PROXY STATEMENT


Annual Meeting of Stockholders To Be Held on Thursday, May 23, 2002

        This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of Harvard Bioscience, Inc. (the "Company") for use at the Annual Meeting of Stockholders of the Company to be held on Thursday, May 23, 2002 at 11:00 a.m. local time, at the offices of Goodwin Procter LLP, Exchange Place, 53 State Street, Boston, Massachusetts 02109, and any adjournments or postponements thereof (the "Annual Meeting").

        At the Annual Meeting, the stockholders of the Company will be asked to consider and vote upon:

        The Notice of Annual Meeting, Proxy Statement and Proxy Card are first being mailed to stockholders of the Company on or about April 24, 2002, in connection with the solicitation of proxies for the Annual Meeting. The Board of Directors has fixed the close of business on April 15, 2002 as the Record Date for the determination of stockholders entitled to notice of, and to vote at, the Annual Meeting (the "Record Date"). Only holders of Common Stock of record at the close of business on the Record Date will be entitled to notice of, and to vote at, the Annual Meeting. As of the Record Date, there were approximately 26,762,409 shares of Common Stock outstanding and entitled to vote at the Annual Meeting and approximately 100 stockholders of record. Each holder of a share of Common Stock outstanding as of the close of business on the Record Date will be entitled to one vote for each share held of record with respect to each matter submitted at the Annual Meeting.

        The presence, in person or by proxy, of holders of at least a majority of the total number of outstanding shares of Common Stock entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual Meeting. Shares held of record by stockholders or their nominees who do not return a signed and dated proxy or attend the Annual Meeting in person will not be considered present or represented at the Annual Meeting and will not be counted in determining the presence of a quorum. Directors are elected by a plurality of the votes cast if a quorum is present. In a plurality election, votes may only be cast in favor of or withheld from each nominee; votes that are withheld will be excluded entirely from the vote and will have no effect. This means that the two persons receiving the highest number of "FOR" votes will be elected as directors. Where the only matter to be considered at a meeting of stockholders is an uncontested election of directors by plurality, there are no "abstentions" or "broker non-votes" because (i) votes may only be cast in favor of or withheld from each nominee and (ii) shares of Common Stock held by a broker on behalf of a beneficial owner may be voted in the discretion of the broker if it does not receive voting instructions from the beneficial owner.

        Stockholders of the Company are requested to complete, date, sign and return the accompanying proxy card in the enclosed envelope. Common Stock represented by properly executed proxies received by the Company and not revoked will be voted at the Annual Meeting in accordance with the instructions contained therein. If instructions to the contrary are not given therein, properly executed proxies will be voted FOR the election of the nominees for Director listed in this Proxy Statement. It is


not anticipated that any matters other than the election of Directors will be presented at the Annual Meeting. If other matters are presented, proxies will be voted in accordance with the discretion of the proxy holders.

        Any properly completed proxy may be revoked at any time before it is voted on any matter (without, however, affecting any vote taken prior to such revocation) by giving written notice of such revocation to the Secretary of the Company, or by signing and duly delivering a proxy bearing a later date, or by attending the Annual Meeting, withdrawing the proxy and voting in person. Attendance at the Annual Meeting will not, by itself, revoke a proxy.

        The Annual Report to Shareholders of the Company, including consolidated financial statements for the year ended December 31, 2001 is being mailed to stockholders concurrently with this proxy statement. The Annual Report, however, is not part of the proxy solicitation material.


PROPOSAL 1
ELECTION OF DIRECTORS

        The Board of Directors of the Company currently consists of seven members and is divided into three classes of Directors, with three Directors in Class I, two Directors in Class II and two Directors in Class III. Directors serve for three-year terms with one class of Directors being elected by the Company's stockholders at each annual meeting to succeed the Directors of the same class whose terms are then expiring.

        At the Annual Meeting, two Class II directors will be elected to serve until the 2005 annual meeting of stockholders and until their successors are duly elected and qualified.

        The Board of Directors has nominated David Green and John F. Kennedy for re-election as the Class II directors. Unless otherwise specified in the proxy, it is the intention of the persons named in the proxy to vote the shares represented by each properly executed proxy for the re-election of Messrs. Green and Kennedy. The nominees have agreed to stand for re-election and, if elected, to serve as Directors. However, if any person nominated by the Board of Directors fails to stand for election or is unable to accept election, the proxies will be voted for the election of such other person or persons as the Board of Directors may recommend.

Vote Required

        The affirmative vote of holders of a plurality of the votes cast by holders of shares of Common Stock present or represented by proxy and entitled to vote on the matter at the Annual Meeting is required for the election of each nominee as a Director of the Company.

        THE BOARD OF DIRECTORS OF THE COMPANY UNANIMOUSLY RECOMMENDS A VOTE FOR THE ELECTION OF THE NOMINEES OF THE BOARD OF DIRECTORS, DAVID GREEN AND JOHN F. KENNEDY. PROXIES SOLICITED BY THE BOARD OF DIRECTORS WILL BE VOTED FOR EACH OF THE NOMINEES UNLESS INSTRUCTIONS TO WITHHOLD OR TO THE CONTRARY ARE GIVEN.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND ITS COMMITTEES

        The Board of Directors of the Company held eight meetings during the year ended December 31, 2001. During the year ended December 31, 2001, except for Mr. Dishman, each of the Directors attended at least 75% of the total number of meetings of the Board of Directors and of the committees of which he was a member. The Board has established an Audit Committee (the "Audit Committee") and a Compensation Committee (the "Compensation Committee").

Report of the Audit Committee

        The Board of Directors has established an Audit Committee, whose members during 2001 were John F. Kennedy (Chairman), Richard C. Klaffky, Jr. and Earl R. Lewis. The Board of Directors has determined that the members of the Audit Committee are "independent" under the rules of the Nasdaq Stock Market.

        The Audit Committee, among other things, makes recommendations concerning the engagement of an independent auditor, reviews the plans and results of the audit engagement with the independent auditor, approves professional services provided by the independent auditor, reviews the independence of the independent auditor, considers the range of audit and non-audit fees, reviews the adequacy of

4


the Company's internal financial reporting controls and performs such other oversight functions as may be requested from time to time by the Board of Directors. The Audit Committee met six times during 2001 and two times during the three months ended March 31, 2002.

        During the three months ended March 31, 2002, the Audit Committee:

        The Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2001, based on its review and the discussions described above.

        The Board of Directors has adopted a written charter setting forth the duties and responsibilities of the Audit Committee.

        During the year ended December 31, 2001, the Company paid the following fees to KPMG LLP, the Company's principal independent auditor:

Fees Paid to Independent Auditor
Audit Fees   $ 206,700
Financial Information Systems Design and Implementation Fees   $ 0
All other Fees:      
Audit related fees(1)   $ 169,800
Other non-audit related services(2)   $ 130,965
   
Total All other Fees   $ 300,765
(1)
Audit related fees consisted principally of audits of certain businesses acquired during the year.

(2)
Other non-audit fees consisted of tax compliance.

        The Audit Committee has considered whether the provision of the non-audit services above is compatible with maintaining the auditor's independence.

        The Audit Committee has selected KPMG LLP to serve as the Company's independent auditor for the year ending December 31, 2002. Representatives of KPMG LLP are expected to be present at the Annual Meeting and will have the opportunity to make a statement if they desire to do so. They are also expected to be available to respond to appropriate questions.

Submitted by the Audit Committee:
John F. Kennedy, Chairman

Report of the Compensation Committee

        The Compensation Committee reviews and recommends the compensation arrangements for the Company's executive officers, determines the options or stock to be granted to eligible persons under the Company's 2000 Stock Option and Incentive Plan (the "2000 Stock Plan") and takes other such action as may be required in connection with the Company's compensation and incentive plans. The Compensation Committee is responsible for the oversight of all of the Company's compensation policies and practices including benefits and perquisites. Compensation is defined as base salary, all forms of incentive pay, and stock option and restricted stock grants or any other plans directly or indirectly related to the Company's stock. Members of the Compensation Committee will be appointed from the Board of Directors annually at the first meeting of the Board following the annual meeting of stockholders. Not less than a majority of the Compensation Committee will consist of outside Directors. The composition of the Compensation Committee will reflect the requirements of Rule 16b-3 under the Securities Exchange Act of 1934 as in effect from time to time. The Compensation Committee met on January 17, 2002 and set the base salary and stock option grants for 2002 and approved the bonus for 2001 for the Chief Executive Officer, President and Chief Financial Officer.

        Compensation Philosophy.    The objective of the Company's Compensation Committee is to provide compensation that will attract and retain executives, motivate each executive toward the achievement of the Company's short and long-term financial goals and objectives and recognize individual contributions as well as overall business results. In order to achieve this objective, the primary focus of the Compensation Committee has been on the competitiveness of each of the key elements of executive compensation (base salary, bonus and stock and option grants) and the compensation package as a whole. In general, the Compensation Committee believes that total compensation should reflect both the relative performance of the Company among its peer group of public companies of similar size as well as the Company's performance as measured against its own financial objectives, and the longer term creation of shareholder value.

        Base Salary and Bonus.    Base compensation is set to be competitive with the peer group of the regional economy for public companies of similar size, taking into account historical levels and the level of responsibility, breadth of knowledge and the past performance of the executive. The relative importance of these factors varies, depending on the particular individual being reviewed. The Compensation Committee establishes the base salary of the Chief Executive Officer and reviews his recommendation with respect to the other senior executives. The cash bonus portion of each executive's compensation is determined based upon the achievement of certain individual and Company goals and other strategic accomplishments during the year. For the year ended December 31, 2001, the Company's financial objectives were based on the achievement of an established operating profit goal, the continued revenue growth of the company, and the maintenance of shareholder value during a time when a significant shift of the venture capital share ownership was transitioned to public ownership after the initial IPO lockup period expired in June of 2001.

        Stock Options.    The Compensation Committee believes that the equity ownership position of the Chief Executive Officer and the other members of the senior executive staff is a significant factor in aligning the long term interests of management and the stockholders. To ensure that high levels of performance occur over the long term, stock options granted to executives generally vest over a four-year period and expire ten years from the date of grant. In determining whether to grant stock options to executive officers, the Compensation Committee evaluates each officer's performance by examining criteria similar to that involved in the determination of base salary and bonuses. The Compensation Committee may also grant stock options for executive retention purposes.

        Compensation of the Chief Executive Officer.    The Company's financial performance is a crucial determinant in the Chief Executive Officer's overall compensation package. The Compensation

6


Committee also considered the completion of several important acquisitions and the Company's successful first year as a public company when determining Mr. Graziano's incentive compensation for the year ended December 31, 2001. Finally, the Compensation Committee reviewed information regarding the compensation paid to the Chief Executive Officer of comparable companies, and evaluated achievement of corporate, individual and organizational objectives for the year. Mr. Graziano's base salary for the year ended December 31, 2001 was set at $275,000. Mr. Graziano received a bonus for the year ended December 31, 2001 of $185,000. Mr. Graziano was not granted options to purchase shares of Common Stock in the year ended December 31, 2001.

        Deductibility of Executive Compensation.    The Internal Revenue Code of 1986, as amended (the "Code"), limits the federal income tax deductibility of compensation paid to the Company's Chief Executive Officer and to each of the other four most highly compensated executive officers. For this purpose, compensation can include, in addition to cash compensation, the difference between the exercise price of stock options and the value of the underlying stock on the date of exercise. The Company may deduct compensation with respect to any of these individuals only to the extent that during any year such compensation does not exceed $1 million or meets certain other conditions (such as stockholder approval). The Compensation Committee does not expect cash compensation for the year ending December 31, 2001 to the Chief Executive Officer or any other executive officer to be in excess of $1 million. If the deductibility of executive compensation becomes a significant issue, the Company's compensation plans and policy will be modified to maximize deductibility if the Company and the Committee determine that such action is in the best interests of the Company.

Richard C. Klaffky, Jr.

Director Compensation

        Non-employee Directors are reimbursed for their expenses incurred in connection with attending Board of Directors and committee meetings but do not receive cash compensation for their services as Directors. Directors are also eligible to participate in the 2000 Stock Plan. The 2000 Stock Plan provides that each non-employee Director, other than Messrs. Dick and Klaffky, will receive a one-time option grant of 10,000 shares vesting annually over three years upon initial election to the Board of Directors and an annual option grant of 2,500 shares vesting annually over three years following each annual meeting of stockholders.

Employment Agreements With Executive Officers

        The Company entered into employment agreements with each of Messrs. Graziano, Green and Warren. Each agreement is for a period of two years, other than Mr. Warren's agreement which was for one year. In August 2001, Mr. Warren resigned as Chief Financial Officer of the Company. Effective with his resignation, Mr. Warren terminated his employment agreement with the Company without good reason (as defined therein), accordingly, the Company has no further obligation to Mr. Warren pursuant to the agreement. Messrs. Graziano and Green's agreements automatically extend for two additional years on the second anniversary date unless either party has given notice that it does not wish to extend the agreement. Each agreement provides for the payment of base salary and incentive compensation and for the provision of certain fringe benefits to the executive. Under their respective employment agreements, the annual salary for Mr. Graziano is $275,000 and the annual salary for Mr. Green is $225,000. The agreements require our executive officers to refrain from competing with the Company and from soliciting Company employees for a period of 12 months following termination for any reason. Each agreement also provides for certain payments and benefits for an executive officer should his or her employment with the Company be terminated because of death or disability, by the

9


executive for good reason or by the Company without cause, as further defined in the agreements. In general, in the case of a termination by the executive officer for good reason, or by the Company without cause, the executive officer will receive up to two years' salary and bonus, an extension of benefits for one year and an acceleration of vesting for stock options and restricted stock which otherwise would vest during the next twenty-four months. Upon a change of control, as defined in the agreements, the executive officer is eligible for payment of up to three years' salary and bonus, an extension of benefits for one year and an acceleration of vesting for all outstanding stock options and restricted stock.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Loans to Officers in Connection with Option Exercises

        In September 2000, Mr. Graziano, the Company's Chief Executive Officer, and Mr. Green, the Company's President, each exercised options to purchase 740,228 shares of the Company's common

13


stock. Each of these officers paid substantially all of the exercise price for these shares by issuing promissory notes to the Company. The aggregate loans to Mr. Graziano are $789,000 and to Mr. Green are $789,000 pursuant to these promissory notes. Each of these promissory notes is due in September 2003 and bears interest at an annual rate of 10%. These promissory notes are secured by a pledge of all of the shares for which the exercise price was paid with the respective promissory notes as well as additional shares held by each of these officers. In February 2002, Mr. Green satisfied his promissory notes in full by payment to the Company of the principal amount of the notes and accrued interest.

Employment Agreement with Former Executive Officer

        In August 2001, effective with his resignation as Chief Financial Officer, Mr. Warren entered into a part-time employment agreement with the Company. The agreement is for a term of one year and provides that Mr. Warren commence work on a part-time basis in exchange for which the Company will compensate him $90,000 payable over the one year term of the agreement, accelerate the vesting of 28,445 stock options and continue Company benefits to the extent eligible. The agreement may be terminated by Mr. Warren for any reason without notice. If the Company terminates the agreement without cause, the Company must continue to compensate Mr. Warren for the remaining term of the agreement.


COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

        The Company's executive officers and directors and beneficial owners of more than 10% of its Common Stock are required under Section 16(a) of the Exchange Act to file reports of ownership and changes in ownership with the Securities and Exchange Commission. Copies of those reports must also be furnished to the Company.

        Based solely on a review of the copies of the reports furnished to the Company, and written representations from certain reporting persons that no other reports were required, the Company believes that during 2001: (i) Mr. Norige inadvertently failed to report his exercise of 3,000 stock options on December 28, 2001 and (ii) Mr. Warren inadvertently failed to report his exercise of 24,637 stock options on July 10, 2001.


MARKET VALUE

        On December 31, 2001, the closing price of a share of the Company's Common Stock on the Nasdaq National Market was $9.94.


EXPENSES OF SOLICITATION

        The Company will pay the entire expense of soliciting proxies for the Annual Meeting. In addition to solicitations by mail, certain directors, officers and regular employees of the Company (who will receive no compensation for their services other than their regular compensation) may solicit proxies by telephone, telegram or personal interview. Banks, brokerage houses, custodians, nominees and other fiduciaries have been requested to forward proxy materials to the beneficial owners of shares held of record by them and such custodians will be reimbursed for their expenses.
