          (1) if Hanover or any Restricted Subsidiary:

              (a)      has Incurred any Indebtedness since the beginning of such
                       period that remains outstanding on such date of
                       determination or if the transaction giving rise to the

                       EBITDA and Consolidated Fixed Charges for such period
                       will be calculated after giving effect on a pro forma
                       basis to such Indebtedness as if such Indebtedness had
                       been Incurred on the first day of such period (except

                       outstanding on the date of such calculation will be
                       computed based on (i) the average daily balance of such
                       Indebtedness during such four fiscal quarters or such
                       shorter period for which such facility was outstanding or

                       Indebtedness during the period from the date of creation
                       of such facility to the date of such calculation) and the
                       discharge of any other Indebtedness repaid, repurchased,
                       defeased or otherwise discharged with the proceeds of
                       such new Indebtedness as if such discharge had occurred
                       on the first day of such period; or

              (b)      has repaid, repurchased, defeased or otherwise discharged

                       is no longer outstanding on such date of determination or
                       if the transaction giving rise to the need to calculate
                       the Consolidated Coverage Ratio involves a discharge of
                       Indebtedness (in each case other than Indebtedness
                       incurred under any revolving credit facility unless such
                       Indebtedness has been permanently repaid and the related
                       commitment terminated), Consolidated EBITDA and
                       Consolidated Fixed Charges for such period will be
                       calculated after giving effect on a pro forma basis to
                       such discharge of such Indebtedness, including with the
                       proceeds of such new Indebtedness, as if such discharge
                       had occurred on the first day of such period;

          (2) if since the beginning of such period Hanover or any Restricted
              Subsidiary will have made any Asset Disposition or if the
              transaction giving rise to the need to calculate the Consolidated
              Coverage Ratio is an Asset Disposition:

              (a)      the Consolidated EBITDA for such period will be reduced
                       by an amount equal to the Consolidated EBITDA (if
                       positive) directly attributable to the assets which are
                       the subject of such Asset

<PAGE>
                                                                              11

               Disposition for such period or increased by an amount equal to
               the Consolidated EBITDA (if negative) directly attributable
               thereto for such period; and

          (b)  Consolidated Fixed Charges for such period will be reduced by an
               amount equal to the Consolidated Fixed Charges directly
               attributable to any Indebtedness of Hanover or any Restricted
               Subsidiary repaid, repurchased, defeased or otherwise discharged
               with respect to Hanover and its continuing Restricted
               Subsidiaries in connection with such Asset Disposition for such
               period (or, if the Capital Stock of any Restricted Subsidiary is
               sold, the Consolidated Fixed Charges for such period directly
               attributable to the Indebtedness of such Restricted Subsidiary to
               the extent Hanover and its continuing Restricted Subsidiaries are
               no longer liable for such Indebtedness after such sale);

     (3)  if since the beginning of such period Hanover or any Restricted
          Subsidiary (by merger or otherwise) will have made an Investment in
          any Restricted Subsidiary (or any Person which becomes a Restricted
          Subsidiary or is merged with or into Hanover) or an acquisition of
          assets, including any acquisition of assets occurring in connection
          with a transaction causing a calculation to be made hereunder, which
          constitutes all or substantially all of an operating unit, division or
          line of business, Consolidated EBITDA and Consolidated Fixed Charges
          for such period will be calculated after giving pro forma effect
          thereto (including the Incurrence of any Indebtedness) as if such
          Investment or acquisition occurred on the first day of such period;
          and

     (4)  if since the beginning of such period any Person (that subsequently
          became a Restricted Subsidiary or was merged with or into Hanover or
          any Restricted Subsidiary since the beginning of such period) will
          have made any Asset Disposition or any Investment or acquisition of
          assets that would have required an adjustment pursuant to clause (2)
          or (3) above if made by Hanover or a Restricted Subsidiary during such
          period, Consolidated EBITDA and Consolidated Fixed Charges for such
          period will be calculated after giving pro forma effect thereto as if
          such Asset Disposition or Investment or acquisition of assets occurred
          on the first day of such period.

     For purposes of this definition, whenever pro forma effect is to be given
to any calculation under this definition, the pro forma calculations will be
determined in good faith by a responsible financial or accounting officer of
Hanover (including pro forma expense and cost reductions calculated on a basis
consistent with Regulation S-X under the Securities Act). If any Indebtedness
bears a floating rate of interest and is being given pro forma effect, the
interest expense on such Indebtedness will be calculated as if the rate in
effect on the date of determination had been the applicable rate for the entire

<PAGE>
                                                                              12

period (taking into account any Interest Rate Agreement applicable to such
Indebtedness if such Interest Rate Agreement has a remaining term in excess of
12 months).

     "Consolidated EBITDA" for any period means, without duplication, the
      -------------------
Consolidated Net Income for such period, plus the following to the extent
deducted in calculating such Consolidated Net Income:

     (1)  Consolidated Interest Expense;

     (2)  Consolidated Income Taxes;

     (3)  consolidated depreciation expense;

     (4)  consolidated amortization of intangibles;

     (5)  other non-cash charges reducing Consolidated Net Income (excluding any
          such non-cash charge to the extent it represents an accrual of or
          reserve for cash charges in any future period or amortization of a
          prepaid cash expense that was paid in a prior period not included in
          the calculation); and

     (6)  Consolidated Rental Expense.

Notwithstanding the preceding sentence, clauses (2) through (6) relating to
amounts of a Restricted Subsidiary of a Person will be added to Consolidated Net
Income to compute Consolidated EBITDA of such Person only to the extent (and in
the same proportion) that the net income (loss) of such Restricted Subsidiary
was included in calculating the Consolidated Net Income of such Person and, to
the extent the amounts set forth in clause (1) and clauses (3) through (6) are
in excess of those necessary to offset a net loss of such Restricted Subsidiary
or if such Restricted Subsidiary has net income for such period included in
Consolidated Net Income, only if a corresponding amount would be permitted at
the date of determination to be paid as a dividend to Hanover by such Restricted
Subsidiary without prior approval (that has not been obtained), pursuant to the
terms of its charter and all agreements, instruments, judgments, decrees,
orders, statutes, rules and governmental regulations applicable to that
Restricted Subsidiary or its stockholders.

period, the sum, without duplication, of Consolidated Interest Expense and

period, taxes imposed upon such Person or other payments required to be made by

and its Restricted Subsidiaries (to the extent such income or profits were
included in computing Consolidated Net Income

<PAGE>
                                                                              13

be remitted to any governmental authority.

          Indebtedness in respect of the relevant lease giving rise thereto to
          the extent not already included in Consolidated Rental Expense,
          determined as if such lease were a capitalized lease in accordance
          with GAAP and the interest component of any deferred payment
          obligations;

     (2)  amortization of debt discount and debt issuance cost;

     (3)  non-cash interest expense;

     (4)  commissions, discounts and other fees and charges owed with respect to

          Subsidiaries that was capitalized during such period;

     (8)  the product of (a) all dividends paid or payable in cash, Cash
          Equivalents or Indebtedness or accrued during such period on any
          series of Disqualified Stock of such Person or on Preferred Stock of
          its Restricted Subsidiaries payable to a party other than Hanover or a
          Wholly-Owned Subsidiary, times (b) a fraction, the numerator of which
          is one and the denominator of which is one minus the then current
          combined federal, state, provincial and local statutory tax rate of
          such Person, expressed as a decimal, in each case, on a consolidated
          basis and in accordance with GAAP; and

     (9)  the cash contributions to any employee stock ownership plan or similar
          trust to the extent such contributions are used by such plan or trust

          however, that there will be excluded therefrom any such interest
          expense of any Unrestricted Subsidiary to the extent the related
          Indebtedness is not Guaranteed or paid by Hanover or any Restricted
          Subsidiary.

Subsidiaries with respect to Interest Rate Agreements.

     "Consolidated Net Income" means, for any period, the net income (loss) of

          Subsidiary, except that:

          (a)  subject to the limitations contained in clauses (4), (5) and (6)
               below, Hanover's equity in the net income of any such Person for
