Loan shall be evidenced by its promissory note payable to the order of
CommScope Optical Technologies, Inc. (the "Revolving Note") in

incurs Indebtedness from Furukawa or its Affiliates in an amount of
$120,000,000 or less, such Indebtedness will be incurred on terms and
conditions that with respect to interest, repayment, prepayment, Events of
Default, priority and security are no more favorable to Furukawa and its
Affiliates than provided herein to Lender.

     3.2 Mandatory Prepayment. The Borrower shall prepay the outstanding
principal amount of the Revolving Loan together with any accrued interest

exercising the right to sell Membership Interests (as defined in the MOU)
in the Borrower held by CommScope and its Affiliates pursuant to Section

provided herein, all payments under this Agreement or the Revolving Note

at the applicable rate during such extension.

     3.5 Pro Rata Treatment with Furukawa. If Borrower, or any of its
Subsidiaries, makes a payment or prepayment of principal on any
Indebtedness owed to Furukawa or any of its Affiliates, the Borrower or its
Subsidiaries, shall simultaneously prepay any amounts outstanding hereunder
or under the Revolving Note in an amount proportionate to such payment or
prepayment to Furukawa or any of its Affiliates, based on the relative
amount of Indebtedness owed by the Borrower and its Subsidiaries to
CommScope and its Affiliates, and Furukawa and its Affiliates,
respectively; provided, however, if the Borrower incurs Indebtedness from
Furukawa and its Affiliates in excess of $120,000,000, such excess may be

                  of Managers in proportion to its Membership Interest,
                  rounded down to the nearest whole number of Managers,

                  exceeds 5% (each such Manager, a "COMMSCOPE OPTICAL
                  DESIGNEE"); and

            (ii)  Fitel USA shall be entitled to designate the remaining

     4.6 Regular Meetings. The Board of Managers shall hold regular
meetings at least once each fiscal quarter, at the principal offices of the
Company or at such other place as may be determined by the Chief Executive

meeting shall be given to each Manager by telecopy or similar method or
sent by reputable overnight delivery service, in each case at least five
Business Days before the meeting, unless a longer notice period is
established by the Board of Managers. Any Manager may waive notice of, or
the taking of any action at, any meeting in writing before, at, or after
such meeting. The attendance of a Manager at a meeting shall constitute a
waiver of notice of such meeting, except when a Manager attends a meeting
for the express purpose of objecting to the transaction of any business
because the meeting was not properly called.

     4.7 Special Meetings. Special meetings of the Board of Managers may be
called by any two Managers. The call shall be in writing and shall state
the location of the meeting and the nature of the business to be
transacted. Notice of each such meeting shall be given to each Manager by
telecopy or similar method or sent by reputable overnight delivery service,
in each case at least three calendar days before the meeting, unless a
longer notice period is established by the Board of Managers. Any Manager
may waive notice of, or the taking of any action at, any meeting in writing
before, at, or after such meeting. The attendance of a Manager at a meeting
shall constitute a waiver of notice of such meeting, except when a Manager
attends a meeting for the express purpose of objecting to the transaction
of any business because the meeting was not properly called.

of the Board of Managers, or any action that may be taken at a meeting of
the Board of Managers, may be taken at a meeting held by means of
conference telephone or other communications equipment by means of which
all persons participating in the meeting can hear each other. Participation
in such a meeting shall constitute presence in person at such meeting. The
Company shall permit any Manager or proxy of any Manager to participate by
conference telephone.

     4.9 Written Consent. Notwithstanding anything to the contrary in this
Agreement, the Board of Managers may without a meeting take any action that
may be taken by the Board of Managers under this Agreement if such action
is approved by the written consent of that number of Managers otherwise
required for action by the Board of Managers (but not less than the number
of Managers as shall equal a quorum) and prior written notice of such
action is given to each of the Members (or waived in writing by each
Member). Notice of such action shall be

                                    13

<PAGE>

given to each Manager by telecopy or similar method or sent by reputable
overnight delivery service.

     4.10 Removal of Managers. A Manager may be removed at any time, with
or without cause, by the written notice of the Member that designated such
Manager, delivered to the Company and the other Members, demanding such
removal. Upon the Company's receipt of such written notice, such Manager
shall be automatically removed without further action. The Member that
removed such Manager shall promptly designate a successor to such Manager;
provided that its failure to do so shall not affect any removal effected
thereunder or the ability of the Board of Managers to meet or take any
action. If at any time a Member ceases to be a Member (or becomes a
Suspended Member), any Manager designated by such Member shall be
automatically removed without further action.

     4.11 Resignation of Managers. Any Manager may resign at any time by
giving written notice of his resignation to the Company. Such resignation
shall take effect at the time specified therein, or if no time is
specified, at the time of its receipt by the Company. In the event any
Manager resigns or is unable to serve on the Board of Managers, the Member
that designated such Manager shall promptly designate a successor to such
Manager (subject to Section 4.19(c)); provided that its failure to do so
shall not affect any resignation effected thereunder or the ability of the
Board of Managers to meet or take any action.

     4.12 Delegation of Manager's Powers; Officers. The Board of Managers
shall have the right to delegate its authority by the same vote of the
Board of Managers as would be required for the Board of Managers to take
such action, to the extent provided in this Agreement, to Officers of the
Company, to assist with the management of the business affairs of the
Company. The Officers of the Company shall consist of a Chief Executive
Officer, a Chief Financial Officer, a Secretary and one or more Vice
Presidents. Any two or more offices may be held by the same person. The
Officers of the Company shall report to the Chief Executive Officer unless
the Board of Managers directs an Officer to report directly to the Board of
Managers.

     4.13 Resignation and Removal of Officers. An Officer may resign at any
time by giving written notice to the Board of Managers or the Chief
Executive Officer. A resignation is effective when it is received unless it
specifies a later date. Officers may be removed at any time, with or
without cause, by the Board of Managers. In the event any Officer resigns,
is removed or is unable to serve as an Officer, the Board of Managers shall
promptly designate a successor to such Officer.

     4.14 Chief Executive Officer. The Chief Executive Officer of the
Company shall have the powers and duties of supervision and management
usually vested in the chief executive officer of a company. The Chief
Executive Officer may sign, alone or with any of the Vice-Presidents or any
other proper Officer of the Company thereunto authorized by the Board of
Managers, any deeds, mortgages, bonds, contracts or other instruments which
the Board of Managers has authorized to be executed, except in cases where
the signing and execution thereof shall be expressly delegated by the Board
of Managers or by this Agreement to some other Officer or agent of the
Company, or shall be required by law to be otherwise signed or executed,

                                    14

<PAGE>

and in general he or she shall perform all duties incident to the office of
the Chief Executive Officer and other duties from time to time may be
prescribed by the Board of Managers.

     4.15 Other Officers. The other Officers of the Company shall have such
powers and duties as may be delegated to such Officers by the Board of
Managers.

     4.16 Limitations on Power of Board of Managers. The enumeration of
powers in this Agreement shall not limit the general or implied powers of
the Board of Managers or any additional powers provided by law.
Notwithstanding the foregoing and any other provision contained in this
Agreement to the contrary, the Company shall not, and shall not permit its
Subsidiaries to (the "MAJOR DECISIONS"):

     (a)  take any action in contravention of, amend, modify or waive, the
          provisions of this Agreement or the Certificate in a manner (i)
          adverse to any Member's rights under this Agreement or the
          Certificate without the consent of any such Member then owning
          (together with its Affiliates) 10% or more of the fully-diluted
          Membership Interests then outstanding or (ii) materially adverse
          to any Member's rights under this Agreement or the Certificate
          without the consent of any such Member then owning (together with
          its Affiliates) 5% or more of the fully-diluted Membership
          Interests then outstanding; or

     (b)  take any action that would constitute a Bankruptcy Event with
          respect to the Company without the consent of each Member then
          owning (together with its Affiliates) 10% or more of the
          fully-diluted Membership Interests then outstanding, or if
          CommScope and its Affiliates own less than 10% of the
          fully-diluted Membership Interests then outstanding, take any
          action that would constitute a Bankruptcy Event with respect to
          the Company without the consent of CommScope Optical if such
          action would cause CommScope's right to sell the Membership
          Interests held by it and its Affiliates under Section 5.6 of the
          MOU to become unenforceable or incapable of being exercised.

     4.17 Subsidiaries. The provisions of this Agreement relating to the
management and control of the business and affairs of the Company, and the
respective rights and duties of, and restrictions on, the Board of
Managers, Officers and the other Members, shall also be construed to be
fully applicable to the management and control of any Subsidiary of the
Company. In illustration and not in limitation of the foregoing, with
respect to any such Subsidiary of the Company, the provisions of this
Agreement relating to the respective rights and duties of, and restrictions
on, the Board of Managers, the Officers and the other Members with respect
to the management and control of the Company and its business shall be
equally applicable to the management and control of such Subsidiary.

     4.18 Standard of Care; Fiduciary Duty. No Member or Manager of the
Company shall owe any fiduciary duty, other than the duty of a Manager to
act with the care of a reasonably prudent person, to the Company, any
Affiliate of the Company, any Member or any Affiliate of any of the
foregoing. No Member shall have any claim against any other Member, any
Manager or any Affiliate of any of the foregoing, based upon or arising
from a claimed breach of a fiduciary duty, duty of loyalty, corporate
opportunity doctrine, conflict of interest or any similar

                                    15

<PAGE>

basis, and each Member hereby waives any such claim on behalf of itself and
its Subsidiaries and Affiliates. In taking any action, making any decision
or exercising any discretion with respect to the Company or its
Subsidiaries, a Manager or Member shall be entitled to consider such
interests and factors as it desires, including its own interests or those
of its Affiliates, and shall have no duty or obligation (a) to give any
consideration to the interest of or factors affecting the Company or any
other Person or (b) to abstain from participating in any vote or other
action of the Company, any Subsidiary or Affiliate of the Company, the
Board of Managers, or any board of directors or similar governing body of
any of the foregoing. Nothing contained in this Section 4.18 shall
constitute a waiver of any claim for breach of this Agreement by any
Member.

     4.19 CommScope Optical Designees. (a) CommScope Optical shall, and
shall ensure that CommScope Optical's Affiliates, implement measures to
prevent the CommScope Optical Designees (i) from receiving from CommScope
Optical or any Affiliate of CommScope Optical (collectively the "COMMSCOPE
ENTITIES") and (ii) from providing to any of the CommScope Entities, any
information that may be competitively sensitive with respect to any
competition between any of the CommScope Entities and the Company,
including without limitation any information containing pricing, markets,
customers, prospects, strategic planning, methods of operations, or
employees of any of the CommScope Entities with respect to areas where any
of the CommScope Entities competes with the Company; provided, however,
that nothing in this Section 4.19 is intended to limit any right of
CommScope set forth herein to obtain information necessary to protect and
evaluate CommScope's investment in the Company.

          (b) CommScope Optical shall indemnify and hold harmless the
Company, each Member and any Affiliate of any Member from any Losses and
Expenses arising from (i) CommScope Optical's breach of this Section 4.19
or (ii) any federal, state or foreign antitrust law resulting from the
participation of any CommScope Optical Designee in the affairs of the
Company or any Subsidiary of the Company.

          (c) Notwithstanding anything contained herein to the contrary,
the Majority Member shall have the right to (i) consent to the designation
of the person designated as the CommScope Optical Designee or (ii) to
remove as a Manager, at any time, the person designated as the CommScope
Optical Designee, in each case, if the Majority Member determines, after
consultation with counsel, that the identity of such person could create a
risk of non-compliance with any antitrust or competition law. No person
designated by CommScope Optical shall become a Manager of the Company prior
to the receipt by the Company and CommScope Optical of the Majority
Member's written notice of consent to the designation of such person as a
CommScope Optical Designee pursuant to clause (i) above. If the written
notice of consent is not delivered to CommScope Optical within ten Business
Days of CommScope Optical's written notice to the Majority Member of the
identity of its designee, the Majority Member shall be deemed to have
consented to such person for purposes of clause (i) above. Upon the
delivery of a written notice of removal, pursuant to clause (ii) above, to
the Company or CommScope Optical with respect to any person designated as a
CommScope Optical Designee, such person shall automatically cease to be a
Manager without further action and CommScope Optical shall promptly
designate a replacement Manager (subject to clause (i) above).

ARTICLE 5.    MEMBERS

     5.1 Liability of Members. Subject to the provisions of the LLC Act,
the debts, obligations and liabilities of the Company shall be solely the
debts, obligations and liabilities of the Company, and the Members shall
not be obligated personally for any such debt, obligation or liability of
the Company solely by reason of being a Member. The failure of the Company
to observe any formalities or requirements relating to the exercise of its
powers or management of its business or affairs under the LLC Act or this
Agreement shall not be grounds for imposing personal liability on a Member
for any liabilities of the Company.

     5.2 Authority of Members. Except as set forth in Section 4.16 hereof,
the Members shall not have any right or power to take part in the
management or control of the Company or its business and affairs or to act
for or bind the Company in any way. Notwithstanding the foregoing, the
Members have all the rights and powers specifically set forth in this
Agreement and, to the extent not inconsistent with this Agreement, in the
LLC Act.

     5.3 Voting. No Member has any voting right except with respect to
those matters specifically set forth in this Agreement and as required in
the LLC Act.

     5.4 Preemptive Rights. If the Company proposes to issue any Membership
Interest, warrants, options or rights to purchase any Membership Interest,
any security which is or may be convertible into a Membership Interest or
any other equity security of the Company or calls for additional Capital
Contributions, regardless of form (each a "COMPANY SECURITY"), other than
an Exempt Issuance, the Company shall, prior to such issuance, deliver to
each Member a written notice (the "PREEMPTION NOTICE") thereof describing
the terms and conditions of such issuance (the "PREEMPTION NOTICE
TRANSACTION"). Such Members, by giving written notice to the Company not
later than five (5) Business Days following the giving of the Preemption
Notice, may participate as purchasers in the Preemptive Notice Transaction
on a pro rata basis based on the proportion of such Member's Membership
Interest relative to the amount of outstanding Membership Interests on a
fully-diluted basis. The participating Members shall participate as a
purchaser in such Preemption Notice Transaction for a price per Company
Security equal to the price per Company Security being paid to the Company
in such issuance and on the same terms and conditions as those applicable
to the proposed purchaser in such Preemption Notice Transaction. The number
of Company Securities to be issued by the Company to the proposed purchaser
in such issuance shall be reduced by the number of Company Securities that
the participating Members purchase pursuant to this Section 5.4. To the
extent that any Member receiving the Preemption Notice does not accept the
offer to participate in the Preemption Notice Transaction, the Company may
issue such Company Securities to another Person on terms no less favorable
to the Company than the terms set forth in such Preemption Notice. The
right of Members to participate in the Preemption Notice Transaction is
conditioned on the consummation of such Preemption Notice Transaction.

ARTICLE 6.    TRANSFERS AND REPURCHASES OF MEMBERSHIP INTERESTS

     6.1 Transfer Restrictions. (a) For three years from the date hereof
(the "RESTRICTION PERIOD"), no Direct Transfer shall be effected without
the prior consent of the Board of

                                    17

<PAGE>

Managers (other than, in the case of CommScope Optical or its Affiliates, a
Direct Transfer to Furukawa or its Affiliates; provided that a Member may
Direct Transfer all or part of its Membership Interest to one or more of
its wholly owned Subsidiaries at any time (a "SUBSIDIARY TRANSFER").

          (b) At no time may any Direct Transfer of any Membership Interest
be made to any Person (i) then listed in Appendix A to the Corning Patent
License or (ii) engaged in the cable and/or fiber optics business (other
than Furukawa or any Subsidiary of Furukawa) and headquartered in Japan
(any such person described in clauses (i) or (ii), a "RESTRICTED
TRANSFEREE") without the consent of the Board of Managers.

          (c) In the event that, without the prior approval of the Board of
Manager, (i) a CTV Member Transfer is effected prior to the expiration of
the Restriction Period or (ii) any CTV Member Transfer is entered into with
a Restricted Transferee (any transaction described in clause (i) or (ii), a
"SUSPENSION TRANSACTION"), the Member who engaged, or whose Affiliate
engaged, in such transaction (the "SUSPENDED MEMBER") shall not be
permitted to exercise any rights or privileges hereunder, all rights and
privileges hereunder of such Suspended Member with respect to its
Membership Interest shall be unenforceable and any Manager designated by
such Suspended Member shall be automatically removed from the Board of
Managers without any further action; provided that such Suspended Member
shall not be relieved of any of its obligations arising under this
Agreement; provided, further, that such Suspended Member shall be permitted
to receive, subject to applicable antitrust and other competition laws and
to the confidentiality provisions set forth in Section 12.4, such
information as is necessary for such Suspended Member to monitor any
determination of the Fair Market Value of such Suspended Member's
Membership Interest hereunder. A Suspended Member shall cease to be a
Suspended Member, and thereafter all rights and privileges of such
Suspended Member as a Member shall be restored, upon the rescission,
unwinding or undoing of the transaction that resulted in such Member
becoming a Suspended Member.

          (d) All Direct Transfers, other than Subsidiary Transfers, must
be made for cash and in compliance with all applicable securities laws. Any
purported Direct Transfer in violation of applicable securities laws or
this Article 6 shall be void ab initio, and shall not bind the Company, and
the Member making such purported Direct Transfer shall indemnify and hold
the Company and the other Members harmless from and against any federal,
state, or local income taxes, or transfer taxes, including transfer gains
taxes, and any other liability arising as a result of, or caused directly
or indirectly by, such purported Direct Transfer. A Member shall not be
relieved of any of its obligations arising under this Agreement prior to
any Direct Transfer effected by such Member, and such Member and any
transferee shall execute such documents as the Company and/or such other
Members shall reasonably request to evidence the Transfer and the
assumption and continuing obligations under this Agreement.

     6.2 Right of First Refusal. (a) In the event that following the
Restriction Period any Minority Member or Affiliate thereof (collectively,
the "TRANSFERRING MEMBER") has received a bona fide written offer from a
Person other than a Restricted Transferee, which such Transferring Member
is willing to accept, for the Transferring Member to Direct Transfer all,
but not less than all, of its Membership Interest (the "TRANSFERRED
INTEREST"), such Transferring Member shall deliver a written notice (the
"TRANSFER NOTICE") to all of the other Members (the "NON-

                                    18

<PAGE>

TRANSFERRING MEMBERS") stating the Transferring Member's intent to Direct
Transfer the Transferred Interest pursuant to such bona fide offer. The
Transfer Notice shall (i) specify the purchase price for and other material
terms with respect to the Direct Transfer, (ii) identify the proposed
purchaser of the Transferred Interest and (iii) specify the date scheduled
for the Direct Transfer.

          (b) The Non-Transferring Members shall have the exclusive option
to purchase all, but not less than all, of the Transferred Interest on
terms and conditions substantially the same in all material respects as set
forth in the written offer delivered pursuant to subsection (a) above, but
at a price no less than that specified in the Transfer Notice; provided
that no Non-Transferring Member shall be required to pay more than Fair
Market Value for such Transferred Interest. The Non-Transferring Members
shall notify the Company and the Transferring Member of their intention to
exercise or not to exercise the right of first refusal hereunder within
forty-five (45) calendar days of receipt by the Non-Transferring Member of
a Transfer Notice.

          (c) In the event that a Non-Transferring Member elects to
purchase the Transferred Interest (an "ELECTING MEMBER"), the Electing
Member and the Transferring Member shall diligently pursue obtaining all
regulatory approvals and use reasonable best efforts to consummate the
closing of the purchase of the Transferred Interest as soon as practicable
and in any event within 100 calendar days from receipt of the Transfer
Notice; provided that, if such closing does not occur within such 100
calendar day period due to the failure to obtain any required regulatory
approvals, the Electing Member's right to close such sale may be extended
at the option of the Electing Member, until such regulatory approvals are
obtained, but in no event for a period of greater than 100 additional
calendar days. In the event of a failure of the Non-Transferring Member to
elect to purchase all of the Transferred Interest or a failure of the
Electing Member to consummate such purchase in accordance herewith, the
Transferring Member will be free, at any time within 120 calendar days from
the date all Non-Transferring Members elect not to exercise their purchase
rights hereunder or from the date the time periods specified in this
section for such election have expired, subject, in each case, to extension
for up to an additional 120 calendar days to the extent necessary to
achieve any required regulatory approvals, to consummate the sale of the
Transferred Interest to the purchaser at a price and upon terms and
conditions no more favorable to the purchaser than those specified in the
Transfer Notice; provided that such Direct Transfer shall remain otherwise
subject to the provisions of this Article 6.

          (d) At the closing of any proposed Transfer in respect of which a
Transfer Notice has been delivered, the Transferring Member shall deliver,
free and clear of all liens (other than this Agreement), to the Electing
Members the Membership Interests elected to be purchased by such Electing
Members and shall receive in exchange therefor the consideration to be paid
or delivered by such Electing Members in respect of such Membership
Interests as described in the Transfer Notice.

     6.3 Tag-Along Rights. (a) In the event that (i) Majority Member
desires to Direct Transfer any Membership Interest or (ii) an Affiliate of
the Majority Member desires to transfer, sell, assign or offer 10% or more
of the voting stock of (x) any Person whose assets consist exclusively or
substantially in their entirety of Membership Interests or (y) any Person
whose

                                    19

<PAGE>

assets consist exclusively or substantially in their entirety of any Person
described in clause (x) above (any transaction described in clause (i) or
(ii) above, a "TAG-ALONG Transfer"), the Majority Member or Affiliate of
the Majority Member proposing to effect the Tag-Along Transfer (the
"TAG-ALONG INITIATOR") shall give written notice of such intended Tag-Along
Transfer to each other Member (each, a "TAG-ALONG OFFEREE") and to the
Company. Such notice (the "TAG-ALONG NOTICE") shall set forth the terms and
conditions of such proposed Tag-Along Transfer, including the name of the
proposed transferee, the amount of Membership Interests proposed to be
Tag-Along Transferred by the Tag-Along Initiator (the "TAG-ALONG
INTERESTS"), the purchase price of Membership Interests proposed to be paid
therefor or allocated thereto in good faith and the payment terms and type
of Tag-Along Transfer to be effectuated. Each Tag-Along Offeree shall, by
written notice to the Tag-Along Initiator and the Company delivered no
later than 14 calendar days after delivery of the Tag-Along Notice by the
Tag-Along Initiator to each Tag-Along Offeree and the Company, have the
opportunity and right to sell to the transferee in such proposed Tag-Along
Transfer (upon the same terms and conditions, or, in the case of a
Tag-Along Transfer that is not a Direct Transfer, on substantially
equivalent terms and conditions, as the Tag-Along Initiator) up to that
amount of Membership Interests owned by the Tag-Along Offeree equal to the
product of (x) a fraction, the numerator of which is the number of
Membership Units owned as of such date by that Tag-Along Offeree and the
denominator of which is the aggregate number of Membership Units owned as
of such date by the Tag-Along Initiator and each Tag-Along Offeree that has
accepted the opportunity to participate and (y) the aggregate number of
Tag-Along Interests. The amount of Tag-Along Interests to be sold by any
Tag-Along Initiator shall be proportionately reduced to the extent
necessary to provide for such sales of Membership Interests hereunder by
Tag-Along Offerees. Notwithstanding anything contained herein to the
contrary, no Member that is not a Tag-Along Offeree shall have any rights
under this Section 6.3.

          (b) At the closing of any proposed Transfer in respect of which a
Tag-Along Notice has been delivered, the Tag-Along Initiator together with
all Tag-Along Offerees electing to sell Membership Interests, shall
deliver, free and clear of all liens (other than this Agreement), to the
proposed transferee the Membership Interests to be sold and shall receive
in exchange therefor the consideration to be paid or delivered by the
proposed transferee in respect of such Membership Interests as described in
the Tag-Along Notice.

     6.4 Take-Along Rights. A Majority Member desiring to Direct Transfer
(other than in a Subsidiary Transfer or a Direct Transfer to an Affiliate
of the Majority Member) all, but not less than all, of the Membership
Interests owned by it and its Affiliates (the "TAKE-ALONG INITIATOR") shall
give written notice of such intended Transfer to each other Member (each, a
"TAKE-ALONG OFFEREE") and to the Company. Such notice (the "TAKE-ALONG
NOTICE") shall set forth the terms and conditions of such proposed
Transfer, including the name of the proposed transferee, the purchase price
proposed to be paid for such Membership Interests and the payment terms and
type of Transfer to be effectuated. The Take-Along Initiator shall have the
right, exercisable not later than 14 calendar days after delivery of the
Take-Along Notice, to require each Take-Along Offeree to sell to the
transferee in such proposed Transfer (upon the same terms and conditions as
the Take-Along Initiator, including with respect to price and form of
consideration) all of such Take-Along Offeree's Membership Interests.

                                    20

<PAGE>

          (b) At the closing of any proposed Transfer in respect of which a
Take-Along Notice has been delivered, the Take-Along Initiator together
with all Take-Along Offerees electing to sell Membership Interests, shall
deliver, free and clear of all liens (other than this Agreement), to the
proposed transferee the Membership Interests to be sold and shall receive
in exchange therefor the consideration to be paid or delivered by the
proposed transferee in respect of such Membership Interests as described in
the Take-Along Notice.

     6.5 Assignment Binding on Company. No Direct Transfer of all or any
part of the Membership Interest of a Member permitted to be made under this
Agreement shall be binding upon the Company unless and until a duplicate
original of such instrument of Direct Transfer, duly executed and
acknowledged by the assignor or transferor and assignee or transferee (the
"SUBSTITUTE MEMBER"), has been delivered to the Company, and such
instrument evidences (i) the written acceptance by each Substitute Member
of all of the terms and provisions of this Agreement and (ii) each
Substitute Member's representation that such Direct Transfer was made in
accordance with all applicable laws and regulations and the terms and
provisions of this Agreement.

     6.6 Substituted Members. Members who Direct Transfer all their
Membership Interests pursuant to a Direct Transfer permitted under this
Agreement shall cease to be Members of the Company except that unless and
until a Substituted Member is admitted in its stead, the Direct
Transferring Member shall not cease to be a Member of the Company under the
LLC Act and hereunder. Notwithstanding Section 6.5, any Person who is an
assignee or transferee of any Membership Interest of a Member and who has
satisfied the requirements of Article 6 shall become a Substituted Member
only when (i) the Board of Managers has entered such Person as a Member on
the books and records of the Company, which the Board of Managers is hereby
directed to do upon satisfaction of such requirements, and (ii) such Person
shall have paid all reasonable legal fees and filing costs in connection
with the substitution as a Member.

     6.7 Acceptance of Prior Acts. Any person who becomes a Member, by
becoming a Member, accepts, ratifies and agrees to be bound by all actions
duly taken pursuant to the terms and provisions of this Agreement by the
Company prior to the date it became a Member and, without limiting the
generality of the foregoing, specifically ratifies and approves all
agreements and other instruments as may have been executed and delivered on
behalf of the Company and which were in force and effect prior to the date
it became a Member.

     6.8 Admission of Transferees to the Company. If the foregoing
provisions of this Article 6 have been observed, an assignee or transferee
of Membership Interests shall be admitted to the Company and shall have all
other rights and obligations of a Member hereunder.

     6.9 Right to Call Membership Interests

          (a) In the event that any Member (together with its Affiliates)
owns 5% or less than the fully-diluted Membership Interests then
outstanding, the Company shall have the right to purchase by written notice
to the Member all, but not less than all, of such Member's (and its
Affiliates') Membership Interest for an amount in cash equal to the Fair
Market Value of such Membership Interest at the time notice of such
exercise is given, and such notice, once given, shall be irrevocable;
provided that the Company shall not exercise such right to purchase any

                                    21

<PAGE>

Membership Interest held by CommScope Optical or its Affiliates prior to
the expiration of the Exercise Period and, in any event, only if CommScope
does not timely exercise the right to sell Membership Interests in
accordance with Section 5.6 of the MOU.

          (b) In the event of any CTV Member Transfer or Change of Control
of CommScope (each, a "CALL TRANSACTION"), the Company shall have the right
to purchase all, but not less than all, of the Membership Interest of any
Member whose Affiliate entered into the Call Transaction (each, a "CALL
TRANSACTION MEMBER"). Upon the execution of any agreement by any Affiliate
of a Member to enter into a Call Transaction, each Call Transaction Member
shall deliver prompt written notice to the Company that it has entered into
a Call Transaction (a "CALL TRANSACTION NOTICE"). The Call Transaction
Notice shall (i) specify the type of transaction proposed to be effected by
the Call Transaction, (ii) identify the proposed parties to such Call
Transaction and (iii) specify the date scheduled to effect the Call
Transaction. The Company shall have the option (subject to consummation of
the Call Transaction in the event of a Change of Control of CommScope) to
purchase all, but not less than all, of the Call Transaction Member's (and
its Affiliates') Membership Interest for an amount in cash equal to the
then Fair Market Value of such Membership Interest. The Company shall
exercise its option to purchase such Membership Interests by delivering a
notice of exercise to the Call Transaction Member within forty-five (45)
calendar days of receipt by the Company of a Call Transaction Notice. In
the event that the Company elects to exercise its option to purchase the
Membership Interest of the Call Transaction Member, (i) the Company shall
deliver to the Call Transaction Member the purchase price for such
Membership Interests within 100 calendar days of the determination of the
Fair Market Value for such Membership Interests (such date, the "PAYMENT
DATE") and (ii) during the period, if any, commencing on the consummation
of the Call Transaction and ending on the earlier of (A) the consummation
of the purchase by the Company of the Call Transaction Member's Membership
Interest and (B) the Payment Date, the Call Transaction Member shall be
deemed to be a Suspended Member.

          (c) In addition to, and not in limitation of, Section 6.9(b), if,
at any time that CommScope and its Affiliates own 15% or more of the
Membership Interests (whether calculated on a then actually outstanding or
a fully-diluted basis), any entity listed on Appendix A to the Corning
Patent License either (i) acquires, directly or indirectly, a 20% or
greater equity interest in CommScope, or (ii) acquires, directly or
indirectly, Corning Defined Control of CommScope (an "APPENDIX A
TRANSACTION") then the Company (or the Majority Member or an Affiliate of
the Majority Member) shall have the right, by notice to CommScope Optical
(an "EXERCISE NOTICE"), to purchase from any CommScope Entity then owning
Membership Interests, that amount of Membership Interests sufficient to
reduce the CommScope Entities' collective ownership to 14.9% of the
Membership Interests then actually outstanding or on a fully-diluted basis
(whichever method would result in the CommScope Entities having the smaller
aggregate ownership interest in the Company and its Subsidiaries), for a
purchase price equal to 80% of the then Fair Market Value of such
Membership Interests. The CommScope Entities shall give prompt written
notice (but in no event later than one calendar day after the event giving
rise to the obligation to give such notice) to the Company and the Majority
Member (i) of an agreement with respect to an Appendix A Transaction, or,
if no such agreement is entered into, upon consummation of an Appendix A
Transaction or (ii) of any public filing with the U.S. Securities and
Exchange Commission by any Person indicating the intention of such Person
to commence or consummate an Appendix A Transaction. If the Company (or the

                                    22

<PAGE>

Majority Member or an Affiliate of the Majority Member) delivers an
Exercise Notice, the Company (or the Majority Member or an Affiliate of the
Majority Member) and the CommScope Entities shall consummate the purchase
of CommScope Entity Membership Interests contemplated by this Section
6.9(c) within the time period set forth in Section 2.04 of the Corning
Patent License within which Corning may not exercise its right to terminate
the licenses to Fitel USA and/or its Affiliates thereunder. The Company (or
the Majority Member or an Affiliate of the Majority Member) and the
CommScope Entities agree that, to the extent that such purchase cannot be
consummated within the time period set forth above, the parties shall enter
into such escrow, trust or other arrangements as are necessary to avoid,
pending consummation of such purchase, Corning's termination right under
Section 2.04 of the Corning Patent License. Fitel USA shall give CommScope
Optical and its Affiliates prompt notice of any amendment, modification or
waiver of the Corning Patent License, including Appendix A thereto, that
could reasonably affect CommScope Optical's and its Affiliates' obligations
hereunder.

          (d) Upon the consummation of a purchase by the Company of any
Membership Interest pursuant to this Section 6.9, the Member Direct
Transferring such Membership Interests shall deliver, free and clear of all
liens (other than this Agreement), to the Company the Membership Interests
elected to be purchased by Company and shall receive in exchange therefor
the consideration to be paid or delivered by the Company in respect of such
Membership Interests as described above.

     6.10 Right to Put Membership Interests. In the event of any Change of
Control of Fitel USA (an "EXIT TRANSACTION"), each Minority Member shall
have the right to sell all, but not less than all, of such Minority
Member's Membership Interest to the Company. Upon the execution of any
agreement by the Majority Member to enter into an Exit Transaction, the
Majority Member shall deliver prompt written notice to the Company and each
Minority Member that it has entered into an Exit Transaction (an "EXIT
TRANSACTION NOTICE"). The Exit Transaction Notice shall (i) specify the
type of transaction proposed to be effected by the Exit Transaction, (ii)
identify the proposed parties to such Exit Transaction and (iii) specify
the date scheduled to effect the Exit Transaction. Each Minority Member
shall have the option (subject to consummation of the Exit Transaction) to
sell all, but not less than all, of the Minority Member's Membership
Interest to the Company for an amount in cash equal to the then Fair Market
Value of such Membership Interest. A Minority Member shall exercise its
option to sell such Membership Interests by delivering a notice of exercise
to the Company within forty-five (45) calendar days of receipt by the
Majority Member of an Exit Transaction Notice. In the event that a Minority
Member elects to exercise its option to sell its Membership Interest to the
Company, (i) the Company shall deliver to such Minority Member the purchase
price for such Membership Interests within 100 calendar days of the
determination of the Fair Market Value for such Membership Interests (such
date, the "EXIT PAYMENT DATE") and (ii) during the period, if any,
commencing on the consummation of the Exit Transaction and ending on the
earlier of (A) the consummation of the purchase by the Company of such
exercising Minority Member's Membership Interest and (B) the Exit Payment
Date, such Minority Member shall be deemed to be a Suspended Member. Upon
the consummation of a purchase by the Company of any Membership Interest
pursuant to this Section 6.10, the Minority Member Direct Transferring such
Membership Interests to the Company shall deliver, free and clear of all
liens (other than this Agreement), to the Company the Membership Interests
purchased by the Company and shall

                                    23

<PAGE>

receive in exchange therefor the consideration to be paid or delivered by
the Company in respect of such Membership Interests as described above.

     6.11 Securities Laws. The Membership Units have not been registered
under the Securities Act, and, therefore, in addition to the other
restrictions on transfer contained in this Agreement, no Membership Units
or Membership Interest may be sold unless registered under the Securities
Act or an exemption from such registration is then available. Any
certificate (if any) evidencing Membership Units or any Membership Interest
and each certificate issued in exchange for or upon the Transfer of any
Membership Units or Membership Interest shall be stamped or otherwise
imprinted with a legend in substantially the following form:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY ISSUED
     ON NOVEMBER __, 2001 AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
     ACT OF 1933, AS AMENDED (THE "ACT"), AND THE ISSUER (THE "COMPANY")
     HAS NOT BEEN REGISTERED UNDER THE U.S. INVESTMENT COMPANY ACT OF 1940,
     AS AMENDED (THE "INVESTMENT COMPANY ACT"). THE SECURITIES REPRESENTED
     BY THIS CERTIFICATE MAY NOT BE SOLD OR TRANSFERRED (X) IN THE ABSENCE
     OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR IN THE ABSENCE
     OF AN EXEMPTION FROM REGISTRATION THEREUNDER, OR (Y) IF SUCH SALE OR
     TRANSFER CANNOT BE EFFECTED WITHOUT THE LOSS BY THE COMPANY OF ANY
     APPLICABLE INVESTMENT COMPANY ACT EXEMPTION. THE SECURITIES
     REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL
     RESTRICTIONS ON TRANSFER SPECIFIED IN THE LIMITED LIABILITY COMPANY
     AGREEMENT, DATED AS OF NOVEMBER __, 2001, AS AMENDED AND MODIFIED FROM
     TIME TO TIME. THE COMPANY RESERVES THE RIGHT TO REFUSE THE TRANSFER OF
     SUCH SECURITIES UNTIL SUCH CONDITIONS HAVE BEEN FULFILLED WITH RESPECT
     TO SUCH TRANSFER. A COPY OF SUCH CONDITIONS SHALL BE FURNISHED BY THE
     COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST AND WITHOUT CHARGE."

The legend set forth above shall be removed from the certificates (if any)
evidencing any Membership Units or any Membership Interest which ceases to
be a Membership Unit or Membership Interest in accordance with the
definitions thereof.

ARTICLE 7.    CAPITAL CONTRIBUTIONS, ACCOUNTS, ALLOCATIONS
              AND DISTRIBUTIONS

     7.1 Initial Capitalization. Concurrently with the execution of this
Agreement, each Member shall (a) be deemed to have made a Capital
Contribution in the amounts set forth in Schedule 7.1(a) and (b) make a
loan to the Company in the amounts set forth in Schedule 7.1(b).

                                    24

<PAGE>

     7.2 Capital Accounts. A separate Capital Account shall be established
and maintained for each Member in accordance with Treas. Reg. Section
1.704-1(b)(2)(iv).

     7.3 Distributions. Except as set forth in Section 7.4, distributions,
including the amount and timing thereof, shall be determined by the Board
of Managers. Except as provided in Section 9.3(b), all distributions shall
be distributed among the Members in the proportion that the number of
Membership Units held by a Member bears to the total number of Membership
Units held by all of the Members.

     7.4 Tax Distributions. Unless prohibited by applicable law, the Board
of Managers shall cause the Company to distribute, at the end of each
quarterly accounting period of the Company an amount equal to the Tax
Amount for such quarterly accounting period (each a "QUARTERLY
DISTRIBUTION") and, within 60 calendar days after the end of each Fiscal
Year, an amount equal to the excess (if any) of (a) the Tax Amount for such
Fiscal Year over (b) the sum of all Quarterly Distributions previously made
pursuant to this Section 7.4 for such Fiscal Year (each a "FINAL
DISTRIBUTION"). The "TAX AMOUNT" for a Quarterly Distribution means the
product of (x) the Assumed Tax Rate and (y) the estimated taxable income of
the Company for the relevant quarterly accounting period, and for a Final
Distribution means the product of (i) the Assumed Tax Rate and (ii) the
taxable income of the Company for such Fiscal Year. The "ASSUMED TAX RATE"
means, for any period, the marginal tax rate of a corporation subject to
U.S. federal income tax at the highest applicable marginal tax rate in
effect for such period plus 5%. Quarterly Distributions made pursuant to
this Section 7.4 shall be made in a manner consistent with the estimated
annual tax items of the Company, and each Quarterly Distribution shall be
adjusted to the extent Quarterly Distributions for prior quarterly
accounting periods did not correctly estimate such items. If the taxable
income for a Fiscal Year has not been determined within 60 calendar days
after the end of a Fiscal Year the Board of Managers shall make the Final
Distributions called for by this Section 7.4 (if any) on an estimated basis
and in the event that the taxable income exceeds the amount used in the
estimate shall make additional distributions pursuant to this Section 7.4
in respect of such excess when the taxable income for the Fiscal Year is
finally determined.

     7.5 Allocation of Net Profit or Net Loss. Except as provided in
Section 7.6, all items of profit, loss, deduction and credit for each
Fiscal Year (or portion thereof) shall be allocated among the Members (and
credited or debited to their Capital Accounts as provided in Treas. Reg.
ss. 1.704-1(b)(2)(iv)) in the proportion that the number of Membership
Units held by a Member bears to the total number of Membership Units held
by all of the Members.

     7.6 Allocations of Nonrecourse Deductions; Minimum Gain Chargeback;
Special Allocations and Rules. (a) Notwithstanding any other provision of
this Agreement, (i) "partner nonrecourse deductions" (as defined in Treas.
Reg. Section 1.704-2(i)), if any, of the Company shall be allocated to the
Member that bears the economic risk of loss within the meaning of Treas.
Reg. Section 1.704-2(i), and (ii) "nonrecourse deductions" (as defined in
Treas. Reg. Section 1.704-2(b)), if any, of the Company with respect to
each period shall be allocated in the same proportion that the number of
Membership Units held by a Member bears to the total number of Membership
Units held by all of the Members.

                                    25

<PAGE>

          (b) This Agreement shall be deemed to include "qualified income
offset," "minimum gain chargeback" and "partner nonrecourse debt minimum
gain chargeback" provisions within the meaning of Treasury Regulations
under Section 704(b) of the Code. Accordingly, notwithstanding any other
provision of this Agreement, items of gross income shall be allocated to
the Members on a priority basis to the extent and in the manner required by
such provisions.

          (c) Any special allocation of items pursuant to the above
provisions of this Section 7.6 shall be taken into account in computing
subsequent allocations pursuant to Section 7.5 so that the cumulative net
amount of all items allocated to each Member shall, to the extent possible,
be equal to the amount that would have been allocated to such Member if
there had never been any special allocation pursuant to this Section 7.6.

          (d) Losses allocated to any Member with respect to any Fiscal
Year shall not exceed the maximum amount of losses that can be so allocated
without causing or increasing a deficit balance in a Member's Capital
Account as of the end of the partnership taxable year to which such
allocation relates (in excess of deficit amounts the Member is deemed
obligated to restore and for other adjustments as provided in Treas. Reg.
Section 1.704-1(b)(2)(ii)(d)). If some but not all of the Members would
have adjusted Capital Account deficits as a consequence of an allocation of
losses pursuant to the immediately preceding sentence, the limitation set
forth in such sentence shall be applied on a Member-by-Member basis and any
such losses not allocable to a Member as a result of such limitation shall
be allocated to the other Members in accordance with their positive Capital
Account balances so as to allocate the maximum possible losses to each
Member under Treas. Reg. Section 1.704-1(b)(2)(ii)(d).

          (e) For purposes of determining the profits, losses, or any other
items allocable to any period, profits, losses, and any such other items
shall be determined on a daily, monthly, or other basis, as determined by
the Board of Managers under any permissible method under Code Section 706
and the Treasury Regulations thereunder.

          (f) The Capital Accounts of the Members shall be increased or
decreased to reflect a revaluation of Company property at such time as the
Board of Managers shall determine consistent with Treasury Regulation
Section 1.704-1(b).

          (g) The provisions of this Article 7 are intended to comply with
Code Section 704(b) and the Treasury Regulations thereunder and shall be
interpreted consistent therewith.

     7.7 Section 704(c) Allocations. (a) In accordance with Code Section
704(c) and the Treasury Regulations thereunder, income, gain, loss, and
deduction with respect to any property contributed to the capital of 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 such
property to the Company for federal income tax purposes and its initial
gross asset value using any reasonable method determined by the Board of
Managers.

          (b) In the event that the gross asset value of any Company
property is adjusted pursuant to Section 7.6(f) above, subsequent
allocations of income, gain, loss, and deduction

                                    26

<PAGE>

with respect to such property shall take account of any variation between
the adjusted basis of such property for federal income tax purposes and its
gross asset value in the same manner as under Code Section 704(c) and the
Treasury Regulations thereunder.

          (c) Allocations pursuant to this Section 7.7 are solely for
purposes of federal, state, and local taxes and shall not affect, or in any
way be taken into account in computing, any Member's Capital Account or
share of profits, losses, other items, or distributions pursuant to any
provision of this Agreement.

     7.8 No Restoration of Negative Capital Accounts. At no time shall a
Member with a negative balance in its Capital Account have any obligation
to the Company or to any other Member to restore such negative balance.

ARTICLE 8.    INDEMNITIES

     8.1 Indemnities. (a) The Company shall indemnify and hold harmless
(each an "INDEMNIFIED PERSON") (i) each Member and each Manager, (ii) each
Affiliate of each Member, (iii) each of the foregoing's respective
directors, officers, employees and agents and (iv) each of the heirs,
executors, successors and assigns of any of the foregoing, from and against
any and all damages, claims, losses, expenses, costs, obligations and
liabilities including reasonable attorneys' fees and expenses incurred to
enforce the terms of this Section 8.1 (collectively, "LOSSES AND EXPENSES")
suffered or incurred by any such Indemnified Person arising from, relating
to or otherwise in respect of, (A) any liability of the Company or (B) any
act or omission performed or omitted by such Indemnified Person in its
capacity as a Member or Manager (or as an Affiliate, director, officer,
employee, agent, heir, executor, successor or assign of such Member or
Manager or Affiliate) except for acts or omissions constituting gross
negligence, bad faith, fraud or willful misconduct or breach of this
Agreement.

          (b) If a claim by a Third Party is made against an Indemnified
Person hereunder, and if such Indemnified Person intends to seek indemnity
with respect thereto under this Section 8.1, such Indemnified Person shall
promptly notify the Company in writing of such claims setting forth such
claims in reasonable detail, provided that failure of such Indemnified
Person to give prompt notice as provided herein shall not relieve the
Company of any of its obligations hereunder, except to the extent that the
Company is materially prejudiced by such failure. The Company shall have
twenty (20) calendar days after receipt of such notice to undertake,
through counsel of its own choosing, subject to the reasonable approval of
such Indemnified Person, and at its own expense, the settlement or defense
thereof, and the Indemnified Person shall cooperate with it in connection
therewith; provided, however, that the Indemnified Person may participate
in such settlement or defense through counsel chosen by such Indemnified
Person, provided that the fees and expenses of such counsel shall be borne
by such Indemnified Person. If the Company shall assume the defense of a
claim, it shall not settle such claim without the prior written consent of
the Indemnified Person, (i) unless such settlement includes as a term
thereof the giving by the claimant of an unconditional release of the
Indemnified Person from all liability with respect to such claim or (ii) if
such settlement involves the imposition of equitable remedies or the
imposition of any material obligations on such Indemnified Person other
than financial obligations for which such Indemnified Person will be

                                    27

<PAGE>

indemnified hereunder. If the Company shall assume the defense of a claim,
the fees of any separate counsel retained by the Indemnified Person shall
be borne by such Indemnified Person unless and to the extent there exists a
conflict between them as to their respective legal defenses (other than one
that is of a monetary nature), in which case the Indemnified Person shall
be entitled to retain separate counsel, the reasonable fees and expenses of
which shall be reimbursed by the Company. If the Company does not notify
the Indemnified Person within twenty (20) calendar days after the receipt
of the Indemnified Person's notice of a claim of indemnity hereunder that
it elects to undertake the defense thereof, the Indemnified Person shall
have the right to contest, settle or compromise the claim but shall not
thereby be deemed to have waived any right to indemnity therefor pursuant
to this Agreement.

          (c) No Member shall have any obligation or liability to any other
Member arising out of or relating to any liability of the Company.

     8.2 Insurance. The Company may purchase and maintain insurance, on
behalf of the such Persons as the Board of Managers shall determine,
against any liability that may be asserted against, or expense that may be
incurred by, such Persons in connection with the business or activities of
the Company, regardless of whether the Company would have the power to
indemnify such Persons against such liability under the provisions of this
Agreement.

commencement of any such examination or other proceeding and shall keep

determination of Company items at the Company level undertaken by the "tax
matters partner" will be deemed to be Company expenses.

     10.5 Fiscal Year. The Fiscal Year of the Company for financial,
accounting and federal, state and local income tax purposes shall be
determined by the Board of Managers and shall initially be the calendar
year.

     10.6 Tax Elections. The Company intends to be treated as a partnership
