the Legal Protection of Computer Programs as implemented in applicable national legislation (the "Software Directive") apply to use of a Product by Vistula, its Affiliates or Sublicensees, or a
Vistula Customer, and if Vistula, any of its Affiliates or Sublicensees or a Vistula Customer wishes to obtain the information necessary to achieve interoperability of an independently created
computer program with a Product as permitted under Article 6 of the Software Directive ("Interoperability Information"), then Vistula will notify NetYantra in writing, specifying the nature of
the Interoperability Information it needs and the purpose for which it will be used. If NetYantra reasonably determines that Vistula, its Affiliate or Sublicensee, or the Vistula Customer is entitled
to such Interoperability Information under Article 6, NetYantra shall, at its option, (i) provide such information to Vistula, its Affiliate or Sublicensee, or the Vistula Customer or
(ii) authorize Vistula, its Affiliate or Sublicensee, or the Vistula Customer to reverse engineer the Product, within the limits prescribed by Article 6, solely to the extent
indispensable to obtain such Interoperability Information. If NetYantra elects clause (i), Vistula shall provide all information and assistance reasonably requested by NetYantra to enable
NetYantra to perform clause (i), and NetYantra may charge Vistula a reasonable fee, determined in NetYantra's discretion, for making available the requested Interoperability Information, unless
such a fee is prohibited under Article 6. NetYantra shall have the right to restrict the distribution of the Products in any country in the Territory upon written notice to Vistula if, in the

irrespective of whether Vistula, its Affiliates or Sublicensees, or the Vistula Customers have agreed not to publicly disclose such algorithms. 

        3.6   Infringement. If NetYantra becomes aware that a third party may be infringing or threatening to infringe the intellectual
property rights in the Products, including, patent, copyright, trademark and trade secret rights ("Products IP Rights") within the Territory, NetYantra shall provide prompt written notice thereof to
Vistula, which notice shall set forth the facts known to Vistula concerning such infringement or threatened infringement (the "Infringement Notice"). If NetYantra becomes aware that a third party may
be infringing or threatening to infringe the Product IP Rights within the Territory, whether by way of an Infringement Notice or otherwise and the exclusive nature of the appointment of Vistula as a
distributor of the Products in the Territory has not been terminated pursuant to Section 2.5, Vistula shall have the sole and exclusive right, but not the obligation, to initiate and/or pursue
legal proceedings against such third party at Vistula's sole expense. Any damage, cost, award fee, recovery, or compensation paid by any third party in connection with any legal proceeding initiated
and/or pursued at Vistula's expense (whether by way of settlement or otherwise) shall be retained by Vistula. In the event that Vistula desires to initiate or pursue, initiates or pursues any legal
proceeding against a third party to enforce or protect the Product IP Rights within the Territory, NetYantra shall fully cooperate with and supply all assistance reasonably requested by Vistula in
connection therewith. Vistula shall have sole and absolute control of the proceeding and shall bear all reasonable expenses and legal fees incurred by NetYantra in providing such cooperation and
assistance as Vistula may reasonably request. For the purposes of this Section 3.6, NetYantra shall only be "aware" of any infringement or threatened infringement of the Product IP Rights if
any member of the senior management of NetYantra including Sanjeev Menon, Vinod Sankar and Vinod Menon has actual knowledge of such infringement or threatened infringement of the Product IP Rights
unless such member of senior management, in his or her reasonable opinion does not consider such alleged infringement or infringement constitutes actual infringement or threatened infringement of the
Product IP Rights for the purposes of this Section 3.6. 

        4.    Covenants and Duties of Vistula.    

        4.1   Promotion of Products. Vistula will use reasonable efforts to promote and maximize the distribution and use of the

shall regularly consult with each other and keep each other informed during the sales, tendering and proposal process for any Vistula Customer in relation to technical and other relevant matters. 

        4.2.2 Unless
otherwise agreed in writing, all costs incurred in connection with the preparation and submission of proposals, negotiations of a contract and all other costs
incurred before the execution of a contract with a Vistula Customer shall be borne by Vistula. In no event shall either party purport to, or represent itself as having the authority to make
commitments to any customer or prospective customer on behalf of the other party, except as expressly set forth in this Agreement.

event that Vistula subcontracts these services to NetYantra and NetYantra agrees to provide these services, the scope and cost of such services shall be set forth in a statement of work agreed by the
parties hereto based on the requirements of the Vistula Customer. 

        4.5.2 Vistula

In the event that a Vistula Customer wishes to purchase support services before Vistula is equipped to deliver Tier 1 support or Vistula is unable or unwilling to provide such support, NetYantra may,
at its option, act as Vistula's subcontractor to provide such support to the Vistula Customer until such time that Vistula is able or willing to perform the support itself. In the event that NetYantra
provides such Vistula Customer with such support services, Vistula shall pay NetYantra for such services at NetYantra's then applicable rates for such services as agreed with Vistula in writing from
time to time. 

        4.6   Training. Vistula shall, at its own expense, attend the training sessions described in Section 5.4. Vistula will

training outside of such facilities, unless NetYantra agrees to forego such remuneration.

between NetYantra and its other partners and distributors, NetYantra shall communicate to Vistula information regarding all sales and sublicensing opportunities in the Territory with respect to the
Products (including the name of the prospective customer and applicable contact details) that may become known to NetYantra or any of its Affiliates. If such non-disclosure agreements or
informal understandings do not permit the communication of information regarding a sales or licensing opportunity to Vistula, NetYantra shall indicate to the potential customer that Vistula has the
exclusive right to distribute the Products in the Territory and that the customer should contact Vistula in order to obtain a license for the Products. Notwithstanding anything to the contrary in this
Agreement, with respect to an opportunity which NetYantra communicates to Vistula in accordance with this Section 4.7, if Vistula or its Affiliates or Sublicensees fail to follow up with or
contact the potential customer to whom such opportunity relates within a reasonable time (not to exceed two weeks) from receipt by Vistula of written notice of such opportunity, Vistula advises

Stock to NetYantra, pay to NetYantra the sum of $1,000,000 at any time prior to the Issue Date. Except as set forth in Section 6.2 and this Section 6.3, no payment in cash, securities or
other property shall be required by Vistula to NetYantra with respect to the Products distributed and licensed to Vistula's Customers or distributed or licensed by Vistula's Affiliates or
Subdistributors in accordance with this Agreement. 

        6.4   Delivery of Products. Vistula shall use its master copy of the Products to copy, download and/or install the Products
onto the systems hardware of Vistula Customers or to otherwise provide Vistula Customers with use of the Products. Upon request by Vistula, NetYantra shall promptly (but no later than two
(2) business days following receipt of the request) provide any necessary "key," pass code or other permission to Vistula or its Affiliates or Subdistributors to enable a Vistula Customer to
use such Products. 

        6.5   Freight; Risk of Loss. All Products ordered by Vistula from NetYantra that are required to be physically delivered to
Vistula, if any, shall be shipped by NetYantra to the Vistula facility requested by Vistula. Vistula shall pay all shipping charges in connection with the delivery of the Products to Vistula,
including all freight charges, import or export fees, insurance premiums and costs, and all taxes and duties related to any shipments. All risk of loss or damage for all Products shipped to Vistula
from NetYantra shall pass to Vistula upon delivery by NetYantra to Vistula or to Vistula's agent for delivery, whichever first occurs. 

        6.6   Payment. All payments from Vistula to NetYantra shall be made in United States Dollars. Payment shall be by wire transfer
to NetYantra's account at a commercial bank designated by NetYantra. All references in this Agreement to "$" or dollars shall mean United States dollars. 

        6.7   Pricing Benefits. Vistula will not (and it will cause its Affiliates not to and use its reasonable efforts to cause its
Subdistributors not to) enter into an End User License Agreement or sublicense agreement where the amount or terms of the payment to be received for the license or sublicense of any of the Products
are artificially reduced or suppressed in order to offer a subsidy, bonus, or an incentive, for promotion of other products or services of Vistula (or its Affiliate or Subdistributor, as the case may
be), or structured in a manner so as to provide Vistula (or its Affiliates or Subdistributors) with material non-monetary compensation or benefits (including equity) for such license or
sublicense, unless NetYantra receives a fair and equitable share of such compensation or benefits taking into account the revenue sharing principles contained in Section 6.2.3. If Vistula is
unable to cause any of its Subdistributors to comply with the requirements of this Section 6.7 as if such Subdistributor was bound by the restrictions on Vistula under this Section 6.7,
Vistula shall take all reasonable steps to terminate its agreement with such Subdistributor and shall provide a copy of any notice of such termination to NetYantra. 

        7.    Records, Right to Audit.    

        7.1   Vistula Reports. Vistula shall report to NetYantra the following information: 

        (a)   within
ten (10) days after the end of each calendar quarter, a list of all Products licensed directly by Vistula to Vistula Customers during the preceding
calendar quarter and all Products distributed by Affiliates or Subdistributors of Vistula during such calendar quarter; and 

9

 

        (b)   such
other information relating to the marketing and distribution of the Products as NetYantra shall reasonably request from time to time. 

        7.2   Business Records; Right to Audit and Copy. During the term of this Agreement and for a period of two (2) years
thereafter, Vistula shall maintain accurate records relating to the distribution of Products to Vistula Customers in the Territory and to Vistula's performance of its obligations under this Agreement
("Business Records"). The Business Records shall include, without limitation, the identity, address, contact and, if known to Vistula, hardware and operating environments of each Vistula Customer, the
type of Product and date of distribution for each Product, the dates of Product installation, a copy of each End User License Agreement and information about any maintenance and support services
purchased by the Vistula Customer. During the term of this Agreement and for a period of two (2) years thereafter, NetYantra or its designee shall have the right, at its own expense and under
reasonable conditions of prior notice, time and place, to from time to time audit and copy the Business Records. In the event any such audit discloses that Vistula has failed to pay NetYantra an
amount exceeding 5% of the NetYantra Revenue Share for a particular calendar quarter, Vistula shall pay to NetYantra all amounts shown to be due by such audit. 

        8.    Proprietary Rights and Confidentiality.    

        8.1   Ownership of Products. NetYantra and its licensors shall retain all right, title and interest in the Products throughout
the world, including without limitation, patent, copyright, trademark and trade secret rights. Except as expressly set forth in Section 3 of this Agreement, neither this Agreement, nor any
license of Products hereunder shall be construed as granting to Vistula or any other party any license or other right in or to any patent, copyright, trademark, trade secret or other proprietary right
of NetYantra or its licensors. Vistula shall not take any actions inconsistent with this Section 8.1. 

        8.2   No Decompiling or Reverse Engineering. Except as required or permitted by the Software Directive, Vistula shall not (and
shall cause its Affiliates not to and shall use it reasonable efforts to cause Subdistributors not to): 

        8.2.1 make
error corrections to or otherwise modify or adapt the software or create derivative works based upon the Products, or permit third parties to create derivative
works of the Products; 

        8.2.2 decompile,
decrypt, reverse engineer, or otherwise reduce the Products to human readable form or to gain access to trade secrets and or confidential information in the
Products; or 

        8.2.3 reproduce,
deactivate, modify or bypass the security devices, including any software or hardware key supplied with respect to use of the Products. 

        8.3    Confidential Information.    

        8.3.1 "Confidential
Information" shall mean any information, in whatever form, received by one party hereto (the "receiving party") from the other party hereto (the
"disclosing party") that is identified as being proprietary or confidential to the disclosing party or which might permit the disclosing party or its customers to obtain a competitive advantage over
those who do not have access to the information, provided, however, that Confidential Information shall not include information which (a) is or becomes a part of the public domain through no
act or omission of the receiving party, (b) was in the receiving party's lawful possession prior to the disclosure by the disclosing party and had not been obtained by the receiving party
either directly or indirectly from the disclosing party or unlawfully from any third party, (c) is lawfully disclosed to the receiving party by a third party without restriction on disclosure,
or (d) is independently developed by the receiving party. 

        8.3.2 The
receiving party hereby agrees that it will hold all Confidential Information in strict confidence and will use such Confidential Information only in accordance
with the terms of this Agreement. The receiving party shall limit the use of, and access to, the Confidential Information 

10

 

to
its employees or agents whose use of or access to the Confidential Information is necessary to carry out the receiving party's obligations under this Agreement. The receiving party shall, by all
appropriate means, prevent the unauthorized disclosure, publication, display or use of Confidential Information and shall, in any event, take at least the same precautions to protect the
confidentiality of the Confidential Information as it takes to protect its own confidential information. Notwithstanding anything to the contrary in this Section 8.3, NetYantra shall be
permitted to disclose the Tier 1 Revenue Projections to third parties solely in furtherance of its strategic business objectives with respect to the Products; provided, however, that (a) no
such disclosure shall be made to a competitor of Vistula, and (b) prior to such disclosure NetYantra obtains a written confidentiality agreement signed by such third party in which such third
party agrees to keep the Tier 1 Revenue Projections confidential and agrees not to use such Tier 1 Revenue Projections other than for the purposes of evaluating NetYantra, its Products or an
investment in NetYantra and a copy of the executed confidentiality agreement is provided to Vistula prior to such disclosure. 

        8.3.3 Vistula,
its Affiliates or Licensees shall not alter or remove any trademark or copyright, restricted rights, limited rights, proprietary rights or confidentiality
notice included in or affixed to the Products,
any Marketing Materials or any Confidential Information and shall reproduce all such notices on any copies of the Products, Marketing Materials or Confidential Information made by Vistula in
accordance with this Agreement. 

        8.4   Source Code Escrow. Promptly (but no later than thirty (30) days) following the date on which Vistula or any of
its Affiliates or Subdistributors enters into a definitive agreement with a Tier 1 carrier or an Affiliate of a Tier 1 carrier with respect to the marketing, sublicensing, support or use of the
Products, the Parties will execute a Source Code Escrow Agreement with an escrow agent named therein (the "Escrow Agent"), substantially in the form attached as  Exhibit G hereto (the "Escrow
Agreement") and NetYantra will deposit with the Escrow Agent the Products in source code form, including related
information (e.g. keys, etc.) which is reasonably required by Vistula and its Affiliates and Subdistributors to maintain and support the Products (such source code and related information, the
"Deposit"). All rights and licenses granted under or pursuant to this Agreement by NetYantra to Vistula are, for all purposes of Section 365(n) of Title 11 of the U.S. Code ("Title 11"),
licenses of rights to intellectual property as defined in Title 11. If a case is commenced by or against NetYantra under Title 11, then, unless and until this Agreement is rejected as provided in
Title 11, NetYantra (in any capacity, including debtor-in-possession) and its successors and assigns (including, without limitation, a Title 11 trustee) shall either perform
all of its support obligations provided in this Agreement or the Escrow Agent shall provide the Deposit to Vistula, as Vistula may elect in a written request to Escrow Agent in accordance with the
Escrow Agreement. If a Title 11 case is commenced by or against NetYantra, this Agreement is rejected as provided in Title 11 and Vistula elects to retain its rights hereunder as provided in Title 11,
then Escrow Agent shall provide to Vistula the Deposit in accordance with the Escrow Agreement. All rights, powers and remedies of Vistula provided herein are in addition to and not in substitution
for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including, without limitation, Title 11), if a Title 11 case is commenced by or against NetYantra. In
that event, Vistula, in addition to the rights, powers and remedies expressly provided herein, shall be entitled to exercise all other such rights and powers and resort to all other such remedies as
may now or hereafter exist at law or in equity (including Title 11). If NetYantra ceases offering or providing maintenance and support for the Products and NetYantra does not make alternative
arrangements for third party maintenance and support of the Products equivalent to support offered by NetYantra pursuant to this Agreement, NetYantra notifies Vistula that NetYantra will no longer
support any of the Products, or NetYantra failures to continue to do business in the ordinary course, on notice from Vistula in accordance with the Escrow Agreement, Escrow Agent will deliver the then
current Deposit to Vistula which will be used by Vistula for the purpose of maintaining and supporting the Products so that Vistula and the Vistula Customers can continue to use 

11

 

the
Products in accordance with the terms of the Agreement. The Escrow Agreement will be executed in accordance with this Section 8.4 and will not contain any terms or conditions contrary to or
in conflict with this Section 8.4. 

        9.    Term and Termination.    

        9.1   Term. This Agreement shall become effective upon the execution hereof by NetYantra and Vistula and shall continue for a
period of five (5) years from the Effective Date, unless earlier terminated in accordance with this Section 9. This Agreement shall automatically renew for additional two year terms
unless either party notifies the other in writing of its desire not to renew this Agreement at least ninety (90) days prior to the end of the then-current term. 

        9.2   Termination for Default. Either party may, at its option, terminate this Agreement effective upon written notice to the
other party if the other party has breached any provision of this Agreement and has failed to cure the breach within thirty (30) days of notice of the breach, unless such breach is a breach of
Section 8.2 hereof, in which case termination shall be immediate if the breach can not be cured. Notwithstanding anything to the contrary in this Agreement, this Agreement shall terminate
immediately upon the breach by Vistula of its payment obligation contained in Section 6.2.1 hereof. 

        9.3   Termination by NetYantra. NetYantra may, at its option, terminate this Agreement upon written notice to Vistula at any
time following the first anniversary of the Effective Date in the event that Vistula's Common Stock (as defined in Section 6.3) is not quoted or traded on a Stock Market or Vistula has not paid
to NetYantra the sum of $1,000,000 in each case on or before the first anniversary of the Effective Date. 

        9.4   Termination for Insolvency. Either party may terminate this Agreement upon written notice to the other party if the other
party is liquidated or dissolved, or becomes insolvent, or suffers a receiver, administrator or trustee to be appointed for it or any of its undertakings or assets, or is deemed to be unable to pay
its debts or shall cease to carry on business, or makes a general assignment for the benefit of its creditors or institutes or has instituted against it any proceeding under any law relating to
bankruptcy or insolvency or the reorganization or relief of debtors. 

        9.5   Effect of Termination. Subject to Section 9.6, upon termination of this Agreement for any reason, or upon
expiration of this Agreement without renewal, Vistula shall (and Vistula shall cause its Affiliates to and shall use its reasonable efforts to cause its Subdistributors to) cease (i) marketing,
distributing and licensing the Products, and (ii) using the Trademarks and any Marketing Materials. Immediately upon any termination of this Agreement, Vistula shall pay to NetYantra all
amounts owed to NetYantra. If Vistula is unable to cause any of its Subdistributors to comply with the requirements of this Section 9.5 as if such Subdistributor was bound by the restrictions
on Vistula under this Section 9.5, Vistula shall take all reasonable steps to terminate its agreement with such Subdistributor and shall provide a copy of any notice of such termination to
NetYantra. 

        9.6   Effect of Termination on Vistula Customers. Any termination of this Agreement shall not affect (a) the sublicenses
granted by Vistula to its Affiliates or Subdistributors solely to the extent such licenses or sublicenses are required by Vistula Affiliates or Subdistributors to support existing Maintenance
Customers or (b) the sublicenses granted by Vistula or its Affiliates or Subdistributors to Vistula Customers, as long as such Affiliates or Subdistributors or Vistula Customers are not in
breach of their respective sublicense agreement or End User License Agreement. Upon any termination of this Agreement, NetYantra shall continue to provide Tier 2 support with respect to, and Vistula
shall continue to provide Tier 1 support to, all then existing Maintenance Customers. 

        9.7   Return of Promotional Material and Confidential Information. Within ten (10) days after expiration or termination
of this Agreement, (i) Vistula shall promptly submit to NetYantra a report including the information described in Section 7.1 of this Agreement for the period from the date of the last
such report through the date of expiration or termination, (ii) Vistula and its Affiliates shall 

12

 

promptly
return to NetYantra all copies of any Confidential Information and Marketing Materials of NetYantra and NetYantra shall promptly return to Vistula all copies of any Confidential Information
of Vistula, and (iii) to the extent any such Confidential Information or Marketing Material cannot be returned by either party, such party shall erase or destroy all copies of such Confidential
Information and Marketing Materials under its control, including all copies that are fixed or running in machines controlled by it. 

        9.8   Survival of Terms. The provisions of Sections 7.2, 8, 9, 10.2, 11, 12 and 13 and any payment obligations under
Section 6 shall survive any termination of this Agreement. 

        10.    Warranties and Disclaimer.    

        10.1 Warranties. NetYantra represents and warrants to Vistula that:

        10.1.3 Exceptions. NetYantra's limited warranty set forth in Section 10.1.2 above shall not apply if breach of the
warranty has resulted from (i) accident, corruption, misuse or neglect of the Products not arising from the act or omission of NetYantra; (ii) acts or omissions by someone other than
NetYantra; (iii) combination of the Products with products, material or software not provided by NetYantra or not intended for combination with the Products; or (iv) failure by the
Vistula Customer to incorporate all updates to the Products provided by NetYantra. 

        10.2    Disclaimer of Warranties.

proceeding, (b) gives NetYantra full authority and reasonable information and assistance to defend such claim, action or proceeding, and (c) gives NetYantra sole control of the defense
and settlement of such claim, action or proceeding and all negotiations relating thereto. If a Product or any part thereof becomes, or in NetYantra's reasonable opinion is likely to become, the

the continued use of the Product or such part, to replace or modify it so that it becomes non-infringing, or to terminate the license granted herein to distribute the Product. NetYantra

understanding between the parties with respect to the subject matter hereof and supersedes all oral and written agreements and understandings relating thereto. As between the Parties, in the event of
any conflict between the terms of this Agreement and the terms of the Escrow Agreement or any sublicense agreement or end user license agreement with respect to the Products and the provisions of this
Agreement, the terms of this Agreement shall prevail.

shall be binding unless made in writing and signed by each of the parties

        13.3 Assignment. This Agreement shall be binding upon, and inure to the benefit of, the parties hereto and their respective
legal representatives, successors and permitted assigns. Vistula shall not assign any of its rights or delegate any of its duties hereunder, in whole or in part, to any third party, without the prior
written consent of NetYantra; provided, however, that Vistula may assign its rights under this Agreement to the purchaser ("Purchaser") of all or substantially all of its assets without the consent of
NetYantra, provided that (a) such Purchaser is not a competitor of NetYantra with respect to the Products and (b) such Purchaser agrees in writing to be bound by all the terms and
conditions of this Agreement (including, without limitation the obligations in Section 4.1) in place of Vistula. 

        13.4 Relationship of the Parties. The relationship between NetYantra and Vistula shall be that of independent contractors.

        13.5 No Solicitation. Each of the parties agrees that during the term of the Agreement and for one year after any expiration
or termination of this Agreement, they will not, directly or indirectly, recruit, solicit or induce (or attempt to do any of the foregoing), any specific employee or employees of the other party to
terminate such employee's employment with, or otherwise cease their relationship with, the other party without the prior written consent of such other party. 

        13.6 Severability. If any of the provisions of this Agreement are determined to be invalid, illegal, or unenforceable by a
court of competent jurisdiction, such provisions shall be severed from the Agreement, and the remaining provisions shall remain in full force and effect; provided, however, that with respect to any
material provision so severed, the parties shall negotiate in good faith to achieve the original intent of such provision.

Party shall be precluded hereby from seeking provisional remedies in the courts of any jurisdiction including, but not limited to, temporary restraining orders and preliminary injunctions to protect
its rights and interests, but such shall not be sought as a means to avoid or stay arbitration.
