                                  OLP VALUATION

APPROACH

- -        Based on a capitalized EBITDA approach.

- -        Net present value of the tax attributes separately considered.

CAPITALIZED EBITDA APPROACH

- -        Revenues and expenses are relatively predictable/constant in this type
         of business.

- -        After normalization adjustments, EBITDA has been in the range of $46
         million to $48 million during the last three years. Normalized EBITDA
         for 2004 is projected at $45 million.

             -    EBITDA is based on information provided to us by MDS via PWC
                  and includes additional costs related to the carve out of the
                  OLP of approximately $275,000 per annum.

- -        Public companies multiples are currently in the range of 10.5x to 11.0x
         EBITDA on a trailing-twelve month basis.

- -        Valuation based on normalized EBITDA of $45 million and observed public
         company multiples is as follows:

             -    $ 45 million x 10.5 = $472.5 million

             -    $ 45 million x 11.0 = $495.0 million.

TAX ATTRIBUTES

- -        Based on a pre-tax profit of about $41 million, net present value using
         approximately $315 million in tax attributes and a discount rate of 10%
         is approximately $95 million.

                               WARRANTS VALUATION

TERMS

- -        Vest at 333,333 per month (based on 4 million warrants) between May 25,
         2004 and April 24, 2005.

             -    Consideration in proposed transaction relates to 2.5 million
                  of the 4.0 million on a pro-rata basis.

- -        Exercisable at $1.00 per warrant and expire three years after vesting.

INTRINSIC VALUE

- -        Intrinsic value = Current share price - exercise price

- -        Based on a stock price of $1.60, warrants have an intrinsic value of
         $0.60 per share or $1.5 million in aggregate (i.e., 2,500,000 @$0.60).

FAIR MARKET VALUE

- -        Used Black-Scholes option pricing model adjusted to account for the
         dilutive impact of the warrants.

- -        Valuation highly sensitive to volatility used.

             -    Volatility used in pricing of warrants in the past for
                  accounting purposes has been 100%.

- -        At $1.60 share price, warrants have a fair market value of
         $1.18/warrant or total of $2.9 million using 100% volatility.

                                  BPP VALUATION

APPROACHES

- -        Considered both the discounted cash flow ("DCF") approach and market
         capitalization approach.

             -    More emphasis should be placed on discounted cash flow
                  approach, since:

                      -     Less information available in the market place
                            (i.e., projections not made publicly-available).

                      -     No analyst followings; unlikely value based on
                            intrinsic valuation; very speculative

DISCOUNTED CASH FLOW APPROACH

- -        Based on the following:

             -    Projections provided by management and a discount rate of 25%
                  to 30%.

                      -     KPMG modeled cash taxes, including $60 million of
                            UCC that would remain with BPP.

             -    Redundant assets of $2.5 million

             -    An assumed value relating to other products in the pipeline of
                  $8-10 million.

             -    Value of the existing tax losses assumed to equal implied
                  value of tax attributes in the proposed transaction.

             -    Outstanding debt of $20 million.

MARKET CAPITALIZATION APPROACH

- -        Based on a $1.60 share price and 54 million shares, value implied in
         market for BPP business is approximately $86 million.

[KPMG LOGO]   Draft for Discussion      10                        [HEMOSOL LOGO]



                                 TAX ATTRIBUTES

GENERAL

- -        On a weighted-average basis, there exists approximately $324 million of
         tax attributes as at the end of 2003 available to be effectively
         transferred to MDS under the proposed transaction. Key assumptions are
         as follows:

             -    We have assumed that $60 million will be assigned to the
                  assets of the BPP. As a result, this amount will not remain in
                  old Hemosol and, therefore, will not be effectively
                  transferred to MDS.

             -    We have excluded $10 million in financing costs since we
                  understand that MDS has indicated that there is significant
                  risk associated with the validity of a certain portion of
                  these costs.

- -        Statutory tax rates are as follows:

             -    Federal - 22%

             -    Provincial - 14%



                                                      FEDERAL     PROVINCIAL

                             TAX ATTRIBUTES (CONT'D)

VALUATION OF TAX ATTRIBUTES

- -        Based on our review of publicly-announced transactions and confidential
         transactions, tax attributes have recently transacted in the range of
         5-8 cents per dollar of tax attribute.

             -    Confidential transactions include those in which KPMG has
                  advised. Through discussions with E&Y in the capacity as tax
                  advisors to Hemosol, we understand that above range is also
                  consistent with that observed by them.

IMPLIED VALUE OF TAX ATTRIBUTES

- -        Based on value assigned to other consideration, the proposed
         transaction implies a value for the tax attributes as follows:

             -    Under DCF approach (arrow) $16.6 million to $17.8 million, or
                  5.1-5.5 cents per dollar of tax attribute

             -    Under market capitalization approach (arrow) $14.6 million to
                  $14.7 million, or 4.5 cents per dollar of tax attribute.

- -        Based on the above, the implied value of the tax attributes is at the
         low end of the range observed in other transactions.

             -    As indicated earlier, more emphasis should be placed on the
                  valuation derived under the DCF approach.

                             OVERALL CONSIDERATIONS

OVERALL CONSIDERATIONS IN ASSESSING THE FAIRNESS OF THE PROPOSED TRANSACTION

- -        As previously indicated, the value implied by the tax attributes
         appears to be at the low end of observed transactions. However, we note
         the following:

             -    The proposed transaction involves the monetization of over
                  $300 million in tax attributes - a very significant amount
                  rarely observed in transactions. Given the limited number of
                  potential users of attributes of this magnitude and/or the
                  period of time it would take a company to use up this amount,
                  we would expect the price per dollar of tax attribute to be at
                  or near the low end of observed transactions.

             -    The proposed transaction involves the monetization of all of
                  Hemosol's tax attributes (except a portion of the UCC balance)
                  in a single transaction. Alternate tax monetization structures
                  could involve more than one transaction, would likely be more
                  costly to Hemosol and entail completion risk with respect to
                  future deals. These factors would likely cause the price of
                  the Hemosol shares to trade at a discount to the price that
                  would otherwise exist should the proposed transaction close.

             -    Unlike potential alternative tax monetization structures,
                  Hemosol will receive cash and invest it in the existing
                  operations with the expectation of earning profits sometime in
                  the future. Alternative transactions may involve the
                  discontinuance of the existing operations and the use of the
                  cash to fund the acquisition of unrelated businesses.

- -        The fact that the Class A shares to be received in respect of the
         equity interest in the OLP are not to be traded on an active market,
         but instead will be traded OTC.

             -    As a result, it may take longer for a shareholder to dispose
                  of their interest.

             -    It is expected, however, that the Class A shares will pay a
                  dividend on a not less than annual basis, therefore providing
                  some liquidity to shareholders. Dividends on the Class A
                  shares are to be declared on a pro-rata basis with the Class B
                  shares (which are to be held by MDS).

                       OVERALL CONSIDERATIONS & CONCLUSION

OVERALL CONSIDERATIONS IN ASSESSING THE FAIRNESS OF THE PROPOSED TRANSACTION
(CONT'D)

- -        The fact that the forgiveness of the warrants reduces the potential for
         further dilution of Hemosol in the future. Should additional cash be
         required in the future, the shares that would have otherwise been
         issued under these warrants could be used to obtain more financing
         and/or financing on a less costly and/or non-dilutive basis.

- -        We understand that the proposed transaction may give rise to a taxable
         dividend to U.S. shareholders equal to their pro-rata share of any
         earnings & profits ("E&P") generated, assessed or reported for 2004.

             -    In the worst case, we understand that this dividend will be
                  approximately 20 cents per share - a 6-7 cents tax impact
                  assuming a 30-35% personal tax rate.

             -    We further understand, however, that there is a very low risk
                  of actual E&P being generated, assessed or reported.

CONCLUSION

- -        Based upon and subject to the foregoing and such matters as we
         considered relevant, KPMG is of the opinion that the proposed
         transaction is fair, from a financial point of view, to the
         shareholders of Hemosol other than MDS.
