1.03 Scope

       (a) The licenses granted herein are licenses to (i) make, have made, use,
lease, offer to sell, sell and import LICENSED PRODUCTS; (ii) make, have made,
use and import machines, tools, materials and other instrumentalities, insofar
as such machines, tools, materials and other instrumentalities are involved in
or incidental to the development, manufacture, testing or repair of LICENSED
PRODUCTS which are or have been made, used, leased, owned, sold or imported by
the grantee of such license; and (iii) convey to any customer of the grantee,
with respect to any LICENSED PRODUCT which is sold or leased by such grantee to
such customer, rights to use and resell such LICENSED PRODUCT as sold or leased
by such grantee (whether or not as part of a larger combination); provided,
however, that no rights may be conveyed to customers with respect to any
invention which is directed to (1) a combination of such LICENSED PRODUCT (as
sold or leased) with any other product, (2) a method or process which is other
than the inherent use of such LICENSED PRODUCT itself (as sold or leased), or
(3) a method or process involving the use of a LICENSED PRODUCT to manufacture
(including associated testing) any other product.

       (b) Licenses granted herein to IGC are not to be construed either (i) as
consent by the grantor to any act which may be performed by the grantee, except
to the extent impacted by a patent licensed herein to the grantee, or (ii) to
include licenses to contributorily infringe or induce infringement under U.S.
law or a foreign equivalent thereof.

       (c) The grant of each license hereunder includes the right to grant
sublicenses within the scope of such license to a Party's RELATED COMPANIES for
so long as they remain its RELATED COMPANIES. Any such sublicense may be made
effective retroactively, but not prior to the effective date hereof, nor prior
to the sublicensee's becoming a RELATED COMPANY of such Party.

       (d) The grant of each license hereunder also includes the right of a
Party to sublicense (within the scope of its own licenses) any business which is
divested by that Party or any of its RELATED COMPANIES provided that the
sublicense is granted within sixty (60) days of divestiture and the divested
business is itself a legal entity at the time of divestiture or within sixty
(60) days thereafter. Such sublicense may continue for so long as the divested
business remains a legal entity and shall extend only to the LICENSED PRODUCTS
[*] and only for the patents of the non-divesting Party [*]. Furthermore, any
sublicense shall not extend to the products sold or services furnished by a
third party which acquires the divested business, even if they are of the same
kind or similar to those of the divested business and even if made, sold or
provided by the divested business. Any payment obligations of a divesting Party
under this Agreement shall continue in effect for all LICENSED PRODUCTS,
including the LICENSED PRODUCTS of the divested business. The divested business
shall be jointly and severally liable with the divesting Party for the licensee
fees payable on account of the LICENSED PRODUCTS of the divested business.

1.04 Ability to Provide Licenses

       (a) LUCENT-GRL has received the rights to grant the licenses and releases
under LUCENT-GRL's PATENTS herein granted to IGC.

       (b) It is recognized that certain past actions of the Parties to this
Agreement, such as the assignment of title to any invention or patent, or the
granting of any licenses, may limit their ability to provide licenses hereunder.
In particular, prior to the execution of this Agreement, a Party may have
limited by contract its ability to provide licenses hereunder with respect to
certain patents or technologies. A Party's failure to meet any obligation
hereunder due to any such actions shall not constitute a breach of this
Agreement, provided that such assignment or granting of licenses was made for
bona fide business purposes and not for the purpose of frustrating or preventing
the grant of licenses hereunder.

       (c) A Party's failure to meet any obligation hereunder, due to the
assignment of title to any invention or patent, or the granting of any licenses,
to the United States Government or any agency or designee thereof pursuant to a
statute or regulation of, or contract with, such Government or agency, shall not
constitute a breach of this Agreement.

1.05 Joint Inventions

       (a) There are countries (not including the United States) which require
the express consent of all inventors or their assignees to the grant of licenses
or rights under patents issued in such countries for joint inventions.

       (b) Each Party shall give such consent, or shall obtain such consent from
its RELATED COMPANIES, its employees or employees of any of its RELATED
COMPANIES, as required to make full and effective any such licenses and rights
respecting any joint invention granted to the grantee hereunder by such Party
and by another licensor of such grantee.

       (c) Each Party shall take steps which are reasonable under the
circumstances to obtain from third parties whatever other consents are necessary
to make full and effective such licenses and rights respecting any joint
invention purported to be granted by it hereunder. If, in spite of such
reasonable steps, such Party is unable to obtain the requisite consents from
such third parties, the resulting inability of such Party to make full and
effective its purported grant of such licenses and rights shall not be
considered to be a breach of this Agreement.

forth in subsections (a) and (b) below.

       (a) An up-front license fee of [*] United States dollars (U.S. $[*]) that
is payable in two (2) installment payments as follows:

              (i)  a sum of [*] United States dollars (U.S. $[*]) payable upon

       (b) a licensee fee payable in warrants in the form of a grant to
Lucent-GRL of one hundred thousand (100,000) shares of IGC's Common Stock. Such
warrants are of the form attached hereto as Appendix C. The warrants are granted
to Lucent-GRL on the day both Parties sign this Agreement ("Grant Date"), which
shall not be later than July 14, 2000. Upon the issuance of the YBCO PATENT
APPLICATION as a United States patent, such warrants may be exercised at [*],
however, such warrants must be exercised not later than seven (7) years
following the Grant Date.

2.02 Payments

[*]. So long as the installment payments set forth in Section 2.01(a) are paid
in a timely manner to LUCENT-GRL, no late fee or interest shall be applicable.
Should such payments be considered overdue, however, then such payments shall be
subject to a late payment charge calculated at an annual rate of [*] over the
prime rate or successive prime rates (as posted in New York City) during
delinquency. If the amount of such charge exceeds the maximum permitted by law,
such charge shall be reduced to such maximum.

all breaches specified therein shall have been remedied.

3.02 Survival

made prior to the date of such cessation, shall not be affected by such
cessation.

       (b) Any termination of licenses and rights of a Party under the
provisions of this Article III shall not affect such Party's licenses, rights
and obligations with respect to any LICENSED PRODUCT made prior to such
termination, and shall not affect the other Party's licenses and rights (and
obligations related thereto) hereunder.


                                   ARTICLE IV

     (e)     [*]; and

performance, each by the other, and intend that, other than set forth in Section
1.03(d), the licenses and rights granted hereunder to a Party not be extended to
entities other than such Party's RELATED COMPANIES without the other Party's
express written consent. All of LUCENT-GRL's rights, title and interest in this
Agreement and any licenses and rights granted to it hereunder may be assigned to
any of its RELATED COMPANIES or any direct or indirect successor to the business
of LUCENT-GRL as the result of any internal reorganization, which successor
shall thereafter be deemed substituted for LUCENT-GRL as the Party hereto,
effective upon such assignment; but neither this Agreement nor any licenses or
rights hereunder shall be otherwise assignable or transferable (in insolvency
proceedings, by reason of a corporate merger, or otherwise) by either Party
without the express written consent of the other Party, which consent will not
be unreasonably withheld.


4.03 Addresses

       (a) Any notice or other communication hereunder shall be sufficiently
given to IGC when sent by certified mail addressed to ______________________

4.04 Taxes

related interest and penalties), however designated, imposed as a result of the
existence or operation of this Agreement, except (i) any tax imposed upon
LUCENT-GRL in a jurisdiction other than the United States if such tax is
allowable as a credit against the United States income taxes of LUCENT; and (ii)
any net income tax imposed upon LUCENT-GRL by the United States or any
governmental entity within the United States (the fifty (50) states and the
District of Columbia). In order for the exception contained in (i) to apply, IGC
must furnish LUCENT-GRL with evidence issued by the taxing authority in such
jurisdiction that such tax has been paid. The evidence must be furnished within
thirty (30) days of issuance by the taxing authority and must be sufficient to
satisfy United States taxing authorities that such tax has been paid.

<PAGE>


       (b) If IGC is required to bear a tax, duty, levy or similar charge
pursuant to (a) above, IGC shall pay such tax, duty, levy or similar charge and
any additional amounts as are necessary to ensure that the net amounts received
by LUCENT-GRL hereunder after all such payments or withholdings equal the
amounts to which LUCENT-GRL is otherwise entitled under this Agreement as if
such tax, duty, levy or similar charge did not apply.

4.05 Choice of Law

The Parties are familiar with the principles of New York commercial law, and
desire and agree that the law of New York, exclusive of its conflict of laws
provisions, shall apply in any dispute arising with respect to this Agreement.

4.06 Integration

This Agreement sets forth the entire agreement and understanding between the
Parties as to the subject matter hereof and merges all prior discussions between
them. Neither of the Parties shall be bound by any warranties, understandings or
representations with respect to such subject matter other than as expressly
provided herein or in a writing signed with or subsequent to execution hereof by
an authorized representative of the Party to be bound thereby.

4.07 Outside the United States

       (a) There are countries in which the owner of an invention is entitled to
compensation, damages or other monetary award for another's unlicensed
manufacture, sale, lease, use or importation involving such invention prior to
the date of issuance of a patent for such invention but on or after a certain
earlier date, hereinafter referred to as the invention's "protection
commencement date" (e.g., the date of publication of allowed claims or the date
of publication or "laying open" of the filed patent application). In some
instances, other conditions precedent must also be fulfilled (e.g., knowledge or
actual notification of the filed patent application). The Parties agree that (i)
an invention which has a protection commencement date in any such country may be
used in such country pursuant to the terms of this Agreement on and after any
such date, and (ii) all such conditions precedent are deemed satisfied by this
Agreement.

       (b) There may be countries other than the United States in which a Party
hereto may have, as a consequence of this Agreement, rights against infringers
of the other Party's patents licensed hereunder. Each Party hereby waives any
such right it may have by reason of any third party's infringement or alleged
infringement of any such patents.

       (c) IGC hereby agrees to register or cause to be registered, to the
extent required by applicable law, and without expense to LUCENT-GRL or any of
its RELATED COMPANIES, any agreements wherein sublicenses are granted by it
under LUCENT's PATENTS. IGC hereby waives any and all claims or defenses,
arising by virtue of the absence of such registration, that might otherwise
limit or affect its obligations to LUCENT-GRL.

4.08 Dispute Resolution

       (a) If a dispute arises out of or relates to this Agreement, or the
breach, termination or validity thereof, the Parties agree to submit the dispute
to a sole mediator selected by the Parties or, at any time at the option of a
Party, to mediation by the American Arbitration Association ("AAA"). If not thus
resolved, it shall be referred to a sole arbitrator selected by the Parties
within thirty (30) days of the mediation, or in the absence of such selection,
to AAA arbitration which shall be governed by the United States Arbitration Act.

       (b) Any award made (i) shall be a bare award limited to a holding for or
against a Party and affording such remedy as is deemed equitable, just and
within the scope of the Agreement ; (ii) shall be without findings as to issues
(including but not limited to patent validity and/or infringement) or a
statement of the reasoning on which the award rests; (iii) may in appropriate
circumstances (other than patent disputes) include injunctive relief; (iv) shall
be made within four (4) months of the appointment of the arbitrator; and (v) may
be entered in any court.

       (c) The requirement for mediation and arbitration shall not be deemed a
waiver of any right of termination under this Agreement and the arbitrator is
not empowered to act or make any award other than based solely on the rights and
obligations of the Parties prior to any such termination.

       (d) The arbitrator shall be knowledgeable in the legal and technical
aspects of this Agreement and shall determine issues of arbitrability but may
not limit, expand or otherwise modify the terms of the Agreement .

       (e) The place of mediation and arbitration of this Agreement shall be New
York City.

       (f) Each Party shall bear its own expenses but those related to the
compensation and expenses of the mediator and arbitrator shall be borne equally.

       (g) A request by a Party to a court for interim measures shall not be
deemed a waiver of the obligation to mediate and arbitrate.

                                       8

<PAGE>


       (h) The arbitrator shall not have authority to award punitive or other
damages in excess of compensatory damages and each Party irrevocably waives any
claim thereto.

       (i) The Parties, their representatives, other participants and the
mediator and arbitrator shall, except as required by law, hold the existence,
content and result of mediation and arbitration in confidence.

4.09 Releases

2.01(a) and other good and valuable consideration paid by IGC to LUCENT-GRL, and

       (c) With respect to customers (purchasers and users) of a grantee, such
releases shall not extend to any patent which is directed to (i) a combination
of a product of the kind herein licensed as of the Effective Date hereof with
any other product; (ii) a method or process which is other than the inherent use
of a product of the kind herein licensed (as furnished to such customers); or
(iii) a method or process involving the use of a product of the kind herein
licensed as of the Effective Date hereof to manufacture (including associated
testing) any other product.

such claim, action or proceeding, as well as any claim, action or proceeding to

any obligation to do so. If IGC notifies LUCENT-GRL of any infringement of any
LUCENT-GRL PATENT that impairs IGC's commercial use of a LICENSE PRODUCT
(including the manufacture, sale or distribution thereof), then upon IGC's
written request, LUCENT-GRL shall, in its sole discretion, take commercially
reasonable steps to terminate further infringement through enforcement of the
applicable LUCENT-GRL PATENTS.

other stock or securities) for securities or other property deliverable upon
such reorganization, reclassification, consolidation, merger, transfer
