DESCRIPTION OF SENIOR DEBT SECURITIES
We may issue senior debt securities from time to time in one or more distinct series.
As required by U.S. federal law for all bonds and notes of companies that are publicly offered, the senior debt securities will be governed by a document called an “indenture.” An indenture is a contract between us and a financial institution, in this case, The Bank of New York Mellon formerly known as The Bank of New York, acting as trustee on your behalf, or other trustee we may select. The indenture will be subject to and governed by the Trust Indenture Act of 1939.
We have filed the indenture as an exhibit to our Securities Act of 1933, as amended (“Securities Act”), filings and Exchange Act reports that we have filed with the SEC. See “Where You Can Find More Information” for information on how to obtain a copy of the indenture.
The senior debt securities will be issued under an indenture dated as of June 27, 2001 as supplemented by a first supplemental indenture, dated as of June 27, 2001, each among Quest Diagnostics, as issuer, the Initial Subsidiary Guarantors (as defined therein), as guarantors, and The Bank of New York, as trustee, as further supplemented by a second supplemental indenture, dated as of November 26, 2001, among Quest Diagnostics, the Subsidiary Guarantors (as defined therein) and The Bank of New York, as further supplemented by a third supplemental indenture, dated as of April 4, 2002, among Quest Diagnostics, the Additional Subsidiary Guarantors (as defined therein) and The Bank of New York, as further supplemented by a fourth supplemental indenture, dated as of March 19, 2003, among Quest Diagnostics, the Additional Subsidiary Guarantor (as defined therein) and The Bank of New York, as further supplemented by a fifth supplemental indenture, dated as of April 16, 2004, among Quest Diagnostics, the Additional Subsidiary Guarantor (as defined therein) and The Bank of New York, as further supplemented by a sixth supplemental indenture, dated as of October 31, 2005, among Quest Diagnostics, the Subsidiary Guarantors (as defined therein) and The Bank of New York, as further supplemented by a seventh supplemental indenture, dated as of November 21, 2005, among Quest Diagnostics, the Additional Subsidiary Guarantors (as defined therein) and The Bank of New York, as further supplemented by an eighth supplemental indenture, dated as of July 31, 2006, among Quest Diagnostics, the Additional Subsidiary Guarantors (as defined therein) and The Bank of New York, as further supplemented by the ninth supplemental indenture dated, September 30, 2006, among Quest Diagnostics, the Additional Subsidiary Guarantors (as defined therein) and The Bank of New York, as further supplemented by the tenth supplemental indenture, dated June 22, 2007, among Quest Diagnostics, the Subsidiary Guarantors (as defined therein) and The Bank of New York, as further supplemented by the eleventh supplemental indenture, dated June 22, 2007, among Quest Diagnostics, the Additional Subsidiary Guarantors (as defined therein) and The Bank of New York, as further supplemented by the twelfth supplemental indenture, dated June 25, 2007, among Quest Diagnostics, the Additional Subsidiary Guarantors (as defined therein) and The Bank of New York, as further supplemented by the thirteenth supplemental indenture, dated November 17, 2009, among Quest Diagnostics, the Subsidiary Guarantors (as defined therein) and The Bank of New York Mellon, as further supplemented by the fourteenth supplemental indenture, dated March 24, 2011, among Quest Diagnostics, the Subsidiary Guarantors (as defined therein) and The Bank of New York Mellon, as further supplemented by the fifteenth supplemental indenture, dated November 30, 2011, among Quest Diagnostics, the Additional Subsidiary Guarantors (as defined therein) and The Bank of New York Mellon, as further supplemented by the sixteenth supplemental indenture, dated March 17, 2014, between Quest Diagnostics and The Bank of New York Mellon, as further supplemented by the seventeenth supplemental indenture, dated March 10, 2015, between Quest Diagnostics and The Bank of New York Mellon, as further supplemented by the eighteenth supplemental indenture, dated as of May 26, 2016, between Quest Diagnostics and The Bank of New York Mellon, as further supplemented by the nineteenth supplemental indenture, dated as of March 12, 2019, between Quest Diagnostics and The Bank of New York Mellon, as further supplemented by the twentieth supplemental indenture, dated as of December 16, 2019, between Quest Diagnostics and The Bank of New York Mellon, and as further supplemented by the twenty-first supplemental indenture, dated as of May 13, 2020, between Quest Diagnostics and The Bank of New York Mellon (collectively, as so supplemented, the “Indenture”).
