deposits from this group totaled $11.8 million as of such date. As of September 30, 2019, no related party loans were categorized as nonaccrual, past due, restructured or potential problem loans. We expect to continue to enter into transactions in the ordinary course of business on similar terms with our officers, directors and principal shareholders, as well as their immediate family members and affiliates.

Garcia (BayBoston) and Schutz (Mendon Capital QP LP, Mendon Capital Master Fund Ltd., and Iron Road Multi-Strategy Fund LP) and certain other institutional shareholders. These letter agreements, copies of which are included as Exhibits 10.17 through 10.24 to our Registration Statement on Form S-1 of which this prospectus forms a part, among other things, provide for certain rights which are described in more detail below. In connection with this offering, each of BayBoston, EJF Sidecar Fund, Series LLC — Series E and the entities associated with RMB Capital Management (Iron Road Multi-Strategy Fund LP, Mendon Capital QP LP and Mendon Capital Master Fund Ltd.), or RMB Capital, who we refer to as the institutional investors, have agreed to waive their contractual preemptive and registration rights.
Board Representation and Observer Rights. We have agreed to nominate one person designated by BayBoston to our Board and the Bank Board. The letter agreement providing for this right, dated April 1, 2015, as amended by the letter agreement, dated February 17, 2017, does not provide for termination terms with respect to this appointment right. Currently, Mr. Garcia serves on our Board as the representative of BayBoston.
In addition, in the letter agreement, dated February 17, 2017, we agreed to invite one person designated by EJF Sidecar Fund, Series LLC — Series E to attend all meetings of our Board and the Bank Board and receive copies of all notices, minutes, consents and other materials that we provide to our directors. These board observation rights will continue with respect to EJF Sidecar Fund, Series LLC — Series E for so long as EJF Sidecar Fund, Series LLC — Series E, together with its affiliates, continues to hold 9.9% or more of our issued and outstanding Class A Common Stock on an as-converted basis.
Exchange of Class B Non-Voting Common Stock. We gave the institutional investors the right to exchange shares of our Class B Common Stock for an equal number of our Class A Common Stock if (i) our Board approves the exchange and the exchange would not result in such institutional investor or its affiliates owning greater than 9.9% of our Class A Common Stock or (ii) upon the consummation of (a) a transfer pursuant to a widely distributed public offering, (b) a transfer in which no transferee acquires greater than two percent of our Class A Common Stock, (c) a transfer to a person that beneficially owns greater than 50% of our issued and outstanding Class A Common Stock or (d) a transfer approved by the Federal Reserve.
Contractual Preemptive Rights. Other than transactions involving a change of control, a stock split, dividend, and certain other circumstances, we gave each of these institutional investors the contractual right to purchase its pro rata share of any securities, options or debt that are convertible or exchangeable into our stock for the same price and on the same terms as such securities are offered to others. On the consummation of a firm commitment underwritten public offering of our stock pursuant to a registration statement resulting in gross proceeds to us of at least $25 million, such contractual preemptive rights will terminate. We expect these contractual preemptive rights to terminate in connection with the closing of this offering.
Registration Rights. In connection with the 2017 private offering, we entered into individual Registration Rights Agreements, each dated February 17, 2017, with each of the institutional investors. The
