of the Class B Member other than with the consent of the Class A Member; the
Class A Member shall have the option, which must be exercised by the delivery to
the Class B Member of written notice of its intent to exercise its option, and
by the exercise of such option within sixty (60) days after the occurrence of
such Irreconcilable Difference (the "Option Period"), to be assigned all and not
less than all of the Interest of the Class B Member at the Option Price. The
Option Period will automatically be extended for the period necessary to
establish the Option Price.

            (b) In the event of: (A) the Bankruptcy or insolvency of the Class A
Member, SpecTran, or any relevant Affiliate, (B) a Material Breach by the Class
A Member, SpecTran or any relevant Affiliate, or (C) the Class A Member's
failure to exercise, within the Option Period, its option to acquire an
assignment of the Interest of the Class B Member pursuant to Section 10.5(a);
the Class B Member shall have the option to acquire an assignment of all and not

            (c) The term "Option Price" on a given date shall mean the "Fair
Value" of the Company multiplied by the Percentage Interest at issue in the
transaction. For this purpose, the Fair Value of the Company shall be the fair
market value of the Company as a going concern on the day before the

specified below. For purposes of this definition, "Appraiser" shall mean an
investment banking firm, accounting firm, or other firm which is qualified to

as a going concern on the day before the occurrence




                                     -17-



   22



of the Irreconcilable Difference. The Members will then exchange these appraisal
reports. If the Fair Value of the Company in the two reports does not differ by
more than five percent, the Fair Value of the Company shall be the average of
the values of the Company specified in such reports. If the Fair Value of the
Company in the reports differs by more than five percent (5%), the Members
shall jointly select a third Appraiser (familiar with the industry, but with no
connection or business relationship with either of the Members or their
Affiliates) who will review the valuation reports, decide which report more
accurately reflects the Fair Value of the Company, and notify the Company and
the Members of such determination promptly and, in any event, within thirty (30)
days of his appointment, and the value established by such report shall be the
Fair Value of the Company.

process set forth in Section 10.6(b) as required at the election of the Class B
Member by notice given within forty-five (45) days after the Change of Control.

            (b) After a Change of Control of SpecTran, the Class B Member may
require the Acquirer to follow the bid process in this Section 10.6(b) by
providing notice to the Class A Member that the Class B Member will elect to
require the Acquirer to follow the bid process in this Section 10.6(b). Within
fifteen (15) days after the Class A Member's receipt of such notice, the
Acquirer first shall irrevocably offer in writing to acquire an assignment of
all and not less than all of the Interest of the other Member at a price and on
terms determined by the Acquirer. Thereafter, by delivery of written notice
within ten (10) days after its receipt of such initial offer, the other Member
shall either: (i) accept such offer; or (ii) offer to acquire by assignment all
and not less than all of the Interest of the Acquired Member at a price which
is greater than the previous offer under this Section 10.6(b) by the greater of
(A) one million dollars ($1,000,000), or (B) five percent (5%) of the amount of
the previous offer. If the other Member shall have offered to acquire by
assignment all and not less than all of the Interest of the Acquired Member, the
Acquirer shall, within ten (10) days of its receipt of such offer, either: (I)
accept such offer; or (II) offer to acquire by assignment all and not less than
all of the Interest of the other Member at a price which is greater than the
previous offer under this Section 10.6(b) by the greater of (A) one million
dollars ($1,000,000), or (B) five percent (5%) of the amount of the previous
offer. The parties shall continue such process until the highest bid for an
Interest of a Member is made.

            (c) In the event of a Change of Control of General Cable
Corporation, the Class A Member shall have no right to purchase the Class B
Member's interest as a result thereof, but shall retain its rights under Section
10.5(a) to acquire an assignment of all and not



                                     -18-

party to a Related Agreement has committed a Material Breach, it shall serve
notice on the other Member or Affiliate (the "Recipient") describing the
Material Breach. Within ten (10) days, the Recipient will inform the Notifying
Member whether it acknowledges or denies that the Material Breach occurred. If
the Recipient acknowledges that a Material Breach occurred, then, except as
otherwise provided in this Agreement or in a Related Agreement, the parties will
determine within thirty (30) days what the cure will be and how much time will
be necessary, to implement that cure; provided that the parties will, whenever
practicable, implement a cure within such thirty (30) day period. If the
Recipient denies that a Material Breach occurred, then the Members and any
Member's Affiliates that is a party to a Related Agreement at issue will proceed
to arbitration.

          (b) In case of arbitration, it will be held in Wilmington, Delaware in
accord with the rules of the American Arbitration Association, Wilmington,
Delaware ("AAA"). The law applied will be the law of Delaware without reference
to conflicts to laws provisions. There will be one arbitrator appointed either
by the parties or the AAA. The parties acknowledge and agree that the time
period from the giving of the initial notice describing a Material Breach to a
decision on the cure for a Material Breach found by the arbitrator will be no
more than sixty (60) days. Subject to a different allocation of time as may be
agreed by the parties, the parties agree that there will be a twenty-five (25)
day period beginning on the day after the day on which the Material Breach is
denied during which the arbitrator will be appointed and the parties will
conduct discovery. In that period, each party will make available to the other
documents, information and personnel for discovery purposes as requested that
are relevant to the issue. The arbitrator will hear the evidence and make a
determination in the next fifteen (15) days, unless it would work a substantial
injustice to a party. The arbitrator has the power to determine if a Material
Breach has occurred. If the arbitrator determines that a Material Breach did
occur,



                                     - 24 -



   29



then the parties will determine within twenty (20) days what the cure will be
and how much time will be necessary to implement that cure.

            (c) In the event that any claim or dispute is submitted to
arbitration, the non-prevailing party to the arbitration shall pay all expenses
of the arbitration and all reasonable expenses incurred by the prevailing party
in connection with such arbitration, including but not limited to, reasonable
attorneys' fees.

            (d) If a Member acknowledges that it is in Material Breach or if the
arbitrator determines that a Material Breach did occur, but the parties cannot
agree upon the cure and the period to implement such a cure within twenty (20)
days of the acknowledgment of the Material Breach or the decision of the
arbitrator, then the parties shall each submit their proposal for a cure to the
Material Breach to the arbitrator, who will determine which of the two proposals
is most appropriate. The decision of the arbitrator shall be binding upon the
parties and shall be final and nonappealable.
