Resulting reduced customer service will create customer retention issues and disruption to core franchise - - TrustCo assumes no customer/revenue runoff in pro forma projections Why COHB/HRBT Makes Sense ================================================================================ 1. Accretive to EPS 2. Merger rationale predicated on growth 3. Minimal disruption to customers and core franchise 4. Moderate dividend payout ratio with substantial potential for dividend growth 5. Excess captial provides for tremendous growth opportunities and share repurchases 6. Minimal integration risk/branch overlap 7. "Friendly" merger with similar cultures/philosophies 8. Definitive Agreements in place and all strategic/cultural issues in place 9. Creates $2 billion franchise and a "double dip" opportunity Why TrustCo Offer Does Not Make Sense ================================================================================ 1. Initially dilutive to TRST EPS by 6% 2. Substantial book value dilution to both COHB and HRBT shareholders 3. Predicated on cost savings 4. Substantial disruption to customers/core franchise 5. High dividend payout with low potential for growth 6. Growth constrained by lack of capital 7. High integration risk/revenue runoff 8. "Hostile" merger with culture clash 9. 11 conditions and terms specified as a condition for merger 10. Fully valued TRST currency trading at takeout value makes "double dip" opportunity unlikely Why the TRST tender will never occur and how shareholders could lose ================================================================================ - - Tender of enough shares of COHB/HRBT stock so that, after completion of the offer, TRST owns at least a majority of the shares of COHB stock (on a fully diluted basis) - - Stockholders of COHB/HRBT not having approved the merger of COHB/HRBT - - Requires valid termination of the proposed COHB/HRBT merger agreement - - Requires valid termination of the HRBT/COHB option agreement - - Requires execution of a definitive merger agreement between TRST and COHB or HRBT - - Receipt of all required regulatory approvals - - Effectiveness of registration statement filed by TRST - - TRST being satisfied that the provisions of Section 203 of the Delaware General Corporation Law do not apply to TRST offer and the proposed TRST/COHB or TRST/HRBT merger - - Approval by TRST stockholders of the issuance of TRST stock for either offer - - Receipt of an opinion that the tender offer and subsequent merger constitute a tax-free reorganization - - Absence of any prospective material adverse change in the sole judgment of TRST Why Ambanc Offer Does Not Make Sense ================================================================================ - - Lack of public filing makes deal or pro forma data difficult to ascertain - - AHCI offer ($16.50 in cash) represents deal value of $129.3 million - - As of March 31, 2000 AHCI had assets of $721 million and tangible equity of $68.1 million - - AHCI "core franchise" (thrift only) estimated at approximately $500 million - - Pro forma AHCI/COHB franchise estimated to have a tangible capital ratio of approximately 4% post merger, which presents significant hurdles to regulatory approvals. Further, it appears AHCI is assuming HRBT walks away from its option for no compensation. - - 4.0% post-merger tangible capital ratio would constrain growth opportunities for AHCI - - AHCI 1998 purchase of AFSALA Bancorp is largest acquisition implemented by AHCI - - COHB/HRBT management estimates that AHCI would have to raise proceeds via sale of availble for sale securities at a substantial loss - - AHCI over the past several years has been seeking to be acquired. COHB had preliminary discussion but passed after the completion of due diligence. COHB's last offer in June 2000 was rejected by AHCI.
