Ladies and Gentlemen:

           We have acted as counsel to Progressive Return Fund, Inc. (the
"Acquiring Fund"), a Maryland corporation and Cornerstone Strategic Value Fund,
Inc. (the "Target Fund"), a Maryland corporation, in connection with the Merger
Agreement and Plan of Reorganization (the "Agreement") dated as of October __,
2002 between the Acquiring Fund and the Target Fund. The Agreement describes a
proposed transaction (the "Transaction") to occur on or about October __, 2002
(the "Exchange Date"), pursuant to which the Acquiring Fund will acquire
substantially all of the assets of the Target Fund in exchange for shares of
Common Stock in the Acquiring Fund (the "Acquiring Fund Shares") and the
assumption by the Acquiring Fund of all of the liabilities of the Target Fund
following which the Acquiring Fund Shares received by the Target Fund will be
distributed by the Target Fund to its shareholders in liquidation and
termination of the Target Fund. This opinion as to certain federal income tax
consequences of the Transaction is furnished to you pursuant to the terms of the
Agreement. Capitalized terms not defined herein are used herein as defined in
the Agreement.

           The Target Fund is registered under the Investment Company Act of
1940, as amended (the " 1940 Act"), as a diversified closed-end management
investment company. The Target Fund has elected to be a regulated investment
company for federal income tax purposes under Section 851 of the Internal
Revenue Code of 1986, as amended (the "Code").

           The Acquiring Fund is registered under the 1940 Act as a
non-diversified closed-end management investment company. The Acquiring Fund has
registered as a closed-end investment company under the 1940 Act. Shares of the
Acquiring Fund are redeemable at net asset value at each shareholder's option.

<PAGE>

           In rendering our opinion, we have reviewed and relied upon the
Agreement, the Proxy Statement/Prospectus and the Registration Statement
(including the items incorporated by reference therein). We have relied, without
independent verification, upon the factual statements made therein, and assume
that there will be no change in material facts disclosed therein between the
date of this letter and the date of closing of the transaction. We further
assume that the transaction will be carried out in accordance with the
Agreement:

           1. The Target Fund will transfer to the Acquiring Fund all of its
assets, and the Acquiring Fund will assume all of the liabilities of the Target
Fund, as of the Exchange Date.

           2. The fair market value of the Acquiring Fund Shares received by
each Target Fund shareholder will be equal to the fair market value of the
Target Fund shares surrendered in exchange therefor. The Target Fund
shareholders will receive no consideration other than Acquiring Fund Shares
(which may include fractional shares) in exchange for their shares of Common
Stock in the Target Fund (the "Target Fund Shares").

           3. To the knowledge of the management of the Target Fund: (i) there
is no plan or intention by any Target Fund shareholder who owns 5 % or more of
the total outstanding Target Fund Shares; and (ii) there is no plan or intention
on the part of the remaining Target Fund shareholders to sell, exchange, or
otherwise dispose of a number of Acquiring Fund Shares received in the
Transaction that would reduce the Target Fund shareholders' ownership of
Acquiring Fund Shares to a number of Acquiring Fund Shares having a value, as of
the date of the Transaction, of less than 50 percent of the value of all of the
formerly outstanding Target Fund Shares as of the same date. For purposes of
this representation, Acquiring Fund Shares or Target Fund Shares surrendered by
Target Fund shareholders as a repurchase of the Target Fund or otherwise
disposed of, where such dispositions, if any, appear to be initiated by Target
Fund shareholders in connection with or as a result of the Agreement or the
Transaction, will be treated as outstanding Target Fund Shares on the date of
the Transaction.

           4. The Acquiring Fund has no plan or intention to reacquire any of
the Acquiring Fund Shares issued in the Transaction, except for Acquiring Fund
Shares reacquired in the ordinary course of its business as a closed-end
investment company pursuant to its share repurchase plan.

                                      -2-
<PAGE>

           5. The Acquiring Fund will acquire the fair market value of all of
the net assets and gross assets held by the Target Fund immediately prior to the
Transaction and the Target Fund will cease to exist. For purposes of this
representation, (a) amounts paid by the Target Fund, out of the assets of the
Target Fund, to the Target Fund shareholders as a repurchase of Target Fund
Shares, where such repurchases, if any, appear to be initiated by Target Fund
shareholders in connection with or as a result of the Agreement or the
Transaction, and (b) amounts used to effect such repurchases and distributions
(except for regular, normal dividends declared and paid in order to ensure the
Target Fund's continued qualification as a regulated investment company and to
avoid fund-level tax) made by the Target Fund immediately preceding the transfer
will be included as assets of the Target Fund held immediately prior to the
Transaction. Further, to the best of the knowledge of the managements of each of
the Acquiring Fund and the Target Fund, this representation will remain true
even if the amounts, if any, that the Acquiring Fund pays after the Transaction
to Acquiring Fund shareholders who are former Target Fund shareholders as a
repurchase of Acquiring Fund Shares received in exchange for Target Fund Shares,
where such repurchases, if any, appear to be initiated by such shareholders in
connection with or as a result of the Agreement or the Transaction, are
considered to be assets of the Target Fund that were not transferred to
Acquiring Fund.

           6. The fair market value of the assets transferred to the Acquiring
Fund by the Target Fund will equal or exceed the sum of the liabilities to be
assumed by the Acquiring Fund.

           7. The Acquiring Fund has no plan or intention to sell or otherwise
dispose of any of the assets of the Target Fund acquired in the Transaction,
except for dispositions made in the ordinary course of its business as an
closed-end investment company (I e., dispositions made in the ordinary course of
business and independent of the Transaction).

           8. The liabilities of the Target Fund to be assumed by the Acquiring
Fund were incurred by the Target Fund in the ordinary course of its business and
are associated with the assets transferred to the Acquiring Fund. For purposes
of this paragraph, expenses of the Transaction are not treated as liabilities.

           9. All fees and expenses, including accounting expenses, portfolio
transfer taxes (if any) or other similar expenses incurred in connection with
the Reorganization will be paid by each party respectively.

           10. For federal income tax purposes, the Target Fund qualifies as a
regulated investment company, and the provisions of Sections 851 through 855 of
the Code apply to the Target Fund for its current taxable year beginning January
1, 2002 and will continue to apply to it through the Exchange Date.

           11. The Acquiring Fund intends to qualify as a regulated investment
company for the fiscal year ending December 31, 2002.

           12. The Acquiring Fund does not own, directly or indirectly, any
Target Fund Shares.

           13. There is no intercorporate indebtedness existing between the
Target Fund and the Acquiring Fund.

<PAGE>

           14. The Target Fund will distribute the Acquiring Fund Shares it
receives in the Transaction to its shareholders as provided in the Agreement.

           15. The Target Fund is not under the jurisdiction of a court in a
Title 11 or similar case within the meaning of Section 368(a)(3)(A) of the Code.

           Based on the foregoing representations and our review of the
documents and items referred to above, we are of the opinion that for federal
income tax purposes:

           (i) the transfer by the Target Fund of substantially all of its
assets to the Acquiring Fund, solely in exchange for Acquiring Fund Shares, is a
reorganization within the meaning of Section 368(a)(1)(A) of the Internal
Revenue Code of 1986, as amended (the "Code");

           (ii) no gain or loss will be recognized by the Target Fund upon the
transfer of substantially all of the Target Fund's assets to the Acquiring Fund
in exchange solely for Acquiring Fund Shares;

           (iii) no gain or loss will be recognized by the Acquiring Fund on
receipt of the assets of the Target Fund in exchange for Acquiring Fund Shares
and the assumption by the Acquiring Fund of the liabilities of the Target Fund;

           (iv) the basis of the assets of the Target Fund in the hands of the
Acquiring Fund is, in each instance, the same as the basis of those assets in
the hands of the Target Fund immediately prior to the Transaction;

           (v) the holding period of the Target Fund's assets in the hands of
the Acquiring Fund includes the holding period during which the assets were held
by the Target Fund;

           (vi) no gain or loss is recognized to the Target Fund shareholders
upon the receipt of Acquiring Fund Shares solely in exchange for the Target Fund
Shares;

           (vii) the basis of the Acquiring Fund Shares received by the Target
Fund shareholders is, in each instance, the same as the basis of the Target Fund
Shares surrendered in exchange therefor; and

           (viii) the holding period of the Acquiring Fund Shares received by
the Target Fund shareholders includes the holding period during which Target
Fund Shares surrendered and exchanged therefor were held, provided that such
shares were held as a capital asset in the hands of the Target Fund shareholders
on the Exchange Date.

           This opinion is rendered solely for the benefit of satisfying the
conditions set forth in the Agreement and is intended solely for your benefit
and may not be relied upon by any other person or for any other purpose without
our prior written consent, and we consent to the filing of this opinion with the
Securities and Exchange Commission in connection with the registration of the
Acquiring Fund's shares.

                                                          Very truly yours,

<PAGE><Page>

                                                                   EXHIBIT 10.06

                                 LOAN AGREEMENT

     This Loan Agreement (the "Agreement") is entered into as of this 25th day

                                    RECITALS

     A.    Holder wishes to lend to Borrower and Borrower wishes to borrow from

financial support beyond that contemplated under the terms of this Agreement,
nor shall Holder have any obligation to provide any technical, marketing or
other advice, or opportunities to Borrower. Holder reserves the right to provide
or refuse to provide any assistance in Holder's sole discretion.

     2.    SECURITY.

           All obligations of Borrower under this Agreement and the Note shall
be secured by the Collateral pursuant to the terms and conditions set forth in

secured party, granting Holder a security interest in the Collateral (subject
only to the security interest held by First Union National Bank, or such
financial institution replacing it as a secured party, under various loan
documents for an amount not exceeding Three Million Dollars ($3,000,000.00) in
principal, plus interest, attorneys' fees, late charges, and other costs and
expenses due and owing under the agreements between Borrower and First Union
National Bank (the "Credit Limit")). Borrower covenants and agrees to execute
and deliver the Security Agreement and such other documents as may be necessary
for the perfection and preservation of Holder's security interest in the
Collateral.

     3.    CONDITIONS PRECEDENT.

           The obligation of Holder to disburse the loan to Borrower at Closing

           Borrower represents and warrants that:

           4.1      Each company listed as Borrower is a corporation duly

where failure to be so qualified would not have a material adverse effect on
Borrower's business.

                                        2
<Page>

           4.2      The execution, delivery and performance of this Agreement
and any instrument or agreement required of Borrower hereunder are within
Borrower's powers, have been duly authorized and are not in conflict with the
terms of the articles of incorporation or bylaws of Borrower, or any instrument
or agreement to which Borrower is a party or by which Borrower is bound or
affected.

           4.3      No approval, consent, exemption or other action by, or
notice to or filing with, any governmental authority is necessary in connection
with the execution, delivery, performance, or enforcement of this Agreement or
any instrument or agreement required hereunder, except as may have been obtained
and certified copies of which have been delivered to Holder.

           4.4      There is no law, rule or regulation, nor is there any

Borrower hereunder.

           4.5      This Agreement is a legal, valid and binding agreement of
Borrower, enforceable against Borrower in accordance with its terms, and any
instrument or agreement required to Borrower hereunder, when executed and
delivered, and will be similarly legal, valid, binding and enforceable, except
as enforcement may be limited by bankruptcy, insolvency or other similar laws
affecting the enforcement of creditors' rights generally, and subject to rules
of law governing specific performance, injunctive relief and other equitable
remedies.

           4.6      Borrower has good and marketable title to the Collateral
which is subject to the Security Agreement, free and clear of all clouds to
title and of all security interests, liens, encumbrances or rights of others,

Schedule A attached hereto.

           4.7      Borrower represent that as of the Closing that the loan by
Holder hereunder shall be prior and superior to any other indebtedness of
Borrower other than the security interest held by First Union National Bank
("Bank"). Except for the due filing or recording of financing statements on Form
UCC-1 pursuant to the Security Agreement, no further action is necessary in
order to establish and perfect Holder's security interest in or lien on all
Collateral subject only to the security interest of the Bank.

           4.8      There are no suits, proceedings, claim or disputes pending
or, to the knowledge of Borrower, threatened against or affecting Borrower or
its property, the adverse determination of which might affect Borrower's
financial condition or operations or impair Borrower's ability to perform their
obligations hereunder or under any instrument or agreement required hereunder.

           4.9      Borrower has provided to Holder preliminary drafts of
financial statements of Borrower for fiscal year end 1997 and 1998 (June 1997
and June 1998), and financial

<Page>

statement and balance sheet, and unaudited financial statements for the period
of July through September 1998 (collectively the "Financial Statements").
Borrower represents that the Financial Statements were prepared in accordance
with generally accepted accounting principles and fairly represents Borrower's
financial condition and results of operations as of the date thereof.

     5.    COVENANTS.

           Borrower covenants and agrees that so long as any amount is due
Holder from Borrower upon the Note or otherwise:

           5.1      Borrower will promptly notify Holder of any "Event of
Default" (the term "Events of Default" being as defined in the form of Security
Agreement attached hereto as Exhibit B) or any event which, upon a lapse of time
or notice or both, would become an Event of Default.

           5.2      Borrower will deliver to Holder as soon as available, but no

generally accepted accounting principles and certified by independent certified
public accountants reasonably acceptable to Holder.

           5.3      Borrower will deliver to Holder as soon as available, but no

unaudited financial statements as of the close of such quarter, certified by a
responsible officer of Borrower as being complete and correct and fairly
representing Borrower's financial condition and results of operations.

           5.4      Borrower will deliver to Holder at the Closing a written
budget for each fiscal year occurring during the term of this Agreement and,
when available but in no event later than ninety (90) days after each fiscal

           5.5      Borrower will deliver to Holder such additional information
relating to Borrower's financial condition and results of operations as Holder
may reasonably request from time to time.

           5.6      Borrower agrees that proceeds from the loan made hereunder
shall be used for the purpose of opening new offices, hiring new employees,
producing training materials, purchasing and selling Holder's products, and
repayment of any debt due and owed by Borrower to Holder or to First Union
National Bank. In no event shall proceeds from the loan be used for any of the
following purposes without prior written consent of Holder:

business;

                    (b)   Acquisition of property, plant or equipment except (i)
acquisitions in the ordinary course of business each in the amount of less than

                                        4
<Page>

related to the primary purpose of the loan.

                    (c)   Repayment of any debt, including shareholder notes,
other than as explicitly allowed in this section;

                    (d)   Bonuses, extraordinary salary increases or deferred
compensation for officers or directors of Borrower; or

                    (e)   Trade shows, advertising, production of marketing
materials or brochures.

           5.7      Borrower will promptly notify Holder of any material claim,
action, suit or proceeding against Borrower or its assets.

           5.8      Borrower will maintain current capital, including
subordinated debt, of at least One Million Five Hundred Thousand Dollars
($1,500,000.00), plus equity existing as of the date of this Agreement.

           5.9      Borrower will maintain a ratio of current assets to current
liabilities (excluding the current portion of any subordinated indebtedness), in
each case determined in accordance with generally accepted accounting principles
of at least 1.0 to 1.0.

           5.10     Borrower will maintain a ratio of total liabilities to
permanent capital of no greater than 10 to 1.0

           5.11     Borrower will not borrow, from First Union National Bank or
otherwise, additional funds such that at any time there is due and owing from
Borrower to First Union National Bank an amount in excess of the Credit Limit or
further encumber any of the assets constituting Collateral under the Security
Agreement without the prior written consent of Holder.

     6.    EVENTS OF DEFAULT.

           The occurrence of any of the "Events of Default" as defined in the
Security Agreement, at the option of Holder, shall make the remaining unpaid
balance of the Note immediately due and payable.

     7.    CONFIDENTIAL INFORMATION.

           Each of Holder and Borrower agrees not to use any Confidential
Information of the other party disclosed to it, for its own use or use by any
other person or for any purposes except to carry out, perform and enforce its
obligations under agreements between Holder and Borrower, and not to disclose
any such Confidential Information except to employees (or

                                        5
<Page>

consultants subject to confidentiality provisions similar to this Section 7) who
are required to have such information in order to carry out, perform or enforce
such obligations. Borrower and Holder will take all reasonable measures to
protect the secrecy and avoid disclosure or use of Confidential Information in
order to prevent it from entering the public domain or possession of persons
other than those persons authorized hereunder to have any such information,
which measures shall include, without limitation, the highest degree of care
that each utilizes to protect its own confidential information of a similar
nature. Either party shall notify the affected party promptly in writing of any
misuse or misappropriation of Confidential Information which may come to such
party's attention.

           For purposes of this section, "Confidential Information" means (i)
the terms of this Agreement, the Secured Promissory Note and Security Agreement
and accompanying transactions (provided, however, that said Agreement, Secured
Promissory Note and Security Agreement may be disclosed to a party having a
secured position with Borrower prior to that of Holder), as well as (ii) any
proprietary information, technical data, trade secrets or know-how, including,
without limitation, research, product plans, products, services, customers,
markets, software, developments, inventions, processes, formulae, technology,
designs, drawings, engineering, hardware configuration information, marketing,
finances or other business or technological information disclosed by either
party to the other either directly or indirectly. "Confidential Information" of
a disclosing party does not include any information which: (i) is known to the
receiving party at the time of disclosure; (ii) has become publicly known
through no wrongful act of the receiving party; (iii) has been rightfully
received by the receiving party from a third party without restriction on
disclosure and without breach of any agreement with the disclosing party; (iv)
has been independently developed by the receiving party as evidenced by
appropriate documentation; (v) has been approved for release by written
authorization executed by an authorized officer of the disclosing party; (vi) is
required to be disclosed by the receiving party pursuant to a requirement of
law; or (vii) (A) is not provided in writing or on magnetic media, or (B) if
provided orally, is not confirmed in writing to be confidential within fifteen
(15) days after disclosure. Should Borrower wish to disclose the specific terms
of this Agreement or the other Loan Documents to a potential investor or
investors, it shall first obtain written consent to such disclosure from Holder,
which consent shall not be unreasonably withheld with respect to bona fide
potential investors.

           Each party acknowledges that the other's Confidential Information is
unique property of extreme value to the other party, and that unauthorized use
or disclosure thereof would cause the other party irreparable harm that could
not be compensated by monetary damages. Accordingly, each party agrees that the
other will be entitle to injunctive and preliminary relief to remedy any actual
or threatened unauthorized use or disclosure of the other party's Confidential
Information.

           Nothing in this Section 7 is intended to supersede any existing
agreement between the parties under which confidential technical or market
information has or may be given by one party to the other. As to matters not
covered by such existing agreements, this Section 7 shall

                                        6
<Page>

control in the absence of any specific agreement to the contrary.

                                             Attention: Treasurer

                    8.2      This Agreement, together with the covenants and
warranties contained in it, shall bind and inure to the benefit of the parties
hereto and their respective successors and assigns, provided, however, that
Borrower may not assign this Agreement or any of the rights of Borrower
hereunder without the prior written consent of Holder.

                    8.3      No delay or omission by Holder to exercise any
right under this Agreement shall impair any such right, nor shall it be
construed as a waiver thereof. No waiver of any single breach or default under
this Agreement shall be deemed a waiver of any other breach or default. Any
waiver, consent or approval under this Agreement must be in writing to be
effective.

                    8.4      Borrower and Holder each shall bear its own costs
and expenses incurred in connection with the preparation and administration of
this Agreement and any instrument or agreement required hereunder. Borrower
agrees to pay all costs, expenses and

attorneys' fees reasonably incurred by Holder in connection with the enforcement
of this Agreement.

                    8.5      This Agreement, and any agreement, document or
instrument attached hereto or referred to herein, integrate all the terms and
conditions mentioned herein or incidental hereto, and supersede all oral
negotiations and prior writings in respect to the subject matter hereof. In the
event of any conflict between the terms, conditions and provisions of this
Agreement and any such agreement, document or instrument, the terms, conditions
and provisions of this Agreement shall prevail. This Agreement may be executed
in counterparts, and each counterpart shall be deemed an original instrument,
but together shall constitute one and the same instrument. Additionally, any
signatures sent by facsimile shall be deemed to be originals and shall have all
of the same force and effect and import as an original signature, regardless of
whether or not the parties shall or shall not later receive one or more such
original signature.

                    8.6      This Agreement shall be construed in accordance
with the laws of the State of California (excluding rules regarding conflicts of
law). The parties hereby submit to the personal jurisdiction of and venue in the
Superior Court of the State of California, County of Marin, and the United
States District Court for the Northern District of California in San Francisco.

                    8.7      The illegality or unenforceability of any provision
of this Agreement or any instrument or agreement required hereunder shall not in
any way affect or impair the legality or enforceability of the remaining
provisions of this Agreement or any instrument or agreement required hereunder.

                    8.8      In addition to any rights and remedies of Holder
provided by law, Holder shall have the right, without prior notice to Borrower,
any such notice being expressly waived by Borrower to the extent permitted by
applicable law, upon the occurrence and during the continuance of an Event of
Default, to set-off and apply against any indebtedness, whether matured or
unmatured, of Borrower to Holder, any amount owing from Holder to Borrower. The
aforesaid right of set-off may be exercised by Holder against Borrower or
against any trustee in bankruptcy, debtor-in-possession, assignee for the
benefit of creditors, receiver or execution, judgment or attachment creditor of
Borrower or against anyone else claiming through or against Borrower or such
trustee in bankruptcy, debtor-in-possession, assignee for the benefit of
creditors, receiver, or execution, judgment or attachment creditor,
notwithstanding the fact that such right of set-off shall not have been
exercised by Holder prior to the occurrence of an Event of Default. Holder
agrees promptly to notify Borrower after any such set-off and application by
Holder, PROVIDED that the failure to give such notice shall not affect the
validity of such set-off and application.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement by
their duly authorized officers as of the day and year first above written.

           4.       BORROWER'S COVENANTS.

                    Borrower agrees and covenants that:

                    4.1   FURTHER ENCUMBRANCES.

                          Except to the extent of the Credit Limit (as that term
is defined in the Loan Agreement) provided to Borrower by First Union National
Bank which holds a security interest with Borrower as of the date of this
Security Agreement, Borrower shall not, without Holder's consent (which consent
shall not be unreasonably withheld) grant a security interest in any of the
Collateral or execute any financing statements covering any of the Collateral in
favor of any person until Borrower's Obligations secured under this Security
Agreement shall have been repaid and performed in full. Notwithstanding the
foregoing, Borrower may allow a financial institution to replace First Union
National Bank and obtain, in place of said bank, the secured position held by
First Union National Bank as of the date of this Agreement to the extent of the
Credit Limit.

                    4.2   USE OF COLLATERAL.

                          The Collateral will not be used for any unlawful

                    4.3   INDEMNIFICATION.

                          Borrower shall indemnify Holder against all losses,

                                       23
<Page>

the Collateral and shall execute and deliver such other documents as Holder
deems necessary to create, perfect and continue the security interest in the
Collateral contemplated hereby, including, but not limited, to the forms and
documents attached hereto as Attachment A.

                    4.5   COLLECTION OF ACCOUNTS.

                          Borrower shall collect with diligence all of its
Receivables and proceeds of Inventory, Equipment and other personal property.

                    4.6   RECORDS.

                          Borrower shall prepare and keep in accordance with

Holder, shall, from time to time, prepare and deliver a complete and accurate
schedule of all the Collateral, in such detail as Holder may reasonably request.

                    4.7   INSPECTION OF BORROWER'S BOOKS.

                          Borrower shall permit Holder and its designees at
reasonable times and from time to time to inspect Borrower's books, records and
properties and to audit and to make copies of extracts from such books and
records.

                    4.8   FEES AND COSTS.

                          Upon any Event of Default, Borrower shall pay all
expenses, including attorneys' fees, incurred by Holder in the preservation,
realization, enforcement or exercise of any of Holder's rights under this
Security Agreement.

           5.       EVENTS OF DEFAULT.

                    The following are an Event of Default under this Security
Agreement.

                    5.1   The occurrence of any Event of Default, as defined in
the Note;

                    5.2   The failure to pay an amount due Holder when and as
due, provided however, that, to the extent amounts are past due from Borrower to
Holder for more than thirty (30) days as of the date of this Security Agreement,
then as to that amount such failure to pay when due shall not constitute a
default under this Section 5.2 until March 5, 1999.

                                       24
<Page>

                    5.3   To the extent not otherwise deemed a default under
Sections 5.1 or 5.2 herein, the breach or default by Borrower of any agreement
Borrower has with any party holding a security interest in any property of
Borrower, provided, however, that, to the extent Borrower is in breach or
default of any agreement with First Union National Bank as of the date of this
Agreement, this Section 5.3 shall not apply to the limited extent of that
specific breach or default with said bank until March 5, 1999.

           6.       REMEDIES ON DEFAULT.

                    Upon the occurrence of an Event of Default, provided that
payment in full has not been made, the Holder shall have all rights, privileges,
powers and remedies provided by law, which rights, privileges, powers, and
remedies shall be cumulative, and no single or partial exercise of any of them
shall preclude the further or other exercise of the same or any of them. By way
of example and not by way of limitation, Holder may, pursuant to this Section 6,
exercise any one or all of the remedies hereinafter set forth:

                    6.1   PAYMENT UNDER NOTE; ACCOUNT BALANCE.

                          The Holder may by notice under Section 12 declare the
aggregate unpaid principal balance of the Note and all other amounts owing to
Holder from Borrower, together with all unpaid accrued interest thereon, to be
immediately due and payable to the Holder.

                    6.2   POSSESSION OF COLLATERAL.

                          (a)     The Holder may take possession of all
Collateral covered hereby (which Collateral Borrower will assemble and make
available to Holder) using the employees, facilities, equipment and other
property of Borrower to do so, all at Borrower's expense and without
compensation to Borrower.

                          (b)     If and when requested by Holder, Borrower
shall upon any Event of Default prepare and deliver to Holder assignments in
writing of all Collateral and related accounts, instruments, documents and other
evidences thereof.

                    6.3   USE, OPERATION AND SALE OF COLLATERAL BY HOLDER.

                          The Holder may use, operate, consume and sell the
Collateral in its possession as appropriate for the purpose of performing
Borrower's obligations with respect thereto. Borrower and Holder agree that
public or private sales, for cash or on credit, to a wholesaler or retailer or
use of Collateral of the types subject to this Security Agreement, or at public
auction, are all commercially reasonable since differences in the sales prices
generally realized in the different kinds of sale are ordinarily offset by the
differences in the costs and credit risks of such sales.

                                       25

           7.       PAYMENTS AFTER AN EVENT OF DEFAULT.

                    All payments received and amounts realized by the Holder
pursuant to Section 6, including all such payments and amounts received after
the Holder has declared pursuant to Section 6.1 the entire unpaid principal and
interest amount of the Note to be due and payable, as well as all payments or
amounts then held or thereafter received by the Holder as part of the Collateral
while an Event of Default shall be continuing, shall be promptly applied and
distributed by the Holder in the following order of priority:

                          (a)     First, to the payment of all amounts claimed
due by a person holding a secured interest in the Collateral prior to the
interest of Holder, and all reasonable costs and expenses, including legal
expenses and attorneys fees, incurred or made hereunder by the Holder, including
any such costs and expenses of foreclosure or suit, if any, and of any sale or
the exercise of any other remedy under Section 6, and of all taxes, assessments
or liens superior to the lien granted under this Security Agreement, except any
taxes, assessments or other superior lien subject to which any said sale under
Section 6 hereof may have been made;

                          (b)     Second, to the payment of all amounts then
owned by Borrower to Holder, excepting the amount then owing or unpaid on the
Note;

                          (c)     Third, to the payment of the amount then owing
or unpaid on the Note, with application to be made first to the unpaid interest
thereon and second, to the unpaid principal thereof, such application to be made
upon presentation of the Note and the notation thereon of the payment, if
partially paid, or the surrender and cancellation thereof, if fully paid; and

                          (d)     Fourth, to the payment of the balance or
surplus, if any, to Borrower, its successors and assigns, or to any other party
who may be lawfully entitled to receive the same.

           8.       POWER OF ATTORNEY.

                    Borrower hereby appoints Holder the attorney-in-fact of
Borrower to prepare, sign and file or record, for Borrower in Borrower's names,
any financing statements, applications for registration and like papers and to
take any other action deemed by Holder necessary or desirable in order to
perfect the security interest of Holder hereunder, and to perform any obligation
of Holder hereunder at Borrower's expense, but without obligation to do so.
Holder agrees to provide prior written notice to Borrower of any such action
taken as attorney-in-fact of Borrower, together with copies of any financing
statements, applications or other papers executed in such capacity by Holder.

                                       26

           9.       HOLDER'S RIGHT TO CURE: REIMBURSEMENT.

                    In the event Borrower should fail to do any act as herein
provided, Holder may, but without obligation to do so, without notice or release
