                            [FIBERCORE INC. GRAPHIC]

                         OPTICAL FIBER SUPPLY AGREEMENT

      This Optical Fiber Supply Agreement (this "Agreement") dated as of
December 18, 2000 is by and between COMMSCOPE, INC. OF NORTH CAROLINA, a North
Carolina corporation ("CommScope") and FIBERCORE, INC., a Nevada corporation,
and its subsidiaries and affiliates (collectively, "FiberCore").

                              BACKGROUND STATEMENT
                              --------------------

      The parties desire to establish the terms, conditions and procedures
pursuant to which FiberCore shall agree to supply to CommScope, and CommScope
shall agree to purchase from FiberCore single and multimode optical fiber during
the term of this Agreement.

                                    AGREEMENT
                                    ---------

      Now, therefore, the parties hereto agree for themselves, their successors
and permitted assignees as follows:

      1.  Purchase and Supply Commitment; Products.

      1.1 During the term of this Agreement and subject to the terms hereof,
FiberCore agrees to supply CommScope's needs for single and multimode optical
fiber, as described on Appendix A (the "Products") in accordance with the
quantities and delivery schedule set forth on Appendix B. The terms and
conditions of this Agreement shall apply to each sale by FiberCore to CommScope
of the Product during the term hereof. The parties may add additional products
to Appendix A by mutual written agreement, and such additional products shall be
considered "Products" hereunder and subject to the terms and conditions hereof.
CommScope agrees that Products purchased under this Agreement are for its own
manufacturing use.

      1.2 The current specifications for the Products are set forth on Appendix
C (the "Specifications"). The Specifications may be amended from time to time
upon the agreement of both parties to address new functional and market
requirements. However, any substantial modifications to the Specifications, as
agreed to in writing, may result in a per kilometer price increase or decrease
(as agreed by the parties in writing) for the year of such adjustment and for
any subsequent period hereunder. For maximum responsiveness to competitive fiber
product offerings, FiberCore reserves the right, in its sole discretion, to make
any changes it deems desirable in the design or manufacture of the Products;

<PAGE>

provided that that Products, as modified, meet the then current Specifications
and the requirements that pertain to the ability of CommScope to manufacture
cable.

      1.3 FiberCore shall deliver the quantity of the Product ordered on the
delivery dates set forth on Appendix B and in conformity to the Specifications.

      2. Term. The initial term of this Agreement is three (3) years, commencing
on January 1, 2001. Upon expiration of the initial term, this Agreement shall
automatically renew for consecutive three (3) year renewal terms (or any other
mutually acceptable renewal term), unless either party gives notice of
nonrenewal and a request to renegotiate to the other party pursuant to SECTION
20 at least six (6) months prior to the expiration of the then current term.

      3. Delivery Schedule. Appendix B sets forth the monthly shipping schedule
for the Products. CommScope may request reasonable changes in the shipping
schedule. All requests must be received sixty (60) days prior to the requested
change(s) and approved by FiberCore in writing, which approval shall not be
unreasonably delayed or withheld.

      4. Pricing.

      4.1 Effective as of the date hereof, prices for the Products shall be
determined as set forth on Appendix D attached hereto and incorporated herein.
Prices for multimode optical fiber shall be effective as of January 1, 2002.
Prices for single-mode optical fiber shall be effective as of January 1, 2001.
Appendix D, together with SECTION 4.4 hereof, establishes maximum prices for the
Products.

      4.2 In each calendar year subsequent to 2001 during which this Agreement
is in effect, the parties shall meet in September of the preceding year to
review and discuss pricing, with the objective of ensuring that the price being
charged to CommScope for the Products is competitive and no more than the
average price CommScope would pay during such subsequent year to "Primary
Producers" for similar quantities of the Products (the "Market Price"). For
purposes of this Agreement, the term "Primary Producers" shall include Alcatel,
Lucent and Corning.

      4.3 After Product pricing has been fixed for a calendar year, Appendix D
shall be amended accordingly and the agreed Product pricing for a calendar year
shall remain fixed for the duration of that calendar year, subject to the right
of CommScope or FiberCore to request a semi-annual pricing review with the
objective of ensuring that the price being charged to CommScope for the Products
is competitive and reflects market conditions. FiberCore's raw material costs
shall also be considered at each semi-annual review.

      4.4 The prices to be paid by CommScope for Products hereunder shall not at
any time be greater than the price paid by any of FiberCore's other customers
for the same type and similar quantity of Products. CommScope may request that
FiberCore certify that it is not selling Products of the same type and similar
quantity to any of FiberCore's other customers at a price that is lower than
that paid by CommScope.

      4.5 CommScope may request FiberCore to consider project-specific pricing
for any CommScope project that reasonably requires a different pricing
arrangement for the Products. FiberCore shall consider any such request in good

                                       2

<PAGE>

faith and shall work cooperatively with CommScope in seeking to negotiate a
mutually acceptable pricing arrangement for any such project. CommScope will
make a good faith effort to provide reasonable evidence of the need for
alternative pricing.

      5. Shipment Terms. Shipment terms are delivered duties paid ("DDP") from
shipping origin of either Brazil or Jena to destination CommScope/Claremont, NC.
These terms constitute a fully landed cost door to door with all expenses paid
by FiberCore. CommScope may, at its option (a) physically pick up Product at
FiberCore's factory loading dock upon reasonable notice, (b) arrange for pick up
via common carrier at FiberCore's factory loading dock upon reasonable notice,
or (c) request that FiberCore act as CommScope's agent to arrange delivery of
Product. If CommScope requests that FiberCore act as CommScope's agent, then
FiberCore shall have the right to designate the method of transportation,
carrier and route of shipment. Title and risk of loss shall pass to CommScope at
the DDP point set forth above.

      6. Payment Terms;"Take or Pay". CommScope agrees to purchase, and
FiberCore agrees to sell single-mode optical fiber, as follows: (i) 205,000 km
in 2001; (ii) up to 1,000,000 km in 2002, as described on Appendix B and (iii)
up to 1,000,000 km in 2003, as described on Appendix B. CommScope expects to
purchase such quantities of single-mode optical fiber in accordance with the
delivery schedule set forth on Appendix B, and FiberCore will issue invoices in
accordance with actual deliveries for each calendar month. All invoices will be
due within thirty (30) days from CommScope's receipt of such invoice. CommScope
shall receive a one percent (1%) discount on any invoice paid within ten (10)
days from the date of CommScope's receipt of the invoice. Payment shall be made
by any payment method approved by both parties to an account designated by
FiberCore. Unless CommScope's performance is excused by SECTION 16 hereof, if
CommScope fails to purchase, on an annual basis, the quantities of single-mode
optical fiber specified above for either 2001, 2002 or 2003 that FiberCore
delivers, then CommScope agrees to pay FiberCore an amount equal to the
"remaining dollar value" of this Agreement for such year, multiplied by one
hundred percent (100%) for 2001, seventy-five percent (75%) for 2002 or
seventy-five percent (75%) for 2003. For purposes of this Agreement, the term
"remaining dollar value" shall equal the quantity of single-mode optical fiber
set forth above for the applicable year that is not purchased by CommScope under
this Agreement, multiplied by the last price of such Product shipped by
FiberCore to CommScope.

      7. Order Terms. Any terms of any forecast, purchase order, order
confirmation, invoice or acknowledgment, if any, of either party that are in
addition to the terms of this Agreement shall be effective only if accepted by
the other party in writing.

      8. Approved Supplier Status.

      8.1 In order to maintain its designation as an "approved supplier" of
CommScope, FiberCore shall maintain a 99.85% quality acceptance level for
single-mode optical fiber and a 99.85% quality acceptance level for multimode
optical fiber (i.e., furnish Products that meet CommScope's raw material and
cable specifications and are not subject to rejection). CommScope shall
reasonably calculate FiberCore's quality acceptance level monthly in accordance
with CommScope's procedures to be mutually agreed upon between the parties, and
shall notify FiberCore of the result and CommScope's determination shall be

                                       3

<PAGE>

conclusive. In the event FiberCore is below 99.85% acceptance on an aggregate
basis for single-mode and/or multimode optical fiber in any period of three (3)
consecutive months, FiberCore shall be placed on a quality alert status. In the
event FiberCore is below 99.85% acceptance on an aggregate basis for single-mode
and/or multimode optical fiber in any period of six consecutive months, then
FiberCore shall lose its designation as an "approved supplier" of CommScope. In
that event, FiberCore would be placed on experimental status until reapproval
could be established by CommScope's Materials Engineering, Quality Assurance,
and Purchasing Divisions.

      8.2 To maintain approved supplier status, FiberCore must provide a
corrective action program that is capable of resolving quality problem issues in
a manner reasonably acceptable to CommScope. The corrective action program
should be practical and capable of identifying a problem and defining measurable
correction to the non-conformity. The corrective action taken will be audited
periodically at FiberCore's facility in connection with CommScope's Supplier
Quality Audit.

      8.3 FiberCore shall maintain appropriate records regarding Product
testing, evaluation and quality compliance, and shall furnish such records
promptly to CommScope at CommScope's request. FiberCore personnel shall meet
quarterly with CommScope personnel to discuss appropriate issues related to
Product quality

      9. Technical Support. During the term hereof, FiberCore shall furnish such
technical support services to CommScope in connection with the Products sold
hereunder, as well as fiber optical cable incorporating the Products and/or any
other products purchased from FiberCore, as CommScope reasonably requests
including, without limitation: (a) technical and quality reviews at least
quarterly and (b) on-site support for CommScope's engineers as requested by
CommScope on a reasonable frequency. Such services shall be provided at
FiberCore's expense, unless otherwise specifically agreed to in writing by the
parties.

      10. Sales Support. During the term hereof, FiberCore shall cause its sales
personnel to participate with CommScope on sales calls relating to optical fiber
cable produced using the Products, as reasonably requested by CommScope. Any
expenses of FiberCore's sales personnel shall be paid by FiberCore.

      11. Warranty.

      11.1 Warranty and Warranty Period. FiberCore warrants that the Products
shall comply with the Specifications and shall otherwise be free from defects in
design, materials and workmanship for a period of twelve (12) months as of the
date of delivery under standard conditions of storage at ambient temperature
between 10(degree)C and 30(degree)C and at a rate of humidity between thirty
percent (30%) and eighty percent (80%). Except as otherwise stated in this
SECTION 11 or in SECTION 12, FiberCore makes no warranties, express or implied,
and specifically disclaims any warranty of merchantability or fitness for any
particular purpose as well as other implied warranties in law or equity.

      11.2 Refund; Replacement. If any Product is found to breach any of the
warranties set forth above, FiberCore shall, at its option, either give
CommScope a refund for such defective Product or replace the defective or
non-conforming Product with new Product that conforms to the Specifications and

                                       4

<PAGE>

is free from defects in design, materials and workmanship, at no additional cost
to CommScope, delivered to the same destination as that of the original
shipment. All such replacement Products shall be warranted for the balance of
the warranty period. FiberCore's obligation to refund or replace is conditioned
upon (i) the receipt of proper and timely notice, as specified in SECTION 11.3
below, (ii) an examination that reveals the claimed defect actually exists and
(iii) the Product shall not have had any stage of processing performed on it for
cabling. Samples must be provided for evaluation prior to any Product being
returned for credit and/or replacement.

      11.3 Notice. In order for the foregoing warranty to be effective,
CommScope must notify FiberCore, in writing, within a reasonable time (but in
any event not later than thirty (30) days from the end of the warranty period)
of any defects referred to in SECTION 11.1 hereof. The issuance of a refund or
the replacement of defective or non-conforming Product in accordance with the
provisions of this warranty shall be in full satisfaction of FiberCore's
liabilities arising from the defect.

      12. Intellectual Property Warranty and Indemnity. FiberCore warrants that
it owns or has a right or license in all of the patents and other intellectual
property rights required: (i) to manufacture and sell the Product to CommScope
and (ii) for CommScope to use the Products for their intended use and to sell to
its customers products incorporating the Products. FiberCore agrees that it
shall, at its own expense and to the extent hereafter stated, indemnify, defend
and hold CommScope and its customers harmless in any dispute, suit or proceeding
(including any claim for temporary or permanent injunctive relief) insofar as
the same is based on a claim that any Product furnished hereunder, or the use
thereof for its intended purpose, infringes any United States or foreign patent
or other intellectual property right of any person throughout the world.
FiberCore's obligations are conditioned upon CommScope's delivery to FiberCore
of prompt notice of any such dispute, suit or proceeding and permission to allow
FiberCore through its counsel to defend the same. CommScope shall cooperate with
FiberCore in such defense or settlement negotiations and shall provide FiberCore
with any reasonably requested information and assistance, at FiberCore's sole
expense. Unless FiberCore does not defend (for reasons other than described
below under which FiberCore has no obligation to defend) any such suit or
proceeding after being given reasonable notice of and opportunity to defend the
same, CommScope shall not make any admission of infringement or settle the suit
or proceeding without FiberCore's consent.

      Notwithstanding the foregoing, FiberCore shall have no obligation to
defend or settle any claim for any infringement or violation of any patent or
other intellectual property right (i) arising solely from compliance with
CommScope's Specifications, but only to the extent such Specifications are in
addition to or different from those Specifications set forth on Appendix C and
are different from or exceed FiberCore's standard specifications for the Product
or (ii) relating to the combination of any Product furnished hereunder with any
other product, whether or not furnished by FiberCore, for use in the manufacture
of fiber optic cable or other CommScope product.

      FiberCore hereby represents and warrants that it does not hold or have the
right to use any patents or licenses related to the combination or use of the
Products in the manufacture of fiber optic cable; provided, however, that
FiberCore agrees to provide, within fifteen (15) days of receiving such

                                       5

<PAGE>

information, written notice to CommScope of any patents or licenses, whether
held by FiberCore or any third party, relating to the combination or use of the
Product in the manufacture of fiber optic cable.

      13. Limitation of Liability.

      13.1 Exclusion of Consequential Damages. Neither party shall be liable to
the other for any indirect, incidental, special, punitive or consequential loss,
damage or expense (which shall include any loss of profit or revenue, any loss
of goodwill, any loss of business opportunity, of any nature or kind, however
arising, whether in contract, in tort or otherwise, even if such party is deemed
to be aware of the possibility of such damages). No action against FiberCore
with respect to any Product may be commenced more than twelve (12) months after
such Product was delivered to CommScope. The limitations set forth in this
SECTION 13.1 shall not apply to any breach of the warranty set forth in SECTION
11 or SECTION 12.

      13.2 Limitation Valid in All Events. Each party acknowledges that rights
may be conferred upon it or obligations imposed upon it by the laws governing
this Agreement that cannot be excluded by agreement between the parties. To the
extent that such laws are applicable, the terms of this Agreement shall be read
subject to such laws and the parties hereby acknowledge that each party
expressly limits its liability under any such laws to the maximum extent
permitted.

      13.3 Maximum Liability. FiberCore's maximum total liability under this
Agreement whether based on breach of contract or in tort (including negligence)
under any warranty or otherwise shall in no event exceed $3,000,000; provided
that such limitation shall not apply to any breach of the warranties set forth
in SECTION 11 or SECTION 12 hereof.

      14. Confidential Information. The parties agree not to disclose to any
third party and not to use, except for the purpose of this Agreement, the terms
of this Agreement or any technical or commercial information of a confidential
nature made available to either of the parties by the other party or which
either party may have learned in the course of this Agreement, unless compelled
to disclose such information by judicial or administrative process or by other
requirements of law. All such information shall be returned to the disclosing
party at its request upon termination of this Agreement. The above provision
shall survive any termination of this Agreement and shall continue with respect
to any specific confidential information so long as that information remains
confidential and not available to the public (other than by unauthorized
disclosure by the party to whom such confidential information was disclosed).

      15. Termination.

      15.1 Either party shall have the right to terminate this Agreement
effective upon written notice to the other party in any of the following events:

            (a) If the other party fails to perform any of its material
      obligations under this Agreement, which failure is not cured within thirty
      (30) days following written notice of such failure from the terminating
      party, describing in reasonable detail the circumstances giving rise to
      such failure. Such failure could include, by example and without
      limitation, FiberCore's failure to deliver Products on time at least
      ninety percent (90%) of the time in any period of three (3) consecutive

                                       6

<PAGE>

      months in accordance with CommScope's delivery requirements, and
      CommScope's failure to pay any amount due to FiberCore pursuant to the
      terms hereof; and

            (b) If the other party suspends its business operations or becomes
      bankrupt or insolvent, or if a receiver or similar official is appointed
      for all or substantially all of its assets.

      15.2 In addition, CommScope may terminate this Agreement effective upon
written notice to FiberCore upon FiberCore's failure to maintain a quality
acceptance level for each of single-mode and multimode optical fiber in excess
of an aggregate of 99.85% in any period of six (6) consecutive months. CommScope
agrees to maintain the same general incoming quality inspection process for the
Term of this Agreement. Any material changes must be reviewed and approved by
FiberCore, which shall not unreasonably delay or withhold approval.

      16. Force Majeure. Neither party shall be responsible or liable for any
delay or failure to deliver or purchase any and all quantities agreed, if such
delay or failure is caused solely by an event beyond the reasonable control of
the party, including but not limited to, act of God, fire, flood, war,
insurrection, riot, action of any government agency or strike, late
delivery/commissioning of equipment, or further deterioration of current raw
material supply. In the event of the occurrence of any such event, FiberCore
shall apportion available supplies of the Products to CommScope in a
proportionate amount no less than CommScope's respective share of FiberCore's
business for the Products during the preceding one hundred eighty (180) day
period. At CommScope's option, in the event of delay in delivery because of any
such event, the delivery date shall be postponed for a period of time equal to
the duration of such cause.

      17. Notice. Unless specifically provided otherwise in this Agreement, all
notices required or permitted to be given under this Agreement shall be in
writing and shall be sent (i) by certified or registered mail, return receipt
requested, (ii) by hand delivery, (iii) by facsimile transmission, or (iv) by
nationally recognized overnight delivery service, and in each case shall be

                               FIRST AMENDMENT TO
                         OPTICAL FIBER SUPPLY AGREEMENT

      THIS FIRST AMENDMENT TO OPTICAL FIBER SUPPLY AGREEMENT (this "First
Amendment") is effective as of the 13th day of November, 2001, by and between
COMMSCOPE, INC. OF NORTH CAROLINA, a North Carolina corporation
("CommScope") and FIBERCORE, INC., a Nevada corporation, and its subsidiaries
and affiliates (collectively, "FiberCore").

                              BACKGROUND STATEMENT
                              --------------------

      The parties hereto previously entered into an Optical Fiber Supply
Agreement dated as of December 18, 2000 (the "Supply Agreement"), pursuant to
which FiberCore agreed to supply and CommScope agreed to purchase certain
quantities of single-mode optical fiber during the term of the Supply Agreement.
The parties now desire to modify and amend, in certain respects, the Supply
Agreement, in order to evidence the revised agreement between the parties.

                             STATEMENT OF AGREEMENT
                             ----------------------

      NOW, THEREFORE, in consideration of the mutual premises contained herein,
and other good and valuable consideration, the legal sufficiency of which is
hereby acknowledged, CommScope and FiberCore hereby agree as follows:

      1. The final sentence of Section 1.1 of the Supply Agreement is hereby
deleted.

      2. The first two (2) sentences of Section 6 of the Agreement are hereby
deleted and replaced with the following:

            "CommScope agrees to purchase, and FiberCore agrees to sell
            single-mode optical fiber, as follows: (i) 119,000 km in 2001
            (including previously purchased quantities); (ii) 55,000 km in 2002
            and (iii) up to 250,000 km in 2003. CommScope expects to purchase
            such quantities of single-mode fiber in accordance with the delivery
            schedule set forth on Appendix B and as specified from time to time
            in its purchase orders. In addition, CommScope agrees to purchase,
            and FiberCore agrees to supply, substantially all of CommScope's
            requirements for 62.5 i multimode fiber for 2002 and 2003, with a
            minimum purchase commitment for such fiber of 35,000 km for 2002 and
            40,000 km for 2003. CommScope's purchases of multimode fiber shall
            be in such quantities and for such delivery dates as specified by
            CommScope from time to time in its purchase orders. FiberCore will
            issue invoices in accordance with actual deliveries for each
            calendar month."

      3. A new paragraph is hereby added to the end of Section 6, as follows:

            "Notwithstanding any other provision of this Supply Agreement,
            during the term of this Supply Agreement, CommScope shall have no
            obligation to purchase from FiberCore, and CommScope may freely
            purchase from third parties: (i) any optical fiber for cable with
            respect to which the customer has specified that the optical fiber

<PAGE>

            must be supplied by another producer; (ii) any optical fiber
            requested by the customer with specifications that FiberCore does
            not have the technical capability or legal right to produce; (iii)
            any optical fiber that cannot be delivered to CommScope to enable
            it, exercising commercially reasonable efforts, to meet the time
            schedule of its customer; provided that with respect to the first
            and third exceptions, CommScope must use a good faith effort to
            convince its customers to order, accept and use cable incorporating
            FiberCore's fiber products instead of those of another fiber
            manufacturer and that with respect to the second exception,
            CommScope must use a good faith effort to convince its customers to
            order, accept and use Supplier's fiber products meeting the
            Specifications instead of those of another fiber manufacturer."

      4. Appendix B is hereby deleted in its entirety and replaced with the
attached Appendix B.

      5. Appendix D is hereby deleted in its entirety and replaced with the
attached Appendix D.

      6. FiberCore hereby waives any default or event of default that has
heretofore occurred as a result of CommScope not purchasing certain quantities
of single-mode fiber as required by the Supply Agreement and specifically
waives, without limitation, any right to payment pursuant to Section 6 of the
Supply Agreement.

      7. FiberCore agrees to continue to use its best efforts to sell
CommScope's quantities of single-mode fiber, including without limitation,
quantities purchased by CommScope in the fourth quarter of 2001, to other
customers, and agrees to reduce CommScope's future obligations hereunder, or to
issue credits against future purchases, to the extent such sales are
consummated.

      8. This First Amendment is limited as specified and shall not constitute
or be deemed to constitute an amendment, modification or waiver of any provision
of the Supply Agreement except as expressly set forth herein. All other terms
and provisions of the Supply Agreement shall continue in full force and effect
and unchanged and are hereby confirmed in all respects.

      9. All capitalized terms used herein without definition shall have the
meaning assigned to such terms in the Supply Agreement.

      10. This First Amendment shall be governed by and construed and enforced
in accordance with the laws of the State of North Carolina (without regard to
the conflicts of law provisions thereof). This First Amendment may be executed
in any number of counterparts, each of which when so executed and delivered
shall be an original, but all of which shall together constitute one and the
same instrument.

      11. This First Amendment will become effective when signed by all the
parties hereto.

                                       2

      12. Each party respectively represents and warrants that: (i) it has all
