                                ESCROW AGREEMENT

          THIS ESCROW AGREEMENT, dated as of April 16, 2003, is by and among Med
Diversified, Inc., a Nevada corporation, and Trestle Corp., a Delaware
corporation (collectively, the "SELLERS"), Trestle Acquisition Corp., a Delaware

                               W I T N E S S E T H

          WHEREAS, Sellers and Buyer are parties to that certain Asset Purchase
Agreement (the "AGREEMENT"), dated as of April 16, 2003, pursuant to which
Sellers propose to sell, and Buyer proposes to acquire, certain Assets, as
defined in the Agreement,1 upon the terms and conditions set forth in such
agreement, subject to Bankruptcy Court approval; and

          WHEREAS, pursuant to, and subject to the terms and conditions of, this
Escrow Agreement, Buyer has agreed to deliver to Escrow Agent a deposit, in the
amount of $100,000 (the "DEPOSIT"), to be held in escrow pursuant to the terms
of this Escrow Agreement and the Agreement; and

          WHEREAS, Escrow Agent acts, and will continue to act, as counsel to
Sellers in connection with, among other things, this Escrow Agreement and the
Agreement; and

          WHEREAS, the parties have agreed that Escrow Agent may act as Escrow
Agent hereunder and may represent Sellers, and each of them, in the event of any
dispute regarding this Escrow Agreement or any other matter, including those
involving the Buyer and, including without limitation, the Sellers' bankruptcy
cases; and

          WHEREAS, this Escrow Agreement, a copy of which is attached as EXHIBIT
A to the Agreement, is intended to reflect and serve as the escrow agreement
among the parties hereto with respect to the Deposit.

          NOW, THEREFORE, in consideration of the mutual covenants herein
contained and for other good and valuable consideration, the mutual receipt and
legal sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

          1. APPOINTMENT OF ESCROW AGENT; FORMATION OF THE ESCROW.

                1.1    Upon the Escrow Agent's receipt of a duly and properly
executed copy of this Escrow Agreement and the Deposit, the Escrow Agent agrees
to act as Escrow Agent pursuant to the terms of this Escrow Agreement and the
Agreement. The parties hereto hereby authorize and instruct the Escrow Agent to
retain possession of the Deposit in escrow (the "ESCROW") and to disburse the
Deposit in accordance with the terms of this Escrow Agreement.

                1.2    The Escrow Agent shall hold the Deposit in an interest
bearing escrow account to be maintained by the Escrow Agent at Citizens Bank,
and which account shall

----------
1 Capitalized terms, not otherwise defined herein, shall have the meaning

be designated as an escrow account. If the Escrow Agent changes the account in
which any or all of the Deposit is held, then the Escrow Agent shall promptly,
but no more than five (5) business days after the date of such change, notify
all parties of the name of the bank, the account number, and account name where
any or all of the Deposit will be deposited.

          2. RELEASE OF THE DEPOSIT. The Escrow Agent shall hold the Deposit
until it delivers the Deposit as provided in this Section 2.

                2.1    NOTIFICATION AND ACTION. The Escrow Agent shall not make
any distributions of the Deposit except as specifically set forth below. The
Escrow Agent only shall make a distribution of the Deposit or a portion thereof
if so instructed, upon the following:

                     (a)    receipt of written instructions signed jointly by
Buyer and Sellers (the "JOINT INSTRUCTIONS") stating the following:

                            (i)      upon the Closing of the sale of the Assets
as provided in the Agreement, that the Deposit be delivered to Sellers by
federal funds wire transfers of immediately available funds in no event later
than on the Closing Date; or

                            (ii)     if the Agreement is terminated pursuant to
Section 10.01(a), (c), (d), (e) or (g) of the Agreement, that the Deposit be
delivered to Buyer; or

                            (iii)    if the Agreement is terminated pursuant to
Section 10.01(b) of the Agreement, that (A) Fifty Thousand Dollars ($50,000) of
the Deposit be delivered to Buyer, and (B) the remaining Fifty Thousand Dollars
($50,000) of the Deposit be delivered to the Sellers; or

                            (iv)     if the agreement is terminated pursuant to
Section 10.01(f), that the Deposit be delivered to the Sellers;

     In the case of Sections 2.1(a)(ii)-(iv), the Deposit, or a portion thereof,
shall be delivered to the relevant party by federal funds wire transfers of
immediately available funds in no event later than one (1) business day
following the date of termination;

          or

                (b)    receipt of an order of a court of competent jurisdiction
directing the distribution of the Deposit or a portion thereof (a "COURT
ORDER").

     As promptly as practicable after receipt by the Escrow Agent of the Joint
Instructions or the Court Order, the Escrow Agent shall deliver the Deposit, or
any designated portion thereof, to the party or parties in the manner set forth
in the Joint Instructions or the Court Order, as the case may be; PROVIDED,
HOWEVER, that in all events, the Buyer and Sellers agree that solely Buyer shall
receive any interest earned on the Deposit.

                2.2    CONFLICTING NOTIFICATION. In the event of any conflicting
instructions, the Escrow Agent, in its sole and absolute discretion, shall:

                                       -2-
<Page>

                     (a)    continue to hold the portion of the Deposit which is
the subject of such conflicting instructions until the earlier of (x) its
receipt of a final and non-appealable court order from a court of competent
jurisdiction (in form and substance satisfactory to the Escrow Agent, in its
sole and absolute discretion) directing it to deliver such portion of the
Deposit in accordance with the terms of such court order, in which event the
Escrow Agent shall deliver such portion of the Deposit in accordance therewith
or (y) its receipt of written instructions signed jointly by Buyer and Sellers
directing it to deliver such Deposit in accordance with the terms of such
instructions, in which event the Escrow Agent shall deliver such portion of the
Deposit in accordance therewith; or

                     (b)    at any time after the five day period following the
Escrow Agent's receipt of such conflicting instructions, deliver the portion of
the Deposit which is the subject of such conflicting instructions into the
control of a court of competent jurisdiction, in which event the Escrow Agent
shall have no further obligations or responsibilities with respect thereto.
Notwithstanding the foregoing, the Escrow Agent shall deliver the Deposit, or a
portion thereof, in accordance with the terms of any written instructions
jointly executed by Buyer and Sellers to the extent that such instructions are
received by the Escrow Agent prior to its delivery of the Deposit to a court of
competent jurisdiction in accordance with this clause (b).

          3. TERMINATION OF THE ESCROW. The Escrow Agent shall terminate the
Escrow, and the Escrow Agent's duties shall terminate, upon release of the
Deposit in accordance with Section 2 of this Escrow Agreement.

          4. INDEMNIFICATION/RELEASE

                4.1    In the event of any controversy or threatened controversy
of whatever nature, arising out of, regarding or relating to any aspect of or to
the Escrow, the Deposit or this Escrow Agreement (and regardless of whether or
not such controversy or threatened controversy involves litigation, mediation,
arbitration or other mechanism for dispute resolution), each of the parties
hereto, jointly and severally, bind and obligate themselves and their respective
successors, heirs, executors and assigns to indemnify and hold the Escrow Agent
harmless from and against any claim, loss, liability or expense, and for all
reasonable costs and expenses, including the reasonable fees and expenses of the
Escrow Agent's counsel, incurred in connection with such controversy or
threatened controversy, except as a result of the Escrow Agent's own gross
negligence or willful misconduct. The provisions of this paragraph shall survive
the termination of this Escrow Agreement.

          5. DUTIES OF THE ESCROW AGENT.

                5.1    The duties and obligations of the Escrow Agent shall be
determined solely by the express provisions of this Escrow Agreement and the
Escrow Agent shall not be liable or responsible except for the performance of
such duties and obligations as are specifically set forth in this Escrow
Agreement.

                5.2    The Escrow Agent shall not in any way be bound or
affected by any modification or cancellation of this Escrow Agreement unless in
writing signed by the Escrow Agent and each of the parties hereto. The Escrow
Agent shall be entitled to rely upon any notice, certification, demand or other
writing delivered to the Escrow Agent hereunder in

                                       -3-
<Page>

accordance with the terms hereof without being required to determine the
authenticity or the correctness of any fact stated therein, the propriety or
validity of the service thereof, or the jurisdiction of the Court issuing any
judgment or order.

                5.3    The Escrow Agent may act in reliance upon any signature
reasonably believed by the Escrow Agent to be genuine, and may assume that any
person purporting to give any notice or receipt, or make any statements in
connection with the provisions hereof has been duly authorized to do so. Without
limiting the generality of the immediately preceding sentence, the persons
executing this Escrow Agreement on behalf of each of the parties hereto shall be
assumed by the Escrow Agent as being the duly authorized representative of that
party; provided however, that such signatory may instruct the Escrow Agent in
writing to recognize another person or persons as a party's authorized
signatory.

                5.4    The Escrow Agent shall not be required to institute or
defend any action (including interpleader) or legal process involving any matter
referred to herein which in any manner affects the Escrow Agent or the Escrow
Agent's duties or liabilities hereunder.

          6. RIGHT OF INTERPLEADER. Should any controversy arise with respect to
this Escrow Agreement or the Deposit, or the right of any party or other person
to receive the Deposit, or should the Escrow Agent be in doubt as to what action
to take, the Escrow Agent shall either (i) withhold delivery of the Deposit
until the controversy is resolved, the conflicting demands are withdrawn or the
Escrow Agent's doubt is resolved as evidenced by a joint written agreement of
the parties to the controversy or by a final and nonappealable order of a court
of competent jurisdiction, each in accordance with the provisions of Section
2.2, if applicable, or (ii) institute a bill of interpleader in any court of
competent jurisdiction to determine the rights of the parties hereto (the right
of the Escrow Agent to institute such bill of interpleader shall not, however,
be deemed to modify the manner in which the Escrow Agent is entitled to make
disbursements of the Deposit, as set forth above, other than to tender the
Deposit into the registry of such court or as otherwise directed by such court).
Should a bill of interpleader be instituted, or should the Escrow Agent be
threatened with litigation or become involved in litigation in any manner
whatsoever on account of this Escrow Agreement or the Deposit, except as a
result of the Escrow Agent's own gross negligence or willful misconduct, then,
as between themselves and the Escrow Agent, the parties hereto, jointly and
severally, hereby bind and obligate themselves, their successors, heirs,
executors and assigns to pay the Escrow Agent its reasonable attorneys' fees and
any and all other reasonable costs, disbursements, expenses, losses and damages
of the Escrow Agent in connection with or resulting from such threatened or
actual litigation.

          7. NOTICES.

                7.1    Any notice required or permitted to be given hereunder
shall be in writing and shall be (i) personally delivered, (ii) transmitted by
nationally recognized overnight courier, (iii) transmitted by registered or
