On February 14, 1997, the Company acquired all of the outstanding shares of capital stock of Systems Enhancement Corporation ("Systems Enhancement"), a Missouri corporation, (the "Merger") pursuant to an Agreement and Plan of Merger and Reorganization dated as of February 14, 1997 (the "Merger Agreement"), among the Company, Blue Acquisition Corporation, a Delaware corporation and a wholly- owned subsidiary of the Company, Systems Enhancement and the six stockholders of Systems Enhancement. The Merger was accomplished through an exchange of 480,144 shares of the Company's Common Stock for all outstanding shares of capital stock of Systems Enhancement. The Merger has been accounted for as a pooling-of- interests. The purchase price and terms of the transaction were determined in arms-length negotiations. Systems Enhancement is a developer of network power management products. The Selling Stockholders represented to the Company, in connection with the completion of the Merger, that such Selling Stockholder was acquiring the Shares from the Company without any present intention of effecting a distribution of those Shares. In recognition of the fact, however, that investors may want to be able to sell their shares when they consider appropriate, the Company agreed to file with the Commission a registration statement on Form S-3 (of which this Prospectus is a part) to permit the public sale of the Shares by the Selling Stockholders from time to time and to use reasonable commercial efforts to keep the registration statement effective until the earlier of the sale of the Shares pursuant to the Registration Statement or February 14, 1999 (being the second anniversary of the effective date of the Merger). The Company will prepare and file such amendments and supplements to the registration statement as may be necessary to keep it effective until the earlier of the sale of all Shares pursuant to the registration statement or until February 14, 1999. Notwithstanding the foregoing, each of the Selling Stockholders have entered into an Affiliate Agreement pursuant to which such Selling Stockholder has agreed not to sell any of the Shares until such time as results covering at least 30 days of combined operations of the Company and Systems Enhancement have been published by the Company, in the form of a quarterly or annual earnings report, an effective registration statement filed with the Commission, a report to the Commission on Form 10-K, 10-Q or 8-K, or any other public filing or announcement (including a press release) which includes the combined results of operations. 4 RISK FACTORS In addition to the other information presented in this Prospectus and the information incorporated in this Prospectus by reference, the following risk factors should be considered carefully in evaluating the Company and its business before purchasing the Common Stock offered hereby. Fluctuations in Revenue and Operating Results. The Company's quarterly operating results may fluctuate as a result of a number of factors, including the growth rates in the UPS industry and related industries; timing of orders from, and shipments to, customers; the timing of new product introductions and the market acceptance of those products; increased competition; changes in manufacturing costs; changes in the mix of product sales; inventory risks due to shifts in market demand; component constraints and shortages; risks of nonpayment of accounts receivable; expansion of manufacturing capacity; factors associated with international operations; and changes in world economic conditions. Management of Growth. The Company has experienced, and is currently experiencing, a period of rapid growth which has placed, and could continue to place, a significant strain on the resources of the Company. In order to support the growth of its business, the Company plans to significantly expand its level of operations during 1997. If the Company's management is unable to manage growth effectively, the Company's operating results could be adversely affected. Competition. The Company believes it is one of five global companies providing a full range of UPS products and services in the 0 to 5kva market. The UPS industry, however, is highly competitive on both a worldwide basis and a regional geographic basis. The Company competes, and will continue to compete, with several U.S. and foreign firms with respect to UPS products, both on a worldwide basis and in various geographical regions, and within individual UPS product and application niches. The Company expects competition to increase in the future from existing competitors and a number of companies which may enter the Company's existing or future markets. Increased competition could adversely affect the Company's revenue and profitability through price reductions and loss of market share. The principal competitive factors in the UPS industry are product performance and quality, marketing and access to distribution channels, customer services, product design and price. Some of the Company's current and potential competitors have substantially greater financial, technical, sales and marketing resources than the Company. There can be no assurance that the Company will be able to continue to compete successfully with its existing competitors or will be able to compete successfully with new competitors. Technological Change; New Product Delays; Risks of Product Defects. The market for the Company's products is characterized by rapidly changing technology, evolving industry standards and frequent new product introductions. Current competitors or new market entrants may develop new products with features that could adversely affect the competitive position of the Company's products. There can be no assurance that the Company will be successful in selecting, developing, manufacturing and marketing new products or enhancing its existing products or that the Company will be able to respond effectively to technological changes, new standards or product announcements by competitors. The timely availability of new products and enhancements, and their acceptance by customers are important to the future success of the Company. Delays in such availability or a lack of market acceptance could have an adverse affect on the Company. Although the Company has not experienced material adverse effects resulting from product defects, there can be no assurance that, despite testing internally or by current or potential customers, defects will not be found in products, resulting in loss or delay in market acceptance, which could have a material adverse effect upon the Company's business, operating results and financial condition. 5 Dependence on Key Employees. The Company's success depends to a significant degree upon the continuing contributions of its key management, sales, marketing, research and development and manufacturing personnel, many of whom would be difficult to replace. The Company does not have employment contracts with most of its key personnel. The Company believes that its future success will depend in large part upon its ability to attract and retain highly-skilled hardware and software engineers, and management, sales and marketing personnel. Competition for such personnel is intense, and there can be no assurance that the Company will be successful in attracting and retaining such personnel. Failure to attract and retain key personnel could have a material adverse effect on the Company's business, operating results and financial condition. Foreign Operations; Risk of Currency Fluctuations. The Company manufactures and markets its products worldwide through several foreign subsidiaries and independent agents. The Company's worldwide operations are subject to the risks normally associated with foreign operations including, but not limited to, the disruption of markets, changes in export or import laws, restrictions on currency exchanges, potentially negative tax consequences and the modification or introduction of other governmental policies with potentially adverse effects. International sales (sales to customers outside the United States, both direct and indirect) accounted for approximately 41.7%, 39.7% and 35.5% of the Company's net sales in 1996, 1995 and 1994, respectively. The Company anticipates that international sales will continue to account for a significant portion of revenue. During 1994, the Company began invoicing its customers in Great Britain, France and Germany in their respective local currencies and during the second quarter of 1996 began invoicing its customers in Japan in Yen. To date, the Company does not utilize any rate protection agreements or derivative agreements to hedge any foreign exchange exposure. Accordingly, the Company may be exposed to exchange losses based upon currency exchange rate fluctuations, which losses could have a materially adverse effect on the Company's operating results. Dependence on Sole Source Suppliers. Some components of the Company's products are currently obtained from single sources. There can be no assurance that in the future the Company's suppliers will be able to meet the Company's demand for components in a timely and cost-effective manner. The Company generally purchases these single or limited source components pursuant to purchase orders and has no guaranteed supply arrangements with the suppliers. In addition, the availability of many of these components to the Company is dependent in part on the ability of the Company to provide the suppliers with accurate forecasts of future requirements. The Company has generally been able to obtain adequate supplies of parts and components in a timely manner from existing sources. The Company's operating results and customer relationships could be adversely affected by either an increase in prices for, or an interruption or reduction in supply of, any key components. Uncertainties Regarding Patents and Protection of Proprietary Technology. The Company's success will depend, to a large extent, on its ability to protect its proprietary technology. The Company relies on a combination of contractual rights, trade secrets and copyrights to protect its proprietary rights. Although the Company may apply for patents in the future, there can be no assurance that the Company's intellectual property protection will be sufficient to prevent competitors from developing similar technology. Moreover, in the absence of patent protection, the Company's business may be adversely affected by competitors that independently develop functionally equivalent technology. The Company attempts to ensure that its 6 products and processes do not infringe patents and other proprietary rights, but there can be no assurance that such infringement may not be alleged by third parties in the future. If infringement is alleged, there can be no assurance that the necessary licenses would be available on acceptable terms, if at all, or that the Company would prevail in any such challenge. Integration of Acquired Businesses. The Company consummated its acquisition of Systems Enhancement in February 1997. Systems Enhancement currently operates as a wholly-owned subsidiary of the Company. The Company has limited experience in integrating acquired companies or technologies into its operations. The Company may from time to time pursue the acquisition of other companies, assets, products or technologies. There can be no assurance that products, technologies, distribution channels, key personnel and businesses of Systems Enhancement or any other acquired companies will be successfully integrated into the Company's business or product offerings, or that such integration will not adversely affect the Company's business, financial condition or results of operations. There can be no assurance that any acquired companies, assets, products or technologies will contribute significantly to the Company's sales or earnings, that the sales and earnings from acquired businesses will not be adversely affected by the integration process or other factors. If the Company is not successful in the integration of such acquired businesses, there could be an adverse impact on the financial results of the Company. There can be no assurance that the Company will continue to be able to identify and consummate suitable acquisition transactions in the future. Possible Volatility of Stock Price. The market price of the Company's Common Stock has been, and may continue to be, extremely volatile. The trading price of the Company's Common Stock could be subject to wide fluctuations in response to quarter-to-quarter variations in operating results, changes in earnings estimates by analysts, announcements of technological innovations or new products by the Company or its competitors, challenges associated with integration of businesses and other events or factors. In addition, the stock market has from time to time experienced extreme price and volume fluctuations which have particularly affected the market price for many high technology companies and which often have been unrelated to the operating performance of these companies. These broad market fluctuations may adversely affect the market price of the Company's Common Stock. 7 USE OF PROCEEDS The Company will not receive any of the proceeds from the sale of the Shares by the Selling Stockholders. SELLING STOCKHOLDERS The following table sets forth certain information regarding ownership of the Common Stock of APC as of February 14, 1997 and the number of Shares that may be offered for the account of the Selling Stockholders or their transferees, distributees, pledgees, donees or other successors in interest from time to time. All of the shares offered hereby were acquired in connection with the APC acquisition of Systems Enhancement. See "Plan of Distribution."

(2) Because the Selling Stockholders or their transferees, distributees, pledges, donees or other successors in interest may sell all or any part of their Shares pursuant to this Prospectus, no estimate can be given as to the number of Shares that will be held by each Selling Stockholder upon termination of this offering. However, prior to the offering each Selling Stockholder held less than one percent (1%) of APC's outstanding shares of Common Stock, based on shares of Common Stock outstanding as of February 14, 1997. 8 PLAN OF DISTRIBUTION The Shares offered hereby may be sold from time to time by the Selling Stockholders acting as principals for their own account. The Company is responsible for the expenses incurred in connection with the registration of the Shares. The Company will receive none of the proceeds from this offering. The Selling Stockholders will pay or assume brokerage commissions or other charges and expenses incurred in the sale of the Shares. In addition, the Company has agreed to indemnify the Selling Stockholders against certain liabilities, including liabilities under the Securities Act, and, in the event that any offering is made by the Selling Stockholders through underwriters, to agree to indemnify such underwriters for such liabilities. The distribution of the Shares by the Selling Stockholders is not currently subject to any underwriting agreement. The Shares covered by this Prospectus may be sold by the Selling Stockholders or their transferees, distributees, pledgees, donees, or other successors in interest from time to time. Such sales may be made at fixed prices that may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices, or at negotiated prices. Such sales may be effected in the over-the-counter market, on the National Association of Securities Dealers Automated Quotation System, on the Nasdaq National Market, or on any exchange on which the Shares may then be listed. The Shares may be sold by one or more of the following: (a) one or more block trades in which a broker or dealer so engaged will attempt to sell all or a portion of the Shares held by the Selling Stockholders as agent but may position and resell a portion of the block as principal to facilitate the transaction; (b) purchases by a broker or dealer as principal and resale by such broker or dealer for its account pursuant to this Prospectus; (c) ordinary brokerage transactions and transactions in which the broker solicits purchasers; (d) in negotiated transactions; and (e) through other means. The Selling Stockholders may effect such transactions by selling Shares to or through broker-dealers, and such broker-dealers will receive compensation in negotiated amounts in the form of discounts, concessions, commissions or fees from the Selling Stockholders and/or the purchasers of the Shares for whom such broker-dealers may act as agent or to whom they sell as principal, or both (which compensation to a particular broker-dealer might be in excess of customary commissions). Such brokers or dealers or the participating brokers or dealers and the Selling Stockholders may be deemed to be "underwriters" within the meaning of the Securities Act, in connection with such sales, and any commissions received by such broker-dealers may be deemed to be underwriting compensation. Any shares covered by the Prospectus that qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than pursuant to this Prospectus. The Selling Stockholders are not restricted as to the price or prices at which they may sell their Shares. Sales of such Shares at less than the market prices may depress the market price of the Company's Common Stock. During the effective time of this Prospectus, the Selling Stockholders have agreed to potential restrictions on resale if notified by the Company of a potential material event that could have a material effect on the Company's business and financial condition, a period commencing upon such notice and ending upon notice by the Company that such potential material event either has been disclosed to the public or no longer constitutes a potential material event. The Selling Stockholders are not restricted as to the number of Shares which may be sold at any one time, and it is possible that a significant number of Shares could be sold at the same time. Boston EquiServe L.P., 150 Royall Street, Canton, Massachusetts 02021, is the transfer agent for the Company's Common Stock. 9 LEGAL MATTERS Certain legal matters with respect to the issuance of the Shares are being passed upon for the Company by Testa, Hurwitz & Thibeault, LLP, Boston, Massachusetts.

Undertakings. The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high and of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in this Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where appropriate, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, II-2 officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. The undersigned registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective. (2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all the requirements for filing on Form S-3 and has duly caused this Amendment No. 1 to Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in West Kingston, Rhode Island on April 22, 1997 .
