13 CFR § 107.760 - How a change in size or activity of a Portfolio Concern affects the Licensee and the Portfolio Concern.
(2) Even after the concern makes a public offering, you may exercise any stock options, warrants, or other rights to purchase Equity Securities which you acquired before the public offering, or fund Commitments you made before the public offering.
(b) Effect of a change in business activity occurring within one year of Licensee's initial Financing—(1) Retention of Investment. Unless you receive SBA's written approval, you may not keep your investment in a Portfolio Concern, small or otherwise, which becomes ineligible by reason of a change in its business activity within one year of your initial investment.
(2) Request for SBA's approval to retain investment. If you request that SBA approve the retention of your investment, your request must include sufficient evidence to demonstrate that the change in business activity was caused by an unforeseen change in circumstances and was not contemplated at the time the Financing was made.
(3) Additional Financing. If SBA approves your request to retain an investment under paragraph (b)(2) of this section, you may provide additional Financing to the Portfolio Concern to the extent necessary to protect against the loss of the amount of your original investment, subject to the overline limitations of § 107.740.
(c) Effect of a change in business activity occurring more than one year after the initial Financing. If a Portfolio Concern becomes ineligible because of a change in business activity more than one year after your initial Financing you may:
(1) Retain your investment; and
(2) Provide additional Financing to the Portfolio Concern to the extent necessary to protect against the loss of the amount of your original investment, subject to the overline limitations of § 107.740.
