liability for any obligations of Quintiles or the Guarantors under the Notes, this Indenture, the Note Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by
accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws. 

18. Discharge. The Issuer’s obligations pursuant to the Indenture will be discharged, except for obligations pursuant to certain
sections thereof, subject to the terms of the Indenture, upon the payment of all the Notes or upon the irrevocable deposit with the Trustee of cash in U.S. Dollars, U.S. Government Obligations or a combination thereof, in such amounts as will be
sufficient to pay when due principal of and interest on the Notes to maturity or redemption, as the case may be. 
 19. Guarantees.
From and after the Issue Date, the Notes will be entitled to the benefits of Note Guarantees made for the benefit of the Holders. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and
obligations thereunder of the Guarantors, the Trustee and the Holders.
