TAX EXEMPTION AGREEMENT

     The undersigned are, respectively, duly qualified and acting officers of
the City of Chaska, Minnesota (the “Issuer”), Lifecore Biomedical, Inc. (the
“Borrower”), and Wells Fargo Bank, National Association, as trustee ( the
“Trustee”). The City Administrator of the Issuer is charged, with others, with
the responsibility for delivering the $5,630,000 City of Chaska, Minnesota
Variable Rate Demand Purchase Revenue Bonds (Lifecore Biomedical, Inc. Project),
Series 2004 (the “Bonds”) on August 19, 2004 (the “Closing Date”). The Bonds
were authorized pursuant to the Issuer’s resolution adopted July 19, 2004. The
Bonds are being issued pursuant to an Indenture of Trust dated as of August 1,
2004 (the “Indenture”) between the Issuer and the Trustee. The Bonds were sold
pursuant to a Bond Purchase Agreement (the “Purchase Agreement”) dated
August 19, 2004, by and between the Issuer, the Borrower, and Northland
Securities, Inc. (the “Underwriter”). Pursuant to Section 1.150(f)(1)(i) of the
Regulations, the Bonds are deemed to have been sold on the Closing Date. Certain
terms are defined in Article VII hereof. Terms used herein and not defined
herein shall have the meanings given to them in the Indenture.

     One purpose of executing this Agreement is to set forth various facts
regarding the Bonds and to establish the expectations of the Issuer, the
Borrower, and the Trustee as to future events regarding the Bonds and the use of
Bond proceeds. To the extent such facts do not relate directly to the Issuer or
the Trustee, the Issuer and the Trustee are relying upon the certifications of
the Borrower and other parties, which is deemed by the undersigned to be
reasonable and prudent. The certifications and representations made herein and
the expectations presented herein are intended, and may be relied upon, as a
certification of an officer of the Issuer given in good faith as described in
Section 1.148-2(b)(2) of the Regulations.

     The certifications, covenants and agreements contained herein are made on
behalf of the Issuer, the Borrower, and the Trustee for the benefit of the
owners from time to time of the Bonds. We do hereby certify, covenant and agree
on behalf of the Issuer, the Borrower, and the Trustee, respectively, the
following:

 

--------------------------------------------------------------------------------

 

ARTICLE I

DESCRIPTION OF THE PURPOSE OF THE BONDS

     Section 1.1 Purpose of the Bonds. The Bonds are being issued to provide
refinancing for an existing manufacturing facility of the Borrower located in
the City (the “Project”), through the refunding in full of the outstanding
Industrial Development Revenue Bonds (Lifecore Biomedical, Inc. Project),
Series 1990, issued by the Issuer in the original aggregate principal amount of
$7,000,000 (the Refunded Bonds”). A breakdown of sources and uses of funds
appears in Section 2.1 hereof.

     The proceeds from the sale of the Bonds will be loaned by the Issuer to the
Borrower pursuant to a Loan Agreement dated as of August 1, 2004 (the “Loan
Agreement”) between the Issuer and the Borrower. The proceeds of the Bonds will
be deposited with the Trustee into the Project Fund and applied to the refunding
of the Refunded Bonds, provided, however, that any proceeds representing accrued
interest on the Bonds shall be deposited in the Bond Fund.

     In connection with the issuance of the Bonds, M&I Marshall Ilsley Bank (the
“Bank”) has issued its Irrevocable Letter of Credit (the “Letter of Credit”)
pursuant to a Reimbursement Agreement dated as of August 1, 2004 (the
“Reimbursement Agreement”) between the Bank and the Borrower to support payment
of the principal of and interest on the Bonds and to pay the purchase price of
Bonds tendered for purchase (sometimes referred to as “Tendered Bonds”), in
accordance with the Indenture.

     Section 1.2 Redemption in Whole of Refunded Bonds. The Borrower has caused
the Refunded Bonds to be called for redemption in whole on September 1, 2004
(the “Call Date”), in accordance with the provisions of the Prior Indenture. The
Call Date will be less than 90 days from the date of issuance of the Bonds. The
original principal amount of the Series 2004 Bonds is in an amount not greater
than the current outstanding principal amount of the Refunded Bonds. The
principal amount of the Series 2004 Bonds is not larger than the amount
necessary to cause the Refunded Bonds to be redeemed in whole, in accordance
with the provisions of the Prior Indenture and in accordance with the provisions
hereof. The entire gross proceeds of the Series 2004 Bonds ($5,630,000) are to
be expended solely for the payment and discharge on the Call Date of the
outstanding principal amount of the Refunded Bonds. The weighted average
maturity of the Series 2004 Bonds does not exceed the remaining weighted average
maturity of the Refunded Bonds.

     Section 1.3 Reimbursement. Except for certain preliminary expenditures
evidenced by the files and records of the Borrower (the “Preliminary
Expenditures”), none of the proceeds of the Refunded Bonds were used and none of
the proceeds of the Bonds will be used to reimburse the Borrower for an
expenditure paid prior to the date which is 60 days prior to the date on which
the Issuer adopted a reimbursement resolution with respect to the Project. Any
such reimbursement that is allocated to proceeds of the Bonds is referred to
herein as a “Reimbursement Allocation.” With respect to the Preliminary
Expenditures, the Borrower represents and covenants as follows:

-2-

--------------------------------------------------------------------------------

 

     (a) All Preliminary Expenditures relate to architectural, engineering,
surveying, soil testing, bond issuance and similar costs that were incurred
prior to commencement of construction, or acquisition of the Project and do not
include any costs related to land acquisition, site preparation and similar
costs incident to commencement of construction.

     (b) All Preliminary Expenditures represent (i) costs of a type that would
be properly chargeable to a capital account under the Code (or would be so
chargeable with a proper election) under federal income tax principles if the
Borrower were treated as a corporation subject to Federal income taxation or
(ii) a cost of issuing the Bonds.

     (c) Funds corresponding to Gross Proceeds used to reimburse a Preliminary
Expenditure will not be used within one year after making any Reimbursement
Allocation in a manner that results in the creation of Replacement Proceeds of
the Bonds or any other issue. The preceding sentence does not apply to amounts
deposited in a bona fide Bond Fund.

     (d) No Reimbursement Allocation will employ any action that (A)(i) enables
the Borrower to exploit the difference between tax-exempt and taxable interest
rates to obtain a material financial advantage and (ii) overburdens the
tax-exempt bond market to avoid arbitrage restrictions or (B) avoids the
restrictions under Sections 142 through 147 of the Code.

     Section 1.4 Working Capital. (a) All of the proceeds of the Bonds, plus
investment earnings, will be used, directly or indirectly, to pay principal or
interest on the Bonds or to refinance costs of a type that were and are properly
chargeable to a capital account (or would be so chargeable with a proper
election) under general federal income tax principles in effect at the time the
cost was paid, other than the following:

     (i) an amount not to exceed five percent of the Sale Proceeds of the Bonds
for working capital expenditures directly related to capital expenditures
financed by the Refunded Bonds;

     (ii) payments of interest on the Bonds for a period commencing on the date
of issuance of the Bonds and ending on the later of the date three years after
such date or one year after the date on which the Project is placed in service;

     (iii) costs of issuing the Bonds and qualified administrative costs of
investments within the meaning of Sections 1.148-5(e)(2)(i), 1.148-5(e)(2)(ii)
or 1.148-5(e)(3) of the Regulations;

     (iv) payments of rebate or yield reduction payments made to the United
States under the Regulations;

     (v) principal of or interest on an issue paid from unexpected excess sale
or investment proceeds; and

-3-

--------------------------------------------------------------------------------

 

     (vi) principal of or interest on an issue paid from investment earnings on
a reserve or replacement fund that are deposited in a bona fide debt service
fund.

     (b) No Gross Proceeds may be spent for non-capital purposes pursuant to
this Section if the expenditure merely substitutes Gross Proceeds for other
amounts that would have been used to make such expenditures in a manner that
gives rise to Replacement Proceeds.

     Section 1.5 Consequences of Contrary Expenditure. The Borrower acknowledges
that if Gross Proceeds of the Bonds are spent for non-capital purposes other
than as permitted by Section 1.4 hereof, a like amount of then-available funds
of the Borrower will be treated as unspent Gross Proceeds, which, among other
things, may be subject to the yield restrictions described in Section 5.2 hereof
and rebate described in Article III hereof.

     Section 1.6 Abusive Transactions. Neither the Issuer, the Borrower nor any
member of the same Controlled Group of either of the foregoing has employed a
device or entered into any arrangements or understandings in connection with the
issuance of the Bonds, or the acquisition or construction of the Project, or in
connection with any transaction or series of transactions related to the
issuance of the Bonds, or the acquisition or construction of the Project, to
obtain a material financial advantage based on arbitrage. Neither the Issuer,
the Borrower nor any member of the same Controlled Group of either of the
foregoing will realize any material financial advantage based on arbitrage in
connection with the issuance of the Bonds or in connection with any transaction
or series of transactions related to the issuance of the Bonds or the
acquisition or construction of the Project. In particular, neither the Issuer,
the Borrower nor any member of the same Controlled Group as either of the
foregoing has or will receive a rebate or credit resulting from any payments
having been made in connection with the issuance of the Bonds or the acquisition
or construction of the Project.

     Section 1.7 Hedges; Bonds Not Hedge Bonds. The Bonds will not be hedge
bonds as defined in Section 149(g) of the Code since the Issuer and the Borrower
reasonably expect that at least 85% of the spendable proceeds of the Bonds will
be used to carry out the governmental purposes of the issue within a three year
period beginning on the Delivery Date and not more than 50% of the proceeds of
the Bonds are or will be invested on investments (other than Tax Exempt
Obligations) having a yield that is substantially guaranteed for four years or
more.

the “Funds”).

     (c) On the Closing Date the total purchase price of the Bonds, as shown in
(a) above ($5,573,700) will be deposited in the Project Fund.

     (d) All income derived from the investment of moneys on deposit in any of
the Funds created under the Indenture shall be credited to such Fund. The
Borrower anticipates that there will be no investment earnings with respect to
the Project Fund because forthwith upon the issuance of the Bonds and the
deposit of the proceeds thereof

-5-

--------------------------------------------------------------------------------

 

into the Project Fund all moneys in the Project Fund will be transferred to the
Prior Trustee for application to the redemption in whole of the Refunded Bonds,
in accordance with the provisions of the Prior Indenture.

     (e) Costs of issuance incurred in connection with the issuance of the Bonds
(other than costs of issuance in an amount not to exceed 2.00% of the proceeds
of the Bonds) will be paid by the Borrower from sources other than proceeds of
the Bonds or moneys held by the Prior Trustee under the provisions of the Prior
Indenture for payment of the Refunded Bonds.

     (f) Payments received by the Trustee from draws on the Letter of Credit to
pay the principal of and premium, if any, and interest on the Bonds will be
deposited in the Bond Fund created under the Indenture. Moneys on deposit in the
Bond Fund will be used to pay interest and principal on the Bonds.

     (g) Interest on the Bonds and principal due at maturity will be paid from
the Bond Fund established under the Indenture. The redemption price of the Bonds
will also be paid from the Bond Fund.

     (h) Moneys received from draws under the Letter of Credit to pay the
Purchase Price of Tendered Bonds shall be deposited into the Bond Fund on the
date that payment of the Purchase Price is due and moneys received from the
sale, remarketing or placement of Tendered Bonds shall be paid to the Bank to
reimburse amounts drawn under the Letter of Credit to pay the Purchase Price of
the Bonds.

     Section 2.2 Purpose of the Bond Fund. The Bond Fund will be used primarily
to achieve a proper matching of revenues and earnings with principal and
interest in each bond year. It is expected that the Bond Fund will be depleted
at least once a year, except for a reasonable carry over amount not to exceed
the greater of (i) one year’s earnings, in the aggregate, on the investment of
moneys in the Bond Fund for the immediately preceding bond year or (ii) in the
aggregate, one-twelfth (1/12th) of the principal and interest payments on the
Bonds for the immediately preceding bond year.

     Section 2.3 Purpose of the Project Fund. At closing, proceeds of the Bonds
in the amount of $5,573,700 will be credited to the Project Fund. Moneys
deposited in the Project Fund are to be transferred forthwith upon such deposit
to the Prior Trustee for application to the redemption in whole of the Refunded
Bonds on the Call Date.

     Section 2.4 No Replacement, Sinking or Pledged Funds.

     (a) Except as otherwise provided in Sections 2.1 and 2.2 hereof, after the
issuance of the Bonds on this date, neither the Issuer, the Borrower, nor any
member of the same Controlled Group of which the Issuer or the Borrower is a
member has on hand any property, including cash and securities, that has a
sufficiently direct nexus to the purposes financed with the Bonds to support the
conclusion that the amounts derived from such property would have been used for
such purposes if the Bonds had not been issued.

-6-

--------------------------------------------------------------------------------

 

     (b) Except as otherwise provided in Sections 2.1 and 2.2 hereof, neither
the Issuer, the Borrower, nor any member of the same Controlled Group of which
the Issuer or the Borrower is a member has established or expects to establish
any funds or accounts in which any Replacement Proceeds will be deposited.

     (c) Except as otherwise provided in Sections 2.1 and 2.2 hereof, no
property has been or is expected to be pledged or otherwise restricted (no
matter where held or the source thereof) to provide reasonable assurance, in the
event the Issuer, the Borrower, or any member of the same Controlled Group of
which the Issuer or the Borrower is a member encounters financial difficulty, of
its availability to be used, directly or indirectly, for the payment of amounts
due or to become due on the Bonds or the Loan Agreement. No compensating
balance, negative pledge or similar arrangement exists with respect to, in any
way, the Bonds, or the Loan Agreement.

     (d) No portion of the Bonds is being issued solely for the purpose of
investing the proceeds thereof at a yield higher than the Yield on the Bonds.

     (e) The term of the Bonds is not longer than is reasonably necessary for
the governmental purposes of the Bonds. The weighted average maturity of the
Bonds as determined by the Underwriter is 9.181 years. The proceeds of the Bonds
will be applied to pay the costs of refunding the Refunded Bonds, as shown on
Exhibit A hereto. The reasonably expected remaining economic life of the
portions of the Project financed with proceeds of the Refunded Bonds is
26.75 years. The weighted average maturity of the Bonds does not exceed 120% of
the average reasonably expected economic life of the property refinanced with
the proceeds of the Bonds.

     Section 2.5 No Grants. No proceeds of the Bonds are being used to make
grants to any person.

     Section 2.6 Letter of Credit.

     (a) The Letter of Credit is essential in marketing the Bonds at the
Variable Rate, including the initial Variable Rate specified in the Indenture,
(ii) the absence of the Letter of Credit would materially affect in an adverse
manner the Variable Rates at which the Bonds have or will be sold (either
initially or by remarketing), and (iii) the present value of the fees for the
Letter of Credit paid to the Bank is less than the present value of the interest
reasonably expected to be saved as a result of using the Letter of Credit to
secure the Bonds, using as a discount rate the expected yield on the Bonds.

     (b) Neither the Issuer nor the Borrower, nor any member of the same
Controlled Group as the Issuer or the Borrower is a Related Person as defined in
Section 144(a)(3) of the Code to the Bank. Other than the fees paid to the Bank,
neither the Bank, nor any person who is a Related Person to the Bank within the
meaning of Section 144(a)(3) of the Code will use any Gross Proceeds.

--------------------------------------------------------------------------------

 

ARTICLE III

REBATE FUND; ARBITRAGE REQUIREMENT

     Section 3.1 Rebate Fund. The Rebate Fund created in the Indenture shall be
continuously held, invested, expended and accounted for in accordance with this
Agreement; provided, however, that the Rebate Fund need not be maintained if the
Issuer, the Trustee, and the Borrower shall have received an opinion of Bond
Counsel acceptable to the Trustee to the effect that failure to maintain the
Rebate Fund shall not cause the Bonds to become arbitrage bonds within the
meaning of Section 148 of the Code or otherwise adversely affect the exclusion
from gross income of interest on the Bonds for federal income tax purposes.
Moneys in the Rebate Fund shall not constitute a part of the “trust estate” held
for the benefit of the Bondholders, or, except as provided in Section 9.2
hereof, for the benefit of the Issuer, or the Borrower. Except as provided in
the Regulations, moneys in the Rebate Fund (including earnings and deposits
therein) shall be held in trust by the Trustee for future payment to the United
States government as required by the Regulations and as contemplated under the
provisions of this Agreement.

     Section 3.2 Issuer’s and Borrower’s Covenants; Records. The Issuer and the
Borrower covenant and agree to take such actions and the Borrower covenants and
agrees to make, or cause to be made, all calculations, transfers and payments
that may be necessary to comply with the rebate requirements contained in
Section 148(f) of the Code with respect to the Bonds. The Borrower will make, or
cause to be made, rebate payments in accordance with law with respect to the
Bonds. Bond Counsel has provided a letter attached hereto as Exhibit C
concerning the principles set forth in certain Regulations regarding rebate. The
Borrower agrees that the Computation Dates for the Bonds will be the day
immediately preceding the anniversary date of the Dated Date each year beginning
in the year 2005, and, if all of the Bonds are paid in full prior to such dates,
the date of such payment.

     The Trustee and the Borrower agree to keep and retain or cause to be kept
and retained, until the date six years after the final payment with respect to
the Bonds, adequate records with respect to the investment of all Gross Proceeds
and amounts in the Rebate Fund, if any. Such records shall include (i) purchase
price; (ii) purchase date; (iii) type of investment; (iv) accrued interest paid;
(v) interest rate (if applicable); (vi) principal amount; (vii) maturity date;
(viii) interest payment date (if applicable); (ix) date of liquidation;
(x) amounts received upon liquidation. If any investment becomes Gross Proceeds
of the Bonds on a date other than the date such investment is purchased, the
records required to be kept shall include the fair market value of such
investment on the date it becomes Gross Proceeds. If any investment is retained
after the date the last Bond is retired, the records required to be kept shall
include the fair market value of such investment on the date the last Bond is
retired. Amounts will be segregated wherever held in order to maintain these
records.

     Section 3.3 Fair Market Value.

     (a) In General. Whenever the Borrower shall purchase or sell, or cause any
party to purchase or sell, any Nonpurpose Investment, such purchase or sale
shall be made only at the fair market value of such Nonpurpose Investment.
Except as described below, the fair market value of a Nonpurpose Investment is
the price determined by

-8-

--------------------------------------------------------------------------------

 

reference to an established securities market for the Investment, as of the date
on which a contract to purchase or sell the Investment becomes binding, at which
a willing buyer would purchase the investment from a willing seller in a bona
fide, arm’s length transaction. The price shall not be adjusted to take into
account “administrative costs” of the investment (within the meaning of
Section 1.148-5(e)(1) of the Regulations) except as permitted by
Section 1.148-5(e)(2) of the Regulations. The fair market value of a United
States Treasury obligation purchased directly from the United States Treasury is
its purchase price.

     (b) Guaranteed Investment Contracts. In the case of a Nonpurpose Investment
that has specifically negotiated withdrawal or reinvestment provisions and a
specifically negotiated interest rate, including an agreement to supply
investments on two or more future dates, the fair market value is its purchase
price if the following conditions are satisfied:

     (1) The Borrower or its agent makes a bona fide solicitation for the
purchase of the Investment that satisfies all of the following requirements:

     (a) The bid specifications were in writing and were timely forwarded to
potential providers.

     (b) The bid specifications included all material terms of the bid. A term
is material if it may directly or indirectly affect the yield or the cost of the
Investment.

     (c) The bid specifications included a statement notifying potential
providers that submission of a bid is a representation that the potential
provider did not consult with any other potential provider about its bid, that
the bid was determined without regard to any other formal or informal agreement
that the potential provider has with the Issuer or any other person (whether or
not in connection with the Bonds), and that the bid is not being submitted
solely as a courtesy to the Borrower or any other person for purposes of
satisfying the requirements of paragraph (2) below.

     (d) The terms of the bid specifications are commercially reasonable. A term
is commercially reasonable if there is a legitimate business purpose for the
term other than to increase the purchase price or reduce the yield of the
Investment.

     (e) The terms of the solicitation take into account the Borrower’s
reasonably expected deposit and drawdown schedule for the amounts to be
invested.

     (f) All potential providers had an equal opportunity to bid. For example,
no potential provider was given the opportunity to review other bids (i.e., a
last look) before providing a bid.

-9-

--------------------------------------------------------------------------------

 

     (g) At least three reasonably competitive providers were solicited for
bids. A reasonably competitive provider is a provider that has an established
industry reputation as a competitive provider of the type of investments being
purchased.

     (2) The bids received must meet all of the following requirements:

     (a) Bids are received from at least three providers that were solicited
under a bona fide solicitation meeting the requirements of paragraph (1) above
and that do not have a material financial interest in the Bonds. The Underwriter
is deemed to have a material financial interest in the Bonds until 15 days after
the date hereof. In addition, any entity acting as a financial advisor with
respect to the purchase of the Investment at the time the bid specifications are
forwarded to potential providers has a material financial interest in the Bonds.
A provider that is a related party to a provider that has a material financial
interest in the Bonds is deemed to have a material financial interest in the
Bonds.

     (b) At least one of the three bids described in the preceding paragraph is
from a reasonably competitive provider, within the meaning of paragraph (1)(g)
above.

     (c) The agent soliciting the bids does not bid to provide the Investment.

     (3) The winning bid is the highest yielding bona fide bid (determined net
of any broker’s fees).

     (4) The amount paid to the agent soliciting the bids does not exceed the
amount authorized by the applicable Regulations.

     (c) Certificates of Deposit. In the case of a certificate of deposit that
has a fixed interest rate, a fixed payment schedule and a substantial penalty
for early withdrawal, the fair market value of the certificate is its purchase
price if the yield on the certificate is not less than (i) the yield on
reasonably comparable direct obligations of the United States, and (ii) the
highest yield that is published or posted by the provider to be currently
available from the provider on reasonably comparable certificates of deposit
offered to the public.

     (d) Commingled Funds. Gross Proceeds of the Bonds may be invested in a
Commingled Fund only if the Commingled Fund complies with the special accounting
rules set forth at Section 1.148-6(e) of the Regulations. Generally, this
requires that, not less frequently than as of the close of each fiscal period,
all payments and receipts (including deemed payments and receipts) on
investments held by a Commingled Fund must be allocated (but not necessarily
distributed) among the different investors in the fund in accordance with a
consistently applied, reasonable ratable allocation method. For this purpose,
the term “investor” means each different source of funds invested in a
Commingled Fund, and the term “fiscal period” means any consistent fiscal period
that does not exceed 3 months.

-10-

--------------------------------------------------------------------------------

 

ARTICLE IV

ADDITIONAL PAYMENTS

     In addition to the amounts provided in this Agreement, the Borrower hereby
agrees to pay to the Trustee for deposit into the Rebate Fund for payment to the
United States any amount which under the Regulations must be deposited in the
Rebate Fund for payment to the United States with respect to the Bonds, but
which is not available under the Indenture for transfer to the Rebate Fund for
payment to the United States.

-11-

--------------------------------------------------------------------------------

 

ARTICLE V

YIELD AND YIELD LIMITATIONS

     Section 5.1 Issue Price. The Underwriter has certified that at the time it
agreed to market the Bonds, based upon its assessment of the then prevailing
market conditions, it reasonably expected that all Bonds would be sold on the
date hereof to the public (excluding bond houses, brokers or similar persons or
organizations acting in the capacity of underwriters or wholesalers) at par.

     Section 5.2 Yield Limits and Election.

     (a) All Gross Proceeds and all amounts in the Rebate Fund, to the extent
not exempted in (b) below, shall be invested at market prices and at a yield
(after taking into account any yield reduction payments to the extent permitted
by and made pursuant to Section 1.148-5(c) of the Regulations) not in excess of
the yield on the Bonds, plus, for amounts in the Project Fund only, 1/8 of 1%.

     (b) The following may be invested without yield restriction:

     (i) amounts invested in Tax-Exempt Obligations (to the extent permitted by
the Indenture);

     (ii) amounts in the Rebate Fund;

     (iii) amounts deposited in the Bond Fund that have not been on deposit
under the Indenture for more than 13 months, so long as such funds continue to
qualify as bona fide debt service funds as described in Section 2.2 hereof;

     (iv) [Intentionally Omitted]

     (v) [Intentionally Omitted]

     (vi) all amounts for the first 30 days after they become Gross Proceeds;

     (vii) all amounts derived from the investment of proceeds for a period of
one year from the date received; and

     (viii) an amount not to exceed $100,000 (a “Minor Portion”).

     Section 5.3 Fees of the Bank. Based on the certifications of the
Underwriter and the Bank, which the Borrower and the Issuer have no reason to
believe are untrue, and the representations contained in this Agreement the fees
of the Bank for the Letter of Credit will be treated as interest on the Bonds
for purposes of calculating Bond Yield. Neither the Borrower, the Issuer nor any
member of the same Controlled Group of the Borrower or the Issuer is a related
person to the Bank within the meaning of Section 144(a)(3) of the Code. Other
than the fees paid to the Bank, neither the Bank, nor any person who is a
Related Person to the Bank within the meaning of Section 144(a)(3) of the Code
will use any proceeds received from the sale of the Bonds or investment earnings
thereon.

-12-

--------------------------------------------------------------------------------

 

     Section 5.4 Continuing Nature of Yield Limits. Subject to Section 9.5, once
moneys are subject to the yield limits of Section 5.2, they remain yield
restricted until they cease to be Gross Proceeds.

     Section 5.5 Debt Service on the Loan Agreement. Payments of debt service on
the Loan Agreement, exactly equal debt service payments on the Bonds. No fees
will be payable to the Issuer in connection with the issuance of the Bonds in an
amount in excess of one-eighth of one per cent per annum. Expenses incurred by
the Issuer in connection with the issuance of the Bonds will be reimbursed by
the Borrower. The earnings and profits of any temporary investment of amounts
held under the Indenture will accrue to the Borrower and not to the Issuer. It
is not expected that payments will be made sooner than necessary under the Loan
Agreement, provided that the Borrower may make early payments to effect the
redemption of the Bonds.

     Section 5.6 Other Payments Relating to the Bonds. The Issuer will require
the Borrower to reimburse it for a portion or all of its costs relating to the
issuance of the Bonds.

     Except for (a) costs of issuance relating to the Bonds, (b) fees and
expenses of the Trustee, as set forth in the Indenture, and (c) the fees of the
Issuer as set forth above, no consideration, in cash or in kind, is being or
will be paid by any person to any person in connection with or relating to
issuing, carrying or redeeming the Bonds or issuing, carrying or repaying the
amounts owing under the Loan Agreement.

     Section 5.7 Calculation of Bond Yield. The Bonds are a “variable yield
issue”, as defined in Section 1.148-1(b) of the Regulations. Accordingly, Bond
Yield will be computed separately for each computation period. As provided in
Section 1.148-4(c) of the Regulations, the Bond Yield for each computation
period will be the discount rate that, when used in computing the present value,
as of the first day of the computation period, of all the payments of principal
and interest and fees for qualified guarantees that are attributable to the
computation period, produces an amount equal to the present value, using the
same discount rate, of the aggregate issue price of the Bonds as of the first
day of the computation period. Such payments will include principal and interest
to be paid on the Bonds and fees paid to the Bank for the Letter of Credit, as a
qualified guarantee. As required in Section 1.148-4(f) of the Regulations and
based in part on the Underwriter’s Certificate, it is determined that, computed
over the term of the Letter of Credit, the present value of the savings
resulting from the Letter of Credit (i.e., the present value of the difference
between the interest payable on the Bonds and the interest which would be
payable on the Bonds if the Letter of Credit had not been obtained, utilizing a
discount rate equal to the yield on the Bonds and taking into account the fees
for the Letter of Credit) is greater than the present value of the aggregate
fees paid to the Bank. Further, as evidenced by the Closing Certificate of the
Bank, (i) the Letter of Credit unconditionally shifts the ultimate credit risk
for the Bonds to the Bank (ii) the fees and charges to be paid to the Bank for
the Letter of Credit do not exceed a reasonable charge for the transfer of
credit risk and are comparable to fees and charges charged by other guarantors
in comparable transactions; and (iii) the fees and charges to be paid to the
Bank for the Letter of Credit do not include any direct or indirect payment for
a cost, risk or other element that is not customarily borne by guarantors of
tax-exempt obligations.

-13-

--------------------------------------------------------------------------------

 

     In the event that the Bonds are converted to a Fixed Rate, on the
Conversion Date, the Bonds will be treated (for purposes of computing the Bond
Yield) as having been retired on that date and reissued as a “fixed yield
issue.” Following the Conversion Date the Bond Yield on the Bonds will be
calculated, as provided in Section 1.148-4(b) of the Treasury Regulations, as
that discount rate which when used in computing the present value as of the
Conversion Date of all unconditionally payable payments of principal, interest,
and fees paid or reasonably expected to be paid for qualified guarantees on the
Bonds, produces an amount which is equal to the present value, using the same
discount rate, of the aggregate issue price thereof.

     Section 5.8 Yield Reduction Payments. The Bonds qualify for the special
yield reduction rule of Section 1.148-5(c) of the Regulations prior to the
Conversion Date because the Bonds are a variable yield issue. The Issuer may
determine to make yield reduction payments to the United States under Section
1.148-5(c) of the Regulations with respect to Nonpurpose Investments held in the
Project Fund, and such payments may be taken into account as a payment for that
Nonpurpose Investment which reduces the yield thereon. Payments of Rebate under
Section 3.2 hereof may be taken into account as yield reduction payments to the
extent permitted by Section 1.148-5(c) of the Regulations.

BORROWER PROJECT AND TAX COVENANTS

     Section 6.1 Use of Proceeds.

     (a) Substantially all (that is, not less than 95%) of the proceeds of the
Refunded Bonds were used for the acquisition, construction, reconstruction or
improvement of land or property of a character subject to the allowance for
depreciation under the Internal Revenue Code.

     (b) Not less than 95% of the proceeds of the Refunded Bonds were used to
provide a facility which is used in the manufacturing or production of tangible

condition of the property). An office shall not be described in the preceding
sentence unless (a) the office is located on the premises of the manufacturing
facility, and (b) not more than a de minimis amount of the functions to be
performed at such office is not directly related to the day-to-day operations at
such facility. For purposes of the first sentence of this paragraph, the term
“manufacturing facility” includes facilities which are directly related and
ancillary to a manufacturing facility (determined without regard to this
sentence) if (i) such facilities are located on the same site as the
manufacturing facility, and (ii) not more than 25 percent of the net proceeds of
the Bonds are used to provide such facilities.

     (c) The aggregate of (i) capital expenditures with respect to facilities in

the Refunded Bonds, together with the then outstanding principal amounts of any
“prior issues,” plus (iii) the capital expenditures made with respect to
facilities in or attributable to the City by the Borrower or such other
principal user of the Project Facilities or by any person related to the
Borrower or such other principal user within a period of 36 months after the
date of issuance of the Refunded Bonds, whether allocable or attributable to the
Project Facilities or any other facility within or attributable to the City, all
as such terms are used in Section 144(a) of the Internal Revenue Code of 1986,
and regulations thereunder, did not exceed $10,000,000.

     (d) The Borrower did not use any portion of the proceeds of the Refunded
Bonds and shall not use any portion of the proceeds of the Bonds to provide any
private or commercial golf course facility, country club, massage parlor, tennis
club, skating facility (including roller skating, skateboard or ice skating),
racquet sports facility (including any handball or racquetball court), hot tub
facility, suntan facility, racetrack, airplane, skybox, or other private luxury
box, any facility primarily used for gambling, or any store the principal
business of which is the sale of alcoholic beverages for consumption off
premises, and the Borrower does not expect that the Project Facilities, or any
part thereof, will be used for any of such purposes.

-15-

--------------------------------------------------------------------------------

 

     (e) The Borrower used less than 25 percent of the proceeds of the Refunded
Bonds either directly or indirectly to finance the acquisition of land (or any
interest therein), and used not more than 25 percent of the proceeds of the
Refunded Bonds and of the Refunded Bonds to provide a facility the primary
purpose of which is retail food or beverage service, automobile sales or
service, or the provision of recreation or entertainment, and the Borrower does
not expect that the Project Facilities, or any portion thereof, shall
subsequently be used primarily for any of such purposes.

     (f) None of the proceeds of the Refunded Bonds were used for the
acquisition of any existing building or other used property, unless at least
15 percent (or in the case of a structure other than a building 100 percent) of
the cost of acquisition of such existing property financed by proceeds of the
Refunded Bonds was spent for rehabilitation expenditures, within the meaning of
Section 147(d) of the Internal Revenue Code, within two years of the date of
acquisition or, if later, the date of issuance of the Refunded Bonds.

     (g) The aggregate outstanding amount of tax-exempt facility-related bonds
allocated to the Borrower (including related persons) or any other principal
user of the Project Facilities (including related persons) when added to the
aggregate amount of the Series 2004 Bonds allocated to the Borrower (including
related persons) or such other principal user (including related persons), all
as such terms are defined in Section 144(a) of the Internal Revenue Code of 1986
(or the applicable predecessor Section of the Internal Revenue Code of 1954, as
amended prior to the enactment of the Tax Reform Act of 1986), does not exceed
$40,000,000.

     (h) The Borrower is not a principal user, nor related to any principal
user, of any facilities other than the Project Facilities within the City which
were acquired in whole or in part, directly or indirectly, by the issuance of
tax-exempt bonds which are outstanding on the date hereof, within the meaning of
Section 144 of the Internal Revenue Code of 1986 and regulations thereunder. No
tax-exempt bonds issued with respect to the Project Facilities are outstanding
as of the date hereof except for the Refunded Bonds.

     (i) The weighted average maturity of the Series 2004 Bonds does not exceed
120% of the average weighted economic life of the Project Facilities.

     (j) The weighted average maturity of the Series 2004 Bonds does not exceed
the remaining weighted average maturity of the Refunded Bonds.

     (k) The original principal amount of the Series 2004 Bonds is in an amount
not greater than the current outstanding principal amount of the Refunded Bonds.
The principal amount of the Series 2004 Bonds is not larger than the amount
necessary to cause the Refunded Bonds to be redeemed in whole, in accordance
with the provisions of the Prior Indenture and in accordance with the provisions
hereof. The entire gross proceeds of the Series 2004 Bonds ($5,630,000) are to
be expended solely for the payment and discharge on the Call Date of the
outstanding principal amount of the Refunded Bonds. The Refunded Bonds will be
redeemed in whole within 90 or fewer days from the date of issuance of the
Series 2004 Bonds.

such disposition will not adversely affect the validity of the Bonds or any
exemption of the interest on the Bonds from federal income taxation to which
such Bonds would otherwise be entitled, (b) prior to such sale, lease, or other
disposition, there is delivered to the Trustee an Officer’s Certificate of the
Borrower, stating that, in the judgment of such officer, (1) such property has
become inadequate, obsolete, or worn out, (2) such property has been owned and
used by the Borrower for a period not less than the reasonably expected economic
life of the property as set forth herein, and (3) that any amounts received by
the Borrower upon such disposition will be applied by the Borrower in such
manner as will not adversely affect the validity of the Bonds or any exemption
from federal income taxation to which the interest on the Bonds would otherwise
be entitled, or (c) the Borrower provides the Trustee and the Issuer with an
Officer’s Certificate of the Borrower, stating that (1) all sales, leases, or
other dispositions in excess of the amount set forth above were made during the

request that, in connection with the delivery of the certificate described in
subsection (b) or (c) above, the Borrower, deliver an opinion of Bond Counsel to
the effect that such disposition will not have an adverse effect on the validity
of the Bonds or any exemption from federal income taxation to which the interest
on the Bonds would otherwise be entitled.

     Section 9.4 Future Events. The Issuer, the Trustee, and the Borrower
acknowledge that any changes in facts or expectations from those set forth
herein may result in different yield restrictions or rebate requirements and
agree that Bond Counsel will be contacted if such changes do occur.

     Section 9.5 Permitted Changes; Opinion of Bond Counsel. The yield
restrictions contained in Section 5.2, or any other restriction or covenant
contained herein need not be observed or may be changed if the Issuer, the
Trustee and the Borrower receive an opinion of Bond Counsel to the effect that
such noncompliance or change will not adversely affect the exclusion from gross
income of interest on the Bonds for federal income tax purposes.

     Section 9.6 Severability. If any clause, provision or section of this
Agreement is ruled invalid by any court of competent jurisdiction, the
invalidity of such clause, provision or section shall not affect any of the

to establish the expectations of the Issuer regarding the expenditure of the
proceeds of the Bonds, pursuant to Section 148 of the Code and Section
1.148-2(b) of the Regulations. The Issuer and its signatory have made no
independent investigation of the matters stated herein. The expectations of the
Issuer described herein are based upon the provisions of the Loan Agreement and
Indenture and upon the representations of the Underwriter and the Borrower as to
the matters contained in this Agreement and in their certificates attached
hereto. Nothing has come to the attention of the Issuer which would lead it to
believe that any of the expectations described in this Agreement, and any of the
expectations of the Borrower and Underwriter described in their respective
certificates, are not reasonable or correct. No facts, estimates, conditions or
circumstances that would materially alter the expectations described in this
Agreement are known to the Issuer.

Procedure 62-21, 1962-2 C.B. 418, in the case of structures.     (2)   This
applies only if the asset has already been placed in service as of the date
hereof. The term “Prior Years” refers to the number of years prior to the date
hereof that an asset was placed in service.     (3)   This applies only if the
asset has not yet been placed in service as of the date the Bonds are issued.
The term “Future Years” refers to the number of years after the Closing Date
that an asset is expected to be placed in service.     (4)   The “Adjusted
Economic Life” of an asset is equal either to the Economic Life minus Prior
Years or the Economic Life (for Future Years), whichever is applicable.     (5)
  The term “Asset Cost” refers to the purchase price of the asset to the
Borrower.     (6)   The product of the Adjusted Economic Life and Asset Cost.

     The “average reasonably expected economic life” of the Project Facilities
financed or refinanced by the Bonds is 26.75 years which is computed by dividing
the total product of Adjusted Economic Life and the Asset Cost, or $149,077,750
by the total Asset Cost for assets so financed or refinanced, or $5,573,000. For
this purpose, the reasonably expected economic life of each asset has been
determined as of the later of (i) the Closing Date, or (ii) the date on which
such asset is expected to be placed in service.

UNDERWRITER’S CERTIFICATE AND

RECEIPT FOR BONDS

        I, the undersigned, a duly qualified and acting officer of Northland
Securities, Inc. (the “Underwriter”), hereby acknowledge that on the date
hereof, upon payment of the purchase price therefor, I received on behalf of the
foregoing the fully registered bonds generally described as the $5,630,000 City
of Chaska, Minnesota Variable Rate Demand Purchase Revenue Bonds (Lifecore
Biomedical, Inc. Project), Series 2004 (the “Bonds”).

        In such connection, I hereby certify, as follows:

  1.   The Underwriter, Lifecore Biomedical, Inc. (the “Borrower”) and the City
of Chaska, Minnesota (the “Issuer”) executed on August 19, 2004 a Bond Purchase
Agreement (the “Purchase Agreement”) in connection with the Bonds. The Purchase
Agreement has not been modified since its execution.     2.   The Underwriter
hereby confirms that the first offering price at which all of the principal
amount of the Bonds has been placed is equal to the par amount of the Bonds. The
initial offering price of the Bonds to the public (excluding bond houses,
brokers and other intermediates) was equal to 100% of the principal amount of
the issue, determined without regard to administrative costs incurred in the
issuance of the Bonds (such as underwriting, legal and accounting fees). A
substantial amount of the Bonds of each maturity was sold at the initial
offering price to the initial purchasers of the Bonds (excluding bond houses,
brokers and other intermediaries).     3.   The Underwriter has not and will not
receive any compensation with respect to or related to the issuance of the Bonds
in excess of the Underwriter’s fee (except for a fee in the first six months as
the Remarketing Agent equal to one-eighth of one percent per annum of the
aggregate outstanding principal amount of Bonds, which shall be prorated for the
period from closing to February 1, 2005).     4.   The initial Variable Rate (as
set forth in Section 2.02(c) of the Indenture) set by the Remarketing Agent for
each of the Bonds is    % and represents the lowest rate that enabled such Bond
to be marketed at par on the date hereof.

B-1

--------------------------------------------------------------------------------

 

  5.   If the Bonds were not secured by the Letter of Credit, the interest rates
at which the Bonds could be sold or remarketed would be materially adversely
affected.     6.   Payment of the principal of and interest on the Bonds at the
stated maturities thereof is secured by the Letter of Credit issued by M&I
Marshall & Ilsley Bank (the “Bank”). Based upon our experience, the fees charged
by the Bank for the Letter of Credit is a reasonable charge for the transfer of
the credit risk with respect to the Bonds to the Bank and does not represent in
whole or in part direct or indirect payments for a cost, risk or other element
that is not customarily borne by a credit facility provider providing similar
credit enhancement for the payment of principal of and interest on tax-exempt
bonds. The present value of such fees paid is less than the present value of the
interest to be saved as a result of the security afforded by the Letter of
Credit. In determining the present value savings, the expected yield on the
Bonds (determined without regard to costs of issuance of the Bonds) has been
used as the discount rate.     7.   The Remarketing Agent is required to use its
best efforts to remarket Bonds that are tendered for purchase and not retired.  
  8.   The Underwriter has calculated the weighted average maturity of the Bonds
to be 9.181 years.     9.   The Bonds have been offered and sold by the
Underwriter solely to institutional investors in transactions that are exempt
from registration under the Securities Act of 1933, as amended.

        All terms not defined herein shall have the same meanings as in the Tax
Exemption Agreement dated as of August 1, 2004 among the Issuer, the Borrower
and Wells Fargo Bank, National Association, as trustee.

     Dated: August      , 2004

City of Chaska, Minnesota

Wells Fargo Bank, National Association,
   as Trustee
Minneapolis, Minnesota

Lifecore Biomedical, Inc.
Chaska, Minnesota

     
Re:
  $5,630,000 Variable Rate Demand Purchase Revenue Bonds

  (Lifecore Biomedical, Inc. Project), Series 2004

  City of Chaska, Minnesota

  (the “Bonds”)

Ladies and Gentlemen:

     We have acted as Bond Counsel in connection with the issuance on this date
of the above-referenced Bonds (the “Bonds”). In a Tax Exemption Agreement
delivered by each of you this date (the “Tax Agreement”), the City of Chaska,
Minnesota (the “Issuer”), Wells Fargo Bank, National Association, as trustee
(the “Trustee”) and Lifecore Biomedical, Inc. (the “Borrower”) have agreed to
comply with the arbitrage rebate requirements of Section 148 of the Internal
Revenue Code of 1986. The purpose of this letter is to set out generally the
rules that you must follow to comply with the Tax Agreement. This letter does
not describe how to actually compute the amount to be rebated to the United
States, and due to the complexity involved, the computation will, in all
likelihood, require consultation with an expert.

     The Internal Revenue Service has issued final regulations relating to
arbitrage and rebate matters. This letter is based on these regulations which
are subject to change in the future. Such changes may require further
recalculation of rebate amounts. For these reasons, it is very important for you
and your tax advisors to keep abreast of developments in this area.

     The following advice is based on factual information contained in the Tax
Agreement. If the facts or expectations stated therein change, please call us to
determine whether this results in a change in the following rules. Please note
that the rules governing permissible yield on investments set forth in the Tax
Agreement are in addition to the rebate rules, and although you might be allowed
to earn a yield in excess of Bond Yield under the yield rules, such excess may

C-1

--------------------------------------------------------------------------------

 

still be required to be rebated. In some cases, the payment of rebate may assist
in compliance with the yield restriction requirements. Thus, rebate compliance
and yield restriction may, in certain circumstances, operate together rather
than independently. In any case, rebate compliance is essential to the
maintenance of the tax exemption of interest on the Bonds even if no amounts are
subject to yield restriction. Terms not defined herein shall have the meanings
set forth in the Tax Agreement. Yield is defined in Article VII of the Tax
Agreement.

     General Rule. Except in the case of certain exceptions as summarized below,
every five years and at the final retirement of all of the Bonds, you must
compute and pay (as described below) to the United States the difference (the
“Excess Earnings”) between the amount earned on all investments and
reinvestments of Gross Proceeds (as defined in the Tax Agreement) of the Bonds
(“Actual Earnings”) and the amount that would have been earned if Gross Proceeds
had been invested at the Bond Yield (the “Allowable Earnings”). Earnings to be
taken into account are not determined under normal tax accounting principles. In
addition to taking into account earnings received (either actually or
constructively), receipts with respect to investments that have not been
liquidated are computed by assuming that such investments are, in essence,
converted to cash as of each computation date (as such dates are described
below). The “cash value” of investments determined in this manner is subject to
many special rules. Under many circumstances, the “market value” of an
investment may be used. The application of these rules is complex and in all
likelihood will require consultation with an expert.

     To properly plan for the eventual payment of rebate to the United States,
we suggest that you make annual calculations estimating rebate liability. The
Indenture establishes a Rebate Fund into which you may also wish to deposit
annual estimates of rebate liability so that the payment to the United States
may be made from amounts set aside. Federal tax law does not, however, require
such set asides. In any event, we strongly encourage you to make an annual
estimate of the rebate liability. The calculations can be lengthy and often
produce surprising results. Experience indicates that the calculation is far
more difficult as the period of time for which the calculation is being
performed increases.

     Phantom Income. With certain exceptions, amounts paid for administrative
costs are not treated as increasing earnings for purposes of rebate
calculations. Administrative costs that do not increase earnings are reasonable,
direct administrative costs, other than carrying costs, and generally include
brokerage commissions for the purchase of investment agreements (but only to the
extent that the commission does not exceed the present value of annual payments
equal to 0.05 percent of the weighted average amount reasonably expected to be
invested per year) and separately stated brokerage or selling commissions (but
not legal and accounting fees), record keeping, custody and similar costs and
expenses.

     Computation Dates. Each calculation of Excess Earnings should be made as of
a “Computation Date.” The Computation Date should be the same date in each
calendar year (except that the final Computation Date should be the date on
which all of the Bonds are actually retired). As indicated above, a Computation
Date is required at least every five years. The first Computation Date must be
on or before the fifth anniversary of the issuance of the Bonds. Each
Computation Date, other than the Final Computation Date, is the end of a bond
year. A bond year ends on any date within one year of the issuance of the Bonds
that you choose. In the Tax Agreement you have chosen the date immediately prior
to the anniversary date of the Dated Date of the Bonds.

C-2

--------------------------------------------------------------------------------

 

     Except as provided below, on a variable yield issue such as the Bonds,
Excess Earnings are computed for the period of time between Computation Dates
(or from the date of issue of the Bonds in the case of the first Computation
Date) by calculating Allowable Earnings based on the Bond Yield for the Bonds
for that period of time and comparing it with Actual Earnings for the same
period. Once calculated for each such period, rebate for that period cannot
change—i.e., a snapshot for that period is taken and it never changes. Prior to
the first date on which a rebate payment is required, you may choose to treat
the end of any bond year as a Computation Date for purposes of the snapshot
approach. After such date, you must consistently treat either the end of each
bond year or the end of each fifth bond year as Computation Dates, and you may
not change these Computation Dates after the first required rebate payment date.

     Bond Yield. For variable yield issues such as the Bonds, as discussed
above, Bond Yield is computed as of each Computation Date for the period from
the prior Computation Date (or from the date of issue of the Bonds in the case
of the first Computation Date) to the current Computation Date, and it is based
upon (i) the actual payments of principal and interest on the Bonds (including
amounts treated as interest) and (ii) the assumed receipt on such date of an
amount equal to the value of the outstanding Bonds. The rules for computing Bond
Yield are quite complex and an expert should be consulted.

     Generally, upon conversion of a variable yield issue to a fixed yield issue
the yield on the issue after the conversion date will be calculated under the
fixed yield rules. Certain special rules and elections apply upon such a
conversion and an expert should be consulted.

     Gross Proceeds. Gross Proceeds is defined in Article VII of the Tax
Agreement. Based upon the facts and expectations presented in the Tax Agreement,
the Gross Proceeds are all moneys and investments in the funds and accounts
(regardless of where held) held by the Trustee under the Indenture other than
the Bond Purchase Fund and the Rebate Fund. If, contrary to the expectations
described in the Tax Agreement, moneys or investments are pledged or otherwise
set aside for payment of principal of or interest on the Bonds, such amounts may
also constitute Gross Proceeds.

     Universal Cap. Gross Proceeds will cease to be allocated to the Bonds (and
will therefore be treated as if spent) if the amount of Gross Proceeds exceeds
the outstanding amount of the Bonds (the “Universal Cap”). Although special
rules are applicable in the case of discount bonds, the outstanding amount of
bonds is roughly equal to the outstanding principal amount. Generally, but not
always, the market value of investments is used to test the amount of Gross
Proceeds. The Universal Cap may cause allocations on the second anniversary of
the issue date and as of the first day of each bond year thereafter.

     Commingled Funds. Funds allocated to two or more issues, or containing
amounts that are not Gross Proceeds of the Bonds and amounts that are Gross
Proceeds of the Bonds (including, for example, parity reserve funds) in which
amounts are invested collectively without regard to source of funds must be
treated as commingled funds. Investment earnings on commingled funds must be
allocated to the Gross Proceeds of the Bonds according to a consistently applied
reasonable ratable allocation method. Such method, for example, may be based on
average daily balances. Investments in commingled funds must generally be valued
annually to properly allocate unrealized gain or loss to the Gross Proceeds of
the Bonds. This mark to market requirement will generally not apply if the
weighted average maturity of all

C-3

--------------------------------------------------------------------------------

 

investments held in the commingled fund during a particular fiscal year does not
exceed 18 months, and does not apply to commingled debt service reserve funds.

     Bona Fide Debt Service Fund Exception to the General Rule. Based upon the
information in the Tax Agreement, the Bond Fund is a bona fide debt service
fund. If the earnings in the Bond Fund in a bond year (as described above under
“Computation Dates”) is less than $100,000 in the aggregate, they will not be
subject to the rebate requirement and you may keep such earnings for that year.
If during such period earnings on these funds are $100,000 or greater, all such
earnings will be subject to rebate. However, if the average annual debt service
on the Bonds is no more than $2,500,000, you may treat these funds as satisfying
the $100,000 limitation in each year. To the extent that the Bond Fund ceases to
be a “bona fide debt service fund” as described in Section 2.2 of the Tax
Agreement, some Bond Fund moneys may be subject to the rebate requirement (if
this occurs, please call us for advice).

     Tax-Exempt Obligation Exception to the General Rule. To the extent that any
Gross Proceeds are invested in Tax-Exempt Obligations (as defined in Article VII
of the Tax Agreement), the earnings thereon would not be considered when
calculating Excess Earnings. To the extent that 100% of Gross Proceeds are
continually invested in Tax-Exempt Obligations, there would be no rebate
requirement.

     Investment of Rebate Fund and Other Funds. Investments of moneys in the
Rebate Fund and any other fund must be made in arm’s-length transactions in a
manner that does not reduce the amount to be rebated to the United States.
Investment decisions (other than the decision to invest in Tax-Exempt
Obligations to avoid rebate) must be made on the basis of normal investment
criteria of safety, yield and when the money will be needed. All interest rates
and yields must be market rates and yields. Money must not be allowed to remain
uninvested except for small amounts or for short periods of time, as provided in
Section 3.3 of the Tax Agreement. Specific rules exist for certificates of
deposit and investment agreements (including repurchase agreements) as set forth
in Section 3.3 of the Tax Agreement.

     Rebate Payments. Within 60 days after the Computation Date that is the end
of the fifth bond year and every fifth bond year thereafter, at least 90% of the
Excess Earnings and all earnings on the Excess Earnings (net of an appropriate
credit, which depends on whether unexpended Gross Proceeds continue to exist)
must be paid to the United States. Within 60 days of final payment of principal
of and interest on the Bonds to the Bondholders, all Excess Earnings and all
earnings on the Excess Earnings (net of the credit) must be paid to the United
States.
