     Annual Minimum

     Rent:          Commencement Date through November 30, 1994:  $360,000 per
     -----

                    December 1, 1994 through May 31, 2000: $508,561.92 per year
                    ($42,380.16 per month/$8.54 per square foot per year);

                    June 1, 2000 through May 31, 2005: [$580,817.25] per year
                    ([$48,401.44] per month/[$9.75] per square foot per year);

                    June 1, 2005 through May 31, 2010: the lesser of (i)
                    [$639,196.83] per year ([$53,266.40] per month/[$10.73] per
                    square foot per year) and (ii) the Adjusted CPI increase;

                    June 1, 2010 through May 31, 2015: the lesser of (i)
                    [$702,937.80] ([$58,578.15] per month/[$11.80] per square
                    foot per year) and (ii) the Adjusted CPI increase;

                    First Option Period: the lesser of (i) [$774,423.00] per
                    year ([$64,535.25] per month/[$13.00] per square foot per
                    year) and (ii) the Adjusted CPI increase; and

                    Second  Option  Period: the lesser of (i) [$850,673.88]  per
                    year ([$70,889.49] per month/[$14.28] per square foot per
                    year) and (ii) the Adjusted CPI increase.

          For purposes of this subsection, the "Adjusted CPI Increase" shall be
     an amount that is determined on a cumulative basis for the five year period
     ending in the year in which the Annual Minimum Rent is to be adjusted. The
     Adjusted CPI Increase shall be calculated as follows: (a) in each year of
     the five-year period ending in the year in which the Annual Minimum Rent is
     to be adjusted, the CPI for the month of May (commencing with May 2001)
     shall be compared to the CPI for the month of May in the immediately
     preceding year; (b) the percentage change in CPI shall be multiplied by
     five and the product will be the percentage annual adjustment (which shall
     not be less than zero) (the "Annual Adjustment"); (c) the Annual Adjustment
     for each of the years in the five-year period shall be cumulated, i.e.,
     added to the prior Annual Adjustment in such five (5) year period, (the
     "Cumulative Adjustment"); and (d) the final Cumulative Adjustment shall be
     the percentage (which percentage shall be capped at 10%) by which the prior
     year's

                                       2
<PAGE>

     Annual Minimum Rent shall be increased to determine the Adjusted CPI
     Increase. It is the intent of the parties hereto that the Annual Minimum
     Rent shall adjust only on June 1, 2005 and on June 1/st/ of each of the
     five year periods thereafter as set forth above. Therefore, the Annual
     Minimum Rent on June 1/st/ of each such five year period shall continue to
     be the Annual Minimum Rent until June 1/st/ of the next five year period
     set forth above. See Exhibit B for an illustration of the calculation to
                          ---------
     determine the Adjusted CPI Increase.

     "CPI" is defined as the Consumer Price Index-United States All Items for
     All Urban Consumers (1982-1984=100) published by the Bureau of Labor
     Statistics of the Department of Labor.  If the manner in which the Consumer
     Price Index as determined by the Bureau of Labor Statistics shall be
     substantially revised, an adjustment shall be made in such revised index,
     which would produce results equivalent, as nearly as possible, to those
     which would have been obtained if the Consumer Price Index had not been so
     revised.  If the Consumer Price Index shall become unavailable to the
     public, Landlord will substitute therefor a comparable index based upon
     changes in the cost of living or purchasing power of the consumer dollar
     published by any other governmental agency, a major bank or other financial
     institution, a university or a recognized financial publication.

     In addition to the foregoing Annual Minimum Rent, Tenant shall pay to
     Landlord as additional annual rent an amount sufficient to amortize the
     amount of the Tenant Allowance (as hereinafter defined) actually
     contributed by Landlord to Tenant pursuant to the terms and provisions
     hereof, at an interest rate of ten percent (10%) over the remaining Term of
     the Lease (excluding any renewal term pursuant to the exercise of the
     Options) from the date of the last contribution with payments to be made
     monthly with payments of Annual Minimum Rent.  Following determination of
     the additional annual rent, Landlord and Tenant will enter into an
     amendment to this Lease memorializing the amount of additional annual rent.

     5.   Effective as of the date hereof, the following is added to the end of
Section 6.1 of the Lease:
-----------

     Notwithstanding the foregoing, if Tenant shall fail to give any such notice
     of exercise within the aforesaid time limit, Tenant's right to exercise its
     option shall nevertheless continue until 30 days after Landlord shall have
     given Tenant written notice of Landlord's election to terminate such option
     and Tenant may exercise its option at any time until the expiration of said
     30 day period.

     6.   Effective as of the date hereof, the following new Section 9.3 to the
                                                             -----------
Lease is hereby added following Section 9.2:
                                -----------

     Landlord covenants and agrees that it will not lease any other space in the
     Shopping Center of which the Leased Premises are a part to any person nor
     will Landlord allow any person to use any of such space for purposes of the
     general sale of sporting goods or for other purposes which directly compete
     with Tenant's use of the Leased Premises.

     7.   Effective as of the date hereof, the following new Section 10.5 to the
                                                             ------------
Lease is hereby added following Section 10.4:
                                ------------

          10.5  Notwithstanding the foregoing, in the event of a Recapture (as
     hereinafter defined), from and after the effective date of such event,
     Landlord shall be responsible for all real estate taxes and assessments
     levied against the Shopping Center, and Tenant shall be responsible to pay
     Landlord its pro rata share of all such real estate taxes and assessments.
     Tenant's pro rata share shall be determined by dividing the Leaseable Floor
     Area of the Store, after Recapture, by the Leaseable Floor Area of the
     Store prior to the Recapture.  Landlord may estimate (which estimate may be
     revised from time to time, but not more than once per year, upon thirty
     (30) days written notice to Tenant) the annual amount of such real estate
     taxes and assessments based upon [one hundred five percent (105%)] of the
     most recent tax bill for the Shopping Center or the amount required by
     Landlord's lender and Tenant shall pay to Landlord monthly on or before the
     first day of

                                       3
<PAGE>

     each month, with and as part of the minimum monthly rent, its pro rata
     share of such annual real estate taxes and assessments divided by twelve
     (12). Within thirty (30) days following delivery by Landlord of the final
     real estate tax bill for any calendar year, Tenant will pay to Landlord or
     Landlord will reimburse to Tenant, as appropriate, any overage or
     deficiency versus the estimated payments made to Landlord. Landlord will
     provide Tenant with a copy of the real estate tax bill for the Shopping
     Center not later than 30 days following the date payment of the real estate
     taxes is due each year.

     Provided that Tenant is not in default in the payment of real estate taxes
     due and payable under this Lease, then, throughout the term of this Lease,
     Landlord shall pay, or cause to be paid, all real estate taxes, assessments
     and other taxes, duties and charges in the same category imposed by any
     governmental or public authority which shall be assessed or levied against
     the Shopping Center or any part thereof or any buildings or other
     improvements thereon or any appurtenances thereto or fixtures therein or
     any tax, charge or duty which may be imposed, levied or be or become a
     charge in lieu of any such present tax, charge or duty (herein collectively
     called "taxes"). All such taxes shall be paid before they become delinquent
     and Landlord agrees to provide to Tenant receipted bills or other evidence
     of payment of such taxes from time to time as such taxes are paid.
     Provided, however, that if Tenant pays any real estate taxes directly to
     the taxing authority imposing such real estate taxes as provided in Section
     10.1, Landlord shall not have the obligations imposed under this Section
     10.5 as to any real estate taxes paid by Tenant directly to the taxing
     authority imposing such real estate taxes.

     8.   Effective as of the date hereof, the following new Section 11.6 to the
                                                             ------------
Lease is hereby added following Section 11.5:
                                ------------

          11.6  Notwithstanding the provisions of Section 11.4 to the contrary,
                                                  ------------
     in the event of a Recapture, from and after the effective date of such
     event, Landlord shall be responsible for maintaining the insurance policies
     as provided in Section 11.1 hereof and tenant shall be responsible to pay
                    ------------
     Landlord its pro rata share of all costs and expenses incurred by Landlord
     in connection therewith.  Tenant's pro rata share shall be determined by
     dividing the Leaseable Floor Area of the Store after Recapture, by the
     Leaseable Floor Area of the Store Prior to Recapture.

     9.   Effective as of the date hereof, the following new Section 12.4 to the
                                                             ------------
Lease is hereby added following Section 12.3:
                                ------------

          12.4 Landlord shall at all times during the Term keep in force a
     policy or policies of public liability insurance, or an endorsement on a
     blanket liability insurance policy or policies, against claims for personal
     injuries, death or property damage, occurring on, in or about the Shopping
     Center, with a combined single limit of not less than TWO MILLION DOLLARS
     ($2,000,000). Said policy or policies shall contain Contractual Liability
     Insurance recognizing the liability assumed in Section 23.2 hereof, shall
                                                    ------------
     name Tenant as an additional insured, shall include a cross-liability
     endorsement providing that Landlord and Tenant, although named/additional
     insured, may recover on account of the negligence of the other, and shall
     be with an insurer with a policy holder's rating of at least A and a
     financial rating of not less than VII in Best's Insurance Reports.

     10.  Effective as of the date hereof, Section 13.1 of the Lease is hereby
                                           ------------
deleted in its entirety, and inserted in lieu thereof is the following:

          13.1 Anything in this Lease to the contrary notwithstanding, Landlord
     and Tenant each hereby waives any and all rights of recovery, claim, action
     or cause of action, against the other, its agents (including partners, both
     general and limited), officers, directors, shareholders or employees, for
     any loss or damage that may occur to the Shopping Center, or any
     improvements thereto, or any property of such party thereon, by reason of
     fire, the elements, or any other cause which could be insured against under
     the terms of the All Risk Policy to be carried pursuant to Section 11.1 of
                                                                ------------
     this Lease, regardless of cause or origin, including negligence of the
     other party hereto, its agents, officers or employees and covenants that no
     insurer shall hold any right of subrogation against such other party.  This
     mutual waiver is in addition to any other waiver or release contained in

                                       4
<PAGE>

     this Lease.  Landlord and Tenant shall give written notice to their
     insurers of the provisions of this waiver and release and have their
     insurance policies endorsed, if required, to prevent invalidation of
     insurance coverage by reason of this waiver and release.

     11.  Effective as of the date hereof, Section 14.1 of the Lease is hereby
                                           ------------
deleted in its entirety, and inserted in lieu thereof is the following:

          14.1 Subject to the terms and provisions of Article 20 below, during
                                                      ----------
     the Term, Tenant agrees, at no cost or expense to Landlord, to police and
     maintain the Shopping Center in good operating condition, order and repair
     at all times, and to make all replacements and repairs to the Shopping
     Center as and when necessary, including, but without limitation, repairing
     and replacing any surface paving whenever necessary, repairing, replacing
     and maintaining landscaping in the Shopping Center, keeping the same
     properly drained and reasonably free of snow, ice, water and rubbish and in
     a neat, clean orderly and sanitary condition, providing security as
     necessary to protect the property and persons of those properly using the
     Shopping Center, maintaining suitable and adequate lighting in exterior
     portions of the Shopping Center (and keeping same lighted during, and for
     at least one-half hour after, Tenant's business hours), maintaining such
     directional signs, markers and painted lines as may from time to time be
     necessary or proper for the control of parking and traffic in the Shopping
     Center, maintaining adequate access ways connecting all parking areas with
     the public streets abutting the Shopping Center.  Notwithstanding the
     foregoing, in the event of a Recapture, from and after the effective date
     of such event, Landlord shall be responsible for maintaining the Common
     Areas and exterior portions of the Store, including but not limited to
     exterior walls, roof, canopy, and HVAC units which do not exclusively serve
     the Store, and all repairs and replacements thereof, all pursuant to this
     Section 14.1 and Tenant shall be responsible to pay Landlord its pro rata
     ------------
     share of all costs and expenses incurred by Landlord in connection
     therewith, including, without limitation, a management fee equal to ten
     percent (10%) multiplied by said costs and expenses (excluding taxes).  No
     other administrative or management fee or expense shall be allowed.
     Tenant's pro rata share shall be determined by dividing the Leaseable Floor
     Area of the Store, after Recapture, by the Leaseable Floor Area of the
     Store prior to the Recapture. Landlord may estimate (which estimate may be
     revised from time to time, upon thirty (30) days written notice to Tenant)
     the annual cost of such maintenance and Tenant shall pay to Landlord
     monthly on or before the first day of each month, with and as part of the
     minimum monthly rent, its pro rata share of such annual cost divided by
     twelve (12). Within ninety (90) days following the end of each Lease Year
     Landlord will endeavor to provide Tenant with a statement of the cost of
     maintenance of the Shopping Center pursuant to this Section 14.1, with such
                                                         ------------
     supporting materials as may be reasonably requested by Tenant. Within
     thirty (30) days of receipt of such annual statement and reasonable
     supporting materials, Tenant will pay to Landlord or Landlord will
     reimburse to Tenant, as appropriate, any overage or deficiency versus the
     estimated payments made to Landlord.

     The parties acknowledge that currently the parking lot lights are metered
     as part of Tenant's premises and Landlord reimburses Tenant for a portion
     of Tenant's electrical charges attributable thereto as determined by a
     prior electrical study.  In the event of Recapture, a new electrical study
     regarding the parking lot lights which are currently metered as part of
     Tenant's premises will be conducted.  Thereafter, Landlord shall reimburse
     Tenant for the portion of the electrical attributable to the parking lot
     lights as determined by such study not less than monthly.

     12.  Effective as of the date hereof, the following new Sections 17.4 and
                                                             -------------
17.5 to the Lease are hereby added following Section 17.3:
----                                         ------------

          17.4 Upon completion of any alterations, Tenant shall provide Landlord
     with such documents as Landlord may reasonably require (including, without
     limitation, sworn contractors statements and supporting lien waivers)
     evidencing full or partial payment for such work, and "as built" working
     drawings, if available.

          17.5 Tenant may make alterations in connection with its remodeling and
     updating

                                       5
<PAGE>

     of the Store ("Remodel Alterations"). Tenant shall cause to be prepared
     plans and specifications (the "Plans") for the Remodel Alterations and
     shall submit the Plans to Landlord for its approval. Landlord shall have
     fourteen (14) days after Tenant's submission thereof to deliver any
     objections to the Plans to Tenant or, if Tenant delivers a second notice to
     Landlord after said fourteen (14) day period (the "Reminder Notice"),
     Landlord shall be deemed to have approved the Plans. Landlord agrees not to
     unreasonably withhold or condition its approval of the Plans. In the event
     Landlord

     provides Tenant with written objections to the Plans, Tenant shall promptly
     revise the Plans and the approval process shall continue until the parties
     have reached agreement. Fifteen (15) days after Landlord's review and
     approval of the "Tenant Allowance Documents" (hereinafter defined) to be
     submitted by Tenant to Landlord after completion of portions of the Remodel
     Alterations, Landlord shall disburse to Tenant the cost of Tenant's
     improvements up to the aggregate sum of Three Hundred Thousand and
     No/100ths Dollars ($300,000)(the "Tenant Allowance"). Notwithstanding the
     foregoing, Landlord and Tenant acknowledge and agree that (i) disbursements
     of the Tenant Allowance shall be in incremental amounts of not less than
     Fifty Thousand and No/100ths Dollars ($50,000) based upon the status of
     completion of the Remodel Alterations; (ii) Tenant shall not be entitled to
     more than one request for funding of a portion of the Tenant Allowance each
     calendar month; and (iii) Landlord's obligation to fund the Tenant
     Allowance shall terminate on the earlier of the date on which the aggregate
     sum of the Tenant Allowance has been funded; or [June 1, 2003]. Tenant may
     do alterations in stages and there is no requirement that Tenant complete
     all planned alterations prior to receiving any Tenant Allowance.

     As used herein, the "Tenant Allowance Documents" shall consist of the
following:

               (i) a current dated, sworn owner's statement disclosing all of
          the contracts entered into by Tenant relating to the construction of
          the Remodel Alterations and specifying, at a minimum, the name and
          address of each party, the trade of each party, the total contract
          amount for each party, and disclosing no remaining balance to be paid
          to any party for that portion of the Remodel Alterations for which
          reimbursement is sought by Tenant;

               (ii) a sworn statement/affidavit from the Tenant's general
          contractor specifying at a minimum the names and addresses of all
          contractors, subcontractors, suppliers and materialmen supplying
          labor, service and/or materials in connection with the Remodel
          Alterations to the Store, the total contract amount for each party,
          the amounts previously paid to each party, and disclosing no remaining
          balance to be paid to any party for that portion of the Remodel
          Alterations for which reimbursement is sought by Tenant;

               (iii) original notarized partial or final lien waivers as the
          case may be from the general contractor for all lienable work done and
          materials delivered for that portion of the Remodel Alterations for
          which reimbursement is sought by Tenant;

               (iv) a certificate from Tenant's architect certifying that the
          portion of the Remodel Alterations for which reimbursement is sought
          by Tenant have been finally completed in accordance with all
          applicable provisions of the Lease and in accordance with the plans
          and specifications approved by Landlord, and no asbestos-containing
          materials have been used in the construction thereof; and

               (v) an estoppel certificate executed by Tenant in the form
          attached hereto as Exhibit A.
                             ---------

     13.  Effective as of the date hereof, Section 18.1 of the Lease is hereby
                                           ------------
deleted in its entirety, and inserted in lieu thereof is the following:

          18.1 Tenant, as well as its agents, employees and customers
     (collectively, the "Customers") shall have and hereby are granted complete,
     nonexclusive and undisturbed access to, and use of, all Common Areas.
     Landlord shall use its reasonable best efforts to

                                       6
<PAGE>

     prevent the Common Areas from being used by other than Tenant and its
     Customers, or, in the event of a Recapture, the Customers of other
     tenant(s) of the Shopping Center. Tenant shall maintain all Common Areas in
     good condition, repair and cleanliness, including ice and snow removal, and
     free of any impediments to easy and safe movement within the Common Areas,
     subject to the terms and provisions of Section 14.1 above. Should any other
                                            ------------
     tenant or its Customers use parking such that Tenant or its Customers
     regularly experience a lack of adequate parking for use in conjunction with
     the Store,

     Landlord shall designate no less than fifty (50) parking spaces in close
     proximity to the entrance of the Store for the exclusive use of Tenant and
     its Customers and shall use commercially reasonable efforts to prevent the
     use of such parking by other tenants or their Customers. Tenant shall be
     permitted from time to time to conduct special events and/or tent sales in
     the parking lot and sidewalk sales on the sidewalks of the Shopping Center.

     14.  Effective as of the date hereof, the following shall be inserted at
the end of Section 22.1 of the Lease:
           ------------

     In the event a lien is filed, the party receiving notice of such filing
     shall provide notice to the other party within fifteen (15) days and shall
     cause such lien to be discharged within thirty (30) days unless the lien is
     being contested and enforcement thereof is stayed during such contest.  If
     a party shall fail to cause such lien to be so discharged, then in addition
     to any other right or remedy which the other party may have, the other
     party may, but shall not be obligated to, discharge the same either by
     paying the amount claimed to be due or by procuring the discharge of such
     lien by deposit or by bonding proceedings, and in any such event such party
     shall be entitled, if such party so elects, to compel the prosecution of
     any action for the foreclosure of such lien by the lienor and to pay the
     amount of the judgment in favor of the lienor with interest, costs and
     allowances.  Any amount so paid and all costs and expenses (including
     reasonable counsel fees) incurred in connection therewith, together with
     interest thereon at the lesser of (i) twelve percent (12%) per annum, or
     (ii) the maximum rate permitted by law from the date of making of the
     payment or incurring of the cost or expense, shall be promptly paid upon
     demand to the party incurring such costs within fifteen (15) days of
     written demand.  If Landlord does not pay such amounts to Tenant within
     fifteen (15) days of written demand, Tenant may offset any amounts due from
     Rent next coming due.

     15.  Effective as of the date hereof, the following shall be inserted as
Section 26.1 of the Lease:
------------

     LANDLORD'S DEFAULT: If Landlord fails to pay any installment of taxes or
     assessment or any interest, principal, costs or other charges upon any
     lease, mortgage or deed of trust or other lien or encumbrance affecting the
     Store or Shopping Center and to which this Lease may be subordinate when
     any of the same become due or if Landlord fails to make any repairs or do
     any work required of Landlord by the provisions of this Lease, or in any
     other respect fails to perform any obligation under this Lease to be
     performed by Landlord, and such failure continues for 30 days after written
     notice thereof is sent by Tenant to Landlord informing Landlord of such
     failure, then Landlord shall be deemed to be in default under this Lease;
     provided, however, that if the failure set forth in Tenant's notice is such
     that it requires more than 30 days to correct, Landlord shall not be deemed
     to be in default hereunder if Landlord (i) promptly and diligently
     commences curing the failure within 30 days after written notice is sent by
     Tenant to Landlord informing Landlord of such failure, and (ii) diligently
     prosecutes the cure to completion following the expiration of the original
     30 day period set forth herein. However, if Landlord desires to contest the
     validity or correctness of any lien or encumbrance, it may do so, provided
     that it shall first furnish Tenant with a good and sufficient bond
     indemnifying Tenant against any loss, liability or damage on account
     thereof.

     16.  Effective as of the date hereof, the following shall be inserted as
Section 26.2 of the Lease:
------------

     TENANT'S REMEDIES: (a) Upon any default by Landlord, Tenant may (but this

                                       7
<PAGE>

     shall not be deemed to impose an obligation upon Tenant to do so), in
     addition to any remedies available to it at law or in equity pay such
     taxes, assessments, interest, principal, costs and other charges and cure
     such defaults on behalf of and at the expense of Landlord, and do all
     necessary work and make all necessary payments in connection therewith
     including but not limited to the payment of any fees, costs and charges of
     or in connection with any legal action which may have been brought, the
     cost of which performance, upon the proper payment thereof, together with
     all interest and penalties

     necessarily paid in connection therewith and any and all other damages
     incurred by Tenant as a result of any such default, shall be paid to Tenant
     by Landlord within 30 days after written demand, with interest thereon at
     the lesser of (i) twelve percent (12%) per annum, or (ii) the maximum rate
     then permitted by law, from the date of each expenditure and/or occurrence
     or, at the continuing option of Tenant, the same may (in whole or in part),
     with interest as aforesaid, be deducted from minimum rent and/or percentage
     rent and any other payments required by Tenant to Landlord hereunder which
     may be due or become due thereafter. Nothing herein contained shall
     preclude Tenant from proceeding to collect the amount so paid by it as
     aforesaid without waiting for rental offsets to accrue. In no event shall
     such deduction be the basis of forfeiture of this Lease nor constitute a
     default in the payment of rent unless Tenant shall fail to pay the amount
     of such deduction within thirty (30) days after Tenant's receipt of notice
     of a final adjudication that such amount is owing the Landlord. If at the
     expiration of this Lease there shall be any sums owing by Landlord to
     Tenant, this Lease may at the election of Tenant be extended and continue
     in full force and effect until the next January 31st following the date
     when the indebtedness of Landlord to Tenant shall have been fully paid.
     Tenant may exercise said right of extension by giving Landlord notice at
     least fifteen (15) days prior to the expiration of this Lease of its intent
     to so extend the term. Notwithstanding the foregoing provisions of this
     Section and regardless of whether an event of Landlord's default shall have
     occurred, such curative action by Tenant may be taken without any notice if
     the condition constitutes an emergency provided that Tenant immediately
     notifies Landlord of any such action taken. If a court finally determines
     that Tenant has improperly exercised its self-help and/or offset rights,
     Tenant shall have 30 days after receipt of notice of such final judgment to
     pay to Landlord any sums found by such court to be due from Tenant to
     Landlord before Landlord shall have the right to declare a termination of
     this Lease.

     17.  Effective as of the date hereof, Section 28.1 of the Lease is hereby
                                           ------------
deleted in its entirety, and inserted in lieu thereof is the following:

     28.1 Tenant Assignment/Subletting.
          ----------------------------

          28.1.1  Provided that Tenant is not in default under this Lease,
     Tenant shall have the right, at any time, to assign this Lease or sublet
     all or any part of the Store to any entity; provided that (i) Tenant
     continues to remain primarily liable on its obligations set forth herein;
     (ii) any such subtenant and/or assignee shall assume and be bound by all
     obligations of Tenant for payment of all amounts of rental and other sums
     and the performance of all covenants required by Tenant pursuant to this
     Lease; (iii) any such subtenant and/or assignee intends to operate the
     Shopping Center in accordance with the usage restrictions of this Lease;
     and (iv) not less than ten (10) days prior to the effective date of such
     transaction, Tenant provides Landlord with copies of the documents
     evidencing such transaction and such evidence as Landlord may reasonably
     required to establish that such transaction falls within the terms and
     provisions of this paragraph.

          28.1.2  A sale by Tenant of all or substantially all of its assets or
     all or substantially all of its stock if Tenant is a publicly traded
     corporation, a merger of Tenant with another corporation, the transfer of
     twenty-five percent (25%) or more of the stock if Tenant is not a publicly
     traded corporation, or transfer of twenty-five (25%) or more of the
     beneficial ownership interests in a non-corporate tenant shall constitute
     an assignment hereunder.

          28.1.3  Notwithstanding anything contained in this Section 28.1 to the
                                                             ------------
     contrary, thirty (30) days prior to any assignment or subletting, or
     amendment or extension to any existing assignment or subletting, Tenant
     shall notify Landlord (the "Tenant Notice"),

                                       8
<PAGE>

     provide Landlord with a copy of said assignment or subletting, and
     Landlord, within ten (10) days thereafter, shall have the right to reduce
     the square footage of the Store as to the portion of the Store to be
     assigned or sublet (a "Recapture") by delivering Tenant with written notice
     thereof (a "Recapture Notice"). In the event Landlord provides the
     Recapture Notice: (i) such reduction shall be effective as of the date set
     forth in a written notice from Landlord to Tenant which date shall in no
     event be more than thirty (30) days following the Tenant Notice; (ii)
     Tenant's minimum annual rent shall be proportionately

     reduced; and (iii) at Landlord's option, if set forth in the Recapture
     Notice, Tenant shall assign Landlord the assignment or sublet agreement. If
     Landlord does not deliver the Recapture Notice, the square footage of the
     Store shall not be reduced, Tenant shall remain liable for the entire Store
     and minimum annual rent, and Tenant shall be free to enter into said
     assignment or recapture within ten (10) days thereafter. Landlord's
     exercise or failure to exercise a Recapture shall not eliminate Tenant's
     obligation to obtain the consent of Landlord or re-notice Landlord in
     respect of any future sublettings or assignments, or amendments thereto. In
     the event of a Recapture, Tenant shall have the right to have the Store
     measured after such Recapture and thereafter, the Size of the Store as set
     forth in Section 1.3 shall be as determined by such measurement and
     Tenant's pro rata share shall be appropriately adjusted as provided in
     Sections 10.5, 11.6 and 14.1 hereof. Any measurement shall be based on the
     actual number of square feet of floor space within the exterior walls of
     all floors, measured to the center lines of all common walls, including any
     basements, and including stairs, interior elevators, escalators, air
     conditioning and other interior equipment rooms; but excluding loading
     docks and platforms, transformer vaults, utility penthouses or utility
     enclosures and any mezzanine space.

          All documents utilized by Tenant to evidence any subletting or
     assignment to which Landlord has consented shall be subject to prior
     approval by Landlord or its counsel. Tenant shall pay on demand all of
     Landlord's costs and expenses, including reasonable attorneys' fees,
     incurred in determining whether or not to consent to any requested sublease
     or Assignment and in reviewing and approving such documentation, provided,
     in no event shall Tenant be liable for costs in excess of Five Hundred and
     No/100ths Dollars ($500.00) per request.

     18.  Effective as of the date hereof, the following new Section 28.2 to the
                                                             ------------
Lease is hereby inserted following the replacement Section 28.1 set forth above:
                                                   ------------

          28.2 Landlord Assignment. Landlord shall have the right to sell,
               -------------------
     transfer or assign in whole or in part, its rights and obligations under
     this Lease and in the Store. Notwithstanding anything in this Lease to the
     contrary, any such sale, transfer or assignment shall operate to release
     Landlord from any and all subsequent liabilities under this Lease and shall
     result automatically in the purchaser or assignee assuming and agreeing to
     carry out all the covenants and obligations of Landlord herein.

     19.  Except as expressly modified by this First Amendment, the terms and
provisions of the Lease shall remain in full force and effect, and Landlord and
Tenant hereby ratify, confirm and affirm each and every term and provision
thereof.

     20.  The Lease, as amended by this First Amendment, constitutes the entire
agreement between Landlord and Tenant, supersedes any prior agreement or
understanding between Landlord and Tenant (including, without limitation, the
Extension Letter), and may not be further modified or amended in any manner
other than in a writing signed by each of Landlord and Tenant.

     21.  This First Amendment may be executed in one or more counterparts, each
of which shall be deemed an original, and all of which, when taken together,
shall constitute one and the same instrument.

     22.  This First Amendment is executed by the undersigned Land Trustee as
Landlord, not personally, but solely as Trustee in the exercise of the power and
authority conferred upon and vested in it as such Trustee. It is expressly
understood and agreed that all of the warranties,

                                       9
<PAGE>

indemnities, representations, covenants, undertakings and agreements herein made
on the part of the Trustee are undertaken by it solely in its capacity as
Trustee, and not personally. No personal liability or personal responsibility is
assumed by or shall at any time be asserted or enforceable against the Trustee
on account of any warranty, indemnity, representation, covenant, undertaking or
agreement of the Trustee in the Lease, as modified and amended by this First
Amendment.

     Re:  Lease dated as of September 1, 1994, as amended by that certain First
     Amendment to Lease dated as of  January 28, 2000  (as amended, the
                                     ----------------
     "Lease"), demising certain premises commonly known as 1015 East Golf Road,
     Schaumburg, Illinois (the "Premises")

Gentlemen:

     We are the Tenant under the Lease. All capitalized terms used but not
otherwise defined herein shall have the meanings ascribed thereto in the Lease.
We hereby certify, for your benefit and for the benefit of your respective
successors and assigns, that as of the date of this estoppel certificate:

     1.   The Lease is in full force and effect and, except as set forth above,
has not been assigned, supplemented, modified or amended, and there do not exist
any other agreements concerning the Shopping Center between the Landlord and us.

     2.   The term of the Lease commenced on September 1, 1994 and will expire
on May 31, 2015, subject to the exercise of the Options set forth in the Lease.

     3.   We are not in default under the Lease, and to the best of our
knowledge, (i) the Landlord is not in default under the Lease, and (ii) no state
of fact exists which with the passage of time, the giving of notice, or both,
would constitute a default by the Landlord under the Lease.

     4.   To the best of our knowledge, we have no outstanding defenses,
offsets, liens, claims or credits under the Lease against the Landlord or
against the enforcement of any provision of the Lease by the Landlord.

     5.   There is no rent concession by Landlord under the Lease which has not
yet been fully paid.

     6.   The minimum rent payable under the Lease is at the rate of $________
per month.

     7.   In addition to minimum rent, we, as Tenant, are required to pay all
          real estate taxes and assessments which are assessed, levied,
          confirmed, imposed upon, or become due and payable out of, or in
          respect of, or become a lien on the Shopping Center, or any part
          thereof or any appurtenance thereto.

     8.   We certify that Landlord has paid the sum of $_________ as a portion
of the Tenant Allowance. The remaining balance of the Tenant Allowance yet to be
funded is $__________.


                                        Very truly yours,

                                        SPORTMART, INC.
