                        (b) if the Managing Member reasonably determines that an
         adjustment is necessary or appropriate to reflect the relative economic
         interests of the Members, the Gross Asset Values of all Company assets
         shall be adjusted to equal their respective gross fair market values,
         as reasonably determined by the Managing Member, as of the following
         times:

                            (i) a Capital Contribution (other than a de minimis
                  Capital Contribution) to the Company by a new or existing
                  Member as consideration for Units; and

                            (ii) the distribution by the Company to a Member of
                  more than a de minimis amount of Company property as
                  consideration for the redemption of Units; and

<PAGE>

                        (c) the Gross Asset Values of all Company assets shall
         be adjusted to equal their respective gross fair market values, as
         reasonably determined by the Managing Member, upon the liquidation of
         the Company within the meaning of Section 1.704-1(b)(2)(ii)(g) of the
         Regulations;

                        (d) the Gross Asset Values of Company assets distributed
         to any Member shall be the gross fair market values of such assets
         (taking Section 7701(g) of the Code into account) as reasonably
         determined by the Managing Member as of the date of distribution; and

                        (e) the Gross Asset Values of Company assets shall be
         increased (or decreased) to reflect any adjustments to the adjusted
         basis of such assets pursuant to Sections 734(b) or 743(b) of the Code,
         but only to the extent that such adjustments are taken into account in
         determining Capital Accounts pursuant to Section 1.704-1(b)(2)(iv)(m)
         of the Regulations (See Exhibit A); provided, however, that Gross Asset
         Values shall not be adjusted pursuant to this paragraph to the extent
         that the Managing Member reasonably determines that an adjustment
         pursuant to paragraph (b) above is necessary or appropriate in
         connection with a transaction that would otherwise result in an
         adjustment pursuant to this paragraph (e).

         At all times, Gross Asset Values shall be adjusted by any Depreciation
         taken into account with respect to the Company's assets for purposes of
         computing Net Income and Net Loss. Any adjustment to the Gross Asset
         Values of Company property shall require an adjustment to the Members'
         Capital Accounts; as for the manner in which such adjustments are
         allocated to the Capital Accounts, see paragraph (c) of the definition
         of Net Income and Net Loss in the case of adjustment by Depreciation,
         and paragraph (e) of said definition in all other cases.

                        (d) Section 1.1 of the Restated Agreement is hereby
         amended by inserting the following new defined terms in appropriate
         alphabetical order in such section:

                  "DAI" shall mean DA Retail Investments, LLC, a Delaware
         limited liability company.

                  "DAI Contribution Obligation" shall mean the obligation of DAI
         to make a Capital Contribution pursuant to Section 7.8 hereof.

                  "Exchange Act" shall mean the Securities Exchange Act of 1934,
         as amended."

                  "Exculpatory Liabilities" shall mean Company liabilities with
         respect to which both of the following conditions are met: (i) the
         creditor's right to repayment is not limited to specified assets of the
         Company (i.e., the liability constitutes a recourse obligation of the
         Company), and (ii) no Member or related person bears the economic risk
         of loss for such liability (as determined pursuant to Section 1.752-2
         of the Regulations, except that for this purpose the DAI Contribution
         Obligation shall be disregarded).

                                       3
<PAGE>

                  "Gross Asset Value Available to Pay Recourse Liabilities and
         Exculpatory Liabilities" shall be determined upon liquidation of the
         Company and shall mean the excess of (i) the aggregate Gross Asset
         Value of all Company assets (not including the DAI Contribution
         Obligation or any similar capital contribution obligation or capital
         account restoration obligation of any other Member), except that for
         this purpose Code Section 7701(g) shall not be applied in determining
         the fair market value of an asset solely because it is subject to or
         available to satisfy one or more Exculpatory Liabilities, over (ii) the
         aggregate amount of all Nonrecourse Liabilities other than Exculpatory
         Liabilities.

                  "Recourse Liabilities" shall mean Company liabilities with
         respect to which a Member or related person bears the economic risk of
         loss (as determined pursuant to Section 1.752-2 of the Regulations,
         except that for this purpose the DAI Contribution Obligation shall be
         disregarded).

                  "Securities Act" shall mean the Securities Act of 1933, as
         amended.

         3. NEW SECTION 4.8. Article IV of the Restated Agreement is hereby
amended by adding the following new section at the end thereof:

                  "4.8 ESTABLISHMENT OF SERIES C PREFERRED UNITS. A new series
         of Preferred Units designated as the "8.25% Series C Cumulative
         Preferred Units" (the "Series C Preferred Units") is hereby established
         and shall have such rights, preferences, limitations and qualifications
         as are described on Schedule C, attached hereto and by this reference
         made a part hereof (in addition to the rights, preferences, limitations
         and qualifications contained elsewhere in this Agreement, to the extent
         applicable). The maximum number of Series C Preferred Units which may
         be issued by the Company from time to time shall be 20,000."

         4. ISSUANCE OF SERIES C PREFERRED UNITS. Concurrently herewith, the
Company is issuing to DAI 20,000 Series C Preferred Units in exchange for a
Capital Contribution by DAI of $5,000,000. DAI is hereby admitted as a Member in
respect of the Series C Preferred Units issued to it, and DAI hereby agrees to
be bound by the provisions of the Restated Agreement, as the same is amended
hereby and as the same may be amended from time to time, with respect to such
Series C Preferred Units. Series C Preferred Units shall not have any relative,
participating, optional or other special rights and powers other than as set
forth in the Restated Agreement, as the same is amended hereby. Series C
Preferred Units that are redeemed or purchased by the Company shall be cancelled
and may not be reissued.

         5. AMENDMENT TO SECTION 7. Section 7 of the Restated Agreement is
hereby amended by adding the following new Section 7.8 at the end thereof:

                  "7.8 DAI CONTRIBUTION OBLIGATION. Notwithstanding any other
         provision of this Agreement (including Schedule C to this Agreement):

                  (a) Upon liquidation of the Company, in the event that the
         Gross Asset Value Available to Pay Recourse Liabilities and Exculpatory
         Liabilities is less than One Hundred Million Dollars ($100,000,000),
         DAI shall make a Capital

                                       4
<PAGE>

         Contribution to the Company of cash in immediately available funds
         equal to the least of (i) One Hundred Million Dollars ($100,000,000),
         (ii) the amount by which One Hundred Million Dollars ($100,000,000)
         exceeds the Gross Asset Value Available to Pay Recourse Liabilities and
         Exculpatory Liabilities and (iii) the aggregate amount of Recourse
         Liabilities and Exculpatory Liabilities outstanding immediately prior
         to the liquidation of the Company. Such amount shall be used to pay
         Recourse Liabilities and/or Exculpatory Liabilities or shall be
         distributed to Members other than DAI in accordance with their positive
         Capital Account balances.

                  (b) DAI shall make any Capital Contribution required to be
         made by it pursuant to this Section 7.8 no later than the later to
         occur of (i) the last day of the taxable year of the Company in which
         such liquidation occurs or (ii) 90 days after the date of such
         liquidation.

                  (c) Any Capital Contribution made by DAI pursuant to this
         Section 7.8 and the associated Capital Account credit shall be taken
         into account in allocating Net Income and Net Loss and other items of
         income, gain, loss and deduction for the taxable year of liquidation.

                  (d) DAI shall not be subrogated to the rights of any creditor
         or other person receiving the proceeds of the Capital Contribution made
         by DAI pursuant to this Section 7.8 against the Managing Member, the
         Company, another Member or any person. DAI hereby waives any right to
         reimbursement, contribution or similar right to which DAI might
         otherwise be entitled as a result of the performance of its obligations
         under this Section 7.8.

                  (e) Section 4.4 and Section 4.6 hereof shall not apply with
         respect to DAI's obligations pursuant to this Section 7.8.

                  (f) The parties intend that DAI shall bear the economic risk
         of loss within the meaning of Section 1.752-2(a) of the Regulations
         with respect to an amount of Exculpatory Liabilities and/or Recourse
         Liabilities equal to the lesser of One Hundred Million Dollars
         ($100,000,000) and the aggregate amount of Recourse Liabilities and
         Exculpatory Liabilities, and this Section 7.8 and other relevant
         provisions of this Agreement shall be interpreted and applied in a
         manner consistent therewith.

                  (g) Notwithstanding any other provision of this Agreement, at
         any time on or after June 1, 2005, DAI may terminate the DAI
         Contribution Obligation by providing twelve (12) months' prior written
         notice to the Company, provided however that the DAI Contribution
         Obligation shall not terminate if during the twelve (12) month period
         following such notice there has been:

                        (i) An entry of a decree or order for relief in respect
         of the Company by a court having jurisdiction over a substantial part
         of the Company's assets, or the appointment of a receiver, liquidator,
         assignee,

                                       5
<PAGE>

         custodian, trustee, sequestrator (or other similar official) of the
         Company or of any substantial part of its property, or ordering the
         winding up or liquidation of the Company's affairs, in an involuntary
         case under the federal bankruptcy laws, as now or hereafter
         constituted, or any other applicable federal or state bankruptcy,
         insolvency or other similar law; or

                        (ii) The commencement against the Company of an
         involuntary case under the federal bankruptcy laws, as now or hereafter
         constituted, or any other applicable federal or state bankruptcy,
         insolvency or other similar law; or

                        (iii) The commencement by the Company of a voluntary
         case under the federal bankruptcy laws, as now or hereafter
         constituted, or any other applicable federal or state bankruptcy,
         insolvency or other similar law, or the consent by it to the entry of
         an order for relief in an involuntary case under any such law or the
         consent by it to the appointment of or taking possession by a receiver,
         liquidator, assignee, custodian, trustee, sequestrator (or other
         similar official) of the Company or of any substantial part of its
         property, or the making by it of a general assignment for the benefit
         of creditors, or the failure of Company generally to pay its debts as
         such debts become due or the taking of any action in furtherance of any
         of the foregoing;

         provided that, after the passage of such 12 months, DAI shall cease to
         be liable for the DAI Contribution Obligation, at the first time, if
         any, that the appointment, case or proceeding referred to in Section
         7.8(g)(i) through (iii) above has terminated.

                  (h) As a result of the transfer of all or a portion of the
         Series C Preferred Units to a Permitted DAI Transferee pursuant to
         Section 7 of Schedule C, the transferor shall continue to be obligated
         for the entire amount of the DAI Contribution Obligation except to the
         extent that such Permitted DAI Transferee agrees to assume all or a
         portion of such transferor's obligation under the DAI Contribution
         Obligation. In the event of such a transfer to and assumption by the
         Permitted DAI Transferee, (1) the transferor and the Permitted DAI
         Transferee assuming the obligation under the DAI Contribution
         Obligation shall notify the Company that the Permitted DAI Transferee
         has assumed all or a portion of the DAI Contribution Obligation in
         connection with such transfer, and (2) this Agreement shall be amended
         to reflect such Permitted DAI Transferee's assumption of all or a
         portion of the DAI Contribution Obligation. Except to the extent that
         the Permitted DAI Transferee assumes all or a portion of the obligation
         under the DAI Contribution Obligation in accordance with this Section
         7.8(h), the transferor shall not be relieved of such obligation and
         shall continue to be obligated under the DAI Contribution Obligation
         notwithstanding the transfer and to the same extent as if the transfer
         had not occurred. Following the transfer of Series C Preferred Units to
         GGPI or the Managing Member pursuant to Section 6 of Schedule C, the
         transferor shall continue to be obligated for the entire amount

                                       6
<PAGE>

         of the DAI Contribution Obligation in accordance with its terms and
         neither GGPI nor the Managing Member shall have any liability
         therefor."

         6. NEW SCHEDULE A. Schedule A to the Restated Agreement, identifying
the Members and the number and type hereby inserted in its place and stead.

         7. NEW SCHEDULE C. Schedule C in the form attached hereto, fixing the
powers, preferences, rights, qualifications, limitations and restrictions of the
Series C Preferred Units, is hereby added to the Restated Agreement and inserted
after Schedule B thereto.

         8. OTHER PROVISIONS UNAFFECTED. Except as expressly amended hereby, the
Restated Agreement shall remain in full force and effect in accordance with its
terms.

         IN WITNESS WHEREOF, each of the parties hereto has executed this Second
Amendment (and GGPI has executed this Second Amendment solely for the purpose of
binding itself under Section 6 of Schedule C to the Restated Agreement, as
amended hereby) on the day and year first above written.

                                   SCHEDULE C
                                     TO THE
                 SECOND AMENDED AND RESTATED OPERATING AGREEMENT
                                       OF
                                  GGPLP L.L.C.

         DESIGNATION, PREFERENCES AND RIGHTS OF SERIES C PREFERRED UNITS

     1. DESIGNATION AND NUMBER; ETC. The Series C Preferred Units have been
established and shall have such rights, preferences, limitations and
qualifications as are described herein (in addition to the rights, preferences,
limitations and qualifications contained in the Agreement to the extent
applicable). The authorized number of Series C Preferred Units shall be 20,000.
Notwithstanding anything to the contrary contained herein, in the event of a
conflict between the provisions of this Schedule C and any other provision of
the Agreement, the provisions of this Schedule C shall control. Series C
Preferred Units shall not have any relative, participating, optional or other
special rights and powers other than as set forth herein.

     2. RANK OF THE SERIES C PREFERRED UNITS. The Series C Preferred Units
shall, with respect to distribution rights and rights upon liquidation,
dissolution or winding up of the Company, rank as follows:

     (a) senior to all classes or series of Common Units and all series of
Preferred Units that are not referred to in Section 2(b) or (c) of this Schedule
C (the Common Units and the Preferred Units ranking junior to the Series C
Preferred Units with respect to distribution rights and rights upon liquidation,
dissolution and winding up, collectively, "Series C Junior Units");

     (b) on parity with the Series A Preferred Units, the Series B Preferred
Units and each other series of Preferred Units that is hereafter created and
that provides by its express terms that it ranks on parity with the Series C
Preferred Units as to distribution rights and rights upon liquidation,
dissolution and winding-up of the Company (the "Series C Parity Units"); and

     (c) junior to any class or series of Preferred Units that is hereafter
established, that provides by its express terms that it ranks senior to the
Series C Preferred Units and that is approved in accordance with the provisions
of Section 3 of this Schedule C.

     3. VOTING. The Company shall not, without the affirmative vote or consent
of the holders of at least fifty-one percent (51%) of the Series C Preferred
Units outstanding at such time, (a) reclassify any Common Units into Preferred
Units ranking senior to or on parity with the Series C Preferred Units with
respect to the payment of distributions or distribution of assets upon
liquidation, dissolution or winding-up of the Company, (b) issue additional
Series C Preferred Units or (c) amend, alter or repeal this Section 3 or any
other provisions of this Schedule C or the Agreement, whether by merger,
consolidation or otherwise (a "Series C Event"), so as to negate the provisions
of clause (a) or (b) of this paragraph or materially and adversely affect any
special right, preference, privilege or voting power of the holders of the
Series C Preferred Units. Notwithstanding anything to the contrary contained
herein, each of the following shall be deemed not to materially and adversely
affect such rights, preferences, privileges or voting power and shall not
require the vote or consent of the holders of the Series C

                                      C-1
<PAGE>

Preferred Units: (A) the occurrence of any of the Series C Events set forth in
clause (c) of this paragraph so long as Series C Preferred Units remain
outstanding with the terms thereof materially unchanged (taking into account
that, upon the occurrence of such Series C Event, the Company may not be the
surviving entity) and the surviving entity is a Qualified Entity, (B) the
authorization or creation of, or the increase in the authorized or issued amount
of, the Common Units or any other series of Preferred Units, whether ranking
senior or junior to or on parity with the Series C Preferred Units (and any
amendments to the Agreement to effect such increase, creation or issuance),
provided that no such action alters the parity of the Series C Preferred Units
with the Series A Preferred Units and the Series B Preferred Units, and (C) the
liquidation, dissolution and winding-up of the Company. In addition, the Company
shall not, without the affirmative vote or consent of the holders of at least
fifty-one percent (51%) of the Series A Preferred Units, Series B Preferred
Units and Series C Preferred Units outstanding at such time (voting together as
a single class), authorize or create, or increase the authorized or issued
amount of, any class or series of Units ranking senior to the Series C Preferred
Units with respect to payments of distributions or rights upon liquidation,
dissolution or winding up of the Company (but the provisions of this sentence
only shall apply with respect to any such authorization, creation or increase if
there are Series A Preferred Units and/or Series B Preferred Units outstanding
at the time of such authorization, creation or issuance).

         For purposes of the provisions of this Section 3, each Series C
Preferred Unit (and for purposes of the last sentence of the immediately
preceding paragraph, the Series A Preferred Units and Series B Preferred Units)
shall have one (1) vote.

         Notwithstanding anything to the contrary contained herein, the
foregoing voting provisions shall not apply if, prior to the time when the act
with respect to which such vote would otherwise be required shall be effected,
all outstanding Series C Preferred Units shall have been exchanged or redeemed.

         Except as provided herein, the holders of Series C Preferred Units
shall have no voting or consent rights or other rights to participate in the
management of the Company or to receive notices of meetings.

     4. DISTRIBUTIONS.

     (a) Payment of Distributions. Each holder of Series C Preferred Units will
be entitled to receive, when, as and if declared by the Managing Member, out of
Net Operating Cash Flow and subject to the right to payment of the holders of
Preferred Units ranking senior to or on parity with the Series C Preferred
Units, cumulative preferential cash distributions per Series C Preferred Unit at
the rate per annum of 8.25% of the $250 base liquidation preference thereof (or
$5.15625 per quarter) (the "Series C Preferred Unit Distribution"). Series C
Preferred Unit Distributions with respect to any Series C Preferred Units shall
be cumulative, shall accrue from the date of the issuance of such Series C
Preferred Units and will be payable (i) quarterly when, as and if authorized and
declared by the Managing Member, in arrears, on the 15th day of January, April,
July and October of each year and (ii) in the event of an exchange or redemption
of Series C Preferred Units, on the exchange or redemption date, as applicable
(each a "Series C Preferred Unit Distribution Payment Date"), commencing on the
first of such payment dates to occur following their original date of issuance.
The amount of distribution per Series C

                                      C-2
<PAGE>

Preferred Unit accruing in each full quarterly distribution period shall be
computed by dividing the annual distribution rate by four. The amount of
distributions payable for the initial distribution period or any other period
shorter or longer than a full quarterly distribution period on the Series C
Preferred Units will be computed on the basis of twelve 30-day months and a
360-day year and the actual number of days elapsed in such a thirty (30) day
month. If any Series C Preferred Unit Distribution Payment Date is not a
Business Day, then payment of the Series C Preferred Unit Distribution to be
made on such date will be made on the next succeeding day that is a Business Day
(and without any interest or other payment in respect of such delay), except
that, if such Business Day is in the next succeeding calendar year, such payment
shall be made on the immediately preceding Business Day (without any deduction),
in each case with the same force and effect as if made on such date. Series C
Preferred Unit Distributions will be made to the holders of Series C Preferred
Units of record on the relevant record dates, which will be fifteen (15) days
prior to the relevant Series C Preferred Unit Distribution Payment Date.

     (b) Distributions Cumulative. Notwithstanding the foregoing, Series C
Preferred Unit Distributions will accrue whether or not the terms and provisions
of the Agreement or any other agreement of the Company at any time prohibit the
current payment of distributions, whether or not the Company has revenues,
whether or not there are funds legally available for the payment of such
distributions and whether or not such distributions are authorized. Accrued but
unpaid Series C Preferred Unit Distributions will accumulate as of the Series C
Preferred Unit Distribution Payment Date on which they first become payable. Any
accrued but unpaid Series C Preferred Unit Distributions that are not paid on or
prior to the date that they first become payable are hereinafter referred to as
"Series C Accumulated Preferred Unit Distributions." No interest or sum of money
in lieu of interest will be payable in respect of any Series C Accumulated
Preferred Unit Distributions. Series C Accumulated Preferred Unit Distributions
may be declared and paid at any time, without reference to any regular Series C
Preferred Unit Distribution Payment Date.

     (c) Priority as to Distributions.

          (i) So long as any Series C Preferred Units are outstanding, no
     distribution of cash or other property shall be authorized, declared, paid
     or set apart for payment on or with respect to any Series C Parity Units,
     nor shall any cash or other property be set aside for or applied to the
     purchase, redemption or other acquisition for consideration of any Series C
     Parity Units, unless, in each case, all Series C Accumulated Preferred Unit
     Distributions have been paid in full (or have been declared and a sum
     sufficient for such payment has been set aside therefor) or when Series C
     Accumulated Preferred Unit Distributions are not paid in full or a sum
     sufficient for such payment is not set apart, as aforesaid, all
     distributions declared upon Series C Preferred Units and all distributions
     declared upon any other series or class or classes of Series C Parity Units
     shall be declared ratably in proportion to the respective amounts of
     distributions accumulated and unpaid on the Series C Preferred Units and
     such Series C Parity Units.

          (ii) So long as any Series C Preferred Units are outstanding, no
     distribution of cash or other property (other than distributions paid
     solely in Series C Junior Units or options, warrants or other rights to
     subscribe for or purchase Series C Junior Units) shall

                                      C-3
<PAGE>

     be authorized, declared, paid or set apart for payment on or with respect
     to any class or series of Series C Junior Units nor shall any cash or other
     property be set aside for or applied to the purchase, redemption or other
     acquisition for consideration of any Series C Junior Units (other than
     consideration paid solely in Series C Junior Units or options, warrants or
     other rights to subscribe for or purchase Series C Junior Units) unless, in
     each case, all Series C Accumulated Preferred Unit Distributions have been
     paid in full or have been declared and a sum sufficient for payment thereof
     has been set aside therefor.

          (iii) So long as there are Series C Accumulated Preferred Unit
     Distributions (and a sum sufficient for full payment of Series C
     Accumulated Preferred Unit Distributions is not so set apart), all future
     Series C Preferred Unit Distributions shall be authorized and declared so
     that the amount of Series C Preferred Unit Distributions per Series C
     Preferred Unit shall in all cases bear to each other the same ratio that
     Series C Accumulated Preferred Unit Distributions per Series C Preferred
     Unit bear to each other.

          (iv) Notwithstanding anything to the contrary set forth herein,
     distributions on Units held by the Managing Member ranking junior to or on
     parity with the Series C Preferred Units may be made, without preserving
     the priority of distributions described in Sections 4(c)(i) and (ii) of
     this Schedule C, but only to the extent such distributions are required to
     preserve the REIT status of GGPI.

     (d) No Further Rights. Except as provided in Section 5 hereof, holders of
Series C Preferred Units shall not be entitled to any distributions, whether
payable in cash, other property or otherwise, in excess of the Series C
Preferred Unit Distributions (and any Series C Accumulated Preferred Unit
Distributions) described herein.

     5. LIQUIDATION PREFERENCE.

     (a) Payment to Holders of Series C Preferred Units. In the event of any
liquidation, dissolution or winding up of the Company, whether voluntary or
involuntary, and subject to the right to payment of holders of Preferred Units
ranking senior to or on parity with the Series C Preferred Units, before any
payment or distribution of the assets of the Company shall be made to or set
apart for the holders of Series C Junior Units, each holder of the Series C
Preferred Units shall be entitled to receive an amount equal to such holder's
Capital Account in respect of its Series C Preferred Units, but the holders of
Series C Preferred Units shall not be entitled to any further payment in respect
of their Series C Preferred Units. If, upon any such liquidation, dissolution or
winding up of the Company, the assets of the Company, or proceeds thereof,
distributable to the holders of Series C Preferred Units shall be insufficient
to pay in full the preferential amount aforesaid and liquidating payments on any
other Series C Parity Units, then such assets, or the proceeds thereof, shall be
distributed among the holders of the Series C Preferred Units and the holders of
any such other Series C Parity Units ratably in accordance with the respective
amounts that would be payable on such Series C Preferred Units and any such
other Series C Parity Units if all amounts payable thereon were paid in full.
For the purposes of this Section 5, none of a consolidation or merger of the
Company with or into one or more entities, a merger of an entity with or into
the Company, a statutory share exchange by the Company or a sale, lease or
conveyance of all or substantially all of the Company's assets shall

                                      C-4
<PAGE>

be deemed to be a liquidation, dissolution or winding up, voluntary or
involuntary, of the Company.

     (b) Payments to Holders of Series C Junior Units. Subject to the rights of
the holders of Series C Parity Units, after payment shall have been made in full
to the holders of the Series C Preferred Units as provided in this Section 5,
any series or class or classes of Series C Junior Units shall, subject to any
respective terms and provisions applying thereto, be entitled to receive any and
all assets remaining to be paid or distributed, and the holders of the Series C
Preferred Units shall not be entitled to share therein.

     6. EXCHANGE RIGHTS.

     (a) Right to Exchange.

          (i) Subject to the other terms and conditions of this Section 6,
     Series C Preferred Units will be exchangeable in whole but not in part with
     GGPI at any time on or after June 1, 2012, at the option of the holders of
     at least fifty-one percent (51%) of all outstanding Series C Preferred
     Units, for authorized but previously unissued Common Shares (and in the
     event such option is exercised, such exercise and the Series C Exchange
     Notice (as defined below) given in connection therewith shall be deemed to
     apply to all issued and outstanding Series C Preferred Units and the
     holders thereof). Each holder of Series C Preferred Units will be entitled
     to receive for each Series C Preferred Unit held by it a number of Common
     Shares equal to the quotient of the Capital Account relating to such Series
     C Preferred Unit (adjusted and booked up or down to reflect fair market
     value of Company assets through the exchange closing date) (the amount of
     such Capital Account, the "Series C Exchange Price") divided by the Current
     Per Share Market Price as of the Trading Day immediately preceding the
     exchange closing date. This exchange right is only exercisable if, at the
     time of exercise, the fair market value of the Company's assets exceeds the
     Company's liabilities (and any preferred security claims senior to the
     Series C Preferred Units) by an amount at least equal to twice the sum of
     (1) the aggregate Capital Accounts of all holders of Series C Preferred
     Units plus (2) the aggregate Capital Accounts of all holders of Series C
     Parity Units.

          (ii) Notwithstanding anything to the contrary set forth in Section
     6(a)(i) of this Schedule C, if a Series C Exchange Notice has been
     delivered to the Managing Member and GGPI, then the Managing Member or GGPI
     may at its option, within ten (10) Business Days after receipt of the
     Series C Exchange Notice, elect to purchase or cause the Company to redeem
     all or a portion of the outstanding Series C Preferred Units for cash at
     the Series C Exchange Price per Series C Preferred Unit. If such election
     by GGPI is made with respect to fewer than all of the outstanding Series C
     Preferred Units, the number of Series C Preferred Units held by each holder
     of Series C Preferred Units to be redeemed or purchased shall equal such
     holder's pro rata share (based on the percentage of the aggregate number of
     outstanding Series C Preferred Units that the total number of Series C
     Preferred Units held by such holder of Series C Preferred Units represents)
     of the aggregate number of Series C Preferred Units being redeemed or
     purchased. An election by the Managing Member or GGPI under this Section
     shall be

                                      C-5
<PAGE>

     effected by delivering notice thereof to the holders identified in the
     Series C Exchange Notice.

          (iii) If an exchange of all Series C Preferred Units pursuant to
     Section 6(a)(i) of this Schedule C would violate the provisions on
     ownership limitation of GGPI set forth in its Charter and such ownership
     limitation is not waived by GGPI, each holder of Series C Preferred Units
     shall be entitled to exchange the maximum number of Series C Preferred
     Units which would comply with the provisions on the ownership limitation of
     GGPI, and any Series C Preferred Units not so exchanged shall be purchased
     by GGPI or redeemed by the Company for cash in an amount determined in the
     manner set forth in subsection (ii) of this Section 6(a).

          (iv) If an exchange of all Series C Preferred Units pursuant to
     Section 6(a)(i) of this Schedule C is prohibited by virtue of the holder of
     the Series C Preferred Units being unable to make such customary
     representations and warranties as may be reasonably necessary for the
     Managing Member or GGPI to establish that the issuance of Common Shares
     pursuant to the exchange shall not be required to be registered under the
     Securities Act or any applicable state securities laws pursuant to Section
     6(b)(i) below, any Series C Preferred Units not so exchanged shall be
     purchased by GGPI or redeemed by the Company for cash in an amount
     determined in the manner set forth in subsection (ii) of this Section 6(a).

     (b) Procedure for Exchange and/or Redemption of Series C Preferred Units.

          (i) The exchange right only may be exercised pursuant to a written
     notice of exchange (the "Series C Exchange Notice") delivered to the
     Managing Member and GGPI by holders of Series C Preferred Units owning at
     least fifty-one percent (51%) of the outstanding Series C Preferred Units
     by fax and certified mail postage prepaid. The closing of the exchange,
     purchase and/or redemption pursuant to this Section 6 shall occur within
     fifteen (15) Business Days following the giving of the Series C Exchange
     Notice. At the closing, the exchanging holder(s) shall deliver such
     instruments of transfer and other documents as GGPI or the Managing Member
     may reasonably request, and GGPI and/or the Company shall deliver to the
     exchanging holder(s) certificates representing the Common Shares and/or the
     cash redemption and/or purchase price. Notwithstanding anything to the
     contrary contained herein, any and all Series C Preferred Units to be
     exchanged for Common Shares pursuant to this Section shall be so exchanged
     in a single transaction at one time. As a condition to the exercise of the
     rights contained in this Section 6, each holder of Series C Preferred Units
     shall make such customary representations and warranties as may be
     reasonably necessary for the Managing Member or GGPI to establish that the
     issuance of Common Shares pursuant to the exchange shall not be required to
     be registered under the Securities Act or any applicable state securities
     laws, including without limitation representations and warranties that such
     holder is an accredited investor as such term is defined in Rule 501 of
     Regulation D promulgated pursuant to the Securities Act and that such
     holder is acquiring such Common Shares for investment, solely for its own
     account and not with a view to or for the resale or distribution thereof
     (other than pursuant to the Registration Statement, as defined below);
     provided, however, that in the event a holder is unable to make such
     representations, the

                                      C-6
<PAGE>

     condition shall be deemed satisfied with respect to such holder by virtue
     of Section 6(a)(iv). Any Common Shares issued pursuant to this Section to a
     holder of Series C Preferred Units shall be delivered as shares which are
     duly authorized, validly issued, fully paid and nonassessable, free of any
     pledge, lien, encumbrance or restriction other than those provided in the
     Charter or the by-laws of GGPI, the Securities Act or relevant state
     securities or blue sky laws or created by, through or under such holder,
     and any Series C Preferred Units as to which the exchange right has been
     exercised shall be free of any pledge, lien, encumbrance or restriction
     other than those provided in the Agreement, the Securities Act and relevant
     state securities or blue sky laws (and the parties shall make
     representations and warranties to the other to such effect). Subject to the
     provisions of Section 6(c) of this Schedule C, the certificates
     representing the Common Shares issued upon exchange of the Series C
     Preferred Units shall, in addition to any legend required by the Charter,
     contain the following legend:

               THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE
               TRANSFERRED, SOLD, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE
               DISPOSED OF EXCEPT (A) PURSUANT TO AN EFFECTIVE REGISTRATION
               STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
               "ACT") OR (B) IF THE CORPORATION HAS BEEN FURNISHED WITH A
               SATISFACTORY OPINION OF COUNSEL FOR THE HOLDER OF THE SHARES
               REPRESENTED HEREBY, OR OTHER EVIDENCE SATISFACTORY TO THE
               CORPORATION, THAT SUCH TRANSFER, SALE, ASSIGNMENT, PLEDGE,
               HYPOTHECATION OR OTHER DISPOSITION IS EXEMPT FROM THE PROVISIONS
               OF SECTION 5 OF THE ACT AND THE RULES AND REGULATIONS THEREUNDER.

          (ii) In the event of an exchange of Series C Preferred Units, an
     amount equal to the Series C Accumulated Preferred Unit Distributions to
     the date of exchange on any Series C Preferred Units tendered for exchange
     shall continue to accrue on such Series C Preferred Units, which remain
     outstanding following such exchange, with the Managing Member as the holder
     of such Series C Preferred Units (GGPI having contributed the Series C
     Preferred Units to the Managing Member). Fractional Common Shares are not
     to be issued upon exchange but, in lieu thereof, the Managing Member will
     pay a cash adjustment based upon the Current Per Share Market Price as of
     the exchange closing date.

          (iii) During the thirty day period ending on the closing of any
     exchange, purchase and/or redemption pursuant to this Section 6, the
     holders of Series C Preferred Units shall not, directly or indirectly, buy
     or sell (including without limitation short-sell) any Common Shares,
     whether in the open market or in a negotiated transaction.

     (c) Registration of Common Shares.

                                       C-7
<PAGE>

          (i) As soon as practicable following the issuance of Common Shares
     pursuant to this Section 6 (but, subject to the provisions of the last
     sentence of Section 6(c)(ii) of this Schedule C, in no event more than 90
     days following such issuance), GGPI shall file a Registration Statement on
     Form S-3 or other appropriate registration form (the "Registration
     Statement") with the SEC covering the resale by the initial holders of such
     Common Shares (the "Initial Holders") and shall use its reasonable best
     efforts to cause the Registration Statement to become effective as soon as
     practicable thereafter. Following the effective date of the Registration
     Statement and until the Common Shares covered by the Registration Statement
     have been sold or are eligible for resale under Rule 144(k) promulgated
     under the Securities Act, GGPI shall keep the Registration Statement
     current, effective and available for the resale by the Initial Holders of
     the Common Shares delivered to them pursuant to this Section 6. GGPI shall
     bear all expenses relating to filing such Registration Statement and
     keeping such Registration Statement current, effective and available;
     provided, however, that GGPI shall not be responsible for any brokerage
     fees or underwriting commissions due and payable by any holder of such
     Common Shares.

          (ii) During the time period when the Registration Statement is
     required to be current, effective and available under Section 6(c)(i) of
     this Schedule C, GGPI also shall:

               (1) prepare and file with the SEC such amendments and supplements
          to the Registration Statement and the prospectus constituting a part
          thereof, as amended or supplemented (the "Prospectus"), as may be
          necessary to keep such Registration Statement effective and to comply
          with the provisions of the Securities Act with respect to the sale of
          the Common Shares covered by such Registration Statement whenever any
          Initial Holder shall desire to sell or otherwise dispose of the same
          but in no event beyond the period in which the Registration Statement
          is required to be kept in effect under Section 6(c)(i) of this
          Schedule C;

               (2) furnish to each Initial Holder, without charge, such number
          of authorized copies of the Prospectus, and any amendments or
          supplements to the Prospectus, in conformity with the requirements of
          the Securities Act, and such other documents as any Initial Holder may
          reasonably request in order to facilitate the public sale or other
          disposition of the Common Shares owned by the Initial Holders.

               (3) register or qualify the securities covered by the
          Registration Statement under state securities or blue sky laws of such
          jurisdictions as are reasonably required to effect a sale thereof and
          do any and all other acts and things which may be necessary or
          appropriate under such state securities or blue sky laws to enable the
          Initial Holders to consummate the public sale or other disposition in
          such jurisdictions of such securities;

               (4) before filing any amendments or supplements to the
          Registration Statement or the Prospectus, furnish copies of all such
          documents proposed to be filed to the Initial Holders who shall be
          afforded a reasonable

                                      C-8
<PAGE>

          opportunity to review and comment thereon; provided, however, that all
          such documents shall be subject to the approval of the Initial Holders
          insofar as they relate to information concerning the Initial Holders
          (including, without limitation, the proposed method of distribution of
          any Initial Holder's securities);

               (5) notify the Initial Holders promptly (A) when any such
          Registration Statement has become effective and when any
          post-effective amendments and supplements thereto become effective,
          (B) of any request by the SEC or any state securities authority for
          amendments and supplements to such Registration Statement and the
          Prospectus or for additional information, (C) of the issuance by the
          SEC or any state securities authority of any stop order suspending the
          effectiveness of any such Registration Statement or the initiation of
          any proceedings for the purpose, (D) if, between the effective date of
          any such Registration Statement and the sale of the Common Shares to
          which it relates, GGPI receives any notification with respect to the
          suspension of the qualification of the Common Shares or initiation of
          any proceeding for such purpose, and (E) of the happening of any event
          during the period such Registration Statement is effective which in
          the judgment of GGPI makes any statement made in the Registration
          Statement or the Prospectus untrue in any material respect or which
          requires the making of any changes in the Registration Statement or
          the Prospectus in order to make the statements therein not misleading;

               (6) use its reasonable best efforts to obtain the withdrawal of
          any order suspending the effectiveness of a Registration Statement at
          the earliest practicable time;

               (7) cooperate with each Initial Holder to facilitate the timely
          preparation and delivery of certificates representing Common Shares
          being sold, which certificates shall not bear any restrictive legends,
          provided the Common Shares evidenced thereby have been sold in a
          manner permitted by the Prospectus; and

               (8) upon the occurrence of any event contemplated by Section
          6(c)(ii)(5)(E) hereof, promptly prepare and file a supplement or
          post-effective amendment to the Registration Statement or the
          Prospectus or any document incorporated therein by reference or file
          any other required document so that, as thereafter delivered to the
          purchasers of the Common Shares, the Prospectus will not contain any
          untrue statement of a material fact or omit to state a material fact
          necessary to make the statements therein in light of the circumstances
          under which they were made, not misleading.

Notwithstanding anything to the contrary contained herein, the obligation to
prepare and file the Registration Statement or any supplement or post-effective
amendment thereto and any other obligations of GGPI hereunder shall be suspended
if GGPI, relying upon advice of counsel, determines that disclosure of any
information required to be included therein would be adverse to its interests,
but such suspension shall not extend beyond 120 days with respect to any such
specified event.

          (iii) GGPI hereby agrees to indemnify and hold harmless each Initial
     Holder and each person, if any, who controls such Initial Holder (within
     the meaning of either Section 15 of the Securities Act or Section 20 of the
     Exchange Act) from and against any and all losses, claims, damages, costs
     and expenses (including reasonable attorneys' fees) ("Claims") to which
     such Initial Holder or such controlling person may become subject, under
     the Securities Act or otherwise, caused by any untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     or the Prospectus or any amendment or supplement thereto, or caused by 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 shall reimburse such Initial Holder and each such
     controlling person for any legal or other expenses reasonably incurred by
     such Initial Holder in connection with investigating or defending any such
     loss as such expenses are incurred; provided, however, that GGPI shall not
     be liable insofar as any such losses, claims, damages, costs and expenses
     (including reasonable attorneys' fees) are caused by any such untrue
     statement or omission or alleged untrue statement or omission based upon
     information furnished in writing to GGPI by any Initial Holder expressly
     for use therein. Each Initial Holder agrees to indemnify and hold harmless
     GGPI and each person, if any, who controls GGPI (within the meaning of
     either Section 15 of the Securities Act or Section 20 of the Exchange Act)
     from and against any and all Claims to which GGPI or such controlling
     person may become subject, under the Securities Act or otherwise, caused by
     any untrue statement or omission or alleged untrue statement or omission
     based upon such information furnished in writing to GGPI by such Initial
     Holder.

          (iv) Each Initial Holder agrees that, upon receipt of any notice from
     GGPI of the happening of any event of the kind described in Section
     6(c)(ii)(5)(E), such Initial Holder will forthwith discontinue disposition
     of securities pursuant to the Registration Statement until such Initial
     Holder's receipt of the copies of the supplemented or amended Prospectus
     contemplated by Section 6(c)(ii)(8).

     (d) NO OTHER EXCHANGE RIGHTS. The Series C Preferred Units are not
convertible into or redeemable or exchangeable for any other property or
securities of GGPI, the Managing Member, the Company or any other Person at the
option of any holder of Series C Preferred Units except as expressly provided in
this Section 6 or in that certain Debt Maintenance Agreement by and between the
Company and DAI of even date herewith.

     7. TRANSFERS. Notwithstanding anything to the contrary contained in the
Agreement, DAI, and any Permitted DAI Transferee (hereinafter defined) pursuant
to this Section 7, may sell, assign or otherwise transfer all but not part of
its Series C Preferred Units to a single Permitted DAI Transferee, without the
consent of the Managing Member; provided, however, that (i) no such sale,
conveyance or other transfer may be made unless the requirements of Section 8.3
of the Agreement (other than Section 8.3(b) thereof) and the second and fourth
sentences of Section 8.2 of the Agreement are satisfied with respect to such
sale, conveyance or other transfer, (ii) such Series C Preferred Units are held
by one person for purposes of Treasury Regulation ss. 1.7704-1(h)(1)(ii), taking
into account the "look-through" rules of Treas. Reg.ss. 1.7704-1(h)(3), (iii)
the transferor and transferee provide the Company with representations and
covenants reasonably satisfactory to the Company to assure the Company that the
requirements

                                      C-10
<PAGE>

described in (ii) above will be satisfied immediately after the transfer and at
all times thereafter and (iv) the organizational documents of the proposed
transferee prohibit the issuance or the transfer of any membership or other
equity interests in such transferee if such transferee would thereafter be
treated as owned by more than 14 persons under Treas. Reg.ss. 1.7704-1(h)(1),
taking into account the look through rules of Treas. Reg.ss. 1.7704-1(h)(3). For
this purpose, a "Permitted DAI Transferee" shall mean a transferee pursuant to
this Section 7 that is any Person or Entity that is an Affiliate of DAI or a
transferee pursuant to this Section 7 that is any Person or Entity that is an
Affiliate of a Permitted DAI Transferee who was the transferee of Series C
Preferred Units pursuant to this Section 7 by virtue of having itself
constituted an Affiliate of DAI. In addition, DAI and each Permitted DAI
Transferee respectively covenants on behalf of themselves and their respective
direct or indirect equity owners that no issuances of membership or equity
interests or transfers of membership or equity interests in DAI or any DAI
Permitted Transferee or any Person owning a direct or indirect equity interest
in either shall be made or effective if the Series C Preferred Units held by DAI
or the DAI Permitted Transferee would thereafter be treated as owned by more
than 14 persons under Treas. Reg.ss. 1.7704-1(h)(1), taking into account the
look through rules of Treas. Reg.ss.1.7704-1(h)(3).
