purpose entity such that the financial statements of the Company shall not be
consolidated with Telex financial statements. The source of funds for such

return of capital pursuant to Section 6.3 and is approved in writing by Telex or

         4.3  No  Interest  on  Capital.  No  interest  shall  be paid by the
Company on the initial or any subsequent contributions to the capital of the
Company.

         4.4  Voluntary Loans to Company. The Members may make voluntary loans
to the Company from time to time for any Company purpose, including payment of
fees to Members, as authorized by the Manager. Any such loans shall not be
treated as contributions to the capital of the company for any purpose

profits and losses and cash distribution of the Company. However, the Company
shall be obligated to such Member for the amount of any such loans, with
interest thereon set at the Prime Rate of interest plus five percent (5%), as
set forth in any agreement creating or evidencing such loan.

         4.5  Additional Contributions and Loans by Members.

              (a) Except for the initial contribution under Section 4.1 and
as provided in this Section 4.5, no Member shall be obligated to make any
additional contributions to the capital of the Company or to make any loans to
or pay any assessments to the Company, and no Member shall be required to
contribute additional capital solely by virtue of having a negative capital
account.

              (b) If required by the Manager, the Members shall advance to
the Company any monies required to pay current expenses, current indebtedness or
any other current financial obligations of the Company which are not funded by
loans to the Company, its gross income or contributions to the capital of the
Company, in proportion to the respective Membership Percentage Interests of the
Members. Such advances shall be deemed "Working Capital Loans". Anything herein
to the contrary notwithstanding, a loan from any affiliate of a Member shall not
be deemed a Working Capital Loan. Requirements for working capital shall be
determined by the Manager and any calls shall be paid within fifteen (15) days
of notice of such call. All Working Capital Loans shall be deemed loans to the
Company and shall be repaid (with interest in the case of advance of
deficiencies only) from the first available funds received by the Company prior
to any other Distributions to Members and, except as provided in Section 4.5(c),
repayment shall be made solely from the assets of the Company and no Member
shall have any liability for the repayment of such Working Capital Loans.

              (c) If any Member (the "Non-Contributing Member") is unable or
fails or neglects to advance or contribute its proportionate share of the
required Working Capital Loan, any other Member (the "Contributing Member") may,
but shall not be required to, advance such deficiency or any portion thereof
(the "Advance"). If more than one Member elects to be a Contributing Member,
such Contributing Member shall allocate the Advance between themselves in
proportion to their respective Membership Percentage Interest. (For convenience
of drafting, the remainder of this Section 4.5 uses the


                                       4

<PAGE>


singular in all cases even though there may be more than one Contributing Member
or Non-Contributing Member.) Any such Advance by a Contributing Member shall
also be considered a loan to the Company but (i) shall bear interest at the rate
equal to five percentage points above the rate publicly announced by Norwest
Bank N.A., Minneapolis, Minnesota or its successor as its "prime rate" or
"reference rate" (the "Prime Rate") on the date such advance is made, (ii)
repayment of such Advance plus interest shall be a personal obligation of the
Non-Contributing Member, and (iii) such Advance plus interest shall be repaid
either from the assets of the Non-Contributing Member or from the portion of all
Company distributions otherwise distributable to the Non-Contributing Member.

              (d) If the Advance plus interest has not been repaid from either
the Non-Contributing Member's share of Company distributions or directly by the
Non-Contributing Member within eighteen (18) months after the date of the
Advance, the Non-Contributing Member shall, at the option of the Contributing
Member, assign a portion of its total Membership Interest determined as follows:
(i) the fair market value of the Company assets less Company liabilities shall
be determined by agreement of the parties or by appraisal (using the procedures
provided in Section 4.5 hereof) as of the date upon which the portion of the
Company Interest shall be transferred, (ii) such fair market value shall be
divided by 100 to establish the value of a Membership Percentage Interest of one
percent, and (iii) a Membership Percentage Interest having a value equal to the
amount of the Advance plus accrued interest thereon, plus, if the parties do not
agree, the costs of appraisals shall be deemed assigned to the Contributing
Member from the Non-Contributing Member. Upon such assignment neither the
Non-Contributing Member nor the Company shall be obligated to repay the Advance.

              (e) Notwithstanding the provisions of subsections (b), (c) or (d)
above, Telex and its successors and assigns shall not be required to make any
additional capital contributions or loans (including Working Capital Loans) to
the Company, shall not be required to make any payment pursuant to subsections
(c) (ii) and (iii), nor will their Membership Percentage Interest be subject to
reduction under this Article IV.

                                       7

Membership Interest of the Electing Member at the value set forth in the Buy -
Sell Notice. The receiving party shall have sixty (60) working days to respond
in writing ("the Response Notice") and shall indicate its election to either
purchase or sell.

         10.3 Closing and Payment. Any closing for the purchase of a Member's
Interest pursuant to this Article X shall occur within sixty (60) days after
receipt of the Response Notice by the Electing Member. The purchase price for
such Member's Interest shall be paid in full in immediately available funds at
closing. If the selling Member or any of its principals or investors have
guaranteed any loans or mortgages of the Company, then as a condition of the
purchase of such Member's Interest under this Article X, such guaranties either
will be released at closing or the purchasing Member will pay off such loans or
mortgages at closing. The closing shall occur at a location agreed upon by both
parties or in the

                                       9

event the parties cannot agree on a location, then at the offices of the company
as set forth herein.

         10.4 Limitations.

              (a) For purposes of this Article X, if Telex is in default under
the Lease at the time of exercise of the right to be the Electing Member and
such default is not cured within the notice or cure period provided therefor
under the Lease, any effective exercise of this right by Telex as Electing
Member shall, at the option of DRF, be terminated.

              (b) If DRF has exercised its right hereunder to purchase the
interest of Telex and at the time of the closing of the purchase of Telex'
interest Telex is in default under the Lease, the purchase price otherwise
payable to Telex hereunder shall be applied first to cure any default under the
Lease, and any remaining purchase price shall be paid to Telex.

                                   ARTICLE XI
              WITHDRAWAL, TRANSFER AND SUBSTITUTION OF MEMBERS

         11.1 Covenant Not to Withdraw, Transfer or Dissolve. Except as
otherwise permitted by this Agreement, each Member hereby covenants and agrees
not to (a) withdraw or attempt to withdraw from the Company, (b) exercise any
power under the Act to dissolve the Company, or (c) transfer all or any portion
of his Membership Interest. Further, each Member hereby covenants and agrees to
continue to carry out the duties of a Member hereunder until the Company is
dissolved and liquidated pursuant to Article XIII hereof.

         11.2 Permitted Transfers.

              (a) A Member may transfer all or any part of his interest in the
Company at any time to (1) an Affiliate of such Member, (2) any other Member or
(3) to any person who is approved by all of the other Members.

              (b) A transferee of a Membership Interest from a Member hereunder
shall be admitted as a Member with respect to such interest if, but only if, (1)
at the time of such transfer, such transferee is an Affiliate of the
transferring Member, (2) at the time of such transfer, such transferee is
otherwise a Member, or (3) the admission of such transferee as a Member is
approved by all of the other Members.

              (c) A transferee who acquires a Membership Percentage Interest
from a Member hereunder by means of a transfer that is permitted under Section
11.2, but who is not admitted as a Member, shall have no authority to act for or
bind the Company, to inspect the Company's books, or otherwise to be treated as
a Member. Such transferee shall be entitled only to allocations and
Distributions with respect to such Membership Percentage Interest in accordance
with this Agreement.

         11.3 Prohibited Transfers. Any purported transfer of any Membership
Interest held by a Member that is not permitted by Section 11.2 shall be null
and void and of no effect whatever; provided that, if the Company is required to
recognize a transfer that is not so permitted (or if the Company, in its sole
discretion elects to recognize a transfer that is not so permitted), the
interest transferred shall be strictly limited to the transferor's rights to
allocations and Distributions as provided by this Agreement


                                       10


<PAGE>


with respect to the transferred interest, which allocations and Distributions
may be applied (without limiting any other legal or equitable rights of the
Company) to satisfy the debts, obligations, or liabilities for damages that the
transferor or transferee of such interest may have to the Company.

         11.4 Termination of Status as Member. A Member shall cease to be a
Member upon the first to occur of (1) such Member's death, permanent disability,
or mental incompetence, (2) the bankruptcy of a Member, or (3) the involuntary
transfer by operation of law of such Member's Membership Interest. If a Member
ceases to be a Member for any reason hereunder, such Person shall continue to be
liable for all debts and obligations of the Company that the Member was liable
for by reason of being a Member. A Person shall not be liable as a Member for
the debts and obligations of the Company except to the extent such liability
arises solely by reason of being a Member of the Company and, in any event,
shall not be liable for Company debts and obligations arising after such Person
ceases to be a Member. Any debts, obligations, or liabilities to the Company of
any Person who ceases to be a Member shall be collectible by any legal means and
the Company is authorized, in addition to any other remedies at law or in
equity, to apply any amounts otherwise distributable or payable by the Company
to such Person to satisfy such debts, obligations, or liabilities.

         11.5 Purchase by Surviving Member. In the event a Member ceases to be a
Member pursuant to Section 11.4 and the business of the Company is continued
without dissolution under Section 13.1, the remaining Member shall acquire such
terminated Member's Financial Rights in the Company in the following manner:

              (a) The acquiring Member shall give written notice to the
terminated Member identifying the price that the acquiring Member is willing to
pay for the interest of the terminated Member in the Company, and shall identify
a date at least 60 days after the date of the notice for closing the purchase
and sale transaction.

              (b) Within 30 days after the date the terminated Member receives
such notice of exercise from the acquiring Member, the terminated Member shall
respond in writing to the acquiring Member, either accepting the terms contained
in acquiring Member notice, or demanding appraisal pursuant to subsection (c).
If the terminated Member fails to respond within such time, the terminated
Member shall be deemed to have accepted the price proposed by the acquiring
Member in its notice.

              (c) If the terminated Member elects appraisal of its interest in
the Company, the price of its interest to be purchased by the acquiring Member
shall be equal to the net proceeds which would be distributed to the terminated
Member if the Company dissolved and was liquidated after selling its assets at a
price determined by an appraisal conducted by a qualified MAI appraiser with
experience appraising real property in the area in which the property to be
appraised is located.

              (d) If, for any reason, the price cannot be so ascertained in time
for the purchase and closing as specified in this Section, the parties shall, in
good faith, make their best estimate of what the purchase price would be in
accordance with the foregoing, and closing shall be made on that estimate as a
tentative price. When the price is finally ascertained, it shall be compared to
the tentative price, and any overage shall promptly be refunded by the
terminated Member, or any deficiency shall promptly be paid by the acquiring
Member. In all cases, such adjustment shall be made within 10 days after the
price is finally ascertained.



                                       11

<PAGE>


              (e) If this option is exercised, the closing of the purchase shall
be at a time and place agreeable to the parties, but in any event no later than
90 days after the giving of the required notice. Upon the closing, the purchase
price shall be paid in cash or by wire transfer or cashier's check.

              (f) The appraiser shall be selected by agreement of the parties.
If the parties cannot agree upon the appraiser, the parties shall each name an
appraiser who meets the qualifications set forth above, and the value shall be
the average of the two appraisals. In issuing the assignment to the appraiser,
the appraiser shall be instructed to determine the market value of all of the
assets of the Company taking into account the status of the Lease and any debt
financing after the event giving rise to the termination of the terminated
Member's interest.

                                   ARTICLE XII
                               BREACH OF AGREEMENT

         12.1 If any Member ("Defaulting Member") should default in his
performance of any obligation arising under this Agreement (including without
limitation the transfer of any Membership Interests in violation of Article XI),
any other Member or Members ("Nondefaulting Members") may enforce the specific
performance of this Agreement and/or may pursue any other remedies at law or at
equity. The Defaulting Member shall be liable to the Company for all costs and
expense (including attorneys' fees) in connection with such default and the
exercise of any remedies set forth herein.


                                  ARTICLE XIII
                           TERMINATION AND LIQUIDATION

         13.1 Events Causing Liquidation. The Company will dissolve, liquidate
and its business will not be continued upon the happening of any of the
following events:

              (a) Upon written consent of all Members;

              (b) Upon the expiration of the term of the Company as specified in
Section 1.4 unless such term is extended by amendment to this Agreement;

              (c) Upon the sale, exchange or other disposition of all or
substantially all of the assets of the Company;

              (d) The insolvency or bankruptcy of the Company;

              (e) On the occurrence of any event which, under the laws of the
State of Minnesota and notwithstanding the terms of this Agreement, shall
terminate the Company and require it to be liquidated.

Notwithstanding the foregoing, upon the occurrence of any event that would
otherwise cause the dissolution of the Company, under this Agreement, the Act or
otherwise, the Company shall promptly send a notice of such fact to each Member.
If the Members holding at least a majority of the outstanding Membership
Interests (excluding the interests of any Person who has ceased to be a Member)
or if Telex in its sole discretion shall consent to the continuation of the
business of the Company without

                                       12




<PAGE>


dissolution, then the Company shall not dissolve and shall not be required to be
wound up.

         13.2 Distribution on Liquidation. Upon an event of liquidation, the
business of the Company shall be wound up, the Manager shall take full account
of the Company assets and liabilities, and all assets shall be liquidated as
promptly as is consistent with obtaining the fair value thereof. If any assets
are not sold, gain or loss shall be allocated to the Members in accordance with
Article VI as if such assets had been sold at their fair market value at the
time of liquidation. If any assets are distributed to a Member, rather than
sold, the Distribution shall be treated as a Distribution equal to the fair
market value of the asset at the time of the liquidation. The assets of the
Company shall be used and distributed in the following order of priority:

              (a) To the payment of all debts and liabilities of the Company,
including all fees due the Members and their Affiliates, and including any loans
or advance that may have been made by the Members to the Company, in the order
of priority as provided by law;

              (b) To the establishment of any reserves reasonably deemed
necessary by the Manager or the Person winding up the affairs of the Company for
any contingent liabilities or obligations of the Company;

              (c) To DRF in an amount equal to $1,108,000 (less any amounts
which have been paid to DRF under Section 6.3(c) in respect of any Distributions
made from the proceeds of a refinancing or refinancings;

              (d) To Telex in an amount equal to the amount distributed to DRF
under (c) above; and (e) To the extent of any balance remaining to each Member,
ratably in proportion to its respective Membership Percentage Interest.

                                   ARTICLE XIV
                             AMENDMENT OF AGREEMENT

for partition of any Company property.

         15.3 Consent and Waiver. No consent under and no waiver of any
provision of this Agreement on any one occasion shall constitute a consent under
