      1.5. If any of the fixed annual rent or additional rent payable under the
terms and provisions of this Lease shall be or become uncollectible, reduced or
required to be refunded because of any Legal Requirement (as such term is

restriction may be legally permissible (and not in excess of the amounts
reserved therefor under this Lease). Upon the termination of such legal rent
restriction, (a) the rents shall become and thereafter be payable in accordance
with the amounts reserved herein for the periods following such termination and
(b) Tenant shall pay to Landlord, to the maximum extent legally permissible, an
amount equal to (i) the rents which would have been paid pursuant to this Lease

      commencing on the first day of July in which occurs any part of the term
      of this Lease or such other period of twelve months occurring during the
      term of this Lease as hereafter may be duly adopted as the fiscal year for

            (b) The term "The Building Project" shall mean the parcel of land
      set forth in Exhibit A of this Lease, on a portion of which are the

<PAGE>

      (including without limitation, the office building and parking areas
      erected thereon).

            (c) The term "Comparative Year" shall mean the Tax Year commencing
      on the July 1st immediately preceding the Commencement Date and each
      subsequent Tax Year. If the present use of July 1 to June 30 Tax Year

      appropriate adjustment for the transition.

            (d) The term "Taxes" shall mean the total of all real estate and
      other taxes and special, general, extraordinary or other assessments,
      sewer rents, water charges, occupancy taxes and other taxes or charges of
      any kind or nature levied, assessed, imposed or attributable at any time
      by the City of Norwalk, the Town of Darien or any other governmental

      school district or public transportation authority) upon or against The
      Building Project, and also any tax, assessment, or charge, levied,
      assessed or imposed at any time by any governmental authority in
      connection with the receipt of income or rents from The Building Project
      to the extent that same shall be in lieu of all or a portion of any of the
      aforesaid taxes, assessments or charges, or additions or increases
      thereof. If, due to a future change in the method of taxation or in the
      taxing authority, or for any other reason, a franchise, income, transit,
      profit or other tax or governmental imposition, however designated, shall
      be levied against owners and lessors of real property (as opposed to a tax
      or imposition of general application) and the same shall be levied against
      Landlord in substitution in whole or in part for the Taxes, then such
      franchise, income, transit, profit or other tax or governmental imposition
      shall be deemed to be included within the definition of "Taxes" for the
      purposes hereof. If, by law, any assessment shall be payable in
      installments, then, for the purposes hereof (i) such assessment shall be
      deemed to have been payable in the maximum number of installments
      permitted by law and (ii) there shall be included in Taxes, for each

      premises), by reference to the notes of the applicable tax assessor; any

            (e) The term "Tax Base Factor" shall mean an amount equal to the
      Taxes for the twelve (12) month period commencing September 1, 1993. To
      the extent that the period for which the Tax Base Factor is to be
      calculated does not correspond with the fiscal year for real estate taxes
      of the jurisdiction to which the same are paid, the Tax Base Factor shall
      be calculated using a weighted average of the Taxes for the fiscal years
      in which such twelve (12) month period occurs (e.g., if the period upon
      which the Tax Base Factor is based includes ten (10) months of one fiscal
      year and two (2) months of another fiscal year, the Tax Base Factor shall
      include 10/12th of the Taxes of the former and 2/12th of the Taxes of the
      latter).

            (f) The term "The Percentage," for purposes of computing tax
      escalation pursuant to this Article, shall mean 40.83 (4O.83%) percent.
      The Percentage has been computed on the basis of a fraction, the numerator
      of which is the rentable square foot area of the demised premises and the
      denominator of which is the rentable square foot area of the office
      building comprising a part of The Building Project. The parties agree that
      the rentable square foot area of the demised premises shall be deemed to
      be 164,739 square feet and that the total rentable square foot area of the
      office building comprising a part of The Building Project shall be deemed
      to be 403,437 square feet.

            (g) The term "Tax Escalation Statement" shall mean a written
      statement (i) setting forth the amount payable by Tenant or Landlord as
      the case may be, for a specified Comparative Year pursuant to this
      Article, (ii) providing such detail as may be necessary to verify the
      basis for the calculation and inclusion of each component of such amount,
      and (iii) accompanied by copies of the tax bills from the taxing
      authorities with respect to The Building Project for the then applicable
      Tax Year(s).

      3.3. (a) In the event that the Taxes payable for any Comparative Year
shall exceed the Tax Base Factor, Tenant shall pay tax escalation to Landlord,
as additional rent for such Comparative Year, in an amount equal to The
Percentage of the excess (such amount being sometimes hereinafter called the
"Tax Escalation Payment"), subject to the provisions of Section 3.12 hereof.
Before or after the start of each Comparative Year, Landlord shall furnish to
Tenant a Tax Escalation Statement of the Taxes payable for such Comparative
Year. If 2)> the Taxes payable for such Comparative Year exceed the Tax Base
Factor, additional rent for such Comparative Year in an amount1 equal to The
Percentage of the excess shall be due from Tenant to Landlord in two equal
installments, on June 1 preceding such Comparative Year and December 1 of such
Comparative Year. If during the term of this Lease, Taxes are required to be
paid (either to the appropriate taxing authorities or as tax escrow payments to
a superior mortgagee) in full or in monthly, quarterly, or other installments,
or on any other date or dates than as presently required (Taxes are currently
due on July 1 and January 1 of each Comparative Year), then at Landlord's
option, the Tax Escalation Payments shall be correspondingly accelerated or
revised so that said Tax Escalation Payments are due 30 days prior to the

                                       5
<PAGE>

date payments are due (to the taxing authorities or the superior mortgagee). The
benefit of any discount for any early payment or prepayment of Taxes shall
accrue solely to the benefit of Landlord and such discount shall not be
subtracted from Taxes. If a Tax Escalation Statement is furnished to Tenant
after the commencement of the Comparative Year in respect of which such Tax
Escalation Statement is rendered, Tenant shall, within twenty (20) days
thereafter pay to Landlord an amount equal to those installments of the total
Tax Escalation Payment payable as provided in this subsection 3.03(a) during the
period prior to the first day of the month next succeeding the month in which
the applicable statement has been furnished.

            (b) Landlord shall be entitled to estimate the Taxes payable with
      respect to any Tax Year in order to make the computation described in
      subsection 3.03(a) above. Any excess amount paid by Tenant or any
      deficiency owed by Tenant based upon such estimate shall be repaid by
      Landlord or paid by Tenant, as the case may be, with interest thereon at
      the Interest Rate computed from the date owed to the payment or repayment
      thereof.

            (c) Tenant shall also pay to Landlord, as additional rent, the
      entire amount of increases in Taxes directly allocable to improvements
      made to the demised premises after the same has been initially improved
      for occupancy to the extent such increases can be attributed by reference
      to the notes of the tax assessor to such improvements. Payments by Tenant
      under this subsection 3.03(c) shall be made as and when Tenant's Tax
      Escalation Payment is due and payable to Landlord under subsection 3.03(a)
      hereof.

      3.4. If, after Tenant shall have made a payment of additional rent under
this Article, the Taxes payable for any Comparative Year on which such payment
of additional rent shall have been based shall be changed, then the amount
payable for that Comparative Year shall be revised to reflect such change and
appropriate adjustments promptly made between Landlord and Tenant. If, after
Tenant shall have made a payment of additional rent under this Article, Landlord
shall receive a refund of any portion of the Taxes payable for any Comparative
Year on which such payment of additional rent shall have been based, as a result
of a reduction of such Taxes by final determination of legal proceedings,
settlement or otherwise, Landlord shall within forty five (45) days after
receiving the refund pay to Tenant and/or credit against the installment(s) of
fixed annual rent and additional rent becoming due during such forty five (45)
day period The Percentage of the net refund, i.e., the amount of the refund less
the reasonable or customary expenses, including payments to attorneys,
appraisers and other experts, incurred by Landlord in connection with such
refund. Only Landlord shall be eligible to institute tax reduction or other
proceedings to reduce the assessed valuation of the Land and the Building.

      3.5. The Tax Escalation Statements to be furnished by Landlord as provided
in this Article shall constitute a final determination as between Landlord and
Tenant of the Tax Escalation Payment for the periods represented thereby unless
Tenant shall, within ninety (90) days after they are furnished, give a notice to
Landlord that it disputes their

                                       6
<PAGE>

accuracy or their appropriateness which notice shall specify the particular
respects in which the Tax Escalation Statement is inaccurate or inappropriate.
Pending the resolution of such dispute, Tenant shall pay additional rent to
Landlord in accordance with the Tax Escalation Statement furnished by Landlord.
Any amounts finally determined in connection with such a dispute to be owed to
Landlord or Tenant as the case may be shall be paid by the applicable party to
the other together with interest thereon at the Interest Rate computed from the
date owed to the payment thereof.

      3.6. In no event shall the fixed annual rent under this Lease be reduced
by virtue of this Article.

      3.7. If the Commencement Date is not the first day of a Comparative Year,
then the additional rent due hereunder for such Comparative Year shall be a
proportionate share of the additional rent for the entire Comparative Year, said
proportionate share to be based upon the length of time that the term of this
Lease shall have been in existence during such Comparative Year. Upon the date
of any expiration or termination of this Lease, (except termination because of
Tenant's default), whether the same be the date hereinabove set forth for the
expiration of the term or any prior or subsequent date, a proportionate share of
said additional rent for the Comparative Year during which such expiration or
termination occurs shall immediately become due and payable by Tenant to
Landlord, if it was not theretofore already billed and paid. Such proportionate
share shall be based upon the length of time that this Lease shall have been in
existence during such Comparative Year. Prior to or promptly after said
expiration or termination, Landlord shall compute the additional rent due from
Tenant, as aforesaid, and Landlord and Tenant shall thereupon make' appropriate
adjustments of amounts then owing.

      3.8. Landlord's and Tenant's obligation to make the adjustments referred
to in Section 3.07 hereof above shall survive any expiration or termination of
this Lease. After the termination of the Lease, the final adjustment for Tax
Escalation pursuant to this Article 3 shall be made as soon as practicable, and
if Landlord retains any moneys of Tenant due to excess payments made by Tenant
hereunder, such excess moneys shall be promptly refunded to Tenant after such
final adjustment has been made with interest thereon if and to the extent that
Section 1.04(b) hereof is applicable thereto.

      3.9. Any delay or failure of Landlord to bill any Tax Escalation Payment
as provided in this Article 3 shall not constitute a waiver of or in any way
impair the continuing obligation of Tenant to make such Tax Escalation Payment,
unless such delay or failure shall continue for more than two (2) years after
the end of the Comparative Year in which such Tax Escalation Payment became due
and payable by Tenant, and thereafter Tenant shall have given Landlord a notice
stating that unless Tenant receives such billing from Landlord within thirty
(30) days from the date of such notice (and such billing is not received within
such thirty (30) day period), such additional Tax Escalation Payment shall be
deemed to have been waived.

      3.10. Landlord shall advise Tenant by notice (hereinafter called the "Tax
Contest Notice") within sixty (60) days after any new assessment or reassessment
by the

                                       7
<PAGE>

City of Norwalk increasing the assessed value of The Building Project
(hereinafter called the "New Assessed Value") whether Landlord intends to
contest such new assessment or reassessment. If Landlord advises Tenant that
Landlord does not intend to contest such new assessment or reassessment,
Landlord agrees that if Tenant shall, at Tenant's sole cost and expense, obtain
and deliver to Landlord within sixty (60) days after the date of the Tax Contest
Notice, an appraisal of The Building Project by a member of the American
Institute of Real Estate Appraisers (or any successor association or body of
comparable standing if such institute is not then in existence) reasonably
acceptable to Landlord, showing that the New Assessed Value determined by the
taxing authorities is more than twelve (12%) percent in excess of what it should
be, then Landlord shall contest such reassessment or new assessment of the New
Assessed Value.

      3.11. (a) Tenant shall pay to Landlord, within twenty (20) days after
Landlord's demand therefor, an amount equal to the reasonable or customary
expenses, including payments to attorneys, appraisers and other experts,
incurred by Landlord in connection with any contest pursuant to Section 3.10
hereof; however, if Landlord shall receive any refund in Taxes as a result of
such contest, Landlord shall, before making any credits or refunds therefrom to
any tenant in the Building, reimburse Tenant (to the extent that such refund or
credit is sufficient therof or) for the expenses paid by Tenant pursuant to this
Section 3.11 and the reasonable expenses incurred by Tenant in obtaining the
appraisal described in Section 3.10 hereof.

            (b) If Landlord shall obtain a reduction of Taxes payable upon or
      against The Building Project for any Comparative Year before Tenant shall
      make Tax Escalation Payments therefor, the Taxes for such Comparative Year
      for the purposes of computing Tenant's Tax Escalation Payment shall
      include an amount equal to the reasonable and customary expenses,
      including payments to attorneys, appraisers and other experts incurred by
      Landlord in obtaining such reduction, but in no event shall the aggregate
      of such expenses included within Taxes as provided herein exceed the
      amount of the reduction obtained thereby.

      3.12. (a) For purposes of this Section 3.12, the following terms shall
have the meanings hereinafter set forth:

            (i) "The First Floor West and Fourth Floor North Percentage" shall
      mean 10.56%;

            (ii) "The Remaining Floors Percentage" shall mean 30.27%; and

            (iii) "Modified Tax Base Factor" shall mean an amount equal to the
      Taxes for the twelve (12) month period commencing on July 1, 1992.

The First Floor West and Fourth Floor North Percentage and the Remaining Floors
Percentage have been computed on the basis of a fraction, the numerator of which
is the rentable square foot area of the First Floor West and Fourth Floor North
portion of the demised premises and the remaining portion of the demised
premises, respectively, and

                                       8
<PAGE>

the denominator of which is the rentable square foot area of the office building
comprising a part of The Building Project. The parties agree that the rentable
square foot area of the First Floor West and Fourth Floor North portion of the
demised premises and the remaining portion of the demised premises shall be
deemed to be 42,609 square feet and 122,130 square feet, respectively, and that
the total rentable square foot area of the office building comprising a part of
The Building Project shall be deemed to be 403,437 square feet.

            (b) Notwithstanding anything to the contrary in this Article 3,
      during the period commencing on the Commencement Date and ending on
      February 29, 1996, the Tax Escalation Payment shall be the sum of:

                  (i) The First Floor West and Fourth Floor North Percentage of
            the excess of the Taxes payable for any Comparative Year over the
            Tax Base Factor; and

                  (ii) The Remaining Floors Percentage of the excess of the
            Taxes payable for any Comparative Year over the Modified Tax Base
            Factor.

            (c) The Tax Escalation Payment for the Comparative Year commencing
      on July 1, 1995 (or such other Comparative Year in which March 1, 1996
      occurs) shall be equal to the sum of (i) the Tax Escalation Payment,
      calculated as provided in this Section 3.12, for the period commencing on
      July 1, 1995 and ending on February 29, 1996, and (ii) the Tax Escalation
      Payment, calculated as otherwise provided in this Article 3 (and without
      reference to the Modified Tax Base Factor), for the balance of such
      Comparative Year. The Tax Escalation Payments for the Comparative Year
      commencing July 1, 1996 and all Comparative Years thereafter shall be
      computed utilizing the Tax Base Factor only and without regard to the
      Modified Tax Base Factor.

                                    ARTICLE 4

definitions shall apply:

            (a) The term "Expense Base Factor" shall mean the Expenses for the
      twelve (12) month period commencing September 1, 1993. To the extent that

      Expenses with respect to

                                       9
<PAGE>

      The Building Project, the Expense Base Factor shall be calculated using a
      weighted average of the Expenses for the fiscal years in which such twelve
      (12) month period occurs (e.g., if the period upon which the Expense Base
      Factor is based includes eight (8) months of one fiscal year and four (4)
      months of another fiscal year, the Expense Base Factor shall include
      8/12th of the Expenses of the former and 4/12th of the Expenses of the
      latter).

      described in Exhibit A of this Lease, on a portion of which are the
      improvements of which the demised premises form a part, with all the
      improvements thereon (including without limitations, the office building
      and parking areas erected thereon).

            (c) The term "Comparative Year" shall mean the full calendar year in

      computed on the basis of a fraction, the numerator of which is the
      rentable square foot area of the demised premises and the denominator of
      which is the total rentable square foot area of the office building
      comprising a part of The Building Project. The parties agree that the
      rentable square foot area of the demised premises shall be deemed to be
      164,739 and that the total rentable square foot area of the office
      building comprising a part of The Building Project shall be deemed to be
      403,437 square feet.

            (e) The term "Expense Escalation Statement" shall mean a written
      statement setting forth the amount payable by Tenant or Landlord, as the
      case may be, for a specified Comparative Year pursuant to this Article.

            (f) The term "Expenses" shall mean the total amount of all costs and
      expenses incurred or paid by Landlord with respect to and in connection

      nature shall be included in the Expense Base Factor); all other costs and
      expenses of operation and maintenance of The Building Project; auditing

            exceeding those which a prudent landlord would maintain under the
            circumstances), or caused by the exercise of the right of eminent
            domain;

                  (iv) except as provided in clause (ii) hereof, interest on and

            ownership with Landlord, but only to the extent of the excess paid
            to such entity over that which would have been paid in the absence
            of such a relationship;

                                       12
<PAGE>

                  (xv) costs or expenses for which Landlord has been
            specifically reimbursed by any tenant, including Tenant, other than
            by payment of a portion of Landlord's operating expenses generally
            or pursuant to any other escalation or similar provision of such
            tenant's lease, or any other party;

                  (xvi) any penalty or fine incurred for non compliance with

                  (xviii) franchise, income or other taxes or assessments,
            penalties or fines imposed upon Landlord (excluding taxes payable
            with respect to costs and expenses comprising Expenses); and

                  (xix) the salaries or other compensation of employees of
            Landlord above the level of Building manager.

      If Landlord shall purchase any item of capital equipment or make any
      capital expenditures designed to result in savings or reductions in
      Expenses, then the costs for same shall be included in Expenses for the
      Comparative Year in which the costs are incurred and subsequent
      Comparative Years, on a straight line basis, to the extent that such items
      are amortized over such period of time as reasonably can be estimated as
      the time in which such savings or reductions in Expenses are expected to
      equal Landlord's costs for such capital equipment or capital expenditure,
      with an interest factor equal to the Interest Rate at the time of
      Landlord's having incurred said costs. If Landlord shall lease any such
      item of capital equipment designed to result in savings or reductions in
      Expenses, then the rentals and other costs paid pursuant to such leasing
      shall be included in expenses for the Comparative Years in which they were
      incurred, provided that the charges for any such lease shall be
      essentially constant throughout the term thereof and shall not for any
      Comparative Year exceed the reasonably anticipated savings to be realized
      therefrom.

      If during all or part of any Comparative Year, or any calendar year on
      which the Expense Base Factor or Modified Expense Base Factor is based,
      Landlord shall not furnish any particular item(s) of work or service
      (which would constitute an element of Expense hereunder) to portions of
      The Building Project due to the fact that such portions are not occupied
      or leased, or because such item of work or service is not required or
      desired by the tenant of such portion, or such tenant is itself obtaining
      and providing such item of work or service, or for other reasons, then,
      for the purposes of computing the additional rent payable hereunder, the
      amount of the expenses for such item for such period shall be deemed to be
      increased by an amount equal to the additional operating and maintenance
      expenses which would reasonably have been incurred during such period by

                                       13
<PAGE>

      Landlord if it had at its own expense furnished such item of work or
      services to ninety five (95%) percent of the rentable area of The Building
      Project.

      4.3. (a) If the Expenses for any Comparative Year shall be greater than
the Expense Base Factor, Tenant shall pay to Landlord, as additional rent for
such Comparative Year, in the manner hereinafter provided, an amount equal to
The Percentage of the excess of the Expenses for such Comparative Year over the
Expense Base Factor (such amount being hereinafter called the "Expense
Payment"), subject to the provisions of Section 4.08 hereof.

            (b) Following the expiration of each Comparative Year, Landlord
      shall submit to Tenant an Expense Escalation Statement, certified by
      Landlord, setting forth the Expenses for the preceding Comparative Year
      and the Expense Payment, if any, due to Landlord from Tenant for such
      Comparative Year. The rendition of such Expense Escalation Statement to
      Tenant shall constitute prima facie proof of the accuracy thereof and, if
      such statement shows an Expense Payment due from Tenant to Landlord with
      respect to the preceding Comparative Year then (i) Tenant shall make
      payment of any unpaid portion thereof within twenty (20) days after
      receipt of such Expense Escalation Statement; and (ii) Tenant shall also
      pay to Landlord, as additional rent, within twenty (20) days after receipt
      of such Expense Escalation Statement, an amount equal to the product
      obtained by multiplying the total Expense Payment for the preceding
      Comparative Year by a fraction, the denominator of which shall be 12 and
      the numerator of which shall be the number of months of the current
      Comparative Year which shall have elapsed prior to the first day of the
      month immediately following the rendition of such Expense Escalation
      Statement; and (iii) Tenant shall also pay to Landlord, as additional
      rent, commencing as of the first day of the month immediately following
      the rendition of such Expense Escalation Statement and on the first day of
      each month thereafter until a new Expense Escalation Statement is
      rendered, 1/12th of the total Expense Payment for the preceding
      Comparative Year. The aforesaid monthly payments based on the total
      Expense Payment for the preceding Comparative Year shall be adjusted to
      reflect, as reasonably estimated and specifically set forth in reasonable
      detail in such Expense Escalation Statement by Landlord, increases in
      rates and amounts, for the current Comparative Year, applicable to the
      categories involved in computing Expenses, whenever such increases become
      reasonably known or anticipated prior to or during such current
      Comparative Year. The payments required to be made under clauses (ii) and
      (iii) of this subsection 4.03(b) shall be credited toward the Expense
      Payment due from Tenant for the then current Comparative Year, subject to
      adjustment as and when the Expense Escalation Statement for such current
      Comparative Year is rendered by Landlord.

            (c) The Expense Escalation Statements to be furnished by Landlord
      shall constitute a final determination as between Landlord and Tenant of
      the Expense Payments for the periods represented thereby, unless Tenant
      within one hundred (100) days after they are furnished shall give a notice
      to Landlord that it

                                       14
<PAGE>

      disputes their accuracy or their appropriateness, which notice shall
      specify the particular respects in which the Expense Escalation Statement
      is inaccurate. Pending the resolution of such dispute, Tenant shall pay
      the additional rent to Landlord in accordance with the Expense Escalation
      Statements furnished by Landlord. After payment of said additional rent,
      Tenant shall have the right, during reasonable business hours and upon not
      less than five (5) business days' prior written notice to Landlord, to
      examine Landlord's books and records with respect to the foregoing
      provided such examination is commenced within sixty (60) days and
      concluded within one hundred twenty five (125) days following the
      rendition of the Expense Escalation Statement in question. Any amounts
      finally determined in connection with such a dispute to be owed to
      Landlord or Tenant, as the case may be, shall be paid by the applicable
      party to the other together with interest thereon at the Interest Rate
      computed from the date owed to the payment thereof.

      4.4. In no event shall the fixed annual rent under this Lease be reduced
by virtue of this Article.

      4.5. If the Commencement Date is not the first day of the first
Comparative Year, then the additional rent due hereunder for such first
Comparative Year shall be a proportionate share of said additional rent for the
entire Comparative Year, said proportionate share to be based upon the length of
time that the Lease term shall have been in existence during such first
Comparative Year. Upon the date of any expiration or termination of this Lease
(except termination because of Tenant's default), whether the same be the date
hereinabove set forth for the expiration of the term or any prior or subsequent
date, a proportionate share of said additional rent for the Comparative Year
during which such expiration or termination occurs shall immediately become due
and payable by Tenant to Landlord, if it was not theretofore already billed and
paid. The said proportionate share shall be based upon the length of time that
this Lease shall have been in existence during such Comparative Year. Landlord
shall cause an Expense Escalation Statement for that Comparative Year to be
prepared and furnished to Tenant. Landlord and Tenant shall thereupon make
appropriate adjustments of amounts then owing.

      4.6. Landlord's and Tenant's obligation to make the adjustments referred
to in Section 4.05 hereof shall survive any expiration or termination of this
Lease.

      4.7. Any delay or failure of Landlord in billing any Expense Payment
hereinabove provided shall not constitute a waiver of or in any way impair the
continuing obligation of Tenant to pay such expense escalation hereunder, unless
such delay or failure shall continue for more than two (2) years after the end
of the Comparative Year in which such Expense Payment became due and payable by
Tenant, and thereafter Tenant shall have given Landlord a notice stating that
unless Tenant receives such billing from Landlord within thirty (30) days from
the date of such notice (and such billing is not received within such thirty
(30) day period), such Expense Payment, to the extent not theretofore paid,
shall be deemed to have been waived.

      4.8. (a) For purposes of this Section 4.08, the following terms shall have
the meanings hereinafter set forth:

            (i) "The First Floor West and Fourth Floor North Percentage" shall
      mean 10.56%;

            (ii) "The Remaining Floors Percentage" shall mean 30.27%; and

            (iii) "Modified Expense Base Factor" shall mean an amount equal to
      the Expenses for the twelve (12) month period commencing on July 1, 1992.

The First Floor West and Fourth Floor North Percentage and the Remaining Floors
Percentage have been computed on the basis of a fraction, the numerator of which
is the rentable square foot area of the First Floor West and Fourth Floor North
portion of the demised premises and the remaining portion of the demised
premises, respectively, and the denominator of which is the rentable square foot
area of the office building comprising a part of The Building Project. The
parties agree that the rentable square foot area of the First Floor West and
Fourth Floor North portion of the demised premises and the remaining portion of
the demised premises shall be deemed to be 42,609 square feet and 122,130 square
feet, respectively, and that the total rentable square foot area of the office
building comprising a part of The Building Project shall be deemed to be 403,437
square feet.

            (a) Notwithstanding anything to the contrary in this Article 4,
      during the period commencing on the Commencement Date and ending on
      February 29, 1996, the Expense Payment shall be the sum of:

                  (i) The First Floor West and Fourth Floor North Percentage of
            the excess of the Expenses payable for any Comparative Year over the
            Expense Base Factor; and

                  (ii) The Remaining Floors Percentage of the excess of the
            Expenses for any Comparative Year over the Modified Expense Base
            Factor.

      4.9. The Expense Payment for the Comparative Year commencing on January 1,
1996 (or such other Comparative Year in which March 1, 1996 occurs) shall be
equal to the sum of (i) the Expense Payment, calculated as provided in this
Section 4.08, for the period commencing on January 1, 1996 and ending on
February 29, 1996, and (ii) the Expense Payment, calculated as otherwise
provided in this Article 4 (and without reference to the Modified Expense Base
Factor), for the balance of such Comparative Year. The Expense Payments for the
Comparative Year commencing January 1, 1997 and all Comparative Years thereafter
shall be computed utilizing the Expense Base Factor only and without regard to
the Modified Expense Base Factor.

                                       USE

      5.1. The demised premises shall be used solely as and for executive and
general offices and other business activities customarily incidental thereto in
first class office buildings in Fairfield County, Connecticut and, as an
incident thereto, a portion of the demised premises may be used as an exercise
facility or gym exclusively for Tenant's employees, such use to be limited to a
portion of the demised premises of approximately 5,000 rentable square feet and
located on the First C 1st) Floor West of the Building (hereinafter referred to
as the "Exercise Facility") and for no other purposes.

      5.2. Tenant shall not use or permit the use of the demised premises or any
part thereof in any way which would violate any of the covenants, agreements,
terms, provisions and conditions of this Lease or for any unlawful purposes or
in any unlawful manner or in violation of the certificate of occupancy or other
certificate or permit for the demised premises or the Building, and Tenant shall
not suffer or permit the demised premises or any part thereof to be used in any
manner or anything to be done therein or anything to be brought into or kept
therein which, in the reasonable judgment of Landlord, shall in any way impair
the character, reputation or appearance of the Building as a high quality office
building, impair or interfere with any of the Building services or the proper
and economic heating, cleaning, air conditioning or other servicing of the
Building or the demised premises, or impair or interfere with the use of any of
the other areas of the Building by, or occasion discomfort, inconvenience or
annoyance to, any of the other tenants or occupants of the Building. Tenant
shall not install any electrical or other equipment of any kind which, in the
reasonable judgment of Landlord, might cause any impairment or interference with
the operation of electrical equipment installed elsewhere in the Building.

                                    ARTICLE 6

                          ALTERATIONS AND INSTALLATIONS

      6.1.  (a) Tenant shall make no alterations, installations, additions or
            improvements (such work hereinafter collectively referred to as
            "Alterations") in or to the demised premises without Landlord's
            prior written consent and then only by contractors or mechanics
            first approved by Landlord. Notwithstanding the foregoing,
            Landlord's consent shall not be required for non structural
            Alterations in the demised premises costing less than the "Threshold
            Amount" (as such term is hereinafter defined), provided that (i)
            neither the outside appearance, nor the strength of the Building,
            nor any of its structural parts shall be affected; (ii) no part of
            the Building outside of the demised premises shall be physically
            affected, (iii) the proper functioning of any of the mechanical,
            electrical, sanitary and other systems of the Building shall not be
            adversely affected, and the usage of such systems by Tenant shall
            not be increased

                                       17
<PAGE>

            except to a de minimis extent, and (iv) prior to commencement of any
            such Alterations, Tenant will give Landlord written notice thereof,
            together with plans and specifications for the work, and will
            otherwise comply with the provisions of this Article. As used in
            this Section 6.01, the term "Threshold Amount" shall mean $100,000
            effective as of the Commencement Date, which amount shall be
            increased effective as of each anniversary of the Commencement Date
            by $5,000. All such Alterations, shall be done at Tenant's sole
            expense and at such times and in such manner as Landlord may from
            time to time reasonably designate. Prior to commencement of
            Alterations, other than Alterations performed to prepare the demised
            premises for Tenant's initial occupancy or Alterations costing less
            than $150,000.00, Tenant shall obtain and deliver to Landlord (i)
            written, unconditional waivers of mechanic's or other liens on the
            real property in which the demised premises are located, signed by
            all architects, engineers, contractors, mechanics and designers to
            become involved in such Alterations (ii) a bond or other security
            reasonably satisfactory to Landlord covering the cost or (iii) proof
            of Tenant's financial responsibility (i.e., financial capacity to
            complete the same and pay therefor) reasonably satisfactory to
            Landlord.

            (b) Tenant's Alterations shall be effected solely in accordance with
      plans and specifications delivered to Landlord or if the Alterations are
      of such a nature that plans and specifications are not customary then upon
      prior notice to Landlord. Tenant shall reimburse Landlord promptly upon
      demand for any reasonable out of pocket costs and expenses incurred by
      Landlord in connection with Landlord's review of such Tenant's plans and
      specifications. As to Alterations for which Landlord's approval is
      required, (i) Landlord will not unreasonably withhold or delay its consent
      for nonstructural Alterations (provided they will not affect the outside
      of the Building or adversely affect the Building's structure, electrical,
      HVAC, plumbing or mechanical systems) and (ii) all such Alterations shall
      be solely effected in accordance with plans and specifications approved by
      Landlord (except that de minimis variations therefrom shall not de deemed
      a violation hereof). Landlord hereby approves Tenant's installation of
      operating windows in the area of the demised premises indicated in the
      plans annexed hereto as Exhibit J provided same is performed in accordance
      with the provisions hereof and such windows are, in Landlord's reasonable
      judgment, consistent in appearance and quality with the adjacent windows
      of the Building.

            (c) Any such approved Alterations shall be performed in accordance
      with the foregoing and the following provisions of this Article 6:

                  (1) All Alterations shall be done in a good and workmanlike
            manner.

                  (2) (A) In the event Tenant shall employ any contractor to do
            in the demised premises any Alterations permitted by this Lease,
            such contractor and any subcontractor shall agree to employ only
            such labor as will not result in jurisdictional disputes or strikes
            or result in causing disharmony with other workers employed at the
            Building. Tenant will inform Landlord in writing of the names of any
            contractor or subcontractor Tenant proposes to use in the demised
            premises at least ten (10) days prior to the beginning of work by
            such contractor or subcontractor, but such information given to
            Landlord shall in no way constitute Landlord's approval of such
            contractor or subcontractor.

                  (B) Tenant covenants and agrees to pay to the contractors, as
            the work progresses, the entire cost of supplying the materials and
            performing the work shown on Tenant's approved plans and
            specifications except with respect to such portion of any
            contractor's work which is being contested by Tenant in good faith.

               (3) All such Alterations shall be effected in compliance with all
          applicable laws, ordinances, rules and regulations of governmental
          bodies having or asserting jurisdiction in the demised premises.
          Tenant shall also be responsible for obtaining all Building Department
          sign-offs, inspection certificates and any permits required to be
          issued by any governmental entity having jurisdiction thereover. As
          and when required by law, Landlord shall reasonably cooperate with
          Tenant in obtaining such sign-offs, inspection certificates and
          permits provided Landlord shall not incur any liability or expense
          thereby.

               (4) Tenant shall keep the Building and the demised premises free
          and clear of all liens for any work or material claimed to have been
          furnished to Tenant or to the demised premises on Tenant's behalf, and
          all work to be performed by Tenant shall be done in a manner which
          will not unreasonably interfere with or disturb other tenants or
          occupants of the Building.

               (5) During the progress of the work to be done by Tenant, said
          work shall be subject to inspection by representatives of Landlord
          which shall be permitted access and the opportunity to inspect, at all
          reasonable times, but this provision shall not in any way whatsoever
          create any obligation on Landlord to conduct such an inspection or
          create any obligations or liability (or relieve Tenant of any
          obligations under this Lease) in the event Landlord does conduct such
          an inspection.

               (6) Prior to commencement of any work, Tenant shall furnish to
          Landlord certificates evidencing the existence of:

                                       19
<PAGE>

                  (i) worker's compensation insurance covering all persons
            employed for such work; and

                  (ii) reasonable comprehensive general liability and property
            damage insurance naming Landlord, its designees and Tenant as
            insureds, with coverage of at least $3,000,000 combined single
            limit.

Notice is hereby given that Landlord shall not be liable for any labor or
materials furnished or to be furnished to Tenant upon credit, and that no
mechanic's or other lien for any such labor or materials shall attach to or
affect the reversion or other estate or interest of Landlord in and to the
demised premises.

      6.2. Any mechanic's lien, filed against the demised premises or the
Building for work claimed to have been done for or materials claimed to have
been furnished to Tenant shall be discharged by Tenant at its expense within
thirty C30) days after notice of such filing, by payment, filing of the bond
required by law or otherwise.

      6.3. All Alterations made and installed by Landlord shall be the property
of Landlord and shall remain upon and be surrendered with the demised premises
as a part thereof at the end of the term of this Lease.

      6.4. All Alterations, including, without limitation, any interior
staircases, elevators or operable windows, made and installed by Tenant, or at
Tenant's expense, upon or in the demised premises which are of a permanent
nature and which cannot be removed without damage to the demised premises or
Building shall become and be the property of Landlord, and shall remain upon and
be surrendered with the demised premises as a part thereof at the end of the
term of this Lease, except that Landlord shall have the right 'and privilege at
any time up to six (6) months prior to the expiration of the term of the Lease
to serve notice upon Tenant that any of such Alterations which is of a non
building standard nature (hereinafter called a "Non Standard Alteration"),
including operable windows, stairways, lifts or elevators, vaults, raised floors
or other structural supports and other installations which are unusually
difficult or costly to remove, shall be removed and, in the event of service of
such notice, Tenant will, at Tenant's cost and expense not to exceed
$150,000.00, remove the same in accordance with such request, and restore the
affected portion(s) of the demised premises to their original condition,
ordinary wear and tear and casualty excepted. Notwithstanding the foregoing,
Landlord may not require Tenant to remove any Non Standard Alteration if (i)
Tenant's request for Landlord's consent to such Non Standard Alteration (x)
makes specific reference to the provisions set forth in this sentence and (y)
requests Landlord to advise Tenant whether Landlord wishes to reserve its right
to require Tenant to remove the same and (ii) Landlord's right to such removal
is not expressly reserved in Landlord's consent to said Non--Standard
Alteration.

      6.5. Where furnished by or at the expense of Tenant all furniture,
furnishings and trade fixtures, including without limitation, murals, business
machines and equip-

                                       20
<PAGE>

ment, counters, screens, grille work, special paneled doors, cages, partitions,
metal railings, closets, paneling, lighting fixtures and equipment, drinking
fountains, refrigeration and air handling equipment, and any other movable
property shall remain the property of Tenant which may at its option remove all
or any part thereof at any time prior to the expiration of the term of this
Lease. In case Tenant shall decide not to remove any part of such property,
Tenant shall notify Landlord in writing not less than three C3) months prior to
the expiration of the term of this Lease, specifying the items of property which
it has decided not to remove. If, within thirty C30) days after the service of
such notice, Landlord shall request Tenant to remove any of the said property,
Tenant shall at its expense remove the same in accordance with such request. As
to such property which Landlord does not request Tenant to remove, the same
shall be, if left by Tenant, deemed abandoned by Tenant and thereupon the same
shall become the property of Landlord.

      6.6. If any Alterations or other property which Tenant shall have the
right to remove or be requested by Landlord to remove as provided in Sections
6.04 and 6.05 hereof (herein in this Section 6.06 called the "Property") are not
removed on or prior to the expiration of the term of this Lease, Landlord shall
have the right to remove the Property and to dispose of the same without
accountability to Tenant and at the sole cost and expense of Tenant. In case of
any damage to the demised premises or the Building resulting from the removal of
the Property, Tenant shall repair such damage or, in default thereof, shall
reimburse Landlord for Landlord's cost in repairing such damage. This obligation
shall survive any termination of this Lease.

      6.7. Tenant shall keep records of Tenant's Alterations, costing in excess
of $5,000, and of the cost thereof. Tenant shall, within 45 days after demand by
Landlord, furnish to Landlord copies of such records and cost if Landlord shall
require same in connection with any proceeding to reduce the assessed valuation
of the Building or any other tax or charge, or in connection with any proceeding
instituted pursuant to Article 13 hereof.

                                    ARTICLE 7

                                     REPAIRS

      7.1. Tenant shall, at its sole cost and expense, make such repairs to the
demised premises and the fixtures and appurtenances therein as are necessitated
by the act, omission, occupancy or negligence of Tenant or by normal wear and
tear or by the use of the demised premises in a manner contrary to the purposes
for which same are leased to Tenant or the performance of Alterations by or for
Tenant, as and when needed to preserve them in good working order and condition.
Except as otherwise provided in Section 9.04 hereof, all damage or injury to the
demised premises and to its fixtures, appurtenances and equipment or to the
Building or to its fixtures, appurtenances and equipment caused by Tenant moving
property in or out of the Building or by installation or removal of furniture,
fixtures or other property, shall be repaired, restored or replaced promptly by
Tenant at its sole cost and expense, which repairs, restorations and
replacements shall be in quality and class equal to the original work or
installations but Tenant

                                       21
<PAGE>

shall not be responsible and Landlord shall be responsible for any such repairs,
restorations or replacements as are required by Landlord's negligence or willful
misconduct except to the extent that Tenant shall be compensated therefor by the
proceeds of insurance or would be compensated thereof or if it had obtained the
insurance coverage required under Article 9 hereof. If Tenant fails to make such
repairs, restoration or replacements for which Tenant is responsible hereunder,
then, upon ten (10) days prior notice (except that no such notice shall be
required in case of an emergency), same may be made by Landlord at the expense
of Tenant and such expense shall be collectible as additional rent and shall be
paid by Tenant within 20 days after rendition of a bill therefor.

The exterior walls of the Building, the portions of any window sills outside the
windows, and the windows are not part of the premises demised by this Lease and
Landlord reserves all rights to such parts of the Building.

      7.2. Tenant shall not place a load upon any floor of the demised premises
exceeding the floor load per square foot area which such floor was designed to
carry (i.e. 100 pounds per square foot live load on the ground floor and 50
pounds per square foot live load and 20 pounds per square foot dead load on all
other floors) and which is allowed by law, and if Tenant shall desire a floor
load in excess of such floor load, Landlord agrees (provided Landlord's
architects, in their sole discretion, find that the work necessary to increase
such floor load does not adversely affect the structure of the Building, and
further provided that such work will not interfere with the amount or
availability of any space adjoining alongside, above or below the demised
premises, or interfere with the occupancy of other tenants in the Building), to
strengthen and reinforce the same so as to give the live load desired, provided
Tenant shall submit to Landlord the plans showing the locations of and the
desired floor live load for the areas in question and provided further that
Tenant shall agree to pay for or reimburse Landlord on demand for the cost of
such strengthening and reinforcement as well as any other costs to and expenses
of Landlord occasioned by or resulting from such strengthening or reinforcement.

      7.3. Business machines and mechanical equipment used by Tenant which cause
vibration, noise, cold or heat that may be transmitted to the Building structure
or to any leased space to such a degree as to be objectionable to Landlord or to
any other tenant in the Building shall be placed and maintained by Tenant at its
expense in settings of cork, rubber or spring type vibration eliminators
sufficient to absorb and prevent such vibration or noise, or prevent
transmission of such cold or heat. The parties hereto recognize that the
operation of elevators, air conditioning and heating equipment may cause some
vibration, noise, heat or cold which may be transmitted to other parts of the
Building and demised premises. Landlord shall be under no obligation to endeavor
to reduce such vibration, noise, heat or cold beyond what is customary in
current good building practice for buildings of the same type as the Building.

      7.4. Except as otherwise specifically provided in this Lease, there shall
be no allowance to Tenant for a diminution of rental value and no liability on
the part of

                                       22
<PAGE>

Landlord by reason of inconvenience, annoyance or injury to business arising
from the making of any repairs, alterations, additions or improvements in or to
any portion of the Building or the demised premises or in or to fixtures,
appurtenances or equipment thereof. Landlord shall exercise reasonable diligence
(which shall include consultation with Tenant) in making any such repairs,
alterations, additions or improvements so as to minimize any interference with
Tenant's business operations, but shall not be required to perform the same on
an overtime or premium pay basis.

      7.5. Landlord shall, at its expense (subject to reimbursement pursuant to
the provisions of Article 4 hereof) keep and maintain the Building Project,
including the landscaping of the Land and its fixtures, appurtenances and
facilities serving the demised premises, including but not limited to, the
parking areas utilized by Tenant, the roof of the demised premises and the
atrium portion of the Building and the structure immediately adjacent or
contiguous to the demised premises, the electrical, heating, ventilation, air
conditioning, plumbing and mechanical systems (including heat pumps) directly
serving the demised premises to the main distribution duct serving the demised
premises (i.e., those portions of such systems that service parts of the
Building other than or in addition to the demised premises), and the windows of
the demised premises, in good condition and repair in accordance with the
standards appropriate to a first class office building in Fairfield County,
Connecticut, and make all repairs, restorations and replacements, structural and
otherwise, interior and exterior, as and when needed in or about the demised
premises, except for those repairs for which Tenant is responsible pursuant to
the provisions of this Lease.

      7.6. Except in case of emergency, Landlord shall give Tenant at least
seven (7) days prior notice of any entry, repair, alteration, addition or
improvement by Landlord under this Article 7 or Article 10 or 15 hereof, which

business in the demised premises.

                                    ARTICLE 8

                               REQUIREMENTS OF LAW

      8.1. Tenant shall, at Tenant's sole cost and expense, comply with all
laws, orders and regulations of federal, state, county and municipal
authorities, and with any direction of any public officer or officers, pursuant
to law, which shall impose any violation, order or duty upon Landlord or Tenant
with respect to the demised premises, or the use or occupation thereof. Nothing
contained in this Section 8.01 shall require Tenant to perform structural
alterations in or to the demised premises the requirement for which does not
arise from Tenant's use or manner of use of the demised premises. Such
structural alterations for which Tenant is not responsible hereunder shall be
the responsibility of Landlord.

      8.2. Notwithstanding the provisions of Section 8.01 hereof, Tenant, at its
own cost and expense, in its name and/or (whenever necessary) Landlord's name,
may contest, in any manner permitted by law (including appeals to a court, or
governmental depart-

                                       23
<PAGE>

ment or authority having jurisdiction in the matter), the validity or the
enforcement of any governmental act, regulation or directive with which Tenant
is required to comply pursuant to this Lease, and may defer compliance therewith
provided that:

            (a) such non compliance shall not subject Landlord to criminal
      prosecution or subject the Land and/or Building to lien or sale;

            (b) such non compliance shall not be in violation of any fee
      mortgage, or of any ground or underlying lease or any mortgage thereon;

            (c) Tenant shall first deliver to Landlord a surety bond issued by a
      surety company of recognized responsibility, or other security
      satisfactory to Landlord, indemnifying and protecting Landlord against any
      loss or injury by reason of such non--compliance; and

            (d) Tenant shall promptly and diligently prosecute such contest.

            Landlord, without expense or liability to it, shall cooperate with
      Tenant and execute any documents or pleadings required for such purpose,
      provided that Landlord shall reasonably be satisfied that the facts set
      forth in any such documents or pleadings are accurate.

      8.3. Landlord has delivered to Tenant a copy of the asbestos inspection
report it has obtained with regard to the demised premises. Notwithstanding
anything contained herein to the contrary, in the event at any time during the
term of this Lease asbestos is discovered in the demised premises which is
required by applicable law to be removed or encapsulated, then, unless the same
has been introduced into the demised premises by Tenant or its agents,
contractors or employees, Landlord shall remove or encapsulate same as required
by applicable law at Landlord's sole cost and expense.

      8.4. Landlord represents that, as of the date hereof, Landlord has
received no notices of violations of any Legal Requirements affecting The
Building Project which (i) would materially and adversely affect Tenant's use of
the demised premises and (ii) have not been cured.

                                    ARTICLE 9

                    INSURANCE, LOSS, REIMBURSEMENT, LIABILITY

      9.1. Tenant shall not violate, or permit the violation of, any condition
imposed by any insurance policy then issued in respect to The Building Project
and/or the property therein and shall not do, or permit anything to be done, or
keep or permit anything to be kept in the demised premises which would subject
Landlord to any liability or responsibility for bodily injury or death or
property damage, or which would increase any insurance rate in respect to The
Building Project or the property therein over the rate

                                       24
<PAGE>

which would otherwise then be in effect or which would result in insurance
companies of good standing refusing to insure The Building Project or the
property therein in amounts reasonably satisfactory to Landlord, or which would
result in the cancellation of or the assertion of any defense by the insurer in
whole or in part to claims under any policy of insurance in respect of The
Building Project or the property therein.

      9.2. If, by reason of any failure of Tenant to comply with the provisions
of Section 8.01 or Section 9.01, the premiums on Landlord's insurance on The
Building Project and/or equipment or property therein shall be higher than they
otherwise would be for normal general and executive office use, Tenant shall
reimburse Landlord, within forty five (45) days after Landlord's demand
therefor, for that part of such premiums attributable to such failure on the
part of Tenant. A schedule or "make up" of rates for The Building Project or the
demised premises, as the case may be, issued by the applicable fire insurance
rating organization or other similar body making rates for insurance for The
Building Project or the demised premises, as the case may be, shall be
conclusive evidence of the facts therein stated and of the several items and
charges in the insurance rate then applicable to The Building Project or the
demised premises, as the case may be.

      9.3. (a) Tenant, at its expense, shall maintain at all times during the
term of this Lease (i) "all risk" property insurance covering Tenant's property
and improvements and betterments to a limit of not less than 80% of the
replacement cost thereof and (ii) comprehensive general liability insurance,
including contractual liability, in respect of the demised premises and the
conduct or operation of business therein, with Landlord and its managing agent,
if any, and any lessor of any ground or underlying lease or the holder of any
mortgage (as the case may be) whose name and address shall have been furnished
to Tenant, as additional insureds, with limits of not less than $3,000,000
combined single limit bodily injury and property damage liability. The limits of
such insurance shall not limit the liability of Tenant hereunder. Tenant shall
deliver to Landlord and any additional insureds such fully paid for policies or
certificates of insurance in form satisfactory to Landlord issued by the
insurance company or its authorized agent, at least ten (10) days before the
Commencement Date. Tenant shall procure and pay for renewals of such insurance
from time to time before the expiration thereof, and Tenant shall deliver to
Landlord and any additional insured such renewal policy at least thirty (30)
days before the expiration of any existing policy. All such policies shall be
issued by companies licensed to do business in Connecticut and rated by Best's
Insurance Reports or any successor publication of comparable standing, and
carrying a rating of A XII or better or the then equivalent of such rating.

            (b) Landlord shall maintain at all times during the term of this
      Lease, "all risk" property insurance (subject to reasonable deductible
      amounts) covering The Building Project and Landlord's property therein, in
      such amounts as may be required for the repair or restoration thereof
      without co insurance. The foregoing requirement shall not apply to the
      Landlord named herein (nor any successor landlord hereunder) so long as
      its securities are rated as "investment grade" by Moody's, Standard &
      Poor's or another national rating agency and which shall maintain one or
      more separate funds and reserves as and for insurance of its

                                       25
<PAGE>

      property generally (and including The Building Project) in reasonably
      appropriate amounts taking into account usually covered risks.

      9.4. Each party agrees to have included in each of its insurance policies
(insuring The Building Project and Landlord's property therein in the case of
Landlord, and insuring Tenant's property and improvements and betterments in the
demised premises and business interruption, in the case of Tenant, against loss,
damage or destruction by fire or other casualty) a waiver of the insurer's right
of subrogation against the other party during the term of this Lease or, if such
waiver should be unobtainable or unenforceable, (i) an express agreement that
such policy shall not be invalidated if the assured waives the right of recovery
against any party responsible for a casualty covered by the policy before the
casualty, or (ii) any other form of permission for the release of the other
party. If such waiver, agreement or permission shall not be, or shall cease to
be, obtainable from either party's then current insurance company, the insured
party shall so notify the other party promptly after learning thereof, and shall
use its best efforts to obtain the same from another insurance company described
in Section 9.03 hereof. Each party hereby releases the other party, with respect
to any claim (including a claim for negligence) which it might otherwise have
against the other party, for loss, damage or destruction with respect to its
property and, in the case of Tenant, loss of business, occurring during the term
of this Lease to the extent to which it is insured under a policy or policies
containing a waiver of subrogation or permission to release liability, as
provided in the preceding subdivisions of this section. If, notwithstanding the
recovery of insurance proceeds by either party for loss, damage or destruction
of its property, the other party is liable to the first party with respect
thereto or is obligated under this Lease to make replacement, repair or
restoration or payments then, provided the first party's right of full recovery
under its insurance policies is not thereby prejudiced or otherwise adversely
affected, the amount of the net proceeds of the first party's insurance against
such loss, damage or destruction shall be offset against the second party's
liability to the first party therefor, or shall be made available to the second
party to pay for replacement, repair or restoration, as the case may be. Nothing
contained in this section shall be deemed to relieve either party of any duty
imposed elsewhere in this Lease to repair, replace, restore or rebuild provided
for elsewhere in this Lease.

      9.5. Landlord may from time to time, but not more frequently than once
every three years, in the exercise of its reasonable judgment, require that the
amount of comprehensive general liability insurance to be maintained by Tenant
under Section 9.03 be increased, so that the amount thereof adequately protects
Landlord's interest, using industry standards for comparable office space in
Fairfield County, Connecticut.

      9.6. Landlord or its agents shall not be liable for any injury or damage
to persons or property resulting from fire, explosion, falling plaster, steam,
gas, electricity, water, rain or snow or leaks from any part of the Building, or
from the pipes, appliances or plumbing works or from the roof, street or
subsurface or from any other place or by dampness or by any other cause of
whatsoever nature, unless any of the foregoing shall be caused by or due to the
negligence of Landlord, its agents or employees.

                                       26
<PAGE>

      9.7. Landlord or its agents shall not be liable for any damage which
Tenant may sustain, if at any time any window of the demised premises is broken,
or temporarily closed, darkened or bricked up for any reason whatsoever, or
permanently closed, darkened or bricked up pursuant to a Legal Requirement (as
defined in Article 22 hereof), and Tenant shall not be entitled to any
compensation therefor or abatement of rent or to any release from any of
Tenant's obligations under this Lease, nor shall the same constitute an
eviction.

      9.8. Tenant shall reimburse Landlord for all expenses, damages or fines
incurred or suffered by Landlord, by reason of any breach, violation or non
performance by Tenant, or its agents, servants or employees, of any covenant or
provision of this Lease, or by reason of damage to persons or property caused by
moving property of or for Tenant in or out of the Building, or by the
installation or removal of furniture or other property of or for Tenant except
as provided in Section 6.05 of this Lease, or by reason of or arising out of the
carelessness, negligence or improper conduct of Tenant, or its agents, servants
or employees, in the use or occupancy of the demised premises. Subject to the
provisions of Section 8.02 hereof, where applicable, Tenant shall have the
right, at Tenant's own cost and expense, to participate in the defense of any
action or proceeding brought against Landlord, and in negotiations for
settlement thereof if, pursuant to this Section 9.08, Tenant would be obligated
to reimburse Landlord for expenses, damages or fines incurred or suffered by
Landlord.

      9.9. Tenant shall give Landlord notice in case of fire or accidents in the
demised premises promptly after Tenant is aware of such event.

      9.10. Tenant agrees to look solely to Landlord's estate and interest in
the Building, or the lease of the Building, or of The Building Project (as such
term is defined in subsection 3.02(b) hereof) and the demised premises, for the
satisfaction of any right or remedy of Tenant for the collection of a judgment
(or other judicial process) requiring the payment of money by Landlord, in the
event of any liability by Landlord, and no other property or assets of Landlord
shall be subject to levy, execution, attachment, or other enforcement procedure
for the satisfaction of Tenants remedies under or with respect to this Lease,
the relationship of Landlord and Tenant hereunder, or Tenant's use and occupancy
of the demised premises, or any other liability of Landlord to Tenant.

      10.1. If an excavation or other substructure work shall be made upon land
adjacent to the Building, or shall be authorized to be made, Tenant shall afford
to the person causing or authorized to cause such excavation, license to enter
upon the demised premises for the purpose of doing such work as shall be
necessary to preserve the wall of or the Building of which the demised premises
form a part from injury or damage and to support the same by proper foundations
without any claim for damages or indemnity against Landlord, or diminution or
abatement of rent unless due to Landlord's gross

                                       27

negligence. Landlord shall use its reasonable efforts to minimize any
inconvenience to Tenant or any interruption of Tenant's business caused by any
such entry provided, however, that in no event shall Landlord be required to
incur overtime or premium pay charges in connection therewith. The provisions of
Section 7.06 hereof shall apply to Landlord's entry hereunder.

                                   ARTICLE 11

                    ASSIGNMENT, MORTGAGING, SUBLETTING, ETC.

      11.1. (a)   Tenant shall not (1) assign or otherwise transfer this
                  Lease or the term and estate hereby granted, (2) sublet the
                  demised premises or any part thereof or allow the same to be
                  used or occupied by others or in violation of Article 5
                  hereof, (3) mortgage, pledge or encumber this Lease or the
                  demised premises or any part thereof in any manner by reason
                  of any act or omission on the part of Tenant, or (4)
                  advertise, or authorize a broker to advertise, for a subtenant
                  or an assignee, without, in each instance, obtaining the prior
                  consent of Landlord, except as otherwise expressly provided in
                  this Article 11. Landlord agrees that it will not unreasonably
                  withhold its consent to Tenant's advertisement or Tenant's
                  authorization of a broker's advertisement for a subtenant or
                  assignee provided Tenant shall have complied with the
                  provisions of Section 11.05 hereof and Landlord shall not have
                  exercised any of the rights granted therein. For purposes of
                  this Article 11, (i) the transfer of a majority of the issued
                  and outstanding capital stock of any corporate tenant, or of a
                  corporate subtenant, or the transfer of a majority of the
                  total interest in any partnership tenant or subtenant, however
                  accomplished, whether in a single transaction or in a series
                  of related or unrelated transactions, shall be deemed an
                  assignment of this Lease, or of such sublease, as the case may
                  be, except that the transfer of the outstanding capital stock
                  of any corporate tenant, or subtenant, shall be deemed not to
                  include the sale of such stock by persons or parties, through
                  the "over the counter market" or through any recognized stock
                  exchange, (ii) any agreement whereby a third party takes over
                  the obligations of Tenant under the Lease shall be deemed an
                  assignment of this Lease, (iii) any person or legal
                  representative of Tenant, to whom Tenant's interest under this
                  Lease passes by operation of law, or otherwise, shall be bound
                  by the provisions of this Article 11, and (iv) a modification,
                  amendment or extension of a sublease shall be deemed a
                  sublease.

          (b) If Tenant intends to assign this Lease or sublease the demised
     premises or any portion thereof (other than by an assignment or sublease
     contemplated by Section 11.02 hereof), Tenant shall first comply with the
     provisions of Section 11.05 hereof and Landlord shall have the rights
     described therein. If

                                       28
<PAGE>

      Landlord does not exercise any of its rights under Section 11.05 hereof
      then, provided Tenant shall have complied with the provisions of this
      Article 11, Landlord shall not unreasonably withhold or delay its consent
      to an assignment of this Lease or a sublease of the demised premises as
      more specifically set forth in Section 11.07 hereof. The provisions of
      this subsection 11.01(b) are meant to be a summary only of the provisions
      of this Article 11 and this subsection 11.01(b) in no way shall limit the
      scope of this Article 11 nor the intent or application of any provision
      hereof. In the event of any conflict between the provisions of this
      subsection 11.01(b) and the other provisions of this Article 11, such
      other provisions shall prevail.

     11.2. The provisions of Section 11.01 hereof shall not apply to
transactions with a corporation into or with which Tenant is merged or
consolidated or with an entity to which substantially all of Tenant's assets or
all or a majority of Tenant's stock are transferred (provided such merger or
transfer of stock or assets is for a good business purpose and not principally
for the purpose of transferring the leasehold estate created hereby, and
provided further, that the assignee has a net worth at least equal to or in
excess of the net worth of Tenant immediately prior to such merger or transfer,
such net worth to be calculated in accordance with generally accepted accounting
principles consistently applied) or, if Tenant is a partnership, with a
successor partnership, nor shall the provisions of clauses (l) and (2) of
Section 11.01 apply to transactions with any person, corporation, partnership,
joint venture or other entity which, directly or indirectly controls, is
controlled by or is under common control with the Tenant named herein (each
named hereinafter referred to as an "Affiliate of Tenant"). For the purposes of
the foregoing, "control" shall mean ownership of a majority of the legal and
beneficial interest in such corporation, together with the ability to direct the
management, affairs and operations thereof. Any transfer or cessation of control
over any Affiliate to which this Lease is assigned shall constitute an
assignment of this Lease to which all of the provisions of this Article 11,
other than the provisions of this Section 11.02, shall apply.

     11.3. Any assignment or transfer made hereunder, shall be made only if, and
shall not be effective until, the assignee shall execute, acknowledge and
deliver to Landlord a recordable agreement, in form and substance reasonably
satisfactory to Landlord, whereby the assignee shall assume the obligations and
performance of this Lease and agree to be personally bound by and upon all of
the covenants, agreements, terms, provisions and conditions hereof on the part
of Tenant to be performed or observed and whereby the assignee shall agree that
the provisions of this Article 11 shall, notwithstanding such an assignment or
transfer, continue to be binding upon it in the future. Tenant covenants that,
notwithstanding any assignment or transfer of this Lease, whether or not in
violation of the provisions of this Lease, and notwithstanding the acceptance of
fixed annual rent by Landlord from an assignee or transferee or any other party,
Tenant shall remain fully and primarily liable for the payment of the fixed
annual rent and additional rent due and to become due under this Lease and for
the performance of all of the covenants, agreements, terms, provisions and
conditions of this Lease on the part of Tenant to be performed or observed.

                                       29
<PAGE>

     11.4. The liability of Tenant, and the due performance by Tenant of the
obligations on its part to be performed under this Lease, shall not be
discharged, released or impaired in any respect by an agreement or stipulation
made by Landlord or any grantee or assignee of Landlord by way of mortgage, or
otherwise, extending the time of, or modifying any of the obligations contained
in this Lease, or by any waiver or failure of Landlord to enforce any of the
obligations on Tenant's part to be performed under this Lease, and Tenant shall
continue liable hereunder. If any such agreement or modification operates to
increase the obligations of a tenant under this Lease, the liability under this
Section 11.04 of the tenant named in the Lease or any of its successors in
interest, (unless such party shall have expressly consented in writing to such
agreement or modification) shall continue to be no greater than if such
agreement or modification had not been made. To charge Tenant named in this
Lease and its successors in interest, no demand or notice of any default shall
be required. Tenant and each of its successors in interest hereby expressly
waive any such demand or notice.

     11.5.  (a)   If Tenant shall have a bona fide intention to (i) assign this
                  Lease, other than by an assignment contemplated by Section
                  11.02 hereof, or (ii) sublet all or substantially all (as such
                  term is hereinafter defined) of the demised premises other
                  than by a sublease contemplated by Section 11.02 hereof, then
                  Tenant shall first give notice to Landlord of such fact and of
                  the effective date of the proposed assignment or of the
                  commencement of the term of the proposed sublease and if
                  applicable, the area of the demised premises proposed to be
                  sublet, and Landlord shall then have the right to elect, by
                  notifying Tenant within forty five (45) days of receipt of
                  such notice, to (i) terminate this Lease, as of the intended
                  effective date of such proposed assignment or the commencement
                  of the term of the proposed sublease, as the case may be, (ii)
                  accept an assignment of this Lease from Tenant to Landlord,
                  and Tenant shall then promptly execute and deliver to
                  Landlord, in form reasonably satisfactory to Landlord's
                  counsel (which shall provide in part that no merger of
                  leasehold interests shall occur), an assignment which shall be
                  effective as of the effective date of such assignment as
                  aforesaid, or (iii) accept a sublet of the demised premises in
                  accordance with the provisions of subsection 11.05(c) of this
                  Lease. For the purposes of this Article 11, a sublease of
                  substantially all of the demised premises shall be a sublease
                  which results in Tenant and Affiliates of Tenant occupying
                  less than one (l) full floor of a Wing of the Building.

          (b) If Tenant shall have a bona fide intention to sublet less than
     substantially all of the demised premises, other than by a sublease
     contemplated by Section 11.02 hereof, Tenant shall first give notice to
     Landlord of such fact and of the area it proposes to sublet and for what
     term. Such notice shall be deemed an offer by Tenant whereby Landlord may
     elect within thirty (30) days of such notice with respect to a sublease of
     less than 30,000 rentable square feet, and otherwise

                                       30
<PAGE>

      within forty-five (45) days of such notice, to (i) accept a sublease from
      Tenant with respect to the portion of the demised premises proposed to be
      sublet (hereinafter sometimes called the "Leaseback Area") for the term
      specified in Tenant's notice, or (ii) with respect to a subletting of
      Leaseback Areas for the remainder of the term or substantially all of the
      remainder of the term of this Lease, terminate the Lease with respect to
      such Leaseback Area.

            (c) If Landlord should elect to have Tenant execute and deliver a
      sublease pursuant to any of the provisions of this Section 11.05, said
      sublease shall be in a form reasonably satisfactory to Landlord's counsel
      and on all the terms contained in this Lease, except that:

                  (l) it shall permit Landlord to make further subleases of all
            or any part of the demised premises or the Leaseback Area as the
            case may be and (at no cost or expense to Tenant) to make and
            authorize any and all changes, alterations, installations and
            improvements in such space as Landlord may deem necessary for such
            subletting, at Landlord's expense provided, however, that in the
            event Landlord shall desire to alter the Leaseback Area for purposes
            other than general office purposes Landlord shall first be required
            to obtain Tenant's consent to such alterations which consent, Tenant
            agrees, (i) shall not be unreasonably withheld or delayed and (ii)
            shall be deemed given in the event Tenant does not respond to a
            request therefor within thirty (30) days after such request is made;

                  (2) it shall provide that Tenant will at all times permit
            reasonably appropriate means of ingress to and egress from the
            Leaseback Area;

                  (3) such sublease shall expressly negate any intention that
            the estate created under such sublease be merged with any other
            estate held by either of the parties;

                  (4) the sublease shall not provide for any work to be done for
            the subtenant or for any initial rent concessions or contain
            provisions inapplicable to a sublease;

                  (5) it shall provide that at the expiration of the term of
            such sublease Tenant will accept the Leaseback Area in its then
            existing condition, subject to the obligation of Landlord to make
            such repairs thereto as may be necessary to preserve the Leaseback
            Area in good order and condition, ordinary wear and tear excepted in
            accordance with Tenant's obligations to repair the demised premises
            as set forth in Article 7 hereof provided, however, that in the
            event Landlord shall have altered the Leaseback Area so that the
            same is not suitable for general office purposes Landlord shall, at
            Landlord's expense, restore the Leaseback Area to general office
            space;

                                       31
<PAGE>

                  (6) it shall provide that any consent required of Tenant, as
            lessor under that sublease, shall be deemed granted if consent with
            respect thereto is granted by Landlord except the consent required
            under clause (1) above;

                  (7) there shall be no limitation as to the use of the sublet
            premises by the subtenant thereunder except (a) as set forth in
            Article 37 and Article 5 hereof, and (b) Landlord shall not permit
            use of the sublet premises by any of "Tenant's Competitors" (as that
            term is defined in Section 11.11 hereof);

                  (8) any failure of the subtenant thereunder to comply with the
            provisions of said sublease, other than with respect to the payment
            of rent to Tenant or the willful misconduct of such subtenant which
            causes damage to Tenant, shall not constitute a default thereunder
            if Landlord has consented to such noncompliance;

                  (9) Tenant shall be released from all obligations under this
            Lease as to the Leaseback Area during the period of time it is
            sublet to Landlord, other than from Tenant's obligations to pay
            fixed annual rent and additional rent therefor and any default under
            any such sublease shall not give rise to default under a similar
            obligation contained in this Lease, nor shall Tenant be liable for
            any default under this Lease or deemed to be in default hereinunder
            if such default is occasioned by or arises from any act or omission
            of the subtenant under such sublease or is occasioned by or arises
            from any act or omission of any occupant holding under or pursuant
            to any such sublease; and

                  (10) the rental terms shall be the rental terms contained in
            this Lease on a per rentable square foot basis.

      If pursuant to the exercise of any of Landlord's options pursuant to this
      Section 11.05 this Lease is terminated as to only a portion of the demised
      premises, then the fixed annual rent payable hereunder and the additional
      rent payable pursuant to Articles 3 and 4 hereof shall be adjusted in
      proportion to the portion of the demised premises affected by such
      termination.

      11.6. (a) If Landlord shall exercise any of its options under Section
11.05 hereof and shall thereafter enter into one or more leases or underleases
with respect to all or any portion of the demised premises as to which Landlord
shall have exercised such option, Landlord shall pay to Tenant after deduction
of "Permitted Expenses" (as such term is hereinafter defined) fifty percent
(50%) of any rents, additional charges or other consideration paid under such
lease or underlease or otherwise by the tenant or undertenant, as the case may
be, during the then balance of the term of this Lease which are in excess of the
fixed annual rent or additional rent (if such excess in fact exists) payable by
Tenant hereunder (or which would be payable by Tenant hereunder if the Lease
were in

                                       32
<PAGE>

effect) commencing upon the effective date of such option and for the balance of
the term of this Lease with respect to such space Con a proportionate rentable
area basis). Amounts received by Landlord or any Affiliate of Landlord for
performing any services for any tenant or undertenant shall not be considered
consideration received by Landlord for purposes of this Section 11.06. As used
herein the term "Permitted Expenses" shall mean the aggregate of (i) usual
broker commissions and reasonable legal fees incurred by Landlord in connection
with any such lease or underlease, (ii) the costs, if any, incurred by Landlord
in separating the space from the balance of the demised premises, (iii)
reasonable advertising expenses incurred by Landlord, (iv) reasonable costs
incurred by Landlord in preparing the space for occupancy, including cash
allowances in lieu thereof, and (v) the amount of any lost rent resulting from
rent concession or abatement periods not exceeding six months. "Permitted
Expenses" shall be reduced by the aggregate of expenses in the nature of those
listed in subdivisions (i) through (v) hereof incurred by Tenant in connection
with the procurement of such tenant or undertenant.

            (b) If Landlord shall exercise any of its options under Section
      11.05 hereof, then the number of parking spaces of which Tenant shall have
      free use pursuant to Section 17.03 hereof shall be reduced as provided in
      Section 17.03 hereof.

      11.7. In the event that Landlord does not exercise any of the options
available to it pursuant to Section 11.05 hereof, Landlord shall not
unreasonably withhold or delay its consent to an assignment of this Lease or a
subletting of the whole or a part of the demised premises provided:

            (a) Tenant shall furnish Landlord with the name and business address
      of the proposed subtenant or assignee, information with respect to the
      nature and character of the proposed subtenant's or assignee's business,
      or activities, an executed counterpart of the sublease or assignment
      agreement and with respect to a proposed subletting of 30,000 or more
      rentable square feet of the demised premises (any such subletting is
      herein called a "Material Sublease") such references and current financial
      information with respect to net worth, credit and financial responsibility
      as are reasonably satisfactory to Landlord;

            (b) The nature and character of the proposed subtenant or assignee,
      its business or activities and intended use of the demised premises, is
      not in violation of Articles 5 or 37 hereof;

            (c) The proposed subtenant or assignee is not then an occupant of
      any part of the Building or a party who dealt with Landlord or Landlord's
      agent (directly or through a broker) with respect to space in the Building
      during the three (3) months immediately preceding Tenant's request for
      Landlord's consent;

            (d) All costs incurred with respect to providing reasonably
      appropriate means of ingress and egress from the sublet space or to
      separate the sublet space from the remainder of the demised premises
      shall, subject to the provisions of

                                       33
<PAGE>

      Article 6 hereof with respect to alterations, installations, additions or
      improvements be borne by Tenant;

            (e) Each sublease or assignment shall specifically state that (i) it
      is subject to all of the terms, covenants, agreements, provisions, and
      conditions of this Lease, including the waiver, agreement and permission
      requirements set forth in Section 9.04 hereof as applied to the subtenant
      or assignee, (ii) the subtenant or assignee, as the case may be, will not
      have the right to a further assignment thereof or sublease or assignment
      thereunder, or to allow the demised premises to be used by others, without
      the consent of Landlord in each instance, provided, however, Landlord
      agrees that it will not unreasonably withhold its consent or approval with
      respect to an initial assignment or subletting by (l) the permitted
      assignee of the Lease or (2) subtenant of a Material Sublease of the named
      Tenant herein, (iii) a consent by Landlord thereto shall not be deemed or
      construed to modify, amend or affect the terms and provisions of this
      Lease, or Tenant's obligations hereunder, which shall continue to apply to
      the premises involved, and the occupants thereof, as if the sublease or
      assignment had not been made.

            (f) Tenant shall together with requesting Landlord's consent
      hereunder, have paid Landlord any costs incurred by Landlord to review the
      requested consent including any reasonable attorneys fees incurred by
      Landlord;

            (g) The proposed subtenant or assignee is not an entity set forth in
      Article 37 hereof;

            (h) In the case of a subletting of a portion of the demised
      premises, the portion so sublet shall be at least 2,500 rentable square
      feet and regular in shape and such subletting will not result in more than
      four occupants (including Tenant) occupying any floor of the demised
      premises.

            (i) Tenant shall not publicly advertise the demised premises at a
      rental rate less than the rental rates then being charged under leases
      being entered into by Landlord for comparable space in the Building and
      for a comparable term.

      11.8. In the event that (a) Landlord fails to exercise any of its options
under Section 11.05 hereof and Tenant fails to execute and deliver an assignment
or sublease within 180 days after the giving of Tenant's notice of its intention
with respect thereto, then, Tenant shall again comply with all of the provisions
and conditions of Section 11.05 before assigning this lease or subletting the
demised premises, provided however if Tenant shall within thirty (30) days after
the expiration of said 180 day period agree to assign the Lease or sublease the
demised premises and shall submit the same to Landlord as described in Section
11.05 hereof, Landlord shall have twenty (20) days to make the elections set
forth in Section 11.05 with respect to such assignment or sublease.

      11.9. (a) If Landlord shall fail to respond to Tenant's request for
Landlord's consent to a proposed subletting or assignment within thirty (30)
days after Tenant's

                                       34
<PAGE>

submission thereof, then provided Tenant shall have fully complied with the
provisions of this Article 11 with respect to such assignment or subletting,
Landlord shall be deemed to have consented thereto.

            (b) If the Landlord shall give or be deemed to have given its
      consent to any assignment of this Lease or to any sublease, Tenant shall
      in consideration therefor, pay to Landlord, as additional rent:

                  (i) in the case of an assignment, an amount equal to fifty
            (50%) percent of all sums and other considerations (hereinafter
            collectively called the "Assignment Consideration") paid to Tenant
            by the assignee for or by reason of such assignment or otherwise
            (including, but not limited to, sums paid for the sale of Tenant's
            fixtures, leasehold improvements, equipment, furniture, furnishings
            or other personal property, less, in the case of a sale of Tenant's
            personal property, the higher of: (A) the then net unamortized or
            undepreciated cost thereof determined on the basis of Tenant's
            federal income tax returns or (B) the then fair market value thereof
            but excluding from the Assignment Consideration all reimbursements
            by an assignee to Tenant for amounts actually expended by Tenant in
            providing services for such assignee); and

                  (ii) in the case of a sublease, an amount equal to fifty (50%)
            percent of any rents, additional charge or other consideration
            payable under the sublease or otherwise to Tenant by the subtenant
            which is in excess (hereinafter called the "Excess Amount") of the
            fixed annual rent and additional rent accruing during the term of
            the sublease in respect of the subleased space Cat the rate per
            square foot payable by Tenant hereunder) pursuant to the terms
            hereof (including, but not limited to, sums paid for the sale or
            rental of Tenant's fixtures, leasehold improvements, equipment,
            furniture or other personal property, less, in the case of the sale
            of Tenant's personal property, the higher of: (A) the then net
            unamortized or undepreciated cost thereof determined on the basis of
            Tenant's federal income tax returns or (B) the then fair market
            value thereof).

In determining the Excess Amount and the Assignment Consideration there shall be
deducted therefrom the amount of any Permitted Expenses. As used in the next
preceding sentence the term "Permitted Expenses" shall have the same meaning as
set forth in subsection 11.06(a) hereof except that for the purposes of this
Section 11.09, Permitted Expenses shall be expenses incurred by Tenant in
connection with any subletting or assignment pursuant to this Section 11.09.

The sums payable under this Section 11.09 shall be paid to Landlord as and when
paid by the subtenant or assignee, as the case may be, to Tenant.

Tenant shall advise Landlord in the event of a sale of personal property in
connection with an assignment or subletting of the value allocated thereto and,
upon Landlord's

                                       35
<PAGE>

request, the undepreciated cost thereof determined on the basis of Tenant's
federal income tax returns. In the event that such allocated value exceeds such
undepreciated cost, Landlord may, at its election, dispute such valuation within
thirty (30) days after the submission thereof, in which event Landlord shall
name an appraiser reasonably satisfactory to Tenant (or if the parties are
unable to agree, an appraiser selected at the initiative of either party by the
American Arbitration Association) to conclusively establish the fair market
value of such property.

      11.10. If Tenant defaults in the payment of any rent, Landlord is
authorized to collect any rents due or accruing from any assignee, subtenant or
other occupant of the demised premises and to apply the net amounts collected to
the fixed annual rent and additional rent reserved herein. The receipt by
Landlord of any amounts from an assignee or subtenant, or other occupant of any
part of the demised premises shall not be deemed or construed as releasing
Tenant from Tenant's obligations hereunder or the acceptance of that party as a
direct tenant.

      11.11. For the purposes of Subsection ll.05(c)C7) hereof, the term
"Tenant's Competitors" shall mean an entity whose principal business shall be
that of a health insurer, health care provider or health maintenance
organization (which may include a division or subsidiary of Landlord) but
nothing in this Section 11.11 shall prohibit Landlord from leasing any portion
of the Building to a tenant having a division or subsidiary engaged in such
business, provided such division or subsidiary shall not occupy such portion of
the Building. Notwithstanding any language to the contrary contained in this
Section 11.11, Tenant agrees that the existing tenants of The Building Project
and any affiliates or successors thereto shall not be deemed a Tenant's
Competitor.

      11.12. Notwithstanding any language to the contrary contained in Section
11.05(c) hereof, in the event that Tenant should agree subject to the provisions
of this Lease to sublet (such sublease is hereinafter called a "Partial Term
Sublease") a portion of the demised premises for a term which is less than
substantially all of the balance of the then term of this Lease, then provided
(i) Tenant shall have entered into three or more subleases of the space
(hereinafter called the "Partial Term Sublease Space") proposed to be sublet by
the Partial Term Sublease during the six (6) year period prior to the date
Tenant shall deliver such Partial Term Sublease to Landlord pursuant to
subsection 11.05(c) hereof, and (ii) the sum of (a) the rentable area demised
under the Partial Term Sublease Space, and (b) the rentable area of the demised
premises currently being subleased by Tenant shall be 50,000 rentable square
feet or more, Landlord shall have the right to terminate the Lease with respect
to such Partial Term Sublease Space as of the proposed effective date of such
Partial Term Sublease.

      11.13. At the request of Tenant, Landlord shall enter into an agreement
with any subtenant of Tenant which has been approved by Landlord pursuant to the
provisions of Section 11.07 hereof providing that, if Landlord shall succeed to
the interest of Tenant under Tenant's sublease agreement (hereinafter called an
"Approved Sublease") with such subtenant as a result of the default of Tenant
under this Lease, Landlord shall be

                                       36
<PAGE>

bound by the provisions of such Approved Sublease and shall not terminate such
Approved Sublease so long as the subtenant shall not be in default thereunder,
provided that: (a) the fixed rent and additional rent payable under the Approved
Sublease are not less than the fixed rent and additional rent payable under this
Lease from time to time on a pro rata basis; (b) the Approved Sublease covers
not less than 50,000 rentable square feet; (c) the subleased space does not
destroy the contiguity of the balance of the demised premises; and (d) the
subtenant is a reputable party whose financial net worth, credit and financial
responsibility is, considering the rental payable under the Approved Sublease,
reasonably satisfactory to Landlord.

      11.14. In the event that this Lease shall be assigned to Landlord or
Landlord's designee or if the demised premises shall be sublet to Landlord or
Landlord's designee pursuant to Section 11.05, the provisions of any such
sublease or assignment and the obligations of Landlord and the rights of Tenant
with respect thereto shall not be binding upon or otherwise affect the rights of
any holder of a superior mortgage or of a lessor under a superior lease unless
such holder or lessor shall elect by written notice to Tenant to succeed to the
position of Landlord or its designee, as the case may be, thereunder.

                                   ARTICLE 12

                                   ELECTRICITY

      12.1. (a)   Landlord shall furnish to Tenant the electric energy which
                  Tenant requires in the demised premises on a "rent inclusion"
                  basis, through the presently installed electrical facilities
                  for Tenant's reasonable use in the demised premises of the
                  heating, ventilating and air conditioning equipment in the
                  demised premises and for lighting, light office and mechanical
                  equipment that does not require in excess of a 110 volt line.
                  Subject to the following provisions of this Section 12.01,
                  there shall be no charge to Tenant therefor by way of
                  measuring the same on any meter or otherwise, electric current
                  being included as an additional service in the fixed annual
                  rent payable hereunder.

                  (b) Tenant acknowledges and agrees (i) that the fixed annual
            rent hereinabove set forth in this Lease includes an Electricity
            Rent Inclusion Factor (as hereinafter defined), of $247,108.50 to
            compensate Landlord for the electrical wiring and other
            installations necessary for, and for its obtaining and
            redistribution of, electric current as an additional service to the
            demised premises; and (ii) that said Electricity Rent Inclusion
            Factor (hereinafter called "ERIF") has been partially based upon
            Tenant's estimated connected electrical load and hours of use
            thereof for ordinary lighting, heating, ventilating, air
            conditioning and light office equipment, during ordinary business
            hours in the demised premises. If Tenant requires a greater or
            lesser amount of electric energy than estimated, including electric
            energy to be supplied to the demised premises for heating,
            ventilating, air conditioning, lighting and light office equipment
            and equipment other than

                                       37
<PAGE>

            ordinary lighting and office equipment, then the ERIF shall not be
            adjusted, but Tenant shall pay, as additional rent, or Landlord
            shall credit Tenant the "Adjustment" (as hereinafter defined). The
            "Adjustment" shall mean the amount remaining (whether a positive or
            negative number) after subtracting the ERIF from the amount
            determined by applying the connected electrical load and usage and
            demand (hereinafter called "Tenant's Actual Electrical Usage")
            thereof in the demised premises (as determined by the electrical
            consultant as hereinafter provided) to the rate charged for such
            load and usage in the service classification in effect on the date
            of this Lease pursuant to which Landlord then purchased electric
            current for the entire Building from the public utility corporation.
            If the cost to Landlord of electricity shall have been, or shall be,
            increased or decreased subsequent to the date of this Lease (whether
            such increase or decrease occurs prior to or during the term of this
            Lease), by change in Landlord's electric rates, charges, fuel
            adjustment, or service classifications, or by taxes or charges of
            any kind imposed thereon, or for any other such reason, then the
            same shall be taken into account in computing the Adjustment. The
            Adjustment shall be calculated monthly, in arrears, by Landlord's
            consultant as provided in paragraph (d) hereof.

                  (c) Any such increase or decrease in Landlord's cost due to
            change in Landlord's electric rates, charges, etc., shall be
            computed by the application of the average consumption (energy and
            demand) of electricity for the entire Building for the twelve (12)
            months immediately prior to the rate change, other change in cost,
            or any changed methods of or rules on billing for same, on a
            consistent basis to the new rate and/or service classifications and
            to the immediately prior existing rate and/or service
            classifications. The parties acknowledge that they understand that
            it is anticipated that existing electric rates, charges, etc. may be
            changed by virtue of time of day rates or other methods of billing,
            and that the foregoing reference to changes in methods of or rules
            on billing is intended to include any such change. The parties agree
            that a reputable, independent electrical consultant, selected by
            Landlord ("Landlord's electrical consultant") shall determine the
            Adjustment based on changes in Landlord's electric rates, charges,
            etc.

                  (d) Tenant's Actual Electrical Usage shall be calculated on a
            monthly basis by Landlord's electrical consultant using the check
            meters located in the demised premises and making such adjustments
            to the measurements thereof as may be deemed necessary by such
            consultant. If any meters or other equipment must be installed to
            check electric service to the demised premises, the same shall be
            installed by Landlord at Landlord's expense, not to exceed in the
            aggregate $20,000.00, and Tenant shall reimburse Landlord for the
            cost thereof in excess of $20,000.00 in such equal monthly amounts
            commencing after Landlord's completion of the installation thereof
            as shall amortize such cost over the number of full months then
            remaining in the term of this Lease without regard to any
            unexercised rights of renewal or extension hereunder, and such
            monthly amounts shall be paid by Tenant to Landlord as additional
            rent hereunder.

                                       38
<PAGE>

                  (e) The determination of Landlord's consultant shall be
            binding and conclusive on Landlord and on Tenant from and after the
            delivery of copies of such determination to Landlord and Tenant,
            unless within ninety (90) days after the delivery of such copies,
            Tenant disputes such determination. If Tenant disputes the
            determination, it shall, at its own expense, obtain from a
            reputable, independent electrical consultant its own survey of
            Tenant's Actual Electrical Usage in the demised premises in
            accordance with the provisions of this Article 12. Tenant's
            consultant and Landlord's consultant then shall seek to agree on a
            finding of such determination of Tenant's Actual Electrical Usage.
            If they cannot agree, they shall choose a third reputable electrical
            consultant whose cost shall be shared equally by Landlord and
            Tenant, to make a similar survey, and the determination of such
            third electrical consultant shall be controlling. (If they cannot
            agree on such third consultant, within ten (10) days, then either
            party may apply to the Superior Court Judicial District of Stamford!
            Norwalk at Norwalk Housing Session, State of Connecticut for the
            appointment of such third consultant.) However, pending such
            determination, Tenant shall pay to Landlord the amount of the ERIF
            and the Adjustment as determined by Landlord's electrical
            consultant, then Landlord and Tenant shall make adjustment for any
            deficiency owed by Tenant or overage paid by Tenant pursuant to the
            decision of Landlord's electrical consultant together with interest
            on such adjustment at the Interest Rate from the date owed, in the
            case of a deficiency, or from the date paid, in the case of an
            overage.

      12.2. Landlord reserves the right to discontinue furnishing electric
energy to Tenant at any time upon one hundred eighty (180) days' written notice
to Tenant provided Landlord shall have previously or contemporaneously therewith
discontinued furnishing electricity to at least seventy-five (75%) percent of
the rentable area in the Building (including the demised premises). From and
after the effective date of such termination, Landlord shall no longer be
obligated to furnish Tenant with electric energy, provided, however, that such
termination date shall be extended for a time reasonably necessary for Tenant to
make arrangements to obtain electric service directly from the public utility
company servicing the Building. If Landlord exercises such right of termination,
this Lease shall remain unaffected thereby and shall continue in full force and
effect; and thereafter Tenant shall diligently arrange to obtain electric
service directly from the public utility company servicing the Building, and may
utilize the then existing electric feeders, risers and wiring serving the
demised premises to the extent available and safely capable of being used for
such purpose and only to the extent of Tenant's then authorized connected load.
Landlord shall be obligated to pay the reasonable cost required for Tenant to
obtain direct electric service unless Landlord discontinued furnishing
electricity to Tenant by reason of Legal Requirements or the rules and
regulations of the public utility furnishing electricity to the Building, in
which case Landlord and Tenant shall share equally such costs. Commencing with
the date when Tenant receives such direct service, and as long as Tenant shall
continue to receive such service, the ERIF amount and Adjustments shall not be
payable and Tenant shall obtain electric service direct from the utility
furnishing such power to the Building and shall pay all charges therefor to such
utility.

                                       39
<PAGE>

      12.3. Tenant agrees not to connect any additional electrical equipment of
any type to the Building electric distribution system, other than lamps,
typewriters and other small office machines which consume comparable amounts of
electricity, without Landlord's prior written consent, which consent shall not
be unreasonably withheld. To facilitate Tenant's increasing automation of its
operations, any additional risers, feeders, or other equipment proper or
necessary to supply Tenant's electrical requirements may be installed by Tenant,
at the sole cost and expense of Tenant and in accordance with the provisions of
Article 6 hereof, if, the same are necessary and will not cause permanent damage
or injury to the Building or the demised premises, or cause or create a
dangerous or hazardous condition or entail excessive or unreasonable
alterations, repair or expense or unreasonably interfere with or disturb other
tenants or occupants and provided same does not adversely affect Landlord's
reasonable estimates of the electrical capacity required for the needs of
existing and future tenants of the Building and for the proper maintenance and
operation of the Building. In applying the provisions of Article 6 to any work
permitted hereunder, any consent required under Article 6 to be obtained from
Landlord shall not be unreasonably withheld or delayed. Landlord shall not in
anywise be liable or responsible to Tenant for any loss or damage or expense
which Tenant may sustain or incur if either the quantity or character of
electric service is changed or is no longer available or suitable for Tenant's
requirements. Nothing contained in the preceding sentence shall be deemed to
exculpate Landlord its agents, servants or designees from liability for its
negligent or wilfull acts.

                                   ARTICLE 13

                          DAMAGE BY FIRE OR OTHER CAUSE

      13.1. If the Building or the demised premises shall be partially or
totally damaged or destroyed by fire or other cause, then whether or not the
damage or destruction shall have resulted from the fault or neglect of Tenant,
or its employees, agents or visitors (and if this Lease shall not have been
terminated as in this Article 13 hereinafter provided), Landlord shall repair
the damage and restore and rebuild the Building and/or the demised premises, at
its expense (without limiting the rights of Landlord under any other provisions
of this Lease), with reasonable dispatch after notice to it of the damage or
destruction; provided, however, that Landlord shall not be required to repair or
replace any of Tenant's property.

      13.2. If the Building or the demised premises shall be partially damaged
or partially destroyed by fire or other cause, the fixed annual rent and
additional rent payable hereunder shall be abated to the extent that the demised
premises shall have been rendered untenantable for the period from the date of
such damage or destruction to the date the damage shall be repaired or restored.
If fifty (50%) percent or more of the area of the demised premises shall be
totally (which shall be deemed to include substantially totally) damaged or
destroyed or rendered completely (which shall be deemed to include substantially
completely) untenantable on account of fire or other cause, the fixed annual

                                       40
<PAGE>

rent and additional rent shall abate as of the date of the damage or destruction
and until Landlord shall repair, restore and rebuild the Building and the
demised premises, provided, however, that should Tenant reoccupy a portion of
the demised premises during the period the restoration work is taking place and
prior to the date that the same are made completely tenantable, rents allocable
to such portion shall be payable by Tenant from the date of such occupancy.

      13.3. (a)   If the Building shall be totally damaged or destroyed by fire
                  or other cause, or if the Building shall be so damaged or
                  destroyed by fire or other cause (whether or not the demised
                  premises are damaged or destroyed) as to require a reasonably
                  estimated expenditure of more than forty (40%) percent of the
                  full insurable value of the Building immediately prior to the
                  casualty, then, in either such case, Landlord may terminate
                  this Lease by giving Tenant notice to such effect within sixty
                  (60) days after the date of the casualty. In case of any
                  damage or destruction mentioned in this Article 13 and
                  Landlord shall decide to restore the Building, Landlord shall
                  give Tenant a notice of Landlord's estimate of the reasonable
                  expected date of restoration (as evidenced by a certificate of
                  Landlord's architect) within sixty (60) days after the date of
                  the casualty. If such estimated restoration date shall be
                  later than 18 months after the date of such damage or
                  destruction, then Tenant may terminate this Lease by giving
                  Landlord notice to such effect within ten (10) days after the
                  date of Landlord's notice. Thereafter, Tenant may terminate
                  this Lease upon ten (10) days notice to Landlord, if Landlord
                  has not substantially completed the making of the required
                  repairs and restored and rebuilt the Building within
                  Landlord's estimated restoration period or within such period
                  thereafter (not to exceed one (l) month) as shall equal the
                  aggregate period Landlord may have been delayed in doing so by
                  adjustment of insurance, labor trouble, governmental controls,
                  act of god, or any other cause beyond Landlord's reasonable
                  control.

            (b) If any damage or destruction described in this Section 13.03
      shall occur at any time during the last two (2) years of the term of this
      Lease, Tenant may terminate this Lease by notice given to Landlord within
      twenty (20) days after the date of such casualty, if the demised premises
      cannot reasonably (as evidenced by a certificate from Landlord's
      architect) be restored within three (3) months from the date of such
      damage or destruction or if Landlord has not substantially completed the
      making of the required repairs and restored and rebuilt the Building and
      the demised premises within three (3) months from the date of such damage
      or destruction.

            (c) In the event of any damage by fire or other casualty to the
      Building or the demised premises which results in a termination of this
      Lease by Landlord, Tenant shall be permitted to remain in occupancy after
      the casualty of any portion

                                       41
<PAGE>

      of the demised premises which shall not have been rendered untenantable by
      such casualty for a period following the casualty not to exceed six (6)
      months upon all the terms and conditions of this Lease, provided such
      continued occupancy shall not (i) be prohibited by Legal Requirements,
      (ii) in Landlord's reasonable judgment be hazardous or create a hazardous
      condition, (iii) interfere with Landlord's restoration of the Building or
      the demised premises, or (iv) prevent Landlord from demolishing the
      Building or any portion thereof pursuant to a Legal Requirement, and if
      Tenant shall so continue in occupancy, Tenant shall remain responsible for
      a pro rata portion of the fixed annual rent and additional rent payable by
      Tenant hereunder, based upon the portion of the demised premises occupied
      by Tenant during such period.

            (d) In the event Landlord shall restore the demised premises or the
      Building as described in this Section 13.03, Tenant's obligations to pay
      fixed annual rent and additional rent hereunder shall resume upon the
      earlier to occur of (i) the date Tenant shall occupy the demised premises
      for the conduct of its business or (ii) the later of (x) the date provided
      by Landlord in its notice as the expected date of restoration or (y) such
      date as the repair and restoration of the demised premises shall have been
      substantially completed.

            (e) The repair and restoration provided in this Section 13.03 shall
      be deemed substantially complete (i) notwithstanding the fact that minor
      or insubstantial details of construction, mechanical adjustment, or
      decoration remain to be performed, the non completion of which do not
      materially interfere with Tenant's use of the demised premises and (ii) if
      such repair and restoration has been substantially completed except for
      portions thereof which under good construction scheduling practice should
      be done after still incompleted Tenant's finish work.

            (f) If the occurrence of the conditions set forth in subsection (e)
      hereof and thereby the substantial completion of the repair and
      restoration shall be delayed due to any act or omission of Tenant or any
      of its employees, agents or contractors or any failure to plan or to
      execute Tenant's finish work diligently and expeditiously, the repair and
      restoration shall be deemed substantially complete on the date when they
      would have been substantially complete but for such delay.

      13.4. No damages, compensation or claim shall be payable by Landlord for
inconvenience, loss of business or annoyance arising from any repair or
restoration of any portion of the demised premises or of the Building pursuant
to this Article 13.

      13.5. Notwithstanding any of the foregoing provisions of this Article 13,
if Landlord or the lessor of any superior lease or the holder of any superior
mortgage shall be unable to collect all of the insurance proceeds (including
rent insurance proceeds) applicable to damage or destruction of the demised
premises or the Building by fire or other cause, by reason of Tenant's failure
or refusal to cooperate with Landlord in making a claim for such proceeds, then,
without prejudice to any other remedies which may be

                                       42
<PAGE>

available against Tenant, there shall be no abatement of Tenant's rents, but the
total amount of such rents not abated (which would otherwise have been abated)
shall not exceed the amount of uncollected insurance proceeds.

      13.6. Landlord will not carry separate insurance of any kind on Tenant's
property, and, except as provided by law or by reason of its breach of any of
its obligations hereunder, shall not be obligated to repair any damage thereto
or replace the same. Tenant shall maintain insurance on Tenant's property, and
Landlord shall not be obligated to repair any damage thereto or replace the
same.

      13.7. The provisions of this Article 13 shall be considered an express
agreement governing any cause of damage or destruction of the demised premises
by fire or other casualty, and, to the extent permitted under applicable law, no
statute, rule, law or regulation of the State of Connecticut or any of its
political subdivisions now or hereafter in force and providing for such a
contingency in the absence of an express agreement, shall have application in
such case.

                                   ARTICLE 14

                                  CONDEMNATION

      14.1. In the event that the whole of the demised premises shall be
lawfully condemned or taken in any manner for any public or quasi public use,
this Lease and the term and estate hereby granted shall forthwith cease and
terminate as of the date of vesting of title. In the event that only a part of
the demised premises shall be so condemned or taken, then, effective as of the
date of vesting of title, the fixed annual rent under Article 1 hereunder and
additional rents under Articles 3 and 4 hereunder shall be abated in an amount
thereof apportioned according to the area of the demised premises so condemned
or taken. In the event that only a part of The Building Project (as such term is
defined in subsection 3.02(b) hereof) shall be so condemned or taken, then (a)
Landlord (whether or not the demised premises be affected) may, at Landlord's
option, terminate this Lease and the term and estate hereby granted as of the
date of such vesting of title by notifying Tenant in writing of such termination
within 60 days following the date on which Landlord shall have received notice
of vesting of title, or (b) if such condemnation or taking shall be of a
substantial part (i.e., forty (40%) or more of (i) the rentable area of the
demised premises or (ii) the aggregate number of parking spaces available for
Tenant's use, provided Landlord shall be permitted to make substitutions
thereof) of the demised premises or of a substantial part of the means of access
thereto, Tenant may, at Tenant's option, by delivery of notice in writing to
Landlord within 60 days following the date on which Tenant shall have received
notice of vesting of title, terminate this Lease and the term and estate hereby
granted as of the date of vesting of title, or (c) if neither Landlord nor
Tenant elects to terminate this Lease, as aforesaid, this Lease shall be and
remain unaffected by such condemnation or taking, except that the fixed annual
rent payable under Article 1 and additional rents payable under Articles 3 and 4
shall be abated to the extent hereinbefore provided in this Section 14.01.

                                       43
<PAGE>

      14.2. In the event of its termination in any of the cases hereinbefore
provided, this Lease and the term and estate hereby granted shall expire as of
the date of such termination with the same effect as if that were the Expiration
Date, and the fixed annual rent and additional rents payable hereunder shall be
apportioned as of such date.

      14.3. In the event of any condemnation or taking hereinbefore mentioned of
all or a part of the Building, Landlord shall be entitled to receive the entire
award in the condemnation proceeding, including any award made for the value of
the estate vested by this Lease in Tenant, and Tenant hereby expressly assigns
to Landlord any and all right, title and interest of Tenant now or hereafter
arising in or to any such award or any part thereof, and Tenant shall be
entitled to receive no part of such award, except Tenant shall be entitled to
make a separate claim with the condemning authority for the value of any
Tenant's property so taken and for Tenant's moving expenses.

      14.4. It is expressly understood and agreed that the provisions of this
Article 14 shall not be applicable to any condemnation or taking for
governmental occupancy for a limited period.

      14.5. In the event of any taking of less than the whole of the Building or
the demised premises which does not result in a termination of this Lease, or in
the event of a taking for a temporary use or occupancy of all or any part of the
demised premises which does not result in a termination of this Lease, Landlord,
at its expense, and whether or not any award or awards shall be sufficient for
the purpose, shall proceed with reasonable diligence to repair, alter and
restore the remaining parts of the Building and the demised premises to
substantially their former condition to the extent that the same may be feasible
and so as to constitute a complete and tenantable Building and demised premises.

      14.6. In the event any part of the demised premises be taken to effect
compliance with any law or requirement of public authority other than in the
manner hereinabove provided in this Article 14, then, (i) if such compliance is
the obligation of Tenant under this Lease, Tenant shall not be entitled to any
diminution or abatement of rent or other compensation from Landlord therefor,
but (ii) if such compliance is the obligation of Landlord under this Lease, the
fixed annual rent hereunder shall be reduced and additional rents under Articles
3 and 4 shall be adjusted in the same manner as is provided in Section 14.01
according to the reduction in rentable area of the demised premises resulting
from such taking.

                                   ARTICLE 15

                       ACCESS TO DEMISED PREMISES; CHANGES

      15.1. Tenant shall permit Landlord to erect, use and maintain pipes, ducts
and conduits in and through the demised premises, provided the same are
installed adjacent to or concealed behind walls and ceilings of the demised
premises. Landlord shall to the

                                       44
<PAGE>

extent practicable install such pipes, ducts and conduits by such methods and at
such locations as will not materially interfere with or impair Tenant's layout
or use of the demised premises. Landlord or its agents or designees shall have
the right to enter the demised premises, at reasonable times during business
hours and except in case of emergency, upon reasonable notice (which need not be
in writing), for the making of such repairs or alterations as Landlord may deem
necessary for the Building or which Landlord shall be required to or shall have
the right to make by the provisions of this Lease or any other lease in the
Building and, subject to the foregoing, shall also have the right to enter the
demised premises for the purpose of inspecting them or exhibiting them to
prospective purchasers or lessees of the entire Building or to prospective
mortgagees of the fee or of the Landlord's interest in the property of which the
demised premises are a part or to prospective assignees of any such mortgages or
to the holder of any mortgage on the Landlord's interest in the property, its
agents or designees. Landlord shall be allowed to take all material into and
upon the demised premises that may be required for the repairs or alterations
above mentioned as the same is required for such purpose, without the same
constituting an eviction of Tenant in whole or in part, and the rent reserved
shall in no wise abate while said repairs or alterations are being made by
reason of loss or interruption of the business of Tenant because of the
prosecution of any such work. Nothing contained in this Section 15.01 shall
exculpate Landlord for the negligence of Landlord, its agents, servants or
others for whom as a matter of law it is liable. 'The reservation contained in
the preceding sentence shall, however, be subject to the provisions of Section
9.04 hereof. Landlord shall exercise reasonable diligence (including
consultation with Tenant) so as to minimize the disturbance but nothing
contained herein shall be deemed to require Landlord to perform the same on an
overtime or premium pay basis. The provisions of Section 7.06 hereof shall apply
to any entry by Landlord hereunder.

      15.2. Landlord reserves the right, without the same constituting an
eviction and without incurring liability to Tenant therefor, to change the
arrangement and/or location of public entrances, passageways, doors, doorways,
corridors, elevators, stairways, toilets and other public parts of the Building;
provided, however, that access to the Building shall not be cut off and that
there shall be no unreasonable obstruction of access to the demised premises or
unreasonable interference with the use or enjoyment thereof.

      15.3. Landlord may, during the twelve (12) months prior to expiration of
the term of this Lease, exhibit the demised premises to prospective tenants.

      15.4. If Tenant shall not be personally present to open and permit an
entry into the demised premises at any time when for any reason an entry therein
shall be urgently necessary by reason of fire or other emergency, Landlord or
Landlord's agents may forcibly enter the same without rendering Landlord or such
agents liable therefor (if during such entry Landlord or Landlord's agents shall
accord reasonable care to Tenant's property including, except in the case of
emergency, the use of any keys to the demised premises that shall have
previously been furnished to Landlord) and without in any manner affecting the
obligations and covenants of this Lease.

                                     DEFAULT

      16.1. If Tenant shall make an assignment of the property of Tenant for the
benefit of creditors, or shall file a voluntary petition under any bankruptcy or
insolvency law or any involuntary petition alleging an act of bankruptcy or
insolvency shall be filed against Tenant under any bankruptcy or insolvency law,
or whenever a petition shall be filed by or against Tenant under the
reorganization provisions of the United States Bankruptcy Act or under the
provisions of any law of like import, or whenever a petition shall be filed by
Tenant under the arrangement provisions of the United States Bankruptcy Act or
under the provisions of any law of like import, or whenever a permanent receiver
of Tenant or for the property of Tenant shall be appointed, then, Landlord may,
(a) at any time after receipt of notice of the occurrence of any such event, or
(b) if such event occurs without the acquiescence of Tenant, at any time after
the event continues for ninety (90) days, give Tenant a notice of intention to
end the term of this Lease at the expiration of five (5) days from the date of
service of such notice of intention, and upon the expiration of said five (5)
day period this Lease and the term and estate hereby granted, whether or not the
term shall theretofore have commenced, shall terminate with the same effect as
if that day were the Expiration Date, but Tenant shall remain liable for damages
provided in Section 16.03 hereof.

      16.2. If:

            (a) Tenant shall default in the payment of any installment of fixed
      annual rent, or in the payment of any additional rent or any other charge
      payable by Tenant to Landlord, on any day upon which the same ought to be
      paid, and such default shall continue for fifteen (15) days after Landlord
      shall have given Tenant a notice specifying such default; or

            (b) Tenant shall do or permit anything to be done, whether by action
      or inaction, contrary to any of Tenant's obligations hereunder, and if
      such situation shall continue and shall not be remedied by Tenant within
      twenty (20) days after Landlord shall have given to Tenant a notice
      specifying the same, or, in the case of a happening or default which
      cannot with due diligence be cured within a period of twenty (20) days and
      the continuance of which for the period required for cure will not subject
      Landlord to the risk of criminal liability as more particularly described
      in Article 8 hereof) or termination of any superior lease or foreclosure
      of any superior mortgage, if Tenant shall not, (i) within said twenty (20)
      day period advise Landlord of Tenant's intention to duly institute all
      steps necessary to remedy such situation, (ii) duly institute within said
      twenty (20) day period, and thereafter diligently prosecute to completion
      all steps necessary to remedy the same and (iii) complete such remedy
      within such time after the date of the giving of said notice of Landlord
      as shall reasonably be necessary; or

                                       46
<PAGE>

            (c) any event shall occur or any contingency shall arise whereby
      this Lease or the estate hereby granted or the unexpired balance of the
      term hereof would, by operation of law or otherwise, devolve upon or pass
      to any person, firm or corporation other than Tenant, except as expressly
      permitted by Article 11 hereof; or

            (d) Tenant shall abandon the demised premises (unless as a result of
      a casualty); or

            (e) in case any other lease held by Tenant from Landlord in the
      Building shall expire and terminate (whether or not the term thereof shall
      then have commenced) as a result of the default of Tenant thereunder or of
      the occurrence of an event as therein provided (other than by expiration
      of the fixed term thereof or pursuant to a cancellation or termination
      option therein contained); or

            (f) Tenant shall default in the due keeping, observing or
      performance of any covenant, agreement, provision or condition of Article
      5 hereof on the part of Tenant to be kept, observed or performed and if
      such default shall continue and shall not be remedied by Tenant within
      four (4) days after Landlord shall have given to Tenant a notice
      specifying the same, then in any of said cases set forth in the foregoing
      subsections 16.02 (a), (b), (c), (d), (e) and (f) hereof Landlord may (in
      addition to any and all rights at law or in equity) re enter and remove
      all persons and property from the demised premises and such property may
      be removed and stored in a public warehouse or elsewhere at the cost of,
      and for the account of Tenant, all without service of notice or resort to
      legal process and without being deemed guilty of trespass, or becoming
      liable for any loss or damage which may be occasioned thereby.

      16.3. Should Landlord elect to re enter, as herein provided, or should it
take possession pursuant to legal proceedings or pursuant to any notice provided
for by law, Landlord may either terminate this Lease, make such alterations and
repairs as may be necessary in order to relet the demised premises, and relet
the demised premises or any part thereof for such term or terms (which may be
for a term extending beyond the term of this Lease) and at such rental or
rentals and upon such other terms and conditions as Landlord in its discretion
may deem advisable; upon each such reletting all rentals received by Landlord
from such reletting shall be applied first, to the payment of any indebtedness
other than rent due hereunder from Tenant to Landlord; second, to the payment of
any costs and expenses of such reletting, including brokerage fees and
attorneys' fees and of costs of such alterations and repairs; third, to the
payment of rent due and unpaid hereunder, and the residue, if any, shall be held
by Landlord and applied in payment of future rent as the same may become due and
payable hereunder and if such residue shall exceed such future rental, Landlord
may retain such excess for its own account and Tenant shall have no interest
therein. If such rentals received from such reletting during any month be less
than that to be paid during that month by Tenant hereunder, Tenant shall pay any
deficiency to Landlord. Such deficiency shall be calculated and paid monthly. No
such re entry or taking possession of the demised

                                       47
<PAGE>

premises by Landlord shall be construed as an election on its part to terminate
this Lease unless a written notice of such intention be given to Tenant or
unless the termination thereof be decreed by a court of competent jurisdiction.
Notwithstanding any such reletting without termination, Landlord may at any time
thereafter elect to terminate this Lease for such previous breach. Should
Landlord at any time terminate this Lease for any breach, in addition to any
other remedies it may have, it may recover from Tenant all damages it may incur,
by reason of such breach, including the cost of recovering the demised premises,
reasonable attorneys' fees, and including the worth at the time of such
termination of the excess, if any, of the amount of rent and charges equivalent
to rent reserved in this Lease for the remainder of the stated term over the
then reasonable rental value of the demised premises for the remainder of the
stated term, all of which amounts shall be immediately due and payable from
Tenant to Landlord. In determining the rent which would be payable by Tenant
hereunder, subsequent to default, the annual rent for each year of the unexpired
term shall be equal to the average fixed annual rent and additional rent paid by
Tenant from the Commencement Date to the time of default.

      16.4. In case Landlord shall retain an attorney to enforce the provisions
of this Lease or if suit shall be brought for recovery of possession of the
demised premises, for the recovery of rent or any other amount due under the
provisions of this Lease, or because of the breach of any other covenant herein
contained on the part of Tenant to be kept or performed, Tenant shall pay to
Landlord all expenses incurred by Landlord in connection therewith, including a
reasonable attorneys' fee.

      16.5. (a)   In the event of a breach or threatened breach by Tenant of
                  any of its obligations under this Lease, Landlord shall also
                  have the right of injunction. The special remedies to which
                  Landlord may resort hereunder are cumulative and are not
                  intended to be exclusive of any other remedies or means of
                  redress to which Landlord may lawfully be entitled at any
                  time, and, except as provided in Article 30 hereof, Landlord
                  may invoke any remedy allowed at law or in equity as if
                  specific remedies were not provided for herein.

            (b) In the event of a breach or threatened breach by Landlord of any
      of its obligations under this Lease, Tenant shall also have the right of
      injunction. Any remedies to which Tenant may resort hereunder are
      cumulative and are not intended to be exclusive of any other remedies or
      means of redress to which Tenant may lawfully be entitled at any time,
      and, except as provided in Article 30 hereof, Tenant may invoke any remedy
      allowed at law or in equity as if specific remedies were not provided for
      herein.

      16.6. If this Lease shall terminate under the provisions of this Article
16, or if Landlord shall re enter the demised premises under the provisions of
this Article 16, or in the event of the termination of this Lease, or of re
entry, by or under any summary process or other proceeding or action or any
provision of law by reason of default hereunder on the part of Tenant, Landlord
shall be entitled to retain all moneys, if any, paid by Tenant to Landlord,
whether as advance rent, security or otherwise, but such

                                       48
<PAGE>

moneys shall be credited by Landlord against any fixed annual rent or additional
rent due from Tenant at the time of such termination or re entry or, at
Landlord's option, against any damages payable by Tenant under this Article 16
or pursuant to law.

                                   ARTICLE 17

                            COMMON AREAS AND PARKING

      17.1. Landlord shall provide and shall make available from time to time
within the boundaries of the Land such parking facilities, driveways, entrances
and exits thereto, landscape and planted areas, and other improvements and
facilities, as Landlord shall at any time and from time to time deem appropriate
(all the foregoing being collectively referred to in this Lease as "Common
Areas"). Tenant and its officers, employees, agents, customers and invitees
shall have a nonexclusive right, in common with Landlord and all others to whom
Landlord has granted or may hereafter grant rights, to use the Common Areas. The
Common Areas shall at all times be subject to the exclusive control and
management of Landlord, and Landlord shall have the right from time to time to
establish, modify and enforce reasonable rules and regulations with respect to
the Common Areas, and Tenant agrees, after notice thereof, to abide by such
rules and regulations and to cause its officers, employees, agents, customers
and invitees to conform thereto. Landlord shall construct, operate, manage,
equip, repair, landscape, and maintain the Common Areas for their intended
purposes in such manner as Landlord shall, in Landlord's sole discretion, from
time to time determine. Landlord's rights respecting the Common Areas shall
include (but shall not be limited to) the following:

                  (i) to construct, maintain and operate lighting facilities
            serving the Common Areas;

                  (ii) from time to time to change the area, level, location and
            arrangement of parking areas and other Common Area facilities, to
            make installations therein and to move or remove such installations,
            and to change the location of, or permanently diminish or
            discontinue the use of, any portion of the Common Areas;

                  (iii) to restrict parking by tenants, their officers, agents,
            employees, customers and invitees, to designated areas;

                  (iv) to discontinue, or restrict the use of, any portion of
            the Common Areas to such extent, and for such period of time, as may
            in the opinion of Landlord's counsel be necessary to prevent a
            dedication thereof or the accrual of any rights to any person or the
            public therein;

                  (v) to temporarily suspend the use of all, or any portion of,
            the Common Areas; and

                                       49
<PAGE>

                  (vi) to take any other action with respect to the Common
            Areas, as Landlord, in his sole discretion, shall determine to be
            advisable.

      17.2. Tenant's right to use the Common Areas shall be deemed to be a
license conterminous with this Lease, and Landlord shall not be subject to any
liability nor shall Tenant be entitled to any compensation or diminution or
abatement of rent by reason of Landlord's exercise of any right or rights
respecting Common Areas reserved pursuant to Section 17.01 hereof, nor shall the
exercise of any such right be deemed a constructive or actual eviction.

      17.3. Tenant shall be entitled to free use of(591 parking spaces during
the term of this Lease provided that of such parking spaces shall be located
within the covered parking garage within the Common Areas. Notwithstanding the
foregoing, in the event Tenant shall give a notice to Landlord that Tenant
requires the free use of additional parking spaces, not to exceed 48 parking
spaces, Landlord shall make such spaces available within a reasonable period;
such additional parking spaces may be located within or outside of the Common
Areas. In the event that any of the foregoing parking spaces shall be designated
by Landlord, Tenant agrees that it or its employees and invitees shall only use
such designated parking spaces. Nothing contained in Section 17.01 hereof shall
be deemed to permit Landlord to reduce, except on a temporary basis, the number
of parking spaces to be made available to Tenant pursuant to this Section 17.03.
If at any time during the term of this Lease the rentable area of the demised
premises shall be reduced, the number of spaces allocated to Tenant pursuant to
this Section 17.03 shall be reduced in proportion to such reduction in rentable
area. Such reduction shall be made as follows: (A) to the extent that the number
of Tenant's parking spaces exceed the product of (i) the quotient of (x) the
rentable area of the demised premises (as reduced) divided by (y) 1,000,
multiplied by (ii) 3, such reduction shall begin with the parking spaces that
are located inside the Common Areas (but only to the extent required so that the
number of Tenant's parking spaces inside the Common Areas shall equal such
product); (B) any further reductions shall be made to Tenant's parking spaces
which are located outside the Common Areas (until, if necessary, all of Tenant's
parking spaces outside of the Common Areas shall have been eliminated); and (C)
the balance of any reduction shall be made to those parking spaces located
inside the Common Areas.

      17.4. With respect to the parking of vehicles at The Building Project
(whether inside or outside the Common Areas):

            (a) If Landlord elects to designate a specific parking area for
      Tenant's use, Tenant shall require its personnel and visitors to park
      their vehicles only in parking spaces designated by Landlord for Tenant's
      use for its personnel and in parking spaces designated by Landlord for
      visitors, respectively, on a "first come, first served" basis. Landlord
      reserves the right at all times to redesignate such parking spaces.
      Tenant, its personnel and visitors shall not at any time park any trucks
      or delivery vehicles in any of the parking areas. Tenant shall be
      permitted to post signage (the design and installation of which shall be
      subject to Landlord's

                                       50
<PAGE>

      consent, not to be unreasonably withheld) designating fifteen (15) of the
      parking spaces allocated to Tenant for the sole use of Tenant' s officers.

            (b) All parking spaces and any other parking areas used by Tenant,
      its personnel and visitors will be at their own risk, and Landlord shall
      not be liable for any injury to person or property, or for loss or damage
      to any automobile or its contents, resulting from theft, collision,
      vandalism or any other cause whatsoever other than Landlord's willful
      misconduct or negligence (subject to the provisions of Section 9.04
      hereof).

            (c) There shall be no overnight parking, and Tenant shall, and shall
      cause its personnel and visitors to, remove their automobiles from the
      parking area at the end of the working day. If any automobile owned by
      Tenant or by its personnel or visitors remains in the parking area
      overnight and the same interferes with the cleaning or maintenance of said
      area (snow or otherwise), any costs or liabilities incurred by Landlord in
      removing said automobile to effectuate cleaning or maintenance, or any

      25.7. Tenant agrees that it will pay no rent under this Lease more than
thirty (30) days in advance of its due date, if so restricted by any existing or
future ground lease or mortgage to which this Lease is subordinated or by an
assignment of this Lease to the ground lessor or the holder of such mortgage,
and, in the event of any act or omission by Landlord, Tenant will not exercise
any right to terminate this Lease or to remedy the default and deduct the cost
thereof from rent due hereunder until Tenant shall have given written notice of
such act or omission to the ground lessor and to the holder of any mortgage on
the fee or the ground lease who shall have furnished such lessor's or holder's
last address to Tenant, and until a reasonable period for remedying such act or
omission shall have elapsed following the giving of such notices and following
the time when such lessor or holder shall have become entitled under such
mortgage or ground lease, as the case may be, to remedy the same, during which
time such lessor or holder shall have the right, but shall not be obligated, to
remedy or cause to be remedied such act or omission. Tenant shall not exercise
any right pursuant to this Section 26.02 if the holder of any mortgage or such
aforesaid lessor commences to cure such aforesaid act or omission within a
reasonable time and diligently prosecutes such cure thereafter.

      25.8. Landlord shall, within 30 days of Tenant's request therefor, deliver
a written agreement to Tenant, or any other firm, person or corporation

such modification, (ii) whether Tenant is in default beyond any applicable grace
period, and (iii) the amount of fixed annual rent payable under this Lease, and

                     LEGAL PROCEEDINGS WAIVER OF JURY TRIAL

proceeding or counterclaim brought by either of the parties hereto against the
other on any matters whatsoever arising out of or in any way connected with this
Lease, the relationship of Landlord and Tenant, Tenant's use or occupancy of the
demised premises, and/or any other claims (except claims for personal injury or
property damage), and any emergency statutory or any other statutory remedy. It
is further mutually agreed that in the event Landlord commences any summary
proceeding for non payment of rent, Tenant will not interpose and does hereby
waive the right to interpose any counterclaim of whatever nature or description
in any such proceeding unless the failure to interpose such counterclaim shall
result in its waiver.

                              SURRENDER OF PREMISES

<PAGE>

      27.1. Upon the expiration or other termination of the term of this Lease,
(i) Tenant shall quit and surrender to Landlord the demised premises, broom
clean, in good order and condition, ordinary wear and tear (the provisions of
Section 7.01 hereof notwithstanding, i.e., to the extent that the demised
premises show signs of ordinary wear and tear upon such expiration or
termination, Tenant is not expected to restore or improve the same to eliminate
such signs) and damage by fire, the elements or other casualty excepted, and
shall remove all of its property as herein provided and (ii) with respect to
estimated payments or overpayments as to which Tenant may, pursuant to Article 3
hereof, be entitled to a refund, Landlord shall, within periods consistent with
Article 3, (A) determine the amounts, if. any, held by Landlord and owed to
Tenant and (B) pay such amounts to Tenant. Landlord's and Tenant's obligations
to observe or perform this covenant shall survive the expiration or other
termination of the term of this Lease.

                              RULES AND REGULATIONS

      28.1. Tenant and Tenant's servants, employees and agents shall observe
faithfully and comply strictly with the Rules and Regulations set forth in
Exhibit D attached hereto and made part hereof entitled "Rules and Regulations"
and such other and further reasonable Rules and Regulations as Landlord or
Landlord's agents may from time to time adopt provided, however, that in case of
any conflict or inconsistency between the provisions of this Lease and of any of
the Rules and Regulations as originally or as hereafter adopted, the provisions
of this Lease shall control. Reasonable written notice of any additional Rules
and Regulations shall be given to Tenant.

Nothing in this Lease contained shall be construed to impose upon Landlord any
duty or obligation to enforce the Rules and Regulations or the terms, covenants
or conditions in any other lease, against any other tenant of the Building, and
Landlord shall not be liable to Tenant for violation of the same by any other
tenant, its servants, employees, agents, visitors or licensees. Landlord shall
not enforce the Rules and Regulations against Tenant so that the Rules and
Regulations are applied against Tenant in an unreasonably discriminatory manner.

                                   ARTICLE 29

                             CONSENTS AND APPROVALS

      29.1. (a)   Wherever in this Lease Landlord's consent or approval is
                  required, if Landlord shall delay or refuse such consent or
                  approval, Tenant in no event shall be entitled to make, nor
                  shall Tenant make, any claim, and Tenant hereby waives any
                  claim, for money damages (nor shall Tenant claim any money
                  damages by way of set-off, counterclaim or defense) based upon
                  any claim or assertion by

<PAGE>

                  Tenant that Landlord unreasonably withheld or unreasonably
                  delayed its consent or approval. Tenant's sole remedy shall be
                  an action or proceeding to enforce any such provision, for
                  specific performance, injunction or declaratory judgment
                  provided, however, that Tenant shall not be deemed to have
                  waived a claim for damages if there is a final judicial
                  determination from which time for appeal has been exhausted
                  that Landlord acted maliciously or in bad faith in exercising
                  its judgement or withholding its consent or approval despite
                  its agreement to act reasonably, in which case Tenant shall
                  have the right to make a claim for the actual money damages
                  incurred by Tenant, but in no event shall Landlord be liable
                  for consequential or indirect damages.

            (b) Wherever in this Lease Tenant's consent or approval is required,
      if Tenant shall delay or refuse such consent or approval, Landlord in no
      event shall be entitled to make, nor shall Landlord make, any claim, and
      Landlord hereby waives any claim, for money damages (nor shall Landlord
      claim any money damages by way of set-off, counterclaim or defense) based
      upon any claim or assertion by Landlord that Tenant unreasonably withheld
      or unreasonably delayed its consent or approval. Landlord's sole remedy
      shall be an action or proceeding to enforce any such provision, for
      specific performance, injunction or declaratory judgment provided,
      however, that Landlord shall not be deemed to have waived a claim for
      damages if Tenant shall, in denying the consent, be found by a court of
      final jurisdiction to have acted in bad faith or with malice but in no
      event shall Tenant be liable for consequential or indirect damages.

                                     NOTICES

      30.1. Any notice or demand, consent, approval or disapproval, or statement
required to be given by the terms and provisions of this Lease, or by any law or
governmental regulation, either by Landlord to Tenant or by Tenant to Landlord,
shall be in writing. Unless otherwise required by such law or regulation, such
notice or demand shall be given, and shall be deemed to have been served and
given (x) two (2) Business Days after such notice or demand is mailed by
registered or certified mail deposited enclosed in a securely closed post paid
wrapper, in a United States Government general or branch post office, or
official depository with the exclusive care and custody thereof, (y) one
Business Day after such notice or demand is sent by a nationally recognized

Connecticut 06904 2305, Attention: Brian R. Smith, Esq. Either party may, by
notice as aforesaid, designate a different address or addresses for notices,
demands, consents, approvals or disapprovals.

      30.2. In addition to the foregoing, either Landlord or Tenant may, from
time to time, request in writing that the other party serve a copy of any notice
or demand, consent, approval or disapproval, or statement, on one other person
or entity designated in such request, such service to be effected as provided in
Section 31.01 hereof.

                                   ARTICLE 31

                                    NO WAIVER

      31.1. No agreement to accept a surrender of this Lease shall be valid
unless in writing signed by Landlord. No employee of Landlord or of Landlord's
agents shall have any power to accept the keys of the demised premises prior to
the termination of this Lease. The delivery of keys to any employee of Landlord
or of Landlord's agent shall not operate as a termination of this Lease or a
surrender of the demised premises. In the event of Tenant at any time desiring
to have Landlord sublet the premises for Tenant's account, Landlord or
Landlord's agents are authorized to receive said keys for such purpose without
releasing Tenant from any of the obligations under this Lease. The failure of
Landlord to seek redress for violation of, or to insist upon the strict
performance of, any covenant or condition of this Lease or any of the Rules and
Regulations set forth herein, or hereafter adopted by Landlord, shall not
prevent a subsequent act, which would have originally constituted a violation,
from having all the force and effect of an original violation. The receipt by
Landlord of rent with knowledge of the breach of any covenant of this Lease
shall not be deemed a waiver of such breach. The failure of Landlord to enforce
any of the Rules and Regulations set forth herein, or hereafter adopted, against
Tenant and/or any other tenant in the Building shall not be deemed a waiver of
any such Rules and Regulations. No provision of this Lease shall be deemed to
have been waived by Landlord, unless such waiver be in writing signed by
Landlord. No payment by Tenant or receipt by Landlord of a lesser amount than
the monthly rent herein stipulated shall be deemed to be other than on the
account of the earliest stipulated rent, nor shall any endorsement or statement
on any check or any letter accompanying any check or payment of rent be deemed
an accord and satisfaction, and Landlord may accept such check or payment
without prejudice to Landlord's right to recover the balance of such rent or
pursue any other remedy in this Lease provided.

      31.2. This Lease contains the entire agreement between the parties, and
any executory agreement hereafter made shall be ineffective to change, modify,
discharge or effect an abandonment of it in whole or in part unless such
executory agreement is in writing and signed by the party against whom
enforcement of the change, modification, discharge or abandonment is sought.

      32.1. The captions are inserted only as a matter of convenience and for

persons, individually and as co-partners of a partnership) or if Tenant's
interest in this Lease shall be assigned to a partnership (or to two (2) or more
persons, individually and as co-partners of a partnership) pursuant to Article
11 hereof (any such partnership and such persons are referred to in this Section
33.02 as "Partnership Tenant"), the following provisions of this Section 33.02
shall apply to such Partnership Tenant:

            (a) the liability of each of the parties comprising Partnership
      Tenant shall be joint and several, and

            (b) each of the parties comprising Partnership Tenant hereby
      consents in advance to, and agrees to be bound by, any written instrument
      which may hereafter be executed, changing, modifying or discharging this
      Lease, in whole or in part, or surrendering all or any part of the demised
      premises to Landlord, and by notices, demands, requests or other
      communications which may hereafter be given, by Partnership Tenant or any
      of the parties comprising Partnership Tenant, and

            (c) any bills, statements, notices, demands, requests or other
      communications given or rendered to Partnership Tenant or to any of the
      parties comprising Partnership Tenant shall be deemed given or rendered to
      Partnership Tenant and to all such parties and shall be binding upon
      Partnership Tenant and all such parties, and

            (d) if Partnership Tenant shall admit new partners, all of such new
      partners shall by their admission to Partnership Tenant, be deemed to have
      assumed performance of all of the terms, covenants and conditions of this
      Lease on Tenant's part to be observed and performed, and

            (e) Partnership Tenant shall give prompt notice to Landlord of the
      admission of any such new partners, and upon demand of Landlord, shall
      cause each such new partner to execute and deliver to Landlord an
      agreement in form satisfactory to Landlord, wherein each such new partner
      shall assume performance of all of the terms, covenants and conditions of
      this Lease on Tenant's part to be observed and performed (but neither
      Landlord's failure to request any such agreement nor the failure of any
      such new partner to execute or deliver any such

                              INABILITY TO PERFORM

      33.1. If, by reason of (l) strike, (2) labor troubles, (3) governmental
preemption in connection with a national emergency, (4) any rule, order or
regulation of any governmental agency, (5) conditions of supply or demand which
are affected by war or other national, state or municipal emergency, or any
other cause or (6) any cause beyond Landlord's reasonable control, Landlord
shall be unable to fulfill its obligations under this Lease or shall be unable
to supply any service which Landlord is obligated to supply, Landlord shall not
be deemed in default hereunder and this Lease and Tenant's obligation to pay
rent hereunder shall, except as provided in Section 34.03 hereof, in no wise be
affected, impaired or excused.

      33.2. If by reason of the circumstances contemplated by clauses (1)
through (5) of Section 34.01 hereof, Tenant shall be unable to fulfill any of
its obligation under this Lease other than the obligations to make any payment
of rent, additional rent or other charges, Tenant shall not be deemed in default
hereunder for so long as such circumstances continue to prevent Tenant from
fulfilling such obligations.

      33.3. If as a consequence of a circumstance or event contemplated by
Section 34.01 hereof or the performance by Landlord of any repair, alteration,
addition or improvement, the demised premises become untenantable and Tenant
actually discontinues the use thereof for a period in excess of ten (10)
Business Days, then, commencing on the eleventh (11th) Business Day of such
untenantability and continuing thereafter until the earlier of the date that (i)
the tenantability of the demised premises is restored, or (ii) Tenant resumes
occupancy of all or any portion of the demised premises for the conduct of its
business, the fixed annual rent and additional rent payable pursuant to Articles
3 and 4 hereof, shall be abated.

                         NO REPRESENTATIONS BY LANDLORD

      34.1. Landlord or Landlord's agents have made no representations or
promises with respect to the Building or demised premises except as herein
expressly set forth.

      35.1. Landlord shall have the full right at any time to name and change
the name of the Building and to change the designated address of the Building.
The Building may be named after any person, firm, or otherwise, whether or not

                               MEMORANDUM OF LEASE

      39.1. Tenant shall, at the request of Landlord execute and deliver a
statutory form of memorandum of this Lease for the purpose of recording, but
said memorandum of this Lease shall not in any circumstances be deemed to modify
or to change any of the provisions of this Lease.

                                  MISCELLANEOUS

of Tenant, not dependent on any other provision of this Lease.

      40.7. (a) If the demised premises or any additional space to be included
within the demised premises shall not be available for occupancy by Tenant on
the specific date hereinbefore designated for the commencement of the term of
this Lease or for the inclusion of such space for any reason whatsoever, then
this Lease shall not be affected thereby but, in such case, said specific date
shall be deemed to be postponed until the date when the demised premises or such
additional space shall be available for occupancy by Tenant, and Tenant shall
not be entitled to possession of the demised premises or such additional space
until the same are available for occupancy by Tenant, provided, however, that
Tenant shall have no claim against Landlord, and Landlord shall have no
liability to Tenant by reason of any such postponement of said specific date,
and the parties hereto further agree that any failure to have the demised
premises or such additional space available for occupancy by Tenant on said
specific date or on the Commencement Date shall in no wise affect the
obligations of Tenant hereunder nor shall the same be construed in any wise to
extend the term of this Lease.

            (b) Notwithstanding anything to the contrary contained in this
      Lease, the demised premises shall be deemed available for occupancy by
      Tenant on the Commencement Date notwithstanding that a portion of the
      Second (2nd) Floor West of the Building shall be occupied by Continental
      Plastic Containers, Inc. (hereinafter called "Plastic"). Tenant
      acknowledges that actual occupancy of such portion by Tenant shall be a
      matter to be agreed or resolved by Tenant and Plastic, and Landlord shall
      have no responsibility therefor. Nor shall the rent payable hereunder be
      affected thereby.

      40.8. In the event that Tenant is in arrears in payment of fixed annual
rent or additional rent hereunder, Tenant waives Tenant's right, if any, to
designate the items against which any payments made by Tenant are to be
credited, and Tenant agrees that Landlord may apply any payments made by Tenant
to any items it sees fit, irrespective of and notwithstanding any designation or
request by Tenant as to the items against which any such payments shall be
credited.

      40.9. Landlord and Tenant each represent that it has full corporate
authority to enter into this Lease and perform its obligations hereunder.

copies of leases of certain other tenants in the Building and agrees that it
shall not disclose the terms of such leases to any third parties.

the arbitration process provided for herein by giving notice to that effect to
the other, and the party so initiating the appraisal process (such party
hereinafter referred to as the "Initiating Party") shall specify in such notice
the name and address of the person designated to act as an arbitrator on its
behalf. Within thirty (30) days after the designation of such arbitrator, the
other party (hereinafter referred to as the "Other Party") shall give notice to
the Initiating Party specifying the name and address of the person designated to
act as an arbitrator on its behalf. If the Other Party fails to notify the
Initiating Party of the appointment of its arbitrator within the time above
specified, then the appointment of the second arbitrator shall be made in the
same manner as hereinafter provided for the appointment of a third arbitrator in
a case where the two arbitrators appointed hereunder and the parties are unable
to agree upon such appointment. The two arbitrators so chosen shall meet within
ten (10) days after the second arbitrator is appointed and if, within sixty (60)
days after the second arbitrator is appointed, the two arbitrators shall not

<PAGE>

In the event of their being unable to agree upon such appointment within eighty
(80) days after the appointment of the second arbitrator, the third arbitrator
shall be selected by the parties themselves if they can agree thereon within a
further period of fifteen (15) days. If the parties do not so agree, then either
party, on behalf of both and on notice to the other, may request such
appointment by the American Arbitration Association (or organization successor
thereto) in accordance with its rules then prevailing or if the American
Arbitration Association (or such successor organization) shall fail to appoint
said third arbitrator within fifteen (15) days after such request is made, then
either party may apply on notice to the other, to the Superior Court Judicial
District of Stamford/Norwalk at Norwalk Housing Session, Connecticut (or any
other court having jurisdiction and exercising functions similar to those now
exercised by said Court) for the appointment of such third arbitrator.

      46.5. Each party shall pay the fees and expenses of the one of the two
original arbitrators appointed by or for such party, and the fees and expenses

parties equally.

      46.6. The majority of the arbitrators shall determine the fair market rent
of the demised premises and render a written certified report of their
determination to both Landlord and Tenant within sixty (60) days of the
appointment of the first two arbitrators or sixty (60) days from the appointment
of the third arbitrator if such third arbitrator is appointed pursuant to
Section 47.04, and the fair market rent, so determined, shall be applied to
determine as above provided, whether the fixed annual rent shall be increased
pursuant to clause (i) of Section 47.02 hereof for the Second Extension Term. In
determining the fair market rent under this Article 47, the arbitrators shall
make the assumption that the length of the extension term hereunder (whether or
not the same is the case) is for a term length for which Landlord would, under
the then market conditions, be able to obtain the maximum rental amount.

      46.7. Each of the arbitrators selected as herein provided shall have at
least ten (l0) years experience in the leasing and renting of office space on
behalf of landlords in first class office buildings in Fairfield County,
Connecticut.

      46.8. If Landlord notifies Tenant that the fixed annual rent for the
Second Extension Term shall be equal to the amount set forth in clause (ii) of

                     SECOND AMENDMENT TO AGREEMENT OF LEASE

      THIS SECOND AMENDMENT TO AGREEMENT OF LEASE (this "Amendment") is
effective as of April 18, 1997, by and between STATE OF CALIFORNIA PUBLIC
EMPLOYEES' RETIREMENT SYSTEM, an Agency of the State of California ("Landlord"),
and OXFORD HEALTH PLANS, INC., a Delaware corporation ("Tenant"), with reference
to the following facts:

      A. Landlord's predecessor in interest, THE PRUDENTIAL INSURANCE COMPANY OF
AMERICA, a New Jersey Corporation ("Prudential"), as landlord, and Tenant, as
tenant, entered into that certain Agreement of Lease, dated as of June 16, 1993
(the "Original Lease"), as amended by that certain First Amendment to Lease,
dated as of May 26, 1995 (the "First Amendment," and together with the Original
Lease, the "Lease"). Each capitalized term used in this Amendment, but not
defined herein, shall have the meaning ascribed to it in the Lease.

      B. The demised premises under the Lease as of the date of this Amendment
consist of approximately 169,366 rentable square feet ("RSF") located in the
Building (the "Original Demised Premises").

      C. Landlord and Tenant desire to enter into this Amendment to expand the
demised premises by adding approximately 24,405 RSF located on the second floor
of the north wing of the Building (the "Expansion Space," and together with the
Original Demised Premises, the "Demised Premises" or "demised premises"), and to
make other related changes to the Lease, all as more particularly set forth in
this Amendment.

      THEREFORE, Landlord and Tenant agree that the Lease shall be amended as
follows:

      1. Premises.

      (a) Section 1.01 of the Lease shall be amended by expanding the Original
Demised Premises to include the Expansion Space, which Expansion Space is more
particularly depicted on Exhibit A attached hereto and incorporated herein.
Landlord and Tenant hereby agree that Landlord shall deliver exclusive
possession of the Expansion Space to Tenant, vacant and broom clean. Tenant
agrees to accept the Expansion Space "as is," and Tenant agrees that Landlord
has no obligation to demolish or construct any improvements in the Expansion
Space.

      (b) All references in the Lease to any number of square feet as the deemed
"rentable square foot area of the demised premises" (including, without
limitation, those references in Section 3.02(f) and Section 4.02(d)) shall be
deleted and replaced with "193,771 square feet."

                                      -1-
<PAGE>

      (c) Tenant is permitted to occupy the Expansion Space upon execution of
this Amendment by both parties, which occupancy shall be on all of the terms and
conditions of the Lease as amended by this Amendment; provided, however,
notwithstanding anything contained herein or in the Lease to the contrary,
Tenant shall not be obligated to pay any fixed annual rent with respect to the
Expansion Space prior to May 8, 1997.

      2. Term. Section 1.01 of the Lease shall be further amended by deleting
the last clause of that section (commencing with the words, "; for a term to
commence") and replacing it with the following:

            "; the term for the Original Demised Premises (as defined in that
      certain Second Amendment to Agreement of Lease (the "Second Amendment")
      dated as of April 18, 1997 between Landlord and Tenant) shall commence on
      July 1, 1993 (hereinafter referred to as the "Commencement Date") and
      shall expire on February 28, 2001 (hereinafter referred to as the
      "Expiration Date") or until such term shall sooner cease or terminate or
      be extended as hereinafter provided. The term for the Expansion Space (as
      defined in the Second Amendment) shall commence on April 18, 1997 and
      expire on February 28, 2010 (the "Expansion Space Expiration Date");
      provided, however, the term for the Expansion Space shall automatically
      terminate prior to the Expansion Space Expiration Date and coterminously
      with the expiration or earlier termination of this Lease with respect to
      the Original Demised Premises if this Lease terminates pursuant to the
      terms of this Lease with respect to the Original Demised Premises or in
      the event that this Lease expires prior to the Expansion Space Expiration
      Date due to Tenant's failure to exercise timely any option to extend the
      term for the Original Demised Premises."

      3. Rent.

      (a) The following new section shall be added to Article 1 of the Lease:

            "52.01. Landlord hereby grants Tenant an irrevocable license,
      throughout the term of this Lease as the same may be extended, to use
      approximately one hundred (100) usable square feet of space for storage
      use, such space to be located on the lower level of the Building (the
      "Storage Space"), which Storage Space is more particularly depicted on
      Exhibit B attached hereto and incorporated herein. Tenant shall use the
      Storage Space only for "dead" storage of files, documents, furniture,
      trade fixtures and similar items, and any other use, including without
      limitation using the Storage Space as a work space or for operating
      equipment, is prohibited. Landlord has the right to relocate the Storage
      Space to another comparable storage space in the Building that has at
      least fifty (50) usable square feet, in a location that is reasonably
      satisfactory to Tenant, at any time upon twenty (20) business days prior
      written notice to Tenant, at Landlord's sole reasonable cost and expense.

            "52.02. Tenant's use of the Storage Space shall be on all of the
      terms and conditions of this Lease as amended by the Second Amendment;
      provided, however, Tenant shall not be obligated to pay any rent or
      additional rent with respect to its use of the Storage Space, and provided
      that Landlord shall have no obligations under Articles 12 or 21 of this
      Lease with respect to the Storage Space. Notwithstanding the foregoing,
      (1) Tenant shall have access

                                      -6-
<PAGE>

      to the storage space on a 24-hour day, seven-day per week basis and (2)
      Landlord shall not remove or alter any existing electrical lights, outlets
      or other electrical equipment existing in the Storage Space. Tenant shall
      not alter or add to any such electrical equipment without Landlord's prior
      written consent, which shall not be unreasonably withheld (based upon
      Landlord's reasonable determination of electrical equipment typically
      provided for comparable storage spaces). If Landlord consents thereto,
      then Landlord shall install such additional electrical equipment at
      Tenant's sole cost and expense, which cost and expense shall not be
      unreasonable.

            "52.03. Tenant's license to use the Storage Space pursuant to this
      Article shall automatically terminate upon the termination of this Lease,
      and Tenant shall vacate the Storage Space and surrender the Storage Space
      to Landlord clean and free of debris and in good state of repair, ordinary
      wear and tear and damage by fire or other casualty excepted. Ordinary wear
      and tear shall not include any damage or deterioration that would have
      been prevented by good maintenance practice by Tenant."

not incurred any liability for any commission or fee to any investment advisor,
real estate broker or finder, including, without limitation, Carson Crane

and hold Landlord harmless from all claims, liabilities, losses, damages, costs
and expenses (including, without limitation, reasonable attorneys' fees) arising
from or based on any obligation or alleged obligation of Tenant to pay any such
commission or fee in connection with this Amendment. Tenant also represents and
warrants to Landlord that (1) no commissions or fees are due to Tenant (or any
broker or finder) with respect to this Amendment in connection with or arising
out of that certain Commission Assignment and Release Agreement (the "Commission
Agreement") dated June 24, 1993, entered into among CCI, API, Prudential and
Tenant, and (2) notwithstanding the provisions of the Commission Agreement
regarding payment of a Renewal Commission or an Expansion Commission (as those
terms are defined in the Commission Agreement), no commissions or fees will be
due to Tenant (or any broker or finder) in connection with or arising out of the
Commission Agreement with respect to the Expansion Space in the event Tenant
exercises a right under the Lease to extend or renew the term of the Lease with
respect to the Original Demised Premises. Furthermore, in the event CCI or API,
or any successors in interest thereto, makes any claim for any commission or fee
pursuant to the Commission Agreement (i) in connection with this Amendment, or
(ii) in connection with any Renewal Commission or Expansion Commission to the
extent that

                                      -7-
<PAGE>

such claim pertains or relates to the Expansion Space, Tenant shall indemnify,
defend and hold Landlord harmless from all claims, liabilities, losses, damages,
costs and expenses (including, without limitation, reasonable attorneys' fees)
arising from or based on any obligation or alleged obligation of Tenant or
Landlord to pay any such commission or fee.

      Notwithstanding the foregoing, the obligations of the parties under the
Commission Agreement with respect to any Renewal Commission or Expansion
Commission relating to the Original Demised Premises shall not be modified
hereby.

      Landlord represents and warrants to Tenant that Landlord has not incurred
any liability for any commission or fee to any investment advisor, real estate
broker or finder in connection with this Amendment, other than to Jones Lang
Wootton ("JLW"). Any commission or fee that Landlord owes to JLW shall be paid
in accordance with the terms of a separate agreement between Landlord and JLW.

Lease and this Amendment.

agrees that (i) it shall only increase such charges in proportion to increases
in Landlord's actual cost of rendering such services and (ii) in the event that
it shall be increasing the same it shall notify Tenant thereof in writing prior
to doing so.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES
                             OF THE SECURITYHOLDERS

            Each Securityholder severally, but not jointly, represents and

company or partnership duly incorporated or organized, validly existing and in

Such Securityholder is duly licensed or qualified to do business and is in good
standing in each jurisdiction in which the properties owned or leased by it or
the operation of its business makes such licensing or qualification necessary,
except to the extent that the failure to be so licensed or qualified would not
prevent or materially hinder the performance of the actions contemplated by this
Agreement. The execution and delivery of this Agreement by such Securityholder,
the performance by it of its obligations hereunder and the performance by it of
the actions contemplated hereby have been duly authorized by all requisite
action on its part. This Agreement has been duly executed and delivered by such
Securityholder, and (assuming due authorization, execution and delivery by the
other Persons signatory thereto) this Agreement constitutes a legal, valid and
binding obligation of such Securityholder enforceable against it in accordance
with its terms.

            SECTION 3.02. No Conflict. Assuming that all consents, approvals,
authorizations and other actions described in Section 3.03 have been obtained,
the execution, delivery and performance of this Agreement by such Securityholder
do not and will not (a) violate, conflict with or result in the breach of any
provision of its Charter or By-laws (or similar organizational documents), to
the extent it has such, (b) conflict with or violate any law,

                                       12
<PAGE>

governmental regulation or governmental order applicable to such party or any of
its assets, properties or businesses or (c) conflict with, result in any breach
of, constitute a default (or event which with the giving of notice or lapse of
time, or both, would become a default) under, require any consent under, or give
to others any rights pursuant to, any contract, agreement or arrangement by
which such party is bound; except to the extent that any conflict under (b) or
(c) above would not prevent or materially hinder the performance of the actions
contemplated by this Agreement.

            SECTION 3.03. Governmental Consents and Approvals. The execution,
delivery and performance of this Agreement by such party do not and will not
require any consent, approval, authorization or other order of, action by,
filing with or notification to, any governmental authority, except such as may
be required by the HSR Act, applicable.

                                   ARTICLE IV

                              CORPORATE GOVERNANCE

            SECTION 4.01. Agreement to Vote. The Securityholders agree to vote
their shares, and the Company agrees to take all necessary measures, in order to
carry out the agreements set forth in this Article IV, and to prevent any action
by the Company's Securityholders that is inconsistent with such agreements,
until the Priceline Warrant expires unexercised. Thereafter, the Agreements
contained in this Article IV shall be of no further effect.

            SECTION 4.02. Size of Board. Initially, the Board shall consist of
seven (7) directors. If Priceline shall exercise the Priceline Warrant for not
less than 75% of the Warrant Shares, and as a result shall hold a majority of
the then outstanding Shares, the number of directors on the Board shall be
increased to nine (9). The number of directors shall not exceed nine (9), unless
the Board of Directors shall vote to increase the number in accordance with
Section 4.06.

            SECTION 4.03. Composition of Board. (a) Initially, Priceline shall
be represented by one (1) director, Walker Digital shall be represented by one
(1) director, Jonathan Otto shall be represented by one (1) director, Vulcan
shall be represented by one (1) director and Goldman Sachs shall be represented
by one (1) director. In addition, there shall be two independent directors (the
"Independent Directors"), elected by Goldman Sachs, Arista Capital Partners, LP
("Arista Capital"), Michael Loeb and Jonathan Otto, voting on an equal basis
without reference to proportionate Shares ownership. Both such directors shall
qualify as "independent directors" pursuant to the definition set forth in Rule
4200(a)(14) of the National Association of Securities Dealers, substituting the
word "affiliate" for "subsidiaries" therein.

                                       13
<PAGE>

            (b) If and when the Board is expanded to nine (9) members, as
provided in Section 4.02, Priceline shall be represented by five (5) directors,
Walker Digital by one (1) director and Vulcan by one (1) director. The remaining
two (2) directors (the "Majority Directors") shall be elected by all the
Securityholders (excluding Priceline), voting cumulatively in proportion to
Share ownership. A representative of each of Goldman Sachs, Jonathan Otto and
Arista Capital may attend meetings of the Board in a nonvoting capacity and at
their own expense; provided that (i) no such representative shall serve in a
similar capacity or as a director or employee for any other company that is in a
business similar to that of the Company or that could be considered a competitor
of the Company and (ii) such representative shall keep all business of the Board
in the strictest confidence and, or requested by the Company, enter into a
confidentiality agreement.

            SECTION 4.04. Nomination and Election of Directors. The
Securityholders' initial nominees for the Board shall be as set forth in
Schedule III hereto. If not already named by the Company's existing Board, the
Securityholders shall act to elect such nominees as directors as soon as
practicable by unanimous written consent or at a shareholders' meeting to be
held hereafter. Hereafter, the Securityholders shall make the nominations to
which they are entitled hereunder not later than 30 days prior to each annual
meeting of the Company's shareholders, and the Board shall be elected at such
meeting or by unanimous written consent in accordance herewith.

            SECTION 4.05. Vacancies. If, as a result of death, disability,
retirement, resignation, removal (with or without cause) or otherwise, there
shall exist or occur any vacancy in the Board:

            (a) if the departed director was nominated by Priceline, then
      Priceline,

            (b) if the departed director was nominated by Walker Digital, then
      Walker Digital,

            (c) if the departed director was nominated by Jonathan Otto, then
      Jonathan Otto,

            (d) if the departed director was nominated by Goldman Sachs, then
      Goldman Sachs,

            (e) if the departed director was nominated by Vulcan, then Vulcan,
      and

            (f) if the departed director was an independent director nominated
      by Goldman Sachs, Arista Capital, Michael Loeb and Jonathan Otto, then
      Goldman Sachs, Arista Capital, Michael Loeb and Jonathan Otto,
      collectively,

                                       14
<PAGE>

shall be entitled to designate in writing one nominee for election to fill such
vacancy. The Securityholders shall as soon as practicable after such nomination
is made act to elect such nominee to the Board. Any director elected pursuant to
this Section 4.05 shall serve until the next annual election of directors.

            SECTION 4.06. Voting. The Company's By-Laws shall provide that,
prior to the expiration unexercised of the Priceline Warrant, the affirmative
vote of the director or directors nominated by Priceline is required to approve
any of the following actions:

            (a) prior to the third anniversary of the Closing, any
      Recapitalization, business combination or sale of all or substantially all
      of the assets of the Company in which more than 50% of Company's Voting
      Interests are transferred;

            (b) any amendment, supplement or modification of any kind whatsoever
      to the Company's Certificate of Incorporation or By-laws, including any
      increase in the number of directors on the Board;

            (c) prior to the third anniversary of the Closing, the filing of a
      registration statement under the Securities Act or the making of any other
      public disclosure in connection with the commencement of an Initial Public
      Offering (excluding, for purposes of this paragraph only, the requirement
      that proceeds therefrom exceed $50 million); provided that such vote shall
      not be required in connection with an Initial Public Offering pursuant to
      Section 6.02(a);

            (d) any transactions with an Affiliate of the Company other than at
      fair market value in the ordinary course of business;

            (e) the dissolution and winding up of the Company; and

            (f) the voluntary initiation of an Insolvency Event in respect of
      the Company.

            The Securityholders shall vote their Shares in accordance with
Priceline's request on the above issues at any meeting of the Securityholders
where any of the above items are voted upon. Moreover, the Securityholders
hereby agree not to vote their shares in favor of any change to the By-laws of
the Company inconsistent with this Section 4.06.

            SECTION 4.07. Audit Committee. The Company shall establish and
maintain an Audit Committee, which shall consist of three members of the Board,
including the director nominated by Vulcan, the director nominated by Walker
Digital and, prior to an increase in the size of the Board pursuant to Section
4.03, one Independent Director, or, following an increase in the size of the
Board pursuant to Section 4.03, one Majority Director.

                                       15
<PAGE>

            SECTION 4.08. Compensation Committee. The Company shall establish
and maintain a Compensation Committee of the Board. The Compensation Committee
shall make recommendations to the full Board for such matters as management
compensation, Company benefit plans, and matters relating to the Company's
option plans, if any. The Compensation Committee shall consist of three members
of the Board, including the director nominated by Vulcan, the director nominated
by Walker Digital and, prior to an increase in the size of the Board pursuant to
Section 4.03, one Independent Director, or, following an increase in the size of
Board pursuant to Section 4.03, one Majority Director.

                                    ARTICLE V

                               TRANSFER OF SHARES

            SECTION 5.01. General Restriction. No Securityholder shall, directly
or indirectly, make or solicit any Sale of, or create, incur, solicit or assume
any Encumbrance with respect to, any Share, except in compliance with the
Securities Act and this Agreement.

            SECTION 5.02. Legends. (a) The Company shall affix to each
certificate evidencing Shares issued to Securityholders a legend in
substantially the following form:

            "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
            UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, PLEDGED OR
            OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE REGISTRATION
            REQUIREMENTS OF THE SECURITIES ACT OF 1933 OR AN EXEMPTION THEREFROM
            AND, IN EACH CASE, IN COMPLIANCE WITH APPLICABLE STATE SECURITIES
            LAWS.

            THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
            RESTRICTIONS ON TRANSFER AS SET FORTH IN A SECURITYHOLDERS_
            AGREEMENT DATED AS OF _______, 1999, AS IT MAY BE AMENDED FROM TIME
            TO TIME, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL EXECUTIVE
            OFFICES OF THE ISSUER. NO REGISTRATION OF TRANSFER OF THESE SHARES
            WILL BE MADE ON THE BOOKS OF THE ISSUER UNLESS AND UNTIL SUCH
            RESTRICTIONS SHALL HAVE BEEN COMPLIED WITH."

                                       16
<PAGE>

            (b) Any Securityholder with Shares issued prior to the date hereof
has delivered to the Company its certificates representing such Shares in
exchange for certificates representing such Shares bearing the legend set forth
in Section 5.02(a).

            (c) In the event that any Shares shall cease to be Restricted
Shares, the Company shall, upon the written request of the holder thereof, issue
to such holder a new certificate evidencing such Shares without the first
paragraph of the legend required by Section 5.02(a) endorsed thereon. In the
event that the Shares shall cease to be subject to the restrictions on transfer
set forth in this Agreement, the Company shall, upon the written request of the
holder thereof, issue to such holder a new certificate evidencing such Shares
without the legend required by the second paragraph of Section 5.02(a). Before
issuing a new certificate omitting part or all of the legend set forth in
Section 5.02(a), the Company may request an opinion of counsel reasonably
satisfactory to it to the effect that the restrictions discussed in the legend
to be omitted no longer apply to the Shares represented by such certificate.

            SECTION 5.03. Certain Restrictions on Transfer. (a) No
Securityholder shall, directly or indirectly (through the transfer of capital
stock of any Person that holds, or controls any Person that holds, such Shares)
make or solicit any Sale of, or create, incur or assume any Encumbrance with
respect to, any Share of Common Stock Beneficially Owned by such Securityholder,
other than

            (i) any Sale to a Permitted Transferee,

            (ii) during the Restricted Period, any Sale of Common Stock that is
      made in compliance with the procedures, and subject to the limitations,
      set forth in Sections 5.04 and 5.05,

            (iii) subject to compliance with Section 6.03(b), any Sale of Common
      Stock subsequent to the date that is 180 days after closing of the
      Company's Initial Public Offering,

            (iv) any Sale in connection with a merger of the Company or a Sale
      of all or substantially all of its assets or other similar business
      combination that has been approved by the Company's Board of Directors,

            (v) any Sale in connection with the merger of Priceline or a Sale of
      all or substantially all of its assets or other similar business
      combination that has been approved by Priceline's Board of Directors, or

            (vi) any Sale in connection with a public offering of equity
      securities of any Securityholder.

                                       17
<PAGE>

            Notwithstanding the foregoing, except as otherwise expressly
provided in this Agreement, all Sales permitted by the foregoing clauses (i)
through (iv) shall be subject to, and shall not be made other than in compliance
with, the provisions of Sections 5.01, 5.02, 5.03(b), 5.06 and 5.07.

            (b) No Sale of Shares to a Permitted Transferee shall be effective
if a purpose or effect of such transfer shall have been to circumvent the
provisions of this Section 5.03, Section 5.04 or Section 5.05. Each
Securityholder shall remain responsible for the performance of this Agreement by
each Permitted Transferee of such Securityholder to which Shares are
transferred, except if such Permitted Transferee received such Shares by will or
the laws of descent and distribution or if such Permitted Transferee is a
natural Person. If any Permitted Transferee to which Shares are transferred
pursuant to clause (i) of Section 5.03(a) is not a natural Person and ceases to
be a Permitted Transferee of the Securityholder from which or whom it acquired
such Shares pursuant to such provision, such Person shall reconvey such Shares
to such transferring Securityholder immediately before such Person ceases to be
a Permitted Transferee of such transferring Securityholder so long as such
Person knows of its upcoming change of status immediately prior thereto. If such
change of status is not known until after its occurrence, the former Permitted
Transferee shall make such transfer to such transferring Securityholder as soon
as practicable after the former Permitted Transferee receives notice thereof.

            (c) All restrictions on transfers of Shares imposed by this Article
V shall terminate 180 days after the closing of the Company's Initial Public
Offering or, if earlier, upon the expiration unexercised of the Priceline
Warrant.

            SECTION 5.04. Rights of First Refusal. (a) (i) If at any time during
the Restricted Period any Securityholder receives from or otherwise negotiates
with a Third Party a bona fide offer (an "Offer") to purchase for cash, Cash
Equivalents or Marketable Securities any of the Shares of Common Stock
Beneficially Owned or held by such Securityholder, and such Securityholder
intends to sell such Shares to such Third Party, such Securityholder (the
"Prospective Seller") shall provide the Company and each Securityholder other
than the Prospective Seller (each, an "Other Securityholder") with written
notice of such Offer (an "Offer Notice"). The Offer Notice shall identify the
Third Party making the Offer, the number of Shares covered by the Offer (the
"Offered Shares"), the price per Share at which a Sale is proposed to be made
(the "Offer Price"), the form of consideration proposed to be paid and all other
material terms and conditions of the Offer.

            (ii) If the Offer Price includes

            (A) any Marketable Securities, the value of such securities shall be
      determined by calculating a volume-weighted average of the closing prices
      of such securities over the ten trading-day period ending on the Price
      Determination Date on the market with the largest trading volume in such
      securities; or

                                       18
<PAGE>

            (B) any Cash Equivalents, the value of such Cash Equivalents shall
      be determined by reference to the closing price thereof on the market with
      the largest trading volume in such securities on the Price Determination
      Date.

            (b) (i) The receipt of an Offer Notice by the Company from a
Prospective Seller shall constitute an exclusive offer by such Prospective
Seller to sell to the Company any or all of the Offered Shares at the Offer
Price. Such offer shall remain open and irrevocable until expiration of thirty
days after receipt of such Offer Notice by the Company and the Other
Securityholders (the "Offer Period"). At any time prior to expiration of the
Offer Period, the Company shall have the right to accept the Prospective
Seller's offer as to any or all of the Offered Shares by giving a written notice
of election (the "Notice of Election") to the Prospective Seller with a copy to
the Other Securityholders.

            (ii) The receipt of an Offer Notice by the Other Securityholders
(excluding Priceline, whose rights are governed by subparagraph (b)(iii) below)
from a Prospective Seller shall constitute an offer by such Prospective Seller
to sell to such other Securityholders any or all of the Offered Shares not
purchased by the Company pursuant to subparagraph (b)(i) above at the Offer
Price pro rata, in accordance with the following formula. Each such Other
Securityholder shall be entitled to purchase, upon the terms specified in the
Offer Notice, a number of Shares equal to (x) the number of Offered Shares plus
the number of Shares being sold pursuant to Section 5.05 hereof, if any, less
the number of Shares the Company purchases pursuant to subparagraph (b)(i) above
multiplied by (y) a fraction, the numerator of which is the number of Voting
Interests Beneficially Owned by such Other Securityholder and the denominator of
which is the number of Voting Interests Beneficially Owned by all Other
Securityholders (excluding Priceline) who wish to purchase Offered Shares. If
any Other Securityholder wishes to purchase less than all the Shares such Other
Securityholder is entitled to purchase in accordance with the preceding
sentence, the Shares such Other Securityholder declines to purchase shall be
allocated among the Other Securityholders who wish to purchase such additional
Shares according to the same formula, mutatis mutandis. Each Other
Securityholder who wishes may accept the offer by sending a Notice of Election
to the Prospective Seller and the Company with a copy to the Other
Securityholders prior to expiration of the Offer Period. The Notice of Election
shall specify the maximum number of Shares an Other Securityholder is willing to
buy pursuant to this Section 5.04, if any, the number of Shares it wishes and is
entitled to sell pursuant to Section 5.05, if any, and any other terms and
conditions not inconsistent with this Agreement.

            (iii) The receipt of an Offer Notice by Priceline from a Prospective
Seller shall constitute an offer by such Prospective Seller to sell to Priceline
any or all of the Offered Shares at the Offer Price, to the extent such Shares
shall not have been purchased by the Company or the Other Securityholders
pursuant to subparagraphs (b)(i) and (b)(ii) above. Priceline may accept the
Prospective Seller's offer at any time prior to expiration of the Offer Period
by sending a

                                       19
<PAGE>

Notice of Election to the Prospective Seller and the Company, with a copy to the
Other Securityholders.

            (iv) If the Company or any Other Securityholder accepts the
Prospective Seller's offer in accordance with this Section 5.04(b) (an
"Accepting Party"), such Accepting Party shall purchase from the Prospective
Seller, and the Prospective Seller shall sell to such Accepting Party, such
number of Offered Shares as to which such Accepting Party shall have accepted
the Prospective Seller's offer pursuant to subparagraph (b)(i), (ii) or (iii)
above. The price per Share to be paid by such Accepting Party shall be the Offer
Price specified in the Offer Notice, payable in accordance with the terms of the
Offer; provided that the Accepting Party may pay the Offer Price with any
combination of cash, Cash Equivalents and Marketable Securities, to be valued as
provided in subparagraph (a)(ii) above.

            (c) The Prospective Seller and each Accepting Party shall select,
for consummation of the Sale of Offered Shares to such Accepting Party, a date
not later than 30 days (or longer, if the HSR Act so requires) after expiration
of the Offer Period. At the consummation of such Sale, the Prospective Seller
shall, against delivery by the relevant Accepting Party of the Offer Price
multiplied by the number of Shares being purchased by such Accepting Party, (i)
deliver to the Accepting Party certificates evidencing the Offered Shares being
sold plus the Shares being sold pursuant to Section 5.05, if any, duly endorsed
in blank or accompanied by written instruments of transfer in form satisfactory
to such Accepting Party duly executed by the Prospective Seller (or the selling
Other Securityholder, as the case may be) free and clear of any and all
Encumbrances (other than this Agreement), and (ii) assign all its rights under
this Agreement with respect to the Offered Shares being sold pursuant to an
instrument of assignment reasonably satisfactory to such Accepting Party.

            (d) In the event that (i) each Other Securityholder and the Company
shall have received an Offer Notice from a Prospective Seller but the
Prospective Seller shall not have received Notices of Acceptance indicating a
desire to purchase, in the aggregate, all the Offered Shares prior to expiration
of the Offer Period or (ii) an Accepting Party shall have given a Notice of
Election to the Prospective Seller but shall have failed to consummate, other
than as a result of the fault of the Prospective Seller, a purchase of the
Offered Shares he elected to purchase in such Notice of Election within the time
frame specified in paragraph (c) above (and neither the Company nor any Other
Securityholder shall have indicated an interest upon any such failure to buy
such Shares within ten Business Days of their receipt of a notice of such
failure from the Prospective Seller), then nothing in this Section 5.04 shall
limit the right of the Prospective Seller to make thereafter a Sale of, or
create an Encumbrance on, all Offered Shares not accepted for purchase by the
Company or the Other Securityholders pursuant to a Notice of Election; provided
that

                                       20
<PAGE>

            (A) the total number of Shares sold to the Company, the Other
      Securityholders and the Third Party who made the Offer shall be not less
      than the number of Offered Shares specified in the Offer Notice;

            (B) the total number of Shares sold by the Prospective Seller for
      his own account (i.e., not including Shares Beneficially Owned by Other
      Securityholders) to the Third Party who made the Offer shall be not more
      than the number of Offered Shares specified in the Offer Notice; and

            (C) all the Shares that are sold or otherwise disposed of by the
      Prospective Seller are sold (1) within 30 days (or longer, if the HSR Act
      so requires) after expiration of the Offer Period, (2) at an amount not
      less than the Offer Price included in such Offer Notice, (3) on the terms
      specified in the Offer Notice and (4) to the Third Party that made the
      Offer.

            (e) In the event that each Other Securityholder and the Company
shall have received an Offer Notice from a Prospective Seller, the Prospective
Seller shall not have received Notices of Acceptance indicating a desire to buy
all the Offered Shares prior to the expiration of the Offer Period and such
Prospective Seller shall not have sold the remaining Offered Shares before the
expiration of the period specified in subclause (d)(ii)(C)(1) above, then such
Prospective Seller shall not give another Offer Notice for a period of one year
from the day the Offer Notice was delivered.

            (f) Anything in this Section 5.04 or in Section 5.03 to the contrary
notwithstanding, the provisions of this Section 5.04 shall not be applicable to
any Sale or Encumbrance described in clause (i), (iii) or (iv) of Section
5.03(a).

            SECTION 5.05. Right to Participate in Certain Dispositions. (a) (i)
If, at any time during the Restricted Period, a Prospective Seller shall receive
an Offer from a Third Party or Parties, and shall propose to sell Common Stock
representing 25% or more of the Company's then outstanding Voting Interests, the
Prospective Seller shall provide the Offer Notice defined in Section 5.04 to the
Company and each of the Other Securityholders. Each of the Other Securityholders
shall have the right and option, for a period of 30 days concurrent with the
Offer Period specified in Section 5.04, to sell, pursuant to the Offer, up to
the same percentage of Voting Interests held or Beneficially Owned by it as the
Prospective Seller proposes to sell; provided that such right shall vest only
(i) if less than all the Offered Shares are sold to the Company, Other
Securityholders and Priceline pursuant to Section 5.04 and the Prospective
Seller consummates a Sale to the Third Party who made the Offer or an Affiliate
thereof or (ii) the Prospective Seller receives Notices of Election which, in
the aggregate, represent offers to buy all the Offered Shares and all the Shares
tendered by Other Securityholders pursuant to this Section 5.05. Each Other
Securityholder desiring to exercise such right shall, prior to the expiration of
the Offer Period, provide the Prospective Seller with a Notice of Election

                                       21
<PAGE>

specifying the number of Shares which such Other Securityholder has an interest
in selling pursuant to the Offer, and shall deliver to the Prospective Seller
(A) the certificate or certificates evidencing the Shares to be sold or
otherwise disposed of pursuant to such Offer by such Other Securityholder duly
endorsed in blank or accompanied by written instruments of transfer in form
satisfactory to the Prospective Seller executed by such Other Securityholder and
(B) an instrument of assignment reasonably satisfactory to the Prospective
Seller assigning, as of the consummation of the sale or other disposition to the
Third Party, all such Other Securityholder's rights under this Agreement with
respect to the Shares to be sold, and the instrument of assignment shall
constitute an irrevocable election by such Other Securityholder to authorize and
permit the Prospective Seller to sell such Shares, on behalf of such Other
Securityholder, pursuant to the Offer and in accordance herewith.

            (ii) If the Third Party making the Offer is unwilling to buy all the
Offered Shares plus all the Shares tendered by Other Securityholders in their
Notices of Election, then the Prospective Seller and each Other Securityholder
who wishes to sell shall be entitled to sell a number of Shares equal to (x) the
number of Shares the Third Party offeror is willing to buy (which shall not be
less than the number of Offered Shares), multiplied by (y) a fraction, the
numerator of which is the number of Voting Interests Beneficially Owned by such
Other Securityholder and the denominator of which is the total number of Voting
Interests Beneficially Owned by all Other Securityholders who wish to sell
Shares pursuant to the Offer. If any Other Securityholder wishes to sell less
than all the Shares he is entitled to sell in accordance with the preceding
sentence, the Shares he declines to sell shall be allocated among the
Prospective Seller and the Other Securityholders who wish to sell additional
Shares according to the same formula, mutatis mutandis. The Prospective Seller
shall not effect the Sale of any Shares pursuant to the Offer unless all the
Offered Shares and all of the Shares tendered to the Prospective Seller and
entitled to be sold pursuant to this Section 5.05 are simultaneously sold.

            (iii) As promptly as practicable after the consummation of any Sale
or other disposition of Shares to the Third Party pursuant to this Section 5.05,
the Prospective Seller shall remit to each of the Other Securityholders the
total sales price of the Shares of such Other Securityholders sold pursuant
thereto and return all certificates evidencing the unsold Shares that such Other
Securityholders delivered for Sale pursuant to this Section 5.05 and such Other
Securityholders' related instruments of assignment.

            (iv) If at the end of the Offer Period any Other Securityholder
shall not have given a Notice of Election indicating an interest in selling all
of the Shares such Other Securityholder would have been entitled to sell in
accordance with subparagraphs (a)(i) and (a)(ii) above (and delivered all other
required documents with respect thereto), such Other Securityholder shall be
deemed to have waived all its rights under this Section 5.05 with respect to the
Sale pursuant to the Offer of such Shares.

                                       22
<PAGE>

            (v) If at any time the Prospective Seller abandons the proposed Sale
pursuant to the Offer, or the Prospective Seller has not completed the Sale
pursuant to this Section 5.05 of the Offered Shares and the Shares which Other
Securityholders shall have tendered for Sale pursuant to this Section 5.05
within 30 days following expiration of the Offer Period, the Prospective Seller
shall promptly return to such Other Securityholders all certificates evidencing
the unsold Shares that such Other Securityholders delivered for Sale and such
Other Securityholders' related instruments of assignment.

            (vi) Except as expressly provided in this Section 5.05, no
Prospective Seller shall have any obligation to any Other Securityholder with
respect to the Sale or other disposition of any Shares owned by such Other
Securityholder in connection with this Section 5.05. Anything herein to the
contrary notwithstanding and irrespective of whether any Notice of Election
shall have been given, no Prospective Seller shall have any obligation to any
Other Securityholder to sell or otherwise dispose of any Offered Shares pursuant
to this Section 5.05 as a result of any decision by such Prospective Seller not
to accept or consummate any Offer or Sale or other disposition with respect to
the Offered Shares (it being understood that any and all such decisions shall be
made by such Prospective Seller in its sole discretion). No Other Securityholder
shall be entitled to sell or otherwise dispose of Shares directly to any Third
Party pursuant to an Offer (it being understood that all such Sales and other
dispositions shall be made only on the terms and pursuant to the procedures set
forth in this Article V).

            (b) Anything in this Section 5.05 or in Section 5.03 to the contrary
notwithstanding, the provisions of this Section 5.05 shall not be applicable to
any transfer described in clause (i), (iii) or (iv) of Section 5.03(a). Nothing
in this Section 5.05 shall affect any of the rights or obligations of any of the
Securityholders under any other provision of this Agreement.

            SECTION 5.06. Transferees to Execute Agreement. Each Securityholder
agrees that it will not, during the Restricted Period, directly or indirectly,
make any Sale of, or create, incur or assume any Encumbrance with respect to,
any Shares Beneficially Owned by such Securityholder unless prior to the
consummation of any such Sale or the creation, incurrence or assumption of such
Encumbrance, the Person to whom such Sale is proposed to be made or the Person
in whose favor such Encumbrance is proposed to be created, incurred or assumed
(a "Prospective Transferee") (i) executes and delivers this Agreement to the
Company and each Securityholder, and (ii) unless such Prospective Transferee is
a recognized institutional investor, delivers to the Company an opinion of
counsel, satisfactory in form and substance to the Company, to the effect that
the execution of this Agreement by such Prospective Transferee makes this
Agreement a legal, valid and binding obligation of such Prospective Transferee
enforceable against such Prospective Transferee in accordance with its terms.
Upon the execution and delivery by such Prospective Transferee of this Agreement
and, if required, the delivery of the opinion of counsel referred to in clause
(ii) of the preceding sentence, such Prospective Transferee shall be deemed a
"Securityholder" for purposes of this Agreement and

                                       23
<PAGE>

shall have the rights and be subject to the obligations of a Securityholder
under this Agreement, in each case with respect to the Shares Beneficially Owned
by such Prospective Transferee or in respect of which such Encumbrance shall
have been created, incurred or assumed.

            SECTION 5.07. Improper Sale or Encumbrance. Any attempt not in
compliance with this Agreement to make any Sale of, or create, incur or assume
any Encumbrance with respect to, any Shares shall be null and void and of no
force and effect, the purported transferee shall have no rights or privileges in
or with respect to the Company, and the Company shall not give any effect in the
Company's stock records to such attempted Sale or Encumbrance.

                                   ARTICLE VI

                               REGISTRATION RIGHTS

            SECTION 6.01. Incidental Registration. (a) If the Company at any
time proposes to register any Shares under the Securities Act for Sale in a
public offering, whether or not for its own account, on a form and in a manner
that would permit registration of Registrable Securities under the Securities
Act for Sale in such public offering, it shall each such time give prompt
written notice to all holders of Registrable Securities of its intention to do
so, specifying the form and manner and the other relevant facts involved in such
proposed registration (including, without limitation, the identity of the
managing underwriter, if applicable). Upon the written request of any such
holder of Registrable Securities delivered to the Company within 30 days after
such notice shall have been given to such holder (which request shall specify
the Registrable Securities intended to be disposed of by such holder and the
intended method of disposition thereof), the Company shall use its reasonable
best efforts to include in the registration statement relating to such public
offering all Registrable Securities that the Company has been so requested to
register by the holders of Registrable Securities, to the extent requisite to
permit the Sale of the Registrable Securities to be so registered in such public
offering; provided that:

            (i) no holder of Registrable Securities shall be entitled to
      register or sell Shares in the Company's Initial Public Offering;

            (ii) if, at any time after giving such written notice of its
      intention to register any of such Shares proposed to be registered by the
      Company and prior to the effective date of the registration statement
      filed in connection with such registration, the Company shall determine
      for any reason not to register such Shares, the Company may, at its
      election, give written notice of such determination to each holder of
      Registrable Securities that has requested to register Registrable
      Securities and thereupon the Company shall be relieved of its obligation
      to register any Registrable Securities in

                                       24
<PAGE>

      connection with such registration (but not from its obligation to pay the
      Registration Expenses in connection therewith to the extent provided in
      Section 6.01(b));

            (iii) if the proposed registration relates to an underwritten public
      offering and the managing underwriter or underwriters of such public
      offering shall advise the Company that, in its judgment, the number of
      Shares proposed to be included in such public offering should be limited
      because the inclusion of Registrable Securities is likely to materially
      and adversely affect the success of such public offering, then the Company
      shall promptly advise each such holder of Registrable Securities thereof
      and may require, by written notice to each such holder accompanying such
      advice, that, to the extent necessary to meet such limitation, all holders
      of Registrable Securities proposing to sell Shares in such public offering
      shall share pro rata in the number of Shares to be excluded from such
      offering, such sharing to be based on the respective numbers of
      Registrable Securities as to which registration has been requested by such
      holders; provided that all Registrable Securities that Priceline proposes
      to sell shall be excluded from such public offering before the Registrable
      Securities of any other party hereto; and provided further that the
      Company shall in no event be required to exclude Shares that it proposes
      to sell in such public offering; and

            (iv) the Company shall not be obligated to effect any registration
      of Registrable Securities under this Section 6.01 that is incidental to
      the registration of any of its Shares or other securities in connection
      with any merger, acquisition, exchange offer, dividend reinvestment plan
      or stock option or other employee benefit plan.

            (b) The Company shall pay all Registration Expenses in connection
with each registration of Registrable Securities effected by it pursuant to this
Section 6.01.

            SECTION 6.02. Registration on Request. (a) After the third
anniversary of the Closing, upon the written request of a Securityholder or
group of Securityholders (not including Priceline or Walker Digital) holding not
less than 25% of the then outstanding Shares (excluding any Warrant Shares
outstanding, whether held by Priceline or any transferee of Priceline),
requesting the Company to make an Initial Public Offering pursuant to a firm
commitment underwriting with a nationally recognized investment bank as lead
underwriter, the Company shall promptly give written notice of such request to
all Securityholders, and thereupon shall, as expeditiously as possible, use its
reasonable best efforts to register its Shares of Common Stock under the
Securities Act or, if so requested, register such Shares for listing on a
foreign securities exchange, and, in both cases, take such other actions as
shall be necessary to complete the Company's Initial Public Offering in
accordance with such request; provided that:

            (i) no holder of Registrable Securities shall be entitled to
      register or sell Shares in the Initial Public Offering;

                                       25
<PAGE>

            (ii) if, with respect to such Initial Public Offering, the managing
      underwriter, the Commission, the Securities Act or the rules and
      regulations thereunder, any other applicable laws, domestic or foreign, or
      the form on which any registration statement or similar document is to be
      filed, would require the conduct of an audit other than the regular audit
      conducted by the Company at the end of its fiscal year, the filing may be
      delayed until the completion of such regular audit (unless the party or
      parties requesting the Initial Public Offering agree to pay the expenses
      of the Company in connection with such an audit other than the regular
      audit); and

            (iii) if the Company, in its sole discretion, determines that the
      filing of a registration statement or commencement of an Initial Public
      Offering in the near future pursuant to this paragraph (a) would interfere
      with any financing, acquisition, corporate reorganization or other similar
      transaction involving the Company or any Subsidiary or that such
      registration or Initial Public Offering would require disclosure of
      non-public information that the Company deems advisable not to disclose,
      then the Company's obligation to file a registration statement or commence
      an Initial Public Offering shall be deferred for a period not to exceed 90
      days; provided that the Company shall not obtain such a deferral more than
      once in any twelve-month period.

            (b) If the Company has any class of securities registered under
Section 12 or 15(d) of the Exchange Act, upon the written request of Priceline,
or of a Securityholder or group of Securityholders holding not less than 25% of
the then outstanding Shares (excluding any Warrant Shares outstanding, whether
held by Priceline or any transferee of Priceline), requesting that the Company
effect the registration under the Securities Act of all or part of the
Registrable Securities held by such Securityholder or group of Securityholders
and specifying the intended method of disposition thereof, the Company shall
promptly give written notice of such requested registration to all other holders
of Registrable Securities, and thereupon shall, as expeditiously as possible,
use its reasonable best efforts to effect the registration under the Securities
Act of:

            (i) the Registrable Securities which the Company has been so
      requested to register by such Securityholder or Securityholders; and

            (ii) all other Registrable Securities that the Company has been
      requested to register by the holders of Registrable Securities by written
      request delivered to the Company within 30 days after the giving of such
      written notice by the Company (which request shall specify the intended
      method of disposition of such Registrable Securities);

provided that:

            (A) the Company shall be obligated to fulfill only two such
      registration requests by Priceline and one such registration request by
      each other holder of Registrable Securities (and for purposes of this
      clause (A), each holder of Registrable Securities

                                       26
<PAGE>

      whose Registrable Securities form part of a block as to which registration
      has been requested pursuant to this subsection (b) shall be deemed to have
      used its right to one registration request);

            (B) the Company shall not be obligated to file a registration
      statement relating to any registration request under this Section 6.02(b)
      within a period of nine months after the effective date of any other
      registration statement relating to any registration request under this
      Section 6.02(b) which was not effected on Form S-3 (or any successor or
      similar short-form registration statement) or relating to any registration
      effected under Section 6.01;

            (C) if, with respect to such registration statement, the managing
      underwriter, the Commission, the Securities Act or the rules and
      regulations thereunder, or the form on which the registration statement is
      to be filed, would require the conduct of an audit other than the regular
      audit conducted by the Company at the end of its fiscal year, the filing
      may be delayed until the completion of such regular audit (unless the
      holders of the Registrable Securities to be registered agree to pay the
      reasonable expenses of the Company in connection with such an audit other
      than the regular audit); and

            (D) if the Company, in its sole discretion, determines that the
      filing of a registration statement in the near future pursuant to this
      paragraph (b) would interfere with any financing, acquisition, corporate
      reorganization or other similar transaction involving the Company or any
      Subsidiary or that such registration would require disclosure of
      non-public information that the Company deems advisable not to disclose,
      then the Company's obligation to file a registration statement shall be
      deferred for a period not to exceed 90 days; provided that the Company
      shall not obtain such a deferral more than once in any twelve-month
      period.

            (c) If any registration requested pursuant to paragraph (b) which is
proposed by the Company to be effected by the filing of a registration statement
on Form S-3 (or any successor or similar short-form registration statement)
shall be in connection with an underwritten public offering, and if the managing
underwriter or underwriters shall advise the Company in writing that, in its
opinion, the use of another form of registration statement is of material
importance to the success of such proposed offering, then such registration
shall be effected on such other form.

            (d) An Initial Public Offering requested pursuant to paragraph (a)
shall be deemed to have been fulfilled when sufficient Shares have been sold to
meet the definition of Initial Public Offering hereunder and the Company's
Common Stock is trading on a major domestic or foreign securities exchange or
automated securities quotation system. A registration requested pursuant to
paragraph (b) shall be deemed to have been effected when the registration
statement pertaining thereto has become effective; provided that if, prior to
the earlier of the

                                       27
<PAGE>

completion of the distribution thereunder and 90 days after it has become
effective, the offering of Registrable Securities pursuant to such registration
is interfered with by any stop order, injunction or other order or requirement
of the Commission or other governmental agency or court, such registration will
be deemed not to have been effected, unless such order or requirement is
subsequently lifted and either the distribution is completed or 90 days from the
date of initial effectiveness (not counting the period during which such order
or requirement was in effect and interfered with the offering) expire.

            (e) If a requested Initial Public Offering or registration pursuant
to paragraph (b) involves an underwritten offering, the Company shall have the
right to select in good faith the investment banker or bankers and managers to
administer the offering, provided that such investment banker or bankers and
managers shall be satisfactory to (i) holders of a majority of the Shares, in
the case of paragraph (a) above, or (ii) holders of a majority of the
Registrable Securities which the Company has been requested to register, in the
case of paragraph (b) above.

            (f) If a requested registration pursuant to paragraph (b) involves
an underwritten offering and the managing underwriter or underwriters advise the
Company that, in their opinion, the number of securities requested to be
included in such registration (including securities of the Company which are not
Registrable Securities) exceeds the number which can be sold in such offering,
the Company shall include in such registration only the Registrable Securities
requested to be included in such registration pursuant to such paragraph (b). In
the event that the number of Registrable Securities requested to be included in
such registration exceeds the number which, in the opinion of such managing
underwriter or underwriters, can be sold, the number of such Registrable
Securities to be included in such registration shall be allocated pro rata among
the holders requesting registration pursuant to such paragraph (b) on the basis
of the relative number of Registrable Securities then requested for registration
by each such holder; provided that all Registrable Securities that Priceline
proposes to sell shall be excluded from such public offering before the
Registrable Securities of any other party hereto; and provided further that the
Company shall in no event be required to exclude Shares that it proposes to sell
in such public offering.

            SECTION 6.03. Registration Procedures. (a) If and whenever the
Company is required to use its reasonable best efforts to effect the
registration of any Registrable Securities under the Securities Act for Sale in
a public offering as provided in Section 6.01 or 6.02(b), the Company shall as
expeditiously as is reasonably practicable:

            (i) prepare and file with the Commission on any appropriate form a
      registration statement with respect to such Registrable Securities and use
      its reasonable best efforts to cause such registration statement to become
      effective;

                                       28
<PAGE>

            (ii) prepare and file with the Commission such amendments (including
      post-effective amendments) and supplements to such registration statement
      and the prospectus used in connection therewith as may be necessary to
      keep such registration statement effective and to comply with the
      provisions of the Securities Act with respect to the disposition of all
      Registrable Securities and other securities covered by such registration
      statement until the earlier of (A) such time as all such Registrable
      Securities and other securities have been disposed of in accordance with
      the intended methods of disposition by the seller or sellers thereof set
      forth in such registration statement and (B) the expiration of 90 days
      from the date such registration statement first becomes effective;

            (iii) furnish to each seller of such Registrable Securities such
      number of conformed copies of such registration statement and of each such
      amendment and supplement thereto (in each case including all exhibits),
      such number of copies of the prospectus included in such registration
      statement (including each preliminary prospectus and any summary
      prospectus), in conformity with the requirements of the Securities Act,
      such documents incorporated by reference in such registration statement or
      prospectus, and such other documents, as such seller may reasonably
      request in order to facilitate the sale or disposition of such Registrable
      Securities;

            (iv) use its reasonable best efforts to register or qualify all
      Registrable Securities and other securities covered by such registration
      statement under such other securities or "blue sky" laws of such
      jurisdictions as each seller shall reasonably request, and do any and all
      other acts and things that may be necessary to enable such seller to
      consummate the disposition in such jurisdictions of its Registrable
      Securities covered by such registration statement, except that the Company
      shall not for any such purpose be required to qualify generally to do
      business as a foreign corporation in any jurisdiction wherein it is not so
      qualified, or to subject itself to taxation in respect of doing business
      in any such jurisdiction, or to consent to general service of process in
      any such jurisdiction;

            (v) enter into such customary agreements (including an underwriting
      agreement in customary form), which may include indemnification provisions
      in favor of underwriters and other Persons in addition to, or in
      substitution for the provisions of Section 6.05 hereof, and take such
      other actions as sellers of a majority of shares of such Registrable
      Securities or the underwriters, if any, reasonably request in order to
      expedite or facilitate the disposition of such Registrable Securities;

            (vi) furnish to each seller of Registrable Securities a copy of (A)
      any opinion of counsel for the Company, dated the date of the closing
      under the underwriting agreement with respect to such Public Offering, in
      customary form and in form and scope reasonably satisfactory to the
      underwriter and its counsel, and (B) a "cold comfort" letter signed by the
      independent public accountants in customary form and covering matters of

                                       29
<PAGE>

      the type customarily covered by "cold comfort" letters and otherwise in
      such form and scope as the seller of such Registrable Securities shall
      reasonably request (provided that Registrable Securities constitute at
      least 25% of the securities covered by such registration statement, unless
      such a "cold comfort" letter or letters are provided to the Company or
      other selling holders or any underwriter in connection with such
      registration);

            (vii) immediately notify each seller of Registrable Securities
      covered by such registration statement at any time when a prospectus
      relating thereto is required to be delivered under the Securities Act, of
      the happening of any event as a result of which the prospectus included in
      such registration statement, as then in effect, includes an untrue
      statement of a material fact or omits to state any material fact required
      to be stated therein or necessary to make the statements therein not
      misleading in the light of the circumstances then existing or if it is
      necessary to amend or supplement such prospectus to comply with law, and
      at the request of any such seller prepare and furnish to such seller a
      reasonable number of copies of a supplement to or an amendment of such
      prospectus as may be necessary so that, as thereafter delivered to the
      purchasers of such Registrable Securities or other securities, such
      prospectus shall not include an untrue statement of a material fact or
      omit to state a material fact required to be stated therein or necessary
      to make the statements therein not misleading in the light of the
      circumstances then existing and shall otherwise comply in all material
      respects with law;

            (viii) otherwise use its reasonable best efforts to comply with all
      applicable rules and regulations of the Commission, and make available to
      its security holders, as soon as reasonably practicable, an earnings
      statement which shall satisfy the provisions of Section 11(a) of the
      Securities Act and the rules and regulations thereunder;

            (ix) use its reasonable best efforts to list such Shares on each
      securities exchange or quotation system on which Shares are then listed or
      quoted, if such Shares are not already so listed or quoted and if such
      listing is then permitted under the rules of such exchange or quotation
      system, and provide a transfer agent and registrar for such Registrable
      Securities not later than the effective date of such registration
      statement;

            (x) cooperate with the holders of Registrable Securities covered by
      the registration statement and the managing underwriter or agent, if any,
      to facilitate the timely preparation and delivery of certificates (not
      bearing any restrictive legends) representing securities to be sold under
      the registration statement, and enable such securities to be in such
      denominations and registered in such names as the managing underwriter or
      agent, if any, or such holders may request;

            (xi) notify counsel for the holders of Registrable Securities
      included in such registration statement and the managing underwriter or
      agent, immediately, and confirm

                                       30

      the notice in writing (A) when the registration statement, or any
      post-effective amendment to the registration statement, shall have become
      effective, or any supplement to the prospectus or any amendment prospectus
      shall have been filed, (B) of the receipt of any comments from the
      Commission, (C) of any request of the Commission to amend the registration
      statement or amend or supplement the prospectus or for additional
      information, and (D) of the issuance by the Commission of any stop order
      suspending the effectiveness of the registration statement or of any order
      preventing or suspending the use of any preliminary prospectus, or of the
      suspension of the qualification of the registration statement for offering
      or sale in any jurisdiction, or of the institution or threatening of any
      proceedings for any of such purposes;

            (xii) use its reasonable best efforts to prevent the issuance of any
      stop order suspending the effectiveness of the registration statement or
      of any order preventing or suspending the use of any preliminary
      prospectus and, if any such order is issued, to obtain the withdrawal of
      any such order at the earliest possible moment;

            (xiii) if requested by the managing underwriter or underwriters,
      promptly incorporate in a prospectus supplement or post-effective
      amendment such information as the managing underwriter or underwriters or
      agent or such holder reasonably requests to be included therein,
      including, without limitation, with respect to the number of Registrable
      Securities being sold by such holder to such underwriter or underwriters
      or agent, the purchase price being paid therefor by such underwriter or
      underwriters or agent and with respect to any other terms of the
      underwritten offering of the Registrable Securities to be sold in such
      offering; and make all required filings of such prospectus supplement or
      post-effective amendment as soon as practicable after being notified of
      the matters incorporated in such prospectus supplement or post-effective
      amendment;

            (xiv) cooperate with each seller of Registrable Securities and each
      underwriter or agent participating in the disposition of such Registrable
      Securities and their respective counsel in connection with any filings
      required to be made with the National Association of Securities Dealers,
      Inc.; and

            (xv) issue to any underwriter to which any holder of Registrable
      Securities may sell such Registrable Securities in connection with any
      such registration (and to any direct or indirect transferee of any such
      underwriter) certificates evidencing Shares without the legends described
      in Section 5.02(a).

The Company may require each seller of Registrable Securities as to which any
registration is being effected to furnish the Company with such information
regarding such seller and the distribution of such Registrable Securities as the
Company may from time to time reasonably request in writing and as shall be
required by law or by the Commission in connection therewith.

                                       31

            (b) Each holder of Registrable Securities agrees, if so required by
the managing underwriter or underwriters of an underwritten public offering of
Shares, not to effect any sale or distribution of Registrable Securities (other
than as part of a public offering other than the Initial Public Offering) during
the seven days prior to and 180 days after the effective date of the
registration statement with respect to such underwritten public offering;
provided that this Section 6.03(b) shall be applicable to the holders of
Registrable Securities only if all executive officers and directors and all
stockholders holding more than five percent (5%) of the then outstanding Common
Stock are subject to a similar restriction.

            Notwithstanding anything herein or in the Ancillary Agreements to
the contrary, Goldman Sachs and it Affiliates shall not be restricted from
engaging in any brokerage, investment advisory, financial advisory, anti-raid
advisory, merger advisory, financing, asset management, trading, market making,
arbitrage and other similar activities conducted in the ordinary course of its
or its Affiliates' business.

            (c) The Company agrees, if so required by the managing underwriter
or underwriters in connection with such public offering of Registrable
Securities pursuant to Section 6.01 or Section 6.02, not to effect any public
sale or distribution of any of its equity securities or securities convertible
into or exchangeable or exercisable for any of such equity securities during the
seven days prior to and the 180 days after the effective date of any
registration statement with respect to such public offering, except as part of
such public offering or except in connection with a stock option plan, stock
purchase plan, savings or similar plan, or an acquisition, merger or exchange
offer.

            (d) It is understood that, in any public offering of Registrable
Securities, in addition to the Shares (the "Initial Shares") the underwriters
have committed to purchase, the underwriting agreement may grant the
underwriters an option to purchase a number of additional shares (the "Option
Shares") equal to up to 15% of the initial Shares (or such other maximum amount
as the National Association of Securities Dealers, Inc. may then permit), solely
to cover over-allotments. Shares proposed to be sold by the Company and the
requesting holders shall be allocated between Initial Shares and Option Shares
as agreed or, in the absence of agreement, in the same manner as the Initial
Shares.

            SECTION 6.04. Preparation; Reasonable Investigation. In connection
with the preparation and filing of each registration statement registering
Registrable Securities under the Securities Act, the Company shall give the
holders of Registrable Securities on whose behalf such Registrable Securities
are to be so registered and their underwriters, if any, and their respective
counsel, accountants and other agents, upon reasonable prior notice and
according to a schedule acceptable to the management of the Company in its sole
discretion, access to its books and records and such opportunities to discuss
the business of the Company with its officers and the independent public
accountants who have issued a report on its financial statements as shall

                                       32
<PAGE>

be necessary, in the opinion of such holders and such underwriters or their
respective counsel, to conduct a reasonable investigation within the meaning of
the Securities Act.

            SECTION 6.05. Indemnification for Liabilities Under the Securities
Laws. (a) In the event of any registration of any equity securities of the
Company under the Securities Act, the Company shall indemnify and hold harmless
the seller of any Registrable Securities covered by such registration statement,
its directors and officers, managers, general and limited partners (and
directors and officers thereof and, if such seller is a portfolio or investment
fund, its investment advisors), each other Person who participates as an
underwriter in the public offering of such securities, each officer and director
of each such underwriter, and each other Person, if any, who Controls such
seller or any such underwriter within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, against any losses, claims,
damages, liabilities and expenses, joint or several, to which such seller or any
such director or officer or participating or Controlling Person may become
subject under the Securities Act or otherwise, insofar as such losses, claims,
damages, liabilities or expenses (or actions or proceedings in respect thereof)
arise out of or are based upon (i) any untrue statement or alleged untrue
statement of any material fact contained in any registration statement under
which such securities were registered under the Securities Act, any preliminary
prospectus, final prospectus or summary prospectus included therein, or any
amendment or supplement thereto, or any document incorporated by reference
therein, or (ii) any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading; and the Company shall reimburse such seller, and each such
director, officer, manager, partner, underwriter and Controlling Person for any
legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, liability, action or
proceeding; provided that the Company shall not be liable in any such case to
the extent that any such loss, claim, damage, liability (or action or proceeding
in respect thereof) or expense arises out of or is based upon (i) an untrue
statement or alleged untrue statement or omission or alleged omission made in
such registration statement, any such preliminary prospectus, final prospectus,
summary prospectus, amendment or supplement in reliance upon and in conformity
with written information furnished to the Company for use in the preparation
thereof by such seller or underwriter, as the case may be, or (ii) an untrue
statement or alleged untrue statement or omission or alleged omission made in
any preliminary prospectus but notified to such seller and underwriter prior to
any Sale of Registrable Securities and subsequently corrected by the Company in
any final prospectus, amendment or supplement made available to such seller or
underwriter but which final prospectus, amendment or supplement was not used by
such seller or underwriter in the Sale of Registrable Securities that gave rise
to such loss, claim, damage, liability (or action or proceeding in respect
thereof) or expense. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller or any such
director, officer, underwriter or Controlling Person and shall survive the
transfer of such Shares by such seller.

            (b) The Company may require, as a condition to including any
Registrable Securities in any registration statement filed pursuant to Section
6.01 or Section 6.02, that the

                                       33
<PAGE>

Company shall have received an undertaking satisfactory to it from (i) the
prospective seller of such Registrable Securities, to indemnify and hold
harmless (in the same manner and to the same extent as set forth in Section
6.05(a), except that any such prospective seller shall not in any event be
liable for an amount in excess of the net proceeds of sale of such prospective
seller's Registrable Securities so to be sold together with any amounts payable
under Section 6.06 hereof) the Company, each such underwriter of such Shares,
each officer and director of each such underwriter and each other Person, if
any, who controls the Company or any such underwriter within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, and (ii)
each such underwriter of such Shares, to indemnify and hold harmless (in the
same manner and to the same extent as set forth in Section 6.05(a)) the Company,
each officer and director of the Company, each prospective seller, each officer
and director of each prospective seller and each other Person, if any, who
Controls the Company or any such prospective seller within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, with respect
to any statement in or omission from such registration statement, any
preliminary prospectus, final prospectus or summary prospectus included therein,
or any amendment or supplement thereto, if such statement or omission was made
in reliance upon and in conformity with written information furnished by such
prospective seller or such underwriter, as the case may be, to the Company for
use in the preparation of such registration statement, preliminary prospectus,
final prospectus, summary prospectus, amendment or supplement. Such indemnity
shall remain in full force and effect regardless of any investigation made by or
on behalf of the Company or any such director, officer or Controlling Person and
shall survive the transfer of such Shares by such seller.

            (c) Promptly after receipt by an indemnified party of notice of the
commencement of any action or proceeding (including any governmental
investigation) involving a claim referred to in Section 6.05(a) or (b), such
indemnified party shall, if a claim in respect thereof is to be made against an
indemnifying party, give written notice to the latter of the commencement of
such action; provided that the failure of any indemnified party to give notice
as provided herein shall not relieve the indemnifying party of its obligations
under the preceding provisions of this Section 6.05, except to the extent that
the indemnifying party is actually prejudiced by such failure to give notice. In
case any such action is brought against an indemnified party, unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist in respect of such claim (in
which case, the indemnifying party shall not be liable for the fees and expenses
of more than one counsel for all sellers of Registrable Securities, or more than
one counsel for the underwriters in connection with any one action or separate
but similar or related actions), the indemnifying party shall be entitled to
participate in and to assume the defense thereof, jointly with any other
indemnifying party similarly notified, to the extent that it may wish with
counsel reasonably satisfactory to such indemnified party, and after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party will not be liable to such
indemnified party for any legal or other expenses subsequently incurred by the
latter in connection with the defense thereof. No indemnifying party shall
consent to entry of any

                                       34
<PAGE>

judgment or enter into any settlement which (i) does not include as an
unconditional term thereof, the giving by the claimant or plaintiff to the
Indemnified Party of a release from all liability in respect to such claim or
litigation or (ii) includes an admission of guilt on behalf of such Indemnified
Party.

            SECTION 6.06. Contribution. (a) If the indemnification provided for
in Section 6.05 is unavailable to the indemnified parties in respect of any
losses, claims, damages or liabilities referred to therein, then each
indemnifying party shall contribute to the amounts paid or payable by such
indemnified parties as a result of such losses, claims, damages or liabilities
(i) as between the Company and the holders of Registrable Securities covered by
a registration statement, on the one hand, and the underwriters, on the other,
in such proportion as is appropriate to reflect the relative benefits received
by the Company and such holders, on the one hand, and the underwriters, on the
other, from the Public Offering of the Registrable Securities, or if such
allocation is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits but also the relative
fault of the Company and such holders, on the one hand, and of the underwriters,
on the other, in connection with the statements or omissions that resulted in
such losses, claims, damages or liabilities, as well as any other relevant
equitable considerations, and (ii) as between the Company, on the one hand, and
each holder of Registrable Securities covered by a registration statement, on
the other, in such proportion as is appropriate to reflect the relative fault of
the Company and of each such holder in connection with such statements or
omissions, as well as any other relevant equitable considerations. The relative
benefits received by the Company and such holders, on the one hand, and the
underwriters, on the other, shall be deemed to be in the same proportion as the
total proceeds from the public offering (net of underwriting discounts and
commissions but before deducting expenses) received by the Company and such
holders bear to the total underwriting discounts and commissions received by the
underwriters. The relative fault of the Company and such holders, on the one
hand, and of the underwriters, on the other, shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company and such holders or by the
underwriters. The relative fault of the Company, on the one hand, and of each
such holder, on the other, shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact
relates to information supplied by such party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

            (b) The Company and the holders of Registrable Securities agree that
it would not be just and equitable if contribution pursuant to this Section 6.06
were determined by pro rata allocation (even if the underwriters were treated as
one entity for such purpose) or by any other method of allocation that does not
take account of the equitable considerations referred to in the next preceding
paragraph. The amount paid or payable by an indemnifying party as a result of
the losses, claims, damages or liabilities referred to in the next preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses

                                       35
<PAGE>

reasonably incurred by the indemnified party in connection with investigating or
defending any such action or claim. Notwithstanding the provisions of this
Section 6.06, no underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Registrable
Securities underwritten by it and distributed to the public were offered to the
public pursuant to such public offering exceeds the amount of any damages that
such underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission, and no holder of
Registrable Securities shall be required to contribute any amount (together with
any amount payable under Section 6.05(b)) in excess of the amount by which the
net proceeds from the sale of Registrable Securities received by such holder
pursuant to such public offering exceeds the amount of any damages that such
holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation. Each Securityholder's obligation to contribute
pursuant to this Section 6.06 is several in the proportion that the proceeds of
the public offering received by such Securityholder bears to the total proceeds
of the public offering received by all the Securityholders and not joint.

                                   ARTICLE VII

                              ADDITIONAL AGREEMENTS

            SECTION 7.01. New Investors to Execute Agreement. The Company shall
not, at any time prior to its Initial Public Offering, issue any shares of
Common Stock, or resell any shares of Common Stock held in its treasury, or
issue or resell any security convertible or exchangeable into Common Stock,
other than Common Stock that is issued to Priceline upon exercise of the
Priceline Warrant and Common Stock issued to the employees of the Company upon
exercise of options granted pursuant to the Company's Omnibus Employee Equity
Plan, unless prior to the consummation of any such issuance or Sale, each Person
to whom such security is proposed to be issued or sold executes and delivers
this Agreement to the Company and each Securityholder. Upon the execution and
delivery by any Person of this Agreement, Schedule I hereto shall be revised to
include the name of such Person and such Person shall be deemed a
"Securityholder" for purposes of this Agreement and shall have the rights and be
subject to the obligations of a Securityholder as such under this Agreement.

            SECTION 7.02. Rights to Purchase New Securities. (a) In the event
that the Company proposes to issue New Securities (prior to, and other than in
connection with, an Initial Public Offering), each Securityholder shall have the
right to purchase in lieu of the Person to whom the Company proposed to issue
such New Securities, in accordance with paragraph (b) below, a number of Shares
or other New Securities which the

                                       36
<PAGE>

Company proposes to issue equal to the product of (i) the total number or amount
of Shares or other New Securities which the Company proposes to issue at such
time and (ii) a fraction, the numerator of which shall be the total number of
Voting Interests which such Securityholder holds or beneficially owns at such
time, and the denominator of which shall be the sum of (i) the total number of
Voting Interests then outstanding plus (ii) the total number of Voting Interests
Priceline is entitled to purchase on the fifth anniversary date of the Priceline
Warrant or, if earlier, upon the occurrence of an Exercise Event under the
Priceline Warrant. The rights given by the Company under this Section 7.02 shall
terminate if unexercised within 30 days after receipt of the Notice of Issuance
referred to in paragraph (b) below.

            (b) In the event that the Company proposes to undertake an issuance
of New Securities (prior to, and other than in connection with, an Initial
Public Offering), it shall give written notice (a "Notice of Issuance") of its
intention to each Securityholder, describing all material terms of the New
Securities, the price and all material terms upon which the Company proposes to
issue such New Securities. Each Securityholder shall have 30 days from the date
of the Notice of Issuance to agree to purchase all or any portion of its pro
rata share of such New Securities (as determined pursuant to paragraph (a)
above) for the same consideration, if such consideration shall consist solely of
cash, or for cash, cash equivalents or marketable securities having an
equivalent value to the consideration payable by the Person to whom the Company
proposes to issue such New Securities at the time of payment, and otherwise upon
the terms specified in the Notice of Issuance by giving written notice to the
Company, and stating therein the quantity of New Securities to be purchased by
such Securityholder.

            SECTION 7.03. Further Assurances. Each of the parties hereto shall
use reasonable efforts to take, or cause to be taken, all appropriate action,
and to do, or cause to be done, all things necessary, proper or advisable under
applicable laws to consummate and make effective the transactions contemplated
hereunder, including, without limitation, using reasonable efforts to obtain all
licenses, permits, consents, approvals, authorizations, qualifications and
orders of the competent governmental entities. Without limiting the generality
of the foregoing, the parties shall, when required in order to effect the
transactions contemplated hereunder, make all necessary filings, and thereafter
make any other required or appropriate submissions, under the HSR Act and shall
supply as promptly as practicable to the appropriate governmental entity any
additional information and documentary material that may be requested pursuant
to the HSR Act. Each of the parties shall cooperate with the other when required
in order to effect the transactions contemplated hereunder. In case at any time
after the date hereof, any further action is necessary or desirable to carry out
the purposes of this Agreement, the proper officers and directors of each of the
parties shall use their reasonable best efforts to take all such action.

            SECTION 7.04. Access to Management. In addition to the rights
granted pursuant to Article VI of the Subscription Agreement, each
Securityholder shall have the right to consult with members of the Company's
management to such degree and in such manner as shall be sufficient to meet the
needs of such Securityholders' venture capital operating company requirements
under ERISA.

                                       37
<PAGE>

            SECTION 7.05. Nominees. Notwithstanding anything herein to the
contrary, any Investor may hold its shares in nominee form through a reputable
securities depository.

            SECTION 7.06. Use of Names. Neither the Company nor any of its
Affiliates shall use the names of any Investor or any Affiliate of an Investor
in any press release, notice or other publication without the prior consent of
such Investor, which such consent shall not be unreasonably withheld; provided,
however, that each Investor acknowledges and agrees that the Company may issue a
press release upon the Closing under the Subscription Agreement stating the
total amount invested in the Company and a list of the Investors.

            SECTION 7.07. Aggregation of Shares. All shares held by The Goldman
Sachs Group, Inc. shall be aggregated with the Shares held by its Affiliates,
whether such Shares were acquired hereunder or pursuant to a transfer permitted
under Article V hereof, for the purpose of determining the availability of any
rights under this Agreement and any other applicable transaction agreement.

                                  ARTICLE VIII

                                 INDEMNIFICATION

            SECTION 8.01. Indemnification of Parties. (a) The Company shall
indemnify each Securityholder or affiliate thereof, and their respective
directors, managers, officers and employees (collectively, "Non-Company
Indemnitees") against, and hold each Non-Company Indemnitee harmless from, all
claims, suits, judgments, losses, damages, fines or costs (including reasonable
legal fees and expenses) ("Losses") arising out of or resulting from the breach
of any representation or warranty made by the Company herein or the breach of or
failure to perform any agreement or covenant made by the Company and contained
herein.

            (b) Each Securityholder shall indemnify the Company and its
directors, managers, officers and employees (collectively, the "Company
Indemnitees") and the other Non-Company Indemnitees against, and hold each
Company Indemnitee and other Non-Company Indemnitee harmless from, all Losses
resulting from or arising out of any breach of any representation or warranty
made by such party herein or the breach of or failure to perform any agreement
or covenant made by such party and contained herein.

            (c) Non-Company Indemnitees and Company Indemnitees (each, an
"Indemnified Party") shall give the party hereto from whom indemnification is
sought (the "Indemnifying Party") prompt written notice of any Losses as to
which such Indemnified Party may request indemnification hereunder. If the
Indemnifying Party acknowledges in writing its obligation to indemnify the
Indemnified Party hereunder against any such Losses, then the Indemnifying Party
shall be entitled to assume and control the defense of any claim, suit, or

                                       38
<PAGE>

demand by any third party ("Third Party Claim") at its expense and through
counsel of its choice if it gives notice of its intention to do so to the
Indemnified Party within five (5) days of the receipt of such notice from the
Indemnified Party; provided that if there exists or is reasonably likely to
exist a conflict or interest that would make it inappropriate in the judgment of
the Indemnified Party, in its sole and absolute discretion, for the same counsel
to represent both the Indemnified Party and the Indemnifying Party, then the
Indemnified Party shall be entitled to retain its own counsel, at the expense of
the Indemnifying Party. In the event the Indemnifying Party exercises the right
to undertake any such defense against any such Third Party Claim as provided
above, the Indemnified Party shall cooperate with the Indemnifying Party in such
defense and make available to the Indemnifying Party, at the Indemnifying
Party's expense, all witnesses, pertinent records, materials and information in
the Indemnified Party's possession or under the Indemnified Party's control
relating thereto as is reasonably required by the Indemnifying Party. Similarly,
in the event the Indemnified Party is, directly or indirectly, conducting the
defense against any such Third Party Claim, the Indemnifying Party shall
cooperate with the Indemnified Party in such defense and make available to the
Indemnified Party, at the Indemnified Party's expense, all such witnesses,
records, materials and information in the Indemnifying Party's possession or
under the Indemnifying Party's control relating thereto as is reasonably
required by the Indemnified Party. No such Third Party Claim may be settled by
the Indemnifying Party without the prior written consent of the Indemnified
Party.

            (d) In no event shall the Indemnifying Party be liable to an
Indemnified Party for any indirect, incidental, special, punitive, exemplary or
consequential damages arising out of or otherwise relating to this Agreement,
even if the Indemnifying Party has been advised of the possibility or likelihood
of such damages.

            SECTION 8.02. Indemnification of Directors. The Company hereby
agrees to employ its reasonable efforts to enter into an agreement with each
director on the Board no later than December 31, 1999, pursuant to which
agreement the Company shall agree to indemnify such director for expenses and
liabilities arising in connection with legal proceedings to which such director
is named as a party as a result of her or his activities as director on the
Board in accordance with the By-Laws of the Company and this Agreement.

                                   ARTICLE IX

                                  MISCELLANEOUS

            SECTION 9.01. Termination. This Agreement shall terminate only:

            (a) by virtue of a written agreement to that effect, signed by all
      parties hereto or all parties then possessing any rights hereunder;

                                       39
<PAGE>

            (b) upon the expiration of (i) all rights created hereunder and (ii)
      all statutes of limitations applicable to the enforcement of claims
      hereunder;

            (c) at any time following the exercise in full or expiration
      unexercised of the Priceline Warrant, if Securityholders holding not less
      than 50% of the aggregate outstanding Shares held by the Securityholders
      (excluding Shares held by Priceline, if any) shall vote to terminate this
      Agreement at an earlier date;

provided that no termination of this Agreement pursuant to paragraph (a), (b) or
(c) above shall affect the right of any party to recover damages or collect
indemnification for any breach of the representations, warranties or covenants
herein that occurred prior to such termination.

            SECTION 9.02. Expenses. Except as otherwise specified in this
Agreement, all costs and expenses, including, without limitation, fees and
disbursements of counsel, financial advisors and accountants, incurred in
connection with this Agreement and the transactions contemplated hereby shall be
paid by the party incurring such costs and expenses.

            SECTION 9.03. Notices. All notices, requests, claims, demands and

governmental regulation or by the requirements of any securities exchange on
which the securities of a party hereto are listed, no party to this Agreement
shall make, or cause to be made, any press release or public announcement in
