ITEM 4. DESCRIPTION OF SECURITIES. Not applicable. ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL. The validity of the securities registered hereby is being passed upon for the Company by Foley, Hoag & Eliot LLP, Boston, Massachusetts. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS. Article 6 of the Company's Restated Articles of Organization eliminates the personal liability of a director to the Company or its stockholders for monetary damages arising out of such director's breach of fiduciary duty as a director of the Company to the maximum extent permitted by Massachusetts law. Section 13(b)(1-1/2) of Chapter 156B of the Massachusetts Business Corporation Law provides that the articles of organization of a corporation may state a provision eliminating the personal liability of a director to a corporation or its stockholders for monetary damages for breach of fiduciary duty as a director; provided, however, that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts of commission not in good faith or which involve intentional misconduct or knowing violation of law, (iii) under section 61 or 62 of the Massachusetts Business Corporation Law

3 dealing with liability for unauthorized distributions and loans to insiders, respectively, or (iv) for any transaction from which the director derived an improper personal benefit. Article VII of the Company's By-Laws provides that the Company shall indemnify its officers and directors, and directors, officers, trustees, employees and other agents of any organization in which the Company owns shares or of which it is a creditor, against all liabilities and expenses reasonably incurred by such officers, directors, employees and other agents in connection with the defense or disposition of any action, suit or proceeding in which they may be involved by reason of having been a director, officer of employee or other agent, except with respect to any matter as to which they shall have been adjudicated not to have acted in good faith and reasonably believe that their action was in the best interests of the Company. Section 67 of the Massachusetts Business Corporation Law authorizes a corporation to indemnify its directors, officers, employees and other agents unless such person shall have been adjudicated in any proceeding not to have acted in good faith in the reasonable belief that such action was in the best interests of the corporation. The effect of these provisions would be to permit such indemnification by the Company for liabilities arising out of the Securities Act of 1933, as amended. The Company also maintains an officers and directors liability insurance policy. ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED. Not applicable. ITEM 8.

UNDERTAKINGS. 1. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 2. The undersigned registrant hereby undertakes that, (a) To file, during any period in which offers or sales are being made, a post-effective

4 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; PROVIDED, HOWEVER, that paragraphs (a)(i) and (a)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Registration Statement. (b) 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 herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) 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. 3. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

1 EXHIBIT 4.1 PROGRESS SOFTWARE CORPORATION 1991 EMPLOYEE STOCK PURCHASE PLAN (Amended and Restated as of March 10, 1998) 1. PURPOSE The Progress Software Corporation Employee Stock Purchase Plan (the "Plan") is intended to provide a method whereby employees of Progress Software Corporation (the "Company") will have an opportunity to acquire an ownership interest (or increase an existing ownership interest) in the Company through the purchase of shares of the Common Stock of the Company. It is the intention of the Company that the Plan qualify as an "employee stock purchase plan" under Section 423 of the Internal Revenue Code of 1986, as amended (the "Code"). The provisions of the Plan shall, accordingly, be construed so as to extend and limit participation in a manner consistent with the requirements of that section of the Code. 2. DEFINITIONS (a) "Eligible Compensation" for purposes of the Plan means: (i) with respect to individuals who are hourly employees, base salary plus payments for overtime and bonuses or (ii) with respect to individuals who are salaried employees, base salary plus sales commissions and bonuses. Eligible Compensation shall not include any deferred compensation other than contributions by an individual through a salary reduction agreement to a cash or deferred plan pursuant to Section 401(k) of the Code or to a cafeteria plan pursuant to Section 125 of the Code. (b) "Board" means the Board of Directors of the Company. (c) "Committee" means the Compensation Committee of the Board. (d) "Common Stock" means the common stock, $.01 par value per share, of the Company. (e) "Company" shall also include any subsidiary of Progress Software Corporation designated as a participant in the Plan by the Board, unless the context otherwise requires. (f) "Employee" means any person who is customarily employed at least 20 hours per week and more than five months in a calendar year by (i) the Company or (ii) any subsidiary corporation. (g) "Subsidiary Corporation" shall mean any present or future corporation which is or would constitute a "subsidiary corporation" as that term is defined in Section 424(f) of the Code. 3. ELIGIBILITY (a) Participation in the Plan is completely voluntary. Participation during any one or more of the Offering Periods, as hereafter defined, under the Plan shall neither limit, nor require, participation during any other Offering Period. (b) Each Employee of the Company and its Subsidiary Corporations shall be eligible to participate in the Plan on any Offering Period commencement date, as hereafter identified, following the completion of three months of continuous service with the Company and/or its Subsidiary Corporations; provided, however, that no Employee shall be granted an option under the Plan:

2 (i) if, immediately after the grant, such Employee would own stock, and/or hold outstanding options to purchase stock, possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or any Subsidiary Corporation; for purposes of this Paragraph the rules of Section 424(d) of the Code shall apply in determining stock ownership of any employee; or (ii) which permits his/her rights to purchase stock under all Section 423 employee stock purchase plans of the Company and its Subsidiary Corporations to exceed US $25,000 of the fair market value of the stock (determined at the time such option is granted) for each calendar year in which such option is outstanding; for purposes of this Paragraph, the rules of Section 423 (b)(8) of the Code shall apply. 4. OFFERING PERIOD / EXERCISE PERIOD The right to purchase stock hereunder shall be made available by a series of "Exercise Periods" during an "Offering Period" to employees eligible in accordance with Paragraph 3 hereof. Offering Period. Each participant in the Plan will be enrolled in an Offering Period. An Offering Period has a duration of 27 consecutive months unless a participant: withdraws from the Plan, ceases to be an eligible employee, or is automatically transferred to a new Offering Period. Offering Periods commence on each of the following dates: January 1, April 1, July 1, or October 1. Exercise Period. Each 27-month Offering Period consists of nine consecutive Exercise Periods lasting three months each. Exercise Periods start on January 1, April 1, July 1, and October 1. Exercise Date. During each 27-month Offering Period there will be nine Exercise Dates. An Exercise Date is the last date of each Exercise Period. Therefore, Exercise Dates will be as follows: March 31, June 30, September 30, and December 31. 5. PARTICIPATION Any eligible employee may become a participant by completing a payroll deduction authorization form provided by the Company and filing it with their payroll department and the Plan administrator 20 days prior to an Offering Period commencement date. A participant may be enrolled in only one Offering Period at a time. A participant will be re-enrolled automatically as a participant in future Offering Periods when an Offering Period in which such participant is currently enrolled ends, unless such participant withdraws from participation, is terminated or terminates employment, becomes ineligible to participate for any reason, or the Plan terminates. 6. PAYROLL DEDUCTIONS (a) At the time a participant files his/her authorization for a payroll deduction, he/she shall specify a percentage of his/her Eligible Compensation to be deducted from his/her pay on each payday during any Offering Period in which he/she is a participant in the Plan. Such percentage shall be in increments of one percent (1%) up to a maximum percentage to be established for each Offering Period by the Committee. (b) Payroll deductions for participants shall commence on the Offering Period commencement date following the effective date of his/her authorization for such payroll deductions. (c) A participant may, at any time, reduce the percentage (but not below 1%) of his/her Eligible Compensation to be deducted on each payday that he/she participates in the Plan. A reduction in

3 payroll deductions will be effective on the seventh business day following receipt of notice by the Company and will apply to the first full pay period commencing after such date. (d) A participant may, at any time, increase the percentage (but not above the maximum established by the Committee) of his/her Eligible Compensation to be deducted on each payday that the he/she participates in the Plan. An increase in payroll deductions will be effective on the seventh business day following receipt of notice by the Company and will apply to the first full Exercise Period commencing after such date. (e) All payroll deductions made for a participant shall be credited to his/her account under the Plan. A participant may not make any separate cash payment into such account. 7. GRANTING OF OPTION / EXERCISE PRICE (a) On the commencement date of each Offering Period, a participant in such Offering Period shall be deemed to have been granted an option to purchase on each Exercise Date during such Offering Period (at the per share exercise price) up to a number of shares of the Company's Common Stock determined by dividing such participant's payroll deductions accumulated during the applicable Exercise Period by eighty-five (85%) of the market value per share of the Company's Common Stock on the Offering Period commencement date or on the Exercise Date, whichever is lower, provided that the number of shares subject to the option shall not exceed 200% of the number of shares determined by dividing 10% of the participant's Eligible Compensation over the Offering Period (determined as of the Offering Period commencement date) by 85% of the market value per share of the Company's Common Stock on the Offering Period commencement date, subject to the limitations set forth in Section 3 (b) and 12 hereof. The Market value per share of the Company's Common Stock shall be determined as provided in Section 7(b) herein. (b) The exercise price per share to be paid for Common Stock purchased under the Plan shall be equal to the lower of 85% of the market value per share of the Common Stock on the first day of the Offering Period in which the Exercise Date falls, or 85% of the market value per share of the Common Stock on the Exercise Date. Market value per share of the Common Stock on a particular date is the closing price (or closing bid, if no sales were reported) of the Common Stock on the National Association of Securities Dealers Automated Quotation System, Inc. ("NASDAQ"), or, in the event the Common Stock is listed on a stock exchange, the market value per share shall be the closing price on such exchange, for that date, as reported in the Wall Street Journal. If a closing price is not available for a particular date, then the market value per share to be used for that date will be the closing stock price as of the last preceding trading day on the NASDAQ or a stock exchange for which a closing price is available. If the Common Stock is not listed on the NASDAQ or a stock exchange then the market value per share will be determined by the Committee. For purpose of calculating the number of shares of Common Stock to be purchased with payroll deductions from participants outside of the United States, the Company will use the exchange rate published in the Wall Street Journal on the Exercise Date. 8. EXERCISE OF OPTION Unless a participant withdraws from the Plan or is terminated from participating in the Plan pursuant to paragraph 10 hereof, his/her option for the purchase of Common Stock will be deemed to have been exercised automatically on each Exercise Date for the purchase of the number of full shares of Common Stock which the accumulated payroll deductions in his/her account at that time will purchase at the price of the Common Stock as determined in Paragraph 7 (b). Fractional shares will not be issued under the Plan and any excess funds in a participant's account representing any fractional shares after Common Stock

4 purchases made on each Exercise Date will be automatically carried forward to the next Exercise Period unless the participant elects, by written notice to their payroll department, to have the excess returned to him/her. 9. NEW OFFERING PERIOD If the market value of the Common Stock is lower on an Exercise Date than it was on the first day of the Offering Period, then all participants in such Offering Period will be automatically withdrawn from that Offering Period immediately after the participants' exercise of the option on such Exercise Date, and such participants will be automatically re-enrolled in a new Offering Period commencing immediately after that Exercise Date. The old Offering Period terminates upon such automatic re-enrollment. 10. WITHDRAWAL AND TERMINATION (a) Prior to the Exercise Date for each Exercise Period, any participant may withdraw all but not less than all of his/her payroll deductions under the Plan for such Exercise Period by giving written notice to his/her payroll department. All of the participant's payroll deductions credited to such account will be paid to him/her after receipt of notice of withdrawal, without interest, and no future payroll deductions will be made. Withdrawal from an Exercise Period will be deemed to be a withdrawal from the Offering Period which includes such Exercise Period. The Company will treat any attempt to borrow by a participant on the security of accumulated payroll deductions as an election to withdraw such deductions. (b) A participant may elect not to exercise an option by giving written notice to their payroll department no less than seven (7) business days prior to the applicable Exercise Date. Any such election will be treated as a withdrawal pursuant to section (a) above. (c) A participant's election not to participate in, or withdrawal from, any Offering Period or Exercise Period within such Offering Period will not have any effect upon his/her eligibility to participate in any succeeding Offering Period or in any similar plan which may hereafter be adopted by the Company. (d) Upon termination of the participant's employment for any reason, including retirement but excluding death, all of his/her payroll deductions accrued during the relevant Exercise Period will be returned to the participant. (e) Upon termination of the participant's employment because of death, the participant's beneficiary (as defined in Paragraph 14) shall have the right to elect, by written notice given to the participant's former payroll department prior to the expiration of a period of 90 days commencing with the date of the death of the participant but in no event later than the applicable Offering Period, either (i) to withdraw all of the payroll deductions credited to the participant's account under the Plan; or (ii) to exercise the participant's option for the purchase of stock on the Exercise Date next following the date of the participant's death for the purchase of the number of full shares which the participant's accumulated payroll deductions, at the date of the participant's death, will purchase at the applicable price, and any excess deductions will be returned to said beneficiary. In the event that no such written notice of election shall be duly received by the appropriate payroll department of the Company, the beneficiary shall automatically be deemed to have elected to withdraw the payroll deductions credited to the participant at the date of the participant's death and the same will be paid promptly to said beneficiary.

5 11. INTEREST No interest will be paid or allowed on any money paid into the Plan or credited to any participant. 12. STOCK (a) The maximum number of shares of Common Stock available for issuance and purchase by participants under the Plan, subject to adjustment upon changes in capitalization of the Company as provided in Paragraph 17, shall be 500,000 shares of Common Stock, par value $.01 per share, of the Company. If on a given Exercise Date the number of shares with respect to which options are to be exercised exceeds the number of shares then available, the Company shall make a pro rata allocation of the shares available for delivery and distribution in an equitable manner, with the balances of payroll deductions credited to each participant under the Plan carried forward to the next Exercise Period in the applicable Offering Period or returned to the participant if the participant so chooses, by giving written notice to their payroll department to this effect. (b) The participant will have no interest in stock underlying his/her option until such option has been exercised. (c) The Committee, in its sole discretion, may establish a minimum holding period, if any, for shares of stock acquired pursuant hereto by any participant or his beneficiary pursuant to Paragraph 14 hereof. Certificates representing said shares of stock issued pursuant to this Plan may bear legends to that effect. 13. ADMINISTRATION The Plan shall be administered by the Committee. The interpretation and construction of any provision of the Plan and adoption of rules and regulations for administering the Plan shall be made by the Committee. Determinations made by the Committee with respect to any matter or provision contained in the Plan shall be final, conclusive and binding upon the Company and upon all participants, their heirs or legal representatives. Any rule or regulation adopted by the Committee shall remain in full force and effect unless and until altered, amended, or repealed by the Committee. 14. DESIGNATION OF BENEFICIARY A participant shall file with their payroll department a written designation of a beneficiary who is to receive any Common Stock and/or cash under the Plan. Such designation of beneficiary may be changed by the participant at any time by written notice. Upon the death of a participant and upon receipt by the Company of proof of the identity and existence at the participant's death of a beneficiary validly designated by him under the Plan, the Company shall deliver such Common Stock and/or cash to such beneficiary validly designated under the Plan who is living at the time of such participant's death, the Company shall deliver such Common Stock and/or cash to the executor or administrator of the estate of the participant. No beneficiary shall prior to the death of the participant by whom he has been designated, acquire any interest in the Common Stock and/or cash credited to the participant under the Plan. 15. TRANSFERABILITY Neither payroll deductions credited to a participant nor any rights with regard to the exercise of an option or to receive Common Stock under the Plan may be assigned, transferred, pledged, or otherwise disposed of in any way by the participant other than by will or the laws of descent and distribution. Any such attempted assignment, transfer, pledge, or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw funds in accordance with Paragraph 10(a).

6 16. USE OF FUNDS All payroll deductions received or held by the Company under this Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions. 17. EFFECT OF CHANGES OF COMMON STOCK If the Company shall subdivide or reclassify the Common Stock which has been or may be optioned under this Plan, or shall declare thereon any dividend payable in shares of such Common Stock, or shall take any other action of a similar nature affecting such Common Stock, then the number and class of shares of Common Stock which may thereafter be optioned (in the aggregate and to any participant) shall be adjusted accordingly and in the case of each option outstanding at the time of any such action, the number and class of shares which may thereafter be purchased pursuant to such option and the option price per share shall be adjusted to such extent as may be determined by the Committee, with the approval of independent public accountants and counsel, to be necessary to preserve the rights of the holder of such option. 18. AMENDMENT OR TERMINATION The Board may at any time terminate or amend the Plan. No such termination shall affect options previously granted, nor may an amendment make any change in any option theretofore granted which would adversely affect the rights of any participant holding options under the Plan. 19. NOTICES All notices or other communications by a participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received by the participant's payroll department. 20. MERGER OR CONSOLIDATION If the Company shall at any time merge into or consolidate with another corporation, the holder of each option then outstanding will thereafter be entitled to receive at the next Exercise Date upon the exercise of such option for each share as to which such option shall be exercised, the securities or property which a holder of one share of the Common Stock was entitled to upon and at the time of such merger or consolidation. In accordance with this Paragraph and Paragraph 17, the Committee shall determine the kind and amount of such securities or property which such holder of an option shall be entitled to receive. A sale of all or substantially all of the assets of the Company shall be deemed a merger or consolidation for the foregoing purposes. 21. APPROVAL OF STOCKHOLDERS The Plan is subject to the approval of the stockholders of the Company at their next annual meeting or at any special meeting of the stockholders for which one of the purposes of such a special meeting shall be to act upon the Plan. 22. GOVERNMENTAL AND OTHER REGULATIONS The Plan, and the grant and exercise of the rights to purchase shares hereunder, and the Company's obligation to sell and deliver shares upon the exercise of rights to purchase shares, shall be subject to all applicable federal, state and foreign laws, rules and regulations, and to such approvals by any regulatory or governmental agency as may, in the opinion of counsel for the Company, be required. The Plan shall be governed by, and construed and enforced in accordance with, the provisions of Sections 421, 423 and 424

7 of the Code and the substantive laws of the Commonwealth of Massachusetts. In the event of any inconsistency between such provisions of the Code and any such laws, said provisions of the Code shall govern to the extent necessary to preserve favorable federal income tax treatment afforded employee stock purchase plans under Section 423 of the Code.
