     All documents filed by the registrant pursuant to Sections 13, 14 and 15(d)
of the Securities Exchange Act of 1934, as amended (the "Exchange Act")
subsequent to the date of this registration statement and before the registrant

contained in a document incorporated herein by reference shall be deemed to be
modified or superseded for purposes of this registration statement to the extent

ITEM 4.  DESCRIPTION OF SECURITIES

     Pursuant to the Company's Certificate of Incorporation, as amended (the
"Certificate"), the Company is authorized to issue an aggregate of 150,000,000
shares of Common Stock, par value $.02 per share. As of December 31, 1998, there
were 6,655,539 shares of Common Stock outstanding. As of April 6, 1999, there
were 894 holders of record of Common Stock. The Common Stock is listed on the
Nasdaq SmallCap Market under the symbol "FUTR."

     The holders of outstanding shares of Common Stock are entitled to receive
dividends out of assets legally available therefor, if and when declared by the
Board of Directors and in such amounts as the Board of Directors may from time
to time determine. The shares of Common

                                      -2-
<PAGE>
 
Stock are neither redeemable nor convertible and the holders thereof have no
preemptive or subscription rights to purchase any securities of the Company.
Upon liquidation, dissolution or winding up of the Company, the holders of
Common Stock are entitled to receive, pro rata, the assets of the Company that
are legally available for distribution, after payment of all debts and other
liabilities of the Company. Each outstanding share of Common Stock is entitled
to one vote on all matters submitted to a vote of shareholders. There is no
cumulative voting in the election of directors.

DELAWARE STATUTORY BUSINESS COMBINATION PROVISION

     Section 203 of the Delaware General Corporation Law (the "DGCL") is
applicable to corporate takeovers in Delaware. Subject to certain exceptions set
forth therein, Section 203 of the DGCL provides that a corporation shall not
engage in any business combination with any "interested shareholder" for a 
three-year period following the date that such shareholder becomes an interested
shareholder unless (a) prior to such date, the board of directors of the
corporation approved either the business combination or the transaction that
resulted in the shareholder becoming an interested shareholder, (b) upon
consummation of the transaction that resulted in the shareholder becoming an
interested shareholder, the interested shareholder owned at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced (excluding certain specified shares) or (c) on or after such date, the
business combination is approved by the board of directors of the corporation
and by the affirmative vote of at least 66 2/3% of the outstanding voting
stock that is not owned by the interested shareholder. Except as specified
therein, an "interested shareholder" is defined to include any person that is
(i) the owner of 15% or more of the outstanding voting stock of the corporation,
(ii) an affiliate or associate of that corporation who or which and owned 15% or
more of the outstanding voting stock of the corporation at any time within three
years immediately prior to the relevant date, and (iii) an affiliate or
associate of the persons described in the foregoing clauses (i) or (ii).

     In its Certificate, the Company has elected not to be governed by the
restrictions imposed by Section 203 of the DGCL. Accordingly, in the event the
Company becomes the subject of a takeover or third party acquisition attempt, it
may not be able to avail itself of the benefits afforded by Section 203 of the
DGCL.

TRANSFER AGENT AND REGISTRAR

     The Transfer Agent and Registrar for the Common Stock is Harris Trust and
Savings Bank.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Under the Delaware General Corporation Law (the "DGCL"), a corporation has
the authority to indemnify any person who was or is a party or is threatened to
be made a party to an action (other than an action by or in the right of the
corporation) by reason of such person's service as a director of officer of the
corporation, or such person's service, at the corporation's request, as a
director, officer, employee or agent of another corporation or other enterprise,
against amounts paid and expenses incurred in connection with the defense or
settlement of such action, if such person acted in good faith and in a manner
such person reasonably believed to be in or not opposed to the corporation's
best interests and, with respect to any criminal action or proceeding, had no
reasonable cause to believe that such person's conduct was unlawful. If such
person has been judged liable to the corporation in any action or proceeding
brought by or in the right of the corporation, however, indemnification is only
permitted to the extent that the adjudicating court (or the court in which the
action was brought) determines, despite the adjudication of liability, that such
indemnification is proper.

     As permitted by the DGCL, the by-laws of the Company authorize the Company
to indemnify any officer, director and employee of the Company against amounts
paid or expenses incurred in connection with any action, suit or proceeding
(other than any such action by or in the right of the corporation) to which such
person is or is threatened to be made a party as a result of such position if
the Board of Directors or shareholders of or independent legal counsel to, the
Company, in a written opinion, determine that indemnification is proper. The by-
laws also limit the personal liability of directors for breach of fiduciary
duty, other than for breach of duty of loyalty, intentional misconduct or
violation of law, acts under Section 174 of the DGCL or with respect to any
transaction in which the director derives an improper personal benefit.

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 prospectus required by Section 10(a)(3) of the
     Securities Act of 1933, as amended (the "Securities Act");

              (ii) to reflect in the prospectus any facts or events arising
     after the effective date of this 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 this
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a twenty percent (20%) change in the maximum
     aggregate offering price set forth in the "Calculation of Registration Fee"
     table in the effective registration statement;

              (iii) to include any material information with respect to the plan
     of distribution not previously disclosed in this registration statement or
     any material change to such information in this registration statement ;

provided, however, that paragraphs 1(i) and 1(ii) above do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and 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 pursuant
to Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in this registration statement;

     2. that, for the purpose of determining any liability under the Securities
Act, each post-effective amendment to this 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;

     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; and

     4. that, for purposes of determining any liability under the Securities
Act, each filing of the registrant's annual report pursuant to Sections 13(a) or
15(d) of the Exchange Act that is incorporated by reference in this registration
statement shall be deemed to be a new registration

                                      -5-
<PAGE>
 
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.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling 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 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 and will be governed by the final
adjudication of such issue.

State of Illinois, on April 13, 1999.

ITEM 4.  DESCRIPTION OF SECURITIES

     Pursuant to the Company's Certificate of Incorporation, as amended (the
"Certificate"), the Company is authorized to issue an aggregate of 150,000,000
shares of Common Stock, par value $.02 per share. As of December 31, 1998, there
were 6,655,539 shares of Common Stock outstanding. As of April 6, 1999, there
were 894 holders of record of Common Stock. The Common Stock is listed on the
Nasdaq SmallCap Market under the symbol "FUTR."

     The holders of outstanding shares of Common Stock are entitled to receive
dividends out of assets legally available therefor, if and when declared by the
Board of Directors and in such amounts as the Board of Directors may from time
to time determine. The shares of Common

                                      -2-
Stock are neither redeemable nor convertible and the holders thereof have no
preemptive or subscription rights to purchase any securities of the Company.
Upon liquidation, dissolution or winding up of the Company, the holders of
Common Stock are entitled to receive, pro rata, the assets of the Company that
are legally available for distribution, after payment of all debts and other
liabilities of the Company. Each outstanding share of Common Stock is entitled
to one vote on all matters submitted to a vote of shareholders. There is no
cumulative voting in the election of directors.

DELAWARE STATUTORY BUSINESS COMBINATION PROVISION

     Section 203 of the Delaware General Corporation Law (the "DGCL") is
applicable to corporate takeovers in Delaware. Subject to certain exceptions set
forth therein, Section 203 of the DGCL provides that a corporation shall not
engage in any business combination with any "interested shareholder" for a 
three-year period following the date that such shareholder becomes an interested
shareholder unless (a) prior to such date, the board of directors of the
corporation approved either the business combination or the transaction that
resulted in the shareholder becoming an interested shareholder, (b) upon
consummation of the transaction that resulted in the shareholder becoming an
interested shareholder, the interested shareholder owned at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced (excluding certain specified shares) or (c) on or after such date, the
business combination is approved by the board of directors of the corporation
and by the affirmative vote of at least 66 2/3% of the outstanding voting
stock that is not owned by the interested shareholder. Except as specified
therein, an "interested shareholder" is defined to include any person that is
(i) the owner of 15% or more of the outstanding voting stock of the corporation,
(ii) an affiliate or associate of that corporation who or which and owned 15% or
more of the outstanding voting stock of the corporation at any time within three
years immediately prior to the relevant date, and (iii) an affiliate or
associate of the persons described in the foregoing clauses (i) or (ii).

     In its Certificate, the Company has elected not to be governed by the
restrictions imposed by Section 203 of the DGCL. Accordingly, in the event the
Company becomes the subject of a takeover or third party acquisition attempt, it
may not be able to avail itself of the benefits afforded by Section 203 of the
DGCL.

TRANSFER AGENT AND REGISTRAR

     The Transfer Agent and Registrar for the Common Stock is Harris Trust and
Savings Bank.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

                                      -3-
ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Under the Delaware General Corporation Law (the "DGCL"), a corporation has
the authority to indemnify any person who was or is a party or is threatened to
be made a party to an action (other than an action by or in the right of the
corporation) by reason of such person's service as a director of officer of the
corporation, or such person's service, at the corporation's request, as a
director, officer, employee or agent of another corporation or other enterprise,
against amounts paid and expenses incurred in connection with the defense or
settlement of such action, if such person acted in good faith and in a manner
such person reasonably believed to be in or not opposed to the corporation's
best interests and, with respect to any criminal action or proceeding, had no
reasonable cause to believe that such person's conduct was unlawful. If such
person has been judged liable to the corporation in any action or proceeding
brought by or in the right of the corporation, however, indemnification is only
permitted to the extent that the adjudicating court (or the court in which the
action was brought) determines, despite the adjudication of liability, that such
indemnification is proper.

     As permitted by the DGCL, the by-laws of the Company authorize the Company
to indemnify any officer, director and employee of the Company against amounts
paid or expenses incurred in connection with any action, suit or proceeding
(other than any such action by or in the right of the corporation) to which such
person is or is threatened to be made a party as a result of such position if
the Board of Directors or shareholders of or independent legal counsel to, the
Company, in a written opinion, determine that indemnification is proper. The by-
laws also limit the personal liability of directors for breach of fiduciary
duty, other than for breach of duty of loyalty, intentional misconduct or
violation of law, acts under Section 174 of the DGCL or with respect to any
transaction in which the director derives an improper personal benefit.

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 prospectus required by Section 10(a)(3) of the
     Securities Act of 1933, as amended (the "Securities Act");

              (ii) to reflect in the prospectus any facts or events arising
     after the effective date of this 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 this
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a twenty percent (20%) change in the maximum
     aggregate offering price set forth in the "Calculation of Registration Fee"
     table in the effective registration statement;

              (iii) to include any material information with respect to the plan
     of distribution not previously disclosed in this registration statement or
     any material change to such information in this registration statement ;

provided, however, that paragraphs 1(i) and 1(ii) above do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and 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 pursuant
to Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in this registration statement;

     2. that, for the purpose of determining any liability under the Securities
Act, each post-effective amendment to this 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;

     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; and

     4. that, for purposes of determining any liability under the Securities
Act, each filing of the registrant's annual report pursuant to Sections 13(a) or
15(d) of the Exchange Act that is incorporated by reference in this registration
statement shall be deemed to be a new registration

                                      -5-
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.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling 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 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 and will be governed by the final
adjudication of such issue.

     The Registrant. Pursuant to the requirements of the Securities Act of 1933

behalf by the undersigned, thereunto duly authorized, in the City of Chicago,
State of Illinois, on April 13, 1999.
