5 6 ASPEN TECHNOLOGY, INC. NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS MARCH 31, 1998 (UNAUDITED) 1. BASIS OF PRESENTATION In the opinion of management, the accompanying consolidated condensed financial statements have been prepared in conformity with generally accepted accounting principles and include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation. The results of operations for the three and nine month periods ended March 31, 1998 are not necessarily indicative of the results to be expected for the full year. It is suggested that these interim consolidated condensed financial statements be read in conjunction with the audited consolidated financial statements for the year ended June 30, 1997, which are contained in the Company's Form 10-K, as previously filed with the Securities and Exchange Commission. 2. ACCOUNTING POLICIES (a) Revenue Recognition The Company recognizes revenue from software licenses upon the shipment of its products, pursuant to a signed noncancelable license agreement. In the case of license renewals, revenue is recognized upon execution of the renewal license agreement. The Company has no significant vendor obligations or collectibility risk associated with its product sales. The Company recognizes revenue from postcontract customer support ratably over the period of the postcontract arrangement. The Company accounts for insignificant vendor obligations by deferring a portion of the revenue and recognizing it either ratably as the obligations are fulfilled or when the related services are performed. If significant application development services are performed in connection with the purchase of a license, the license fees are recognized as the application development services are performed. Service revenues from fixed-price contracts are recognized on the percentage-of-completion method, measured by the percentage of costs (primarily labor) incurred to date as compared to the estimated total costs (primarily labor) for each contract. When a loss is anticipated on a contract, the full amount thereof is provided currently. Service revenues from time-and-expense contracts and consulting and training revenue are recognized as the related services are performed. 6 7 Services that have been performed but for which billings have not been made are recorded as unbilled services, and billings that have been recorded before the services have been performed are recorded as unearned revenue in the accompanying consolidated balance sheets. Installments receivable represent the present value of future payments related to the financing of noncancelable term license agreements that provide for payment in installments over a one- to five-year period. A portion of the revenue from each installment agreement is recognized as interest income in the accompanying consolidated condensed statements of income. The interest rates in effect for the three and nine months ended March 31, 1997 were 11% and 8.5% and for the three and nine months ended March 31, 1998 was 8.5%. (b) Computer Software Development Costs In compliance with Statement of Financial Accounting Standards (SFAS) No. 86, "Accounting for the Costs of Computer Software to be Sold, Leased or Otherwise Marketed", certain computer software development costs are capitalized in the accompanying consolidated condensed balance sheets. Capitalization of computer software development costs begins upon the establishment of technological feasibility and ends upon market introduction. Amortization of capitalized computer software development costs is included in cost of revenues and is provided on a product-by-product basis at the greater of the amount computed using (a) the ratio of current gross revenues for a product to the total of current and anticipated future gross revenues or (b) the straight-line method over the remaining estimated economic life of the product, not to exceed three years. Total amortization expense charged to operations in the three and nine month periods ended March 31, 1998 was approximately $275,000 and $709,000 as compared to $278,000 and $738,000 for the three and nine month periods ended March 31, 1997. In March 1998, the American Institute of Certified Public Accountants ("AICPA") issued Statement of Position 98-1 "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use" ("SOP98-1"). SOP98-1 requires computer software costs associated with internal use software to be expensed as incurred until certain capitalization criteria are met. The Company will adopt SOP98-1 prospectively beginning January 1, 1999. Adoption of this Statement will not have a material impact on the Company's consolidated financial position or results of operations. 7 8 (c) Net Income Per Share In February 1997, the Financial Accounting Standards Board issued SFAS No. 128, Earnings Per Share. This Statement establishes standards for computing and presenting earnings per share and applies to entities with publicly traded common stock or potential common stock. SFAS 128 is effective for financial statements for both interim and annual periods ending after December 15, 1997. Basic earnings per share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the dilution of potentially dilutive securities, primarily stock options, based on the treasury stock method. As required, the Company has adopted SFAS 128 effective for the quarter ending December 31, 1997 and has restated all prior periods. Basic and diluted weighted average shares outstanding as required by SFAS No. 128 are as follows (in thousands):
Three Months Ended Nine Months Ended March 31, March 31, March 31, March 31, 1998 1997 1998 1997 --------- --------- --------- --------- Basic weighted average shares outstanding 20,895 19,787 20,629 19,532 Weighted average common equivalent shares 1,467 1,360 _1,331 1,406 ------ ------ ------ ------ Diluted weighted average shares outstanding 22,362 21,147 21,960 20,938 ------ ------ ------ ------
(d) Investments The Company accounts for its investments in accordance with SFAS No. 115, "Accounting for Certain Investments in Debt and Equity Securities". Under SFAS No. 115, securities purchased to be held for indefinite periods of time, and not intended at the time of purchase to be held until maturity, are classified as available-for-sale securities. Securities classified as available-for-sale are required to be recorded at market value in the financial statements. Unrealized gains and losses have been accounted for as a separate component of stockholders' equity. Investments held as of March 31, 1998 consist of $1,202,000 in money market accounts and $5,407,000 in bonds. 8 9 3. SALE OF INSTALLMENTS RECEIVABLE The Company sold, with limited recourse, certain of its installment contracts to two financial institutions for approximately $17.1 million and $44.1 million during the three and nine month periods ended March 31, 1998. The financial institutions have partial recourse to the Company only upon non-payment by the customer under the installments receivable. The amount of recourse is determined pursuant to the provisions of the Company's contracts with the financial institutions and varies depending upon whether the customers under the installment contracts are foreign or domestic entities. Collections of these receivables reduce the Company's recourse obligations, as defined. At March 31, 1998, the balance of the uncollected principal portion of all contracts sold was $87.7 million. The Company's potential recourse obligation related to these contracts is approximately $5.0 million. In addition, the Company is obligated to pay additional costs to the financial institutions in the event of default by the customer. 4. ACQUISITIONS (a) Special Analysis and Simulation Technologies, Ltd. ("SAST") On August 28, 1997, the Company acquired 100% of the outstanding shares of common stock of SAST, a vendor of dynamic simulation and operator training services and applications. The Company exchanged 288,330 shares of its common stock valued at approximately $10.2 million and paid approximately $841,000 in cash for all outstanding shares of SAST common stock. The acquisition has been accounted for as a pooling of interests. This transaction is immaterial to the Company's financial position and results of operations, and accordingly the historical financial statements have not been restated. (b) NeuralWare, Inc. On August 27, 1997 the Company acquired 100% of the outstanding shares of common stock of NeuralWare, Inc., a provider of neural net technology. The Company exchanged 26,502 shares of its common stock for all outstanding shares of NeuralWare, Inc. common stock. The acquisition has been accounted for as a pooling of interests. This transaction is immaterial to the Company's financial position and results of operations, and accordingly the historical financial statements have not been restated. (c) CIMTECH S.A.-N.V. ("CIMTECH") On February 27, 1998, the Company acquired 100% of the outstanding shares of common stock of CIMTECH, a European supplier of process information management systems. The Company exchanged 118,299 shares of its common stock valued at approximately $4.7 million, for all the outstanding shares of CIMTECH stock. The acquisition has been accounted for as a pooling of interests. This transaction is immaterial to the Company's financial position and results of operations, and accordingly the historical financial statements have not been restated. 9 10 (d) Contas Process Control S.r.L. ("Contas") On February 27, 1998, the Company acquired 100% of the outstanding shares of common stock of Contas, a consulting firm that specializes in advanced control and optimization for the Italian petroleum refining market. The Company exchanged 21,975 shares of its common stock for all the outstanding shares of Contas. The acquisition has been accounted for as a pooling of interests. This transaction is immaterial to the Company's financial position and results of operations, and accordingly the historical financial statements have not been restated. (e) IISYS, Inc. ("IISYS") On March 6, 1998, the Company acquired 100% of the outstanding common stock of IISYS, a developer of advanced software technology used by process manufacturers to collect, reconcile and report yield-accounting information. The Company paid approximately $8.4 million in cash and assumed $1.6 million in debt. This acquisition was accounted for as a purchase. The portion of the purchase price allocated to in-process research and development was based upon an independent appraisal. Such in-process research and development projects had not reached technological feasibility and had no alternative future use. As a result, the Company recognized a one-time charge of approximately $8.5 million during the quarter ended March 31, 1998. The remainder of the purchase price has been allocated to various assets based on their fair values. (f) Zyqad Limited ("Zyqad") On March 16, 1998, the Company acquired 100% of the outstanding shares of common stock of Zyqad, a company that provides software for integrating, automating and managing workflow between engineers designing new process plants or improving existing facilities. The Company exchanged 171,337 shares of its common stock valued at approximately $6.3 million for all the outstanding shares of Zyqad. The acquisition has been accounted for as a pooling of interests. This transaction is immaterial to the Company's financial position and results of operations, and accordingly the historical financial statements have not been restated. 10 11 (g) Chesapeake Decision Sciences, Inc. ("Chesapeake") On April 28, 1998, the Company signed a definitive agreement to purchase 100% of the outstanding stock of Chesapeake, a provider of software and services for the process manufacturing supply chain market. The Company expects to exchange approximately 2,950,000 shares of its common stock, valued at approximately $132.8 million, for all the outstanding shares of Chesapeake common stock. The acquisition is expected to be accounted for as a pooling of interests. Accordingly, the consolidated financial statements of the Company will be restated to give retroactive effect to the combination with Chesapeake. The Company expects to incur approximately $5.0 million of expenses related to this acquisition, which will be charged to operations in the quarter in which the acquisition is completed (expect to be the quarter ended June 30, 1998). Unaudited pro forma condensed statements of operations for the nine months ended March 31, 1998 are as follows (in thousands):

5. SHAREHOLDERS' RIGHTS PLAN On October 9, 1997, the Board of Directors voted to adopt a Shareholders' Rights Plan (the Plan). The Plan gives certain shareholders the right to purchase additional shares, at a specified price, under certain circumstances. On March 12, 1998, the Company reincorporated in Delaware. In connection with this reincorporation, the Board of Directors voted to adopt a successor Shareholders' Rights Plan (Successor Plan). The rights of the holders' under the Successor Plan are substantially identical to the rights previously adopted, except the expiration of the Successor Plan has been extended to March 12, 2008. 11 12 ASPEN TECHNOLOGY, INC. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION RESULTS OF OPERATIONS Revenues are derived from software licenses and maintenance and other services. Total revenues for the three and nine months ended March 31, 1998 were $63.7 and $164.5 million, respectively, an increase of 32.8% and 29.5% from $48.0 and $127.0 million in the comparable periods of fiscal 1997. Software license revenues represented 57.9% of total revenues for the three months ended March 31, 1998, as compared to 55.6% in the comparable period of fiscal 1997. Revenues from software licenses for the three and nine months ended March 31, 1998 were $36.9 and $90.1 million, respectively, an increase of 38.4% and 35.1% from $26.7 and $66.7 million in the comparable periods of fiscal 1997. The growth in software license revenues was attributable to software license renewals covering existing users, the expansion of existing customer relationships through licenses covering additional users, additional software products, and, to a lesser extent, to the addition of new customers. Total revenues from customers outside the United States were $29.4 and $78.4 million or 46.1% and 47.7% of total revenues for the three and nine months ended March 31, 1998, respectively, as compared to $19.1 and $64.4 million or 39.8% and 50.7% of total revenues for the comparable periods in fiscal 1997. The geographical mix of license revenues can vary from quarter to quarter; however, for fiscal 1998, the overall mix of revenues from customers outside the United States is expected to be relatively consistent with the prior year. Revenues from maintenance and other services consist of consulting services, post contract support on software licenses, training and sales of documentation. Since the acquisitions of DMCC and Setpoint (January and February 1996), the Company has continued to generate a significant amount of consulting revenues from services for the design, operation and management of process manufacturing plants. As a result, revenues from maintenance and other services for the three and nine months ended March 31, 1998 were $26.8 and $74.4 million, respectively, an increase of 25.8% and 23.2% from $21.3 and $60.3 million in the comparable periods in fiscal 1997. These increases reflect a continued focus during fiscal 1998 on providing high value-added consulting and training services to existing customers. Neither the Company's joint venture and similar activities, nor any discounting or similar activities, have historically had a material effect on the Company's revenues. 12 13 Cost of software licenses consists of royalties, amortization of previously capitalized software costs, costs related to the delivery of software (including disk duplication and third party software costs), printing of manuals and packaging. Cost of software licenses for the three and nine months ended March 31, 1998 was $1.3 and $4.1 million, respectively, an increase of 11.9% and 27.0% from $1.2 and $3.3 million in the comparable periods of fiscal 1997. Cost of software licenses as a percentage of revenues from software licenses was 3.6% and 4.6% for the three and nine months ended March 31, 1998 as compared to 4.4%and 4.9% for the three and nine months ended March 31, 1997. The decline in these costs as a percentage of software license revenue is due to the spreading of fixed costs over a larger revenue base and the decrease in mix of revenue that has variable royalty costs. Cost of maintenance and other services consists of the cost of execution of application consulting services, technical support expenses, the cost of training services and the cost of manuals sold separately. Cost of maintenance and other services for the three and nine months ended March 31, 1998 was $15.4 and $43.1 million, respectively, an increase of 23.5% and 21.1% from $12.5 and $35.6 million in the comparable periods in fiscal year 1997. Cost of maintenance and other services as a percentage of services revenue was 57.4% and 58.0% in the three and nine months ended March 31, 1998 and 58.5% and 59.0% in the comparable period of fiscal year 1997. This percentage decrease reflected improved efficiency in the execution of the implementation services projects. Selling and marketing expenses for the three and nine months ended March 31, 1998 were $19.2 and $50.5 million, an increase of 35.3% and 31.5% from $14.2 and $38.4 million in the comparable periods in fiscal year 1997. As a percentage of revenues, selling and marketing expenses were 30.2% and 30.7%, respectively, for the three and nine months ended March 31, 1998 as compared to 29.6% and 30.3% for the comparable periods in fiscal 1997. The Company continued to invest in sales personnel and regional sales offices to improve the Company's geographic proximity to its customers, to maximize the penetration of existing accounts and to add new customers. Research and development expenses consist primarily of personnel and outside consultancy costs required to conduct the Company's product development efforts. Capitalized research and development costs are amortized over three years. Research and development expenses during the three and nine months ended March 31, 1998 were $10.2 and $29.2 million, respectively, an increase of 29.6% and 33.0% from $7.9 and $22.0 million in the comparable periods of fiscal 1997. The increase in costs reflects continued investment in the development of the Company's core modeling products and a common software architecture encompassing the Company's expanded family of software products. The Company capitalized 8.9% of its total research and development costs during the three months ended March 31, 1998 as compared to 7.4% in the comparable period of fiscal year 1997. 13 14 General and administrative expenses consist primarily of salaries of administrative, executive, financial and legal personnel, outside professional fees, and amortization of certain intangibles. General and administrative expenses for the three and nine months ended March 31, 1998 were $4.9 and $13.6 million, respectively, an increase of 13.5% and 13.4% from $4.3 and $12.0 million in the comparable periods of fiscal 1997. The dollar increase principally reflected the growth in the scale and scope of the Company's operations. In connection with the acquisition of IIsys in March 1998, approximately $8.5 million of the purchase price was allocated to in-process research and development based upon an independent appraisal. These costs were expensed as of the acquisition date (during the quarter ended March 31, 1998) as they relate to projects that had not yet reached technological feasibility and that until completion of development, have no alternative future use. These projects will require substantial additional development and testing by the Company prior to them reaching of technological feasibility. However, there can be no assurance that these projects will reach technological feasibility or develop into products that may be sold profitably by the Company. Interest income is generated from the license of software pursuant to installment contracts for off-line modeling software and the investment of excess cash in short-term and long-term investments. Under these installment contracts, the Company offers customers the option to make annual payments for its term licenses instead of a single license fee payment at the beginning of the license term. A substantial majority of the off-line modeling customers elect to license these products through installment contracts. The Company believes this election is made principally because the customers prefer to pay for the Company's off-line modeling products out of their operating budgets, rather than out of their capital budgets. Included in the annual payments is an implicit interest charge based upon the interest rate established by the Company at the time of the license. The Company sells a portion of the installment contracts to unrelated financial institutions. The interest earned by the Company on the installment contract portfolio in any one year is the result of the implicit interest established by the Company on installment contracts and the size of the contract portfolio. Interest income was $1.4 and $4.1 million for the three and nine months ended March 31, 1998 as compared to $1.2 and $3.8 million for the comparable periods in fiscal 1997. Interest expense is generated from interest charged on the Company's bank line of credit, notes payable and capital lease obligations. Interest expense for the three and nine months ended March 31, 1998 was $0.07 and $0.1 million as compared to $0.03 and $0.1 million in the comparable periods of fiscal year 1997. The effective tax rate decreased for the three and nine months ended March 31, 1998 to 36.0% of pretax income, exclusive of non-recurring charges for in-process research and development from 38.0% for the comparable periods of fiscal 1997. This decrease is primarily due to utilization of various tax credits and carryforwards. 14 15 On April 28, 1998, the Company signed a definitive agreement to acquire 100% of the outstanding common stock of Chesapeake Decision Sciences, Inc. ("Chesapeake") for approximately 2,950,000 shares of common stock. This acquisition, which is expected to be accounted for as a pooling of interests, is expected to close during the quarter ended June 30, 1998. Once complete, the Company's financial statements will be restated to reflect this acquisition, and the comparisons presented herein will then be adjusted to reflect this restatement. LIQUIDITY AND CAPITAL RESOURCES During the nine months ended March 31, 1998, the Company's cash and cash equivalents balance increased by $9.2 million. Operations provided $20.1 million of cash during this period primarily related to net income offset in part by increases in accounts and installments receivable and decreases in accounts payable and accrued expenses. In recent years, the Company has had arrangements to sell long-term contracts to two financial institutions, General Electric Capital Corporation ("GECC") and Sanwa Business Credit Corporation ("SBCC"). During the nine months ended March 31, 1998, installment contracts increased to $51.1 million, net of $44.1 million of installment contracts sold to GECC and SBCC. The Company's arrangements with the two financial institutions provide for the sale of installment contracts up to certain limits and with certain recourse obligations. At March 31, 1998, the balance of the uncollected principal portion of the contracts sold to these two financial institutions was $87.7 million, for which the Company has a partial recourse obligation of approximately $5.0 million. The availability under these arrangements will increase as the financial institutions receive payment on installment contracts previously sold. The Company maintains a $30.0 million bank line of credit, expiring December 31, 1998, that provides for borrowings of specified percentages of eligible accounts receivable and eligible current installment contracts. Advances under the line of credit bear interest at a rate equal to the bank's prime rate (8.5% at March 31, 1998) plus a specified margin or, at the Company's option, a rate equal to a defined LIBOR (5.7% at March 31, 1998) plus a specified margin. The line of credit agreement requires the Company to provide the bank with certain periodic financial reports and to comply with certain financial tests, including maintenance of minimum levels of consolidated net income before taxes and of the ratio of current assets to current liabilities. Management has initiated a Company-wide program to prepare the Company's computer systems and applications as well as the Company's product offerings for the year 2000. The Company expects to incur internal staff costs as well as consulting and other expenses related to system enhancements for the year 2000. A significant number of the Company's product offerings are currently year 2000 compliant. The Company believes the total costs to be incurred for all year 2000 related projects will not have a material impact on the future results from operations. 15 16 ASPEN TECHNOLOGY, INC. PART II. OTHER INFORMATION Item 1. Legal Proceedings The Company is not a party to any pending material proceedings. Item 2. Changes in Securities and Use of Proceeds REINCORPORATION IN DELAWARE On March 12, 1998, Aspen Technology, Inc. a Massachusetts corporation ("Aspen Massachusetts"), changed its state of incorporation from Massachusetts to Delaware by merging with and into Aspen Technology, Inc., a Delaware corporation and a wholly owned subsidiary of Aspen Massachusetts ("Aspen Delaware" or the "Company"). As a result of the reincorporation, each outstanding share of Common Stock, $.10 par value per share, of Aspen Massachusetts ("Aspen Massachusetts Common Stock"), including each associated right under the Rights Agreement (the "Massachusetts Rights Plan") dated as of October 9, 1997 between Aspen Massachusetts and American Stock Transfer and Trust Company, as Rights Agent, changed and converted into one fully paid and non-assessable share of Common Stock, $.10 par value per share, of Aspen Delaware ("Aspen Delaware Common Stock"). In the reincorporation, the Certificate of Incorporation and By-Laws of Aspen Delaware, which were filed as Exhibits 3.1 and 3.2, respectively, to the Company's Current Report on Form 8-K dated March 26, 1998, became the constituent instruments defining the rights of holders of Aspen Delaware Common Stock following the reincorporation. The Company has previously reported, as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended ("Rule 12b-2"), the general effect of the material modifications to the rights of holders of Aspen Massachusetts Common Stock effected by the adoption of the Certificate of Incorporation and By-Laws of Aspen Delaware in its Proxy Statement dated as of November 25, 1997 under the heading "II. Proposal Two--Change in the State of Incorporation from Massachusetts to Delaware--Significant Changes Caused by the Reincorporation." Accordingly, the Company is not making an additional report of that information in this Form 10-Q. For additional information regarding changes in the Certificate of Incorporation of the Company, see "--Stockholder Rights Plan." STOCKHOLDER RIGHTS PLAN As a result of the reincorporation, each right outstanding under the Massachusetts Rights Plan, together with its associated share of Aspen Massachusetts Common Stock, was changed and converted into one share of Aspen Delaware Common Stock. In connection with the reincorporation, on March 12, 1998 the Board of Directors of the Company also issued rights (the "Delaware Rights") substantially equivalent to the rights previously outstanding under the Massachusetts Rights Plan. The Delaware Rights expire on March 12, 2008 unless earlier redeemed by the Company. The description and other terms of the Delaware Rights are set forth in a Rights Agreement (the "Delaware Rights Plan") dated as of March 12, 1998 between the Company and American Stock Transfer and Trust Company, as Rights Agent, filed as Exhibit 4.1 to the Company's Current Report on Form 8-K dated as of March 26, 1998 (including the Form of Certificate of Designation of Series A Participating Cumulative Preferred Stock and the Form of Rights Certificate). In connection with the adoption of the Delaware Rights Plan, the Company amended its Certificate of Incorporation on March 12, 1998 by filing a Certificate of Designation with respect to the Series A Participating Cumulative Preferred Stock issuable upon exercise of the Delaware Rights. The Delaware Rights have certain antitakeover effects and could be deemed to materially limit or qualify the rights of holders of Aspen Delaware Common Stock. The Company has previously reported, as defined in Rule 12b-2, the general effect of the adoption of the Certificate of Designation and the issuance of the Delaware Rights upon the rights of the holders of Aspen Delaware Common Stock under the heading "Item 5. Other Events" in its Current Report on Form 8-K dated as of March 26, 1998. Accordingly, the Company is not making an additional report of that information in this Form 10-Q. 16 17 Item 5.

                                                                   EXHIBIT 3.1A


                           CERTIFICATE OF DESIGNATION
                                       OF
                SERIES A PARTICIPATING CUMULATIVE PREFERRED STOCK


      SECTION 1.  DESIGNATION AND NUMBER OF SHARES

      The shares of this series of Preferred Stock shall be designated as Series
A participating cumulative preferred stock, $.10 par value per share ("Series A
Preferred Stock"). The number of shares initially constituting the Series A
Preferred Stock shall be 400,000; provided, however, that, if more than a total
of 400,000 shares of Series A Preferred Stock shall be issuable upon the
exercise of Rights (the "Rights") issued pursuant to the Rights Agreement dated
as of March 11, 1998, between the Corporation and American Stock Transfer and
Trust Company, a limited power banking trust company licensed by the New York
State Banking Authority, as Rights Agent (the "Rights Agreement"), the board of
directors, pursuant to Section 151(g) of the General Corporation Law of the
State of Delaware, shall direct by resolution or resolutions that a certificate
be properly executed, acknowledged, filed and recorded, in accordance with the
provisions of Section 103 thereof, providing for the total number of shares of
Series A Preferred Stock authorized to be issued to be increased (to the extent
that the Certificate of Incorporation then permits) to the largest number of
whole shares (rounded up to the nearest whole number) issuable upon exercise of
such Rights.

      SECTION 2.  DIVIDENDS OR DISTRIBUTIONS

      (a) Subject to the prior and superior rights of holders of shares of any
other series of Preferred Stock or other class of capital stock of the
Corporation ranking prior and superior to the shares of Series A Preferred Stock
with respect to dividends, holders of Series A Preferred Stock shall be entitled
to receive, when, as and if declared by the board of directors, out of the
assets of the Corporation legally available therefor, (i) quarterly dividends
payable in cash on the last day of each fiscal quarter in each year, or such
other dates as the board of directors of the Corporation shall approve (each
such date being referred to herein as a "Quarterly Dividend Payment Date"),
commencing on the first Quarterly Dividend Payment Date after the first issuance
of a share or a fraction of a share of Series A Preferred Stock, in the amount
of $1.00 per whole share (rounded to the nearest cent) less the amount of all
cash dividends declared on the Series A Preferred Stock pursuant to the
following clause (ii) since the immediately preceding Quarterly Dividend Payment
Date or, with respect to the first Quarterly Dividend Payment Date, since the
first issuance of any share or fraction of a share of Series A Preferred Stock
(the total of which shall not, in any event, be less than zero) and (ii)
dividends payable in cash on the payment date for each cash dividend declared on
the Corporation's common stock, $.10 par value per share ("Common Stock"), in an
amount per whole share (rounded to the nearest cent) equal to the Formula Number
(as hereinafter defined) then in effect times the cash dividends then to be paid
on each share of Common Stock. In addition, if the Corporation shall pay any
dividend or make any distribution on the Common Stock payable in assets,
securities or other forms of noncash consideration (other than dividends or
distributions solely in shares of Common Stock), then, in each such case, the
Corporation shall simultaneously pay or make on each outstanding whole share of
Series A Preferred Stock a dividend or distribution in like kind equal to the
Formula Number then in effect times such dividend or distribution on each share
of the Common Stock. As used herein, the "Formula Number" shall be 100;
provided, however, that if at any time on or after March 13, 1998, the
Corporation shall (i) declare or pay any dividend on the Common Stock payable in
shares of Common Stock or make any

                                       1

   2



distribution on the Common Stock in shares of Common Stock, (ii) subdivide (by a
stock split or otherwise) the outstanding shares of Common Stock into a larger
number of shares of Common Stock or (iii) combine (by a reverse stock split or
otherwise) the outstanding shares of Common Stock into a smaller number of
shares of Common Stock, then in each such event the Formula Number shall be
adjusted to a number determined by multiplying the Formula Number in effect
immediately prior to such event by a fraction, the numerator of which is the
number of shares of Common Stock that are outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
are outstanding immediately prior to such event (and rounding the result to the
nearest whole number); and provided further that, if at any time on or after
March 13, 1998, the Corporation shall issue any shares of its capital stock in a
merger, reclassification, or change of the outstanding shares of Common Stock
then in each such event the Formula Number shall be appropriately adjusted to
reflect such merger, reclassification or change so that each share of Series A
Preferred Stock continues to be the economic equivalent of a Formula Number of
shares of Common Stock prior to such merger, reclassification or change.

      (b) The Corporation shall declare a dividend or distribution on the Series
A Preferred Stock as provided in Section 2(a) immediately prior to or at the
same time it declares a dividend or distribution on the Common Stock (other than
a dividend or distribution solely in shares of Common Stock); provided, however,
that, in the event no dividend or distribution (other than a dividend or
distribution in shares of Common Stock) shall have been declared on the Common
Stock during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the
Series A Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date. The board of directors may fix a record date
for the determination of holders of Series A Preferred Stock entitled to receive
a dividend or distribution declared thereon, which record date shall be the same
as the record date for any corresponding dividend or distribution on Common
Stock.

      (c) Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Preferred Stock from and after the Quarterly Dividend Payment
Date next preceding the date of original issue of such shares of Series A
Preferred Stock; provided, however, that dividends on such shares which are
originally issued after the record date for the determination of holders of
shares of Series A Preferred Stock entitled to receive a quarterly dividend and
on or prior to the next succeeding Quarterly Dividend Payment Date shall begin
to accrue and be cumulative from and after such Quarterly Dividend Payment Date.
Notwithstanding the foregoing, dividends on shares of Series A Preferred Stock
that are originally issued prior to the record date for the determination of
holders of shares of Series A Preferred Stock entitled to receive a quarterly
dividend on the first Quarterly Dividend Payment Date shall be calculated as if
cumulative from and after the last day of the fiscal quarter next preceding the
date of original issuance of such shares. Accrued but unpaid dividends shall not
bear interest. Dividends paid on the shares of Series A Preferred Stock in an
amount less than the total amount of such dividends at the time accrued and
payable on such shares shall be allocated pro rata on a share-by-share basis
among all such shares at the time outstanding.

      (d) So long as any shares of Series A Preferred Stock are outstanding, no
dividends or other distributions shall be declared, paid or distributed, or set
aside for payment or distribution, on Common Stock unless, in each case, the
dividend required by this Section 2 to be declared on Series A Preferred Stock
shall have been declared.

      (e) Holders of Series A Preferred Stock shall not be entitled to receive
any dividends or other distributions except as provided herein.

      SECTION 3.  VOTING RIGHTS

      Holders of Series A Preferred Stock shall have the following voting
rights:

      (a) Each holder of Series A Preferred Stock shall be entitled to a number
of votes equal to the Formula Number then in effect, for each share of Series A
Preferred Stock held of record on each matter on which holders of Common Stock
or stockholders generally are entitled to vote, multiplied by the maximum number
of votes per share which any holder of Common Stock or stockholders generally
then have with respect to such matter (assuming any holding period or other
requirement to vote a greater number of shares is satisfied).

      (b) Except as otherwise provided herein or by applicable law, holders of
Series A Preferred Stock and holders of Common Stock shall vote together as one
class for the election of directors and on all other matters submitted to a vote
of stockholders of the Corporation.

      (c) If, at the time of any annual meeting of stockholders for the election
of directors, the equivalent of six quarterly dividends (whether or not
consecutive) payable on any share or shares of Series A Preferred Stock are in
default, the number of directors constituting the board of directors of the
Corporation shall be increased by two. In addition to voting together with
holders of Common Stock for the election of other directors of the Corporation,
holders of Series A Preferred Stock, voting separately as a class, shall be
entitled at said meeting of stockholders (and at each subsequent annual meeting
of stockholders), unless all dividends in arrears have been paid or declared and
set apart for payment prior thereto, to vote for the election of two directors,
the holders of Series A Preferred Stock being entitled to cast a number of votes
per share of Series A Preferred Stock equal to the Formula Number. Until the
default in payments of all dividends which permitted the election of said
directors shall cease to exist, any director who shall have been so elected
pursuant to the next preceding sentence may be removed at any time, either with
or without cause, only by the affirmative vote of holders of Series A Preferred
Stock at the time entitled to cast a majority of the votes entitled to be cast
for the election of any such director at a special meeting of such holders
called for that purpose, and any vacancy thereby created may be filled by the
vote of such holders. If and when such default shall cease to exist, holders of
Series A Preferred Stock shall be divested of the foregoing special voting
rights, subject to revesting in the event of each and every subsequent like
default in payments of dividends. Upon the termination of the foregoing special
voting rights, the terms of office of all persons who may have been elected
directors pursuant to said special voting rights shall forthwith terminate, and
the number of directors constituting the board of directors shall be reduced by
two. The voting rights granted by this Section 3(c) shall be in addition to any
other voting rights granted to holders of Series A Preferred Stock in this
Section 3.

      (d) Except as provided herein, in Section 11 or by applicable law, holders
of Series A Preferred Stock shall have no special voting rights and their
consent shall not be required (except to the extent they are entitled to vote
with holders of Common Stock as set forth herein) for authorizing or taking any
corporate action.

      SECTION 4.  CERTAIN RESTRICTIONS

      (a) Whenever quarterly dividends or other dividends or distributions
payable on the Series A Preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not declared, on shares of Series A Preferred Stock outstanding shall have
been paid in full, the Corporation shall not


                                       3

   4



            (i) declare or pay dividends on, make any other distributions on, or
      redeem or purchase or otherwise acquire for consideration any shares of
      capital stock ranking junior (either as to dividends or upon liquidation,
      dissolution or winding up) to the Series A Preferred Stock;

            (ii) declare or pay dividends on or make any other distributions on
      any shares of capital stock ranking on a parity (either as to dividends or
      upon liquidation, dissolution or winding up) with the Series A Preferred
      Stock, except dividends paid ratably on the Series A Preferred Stock and
      all such parity capital stock on which dividends are payable or in arrears
      in proportion to the total amounts to which the holders of all such shares
      are then entitled;

            (iii) redeem or purchase or otherwise acquire for consideration
      shares of any capital stock ranking on a parity (either as to dividends or
      upon liquidation, dissolution or winding up) with the Series A Preferred
      Stock; provided that the Corporation may at any time redeem, purchase or
      otherwise acquire shares of any such parity capital stock in exchange for
      shares of any capital stock of the Corporation ranking junior (either as
      to dividends or upon dissolution, liquidation or winding up) to the Series
      A Preferred Stock; or

            (iv) purchase or otherwise acquire for consideration any shares of
      Series A Preferred Stock, or any shares of capital stock ranking on a
      parity with the Series A Preferred Stock, except in accordance with a
      purchase offer made in writing or by publication (as determined by the
      board of directors) to all holders of such shares upon such terms as the
      board of directors, after consideration of the respective annual dividend
      rates and other relative rights and preferences of the respective series
      and classes, shall determine in good faith will result in fair and
      equitable treatment among the respective series or classes.

      (b) The Corporation shall not permit any subsidiary of the Corporation to
purchase or otherwise acquire for consideration any shares of capital stock of
the Corporation unless the Corporation could, under paragraph (a) of this
Section 4, purchase or otherwise acquire such shares at such time and in such
manner.

      SECTION 5.  LIQUIDATION RIGHTS

      Upon the liquidation, dissolution or winding up of the Corporation,
whether voluntary or involuntary, no distribution shall be made (a) to holders
of shares of capital stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock unless,
prior thereto, the holders of Series A Preferred Stock shall have received an
amount equal to the accrued and unpaid dividends and distributions thereon,
whether or not declared, to the date of such payment, plus an amount equal to
the greater of (i) $10.00 per whole share and (ii) an aggregate amount per share
equal to the Formula Number then in effect multiplied by the aggregate amount to
be distributed per share to holders of Common Stock or (ii) to the holders of
capital stock ranking on a parity (either as to dividends or upon liquidation,
dissolution or winding up) with the Series A Preferred Stock, except
distributions made ratably on the Series A Preferred Stock and all other such
parity capital stock in proportion to the total amounts to which the holders of
all such shares are entitled upon such liquidation, dissolution or winding up.

      SECTION 6.  CONSOLIDATION, MERGER, ETC.

      In case the Corporation shall enter into any consolidation, merger,
combination or other transaction in which shares of Common Stock are exchanged
for or changed into other capital stock or securities, cash or any other
property, then in any such case the then-outstanding shares of Series A
Preferred Stock shall at the same time be similarly exchanged or changed into an
amount per share equal to the Formula Number then in effect multiplied by the
aggregate amount of capital stock, securities, cash or any other property
(payable

                                       4

   5



in kind), as the case may be, into which or for which each share of Common Stock
is exchanged or changed. In the event both Section 2 and this Section 6 would
apply to a transaction, this Section 6 shall control.

      SECTION 7.  NO REDEMPTION; NO SINKING FUND

      (a) Series A Preferred Stock shall not be subject to redemption by the
Corporation or at the option of any holder of Series A Preferred Stock;
provided, however, that the Corporation may purchase or otherwise acquire
outstanding shares of Series A Preferred Stock in the open market or by offer to
any holder or holders of Series A Preferred Stock.

      (b) Series A Preferred Stock shall not be subject to or entitled to the
operation of a retirement or sinking fund.

      SECTION 8.  RANKING

      Series A Preferred Stock shall rank junior to all other series of
Preferred Stock of the Corporation, unless the board of directors shall
specifically determine otherwise in fixing the powers, preferences and relative,
participating, optional and other special rights of the shares of such series
and the qualifications, limitations and restrictions thereof.

      SECTION 9.  FRACTIONAL SHARES

      Series A Preferred Stock shall be issuable upon exercise of the Rights
issued pursuant to the Rights Agreement in whole shares or in any fraction of a
share that is one one-hundredth (1/100th) of a share or any integral multiple of
such fraction that shall entitle the holder, in proportion to such holder's
fractional shares, to receive dividends, exercise voting rights, participate in
distributions and to have the benefit of all other rights of holders of Series A
Preferred Stock. In lieu of fractional shares, the Corporation, prior to the
first issuance of a share or a fraction of a share of Series A Preferred Stock,
may elect (a) to make a cash payment as provided in the Rights Agreement for
fractions of a share other than one one-hundredth (1/100th) of a share or any
integral multiple thereof or (b) to issue depository receipts evidencing such
authorized fraction of a share of Series A Preferred Stock pursuant to an
appropriate agreement between the Corporation and a depository selected by the
Corporation; provided that such agreement shall provide that the holders of such
depository receipts shall have all the rights, privileges and preferences to
which they are entitled as holders of the Series A Preferred Stock.

      SECTION 10.  REACQUIRED SHARES

      Any shares of Series A Preferred Stock purchased or otherwise acquired by
the Corporation in any manner whatsoever shall be retired and canceled promptly
after the acquisition thereof. All such shares shall upon their cancellation
become authorized but unissued shares of Preferred Stock, without designation as
to series until such shares are once more designated as part of a particular
series by the board of directors pursuant to the provisions of Section (b) of
Article FOURTH of the Certificate of Incorporation.

      SECTION 11.  AMENDMENT

      None of the powers, preferences and relative, participating, optional and
other special rights of the Series A Preferred Stock as provided herein or
otherwise in the Certificate of Incorporation shall be amended in any manner
that would alter or change the powers, preferences, rights or privileges of the
holders of Series A Preferred Stock so as to affect them adversely without the
affirmative vote of the holders of at least

                                       5

   6



66 2/3% of the outstanding shares of Series A Preferred Stock, voting as a
separate class; provided, however, that no such amendment approved by the
holders of at least 66 2/3% of the outstanding shares of Series A Preferred
Stock shall be deemed to apply to the powers, preferences, rights or privileges
of any holder of Series A Preferred Stock originally issued upon exercise of the
Rights after the time of such approval without the approval of such holder.

      IN WITNESS WHEREOF, Aspen Technology, Inc. has caused this Certificate of
Designation of Series A Participating Cumulative Preferred Stock to be executed
on its behalf by its President and its Secretary as of March 12, 1998.

                             ASPEN TECHNOLOGY, INC.


      This certifies that               , or registered assigns, is the 
registered owner of the number of Rights set forth above, each of which 
entitles the owner, thereof, subject to the terms, provisions and conditions of
the Rights Agreement dated as of March 12, 1998 (the "Rights Agreement"), 
between Aspen Technology, Inc., a Delaware corporation (the "Company"), and 
American Stock Transfer and Trust Company, a limited power banking trust 
company licensed by the New York State Banking Authority, as Rights Agent (the 
"Rights Agent"), unless the Rights evidenced hereby shall have been previously 
redeemed by the Company, to purchase from the Company at any time after the 
Distribution Date (as defined in the Rights Agreement) and prior to 5:00 p.m., 
Boston time, on the tenth anniversary of the date of the Rights Agreement (the 
"Expiration Date"), at the office of the Rights Agent, or its successors as 
Rights Agent, in Brooklyn, New York, one one-hundredth (1/100th) of a fully 
paid, nonassessable share of Series A Participating Cumulative Preferred Stock,

purchase price per one one-hundredth (1/100th) of a share equal to $175.00 (the
 "Purchase Price") payable in cash, upon presentation and surrender of this 
Right Certificate with the Form of Election to Purchase duly executed.

      The Purchase Price and the number and kind of shares which may be
purchased upon exercise of each Right evidenced by this Right Certificate, as
set forth above, are the Purchase Price and the number and kind of shares which
may be so purchased as of March 12, 1998. As provided in the Rights Agreement,
the Purchase Price and the number and kind of shares which may be purchased upon
the exercise of each Right evidenced by this Right Certificate are subject to
modification and adjustment upon the happening of certain events.

      If the Rights evidenced by this Right Certificate are at any time
beneficially owned by an Acquiring Person or an Affiliate or Associate of an
Acquiring Person (as such terms are defined in the Rights Agreement), such
Rights shall be null and void and nontransferable and the holder of any such
Right (including any purported transferee or subsequent holder) shall not have
any right to exercise or transfer any such Right.

      This Right Certificate is subject to all the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
reference to the Rights Agreement is hereby made for a full description of the

of rights, obligations, duties and immunities hereunder of the Rights Agent, the
Company and the holders of the Right Certificates. Copies of the Rights
Agreement are on file at the above-mentioned office of the Rights Agent and are
also available from the Company upon written request.

      This Right Certificate, with or without other Right Certificates, upon
surrender at the stock transfer or corporate trust office of the Rights Agent,
may be exchanged for another Right Certificate or Right Certificates of like
tenor and date evidencing Rights entitling the holder to purchase a like
aggregate number and kind of shares as the Rights evidenced by the Right
Certificate or Right Certificates surrendered shall entitle such holder to
purchase. If this Right Certificate shall be exercised in part, the holder shall
be entitled to receive upon surrender hereof another Right Certificate or Right
Certificates for the number of whole Rights not exercised.

      Subject to the provisions of the Rights Agreement, the Rights evidenced by
this Right Certificate may be redeemed by the Company at its option at a
redemption price (in cash or shares of Common Stock or other securities of the
Company deemed by the Board of Directors to be at least equivalent in value) of
$.01 per Right (which amount shall be subject to adjustment as provided in the
Rights Agreement) at any time prior to the earlier of (i) such time as a Person
becomes an Acquiring Person and (ii) the Expiration Date.

      The Company may, but shall not be required to, issue fractions of
Preferred Shares or distribute certificates which evidence fractions of
Preferred Shares upon the exercise of any Right or Rights evidenced hereby. In
lieu of issuing fractional shares, the Company may elect to make a cash payment
as provided in the Rights Agreement for fractions of a share other than one
one-hundredth (1/100th) of a share or any integral multiple thereof or to issue
certificates or utilize a depository arrangement as provided in the terms of the
Rights Agreement and the Preferred Shares.

      No holder of this Right Certificate shall be entitled to vote or receive
dividends or be deemed for any purpose the holder of the Preferred Shares or of
any other securities of the Company which may at any time be issuable on the
exercise hereof, nor shall anything contained in the Rights Agreement or herein
be construed to confer upon the holder hereof, as such, any of the rights of a
stockholder of the Company, including, without limitation, any right to vote for
the election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting stockholders (except as
provided in the Rights Agreement), or to receive dividends or other
distributions or subscription rights, or otherwise, until the Right or Rights
evidenced by this Right Certificate shall have been exercised as provided in
accordance with the provisions of the Rights Agreement.

      This Right Certificate shall not be valid or obligatory for any purpose
until it shall have been counter signed by the Rights Agent.
