MEETINGS OF STOCKHOLDERS OrCAD Special Meeting. The OrCAD Special Meeting is scheduled to be held on Tuesday, December 30, 1997 at 10:00 a.m., local time, at the Crowne Plaza, 14811 Kruse Oaks Blvd., Lake Oswego, Oregon 97035. At the OrCAD Special Meeting, stockholders of OrCAD will consider and vote upon (i) the issuance of OrCAD Common Stock in exchange for all of the issued and outstanding shares of capital stock of MicroSim and all of the outstanding options to acquire shares of MicroSim common stock in connection with the Merger Agreement (the "Issuance"); and (ii) such other business as may be properly brought before the OrCAD Special Meeting. Only holders of record of OrCAD Common Stock at the close of business on November 3, 1997, are entitled to notice of and to vote at the OrCAD Special Meeting. At the close of business on that date, shares of OrCAD Common Stock were outstanding and entitled to vote, of which, shares ( percent ( %)) were held by members of the OrCAD Board, OrCAD's executive officers and their affiliates. The affirmative vote of the holders of a majority of the votes cast on the proposal is required for approval of the Issuance. See "SPECIAL MEETING OF OrCAD STOCKHOLDERS--Record Date; Shares Entitled to Vote; Vote Required." MicroSim Special Meeting. The MicroSim Special Meeting is scheduled to be held on Monday, December 15, 1997, at 10:00 a.m., local time, at MicroSim's offices at 16275 Laguna Canyon Road, Irvine, California 92618. At the MicroSim Special Meeting, shareholders of MicroSim will consider and vote upon (i) a proposal to approve and adopt the Merger Agreement and the Merger; and (ii) such other business as may be properly brought before the MicroSim Special Meeting. Only holders of record of MicroSim common stock, no par value per share ("MicroSim Stock") at the close of business on November 3, 1997, are entitled to notice of and to vote at the MicroSim Special Meeting. At the close of business on that date, shares of MicroSim Stock were outstanding and entitled to vote, of which, shares ( percent ( %)) were held by members of the MicroSim Board, MicroSim's executive officers and their affiliates. The affirmative vote of the holders of shares representing a majority of the number of shares of MicroSim Stock outstanding is necessary to approve and adopt the Merger Agreement and Merger. It is a condition to consummation of the Merger that holders of not more than six percent (6%) of the total number of shares of MicroSim Stock outstanding on the closing date of the Merger (the "Closing Date") exercise dissenters' rights. See "SPECIAL MEETING OF MICROSIM SHAREHOLDERS--Record Date; Shares Entitled to Vote; Vote Required." THE MERGER General. Upon consummation of the Merger, Merger Sub will merge with and into MicroSim, MicroSim will become a wholly owned subsidiary of OrCAD, and the shares of MicroSim Stock then outstanding (other than shares as to which dissenters' rights have been exercised) and the options to acquire shares of MicroSim Stock which are then outstanding will be converted as described below. Effective Time of the Merger. Following receipt of all required approvals and satisfaction or waiver of the other conditions to the Merger, the Merger will be consummated and become effective at the time (the "Effective Time") at which the articles of merger to be filed pursuant to the California Corporations Code (the "Corporations Code") and the articles of merger to be filed pursuant to the Oregon Business Corporation Act (the "Business Corporation Act") are accepted for filing by the Secretary of State of California and the Secretary of State of Oregon, respectively, or such later date and time as may be specified in such articles of merger. See "THE MERGER--Effective Time of the Merger" and "Conditions; Waivers." 2 Conversion of MicroSim Stock and Options to Acquire Shares of MicroSim Stock in the Merger. At the Effective Time, all shares of MicroSim Stock issued and outstanding immediately prior to the Effective Time (other than shares as to which dissenters' rights of appraisal have been duly sought, perfected and are not subsequently withdrawn), and all options to acquire shares of MicroSim Stock outstanding immediately prior to the Effective Time, will be exchanged for OrCAD Common Stock. The 2,697,795 issued and outstanding fully vested shares of MicroSim Stock (including vested shares held under stock purchase agreements) will each be exchanged for .825 shares of OrCAD Common Stock, for an aggregate total of 2,225,680 shares of OrCAD Common Stock (subject to adjustment for fractional shares). The 106,820 shares of unvested MicroSim Stock held under stock purchase agreements will each be valued at .91 shares of fully vested MicroSim Stock, and then the discounted shares exchanged for .825 shares of OrCAD Common Stock, for an aggregate total of 80,195 shares of OrCAD Common Stock (subject to adjustment for fractional shares). The options to acquire 95,640 shares of MicroSim Stock underlying fully vested stock options will be valued by subtracting the exercise price of each option from the "MicroSim Fair Market Value." That value will be determined as .825 times the "OrCAD Fair Market Value." The "OrCAD Fair Market Value" is agreed to be the ten-day closing average of OrCAD's prices on the NASDAQ exchange for the ten consecutive trading days next preceding the third trading day before the Closing Date. The resulting dollar value shall be divided by the OrCAD Fair Market Value, and the underlying fully vested stock option shall then be exchanged for that number of shares of OrCAD Common Stock (subject to adjustment for fractional shares and for variations in the OrCAD Fair Market Value). The options to acquire 228,760 shares of MicroSim Stock underlying unvested stock options will be valued as the fully vested options are valued, except the total value shall be multiplied by .90, to reflect the discounted value of unvested options (subject to adjustment for fractional shares and for variations in the OrCAD Fair Market Value). The foregoing numbers for shares and options may fluctuate based upon option exercises and other events prior to the Effective Time. Fractional Shares. No fractional shares of OrCAD Common Stock will be issued in the Merger. OrCAD will pay to each holder of MicroSim Stock or options to acquire shares of MicroSim Stock an amount in cash (rounded to the nearest whole cent) determined by multiplying (i) the fair market value of a share of OrCAD Common Stock by (ii) the fraction of a share of OrCAD Common Stock which such holder would otherwise be entitled to receive in connection with the Merger. Recommendation of OrCAD Board of Directors. The OrCAD Board has determined the Issuance and the Merger to be fair to and in the best interests of OrCAD and its stockholders and has unanimously approved the Issuance and the Merger Agreement. The OrCAD Board recommends that OrCAD stockholders vote "FOR" the Issuance. The OrCAD Board's recommendations are based upon a number of factors discussed in this Joint Proxy Statement/Prospectus. See "BACKGROUND OF AND REASONS FOR THE MERGER." Opinion of OrCAD Financial Advisor. Redwood Partners LLC ("Redwood Partners") has been retained by OrCAD to act as its financial advisor in connection with the Merger. John C. Savage is a Principal of Redwood Partners and a member of the OrCAD Board. See "CONFLICTS OF INTEREST." Redwood Partners delivered its oral opinion to the OrCAD Board on September 24, 1997 (as confirmed in writing on October 13, 1997, the "Redwood Partners Opinion"), to the effect that, as of such date and based upon the procedures followed, matters considered and assumptions made by Redwood Partners as set forth therein, the consideration to be paid for MicroSim pursuant to the Merger Agreement is fair to OrCAD from a financial point of view. The full text of the Redwood Partners Opinion, which sets forth assumptions made, procedures followed, matters considered, limitations on and scope of the review undertaken, is attached hereto as Appendix B. OrCAD stockholders are urged to read the opinion carefully and in its entirety. The Redwood Partners Opinion is directed only to the fairness to OrCAD of the consideration to be paid for MicroSim pursuant to the Merger Agreement from a financial point of view and should not be deemed to constitute a recommendation by Redwood Partners to OrCAD stockholders to vote in favor of any matter presented in this Joint Proxy Statement/Prospectus. The summary of the Redwood Partners Opinion set forth herein is qualified in its entirety by reference to the full text of such opinion. See "BACKGROUND OF AND REASONS FOR THE MERGER--Opinion of OrCAD Financial Advisor." 3 Recommendation of MicroSim Board of Directors. The MicroSim Board has determined the Merger to be fair to and in the best interests of MicroSim and its shareholders and has unanimously approved the Merger Agreement and the Merger. The MicroSim Board recommends that MicroSim shareholders vote "FOR" the Merger Agreement and the Merger. The MicroSim Board's recommendations are based upon a number of factors discussed in this Joint Proxy Statement/Prospectus. See "BACKGROUND OF AND REASONS FOR THE MERGER" and "CONFLICTS OF INTEREST." Irrevocable Proxy. The principal shareholder of MicroSim, owning an aggregate of 2,165,725 shares of MicroSim Stock and representing approximately 77% of the outstanding shares of MicroSim Stock as of October 16, 1997, has given an irrevocable proxy to OrCAD to vote all of his shares of MicroSim Stock "FOR" approval of the Merger Agreement and the Merger. Exchange of MicroSim Stock and Options to Acquire Shares of MicroSim Stock in the Merger. As soon as practicable after the Effective Time, the Exchange Agent for the Merger (the "Exchange Agent") will deliver to each holder of certificates representing shares of MicroSim Stock (other than dissenting shares) and each holder of options to acquire shares of MicroSim Stock, a form of letter of transmittal and instructions for use in effecting the surrender of such certificates and options for conversion into shares of OrCAD Common Stock. Upon surrender of such certificates and options to the Exchange Agent, together with the letter of transmittal and other required documents, each such holder will receive for each share of MicroSim Stock represented by such certificate or option the number of shares of OrCAD Common Stock into which such shares of MicroSim Stock or options to acquire shares of MicroSim Stock were converted in the Merger, less the number of shares delivered pursuant to the Escrow Agreement. See "THE MERGER--Terms of the Merger" and "Exchange of MicroSim Stock and Options to Acquire Shares of MicroSim Stock." Escrow of OrCAD Common Stock. The Merger Agreement provides that OrCAD will withhold, on a pro-rata basis, ten percent (10%) of the shares of OrCAD Common Stock to be received by holders of MicroSim Stock and options to acquire shares of MicroSim Stock upon consummation of the Merger (the "Escrow Shares"). The Escrow Shares will be delivered to First Trust National Association as escrow agent (the "Escrow Agent"). The Escrow Shares will be held by the Escrow Agent for a period, that, absent unresolved claims, will end on the first anniversary of the Closing Date. Subject to certain limitations set forth in the Merger Agreement, the Escrow Shares will be subject to claims by OrCAD to satisfy MicroSim's obligations under the Merger Agreement to reimburse OrCAD for any and all claims, damages, losses, liabilities, judgments, settlements, costs and expenses incurred by OrCAD by reason of, arising out of, or in connection with any breach or inaccuracy of any representation or warranty of MicroSim contained in the Merger Agreement or the failure of MicroSim to perform any agreement or covenant required to be performed by MicroSim under the Merger Agreement. See "THE MERGER--Escrow of OrCAD Common Stock." Quotation of the OrCAD Common Stock on the Nasdaq National Market. OrCAD has agreed to use all reasonable efforts to cause the OrCAD Common Stock to be issued pursuant to the Merger Agreement to be quoted for trading on the Nasdaq National Market. See "THE MERGER--Quotation of OrCAD Common Stock on Nasdaq National Market." Business of OrCAD Pending the Merger. OrCAD has agreed that, prior to the later of the Closing Date and the Effective Time, except as contemplated by the Merger Agreement, it will operate its business in the usual, regular and ordinary manner. In addition, unless MicroSim agrees in writing or except as otherwise permitted pursuant to the Merger Agreement, prior to the later of the Closing Date and the Effective Time OrCAD will not engage in certain actions specified in the Merger Agreement. See "THE MERGER--Business of OrCAD Pending the Merger." Business of MicroSim Pending the Merger. MicroSim has agreed that, prior to the later of the Closing Date and the Effective Time, except as contemplated by the Merger Agreement, it will operate its business only 4 in the usual, regular and ordinary manner. In addition, unless OrCAD agrees in writing or except as otherwise permitted pursuant to the Merger Agreement, prior to the later of the Closing Date and the Effective Time MicroSim will not engage in certain actions specified in the Merger Agreement. See "THE MERGER-- Business of MicroSim Pending the Merger." No Solicitation. MicroSim has agreed that, prior to the later of the Closing Date and the Effective Time, neither it nor any of its affiliates will, directly or indirectly, initiate, contract with, solicit or encourage any inquiries or proposals by, or enter into any discussions or negotiations with, or disclose any information concerning its business and properties, or afford any access to its properties, books and records to, any third party concerning any merger, consolidation, share exchange or similar transaction involving MicroSim or any purchase of all or a significant portion of the assets of or equity interest in MicroSim, or any other transaction that would involve the transfer or potential transfer of control of MicroSim. If, however, the MicroSim Board receives a written proposal regarding any of the foregoing transactions, and in the opinion of the MicroSim Board (after consultation with legal counsel), the failure to consider such proposal would cause the MicroSim Board to violate its fiduciary duties under the Corporations Code, then the MicroSim Board may consider such proposal. See "THE MERGER--No Solicitation." Management and Operations of MicroSim After the Merger. After the Merger, MicroSim will be a wholly owned subsidiary of OrCAD. MicroSim will operate as one of OrCAD's business units and OrCAD currently intends to maintain MicroSim's corporate headquarters in Irvine, California. After the Merger, MicroSim will have access to resources generally available to OrCAD's other business units, will participate in appropriate activities with other OrCAD business units and will operate under the direction and guidance of OrCAD's senior management and the OrCAD and MicroSim Boards. See "THE MERGER-- Management and Operations of MicroSim After the Merger." Conditions of the Merger; Termination. The consummation of the Merger is conditioned upon the fulfillment or waiver of certain conditions set forth in the Merger Agreement. See "THE MERGER--Conditions; Waivers." The Merger Agreement may be terminated (i) by mutual consent of OrCAD and MicroSim, (ii) by either OrCAD or MicroSim if the Merger has not been consummated by January 31, 1998, and (iii) under certain other circumstances. See "THE MERGER-- Termination; Amendment." Certain Federal Income Tax Consequences. It is expected that the Merger will constitute a reorganization for federal income tax purposes and, accordingly, that no gain or loss will be recognized by holders of MicroSim Stock upon the conversion of MicroSim Stock into OrCAD Common Stock in the Merger. It is further expected that no gain or loss will be recognized by MicroSim or OrCAD as a result of the Merger. See "THE MERGER--Certain Federal Income Tax Consequences." MicroSim shareholders are urged to consult their own tax advisor as to the specific tax consequences to them of the Merger. Regulatory Approvals. The parties to the Merger are not required to file notifications under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and are not aware of any other regulatory approvals required to consummate the Merger other than compliance with the federal securities laws and applicable securities and "blue sky" laws of the various states. Accounting Treatment. It is expected that the Merger will be accounted for as a pooling of interests. See "THE MERGER--Accounting Treatment." Conflicts of Interest. As of the MicroSim Record Date, non-employee directors of the MicroSim Board beneficially owned an aggregate of 125,000 shares of MicroSim Stock and held options to acquire an aggregate of 60,000 shares of MicroSim Stock, exercisable at prices ranging from $3.40 to $3.60 per share. See "STOCK OWNED BY MICROSIM MANAGEMENT AND PRINCIPAL SHAREHOLDERS." Assuming an OrCAD market value of $8.94, the aggregate dollar value of OrCAD Common Stock to be received by these non- 5 employee directors in respect of outstanding shares of MicroSim Stock would be approximately $921,680, representing approximately 4.5% of the aggregate consideration to be received by all holders of MicroSim Stock. Assuming an OrCAD market value of $8.94, the aggregate dollar value of OrCAD Common Stock to be received by these non-employee directors in respect of outstanding options to acquire shares of MicroSim Stock would be approximately $209,611, representing approximately 18.0% of the aggregate consideration to be received by all holders of options to acquire shares of MicroSim Stock. As of the MicroSim Record Date, the executive officers of MicroSim beneficially owned an aggregate of 2,227,725 shares of MicroSim Stock and held options to acquire an aggregate of 105,000 shares of MicroSim Stock, exercisable at prices ranging from $3.40 to $3.60 per share. See "STOCK OWNED BY MICROSIM MANAGEMENT AND PRINCIPAL SHAREHOLDERS." Assuming an OrCAD market value of $8.94, the aggregate dollar value of OrCAD Common Stock to be received by these executive officers in respect of outstanding shares of MicroSim Stock would be approximately $16,421,014, representing approximately 79.7% of the aggregate consideration to be received by all holders of MicroSim Stock. Pursuant to the Merger Agreement, all outstanding options to acquire shares of MicroSim Stock, including those held by the executive officers of MicroSim, will be converted into shares of OrCAD Common Stock. Assuming an OrCAD market value of $8.94, the aggregate dollar value of OrCAD Common Stock to be received by these executive officers in respect of outstanding options to acquire shares of MicroSim Stock would be approximately $392,910, representing approximately 33.8% of the aggregate consideration to be received by all holders of options to acquire shares of MicroSim Stock. At the first OrCAD Board Meeting following consummation of the Merger, Wolfram H. Blume, Chairman of the MicroSim Board, President and Chief Executive Officer of MicroSim, and the largest holder of MicroSim Stock, will become a member of the OrCAD Board. At the Effective Time, he will become the Chief Technical Officer and Senior Vice President of Research and Development of OrCAD. Mr. Blume will also enter into a two (2) year employment agreement with OrCAD. Michael U. Wimbrow, a member of the MicroSim Board, Vice President of Planning and Product Support of MicroSim and the beneficial owner of shares of MicroSim Stock and options to acquire shares of MicroSim Stock, will become Vice President of Product Strategy and Architecture of OrCAD at the Effective Time. Mr. Wimbrow will enter into a one (1) year employment agreement with OrCAD. Additionally, L.A. Delmonico Consulting, Inc. ("Consultant"), an affiliate of Louis A. Delmonico who is a member of the MicroSim Board, is a party to a Consulting Agreement dated August 5, 1996 (the "Consulting Agreement") with MicroSim. Pursuant to the terms of the Consulting Agreement, upon consummation of the Merger Consultant will be entitled to (i) terminate the Consulting Agreement upon no more than 90 days written notice, and (ii) be paid all amounts due under the Consulting Agreement through the termination date plus an additional sum of $144,000 payable in twelve equal monthly installments. Redwood Partners has been retained by OrCAD to act as its financial advisor and to deliver a fairness opinion in connection with the Merger. Pursuant to an engagement letter with OrCAD, Redwood Partners will receive a fee of $200,000 for its opinion and certain services rendered in conjunction with the Merger, of which $50,000 is not contingent upon consummation of the Merger. OrCAD will also reimburse Redwood Partners for its out-of-pocket expenses, including reasonable fees and disbursements of counsel. OrCAD has also agreed to indemnify Redwood Partners and its affiliates, directors, officers, partners, agents and employees, and each person, if any, controlling Redwood Partners or any of its affiliates against certain liabilities, including certain liabilities under the federal securities laws, relating to or arising out of its engagement. John C. Savage, a Principal of Redwood Partners, serves as a member of the OrCAD Board and will continue to so serve after consummation of the Merger. As of October 16, 1997, Mr. Savage owned options to acquire 10,000 shares of OrCAD Common Stock and Principals of Redwood Partners, including Mr. Savage, owned an aggregate of 31,724 shares of OrCAD Common Stock. A predecessor of Redwood Partners was the largest stockholder of OrCAD until September 1996. Dissenters' Rights. Holders of MicroSim Stock have the right to dissent from the proposed Merger and, subject to certain conditions, to receive payment of the "fair value" of their shares of MicroSim Stock, as 6 provided in Sections 1300 through 1312 of the Corporations Code. See "THE MERGER--Rights of Dissenting MicroSim Shareholders." Under the Delaware General Corporation Law (the "General Corporation Law"), OrCAD's stockholders are not entitled to dissenters' rights or appraisal rights with respect to the Merger. RISK FACTORS The stockholders of OrCAD and the shareholders of MicroSim should consider carefully the information set forth herein under the heading "Risk Factors" which discusses, among other things, the risks associated with: the integration of the businesses of OrCAD and MicroSim following the Merger; expenses related to the Merger; the effect of future sales of the shares issued in the Merger on the market for OrCAD Common Stock; termination of relationships with OrCAD by OrCAD's customers or distributors as a result of the Merger; changes in the marketing of MicroSim's products; fluctuation of operating results of OrCAD; competition and changes in technology; dependence on key personnel; certain failures to comply with securities laws in conjunction with previous issuances of MicroSim Stock; protection of intellectual property; and certain anti- takeover protective measures adopted by OrCAD. 7 SELECTED HISTORICAL AND UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL DATA The following selected historical financial data of OrCAD and MicroSim has been derived from their respective historical consolidated financial statements, and should be read in conjunction with such financial statements and the notes thereto, which are included elsewhere in this Joint Proxy Statement/Prospectus.

(2) OrCAD and MicroSim estimate that they will incur direct and indirect costs of approximately $2.5 million in connection with the Merger. This estimate includes fees and charges of financial advisors, attorneys and accountants for both parties, personnel severance costs, the cancellation and continuation of contractual obligations and other integration costs. These nonrecurring costs will be charged to operations in the fiscal quarter in which the Merger is consummated. The pro forma combined book value per share data reflect these estimated transaction costs and their tax effects as if such costs were incurred as of June 30, 1997, but the effects of these costs are not reflected in the pro forma combined net income per share data. (3) The pro forma combined book value per share of OrCAD Common Stock is computed by dividing pro forma stockholders' equity by the pro forma number of common shares and share equivalents outstanding at the end of the period. (4) The MicroSim equivalent pro forma amounts of net income and book value are computed by multiplying the pro forma combined amount per OrCAD share by the exchange ratio of .825 shares of OrCAD Common Stock for each share of MicroSim Stock. 10 COMPARATIVE PER SHARE MARKET INFORMATION ORCAD The OrCAD Common Stock is quoted on the Nasdaq National Market. The table below sets forth for the fiscal periods indicated the high and low sales prices per share of OrCAD Common Stock on the Nasdaq National Market as reported in published financial sources. PRICE PER SHARE OF ORCAD COMMON STOCK ----------------- HIGH LOW -------- -------- Calendar 1996 First Quarter.............................................. $ 13.00 $ 10.75 Second Quarter............................................. 16.25 11.00 Third Quarter.............................................. 15.00 8.38 Fourth Quarter............................................. 11.50 8.38 Calendar 1997 First Quarter.............................................. $ 11.00 $ 6.38 Second Quarter............................................. 11.38 6.13 Third Quarter.............................................. 14.56 10.25 Fourth Quarter (through October 16)........................ 14.75 8.75 On October 13, 1997 the last full trading day prior to announcement of the execution of the Merger Agreement, the reported Nasdaq National Market closing price per share of OrCAD Common Stock was $8.81. On November , 1997 the most recent available date prior to printing this Joint Proxy Statement/Prospectus, the reported Nasdaq National Market closing price per share of OrCAD Common Stock was $ . On that date, there were holders of record. OrCAD stockholders and MicroSim shareholders are urged to obtain current market quotations. OrCAD has never declared or paid cash dividends on shares of OrCAD Common Stock. It is not anticipated that any cash dividends will be paid on OrCAD Common Stock in the foreseeable future. MICROSIM There is no public market for shares of MicroSim Stock. There were holders of record of MicroSim Stock as of November 3, 1997. MicroSim has never declared or paid cash dividends on shares of MicroSim Stock. It is not anticipated that any cash dividends will be paid on MicroSim Stock in the foreseeable future. 11 RISK FACTORS The following factors should be considered carefully by the stockholders of OrCAD, Inc. and the shareholders of MicroSim Corporation in connection with voting on the Issuance and the Merger, respectively. These factors should be considered in conjunction with the other information included elsewhere in this Joint Proxy Statement/Prospectus. RISKS RELATING TO THE MERGER Integration of the Businesses. The management of OrCAD and MicroSim have entered into the Merger Agreement with the expectation that the Merger will result in beneficial synergistic effects for the combined company. See "BACKGROUND OF AND REASONS FOR THE MERGER." Achieving the anticipated benefits of the Merger will depend in part upon whether the integration of the two companies' businesses is achieved in a timely, efficient and effective manner, and there can be no assurance that this will occur. The combination of the two companies will require, among other matters, integration of the companies' respective product offerings and coordination of their research and development efforts. There can be no assurance that such integration and coordination will be accomplished smoothly or successfully. The integration of the two organizations will require the dedication of management resources which will divert those resources from attention to the day-to-day business of the combined company. The difficulties of integration may be increased by the necessity of coordinating geographically separated organizations and integrating personnel with disparate business backgrounds. The process of combining the companies may cause an interruption of, or a loss of momentum in, the activities of either or both of the companies' businesses and may adversely affect the revenue and results of operations of the combined company, at least in the near term. Furthermore, the process of combining the companies could have a material adverse effect on employee morale and on the ability of the combined company to retain the key technical and managerial personnel who are critical to the combined company's future operations. In addition, the announcement and consummation of the Merger could cause customers or potential customers to delay or cancel orders for products as a result of uncertainty over the integration and support of MicroSim's products and product lines by the combined company. Expenses related to the Merger. The negotiation and implementation of the Merger will result in aggregate pre-tax expense to OrCAD estimated at approximately $2.5 million. This estimate includes estimated costs of consummating the Merger, including fees and charges of financial advisors, attorneys and accountants for both parties, personnel severance costs, the cancellation and continuation of contractual obligations and other integration costs. These amounts are preliminary estimates only and are therefore subject to change. These costs will negatively affect OrCAD's results of operations in the quarter in which the Merger is consummated. In addition, there can be no assurance that the combined entity will not incur additional charges in subsequent quarters to reflect costs associated with the Merger. Shares Eligible for Future Sale. If the Issuance and the Merger are approved by the stockholders of OrCAD and the shareholders of MicroSim, respectively, OrCAD will issue to the shareholders and option holders of MicroSim approximately 2,436,354 shares of OrCAD Common Stock (assuming $8.94 as the OrCAD market value). Subject to the next sentence, in general, these shares will be freely tradeable immediately following the Merger. Following publication of financial results covering 30 days of post-Merger combined operations, shares issued in the Merger to persons who may be deemed affiliates of MicroSim could also be publicly sold pursuant to Rule 145 under the Securities Act, subject to certain volume and other resale limitations. Future sales of a substantial number of the foregoing shares could adversely affect or cause substantial fluctuations in the market price of OrCAD Common Stock. See "THE MERGER--Resale of OrCAD Common Stock Issued in the Merger; Affiliates." Customer Termination. The announcement and consummation of the Merger could cause customers and potential customers of OrCAD and MicroSim to seek an alternative vendor for electronic design automation software due to concern about the integration of overlapping product offerings of the two companies. Customer terminations or the failure to attract new customers could have a material adverse effect on the business, financial condition and results of operations of the combined company. 12 Distributor Termination. OrCAD intends to transfer most of the responsibility for selling MicroSim's products to OrCAD's telesales and direct sales organizations in North America. As a result of this transition, MicroSim's North American distributors could return unsold software products, which could have a material adverse effect on the business, financial condition and results of operations of the combined company. With regard to international distribution, the two companies use the same independent distributors in certain countries and competing distributors in other countries. OrCAD may make changes to its international distribution following the consummation of the Merger. As a result of this transition, sales of MicroSim's and OrCAD's products could decrease and distributors could return unsold software products, both of which events could have a material adverse effect on the business, financial condition and results of operations of the combined company. Marketing Risks. OrCAD intends to transfer all responsibility for marketing MicroSim's products to OrCAD's marketing department. This will result in different product positioning and different marketing campaigns which may cause some current and potential customers to choose another provider of products which are similar to MicroSim's. In addition, OrCAD may change the publications in which MicroSim products are advertised, as well as the manner in which MicroSim's products are advertised and promoted. These changes could have a material adverse effect on the business, financial condition and results of operations of the combined company. Changes in Customer Support Model. OrCAD may choose to change the model by which MicroSim products have been supported under previous product support agreements. These product support agreements provided lifetime telephone technical support at no additional cost to the customer. If OrCAD makes any changes to this model, such changes could have a material adverse effect on the business, financial condition and results of operations of the combined company. Product Overlap or Discontinuance Revenue Risks. MicroSim offers certain products that overlap with OrCAD's current product offerings. The overlap may cause sales of some existing products of OrCAD or MicroSim to be discontinued, and will cause violation of exclusivity commitments made to two software vendors for whom OrCAD acts as a reseller. No assurance can be given that OrCAD will successfully negotiate a resolution of these violations, or that, if OrCAD is unsuccessful in such negotiations, resulting damages will not have a material adverse effect upon the combined company's financial condition and results of operations. MicroSim also offers products that, due to OrCAD's business model, may be discontinued. Changes to product offerings, or perceived changes, and their effects on customers could have a material adverse effect on the business, financial condition and results of operations of the combined company. Fluctuation of Operating Results. A variety of factors may cause period-to- period fluctuations in the operating results of the combined company following the Merger. Such factors include, but are not limited to, the integration of the businesses as noted above, competitive pricing pressures, revenue and expenses related to new products or revisions to existing products, changes in distribution channels or product mix, and timing of closing of significant sales. Singularly or in combination, these factors could adversely affect the combined company's operating results and financial condition. Dependence on Key Personnel. The success of the combined company will depend in significant part upon the continued service of its key technical, professional and senior management personnel. Currently, none of OrCAD's key technical, professional or senior management personnel are bound by employment agreements, but OrCAD will enter into an employment agreement with each of Wolfram H. Blume and Michael U. Wimbrow in connection with the Merger. The future success of the combined company will also depend on its continuing ability to attract and retain highly qualified technical, professional and managerial personnel. Competition for such personnel is intense, and there can be no assurance that the combined company can retain its key technical, professional and managerial employees or that it can attract, assimilate or retain other highly qualified personnel in the future. Failure to attract and retain key technical, professional and managerial personnel could have a material adverse effect on the combined company's operating results. See "BUSINESS OF OrCAD--Employees." Conflicts of Interest. Certain directors and executive officers of OrCAD and MicroSim have interests in connection with the Merger that are in addition to those of the stockholders of OrCAD and the shareholders of MicroSim generally. See "CONFLICTS OF INTEREST" and "BACKGROUND OF AND REASONS FOR THE MERGER-- Opinion of OrCAD Financial Advisor." 13 Certain Failures to Comply with Securities Laws in Conjunction with Previous Issuances by MicroSim. MicroSim has offered and sold shares of its common stock, options or other securities to its employees pursuant to its Employee Stock Purchase Program, Employee Profit Sharing Program and Stock Option Plan and has issued a total of 813,000 shares of its common stock to employees, other than directors or officers of MicroSim, pursuant to such programs and plan. The offers and sales pursuant to such programs and plan were not registered or qualified under federal or state securities laws and an exemption from registration or qualification was not available with respect to some issuances of such stock. If an exemption was not available and the offers and sales were made in violation of federal securities laws, the Commission may enter an order requiring MicroSim to cease and desist from committing a future violation of the Securities Act or any rules and regulations promulgated thereunder and requiring MicroSim to comply, or take steps to effect compliance, with the Securities Act and any rules and regulations promulgated thereunder upon such terms and conditions and within such time as the Commission may specify. Such order of the Commission may also require future compliance or steps to effect future compliance, either permanently or for such period of time as the Commission may specify, with respect to the Securities Act or any rule or regulation promulgated thereunder with respect to any security, any issuer or any other person. In addition, if an exemption from registration or qualification was not available and offers and sales were made in violation of federal securities laws, the persons purchasing the securities from MicroSim may sue to recover the consideration paid for such securities and the interest thereon, less the amount of any income received thereon, upon any tender of such securities, or for damages if such persons no longer own the securities. Similar remedies exist under state law as well. RISKS RELATING TO BOTH ORCAD AND MICROSIM Competition and Changes in Technology. The EDA industry is characterized by rapidly evolving technology and strong competition. OrCAD currently competes in the desktop EDA market most directly with Viewlogic, which offers Windows and UNIX-based products. MicroSim competes with small, privately held companies, including Intusoft and Deutsch Technology Research. Each of OrCAD and MicroSim also faces competition from larger vendors of traditional UNIX- based EDA products. Some of these companies, such as Cadence, Synopsis, Viewlogic, Mentor Graphics and others, have either announced or shipped Windows-based products. OrCAD also competes with smaller, privately held companies. A number of OrCAD's and MicroSim's competitors have significantly greater financial, technical and marketing resources than OrCAD or MicroSim, and strong name recognition. There can be no assurance that these competitors will not use their superior resources and visibility, and installed customer bases, to successfully develop better products and/or market their products more effectively than those of OrCAD or MicroSim. In particular, as a result of the wide acceptance of UNIX-based EDA tools, vendors of such tools have established long-term relationships with many of OrCAD's and MicroSim's current and potential customers, and may have the ability to offer these customers a broad suite of Windows- and UNIX-based products to satisfy the entire range of their design needs. Finally, in addition to competition from EDA software vendors, OrCAD and MicroSim face competition from the internal design groups of many of their customers, who design and develop customized electronic design automation tools for their own particular needs and therefore may be reluctant to purchase products offered by OrCAD, MicroSim or other independent EDA vendors. There can be no assurance that OrCAD or MicroSim will be able to convert such internal design groups into users of their products. More generally, there can be no assurance that OrCAD or MicroSim will be able to compete successfully against current and future competitors, both direct and indirect, or that competitive pressures faced by OrCAD or MicroSim will not materially adversely affect their business, financial condition and results of operations. See "BUSINESS OF OrCAD-- Competition," and "BUSINESS OF MICROSIM--Competition." Protection of Intellectual Property. Each of OrCAD's and MicroSim's success is heavily dependent upon its proprietary software technology. OrCAD and MicroSim currently rely upon a combination of trade secret, copyright and trademark laws, and contractual provisions to protect their proprietary rights in their software products. OrCAD ships its software with a security device to all customers outside the U.S. and Canada. MicroSim ships its software with a security device to all customers. Both OrCAD and MicroSim generally enter into proprietary information and confidentiality agreements with their employees and distributors, and limit 14 access to and distribution of their software, documentation and other proprietary information. OrCAD does not license or release the source code for its proprietary software to its customers, except in connection with OEM development agreements. MicroSim does not license or release the source code for its proprietary software to its customers. Despite these precautions, there can be no assurance that a third party will not copy or otherwise obtain and use OrCAD's or MicroSim's products or technology without authorization, or develop similar or superior technology independently. In particular, both OrCAD and MicroSim distribute their products pursuant to "shrink-wrap" licenses. There can be no assurance that such licenses are enforceable. In addition, effective copyright and trade secret protection may be unavailable or limited in certain foreign countries. Although each of OrCAD and MicroSim believes that its products do not infringe on the proprietary rights of third parties, and although neither OrCAD nor MicroSim have received any communications from third parties alleging the infringement of the proprietary rights of such parties, there can be no assurance that infringement claims will not be asserted against OrCAD or MicroSim in the future and that any such claims will not require OrCAD or MicroSim to enter into costly litigation. Irrespective of the validity or the successful assertion of such claims, any such litigation could result in significant diversions of effort by OrCAD's or MicroSim's respective technical and management personnel, as well as OrCAD's or MicroSim's incurrence of significant costs with respect to the defense thereof, and could have a material adverse effect on their business, financial condition and results of operations. In addition, if any claims or actions are asserted against OrCAD or MicroSim, they may choose to or be required to obtain a license under a third party's intellectual property rights. There can be no assurance that under such circumstances a license would be available upon reasonable terms or at all. See "BUSINESS OF OrCAD--Proprietary Rights," "BUSINESS OF MICROSIM-- Proprietary Rights." Anti-Takeover Provisions. Certain provisions of OrCAD's Restated Certificate of Incorporation and Restated Bylaws and the General Corporation Law may have the effect of making it more difficult for a third party to acquire control of OrCAD through either a tender offer or a proxy contest for the election of directors. This could limit the price that certain investors might be willing to pay in the future for shares of OrCAD Common Stock and could make the removal of incumbent directors more difficult. See "DESCRIPTION OF OrCAD CAPITAL STOCK." Volatility of Stock Price. The prices for OrCAD Common Stock have fluctuated widely in the past. The management of OrCAD believes that such fluctuations may have been caused by quarterly variations in operating results, announcements of technological innovations, the introduction of new products or pricing changes by OrCAD or its competitors, changes in earnings estimates by analysts and other events or factors, including changes in the EDA industry in general. In addition, the stock market has from time to time experienced extreme price and volume fluctuations that have particularly affected the market prices of securities of high technology companies, which fluctuations have often been unrelated to the operating performance of particular companies. OrCAD anticipates that prices for OrCAD Common Stock may continue to be volatile following the Merger. The trading price of OrCAD Common Stock at the Effective Time may vary from the prices as of the date hereof, or the date on which the stockholders of OrCAD vote on the Issuance and the shareholders of MicroSim vote on the Merger, as a result of changes in the business, operating results, financial condition and prospects of OrCAD, market assessments of the likelihood that the Merger will be consummated and the timing thereof, general market and economic conditions and other factors. 15 SPECIAL MEETING OF ORCAD STOCKHOLDERS GENERAL This Joint Proxy Statement/Prospectus is being furnished to the stockholders of OrCAD, as part of the solicitation of proxies by the OrCAD Board from holders of the outstanding shares of OrCAD Common Stock, for use at the OrCAD Special Meeting to be held on Tuesday, December 30, 1997, at the Crowne Plaza, 14811 Kruse Oaks Blvd., Lake Oswego, Oregon 97035, commencing at 10:00 a.m., local time, and at any adjournments or postponements thereof. This Joint Proxy Statement/Prospectus, together with the enclosed proxy card, is first being mailed to stockholders of OrCAD and shareholders of MicroSim on or about November , 1997. MATTERS TO BE CONSIDERED AT THE MEETING At the OrCAD Special Meeting, stockholders of record of OrCAD as of the close of business on November 3, 1997, will consider and vote upon (i) the Issuance, and (ii) such other business as may properly be brought before the OrCAD Special Meeting. Holders of OrCAD Common Stock will not be entitled to dissenters' rights as a result of the Issuance. See "THE MERGER--Terms of the Merger." THE ORCAD BOARD HAS UNANIMOUSLY APPROVED THE ISSUANCE AND THE MERGER AGREEMENT AND RECOMMENDS THAT ORCAD STOCKHOLDERS VOTE "FOR" APPROVAL OF THE ISSUANCE. SEE "BACKGROUND OF AND REASONS FOR THE MERGER." As of the date of this Joint Proxy Statement/Prospectus, the OrCAD Board does not know of any other matters to be presented for action by the stockholders at the OrCAD Special Meeting. OrCAD's Restated Bylaws require that notice of stockholder proposals and nominations for director be delivered to the Secretary of OrCAD not less than 60 days nor more than 90 days prior to the date of an annual meeting, unless notice or public disclosure of the date of the meeting occurs less than 60 days prior to the date of such meeting, in which event, stockholders may deliver such notice not later than the 10th day following the day on which notice of the date of the meeting was mailed or public disclosure thereof was made. If any other matters are properly brought before the OrCAD Special Meeting, the persons named in the proxy will vote the shares represented by such proxy upon such matters as determined by a majority of the OrCAD Board. RECORD DATE; SHARES ENTITLED TO VOTE; VOTE REQUIRED The OrCAD Board of Directors has fixed the close of business on November 3, 1997 (the "OrCAD Record Date") as the record date for the determination of the holders of OrCAD Common Stock entitled to notice of and to vote at the OrCAD Special Meeting. Accordingly, only holders of record of OrCAD Common Stock at the close of business on the OrCAD Record Date will be entitled to vote at the OrCAD Special Meeting, with each such share entitling its owner to one vote on all matters properly presented at the OrCAD Special Meeting. On the OrCAD Record Date, there were approximately beneficial holders of the shares of OrCAD Common Stock then outstanding. The presence, in person or by proxy, of a majority of the total number of outstanding shares of OrCAD Common Stock entitled to vote at the OrCAD Special Meeting is necessary to constitute a quorum for the transaction of business at the OrCAD Special Meeting. Under Section 6(i) of Part III of Schedule D to the Bylaws of the National Association of Securities Dealers, Inc. (the "NASD"), the affirmative vote of a majority of the total votes cast on the proposal is required for approval of the Issuance. Abstention from voting and broker nonvotes will have the practical effect of voting against the Issuance since they represent one less vote for such approval. PROXIES; PROXY SOLICITATION Shares of OrCAD Common Stock represented by properly executed proxies received at or prior to the OrCAD Special Meeting that have not been revoked will be voted at the OrCAD Special Meeting in accordance 16 with the instructions contained therein. Shares of OrCAD Common Stock represented by properly executed proxies for which no instruction is given will be voted "FOR" approval of the Issuance. OrCAD stockholders are requested to complete, sign, date and return promptly the enclosed proxy card in the postage-prepaid envelope provided for this purpose to ensure that their shares are voted. A stockholder may revoke a proxy at any time prior to its exercise by filing written notice of revocation with, or by delivering a duly executed proxy bearing a later date to, Corporate Secretary, OrCAD, Inc., 9300 S.W. Nimbus Avenue, Beaverton, Oregon 97008 or by attending the OrCAD Special Meeting and voting in person. Mere attendance at the OrCAD Special Meeting will not in and of itself revoke a proxy. If the OrCAD Special Meeting is postponed or adjourned for any reason, at any subsequent reconvening of the OrCAD Special Meeting all proxies will be voted in the same manner as such proxies would have been voted at the original convening of the OrCAD Special Meeting (except for any proxies that have theretofore effectively been revoked or withdrawn), notwithstanding that they may have been effectively voted on the same or any other matter at a previous meeting. Proxy Solicitation. OrCAD will bear the cost of soliciting proxies from its stockholders. In addition to use of the mails, proxies may be solicited personally or by telephone by directors, officers and employees of OrCAD, who will not be specially compensated for such activities. Such solicitations may be made personally, or by mail, facsimile, telephone, telegraph or messenger. OrCAD will also request persons, firms and companies holding shares in their names or in the name of their nominees, which are beneficially owned by others, to send proxy materials to and obtain proxies from such beneficial owners. OrCAD will reimburse such persons for their reasonable expenses incurred in that connection. 17 SPECIAL MEETING OF MICROSIM SHAREHOLDERS GENERAL This Joint Proxy Statement/Prospectus is being furnished to holders of MicroSim Common Stock, in connection with the solicitation of proxies by the MicroSim Board of Directors for use at the Special Meeting of MicroSim shareholders to be held on Monday, December 15, 1997, at MicroSim's offices at 16275 Laguna Canyon Road, Irvine, California, 92618, commencing at 10:00 a.m., local time, and at any adjournments or postponements thereof. This Joint Proxy Statement/Prospectus and the accompanying form of proxy is first being mailed to shareholders of MicroSim on or about November , 1997. MATTERS TO BE CONSIDERED AT THE MEETING At the MicroSim Special Meeting, shareholders of record of MicroSim as of the close of business on November 3, 1997 will consider and vote upon a proposal to approve and adopt the Merger Agreement and the Merger. The Merger Agreement provides that, upon the terms and subject to the conditions thereof, Merger Sub will merge with and into MicroSim, MicroSim will become a wholly owned subsidiary of OrCAD, and all shares of MicroSim Stock issued and outstanding immediately prior to the Effective Time (other than shares as to which dissenters' rights of appraisal have been duly sought, perfected and are not subsequently withdrawn), and all options to acquire shares of MicroSim Stock outstanding immediately prior to the Effective Time, will be exchanged for OrCAD Common Stock. The 2,697,795 issued and outstanding fully vested shares of MicroSim Stock (including vested shares held under stock purchase agreements) will each be exchanged for .825 shares of OrCAD Common Stock, for an aggregate total of 2,225,680 shares of OrCAD Common stock (subject to adjustment for fractional shares). The 106,820 shares of unvested MicroSim Stock held under stock purchase agreements will each be valued at .91 shares of fully vested MicroSim Stock, and then the discounted shares exchanged for .825 shares of OrCAD Common Stock, for an aggregate total of 80,195 shares of OrCAD Common Stock (subject to adjustment for fractional shares). The options to acquire 95,640 shares of MicroSim Stock underlying fully vested stock options will be valued by subtracting the exercise price of each option from the "MicroSim Fair Market Value." That value will be determined as .825 times the "OrCAD Fair Market Value." The resulting dollar value shall be divided by the OrCAD Fair Market Value, and the underlying fully vested stock option shall then be exchanged for that number of shares of OrCAD Common Stock (subject to adjustment for fractional shares and for variations in the OrCAD Fair Market Value). The options to acquire 228,760 shares of MicroSim Stock underlying unvested stock options will be valued as the fully vested options are valued, except the total value shall be multiplied by .90, to reflect the discounted value of unvested options (subject to adjustment for fractional shares and for variations in the OrCAD Fair Market Value). The foregoing numbers for shares and options may fluctuate based upon option exercises and other events prior to the Effective Time. See "THE MERGER--Terms of the Merger." No fractional shares of OrCAD Common Stock will be issued in the Merger. The fair market value of any fractional share resulting from the Merger will be paid in cash. See "THE MERGER--Terms of the Merger--Fractional Shares." Holders of MicroSim Stock will be entitled to dissenters' rights as a result of the Merger. See "THE MERGER--Rights of Dissenting MicroSim Shareholders." THE MICROSIM BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE MERGER AND RECOMMENDS THAT MICROSIM SHAREHOLDERS VOTE "FOR" APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND THE MERGER. SEE "BACKGROUND OF AND REASONS FOR THE MERGER" AND "CONFLICTS OF INTEREST." RECORD DATE; SHARES ENTITLED TO VOTE; VOTE REQUIRED The close of business on November 3, 1997 (the "MicroSim Record Date") has been fixed as the record date for determining the holders of MicroSim Stock, who are entitled to notice of and to vote at the MicroSim Special Meeting. As of the MicroSim Record Date, there were shares of MicroSim Stock outstanding and entitled to vote. The presence, in person or by proxy, of the holders of shares representing a majority of the 18 voting power of the MicroSim Stock entitled to vote, is necessary to constitute a quorum for the transaction of business at the MicroSim Special Meeting. The affirmative vote of holders of shares representing a majority of the number of shares of MicroSim Stock outstanding is necessary to approve and adopt the Merger Agreement and the Merger. Abstentions from voting will have the practical effect of voting against the approval and adoption of the Merger Agreement and the Merger since they represent one less vote for adoption of such proposals. It is a condition of the Merger that holders of not more than six percent (6%) of the total number of shares of MicroSim Stock outstanding exercise dissenter's rights. See "THE MERGER--Conditions; Waivers." The principal shareholder of MicroSim, owning an aggregate of 2,165,725 shares of MicroSim Stock and representing approximately 77% of the outstanding shares of MicroSim Stock as of October 16, 1997, has given an irrevocable proxy to OrCAD to vote all of his shares of MicroSim Stock for approval of the Merger Agreement and the Merger. Accordingly, approval of the Merger Agreement and the Merger at the MicroSim Special Meeting is assured. PROXIES; PROXY SOLICITATION Shares of MicroSim Stock represented by properly executed proxies received at or prior to the MicroSim Special Meeting that have not been revoked will be voted at the Special Meeting in accordance with the instructions contained therein. Shares of MicroSim Stock represented by properly executed proxies for which no instruction is given will be voted "FOR" approval and adoption of the Merger Agreement and the Merger. MicroSim shareholders are requested to complete, sign, date and return promptly the enclosed proxy card in the postage-prepaid envelope provided for this purpose to ensure that their shares are voted. A shareholder may revoke a proxy by submitting at any time prior to the vote on the Merger Agreement and the Merger a written notice of revocation to the Secretary of MicroSim or by attending the MicroSim Special Meeting and voting in person. Mere attendance at the MicroSim Special Meeting will not in and of itself revoke a proxy. If the MicroSim Special Meeting is postponed or adjourned for any reason, at any subsequent reconvening of the MicroSim Special Meeting all proxies will be voted in the same manner as such proxies would have been voted at the original convening of the MicroSim Special Meeting (except for any proxies that have theretofore effectively been revoked or withdrawn), notwithstanding that they may have been effectively voted on the same or any other matter at a previous meeting. MicroSim will bear the cost of soliciting proxies from its shareholders. In addition to solicitation by mail, directors, officers and employees of MicroSim may solicit proxies by telephone, telegram or otherwise. Such directors, officers and employees of MicroSim will not be additionally compensated for such solicitation, but may be reimbursed for out-of-pocket expenses incurred in connection therewith. 19 BACKGROUND OF AND REASONS FOR THE MERGER BACKGROUND The acquisition of complementary businesses has been an important component of OrCAD's business strategy. OrCAD continually evaluates potential acquisition or merger opportunities and possible alliances, technology purchases and strategic transactions with other companies in the EDA industry. Combinations offering access to new markets or complementary product lines are of strategic importance to OrCAD. In June 1995, OrCAD acquired Massteck, Ltd., a developer of Windows-based PCB layout technology. This acquisition enabled OrCAD to introduce the OrCAD Layout for Windows product family in June 1995, simultaneously with the release of OrCAD Capture for Windows. In December 1995, OrCAD acquired Intelligent Systems Japan, OrCAD's distributor in Japan since 1991, and as a result operates OrCAD Japan, K.K. as a wholly owned subsidiary. In April 1997, OrCAD acquired component information systems technology and sales and development personnel from TEAM Corporation. In June 1997, OrCAD acquired component information systems technology and development personnel from Q Point Technology. OrCAD has had business relationships with MicroSim since 1986. From 1992 through early 1994, pursuant to the terms of a reseller agreement OrCAD marketed and sold PC-based analog and mixed-signal simulation products developed by MicroSim. These products were complementary to OrCAD's digital design products. In 1994, members of the OrCAD Board and the MicroSim Board held preliminary discussions concerning a possible merger of the companies. These discussions were terminated before a definitive agreement was reached. Shortly thereafter, the reseller arrangement was discontinued by mutual agreement. Since March 1997, OrCAD has offered alternative analog and mixed-signal simulation software products under the terms of a reseller agreement with Deutsch Technology Research ("DTR"). OrCAD has marketed and sold various versions of DTR's "DR. SPICE" and "Dr. SPICE 2000 A/D" software products since that time. However, market acceptance of these product offerings has been modest. Since December 1995, OrCAD Japan has offered alternative analog and mixed-signal simulation software products under the terms of a reseller agreement with Intusoft. In June 1997, while attending The Design Automation Conference in Anaheim, California, Mr. Michael F. Bosworth, Chairman of the Board, President and Chief Executive Officer of OrCAD, met with Mr. Wolfram H. Blume, Chairman of the Board, President and Chief Executive Officer of MicroSim. Preliminary discussions were held regarding the possibility of a merger of the two companies. On June 10, 1997, OrCAD and MicroSim executed and delivered a Mutual Confidentiality Agreement and OrCAD retained Redwood Partners to act as its financial advisor for the transaction. Shortly thereafter, Mr. Bosworth engaged in discussions with certain key MicroSim management personnel to learn more about MicroSim's business and the changes that had occurred in various aspects of its business during the three years since OrCAD's initial discussions with MicroSim. Mr. Blume and his staff provided Mr. Bosworth with certain operational and financial information to further explore a potential combination. On July 28, 1997, in a meeting held in Mr. John C. Savage's offices, the principals of both companies reached a conceptual working framework outlining the basic terms and conditions under which a prospective merger of the companies could be pursued. On July 30, 1997, as a part of a regularly scheduled meeting of the MicroSim Board, Mr. Blume presented alternative strategies, the risks and benefits of continued operations as an independent company, and the strategic alternatives of a business combination, including a combination with OrCAD. The MicroSim Board authorized Mr. Blume to continue due diligence and negotiations regarding a merger with OrCAD. On August 5, 1997, as a part of a regularly scheduled meeting of the OrCAD Board, Mr. Bosworth made a presentation to the OrCAD Board concerning the strategic and market potential of a 20 combination with MicroSim. Based on the information provided by MicroSim, a review by OrCAD senior management of the strategic considerations of a combination, and other information, the OrCAD Board authorized Mr. Bosworth to continue due diligence and negotiations regarding a merger with MicroSim. On August 11, 1997 and August 12, 1997, certain representatives of OrCAD's finance department traveled to Irvine, California and met off-site with Mr. Bruce A. Warren, MicroSim's Chief Financial Officer; meetings were also held with representatives of Ernst & Young LLP, MicroSim's independent auditors. MicroSim provided OrCAD with financial, employment and general operational information. Subsequently, other members of OrCAD's management team met with their MicroSim counter-parts to perform due diligence work in their respective areas of responsibility. On August 14, 1997 and August 15, 1997, Mr. Blume and Mr. Michael U. Wimbrow, Vice President of Planning and Product Support of MicroSim, visited OrCAD's offices in Beaverton, Oregon for a presentation by Mr. Bosworth of an overview of OrCAD, its products and strategic direction. The parties discussed and identified the potential for operational synergies in the combined company and identified items requiring clarification and further due diligence. On August 21, 1997 and August 22, 1997, Mr. Warren visited OrCAD and its independent auditors KPMG Peat Marwick LLP to conduct an operational and financial review of OrCAD. Subsequently, other members of MicroSim's management team met with their OrCAD counter-parts to perform due diligence work in their respective areas of responsibility. Between July 28, 1997 and October 10, 1997, several meetings and telephone calls between Mr. Bosworth and Mr. Blume and their respective advisors resulted in agreement on the terms of a tax-free reorganization as described elsewhere in this Joint Proxy Statement/Prospectus. A definitive Agreement and Plan of Merger to merge the two companies was drafted by OrCAD and presented to MicroSim on August 18, 1997 for review. On September 24, 1997 the OrCAD Board met with senior executives of OrCAD and OrCAD's outside legal advisors to consider approval of the Merger Agreement. OrCAD's financial advisor, Redwood Partners, presented its financial analysis of the terms and conditions of the Merger, and at the conclusion of its presentation, Redwood Partners delivered to the OrCAD Board its opinion as to the fairness, from a financial point of view, to OrCAD's stockholders of the consideration to be paid pursuant to the Merger. See "Opinion of OrCAD Financial Advisor". Final board of directors approval was obtained from the OrCAD Board on October 10, 1997 and from the MicroSim Board on October 13, 1997. On October 13, 1997, OrCAD and MicroSim signed the Merger Agreement, and issued press releases providing the essential details of the Merger Agreement. JOINT REASONS FOR THE MERGER OrCAD and MicroSim have identified several mutual benefits of the Merger that they believe will contribute to the success of both companies, including: Complementary Products and Distribution. The primary revenue producing products of the two companies complement each other with little duplication or overlap. The Merger, if properly implemented, has the potential to position the combined company as a leader in the emerging mainstream Windows NT enterprise EDA market for system-level design. In North America, OrCAD has built a strong presence in the marketplace with a telesales organization; similarly, MicroSim has built a strong presence in the marketplace with a telesales organization and several value added resellers. The OrCAD sales organization was recently complemented by a direct sales force as a result of OrCAD's acquisition of Team Corporation in April 1997. With the additional product breadth from MicroSim, OrCAD believes that the telesales and field sales organizations of the combined company have the potential to be more efficient and effective than the current separate organizations. 21 Internationally, OrCAD and MicroSim share distributors in several countries and believe the Merger has the potential to provide the critical mass and increased market presence necessary to accelerate the combined company's market development in those countries. The Merger is expected to leverage OrCAD's value added reseller partner network by the addition of some MicroSim distributors. OrCAD's Japan distribution will be augmented through the Merger with the addition of MicroSim personnel who are currently working in Japan. After the Merger, MicroSim's wholly owned Japanese subsidiary will merge into OrCAD Japan, K.K. Existing distributor relationships will be evaluated on a "case by case" basis. Initially, OrCAD does not expect to significantly change product offerings and support in North America. Later, as the combined company prioritizes its development plans, certain products may be withdrawn from sale and further development. The installed customer base will be protected by continued support for a reasonable period of time, and as appropriate, attractive upgrade terms and paths to alternative OrCAD products will be offered where pre-Merger products of either company are discontinued. Complementary Technologies. MicroSim's core technology and expertise is in analog and mixed-signal simulation technology. OrCAD's core technology lies in integrated digital design automation. While each company's core expertise is complementary to the other, there is some technology overlap and duplication of expertise between the two companies. This is expected to facilitate joint development project staffing and allow better coverage in key design and functional specialties. ORCAD'S REASONS FOR THE MERGER In addition to the mutual reasons for the Merger stated above, the OrCAD Board believes the following strategic factors will also contribute to the success of the combined company: Core Technology. OrCAD's strategic intent is to own the core technologies embodied in its products. OrCAD believes technology ownership is essential in order to provide customers innovative and cost-effective products in today's highly competitive EDA industry. Full Line EDA Supplier. Both OrCAD and MicroSim have developed world leadership positions in their respective sectors of the desktop EDA market. However, both companies envision their strategic opportunity to be leadership of the emerging market for enterprise standardization on Windows NT-based EDA solutions for system-level design. The resulting solution breadth of this combination strengthens the combined company's ability to serve the needs of the enterprise customer. As this part of the EDA market matures, vendors with the most complete solutions and broadest product offerings are expected to be better positioned to succeed. Functional Area Leadership. The functional areas for system-level EDA tools include the following: 1. Schematic Capture and Hardware Description Language (HDL) design entry; 2. PCB Layout; 3. Digital Simulation; 4. Analog/Mixed-Signal Simulation; and 5. Component Information Systems. OrCAD's strategy is to be the industry leader and de facto EDA standard for Windows NT-based EDA tools in each of these mainstream design areas. The combined company's strategy will be to improve its market position by utilizing its combined engineering capabilities to focus more intently on specific design and development objectives. Growth and Vertical Integration. MicroSim has established itself as a leading supplier of analog and mixed-signal simulation technology for the desktop EDA market. OrCAD's strategy is to expand the analog and mixed-signal simulation business and to develop or acquire other EDA technologies for those markets. By acquiring the leading supplier of Windows NT-based analog tools, OrCAD will obtain resources that can assist it to reach new markets and maintain a leadership position in an increasingly competitive desktop EDA market. 22 In the course of its deliberations in arriving at its unanimous decision to approve the Merger, the OrCAD Board reviewed and considered with OrCAD's management a number of other factors relevant to the Merger. The factors the OrCAD Board considered included, but were not limited to, (a) information concerning OrCAD's and MicroSim's respective businesses, historical financial performance, operations, products and technologies; (b) OrCAD's and MicroSim's strategic direction and future product offerings and opportunities; (c) an analysis of OrCAD's and MicroSim's respective future contributions to revenue, operating profits and net profits of the combined company; (d) compatibility of the management and corporate cultures of OrCAD and MicroSim; (e) premiums to market and multiples paid in other comparable merger and acquisition transactions; (f) the structure and content of the proposed Merger Agreement, including the ability to account for the transaction as a pooling of interests; (g) a financial presentation by Redwood Partners, including the opinion of Redwood Partners that the consideration to be paid for MicroSim pursuant to the Merger Agreement was fair from a financial point of view to OrCAD's stockholders; and (h) reports from management, and financial and legal advisors as to the results of their due diligence investigation of MicroSim. For a discussion of many of the foregoing matters, see "Opinion of OrCAD Financial Advisor" below. MICROSIM'S REASONS FOR THE MERGER In addition to the mutual reasons for the Merger stated above, the MicroSim Board believes the following strategic factors support the merger: Consolidation in the EDA industry. The EDA industry has been undergoing a period of consolidation. MicroSim believes that larger companies with significant brand-name recognition will be better able to compete in this market. As a result of the Merger, MicroSim expects to strengthen its ability to bring a competitive level of resources to bear, compared to other companies. Expanded Market Reach. OrCAD has the largest customer base in the EDA industry, with over 200,000 products sold under the OrCAD name since 1986. MicroSim believes that access to OrCAD's large customer base significantly increases the revenue opportunity compared to MicroSim's current customer base. Ownership in the Combined Company. The Merger will enable MicroSim shareholders and option holders to convert all of their shares, and options to acquire shares, of MicroSim Stock into publicly tradable shares of OrCAD Common Stock. In reaching its unanimous decision to enter into and approve the Merger Agreement, the MicroSim Board reviewed and considered a number of relevant factors. The factors the MicroSim Board considered included, but were not limited to, (a) information concerning OrCAD's and MicroSim's respective businesses, historical financial performance, operations, products and technologies; (b) current financial market conditions and historical market prices, volatility and trading information with respect to OrCAD Common Stock; (c) the consideration to be received by MicroSim shareholders and option holders in the Merger and its relation to MicroSim's expected contribution to the earnings of the combined company; (d) the terms and conditions of the Merger, including the parties' representations, warranties and obligations thereunder and the fact that the Merger will enable its shareholders to exchange their shares on a tax-free basis; (e) the effects of the Merger on MicroSim's customers and business; (f) the prospects of MicroSim as an independent company; and (g) the reports of management, legal and other financial advisors regarding their due diligence investigations of OrCAD. RECOMMENDATION OF ORCAD BOARD The OrCAD Board has determined the Issuance and the Merger to be fair to and in the best interests of OrCAD and its stockholders and has unanimously approved the Issuance and the Merger Agreement. The OrCAD Board recommends that OrCAD stockholders vote "FOR" the Issuance. The OrCAD Board's recommendation is based upon a number of factors discussed in this Joint Proxy Statement/Prospectus. See "CONFLICTS OF INTEREST." 23 OPINION OF ORCAD FINANCIAL ADVISOR Redwood Partners was retained by OrCAD to evaluate the fairness, from a financial point of view, of the consideration to be offered and paid for MicroSim pursuant to the Merger. On October 13, 1997, in connection with the evaluation of the proposed Merger Agreement, Redwood Partners delivered a written opinion to the OrCAD Board to the effect that, as of the date and based upon and subject to certain matters stated in the Redwood Partners Opinion, the consideration to be paid by OrCAD in the Merger is fair to OrCAD and its stockholders from a financial point of view. No limitations were imposed by the OrCAD Board with respect to the investigations made or the procedures followed by Redwood Partners in rendering the Redwood Partners Opinion. The Redwood Partners Opinion was delivered for the information of the OrCAD Board and is not a recommendation to any OrCAD stockholder as to how such stockholder should vote at any meeting of OrCAD stockholders called to consider matters relating to the Merger and does not address OrCAD's business decision to effect the Merger. In arriving at its opinion, Redwood Partners reviewed certain publicly available business and financial information relating to OrCAD, certain non- public business and financial information relating to OrCAD and MicroSim, and the Merger Agreement. Redwood Partners also reviewed certain other information, including financial forecasts provided to it by OrCAD and MicroSim, and met with management of both OrCAD and MicroSim to discuss the business and prospects of the respective companies. In addition, Redwood Partners considered the value of certain other publicly traded companies, the financial terms of certain other business combinations and other transactions which have recently been effected and also considered the financial effects of the Merger on OrCAD. Furthermore, Redwood Partners considered such other information, financial studies, analyses and investigations, and financial, economic and market data which it deemed relevant. In arriving at its opinion, Redwood Partners assumed and relied upon the accuracy and completeness of the financial and other information used by it without assuming any responsibility for independent verification of such information. Redwood further relied upon the assurances of the managers of both OrCAD and MicroSim that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial forecasts (including, without limitation, projected operational benefits and cost savings arising from the Merger), Redwood Partners assumed that they had been reasonably prepared on bases reflecting the best currently available estimates and judgments of management of OrCAD and MicroSim as to the financial performance of OrCAD and MicroSim. Redwood Partners expressed no view as to such forecasts or the assumptions on which they were based and there cannot be any assurance that actual results of OrCAD or MicroSim will not differ materially from those reflected in the forecasts. In arriving at its opinion, Redwood Partners did not conduct a physical inspection of the properties and facilities of OrCAD or MicroSim, and Redwood Partners did not make nor obtain any evaluations or appraisals of the assets or liabilities of OrCAD or MicroSim. In arriving at its own opinion, upon advice of OrCAD and its legal and accounting advisors, Redwood Partners assumed that the Merger would qualify: (i) for pooling of interests accounting treatment and (ii) as a reorganization within the meaning of the Code, and therefore as a tax-free transaction to the stockholders of OrCAD. Redwood Partners' opinion necessarily was based upon market, economic, and other conditions as they existed on, and could be evaluated as of, the date of the Redwood Partners Opinion. In connection with preparing its presentations to the OrCAD Board on September 24, 1997, and its written opinion dated October 13, 1997, Redwood Partners performed a variety of financial and comparative analyses as summarized below. The preparation of a fairness opinion involves various determinations as to the most appropriate and relevant methods of financial and comparative analysis and the application of those methods to the particular circumstances and, therefore, such an opinion is not readily susceptible to summary description. Furthermore, in arriving at its opinion, Redwood Partners did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each 24 analysis and factor so that the range of valuation resulting from any particular analysis described above should not be taken to be Redwood Partners' view of the actual value of MicroSim. Accordingly, Redwood Partners believes that its analyses must be considered as a whole and that considering any portions of such analyses and factors, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying the Redwood Partners Opinion. In its analyses, Redwood Partners made numerous assumptions with respect to industry performance, general business and economic conditions, and other matters, many of which are beyond the control of OrCAD and MicroSim. Any estimates contained in these analyses are not necessarily indicative of actual values or predictive of future results or values, which may be more or less favorable than as set forth therein. In addition, analyses relating to the value of businesses do not purport to be appraisals or to reflect the prices at which businesses actually may be sold. The generally accepted financial analyses Redwood Partners used in reaching its opinion which it discussed with the OrCAD Board included (i) a relative contribution analysis, which included a comparison of respective financial positions and certain operating results of OrCAD and MicroSim, (ii) a stock trading history, which consisted of reviewing the trading prices for OrCAD Common Stock and a group of comparable companies, (iii) a comparable company analysis, which consisted of reviewing the financial performance of OrCAD, MicroSim and a group of comparable publicly traded companies, (iv) a comparable acquisition analysis, which consisted of reviewing the financial terms of certain other similar transactions recently effected which were considered to be comparable to the Merger, and (v) a discounted cash flow analysis, which consisted of discounting to present value the incremental project cash flows and terminal values anticipated following the Merger. The material portions of these analyses are summarized below. Relative Contribution Analysis. Redwood Partners analyzed the relative contribution of OrCAD and MicroSim across a broad range of financial and operating measures. Utilizing publicly available information for OrCAD and non-public information for MicroSim, Redwood Partners determined the percentage contribution provided by OrCAD and MicroSim of several key financial measures including total revenue, revenue in certain product categories, gross profit, operating profit, net profit, total assets, stockholders' equity, cash, market capitalization and firm value, among others. In addition, Redwood Partners applied a similar analysis to certain key operating measures including installed base of seats and size and age of software library, among others. The analysis indicated a reference range of post-Merger ownership percentage for the MicroSim shareholders of approximately 15% to 35% on a primary basis. Stock Trading History. Redwood Partners considered various historical data concerning the history of trading prices and volumes for OrCAD Common Stock for the period from February 29, 1996 (the date of the initial public offering of OrCAD) to October 10, 1997 (the last trading day prior to delivery of the Redwood Partners Opinion) and the relative stock prices during this same period of OrCAD and of selected companies in the EDA industry considered by Redwood Partners to be comparable to OrCAD and MicroSim. Specifically, Redwood Partners included in its review Analogy, Avant!, Cadence Design Systems, Mentor Graphics, Synopsys, Technology Modeling Associates, and Viewlogic Systems (the "EDA Group"). During this period, the closing stock price of OrCAD ranged from $6.13 to $16.25 per share. Comparable Company Analysis. Using publicly available information, Redwood Partners compared selected financial data of OrCAD and MicroSim with similar data in the EDA Group. For each of OrCAD, MicroSim and the EDA Group, Redwood Partners calculated the multiple of valuation to (i) the 1996 revenue (the "1996 Revenue Multiple") and (ii) the 1996 earnings per share (the "1996 P/E Multiple"), based on data from Zaks Investment Research, a service company widely used by the investment community to gather earnings estimates from various research analysts. Redwood Partners noted that, as of October 9, 1997, (i) the 1996 Revenue Multiple for MicroSim (based on the exchange ratio) was 1.4x versus 2.9x for OrCAD and 4.8x for the mean of the EDA Group, excluding the high and low multiples, and (ii) the 1996 P/E Multiple for MicroSim was 20.6x (based on the exchange ratio) versus 18.2x for OrCAD and 42.7x for the mean of the EDA Group, excluding the high and low multiples. 25 Comparable Acquisition Analysis. Redwood Partners reviewed selected acquisitions completed during the last two years with total consideration between $10 million and $450 million across the EDA industry. Only a few transactions completed during this time period were directly comparable to the Merger. As such, a broader sample of precedent transactions was selected for comparative purposes. Redwood Partners analyzed the ratios of consideration paid to revenue. Reference range and average for the ratio were 5x to 20x (average of 10.6x). Discounted Cash Flow Analysis. Redwood Partners analyzed the incremental cash flows projected for the combined operations of OrCAD post-Merger relative to cash flows projected for the operations of OrCAD on a stand-alone basis. These analyses were based on the financial projections for stand-alone operations provided by management of OrCAD and MicroSim and a combined company cash forecast jointly prepared by management of OrCAD and MicroSim for each of the four (4) years ended December 31, 1997 to 2000. Redwood Partners derived the incremental free cash flow and discounted this cash flow to present values, applying discount rates ranging from 15% to 30%. To approximate the perpetual value of the incremental cash flow stream in 2000, Redwood Partners applied terminal multiples of 15x to 30x free cash flow in 2000. Based on the foregoing analysis, Redwood Partners derived a reference range of value for the incremental cash flows projected for the combined company relative to the cash flows projected for OrCAD on a stand-alone basis, from $28 million to $48 million. The summary set forth in this section does not purport to be a complete description of Redwood Partners' analyses. The full text of the Redwood Partners Opinion, dated October 13, 1997, which sets forth the assumptions made, procedures followed, matters considered, limitations on and the scope of the review of Redwood Partners in rendering its opinion, is attached as Appendix B to this Joint Proxy Statement/Prospectus. OrCAD stockholders are urged to read the Redwood Partners Opinion in its entirety. This summary of the Redwood Partners Opinion is qualified in its entirety by reference to the full text of such opinion. Pursuant to an engagement letter with OrCAD, Redwood Partners will receive a fee of $200,000 for the Redwood Partners Opinion and certain services rendered in conjunction with the Merger, of which $50,000 is not contingent upon consummation of the Merger. OrCAD will also reimburse Redwood Partners for its out-of-pocket expenses, including reasonable fees and disbursements of counsel. OrCAD has also agreed to indemnify Redwood Partners and its affiliates, directors, officers, partners, agents, and employees, and each person, if any, controlling Redwood Partners or any of its affiliates against certain liabilities, including certain liabilities under the federal securities laws, relating to or arising out of its engagement. John C. Savage, a Principal of Redwood Partners, is a member of the OrCAD Board and will continue to so serve after consummation of the Merger. As of October 16, 1997, Mr. Savage owned options to acquire 10,000 shares of OrCAD Common Stock and Principals of Redwood Partners, including Mr. Savage, owned an aggregate of 31,724 shares of OrCAD Common Stock. A predecessor of Redwood Partners was the largest stockholder of OrCAD until September 1996. Redwood Partners is a venture capital and investment banking firm, specializing in the information technology industry. As such, it provides advice on transactions, such as the Merger, and engages in valuations of businesses and their securities in connection with investments for its own account and with mergers and acquisitions. The OrCAD Board selected Redwood Partners to act as its financial advisor on the basis of Redwood Partners' reputation, its prior merger and acquisition experience, and its prior involvement with and familiarity with OrCAD and the EDA industry. RECOMMENDATION OF MICROSIM BOARD The MicroSim Board has determined the Merger to be fair to and in the best interests of MicroSim and its shareholders and has approved the Merger Agreement and the Merger. The MicroSim Board recommends that MicroSim shareholders vote "FOR" the Merger Agreement and the Merger. The MicroSim Board's recommendation is based upon a number of factors discussed in this Joint Proxy Statement/Prospectus. See "CONFLICTS OF INTEREST." 26 THE MERGER The description of the Merger Agreement set forth below does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement a copy of which is attached as Appendix A to this Joint Proxy Statement/Prospectus and incorporated by reference herein. TERMS OF THE MERGER The Merger. Subject to the terms and conditions of the Merger Agreement, Merger Sub will merge with and into MicroSim at the Effective Time. The separate corporate existence of Merger Sub will then cease, and MicroSim will be the surviving corporation in the Merger (the "Surviving Corporation") and will become a wholly owned subsidiary of OrCAD. Articles of Incorporation and Bylaws. The Merger Agreement provides that the Articles of Incorporation of MicroSim as in effect immediately prior to the Effective Time will become the Articles of Incorporation of the Surviving Corporation. The Bylaws of MicroSim as in effect immediately prior to the Effective Time will become the Bylaws of the Surviving Corporation. Directors and Officers. The directors of Merger Sub immediately prior to the Effective Time will become the directors of the Surviving Corporation, until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal. OrCAD has agreed to expand its Board by two members. The first such expansion will be effective as of the first Board meeting following the Effective Time, and OrCAD has agreed to cause its Board to elect Wolfram H. Blume, currently Chairman of the Board, President and Chief Executive Officer of MicroSim, to fill that position, effective with that meeting. Each new director of OrCAD will serve until his or her successor has been duly elected or appointed and qualified or until his or her earlier death, resignation or removal. The officers of Merger Sub immediately prior to the Effective Time will become the officers of the Surviving Corporation, until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal. The OrCAD Board will elect Mr. Blume and Michael U. Wimbrow, effective as of the Effective Time, as Chief Technical Officer and Senior Vice President of Research and Development, and as Vice President of Product Strategy and Architecture, respectively, of OrCAD. See "THE MERGER--Management and Operations of MicroSim After the Merger." Conversion of MicroSim Stock and Options to Acquire Shares of MicroSim Stock in the Merger. At the Effective Time, all shares of MicroSim Stock issued and outstanding immediately prior to the Effective Time (other than shares as to which dissenters' rights of appraisal have been duly sought, perfected and are not subsequently withdrawn), and all options to acquire shares of MicroSim Stock outstanding immediately prior to the Effective Time, will be exchanged for OrCAD Common Stock. The 2,697,795 issued and outstanding fully vested shares of MicroSim Stock (including vested shares held under strict purchase agreements) will each be exchanged for .825 shares of OrCAD Common Stock, for an aggregate total of 2,225,680 shares of OrCAD Common Stock (subject to adjustment for fractional shares). The 106,820 shares of unvested MicroSim Stock held under stock purchase agreements will each be valued at .91 shares of fully vested MicroSim Stock, and then the discounted shares exchanged for .825 shares of OrCAD Common Stock, for an aggregate total of 80,195 shares of OrCAD Common Stock (subject to adjustment for fractional shares). The options to acquire 95,640 shares of MicroSim Stock underlying fully vested stock options will be valued by subtracting the exercise price of each option from the "MicroSim Fair Market Value." That value will be determined as .825 times the "OrCAD Fair Market Value." The resulting dollar value shall be divided by the OrCAD Fair Market Value, and the underlying fully vested stock option shall then be exchanged for that number of shares of OrCAD Common Stock (subject to adjustments for fractional shares and for variations in the OrCAD Fair Market Value). The options to acquire 228,760 shares of MicroSim Stock underlying unvested stock options will be valued as the fully vested options are valued, except the total value shall be multiplied by .90, to reflect the discounted value of unvested options (subject to adjustment for fractional shares and for variations in the OrCAD Fair Market Value). The foregoing numbers for shares and options may fluctuate based upon option exercises and other events prior to the Effective Time. Adjustments. If, prior to the Effective Time, OrCAD should split or combine the OrCAD Common Stock, or pay a stock dividend or other stock distribution in OrCAD Common Stock, or otherwise change the OrCAD Common Stock into any other securities, or make any other dividend on or distribution of the OrCAD Common 27 Stock, then the exchange ratio will be appropriately adjusted to reflect such split, combination, dividend or other distribution or change. Fractional Shares. No fractional shares of OrCAD Common Stock will be issued in the Merger. OrCAD will pay to each holder of MicroSim Stock or options to acquire shares of MicroSim Stock an amount in cash (rounded to the nearest whole cent) determined by multiplying (i) the fair market value of a share of OrCAD Common Stock by (ii) the fraction of a share of OrCAD Common Stock which such holder would otherwise be entitled to receive in connection with the Merger. EFFECTIVE TIME OF THE MERGER Promptly following receipt of all required governmental approvals and satisfaction or waiver of the other conditions to the Merger, the Merger will be consummated and become effective at the time at which the articles of merger to be filed pursuant to the Corporations Code and the articles of merger to be filed pursuant to the Business Corporation Act are accepted for filing by the Secretary of State of California and the Secretary of State of Oregon or such later date and time as may be specified in such articles of merger. See "THE MERGER--Conditions; Waivers." EXCHANGE OF MICROSIM STOCK AND OPTIONS TO ACQUIRE SHARES OF MICROSIM STOCK Prior to the Effective Time, OrCAD will select ChaseMellon Shareholder Services, LLC or such other person or persons reasonably satisfactory to MicroSim to act as exchange agent for the Merger (the "Exchange Agent"). As soon as practicable after the Effective Time, (i) the Exchange Agent will deliver to each holder of certificates representing shares of MicroSim Stock (other than dissenting shares) and each holder of options to acquire shares of MicroSim Stock, a form letter of transmittal and instruction for use in effecting the surrender of such certificates and options for conversion into shares of OrCAD Common Stock and (ii) OrCAD will make available, and the holders of MicroSim Stock (other than dissenting shares) and the holders of options to acquire shares of MicroSim Stock will be entitled to receive, upon surrender to the Exchange Agent of one or more certificates representing shares of MicroSim Stock or options to acquire shares of MicroSim Stock for cancellation and such other documents reasonably requested by the Exchange Agent, certificates representing the number of shares of OrCAD Common Stock into which such holder's MicroSim Stock or options to acquire shares of MicroSim Stock is converted in the Merger, less shares to be delivered to the Escrow Agent pursuant to the Escrow Agreement. After the Effective Time, certificates representing MicroSim Stock (other than dissenting shares) and options to acquire shares of MicroSim Stock will represent solely the right to receive OrCAD Common Stock. ESCROW OF ORCAD COMMON STOCK The Merger Agreement provides that OrCAD will withhold on a pro rata basis ten percent (10%) of the shares of OrCAD Common Stock to be received by each holder of MicroSim Stock or options to acquire shares of MicroSim Stock upon consummation of the Merger (the "Escrow Shares"). The Escrow Shares will be delivered to First Trust National Association as escrow agent (the "Escrow Agent"). The Escrow Shares will be held by the Escrow Agent for a period, that, absent unresolved claims, will end on the first anniversary of the Closing Date. The Escrow Shares will be subject to claims by OrCAD to satisfy MicroSim's obligations under the Merger Agreement to reimburse OrCAD for any and all losses, damages, liabilities, costs and expenses incurred by OrCAD by reason of, arising out of or in connection with any breach or inaccuracy of any representation or warranty of MicroSim contained in the Merger Agreement or the failure by MicroSim to perform any agreement or covenant required of MicroSim under the Merger Agreement. For this purpose, the Escrow Shares will be valued at the OrCAD Fair Market Value. Wolfram H. Blume, Bruce A. Warren and Louis A.

IRREVOCABLE PROXY The principal shareholder of MicroSim, owning an aggregate of 2,165,725 shares of MicroSim Stock and representing approximately 77% of all outstanding shares of MicroSim Stock as of October 16, 1997, has given an irrevocable proxy to OrCAD to vote all of his shares of MicroSim Stock for approval of the Merger Agreement and the Merger. NO SOLICITATION Under the Merger Agreement, MicroSim has agreed that it will not, nor will it permit any of its officers, directors, employees, agents, or representatives (including, without limitation, investment bankers, attorneys and accountants), directly or indirectly to, (i) initiate, contract with, solicit or encourage any inquiries or proposals by, or (ii) enter into any discussions or negotiations with, or disclose directly or indirectly any information concerning its business and properties to, or afford any access to its properties, books, and records to, any corporation, partnership, person, or other entity or group in connection with any possible proposal (an "Acquisition Proposal") regarding a sale of MicroSim's capital stock or a merger, consolidation, or sale of all or a substantial portion of its assets, or any similar transaction; provided, however, that notwithstanding the foregoing, if the MicroSim Board receives a written Acquisition Proposal, and in the MicroSim Board's opinion (after consultation with MicroSim's legal counsel), the failure to consider such Acquisition Proposal would cause the MicroSim Board to violate its fiduciary duties under the Corporations Code, then the MicroSim Board may consider and act with respect to such Acquisition Proposal to the extent required to fulfill its fiduciary duties. MicroSim will provide written notice to OrCAD immediately if any discussions or negotiations are sought to be initiated, any inquiry or proposal is made, or any such information is requested with respect to an Acquisition Proposal or potential Acquisition Proposal or if any Acquisition Proposal is received or indicated to be forthcoming.

INDEMNIFICATION MicroSim has agreed to indemnify and hold harmless OrCAD and Merger Sub from and against and will reimburse OrCAD and Merger Sub with respect to all claims, losses, damages, liabilities, judgments, settlements, costs and expenses (including reasonable attorneys' fees) ("Indemnifiable Damages") incurred by OrCAD and/or Merger Sub by reason of or arising out of or in connection with the breach or inaccuracy of any representation or warranty of MicroSim contained in the Merger Agreement or the failure of MicroSim to perform any agreement or covenant required by the Merger Agreement to be performed by it. The Merger Agreement provides that MicroSim will not be liable for or with respect to the first $300,000 of the aggregate of Indemnifiable Damages, nor any individual claim that is for less than $5,000, and the total liability shall not exceed the total value of the Escrow Shares. 34 CERTAIN FEDERAL INCOME TAX CONSIDERATIONS The following discussion summarizes the material federal income tax considerations of the Merger that are generally applicable to holders of MicroSim Stock, and does not purport to be a complete analysis or listing of all potential tax effects relevant to a decision whether to vote in favor of approval and adoption of the Merger. This section reflects the tax opinion of Ater Wynne Hewitt Dodson & Skerritt, LLP, which will be delivered to MicroSim in connection with the Merger and will be filed as an exhibit to a supplement to the Registration Statement of which this Joint Proxy Statement/Prospectus is a part (the "Tax Opinion"). The Tax Opinion includes an opinion to the effect that the Merger will be treated as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"), that each of OrCAD, Merger Sub and MicroSim will be a party to the reorganization within the meaning of Section 368(a) of the Code, and that no gain or loss will be recognized by the MicroSim shareholders as a result of the Merger with respect to the outstanding MicroSim Stock converted into shares of OrCAD Common Stock or as a result of the return of the Escrow Shares to OrCAD. The Tax Opinion is based on certain assumptions, including the assumption that the Merger will take place as described in the Merger Agreement, and is subject to certain limitations and qualifications. The Tax Opinion is also based on the assumption that certain factual matters represented by OrCAD, Merger Sub, MicroSim and others will be true and correct at the Effective Time, which representations tax counsel will neither investigate nor verify. Of particular importance will be factual representations made by certain holders of MicroSim Stock relevant to satisfaction of the "continuity of interest" requirement. To satisfy the continuity of interest requirement, MicroSim shareholders must not, pursuant to a plan or intent existing at or prior to the Effective Time of the Merger, dispose of or transfer so much of either (i) their capital stock of MicroSim in anticipation of the Merger, or (ii) the OrCAD Common Stock to be received in the Merger (collectively, "Planned Dispositions"), such that the MicroSim shareholders, as a group, would no longer have a significant equity interest in the MicroSim business being conducted by OrCAD after the Merger. Planned Dispositions include, among other things, shares disposed of pursuant to dissenters' rights. While case law may support a lesser percentage, the continuity of interest requirement will be met as long as MicroSim shareholders do not have a plan or intention to sell, exchange or otherwise dispose of a number of shares of OrCAD Common Stock received in the Merger (taking all Planned Dispositions into account) that would reduce the number of shares of OrCAD Common Stock owned by such shareholders after the Merger to a number of shares having a value as of the date of the Merger less than 50% of the value of all the formerly outstanding shares of MicroSim Stock held by such shareholders as of that date. If the continuity of interest requirement is not satisfied, the Merger would not be treated as a "reorganization." MICROSIM SHAREHOLDERS AND OPTION HOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER, INCLUDING THE APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE MERGER. Subject to the limitations and qualifications described herein and in the Tax Opinion, the Merger qualifies as a reorganization within the meaning of Section 368 of the Code, and the following tax consequences will result: (a) No gain or loss will be recognized by holders of the MicroSim Stock upon their receipt in the Merger of OrCAD Common Stock in exchange therefor (except to the extent of cash received in lieu of fractional shares or as a result of exercising dissenters' rights) or as a result of the return of the Escrow Shares to OrCAD; and (b) The aggregate tax basis of the OrCAD Common Stock received by MicroSim shareholders in the Merger will be the same as the aggregate tax basis of MicroSim Stock surrendered in exchange therefor. Neither OrCAD nor MicroSim has requested or will request a ruling from the Internal Revenue Service ("IRS") with regard to any of the U.S. federal income tax consequences of the Merger. A successful IRS 35 challenge to the "reorganization" status of the Merger would result in a MicroSim shareholder recognizing gain or loss with respect to each share of MicroSim Stock surrendered equal to the difference between the shareholder's basis in such share and the fair market value, at the Effective Time, of the OrCAD Common Stock received in exchange therefor. In such event, a shareholder's aggregate basis in the OrCAD Common Stock so received would equal its fair market value, and the holding period for such stock would begin the day after the Merger. THE FOREGOING DISCUSSION IS INTENDED ONLY AS A SUMMARY OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER AND DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OR LISTING OF ALL POTENTIAL TAX EFFECTS RELEVANT TO A DECISION WHETHER TO VOTE IN FAVOR OF APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND THE MERGER. THE DISCUSSION DOES NOT ADDRESS THE TAX CONSEQUENCES THAT MAY BE RELEVANT TO A PARTICULAR MICROSIM SHAREHOLDER SUBJECT TO SPECIAL TREATMENT UNDER CERTAIN FEDERAL INCOME TAX LAWS, SUCH AS DEALERS IN SECURITIES, BANKS, INSURANCE COMPANIES, TAX-EXEMPT ORGANIZATIONS, NON-UNITED STATES PERSONS, SHAREHOLDERS SUBJECT TO THE ALTERNATIVE MINIMUM TAX PROVISIONS OF THE CODE AND SHAREHOLDERS WHO ACQUIRED THEIR SHARES OF MICROSIM COMMON STOCK PURSUANT TO THE EXERCISE OF MICROSIM STOCK OPTIONS OR OTHERWISE AS COMPENSATION, NOR DOES IT ADDRESS ANY CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCALITY OR FOREIGN JURISDICTION OR THE TAX CONSEQUENCES OF TRANSACTIONS EFFECTUATED PRIOR TO OR AFTER THE MERGER (WHETHER OR NOT SUCH TRANSACTIONS ARE IN CONNECTION WITH THE MERGER), INCLUDING WITHOUT LIMITATION TRANSACTIONS IN WHICH SHARES OF MICROSIM STOCK ARE ACQUIRED OR IN WHICH SHARES OF ORCAD COMMON STOCK ARE DISPOSED. MOREOVER, THE TAX CONSEQUENCES TO HOLDERS OF MICROSIM STOCK OPTIONS ARE NOT DISCUSSED. THE DISCUSSION IS BASED UPON THE CODE, TREASURY REGULATIONS THEREUNDER AND ADMINISTRATIVE RULINGS AND COURT DECISIONS AS OF THE DATE HEREOF. ALL OF THE FOREGOING ARE SUBJECT TO CHANGE (WHICH CHANGE COULD BE RETROACTIVE), AND ANY SUCH CHANGE COULD AFFECT THE CONTINUING VALIDITY OF THIS DISCUSSION. MICROSIM SHAREHOLDERS SHOULD BE AWARE THAT OPINIONS OF COUNSEL ARE NOT BINDING ON THE IRS OR ANY COURT; IF THE MERGER FAILS TO QUALIFY AS A TAX- FREE REORGANIZATION, IT WOULD BE TREATED FOR FEDERAL INCOME TAX PURPOSES AS A TAXABLE SALE BY THE MICROSIM SHAREHOLDERS OF THEIR MICROSIM STOCK. MICROSIM SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS CONCERNING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE MERGER TO THEM. RESALE OF ORCAD COMMON SHARES ISSUED IN THE MERGER; AFFILIATES The OrCAD Common Stock to be issued to MicroSim shareholders and option holders in connection with the Merger will be freely transferable under the Securities Act, except for OrCAD Common Stock issued to any person deemed to be an affiliate of MicroSim for purposes of Rule 145 under the Securities Act at the Effective Time ("Affiliates"). Affiliates may not sell their OrCAD Common Stock acquired in connection with the Merger except in compliance with Rule 145 promulgated under the Securities Act. MicroSim has delivered a disclosure statement to OrCAD identifying all persons who may be deemed to be Affiliates. Each Affiliate listed in that disclosure statement has agreed not to sell, transfer or otherwise dispose of any OrCAD Common Stock received in the Merger in violation of the Securities Act, and that such Affiliate will not, after the earlier of (i) the mailing of this Joint Proxy Statement/Prospectus and (ii) the thirtieth day prior to the Effective Time, sell any OrCAD Common Stock or any shares of MicroSim Stock or otherwise reduce such Affiliate's risk relative to any OrCAD Common Stock until after such time as consolidated financial statements which reflect at least 30 days of post-Merger operations have been published by OrCAD, except as permitted by Staff Accounting Bulletin No. 76 issued by the Commission. See "THE MERGER-- Accounting Treatment." 36 ACCOUNTING TREATMENT It is expected that the Merger will be treated as a pooling of interests for accounting and financial reporting purposes. See "THE MERGER--Conditions; Waivers." MANAGEMENT AND OPERATIONS OF MICROSIM AFTER THE MERGER After the Merger, the articles of incorporation and bylaws of MicroSim will be the Articles of Incorporation and Bylaws of MicroSim as the Surviving Corporation and MicroSim will be a wholly owned subsidiary of OrCAD. MicroSim will operate as one of OrCAD's business units, and OrCAD currently intends to maintain MicroSim's corporate headquarters in Irvine, California. After the Merger, MicroSim will have access to resources generally available to OrCAD's other business units, will participate in appropriate activities with other OrCAD business units and will operate under the direction and guidance of OrCAD's senior management and the OrCAD and MicroSim Boards. EXPENSES AND FEES OrCAD and MicroSim will each pay their own expenses in connection with the Merger. RIGHTS OF DISSENTING MICROSIM SHAREHOLDERS The rights of MicroSim shareholders who dissent in connection with the Merger are governed by specific legal provisions contained in Chapter 13 ((S)1300--1312) of the Corporations Code. The following is a brief summary of the rights of shareholders of MicroSim who dissent from the Merger. It is qualified in its entirety by reference to the applicable statutory provisions of the Corporations Code attached hereto as Appendix C. If the Merger is consummated, holders of record of MicroSim Stock who (a) deliver to MicroSim written demand for the purchase of their shares within 30 days after the date on which MicroSim mailed to the shareholder the notice of approval of the Merger by MicroSim's outstanding shares, (b) refrain from voting in favor of the Merger, and (c) comply with the provisions of Sections 1300 through 1312 of the Corporations Code, will then be entitled to have the "fair market value" of their shares, determined as of the day before the first announcement of the terms of the proposed Merger, paid to them in cash. The written demand must contain a statement of the number and class of the shares held of record by the shareholder which the shareholder demands that MicroSim purchase, and a statement of what the shareholder claims is the fair market value of those shares as of the day before the announcement of the Merger, excluding any appreciation or depreciation due to the proposed Merger. MicroSim deems the announcement of the Merger for these purposes to have occurred on October 13, 1997. The following is a brief summary of Sections 1300 through 1312 of the Corporations Code, which sets forth the procedures for demanding statutory dissenters' rights. This summary is qualified in its entirety by reference to Sections 1300 through 1312 of the Corporations Code, the text of which is attached hereto in Appendix C. If the Merger is approved and consummated, those shareholders of MicroSim who elect to exercise their dissenters' rights and who properly and timely perfect such rights will be entitled to receive the "fair market value" in cash for their shares of MicroSim Stock. Pursuant to Section 1300 of the Corporations Code, such "fair market value" means the value of the MicroSim shares as of the day before the first announcement of the terms of the proposed Merger, excluding any appreciation or depreciation in consequence of the proposed Merger, and adjusted for any stock split, reverse stock split or share dividend which becomes effective after the Merger. If any shareholder has the right to exercise dissenters' rights, MicroSim must, within ten (10) days after approval of the Merger by the outstanding shares, deliver to all such shareholders: notice of the approval of the Merger accompanied by a copy of Sections 1300, 1301, 1302, 1303 and 1304 of the Corporations Code; a statement of the price determined by MicroSim to represent the "fair market value" of the dissenting shares; 37 and, a brief description of the procedure to be followed if the shareholder desires to exercise the shareholder's dissenters' right under the Corporations Code (the "Dissenters' Notice"). A shareholder who elects to exercise his or her dissenters' rights must (i) be the record holder of the dissenting shares as of the MicroSim Record Date, (ii) deliver to MicroSim within 30 days after the date on which the Dissenters' Notice was mailed to the shareholder written demand for the purchase of the shares and payment in cash of their fair market value, which written demand must contain a statement of the number and class of shares held of record by the shareholder which the shareholder demands that MicroSim purchase, and a statement of what the shareholder claims is the fair market value of those shares as of the day before the announcement of the Merger, excluding any appreciation or depreciation because of the proposed Merger, (iii) deliver to MicroSim the share certificate or certificates, and (iv) must not have voted his or her shares in favor of the Merger. If a shareholder fails to deliver the written demand for payment to MicroSim within 30 days after the date on which the Dissenters' Notice was mailed to the shareholder, or if the shareholder votes his or her shares in favor of the Merger, such shareholder will lose his or her dissenters' rights with respect to his or her shares. Within 30 days after the later of consummation of the Merger or an agreement between MicroSim and the dissenting shareholder as to the "fair market value" of the shares to be purchased, MicroSim shall pay each shareholder cash in the amount of the "fair market value" of the shares to be repurchased plus statutory interest accrued from the date of the agreement as to the "fair market value" of the shares. If the shareholder and MicroSim cannot agree on the "fair market value" of the shares to be repurchased, then within six (6) months after the date on which the Dissenters' Notice was mailed to the shareholder (but not thereafter), the shareholder may file a complaint in the superior court of the proper county asking the court to determine the "fair market value" of the dissenting shares. The dissenter will be entitled to judgment for the amount that the court or an appraiser appointed by the court finds to be the "fair market value" of his or her shares. The Merger Agreement provides that it may be terminated by OrCAD or MicroSim in the event that more than six percent (6%) of the outstanding shares of MicroSim Stock are dissenting shares. CONFLICTS OF INTEREST MicroSim Board of Directors and Management. As of the Record Date, non- employee directors of the MicroSim Board beneficially owned an aggregate of 125,000 shares of MicroSim Stock and held options to acquire an aggregate of 60,000 shares of MicroSim Stock, exercisable at prices ranging from $3.40 to $3.60 per share. See "STOCK OWNED BY MICROSIM MANAGEMENT AND PRINCIPAL SHAREHOLDERS." Assuming an OrCAD market value of $8.94, the aggregate dollar value of OrCAD Common Stock to be received by these non-employee directors in respect of outstanding shares of MicroSim Stock would be approximately $921,680, representing approximately 4.5% of the aggregate consideration to be received by all holders of MicroSim Stock. Assuming an OrCAD market value of $8.94, the aggregate dollar value of OrCAD Common Stock to be received by these non-employee directors in respect of outstanding options to acquire MicroSim Stock would be approximately $209,611, representing approximately 18.0% of the aggregate consideration to be received by all holders of options to acquire shares of MicroSim Stock. As of the Record Date, the executive officers of MicroSim beneficially owned an aggregate of 2,227,725 shares of MicroSim Stock and held options to acquire an aggregate of 105,000 shares of MicroSim Stock, exercisable at prices ranging from $3.40 to $3.60 per share. See "STOCK OWNED BY MICROSIM MANAGEMENT AND PRINCIPAL SHAREHOLDERS." Assuming an OrCAD market value of $8.94, the aggregate dollar value of OrCAD Common Stock to be received by these executive officers in respect of outstanding shares of MicroSim Stock would be approximately $16,421,014, representing approximately 79.7% 38 of the aggregate consideration to be received by all holders of MicroSim Stock. Pursuant to the Merger Agreement, all outstanding options to acquire shares of MicroSim Stock, including those held by the executive officers of MicroSim, will be converted into shares of OrCAD Common Stock. Assuming an OrCAD market value of $8.94, the aggregate dollar value of OrCAD Common Stock to be received by these executive officers in respect of outstanding options to acquire shares of MicroSim Stock would be approximately $392,910, representing approximately 33.8% of the aggregate consideration to be received by all holders of options to acquire shares of MicroSim Stock.

At that value, 2,436,354 shares of OrCAD Common Stock would be exchanged for 2,697,795 shares of MicroSim Stock; 106,820 shares of unvested MicroSim Stock held under stock purchase agreements; 95,640 shares of MicroSim Stock underlying fully vested stock options; and 228,760 shares of MicroSim Stock underlying unvested stock options. The actual number of shares of OrCAD Common Stock to be issued will be determined at the Closing Date of the Merger based on the average closing price of OrCAD Common Stock for the ten (10) consecutive trading days ending with the close of trading on the third business day preceding the Closing Date. NOTE 2.--PRO FORMA EARNINGS PER SHARE Net income per common and common equivalent share amounts are based on the weighted average number of common shares outstanding and dilutive common equivalent shares assumed to be outstanding during the period using the treasury stock method, giving effect to the Merger as if it had been consummated at the beginning of the years presented given the assumptions described in Note 1. NOTE 3.--TRANSACTION COSTS OrCAD and MicroSim estimate that they will incur direct and indirect costs of $2.5 million in connection with the Merger, relating mainly to financial advisory fees, legal and accounting services for both parties, personnel severance costs, the cancellation and continuation of contractual obligations and other integration costs. These nonrecurring costs will be charged to operations in the fiscal quarter in which the Merger is consummated. The Unaudited Pro Forma Combined Condensed Balance Sheet reflects these estimated transaction costs and their tax effects as if such costs were incurred as of June 30, 1997, but the effect of these costs are not reflected in the Unaudited Pro Forma Combined Condensed Statement of Operations. NOTE 4.--CONFORMING ADJUSTMENTS AND INTERCOMPANY TRANSACTIONS There have been no adjustments required to conform the accounting policies of the combined company. Intercompany transactions, reflecting a licensing agreement between MicroSim and Massteck, a wholly-owned subsidiary of OrCAD, during the years presented and the resulting royalty receivable and other current liabilities, are eliminated under the column heading "Pro Forma-- Adjustments". 44 BUSINESS OF ORCAD OVERVIEW OrCAD develops, markets and supports Microsoft Windows-based electronic design automation ("EDA") software products that assist electronics designers in designing printed circuit boards ("PCBs"), field-programmable gate arrays ("FPGAs") and complex programmable logic devices ("CPLDs"). PCBs, FPGAs and CPLDs are found in a majority of today's electronic products, and are often referred to as "mainstream" components. OrCAD's products enable electronics designers working on personal computers ("PCs") to reduce time to market, improve product capability, and reduce design costs. OrCAD's Windows-based EDA solutions support the design process for mainstream components, from schematic capture to programmable logic design and verification to printed circuit board layout. Over 200,000 products bearing the OrCAD name have been sold worldwide since 1986. INDUSTRY BACKGROUND During the last two decades, there has been considerable growth in a wide variety of electronics markets, including those for telecommunications equipment, computers, and consumer electronics products. According to a 1995 report from market research firm Dataquest, the broad electronic equipment market is expected to reach $1 trillion by 1998. Advances in electronics technology have enabled the development of products with significantly greater functionality, lower cost, and smaller size. The electronic functionality of these products today is contained in multiple, diverse integrated circuits ("ICs") combined into electronic subsystems on one or more PCBs. While extremely complex components such as microprocessors, memory, and custom digital signal processors are central to a number of these subsystems, most subsystems are primarily composed of mainstream components. Competitive pressures and the proliferation of programmable logic devices and PCBs in product design have led to increasing demand for lower cost, easier-to-use solutions for design engineers creating mainstream components. The complexity of FPGAs and PCBs is continuously increasing as electronics manufacturers seek to increase functionality and reduce product cost and size. This increasing complexity is demonstrated by comparing today's mainstream designs to those of twenty years ago. Early programmable devices typically contained fewer than 100 gates, had speeds of less than 20 MHz, and required power at 5 volts. Today's mainstream FPGAs are full-scale systems on chips, typically ranging in size from a few thousand to 20,000 gates and operating at 50 to 100 MHz and 3.3 volts. Similarly, twenty years ago, PCBs were typically double-sided boards with a few hundred components, and ran at relatively low speeds. Today's mainstream PCBs may be multi-layer boards containing up to a thousand components and driven by high speed (> 50 MHz) microprocessors. OrCAD believes that the majority of manufacturers' electronic design-starts today involve these mainstream types of FPGAs, CPLDs, and PCBs. Today's Intel PCs running Windows are increasingly powerful and easy to use, and are ideal for most of today's electronics design activities. PRODUCTS OrCAD's Design Desktop for Windows is a family of products designed as 32- bit applications, each of which operates in an integrated fashion with other applications for Microsoft Windows. OrCAD Capture for Windows is a 32-bit schematic capture tool that enables the acceleration of the engineer's overall design process for both FPGA and PCB design. Its integrated design management tools allow design engineers to browse their schematic database to find and edit objects, and to reuse portions of their designs. OrCAD Capture for Windows includes: (i) a schematic editor designed to speed the drawing of complex schematics; (ii) a part editor that allows designers to modify any of the more than 20,000 included parts, or to create new ones easily; (iii) an electrical rules checking program that detects and flags common design errors on the schematic page; and (iv) features to produce output such as netlists, bills of materials and design documentation. Capture Enterprise Edition adds to Capture a design data and library management tool. This tool links parts placed in an OrCAD Capture for Windows design with the information in the manufacturers' internal part 45 databases, which increases the ease and efficiency of part selection for the designer and transfers all information necessary to create correct bills of material and netlists to capture schematics. OrCAD Simulate for Windows is a gate-level simulator developed specifically for FPGA design. It supports the architecture of leading FPGA and CPLD vendors, including among others Actel, Altera, Lattice Semiconductor, Lucent Technologies, Vantis and Xilinx. OrCAD Simulate for Windows supports industry standards for data exchange including VHDL (VITAL/SDF), Open PLA and EDIF 2 0 0, and direct import of Xilinx XNF, which in turn provides for complete logic and timing simulation for popular FPGAs and ensures reusability of design data. The OrCAD Layout for Windows family of products allows rapid completion of most mainstream PCBs. OrCAD Layout for Windows' 16-layer autorouter applies proprietary "push and shove" technology to enable high density routing. OrCAD's interactive routing gives design engineers the power of "user- assisted" autorouting to precisely control critical routes. OrCAD Layout Plus for Windows adds shape-based autorouting, automatic cluster placement, component push-and-shove, auto-interactive placement, auto-path completion and single-layer autorouting. OrCAD Layout Engineers' Edition for Windows is suitable for use by engineers, PCB designers and technicians who do not require an autorouter. OrCAD Express for Windows is an integrated design environment for the design of FPGAs and CPLDs. It integrates VHDL, schematic, and mixed-mode design entry, simulation and synthesis into a single application. With OrCAD Express for Windows, engineers can design board-level systems with FPGAs and CPLDs from OrCAD Solution Partners Actel, Altera, Lattice Semiconductor, Lucent Technologies, Vantis and Xilinx. OrCAD's integrated solutions address the entire process for designing PCBs and programmable logic devices. OrCAD's products are intended to be intuitive and relatively easy to use by a broad range of electronics designers. OrCAD's products include on-line help and tutorials to help design engineers become productive quickly, often within just a few days. In addition, OrCAD's products feature a familiar Windows user interface and can be used with other Windows applications, such as Microsoft Word and Microsoft Excel. This eliminates the need for separate platforms for design and office automation applications. In addition, OrCAD software can be linked to place-and-route software from the leading vendors of programmable logic. OrCAD believes that the EDA market is at the beginning of a trend toward greater use of the Microsoft Windows operating systems, and anticipates that the use of Windows-based products in such market will grow and expand. Accordingly, all of the new products introduced by OrCAD during its preceding and current fiscal year, and all of the products OrCAD is currently developing, are designed for use on Microsoft's Windows NT and Windows 95 operating systems. Any factor adversely affecting the demand for, or use of, the Microsoft Windows operating systems, for EDA applications or in general, could result in a material adverse effect on OrCAD's business, financial condition and results of operations. Software products as complex as those offered by OrCAD may contain defects or failures when introduced or when new versions are released. OrCAD has in the past discovered software defects in certain of its products and may experience delays or lost revenue to correct such defects in the future. There can be no assurance that, despite testing by OrCAD, errors will not be found in new products or versions after commencement of commercial shipments, resulting in loss of market share or failure to achieve market acceptance. Any such occurrence could have a material adverse effect upon OrCAD's business, financial condition or results of operations. MARKETING AND SALES OrCAD markets and sells its products in North America directly through its marketing and telesales organizations, which are supplemented by a field sales force. OrCAD designs its marketing programs to reinforce 46 the recognition of its brand through integrated advertising, direct mail, electronic marketing, and other promotional activities. OrCAD's sales effort is designed to capture, qualify and respond effectively to the leads generated by the marketing programs. OrCAD also generates leads through customer and consultant references. To effectively target and measure all of these efforts, OrCAD has invested in an information system that tracks contacts with customers and prospects. OrCAD's distribution strategy is intended to address the mainstream electronic design market in a productive, cost-effective manner. OrCAD believes that its direct field sales force will allow it to better meet the unique buying requirements of management in large organizations. OrCAD intends to use its penetration at the individual and group level in large organizations to help achieve enterprise-wide standardization on its products. OrCAD maintains an ongoing program of market research based on industry reports, customer input, surveys, and frequent communication with value-added resellers (VARs). This research helps OrCAD to set priorities for product development, technical support, and other functional areas. Trade shows and OrCAD's training classes provide additional means of soliciting customer feedback. Direct Sales. OrCAD's direct sales effort consists primarily of a telesales force supplemented with a targeted field sales presence. Telesales are typically generated by inbound inquiries stimulated by OrCAD's marketing programs, additional sales to existing customers, and references from customers. OrCAD believes telesales has been a cost-effective means of distributing its products and gaining customer acceptance. OrCAD believes that its direct field sales force will allow it to better meet the unique requirements of selling directly to management at large organizations. Indirect Sales. OrCAD's VARs are a key component of OrCAD's sales and marketing strategy in international markets, outside of Japan. VARs provide local technical support, and in some instances local language documentation, and run a variety of direct marketing programs that build on materials developed for the North American direct marketing efforts. OrCAD derived approximately $8.2 million, $4.1 million and $3.9 million, or approximately 39%, 30% and 39% of its total revenue, from international sales in 1996, 1995 and 1994, respectively. Substantially all of OrCAD's international revenue to date has been derived from indirect sales made by its VARS and Japanese distributor. For distribution in Japan, OrCAD purchased its Japanese distributor in 1995 to increase its direct presence in that country. Beyond North America and Japan, OrCAD distributes its products through leading EDA VARs. Because OrCAD's products are used by professional engineers and other technical personnel, effective VARs must possess sufficient technical, marketing and sales resources and must devote these resources to sales efforts, customer education, training, consulting and support. Only a limited number of potential VARs possess these criteria. There can be no assurance that OrCAD will be able to attract and retain a sufficient number of qualified VARs to successfully market OrCAD's products, and the failure to do so would have a material adverse effect on OrCAD's business, financial condition and results of operations. OrCAD's relationship with its VARs is usually established through a formal reseller agreement, which generally may be terminated by either party at any time without cause. There can be no assurance that any VAR will continue to represent OrCAD's products, and the inability to retain VARs could have a material adverse effect on OrCAD's business, financial condition and results of operations. Strategic Relationships. OrCAD has strategic relationships with and works closely with other companies to develop and market their products and to provide customers with application-specific solutions. In addition, OrCAD has developed relationships with a number of FPGA and CPLD vendors such as Actel, Altera, Lattice Semiconductor, Lucent Technologies, Vantis, and Xilinx for the purpose of marketing integrated solutions to joint prospects and customers. SERVICE AND SUPPORT OrCAD believes that to compete in the desktop EDA marketplace, it must provide a unique variety of support services, including customer service, software implementation, technical support, training and consulting service referrals. 47 OrCAD offers product support agreements that include product updates, access to electronic bulletin board services, newsletters and technical support available by telephone, fax, electronic mail and through its World Wide Web page. OrCAD has created programs for both in-house and on-site training for all products. In North America, OrCAD has developed a strong technical support capability comprised primarily of electrical engineers who understand the customers' design processes and OrCAD's products. Internationally, OrCAD Japan and VARs provide support to OrCAD customers. In addition, OrCAD's technical support resources are available to support OrCAD Japan and VARs. PRODUCT DEVELOPMENT OrCAD's product development process is customer-centric, led by a product marketing group which researches customer requirements, and supported by research and development, test, and documentation teams which develop OrCAD's products. OrCAD's plans for future developments include productivity improvements for target applications; language-based design and synthesis; component-information systems development and support for advanced PCB routing technology. OrCAD has a MicroSoft Windows C++ development environment, in which it develops its products using Microsoft Foundation Class UI objects. As of December 31, 1996, there were 47 people in the above mentioned groups. In 1996, 1995 and 1994, OrCAD invested 21%, 26% and 30% of revenue, respectively, in research and development. All software development costs are expensed as incurred. The EDA industry is characterized by rapid technological change, frequent new product introductions, evolving industry standards, and changing customer requirements. The introduction of products embodying new technologies and the emergence of new industry standards can render existing products obsolete and un-marketable. OrCAD believes that it must continue to commit substantial resources to product development and, that its future success will depend on its continued ability to enhance its current products and to develop or acquire new products that keep pace with technological developments, emerging industry standards and changing customer requirements. There can be no assurance that OrCAD will be successful in developing and marketing any such new products or product enhancements, or that such new products and enhancements will adequately meet the requirements of the marketplace and achieve market acceptance. In the past, OrCAD has experienced delays in its introduction of product enhancements and new products. If OrCAD is unable, for technological or other reasons, to develop and introduce products in a timely manner in response to changing market conditions or customer requirements, OrCAD's business, financial condition and results of operations will be materially and adversely affected. COMPETITION The EDA industry is highly competitive. OrCAD currently competes in the desktop EDA market directly with Viewlogic, which offers Windows- and UNIX- based products. OrCAD also faces competition from large vendors of traditional UNIX-based EDA products. Some of these companies, such as Cadence, Synopsis, Mentor Graphics and others, have announced or shipped Windows-based products. OrCAD also competes with smaller, privately held companies. A number of OrCAD's competitors have significantly greater financial, technical and marketing resources than OrCAD, and strong name recognition. There can be no assurance that these competitors will not use their superior resources and visibility, and installed customer bases, to successfully develop better products and/or market their products more effectively than those of OrCAD. In particular, as a result of the wide acceptance of UNIX-based EDA tools, vendors of such tools have established long-term relationships with many of OrCAD's current and potential customers, and may have the ability to offer these customers a broad suite of Windows- and UNIX-based products to satisfy the entire range of their design needs. Finally, in addition to competition from EDA software vendors, OrCAD faces competition from the internal design groups of many of its customers, who design and develop customized electronic design automation tools for their own particular needs and therefore may be reluctant to purchase products offered by OrCAD or other independent EDA vendors. There can be no assurance that OrCAD will be able to convert such internal design groups into users of OrCAD's products. More generally, there can be no assurance that OrCAD will be able to compete successfully against current and future competitors, both direct and indirect, or that competitive pressures faced by OrCAD will not materially adversely affect its business, financial condition and results of operations. 48 PROPRIETARY RIGHTS OrCAD's success is heavily dependent upon its proprietary software technology. OrCAD currently relies on a combination of trade secret, copyright and trademark laws, and contractual provisions to protect its proprietary rights in its software products. OrCAD also ships its software with a security device to all customers outside the U.S. and Canada. OrCAD generally enters into proprietary information and confidentiality agreements with its employees and distributors, and limits access to and distribution of its software, documentation and other proprietary information. OrCAD does not license or release the source code for its proprietary software to its customers, except in connection with OEM development agreements. Despite these precautions, there can be no assurance that a third party will not copy or otherwise obtain and use OrCAD's products or technology without authorization, or develop similar or superior technology independently. In particular, OrCAD distributes its products pursuant to "shrink-wrap" licenses. There can be no assurance that such licenses are enforceable. In addition, effective copyright and trade secret protection may be unavailable or limited in certain foreign countries. Although OrCAD believes that its products do not infringe on the proprietary rights of third parties, and although OrCAD has received no communications from third parties alleging the infringement of the proprietary rights of such parties, there can be no assurance that infringement claims will not be asserted against OrCAD in the future and that any such claims will not require OrCAD to enter into costly litigation. Irrespective of the validity or the successful assertion of such claims, any such litigation could result in significant diversions of effort by OrCAD's technical and management personnel, as well as OrCAD's incurring significant costs with respect to the defense thereof, and could have a material adverse effect on OrCAD's business, financial condition and results of operations. In addition, if any claims or actions are asserted against OrCAD, OrCAD may choose to or be required to obtain a license under a third party's intellectual property rights. There can be no assurance that under such circumstances a license would be available upon reasonable terms or at all. EMPLOYEES As of December 31, 1996, OrCAD had 123 employees, including 61 in marketing and sales, 40 in research and development and 22 in general and administrative capacities. Of these, 111 were located at OrCAD's headquarters in Beaverton, Oregon, and 12 were located at OrCAD's subsidiary in Yokohama, Japan. None of OrCAD's employees is represented by a labor union or is subject to a collective bargaining agreement. OrCAD believes that its employee relations are good. OrCAD's future success depends in significant part upon the continued service of its key senior management, professional and technical personnel. OrCAD's future success also depends on its continuing ability to attract and retain highly qualified technical, professional and managerial personnel. Competition for such personnel is intense, and there can be no assurance that OrCAD can retain its key employees or that it can attract, assimilate or retain other highly qualified personnel in the future. PROPERTIES OrCAD occupies approximately 39,000 square feet of space at its headquarters in Beaverton, Oregon under a lease expiring in 2001, subject to OrCAD's right to extend. OrCAD's subsidiary in Japan leases approximately 3,000 square feet of space at its Yokohama, Japan office. OrCAD believes that its existing facilities, including expansion options, are adequate for its current needs and that suitable additional space will be available as needed. LEGAL PROCEEDINGS From time to time, OrCAD becomes involved in ordinary, routine or regulatory legal proceedings incidental to the business of OrCAD. OrCAD is not presently a party to any litigation, the outcome of which would have a material adverse effect on OrCAD's business, financial condition or results of operations. 49 SELECTED ORCAD CONSOLIDATED FINANCIAL DATA The following selected historical financial data of OrCAD have been derived from OrCAD's historical financial statements.

Words such as "expects," "anticipates," "intends," "plans," "believes," "seeks," "estimates" and variations of such words and similar expressions are intended to identify such forward-looking statements. OrCAD's actual results could differ materially from those discussed herein. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in "Quarterly Results of Operations" as well as those discussed in this section and elsewhere in this Joint Proxy Statement/Prospectus, and other risks detailed from time to time in OrCAD's Securities and Exchange Commission reports. The industry in which OrCAD competes and the markets that it serves are highly cyclical. OrCAD is dependent upon the semiconductor and, more generally, the computer and electronics industries. Each of these industries is characterized by rapid technological change, short product life cycles, fluctuations in manufacturing capacity and pricing and gross margin pressures. Segments of these industries, in each of the United States, Europe and Japan, have from time to time experienced significant economic downturns characterized by decreased product demand, reductions in capital expenditures, production over-capacity, price erosion, work slowdowns and layoffs. In addition, portions of these industries have experienced downturns at different times. Over the past few years, these industries have experienced an extended period of significant economic growth in North America, although in Europe and Japan the growth of such industries has been slower. There can be no assurance that such economic growth in North America will continue, and if it does not, any downturn could be severe. OrCAD's operations may in the future reflect substantial fluctuations from period to period as a consequence of such industry patterns, general economic conditions affecting the timing of orders from major customers, and other factors affecting capital spending. There can be no assurance that such factors will not have a material adverse effect upon OrCAD's business, financial condition and results of operations. OVERVIEW OrCAD was formed in September 1991 as the successor to prior entities engaged in developing electronic design automation tools. From its inception, OrCAD has been engaged in the development and marketing of a broad family of EDA products including schematic capture, digital simulation, programmable logic design and printed circuit board layout. From 1993 to 1994, OrCAD upgraded its entire DOS product family to the 386+ series, intended for optimal performance with PCs based on Intel 386 and 486 microprocessors. In 1995, OrCAD introduced OrCAD Design Desktop for Windows, a new product family designed for the 32-bit Windows operating system that included OrCAD Capture for Windows, OrCAD Simulate for Windows, OrCAD Layout for Windows, OrCAD Layout Ltd. for Windows and OrCAD Layout Plus for Windows. In 1997 OrCAD introduced OrCAD Express for Windows, OrCAD Express Enterprise Edition, OrCAD Capture Enterprise Edition, OrCAD Layout Engineers' Edition, and OrCAD Enterprise Bridge. From OrCAD's inception through the first six months of 1995, OrCAD earned substantially all of its revenue from its DOS-based EDA products. For the year ended December 31, 1996, and for the six months ended June 30, 1997, Windows-based products accounted for more than 90% of OrCAD's total revenue. In June 1995, OrCAD acquired Massteck Ltd., a developer of Windows-based PCB layout technology. This acquisition enabled OrCAD to introduce the OrCAD Layout for Windows product family in June 1995, simultaneously with the release of OrCAD Capture for Windows. In December 1995, OrCAD acquired Intelligent Systems Japan (ISJ), OrCAD's distributor in Japan since 1991. The entity is now known as OrCAD Japan, K.K., and operates as a wholly owned subsidiary of OrCAD. 51 RESULTS OF OPERATIONS The following table sets forth for the periods indicated selected items of OrCAD's statements of operations as a percentage of its total revenue: AS A PERCENTAGE OF TOTAL REVENUE YEAR ENDED SIX MONTHS DECEMBER 31, ENDED JUNE 30, ---------------- ----------------- 1996 1995 1994 1997 1996 ---- ---- ---- ------- ------- (UNAUDITED) Revenue: Products................................ 85% 78% 82% 84% 86% Service................................. 15 22 18 16 14 --- --- --- ------- ------- Total revenue......................... 100 100 100 100 100 --- --- --- ------- ------- Cost and expenses: Cost of revenue--products............... 8 11 17 11 8 Cost of revenue--service................ 3 4 4 3 3 Research and development................ 21 26 30 21 21 Marketing and sales..................... 34 36 36 37 34 General and administrative.............. 15 14 14 12 15 In-process research and development..... -- 7 -- 17 -- --- --- --- ------- ------- Total cost and expenses............... 81 98 101 101 81 --- --- --- ------- ------- Income (loss) from operations............. 19 2 (1) (1) 19 --- --- --- ------- ------- Other income: Interest income (expense), net.......... 6 -- (1) 6 4 Other, net.............................. -- -- 2 -- -- --- --- --- ------- ------- 6 -- 1 6 4 --- --- --- ------- ------- Income before income taxes................ 25 2 -- 5 23 Income taxes.............................. 5 -- -- 2 5 --- --- --- ------- ------- Net income................................ 20% 2% -- % 3% 18% === === === ======= ======= YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994 Revenue OrCAD derives revenue from the licensing of its software products and from the provision of maintenance and training services to customers. OrCAD recognizes revenue from software licenses after shipment of product and when no significant contractual obligations remain outstanding. Service revenue is derived primarily from product support agreements that provide customers access to product enhancements, technical support, bulletin board services and a subscription to the OrCAD Design Desktop Quarterly, a newsletter produced by OrCAD. Revenue from each product support agreement is deferred and recognized ratably over the term of the product support agreement. Revenue from customer training is recognized as services are performed. Total revenue increased 53% to $20.9 million in 1996 from $13.7 million in 1995. Total revenue increased 39% in 1995 from $9.8 million in 1994. These increases were due to growth in both product revenue and service revenue. As a percentage of total revenue, product revenue increased to 85% in 1996 from 78% in 1995 and 82% in 1994. Conversely, service revenue decreased as a percentage of total revenue to 15% in 1996 from 22% in 1995 and 18% in 1994. Product revenue increased 68% to $17.8 million in 1996 from $10.6 million in 1995. Product revenue increased 33% in 1995 from $8.0 million in 1994. The acquisition of OrCAD Japan accounted for approximately 52 $3.2 million of the $7.2 million increase in product revenue in 1996. The remaining increase in product revenue in 1996 was primarily attributable to growth in sales of OrCAD Design Desktop for Windows, particularly in the Layout and Simulate product lines. The increase in 1995 was primarily due to increased revenue from sales of the recently introduced OrCAD Design Desktop for Windows product family at generally higher average selling prices than for previous products, and the recognition of revenue previously deferred until the release of OrCAD Capture for Windows, partially offset by decreased revenue from sales of DOS-based products. In 1994, OrCAD began selling its "Capture upgrade," consisting of a product support agreement for SDT 386+ and the right to upgrade to OrCAD Capture for Windows at no further charge. No product revenue from the Capture upgrade was recognized in 1994, although a portion of the revenue was deferred until the release of OrCAD Capture for Windows. In addition, to the extent OrCAD sold upgrades to its Windows-based products rather than the new products themselves, product revenue in 1995 was less than it otherwise might have been because upgrades have significantly lower average selling prices than new products and a higher proportionate service revenue content. Service revenue increased 2% to $3.1 million in 1996 from $3.0 million in 1995. Service revenue increased 69% in 1995 from $1.8 million in 1994. The higher increase in product revenue in 1996 as compared to service revenue was primarily attributable to an increase in sales of Windows-based products, a higher proportion of which is recognized as product revenue. The increase in service revenue in 1995 as a percentage of total revenue was primarily attributable to a shift in product mix from new product sales to upgrade sales. This shift resulted in increased service revenue because a higher proportion of revenue from sales of upgrade products is generally allocated to and deferred as service revenue than for new product sales. Total North American revenue increased 34% to $12.7 million in 1996 from $9.5 million in 1995. Total revenue generated outside North America increased 98% to $8.2 million in 1996 from $4.1 million in 1995. Total North American revenue increased 60% to $9.5 million in 1995 from $6.0 million in 1994. Total revenue generated outside North America remained relatively constant from 1994 to 1995, at $3.9 million and $4.1 million, respectively. As a percentage of OrCAD's total revenue, revenue generated outside North America increased to 39% in 1996 from 30% in 1995 and decreased to 30% in 1995 from 39% in 1994. The increase in the proportion of revenue generated outside of North America was principally attributable to the acquisition of OrCAD Japan. In 1995 OrCAD's sales to OrCAD Japan, which was OrCAD's distributor until December 2, 1995, amounted to approximately 8% of total revenue. In 1996, sales by OrCAD Japan amounted to approximately 21% of total revenue. This increase in revenue attributable to OrCAD Japan as a percentage of total revenue was primarily the result of OrCAD recognizing the full selling price of products sold by OrCAD Japan, whereas in 1995, prior to the acquisition, OrCAD's products were sold to OrCAD Japan at prices reflecting a substantial discount from OrCAD Japan's selling prices. The greater proportion of North American revenue to total revenue in 1995 was attributable to the earlier releases of OrCAD's new Windows-based products in the North American market. In addition, OrCAD's North American customer base traditionally has adopted new products earlier than its international customer base. Cost of Revenue The cost of product revenue represents the costs associated with the licensing of OrCAD's products, such as expenses of reproducing product documentation, disks and packaging, hardware locks, shipping costs and royalties paid to external developers. The cost of product revenue increased 12% to $1.8 million in 1996 from $1.6 million in 1995. The cost of product revenue decreased 7% to $1.6 million in 1995 from $1.7 million in 1994. The increase in cost of product revenue in 1996 is primarily due to an increased level of product sales partially offset by lower royalty costs resulting from OrCAD's purchase of source code previously licensed from outside developers, and OrCAD's decision to develop Windows-based products internally rather than through outside developers, as well as to reduced expenditures for software documentation and packaging. As a percentage of product revenue, cost of product revenue decreased to 10% in 1996 from 15% in 1995 and from 21% in 1994. This decrease was primarily the result of higher average selling prices resulting from the sale of OrCAD Design Desktop for Windows, primarily in the PCB layout and simulation product lines. 53 The cost of service revenue includes the costs of providing software maintenance, such as technical support, software revision releases and updated user documentation, and the costs of providing training. The cost of service revenue increased 49% to $727,000 in 1996 from $488,000 in 1995. The cost of service revenue increased 26% to $488,000 in 1995 from 387,000 in 1994. Both increases reflected increased service obligations as a result of increased training, product, upgrade and product support agreement sales. As a percentage of service revenue, cost of service revenue increased to 24% in 1996 from 16% in 1995 and from 22% in 1994. This increase reflected the absorption of relatively fixed costs and costs of increased technical support personnel in 1995 and 1996 over a relatively constant service revenue base. Research and Development Research and development expenses include the costs of developing new products and enhancements to existing products. Software development costs are expensed as incurred, in that technological feasibility is generally not established until shortly before the release of a new product and no material development costs are incurred after establishment of technological feasibility. Research and development expenses increased 20% to $4.3 million in 1996 from $3.6 million in 1995. Research and development expenses increased 22% to $3.6 million in 1995 from $2.9 million in 1994. The increase in research and development expenses in 1996 was primarily attributable to increased headcount largely resulting from the acquisitions of OrCAD Japan and Massteck, partially offset by a reduction in costs for engineering consultants. The increase in research and development expenses in 1995 over the same period a year earlier was attributable to increased personnel costs, including costs associated with increased headcount and the engagement of engineering consultants. As a percentage of total revenue, research and development expenses decreased to 21% in 1996 from 26% in 1995 and from 30% in 1994. OrCAD expects research and development expenses to continue to increase in absolute terms. Marketing and Sales Marketing and sales expenses include salaries, commissions and related personnel costs, and other sales and promotional expenses. Marketing and sales expenses increased 43% to $7.1 million in 1996 from $4.9 million in 1995. Marketing and sales expenses increased 38% to $4.9 million in 1995 from $3.6 million in 1994. The growth in marketing and sales expenses in 1996 was primarily attributable to increased compensation expense related to the growth in the direct telesales organization and increased headcount for marketing personnel, the acquisitions of OrCAD Japan and Massteck, and greater marketing related activities. OrCAD incurred approximately $338,000 in additional expenses in 1996 related to the amortization of intangible assets acquired in connection with the acquisition of OrCAD Japan. In addition, OrCAD increased its sales and marketing headcount by four employees as a result of the acquisition of Massteck. The increase in sales and marketing expenses in 1995 was principally attributable to increased personnel costs, including costs associated with increased headcount and compensation expenses related to growth in the direct telesales organization and the establishment of a direct field sales force. As a percentage of total revenue, marketing and sales expenses decreased to 34% in 1996 from 36% in 1995 and 1994. OrCAD expects marketing and sales expenses to continue to increase in absolute terms. General and Administrative General and administrative expenses include the costs associated with OrCAD's executive office, human resources, finance, information systems and operations functions. General and administrative expenses increased 61% to $3.1 million in 1996 from $1.9 million in 1995. General and administrative expenses increased 40% to $1.9 million in 1995 from $1.4 million in 1994. The increase in general and administrative expenses in 1996 was attributable to the acquisition of OrCAD Japan, increased personnel costs, including costs associated with increased headcount to support the growth in operations and the additional costs associated with being a public company. The acquisition of OrCAD Japan resulted in approximately $493,000 of general and administrative expenses in 1996. The increase in general and administrative expenses in 1995 was attributable to expenses incurred as OrCAD built a more sophisticated information systems infrastructure. As a percentage of total 54 revenues, general and administrative expenses increased to 15% in 1996 from 14% in 1995 and 1994. OrCAD expects general and administrative expenses to continue to increase in absolute terms to support the growth in operations and the additional costs associated with being a public company. In-Process Research and Development In connection with OrCAD's acquisition of Massteck in 1995, OrCAD expensed approximately $971,000 of in-process research and development costs associated with certain Windows-based PCB layout technology which had not yet reached technological feasibility. Other Income, Net Other income, net consists of interest income, gains and losses on the disposal of property and equipment, sublease income, royalty income and foreign currency gains and losses. Interest income consists primarily of the earnings on available cash balances and marketable securities, which have generally been invested in short-term money market investments, treasury bills and corporate debt securities. Other income, net increased to $1.3 million in 1996 from $105,000 in 1995 and from $156,000 in 1994. The increase in other income, net in 1996 was almost entirely from higher interest income earned on increased cash and marketable securities balances generated from the initial public offering completed in March 1996. The decrease in other income, net from 1994 to 1995 was due primarily to the completion in 1994 of the payments associated with the VHDL modeling division divestiture. Income Taxes OrCAD's effective tax rate for 1996 was 20.0%, which differs from the combined federal and state statutory rate of approximately 38.5% primarily due to the use of net operating loss carryforwards, and the foreign tax rate differential applicable to earnings of OrCAD Japan. OrCAD incurred net losses through 1994 for tax purposes and consequently paid no income taxes through that year. Due to these losses, OrCAD had federal and state net operating loss carryforwards for tax purposes of approximately $1.5 million and $1.2 million as of December 31, 1996, respectively. These carryforwards expire from 2006 through 2009. Net operating loss carryforwards were used to offset taxes payable on 1995 net income. SIX MONTHS ENDED JUNE 30, 1997 AND 1996 Revenue Total revenue increased 26% from $10.2 million in the first half of 1996 to $12.9 million in the first half of 1997. The increased revenue was due to successful new products and a new distribution channel. In the first half of 1997, OrCAD introduced Capture Enterprise Edition, OrCAD Express, OrCAD Express Enterprise Edition and OrCAD Enterprise Bridge and acquired certain assets of TEAM Corporation and hired TEAM's field sales staff and support organization. The remaining increase in total revenue was due to overall growth in product and service revenue. As a percentage of total revenue, product revenue decreased from 86% in the first half of 1996 to 84% in the first half of 1997. Conversely, service revenue increased as a percentage of total revenue from 14% in the first half of 1996 to 16% in the first half of 1997. Product revenue increased 22% from $8.8 million in the first half of 1996 to $10.8 million in the first half of 1997. The increase in product revenue was primarily attributable to hiring of TEAM's field sales and support organization, and the introduction of OrCAD Capture Enterprise Edition, OrCAD Express, OrCAD Express Enterprise Edition and OrCAD Enterprise Bridge. Service revenue increased 49% from $1.4 million in the first half of 1996 to $2.1 million in the first half of 1997. The increase in service revenue from the first half of 1996 to the first half of 1997 was primarily attributable to increased sales of customer training, consulting services and product support agreements. 55 Total North American revenue increased 51% from $5.9 million in the first half of 1996 to $8.9 million in the first half of 1997. Total revenue generated outside of North America decreased 7% from $4.4 million in the first half of 1996 to $4.0 million in the first half of 1997. As a percentage of the Company's total revenue, North American revenue increased from 57% in the first half of 1996 to 69% in the first half of 1997. The increase in the proportion of revenue generated in North America was principally attributable to the formation and integration of a field sales organization in the North American sales territory and the introduction of four new products; OrCAD Capture Enterprise Edition, OrCAD Express, OrCAD Express Enterprise Edition and OrCAD Enterprise Bridge. The decrease in the proportion of revenue generated outside of North America was due in part to the typical slower initial adoption rate of new products in Europe and Asia. Cost of Revenue The cost of product revenue increased 66% from $842,000 in the first half of 1996 to $1.4 million in the first half of 1997. The increase was primarily attributable to an increased level of product sales, higher royalty costs associated with OrCAD Capture Enterprise Edition and OrCAD Express Enterprise Edition relative to other product lines, and certain commissions payable to North American value-added resellers. As a percentage of product revenue, cost of product revenue increased from 10% in the first half of 1996 to 13% in the first half of 1997. This increase was primarily the result of the associated royalty costs for OrCAD Capture Enterprise Edition and OrCAD Express Enterprise Edition and commissions payable to North American resellers. The cost of service revenue decreased 3% from $357,000 in the first half of 1996 to $346,000 in the first half of 1997. As a percentage of service revenue, the cost of service revenue decreased from 25% in the first half of 1996 to 17% in the first half of 1997. This decrease reflects the absorption of a relatively small decrease in cost of service revenue in the first half of 1997 as compared to the first half of 1996 over a higher service revenue base. Research and Development Research and development expenses increased 24% from $2.2 million in the first half of 1996 to $2.7 million in the first half of 1997. The increase in research and development expenses was attributable to increased personnel costs, including costs associated with increased headcount, recruiting, relocation and the engagement of contract engineers. As a percentage of total revenue, research and development expenses remained constant at 21% in the first half of 1996 and the first half of 1997. Marketing and Sales Marketing and sales expenses increased 38% from $3.5 million in the first half of 1996 to $4.8 million in the first half of 1997. The increase in marketing and sales expenses was due to the formation of a field sales organization and promotional expenses associated with the introduction of OrCAD Capture Enterprise Edition, OrCAD Express, OrCAD Express Enterprise Edition, and OrCAD Enterprise Bridge products in the first half of 1997. As a percentage of total revenue, marketing and sales expenses increased from 34% in the first half of 1996 to 37% in the first half of 1997. General and Administrative General and administrative expenses remained steady at $1.5 million for the first half of 1996 and the first half of 1997. As a percentage of total revenue, general and administrative expenses decreased from 15% in the first half of 1996 to 12% in the first half of 1997. This decrease reflects the absorption of a relatively small increase in general and administrative costs in the first half of 1997 as compared to the first half of 1996 over a higher revenue base. In-Process Research and Development In connection with OrCAD's acquisition of certain software technology of TEAM Corporation and Q Point Technology in the first half of 1997, OrCAD expensed approximately $2.2 million of in-process 56 research and development costs associated with certain technology which had not yet reached technological feasibility. There were no expensed in-process research and development costs in the first half of 1996. Other Income, Net Other income increased from $477,000 in the first half of 1996 to $758,000 in the first half of 1997. This improvement resulted primarily from higher interest income earned on increased cash and cash equivalents and short-term investment balances resulting from the proceeds of OrCAD's initial public offering completed in March 1996. Income Taxes The effective tax rate for the first half of 1997 was 35.0%, which differs from the combined federal and state statutory rate of approximately 38.5% because of the utilization of net operating loss carryforwards, the utilization of research and experimentation tax credits, and the benefit of OrCAD's foreign sales corporation. Income tax expense for the first half of 1997 was $244,000 as compared to a $494,000 expense for the first half of 1996. The decrease in income tax expense is primarily attributable to in- process research and development charges related to the acquisition of certain assets of TEAM Corporation and Q Point Technology. The increase in the estimated effective tax rate in the first half of 1997 as compared to the first half of 1996 is primarily due to the utilization of net operating loss carryforwards in 1996. QUARTERLY RESULTS OF OPERATIONS OrCAD's quarterly operating results have in the past varied and may in the future vary significantly depending on factors such as increased competition, timing of new product announcements, releases and pricing changes by OrCAD or its competitors, length of sales cycles, market acceptance or delays in the introduction of new or enhanced versions of OrCAD's products, timing of significant orders, seasonal factors, mix of direct and indirect sales, product mix, and economic conditions generally and in the EDA industry specifically. In particular, OrCAD's quarterly operating results have in the past fluctuated as a result of the timing of the introduction of new products to the market, with customers waiting to place orders until new products became available. OrCAD's quarterly operating results have also fluctuated as a result of seasonality of customer buying patterns. A substantial portion of OrCAD's revenue in each quarter results from orders booked in that quarter. Revenue from quarter to quarter is difficult to forecast, as minimal backlog exists at the end of any quarter because OrCAD's products typically are shipped and revenue recognized promptly after receipt of customers' orders. OrCAD's expense levels are based, in part, on its expectations as to future revenue. If revenue levels are below expectations, operating results are likely to be adversely affected. In particular, net income may be disproportionately affected by a reduction in revenue because only a small portion of OrCAD's expenses varies with its revenue. OrCAD has recently experienced rapid growth and expansion. There can be no assurance that OrCAD will be able to grow in future periods, that it will be able to sustain its historical rate of revenue growth, or that its operations will remain profitable. Due to the foregoing factors, OrCAD believes that period-to-period comparisons of its results of operations are not necessarily meaningful and should not be relied upon as indications of future performance. 57 SELECTED UNAUDITED QUARTERLY FINANCIAL DATA THREE-MONTH PERIOD ENDED ----------------------------------------------------------------------- 1996 1995 ---------------------------------- ----------------------------------- MARCH 31 JUNE 30 SEPT. 30 DEC. 31 MARCH 31 JUNE 30 SEPT. 30 DEC. 31 -------- ------- -------- ------- -------- ------- -------- ------- (IN THOUSANDS) Revenue: Products............... $4,248 $4,579 $4,537 $4,458 $2,076 $2,671 $2,714 $3,166 Service................ 677 730 786 892 641 728 780 883 ------ ------ ------ ------ ------ ------ ------ ------ Total revenue.......... 4,925 5,309 5,323 5,350 2,717 3,399 3,494 4,049 ------ ------ ------ ------ ------ ------ ------ ------ Cost and expenses: Cost of revenue-- products.............. 447 395 468 461 449 330 397 411 Cost of revenue-- service............... 165 192 171 199 89 111 135 153 Research and development........... 1,005 1,150 1,067 1,064 773 934 915 939 Marketing and sales.... 1,695 1,813 1,829 1,742 937 1,232 1,171 1,594 General and administrative........ 756 741 743 823 395 430 447 632 In-process research and development........... -- -- -- -- -- 971 -- -- ------ ------ ------ ------ ------ ------ ------ ------ Total cost and expenses.............. 4,068 4,291 4,278 4,289 2,643 4,008 3,065 3,729 ------ ------ ------ ------ ------ ------ ------ ------ Income (loss) from operations............. 857 1,018 1,045 1,061 74 (609) 429 320 Other income (expense), net.................... 110 367 411 384 (2) 10 44 53 ------ ------ ------ ------ ------ ------ ------ ------ Income (loss) before taxes.................. 967 1,385 1,456 1,445 72 (599) 473 373 Income tax expense...... 184 310 306 251 -- -- 1 3 ------ ------ ------ ------ ------ ------ ------ ------ Net income (loss)....... $ 783 $1,075 $1,150 $1,194 $ 72 $ (599) $ 472 $ 370 ====== ====== ====== ====== ====== ====== ====== ====== THREE-MONTH PERIOD ENDED ----------------------------------------------------------------------- 1996 1995 ---------------------------------- ----------------------------------- MARCH 31 JUNE 30 SEPT. 30 DEC. 31 MARCH 31 JUNE 30 SEPT. 30 DEC. 31 -------- ------- -------- ------- -------- ------- -------- ------- (IN THOUSANDS) As a Percentage of Total Revenue: Revenue: Products............... 86% 86% 85% 83% 76% 79% 78% 78% Service................ 14 14 15 17 24 21 22 22 ------ ------ ------ ------ ------ ------ ------ ------ Total revenue.......... 100 100 100 100 100 100 100 100 ------ ------ ------ ------ ------ ------ ------ ------ Cost and expenses: Cost of revenue-- products.............. 9 7 9 9 17 10 11 10 Cost of revenue-- service............... 3 4 3 4 3 3 4 4 Research and development........... 20 22 20 20 28 27 26 23 Marketing and sales.... 34 34 34 33 34 36 34 39 General and administrative........ 15 14 14 15 15 13 13 16 In-process research and development........... -- -- -- -- -- 29 -- -- ------ ------ ------ ------ ------ ------ ------ ------ Total cost and expenses.............. 81 81 80 81 97 118 88 92 ------ ------ ------ ------ ------ ------ ------ ------ Income (loss) from operations............. 19 19 20 19 3 (18) 12 8 Other income (expense), net.................... 2 7 8 7 -- -- 1 1 ------ ------ ------ ------ ------ ------ ------ ------ Income (loss) before taxes.................. 21 26 28 26 3 (18) 13 9 Income tax expense...... 4 6 6 5 -- -- -- -- ------ ------ ------ ------ ------ ------ ------ ------ Net income (loss)....... 17% 20% 22% 21% 3% (18%) 13% 9% ====== ====== ====== ====== ====== ====== ====== ====== OrCAD's total revenue increased each quarter in 1996. The decline in product revenue in the third and fourth quarters of 1996 was primarily due to a higher proportion of product support agreement sales, reflecting renewals of product support agreements and a general increase in OrCAD's installed base. Total revenue and product revenue increased each quarter in 1995. Total revenue and product revenue increased substantially in the second quarter of 1995, reflecting the release in June 1995 of the first two OrCAD Design Desktop for Windows products--OrCAD Capture for Windows and the OrCAD Layout for Windows product family. Revenue from these products resulted both from new sales during the quarter and from revenue previously deferred on sales of 58 the Capture Upgrade. Revenue also increased significantly in the first quarter of 1996 primarily due to the acquisition of OrCAD Japan in December 1995. Service revenue increased in each quarter in 1996 and 1995, with the exception of the decline in the first quarter of 1996. The decline in service revenue in the first quarter of 1996 was primarily due to an increase in sales of Windows-based products, a higher proportion of which are recognized as product revenue. The cost of revenue has varied on a quarterly basis as a result of a number of factors, including differing margins and royalties payable to third parties, costs associated with providing product updates under both product support agreements and initial product warranties, discounts allowed on sales to OrCAD's distributor in Japan in 1995 and commissions paid to VARs. The cost of revenue as a percentage of total revenue reflects a general downward trend in the cost of revenue through the second quarter of 1996. The cost of revenue as a percentage of total revenue in the first quarter of 1995 reflects the relatively higher sales of lower margin products and royalty payments to third parties. The subsequent decrease in the second quarter of 1995 reflects the elimination of royalties formerly paid to Massteck as a result of the Massteck acquisition and the discontinuation of a low margin OEM product family. Operating expenses have generally increased in absolute terms as OrCAD has increased expenditures and staffing in its research and development, sales and marketing, and general and administrative functions. In particular, personnel were added to research and development to accelerate the completion of the OrCAD Design Desktop for Windows product family, supplemented by consultants in various quarters. OrCAD also added personnel to marketing and sales to create and expand its direct telesales organization and more recently its direct field sales force for strategic accounts. In addition, the occurrence of major tradeshows and associated product release publicity expenditures caused marketing and sales expenses to increase substantially in the second quarter of 1996 and 1995. OrCAD incurred an increase in sales and marketing expenses due to certain promotional costs associated with the release of certain of OrCAD's Windows-based products in the fourth quarter of 1995. OrCAD's general and administrative expenses increased substantially in the fourth quarter of 1996 due to the incurrence of a bad debt charge related to a distributor in Japan. General and administrative expenses increased substantially in the fourth quarter of 1995 as a result of the consolidation of OrCAD Japan's operations with those of OrCAD. LIQUIDITY AND CAPITAL RESOURCES Total cash and cash equivalents were $22.6 million at June 30, 1997 as compared to $20.3 million at December 31, 1996. Cash provided by operations was $2.1 million for the first half of 1997 as compared to $2.2 million for the first half of 1996. The decrease in cash provided by operations for the first half of 1997 as compared to the first half of 1996 was primarily due to an increase in trade accounts receivable. Cash provided by investing activities was $42,000 for the first half of 1997 as compared to $8.3 million used in the first half of 1996. Purchases of investment securities with the proceeds of the initial public offering in March 1996 accounted for a substantial portion of cash used in investing activities in the first half of 1996. Cash provided by investing activities during the first half of 1997 was generated primarily from the sale of short-term securities. The completion of the initial public offering of common stock in March 1996 and the exercise of OrCAD's underwriters over-allotment option in April 1996 resulted in net proceeds of $23.3 million which improved OrCAD's current ratio to 7.9:1 at December 31, 1996 from 1.4:1 at December 31, 1995. Working capital improved to $29.6 million at December 31, 1996 from $1.6 million at December 31, 1995. OrCAD has available borrowing capacity consisting of a $3.0 million line of credit from a commercial bank. As of December 31, 1996, there was no indebtedness outstanding under this facility. OrCAD believes that current cash and investment balances, cash flows from operations and the unused line of credit are sufficient to meet current and anticipated future capital requirements for at least the next twelve months. OrCAD currently has no significant capital commitments other than commitments under facility operating leases. OrCAD has from time to time evaluated and continues to evaluate opportunities for acquisitions and expansion and, consistent with this practice, is currently engaged in preliminary discussions with other parties regarding possible acquisitions. Any 59 such transactions, if consummated, may use a portion of OrCAD's working capital or necessitate additional bank borrowings. No assurance can be given that additional borrowing capacity will be available or that, if available, such financing will be obtainable on terms favorable to OrCAD or its stockholders. Cash and cash equivalents increased $18.2 million from December 31, 1995 to December 31, 1996 and $1.5 million from December 31, 1994 to December 31, 1995. Net cash of $4.9 million, $1.6 million, and $1.3 million was provided by operations in 1996, 1995 and 1994, respectively. Net income accounted for a substantial portion of the change in cash from operations from 1995 to 1996, and net income, after consideration of the non-cash in-process research and development charge, accounted for a substantial portion of cash from operations in 1995. Purchases of investment securities with the proceeds of the initial public offering and acquisitions of fixed assets accounted for a substantial portion of the cash used in investing activities of $9.9 million in 1996. In 1995, cash provided by investing activities of $21,000 reflected cash acquired in the acquisitions of OrCAD Japan and Massteck, partially offset by the acquisition of fixed assets and intangibles. Acquisitions of fixed assets accounted for a substantial amount of the cash used in investing activities of $180,000 in 1994. Proceeds from the initial public offering accounted for nearly all of the $23.3 million of cash generated from financing activities in 1996. Cash used in financing activities in 1995 of $87,000 reflected payments on capital lease obligations, partially offset by the proceeds from the issuance of common stock. Borrowings and repayments under OrCAD's line of credit accounted for a substantial portion of the $825,000 used in financing activities in 1994. The functional currency of OrCAD's Japanese subsidiary, OrCAD Japan, is the Japanese yen which must be translated to U.S. dollars for consolidation. Generally, Japanese sales are denominated in the Japanese yen. From December 31, 1995 to December 31, 1996, the U.S. dollar strengthened by approximately 12% against the Japanese yen. This strengthening of the U.S. dollar resulted in lower reported revenues and operating expenses due to translation of the Japanese yen to U.S. dollars for consolidated financial reporting. As such, OrCAD's business and operating results will be impacted by the effects of future U.S. dollar and Japanese yen currency fluctuations. NEW ACCOUNTING PRONOUNCEMENTS In February 1997, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standard (SFAS) No. 128, "Earnings per Share." This Statement establishes a different method of computing net income per share than is currently required under the provisions of Accounting Principles Board Opinion No. 15. Under SFAS No. 128, OrCad will be required to present both basic net income per share and diluted net income per share. Basic net income per share is expected to be comparable or slightly higher than the currently presented net income per share as the effect of dilutive stock options will not be considered in computing basic net income per share. Diluted net income per share is expected to be comparable or slightly lower than the currently presented net income per share. OrCAD plans to adopt SFAS No. 128 in the fourth quarter of 1997 and at that time all historical net income per share data presented will be restated to conform to the provisions of this Statement. In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income." This Statement establishes standards for the reporting and display of comprehensive income and its components. OrCAD plans to adopt SFAS No. 130 on January 1, 1998. The impact on OrCAD's Financial Statements is not expected to be material. In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information." This Statement establishes standards for reporting operating segments in annual Financial Statements and requires selected information about operating segments in interim Financial Statements. OrCAD plans to adopt SFAS No. 131 on January 1, 1998. The impact on OrCAD's Financial Statements is not expected to be material. 60 BUSINESS OF MICROSIM OVERVIEW MicroSim develops, markets and supports Microsoft Windows-based and Unix- based electronic design automation ("EDA") software products that assist electronics designers in designing integrated circuits ("ICs") and printed circuit boards ("PCBs"), including circuits that include both analog and digital components ("mixed-signal" circuits). MicroSim is the desktop EDA industry's leading brand name and supplier for analog and mixed-signal simulation products. These products have accounted for over 90% of MicroSim's revenue since its inception. MicroSim products enable electronic circuit designers to reduce time to market, improve product capability and reduce design costs. MicroSim's EDA solutions support the design process for mainstream components, from schematic capture to verification to programmable logic design to printed circuit board layout. Over 30,000 products bearing the MicroSim name have been sold worldwide since 1984. PRODUCTS MicroSim's products address the process of designing analog and mixed-signal circuits from schematic capture to PCB layout. With MicroSim products, engineers can move back and forth, from the schematic to simulation to programmable logic synthesis to PCB layout, continuously improving circuit performance. Engineers can also browse the circuit and identify opportunities to optimize various facets of the design. MicroSim's principal products are designed for Windows. MicroSim Schematics is a graphical EDA front-end that speeds the process of designing an electronic system. Engineers using MicroSim Schematics can create a schematic, simulate it, and prepare it for printed circuit board layout, all with the same 32-bit Windows-standard user interface. Its "Design Journal" capability allows engineers to explore alternative solutions simultaneously, enabling them to create better designs faster. MicroSim Schematics includes (i) a schematic editor that is integrated with MicroSim's other products; (ii) a design manager that allows design engineers to browse their design workspace; (iii) a parts library, containing more than 40,000 parts, together with a part editor and wizard that allows designers to quickly modify existing parts or create new ones; and (iv) features to create reports and send design data to other tools, such as AutoCAD. MicroSim PSpice A/D is an analog/digital simulator that offers the design engineer close integration between analog and digital designs, and integrates both simulation and waveform analysis for mixed analog and digital systems. Many of today's electronic circuits combine both analog and digital components. MicroSim PSpice A/D accelerates the design of these circuits by providing simulation and analysis of the system before it is built. MicroSim PSpice A/D includes (i) MicroSim Schematics; (ii) a graphical waveform display and analysis program that allows engineers to view and calculate circuit performance; (iii) a library of over 10,000 models for analog and digital parts; and (iv) a graphical simulation model editor that allows engineers to modify models and create new ones. MicroSim PSpice is an analog only simulator that MicroSim first introduced in 1984, and has enhanced in numerous releases since. MicroSim PSpice's integration with MicroSim Schematics allows engineers to analyze and refine their designs in a single Windows-based graphical environment. The analysis capabilities (such as parametric analysis and Monte Carlo analysis) of MicroSim PSpice give engineers an understanding of circuit performance that enables them to create better designs. MicroSim PSpice includes (i) MicroSim Schematics; (ii) a graphical waveform display and analysis program that allows engineers to view and calculate circuit performance; (iii) a library containing more than 8,500 analog part models; and (iv) a graphical simulation model editor that allows engineers to modify models and create new ones.

It is integrated with MicroSim Schematics and MicroSim PSpice A/D, allowing engineers to do both circuit design and layout to improve overall circuit performance and time-to-market. MicroSim PCBoards includes the industry leading Cadence (formerly Cooper & Chyan Technology) SPECCTRA ShapeBased autorouter to provide fast routes and high completion rates. MicroSim PCBoards also includes a library of more than 1,400 footprints and an interactive footprint editor that enables designers to modify existing footprints or create new ones. MicroSim DesignLab enables engineers to design in an integrated manner. Within this integrated design environment engineers can move back and forth between creating the schematic diagram, simulating both analog and digital circuits, synthesizing both PLDs and CPLDs, designing and simulating systems containing Xilinx FPGAs, and laying out printed circuit boards. MicroSim DesignLab includes MicroSim Schematics, MicroSim PSpice A/D, and MicroSim PCBoards. It also includes additional features for PLD, CPLD and FPGA design. MARKETING AND SALES MicroSim markets and sells its products worldwide through marketing communications activities and a sales organization that is composed of a telesales force in the United States, and independent distributors in various countries. MicroSim's distribution strategy is intended to reach and support EDA engineers and designers using MicroSim's desktop software in a productive, efficient and cost-effective manner. Marketing. MicroSim develops and implements a number of marketing and marketing communications programs to create awareness and reinforce recognition of its brand and company name. MicroSim uses a mix of advertising, direct mail, electronic marketing, trade show participation and other activities to reach its customers. The various marketing programs and customer references generate leads that are gathered, documented and organized. In the United States, the telesales organization qualifies and responds to those leads. Leads relating to offshore customers are communicated to distributors in the respective geographic locations. In addition, MicroSim maintains regular contact with the industry's editorial community, and has provided contributing editorial articles in electronics industry publications. MicroSim maintains a program of market research based on surveys, industry reports and distributor communications, and actively seeks customer feedback. This information contributes to MicroSim's product development and customer support requirements. Domestic Sales. MicroSim products are sold domestically primarily through its telesales organization. Telesales are typically generated by inbound inquiries resulting from MicroSim's marketing programs, customer referrals and repeat inquiries from existing customers. Two independent distributors in the United States complement MicroSim's domestic telesales efforts. Foreign Sales. Outside the United States, MicroSim has over thirty independent distributors that sell MicroSim products within specified geographical areas. These distributors provide local technical support and often local language documentation. The distributors also develop and conduct marketing programs specific to their local markets. These local marketing programs are supported by MicroSim, built on the marketing communications materials developed by MicroSim for the domestic market, and tailored to local international use. In Japan, MicroSim is represented by both its wholly owned subsidiary, MicroSim Japan, K.K., and independent distributors. RESEARCH AND DEVELOPMENT MicroSim's product development process is customer-centric, led by a product management group that researches customer requirements, and supported by software development, quality assurance and documentation groups that develop MicroSim's products. MicroSim's plans for future development include productivity improvements for large designs, language-based design, design management, and integration of the overall design process. MicroSim has a Microsoft Windows C++ development environment, in which it develops its products using Microsoft Foundation Class UI objects. In fiscal 1996, 1995 and 1994, MicroSim invested 31%, 62 25%, and 30% of revenue, respectively, in research and development. All software development costs are expensed as incurred. COMPETITION The EDA industry is highly competitive. MicroSim competes primarily with small, privately held companies, including Intusoft and Deutsch Technology Research. MicroSim also faces competition from larger vendors of traditional UNIX-based EDA products. Some of these companies, such as Cadence, Synopsis, Viewlogic, Mentor Graphics and others, have either announced or shipped Windows-based products. A number of MicroSim's competitors have significantly greater financial, technical and marketing resources than MicroSim, and strong name recognition. There can be no assurance that these competitors will not use their superior resources and visibility, and installed customer bases, to successfully develop better products and/or market their products more effectively than those of MicroSim. In particular, as a result of the wide acceptance of UNIX-based EDA tools, vendors of such tools have established long-term relationships with many of MicroSim's current and potential customers, and may have the ability to offer these customers a broad suite of Windows- and UNIX-based products to satisfy the entire range of their design needs. Finally, in addition to competition from EDA software vendors, MicroSim faces competition from the internal design groups of many of its customers, who design and develop customized electronic design automation tools for their own particular needs and therefore may be reluctant to purchase products offered by MicroSim or other independent EDA vendors. There can be no assurance that MicroSim will be able to convert such internal design groups into users of their products. More generally, there can be no assurance that MicroSim will be able to compete successfully against current and future competitors, both direct and indirect, or that competitive pressures faced by MicroSim will not materially adversely affect its business, financial condition and results of operations. PROPRIETARY RIGHTS MicroSim's success is heavily dependent upon its proprietary software technology. MicroSim currently relies on a combination of trade secret, copyright and trademark laws, and contractual provisions to protect its proprietary rights in its software products. MicroSim also ships its software with a security device. MicroSim generally enters into proprietary information and confidentiality agreements with its employees and distributors, and limits access to and distribution of its software, documentation and other proprietary information. MicroSim does not license or release the source code for its proprietary software to its customers, except for a fraction of the PSpice simulator software, which is sold as a model development product. REVENUE MIX MicroSim derived approximately $8.1 million, $7.0 million, and $5.3 million, or approximately 50%, 48%, and 44%, of its total revenue from international sales in 1996, 1995 and 1994, respectively. Substantially all of MicroSim's international revenue to date has been derived from independent distributor sales and from its Japanese subsidiary. EMPLOYEES As of December 31, 1996, MicroSim had 97 employees, including 20 in marketing and sales, 51 in research and development, and 26 in general and administrative capacities. Of these, 93 were located at MicroSim's headquarters in Irvine, California, and 4 were located at MicroSim's subsidiary in Tokyo, Japan. None of MicroSim's employees is represented by a labor union or is subject to a collective bargaining agreement. MicroSim believes that its employee relations are good, and has not experienced any work stoppage from any labor dispute. PROPERTIES MicroSim occupies approximately 42,756 square feet of space at its headquarters in Irvine, California under a lease expiring in 2004, subject to MicroSim's right to extend. MicroSim's subsidiary in Japan leases 63 approximately 1,000 square feet at its Tokyo, Japan office. MicroSim believes that its existing facilities, including expansion options, are adequate for its current needs and that suitable additional space will be available as needed. LEGAL PROCEEDINGS In the ordinary course of business, MicroSim and/or one or more of its subsidiaries may become involved in legal proceedings from time to time. As of the date of mailing of this Joint Proxy Statement/Prospectus, neither MicroSim nor either of its subsidiaries is a party, and none of their property is subject, to any pending legal proceedings. 64 SELECTED MICROSIM FINANCIAL DATA The following selected historical financial data of MicroSim have been derived from MicroSim's historical financial statements.

Words such as "expects," "anticipates," "intends," "plans," "believes," "seeks," "estimates" and variations of such words and similar expressions are intended to identify such forward-looking statements. MicroSim's actual results could differ materially from those discussed herein. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in this section and elsewhere in this Joint Proxy Statement/Prospectus. The industry in which MicroSim competes and the markets that it serves are highly cyclical. MicroSim is dependent upon the semiconductor and, more generally, the computer and electronics industries. Each of these industries is characterized by rapid technological change, short product life cycles, fluctuations in manufacturing capacity and pricing and gross margin pressures. Segments of these industries, in each of the United States, Europe and the Pacific Rim, have from time to time experienced significant economic downturns characterized by decreased product demand, reductions in capital expenditures, production over-capacity, price erosion, work slowdowns and layoffs. In addition, portions of these industries have experienced downturns at different times. There can be no assurance that economic growth in applicable markets worldwide will continue, and if it does not, any downturn could be severe. MicroSim's operations may in the future reflect substantial fluctuations from period to period as a consequence of such industry patterns, general economic conditions affecting the timing of orders from major customers, and other factors affecting capital spending. There can be no assurance that such factors will not have a material adverse effect upon MicroSim's business, financial condition and results of operations. OVERVIEW MicroSim was founded in 1984 with the introduction of MicroSim PSpice, an analog circuit simulator developed for use on the PC. In 1987, MicroSim introduced mixed analog/digital simulation with MicroSim PSpice A/D. In 1991, MicroSim introduced versions of its products running under the MicroSoft Windows standard user interface. Currently, over 90% of MicroSim's revenues are derived from sales and support of its Windows-based products. MicroSim PCBoards was introduced in 1995 followed by MicroSim DesignLab in 1996. SEE "BUSINESS OF MICROSIM--Products". 66 RESULTS OF OPERATIONS The following table sets forth for the periods indicated selected items of MicroSim's statements of income as a percentage of its total revenue: AS A PERCENTAGE OF TOTAL REVENUE SIX MONTHS YEAR ENDED DECEMBER 31, ENDED JUNE 30, --------------------------- ----------------- 1996 1995 1994 1997 1996 ------- ------- ------- ------- ------- (UNAUDITED) Revenue: Products........................ 83% 85% 85% 78% 84% Service......................... 17 15 15 22 16 ------- ------- ------- ------- ------- Total revenue................. 100 100 100 100 100 ------- ------- ------- ------- ------- Costs and expenses: Cost of revenue--products....... 15 14 16 12 14 Cost of revenue--service........ 5 4 5 6 5 Research and development........ 31 25 30 36 31 Marketing and sales............. 29 27 27 31 27 General and administrative...... 11 11 11 10 12 Write-off of purchased software....................... -- 7 -- -- -- ------- ------- ------- ------- ------- Total costs and expenses...... 91 88 89 95 89 ------- ------- ------- ------- ------- Income from operations............ 9 12 11 5 11 ------- ------- ------- ------- ------- Other income: Interest income................. 2 2 1 2 2 Interest expense................ -- -- (1) -- -- ------- ------- ------- ------- ------- 2 2 -- 2 2 ------- ------- ------- ------- ------- Income before income taxes........ 11 14 11 7 13 Income taxes...................... 4 5 2 2 4 ------- ------- ------- ------- ------- Net income........................ 7% 9% 9% 5% 9% ======= ======= ======= ======= ======= YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994 Revenue MicroSim derives revenue from the licensing of its software products and from the provision of maintenance. MicroSim recognizes revenue from sales of software licenses upon shipment of software to the customer. Service revenue is derived primarily from product support agreements that provide customers access to product enhancements, and secondarily from an allocation of a portion of each product's sale price to service revenue to cover technical support MicroSim provides to its customers. Revenue from each product support agreement is deferred and recognized ratably over the term of the product support agreement, typically twelve months. Total revenue increased 10% to $16.1 million in 1996 from $14.7 million in 1995. Total revenue increased 21% in 1995 from $12.1 million in 1994. These increases were due to growth in both product and service revenue. As a percentage of total revenue, service revenue increased to 17% in 1996 from 15% in 1995 and 1994, reflecting renewals of product support agreements from a larger installed base and sales of new product support agreements. Product revenue increased 7% to $13.3 million in 1996 from $12.5 million in 1995. Product revenue increased 21% in 1995 from $10.3 million in 1994. The increase in product revenue in 1996 and 1995 was 67 primarily attributable to increased sales of MicroSim's analog and mixed analog/digital simulation products (the PSpice Products). Product mix was reasonably consistent across all three years, with revenues from the PSpice Products accounting for 93% to 95% of total product revenue during that time. Slower growth in 1996 than 1995 reflects slower markets both domestically and internationally in 1996. Service revenue increased 30% to $2.8 million in 1996 from $2.1 million in 1995. Service revenue increased 20% in 1995 from $1.8 million in 1994. The increases in service revenue are attributable to the continued renewals of product support agreements from a growing installed user base and the sale of product support agreements with new product licenses. MicroSim serves three principal markets geographically: the United States; Pacific Rim; and Europe. Sales to these three markets accounted for 50%, 25% and 21%, respectively, in 1996; 52%, 20% and 24%, respectively, in 1995 and 56%, 17%, and 23%, respectively, in 1994 of MicroSim's total revenue. The most significant revenue growth over the period came from the Pacific Rim, where MicroSim established a branch sales office in Japan in 1994. This branch office was incorporated as MicroSim Japan, K.K. in 1996. Revenues from the Pacific Rim increased 43% to $4.1 million in 1996 from $2.9 million in 1995. Revenues from the Pacific Rim increased 36% in 1995 from $2.1 million in 1994. Cost of Revenue Cost of revenue--products represents the costs associated with the sale of licenses to MicroSim's products, including the costs of developing and reproducing product documentation, production of CDs and packaging, security devices, shipping costs and royalties paid to others for third party technology incorporated in MicroSim's products. Cost of revenue--products increased 14% to $2.4 million in 1996 from $2.1 million in 1995, and increased 10% in 1995 from $1.9 million in 1994. The increases in cost of revenue-- products in 1996 and 1995 primarily resulted from increased expenses in the development and production of product documentation. In the third quarter of 1995 MicroSim added to its Technical Publications staff to improve the quality and usability of its product documentation. The cost of revenue--products also increased as a function of increased revenues. Cost of revenue--products remained consistent as a percentage of product revenue at 18%, 17% and 18% for 1996, 1995 and 1994, respectively. Cost of revenue--service represents the costs of providing software maintenance, including technical support and software updates. MicroSim typically updates its products twice each year. Cost of revenue--service increased 25% to $776,000 in 1996 from $621,000 in 1995, and 6% in 1995 from $586,000 in 1994. The increases reflect the increased costs associated with greater service obligations, and additions to the number of service personnel at the end of 1995 and early in 1996. MicroSim increased its technical support staff in the fourth quarter of 1995 due to the introduction of MicroSim PCBoards during that quarter. As a percentage of service revenue, cost of revenue--service decreased to 28% in 1996 from 29% in 1995 and 33% in 1994. These improvements result from the relatively fixed nature of costs associated with product service agreement revenue. Research and Development Research and development expenses include the costs of developing new products and enhancing existing products. Software development costs are expensed as incurred, in that technological feasibility is generally not established until shortly before the release of a new product and no material development costs are incurred after the establishment of technological feasibility. Research and development expenses increased 37% to $5.1 million in 1996 from $3.7 million in each of 1995 and 1994. The increase in 1996 was primarily due to a 50% growth in the number of research and development personnel from 1995 to the end of 1996. MicroSim added staff to support an expanding product offering as well as to institute a new product development process that placed a greater emphasis on testing throughout the development cycle. The number of employees in research and development remained relatively constant from 1994 to 1995. 68 Marketing and Sales Marketing and sales expenses increased 24% to $4.8 million in 1996 from $3.9 million in 1995 and 18% in 1995 from $3.3 million in 1994. As a percentage of total revenue, marketing and sales expenses were 29%, 27% and 27% in 1996, 1995 and 1994, respectively. The increase in 1996 in both absolute and percentage terms was primarily attributable to increased marketing expenses associated with two new product introductions. These expenses included the cost of developing and placing advertisements and the cost of developing and printing collateral material related to MicroSim DesignLab, introduced in October 1996, and MicroSim PCBoards, introduced in December 1995. General and Administrative General and administrative expenses increased 8% to $1.7 million in 1996 from $1.6 million in 1995. General and administrative expenses increased 17% in 1995 from $1.4 million in 1994. The increases in 1996 and 1995 were due to increased personnel costs and higher general and administrative expenses associated with MicroSim Japan's growth. Write-off of Purchased Software In 1995, MicroSim wrote off its investment in purchased printed circuit board autorouting software when it ceased using it, following licensing and adoption of an alternate supplier's product. Interest Income Interest income increased in 1996 and 1995 primarily due to increased cash, cash equivalents and short-term investments. The increased interest earning balances resulted from cash generated from operations. Income Taxes MicroSim's effective tax rates for 1996, 1995 and 1994 were 38%, 34% and 20%, respectively. The increase in the effective tax rate in 1996 was due to losses from MicroSim Japan that did not yield any corresponding tax benefit. The 20% effective tax rate in 1994 resulted from the research and experimentation tax credit being effective for the entire year (as opposed to half years in 1995 and 1996) and lower pretax earnings compared to 1996 and 1995. SIX MONTHS ENDED JUNE 30, 1997 AND 1996 Revenue Total revenue increased 2% to $7.9 million in the first half of 1997 from $7.7 million in the first half of 1996. Product revenue decreased 5% to $6.1 million in the first half of 1997 from $6.5 million in the corresponding period in 1996. Product revenue from MicroSim's Windows-based products, which comprised over 94% of total product revenues in the first half of 1997, remained relatively constant during the two periods. The decrease in MicroSim's product revenue was due primarily to decreased revenue from its UNIX- and DOS-based products. MicroSim discontinued selling its DOS-based products in 1996. Service revenue increased 39% to $1.8 million in the first half of 1997 from $1.3 million in the first half of 1996. The increase in service revenue is attributable to renewals of product support agreements from a larger installed base, as well as the sale of product support agreements with new product licenses. As a percentage of total revenue, revenue from the United States, Pacific Rim and Europe accounted for 53%, 23% and 21%, respectively, in the first half of 1997 compared to 49%, 28% and 19%, respectively, in the first half of 1996. The changes in the geographic mix result primarily from a decline in revenue of approximately 17% from the Pacific Rim in the first half of 1997 compared to the first half of 1996. 69 Cost of Revenue Cost of revenue--products decreased 9% to $1.0 million in the first half of 1997 from $1.1 million in the first half of 1996. The decrease was primarily attributable to the decrease in product revenue between the periods, and reduced shipping costs. As a percentage of product revenue, cost of revenue-- products decreased to 16% in the first half of 1997 from 17% in the first half of 1996. Cost of revenue--service increased 28% to $447,000 in the first half of 1997 from the corresponding period in 1996. The increase reflects the increased costs associated with greater service commitments. As a percentage of service revenue, cost of revenue--service decreased to 25% in the first half of 1997 from 27% in the corresponding period of 1996. Research and Development Research and development expenses increased 16% to $2.8 million in the first half of 1997 from $2.4 million in the first half of 1996. The increased expenses were primarily due to staffing growth to support an expanding product offering as well as to institute a new product development process that placed a greater emphasis on testing throughout the development cycle. Much of the increase in staffing occurred in the second half of 1996 and the first quarter of 1997. Marketing and Sales Marketing and sales expenses increased 16% to $2.4 million in the first half of 1997 from $2.1 million in the first half of 1996. The increase was due to staff growth in the second half of 1996 related to an expanded product offering. This staff growth is also reflected in a percentage increase in sales and marketing expenses as a percentage of total revenue to 31% in the first half of 1997 from 27% in the first half of 1996. General and Administrative General and administrative expenses decreased 16% to $775,000 in the first half of 1997 from $918,000 in the corresponding period of 1996. As a percentage of total revenue, general and administrative expenses decreased to 10% in the first half of 1997 from 12% in the corresponding period in 1996. The decrease in general and administrative expenses was primarily due to reduced personnel costs resulting from a reduction in staffing levels. Interest Income Interest income decreased slightly in the first half of 1997 compared to the first half of 1996 due to slightly lower interest rates during 1997. Income Taxes MicroSim's effective tax rates for the first half of 1997 and 1996 were 38% and 36%, respectively. The increase in the effective tax rate in 1997 was due to losses from MicroSim Japan without any corresponding tax benefit. QUARTERLY RESULTS OF OPERATIONS MicroSim's quarterly operating results have in the past varied and may in the future vary significantly depending on factors such as increased competition, timing of new product announcements, releases and pricing changes by MicroSim or its competitors, length of sales cycles, market acceptance or delays in the introduction of new or enhanced versions of MicroSim's products, timing of significant orders, seasonal factors, mix of direct and indirect sales, product mix, and economic conditions generally and in the EDA industry specifically. In particular, MicroSim's quarterly operating results have in the past fluctuated as a result of the timing of the introduction of new products to the market, with customers waiting to place orders until new products became 70 available. MicroSim's quarterly operating results have also fluctuated as a result of seasonality of customer buying patterns. Revenue from quarter to quarter is difficult to forecast, as minimal backlog exists at the end of any quarter because MicroSim's products typically are shipped, and revenue therefore recognized, promptly after receipt of customers' orders. MicroSim's expense levels are based, in part, on its expectations as to future revenue. If revenue levels are below expectations, operating results are likely to be adversely affected. In particular, net income may be disproportionately affected by a reduction in revenue because only a small portion of MicroSim's expenses varies with its revenue. MicroSim has experienced both flat periods and periods of rapid growth and expansion. There can be no assurance that MicroSim will be able to grow in future periods, that it will be able to sustain its historical rate of revenue growth, or that its operations will remain profitable. Due to the foregoing factors, MicroSim believes that period-to-period comparisons of its results of operations are not necessarily meaningful and should not be relied upon as indications of future performance. 71 SELECTED UNAUDITED QUARTERLY FINANCIAL DATA THREE-MONTH PERIOD ENDED ----------------------------------------------------------------------- 1996 1995 ---------------------------------- ----------------------------------- MARCH 31 JUNE 30 SEPT. 30 DEC. 31 MARCH 31 JUNE 30 SEPT. 30 DEC. 31 -------- ------- -------- ------- -------- ------- -------- ------- (IN THOUSANDS) Revenue: Products............... $3,318 $3,150 $3,336 $3,543 $3,182 $2,826 $3,015 $3,492 Service................ 607 661 727 785 492 530 539 582 ------ ------ ------ ------ ------ ------ ------ ------ Total revenue........... 3,925 3,811 4,063 4,328 3,674 3,356 3,554 4,074 ------ ------ ------ ------ ------ ------ ------ ------ Costs and expenses: Cost of revenue-- products.............. 525 565 585 696 489 410 584 605 Cost of revenue-- service............... 161 186 188 241 142 141 162 176 Research and development........... 1,172 1,249 1,282 1,361 896 797 920 1,075 Marketing and sales.... 979 1,107 1,235 1,477 977 1,028 889 965 General and administrative........ 471 448 459 352 378 350 428 447 Write-off of purchased software.............. -- -- -- -- -- 1,037 -- -- ------ ------ ------ ------ ------ ------ ------ ------ Total costs and expenses.............. 3,308 3,555 3,749 4,127 2,882 3,763 2,983 3,268 ------ ------ ------ ------ ------ ------ ------ ------ Income (loss) from operations............. 617 256 314 201 792 (407) 571 806 Interest income......... 96 86 85 89 63 69 73 86 Interest expense........

The fluctuations in cash and cash equivalents primarily resulted from net changes in short-term investments. Net cash of $1.5 million, $3.7 million and $2.1 million was provided by operations in 1996, 1995, and 1994, respectively. Investing activities have primarily consisted of net changes in short-term investments. Financing activities have not been material. MicroSim does not anticipate future capital expenditures to exceed historical levels, typically less than $1.0 million annually. 72 MicroSim has been able to fund its working capital requirements principally with internally generated funds. MicroSim believes this source of funds and its cash and cash equivalents balance at June 30, 1997 will be sufficient to fund its requirements for working capital for the foreseeable future. NEW ACCOUNTING PRONOUNCEMENTS In February 1997, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standard (SFAS) No. 128, "Earnings per Share." This Statement establishes a different method of computing net income per share than is currently required under the provisions of Accounting Principles Board Opinion No. 15. Under SFAS No. 128, MicroSim will be required to present both basic net income per share and diluted net income per share. Basic net income per share is expected to be comparable or slightly higher than the currently presented net income per share as the effect of dilutive stock options will not be considered in computing basic net income per share. Diluted net income per share is expected to be comparable or slightly lower than the currently presented net income per share. MicroSim plans to adopt SFAS No. 128 in the fourth quarter of 1997 and at that time all historical net income per share data presented will be restated to conform to the provisions of this Statement. In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income." This Statement establishes standards for the reporting and display of comprehensive income and its components. MicroSim plans to adopt SFAS No. 130 on January 1, 1998. The impact on MicroSim's Financial Statements is not expected to be material. In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information." This Statement establishes standards for reporting operating segments in annual Financial Statements and requires selected information about operating segments in interim Financial Statements. MicroSim plans to adopt SFAS No. 131 on January 1, 1998. The impact on MicroSim's Financial Statements is not expected to be material. 73 ORCAD DIRECTORS AND EXECUTIVE OFFICERS The following table sets forth certain information with respect to the directors and executive officers of OrCAD.

The rights, preferences and privileges of holders of OrCAD Common Stock are subject to any series of Preferred Stock which OrCAD may issue in the future as described below. PREFERRED STOCK OrCAD's Board of Directors has the authority to issue Preferred Stock in one or more series and to fix the number of shares constituting any such series, the voting powers, designations, preferences and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof, including the dividend rights, dividend rate, terms of redemption, redemption price or prices, conversion and voting rights and liquidation preferences of the shares constituting any series, without any further vote or action by the stockholders of OrCAD. The issuance of Preferred Stock by the OrCAD Board could adversely affect the rights of holders of OrCAD Common Stock. For example, issuance of Preferred Stock could result in a series of securities outstanding that would have preference over the OrCAD Common Stock with respect to dividends and in liquidation and that could (upon conversion or otherwise) enjoy all of the rights appurtenant to the OrCAD Common Stock. The authority possessed by OrCAD's Board of Directors to issue Preferred Stock could potentially be used to discourage attempts by others to obtain control of OrCAD through merger, tender offer, proxy or consent solicitation or otherwise by making such attempts more difficult to achieve or more costly. The OrCAD Board may issue Preferred Stock without stockholder approval and with voting rights that could adversely affect the voting power of holders of OrCAD Common Stock. There are no agreements or understandings for the issuance of Preferred Stock, and the OrCAD Board has no present intention of issuing any shares of Preferred Stock. DELAWARE BUSINESS COMBINATION STATUTE; CERTAIN PROVISIONS OF RESTATED CERTIFICATE OF INCORPORATION AND RESTATED BYLAWS. OrCAD is subject to Delaware's Business Combination Act (Delaware GCL Section 203) (the "Business Combination Act"). The Business Combination Act generally prohibits a Delaware corporation from engaging in a "business combination" with an "interested stockholder," for a period of three years following the date such person became an "interested stockholder." With certain exceptions, an "interested stockholder" is a person or entity who or which owns 15% or more of the corporation's outstanding voting stock, including any rights to acquire such stock pursuant to an option, warrant, agreement, arrangement or understanding, or upon the exercise of conversion or exchange rights, or is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within the previous three years. 84 Business combination transactions for this purpose include (a) a merger or plan of share exchange with or caused by the "interested stockholder," (b) any sale, lease, mortgage or other disposition of the assets of the corporation or any subsidiary to or with the "interested stockholder" (except proportionately with the corporation's other stockholders) where the assets have an aggregate market value equal to 10% or more of the aggregate market value of the corporation's assets or outstanding capital stock, (c) certain transactions which result in the issuance of capital stock of the corporation or any subsidiary to the "interested stockholder," (d) certain transactions which result in an increase in the "interested stockholder's" proportionate ownership of any class or series of the corporation's or any subsidiary's stock, and (e) any receipt by the "interested stockholder" of any loan, advance, or other financial benefit provided by or through the corporation or any subsidiary. The three year moratorium on business combinations does not apply if (i) the "interested stockholder," as a result of the transaction in which such person became an "interested stockholder," owns at least 85% of the outstanding voting stock of the corporation (disregarding shares owned by directors who are also officers, and certain employee benefit plans), (ii) prior to the date on which a stockholder became an "interested stockholder," the OrCAD Board approved either the business combination or the transaction which resulted in the stockholder becoming an "interested stockholder," or (iii) the OrCAD Board and the holders of at least two-thirds of the outstanding voting stock of the corporation (disregarding shares owned by the "interested stockholder") approve the transaction, at an annual or special meeting of stockholders, after the "interested stockholder" acquires 15% or more of the corporation's voting stock. The Business Combination Act will have the effect of encouraging any potential acquiror to negotiate with OrCAD's Board of Directors and will also discourage certain potential acquirors unwilling to comply with its provisions. OrCAD's Restated Certificate of Incorporation and Restated Bylaws contain provisions which (i) if the number of directors is fixed at six or more, classify the OrCAD Board into three classes as nearly equal in numbers as possible, each of which, after a transitional period, will serve for three years with one class being elected each year, (ii) provide that directors may be removed by stockholders only for cause and only upon the vote of 67% of the votes then entitled to be cast for the election of directors, (iii) permit the OrCAD Board to issue up to 2,000,000 shares of Preferred Stock in one or more series and to fix the number of shares, and the voting powers and all other rights and preferences of any such series, without any further vote or action by OrCAD's stockholders, and (iv) provide that special meetings of OrCAD's stockholders may only be called by the OrCAD Board. The Preferred Stock could be issued with voting, liquidation, dividend and other rights superior to the rights of the Common Stock. All of the above described provisions may have the effect of lengthening the time required for a person to acquire control of OrCAD through a proxy contest or the election of a majority of the OrCAD Board and may deter any potential unfriendly offers or other efforts to obtain control of OrCAD. This could deprive OrCAD's stockholders of opportunities to realize a premium for their OrCAD Common Stock and could make removal of incumbent directors more difficult. At the same time, these provisions may have the effect of inducing any persons seeking control of OrCAD to negotiate terms acceptable to the OrCAD Board. Since these provisions make the removal of directors more difficult, they increase the likelihood that incumbent directors will retain their positions and, since the OrCAD Board has the power to retain and discharge management, could perpetuate incumbent management. TRANSFER AGENT The transfer agent and registrar for OrCAD Common Stock is ChaseMellon Shareholder Services, LLC. 85 COMPARATIVE RIGHTS OF MICROSIM SHAREHOLDERS AND ORCAD STOCKHOLDERS If the Merger is consummated, holders of MicroSim Stock and holders of options to acquire shares of MicroSim Stock will become holders of OrCAD Common Stock and the rights of the former MicroSim shareholders and option holders will be governed by the General Corporation Law and by the Restated Certificate of Incorporation of OrCAD (the "OrCAD Certificate") and the Restated Bylaws of OrCAD (the "OrCAD Bylaws"). The rights of OrCAD stockholders under the General Corporation Law and the OrCAD Certificate and the OrCAD Bylaws differ in certain respects from the rights of MicroSim shareholders under the Corporations Code and the Articles of Incorporation of MicroSim and the Bylaws of MicroSim. Certain differences between the rights of OrCAD stockholders and MicroSim shareholders are summarized below. This summary is qualified in its entirety by reference to the full text of such documents. For information as to how such documents may be obtained, see "AVAILABLE INFORMATION." CLASSES OF STOCK The General Corporation Law authorizes a corporation to have one or more classes of stock. The OrCAD Certificate authorizes common stock and preferred stock. See "DESCRIPTION OF OrCAD CAPITAL STOCK." The Corporations Code also authorizes a corporation to have one or more classes of stock. All rights of shares of a class must have voting, conversion and redemption rights, and other rights, preferences, privileges and restrictions identical to those of other shares of the same class, unless the class is divided into series. MicroSim's Articles of Incorporation provide for one class: MicroSim Common Stock. The following is a description of the preferences, limitations and relative rights of the OrCAD Common Stock and the MicroSim Common Stock. Dividends. Dividends on MicroSim Common Stock may be declared as, if and when declared by the Board. Dividends on OrCAD Common Stock may be declared as, if and when declared by the Board. Voting Rights. Each share of MicroSim Common Stock is entitled to one vote per share, except that votes may be cumulated in the election of the MicroSim Board. Each share of OrCAD Common Stock is entitled to one vote per share, and no cumulative voting rights exist. Redemption Provisions. MicroSim Common Stock is not subject to any redemption provisions. OrCAD Common Stock is not subject to any redemption provisions. AMENDMENTS TO ARTICLES OF INCORPORATION AND BYLAWS The Corporations Code authorizes a corporation's Board of Directors to adopt certain amendments to the corporation's Articles of Incorporation without shareholder action, including, without limitation, deleting the names and addresses of the initial directors or the initial agent, and effecting a stock split (unless the corporation has more than one class of shares outstanding). The Board of Directors may propose other amendments to the shareholders. Unless the Corporations Code or the corporation's Articles of Incorporation require a greater proportion, the amendment must generally be approved by the holders of a majority of the outstanding shares. Amendments that would make shares assessable, however, or authorize a remedy by judicial action for collecting an assessment on fully paid shares, must be approved by all outstanding shares. Furthermore, certain amendments to the Articles of Incorporation that particularly affect one class of shares, such as amendments that change the rights, preferences, privileges or restrictions of that class, must be approved by the holders of a majority of the outstanding shares of that class. Notwithstanding the foregoing, provisions in the Articles of Incorporation that require approval of a larger proportion or all of the shares may be amended or repealed only by such greater vote, unless the Articles of Incorporation provide otherwise. The Corporations Code generally authorizes either a corporation's Board of Directors or its shareholders (by majority vote) to amend, repeal or adopt new Bylaws. The Bylaws, Articles of Incorporation or the 86 Corporations Code may require shareholder approval, however, and all amendments that: (i) change a fixed number of directors; (ii) change the maximum or minimum number of directors; or (iii) change a fixed number of directors to a variable number of directors, or vice versa, must be approved by a majority of the outstanding shares. Furthermore, an amendment reducing the fixed number of the minimum number of directors to a number less than five cannot be adopted if more than 16 2/3% of the outstanding voting shares are voted against such amendment. The General Corporation Law authorizes a corporation's Board of Directors to adopt amendments to the corporation's Certificate of Incorporation and requires that all such amendments be submitted for stockholder action. Unless the General Corporation Law or the corporation's Certificate of Incorporation requires a greater proportion, the amendment must be approved by holders of a majority of the shares entitled to vote thereon, as well as by holders of a majority of the shares of any class entitled to vote thereon as a class. The OrCAD Certificate requires a vote of the holders of not less than 67% of the votes entitled to be cast for the election of directors in order to amend any provision of Article VIII of the OrCAD Certificate. Article VIII sets the number of directors, provides for the classification of directors, and prescribes a means for the removal of directors. The General Corporation Law authorizes a corporation's Certificate of Incorporation to confer on the corporation's Board of Directors the power to amend, repeal or adopt new Bylaws, and, unless such power is conferred on the Board of Directors in the Certificate of Incorporation, it also remains in the corporation's stockholders. The OrCAD Bylaws grant the Board of Directors the power to adopt, amend or repeal Bylaws, but do not limit OrCAD's stockholders' right to adopt, amend or repeal Bylaws. SHAREHOLDER POWER TO CALL SPECIAL SHAREHOLDERS' MEETING The Corporations Code provides that a special meeting of shareholders may be called by a corporation's Board of Directors, the Chairman of the Board, the President, the holders of at least ten percent (10%) of all the votes entitled to be cast on any issue proposed to be considered at the proposed special meeting, or such other persons as are authorized under the corporation's Articles of Incorporation or Bylaws. The Bylaws of MicroSim authorize the President, the Board of Directors or the Chairman of the Board of Directors (if the Board designates one) to call a special meeting of shareholders. The General Corporation Law provides that a special meeting of stockholders may be called by a corporation's Board of Directors, or such other persons as are authorized under the corporation's Certificate of Incorporation or Bylaws. The OrCAD Bylaws authorize the Board of Directors to call a special meeting of stockholders. APPROVAL OF CERTAIN CORPORATE TRANSACTIONS Under the Corporations Code, a merger agreement must generally be approved by the corporation's Board of Directors and the principal terms must be approved by the holders of both a majority of outstanding shares entitled to vote thereon and by the holders of a majority of the shares of each class of the corporation, unless the Corporations Code otherwise requires a greater proportion or the corporation's Articles of Incorporation require a greater proportion. MicroSim has only one class of stock outstanding. The Corporations Code provides that, in general, a corporation may sell, lease, exchange or otherwise dispose of all, or substantially all, of its property or assets outside of its ordinary course of business, if the Board of Directors and holders of a majority of the outstanding voting shares approve the principal terms of the transaction, unless a greater proportion is otherwise specified in the Corporations Code or the corporation's Articles of Incorporation. Under the General Corporation Law, an agreement of merger must be approved by the Board of Directors and by a majority of the outstanding shares entitled to vote thereon, unless the General Corporation Law, the corporation's Certificate of Incorporation or the Board of Directors requires a greater proportion. The OrCAD Certificate specifies that if OrCAD's stockholders are required by law to approve a merger, then at least 67% of 87 OrCAD's outstanding shares must approve the merger for it to be approved by the stockholders. The General Corporation Law also provides that a merger need not be authorized by the stockholders of the surviving corporation if (i) the agreement of merger does not amend the Certificate of Incorporation, (ii) each share of stock of the surviving corporation before the merger is to be an identical outstanding share of stock of the surviving corporation after the merger, and (iii) generally, the number of voting shares outstanding immediately after the merger, plus the voting shares issuable as a result of the merger, will not exceed by more than 20% the total number of voting shares of the surviving corporation outstanding immediately prior to the merger. The General Corporation Law provides that, in general, a corporation may at any meeting of its Board of Directors sell, lease or exchange all, or substantially all, of its property and assets, when and as authorized by a resolution adopted by the holders of a majority of the outstanding shares entitled to vote thereon. The OrCAD Certificate states that OrCAD may not sell, lease or exchange all, or substantially all of its property or assets unless the holders of at least 67% of OrCAD's outstanding shares entitled to vote thereon, vote for such a transaction. DISSENTERS' RIGHTS Under the Corporations Code, a shareholder is entitled to dissent from certain corporate actions and obtain payment of the fair market value of his or her shares, provided the shareholder complies with certain procedures. The actions which trigger a shareholder's dissenter rights include reorganizations where shareholder approval is required, such as certain mergers, share exchanges, sales of all or substantially all of the corporation's assets in exchange for the acquiror's securities, and share exchange tender offers. Under the General Corporation Law, a stockholder is entitled to an appraisal of his or her shares by the court of chancery and to obtain payment of the fair market value of his shares in the event of certain corporate actions. The actions which trigger a stockholder's appraisal rights include certain mergers and consolidations and, if required by a corporation's Certificate of Incorporation, exchanges, sales of all or substantially all of the corporation's assets, and amendments to the corporation's Certificate of Incorporation. Under the General Corporation Law, appraisal rights are not available to stockholders of a corporation if the shares of such corporation are listed on a national securities exchange or are designated as a national market system security. Because OrCAD's shares are quoted on the Nasdaq National Market, OrCAD stockholders are not entitled to appraisal rights. ANTI-TAKEOVER PROVISIONS The Corporations Code does not contain any "anti-takeover" provisions. The Corporations Code does, however, permit corporations to adopt certain provisions in their Articles of Incorporation that might discourage unfriendly takeover bids--for example, requiring the approval of a supermajority of the Board of Directors and/or the shareholders for certain transactions. The General Corporation Law contains a statute commonly known as the "Business Combination Act," which provides that in the event a person or entity acquires 15% or more of the voting shares of a Delaware corporation (an "Interested Stockholder"), the corporation and the Interested Stockholder, or any affiliated entity, may not engage in certain business combination transactions for a period of three (3) years following the date the person became an Interested Stockholder. Business combination transactions include, among other things, (i) merger or consolidation with, disposition of assets to or with, or issuance or redemption of stock to or from, the acquiring person, or (ii) the acquiring person's receipt of any disproportionate benefit as a stockholder. These restrictions do not apply if (i) the Interested Stockholder, as a result of the transaction in which such person became an Interested Stockholder, owns at least 85% of the outstanding voting shares of the corporation (disregarding shares owned by directors who are also officers, and certain employee benefit plans), (ii) the Board of Directors approves the share acquisition or business combination before the Interested Stockholder acquired 15% or more of the corporation's voting shares, or (iii) the Board of Directors and the holders of a least two-thirds of the outstanding voting shares of the corporation (disregarding shares owned by the Interested 88 Stockholder) approve the transaction after the Interested Stockholder acquires 15% or more of the corporation's voting shares. Both OrCAD and MicroSim believe that the Business Combination Act will have the effect of encouraging any potential acquiror to negotiate with OrCAD's Board of Directors and will also discourage certain potential acquirors unwilling to comply with its requirements. "BLANK CHECK" PREFERRED STOCK MicroSim's Articles of Incorporation do not contain "Blank Check" Preferred Stock authority. The OrCAD Certificate permits the Board of Directors to fix and determine the rights and preferences of Preferred Stock or special stock, commonly referred to as "Blank Check" Preferred Stock. The issuance of preferred stock with extraordinary rights may be used to deter hostile takeover attempts. REMOVAL OF DIRECTORS Under the Corporations Code, shareholders may remove one or more directors of a corporation without cause subject to certain restrictions and requirements in the Corporations Code. In addition, the superior court of the proper county may, at the suit of shareholders holding at least ten percent (10%) of the number of outstanding shares of any class, remove from office any director for fraud, dishonesty or gross abuse of authority or discretion with respect to the corporation and may bar such removed director from re-election for a prescribed period. Generally, under the General Corporation Law, stockholders may remove one or more directors of a corporation with or without cause. Unless the corporation's Certificate of Incorporation provides otherwise, a board member on a "classified board" may be removed only for cause. In cases where a corporation has cumulative voting or classes of directors, if less than the entire Board of Directors is removed, no director may be removed without cause unless the votes for removal would be insufficient to elect the director to the Board of Directors. The OrCAD Certificate provides that directors may be removed only for cause by the holders of at least 67% of the votes then entitled to be cast for the election of directors and only at a meeting of the stockholders called expressly for that purpose. CLASSIFIED BOARD OF DIRECTORS The Corporations Code permits a listed corporation (that is, a corporation whose shares are listed on the New York Stock Exchange or American Stock Exchange, or on NASDAQ if the corporation has at least 800 shareholders) to establish in the corporation's Articles of Incorporation or Bylaws, a Board of Directors under which directors can be divided into as many as three (3) classes to serve for terms of as many as three (3) years. A listed corporation may also amend its Articles of Incorporation or Bylaws to eliminate cumulative voting. An unlisted corporation may amend its Articles of Incorporation or Bylaws to provide for a classified Board of Directors and/or to eliminate cumulative voting when it becomes a listed corporation. The MicroSim Articles of Incorporation do not provide for classes of directors. The General Corporation Law permits a corporation to establish in the corporation's Certificate of Incorporation or Bylaws a classified board under which directors can be divided into as many as three (3) classes having staggered terms of office, with one (1) class of directors elected each year. The OrCAD Certificate and the OrCAD Bylaws provide that if the Board of Directors is composed of six (6) or more directors, it is to be a classified Board of Directors with three (3) classes of directors and staggered terms. SIZE OF BOARD OF DIRECTORS Both the Corporations Code and the General Corporation Law provide that the size of a corporation's Board of Directors may be specified in, or fixed in accordance with, the corporation's Bylaws. The General Corporation Law also states that the number of directors may also be specified in the corporation's Certificate of Incorporation, and if so specified, the number may only be changed by an amendment to the Certificate of 89 Incorporation. The Bylaws of MicroSim provide that the number of directors shall be five (5). The OrCAD Certificate and the OrCAD Bylaws provide that the number of directors shall be between three (3) and nine (9) and may be set by the vote of the Board of Directors. The size of the OrCAD Board is currently set at five (5). DIVIDENDS AND REPURCHASE OF SHARES The Corporations Code prohibits a corporation from making a distribution to its shareholders, unless the amount of the proposed distribution is less than or equal to the corporation's retained earnings immediately prior thereto or unless, after giving effect to such distribution, (i) the current assets of the corporation would be at least equal to its current liabilities, and (ii) the sum of the corporation's assets would be equal to at least one and one- quarter times its liabilities. In addition, a corporation may not make any distribution (including a redemption of its own shares) if the corporation is, or after the distribution would be, likely to be unable to pay its debts as they mature. The General Corporation Law permits a corporation, unless otherwise restricted by the corporation's Certificate of Incorporation, to make a distribution to its stockholders either (i) out of its surplus (total assets minus total liabilities minus capital) or (ii) in case there is no surplus, out of its net profits for the fiscal year during which the distribution is paid or the preceding fiscal year. In addition, the General Corporation Law permits a corporation to acquire its own shares. CLASS VOTING The Corporations Code provides that the holders of outstanding shares of a class are entitled to vote as a separate voting group with respect to amendments to the corporation's Articles of Incorporation that would affect such class in certain ways, including, without limitation: changing the aggregate number of authorized shares of such class, except for certain specified increases; effecting an exchange, reclassification or cancellation of all or part of the shares of such class, other than a stock split; effecting an exchange or creating a right of exchange of all or part of the shares of another class into the shares of such class; changing the rights, preferences, privileges or restrictions of the shares of such class; or creating a new class of shares having rights, preferences or privileges prior to the shares of such class. The General Corporation Law provides that the holders of outstanding shares of a class are entitled to vote as a separate voting group with respect to amendments to the corporation's Certificate of Incorporation that would affect such class in certain ways, including without limitation: changing the aggregate number of authorized shares of such class; changing the par value of the shares of such class; or, adversely altering the powers, preferences, or special rights of the shares of such class. LEGAL OPINION The legality of the OrCAD Common Stock to be issued in connection with the Merger is being passed upon for OrCAD by Ater Wynne Hewitt Dodson & Skerritt, LLP, Portland, Oregon. DATE FOR SUBMISSION OF STOCKHOLDER PROPOSALS Any stockholder proposal intended for inclusion in the proxy statement and form of proxy relating to OrCAD's 1998 annual meeting of stockholders must be received by OrCAD not later than December 30, 1997, pursuant to the proxy soliciting regulations of the Commission. In addition, OrCAD's Bylaws require that notice of stockholder proposals and nominations for director be delivered to the Secretary of OrCAD not less than 60 days nor more than 90 days prior to the date of an annual meeting, unless notice or public disclosure of the date of the meeting occurs less than 60 days prior to the date of such meeting, in which event, stockholders may deliver such notice not later than the 10th day following the day on which notice of the date of the meeting was mailed or public disclosure thereof was made. Nothing in this paragraph shall be deemed to require OrCAD to include in its proxy statement and form of proxy for such meeting any stockholder proposal which does not meet the requirements of the Commission in effect at the time. 90 EXPERTS The consolidated financial statements and consolidated financial statement schedule of OrCAD and its subsidiaries as of December 31, 1996 and 1995 and for each of the years in the three-year period ended December 31, 1996, included in this Joint Proxy Statement/Prospectus have been so included in reliance upon the report of KPMG Peat Marwick LLP, independent certified public accountants, and given on the authority of said firm as experts in auditing and accounting.

F-23 Notes to Consolidated Financial Statements.............................. F-24 F-1 INDEPENDENT AUDITORS' REPORT The Board of Directors and Stockholders OrCAD, Inc.: We have audited the accompanying consolidated balance sheets of OrCAD, Inc. and subsidiaries as of December 31, 1996 and 1995, and the related consolidated statements of operations, stockholders' equity, and cash flows for each of the years in the three year period ended December 31, 1996. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of OrCAD, Inc. and subsidiaries as of December 31, 1996 and 1995, and the results of their operations, and their cash flows for each of the years in the three year period ended December 31, 1996 in conformity with generally accepted accounting principles.

F-6 ORCAD, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (INFORMATION RELATING TO THE SIX-MONTH PERIODS ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED) (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA) (1) NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business OrCAD, Inc. ("OrCAD," or the "Company") develops, markets and supports software products that assist electronics designers in developing field- programmable gate arrays, including complex programmable logic devices, and printed circuit boards. The Company operates primarily in one business segment, comprising the electronic design automation industry. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, OrCAD Europe S.A.R.L. (OrCAD Europe), Massteck Ltd. (Massteck) and Intelligent Systems Japan, K.K. (ISJ) from the date of inception or acquisition. All intercompany balances have been eliminated in consolidation. In December 1995, the Company acquired ISJ in a transaction accounted for as a purchase. In June 1995, the Company acquired Massteck in a transaction accounted for as a purchase. In June 1994, the Company discontinued all operations of its wholly-owned subsidiary, OrCAD Europe. Cash and Cash Equivalents For purposes of the accompanying consolidated statements of cash flows, the Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash equivalents are stated at cost and consist primarily of money market funds, commercial paper, municipal bonds and municipal auction preferred stock. The carrying amount of cash and cash equivalents approximates fair value. Short-Term Investments Short-term investments, which consist of short-term debt securities and U.S. Treasury Notes, are reported at fair value, and are classified as available- for-sale securities. The cost of securities sold is determined using the specific identification method when computing realized gains and losses. Fair value is determined using available market information. Inventory Inventory consists primarily of packaging materials, diskettes, compact disks, hardware locks, and printed documentation. Inventory is carried at the lower of cost or market determined on a first-in, first-out basis. Fixed Assets Fixed asset acquisitions are recorded at cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, generally three to seven years. Amortization of leasehold improvements and assets under capital leases is calculated using the straight-line method over the shorter of the related lease term or economic life of the leased asset. Concentration of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents, short-term investments and accounts receivable. Management believes the credit risk associated with cash, cash equivalents and short-term investments is minimal. The Company sells its products to customers who are primarily designers and manufacturers of electronic components. The Company's F-7 ORCAD, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) (INFORMATION RELATING TO THE SIX-MONTH PERIODS ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED) (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA) accounts receivable are derived primarily from customers located in North America, Europe and Japan. Management believes that the risk of credit loss is reduced due to the diversity of its customers and their dispersion across many geographic areas and electronic industries. Revenue Recognition Revenue primarily includes revenue from software product shipments and revenue from product support agreements. The Company recognizes revenue from software licenses after shipment of product and when no significant contractual obligations remain outstanding. When the Company receives payment prior to shipment or fulfillment of a significant obligation to the customer, such payments are recorded as deferred revenue and recognized as revenue upon shipment or fulfillment of such obligation. A portion of revenue from product sales is deferred and recognized ratably over the maintenance period, generally three months. Deferred revenue on product support agreements that are sold separately from product sales is recognized ratably over the contract period, generally one year. Revenue from customer training, support and other services is recognized as the services are performed. Software Development Costs Under Statement of Financial Accounting Standards No. 86, software development costs are to be capitalized beginning when a product's technological feasibility has been established and ending when a product is made available for general release to customers. To date, the establishment of technological feasibility of the Company's products has occurred shortly before general release, and accordingly no costs have been capitalized. Purchased Software Technology The Company has acquired technologies in connection with certain business combinations and licensing agreements. The cost of such purchased technology is generally amortized using the straight-line method over its estimated useful life. Amortization expense for the years ended December 31, 1996, 1995 and 1994 was $92, $77 and $98 respectively. Foreign Currency The local currencies of the Company's foreign subsidiaries are the functional currencies. Assets and liabilities of the Company's foreign operation are translated into U.S. dollars using exchange rates in effect at the translation date, and revenue and expenses are translated into U.S. dollars using average exchange rates. The effects of foreign currency translation adjustments are included as a component of stockholders' equity. Gains or losses occurring on transactions, which have been insignificant, are included in the consolidated statements of operations as other income (expense). Foreign currency gains (losses) for the years ended December 31, 1996, 1995 and 1994 were $(18), $11, and $(17), respectively. Goodwill and Intangible Assets Intangible assets of $2,685 and $300, resulting from the acquisition of ISJ, are being amortized on a straight line basis over a ten year life and three year life, respectively, commencing in December 1995. Goodwill of $250, resulting from the acquisition of Massteck, is being amortized on a straight- line basis over a three year life commencing in June 1995. Goodwill and intangible asset amortization was $452, $79, and $0 for the years ended December 31, 1996, 1995 and 1994, respectively. F-8 ORCAD, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) (INFORMATION RELATING TO THE SIX-MONTH PERIODS ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED) (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA) Income Taxes Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases and operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Net Income Per Share Net income per share is computed using the weighted average number of common and common equivalent shares outstanding. Common equivalent shares from stock options, warrants, and preferred stock are excluded from the calculation where their effect is antidilutive, except that, pursuant to Securities and Exchange Commission Staff Accounting Bulletins, common and common equivalent shares issued at prices below the public offering price during the twelve months immediately preceding the initial filing date have been included in the calculation as if they were outstanding for all periods presented (using the treasury stock method). Fair Value of Financial Instruments The carrying amounts of cash and cash equivalents, accounts receivable, and accounts payable approximate fair value due to the short-term nature of these instruments. The fair value of short-term investments is based on current market values. Fair value estimates are made at a specific point in time, based on relevant market information about the financial instrument when available. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. New Accounting Pronouncements On January 1, 1996, the Company adopted the Financial Accounting Standards Board's Statement of Financial Accounting Standards (SFAS) No. 123 "Accounting for Stock-Based Compensation". This statement permits a company to choose either a new fair value based method of accounting for its stock-based compensation arrangements or to comply with the current APB Opinion 25 intrinsic value based method adding pro forma disclosures of net income and earnings per share computed as if the fair value based method had been applied in the financial statements. The Company has adopted SFAS No. 123 by retaining the APB Opinion 25 method of accounting for stock-based compensation with annual pro forma disclosures of net income and earnings per share. Use of Estimates Generally accepted accounting principles require management to make estimates and assumptions that affect the reported amount of assets, liabilities and contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. (2) ACQUISITIONS In December 1995, the Company issued 426,468 shares of common stock in exchange for all of the outstanding common stock of ISJ. The acquisition has been accounted for as a purchase, and the financial results of ISJ have been included in the accompanying consolidated financial statements since the date of acquisition. F-9 ORCAD, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) (INFORMATION RELATING TO THE SIX-MONTH PERIODS ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED) (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA) The cost of the acquisition has been allocated on the basis of the estimated fair value of the assets acquired and the liabilities assumed. Intangible assets of $2,685 and $300 represent the estimated fair value of the customer list and assembled workforce acquired from ISJ. The fair values of assets and liabilities acquired are presented below: Cash.................................. $ 422 Accounts receivable, net.............. 474 Inventory, net........................ 174 Deferred tax asset.................... 146 Prepaid and other..................... 6 Fixed assets.......................... 166 Other assets.......................... 52 Intangible assets..................... 2,985 Accounts payable......................

(43) ------ Net assets acquired................. $2,986 ====== In June 1995, the Company issued 510,031 shares of common stock and reserved 50,717 common shares for issuance upon exercise of vested common stock options in exchange for all of the outstanding common and preferred stock and vested stock options of Massteck. The acquisition has been accounted for as a purchase, and the financial results of Massteck have been included in the accompanying consolidated financial statements since the date of acquisition. The cost of the acquisition has been allocated on the basis of the estimated fair value of the assets acquired and liabilities assumed. This allocation resulted in an in-process research and development charge of $971, because certain acquired technology had not reached technological feasibility. The excess of the aggregate purchase price over the fair value of net assets acquired of approximately $250 was recognized as goodwill and is being amortized on a straight-line basis over three years. The fair values of assets and liabilities acquired are presented below: Cash.................................. $ 81 Accounts receivable, net.............. 170 Royalties receivable.................. 780 Inventory, net........................ 14 Prepaids and other.................... 12 Property and equipment................ 103 Goodwill.............................. 250 In-process research and development... 971 Accounts payable......................

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) (INFORMATION RELATING TO THE SIX-MONTH PERIODS ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED) (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA) In April 1997, the Company acquired certain technology and sales personnel from TEAM Corporation for approximately $1,900. The cost of the acquisition was allocated on the basis of the fair value of the assets acquired. This allocation resulted in a charge for in-process research and development of $1,800, and workforce capitalization of $126 at the purchase date. The charge for in-process research and development resulted from allocating a portion of the acquisition cost to TEAM's in-process product development that had not reached technological feasibility. In addition, there are certain contingent amounts payable over the next three years based on the achievement of specific revenue milestones. In June 1997, the Company acquired certain technology and development personnel from Q Point Technology for approximately $720. The cost of the acquisition was allocated on the basis of the fair value of the assets acquired. This allocation resulted in a charge for in-process research and development of $433, purchased technology capitalization of $248, and workforce capitalization of $39 at the purchase date. The charge for in- process research and development resulted from allocating a portion of the purchase price to Q Point's in-process product development that had not reached technological feasibility. The Company is amortizing the capitalized workforce and purchased technology over a period of three years and five years, respectively.

In addition, the portion of the valuation allowance for deferred tax assets for which subsequently recognized tax benefits was applied directly to contributed capital was $223 at December 31, 1996. This amount was attributable to differences between financial and tax reporting for employee stock option exercises. As of December 31, 1996, the Company has federal and state net operating loss carryforwards for tax purposes of approximately $1,461 and $1,187, respectively, which expire in 2006 through 2009. In addition, the Company has unused research and experimentation credits of $397, which expire in 2006 through 2011. Such credits can be offset against future federal income taxes after use of the loss carryforwards. F-14 ORCAD, INC.

The Company applies APB No. 25 and related Interpretations in accounting for its plan. Accordingly, no compensation cost has been recognized for its fixed stock option plans and its stock purchase plan. For SFAS No. 123 purposes, the fair value of each option grant has been estimated as of the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions for grants and purchase rights in 1996 and 1995, respectively: dividend yield of 0% for both years; expected volatility of 49% and 0%; risk-free interest rate ranged from of 5.3% to 6.4% in 1996 and from 5.3% to 6.7% in 1995 for all plans; and expected lives of five years and five years for all Plans except the 1995 Stock Option Plan and the 1996 Employee Stock Purchase Plan options, 2 years and 2 years for the 1995 Stock Option Plan and .5 years and .5 years for the 1996 Employee Stock Purchase Plan.

F-18 REPORT OF INDEPENDENT AUDITORS The Board of Directors MicroSim Corporation: We have audited the accompanying consolidated balance sheets of MicroSim Corporation as of December 31, 1996 and 1995, and the related consolidated statements of income, shareholders' equity and cash flows for each of the three years in the period ended December 31, 1996. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of MicroSim Corporation at December 31, 1996 and 1995, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 1996, in conformity with generally accepted accounting principles.

F-23 MICROSIM CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BUSINESS AND BASIS OF PRESENTATION MicroSim Corporation (the Company) was incorporated in California in June 1984 and engages principally in the development and marketing of software applications which aid in the design and engineering of electrical circuits. The accompanying financial statements consolidate the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. Certain reclassifications have been made to prior year amounts to conform to the 1996 presentation. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of the Company, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the six month period ended June 30, 1997 are not necessarily indicative of the results that may be expected for the year ending December 31, 1997. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results could differ from those estimates. SHORT-TERM INVESTMENTS Investments purchased with maturities of more than three months and less than twelve months are classified as short-term investments which are available-for-sale. Short-term investments consist primarily of U.S. government obligations and commercial paper. At December 31, 1995, there was no material unrealized gain or loss on available-for-sale short-term investments. STOCK SPLIT On April 30, 1996, the Company declared a stock dividend of four shares of common stock for each share held, which has been reflected as a stock split. All share and per share data has been restated to reflect the stock split. INVENTORIES Inventories are valued at the lower of cost, determined on the first-in, first-out method, or market. The inventories consist primarily of sales materials and supplies for packaging software systems. PROPERTY AND EQUIPMENT Property and equipment, at cost, consists of the following (in thousands): DECEMBER 31, JUNE 30, ------------- 1997 1996 1995 ----------- ------ ------ (UNAUDITED) Computer equipment................................ $2,194 $2,010 $2,431 Furniture and fixtures............................ 437 420 393 Trade show equipment.............................. 130 130 130 Leasehold improvements............................ 134 46 46 ------ ------ ------ 2,895 2,606 3,000 Less accumulated depreciation and amortization.... 2,044 1,878 2,238 ------ ------ ------ $ 851 $ 728 $ 762 ====== ====== ====== F-24 MICROSIM CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) Depreciation of furniture and equipment is provided using the straight-line method over estimated useful lives of three to five years. Amortization of leasehold improvements is provided using the straight-line method over the shorter of the lease term or the estimated useful life. LONG-LIVED ASSETS The Company adopted the provisions of Statement of Financial Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of, (SFAS 121) on January 1, 1996. The adoption of SFAS 121 did not have a material impact on the Company's financial position or results of operations. REVENUE RECOGNITION AND SIGNIFICANT CUSTOMER The Company recognizes revenue from sales of software licenses upon shipment of the software to the customer. Technical support revenue, included with the initial license fee, is deferred and recognized over the estimated service period. Sales to one customer represented 12% of total revenue for each of the years ended December 31, 1996, 1995 and 1994. MAINTENANCE CONTRACTS The Company offers maintenance contracts to its customers to provide enhanced versions (updates) of its software products. Revenues related to these contracts are deferred and recognized on a straight-line basis over the one year life of the contract. RESEARCH AND DEVELOPMENT Research and development expenses incurred in the design, development and testing of new software until technological feasibility has been established for the product and software maintenance and enhancement costs, are expensed as incurred. Thereafter, certain costs such as coding and testing are capitalized until the product is available for general release to customers. The Company uses the working model approach to establish technological feasibility and, to date, no internal costs have been capitalized as software development. In 1995, the Company wrote off purchased software with a cost of $1,037,000 when it determined that it would use an alternative software design in its products. ADVERTISING COSTS The Company expenses the costs of advertising as incurred. Advertising costs aggregated $1,221,000, $1,032,000 and $886,000 for the years ended December 31, 1996, 1995 and 1994, respectively. TRANSLATION OF FOREIGN CURRENCIES The financial statements of the Company's foreign subsidiary, MicroSim Japan, K.K., are translated into U. S. dollars using the exchange rate at each balance sheet date for assets and liabilities and a weighted average exchange rate for each period for revenues, expenses, gains and losses. NET INCOME PER SHARE Net income per share is computed using the weighted average number of common and common equivalent shares outstanding. Common equivalent shares from stock options are excluded from the calculation where their effect is antidilutive.

STOCK OPTION PLAN The Company has elected to follow Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB 25) in accounting for its employee stock options. Under APB 25, because the exercise price of the Company's employee stock options equals the market price of the underlying stock on the date of grant, no compensation expense is recognized. Pro forma information regarding net income and net income per share is required by Statement of Financial Accounting Standard No. 123, Accounting for Stock Based Compensation (SFAS 123), as if the Company had accounted for its employee stock options under the fair value method of that statement. The fair value for options granted was estimated at the date of grant using the Black-Scholes option valuation model. Significant factors used in the valuation model include an assumed weighted average expected life of the option of five years, a risk-free interest rate of 6%, an expected volatility of 50%, and no dividend payments. For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the option's vesting period. F-26 MICROSIM CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) 2. TAXES BASED ON INCOME The Company utilizes the liability method of accounting for income taxes as set forth in Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes. Under the liability method, deferred taxes are determined based on the differences between the financial statement and tax bases of assets and liabilities, using enacted tax rates. The federal and state income tax provisions for the three years ended December 31, 1996 are summarized as follows: 1996 1995 1994 ---- ---- ---- (IN THOUSANDS) Current: Federal................................................ $288 $609 $285 State.................................................. 145 115 32 Foreign................................................ 315 -- -- ---- ---- ---- 748 724 317 Deferred: Federal................................................

Significant components of the Company's net deferred tax assets and liabilities as of December 31, 1996 and 1995 are: 1996 1995 ------- ------- (IN THOUSANDS) Deferred tax assets: Accrued expenses....................................... $ 371 $ 294 Foreign net operating loss carryforward................ 74 -- Accounts receivable and inventory reserves............. 50 30 Foreign tax credit..................................... 47 -- California franchise taxes............................. 27 19 Inventory capitalization............................... 21 17 ------- ------- 590 360 Valuation allowance....................................

A valuation allowance has been recorded to offset the deferred tax asset related to the foreign net operating loss carryforward. Foreign tax credits of $47,000 are available to offset federal tax on foreign source income through 2001. 3. LINE OF CREDIT The Company has a $2,000,000 line of credit agreement with a bank that expires in June 1997. Advances under the line are limited to 80% of eligible accounts receivable, as defined, bear interest at the bank's prime rate and are secured by substantially all the assets of the Company. No amounts were outstanding under the line at December 31, 1996. The loan agreement contains certain restrictive covenants and conditions, including the requirement to maintain certain key financial ratios and minimum levels of working capital and tangible net worth. The agreement further limits the amount of expenditures for repurchase of the Company's common stock, and the amount of indebtedness that may be incurred for future capital investment. At December 31, 1996, the Company was in compliance with all covenants. 4. COMMITMENTS The Company leases facilities and equipment under various lease arrangements. The lease terms include a renewal option for an additional period on the Company's main facility lease. Future minimum lease payments under noncancelable operating lease arrangements are as follows: 1997................................ $222,000 1998................................ 1,000 -------- Total minimum lease payments...... $223,000 ======== F-28 MICROSIM CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) Rental expense under operating leases was approximately $515,000, $463,000 and $455,000 in 1996, 1995 and 1994, respectively. The Company has entered into several license agreements that provide for minimum royalty and maintenance payments through 1997. Royalty expense for the years ended December 31, 1996, 1995 and 1994 was $474,000, $487,000 and $373,000, respectively. 5. CONTRACT PAYABLE The Company purchased software under a noninterest bearing long-term contract payable, which requires payments of $25,000 per month through July 1997. Amounts payable under the contract at December 31, 1996 are net of imputed interest of $3,700. 6. SHAREHOLDERS' EQUITY Employee-shareholders of the Company have entered into stock purchase agreements under which they purchased shares of common stock at fair market value as determined by the Board of Directors. Consideration may include a promissory note which is secured by the shares of stock. Payments on such notes are made by payroll deductions over terms of up to three years. Shares sold to employees are subject to repurchase by the Company, or the remaining shareholders, upon death, disability, or termination of employment. Repurchase prices vary under the terms of the agreements from original cost to current fair market value. During 1995 the Company adopted the 1995 Stock Option Plan under which nonstatutory and incentive stock options may be granted to employees and nonemployees, at a price not less than the fair market value at the date of grant. The Plan allows for the issuance of an aggregate of 300,000 shares of the Company's common stock. The options expire six years from the date of grant and vest over a period of five years. A summary of the Company's stock option activity, and related information for the years ended December 31, follows: 1996 1995 ----------------- ---------------- WEIGHTED WEIGHTED AVERAGE AVERAGE EXERCISE EXERCISE OPTIONS PRICE OPTIONS PRICE ------- -------- ------- -------- Outstanding -- beginning of year.......... 137,500 $ 3.40 -- $ -- Granted................................... 89,100 3.60 137,500 3.40 Forfeited.................................

The weighted average remaining contractual life of options is 4.25 years. Pro forma net income under the provisions of SFAS 123 is $1,004,000 and $1,283,000 for the years ended December 31, 1996 and 1995, respectively. Pro forma net income per share is $.35 and $.45 for the years ended December 31, 1996 and 1995, respectively. Pro forma adjustments may not be representative of amounts in future years because of the cumulative effect of amortized compensation expense over consecutive grant years. F-29 MICROSIM CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) 7. EMPLOYEE BENEFIT PLAN The Company has a defined contribution benefit plan established under Section 401(k) of the Internal Revenue Code.

ARTICLE III Consideration for the Merger 3.1 Conversion. At the Effective Time, each shareholder of MicroSim, and each option holder of MicroSim, shall receive in exchange for his, her, or its "MicroSim Merger Shares" (as defined below) two things: 1) a number of shares of the common stock of OrCAD, $0.01 par value per share ("OrCAD Common Stock), equal to 90% of the Exchange Ratio times that holder's number of MicroSim Merger Shares; and 2) a contract right to receive a number of shares of OrCAD Common Stock equal to that shareholder's and/or option A-2 holder's Pro Rata Share of the Escrowed Merger Consideration. The terms "MicroSim Merger Shares", "Exchange Ratio", "Pro Rata Share" and "Escrowed Merger Consideration" are explained in the following definitions. (a) MicroSim Merger Shares. A "MicroSim Merger Share" is a quantity that bears the relationships defined below to each of the following four (4) classes of outstanding MicroSim common stock or rights to common stock: (i) Fully Vested Common Stock. Each share of fully vested MicroSim Common Stock is equal to one (1) fully vested MicroSim Merger Share. (ii) Unvested Common Stock. Each share of unvested MicroSim Common Stock is equal to .91 fully vested MicroSim Merger Share. (iii) Vested Options. For MicroSim stock options that are "vested", that is, by their terms immediately exercisable on the Closing Date, the total number of shares of MicroSim Common Stock represented by such vested stock options held by each holder of such options shall first be multiplied by the MicroSim Fair Market Value (as defined below). Second, the aggregate exercise price of all included vested options shall be subtracted from the total value identified under the preceding sentence. Third, the difference thus obtained shall be divided by the MicroSim Fair Market Value. The resulting number of shares shall be deemed to be that option holder's MicroSim Merger Shares, with respect to all of that option holder's vested stock options. (iv) Unvested Options. For stock options that are "unvested," that is, by their terms not yet exercisable on the Closing Date, the total number of shares of MicroSim Common Stock represented by such unvested stock options held by each holder of such options shall first be multiplied by the MicroSim Fair Market Value (as defined below). Second, the aggregate exercise price of all included unvested options shall be subtracted from the total value identified under the preceding sentence. Third, the difference thus obtained shall be divided by the MicroSim Fair Market Value. Fourth, the resulting number of shares shall be multiplied by .9. The resulting number of shares shall be deemed to be that option holder's MicroSim Merger Shares, with respect to all of that option holder's unvested stock options. (v) MicroSim Fair Market Value means the Exchange Ratio times the value of one (1) share of OrCAD Common Stock on the Closing Date, which is agreed to be equal to the average of the closing prices per share of OrCAD Common Stock for the ten (10) consecutive trading days ending with the close of trading on the third business day preceding the Closing Date. (b) Exchange Ratio means .825, and represents the agreed-upon ratio at which shares of OrCAD Common Stock will be exchanged for each MicroSim Merger Share. (c) Fixed Merger Consideration means the total number of MicroSim Merger Shares as of the Closing Date, times the Exchange Ratio, times ninety percent (90%). (d) Escrowed Merger Consideration means the total number of MicroSim Merger Shares as of the Closing Date, times the Exchange Ratio, times ten percent (10%). (e) Pro Rata Share means the percentage which the MicroSim Merger Shares held by any given MicroSim shareholder or MicroSim option holder represent of all MicroSim Merger Shares, as of the Closing Date. 3.2 Treasury Shares. Each MicroSim Share issued and held in MicroSim's treasury immediately prior to the Effective Time, if any, shall, by virtue of the Merger and without any action on the part of the holder thereof, cease to be outstanding, shall be cancelled and retired without payment of any consideration therefor, and shall cease to exist. 3.3 Shareholder Rights. From and after the Effective Time, the holders of certificates or options representing MicroSim Shares outstanding immediately prior to the Effective Time (each, a "Shareholder," and collectively, the "Shareholders") shall cease to have any rights with respect to such MicroSim Shares (except A-3 such rights, if any, as they may have as dissenting shareholders under the California Corporations Code) and their sole rights (except as aforesaid) shall be those contract rights which they will have pursuant to this Agreement to receive their Pro Rata Share of the Escrowed Merger Consideration and their Pro Rata Share of the Fixed Merger Consideration. After the Effective Time, each Shareholder (other than dissenting shareholders) shall be entitled, upon surrender of a certificate(s) representing MicroSim Shares outstanding immediately prior to the Effective Time (duly endorsed if required), or options to acquire MicroSim Shares outstanding immediately prior to the Effective Time, together with a properly completed letter of transmittal covering all such shares (with customary representations and warranties regarding the absence of liens, claims and encumbrances on such shares), to receive in exchange therefor (i) a certificate or certificates (as the holder requests) representing that Shareholder's Pro Rata Share of the Fixed Merger Consideration, plus (ii) the contract right as defined in this Agreement to receive that Shareholder's Pro Rata Share of the Escrowed Merger Consideration, subject to the terms and conditions set forth in Article IX hereof. Until so surrendered for exchange, each such certificate representing MicroSim Shares outstanding as aforesaid (other than those of dissenting shareholders) or options to acquire MicroSim Shares outstanding as aforesaid, shall be deemed for all corporate purposes, other than the payment of dividends, to evidence the ownership of the number of shares of OrCAD Common Stock to be delivered and distributed in exchange therefor pursuant to this Article 3. Unless and until any such certificate representing MicroSim Shares outstanding as aforesaid or option to acquire MicroSim Shares outstanding as aforesaid shall be so surrendered, no dividend payable to holders of record of OrCAD Common Stock at or after the Effective Time shall be paid to the holder of such certificate or option but upon surrender thereof there shall be paid to the holder of record immediately prior to the Effective Time of such surrendered certificate or option the dividends (without interest) that have theretofore become payable with respect to the OrCAD Common Stock after the Effective Time, deliverable and distributable in exchange therefor pursuant to this Article III; provided, however, that if by reason of the escheat or other laws of any state having jurisdiction in the premises, OrCAD is required to pay such state all or any part of such dividends which have become payable, the amount of dividends which would otherwise be payable upon surrender of any such certificate representing MicroSim Shares outstanding as aforesaid or option to acquire MicroSim Shares outstanding as aforesaid shall be reduced by the amount so paid pursuant to such escheat or other laws. 3.4 Dissenters' Rights. MicroSim Shares held by Shareholders who have properly exercised dissenters' rights with respect thereto in accordance with Sections 1300 through 1312 of the California Corporations Code (collectively, the "Dissenting Shares") shall not be converted into the right to receive OrCAD Common Stock, but such Shareholders shall be entitled to receive payment of the fair market value of the Dissenting Shares in accordance with the provisions of the California Corporations Code, except that any Dissenting Shares held by a Shareholder who shall thereafter withdraw such demand for appraisal of his or her MicroSim Shares or otherwise lose the right to such payment as provided in the California Corporations Code, shall thereupon be deemed to have been converted into, as of the Effective Time, the right to receive OrCAD Common Stock as provided herein, without any interest thereon. If any holder of MicroSim Shares shall demand to be paid the "fair market value" of his or her shares, as provided in Section 1301(b) of the California Corporations Code, MicroSim shall give OrCAD prompt written notice thereof and OrCAD shall have the right to participate in all negotiations and proceedings with respect to any such demands. MicroSim shall not, except with the prior written consent of OrCAD, voluntarily make any payment with respect to, or settle or offer to settle, any such demand for payment demands. MicroSim shall not, except with the prior written consent of OrCAD, voluntarily make any payment with respect to, or settle or offer to settle, any such demand for payment. 3.5 Fractional Shares. No fractional shares of OrCAD Common Stock shall be issued in the Merger. In lieu of the issuance of any such fractional shares, OrCAD shall pay to each Shareholder of MicroSim who otherwise would be entitled to receive a fractional share of OrCAD's Common Stock (after taking into account all OrCAD Common Stock into which such Shareholder's MicroSim Shares were converted pursuant to this Article III) an amount in cash (rounded to the nearest whole cent) determined by multiplying (i) the fair market value (as hereinafter defined) of a share of OrCAD's Common Stock by (ii) the fraction of a share of OrCAD's A-4 Common Stock which such holder would otherwise be entitled to receive pursuant to this Article 3. The fair market value of a share of OrCAD's Common Stock shall be the average of the closing prices for one (1) share of OrCAD Common Stock for the last ten (10) consecutive trading days ending with the close of trading on the third business day preceding the Closing Date. 3.6 Lost Certificates. In the event any certificate representing MicroSim Shares or option to acquire MicroSim Shares (each, a "Certificate") shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and indemnity against any claim that may be made against OrCAD with respect to such Certificate, and, if required by OrCAD, the posting by such person of a bond in such amount as OrCAD may determine is reasonably necessary in connection with such indemnity, OrCAD will issue in exchange for such lost, stolen or destroyed Certificate the OrCAD Common Stock, and cash in lieu of any fractional shares, deliverable in respect thereof pursuant to this Agreement. 3.7 Escrow Deposit. Promptly following the Closing, OrCAD shall deposit in escrow pursuant to Article IX hereof, the number of shares of OrCAD Common Stock constituting the Escrowed Merger Consideration. Such shares shall be issued in the name of the Escrow Agent, "as Escrow Agent under that Escrow Agreement dated" the Closing Date or otherwise with equivalent effect. Such shares shall be held for the purposes described in Article IX and the Escrow Agreement (as hereinafter defined), and released to OrCAD and/or the Shareholders in accordance with the provisions of Article IX and the Escrow Agreement.

(b) From, out of, and to the extent of the resources constituting the Escrow Fund, the Indemnified Party shall be held harmless from, against and in respect of, any and all Damages incurred by the Indemnified Party arising from or in connection with (i) any inaccuracy or other breach of any representation or warranty made by MicroSim in Article IV of this Agreement and not disclosed on the MicroSim Disclosure Schedule, or (ii) any failure of MicroSim to perform any agreement or covenant required by this Agreement to be performed by it.

If, on the Expiration Date (as hereinafter defined), there exists any Claim which was timely asserted by the Indemnified Party but which is not then finally resolved and discharged, there shall remain in the Escrow out of the Escrow Fund an aggregate number of Shares of OrCAD common stock with an aggregate fair market value (determined as of the Closing Date) equal to the reasonable estimate (determined in accordance with Section 9.3) of the amount of Damages asserted to be caused by such Claim.

Any Claim for Damages that is less than Five Thousand and 00/100 Dollars ($5,000.00) will not be counted toward the A-45 Deductible. Except with respect to Section 8.4(d), MicroSim's liability under this Agreement--whether pursuant to its indemnity obligations under Section 9.1(b) or otherwise--will not exceed (in the aggregate) the value of the Escrowed Merger Consideration as valued herein. 9.3 Notice of Claim. The Indemnified Party shall promptly notify the Shareholder Representatives in writing of any Claim asserted against or imposed upon or incurred by it that might give rise to any indemnity obligation hereunder (a "Notice of Claim"), specifying the basis and, if possible, a reasonable estimate of the amount (as determined in good faith by the Board of Directors of OrCAD) of Damages sought by such Indemnified Party on account thereof and in reasonable detail such information as the Indemnified Party may have with respect to the matter that is the subject of the Notice of Claim (including copies of any summons, complaint or other pleading that may have been served on it and any written claim, demand, invoice, billing or other document evidencing or asserting the same). The Indemnified Party shall not be entitled to give a Notice of Claim after the Expiration Date. The date of a Notice of Claim shall mean (a) the date of the postmark on the registered or certified mail containing the Notice of Claim, or (b) if the Notice of Claim is transmitted by courier, the date of its delivery to the courier by the Indemnified Party or (c) if the Notice of Claim is personally delivered, the date of such personal delivery. 9.4 Defense and Settlement of Claims. The Shareholder Representatives shall have the right (without prejudice to the right of the Indemnified Party to participate at its own expense through counsel of its own choosing) to defend against any Claim that is the subject of a Notice of Claim and to pay the expenses thereof (including the expenses of counsel of their own choosing), and to control such defense if they provide written notice of their intention to do so within 15 business days of receipt of the Notice of Claim. The Indemnified Party shall cooperate fully in the defense of such Claim and shall make available to the Shareholder Representatives or their counsel all pertinent information under its control relating thereto. The Indemnified Party shall have the right to elect to settle any such Claim; provided, however, there shall be no indemnification obligation with respect to any monetary payment to any third party required by such settlement unless a majority of the Shareholder Representatives shall have consented in writing thereto, which consent shall not be unreasonably withheld. 9.5 Jurisdiction.

("OrCAD"), OCA Merger Corporation, a wholly owned subsidiary of OrCAD ("Merger Sub"), and MicroSim Corporation ("MicroSim") have entered into an Agreement and Plan of Merger, dated as of the date hereof (the "Merger Agreement"), which provides, among other things, for the merger (the "Merger") of Merger Sub with and into MicroSim. Pursuant to the Merger, each issued and outstanding share of common stock of MicroSim (the "MicroSim Common Stock"), other than shares held in treasury or held by OrCAD or any subsidiary or affiliate of OrCAD or MicroSim or as to which dissenters' rights have been perfected, shall be converted automatically into the right to receive 0.825 of a share (the "Exchange Ratio") of common stock of OrCAD, $0.01 par value per share (the "OrCAD Common Stock"). The terms and conditions of the Merger are more fully set forth in the Merger Agreement. You have requested our opinion as to whether, as of this date, the Exchange Ratio pursuant to the Merger Agreement is fair from a financial point of view to the holders of OrCAD Common Stock. For purposes of the opinion set forth herein, we have: 1. analyzed certain internal financial statements and other financial and operating data concerning MicroSim prepared by the management of MicroSim; 2. analyzed certain financial projections relating to MicroSim prepared by the management of MicroSim; 3. discussed the past and current operations and financial condition and the prospects of MicroSim, including information relating to certain strategic, financial, and operational benefits anticipated from the Merger, with senior managers of MicroSim; 4. analyzed certain publicly available financial statements and other information of OrCAD; 5. analyzed certain internal financial statements and other financial and operating data concerning OrCAD prepared by the management of OrCAD; 6. discussed the past and current operations and financial condition and the prospects of OrCAD, including information relating to certain strategic, financial, and operational benefits anticipated from the Merger, with senior managers of OrCAD; 7. analyzed the pro forma impact of the Merger on the earnings per share and consolidated capitalization of OrCAD; 8. reviewed the reported prices and trading activity for the OrCAD Common Stock; 9. compared the financial performance of MicroSim with that of certain other publicly traded companies (which we deemed to be relevant) and their securities; B-1 10. compared the financial performance of OrCAD and the prices and trading activity of the OrCAD Common Stock with that of certain other publicly-traded companies (which we deemed to be relevant) and their securities; 11. reviewed the financial terms, to the extent publicly available, of certain merger and acquisition transactions (which we deemed to be relevant); 12. reviewed and discussed with the senior managers of OrCAD (i) the strategic rationale for the Merger and their assessment of the synergies and other benefits expected to be derived from the Merger and (ii) certain alternatives to the Merger; 13. participated in discussions and negotiations among representatives of MicroSim and OrCAD and their financial and legal advisors; 14. reviewed the Merger Agreement; and 15. performed such other analyses and considered such other factors as we have deemed appropriate. We have assumed and relied upon, without independent verification, the accuracy and completeness of the information reviewed by us for the purposes of this opinion. With respect to the financial projections, we have assumed they have been reasonably prepared on bases reflecting the best currently available estimated and judgments of the future financial performance of MicroSim and OrCAD. With respect to the information furnished by OrCAD and MicroSim, and with respect to the information discussed with the managers of OrCAD and MicroSim regarding their views of future operations, we have assumed that such information has been reasonably prepared and reflects the best currently available estimates and judgments of OrCAD's and MicroSim's management. For purposes of this opinion, we have also relied upon, without independent verification, the assessment by OrCAD's and MicroSim's managers of the cost savings and other synergies as well as the strategic and other benefits expected to be derived from the Merger. We have also relied upon, without independent verification, the assessment by OrCAD's management of MicroSim's technology and competitive position. We have not made any independent valuation or appraisal of the assets, liabilities, or technology of OrCAD or MicroSim, respectively, nor have we been furnished with any such appraisals. We have assumed that the Merger will be accounted for as a "pooling-of-interests" business combination in accordance with U.S. Generally Accepted Accounting Principles and as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. We have assumed that the Merger will be consummated on the terms set forth in the Merger Agreement without waiver or amendment of any of the terms or conditions thereof. Our opinion is necessarily based on economic, market, and other conditions in effect on, and the information made available to us as of the date hereof. In rendering this opinion, we are not expressing any opinion as to the price at which the OrCAD Common Stock will actually trade at any time. We have acted as financial advisor to the Board of Directors of OrCAD in connection with this transaction and will receive fees from the Company for our services, a significant portion of which is contingent upon the consummation of the Merger. In addition, the Company has agreed to indemnify us for certain liabilities that may arise out of the rendering of this opinion. A principal of Redwood Partners LLC is also a member of the Board of Directors of OrCAD, principals of Redwood Partners LLC hold positions in OrCAD Common Stock, and a predecessor of Redwood Partners LLC was the largest stockholder of OrCAD until September 1996. It is understood that this letter is for the information of the Board of Directors of OrCAD and may not be used for any other purposes without our prior written consent, except that this opinion may be included in its entirety in any filing made by OrCAD, with the Securities and Exchange Commission with respect to the transactions contemplated by the Merger Agreement. In addition, our opinion does not address the underlying decision by the Company to engage in the Merger and we express no recommendation or opinion as to how the stockholders of OrCAD should vote at the stockholders' meeting held in connection with the Merger. B-2 Based upon and subject to the foregoing, we are of the opinion on the date hereof that the Exchange Ratio pursuant to the Merger Agreement is fair from a financial point of view to the holders of OrCAD Common Stock. Yours sincerely, Redwood Partners LLC /s/ Jim Timmins By:__________________________________ Jim Timmins, Managing Director B-3 APPENDIX C CALIFORNIA CORPORATIONS CODE CHAPTER 13. DISSENTERS' RIGHTS S 1300. REORGANIZATION OR SHORT-FORM MERGER; DISSENTING SHARES; CORPORATE PURCHASE AT FAIR MARKET VALUE; DEFINITIONS (a) If the approval of the outstanding shares (Section 152) of a corporation is required for a reorganization under subdivisions (a) and (b) or subdivision (e) or (f) of Section 1201, each shareholder of the corporation entitled to vote on the transaction and each shareholder of a subsidiary corporation in a short-form merger may, by complying with this chapter, require the corporation in which the shareholder holds shares to purchase for cash at their fair market value the shares owned by the shareholder which are dissenting shares as defined in subdivision (b). The fair market value shall be determined as of the day before the first announcement of the terms of the proposed reorganization or short-form merger, excluding any appreciation or depreciation in consequence of the proposed action, but adjusted for any stock split, reverse stock split, or share dividend which becomes effective thereafter. (b) As used in this chapter, "dissenting shares" means shares which come within all of the following descriptions: (1) Which were not immediately prior to the reorganization or short-form merger either (A) listed on any national securities exchange certified by the Commissioner of Corporations under subdivision (o) of Section 25100 or (B) listed on the list of OTC margin stocks issued by the Board of Governors of the Federal Reserve System, and the notice of meeting of shareholders to act upon the reorganization summarizes this section and Sections 1301, 1302, 1303 and 1304; provided, however, that this provision does not apply to any shares with respect to which there exists any restriction on transfer imposed by the corporation or by any law or regulation; and provided, further, that this provision does not apply to any class of shares described in subparagraph (A) or (B) if demands for payment are filed with respect to 5 percent or more of the outstanding shares of that class. (2) Which were outstanding on the date for the determination of shareholders entitled to vote on the reorganization and (A) were not voted in favor of the reorganization or, (B) if described in subparagraph (A) or (B) of paragraph (1) (without regard to the provisos in that paragraph), were voted against the reorganization, or which were held of record on the effective date of a short-form merger; provided, however, that subparagraph (A) rather than subparagraph (B) of this paragraph applies in any case where the approval required by Section 1201 is sought by written consent rather than at a meeting. (3) Which the dissenting shareholder has demanded that the corporation purchase at their fair market value, in accordance with Section 1301. (4) Which the dissenting shareholder has submitted for endorsement, in accordance with Section 1302. (c) As used in this chapter, "dissenting shareholder" means the recordholder of dissenting shares and includes a transferee of record. S 1301. NOTICE TO HOLDERS OF DISSENTING SHARES IN REORGANIZATIONS; DEMAND FOR PURCHASE; TIME; CONTENTS (a) If, in the case of a reorganization, any shareholders of a corporation have a right under Section 1300, subject to compliance with paragraphs (3) and (4) of subdivision (b) thereof, to require the corporation to purchase their shares for cash, such corporation shall mail to each such shareholder a notice of the approval of the reorganization by its outstanding shares (Section 152) within 10 days after the date of such approval, accompanied by a copy of Sections 1300, 1302, 1303, 1304 and this section, a statement of the price determined by the corporation to represent the fair market value of the dissenting shares, and a brief description of the procedure to be followed if the shareholder desires to exercise the shareholder's right under such sections. The statement of price constitutes an offer by the corporation to purchase at the price stated any dissenting shares as defined in subdivision (b) of Section 1300, unless they lose their status as dissenting shares under Section 1309. C-1 (b) Any shareholder who has a right to require the corporation to purchase the shareholder's shares for cash under Section 1300, subject to compliance with paragraphs (3) and (4) of subdivision (b) thereof, and who desires the corporation to purchase such shares shall make written demand upon the corporation for the purchase of such shares and payment to the shareholder in cash of their fair market value. The demand is not effective for any purpose unless it is received by the corporation or any transfer agent thereof (1) in the case of shares described in clause (i) or (ii) of paragraph (1) of subdivision (b) of Section 1300 (without regard to the provisos in that paragraph), not later than the date of the shareholders' meeting to vote upon the reorganization, or (2) in any other case within 30 days after the date on which the notice of the approval by the outstanding shares pursuant to subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was mailed to the shareholder. (c) The demand shall state the number and class of the shares held of record by the shareholder which the shareholder demands that the corporation purchase and shall contain a statement of what such shareholder claims to be the fair market value of those shares as of the day before the announcement of the proposed reorganization or short-form merger. The statement of fair market value constitutes an offer by the shareholder to sell the shares at such price. S 1302. SUBMISSION OF SHARE CERTIFICATES FOR ENDORSEMENT; UNCERTIFICATED SECURITIES Within 30 days after the date on which notice of the approval by the outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, the shareholder shall submit to the corporation at its principal office or at the office of any transfer agent thereof, (a) if the shares are certificated securities, the shareholder's certificates representing any shares which the shareholder demands that the corporation purchase, to be stamped or endorsed with a statement that the shares are dissenting shares or to be exchanged for certificates of appropriate denomination so stamped or endorsed or (b) if the shares are uncertificated securities, written notice of the number of shares which the shareholder demands that the corporation purchase. Upon subsequent transfers of the dissenting shares on the books of the corporation, the new certificates, initial transaction statement, and other written statements issued therefor shall bear a like statement, together with the name of the original dissenting holder of the shares. S 1303. PAYMENT OF AGREED PRICE WITH INTEREST; AGREEMENT FIXING FAIR MARKET VALUE; FILING; TIME OF PAYMENT (a) If the corporation and the shareholder agree that the shares are dissenting shares and agree upon the price of the shares, the dissenting shareholder is entitled to the agreed price with interest thereon at the legal rate on judgments from the date of the agreement. Any agreements fixing the fair market value of any dissenting shares as between the corporation and the holders thereof shall be filed with the secretary of the corporation. (b) Subject to the provisions of Section 1306, payment of the fair market value of dissenting shares shall be made within 30 days after the amount thereof has been agreed or within 30 days after any statutory or contractual conditions to the reorganization are satisfied, whichever is later, and in the case of certificated securities, subject to surrender of the certificates therefor, unless provided otherwise by agreement. S 1304. ACTION TO DETERMINE WHETHER SHARES ARE DISSENTING SHARES OR FAIR MARKET VALUE; LIMITATION; JOINDER; CONSOLIDATION; DETERMINATION OF ISSUES; APPOINTMENT OF APPRAISERS (a) If the corporation denies that the shares are dissenting shares, or the corporation and the shareholder fail to agree upon the fair market value of the shares, then the shareholder demanding purchase of such shares as dissenting shares or any interested corporation, within six months after the date on which notice of the approval by the outstanding shares (Section 152) or notice pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but not thereafter, may file a complaint in the superior court of the proper county praying the court to determine whether the shares are dissenting shares or the fair market value of the dissenting shares or both or may intervene in any action pending on such a complaint. C-2 (b) Two or more dissenting shareholders may join as plaintiffs or be joined as defendants in any such action and two or more such actions may be consolidated. (c) On the trial of the action, the court shall determine the issues. If the status of the shares as dissenting shares is in issue, the court shall first determine that issue. If the fair market value of the dissenting shares is in issue, the court shall determine, or shall appoint one or more impartial appraisers to determine, the fair market value of the shares. S 1305. REPORT OF APPRAISERS; CONFIRMATION; DETERMINATION BY COURT; JUDGMENT; PAYMENT; APPEAL; COSTS (a) If the court appoints an appraiser or appraisers, they shall proceed forthwith to determine the fair market value per share. Within the time fixed by the court, the appraisers, or a majority of them, shall make and file a report in the office of the clerk of the court. Thereupon, on the motion of any party, the report shall be submitted to the court and considered on such evidence as the court considers relevant. If the court finds the report reasonable, the court may confirm it. (b) If a majority of the appraisers appointed fail to make and file a report within 10 days from the date of their appointment or within such further time as may be allowed by the court or the report is not confirmed by the court, the court shall determine the fair market value of the dissenting shares. (c) Subject to the provisions of Section 1306, judgment shall be rendered against the corporation for payment of an amount equal to the fair market value of each dissenting share multiplied by the number of dissenting shares which any dissenting shareholder who is a party, or who has intervened, is entitled to require the corporation to purchase, with interest thereon at the legal rate from the date on which judgment was entered. (d) Any such judgment shall be payable forthwith with respect to uncertificated securities and, with respect to certificated securities, only upon the endorsement and delivery to the corporation of the certificates for the shares described in the judgment. Any party may appeal from the judgment. (e) The costs of the action, including reasonable compensation to the appraisers to be fixed by the court, shall be assessed or apportioned as the court considers equitable, but, if the appraisal exceeds the price offered by the corporation, the corporation shall pay the costs (including in the discretion of the court attorneys' fees, fees of expert witnesses and interest at the legal rate on judgments from the date of compliance with Sections 1300, 1301 and 1302 if the value awarded by the court for the shares is more than 125 percent of the price offered by the corporation under subdivision (a) of Section 1301). S 1306. PREVENTION OF IMMEDIATE PAYMENT; STATUS AS CREDITORS; INTEREST To the extent that the provisions of Chapter 5 prevent the payment to any holders of dissenting shares of their fair market value, they shall become creditors of the corporation for the amount thereof together with interest at the legal rate on judgments until the date of payment, but subordinate to all other creditors in any liquidation proceeding, such debt to be payable when permissible under the provisions of Chapter 5. S 1307. DIVIDENDS ON DISSENTING SHARES Cash dividends declared and paid by the corporation upon the dissenting shares after the date of approval of the reorganization by the outstanding shares (Section 152) and prior to payment for the shares by the corporation shall be credited against the total amount to be paid by the corporation therefor. S 1308. RIGHTS OF DISSENTING SHAREHOLDERS PENDING VALUATION; WITHDRAWAL OF DEMAND FOR PAYMENT Except as expressly limited in this chapter, holders of dissenting shares continue to have all the rights and privileges incident to their shares, until the fair market value of their shares is agreed upon or determined. A dissenting shareholder may not withdraw a demand for payment unless the corporation consents thereto. C-3 S 1309. TERMINATION OF DISSENTING SHARE AND SHAREHOLDER STATUS Dissenting shares lose their status as dissenting shares and the holders thereof cease to be dissenting shareholders and cease to be entitled to require the corporation to purchase their shares upon the happening of any of the following: (a) The corporation abandons the reorganization. Upon abandonment of the reorganization, the corporation shall pay on demand to any dissenting shareholder who has initiated proceedings in good faith under this chapter all necessary expenses incurred in such proceedings and reasonable attorneys' fees. (b) The shares are transferred prior to their submission for endorsement in accordance with Section 1302 or are surrendered for conversion into shares of another class in accordance with the articles. (c) The dissenting shareholder and the corporation do not agree upon the status of the shares as dissenting shares or upon the purchase price of the shares, and neither files a complaint or intervenes in a pending action as provided in Section 1304, within six months after the date on which notice of the approval by the outstanding shares or notice pursuant to subdivision (i) of Section 1110 was mailed to the shareholder. (d) The dissenting shareholder, with the consent of the corporation, withdraws the shareholder's demand for purchase of the dissenting shares. S 1310. SUSPENSION OF RIGHT TO COMPENSATION OR VALUATION PROCEEDINGS; LITIGATION OF SHAREHOLDERS' APPROVAL If litigation is instituted to test the sufficiency or regularity of the votes of the shareholders in authorizing a reorganization, any proceedings under Sections 1304 and 1305 shall be suspended until final determination of such litigation. S 1311. EXEMPT SHARES This chapter, except Section 1312, does not apply to classes of shares whose terms and provisions specifically set forth the amount to be paid in respect to such shares in the event of a reorganization or merger. S 1312. RIGHT OF DISSENTING SHAREHOLDER TO ATTACK, SET ASIDE OR RESCIND MERGER OR REORGANIZATION; RESTRAINING ORDER OR INJUNCTION; CONDITIONS (a) No shareholder of a corporation who has a right under this chapter to demand payment of cash for the shares held by the shareholder shall have any right at law or in equity to attack the validity of the reorganization or short-form merger, or to have the reorganization or short-form merger set aside or rescinded, except in an action to test whether the number of shares required to authorize or approve the reorganization have been legally voted in favor thereof; but any holder of shares of a class whose terms and provisions specifically set forth the amount to be paid in respect to them in the event of a reorganization or short-form merger is entitled to payment in accordance with those terms and provisions or, if the principal terms of the reorganization are approved pursuant to subdivision (b) of Section 1202, is entitled to payment in accordance with the terms and provisions of the approved reorganization. (b) If one of the parties to a reorganization or short-form merger is directly or indirectly controlled by, or under common control with, another party to the reorganization or short-form merger, subdivision (a) shall not apply to any shareholder of such party who has not demanded payment of cash for such shareholder's shares pursuant to this chapter; but if the shareholder institutes any action to attack the validity of the reorganization or short- form merger or to have the reorganization or short-form merger set aside or rescinded, the shareholder shall not thereafter have any right to demand payment of cash for the shareholder's shares pursuant to this chapter. The court in any action attacking the validity of the reorganization or short-form merger or to have the reorganization or short-form merger set aside or rescinded shall not restrain or enjoin the consummation of the C-4 transaction except upon 10 days' prior notice to the corporation and upon a determination by the court that clearly no other remedy will adequately protect the complaining shareholder or the class of shareholders of which such shareholder is a member. (c) If one of the parties to a reorganization or short-form merger is directly or indirectly controlled by, or under common control with, another party to the reorganization or short-form merger, in any action to attack the validity of the reorganization or short-form merger or to have the reorganization or short-form merger set aside or rescinded, (1) a party to a reorganization or short-form merger which controls another party to the reorganization or short-form merger shall have the burden of proving that the transaction is just and reasonable as to the shareholders of the controlled party, and (2) a person who controls two or more parties to a reorganization shall have the burden of proving that the transaction is just and reasonable as to the shareholders of any party so controlled. C-5 PART II INFORMATION NOT REQUIRED IN PROSPECTUS ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS. As a Delaware corporation OrCAD is subject to the General Corporation Law of the State of Delaware ("General Corporation Law") and the exculpation from liability and indemnification provisions contained therein. In accordance with Section 102 of the General Corporation Law, Article VII of OrCAD's Restated Certificate of Incorporation (the "Certificate") eliminates the liability of OrCAD's directors to OrCAD or its stockholders for breach of fiduciary duty as a director, except for any liability related to breach of the duty of loyalty, acts or omissions not in good faith which involve intentional misconduct or a knowing violation of law, unlawful payment of dividends or unlawful stock purchase or redemption, and certain other liabilities. Section 145 of the General Corporation Law allows corporations to indemnify their directors and officers against liability where the director or officer has acted in good faith and with a reasonable belief that actions taken were in the best interests of the corporation or at least not adverse to the corporation's best interest and, if in a criminal proceeding, the individual had no reasonable cause to believe the conduct in question was unlawful. Under the General Corporation Law, corporations may not indemnify against liability in connection with a claim by or in the right of the corporation but may indemnify against the reasonable expenses associated with the defense of such claims. Corporations also may not indemnify against breaches of the duty of loyalty. The General Corporation Law provides for mandatory indemnification of directors against all reasonable expenses incurred in the successful defense of any claim made or threatened whether or not such claim was by or in the right of the corporation. Finally, a court may order indemnification if it determines that the director or officer is fairly and reasonably entitled to indemnification in view of all the relevant circumstances whether or not the director or officer met the good faith and reasonable belief standards of conduct set out in the statute. The General Corporation Law also provides that the statutory indemnification provisions are not deemed exclusive of any other rights to which directors or officers may be entitled under a corporation's bylaws, any agreement, general or specific action of the board of directors, vote of stockholders or otherwise. The Restated Bylaws require OrCAD to indemnify its directors and officers to the fullest extent not prohibited by law. In addition, the Restated Bylaws deem that all rights to indemnification under the Restated Bylaws are deemed to be contractual rights and are to be effective to the same extent as if provided for in a contract between OrCAD and the director or officer who serves in such capacity. OrCAD has entered into indemnity agreements with each executive officer of OrCAD and each member of OrCAD's Board of Directors. These indemnity agreements provide for indemnification of the indemnitee to the fullest extent allowed by law. ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES.

UNDERTAKINGS. (a) 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 the 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 the 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 the 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; and (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. (b) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this Registration Statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form. (c) The registrant undertakes that every prospectus: (i) that is filed pursuant to paragraph (b) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes 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. (d) 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 Act 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, 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 Act and will be governed by the final adjudication of such issue. (e) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request. (f) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
