                           STANDBY PURCHASER AGREEMENT

_____________, 2005

______________________

______________________

Dear ____________:

         This letter confirms our agreement with respect to the intention of
Patriot National Bancorp, Inc., a Connecticut corporation (the "Company"), to
raise additional capital through a rights offering, with oversubscription
privileges, of up to ___________ shares (the "Underlying Shares") of the
Company's common stock, par value $2.00 per share (the "Common Stock"), to its
shareholders of record as of date to be determined ("Rights Offering") with the
participation of standby purchasers for any unsubscribed shares in the Rights
Offering (the Rights Offering and the offering to standby purchasers are
hereinafter referred to as the "Offering"). Capitalized terms used herein and
not defined herein shall have the meanings set forth in the Prospectus (as
hereinafter defined.)

         A REGISTRATION STATEMENT ON FORM SB-2 (THE "REGISTRATION STATEMENT")
RELATING TO THE COMPANY'S COMMON STOCK WAS FILED WITH THE SECURITIES AND
EXCHANGE COMMISSION ("SEC") ON APRIL __, 2005. NO OFFER TO BUY SECURITIES CAN BE
ACCEPTED AND NO PART OF THE PURCHASE PRICE CAN BE RECEIVED UNTIL THE
REGISTRATION STATEMENT HAS BECOME EFFECTIVE, AND ANY SUCH OFFER MAY BE WITHDRAWN
OR REVOKED, WITHOUT OBLIGATION OR COMMITMENT OF ANY KIND, AT ANY TIME PRIOR TO
NOTICE OF ITS ACCEPTANCE GIVEN AFTER THE EFFECTIVE DATE.

1.       PURCHASE AND SALE OF UNSUBSCRIBED SHARES.

         (a)      Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, the Company agrees to issue and
sell to you as a standby purchaser (the "Standby Purchaser") and the Standby
Purchaser agrees to purchase from the Company at the subscription price set
forth in the Prospectus (the "Subscription Price") up to __________ shares of
Common Stock (the "Standby Shares") which remain available for issuance in
accordance with the Rights Offering after the issuance of all shares of Common
Stock validly subscribed for through the exercise of rights (the "Rights"),
including the exercise of all oversubscription privileges, in the Rights
Offering (such remaining shares being hereinafter referred to as the
"Unsubscribed Shares").

         (b)      The Standby Purchaser and the Company acknowledge and agree
that the Company has entered into, or contemplates entering into, one or more
other Standby Purchase

<Page>

Agreements with certain other parties (collectively, the "Standby Purchasers")
on terms substantially similar to this Agreement, except that they may provide
for the purchase of a different maximum number of Standby Shares in Section 1(a)
and a different number of Minimum Shares (as defined in Section 1(c)). The
Unsubscribed Shares available for issuance to Standby Purchasers and any
additional shares which the Company shall have elected to issue shall be
allocated (to the extent any allocation thereof is necessary) as nearly as
possible on a pro rata basis among the Standby Purchasers based upon the number
of Standby Shares subscribed for by each such Standby Purchaser, after giving
effect to the limitation set forth in Section 2(a).

         (c)      In the event there is not a sufficient number of Unsubscribed
Shares remaining upon completion of the Rights Offering (including the exercise
of all oversubscription privileges) to allow you to purchase at least __________
shares pursuant to Section l(a) (the "Minimum Shares"), subject to the maximum
number of shares of Common Stock being offered for sale in the Offering as set
forth in the Registration Statement, the Company agrees to issue and sell to the
Standby Purchaser, and the Standby Purchaser agrees to purchase from the
Company, at the Subscription Price and otherwise in accordance with this
Agreement, sufficient additional shares so that the Standby Purchaser shall have
purchased the Minimum Shares, provided that the Company may need to reduce the
Minimum Shares committed to by the Standby Purchaser (on a pro rata basis with
all other Standby Purchasers) in order to ensure that the number of shares
issued by the Company in the Offering does not exceed the maximum number of
shares of Common Stock being offered for sale in the Offering. The shares to be
issued and sold to the Standby Purchaser (other than the Unsubscribed Shares) in
order that the Standby Purchaser may purchase the Minimum Shares are hereinafter
referred to as the "Additional Shares."

2.       LIMITATIONS ON ISSUANCE OF STANDBY SHARES.

         (a)      MAXIMUM HOLDING. The Standby Purchaser acknowledges and agrees
that, notwithstanding anything to the contrary herein contained or implied, the
Company will not issue to the Standby Purchaser shares of Common Stock in an
amount which, when aggregated with other shares of Common Stock owned or
controlled by the Standby Purchaser, would exceed 9.9% of the total issued and
outstanding shares of Common Stock upon completion of the Offering, including
shares issued pursuant to any Standby Purchase Agreements.

         (b)      FAILURE TO OBTAIN REGULATORY APPROVAL. The Standby Purchaser
hereby acknowledges and agrees that the Company may decline to issue shares of
Common Stock to the Standby Purchaser hereunder if, in the opinion of the
Company, the Standby Purchaser is required to obtain prior clearance or approval
of such purchase from any state or federal bank regulatory authority and if such
approval or clearance has not been obtained or if satisfactory evidence thereof
has not been presented to the Company prior to the expiration of the Offering.

3.       THE CLOSING.

         As soon as practicable following its determination of the number of
Unsubscribed Shares, the Company shall notify the Standby Purchaser of the
number of Standby Shares, if any, to be purchased by the Standby Purchaser
pursuant to Section l(a) and the number of Additional Shares, if any, to be
purchased by the Standby Purchaser pursuant to Section 1(c). The delivery of and
payment for the Standby Shares and the Additional Shares shall take place at the
offices

Offering, such time and date to be not more than five (5) business days after
the foregoing notification and to be specified therein (such time and date being
referred to as the "Closing Time," the date of the Closing Time being referred
to as the "Closing Date" and the consummation of the transaction being referred
to as the "Closing").

4.       DELIVERY OF STANDBY SHARES AND ADDITIONAL SHARES.

purchased by the Standby Purchaser hereunder, registered in the name of the
Standby Purchaser or its nominee(s), as the Standby Purchaser may specify in
writing at least three (3) days prior to the Closing Date, shall be delivered by

Purchaser's account, against delivery by the Standby Purchaser of the
