No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended, and otherwise in accordance with applicable law.  2  Additional Information and Where to Find It  The proposed transaction involving Cincinnati Bell and Hawaiian Telcom will be submitted to Hawaiian Telcom’s stockholders for their consideration. In connection with the proposed transaction involving Cincinnati Bell and Hawaiian Telcom, Cincinnati Bell intends to file with the Securities and Exchange Commission (the “SEC”) a registration statement on Form S-4 (the “Registration Statement”), which will include a prospectus with respect to Cincinnati Bell’s common shares to be issued in the proposed transaction and a proxy statement for Hawaiian Telcom’s stockholders (the “Proxy Statement”) and Hawaiian Telcom will mail the Proxy Statement to its stockholders and file other documents regarding the proposed transaction with the SEC. SECURITY HOLDERS ARE URGED AND ADVISED TO READ ALL RELEVANT MATERIALS FILED WITH THE SEC, INCLUDING THE REGISTRATION STATEMENT AND THE PROXY STATEMENT, CAREFULLY WHEN THEY BECOME AVAILABLE, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT THE PROPOSED TRANSACTION AND RELATED MATTERS. The Registration Statement, the Proxy Statement and other relevant materials (when they become available) and any other documents filed or furnished by Cincinnati Bell or Hawaiian Telcom with the SEC may be obtained free of charge at the SEC’s web site at www.sec.gov. In addition, security holders will be able to obtain free copies of the Registration Statement and the Proxy Statement from Cincinnati Bell by going to its investor relations page on its corporate web site at www.cincinnatibell.com and from Hawaiian Telcom by going to its investor relations page on its corporate web site at www.hawaiiantel.com.  Participants in the Solicitation  Cincinnati Bell, Hawaiian Telcom, their respective directors and certain of their respective executive officers and employees may be deemed to be participants in the solicitation of proxies in connection with the proposed transaction involving Cincinnati Bell and Hawaiian Telcom. Information about Cincinnati Bell’s directors and executive officers is set forth in its definitive proxy statement for its 2017 Annual Meeting of Shareholders, which was filed with the SEC on March 24, 2017 and information about Hawaiian Telcom’s directors and executive officers is set forth in its definitive proxy statement for its 2017 Annual Meeting of Stockholders, which was filed with the SEC on March 14, 2017.

Additional information regarding the interests of participants in the solicitation of proxies in connection with the proposed transaction will be included in the Registration Statement, the Proxy Statement and other relevant materials Cincinnati Bell and Hawaiian Telcom intend to file with the SEC.  This presentation contains information about adjusted earnings before interest, taxes, depreciation and amortization (Adjusted EBITDA of Cincinnati Bell). This non-GAAP financial measure is used by Cincinnati Bell management when evaluating results of operations and cash flows. Management believes this measure also provides users of the financial statements with additional and useful comparisons of current results of operations and cash flows with past and future periods. Non-GAAP financial measures should not be construed as being more important than comparable GAAP measures. The company defines Adjusted EBITDA as GAAP operating income plus depreciation, amortization, restructuring and severance related charges, (gain) loss on sale or disposal of assets, transaction costs, curtailment (gain) loss, asset impairments, components of pension and other retirement plan costs (including interest costs, asset returns, and amortization of actuarial gains and losses), and other special items. Management believes that Adjusted EBITDA provides a useful measure of operational performance. Adjusted EBITDA should not be considered as an alternative to comparable GAAP measures of profitability and may not be comparable with the measures as defined by other companies.  Non-GAAP Financial Measures 

 This communication may contain “forward-looking” statements, as defined in federal securities laws including the Private Securities Litigation Reform Act of 1995, which are based on our current expectations, estimates, forecasts and projections. Statements that are not historical facts, including statements about the beliefs, expectations and future plans and strategies of the Company, are forward-looking statements. Actual results may differ materially from those expressed in any forward-looking statements. The following important factors, among other things, could cause or contribute to actual results being materially and adversely different from those described or implied by such forward-looking statements including, but not limited to: those discussed in this communication; we operate in highly competitive industries, and customers may not continue to purchase products or services, which would result in reduced revenue and loss of market share; we may be unable to grow our revenues and cash flows despite the initiatives we have implemented; failure to anticipate the need for and introduce new products and services or to compete with new technologies may compromise our success in the telecommunications industry; our access lines, which generate a significant portion of our cash flows and profits, are decreasing in number and if we continue to experience access line losses similar to the past several years, our revenues, earnings and cash flows from operations may be adversely impacted; our failure to meet performance standards under our agreements could result in customers terminating their relationships with us or customers being entitled to receive financial compensation, which would lead to reduced revenues and/or increased costs; we generate a substantial portion of our revenue by serving a limited geographic area; a large customer accounts for a significant portion of our revenues and accounts receivable and the loss or significant reduction in business from this customer would cause operating revenues to decline and could negatively impact profitability and cash flows; maintaining our telecommunications networks requires significant capital expenditures, and our inability or failure to maintain our telecommunications networks could have a material impact on our market share and ability to generate revenue; increases in broadband usage may cause network capacity limitations, resulting in service disruptions or reduced capacity for customers; we may be liable for material that content providers distribute on our networks; cyber attacks or other breaches of network or other information technology security could have an adverse effect on our business; natural disasters, terrorists acts or acts of war could cause damage to our infrastructure and result in significant disruptions to our operations; the regulation of our businesses by federal and state authorities may, among other things, place us at a competitive disadvantage, restrict our ability to price our products and services and threaten our operating licenses; we depend on a number of third party providers, and the loss of, or problems with, one or more of these providers may impede our growth or cause us to lose customers; a failure of back-office information technology systems could adversely affect our results of operations and financial condition; if we fail to extend or renegotiate our collective bargaining agreements with our labor union when they expire or if our unionized employees were to engage in a strike or other work stoppage, our business and operating results could be materially harmed; the loss of any of the senior management team or attrition among key sales associates could adversely affect our business, financial condition, results of operations and cash flows; our debt could limit our ability to fund operations, raise additional capital, and fulfill our obligations, which, in turn, would have a material adverse effect on our businesses and prospects generally; our indebtedness imposes significant restrictions on us; we depend on our loans and credit facilities to provide for our short-term financing requirements in excess of amounts generated by operations, and the availability of those funds may be reduced or limited; the servicing of our indebtedness is dependent on our ability to generate cash, which could be impacted by many factors beyond our control; we depend on the receipt of dividends or other intercompany transfers from our subsidiaries and investments; the trading price of our common shares may be volatile, and the value of an investment in our common shares may decline; the uncertain economic environment, including uncertainty in the U.S. and world securities markets, could impact our business and financial condition; our future cash flows could be adversely affected if it is unable to fully realize our deferred tax assets; adverse changes in the value of assets or obligations associated with our employee benefit plans could negatively impact shareowners’ deficit and liquidity; third parties may claim that we are infringing upon their intellectual property, and we could suffer significant litigation or licensing expenses or be prevented from selling products; third parties may infringe upon our intellectual property, and we may expend significant resources enforcing our rights or suffer competitive injury; we could be subject to a significant amount of litigation, which could require us to pay significant damages or settlements; we could incur significant costs resulting from complying with, or potential violations of, environmental, health and human safety laws; the timing and likelihood of completion of our proposed acquisitions of Hawaiian Telcom and OnX, including the timing, receipt and terms and conditions of any required governmental and regulatory approvals for the proposed transactions that could reduce anticipated benefits or cause the parties to abandon the transactions; the possibility that Hawaiian Telcom’s stockholders may not approve the proposed merger; the possibility that competing offers or acquisition proposals for Hawaiian Telcom will be made; the occurrence of any event, change or other circumstance that could give rise to the termination of the proposed transactions; the possibility that the expected synergies and value creation from the proposed transactions will not be realized or will not be realized within the expected time period; the risk that the businesses of the Company and Hawaiian Telcom and OnX will not be integrated successfully; disruption from the proposed transactions making it more difficult to maintain business and operational relationships; the risk that unexpected costs will be incurred; and the possibility that the proposed transactions do not close, including due to the failure to satisfy the closing conditions and the other risks and uncertainties detailed in our filings, including our Form 10-K, with the SEC as well as Hawaiian Telcom’s filings, including its Form 10-K, with the SEC. These forward-looking statements are based on information, plans and estimates as of the date hereof and there may be other factors that may cause our actual results to differ materially from these forward-looking statements. We assume no obligation to update the information contained in this communication except as required by applicable law.  3  Cautionary Note Regarding Forward-Looking Statements
