Global Ship Lease Announces Commencement of Consent Solicitation for 9.875% First Priority Secured Notes due 2022

LONDON, December 13, 2018 – Global Ship Lease, Inc. (NYSE: GSL) (the “Company”) today announced that it is soliciting consents (the “Consent Solicitation”) from holders of its 9.875% First Priority Secured Notes due 2022 (the “Notes”) to approve amendments (the “Proposed Amendments”) to the indenture governing the Notes (the “Indenture”). The Company previously announced, on December 6, 2018, its intent to commence a consent solicitation and a description of the terms thereof, including the Proposed Amendments.

Subject to the terms and conditions set forth in the Consent Solicitation Statement, dated December 13, 2018 (the “Consent Solicitation Statement”), the Company is offering a cash payment (“Consent Fee”) of $7.50 per $1,000 in aggregate principal amount of Notes held by each holder as of the record date set forth in the Consent Solicitation Statement who validly delivers (and does not validly revoke) a duly executed consent at or prior to the Expiration Time. The Company will not be obligated to make any payments if the Company does not receive the Requisite Consents at or prior to the Expiration Time, the Consent Solicitation is terminated for any reason before the Expiration Time or if the other conditions to the Consent Solicitation are not satisfied or waived.

Adoption of the Proposed Amendments requires the consent of the holders of at least a majority of the aggregate principal amount of all outstanding Notes (such consent, the “Requisite Consents”). As of December 13, 2018, the aggregate outstanding principal amount of the Notes was $340,000,000. On December 6, 2018, the Company reached an agreement with beneficial owners of approximately $164.2 million of the principal amount of the Notes, representing approximately 46% of the $360,000,000 aggregate principal amount of Notes outstanding at the time, pursuant to which such holders have agreed to consent with respect to all of their Notes.

The Company anticipates that, promptly after receipt of the Requisite Consents at or prior to 11:59 p.m., New York City time, on December 19, 2018, unless extended by the Company as set forth in the Consent Solicitation Statement (the “Expiration Time”), the Company will give notice to Citibank, N.A., London Branch, as trustee and security agent (the “Trustee”), that the Requisite Consents have been obtained and the Company, the Guarantors and the Trustee will execute and deliver a supplemental indenture with respect to the Indenture (the “Supplemental Indenture” and such time, the “Effective Time”). Pursuant to the terms of the Supplemental Indenture, the Proposed Amendments will become effective at the Effective Time, with retroactive effect as of the date of completion of the transactions contemplated by the Agreement and Plan of Merger

dated October 29, 2018 by and among the Company, Poseidon Containers Holdings LLC, K&T Marine LLC and the other parties thereto, and shall thereafter bind every holder of Notes. Although the Supplemental Indenture will become effective upon execution by the Company, the Guarantors and the Trustee, the Proposed Amendments will not become operative and will have no effect until and unless the payment to consenting holders described above is made in accordance with the terms and conditions set forth in the Consent Solicitation Statement.

The complete terms and conditions of the Consent Solicitation are set forth in the Consent Solicitation Statement. The Company may, in its sole discretion, extend or amend the Consent Solicitation at any time, subject to its agreement with the beneficial owners of the Notes referred to above. A copy of the Consent Solicitation Statement may be obtained from Global Bondholder Services Corporation, the tabulation agent and information agent for the Consent Solicitation, at (866) 807-2200 (toll free) or (212) 430-3774 (collect).

This announcement is for informational purposes only and is neither an offer to sell nor a solicitation of an offer to buy any security. This announcement is also not a solicitation of consents with respect to the Proposed Amendments or any securities. If and when commenced, the Consent Solicitation will be made solely on the terms and subject to the conditions set forth in the Consent Solicitation Statement. The solicitation of consents will not be made in any jurisdiction in which, or to or from any person to or from whom, it is unlawful to make such solicitation under applicable state or foreign securities or “blue sky” laws. No recommendation is being made as to whether holders of Notes should consent to the Proposed Amendments.
