SHAREHOLDER RIGHTS PLAN AGREEMENT

MEMORANDUM OF AGREEMENT, dated as of May 17, 2013
between Northern Dynasty Minerals Ltd. (the Company), a company
incorporated under the laws of British Columbia and Computershare Investor
Services Inc., a corporation existing under the laws of Canada (the Rights
Agent);

WHEREAS the Board of Directors of the Company, in the
exercise of its fiduciary duties to the Company, has determined that it is
advisable for the Company to adopt a shareholder rights plan (the Rights
Plan) to take effect on the Effective Date (as hereinafter defined) to
prevent, to the extent possible, a creeping takeover of the Company and to
ensure that any offer to acquire shares of the Company is made to all
shareholders and cannot be completed unless shareholders holding at least 50% of
the outstanding shares (other than the offeror and related parties) are
deposited or tendered in acceptance of the offer, to ensure, to the extent
possible, the fair treatment of all shareholders in connection with any
take-over bid for the securities of the Company, and to ensure that the Board of
Directors is provided with sufficient time to evaluate unsolicited take-over
bids and to explore and develop alternatives to maximize shareholder value;

AND WHEREAS in order to implement the adoption of a
shareholder rights plan as established by this Agreement, the board of directors
of the Company has:

(a)           
 authorized the issuance, effective at the close of business (Vancouver
time) on the Effective Date, of one Right (as hereinafter defined) in respect of
each Share (as hereinafter defined) outstanding at the close of business
(Vancouver time) on the Effective Date (the Record Time);

(b)             authorized
the issuance of one Right in respect of each Voting Share (as hereinafter
defined) of the Company issued after the Record Time and prior to the earlier of
the Separation Time (as hereinafter defined) and the Expiration Time (as
hereinafter defined); and

(c)            
authorized the issuance of Rights Certificates (as hereinafter defined) to
holders of Rights pursuant to the terms and subject to the conditions set forth
herein;

AND WHEREAS each Right entitles the holder thereof,
after the Separation Time, to purchase securities of the Company pursuant to the
terms and subject to the conditions set forth herein;

AND WHEREAS the Company desires to appoint the Rights
Agent to act on behalf of the Company and the holders of Rights, and the Rights
Agent is willing to so act, in connection with the issuance, transfer, exchange
and replacement of Rights Certificates, the exercise of Rights and other matters
referred to herein;

NOW THEREFORE, in consideration of the premises and the
respective covenants and agreements set forth herein, and subject to such
covenants and agreements, the parties hereby agree as follows:

THE RIGHTS

**2.1**                        **Issue
of Rights: Legend on Common Share Certificates**

(a)             One
Right shall be issued on the Effective Date in respect of each Common Share
outstanding at the Record Time and one Right shall be issued in respect of each
Common Share issued after the Record Time and prior to the earlier of the
Separation Time and the Expiration Time.

(b)            
Certificates representing Shares which are issued after the Record Time but
prior to the earlier of the Separation Time and the Expiration Time, shall also
evidence one Right for each Share represented thereby until the earlier of the
Separation Time or the Expiration Time and shall have impressed on, printed on,
written on or otherwise affixed to them the following legend:

> Until the earlier of the Separation
>         Time or the Expiration Time (as both terms are defined in the Shareholder Rights
>         Agreement referred to below), this certificate also evidences and entitles the
>         holder hereof to certain Rights as set forth in the Shareholder Rights Plan Agreement
>         dated as of May 17, 2013, as may be amended or supplemented from time to time

>         Agent, the terms of which are incorporated herein by reference and a copy of
>         which is on file at the principal executive offices of the Company. Under
>         certain circumstances set out in the Shareholder Rights Agreement, the rights

>         they are Beneficially Owned by an Acquiring Person as such
>         terms are defined in the Shareholder Rights Agreement, whether currently held by
>         or on behalf of such Person or a subsequent holder) or may be evidenced by
>         separate certificates and no longer evidenced by this certificate. The Company
>         will mail or arrange for the mailing of a copy of the Shareholder Rights

16

---

Certificates representing Shares that are issued and
outstanding at the Record Time shall also evidence one Right for each Share
represented thereby notwithstanding the absence of the foregoing legend, until
the earlier of the Separation Time and the Expiration Time.

**2.2**                        **Initial
Exercise Price; Exercise of Rights; Detachment of Rights**

(a)            
Subject to adjustment as herein set forth, each Right will entitle the holder
thereof, from and after the Separation Time and prior to the Expiration Time, to
purchase one Share for the Exercise Price as at the Business Day immediately
preceding the day of exercise of the Right (which Exercise Price and number of
Shares are subject to adjustment as set forth below). Notwithstanding any other
provision of this Agreement, any Rights held by the Company or any of its
Subsidiaries shall be void.

(b)             Until
the Separation Time,

(i)            
 the Rights shall not be exercisable and no Right may be exercised; and

(ii)             each
Right will be evidenced by the certificate for the associated Voting Share
registered in the name of the holder thereof (which certificate shall also be
deemed to represent a Rights Certificate) and will be transferable only together
with, and will be transferred by a transfer of, such associated Voting
Share.

(c)             From
and after the Separation Time and prior to the Expiration Time:

(i)            
 the Rights shall be exercisable; and

(ii)            
the registration and transfer of Rights shall be separate from and independent
of Voting Shares.

Promptly following the Separation Time,
the Company will prepare or cause to be prepared and the Rights Agent will mail
to each holder of record of Voting Shares as of the Separation Time and, in respect of
each Convertible Security converted into Voting Shares after the Separation Time
and prior to the Expiration Time, promptly after such conversion, the Company
will prepare or cause to be prepared and the Rights Agent will mail to the
holder so converting (other than in either case an Acquiring Person and any
Transferee whose rights are or become null and void pursuant to Section 3.1(b)
and, in respect of any Rights Beneficially Owned by such Acquiring Person or
Transferee which are not held of record by such Acquiring Person or Transferee,
the holder of record of such Rights (a Nominee)), at such holders
address as shown by the records of the Company (the Company hereby agreeing to
furnish copies of such records to the Rights Agent for this purpose):

17

---

(x)             a
Rights Certificate appropriately completed, representing the number of Rights
held by such holder at the Separation Time or at the time of conversion, as
applicable, and having such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any law, rule or regulation or judicial or
administrative order made pursuant thereto or with any rule or regulation of any
self-regulatory organization, stock exchange or quotation system on which the
Rights may from time to time be listed or traded, or to conform to usage; and

(y)            
disclosure statement describing the Rights,

provided that a Nominee shall be sent
the materials provided for in (x) and (y) only in respect of all Shares held of
record by it which are not Beneficially Owned by an Acquiring Person. In order
for the Company to determine whether any Person is holding Shares which are
Beneficially Owned by another Person, the Company may require such first Person
to furnish such information and documentation as the Company deems necessary.

(d)             Rights
may be exercised, in whole or in part, on any Business Day after the Separation
Time and prior to the Expiration Time by submitting to the Rights Agent at its
office in Vancouver, Canada or any other office of the Rights Agent in cities
designated from time to time for that purpose by the Company with the approval
of the Rights Agent:

(i)              
the Rights Certificate evidencing such Rights;

(ii)             
an election to exercise such Rights (an Election to Exercise)
substantially in the form attached to the Rights Certificate appropriately
completed and duly executed by the holder or such holders executors or
administrators or other personal representatives or such holders or their legal
attorney duly appointed by an instrument in writing in form and executed in a
manner satisfactory to the Rights Agent; and

(iii)            
payment by certified cheque, bankers draft, money order or wire transfer
payable to the order of the Rights Agent, of a sum equal to the Exercise Price
multiplied by the number of Rights
being exercised and a sum sufficient to cover any transfer tax or charge which
may be payable in respect of any transfer involved in the transfer or delivery
of Rights Certificates or the issuance or delivery of certificates for Shares in
a name other than that of the holder of the Rights being exercised.

18

---

(e)             Upon
receipt of a Rights Certificate, together with a completed Election to Exercise
executed in accordance with Clause 2.2(d)(ii), which does not indicate that such
Right is null and void as provided by Subsection 3.1(b), and payment as set
forth in Clause 2.2(d)(iii), the Rights Agent (unless otherwise instructed by
the Company in the event that the Company is of the opinion that the Rights
cannot be exercised in accordance with this Agreement) will thereupon as soon as
practicable:

(i)              
requisition from the transfer agent certificates representing the number of such
Shares to be purchased (the Company hereby irrevocably authorizing its transfer
agent to comply with all such requisitions);

(ii)            
 when appropriate, requisition from the Company the amount of cash to be
paid in lieu of issuing fractional Shares;

(iii)             after
receipt of the certificates referred to in Clause 2.2(e)(i), deliver the same to
or upon the order of the registered holder of such Rights Certificates,
registered in such name or names as may be designated by such holder;

(iv)            
when appropriate, after receipt, deliver the cash referred to in Clause
2.2(e)(ii) to or to the order of the registered holder of such Rights
Certificate; and

(v)             
remit to the Company all payments received on the exercise of Rights.

(f)            
In case the holder of any Rights shall exercise less than all the Rights
evidenced by such holders Rights Certificate, a new Rights Certificate
evidencing the Rights remaining unexercised (subject to the provisions of
Subsection 5.5(a)) will be issued by the Rights Agent to such holder or to such
holders duly authorized assigns.

(g)             The
Company covenants and agrees that it will:

(i)              
take all such action as may be necessary and within its power to ensure that all
Shares delivered upon exercise of Rights shall, at the time of delivery of the
certificates for such Shares (subject to payment of the Exercise Price), be duly
and validly authorized, executed, issued and delivered as fully paid and
non-assessable;

(ii)            
take all such action as may be necessary and within its power to comply with the
requirements of the British Columbia Business Corporations Act, the Securities
Act and the securities laws or comparable legislation of each of the provinces
of Canada, and any other applicable law, rule or regulation, in connection with
the issuance and delivery of the Rights Certificates and the issuance of any
Shares upon exercise of Rights;

19

---

(iii)             use
reasonable efforts to cause all Shares issued upon exercise of Rights to be
listed on the stock exchanges and markets on which such Shares were traded
immediately prior to the Separation Time;

(iv)            
pay when due and payable, if applicable, any and all federal, provincial and
municipal transfer taxes and charges (not including any income or capital taxes
of the holder or exercising holder or any liability of the Company to withhold
tax) which may be payable in respect of the original issuance or delivery of the
Rights Certificates, or certificates for Shares to be issued upon exercise of
any Rights, provided that the Company shall not be required to pay any transfer
tax or charge which may be payable in respect of any transfer involved in the
transfer or delivery of Rights Certificates or the issuance or delivery of
certificates for Shares in a name other than that of the holder of the Rights
being transferred or exercised; and

(v)             
after the Separation Time, except as permitted by Sections 5.1 and 5.4, not take
(or permit any Subsidiary to take) any action if at the time such action is
taken it is reasonably foreseeable that such action will diminish substantially
or otherwise eliminate the benefits intended to be afforded by the Rights.

**2.3**                        **Adjustments to Exercise Price; Number of Rights**

The Exercise Price, the number and kind of securities subject
to purchase upon exercise of each Right and the number of Rights outstanding are
subject to adjustment from time to time as provided in this Section 2.3.

(a)            
In the event the Company shall at any time after the Record Time and prior to
the Expiration Time:

(i)            
declare or pay a dividend on Shares payable in Shares or Convertible Securities
in respect thereof other than pursuant to any Dividend Reinvestment Plan;

(ii)             subdivide
or change the then outstanding Shares into a greater number of Shares;

(iii)             consolidate
or change the then outstanding Shares into a smaller number of Shares; or

(iv)            
issue any Shares (or Convertible Securities in respect thereof) in respect of,
in lieu of or in exchange for existing Shares except as otherwise provided in
this Section 2.3,

then the Exercise Price and the number
of Rights outstanding (or, if the payment or effective date therefor shall occur
after the Separation Time, the securities purchasable upon exercise of Rights)
shall be adjusted as of the payment or effective date in the manner set forth
below.

20

---

If the Exercise Price and number of
Rights outstanding are to be adjusted:

(x)             the
Exercise Price in effect after such adjustment will be equal to the Exercise
Price in effect immediately prior to such adjustment divided by the number of
Shares (or other capital stock) (the Expansion Factor) that a holder of
one Share immediately prior to such distribution, subdivision, change,
consolidation or issuance would hold thereafter as a result thereof; and

(y)            
each Right held prior to such adjustment will become that number of Rights equal
to the Expansion Factor,

and the adjusted number of Rights will
be deemed to be distributed among the Shares with respect to which the original
Rights were associated (if they remain outstanding) and the Shares issued in
respect of such dividend, subdivision, change, consolidation or issuance, so
that each such Share (or other capital stock) will have exactly one Right
associated with it.

For greater certainty, if the
securities purchasable upon exercise of Rights are to be adjusted, the
securities purchasable upon exercise of each Right after such adjustment will be
the securities that a holder of the securities purchasable upon exercise of one
Right immediately prior to such dividend, subdivision, change, consolidation or
issuance would hold thereafter as a result of such dividend, subdivision,
change, consolidation or issuance.

If, after the Record Time and prior to
the Expiration Time, the Company shall issue any shares of capital stock other
than Shares in a transaction of a type described in Clause 2.3(a)(i) or (iv),
such shares of capital stock shall be treated herein as nearly equivalent to
Shares as may be practicable and appropriate under the circumstances and the
Company and the Rights Agent agree to amend this Agreement in order to effect
such treatment.

If an event occurs which would require
an adjustment under both this Section 2.3 and Section 3.1, the adjustment
provided for in this Section 2.3 shall be in addition to, and shall be made
prior to, any adjustment required under Section 3.1.

In the event the Company shall at any
time after the Record Time and prior to the Separation Time issue any Shares
otherwise than in a transaction referred to in this Subsection 2.3(a), each such
Share so issued shall automatically have one new Right associated with it, which
Right shall be evidenced by the certificate representing such associated Share.

(b)            
In the event the Company shall at any time after the Record Time and prior to
the Separation Time fix a record date for the issuance of rights, options or
warrants to all holders of Shares entitling them (for a period expiring within
45 calendar days after such record date) to subscribe for or purchase Shares (or
Convertible Securities in respect of Shares) at a price per Share (or, in the
case of a Convertible Security, having a conversion, exchange or exercise price
per share, including the price required to be paid to purchase such Convertible
Security) less than the Market Price per Share on such record date, the Exercise
Price to be in effect after such record date shall be determined by multiplying the Exercise Price in
effect immediately prior to such record date by a fraction:

21

---

(i)             
the numerator of which shall be the number of Shares outstanding on such record
date plus the number of Shares that the aggregate offering price of the total
number of Shares so to be offered (and/or the aggregate initial conversion,
exchange or exercise price of the Convertible Securities, including the price
required to be paid to purchase such Convertible Securities) would purchase at
such Market Price per Share; and

(ii)             the
denominator of which shall be the number of Shares outstanding on such record
date plus the number of additional Shares to be offered for subscription or
purchase (or into which the Convertible Securities so to be offered are
initially convertible, exchangeable or exercisable).

In case such subscription price may be
paid by delivery of consideration, part or all of which may be in a form other
than cash, the value of such consideration shall be as determined in good faith
by the Board of Directors, whose determination shall be described in a statement
filed with the Rights Agent and shall be binding on the Rights Agent and the
holders of Rights. Such adjustment shall be made successively whenever such a
record date is fixed, and in the event that such rights, options or warrants are
not so issued, or if issued, are not exercised prior to the expiration thereof,
the Exercise Price shall be readjusted to the Exercise Price which would then be
in effect if such record date had not been fixed, or to the Exercise Price which
would be in effect based upon the number of Shares (or securities convertible
into, or exchangeable or exercisable for Shares) actually issued upon the
exercise of such rights, options or warrants, as the case may be.

For purposes of this Agreement, the
granting of the right to purchase Shares (whether from treasury or otherwise)
pursuant to any Dividend Reinvestment Plan or any employee benefit plan, stock
option plan or any similar plan shall be deemed not to constitute an issue of
rights, options or warrants by the Company; provided, however, that, in the case
of any Dividend Reinvestment Plan or share purchase plan, the right to purchase
Shares is at a price per Share of not less than 90% of the current market price
per share (determined as provided in such plans) of the Shares.

(c)            
In the event the Company shall at any time after the Record Time and prior to
the Separation Time fix a record date for the making of a distribution to all
holders of Shares (including any such distribution made in connection with a
merger or amalgamation) of evidences of indebtedness, cash (other than an annual
cash dividend or a dividend paid in Common Shares, but including any dividend
payable in securities other than Common Shares), assets or rights, options or
warrants (excluding rights, options or warrants expiring within 45 calendar days
after such record date) to purchase Shares or Convertible Securities in respect
of Shares, the Exercise Price in effect after such record date shall be equal to
the Exercise Price in effect immediately prior to such record date less the fair
market value (as determined in good faith by the Board of Directors) of the portion of the evidences of
indebtedness, cash, assets, rights, options or warrants so to be distributed
applicable to the securities purchasable upon exercise of one Right.

22

---

(d)            
Notwithstanding anything herein to the contrary, no adjustment in the Exercise
Price shall be required unless such adjustment would require an increase or
decrease of at least one per cent in the Exercise Price; provided, however, that
any adjustments which by reason of this Subsection 2.3(d) are not required to be
made shall be carried forward and taken into account in any subsequent
adjustment. All calculations under Section 2.3 shall be made to the nearest cent
or to the nearest ten-thousandth of a Share. Any adjustment required by Section
2.3 shall be made as of:

(i)             
the payment or effective date for the applicable dividend, subdivision, change,
combination or issuance, in the case of an adjustment made pursuant to
Subsection 2.3(a); or

(ii)            
the record date for the applicable dividend or distribution, in the case of an
adjustment made pursuant to Subsection 2.3(b) or (c), subject to readjustment to
reverse the same if such dividend or distribution shall not be made.

(e)            
In the event the Company shall at any time after the Record Time and prior to
the Separation Time issue any shares (other than Shares), or rights, options or
warrants to subscribe for or purchase any such shares, or securities convertible
into or exchangeable for any such shares, in a transaction referred to in Clause
2.3(a)(i) or (iv) or Subsections 2.3(b) or (c), if the Board of Directors acting
in good faith determines that the adjustments contemplated by Subsections
2.3(a), (b) and (c) in connection with such transaction will not appropriately
protect the interests of the holders of Rights, the Board of Directors may
determine what other adjustments to the Exercise Price, number of Rights and/or
securities purchasable upon exercise of Rights would be appropriate and,
notwithstanding Subsections 2.3(a), (b) and (c), such adjustments, rather than
the adjustments contemplated by Subsections 2.3(a), (b) and (c), shall be made.
Subject to Subsection 5.4(b) and (c), the Company and the Rights Agent may, with
the prior approval of the holders of the Shares amend this Agreement as
appropriate to provide for such adjustments.

(f)             Each
Right originally issued by the Company subsequent to any adjustment made to the
Exercise Price hereunder shall evidence the right to purchase, at the adjusted
Exercise Price, the number of Shares purchasable from time to time hereunder
upon exercise of a Right immediately prior to such issue, all subject to further
adjustment as provided herein.

(g)            
Irrespective of any adjustment or change in the Exercise Price or the number of
Shares issuable upon the exercise of the Rights, the Rights Certificates
theretofore and thereafter issued may continue to express the Exercise Price per
Share and the number of Shares which were expressed in the initial Rights
Certificates issued hereunder.

(h)            
In any case in which this Section 2.3 shall require that an adjustment in the
Exercise Price be made effective as of a record date for a specified event, the
Company may elect to defer until the occurrence
of such event the issuance to the holder of any Right exercised after such
record date the number of Shares and other securities of the Company, if any,
issuable upon such exercise over and above the number of Shares and other
securities of the Company, if any, issuable upon such exercise on the basis of
the Exercise Price in effect prior to such adjustment; provided, however, that
the Company shall deliver to such holder an appropriate instrument evidencing
such holders right to receive such additional shares (fractional or otherwise)
or other securities upon the occurrence of the event requiring such adjustment.

23

---

(i)             Notwithstanding
anything contained in this Section 2.3 to the contrary, the Company shall be
entitled to make such reductions in the Exercise Price, in addition to those
adjustments expressly required by this Section 2.3, as and to the extent that in
their good faith judgment the Board of Directors shall determine to be
advisable, in order that any:

(i)            
  consolidation or subdivision of Shares;

(ii)             
 issuance (wholly or in part for cash) of Shares or securities that by
their terms are convertible into or exchangeable for Shares;

(iii)             stock
dividends; or

(iv)            
issuance of rights, options or warrants referred to in this Section 2.3,

hereafter made by the Company to
holders of its Shares, subject to applicable taxation laws, shall not be taxable
to such shareholders or shall subject such shareholders to a lesser amount of
tax.

(j)             Whenever
an adjustment to the Exercise Price is made pursuant to this Section 2.3, the
Company shall:

(i)            
 promptly prepare a certificate setting forth such adjustment and a brief
statement of the facts accounting for such adjustment; and

(ii)            promptly
file with the Rights Agent and with each transfer agent for the Shares a copy of
such certificate and mail a brief summary thereof to each holder of Rights who
requests a copy;

Failure to file such certificate or to
cause such notice to be given as aforesaid, or any defect therein, shall not
affect the validity of any such adjustment or change.

**2.4**                        **Date
on Which Exercise Is Effective**

Each Person in whose name any certificate for Shares or other
securities, if applicable, is issued upon the exercise of Rights shall for all
purposes be deemed to have become the absolute holder of record of the Shares or
other securities, if applicable, represented thereon, and such certificate shall
be dated the date upon which the Rights Certificate evidencing such Rights was
duly surrendered in accordance with Subsection 2.2(d) (together with a duly
completed Election to Exercise) and payment of the Exercise Price for such Rights
(and any applicable transfer taxes and other governmental charges payable by the
exercising holder hereunder) was made; provided, however, that if the date of
such surrender and payment is a date upon which the Share transfer books of the
Company are closed, such Person shall be deemed to have become the record holder
of such Shares on, and such certificate shall be dated, the next succeeding
Business Day on which the Share transfer books of the Company are open.

24

**2.5**                        **Execution,
Authentication, Delivery and Dating of Rights Certificates**

(a)             The
Rights Certificates shall be executed on behalf of the Company by any of its
Chairman of the Board, President, Chief Executive Officer and Chief Financial
Officer. The signature of any of these officers on the Rights Certificates may
be manual or facsimile. Rights Certificates bearing the manual or facsimile
signatures of individuals who were at any time the proper officers of the
Company shall bind the Company, notwithstanding that such individuals or any of
them have ceased to hold such offices either before or after the
countersignature and delivery of such Rights Certificates.

(b)             Promptly
after the Company learns of the Separation Time, the Company will notify the
Rights Agent of such Separation Time and will deliver Rights Certificates
executed by the Company to the Rights Agent for countersignature, and the Rights
Agent shall countersign (manually or by facsimile signature in a manner
satisfactory to the Company) and send such Rights Certificates to the holders of
the Rights pursuant to Subsection 2.2(c) hereof. No Rights Certificate shall be
valid for any purpose until countersigned by the Rights Agent as aforesaid.

(c)             Each
Rights Certificate shall be dated the date of countersignature thereof.

**2.6**                        **Registration, Transfer and Exchange**

(a)            
The Company will cause to be kept a register (the Rights Register) in
which, subject to such reasonable regulations as it may prescribe, the Company
will provide for the registration and transfer of Rights. The Rights Agent, at
its office in the City of Vancouver, is hereby appointed registrar for the
Rights (the Rights Registrar) for the purpose of maintaining the Rights
Register for the Company and registering Rights and transfers of Rights as
herein provided and the Rights Agent hereby accepts such appointment. In the
event that the Rights Agent shall cease to be the Rights Registrar, the Rights
Agent will have the right to examine the Rights Register at all reasonable
times.

After the Separation Time and prior to
the Expiration Time, upon surrender for registration of transfer or exchange of
any Rights Certificate, and subject to the provisions of Subsection 2.6(c), the
Company will execute, and the Rights Agent will countersign and deliver, in the
name of the holder or the designated transferee or transferees, as required
pursuant to the holders instructions, one or more new Rights Certificates
evidencing the same aggregate number of Rights as did the Rights Certificates so
surrendered.

(b)             All
Rights issued upon any registration of transfer or exchange of Rights
Certificates shall be the valid obligations of the Company, and such Rights
shall be entitled to the same benefits under
this Agreement as the Rights surrendered upon such registration of transfer or
exchange.

25

---

(c)            
Every Rights Certificate surrendered for registration of transfer or exchange
shall be duly endorsed, or be accompanied by a written instrument of transfer in
form satisfactory to the Company or the Rights Agent, as the case may be, duly
executed by the holder thereof or such holders attorney duly authorized in
writing. As a condition to the issuance of any new Rights Certificate under this
Section 2.6, the Company may require the payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the reasonable fees and expenses of the Rights
Agent) connected therewith.

**2.7**                        **Mutilated, Destroyed, Lost and Stolen Rights Certificates**

(a)            
If any mutilated Rights Certificate is surrendered to the Rights Agent prior to
the Expiration Time, the Company shall execute and the Rights Agent shall
countersign and deliver in exchange therefor a new Rights Certificate evidencing
the same number of Rights as did the Rights Certificate so surrendered.

(b)            
If there shall be delivered to the Company and the Rights Agent prior to the
Expiration Time:

(i)             
evidence to their reasonable satisfaction of the destruction, loss or theft of
any Rights Certificate; and

(ii)             such
security or indemnity as may be reasonably required by them to save each of them
and any of their agents harmless,

then, in the absence of notice to the
Company or the Rights Agent that such Rights Certificate has been acquired by a
bona fide purchaser, the Company shall execute and upon the Companys request
the Rights Agent shall countersign and deliver, in lieu of any such destroyed,
lost or stolen Rights Certificate, a new Rights Certificate evidencing the same
number of Rights as did the Rights Certificate so destroyed, lost or stolen.

(c)             As
a condition to the issuance of any new Rights Certificate under this Section
2.7, the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the reasonable fees and expenses of the Rights Agent)
connected therewith.

(d)            
Every new Rights Certificate issued pursuant to this Section 2.7 in lieu of any
destroyed, lost or stolen Rights Certificate shall evidence the contractual
obligation of the Company, whether or not the destroyed, lost or stolen Rights
Certificate shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of this Agreement equally and proportionately with any and all
other Rights duly issued hereunder.

26

---

**2.8**                        **Persons
Deemed Owners of Rights**

The Company, the Rights Agent and any agent of the Company or
the Rights Agent may deem and treat the Person in whose name a Rights
Certificate (or, prior to the Separation Time, the associated Share certificate)
is registered as the absolute owner thereof and of the Rights evidenced thereby
for all purposes whatsoever. As used in this Agreement, unless the context
otherwise requires, the term holder of any Right shall mean the
registered holder of such Right (or, prior to the Separation Time, of the
associated Share).

**2.9**                        **Delivery
and Cancellation of Certificates**

All Rights Certificates surrendered upon exercise or for
redemption, registration of transfer or exchange shall, if surrendered to any
Person other than the Rights Agent, be delivered to the Rights Agent and, in any
case, shall be promptly cancelled by the Rights Agent. The Company may at any
time deliver to the Rights Agent for cancellation any Rights Certificates
previously countersigned and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Rights Certificates so delivered
shall be promptly cancelled by the Rights Agent. No Rights Certificate shall be
countersigned in lieu of or in exchange for any Rights Certificates cancelled as
provided in this Section 2.9, except as expressly permitted by this Agreement.
The Rights Agent shall, subject to applicable laws, destroy all cancelled Rights
Certificates and deliver a certificate of destruction to the Company.

**2.10**                     **Agreement
of Rights Holders**

Every holder of Rights, by accepting the same, consents and
agrees with the Company and the Rights Agent and with every other holder of
Rights:

(a)             to
be bound by and subject to the provisions of this Agreement, as amended from
time to time in accordance with the terms hereof, in respect of all Rights held;

(b)             that
prior to the Separation Time, each Right will be transferable only together
with, and will be transferred by a transfer of, the associated Voting Share
certificate representing such Right;

(c)            
that after the Separation Time, the Rights Certificates will be transferable
only on the Rights Register as provided herein;

(d)            
that prior to due presentment of a Rights Certificate (or, prior to the
Separation Time, the associated Voting Share certificate) for registration of
transfer, the Company, the Rights Agent and any agent of the Company or the
Rights Agent may deem and treat the Person in whose name the Rights Certificate
(or, prior to the Separation Time, the associated Voting Share certificate) is
registered as the absolute owner thereof and of the Rights evidenced thereby
(notwithstanding any notations of ownership or writing on such Rights
Certificate or the associated Voting Share certificate made by anyone other than
the Company or the Rights Agent) for all purposes whatsoever, and neither the
Company nor the Rights Agent shall be affected by any notice to the contrary;

27

---

(e)            
that such holder of Rights has waived his right to receive any fractional Rights
or any fractional shares or other securities upon exercise of a Right (except as
provided herein);

(f)            
that, subject to the provisions of Section 5.4, without the approval of any
holder of Rights or Voting Shares and upon the sole authority of the Board of
Directors, acting in good faith, this Agreement may be supplemented or amended
from time to time pursuant to and as provided herein; and

(g)             that
notwithstanding anything in this Agreement to the contrary, neither the Company
nor the Rights Agent shall have any liability to any holder of a Right or any
other Person as a result of its inability to perform any of its obligations
under this Agreement by reason of preliminary or permanent injunctions or other
order, decree or ruling issued by a court of competent jurisdiction or by a
governmental, regulatory or administrative agency or commission, or any statute,
rule, regulations or executive order promulgated or enacted by any governmental
authority prohibiting or otherwise restraining performance of such obligation.

**2.11**                     **Rights
Certificate Holder Not Deemed a Shareholder**

No holder, as such, of any Rights or Rights Certificate shall
be entitled to vote, receive dividends or be deemed for any purpose whatsoever
the holder of any Share or any other share or security of the Company which may
at any time be issuable on the exercise of the Rights represented thereby, nor
shall anything contained herein or in any Rights Certificate be construed or
deemed or confer upon the holder of any Right or Rights Certificate, as such,
any right, title, benefit or privilege of a holder of Shares or any other shares
or securities of the Company or any right to vote at any meeting of shareholders
of the Company whether for the election of directors or otherwise or upon any
matter submitted to holders of Shares or any other shares of the Company at any
meeting thereof, or to give or withhold consent to any action of the Company, or
to receive notice of any meeting or other action affecting any holder of Shares
or any other shares of the Company except as expressly provided herein, or to
receive dividends, distributions or subscription rights, or otherwise, until the
Right or Rights evidenced by Rights Certificates shall have been duly exercised
in accordance with the terms and provisions hereof.

ARTICLE 3

ADJUSTMENTS TO THE RIGHTS

**3.1**                        **Flip-in Event**

(a)            
Subject to Subsection 3.1(b) and Section 5.1, in the event that prior to the
Expiration Time a Flip-in Event shall occur, each Right shall constitute,
effective at the close of business on the tenth Trading Day after the Share
Acquisition Date, the right to purchase from the Company, upon exercise thereof
in accordance with the terms hereof, that number of Shares having an aggregate
Market Price on the date of consummation or occurrence of such Flip-in Event
equal to twice the Exercise Price for an amount in cash equal to the Exercise
Price (such right to be appropriately adjusted in a manner analogous to the applicable adjustment provided
for in Section 2.3 in the event that after such consummation or occurrence, an
event of a type analogous to any of the events described in Section 2.3 shall
have occurred).

28

---

(b)            
Notwithstanding anything in this Agreement to the contrary, upon the occurrence
of any Flip-in Event, any Rights that are or were Beneficially Owned on or after
the earlier of the Separation Time or the Share Acquisition Date by:

(i)             
an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any
other Person acting jointly or in concert with an Acquiring Person or any
Affiliate or Associate of such other Person); or

(ii)            
a transferee or other successor in title, directly or indirectly, (a
Transferee) of Rights held by an Acquiring Person (or any Affiliate or
Associate of an Acquiring Person or any other Person acting jointly or in
concert with an Acquiring Person or any Affiliate or Associate of such other
Person), where such Transferee becomes a transferee concurrently with or
subsequent to the Acquiring Person becoming such in a transfer that the Board of
Directors acting in good faith has determined is part of a plan, arrangement or
scheme of an Acquiring Person (or any Affiliate or Associate of an Acquiring
Person or any other Person acting jointly or in concert with an Acquiring Person
or any Affiliate or Associate of such other Person), that has the purpose or
effect of avoiding Clause 3.1(b)(i),

shall become null and void without any
further action, and any holder of such Rights (including any Transferee) shall
thereafter have no right to exercise such Rights under any provision of this
Agreement and further shall thereafter not have any other rights whatsoever with
respect to such Rights, whether under any provision of this Agreement or
otherwise. The holder of any Rights represented by a Rights Certificate which is
submitted to the Rights Agent upon exercise or for registration or transfer or
exchange which does not contain the necessary certifications set forth in the
Rights Certificate establishing that such Rights are not null and void under
this Clause 3.1(b) shall be deemed to be an Acquiring Person for the purposes of
this Clause 3.1 and such Rights shall become null and void.

(c)            
From and after the Separation Time, the Company shall do all such acts and
things as shall be necessary and within its power to ensure compliance with the
provisions of this Section 3.1, including without limitation, all such acts and
things as may be required to satisfy the requirements of the British Columbia
Business Corporations Act, the Securities Act and the securities laws or
comparable legislation of each of the provinces of Canada in respect of the
issue of Shares upon the exercise of Rights in accordance with this Agreement.

(d)             Any
Rights Certificate that represents Rights Beneficially Owned by a Person
described in either Clause 3.1(b)(i) or (ii) or transferred to any nominee of
any such Person, and any Rights Certificate issued upon transfer, exchange,
replacement or adjustment of any other Rights
Certificate referred to in this sentence, shall contain the following legend:

29

---

> The Rights represented by this Rights Certificate were issued
>         to a Person who was an Acquiring Person or an Affiliate or an Associate of an
>         Acquiring Person (as such terms are defined in the Shareholder Rights Agreement)
>         or a Person who was acting jointly or in concert with an Acquiring Person or an
>         Affiliate or Associate of such Person. This Rights Certificate and the Rights
>         represented hereby are void or shall become void in the circumstances specified
>         in Subsection 3.1(b) of the Shareholder Rights Agreement.

provided, however, that the Rights
Agent shall not be under any responsibility to ascertain the existence of facts
that would require the imposition of such legend but shall impose such legend
only if instructed to do so by the Company in writing or if a holder fails to
certify upon transfer or exchange in the space provided on the Rights
Certificate that such holder is not a Person described in such legend and
provided further that the fact that such legend does not appear on a certificate
is not determinative of whether any Rights represented thereby are void under
this Section.

ARTICLE 4

THE RIGHTS AGENT

**4.1**                        **General**

(a)            
The Company hereby appoints the Rights Agent to act as agent for the Company in
accordance with the terms and conditions hereof, and the Rights Agent hereby
accepts such appointment. The Company may from time to time appoint such
co-Rights Agents (Co-Rights Agents) as it may deem necessary or
desirable. In the event the Company appoints one or more Co-Rights Agents, the
respective duties of the Rights Agent and Co-Rights Agents shall be as the
Company may determine with the approval of the Rights Agent and the Co-Rights
Agent. The Company agrees to pay to the Rights Agent reasonable compensation for
all services rendered by it hereunder and, from time to time, on demand of the
Rights Agent, its reasonable expenses and counsel fees and other disbursements
incurred in the administration and execution of this Agreement and the exercise
and performance of its duties hereunder (including the fees and disbursements of
any expert or advisor retained by the Rights Agent). The Company also agrees to
indemnify the Rights Agent, and its officers, directors, employees and agents
for, and to hold it and them harmless against, any loss, liability or expense,
incurred without negligence, bad faith or wilful misconduct on the part of the
Rights Agent or such persons, for anything done or omitted by the Rights Agent
or such persons in connection with the acceptance and administration of this
Agreement, including legal costs and expenses, which right to indemnification
will survive the termination of this Agreement and the resignation or removal of
the Rights Agent.

30

---

(b)             The
Rights Agent shall be protected and shall incur no liability for or in respect
of any action taken, suffered or omitted by it in connection with its
administration of this Agreement in reliance upon any certificate for Shares,
Rights Certificate, certificate for other securities of the Company, instrument
of assignment or transfer, power of attorney, endorsement, affidavit, letter,
notice, direction, consent, certificate, statement, or other paper or document
believed by it to be genuine and to be signed, executed and, where necessary,
verified or acknowledged, by the proper Person or Persons.

(c)             The
Company shall inform the Rights Agent in a reasonably timely manner of events
which may materially affect the administration of this Agreement by the Rights
Agent and, at any time upon request, shall provide to the Rights Agent an
incumbency certificate certifying the then current officers of the Company.

(d)             No
provision contained in this Agreement shall require the Rights Agent to expend
or risk its own funds or otherwise incur financial liability in the performance
of any of its duties or in the exercise of any of its rights or powers.

**4.2**                        **Merger,
Amalgamation or Consolidation or Change of Name of Rights Agent**

(a)             Any
Company into which the Rights Agent may be merged or amalgamated or with which
it may be consolidated, or any Company resulting from any merger, amalgamation,
statutory arrangement or consolidation to which the Rights Agent is a party, or
any Company succeeding to the shareholder or stockholder services business of
the Rights Agent, will be the successor to the Rights Agent under this Agreement
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, provided that such Company would be eligible for
appointment as a successor Rights Agent under the provisions of Section 4.4
hereof. In case at the time such successor Rights Agent succeeds to the agency
created by this Agreement any of the Rights Certificates have been countersigned
but not delivered, any successor Rights Agent may adopt the countersignature of
the predecessor Rights Agent and deliver such Rights Certificates so
countersigned; and in case at that time any of the Rights have not been
countersigned, any successor Rights Agent may countersign such Rights
Certificates in the name of the predecessor Rights Agent or in the name of the
successor Rights Agent; and in all such cases such Rights Certificates will have
the full force provided in the Rights Certificates and in this Agreement.

(b)            
In case at any time the name of the Rights Agent is changed and at such time any
of the Rights Certificates shall have been countersigned but not delivered, the
Rights Agent may adopt the countersignature under its prior name and deliver
Rights Certificates so countersigned; and in case at that time any of the Rights
Certificates shall not have been countersigned, the Rights Agent may countersign
such Rights Certificates either in its prior name or in its changed name; and in
all such cases such Rights Certificates shall have the full force provided in
the Rights Certificates and in this Agreement.

31

---

**4.3**                        **Duties
of Rights Agent**

The Rights Agent undertakes the duties and obligations imposed
by this Agreement upon the following terms and conditions, all of which the
Company and the holders of certificates for Shares and the holders of Rights
Certificates, by their acceptance thereof, shall be bound:

(a)             the
Rights Agent may retain and consult with legal counsel (who may be legal counsel
for the Company) and the opinion of such counsel will be full and complete
authorization and protection to the Rights Agent as to any action taken or
omitted by it in good faith and in accordance with such opinion and the Rights
Agent may also consult with such other experts as the Rights Agent may
reasonably consider necessary or appropriate to properly carry out the duties
and obligations imposed under this Agreement (at the expense of the Company) and
the Rights Agent shall be entitled to act and rely in good faith on the advice
of any such expert;

(b)             whenever
in the performance of its duties under this Agreement, the Rights Agent deems it
necessary or desirable that any fact or matter be proved or established by the
Company prior to taking or suffering any action hereunder, such fact or matter
(unless other evidence in respect thereof be herein specifically prescribed) may
be deemed to be conclusively proved and established by a certificate signed by a
Person believed by the Rights Agent to be the Chairman of the Board, President,
Chief Executive Officer or Chief Financial Officer of the Company and delivered
to the Rights Agent; and such certificate will be full authorization to the
Rights Agent for any action taken or suffered in good faith by it under the
provisions of this Agreement in reliance upon such certificate;

(c)             the
Rights Agent will be liable hereunder only for its own negligence, bad faith or
willful misconduct;

(d)            
the Rights Agent will not be liable for or by reason of any of the statements of
fact or recitals contained in this Agreement or in the certificates for Shares,
or the Rights Certificates (except its countersignature thereof) or be required
to verify the same, but all such statements and recitals are and will be deemed
to have been made by the Company only;

(e)             the
Rights Agent will not be under any responsibility in respect of the validity of
this Agreement or the execution and delivery hereof (except the due
authorization, execution and delivery hereof by the Rights Agent) or in respect
of the validity or execution of any certificate for a Share or Rights
Certificate (except its countersignature thereof); nor will it be responsible
for any breach by the Company of any covenant or condition contained in this
Agreement or in any Rights Certificate; nor will it be responsible for any
change in the exercisability of the Rights (including the Rights becoming void
pursuant to Subsection 3.1(b) hereof) or any adjustment required under the
provisions of Section 2.3 hereof or responsible for the manner, method or amount
of any such adjustment or the ascertaining of the existence of facts that would
require any such adjustment (except with respect to the exercise of Rights after
receipt of the certificate contemplated by Section 2.3 describing any such
adjustment); nor will it by any act hereunder be deemed to make any
representation or warranty as to the authorization of any Shares to be issued
pursuant to this Agreement or any Rights or as to whether any Shares will, when
issued, be duly and validly authorized, executed, issued and delivered and fully
paid and non-assessable;

32

---

(f)            
the Company agrees that it will perform, execute, acknowledge and deliver or
cause to be performed, executed, acknowledged and delivered all such further and
other acts, instruments and assurances as may reasonably be required by the
Rights Agent for the carrying out or performing by the Rights Agent of the
provisions of this Agreement;

(g)             the
Rights Agent is hereby authorized and directed to accept instructions in writing
with respect to the performance of its duties hereunder from any individual
believed by the Rights Agent to be the Chairman of the Board, President, Chief
Executive Officer or Chief Financial Officer of the Company, and to apply to
such individuals for advice or instructions in connection with its duties, and
it shall not be liable for any action taken or suffered by it in good faith in
accordance with instructions of any such individual. It is understood that
instructions to the Rights Agent shall, except where circumstances make it
impractical or the Rights Agent otherwise agrees, be given in writing and, where
not in writing, such instructions shall be confirmed in writing as soon as
practicable after the giving of such instructions;

(h)             the
Rights Agent and any shareholder or stockholder, director, officer or employee
of the Rights Agent may buy, sell or deal in Shares, Rights or other securities
of the Company or become pecuniarily interested in any transaction in which the
Company may be interested, or contract with or lend money to the Company or
otherwise act as fully and freely as though it were not Rights Agent under this
Agreement. Nothing herein shall preclude the Rights Agent from acting in any
other capacity for the Company or for any other legal entity; and

(i)             the
Rights Agent may execute and exercise any of the rights or powers hereby vested
in it or perform any duty hereunder either itself or by or through its attorneys
or agents, and the Rights Agent will not be answerable or accountable for any
act, default, neglect or misconduct of any such attorneys or agents or for any
loss to the Company resulting from any such act, default, neglect or misconduct,
provided reasonable care was exercised in the selection and continued employment
thereof.

**4.4**                        **Change
of Rights Agent**

The Rights Agent may resign and be discharged from its duties
under this Agreement upon 60 days notice (or such lesser notice as is acceptable
to the Company) in writing mailed to the Company and to each transfer agent of
Shares by registered or certified mail and to the holders of Rights in
accordance with Section 5.9. The Company may remove the Rights Agent upon 30
days notice in writing, mailed to the Rights Agent and to each transfer agent of
the Shares by registered or certified mail and to the holders of Rights in
accordance with Section 5.9. If the Rights Agent should resign or be removed or
otherwise become incapable of acting, the Company will appoint a successor to
the Rights Agent. If the Company fails to make such appointment within a period
of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent, then by prior written notice to the Company the
resigning Rights Agent or the holder of any Rights (which holder shall, with
such notice, submit such holders Rights Certificate, if any, for inspection by
the Company), may apply, at the Companys expense, to any court of competent
jurisdiction for the appointment of a new Rights Agent. Any successor Rights
Agent, whether appointed by the Company or by such a court, shall be a Company
incorporated under the laws of Canada or a province thereof authorized to carry
on the business of a trust company in the Province of British Columbia. After
appointment, the successor Rights Agent will be vested with the same powers,
rights, duties and responsibilities as if it had been originally named as Rights
Agent without further act or deed; but the predecessor Rights Agent shall, upon
payment in full of any outstanding amounts owing by the Company to the Rights
Agent under this Agreement, deliver and transfer to the successor Rights Agent
any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company will file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Shares, and mail a notice thereof in writing to the holders of the Rights in
accordance with Section 5.9. Failure to give any notice provided for in this
Section 4.4, however, or any defect therein, shall not affect the legality or
validity of the resignation or removal of the Rights Agent or the appointment of
any successor Rights Agent, as the case may be.

ARTICLE 5

MISCELLANEOUS

**5.1**                        **Redemption and Waiver**

(a)            
The Board of Directors acting in good faith may, with the prior approval of the
holders of Voting Shares or of the holders of Rights given in accordance with
Section 5.1(i) or (j), as the case may be, at any time prior to the occurrence
of a Flip-in Event as to which the application of Section 3.1 has not been
waived pursuant to the provisions of this Section 5.1, elect to redeem all but
not less than all of the then outstanding Rights at a redemption price of
$0.00001 per Right appropriately adjusted in a manner analogous to the
applicable adjustment provided for in Section 2.3 in the event that an event of
the type analogous to any of the events described in Section 2.3 shall have
occurred (such redemption price being herein referred to as the Redemption
Price).

(b)            
The Board of Directors acting in good faith may, with the prior approval of the
holders of Voting Shares given in accordance with Section 5.1(i), determine, at
any time prior to the occurrence of a Flip-in Event as to which the application
of Section 3.1 has not been waived pursuant to this Section 5.1, if such Flip-in
Event would occur by reason of an acquisition of Voting Shares otherwise than
pursuant to a Take-over Bid made by means of a take-over bid circular to all
holders of record of Voting Shares and otherwise than in the circumstances set
forth in Subsection 5.1(d), to waive the application of Section 3.1 to such
Flip-in Event. In the event that the Board of Directors proposes such a waiver,
the Board of Directors shall extend the Separation Time to a date subsequent to
and not more than ten Business Days
following the meeting of shareholders called to approve such waiver.

34

---

(c)             The
Board of Directors acting in good faith may, until the occurrence of a Flip-in
Event and upon prior written notice delivered to the Rights Agent, determine to
waive the application of Section 3.1 to such particular Flip-in Event, provided
that the Flip-in Event would occur by reason of a Take-over Bid made by way of
take-over bid circular sent to all holders of Voting Shares (which for greater
certainty shall not include the circumstances described in Subsection 5.1(d));
provided that if the Board of Directors waives the application of Section 3.1 to
a particular Flip-in Event pursuant to this Subsection 5.1(c), the Board of
Directors shall be deemed to have waived the application of Section 3.1 to any
other Flip-in Event subsequently occurring by reason of any Take-over Bid which
is made by means of a take-over bid circular to all holders of Voting Shares
prior to the expiry of any Take-over Bid in respect of which a waiver is, or is
deemed to have been, granted under this Subsection 5.1(c).

(d)             Notwithstanding
the provisions of Subsections 5.1(b) and (c) hereof, the Board of Directors may
waive the application of Section 3.1 in respect of the occurrence of any Flip-in
Event if the Board of Directors has determined within ten Trading Days following
a Stock Acquisition Date that a Person became an Acquiring Person by
inadvertence and without any intention to become, or knowledge that it would
become, an Acquiring Person under this Agreement, and in the event such waiver
is granted by the Board of Directors, such Stock Acquisition Date shall be
deemed not to have occurred. Any such waiver pursuant to this Subsection 5.1(d)
must be on the condition that such Person, within 14 days after the foregoing
determination by the Board of Directors or such earlier or later date as the
Board of Directors may determine (the Disposition Date), has reduced
its Beneficial Ownership of Voting Shares such that the Person is no longer an
Acquiring Person. If the Person remains an Acquiring Person at the close of
business on the Disposition Date, the Disposition Date shall be deemed to be the
date of occurrence of a further Stock Acquisition Date and Section 3.1 shall
apply thereto.

(e)             The
Board of Directors, shall, without further formality, be deemed to have elected
to redeem the Rights at the Redemption Price on the date that a Person which has
made a Permitted Bid, a Competing Permitted Bid or a Take-Over Bid in respect of
which the Board of Directors has waived, or is deemed to have waived, pursuant
to Subsection 5.1(c) the application of Section 3.1, takes up and pays for
Voting Shares in connection with such Permitted Bid, Competing Permitted Bid or
Take-over bid, as the case may be.

(f)            
Where a Take-over Bid that is not a Permitted Bid Acquisition is withdrawn or
otherwise terminated after the Separation Time has occurred and prior to the
occurrence of a Flip-in Event, the Board of Directors may elect to redeem all
the outstanding Rights at the Redemption Price. Upon the Rights being redeemed
pursuant to this Subsection 5.1(f), all the provisions of this Agreement shall
continue to apply as if the Separation Time had not occurred and Rights
Certificates representing the number of Rights held by each holder of record of
Shares as of the Separation Time had not been mailed to each such holder and for all purposes of
this Agreement the Separation Time shall be deemed not to have occurred.

35

---

(g)            
If the Board of Directors elects or is deemed to have elected to redeem the
Rights, and, in circumstances in which Subsection 5.1(a) is applicable, such
redemption is approved by the holders of Voting Shares or the holders of Rights
in accordance with Subsection 5.1(i) or (j), as the case may be, the right to
exercise the Rights, will thereupon, without further action and without notice,
terminate and the only right thereafter of the holders of Rights shall be to
receive the Redemption Price.

(h)            
Within 10 Business Days after the Board of Directors elects or is deemed to
elect, to redeem the Rights or if Subsection 5.1(a) is applicable within 10
Business Days after the holders of Shares of the holders of Rights have approved
a redemption of Rights in accordance with Section 5.1(i) or (j), as the case may
be, the Company shall give notice of redemption to the holders of the then
outstanding Rights by mailing such notice to each such holder at his last
address as it appears upon the registry books of the Rights Agent or, prior to
the Separation Time, on the registry books of the transfer agent for the Voting
Shares. Any notice which is mailed in the manner herein provided shall be deemed
given, whether or not the holder receives the notice. Each such notice of
redemption will state the method by which the payment of the Redemption Price
will be made. The Company may not redeem, acquire or purchase for value any
Rights at any time in any manner other than specifically set forth in this
Section 5.1 or in connection with the purchase of Shares prior to the Separation
Time.

(i)             If
a redemption of Rights pursuant to Subsection 5.1(a) or a waiver of a Flip-in
Event pursuant to Section 5.1(b) is proposed at any time prior to the Separation
Time, such redemption or waiver shall be submitted for approval to the holders
of Voting Shares. Such approval shall be deemed to have been given if the
redemption or waiver is approved by the affirmative vote of a majority of the
votes cast by Independent Shareholders represented in person or by proxy at a
meeting of such holders duly held in accordance with applicable laws.

(j)            
If a redemption of Rights pursuant to Subsection 5.1(a) is proposed at any time
after the Separation Time, such redemption shall be submitted for approval to
the holders of Rights. Such approval shall be deemed to have been given if the
redemption is approved by holders of Rights by a majority of the votes cast by
the holders of Rights represented in person or by proxy at and entitled to vote
at a meeting of such holders. For the purposes hereof, each outstanding Right
(other than Rights which are Beneficially Owned by any Person referred to in
clauses (i) to (v) inclusive of the definition of Independent Shareholders)
shall be entitled to one vote, and the procedures for the calling, holding and
conduct of the meeting shall be those, as nearly as may be, which are provided
in the Companys by-laws and the British Columbia Business Corporations Act with
respect to meetings of shareholders of the Company.

Agreement or in respect of any Right after the Expiration Time, except the
Rights Agent as specified in Section 4.1 of this Agreement.

**5.3**                        **Issuance of New Rights Certificates**

Notwithstanding any of the provisions of this Agreement or the
Rights to the contrary, the Company may, at its option, issue new Rights
Certificates evidencing Rights in such form as may be approved by the Board of
Directors to reflect any adjustment or change in the number or kind or class of
securities purchasable upon exercise of Rights made in accordance with the
provisions of this Agreement.

**5.4**                        **Supplements
and Amendments**

(a)             The
Company may make amendments to this Agreement to correct any clerical or
typographical error or which are required to maintain the validity of this
Agreement as a result of any change in any applicable legislation or regulations
or rules thereunder. The Company may, prior to the date of the shareholders
meeting to be held prior to the Meeting Deadline Date referred to in Section
5.15(b), supplement, amend, vary, rescind or delete any of the provisions of
this Agreement and the Rights without the approval of any holders of Rights or
Voting Shares in order to make any changes which the Board of Directors acting
in good faith may deem necessary or desirable. Notwithstanding anything in this
Section 5.4 to the contrary, no such supplement or amendment shall be made to
the provisions of Article 4 except with the written concurrence of the Rights
Agent to such supplement or amendment.

(b)             Subject
to Subsection 5.4(a) and the prior approval of the Toronto Stock Exchange (if
required), the Company may, with the prior approval of the holders of Voting
Shares obtained as set forth below, at any time before the Separation Time,
supplement, amend, vary, rescind or delete any of the provisions of this
Agreement and the Rights (whether or not such action would materially adversely
affect the interests of the holders of Rights generally). Such consent shall be
deemed to have been given if the action requiring such approval is authorized by
the affirmative vote of a majority of the votes cast by Independent Shareholders
present or represented at and entitled to be voted at a meeting of the holders
of Voting Shares duly called and held in compliance with applicable laws and the
articles and by-laws of the Company.

(c)             Subject
to Subsection 5.4(a), the Company may, with the prior approval of the holders of
Rights, at any time on or after the Separation Time, supplement, amend, vary,
rescind or delete any of the provisions of this Agreement and the Rights
(whether or not such action would materially adversely affect the interests of
the holders of Rights generally), provided that no such amendment, variation or
deletion shall be made to the provisions of Article 4 except with the written
concurrence of the Rights Agent thereto.

(d)            
Any approval of the holders of Rights shall be deemed to have been given if the
action requiring such approval is authorized by the affirmative votes of the
holders of Rights present or represented at and
entitled to be voted at a meeting of the holders of Rights and representing a
majority of the votes cast in respect thereof. For the purposes hereof, each
outstanding Right (other than Rights which are void pursuant to the provisions
hereof) shall be entitled to one vote, and the procedures for the calling,
holding and conduct of the meeting shall be those, as nearly as may be, which
are provided in the Companys by-laws with respect to meetings of shareholders
of the Company.

37

---

(e)             Any
amendments made by the Company to this Agreement pursuant to Subsection 5.4(a)
which are required to maintain the validity of this Agreement as a result of any
change in any applicable legislation or regulations or rules thereunder shall:

(i)            
 if made before the Separation Time, be submitted to the shareholders of
the Company at the next meeting of shareholders and the shareholders may, by the
majority referred to in Subsection 5.4(b), confirm or reject such amendment;

(ii)            
if made after the Separation Time, be submitted to the holders of Rights at a
meeting to be called for on a date not later than immediately following the next
meeting of shareholders of the Company and the holders of Rights may, by
resolution passed by the majority referred to in Subsection 5.4(d), confirm or
reject such amendment.

Any such amendment shall be effective
from the date of the resolution of the Board of Directors adopting such
amendment, until it is confirmed or rejected or until it ceases to be effective
(as described in the next sentence) and, where such amendment is confirmed, it
continues in effect in the form so confirmed. If such amendment is rejected by
the shareholders or the holders of Rights or is not submitted to the
shareholders or holders of Rights as required, then such amendment shall cease
to be effective from and after the termination of the meeting (or any
adjournment of such meeting) at which it was rejected or to which it should have
been but was not submitted or from and after the date of the meeting of holders
of Rights that should have been but was not held, and no subsequent resolution
of the Board of Directors to amend this Agreement to substantially the same
effect shall be effective until confirmed by the shareholders or holders of
Rights as the case may be.

**5.5**                        **Fractional Rights and Fractional Shares**

(a)            
The Company shall not be required to issue fractions of Rights or to distribute
Rights Certificates which evidence fractional Rights. After the Separation Time,
in lieu of issuing fractional Rights, the Company shall pay to the holders of
record of the Rights Certificates (provided the Rights represented by such
Rights Certificates are not void pursuant to the provisions of Subsection
3.1(b), at the time such fractional Rights would otherwise be issuable), an
amount in cash equal to the fraction of the Market Price of one whole Right that
the fraction of a Right that would otherwise be issuable is of one whole Right.

38

---

(b)            
The Company shall not be required to issue fractions of Shares upon exercise of
Rights or to distribute certificates which evidence fractional Shares. In lieu
of issuing fractional Shares, the Company shall pay to the registered holders of
Rights Certificates, at the time such Rights are exercised as herein provided,
an amount in cash equal to the fraction of the Market Price of one Share that
the fraction of a Share that would otherwise be issuable upon the exercise of
such Right is of one whole Share at the date of such exercise.

**5.6**                        **Rights
of Action**

Subject to the terms of this Agreement, all rights of action in
respect of this Agreement, other than rights of action vested solely in the
Rights Agent, are vested in the respective holders of the Rights. Any holder of
Rights, without the consent of the Rights Agent or of the holder of any other
Rights, may, on such holders own behalf and for such holders own benefit and
the benefit of other holders of Rights enforce, and may institute and maintain
any suit, action or proceeding against the Company to enforce such holders
right to exercise such holders Rights, or Rights to which such holder is
entitled, in the manner provided in such holders Rights Certificate and in this
Agreement. Without limiting the foregoing or any remedies available to the
holders of Rights, it is specifically acknowledged that the holders of Rights
would not have an adequate remedy at law for any breach of this Agreement and
will be entitled to specific performance of the obligations under, and
injunctive relief against actual or threatened violations of the obligations of
any Person subject to, this Agreement.

**5.7**                        **Regulatory Approvals**

Any obligation of the Company or action or event contemplated
by this Agreement shall be subject to the receipt of any requisite approval or
consent from any governmental or regulatory authority, including without
limiting the generality of the foregoing, any necessary approvals of The Toronto
Stock Exchange, or any other applicable stock exchange or market.

**5.8**                        **Notice
of Proposed Actions**

In case the Company shall propose after the Separation Time and
prior to the Expiration Time to effect the liquidation, dissolution or winding
up of the Company or the sale of all or substantially all of the Companys
assets, then, in each such case, the Company shall give to each holder of a
Right, in accordance with Section 5.9 hereof, a notice of such proposed action,
which shall specify the date on which such Flip-in Event, liquidation,
dissolution, or winding up is to take place, and such notice shall be so given
at least 20 Business Days prior to the date of taking of such proposed action by
the Company.

With Money Laundering Legislation**

The Rights Agent shall retain the right not to act and shall
not be liable for refusing to act if, due to a lack of information or for any
other reason whatsoever, the Rights Agent reasonably determines that such an act

or anti-terrorist legislation, regulation or guideline. Further, should the
Rights Agent reasonably determine at any time that its acting under this
Agreement has resulted in it being in non-compliance with any applicable
anti-money laundering or anti-terrorist legislation, regulation or guideline,
then it shall have the right to resign on 10 days written notice to the
Company, provided: (i) that the Rights Agents written notice shall describe the

or causing to be transferred personal information to the Rights Agent, obtain
and retain required consents of the relevant individuals to the collection, use
and disclosure of their personal information, or will have determined that such
consents either have previously been given upon which the parties can rely or
are not required under applicable Privacy Laws.

**5.19**                      **Declaration
as to Non-Canadian Holders**

If in the opinion of the Board of Directors (who may rely upon
the advice of counsel) any action or event contemplated by this Agreement would
require compliance by the Company with the securities laws or comparable
legislation of a jurisdiction outside Canada or the United States, the Board of
Directors acting in good faith shall take such actions as it may deem
appropriate to ensure such compliance. In no event shall the Company or the
Rights Agent be required to issue or deliver Rights or securities issuable on
exercise of Rights to persons who are citizens, residents or nationals of any
jurisdiction other than Canada or the United States, in which such issue or
delivery would be unlawful without registration of the relevant Persons or
securities for such purposes.

in Counterparts**

This Agreement may be executed in any number of counterparts
and each of such counterparts shall for all purposes be deemed to be an

NORTHERN DYNASTY MINERALS LTD.

SHAREHOLDER RIGHTS AGREEMENT (as defined below)

[Form of Rights Certificate]

|Certificate No. | Rights
|--------------- | ------

THE RIGHTS ARE SUBJECT TO REDEMPTION, AT THE OPTION OF THE
TRUST, AND AMENDMENT OR TERMINATION ON THE TERMS SET FORTH IN THE SHAREHOLDER
RIGHTS AGREEMENT (AS DEFINED BELOW). UNDER CERTAIN CIRCUMSTANCES (SPECIFIED IN
SUBSECTION 3.1(b) OF THE SHAREHOLDER RIGHTS AGREEMENT (AS DEFINED BELOW)),
RIGHTS BENEFICIALLY OWNED BY AN ACQUIRING PERSON OR CERTAIN RELATED PARTIES, OR

Rights Certificate

This certifies that , or registered assigns, is the registered
holder of the number of Rights set forth above, each of which entitles the
registered holder thereof, subject to the terms, provisions and conditions of
the Shareholder Rights Plan Agreement, dated as of May 17, 2013 as the same may
be amended or supplemented from time to time (the Shareholder Rights
Agreement), between Northern Dynasty Minerals Ltd., a Company incorporated
under the British Columbia Business Corporations Act, (the Company) and
Computershare Investor Services Inc., a trust company incorporated under the
laws of Canada (the Rights Agent) (which term shall include any
successor Rights Agent under the Shareholder Rights Agreement), to purchase from
the Company at any time after the Separation Time (as such term is defined in
the Shareholder Rights Agreement) and prior to the Expiration Time (as such term
is defined in the Shareholder Rights Agreement), one fully paid common share of
the Company (a Share) at the Exercise Price referred to below, upon
presentation and surrender of this Rights Certificate with the Form of Election
to Exercise (in the form provided hereinafter) duly executed and submitted to
the Rights Agent at its principal office in any of the cities of Vancouver and
Toronto. Until adjustment thereof in certain events as provided in the
Shareholder Rights Agreement, the Exercise Price shall be:

(a)            
until the Separation Time, an amount equal to three times the Market Price (as
such term is defined in the Shareholder Rights Agreement), from time to time,
per Share; and

(b)            
from and after the Separation Time, an amount equal to three times the Market
Price, as at the Separation Time, per Share.

In certain circumstances described in the Shareholder Rights
Agreement, each Right evidenced hereby may entitle the registered holder thereof
to purchase or receive assets, debt securities or shares of the Company other than Shares, or more or less than
one Share, all as provided in the Shareholder Rights Agreement.

This Rights Certificate is subject to all of the terms and
provisions of the Shareholder Rights Agreement, which terms and provisions are
incorporated herein by reference and made a part hereof and to which Shareholder
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Rights Agent, the Company and the holders of the Rights Certificates. Copies of
the Shareholder Rights Agreement are on file at the registered office of the
Company and are available upon request.

This Rights Certificate, with or without other Rights
Certificates, upon surrender at any of the offices of the Rights Agent
designated for such purpose, may be exchanged for another Rights Certificate or
Rights Certificates of like tenor and date evidencing an aggregate number of
Rights equal to the aggregate number of Rights evidenced by the Rights
Certificate or Rights Certificates surrendered. If this Rights Certificate shall
be exercised in part, the registered holder shall be entitled to receive, upon
surrender hereof, another Rights Certificate or Rights Certificates for the
number of whole Rights not exercised.

Subject to the provisions of the Shareholder Rights Agreement,
the Rights evidenced by this Rights Certificate may be, and under certain
circumstances are required to be, redeemed by the Company at a redemption price
of $0.00001 per Right.

No fractional Shares will be issued upon the exercise of any
Right or Rights evidenced hereby, but in lieu thereof a cash payment will be
made, as provided in the Shareholder Rights Agreement.

No holder of this Rights Certificate, as such, shall be
entitled to vote or receive dividends or be deemed for any purpose the holder of
Shares or of any other securities which may at any time be issuable upon the
exercise hereof, nor shall anything contained in the Shareholder Rights
Agreement or herein be construed to confer upon the holder hereof, as such, any
of the Rights of a shareholder of the Company or any right to vote for the
election of directors or upon any matter submitted to shareholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting shareholders (except as
provided in the Shareholder Rights Agreement), or to receive dividends or
subscription rights, or otherwise, until the Rights evidenced by this Rights
Certificate shall have been exercised as provided in the Shareholder Rights
Agreement.
