                    SEPARATION AGREEMENT AND GENERAL RELEASE

     Quanta Capital Holdings Ltd., its subsidiaries and affiliates (collectively
referred to as "Quanta") and Michael J. Murphy, his heirs, executors,
administrators, successors, and assigns (collectively referred to as "Murphy"),
agree that:

1. LAST DAY OF EMPLOYMENT. Murphy's last day of employment with Quanta will be
July 25, 2006, herein referred to as the "termination of employment date," and
he will be paid all compensation through that date in accordance with Quanta's
normal payroll practices. For the purpose of the Consolidated Omnibus Budget
Reconciliation Act ("COBRA"), 29 U.S.C. ss. 1161 et seq., the "termination of
employment date" shall serve as the "qualifying event" for Murphy's rights under
COBRA. Murphy shall also resign from any and all positions at Quanta, including
his positions on the Quanta Board of Directors, the Boards of Directors of
Quanta subsidiaries on which he serves and as Chairman of the Office of
Strategic Innovation, effective July 25, 2006. Upon the full execution of this
Separation Agreement and General Release (the "Agreement"), Murphy shall execute
and deliver to Quanta the resignation letter annexed hereto as Exhibit A.

2. CONSIDERATION. In consideration for signing this Agreement and for compliance
with the promises made herein and subject to the conditions contained in this
Agreement, within ten (10) days of the full execution and delivery of this
Agreement, Quanta agrees to make a lump sum payment to Murphy in the amount of
two million dollars ($2,000,000.00) and a payment to Christine N. Kearns, Esq.
at Pillsbury Winthrop Shaw Pittman LLP, 2300 N. St. N.W. Washington, D.C. in the
amount of twenty-five thousand dollars ($25,000) for Murphy's legal fees in
connection with his separation. Should Quanta execute a letter of intent, or
other document to the same effect, for a transaction that would constitute a
"change of control" as defined in Section 1.01 of Murphy's Employment Agreement
dated July 17, 2003, as amended ("Employment Agreement"), within 90 days of
execution of this Agreement, and should such a transaction thereafter be
consummated, Quanta shall pay Murphy the amount he is due pursuant to Section
5.03 of the Employment Agreement, less the $2,000,000.00 set forth above. Such
change of control payment shall be made within thirty (30) days of any event
that would constitute a "change of control" as defined in the Employment
Agreement.

3. NO CONSIDERATION ABSENT EXECUTION OF THIS AGREEMENT. Murphy understands and
agrees that he would not receive the consideration specified in Paragraph 2
above, except for his execution of this Agreement and the fulfillment of the
promises contained herein. Murphy agrees and acknowledges that the payment
provided to him pursuant to this Agreement exceeds any payment, benefit or other
thing of value to which he would otherwise be entitled under any policy, plan or
procedure of Quanta or under any prior agreement (written or oral) between him
and Quanta.

4. NO REINSTATEMENT OR REEMPLOYMENT. Murphy agrees never to seek reemployment or
reinstatement with Quanta or any of its parent corporations, subsidiaries, or
affiliated entities. Murphy further agrees that he will not make application or
seek employment for any such positions at any time in the future, and agrees
that the execution of this Agreement is good and sufficient cause to reject any
such application or to terminate him if he obtains such future employment and
that such rejection or termination is not and will not be considered by him to
be retaliatory. Murphy represents that he

understands that he waives all rights to redress for any rejections of any
future applications by him for employment or reinstatement with Quanta as
described in this Paragraph.

5. MURPHY'S GENERAL RELEASE OF CLAIMS. For and in consideration of the payments
to be made and for other valuable consideration to be provided to Murphy
pursuant to this Agreement, Murphy for himself, his heirs, executors,
administrators, trustees, legal representatives, successors and assigns
(hereinafter collectively referred to as "Releasors"), hereby knowingly and
voluntarily releases and forever discharges Quanta and any of its past, present
or future parent entities, partners, subsidiaries, affiliates, divisions,
employee benefit and/or pension plans or funds, successors and assigns of each
and any of its or their past, present or future officers, directors, attorneys,
agents, trustees, administrators, employees, or assigns, in both their
representative and individual capacities, (hereinafter collectively referred to
as "Releasees") from any and all claims, demands, causes of action, debt or
liabilities of any kind (upon any legal or equitable theory, whether
contractual, common-law, statutory, federal, state, local or otherwise), whether
known or unknown, asserted or unasserted, by reason of any act, omission,
transaction, practice, plan, policy, procedure, conduct, occurrence or other
matter (collectively "claims") which Releasors may have against the Releasees,

nor anyone acting on his behalf, has made, filed, is party to, or will make or
file any charge, complaint or suit against any of the Releasees with any
federal, state or local court or agency. In the event that any action, suit,
claim, charge or proceeding is brought by any government agency, putative class
representative or other third party against Quanta, Murphy shall, except to the
extent required or compelled by law, legal process, or subpoena, refrain from
participating, providing assistance, testifying, or producing documents therein.
In the event Murphy is ordered to participate, provide assistance, testify, or
produce documents by a court, agency or regulatory authority, Murphy shall only
do so after he has given Quanta's General Counsel written notice, together with
all supporting legal papers or documents served upon him, within five business
days of his receipt of such notice. Murphy further affirms that upon Quanta's
full performance of the obligations in the Agreement, he will have been paid
and/or will have received all leave (paid and unpaid), compensation, wages,
bonuses, commissions, and or benefits to which he may have been entitled and
that no other leave (paid or unpaid), compensation, wages, bonuses,

                                       3

commissions and/or benefits are or will be due to him. . Murphy furthermore
affirms that he has no known workplace injuries or occupational diseases and has
been provided and/or has not been denied any leave requested under the Family
and Medical Leave Act.

8. CONFIDENTIALITY. Murphy shall hold in a fiduciary capacity for the benefit of
Quanta all secret, proprietary or confidential information, knowledge or data
relating to Quanta and its business that he has obtained that is not public
knowledge (other than as a result of Murphy's violation of this Paragraph 8)
("Confidential Information"). Moreover, both parties agree to hold the fact and
terms of this Agreement as confidential and agree not to disclose the fact or
terms of this Agreement except as required by law or regulation. This provision
does not prevent Murphy from divulging the fact or terms of this Agreement to
his spouse, tax advisor, and/or an attorney with whom Murphy chooses to consult
regarding his consideration of this Agreement. Murphy shall not communicate,
divulge or disseminate Confidential Information at any time, except with the
prior written consent of Quanta or as otherwise required by law or legal process
or in the carrying out of his duties under this Agreement. The parties
understand and agree that this confidentiality provision is a material term of
this Agreement.

9. MUTUAL NON-DISPARAGEMENT. Murphy agrees that he shall not make, participate
in the making of, or encourage or facilitate any other person to make, any
statements, written or oral, which criticize, disparage, or defame the goodwill,
reputation of, or which embarrass Quanta or any of its respective present,
former or future directors, officers, executives and/or employees. Murphy
further agrees that he shall not make, participate in the making of, or
encourage or facilitate any other person to make, any statements, written or
oral, which criticize, disparage, or defame the goodwill, reputation of, or
which embarrass shareholders. Murphy further agrees not to make any statements,
written or oral, relating to the termination of his employment or any non-public
and/or confidential aspects of the business of Quanta, except as may be required
by internal company investigation, court order or subpoena after providing
Quanta with notice as provided for in Paragraph 7 above. In turn, Quanta agrees
that it will use best efforts to not make, participate in the making of, or
encourage or facilitate any other person to make, any statements, written or
oral, which criticize, disparage, or defame the goodwill, reputation of, or
which embarrass Murphy. Quanta further agrees that it will use best efforts not
to make any statements, written or oral, relating to the termination of Murphy's
employment, except as may be required by internal company investigation, court
order or subpoena after providing Murphy with notice. Any alleged breach of this
Section 9 by either Murphy or Quanta shall not be deemed material unless the
breach is proven in a court of law. This Paragraph shall not be interpreted to
prevent Murphy or Quanta from providing truthful information in accordance with
any internal Quanta investigation or to any regulatory, judicial, administrative
or other governmental authorities as may be required by law or governmental
regulation.

10. COOPERATION. Murphy understands that Quanta may need to contact him to
obtain information regarding various business matters. Murphy agrees to respond
in a timely and reasonable fashion to Quanta's requests for such information.
Murphy also agrees to cooperate fully with Quanta with respect to any business
matter, including but not limited to ongoing or future litigation or
investigation, regulatory or otherwise, about which it is reasonably believed
that Murphy has knowledge, or with which he was involved, as a result of or
during his employment with Quanta. Such cooperation may include, without
limitation, providing information, meeting with Quanta representatives, or
testifying on Quanta's behalf. Should Murphy be required to retain counsel in
connection with the cooperation

                                       4

described in Paragraph 10, Quanta agrees to pay all of Murphy's reasonable legal
fees incurred in furtherance of such cooperation. Quanta reserves the right to
approve the necessity for counsel and Murphy's choice of counsel, but agrees
that either such approval will not be unreasonably withheld. In addition, Quanta
agrees to cooperate with Murphy with respect to producing documents currently
maintained on the Environmental Strategies Consulting ("ESC") servers that are
related to his unrelated business interests ("IRCC"), which are involved in
unrelated litigation. Murphy agrees to pay all costs associated with removing
the IRCC documents from the ESC servers, unless Quanta receives a subpoena to do
so from a party other than Murphy.

11. RETURN OF PROPERTY. Murphy shall permit a representative of Quanta to
inspect any material to be removed from Quanta's offices. By the termination of
employment date Murphy shall surrender to Quanta all property of Quanta in his
possession, including, without limitation, any and all intellectual property,
including models used in Quanta's business, documents, notes, records, manuals,
notebooks, computers, computer programs, cellular phones, security key cards,
credit cards, keys, pass cards and files, papers, electronically stored
information and documents kept or made by Murphy in connection with his
employment. Anything to the contrary notwithstanding, and in all cases
regardless of whether the information is retained in original form, as a copy,
electronically or otherwise, Murphy shall be entitled to retain (a) papers and
materials of a personal nature, including, without limitation, photographs,
correspondence, personal diaries, calendars and rolodexes, files relating to his
personal affairs and personal phone books, (b) information showing his
compensation or relating to reimbursement of expenses, (c) information he
reasonably believes may be needed for his personal tax purposes, and (d) any and
all material he obtained as a member of Quanta's Board of Directors, including,
but, not limited to, Board Books. By separate document, Murphy will certify that
he has complied with this Paragraph 11 of the Agreement. Should Quanta believe
that an item or document has not been returned it shall notify Murphy of such
belief in writing and provide Murphy 48 hours from receipt of said notice to
return the item or document articulated or make a certification that it has been
destroyed or surrendered.

12. RIGHTS AND OBLIGATIONS UNDER EMPLOYMENT AGREEMENT. Murphy acknowledges that,
except as provided herein and with respect to any right of indemnity he may have
as a former officer and director of Quanta, as of the termination of employment
date Murphy has no continuing rights under the Employment Agreement. Murphy
further acknowledges that all of his post-employment obligations to Quanta under
the Employment Agreement remain in full force and effect.

13. AGREED STATEMENT. Murphy may provide any person or entity inquiring about
the nature and cessation of Murphy's employment with Quanta with Exhibit B
hereto.

14. COMMUNICATIONS WITH QUANTA. By signing below, Murphy confirms that he does
not intend to, and will not, furnish Quanta with any correspondence on any
matter relating to Quanta's operations, policies or practices, the circumstances
surrounding his resignation, or any matter that he and Quanta believe to require
disclosure on a Form 8-K. Quanta intends to file a Current Report on Form 8-K
with the Securities and Exchange Commission as soon as practicable. A copy of
such current report has previously been provided to Murphy and, pursuant to Item
5.02(a)(3)(ii) of Form 8-K, Murphy will have the opportunity to furnish Quanta,
as promptly as possible, with a letter addressed to Quanta stating whether
Murphy agrees with the statements made by Quanta in response to such Item 5.02
and, if not, stating the respects in which Murphy does not agree. By signing
below, Murphy confirms that he does not intend to, and will not, furnish Quanta
with any such letter with respect to the statements made by Quanta in response
to such Item 5.02 of Form 8-K.

carefully read this Agreement in its entirety; (b) has had the opportunity to
take up to twenty-one (21) days to consider it and to consult with independent

during that time period; (c) fully understands the terms and conditions of this
Agreement; and (d) is signing this Agreement knowingly and voluntarily. Murphy

conformed in accordance with the laws of the state of New York without regard to
its conflict of laws provisions. In the event Murphy or Quanta breaches any
provision of this Agreement, Murphy and Quanta affirm that Murphy or Quanta may
institute an action to specifically enforce any term or terms of this Agreement.

any court of competent jurisdiction and cannot be modified to be enforceable,
excluding the general release language, such provision shall immediately become
null and void, leaving the remainder of this Agreement in full force and effect.
