parties thereto to terminate, the Senior Secured Notes Indenture, (ii) cancel the Senior Secured Notes and (iii) terminate and release, and will cause the appropriate affiliates of Global Crossing to terminate and release, the guarantees and

sheet attached hereto as Exhibit B. All other documents relating to the GCUK Intercreditor Deed shall be subject to the approval of GCUK, Global Crossing, STT Crossing and STT Hungary in their reasonable discretion.

Crossing Holdings, GCNAH and STT Hungary with respect to the Senior Secured Notes.

conditions reasonably acceptable to STT Crossing and STT Hungary. In connection with such facility, STT Crossing and STT Hungary, as holders of the GCL Notes, intend to negotiate in good faith with the lenders thereunder an intercreditor agreement
relating to such facility. In connection with, and at the time of, the execution of the documentation establishing such facility, Global Crossing will pay STT Crossing and STT Hungary a 175 basis point consent fee, in the aggregate, calculated based

| |  | Fully Diluted Shares Outstanding defined as the sum of (i) common shares outstanding, (ii) shares issuable upon the conversion of any convertible
preferred stock or convertible debt (including the Notes) and (iii) shares underlying vested, exercisable options.  Issuance of Common Equity or any security convertible or exchangeable into Common Equity within six months of the closing date of these Notes and for which an adjustment
under the foregoing provisions shall be required to be made shall be subject to the approval of the members of the Finance Committee who satisfy the NASDAQ independence requirement. This condition (i) shall be in addition to, not in place of,
STTs approval of such issuance and (ii) shall not apply to issuances pursuant to existing securities of the Company (e.g., STTs existing Preferred Stock and the new Notes)  In the event that the Issuer issues or sells Common Equity or any security convertible or exchangeable into Common Equity for cash proceeds
within twenty-four months of the closing date of the Notes at a price less than 83.3% of the Face Amount of Notes at the original issue date of the Notes divided by the shares receivable upon the conversion of the Notes at the original issue date of
the Notes, STT shall have the right but not the obligation to subscribe to a number of shares, at the same terms as agreed between the Issuer and the new investor(s), such that STTs fully-diluted percentage ownership of the Issuer (including
shares underlying the conversion of the Notes) pro-forma for the offering is unchanged.
