                                PROXY STATEMENT

                               ----------------

                               ANNUAL MEETING OF
                                 STOCKHOLDERS

                               ----------------

   This Proxy Statement is furnished in connection with the solicitation by
the Board of Directors of Bio-logic Systems Corp. (the "Company") of proxies
to be voted at the Annual Meeting of Stockholders to be held at the Company's
headquarters, One Bio-logic Plaza, Mundelein, Illinois 60060 on August 23,
2001, at 10:00 A.M. Central Daylight Time, and at any adjournment thereof, for
the purposes set forth in the foregoing Notice of Annual Meeting of
Stockholders. The persons named in the enclosed proxy form will vote the
shares for which they are appointed in accordance with the directions of the
stockholders appointing them. If the enclosed form of proxy is properly
executed and returned, the shares of Common Stock represented thereby will be
voted in accordance with the instructions thereon. If no instructions are
indicated thereon, such shares will be voted in favor of the actions described
in this Proxy Statement and for the election of the nominees set forth under
the caption "Election of Directors." Any stockholder giving such a proxy may
revoke it at any time before it is exercised.

   Only holders of shares of Common Stock of record at the close of business
on June 25, 2001, are entitled to vote at the meeting. On the record date, the
Company had outstanding and entitled to vote 4,168,459 shares of Common Stock,
each entitled to one vote upon all matters to be acted upon at the meeting. A
majority in interest of the outstanding Common Stock represented at the
meeting in person or by proxy shall constitute a quorum. The affirmative vote
of a plurality of the Common Stock so represented is necessary to elect the
nominees for election as directors. Abstentions and broker non-votes are
counted for purposes of determining the presence or absence of a quorum for
the transaction of business. If a stockholder, present in person or by proxy,
abstains on any matter, the stockholder's Common Stock will not be voted on
such matter. Thus, an abstention from voting on any matter has the same legal
effect as a vote "against" the matter even though the stockholder may
interpret such action differently. Accordingly, except for determining the
presence or absence of a quorum for the transaction of business, broker non-
votes are not counted for any purpose in determining whether a matter has been
approved.

   The principal executive offices of the Company are located at One Bio-logic
Plaza, Mundelein, Illinois 60060. The Company expects to mail this Proxy
Statement and the accompanying form of proxy on or about June 28, 2001.

              EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT
                      AND CHANGE IN CONTROL ARRANGEMENTS

   In May 1986, the Company entered into an employment agreement with Gabriel
Raviv, Ph.D. The agreement is for two-year renewable periods and provides for
a salary with annual cost of living or other adjustments, benefits and bonuses
as the Board of Directors may determine which, during fiscal 2001, aggregated
$363,165. The agreement provides for Dr. Raviv's right to terminate his
employment upon any change in control of the Company and to receive upon such
termination compensation approximately equal to three times the present value
of the average annual compensation received by Dr. Raviv during the five years
preceding the year

                                       6


in which the change in control occurs, less any compensation arising out of
any stock option or the value of life insurance policies transferred to Dr.
Raviv upon such termination. The agreement includes confidentiality and
nondisclosure provisions and covenants not to compete for one year after
termination of employment.

   In September 1999, the Company entered into an employment agreement with
Roderick G. Johnson. The agreement is for an initial term of three years and
is renewable for successive one-year terms thereafter, and provides for a
salary to be reviewed at least annually by the Board of Directors, as well as
benefits and bonuses as the Board of Directors may determine which, during
fiscal 2001, aggregated $244,885. The agreement provides for the payment of
one and one-half years of base salary as defined, as well as certain expenses,
bonuses and benefits in the event of termination without cause by the Company.
The agreement further provides for the payment of three times base salary
should certain actions occur as a result of a change in control of the
Company. The agreement includes confidentiality and non-disclosure provisions
and covenants not to compete for eighteen months after termination of
employment.

   In connection with his appointment as Vice President, Sales & Marketing of
the Company in January 1994, the Company agreed to pay to Thomas S. Lacy a
severance payment equal to six months salary if his employment with the
Company is terminated at any time, such severance payment to be based upon his
minimum annual salary at the time of any such termination.

                      SECTION 16(a) BENEFICIAL OWNERSHIP
                             REPORTING COMPLIANCE

   Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's executive officers, directors and persons who beneficially own
more than 10% of a registered class of the Company's equity securities to file
with the SEC initial reports of ownership and reports of changes in ownership
of common stock and other equity securities of the Company. Based solely on
the Company's review of such forms furnished to the Company and written
representations from certain reporting persons, the Company believes that all
filing requirements applicable to the Company's executive officers, directors
and greater than 10% beneficial owners were complied with.

                  SELECTION OF INDEPENDENT PUBLIC ACCOUNTANTS

   The Board of Directors has selected Grant Thornton LLP as independent
public accountants for the Company for the fiscal year ending February 28,
2002. Grant Thornton was the independent public accountant for the Company for
its fiscal year ended February 28, 2001. A representative of Grant Thornton is
expected to be present at the annual meeting, with the opportunity to make a
statement, if he or she desires to do so, and is expected to be available to
respond to appropriate questions.

   If prior to the next annual meeting of stockholders such firm shall decline
to act or otherwise become incapable of acting, or if its engagement shall be
otherwise discontinued by the Board of Directors, the Board of Directors will
appoint other independent auditors whose selection for any period subsequent
to the next annual meeting will be subject to stockholder ratification at such
meeting.

Audit Fees

   The fees billed or expected to be billed by Grant Thornton for professional
services rendered for the audit of the Company's annual financial statements
for the fiscal year ended February 28, 2001 and the reviews of the financial
statements included in the Company's Quarterly Reports on Form 10-QSB for the
fiscal year totaled approximately $36,300.

                                       7


Financial Information Systems Design and Implementation Fees

   Grant Thornton LLP did not perform any financial information systems design
and implementation services for the Company for the fiscal year ended February
28, 2001.

All Other Fees

   The aggregate fees billed or expected to be billed by Grant Thornton for
other services rendered to the Company for the fiscal year ended February 28,
2001 totaled approximately $23,800.

   The Audit Committee has considered and determined that Grant Thornton's
provision of non-audit services to the Company is compatible with maintaining
Grant Thornton's independence.

Exhibit A--Audit Committee Charter

                                                                   June 5, 2001

MISSION STATEMENT

   The Company's independent auditor ultimately is accountable to the
Company's Board of Directors and Audit Committee, as representatives of the
shareholders, which, as such, have the ultimate authority and responsibility
to select, evaluate and, if appropriate, replace the independent auditor.

   The Audit Committee is responsible for ensuring that the independent
auditor periodically submits to the Audit Committee a formal written statement
delineating all relationships between the independent auditor and the Company,
consistent with Independence Standards Board Standard 1; for discussing with
the independent auditor any disclosed relationships or services that may
impact the objectivity and independence of the independent auditor; and for
recommending that the Board of Directors take appropriate action to oversee
the independent auditor's independence.

   The Audit Committee will assist the Board of Directors in fulfilling its
responsibilities to oversee the Company's financial and accounting operations.
The Audit Committee will review the Company's system of internal controls, its
financial reporting process, the audit process, and the Company's processes
for monitoring compliance with laws and regulations and the Company's business
practices. In performing its duties, the Audit Committee will maintain
effective working relationships with the Board of Directors, management, the
Company's internal accounting personnel and the independent auditors. The
Audit Committee will confirm with the independent auditor its understanding
that it has access to the Audit Committee at any time.

and cash flow statement or will become able to do so within a reasonable
period of time after his or her appointment to the audit committee. At least
one member of the Audit Committee shall have past employment experience in

                                      A-1


   Upon completion of the audit, the Audit Committee shall discuss with the
independent auditor and management the independent auditor's judgment about
the quality, not just the acceptability, of the Company's accounting
principles, as applied in the Company's financial reporting. As appropriate,
the discussion shall cover,

  . the consistency of the Company's accounting policies and their
    application;

  . the clarity and completeness of the Company's financial statements; and

  . policies relating to significant financial statement items, including
    timing of transactions and periods in which recorded.

   The Audit Committee shall inquire as to

    accounting personnel;

  . the cooperation that the independent auditor received during the audit;
    and

  . recommendations the independent auditor may have to improve the Company's
    internal financial controls, choice of accounting principles, or
    management reporting systems.

   The Audit Committee shall require the independent auditor, at least
annually, to

  . disclose to the Audit Committee, in writing, all relationships between
    the independent auditor and its related entities and the Company and its
    related entities that in the independent auditor's professional judgment
    may reasonably be thought to bear on independence;

  . confirm in the letter that, in its professional judgment, it is
    independent of the Company within the meaning of the federal securities
    laws; and

  . discuss the auditor's independence with the Audit Committee.

 Monitoring of Internal Controls Systems

   The Audit Committee shall meet separately in executive session, at least
annually, with the Company's principle accounting officer and internal auditor
to discuss

  . the scope of internal accounting and auditing procedures then in effect;

  . the Company's means for monitoring compliance by Company personnel with
    Company policies and procedures and applicable law; and

  . the extent to which recommendations made by the internal auditor or
    independent auditor have been implemented.

 Audit Committee Report

   The Audit Committee will report each year in the Company's proxy statement
whether:

  . the Audit Committee has reviewed and discussed the audited financial
    statements with management;

  . the Audit Committee has discussed with the independent auditors the
    matters required to be discussed by Statement of Accounting Standards No.
    61 (Codification of Statements on Auditing Standards, AU (S) 380), as it

  . based on the foregoing review and discussions, the Audit Committee
    recommended to the Board of Directors that the audited financial
    statements be included in the company's Annual Report on Form 10-KSB.

   The report shall not be deemed to be "soliciting material," or to be
"filed" with the Securities and Exchange Commission or subject to SEC
Regulations 14A or 14C.
