DIRECTORS' FEES Directors who are not also Officers of the Company are currently being paid an annual Director's fee of $35,000 plus $1,250 for attendance at each Board of Directors meeting, Audit Committee meeting and Compensation and Development Committee meeting. No such fees are paid to Directors who are also Officers of the Company. Under the Company's 1965 Directors' Deferred Compensation Plan, the Company has entered into agreements with certain of its non-employee Directors under which a Director, at his election, may defer receipt of his Director's fees and such deferred fees are (i) used to purchase shares of the Company's Common Stock and such shares and future distributions thereon are deposited in the Director's account, (ii) credited to the Stepan Company Deferred Income Account, (iii) used to purchase shares of selected publicly- traded mutual funds or (iv) divided equally between the purchase of shares of the Company's Common Stock, the Stepan Company Deferred Income Account and shares of selected publicly traded mutual funds. Funds in the Stepan Company Deferred Income Account may not be used to purchase shares of the Company's Common Stock, but earn interest at the same rate as bonds with a maturity of ten years. At the election of a Director, deferred payments may be made in shares of Stepan Common Stock or cash based on the fair market value of the Director's account at distribution, which commences, depending upon the terms of the agreement with the particular Director, upon retirement as a Director or from active or professional life or at any time between ages 60 to 70, with payments being made periodically over a period of five to ten years. In addition, the 1992 Stock Option Plan provides for the granting of a stock option, as of the date of the annual meeting of the Company's stockholders in calendar year 2000 to each non-employee Director serving as a Director of the Company on such date to purchase the number of shares of Common Stock determined by dividing the non-employee Director's annual retainer fee for the applicable year by the fair market value of a share of Common Stock on the date of the grant. The exercise price of each share of Common Stock under a stock option granted to a non-employee Director will be equal to the fair market value of a share of Common Stock on the date of the grant or, if greater, par value. The exercise price may be paid, upon exercise, in cash, in shares of Common Stock or in any combination of cash or Common Stock as the non-employee Director completes two continuous years of service as a non-employee Director following the date of the grant, but not more than ten years after the date of the grant. The 1992 Stock Option Plan sets forth restrictions upon the exercise of stock options by non-employee Directors upon termination of their service by reason of death, disability, retirement or otherwise. The Company has a non-qualified, non-funded retirement income plan for the benefit of the non-employee Directors. The plan provides for a benefit after ten years of service of 50 percent of the annual Director's fee at retirement plus two percent for each year served on the Board in excess of ten years with a maximum 25 years credit in excess of ten years. Benefits commence at 70 years of age. RETIREMENT PLANS The Company has a non-contributory retirement plan (the "Retirement Plan") covering all salaried employees that provides for a maximum pension benefit equal to 50 percent of the employee's average base compensation, reduced by an amount equal to 50 percent of the employee's primary Social Security benefit at age 65, for employees with 30 years of service who retire at or after age 63. Base compensation is computed on the average base salary for the five highest consecutive earnings years during the last 15 years prior to retirement. The amount of salary taken into account for any year is subject to certain limitations contained in the Internal Revenue Code ($160,000 in 1998, to be indexed in future years for inflation in accordance with IRS regulations, and subject to certain transition rules for prior years in which greater amounts of salary were permitted to be taken into account). The Company also has a nonqualified supplemental retirement plan (the "SERP") for designated executives. The SERP replaces benefits under the qualified plan that would otherwise be denied due to Internal Revenue Code limits on qualified plan benefits. The following table sets forth the maximum annual retirement income payable under the Retirement Plan and the SERP, prior to reduction by an amount equal to 50 percent of projected age 65 Social Security benefits, at age 63 for indicated salaries and lengths of service. 9

PROPOSAL TO AMEND THE COMPANY'S CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES The present capital structure of the Company authorizes 15,000,000 shares of Common Stock, par value $1 per share. The Board of Directors believes this capital structure is inadequate for the present and future needs of the Company. Therefore, the Board of Directors has unanimously approved the amendment and restatement of the Company's Fourth Article of its Certificate of Incorporation (the "Certificate") to increase the authorized number of shares of Common Stock from 15,000,000 shares to 30,000,000 shares. The Board believes this capital structure more appropriately reflects the present and future needs of the Company and recommends such amendment and restatement to the Company's shareholders for adoption. On March 12, 1999, shares of Common Stock were outstanding ( shares assuming conversion of all of the Preferred Stock) and shares of Preferred Stock were outstanding. In addition, 1,600,000 shares have been reserved for issuance under the 1992 Stock Option Plan. Purpose of Authorizing Additional Common Stock Authorizing an additional 15,000,000 shares of Common Stock would give the Board of Directors the express authority, without further action of the shareholders, to issue such Common Stock from time to time as the Board of Directors deems necessary. The Board of Directors believes it is necessary to have the ability to issue such additional shares of Common Stock for general corporate purposes. Potential uses of the additional authorized shares may include acquisition transactions, equity financings, stock dividends or distributions, and issuance of options pursuant to the Company's 1992 Stock Option Plan without further action by the shareholders, unless such action were specifically required by applicable law or rules of any stock exchange on which the Company's securities may then be listed. The proposed increase in the authorized number of shares of Common Stock could have a number of effects on the Company's shareholders depending upon the exact nature and circumstances of any actual issuance of authorized but unissued shares. While the Company has no present intention of issuing shares for such purposes, the increase could have an anti-takeover effect, in that additional shares could be issued (within the limits imposed by applicable law) in one or more transactions that could make a change in control or takeover of the Company more difficult. For example, additional shares could be issued by the Company so as to dilute the stock ownership or voting rights of persons seeking to obtain control of the Company. Similarly, the issuance of additional shares to certain persons allied with the Company's management could have the effect of making it more difficult to remove the Company's current management by diluting the stock ownership or voting rights of persons seeking to cause such removal. In addition, an issuance of additional shares by the Company could have an effect on the potential realizable value of a shareholder's investment. In the absence of a proportionate increase in the Company's earnings and book value, an increase in the aggregate number of outstanding shares of the Company caused by the issuance of the additional shares would dilute the earnings per share and book value per share of all outstanding shares of the Company's Common Stock. If such factors were reflected in the price per share of Common Stock, the potential realizable value of the shareholder's investment could be adversely affected. The Common Stock carries no preemptive rights to purchase additional shares. The proposed amendment and restatement of the Company's Certificate was approved by a vote of the Board of Directors of the Company on February 16, 1999. The Proposal The first paragraph of the Fourth Article of the Company's Certificate of Incorporation would be amended to provide as follows: FOURTH. The total number of shares of stock which the corporation shall have authority to issue is Thirty Two Million (32,000,000) shares, of which Thirty Million (30,000,000) shares shall be Common Stock of a par value of $1.00 per share, and Two Million (2,000,000) shares shall be Preferred Stock without par value. 12

Vote The affirmative vote of at least a majority of the votes which all stockholders are entitled to cast at the meeting is required for adoption of the Certificate amendment. THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE AMENDMENT TO THE COMPANY'S CERTIFICATE OF INCORPORATION. ---------------- REPORT OF THE COMPENSATION AND DEVELOPMENT COMMITTEE The Company's executive compensation program is administered by the Compensation and Development Committee of the Board of Directors, which is composed of the following non-employee Directors: Messrs. Cadieux, Grojean, Potter and P. Stepan. During 1998, Mr. Grojean served as Chairman for the Committee. All issues pertaining to corporate officer compensation are submitted to the Committee for approval prior to implementation. Non-officer compensation for those reporting to the Chief Executive Officer is reviewed by the Committee as requested. The Company's guiding philosophy in executive compensation is that: a) The base pay of executive officers should reflect job responsibilities and performance, and should be competitive internally to the like or comparable positions as well as being competitive externally to the like or comparable positions within the chemical industry. To this end, the Company uses job evaluation and measurement techniques consistent with modern industrial practice and sets pay policy in accordance with data supplied by Hay Associates, an independent compensation consulting firm, for base pay trends in the chemical industry. Within individual salary ranges, base salary levels for each executive officer are determined in accordance with performance standards set by Company policy, and in compliance with position in the salary range and the merit increase guidelines published annually for all salaried employees. A separate determination is made where an executive officer is promoted or assumes additional responsibilities which may result in an increase in excess of the merit increase guideline. During 1998, merit increases for executive officers slightly exceeded the Company's merit guideline and averaged 6.6%. One corporate officer received a promotional increase approximating 18.9%. The Chairman, President and Chief Executive Officer's (CEO) salary range is determined by the same process and procedures as those of other executive officers. The CEO's salary is adjusted by the Committee in accordance with the salary merit increase guideline. During 1998, the CEO's base earnings increased by 4.0% over the prior year. (b) The incentive pay of executive officers should be tied directly to the performance of the Company and to the performance of the individual executive against a set of individual performance targets in a given calendar year. In years where the Company performs well against its economic targets, significant performance bonuses may be earned; if targets are not achieved or exceeded, incentive bonuses are proportionately lower or may not be paid at all. All executive officers have a minimum of 25% of their incentive bonus based on the performance of the Company overall measured against targets for (a) Net Income and (b) Return on Invested Capital approved by the Committee for each calendar year period. The typical arrangement is that half of the total is measured against Net Income targets and half against targets for overall Corporate Return on Invested Capital. In 1998, the Net Income results of the Company were $23.4 million, which was 73% above the Marginal level of the incentive target as set by the Committee. As a result, awards were made to executives for this factor for 1998. The average award for executive officers under this factor was 3.5%. 13

During 1998, the Company's result measured by Return on Invested Capital was 7.8%, and against the targets was Below Marginal. No incentive awards were made to executives for this factor. The remainder of each individual executive officer's incentive bonus is based on performance measures set by mutual agreement between the executive and the CEO. During 1998, the average incentive bonus for executive officers under this part of the plan was 27.2%. The CEO's incentive compensation is determined solely by the financial results of the Company for the year. For 1998, an incentive bonus of $42,350, or 9.1%, was paid to the CEO. (c) Executive officers receive stock option grants on a regular schedule to promote retention of proven executives, in recognition of job performance as an encouragement to advance corporate performance results, which in turn enhance the likelihood of increases in the value of Common Stock. In even-numbered years, stock options are granted to those executives and executive officers approved by the Committee and identified as having significant impact on the financial results and economic success and well-being of the Company. The size of stock option grants is determined based on job performance and the potential of each executive or executive officer to impact the costs, sales and/or profitability of the Company and may thus contribute to the value of the Common Stock held by stockholders. During 1998, stock options were granted to some eligible executives. In addition, stock options are granted to executive officers at other times based on other factors that the Committee determines to be relevant. Such actions are occasioned by election, promotion or extraordinary job performance results. During 1998, no such stock options were granted to executive officers. (d) The Board of Directors believes that ownership of Company stock by executives and executive officers is desirable in order to focus both short and long-term decision making on the best interests of the Company. To this end, during 1998, the Committee maintained the following policy guidelines: 1. Executive officers of the Company should own a minimum of Company stock approximating two times their annual base salary paid by the Company; and 2. Other executives (defined as those who are participants in the Company Management Incentive Plan) should own a minimum of Company stock approximating one times their annual base salary paid by the Company. Stock may be owned either directly, through the Company Stock Purchase Plan, the Company Employee Stock Ownership Plan, or in shares held in a deferred Management Incentive Plan account. Stock options not exercised are not considered "owned stock" for the purpose of this policy. The Committee realizes that time must be allowed to realize this targeted goal, but expects executives and executive officers to achieve such ownership within a three year time frame. (e) Under current levels of compensation and because certain plans, including grants under stock option plans prior to May 6, 1997, are "grandfathered" under current IRS regulations, the Company is unlikely to be affected by the one million dollar limit set forth in Section 162(m) of the Internal Revenue Code ("the Code") on the deductibility of compensation for purposes of calculating federal income tax. However, with respect to future years, the Committee intends to consider the application of Section 162(m) of the Code to the Company's compensation plans and practices, and will consider possible changes thereto that may be necessary to qualify future compensation paid to executive officers for deductibility under Section 162(m) of the Code to the extent that such changes would be consistent with the Company's compensation philosophy and in the best interests of the Company.

If the stockholders do not ratify the appointment of Andersen, the selection of auditors will be reconsidered by the Audit Committee and the Board of Directors. Representatives of Andersen are expected to be present at the Annual Meeting of Stockholders with the opportunity to make a statement, if they desire to do so, and to be available to respond to appropriate questions from the stockholders.
