The Issuer

Overview

Colombia is the fourth largest country in South America, with a territory of 441,020 square miles (1,141,748 square kilometers). Located on the northwestern corner of the South American continent, Colombia borders Panama and the Caribbean Sea on the north, Peru and Ecuador on the south, Venezuela and Brazil on the east and the Pacific Ocean on the west. According to the Departamento Administrativo Nacional de Estadística (National Administrative Department of Statistics, or “DANE”) based on the latest available population statistics, Colombia’s population was 52.2 million in 2023. The latest available population statistics also estimated 7.9 million people live in Bogotá, the capital of Colombia. Furthermore, in 2023, Medellín and Cali, the second and third largest cities, are estimated to have populations of approximately 2.6 million and 2.3 million, respectively. Of the total population, 76.1% live in populated municipal centers and 23.9% in dispersed rural areas.

Government

Colombia is governed as a Presidential Republic. Colombia’s territory is divided into 32 departments. Each department is divided into municipalities.

The Republic of Colombia is one of the oldest democracies in the Americas. In 1991, a popularly elected Constitutional Assembly approved a new Constitution, replacing the Constitution of 1886. The Constitution provides for three independent branches of government: an executive branch headed by the President; a legislative branch consisting of the bicameral Congress, composed of the Chamber of Representatives and the Senate; and a judicial branch consisting of the Corte Constitucional (Constitutional Court), the Corte Suprema de Justicia (Supreme Court of Justice, or “Supreme Court”), the Consejo de Estado (Council of State), the Consejo Superior de la Judicatura (Supreme Judicial Council), the Fiscalía General de la Nación (National Prosecutor General) and in such lower courts as may be established by law.

In the most recent presidential elections that took place on May 29, 2022, Gustavo Petro of Pacto Histórico won the first ballot with 40.32% of the vote, while Rodolfo Hernández of Liga de Gobernantes Anticorrupción came in second with 28.15% of the vote. On June 19, 2022, Mr. Petro won the second ballot and was elected President of the Republic of Colombia with 50.44% of the vote. President Petro took his oath and assumed the office of the President on August 7, 2022. The next presidential election is scheduled for May 2026.

Judicial power is vested in the Constitutional Court, the Supreme Court, the Council of State, the Supreme Judicial Council, the National Prosecutor General and in such lower courts as may be established by law. The function of the Constitutional Court, whose nine members are elected by the Senate for an eight-year term, is to ensure that all laws are consistent with the Constitution and to review all decisions regarding fundamental rights. The Supreme Court is the final appellate court for resolving civil, criminal and labor proceedings. The Council of State adjudicates all matters relating to the exercise of public authority or actions taken by the public sector, including the review of all administrative decisions or resolutions that are alleged to contradict the Constitution or the law. The Council of State also acts as advisor to the Government on administrative matters. The Supreme

S-1

Court and Council of State justices are appointed for eight-year terms by their predecessors from a list of candidates provided by the Supreme Judicial Council. The National Prosecutor General, who is appointed for a four-year term by the Supreme Court from a list of three candidates submitted by the President, acts as the nation’s prosecutor. The judicial branch is independent from the executive branch with respect to judicial appointments as well as budgetary matters.

National legislative power is vested in the Congress, which consists of a 108-member Senate and a 172-member Chamber of Representatives. Senators and Representatives are elected by direct popular vote for terms of four years. Senators are elected on a nonterritorial basis, while Representatives are elected on the basis of proportional, territorial representation. In each department, administrative power is vested in departmental assemblies whose members are elected by direct popular vote. At the municipal level, administrative power is vested in municipal councils, which preside over budgetary and administrative matters.

The most recent Congressional elections occurred on March 13, 2022, and the new Congress will serve for a period of four years, beginning on July 20, 2022. The following table shows the composition of Congress by political party.

As a result of the peace agreements signed with the FARC party (Partido Político Comunes) and the related political reform approved in 2015, (i) the Partido Político Comunes was awarded five seats in the Senate and five seats in the Chamber of Representatives regardless of the vote obtained, and (ii) an additional seat was added in the Senate for the candidate who obtained the second highest vote in the presidential elections and an additional seat in the Chamber of Representatives was added for the losing vice presidential candidate. Additionally, through Legislative Act No. 2, dated August 25, 2021, 16 seats in the Chamber of Representatives were temporarily designated for candidates from the Special Constituencies for Peace (Circunscripciones para la Paz) for the 2022-2026 and 2026-2030 legislatures to represent victims of the armed conflict. For this reason, the Partido Político Comunes and Circunscripciones para la Paz seats have not been included in the table above. The final two seats are awarded to the losing president and vice presidential candidates.

RISK FACTORS

This section describes certain risks associated with investing in the bonds. You should consult your financial and legal advisors about the risk of investing in the bonds. Colombia disclaims any responsibility for advising you on these matters.

Risk Factors Relating to the Bonds

The price at which the bonds will trade in the secondary market is uncertain.

Colombia has been advised by the underwriters that they intend to make a market in the bonds but are not obligated to do so and may discontinue market making at any time without notice. Application will be made to list the bonds on the official list of the Luxembourg Stock Exchange and to trade them on the Euro MTF Market of the Luxembourg Stock Exchange. Application will also be made to the London Stock Exchange for the bonds to be admitted to trading on the London Stock Exchange’s ISM. The ISM is not a regulated market for the purposes of MiFID II. No assurance can be given as to the liquidity of the trading market for the bonds. The price at which the bonds will trade in the secondary market is uncertain.

The bonds will contain provisions that permit Colombia to amend the payment terms without the consent of all holders.

The bonds will contain provisions regarding acceleration and voting on amendments, modifications and waivers which are commonly referred to as “collective action clauses.” Under these provisions, certain key terms of the bonds may be amended, including the maturity date, interest rate and other payment terms, without your consent. See “Description of the Securities—Meetings and Amendments—Collective Action Clause” in the accompanying prospectus.

Risk Factors Relating to Colombia

Colombia is a foreign sovereign state and accordingly it may be difficult to obtain or enforce judgments against it.

Colombia is a foreign sovereign state. As a result, it may not be possible for investors to effect service of process within their own jurisdictions upon Colombia or to enforce against Colombia judgments obtained in their own jurisdictions. See “Description of the Securities—Jurisdiction; Enforceability of Judgments” in the accompanying prospectus.

Certain economic risks are inherent in any investment in an emerging market country such as Colombia.

Investing in an emerging market country such as Colombia carries economic risks. These risks include economic instability that may affect Colombia’s economic results. Economic instability in Colombia and in other Latin American and emerging market countries has been caused by many different factors, including the following:

• high interest rates;

• changes in currency values;

• changes in government revenue and spending trends;

• changes in commodity prices, such as a decline in oil prices;

• high levels of inflation;

• exchange controls;

• wage and price controls;

• changes in economic or tax policies;

• the imposition of trade barriers;

• internal security issues; and

• the public health crisis and economic shutdowns caused by the COVID-19 pandemic, any subsequent wave or resurgence and/or new pandemic.

Any of these factors, as well as volatility in the markets for securities similar to the bonds, may adversely affect the liquidity of, and trading markets for, the bonds. See “Forward-Looking Statements” in the accompanying prospectus. For further information on internal security, see “Recent Developments—Republic of Colombia”.

Colombia’s economy remains vulnerable to external shocks, including those that could be caused by future significant economic difficulties of its major regional trading partners or by more general “contagion” effects, which could have a material adverse effect on Colombia’s economic growth and its ability to service its public debt.

The mining sector (including oil) is a significant contributor to the Colombian economy and is a principal source of exports. Oil prices are volatile and a significant decrease in oil prices would have a negative impact on Colombia’s economy.

The United States, Panamá, the European Union and China are Colombia’s first, second, third and fourth most important trading partners in terms of exports, respectively. As of August, 2024, according to preliminary figures, exports to the United States, Panama, China and India, accounted for 29.1%, 9.1%, 5.5% and 5.6% of total exports, respectively, compared to the same period of 2023, during which exports to the United States, Panama, China and India, accounted for 26.8%, 8.6%, 4.8% and 4.2% of total exports, respectively. For more information, see “Recent Developments—Monetary System— Interest Rates and Inflation” and “ — Foreign Exchange Rates and International Reserves” in this prospectus supplement, and “Economy—Gross Domestic Product,” “Monetary System—Foreign Exchange Rates and International Reserves” and “ —Interest Rates and Inflation” in Colombia’s annual report on Form 18-K for the year ended December 31, 2023, filed with the SEC on September 13, 2024, (including all exhibits thereto), as amended from time to time (the “2023 Annual Report”).

Emerging-market investment generally poses a greater degree of risk than investment in more mature market economies because the economies in the developing world are more susceptible to destabilization resulting from domestic and international developments.

A significant decline in the economies of any of Colombia’s major trading partners, such as the United States, the European Union or China could have a material adverse impact on Colombia’s balance of trade and adversely affect Colombia’s economic growth. In 2023, the United States accounted for 29.1% of Colombia’s total exports, Panama accounted for 9.1% of Colombia’s total exports and China accounted for 5.5% of Colombia’s total exports. A decline in United States or European Union demand for imports could have a material adverse effect on Colombian exports and Colombia’s economic growth. Continued outbreaks due to COVID-19 or a future pandemic and economic shutdown to combat such outbreaks in the United States and Europe could have a material adverse impact on Colombia’s exports and economic growth.

S-10

The occurrence of unusual weather conditions, epidemic or pandemic outbreaks (such as COVID-19), terrorist attacks, disruptive political events, including sanctions, embargoes and asset freezes, civil unrest, actual or threatened acts of war, escalation of current hostilities in the Middle East and elsewhere, including the current conflict between Russia and Ukraine, or any other military or trade disruptions, may adversely impact Colombia’s economy by causing, among other things, supply chain disruptions, market volatility, changes in commodity prices and shortages of raw materials. In addition, because international investors’ reactions to the events occurring in one emerging market country sometimes appear to demonstrate a “contagion” effect, in which an entire region or class of investments is disfavored by international investors, Colombia could be adversely affected by negative economic or financial developments in other emerging market countries. Colombia has been adversely affected by such contagion effects on a number of occasions, including following the 1997 Asian financial crisis, the 1998 Russian financial crisis, the 1999 devaluation of the Brazilian real, the 2001 Argentine financial crisis, the global economic crisis that began in 2008 and the COVID-19 pandemic. Similar developments can be expected to affect the Colombian economy in the future.

There can be no assurance that any crises such as those described above or similar events will not negatively affect investor confidence in emerging markets or the economies of the principal countries in Latin America, including Colombia. In addition, there can be no assurance that these events will not adversely affect Colombia’s economy and its ability to raise capital in the external debt markets in the future. See “Forward-Looking Statements” in the accompanying prospectus.

There can be no assurance that Colombia’s credit ratings will improve or remain stable, or that they will not be downgraded, suspended or cancelled by the rating agencies.

Colombia’s long-term foreign currency rating from S&P Global Ratings (“S&P”), which had been BB+ with a stable outlook since May 19, 2021, was revised to a negative outlook on January 18, 2024. Fitch Ratings, Inc. (“Fitch”) has maintained Colombia’s long-term foreign currency rating at BB+ with a stable outlook since July 1, 2021, last affirmed on July 31, 2024. Colombia’s long-term foreign currency rating from Moody’s Investors Services Inc. (“Moody’s”), which had been Baa2 with a stable outlook since May 23, 2019, was revised to a negative outlook on June 27, 2024.

Ratings address the creditworthiness of Colombia and the likelihood of timely payment of Colombia’s long- term debt securities. Ratings are not a recommendation to purchase, hold or sell securities and may be changed, suspended or withdrawn at any time. Colombia’s current ratings and the rating outlooks currently assigned to it depend, in part, on economic conditions and other factors that affect credit risk and are outside the control of Colombia, as well as assessments of the creditworthiness of its productive state-owned enterprises.

There can be no assurances that Colombia’s credit ratings will be maintained or that they will not be downgraded, suspended or cancelled. Any credit rating downgrade, suspension or cancellation may have an adverse effect on the market price and the trading of the bonds.

Capitalized terms not defined in this section have the meanings ascribed to them in the 2023 Annual Report.

Republic of Colombia

Domestic Initiatives

On October 2, 2024, the Senate elected Gregorio Eljach Pacheco as the new Attorney General for the 2025-2029 term.

On October 8, 2024, the National Electoral Council decided to open an investigation and file charges against the presidential campaign of the “Coalición Pacto Histórico” for the alleged violation of the campaign spending limit and the alleged use of prohibited funding. The investigation involves President Gustavo Petro, as the presidential candidate of the coalition, Ricardo Roa Barragán, as campaign manager, Lucy Aydee Mogollón Alfonso, as campaign treasurer, and Maria Lucy Soto Caro and Juan Carlos Lemus Gómez, as campaign auditors. The investigation also includes the “Movimiento Político Colombia Humana” and the “Partido Político Unión Patríotica” as the political organizations responsible for the audit and presentation of reports regarding income and expenses of the “Coalición Pacto Histórico” presidential campaign. While Ricardo Roa Barragán is the current President of Ecopetrol, the investigation involves him in his capacity as campaign manager for alleged actions that would have taken place before he joined Ecopetrol as its President, and not during his time as Ecopetrol’s President or Ecopetrol itself.

On October 17, 2024, the Chamber of Representatives approved the labor reform bill with 93 votes in favor and 13 votes against. The bill includes provisions for paid leave for medical appointments, educational commitments, union commissions and domestic calamities, as well as paternity leave for up to 4 weeks.

Other relevant provisions that have been approved include: (i) promoting an employment program for victims of the armed conflict; (ii) the implementation of employment contracts for students of the National Learning Service (SENA), which will replace former apprenticeship contracts; and (iii) the assurance of labor rights for delivery workers providing services through digital platforms.

This reform is still subject to the approval of the Senate, where it will undergo two more rounds of discussions.

On October 22, 2024, the Senate initiated the sixth debate to discuss a constitutional amendment bill aimed at reforming the general participation system (the “GPS Reform Bill”), which is the mechanism through which the Government transfers to municipalities, districts and departments the resources that are needed to fund basic public services, such as education, healthcare and water and sewage. In this context, the GPS Reform Bill seeks to increase the transfers of State funds to territories, especially the most vulnerable, as well as strengthen territorial autonomy for the deployment of resources and execution of projects. As part of the Senate’s sixth debate on the GPS Reform Bill, the President of the Senate scheduled the continuation of such debate as well as a vote on the GPS Reform Bill for Monday, October 28, 2024.

On October 24, 2024, the Ministry of Finance published a statement in which it emphasized the importance of the approval of the GPS Reform Bill within the current regulatory frameworks, fiscal sustainability limits and debt compliance measures as well as the need to balance governmental functions and resources without putting Colombia’s finances at risk. In the statement, the Ministry further emphasized that in order for the GPS Reform Bill to enter into law, a separate bill which transfers governmental functions and ensures fiscal sustainability to territorial departments, districts and municipalities should also be discussed and approved. In its statement, the

S-15

Ministry of Finance clarified that its opinions issued so far in respect of the GPS Reform Bill have been based on the drafts approved in the previous debates, which are subject to change and which did not define clearly how the new framework provided in the GPS Reform Bill, if approved, would interact with the current framework of territorial governmental functions.

Guerrilla Activity

On October 15, 2024, the Government presented to the United Nations Security Council the “Shock plan to accelerate the implementation of the Final Peace Agreement”, which was signed in 2016 with the former FARC guerrilla group. This plan seeks to ensure a quick and effective progress in implementing the peace agreement in the territories most affected by the armed conflict. The plan focuses on concrete and high-impact initiatives in areas such as a comprehensive rural reform, development programs with a territorial focus and territorial security.

On October 16, 2024, the Government issued Decree No. 1280 of October 15, 2024, which extends the ceasefire with certain FARC dissident groups for an additional six-month period. The decree emphasizes that actions carried out by the armed forces and police against illegal economic activities will not be suspended.

Criminal Activity

As of and for the eight-month period ended August 31, 2024, 157 kidnapping incidents were reported, reflecting a 31% decrease from the 226 incidents reported during the same period in 2023. For the eight-month period ended August 31, 2024, 116 terrorism incidents were reported, reflecting a 26% decrease from the 157 terrorism incidents reported in the same period in 2023.

Corruption Investigations

On July 4, 2024, the Prosecutor General’s Office accused Natalia Isaza Velásquez of money laundering for allegedly having received Ps.59 million related to a fraudulent invoice for unperformed topological and geological activities related to the design of the second bridge between Plato (Magdalena) – Zambrano (Bolívar) under the Ruta del Sol III concession contract.

On September 5, 2024, the Prosecutor General’s Office initiated investigations to identify those responsible for the potentially illegal acquisition and use of “Pegasus” spyware by the Police Intelligence Bureau of the National Police. This purchase, allegedly made in mid-2021 from the Israeli firm NSO Group, is under scrutiny for its potential role in alleged illegal interceptions and monitoring of judges and employees of Colombia’s highest courts.

On September 10, 2024, the Attorney General’s Office launched a preliminary investigation into alleged irregularities surrounding the acquisition and operation of the intelligence software “Pegasus.” The Attorney General’s Office will collect evidence about the contracting process, the funds used for the purchase of the software and information about the operation of the software.

On October 16, 2024, the Attorney General’s Office filed charges against Sneyder Pinilla Álvarez, the former deputy director of Disaster Management of the Unidad Nacional para la Gestión del Riesgo de Desastres (UNGRD) from 2023 to 2024, for undue participation in politics. According to the investigators, the former deputy director used his position and image to support the electoral campaign of Darío Buchenicow Caballero, who was a candidate for mayor of the municipality of Sabana de Torres (Santander) for the 2024-2027 term.

Foreign Affairs

On October 9, 2024, Colombia was elected as a member of the United Nations Human Rights Council, securing one of the 47 seats of the multilateral body.

Economy

Unconventional Reservoir Projects

On October 3, 2024, the Government, through the Ministry of Mines and Energy and Ecopetrol Group, confirmed the discovery of gas in the Sirius project, formerly known as Uchuva-2, with a potential of nearly 6 cubic terafeet, which represents approximately 2.5 times the country’s current gas reserves, estimated at 2.3 cubic terafeet as of the end of 2023. The gas well is located in the Tayrona Block, approximately 31 km from the coast, and is operated by Petrobras, which holds a 44.44% stake, while Ecopetrol holds a 55.56% stake.

As of September 30, 2024, the year-over-year Producer Price Index (“PPI”) increased by 0.7%, mainly due to an increase in prices of agriculture, livestock and fishing (7.8%) and industry (2.9%).

As of September 30, 2024, the Fixed Term Deposit rate (“DTF”) was 9.7%.

Public Sector Finance

General

On September 6, 2024, the Government made another adjustment to the diesel prices, setting the average price at Ps.9,856 per gallon.

On September 10, 2024, the Ministry of Finance submitted the Financing Law Bill to Congress, which aims to create favorable conditions for economic recovery and secure the necessary resources for the country’s social transformation, with a projected tax revenue of Ps.12 trillion. Notwithstanding the projected tax revenue, the Financing Law Bill includes a gradual reduction of the corporate income tax rate from 35% to 27.3% and a reduction of the 19% VAT to an exempt rate for hotel and tourism services in municipalities with a population of less than 200,000 inhabitants.

Public Sector Accounts

For 2024, the Central Government’s projected deficit is 5.6% of GDP (compared to a deficit of 4.3% of GDP for 2023), while projected revenues amount to Ps.288,737 billion and projected expenditures amount to Ps.383,664 billion.

2025 Budget

On July 30, 2024, the Ministry of Finance submitted the 2025 National General Budget (“2025 PGN”) to Congress. However, for the first time in the country’s history, the Government plans to sign the 2025 PGN into law by decree, as provided by the constitutional provisions that govern the budget approval process, because the economic committees in Congress failed to reach the necessary quorum to vote on the 2025 PGN. The President must sign the 2025 PGN into law before December 30^th, 2024.

The 2025 PGN provides a budgeted amount of Ps.523 trillion, 3.9% higher than the budget of 2024. Of the budgeted amount, expenditures in the aggregate amount of Ps.12 trillion are contingent, meaning they depend on the approval of the Financing Law Bill submitted to Congress on September 10, 2024 and the corresponding increase in the projected tax revenue.

Public Sector Debt

As of September 30, 2024, the Central Government gross debt totaled Ps.969,854 billion, equivalent to 57.6% of GDP, of which internal debt totaled Ps.636,901 billion (37.8% of GDP) and external debt totaled Ps.332,953 billion (19.8% of GDP). In the second semester of 2024, net debt of the Central Government totaled Ps.932,957 billion, equivalent to 55.4% of GDP, of which internal debt totaled Ps.610,696 billion (36.3% of GDP) and external debt totaled Ps.322,262 billion (19.1% of GDP).

Public Sector Internal Debt

As of September 30, 2024, the Central Government’s total direct internal funded debt (with an original maturity of more than one year) was Ps.642,759 billion, compared to Ps.556,713 billion as of September 30, 2023.

DESCRIPTION OF THE BONDS

This prospectus supplement describes the terms of the bonds in greater detail than the accompanying prospectus and may provide information that differs from the accompanying prospectus. If the information in this prospectus supplement differs from the accompanying prospectus, you should rely on the information in this prospectus supplement.

Colombia will issue the bonds under an indenture, dated as of January 28, 2015, as supplemented by the first supplemental indenture dated as of September 8, 2015, between Colombia and The Bank of New York Mellon, as trustee. The information contained in this section and in the accompanying prospectus summarizes some of the terms of the bonds and the indenture. Because this is a summary, it does not contain all of the information that may be important to you as a potential investor in the bonds. Therefore, you should read the indenture and the form of the bonds in making your investment decision. Colombia has filed copies of these documents with the SEC and also filed copies of these documents at the offices of the trustee and the paying agents.

General Terms of the Bonds

The bonds offered by this prospectus supplement will:

• be issued on   , 2024, in an initial aggregate principal amount of U.S. $   ;

• mature at par on   , 2036;

• be issued in denominations of U.S. $200,000 and integral multiples of U.S. $1,000 in excess thereof;

• bear interest at  % per year, accruing from  , 2024;

• pay interest in U.S. dollars on and of each year. The first interest payment will be made on   , 2025. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months;

• pay interest to persons in whose names the bonds are registered at the close of business on  or   , as the case may be, preceding each payment date;

• be represented by one or more global securities in fully registered form only, without coupons;

• be registered in the name of a nominee of The Depository Trust Company, known as DTC, and recorded on, and transferred through, the records maintained by DTC and its participants, including the depositaries for Euroclear Bank SA/NV, as operator of the Euroclear System plc (“Euroclear”), and Clearstream Banking, S.A. (“Clearstream”);

• be available in definitive, certificated form only under certain limited circumstances;

• be redeemable at the option of Colombia, in whole or in part, before maturity, on not less than 10 nor more than 60 days’ notice on the terms described under “—Optional Redemption;” and

• not be entitled to the benefit of any sinking fund.

The public offering price is    %, and the resulting yield to maturity (calculated on a semi-annual basis) is %. The yield is calculated on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) on the issue date on the basis of the public offering price. It is not an indication of future yield.

Optional Redemption

Prior to   ,   (three months prior to their maturity date) (the “Par Call Date”), Colombia may redeem the bonds at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

S-24

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the bonds matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus    basis points less (b) interest accrued to the date of redemption, and

(2) 100% of the principal amount of the bonds to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date.

On or after the Par Call Date, Colombia may redeem the bonds, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the bonds being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

“Treasury Rate” means, with respect to any redemption date, the yield determined by Colombia in accordance with the following two paragraphs.

The Treasury Rate shall be determined by Colombia after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, Colombia shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, Colombia shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, Colombia shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, Colombia shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Colombia’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

S-25

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of bonds to be redeemed. A notice of redemption will specify the redemption date and may provide that it is subject to certain conditions that will be specified in the notice. If those conditions are not met, the redemption notice will be of no effect and Colombia will not be obligated to redeem the bonds.

In the case of a partial redemption, selection of the global bonds for redemption will be made on a basis as a “Pro Rata Pass Through Distribution of Principal” in accordance with the applicable rules and procedures of the depositary, or in the case of certificated bonds, any other method in accordance with the policies and procedures of the trustee. No bonds of a principal amount of U.S.$200,000 or less will be redeemed in part. If any bond is to be redeemed in part only, the notice of redemption that relates to the bond will state the portion of the principal amount of the bond to be redeemed. A new bond in a principal amount equal to the unredeemed portion of the bond will be issued in the name of the holder of the bond upon surrender for cancellation of the original bond. For so long as the bonds are held by DTC (or another depositary), the redemption of the bonds shall be done in accordance with the policies and procedures of the depositary.

Unless Colombia defaults in the payment of the redemption price, on and after the redemption date interest will cease to accrue on the bonds or portions thereof called for redemption.

Payment of Principal and Interest

Colombia will make payments of principal and interest on the bonds represented by global securities by wire transfer of U.S. dollars in immediately available funds to DTC or to its nominee as the registered holder of the bonds, which will receive the funds for distribution to the owners of beneficial interests in the bonds. Colombia will make these payments by making the funds available to the trustee in time for payments to be made on the bonds when due by the trustee or another paying agent.

Colombia has been informed by DTC that the owners will be paid in accordance with the procedures of DTC and its participants. None of Colombia, the trustee or any paying agent shall have any responsibility or liability for any of the records of, or payments made by, DTC or its nominee.

If the bonds are issued in definitive, certificated form, Colombia will make its interest and principal payments to you, if you are the person in whose name the certificated bonds are registered, by wire transfer if:

• you own at least U.S. $1,000,000 aggregate principal amount of the bonds; and

• not less than 15 days before the payment date, you notify the trustee or any paying agent of your election to receive payment by wire transfer and provide it with your bank account information and wire transfer instructions;

or

• Colombia is making such payments at maturity; and

• you surrender the certificated bonds at the corporate trust office of the trustee or at the offices of one of the other paying agents that Colombia appoints pursuant to the indenture.

Colombia will make these payments by making the funds available to the trustee in time for payments to be made on the bonds when due by the trustee or another paying agent. If Colombia does not pay interest by wire transfer for any reason, it will, subject to applicable laws and regulations, mail or cause to be mailed a check on or before the due date for the payment. The check will be mailed to you at your address as it appears on the security register maintained by the trustee on the applicable record date. If you hold your bonds through DTC, the check will be mailed to DTC, as the registered owner.

If any date for an interest or principal payment is a day on which the law (or an executive order) at the place of payment permits or requires banking or trust institutions to close, Colombia will make the payment on the next

S-26

following business day at such place. Colombia will treat those payments as if they were made on the due date, and no interest on the bonds will accrue as a result of the delay in payment.

Paying Agent and Transfer Agent

Until all of the bonds are paid, Colombia will maintain a paying agent in The City of New York. Colombia has initially appointed The Bank of New York Mellon to serve as its paying agent. You can contact the paying agent and transfer agent at the addresses listed on the inside back cover of this prospectus supplement. The Bank of New York Mellon, in each of its capacities, including without limitation as trustee, registrar, paying agent and transfer agent, assumes no responsibility for the accuracy or completeness of the information contained in this document or the related documents or for any failure by Colombia or any other party to disclose events that may have occurred and may affect the significance or accuracy of such information.

Notices

All notices to the holders while the bonds are in book-entry form, will be sent to the depositary or its nominee, as a holder thereof, and the depositary will communicate such notices to its participants in accordance with its standard rules. All notices while the bonds are in definitive, certificate form, will be mailed to the holders of the bonds at the addresses appearing in the security register maintained by the trustee. Colombia will consider a notice to be given at the time it is mailed. So long as the bonds are listed on the Luxembourg Stock Exchange and the rules of the exchange so require, Colombia will also publish notices to the holders in a leading newspaper having general circulation in Luxembourg or on the website of the Luxembourg Stock Exchange at http://www.luxse.lu. If publication in a leading newspaper in Luxembourg or on the website of the Luxembourg Stock Exchange at http://www.luxse.lu is not practicable, Colombia will give notices in an English language newspaper with general circulation in the respective market regions or in another way consistent with the rules of the Luxembourg Stock Exchange.

All notices regarding the bonds will also be published in a daily newspaper of general circulation in London for so long as the bonds are listed on the London Stock Exchange and the rules of the London Stock Exchange so require. If at any time the publication in any such newspaper is not practicable, notices will be valid if published in such English language newspaper with general circulation in the respective market regions as Colombia shall determine. Any such notice shall be deemed to have been given on the date of such publication or, if published more than once on different dates, on the first date on which publication is made.

Registration and Book-Entry System

Colombia will issue the bonds in the form of one or more fully registered global securities, registered in the name of a nominee of DTC. Financial institutions, acting as direct and indirect participants in DTC, will hold your beneficial interests in a global security. These financial institutions will record the ownership and transfer of your beneficial interests through book-entry accounts, eliminating the need for physical movement of bonds.

If you wish to purchase bonds under the DTC system, you must either be a direct participant in DTC or make your purchase through a direct participant in DTC. Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and other organizations which have accounts with DTC. Euroclear and Clearstream participate in DTC through their New York depositaries. Indirect participants are securities brokers and dealers, banks and trust companies that do not have an account with DTC, but that clear through or maintain a custodial relationship with a direct participant. Thus, indirect participants have access to the DTC system through direct participants. The SEC has on file a set of the rules applicable to DTC and its participants.

You may hold your beneficial interest in a global security through Euroclear or Clearstream, or indirectly through organizations that are participants in these systems. Euroclear and Clearstream will hold their participants’ beneficial interests in a global security in their customers’ securities accounts with their

S-27

depositaries. These depositaries of Euroclear and Clearstream in turn will hold such interests in their customers’ securities accounts with DTC. Euroclear’s or Clearstream’s ability to take actions as a holder under the bonds or the indenture will be limited by the ability of their respective depositaries to carry out actions for them through DTC.

In sum, you may elect to hold your beneficial interests in the global security:

• in the United States, through DTC;

• in Europe, through Euroclear or Clearstream, which in turn will hold their interests through DTC; or

• through organizations that participate in any of these systems.

Certificated Bonds

Colombia will issue bonds in certificated form in exchange for a global security only if:

• the depositary notifies Colombia that it is unwilling or unable to continue as depositary, is ineligible to act as depositary or ceases to be a clearing agency registered under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”) and Colombia does not appoint a successor depositary or clearing agency within 90 days;

• the trustee has instituted or has been directed to institute any judicial proceeding to enforce the rights of the holders under the bonds and has been advised by its legal counsel that it should obtain possession of the securities for the proceeding; or

• Colombia elects not to have the bonds represented by a global security or securities.

If a physical or certificated security becomes mutilated, defaced, destroyed, lost or stolen, Colombia may execute, and the trustee shall authenticate and deliver, a substitute security in replacement. In each case, the affected holder will be required to furnish to Colombia and to the trustee an indemnity under which it will agree to pay Colombia, the trustee and any of their respective agents for any losses that they may suffer relating to the security that was mutilated, defaced, destroyed, lost or stolen. Colombia and the trustee may also require that the affected holder present other documents or proof. The affected holder may be required to pay all taxes, expenses and reasonable charges associated with the replacement of the mutilated, defaced, destroyed, lost or stolen security.

If Colombia issues certificated securities, a holder of certificated securities may exchange them for securities of a different authorized denomination by submitting the certificated securities, together with a written request for an exchange, at the office of the trustee as specified in the indenture in New York City, or at the office of any transfer agent. In addition, the holder of any certificated security may transfer it in whole or in part by surrendering it at any of such offices together with an executed instrument of transfer.

Colombia will not charge the holders for the costs and expenses associated with the exchange, transfer or registration of transfer of certificated securities. Colombia may, however, charge the holders for certain delivery expenses as well as any applicable stamp duty, tax or other governmental or insurance charges. The trustee may reject any request for an exchange or registration of transfer of any security made within 15 days of the date for any payment of principal of, or premium or interest on the securities.

Jurisdiction; Enforceability of Judgments

Colombia is a foreign sovereign. It may, therefore, be difficult for investors to obtain or enforce judgments against Colombia.

S-28

Colombia will appoint the Consul General of Colombia in The City of New York and his or her successors from time to time as its process agent for any action arising out of or based on the bonds instituted in any state or federal court in the Borough of Manhattan, The City of New York.

Colombia will irrevocably submit to the exclusive jurisdiction of any state or federal court in the Borough of Manhattan, The City of New York and the courts of Colombia that sit in Bogotá D.C. in respect of any action brought by a holder based on the bonds. Colombia will also irrevocably waive any objection to the venue of any of these courts in an action of that type. Holders of the bonds may, however, be precluded from initiating actions arising out of or based on the bonds in courts other than those mentioned above.

Subject to the next sentence hereof, Colombia will, to the fullest extent permitted by law, irrevocably waive and agree not to plead any immunity from the jurisdiction of any of the above courts in any action based upon the bonds. This waiver covers Colombia’s sovereign immunity and immunity from prejudgment attachment, post- judgment attachment and execution except as provided under (i) Articles 192, 195, 298 and 299 of Law 1437 of 2011 (Código de Procedimiento Administrativo y de lo Contencioso Administrativo) as amended by Articles 80, 81 and 87 of Law 2080 of 2021; (ii) Articles 593, 594 and 595 et al. of Law 1564 of 2012 (Código General del Proceso), and (iii) Article 19 of Decree 111 of January 15, 1996, pursuant to which the revenues, assets and property of the Republic located in the Republic are not subject to execution, set-off or attachment.

Nevertheless, Colombia reserves the right to plead sovereign immunity under the U.S. Foreign Sovereign Immunities Act of 1976, as amended (the “Immunities Act”), in actions brought against it under the United States federal securities laws or any state securities laws. Colombia’s appointment of its process agent will not extend to these actions. Without Colombia’s waiver of immunity, you will not be able to obtain a United States judgment against Colombia in such actions unless the court determines that Colombia is not entitled under the Immunities Act to sovereign immunity. In addition, execution upon property of Colombia located in the United States to enforce a judgment obtained under the Immunities Act may not be possible except in the limited circumstances specified in the Immunities Act.

Even if you are able to obtain a judgment against Colombia in an action under the United States federal securities laws or any state securities laws, you might not be able to enforce it in Colombia. Your ability to enforce foreign judgments in Colombia is dependent, among other factors, on such judgments not violating the principles of Colombian public order. The Head or Acting Head of the Legal Affairs Group of the General Directorate of Public Credit and National Treasury of the Ministry of Finance and Public Credit of Colombia will render an opinion on this matter in connection with the issuance of the bonds.

S-29

TAXATION

United States Federal Taxation

The following discussion supplements the disclosure provided under the heading “Taxation—United States Federal Taxation” in the accompanying prospectus. This discussion describes the material U.S. federal income tax consequences of your purchase, ownership and disposition of a bond acquired at the issue price pursuant to this offering. The discussion is based on the provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), and the regulations promulgated thereunder by the U.S. Department of the Treasury (the “Treasury Regulations”), rulings and judicial decisions interpreting the Code as of the date that this prospectus supplement was issued. These authorities may be repealed, revoked or modified, possibly with retroactive effect. No assurances can be given that any changes in these laws or authorities will not affect the accuracy of the discussions set forth in this summary. This discussion does not cover any U.S. state, U.S. local or non-U.S. tax issues, nor does it cover issues under the U.S. federal estate or gift tax laws.

Colombia has not sought any ruling from the U.S. Internal Revenue Service (the “IRS”) with respect to the statements made and the conclusions reached in this discussion, and there can be no assurance that the IRS will agree with all of such statements and conclusions. A different treatment from that described below could adversely affect the amount, timing, and character of income, gain or loss in respect of an investment in the bonds.

This discussion deals only with beneficial owners that hold a bond as a capital asset for U.S. federal income tax purposes (generally, property held for investment). This discussion does not purport to deal with all aspects of U.S. federal income taxation that may be relevant to a particular holder in light of the holder’s circumstances.

In particular, this discussion assumes that you are not subject to any special U.S. federal income tax rules, including, among others, the special tax rules applicable to:

• persons subject to special tax accounting rules under Section 451(b) of the Code;

• dealers in securities or currencies;

• securities traders using a mark-to-market accounting method;

• banks or life insurance companies;

• regulated investment companies;

• real estate investment trusts;

• persons subject to the alternative minimum tax;

• persons that purchase or sell bonds as part of a wash sale for U.S. federal income tax purposes;

• persons that purchase or sell bonds as part of a hedging transaction or as a position in a straddle or conversion transaction;

• partnerships or other entities treated as partnerships for U.S. federal income tax purposes, or persons holding the bonds through partnerships or other pass-through entities;

• U.S. Holders (as defined below) that do not use the U.S. dollar as their functional currency; or

• tax-exempt organizations.

If a partnership (including any entity treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of a bond, the tax treatment of a partner in that partnership generally will depend on the status of the partner and the activities of the partnership. Holders of bonds that are partnerships and partners in those partnerships should consult their own tax advisor regarding the U.S. federal income tax consequences of purchase, ownership and disposition of the bonds.

S-30

In certain circumstances (see “Description of the Bonds—Optional Redemption”), the Republic may be obligated to pay additional amounts to optionally redeem the bonds. These potential payments may implicate the provisions of the Treasury Regulations relating to “contingent payment debt instruments.” If the bonds have an issue price that does not exceed the stated principal amount of the bonds, then the foregoing potential obligation to pay certain additional amounts generally may be ignored under these regulations. Furthermore, under these regulations, a contingency should not cause a debt instrument to be treated as a contingent payment debt instrument if, as of the issue date, such contingency is considered “remote” or “incidental” or, in certain circumstances, it is significantly more likely than not that the contingency will not occur. The Republic intends to take the position that the foregoing potential obligation to pay certain additional amounts should not cause the bonds to be treated as contingent payment debt instruments for U.S. federal income tax purposes. The Republic’s position is binding on a holder unless such holder discloses its contrary position in the manner required by the applicable Treasury Regulations. It is possible that the IRS may take a different position, in which case, if such position is sustained, the timing and amount of income included and the character of the income recognized with respect to the bonds may be materially and adversely different from the consequences discussed herein. The remainder of this discussion assumes that the bonds will not be treated as contingent payment debt instruments. You should consult your own tax advisors regarding the possible application of the contingent payment debt instrument rules to the bonds.

Colombia expects, and the remainder of this summary assumes, that the bonds will be issued with less than a de minimis amount of “original issue discount” for U.S. federal income tax purposes.

You should consult your own tax advisor concerning the U.S. federal, U.S. state, U.S. local, non-U.S. and other tax consequences to you of the purchase, ownership or disposition of a bond.

Deemed Taxable Exchange

A change made to the terms of the bonds pursuant to the “collective action clauses” may give rise to a deemed taxable exchange of the bonds for U.S. federal income tax purposes upon which gain or loss is realized if the modified bond differs materially either in kind or extent from the original bond (a “Significant Modification”). Such gain or loss would generally be measured by the difference between the fair market value of the bond after the Significant Modification and the holder’s tax basis in such bond before the Significant Modification. A modification of a bond that is not a Significant Modification does not create a deemed exchange for U.S. federal income tax purposes. Under applicable Treasury Regulations, the modification of a bond is a Significant Modification if, based on all of the facts and circumstances and taking into account all modifications of the bond collectively (other than modifications that are subject to special rules), the legal rights or obligations that are altered and the degree to which they are altered is “economically significant.” The applicable Treasury Regulations also provide specific rules to determine whether certain modifications, such as a change in the timing of payments, are significant. See the discussion under “Description of the Securities—Meetings and Amendments—Collective Action Clause” in the accompanying prospectus for more information about potential amendments of certain key terms of the bonds.

U.S. Holders

This section applies to you if you are a “U.S. Holder,” meaning that you are the beneficial owner of a bond and you are:

• an individual who is a citizen or resident of the United States for U.S. federal income tax purposes;

• a corporation (or other entity classified as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any state thereof or the District of Columbia;

• an estate whose income is subject to U.S. federal income taxation regardless of its source; or

S-31

• a trust (A) if a court within the United States is able to exercise primary supervision over your administration and one or more “United States persons” as defined in the Code (each a “U.S. Person”) have authority to control all your substantial decisions, or (B) that was in existence on August 20, 1996 and has made a valid election under the Treasury Regulations to be treated as a U.S. trust.

If you are not a U.S. Holder, this section does not apply to you and you should refer to “—Non-U.S. Holders” below.

Payments of Interest. Payments or accruals of stated interest on a bond generally will be taxable to you as ordinary income. If you generally report your taxable income using the accrual method of accounting, you must include payments of interest in your income as they accrue. If you generally report your taxable income using the cash method of accounting, you must include payments of interest in your income when you actually or constructively receive them.

You must include any tax withheld from the interest payment as ordinary income even though you do not in fact receive it. You may be entitled to deduct or credit this tax, subject to applicable limits. You will also be required to include in income as interest any additional amounts paid with respect to withholding tax on the bonds, including withholding tax on payments of such additional amounts. For purposes of the foreign tax credit provisions of the Code, interest (including any additional amounts) on a bond generally will constitute foreign source income and will be categorized as passive or another category of income depending on your circumstances.

Disposition of Bonds. If you sell or otherwise dispose of a bond, you generally will recognize a gain or loss equal to the difference between your “amount realized” and your “adjusted tax basis” in the bond. Your “amount realized” generally will be the value of what you receive for selling or otherwise disposing of the bond, other than amounts that represent interest that is due to you but that has not yet been paid (which, generally will be taxed to you as ordinary income to the extent not previously included in income). Your “adjusted tax basis” in the bond generally will equal the amount that you paid for the bond.

Gain or loss from the sale or other disposition of a bond generally will be capital gain or loss, and will be long-term capital gain or loss if at the time you sell or dispose of the bond, you have held the bond for more than one year, or will be short-term capital gain or loss if you have held the bond for one year or less. Net capital gains of non-corporate taxpayers may be taxed at lower rates than items of ordinary income. Your ability to offset capital losses against ordinary income is limited. Any capital gains or losses that arise when you sell or dispose of a bond generally will be treated as U.S. source income, or loss allocable to U.S. source income, for purposes of the foreign tax credit provisions of the Code.

Medicare Tax. A U.S. Holder that is an individual or estate, or a trust that does not fall into a special class of trusts that is exempt from such tax, will be subject to a 3.8% Medicare tax on the lesser of (i) the U.S. Holder’s “net investment income” (or, in the case of an estate or trust, the “undistributed net investment income”) for the relevant taxable year and (ii) the excess of the U.S. Holder’s modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000, depending on the individual’s circumstances). A U.S. Holder’s net investment income generally will include its interest income and its net gains from the disposition of the bonds, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). If you are an individual, estate or trust, you are urged to consult your own tax advisor regarding the applicability of the Medicare tax to your income and gains in respect of your investment in the bonds.

Information with Respect to Foreign Financial Assets. Owners of “specified foreign financial assets” with an aggregate value in excess of $50,000 on the last day of the taxable year, or $75,000 at any time during the taxable year may be required to file information reports with respect to such assets with their U.S. federal income

S-32

tax returns. Depending on your circumstances, higher threshold amounts may apply. “Specified foreign financial assets” include any financial accounts maintained by non-U.S. financial institutions, as well as securities held for investment and issued by non-U.S. Persons that are not held in accounts maintained by financial institutions (which may include the bonds issued in certified form). Failure to file information reports may subject you to penalties. In addition, the statute of limitations for assessment of tax would be suspended in whole or part. You should consult your own tax advisor regarding your obligation to file information reports with respect to the bonds.

Non-U.S. Holders

This section applies to you if you are a “Non-U.S. Holder,” meaning that you are a beneficial owner of a bond and are not a partnership for U.S. federal income tax purposes and not a “U.S. Holder” as defined above.

Payments of Interest. Subject to the discussion of backup withholding below, you generally will not be subject to U.S. federal income tax, including withholding tax, on interest that you receive on a bond unless you are engaged in a trade or business in the United States and the interest on the bond is treated for U.S. federal income tax purposes as “effectively connected” to that trade or business (and in addition, if an income tax treaty applies, the interest is attributable to a permanent establishment or fixed place of business maintained by you within the United States). If you are engaged in a U.S. trade or business and the interest income is deemed to be effectively connected to that trade or business, you generally will be subject to U.S. federal income tax on that interest in the same manner as if you were a U.S. Holder (unless the interest is excluded under an applicable tax treaty). In addition, if you are a corporation for U.S. federal income tax purposes, your interest income subject to tax in that manner may increase your liability under the U.S. branch profits tax currently imposed at a 30% rate (or a lower rate under an applicable tax treaty).

Disposition of Bonds. Subject to the backup withholding discussion below, you generally will not be subject to U.S. federal income tax or withholding tax for any capital gain that you realize when you sell or otherwise dispose of a bond unless:

1. that gain is effectively connected for U.S. federal income tax purposes to any U.S. trade or business you are engaged in (and in addition, if an income tax treaty applies, the gain is attributable to a permanent establishment or fixed base in the United States); or

2. if you are an individual, you are present in the United States for 183 days or more in the taxable year in which you sell or otherwise dispose of the bond and either (i) you have a tax home (as defined in the Code) in the United States during the taxable year in which you sell or otherwise dispose of the bond, or (ii) the gain is attributable to any office or other fixed place of business that you maintain in the United States.

If you are described under (1) above, you generally will be subject to U.S. federal income tax on such gain in the same manner as a U.S. Holder and, if you are a corporation for U.S. federal income tax purposes, you may also be subject to the U.S. branch profits tax as described above. If you are described under (2) above, you generally will be subject to a 30% U.S. federal tax on the gain derived from the sale or other taxable disposition of a bond, which may be offset by certain U.S. source capital losses (notwithstanding the fact that you are not considered a U.S. resident for U.S. federal income tax purposes). Any amount attributable to accrued but unpaid interest on a bond generally will be treated in the same manner as payments of interest made to you, as described above under “—Payments of Interest.”

Backup Withholding and Information Reporting

If you are a U.S. Holder, and unless you prove that you are exempt, information reporting requirements will apply to payments of principal and interest to you if such payments are made within the United States or by or through a custodian or nominee that is a “U.S. Controlled Person,” as defined below. Backup withholding will

S-33

apply to such payments of principal and interest if (i) you fail to provide an accurate taxpayer identification number; (ii) in the case of interest payments, you fail to certify that you are not subject to backup withholding; (iii) you are notified by the IRS that you have failed to report all interest and dividend income required to be shown on your U.S. federal income tax returns; or (iv) you fail to demonstrate your eligibility for an exemption.

If you are a Non-U.S. Holder, you generally are exempt from these withholding and reporting requirements, but you may be required to comply with certification and identification procedures in order to prove your exemption. If you are paid the proceeds of a sale or redemption of a bond effected at the U.S. office of a broker, you generally will be subject to the information reporting and backup withholding rules. In addition, the information reporting rules will apply to payments of proceeds of a sale or redemption effected at a non-U.S. office of a broker that is a “U.S. Controlled Person,” as defined below, unless the broker has documentary evidence that the holder or beneficial owner is not a U.S. Holder or the holder or beneficial owner otherwise establishes an exemption. A U.S. Controlled Person includes:

• a U.S. Person;

• a controlled foreign corporation for U.S. federal income tax purposes;

• a non-U.S. Person 50% or more of whose gross income is effectively connected with a U.S. trade or business for tax purposes for a specified three-year period; or

• a non-U.S. partnership in which U.S. Persons hold more than 50% of the income or capital interests or which is engaged in a U.S. trade or business.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to you generally will be allowed as a refund or a credit against your U.S. federal income tax liability as long as you provide the required information to the IRS in a timely manner.

S-34

UNDERWRITING (CONFLICTS OF INTEREST)

Under the terms and subject to the conditions contained in an underwriting agreement dated as of , 2024, Colombia has agreed to sell to the underwriters named below, and the underwriters have severally agreed to purchase, the principal amount of the bonds indicated in the following table:

Underwriter	Principal Amount of Bonds
Citigroup Global Markets Inc.	U.S. $
Itau BBA USA Securities, Inc.	U.S. $
SMBC Nikko Securities America, Inc.	U.S. $
Total	U.S. $

The underwriting agreement provides that the underwriters are obligated to purchase all of the bonds if any are purchased. The underwriting agreement also provides that if an underwriter defaults, the offering of the bonds may be terminated. Citigroup Global Markets Inc. is located at 388 Greenwich Street, New York, New York 10013, Itau BBA USA Securities, Inc. is located at 540 Madison Avenue, 24th Floor New York, New York 10022 and SMBC Nikko Securities America, Inc. is located at 277 Park Avenue, New York, New York 10172. The underwriters may also offer and sell bonds through certain of their affiliates.

It is expected that delivery of the bonds will be made through the facilities of DTC on or about   , 2024, which is the eighth business day following the date hereof (such settlement cycle being referred to as “T+8”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the bonds prior to the business day before the settlement date will be required, by virtue of the fact that the bonds initially will settle in T+8, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the bonds who wish to trade the bonds prior to the business day before the settlement date should consult their own advisors.

The underwriters propose to offer the bonds initially at the public offering price on the cover page of this prospectus supplement and to securities dealers at that price less a selling concession of   % of the principal amount of the bonds. The underwriters and any such securities dealers may allow a discount of   % of the principal amount of the bonds on sales to other dealers. After the initial public offering of the bonds, the underwriters may change the public offering price and concession and discount to dealers.

The underwriters are acting as joint dealer managers and Citigroup Global Markets Inc. is acting as the billing and delivering bank (the “B&D Bank”) for Colombia’s tender offer on the terms and subject to the conditions set forth in the Offer to Purchase. The Offer to Purchase does not constitute a notice of redemption or obligate Colombia to issue a notice of redemption.

It is anticipated that Citigroup Global Markets Inc., as the B&D Bank for the tender offer, will purchase the tendered bonds pursuant to the Offer to Purchase on November 4, 2024, 3 business days prior to settlement of the bonds. On the settlement date of the bonds, the B&D Bank will be entitled to offset a portion of the net proceeds of this offering against the full amount due to the B&D Bank by Colombia for the tendered bonds purchased by the B&D Bank for delivery to Colombia, and the B&D Bank will pay the balance of the net proceeds of the bonds to Colombia.

Colombia has been advised by the underwriters that the underwriters intend to make a market in the bonds but are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of the trading market for the bonds.

In connection with the offering, the underwriters may purchase and sell the bonds in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short

S-35

sales. Short sales involve the sale by the underwriters of a greater number of the bonds than they are required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the bonds while the offering is in progress.

These activities by the underwriters, as well as other purchases by the underwriters for their own accounts, may stabilize, maintain or otherwise affect the market price of the bonds. As a result, the price of the bonds may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in the over-the-counter market or otherwise.

Colombia has agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments the underwriters may be required to make in respect of any of these liabilities.

The underwriters and their affiliates may have engaged and may in the future continue to engage in transactions with and perform services for Colombia, for which they received or will receive customary fees and expenses, in addition to the underwriting of this offering. These transactions and services are carried out in the ordinary course of business. In addition to the underwriting of this offering, Citigroup Global Markets Inc., Itau BBA USA Securities, Inc., and SMBC Nikko Securities America, Inc. are acting as dealer managers for Colombia’s Offer to Purchase for cash certain outstanding global bonds of Colombia on the terms and subject to the conditions set forth in the Offer to Purchase.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of Colombia. Certain underwriters or their affiliates, as part of routine market-making activity in respect of Colombia’s debt securities or any other exposure they may have to Colombian sovereign credit risk, may hedge such exposure consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by purchasing credit default swaps or creating short positions in Colombia’s securities, including potentially the bonds offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the bonds offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

The bonds are being offered for sale in jurisdictions in the United States and outside the United States where it is legal to make such offers. The underwriters have agreed that they will not offer or sell the bonds, or distribute or publish any document or information relating to the bonds, in any jurisdiction (including any Member State of the European Economic Area) without complying with the applicable laws and regulations of that jurisdiction.

As described in “Use of Proceeds,” some of the net proceeds of this offering may be used to fund Colombia’s purchase of certain outstanding bonds of Colombia from time to time. Citigroup Global Markets Inc., Itau BBA USA Securities, Inc. and SMBC Nikko Securities America, Inc. may be holders of certain of the outstanding bonds of Colombia as set forth in the Offer to Purchase and may receive 5% or more of the proceeds from this offering. As a result, this offering will be conducted in accordance with FINRA Rule 5121.

If you receive this prospectus supplement and the accompanying prospectus, then you must comply with the applicable laws and regulations of the jurisdiction where you (a) purchase, offer, sell or deliver the bonds or (b) possess, distribute or publish any offering material relating to the bonds. Your compliance with these laws and regulations will be at your own expense.

S-36

Republic of Colombia

Debt Securities

Warrants

Colombia may from time to time offer debt securities or warrants in amounts, at prices and on terms to be determined at the time of sale and to be set forth in supplements to this prospectus. Colombia may sell securities having an aggregate principal amount of up to $12,000,000,000 (or its equivalent in other currencies) in the United States.

The securities will be direct, general, unconditional, unsecured and unsubordinated external indebtedness of Colombia and will be backed by the full faith and credit of Colombia. The securities rank and will rank without any preference among themselves and equally with all other unsecured and unsubordinated external indebtedness of Colombia. It is understood that this provision shall not be construed so as to require Colombia to make payments under the securities ratably with payments being made under any other external indebtedness.

The securities will contain “collective action clauses,” unless otherwise indicated in the applicable prospectus supplement. Under these provisions, which differ from the terms of Colombia’s external indebtedness issued prior to January 28, 2015, Colombia may amend the payment provisions of the securities and other reserve matters listed in the indenture with the consent of the holders of: (1) with respect to a single series of securities, more than 75% of the aggregate principal amount outstanding of such series; (2) with respect to two or more series of securities, if certain “uniformly applicable” requirements are met, more than 75% of the aggregate principal amount of the outstanding securities of all series affected by the proposed modification, taken in the aggregate; or (3) with respect to two or more series of securities, more than 66 2/3% of the aggregate principal amount of the outstanding securities of all series affected by the proposed modification, taken in the aggregate, and more than 50% of the aggregate principal amount of the outstanding securities of each series affected by the proposed modification, taken individually.

Neither the Securities and Exchange Commission nor any state securities commission or any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that Colombia filed with the SEC under a “shelf” registration process. Under this shelf process Colombia may sell, from time to time, any of the debt securities or warrants described in this prospectus in one or more offerings up to a total U.S. dollar equivalent amount of $12,000,000,000. This prospectus provides you with a general description of the debt securities and warrants Colombia may offer under this shelf process. Each time Colombia sells securities under this shelf process, it will provide a prospectus supplement that will contain updated information about Colombia, if necessary, and specific information about the terms of that offering.

Any information contained in this prospectus may be updated or changed in a prospectus supplement, in which case the more recent information will apply. You should rely only on the information contained or incorporated by reference in this prospectus and any prospectus supplement.

FORWARD-LOOKING STATEMENTS

The following documents relating to Colombia’s debt securities or warrants may contain forward-looking statements:

• this prospectus;

• any prospectus supplement; and

• the documents incorporated by reference in this prospectus and any prospectus supplement.

Statements that are not historical facts, including statements about Colombia’s beliefs and expectations, are forward-looking statements. These statements are based on current plans, assumptions, estimates and projections, and therefore you should not place undue reliance on them. Forward-looking statements speak only as of the date they are made, and Colombia undertakes no obligation to update publicly any of them in light of new information or future events. Forward-looking statements involve inherent risks and uncertainties. Colombia cautions you that a number of important factors could cause actual results to differ materially from those contained in any forward-looking statement. Such factors include but are not limited to:

• Adverse external factors, such as high international interest rates, low oil prices, a global or regional pandemic, and recession or low growth in Colombia’s trading partners. High international interest rates could increase Colombia’s current account deficit and budgetary expenditures. Low oil prices could decrease the Government’s revenues and could also negatively affect the current account. Recession or low growth in Colombia’s trading partners could lead to fewer exports from Colombia and, therefore have a negative impact on Colombia’s growth.

• Adverse domestic factors, such as declines in foreign direct and portfolio investment, domestic inflation, high domestic interest rates, exchange rate volatility, political uncertainty and continuing insurgency in certain regions and adverse effects of climatic events. Each of these could lead to lower growth in Colombia and lower international reserves.

USE OF PROCEEDS

Unless otherwise specified in the applicable prospectus supplement, Colombia will use the net proceeds from the sale of the securities for general budgetary purposes.

DESCRIPTION OF THE SECURITIES

This prospectus provides you with a general description of securities that Colombia may offer. Each time Colombia sells securities, it will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus. If the information in this prospectus differs from any prospectus supplement, you should rely on the information in the prospectus supplement.

Debt Securities

Colombia will issue the debt securities under an indenture between Colombia and The Bank of New York Mellon, as trustee. Colombia has previously filed or will file the indenture (which may be supplemented from time to time), any supplements thereto and the form of debt securities with the SEC and will also file copies of these documents at the office of the trustee.

The following description is a summary of the material provisions of the debt securities and the indenture pursuant to which they are issued. Given that it is only a summary, the description may not contain all of the information that is important to you as a potential investor in these debt securities. Therefore, you should read the indenture and the form of the debt securities in making your decision on whether to invest in the debt securities.

General Terms

The prospectus supplement relating to any series of debt securities offered will include specific terms relating to the debt securities. These terms will include some or all of the following:

• the title;

• any limit on the aggregate principal amount;

• the issue price;

• the maturity date or dates;

• if the debt securities bear interest, the interest rate, which may be fixed or floating, the date from which interest will accrue, the interest payment dates and the record dates for these interest payment dates;

• any mandatory or optional sinking fund provisions;

• any provisions that allow Colombia to redeem the debt securities at its option;

• any provisions that entitle you to early repayment at your option;

• the currency or currencies that you may use to purchase the debt securities and that Colombia may use to pay principal, any premium and interest;

• the form of debt security (global or certificated and registered);

• the authorized denominations;

• any special U.S. federal income tax considerations;

• any index Colombia will use to determine the amount of principal, any premium and interest payment; and

• any other terms of the debt securities that do not conflict with the provisions of the indenture.

Colombia may issue debt securities in exchange for other debt securities or which are convertible into new debt securities. The specific terms of the exchange or conversion of any debt security and the debt security to which it will be exchangeable or converted will be described in the prospectus supplement relating to the exchangeable or convertible debt security.

Colombia may issue debt securities at a discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. If applicable, Colombia will describe the United States federal income tax consequences and any other relevant considerations in the applicable prospectus supplement for any issuance of debt securities.

3

Nature of Obligation

The debt securities constitute and will constitute direct, general, unconditional, unsecured and unsubordinated external indebtedness of Colombia and will be backed by the full faith and credit of Colombia. The debt securities rank and will rank without any preference among themselves and equally with all other unsecured and unsubordinated external indebtedness of Colombia. It is understood that this provision will not be construed so as to require Colombia to make payments under the debt securities ratably with payments made under any other external indebtedness.

Form and Denomination

Unless otherwise provided in the prospectus supplement for an offering, Colombia will issue debt securities:

• denominated in U.S. dollars;

• in fully registered book-entry form;

• without coupons; and

• in denominations of $2,000 and integral multiples of $1,000.

Payment of Principal and Interest

For each series of debt securities, Colombia will arrange for payments to be made on global debt securities by wire transfer to the applicable clearing system, or to its nominee or common depositary, as the registered owner or bearer of the debt securities, which will receive the funds for distribution to the holders. See “Description of the Securities—Global Securities” below.

Colombia will arrange for payments to be made on registered certificated debt securities on the specified payment dates to the registered holders of the debt securities. Colombia will arrange for such payments by wire transfer or by check mailed to the registered holders of the debt securities at their registered addresses. So long as the trustee has received from Colombia the funds required for the payment of the amounts due in respect of the debt securities and such funds are available to holders of the debt securities in accordance with the terms of the debt securities and the indenture and holders of the debt securities are not prevented from claiming such

funds in accordance with the terms of the debt securities and the indenture, Colombia shall not be considered to have defaulted in its obligation to make payment of such amounts on the date on which such amounts become due and payable.

Any money that Colombia pays to the trustee for payment on any debt security that remains unclaimed for two years will be returned to Colombia. Holders of any debt security will thereafter look only to the Republic for any payment which a Holder may be entitled to collect. To the extent permitted by law, claims against Colombia for the payment of principal, interest or other amounts will become void unless made within five years after the date on which the payment first became due, or a shorter period if provided by law.

Additional Amounts

Colombia will make all principal and interest payments on the debt securities of each series without deducting or withholding any present or future Colombian taxes, unless the deduction or withholding is required by law. In the event that Colombia is required to make any such deductions, it will pay the holders the additional amounts required to ensure that they receive the same amount as they would have received without this withholding or deduction.

Colombia will not, however, pay any additional amounts in connection with any tax, assessment or other governmental charge that is imposed due to any of the following:

• the holder or beneficial owner has some present or former connection with Colombia other than merely holding the debt security or receiving principal and interest payments on the debt security;

• the holder or beneficial owner fails to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection with Colombia of the holder or beneficial owner, if compliance is required by Colombia as a precondition to exemption from the deduction; or

4

• the holder does not present (where presentment is required) its debt security within 30 days after Colombia makes a payment of principal or interest available.

Redemption and Repurchase

Unless otherwise provided in the prospectus supplement for a series of debt securities, the debt securities will not be redeemable prior to maturity at the option of Colombia or repayable before maturity at the option of the holders. Nevertheless, Colombia may at any time purchase the debt securities and hold or resell them or surrender them to the trustee for cancellation.

Negative Pledge

Colombia will agree when it issues debt securities that as long as any of those debt securities remain outstanding, it will not create or permit to exist any lien (i.e., a lien, pledge, mortgage, security interest, deed of trust or charge), other than certain permitted liens, on its present or future revenues, properties or assets to secure its public external indebtedness, unless the debt securities are secured equally and ratably. As used in this prospectus, “public external indebtedness” means:

• all actual and contingent obligations of Colombia for borrowed money or for the repayment of which Colombia is responsible that are payable, or at the option of the holder may be payable, in any currency other than Colombian currency; and

• that are in the form of bonds, debentures, notes or other securities that are or were intended at the time of issue by Colombia to be quoted, listed or traded or which are ordinarily purchased and sold on any securities exchange, automated trading system, over-the-counter or other securities market, including securities eligible for resale pursuant to Rule 144A under the Securities Act of 1933.

Nevertheless, Colombia may create or permit to exist certain liens as described below:

• liens created before the date of the indenture, including renewals or refinancing of those liens; provided, however, that any renewal or refinancing of any of those liens secures only the renewal or extension of the original secured financing;

• any lien on property to secure public external indebtedness arising in the ordinary course of business to finance export, import or other trade transactions, which matures, after giving effect to all renewals and refinancings, not more than one year after the date on which this type of public external indebtedness was originally incurred;

• liens securing public external indebtedness incurred in connection with a project financing, as long as the security interest is limited to the assets or revenues of the project being financed. “Project financing” means any financing of all or part of the acquisition, construction or development costs of any project where the provider of the financing (a) agrees to limit its recourse to the project and the revenues of the project as the principal source of repayment and (b) has received a feasibility study prepared by competent independent experts on the basis of which it is reasonable to conclude that the project will generate sufficient foreign currency income to service substantially all public external indebtedness incurred in connection with the project;

• liens on any asset or property, and related revenues, to secure indebtedness borrowed for the purpose of financing the acquisition, development or construction of that asset or property;

• any renewal or extension of the above liens that is limited to the same asset or property, and related revenues, and that secures a renewal or extension of the original secured financing;

• liens existing on any asset or property and any related revenues, at the time of its acquisition and any renewal or extension of the above liens that is limited to the same asset or property and related revenues and that secures a renewal or extension of the original secured financing; and

5

• liens in addition to those permitted above, and any renewal or extension thereof; provided, that at any time the aggregate amount of public external indebtedness secured by such additional liens shall not exceed the equivalent of U.S.$14.768 billion.

Default and Acceleration of Maturity

Each of the following shall be an event of default under a series of debt securities:

1. Non-Payment: Colombia fails to pay any principal of or interest on any debt security of that series within 30 days of the date when the payment was due; or

2. Breach of Other Obligations: Colombia fails to perform any other material obligation contained in the debt securities of that series or the indenture and that failure continues for 60 days after the trustee or holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series give written notice to Colombia to remedy the failure; or

3. Cross Default on Direct Obligations: Colombia fails to pay when due any public external indebtedness (other than public external indebtedness constituting guaranties by Colombia) with an aggregate principal amount greater than $20,000,000 or the equivalent, and that failure continues beyond any applicable grace period or waiver; or

4. Cross Default on Guaranties: Colombia fails to pay when due any public external indebtedness constituting guaranties by Colombia with an aggregate principal amount greater than $20,000,000 or the equivalent, and that failure continues until the earlier of (a) the expiration of the applicable grace period or 30 days after written notice, whichever is longer, or (b) the acceleration of the public external indebtedness by any holder thereof and such acceleration shall not have been rescinded or annulled; or

5. Denial of Obligations: Colombia or any governmental entity of Colombia which has the legal power to contest the validity of the debt securities contests the validity of the debt securities of that series in any type of formal proceeding; or

6. Moratorium: Colombia declares a general suspension of payments or a moratorium on the payment of principal or interest on public external indebtedness which does not expressly exclude the debt securities of that series; or

7. IMF Membership: Colombia ceases to be a member of the IMF or ceases to be eligible to use the general resources of the IMF.

If any of the events of default described above occurs and is continuing, the trustee or the holders of at least 25% of the aggregate principal amount of the debt securities of the series then outstanding may declare all the debt securities of that series to be due and payable immediately by giving written notice to Colombia, with a copy to the trustee.

Holders holding debt securities representing in the aggregate more than 50% of the principal amount of the then-outstanding debt securities of that series may waive any existing defaults and their consequences on behalf of the holders of all of the debt securities of that series if:

• following the declaration that the principal of the debt securities of that series has become due and payable immediately, Colombia deposits with the trustee a sum sufficient to pay all outstanding amounts then due on those debt securities (other than principal due by virtue of the acceleration upon the event of default), together with interest on such amounts through the date of the deposit, as well as the reasonable fees and compensation of the holders that declared those notes due and payable, the trustee and their respective agents, attorneys and counsel; and

• all events of default (other than non-payment of principal that became due by virtue of the acceleration upon the event of default) have been remedied.

6

Suits for Enforcement and Limitations on Suits by Holders

If an event of default for a series has occurred and is continuing, the trustee may, in its discretion, institute judicial action to enforce the rights of the holders of that series. With the exception of a suit to enforce the absolute right of a holder to receive payment of the principal of and interest on debt securities in the manner contemplated in the indenture and the securities on the stated maturity date therefor (as that date may be amended or modified pursuant to the terms of the debt securities, but without giving effect to any acceleration), a holder has no right to bring a suit, action or proceeding with respect to the debt securities of a series unless: (1) such holder has given written notice to the trustee that a default with respect to that series has occurred and is continuing; (2) holders of at least 25% of the aggregate principal amount outstanding of that series have instructed the trustee by specific written request to institute an action or proceeding and provided an indemnity satisfactory to the trustee; and (3) 60 days have passed since the trustee received the instruction, the trustee has failed to institute an action or proceeding as directed and no direction inconsistent with such written request shall have been given to the trustee by a majority of holders of that series. Moreover, any such action commenced by a holder must be for the equal, ratable and common benefit of all holders of debt securities of that series.

Meetings and Amendments – Collective Action Clause

The debt securities will contain “collective action clauses,” which permit Colombia to amend the payment provisions and certain other “reserve matters” relating to the debt securities of a series with the consent of the holders of less than all of the affected series of debt securities. As described below, Colombia may amend such provisions of the debt securities with the consent of the holders of: (1) with respect to a single series of debt securities, more than 75% of the aggregate principal amount outstanding of such series; (2) with respect to two or more series of debt securities, if certain “uniformly applicable” requirements are met, more than 75% of the aggregate principal amount of the outstanding debt securities of all series affected by the proposed modification, taken in the aggregate; or (3) with

respect to two or more series of debt securities, more than 66 2/3% of the aggregate principal amount of the outstanding debt securities of all series affected by the proposed modification, taken in the aggregate, and more than 50% of the aggregate principal amount of the outstanding debt securities of each series affected by the proposed modification, taken individually.

Colombia may call a meeting of the holders of debt securities of a series at any time regarding the indenture or the debt securities of the series. Colombia will determine the time and place of the meeting. Colombia will notify the holders of the time, place and purpose of the meeting not less than 30 and not more than 60 days before the meeting.

In addition, Colombia or the trustee will call a meeting of holders of debt securities of a series if the holders of at least 10% in principal amount of all debt securities of the series then outstanding have delivered a written request to Colombia or the trustee (with a copy to Colombia) setting out the purpose of the meeting. Within 10 days of receipt of such written request or copy thereof, Colombia will notify the trustee, and the trustee will notify the holders, of the time, place and purpose of the meeting called by the holders, to take place not less than 30 and not more than 60 days after the date on which such notification is given.

Only holders and their proxies are entitled to vote at a meeting of holders. Colombia will set the procedures governing the conduct of the meeting and if additional procedures are required, Colombia will consult with the trustee to establish such procedures as are customary in the market.

Modifications may also be approved by holders of debt securities of a series pursuant to written action with the consent of the requisite percentage of debt securities of such series. Colombia will solicit the consent of the relevant holders to the modification not less than 10 and not more than 30 days before the expiration date for the receipt of such consents as specified by Colombia.

The holders may generally approve any proposal by Colombia to modify the indenture or the terms of the debt securities of a series with the affirmative vote (if approved at a meeting of the holders) or consent (if approved by written action) of holders of

7

more than 50% of the outstanding principal amount of the debt securities of that series.

However, holders may approve, by vote or consent through one of three modification methods, any proposed modification by Colombia that would do any of the following (such subjects referred to as “reserve matters”):

• change the date on which any amount is payable on the debt securities;

• reduce the principal amount (other than in accordance with the express terms of the debt securities and the indenture) of the debt securities;

• reduce the interest rate on the debt securities;

• change the method used to calculate any amount payable on the debt securities (other than in accordance with the express terms of the debt securities and the indenture);

• change the currency or place of payment of any amount payable on the debt securities;

• modify Colombia’s obligation to make any payments on the debt securities (including any redemption price therefor);

• change the identity of the obligor under the debt securities;

• change the definition of “outstanding debt securities” or the percentage of affirmative votes or written consents, as the case may be, required to make a “reserve matter modification;”

• change the definition of “uniformly applicable” or “reserve matter modification;”

• authorize the trustee, on behalf of all holders of the debt securities, to exchange or substitute all the debt securities for, or convert all the debt securities into, other obligations or securities of Colombia or any other person; or

• change the legal ranking, governing law, submission to jurisdiction or waiver of immunities provisions of the terms of the debt securities.

A change to a reserve matter, including the payment terms of any series of debt securities, can be made without your consent, as long as the change is approved, pursuant to one of the three following modification methods, by vote or consent by:

• the holders of more than 75% of the aggregate principal amount of the outstanding debt securities of a series affected by the proposed modification;

• where such proposed modification would affect the outstanding debt securities of two or more series, the holders of more than 75% of the aggregate principal amount of outstanding debt securities of all of the series affected by the proposed modification, taken in the aggregate, if certain “uniformly applicable” requirements are met; or

• where such proposed modification would affect the outstanding debt securities of two or more series, whether or not the “uniformly applicable” requirements are met, the holders of more than 66 ²/₃% of the aggregate principal amount of the outstanding debt securities of all of the series affected by the proposed modification, taken in the aggregate, and the holders of more than 50% of the aggregate principal amount of the outstanding debt securities of each series affected by the modification, taken individually.

With respect to any such proposed modification that would affect the outstanding debt securities of two or more series, it is understood that any such modification that does not meet the “uniformly applicable” requirements must be effected pursuant to the third bullet above and such modification that is “uniformly applicable” may be effected pursuant to either the second or third bullet, at Colombia’s option.

“Uniformly applicable” means a modification by which holders of debt securities of all series affected by that modification are invited to exchange, convert or substitute their debt securities on the same terms for (x) the same new instruments or other consideration or (y) new instruments or other consideration from an identical menu of instruments or other consideration. It

8

is understood that a modification will not be considered to be uniformly applicable if each exchanging, converting or substituting holder of debt securities of any series affected by that modification is not offered the same amount of consideration per amount of principal, the same amount of consideration per amount of interest accrued but unpaid and the same amount of consideration per amount of past due interest, respectively, as that offered to each other exchanging, converting or substituting holder of debt securities of any series affected by that modification (or, where a menu of instruments or other consideration is offered, each exchanging, converting or substituting holder of debt securities of any series affected by that modification is not offered the same amount of consideration per amount of principal, the same amount of consideration per amount of interest accrued but unpaid and the same amount of consideration per amount of past due interest, respectively, as that offered to each other exchanging, converting or substituting holder of debt securities of any series affected by that modification electing the same option under such menu of instruments).

Colombia may select, in its discretion, any modification method for a reserve matter modification in accordance with the indenture and to designate which series of debt securities will be included for approval in the aggregate of modifications affecting two or more series of debt securities. Any selection of a modification method or designation of series to be included will be final for the purpose of that vote or consent solicitation. If any one or more debt securities issued under the indenture prior to September 8, 2015 are included in a proposed modification affecting two or more series of debt securities under the indenture that seeks holder approval pursuant to a single aggregated vote, that modification will be uniformly applicable (as described above) to all such series, regardless of when they were issued.

Before soliciting any consent or vote of any holder of debt securities for any change to a reserve matter, Colombia will provide the following information to the trustee for distribution to the holders of debt securities of any series that would be affected by the proposed modification:

• a description of Colombia’s economic and financial circumstances, that are in Colombia’s opinion relevant to the request

for the proposed modification, a description of Colombia’s existing debts and a description of its broad policy reform program and provisional macroeconomic outlook;

• if Colombia shall at the time have entered into an arrangement for financial assistance with multilateral and/or other major creditors or creditor groups and/or an agreement with any such creditors regarding debt relief, (x) a description of any such arrangement or agreement and (y) where permitted under the information disclosure policies of the multilateral or other creditors, as applicable, a copy of the arrangement or agreement;

• a description of Colombia’s proposed treatment of external debt instruments that are not affected by the proposed modification and its intentions with respect to any other major creditor groups; and

• if Colombia is then seeking any reserve matter modification affecting any other series of debt securities, a description of that proposed modification.

For purposes of determining whether the required percentage of holders of the debt securities of a series has approved any amendment, modification or change to, or waiver of, the debt securities or the indenture, or whether the required percentage of holders has delivered a notice of acceleration of the debt securities of that series, debt securities will be disregarded and deemed not to be outstanding and may not be counted in a vote or consent solicitation for or against a proposed modification if on the record date for the proposed modification or other action or instruction hereunder, the debt security is held by Colombia or by a public sector instrumentality, or by a corporation, trust or other legal entity that is controlled by Colombia or a public sector instrumentality, except that (x) debt securities held by Colombia or any public sector instrumentality of Colombia or by a corporation, trust or other legal entity that is controlled by Colombia or a public sector instrumentality which have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the satisfaction of the trustee the pledgee’s right so to act with respect to such debt securities and that the pledgee is not

9

Colombia or a public sector instrumentality, and in case of a dispute concerning such right, the advice of counsel shall be full protection in respect of any decision made by the trustee in accordance with such advice and any certificate, statement or opinion of counsel may be based, insofar as it relates to factual matters or information which is in the possession of the trustee, upon the certificate, statement or opinion of or representations by the trustee; and (y) in determining whether the trustee will be protected in relying upon any such action or instructions hereunder, or any notice from holders, only debt securities that a responsible officer of the trustee knows to be so owned or controlled will be so disregarded.

As used in the preceding paragraph, “public sector instrumentality” means any department, ministry or agency of Colombia, and “control” means the power, directly or indirectly, through the ownership of voting securities or other ownership interests, by contract or otherwise, to direct the management of or elect or appoint a majority of the board of directors or other persons performing similar functions in lieu of, or in addition to, the board of directors of that legal entity.

Certain Amendments Not Requiring Holder Consent.

Colombia and the trustee may, without the vote or consent of any holder of debt securities of a series, amend the indenture or the debt securities of the series for the purpose of:

• adding to Colombia’s covenants for the benefit of the holders;

• surrendering any of Colombia’s rights or powers with respect to the debt securities of that series;

• securing the debt securities of that series;

• curing any ambiguity or curing, correcting or supplementing any defective provision in the debt securities of that series or the indenture;

• amending the debt securities of that series or the indenture in any manner that Colombia and the trustee may

determine and that does not materially adversely affect the interests of any holders of the debt securities of that series; or

• correcting a manifest error of a formal, minor or technical nature.

Notices

Notices to the holders of debt securities will be mailed to the addresses of such holders as they appear in the register maintained by the trustee.

Further Issues of Debt Securities

From time to time, Colombia may, without the consent of holders of the debt securities of any series, create and issue additional debt securities with the same terms and conditions as those of the debt securities of that series (or the same except the amount of the first interest payment, the issue date and the issue price), provided, however, that any additional debt securities subsequently issued shall be fungible with the previously outstanding debt securities for U.S. federal income tax purposes. Additional debt securities issued in this manner will be consolidated with and will form a single series with the previously outstanding debt securities of that series.

Warrants

If Colombia issues warrants, it will describe their specific terms in a prospectus supplement. If any warrants are to be offered, Colombia will file a warrant agreement and form of warrant with the SEC. The following description briefly summarizes some of the general terms that will apply to warrants. You should read the applicable prospectus supplement, warrant agreement and form of warrant before making your investment decision.

Colombia may issue warrants separately or together with any debt securities. All warrants will be issued under a warrant agreement to be entered into between Colombia and a bank or trust company, as warrant agent. The applicable prospectus supplement will include some or all of the following specific terms relating to the warrants:

• the initial offering price;

10

• the currency you must use to purchase the warrants;

• the title and terms of the debt securities or other consideration that you will receive on exercise of the warrants;

• the principal amount of debt securities or amount of other consideration that you will receive on exercise of the warrants;

• the exercise price or ratio;

• the procedures for, and conditions to the exercise of, the warrants;

• the date or dates on which the right to exercise the warrants shall commence and expire;

• whether and under what conditions Colombia may terminate or cancel the warrants;

• the title and terms of any debt securities issued with the warrants and the amount of debt securities issued with each warrant;

• the date, if any, on and after which the warrants and any debt securities issued with such warrants will trade separately;

• the form of the warrants (global or certificated and registered or bearer), whether they will be exchangeable between such forms and, if registered, where they may be transferred and exchanged;

• the identity of the warrant agent;

• any special U.S. federal income tax considerations; and

• any other terms of such warrants.

Global Securities

DTC, Euroclear and Clearstream, Luxembourg are under no obligation to perform or continue to perform the procedures described below and they may modify or discontinue them at any time. None of Colombia, the trustee or any underwriter of

securities named in a prospectus supplement will be responsible for DTC’s, Euroclear’s or Clearstream, Luxembourg’s performance of their obligations under their rules and procedures. Additionally, none of Colombia, the trustee or any underwriter of securities named in a prospectus supplement will be responsible for the performance by direct or indirect participants of their obligations under their rules and procedures.

Colombia may issue the debt securities or warrants in the form of one or more global securities, the ownership and transfer of which are recorded in computerized book-entry accounts, eliminating the need for physical movement of securities.

When Colombia issues global securities, it will deposit the applicable security with a clearing system. The global security will be registered in the name of the clearing system or its nominee or common depositary. Unless a global security is exchanged for physical securities, as discussed below under “Description of the Securities—Certificated Securities,” it may not be transferred, except as a whole among the clearing system, its nominees or common depositaries and their successors. Clearing systems include The Depository Trust Company, known as DTC, in the United States, and Euroclear and Clearstream, Luxembourg, in Europe.

Clearing systems process the clearance and settlement of global notes for their direct participants. A “direct participant” is a bank or financial institution that has an account with a clearing system. The clearing systems act only on behalf of their direct participants, who in turn act on behalf of indirect participants. An “indirect participant” is a bank or financial institution that gains access to a clearing system by clearing through or maintaining a relationship with a direct participant. Euroclear and Clearstream, Luxembourg are connected to each other by a direct link and participate in DTC through their New York depositaries, which act as links between the clearing systems. These arrangements permit you to hold global securities through participants in any of these systems, subject to applicable securities laws.

Ownership of Book-Entry Securities

If you wish to purchase global securities, you must either be a direct participant or make your

11

purchase through a direct or indirect participant. Investors who purchase global securities will hold them in an account at the bank or financial institution acting as their direct or indirect participant. Holding securities in this way is called holding in “street name.”

When you hold securities in street name, you must rely on the procedures of the institutions through which you hold your securities to exercise any of the rights granted to holders. This is because the legal obligations of Colombia and the trustee run only to the registered owner of the global security, which will be the clearing system or its nominee or common depositary. For example, once Colombia and the trustee make a payment to the registered holder of a global security, they will no longer be liable for the payment, even if you do not receive it. In practice, the clearing systems will pass along any payments or notices they receive from Colombia to their participants, which will pass along the payments to you. In addition, if you desire to take any action which a holder of the global security is entitled to take, then the clearing system would authorize the participant through which you hold your global securities to take such action, and the participant would then either authorize you to take the action or would act for you on your instructions.

The transactions between you, the participants and the clearing systems will be governed by customer agreements, customary practices and applicable laws and regulations, and not by any legal obligation of Colombia or the trustee.

As an owner of securities represented by a global security, you will also be subject to the following restrictions:

• you will not be entitled to (a) receive physical delivery of the securities in certificated form or (b) have any of the securities registered in your name except under the circumstances described below under “Description of the Securities—Certificated Securities;”

• you may not be able to transfer or sell your securities to some insurance companies and other institutions that are required by law to own their securities in certificated form;

• you may not be able to pledge your securities in circumstances where certificates must be

physically delivered to the creditor or the beneficiary of the pledge in order for the pledge to be effective; and

• clearing systems require that global securities be purchased and sold within their systems using same-day funds, for example by wire transfer.

Cross-Market Transfer, Clearance and Settlement

The following description reflects Colombia’s understanding of the current rules and procedures of DTC, Euroclear and Clearstream, Luxembourg relating to cross-market trades in global securities. These systems could change their rules and procedures at any time, and Colombia takes no responsibility for their actions or the accuracy of this description.

It is important for you to establish at the time of the trade where both the purchaser’s and seller’s accounts are located to ensure that settlement can be made on the desired value date, i.e., the date specified by the purchaser and seller on which the price of the securities is fixed.

When global securities are to be transferred from a DTC seller to a Euroclear or Clearstream, Luxembourg purchaser, the purchaser must first send instructions to Euroclear or Clearstream, Luxembourg through a participant at least one business day before the settlement date. Euroclear or Clearstream, Luxembourg will then instruct its New York depositary to receive the securities and make payment for them. On the settlement date, the New York depositary will make payment to the DTC participant through which the seller holds its securities, which will make payment to the seller, and the securities will be credited to the New York depositary’s account. After settlement has been completed, Euroclear or Clearstream, Luxembourg will credit the securities to the account of the participant through which the purchaser is acting. This securities credit will appear the next day European time after the settlement date, but will be back-valued to the value date, which will be the preceding day if settlement occurs in New York. If settlement is not completed on the intended value date, the securities credit and cash debit will instead be valued at the actual settlement date.

12

A participant in Euroclear or Clearstream, Luxembourg, acting for the account of a purchaser of global securities, will need to make funds available to Euroclear or Clearstream, Luxembourg in order to pay for the securities on the value date. The most direct way of doing this is for the participant to preposition funds, i.e. have funds in place at Euroclear or Clearstream, Luxembourg before the value date, either from cash on hand or existing lines of credit. The participant may require the purchaser to follow these same procedures.

When global securities are to be transferred from a Euroclear or Clearstream, Luxembourg seller to a DTC purchaser, the seller must first send instructions to and preposition the securities with Euroclear or Clearstream, Luxembourg through a participant at least one business day before the settlement date. Euroclear or Clearstream, Luxembourg will then instruct its New York depositary to credit the global securities to the account of the DTC participant through which the purchaser is acting and to receive payment in exchange. The payment will be credited to the account of the Euroclear or Clearstream, Luxembourg participant through which the seller is acting on the following day, but the receipt of the cash proceeds will be back-valued to the value date which will be the preceding day if settlement occurs in New York. If settlement is not completed on the intended value date, the receipt of the cash proceeds and securities debit will instead be valued at the actual settlement date.

Certificated Securities

Colombia will only issue securities in certificated form in exchange for a global security if:

• the depositary notifies Colombia that it is unwilling or unable to continue as depositary, is ineligible to act as depositary or, in the case of DTC, ceases to be a clearing agency registered under the U.S. Securities Exchange Act of 1934 and Colombia does not appoint a successor depositary or clearing agency within 90 days;

• the trustee has instituted or has been directed to institute any judicial proceeding to enforce the rights of the holders under the debt securities and has been advised by its legal counsel that it

should obtain possession of the securities for the proceeding; or

• Colombia elects not to have the securities of a series represented by a global security or securities.

In any of these cases, unless otherwise provided in the prospectus supplement for an offering, Colombia and the trustee will issue certificated securities:

• registered in the name of each holder;

• without interest coupons; and

• in the same authorized denominations as the global securities.

The certificated securities will initially be registered in the names and denominations requested by the depositary. You may transfer or exchange registered certificated securities by presenting them at the corporate trust office of the trustee. When you surrender a registered certificated security for transfer or exchange, the trustee will authenticate and deliver to you or the transferee a security or securities of the appropriate form and denomination and of the same aggregate principal amount as the security you are surrendering. You will not be charged a fee for the registration of transfers or exchanges of certificated securities. However, you may be charged for any stamp, tax or other governmental charge associated with the transfer, exchange or registration. Colombia, the trustee and any other agent of Colombia may treat the person in whose name any certificated security is registered as the legal owner of such security for all purposes.

If any registered certificated security becomes mutilated, destroyed, stolen or lost, you can have it replaced by delivering the security or the evidence of its loss, theft or destruction to the trustee. Colombia and the trustee may require you to sign an indemnity under which you agree to pay Colombia, the trustee and any agent for any losses they may suffer relating to the security that was mutilated, destroyed, stolen or lost. Colombia and the trustee may also require you to present other documents or proof.

After you deliver these documents, if neither Colombia nor the trustee has notice that a bona fide purchaser has acquired the security you are exchanging, Colombia will execute, and the trustee

13

will authenticate and deliver to you, a substitute security with the same terms as the security you are exchanging. You will be required to pay all expenses and reasonable charges associated with the replacement of the mutilated, destroyed, stolen or lost security.

If a security presented for replacement has become payable, Colombia in its discretion may pay the amounts due on the security in lieu of issuing a new security.

Governing Law

The indenture and the securities will be governed by and interpreted in accordance with the laws of the State of New York unless otherwise specified in any series of debt securities; provided, that all matters related to the consent of holders and any modifications to the indenture or the debt securities will always be governed by and construed in accordance with the law of the State of New York; provided, further, that the laws of Colombia will govern all matters relating to authorization and execution by Colombia.

Jurisdiction; Enforceability of Judgments

Colombia is a foreign sovereign. It may, therefore, be difficult for investors to obtain or enforce judgments against Colombia.

Colombia will appoint the Consul General of Colombia in The City of New York and his or her successors from time to time as its process agent for any action based on the debt securities or warrants of a series instituted in any state or federal court in the Borough of Manhattan, The City of New York.

Colombia will irrevocably submit to the exclusive jurisdiction of any state or federal court in the Borough of Manhattan, The City of New York and the courts of Colombia that sit in Bogota D.C. in respect of any action arising out of or based on the securities. Colombia will also irrevocably waive any objection to the venue of any of these courts in an action of that type. Holders of the securities may, however, be precluded from initiating actions arising out of or based on the securities in courts other than

those mentioned above. Colombia will, to the fullest extent permitted by law, irrevocably waive and agree not to plead any immunity from the jurisdiction of any of the above courts in any action based upon the securities. This waiver covers Colombia’s sovereign immunity and immunity from prejudgment attachment, post judgment attachment and execution, except as provided under (i) Articles 192, 195, 298 and 299 of Law 1437 of 2011 (Código de Procedimiento Administrativo y de lo Contencioso Administrativo); and (ii) Articles 593, 594 and 595 et al of Law 1564 of 2012 (Código General del Proceso) and Article 19 of Decree 111 of January 15, 1996, pursuant to which the revenues, assets and property of the Republic located in the Republic are not subject to execution, set-off or attachment.

Nevertheless, Colombia reserves the right to plead sovereign immunity under the U.S. Foreign Sovereign Immunities Act of 1976, as amended (the “Immunities Act”), in actions brought against it under the United States federal securities laws or any state securities laws. Colombia’s appointment of its process agent will not extend to these actions. Without Colombia’s waiver of immunity, you will not be able to obtain a United States judgment against Colombia unless the court determines that Colombia is not entitled under the Immunities Act to sovereign immunity in such action. In addition, execution upon property of Colombia located in the United States to enforce a judgment obtained under the Immunities Act may not be possible except in the limited circumstances specified in the Immunities Act.

Even if you are able to obtain a judgment against Colombia in an action under the United States federal securities laws or any state securities laws, you might not be able to enforce it in Colombia. Your ability to enforce foreign judgments in Colombia is dependent, among other factors, on such judgments not violating the principles of Colombian public order. The Head or Acting Head of the Legal Affairs Group of the General Directorate of Public Credit and National Treasury of the Ministry of Finance and Public Credit of Colombia will render an opinion on this matter in connection with each issuance of securities and/or warrants hereunder.

14

Provision in National Budget

Colombia recognizes that amounts due under the securities must be paid out of appropriations provided in the national budget. Colombia will undertake that it will annually take all necessary and appropriate actions to provide for the due inclusion of such amounts in the national budget and to ensure timely payment of all amounts due.

Contracts with Colombia

In accordance with Colombian law, by purchasing the securities, you will be deemed to have waived any right to petition for diplomatic claims to be asserted by your government against Colombia with respect to your rights as a holder under the indenture and the securities, except in the case of denial of justice.

TAXATION

The following discussion summarizes certain United States federal and Colombian federal tax considerations that may be relevant to you if you invest in the debt securities. This summary is based on laws, regulations, rulings and decisions now in effect in the United States and on laws and regulations now in effect in Colombia and may change. Any change could apply retroactively and could affect the continued validity of this summary.

This summary does not describe all of the tax considerations that may be relevant to you or your situation, particularly if you are subject to special tax rules. You should consult your tax advisor about the tax consequences of holding debt securities, including the relevance to your particular situation of the considerations discussed below, as well as of state, local and other tax laws.

Colombian Taxation

Under current Colombian law, payments of principal and interest on the debt securities are not subject to Colombian income or withholding tax, provided that the holder of the debt securities is not a Colombian resident and is not domiciled in

Colombia. In addition, gains realized on the sale or other disposition of the debt securities will not be subject to Colombian income or withholding tax, provided that the holder of the debt securities is not a Colombian resident and is not domiciled in Colombia. There are no Colombian transfer, inheritance, gift or succession taxes applicable to the debt securities.

United States Federal Taxation

The following discussion describes the material U.S. federal income tax consequences of your purchase, ownership and disposition of a debt security. The following discussion does not describe any material U.S. federal income tax consequences attributable to investing in warrants. The discussion is based on the provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, existing and proposed regulations promulgated by the U.S. Department of the Treasury under the Code (the “Treasury Regulations”), published rulings and judicial decisions interpreting the Code as of the date that this prospectus was issued. These laws and authorities may be repealed, revoked or modified, possibly with retroactive effect. No assurances can be given that any changes in these laws or authorities will not affect the accuracy of the discussion below. This discussion does not cover any U.S. state or local, or non-U.S. tax issues, nor does it cover issues under the U.S. federal estate or gift tax laws.

Colombia has not sought any ruling from the U.S. Internal Revenue Service (the “IRS”) with respect to the statements made and the conclusions reached in this discussion, and there can be no assurance that the IRS will agree with all of such statements and conclusions. A different treatment from that described below could adversely affect the amount, timing, and character of income, gain or loss in respect of an investment in the debt securities.

This discussion deals only with holders that (i) hold a debt security as a capital asset for U.S. federal income tax purposes (generally, property held for investment), (ii) were initial purchasers of that debt security, and (iii) acquired the debt security at its issue price. This discussion does not purport to deal with all aspects of U.S. federal income taxation that may be relevant to a particular holder in light of

15

the holder’s circumstances (for example, persons subject to the alternative minimum tax provisions of the Code). This discussion also assumes that you are not subject to any special U.S. federal income tax rules, including, among others, the special tax rules applicable to:

• persons subject to special tax accounting rules under Section 451(b) of the Code;

• dealers in securities or currencies;

• securities traders using a mark-to-market accounting method;

• banks or life insurance companies;

• persons subject to the alternative minimum tax;

• United States expatriates;

• persons that purchase or sell debt securities as part of a wash sale for tax purposes;

• persons that purchase or sell debt securities as part of a hedging transaction or as a position in a straddle or conversion transaction;

• partnerships or other entities classified as partnerships for U.S. federal income tax purposes, or persons holding debt securities through partnerships or other pass-through entities;

• U.S. Holders (as defined below) that do not use the U.S. dollar as their functional currency; or

• tax-exempt organizations.

If any of these assumptions are not correct in your case, the purchase, ownership or disposition of a debt security may have U.S. federal income tax consequences to you that differ from, or are not covered in, this discussion.

If a partnership (including any entity classified as a partnership for U.S. federal income tax purposes) is a beneficial owner of a debt security, the tax treatment of a partner in that partnership generally will depend on the status of the partner and the activities of the partnership. Holders of debt

securities that are partnerships and partners in those partnerships should consult their own tax advisor regarding the U.S. federal income tax consequences of purchase, ownership and disposition of the debt securities.

Any special material U.S. federal income tax consequences not otherwise discussed herein, that are applicable to any particular issued debt securities, or that are applicable to any particular issued warrants, will be discussed in the applicable prospectus supplement, as necessary.

You should consult your own tax advisor concerning the U.S. federal, state, local, non-U.S. and other tax consequences to you of the purchase, ownership or disposition of a debt security.

U.S. Holders

This section applies to you if you are a “U.S. Holder,” meaning that you are the beneficial owner of a debt security and you are:

• an individual citizen or resident of the United States for U.S. federal income tax purposes;

• a corporation (or other entity classified as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any state thereof or the District of Columbia;

• an estate whose income is subject to U.S. federal income taxation regardless of its source; or

• a trust (A) if a court within the United States is able to exercise primary jurisdiction over your administration and one or more “United States persons” as defined in the Code (each a “U.S. Person”) have authority to control all your substantial decisions, or (B) that was in existence on August 20, 1996 and has made a valid election under the Treasury Regulations to be treated as a U.S. trust.

16

If you are not a U.S. Holder, this section does not apply to you and you should refer to “—Non-U.S. Holders” below.

Payments of Interest. Payments or accruals of stated interest on a debt security generally will be taxable to you as ordinary income. If you generally report your taxable income using the accrual method of accounting, you must include payments of interest in your income as they accrue. If you generally report your taxable income using the cash method of accounting, you must include payments of interest in your income when you actually or constructively receive them.

You must include any tax withheld from the interest payment as ordinary income even though you do not in fact receive it. You may be entitled to deduct or credit this tax, subject to applicable limits. You will also be required to include in income as interest any additional amounts paid with respect to withholding tax on the debt securities, including withholding tax on payments of such additional amounts. For purposes of the “foreign tax credit” provisions of the Code, interest (including any additional amounts) on a debt security generally will constitute “foreign source income” and will, depending on your circumstances, be categorized as “passive” or “general” category income for purposes of computing the foreign tax credit allowable to you under U.S. federal income tax laws.

Disposition of Debt Securities. If you sell or otherwise dispose of a debt security, you generally will recognize a gain or loss equal to the difference between your “amount realized” and your “adjusted tax basis” in the debt security. Your “amount realized” will be the value of what you receive for selling or otherwise disposing of the debt security, other than amounts that represent interest that is due to you but that has not yet been paid (which will be taxed to you as ordinary interest income to the extent not previously included in income). Your “adjusted tax basis” in the debt security will generally equal the amount that you paid for the debt security.

Gain or loss from the sale or other disposition of a debt security generally will be capital gain or loss, and will be long-term capital gain or loss if at the time you sell or dispose of the debt security, you have held the debt security for more than one year, or

will be short-term capital gain or loss if you have held the debt security for one year or less. Under the current U.S. federal income tax law, long-term capital gains of non-corporate taxpayers may be taxed at lower rates than items of ordinary income. Your ability to offset capital losses against ordinary income is limited. Any capital gains or losses that arise when you sell or dispose of a debt security generally will be treated as U.S. source income, or loss allocable to U.S. source income, for purposes of the foreign tax credit provisions of the Code.

Medicare Tax. A U.S. Holder that is an individual or estate, or a trust that does not fall into a special class of trusts that is exempt from such tax, will be subject to a 3.8 percent Medicare tax on the lesser of (i) the U.S. Holder’s “net investment income” (or, in the case of an estate or trust, the “undistributed net investment income”) for the relevant taxable year and (ii) the excess of the U.S. Holder’s modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000, depending on the individual’s circumstances). A U.S. Holder’s net investment income generally will include its interest income and its net gains from the disposition of the debt securities, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). If you are an individual, estate or trust, you are urged to consult your own tax advisor regarding the applicability of the Medicare tax to your income and gains in respect of your investment in the debt securities.

Information with Respect to Foreign Financial Assets. Owners of “specified foreign financial assets” with an aggregate value in excess of $50,000 on the last day of the taxable year, or $75,000 at any time during the taxable year generally may be required to file information reports with respect to such assets with their U.S. federal income tax returns. Depending on your circumstances, higher threshold amounts may apply. “Specified foreign financial assets” include any financial accounts maintained by foreign financial institutions, as well as any of the following, but only if they are held for investment and not held in accounts maintained by financial institutions: (i) stocks and securities issued by non-U.S. persons,

17

(ii) financial instruments and contracts that have non-U.S. issuers or counterparties, and (iii) interests in non-U.S. entities. The debt securities may be treated as specified foreign financial assets and you may be subject to this information reporting regime. Failure to file information reports may subject you to penalties. You should consult your own tax advisor regarding your obligation to file information reports with respect to the debt securities.

Non-U.S. Holders

This section applies to you if you are a “Non-U.S. Holder,” meaning that you are a beneficial owner of a debt security and are not a partnership for U.S. federal income tax purposes or a “U.S. Holder” as defined above.

Payments of Interest. Subject to the discussion of backup withholding below, you generally will not be subject to U.S. federal income tax, including withholding tax, on interest that you receive on a debt security unless you are engaged in a trade or business in the United States and the interest on the debt security is treated for U.S. federal income tax purposes as “effectively connected” to that trade or business (or, if an income tax treaty applies, the interest is attributable to a permanent establishment or fixed place of business maintained by you within the United States). If you are engaged in a U.S. trade or business and the interest income is deemed to be effectively connected to that trade or business, you generally will be subject to U.S. federal income tax on that interest in the same manner as if you were a U.S. Holder. In addition, if you are a non-U.S. corporation, your interest income subject to tax in that manner may increase your liability under the U.S. “branch profits tax” currently imposed at a 30% rate (or a lower rate under an applicable tax treaty).

Disposition of Debt Securities. Subject to the backup withholding discussion below, you generally will not be subject to U.S. federal income tax or withholding tax on any capital gain that you realize when you sell or otherwise dispose of a debt security unless:

1. that gain is effectively connected for U.S. federal income tax purposes to any U.S. trade or business you are engaged in (or, if an income tax treaty

applies, the gain is attributable to a permanent establishment or fixed base in the United States); or

2. if you are a nonresident alien individual, you are present in the United States for 183 days or more during the taxable year in which you sell or otherwise dispose of the debt security and either (i) you have a “tax home” (as defined in the Code) in the United States during the taxable year in which you sell or otherwise dispose of the debt security, or (ii) the gain is attributable to any office or other fixed place of business that you maintain in the United States.

If you are a Non-U.S. Holder described under (1) above, you generally will be subject to U.S. federal income tax on such gain in the same manner as a U.S. Holder and, if you are a non-U.S. corporation, you may also be subject to the U.S. branch profits tax as described above. If you are a Non-U.S. Holder described under (2) above, you generally will be subject to a 30% percent tax on the gain derived from the sale or other taxable disposition of a debt security, which may be offset by certain U.S. source capital losses (notwithstanding the fact that you are not considered a U.S. resident for U.S. federal income tax purposes). Any amount attributable to accrued but unpaid interest on a debt security generally will be treated in the same manner as payments of interest made to you, as described above under “—Payments of Interest.”

Backup Withholding and Information Reporting

If you are a U.S. Holder, and unless you prove that you are exempt, information reporting requirements will apply to payments of principal and interest on a debt security to you if such payments are made within the United States. Such payments will be considered made within the United States if transferred to an account maintained in the United States or mailed to a United States address, and the amount is paid by or through a custodian or nominee that is a “U.S. Controlled Person,” as defined below. Backup withholding will apply to such payments of principal and interest if (i) you fail to provide an accurate taxpayer identification number; (ii) you fail

18

to certify that you are not subject to backup withholding; (iii) you are notified by the IRS that you have failed to report all interest and dividend income required to be shown on your U.S. federal income tax returns; or (iv) you fail to demonstrate your eligibility for an exemption.

If you are a Non-U.S. Holder, you generally are exempt from these withholding and reporting requirements (assuming that the gain or income is otherwise exempt from U.S. federal income tax), but you may be required to comply with certification and identification procedures in order to establish your exemption. If you are paid the proceeds of a sale or redemption of a debt security effected at the U.S. office of a broker, you generally will be subject to the information reporting and backup withholding rules. In addition, the information reporting rules will apply to payments of proceeds of a sale or redemption effected at a non-U.S. office of a broker that is a “U.S. Controlled Person,” as defined below, unless the broker has documentary evidence that the holder or beneficial owner is not a U.S. Holder (and has no actual knowledge or reason to know to the contrary) or the holder or beneficial owner otherwise establishes an exemption. A U.S. Controlled Person is:

• a U.S. Person;

• a “controlled foreign corporation” for U.S. federal income tax purposes;

• a non-U.S. person 50% or more of whose gross income is effectively connected with a U.S. trade or business for U.S. federal income tax purposes for a specified three-year period; or

• a non-U.S. partnership in which U.S. Persons hold, at any time during the non-U.S. partnership’s tax year, more than 50% of the income or capital interests or which is engaged in a U.S. trade or business.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to you generally will be allowed as a refund or a credit against your U.S. federal income tax liability as long as you provide the required information to the IRS in a timely manner.
