such meeting to each Member by delivering such notice to him, her or it
personally or depositing the same in the United States mail, postage prepaid,
directed to him, her or it at the post office address shown upon the records of
the Company.  Service of notice is complete upon mailing.  Personal delivery to
any officer of a corporation or association or to any member of a partnership,

          Section 4.10.  Proxies.  Each Member entitled to vote at a meeting
                         -------
of Members or consent to action without a meeting may authorize another Person
or Persons to act for him, her or it by proxy by an instrument executed in
writing and filed with the Secretary.  A Member may submit such instrument by
telegram, cablegram, facsimile or other means of electronic transmission setting
forth or submitted with information sufficient to determine that such Member
authorized such transmission.  Any copy, facsimile, telecommunication or other
reproduction of the original of either the writing or transmission may be used
in lieu of the original, provided, that it is a complete and legible
                         --------
reproduction of the entire original.  If any such instrument designates two (2)
or more Persons to act as proxies, any proxy may exercise all of the powers
conferred by such written instrument unless the instrument shall otherwise
provide.  No proxy shall be valid for more than one (1) year from the date of
its execution.  Subject to the above, any proxy may be revoked if an instrument
revoking such proxy or a proxy bearing a later date is filed with the Secretary.

          Section 4.11.  Waiver of Notice.  Notice of any meeting may be
                         ----------------
waived either before, at or after such meeting in writing signed by the Member
entitled to the notice.  Attendance by a Member at a meeting shall constitute a
waiver of notice of such meeting, unless the Member objects at the beginning of
the meeting to the transaction of business because the meeting is not lawfully
called or convened, or objects before a vote on an item of business because the
item may not lawfully be considered at that meeting and does not participate in
the consideration of the item at that meeting.

Special Vote, may from time to time admit additional Members to the Company.
All Members shall be required to have an interest in the Company represented by
its Equity Percentage.  Unless otherwise authorized by the Members by a Member
Special Vote in accordance with this Article V, all Members shall hold equity
interests in the Company that are entitled to vote and otherwise have equal
rights and preferences, in accordance with the percentage of Equity Percentage
so held, in all matters, and the Profits or Losses, subject to Regulatory

allocated among the Members of the Company in proportion to the Equity
Percentages held by the Members.  The Members, by vote of not less than a Member
Special Vote, may fix (i) the relative rights and preferences of different
classes and series of equity interests in the Company and (ii) may authorize the
issuance of securities convertible into, or exchangeable for, and options,
warrants and rights to purchase, such equity interests.

          Section 5.2.  Issuance of Additional Equity Interests.  The Members,
                        ---------------------------------------
by a Member Special Vote, may issue additional equity interests in the Company
from time to time to existing or new Members.  Such equity interests may be
issued for any consideration, including, without limitation, cash or other
property, tangible or intangible, received or to be received by the Company or
services rendered or to be rendered to the Company.  At the time of
authorization of the issuance of additional equity interests, the Members shall
state, by resolution, their determination of the fair value to the Company in
monetary terms of any consideration other than cash for which such equity

                                  Article VI.

                  --------------------------------------------

          Section 6.1.  Authority of the Members.  Except as otherwise
                        ------------------------
expressly provided herein, no Member shall have any authority to act for, or to
assume any obligations or responsibility on behalf of, or bind any other Member
or the Company.  Each of the Members represents, warrants and agrees that it
shall disclose in writing to all third parties with whom such Member is in
contact concerning the affairs or the business of the Company that such Member
does not have any authority to act for, or to assume any obligations or
responsibilities on behalf of, the Company unless expressly authorized by the
Board of Managers.

                        -------------------------------------------
Board of Managers shall initially consist of five (5) members, of which two (2)
shall be designated by Apogee and three (3) shall be designated by PPG (each a
"Manager").  The size of the Board of Managers may be changed only by a Member
Special Vote and the number of Managers designated by a Member shall be in the
same proportion as such Member's initial number of designees bears to the
initial size of the Board of Managers until such time as a Member's Equity
Percentage (determined as of any fiscal year-end of the Company) represents less
than 50% of the initial Equity Percentage of such Member; when such event
occurs, the size of the Board of Managers and number of designees assignable to
each Member shall be adjusted to reflect, as accurately as reasonable under the
circumstances, such Member's then-current Equity Percentage.  Subject to the
preceding sentence, each of Apogee and PPG (and any new, additional Member which
is entitled to designate a Manager) may designate a replacement representative
at any time and from time to time for any one or more of the Managers it or they
have designated by giving written notice of such replacement to the Company and
the other Managers, which replacement shall be effective upon the giving of such
notice.  Each Manager shall have one vote with respect to all matters to come
before the Board of Managers.

                        --------
called for any purpose or purposes at any time by the Chair or by any Member who
holds an Equity Percentage of at least 25% and who shall demand such meeting by
written notice given to the Chair specifying the purposes of such meeting.
There shall be at least one regular meeting of the Board of Managers in each
Fiscal Year.

          Section 6.7.  Meetings Held Upon Member Demand.  Within ten (10)
                        --------------------------------
business days after the Chair receives a valid demand for a meeting of the Board
of Managers from a Member, it shall be the duty of the Chair to cause a special
or regular meeting of the Board of Managers, as the case may be, to be duly
called and held on notice no less than ten business days and no later than
twenty (20) business days after receipt of such demand.  If the Chair fails to
cause such a meeting to be called and held as required by this Section 6.7, the
Member or Members making the demand may call the meeting by giving notice as
provided in Section 6.9 at the expense of the Company.

          Section 6.8.  Adjournments.  Any meeting of the Board of Managers
                        ------------
may be adjourned from time to time to another date, time and place.  If any
meeting of the Board of Managers is so adjourned, no notice as to such adjourned
meeting need be given to the Managers present if the date, time and place at
which the meeting will be reconvened are announced at the time of adjournment.

          Section 6.9.  Notice of Meetings.  Unless otherwise required by law,
                        ------------------
written notice of each meeting of the Board of Managers, stating the date, time
and place and, in the case of a special meeting, the purpose or purposes, shall
be given at least ten (10) days and not more than twenty (20) business days
prior to the meeting to every member of the Board of Managers.  A Manager may
waive notice of the date, time, place and purpose or purposes of a meeting of
the Board of Managers.  A waiver of notice is effective whether given before, at
or after the meeting, and whether given in writing, orally or by attendance.
Attendance by a Manager at a meeting is a waiver of notice of that meeting,
unless the Manager objects at the beginning of the meeting to the transaction of
business because the meeting is not lawfully called or convened, or objects
before a vote on an item of business because the item may not lawfully be
considered at that meeting and does not participate in the consideration of the
item at that meeting.

          Section 6.10.  Quorum.  A majority of the Managers shall constitute
                         ------

                         --------------
consent or opposition to a proposal to be acted on at a meeting of the Board of
Managers.  If such Manager is not present at the meeting, such consent or
opposition to a proposal does not constitute presence for purposes of
determining the existence of a quorum, but such consent or opposition shall be
counted as a vote in favor of or against the proposal and shall be entered in
the minutes or other record of action at the meeting, if the proposal acted on
at the meeting is substantially the same or has substantially the same effect as
the proposal to which the Manager has consented or objected.

          Section 6.12.  Conference Communications.  Any or all of the
                         -------------------------
Managers may participate in any meeting of the Board of Managers, or of any duly
constituted committee thereof, by any means of communication through which such
members may simultaneously hear each other during such meeting.  For the
purposes of establishing a quorum and taking any action at the meeting, Managers
participating pursuant to this Section 6.12 shall be deemed present in person at
the meeting; and the place of the meeting shall be the place of origination of
the conference telephone conversation or other comparable communication
technique.

          Section 6.13.  Removal.  Any Manager may be removed from office at
                         -------

vote of a majority of the total number of Managers present and eligible to vote
at a meeting of Managers duly noticed and held and at which a quorum of Managers
is present, and any such act shall be deemed to be the action of the Board of
Managers for all purposes of this Agreement and the Act.

          Section 6.15.  Certain Actions.  The following actions shall require
                         ---------------

of Managers acting by majority vote shall have voted to adopt the recommendation
of Trial Counsel for such matter.  If any such matter is resolved without a

be entitled to notify the other Member or Members of its disagreement and such
disagreement shall trigger the dispute resolution mechanisms set forth in

meeting of the Board of Managers, or any duly constituted committee thereof, may
be taken without a meeting if done in writing and signed by a number of the
members of the Board of Managers, or committee members, whose approval would be
sufficient to approve the action at a meeting at which all of the members of the
Board of Managers (or such committee) were present; provided, that no such

the meeting at which the appointment is to be effective. The Manager may sign or
authorize the written appointment by telegram, cablegram, facsimile or other
means of electronic transmission setting forth or submitted with information
sufficient to determine that the Manager authorized such transmission. Any copy,
facsimile, telecommunication or other reproduction of the original of either the
writing or transmission may be used in lieu of the original, provided, that it
                                                             --------
is a complete and legible reproduction of the entire original. Subject to the
above, any proxy may be revoked if an instrument revoking such proxy or a proxy
bearing a later date is filed by the Manager who originally delivered the proxy
with the Chair. For the avoidance of doubt, the Members acknowledge that any
Manager appointed by a Member who will not be attending a meeting of the Board
of Managers shall be entitled to designate another Person (who shall be a
natural Person) to act as a substitute Manager (with all powers of the absent
Manager) on behalf of the absent, appointed Manager for such meeting.

                                    --------

Financial Officer, a Secretary, a Controller, and four (4) Regional Vice
Presidents (the "Named Officers"), and any other officers and agents that may be
designated from time to time by a vote of a Board Supermajority.  The Members

                        -------------------------------------------
annual meeting of the Board of Managers, all officers shall be elected.  Such
officers shall hold office until the next annual meeting of the Board of
Managers or until their successors are elected and qualified, or until such
office is eliminated by amendment of this Agreement, in the case of the Named
Officers, or a vote of a Board Supermajority, in the case of officers other than
Named Officers.  An officer who is a Manager shall hold office until the
election and qualification of his or her successor even though he or she may
cease to be a Manager.  So long as PPG's Equity Percentage exceeds 50%, the
President, the Chief Financial Officer and the Director of Human Resources shall
be elected by the Managers designated by PPG.  At such time as PPG no longer
holds such Equity Percentage, such officers shall be elected by a Board
Supermajority Vote.  The Controller shall be elected by the Managers designated

Regional Vice Presidents shall be elected by the Managers designated by PPG, and

opportunity to cure would cause harm to the Company) and (ii) if the problem
asserted by the Board of Managers is not cured to the satisfaction of the Board
of Managers (or is not curable on account of a finding of cause) and a majority
of the Board of Managers continues to desire to terminate the Controller, the

                                ---------------

          Section 8.1.   Indemnification.
                         ---------------

          (a) To the fullest extent permitted by law, each Manager, each Named
Officer and the Director of Human Resources and the Director of Materials
Management (both, an "Other Director") (all of the foregoing, individually, an
"Indemnitee") shall be indemnified, held harmless and defended by the Company
from and against any and all losses, claims, damages,

                                       22
<PAGE>

liabilities, whether joint or several, expenses (including legal fees and
expenses), judgments, fines and other amounts paid in settlement, incurred or
suffered by such Indemnitee, as a party or otherwise, in connection with any
threatened, pending or completed claim, demand, action, suit or proceeding,
whether civil, criminal, administrative or investigative, and whether formal or
informal, arising out of or in connection with the business or the operation of
the Company or by reason of the Indemnitee's status as a Manager, Named Officer
or Other Director, regardless of whether the Indemnitee continues to be a
Manager, Named Officer or Other Director of the Company at the time any such
loss, claim, damage, liability or other expense is paid or incurred if (i) the
Indemnitee acted in good faith and in a manner he or she reasonably believed to
be in the best interests of the Company and, with respect to any criminal
proceeding, had no reasonable cause to believe that his or her conduct was
unlawful, (ii) the Indemnitee's conduct did not constitute intentional
misconduct or a material breach of the terms of this Agreement, (iii) the
Indemnitee's conduct did not involve a transaction from which the Manager or
Named Officer or Other Director derived an improper personal benefit, and (iv)
the Indemnitee's conduct was not in material violation of any of the published
business conduct policies of the Company then in effect. The termination of any
action, suit or proceeding by judgment, order, settlement or upon a plea of nolo
contendere, or its equivalent, shall not, of itself, create a presumption that
the Indemnitee acted in a manner contrary to the standards specified in clauses
(i), (ii), (iii) or (iv) of this Section 8.1(a).

          (b) To the fullest extent permitted by law, expenses incurred by an
Indemnitee in defending any claim, demand, action, suit or proceeding subject to
this Section 8.1 shall, from time to time, be advanced by the Company prior to
the final disposition of such claim, demand, action, suit or proceeding upon
receipt by the Company of an undertaking by or on behalf of the Indemnitee to
repay such amount unless it is determined that such Indemnitee is entitled to be
indemnified therefor pursuant to this Section 8.1.

          (c) The indemnification provided by this Section 8.1 shall be in
addition to any other rights to which any Indemnitee may be entitled under any
other agreement, pursuant to any vote of the Managers, as a matter of law or
otherwise, and shall inure to the benefit of the heirs, legal representatives,
successors, assigns and administrators of the Indemnities.

          (d) Any indemnification under this Section 8.1 shall be satisfied
solely out of the assets of the Company and no Indemnitee shall have any
recourse against any Member with respect to such indemnification.

          (e) An Indemnitee shall not be denied indemnification in whole or in
part under this Section 8.1 merely because the Indemnitee had an interest in the
transaction with respect to which the indemnification applies, if the
transaction was not otherwise prohibited by the terms of this Agreement and the
conduct of the Indemnitee satisfied the conditions set forth in Section 8.1(a)
hereof.

          (f) The Company may, but shall have no obligation to, purchase and
maintain insurance covering any potential liability of the Indemnitees for any
actions or omissions for which indemnification is permitted hereunder, including
such types of insurance (including

                                       23
<PAGE>

extended coverage liability and casualty and workers' compensation) as would be
customary for any person engaged in a similar business, and may name the
Indemnitees as additional insured parties thereunder.

          Section 8.2.  Indemnification Procedures; Survival.
                        ------------------------------------

          (a) Promptly after receipt by an Indemnitee of notice of the
commencement of any action that may result in a claim for indemnification
pursuant to Section 8.1 hereof, the Indemnitee shall notify the Company in
writing within thirty (30) days thereafter; provided, however, that any omission
                                            --------  -------
so to notify the Company will not relieve it of any liability for
indemnification hereunder as to the particular item for which indemnification
may then be sought (except to the extent that the failure to give notice shall
have been materially prejudicial to the Company) nor from any other liability
that it may have to any Indemnitee.

          (b) An Indemnitee shall have the right to employ separate counsel in
any action as to which indemnification may be sought under any provision of this
Agreement and to participate in the defense thereof, but the fees and expenses
of such counsel shall be at the expense of such Indemnitee unless (i) the
Company has agreed in writing to pay such fees and expenses, (ii) the Company
has failed to assume the defense thereof and employ counsel within a reasonable
period of time after being given the notice required above or (iii) the
Indemnitee shall have been advised by its counsel that representation of such
Indemnitee and other parties by the same counsel would be inappropriate under
applicable standards of professional conduct (whether or not such representation
by the same counsel has been proposed) due to actual or potential differing
interests between them.  It is understood, however, that the Company shall, in
connection with any one such action or separate but substantially similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses of
only one separate firm of attorneys at any time for all such Indemnitees having
actual or potential differing interests with the Company, unless, but only to
the extent, that the Indemnitees have actual or potential differing interests
with each other that would require separate representation under the applicable
and appropriate standards of professional conduct.

          (c) The Company shall not be liable for any settlement of any such
action effected without its written consent, but if settled with such written
consent, or if there is a final judgment against the Indemnitee in any such
action, the Company agrees to indemnify and hold harmless the Indemnitee to the
extent provided above from and against any loss, claim, damage, liability or
expense by reason of such settlement or judgment.

          (d) The indemnification obligations set forth in Section 8.1 hereof
and this Section 8.2 shall survive the termination of this Agreement.

          Section 9.1.  Registration, Transfer and Exchange.
                        -----------------------------------

          (a) The Company shall keep at the Principal Office a register in which
shall be entered the names and addresses of the Members and all Transfers of
Equity Percentages

          (b) Subject to this Article IX, each Transfer of any portion or all of
a Membership Interest shall be registered on the effective date of the Transfer,
exchange or other issuance; provided, however, that no registration of any
                            --------  -------
Transfer not made in compliance with this Article IX, and to the extent
applicable, Article XIV or Section 19.15, shall be made in the register.

          (c) Transfer of any portion or all of a Membership Interest on the
books of the Company may be authorized only by the Member named in the Company
register, the Member's legal representative or the Member's duly authorized
attorney-in-fact.  The Company may treat as the absolute owner of a Membership
Interest the person or persons in whose name the Membership Interest is
registered on the books of the Company.

          Section 9.2.  Restriction on Transfers.  In addition to any
                        ------------------------
restrictions imposed by the federal securities laws and any applicable state
securities or "blue-sky" laws, except for transfers in accordance with Article
XIV or Section 19.15, no Member may Transfer all or any part of its Membership
Interest, whether for consideration or not, and no transferee thereof shall have
any rights in the Company or be or have any rights as a Member with respect to
all or any part of any such Membership Interest attempted to be Transferred, and
any such attempted Transfer of all or any part of a Membership Interest shall be
entirely null and void, unless Members holding 100% of the outstanding
Membership Interest that is held by non-transferring Members consent to the
Transfer and the admission of such transferee as a Member if such Transfer is to
a Person, other than the Company, who is not then a Member; provided, however,
                                                            --------  -------
that a Member may Transfer any portion or all of a Membership Interest held by
such Member to a Permitted Transferee of such Transferring Member without the
consent of the other Members hereto; provided, further, however, that all rights
                                     --------  -------  -------
under this Agreement, other than to receive the economic benefit thereof, with
respect to a portion of a Membership Interest transferred to a Permitted
Transferee shall be retained by the Transferring Member and, in the event of a
Change in Control of a Permitted Transferee, all such Membership Interest shall
be transferred back to the Transferring Member on or prior to the occurrence of
such Change in Control.  In connection with the Closing, Apogee contemplates
that one or more of its Affiliated Group Subsidiaries may become a Member and a
party to this Agreement; in such event, any such Affiliated Group Subsidiary of
Apogee becoming a Member shall have only the rights of a Permitted Transferee
with respect to its Membership Interest as set forth in the immediately
preceding sentence.  In the event of a Transfer of any portion or all of a
Membership Interest in accordance with this Section 9.2, the transferee shall
become a party to this Agreement as a Member and shall have all of the rights
and obligations of the transferring Member hereunder except to the extent
otherwise provided in this Section 9.2.  The appropriate Company records shall
be noted to prevent any Transfers in violation of this Section 9.2.

<PAGE>

foreclosure of pledge, garnishment, attachment, divorce decree, bankruptcy or
other legal process (or by operation of law resulting from the death,
disability, liquidation, dissolution or winding-up of a Member), such Member
shall cease to be a Member, but any successor to the transferred Membership
Interest shall have no right to become a Member or vote in any Company matters
unless admitted by affirmative vote of a Member or Members who hold 100% of the
Membership Interest other than the Membership Interest so transferred, subject
to the provisions of Section 9.5 hereof. If such successor does not become a
Member, such successor shall be merely an assignee within the meaning of Section
18-702(b) of the Act.

          Section 9.4.  Conditions to Permitted Transfers.  No Transfer
                        ---------------------------------

be confirmed by presentation to the Company of legal evidence of such Transfer,
in form and substance satisfactory to counsel of the Company.

          (b)  Except in the case of an involuntary Transfer of any portion or
all of a Membership Interest by operation of law, where no opinion of counsel is

     federal income tax purposes under Section 708 of the Code;

               (ii)   The Transfer is either exempt from all applicable
     registration requirements and such Transfer will not violate any applicable
     federal and state laws regulating the Transfer of securities, or the
     Membership Interest to be transferred is duly and properly registered under
     all applicable federal and state securities laws; and

               (iii)  The Transfer will not cause the Company to be deemed to be

          (b)  Upon the reasonable written request of any Member, the Board of
Managers, subject to such reasonable standards as may be established from time
to time by the Board of Managers, shall promptly deliver to such requesting
Member (or, to the extent so directed, to its agent or attorney) a copy of the

officers, employees or accountants of the Company, and the Company and its
Subsidiaries shall provide to any Member responses to all reasonable written
requests from a Member for information relating to the Company, its Subsidiaries
and their respective operations; provided, however, that such investigation and
                                 --------  -------
preparation of responses shall not unreasonably interfere with the operations of
the Company or its Subsidiaries, as applicable; and provided, further, that, so
                                                    --------  -------
long as Apogee controls the business of retail automobile glass repair and
replacement operated through its network of "Harmon Retail" shops, it shall
maintain such procedures as are necessary and appropriate to restrict and
exclude Harmon Retail officers and employees from obtaining access to the
information that Apogee may acquire with respect to the operations of the

independent public accountants, if any, to discuss such aspects of the financial
condition of the Company or its Subsidiaries, as applicable, with any such
Member and its representatives as such Member may reasonably request, and to
permit such Member and its representatives to inspect, copy and make extracts

manner, as is reasonably requested by a Member.  Such information may relate to
refund opportunities, estimated payment requirements, IRS or state auditor
requests and the like.

          Section 10.6.  Tax Matters Partner.  In the event that the Members
                         -------------------
elect pursuant to Section 301.6231(a)(1)-IT(a)(4) to apply the TEFRA audit
rules, such election being subject to a Member Special Vote, this Section 10.6
shall apply.  For so long as PPG holds an Equity Percentage in excess of 50%,
PPG shall act as the tax matters partner (the "TMP"), as such term is defined in
Section 6231(a)(7) of the Code, and the TMP is hereby authorized to and shall
represent the Company in connection with all examinations of the Company's
affairs by tax authorities, including resulting administrative and judicial
proceedings.  The Members and the TMP shall use all reasonable efforts to comply
with the responsibilities outlined in the Tax Matters Exhibit and in Sections
6222 through 6231 of the Code (including any Treasury Regulations thereunder and
any successor or amendatory provisions thereto for which a tax matters partner
is designated).

          Section 10.7.  Tax Elections    All tax elections and methods required
                         -------------
or permitted to be made or adopted by the Company under the Code shall require a
Board Supermajority.

                                    -------

          Section 11.1.  Initial Capital Contributions.  Concurrently with the
                         -----------------------------
Closing, as contemplated by the Contribution Agreement, the Persons signing this
Agreement shall make the Capital Contributions indicated opposite their
respective names on Schedule A and become Members.  In exchange for such Capital
Contributions, the Members shall hold the Equity Percentage set forth opposite
their respective names on Schedule A.

          Section 11.2.  Additional Capital Contributions.  In the event that
                         --------------------------------
the Members, by a Member Special Vote, determine, at any time or from time to
time, that an additional Capital Contribution is necessary for the conduct of
the Company's activities, each of the Members shall promptly make a contribution
to the capital of the Company equal to its share (determined in proportion to
the Equity Percentage held by each Member) of such additional Capital
Contribution.  As additional Capital Contributions are needed for the conduct of
the Company's business, if one Member is unable to or otherwise does not
contribute its share of such Capital Contributions to the Company, the Capital
Contributions advanced by the other Member shall be regarded as a loan in
accordance with Section 11.5 hereof.

          Section 11.3.  Special Capital Contributions.    A Member may make
                         -----------------------------
Special Capital Contributions for the purpose of funding any expenditure by the
Company which is to be charged, either by expense, depreciation or amortization,
solely to the Capital Account of such Member pursuant to Section 12.2 of this
Agreement.  A Special Capital Contribution made pursuant to this Section 11.3
shall be credited to the Capital Account of the contributing Member, but shall
not alter the Equity Percentages of the Members as determined under this
Agreement.  PPG may make Special Capital Contributions solely for the purpose of
funding the Defined Benefit Plans, which Special Contributions shall be applied
by the Company solely for that purpose.

          Section 11.4.  No Right to Return of Contribution.  Except as set
                         ----------------------------------
forth in Section 11.9, no Member shall have the right to the withdrawal or to
the return of its Capital Contribution, except upon the dissolution and
liquidation of the Company pursuant to Article XV.

          Section 11.5.  Loans to the Company; No Interest on Capital.  Except
                         --------------------------------------------
for (i) the Initial Credit Facility or replacements or amendments thereto in
accordance with Article VI, and, if applicable, Section 6.15 hereof, and (ii)
Basket Loans made pursuant to Section 13.2 hereof (if made by the Majority
Member), in the amounts, and at the times, required thereby without Board
action, the Members may, but are not obligated to, make loans to the Company
from time to time, as authorized by a Board Supermajority.  Any loans from a
Member shall not be treated as Capital Contributions to the Company for any
purpose hereunder nor entitle such Member to any change in its Equity
Percentage, but the Company shall be obligated to such Member for the amount of
any such loans pursuant to the terms thereof, as the same are determined by a
Board Supermajority and such Member.  Interest with respect to the outstanding
amount of any loans made by a Member to the Company (other than Basket Loans, if
made by the Majority Member, which shall be governed by Section 13.2 hereof)
shall accrue and be payable at such times and at such rate as shall be
determined by a Board Supermajority and such Member.  All scheduled principal
and interest payments with respect to any loans from a Member to the Company
pursuant to this Section 11.5 (other than Basket Loans, if made by the Majority
Member, which shall be governed by Section 13.2 hereof) shall be repaid prior to
any distributions to any Members pursuant to Sections 13.1, 13.3 or 15.3(d)
hereof.  No interest shall be paid on any Capital Contribution to the Company or
on any balance in any Capital Account.

          Section 11.6.  Creditor's Interest in the Company.  No creditor who
                         ----------------------------------
makes a loan to the Company shall have or acquire at any time as a result of
making the loan any direct or indirect interest in the profits, capital or
property of the Company, other than such interest as may be accorded to a
secured creditor.  Notwithstanding the foregoing, this provision shall not
prohibit in any manner whatsoever a secured creditor from participating in the
profits of operation or gross or net sales of the Company or in the gain on sale
or refinancing of the Company, all as may be provided in its loan or security
agreements.

          Section 11.7.  Liability of Members.  Except as otherwise provided
                         --------------------
in the Act, no Member, as such, shall have any personal liability whatsoever to
the Company, any of the other Members or any of the creditors of the Company for
the debts, liabilities, contracts or other obligations of the Company or any of
the Company's losses beyond, with respect to a Member, such Member's Capital
Contribution and, solely to the extent and for the period required by applicable
law, the amount of such Member's Capital Contribution which is returned to it.
Each Membership Interest shall be fully paid and, except as set forth in Section
11.4 hereof, not subject to assessment for additional Capital Contributions.  No
Member shall be required to lend any funds to the Company as a condition to
admission or continued membership of such Member in the Company.  It is the
intent of the Members that (i) no distribution to any Member (other than a
distribution upon the dissolution and liquidation of the Company) shall be
deemed a withdrawal of capital, even if such distribution represents, for
federal income tax purposes or otherwise (in full or in part), a distribution of
depreciation or any other non-cash item accounted

                                       32
<PAGE>

for as a loss or deduction from or offset to the Company's income, and (ii) no
Member shall be obligated to pay any such amount to or for the account of the
Company or any creditor of the Company. However, if any court of competent
jurisdiction holds that, notwithstanding the provisions of this Agreement, any
distribution made by the Company to a Member constitutes a withdrawal of
capital, any obligation under applicable law to return the same or any portion
thereof to or for the account of the Company or its creditors shall be the
obligation of such Member.

          Section 11.8.  Capital Accounts.  A separate capital account
                         ----------------
("Capital Account") shall be maintained by the Company for each Member as
described in the Tax Matters Exhibit.

          Section 11.9  Termination of Defined Benefit Plans.  In the event of
                        ------------------------------------
a termination of a Defined Benefit Plan, any assets and liabilities arising out
of such Defined Benefit Plan shall be distributed to PPG in accordance with
Section 9.3(d) of the Contribution Agreement.

          Section 12.1.  Allocation of Profits and Losses.  Except as
                         --------------------------------
otherwise set forth in Section 12.2 hereof, after giving effect to the
regulatory allocations set forth in Section 12.4 hereof, and subject to Section
12.3 hereof, all Profits and Losses shall be allocated to each of the Members in
proportion to their respective Equity Percentages.

          Section 12.2.  Allocation of Profits and Losses - Special Allocations.
                         ------------------------------------------------------
Notwithstanding Section 12.1. of this Agreement:

          (a) The Members may by resolution agree that an item of income or
expense (and any item of income, gain, loss, deduction or credit attributable to
such item) shall be credited or charged, as the case may be solely to the
Capital Account of a Member.

          (b) Any items of income or expense attributable to the Defined Benefit
Pension Plans shall be allocated solely to PPG, and such allocation shall not
alter the Equity Percentage of any Member, as determined in accordance with the
terms of this Agreement.

          (c) Any item of interest expense relating to any Basket Loan shall be
allocated solely to the Majority Member.

          Section 12.3.  Limitation on Loss Allocation.  Notwithstanding
                         -----------------------------
anything in Section 12.1 hereof, Losses allocated pursuant to Section 12.1
hereof shall not exceed the maximum amount of Losses that can be so allocated
without causing a Member to have an Adjusted Capital Account Deficit at the end
of any Fiscal Year.  In the event one of the Members would have an Adjusted
Capital Account Deficit as a consequence of an allocation of Losses pursuant to
Section 12.1 hereof, the limitation set forth herein shall be applied on a
Member by Member basis so as to allocate the maximum permissible Losses to each
Member under Section

                                       33
<PAGE>

1.704-1(b)(2)(ii)(d) of the Treasury Regulations. All Losses in excess of the
foregoing limitation shall be allocated to the Members in proportion to their
respective Equity Percentages.

          Section 12.4.  Regulatory Allocations.  Notwithstanding anything to
                         ----------------------
the contrary contained in Sections 12.1 or 12.3 hereof or elsewhere in this
Agreement, it is the intention of the Members that Profits and Losses be
allocated in accordance with the "partnership minimum gain chargeback" (Treasury
Regulations Sections 1.704-2(f) and 1.704-2(g)(2)), "partner minimum gain
chargeback" (Treasury Regulations Sections 1.704-2(f)(5), 1.704-2(i)(4), 1.704-
2(i)(5) and 1.704-2(j)(2)), "qualified income offset" and "alternate test for
economic effect" (Treasury Regulations Section 1.704-1(b)(2)(ii)(d)),
"partnership nonrecourse deductions" (Treasury Regulations Section 1.704-
2(b)(1)) and "partner non-recourse deductions" (Treasury Regulations Section
1.704-2(i)(1)) provisions of Treasury Regulations Section 1.704-1(b) and Section
1.704-2 and any successor regulations (collectively, the "Regulatory
Allocations") and, to the extent any provisions of this Agreement do not comply
therewith, the Members desire and intend that such provisions be modified or
stricken in such respects as are necessary in order to cause compliance
therewith.  The Regulatory Allocations that shall govern this Agreement are set
forth in the Tax Matters Exhibit.

          Section 12.5.  Tax Allocations:  Section 704(c) of the Code.  In
                         --------------------------------------------
accordance with Section 704(c) of the Code, income, gain, loss and deduction
with respect to any property contributed to the Company shall, solely for tax
purposes, be allocated among the Members so as to take account of any variation
between the adjusted basis of such property to the Company for income tax
purposes and its book value, in the same manner as such variations are treated
under Section 704(c) of the Code.  The Members hereby agree to use the remedial
allocation method, as described in Treasury Regulation Section 1.704-3(d), for
such allocations relating to all items of inventory contributed to the Company
by the Members.  The Members hereby agree to use the traditional method with
curative allocations as such method is described in Treasury Regulation Section
1.704-3(c), for such allocation relating to all other items of property
contributed to the Company by the Members.  Allocations pursuant to this Section
12.5 are solely for purposes of federal, state and local taxes and shall not
affect, or in any way be taken into account in computing, any Member's Capital
Account or share of income, gain, loss or deduction pursuant to any provision of
this Agreement.

          Section 12.6.  Other Allocation Rules.  In the event of any changes
                         ----------------------
in the Members' Equity Percentages during a Fiscal Year, all Profits and Losses
from operations of the Company during such Fiscal Year, using such methods of
accounting for depreciation and other items as a Board Supermajority determines
to use for federal income tax purposes, shall be allocated to each Member based
on its varying interest in the Company during such operating year in accordance
with Section 706 of the Code.  A Board Supermajority shall determine in
accordance with Section 706 of the Code whether to prorate items of income and
deduction according to the portion of the Fiscal Year for which a Member held a
particular Equity Percentage or whether to close the books on an interim basis
and divide such operating year into two (2) or more segments.  All tax credits
shall be allocated among the Members in accordance with applicable law.

                                 Distributions
                                 -------------

          Section 13.1.  Distributions.
                         -------------

          (a) Within thirty (30) days after the end of each fiscal quarter of
the Company, the Company shall distribute 90% of the Net Cash Flow generated in
such quarter as determined from the quarterly financial reports of the Company
for such quarter; provided that, if the Company's Debt/Cap. Ratio prior to any
                  -------- -----
quarterly distribution exceeds 25%, Net Cash Flow must be used first to reduce
the principal outstanding on such debt such that the Debt/Cap. Ratio will not
exceed 25% subsequent to such distribution.  For the avoidance of doubt, the
Members acknowledge that, to the extent any distribution of Net Cash Flow would
cause the Company's Debt/Cap. Ratio to exceed 25% after such distribution, the
Company shall reduce the amount of such distribution to an amount that would
result in the Company's Debt/Cap. Ratio equaling 25%.  A Board Supermajority may
distribute Net Cash Flow to the Members at such times and in such amounts as it
may determine in its discretion; but, in any event, shall comply with the
immediately preceding sentence of this Section 13.1.  All distributions of Net
Cash Flow shall be distributed to the Members in proportion to their respective
Equity Percentages.  It is the intent of the Members that all distributions
pursuant to this Section 13.1 which occur during the first twenty-four (24)
months following the Closing Date shall be limited to operating cash flow
distributions as such term is defined in Treasury Regulation Section 1.707-4(b).
Any inadvertent distributions in excess of Operating Cash Flow shall be
considered as loans from the Company to the Member.

          (b) Notwithstanding the foregoing, 100% of the net proceeds of any
asset disposition (or series of related asset dispositions), the gross selling
price of which equaled or exceeded $1,000,000, shall, within five (5) business
days of the closing of such disposition (or series of related dispositions), be
distributed to the Members in proportion to their respective Equity Percentages.

          Section 13.2  Advance Distributions for Basket Amounts

          (a) In any Fiscal Year, the sum of (i) Capital Expenditures in excess
of the lesser of (A) 120% of the amount set forth in the Capital Expenditure
Budget properly approved pursuant to Article VI hereof as of the beginning of a
Fiscal Year, or (B) 150% of the depreciation scheduled for such Fiscal Year,
plus (ii) cash loans or cash advances (including payments made by the Company
pursuant to financial guaranties) other than loans or advances to employees in
accordance with the Company's travel and relocation policies then in effect,
such sum, when multiplied by 90% of the Minority Member's then-current Equity
Percentage, shall be treated as "Basket Capital Expenditures."  Basket Capital
Expenditures incurred in a Fiscal Year shall be computed, in the aggregate,
annually, on a cumulative basis ("Basket Amount").  Within thirty (30) days
after the end of each Fiscal Year, the Company shall deliver to the Minority
Member a "Basket Compliance Certificate," certified by the Chief Financial
Officer, which shall set forth, in reasonable detail (including a break-out for
each category described in the first sentence of this paragraph), the Company's
determination of such Fiscal Year's Basket

                                       35
<PAGE>

Capital Expenditures, and the accumulating Basket Amount as of the end of such
Fiscal Year. Within thirty (30) days following the delivery of the Basket
Compliance Certificate with respect to the first Fiscal Year of the Company
after the Closing during which the Basket Amount has equaled or exceeded Seven
Million Five Hundred Thousand Dollars ($7.5 million), an advance distribution
will be made to the Minority Member in the amount of Seven Million Five Hundred
Thousand Dollars ($7.5 million) (an "Advance Distribution"); provided, however,
in the event, for such Fiscal Year, the additional Basket Amount, if any, in
excess of the amount of the initial Advance Distribution equals or exceeds Five
Million Five Hundred Thousand Dollars ($5.5 million), then one or more
additional advance distributions shall be made to the Minority Member in
increments of Five Million Five Hundred Thousand Dollars ($5.5 million)
corresponding to excess Basket Amounts, if any, in the amount of Five Million
Five Hundred Thousand Dollars ($5.5 million) (also, an "Advance Distribution").
Thereafter, within thirty (30) days following the delivery of the Basket
Compliance Certificate with respect to any Fiscal Year of the Company after the
first Fiscal Year following which an Advance Distribution has been made and
during which the subsequent Basket Amount has equaled or exceeded Five Million
Five Hundred Thousand Dollars ($5.5 million), an Advance Distribution will be
made to the Minority Member in such number of increments of Five Million Five
Hundred Thousand Dollars ($5.5 million) as corresponds to the number of Basket
Amounts for such Fiscal Year in the amount of Five Million Five Hundred Thousand
Dollars ($5.5 million). When an Advance Distribution is made, the Basket Amount
at such time will be reduced by the amount of the Advance Distribution then
paid. Any amounts in the Basket Amount in excess of the Advance Distribution
will remain in the Basket Amount, subject to future accumulations and
distributions in accordance with this Section 13.2. All Advance Distributions
made to the Minority Member shall result in a debit to the Minority Member's
Capital Account in an amount equal to such Advance Distribution in a manner
consistent with Section 1 of the Tax Matters Exhibit.

          (b)       (i)   Notwithstanding any other provision of this Agreement
to the contrary, the Company shall obtain an interest-bearing loan from the
Majority Member (if it agrees, in its sole discretion, to do so) or from a third
party in an amount equal to the amount of the Advance Distribution (a "Basket
Loan"), which loan shall be guaranteed by the Majority Member if required by the
third party lender. The proceeds from the Basket Loan shall be paid to the
Minority Member as the Advance Distribution.

                    (ii)  Interest on the Basket Loan shall be paid by the
Company, any such interest payments to be made out of, and reduce, the
distributions which would otherwise be payable to the Majority Member pursuant
to Section 13.1 hereof. Interest expense with respect to the Basket Loan shall
be allocated to the Majority Member in accordance with Section 12.1 hereof. Upon
repayment of the Basket Loan in accordance with this Section 13.2, no further
interest payments shall be made or reduce distributions to the Majority Member.

                    (iii) At the same time that any distribution is paid
pursuant to Section 13.1 hereof, for any fiscal quarter following the obtaining
of a Basket Loan during which there is an amount outstanding on any such Basket
Loan, the Company shall make a payment of principal with respect to such Basket
Loan, such payment to be in the amount of

                                       36
<PAGE>

sixty-six (66%) percent of ten (10%) percent of the Net Cash Flow of the Company
determined in accordance with Section 13.1.

                    (iv)   Any such Basket Loan shall not be counted in
computing the Debt/Cap. Ratio, and shall be disregarded in determining
compliance with Sections 6.15(d), 11.4 and 13.1 hereof.

                    (v)    In no event shall any transaction pursuant to this
Section 13.2 increase or reduce the Equity Percentage of the Majority Member or
the Minority Member.

          (c)  In the event of (i) the consummation of a Reorganization
transaction or (ii) a dissolution or liquidation of the Company in accordance
with this Agreement, the following shall occur:  (a) any balance in the Basket
Amount shall be reduced to zero, (b) there will be no future accumulations to
the Basket Amount or distributions pursuant to subsection (a) of this Section
13.2, and (c) all Advance Distributions paid by the Company pursuant to
subsection (a) of this Section 13.2 shall be repaid, within thirty (30) days
after the consummation of such event, by the Minority Member to the Company
(which repayment will, in the event only of a liquidation and dissolution of the
Company, be made solely by a reduction in the amounts to be distributed to the
Minority Member and, in the event only of a Reorganization transaction, be made
solely by a reduction in the amount of transaction proceeds received by the
Minority Member for such Reorganization transaction).  Any such repayment under
this clause (c) shall be treated as a Capital Contribution by the Minority
Member occurring immediately before such dissolution, liquidation or
Reorganization transaction.

          (d)  In the event of a Change in Control transaction (other than an
"Apogee MBO," as defined below) or in the event of a Transfer of its Membership
Interest by Apogee pursuant to Section 14.3(b)(ii) hereof:

               (i)    any balance in the Basket Amount shall be reduced to zero;

               (ii)   there will be no future accumulations to the Basket
Amount or distributions pursuant to Section 13.2(a) hereof;

               (iii)  in the event that PPG exercises its election under Section
14.1(b)(i) or Section 14.3 (b)(ii) hereof, if applicable, all Advance
Distributions previously paid by the Company to the Minority Member pursuant to
Section 13.2(a) hereof shall be repaid, solely by a reduction in the amount of
transaction proceeds received by the Minority Member pursuant to such election,
in the same proportion of cash-to-promissory note as the Minority Member
receives from PPG pursuant to Section 14.3(b)(i) or Section 14.3(b)(ii), as
applicable, with the ratable portion of such payment in the form of a note to be
repaid to the Company in the same proportion, and at the same time, as PPG pays
its promissory note to the Minority Member;

               (iv)   in the event that PPG exercises its election under Section
     14.1(b)(ii) hereof, if applicable, a pro rata portion, equal to 41.18%, of
                                          --- ----

     Advance Distributions previously paid by the Company to the Minority
     Member pursuant to Section 13.2(a) hereof shall be repaid, solely by a
     reduction in the amount of transaction proceeds received by the Minority
     Member pursuant to such election; the remainder of such Advance
     Distribution to be repaid at the time such payment would otherwise come due
     pursuant to Section 13.2(a) hereof;

                    (v)    in the event that PPG exercises its election under
Section 14.1(b)(iii), if applicable, all Advance Distributions previously paid
by the Company to the Minority Member pursuant to Section 13.2(a) hereof shall
be repaid at the time such payment would come due pursuant to Section 13.2(c)
hereof; and

                    (vi)   in the event that PPG exercises its election under
Section 14.3(b)(ii) hereof, if applicable, all Advance Distributions previously
paid by the Company to the Minority Member pursuant to Section 13.2(a) hereof
shall be repaid at the time such payment would come due pursuant to Section
13.2(c) hereof.

          (e)  In the event of an Apogee MBO, the terms of this Section 13.2
shall continue in full force and effect until such time as more than 50% of the
board of directors of Apogee (or any Person that acquires Apogee, if applicable)
immediately following the closing of the Apogee MBO (or any successors who have
been duly elected by such original members or their duly elected successors) are
no longer members of the board of directors, in which event:

               (i)    any balance in the Basket Amount shall be reduced to zero;

               (ii)   there will be no future accumulations to the Basket Amount
or distributions pursuant to Section 13.2(a) hereof; and

               (iii)  all Advance Distributions previously paid by the Company
to the Minority Member pursuant to Section 13.2(a) hereof shall be repaid at the
time such payment would come due pursuant to Section 13.2(c) hereof.

          (f)  As used herein, "Apogee MBO" means a "going-private" transaction
in which the then-current management of Apogee, at the time Apogee is publicly
held, acquires (with the assistance of independent, third-party financial
sources) Control of Apogee through the leveraged acquisition of a majority of
the outstanding shares of Apogee.

          (g)  At such time that PPG no longer retains the right to designate a
majority of the Board of Managers under Section 6.3 of this Agreement:

               (i)    any balance in the Basket Amount shall be reduced to zero;

               (ii)   there will be no future accumulations to the Basket Amount
or distributions pursuant to Section 13.2(a) hereof; and

               (iii)  all Advance Distributions previously paid by the Company
to the Minority Member pursuant to Section 13.2(a) hereof shall be repaid at the

                         ----------------------------
provision to the contrary in this Article XIII:

          (a)  All distributions made in connection with the liquidation and
winding up of the Company shall be made in the manner provided in Section

                     Member and Poor Financial Performance
                     -------------------------------------

          INTRODUCTORY NOTE:  The Members understand and agree that the terms of
this Article XIV shall apply only for the period during which 100% of the
Company's equity interest is owned solely by PPG and Apogee and their respective
Affiliates.  In the event that an unaffiliated third party becomes a Member, PPG
and Apogee (so long as they are Members) shall in good faith attempt to modify
this Article XIV to consider appropriately the interests of such new Member.
The provisions of this Article XIV shall supersede Section 4.8 as to the
requirement for a Member Special Vote to the extent otherwise applicable, under
Section 4.8.

          Section 14.1.  PPG Purchase Rights Upon a Change in Control of Apogee.
                         ------------------------------------------------------
In the event of a Change in Control of Apogee (Apogee and its successor
resulting from such Change in Control is referred to as the "Minority Member" in
this Section 14.1), PPG shall have the options set forth in this Section 14.1.

          (a)  Within five (5) days of the occurrence of a Change in Control of
Apogee, the Minority Member shall give written notice to PPG and the Company of
such Change in Control, which notice shall contain (i) the date of the Change in
Control of Apogee and (ii) the identity of the Person or Persons to whom control
has been transferred.  The date upon which such notice is given is referred to
herein as the "Apogee Notice Date."

          (b)  Within sixty (60) days of the Apogee Notice Date, PPG shall give
written notice to the Minority Member of its election to do one of the
following:

               (i)    purchase all of the Minority Member's Membership Interest
     at a purchase price equal to the Buy-Out Formula Price (as defined below),
     payable as set forth in subsection (c) of this Section 14.1;

               (ii)   purchase such portion of the Minority Member's total
     Membership Interest as would reduce the Minority Member's total Membership
     Interest to 20% at a

                                       39
<PAGE>

     purchase price determined with reference to the "Buy-Out Formula Price"
     payable as set forth in subsection (d) of this Section 14.1; or

               (iii)  accept the Minority Member without objection, in which
     event the Minority Member shall retain all of the rights and be subject to
     all of the obligations of Apogee under this Agreement.

          In the event PPG does not make an election as required under this
Section 14.1(b) during the sixty (60)-day period, PPG shall be deemed to have
made the election set forth in Section 14.1(b)(iii) hereof.

          As used herein, the "Buy-Out Formula Price" means the greater of (i)
six (6) times 50% of the cumulative, consolidated EBITDA of the Company
determined from the latest twenty-four (24) months of operations of the Company
and its Subsidiaries, adjusted to subtract the outstanding principal and
interest balance of all credit-for-money-borrowed facilities (whether the
remaining maturities thereof are greater than or less than twelve (12) months)
to which the Company is then a party and to add cash on hand and (ii) 120% of
the Company's consolidated net book value, as determined from the Company's
consolidated balance sheet as of its most recently completed month-end, in each
case multiplied by such selling Member's Equity Percentage.  In the event of a
purchase hereunder before the completion of the second full Fiscal Year of the
Company, the Buy-Out Formula Price shall be determined under clause (ii) of the
preceding sentence.

          (c) If PPG exercises its option to purchase all of the Minority
Member's Membership Interest under subsection (b)(i) of this Section 14.1, PPG
shall pay the purchase price determined thereunder one-third in cash with the
balance payable on the fifth anniversary of the Minority Member Purchase Date
(as defined below).  Within thirty (30) days after the later of (i) the date PPG
gives notice of its intention to purchase all of the Minority Member's
Membership Interest and (ii) the date upon which the applicable purchase price
is determined (such date, the "Minority Member Purchase Date"), PPG shall
deliver to the Minority Member one-third of the purchase price, by wire transfer
of immediately available funds, and its promissory note for the balance of the
purchase price in the form of Exhibit 3, which note shall provide for prepayment
of such note without penalty and shall bear interest at a rate per annum
comparable to the then corporate PPG bond rating for comparable maturity
instruments.  On the Minority Member Purchase Date, the Minority Member shall
execute and deliver to PPG such documents and certificates as PPG deems
necessary to effect the transfer to PPG of the Minority Member's Membership
Interest free of all liens and encumbrances.

          (d) If PPG exercises its option to purchase a portion of the Minority
Member's Membership Interest under subsection (b)(ii) of this Section 14.1, PPG
shall pay the purchase price determined thereunder entirely in cash on the
Minority Member Purchase Date, by wire transfer of immediately available funds
to the Minority Member.  On the Minority Member Purchase Date, the Minority
Member shall execute and deliver to PPG such documents and certificates as PPG
deems necessary to effect the transfer to PPG of the portion of the Minority
Member's Membership Interest being purchased by PPG free of all liens and

                                       40
<PAGE>

encumbrances.  As of the Minority Member Purchase Date with regard to a purchase
under subsection (b)(ii) of this Section 14.1, the provisions of this Agreement
under Section 6.15 hereof and elsewhere requiring a Board Supermajority with
respect to the taking of certain actions shall be of no further force and effect
and the Minority Member shall not have any rights with respect thereto as to
actions taken or proposed to be taken after the Minority Member Purchase Date.

          (e)  In the event of a Change in Control of Apogee, Apogee's
Membership Interest may be Transferred to the successor-in-interest to Apogee
without the consent of any other Member and without compliance with the
restrictions on transferability set forth in Section 9.2 hereof, subject only to
Section 9.4 and to the rights of such other Member set forth in this Section
14.1.

          Section 14.2  Apogee Repurchase Right Upon a Change in Control of
                        ---------------------------------------------------
PPG's Glass Business.  In the event of a Change in Control of PPG's Glass
--------------------
Business (as defined below) (PPG and its successor resulting from such Change in
Control is herein referred to as the "Majority Member"), Apogee shall have the
rights set forth in this Section 14.2.  As used herein, "PPG's Glass Business"
means its automotive flat glass manufacturing auto glass fabrication and
automotive replacement glass businesses, so long as these businesses continue to
be an integrated operation; if they are not so integrated, then it shall mean
only PPG's automotive replacement glass business.  For the avoidance of doubt,
PPG's automotive replacement glass business may have a Change in Control
independent from the rest of the PPG Glass Business; therefore, the terms of
this Section 14.2 shall apply to a Change in Control of any of PPG, PPG's Glass
Business or PPG's automotive replacement glass business.

          (a)  Within five (5) days of the occurrence of a Change in Control of
PPG's Glass Business, the Majority Member shall give written notice to Apogee
and the Company of such Change in Control, which notice shall contain (i) the
date of the Change in Control of PPG's Glass Business and (ii) the identity of
the Person or Persons to whom control has been transferred.  The date upon which
such notice is given is referred to herein as the "ARG Notice Date."

          (b)  Within sixty (60) days of the ARG Notice Date, Apogee shall give
written notice to the Majority Member of its election to do one of the
following:

               (i)  require the Majority Member to purchase from Apogee all of
     Apogee's Membership Interest at a purchase price equal to the Buy-Out
     Formula Price, payable in cash as set forth in subsection (c) below; or

               (ii) accept the Majority Member without objection, in which event
     the Majority Member shall retain all of the rights and be subject to all of
     the obligations of PPG under this Agreement.

          (c)  If Apogee exercises its option to require the Majority Member to
purchase all of Apogee's Membership Interest under subsection (b)(i) of this
Section 14.2, the Majority

                                       41
<PAGE>

Member shall pay the purchase price entirely in cash by wire transfer of
immediately available funds to Apogee within thirty (30) days after the later of
(i) the date Apogee gives notice of exercise of its option to require the
Majority Member to purchase all of Apogee's Membership Interest or (ii) the date
upon which the applicable purchase price is determined (such date, the "Apogee
Repurchase Date"). On the Apogee Repurchase Date, Apogee shall execute and
deliver to the Majority Member such documents and certificates as the Majority
Member deems necessary to effect the transfer to the Majority Member of Apogee's
Membership Interest free of all liens and encumbrances.

          (d)  In the event of a Change in Control of any of PPG, PPG's Glass
Business or of PPG's automotive replacement glass business, PPG's Membership
Interest may be Transferred to the successor-in-interest to such business
without the consent of any other Member and without compliance with the
restrictions on transferability set forth in Section 9.2 hereof, subject only to
Section 9.4 and to the rights of such other Member set forth in this Section
14.2.

          Section 14.3  Apogee's Rights in the Event of Poor Financial
                        ----------------------------------------------
Performance.  If at any time subsequent to the fifth anniversary of the date
-----------
hereof (the "Performance Measurement Period"), a "Poor Financial Performance
Event" occurs and is continuing, Apogee shall have the rights set forth in this
Section 14.3.  For purposes hereof, a "Poor Financial Performance Event" shall
be deemed to have occurred and be continuing at any time that with reference to
the immediately preceding trailing twenty-four (24) month period, either (i) the
Company's net earnings have declined by 20% over the applicable prior period or
(ii) the cumulative distributions to the Members have declined by 40% (after
adjusting for any extraordinary expenditures approved in advance by both Members
which have the effect of reducing such distributions) as compared to the
cumulative distributions to the Members during the applicable prior period.

          (a)  If at any time during the Performance Measurement Period, a Poor
Financial Performance Event has occurred and is continuing, Apogee shall have
the right to give written notice to PPG that it is exercising its rights under
this Section 14.3 (an "Apogee Performance Trigger Notice").  The date upon which
such notice is given is referred to herein as the "Apogee Performance Trigger
Notice Date."

          (b)  Within sixty (60) days of the Apogee Performance Trigger Notice
Date, PPG shall give written notice to Apogee of its election to do one of the
following:

               (i)  purchase all of Apogee's Membership Interest at a purchase
     price equal to the Buy-Out Formula Price, payable as set forth in
     subsection (c) of this Section 14.3;

               (ii) permit Apogee to seek to transfer all (but not a portion) of
     Apogee's Membership Interest to a third party in accordance with subsection
     (d) of this Section 14.3;

                                       42
<PAGE>

               (iii)  require Apogee jointly with PPG to pursue a Reorganization
     transaction; or

               (iv)   require Apogee jointly with PPG to pursue a prompt and
     orderly dissolution and liquidation of the Company in accordance with the
     procedures provided in subsection (e) of this Section 14.3.

          In the event PPG does not make an election as required under this
Section 14.3(b) during the sixty (60)-day period, Apogee shall be entitled to
make the election, with such election to be limited to one of  clauses (ii),
(iii) and (iv) above only, such election to be made by written notice to PPG.

          (c)  If PPG exercises its option to purchase all of Apogee's
Membership Interest under subsection (b)(i) of this Section 14.3, PPG shall pay
the purchase price determined thereunder one-third in cash with the balance
payable on the fifth anniversary of the Apogee Performance Trigger Purchase Date
(as defined below). Within thirty (30) days after the later of (i) the date PPG
gives notice of its intention to purchase all of Apogee's Membership Interest
under subsection (b)(i) of this Section 14.3 and (ii) the date upon which the
applicable purchase price is determined (such date, the "Apogee Performance
Trigger Purchase Date"), PPG shall deliver to Apogee one-third of the purchase
price, by wire transfer of immediately available funds, and its promissory note
for the balance of the purchase price in the form of Exhibit 3, which note shall
provide for prepayment of such note without penalty and shall bear interest at a
rate per annum comparable to the then corporate PPG bond rating for comparable
maturity instruments. On the Apogee Performance Trigger Purchase Date, Apogee
shall execute and deliver to PPG such documents and certificates as PPG deems
necessary to effect the transfer to PPG of Apogee's Membership Interest free of
all liens and encumbrances.

          (d)  If PPG permits Apogee to seek to transfer all of Apogee's
Membership Interest to a third party under subsection (b)(ii) of this Section
14.3:

               (i)    In order to transfer all of its Membership Interest to a
     third party, Apogee must first receive a bona fide written offer from a
     third party (the "Transferee") who would meet the general standards for a
     permitted transferee under Section 9.4 hereof (a "Qualified Transferee")
     accompanied by reasonable evidence of the Transferee's ability to finance
     the offer.  Apogee must then submit a copy of that offer to PPG , together
     with a written notice to the effect that Apogee intends in good faith to
     accept that offer.  By doing so, Apogee shall have offered to transfer its
     Membership Interest to PPG on the same terms and conditions as those
     offered by the Transferee (such an offer being referred to as a "Purchase
     Offer").  Apogee shall promptly and in good faith furnish PPG with all
     material non-confidential information which Apogee has about the Purchase
     Offer, the financing that supports the Purchase Offer and the Transferee,
     including, for example, information bearing on whether the Transferee is a
     Qualified Transferee.

               (ii)   Provided that the Transferee is a Qualified Transferee and
     there is reasonable evidence to support the Transferee's ability to finance
     the offer, PPG shall

                                       43
<PAGE>

     either accept the Purchase Offer or reject the Purchase Offer by so
     advising Apogee in writing no later than sixty (60) days after PPG receives
     the Purchase Offer. If PPG fails to make a timely election, PPG shall be
     deemed to have rejected the Purchase Offer. If PPG accepts the Purchase
     Offer, its acceptance shall specify the place and time (which shall be no
     later than thirty (30) days after its acceptance or such later date, if
     any, as is specified in the Transferee's offer) at which the closing of the
     transfer described in the Purchase Offer shall take place. Unless they
     mutually agree otherwise, PPG and Apogee shall proceed to close the
     transfer in accordance with the Purchase Offer and such schedule. If PPG
     rejects the Purchase Offer or is deemed to have done so, then, during the
     forty-five (45) days after that rejection, Apogee shall be entitled, but
     not obligated, to transfer its Membership Interest to the Transferee on
     terms and conditions that are no more favorable to the Transferee than
     those specified in the Purchase Offer. After a transfer to a Transferee in
     accordance with this Section 14.3, the Membership Interest so transferred
     shall continue to have all of the rights and be subject to all of the
     obligations set forth in this Agreement and the Transferee shall become a
     party to this Agreement in accordance with Article IX.

          (e)  If PPG elects jointly with Apogee to pursue a dissolution and
liquidation of the Company, the parties will follow the procedures set forth in
this subsection (e) in addition to complying with Article XV:

               (i)    PPG shall select, and thereafter be the sole owner of, two
     (2) branches (and all Company assets located therein and all Company
     liabilities and obligations specifically associated with such locations) of
     the Company's then-existing network of distribution locations (the
     "Network");

               (ii)   Apogee shall then select, and thereafter be the sole owner
     of, one branch (and all Company assets located therein and all Company
     liabilities and obligations specifically associated with such location) of
     the Network;

               (iii)  the Members shall continue as set forth in clauses (i) and
     (ii) above until there are either no branches of the Network remaining or
     each Member has had the opportunity to, but has declined to, select any
     remaining branches (any such unselected branch is herein referred to as an
     "Orphan Branch");

               (iv)   the Company shall be responsible for closing all Orphan
     Branches, and all associated costs thereof;

               (v)    all other Company assets unrelated to a specific branch
     (or held in an Orphan Branch) shall be divided between the members by
     mutual agreement; provided, that, if they are unable to so agree with
                       --------

     asset shall purchase it from the Company for cash payable at transfer of
     such asset;

               (vi)   the Company shall be responsible for all severance or
     other costs associated with a dissolution and liquidation of the Company
     that are not directly related to any branch selected by one of the Members;

               (vii)  the Members shall determine the value of all assets
     acquired (such values to be used for purposes of adjusting the "Gross Asset
     Values" (as defined in Exhibit 2 hereto) of Company assets as required by
     paragraph (ii) of the definition of Gross Asset Value) and liabilities
     assumed by each Member pursuant to the mechanism set forth above (the
     "Draft Value"); if a Member's Draft Value exceeds such Member's Capital
     Account, then such Member shall promptly pay to the Company an amount in
     cash equal to such excess;

               (viii) to the extent lawful and reasonable to do so, all
     employees located at a specific branch (excepting market managers and sales
     associates) will be allocated to such branch;

               (ix)   to the extent lawful and reasonable to do so, PPG and
     Apogee shall use a selection method similar to that set forth in clauses
     (i) and (ii) above to allocate employees of the Company not so associated
     with a specific branch (e.g., headquarters staff, sales associates and
     market managers) until each Member has declined to select any remaining
     employees of the Company. Any such employees who are not so selected, plus
     all employees employed at Orphan Branches, are hereby referred to as
     "Orphan Employees," and all obligations with respect to Orphan Employees
     shall remain with the Company in accordance with the terms of clause (vi)
     above; and

               (x)    each party will cooperate to obtain a transfer of the
     employees, assets and liabilities selected through the procedures set forth
     above.

          (f)  In the event that PPG elects either option (b)(ii) or (b)(iii) of
this Section 14.3 and a closing thereunder does not occur within six (6) months
of the Apogee Performance Trigger Notice Date, PPG and Apogee will be obligated
(unless they mutually agree otherwise) to pursue a dissolution and liquidation
of the Company in accordance with the procedures set forth in subsection (e) of
this Section 14.3 and Article XV.

                                       45

the forty-five (45) day period following the PPG Performance Trigger Notice Date
to enter into a bona fide agreement with an unaffiliated third party for the
sale of all of PPG's Membership Interest to such third party and to require that
Apogee sell all of its Membership Interest to such party at a price and on terms
and conditions the same as those on which PPG has agreed to sell its Membership
Interest. PPG shall promptly notify Apogee in writing that it has entered into a
bona fide agreement as referred to in the immediately preceding sentence and
shall include a copy of such agreement with such notice. Subject to its right to
verify that PPG has complied with its obligations hereunder, Apogee shall as
promptly as practicable enter into such other agreements as shall be necessary
to comply with the provisions of this Section 14.4.

          (c) In the event that PPG elects to pursue a Reorganization
transaction under subsection (b)(i) of this Section 14.4 and a closing
thereunder does not occur within six (6) months of the PPG Performance Trigger
Notice Date, PPG and Apogee will be obligated (unless they mutually agree
otherwise) to pursue a dissolution and liquidation of the Company in accordance
with the procedures set forth in Section 14.3 (e) and Article XV.

of the Members represents and warrants as of the date of this Agreement to the
other Member and the Company as follows:

          (a) The Membership Interest being acquired by such Member in
connection with the Closing is being purchased for such Member's own account and
not with a view to, or for sale in connection with, any distribution or public
offering thereof within the meaning of the Securities Act of 1933, as amended
(the "Securities Act").  Such Member understands that such Membership Interest
will not be registered under the Securities Act or any state securities laws by
reason of its contemplated issuance in transactions exempt from the registration
and prospectus delivery requirements thereof and that the reliance of the
Company and others upon such exemptions is predicated in part by the
representations and warranties of such Member contained herein.

          (b) Such Member has the requisite power and authority (whether
corporate or otherwise) and legal capacity to enter into, and to carry out its
obligations under, this Agreement.

          (c) The execution and delivery by such Member of this Agreement and
the consummation by such Member of the transactions contemplated hereby have
been duly authorized prior to the date of this Agreement by all necessary action
on the part of such Member.

          (d) This Agreement has been duly executed and delivered by such Member
and constitutes a valid and binding obligation enforceable against such Member
in accordance with its terms.

          (e) Such Member is not subject to, or obligated under, any provision
of (i) any agreement, arrangement or understanding, (ii) any license, franchise
or permit or (iii) any law,

                                       48
<PAGE>

regulation, order, judgment or decree that would be breached or violated, or in
respect of which a right of termination or acceleration or any encumbrance on
any of such Member's assets would be created, by such Member's execution,
delivery and performance of this Agreement or the consummation of the
transactions contemplated hereby, except for such agreements as to which a
                                  ------
Member has previously obtained the consent of the other party or parties
thereto.

          (f) No authorization, consent or approval of, waiver or exemption by,
or filing or registration with, any public body, court, third party or authority
is necessary on such Member's part, which has not previously been obtained by
such Member for the consummation of the transactions contemplated by this
Agreement.

          (g) No person or entity has or will have, as a result of any act or
omission by such Member any right, interest or valid claim against the Company
or any other Member for any commission, fee or other compensation as a finder or
broker, or in any similar capacity, in connection with the transactions
contemplated by this Agreement.

                            Miscellaneous Provisions
                            ------------------------

          Section 19.1. Channel Conflict; Confidentiality and Nonsolicitation.
                        -----------------------------------------------------

          (a)  Channel Conflict.  The Members have agreed to certain principles
               ----------------
involving the distribution of automotive windshields and tempered glass by the
Company and the Members, as follows, which principles shall apply so long as
PPG's Equity Percentage exceeds 50%:

               (i)   As the Company is a controlled subsidiary of PPG, sales and
     pricing to customers by the Company will be coordinated and set by PPG
     (independently of Apogee), subject to the principles set forth in a Channel
     Conflict Document ("CCD") agreed by the parties of even date herewith.

               (ii)  Except for sales of automotive windshields and tempered
     glass to the CCD customers listed in the CCD, and limited to the quantities
     identified in the CCD, either or both PPG and/or the Company may make sales
     to any customers in any quantities.

               (iii) In all situations in which PPG and the Company may make
     sales to the same customers, PPG has the right to coordinate sales and
     pricing to all such customers by the Company and by PPG.

               (iv)  Except for sales of automotive windshields and tempered
     glass to the CCD customers listed in the CCD, and limited to the quantities
     identified in the CCD, Apogee may make sales to any customers in any
     quantities at prices independently set by Apogee.  Apogee agrees that it
     shall prevent the disclosure to any employees of Apogee or its subsidiaries
     who have any involvement in sales under this Section

                                       49
<PAGE>

     19.1(a)(iv), of any proprietary, commercial information of the Company or
     PPG regarding pricing to customers of the Company or PPG.

If a Member believes, in good faith, that the market for distribution of such
products has materially changed after the date hereof such that the procedures
set forth in the CCD no longer are commercially viable, such Member shall be
entitled to propose modifications to the CCD, which modifications shall only be
effective upon a Member Special Vote.  If the Members do not agree to such
proposed modifications, such Member shall be entitled to trigger the dispute
resolution procedures set forth in Section 19.15 hereof.

          (b) Confidentiality.  Except as consented to by the Company and as and
              ---------------
to the extent required by law, each Member hereby agrees that neither it nor any
of its Affiliates will, directly, indirectly or otherwise, disclose, publish,
make available to, or use for its own benefit or the benefit of any Person for
any reason or purpose whatsoever, any Confidential Information; provided,
                                                                --------
however, that no Member or Affiliate thereof shall be obligated to treat as
-------
confidential any Confidential Information that (i) was publicly known at the
time of disclosure to such Member or Affiliate, (ii) becomes publicly known or
available thereafter other than by any means in violation of this Agreement or
any other duty owed to the Company by any person or entity or (iii) is lawfully
disclosed to such Member or Affiliate by a third party.  The parties hereto
stipulate and agree that the foregoing matters are important, material and
confidential proprietary information and trade secrets that affect the
successful conduct of the business of the Company (and any successor or assignee
of the Company).

          (c) Non-Solicitation.  In addition, each Member hereby agrees that,
              ----------------
during the Nonsolicitation Period, neither such Member nor any of its Affiliates
will, either on its own account or jointly with or as an advisor, agent,
representative, principal, partner, joint venturer, owner or equity holder or
otherwise on behalf of any other Person, directly or indirectly solicit or
attempt to solicit away from the Company, or otherwise interfere with the
employment relationship with, any officer, employee, representative or other
agent of the Company or offer employment to any person who, on or during the six
(6) months immediately preceding the date of such solicitation or offer, is or
was an officer, employee, representative or other agent of the Company;
provided, however, that the foregoing restrictions shall not apply to a Member
--------  -------
with respect to officers of the Company who remain employees of such Member; and
provided further, however, after three (3) years from the Closing, the foregoing
-------- -------  -------
restriction shall not apply to a Member or its Affiliate soliciting or
attempting to solicit up to two (2) Company employees per year who have the
equivalent of 551 "Hay points" or more, provided such employees who are to be
employed by a Member or its Affiliate remain employed by the Company for up to
ninety (90) days to allow a replacement to be hired.

          (d) Acknowledgment and Enforcement.  Each Member agrees that the
              ------------------------------
restrictions and agreements contained in this Section 19.1 are reasonable and
necessary to protect the legitimate interests of the Company and the other
Member and its Affiliates and that any breach of this Section 19.1 will cause
substantial and irreparable harm to the Company and the non-breaching Member and
its Affiliates that would not be quantifiable and for which no adequate remedy
would exist at law.  Accordingly, the Company and the non-breaching Member

                                       50
<PAGE>

shall each be entitled to obtain injunctive or other equitable relief for any
violation of this Section 19.1, without the necessity of proving damages or
posting of any bond, and such equitable relief shall be in addition to any other
remedies, whether at law or in equity, that may be available to the Company and
the non-breaching Member. Furthermore, each Member acknowledges and agrees that
if the Company fails to enforce this Section 19.1, each Member may take such
action as it deems necessary to ensure compliance by the other Member with the
terms of this Section 19.1.

          (e) Blue Pencil Doctrine.  If the duration or geographical extent of,
              --------------------
or business activities covered by, this Section 19.1 are in excess of what is
valid and enforceable under applicable law, then such provision shall be
construed to cover only that duration, geographical extent or activities that
are valid and enforceable.  Each Member acknowledges the uncertainty of the law
in this respect and expressly stipulates that this Agreement is to be given the
construction which renders its provisions valid and enforceable to the maximum
extent (not exceeding its express terms) possible under applicable law.

          Section 19.2.  Additional Actions and Documents.  Each of the
                         --------------------------------
Members hereby agrees to take or cause to be taken such further actions, to
execute, acknowledge, deliver and file, or cause to be executed, acknowledged,
delivered and filed such further documents and instruments, and to use all
reasonable efforts to obtain such consents, as may be necessary or as may be
reasonably requested in order to fully effectuate the purposes, terms and
conditions of this Agreement.

          Section 19.3.  Notice.  Any notice or other communication to any
                         ------
party in connection with this Agreement shall be in writing and shall be sent by
manual delivery, facsimile transmission, overnight courier or United States mail
(first class, postage prepaid) addressed, if to the Company, to the principal
office of the Company set forth in Section 1.2 hereof or to such other address
as the Company shall notify the Members in writing; and if to the Members, to
their respective addresses set forth in Schedule A hereof or in the register
maintained by the Company, or to such other address as any such Member may
hereafter designate by notice in writing to the Chair and Company.  All periods
of notice shall be measured from the date of delivery thereof if manually
delivered, when receipt is acknowledged if sent by facsimile transmission, from
the first business day after the date of sending if sent by overnight courier,
or from four (4) days after the date of mailing if mailed.

          Section 19.4.  Severability.  The invalidity of any one or more
                         ------------
provisions hereof or of any other agreement or instrument given pursuant to or
in connection with this Agreement shall not affect the remaining portions of
this Agreement or any such other agreement or instrument or any part thereof;
and in the event that one or more of the provisions contained herein or therein
should be invalid, or should operate to render this Agreement or any such other
agreement or instrument invalid, this Agreement and such other agreements and
instruments shall be construed as if such invalid provisions had not been
inserted.

                                       51
<PAGE>

          Section 19.5.  Survival.  It is the express intention and agreement
                         --------
of the Members that all covenants, agreements, statements, representations,
warranties and indemnities made in this Agreement shall survive the execution
and delivery of this Agreement.

          Section 19.6.  Waivers.  Neither the waiver by a Member of a breach
                         -------
of or a default under any of the provisions of this Agreement, nor the failure
of a Member, on one or more occasions, to enforce any of the provisions of this
Agreement or to exercise any right, remedy or privilege hereunder shall
thereafter be construed as a waiver of any such provisions, rights, remedies or
privileges hereunder.

          Section 19.7.  Exercise of Rights.  No failure or delay on the part
                         ------------------
of a Member or the Company in exercising any right, power or privilege hereunder
and no course of dealing between the Members or between a Member and the Company
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power or privilege hereunder preclude any other or further exercise
thereof or the exercise of any other right, power or privilege.  The rights and
remedies herein expressly provided are cumulative and not exclusive of any other
rights or remedies which a Member or the Company would otherwise have at law or
in equity or otherwise.

          Section 19.8.  Binding Effect.  Subject to any provisions hereof
                         --------------
restricting assignment, this Agreement shall be binding upon and shall inure to
the benefit of the Members and their respective successors and permitted
assigns.

          Section 19.9.  Limitation on Benefits of this Agreement.  It is the
                         ----------------------------------------
explicit intention of the Members that no person or entity other than the
Members and the Company is or shall be entitled to bring any action to enforce
any provision of this Agreement against any Member or the Company, and that the
covenants, undertakings and agreements set forth in this Agreement shall be
solely for the benefit of, and shall be enforceable only by, the Members (or
their respective heirs, legal representatives, successors and assigns as
permitted hereunder) and the Company; provided, however, that the Indemnitees
                                      --------  -------
shall, as intended third-party beneficiaries thereof, be entitled to the
enforcement of Sections 8.1 and 8.2 hereof, but only as insofar as the
obligations sought to be enforced thereunder are those of the Company.

          Section 19.10.  Waiver of Partition.  The Members hereby waive any
                          -------------------
right of partition or any right to take any action that otherwise might be
available to them for the purpose of severing their relationship with the
Company or interest in assets held by the Company from the interest of the other
Members, except to the extent consistent with Article XIV and XV and Section
19.15 hereof.

          Section 19.11.  Entire Agreement.  This Agreement, any Schedules and
                          ----------------

the masculine, feminine, neuter, singular or plural, as the identity of the
antecedent may require.

          Section 19.13.  Headings.  Article and Section headings contained in
                          --------
this Agreement are inserted for convenience of reference only, shall not be
deemed to be a part of this Agreement for any purpose, and shall not in any way
define or affect the meaning, construction or scope of any of the provisions
hereof.

          Section 19.14.  Governing Law.  This Agreement, the rights and
                          -------------
obligations of the parties hereto, and any claims or disputes relating thereto,
shall be governed by and construed in accordance with the laws of the State of
Delaware (but not including the choice of law rules thereof).

hereof (any such controversy, claim or dispute, a "Dispute"), as follows:

          (a) At the written request of a Member, each Member will direct its
Chief Financial Officer for Apogee and Senior Vice President, Finance for PPG to
meet and negotiate in good faith to resolve any Dispute.  The location, format,
frequency, duration and conclusion of these discussions shall be left to the
discretion of the Members, but may include participation by one or more of the
Managers designated by either Member.  Upon agreement between the Members, the
Members may utilize other alternative dispute resolution procedures such as
mediation to assist in the negotiations.  Discussions and correspondence among
the representatives of the Members for the purposes of these negotiations shall
be treated as Confidential Information developed for the purposes of settlement,
exempt from discovery and production, which shall not be admissible in any
lawsuit without the concurrence of both Members.  Documents identified in or
provided with such communications, which are not prepared for purposes of the
negotiations, are not so exempted and may, if otherwise admissible, be admitted
in evidence in such lawsuit or other binding proceeding agreed to by the
Members.

          (b) If the negotiations required by Section 19.15(a) hereof do not
resolve the Dispute within thirty (30) days after the initial written request,
the Members shall jointly select a neutral third party as a mediator to assist
the Members in resolving such Dispute, and continue to negotiate in good faith
to resolve the Dispute.

          (c) With respect only to Disputes that would not, with the passage of
time without resolution, enable a Member to deliver a Dispute Trigger Notice
under subsection (d) of this Section 19.15, in the event that the mediation
provided under subsection (b) of this Section 19.15 does not resolve the Dispute
within forty-five (45) days after commencement thereof, then the parties will
resolve such Dispute under the provisions of this subsection (c).  Any
unresolved Dispute shall be settled by binding arbitration in accordance with
the then current CPR Rules for Non-Administered Arbitration in effect on the
date of the referral of such dispute to arbitration

                                       53

by three (3) independent and impartial arbitrators, none of whom shall be
appointed by either party, provided however, at least one (1) arbitrator shall
be a retired judge (collectively, the "Arbitrators"). The arbitration shall be
governed by the Federal Arbitration Act, 9 U.S.C. (S)1-16 (the "Federal
Arbitration Act") to the exclusion of state laws inconsistent therewith and
judgment upon the award rendered by the Arbitrators may be entered by any court
having jurisdiction thereof. The Arbitrators are not empowered to award a
monetary amount in excess of compensatory damages sufficient to reimburse fully
and make whole the prevailing party for all direct, out-of-pocket costs and
expenses, including reasonable attorney's fees, incurred by the prevailing
party, it being understood that the prevailing party shall also be entitled to
reimbursement for additional direct, out-of-pocket costs and expenses, including
reasonable attorneys' fees, that must be incurred by such prevailing party after
the date of the Arbitrators' award on account of the same set of facts and
circumstances giving rise to that award. Each party hereby irrevocably waives
the right to recover any excess monetary damages with respect to disputes
resolved by arbitration herein. Either party shall have the right to seek, at
its own cost and expense, preliminary and temporary injunctive relief solely to
preserve the status quo of the parties, pending the Arbitrators' determination.
The following procedures shall apply:

               (i)   unless the parties agree otherwise, the place of
     arbitration shall be in Pittsburgh, Pennsylvania if the arbitration is
     initiated by Apogee and Minneapolis, Minnesota if the arbitration is
     initiated by PPG;

               (ii)  the parties may review and delete potential Arbitrators
     from the panel list before final selection of the arbitration panel is made
     from such list;

               (iii) prior to the actual arbitration hearing, each party shall
     provide the Arbitrators, in writing, with the exact ruling (monetary and/or
     otherwise) that it seeks the Arbitrators to render on its behalf;

               (iv)  the Arbitrators, acting by at least a two (2) to one (1)
     majority determination, must render their decision in favor of one party or
     the other in the exact form of the ruling requested by the prevailing
     party;

               (v)   the Arbitrators must determine the prevailing party by
     interpreting the meaning and intent of the language of the Agreement,
     applying the applicable law to the relevant facts and picking the
     arbitration ruling proposed by the party that most closely correlates to
     their decision based upon the Agreement, the applicable law and the
     relevant facts;

               (vi)  the losing party shall pay all costs, fees and expenses of
     the Arbitrators and the arbitration process charged to the parties.  This
     does not include the cost of attorneys' fees, travel costs, preparation
     time or other costs incurred by the parties or their witnesses, including
     experts, which costs shall be paid by the party incurring them;

               (vii) except as provided in the Federal Arbitration Act, the
     decision of

                                       54
<PAGE>

     the Arbitrators is final and binding on the parties, and no appeal of any
     kind may be taken;

               (viii) unless otherwise provided in the Agreement, the statute
     of limitations of the State of Delaware applicable to the commencement of a
     lawsuit shall apply to the commencement of an arbitration hereunder, except
     that no defenses shall be available based upon the passage of time during
     any negotiation or mediation called for by subsection (b) of this Section
     19.15; and

               (ix)   in the event of any inconsistency or conflict between this
     subsection (c) of Section 19.15 and the applicable CPR Rules for Non-
     Administered Arbitration, this subsection (c) of Section 19.15 shall govern
     and control.

          (d)  With respect only to a Dispute regarding an action requiring
either a Member Special Vote (including a failure to obtain a quorum at a Member
meeting on two (2) consecutive occasions to consider such a matter) or a Board
Supermajority that is continuing without resolution sixty (60) days after the
Members have obtained the assistance of a neutral mediator in accordance with
subsection (b) of this Section 19.15, either Member shall have the right to send
written notice that it is exercising its dispute trigger rights under this
Section 19.15 with the consequence set forth herein (a "Dispute Trigger
Notice").

          (e)  If Apogee sends a Dispute Trigger Notice to PPG in accordance
with subsection (d) of this Section 19.15, such Dispute Trigger Notice will have
the same legal force and effect and thereby give rise to the same rights and
obligations as the delivery of an Apogee Performance Trigger Notice under
Section 14.3.

          (f)  If PPG sends a Dispute Trigger Notice to Apogee in accordance
with subsection (d) of this Section 19.15 (a "PPG Dispute Trigger Notice"),
Apogee will respond in writing within sixty (60) days to PPG as to its
preference of either:

               (i)  PPG purchasing all of Apogee's Membership interest at the
     purchase price and on the same payment schedule as would be obtained under
     a purchase of all of Apogee's Membership Interest pursuant to Section
     14.3(b)(i) and 14.3(c); or

               (ii) dissolution and liquidation of the Company in accordance
     with the procedures provided in Section 14.3 and Article XV.

          (g)  If Apogee requests in its response a purchase of all of its
Membership Interest under subsection (e)(i) of this Section 19.15, PPG will
respond in writing within sixty (60) days that it will either:

               (i)  complete such purchase as if it was purchasing all of
     Apogee's Membership Interest pursuant to Section 14.3 (in which event PPG
     will be obligated to complete such purchase in accordance with the
     requirements of Section 14.3); or

                                       55
<PAGE>

               (ii) dissolve and liquidate the Company in accordance with the
     procedures provided in Section 14.3(e) and Article XV.

In the event that PPG does not make an election as required under this Section
19.15(f) within the sixty (60)-day period described above, PPG shall be deemed
to have made the election set forth in Section 19.15(f)(ii) hereof.

          (h) If Apogee either requests in its response a dissolution and
liquidation under subsection (e)(ii) of this Section 19.15 or does not respond
to the PPG Dispute Trigger Notice within the sixty (60) days provided, PPG will
pursue a dissolution and liquidation of the Company in accordance with the
procedures provided in Section 14.3(e) and Article XV.

          For the avoidance of doubt, the Members agree that, except for a
Member's right to propose modifications to the Channel Conflict Procedures and,
if rejected, to treat such rejection as a "Dispute" for purposes of this Section
19.15, no amendment of this Agreement proposed by a Member that is not adopted
by Member Special Vote shall, in and of itself alone (and without taking into
account other circumstances which may bear on such proposal) enable a Member to
trigger the dispute resolution mechanisms of this Section 19.15.  Either Member
may enforce its rights under subsections (d)-(h) of this Section 19.15, as the
case may be, through the binding arbitration procedures set forth in subsection
(c) of this Section 19.15.

          Section 19.16.  Jurisdiction; Venue; Process.  The parties to this
                          ----------------------------
Agreement agree that jurisdiction and venue in any action brought by any party
hereto pursuant to this Agreement shall properly (but not exclusively) lie in
any federal or state court located in the State of Minnesota, County of Hennepin
or the Commonwealth of Pennsylvania, County of Allegheny.  By execution and
delivery of this Agreement, the parties hereto irrevocably submit to the
jurisdiction of such courts for itself and in respect of its property with
respect to such action.  The parties hereto irrevocably agree that venue would
be proper in such court, and hereby waive any objection that such court is an
improper or inconvenient forum for the resolution of such action.  The parties
further agree that the mailing by certified or registered mail, return receipt
requested, of any process required by any such court shall constitute valid and
lawful service of process against them, without necessity for service by any
other means provided by statute or rule of court.

          Section 19.17.  Execution in Counterparts.  To facilitate execution,
                          -------------------------
this Agreement may be executed in as many counterparts as may be required; and
it shall not be necessary that the signatures of, or on behalf of, each party,
or that the signatures of all Persons required to bind any party, appear on each
counterpart; but it shall be sufficient that the signature of, or on behalf of,
each party, or that the signatures of the Persons required to bind any party,
appear on one or more of the counterparts.  All counterparts shall collectively
constitute a single Agreement.  It shall not be necessary in making proof of
this Agreement to produce or account for more than a number of counterparts
containing the respective signatures of, or on behalf of, all of the parties
hereto.
