Investor Presentation The following investor presentation was furnished by Harbor Acquisition Corporation (“Harbor”) to the Securities and Exchange Commission (“SEC”) as part of a current report on Form 8-K dated April 25, 2007. Harbor intends to hold presentations for certain of its stockholders, as well as other persons who might be interested in purchasing Harbor securities, regarding its proposed acquisition (the “Acquisition”) of Elmet Technologies, Inc. (“Elmet”), as described in Harbor’s previous Form 8-K report dated October 17, 2006 and the amended preliminary proxy statement filed by Harbor with the SEC on April 12, 2007. Ferris, Baker Watts, Incorporated (“FBW"), the managing underwriter of Harbor’s initial public offering consummated in April 2006, is assisting Harbor in these efforts without charge, other than reimbursement of FBW’s out-of-pocket expenses. Harbor and its directors and executive officers and FBW may be deemed to be participants in the solicitation of proxies for the special meeting of Harbor stockholders to be held to approve the Acquisition.  Harbor and the directors and executive officers of Harbor may be deemed to be participating in the solicitation of proxies in respect of the proposed Acquisition. Other information regarding the participants in the proxy solicitation, including the officers and directors of Harbor, and a description of their direct and indirect interests in the Acquisition, by security holdings or otherwise, will be contained in the definitive proxy statement to be filed with the SEC by Harbor and contained in the preliminary proxy statement. Stockholders of Harbor and other interested persons are advised to read, when available, Harbor’s definitive proxy statement in connection with Harbor’s solicitation of proxies for the special meeting because that proxy statement will contain important information. Such persons can also read Harbor’s final prospectus, dated April 27, 2006, for a description of the security holdings of the Harbor officers and directors and their respective interests in the successful consummation of the Acquisition. The definitive proxy statement will be mailed to stockholders as of a record date to be established for voting on the Acquisition. Stockholders will also be able to obtain a copy of the definitive proxy statement, without charge, by directing a request to: Harbor Acquisition Corporation, One Boston Place, Suite 3630, Boston, MA 02108. The preliminary proxy statement, the definitive proxy statement, once available, and the final prospectus can also be obtained, without charge, at the Securities and Exchange Commission's internet site (http://www.sec.gov).

Safe Harbor This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical fact, including, without limitation, statements regarding financial position, business strategy, plans, objectives, operations and industry conditions, are forward-looking statements. Although Harbor believes that the expectations reflected in such forward-looking statements are reasonable, Harbor can give no assurance that such expectations will prove to be correct. Important factors that could cause actual results to differ materially from Harbor expectations (“Cautionary Statements”) include without limitation, the failure of Harbor’s stockholders to approve the Acquisition and the transactions contemplated thereby; the number and percentage of Harbor’s stockholders voting against the Acquisition and electing to exercise their redemption rights; changing interpretations of generally accepted accounting principles; costs associated with continued compliance with government regulations; legislation or regulatory environments, requirements or changes adversely affecting the businesses in which Elmet is engaged; the continued ability of Elmet to successfully execute its business plan involving the proper management of its human resources and assets; demand for the products and services that Elmet provides; continued availability of, and changes in pricing for, raw materials used by Elmet; general economic conditions; geopolitical events and regulatory changes; as well as other relevant risks detailed in Harbor’s filings with the Securities and Exchange Commission. All subsequent written and oral forward-looking statements attributable to Elmet, or persons acting on Harbor’s behalf, are expressly qualified in their entirety by the Cautionary Statements. This presentation contains disclosures of EBITDA for certain periods, which may be deemed to be a non-GAAP financial measure within the meaning of Regulation G promulgated by the Securities and Exchange Commission. As described on page 37, Elmet's EBITDA has been adjusted for certain transaction related expenses and other amounts which Harbor anticipates will not reoccur as part of the future combined operations of Elmet and Harbor. Management believes that Adjusted EBITDA, or earnings before interest, taxes, depreciation and amortization, is an appropriate measure of evaluating operating performance and liquidity, because it reflects the resources available for strategic opportunities including, among others, investments in the business and strategic acquisitions. The disclosure of Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. Adjusted EBITDA should be considered in addition to, and not as a substitute, or superior to, operating income, cash flows, revenue, or other measures of financial performance prepared in accordance with generally accepted accounting principles.

Investment Case to Our Shareholders Since the buyout from Philips Electronics, Elmet has been able to pursue and invest in new high-technology/high-margin business opportunities, which resulted in a: Elmet is just at the beginning of an augmented strategic emphasis on global sales and marketing. Public company peer group is trading at 12.0 times Enterprise Value to EBITDA - a 40% premium to HAC’s negotiated purchase price multiple of 7.3 times. Attractive Growth Opportunity * Compound annual growth rate. See appendix for public comparables. 33% CAGR* of Adjusted EBITDA Harbor Acquisition Corporation Valuation Arbitrage

Investment Case to Our Shareholders (continued) Customers consistently give Elmet the highest marks for service delivery, overall value and solving critical customer needs. The Company creates long-term strategic relationships with its broad customer base. Strong and very agile management team that is committed to building shareholder value through growth of the top and bottom lines. Potential core and adjacent acquisition opportunities each represent 25% to 40% increase in revenue growth within Elmet’s Advanced Enabling Materials business. A November 2006 report from Canaccord Adams on Advanced Enabling Materials companies mentioned Elmet as one of the private companies to watch. Harbor Acquisition Corporation Service Differentiation Elmet Management Elmet as a Platform

Investment Case to Our Shareholders (continued) Elmet provides mission-critical technology products that command above-average margins relative to public company peer group (see Appendix for public comparables). Developing molybdenum and tungsten based technology products requires extensive technical capabilities and intellectual know-how. Elmet is one of the few companies in the world with the fully integrated capability to transform refractory powders into a broad range of highly engineered technology products. * EBITDA Margin means Adjusted EBITDA as a percentage of sales Elmet achieved a 31% Adjusted EBITDA Margin* for FYE 2006 Harbor Acquisition Corporation Technology Company High Barriers to Entry Fully Integrated Capability Elmet’s Advanced Enabling Materials meet specs that similar products made of other materials cannot achieve. Management believes that Elmet’s engineering organization is the best in the industry.
