|           | President & CEO

Dear Madam:

RBC Dominion Securities Inc. (the Lead Agent) and MGI
Securities Inc. (together with the Lead Agent, the Agents) understand
that Bridgeport Ventures Inc. (the Corporation) proposes to issue and
sell up to 15,000,000 units (the Initial Units) at a price of $1.00 per
Initial Unit (the Issue Price) for gross proceeds of up to $15,000,000.
Each Initial Unit shall consist of one common share in the capital of the
Corporation (a Unit Share) and one-half of one common share purchase
warrant (each whole common share purchase warrant a Warrant).

Each Warrant shall entitle the holder thereof to purchase one
common share in the capital of the Corporation (a Warrant Share) at a
price of $1.40 at any time prior to 5:00 p.m. (Toronto time) on the date that is
two years following the Closing Date (as defined below). The Warrants shall be
created and issued pursuant to a warrant indenture (the Warrant
Indenture) to be dated as of the Closing Date (as defined below) between
the Corporation and the Transfer Agent (as defined below).

The Agents also understand that the Corporation proposes to
grant to the Agents an option (the Over-Allotment Option), exercisable
in whole or in part, at any time until the date which is 30 days following the
Closing Date (as defined herein), to arrange for the issuance and sale of up to
an additional 2,250,000 units of the Corporation, representing 15% of the number
of Initial Units issued pursuant to the Offering (the Additional
Units), at a price per Additional Unit equal to the Issue Price, for the
purposes of covering over-allotments, if any, and for market stabilization
purposes in connection with the Offering (as more particularly described in
section 15 hereof). The Over-Allotment Option may be exercisable by the Agents
in respect of: (i) Additional Units at the Offering Price; or (ii) additional
Units Shares (the Additional Unit Shares) at a price of $0.94 per
Additional Unit Share; or (iii) additional Warrants (the Additional
Warrants) at a price of $0.12 per Additional Warrant; or (iv) any
combination of Additional Units and/or Additional Unit Shares and/or Additional
Warrants, so long as the aggregate number of Additional Unit Shares and
Additional Warrants which may be issued under the Over-Allotment Option does not
exceed 2,250,000 Additional Unit Shares and 1,125,000 Additional Warrants. In
the event that the Over-Allotment Option is exercised, any Additional Units
and/or Additional Unit Shares and/or Additional Warrants issued thereunder shall
be deemed to form part of the Offering for the purposes hereof and all of the
terms and conditions relating to the Closing shall apply to the Over-Allotment
Closing (as defined herein).

Unless the context otherwise requires, references herein to the
Offered Units, Unit Shares, Warrants and
Warrant Shares shall assume the exercise of the Over-Allotment Option
and include the Additional Units, Additional Unit Shares, Additional Warrants
and Additional Warrant Shares issuable upon exercise of the Additional Warrants,
respectively. The offering of the Offered Units by the Corporation is referred
to as the Offering.

The Agents further understand that the Corporation has prepared
and filed a preliminary short form prospectus with respect to the qualification
for distribution to the public of the Offered Units in each of the Qualifying
Provinces (as hereinafter defined) and will prepare and file a (final) short
form prospectus and all other necessary documents in order to qualify the
Offered Units for distribution to the public in each of the Qualifying
Provinces.

Subject to the terms and conditions contained in this
Agreement, the Corporation hereby appoints the Agents to act as the sole and
exclusive agents to the Corporation, and the Agents hereby agree to act as the
agents of the Corporation, to effect the sale of the Offered Units on behalf of
the Corporation on a best efforts basis to Purchasers (as hereinafter defined)
resident in the Qualifying Provinces and in those jurisdictions outside of
Canada (including the United States (as hereinafter defined)) as may be agreed
to by the Corporation and the Agents, acting reasonably, through private
placements or other offerings on an exempt basis and provided that the
Corporation shall not become obligated to file a registration statement or
prospectus outside of Canada. In addition, the Corporation hereby agrees to
issue and sell the Additional Units to the extent that Over-Allotment Option
granted to the Agents pursuant to this Agreement is exercised by the Agents. It
is understood and agreed that the Agents are under no obligation to purchase any
of the Offered Units, although the Agents may subscribe for Offered Units if
they so desire.

In consideration of the services to be rendered by the Agents
in connection with the sale of the Offered Units hereunder, the Corporation
agrees to pay to the Agents a commission (the Commission) equal to 6%
of the gross proceeds of the Offering, including proceeds realized from the
exercise by the Agents of the Over-Allotment Option, if any. The Commission
shall be due and payable at the applicable Closing Time (as hereinafter
defined). As additional compensation for the services to be rendered by the
Agents in connection with the sale of the Offered Units, the Corporation shall
grant to the Agents compensation options (the Compensation Options)
entitling the Agents to subscribe for and purchase up to such number of units
(the Compensation Units) as is equal to 6% of the aggregate number of
Offered Units sold pursuant to the Offering, including Offered Units sold
pursuant to the exercise by the Agents of the Over-Allotment Option, if any.
Each Compensation Unit will be comprised of one Unit Share and one-half of one
Warrant. The Compensation Options may be exercised, in whole or in part, at an
exercise price per Compensation Unit equal to $1.00, at any time during the
period commencing on the Closing Date and ending on the date that is 24 months
following the Closing Date. The Corporation shall execute and deliver to the
Agents at the applicable Closing Time certificates evidencing the Compensation
Options (the Compensation Option Certificates) to which the Agents are
entitled, in a form to be agreed upon by the Agents and the Corporation, acting
reasonably. The Agents acknowledge and agree that the Compensation Options shall
not be exercisable by or on behalf of a person in the United States or a U.S.
Person (as hereinafter defined) and that the Compensation Options and the
securities underlying such Compensation Options will not be registered under the
U.S. Securities Act (as hereinafter defined) or under applicable state
securities laws in the United States. Further, each Agent represents and
warrants, severally but not jointly, that (i) the Compensation Options were not
offered to the Agent in the United States, (ii) the Agent is not U.S. Person,
(iii) the Agent is not acting for the account or benefit of a person in the United States or a U.S.
Person and (iv) the Agent did not execute or deliver this Agreement in the
United States.

      for the Offered Units in the Qualifying Provinces and in those
      jurisdictions outside of Canada as may be agreed upon by the Corporation
      and the Agents, acting reasonably, in connection with the Offering;
      however, it is understood and agreed that the Agents shall have no
      obligation to purchase the Offered Units.

| | (b) | The Corporation agrees that the Agents shall have the
      right to invite one or more investment dealers (each, a Selling
      Firm) to form a selling group to participate in the soliciting of
      offers to purchase the Offered Units. The Agents have the exclusive right
      to control all compensation arrangements between the members of the
      selling group (comprised of such Selling Firms) and the Agents, provided
      that no additional amount shall be payable by the Corporation in respect
      thereof. The Corporation grants all of the rights and benefits of this
      Agreement to any Selling Firm so appointed by the Agents and appoints the
      Agents as trustees of such rights and benefits for such Selling Firms, and
      the Agents hereby accept such trust and agree to hold such rights and
      benefits for and on behalf of such Selling Firms. The Agents shall ensure
      that any Selling Firm appointed pursuant to the provisions of this
      subsection 3(b) or with whom the Agents have a contractual relationship
      with respect to the Offering, if any, agrees with the Agents to comply
      with the covenants and obligations given by the Agents herein, including
      Schedule A hereto.

      promptly, after the execution and delivery of this Agreement, file the
      Final Prospectus in each of the Qualifying Provinces with the Canadian
      Securities Regulators under applicable Securities Laws, and will use its
      best efforts to obtain a Passport Decision Document for the Final
      Prospectus in order to qualify the Offered Units for distribution in each
      of the Qualifying Provinces, as soon as possible, and in any event not
      later than 4:00 pm (Toronto time) on December 13, 2010 (or such other time
      and/or later date as the Corporation and the Lead Agent may agree) and
      until the day on which the distribution of the Offered Units is completed,
      the Corporation will promptly take, or cause to be taken, all additional
      steps and proceedings that may from time to time be required under
      applicable Securities Laws to qualify the distribution of the Offered
      Units in the Qualifying Provinces.

      sale to the public directly and through Selling Firms

| | (b) | The Agents shall: (i) use all commercially reasonable
      efforts to complete and cause each Selling Firm to complete the
      distribution of the Offered Units as soon as reasonably practicable; and
      (ii) promptly notify the Corporation when, in their opinion, the Agents
      and the Selling Firms have ceased distribution of the Offered Units and
      provide a written breakdown of the number of Offered Units distributed in
      each of the Qualifying Provinces where such breakdown is required for the

| | (b) | The Lead Agent, on its own behalf and on behalf of the
      Agents, may exercise the Over-Allotment Option in whole or in part during
      the currency thereof by delivering written notice to the Corporation (the
      Over-Allotment Notice) specifying the number of Additional Units
      and/or Additional Unit Shares and/or Additional Warrants to be issued and
      sold. If the Agents exercise the Over-Allotment Option, the Agents shall
      on the Closing Date for the Over-Allotment Option (the Over- Allotment
      Closing Date), which shall be a date that is not less than two
      Business Days and not more than five Business Days after the date of the
      Over-Allotment Notice (such day to be specified by the Agents in their
      sole discretion), pay to the Corporation the aggregate purchase price for
      the Additional Units and/or Additional Unit Shares and/or Additional
      Warrants by wire transfer, certified cheque or bank draft in Canadian
      currency payable at par in Toronto, Ontario against delivery of one or
      more certificates in definitive form representing the Additional Units,
      registered as the Agents direct. Such Over-Allotment Closing Date may be
      the same as the Closing Date, but not later than 30 days following the
      Closing Date. The applicable terms, conditions and provisions of this
      Agreement (including, without limitation, the provisions of section 10
      relating to closing deliveries) shall apply mutatis mutandisto the
      Closing of the issuance of any Additional Units and/or Additional Unit
      Shares and/or Additional Warrants pursuant to any exercise of the
      Over-Allotment Option.

provided that, in the event and to the
extent that a court of competent jurisdiction in a final judgment from which no
appeal can be made or a regulatory authority in a final ruling from which no
appeal can be made shall determine that such Proceedings or Liabilities resulted
from the gross negligence, fraud or wilful misconduct of the Indemnified Party
claiming indemnity, or any of the Agents or their respective employees,
directors, officers, or representatives, or from a breach by such an Indemnified
Party, or any of the Agents or their respective employees, directors, officers,
or representatives, of this Agreement, this indemnity shall not apply.

| | (b) | The Indemnitor waives any right it may have of first
      requiring an Indemnified Party to proceed against or enforce any other
      right, power, remedy or security or to claim payment from any other person
      before claiming under this indemnity. It is not
necessary for an Indemnified Party to incur expense or make payment
before enforcing such indemnity.

| | (c) | If any Proceeding is brought, instituted or threatened in
      respect of any Indemnified Party which may result in a claim for
      indemnification under this Agreement, such Indemnified Party shall
      promptly after receiving notice thereof notify the Indemnitor, in writing,
      and the Indemnitor shall be entitled (but not required) to assume conduct
      of the defence thereof and retain counsel on behalf of the Indemnified
      Party who is reasonably satisfactory to the Indemnified Party, to
      represent the Indemnified Party in such Proceeding and the Indemnitor
      shall pay the fees and disbursements of such counsel and all other expense
      of the Indemnified Party relating to such Proceeding as incurred. Failure
      to so notify the Indemnitor shall not relieve the Indemnitor from
      liability except and only to the extent that the failure materially
      prejudices the Indemnitor. If the Indemnitor assumes conduct of the
      defence for an Indemnified Party, the Indemnified Party shall fully
      cooperate in the defence including without limitation the provision of
      documents, appropriate officers and employees to give witness statements,
      attend examinations for discovery, make affidavits, meet with counsel,
      testify and divulge all information reasonably required to defend or
      prosecute the Proceedings.
