[1] Operating lease obligations have been reduced by approximately $883,000 to reflect sub-lease income. Certain obligations under leasing arrangements are collateralized by the underlying asset being leased.

[2] Future minimum lease payments include $3.0 million of lease payment obligations for the prior leased Miami distribution center. For the purposes of calculating the minimum lease payments, no reduction was considered for the potential sub-lease income the Company could receive during the remaining lease term. This potential sub-lease income was considered, however, for the purposes of calculating the exit obligation of $50,000 recorded on the balance sheet as of November 30, 2017. Projected income for any executed sub-leases would be used to reduce the amount reported as minimum lease payments.
