of Common Stock, then the Company shall use its best efforts, as soon as
practicable and in any event within 3 business days after receipt of written
notice from BACCFI exercising its exchange rights hereunder, to exchange such
portion of Common Stock for Series A Preferred Stock as will reduce the shares
of Common Stock currently or previously held by or currently issuable without

     Section 3. Registration Rights.

     (a) If, at any time after the date hereof, the Company proposes to register
any of its securities under the Securities Act (except pursuant to a
registration statement filed on Form S-8 or Form S-4 or such other form as shall
be prescribed under the Act for the same purposes), it will at each such time
give written notice (which notice shall state the intended method of disposition
thereof by the prospective sellers) to all holders of outstanding Registrable
Securities of its intention to do so and the proposed minimum offering price per
shares of such securities and upon the written request of any holder thereof
given within 10 days after the Company's giving of such notice, the Company,
will use its reasonable best efforts to effect the registration of the
Registrable Securities which it shall have been so requested to register by
including the same in such registration statement all to the extent required to
permit the sale or other disposition thereof in accordance with the intended
method of sale or other disposition given in each such request. If the

is for an

                                       3

<PAGE>

underwritten public offering, only Registrable Securities which are to be
included in the underwriting may be included in such registration, and the
Company shall have the right to designate the managing underwriter(s) in any
such underwritten public offering; provided that (i) the Company shall use its
reasonable best efforts to cause the managing underwriter(s) to include the
Registrable Securities requested to be included in the registration in the
underwriting; (ii) if the managing underwriter(s) advises the holders of the
Registrable Securities in writing that the total amount of securities which they
and the Company intend to include in such offering is sufficiently large to
materially and adversely affect the success of such offering, the amount of
securities to be offered for the accounts of all holders of Registrable
Securities shall be reduced pro rata (based upon the amount of securities each
such Person sought to include in the offering) to the extent necessary to reduce
the total amount of securities to be included in the offering to the amount
recommended by such managing underwriter(s) (which amount may be zero, if so
recommended by such managing underwriter(s). Any registration statement filed
pursuant to this subsection 3(c) may be withdrawn at any time at the discretion
of the Company.

     (b) If a registration under subsection 3(c) shall be in connection with an
underwritten public offering, each holder of Registrable Securities shall be
deemed to have agreed by acquisition of such Registrable Securities not to
effect any sale or distribution, including any sale pursuant to Rule 144 or Rule
144A, of any Registrable Securities, and to use such holder's reasonable best
efforts not to effect any such sale or distribution of any other equity security
of the Company or of any security convertible into or exchangeable or
exercisable for any equity security of the Company (other than as part of such
underwritten public offering) within seven days before or 90 days after the
effective date of such registration statement, provided that the Company hereby
also so agrees and agrees to use its reasonable efforts to cause each other
selling shareholder in such offering, so to agree.

     (c) (i) As a condition to the inclusion of a holder's Registrable
     Securities in any registration statement, each such holder of Registrable
     Securities requesting registration thereof will furnish to the Company such
     information with respect to such holder as is required to be disclosed in
     the registration statement (and the prospectus included therein) by the
     applicable rules, regulations and guidelines of the Commission and enter
     into a customary agreement requested by the Company regarding compliance
     with Rule 10b-18 promulgated under the Exchange Act and agreeing that such
     holder will, upon receipt of a notice from the Company pursuant to
     subsection 3(d)(iv) below, refrain from selling Warrants or Warrant Shares
     pursuant to the Registration Statement until the Company has filed and
     furnished to the holder an amended or supplemented prospectus as
     contemplated in subsection 3(d)(iv), but not longer than ninety (90) days
     after such notice. Failure of a holder to furnish such information or
     agreement shall not affect the obligation of the Company under this Section
     3 to the remaining holders who furnish such information.

         (ii) Each Holder of Registrable Securities requesting registration
     thereof agrees that such Holder will register shares of Common Stock to the
     greatest extent permitted by applicable law and to the extent that legal
     restrictions would not make the registration of Common Stock
     disadvantageous to such Holder.

                                       4

<PAGE>

     (d) If and whenever the Company is required under this Section 3 to use its
reasonable best efforts to effect the registration of Registrable Securities
under the Securities Act, the Company shall:

         (i) as expeditiously as possible prepare and file with the Commmission
     a registration statement on the appropriate form with respect to such
     Registrable Securities and use its reasonable best efforts to cause such
     registration statement to become effective as soon as practicable after
     such filing;

         (ii) as expeditiously as possible, prepare and file with the
     Commission such amendments and supplements (including post-effective
     amendments and supplements) to the registration statement covering such
     Registrable Securities and the prospectus used in connection therewith as
     may be necessary to keep such registration statement effective and usable
     for resale for a period necessary to complete the distribution of such
     securities, but in no event in excess of 12 months plus any period during
     which the holders of Registrable Securities are obligated to refrain from
     selling because the Company is required to amend or supplement the
     prospectus as contemplated under subsection 3(d)(iv), and to comply with
     the provisions of the Securities Act with respect to the disposition of all
     Registrable Securities covered by such registration statement during such
     period in accordance with the intended method of disposition of the sellers
     set forth therein;

         (iii) as expeditiously as possible, furnish to each seller of such
     Registrable Securities registered, or to be registered under the Securities
     Act, and to each underwriter, if any, of such Registrable Securities such
     number of copies of a prospectus and preliminary prospectus in conformity
     with the requirements of the Securities Act, and such other documents as
     such seller or underwriter may reasonably request in order to facilitate
     the public sale or other disposition of such Registrable Securities;

         (iv) as expeditiously as possible, notify each seller of such
     Registrable Securities if, at any time when a prospectus relating to such
     Registrable Securities, is required to be delivered under the Securities
     Act, any event shall have occurred as a result of which the prospectus then
     in use with respect to such Registrable Securities would include an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading or for any other reason it shall be necessary to amend or
     supplement such prospectus in order to comply with the Securities Act and
     prepare and furnish to all sellers as promptly as possible, and in any
     event within ninety (90) days of such notice, a reasonable number of
     copies of a supplement to or an amendment of such prospectus which will
     correct such statement or omission or effect such compliance;

         (v) as expeditiously as possible, use its reasonble best efforts to
     register or qualify, or obtain exemptions from such registration or
     qualification of, such Registrable Securities under such other securities
     or blue sky laws of such jurisdictions as such seller shall reasonably
     request and do any and all other acts and things which may be reasonably
     necessary to enable such seller to consummate the public sale or other
     disposition in each

                                       5

<PAGE>

     such jurisdiction of the Registrable Securities owned by such seller and
     included in such registration statement, provided that the Company shall
     not be required to consent to the general service of process or to qualify
     to do business in any jurisdiction where it is not then qualified;

         (vi) use its reasonable best efforts to keep the holders of such
     Registrable Securities informed of the Company's best estimate of the
     earliest date on which such registration statement or any post-effective
     amendment or supplement thereto will become effective and will promptly
     notify such holders and the managing underwriters, if any, participating in
     the distribution pursuant to such registration statement of the following:
     (A) when such registration statement or any post-effective amendment or
     supplement thereto becomes effective or is approved; (B) of the issuance by
     any competent authority of any stop order suspending the effectiveness or
     qualification of such registration statement or the prospectus then in use
     or the initiation or threat of any proceeding for that purpose; and (C) of
     the suspension of the qualification of any Registrable Securities included
     in such registration statement for sale in any jurisdiction;

         (vii) make available to its security holders, as soon as practicable,
     an earnings statement covering a period of at least twelve months which
     satisfies the provisions of Section 11(a) of the Securities Act and Rule
     158 thereunder;

         (viii) cooperate with the sellers of such Registrable Securities and
     the underwriters, if any, of such Registrable Securities; give each seller
     of such Registrable Securities, and the underwriters, if any, of such
     Registrable Securities and their respective counsel and accountants, such
     access to its books and records and such opportunities to discuss the
     business of the Company with its officers and independent public
     accountants as shall be necessary to enable them to conduct a reasonable
     investigation within the meaning of the Securities Act and, in the event
     that Registrable Securities are to be sold in an underwritten offering,
     enter into an underwriting agreement containing customary representations
     and warranties, covenants, conditions and indemnification provisions,
     including without limitation the furnishing to the underwriters of a
     customary opinion of independent counsel to the Company;

         (ix) provide a CUSIP number for all Registrable Securities not later
     than the effective date of the registration statement;

         (x) as to all registrations under subsection 3(a), pay all costs and
     expenses incident to the performance and compliance by the Company of this
     Section 3, including without limitation (A) all registration and filing
     fees; (B) all printing expenses; (C) all fees and disbursements of counsel
     and independent public accountants for the Company; (D) all blue sky fees
     and expenses (including fees and expenses of counsel in connection with
     blue sky surveys); (E) all transfer taxes; (F) the entire expense of any
     special audits required by the rules and regulations of the Commission; (G)

                                       6

<PAGE>

         (e)(i) The Company will indemnify and hold harmless each seller of
     Registrable Securities, each director, officer, employee and agent of each
     seller, and each other person, if any, who controls such seller within the
     meaning of the Securities Act or the Exchange Act from and against any and
     all losses, claims, damages, liabilities and legal and other expenses
     (including costs of investigation) caused by any untrue statement or
     alleged untrue statement of a material fact contained in any registration
     statement under which such Registrable Securities were registered under the
     Securities Act, any prospectus or preliminary prospectus contained therein
     or any amendment or supplement thereto, or caused by any omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading, except
     insofar as such losses, claims, damages, liabilities or expenses are caused
     by any such untrue statement or omission or alleged untrue statement or
     omission based upon information relating to such seller and furnished to
     the Company in writing by such seller expressly for use therein, and
     provided that the Company will not be liable to any Person who participates
     as an underwriter in the offering or sale of Registrable Securities or any
     other Person, if any, who controls such underwriter within the meaning of
     the Securities Act under the indemnity agreement in this subsection 3(e)
     with respect to any preliminary prospectus or the final prospectus or the
     final prospectus as amended or supplemented, as the case may be, to the
     extent that any such loss, claim, damage or liability of such underwriter
     or controlling Person results from the sale by such underwriter of
     Registrable Securities to a Person to whom there was not sent or given, at
     or prior to the written confirmation of such sale, a copy of the final
     prospectus or of the final prospectus as then amended or supplemented,
     whichever is most recent, if the Company has previously furnished copies
     thereof to such underwriter, or from a sale to a Person in a state where
     the offering has not been registered or qualified, if the Company has
     notified the seller and any underwriter involved in such sale of the states
     where the offering has been registered or qualified.

         (ii) It shall be a condition to the obligation of the Company to
     effect a registration of Registrable Securities under the Securities Act
     pursuant hereto that (X) each seller, severally and not jointly, indemnify
     and hold harmless the Company and each person, if any, who controls the
     Company within the meaning of the Securities Act or the Exchange Act to the
     same extent as the indemnity from the Company in the foregoing paragraph,
     but only with reference to any breach by such seller of any agreement
     between such seller, and the Company with respect to the offering and with
     reference to information relating to such seller furnished to the Company
     in writing by such seller expressly for use in the registration statement,
     any prospectus or preliminary prospectus contained therein or any amendment
     or supplement thereto and (Y) each seller, in the event that Registrable
     Securities are to be sold in an underwritten offering, enters into an
     underwriting agreement containing customary representations and warranties,
     covenants, conditions and indemnification provisions.

         (iii) In case any claim shall be made or any proceeding (including any
     governmental investigation) shall be instituted involving any indemnified
     party in respect of which indemnity may be sought pursuant to this
     subsection 3(e), such indemnified party

                                       7

<PAGE>

     shall promptly notify the indemnifying party in writing of the same,
     provided that failure to notify the indemnifying party shall not relieve it
     from any liability it may have to an indemnified party otherwise than under
     this subsection 3(e). The indemnifying party, upon request of the
     indemnified party, shall retain counsel reasonably satisfactory to the
     indemnified party to represent the indemnified party in such proceeding and
     shall pay the fees and disbursements of such counsel. In any such
     proceeding, any indemnified party shall have the right to retain its own
     counsel, but the fees and disbursements of such counsel shall be at the
     expense of such indemnified party unless (A) the indemnifying party shall
     have failed to retain counsel for the indemnified party as aforesaid, (B)
     the indemnifying party and such indemnified party shall have mutually
     agreed to the retention of such counsel or (C) representation of such
     indemnified party by the counsel retained by the indemnifying party would,
     in the reasonable opinion of the indemnified party, be inappropriate due to
     actual or potential differing interests between such indemnified party and
     any other party represented by such counsel in such proceeding, provided
     that the Company shall not be liable for the fees and disbursements of more
     than one additional counsel for all indemnified parties. The indemnifying
     party shall not be liable for any settlement of any proceeding effected
     without its written consent but if settled with such consent or if there be
     a final judgment for the plaintiff, the indemnifying party agrees to
     indemnify the indemnified party from and against any loss or liability by
     reason of such settlement or judgment.

     (f) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in subsection 3(f) is
due in accordance with its terms but is for any reason held by a court to be
unavailable on grounds of policy or otherwise, the Company or the applicable
sellers, as the case may be, shall contribute to the aggregate losses, claims,
damages and liabilities incurred (including legal or other expenses reasonably
incurred in connection with the investigating or defending of same) by the other
and for which such indemnification was sought. In determining the amount of
contribution to which the respective parties are entitled, there shall be
considered the relative benefits received by each party from the offering of the
securities included in the registration statement (taking into account the
portion of the proceeds of the offering realized by each), the parties' relative
knowledge and access to information concerning the matter with respect to which
the claim was asserted, the opportunity to correct and prevent any statement or
omission, and any other equitable considerations appropriate in the
circumstances; provided, however, that (i) in no case shall any seller of
Registrable Securities be required to contribute any amount in excess of the
total public offering price of the Registrable Securities sold by him and (ii)
no person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. For purposes of this
subsection 3(f), each person who controls any seller of Registrable Securities
or the Company shall have the same rights to contribution as such seller or the
Company. Any party entitled to contribution shall, promptly after receipt of
notice of commencement of any action, suit or proceeding against such party in
respect of which a claim for contribution may be made against the Company or the
seller of Registrable Securities under this subsection 3(h), notify the Company
or such seller, as the case may be, but the omission to so notify the Company or
such seller, as the case may be, shall not relieve it from any other obligation
it may have hereunder or otherwise.

                                       8

     Section 4. Available Information. The Company shall take such reasonable
action and file such information, documents and reports as shall be required by
the Commission as a condition to the availability of Rule 144 and Rule 144A
promulgated under the Securities Act, or any successor provisions.

     Section 5. Amendments and Waivers. Any provision of this Registration
Rights Agreement may be amended, supplemented, waived, discharged or terminated
by a written instrument signed by the Company and the Holders of not less than a
majority of the aggregate outstanding Registrable Securities, voting as a single
group.

     Section 6. Specific Performance. The parties agree that irreparable damage
will result in the event that the obligations of the Company under this
Registration Rights Agreement are not specifically enforced, and that any
damages available at law for a breach of any such obligations would be
inadequate. Therefore, the Holders of the Registrable Securities shall have the
right to specific performance by the Company of the provisions of this
Registration Rights Agreement, and appropriate injunctive relief may be applied
for and granted in connection therewith. The Company hereby irrevocably waives,
to the extent that it may do so under applicable law, any defense based on the
adequacy of a remedy at law which may be asserted as a bar to the remedy of
specific performance in any action brought against the Company for specific
performance of this Registration Rights Agreement by the Holders of Registrable
Securities. Such remedies and all other remedies provided for in this
Registration Rights Agreement shall, however, be cumulative and not exclusive
and shall be in addition to any other remedies which may be available under this
Registration Rights Agreement.

     Section 7. Notices.

     (a) Any notice or demand to be given or made by the Holders of Registrable
Securities to or on the Company pursuant to this Registration Rights Agreement
shall be sufficiently given or made if sent by registered mail, return receipt
requested, postage prepaid, addressed to the Company at 87 Grandview Avenue,
Waterbury, CT 06708, Attn: Chief Financial Officer.

     (b) Any notice to be given by the Company to the Holders of Registrable
Securities shall be sufficiently given or made if sent by registered mail,
return receipt requested, postage prepaid, addressed to such holder as such
Holder's name and address shall appear on the Warrant Register or the Common
Stock or Series A Preferred Stock registry of the Company, as the case may be.

     Section 8. Binding Effect. This Registration Rights Agreement shall be
binding upon and inure to the sole and exclusive benefit of the Company, its
successors and assigns, and the registered Holders from time to time of the
Registrable Securities.

     Section 9. Continued Validity. A Holder of Registrable Securities shall
continue to be entitled with respect to such Registrable Securities to all
rights and subject to all obligations to

                                       9

<PAGE>

which it would have been entitled or subject as a Holder of Registrable
Securities under Section 2 and 3 of this Registration Rights Amendment.

     Section 10. Counterparts. This Registration Rights Agreement may be
executed in one or more separate counterparts and all of said counterparts taken
together shall be deemed to constitute one and the same instrument.

     Section 11. New York Law. THIS REGISTRATION RIGHTS AGREEMENT AND EACH
WARRANT CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
