               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE.

The following documents have been previously filed by MFIC Corporation (the
"Company") with the Securities and Exchange Commission and are incorporated
herein by reference:

1.       The Company's Annual Report on Form 10-K for the fiscal year ended
         December 31, 2001 ("Fiscal 2001");

2.       The descriptions of the Company's Common Stock which are contained in
         the registration statements filed under Section 12 of the Exchange Act,
         including any amendment or report filed for the purpose of updating
         such description.

All documents subsequently filed by the Company pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Exchange Act after the date of this Registration
Statement on Form S-8 and prior to such time as the Company files a
post-effective amendment to this Registration Statement on Form S-8 which
indicates that all securities offered hereby have been sold, or which
deregisters all such securities then remaining unsold, shall be deemed to be
incorporated by reference in this Registration Statement on Form S-8 and to be a
part hereof from the date of filing such documents.

ITEM 4.  DESCRIPTION OF SECURITIES.

Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Pursuant to the provisions of Section 145 of the Delaware General
Corporation Law, the Company has the power to indemnify certain persons,
including its officers and directors, under stated circumstances and subject to
certain limitations, for liabilities incurred in connection with services
performed in good faith for the Company or for other organizations at the
request of the Company.

         The By-Laws of the Company contain provisions to the general effect
that each director and officer shall be indemnified by the Company against
liabilities and expenses in connection with any threatened, pending or completed
legal proceeding to which he may be made a party or with which he may become
involved by reason of having been an officer or director of the Company or of
any other organization at the request of the Company. Indemnification is
available (except by court order) only if it is determined to be proper by a
majority of disinterested directors constituting a quorum, by the stockholders,
or by independent legal counsel in a written opinion. In order to be entitled to
indemnification, the indemnified person must have acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Company, and with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. In the case of an action
by or in the right of the Company, indemnification is precluded if such person
has been adjudged to be liable for negligence or misconduct in the performance
of his duty to the Company, unless and to the extent that the Court of Chancery
of the State of Delaware or the court in which the


                                      -3-
<PAGE>


action was brought shall determine that indemnification is proper. The Company
also has the power to obtain insurance indemnifying officers and directors of
the Company against any liability which it may deem proper, whether or not the
Company against any liability which it may deem proper, whether or not the
Company would otherwise have the power to indemnify such officer or director
pursuant to its By-Laws.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

Not applicable.

ITEM 8.  EXHIBITS.

(a) The following exhibits have been filed (except where otherwise indicated) as
part of this Registration Statement:

         23b      Consent of Deloitte & Touche LLP

ITEM 9.  UNDERTAKINGS.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

         (i)      To include any additional or changed material information on
                  the plan of distribution.

(2) For the purposes of determining any liability under the Securities Act, each
such post-effective amendment shall be deemed a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial BONA FIDE offering thereof.

(3) 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.

(4) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange
Act (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial BONA FIDE offering
thereof.

(5) Insofar as indemnification for liabilities arising under the Securities Act
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 Act 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 act and will be governed by the final adjudication of
such issue.

ITEM 4.  DESCRIPTION OF SECURITIES.

Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Pursuant to the provisions of Section 145 of the Delaware General
Corporation Law, the Company has the power to indemnify certain persons,
including its officers and directors, under stated circumstances and subject to
certain limitations, for liabilities incurred in connection with services
performed in good faith for the Company or for other organizations at the
request of the Company.

         The By-Laws of the Company contain provisions to the general effect
that each director and officer shall be indemnified by the Company against
liabilities and expenses in connection with any threatened, pending or completed
legal proceeding to which he may be made a party or with which he may become
involved by reason of having been an officer or director of the Company or of
any other organization at the request of the Company. Indemnification is
available (except by court order) only if it is determined to be proper by a
majority of disinterested directors constituting a quorum, by the stockholders,
or by independent legal counsel in a written opinion. In order to be entitled to
indemnification, the indemnified person must have acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Company, and with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. In the case of an action
by or in the right of the Company, indemnification is precluded if such person
has been adjudged to be liable for negligence or misconduct in the performance
of his duty to the Company, unless and to the extent that the Court of Chancery
of the State of Delaware or the court in which the

                                      -3-
action was brought shall determine that indemnification is proper. The Company
also has the power to obtain insurance indemnifying officers and directors of
the Company against any liability which it may deem proper, whether or not the
Company against any liability which it may deem proper, whether or not the
Company would otherwise have the power to indemnify such officer or director
pursuant to its By-Laws.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

Not applicable.

(a) The following exhibits have been filed (except where otherwise indicated) as
part of this Registration Statement:

         23b      Consent of Deloitte & Touche LLP

ITEM 9.  UNDERTAKINGS.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

         (i)      To include any additional or changed material information on
                  the plan of distribution.

(2) For the purposes of determining any liability under the Securities Act, each
such post-effective amendment shall be deemed a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial BONA FIDE offering thereof.

(3) 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.

(4) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange
Act (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial BONA FIDE offering
thereof.

                                      -4-
(5) Insofar as indemnification for liabilities arising under the Securities Act
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 Act 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 act and will be governed by the final adjudication of
such issue.

                                      -5-
