Mr. Robert L. Doretti
297 Commonwealth Avenue, No. 5
Boston, MA  02115

Dear Bob:

         On behalf of ON Technology Corporation (the "Company"), I am pleased to
offer you the position of President and Chief Executive Officer of the Company.
The terms of your employment relationship with the Company are as set forth
below, as approved by the Company's Board of Directors.

1.  POSITION. You will serve in a full-time capacity as President and Chief
Executive Officer of the Company, reporting to the Company's Board of Directors
and based in the Company's Waltham, Massachusetts office. As such, you will have
such responsibilities as are commensurate with your position and determined by
the Board. You will also be appointed a member of the Board at the first meeting
of the Board that follows the commencement of your employment with the Company.

2.  BASE SALARY, BENEFITS. You will be paid a base salary as determined by the
Board of Directors on an annual basis, at a rate of not less than $250,000. Your
salary will be payable in accordance with the Company's standard payroll
policies (subject to normal required withholding). You will receive a vacation
package comparable to that provided for key executives and will be eligible to
participate in the Company's life, disability, medical, dental and other
insurance programs available to key executives ("Benefits"). In addition, the
Compensation Committee of the Company's Board of Directors ("Compensation
Committee") will use good faith efforts to obtain post-employment health
insurance for you and your spouse upon your termination of employment at
retirement age in accordance with Company policy or upon your death or
disability, so long as the aggregate cost of such health insurance to the
Company, after any employee contribution, is not significant and does not
require any payment of premiums for more than two years after the date of this
letter. Alternatively, the Company and you may agree upon other arrangements
having a comparable purpose and cost. Any such post-retirement health insurance
is included in "Benefits".

3.  SIGN-ON BONUS. Effective with the commencement of your employment with the
Company, you will receive a stock option having the following terms:

         Option Shares:             0.25% of the outstanding common stock of the
                                    Company (36,732 shares).

         Exercise Price:            Market price on date of grant.
<PAGE>

         Vesting:                   Vested immediately in full.

         Stock                      Restriction: Stock purchased pursuant to
                                    this option before the first anniversary of
                                    the grant will be subject to a repurchase
                                    option in favor of the Company at the
                                    Exercise Price if your employment with the
                                    Company is terminated by you without
                                    Constructive Termination (as defined below),
                                    or by the Company for Cause (as defined
                                    below), prior to the first anniversary of
                                    the grant.

4.  INCENTIVE PROGRAM. The Company has an incentive compensation program for key
executives ("Incentive Program") tied to performance against the quarterly and
annual plan ("Plan"). The Plan is adopted for each fiscal year by the
Compensation Committee, based upon recommendations by management. As Chief
Executive, you will have a critical input in establishing the Plan on an annual
basis; we expect that the Plan for calendar year 2000 will be developed under
your supervision during the 45-day period after your commencement of employment
and will be approved by the Compensation Committee promptly thereafter. Under
the Incentive Program, you will be eligible for an annual bonus equal to
$150,000 if the Company's performance meets the Plan objectives. The Incentive
Program will provide that you will receive a maximum bonus of 150% of your
annual base salary if the Company's performance reaches the requisite parameters
specified in the Plan.

5.  STOCK OPTION PERFORMANCE BONUS. You will receive a performance bonus in the
form of a stock option (the "Performance Stock Option") with the following
terms:

         Option Shares:             2.5% of the outstanding common stock of the
                                    Company (367,325 shares)

         Exercise Price:            Market price on date of grant.

         Vesting:                   Vested in full upon the seventh anniversary
                                    of the grant.

         Acceleration:              Vesting will be accelerated during the first
                                    and second fiscal years as follows: (a) for
                                    each of the eight fiscal quarters in
                                    calendar year 2000 and 2001, between 8% and
                                    10% of the Option Shares will be accelerated
                                    in a linear progression, corresponding with
                                    the Company achieving between 80% and 100%
                                    of the applicable fiscal quarter benchmark
                                    set forth in the Plan; and (b) for the
                                    entire fiscal years 2000 and 2001, options
                                    for between 8% and 10% of the Option Shares
                                    will be accelerated in a linear progression,
                                    corresponding with the Company achieving
                                    between 80% and 100% of the applicable
                                    fiscal year benchmark set forth in the Plan.
                                    For example, if the Company achieves 60% of
                                    the Plan in Q1, 85% in Q2, 100% in Q3, 110%
                                    in Q4, and 90% for the fiscal year, then the
                                    option would be accelerated 0%, 8.5%, 10%,
                                    10% and 9%, respectively, or a total of
                                    137,746 Option Shares for such fiscal year.
                                    If the Company exceeds Plan for one or more
                                    quarters or for a fiscal year, but the
                                    maximum percentage of Option Share
                                    acceleration (50%) has not been achieved for
                                    such fiscal year (due to below-Plan
                                    performance for other quarters or the fiscal
                                    year), then the Compensation Committee will
                                    include in its Incentive Program, in
                                    additional to the cash amounts referenced in
                                    Section 4,

                                       2
<PAGE>

                                    some or all of the Option Shares that would
                                    have accelerated had the Plan for the
                                    applicable quarters or fiscal year been met.

6.  STOCK OPTION. You will be granted a stock option ("Time Vesting Option")
with the following terms:

         Option Shares:             3% of the outstanding common stock of the
                                    Company (440,790 shares).

         Exercise Price:            Market price on date of grant.

         Vesting:                   The nonqualified portion of the Option will
                                    be fully exercisable upon grant, subject to
                                    the Company's right to repurchase the shares
                                    issuable upon exercise of the option upon
                                    termination of your employment by the
                                    Company, which right lapses over four years
                                    as follows: 25% lapses upon the first
                                    anniversary of the grant and 75% lapses over
                                    the three years thereafter in equal
                                    quarterly increments. The incentive stock
                                    option portion of the Option will be a
                                    standard option subject to four year vesting
                                    in accordance with the schedule set forth in
                                    the previous sentence.

7.  NATURE OF STOCK OPTIONS. The Stock Options referenced in paragraphs 3, 5 and
6 above will be incentive stock options to the extent permitted by applicable
tax regulations. Options in excess of the incentive stock option limits will be
non-qualified stock options.

8.  OTHER INCENTIVE COMPENSATION. During your employment by the Company, you
will be eligible for additional awards under the Company's 1992 Employee and
Consultant Stock Option Plan, under any subsequent similar plans or under other
incentive programs or plans adopted from time to time by the Board of Directors,
as determined by the Compensation Committee or the Board of Directors.

9.  TERMINATION OF EMPLOYMENT. If your employment with the Company is terminated
by your death or disability or by the Company for any reason other than for
Cause, or in the case of Constructive Termination, you (or your estate) will be
entitled to receive (a) $250,000, paid as though you were still employed by the
Company over a period of 12 months in installments in accordance with the
Company's normal practices, (b) continued Benefits during the 12 months
following such termination, (c) 12 months of acceleration of vesting (or
comparable reduction in the Company's right to repurchase your shares with
respect to the nonqualified Time Vesting Option) and, if the termination of
employment occurs before the end of the second fiscal year after grant of the
Performance Stock Option, then the Company shall be deemed to have met 100% of
Plan for any remaining quarters and fiscal year in the 12 month period
commencing on such termination, including the quarter then in progress, but
excluding any quarter ending after such 12 month period, (d) an opportunity to
exercise your stock options during the period of 12 months (three months for
incentive stock options) following such termination to the extent vested in

cash bonus earned but not yet paid for completed quarters and fiscal years under
the Plan as well as a prorated amount of the quarterly and annual cash bonus
pursuant to the Plan for the quarter and fiscal year during which termination of
your employment occurs, based on the number of days of the quarter or fiscal
year, as applicable, that you were employed by the Company. The Company will
obtain and maintain life insurance for the benefit

of your estate to cover the exercise price of vested and unexercised stock
options held by you in the event of your death.

         You will not be entitled to any additional payments, salary, bonus or
benefits in the event of termination for Cause. For the purposes of this
Agreement, "Cause" means a determination by a majority of the Board in its
reasonable judgment (after providing written notice to you specifying in
reasonable detail the specific conduct that it considers to constitute cause and
stating the date, time and place for a special board meeting to consider the
same and after providing you and your counsel the opportunity to be heard at
such board meeting) that you have (a) engaged in acts in violation of the law,
(b) breached your fiduciary duty to the Company or duties of loyalty or care to
the Company, (c) willfully disobeyed the good faith, lawful policies or
instructions of the Board, or (d) violated the provisions of Paragraph 9 of this
Agreement. For the purposes of this Agreement, "Constructive Termination" means
a material diminution of duties, change in title or reporting relationship,
change in location or reduction in base salary or Benefits.

10. CHANGE OF CONTROL. The stock options described in this Agreement will
provide for 24 months acceleration of vesting (or comparable reduction in the
Company's right to repurchase your shares with respect to the nonqualified Time
Vesting Option) upon a Change of Control (as defined below) of the Company. In
addition, if the Change of Control occurs before the end of the second fiscal
year after grant of the Performance Stock Option, then the Company shall be
deemed to have met 100% of Plan for any remaining quarters and fiscal year in
the fiscal year during which such Change of Control occurs. For a period of 12
months following a Change of Control of the Company, if your employment is
terminated by the Company for any reason other than for Cause or is terminated
by Constructive Termination, you will be entitled to receive the severance
benefits set forth in Paragraph 8 above. For the purposes of this Agreement,
"Change of Control" means any sale of all or substantially all of the Company's
assets or any merger, consolidation or stock sales which results in the holders
of the Company's capital stock immediately prior to such transaction owning less
than 50% of the voting power of the Company's capital stock immediately after
such transaction.

11. STANDARD EMPLOYEE AGREEMENTS. Like all Company employees, you will be
expected to sign and comply with an Employee Confidentiality Agreement (the
"Employee NDA") which requires, among other provisions, the assignment of patent
and other intellectual property rights to any invention or other trade secrets
created during your employment with the Company and non-disclosure of
proprietary information. Your employment will be contingent upon and not be
deemed effective until you have executed and returned the Employee NDA to the
Company. In addition, you will abide by the Company's strict policy that
prohibits any new employee from using or bringing with him or her from any
previous employer any confidential information, trade secrets, or proprietary
materials or processes of such former employer. You also agree that, during the
term of your employment with the Company and for one year thereafter, you will
not actively engage in any other employment, occupation, consulting or other
business that directly or indirectly competes with the business in which the
Company is now involved or becomes involved during the term of your employment;
will not divert existing or prospective customers of the Company; will not
solicit or hire any Company employees; and will not engage in any other
activities that conflict with your obligations to the Company. You will also be
expected to sign stock option agreements in form and substance satisfactory to
the Company for the stock options described in this Agreement.

12. BUSINESS EXPENSES. You will be entitled to reimbursement by the Company for
all reasonable business expenses that you incur or pay in the performance of
your duties and responsibilities hereunder (including but not limited to travel
and automobile), subject to such reasonable substantiation and documentation as
may be specified by the Company from time to time.

13. AT -WILL EMPLOYMENT. You will be an employee-at-will, meaning that either
you or the Company may terminate your employment relationship at any time,
without notice, for any reason or no reason, subject to the Company's
obligations set forth in this offer letter.

mutually determined but no later than full-time on Tuesday, February 1, 2000.

15. EXPIRATION. This offer expires January 31, 2000.

16. FEDERAL IMMIGRATION LAW. For purpose of federal immigration law, you will be
required to provide the Company documentary evidence of your identity and
eligibility for employment in the United States. Such documentation must be
provided to us within 3 business days of your commencement date, or our
employment relationship with you may be terminated.

17. ENTIRE AGREEMENT. This Agreement, together with your stock option
agreements, and your Employee NDA, constitutes the entire agreement between the
parties and supersedes all other agreements or understandings.

         Bob, on behalf of the Board, let me indicate how pleased I am to extend
this offer, and how much I look forward to working with you. Please indicate
your acceptance by signing and returning the enclosed copy of this letter.

basis points per annum and the 10-year Tranche of the Loan shall
bear interest on the unpaid principal amount thereof from the date

2 basis points per annum.

     B. Special Interest.  The Lender and the Company have entered into
a Registration Rights Agreement (the "Registration Rights Agreement")
dated March 26, 1999 with Donaldson, Lufkin & Jenrette Securities

each series for debt securities of that series with identical terms
(except for transfer restrictions); (B) use their best efforts to
cause the registration statement to become effective within 150 days
after the closing date of the offering of the Secured Notes; and
(C) complete the registered exchange offer within 180 days after the
closing date of the offering of the Secured Notes.  Under certain
circumstances, the Lender and the Company may be required to file a
shelf registration statement for the Secured Notes registering the
resale of the Secured Notes.  If the Lender and the Company do not
comply with their obligations under the Registration Rights Agreement,
the Lender will be required to pay additional interest ("Special
Interest") specified in Section 5 of the Registration Rights
Agreement.  The Company will pay on each date that the Lender pays
Special Interest to the Holders of the Secured Notes as Special
Interest on the Loan an amount equal to the percentage of Special
Interest, if any, which the Lender owes to the Holders of the Secured
Notes that the principal amount of the Loan bears to the total
aggregate principal amount of the Loan and all Other Loans then
outstanding.  Such payment shall be paid directly to the Trustee for
deposit into the Issuer Escrow Account.

          Notwithstanding any provisions of this Section 2.2 or any
other provision herein, in no event will the combined sum of
interest (cash or otherwise) on the Loan exceed the maximum amount
permitted by applicable law.

     C. Interest Payments.  Interest (including Special Interest, if any,
and Additional Amounts, if any) shall be payable semi-annually on

a.m. (New York time) on the date of payment and shall be paid directly
to the Trustee for deposit into the Issuer Escrow Account.

     D. Post-Maturity Interest.  Any principal payments on the Loan not paid
when due and, to the extent permitted by applicable law, any interest
payment on the Loan not paid when due, in each case whether at Stated
Maturity, by notice of prepayment, by acceleration or otherwise, shall
thereafter bear interest payable upon demand at a rate of interest
otherwise payable under this Agreement for the Loan but in no event to
exceed the maximum interest rate permitted by applicable law.

     E. Computation of Interest.  Interest on the Loan shall be computed on
the basis of a 360-day year of twelve 30-day months.

     2.3 Redemptions.

     A. Redemption upon Loss of the Mortgaged Rig.  If an Event of Loss
occurs at any time with respect to the Mortgaged Rig attributable to
the Loan, the Company shall apply funds in an amount (the "Loss
Redemption Amount") equal to the principal amount of the Loan
outstanding on the date (the "Loss Date") on which such Event of Loss
was deemed to have occurred, together with all accrued and unpaid
interest (including Special Interest, if any, and Additional Amounts,
if any) thereon, to the prepayment of the Loan.  If an Event of Loss
occurs at any time with respect to any Other Mortgaged Rig, the
Indenture and the applicable Other Loan Agreement require that the
Company shall apply funds to the principal amount of the applicable
Other Loan secured by the Other Mortgaged Rig outstanding on the Loss
Date for such other Mortgaged Rig, together with all accrued and
unpaid interest (including Special Interest, if any, and Additional
Amounts, if any) thereon, to the payment of such Other Loan.  If a
Default under the Indenture shall have occurred and be continuing at
the time of the receipt of the Event of Loss Proceeds with respect to
such Other Mortgaged Rig, the Indenture requires, and the Company
hereby agrees, that it shall prepay the Loan and the remaining Other
Loans on a pro rata basis in an aggregate amount equal to the excess
of the Net Event of Loss Proceeds over the Loss Redemption Amount, if
any, together with all accrued and unpaid interest (including Special
Interest, if any, and Additional Amounts, if any) thereon for the
Other Loan which is secured by such Other Mortgaged Rig.  All payments
on the Loan shall be allocated on a pro rata basis between the
Tranches and shall be made directly to the Trustee for deposit into
the Issuer Escrow Account.

     B. Redemption upon Sale of the Mortgaged Rig.  If the Mortgaged Rig
or the Capital Stock of a Subsidiary Guarantor then owning the Mortgaged
Rig is sold in compliance with the terms of the Indenture, the Company
shall apply funds in an amount (the "Sale Redemption Amount") equal to
the principal amount of the Loan secured by the Mortgaged Rig on the
date of such sale (the "Sale Date"), together with all accrued and
unpaid interest (including Special Interest, if any, and Additional
Amounts, if any thereon, plus any additional amounts required by the

petition or answer or consent seeking reorganization or relief under
U.S. bankruptcy laws, as now or hereafter constituted, or any other
applicable Federal, state or foreign bankruptcy, insolvency or other
similar law; or (iv) the consent by the Company or any Significant
Subsidiary to the filing of such petition or to the appointment of or
taking possession by a custodian, receiver, liquidator, assignee,
trustee, sequestrator or similar official of the Company or any
Significant Subsidiary or of any substantial part of the property or
assets of the Company or any Significant Subsidiary, or the making by
the Company or any Significant Subsidiary of an assignment for the
benefit of creditors; or (v) the admission by the Company or any
Significant Subsidiary in writing of its inability to pay its debts
generally as they become due; or (vi) the taking of corporate action
by the Company or any Significant Subsidiary in furtherance of such
action;

     THEN (i) upon the occurrence of any Event of Default described
in the foregoing Section 6.7 or 6.8, all of the unpaid principal
amount of and accrued interest on the Loan and all other
outstanding Obligations shall automatically become immediately due
and payable, without presentment, demand, protest, waiver of notice
of intent to accelerate and waiver of notice of such acceleration
or notice of any other kind or other requirements of any kind, all
of which are hereby expressly waived by the Company, and
Obligations and the Loan Commitment of the Lender hereunder shall
thereupon terminate, and (ii) upon the occurrence of any other
Event of Default, the Lender shall, upon written notice of the
Lender, to the Company, upon written notice of the Trustee or the
Collateral Agent to the Company and the Lender, or upon written
notice of a Holder or Holders of the Secured Note or Notes, to the
Company, the Lender, the Collateral Agent and the Trustee, declare
all of the unpaid principal amount of and accrued interest on the
Loan and all other outstanding Obligations to be, and the same
shall forthwith become, due and payable, and the obligations and
Loan Commitments of the Lender hereunder shall thereupon terminate;
provided, however, that upon the occurrence of an Event of Default
described in Section 6.4 of this Agreement or an "event of default"
under Section 6.4 of any Other Loan Agreement, the Lender shall not
declare the Obligations hereunder to be due and payable for a
period of 60 days after notice of the occurrence of such Event of
Default or "event of default."  Nevertheless, if at any time after
acceleration of the Maturity of the Loan, the Company shall pay all
arrears of interest and all payments on account of the principal
thereof which shall have become due otherwise than by acceleration
(with interest on principal and, to the extent permitted by law, on
overdue interest, at the rates specified in this Agreement or the
Notes) and all Events of Default and Potential Events of Default
(other than non-payment of principal of and accrued interest on the
Loan and the Notes due and payable solely by virtue of
acceleration) shall be remedied or waived pursuant to Section 7.6,
then the Lender shall, upon receipt of the written notice from the
Collateral Agent and the Trustee of such remedy or waiver, by
written notice to the Company rescind and annul the acceleration
and its consequences; but such action shall not affect any
subsequent Default, Event of Default or Potential Event of Default
or impair any right consequent thereon.

SECTION 7 MISCELLANEOUS

     7.1 Pledges and Assignments of Loan and Note.  The Lender shall have
the right at any time to sell, pledge, assign, transfer or negotiate
all or any portion of the Note or its Loan Commitment.  The Company
acknowledges that the Lender will pledge its rights under this
Agreement, the Notes, the Mortgage and the Other Loan Documents to the
Collateral Agent pursuant to the Issuer Security Agreement to secure
the Lender's obligations under the Indenture and the Secured Notes.

     7.2 Expenses.  Whether or not the transactions contemplated hereby
shall be consummated, the Company, its successors and assigns agrees
to promptly pay (i) all the actual costs and expenses of preparation
of the Loan Documents and all the costs of furnishing all opinions by
counsel for the Company (including without limitation any opinions
requested by the Lender as to any legal matters arising hereunder),
and of the Company's performance of and compliance with all agreements
and conditions contained herein on its part to be performed or
complied with; (ii) the reasonable fees, expenses and disbursements of
counsel to the Lender and the Trustee and the Collateral Agent, their
successors and assigns (including allocated costs of internal counsel)
in connection with the negotiation, preparation, execution and
administration of the Loan Documents and the Loan hereunder, and any
amendments, modifications and waivers hereto or thereto and consents
to departures from the terms hereof and thereof; and (iii) after the
occurrence of an Event of Default, all costs and expenses (including
reasonable attorneys fees, including allocated costs of internal
counsel, and costs of settlement) incurred by the Lender, its
successors and assigns in enforcing any Obligations of or in
collecting any payments due from the Company hereunder or under the
Notes by reason of such Event of Default or in connection with any
refinancing or restructuring of the credit arrangements provided under
this Agreement in the nature of a "work-out" or of any insolvency or
bankruptcy proceedings.

     7.3 Indemnity.  In addition to the payment of expenses pursuant to
Section 7.2, whether or not the transactions contemplated hereby shall
be consummated, the Company agrees to indemnify, pay and hold the
Lender, the Collateral Agent, the Trustee and any Holder of the
Secured Notes and holder of the Notes, and each of their officers,
directors, employees, and agents, (collectively called the
"Indemnitees"), harmless from and against any all other liabilities,
obligations, losses, damages, penalties, actions, judgments, suits,
claims, costs, expenses and disbursements of any kind or nature
whatsoever (including, without limitation, the fees and disbursements
of counsel for such Indemnitees in connection with any investigative,
administrative or judicial proceeding commenced or threatened, whether
or not such Indemnitee shall be designated as a party thereto), which
may be suffered by imposed on, incurred by, or asserted against that
Indemnitee, in any manner resulting from, connected with, in respect
of, relating to or arising out of this Agreement, the Notes, the
Mortgage, the Lender's agreement to make the Loan or the use or
intended use of any of the proceeds of the Loan hereunder or the
Transactions (the "indemnified liabilities"); provided, however, that
the Company shall have no obligation to an Indemnitee hereunder with
respect to indemnified liabilities (i) to the extent such is finally
judicially determined to have resulted solely from (A) the gross
negligence or willful misconduct of that Indemnitee or (B) the failure
of such Indemnitee to perform its obligations under any Loan Document
or (C) such Indemnitee's violation of law or (ii) in connection with
the obligations of any Indemnitee under any Loan Document.  To the
extend that the undertaking to indemnify, pay and hold harmless set
forth in the preceding sentence may be unenforceable because it is
violative of any law or public policy, the Company shall contribute
the maximum portion which it is permitted to pay and satisfy under
applicable law to the payment and satisfaction of all indemnified
liabilities incurred by the Indemnitees or any of them.

     7.4 Additional Amounts. Except to the extent required by any applicable
law, regulation law, regulation or governmental policy, any and all
payments of, or in respect of the Loan, this Agreement, the Notes, any
Loan Document or any Secured Note shall be made free and clear of  and
without deduction for or on account of any and all present or future
taxes, levies, imposts, deduction, charges or withholdings and all
liabilities with respect thereto imposed by Panama, The Bahamas, The
Marshall Islands or any other jurisdiction with which the Company or
any Subsidiary has some connection (including any jurisdiction (other
than the United States of America) from or through which payments
under this Agreement, the Notes, any Loan Document, the Guarantee or
the Secured Notes are made) or any political subdivision of or any
taxing authority in any such jurisdiction ("Panamanian Taxes,"
"Bahamian Taxes," "MI Taxes," or "Other Taxes," respectively).  If the
Lender, the Company or any Subsidiary Guarantor shall be required by
law to withhold or deduct any Panamanian Taxes, Bahamian Taxes, MI
Taxes, or Other Taxes from or in respect of any sum payable under this
Agreement, the Notes, any Loan Document, the Guarantee or the Secured
Notes, the sum payable by the Company or such Subsidiary Guarantor, as
the case may be, thereunder shall be increased by the amount
("Additional Amounts") necessary so that after making all required
withholdings and deductions, Lender or any Holder or beneficial owner
of Secured Notes shall receive an amount equal to the sum that it
would have received had not such withholdings and deductions been
made; provided that any such sum shall not be paid in respect of any
Panamanian Taxes, Bahamian Taxes, MI Taxes or Other Taxes to a Holder
(an "Excluded Holder") (i) resulting from the beneficial owner of such
Secured Note carrying on business or being deemed to carry on business
in or through a permanent establishment or fixed base in the relevant
taxing jurisdiction or having any other connection with the relevant
taxing jurisdiction or any political subdivision thereof or any taxing
authority therein other than the mere holding or owning of such
Secured Note, being a beneficiary of the Guarantee or any applicable
Subsidiary Guarantee, the receipt of any income or payments in respect
of such Secured Note, the Loan, the Guarantee or any applicable
Subsidiary Guarantee or the enforcement of such Secured Note, the
Loan, the Guarantee or any applicable Subsidiary Guarantee, or (ii)
that would not have been imposed but for the presentation (where
presentation is required) of such Secured Note for payment more than
180 days after the date such payment became due and payable or was
duly provided for, whichever occurs later.  The Lender, the Company or
the Subsidiary Guarantors, as applicable, will also (i) make such
withholding or deduction and (ii) remit the full amount deducted or
withheld to the relevant authority in accordance with applicable law,
and, in any such case, the Lender is required to furnish under the
Indenture to each Holder on whose behalf an amount was so remitted,
within 30 calendar days after the date the payment of any Panamanian
Taxes, Bahamian Taxes, MI Taxes or Other Taxes is due pursuant to
applicable law, certified copies of tax receipts evidencing such
payment by the Lender, the Company or the Subsidiary Guarantors, as
applicable.  The Company will, upon written request of each Holder
(other than an Excluded Holder), reimburse each such holder for the
amount of (i) any Panamanian Taxes, Bahamian Taxes, MI Taxes or Other
Taxes so levied or imposed and paid by such Holder as a result of
payments made under or with respect to any Secured Notes, and (ii) any
Panamanian Taxes, Bahamian Taxes, MI Taxes or Other Taxes so levied or
imposed with respect to any reimbursement under the foregoing clause
(i) so that the net amount received by such Holder (net of payments
made under or with respect to such Secured Notes, the Loan, the
Guarantee or the applicable Subsidiary Guarantees) after such
reimbursement will not be less than the net amount the Holder would
have received if Panamanian Taxes, Bahamian Taxes, MI Taxes or Other
Taxes on such reimbursement had not been imposed.

     At least 30 calendar days prior to each date on which any
payment under or with respect to the Secured Notes is due and
payable, if the Lender, the Company or the Subsidiary Guarantors,
as applicable, will be obligated to pay Additional Amounts with
respect to such payment, the Lender, the Company or the Subsidiary
Guarantors, as applicable, will deliver to the Trustee an officer's
certificate stating the fact that such Additional Amounts will be
payable and the amounts will be payable and the amounts so payable
and will set forth such other information necessary to enable the
Trustee to pay such Additional Amounts to Holders on the payment
date.

     7.5 Taxes and Other Taxes.

     A. Any and all payments by the Company hereunder or under any of the
other Loan Documents shall be made free and clear of and without
deduction or withholding for any and all present or future Taxes,
unless such Taxes are required by law or the administration thereof to
be deducted or withheld and excluding (a) in the case of each Lender,
Taxes imposed on its net income and franchise taxes or taxes on gross
receipts and capital imposed on it by the jurisdiction under the laws
of the United States or any political subdivision thereof (all such
nonexcluded Taxes being hereinafter referred to as "Covered Taxes").
If the Company shall be required by Law or the administration thereof
to deduct or withhold any Covered Taxes from or in respect of any sum
payable hereunder or under any other Loan Documents, the sum payable
shall be increased as may be necessary so that after making all
required deductions or withholdings (including deductions or
withholdings applicable to additional amounts paid under this
paragraph), the Lender receives an amount equal to the sum it would
have received if no such deduction or withholding had been made;
(b) the Company shall make such deductions or withholdings; and
(c) the Company forthwith shall pay the full amount deducted or
withheld to the relevant taxation or other authority in accordance
with applicable Law.

     B. The Company agrees to pay forthwith any present or future stamp
documentary taxes or any other excise or property taxes charges or
similar levies (all such taxes, charges and levies being herein
referred to as "Other Taxes") imposed by any jurisdiction (or any
political subdivision or taxing authority thereof or therein) which
arise from any payment made by the Company hereunder or under any of
the other Loan Documents or from the execution, delivery or
registration of, or otherwise with respect to, this Agreement or any
of the other Loan Documents.

     C. The Company agrees to indemnify the Lender for the full amount of
Covered Taxes or Other Taxes not deducted or withheld and paid by the
Company in accordance with Section 7.5(A) and (B) to the relevant
taxation or other authority and any Taxes other than Covered Taxes or
Other Taxes imposed by any jurisdiction on amounts payable by the
Company under this Section 7.5 paid by the Lender and any liability
(including penalties, interest and expenses) arising therefrom or with
respect thereto, whether or not any such Taxes or Other Taxes were
correctly or legally asserted.  Payment under this indemnification
shall be made within 30 days from the date the Lender makes written
demand therefor.  A certificate as to the amount of such Taxes or
Other Taxes and evidence of payment thereof submitted to the Company
shall be prima facie evidence, absent manifest error, of the amount
due from the Company to the Lender.

     D. The Company shall furnish to the Lender the original or a certified
copy of a receipt evidencing any payment of Taxes or Other Taxes made
by the Company as soon as such receipt becomes available.

     E. The provisions of this Section 7.5 shall survive the termination
of the Agreement and repayment of all Obligations.

     7.6 Amendments and Waivers.  No amendment, modification, termination
or waiver of any term or provision of this Agreement, of the Note, the
Mortgage or any Other Loan Document or consent to any departure by the
Company therefrom, shall in any event be effective without the prior
written concurrence of the Company, the Lender, the Collateral Agent
and the Trustee, and, upon the request of the Lender, the Collateral
Agent or the Trustee, the receipt of a written opinion of counsel of
the Company addressed to the Lender, the Collateral Agent and the
Trustee to the effect that such amendment, modification, termination,
waiver or consent does not violate or conflict with any of the terms
and provisions of the Indenture or any Contractual Obligations of the
Company.

     7.7 Independence of Covenants.  All covenants hereunder shall be
given independent effect so that if a particular action or condition is
not permitted by any of such covenants, the fact that it would be
permitted by an exception to, or be otherwise within the limitation
of, another covenant shall not avoid the occurrence of an Event of
Default or Potential Event of Default if such action is taken or
condition exists.

     7.8 Notices.  Unless otherwise provided herein, any notice or other
communications herein required or permitted to be given shall be in
writing and may be personally served, telecopied or sent by mail and
shall be deemed to have been given when delivered in person, upon
receipt of telecopy against receipt of answer back or four Business
Days after depositing it in the mail, registered or certified, with
postage prepaid and properly addressed; provided, however, that
notices shall not be effective until received.  For the purposes
hereof, the addresses of the parties hereto (unless notice of a change
thereof is delivered as provided in this Section 7.8) shall be set
forth under each party's name on the signature pages hereto.

     7.9 Survival of Warranties and Certain Agreements.  All agreements,
representations and warranties made herein and in the other Loan
Documents shall survive the execution and delivery of this Agreement
and in the other Loan Documents, the making of the Loan hereunder and
the execution and delivery of the Notes or the Loan Documents and,
notwithstanding the making of the Loan, the execution and delivery of
the Notes and the other Loan Documents or any investigation made by or
on behalf of any party, shall continue in full force and effect.  The
closing of the transactions herein contemplated shall not prejudice
any right of one party against any other party in respect of anything
done or omitted hereunder or in respect of any right to damages or
other remedies.

     7.10 Failure or Indulgence Not Waiver; Remedies Cumulative.  No
failure or delay on the part of the Lender or the holder of the Notes
or the Trustee in the exercise of any power, right or privilege or be
construed to be a waiver of any default or acquiescence therein, nor
shall any single or partial exercise of any such power, right or
privilege preclude other or further exercise thereof or of any other
right, power or privilege.  All rights and remedies existing under
this Agreement, the Notes or any other Loan Document are cumulative to
and not exclusive of any rights or remedies otherwise available.

     7.11 Severability.  In case any provision in or obligation under this
Agreement, under a Guarantee or the Notes shall be invalid, illegal or
unenforceable in any jurisdiction, the validity, legality and
enforceability of the remaining provisions or obligations, or of such
provision or obligation in any other jurisdiction, shall not in any
way be affected or impaired thereby.

     7.12 Headings.  Section and Section headings in this Agreement are
included herein for convenience of reference only and shall not
constitute a part of this Agreement for any other purpose or be given
any substantive effect.

     7.13 Applicable Law.  THIS AGREEMENT, EACH LOAN DOCUMENT OTHER
THAN THE MORTGAGE AND THE NOTES SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
NEW YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAW.

     7.14 Successors and Assigns; Subsequent Holders of Notes.  This
Agreement shall be binding upon the parties hereto and their
respective successors and assigns and shall inure to the benefit of
the parties hereto and the successors and assigns of the Lenders.  The
terms and provisions of this Agreement and each Loan Document shall
inure to the benefit of any assignee or transferee of the Notes
pursuant to Section 7.1, and in the event of such transfer or
assignment, the rights and privileges herein conferred upon the Lender
shall automatically extend to and be vested in such transferee or
assignee, all subject to the terms and conditions hereof.  The
Company's rights or any interest therein hereunder may not be assigned
without the prior express written consent of the Lender and the
Trustee.

     7.15 Counterparts; Effectiveness.  This Agreement and any amendments,
waivers, consents or supplements may be executed in any number of
counterparts and by different parties hereto in separate counterparts,
each of which when so executed and delivered shall be deemed an
original, but all such counterparts together shall constitute but one
and the same instrument.  This Agreement shall become effective upon
the execution of a counterpart hereof by each of the parties hereto.

     7.16 Consent to Jurisdiction; Venue; Waiver of Jury Trial.

     A. Any legal action or proceeding with respect to this Agreement, any
Note or any Loan Document may be brought in the courts of the State of
New York or of the United States for the Southern District of New
York, and, by execution and delivery of this Agreement, each of the
parties to this Agreement hereby irrevocably accepts for itself and in
respect of its respective property, generally and unconditionally, the
jurisdiction of the aforesaid courts.  Each of the parties to this
Agreement hereby further irrevocably waives any claim that any such
courts lack jurisdiction over itself, and agrees not to plead or
claim, in any legal action or proceeding with respect to this
Agreement, the Notes or Loan Documents brought in any of the aforesaid
courts, that any such court lacks jurisdiction over such party.  Each
of the parties to this Agreement irrevocably consents to the service
of process in any such action or proceeding by the mailing of copies
thereof by registered or certified mail, postage prepaid, to such
party, at its respective address for notices pursuant to Section 7.8,
such service to become effective 30 days after such mailing.  To the
extent permitted by law, each of the parties to this Agreement hereby
irrevocably waives any objection to such service of process and
further irrevocably waives and agrees not to plead or claim in any
action or proceeding commenced hereunder or under the Notes or any
Loan Document that service of process was in any way invalid or
ineffective.  Nothing herein shall affect the right of any party to
this Agreement to serve process in any other manner permitted by law
or to commence legal proceedings or otherwise proceed against any
party in any other jurisdiction.

     B. Each of the parties to this Agreement hereby irrevocably waives any
objection which it may now or hereafter have to the laying of venue of
any of the aforesaid any of actions or proceedings arising out of or
in connection with this Agreement, the Notes or any of the Loan
Documents brought in the courts referred to in clause A above and
hereby further irrevocably waives and agrees not to plead or claim in
any such court that any such action or proceeding brought in any such
court has been brought in an inconvenient forum.

     C. Each of the parties to this Agreement hereby irrevocably waives all
right to a trial by jury in any action, proceeding or counterclaim
arising out of or relating to this Agreement, the Notes or the Loan
Documents or the transactions contemplated hereby or thereby.

     7.17 Waiver of Stay, Extension or Usury Laws.  The Company covenants
(to the extent that it may lawfully do so) that it will not at any
time insist upon, plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law or any usury law or
other law that would prohibit or forgive the Company from paying all
or any portion of the principal of or interest on the Loan as
contemplated herein, wherever enacted, now or at the time hereafter in
force, or which may affect the covenants or the performance of this
Agreement and (to the extent that it may lawfully do so), the Company
hereby expressly waives all benefit or advantage of any such law, and
covenants that it will not hinder, delay or impede the execution of
any power herein granted to the Lender, but will suffer and permit the
execution of every such power as though no such law had been enacted.

     7.18 Usury Savings Clause.  It is the intention of the parties hereto
to comply with applicable usury laws (now or hereafter enacted);
accordingly, notwithstanding any provision to the contrary in this
Agreement, any Note, any of the other Loan Documents or any other
document related hereto or thereto, in no event shall this Agreement
or any such other document require the payment or permit the
collection of interest in excess of the maximum amount permitted by
such laws.  If from any circumstances whatsoever, fulfillment of any
provision of this Agreement, any Note, any of the other Loan Documents
or of any other document pertaining hereto or thereto, shall involve
transcending the limit of validity prescribed by applicable law for
the collection or charging of interest, then, ipso facto, the
obligation to be fulfilled shall be reduced to the limit of such
validity, and if from any such circumstances the Lender shall ever
receive anything of value as interest or deemed interest by applicable
law under this Agreement, any Note, any of the other Loan Documents or
any other document pertaining hereto or otherwise an amount that would
exceed the highest lawful rate, such amount that would be excessive
interest shall be applied to the reduction of the principal amount
owing under the Loan or on account of any other indebtedness of the
Company, and not to the payment of interest, or if such excessive
interest exceeds the unpaid balance of principal of such indebtedness,
such excess shall be refunded to the Company.  In determining whether
or not the interest paid or payable with respect to any indebtedness
of the Company to Lender under any specified contingency, exceeds the
highest lawful rate, the Company  and the Lender shall, to the maximum
extent permitted by applicable law, (a) characterize any non-principal
payment as an expense, fee or premium rather than as interest,
(b) exclude voluntary prepayments and the effects thereof,
(c) amortize, prorate, allocate and spread the total amount of
interest thereon does not exceed the maximum amount permitted by
applicable laws, and/or (d) allocate interest throughout the full term
of such indebtedness so that interest between portions of such
indebtedness, to the end that no such portion shall bear interest at a
rate greater than that permitted by applicable law.

authorized  officers of the undersigned as of the date  first  written
above.
