AMENDED AND RESTATED EMPLOYMENT AND NONCOMPETITION AGREEMENT    
    

        This Amended and Restated Employment and Noncompetiton Agreement (this "Agreement") is entered into as of this 5th day of May, 2004, by and among Vistula
Communications Services, Inc. (formerly known as VCS, Inc.), a Delaware corporation (the "Company"), Vistula USA, Inc., a Delaware corporation and wholly owned subsidiary of the
Company (the "Employer"), and Edward DeMent (the "Employee"). 

        WHEREAS,
the Company and the Employee entered into an Employment and Noncompetition Agreement dated January 1, 2004 (the "Employment Agreement"); 

        WHEREAS,
the Company, the Employer and the Employee wish to amend and restate the Employment Agreement in its entirety to, among other things, make the Employer a party to the Employment
Agreement, increase the term of the Employment Agreement and make certain other changes to the Employment Agreement; 

        NOW,
THEREFORE, in consideration of the agreements and obligations set forth herein, and for other good and valuable consideration, the parties hereto, intending to be legally bound,
hereby agree, and agree to amend and restate the Employment Agreement in its entirety, as follows: 

        §1.    Employment.    Upon the terms and subject to the conditions described in this Agreement, the
Employer hereby employs the Employee and the Employee hereby accepts employment by the Employer. 

        §2.    Term.    Employee's employment with the Employer pursuant to this Agreement shall be for the period
(the "Initial Term") beginning on January 1, 2004 (the "Commencement Date") and ending on March 31, 2005 (the "Ending Date"); provided, however, that this Agreement may be renewed for
successive annual terms on each anniversary of the Ending Date only in writing signed by
each of the Parties. When permitted by the context, any reference in this Agreement to the "term of this Agreement" shall include the Initial Term and the period of any such extensions or renewals. 

        §3.    Services.    The Employee shall devote his full business and professional time, attention, energy,
loyalty, and skill to the Employer's business, performing such executive or administrative tasks and having such responsibilities as may be assigned to him from time to time by the Board of Directors
of the Employer (the "Employer's Board"), the Employer's Chief Executive Officer, the Board of Directors of the Company (the "Company's Board") or the Company's Chief Executive Officer with the
exception of any activities disclosed prior to the Commencement Date including, but not limited to, activities relating to Tier One Systems and TE Systems, or activities approved by the Employer's
Board or the Company's Board after the Commencement Date. 

        §4.    Compensation.    

        (a)   As
compensation for his services under this Agreement, the Employer shall pay the Employee a base salary at the monthly rate of $10,000 (the "Base Salary"), payable in
bi-weekly installments, in arrears, and in accordance with the Employer's general policies and procedures for payment of salaries to its executive personnel. The accrual of the Base Salary
shall commence on the Commencement Date and full payment of the Base Salary shall commence immediately upon the funding of the Company and all unpaid accrued base salary from the Commencement Date
will be paid within five (5) working days. Prior to the funding of the Company, the Employee shall have the right to receive payments equal to one-half of the Base Salary per month
plus thirty (30%) of gross margins realized by the Employer's operations to be defined as any traffic processed by the Sonus switching platform or other equipment, customers, or vendors managed by the
Employer's personnel. The Employee's performance shall be reviewed not less often than annually for the purpose, among others, of considering potential increases in the Base Salary, but the Employer
shall not be obligated to make any such increases. 

 

        (b)   In
addition to the compensation described in Section 4(a) above and Section 4(c) below, the Employee may earn an annual bonus (the "Performance Bonus") for
each calendar year during the term of this agreement in an amount up to three per cent (3%) of the Employer's EBITDA for the applicable period; provided, however, that a Performance Bonus shall not be
payable under this Section 4(b) if the payment of such Performance Bonus, alone or together with the payment by the Employer of similar performance bonus(es) to Mark Scully and/or Eric Pomeroy
under employment agreements between such individuals, the Employer and the Company, would cause the Employer to suffer or incur a net loss for such calendar year, as determined in accordance with
generally accepted
accounting principles ("GAAP"). "EBITDA" shall mean, as of the date of any determination and for the period specified, the aggregate of all amounts which, in accordance with GAAP, would be included as
net income (or net loss) on a consolidated statement of income of the Employer for such period, excluding (a) any extraordinary or other non-recurring gains, and (b) any
gains from the sale or disposition of assets other than in the ordinary course of business ("Consolidated Net Income") plus, to the extent deducted in the calculation of Consolidated Net Income, the
sum of (i) interest expense, (ii) deductions for income taxes, (iii) depreciation expense, and (iv) amortization expense, of the Employer, all as determined in accordance
with GAAP, on a consolidated basis for such period. 

        (c)   In
addition to the compensation described in Section 4(a) and Section 4(b) above, the Employee may earn an annual bonus (the "Bonus") for each full
calendar year during the term of this Agreement in an amount up to $95,000 per calendar year (the "Total Possible Bonus") based solely on the performance of the Employer during that calendar year. The
Bonus will be based on the Employer meeting an annual performance goal for such calandar year which shall be measured by the gross profit margin of the Employer for the calendar year calculated in
accordance with generally accepted accounting principles (the "Annual Performance Goal"). The Annual Performance Goal for a calendar year shall be determined jointly by the Company's Board and the
Employer's Board based on a review of the the Employer's annual performance goals and budgetary figures for such calendar year. If the Employer reaches at least sixty-six percent (66%) of
the Annual Performance Goal, the Bonus shall be equal to the pro-rata portion of the Total Possible Bonus equal to the percentage of the Annual Performance Goal actually reached by the
Employer (for example, if the Employer reaches eighty percent (80%) of the Annual Performance Goal, the Bonus shall be an amount equal to eighty percent (80%) of the Total Possible Bonus); provided,
however, that if the Employer does not reach at least sixty-six percent (66%) of the Annual Performance Goal, the Employee shall not be entitled to any Bonus hereunder; and provided,
further, that in no event shall the Bonus exceed the Total Possible Bonus. 

        §5.    Fringe Benefits and Perquisites.    During the term of this Agreement, the Employee shall also be
entitled to the following fringe benefits and perquisites: 

        (a)   Group
health and welfare benefits comparable to those offered generally to the Employer's executive personnel from time to time; 

        (b)   Twenty-five
days paid vacation during each year of this Agreement (prorated for any partial years during the term of this Agreement); 

        (c)   Such
other benefits and perquisites as may be offered generally to the Employer's executive personnel from time to time pursuant to such terms, conditions, and policies
as may be approved by the Employer's Board or the Company's Board. 

        §6.    Confidentiality; Noncompetition.    Providing that the Company is funded prior to June 30,
2004, the Employee shall not, directly or indirectly, at any time (whether during the term of this Agreement or thereafter), disclose any Confidential Information (defined below) to any person,
association, or other entity (other than the Affiliated Companies, as defined below), or use, or permit or assist any person, association, or other entity (other than the Affiliated Companies) to use,
any

Confidential
Information, excepting only: (i) Confidential Information which (A) is then generally available to or obtainable by the public and which did not become so available or
obtainable through the breach of any provision of this Agreement by the Employee, or (B) is obtained by the Employee on a non-confidential basis from a source other than an
Affiliated Company or any agent or other representative of an Affiliated Company and such source had the right to disclose such Confidential Information to the Employee without violating any legal,
contractual, fiduciary, or other obligation; and (ii) disclosures required by applicable law. 

        Upon
termination of his employment by the Employer (for any reason), the Employee shall immediately deliver to the Employer all documents and other materials containing any Confidential
Information which are in his possession or under his control. 

        During
the Restricted Period (defined below), the Employee shall not, directly or indirectly (whether individually or as a shareholder or other owner, partner, member, director, officer,
employee, consultant, creditor or agent of any person, association, or other entity): 

        (a)   Enter
into, engage in, or promote or assist (financially or otherwise), directly or indirectly, any business which competes with the business of any Affiliated Company
(the "Business") anywhere in the Restricted Territory, provided that the foregoing shall not preclude the Employee from owning less than 1% of the outstanding capital stock of any corporation whose
shares are publicly traded on a national securities exchange or system; 

        (b)   Solicit
or attempt to solicit business in competition with the Business from any person or entity (in any such case, a "Restricted Company"), or interfere or attempt to
interfere with any relationship of any Affiliated Company with any Restricted Company; 

        (c)   Induce
or encourage any employee, officer, director, agent, supplier, or independent contractor of any Affiliated Company to terminate its relationship with any such
Affiliated Company, or otherwise interfere or attempt to interfere in any way with any Affiliated Company's relationships with its employees, officers, directors, agents, suppliers, independent
contractors, or others; 

        (d)   Employ
or engage any person who, at any time within the one-year period immediately preceding such employment or engagement, was an employee, officer,
director, or agent of any Affiliated Company; or 

        (e)   Make
any statement (oral or written) or take any other action which would tend to disparage or diminish the reputation of any Affiliated Company. 

For
purposes of this Agreement: 

        (i)    "Affiliated
Companies" shall include the Company, the Employer and all subsidiaries or affiliates of the Company or the Employer; 

        (ii)   "Confidential
Information" shall mean all trade secrets, proprietary data, and other confidential information of any Affiliated Company, including without limitation
financial information, information relating to business operations, services, promotional practices, suppliers, employees, independent contractors, or other parties, and any information which any
Affiliated Company is obligated to treat as confidential pursuant to any course of dealing or any agreement to which it is a party or otherwise bound; 

        (iii)  the
"Restricted Period" shall mean the period beginning on the Commencement Date and ending on the first anniversary of the date (the "Termination Date") of
termination (for any reason) of Employee's employment with the Employer (whether pursuant to this Agreement or otherwise); and 

3

 

        (iv)  "Restricted
Territory" shall mean (A) at any time prior to the Termination Date, all metropolitan statistical areas ("MSAs") and all cities, towns, villages,
townships, and other similar political subdivisions, whether incorporated or unincorporated (collectively, "Cities"), in which any Affiliated Company then conducts business, owns, leases, manages, or
operates an office or other facility, and (B) on or after the Termination Date, all MSAs and Cities in which any Affiliated Company conducts business, owns, leases, manages, or operates an
office or other facility on the Termination Date. 

        The
Employee acknowledges that (1) the provisions of this section are fundamental and essential for the protection of the Employer's and the Company's legitimate business and
proprietary interests, (2) such provisions are reasonable and appropriate in all respects, and (3) in the event of any violation by the Employee of any of such provisions, the Employer
and the Company would suffer irreparable harm and its remedies at law would be inadequate. In the event of any violation or attempted violation of such
provisions by the Employee, each of the Employer and the Company shall be entitled to a temporary restraining order, temporary and permanent injunctions, specific performance, and other equitable
relief, without any showing of irreparable harm or damage or the posting of any bond, in addition to any other rights or remedies which may then be available to the Employer or the Company. 

        §7.    Company Internal Control Policy.    The Employee acknowledges that the Employee has read the
Employer's By-laws and the Company's Internal Control Policy and the Employee agrees that in the course of his employment hereunder, the Employee will comply at all times with the
Employer's By-laws and the Company's Internal Control Policy. 

        §8.    Termination.    The Employee's employment with the Employer shall terminate automatically upon the
death of the Employee and may be terminated by the Employer, without any further obligation on the part of the Employer (except as provided in clause (c), below), immediately upon notice to the
Employee under any of the following circumstances: 

        (a)   At
any time for Cause (defined below); 

        (b)   At
any time when the Employee is under a Long-Term Disability (defined below); or 

        (c)   At
any time without Cause; provided that if the Employer terminates the Employee's employment pursuant to this clause (c) and no other basis for termination
exists under this Agreement, then the Employee shall be entitled to severance payments in an aggregate amount equal to the Base Salary for a period equal to six months (any such severance payments
shall be payable periodically in the same manner as the Base Salary is payable under §4 of this Agreement). 

For
purposes of this Agreement: 

        (i)    "Cause"
shall mean: 

        (A)  any
act constituting (1) a felony under the federal laws of the United States, the laws of any state, or any other applicable law, regardless of whether a
conviction has been obtained, (2) fraud, embezzlement, misappropriation of assets, willful misfeasance, or dishonesty, or (3) other criminal conduct which in any way materially and
adversely affects the reputation, goodwill, or business position of the Employer or the Company; 

        (B)  the
failure of the Employee to perform and observe all material obligations and conditions to be performed and observed by the Employee under this Agreement, to perform
his duties in accordance with and observe the Employer's By-laws or the Company's Internal Control Policy or to perform his duties in accordance with the policies, programs, budgets,
procedures, and directions established from time to time by the Employer's Board or the Company's Board (any such failure, a "Performance 

4

 

Failure"),
and to correct such Performance Failure promptly following notice from the Employer to do so; or 

        (C)  having
corrected (or the Employer having waived the correction of) a Performance Failure, the occurrence of any subsequent Performance Failure; and 

        (ii)   "Long-Term
Disability" shall mean that, because of physical or mental incapacity, it is more likely than not that the Employee will be unable, within
180 days after such incapacity commenced, to perform the essential functions of his position with the Employer, with or without reasonable accommodation. In the event of any disagreement about
whether or when the Employee is under a Long-Term Disability, the question shall be determined: (A) by a physician selected by agreement between the Employee and the Employer if
such a physician is selected within 10 days after either of them requests the other so to agree; or, if not, (B) by two physicians, the first of whom shall be selected by the Employee
and the second of whom shall be selected by the Employer or, if the Employee fails to make a selection within 10 days after being requested to do so by the Employer, the second physician shall
be selected by the first physician; or, if the two physicians fail to agree, (C) by a third physician selected by the first two physicians. The Employee shall submit to all reasonable
examinations requested by any such physicians. 

        §9.    Capacity.    The Employee represents and warrants to the Employer that he has the capacity and
right to enter into this Agreement and perform all of his obligations under this Agreement without any restriction. 

        §10.    Remedies.    All rights and remedies of any Party under this Agreement are cumulative and in
addition to all other rights and remedies which may be available to that Party from time to time, whether under any other agreement, at law, or in equity. 

        §11.    Survival.    The termination of the Employee's employment with the Employer (for any reason) shall
not relieve any Party of any of that Party's obligations under this Agreement existing at, arising as a result of, or relating to acts or omissions occurring prior to, such termination. Without
limiting the generality of the preceding sentence, in no event shall the termination of such employment modify or affect any obligations of the Employee or rights of the Employer under §6
of this Agreement, all of which shall survive the termination of such employment. 

        §12.    Notices.    All notices and other communications under this Agreement to any Party shall be in
writing and shall be deemed given when delivered personally, telecopied (which is confirmed) to that Party at the telecopy number for that Party set forth below, mailed by certified mail (return
receipt requested) to that Party at the address for that Party (or at such other address for such Party as such Party shall have specified in notice to the other Party) or delivered to Federal

Exhibit 10.5    
    

        Effective Date: May 5, 2004 

 
 

NON-STATUTORY STOCK OPTION    
    

Granted
by 

Vistula
Communications Services, Inc. 

Under
the 

2004
Stock Incentive Plan 

        For
valuable consideration, the receipt of which is hereby acknowledged, Vistula Communications Services, Inc., a Delaware corporation (hereinafter together with its subsidiaries,
where the context permits, referred to as the "Company"), hereby grants to the Holder named in Schedule A attached hereto the following Non-Statutory Stock Option (the "Option"): 

        Section 1.    Grant of Option.    Subject to the terms and conditions hereinafter set forth, the Holder is
hereby given the right and option to purchase from the Company shares of the Company's Common Stock, $.001 par value per share (the "Common Stock"). Schedule A attached hereto and hereby
incorporated herein sets forth, with respect to this Option, (i) its expiration date, (ii) its exercise price per share, (iii) the maximum number of shares that the Holder may
purchase upon exercise hereof, and (iv) the vesting schedule. It also sets forth applicable conditions that the Company may wish to incorporate herein. This Option shall terminate in all
respects, and all rights and options to purchase
shares hereunder shall terminate, ten years from the Effective Date set forth above. The right to purchase shares hereunder shall be cumulative. 

        Section 2.    Exercise of Option.    This Option may be exercised only to the extent such Option has vested
pursuant to the terms of Section 1. Purchase of any shares hereunder shall be made by delivery to the Company of a written notice of exercise specifying the number of shares with respect to
which the Option is to be exercised and the address to which the certificate representing such shares is to be mailed, accompanied by: 

          (i)  cash,
certified or bank check or postal money order payable to the order of the Company for an amount equal to the Option price of such shares; 

         (ii)  with
the consent of the Company, shares of Common Stock of the Company which (a) either have been purchased by the Holder on the open market, or (b) have
been beneficially owned by the Holder for a period of at least six months and are not then subject to restriction under any Company plan ("mature shares"); such surrendered shares shall have a fair
market value equal to or less than the Option price of such shares and shall be accompanied by cash or a certified or bank check or postal money order in an amount equal to the difference, if any,
between the Option price of such shares and the fair market value of such shares; 

        (iii)  with
the consent of the Company, a personal recourse note issued by the Holder to the Company in a principal amount equal to such aggregate exercise price and with
such other terms, including interest rate and maturity, as the Company may determine in its discretion, provided that the interest rate borne by such note shall not be less than the lowest applicable
federal rate, as defined in Section 1274(d) of the Internal Revenue Code of 1986, as amended; 

        (iv)  with
the consent of the Company, if the class of Common Stock is registered under the Securities Exchange Act of 1934 (the "Exchange Act") at that time, subject to
rules as may be established by the Board of Directors of the Company (the "Board"), irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to
the Company for the purchase price; 

         (v)  with
the consent of the Company, instructions to reduce the number of shares otherwise issuable to the Holder upon the exercise of the Option by a number of shares of
Common Stock 

 

having
a fair market equal to the aggregate exercise price; provided, however, that the Holder otherwise owns an equal number of mature shares; or 

        (vi)  with
the consent of the Company, a combination of (i), (ii), (iii), (iv) and/or (v). 

        For
the purpose of the foregoing, the fair market value of the shares of Common Stock which may be delivered to the Company upon exercise of the Option shall be determined in accordance
with procedures adopted by Board. 

        Section 3.    Conditions and Limitations.    As a condition precedent to any exercise of this Option, the
Holder (or if any other individual or individuals are exercising this Option, such individual or individuals) shall deliver to the Company an investment letter in form and substance satisfactory to
the Company and its counsel which shall contain, among other things, a statement in writing to the following effects (to the extent then applicable): (i) that the Option is then being exercised
for the account of the Holder and only with a view to investment in, and not for, in connection with or with a view to the disposition of, the shares with respect to which the Option is then being
exercised; (ii) that the Holder acknowledges that the rights of first refusal and repurchase set forth in Section 9 hereof apply to such shares; (iii) that the Holder has been
advised that Rule 144 of the Securities and Exchange Commission (the "Commission"), which permits the resale, subject to various terms and conditions, of small amounts of "restricted
securities" (as therein defined) after they have been held for one year, does not now apply to the Company because the Company is not now required to file, and does not file, current reports under the
Exchange Act, nor is there publicly available information concerning the Company substantially equivalent to that which would be available if the Company were required to file such reports;
(iv) that the Holder understands that there is no assurance that the Company will ever become a reporting company under the Exchange Act and that the Company has no obligation to the Holder to
do so; (v) that the Holder and Holder's representatives have fully investigated the Company and the business and financial conditions concerning it and have knowledge of the Company's then
current corporate activities and financial condition; and (vi) that the Holder believes that the nature and amount of the shares being purchased are consistent with Holder's investment
objectives, abilities and resources. The restrictions imposed by this Section and any investment representation made pursuant to this Section shall be inoperative upon the registration with the
Commission of the stock subject to this Option or acquired through the exercise of this Option under the Securities Act of 1933, as amended (the "Securities Act"). 

        The
Holder also agrees for a period of up to 180 days from the effective date of any registration of securities of the Company under the Securities Act, upon request of the
Company or the underwriters managing any underwritten offering of the Company's securities, not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any
shares issued pursuant to the exercise of this Option, without the prior written consent of the Company and such underwriters. 

        Section 4.    Delivery of Shares.    Within a reasonable time following the receipt by the Company of the
written notice and payment of the Option price for the shares to be purchased thereunder and, if applicable, the investment letter referred to in Section 3, the Company will deliver or cause to
be delivered to the Holder (or if any other individual or individuals are exercising this Option, to such individual or individuals) at the address specified pursuant to Section 2 hereof a
certificate or certificates for the number of shares with respect to which the Option is then being exercised, registered in the name of the Holder (or the name or names of the individual or
individuals exercising the Option, either alone or jointly with another person or persons with rights of survivorship, as the individual or individuals exercising the Option shall prescribe in writing
to the Company); provided, however, that such delivery shall be deemed effected for all purposes when a stock transfer agent or the Company shall have deposited such certificate or certificates in the
United States mail, addressed to the Holder (or such individual or individuals) at the address so specified; and provided further that 

2

 

if
any law, regulation or order of the Commission or other body having jurisdiction in the premises shall require the Company or the Holder (or the individual or individuals exercising this Option) to
take any action in connection with the sale of the shares then being purchased, then, subject to the other provisions of this paragraph, the date on which such sale shall be deemed to have occurred
and the date for the delivery of the certificates for such shares shall be extended for the period necessary to take and complete such action, it being understood that the Company shall have no
obligation to take and complete any such action. 

        Section 5.    Adjustments Upon Changes in Capitalization.    The existence of this Option shall not affect in
any way the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company's capital structure or its
business, or any merger or consolidation of the Company, or any issue of bonds, debentures, preferred or prior preference stock ahead of or affecting the Common Stock or the rights thereof, or the
dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise. 

        If
the Company shall effect a subdivision or consolidation of shares or other capital readjustment, the payment of a stock dividend, or other increase or reduction of the number of
shares of the Common Stock outstanding, without receiving compensation therefor in money, services or property, then the number, class, and per share price of shares of stock subject to this Option
shall be appropriately adjusted in such a manner as to entitle the Holder to receive upon exercise of this Option, for the same aggregate cash consideration, the same total number and class of shares
that the owner of an equal number of outstanding shares of Common Stock would own as a result of the event requiring the adjustment. 

        Except
as hereinbefore expressly provided, the issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, for cash or property, or
for labor or services, either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares
or other securities,
shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock then subject to this Option. 

        Section 6.    Effect of Certain Transactions.    If the Company is a party to a merger or reorganization with
one or more other corporations, whether or not the Company is the surviving or resulting corporation, or if the Company consolidates with or into one or more other corporations, or if the Company is
liquidated or sells or otherwise disposes of substantially all of its assets to another corporation (each hereinafter referred to as a "Transaction"), in any case while this Option remains
outstanding: 

          (i)  after
the effective date of such Transaction this Option shall remain outstanding and shall be exercisable in shares of Common Stock or, if applicable, shares of such
stock or other securities, cash or property as the holders of shares of Common Stock received pursuant to the terms of such Transaction; 

         (ii)  the
Board may accelerate the time for exercise of this Option, so that from and after a date prior to the effective date of such Transaction this Option shall be
exercisable in full; 

        (iii)  this
Option may be cancelled by the Board as of the effective date of the Transaction, provided that (a) notice of such cancellation shall have been given to
the Holder and (b) the Holder shall have the right to exercise this Option to the extent the same is then exercisable or, if the Board shall have accelerated the time for exercise of this
Option, in full during the thirty-day period preceding the effective date of the Transaction; or 

        (iv)  in
the event of a Transaction under the terms of which holders of Common Stock of the Company receive upon consummation thereof a cash payment for each share
surrendered (the 

3

 

"Transaction
Price"), the Holder shall be provided a cash payment equal to the difference between (a) the Transaction Price times the number of shares of Common Stock subject to this Option (to
the extent the exercise price is not in excess of the Transaction Price) and (b) the aggregate exercise price of all such shares of Common Stock subject to this Option, in exchange for the
termination of this Option. 

        Section 7.    Rights of Holder.    No person shall, by virtue of the granting of this Option to the Holder, be
deemed to be a holder of any shares purchasable under this Option or to be entitled to the rights or privileges of a holder of such shares unless and until this Option has been exercised with respect
to such shares and they have been issued pursuant to that exercise of this Option. 

        The
granting of this Option shall not impose upon the Company any obligations to continue the Holder's services to the Company; and the right of the Company to terminate the services of
the Holder shall not be diminished or affected by reason of the fact that this Option has been granted to the Holder. 

        At
all times while any portion of this Option is outstanding, the Company shall: reserve and keep available, out of shares of its authorized and unissued stock or reacquired shares, a
sufficient number of shares of its Common Stock to satisfy the requirements of this Option; comply with the terms of this Option promptly upon exercise of the Option rights; and pay all fees or
expenses necessarily incurred by the Company in connection with the issuance and delivery of shares pursuant to the exercise of this Option. 

        Section 8.    Transfer and Termination.    This Option is not transferable by the Holder otherwise than by will
or the laws of descent and distribution. Notwithstanding the foregoing, the Holder may transfer or assign that portion of this Option which entitles the Holder to purchase 200,000 shares of Common
Stock to MRS Partners LLC ("MRS Partners"); provided, that, this Option has, at the time of such transfer or assignment, vested with respect to at least 200,000 shares of Common Stock. In the event of
the transfer or assignment of a portion of this Option to MRS Partners as provided herein, the Company shall issue a new Option to MRS Partners with respect to such 200,000 shares of Common Stock
which shall be fully vested and this Option shall be modified so as to apply only to the remaining shares of Common Stock subject to this Option. The Company shall issue a new form of this Option
reflecting such modifications to the Holder. Any transferee or assignee of this Option (or a portion thereof) shall be subject to all of the terms and conditions applicable to this Option (and the
shares issuable upon exercise of this Option) immediately prior to the transfer or assignment and shall be subject to any conditions prescribed by the Board or the Committee with respect to this
Option (or the shares issuable upon exercise of this Option). In particular, and without limiting the generality of the foregoing, the termination of employment, retirement or death of the Holder
shall continue to determine the term and time of exercise of the Option (and any portion thereof transferred or assigned to MRS Partners). 

        This
Option is exercisable, during the Holder's lifetime, only by the Holder and, with respect to any portion of the Option which is transferred or assigned to MRS Partners, MRS
Partners, and only while the Holder is providing services to the Company, except that in the event that the Holder's services to the Company terminate for any reason other than death, disability or
termination for cause, the Holder shall have the right to exercise this Option (and MRS Partners shall have the right to exercise that portion of this Option transferred or assigned to MRS Partners)
within a period of sixty days after said termination (but not later than the expiration date of this Option) with respect to the shares which were purchasable by the Holder or MRS Partners, as the
case may be, by exercise of this Option (and that portion of this Option transferred or assigned to MRS Partners) at the time of such termination of services. 

        In
the event of the Long-Term Disability, as defined in Section 8 of the Amended and Restated Employment and Noncompetition Agreement dated May 5, 2004 (the
"Employment Agreement"), by 

4

 

and
among the Holder, the Company and Vistula USA, Inc., a wholly owned subsidiary of the Company (the "Employer") or the death of the Holder prior to termination of the Holder's services to
the Company or the Employer and before the date of expiration of this Option, the Holder, or in the event of death, his executors, administrators, heirs or legatees, as the case may be, shall have the
right to exercise this Option (and MRS Partners shall have the right to exercise any portion of this Option transferred or assigned to MRS Partners) at any time within one year after said disability
or death (but not after the termination date of this Option) with respect to the shares which were purchasable by the Holder and MRS Partners at the date of the Holder's disability or death. 

        If
the Holder's services to the Company or the Employer are terminated by the Company or the Employer for Cause, as defined in Section 8 of the Employment Agreement, this Option
(and any portion of this Option transferred or assigned to MRS Partners) shall immediately terminate and shall thereafter be of no further force and effect. The Board shall have sole authority and
discretion to determine whether the Holder's services have been terminated for Cause. 

        Section 9.    Right of First Refusal.    Prior to the effective date of a registration statement under the
Securities Act covering any shares of the Company's Common Stock and until such time as the Company shall have affected a public offering of its Common Stock, in the event that, at any time when the
Holder (which term for purposes of this Section 9 shall mean the Holder and his executors, administrators and any other person to whom this Option may be transferred by will or the laws of
descent and distribution and, if a portion of this Option is transferred or assigned to MRS Partners, MRS Partners) is permitted to do so, the Holder desires to sell, assign or otherwise transfer any
of the shares issued upon the exercise of this Option, the Holder shall first offer such shares to the Company by giving written notice of the Holder's desire so to sell, assign or transfer such
shares. The notice shall state the number of shares offered, the name of the person or persons to whom it is proposed to sell, assign or transfer such shares and the price at which such shares are
intended to be sold, assigned or transferred. Such notice shall constitute an offer to the Company for the Company to purchase the number of shares set forth in the notice at a price per share equal
to the price stated therein. The Company may accept the offer as to all, but not less than all, such shares by notifying the Holder in writing within 30 days after receipt of such notice of its
acceptance of the offer. If the offer is accepted, the Company shall have 60 days within which to purchase the offered shares at a price per share as aforesaid. If within the applicable time
periods the Holder does not receive notice of the Company's intention to purchase the offered shares, or if payment in full of the purchase price is not made by the Company, the offer shall be deemed
to have been rejected and the Holder may transfer title to such shares within 90 days from the date of the Holder's written notice to the Company of the Holder's intention to sell, but such
transfer shall be made only to the proposed transferee and at the proposed price as stated in such notice and after compliance with any other provisions of this Option applicable to the transfer of
such shares. Shares that are so transferred to such transferee shall remain subject to the rights of the Company set forth in this Section 9. No sale, assignment, pledge or transfer of any of
the shares covered by this Option shall be effective or given effect on the books of the Company unless all of the applicable provisions of this Section 9 have been duly complied with, and the
Company may inscribe on the face of any certificate representing any of such shares a legend referring to the provisions of this Section 9. If any transfer of shares is made or attempted in
violation of the foregoing restrictions, or if shares are not offered to the Company as required hereby, the Company shall have the right to purchase such shares from the owner thereof or his
transferee at any time before or after the transfer, as herein provided. In addition to any other legal or equitable remedies which it may have, the Company may enforce its rights by actions for
specific performance (to the extent permitted by law) and may refuse to recognize any transferee as one of its stockholders for any purpose, including, without limitation, for purposes of dividend and
voting rights, until all applicable provisions hereof have been complied with.

        For
purposes of the Right of First Refusal pursuant to this Section 9, the term "shares" shall mean any and all new, substituted or additional securities or other property issued
to the Holder, by reason of his ownership of Common Stock pursuant to the exercise of this Option, in connection with any stock dividend, liquidating dividend, stock split or other change in the
character or amount of any of the outstanding securities of the Company, or any consolidation, merger or sale of all or substantially all of the assets of the Company. 

        Any
certificate representing shares of stock subject to the provisions of this Section 9 may have endorsed thereon one or more legends, substantially as follows: 

          (i)  "Any
disposition of any interest in the securities represented by this certificate is subject to restrictions, and the securities represented by this certificate are
subject to certain options, contained in a certain agreement between the record holder hereof and the Company, a copy of which will be mailed to any holder of this certificate without charge upon
receipt by the Company of a written request therefor." 

         (ii)  "The
shares of stock represented by this certificate have not been registered under the Securities Act of 1933 or under the securities laws of any state and may not be
pledged, hypothecated, sold or otherwise transferred except upon such registration or upon receipt by the Company of an opinion of counsel satisfactory to the Company, in form and substance
satisfactory to the Company, that such registration is not required." 

        The
restrictions imposed by this Section 9 shall terminate in all respects upon the effective date of a registration statement under the Securities Act covering the Company's
Common Stock. 

        Section 10.    Notice.    Any notice to be given to the Company hereunder shall be deemed sufficient if
addressed to the Company and delivered to the Company, 40 Portman Square, 4th Floor, London W1H 6LT, attention of Chief Executive Officer, or such other address as the Company may
hereafter designate with a copy to Paul Bork, Esq., Foley Hoag LLP, 155 Seaport Boulevard, Boston, MA 02210. 

        Any
notice to be given to the Holder hereunder shall be deemed sufficient if addressed to and delivered in person to the Holder at his address furnished to the Company or when deposited
in the mail, postage prepaid, addressed to the Holder at such address. 

        Section 11.    Withholding of Taxes.    The Holder hereby agrees that the Company may withhold from amounts due
to the Holder from the Company the appropriate amount of federal, state and local withholding taxes attributable to the Holder's exercise of this Option. 

        At
the Holder's election, the amount required to be withheld may be satisfied, in whole or in part, by (i) authorizing the Company to withhold from shares of Common Stock to be
issued pursuant to the exercise of this Option a number of shares with an aggregate fair market value that would satisfy the minimum withholding amount due with respect to such exercise, or
(ii) transferring to the Company a sufficient number of mature shares of Common Stock with an aggregate fair market value that would satisfy the minimum withholding amount due. 

        The
Holder further agrees that, if the Company does not withhold an amount due to the Holder from the Company sufficient to satisfy the Company's withholding obligation, the Holder will
reimburse the Company on demand, in cash, for the amount underwithheld. 

        Section 12.    Government and Other Regulations; Governing Law.    This Option is subject to all laws,
regulations and orders of any governmental authority which may be applicable thereto and, notwithstanding any of the provisions hereof, the Holder agrees that he will not exercise the Option granted
hereby nor will the Company be obligated to issue any shares of stock hereunder if the exercise thereof or the issuance of such shares, as the case may be, would constitute a violation by the Holder
or the Company of any such law, regulation or order or any provision thereof. Without limiting the 

6

 

generality
of the foregoing, the Company shall not be obligated to issue any such shares if in the Company's sole judgment to do so would cause the Company or such issue not to be in compliance with
the requirements of Rule 504 promulgated under the Securities Act. The Company shall not be obligated to take any affirmative action in order to cause the exercise of this Option or the
issuance of shares pursuant hereto to comply with any such law, regulation, order or provision. 

        This
Option is and shall be subject in every respect to the provisions of the Company's 2004 Stock Incentive Plan, as amended from time to time, which is incorporated herein by reference
and made a part hereof. The Holder hereby accepts this Option subject to all the terms and provisions of the Plan and agrees that (a) in the event of any conflict between the terms hereof and
those of the Plan, the latter shall prevail, and (b) all decisions under and interpretations of the Plan by the Committee or the Board shall be final, binding and conclusive upon the Holder and
his heirs and legal representatives. 

        This
Option shall be governed by and construed in accordance with the laws of the State of Delaware. 

        Section 13.    Effective Date.    This Option shall be effective on the Effective Date set forth on page 1
hereof.
