                  TRUST UNDER THE EMPLOYMENT AGREEMENTS BETWEEN
                     FAIRCHILD SEMICONDUCTOR CORPORATION AND
               KIRK P. POND, JOSEPH R. MARTIN, AND DANIEL E. BOXER

         (a)      THIS AGREEMENT, made this 8 day of September, 2004, by and
between FAIRCHILD SEMICONDUCTOR CORPORATION, a corporation organized under the
laws of the State of Delaware ("Company"), and H.M. PAYSON & CO., a Maine
nondepository trust company ("Trustee");

         (b)      WHEREAS, Company has entered into the Employment Agreements
with Kirk P. Pond, Joseph R. Martin, and Daniel E. Boxer ("Executives") listed
in Appendix A, under which it is obligated to provide lifetime health coverage
(hereinafter called the "Agreements");

         (c)      WHEREAS, Company has incurred or expects to incur liability
under the terms of such Agreements with respect to each Executive and his family
members who would be eligible dependents under the Company's group health plan
("Covered Individuals");

         (d)      WHEREAS, Company wishes to establish a trust (hereinafter
called "Trust") and to contribute to the Trust assets that shall be held
therein, subject to the claims of Company's creditors in the event of Company's
Insolvency, as herein defined, until paid to or for the benefit of Covered
Individuals in such manner and at such times as specified herein and in the
Agreements;

         (e)      WHEREAS, it is the intention of the parties that this Trust
shall constitute an unfunded arrangement and shall not affect the status of each
of the Agreements as an unfunded arrangement maintained for the purpose of
providing welfare benefits for a member of a select group of management or
highly compensated employees for purposes of Title I of the Employee Retirement
Income Security Act of 1974 ("ERISA");

         (f)      WHEREAS, it is the intention of Company to make contributions
to the Trust to provide itself with a source of funds to assist it in the
meeting of its liabilities under the Agreements;

         NOW, THEREFORE, the parties do hereby establish the Trust and agree
that the Trust shall be comprised, held and disposed of as follows:

                                    SECTION 1
                             ESTABLISHMENT OF TRUST

         (a)      Company hereby deposits with the Trustee in trust Two Million
Two Hundred and Fifty Thousand Dollars ($2,250,000), which shall become the
principal of the Trust to be held, administered and disposed of by Trustee as
provided in this Trust Agreement.

         (b)      The Trust hereby established shall be irrevocable, subject to
Section 12(b) below.

<PAGE>

         (c)      The Trust is intended to be a grantor trust, of which Company
is the grantor, within the meaning of subpart E, part I, subchapter J, chapter
1, subtitle A of the Internal Revenue Code of 1986, as amended, and shall be
construed accordingly.

         (d)      The principal of the Trust, and any earnings thereon, shall be
held separate and apart from other funds of Company and shall be used
exclusively for the uses and purposes of Covered Individuals and general
creditors as herein set forth. Covered Individuals shall have no preferred claim
on, or any beneficial ownership interest in, any assets of the Trust. Any rights
created under the Agreements and this Trust Agreement shall be mere unsecured
contractual rights of Covered Individuals against Company. Any assets held by
the Trust will be subject to the claims of Company's general creditors under
federal and state law in the event of Insolvency, as defined in Section 3(a)
herein.

         (e)      Company, in its sole discretion, may at any time, or from time
to time, make additional deposits of cash or other property in trust with
Trustee to augment the principal to be held, administered, and disposed of by
Trustee as provided in this Trust Agreement. Neither the Trustee nor any Covered
Individual shall have any right to compel such additional deposits.

         (f)      Upon a Change in Control, Company shall, as soon as possible,
but in no event longer than 90 days following the Change in Control, as defined
herein, make an irrevocable contribution to the Trust in an amount that is
sufficient to provide each Covered Individual with the health coverage to which
he or she would be entitled pursuant to the terms of the Agreements and this
Trust Agreement ("Health Coverage") as of the date on which the Change in
Control occurred. Company shall promptly provide written notice of a Change in
Control to the Trustee.

         An amount is "sufficient," within the meaning of the preceding sentence
if, when added to any cash or other property previously contributed to the Trust
by the Company, the fair market value of the Trust assets as of the date the
contribution is made equals or exceeds the sum of (1) the actuarial present
value of the future premium and "out-of-pocket expense" cost of the Health
Coverage, and future compensation and expenses of the Trustee, as of the date
the Change in Control occurred, and (2) the unpaid current premium and
"out-of-pocket expense" cost of such coverage, and all compensation owed and
expenses incurred but unpaid of the Trustee, pursuant to Section 9, as of such
date. All calculations and determinations required under this paragraph shall be
made by an independent actuary or accountant selected by the Trustee.

                                    SECTION 2
              PAYMENT TO OR FOR THE BENEFIT OF COVERED INDIVIDUALS

         (a)      Company shall deliver to Trustee a schedule (the "Payment
Schedule"), from time to time, that indicates the amounts payable for Health
Coverage in respect of each Covered Individual, or that provides a formula or
other instructions acceptable to Trustee for determining the amounts so payable,
the payee, and the time for payment of such amounts. Such amounts shall include
payment for the following types of health insurance: medical, dental and vision
care for each Covered Individual, and long-term care for the Executive and his
spouse. Except as otherwise provided

                                       2
<PAGE>

herein, Trustee shall make payments to one or more health insurance carriers in
accordance with such Payment Schedule.

          Unless payment is made by the Company pursuant to Section 2(c) below,
the Trustee shall reimburse each Covered Individual for any out-of-pocket
expense, as defined herein, of the Covered Individual. For purposes of this
Trust Agreement, an "out-of-pocket expense" is a deductible, co-payment or
coinsurance amount required to be paid by a Covered Individual under the benefit
design of the Health Coverage; and any premium paid by a Covered Individual for
any Medicare coverage, including Part B hospital coverage, Part D prescription
drug coverage, and supplemental (Medigap) coverage, shall be deemed an
out-of-pocket expense that is reimbursable in accordance with the procedures
described in this Section 2(a). Expenses which are not insured due to
limitations or exclusions under the benefit design of the Health Coverage or
under Medicare and Medigap coverage, whichever is applicable, shall not be an
"out-of-pocket expense" under the Trust. On or before March 11, 2005, the
Trustee shall transfer, on behalf of each Executive, to Benefit Concepts (or
such other agent or vendor designated by the Company) the amount of Five
Thousand Dollars ($5,000) to fund a separate account for the payments to be made
under this paragraph. Thereafter, the Trustee shall on a quarterly basis make
transfers to such accounts based on actual experience as reported to the Trustee
by the Company or its designated agent. The Company or its designated agent
shall provide the Trustee with instructions regarding the reporting and
withholding of any federal, state, or local taxes that may be required to be
withheld by the Trustee with respect to the payment of benefits pursuant to the
terms of the Agreements and this Trust Agreement, and the Trustee shall report
and pay such amounts to the appropriate taxing authorities as instructed by the
Company or its designated agent.

         (b)      The entitlement of any person to Health Coverage under the
Agreements shall be determined by Company or such party as it shall designate,
but any claim for benefits shall be considered and reviewed by the insurance
carrier or claims administrator under the procedures set out in the applicable
insurance policy or other applicable coverage document. The Company shall
appoint a third party administrator to receive and process claims from Covered
Individuals, to the extent such claims are not processed by the insurance
carrier. The Trustee shall be entitled to rely on such determinations made by
the Company, the insurance carrier, or claims administrator.

         (c)      Company may make the payments to a health insurance carrier
described in Section 2(a) directly to such carrier, or the payments to reimburse
for out-of-pocket expenses (described in such section) directly to a Covered
Individual, as they become due under the terms of the Agreements or this Trust
Agreement. Company shall notify Trustee of its decision to make such payments
directly prior to the time amounts are payable under Section 2(a). In addition,
if the principal of the Trust, and any earnings thereon, are not sufficient to
make payments in accordance with the terms of the Agreements and this Trust
Agreement, Company shall make the balance of each such payment as it falls due.
Trustee shall notify Company where principal and earnings are not sufficient.

         (d)      The Trustee shall purchase individual policies to secure the
medical insurance component of Health Coverage for Covered Individuals upon the
first to occur of the following events:

                                       3
<PAGE>

                  (1)      the Company ceases to maintain a comprehensive group
         health plan covering major medical expenses for the Covered
         Individuals, or

                  (2)      the favorable tax treatment of health coverage or
         health benefits under the Internal Revenue Code ceases to be available
         to Covered Individuals under the Company group health plan covering
         them, or

                  (3)      the Company directs the Trustee to purchase an
         individual policy.

The Trustee shall not be obligated to purchase individual policies to secure the
medical insurance component of Health Coverage for Covered Individuals before it
has received written notice of an event described in (d)(1) or (d)(2) above from
the Company or a Covered Individual. The Trustee may engage or consult with an
independent broker to assist it in purchasing individual policies, and may rely
on the advice of such broker. If the principal of the Trust, and any earnings
thereon, are not sufficient to purchase the individual policies required to be
purchased under this Section 2(d), Company shall provide the additional amounts
necessary to make such purchase. Trustee shall notify the Company if principal
and earnings are not sufficient. Notwithstanding Section 2(d)(2) to the
contrary, Trustee shall not purchase individual policies if notified by the
Company that it will, through additional (estimated) payments to Covered
Individuals, put them in substantially the same place they would have been in
had the favorable tax treatment remained available.

         (e)      If the Company does not deliver a Payment Schedule or provide
a formula or other instructions providing for payment of Health Coverage
pursuant to Section 2(a), the Trustee shall be authorized to provide for such
payment. The Trustee shall pay the entire premium due for Health Coverage,
except to the extent the Company makes such payment as provided in Section 2(c).

                                    SECTION 3
                  TRUSTEE RESPONSIBILITY REGARDING PAYMENTS TO
                   TRUST BENEFICIARY WHEN COMPANY IS INSOLVENT

         (a)      Trustee shall cease payments to or for the benefit of Covered
Individuals if Company is Insolvent. Company shall be considered "Insolvent" for
purposes of this Trust Agreement if (i) Company is unable to pay its debts as
they become due, or (ii) Company is subject to a pending proceeding as a debtor
under the United States Bankruptcy Code.

         (b)      At all times during the continuance of this Trust, as provided
in Section 1(d) hereof, the principal and income of the Trust shall be subject
to claims of general creditors of Company under federal and state law as set
forth below.

                  (1)      The Board of Directors and the Chief Executive
         Officer of Company shall have the duty to inform Trustee in writing of
         Company's Insolvency. If a person claiming to be a creditor of Company
         alleges in writing to Trustee that Company has become Insolvent,

                                       4
<PAGE>
         Trustee shall determine whether Company is Insolvent and, pending such
         determination, Trustee shall discontinue payments to or for the benefit
         of Covered Individuals.

                  (2)      Unless Trustee has actual knowledge of Company's
         Insolvency, or has received notice from Company or a person claiming to
         be a creditor alleging that Company is Insolvent, Trustee shall have no
         duty to inquire whether Company is Insolvent. Trustee may in all events
         rely on such evidence concerning Company's solvency as may be furnished
         to Trustee and that provides Trustee with a reasonable basis for making
         a determination concerning Company's solvency.

                  (3)      If at any time Trustee has determined that Company is
         Insolvent, Trustee shall discontinue payments to or for the benefit of
         Covered Individuals and shall hold the assets of the Trust for the
         benefit of Company's general creditors. Nothing in this Trust Agreement
         shall in any way diminish any rights of Covered Individuals to pursue
         their rights as general creditors of Company with respect to benefits
         due under the Agreements, the Trust Agreement or otherwise.

                  (4)      Trustee shall resume the payment of benefits to or
         for the benefit of Covered Individuals in accordance with Section 2 of
         this Trust Agreement only after Trustee has determined that Company is
         not Insolvent (or is no longer Insolvent).

         (c)      Provided that there are sufficient assets, if Trustee
discontinues payments from the Trust pursuant to Section 3(b) hereof and
subsequently resumes such payments, the first payment following such
discontinuance shall include the aggregate amount of all payments otherwise due
hereunder for Health Coverage for the period of such discontinuance, less the
aggregate amount of any such payments for Health Coverage made by Company in
lieu of the payments provided for hereunder during any such period of
discontinuance.

                                    SECTION 4
                               PAYMENTS TO COMPANY

         Except as provided in Section 3 hereof, Company shall have no right or
power to direct Trustee to return to Company or to divert to others any of the
Trust assets before all payments to or for the benefit of Covered Individuals
have been made pursuant to the terms of the Agreements and this Trust Agreement.

                                    SECTION 5
                              INVESTMENT AUTHORITY

         (a)      In no event may Trustee invest in securities (including stock
or rights to acquire stock) or obligations issued by Company, other than a de
minimis amount held in common investment vehicles in which Trustee invests. All
rights associated with assets of the Trust shall be

                                       5
<PAGE>

exercised by Trustee or the person designated by Trustee, and shall in no event
be exercisable by or rest with Covered Individuals.

         (b)      Trustee shall invest and reinvest the principal and income of
the Trust and keep the Trust invested, without distinction between principal and
income, in such investments as Trustee in its sole discretion shall determine
consistent with such written investment guidelines as the Company's chief
financial officer may from time to time provide. The Trustee may rely on such
written guidelines and, except as otherwise provided by law, shall have no
liability for following such guidelines. In the event Company fails to provide
written investment guidelines, Trustee shall invest the Trust in one or more of
the following instruments, as Trustee in its sole discretion shall determine:
U.S. Treasury bills, notes or bonds; U.S. Government agency securities; time
deposits; certificates of deposit (issued by financial institutions rated A or B
by Keefe, Bruyette & Woods or similar rating agency); commercial paper (rated
A-1 by Standard & Poors or P-1 or better by Moody's Investor Service); bankers'
acceptances; repurchase agreements; and pooled short-term investment funds. In
addition, Trustee may invest or reinvest all or any specified portion of the
Trust in any common, collective or commingled trust fund which has been or may
hereafter be established and maintained by Trustee. Notwithstanding the
foregoing provisions of this paragraph (b) to the contrary, Trustee shall, from
time to time, liquidate Trust investments to the extent necessary to make a
payment required under this Trust Agreement.

                                    SECTION 6
                              DISPOSITION OF INCOME

         During the term of this Trust, all income received by the Trust, net of
expenses and taxes, shall be accumulated and reinvested.

                                    SECTION 7
                              ACCOUNTING BY TRUSTEE

         (a)      Trustee shall keep or cause to be kept accurate and detailed
accounts of any receipts, investments, disbursements and other transactions
hereunder and all necessary and appropriate records required to identify
correctly and reflect accurately the condition of the Trust. All such accounts
and records shall be open to inspection and audit at all reasonable times by any
person, including an independent public accountant, designated by Company, and
shall be preserved (in original form or on microfilm, magnetic tape or any other
similar process) for such period as Trustee may determine. Trustee may destroy
such accounts and records only after notifying Company in writing of its
intention to do so and transferring to Company any of such documents requested
in writing by Company. The Trustee shall not be obligated to maintain duplicate
copies of receipts for reimbursements (or other records) maintained by the
Company or its designated agents.

         (b)      Within 30 days after the close of each calendar year, and
within 30 days after the removal or resignation of Trustee or the termination of
the Trust, Trustee shall file with Company a written account setting forth all
investments, receipts, disbursements, and other transactions effected

                                       6
<PAGE>

by it during the preceding calendar year, or during the period from the close of
the preceding calendar year to the date of such removal, resignation, or
termination. Such account shall include a description of all investments and
securities purchased and sold with the cost of such purchase or net proceeds of
such sales and showing all cash, securities, and other property held at the end
of such calendar year or other period.

         (c)      Nothing contained in this Trust Agreement shall be construed
as depriving Trustee, Company, or Covered Individuals of the right to have a
judicial settlement of Trustee's accounts. Upon any proceeding for a judicial
settlement of Trustee's accounts or for instructions, the only necessary parties
thereto, in addition to Trustee, shall be Company and Covered Individuals.

         (d)      In addition to any returns required of Trustee by law, Trustee
shall prepare and file such tax returns and other reports as Company and Trustee
may from time to time agree in writing are necessary or advisable.

                                    SECTION 8
                            RESPONSIBILITY OF TRUSTEE

         (a)      Trustee shall act with the care, skill, prudence and diligence
under the circumstances then prevailing that a prudent person acting in like
capacity and familiar with such matters would use in the conduct of an
enterprise of like character and with like aims, provided, however, that Trustee
shall incur no liability to any person for any action taken pursuant to a
direction, request or approval given by Company which is contemplated by, and in
conformity with, the terms of the Agreements or this Trust and is given in
writing by Company, or upon the advice of legal counsel, accountants, actuaries
or other suitable agents reasonably retained by the Trustee in accordance with
Section 8(c). In the event of a dispute between Company and a party, Trustee may
apply to a court of competent jurisdiction to resolve the dispute.

         (b)      Trustee may commence or defend suits or legal proceedings,
represent the Trust in all actions and settle, compromise, or submit to
arbitration any disputes involving the Trust. The Company, on its own behalf and
on behalf of its parent organization, subsidiaries, successors and assigns,
hereby jointly and severally agrees to and hereby does indemnify, defend and
hold harmless the Trustee, and its successors, assigns, officers, directors,
employees, agents and attorneys from and against any and all costs, liabilities
and expenses (including, without limitation, reasonable attorneys' fees and
expenses and costs of enforcing this provision) arising out of or in any way
connected with the Trustee's service under this Agreement, except for any cost,
liability or expense arising out of the Trustee's own negligent act or omission,
willful misconduct or fraud. In the event of such negligent act or omission,
willful misconduct or fraud, Trustee agrees to and hereby does indemnify, defend
and hold harmless the Company, and its successors, assigns, officers, directors,
employees, agents and attorneys from and against any and all costs, liabilities
and expenses (including, without limitation, reasonable attorneys' fees and
expenses and costs of enforcing this provision) relating to such negligent act
or omission, willful misconduct or fraud by Trustee and agrees to be primarily
liable for such payments. If Company does not pay Trustee's costs, liabilities
and expenses in a reasonably timely manner, Trustee is specifically authorized
to obtain such payment from Trust assets.

                                       7

<PAGE>

         (c)      Trustee may engage or consult with legal counsel, accountants,
enrolled actuaries, or any other suitable agents to assist it in performing any
of its duties or obligations hereunder; rely upon the advice of such counsel,
accountants, actuaries, or agents; and pay the reasonable fees, expenses, and
compensation of such counsel, accountants, actuaries, or agents from the Trust
to the extent that they are not paid by Company.

         (d)      Trustee shall have, without exclusion, all powers conferred on
Trustees by applicable law, unless expressly provided otherwise herein,
provided, however, that if an insurance policy is held as an asset of the Trust,
Trustee shall have no power to name a beneficiary of the policy other than the
Trust, to assign the policy (as distinct from conversion of the policy to a
different form) other than to a successor Trustee, or to loan to any person the
proceeds of any borrowing against such policy.

         (e)      Notwithstanding any powers granted to Trustee pursuant to this
Trust Agreement or to applicable law, Trustee shall not have any power that
could give this Trust the objective of carrying on a business and dividing the
gains therefrom, within the meaning of section 301.7701-2 of the Procedure and
Administrative Regulations promulgated pursuant to the Internal Revenue Code.

                                    SECTION 9
                      COMPENSATION AND EXPENSES OF TRUSTEE

         (a)      Company shall pay Trustee such reasonable compensation for its
services hereunder as may be agreed upon in writing from time to time by Company
and Trustee. Company shall also pay the reasonable expenses incurred by Trustee
in the performance of its duties under this Trust Agreement. Such compensation
and expenses shall be paid from the Trust to the extent that they are not paid
by Company.

         (b)      Company shall pay any taxes which are lawfully levied or
assessed upon or become payable with respect to the Trust. To the extent that
any taxes lawfully levied or assessed upon the Trust are not paid by Company,
Trustee shall pay such taxes out of the Trust. Trustee shall contest the
validity of taxes in any manner deemed appropriate by Company, but at Company's
expense. In the alternative, Company itself may contest the validity of any such
taxes.

                                   SECTION 10
                       RESIGNATION AND REMOVAL OF TRUSTEE

         (a)      Trustee may resign at any time by written notice to Company,
which shall be effective 60 days after receipt of such notice unless Company and
Trustee agree otherwise.

         (b)      Trustee may be removed by Company with or without cause at any
time upon at least 60 days' notice in writing to Trustee, or upon shorter notice
accepted by Trustee. In the event of

                                       8

<PAGE>

such removal, or a resignation in accordance with Section 10(a) hereof, Trustee
shall duly file with Company a written account as provided in Section 7(b)
hereof.

         (c)      Upon resignation or removal of Trustee and appointment of a
successor Trustee, all assets shall subsequently be transferred to the successor
Trustee. The transfer shall be completed within 60 days after receipt of notice
of resignation, removal, or transfer, unless Company extends the time limit.

         (d)      If Trustee resigns or is removed, a successor shall be
appointed, in accordance with Section 11 hereof, by the effective date of
resignation or removal under paragraphs (a) or (b) of this Section. If no such
appointment has been made, Trustee may apply to a court of competent
jurisdiction for appointment of a successor or for instructions. All expenses of
Trustee in connection with the proceeding shall be allowed as administrative
expenses of the Trust.

                                   SECTION 11
                            APPOINTMENT OF SUCCESSOR

         (a)      Within 60 days after the date of a notice of resignation or
removal of Trustee, in accordance with Section 10(a) or (b) hereof, Company
shall designate any third party, such as a bank trust department or other party
that may be granted corporate trust powers under state law, as a successor to
replace Trustee upon resignation or removal. The appointment shall be effective
when accepted in writing by the new Trustee, who shall have all of the rights
and powers of the former Trustee, including ownership rights in the Trust
assets. The former Trustee shall execute any instrument necessary or reasonably
requested by Company of the successor Trustee to evidence the transfer. The word
"Trustee" wherever used herein, except where the context otherwise requires,
shall be deemed to include any successor Trustee. If the Company fails to
designate a successor Trustee within ninety (90) days of the date of a notice of
resignation, the Trustee is authorized to designate as the successor an
institutional trustee with offices in Maine.

         (b)      The successor Trustee need not examine the records and acts of
any prior Trustee and may retain or dispose of existing Trust assets, subject to
Sections 7 and 8 hereof. The successor Trustee shall not be responsible for and
Company shall indemnify and defend the successor Trustee from any claim or
liability resulting from any action or inaction of any prior Trustee or from any
other past event, or any condition existing at the time it becomes successor
Trustee.

         (c)      The Company shall require any successor (whether direct or
indirect and whether by purchase, lease, merger, consolidation, liquidation or
otherwise) to all or substantially all of the Company's business and/or assets,
by an agreement in substance and form satisfactory to the Trustee, to assume
this Trust and to agree expressly to perform this Trust in the same manner and
to the same extent as the Company would be required to perform it in the absence
of a succession. The Company's failure to obtain such agreement prior to the
effectiveness of a succession shall be a breach of this Trust and shall entitle
the Trustee to purchase individual policies to secure the medical insurance
component of Health Coverage for Covered Individuals. For all purposes under

Zafiris G. Zafirellis
President and Chief Executive Officer
Biopure Corporation
11 Hurley Street
Cambridge, MA  02141

Dear Zaf:

This letter represents our understanding of the basis upon which C.E. Unterberg,
Towbin LLC, a Delaware limited liability company ("CEUT"), is engaged to provide
financial advisory and investment banking services to Biopure Corporation (the
"Company"). This letter solely relates to such financial advisory and investment
banking services and not to any potential investment in the Company by CEUT or
any of its affiliates.

1.    The Company hereby retains CEUT to act as its exclusive financial advisor
      with respect to a best efforts public offering intended to raise up to
      $18.5 million (including the exercise price of warrants) through sales of
      the Company's common stock and warrants to acquire additional shares of
      the Company's common stock (the "Securities") in a take-down from the
      Company's shelf registration statement. The Company will not offer any of
      the Securities for sale to, or solicit any offers to buy from, any person
      or persons, whether directly or indirectly, otherwise than through CEUT;
      provided, however, that under no circumstances shall CEUT be liable for
      failure to obtain or produce the proposed financing.

2.    As part of our engagement, CEUT will provide the Company with the
      following services:

      a.    Review the Company's current business plan and financial needs, and
            assist in the preparation of a preliminary and final prospectus
            supplement for distribution to prospective investors;

      b.    Identify and contact potential institutional and/or strategic
            investors and assist the Company in conducting a "road show" with
            respect to the public offering;

      c.    As appropriate, with management of the Company, meet with potential
            investors and discuss with them the Company's business; and

      d.    Assist the Company and the Company's legal counsel in preparing
            documents related to the transaction and having such documents
            executed in order to close the transaction and any other agreements
            as may be necessary.

3.    As compensation for the services rendered by CEUT hereunder, the Company
      agrees to pay CEUT at closing for the sale of Securities, a cash fee equal
      to 6.5% of the gross proceeds from the sale of the Securities, together
      with common stock warrants (the "Warrants") equal to 3.0% of the number of
      common shares sold in the transaction. The Warrants will expire on the
      fifth anniversary from closing.

4.    In addition to the fee specified in Section 3 above, the Company shall
      reimburse CEUT for its reasonable expenses including fees and
      disbursements of counsel incurred by CEUT in connection with its
      engagement hereunder.

5.    CEUT and the Company have entered into a separate letter agreement, dated
      the date hereof, providing for the indemnification of CEUT by the Company
      in connection with CEUT's engagement hereunder, the terms of which are
      incorporated into this agreement in their entirety.

6.    For a period of 6 months from the date hereof, the Company grants to CEUT
      the right to provide investment banking services to the Company on an
      exclusive basis in all matters for which investment banking services are
      sought by the Company (the "Right of First Refusal"). For the purposes
      hereof, investment banking services shall consist of (i) acting as lead
      manager for any underwritten public offering of securities of the Company;
      (ii) acting as placement agent or financial advisor in connection with any
      private offering of securities of the Company; and, (iii) acting as
      financial advisor in connection with any sale or other transfer by the
      Company, directly or indirectly, of a majority or controlling portion of
      its capital stock or assets to another entity, any purchase or other
      transfer by another entity, directly or indirectly, of a majority or
      controlling portion of the capital stock or assets of the Company, and any
      merger or consolidation of the Company with another entity, but not
      including strategic alliance transactions. CEUT shall notify the Company
      of its intention to exercise the Right of First Refusal within 10 business
      days following notice in writing by the Company to CEUT of any transaction
      specified in (i)-(iii) above. If CEUT declines to serve as investment
      banker to the Company pursuant to the Right of First Refusal, the Company
      shall have the right to retain any other person or persons to provide such
      services on terms and conditions that are not materially more favorable to
      such other person or persons than the terms declined by CEUT.
      Additionally, during the same 6 month time period, the Company shall pay
      CEUT fees as outlined in paragraph 3 above for any subsequent financing
      with the same investors, introduced to the Company for the first time by
      CEUT, that participate in a transaction contemplated by Section 1 above.

7.    The Company recognizes and confirms that CEUT in acting pursuant to this
      engagement will be using publicly available information and information in
      reports and other materials provided by others, including, without
      limitation, information provided by or on behalf of the Company and that
      CEUT does not assume responsibility for and may rely, without independent
      verification, on the accuracy and completeness of any such information.
      The Company agrees to furnish or cause to be furnished to CEUT all
      necessary or appropriate information for use in its engagement and hereby
      warrants that any information relating to the Company, that is furnished
      to CEUT by or on behalf of the Company, will be true and correct in all
      material respects and not misleading in any material respect.

8.    The term of this engagement shall extend until six (6) months from the
      date of this agreement, unless terminated in writing by either party with
      seven (7) days prior notice. Any such termination shall not (except as
      provided herein) affect the compensation, reimbursement, right of first
      refusal or indemnification provisions set forth herein, all of which shall
      remain in full force and effect. In addition, the Company shall be
      responsible for any fees as outlined above for any financing transaction
      undertaken by the Company in lieu of the contemplated transaction
      described herein with any investors contacted by

      CEUT that is concluded within six (6) months of the date of termination of
      this agreement.

9.    Notwithstanding its engagement hereunder, CEUT may not, without its prior
      written consent, be quoted or referred to in any document, release or
      communication prepared, issued or transmitted by the Company (including
      any entity controlled by, or under common control with, the Company and
      any director, officer, employee or agent thereof).

10.   Following completion of this engagement, CEUT shall have the right to
      place advertisements in financial and other newspapers and journals at its
      own expense describing its services to the Company hereunder.

11.   This Agreement shall be governed by, and construed and enforced in
      accordance with, the laws of the State of New York, without regard to such
      state's rules concerning conflicts of law, and will be binding upon and
      inure to the benefit of the Company and CEUT and their respective
      successors and assigns. Each of the parties hereto also hereby submits to
      the jurisdiction of the federal courts located in the Southern District of
      New York or in any New York State court located in New York County in any
      proceeding arising out of or relating to this Agreement, agrees not to
      commence any suit, action or proceeding relating hereto except in such
      courts, and waives, to the fullest extent permitted by law, the right to
      move to dismiss or transfer any action brought in such court on the basis
      of any objection to personal jurisdiction, venue or inconvenient forum.
      Solely, for purposes of enforcing this Agreement, the Company hereby
      consents to personal jurisdiction, service of process and venue in any
      court in which any claim or proceeding that is subject to this Agreement
      is brought against CEUT. THE COMPANY AND CEUT AGREE TO WAIVE TRIAL BY JURY
      IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY OR ON BEHALF OF
      EITHER PARTY WITH RESPECT TO ANY MATTER WHATSOEVER RELATING TO OR ARISING
      OUT OF ANY ACTUAL OR PROPOSED TRANSACTION OR THE ENGAGEMENT OF OR
      PERFORMANCE BY CEUT HEREUNDER.

12.   This agreement may be executed in counterparts, each of which shall be
      deemed to be an original, but which together shall constitute one and the
      same agreement.

CEUT will act under this Agreement as an independent contractor with obligations
solely to the Company.

The Company acknowledges that CEUT and its affiliates may have and may in the
future have investment banking and other relationships with parties other than
the Company, which parties may have interests with respect to the proposed
public offering. Although CEUT in the course of such other relationships may
acquire information about the proposed public offering, potential purchasers of
the Securities or such other parties, CEUT shall have no obligation to disclose
such information to the Company or to use such information on behalf of the
Company. Furthermore, the Company acknowledges that CEUT may have fiduciary or
other relationships whereby CEUT may exercise voting power over securities of
various persons, which securities may from time to time include securities of
the Company or of potential purchasers of the Securities or others with
interests in respect of the potential public offering. The Company acknowledges
that CEUT may exercise such powers and otherwise perform its functions in
connection with such fiduciary or other relationships without regard to its
relationship to the Company hereunder.

C.E. Unterberg, Towbin
350 Madison Avenue
New York, NY 10017

Ladies and Gentlemen:

In connection with the engagement (the "Engagement") of C.E. Unterberg, Towbin
LLC, a Delaware limited liability company ("CEUT") to advise and assist Biopure
Corporation (the "Company") in connection with the matters contemplated by
Section 1 of the letter agreement (a "Transaction") dated the date hereof
between CEUT and the Company (the "Letter Agreement"), the Company agrees that
it will indemnify and hold harmless CEUT and its affiliates and their respective
directors, officers, agents, representatives and employees (collectively,
"Representatives") and each other person controlling CEUT or any of CEUT's
affiliates (collectively, the "Indemnified Parties"), to the fullest extent
permitted by law, from and against any and all losses, expenses, claims,
liabilities or proceedings including, but not limited to, reasonable legal fees
and expenses and the costs of enforcing any of the terms hereof (collectively,
"Losses") (i) related to or arising out of (A) oral or written information
provided by the Company and/or its Representatives in connection with a
Transaction, or (B) any other action or failure to act by (1) the Company and/or
its Representatives or (2) by CEUT or any Indemnified Party at the Company's
request or with the Company's consent, or (ii) otherwise related to or arising
out of the Engagement or any Transaction or conduct in connection therewith;
provided that the Company shall have no indemnification obligation hereunder
with respect to Losses arising from the gross negligence or willful misconduct
of any Indemnified Party.

In the event that the foregoing indemnity is unavailable to any Indemnified
Party for any reason, then the Company agrees to contribute to any Losses
related to or arising out of the engagement or any transaction or conduct in
connection therewith as follows. With respect to Losses referred to in clause
(i) of the preceding paragraph, each of the Company and CEUT shall contribute in
such proportion as is appropriate to reflect the relative benefits received by
CEUT, on the one hand, and by the Company, on the other hand, from a
Transaction. With respect to any other Losses, and for Losses referred to in
clause (i) of the preceding paragraph if the allocation provided by the
immediately preceding sentence is unavailable for any reason, each of the
Company and CEUT shall contribute in such proportion as is appropriate to
reflect not only the relative benefits, but also the relative fault of each of
the Company and CEUT in connection with the alleged misstatements, omissions and
actions and other relevant equitable considerations. Benefits received by the
Company in connection with a Transaction shall be deemed to be equal to the
gross cash consideration received by the Company from the sale of securities in
such Transaction, and the benefits received by CEUT shall be deemed to be equal
to the compensation paid to CEUT by the Company in connection with the
Engagement (exclusive of amounts paid for reimbursement of expenses or paid
under this agreement). Relative fault shall be determined by reference to, among
other things, whether any alleged untrue statement or omission relates to
information provided by, or any alleged conduct is engaged in by, the Company
and/or its Representatives, on the one hand, or CEUT, on the other hand. CEUT
and the Company agree that it would not be just and equitable if contribution
were determined by pro rata allocation or by any other method of allocation that
does not take account of the equitable considerations referred to above.
Notwithstanding anything to the contrary above, in no event shall CEUT be
responsible for any amounts in excess of the amount of the compensation actually
paid by the Company to CEUT in connection with the Engagement (exclusive of
amounts paid for reimbursement of expenses or paid under this agreement). No
person or entity guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act of 1933, as

<PAGE>

amended) shall be entitled to contribution from any person or entity who was not
guilty of such fraudulent misrepresentation.

Promptly after CEUT receives notice of the commencement of any action or other
proceeding in respect of which indemnification or reimbursement may be sought
hereunder, CEUT will notify the Company thereof; but the omission so to notify
the Company shall not relieve the Company from any obligation hereunder. If any
such action or other proceeding shall be brought against any Indemnified Party,
the Company shall, upon written notice given reasonably promptly following
notice to the Company by such Indemnified Party of such action or proceeding, be
entitled to assume the defense thereof at its expense with counsel chosen by the
Company and reasonably satisfactory to such Indemnified Party; provided,
however, that any Indemnified Party may at its own expense retain separate
counsel to participate in such defense. Notwithstanding the foregoing, such
Indemnified Party shall have the right to employ separate counsel at the
Company's expense and to control its own defense of such action or proceeding
if, in the reasonable opinion of counsel to such Indemnified Party, (i) there
are or may be legal defenses available to such Indemnified Party or to other
Indemnified Parties that are different from or additional to those available to
the Company or (ii) a conflict or potential conflict exists between the Company
and such Indemnified Party that would make such separate representation
advisable. The Company agrees that it will not, without the prior written
consent of CEUT, which consent shall not be unreasonably withheld or delayed,
settle or compromise or consent to the entry of any judgment in any pending or
threatened claim, action or proceeding relating to the matters contemplated by
the Engagement or any Transaction (whether or not any Indemnified Party is a
party thereto) unless such settlement, compromise or consent includes an
unconditional release of CEUT and each other Indemnified Party from all
liability arising or that may arise out of such claim, action or proceeding.

The Company further agrees that no Indemnified Party shall have any liability
(whether direct or indirect, in contract or tort or otherwise) to the Company or
any of its affiliates, Representatives, creditors or security holders for or in
connection with the Engagement or any Transaction, except in the case of the
gross negligence or willful misconduct of any Indemnified Party.

The foregoing agreement is in addition to any rights CEUT may have at common law
or otherwise and shall be binding on and inure to the benefit of any successors,
assigns, and personal representatives of the Company and each Indemnified Party.
This agreement shall be governed by, and construed and enforced in accordance
with, the laws of the State of New York, without regard to such state's rules
concerning conflicts of laws. Each of the parties hereto also hereby submits to
the jurisdiction of the federal courts located in the Southern District of New
York or in any New York State court located in New York County in any proceeding
arising out of or relating to this agreement, including federal district courts
located in such state, agrees not to commence any suit, action or proceeding
relating hereto except in such courts, and waives, to the fullest extent
permitted by law, the right to move to dismiss or transfer any action brought in
such court on the basis of any objection to personal jurisdiction, venue or
inconvenient forum. Solely, for purposes of enforcing this agreement, the
Company hereby consents to personal jurisdiction, service of process and venue
in any court in which any claim or proceeding that is subject to this agreement
is brought against CEUT. ANY RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY CLAIM OR
PROCEEDING RELATED TO OR ARISING OUT OF THE ENGAGEMENT, OR ANY TRANSACTION OR
CONDUCT IN CONNECTION THEREWITH OR THIS AGREEMENT IS WAIVED.

This agreement shall remain in full force and effect notwithstanding the
completion or termination of the engagement.

                                 Very truly yours,

Dear Zaf:

This letter amends the letter dated August 4, 2004 (the "Engagement Letter")
between the parties hereto. Terms defined in the Engagement Letter and not
otherwise defined herein are used herein with the meaning so defined. Effective
as of the date hereof, the Engagement Letter is hereby amended as follows:

Section 6 of the Engagement Letter is amended and restated to read in its
entirety as follows:

      6.    For a period of 6 months from the date hereof, the Company grants to
            CEUT the right to provide investment banking services to the Company
            on an exclusive basis in all matters for which investment banking
            services are sought by the Company (the "Right of First Refusal").
            For the purposes hereof, investment banking services shall consist
            of (i) acting as lead manager for any underwritten public offering
            of securities of the Company; (ii) acting as placement agent or
            financial advisor in connection with any private offering of
            securities of the Company; and, (iii) acting as financial advisor in
            connection with any sale or other transfer by the Company, directly
            or indirectly, of a majority or controlling portion of its capital
            stock or assets to another entity, any purchase or other transfer by
            another entity, directly or indirectly, of a majority or controlling
            portion of the capital stock or assets of the Company, and any
            merger or consolidation of the Company with another entity, but not
            including strategic alliance transactions. CEUT shall notify the
