Dear Ricardo:

         The purpose of this letter ("LOI") is to set forth certain binding
understandings and agreements between Radiation Therapy Services, Inc. ("RTSI"),
Devoto Construction, Inc. ("Devoto") and its shareholders (the "Devoto
shareholders") with respect to the acquisition (the "Acquisition") by RTSI of
all of the outstanding capital stock or all of the assets of Devoto (the
"Transaction"). All terms and conditions of the Transaction shall be pursuant to
all applicable federal, state and local laws.

         The terms of the Transaction shall be as follows:

         1.       Consideration. The consideration to be paid by RSTI to the
                  Devoto Shareholders under the Transaction will be $3,528,000,
                  payable at the closing of the Transaction (the "Closing") in
                  shares of restricted common stock of RTSI. The aggregate
                  number of shares to be issued to the Devoto Shareholders shall
                  be based on the initial public offering price per share of
                  RTSI common stock.

         2.       Conduct of Business. Pending the execution and delivery of the
                  definitive acquisition agreement and the Closing, Devoto
                  agrees to conduct its business as follows, unless otherwise
                  approved in writing by RTSI:

                  a.       Devoto's business shall be conducted in substantially
                           the same manner as it has been
                           conducted to date.

                  b.       Devoto will not incur any new debt mortgage, pledge,
                           security interest, lien or restriction of any kind.

                  c.       Devoto will not discharge or satisfy any claims,
                           liabilities or obligations other than in the usual or
                           ordinary course of business.

         3.       Closing Date. The Closing will occur simultaneously on the
                  date of the closing of RTSI's initial public offering (the
                  "Closing Date").
<PAGE>

         4.      Definitive Documentation. Additional terms and conditions of
                 the Transaction will be set forth in a definitive acquisition
                 agreement (the "Agreement") which terms and conditions shall be
                 customary for stock or asset purchase transactions between
                 related parties. The structure of the Transaction as either a
                 purchase of stock or assets shall be in RTSI's sole discretion.

         5.      Termination of Covenants. Unless extended in writing by the
                 parties hereto, the obligations contained in paragraph 2 shall
                 terminate in the event that the Agreement has not been executed
                 by all of the parties hereto on or before the Closing Date (as
                 such date may be extended by the parties as provided herein).

         Until this LOI is replaced by the definitive Agreement between the
parties, it is the intent of the parties that this LOI shall be binding on the
parties and their respective successors and assigns.

Very truly yours,

RADIATION THERAPY SERVICES, INC.

                                                                   EXHIBIT 10.61

                              EMPLOYMENT AGREEMENT

This Employment Agreement (the "Agreement") is entered into effective as of
March 29, 2004 (the "Effective Date") by and between Critical Path, Inc. (the
"Company") and Mark Ferrer ("Executive") (collectively referred to herein as the
"Parties")

The Company desires to appoint Executive to the position of Chief Executive
Officer ("CEO") for an indeterminate term and to have the benefits of his
expertise and knowledge. Executive, in turn, desires to be employed by the
Company as its CEO. The Parties, therefore, enter into this Agreement to
establish the terms and conditions of Executive's employment with the Company.

In consideration of the mutual covenants and representations contained in this
Agreement, the Company and Executive agree as follows:

1.       EMPLOYMENT OF EXECUTIVE; DUTIES. The Company agrees to employ
Executive, and Executive agrees to be employed by the Company, as the CEO of the
Company. In his role as CEO, Executive shall report to the Board of Directors
(the "Board"). As the CEO, Executive's key duties will include the normal and
customary duties of such position and such other duties as the Board shall
determine from time to time. Executive will use his specialized expertise,
independent judgment and discretion in executing his job duties. Executive shall
devote all of his working time, interest and efforts reasonably necessary to the
fulfillment of his duties and responsibilities under this Agreement. It is
acknowledged by the parties that such efforts will require travel in connection
with performing Executive's duties hereunder. The Executive may engage in
non-competitive business or charitable activities for reasonable periods of time
each month so long as such activities do not interfere with the Executive's
responsibilities under this Employment Agreement.

2.       EMPLOYMENT PERIOD. Executive shall serve as CEO until discharged by the
Board or his employment is otherwise terminated pursuant to Section 12 below.

3.       PLACE OF EMPLOYMENT. Executive understands and agrees that his services
will be performed at the Company's principal offices in San Francisco,
California (the "Bay Area") as well as at a Company corporate office to be
established in the Washington DC/Northern Virginia area (the "DC Office"). It is
the Company's current intention that, within six months of the commencement of
Executive's employment under this Agreement, it will develop a presence in the
DC Office which may include representatives from various departments or business
units within the Company, and the Executive is authorized to develop the DC
Office in his reasonable discretion (subject to the approval of the Board). It

                                       1
<PAGE>

is agreed that the rights and obligations provided in this Section shall
constitute material terms of this agreement.

4.       BASE SALARY. During his employment as CEO, the Company shall pay
Executive at the rate of Three Hundred Seventy-Five Thousand Dollars ($375,000)
per year, to be paid in accordance with the Company's standard payroll practices
(the "Base Salary"). Executive's salary shall be subject to annual review, based
on corporate policy and contributions made by Executive to the Company. Based
upon such annual review, Executive's salary may be increased, but cannot be
decreased.

5.       BONUS COMPENSATION. Provided Executive's employment has not been
terminated by the Company for Cause or by the Executive without Good Reason,
Executive will be eligible to earn and receive annual bonus compensation,
payable in cash as soon as practicable following completion of the Company's
audited financial statements for each full fiscal year, commencing with the 2004
fiscal year, subject to the following:

Executive is eligible for a target annual bonus of 50% of Base Salary (using the
rate of Base Salary as of the end of the applicable fiscal year) upon achieving
performance objectives that were established by the Board (or a committee of the
Board). The actual amount of the bonus paid to Executive, if any, shall be
determined by the Board (or a committee of the Board) and such bonus amount may
be as high as 150% of Base Salary for achievement of extraordinary performance.
The milestones for bonus awards at both the 50% and 150% levels shall be
mutually agreed upon by the Executive and the Board, and the parties agree that
the milestones for 2004 shall be set within 90 days after Executive commences
his employment. In future years, the milestones will be identified within 90
days of the commencement of the relevant fiscal year.

6.       EQUITY COMPENSATION. Executive will be granted compensatory equity
which shall be conditioned on Executive's execution of agreements with the
Company documenting the terms and conditions of such grants. All compensatory
equity grants shall also be subject to the terms and conditions of the
applicable granting plan ("Stock Plan") and Company policies, including without
limitation, the Company's insider trading policy.

         6.1      Stock Options. On the Effective Date of this Agreement,
Executive shall receive a stock option grant enabling Executive to purchase up
to one and one-half percent (1.5%) of the Company's outstanding common shares on
a "Diluted" basis measured as of the Effective Date. These options shall be
incentive stock options to the maximum extent allowed by the tax code. For
purposes of this Agreement, "Diluted" means giving effect to the possible
conversion of debt instruments and

                                       2
<PAGE>

preferred shares into common shares, as well as all other convertible
instruments including the possible exercise of all outstanding stock options,
but not including the grants to Executive. The granted stock options shall have
a ten year term and shall vest 12.5% on the date that is six (6) months after
the Effective Date and thereafter shall vest on a pro-rata monthly basis over
the ensuing forty-two (42) months. Vesting shall cease upon the termination of
Executive's employment and service as a Board member (collectively "Service")
and such unvested options shall also then be immediately canceled and forfeited
to the Company without consideration. The per share option exercise price shall
be equal to the fair market value of a Company common share on the date of
option grant. All unexercised stock options shall expire on the earlier of (i)
the tenth anniversary of the date of grant, (ii) twelve months after cessation
of Executive's Service, (iii) the date of termination of Executive's employment
(and/or service as a Board member) by the Company for Cause or (iv) such other
date provided under the terms of the Stock Plan or applicable agreement. Except
as provided herein, this stock option grant shall be governed by the terms of
the Stock Option Agreement, executed by the parties, in the form attached
hereto.

         6.2      Restricted Stock. On the Effective Date of this Agreement,
Executive shall receive a grant of restricted Company common shares in an amount
equal to one percent (1%) of the Company's outstanding common shares on a
Diluted basis measured as of the Effective Date. Such restricted stock shall
vest 12.5% on the date that is six (6) months after the Effective Date and
thereafter shall vest on a pro-rata quarterly basis over the ensuing fourteen
quarters. All unvested restricted shares shall be held in escrow by the Company.
Vesting shall cease upon the termination of Executive's Service and such
unvested shares shall then be immediately forfeited to the Company without
consideration. Executive must timely satisfy all tax withholding obligations
resulting from vesting of the restricted stock before the release from escrow of
any vested shares to Executive. Except as provided herein, this restricted stock
grant shall be governed by the terms of the Restricted Stock Agreement, executed
by the parties, in the form attached hereto.

         6.3      Additional Equity Grants. As soon as reasonably practicable
following completion or termination of the Company's proposed rights offering to
shareholders to acquire Series E Redeemable Convertible Preferred Stock, the
Company will make a second grant of stock options and restricted stock to
Executive if necessary so that Executive's aggregate equity stake is 2.5% of the
Company's outstanding common shares on a Diluted basis. The terms and conditions
for these second grants shall be as provided for the grants specified in
Sections 6.1 and 6.2

                                       3
<PAGE>

provided, however, that the fair market value of a common share and the vesting
start dates for the second grants will each be based on the date of the second
grants. In addition, (i) the number of shares underlying the stock options
granted under this Section 6.3 shall be such that the sum of the stock option
shares granted under Sections 6.1 and 6.3 equals one and one-half percent (1.5%)
of the Company's outstanding common shares and (ii) the number of restricted
shares granted under this Section 6.3 shall be such that the sum of the
restricted shares granted under Sections 6.2 and 6.3 equals one percent (1%) of
the Company's outstanding common shares, each on a Diluted basis measured as of
the date of second grant.

7.       CORPORATE ACCOMMODATIONS; EXPENSES. During such time period that
Executive has not relocated his principal residence to the Bay Area and when
Executive is performing Company business in the Bay Area, the Company shall: (i)
provide Executive with the use of a corporate apartment in the Bay Area for
Executive to reside in during his time in the Bay Area (not to exceed $3,000 per
month), (ii) pay for Executive's coach air travel to the Bay Area and (iii)
provide Executive with auto transportation in the Bay Area in the form of a car
lease not to exceed $500 per month.

Executive will also be reimbursed for all reasonable and necessary business
expenses (including, but without limitation, travel expenses) upon the properly
completed submission of requisite forms and receipts to the Company. Such
reimbursements shall be in compliance with Company policy and any applicable
laws and regulations.

8.       EMPLOYEE BENEFITS.

         8.1.     Benefits. While Executive is employed by the Company,
Executive will be entitled to participate in the same employee benefits plans
generally available to the Company's other executive and managerial employees,
subject to the terms of the applicable plans, including: (i) all health
insurance benefits provided to the Company's exempt employees; (ii) paid
vacation in accordance with the Company's policies and procedures in effect with
respect to the Company's other senior officers (for which the days selected for

sharing or other retirement plan maintained by the Company for its executive
employees.

         8.2.     Insurance. During Executive's employment as CEO, the Company
shall maintain life insurance coverage for Executive in an amount equal to two
times Base Salary.

                                       4
<PAGE>

9.       INDEMNIFICATION BY THE COMPANY. To the extent Executive is acting as a
director, manager, officer, or employee of the Company or fiduciary of any
employee benefit plan, or serving or having served any other entity as a
director, manager, officer, or executive or fiduciary of any employee benefit
plan at the Company's request, he shall be indemnified and held harmless by the
Company, to the fullest extent allowed by law, the Company's charter and
by-laws.

Executive shall be entitled to coverage under the Company's directors and
officers liability insurance policy in effect at any time in the future to no
lesser extent than any other officers or directors of the Company. After
Executive is no longer CEO, the Company shall keep in effect its standard
post-employment coverage on Executive.

10.      NON-DISCLOSURE OF CONFIDENTIAL AND PROPRIETARY INFORMATION. Executive

11.      DEVELOPED INFORMATION. Executive agrees to promptly disclose and assign

Company.

         12.1     At-Will Employment. Executive's employment pursuant to this

uncured "Constructive Termination" (collectively, a "Qualifying Termination")
then, subject to Section 12.3, Executive shall be offered the following:

     a. Twelve (12) monthly, substantially equal, payments that in the aggregate
     equal: (i) Base Salary plus (ii) a pro-rata payment (based on the number of
     days Executive served as CEO in the fiscal year of termination) of

                                       6
<PAGE>

     Executive's actual bonus (if any) paid to him under Section 5 for the
     fiscal year prior to the year of termination;

     b. Continuation of group health benefits (excluding life insurance and
     disability) provided by the Company for up to twelve (12) months following
     termination of employment (where Executive will continue to pay his share
     of the applicable costs as if he were still an employee), with his
     qualifying event for purposes of COBRA being deemed to have occurred upon
     the expiration of this twelve (12) month continuation period; and

     c. Twelve (12) months of accelerated vesting of Executive's outstanding
     unvested stock options and unvested restricted shares.

         12.3     Change in Control. If a Qualifying Termination occurs within
twelve (12) months after a "Change in Control" of the Company (as defined below)
or if a Qualifying Termination occurs within three (3) months before a Change in
Control that Executive can demonstrate would not have occurred absent such
Change in Control, then in lieu of the severance payments and benefits offered
by Section 12.2, Executive shall instead be offered the following:

     a. A single cash lump sum payment in an amount equal to 1.5 times Base
     Salary payable on the later of the (i) eighth day following Executive's
     execution (and non-revocation) of the "Release" (as defined in Section
     12.9) or (ii) the date of the Change in Control;

     b. Continuation of group medical benefits (excluding life insurance and
     disability) provided by the Company for up to eighteen (18) months
     following termination of employment (where Executive will continue to pay
     his share of the applicable costs as if he were still an employee); and

     c. Accelerated vesting of (i) the greater of seventy-five percent (75%) or
     twelve (12) months of Executive's unvested restricted shares and (ii)
     twelve (12) months of accelerated vesting of Executive's outstanding
     unvested stock options.

Any payments that may have been previously paid to Executive under Section 12.2
shall be subtracted from payments to be made to Executive under Section 12.3.
For purposes of this Agreement, a Change in Control shall mean the occurrence of
any of the following events:

                                       7
<PAGE>

     (i) the approval by the shareholders of the Company of a plan of complete
     liquidation of the Company or an agreement for the sale or disposition by
     the Company of all or substantially all of the Company's assets;

     (ii) the approval by shareholders of the Company of a merger or
     consolidation of the Company with any other corporation, other than a
     merger or consolidation which would result in the voting securities of the
     Company outstanding immediately prior thereto continuing to represent
     (either by remaining outstanding or by being converted into voting
     securities of the surviving entity) more than fifty percent (50%) of the
     total voting power represented by the voting securities of the Company or
     such surviving entity outstanding immediately after such merger or
     consolidation;

     (iii) any "person" (as such term is used in Sections 13(d) and 14(d) of the
     Securities Exchange Act of 1934, as amended) becoming the "beneficial
     owner" (as defined in Rule 13d-3 under said Act), directly or indirectly,
     of securities of the Company representing thirty percent (30%) or more of
     the total voting power represented by the Company's then outstanding voting
     securities; or

     (iv) a change in the composition of the Board, as a result of which fewer
     than sixty-six percent (66%) of the directors are Incumbent Directors.
     "Incumbent Directors" shall mean directors who either (A) are directors of
     the Company as of the date hereof or (B) are elected, or nominated for
     election, to the Board with the affirmative votes of at least a majority of
     those directors whose election or nomination was not in connection with any
     transactions described in subsections (i), (ii) or (iii), or in connection
     with an actual or threatened proxy contest relating to the election of
     directors of the Company.

     Notwithstanding the foregoing, the term "Change in Control" shall not be
     deemed to have occurred if the Company files for bankruptcy protection, or
     if a petition for involuntary relief is filed against the Company.

In the event that it is determined that any payment or distribution of any type
to or for Executive's benefit made by the Company, by any of its affiliates, by
any person who acquires ownership or effective control or ownership of a
substantial portion of the Company's assets (within the meaning of Section 280G
of the Internal Revenue Code of 1986, as amended, and the regulations thereunder
(the "Code")) or by any affiliate of such person, whether paid or payable or
distributed or distributable

                                       8
<PAGE>

pursuant to the terms of an employment agreement or otherwise, would be subject
to the excise tax imposed by Section 4999 of the Code or any interest or
penalties with respect to such excise tax (such excise tax, together with any
such interest or penalties, are collectively referred to as the "Excise Tax"),
then such payments or distributions or benefits shall be payable either: (x) in
full or (y) as to such lesser amount which would result in no portion of such
payments or distributions or benefits being subject to the Excise Tax. Executive
shall receive the greater, on an after-tax basis, of (x) or (y) above.

         12.4     Cause. For purposes of this Agreement, "Cause" means that
Executive has committed any one or more of the following (and which, in the case
of Sections 12.4(b) or (d), remains uncured by Executive to the Board's

Company's written notice of such breach by Executive):

     a. Commission of a felony or an act constituting common law fraud;

     b. Intentional or willful misconduct or refusal to follow the lawful
     instructions of the Board;

     c. Intentional Breach of Company confidential information obligations which
     has a material adverse effect on the Company or its affiliates or
     stockholders; or

     d. A material breach of this Agreement.

     For these purposes, no act or failure to act shall be considered
     "intentional or willful" unless it is done, or omitted to be done, in bad
     faith without a reasonable belief that the action or omission is in the
     best interests of the Company. The Company may terminate Executive's
     employment for Cause at any time without advance notice in the cases of
     Sections 12.4(a) and 12.4(c).

         12.5     Constructive Termination. For purposes of this Agreement,
Executive's resignation of employment as a result of "Constructive Termination"
means that any of the following has occurred without Executive's consent (and
which remains uncured by the Company within fifteen (15) days of the Company's
receipt of the Executive's written notice of such breach by the Company):

     a. A material diminution in Executive's title, duties, or compensation;

                                       9

<PAGE>

     b. Any change in ownership or corporate structure which results in
     Executive no longer being CEO of a stand-alone publicly traded company
     through no fault of Executive;

     c. The Company's material breach of this Agreement.

     d. failure of the Company to obtain or maintain coverage for Executive
     under an appropriate directors and officers liability insurance policy.

         12.6     Termination for Cause or Death. Upon any termination of
Executive's employment (i) by the Company for Cause or (ii) due to the
Executive's death, the Company will have no further obligation to make any
payment to Executive, under this Agreement or otherwise, except for the Base
Salary and vacation accrued as of the date of termination. In addition,
Executive's entitlement to participate in any Company benefit plans shall
immediately cease as of the date of termination, except as otherwise required by
law, and all unvested compensatory equity (and unvested shares held in escrow)

of the period following any notice of termination given by either party. During
his employment and thereafter, Executive shall also fully cooperate in the
defense of any action brought by any third party against the Company that

Company or in the defense of any action brought by any third party relating to
litigation pending against the Company as of the termination of Executive's
employment, and the Company will reimburse Executive for the costs associated
with this, including for any time spent on such matters subsequent to his

no longer utilize any Company property and will not make or retain copies,
reproductions or summaries of any such property.

Company and its affiliates and affiliated persons within sixty days after

comply with his post-employment obligations to the Company in order to receive
and continue to receive such payments/benefits. Any coverage provided by Section
12.2(b) or Section 12.3(b), as applicable, shall terminate if and when Executive

that such coverage is reasonably comparable to the coverage provided by the
Company and does not include any limitation affecting pre-existing conditions.

13.      NATURE OF EMPLOYMENT. Executive represents to the Company that he has
no other outstanding commitments and that he also is not subject to any
agreements) inconsistent with any of the terms of this Agreement or the services
to be provided in accordance with this Agreement. In addition, while employed
with the Company, Executive shall not, whether for compensation or otherwise,
directly or indirectly perform any services or acts for any person or entity who
is in competition with any business, services or products being offered for sale
or produced by the Company. Executive shall also not own an interest in,
participate in or be connected as an officer, employee, agent, independent
contractor, partner, shareholder or principal, of any corporation, partnership,
proprietorship, firm, association, person, or other entity that directly or
indirectly competes with the services and business of Company.

14.      NONSOLICITATION; NONDISPARAGEMENT.

         14.1     Clients. Executive understands and agrees that all customers
or clients of the Company for which Executive provides services during
Executive's employment are solely the clients of the Company and not of
Executive. Executive agrees that both while employed and for a period of one (1)
year after the termination of his employment for any reason, Executive shall
not, either directly or indirectly, solicit business, as to products or services
competitive with those of the Company, from any of the Company's clients or
prospective clients. It shall not be a violation of this policy for Executive to
solicit these

                                       11
<PAGE>

clients or prospective clients in a manner that is not intended to reduce or
otherwise adversely affect the amount of business they are doing with the
Company.

         14.2     Employees. Executive understands and agrees that the Company
has invested substantial time and effort and resources in assembling, training
and managing its present staff of personnel, which constitutes a significant
asset of the Company. Accordingly, Executive agrees that both while employed and
for a period of one (1) year after the termination of his employment for any
reason, Executive will not directly or indirectly induce or solicit or encourage
any of the Company's employees to leave their employment with the Company. It
shall not be a violation of this policy for Executive to place, or cause to be
placed, an advertisement in a newspaper or other periodical of general
circulation generally soliciting applicants for employment and to consider for
employment any Company employees who respond to such advertisement, as long as
such advertisement is not specifically targeted at Company employees.

         14.3     Nondisparagement. During the term of their employment
relationship and at all times thereafter, and regardless of any dispute that may
subsequently arise between the parties, the parties hereto mutually agree that
they will not make or cause to be made any disparaging written or oral remarks
or statements about the other, or, as applicable, their respective affiliates,
employees, officers, directors, shareholders, agents, representatives, heirs,
successors, assigns, service providers or suppliers or take any other action(s)
that might be harmful to the business or reputation of such persons or entities.

15.      NOTICES. Any notices, requests, demands and other communications
provided for by this Agreement shall be sufficient if in writing and if sent by
registered or certified mail to Executive at the last address he has filed in
writing with the Company, with a copy to his counsel, or, in the case of the
Company, to the General Counsel at the Company's principal executive offices.

16.      BINDING AGREEMENT. This Agreement shall be binding upon Executive and
the Company on and after the Effective Date. The rights and obligations of the
Company under this Agreement shall inure to the benefit of the Company and any
successor(s) or assign(s) of the Company.

17.      INTEGRATION. This Agreement constitutes the entire understanding of
Executive and the Company with respect to the subject matter herein and
supersedes and voids any and all prior agreements or understandings, written or
oral, regarding the subject matter hereof. To the extent any of the plans or

                                       12
<PAGE>

agreements referenced herein are inconsistent with this Agreement, the terms of
this Agreement shall control. This Agreement may not be changed, modified, or
discharged orally, but only by an instrument in writing signed by the Parties.

18.      CONSTRUCTION. Each party has reviewed this Agreement. Therefore the
normal rule of construction that any ambiguity or uncertainty in any writing
shall be interpreted against the party drafting the writing shall not apply to
any action on this Agreement.

19.      GOVERNING LAW. This Agreement shall be governed by the laws of the
State of California, and the invalidity or unenforceability of any provisions
hereof shall in no way affect the validity or enforceability of any other
provision.

20.      SEVERABILITY. Any provision of this Agreement which is prohibited or
unenforceable by any court of competent jurisdiction will immediately become
null and void, leaving the remainder of this Agreement in full force and effect.
Any such prohibition or unenforceability in any court of competent jurisdiction
shall not invalidate or render unenforceable such provision in any other
jurisdiction.

21.      MANDATORY ARBITRATION. The Parties agree that any future controversy,
claim or dispute arising out of or related to Executive's employment or the
termination of his employment shall be resolved by binding arbitration, except
where the law specifically forbids the use of arbitration as a final and binding
remedy, or where Section 21(e) below specifically allows a different remedy.

         a. The Parties agree that the dispute shall be resolved by binding
         arbitration before a single arbitrator mutually agreed upon by the
         Parties and applying the Commercial Arbitration Rules of the American
         Arbitration Association. The Company shall bear the costs of the
         arbitration proceeding, but each party shall bear its own legal fees.

         b. The arbitrator shall have the authority to determine whether the
         conduct complained of violates the complainant's rights and, if so, to
         grant any relief authorized by law; subject to the exclusions of
         Section 21(e) below. The arbitrator shall not have the authority to
         modify, change, or refuse to enforce the terms of this Agreement.

         c. The arbitrator shall award the prevailing party in the arbitration
         its attorneys' fees.

                                       13
<PAGE>

         d. Arbitration shall be the exclusive final remedy for any dispute
         between the Parties including but not limited to any disputes or claims
         for discrimination or harassment (such as claims under the Fair
         Employment and Housing Act, Title VII of the Civil Rights Act of 1964,
         the Americans with Disabilities Act, or the Age Discrimination in
         Employment Act), wrongful termination, breach of contract, breach of
         public policy, physical or mental harm or distress, or any other
         disputes.

         e. Notwithstanding the arbitration provisions set forth herein, the
         Parties reserve their right to seek an injunction or other equitable
         relief from a court with applicable authority. Executive acknowledges
         that in the event of any breach of any provision of Sections 10, 11, or
         14 of this Agreement, the Company would be irreparably and immediately
         harmed and could not be made whole by monetary damages. It is
         accordingly agreed that the Company shall be entitled to seek an
         injunction to prevent breach of this Agreement and to compel specific
         performance of this Agreement, in addition to any other remedy to which
         it may be entitled in law or equity. To the extent any portion of
         Sections 10, 11 or 14 of this Agreement is deemed by the court to be
         overly restrictive as to time, scope or geographical area, the Parties
         agree that the court shall have the authority to reform the unlawful
         provision to be in conformance with the law, with the Parties'
         agreement that Sections 10, 11 and 14 are to be given the fullest force
         and effect permissible by law.

         f. The arbitrator shall issue a written arbitration decision stating
         the arbitrator's essential findings and conclusions upon which any
         award is based. A party's right to review of the decision is limited to
         the grounds provided under applicable law. The Parties agree that the
         arbitration award shall be enforceable in any court having jurisdiction
         to enforce this Agreement.

22.      WITHHOLDING. All payments or benefits made under this Agreement to
Executive shall be subject to applicable tax withholding laws and regulations.
Executive shall be required to fully satisfy any such withholding as a condition
of receipt of any payments or benefits.

23.      ATTORNEY FEES. The Company shall directly pay Executive's legal counsel
an amount not to exceed $12,000 for reasonable fees and expenses incurred in
connection with the negotiation and execution of this Agreement. Executive's
counsel shall provide the Company with sufficiently detailed invoices (including
task descriptions of work performed) itemizing such fees and expenses.

                                       14

24.      OUTSTANDING LITIGATION MATTERS. The Company acknowledges that it is not
presently a party to any material litigation other than as described in the FY
2003 10-K filed with the Securities & Exchange Commissions on March 15, 2004.
The Company further acknowledges that this representation was material to
Executive's consideration of the Company's offer of employment hereunder, and
that any misrepresentation regarding the pendency of litigation against the
Company as of the date this Agreement is executed would constitute a material
breach of this Employment Agreement.

IN WITNESS WHEREOF, the Parties have executed and delivered this Agreement as of
the date first above written.
