     assigned to it in the Code or the applicable Treasury regulations
     thereunder or in comparable provisions of applicable law.

     2.   Indemnity.

          (a)  Tyco Indemnity.  Tyco hereby indemnifies TyCom and the members of
     the TyCom Group against and hold them harmless from:

               (i) all liability for Income Taxes of any member of the TyCom
          Group attributable to any Pre-Offering Tax Period to the extent in
          excess of Income Taxes previously paid or accrued as an expense with
          respect to such Pre-Offering Tax Period; and

               (ii) all liabilities, costs, expenses (including, without
          limitation, reasonable expenses of investigation and attorneys' fees
          and expenses),

<PAGE>

          losses, damages, assessments, settlements or judgments arising out of
          or incident to the imposition, assessment or assertion of any
          liability or damage described in (i) including those incurred in the
          contest in good faith in appropriate proceedings relating to the
          imposition, assessment or assertion of any such tax, liability or
          damage.

          (b) Tax Benefits. If an indemnification obligation of Tyco under this
     Section 2 arises in respect of an adjustment that makes allowable to a
     member of the TyCom Group any deduction, amortization, exclusion from
     income or other allowance (a "Tax Benefit") which would not, but for such
     adjustment, be allowable, then any payment by Tyco pursuant to this Section
     2 shall be an amount equal to (X) the amount otherwise due but for this
     subsection (b), minus (Y) the present value (determined using an
     appropriate discount rate determined by Tyco) of the product of the Tax
     Benefit multiplied (i) by the maximum federal, foreign or state, as the
     case may be, corporate tax rate in effect at the time such Tax Benefit
     becomes allowable to a member of the TyCom Group or (ii) in the case of a
     credit, by 100 percent.

     3.   Straddle Periods

          In the case of any tax period of a member of the TyCom Group that
     begins before and ends after the Offering Date (a "Straddle Period"),
     Income Taxes for the Pre-Offering Tax Period with respect to such tax
     period shall be computed as if such tax period ended as of the close of
     business on the Offering Date.

     4.   Sole Agreement.

          Any and all existing tax sharing or indemnity agreements or
     arrangements, written or unwritten, between any member of Tyco Group and
     any member of the TyCom Group shall be terminated as of the effective date
     of this Agreement to the extent that such agreement or arrangement relates
     to Income Taxes. As of the date of this Agreement, neither the members of
     the TyCom Group nor the members of Tyco Group shall have any further rights
     or liabilities with respect to Income Taxes thereunder, and this Agreement
     shall be the sole agreement between the members.

     5.   Communication and Cooperation.

          TyCom shall consult and cooperate (and shall cause each member of the
     TyCom Group to cooperate) with Tyco fully at such time and to the extent
     reasonably requested by Tyco in connection with all matters subject to this
     Agreement.

     6.   Audits and Contest.

          (a) Notwithstanding anything in this Agreement to the contrary, Tyco
     shall have full control over all matters relating to any Income Tax return
     or any Income Tax Proceeding relating to (i) any Income Tax matters of the
     Tyco Group,

                                       3
<PAGE>

     and (ii) any Income Tax matters of the TyCom Group relating to a
     Pre-Offering Tax Period. Tyco shall have absolute discretion with respect
     to any decisions to be made, or the nature of any action to be taken, with
     respect to any matter described in the preceding sentence.

          (b) No settlement of any Income Tax Proceeding relating to any matter
     that would cause a payment obligation under Section 2(a) shall be accepted
     or entered into by or on behalf of TyCom or any member of the TyCom Group
     unless Tyco consents thereto in writing (which consent shall not be
     unreasonably withheld).

          (c) TyCom agrees to give prompt notice to Tyco of the assertion of any
     claim, or the commencement of any suit, action or proceeding in respect of
     which indemnity may be sought hereunder.

     7.   Notices.

          Any notice, demand, claim, or other communication under this Agreement
     shall be in writing and shall be deemed to have been given upon the

          This Agreement shall become effective upon the consummation of the
     Offering. All rights and obligations arising hereunder with respect to a
     Pre-Offering Tax Period shall survive until they are fully effectuated or
     performed and, provided, further, that notwithstanding anything in this
     Agreement to the contrary, this Agreement shall remain in effect and its
     provisions shall survive for

<PAGE>

     the full period of all applicable statutes of limitation (giving effect to
     any extension, waiver or mitigation thereof).

     9.   Amendments and Waivers.

          No failure or delay by any party in exercising any right, power or
     privilege hereunder shall operate as a waiver hereof nor shall any single
     or partial exercise thereof preclude any other or further exercise thereof
     or the exercise of any right, power or privilege. This Agreement shall not
     be waived, amended or otherwise modified except by an instrument signed by
     an authorized officer of each of Tyco and TyCom, or in the case of a
     waiver, by the party against whom the waiver is to be effective.

     dispute relating to this Agreement within 20 days, such disagreement or
     dispute shall be resolved by a recognized law firm or accounting firm
     expert in tax matters in the relevant jurisdiction or that is mutually
     acceptable to the parties hereto (a "Referee"). A Referee so chosen shall
     resolve any such disagreement pursuant to such procedures as it may deem
     advisable. Any such resolution shall be binding on the parties hereto
     without further recourse. Except as otherwise provided herein, the costs of
     any Referee shall be apportioned between Tyco and TyCom as determined by
     such Referee in such manner as the Referee deems reasonable, taking into
     account the circumstances of the dispute, the conduct of the parties and
     the result of the dispute.

     12.  Counterparts.

          This Agreement may be executed in any number of counterparts, each of
     which shall be deemed an original, but all of which together shall
