 (REVERSE OF NOTE) 

TEXAS INSTRUMENTS INCORPORATED 

0.875% Notes due 2017 
 1.
Interest. 
 Texas Instruments Incorporated (the “Issuer”) promises to pay interest on the principal amount of this Note at
the rate per annum described above. Cash interest on the Notes will accrue from the most recent date to which interest has been paid; or, if no interest has been paid, from March 12, 2014. Interest on this Note will be paid to but excluding the
relevant Interest Payment Date. The Issuer will pay interest semi-annually in arrears on each Interest Payment Date, commencing September 12, 2014 to the person in whose name the Note is registered at the close of business on the preceding
Interest Record Date. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months in a manner consistent with Rule 11620(b) of the FINRA Uniform Practice Code. 

The Issuer shall pay interest on overdue principal from time to time on demand at the rate borne by the Notes and on overdue installments of
interest (without regard to any applicable grace periods) to the extent lawful. 
 2. Paying Agent. 

Initially, U.S. Bank National Association (the “Trustee”) will act as paying agent. The Issuer may change any paying
agent without notice to the Holders. 
 3. Indenture; Defined Terms. 

This Note is one of the 0.875% Notes due 2017 (the “Notes”) issued under an indenture dated as of May 23, 2011
(the “Base Indenture”) by and between the Issuer and the Trustee, and established pursuant to an Officers’ Certificate dated March 12, 2014, issued pursuant to Section 2.01 and Section 2.03 thereof (together, the
“Indenture”). This Note is a “Security” and the Notes are “Securities” under the Indenture. 

For purposes of this Note, unless otherwise defined herein, capitalized terms herein are used as defined in 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.C. Sections 77aaa-77bbbb) (the “TIA”) as in effect on the date on which the Indenture was
qualified under the TIA. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and
this Note are inconsistent, the terms of the Indenture shall govern. 

 4. Denominations; Transfer; Exchange. 

The Notes are in registered form, without coupons, in denominations of $2,000 and multiples of $1,000 thereafter. A Holder shall register the
transfer or exchange of Notes in accordance with the Indenture. The Issuer may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable
in connection therewith as permitted by the Indenture. The Issuer need not issue, authenticate, register the transfer of or exchange any Notes or portions thereof for a period of fifteen (15) days before the mailing of a notice of redemption,
nor need the Issuer register the transfer or exchange of any Note selected for redemption in whole or in part. 
 5. Amendment; Supplement;
Waiver. 
 Subject to certain exceptions, the Notes and the provisions of the Indenture relating to the Notes may be amended or supplemented
and any existing default or Event of Default or compliance with certain provisions may be waived with the written consent of the Holders of at least a majority in aggregate principal amount of all series of Outstanding Securities (including the
Notes) under the Indenture that are affected by such amendment, supplement or waiver (voting together as a single class). Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Notes to, among
other things, cure any ambiguity, omission, defect or inconsistency or comply with any requirements of the Commission in connection with the qualification of the Indenture under the TIA, or make any other change that does not adversely affect the
rights of any Holder of a Note in any material respect. 
 6. Redemption. 

The Issuer may at its option redeem any of the Notes in whole or in part at any time, each at a redemption price calculated by the Issuer equal
to the greater of: 
 (i) 100% of the principal amount of the Notes to be redeemed; and 

(ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such
payments of interest accrued as of the date of redemption), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 5 basis points, 

plus in each case accrued interest thereon to the date of redemption. 

 Notwithstanding the foregoing, installments of interest on Notes that are due and payable on
interest payment dates falling on or prior to a redemption date will be payable on the interest payment date to the registered Holders as of the close of business on the relevant record date according to the Notes and the Indenture. 

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a
maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to
the remaining term of the Notes. 
 “Comparable Treasury Price” means, with respect to any redemption date,
(i) the average of three Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Quotation Agent obtains fewer than three such
Reference Treasury Dealer Quotations, the average of all such quotations, or (iii) if only one Reference Treasury Dealer Quotation is received, such quotation. 

“Quotation Agent” means the Reference Treasury Dealer appointed by the Issuer. 

“Reference Treasury Dealer” means (i) Citigroup Global Markets Inc., Merrill Lynch, Pierce, Fenner &
Smith Incorporated and Mizuho Securities USA Inc. (or their respective affiliates that are Primary Treasury Dealers) and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary
U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Issuer will substitute therefor another Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer selected by the Issuer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date,
the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury
Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date. 
 “Treasury
Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of
its principal amount) equal to the Comparable Treasury Price for such redemption date. 

 Notice of any redemption will be mailed at least 30 days but not more than 60 days before the
redemption date to each Holder of the Notes to be redeemed. Unless the Issuer defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption. If
less than all of the Notes are to be redeemed, the Notes to be redeemed shall be selected by lot by the Depositary, in the case of Notes represented by a Global Note, or by the Trustee by a method the Trustee deems to be fair and appropriate, in the
case of Notes that are not represented by a Global Note. 
 7. Defaults and Remedies. 

If an Event of Default (other than certain bankruptcy Events of Default with respect to the Issuer) under the Indenture occurs with respect to
the Notes and is continuing, then the Trustee may and, at the direction of the Holders of at least 25% in principal amount of the outstanding Notes, shall by written notice, require the Issuer to repay immediately the entire principal amount of the
Outstanding Notes, together with all accrued and unpaid interest and premium, if any. If a bankruptcy Event of Default with respect to the Issuer occurs and is continuing, then the entire principal amount of the Outstanding Notes will automatically
become due immediately and payable without any declaration or other act on the part of the Trustee or any Holder. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to
enforce the Indenture or the Notes unless it has received indemnity as it reasonably requires. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding
to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of certain continuing defaults or Events of Default if it determines that withholding notice is in their interest. 

8. Authentication. 
 This Note
shall not be valid until the Trustee manually signs the certificate of authentication on this Note. 
 9. Abbreviations and Defined Terms.

 Customary abbreviations may be used in the name of a Holder of a Note or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

 10. CUSIP Numbers. 

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to
be printed on the Notes as a convenience to the Holders of the Notes. No representation is made as to the accuracy of such numbers as printed on the Notes and reliance may be placed only on the other identification numbers printed hereon 

11. Governing Law. 
 The laws of
the State of New York shall govern the Indenture and this Note thereof.

maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to
the remaining term of the Notes. 
 “Comparable Treasury Price” means, with respect to any redemption date,
(i) the average of three Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Quotation Agent obtains fewer than three such
Reference Treasury Dealer Quotations, the average of all such quotations, or (iii) if only one Reference Treasury Dealer Quotation is received, such quotation. 

“Quotation Agent” means the Reference Treasury Dealer appointed by the Issuer. 

“Reference Treasury Dealer” means (i) Citigroup Global Markets Inc., Merrill Lynch, Pierce, Fenner &
Smith Incorporated and Mizuho Securities USA Inc. (or their respective affiliates that are Primary Treasury Dealers) and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary
U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Issuer will substitute therefor another Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer selected by the Issuer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date,
the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury
Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date. 
 “Treasury
Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of
its principal amount) equal to the Comparable Treasury Price for such redemption date. 

 Notice of any redemption will be mailed at least 30 days but not more than 60 days before the
redemption date to each Holder of the Notes to be redeemed. Unless the Issuer defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption. If
less than all of the Notes are to be redeemed, the Notes to be redeemed shall be selected by lot by the Depositary, in the case of Notes represented by a Global Note, or by the Trustee by a method the Trustee deems to be fair and appropriate, in the
case of Notes that are not represented by a Global Note. 
 7. Defaults and Remedies. 

If an Event of Default (other than certain bankruptcy Events of Default with respect to the Issuer) under the Indenture occurs with respect to
the Notes and is continuing, then the Trustee may and, at the direction of the Holders of at least 25% in principal amount of the outstanding Notes, shall by written notice, require the Issuer to repay immediately the entire principal amount of the
Outstanding Notes, together with all accrued and unpaid interest and premium, if any. If a bankruptcy Event of Default with respect to the Issuer occurs and is continuing, then the entire principal amount of the Outstanding Notes will automatically
become due immediately and payable without any declaration or other act on the part of the Trustee or any Holder. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to
enforce the Indenture or the Notes unless it has received indemnity as it reasonably requires. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding
to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of certain continuing defaults or Events of Default if it determines that withholding notice is in their interest. 

8. Authentication.

 10. CUSIP Numbers. 

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to

provided, however, that a downgrade of the Notes by the applicable Rating Agency shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a downgrade for purposes of the definition
of Change of Control Triggering Event) if such Rating Agency making the reduction in rating does not publicly announce or confirm or inform the Company or the Trustee in writing at the request of the Company 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). Notwithstanding anything to
the contrary, no Change of Control Triggering Event shall be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

 -5- 

 “Consolidated Net Income” means, with respect to any specified Person for

period or any later period to the extent of any cash dividends or advances actually paid in the relevant period to such parent or any wholly-owned Subsidiary of such parent). 

“Consolidated Net Tangible Assets” means, with respect to any specified Person as of any date, the total assets of
such Person and its Subsidiaries as of the most recent fiscal quarter end for which a consolidated balance sheet of such Person and its Subsidiaries is available as of that date, minus (a) all current liabilities of such
Person and its Subsidiaries reflected on such balance sheet (excluding any revolving loans pursuant to the Company’s Senior Secured Credit Facility and current liabilities for borrowed money having a maturity of less than 12 months but by its

its Subsidiaries reflected on such balance sheet, as determined on a consolidated basis in accordance with GAAP. 

“Consolidated Secured Indebtedness” means, with respect to any specified Person as of any date, (a) the total

Indebtedness outstanding and any that may be borrowed pursuant to commitments under the Senior Secured Credit Facility as contemplated under the last paragraph of the definition of “Permitted Liens” in this Section 1.02. 

“Consolidated Secured Leverage Ratio” means, with respect to any specified Person as of any date, the ratio of
(a) the Consolidated Secured Indebtedness of such Person as of such date to (b) the Consolidated EBITDA of such Person for the four most recent full fiscal quarters ending immediately prior to such date for which internal financial
statements are available. In the event that the specified Person or any of its Subsidiaries incurs, assumes, guarantees, repays, repurchases, redeems, defeases or otherwise discharges any Indebtedness that is secured by a Lien on Principal Property
of such Person or upon Capital Stock or Indebtedness of any of its Subsidiaries (other than ordinary working capital borrowings) subsequent to the commencement of the period for which such Consolidated EBITDA is being calculated and on or prior to
the date on which the event for which the calculation of the Consolidated Secured Leverage Ratio is made (the “Calculation Date”), then the Consolidated Secured Leverage Ratio shall be calculated giving pro forma effect to such
incurrence, assumption, guarantee, repayment, repurchase, redemption, defeasance or other discharge of Indebtedness, and the use of the proceeds therefrom, as if the same had occurred at the beginning of the applicable four-quarter reference period.
In addition, for purposes of calculating the Consolidated Secured Leverage Ratio: 

  
 -6- 

 (1) acquisitions and dispositions that have been made by the specified Person or
any of its Subsidiaries, including through mergers or consolidations, or any Person or any of its Subsidiaries acquired by the specified Person or any of its Subsidiaries, and including any related financing transactions and giving effect to the
application of proceeds from any dispositions, during the four-quarter reference period or subsequent to such reference period and on or prior to the Calculation Date shall be deemed to have occurred on the first day of the four-quarter reference
period; and 
 (2) the Consolidated EBITDA attributable to discontinued operations, as determined in accordance with GAAP,
and operations or businesses disposed of prior to the Calculation Date, shall be excluded, 
 provided that to the extent that clause (1) or
(2) of this paragraph requires that pro forma effect be given to an acquisition, disposition or discontinued operations, as applicable, such pro forma calculation shall be made in good faith by a responsible financial or accounting officer of
the Company (and may include, for the avoidance of doubt and without duplication, cost savings, synergies, operating expense reductions and other operating improvements and initiatives resulting from such acquisition, disposition or discontinued
operations whether or not such cost savings, synergies, operating expense reductions or other operating improvements and initiatives would be allowed under Regulation S-X promulgated by the Commission or any other regulation or policy of the

 The Company may, without the

 The form of Note and the Trustee’s

and interest on the Notes to be redeemed (exclusive of interest accrued to the applicable Redemption Date) discounted to such Redemption Date on a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at the then current
Treasury Rate plus 50 basis points, 
 plus, in each case, accrued and unpaid interest thereon to, but not including, the applicable Redemption Date;

the Person in whose name the Note is registered at the close of business on the corresponding Record Date (instead of the Holder surrendering its Notes for redemption). 

If the Company becomes obligated to pay, on the next date on which any amount shall be payable with respect to the Notes, any
Additional Amounts as a result of (i) any amendment to, or change in, the laws or regulations of a Relevant Taxing Jurisdiction which amendment or change is publicly announced and becomes effective after the Issue Date (or, if the applicable
Relevant Taxing Jurisdiction became a Relevant Taxing Jurisdiction on a date after the Issue Date, after such later date) or (ii) any amendment to, or change in, an official written interpretation or application of such laws or regulations

Jurisdiction on a date after the Issue Date, after such later date) (each of the foregoing clauses (i) and (ii), a “Change in Tax Law”) and the Company cannot avoid any such payment obligation by taking reasonable measures
available to it (including making payment through a paying agent located in another jurisdiction, but not including the substitution of an obligor), the Company may, at its option, redeem the Notes then outstanding, in whole but not in part, at a
redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the Redemption Date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest
Payment Date falling on or prior to the Redemption Date). Notice of the Company’s intent to redeem the Notes shall not be given until the Company delivers to the Trustee an opinion of independent tax counsel of recognized standing to the effect
that there has been such Change in Tax Law which would entitle the Company to redeem the Notes hereunder and an Officers’ Certificate to the effect that the Company cannot avoid its obligation to pay Additional Amounts by taking reasonable
measures available to it. The foregoing provisions shall apply mutatis mutandis to any successor Person to the Company, after such successor Person becomes a party to the Indenture, with respect to a Change in Tax Law that is
publicly announced and becomes effective after such successor Person becomes a party to the Indenture. 
 The Company shall give not
less than 30 nor more than 60 days’ prior written notice mailed by first-class mail to the registered address of each Holder or otherwise in accordance with the procedures of the Depository of any redemption; provided that the notice
pursuant to the previous paragraph shall not be provided (i) earlier than 90 days before the next date on which the Company would be obligated to pay Additional Amounts and (ii) unless at the time such notice is given, such obligation to
pay such Additional Amounts remains in effect.

hereof, if the aggregate outstanding principal amount of all Indebtedness of the Company and its Subsidiaries that is subject to and not otherwise permitted under Sections 4.02 and 4.03 hereof does not exceed the greater of
(a) $100 million and (b) 15% of the Consolidated Net Tangible Assets of the Company and its Subsidiaries (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, based on the consolidated balance sheet of the Company and its Subsidiaries for the end of the then most recent quarter for which financial statements are available), then: 

(i) the Company or any of its Subsidiaries may incur or guarantee Indebtedness secured by Liens upon any Principal Property,
Capital Stock or Indebtedness; 
 (ii) the Company or any of its Subsidiaries may enter into any Sale and Lease-Back
Transaction; and 
 (iii) the Company may guarantee the obligations of any of its Subsidiaries under clauses (i) and

 -17- 

 SECTION 4.05 Future Guarantors. The Company shall cause each of its Subsidiaries that
guarantees, on the Issue Date or any time hereafter, any Funded Debt (including commitments in respect thereof in case of a revolving credit facility) of the Company or any Guarantor in an amount in excess of $175.0 million aggregate principal
amount to execute and deliver to the Trustee substantially concurrently therewith a supplemental indenture pursuant to which such Subsidiary shall unconditionally Guarantee, on a joint and several basis, the full and prompt payment of the principal
of, premium, if any, and interest in respect of the Notes on a senior basis and all other Company obligations under the Indenture. 

SECTION 4.06 Covenant Suspension. (a) If on any date following the Issue Date (i) the Notes have Investment Grade Ratings
from both Rating Agencies and (ii) no Default has occurred and is continuing under the Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant
Suspension Event”), the Company and its Subsidiaries shall not be subject to Section 4.01 hereof (the “Suspended Covenant”). 

(b) In the event that the Company and its Subsidiaries are not subject to the Suspended Covenant under this Supplemental Indenture for any
period of time pursuant to Section 4.06(a) hereof, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies (i) withdraw their Investment Grade Rating or downgrade the rating assigned to
the Notes below an Investment Grade Rating and/or (ii) the Company or any of its Affiliates enters into an agreement to effect a transaction that would result in a Change of Control Triggering Event and one or more of the Rating Agencies
indicate that if consummated, such transaction (alone or together with any related recapitalization or refinancing transactions) would cause such Rating Agency to withdraw its Investment Grade Rating or downgrade the ratings assigned to the Notes
below an Investment Grade Rating, then the Company and its Subsidiaries shall thereafter again be subject to the Suspended Covenant under this Supplemental Indenture with respect to future events, including a proposed transaction described in clause
(ii) of this Section 4.06(b). 
 (c) The period of time between the Covenant Suspension Event and the Reversion Date is
referred to in this description as the “Suspension Period.” In the event of any such reinstatement, no action taken or omitted to be taken by the Company or any of its Subsidiaries prior to such reinstatement shall give rise to a
Default or Event of Default under the Indenture with respect to Notes.

Officers’ Certificate notifying it of any Covenant Suspension Event or Reversion Date. The Trustee will have no obligation to (i) independently determine or verify if a Suspension Period has begun or ended, (ii) make any determination
regarding the impact of actions taken during the Suspension Period on the Company’s future compliance with its covenants or (iii) inform the Holders of the occurrence of a Covenant Suspension Event or Reversion Date. 

SECTION 4.07 Commission Reports. Clause (1) of Section 4.04 of the Original Indenture is hereby amended and restated solely
with respect to the Notes (and any Additional Notes), but not with respect to any other series of Securities under the Indenture as follows: 

“(1) deliver to the Trustee and each Holder, within 15 days after the Company is required to file the same with the Commission, copies of
all reports and other information (or copies of such portions of any of the foregoing as the Commission may by rules and regulations prescribe), if any, which the Company is required to file with the Commission pursuant to Section 13 or 15(d)
of the Exchange Act. If the Company is not subject to the requirements of Section 13 or 15(d) of the Exchange Act, the Company shall deliver to the Trustee and to each Holder, within 15 days after the Company would have been required to file
such reports and other information with the Commission were the Company required to do so, financial statements, including any notes thereto (and, in the case of a fiscal year end, an auditors’ report by an independent certified public
accounting firm of established national 

  
 -18- 

 
reputation), and a “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” substantially equivalent to that which the Company would have been
required to include in such quarterly or annual reports, information, documents or other reports if the Company had been subject to the requirements of Section 13 or 15(d) of the Exchange Act.” 

SECTION 4.08 Compliance Certificates. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the
Company an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Officers of the Company they would normally have knowledge of any Default and whether or not the signers know of any Default that
occurred during such period. If they do, the certificate shall describe the Default, its status and what action the Company is taking or proposes to take with respect thereto. 

SECTION 4.09 Payment of Additional Amounts. (a) All payments made by or on behalf of the Company under or with respect to the
Notes, or by or on behalf of any Guarantor under or with respect to any Guarantee (each such Person, a “Payor”) shall be made free and clear of any withholding or deduction for or on account of any tax, duty, levy, impost,
assessment or other governmental charge of whatever nature, including any related interest, penalties or additions to tax (collectively, “Tax”) imposed or levied by or on behalf of any jurisdiction in which any Payor is organized,
resident or doing business for tax purposes or from or through which any Payor or its agents makes any payment under or with respect to any Notes or Guarantee or any department or political subdivision of any of the foregoing (each, a
“Relevant Taxing Jurisdiction”), unless an applicable withholding agent is required to withhold or deduct any such Taxes by law or by the interpretation or administration thereof by the relevant government authority or agency. If an
applicable withholding agent is so required to withhold or deduct any amount for or on account of any Taxes of a Relevant Taxing Jurisdiction in respect of any payment under or with respect to any Notes or Guarantee, the Payor, subject to the
exceptions listed below, shall pay additional amounts (“Additional Amounts”) as may be necessary to ensure that the net amount received by each beneficial owner of the Notes after such withholding or deduction (including withholding
or deduction attributable to Additional Amounts payable hereunder) shall not be less than the amount the beneficial owner would have received if such Taxes had not been withheld or deducted. 

(b) A Payor shall not, however, be required to pay any Additional Amounts: 

(i) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the existence of any
present or former connection between the Holder or beneficial owner (or between a fiduciary, settler, beneficiary, member or shareholder of, or possessor of a power over, such Holder or beneficial owner, if such Holder or beneficial owner is an
estate, trust, partnership or corporation) and the Relevant Taxing Jurisdiction (other than any connection resulting solely from the acquisition, ownership, holding or disposition of Notes, the receipt of payments thereunder or under any Guarantee
and/or the exercise or enforcement of rights under any Notes or any Guarantee); 
 (ii) to the extent the Taxes giving rise
to such Additional Amounts would not have been imposed but for the failure of the Holder or beneficial owner of Notes, following the Company’s or the Payor’s written request addressed to the Holder, to the extent such Holder or beneficial
owner is legally eligible to do so, to comply with any certification, identification, information or other reporting requirements, whether required by statute, treaty, regulation or administrative practice of a Relevant Taxing Jurisdiction, as a
precondition to exemption from, or reduction in the rate of deduction or withholding of, Taxes imposed by the Relevant Taxing Jurisdiction (including a certification that the Holder or beneficial owner is not resident in the Relevant Taxing
Jurisdiction); 

  
 -19- 

 (iii) with respect to any estate, inheritance, gift, sales or any similar Taxes;

 (iv) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the presentation
by the Holder or beneficial owner of any Notes, where presentation is required, for payment more than 30 days after the date on which payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;

 (v) to the extent any Canadian Taxes giving rise to such Additional Amounts would not have been imposed but for the Holder
or beneficial owner not dealing at arm’s length, within the meaning of the Income Tax Act (Canada), with the Company or such Payor; 

(vi) to the extent any Canadian Taxes giving rise to such Additional Amounts would not have been imposed but for such Holder or
beneficial owner being, or not dealing at arm’s length (within the meaning of the Income Tax Act (Canada)) with, a “specified shareholder” of the Company as defined in subsection 18(5) of the Income Tax Act (Canada) for purposes of
the thin capitalization rules in the Income Tax Act (Canada); or 
 (vii) any combination of clauses (i), (ii), (iii), (iv),
(v), or (vi) above. 
 (c) The applicable withholding agent shall (i) make any such required withholding or deduction and
(ii) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. A Payor, if it is the applicable withholding agent, shall make reasonable efforts to obtain certified copies of tax receipts evidencing
the payment of any Taxes so deducted or withheld from each Relevant Taxing Jurisdiction imposing such Taxes. The Company, if any Payor is the applicable withholding agent, shall provide to the Trustee, within a reasonable time after the date the
payment of any Taxes so deducted or withheld are due pursuant to applicable law, either a certified copy or tax receipts evidencing such payment, or, if such tax receipts are not reasonably available to the Company, such other documentation that
provides reasonable evidence of such payment by the applicable Payor. 
 (d) Where Tax is payable under Part XIII of the Income Tax Act
(Canada) by a Holder or beneficial owner of Notes by reason of Regulation 803 of the Income Tax Regulations (Canada) promulgated under the Income Tax Act (Canada) or any similar provision (other than by reason of a transfer of the Notes to a Person
resident in Canada with whom the transferor does not deal at arm’s length for the purposes of the Income Tax Act (Canada)), but the applicable Payor is not required to withhold or deduct an amount in respect of such Tax, the Payors shall pay to
the Holder or beneficial owner such Additional Amounts as may be necessary in order that the amount received by each affected Holder or beneficial owner of the Notes net of such Tax shall equal the amount such Holder or beneficial owner of the Notes
would have received in respect of such payments in the absence of such Tax, provided such Holder or beneficial owner would otherwise have been entitled to receive Additional Amounts on account of such Tax (having regard to clauses (a)(i) to (a)(vii)
of this Section 4.09) and in any event only to the extent of such Additional Amounts that such Holder or beneficial owner would otherwise have been entitled to receive had the applicable Payor been required to withhold or deduct an
amount in respect of such Tax. 
 (e) If any Additional Amounts become payable, the Company shall deliver to the Trustee an Officers’
Certificate stating that such Additional Amounts shall be payable prior to the date on which such payments shall be made, and the amounts so payable, and shall set forth such other information necessary to enable the Trustee, upon receipt of funds
from the Company, to pay such Additional Amounts to Holders on the payment date. Any such Officers’ Certificate shall be delivered at least three (3) Business Days in advance of when the payments in question are required to be made. The
Company shall promptly deliver a notice to the Trustee and the Holders in accordance with the provisions of the Indenture stating that such Additional Amounts shall be payable and describing the obligation to pay such amounts. 

  
 -20- 

 (f) In addition, the Company shall pay any stamp, issue, registration, court, documentary, excise
or other similar taxes, charges and duties, including interest, additions to tax and penalties with respect thereto, imposed by any Relevant Taxing Jurisdiction at any time in respect of the execution, issuance, registration or delivery of the Notes
or any Guarantee or any other document or instrument referred to thereunder and any such taxes, charges or duties imposed by any Relevant Taxing Jurisdiction at any time as a result of, or in connection with, (i) any payments under or with
respect to the Notes or any Guarantee or any other such document or instrument referred to thereunder and/or (ii) the enforcement of the Notes or any Guarantee or any other such document or instrument referred to thereunder. 

(g) The obligations pursuant to this Section 4.09 shall survive any termination, defeasance or discharge of the Indenture and shall
apply mutatis mutandis to any successor Person to any Payor and to any jurisdiction in which any successor is organized, doing business or is otherwise resident for tax purposes or any jurisdiction from or through which payment is made by any
successor or its respective agents. Whenever the Indenture refers to, in any context, the payment of principal, premium, if any, interest or any other amount payable under or with respect to any Note or under any Guarantee, such reference includes
the payment of Additional Amounts as described hereunder, if applicable.

against the Company or any Guarantor for any U.S. dollar amount due under this Supplemental Indenture and such judgment or order being expressed and paid in a currency (the “Judgment Currency”) other than U.S. dollars and as a
result of any variation as between (i) the rate of exchange at which the U.S. dollar amount is converted into the Judgment Currency for the purpose of such judgment or order and (ii) the spot rate of exchange in The City of New York at
which such party on the date of payment of such judgment or order is able to purchase U.S. dollars with the amount of the Judgment Currency actually received by such party if such party had utilized such amount of Judgment Currency to purchase U.S.
dollars upon such party’s receipt thereof. The foregoing indemnity shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “spot rate of exchange” shall include any premiums and costs
of exchange payable in connection with the purchase of, or conversion into, U.S. dollars. 
 SECTION 8.10 Usury Savings Clause. If
any provision of this Supplemental Indenture or any Note would obligate the Company to make any payment of or on account of interest or other amount in an amount or calculated at a rate which would result in a receipt by any Holder of interest at a
criminal rate (as such term is construed under the Criminal Code (Canada)), then notwithstanding such provisions, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the
case may be, as would not so result in a receipt by such Holder of interest at a criminal rate, such adjustment to be effected, to the extent necessary, as follows: (1) firstly, by reducing the amount or rate of interest required to be paid to
such Holder, and (2) thereafter, by reducing any fees, commissions, premiums and other amounts required to be paid to such Holder which would constitute “interest” for purposes of Section 347 of the Criminal Code (Canada).

 [FORM OF REVERSE OF NOTE] 

Catamaran Corporation 

4.75% SENIOR NOTES DUE 2021 

1. Interest. Catamaran Corporation, a corporation duly organized and existing under the laws of the Yukon Territory, Canada, as issuer
(the “Company”), promises to pay, until the principal hereof is paid or made available for payment, interest on the principal amount set forth on the face hereof at a rate of 4.75% per annum. Interest hereon will accrue from
and including the most recent date to which interest has been paid or, if no interest has been paid, from and including the date of issuance to but excluding the date on which interest is paid. Interest shall be payable in arrears on each
March 15 and September 15, commencing September 15, 2014. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. The Company shall pay interest on overdue principal and on overdue interest (to the
full extent permitted by law) at the rate borne by the Notes. 
 2. Method of Payment. The Company will pay interest hereon (except
defaulted interest) to the Persons who are registered Holders at the close of business on March 1 and September 1 immediately preceding the Interest Payment Date (whether or not a Business Day). Holders must surrender Notes to a Paying
Agent to collect principal payments. The Company will pay to the Paying Agent principal and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. If a Holder has given
wire transfer instructions to the Company, the Company may pay, or cause to be paid by the Paying Agent, all principal, interest on that Holder’s Notes in accordance with those instructions. All other payments on the Notes will be made at the
Place of Payment unless the Company elects to make interest payments by check mailed to the Holders at their address set forth in the register of Holders. 

3. Paying Agent and Registrar. Initially, Wilmington Trust, National Association (the “Trustee”) will act as a Paying
Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to the Holders. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. 

4. Indenture. This Note is on the series designated on the face hereof initially limited in aggregate principal amount to $500,000,000.
This Note is one of a duly authorized issue of securities of the Company issued and to be issued in one or more series under an Indenture dated as of March 6, 2014 (the “Original Indenture”, which term shall have the meaning
assigned to it in such instrument) between the Company and the Trustee, as supplemented by the Supplemental Indenture dated as of March 12, 2014 (the “Supplemental Indenture” and the Original Indenture, as supplemented by the
Supplemental Indenture, 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 “Trust Indenture Act”). The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture 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. 
 The Company may, without the consent of the Holders
of the Notes, hereafter issue additional Notes (“Additional Notes”) under the Indenture with the same terms and with the same CUSIP numbers as the Notes issued on the date of the Supplemental Indenture (the “Initial
Notes”) in an unlimited aggregate principal amount; provided that such Additional Notes must be part of the same issue as the Initial Notes for federal income tax purposes. Any such Additional Notes shall constitute a
single series together with the Initial Notes for all purposes hereunder, including waivers, amendments and offers to purchase, provided that if any such Additional Notes are not fungible with the Initial Notes for U.S. federal income tax purposes,
such Additional Notes shall have a separate CUSIP number. 

 5. Optional Redemption. The Company may redeem the Notes in accordance with Article Three
of the Original Indenture, in whole or in part, at any time prior to the scheduled maturity of the Notes, at a redemption price equal to the greater of: 

(a) 100% of the principal amount of the Notes to be redeemed; and 

(b) the sum of the present values of the remaining scheduled payments of principal of and interest on the Notes to be redeemed
(exclusive of interest accrued to the applicable redemption date (the “Redemption Date”)) discounted to such Redemption Date on a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at the then current
Treasury Rate plus 50 basis points, 
 plus, in each case, accrued and unpaid interest thereon to, but not including, the applicable Redemption Date;
provided, however, that if the Redemption Date falls on or after the interest Record Date and on or prior to the related Interest Payment Date, the Company shall pay the full amount of accrued and unpaid interest, if any, on such Redemption Date to
the Person in whose name the Note is registered at the close of business on the corresponding Record Date (instead of the Holder surrendering its Notes for redemption). 

Notices of purchase or redemption shall be given by first-class mail, postage prepaid, at least 30 but not more than 60 days before the
purchase or Redemption Date to each Holder of Notes at such Holder’s registered address or otherwise in accordance with the procedures of the Depository, except that redemption notices may be given more than 60 days prior to a Redemption Date
if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. If any Note is to be purchased or redeemed in part only, any notice of purchase or redemption that relates to such Note shall
state the portion of the principal amount thereof that has been or is to be purchased or redeemed. 
 Any notice of any redemption may, at
the Company’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 Company of its common stock or other corporate transaction. 

Pursuant to Section 4.09 of the Supplemental Indenture, the Company may be required to pay Additional Amounts with respect to the
Notes or the Company may, at its option, redeem the Notes then outstanding, in whole but not in part, at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the Redemption Date (subject to
the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date falling on or prior to the Redemption Date) subject to the terms and conditions of Section 4.09 of the Supplemental
Indenture. 
 6. Denominations, Transfer, Exchange. The Notes are in registered form without coupons and in minimum denominations of
$2,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes 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 the Indenture. 
 7. Persons Deemed Owners. The registered Holder of this Note
may be treated as the owner of this Note for all purposes. 
 8. Unclaimed Money. If money for the payment of principal or interest
remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an “abandoned
property” law designates another Person. 

 9. Amendment, Waiver, Etc. The Company and the Trustee (if a party thereto) may, without
the consent of the Holders of any outstanding Notes, amend or waive 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 Trust Indenture Act, as amended, and providing for the assumption by a successor to the Company of its obligations under the Indenture. Other amendments of the Indenture or the Notes may be made by the Company and the Trustee
with the consent of the Holders of Notes representing not less than a majority of the aggregate principal amount of the outstanding Notes (including any Additional Notes) (including consents obtained in connection with a purchase of, or tender offer
or exchange offer for, the Notes), subject to certain exceptions requiring the consent of all Holders of the Notes. 
 10. 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 Section 5.01 of the Original Indenture, the predecessor
corporation will, except as provided in Section 5.01 of the Original Indenture, be released from those obligations. 
 11.
Defaults and Remedies. Events of Default are set forth in the Indenture. Subject to certain limitations in the Indenture, if an Event of Default (other than an Event of Default specified in Sections 6.01(4) and 6.01(5) of the
Original Indenture) with respect to the Notes occurs and is continuing, then, and in each and every such case, either the Trustee, by notice in writing to the Company, or the Holders of not less than 25% of the principal amount of the Notes then
outstanding, by notice in writing to the Company and the Trustee, may declare due and payable, if not already due and payable, the principal of and any accrued and unpaid interest on all of the Notes; and upon any such declaration all such amounts
upon such Notes shall become and be immediately due and payable, anything in the Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Sections 6.01(4) and 6.01(5) of the Original Indenture
occurs, then the principal of and any accrued and unpaid interest on all of the Notes shall immediately become due and payable without any declaration or other act on the part of the Trustee or any Holder. 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 (except a default in payment of principal, premium, if any, or interest on the Notes) if it determines that
withholding notice is in their interests. 
 12. Trustee Dealings with Company. Subject to certain limitations imposed by the Trust
Indenture Act, the Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not
Trustee. 
 13. No Recourse Against Others. No past, present or future director, officer, employee, incorporator, agent, member or
stockholder or Affiliate of the Company, as such, shall have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder
of Notes by accepting a Note waives and releases all such liabilities. The waiver and release are part of the consideration for issuance of the Notes. 

 14. Discharge; Defeasance. The Company’s and each Guarantor’s, if any,
obligations pursuant to the Indenture with respect to Notes will be discharged, except for obligations pursuant to certain sections thereof, subject to the terms of the Indenture. 

The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness of the Company and the Guarantors, if any, on
this Note and (b) certain restrictive covenants and the related Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note. 

15. Authentication. This Note shall not be valid until the Trustee signs the certificate of authentication on the other side of this
Note. 
 16. Governing Law. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. 

17. Guarantee. As more fully set forth in the Indenture, the Company’s obligations under the Notes shall be guaranteed, to the
extent permitted by law, by each Guarantor. Any such Guarantee may be terminated or released in accordance with the provisions of the Indenture. 

18. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common),
TENANT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).
