Dear Fellow CPBI Owner,
Despite declared intentions to repurchase shares, the
Company has not followed through with meaningful repurchases of its common stock. At an overcapitalized bank, there is no more effective
use of excess capital than repurchasing undervalued shares. We ask for your vote to direct management and the board to sustain meaningful
share repurchases to maximize shareholder value at the Company.

Respectfully,

Megan Parisi
