whatsoever, both known and unknown, in law or in equity, involving any matter

obligations, duties and liabilities of the Company under the Employment
Agreement. Notwithstanding anything to the contrary herein, Donohue hereby
agrees to make himself available to the Company in connection with any dispute
or proceeding related to Jaco Electronics, Inc.

9. Indemnification of Donohue.

      A. Indemnification by the Company. To the fullest extent permitted by
applicable law (or any successor provision) and the Company's Articles of
Incorporation and Bylaws, the Company shall promptly indemnify Donohue for all
amounts (including, without limitation, judgments, fines, settlement payments,
losses, damages, costs and expenses (including reasonable attorneys' fees))
incurred or paid by Donohue in connection with any action, proceeding, suit or
investigation arising out of or relating to the performance by Donohue of
services for the Company, including as an employee, officer, director or
promoter of the Company.

      Promptly after receipt by Donohue of notice of the assertion of a claim
against him for actions related to such services, Donohue will give the Company
written notice of the assertion of such claim. If any claim is brought against
Donohue by means of a proceeding and Donohue gives written notice to the Company
of the commencement of such proceeding, the Company will be entitled to
participate in such proceeding and, to the extent that it wishes (unless (i) the
Company is also a party to such proceeding and Donohue determines in good faith
that joint representation would be inappropriate or (ii) the Company fails to
provide reasonable assurance to Donohue of its financial capacity to defend such
proceeding and provide indemnification with respect to such proceeding), to
assume the defense of such proceeding with counsel satisfactory to Donohue.
After written notice from the Company to Donohue of its election to assume the
defense of such proceeding, the Company will not, as long as it diligently
conducts such defense, be liable to Donohue under this indemnification for any
fees of other counsel or any other expenses with respect to the defense of such
proceeding, in each case subsequently incurred by Donohue in connection with the
defense of such proceeding, other than reasonable costs of investigation. If the
Company assumes the defense of a proceeding, (i) except for claims with respect
to willful misconduct or which indemnification would be contrary to state law,
it will be conclusively established for purposes of this indemnification that
the claims made in that proceeding are within the scope of and subject to
indemnification; and (ii) no compromise or settlement of such claims may be
effected by the Company without Donohue's consent, which consent Donohue shall
not unreasonably withhold. If written notice is given to the Company of the
commencement of any proceeding and the Company does not, within ten business
days after Donohue's written notice is given, give written notice to Donohue of
its election to assume the defense of such proceeding, the Company will be bound
by any determination made in such proceeding.

      To the extent that there is any discrepancy between the indemnification
provided under this Agreement and the Company's current Articles of
Incorporation or Bylaws, the document providing the broadest scope of
indemnification shall apply.

      B. Remedies of Donohue. In the event that payment has not been timely made
following a determination of entitlement to indemnification pursuant to this
Agreement, or Donohue otherwise seeks enforcement of this Agreement, and subject
to any applicable provision of law, Donohue shall be entitled to a final
adjudication in an appropriate court of his rights. Alternatively, and subject
to any applicable provision of law, Donohue at his option may seek an award in
arbitration to be conducted by a single arbitrator pursuant to the commercial
arbitration rules of the American Arbitration Association now in effect, whose
decision is to be made within ninety (90) days following the filing of the
demand for arbitration.

      10. Non-disparagement. Donohue and the Company shall (and the Company
shall cause its affiliates to) refrain from making any written or oral statement
or taking any action, directly or indirectly, which the other reasonably knows
or reasonably should know to be a disparaging or negative comment concerning the
other and shall refrain from suggesting that any such disparaging or negative
comment concerning the other be made except as may be compelled by a court of
competent jurisdiction. Neither the Company nor Donohue shall post, submit or
influence any information to any Internet "chat" site or Internet "posting
message board" with respect to the other.

      11. Binding Nature. All of the terms and provisions of this Agreement
shall be binding upon, inure to the benefit of, and be enforceable by the
parties and their respective legal representatives, successors and permitted
assigns, whether so expressed or not.

      12. Independent Representation. Each party hereto acknowledges and agrees
that it has received or has had the opportunity to receive independent legal
counsel of its own choice and that it has been sufficiently apprised of its
rights and responsibilities with regard to the substance of this Agreement.

      13. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which taken
together shall constitute one and the same instrument. Confirmation of execution
by electronic transmission of a facsimile signature page shall be binding upon
any party so confirming.

      14. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Florida, exclusive of conflicts or
choice of laws rules or comity and the parties hereto agree that any suit
brought hereunder shall be brought only in the Circuit Court for the Eleventh
Judicial Circuit in and for Miami-Dade County, Florida and the United States
District Court for the Southern District of Florida, Miami Division.

      15. Enforceability. If any provision (or portion thereof) of this
Agreement is adjudged invalid or unenforceable by a court of competent
jurisdiction, the remaining provisions shall nevertheless continue in full force
and effect. In any such case, the provision deemed unenforceable shall be remade
or interpreted by the parties in a manner that such provision shall be
enforceable to preserve, to the maximum extent possible, the original intention
and meaning thereof and such provision, as so modified or interpreted, shall
remain in full force and effect thereafter.

brought for the enforcement of any of the provisions of this Agreement, the
parties hereto agree that the prevailing party or parties shall be entitled to
recover from the other party or parties upon final judgment on the merits
reasonable attorneys' fees (and sales taxes thereon, if any), including
attorneys' fees for any appeal, and costs incurred in bringing such suit or
proceeding.

      17. Entire Agreement. This Agreement constitutes the entire agreement
between the parties hereto with respect to the subject matter hereof and
supersedes all prior negotiations, understandings, agreements, arrangements and
understandings, both oral and written, among the parties hereto with respect to
the subject matter hereof.
