WHEREAS, the Lease Term expires for the Premises on September 30, 2022 ("Expiration Date"); and,

WHEREAS, the parties desire to further amend and modify the Lease as hereinafter set forth.

NOW, THEREFORE, by mutual agreement of the parties and in consideration of the mutual promises and obligations hereinafter set forth, the Lease and all related documents are hereby amended and modified as follows:

1. The foregoing recitals are true and correct and are incorporated herein by reference.

2. Pursuant to Section 17 of Lease Amendment No. 3, Tenant has satisfied the requirement to reduce its Security Deposit to $500,000 in cash. Notwithstanding the foregoing, Landlord has agreed to accept Tenant's request that the cash Security Deposit be replaced with a Letter of Credit provided it meets the following criteria:

During the remainder of the Lease Term, Tenant will provide to Landlord, a clean, unconditional, irrevocable, payable-at-sight letter of credit, which shall conform, in all material respects to the form attached to the Lease in the stated principal amount of $500,000.00, drawn on a bank chartered in North Carolina and approved by Landlord ("LOC").

The LOC shall name Landlord as its beneficiary and shall remain outstanding until 30 days after the expiration of the Lease Term, including all extensions and renewals. The Letter of Credit must require the bank to provide 60-days advance written notice to Landlord in the event of a pending cancellation or for non-renewal of the Letter of Credit. The Letter of Credit must also allow Landlord to transfer its beneficiary rights in Landlord's sole discretion. If there shall be a monetary event of default under the Lease, in addition to the remedies set forth in Section 11.2 of the Lease, Landlord shall have the right immediately, without further notice, to draw on the LOC in whole or in part at Landlord's sole discretion to reimburse Landlord for the default and all related costs. Notwithstanding the forgoing, Landlord shall provide Tenant the right to cure said monetary default provided such

default is cured within seven business days. Tenant must provide to Landlord a replacement letter of credit in the same amount and with the same terms, and pay to Landlord a nonrefundable fee of $2,500.00 to reimburse Landlord for its costs associated with drawing upon the LOC.
