                              CAPITAL CONTRIBUTIONS

     Section  3.01  Initial  Contributions.  (a)(i)  Upon  and  subject  to  the
conditions in section 4.03 of this Agreement being  fulfilled or waived,  GE and
Emcore  shall each be  obligated  to make an initial  cash  contribution  to the
capital of the Company of *** and ***,  respectively,  such that the  respective
initial  Capital  Accounts  of GE and Emcore will equal 51% and 49% of the total
capital of the Company.  The initial Membership  Interests of GE and Emcore will
be 51%  and  49%,  respectively.  GE  shall  contribute  ***  and  Emcore  shall
contribute  *** of its initial  capital  contribution  at the  Closing,  and the
balance of their respective initial capital  contributions  shall be made in one
or more installments  promptly after the Company,  acting through its President,
has submitted and has gained approval of an Annual Operating Plan that indicates
that  such  balance  is to be made;  provided,  however,  that  notice  for such
contribution  of such  balance  shall not be given  prior to ***  following  the
Closing Date (as hereinafter defined).

     (ii) GE shall make a convertible  loan to Emcore in the original  principal
amount of $7,800,000,  the proceeds of which shall be used by Emcore to make its
initial capital contribution referred to in subsection 3.01(a)(i) above (the "GE
Loan"). The GE Loan shall be evidenced by a mutually acceptable  definitive loan
agreement to be executed and delivered by GE and Emcore on or before the Closing
Date  (the  "GE  Loan  Agreement").  The GE Loan  Agreement  shall  contain  (A)
customary  representations  and warranties on the part of Emcore,  (B) customary
affirmative and negative  covenants  relating to Emcore and its business and (C)
the general terms set forth on Schedule 3.01(a)(ii) attached hereto.

     (b)(i) In the event that Emcore fails to contribute all or a portion of the
balance  of its  initial  capital  contribution  at the  times  required  and as
described  in  section  3.01(a)  above,  GE shall  have the  right  (but not the
obligation)  to increase its  contribution  to the extent that Emcore  failed to
contribute the balance of its initial capital contribution (any such increase in
contribution  shall be referred to as a "MI  Increase").  Upon completion of any
such capital  contribution,  and subject to subsection  3.01(b)(ii)  below,  the
Membership  Interests  of  the  Members  shall  be  adjusted  to  reflect  their
respective  actual  capital  contributions  to  the  Company  as of  such  date;
provided,  however, that for purposes of the Required Interest for Supermajority
Transactions  under section 7.03 hereof,  prior to the  expiration of the option
period in subsection  3.01(b)(ii) below,  Emcore's Membership Interest shall not
be deemed to have fallen below 34% of the outstanding  Membership Interests as a
result of any failure by Emcore to contribute all or a portion of the balance of
its  initial  capital  contribution  at the times and as  described  in  section
3.01(a) above.

     (ii) GE agrees that in the event that it receives a MI Increase as provided
in subsection  3.01(b)(i) above, Emcore shall have the option to purchase all or
a part of that MI Increase for

REQUEST.  REDACTED  MATERIAL IS MARKED WITH A *** AND HAS BEEN FILED  SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION.

cash at a price  equal to the amount  contributed  by GE for such MI Increase or
portion thereof,  plus interest at a then prevailing  market rate reflecting the
nature of the investment.  Emcore must exercise the option by delivering written
notice to GE at least  thirty (30) days prior to the first  anniversary  date of
the capital contribution giving rise to the MI Increase.  Any such option notice
shall set a date for the consummation of the transaction, which date shall be no
later than  thirty (30) days after the date of the option  notice.  In the event
that Emcore fails to timely  exercise the option and  consummate the purchase of
the MI Increase or portion  thereof  indicated in the option notice,  the option
shall  expire and be of no force or effect and the  Membership  Interests  shall
remain as adjusted  pursuant to subsection  3.01(b)(i)  above.  Neither Emcore's
failure to contribute  all or any portion of the balance of its initial  capital
contribution at the times required and as described in section 3.01(a) above nor
Emcore's  failure to timely  exercise the option and  consummate the purchase of
the MI  Increase  or  portion  thereof  indicated  in the  option  notice  shall
constitute a breach of this Agreement by Emcore.

     (iii) Upon the purchase by Emcore of a MI Increase or portion  thereof from
GE, the  Membership  Interests of the Members  shall be adjusted to reflect such
purchase  (excluding  any interest  paid as provided in  subsection  3.01(b)(ii)
above).

     Section  3.02  Additional  Capital.  (a) Any increase in the capital of the
Company  shall  constitute a  Supermajority  Transaction.  Both Members shall be
entitled to participate in any capital  increase pro rata in proportion to their
respective then existing Membership  Interests.  In the event that either Member
fails to so participate in a capital  increase,  the other Member shall have the
right (but not the obligation) to increase its  participation to the extent that
the other Member  failed to  participate.  Upon  completion  of any such capital
increase,  the Membership  Interests of the Members shall be adjusted to reflect
their respective  actual  participations  therein.  The Members agree that it is
their  present  intent to not  increase  the capital of the  Company  beyond the
initial *** before ***.

     (b) In the event that  further  capital is required by the Company in order
to meet any obligation or pay any liability of the Company, the Company, subject
to section  7.03,  may borrow such  required  capital from any Person or entity,
including  any  Member  or any  Affiliate  of a  Member,  on  such  commercially
reasonable  terms as the Committee  may  determine;  provided,  that the Company
shall offer to the Members the  opportunity  to lend or  otherwise  provide such
funds  (other than as capital  contributions)  on such  commercially  reasonable
terms,  pro rata in  proportion to their  respective  Membership  Interests,  or
otherwise as may be agreed to.

     (c) In the event  that the  Members  approve  an  increase  in  capital  as
provided in section  3.02(a) of this  Agreement and to the extent Emcore in good
faith determines that it has  insufficient  resources to permit it to contribute
the full amount of its  proportionate  share of such increase,  GEL shall assist
Emcore in  raising  capital to  participate  in such  increase  to the extent of
Emcore's  insufficiency of resources which  assistance will include,  but not be
limited to (i) representing  Emcore to GE Capital for an equity investment or an
asset backed loan by GE 




Capital or (ii) making a short-term  non-recourse  loan to Emcore (a "Short-Term
Loan"), the term of which shall not exceed twelve months,  beginning on the date
that all or any  portion  of the  additional  capital  raised by the  Company is
initially  invested or used by the Company,  on commercially  reasonable  terms,
including a market rate of interest that  reflects the nature of the  investment
or use of funds by the  Company.  Each  Short-Term  Loan  shall be  secured by a
pledge of  Emcore's  Membership  Interest  pursuant  to the Pledge and  Security
Agreement in the form of Exhibit C hereto (a "Pledge  Agreement").  In the event
that  Emcore is unable to repay to GEL all unpaid  principal  and  interest on a
Short-Term Loan when due, then the Membership  Interests of the Members shall be
adjusted so that such unpaid principal and interest of such loan will be treated
under section  3.02(a) of this  Agreement as a capital  increase in which Emcore
failed to participate and with respect to which GEL increased its  participation
to the extent of such failure by Emcore.

     Section 3.03 Return of  Contributions.  No Member is entitled to the return
of any part of its Capital Contributions or to interest in respect of either its
Capital Account or its Capital Contributions. An unreturned Capital Contribution
is not a liability of the Company or of any Member.

     Section  3.04  Warrants.  On the  Closing  Date,  Emcore  shall issue to GE
warrants  to  purchase  Emcore  common  stock,  no par  value,  on the terms and
conditions set forth on Schedule 3.04 hereto (the "Emcore Warrants"). The Emcore
Warrants  shall  be  evidenced  by  a  mutually  acceptable  definitive  warrant
agreement to be executed and delivered by GE and Emcore on the Closing Date (the
"Emcore  Warrant  Agreement").  The Emcore Warrant  Agreement  shall contain (A)
customary  representations  and warranties on the part of Emcore,  (B) customary
affirmative and negative  covenants  relating to Emcore and its business and (C)
the general terms set forth on Schedule 3.04 hereto.

accordance  with the  immediately  preceding  sentence,  shall be  liable to the
Company  for any such debt,  liability  or act.  Decisions  or actions  taken by
Members in accordance with this Agreement and the LLC Agreement (whether through
the Committee or otherwise) shall constitute decisions or actions by the Company
and  shall be  binding  on the  Company.  The  provisions  of the LLC  Agreement
regarding the decisions or actions to be taken by Members shall be substantially
the same as the corresponding provisions of this Agreement.

     Section  7.02  The  Committee.  (a)  The  LLC  Agreement  provides  for the
establishment of the Committee and its operation. The Committee shall consist of
five individuals, two appointed by each of GEL and Emcore and a fifth, who shall
be the Company's  President and who shall be selected in accordance with section
7.04(a) of this Agreement and treated for all purposes of this Agreement and the
LLC  Agreement as being  appointed  to the  Committee by GEL. If at any time the
Company does not have a President,  GEL may designate the fifth appointee to the
Committee,  who shall serve until a President is appointed  in  accordance  with
section 7.04(a) of this  Agreement.  The appointees to the Committee shall serve
at the  pleasure  and on behalf of the party  that  appointed  them,  until such
appointee  resigns or is  removed by the  appointing  party.  Appointees  to the
Committee  need not be  officers,  directors  or  employees  of a Member  or the
Company;  provided,  however,  that if a Member's  appointee  is not an officer,
director or employee of such Member, an Affiliate of such Member or the Company,
the appointment of such individual shall be subject to the approval of the other
Member, which approval shall not be unreasonably  withheld.  An appointee to the
Committee may be removed, with or without cause, only by the appointing party.

     (b) A majority  of the  authorized  number of  Committee  appointees  shall
constitute  a quorum for the  transaction  of business by the  Committee,  which
majority  shall,  subject to the remaining  provisions of this section  7.02(b),
include  at least  one  appointee  of GEL,  other  than the  President,  and one
appointee of Emcore.  If a quorum is not present at the time and place appointed
for any meeting of the  Committee,  a majority of those  present may adjourn the
meeting and reschedule a subsequent  meeting of the Committee,  which subsequent
meeting  shall be duly  noticed to all  Members and be no less than five (5) nor
more than thirty (30) days from the date of the original meeting and if a quorum
is not present at the time and place appointed for the subsequent meeting of the
Committee solely by reason of the absence of the  representatives  of the Member
that  were  not  present  at  the  adjourned  meeting,  then a  majority  of the
authorized  number of  Committee  appointees  (including  the  President)  shall
constitute  a quorum for the  transaction  of business by the  Committee at such
subsequent meeting.

     (c) The Members shall act through their  appointees to the Committee in the
manner set forth below.  The  Committee  shall have the authority to, and shall,
conduct the affairs of the Company on behalf of the Members  pursuant to, and in
accordance  with, the Strategic  Business Plan and the Annual  Operating  Plans.
Decisions by the Committee  will require the  affirmative  vote of a majority of
the total number of Members' appointees  constituting the Committee,  whether or
not all appointees are present and without giving effect to any vacancies on the
Committee.

     (d) Each Member shall designate its representatives on the Committee to the
other Member in writing,  and such designation  shall remain in effect until the
revocation of such  designation  has been made in writing.  Such writing will be
signed by the chief executive officer of Emcore in the case of Emcore and by the
chief executive officer of GEL.

provisions  of this Article 7 and subject to the proviso in the second  sentence
of   Section   3.01(b)(i)   hereof,   the   following   actions   (collectively,

     indebtedness described in paragraph (iv) above, (b) Liens for taxes not yet
     due  or  delinquent  or  being  contested  in  good  faith  by  appropriate

     law with respect to a liability that is not yet due or delinquent;

          (vi) the  acquisition  of  another  Person  or of assets  (other  than

     unaffiliated third parties;

          (xi) any amendment to any Ancillary  Agreement between the Company and

                                   ARTICLE 8
                MEMBERSHIP; DISPOSITIONS OF MEMBERSHIP INTERESTS

     Section 8.01  Members.  Emcore shall be admitted to the Company as a member
of the Company  effective as of the execution of the LLC Agreement.  Each Member
shall have their  respective  Membership  Interest set forth on Exhibit A to the
LLC  Agreement,  as the same may be  increased  or decreased as provided in this
Agreement. Except as set forth in this Agreement and the LLC Agreement, a Member
does not have the right or power to withdraw from the Company as a Member.

     Section 8.02  Disposition of a Membership  Interest.  (a)  Prohibition.  No
Membership  Interest,  or any right,  title or interest in or to such Membership
Interest,  now or  hereafter  owned,  held or  acquired  by any Member  shall be
Disposed of voluntarily,  involuntarily, directly or indirectly, by operation of
law, with or without  consideration,  or otherwise except in accordance with the
provisions of this section 8.02. Any Disposition  which does not comply with the
provisions  of this section  8.02 shall be void ab initio and the Company  shall
not give effect to such attempted Disposition in its records.

     (b)  Affiliates;  Sale of Business.  Any Member may Dispose of all (but not
less than all) of its right, title and interest in and to a Membership  Interest
as follows:

          (i) to an Affiliate of such Member;

REQUEST.  REDACTED  MATERIAL IS MARKED WITH A *** AND HAS BEEN FILED  SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION.

               (ii) by GE to the purchaser,  directly or indirectly,  of GEL (or
          substantially all of the assets of GEL); or

               (iii) by Emcore to the  purchaser,  directly  or  indirectly,  of
          Emcore (or substantially all of the assets of Emcore);

provided,  however, that any Disposition pursuant to items (ii) or (iii) of this
clause (b) shall be made in compliance with the  requirements of clauses (d) and
(e), below.

GEL and Emcore shall remain  responsible  for the  performance of this Agreement
and the LLC  Agreement  by each  Affiliate  of such party to which a  Membership
Interest is transferred  pursuant to this section  8.02(b).  If any Affiliate to
which a Membership Interest is transferred  pursuant to this section 8.02 ceases
to be an  Affiliate  of the  Member  from  which  it  acquired  such  Membership
Interest,  such Person shall promptly reconvey such Membership  Interest to such
transferring  Member  (unless  such  Person  ceases to be such an  Affiliate  in
connection with a transfer otherwise permitted by this section 8.02).

     (c) Duty of First Offer After Five Years.  Following the  expiration of the
five-year period commencing on the date hereof (the "Restricted Period"), either
Member  (the  "Disposing  Member")  may  determine  to  Dispose  of  its  entire
Membership  Interest  (the  "Negotiated  Interest")  to a Person  that is not an
Affiliate,  as  follows.  The  Disposing  Member  shall in good faith  negotiate
exclusively  with the other  Member  for a period  of 60 days (the  "Negotiation
Period")  with a view to  Disposing  of the  Negotiated  Interest  to the  other
Member.  If no  agreement  can be reached  by the end of the 60-day  period on a
purchase price  satisfactory to both Members,  then either Member shall have the
right to require that *** of the Negotiated Interest be determined,  which value
shall  become  the  purchase  price  for  that  Interest.  If  after  *** of the
Negotiated  Interest has been  determined the  non-Disposing  Member declines to
purchase the Negotiated Interest,  the Disposing Member shall be free to Dispose
of all, but not less than all, of the  Negotiated  Interest so long as the terms
on which the Disposing Member  determines to Dispose of the Negotiated  Interest
are not  materially  less  favorable  to the  Disposing  Member  than the  terms
rejected by the Disposing Member during the Negotiation Period;  provided,  that
if the Disposition of such Negotiated Interest has not been consummated prior to
the  end of the  180-day  period  following  the end of the  Negotiation  Period
(subject to any  extension  necessary to comply with any  applicable  regulatory
requirement),  such  Disposition may not occur and the disposing  Member and the
Negotiated Interest shall again be subject to this section 8.02(c).

     (d) Option to Purchase.  (i) If during the Restricted Period or thereafter,
(1)  Emcore  becomes  subject  to a  Disposition  (by  merger,  sale of stock or
substantially all of the assets thereof or otherwise), including its interest in
the Company, or (2) GE proposes to Dispose,  directly or indirectly,  of GEL (by
merger,  sale of stock or substantially all of the assets thereof or otherwise),
including its interest in the Company, (any such business, a "Subject Business")
then  the  Member  that  is  the  subject  of  a  proposed   Disposition,   (the
"Transferring Member") shall provide prompt

REQUEST.  REDACTED  MATERIAL IS MARKED WITH A *** AND HAS BEEN FILED  SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION.

written  notice  (the  "Transfer  Notice")  to the other  Member  (the  "Offeree
Member").  The  Transfer  Notice  shall  identify  the  Person  with  which such
transaction  is proposed to be  consummated  and all other material terms of the
proposed  transaction,   including,  if  and  to  the  extent  applicable,   the
consideration  to be paid for (or  specifically  allocable  to) such  Membership
Interest,  and, in the case of an offer in which the  consideration  payable for
the Offered Interest  consists in whole or in part of  consideration  other than
cash, such  information  relating to such other  consideration  as is reasonably
necessary for the other Member to be informed of all material  facts relating to
such consideration.

     (ii) The Offeree Member shall have the right and option, for a period of 60
days after the date the Transfer Notice and all other information required to be
provided to the  Offeree  Member has been  received  by the Offeree  Member (the
"Notice Period"),  to deliver a notice to the Transferring Member (the "Purchase
Notice") of the Offeree Member's  intention to purchase the Membership  Interest
of the Transferring  Member (the "Offered  Interest").  The purchase price to be
paid by the Offeree Member to the  Transferring  Member for the Offered Interest
shall be cash in an amount equal to *** of that  interest.  Notwithstanding  the
preceding  two  sentences,  if the  consideration  to be paid for  such  Offered
Interest is wholly or partially non-cash consideration,  then the Offeree Member
shall pay cash in lieu of the non-cash consideration,  in an amount equal to ***
thereof,  such amount to be  determined by good faith  negotiations  between the
parties  (and, in the absence of  agreement,  using a procedure  similar to that
used to determine *** of an Interest in the  Company).  Delivery of the Purchase
Notice by the Offeree  Member shall  constitute an  irrevocable  election by the
Offeree Member to purchase the Offered Interest for the consideration and on the
other terms and conditions set forth above.

     (iii) The transfer of the Offered  Interest to the Offeree  Member shall be
consummated as soon as practicable  following the giving of the Purchase  Notice
by the Offeree Member, but in no event more than 30 days thereafter  (subject to
any extension necessary to comply with any applicable  regulatory  requirement).
If at the end of the Notice  Period the  Offeree  Member  shall not have given a
Purchase Notice with respect to the Offered Interest, the Offeree Member will be
deemed to have waived its rights under this section  8.02(d) with respect to the
Disposition  contemplated by the Transfer Notice.  If the Offeree Member rejects
the Transfer Notice,  or is deemed to have waived its rights as set forth in the
preceding  sentence,  the Transferring Member shall have the right, for a period
of 180 days  following  such  rejection  or  waiver  (subject  to any  extension
necessary to comply with any applicable regulatory  requirement),  to dispose of
the Subject Business or all, but not less than all, of the Offered Interest,  as
the case may be, to the proposed  transferee  identified in the Transfer  Notice
and, if the  proposed  transaction  is a transfer of a Membership  Interest,  on
terms no more  favorable  to the proposed  transferee  than are set forth in the
Transfer Notice. If, at the end of the 180-day period following the rejection or
waiver  (subject  to any  extension  necessary  to  comply  with any  applicable
regulatory  requirement),  the Transferring Member has not completed the sale of
the Subject Business or Offered  Interest,  as the case may be, such Disposition
may not occur and the  Transferring  Member and the Offered Interest shall again
be subject to the restrictions contained in this section 8.02(d).

     (e) Status as a Member.  Upon  execution of a counterpart of this Agreement
and compliance with the other applicable  requirements of this section 8.02, the
transferee  shall be deemed a "Member"  for the  purposes of and a party to this
Agreement  , and shall have the rights  and be subject to the  obligations  of a
Member hereunder and a party hereto with respect to the Membership Interest held
by such transferee.

     (f) Costs.  The Member effecting a Disposition and any Person admitted as a
Substitute  Member in connection  therewith  shall pay, or reimburse the Company
for,  all  reasonable  costs  incurred  by the  Company in  connection  with the
Disposition  (including,   without  limitation,   any  legal  fees  incurred  in
connection with the  consideration of the implications  thereof under applicable
securities  laws,  the Code and other laws) on or before the tenth day after the
receipt by that Person of the Company's invoice for the amount due.

purchase  Emcore's  Membership  Interest at the price and on the terms set forth
below, and Emcore shall sell to GEL such interest, and (ii) if Emcore is the non
breaching  Party,  then Emcore shall have the right (the "Put Right") to require
GEL to purchase Emcore's  Membership  Interest at the price and on the terms set
forth below, and GEL shall purchase such interest.

     (b) The Call Right and the Put Right may only be exercised by the giving of
written  notice (the "Buy-out  Notice") by the non breaching  Party to the other
Party within  thirty (30) days after a final  determination  by a court that the
other  Party  is in  Material  Breach.  Delivery  of the  Buy-out  Notice  shall

purchase and sale of Emcore's  Membership  Interest shall be consummated as soon
as practicable  following the  determination of *** of that Interest,  but in no
event more than 30 days thereafter (subject to any extension necessary to comply
with any applicable regulatory requirement). *** of Emcore's Membership Interest
shall be determined as provided in the Definition of *** in this Agreement, with
the Company being treated as a going concern immediately prior to the occurrence
of the event that gave rise to the  Material  Breach  referred to in  subsection
10.04(a),  above. The purchase price for Emcore's  Membership  Interest shall be
paid in cash at the  closing  of the  transaction  and  shall  be  equal  to ***
thereof.

     (c) The Put Right and the Call Right in this section  10.04 are in addition
to any other remedy that may be available to Emcore and GE, respectively,  for a
Material  Breach,  and if the  provision the violation of which gave rise to the
Material  Breach is directly  related to the  licensing  or use of  Intellectual
Property,  the Parties agree that the non  breaching  Party shall be entitled to
injunctive relief or specific  performance of the terms thereof,  in addition to
any other remedy that may be available in equity.

     Section 10.05 Effect of Termination.  (a) At such time as any Member ceases
to be a Member (either through transfer of its Membership Interest or otherwise)
of the  Company,  such  Member  shall  have such  rights  and be subject to such
obligations  as are expressly  provided in the other terms of this Agreement and
shall  have  those  additional   rights  and  be  subject  to  those  additional
obligations as are expressly provided in the terms of the Ancillary  Agreements.
At such time as any Member ceases to be a Member (either through transfer of its
Membership Interest or otherwise) of the Company, such Member shall no longer be
bound by the terms of Section 9.03 hereof and, subject to its other  obligations
hereunder  and under the  Ancillary  Agreements,  shall be free to engage in any
business  (new or  existing)  or acquire an  interest in or invest in any Person
engaged  in  any  business,   including,   without  limitation,  a  business  in
competition with the Company.

     (b) The  provisions  of  sections  9.01,  9.02,  10.05  and  11.02  of this
Agreement shall survive the termination of this Agreement.


                                  ARTICLE 11
                   SURVIVAL OF REPRESENTATIONS AND WARRANTIES
                                       AND
                                 INDEMNIFICATION

     Section 11.01 Survival of Representations  and Warranties.  Notwithstanding
any investigation  made by either GE or Emcore or the Company or such party's or
the Company's  representatives with respect to the representations or warranties
of the other party, all  representations and warranties of the parties contained
in this  Agreement and the LLC Agreement  shall survive the Closing for a period
of three years from and after such Closing  after which time





no claim for  breach of a  representation  or  warranty  or  indemnification  in
respect thereof may be brought by any Member; provided, that the representations
and  warranties  contained  in item  (g)(ii) of the Emcore  representations  and
warranties  on  Exhibit  D to  this  Agreement  and in  item  (g)(ii)  of the GE
representations and warranties on Exhibit D to this Agreement shall survive such
Closing indefinitely.

     Section 11.02 Indemnifiable Claims. Subject to any limitations set forth in
any Transaction  Document (including section 11.01 above), GE and Emcore, as the
case may be,  hereby  agree to  indemnify  each other and the  Company  (without
duplication)  and their  respective  Affiliates,  and,  to the  extent  actually
indemnified  by GE,  Emcore,  the Company or such  Affiliate  from time to time,
their respective directors, officers, employees and agents against, and agree to
hold them harmless from, any and all Damages incurred or suffered by any of them
arising out of or related in any way to (i) any  misrepresentation  or breach of
any representation or warranty made by GE or Emcore in this Agreement or the LLC
Agreement or (ii) the breach or  non-performance  of any covenant or  obligation
required by this  Agreement or the LLC  Agreement to be performed or observed by
GE or Emcore; provided, however, that neither GE nor Emcore shall be required to
pay the first $250,000 in aggregate  amount of any Damages  arising under clause
(i) of this section 11.02.

     Section 11.03 Procedures.  (a) Notice.  Each party to this Agreement agrees
to give prompt notice to the other parties to this Agreement of the assertion of
any claim, or the  commencement of any suit,  action or proceeding  brought by a
Person that is not a party to this Agreement  ("Indemnified  Claims") in respect
of which GE,  Emcore,  the  Company  or their  respective  Affiliates,  or their
respective directors, officers, employees or agents seek indemnity under section
11.02,  after  such  party  becomes  aware  of the  facts  giving  rise  to such
Indemnified  Claim.  The failure of any party to provide notice pursuant to this
section  11.03(a)  shall  not  constitute  a waiver  of that  party's  claims to
indemnification  pursuant to section 11.02 in the absence of material  prejudice
to the party that did not receive such notice.  Any such notice to a party shall
be accompanied by a copy of any papers theretofore served on the notifying party
in connection with the Indemnified Claims.

     (b) Defense and  Settlement  of Claims.  (i)  Assumption  of Defense.  Upon
receipt of notice from a party  seeking  and  entitled  to  indemnification  (an
"Indemnified  Party")  pursuant to this Agreement,  the party or parties against
whom  indemnification  is sought (an "Indemnifying  Party") will, subject to the
provisions  of section  11.03(b)(ii),  assume the  defense  and  control of such
Indemnified  Claims  but  shall  allow  the  Indemnified  Party  or  Parties,  a
reasonable  opportunity to participate in the defense  thereof with its or their
own counsel and at its or their own expense.  The  Indemnifying  Party shall (A)
select  counsel,   contractors  and  consultants  of  recognized   standing  and
competence after  consultation with the Indemnified  Party or Parties,  (B) take
all steps  necessary in the defense or  settlement  thereof and (C) at all times
diligently and promptly pursue the resolution thereof.  The Indemnified Party or
Parties  shall,  and shall cause each of their  respective  Affiliates and their
respective directors,  members,  officers,  employees,  and agents to, cooperate
fully with the Indemnifying Party in the defense of any Indemnified Claim.

     (ii) Settlement of Claims.  The  Indemnifying  Party shall be authorized to
consent to a  settlement  of, or the entry of any  judgment  arising  from,  any
Indemnified Claims, without the consent of any Indemnified Party; provided, that
the Indemnifying Party shall (A) pay or cause to be paid all amounts arising out
of such settlement or judgment concurrently with the effectiveness  thereof, (B)
not  encumber  any of the  assets  of any  Indemnified  Party  or  agree  to any
restriction  or condition that would apply to such  Indemnified  Party or to the
conduct of that party's  business,  (C) obtain, as a condition of any settlement
or other solution,  a complete release of each Indemnified Party and (D) provide
to the  Indemnified  Party  notice  of the  proposed  settlement  prior  to such
settlement.

All necessary  and  appropriate  corporate  action has been taken by Emcore with

law, rule,  regulation,  writ,  decree or order to which Emcore is subject,  nor
will it  conflict  with or  result in a default  under  any term,  provision  or
covenant of any mortgage,  indenture,  contract,  agreement (including,  without
limitation,  the Amended and Restated Joint Venture  Agreement  between Uniroyal
Technology  Corporation  and Emcore dated November 30, 1998 (the "Uniroyal Joint

obtained by Emcore  under any  material  agreement to which Emcore is a party in
connection with the execution, delivery or performance of the Emcore Transaction
Documents.  Emcore  is not a party  to or  bound  under  any  (and  to the  best
knowledge of Emcore there is no pending,  proposed or  threatened),  regulation,
certificate, mortgage, lien, lease, agreement, contract, instrument, law, order,
judgment or decree, or any similar  restriction not of general application which
reasonably  could be  expected  to  adversely  effect  the  consummation  of the

Documents  require no action by or in respect of, or consent or approval  of, or

inquiry,  administrative  or judicial,  pending or, to the  knowledge of Emcore,
threatened  against Emcore,  at law or in equity,  before any federal,  state or
local court or regulatory  agency,  or other  governmental  authority,  which if
adversely determined would have an adverse effect on Emcore's ability to perform

Documents.
