<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 15pt; text-align: justify; text-indent: 0.5in; background-color: white">On
February 15, 2018, Actinium Pharmaceuticals, Inc. (the &ldquo;Company&rdquo;) announced that it is commencing a rights offering
to its stockholders and certain participating warrant holders (&ldquo;Rights Offering&rdquo;). Pursuant to the Rights Offering,
the Company has distributed, at no charge to holders of record of the Company&rsquo;s common stock and certain participating warrants
as of February 14, 2018 (the &ldquo;Record Date&rdquo;), non-transferable subscription rights to purchase up to an aggregate of
35,714,285 units at a subscription price per unit of $0.70, all as set forth in a prospectus supplement filed on February 15, 2018
with the Securities and Exchange Commission (the &ldquo;Prospectus Supplement&rdquo;). As set forth in the Prospectus Supplement,
the subscription rights will be exercisable for up to an aggregate of $25.0 million of units, subject to increase at the discretion
of the Company, with aggregate participation to be allocated among holders on a pro rata basis if in excess of that threshold.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">Each unit will consist
of one share of common stock, 0.25 series A warrants (&ldquo;Series A Warrant&rdquo;) and 0.75 series B warrants (&ldquo;Series
B Warrant&rdquo;). Each whole Series A Warrant and each whole Series B Warrant will be exercisable for one share of common stock.
The Series A Warrants will have a term of 12 months from the date of issuance and will be exercisable at a price of $0.90. The
Series B Warrants will have a term of 30 months from the date of issuance and will have an exercise price of $1.10. <FONT STYLE="font-family: Times New Roman, Times, Serif">The

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">Holders who fully exercise
their basic subscription rights will be entitled, if available, to subscribe for an additional amount of units that are not purchased
by other holders, on a pro rata basis and subject to the $25.0 million aggregate offering threshold and other ownership limitations.
The subscription rights are non-transferrable and may only be exercised during the anticipated subscription period of Thursday,
February 15, 2018 through 5:00 PM ET on Friday, March 2, 2018, unless extended as set forth in the Prospectus Supplement. In connection
with the Rights Offering, the Company entered into a Dealer-Manager Agreement (the &ldquo;Agreement&rdquo;) with Maxim Group LLC

the Company engaged Maxim as the exclusive dealer-manager in connection with the Rights Offering. Under the terms and subject to
the conditions contained in the Agreement, Maxim will provide marketing assistance and advice in connection with Rights Offering,
respond to requests for information and materials relating to the Rights Offering in coordination with the information agent and,
in accordance with customary practice, solicit the exercise of the subscription rights and subscriptions for the Rights Offering
and enter into selected dealer agreements with other registered broker-dealers in connection with the Rights Offering.&nbsp; As

of 1933, as amended. Maxim will not underwrite and is not otherwise obligated to purchase any of the securities to be issued in
the Rights Offering and does not make any recommendation with respect to such securities.</P>

any lawsuit, claim or proceeding is brought against any indemnified party in respect of which indemnification may be sought against
the indemnifying party pursuant to this Section 11, such indemnified party shall promptly notify the indemnifying party of the
commencement of such lawsuit, claim or proceeding; provided, however, that the failure so to notify the indemnifying party shall
not relieve the indemnifying party from any obligation or liability which it may have under this Section 11 except to the extent
that it has been prejudiced in any material respect by such failure and in any event shall not relieve the indemnifying party
from any other obligation or liability which it may have to such indemnified party otherwise than under this Section 11. In case
any such lawsuit, claim or proceeding shall be brought against any indemnified party and such indemnified party shall notify the
indemnifying party of the commencement of such lawsuit, claim or proceeding, the indemnifying party shall be entitled to participate
in such lawsuit, claim or proceeding, and, after written notice from the indemnifying party to such indemnified party, to assume
the defense of such lawsuit, claim or proceeding with counsel of its choice at its expense; provided, however, that such counsel
shall be satisfactory to the indemnified party in the exercise of its reasonable judgment. Notwithstanding the election of the
indemnifying party to assume the defense of such lawsuit, claim or proceeding, such indemnified party shall have the right to
employ separate counsel and to participate in the defense of such lawsuit, claim or proceeding, and the indemnifying party shall
bear the reasonable fees, costs and expenses of such separate counsel (and shall pay such reasonable fees, costs and expenses
promptly after receipt of any invoice therefor) if: (i) the use of counsel chosen by the indemnifying party to represent such
indemnified party would present such counsel with a conflict of interest; (ii) the defendants in, or targets of, any such lawsuit,
claim or proceeding include both an indemnified party and the indemnifying party, and such indemnified party shall have reasonably
concluded that there may be legal defenses available to it or to other indemnified parties which are different from or in addition
to those available to the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense
of such action on behalf of the indemnified party); (iii) the indemnifying party shall not have employed counsel satisfactory
to such indemnified party, in the exercise of such indemnified party&rsquo;s reasonable judgment, to represent such indemnified
party within a reasonable time after notice of the institution of any such lawsuit, claim or proceeding; or (iv) the indemnifying
party shall authorize such indemnified party to employ separate counsel at the expense of the indemnifying party. The foregoing
indemnification commitments shall apply whether or not the indemnified party is a formal party to any such lawsuit, claim or proceeding.
The indemnifying party shall not be liable for any settlement of any lawsuit, claim or proceeding effected without its consent
(which consent will not be unreasonably withheld), but if settled with such consent, the indemnifying party agrees, subject to
the provisions of this Section 11, to indemnify the indemnified party from and against any loss, damage or liability by reason
of such settlement. The Company agrees to notify Maxim promptly, or cause Maxim to be notified promptly, of the assertion of any
lawsuit, claim or proceeding against the Company, any of its officers or directors or any Person who controls any of the foregoing
within the meaning of Section 20(a) of the Exchange Act, arising out of or relating the Rights Offering. The Company further agrees
that any settlement of a lawsuit, claim or proceeding against it arising out of Rights Offering shall include an explicit and
unconditional release from the parties bringing such lawsuit, claim or proceeding of Maxim, its respective affiliates, and any
officer, director, employee or agent of Maxim, and any Person controlling (within the meaning of Section 20(a) of the Exchange
Act) Maxim.</FONT></P>

order to provide for contribution in circumstances in which the indemnification provided for in this Section 11 for any reason
held to be unavailable from any indemnifying party or is insufficient to hold harmless a party indemnified thereunder, the Company,
on the one hand, and Maxim, on the other hand, shall contribute to the aggregate losses, claims, damages, liabilities and expenses
of the nature contemplated by such indemnification provision (including any investigation, legal and other expenses incurred in
connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting
in the case of losses, claims, damages, liabilities and expenses suffered by the Company, any contribution received by the Company
from Persons, other than Maxim, who may also be liable for contribution, including Persons who control the Company within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, officers of the Company who signed the Registration
Statement and directors of the Company) as incurred to which the Company and Maxim may be subject, in such proportions as is appropriate
to reflect the relative benefits received by the Company, on the one hand, and Maxim, on the other hand, from the Rights Offering
or, if such allocation is not permitted by applicable law, in such proportions as are appropriate to reflect not only the relative
benefits referred to above but also the relative fault of the Company, on the one hand, and Maxim, on the other hand, in connection
with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other
relevant equitable considerations. The relative benefits received by the Company, on the one hand, and Maxim, on the other hand,
shall be deemed to be in the same proportion as: (x) the total proceeds from the Rights Offering (net of the fees of the Dealer-Manager
set forth in Section 6 hereof, but before deducting expenses) received by the Company bears to (y) the fees of the Dealer-Manager
set forth in Section 6 hereof actually received by the Dealer-Manager. The relative fault of each of the Company, on the one hand,
and Maxim, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company
or Maxim (which consists solely and exclusively of the Dealer-Manager Information) and the parties&rsquo; relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or omission. The Company and the Dealer-Manager agree
that it would not be just and equitable if contribution pursuant to this Section 11(f) were determined by pro rata allocation
or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section.
The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above
in this Section 11 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating,
preparing or defending against any litigation, or any investigation or proceeding by any judicial, regulatory or other legal or
governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement
or omission or alleged omission. Notwithstanding the provisions of this Section 11: (i) the Dealer-Manager shall not be required
to contribute any amount in excess of the fees actually received by the Dealer-Manager from the Company in connection with the
Rights Offering and (ii) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities
Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section 11, each Person controlling a Dealer-Manager within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act shall have the same rights to contribution as such Dealer-Manager, and each Person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each officer of the Company
who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as
the Company, subject in each case to clauses (i) and (ii) of the immediately preceding sentence. Any party entitled to contribution
will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which
a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may
be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may
be sought from any obligation it or they may have under this Section 11(f) or otherwise.</FONT></P>

number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver
to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise
and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000
to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such
purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the
Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the
Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder&rsquo;s right
to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific
performance and/or injunctive relief with respect to the Company&rsquo;s failure to timely deliver shares of Common Stock upon
exercise of the Warrant as required pursuant to the terms hereof.</P>

exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance
after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder&rsquo;s Affiliates, and
any other Persons acting as a group together with the Holder or any of the Holder&rsquo;s Affiliates (such Persons, &ldquo;<U>Attribution
Parties</U>&rdquo;)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below).&nbsp; For purposes
of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its Affiliates and Attribution
Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination
is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining,
nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii)
exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation,
any other Common Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein
beneficially owned by the Holder or any of its Affiliates or Attribution Parties.&nbsp; Except as set forth in the preceding sentence,
for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act
and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing
to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible
for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 2(e)
applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together
with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion
of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder&rsquo;s determination of whether this
Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties)
and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company
shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group
status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder. For purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder
may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company&rsquo;s most recent periodic or annual
report filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent
written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding.&nbsp; Upon
the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder
the number of shares of Common Stock then outstanding.&nbsp; In any case, the number of outstanding shares of Common Stock shall
be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder
or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported.
The &ldquo;<U>Beneficial Ownership Limitation</U>&rdquo; shall be 4.99% (or, upon election by a Holder prior to the issuance of
any Warrants, 9.99%) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of
shares of Common Stock issuable upon exercise of this Warrant. The Holder, upon notice to the Company, may increase or decrease
the Beneficial Ownership Limitation provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event
exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares
of Common Stock upon exercise of this Warrant held by the Holder and the provisions of this Section 2(e) shall continue to apply.
Any increase in the Beneficial Ownership Limitation will not be effective until the 61<SUP>st</SUP> day after such notice is delivered
to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity
with the terms of this Section 2(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with
the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly
give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.&nbsp;</P>

number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver

Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination
is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining,
nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii)

for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act

to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible

with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion
of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder&rsquo;s determination of whether this
Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties)
and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company
shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group
status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder. For purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder
may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company&rsquo;s most recent periodic or annual
report filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent
written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding.&nbsp; Upon
the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder
the number of shares of Common Stock then outstanding.&nbsp; In any case, the number of outstanding shares of Common Stock shall
be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder
or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported.
The &ldquo;<U>Beneficial Ownership Limitation</U>&rdquo; shall be 4.99% (or, upon election by a Holder prior to the issuance of
any Warrants, 9.99%) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of
shares of Common Stock issuable upon exercise of this Warrant. The Holder, upon notice to the Company, may increase or decrease
the Beneficial Ownership Limitation provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event
exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares
of Common Stock upon exercise of this Warrant held by the Holder and the provisions of this Section 2(e) shall continue to apply.
Any increase in the Beneficial Ownership Limitation will not be effective until the 61<SUP>st</SUP> day after such notice is delivered
to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity
with the terms of this Section 2(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with
the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly
give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.&nbsp;</P>

to the holders of record of its common stock, $0.001 par value (the &ldquo;Common Stock&rsquo;) and certain participating warrants,
as described in Actinium&rsquo;s prospectus supplement dated February 15, 2018 (as it may be amended from time to time, the &ldquo;Prospectus
Supplement&rdquo;). Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Prospectus Supplement.
Each holder of record of Common Stock or participating warrants at the close of business on February 14, 2018 (the &ldquo;Record
Date&rdquo;) will receive, at no charge, a non-transferable subscription right (the &ldquo;Subscription Right&rdquo;) for every

are being distributed in connection with the Rights Offering. Each Unit is comprised of one share of Common Stock, 0.25 Series
A Warrants, and 0.75 Series B Warrants.&nbsp;Each whole Series A Warrant and each whole Series B Warrant will be exercisable for
one share of Common Stock. Each whole Subscription Right is exercisable, upon payment of $0.70 in cash (the &ldquo;Subscription
Price&rdquo;), to purchase one Unit (the &ldquo;Basic Subscription Right&rdquo;). In addition, each Subscription Right also carries
the right to subscribe at the Subscription Price for additional Units that are not purchased by other holders pursuant to their
Basic Subscription Right (to the extent available, and subject to proration and ownership limitations) (the &ldquo;Over-Subscription
Privilege&rdquo;). A holder is entitled to exercise an Over-Subscription Privilege only if the holder fully exercises the Basic
Subscription Right. See &ldquo;The Rights Offering&rdquo; in the Prospectus Supplement.</P>

5:00 p.m., Eastern Time, on March 2, 2018, unless extended (&ldquo;the &ldquo;Expiration Date&rdquo;). If you do not exercise your
Subscription Rights before that time, your Subscription Rights will expire and will no longer be exercisable. Actinium will not
be required to issue shares to you if the Subscription Agent receives your Subscription Rights Certificate or your subscription
payment after that time. Actinium has the option to extend the Rights Offering in its sole discretion, although it does not presently
intend to do so. Actinium may extend the Rights Offering by giving oral or written notice to the Subscription Agent before the
Expiration Date. If Actinium elects to extend the Rights Offering, Actinium will issue a press release announcing the extension
no later than 9:00 a.m., Eastern Time, on the next business day after the most recently announced Expiration Date of the Rights
Offering.</P>

you are entitled is printed on the face of your Subscription Rights Certificate. You should indicate your wishes with regard to
the exercise of your Subscription Rights by completing the appropriate section on the back of your Subscription Rights Certificate
and returning the Subscription Rights Certificate with your payment to the Subscription Agent in the envelope provided.</P>

per share. The Warrants are exercisable for cash, or solely during any period when a registration statement for the exercise of
the Warrants is not in effect, on a cashless basis. The Series A Warrants and Series B Warrants may be redeemed for $0.001 per
Warrant if Actinium&rsquo;s Common Stock closes above $1.80 and $3.30 per share, respectively, for 10 consecutive trading days.

with certification as to the aggregate number of Subscription Rights exercised pursuant to the Subscription Right by each beneficial
owner of Subscription Rights on whose behalf such nominee is acting, and payment of the Subscription Price for each Unit subscribed
for. Banks, brokers and other nominee holders of Subscription Rights who exercise the Basic Subscription Right and the Over-Subscription
Privilege on behalf of beneficial owners of Subscription Rights will be required to certify to the Subscription Agent and Actinium
as to the aggregate number of Subscription Rights that have been exercised, and the number of Units that are being subscribed for
pursuant to the Over-Subscription Privilege, by each beneficial owner of Subscription Rights (including such nominee itself) on
whose behalf such nominee holder is acting. In the event such certification is not delivered in respect of a Subscription Rights
Certificate, the Subscription Agent shall for all purposes (including for purposes of any allocation in connection with the Over-Subscription
Privilege) be entitled to assume that such certificate is exercised on behalf of a single beneficial owner.</P>

rights (the &ldquo;Subscription Rights&rdquo;) to subscribe for and purchase units (&ldquo;Units&rdquo;). Each Unit entitles the
holder to one share of the Company's Common Stock, 0.25 Series A Warrants, and 0.75 Series B Warrants.&nbsp;Each whole Series A
Warrant and whole Series B Warrant will be exercisable for one share of Common Stock. The Subscription Rights and Units are described

Units but will only accept subscriptions for 35,714,285 Units, subject to increase as described in the Prospectus Supplement.&nbsp;
Accordingly, sufficient Units may not be available to honor your subscription in full.&nbsp; If exercises of Basic Subscription
Rights exceed the number of Units available in the Rights Offering, we will allocate the available Units pro-rata among the record
holders exercising the Basic Subscription Rights in proportion to the number of shares of our Common Stock held or underlying participating
warrants held on the Record Date by each of those record holders, relative to the number of shares owned on the Record Date by
all record holders exercising the Over-Subscription Privilege. If this pro-rata allocation results in any record holders receiving
a greater number of Units than the record holder subscribed for pursuant to the exercise of the Basic Subscription Rights, then
such record holder will be allocated only that number of Units for which the record holder subscribed, and the remaining Units
will be allocated among all other record holders exercising their Basic Subscription Rights on the same pro rata basis described

on 80,072,900 shares of common stock and 21,608,333 participating warrant outstanding as of February 14, 2018, we would grant
Subscription Rights to acquire 101,681,233 Units but will only accept subscriptions for 35,714,285 Units, subject to increase
as described in the Prospectus Supplement.&nbsp; Accordingly, sufficient Units may not be available to honor your subscription
in full.&nbsp; If exercises of Basic Subscription Rights exceed the number of Units available in the Rights Offering, we will
allocate the available Units pro-rata among the record holders exercising the Basic Subscription Rights in proportion to the number
of shares of our Common Stock held or underlying the participating warrants held each of those record holders, relative to the
number of shares held or underlying the participating warrants held on the Record Date by all record holders exercising the Over-Subscription
Privilege. If this pro-rata allocation results in any record holders receiving a greater number of Units than the record holder
subscribed for pursuant to the exercise of the Basic Subscription Rights, then such record holder will be allocated only that
number of Units for which the record holder subscribed, and the remaining Units will be allocated among all other record holders
exercising their Basic Subscription Rights on the same pro rata basis described above. The proration process will be repeated
until all Units have been allocated. If for any reason the amount of Units allocated to you is less than you have subscribed for,
then the excess funds held by the Subscription Agent on your behalf will be returned to you, without interest or deduction within
10 business days after the Rights Offering has expired, and all prorating calculations and reductions contemplated by the terms
of the Rights Offering have been effected, and we will have no further obligations to you.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: center"><B>NOTICE OF IMPORTANT TAX INFORMATION</B></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: center"><B>ACTINIUM PHARMACEUTICALS, INC.</B></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: center"><B>&nbsp;</B></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The tax information is provided in connection
with the prospectus of Actinium Pharmaceuticals, Inc. (&ldquo;Actinium&rdquo;) dated February 15, 2018 (the &ldquo;Prospectus
Supplement&rdquo;).</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Under the U.S. federal income tax laws,
dividend payments (including constructive dividends) that may be made by Actinium on shares of its Common Stock acquired through
the exercise of the Subscription Rights or exercise of the Series A Warrants or Series B Warrants, themselves issued through the
exercise of the Subscription Rights, may be subject to backup withholding. Generally such payments will be subject to backup withholding
unless the holder (i) is exempt from backup withholding or (ii) furnishes the payer with its correct taxpayer identification number
(&ldquo;TIN&rdquo;) and certifies, under penalties of perjury, that the number provided is correct and provides certain other certifications.
Each holder that exercises Subscription Rights and wants to avoid backup withholding must, unless an exemption applies, provide
the Subscription Agent, as Actinium's agent in respect of the exercised Subscription Rights, with such holder's correct TIN (or
with a certification that such holder is awaiting a TIN) and certain other certifications by completing the enclosed Form W-9 (Request
for Taxpayer Identification Number and Certification).</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Certain holders (including, among others,
corporations and certain foreign individuals) are exempt from these backup withholding and reporting requirements. In general,
in order for a foreign holder to qualify as an exempt recipient, that holder must, in the case of a foreign individual, submit
a properly completed Form W-8BEN, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting
(Individuals) or, in the case of a foreign corporation, Form W-8BEN-E, Certificate of Status of Beneficial Owner for United States
Tax Withholding and Reporting (Entities) or other appropriate form (instead of a Form W-9), signed under the penalties of perjury,
attesting to such holder's foreign status. Such Form W-8BEN or Form W-8BEN-E may be obtained from the Subscription Agent. Although
a foreign holder may be exempt from backup withholding, payments of dividends may be subject to withholding tax, currently at a
30% rate (or, if certain tax treaties apply, such applicable lower rate) or withholding tax at a rate of 30% under FATCA unless
an exemption from FATCA withholding is certified. Exempt U.S. holders should indicate their exempt status on Form W-9 to avoid
possible erroneous backup withholding. See the enclosed Form W-9 (Request for Taxpayer Identification Number and Certification)
for additional instructions. Holders are urged to consult their own tax advisors to determine whether they are exempt from withholding
and reporting requirements.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">If backup withholding applies, Actinium
or the Subscription Agent, as the case may be, will be required to withhold (currently at a 24% rate) on any dividend payments
made to a holder that exercises Subscription Rights. Backup withholding is not an additional tax. Rather, the amount of backup
withholding can be credited against the U.S. federal income tax liability of the holder subject to backup withholding, provided
that the required information is provided to the Internal Revenue Service (&ldquo;IRS&rdquo;). If backup withholding results in
an overpayment of taxes, a refund may be obtained.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">A holder that exercises Subscription Rights
is required to give the Subscription Agent the TIN of the record owner of the Subscription Rights. If such record owner is an individual,
the TIN is generally the taxpayer's social security number. For most other entities, the TIN is the employer identification number.
If the Subscription Rights are in more than one name or are not in the name of the actual owner, consult the enclosed Form W-9
(Request for Taxpayer Identification Number and Certification) for additional guidelines on which number to report. If the Subscription
Agent is not provided with the correct TIN in connection with such payments, the holder may be subject to a penalty imposed by
the IRS.</P>
