from the zone 2, panel 5 mining area. We have developed and are optimizing techniques to deal with
abandoned freezepipes from the freezewall for zone 2, panels 1, 2, and 3. These techniques have
been successful so far, and the related risk to 2010 production noted in our annual MD&#038;A is no
longer expected to be an issue.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco is well positioned as the world becomes increasingly focused on nuclear as a source of
clean, reliable and affordable energy. We are among the world&#146;s largest players in a market where
demand is growing.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our vision is to be a dominant nuclear energy company producing uranium fuel and generating clean
electricity. We are already one of the largest uranium producers in the world, and when we sold our
gold segment late last year, became a pure-play nuclear energy investment.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our strategy is to double annual uranium production to 40&nbsp;million pounds by 2018, which we plan to
accomplish with our existing operating and development properties, and other projects already in
our portfolio. Our fuel services segment is helping to support this growth by broadening our
business relationships and expanding our uranium market share. And our investment in the Bruce
Power Limited Partnership is an excellent source of earnings and cash flow.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">You can read more about our strategy in our 2009 annual MD&#038;A.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We are in the fortunate position of having the financial strength to advance our growth plans. In
our 2009 annual MD&#038;A we talked about our plans to increase expenditures, both capitalized and
expensed, to achieve our growth strategy. We are steadfastly focused on the long-term, spending
prudently today for greater benefit tomorrow.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>A great start to the year</B>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Net earnings this quarter were 73% higher than they were in the same quarter of 2009. This was
mainly due to $31&nbsp;million in after-tax profit we recorded this quarter for unrealized
mark-to-market gains on financial instruments. Adjusted net earnings were 8% higher.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Revenues were 2% lower than in the first quarter of 2009 due to lower sales volumes and slightly
lower Canadian dollar realized prices in our uranium segment. Our realized prices were impacted by
a stronger Canadian dollar ($US realized prices increased 15%). Higher sales volumes in fuel
services, and higher realized prices in electricity, partially offset the impact of the uranium
segment.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Uranium market update</B>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">There are several things of note this quarter.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The US and Russia announced the signing of a new nuclear arms control treaty. If the treaty is
ratified by lawmakers in both countries, it will mandate a reduction in their arsenals. While it is
expected this will result in weapons being taken out of active service, there has been no
commitment to dismantle nuclear weapons and no discussion of commercializing the contained uranium.
We do not expect the new treaty will have any impact on the uranium market.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The US also hosted a Nuclear Security Summit in mid April, where many countries announced that they
were taking action to secure nuclear materials around the globe. Many of these announcements are
not new to the nuclear industry. In fact, the commitment by the US and Russia to each dispose of 34
tonnes of surplus weapons grade plutonium has been under discussion for many years and we have
included this supply source in our forecast of secondary supplies since the late 1990&#146;s. Both the
US and Russia have been importing fresh and spent highly enriched uranium from many countries for a
number of years. In the US, this is carried out by the National Nuclear Security Administration and
a portion of this product is included in the excess US Department of Energy (DOE)&nbsp;inventories.
These inventories, which are already included in supply forecasts, are not expected to enter the
market at a rate of greater than about 5&nbsp;million pounds per year.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In 2009, the DOE announced it would use its uranium inventories to pay for certain services. As
payment in 2010, it plans to transfer about 2.4&nbsp;million pounds U<SUB style="FONT-size: 85%; vertical-align: text-bottom">3</SUB>O<SUB style="FONT-size: 85%; vertical-align: text-bottom">8</SUB>
equivalent to the United States Enrichment Corporation (USEC). USEC has already sold about 0.5
million pounds U<SUB style="FONT-size: 85%; vertical-align: text-bottom">3</SUB>O<SUB style="FONT-size: 85%; vertical-align: text-bottom">8</SUB> equivalent into the spot market. Early in 2010, the DOE
asked for budget funds in future years to pay for these services directly, noting its statutory
obligation not to adversely impact the uranium market. It is possible however, that Congress will
elect not to provide the funds as requested.

estimated earlier this year. However this level could be significantly higher if demand arises from

adjusted by inflation indices, and market referenced prices (spot and long-term indicators).

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We use adjusted net earnings, a non-GAAP measure, as a more meaningful way to compare our financial
performance from period to period. Adjusted net earnings is our GAAP-based net earnings adjusted
for one-time costs, writedowns, gains and unrealized mark-to-market losses on our financial
instruments, which we believe do not reflect underlying performance.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Adjusted net earnings is non-standard supplemental information, and not a substitute for financial
information prepared according to GAAP. Other companies may calculate this measure differently. The
table below reconciles adjusted net earnings with our net earnings.

prices that are lower than current market prices. These older contracts are beginning to expire,

agreement with the OPA and financial contract revenue. BPLP recognized revenue of $103&nbsp;million this
quarter under its agreement with the OPA. The equivalent of about 22% of BPLP&#146;s output was sold
under financial contracts this quarter, compared to 64% in the first quarter of 2009.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">During the quarter, we continued to evaluate key accounting policy alternatives and implementation
decisions, but have not yet completed our analysis of the full accounting effects of adopting IFRS.
In the second quarter of 2010, we plan to finalize our analysis of accounting policy decisions and
the quantification of our January&nbsp;1, 2010 opening IFRS balances. Communication of the results of
that analysis will follow.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Senior management and the audit committee have approved our IFRS accounting policies, but IFRS
standards are evolving and may be different at the time of transition. The International Accounting
Standards Board (IASB)&nbsp;has several projects underway that could affect the differences between
Canadian GAAP and IFRS. For example, we expect that the standards for consolidation, liabilities,
discontinued operations, financial instruments, employee benefits and joint ventures could change
before we adopt IFRS, and that IFRS for income taxes may change at a later date. We have been
monitoring and evaluating these changes, and our analysis incorporates the standards we expect to
be in effect at the time of transition.

Taxes</I>, requires companies to credit (or charge) income tax directly to equity whether or not the
related item is credited (or charged) directly to equity in the same period. That means we may have
to recognize some income tax effects directly in equity rather than through net income or loss.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Under Canadian GAAP, we cannot recognize deferred tax for a temporary difference that arises from

generally accepted accounting principles (GAAP)&nbsp;and follow the same accounting principles

annual financial statements, they should be read in conjunction with Cameco&#146;s annual
consolidated financial statements included in the 2009 annual financial review. Certain
comparative figures for the prior period have been reclassified to conform to the current

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">At March&nbsp;31, 2010, current taxes payable in the amount of $11,970,000 (December&nbsp;31, 2009 -
$31,140,000), have been included in accounts payable and accrued liabilities.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">In 2008, as part of the ongoing annual audits of Cameco&#146;s Canadian tax returns, Canada
Revenue Agency (CRA)&nbsp;disputed the transfer pricing methodology used by Cameco and its wholly
owned Swiss subsidiary, Cameco Europe Ltd. (CEL), in respect of sale and purchase agreements
for uranium products. In December&nbsp;2008, CRA issued a notice of reassessment, which
increased Cameco&#146;s 2003 Canadian taxable income by approximately $43,000,000 (this
reassessment was superseded by a reassessment issued in February&nbsp;2009 and neither reassessment resulted in more than a nominal amount of cash taxes becoming payable for that
year). In December&nbsp;2009, CRA issued a notice of reassessment for the 2004 tax return, which
increased Cameco&#146;s 2004 Canadian taxable income by approximately $108,000,000 (which, again,
did not result in more than a nominal amount of cash taxes becoming payable for that year).
Cameco believes it is likely that CRA will reassess Cameco&#146;s tax returns for the years 2005
through 2009 on a similar basis.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">Late in 2009, CRA&#146;s Transfer Pricing Review Committee decided not to impose a penalty for
2004 based on the documentation that had been submitted by Cameco. This followed the same
decision by the Transfer Pricing Review Committee late in 2008 for the 2003 notice of
reassessment.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">Having regard to advice from its external advisors, Cameco&#146;s opinion is that CRA&#146;s position
is incorrect, and Cameco is contesting CRA&#146;s position. However, to reflect the
uncertainties of CRA&#146;s appeals process and litigation, Cameco decided to increase its
reserve for uncertain tax positions and recognize an income tax expense of $9,000,000 in
2009, bringing the cumulative tax provision related to this matter for the years 2003
through 2009 to $24,000,000. No provisions for penalties or interest have been recorded.
We do not expect any cash taxes to be payable due to availability of elective deductions and
tax loss carryforwards. While the resolution of this matter may result in liabilities that
are higher or lower than the reserve, management believes that the ultimate resolution will
not be material to Cameco&#146;s financial position, results of operations or liquidity over the
period. However, an unfavourable outcome for the years 2003 to 2009 could be material to
Cameco&#146;s financial position, results of operations or cash flows in the year(s) of
resolution.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">Further to Cameco&#146;s decision to contest CRA&#146;s 2003 reassessment, a Notice of Appeal was
filed with the Tax Court of Canada on July&nbsp;22, 2009 and the litigation process is
proceeding. Cameco expects to file a Notice of Appeal for the 2004 reassessment in 2010.

    <TD>On February&nbsp;12, 2004, Cameco, Cameco Bruce Holdings II Inc., BPC Generation
Infrastructure Trust and TransCanada Pipelines Limited (collectively, the
&#147;Consortium&#148;) sent a notice of claim to British Energy Limited and British Energy
International Holdings Limited (collectively, BE) requesting, amongst other things,
indemnification for breach of a representation and warranty contained in the February
14, 2003, Amended and Restated Master Purchase Agreement. The alleged breach is that
the Unit 8 steam generators were not &#147;in good condition, repair and proper working
order, having regard to their use and age.&#148; This defect was discovered during a
planned outage conducted just after closing. As a result of this defect, the planned
outage had to be significantly extended. The Consortium has claimed damages in the
amount of $64,558,200 being 79.8% of the $80,900,000 of damages actually incurred,
plus an unspecified amount to take into account the reduced operating life of the
steam generators. By agreement of the parties, an arbitrator has been appointed to
arbitrate the claims and a schedule has been set for the next steps in the proceeding.</TD>

    <TD>The Unit 8 steam generators require on-going monitoring and maintenance as a result of
the defect. In addition to the $64,558,200 in damages sought in the notice of claim, the
claim seeks an additional $4,900,000 spent on inspection, monitoring and maintenance of
Unit 8, and $31,900,000 in costs for future monitoring and maintenance, as well as
repair costs and lost revenue due to anticipated unplanned outages as a consequence of
the defect in Unit 8. The initial claim had also sought damages for the early
replacement of the Unit 8 steam generators due to the defect shortening their useful
operating lives. However, recent inspection data and analysis of the condition of the
Unit 8 steam generators now indicates that they will continue to function until the end
of the Consortium&#146;s lease of the Bruce Power facility in 2018, as was expected at the
time the MPA was entered into. The claim for early replacement was thus abandoned via an
amendment to the claim on August&nbsp;7, 2009. The parties have completed the discovery
process and the arbitration hearing is currently underway.</TD>

    <TD>Under a supply contract with the Ontario Power Authority (OPA), BPLP is
entitled to receive payments from the OPA during periods when the market price for
electricity in Ontario is lower than the floor price defined under the agreement
during a calendar year. On July&nbsp;6, 2009, BPLP and the OPA amended the supply contract
such that beginning in 2009, the annual payments received will not be subject to
repayment in future
years. Previously, the payments received under the agreement were subject to repayment
during the entire term of the contract, dependent on the spot price in future periods.
The agreement remains in effect until the earlier of December&nbsp;31, 2019 or one year after
the shutdown of the BPLP units. During 2010, BPLP recorded $103,000,000 under this
agreement which was recognized as revenue with Cameco&#146;s share being $33,000,000.</TD>
