B. USE OF PROCEEDS.

                               SECURITY FOR LOANS

     All funds advanced or loaned to Maker by Lender including all amounts
evidenced by any and all Secured Promissory Notes as having been loaned or
advanced by Lender to Maker are secured by collateral pursuant to a security
agreement of even date herewith for the benefit of Lender (the "SECURITY
AGREEMENT"), and a limited guarantee. Such instruments and documents, together

herein as the "SECURITY DOCUMENTS". In the event of any inconsistency between
the terms of this Agreement, any Secured Promissory Note and any of the Security
Documents, the terms of this Agreement shall control; however, this provision
shall not be deemed to limit, abrogate, restrict or impair any provision in any

                          CONVERSION OF DEBT INTO STOCK

A. CONVERSION RIGHTS.

     The Lender shall have the option and may, in the sole exercise of its
discretion, elect to convert all or a portion of the outstanding balance of all
loans and advances made by Lender to Maker under this Agreement, the Secured
Promissory Notes and any other instrument or transaction between Lender and
<PAGE>
Line of Credit Agreement between Dyna-Cam and Aztore
Effective Date April 30, 2001; page 8 of 17

Maker into such shares of Maker's Series A Preferred stock, at $1.00 per share
(the "CONVERSION PRICE"). In the event that Lender elects to exercise its option
to convert its debt into such securities, Lender shall deliver a notice of its
election to convert (the "CONVERSION NOTICE") to Maker at the address set forth
herein within ten business days from the receipt of the payoff of all Notes
hereunder and a Termination Notice. Within seven days following the date of the
Conversion Notice, Maker shall issue to Lender such Conversion Shares that shall
be equal to the aggregate dollar amount of principal and interest elected for
conversion divided by the Conversion Price as may be adjusted from time to time
as provided herein, and shall deliver to Lender a certificate evidencing the
ownership by Lender or its nominee of such securities of Maker. Lender or its
nominee, which shall be entitled to receive securities of Maker upon conversion
under this Section, shall be treated for all purposes as having become the
record holder or holders of such securities such time; provided, however, that
no such surrender on any date when the stock transfer books of Maker shall be
closed shall be effective to constitute such conversion as the record holder or
holders of such securities on such date, but such surrender shall be effective
to constitute the person or persons entitled to receive such securities as the
record holder or holders thereof for all purposes at the close of business on
the next succeeding day on which such stock transfer books are open. In
addition, in the event that Maker issues any warrants to purchase securities to
any agents for the seller of or finders of purchasers for its Conversion Shares
then Maker will issue to Lender, upon conversion, an equal percentage of
warrants related to the amount of debt converted by Maker.

B. TERM OF THE CONVERSION RIGHTS.

     1. Partial Payment/Partial Conversion. If Maker, at any time, tenders
payment of an amount which is less than the full amount due to Lender (a
"PARTIAL PAYMENT"), then Lender may exercise its right to convert the amount of
debt represented by such Partial Payment for a period of ten business days after
any such Partial Payment has been received by Lender by serving Maker with a
Conversion Notice stating the portion of the debt for which Maker has tendered
Partial Payment plus any additional amounts due and owing from Maker to Lender
which Lender is electing to convert. In the event that Lender does not timely
serve Maker with such a Conversion Notice, the Partial Payment shall be deemed
accepted, the aggregate amount of the debt due and owing to Lender by Maker
shall be reduced by the amount of such Partial Payment and the portion of
Lender's conversion rights as would relate to the amount of debt reduced by such
partial Payment shall terminate. All remaining conversions rights of Lender (the
right to convert the remaining balance of the debt due to Lender) shall be
unaffected by such Partial Payment.

     2. After Termination Date. The conversion rights granted herein to Lender
shall continue and be in full force and effect and Lender may exercise all or a
portion thereof until 10 business days after the occurrence of the Termination
Date. In the event that Maker tenders payment to Lender of all amounts due and
owing under this Agreement and/or each of executed Secured Promissory Notes or
any of the other Loan Documents ("FULL PAYMENT"), Lender may elect to convert
all or a portion of the amount of the debt for which Maker has tendered payment
by serving Maker with a Conversion Notice as set forth above. In the event that
Lender does not timely serve Maker with such a Conversion Notice, the Full
Payment shall be deemed accepted, the aggregate amount of the debt due and owing
to Lender by Maker shall be reduced by the amount of such Full Payment and the
all of Lender's conversion rights shall terminate.

                            LENDER'S AND AGENT'S FEES

     As further consideration and inducement for Lender to provide and hold the
Line of Credit available to Maker, Maker will issue to Lender within ten (10)
days of the first Note advance Sixty Thousand (60,000) shares of Series A
Preferred Stock.

     As further consideration for Lender's Loans under this Agreement, the
Series A Preferred shares in Section Eight shall also be additional interest. In
the event the Line of Credit is extended past October 31, 2001, there shall be
no additional interest or commitment fee payable in stock or otherwise.

Lender. No single or partial exercise of any power hereunder or under any
Security Document securing this Agreement and the Secured Promissory Notes or
any guaranty shall preclude other or further exercise of such power or the
exercise of any other right, remedy or power. The Lender, its nominee and/or the
holder of any of the Secured Promissory Notes shall at all times have the right
to proceed against any portion of the security in such order and in such manner
as the holder may elect, without waiving any rights with respect to any other
security. Neither (i) the acceptance by Lender, its nominee or the holder of any
of the Secured Promissory Notes of any payment in an amount less than payment in
full of the amount due and payable at the time of such payment, nor (ii) any
delay or omission on the part of the holder hereof in exercising any right,
remedy or power hereunder, shall operate as a waiver by the holder of the right
to exercise any right, remedy or power at the time or at any subsequent time, or
nullify any prior exercise of a right, remedy or power.

     Maker acknowledges and agrees that it is impractical and extremely
difficult to fix in advance the actual damages incurred by Lender, its nominee
and/or the holder of any of the Secured Promissory Notes if the required
payments are not made at Loan Maturity, due to the fact that (i) interest rates
and administrative costs fluctuate, (ii) it is impossible to predict how long a
default will continue, and (iii) the economic cost of ascertaining actual
damages in each instance of default would be excessive in relation to the actual
damages sustained. Therefore, Maker agrees to pay to Lender, its nominee and/or
the holder of any of the Secured Promissory Notes a late charge equal to eight
percent (8%) of the aggregate amount of principal plus interest due and owing at
Loan Maturity on the date that is thirty days after Loan Maturity if all amounts
due and owing to Lender, its nominee and/or any holder of any Secured Promissory
Note under this Agreement and all of the Secured Promissory Notes are not paid
in full at Loan Maturity. Maker further agrees to pay to Lender, its nominee
and/or the holder of any of the Secured Promissory Notes an additional late
charge equal to five percent (5%) of the aggregate amount of principal plus
interest due and owing at Loan Maturity on each successive thirtieth day
following Loan Maturity if all amounts due and owing to Lender under this
Agreement and all of the Secured Promissory Notes are not paid in full prior to
that date. Said late charges are intended as liquidated damages in lieu of
actual damages and not as a penalty. Maker agrees that said late charge
represents a fair and reasonable estimate of the average compensation for the
actual economic loss sustained because of a default in payment. All late charges
shall be due and payable, without further notice, on each successive thirty day
anniversary of the Loan Maturity. Late charges are in addition to any interest
charged at the Default Rate. However, in the event that applicable law may limit
the amount of late charges or the aggregate amount of late charges plus interest
that may be charged under this Agreement and the Secured Promissory Notes, such
late charges shall be at the highest rate allowed by applicable law.

     Notwithstanding the foregoing, the Lender, its nominee and/or any holder of
any Secured Promissory Note shall not be obligated to accept any delinquent
payment, nor shall acceptance of any delinquent payment or any late charges
prejudice Lender's, its nominee's or any holder's right to collect any other
amounts under this Agreement or any Secured Promissory Note, to declare a
default under or to accelerate this Agreement or any of the Secured Promissory
Note in the event of any subsequent Event of Default or to exercise any other
rights or remedies provided herein or by law. Acceptance of any delinquent
payment without the applicable late charge shall not be deemed a waiver of the
<PAGE>
Line of Credit Agreement between Dyna-Cam and Aztore
Effective Date April 30, 2001; page 12 of 17

right to collect that or any subsequent late charge. Acceptance of late charge
and/or default interest payments will be made "without prejudice" and with
explicit reservation of all rights - this notification to that effect being
intended in lieu of specific notification being set out on a check or other
instrument by which a payment may be tendered and regardless of what notations
on Maker's part may accompany any tendered payment. Specifically this means that
partial payment of amounts due and payable does not, and will not, accomplish a
reinstatement of this Agreement or any Secured Promissory Note, unless Maker and
Lender have a specific written understanding to allow reinstatement on that
basis. Such payments will simply reduce the accelerated balance owing. Any such
payment, if accepted, will be retained without prejudice to Maker's right to
proceed.

     All payments on this Agreement and any of the Secured Promissory Notes
shall be applied first to late charges and any costs, added charges or advances
made by Lender, its nominee or any holder of any of the Secured Promissory Notes
under the terms of any of the Security Documents, then to discharge all interest
including Default Interest due on the unpaid principal balance hereof, and the
remainder shall be applied to the reduction of the principal balance.

     Maker (i) waives all applicable exemption rights, whether under the state
constitution, homestead laws or otherwise, (ii) waives diligence, presentment,
protest and demand and also notice of protest of demand, of nonpayment, of
dishonor and of maturity and also recourse to suretyship defenses generally,
marshaling of assets, laches, estoppel and equitable defenses generally, and
(iii) waives offset rights against the debt evidenced by this Note.

     Maker agrees to pay all costs of collection, including reasonable
attorney's fees and all costs of suit, in the Event of Default hereunder.

                                 SECTION ELEVEN
                           AMENDMENT AND MODIFICATION

     This Agreement and the Secured Promissory Notes may not be amended,
modified or changed, nor shall any waiver of any provision hereof be effective,
except only by an instrument in writing and signed by the party against whom
enforcement of any waiver, amendment, change, modification or discharge is
sought; provided, however, that this paragraph shall in no way be a limitation
on the provisions of the consents and waivers set forth above.

                                 SECTION TWELVE
                  SEVERABILITY, ENFORCEABILITY AND CONSTRUCTION

     Each provision of this Agreement is intended to be severable. Maker and
Lender further intend and believe that each provision in this Agreement and each
of the Secured Promissory Notes complies with all applicable local, state and
federal laws and court decisions. However, if any provision or provisions in
this Agreement or any of the Secured Promissory Notes is or are found by a court
of law to be in violation of an applicable local, state or federal ordinance,
statute, law, administrative or judicial decision, or public policy, and if such
court should declare such portion or provision(s) of this Agreement or any
<PAGE>
Line of Credit Agreement between Dyna-Cam and Aztore
Effective Date April 30, 2001; page 13 of 17

Secured Promissory Note to be illegal, invalid, unlawful, void or unenforceable
as written, then it is the intent of Maker that such portion, provision(s) shall
be given full force and effect to the fullest possible extent that they are
legal, valid and enforceable, that the remainder of this Agreement and such
Notes shall be construed as if such illegal, invalid, unlawful, void or
unenforceable portion, provision(s) are not contained herein, and that the
rights, obligations and interests of the Maker and the holder hereof under the
remainder of this Agreement and such Notes shall continue in full force and
effect.

                                SECTION THIRTEEN
                                 ADDITIONAL SUMS

     All fees, additional interest, charges, points, loan origination fees,
goods, things in action or any other sums or things of value, including any
compensating balance requirements or other contractual obligations
(collectively, the "ADDITIONAL SUMS") paid by Maker to Lender, whether pursuant
to this Agreement or any Secured Promissory Note or otherwise with respect to
the indebtedness evidenced hereby, or with respect to the Security Agreement
securing this Agreement and the Secured Promissory Notes, or any other Security
Document, which, under the law of the State of Arizona may be deemed to be
interest with respect to such indebtedness, shall, for the purpose of any laws
of the State of Arizona which may limit the maximum rate of interest to be
charged with respect to such indebtedness, be payable by Maker as, and shall be
deemed to be, additional interest, and for such purposes only, the agreed upon
and contracted for rate of interest shall be the sum of the Stated Rate or the
Default Rate, as applicable, plus the rate of interest resulting from the
Additional Sums being considered as interest. Maker understands and believes
that this transaction complies with the usury laws of Arizona; however, if any
interest or other charges are ever deemed to exceed the maximum amount permitted
by law, then: (i) the amount of interest or charges payable hereunder by Maker
shall be reduced to the maximum amount permitted by law; and (ii) any excess
amount previously collected from Maker which exceeded the maximum amount
permitted by law will be credited against the outstanding principal
indebtedness. If the principal indebtedness has already been paid, the excess
amount paid will be refunded to Maker. If this paragraph becomes operative, the
total unpaid balance shall, at the option of Payee, become immediately due and
payable and shall bear interest at a maximum rate then permitted by the
applicable usury laws until all the then obligations of this Note, as modified
by this paragraph, are paid and performed in full. The acceleration provided in
this paragraph may not be avoided by Maker and all parties liable to Payee on
the Note, waiving any and all usury claims and defenses they then have.

                                SECTION FOURTEEN
                               TIME OF THE ESSENCE

     Time is of the essence of this Agreement.

                                 SECTION FIFTEEN
                      GOVERNING LAW, JURISDICTION AND VENUE

     The enforcement, performance, discharge, lack of performance and formation
of this Agreement shall be governed by, and construed and enforced in accordance
<PAGE>
Line of Credit Agreement between Dyna-Cam and Aztore
Effective Date April 30, 2001; page 14 of 17

with, the law of the State of Arizona, regardless of any applicable
conflict-of-law rules to the contrary.

     The Maker and Lender also hereby:

     (A) irrevocably submit to the jurisdiction of the Superior Court of
Maricopa County, State of Arizona, or any successor to said court, and to the
jurisdiction of the United States District Court for the District of Arizona, or
any successor to said court (hereinafter referred to as the "ARIZONA COURTS")
for purposes of any suit, action or other proceeding which relates to the
transactions contemplated in this Agreement;

     (B) to the extent permitted by applicable law, waive and agree not to
assert by way of motion, as a defense or otherwise in any such suit, action or
proceeding, any claim that they are not personally subject to the jurisdiction
of the Arizona Courts; that the suit, action or proceeding is brought in an
inconvenient forum; that the venue of the suit, action or proceeding is
improper; or that this Agreement or any transaction provided for herein may not
be enforced in or by the Arizona Courts; and

     (C) agree not to seek, and hereby waive, any collateral review by any other
court, which may be called upon to enforce the judgment or any of the Arizona
Courts, of the merits of any such suit, action or proceeding or the jurisdiction
of said Arizona Court.

                                 SECTION SIXTEEN
                               ADDITIONAL ACTIONS

     Each party hereto agrees to do all acts and things and to make, execute,
and deliver such written instruments and documents as shall from time to time be
reasonably required to carry out the terms and provisions of this Agreement.

                                 ATTORNEYS' FEES

     All attorneys' fees and costs of Lender related to the costs for the
preparation of this Agreement and any of the other Loan Documents shall be paid
by the Lender. However, in the event of any claim, controversy or dispute
arising out of or relating to this Agreement, or the breach thereof, the
prevailing party shall be entitled to recover reasonable attorneys' fees
incurred in connection with any court proceeding set by the court sitting
without a jury.

                                SECTION EIGHTEEN
                               REMEDIES CUMULATIVE

          (N) Maintain casualty insurance coverage on the Collateral in such
amounts and of such types as may be requested by Secured Party, and in any
event, as are ordinarily carried by similar businesses; and, in the case of all
policies insuring property in which Debtor shall have a security interest of any
kind whatsoever, all such insurance policies shall provide that the proceeds
thereof shall be payable to Lender as the loss payee. All said policies or
certificates thereof, including all endorsements thereof and those required
hereunder, shall be deposited with Secured Party; and such policies shall
contain provisions that no such insurance may be canceled or decreased without
thirty (30) days prior written notice to Secured Party; and in the event of
acquisition of additional insurable Collateral, Debtor shall cause such
insurance coverage to be increased or amended in such manner and to such extent
as prudent business judgment would dictate. If Debtor shall at any time or times
hereafter fail to obtain and/or maintain any of the policies of insurance
required herein, or fail to pay any premium in whole or in part relating to any
such policies, Secured Party may, but shall not be obligated to obtain and/or
cause to maintained insurance coverage with respect to the Collateral,
including, at Secured Party's option, the coverage provided by all or any of the
policies of Debtor and pay all or any part of the premium, therefor, without
waiving any Event of Default by Debtor, and any sums so disbursed by Secured
Party shall be additional Obligations of Debtor to Secured Party payable on
demand. Secured Party shall have the right to settle and compromise any and all
claims under any of the policies required to be maintained by Debtor hereunder
and Debtor hereby appoints Secured Party as its attorney-in-fact, with power to
demand, receive and receipt for all monies payable thereunder, to execute in the
name of Debtor or Secured Party or both any proof of loss, notice, draft or
other instruments in connection with such policies or any loss thereunder and
generally to do and perform any and all acts as Debtor, but for this
appointment, might or could perform; and

          (O) Permit Secured Party, through its authorized attorneys,
accountants and representatives, to inspect and examine the Collateral and the
books, accounts, records, ledgers and assets of every kind and description of
Borrower with respect thereto at all reasonable times.

     3. WAIVER. Debtor hereby waives any and all rights available to it as a
surety by operation of law or otherwise, including, without limitation, its
rights under A.R.S.ss.ss.12-1641 et. seq., Arizona Rule of --- ---- Civil
Procedure 17 (f), and other laws and regulations of similar import.

     4. ATTORNEY IN FACT. Debtor does hereby authorize and appoint Secured Party
as its attorney-in-fact, with full power of substitution to execute all
documents and to do all things deemed necessary or appropriate by Secured Party
to discharge Debtor's obligations under or with respect to the Collateral and/or
preserve or reenforce its rights thereunder or with respect thereto (but without
obligation to do so) including, without limitation, the right to file financing
statements. All sums expended by Secured Party for the above purposes shall be
deemed to be part of the Obligations, shall be payable to Secured Party
immediately (without demand), together with interest thereon at a rate equal to
eight (8) percentage points above the "prime rate" of interest charged by Wells
Fargo Bank to large business borrowers in Arizona, as announced by that bank
from time to time, per annum (the "DEFAULT RATE"), however, in the event that
applicable law may limit the amount of interest that may be charged under this
Agreement and the Secured Promissory Notes, such Default Rate shall be at the
<PAGE>
Security Agreement dated April 30, 2001
Page 7 of 14
--------------------------------------------------------------------------------

highest rate allowed by applicable law, from the date the expenditure was
incurred until paid, and shall be secured by all security for the payment and
performance of the Obligations.

     5. EVENTS OF DEFAULT; REMEDIES.

          (A) The occurrence of any of the following events shall constitute an
Event of Default: (i) if there occurs a default or violation in the full and
timely performance of any Obligation owing to Secured Party hereunder or under
the Loan Documents; (ii) if any representation, warranty or certification made
to Secured Party in, under or pursuant to this Agreement is false or misleading
in any material respect as of the date deemed made; (iii) if there occurs any
Event of Default (as defined therein) under any Loan Document, or an event
occurs which, whether or not denominated as an Event of Default, expressly
entitles Secured Party to accelerate repayment of any note and/or exercise its
other remedies under the Loan Documents; or (iv) if the holder of any lien or
security interest on any part of the Collateral (without implying Secured
Party's consent to the creation or existence of any such lien or security
interest) gives notice of public or private sale of any portion of the
Collateral or institutes foreclosure or other proceedings for the enforcement of
its remedies under any instrument creating such lien or security interest.

          (B) All cash payments and other proceeds received by Secured Party
with respect to the Collateral may be applied by Secured Party to payment of the
Loans and to payment and performance of the other Obligations in such order and
manner as Secured Party, may elect in its sole and absolute discretion or, at
the election of Secured Party, may be held as additional security for the
Obligations. Upon the occurrence of an Event of Default hereunder or Debtor
otherwise fails to perform any of its duties, covenants, undertakings and
responsibilities contained herein or in any of the other Loan Documents, Secured
Party shall provide to Lender a written Notice of Default at the address set
forth herein and provide to Debtor a period of seven (7) business days from the
date of the Notice of Default in order to cure all defaults under this Agreement
and/or any of the other Loan Documents. If any such defaults remain uncured as
of the close of business on the seventh business day following the date of the
Notice of Default, in addition to its other rights hereunder or any of the other
Loan Documents: Secured Party may exercise any and all other rights, remedies
and recourses under the Loan Documents or now or hereafter existing at law
(including, without limitation, those granted by the applicable Uniform
Commercial Code) or in equity. Notwithstanding anything herein to the contrary,
if Debtor fails or refuses to pay or perform any obligation hereunder, then at
any time thereafter, and without waiving or releasing any other right, remedy or
recourse Secured Party may have, Secured Party may (but shall not be obligated
to), after having provided the notice to Maker required herein, pay or perform
such obligation for the amount of and at the expense of Debtor. Upon demand
therefor, Debtor will reimburse Secured Party for all sums paid by Secured Party
pursuant to this Paragraph, together will interest thereon at the Default Rate
from the date incurred until reimbursed to Secured Party. All such sums shall be
deemed to be part of the Obligations and shall be secured by all the security
for the payment and performance of the Obligations.

          (C) Pursuant to its rights under Paragraph 5(b), and subject to the
terms and conditions hereof, Secured Party and any officer or agent of Secured
Party is hereby constituted and appointed as true and lawful attorney-in-fact of
Debtor with power: (i) to notify or require Debtor to notify any and all account
debtors or parties against which Debtor has a claim that the Receivables have
been assigned to Secured Party and/or that Secured Party has a security interest
therein and that all payments should be made to Secured Party; (ii) to endorse
the name of Debtor upon any invoice, freight or express bill, bill of lading,
storage or warehouse receipt, drafts against account debtors or other obligors
and if Receivables are a part of Collateral, to sign and endorse the name of
Debtor on any assignments, verifications and notices in connection with
Receivables, and any instrument or document relating thereto or to rights of
Debtor therein; (iv) to notify the post office authorities to change the address
for delivery of mail of Debtor to an address designated by Debtor and to
receive, open and dispose of all mail addressed to Debtor; (v) and, to send
requests for verification to account debtors or other obligors; (vi) to sell,
assign, sue for, collect or compromise payment of all or any part of the
Collateral in the name of Debtor or in its own name, or make any other
disposition of Collateral, or any part thereof which disposition may be for
cash, credit or any combination thereof, and Secured Party may purchase all or
any part of the Collateral, at public or, if permitted by law, private sale, and
in lieu of actual payment of such purchase price, may set-off the amount of such
price against the Obligations; granting the Secured Party as the
attorney-in-fact of Debtor, full power of substitution and full power to do any
and all things necessary to be done in and about the premises as fully and
effectually as Debtor might or could do but for this appointment, and hereby
ratifying all that said attorney-in-fact shall lawfully do or cause to be done
by virtue hereof. Neither Secured Party nor its agents shall be liable for any
acts or omissions or for any error judgment of mistake of fact or law in its
capacity as such attorney-in-fact. This power of attorney is coupled with an
interest and shall be irrevocable so long as any Obligations shall remain
outstanding. Secured Party may, in its discretion, at any such sale, restrict
the prospective bidders or purchasers as to their number, nature of business or
qualification given the nature of the Collateral and investment intention.

     Upon any such sale, Secured Party shall have the right to deliver, assign
and transfer to the purchaser thereof the Collateral so sold. Each purchaser at
any such sale shall hold the Collateral so sold absolutely free from any claim
or right of whatsoever kind, including, without limitation, any equity or right
of redemption of Debtor, which Debtor hereby specifically waives to the extent
Debtor may lawfully do so.

     Secured Party shall give Debtor at least ten (10) days written notice of
any such public or private sale. Such notice, in the case of a public sale,
shall state the time and place fixed for such sale. Any such public sale shall
be held at such time or times within ordinary business hours as Secured Party
shall not be obligated to make any sale pursuant to such notice, but if no such
sale is made or only a partial sale is made, subsequent sale. In the case of any
sale of all or any part of the Collateral on credit or for future delivery, the
Collateral so sold may be retained by Secured Party until the selling price is
paid by the purchaser thereof, but Secured Party shall not incur any liability
in case of the failure of such purchaser to take up and pay for the Collateral
so sold, and in case of any such failure, such Collateral may again be sold
under and pursuant to and in compliance with the provisions hereof.
<PAGE>
Security Agreement dated April 30, 2001

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

     Secured Party as attorney-in-fact for Debtor may, in the name and instead
of Debtor, make and execute all conveyances, assignments and transfers of the
Collateral sold pursuant to this Agreement. Nevertheless, Debtor shall, if so
requested by Secured Party, ratify and confirm any sale or sales by executing
and delivering to Secured Party, or to such purchaser or purchasers, all such
instruments as may, in the judgment of Secured Party, be advisable for the
purpose.

     The receipt of Secured Party for the purchase money paid at any such sale
made by it shall be a sufficient discharge therefor to any purchaser of the
Collateral or any portion thereof, and no such purchaser, after paying such
purchase money and receiving such receipt, shall be bound to see to the
application of such purchase money or any part thereof or in any manner
whatsoever be answerable for any loss, misapplication or non-application of any
such purchase money, or any part thereof, or be bound to inquire as to the
authorization, necessity, expediency or regularity of any such sale.

     Secured Party shall have the right to enter and/or remain upon the premises
of Debtor without any obligation to pay rent to Debtor or others, or any other
place or places where any of the Collateral is located and kept and: (i) remove
Collateral therefrom to the premises of Secured Party or any agent of Secured
Party, for such time as Secured Party may desire, in order to maintain, collect,
sell and/or liquidate the Collateral, or (ii) use such premises, together with
materials, supplies, books and records of Debtor, to maintain possession and/or
the condition of the Collateral, and to prepare the Collateral for selling,
liquidating or collection. Secured Party may require Debtor to assemble the
Collateral and make it available to Secured Party at a place to be designated by
Secured Party which is reasonable convenient to both parties.

     Debtor shall be liable for reasonable attorneys' fees and legal expenses
incurred by Secured Party in enforcing any of its rights or remedies hereunder
and, without limiting the rights of Secured Party, the proceeds of disposition
of the Collateral may be applied, in Secured Party's discretion, to payment of
such reasonable attorneys' fees and legal expenses.

          (D) The proceeds of any sale of all or any part of the Collateral
shall be applied in the following order or priorities:

     FIRST, to the payment of all costs and expenses of such sale, including,
without limitation, reasonable compensation to Secured Party, its agents and
attorneys, and all other expenses, liabilities and advances incurred or made by
Secured Party, its agents and attorneys, in connection with such sale, and any
other unreimbursed expenses for which Secured Party may be reimbursed pursuant
hereto;

     SECOND, to the payment of the Loans in such priority as Secured Party shall
choose with no amounts applied to payment of principal until all interest has
been paid;

     THIRD, to the payment or satisfaction of any other Obligations; and
<PAGE>
Security Agreement dated April 30, 2001
Page 10 of 14
--------------------------------------------------------------------------------

     FOURTH, to the payment to Debtor, its successors or assigns, or to
whomsoever may be lawfully entitled to receive the same, or as a court of
competent jurisdiction may direct, of any surplus then remaining from such
proceeds.

     6. NO THIRD PARTY BENEFICIARY. This Agreement and the power of attorney
contained herein are solely for the benefit and protection of Secured Party, its
successors and assigns and are not intended to confer upon any person other than
the parties hereto and their successors and assigns any right or remedies under
or by reason of this instrument. The acceptance of this Agreement shall not
obligate Secured Party to perform any obligation of Debtor under, or take any
other action with respect to, the Collateral or otherwise render Secured Party
liable therefor. All such obligations and liabilities shall continue to remain
upon Debtor as though this Security Agreement had not been made.

     7. INDEMNITY. Debtor will defend, at its own cost and expense, and hold
Secured Party, its officers, directors, employees, shareholders and agents
harmless from and against all loss, damage and expense resulting from an action,
proceedings, liability or claim brought by a third party arising from this
Agreement or actions contemplated by or permitted under this Agreement, except
when due to Secured Party's willful misconduct or Debtor is the prevailing
party; and Debtor will pay all costs and expenses incurred by such persons in
protecting their interests in such an event (including all court costs and
reasonable attorneys' fees). If Secured Party incurs any such loss, damage or
expense, the amount thereof, together with interest thereon at the Default Rate,
shall be deemed to be part of the Obligations, shall be payable by Debtor to
Secured Party immediately, without demand, and shall be secured by all the
security for the payment and performance of the Obligations.

     8. PURSUIT OF RIGHTS. All rights, remedies and recourse of Secured Party
(a) may, in the sole and absolute discretion of Secured Party, be pursued
separately, successively or concurrently and (b) may be exercised as often as
occasion therefor shall arise. Secured Party may resort to any security for the
payment and performance of the Obligations in such order and manner as Secured
Party may elect without affecting the lien and security interest hereof. No
exercise of any right, remedy or recourse of Secured Party shall have the effect
of curing any default of Debtor.

     9. NO DISCHARGE. Neither release, subordination or taking of this Agreement
by Secured Party shall effect the release or discharge of Debtor, Borrowers or
any other person primarily or secondarily liable for the Obligations of any
other security now or hereafter the Obligations, nor shall the taking of
additional security for the performance of the Obligations effect a release or
termination of this Pledge and Security Agreement or any terms or provisions
hereof.

     10. NO WAIVER. Secured Party's delay in insisting or failure to insist upon
strict performance of any obligation of Debtor hereunder shall not be deemed to
be a waiver of strict performance of such obligation or of any other obligation
of Debtor; and Secured Party shall have the right at any time thereafter to
insist upon strict performance of any and all such obligations. No waiver of any
default or breach of any provision of the Agreement shall be considered a waiver
<PAGE>
Security Agreement dated April 30, 2001
Page 11 of 14
--------------------------------------------------------------------------------

of any other or subsequent default or breach, and no delay or omission in
exercising or enforcing any right, remedy or recourse herein granted shall be
construed as a waiver or release thereof or of any other right, remedy or
recourse.

     11. NOTICES. All communications or notices required or permitted to be
given or served under this Agreement shall be in writing and shall be deemed to
have been duly given or made if: (a) delivered in person or by courier (e.g.,
Federal Express), (b) deposited in the United States mail, postage prepaid, for

     12. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective assigns, legal
representatives, executors, heirs and successors, provided, however, that no
party hereto shall have the right to assign any right hereunder or delegate any
obligation hereunder, in whole or in part, without the prior written consent of
the other parties hereto, and any attempt to do so shall be void.

     13. AMENDMENT, MODIFICATION OR WAIVER. No amendment, modification or waiver
of any condition, provision or term of this Agreement shall be valid or of any
effect unless made in writing, signed by the party or parties to be bound and
specifying with particularity the nature and extent of such amendment,
modification or waiver. Failure on the part of any party to complain of any act
or failure to act of another party or to declare another party in default,
irrespective of how long such failure continues, shall not constitute a waiver
by such party of its rights hereunder. Any waiver by any party of any default of
another party shall not affect or impair any right arising from any other or
subsequent default. Nothing herein shall limit the remedies and rights of the
parties hereto under and pursuant to this Agreement.

     14. SEVERABLE PROVISIONS; ENFORCEABILITY. Each provision of this Agreement
is intended to be severable. If any provision hereof shall be declared by a
court of competent jurisdiction to be illegal, unenforceable or invalid for any
reason whatsoever, such illegality, unenforceability or invalidity shall not
affect the validity of the remainder of this Agreement.

     15. ENTIRE AGREEMENT. This Agreement, including the exhibits and schedules
hereto, and the Loan Documents contain the entire understanding and agreement
among the parties hereto with respect to the subject matter hereof, and
supersedes all prior agreements and understandings, express or implied, oral or
written, among the parties with respect to such subject matter. The express
