pursuant to Section 7.

product of (x) the monthly fee established by the parties for such Service in
accordance with Section 4.1(a) or Section 4.1(b) of this Agreement, as
applicable, multiplied by (y) a fraction, the numerator of which is the number
of days in the Termination Month such Services are provided, and the denominator
of which is 30.

      5.3   Procedures for Indemnification. Any indemnification claims made
hereunder shall be made in accordance with the terms of the Assignment
Agreement.

      SECTION 6. CONFIDENTIALITY.

      Each party shall keep confidential the Schedules to this Agreement and all
information received from the other party regarding the Services, including any
information received with respect to GLC or GLC Housing, and to use such
information only for the purposes set forth in this Agreement unless otherwise
agreed to in writing by the party from which such information was received. In
the event a party is required by any court or legislative or administrative body
(by oral questions, interrogatories, requests for information or documents,
subpoena, civil investigation demand or similar process) to disclose any
confidential information provided pursuant to this Agreement, the party shall
provide the other party with prompt notice of such requirement in order to
afford the other party an opportunity to seek an appropriate protective order or
other remedy. However, if the other party is unable to obtain or does not seek
such protective order and the party required to disclose the confidential
information is, in the opinion of its counsel, legally compelled to disclose
such confidential information, disclosure of such information may be made
without liability under this Agreement. The covenants in this Section 6 shall
survive any termination of this Agreement indefinitely with respect to
information qualifying as a trade secret under applicable law and for a period
of three (3) years from the date such termination becomes effective with respect
to all other information.

      SECTION 7. TERM.

      7.1   Duration. (a) Subject to Sections 6, 7.2, 7.3 and 7.4, the term of
this Agreement shall commence on the date hereof and shall continue in full
force and effect until the earlier of (i) the expiration of the duration or term
period assigned to the Services as agreed upon between the parties from time to
time in accordance with this Agreement or (ii) two (2) years following the
closing date of the Transaction.

            (b)   Each party acknowledges that the purpose of this Agreement is
for GLC to provide the GLC Services to GLC Housing on an interim basis until GLC
Housing can perform

                                     - 5 -
<PAGE>

the GLC Services for itself, and for GLC Housing to provide the GLC Housing
Services to GLC on an interim basis until GLC can perform the GLC Housing
Services for itself. Accordingly, each of GLC and GLC Housing shall use its
commercially reasonable efforts to make or obtain such approvals, permits and
licenses and implement such systems, as shall be necessary for it to provide the
appropriate Services for itself as promptly as practicable. As GLC Housing
becomes self-sufficient or engages other sources to provide any GLC Service, GLC
Housing shall be entitled to release GLC from providing any or all of the GLC
Services hereunder by delivering a written notice thereof to GLC at least thirty
(30) days prior to the effective date of release of such GLC Service(s). At the
end of such thirty (30) day period (or such shorter period as may be agreed by
the parties), GLC shall discontinue the provision of the GLC Services specified
in such notice and any such GLC Services shall be excluded from this Agreement,
and Schedule A shall be deemed to be amended accordingly. As GLC becomes
self-sufficient or engages other sources to provide any GLC Housing Service, GLC
shall be entitled to release GLC Housing from providing any or all of the GLC
Housing Services hereunder by delivering a written notice thereof to GLC Housing
at least thirty (30) days. At the end of such thirty (30) day period (or such
shorter period as may be agreed by the parties), GLC Housing shall discontinue
the provision of the GLC Housing Services specified in such notice and any such
GLC Housing Services shall be excluded from this Agreement, and Schedule B shall
be deemed to be amended accordingly.

      7.2   Early Termination by GLC. GLC may terminate this Agreement by giving
written notice to GLC Housing if GLC Housing shall default in the performance of
any of its material obligations under, or breach any of its warranties set forth
in, this Agreement, and such default or breach shall continue and not be
remedied for a period of thirty (30) days after GLC has given written notice to
GLC Housing specifying such default or breach and requiring it to be remedied.

      7.3   Early Termination by GLC Housing. GLC Housing may terminate this
Agreement by giving written notice to GLC if GLC shall default in the
performance of any of its material obligations under, or breach any of its
warranties set forth in, this Agreement and such default or breach shall
continue and not be remedied for a period of thirty (30) days after GLC Housing
has given written notice to GLC specifying such default or breach and requiring
it to be remedied.

      7.4   Force Majeure. In the event the performance by GLC Housing or GLC of
their respective duties or obligations hereunder is interrupted or interfered
with by reason of any cause beyond its reasonable control, including fire,
storm, flood, earthquake, explosion, war, strike or labor disruption, rebellion,
insurrection, quarantine, act of God, boycott, embargo, shortage or
unavailability of supplies, riot, or governmental law, regulation or edict
(collectively, the "Force Majeure Events"), the party affected by such Force
Majeure Event shall not be deemed to be in default of this Agreement by reason
of its nonperformance due to such Force Majeure Event, but shall give prompt
written notice to the other party of the Force Majeure Event. The party affected
by the Force Majeure Event shall cooperate with the other party in obtaining, at
the other party's sole expense, an alternative source for the affected Services,
and the other party shall be released from any payment obligation to the party
affected by the Force Majeure Event with respect to such Services during the
period of such Force Majeure Event. Additionally, upon

                                     - 6 -
<PAGE>

and during the occurrence of a Force Majeure Event, at the sole option of the
party receiving the Services affected by the Force Majeure Event, the term of
this Agreement shall be tolled with respect to any Services that are not being
provided by a third party.

      7.5   Consequences on Termination. In the event this Agreement expires or
is terminated in accordance with this Section 7, then (a) all Services to be
provided will promptly cease, (b) each of GLC and GLC Housing shall promptly
return all confidential information received from the other party in connection
with this Agreement (including the return of all information received with
respect to the Services of GLC or GLC Housing, as the case may be), without
retaining a copy thereof, and (c) each of GLC and GLC Housing shall honor all
credits and make any accrued and unpaid payment to the other party as required
pursuant to the terms of this Agreement, and no rights already accrued hereunder
shall be affected.

      SECTION 8. RECORDS.

      Each of the parties shall create and, for a period of six (6) years after
the termination or expiration of this Agreement, maintain full and accurate
books in connection with the provision of the Services, and all other records
relevant to this Agreement, and upon reasonable notice from the other party
shall make available for inspection and copy by such other party's agents such
records during reasonable business hours.

      SECTION 9. DISPUTE RESOLUTION.

out of or relating to the performance, breach or interpretation of this
Agreement shall be handled in accordance with the terms of the Assignment
Agreement.

      9.2   Continuity of Service and Performance. Unless otherwise agreed
herein or in writing, the parties will continue to provide Services and honor
all other commitments under this Agreement and each Ancillary Agreement (as

resolution pursuant to the provisions of this Section 9 with respect to all
matters not subject to such dispute, controversy or claim.
