* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Represents common units of limited partnership interest ("OP Units") in STAG Industrial Operating Partnership, L.P., a Delaware limited partnership (the "Operating Partnership"). The OP Units are redeemable, beginning April 20, 2012, for cash equal to the then current-market value of one share of the common stock of STAG Industrial, Inc. (the "Issuer") or, at the election of the Issuer, for shares of the Issuer's common stock on a one-for-one basis.
(2) The OP Units were issued pursuant to contribution agreements with the Issuer and the Operating Partnership, pursuant to which the reporting person contributed its interests in certain entities that directly or indirectly owned interests in the predecessor management company, to the Operating Partnership and its subsidiaries. The value of the OP Units was $13.00 per share as of the Transaction Date, based on the price of the common stock of the Issuer at the time of the Issuer's initial public offering.
(3) The OP Units are vested as of the date of issuance. The OP Units have no expiration date.
(4) The long-term incentive plan units of the Operating Partnership ("LTIP Units") were granted to the reporting person on April 20, 2011 pursuant to the Issuer's 2011 Equity Incentive Plan.
(5) LTIP Units are subject to forfeiture over a five-year period. Over time, the LTIP Units can achieve full parity with the OP Units for all purposes. If such parity is reached, non-forfeitable LTIP Units may be converted into OP Units and then may be redeemed for cash equal to the then current-market value of one share of the Issuer's common stock or, at the election of the Issuer, for shares of the Issuer's common stock on a one-for-one basis. The LTIP Units do not have an expiration date.
