##### W  I T N E S S E T H :

WHEREAS, the Executive currently serves the Company as its Chief Executive Officer and as the Chairman of its Board;

WHEREAS, the Company wishes that the Executive continue to serve as its Chief Executive Officer and as the Chairman of its
Board, and the Executive is willing to so serve;

WHEREAS,
the Company and the Executive (individually a Party and together the
Parties) desire to enter into an agreement embodying the
terms of such continued employment;

WHEREAS,
the current Parties are parties to an Employment Agreement, dated August 4, 1997
and subsequently amended by an Amendment dated April 6, 1998 (as so amended, the
1997 Employment Agreement);

NOW,
THEREFORE, in consideration of the premises and mutual covenants contained
herein and for other good and valuable consideration, the receipt of which is
mutually acknowledged, the Parties agree as follows:

1.               Definitions.       Capitalized terms not otherwise defined herein shall have the meanings set forth in Exhibit A.

2.        
Term.       The Company hereby employs the Executive under this
Agreement, and the Executive hereby accepts such employment, for the Term. The
Term shall commence as of August 4, 2000 (the Effective Date) and
shall end on August 4, 2003; provided, however, that the Term shall thereafter
be automatically and indefinitely extended for additional one year periods
unless either Party shall give the other written notice at least three months
prior to the then-scheduled date of expiration of the Term that such Party is
electing not to so extend the Term. Notwithstanding the foregoing, the Term may
be earlier terminated in strict accordance with the provisions of Section 9.

3.          Positions, Duties and Location.
                           
(a)          During the Term, the Executive shall serve as the Chief Executive Officer of the Company and as the
Chairman of the Board; shall (subject to the provisions of the Amended and Restated Bylaws of the Company) have all authorities and
responsibilities customarily exercised by an individual serving in those positions in a corporation of the size and nature of the
Company; shall be assigned no duties that are materially inconsistent with, or that materially impair his ability to discharge, the
foregoing authorities and responsibilities; and shall report solely and directly to the Board.

(b)          During the Term, the Executive shall devote substantially all of his business time and efforts to the
affairs of the Company and its Affiliates, provided that nothing herein shall preclude him from: (i) serving on the boards of a
reasonable number of business entities, trade associations and charitable organizations, (ii) engaging in charitable, political and
professional activities and community affairs, (iii) accepting and fulfilling a reasonable number of speaking engagements, and (iv)
managing his personal investments and affairs; provided that such activities do not in the aggregate materially interfere with the
proper performance of his duties and responsibilities hereunder. Notwithstanding the foregoing, Executive shall only serve on
for-profit corporate boards of directors if specifically approved in advance by the Board (which approval shall not be unreasonably
withheld), provided, however, nothing shall preclude Executive from serving on the boards of any for-profit enterprises on which he
is currently serving as listed on Exhibit B.

(c)         
During the Term, the Executive's principal office, and principal place of employment, shall be at the
Company's headquarters in the Washington, D.C. Metropolitan Area. The Parties contemplate that, while a substantial portion of the
Company's business will be conducted in the Washington, D.C. - Baltimore Metropolitan Area, the Executive will maintain a permanent
residence in the New York Metropolitan Area and the Executive will pay for all costs of commuting between Washington, D.C. and New
York, subject to such reimbursement as may be provided pursuant to Section 8(b)(i).  For avoidance of doubt, it is acknowledged that
the Executive will be required to travel, both domestically and internationally, in connection with performing his duties.

4.         
Base Salary.        Commencing as of the Effective Date, the Executive
shall receive an annualized Base Salary of $500,000 in respect of his services
during the Term, payable in accordance with the regular payroll practices
applicable to senior executives of the Company but no less frequently than
bi-weekly. The Base Salary shall be reviewed no less frequently than annually
during the Term for increase in the sole discretion of the Board (or its
Compensation Committee). The Base Salary shall not be decreased at any time, or
for any purpose, during the Term (including, without limitation, for the purpose
of determining benefits due under Section 9) without the prior written
consent of the Executive.

5.
         Annual Incentive Awards.       The Executive shall be entitled to an
annual incentive award in respect of each fiscal year of the Company any portion
of which falls within the Term. With respect to each such year, the
Executives target annual incentive award opportunity shall be no less than
80% of his Base Salary for such year (with a maximum of 100% of Base Salary).
The annual bonus criteria shall be as determined by the Board (or its
Compensation Committee) in consultation with the Executive. At the end of each
such year the Board (or its Compensation Committee) shall determine the
Executives award based on his performance for such year. The bonus for the
year 2000 shall be determined as follows: (i) for the period prior to the
Effective Date, a Pro-Rata Annual Incentive Award pursuant to the 1997
Employment Agreement and (ii) for the period after the Effective Date, a
Pro-Rata Annual Incentive Award pursuant to this Agreement.

6.
         Stock Options.      
                            (a)          Effective as of the Effective Date, the Executive
shall be granted a ten-year Stock Option, in
substantially the form attached hereto as Exhibit C, covering 858,754 Shares at an exercise price of $11.00 per share, which the
Parties agree will represent the fair value of a Share as of such date.

(b)         
Effective as of the Effective Date, the Stock Option granted to the Executive pursuant to Section 2(d) of
the 1997 Employment Agreement shall be deemed amended to provide for transferability to "Permitted Transferees" to the maximum extent
permitted as of the Effective Date under Section 14(a) of the Company's 1997 Stock Incentive Plan.

7.          
Other Long-Term Incentives.      During the Term, the Executive shall
be eligible for additional and other long-term incentives (including, without
limitation, additional Stock Option grants) at a level, and on terms and
conditions, that are commensurate with his positions and responsibilities at the
Company and appropriate in light of corresponding awards to other senior
executives of the Company.

8.         Other Benefits.

(a)          Employee Benefits.     During the Term, the Executive shall be entitled to participate in all employee benefit
plans, programs and arrangements made available generally to senior executives of the Company (or its Subsidiaries), including,
without limitation, pension, profit-sharing, income deferral, savings and other retirement plans or programs, medical, dental,
vision, prescription drug, hospitalization, short-term and long-term disability and life insurance plans or programs, accidental
death and dismemberment protection, travel accident insurance, and any other employee benefit plans, programs or arrangements that
may from time to time be made available, including any plans, programs or arrangements that supplement the above-listed types of
plans, programs or arrangements, whether funded or unfunded; provided, however, that nothing in this Agreement shall be construed to
require the Company (or its Subsidiaries) to establish or maintain any such plans, programs or arrangements except as expressly set
forth herein.  The Executive shall be entitled to participate in all such plans, programs and arrangements at a level, and on terms
and conditions, that are commensurate with his positions and responsibilities at the Company and that are no less favorable to him
than to other senior executives of the Company (or its Subsidiaries).  The Executive shall be entitled to post-retirement welfare
benefits on no less favorable a basis than that applying to other senior executives of the Company (or its Subsidiaries).

(b)          Fringe Benefits, Perquisites and Vacations.

(i)           The Executive shall be promptly reimbursed by the Company up to a total of $100,000 per annum to
cover the cost during the Term of (A) a Company-provided  automobile,  including
reimbursement  of  expenses  of  operation,   maintenance  and  insurance,   (B)
car-service from his New York residence to the airport,  (C) an apartment in the
Washington,  D.C.  area and upgrade of  existing  furnishings,  (D)  expenses of

participate  in  all  fringe  benefits  and  perquisites   available  to  senior
executives  of the Company  (or its  Subsidiaries)  at levels,  and on terms and
conditions, that are commensurate with his positions and responsibilities at the
Company  and no less  favorable  to him than  those  applying  to  other  senior
executives of the Company (or its Subsidiaries) and shall be entitled to receive
such  additional  fringe  benefits  and  perquisites  as the Company may, in its
discretion, from time-to-time provide.

(iii)         
During the Term, the Executive shall be entitled to five weeks' paid vacation per calendar year.
Vacation days shall be taken in accordance with the policies that are applicable
to senior  executives of the Company,  generally.  Unused vacation days shall be
subject to the Companys policy on carryover.

c)          Reimbursement of Business and Other Expenses.           The Executive shall be promptly reimbursed for all expenses
reasonably incurred by him in connection with his duties and responsibilities under this Agreement, subject to documentation in
accordance with reasonable policies previously communicated to him in writing.  He shall also be promptly reimbursed for any and all
expenses (including, without limitation, attorneys' fees and other charges of counsel) incurred by him in connection with the
negotiation and documentation of these employment arrangements.

9.
         Termination of Employment.      
                           
(a)          Termination Due to Death.         In the event that the Executive's employment hereunder is terminated due to his
death, his estate or his beneficiaries (as the case may be) shall be entitled to:

(i)           payment of severance in an amount equal to his annualized Base Salary payable biweekly for a
period of one year following his date of death;

(ii)           prompt payment of a Pro-Rata Annual Incentive Award for the year in which his death occurs;

(iii)          for Stock Options granted prior to the Effective Date, vesting, as of the date of death, of any

year in which death occurs, with continued exercisability of vested Stock
Options for a period of two years following the date of death; and

(iv)           for Stock Options granted as of or following the Effective Date, full vesting and exercisability,
as of the date of death,
for all outstanding Stock Options, each such Stock Option to remain exercisable
for the lesser of (A) five years following the date of death or (B) the
remaining stated term of the Stock Option.

(b)          Termination Due to Disability.         In the event that the Executive's employment hereunder is terminated due to
Disability, he shall be entitled to:

(i)            disability benefits in accordance with the long-term disability program(s) in effect as of the
Termination Date for senior executives of the Company;

(ii)            Base Salary through the end of the month in which the long-term disability benefits commence;

(iii)            prompt payment of a Pro-Rata Annual Incentive Award for the year in which his employment
terminates;

(iv)            for Stock Options granted prior to the Effective Date, vesting, as of the date of termination, of
any tranche not vested in the year in which termination occurs with continued exercisability of vested Stock Options for a period of
two years following the date of termination;

(v)           for Stock Options granted as of or following the Effective Date, full vesting and exercisability,

(vi)           continued participation, through the later of the then scheduled expiration of the Term and the
second  anniversary  of the  Termination  Date,  in all welfare  benefit  plans,
programs and arrangements (including,  without limitation,  all medical, dental,
vision,  hospitalization  and life insurance coverages and benefits) in which he
or his family members were  participating  on such date, on terms and conditions
that are no less favorable to him and his family members than those that applied
on such date and with COBRA benefits commencing thereafter, provided that
the  Companys  obligation  under this Section 9(b)(vi) shall be reduced to
the  extent  that   equivalent   coverages   and  benefits   (determined   on  a
coverage-by-coverage and benefit-by-benefit basis) are provided under the plans,
programs or arrangements of a subsequent  employer and  provided  further
that,  to the  extent  (if any)  that  the  Companys  plans do not  permit
continuation of coverages and benefits after the  Termination  Date, the Company
shall provide the Executive,  quarterly in advance, an amount that is sufficient
(after  taxes) to purchase such  coverages and benefits on an individual  basis.

No termination of the Executive's employment for Disability shall be effective unless the Party terminating
his employment first gives 15 days' written notice of such termination to the other Party.

(c)          Termination by the Company for Cause.

(i)           No termination of the Executive's employment by the Company for Cause shall be effective as a
termination for Cause
unless the provisions of this Section 9(c)(i) shall first have been complied
with. The Executive shall be given written notice by the Board of its intention
to terminate him for Cause, such notice to state in detail the particular
circumstances that constitute the grounds on which the proposed termination for
Cause is based and to be given no later than 180 days after the Board first
learns of such circumstances. The Executive shall have 10 days after receiving
such notice in which to cure such grounds, to the extent that cure is possible.
If he fails to cure such grounds and the Board gives him written notice
confirming that, in the judgment of a majority of its members, Cause for
terminating his employment on the basis set forth in the original notice still
exists, his employment with the Company may thereupon be terminated for Cause,
subject to de novo review, at his election, through arbitration in
accordance with Section 15.

(ii)           In the event that the Executive's employment hereunder is terminated by the Company for Cause in
accordance with
Section 9(c)(i), (A) he shall be entitled to the continued right to
exercise any Stock Option, to the extent that such Stock Option is vested or
exercisable as of the Termination Date, for the lesser of 90 days following the
Termination Date and the remainder of its maximum stated term, at which time
such Stock Option shall terminate and be forfeited and (B) any Stock Option, to
the extent that such Stock Option is neither vested nor exercisable as of the
Termination Date, shall immediately terminate and be forfeited.

(d)          Termination Without Cause.         In the event that the Executive's employment hereunder is terminated by the
Company, other than for Disability in accordance with Section 9(b) or for Cause in accordance with Section 9(c) or by expiration of
the Term pursuant to notice of non-extension in accordance with Section 2, he shall be entitled to:

(i)          payment of his Base Salary at the annualized rate in effect on the Termination Date, in biweekly
payments for a period of 24 months following such termination or until the end of the Term, whichever is longer;

(ii)           prompt payment of a Pro-Rata Annual Incentive Award for the year in which his employment
terminates;

(iii)           for Stock Options granted prior to the Effective Date, vesting, as of the date of termination, of
any tranche not vested in the year in which termination occurs with continued exercisability of vested Stock Options for a period of
two years following the date of termination;

(iv)          for Stock Options granted as of or following the Effective Date, full vesting and exercisability,
as of the date of
termination, for all outstanding Stock Options, each such Stock Option to remain
exercisable for the lesser of (A) five years following the date of termination
or (B) the remaining stated term of the Stock Option; and

(v)           continued participation, through the Salary Continuation Period, in all welfare benefit plans,
programs and arrangements
(including, without limitation, all medical, dental, vision, hospitalization and
life insurance coverages and benefits) in which he or his family members were
participating on such date, on terms and conditions that are no less favorable
to him and his family members than those that applied on such date and with
COBRA benefits commencing thereafter, provided that the Companys
obligation under this Section 9(d)(iv) shall be reduced to the extent that
equivalent coverages and benefits (determined on a coverage-by-coverage and
benefit-by-benefit basis) are provided under the plans, programs or arrangements
of a subsequent employer and provided further that, to the extent (if
any) that the Companys plans do not permit continuation of coverages and
benefits after the Termination Date, the Company shall provide the Executive,
quarterly in advance, an amount that is sufficient (after taxes) to purchase
such coverages and benefits on an individual basis.

(e)          Constructive Termination Without Cause.          In the event that a Constructive  Termination Without Cause
occurs, the Executive shall have the same entitlements as provided under Section 9(d) in the case of a termination by the Company
without Cause.

(f)          Voluntary Termination.          In the event that the Executive terminates his employment hereunder prior to the

then-scheduled expiration of the Term on his own initiative (other than by death, for Disability or by a Constructive Termination
Without Cause), the provisions of Section 9(c)(ii)(A) & (B) shall apply as if his employment had been terminated by the Company for
Cause.  A voluntary termination under this Section 9(f) shall be effective 90 days after the Executive gives written notice of
termination to the Company (unless the Company elects, on notice to the Executive, to make the termination effective earlier) and
shall not be deemed a breach of this Agreement.

(g)          Expiration of the Term.          In the event that the Executive's employment hereunder terminates by expiration of
the Term pursuant to notice of non-extension in accordance with Section 2, (i) the Executive shall be entitled to prompt payment of a
Pro-Rata Annual Incentive Award for the year in which his employment terminates and (ii) any Stock Option that is, or becomes,
exercisable as of the Termination Date shall remain exercisable and nonforfeitable for the lesser of (A) five years or (B) the
remaining stated term of the Stock Option.

(h)          Miscellaneous.

(i)           On any termination of the Executive's employment hereunder, he shall be entitled to (A) prompt
payment of any unpaid Base
Salary through the Termination Date, (B) prompt payment of the balance of any
annual, long-term, or other incentive award earned, but not yet paid (subject to
deferral of payments to the extent that the Executive has irrevocably elected
such deferral), (C) prompt payment of any amounts due under Section 8, (D)
a prompt lump-sum payment for accrued but unused vacation days, (E) prompt
provision of other benefits in accordance with applicable plans, programs and
arrangements of the Company and its Affiliates (including, without limitation,
Sections 7, 10 and 11) and (F) have all payments owed to him in connection with
the termination made by wire transfer of same day funds to the extent reasonably
requested by him.

(ii)           Upon the Executive's election by written notice given to the Company within ten (10) business days
after the Termination Date,
the Company shall pay the aggregate Fair Value of any Stock Option that is then
vested or exercisable as of the Termination Date (the Cash Out
Amount) to the Executive over time in the event no shares of Series A
through Series E Convertible Preferred Stock of the Company are issued and
outstanding and a Qualified Public Offering (as such term is defined in the 1997
Stock Incentive Plan) has not occurred, (x) if the Company has sufficient funds
on hand and if the Indenture permits, in a lump sum payable as soon as
practicable and (y) if the Company does not have sufficient funds on hand or if
such lump-sum payment would violate the Indenture, to the extent permitted by
the Indenture in equal monthly installments due and payable on the last day of
each month beginning on the last day of the month in which the Executives
employment is terminated and ending twelve (12) months thereafter or on such
later date as may be required for such payments to comply with the Indenture.
For purposes of this Section 9(h)(ii), Fair Value shall mean the
value of such Stock Option (without applying any discount for lack of control,
lack of liquidity, or similar factors) as determined by the Parties, or if they
are unable to agree promptly on such value, by an independent appraiser to be
mutually selected by the Parties. If the Parties are unable to agree promptly
upon an appraiser, each shall promptly designate an appraiser and the two
appraisers shall promptly select a third appraiser, who shall be the appraiser.
The appraiser shall be a nationally recognized United States investment banking
firm that has not at any time within the two years preceding its selection acted
in any capacity on behalf of the Company, its Affiliates or the Executive.

(iii)           In the event of any termination of the Executive's employment hereunder, he shall be under no
obligation to seek other
employment or otherwise mitigate the obligations of the Company under this
Agreement, and there shall be no offset against amounts due him on account of
(A) any Claim that the Company or any of its Affiliates may have against him or
(B) any remuneration or other benefit earned or received by him after such
termination (except as specifically provided in Section 9(d)(iv)). Any amounts
due under this Section 9 are considered to be reasonable by the Company and are
not in the nature of a penalty.

10.          Change in Control.

(a)         
In the event that a Change in Control occurs while the Executive is employed with the Company and the
Executive's employment with the Company is terminated in connection with, or in anticipation of, a Change in Control in a termination
that is governed by Section 9(d) or 9(e) (relating to terminations without Cause), (i) all outstanding Stock Options shall become
fully vested, fully exercisable and nonforfeitable, and shall remain exercisable for the remainder of their maximum stated terms,
(ii) any other amounts, entitlements and benefits in which he is not yet fully vested shall become fully vested and nonforfeitable,
(iii) the number specified in Section 9(d)(i)(B)(y) shall be deemed to be three (rather than two), and (iv) he shall be entitled to
additional or other benefits (if any) in accordance with applicable plans, programs and arrangements of the Company and its
Affiliates.  In the event that other holders of equity securities of the Company receive cash, securities or other property in
respect to such equity securities in connection with a Change in Control transaction, the Company shall use its best efforts to
enable the Executive (if he so elects) to exercise any Stock Option at a time and in a fashion that will entitled him to receive in
exchange for any securities thus acquired the same consideration as is received in such Change in Control transaction by other
holders of equity securities of the Company.

(b)         
In the event that any payment or benefit made or provided to or for the benefit of the Executive in
connection with this Agreement or his employment with the Company or the termination thereof (a "Payment") is determined to be
subject to any excise tax ("Excise Tax") imposed by Section 4999 of the Code (or any successor to such Section), the Company shall
pay to him, prior to the time any Excise Tax is payable with respect to such Payment (through withholding or otherwise), an
additional amount which, after the imposition of all income, employment, excise and other taxes thereon, is equal to the sum of (i)
the Excise Tax on such Payment plus (ii) any penalty and interest assessments associated with such Excise Tax plus (iii) an amount
equal to the product obtained by multiplying(A) the sum of any deductions disallowed for federal, state or local income tax purposes
because of the inclusion of any payment made by the Company under this Section 10(b) in his adjusted gross income times (B) the
highest applicable marginal rate of federal, state or local income taxation, respectively.  The determination of whether any Payment
is subject to an Excise Tax and, if so, the amount to be paid by the Company to the Executive and the time of payment pursuant to
this Section 10(b) shall be made by an independent auditor (the "Auditor") jointly selected by the Parties and paid by the Company.
Unless the Executive agrees otherwise in writing, the Auditor shall be a nationally recognized United States public accounting firm
that has not, during the two years preceding the date of its selection, acted in any way on behalf of the Company or any of its
Affiliates.  If the Parties cannot agree on the firm to serve as the Auditor, then each Party shall  select one accounting firm and
those two firms shall jointly select the accounting firm to serve as the Auditor.  The Parties shall cooperate with each other in
connection with any Proceeding or Claim relating to the existence or amount of any liability for Excise Tax.  All expenses relating
to any such Proceeding or Claim (including attorneys' fees and other expenses incurred by the Executive in connection therewith)
shall be paid by the Company promptly upon demand by the Executive, and any such payment shall (for the avoidance of doubt) be
subject to gross-up under this Section 10(b) in the event that the Executive is subject to Excise Tax on it.  The provisions of this
Section 10(b) shall apply whether or not a Change in Control shall have occurred.

11.           Indemnification.

(a)         
In the event that (x) the Executive is made a party, or is threatened to be made a party, to any Proceeding
by reason of the fact that he is or was a director, officer, employee, agent, manager, trustee, fiduciary, consultant or
representative of the Company or any of its Affiliates or is or was serving at the request of the Company or any of its Affiliates,
or in connection with his service hereunder, in any such capacity for any other Person, or (y) any Claim is made, or is threatened to
be made, that arises out of or relates to his service in any of the foregoing capacities, then the Executive shall promptly be
indemnified and held harmless by the Company to the fullest extent permitted by Delaware law against any and all costs, expenses,
liabilities and losses (including, without limitation, attorneys' fees, judgments, interest, expenses of investigation, penalties,
fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) incurred or suffered by him in connection
therewith or in connection with seeking to enforce his rights under this Section 11(a), and such indemnification shall continue as to
him even if he has ceased to be a director, member, employee, agent, manager, consultant or representative of the Company or other
Person and shall inure to the benefit of his heirs, executors and administrators.  He shall, in addition and to the maximum extent
permitted by Delaware law, be entitled to advancement by the Company of any and all costs and expenses (including, without
limitation, attorneys fees and costs of investigation) incurred by him in connection with any such Proceeding or Claim, or in
connection with seeking to enforce his rights under this Section 11(a), within 15 days after he gives written notice to the Company
requesting such advancement.  Such notice shall include, to the extent required by applicable law, an undertaking by the Executive to
repay to the Company the amount advanced if he is ultimately determined not to be entitled to indemnification against such costs and
expenses.

(b)         
During the Term and for a period of six years thereafter, a directors' and officers' liability insurance
policy (or policies) shall be kept in place providing (i) coverage to the Executive that is no less favorable to him in any respect
(including, without limitation, with respect to scope, exclusions, amounts, and deductibles) than the coverage then being provided to
any other present or former senior executive or director of the Company (or its Subsidiaries) and (ii) comprehensive aggregate
coverage in an amount not less than $50,000,000.

12.          Restrictive Covenants.

(a)          Confidentiality.          The Executive shall not at any time, without the prior written consent of the Company,
divulge, disclose or make accessible to any other Person any confidential non-public document, record or information concerning the
business or affairs of the Company that he has acquired in the course of his employment with the Company (including, without
limitation, this Agreement) except (i) to the Company, to any of its then current Affiliates, or to any authorized (or apparently
authorized) agent or representative of the foregoing, (ii) in connection with performing his duties hereunder, (iii) when required to
do so by law or by a court, governmental agency, legislative body, arbitrator or other Person with apparent jurisdiction to order him
to divulge, disclose or make accessible such information, (iv) in confidence to an attorney or other professional advisor for the
purpose of securing professional advice, (v) to the extent reasonably necessary to enforce legal rights, (vi) in the case of this
Agreement and other materials and information relating to his compensation, in confidence to members of his immediate family and
(vii) in the case of Section 12 of this Agreement, in confidence to any potential employer; provided that the restrictions set forth
in this Section 12(a) shall not apply to any document, record or other information that (x) has previously been disclosed to the
public or is in the public domain, other than as a result of the Executive's breach of this Section 12(a) or (y) is known or
generally available within any trade or industry of the Company or of any of its Affiliates.  The Company shall not, at any time,
disclose the terms and conditions of this Agreement to any third party, without the Executive's prior written consent (which consent
shall not be unreasonably withheld), except (x) in the circumstances described in clauses (iii), (iv) or (v) of the immediately

sole and exclusive property of the Company.  The Executive further agrees to assist in all ways reasonably deemed necessary by the
Company, and at the Company's sole expense, to protect such Inventions (including, without limitation, by executing, upon reasonable
request, documents for applications in the United States and foreign countries).

concerning the subject matter hereof and supersedes all prior agreements, understandings, term sheets, discussions, negotiations and
undertakings, whether written or oral, between them relating to this Agreement.  In the event of any inconsistency between any
provision of this Agreement and any provision of any plan, employee handbook, personnel manual, program, policy, arrangement or
agreement of the Company or any of its Affiliates, the provisions of this Agreement shall control unless the Executive otherwise
agrees in a writing that expressly refers to the provision of this Agreement whose control he is waiving.  This Agreement shall not,
however, displace accrued rights existing as of the Effective Date (including, without limitation, accrued rights under the 1997
Employment Agreement).

(b)           Amendment or Waiver.          No provision in this Agreement may be amended unless such amendment is set forth in a
writing that expressly refers to the provision of this Agreement that is being amended and that is signed by the Executive and by an
authorized (or apparently authorized) representative of the Company.  No waiver by any Person of any breach of any condition or
provision contained in this Agreement shall be deemed a waiver of any similar or dissimilar condition or provision at the same or any
prior or subsequent time.  To be effective, any waiver must be set forth in a writing signed by the waiving Person (or by an
authorized, or apparently authorized, representative of such Person) and must specifically refer to the condition(s) or provision(s)
of this Agreement being waived.

(c)         
Headings.          The headings of the Sections and sub-sections contained in this Agreement are for convenience

only and shall not be deemed to control or affect the meaning or construction of any provision of this Agreement.

(d)          Beneficiaries/References.          The Executive shall be entitled, to the extent permitted under applicable law,

to select and change a beneficiary or beneficiaries to receive any compensation or benefit hereunder following the Executive's death
by giving the Company written notice thereof.  In the event of the Executive's death or a judicial determination of his incompetence,
references in this Agreement to the Executive shall be deemed, where appropriate, to refer to his beneficiary, estate or other legal
representative.

(e)          Survivorship.          Except as otherwise set forth in this Agreement, the respective rights and obligations of

the Parties hereunder shall survive any termination of the Executive's employment.

(f)          Withholding Taxes.          The Company may withhold from any amounts or benefits payable under this Agreement

taxes that are required to be withheld pursuant to any applicable law or regulation.

(g)          Governing Law.          This Agreement shall be governed, construed, performed and enforced in accordance with its
express terms, and otherwise in accordance with the laws of the State of Delaware, without reference to principles of conflict of
laws.

(h)         Counterparts.          This Agreement may be executed in two or more counterparts, each of which shall be deemed an

original and all of which together shall be deemed to be one and the same instrument.

IN
WITNESS WHEREOF, the undersigned have executed this Agreement as of the date
first set forth above.

Telecommunications, Inc., a Delaware corporation (together with its successors

Parties agree as follows:

1.        Grant of the Option.    The Company hereby grants to the Participant the

Shares shall be $11.00 per Share (the Exercise Price). The Option is

shall vest and become exercisable and nonforfeitable with respect to one third (1/3) of the Shares initially covered by the Option on
each of the first, second, and third anniversaries of the Date of Grant.

(b)         In the event that the Participant's employment with the Company under the Employment Agreement terminates,
the Option shall immediately vest, and become exercisable and non-forfeitable, to the extent provided in Section 9 of the Employment
Agreement (or any successor to such section).

(c)        Notwithstanding any other provision of this Agreement to the contrary, in the event of any Change of
Control or Qualified Public Offering, the Option shall, to the extent not previously exercised or forfeited, immediately become fully
vested, fully exercisable and nonforfeitable.

3.        Exercise of Option.

(a)        Period of Exercise.  Subject to the provisions of the Plan and this Agreement, the Participant may exercise
all or any part of the portion of the Option that has become vested and exercisable pursuant to Section 2 (the "Vested Portion") at
any time prior to the earlier to occur of:

(ii)         the 90th day following the date of any termination of the Participant's employment with the
Company that is governed by Section 9(c) or 9(f) of the Employment Agreement (relating, respectively, to Cause and voluntary
termination) or any successor to such sections.

(b)        Method of Exercise.

(i)         Subject to Section 3(a) above, the Participant may exercise all or any portion of the Vested
Portion of the Option by
giving written notice to the Company at its principal office of his intent to
exercise that specifies the number of whole Shares for which the Option is being
exercised and that is accompanied by payment in full (or an arrangement for
payment in full) of the aggregate associated Exercise Price in accordance with
this Section 3(b)(i). The payment of the Exercise Price may be made (A) in cash,
or its equivalent, (B) by check or wire transfer, (C) by exchanging Shares owned
by the Participant (which are not the subject of any pledge or other security
interest and which have been owned by the Participant for at least 6 months)
whose fair value (determined without discount for lack of control, lack of
liquidity or similar factors) equals the Exercise Price, (D) if there shall be a
public market for the Shares as of the date of exercise, subject to such
reasonable rules as the Committee may establish (such rules to be promptly
established upon reasonable request from the Participant), through delivery of
irrevocable instructions to a broker to sell some or all of the Shares otherwise
deliverable upon the exercise of the Option and to deliver promptly to the
Company an amount equal to the aggregate Exercise Price, (E) with the consent of
the Committee (which consent shall not be unreasonably withheld or delayed), by
a full recourse five-year promissory note, with interest payable at maturity and
accruing at the lowest rate then permitted that avoids the imputation of income
under Code section 7872 or (F) by any combination of the foregoing.

(ii)         Promptly upon any exercise of the Option in accordance of the provisions of Section 3(a)(i) above,
the Company shall deliver
the purchased Shares to the Participant; provided that if any law or regulation,
or any regulation or rule of a national securities exchange or national market
system, requires the Company to take any action with respect to such Shares
before the delivery thereof, then the time for delivery of such Shares shall be
extended for the period necessary for the Company to complete such action, using
its best reasonable efforts. In connection with the acquisition of any Shares
pursuant to any exercise of the Option, the Participant shall make or enter into
such reasonable written representations, warranties and agreements as the
Committee may reasonably request in order to comply with applicable securities
laws or with this Agreement.

(iii)        In the event of the Participant's death, the Vested Portion of the Option, to the extent it has
not been transferred to a
Permitted Transferee as provided in Section 6 below, shall remain exercisable by
the Participants executor or administrator, or the person or persons to
whom the Participants rights under this Agreement shall pass by will or by
the laws of descent and distribution as the case may be, to the extent set forth
in Section 3(a). Any heir or legatee of the Participant shall take rights herein
granted subject to the terms and conditions hereof.

4.        No Right to Continued Employment. Neither the Plan nor this Agreement
shall be construed as giving the Participant the right to be retained in the
employ of, or in any consulting relationship to, the Company or any if its
Affiliates. Further, the Company or an Affiliate may at any time dismiss the
Participant or discontinue any consulting relationship, free from any liability
or any claim under the Plan or this Agreement, except as otherwise expressly
provided in this Agreement.

5.
        Legend on Certificates. The certificates representing the Shares
purchased by exercise of the Option shall be subject to such stop transfer
orders and other restrictions as the Committee may reasonably deem necessary
under the Plan, this Agreement, the rules, regulations, and other requirements
of the Securities and Exchange Commission, any stock exchange upon which such
Shares are listed, or any applicable Federal or state laws, and the Committee
may cause a legend or legends to be put on any such certificates to make
appropriate reference to such restrictions (which legend or legends shall be
promptly amended or removed on reasonable request by the Participant).

6.
        Transferability. The Option may not be assigned, alienated, pledged,
attached, sold or otherwise transferred or encumbered, in whole or in part, by
the Participant otherwise than by will or by the laws of descent and
distribution, and any such purported assignment, alienation, pledge, attachment,
sale, transfer or encumbrance shall be void and unenforceable against the
Company or any Affiliate; provided that the designation of a beneficiary (or
beneficiaries) to exercise all or part of the Option upon the Participants
death shall not constitute an assignment, alienation, pledge, attachment, sale,
transfer or encumbrance. Notwithstanding the foregoing, the Participant may
transfer the Option, in whole or in part, to a Permitted Transferee to the
maximum extent provided in Section 14 of the Plan as of the Date of Grant (or to
such greater extent as may subsequently be permitted under the Plan). No such
permitted transfer of the Option shall be effective to bind the Company unless
the Company shall have been furnished with written notice thereof and a copy of
such evidence as the Committee may reasonably deem necessary to establish the
validity of the transfer and the acceptance by the transferee or transferees of
the terms and conditions hereof. Any transferee shall, to the extent of the
transfer, succeed to all rights and obligations of the Participant under
Sections 3, 5, 6, 8 and 9 of this Agreement.

7.         Withholding.

(a)          The Participant may be required to pay to the Company, and the Company shall have the right and is hereby
authorized to withhold from any payment or transfer due under the Option or under the plan or from any compensation or other amount
otherwise owing to the Participant, the amount (in (A) cash, (B) Shares, other securities or other property whose fair value
(determined without discount for lack of liquidity, lack of control, or similar factors) equals such amount or (C) any combination of
the foregoing) of any applicable withholding taxes in respect of the Option, its exercise, or any payment or transfer under the
Option and to take such other action as may be necessary to satisfy all obligations for the payment of such taxes.

(b)              Without limiting the generality of Section 7(a) above, the Participant may satisfy, in whole or in part,
the foregoing withholding liability (A) by any of the methods specified in Section 3(b)(i), (B) by having the Company withhold from
the number of Shares otherwise issuable pursuant to the exercise of the Option a number of Shares with a Fair Market Value equal to
such withholding liability or (C) by any combination of the foregoing.

8.         
Adjustments.     In the event of any merger, consolidation, reorganization,
recapitalization, split-up, spin-off, combination, share exchange, liquidation,
dissolution, stock split, reverse stock split, cash dividend that is special and
non-recurring, stock dividend, distribution of stock or other property with
respect to shares or other securities, repurchase of shares or other securities,
or other change in corporate structure or capitalization affecting the rights or
value of the Shares, appropriate adjustment(s) shall be made in the number or
kind of equity securities subject to this Option and/or in the exercise price or
other terms and conditions of this Option, and/or appropriate provision shall be
made for supplemental payments of cash or other property, so as to avoid
dilution or enlargement of the rights of the Participant and of the after-tax
economic opportunity and value represented by this Option. Notwithstanding the
preceding sentence, in the event of any merger, consolidation or other
transaction (i) in which the Company is not the surviving entity or the Company
becomes a subsidiary of another entity; and (ii) following which the surviving
entity or its parent, or, if the Company survives as a subsidiary of another
entity, then such other entity or its parent, has publicly traded, equity
securities issued and outstanding, the Company shall use its best reasonable
efforts to assure that the Participant shall (at his election) be provided a
replacement option that (x) is exercisable for publicly traded equity securities
of the surviving entity (or of the parent of the surviving entity or of the
parent of the Company as the case may be) and (y) provides terms, conditions and
an after-tax economic opportunity (including, without limitation, an aggregate
spread value) no less favorable to the Participant than did this Option prior to
such transaction.

9.         Miscellaneous.

(a)          Any dispute arising out of or relating to this Agreement shall be resolved in accordance with Section 15 of
the Employment Agreement.

(b)          All notices relating to this Agreement shall be given as provided in Section 16 of the Employment
Agreement, except that notices to the Company shall be directed to the attention of the Secretary of the Company (or his or her
designee).

(c)          In the event of any inconsistency between any provision of this Agreement and any provision of the
Employment Agreement, the provisions of the Employment Agreement shall control.  In the event of any inconsistency between any
provision of this Agreement or of the Employment Agreement and any provision of the Plan, the provisions of this Agreement and of the
Employment Agreement shall control.

(d)          Sections 13(b), 14, 17(b), 17(c), 17(d), 17(e), 17(g) and 17(h) of the Employment Agreement (relating,
respectively, to assignments, representations, amendments/waivers, headings, beneficiaries/references, survivorship, governing law
and counterparts) shall be treated an incorporated herein in full, with references to the Executive being deemed to be references to
the Participant and with references to the Agreement being deemed to be references to this Agreement.

IN WITNESS WHEREOF, the Parties have executed this Agreement.
