and deliver such promissory notes, mortgages, security agreements, pledge
agreements, certificates, instruments, documents and other items (the "Initial
Loan Documents") with regard to the Company and its properties and assets as
the Manager, in his sole discretion, deems appropriate. The Members acknowledge
and agree that it is in the best interests of the Company, and that it is
necessary for the Company, to borrow the funds to be provided by the Initial
Loans and that such Initial Loans will constitute substantial liabilities of the
Company and could cause the Company to cease operations and become insolvent if
the Company does not fulfill its obligations under the Initial Loan Documents.
The Members irrevocably authorize the Manager on behalf of the Company to take
all actions which the Manager, in his sole discretion, deems necessary or
expedient to consummate the Initial Loans including, but not limited to, the
execution of the Initial Loan Documents containing such terms and provisions as
the Manager, in his sole discretion, deems appropriate. The authorization set
forth in the prior sentence shall be deemed to be coupled with an interest,
shall be deemed to be for adequate consideration, and shall be irrevocable. No
further authorization or direction from the Members shall be required for the
Manager to be deemed to be fully authorized to act for, and to bind, the Company
with regard to the Initial Loans and the Initial Loan Documents. The Manager is
authorized to consummate the transactions involving the Initial-Loans in such
order and at times as the Manager, in his sole discretion, determines; PROVIDED,
HOWEVER, that the Manager in his sole discretion may elect to not consummate all
Initial Loans and/or to procure such substitute loans for any Initial Loans not
consummated all as the Manager, in his sole discretion, deems appropriate;
PROVIDED, FURTHER, in no event shall the aggregate principal amount

                                      - 4 -
<Page>

of the Initial Loans and loans procured in substitution therefor exceed the
principal amount of $3,000,000.00 at the time of consummation of the last of
such loans to be consummated without the express written prior consent of all of
the Members.

     (b)    OTHER LOANS. Without limitation upon Section 3.6.(a), the Manager
may, at any time and from time to time, make or cause a loan to be made to the
Company by a Member in any amount and on those terms upon which the Member
making such loans and the Manager shall agree.

Balance relates to the Interest transferred.

     "Capital Proceeds" means the gross receipts received by the Company from a

                 (C)  the balance, to the Members in proportion to their

     4.4    SPECIAL ALLOCATIONS.

            (a)  QUALIFIED INCOME OFFSET. No Member shall be allocated Losses or
deductions if the allocation causes a deficit in the Member's Adjusted Capital
Account. If a Member receives (l) an allocation of Loss or deduction (or item
thereof) or (2) any distribution, which causes a deficit in the Member's
Adjusted Capital Account at the end of any taxable year, then all items of
income and gain of the Company (consisting of a pro rata portion of each item
of Company income, including gross income and gain) for that taxable year shall
be allocated to that Member, before any other allocation is made of Company
items for that taxable year, in

                                      - 9 -
<Page>

the amount and in proportions required to eliminate the excess as quickly as
possible. This Section 4.4(a) is intended to comply with, and shall be
interpreted consistently with, the "qualified income offset" provisions of the
Regulations promulgated under Code Section 704(b). In the event that Profits or
Losses or items thereof are allocated to one or more Members pursuant to this
Section 4.4(a), subsequent Profits and Losses shall first be allocated (subject
to the provisions of this Section 4.4(a)) to the Members in a manner designed
to result in each member having a Capital Account equal to what it would have
been had the original allocation of Profits or Losses or items thereof pursuant
to Section 4.4 (a) not occurred.

            (b)  MINIMUM GAIN CHARGEBACK. Except as set forth in Regulation
Section 1.704-2(f)(2), (3), and (4), if, during any taxable year, there is a
net decrease in Minimum Gain, each Member, prior to any other allocation
pursuant to this Article 4, shall be specially allocated items of gross income
and gain for such taxable year (and, if necessary, subsequent taxable years) in
an amount equal to that Member's share of the net decrease of Minimum Gain,
computed in accordance with Regulation Section 1.704-2(g). Allocations of gross
income and gain pursuant to this Section 4.4(b) shall be made first from gain
recognized from the disposition of Company assets subject to non-recourse
liabilities (within the meaning of the Regulations promulgated under Code
Section 752), to the extent of the Minimum Gain attributable to those assets,
and thereafter, from a pro rata portion of the Company's other items of income
and gain for the taxable year. It is the intent of the parties hereto that any
allocation pursuant to this Section 4.4(b) shall constitute a "minimum gain
chargeback" under Regulation Section 1.704-2(f). With respect to a net decrease
in Member Loan Minimum Gain, items of gross income and gain shall be specially
allocated in a manner consistent with the principles of the preceding sentence
and Regulation Section 1.704-2(i)(4).

            (c)  CONTRIBUTED PROPERTY AND BOOK-UPS. In accordance with Code
Section 704(c) and the Regulations thereunder, as well as Regulation Section
1.704-1(b)(2)(iv)(d)(3), income, gain, loss, and deduction with respect to
any property contributed (or deemed contributed) to the Company shall, solely
for tax purposes, be allocated among the Members so as to take account of any
variation between the adjusted basis of the property to the Company for federal
income tax purposes and its fair market value at the date of contribution (or
deemed contribution). If the adjusted book value of any Company asset is
adjusted as provided herein, subsequent allocations of income, gain, loss, and
deduction with respect to the asset shall take account of any variation between
the adjusted basis of the asset for federal income tax purposes and its adjusted
book value in the manner required under Code Section 704(c) and the
Regulations thereunder.

                                     - 10 -
<Page>

            (d)  CODE SECTION 754 ADJUSTMENT. To the extent an adjustment to the
tax basis of any Company asset pursuant to Code Section 734(b) or Code Section
743(b) is required, pursuant to Regulation Section 1.704-1(b)(2)(iv)(m), to be
taken into account in determining Capital Accounts, the amount of the adjustment
to the Capital Accounts shall be treated as an item of gain (if the adjustment
increases the basis of the asset) or loss (if the adjustment decreases basis),
and the gain or loss shall be specially allocated to the Members in a manner
consistent with the manner in which their Capital Accounts are required to be
adjusted pursuant to that Section of the Regulations.

            (e)  NONRECOURSE DEDUCTIONS. Nonrecourse Deductions for a taxable
year or other period shall be specially allocated among the Members in
proportion to their Percentage Interests.

            (f)  MEMBER LOAN NONRECOURSE DEDUCTIONS. Any Member Loan Nonrecourse
Deduction for any taxable year or other period shall be specially allocated to
the Member who bears the risk of loss with respect to the loan to which the
Member Loan Nonrecourse Deduction is attributable in accordance with Regulation
Section 1.704-2(i).

            (g)  GUARANTEED PAYMENTS. To the extent any compensation paid to any
Member by the Company, including any fees payable to any Member pursuant to
Section 5.3 hereof, is determined by the Internal Revenue Service not to be a
guaranteed payment under Code Section 707(c) or is not paid to the Member
other than in the Person's capacity as a Member within the meaning of Code
Section 707(a), the Member shall be specially allocated gross income of the
Company in an amount equal to the amount of that compensation, and the Member's
Capital Account shall be adjusted to reflect the payment of that compensation.

            (h)  UNREALIZED RECEIVABLES. If a Member's Interest is reduced
(provided the reduction does not result in a complete termination of the
Member's Interest), the Member's share of the Company's "unrealized receivables"
and "substantially appreciated inventory" (within the meaning of Code Section
751) shall not be reduced, so that, notwithstanding any other provision of this
Agreement to the contrary, that portion of the Profit otherwise allocable upon a
liquidation or dissolution of the Company pursuant to Section 4.4 hereof which
is taxable as ordinary income (recaptured) for federal income tax purposes
shall, to the extent possible without increasing the total gain to the Company
or to any Member, be specially allocated among the Members in proportion to the
deductions (or basis reductions treated as deductions) giving rise to such
recapture. Any questions as to the aforesaid allocation of ordinary income
(recapture), to the extent such questions cannot be resolved in the manner
specified above, shall be resolved by the Manager.

            (i)  WITHHOLDING. All amounts required to be withheld pursuant to
Code Sections 1441, 1445 and 1446 or any other provision of federal, state, or
local tax law shall be treated as amounts actually distributed to the affected
Members for all purposes under this Agreement.

     4.5.   LIQUIDATION AND DISSOLUTION.

            (a)  LIQUIDATION. If the Company is liquidated, the assets of the
Company shall be distributed to the Members in accordance with the balances in
their respective Capital Accounts, after taking into account the allocations of
Profit or Loss pursuant to Sections 4.2(a) and 4.3(a) and (b), if any, and
distributions, if any, of cash or property pursuant to Sections 4.2(b) and
4.3(c).

            (b)  RESERVED.

     4.6.   GENERAL.

            (a)  TIMING OF DISTRIBUTION. Except as otherwise provided in this
Agreement, the timing and amount of all distributions shall be determined by the
Manager.

            (b)  DISTRIBUTION OF ASSETS. If any assets of the Company are
distributed in kind to the Members, those assets shall be valued on the basis of
their fair market value, and any Member entitled to any interest in those assets
shall receive that interest as a tenant-in-common with all other Members so
entitled. Unless the Members otherwise agree, the fair market value of the
assets shall be determined by an independent appraiser who shall be selected by
the Manager. The Profit or Loss for each unsold asset shall be determined as if
the asset had been sold at its fair market value, and the Profit or Loss shall
be allocated as provided in Section 4.3(a) and (b) and shall be properly
credited or charged to the Capital Accounts of the Members prior to the
distribution of the assets in liquidation pursuant to Section 4.5.

            (c)  ALLOCATION. All Profit and Loss shall be allocated, and all
distributions shall be made to the Persons shown on the records of the Company
to have been Members as of the last day of the taxable year for which the
allocation or distribution is to be made. Notwithstanding the foregoing, unless
the Company's taxable year is separated into segments, if there is a Transfer or
an Involuntary Withdrawal during the taxable year, the Profit and Loss shall be
allocated between the original Member and the successor on the basis of the
number of days each was a Member during the taxable year; PROVIDED, HOWEVER, the
Company's taxable year shall be segregated into two or more segments in order to
account for

                                     - 12 -

Profit, Loss or proceeds attributable to Capital Transaction or to any other
extraordinary non-recurring items of the Company.

            (d)  AMENDMENT. The Manager is hereby authorized, upon the advice
of the Company's tax counsel, to amend this Article 4 to comply with the Code
and the Regulations promulgated under Code Section 704(b); provided, however,
that no amendment shall materially affect distributions to a Member without
the Member's prior written consent.

     ARTICLE 5: MANAGEMENT.

     5.1.   MANAGEMENT.

            (a)  MANAGER. Gallo is hereby appointed the manager of the Company
(the "Manager"). The business and affairs of the Company shall be managed under
the direction and control of the Manager, and all powers of the Company shall be
exercised by or under the authority of the Manager. No other Person shall have
any right or authority to act for or bind the Company except as permitted in
this Agreement or as required by law.

            (b)  GENERAL POWERS. The Manager shall have the full power to
execute and deliver, for and on behalf of the Company, any and all documents and
instruments which may be necessary or desirable to carry on the business of the
Company, including, without limitation, any and all deeds, contracts, leases,
mortgages, deeds of trust, promissory notes, security agreements and financing
statements pertaining to the Company's assets or obligations. No person dealing
with the Manager need inquire into the validity or propriety of any document or
instrument executed in the name of the Company by the Manager, or as to the
authority of the Manager in executing the same.

            (c)  LIMITATION ON AUTHORITY OF MEMBERS.

                 (i)   No Member is an agent of the Company solely by virtue of
being a Member, and no Member has authority to act for the Company solely by
virtue of being a Member.

                 (ii)  Any Member who takes any action or binds the Company in
violation of this Section 5.1(c) shall be solely responsible for any loss and
expense incurred by the Company as a result of the unauthorized action and shall
indemnify and hold the Company harmless with respect to the loss or expense.

            (d)  REMOVAL OF MANAGER. If any one or more of the following events
occurs, the Members may remove the Manager, and elect a new Manager:

            (ii)  The Manager's Involuntary Withdrawal, if he is a Member; or

            (iii) The resignation, death or incapacity of the Manager.

     The determination of whether one or more of such events exist shall be made
by those Members holding at least thirty-two (32) of the Percentages then held
by Members and shall be final, binding and not reviewable unless the decision
was based on a material mistake of fact or law or was arbitrary and capricious.

            (e)  SUCCESSOR MANAGER. In the event that the then serving Manager
is removed, or, for any reason whatsoever, ceases to serve, a successor Manager
shall be chosen by a vote of 100% of the persons who are then Members excluding
the Manager who has been removed in the event such Manager is a Member. If the
Members cannot agree on a successor Manager within fifteen (15) days after a
vacancy in the position of Manager occurs, then the Company shall be managed by
the members holding 70% of the Interests in the Company until a successor
Manager is chosen. Notwithstanding the foregoing, all Members irrevocably

whatsoever.

     5.2.   MEETINGS OF AND VOTING BY MEMBERS.

calling the meeting shall give written notice of the meeting to each Member
entitled to vote at the meeting. The notice shall state the time, place and

who is entitled to notice may waive notice if before or after the meeting the
Member signs a waiver of the notice which is filed with the records of Members'
meetings. Notice is also waived if a Member is present at the meeting in person
or by proxy without protesting the adequacy of notice at the outset. Unless this
Agreement provides otherwise, at a meeting of Members, the presence in person or
by proxy of Members holding not less than majority of the Percentages then held
by Members constitutes a quorum. A Member may vote either in person or by
written proxy signed by the Member or by the Member's duly authorized
attorney-in-fact.

in any year without the consent of Members holding 100% of the Percentages. Upon
substantiation of the amount and purpose thereof, the Manager shall be entitled
to reimbursement for expenses reasonably incurred in connection with the
activities of the Company.

            (c)  The Manager is entitled to hire such employees as the Manager
deems necessary or expedient for the proper operation of the Company and to pay
such employees reasonable compensation as determined by the Manager. The Manager
is specifically authorized to retain Mackley as Operations Manager of the

to notify the Members of Manager's intention to execute any such document and,
if practicable, to obtain the Member's signatures thereon.

            (b)  IRREVOCABILITY. The foregoing power of attorney is irrevocable
and is coupled with an interest, and, to the extent permitted by applicable law,
shall survive the death or disability of a Member. It also shall survive the
Transfer of an Interest, except that if the transferee is admitted as a Member,
this power of attorney shall survive the delivery of the assignment for the sole
purpose of enabling the Attorney-in-Fact to execute, acknowledge and file any
documents needed to effectuate the substitution. Each Member shall be bound by
any representations made by the Attorney-in-Fact acting in good faith pursuant

            (c)  REASONABLENESS. Each Member hereby acknowledges the
reasonableness of the prohibition contained in this Section 6.2 in view of the

Person (a "Transferee") to purchase all or any portion of the Transferor's
Interest (the "Transferor "Interest") then, prior to any Transfer of the

"Remaining Members") written notice (the "Transfer Notice") containing each of

<Page>

            (b)  OFFER PERIOD. The Offer shall be and remain irrevocable for a
period (the "Offer Period") ending at 11:59 P.M. local time at the Company's
principal office, on the thirtieth (30th) day following the date the Transfer
Notice is given to the Remaining Members. At any time during the Offer Period, a
Remaining Member may accept the offer by notifying the Transferor in writing
that the Remaining Member intends to purchase all, but not less than all, of the
Transferor Interest. If two (2) or more Remaining Members desire to accept the
Offer, then, in the absence of an agreement between or among them, each such
Remaining Member shall purchase the Transferor Interest in the proportion that
his respective Percentage bears to the total Percentages of all of the Remaining
Members who desire to accept the Offer. If one or more Remaining Members accept
the Offer, then the parties shall fix a closing date (the "Transfer Closing
Date") for the purchase, which shall not be earlier than ten (10) or more than
ninety (90) days after the expiration of the Offer Period.

            (c)  ACCEPTANCE OF OFFER. If any Remaining Member accepts the Offer,
the Transfer Purchase Price shall be paid in immediately available funds on the
Transfer Closing Date in accordance with the payment terms set forth in the
Transferee Offer; PROVIDED, HOWEVER, if the Transferee Offer is payable in
installments, each Remaining Member who accepts the Offer may pay the Transfer
Purchase Price in the same manner as would the Transferee if the Transferee
Offer has been accepted by the Transferor.

            (d)  FREE TRANSFER PERIOD. If no Remaining Member accepts the Offer
(within the time and in the manner specified in this Section), then the
Transferor shall be free for a period (the "Free Transfer Period") of thirty
(30) days after the expiration of the Offer Period to Transfer the Transferor
Interest to the Transferee, for the same or greater price and on the same terms
and conditions as set forth in the Transfer Notice. The Transfer shall be
subject, however, to the Conditions of Transfer (other than Section 6.2(a)(vi)).
If the Transferor does not Transfer the Transferor Interest within the Free
Transfer Period, the Transferor's right to Transfer the Transferor Interest
pursuant to this Section shall cease and terminate.

            (e)  TRANSFER VOID. Any Transfer by the Transferor after the last
day of the Free Transfer Period or without strict compliance with the terms,

     6.5    VOLUNTARY WITHDRAWAL. No Member shall have the right or power to
Voluntarily Withdraw from the Company, except as otherwise provided by this
Agreement.

     6.6.   WITHDRAWAL. Upon the Voluntary Withdrawal of a Member where the
Company is continued as provided in Section 7.1.(c), the Withdrawing Member
shall not be entitled to receive in liquidation of the interest in the Company,
pursuant to Section 32 of the Act, the fair market value of the Member's
Interest as of the date the Member withdrew from the Company. Upon an
Involuntary Withdrawal of a Member where the Company is continued as provided in
Section 7.1(c) and the Member's Interest is not purchased by the Company
pursuant to Section 6.7, the Withdrawing Member shall be entitled to be paid by
the Company the Appraised Value of the Member's Interest over such period of
time and on such other terms as Members holding a majority of the Interests in
the Company (excluding the Interests of the Withdrawing Member) so determine;
PROVIDED, HOWEVER, that the obligations of the Company to make payments pursuant
to this Section 6.6 shall be effective only to the extent that there is
sufficient cash flow to pay all operating expenses of the Company; PROVIDED,
FURTHER, that any payments not made shall be deferred to, and made when, the
Company has sufficient cash flow to make such payment. A Withdrawing Member must
exercise his rights pursuant to this Section 6.6 not later than the sixtieth
(60th) day following the expiration of the Withdrawal Offer Period set forth in
Section 6.7(b).

     6.7.   OPTIONAL BUY-OUT IN EVENT OF INVOLUNTARY WITHDRAWAL.

            (a)  WITHDRAWAL OFFER. If the Members elect to continue the Company
after an Involuntary Withdrawal, the withdrawn Member shall be deemed to offer
for sale (the "Withdrawal Offer") to the Company the Interest owned of record
and beneficially by the withdrawn Member (the "Withdrawal Interest"). The
buy-out provisions of this Section 6.7 shall be in lieu of any buy-out rights
the withdrawn Member may have from the Company pursuant to the Act or otherwise.

            (b)  WITHDRAWAL OFFER PERIOD. The Withdrawal Offer shall be and
remain irrevocable for a period (the "Withdrawal Offer Period") ending at 11:59
P.M., local time at the Company's principal office on the sixtieth (60th) day
following the date the Member elect to continue the Company. At any time during
the Withdrawal Offer Period, the Company may accept the Withdrawal Offer by
notifying the withdrawn Member (the "Withdrawal Notice") of its acceptance. The
withdrawn Member shall not be deemed a Member or Manager for the purpose of the
vote on whether the Company shall accept the Withdrawal Offer.

                                     - 23 -
<Page>

            (c)  WITHDRAWAL CLOSING DATE. If the Company accepts the Withdrawal
Offer, the Withdrawal Notice shall fix a closing date (the "Withdrawal Closing
Date") for the purchase which shall be not earlier than ten (10) or later than
ninety (90) days after the expiration of the Withdrawal Period.

            (d)  WITHDRAWAL PURCHASE PRICE. If the Company accepts the
Withdrawal Offer, the Company shall purchase the Withdrawal Interest for a price
equal to the amount the withdrawn Member would receive if the Company were
liquidated and an amount equal to the Appraised Value were available for
distribution to the Members pursuant to Section 4.5 (the "Withdrawal Purchase
Price"). The Withdrawal Purchase Price shall be paid in cash on the Withdrawal
Closing Date.

            (e)  FAILURE TO ACCEPT WITHDRAWAL OFFER. If the Company fails to
accept the Withdrawal Offer, then the withdrawn Member or the withdrawn Member's
successor, as the case may be, upon the expiration of the Withdrawal Offer
Period, thereafter shall be treated as the unadmitted assignee of a Member.

     6.8.   APPRAISED VALUE.

            (a)  APPRAISAL. The term "Appraised Value" means the appraised value
of the Withdrawn Member's equity in the Company's assets as hereinafter
provided. Within fifteen (15) days after demand by either one to the other, the
Company and the withdrawn Member shall each appoint an appraiser to determine
the value of the equity in the Company's assets. If the two appraisers agree
upon Withdrawn Member's equity value, they shall jointly render a single written
report stating that value. If the two appraisers cannot agree upon such equity
value, shall each render a separate written report and shall appoint a third
appraiser, who shall appraise the Company's assets and determine the value of
the Withdrawn Member's equity therein, and shall render a written report of his
opinion thereon. Each party shall pay the fees and other costs of the appraiser
appointed by that party, and the fees and other costs of the third appraiser
shall be shared equally by both parties. In determining the appraised value of
the seller's equity in the Company, the appraisers shall take into account, if
appropriate, any discount for lack of marketability and minority interest.

            (b)  CERTAIN DETERMINATIONS. The equity value contained in the
aforesaid joint written report or written report of the third appraiser, as the
case may be, shall be the Appraised Value; provided, however, that if the value
of the equity contained in the appraisal report of the third appraiser is more
than the higher of the first two appraisals, the higher of the first two
appraisals shall govern; and provided, further, that if the value of the equity
contained in the appraisal report of the third appraiser is

                                     - 24 -
<Page>

less than the lower of the first two appraisals, the lower of the first two
appraisals shall govern.

     6.9.   INSTALLMENT PURCHASE. If the Company or the Remaining Members, as
the case may be (the "Purchaser"), elect to pay the Withdrawal Purchase Price on
an installment basis (the "Indebtedness"), the Purchaser shall evidence the
obligation to pay the Indebtedness by executing and delivering under seal its or
their promissory note to the withdrawn Member or the Transferor (the "Payee") in
the form approved by the Manager.

     6.10.  INSOLVENCY.

            (a)  CORRECTIVE ACTION. If the Company is not lawfully permitted to
purchase all of the interest of a Member as required pursuant to this Agreement
or to pay, from time to time, any amount owed with respect to the deferred
Purchase Price (the "Indebtedness"): (i) the entire amount which may lawfully be
paid shall be paid immediately on such account; and (ii) the surviving or
remaining Members shall promptly take those steps that are appropriate or
necessary to enable the Company to pay the balance which is then due, including,
by way of illustration and not by way of limitation, the obtaining of an
up-to-date appraisal of the assets of the Company or including in any note given
to evidence the Indebtedness that language which is required (under Section 35
of the Act) to allow the Company to issue the note (and the payee hereby
consents to the inclusion of that language in the note), provided that the
foregoing shall not require any Member to make any capital contribution.

            (b)  ASSUMPTION. If the Company is unable to pay lawfully for the
Interest of a Member purchased under the applicable provisions of this Agreement
after taking all of the actions specified in clause (ii) of Section 6.10(a) of
this Agreement, then the surviving or remaining Members, at their option, may
assume the Company's obligation to purchase and shall purchase the balance of
the Interest of a Member to be purchased under the applicable provisions of this
Agreement, at the price and subject to the other terms and conditions set forth
in this Agreement. In such event, each surviving or remaining Member who agrees
to assume the Company's obligation as set forth in the prior sentence; PROVIDED,
HOWEVER, that Member shall pay for his pro rata portion of the Interest of the
Member.

     ARTICLE 7: DISSOLUTION.

happening of any of the following events:
