<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In the first quarter of 2007, our net earnings were $59&nbsp;million ($0.16 per share diluted), $53
million lower than in 2006. The decrease in net earnings was due to lower earnings in the uranium,
electricity and gold businesses, which resulted from significantly lower sales volumes in the first
quarter of 2007 compared to the previous year. In addition, we expensed $11&nbsp;million for remediation
activities at Cigar Lake in the first quarter. Due to the uneven timing of uranium and conversion
deliveries as well as scheduled outages at Bruce Power Limited Partnership (BPLP), quarterly
results are not a good indicator of Cameco&#146;s annual results.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In the first three months of 2007, we recorded a net recovery of income taxes of $16&nbsp;million due to
the distribution of our taxable income between Canada and other countries. In the first quarter of
2007, we recorded losses in Canada and earnings in other jurisdictions.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cash from operations in the first quarter of 2007 was $139&nbsp;million compared to $286&nbsp;million in the
same period of 2006. The decrease of $147&nbsp;million reflects lower revenues in the uranium,
electricity and gold businesses as well as working capital requirements related mainly to an
increase in product inventories in the first quarter of 2007.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In our uranium business, earnings before taxes declined to $44&nbsp;million from $89&nbsp;million in the
first quarter of 2006, primarily as a result of a lower reported sales volume in the quarter.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In the first quarter of 2007, revenue from our uranium business declined by $102&nbsp;million to $183
million, as a 23% increase in the realized selling price was more than offset by a 48% decline in
reported sales volumes.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Sales volumes were down due to timing of sales deliveries, which are at the discretion of our
customers. For the past several years, the deliveries have been heavily weighted in the fourth
quarter. In 2006, the timing of deliveries through the year was unusual, with heavier weighting in
the first quarter and lighter weighting in the fourth quarter.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In addition, during the first quarter, we deferred revenue on a portion of our sales volume as the
result of our standby product loans. As previously reported, Cameco has entered into standby
product loan agreements with two of our customers. As of March&nbsp;31, 2007, Cameco had not borrowed
any material under the standby loan agreements. However, regardless of whether any material is
borrowed, we defer revenue recognition from sales to the counterparties of the standby product loan
agreements, up to the limit of the loans (5.6&nbsp;million pounds). This is in accordance with Canadian
generally accepted accounting principles (GAAP). Accordingly, in the first quarter of 2007, Cameco
has deferred revenue of $35&nbsp;million and the associated costs on sales of 0.9&nbsp;million pounds of
U<SUB style="font-size: 85%; vertical-align: text-bottom">3</SUB>O<SUB style="font-size: 85%; vertical-align: text-bottom">8. </SUB>The gross profit on the deferred sales was $20&nbsp;million.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On April&nbsp;16, 2007, Cameco gave a termination notice to the counterparty for two of its three
product loan agreements. Under the two agreements, the loan facilities terminate 30&nbsp;days after the
date of notice. Therefore, Cameco will recognize a portion of the previously deferred revenues and
costs in its earnings during the second quarter of 2007. The amount of material Cameco is able to
borrow has been reduced by 3.0&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> and 0.4&nbsp;million kg
UF<SUB style="font-size: 85%; vertical-align: text-bottom">6 </SUB>as a result of this action. Cameco is now able to borrow up to 2.6&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>of which up to 1.0&nbsp;million kgU can be borrowed in the form of
UF<SUB style="font-size: 85%; vertical-align: text-bottom">6</SUB>.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco is proceeding with a five-phase plan to restore the underground workings at Cigar Lake and
complete construction. We continue to pour concrete underground in the reinforcement area and drill
dewatering holes from surface. We are on track to dewater the mine in the third quarter of 2007,
provided that regulatory approvals are received, the current pace of placing concrete is
maintained, and the concrete plug seals sufficiently. The effectiveness of the plug will not be
known until dewatering is under way. See the MD&#038;A, which follows this news release for more
information on Cigar Lake.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For fuel services, earnings before taxes were $8&nbsp;million in the first quarter of 2007, unchanged
compared to 2006.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco&#146;s pre-tax earnings from BPLP in the first quarter of 2007 amounted to $10&nbsp;million compared
to $47&nbsp;million during the same period in 2006. This decrease in 2007 was due to lower generation
and higher operating costs related to planned outages in the quarter.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For gold, revenue decreased by $11&nbsp;million to $96&nbsp;million compared to the first quarter of 2006.
The decline in revenue was due to lower production, which more than offset the benefit of a higher
realized gold price.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Outlook for Second Quarter 2007</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We expect
consolidated earnings
[the reference to &#147;earnings&#148; should have been to &#147;revenue&#148; as disclosed in a subsequent press release issued on April&nbsp;29, 2007]
for the second quarter of 2007 to be about 50% higher than in the
first quarter, reflecting higher anticipated sales volumes for uranium, conversion and electricity
as well as an increase in the realized prices for uranium. The projection includes the recognition
of $47&nbsp;million in revenue previously deferred due to the product loan arrangements.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The projections noted above assume no major changes in Cameco&#146;s business units&#146; ability to supply
product and services and no significant changes in our current estimates for price, cost and
volume.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Outlook for the Year 2007</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In 2007, Cameco expects consolidated revenue to grow by nearly 50% over 2006 due to higher revenue
from all business segments with the largest increase being in the uranium business. We now expect
uranium revenues to increase by approximately 90% due to much stronger average realized prices
under our contracts relative to 2006 and our expectation of selling almost 4&nbsp;million pounds of
uranium into new market related contracts rather than legacy contracts.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We anticipate that almost 4&nbsp;million pounds of uranium deliveries under our legacy contracts will be
deferred from 2007 and thereby make available an equivalent quantity for sale this year. At this
point, approximately half of the 4&nbsp;million pounds has been committed. Our 2007 sales deliveries are
expected to total 33&nbsp;million pounds. Our average realized price in 2007 will be positively
impacted, as current market prices are considerably higher than the legacy contract prices.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The deferred quantities will be delivered in the future over several years at legacy contract
prices, based on negotiated schedules. Of the 4&nbsp;million pounds deferred, 1.6&nbsp;million pounds have
been deferred under an agreement that is considered to be a derivative. Accordingly, the derivative
will be recorded on the balance sheet in the second quarter of 2007 at its fair value of
approximately $11&nbsp;million with an offsetting charge to earnings.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The sale of some or all of the 4&nbsp;million pounds into new market-price contracts will help mitigate
the financial impact resulting from the water inflow at Cigar Lake.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We also anticipate that revenue from the fuel services business will be about 15% higher than in
2006 due to an anticipated 3% increase in sales deliveries and a higher average realized selling
price.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">BPLP revenues in 2007 are projected to be 18% higher than in 2006, almost entirely due to higher
expected realized prices. This earnings outlook assumes the B units will achieve a targeted
capacity factor in the low 90% range.

significant supplier of conversion services and one of two Candu fuel manufacturers in Canada.
The company&#146;s competitive position is based on its controlling ownership of the world&#146;s
largest high-grade reserves and low-cost operations. Cameco&#146;s uranium products are used to generate
clean electricity in nuclear power plants around the world, including Ontario where the company is
a partner in North America&#146;s largest nuclear electricity generating facility. The company also
explores for uranium in North America and Australia, and holds a majority interest in a mid-tier
gold company. Cameco&#146;s shares trade on the Toronto and New York stock exchanges.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For the three months ended March&nbsp;31, 2007, our net earnings were $59&nbsp;million ($0.16 per share
diluted), $53&nbsp;million lower than the net earnings of $112&nbsp;million ($0.30 per share diluted)
recorded in the first quarter of 2006. The decrease was due to lower earnings in the uranium,
electricity and gold businesses caused by significantly lower first quarter sales volumes compared
to the previous year. These declines are temporary and we expect that our annual reported sales
volumes for 2007 will be similar to those of 2006. In addition, we expensed $11&nbsp;million for
remediation activities at Cigar Lake in the first quarter. For details on the uranium, fuel
services, electricity and gold businesses, see &#147;Business Segment Results&#148; later in this report.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In the first quarter of 2007, our total costs for administration, exploration, interest and other
were $52&nbsp;million, unchanged compared to the same period of 2006. Administration costs were $1
million lower due primarily to lower stock-based compensation expenses. Exploration expenditures
were $2&nbsp;million higher, at $15&nbsp;million, with uranium exploration expenditures up $2&nbsp;million to $8
million (focused in Saskatchewan, Australia and Nunavut). Gold exploration expenditures at Centerra
Gold Inc. (Cameco&#146;s 53% owned subsidiary) were unchanged at $7&nbsp;million compared to the first
quarter of 2006.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In the first three months of 2007, we recorded a net recovery of income taxes of $16&nbsp;million due to
the distribution of our taxable income between Canada and other countries. In the first quarter of
2007, we recorded losses in Canada and earnings in other jurisdictions. Since Canadian tax rates
are higher than those of the other jurisdictions, the net result was a recovery. For more
information about income taxes, refer to note 10 of the unaudited consolidated financial statements
dated March&nbsp;31, 2007.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Earnings from operations decreased to $49&nbsp;million in the first quarter of 2007, from $138&nbsp;million
in the first quarter of 2006. The aggregate gross profit margin decreased to 26% from 35% in 2006.

2006 due to lower sales volumes in the uranium and fuel services businesses, partially offset by a
higher realized price for uranium. Revenue is driven by timing of deliveries in our uranium and
fuel services businesses, and has tended to be higher in the fourth quarter each year. However, in
2006, the deliveries were more heavily weighted in the first quarter of the year.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Net earnings do not trend directly with revenue because past results are significantly influenced
by results from Bruce Power Limited Partnership (BPLP). Prior to November&nbsp;1, 2005, the equity
method of accounting was applied to the investment in BPLP and thus no BPLP revenue or costs were
recorded. On November&nbsp;1, 2005, Cameco moved to proportionate consolidation of BPLP&#146;s financial
results. Since then, we have included our share of revenue, expenses and cash flow from the Bruce B
reactors. The adjustment in our accounting method for BPLP does not change the reporting of our net
earnings.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cash from operations tends to fluctuate largely due to the timing of deliveries and product
purchases in the uranium and fuel services businesses.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In the first quarter of 2007, we generated $139&nbsp;million in cash from operations compared to $286
million in the first quarter of 2006. The decrease of $147&nbsp;million was related to the lower
revenues in the uranium, electricity and gold businesses as well as working capital requirements
related mainly to an increase in product inventories in the first quarter of 2007.
</DIV>

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


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">At March&nbsp;31, 2007, our total debt was $696&nbsp;million, representing a decrease of $9&nbsp;million compared
to December&nbsp;31, 2006. Included in the March&nbsp;31, 2007 balance sheet was $197&nbsp;million, which
represents our proportionate share of BPLP&#146;s capital lease obligation. At March&nbsp;31, 2007, our
consolidated net debt to capitalization ratio was 10%, compared to 12% at the end of 2006.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On January&nbsp;1, 2007, Cameco adopted the standards issued by the Canadian Institute of Chartered
Accountants relating to financial instruments, as described in note 3(b) of the financial review
for the year ended December&nbsp;31, 2006. These new standards have been adopted on a prospective basis
with no restatement of prior period financial statements. On January&nbsp;1, 2007, Cameco recognized all
of its financial assets and liabilities in the consolidated balance sheets according to their
classification. Any adjustment made to a previous carrying amount was recognized as an adjustment
to the balance of retained earnings at that date, or as the opening balance of &#147;accumulated other
comprehensive income,&#148; net of income taxes. Cameco has added a new statement to the consolidated
financial statements entitled &#147;Consolidated Statements of Shareholders&#146; Equity and Comprehensive
Income.&#148; For details of the specific accounting changes and their impacts, refer to note 1 of the
unaudited consolidated financial statements dated March&nbsp;31, 2007.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco sells most of its uranium and fuel services in US dollars, while most of its production of
uranium and fuel services are in Canada. As a result, these revenues are denominated mostly in US
dollars, while production costs are denominated primarily in Canadian dollars.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We attempt to provide some protection against exchange rate fluctuations by planned hedging
activity designed to smooth volatility. Hedging activities partly shelter our uranium and fuel

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco also has a natural hedge against US currency fluctuations, as a portion of its annual cash
outlays, including purchases of uranium and fuel services, is denominated in US dollars. The
influence on earnings from purchased material in inventory is likely to be dispersed over several
fiscal periods and is more difficult to identify.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">At each balance sheet date, Cameco calculates the mark-to-market value of all foreign exchange
contracts with that value representing the gain or loss that would have occurred if the contracts
had been closed at that point in time. We account for foreign exchange contracts that meet certain
defined criteria (specified by GAAP) using hedge accounting. Under hedge accounting, mark-to-market
gains or losses are included in earnings only at the point in time that the contract is designated
for use. At March&nbsp;31, 2007, the mark-to-market loss on all foreign exchange contracts was $18
million compared to a $34&nbsp;million loss at December&nbsp;31, 2006.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In all other circumstances, gains or losses in foreign currency derivatives are reported in

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We expect consolidated revenue for the second quarter of 2007 to be about 50% higher than in the
first quarter. This is due to anticipated higher sales volumes for uranium, conversion and
electricity as well as an increase in the realized price for uranium. The projection includes the
recognition of $47&nbsp;million in revenue previously deferred due to the product loan arrangements.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On April&nbsp;16, 2007, Cameco gave a termination notice to the counterparty for two of its three
product loan agreements. Under the two agreements, the loan facilities terminate 30&nbsp;days after the
date of notice. Therefore, Cameco will recognize a portion of the previously deferred revenues and
costs in its earnings during the second quarter of 2007. The amount of material Cameco is able to

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In 2007, Cameco expects consolidated revenue to grow by nearly 50% over 2006 due to higher revenue
from all business segments with the largest increase being in the uranium business. We now expect
uranium revenues to increase by approximately 90% due to stronger average realized prices under our
contracts relative to 2006. This projection for the uranium revenue is more favourable than
previously reported. The benefit of higher uranium revenue is offset slightly as Cameco anticipates
its share of Cigar Lake remediation expenses will be $32&nbsp;million in 2007 and will reduce pre-tax
earnings accordingly. For further details on the uranium business outlook, see &#147;Uranium Outlook for
the Year 2007&#148; later in this MD&#038;A.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We anticipate that revenue from the fuel services business will be about 15% higher than in 2006
due to an anticipated 3% increase in deliveries and a higher average realized selling price.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For 2007, we anticipate BPLP revenue to be about 18% higher than in 2006, almost entirely due to
higher expected realized prices. This outlook for BPLP assumes the B units will achieve a targeted
capacity factor in the low 90% range.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Gold production (100% basis) in 2007 is expected to total between 700,000 and 720,000 ounces up
from 587,000 ounces in 2006. Gold revenue is expected to increase by 20% to 25% in 2007 over 2006.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In the second quarter of 2006, we reported that Cameco had entered into standby product loan

of uranium hexafluoride (UF<SUB style="font-size: 85%; vertical-align: text-bottom">6</SUB>). Any borrowings are to be secured by letters of credit and

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As of March&nbsp;31, 2007, Cameco had not borrowed any material under the standby loan agreements.
However, regardless of whether any material is borrowed, we defer revenue recognition from sales to
the counterparties of the standby product loan agreements, up to the limit of the loans. This is in
accordance with GAAP. Cameco will recognize the deferred revenue and associated costs when the loan
agreements are terminated, or if drawn upon, when the loans are repaid and that portion of the
facility is terminated.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Accordingly, in the first quarter of 2007, Cameco has deferred revenue of $35&nbsp;million and the

to $183&nbsp;million, as a 23% increase in the realized selling price was more than offset by a 48%
decline in reported sales volumes. The timing of deliveries of uranium products within a calendar
year is at the discretion of customers. Therefore, our quarterly delivery patterns can vary
significantly. In 2006, the timing of deliveries through the year was unusual, with a heavier
weighting in the first quarter and lighter weighting in the fourth quarter. The increase in the
average realized price for the first quarter of this year was the result of higher prices under
market-related contracts due to a higher uranium spot price, which averaged $85.00 (US)&nbsp;per pound
compared to $38.96 (US)&nbsp;in the same quarter of 2006.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our total cost of products and services sold, including depreciation, depletion and reclamation
(DDR), decreased to $123&nbsp;million in the first quarter of 2007 from $188&nbsp;million in the first
quarter of 2006, as a 48% decline in the reported sales volume was partially offset by a 25% rise
in the unit cost of product sold. The unit cost of product sold increased primarily as a result of
higher costs for purchased uranium and higher royalty charges. The cost of purchased uranium has
trended upward with the rise in spot price, causing our carrying values for acquired material to
rise by about 25% since the first quarter of 2006. Royalty charges increase as the realized price
increases.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our earnings before taxes from the uranium business declined to $44&nbsp;million, from $89&nbsp;million in

12&nbsp;million pounds, nearly double those of the first quarter. Actual uranium deliveries will total 9
million pounds and, as the result of the termination of two of our product loan agreements, we
expect to recognize revenue on another 3&nbsp;million pounds. The unit cost of product sold is projected
to increase marginally from the first quarter due to higher royalty charges and higher costs for
purchased material.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Uranium Outlook for the Year 2007</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In 2007, the reported sales volume and associated revenue will be affected by the termination of
two of the three product loan agreements. Total uranium deliveries amounted to 36&nbsp;million pounds in
2006, while reported sales volume was 32&nbsp;million pounds due to the deferral of revenue as a result
of accounting for the product loans.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In 2007, we expect uranium deliveries to total 33&nbsp;million pounds. However, the reported sales
volume for revenue purposes is projected to be about 34&nbsp;million pounds due to the influence of the
product loan agreements. For 2007, we now expect our reported revenues to be higher than previously
estimated, about 90% greater than in 2006, due to a 75% increase in our realized price

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">(based on the March&nbsp;31, 2007 spot price of $95 (US)&nbsp;per pound) and a 6% increase in reported sales
volumes.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our average realized uranium price is anticipated to improve due to higher expected prices under
our current contracts relative to 2006. In addition, we expect almost 4&nbsp;million pounds of uranium
deliveries under our legacy contracts will be deferred from 2007 and thereby make available an
equivalent quantity for sale this year. The deferred quantities will be delivered in the future
over several years at legacy contract prices, based on negotiated schedules. Of the 4&nbsp;million
pounds deferred, 1.6&nbsp;million pounds have been deferred under an agreement that is considered to be
a derivative. Accordingly, the derivative will be recorded on the balance sheet in the second
quarter of 2007 at its fair value of approximately $11&nbsp;million with an offsetting charge to
earnings.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">To the extent that some portion or all of these 4&nbsp;million pounds of uranium are sold into new
market-priced contracts with deliveries in 2007, our average realized price will be positively
impacted, as current market prices are considerably higher than the legacy contract prices. For
purposes of this forecast, these 4&nbsp;million pounds are all assumed to be sold this year and are,
therefore, included in the 33&nbsp;million pounds of uranium deliveries projected for 2007 noted above.
At this point, approximately half of the 4&nbsp;million pounds has been committed to new contracts. Not
all of the remaining quantity will necessarily be delivered this year, in which case, the forecast
2007 price would be lower. Over the next several years (through as late as 2014), the quantities
being deferred this year will be delivered into their respective contracts at legacy prices. The
sale of some or all of the 4&nbsp;million pounds into new market-priced contracts will help mitigate the
financial impact resulting from the water inflow at Cigar Lake (which is discussed under &#147;Cigar
Lake&#148; later in this report).
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The impact of the sale of 4&nbsp;million pounds into new contracts and the later delivery of the
deferred pounds has been taken into account in the forecast of Cameco&#146;s average realized uranium
price in the table in the &#147;Uranium Price Sensitivity&#148; section below.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As mentioned previously, about three-quarters of currently contracted volumes are covered by supply
interruption language which provides Cameco with the right to reduce, defer or cancel volumes on a
pro-rata basis if we experience a shortfall in planned production or deliveries of purchases under
the highly enriched uranium agreement. This percentage will rise as old contracts expire. All
contracts contain standard force majeure language. The baseload contracts put in place to support
the development of Cigar Lake also contain similar provisions allowing Cameco to reduce, defer or
terminate deliveries in the event of any delay or shortfall in Cigar Lake production.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco&#146;s share of uranium production for 2007 is projected to increase slightly to 21.0&nbsp;million
pounds of U<SUB style="font-size: 85%; vertical-align: text-bottom">3</SUB>O<SUB style="font-size: 85%; vertical-align: text-bottom">8</SUB> from 20.9&nbsp;million in 2006. These quantities do not include
Inkai production, as the mine is not yet in commercial operation.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The unit cost of product sold is projected to increase by about 25% as a result of increased costs
for purchased material, higher royalty costs due to an increase in the realized price, the impact
of tiered royalty charges and increased production costs expected to be incurred in 2007.

<DIV style="font-family: 'Times New Roman',Times,serif">

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco did not pay provincial tiered royalties in 2006 and prior years due to the availability of
prescribed capital allowances that reduce uranium sales subject to tiered royalty. Cameco expects
its capital allowances to be fully exhausted during 2007 and, therefore, anticipates paying tiered
royalties in 2007. We currently estimate that tiered royalties will reduce net earnings by
approximately $10&nbsp;million in 2007. We will be eligible for capital allowances related to mine
expansion estimated to be about $325&nbsp;million once Cigar Lake commences production at which time we
will not be required to pay tiered royalties until the additional allowances are fully exhausted.
The capital allowance is calculated based on a prescribed formula. Tiered royalties are paid only
on sales of uranium produced at Saskatchewan mines.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The tiered royalty is calculated on the positive difference between the sales price per pound of
U<SUB style="font-size: 85%; vertical-align: text-bottom">3</SUB>O<SUB style="font-size: 85%; vertical-align: text-bottom">8</SUB> and the prescribed prices according to the following:

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As we have discussed in the past, our contracting objective is to secure a solid base of earnings
and cash flow to allow us to maintain our core asset base and pursue growth opportunities over the
long term. Our contracting strategy focuses on reducing the volatility in our future earnings and
cash flow, while providing protection against decreases in market price and retaining exposure to
future market price increases. This is a balanced approach, which we believe delivers the best
value to our shareholders over the long term.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our current portfolio reflects a 60/40 mix of market-related and fixed pricing (escalated by
inflation) mechanisms. Today our contracting is more focused on market-related pricing. Over the
past two years, 2005 and 2006, new contract volumes signed for deliveries in the future were
weighted more to market related pricing, with approximately 70% market related and 30% fixed.
Consequently, we expect this existing ratio to change over time. The overall strategy will continue
to focus on achieving longer contract terms of up to 10&nbsp;years or more, with floor prices that
provide downside protection, and retaining an adequate level of upside potential. In general, most
new offers include price mechanisms with a mix of market-related and fixed components. The
fixed-price component generally is at or above the industry long-term price indicator at the time
of offer and is adjusted by inflation. The market-related component includes a floor price
(escalated by inflation).
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco has a variety of supply sources including primary production, firm commitments for long-term
purchases, inventories of six months forward sales (equivalent to about 17&nbsp;million pounds,
including working inventory) and uranium from opportunistic purchases in the spot market.

demand and limited supply.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As has been the trend over the past three years, discretionary purchases continue to dominate, with
60% of the volumes purchased in the first quarter in this category. Generally discretionary
purchases are made by utilities to build inventory, traders for positioning and investment and
hedge funds to participate in the commodity. Due to limited supplies of U<SUB style="font-size: 85%; vertical-align: text-bottom">3</SUB>O<SUB style="font-size: 85%; vertical-align: text-bottom">8</SUB>,

<DIV style="font-family: 'Times New Roman',Times,serif">

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">First quarter production was lower than planned primarily as a result of mill process difficulties
in the first two months. Production rates improved in March and Cameco&#146;s share of production for
the second quarter of 2007 is expected to be 3.9&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>.
Cameco&#146;s share of production for 2007 is expected to be 13.1&nbsp;million pounds.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In 2006 and during the first two months of 2007, we encountered mill process difficulties
associated with higher levels of concrete dilution. Sand filters were installed in 2006 and while
this equipment has improved the clarity of the uranium solution, very fine particles carrying
organic material are not removed. The resulting organic carryover to the water effluent treatment
circuit resulted in effluent quality that required re-treatment in order to achieve acceptable
standards for release to the environment. In March, a hydrogen peroxide circuit was added to reduce
the concentration of organic material to acceptable levels. Full-scale testing of this equipment is
under way and initial results are positive. We are confident that with these changes, the Key Lake
mill will be able to process ore at target mill production rates.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As previously reported, we have applied to increase the annual licensed production capacity at both
the McArthur River mine and the Key Lake mill to 22&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>
(compared to the current 18.7&nbsp;million pounds). This application has been undergoing a screening
level environmental assessment (EA)&nbsp;as required by the Canadian Environmental Assessment Act with
the Canadian Nuclear Safety Commission (CNSC)&nbsp;as the responsible authority.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The CNSC has focused on an evaluation of the longer-term environmental impact of low levels of
selenium and molybdenum in the Key Lake mill&#146;s effluent and the concentration of these substances
in the downstream receiving environment.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco has developed an action plan to further reduce selenium and molybdenum discharges in the
mill effluent. While we believe that the current level of control protects the environment and is
consistent with past EAs of the Key Lake operation, we also recognize that improvements can be made
to further reduce levels of these two metals. In December&nbsp;2006, we finalized this action plan in
consultation with the CNSC.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">At a commission level hearing in January&nbsp;2007, the CNSC considered a proposed licence amendment for
the Key Lake mill to implement this plan. This amendment was approved in March&nbsp;2007 and the first
phase of plan implementation is under way with completion targeted at the end of the year. Reducing
the current level of these metals discharged to the environment is expected to help advance the EA
to increase the annual licensed production limit at the McArthur River mine and the Key Lake mill.
We remain confident that we can incrementally increase production levels with minimal environmental
effect.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In addition to obtaining approval for the EA, we need to transition to new mining zones at McArthur
River and to implement various mill process modifications at Key Lake in order to sustain increased
production levels. Mine planning, development and freeze-hole drilling for the McArthur River
transition is ongoing.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Progress on freeze hole drilling in advance of development for two future mining zones improved
from 2006 results, with targeted rates achieved for the first quarter of 2007. Another freeze-hole

through the drill holes, sealing off the inflow with grout, and drilling dewatering holes.
Subsequent phases include dewatering the mine, ground freezing in the area of the inflow, restoring

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Concrete will be poured in the area near the rockfall to seal off the inflow area and is being
poured in a nearby tunnel to provide reinforcement. About 2,200 cubic metres of concrete have been
poured in the reinforcement area and it is anticipated the pouring of the concrete for
reinforcement will be completed within two to three weeks. We are working with our regulators to
provide the information necessary to secure approval for the concrete plug required to seal off the
inflow area. Once we receive regulatory approval, we will begin pouring concrete in the inflow
area. The concrete mixture is designed to harden under water and will be poured in successive
layers.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco received regulatory approval in March to drill the four larger diameter holes planned for
mine dewatering and still requires approval to install the pumps. We have the first hole to a depth
of 480 meters and are currently drilling the second hole. After we gain experience with drilling
the first couple of dewatering holes, we will be able to provide an estimate for the completion of
all four holes. We have secured access to all drilling equipment required for the remediation work.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We expect to complete the work necessary to seal off the water inflow in the third quarter of 2007,
provided that all necessary regulatory approvals are received in time to carry out the work, the
current pace of placing concrete is maintained, and the concrete solidifies as planned to provide
reinforcement and prevent or reduce water inflow sufficiently to enable mine dewatering. The
effectiveness of the plug will not be known until dewatering is under way.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As previously discussed, the second phase of remediation includes dewatering the underground

including mill modifications at Rabbit Lake and McClean Lake (where the uranium will be processed),
is currently estimated at $274&nbsp;million. Adding this cost estimate to the $234&nbsp;million that Cameco
has already spent on Cigar Lake construction brings Cameco&#146;s share of total construction costs to
develop the project to about $508&nbsp;million.

Consequently, we sell more uranium than we produce from our minesites. Cameco has multi-year
purchase agreements in place, the most significant being our purchase of uranium derived from
blended-down Russian highly enriched uranium (HEU), under which we expect to purchase about 7
million pounds uranium equivalent annually over the period covered by the above table. We also have
other committed term purchase arrangements for smaller annual quantities. In addition, we make
short-term and spot market purchases.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On the Dawn Lake project, we continued pre-feasibility activities on the 11B zone with completion
expected during April. We completed 18 drill holes totalling about 3,100 metres on the Collins
Creek deposit focusing on areas not accessible during the summer. Included in this total are six
holes, which were abandoned due to excessive deviation in the overburden or drilling problems in
the sandstone. Six of the remaining 12 holes contained significant mineralization. One hole
returned two separate intersections; a zone in the lower sandstone intersected 1.1%

completed and the 3D seismic survey initiated. The service shaft pilot hole was completed to 776
metres while the return airshaft pilot drill hole was drilled to 650 metres. The ground conditions
of both holes are excellent, with minimal fracturing and competent rocks. No other drilling was
undertaken in the Millennium area. The 3D seismic survey over the Millennium area is currently
under way and was about 35% complete at quarter end.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On the McArthur River project, drilling was focused north of the underground workings. A total of
about 3,500 metres were completed in three pilot holes, three offcut holes and one historic hole
was deepened. Encouraging mineralization continues to be intersected nearly 1,500 metres north of
the Pollock shaft.

about 3,300 metres were completed. Three holes, totalling 711 metres were drilled along the Key
Lake fault southwest of the Gaertner and Deilmann uranium deposits. Although no significant
mineralization was intersected, elevated radioactivity was encountered in the basement lithologies
of both areas tested. Cameco&#146;s ownership of the Cree Zimmer Joint Venture is 83.335%.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As in the case of the deferred uranium revenue, the timing of cash receipts on the deferred revenue
is the same as on any other sale and is unaffected by the accounting treatment for the revenue. As
a result, cash flows are not impacted by the deferral. Cameco will recognize the deferred revenue
and associated costs when the loan agreements are terminated, or if drawn upon, when the loans are
repaid and that portion of the facility is terminated.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In the first quarter of 2007, revenue from our fuel services business was unchanged at $44&nbsp;million
compared to the same period in 2006, as the impact of a decline in reported sales volumes was
offset by an increase in the realized price. Most conversion sales are at fixed prices and have not
yet fully benefited from the significant increase in UF<SUB style="font-size: 85%; vertical-align: text-bottom">6</SUB> spot prices.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Total cost of products and services sold, including DDR, was also unchanged at $35&nbsp;million compared
to 2006. The effect of the lower volume was offset by higher costs, which are related to the mix of
products delivered in 2007. A higher proportion of sales were attributable to fabrication in 2007.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For the second quarter of 2007, our fuel services revenue is projected to be about 50% higher than
that of the first quarter due to an expected increase in deliveries. It is anticipated that the
average realized price will be slightly lower. The projection includes the recognition of $3
million in revenue previously deferred due to the product loan arrangements referred to above.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco expects 2007 revenue from the fuel services business to be nearly 15% higher than in 2006
due to an anticipated 3% increase in deliveries and an improvement in the average realized selling
price.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Reported sales volume from fuel services in 2007 is expected to total 19.1&nbsp;million kgU, down
from the previous estimate of 20.2&nbsp;million kgU, due to deferrals in deliveries under existing
contracts. This compares to sales of 18.5&nbsp;million kgU in 2006. The cost of product sold is expected
to increase due to the higher volume. On a per unit basis, product costs are projected to be
similar to 2006.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For the first quarter of 2007, BPLP&#146;s electricity revenue decreased to $290&nbsp;million from $334
million over the same period in 2006 due to the lower output, partially offset by a 7% increase in
the realized selling price.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The realized price achieved from a mix of contract and spot sales averaged $54 per MWh in
the quarter, up from $50 per MWh in the same quarter of 2006. During the first three months, the
Ontario electricity spot price averaged $53 per MWh, compared to $51 per MWh in the first quarter
of 2006.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">To reduce its exposure to spot market prices, BPLP has a portfolio of fixed-price sales contracts.
During the first quarter of 2007, about 47% of BPLP output was sold under fixed-price contracts,
about the same as in the first three months of 2006.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco provides guarantees to customers under these contracts of up to $72&nbsp;million. At March&nbsp;31,
2007, Cameco&#146;s actual exposure under these guarantees was $1&nbsp;million. In addition, Cameco has
agreed to provide up to $133&nbsp;million in guarantees to CNSC and $58&nbsp;million to Ontario Power
Generation Inc. (OPG)&nbsp;to support other Bruce Power commitments. Of these amounts, corporate
guarantees have been issued for $24&nbsp;million to the CNSC and $58&nbsp;million to OPG at March&nbsp;31, 2007.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Operating costs (including amortization) were $259&nbsp;million in the first quarter of 2007, compared
with $182&nbsp;million in the same period of 2006. This increase was primarily attributable to
maintenance costs associated with the outage of unit 6 during the quarter. About 95% of BPLP&#146;s
operating costs are fixed. As such, most of the costs are incurred whether the plant is operating
or not. On a per MWh basis, the operating cost in the first quarter of 2007 was $48, compared to
$28 in the first quarter of 2006.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>BPLP Outlook Considerations</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The results from BPLP are influenced by a number of factors including operating performance, costs
and realized price. The operating performance is affected by planned and unplanned outages. Total
costs are relatively insensitive to changes in output, as about 95% of BPLP&#146;s operating costs are
fixed and most of the costs are incurred whether the plant is operating or not. As a result, unit
costs are dependent on output and subject to large variability if output changes. Cameco reports
BPLP costs net of recoveries. Realized prices are made up of a mixture of sales under contract at
fixed prices and sales in the Ontario spot electricity market. The Ontario spot price is dependent
on a number of factors such as the supply of and demand for electricity. Demand for electricity is
very sensitive to Ontario weather patterns.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For the second quarter of 2007, we anticipate BPLP revenue to be about 20% higher than in the first
quarter, as the result of higher generation. The average realized price is expected to be similar
to that of the first quarter.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>BPLP&#146;s Outlook for 2007</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In 2007, capacity factors for the B units are expected to average in the low 90% range similar to
the 91% achieved in 2006. After investing significant capital on refurbishing the B units over the
past few years, we anticipate continued reliable performance with the only planned outage being the
one completed in April.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For 2007, the average unit cost is expected to rise to $34 per MWh compared to $31 in 2006. Total
costs are expected to rise by 12% in 2007 over 2006. The increase is due primarily to a rise in
staff costs, operating and maintenance costs for heavy water treatment and fuel costs as well as
lower incidental recoveries compared to 2006. In addition, higher amortization expenses are
expected in 2007, reflecting the addition of the new administration building and other capital
projects.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For 2007, we anticipate BPLP revenue to be 18% higher than in 2006, almost entirely due to higher
expected realized prices, which are made up of fixed contract prices and Ontario spot market
electricity prices. The spot prices are very sensitive to Ontario weather patterns. In 2006, the
average realized price was $48 per MWh.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The second quarter and 2007 outlook for BPLP assumes that the B units will achieve their targeted
capacity factor and that there will be no significant changes in current estimates for costs and
prices.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Electricity Price Sensitivity Analysis</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For the remainder of 2007, BPLP has about 6 TWh under contract, which would represent about 28% of
Bruce B generation at its planned capacity factor. For the remainder of 2007, a $1.00 per MWh
change in the spot price for electricity in Ontario would change Cameco&#146;s after-tax earnings from
BPLP by about $3&nbsp;million.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As part of its Bruce B power uprate project, BPLP had initiated plans to refuel the B units with
modified fuel containing slightly enriched uranium (SEU)&nbsp;beginning in 2008. Until recently, all
four of the B units were operating at 90% of maximum power, based on an operating limitation
imposed by the CNSC. The operating limitation ensures that necessary safety margins are maintained.
The use of the modified fuel is intended to allow the reactors to operate closer to

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">design capacity, while maintaining safety margins. Approval is required from the CNSC to operate
the B units with the modified fuel.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In early 2007, Bruce Power, in consultation with the CNSC, revised its fuel deployment strategy and
is now developing plans to load the modified fuel into the Bruce A reactors prior to loading such
fuel into the B reactors, subject to the finalization of all commercial arrangements and Bruce
Power board approvals. This will delay the power uprate program at Bruce B.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">BPLP has successfully taken other steps to partially restore power ratings at the B units. In 2004,
unit 6 received CNSC approval to operate at 93% on the basis of improved safety margins attributed
to completion of the first phase of a fuel core reordering program. Units 7 and 8 have since
achieved this uprate to 93%. Unit 5 is expected to receive this uprate by 2008.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For the three months ended March&nbsp;31, 2007, revenue from our gold business decreased by $11&nbsp;million
to $96&nbsp;million compared to the first quarter of 2006. The decline in revenue was due to lower
production, which offset the benefit of a higher realized gold price. Production at Kumtor
continues to be impacted by the pit wall movement that occurred in July&nbsp;2006. The realized price
for gold rose to $645 (US)&nbsp;per ounce in the quarter compared to $542 (US)&nbsp;per ounce in the first
quarter of 2006, due to higher spot prices.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Kumtor&#146;s production was 66,000 ounces compared to 89,000 ounces in the first quarter of 2006. This
decrease was due to reduced throughput and a lower mill head grade that averaged 2.2 grams per
tonne (g/t) in the quarter compared to 2.4 g/t in the same period in 2006.

of gold. At Kumtor, production for the full year 2007 is expected to be about 450,000 to 460,000
ounces of gold. Recently, at Kumtor, a minor slope movement has been detected in the waste dump
above the central pit and SB zone highwall. The waste dump slope is currently designed at a
33-degree angle. Geotechnical drilling and analysis is underway to determine whether a lower design
slope angle is required to stabilize the waste dump and if so, the effect on future production. At
Boroo, on a 100% basis, we expect production in the range of 250,000 to 260,000 ounces of gold in
2007. Gold revenue is expected to increase by 20% to 25% in 2007 over 2006. This outlook for the
gold business is based on the following key assumptions:

Currently this action has no legislative effect and does not interfere with Centerra&#146;s operations

discussions regarding a number of issues concerning Kumtor. The positive resolution of these issues
would help to provide a stable and favourable operational environment for and an improved
investment climate in the Kyrgyz Republic. If the issues between the Kyrgyz Republic and Cameco and
Centerra are not resolved to their mutual satisfaction, the risks to Centerra and Cameco will

begun international arbitration with the government to recover the disputed amounts. The total
amount in dispute for 2006 is about $7&nbsp;million (US).

Akaev in 2005. None of these inquiries and investigations has resulted in any material negative
effect on Kumtor, and to Centerra&#146;s knowledge, are inactive or are currently not being pursued by

January&nbsp;15, 2007 that the Boroo stability agreement will be terminated unless the alleged
violations are cured within 120&nbsp;days. Centerra responded to the minister that in all cases it has
either remedied the alleged violations or strongly disputes that a violation exists. Subsequent
correspondence with the minister of finance indicates that most of the outstanding matters in
dispute have been resolved to the government&#146;s satisfaction. The minister has asserted that Boroo
is subject to tax at the rate of 20% effective January&nbsp;1, 2007, rather than March&nbsp;1, 2007, on the
basis that commercial production, and therefore the three-year tax exemption applicable to Boroo
under its Stability Agreement, began on January&nbsp;1, 2004 rather than March&nbsp;1, 2004. Centerra
disputes the Minister&#146;s claim. The amount in issue is approximately $4&nbsp;million for the full year
2007. Centerra believes that this and other remaining matters will be resolved through further
discussions with the Ministry of Finance or as part of the continuing negotiations on the Boroo
Stability Agreement. At the request of the parliament, the Mongolian Accounting Chamber is
currently conducting a comprehensive audit of Centerra&#146;s operations in the country.

interest in those strategic deposits in respect of which exploration was funded privately or 50%

February&nbsp;6, 2007, Parliament designated the Boroo deposit as strategic but resolved that the state
would take no interest, as the deposit would continue to be subject to the terms of the existing

LLC if CGM did not complete a feasibility study by December&nbsp;31, 2005. CGM completed a feasibility
study in December&nbsp;2005. In early 2006, Gatsuurt LLC informed Centerra that it does not believe that
CGM complied with its obligation. Gatsuurt LLC has recently begun proceedings in the Mongolian
National Arbitration Court (MNAC)&nbsp;alleging non-compliance by CGM and seeking the return of the
licence. CGM intends to contest the jurisdiction of the arbitration court and continues to believe
that the Gatsuurt LLC claim is without merit. However, CGM&#146;s challenges may be unsuccessful,
resulting in the MNAC taking jurisdiction over the dispute. Any decision of the MNAC may be final

possible new unit at the Grand Gulf plant in Mississippi. An ESP permit, which certifies that the
site is safe and environmentally suitable for a new nuclear unit, remains valid for 20&nbsp;years. The
next step is to prepare an application for a combined construction and operating licence (COL),
which Entergy plans to submit in 2008. This brings the number of ESP&#146;s granted to two. In the US,
15 entities are proceeding with applications for either an ESP or a COL for potential new nuclear
power plants, with as many as 33 new units under consideration.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The US utility, TXU announced the cancellation of eight coal-fired power stations when it agreed to
be acquired by two private equity firms. The TXU projects had been the subject of intense
environmental debate. TXU will now focus on new nuclear power and expects to file the necessary
applications with the NRC for a COL for two large units at its Comanche Peak station in Texas in
2008. TXU has stated they ultimately want to build two to five new reactors.

achieved initial criticality on February&nbsp;26, 2007. Once Unit 3 reaches commercial operation,
India&#146;s total nuclear capacity will increase from 3,900 MWe to 4,120 MWe, which would enable the
nation to meet its nuclear capacity goal for its 2002 to 2005 five-year plan. Construction on Unit
3 began five years ago in March&nbsp;2002. Unit 4 at Kaiga is nearing completion and is expected to
achieve initial criticality in the next few months.

six 1,650 MWe European pressurised reactors at a site in India. Depending upon the successful

Nuclear Power in Europe&#148;. Overall, the report finds that nuclear power will continue to play an
important role in providing stable energy for European countries through the current fleet and

providing power on a cost-competitive basis, and that there is the potential for nuclear to be an
important non-carbon emitting source of power.

market value of the facilities, and interest is payable on the market value of any amounts drawn at
rates ranging from 4.0% to 5.0%. Any borrowings will be secured by letters of credit and are
repayable in kind.

2007 and was approximately $544&nbsp;million (US). As at March&nbsp;31, 2007, the company did not have any
loan amounts outstanding under the facilities.

comprehensive income, as described in note 3(b) of the consolidated financial statements

previous carrying amount was recognized as an adjustment to the balance of retained
earnings at that date or as the opening balance of accumulated other comprehensive
income (&#147;AOCI&#148;), net of income taxes. Cameco has added a new statement to the

    <TD>The majority of revenues at Cameco are derived from the sale of uranium products,
electricity through its investment in Bruce Power L.P. (&#147;BPLP&#148;), and gold through its
investment in Centerra Gold Inc. (&#147;Centerra&#148;). Cameco&#146;s uranium product financial
results are closely related to the long and short-term market price of uranium sales
and conversion services. Prices fluctuate and can be affected by demand for nuclear
power, worldwide production and uranium levels, and political and economic conditions
in uranium producing and consuming countries. BPLP&#146;s revenue from electricity is
affected by changes in electricity prices associated with an open spot market for
electricity in Ontario. Centerra&#146;s gold revenue is largely dependent on the market
price of gold, which can be affected by political and economic factors, industry
activity and the policies of central banks with respect to their level of gold held
as reserves. Financial results for Cameco are also impacted by changes in foreign
currency exchange rates and other operating risks. Finally, certain financial assets
are subject to credit risks including cash and securities, accounts receivable, and
commodity and currency instruments.</TD>

    <TD>The purpose of hedging transactions is to modify Cameco&#146;s exposure to one or more
risks by creating an offset between changes in the fair value of, or the cash flows
attributable to, the hedged item and the hedging item. Hedge accounting ensures that
the offsetting gains, losses, revenues and expenses are recognized to net earnings in
the same period or periods. When hedge accounting is appropriate, the hedging
relationship will be designated as a fair value hedge, a cash flow hedge, or a
foreign currency risk hedge related to a net investment in a self-sustaining foreign

relationships between hedging instruments and hedged items, as well as its risk
management objective and strategy for undertaking various hedge transactions. The
process includes linking all derivatives to specific assets and liabilities on the

formally assesses, both at the inception and on an ongoing basis, whether the

    <TD>Derivatives may be embedded in other financial instruments (the &#147;host instrument&#148;).
Prior to the adoption of the new standards, most embedded derivatives were not
accounted for separately from the host instrument except in cases such as Cameco&#146;s
unsecured convertible debentures where the fair value of the option component was
reflected separately in contributed surplus. Under the new standards, embedded
derivatives are treated as separate derivatives when their economic characteristics
and risks are not clearly and closely related to those of the host instrument, the
terms of the embedded derivative are the same as those of a stand-alone derivative,
and the combined contract is not held for trading or designated at fair value. These
embedded derivatives are measured at fair value with subsequent changes recognized in
gains or losses on derivatives within interest and other on the consolidated

    <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 letter to British Energy Limited and British Energy International Holdings
Limited (collectively, &#147;BE&#148;) requesting, amongst other things, indemnification for
breach of a representation and warranty contained in the February&nbsp;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. A decision to proceed with arbitration has been made but formal
commencement of proceedings has not taken place because counsel for the Consortium and
BE have yet to agree on the composition of the arbitration panel.</TD>

    <TD>In anticipation of this claim, BE issued on February&nbsp;10, 2006 and then served on Ontario
Power Generation Inc. and Bruce Power LP a Statement of Claim. This Statement of Claim
seeks damages for any amounts that BE is found liable to pay to the Consortium in
connection with the Unit 8 steam generator arbitration described above, damages in the
amount of $500,000,000, costs and pre and post judgment interest amongst other things.
This action is in abeyance pending further developments on the Unit 8 steam generator
arbitration.</TD>

    <TD>On March&nbsp;26, 2007 the Parliament of the Kyrgyz Republic accepted in the first
reading and returned to committee for further deliberation draft legislation that among
other things provides for the transfer of gold deposits (including Kumtor Gold Company)
to a state-owned entity. If enacted the law would therefore substantially harm the
rights of Centerra. Currently this action has no legislative effect and does not
interfere with Centerra&#146;s operations in the country. If the issues between Cameco and
Centerra, and the Kyrgyz Republic are not resolved to their mutual satisfaction, the
risks to Centerra will increase. Centerra and Cameco expect to re-engage in
discussions with the new government regarding the Kumtor Project as soon as the
existing political confrontation between the current administration and the opposition
is resolved.</TD>

    <TD>Pursuant to an agreement between Centerra Gold Mongolia Limited (&#147;CGM&#148;) and
Gatsuurt LLC, an unrelated Mongolian company, under which CGM acquired the Gatsuurt
licences, CGM agreed to transfer the principal licence covering the Gatsuurt property
to Gatsuurt LLC if CGM did not complete a feasibility study by December&nbsp;31, 2005. CGM
completed a feasibility study in 2005. Gatsuurt LLC informed Centerra that it did not
believe that CGM complied with its obligation and filed a claim in the Mongolian
national arbitration court alleging non-compliance by CGM and seeking the return of the
principal licence for the Gatsuurt property. CGM intends to contest the jurisdiction of
the arbitration court and continues to believe that the terms of this agreement have
been fully met and that the Gatsuurt LLC claim is without merit.</TD>

    <TD>The Ministry of Finance has alleged certain tax-related violations by Boroo Gold Company
LLC (&#147;Boroo&#148;) and notified it on January&nbsp;15, 2007 that the Boroo stability agreement
will be terminated unless the alleged violations are cured within 120&nbsp;days. Centerra
responded to the Minister that in all cases it has either remedied the alleged
violations or strongly disputes that a violation exists. On February&nbsp;13, 2007, Centerra
received a reply from the Minister of Finance re-iterating the allegations of
violations. The potential impact of this claim is not determinable at this time.
Centerra has responded that in all cases it has either remedied the alleged violations
or strongly disputes that a violation exists. Centerra believes that this dispute will
be fully resolved as part of the negotiations on the Boroo and Gatsuurt agreements.</TD>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>Cameco Corporation </B>issued a correction to the second quarter outlook contained in its recent news
release titled &#147;Cameco Reports Lower Q1 Results but Expects Much Higher 2007 Revenue.&#148;
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The outlook section should have noted that we expect consolidated revenue for the second quarter of
2007 to be about 50% higher than in the first quarter. The outlook section incorrectly referred to
earnings instead of revenue. Cameco does not provide guidance on consolidated earnings.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>Profile</B><BR>
Cameco, with its head office in Saskatoon, Saskatchewan, is the world&#146;s largest uranium producer, a
significant supplier of conversion services and one of two Candu fuel manufacturers in Canada. The
company&#146;s competitive position is based on its controlling ownership of the world&#146;s largest
high-grade reserves and low-cost operations. Cameco&#146;s uranium products are used to generate clean
electricity in nuclear power plants around the world, including Ontario where the company is a
partner in North America&#146;s largest nuclear electricity generating facility. The company also
explores for uranium in North America and Australia, and holds a majority interest in a mid-tier
gold company. Cameco&#146;s shares trade on the Toronto and New York stock exchanges.

unexpected geological or hydrological conditions; adverse mining conditions; political risks
arising from operating in certain developing countries; terrorism; sabotage; a possible
deterioration in political support for nuclear energy; changes in government regulations and
policies, including tax and trade laws and policies; demand for nuclear power; replacement of
