               A = the average of the closing sale prices of the Common Stock
               for the thirty (30) trading days immediately prior to (but not

     Quotation System ("NASDAQ"), then the Fair Market Value shall be equal to

     Value is being determined. As used in this subparagraph (a), "market price"

                                      -2-
<PAGE>
 
     such trading day shall be the average of the closing prices on such day of
     the Common Stock on all domestic primary national securities exchanges on
     which the Common Stock is then listed, or, if there shall have been no
     sales on any such exchange on such day, the average of the highest bid and
     lowest asked prices on all such exchanges at the end of such day, or if the
     Common Stock shall not be so listed, the average of the representative bid
     and asked prices at the end of such trading day as reported by NASDAQ.

          (b) If the Common Stock is not listed or admitted for trading on any
     national securities exchange or quoted on NASDAQ, then the Fair Market
     Value of one share of Common Stock shall be equal to the fair market value
     of the entire capital equity of the Company taken as a whole, divided by
     the number of shares of Common Stock (on a fully diluted basis) then issued
     (or deemed issued) and outstanding, without premium for control and without
     discount for minority interest or restriction on transfer, as determined by
     the Company's Board of Directors in good faith and set forth in writing to
     FSC within fifteen (15) days after the occurrence of the event which
     requires the valuation, unless FSC shall object in writing within five (5)
     days after receipt of the Board of Directors' determination, in which case
     the Fair Market Value shall be determined (x) by a reputable independent
     appraiser selected by mutual agreement of the Company and FSC and set forth
     in writing to the Company and FSC within thirty (30) days after the
     occurrence of the event which requires the valuation, or (y) (if the
     Company and FSC shall have been unable to agree upon an appraiser within
     ten (10) days after FSC's objection to the Board of Directors'
     determination of Fair Market Value) as the average of the two (2) closest
     appraisals by three (3) reputable independent appraisers, one chosen by the
     Company, one chosen by FSC, and the third selected by the other two (2)
     appraisers, set forth in writing within sixty (60) days after the
     occurrence of the event which requires the valuation.  If the Fair Market
     Value as determined by appraisal pursuant to clause (x) above or by the
     average of the appraisals determined in accordance with clause (y) above,
     as the case may be, is greater than the Fair Market Value determined by the
     Board of Directors, then all expenses of such appraisals shall be paid by
     the Company, and in all other circumstances, such appraisal expenses shall
     be paid by FSC.

     2.2.   Warrant Agent In the event that a bank or trust company shall have
            -------------

successor, as the case may be, on exercise of this Warrant pursuant to this
Section 2.

shall give notice to the party required to provide indemnification pursuant to
this Section 3.8 (the "indemnifying party") promptly after such
                       ------------------                     
indemnified party acquires actual knowledge of any claim as to which indemnity
may be sought, and shall permit the indemnifying party (at its expense) to
assume the defense of any claim or any litigation resulting therefrom; provided
                                                                       --------

claim or litigation. shall be acceptable to the indemnified party, and the
indemnified party may participate in such defense at such party's expense; and
provided, further, that the failure by any indemnified party to give notice as
--------  -------
provided in this paragraph (c) shall not relieve the indemnifying party of its
obligations under this Section 3.6 except to the extent that the failure results
in a failure of actual notice to the indemnifying party and such indemnifying
party is damaged solely as a result of the failure to give notice. No
indemnifying party. in the defense of any such claim or litigation, shall.
except with the consent of each indemnified party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party
of a release from all liability in respect to such claim or litigation. The
reimbursement required by this Section 3.6 shall be made by periodic payments
during the course of the investigation or defense, as and when bills are
received or expenses incurred.

     3.7. Contribution in Lieu of Indemnification. If the indemnification
          ---------------------------------------                        
provided for in Section 3.6 hereof is unavailable to a party that would have
been an indemnified party under any such Section in respect of any losses,
claims, damages or liabilities (or actions in respect thereof) referred to
therein, then each party that would have been an indemnifying party thereunder
shall, in lieu of indemnifying such indemnified party, contribute to the amount
paid or payable by such indemnified party as a result of such losses, claims,
damages or liabilities (or actions in respect thereof) in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one
hand and such indemnified party on the other in connection with the statements
or omissions which resulted in such losses, claims, damages or liabilities (or
actions in respect thereof). The relative fault shall be determined by reference
to. among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the indemnifying party or such indemnified
party and the parties' relative intent. knowledge. access to information and
opportunity to correct or prevent such statement or omission. The Company and
each Holder of Registrable Securities agree that it would not be just

and equitable if contribution pursuant to this Section 3.7 were determined by

claims, damages or liabilities (or actions in respect thereof) referred to above
in this Section 3.7 shall include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim. No Person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be

                                      -10-
<PAGE>
 
entitled to contribution from any Person who was not guilty of such fraudulent
misrepresentation. Each Holder's liability hereunder with respect to any
particular Registration shall be limited to an amount equal to the net proceeds
received by such Holder from the Registrable Securities sold by such Holder in
such Registration.

     3.8.  Rule 144 Requirements; Form S-3. The Company will make every effort
           -------------------------------

the Commission) and to make publicly available and available to the Holders of
Registrable Securities, pursuant to Rule 144 of the Commission under the
Securities Act ("Rule 144"), such information as shall be necessary to enable
the Holders of Registrable Securities to make sales of Registrable Securities

Securities, upon request made by such Holder a written statement signed by the
Company, addressed to such Holder, describing briefly the action the Company has
taken or proposes to take to comply with the current public information
requirements of Rule 144. The Company will, at the request of any Holder of
Registrable Securities, upon receipt from such Holder of a certificate
certifying (a) that such Holder has held such Registrable Securities for a
period of not less than two (2) consecutive years, (b) that such Holder has not
been an affiliate (as defined in Rule 144) of the Company for more than the
ninety (90) preceding days, and (c) as to such other matters as may be necessary
to meet the requirements of Rule 144, remove from the stock certificates
representing such Registrable Securities that portion of any restrictive legend
which relates to the Registration provisions of the Securities Act.

           -------------------------------------------                          
Securities may participate in any underwritten Registration pursuant to this
Section 3 unless such Holder of Registrable Securities (a) agrees to sell such
Holder's securities on the basis provided in any underwriting arrangements
approved by the Persons entitled, under the provisions hereof, to approve such
arrangements, and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required by the terms of such underwriting arrangements. Any Holder of
Registrable Securities to be included in any underwritten Registration shall be
entitled at any time to withdraw such Registrable Securities from such
Registration prior to its effective date in the event that such Holder shall
disapprove of any of the terms of the related underwriting agreement.

     3.10. Miscellaneous.

     Securities hereunder.

Company shall (i) effect a capital reorganization, reclassification or
recapitalization, (ii) consolidate with or merge into any other person, or (iii)

such reorganization, recapitalization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise immediately prior
to such consummation or effective date, the stock and other securities and
property (including cash) to which such holder would have been entitled upon
such consummation (or thereafter as a result of such consummation, including in
connection with any dissolution of the Company) if such holder had so exercised
this Warrant immediately prior thereto, all subject to further adjustment
thereafter as provided in Sections 5 and 7 hereof.

     6.2.  Appointment of Trustee for Warrant Holders Upon Dissolution. In the
           -----------------------------------------------------------

dividend, reverse stock split or other subdivision of the Company's Common Stock
(a "STOCK EVENT"), then the number of shares of Common Stock to be received by
the holder of this Warrant shall be appropriately adjusted such that the
proportion of the number of shares issuable hereunder to the total number of
shares of the Company outstanding (on a fully diluted basis) prior to such Stock
Event is equal to the proportion of the number of shares issuable hereunder
after such Stock Event to the total number of shares of the Company outstanding
(on a fully diluted basis) after such Stock Event. No adjustment to the Exercise
Price shall be made in connection with any adjustment of the number of shares of
Common Stock receivable upon exercise of this Warrant, except that the Exercise
Price shall be proportionately decreased or increased upon the occurrence of any
stock split or other subdivision of the Common Stock.

     7.2.  Other Securities. In case any Other Securities shall have been
           ----------------                                              
issued, or shall then be subject to issue, upon the conversion or exchange of
any stock (or Other Securities) of the Company (or any other issuer of Other
Securities or any other entity referred to in Section 6 hereof) or to
subscription, purchase or other acquisition pursuant to any rights or options
granted by the Company (or such other issuer or person), the holder hereof shall
be entitled to receive upon exercise hereof such amount of Other Securities (in
lieu of or in addition to Common Stock) as is determined in accordance with the
terms hereof, treating all references to Common Stock herein as references to
Other Securities to the extent applicable, and the computations, adjustments and
readjustments provided for in this Section 7 with respect to the Exercise Price
and the number of shares of Common Stock issuable upon exercise of this Warrant
shall be made as nearly as possible in the manner so provided and applied to
determine the amount of Other Securities from time to time receivable on the
exercise of the Warrant, so as to provide the holder of the Warrant with the
benefits intended by this Section 7 and the other provisions of this Warrant.

8.   NO IMPAIRMENT. The Company will not, by amendment of its charter or through
     -------------                                                              
any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary action, avoid or seek to
avoid the observance or performance of any of the terms of the Warrant, but will
at all times in good faith assist in the carrying out of all such terms and in
the taking of all such action as may be necessary or appropriate in order to
protect the rights of the holder of the Warrant against impairment. Without
limiting the generality of the foregoing, the Company (i) will take all such
action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and non-assessable shares of stock on the exercise
of the Warrant from time to time outstanding, and (ii) will not transfer all or
substantially all of its properties and assets to any other person (corporate or
otherwise), or consolidate with or merge into any other person or permit any
other person to consolidate with or merge into the Company (if the Company is
not the surviving entity), unless such other person shall expressly assume in
writing and will be bound by all the terms of this Warrant.

     -----------------------------                                            
any adjustment or readjustment in the shares of Common Stock issuable on the
exercise of this Warrant, the Company at its expense will promptly prepare a
certificate setting forth such adjustment or readjustment, or stating the
reasons why no adjustment or readjustment is being made, and showing, in detail,
the facts upon which any such adjustment or readjustment is based, including a
statement of (i) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
issued or sold,(ii) the number of shares of Common Stock then outstanding or
deemed to be outstanding on a fully diluted basis, and (iii) the Exercise Price
and the number of shares of Common Stock to be received upon exercise of this
Warrant, in effect immediately prior to such adjustment or readjustment and as
adjusted and readjusted (if required by Section 7) on account thereof. The
Company will forthwith mail a copy of each such certificate to the holder of the
Warrant, and will, on the written request at any time of any holder of a
Warrant, furnish to such holder a like certificate setting forth the
calculations used to determine such adjustment or readjustment. At its option,
the holder of the Warrant may confirm the adjustment noted on the certificate by
causing such adjustment to be computed by the Company's independent accounting
firm or another independent certified public accountant at the expense of the
Company.
