property shall at all times be within such Lender's control. Each Lender has

registration is available.

the meaning of Rule 501(a) promulgated under the Securities Act. Each Lender has

evidencing any Securities shall bear a legend in or substantially in the
following form:

         "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER, AND ARE SUBJECT TO,

         REGISTRATION UNDER THE 1933 ACT."

and year-end adjustments; and

         (c) contemporaneously with the filing or mailing thereof, copies of all

         (a) The Company shall not issue or sell any of its equity securities
(including securities convertible into equity securities) (collectively, the
"Future Shares") to any Person without first providing each Investor the right
to subscribe for its Proportionate Percentage (as defined in Section 8(f)) of
such Future Shares at the same price and on the same terms (including the method
of purchase; provided, however, that the Investors shall have the option of
purchasing Future Shares with cash, regardless of the method of purchase offered
to such Person) as shall be offered to such third party and which shall have
been specified by the Company in a writing delivered to each Investor (the
"Proposal"). The Proposal by its terms shall remain open and irrevocable for a
period of 20 days from the date it is delivered by the Company to each Investor
(the "Future Shares Exercise Period"). The Proposal shall also certify that the
Company has either (i) received a firm offer from a prospective purchaser, who
shall be identified in such certification, so that the Company in good faith
believes a binding agreement of sale is obtainable for consideration having a
fair market, cash equivalent or present value set forth in such certification;
or (ii) intends in good faith to make an offering of its securities at the price
and on the terms set forth in such certification.

         (b) Notice of each Investor's acceptance, in whole or in part, of the
Proposal made pursuant to Article 8(a) hereof shall be evidenced by a writing
signed by such Investor delivered to the Company prior to the end of the Future
Shares Exercise Period setting forth that portion of the Future Shares, as the
case may be, which the Investor elects to purchase (the "Notice of Purchase").
If an Investor does not deliver such written notice within the Future Shares
Exercise Period, such Investor shall be deemed to have elected not to purchase
all or any part of such Future Shares.

         (c) The Company shall promptly, in writing, inform each Investor which
purchases all the shares available to it ("Fully-Exercising Investor") of any
other Investor's failure to do likewise. During the ten-day period commencing
after the delivery by the Company of such information, each Fully-Exercising
Investor shall be entitled to obtain that portion of the Future Shares for which
Investors were entitled to subscribe but which were not subscribed for by the
Investors which is equal to the proportion that the number of shares of Common
Stock, and other securities, issued and

                                      - 9 -



held, or issuable (whether directly or indirectly) upon exercise of the Warrant,
or other derivative securities, held by such Fully-Exercising Investor, as the
case may be, then held, by such Fully-Exercising Investor bears to the total
number of shares of Common Stock, and other securities, issued and held, or
issuable (whether directly or indirectly) upon exercise of the Warrant, or other
derivative securities, held by such Fully-Exercising Investor, as the case may
be, then held, by all Fully-Exercising Investors who wish to purchase some of
the unsubscribed shares.

         (d) In the event that the Investors do not purchase all of the
remaining Future Shares pursuant to Article 8(c) above, the Company shall have
120 days from the expiration of the Future Shares Exercise Period to offer and
sell any part of such Future Shares not elected to be purchased by the Investors
(the "Refused Future Shares") to any other Person(s), but only upon terms and
conditions in all respects (including, without limitation, price, seniority,
dividends and liquidation, redemption and conversion rights) which are no more
favorable to such other Person(s) or less favorable to the Company than those
set forth in the Proposal; provided, however, that such sale be to the same
Person(s) or their affiliates identified in the Proposal, if so identified
pursuant to Article 8(a). In the event that the Company so sells the Refused
Future Shares to such identified Person(s), the sale to each Investor of the
Future Shares in respect of which a Notice of Purchase was delivered to the
Company by such Investor shall occur upon the closing of the sale to such other
Person(s) of Refused Future Shares (which closing shall include full payment to
the Company). If there are no Refused Future Shares, the sale to such Investor
of such Future Shares shall occur within 20 days of the expiration of the Future
Shares Exercise Period. In any event, the sale to such Investor of such Future
Shares shall be on the terms specified in the Proposal. Any Refused Future
Shares not purchased by such other Person(s) within such 120-day period shall
remain subject to this Article 8.

         (e) The term "Proportionate Percentage" in Article 8(a) shall mean, as
to any Investor, that percentage figure which expresses the ratio which (i) the
aggregate number of shares of Common Stock, and other securities, then (a)
outstanding and owned by such Investor and (b) issuable (whether directly or
indirectly) upon exercise of such Investor's Warrant bears to (ii) the aggregate
number of shares of Common Stock, and other securities, (a) outstanding and
owned by all Investors and (b) issuable (whether directly or indirectly) upon
conversion of the Warrants of all Investors. An Investor shall be entitled to
apportion the preemptive rights hereby granted it among its partners, members
and affiliates in such proportion as it deems appropriate.

         (f) Notwithstanding anything in this Article 8 to the contrary, a
Investor shall not be entitled to any preemptive rights in connection with any
issuance of shares of Common Stock (i) upon exercise of any of the Warrants (and
other convertible securities outstanding as of the date hereof); (ii) upon
exercise of options or warrants to purchase Common Stock of the Company that are
outstanding on the date of this Agreement; (iii) issued pursuant to, or upon
exercise of options granted under, the Company's existing stock plan entitled
MicroFinancial Incorporated 1998 Equity Incentive Plan; (iv) issued as a stock
dividend to accomplish a stock spilt or subdivision of shares or upon any
subdivision of shares; (v) issued in connection with the acquisition of another
corporation or other business entity by the Company by merger, purchase of
substantially all assets or other reorganization whereby the Company owns, upon
consummation of such acquisition, greater than fifty percent (50%) of the voting
power to elect the directors of such corporation or other business entity; (vi)
to underwriters and/or the public pursuant to a qualified public offering and
(vii) issued in any merger or consolidation of the Company, provided that such
merger or consolidation is approved by the Majority Investors; provided,
however, that notwithstanding anything in this Article 8(f) to the contrary, to
the extent legally permissible, the Investors (excluding any individuals) shall
have the preemptive rights described in Article 8(a) hereof to purchase a number

                                     - 10 -



of shares equal, in the aggregate, to 5% of the shares of the Company (other
than underwriters' warrants) sold in the qualified public offering (excluding
the over-allotment option), such shares to be allocated by the Investors on a
pro rata basis determined in accordance with the number of shares of Common
Stock issuable upon exercise of the Warrants; and provided further, that (i)
such shares are purchased at the price at which such securities are sold by the
underwriters to the public, (ii) the Investors shall purchase such shares
directly from the Company in a transaction that is exempt from registration
under the 1933 Act and that will close prior to or concurrently with the
qualified public offering, (iii) such offering shall occur on or after that date
which is one year from the date hereof; (iv) Investors who purchase such shares
shall be qualified institutional buyers (as such term is defined in Rule 144A
promulgated under the Securities Act); and (v) Investors shall comply with all
federal and state securities laws in connection with such purchase.
