parties pursuant to Section 1.7 is less than $300,000, and such difference is
greater than $25,000, the Purchase Price shall be reduced by the amount of such
difference and, if Schott has already paid the Purchase Price, Electro shall pay
Schott such amount, or if Schott has not already paid the Purchase Price, Schott
shall pay the Purchase Price as so reduced. For these purposes, the "Net Worth"
of the Company shall mean the total Transferred Assets less the total Assumed
Liabilities. Any purchase price adjustment made pursuant to this Section 1.8
shall not be counted toward the $75,000 thresholds described in Section 12.1.

     (a)  Immediately following the Closing, Electro shall contribute 
$300,000 in cash to the Company as paid-in capital.

     (b)  CML agrees that any indebtedness of Electro or CML Fiberoptics to
CML, as assumed by the Company, shall not bear interest while such indebtedness
remains outstanding, and that CML shall not demand any payment of principal of
such indebtedness until such time as the Company shall have consented, by vote
of two-thirds of the interests of the Members of the Company, to make a payment
of principal, and then only to the extent that the Company so consents. CML
acknowledges that at no time shall the Members of the Company be under any
obligation to consent to the repayment of such indebtedness.

     1.10  Dispute Resolution.  In the event that Schott objects to the
Electro/CML Fiberoptics Balance Sheet in writing to CML within forty-five (45)
days of the receipt of such Electro/CML Fiberoptics Balance Sheet, Schott and
CML shall attempt to resolve any such objection within ten (10) business days of
Schott's objections. If Schott and CML are unable to resolve the matter within
such ten (10) business day period, they shall, within the next ten (10) business
days after the end of such period, jointly appoint an independent public
accounting firm of nationally recognized standing which has not been involved in
any audit of, or the rendering of accounting or other advice to, either Schott
or CML or any of their subsidiaries, within a one-year period prior to the date
of such appointment, to resolve the dispute and make any adjustment to the
figures. This accounting firm shall complete the resolution of the dispute and
make appropriate adjustments to the figures within a ten (10) business day
period. The fees of this public accounting firm shall be divided and paid
equally by CML and Schott. Such a firm's resolution of the dispute and its
adjustments shall be conclusive and binding upon the parties. The public
accounting firm shall provide written notice of such resolution to Schott and
CML. The date of such notice shall be deemed to be the date of final resolution
of the dispute.

         16.1    Other Parties.  Nothing in this Agreement, whether express or
implied, is intended to confer any rights or remedies under this Agreement on
any persons other than the parties to it and their respective successors and
permitted assigns, nor is anything in this Agreement intended to relieve or
discharge the obligation or liability of any third persons to any party to this
Agreement, nor shall any provision give any third persons any right of
subrogation or action against any party to this Agreement.

         16.2    Assignment.  This Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and permitted
assigns.  Neither this Agreement nor any of the rights, interests and
obligations hereunder shall be assigned by any of the parties hereto without
the prior written consent of each of the other parties hereto, which consent
shall not be unreasonably withheld.


17.      TERMINATION AND REMEDIES.

         17.1    Termination.  Anything in this Agreement to the contrary
notwithstanding:

         (a)     Mutual Consent.  This Agreement may be terminated by the
mutual consent of the CML Companies and Schott.

         (b)     Default.  In the event that a party hereto shall, contrary to
the terms of this Agreement, intentionally fail or refuse to consummate the
transactions contemplated hereby or to take any other action referred to herein
necessary to consummate the transactions contemplated hereby, then the
nondefaulting party, after affording the defaulting party a ten (10) day period
after notice in which to cure, shall have the right, in addition to the other
rights specified in Section 17.2 below, to terminate this Agreement by written
notice given to the other parties hereto.

         (c)     Upset Date.  In the event that the Closing Date shall not have
occurred on or prior to March 31, 1997 then, unless otherwise agreed to in
writing by Schott and CML, this Agreement shall terminate on or following such
date (as such date may be postponed pursuant hereto), and upon written notice
given by Schott to CML, or by CML to Schott, provided that if the absence of
such occurrence shall be due to the intentional failure or refusal of Schott or
CML to perform their respective obligations hereunder or to take any other
action referred to herein necessary to consummate the transactions contemplated
hereby, then, in the case of a default by 



<PAGE>   35

                                   - 35 -


Schott, Schott shall not have the right, and in the case of a default by such
CML, such CML shall not have the right, to terminate the Agreement pursuant to
this Section 17.1(c).

         (d)     Legal Restraint.  Either Schott or CML may, by written notice
to the other, terminate this Agreement if at the time the written notice of
termination is given, there is in effect a final and non-appealable permanent
injunction enjoining the sale, transfer or delivery of any of the Units or a
final order of any governmental agency prohibiting such sale or transfer.

         17.2    Remedies.

         (a)     Damages.  If this Agreement is terminated because of a
material breach of this Agreement by any of the CML Companies, on the one hand,
or Schott, on the other, then the nonbreaching party shall have the right to
sue the other for damages including all reasonable costs and expenses
(including reasonable attorneys' fees) theretofore actually suffered and
sustained by the nondefaulting party.

         (b)     Effect of Termination.  Except as set forth in Section 17.2(a)
above, any termination of this Agreement shall have the effect of causing this
Agreement to thereupon become void and of no further force or effect
whatsoever, and thereupon no party hereto will have any rights, duties,
liabilities or obligations of any kind or nature whatsoever against any other
party hereto based upon either this Agreement or the transactions contemplated
hereby, except in each case the obligations of any party for its own expenses
incurred in connection with the transactions contemplated by this Agreement and
the obligations of any party with respect to confidentiality.

18.      SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

         The representations, warranties, opinions or other writings provided
for in the covenants and agreements of the respective parties before the
Closing Date shall be deemed to be continuing and shall survive the Closing
Date for a period of two (2) years, except for the representations and
warranties included in Sections 2.1, 2.3, 2.5, 2.6, 2.8, 3.1, 3.2, 3.3, 3.4,

         CML hereby unconditionally and absolutely guarantees the performance
of the covenants and agreements of CML, CML Fiberoptics and Electro in this
Agreement and the truth and accuracy of the representations and warranties
herein.  Schott shall not be required to proceed against any other party before

22.      PUBLICITY.

         CML and Schott acknowledge their mutual desire, and shall endeavor, to

such disclosure by any party as may be necessary in order to comply with
applicable requirements of United States federal and state laws and regulations
and similar applicable laws and regulations of the Federal Republic of Germany.
Any party issuing a press release with respect to the transactions contemplated
hereby shall first obtain the consent of the other parties, which consent shall
not be unreasonably withheld or delayed.

23.      GOVERNING LAW.

         This Agreement shall be construed in accordance with, and governed by,
the laws of The Commonwealth of Massachusetts, without giving effect to rules
governing choice of law.  CML, CML Fiberoptics and Electro on the one hand,

related to this Agreement or the Limited Liability Company Agreement or the
Transfer Agreement and CML, CML Fiberoptics and Electro, on the one hand, and

forum to the maintenance of such action or proceeding.  CML, CML Fiberoptics
and Electro hereby irrevocably appoint Ronald

Goldstein, with a copy to David Engel at the address set forth in Section 20

"Schott Process Agent"), as their respective agents to receive on their behalf
service of copies of the summons and complaint and any other process which may

Electro in care of the CML Process Agent at the CML Process Agent's above
address, and in the case of Schott, in care of the Schott Process Agent at the
Schott Process Agent's above address.  CML, CML Fiberoptics and Electro each
hereby irrevocably authorizes and directs the CML Process Agent to accept such
service on its behalf and Schott hereby irrevocably authorizes and directs the
Schott Process Agent to accept such service on its behalf.  As an alternative
method of service, CML, CML Fiberoptics and Electro on the one hand, and Schott,
on the other hand, also irrevocably consent to the service of any and all
process in any such action or proceeding by the mailing of copies of such
process to CML or to Schott, as the case may be, at its address specified in
Section 20 hereof. CML, CML Fiberoptics and Electro, on the one hand, and
Schott, on the other hand, each agrees that a final judgment in any such action
or proceeding, all appeals having been taken or the time period for such appeals
having expired, shall be conclusive and may be enforced in other jurisdictions
by suit on the judgment or in any other manner provided by law.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed as a sealed instrument as of the day and year first above
written.

     4.9 Company Strategy and Major Decisions.

     (a) The Company's initial Strategic Plan is as follows:

     The Company shall operate primarily in the "light guide"-based fiberoptics
business (the "Business"). The Members and the Company desire to grow the
Business of the Company to take advantage of its business opportunities. Schott
operates a broad range of glass-related businesses, including in several areas
of fiberoptics, such as "imaging" and "light guide." Electro and its affiliates
(including Chicago Miniature Lamp, Inc., hereinafter sometimes referred to
together with Electro as "CML") operate in lighting businesses. Schott and its
affiliates (other than Hoya-Schott Corporation) and CML and its affiliates will
cooperate to advance the Company's prospects and will support the Company to
the best of their abilities to maximize the profits of the Company. The Company
shall operate in a manner that maximizes the Company's growth and long-term
profitability and takes advantage of its business opportunities, with a primary
focus on the North American markets.

     The Company, Schott and CML will establish regular communication and
cooperation among themselves and their affiliates. The Company will draw on the
resources of the Members, and the Members will make available their general
resources, such as cash management, human resources, accounting, legal and the
like. There will be no intercompany charges for internal costs incurred in
connection with such communication and cooperation. Appropriate charges/prices
will be worked out among the parties for other types of cooperative endeavors.

     The light guide-based operations of Schott Glaswerke - GB Faser Optik,
located in Wiesbaden and Schott Fibre Optics (U.K.), Ltd. (such light
guide-based operations sometimes being referred to as "EE"), affiliates of
Schott, will handle their existing North American business through the Company
and, unless otherwise agreed, initially on a commission basis (probably
through September 1997). Any new North American business (customers) of EE will
be referred to the Company. Existing North American business (customers) of EE
will be continued by EE through the Company on a commission basis until an
appropriate means of more complete transfer can be worked out. (EE's KL range
of cold light sources/light guides -- used primarily in microscopy -will not be
included in the business being referred to the Company.) EE will be available
to provide sales assistance to the Company in Europe. Schott and EE offer their
other resources to the Company on commercially reasonable terms. Schott and CML
shall engage in transactions with the Company on terms at least as favorable as
they provide to any third parties in transactions of comparable subject and
scope. Schott and CML will provide the Company with reasonable access to
research and development information so long as the provision of such
information does not result in additional cost to the party providing the
information and so long as such access does not violate the terms of any
agreement between either Schott or CML and a third party. The Company will make
its decisions with respect to whether to manufacture or purchase products and
components in a manner that maximizes the Company's profitability.

     The continuation by Schott and its affiliates of their businesses,

by the Board of Directors.

     (c) The Company will endeavor to maintain a debt-to-equity ratio of

              ALLOCATIONS OF PROFITS, LOSSES, ETC.; DISTRIBUTIONS

     6.1 Allocations of Income, Losses, Etc. A Member's distributive share of
income, gain, loss, deduction or credit (or items thereof) as shown on the
annual federal income tax return prepared by the Company's accountants or as
finally determined by the Internal Revenue Service or the courts, and as
modified by the capital accounting rules of section 704(b) of the Code and the
regulations thereunder as implemented by Article 6 hereof, as applicable, shall
be determined as provided in this Article 6.

     (a) Solely for tax purposes, in determining each Member's allocable share
of the taxable income or loss of the Company, depreciation, depletion,
amortization and gain or loss with respect to any contributed property, or with
respect to revalued property where Company property is revalued pursuant to
paragraph (b)(2)(iv)(f) of section 1.704-1 of the Income Tax Regulations, shall
be allocated to the Members under the traditional method as provided in Section
1.704-3(b) of the Income Tax Regulations.

     (b) Notwithstanding anything to the contrary in this Article 6, if there
is a net 



                                      14

decrease in "Partnership Minimum Gain" or "Partner Nonrecourse Debt Minimum
Gain" (as such terms are defined in sections 1.704-2(b) and 1.704-2(i)(2),
respectively, of the Income Tax Regulations) during a Company taxable year,
then each Member shall be allocated items of Company income and gain for such
year (and, if necessary, for subsequent years), to the extent required by, and
in the manner provided in, section 1.704-2 of the Income Tax Regulations. This
provision is intended to be a "minimum gain chargeback" within the meaning of
sections 1.704-2(f) and 1.704-2(i)(4) of the Income Tax Regulations and shall
be interpreted and implemented as therein provided.

     (c) Subject to the provisions of Section 6.1(b), but otherwise
notwithstanding anything to the contrary in this Article 6, if any Member's
capital account has a deficit balance in excess of such Member's obligation to
restore its capital account balance, computed in accordance with the rules of
paragraph (b)(2)(ii)(d) of section 1.704-1 of the Income Tax Regulations
(including such Member's share of Partnership Minimum Gain and Partner
Nonrecourse Debt Minimum Gain as provided in sections 1.704-2(g) and
1.704-2(i)(5) of the Income Tax Regulations), then sufficient amounts of gross
income and gain (consisting of a pro rata portion of each item of Company gross
income and gain for such year) shall be allocated to such Member in an amount
and manner sufficient to eliminate such deficit as quickly as possible. This
provision is intended to be a "qualified income offset" within the meaning of
section 1.704-l(b)(2)(ii)(d) of the Income Tax Regulations and shall be
interpreted and implemented as therein provided.

     (d) Except as provided in Sections 6.1(e) and (f) hereof or as otherwise
required by law, if any Units are transferred during any taxable year, all
items to be allocated to the Members for such entire taxable year shall be
prorated on the basis of the portion of such taxable year which precedes each
such change and the portion of such taxable year on and after each such change
according to the number of days in each such portion, and the items so
allocated for each such portion shall be allocated to the Members in the manner
in which such items are allocated as provided in this Article 6 during each
such portion of the taxable year in question.

     (e) Any special allocation of income or gain pursuant to Section 6.1(b) or
6.1(c) hereof shall be taken into account in computing subsequent allocations
of income and gain pursuant to this Article 6 so that the net amount of all
such allocations to each Member shall, to the extent possible, be equal to the
net amount that would have been allocated to each such Member pursuant to the
provisions of this Article 6 if such special allocations of income or gain
under Section 6.1(c) hereof had not occurred.

     (f) Losses.


          i)   Items of deduction and loss attributable to recourse liabilities
     of the Company (within the meaning of section 1.752-1(a)(1) of the Income
     Tax Regulations, but excluding "Partner Nonrecourse Debt" within the
     meaning of section 1.704-2(b)(4) of the Income Tax Regulations) shall be
     allocated among the Members in accordance 



                                      15
<PAGE>   57

     with the ratio in which the Members share the economic risk of loss
     (within the meaning of section 1.752-2 of the Income Tax Regulations) for
     such liabilities.

          ii)  Items of deduction and loss attributable to "Partner Nonrecourse
     Debt" within the meaning of section 1.704-2(b)(4) of the Income Tax
     Regulations shall be allocated to the Members bearing the economic risk of
     loss with respect to such debt in accordance with section 1.704-2(i) of
     the Income Tax Regulations.

          iii) Items of deduction and loss attributable to the Company's
     "Nonrecourse Liabilities" within the meaning of section 1.704-2(b)(3) of
     the Income Tax Regulations shall be allocated among the Members
     proportionately in accordance with their ownership of Units to the extent
     permitted by law.

          iv)  All other items of operating net loss ("Net Loss") shall be
     allocated among the Members, proportionately in accordance with their
     ownership of Units, except that Net Loss shall not be allocated to any
     Member to the extent it would create a deficit balance in excess of such
     Member's obligation to restore its capital account balance, computed in
     accordance with the rules of Section 1.704-1(b)(2)(ii)(d) of the Income
     Tax Regulations (including such Member's share of Partnership Minimum Gain
     and Partner Nonrecourse Debt Minimum Gain as provided in sections
     1.704-2(g) and 1.704-2(i)(5) of the Income Tax Regulations). Any Net Loss
     which cannot be allocated to a Member because of the limitation set forth
     in the previous sentence shall be allocated first to the other Members to
     the extent such other Members would not be subject to such limitation and
     second any remaining amount to the Members in the manner required by the
     Code and the Income Tax Regulations.

     (g) Subject to the provisions of Sections 6.1(b) through (f), items of
income and gain shall be allocated to the Members in the following priority:

          i)   First, if allocations of Net Loss have been made to the Members
     under Section 6.1(f)(iv), then in the amount of, and proportionate to, the
     amount of such Net Loss.

          ii)  Second, to those Members who have had items of loss or deduction
     allocated to them under Section 6.1(f)(i), in the amount of, and
     proportionate to, the amount of such items of loss or deduction.

          iii) Third, the balance among the Members in proportion to their
     ownership of Units.

     6.2 Conformity of Reporting. The Members hereby agree to be bound by the
provisions of this Article 6 in reporting their shares of Company income, loss,
credits and other items for income tax purposes.

<PAGE>   59

     (c) To the fullest extent permitted by law, the Company shall indemnify

fiscal year, the Company shall, in a timely manner, prepare and mail, or cause
its accountants to prepare and mail, to each Member and, to the extent

respect to such Member's interest in the Company hereby, to the fullest extent
permitted by law, indemnifies and agrees to hold harmless the Members and the
Company for such excess amount or such withholding requirement, as the case may
be.

                      TRANSFER AND ASSIGNMENT OF INTERESTS
                   RESOLUTION OF DISPUTES; ADDITIONAL CAPITAL

     8.1 Restrictions on Issuance of New Units. The Company shall not issue
further Units without the approval of both Members. The Members agree, for so
long as both are Members of the Company, to exercise their powers as Members
and to direct the Directors of the Company to assure that the Company shall not
issue any further Units except as expressly agreed in writing by both Members

     8.2 Restrictions on Transfer. No Member may Transfer any Units which he or
it may hold unless such Units are Transferred (i) in a Permitted Transfer; or
(ii) in a Transfer made in compliance with the provisions of Section 8.3, if
applicable, Section 8.4, if applicable, and the provisions of Section 8.5
hereof.

     8.3 Deadlock Provisions.

     (a) In the event of a deadlock of the Board of Directors, at two
consecutive meetings, with respect to the Strategic Plan or another matter
that, as a result of such deadlock, threatens to have a materially adverse
effect on the financial condition or operations of the Company, including
matters relating to the Strategic Plan or Section 3.3 (b), each Member, acting
through its Chief Executive Officer or other designated representative, shall
consult in good faith during the period of 120 days following the second such
Board of Directors meeting (the "Consultation Period") in an effort to resolve
the deadlock. The Consultation Period may be extended by mutual consent of the
Members, and the Members may submit the dispute to binding arbitration if they
so elect. If no agreement has been reached between the Members with respect to
the dispute within 30 days after the end of the Consultation Period, the
Members shall endeavor to negotiate the purchase by one Member or all of the
Units of the other Member. In the event that the Members are unable to
negotiate an acceptable arrangement with respect to such a purchase of Units,
either party may make the offer described in paragraph 8.3(b)

     (b) Either Member shall have the right to offer in writing to either buy
all of the Units of the other Member or sell all of its Units to the other
Member at the price per Unit and on the terms stated by the offering Member in
his written offer (the "Offered Price and Terms"). The other Member shall,
within ninety (90) days of the receipt of the written offer from the offering
Member, either agree to buy the offered Units at the Offered Price and Terms or
agree to sell all of its own Units to the offering Member at the Offered Price
and Terms. The other 



                                      19
<PAGE>   61

Member shall notify the offering Member of such election in writing and the
offering Member shall be bound by such election. In the event that the other
Member fails to elect in writing within such 90 day period either to buy or
sell, the other Member shall be deemed to have entered into a binding contract
to either sell its Units to the Offering Member or buy the Units of the
Offering Member, in either case at the Offered Price and Terms, as the Offering
Member shall elect.

     (c) Closing. The payment of the purchase price and the Transfer of the
Units shall occur within sixty (60) days after the end of the 90 day period
described in paragraph 8.3(b). Upon the payment of the purchase price, the
purchased Units shall be deemed to have been transferred to the purchaser by
the seller without the need for further action by the parties.

     8.4 Members' Parallel Exit Rights.

     (a) Transfers by One Member. In the event that a Member proposes to
Transfer Units other than in a Permitted Transfer, then prior to any such
Transfer, the Member proposing such Transfer (the "Selling Member") shall give
notice of such proposed Transfer to the other Member, which notice shall set
forth (i) the number and class of Units proposed for Transfer; (ii) a
description of the proposed Transfer; (iii) the name and address of each bona
fide prospective purchaser including, in the case of any prospective purchaser
who is not an individual, the names and addresses of the individuals directly
or indirectly controlling such prospective purchaser; and (iv) all other
material terms of the proposed Transfer, including without limitation, the
purchase price and the manner in which such purchase price is proposed to be
paid (such notice is hereinafter referred to as the "Offer").

     (b) Election to Participate. Within sixty (60) days of receipt of the
Offer given pursuant to Section 8.4(a) hereof, the other Member may elect (in
the event that the other Member does not exercise its rights under Section 8.5
hereof), by written notice to the Selling Member, to participate on a pro rata
basis in such Transfer. The other Member may Transfer that number of Units
which bears the same proportion to the aggregate number of Units held by the
other Member as the number of Units proposed for Transfer by the Selling Member
bears to the aggregate number of Units which the Selling Member then holds. In
the event that the other Member elects to participate in a Transfer pursuant to
this Section 8.4(b), the other Member shall be entitled to receive from the
proposed purchaser of the Units written confirmation that such proposed
purchaser is prepared to purchase the Selling Member's Units on the terms
described to the other Member in the Offer and no Transfer may proceed unless
and until such prospective purchaser provides such confirmation to the other
Member making such an election.

     8.5 Right of First Refusal.

     (a) Offer. In the event that either Member proposes to Transfer Units
other than in a Permitted Transfer, then, prior to any such Transfer, such
Member (the "Selling Member") shall offer such Units to the other Member by
delivery of the Offer described in Section 8.4. 



                                      20
<PAGE>   62

Such Offer shall constitute an irrevocable offer to sell such Units to the
other Member either (a) on the terms and conditions set forth in the Offer or
(b) on the terms and conditions determined pursuant to Section 8.5( c), below,
until the earlier of (i) the date on which all of the Offered Units are
accepted by the other Member as provided in Section 8.5(b) hereof or (ii) sixty
(60) days following the Offer Date (as defined in Section 8.5(b)).

     (b) Election by the Other Member. Within sixty (60) days after the receipt
of the notice by the other Member (which date of receipt shall be deemed to be
three (3) days after the date of hand delivery or mailing and is referred to as
the "Offer Date"), the other Member may elect to purchase all of the Offered
Units by delivering a written notice as described above.

     (c) Formula-Based Purchase Price. As an alternative to electing to
purchase the offered Units on the terms and conditions set forth in the Offer,
the other Member shall have the right to elect to purchase the offered Units at
a cash purchase price per Unit determined as follows:

     (i) The value of the Company would be established by multiplying the
average annual earnings, before interest and taxes, of the Company during the
previous three complete fiscal years (or such lesser period as the Company
shall have been in existence) by six (6).

    (ii) The value so determined would be divided by the total number of
issued and outstanding Units.

     (d) Condition to Effective Election. Notwithstanding the provisions of
Section 8.5(b) hereof, no election to purchase Offered Units shall be effective
unless the election has been made under Section 8.5(b) to purchase, in the
aggregate, all and not less than all of the Offered Units.

     (e) Non-Cash Offers. Should any Offer contain terms by which the Offered
Units are to be Transferred for consideration other than cash or cash
equivalents, then the cash value of such Offer shall be determined by an
independent investment banking firm of national standing and reputation to be
jointly selected by the Selling Member and the other Member. The other Member
shall have the opportunity to accept such Offer as provided in Section 8.5(b)
at the cash value so determined. The costs and expenses of such investment
banking firm shall be borne by the Selling Member.

     (f) Price and Terms of Acceptance. The other Member shall pay either the
purchase price set forth in the Offer at its cash value as determined pursuant
to Section 8.5(e) or the purchase price determined pursuant to Section 8.5(c).
At the closing of such purchase, which shall take place within sixty (60) days
after the later of the other Member's election to purchase the Units or the
determination of the purchase price under Section 8.5(e), the other Member
shall deliver the consideration for such Offered Units and the Selling Member
shall 



                                      21
<PAGE>   63

be deemed to have delivered to the other Member the Offered Units without
further action.

     (g) Rights to Transfer Following an Offer. If the Offered Units are not
purchased by the other Member pursuant to the foregoing provisions of this
Section 8.5, the Selling Member may Transfer such Offered Units to the
Transferee upon the Terms set forth in the Offer. Any Units so Transferred will
thereafter be subject to all restrictions or obligations set forth in this
Agreement. If the Selling Member fails to make any such Transfer within ninety
(90) days after the Offer Date, such Offered Units shall again become subject
to all of the restrictions of this Agreement. If, in the course of negotiations
with a prospective Transferee, terms are agreed upon which are more favorable
to the prospective Transferee than the Terms described in the Offer, the
Selling Member shall not Transfer such Offered Units without first submitting
another Offer to the other Member which shall set forth such new Terms, and the
other Member shall have the right to accept such Offer in accordance with this
Section 8.5.

     8.6 Bankruptcy or Change of Control of Member.

     (a) Offer. In the event that a Member becomes Bankrupt (as defined in
Section 8.6(b)) or undergoes a Change of Control (as defined in Section
8.6(c)), such Member shall be deemed to have made an irrevocable offer to sell
all of such Member's Units to the other Member at the price per Unit determined
pursuant to Section 8.5(c).

     (b) Bankrupt. For purposes of this Section 8.6, a Member shall be deemed
"Bankrupt" in the event of the adjudication of the Member as a bankrupt or
insolvent, or entry of an order, remaining unstayed by appeal or otherwise for
thirty (30) days, appointing a receiver or trustee for the Member, or for all
or any of its property, or approving a petition seeking reorganization or other
similar relief under the bankruptcy or other similar laws of the United States
or of any state or of any other competent jurisdiction; or the filing by the
Member of a petition seeking any of the foregoing or consenting thereto, or the
filing of a petition to take advantage of any debtors' act, or making a general
assignment for the benefit of creditors, or admitting in writing its inability
to pay its debts as they mature; or the filing of an involuntary petition with
respect to the Member seeking relief under the bankruptcy or similar laws of
the United States or of any state or any other competent jurisdiction, which
petition is not dismissed within sixty (60) days.

     (c) Change of Control. A "Change of Control" shall be deemed to have
occurred with respect to a Member in the event that: (i) a Member effects a
consolidation or merger with another limited liability company or corporation
(other than a consolidation or merger in which such Member is the continuing
Company or a consolidation or merger with an Affiliate); or (ii) fifty percent
(50%) or more of the outstanding shares of capital stock of the Member are
acquired by one person or an affiliated group of persons who are not currently

Member's first actual knowledge of the Bankruptcy or Change of Control), the
other Member may elect to purchase all of the Offered Units by delivering a
written notice as described above.

     (e) Closing. The payment of the purchase price and the Transfer of the
Units shall occur within sixty (60) days after the other Member's election to
purchase.

     8.7 Permitted Transferees; Option. For purposes of Sections 8.3 through
8.6, a Permitted Transferee holding Units transferred by a Member shall be
deemed to participate with the Member in the processes set forth in such
sections, and the Member shall be deemed to have an irrevocable power of
attorney, coupled with an interest, to act on behalf of its Permitted
Transferees for purposes of such sections. In the event that Schott sells all
of its Units pursuant to the provisions of any of Sections 8.3 through 8.6 and,
at the time of such sale Schott continues to hold its Option, the Option shall
be included as part of the Units sold and Schott shall receive payment of the

sale.

                                   ARTICLE 9

                          DISSOLUTION AND LIQUIDATION

Affiliates who are creditors, in satisfaction of liabilities of the Company in

dissolution and winding up of the affairs of the Company (including, without

Agreement and the Act); and

or trustees.

                                   ARTICLE 10

              INDEMNIFICATION AND EXCULPATION; CERTAIN AGREEMENTS

     10.1 Indemnification of the Members. The Company shall indemnify, hold
harmless and place in funds the Members, the Directors, their respective
Affiliates, and their respective agents and/or the legal representatives of any
of them, and each other Person who may incur liability as a Member or otherwise
in connection with the management or ownership of the Company (each, an
"Indemnified Party"), against all liabilities and expenses (including amounts
paid in satisfaction of judgments, in compromise, as fines and penalties, and
as counsel fees) reasonably incurred by him, her or it in connection with the
investigation, defense or disposition of any action, suit or other proceeding,
whether civil or criminal (a "Proceeding"), in which any Indemnified Party may
be involved or with which he, she or it may be threatened, while a Member or
serving in such other capacity or thereafter, by reason of him, her or it being
or having been a Member, or by serving in such other capacity, except with
respect to any matter which constitutes willful misconduct, bad faith, gross
negligence or reckless disregard of the duties of his office, or criminal
intent. The Company shall have the right to approve any counsel selected by any
Indemnified Party and to approve the terms of any proposed settlement. The
rights accruing to a Member and each other Indemnified Party under this Section
10.1 shall not exclude any other right to which he, she or they may be lawfully
entitled; provided that any right of indemnity or reimbursement granted in this
Section 10.1 or to which any Indemnified Party may be otherwise entitled may
only be satisfied out of the assets of the Company, and no Member shall be
personally liable with respect to any such claim for indemnity or
reimbursement. Notwithstanding any of the foregoing to the contrary, the
provisions of this Section 10.1 shall not be construed so as to provide for the
indemnification of a Member or any other Indemnified Party for any liability to
the extent (but only to the extent) that such indemnification would be in
violation of applicable law or such liability may not be waived, modified or
limited under applicable law, but shall be construed so as to effectuate the
provisions of this Section 10.1 to the fullest extent permitted by law. The
right to indemnification conferred in this Article 10 shall be a contract right
and shall include the right to be paid by the Company the expenses (including
reasonable attorneys' fees) incurred in defending any Proceeding in advance of
its final disposition (an "Advancement of Expenses"); provided, however, that,
if Delaware law so requires, an Advancement of Expenses incurred by an
Indemnified Party shall be made only upon delivery to the Company of an
undertaking (an "Undertaking"), by or on behalf of such Indemnified Party, to
repay all amounts so advanced if it shall ultimately be determined by final
judicial decision from which there is no further right to appeal that such
Indemnified Party is not 



                                      24

<PAGE>   66

entitled to be indemnified for such expenses under Article 10.

     10.2 Reimbursement and Indemnity. If a Member shall, pursuant to
authorization of or approval by the Board or a final judgment of a court of
competent jurisdiction or in compliance with law or order of any governmental
agency, pay any amount on behalf of or for the account of the Company with
respect to any liability, obligation, undertaking, damage, or claim for which
the Company shall or may, pursuant to contract or applicable law, be liable or
responsible, or with respect to making good any loss or damage sustained by, or
paying any duty, cost, claim, or damage incurred by, the Company, then the
Company shall reimburse such Member for such amount as shall have been so paid
by such Member.

     10.3 Right of Indemnified Party to Bring Suit. If a claim under Section
10.1 hereof is not paid in full by the Company within sixty days after a
written claim has been received by the Company, except in the case of a claim
for an Advancement of Expenses, in which case the applicable period shall be
thirty days, the Indemnified Party may at any time thereafter bring suit
against the Company to recover the unpaid amount of the claim. If successful in
whole or in part in any such suit, or in a suit brought by the Company to
recover an Advancement of Expenses pursuant to the terms of an Undertaking, the
Indemnified Party shall be entitled to be paid also the expense of prosecuting
or defending such suit. In (i) any suit brought by the Indemnified Party to
enforce a right to indemnification hereunder (but not in a suit brought by the
Indemnified Party to enforce a right to an Advancement of Expenses) it shall be
a defense that, and (ii) in any suit by the Company to recover an Advancement
of Expenses pursuant to the terms of an Undertaking the Company shall be
entitled to recover such expenses upon a final adjudication that, the
Indemnified Party has not met the applicable standard of conduct set forth in
Delaware law. Neither the failure of the Company (including its board of
directors, independent legal counsel, or its Members) to have made a
determination prior to the commencement of such suit that indemnification of
the Indemnified Party is proper in the circumstances because the Indemnified
Party has met the applicable standard of conduct set forth in Delaware law, nor
an actual determination by the Company (including its board of directors,
independent legal counsel, or its Members ) that the Indemnified Party has not
met such applicable standard of conduct, shall create a presumption that the
Indemnified Party has not met the applicable standard of conduct or, in the
case of such a suit brought by the Indemnified Party to enforce a right to
indemnification or to an Advancement of Expenses hereunder, or by the Company
to recover an Advancement of Expenses pursuant to the terms of an Undertaking,
the burden of proving that the Indemnified Party is not entitled to be
indemnified, or to such Advancement of Expenses, under this Article 10 or
otherwise shall be on the Company.

     10.4 Exculpation. No Director, officer, Company employee, Member or
Affiliate thereof or their respective agents and/or the legal representatives
of any of them shall be liable to any Member or the Company for mistakes of
judgment or for action or inaction which such Person reasonably believed to be
in or not opposed to the best interests of the Company unless such action or
inaction constitutes willful misconduct, bad faith, gross negligence or
reckless disregard of his or its duties and, with respect to any criminal
action, such party reasonably 



                                      25

<PAGE>   67

believes his conduct was lawful. Each Member may (on its own behalf or on the
behalf of any Representative, any Affiliates of such Member or their respective
agents and/or legal representatives of any of them), consult with counsel,
accountants and other experts in respect of the Company's affairs and such
Person shall be fully protected and justified in any action or inaction which
is taken in accordance with the advice or opinion of such counsel, accountants
or other experts; provided that they shall have been selected with reasonable
care. Notwithstanding any of the foregoing to the contrary, the provisions of
this Section 10.4 shall not be construed so as to relieve (or attempt to
relieve) a Member or any other Person of any liability, to the extent (but only
to the extent) that such liability may not be waived, modified or limited under
applicable law, but shall be construed so as to effectuate the provisions of
this Section 10.4 to the fullest extent permitted by law.

     10.5 Joint Venture Formation Agreement. Nothing contained in Sections
10.1, 10.2, 10.3 or 10.4 of this Agreement shall be deemed to modify or
supersede the obligations of the parties to the Joint Venture Formation
Agreement and, in the event of a conflict between any provisions of the Joint
Venture Formation Agreement and any provisions of Sections 10.1, 10.2, 10.3 or
10.4 of this Agreement, the provisions of the Joint Venture Formation Agreement
shall control.
