SECTION 3.1 BUSINESS

      The purpose of the Company shall be to engage in the management of market

manufacturing, and commercialization of wireless products (the "Products") in
Latin America and to engage in any and all activities incident to or in

aspects of (i) their business relationship with each other and (ii) the
organization, operation and governance of the Company and its business. They

SECTION 3.3. INVALIDITY AND UNREASONABLENESS OF EXPECTATIONS NOT INCLUDED IN
             THIS AGREEMENT

      (a)   The Members fear the uncertainty and the potential for discord that
would exist if the unstated expectation of any Member can be used to gain
advantage through litigation.

      (b)   The Members therefore agree that:

            (i) it is unreasonable for any Member to have or rely on an
expectation that is not reflected in this Agreement, the Articles of
Organization or the Act;

            (ii)  any Member who has or develops an expectation contrary to or
in addition to this Agreement, the Articles of Organization or the Act has a
duty to

                  (A)   immediately inform all other Members, and

                  (B)   promptly attempt to have this Agreement amended to
reflect the expectation;

            (iii) the failure of a Member who has or develops an expectation
contrary to or in addition to the contents of this Agreement to obtain an
amendment of this Agreement as provided in Section 3.3(b)(ii) is evidence that
the expectation was not reasonable and estops that Member from asserting that
expectation as a basis for any claim against the Company or any other Member.

SECTION 3.4. ADVICE OF COUNSEL

      Each Member hereby:

      (a)   understands, agrees and acknowledges that this Agreement contains
legally binding provisions, and

      (b)   has either consulted their or its own lawyer or consciously decided
not to consult their or its lawyer regarding this Agreement and such Member's
rights and obligations hereunder.

working capital reserves; provided, however, that the Company shall distribute,
on an annual basis, such amounts to the Members as necessary to enable the
Member with the highest tax rate to pay all applicable taxes payable by the
Member on the allocation to it of Company profits. The immediately preceding
sentence shall in no manner be deemed to modify Section 6.3(a) below with

<PAGE>

                                  ARTICLE VII.

                                   TAX MATTERS

SECTION 7.1. TAX CHARACTERIZATION AND RETURNS

      (a)   It is the intent of the Members that the Company will be treated as
a partnership (and not as a corporation) for federal and state tax purposes. All
provisions of this Agreement and the Articles of Organization are to be
construed to preserve that tax status.

      (b)   Within ninety (90) days after the end of each Fiscal Year, the
Members will cause to be delivered to each person who was a Member at any time
during such Fiscal Year a

                                        9
<PAGE>

Schedule K-l and such other information as may be necessary for the preparation

SECTION 7.2. CAPITAL ACCOUNTS

      The Company will establish a Capital Account for each Member and will
maintain each Capital Account according to the following rules:

      (a)   Maintenance. The Company will maintain the Capital Accounts in
accordance with Treasury Regulations Section 1.704-l(b)(2)(iv).

      (b)   Negative Capital Account and Qualified Income Offset. A Member shall
not be liable to fund any deficit in that Member's Capital Account at any time.
Notwithstanding any other provision of this Agreement, if a Member receives an
adjustment, allocation, or distribution as described in Treasury Regulations
Section 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-
1(b)(2)(ii)(d)(6), and such adjustment, allocation, or distribution results in a
deficit balance in that Member's Capital Account, the Member will be allocated
items of income and gain in an amount and manner sufficient to eliminate the
deficit balance or the increase in the deficit balance as quickly as possible.
It is intended that this subdivision will meet the requirements of a "qualified
income offset" as defined in Treasury Regulations Section 1.704-1 (b)(2)(ii)(d),
and this subdivision is to be interpreted and applied consistent with that
intention.

      (c)   Non-recourse Deductions. If a Member's Capital Account has a deficit
balance at any time and the deficit or increase in deficit was caused by the
allocation of non-recourse deductions as defined in Treasury Regulations Section
1.704-2(b), then beginning in the first taxable year of the Company in which
there are non-recourse deductions or in which the Company makes a distribution
of proceeds of a non-recourse liability that are allocable to an increase in
minimum gain as defined in Treasury Regulations Section 1.704-2(d) and
thereafter throughout the full term of the Company, the following rules shall
apply:

            (i)   Non-recourse deductions shall be allocated to the Members in a
manner that is reasonably consistent with the allocations that have substantial
economic effect as defined in Treasury Regulations Section 1.704-1 or some other
significant item attributable to the property securing the non-recourse
liabilities, if applicable; and

            (ii)  If there is a net decrease in minimum gain for a taxable year,
each Member will be allocated items of Company income and gain for that year
equal to that Member's share of the net decrease in minimum gain as defined in
Treasury Regulations Section 1.704-2(g)(2).

SECTION 7.3. ACCOUNTING DECISIONS

      (a)   The Board of Managers shall make all decisions as to the Company's
accounting matters.

      (b)   The Board of Managers may, in their sole discretion, cause the
Company to make any elections available under the Code.

SECTION 9.9. ACTION WITHOUT A MEETING

      Any action required or permitted to be taken at a meeting of the Members
may be taken without a meeting by written consent signed by the Members who own
the number of Units which would be required to take the same action at a meeting

                               TRANSFERS OF UNITS

SECTION 11.1. RESTRICTIONS ON TRANSFERS

      (a)   No Member shall voluntarily or involuntarily (whether by operation
of law or otherwise) sell, assign, transfer, devise, encumber, pledge, give,
devise, bequeath, hypothecate or otherwise dispose of ("Transfer") any or all of
its Units now or hereafter legally or beneficially owned by a Member, except as
otherwise specifically provided in this Agreement. Any Transfer of Units made by
any Member shall be void unless otherwise specifically authorized by this
Agreement. Notwithstanding the foregoing, any Member may Transfer its Units to a
person who is also a Member at the time of such Transfer.

      (b)   Any Transfer of Units shall be effective only to give the person to
whom the Units were Transferred (the "Transferee") the right to receive the
share of tax allocations and distributions to which the person transferring (the
"Transferor") would otherwise be entitled. Except as otherwise provided herein,
no Transferee of Units shall have the right to become a substituted Member
unless approved by the Members who own at least a majority of the then
outstanding Units (excluding the Units involved in the Transfer), and the
Transferee agrees in writing to be bound by all the terms and conditions of this
Agreement as then in effect. Unless and until a Transferee is admitted as a
substituted Member, the Transferee shall have no right to exercise any of the
powers, rights, and privileges of a Member under this Agreement.

                                       15
<PAGE>

      (c)   No Member shall cause or permit to be created a lien or security
interest which affects or might affect its Units, except with the Approval of
the Board of Managers.

      (d)   Each Member agrees not to Transfer all or any part of his Units (or
take or omit any action, filing election, or other action, which could result in
a deemed transfer) if such Transfer (either considered alone or in the aggregate
with prior transfers by other Members) would result in the termination of the
Company for federal income tax purposes. To enable the Members to identify
Transfers which could result in such a termination, each Member covenants and
agrees to inform the Board of Managers prior to any proposed Transfer (or deemed
Transfer for purposes of the Code).

      (e)   Each purported Transfer which does not comply with the provisions of
this Article XI shall be void and of no effect, and shall not be given effect in
the Company's corporate records.

SECTION 11.2 RIGHT OF FIRST REFUSAL.

      (a)   If at any time any Member desires to sell all or any of its Units on
a current or deferred basis pursuant to a bona fide offer from any person other
than another Member (the "Non-Member Buyer"), then such Member (the "Seller")
shall, if the Seller desires to accept such offer, deliver a written offer (the
"Offer") to sell such Units (the "Offered Units") to the Company and the other
Members (the "Other Members" and collectively with the Company, the
"Purchasers") for the consideration and on the terms and conditions not less
favorable to the Purchasers than those on which the Seller proposes to sell such
Offered Units to the Non-Member Buyer. The Offer shall disclose the identity of
the Non-Member Buyer, the Offered Units proposed to be sold, the total Units
owned by the Seller, the material terms and conditions of the Offer (including
price), and any other material facts relating to the proposed sale. The Offer
shall further state that the Purchasers may acquire, in accordance with the
provisions of this Agreement, all but not less than all of the Offered Units for
the price and upon the other terms and conditions, including deferred payment
(if applicable), as set forth therein.

      (b)   Each of the Other Members shall have the absolute right to purchase
that percentage of the Offered Units as shall be equal to the number of Offered
Units multiplied by a fraction, the numerator of which shall be equal to the
number of Units then owned by such Other Member and the denominator of which is
the number of Units then owned by all of the Other Members. The Offered Interest
that each Other Member is entitled to purchase under this Section 11.2(b) shall
be referred to as his "Pro Rata Fraction".

      (c)   The Other Members shall have a "right of oversubscription" such that
if any Other Member fails to accept the Offer as to his Pro Rata Fraction, the
remaining Other Members who have exercised their right to the Pro Rata Fraction
of the Offer shall, among them, have the right to purchase up to the balance of
the Offered Units not so purchased. Such right of oversubscription may be
exercised by any such remaining Other Members by accepting the Offer as to more
than his Pro Rata Fraction. If, as a result thereof, such oversubscriptions
exceed the total Offered Units available in respect of such oversubscription
privilege, the oversubscribing Other Members shall be reduced with respect to
their oversubscriptions on a pro rata basis in

                                       16
<PAGE>

accordance with their respective Pro Rata Fractions or as they may otherwise
agree among themselves.

      (d)   If any Other Member desires to purchase all or any part of the
Offered Units, such Other Member shall notify the Seller, in writing and within
thirty (30) days of its receipt of the Offer, of its election to purchase all or
any party of the Offered Units. Such notice shall, when taken in conjunction
with, the Offer, constitute a valid, legally binding and enforceable agreement
for the sale and purchase of such Offered Units (subject to the aforesaid
limitations as to the right of an Other Member to purchase more than its Pro
Rata Fraction).

      (e)   If the Other Members do not purchase any, or purchase some but not
all, of the Offered Units, then the Company shall have the option, exercisable
within fifteen (15) days after the end of the thirty (30) day period following
the date the Offer was delivered to all of the Other Members, to acquire all but
not less than all of the Offered Units not otherwise acquired by the Other
Members. If the Company desires to acquire such Offered Units, the Company shall
communicate its election to the Seller in writing within the fifteen (15) day
exercise period.

      (f)   Unless otherwise mutually agreed upon by the parties, the closing of
the purchase and sale of the Offered Units to be sold to Purchasers pursuant to
this Section 11.2 shall be made at the offices of the Company on the forty fifth
(45th) day following the date the Offer was delivered to the purchasing
Purchaser of such Units (or if such forty fifth (45th) day is not a business
day, then on the next succeeding business day), At such closing., the purchase
and sale of the Offered Units shall be effected by the Seller's delivery to each
Purchaser of a certificate or certificates evidencing the Offered Units to be
purchased, duly endorsed for transfer to such Purchaser, against payment to the
Seller of the purchase price therefor by such Purchaser.

      (g)   If the Purchasers do not purchase all of the Offered Units, then no
Purchaser shall have any right to purchase any portion of the Offered Units and
the Seller may, sell all, but not less than all, of the Offered Units to the
Non-Member Buyer at any time within thirty (30) days after the earlier to occur
of: (i) the closing date described in Section 11.2(f) above; (ii) the latest
date on which the Purchasers deliver to the Seller notice that they will not
purchase all of the Offered Units; or (iii) the latest date on which the Offer
to the Purchasers has expired and the Purchasers have not exercised their right
to purchase all of the Offered Units. Any such sale shall be to the Non-Member
Buyer at not less than the price and upon other terms and conditions, if any,
not more favorable to the Non-Member Buyer than those specified in the Offer.
Any Offered Units not sold within such thirty (30) day period shall continue to
be subject to the requirements of a prior offer pursuant to this Section 11.2.
As a condition to the sale of the Offered Units to the Non-Member Buyer, the
Non-Member Buyer shall agree in writing to be bound by all of the provisions of
this Agreement to the same extent as if the Non-Member Buyer was a party to this
Agreement, including, without limitation, an acknowledgment that the Offered
Units so sold shall continue to be subject to any of restrictions imposed by
this Agreement

      (h)   If the Non-Member Buyer's written offer (and the Seller's
corresponding Offer to the Purchasers) provides for the payment of consideration
other than cash (herein, "Unique Consideration"), then any Purchaser may, in its
notice of exercise, in lieu of Unique Consideration, substitute cash
consideration which shall be determined by mutual agreement of

                                       17
<PAGE>

the Offerer and such Purchaser within forty (40) days after the Offerer's offer
is made, or, failing such agreement, by arbitration in Miami-Dade County,
Florida, as provided in Section 20.2 below. Any Purchaser's notice of exercise
shall be sufficient if it states that such Purchaser shall pay cash
consideration to be determined in accordance with this Section 11.2(h).

SECTION 11.3 FAILURE TO DELIVER UNITS.

      If a Member becomes obligated to sell any Units under this Agreement and
fails to deliver such Units in accordance with the terms of this Agreement, the
person entitled to acquire such Units may, at its option, in addition to all
other remedies he may have, send to such Member the purchase price for such
Units as is herein specified. Thereupon, the Company upon written notice to the
Member: (a) shall cancel on its books the certificate or certificates
representing the Units to be sold; and (b) shall issue, in lieu thereof, in the
name of such person entitled to acquire such Units, a new certificate or
certificates representing such Units, and thereupon all of the Member's rights
in and to such Units shall terminate.

SECTION 11.6 SUBSTITUTE MEMBERS.

      The assignee of a Unit shall have the right to become a substitute Member
in the Company if (i) the assignor so provides in the instrument of assignment,
(ii) the assignee agrees in writing to be bound by the terms of this Agreement
and the Articles of Organization, as amended to the date thereof, (iii) written
consent to such assignment has been obtained from the other Members entitled to
vote thereon, (iv) the assignee pays the reasonable costs incurred by the
Company in preparing and recording any necessary amendments to this Agreement
and the Articles of Organization, and (v) the assignor and assignee otherwise
agree to be bound by the terms of the Act, and (vi) assignor and assignee shall
perform such other acts as the Members deem reasonably necessary for the benefit
of the Company.

of the following events:

            (i)   The Member dies (or, if the member is an entity, it incurs a
dissolution or equivalent event);

            (ii) The Member incurs a physical or mental disability, whereby the

            (iii) The Member becomes bankrupt or insolvent;

            (iv) The member voluntary renounces its right to participate in the
business and internal affairs of the company. A Member may resign as a Member of

resignation shall be effective ninety days after all of the other Members have
received the notice; or

                                       18
<PAGE>

            (v) The Member transfers all of the Member's Units to another
Person, in accordance with the terms of this Agreement.

      (b)   Except as provided in this Section 11.7(b) and as otherwise provided
in this Agreement, a Member's withdrawal shall not entitle the Member to receive
any distribution of Company profits or other assets or to receive any payment
for the Member's Units. Notwithstanding the foregoing, upon withdrawal of a
Member, the other Members of the Company shall have the right to: (i) dissolve
the Company in accordance with Section 12 hereof; or (ii) repay to the
withdrawing Member, within a reasonable time after withdrawal, the positive
account balance, if any, in the withdrawing Member's Capital Account.

the Company shall continue notwithstanding the occurrence of the Dissociation
Event. Each party hereto hereby consents to and agrees that (a) the business and
existence of the Company shall continue notwithstanding the occurrence of a
Dissociation Event, and (b) it is their intent that the provisions of this
