       2.7 below,  {redact}  neither Party shall be prohibited  from  designing,
       developing,  marketing or selling product components (including,  without
       limitation,  components used in Products) to third parties; provided that
       such  Party is not paid or  compensated  other  than for the sale of said
       components  and for the design and  development of said  components.  The
       Parties  acknowledge that either Party may acquire third parties (each an
       "Acquired Company") that have expertise,  intellectual  property,  and/or
       carry on business relating to the Products (collectively the "Business").
       {redact}

2.5    Notwithstanding  Section  2.4  above,  EMCORE  shall  have  the  right to
       terminate  its  {redact}  obligations  under said  Section  2.4 as to any
       Product  subject to this Agreement  (but not this  Agreement  itself) for
       which JDSU fails to sell the Minimum  Volume of such  Product as provided
       in this  Section 2.5 during any six month  period (the first such six (6)
       month  period for each  Product to  commence  three (3) months  after the
       Commercial  Launch Date for that  Product);  provided that  purchases for
       resale  pursuant to Section 8.2 shall be counted as sales.  JDSU shall be
       credited for sales towards the Minimum Volume in any six (6) month period
       for the sum of that number of Product units purchased by JDSU for resale,
       sold by JDSU and that number of Product  units  ordered  for  shipment by
       JDSU during that six (6) month period in accordance  with this  Agreement
       that EMCORE failed to timely ship during that six (6) month period.  JDSU
       shall be  required  either to  purchase  for resale or sell such  Minimum
       Volume  amounts to  maintain  EMCORE's  {redact}  obligations  under said
       Section 2.4, but shall not be deemed in breach of any of its  obligations
       hereunder  solely for failure to purchase for resale or sell such Minimum
       Volume amounts.

2.6    Notwithstanding  Section  2.4  hereof,  JDSU  shall  have  the  right  to
       terminate its non-compete obligations pursuant to Section 2.4 above as to
       any Product subject to this Agreement (but not this Agreement  itself) as
       follows:

       (a)    Should  EMCORE  fail to ship that  quantity  of units of a Product
              subject to the Customer  Commitment in accordance with Section 6.2
              hereof  that  constitute   {redact}  percent  ({redact}%)  of  the
              aggregate units of such Product subject to the Customer Commitment
              (other than a failure to ship  caused by JDSU's  failure to supply
              or delay in supplying  parts used in the  Product)  during any six
              (6) month period (such six (6) month period to commence  three (3)
              months after the Commercial  Launch Date for that Product)  during
              the term of this Agreement, JDSU shall have the right to terminate
              the {redact}  provisions as to such Product on not less than sixty
              (60) days  notice to  EMCORE,  which  shall have the right to cure
              such delinquency during that sixty (60) day period by the shipment
              of all units in arrears and the timely  shipment of all additional
              units of such Product subject to the Customer Commitment that have
              shipment dates within that thirty (30) day period; or

       (b)    Should EMCORE ship units of a Product to a third party customer or
              JDSU that have warranty return rates in excess of {redact} percent
              ({redact}%) (other than as a result parts supplied by JDSU) during
              any six (6) month  period  (such six (6) month  period to commence
              three  (3)  months  after  the  Commercial  Launch  Date  for that
              Product),  JDSU shall  have the right to  terminate  the  {redact}
              provisions  as to such  Product  on not less than  sixty (60) days
              notice to EMCORE, which shall have the right to cure such warranty
              failure  problem  by:  (i)  creating  a  corrective   action  plan
              regarding such warranty failure problem,  which plan is reasonably
              acceptable to JDSU, and (ii) shipping  replacement Products to the
              third party  customer or JDSU,  as  applicable,  during that sixty
              (60) day  period  that have a warranty  failure  rate of less than
              {redact}  percent  ({redact} %);  provided,  however,  that EMCORE
              shall not be deemed in breach of any of its obligations  hereunder
              solely for failure to meet its obligations under (a) or (b) above.

2.7    In the event that either  EMCORE or JDSU shall  exercise its rights under
       Section 2.5 or 2.6 above to  terminate  its  {redact}  obligations  under
       Section 2.4 above as to a Product,  the {redact} obligations of the other
       Party shall also be terminated  as to such Product.  At any time that the
       Parties are not subject to the {redact}  obligations set forth in Section
       2.4 above with  respect to a  particular  Product,  commissions  shall be
       payable to JDSU only with  respect to units of that  Product sold through
       JDSU in accordance  with this Agreement.  {redact},  this Agreement shall
       not serve to restrict either Party as to the development,  manufacture or
       sale of any other  products that they may elect to pursue during the term
       of this Agreement.

3.     Collaboration and Initial Work of the Parties

3.1    The  Parties  shall  collaborate  in good faith under the  Agreement  and
       shall,  subject to the  confidentiality  restrictions  imposed hereunder,
       provide to the other Party such  Company  Information  as the  disclosing
       Party determines in good faith is reasonably required for the performance
       of its obligations under the Agreement.

3.2    EMCORE shall as soon as practicable after the Effective Date commence its
       development work pursuant to the Initial  Statement of Work. The Steering
       Committee  shall within sixty (60) days after the Effective  Date jointly
       prepare  a  Statement  of Work  for the  first of the  Identified  Future
       Products and on a thirty (30) day schedule for each additional  Statement
       of Work  thereafter,  complete  preparation of Statements of Work for the
       remaining three Identified Future Products within one hundred fifty (150)
       days after the Effective  Date.  Each of the Identified  Future  Products
       shall become subject to this Agreement upon the agreement by the Steering
       Committee as to such  Statements of Work and the other items set forth in
       Section  5.3(a) hereof,  and the failure of the Steering  Committee to so
       agree as to any Identified Future Product shall cause such product to not
       become  subject to this  Agreement.  As to the  Initial  Product  and any
       Identified Future Product that the Steering Committee agrees shall become
       a Product for the  purposes of this  Agreement  pursuant to said  Section
       5.3(a),  each Party agrees to use its reasonable best efforts to complete
       its work  within  the  development  schedules  set  forth in the  Initial
       Statement  of Work and the  Statements  of Work for each such  Identified
       Future Product made subject to this Agreement. Within ninety (90) days of
       the date  hereof,  the  Parties  shall  prepare a  product  road map (the
       "Product  Road Map")  containing a five (5) year  forecast of  fiberoptic
       array  transceivers  contemplated for design and development as potential
       Future Products to enable the Parties to extend their relationship beyond
       the  development  and  commercialization  of the Initial  Product and the
       Identified Future Products.  Such Product Road Map shall not be deemed to
       bind either Party as to any Future Product until such time as the Parties
       shall have agreed to make such Future  Product  subject to this Agreement
       pursuant  to Section  5.3(b).  3.3 During any period in which the Parties
       shall be developing a Product  pursuant to a Statement of Work undertaken
       pursuant to this  Agreement,  each Party shall  prepare and submit to the
       Steering  Committee its Work Report on a quarterly basis or on some other
       timely basis as decided by the Steering  Committee setting forth the work
       performed by each Party in the previous  quarter in  furtherance  of such
       Statement of Work.

3.4    JDSU shall prepare (with input from EMCORE) a world-wide  marketing  plan
       for each of the Products  (the  "Marketing  Plan") on a quarterly  basis,
       which will be reviewed and approved by the Steering Committee.

3.5    In the event that a Party's  development  work under a Statement  of Work
       for a Product is  unsuccessful,  the  Parties  shall  either  modify such
       Statement  of Work (or  Specifications)  for  that  Product  through  the
       Steering  Committee,  or, in the absence of an  agreement by the Steering
       Committee as to such modification,  terminate development of such Product
       and cause such  Product to cease to be  subject  to this  Agreement.  For
       purposes of the foregoing  sentence,  development  work of a Party may be
       deemed unsuccessful, as determined by the Steering Committee, if: (i) the
       period to  complete  such  development  is delayed by  {redact} % or more
       based on the schedule  for  development  set forth in the then  effective
       Statement of Work; or (ii) the  development is not  reasonably  likely to
       result in a Product that meets the then effective  Specifications  in all
       material respects.

4.     Management of the Program

4.1    The Parties shall as soon as practicable after the Effective Date, but in
       any event within thirty (30) days,  establish  the Steering  Committee to
       supervise the performance of the Parties pursuant to this Agreement.  The
       Steering  Committee  shall have an equal  number of members  appointed by
       each  Party  and  shall  be  initially  comprised  of a total of four (4)
       members,  and  the  members  of each  Party,  including  any  replacement
       members,  shall be  subject to the  approval  of the other  Party,  which
       approval shall not be unreasonably withheld. The total number of Steering
       Committee  members may be changed by the Steering  Committee from time to
       time as appropriate provided that in all cases it will be comprised of an
       equal number of members from each Party.  Each Party may  substitute  its
       representatives from time to time (subject to approval of the other Party
       as provided  above) and the  substitution is effective upon notice to the
       other Party.

4.2    The  Steering  Committee  shall meet as often as  required  to ensure the
       effective operation of this Agreement but in no event less than quarterly
       on such date and at such place as to be agreed upon  between the Parties;
       provided  that  members of the  Steering  Committee  will be permitted to
       attend such meetings by electronic or telephonic  means.  The meetings of
       the Steering  Committee may be held in person or in any other  reasonable
       manner, including,  without limitation, by telephone, video conference or
       e-mail.  Each of the Steering  Committee  members shall have one vote and
       other than decisions  requiring  unanimous approval all decisions must be
       made  by  a  majority   vote.   It  is   contemplated   that   additional
       representatives of the Parties may attend and participate in the Steering
       Committee meetings,  however, such additional representatives will not be
       entitled to participate in the voting process.

4.3    As  a  first  order  of  business,  the  Steering  Committee  will  draft
       procedures which will govern the operation of the Steering  Committee and
       its decision  making process and the specific  criteria to be used in the
       determinations set forth in Section 4.4.

4.4    The Steering Committee or its designees shall be responsible for:

       4.4.1  reviewing, approving and, as necessary,  modifying,  Statements of
              Work and  Specifications  for each of the Initial  Product and any
              Identified  Future Products or Future Product made subject to this
              Agreement pursuant to Section 5.3 hereof;

       4.4.2  reviewing and, if necessary,  adjusting the Estimated  Development
              Costs for each Product;  4.4.3  reviewing  and approving  EMCORE's
              manufacturing capabilities for each Product to ensure a consistent
              supply and  appropriate  quality  assurance  and  quality  control
              ("QA/QC") compliance as to that Product;

       4.4.4  determining   the  Minimum  Volumes  for  each  Product  for  each
              successive six (6) month period  following the  Commercial  Launch
              Date of such Product  (provided  that the first such six (6) month
              period for each Product shall  commence three (3) months after the
              Commercial  Launch  Date for  purposes  of  Section  2.5  hereof),
              reviewing  and approving  the  Marketing  Plan,  and reviewing the
              progress of JDSU in fulfilling the objectives set forth therein on
              a quarterly basis;

       4.4.5  reviewing the quarterly Work Reports submitted by each Party;

       4.4.6  approving  the  Product  Trademarks  selected  by the  Parties  in
              accordance with Section 4.5;

       4.4.7  establishing   and,  on  a  quarterly   basis,   reviewing  JDSU's
              commissions  and  pricing  between  the  Parties  for the  Initial
              Product and any Future  Products  as provided in Sections  8.1 and
              8.2;

       4.4.8  establishing a Product  Release  Checklist for the Initial Product
              and any Future Products;

       4.4.9  reviewing  and approving  the  applicable  royalty rate each Party
              shall  be  obligated  to  pay  for  use  of  the  other   Parties'
              Intellectual Property as provided in Section 9.5 hereof;

       4.4.10 reviewing  the  Parties'  accounting  methodologies  and  Internal
              Accounts;

       4.4.11 reviewing and approving the development budget for Shared Research
              and  Development  Expenditures  (as  defined in  Section  5.4) and
              determining amounts, if any, owed from one Party to the other;

       4.4.12 establishing a warranty policy for each Product; and

       4.4.13 reviewing and approving the Product Road Map.

       If the Steering Committee cannot agree pursuant to Section 4.4.2 above as
       to an adjustment to a Party's  Estimated  Development  Cost for a Product
       and such Party determines in good faith that its actual  development cost
       will exceed its then effective Estimated Development Cost by {redact}% or
       more,  such Party shall have the option,  exercisable on thirty (30) days
       written  notice to the other  Party,  to  terminate  development  of such
       Product and cause such Product to no longer be subject to this Agreement.

4.5    Within a reasonable time so as to permit an expeditious commercial launch
       of the Initial  Product and those  Identified  Future  Products  that the
       Steering Committee determines to make subject to this pursuant to Section
       5.3(a),  the Parties shall select the trademarks to be used in connection
       with the Products  (the  "Product  Trademarks").  The Product  Trademarks
       shall  be  approved  by a  unanimous  vote  of  the  Steering  Committee.
       Application to register the Product  Trademarks so selected shall be made
       by JDSU at its own expense  and once  registered  the  Product  Trademark
       shall be  maintained by JDSU at its own expense and shall be owned solely
       by JDSU during and after the term of this Agreement;  provided,  however,
       that EMCORE shall be granted a fully  paid-up,  royalty free,  perpetual,
       exclusive (except as to JDSU) license to commercialize Products under the
       Product  Trademarks (which for purposes of such license shall not include
       the name JDS Uniphase or any  tradenames  or  trademarks  that include or
       otherwise use of the JDS Uniphase name or general  logo(s)) which license
       shall  terminate  earlier in the event of an uncured  material  breach of
       this Agreement by EMCORE. To the extent  practicable,  during the term of
       the  Agreement,  Product  labels and  packaging  shall  bear the  Product
       Trademarks and the trademarks and logos of each of the Parties.

4.6    Each Party shall  appoint a suitably  qualified and  experienced  Program
       Manager to manage the Program,  who shall be  responsible  for the day to
       day  operations  and  obligations  under the  Agreement of the Party that
       appointed him. The Program Managers shall be jointly  responsible for the
       preparation  of the Statement of Work and the Work Reports  required on a
       quarterly  basis.  The Program  Managers  shall also be  responsible  for
       regular and  periodic  updates of the Product Road Map to enable it to be
       used as a rolling five (5) year forecast of Future Product development.

4.7    The initial Program Managers shall be:

                  for EMCORE  -  {redact}
                  for JDSU    -  {redact}

4.8    In the event that the Steering  Committee is unable to make a decision on
       any particular  matter due to a deadlock,  it shall submit the matter for
       joint resolution to the Chief Executive Officers of the Parties (or their
       senior  officer  designees).  In the event that the  matter so  submitted
       remains  unresolved  after  30  days  either  Party  may  submit  it  for
       resolution in accordance with Section 21.  Notwithstanding the foregoing,
       the failure of the Steering Committee to agree as to any of the following
       items shall not give rise to the dispute  resolution  provisions  of this
       Section 4.8 or Section 21 below:

       (i)    a determination pursuant to Section 5.3 hereof to make any product
              (including,  without  limitation,  any Identified  Future Product)
              subject to this  Agreement,  in which case such product  shall not
              become subject to this Agreement;

       (ii)   the  Statement of Work,  Specifications  or Estimated  Development
              Cost  for any  Product  or  product  that is  proposed  to be made
              subject to this  Agreement,  in which case such product  shall not
              become subject to this Agreement;

       (iii)  any proposed  adjustment to a Party's Estimated  Development Cost,
              in which case such Party shall have the option provided in Section
              4.4 hereof; and

       (iv)   JDSU's commission, the price for a Product (other than the Initial
              Product) or Minimum  Volumes for a Product,  in which case Section
              2.4 shall cease to apply as to such  Product and  Sections  8.1 or
              8.2, as applicable, shall apply.

5.     Future Products; Product Research and Development

5.1    Consistent  with each Statement of Work,  EMCORE shall use its reasonable
       best efforts to provide, or shall procure from a third party,  sufficient
       engineering  support  and  assistance  to design and  develop the Initial
       Product (and any Future  Products as approved by the  Steering  Committee
       from time to time) to a stage where the Products meet the Specifications.
       It is agreed that for purposes of this Section 5.1 and Section 5.2 below,
       neither Party shall be deemed to provide any guarantee or assurance  that
       their  development work as to any Product will be successful in achieving
       the  Specifications or any targeted  manufacturing  cost for the Product,
       and each Party's obligations as to such development work shall be limited
       to its  reasonable  best efforts  through  expenditure  of its  Estimated
       Development  Cost for such Product to complete such  development  work as
       provided in the applicable Statement of Work.

5.2    Consistent  with each  Statement of Work,  JDSU shall use its  reasonable
       best efforts to provide  sufficient  mechanical  and optical  engineering
       support and  assistance,  including  optical  alignment of the arrays and
       mechanical  designs of interfaces,  to support  production of the Initial
       Product (and any Future  Products as approved by the  Steering  Committee
       from time to time) in finished and packaged form in  accordance  with the
       Specifications.

5.3    (a) The Parties  acknowledge that, in marketing the Initial Product,  the
       Parties have  determined  that  potential  customers  have an interest in
       assuring  that the  Parties  intend  to  develop  the  Identified  Future
       Products.  The  Steering  Committee,  shall within the times set forth in
       Section 3.2 hereof, meet to jointly determine in good faith the following
       with  respect  to  each  of the  four  Identified  Future  Products:  (i)
       Specifications,  (ii) a Statement  of Work,  (iii) the initial  Estimated
       Development  Cost and (iv) JDSU's  commission and the initial pricing for
       such  Product as  determined  in  accordance  with  Sections  8.1 and 8.2
       hereof.  Once the Steering  Committee has agreed as to clauses  (i)-(iii)
       with respect to any given one of the four Identified Future Products, the
       Parties shall, subject to the other terms of this Agreement, be obligated
       to develop,  manufacture and market such Product.  Neither Party, through
       its  representatives  on the Steering  Committee or  otherwise,  shall be
       deemed  to have  any  obligation  to make an  Identified  Future  Product
       subject to this Agreement if such Party determines in good faith that the
       pricing over the  estimated  life of such Product  cannot  reasonably  be
       expected to provide such Party with at least a {redact} % Gross Margin as
       provided in Section 8.2 hereof or, in JDSU's case,  it determines in good
       faith that it will not  receive a  reasonable  commission  as provided in
       Section 8.1  hereof.  In the absence of such  agreement  by the  Steering
       Committee as to any of the Identified  Future  Products,  such Identified
       Future  Products  shall  not be  deemed a Product  for  purposes  of this
       Agreement.

       (b) During  the term of this  Agreement,  the  Parties  shall,  by mutual
       written agreement through the Steering Committee,  determine those Future
       Products  (other  than the  Identified  Future  Products)  that  shall be
       subject to this  Agreement.  A Future  Product (other than the Identified
       Future  Products)  shall only be made subject to this  Agreement upon the
       written agreement of the Steering  Committee as to each of the following:
       (i)  Specifications,  (ii) a  Statement  of Work,  and (iii) the  initial
       Estimated  Development  Cost and (iv) JDSU's  commission  and the initial
       pricing for such Future Product as determined in accordance with Sections
       8.1 and 8.2 hereof.  The Parties  acknowledge that, upon agreement by the
       Steering  Committee  as to the  Specifications,  Statement  of  Work  and
       Estimated  Development  Cost for a  Future  Product  (including,  without
       limitation,  any of the Identified Future  Products),  a determination of
       Minimum  Volumes,  commission and initial pricing for such Future Product
       may not be then  practicable  and shall not be the then required to cause
       such  Future  Product  to  become  subject  to this  Agreement.  Prior to
       Commercial Launch Date for a Future Product, the Steering Committee shall
       determine in good faith the Minimum  Volumes for such Future  Product (as
       provided in Section  4.4.4  hereof),  JDSU's  commission  and the initial
       pricing for such  Future  Product  (as  provided in Sections  8.1 and 8.2
       hereof).  In the event that the  Steering  Committee  cannot  agree as to
       Minimum Volumes, JDSU's commission or initial pricing, such Product shall
       remain  subject to this  Agreement  as provided  in Sections  8.1 and 8.2
       hereof but not be subject to Section 2.4 hereof.

5.4    Each Party shall share bear its own share of the research and development
       costs  and  expenses  incurred  by  it in  connection  with  the  design,
       development and  manufacture of the Products.  The Parties shall {redact}
       share, {redact}, those costs that are approved in writing by the Steering
       Committee and that relate to certain capital expenditures including,  but
       not limited to, non-recurring engineering expenses,  application specific
       integrated  circuits  and  capital  equipment  (collectively  the "Shared
       Research  and  Development   Expenditures").   The  Parties'   respective
       contributions  in  connection  with the Shared  Research and  Development
       Expenditures  shall be taken into account by the Steering  Committee when
       setting JDSU's commission.

5.5    (a) {redact} Other than the Shared Research and Development Expenditures,
       each Party shall bear its own  expenses in  connection  with the research
       and  development  relating to the Initial  Product.  To permit  EMCORE to
       recover the Development  Cost  Difference,  if any,  relating to a Future
       Product  (other than an EMCORE  Developed  Product)  made subject to this
       Agreement pursuant to Section 5.3 hereof, JDSU agrees to accept a reduced
       commission  until such time as EMCORE has recovered the Development  Cost
       Difference  plus  {redact}% from three (3) months prior to the Commercial
       Launch Date of such Product.

       (b) In the event  that JDSU  orders a Product  from  EMCORE for resale to
       customers in accordance with Section 8.2, to permit EMCORE to recover the
       Development  Cost  Difference  for such  Product  (other  than an  EMCORE
       Developed Product), if any, plus {redact}% from three (3) months prior to
       the Commercial Launch Date, JDSU will remit to EMCORE  quarterly,  within
       thirty (30) days following the end of the quarter,  percent  ({redact} %)
       of the gross revenue  (defined to exclude VAT and other  applicable sales
       tax) received by JDSU or its Affiliates in the preceding  quarter through
       sale of (i) any  one of the  {redact}  Identified  Future  Products  made
       subject to this  Agreement  pursuant  to Section  5.3(a) and (ii)  Future
       Products made subject to this  Agreement  pursuant to Section 5.3(b) (the
       "R&D Off-Set").  For purposes of this Section 5.5, the actual development
       cost  of a Party  for a  Product  for  the  purpose  of  calculating  the
       Development  Cost  Difference  for such  Product  shall  not be deemed to
       exceed {redact} % of the Estimated Development Cost of that Party, as the
       same may be  adjusted  from time to time by the  Steering  Committee.  To
       assist EMCORE in the development of Future Products, JDSU may advance the
       estimated  Development Cost Difference at any time during the performance
       by EMCORE  of its  Statement  of Work as to such  Future  Product  as the
       Parties may agree in writing.

5.6    Each Party  shall  ensure  that all the work  conducted  by it under this
       Agreement  shall be carried out in  accordance  with  generally  accepted
       standards of good practice at the time applicable to such work (including
       but  without  limiting  the  generality  of the  foregoing  all  relevant
       statutory  safety  standards  from time to time in force)  and each Party
       will be responsible  for the  implementation  of and compliance  with all
       applicable safety and other legislative requirements.

5.7    Each Party will procure that such facilities,  materials and equipment as
       are reasonably required for the proper execution of the Statement of Work
       are made  available  by it.  Should  JDSU elect to  contribute  alignment
       equipment to EMCORE for  development  and  manufacturing  of the Product,
       JDSU will continue to own the equipment, and, for so long as EMCORE is in
       possession of the equipment, EMCORE shall be responsible for maintaining,
       repairing and insuring the equipment.

6.     Forecasts and Orders and Shipping Procedures for Products

6.1    Each potential purchase order from a customer for which JDSU will receive
       a commission shall be subject to EMCORE's prior approval regarding price,
       cancellation  penalties and shipping terms.  All purchase orders accepted
       by JDSU and EMCORE shall specify:

       (a)    Products  (including  EMCORE and JDSU part  numbers,  and  Product
              specification reference) and quantities being ordered;

       (b)    the applicable unit price for the Products;

       (c)    shipping instructions, including requested shipment dates;

       (d)    cancellation penalties; and

       (e)    distribution point of the Products and the invoicing location.

       Terms and  conditions  on customer  purchase  orders and  EMCORE's  sales
       acknowledgments,  other than those  agreed to between  the  customer  and
       EMCORE,  shall be of no  effect.  Within  ten (10)  business  days  after
       EMCORE's  receipt  of a  purchase  order,  EMCORE  will  issue a  written
       acknowledgment,  which will recite this Agreement reference, Product type
       number,  shipping  instructions,  the Product  quantities being sold, the
       Product's  applicable unit price and the estimated shipment dates. In the
       event of a conflict  between this  Agreement  and EMCORE's  written sales
       acknowledgment or a purchase order, this Agreement shall prevail.

6.2    Six (6) months prior to the  Commercial  Launch Date, as estimated by the
       Steering  Committee,  of the  Initial  Product  and  every  three  months
       thereafter  for so long as this  Agreement  shall  remain in force,  JDSU
       shall provide EMCORE with a rolling  {redact} month forecast (such period
       commencing upon such  Commercial  Launch Date) of its projected sales for
       the Products  that are subject to Section 2.4 of this  Agreement  (each a
       "Forecast"),  which Forecast will be prepared so as to be consistent with
       the Marketing  Plan to the extent  reasonably  practicable.  The Forecast
       shall  specify  the number and type of  Products  which JDSU  anticipates
       selling and the expected  delivery dates.  JDSU agrees to include as part
       of the Forecast {redact}. The quantities specified in the Forecast (i) in
       respect of the first {redact}  month period  ("Agreed  Shipment  Period")
       shall constitute a guaranteed  purchase forecast (a "Guaranteed  Purchase
       Forecast")  as to the type  and  quantity  of  Products,  delivery  dates
       specified  therein,  and (ii) in respect of the remaining  portion of the
       {redact} period covered thereby,  shall constitute a non-binding estimate
       of projected  sales and delivery  dates.  The  remaining  portion of each
       Forecast for periods beyond the Agreed Shipment Period shall be deemed an
       advisory forecast,  which shall not be binding on either Party; provided,
       however, that (i) the Guaranteed Purchase Forecast for an Agreed Shipment
       Period  shall not be more than  {redact}  percent  ({redact} %) higher or
       lower than the  immediately  preceding  Forecast for that period  without
       EMCORE's prior written consent and (ii) the Forecast for any given Agreed
       Shipment  Period  shall not be more than  {redact}  percent  {redact}( %)
       higher  or lower  than the  initial  Forecast  for  such  period  without
       EMCORE's prior written  consent.  Each Forecast shall be accompanied by a
       purchase order for the Product units subject to the Customer Commitment.

6.3    If JDSU reduces or cancels any portion of a Guaranteed  Purchase Forecast
       during the Agreed  Shipment  Period,  JDSU shall be  responsible  for the
       Cancellation   Costs   incurred  as  a  result  of  such   reduction   or
       cancellation;  provided,  however,  that JDSU's liability with respect to
       such costs shall be: {redact}  percent  ({redact} %) of the  Cancellation
       Costs if EMCORE receives written  notification of cancellation  from JDSU
       {redact} in advance;  {redact}  percent  ({redact} %) of the Cancellation
       Costs if EMCORE receives written  notification of cancellation  from JDSU
       {redact} in advance;  {redact}  percent  ({redact}%) of the  Cancellation
       Costs if EMCORE receives written  notification of cancellation  from JDSU
       {redact} in advance;  and {redact} percent {redact} % of the Cancellation
       Costs if EMCORE receives written  notification of cancellation  from JDSU
       {redact} days in advance. Notwithstanding the foregoing, JDSU will not be
       liable for Cancellation Costs relating to sales cancellations by JDSU (in
       respect of sales directly to JDSU) or by a customer due to Products being
       the subject of warranty  returns as specified in Section 10 hereof (other
       than returns  resulting  from the failure of {redact},  and JDSU shall be
       entitled  to return  any such  Products,  which  did not meet  applicable
       Specifications  when shipped by EMCORE (other than returns resulting from
       the failure of  {redact}),  for a full refund of amounts  paid to EMCORE,
       after any applicable commissions to JDSU, for such Products.

6.4    Should JDSU at any time during the term of this Agreement  refer an order
       for  Products  in  excess  of  the  amount  of  the  applicable  Customer
       Commitment  and  which  would  also  exceed  EMCORE's  (or  its  contract
       manufacturer's)  available  manufacturing capacity for a given Product as
       of the date of the  Forecast,  the Parties  agree to cooperate  with each
       other  and to use all  reasonable  efforts  to fill the  Product  demand,
       including without limitation,  sharing the expenses of expanding EMCORE's
       manufacturing capacity on such terms as the Parties may agree in writing.
       The Parties'  respective  contributions in connection with such expansion
       of EMCORE's  manufacturing  capacity  shall be taken into  account by the
       Steering Committee when setting JDSU's commission.

6.5    Within  {redact}  days of  execution of this  Agreement,  JDSU will order
       evaluation  quantities  of  the  Initial  Product  in  accordance  with a
       purchase  order  issued  by  JDSU  in  compliance   with  this  Agreement
       ("Development  Purchase Order").  The price per module in the Development
       Purchase  Order  shall  be  determined  by the  Steering  Committee.  The
       evaluation  quantities  of the  first  of the  Initial  Product  shall be
       delivered  in  accordance  with the dates  set  forth in the  Development
       Purchase  Order and in any event,  not  earlier  than  completion  of the
       Program.

6.6    On commission sales, pursuant to Section 8.1, EMCORE shall be responsible
       for processing and invoicing all purchase orders received from customers.
       EMCORE  will  invoice  JDSU for the  Development  Purchase  Order and the
       Initial Purchase Order upon shipment. All payments owed by JDSU to EMCORE
       under  this  Agreement,   including,  without  limitation,   cancellation
       charges,  agreed price adjustments,  and payment for Products  purchased,
       are payable in U.S.  dollars and will be due net {redact}  days after the
       date of the invoice.

6.7    Delivery  of  the  Products  shall  be  {redact}  EMCORE's  manufacturing
       facility as per  International  Chamber of Commerce (ICC)  Incoterms 2000
       edition.

6.8    EMCORE  shall be permitted  to make  engineering  changes to the Products
       during the term of this Agreement that affect such Product's  performance
       or  reliability,  or  form,  fit and  function;  provided,  that any such
       engineering change provides a cost, performance or other material benefit
       or is  reasonably  required to minimize  environmental,  health or safety
       risks or is mandated by law. EMCORE shall give JDSU notice  regarding any
       such engineering changes to the Product, and the Parties shall thereafter
       use  reasonable  efforts to develop,  within  four (4) weeks,  a mutually
       acceptable  qualification  plan for Product  containing such  engineering
       changes. JDSU shall not unreasonably reject a qualification plan proposed
       by EMCORE.  JDSU shall not be obligated to accept such engineering change
       for Product  supplied to JDSU if such  Product has not been  qualified as
       described  in the  immediately  preceding  sentence  or  approved by JDSU
       customers. Until the Product has been so qualified,  EMCORE will continue
       to  manufacture  Product  ordered  pursuant  to  this  Agreement  without
       incorporating  the  engineering  changes that are in the process of being
       qualified.  JDSU  shall  accept  supply of all  Product  containing  such
       engineering  change  that  have been  qualified  in  accordance  with the
       foregoing  qualification  plan. In addition,  EMCORE may issue  mandatory
       engineering  changes  such as those  required to minimize  environmental,
       health or safety risks or as mandated by law provided that JDSU shall not
       be obligated  to purchase  for its own account or sell any Products  that
       fail to conform materially with performance, reliability or form, fit and
       function of the agreed specifications.

6.9    JDSU shall be permitted to request changes to the  Specifications  during
       the term of this  Agreement by giving  EMCORE  notice  regarding any such
       Performance  Specification  change.  The  parties  shall  thereafter  use
       reasonable  efforts to  develop,  within  four (4) weeks,  a  development
       program to implement such Performance Specification change and a mutually
       acceptable  qualification  plan for Product  containing such  Performance
       Specification  change. EMCORE shall not unreasonably reject a Performance
       Specification plan proposed by JDSU provided such Specification change is
       technically  practicable and such Specification change will not adversely
       affect the economic  benefits and  obligations of EMCORE pursuant to this
       Agreement.  Until the  Specification  change has been implemented and the
       Product  incorporating such revised  Specification has been so qualified,
       EMCORE will  continue to  manufacture  and JDSU will  continue  either to
       purchase  for its own account or sell  Product  ordered  pursuant to this
       Agreement  without  incorporating  any such JDSU requested  Specification
       change that is in the process of being qualified.

7.     Sales and Marketing

7.1    Subject to  oversight  by the  Steering  Committee,  JDSU shall be solely
       responsible  for all  Product  marketing  and  sales  related  activities
       including,  but not limited to,  providing  account  management  for each
       account,  preparing and  coordinating  all  advertising  and  promotional
       efforts,   training  and  deploying   qualified  sales   representatives,
       maintaining  a competent  customer  service and support  facility for the
       Products   consistent   with  JDSU's  other   products  and  systems  and
       maintaining  appropriate  press and media  relations.  In addition,  JDSU
       shall provide EMCORE with application  engineering  support as reasonably
       required.

7.2    EMCORE,  at its sole  cost,  shall  provide  small  quantities  of sample
       Products to JDSU from time to time to facilitate promotional  activities,
       subject to the review and approval of the Steering Committee.


8.     Commissions; Pricing; Minimum Volumes.

8.1    EMCORE shall pay JDSU a commission  on the sale of all Products  that are
       subject to Section 2.4 of this  Agreement  and for which EMCORE  receives
       sales revenue directly from the customer.  JDSU's commission shall be set
       by the Steering  Committee on the basis of the average  selling price for
       such  Product  and shall be payable  from the gross  revenue  received by
       EMCORE from sales to third party customers.  The Steering Committee shall
       review the  commission  payable to JDSU for each Product at its quarterly
       meetings;  provided,  however,  that the  Steering  Committee  shall only
       adjust JDSU's  commission  if (i) the average  selling price of a Product
       has decreased; (ii) EMCORE has experienced a material ({redact}) increase
       or decrease in its  manufacturing  costs, or (iii) JDSU has experienced a
       material  ({redact})  increase or decrease  in its sales,  marketing  and
       support costs. In the event that the Steering  Committee  cannot agree on
       JDSU's commission for a particular Product at any time during the term of
       the Agreement,  the Parties agree that:  (i) any {redact}  obligations of
       the  Parties  set forth in Section  2.4 above  shall not apply  until the
       Parties agree on commission; and (ii) existing commissions shall continue
       to apply for the  remaining  term of the  Agreement (or until the Parties
       agree on  alternative  commissions)  with  respect  to all  sales of such
       Product made through JDSU (it being understood that no commissions  shall
       be payable to JDSU for sales not made through  JDSU);  provided  that the
       Party  wishing  to invoke  this  provision  shall  give the  other  Party
       {redact} days prior written notice.  The Parties agree that at least with
       respect to the Initial  Product,  JDSU shall  conduct all  marketing  and
       sales on a commission basis.

8.2    In order to meet its Minimum Volume  Requirement  and for sales of Future
       Products,  JDSU may purchase  Product  directly from EMCORE for resale to
       customers.  The price of the Initial  Product for sales to JDSU  {redact}
       shall be set by the Steering  Committee.  The wholesale and retail prices
       for each of the Initial Product and any Future Products,  when set by the
       Steering  Committee,  shall remain fixed for a period of three (3) months
       and shall be established, to the extent reasonably practicable, {redact}.
       The Steering  Committee  shall review the pricing for each Product at its
       quarterly meetings;  provided, however, that the Steering Committee shall
       only adjust the {redact} pricing {redact}. In the event that the Steering
       Committee  cannot  agree on  pricing  at any time  during the term of the
       Agreement, the Parties agree that (other than with respect to the Initial
       Product):  (i) existing pricing shall continue to apply for the remaining
       term  of the  Agreement  (or  until  the  Parties  agree  on  alternative
       pricing);  and (ii) any {redact}  obligations of the Parties set forth in
       Section 2.4 above  shall not apply  until the  Parties  agree on pricing;
       provided that the Party wishing to invoke this  provision  shall give the
       other Party {redact} days prior written notice.

8.3    Any  withholding  or  other  taxes  that a Party  is  required  by law to
       withhold or pay on behalf of the other  Party shall be deducted  from any
       payments owed to such Party provided,  however, that in regard to any tax
       so deducted the remitting Party shall furnish the other Party with proper
       evidence of the taxes paid on its behalf and will furnish the other Party
       with  appropriate  documents to secure  application of the most favorable
       rate of withholding tax under applicable law.

8.4    Each Party shall initially apply its internal  accounting  principles and
       methodology in determining its Gross Margins,  Gross Revenues and product
       costs and  expenses  relating  to the  Shared  Research  and  Development
       Expenditures.  These internal accounting  principles and methodology must
       be  consistent  with  U.S.  Generally  Accepted  Accounting   Principles,
       consistently  applied  ("GAAP")  and shall be  reviewed  by the  Steering
       Committee prior to the Commercial Launch Date of the Initial Product.  If
       the Steering  Committee  disagrees  as to the  accounting  principles  or
       methodology  adopted  by a Party,  it shall  request  such  Party to make
       necessary changes or adjustments. If the Party objects to such changes or
       adjustments,  it may  request  that  an  independent  accounting  firm be
       chosen,  at its own expense,  by both Parties to make the final decision.
       The accounting  principles  and  methodology of any Party approved by the
       Steering  Committee or decided by an independent  accounting firm, as the
       case  may be,  shall  be  consistently  applied  during  the term of this
       Agreement.  The internal accounts (the "Internal  Accounts")  prepared by
       each Party applying its internal  accounting  principles and methodology,
       as reviewed by the Steering Committee,  must be submitted to the Steering
       Committee  for review on a quarterly  basis after the  Commercial  Launch
       Date as to  each  Product.  If a  Party  objects  to any  changes  to its
       Internal Accounts proposed by the Steering  Committee the matter shall be
       resolved pursuant to the dispute resolution provisions of Section 4.8 and
       Section 21.

8.5    Each Party shall  maintain  complete  and  accurate  books and records in
       connection with its research and development  expenditures  and its costs
       and  expenses in  connection  with  manufacture  and sale of the Product,
       including  relating to the  design,  development,  promotion,  marketing,
       distribution  and  selling of the  Products.  Upon a  reasonable  written
       request of one Party,  the other  Party  shall  permit the first Party to
       inspect or to use an independent  accounting  firm to audit, in each case
       at the first  Party's  own  expense,  the books and records of the second
       Party to evaluate whether its reporting  {redact} are accurate.  Should a
       discrepancy be found that resulted in an  underpayment  to the inspecting
       Party of greater than {redact}  percent  ({redact} %), the entire cost of
       the audit will be paid by the  audited  Party in  addition to any amounts
       owed by the audited Party but which were unpaid.

9.     Intellectual Property

9.1    All  Background  shall remain the absolute  unencumbered  property of the
       owner of such  rights  at the  Effective  Date.  No Party  will  make any
       representation  or do any act which may be taken to indicate  that it has
       any right title or interest in or to the  ownership  or use of any of the
       Background  of the other Party except under the terms of this  Agreement,
       and each Party  acknowledges  that nothing  contained  in this  Agreement
       shall give it any right, title or interest in or to the Background of the
       other Party save as granted hereby.

9.2    All  Foreground  generated by a Party (or by a Party and a third party in
       the course of a research  project  funded by such Party) shall remain the
       absolute unencumbered property of such Party.

9.3    Each Party hereby grants to the other Party a non-exclusive, royalty free
       license to use that Party's Background and Foreground for the purposes of
       performing its share of work under any Program. JDSU hereby grants EMCORE
       a  non-exclusive,   royalty  free  license  to  use  its  Background  and
       Foreground for the purpose of manufacturing  and having  manufactured the
       Products in the  Territory.  EMCORE hereby  grants JDSU a  non-exclusive,
       royalty free license to use its Background and Foreground for the purpose
       of marketing and selling  Products in the  Territory  (but not to import,
       manufacture or have  manufactured for sale in the Territory).  Each Party
       agrees  that,  subject to  Section  9.4,  it will not use the  Background
       and/or  Foreground  of the other  Party for any  purpose  other  than the
       performance of its obligations hereunder.

9.4    Upon  termination  of this Agreement or if at any time during the term of
       this Agreement the collaboration  between the Parties becomes {redact} by
       virtue of Sections  2.5,  2.6 or 2.7 hereof and subject to the payment of
       royalties as provided in Section 9.5 below,  each Party shall be entitled
       to a  royalty  bearing,  non-transferable  right  and  license  under the
       Intellectual  Property (including  Background and Foreground) and Company
       Information  (including all marketing  information and customer lists) of
       the other  Party to  manufacture,  have  manufactured,  promote,  market,
       distribute and sell Products  throughout the world;  provided that, where
       the  Agreement is  terminated  by reason of breach of one Party then that
       Party shall not be entitled to any  license as  aforesaid;  and  provided
       further that JDSU shall not be entitled to any right or license under any
       Intellectual Property of EMCORE relating to VCSEL or MOCVD technology and
       shall not be entitled to a license to manufacture or have manufactured an
       EMCORE Developed Product.  As a condition to the exercise of any right of
       a Party  hereunder  to have a third  party  manufacture  any portion of a
       Product,  such third  party  shall be bound by a written  confidentiality
       agreement as to any confidential  information of the licensing party that
       is no less  restrictive  in any material  respect  than the  restrictions
       contained in Section 11 hereof.

9.5    Royalties  payable under the licenses  granted in accordance with Section
       9.4 shall be based on net sales, shall be applied on a Product-by-Product
       basis and shall be set at a fair market value rate.  No royalty  shall be
       payable under any such license  until the licensee  under the license has
       first recouped  through profits  obtained by sales of licensed  Products,
       its research and development costs incurred under this Agreement.

9.6    The Parties shall, when appropriate, execute a formal license or licenses
       for the purpose of registering the licenses  granted pursuant to Sections
       9.3 or 9.4 above in such form as may be  necessary to give effect to this
       Agreement in any part of the  Territory  and to conform with any existing
       laws.  Such  license  or  licenses  shall be subject to all the terms and
       conditions of this Agreement.

9.7    Where  Foreground is generated  jointly by one or more  employees of each
       Party or by  employees  of a third  party on their  behalf  pursuant to a
       research project approved by the Steering Committee and funded as part of
       the Shared Research and Development Expenditures, it shall vest in and be
       the property of EMCORE and JDSU jointly unless in any particular case the
       Parties shall  otherwise  agree.  Subject to the rights of the Parties in
       any Background,  each Party shall have the irrevocable right,  subject to
       the  restrictions  contained in Section 2.4, to use such joint Foreground
       independently  of the other and  without  accounting  and,  to the extent
       necessary  for such use, is hereby  granted a royalty free license  under
       all jointly held Intellectual Property.

9.8    EMCORE  and JDSU shall  decide  through  the  mechanism  of the  Steering
       Committee  which of the  Parties  shall be  responsible  for  filing  and
       prosecuting  of any joint  patent  applications  in  connection  with any
       jointly owned  Foreground and of maintaining  any patents granted thereon
       in all countries and shall,  unless otherwise  agreed,  share equally all
       costs involved.

9.9    In the event that either Party becomes aware of an infringement of any of
       the Intellectual  Property licensed under this Section 9 or of any action
       by a third person for a declaration that any of the Intellectual Property
       is invalid or  unenforceable or of any infringement of a Party's right to
       sell hereunder,  it shall promptly notify the other Party in writing. The
       Parties shall cooperate in determining the appropriate action to be taken
       against the third party.  The Parties shall cooperate with each other and
       provide all necessary and  reasonable  assistance in any of such actions.
       EMCORE  shall select the outside  counsel to represent  the Parties in an
       infringement or other action.  Each Party may also retain its own outside
       counsel at its own  expense.  If any  infringement  or other  appropriate
       action is jointly instituted  pursuant to this Section,  the Parties each
       shall bear its  own-out-pocket  expenses and share  litigation  costs and
       legal fees equally. In the event of such a joint action, the Parties will
       share equally in any recovery of damages or amount paid in settlement. In
       the event that either Party institutes action  independently  pursuant to
       this  Section,  such Party shall be entitled to retain all  recoveries or
       settlements in connection therewith.

9.10   Upon termination of this Agreement, other than by reason of breach, or if
       at any time during the term of this Agreement the  collaboration  between
       the  Parties  becomes  {redact}  by virtue of  Sections  2.5,  2.6 or 2.7
       hereof,  each Party agrees, to the extent it has available  capacity,  to
       supply to the other Party any  Products  (other than an EMCORE  Developed
       Product) and any components or parts  manufactured by that Party that are
       used in the  manufacture  of  Products  (other  than an EMCORE  Developed
       Product),  and,  for a  {redact}  period  commencing  on the date of such
       termination  or  {redact},  such supply  shall be on a {redact}  basis as
       provided  in this  Section  9.10 for so long as that Party  continues  to
       manufacture such Product or components or parts in commercial  quantities
       for resale to third parties. {redact} terms shall be based only on actual
       sales by a Party to a third party of the same or equivalent components or
       parts and shall not be applied  retroactively  to any components or parts
       previously  shipped by a Party to another Party.  A Party  purchasing any
       component or part on {redact}  terms  pursuant to this Section 9.11 shall
       be required to purchase  equivalent  quantities  and accept all  material
       commercial terms as such third party {redact}.

       existing and/or  registered as applicable  under the laws of the relevant
       jurisdiction  and that it has the full  power  and  authority  to own and

       or proprietary rights to any Intellectual Property licensed hereunder.

10.14  EXCEPT AS EXPRESSLY SET FORTH HEREIN,  NEITHER PARTY MAKES ANY EXPRESS OR
       IMPLIED  WARRANTIES,   STATUTORY  OR  OTHERWISE,  CONCERNING  THE  VALUE,
       ADEQUACY,   FREEDOM   FROM   FAULT   OF,   OTHER   QUALITY,   EFFICIENCY,
       CHARACTERISTICS  OR  USEFULNESS  OF OR  MERCHANTABILITY  OR FITNESS FOR A
       PARTICULAR PURPOSE OF ANY PRODUCTS,  COMPONENTS OR SUBCOMPONENTS  THEREOF
       OR ANY  INFORMATION,  MATERIALS OR RIGHTS PROVIDED  HEREUNDER,  PROVIDED,
       HOWEVER,  THAT  NOTHING  IN THIS  ARTICLE  SHALL BE DEEMED A WAIVER OF OR
       DEEMED TO LIMIT THE  OBLIGATIONS  OF EACH  PARTY  HEREUNDER  OR UNDER ANY
       OTHER AGREEMENT BETWEEN THE PARTIES.

11.    Confidentiality

11.1   Each Party acknowledges that all the Company Information,  Background and
       Foreground provided by the other Party is confidential and proprietary to
       the other Party and further that the  information  developed by either or
       both  Parties  during the term of this  Agreement,  which  relates to the
       research,  development,  marketing or sales of a Product shall be treated
       as confidential  information  and agrees to maintain such  information in
       confidence during the term of this Agreement and for a period of five (5)
       years  thereafter and to use such  information  solely for the purpose of
       performing its respective obligations hereunder. The obligation set forth
       above shall be satisfied  by each Party  through the exercise of the same
       degree of care used to restrict disclosure and use of its own information
       of like  importance,  but in any  event at least a  reasonable  degree of
       care.


11.2   Each of EMCORE and JDSU  covenants  that it shall not  disclose  any such
       information to a third party except to its employees, agents or any other
       person under its  authorization,  on a need to know basis,  provided such
       employees,  agents  or person  under its  authorization  are  subject  in
       writing to the same confidentiality obligations as either EMCORE or JDSU,
       as the case may be.

11.3   Notwithstanding  anything  provided above, the  restrictions  provided in
       this section shall not apply to the information that is:

       11.3.1 already in the public  domain as of the date of  execution of this
              Agreement, or thereafter enters the public domain through no fault
              of the receiving Party;

       11.3.2 known to the receiving Party without restriction when received;

       11.3.3 received by either EMCORE or JDSU on an unrestricted basis whereby
              the  receiving  Party  has no  duty  of  confidence  to the  Party
              providing such information; or

       11.3.4 is required to be disclosed to a governmental or other  regulatory
              authority to the extent that such is required by applicable  laws,
              regulations  or court orders of the  applicable  jurisdiction,  in
              which case the disclosing  Party shall  promptly  notify the other
              Party of such disclosure.

11.4   Each  Party   acknowledges   that  damages  resulting  from  unauthorized
       disclosure of the Company Information,  Foreground or Background would be
       an inadequate  remedy and that in the event of any such  disclosure,  the
       other  Party  shall  be  entitled  to seek  injunctive  relief  or  other
       equitable relief in addition to any and all remedies  available at law or
       in equity,  including the recovery of damages and  reasonable  attorneys'
       fees.

11.5   Upon  termination  of this  Agreement,  each Party shall cease use of the
       Company  Information,  Foreground and Background  received from the other
       Party (other than as expressly  permitted hereby),  and shall destroy all
       copies of same with written certification of destruction.  Alternatively,
       at the request of the originating Party, the receiving Party shall return
       all such information and copies to the originating Party.

12.    No Assignment, Sub-Licenses and Sub-Contracts

12.1   Except for the right of the Parties to assign to their parent corporation
       or  wholly  owned  Affiliate  and  except  for the  delegation  of duties
       expressly  permitted  hereby,  neither  EMCORE nor JDSU may  assign  this
       Agreement  or  any  of  its  rights,  interests,  duties  or  obligations
       hereunder   without   prior   written   consent   of  the  other   Party.
       Notwithstanding  the foregoing,  either Party, may, without obtaining the
       prior  written  consent  of the  other  Party,  assign or  transfer  this
       Agreement or delegate any rights or  obligations  hereunder in connection
       with merger,  reorganization,  transfer, sale of assets or product lines,
       or change  of  control  or  ownership  of such  Party,  or its  permitted
       successors, assigns or transferees; provided, however that, prior to such
       assignment  or transfer,  such Party shall provide the other Party hereto
       with  reasonable  assurances  that the performance of all of such Party's
       obligations  hereunder  shall continue after such assignment or transfer.
       Such assurances shall include, without limitation, reasonable assurances,
       form  EMCORE  that JDSU shall  continue to receive its supply of Products
       hereunder,  or reasonable assurances from JDSU that EMCORE shall continue
       to receive timely  payments as required under any purchase  orders.  This

              such breach;

              insolvent by any court of competent  jurisdiction,  any trustee or
              receiver is appointed for it or for any of its  property,  or such
              Party  files any  involuntary  petition  under any  bankruptcy  or
              similar  law  providing  for  its   reorganization,   dissolution,
              liquidation or winding-up.

13.3   Either  Party shall have the right to  terminate  this  Agreement  if the
       Commercial  Launch  Date  for the  Initial  Product  does  not  occur  by

13.4   Termination of this Agreement for all or any part of the Territory  shall
       be without  prejudice  to any rights of either  Party  against  the other
       which may have accrued up to the date of such termination,  including the
       right to claim damages or pursue injunctive relief.

13.5   In  particular,  termination  of this  Agreement for any reason shall not
       bring to an end the rights and  obligations of the Parties under Sections

       of which  shall  survive  any  termination  of this  Agreement  except as
       otherwise expressly provided herein.

14.    Force Majeure

       Party  specifying  the  matters  constituting  the  Force  Majeure  Event
       together with such evidence as it reasonably  can give and specifying the

       continue  then the Party so  prevented  or delayed  shall be excused  the
       performance  as from the date of such notice for so long as such cause or

       days' written  notice of such  termination  to the other Party,  but such

       this Agreement.
