conversion, the Conversion Stock will have those rights and privileges, and be
subject to those restrictions, of the shares of Common Stock as set forth in the
Company's Certificate of Incorporation and Bylaws and this Note (including the
restrictions on transfer of Conversion Stock set forth in this Note), and the
Noteholder will receive the rights and be subject to the obligations applicable
to the purchasers of Common Stock.  This Note shall not be convertible and shall
not be converted into Conversion Stock if there is not an Initial Public
Offering on or before the Maturity Date.

          2.2  No Fractional Shares.  No fractional shares will be issued on

of its counsel, be necessary to authorize the issuance of a sufficient number of
shares of Conversion Stock into which this Note is to convert pursuant to
Section 2.1 above.

          2.4  Fully Paid Shares; Certificates.  All shares of Conversion Stock
               -------------------------------

Agreement in the form attached hereto as Annex A and incorporated herein by
                                         -------
reference.

     3.  No Rights or Liabilities as Shareholder.  This Note does not by itself
         ---------------------------------------
entitle the Noteholder to any voting rights or other rights as a shareholder of
the Company.  In the absence of conversion of this Note, no provisions of this
Note, and no enumeration herein of the rights or privileges of the holder shall
cause such holder to be a shareholder of the Company for any purpose by virtue
hereof.  Subject to the terms and conditions of this Note, Noteholder will have
all of the rights of a shareholder of the Company with respect to the Conversion
Stock from and after the Conversion Date until such time as Noteholder disposes
of the Conversion Stock.

     4.  Restrictions on Transfers.
         -------------------------

          4.1  No Transfers Unless Registered or Exempt.  Noteholder understands
               ----------------------------------------
that Noteholder may not transfer any shares of Conversion Stock unless such
shares are registered under the Securities Act and qualified under applicable
state securities laws or unless, in the opinion of counsel to the Company,
exemptions from such registration and qualification requirements are available.
Noteholder understands that only the Company may file a registration statement
with the Securities and Exchange Commission (the "SEC") and that the Company is
under no obligation to do so with respect to the Conversion Stock.  Noteholder
has also been advised that exemptions from registration and qualification may
not be available or may not permit Noteholder to transfer all or any of the
Conversion Stock in the amounts or at the times proposed by Noteholder.

          4.2  Rule 144.  In addition, Noteholder has been advised that SEC Rule
               --------
144 promulgated under the Securities Act, which permits certain limited sales of
unregistered securities, is not presently available with respect to the
Conversion Stock and, in any event, requires that the Conversion Stock be held
for a minimum of one (1) year, and in certain cases two (2) years, after they
have been purchased and paid for (within the meaning of Rule 144), before they
                    ------------
may be resold under Rule 144.  Noteholder understands that Rule 144 may
indefinitely restrict transfer of the Conversion Stock so long as Noteholder
remains an "affiliate" of the Company or if "current public information" about
the Company (as defined in Rule 144) is not publicly available.

          4.3  Disposition of Conversion Stock.  Noteholder hereby agrees that
               -------------------------------
Noteholder will make no disposition of the Conversion Stock (other than as
permitted by this Agreement) unless and until: (a) Noteholder has notified the
Company of the proposed disposition and provided a written summary of the terms
and conditions of the proposed disposition; (b) Noteholder has complied with all
requirements of this Note applicable to the disposition of the Conversion Stock
(including the restrictions on transfer); and (c) Noteholder has provided the
Company with written assurances, in form and substance satisfactory to counsel
for the Company, that (i) the proposed disposition does not require registration
of the Conversion Stock under the Securities Act or
<PAGE>

applicable state securities laws, or (ii) all appropriate actions necessary for
compliance with the registration requirements of the Securities Act or of any
exemption from registration available under the Securities Act (including Rule
144) and applicable state securities laws has been taken.

          4.4  Restriction on Transfer and Sale.  Upon and following any
               --------------------------------
conversion of this Note, no holder of any Conversion Stock shall effect any sale
or distribution of any of the Conversion Stock (which shall include any and all
voting securities received by such holder as or in connection with a stock
dividend, stock split or other recapitalization or similar distribution on or in
respect of the Conversion Stock) or any of the Company's other equity
securities, or of any securities convertible into or exchangeable for such
securities, during the period beginning on the closing of the Initial Public
Offering and ending 180 days after such closing.

          4.5  Legends.  Noteholder understands and agrees that the Company will
               -------
place appropriate legends on any stock certificate(s) evidencing the Conversion
Stock that may be required by state or federal securities laws, the Company's of
Incorporation or Bylaws, this Note any other agreement.  Noteholder agrees that,
to ensure compliance with the restrictions imposed by this Note, the Company may
issue appropriate "stop-transfer" instructions to its transfer agent, if any,
and if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.  The Company will not be
required (i) to transfer on its books any Conversion Stock that have been sold
or otherwise transferred in violation of any of the provisions of this Note, or
(ii) to treat as owner of such Conversion Stock, or to accord the right to vote
or pay dividends to any purchaser or other transferee to whom such Conversion
Stock have been so transferred.

     5.  Prepayment.  This Note may be prepaid, in its entirety (including the
         ----------
principal sum and interest accrued to the date of payment) without penalty or
premium; provided that prepayment cannot take place after the Company has filed
with the Securities and Exchange Commission a registration statement on Form S-
1, Form SB-1 or Form SB-2 (or any similar or successor form) for an Initial
Public Offering and for so long as any such registration statement remains
pending.

     6.  Usury Savings Clause.  The Company and the Noteholder intend to comply
         --------------------
at all times with applicable usury laws.  If at any time such laws would render
usurious any amounts due under this Note under applicable law, then it is the
Company's and the Noteholder's express intention that the Company not be
required to pay interest on this Note at a rate in excess of the maximum lawful
rate, that the provisions of this Section 6 shall control over all other
provisions of this Note which may be in apparent conflict hereunder, that such
excess amount shall be immediately credited to the principal balance of this
Note (or, if this Note has been fully paid, refunded by the Noteholder to the
Company), and the provisions hereof shall immediately be reformed and the
amounts thereafter decreased, so as to comply with the then applicable usury
law, but so as to permit the recovery of the fullest amount otherwise due under
this Note.
<PAGE>

     7.  Disclosure.  The Company agrees, for a period of two years following
         ----------
the date of this Agreement, to use reasonable commercial efforts to:

          (a)  make and keep material public information available within the
meaning of Rule 144(c) of the Securities Act at all times after ninety (90) days
after the closing of the Initial Public Offering; and

          (b) file with the SEC in a timely manner all reports and other
material documents required of the Company under the Securities Act and the
Securities Exchange Act of 1934, as amended (the "Exchange Act").

Company by the Noteholder in writing) reasonably promptly following the closing
of its Initial Public Offering. Conversion as described in this Section 2.1
shall occur only if the Company shall have conducted its Initial Public
Offering, provided that as a condition precedent or condition subsequent to
conversion (the election between which type of condition shall be the Company's
sole election in the Company's sole discretion), the Noteholder must surrender
this Note for conversion at the principal office of the Company. Incident to any
conversion, the Conversion Stock will have those rights and privileges, and be
subject to those restrictions, of the shares of Common Stock as set forth in the
Company's Certificate of Incorporation and Bylaws and this Note (including the
restrictions on transfer of Conversion Stock set forth in this Note), and the
Noteholder will receive the rights and be subject to the obligations applicable
to the purchasers of Common Stock.  This Note shall not be convertible and shall
not be converted into Conversion Stock if there is not an Initial Public
Offering on or before the Maturity Date.

          2.2  No Fractional Shares.  No fractional shares will be issued on
               --------------------
conversion of this Note.  If on any conversion of this Note a fraction of a
share results, the Company will pay the cash value of that fractional share,
calculated on the basis of a per share price of $10.50 per share (as
proportionally adjusted for stock splits, stock combinations, recapitalizations
and like events).

          2.3  Reservation of Stock.  Prior to any conversion of this Note
               --------------------
pursuant to Section 2.1 above, the Company will take such corporate action and
obtain such government consents and approvals as may, in the reasonable opinion
of its counsel, be necessary to authorize the issuance of a sufficient number of
shares of Conversion Stock into which this Note is to convert pursuant to
Section 2.1 above.

          2.4  Fully Paid Shares; Certificates.  All shares of Conversion Stock
               -------------------------------
issued upon the conversion of this Note shall be validly issued, fully paid and
non-assessable.  The certificates representing the shares of Conversion Stock
issued upon conversion hereof shall be delivered to the holder against surrender
of this Note.  The holder, by accepting this Note, undertakes and agrees to
accept such shares of Conversion Stock in full satisfaction of the outstanding
principal and accrued interest thereon in accordance with the terms of this
Note.  Anything to the contrary in this Note notwithstanding, the Company's
obligation to issue shares of Conversion Stock to any holder of this Note is
expressly conditioned upon compliance of such issuance with applicable federal
and state securities laws without registration or other qualification
thereunder.

Note, and no enumeration herein of the rights or privileges of the holder shall
cause such holder to be a shareholder of the Company for any purpose by virtue
hereof.  Subject to the terms and conditions of this Note, Noteholder will have
all of the rights of a shareholder of the Company with respect to the Conversion
Stock from and after the Conversion Date until such time as Noteholder disposes

not be available or may not permit Noteholder to transfer all or any of the

otherwise dispose of any of the Conversion Stock, except as permitted by this

Conversion Stock shall effect any sale or distribution of any of the Conversion
Stock (which shall include any and all voting securities received by such holder
as or in connection with a stock dividend, stock split or other recapitalization
or similar distribution on or in respect of the Conversion Stock) or any of the
Company's other equity securities, or of any securities convertible into or
exchangeable for such securities, during the period beginning on the closing of
the Initial Public Offering and ending 180 days after such closing.

          5.5  Legends.  Noteholder understands and agrees that the Company will
               -------
place appropriate legends on any stock certificate(s) evidencing the Conversion
Stock that may be required by state or federal securities laws, the Company's of
Incorporation or Bylaws, this Note any other agreement.  Noteholder agrees that,
to ensure compliance with the restrictions imposed by this Note, the Company may

and if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.  The Company will not be
required (i) to transfer on its books any Conversion Stock that have been sold
or otherwise transferred in violation of any of the provisions of this Note, or

with the Securities and Exchange Commission a registration statement on Form S-
1, Form SB-1 or Form SB-2 (or any similar or successor form) for an Initial
Public Offering and for so long as any such registration statement remains
pending.

     7.  Usury Savings Clause.  The Company and the Noteholder intend to comply
         --------------------
at all times with applicable usury laws.  If at any time such laws would render
usurious any amounts due under this Note under applicable law, then it is the
Company's and the Noteholder's express intention that the Company not be
required to pay interest

on this Note at a rate in excess of the maximum lawful rate, that the provisions
of this Section 7 shall control over all other provisions of this Note which may
be in apparent conflict hereunder, that such excess amount shall be immediately
credited to the principal balance of this Note (or, if this Note has been fully
paid, refunded by the Noteholder to the Company), and the provisions hereof
shall immediately be reformed and the amounts thereafter decreased, so as to
comply with the then applicable usury law, but so as to permit the recovery of
the fullest amount otherwise due under this Note.
