Indemnification Agreement by and between the Company and Marilyn Lobel,
-----------------------------------------------------------------------
effective as of April 17, 2001.
-------------------------------

                              TUT SYSTEMS, INC.

                           INDEMNIFICATION AGREEMENT

  This Indemnification Agreement ("Agreement") is effective as of April 17, 2001
by and between Tut Systems, Inc., a Delaware corporation (the "Company"),and
Marilyn Lobel ("Indemnitee").

  WHEREAS, the Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve the Company and its related
entities;

  WHEREAS, in order to induce Indemnitee to continue to provide services to the
Company, the Company wishes to provide for the indemnification of, and the
advancement of expenses to, Indemnitee to the maximum extent permitted by law;

  WHEREAS, the Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for the Company's directors, officers, employees,
agents and fiduciaries, the significant increases in the cost of such insurance
and the general reductions in the coverage of such insurance;

  WHEREAS, the Company and Indemnitee further recognize the substantial increase
in corporate litigation in general, subjecting directors, officers, employees,
agents and fiduciaries to expensive litigation risks at the same time as the
availability and coverage of liability insurance has been severely limited; and

  WHEREAS, the Company and Indemnitee desire to continue to have in place the
additional protection provided by an indemnification agreement and to provide
indemnification and advancement of expenses to the Indemnitee to the maximum
extent permitted by Delaware law.


  NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

Certain Definitions.

on or after the date of this Agreement, (i) any "person" (as such term is used
in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934,as amended),
other than a trustee or other fiduciary holding securities under an employee
benefit plan of the Company acting in such capacity or a corporation owned
directly or indirectly by the stockholders of the Company in substantially the
same proportions as their ownership of stock of the Company, becomes the

indirectly, of securities of the Company representing more than 50% of the total
voting power represented by the Company's then outstanding Voting Securities,
(ii) during any period of two consecutive years, individuals who at the
beginning of such period constitute the Board of Directors of the Company and

election by the Company's stockholders was approved by a vote of at least two
thirds (2/3) of the directors then still in office who either were directors at
the beginning of the period or whose election or nomination for election was
previously so approved, cease for any reason to constitute a majority thereof,
or (iii) the stockholders of the Company approve 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) at least 80% of the total voting power represented by the Voting
Securities of the Company or such surviving entity outstanding immediately after
such merger or consolidation, or the stockholders of the Company approve a plan
of complete liquidation of the Company or an agreement for the sale or

pending or completed action, suit, proceeding or alternative dispute resolution

faith believes might lead to the institution of any such action, suit,

administrative, investigative or other.

  (c)  References to the "Company" shall include, in addition to Tut Systems,
Inc., any constituent corporation (including any constituent of a constituent)
absorbed in a consolidation or merger to which Tut Systems, Inc. (or any of its
wholly owned subsidiaries) is a party which, if its separate existence had
continued, would have had power and authority to indemnify its directors,
officers, employees, agents or fiduciaries, so that if Indemnitee is or was a
director, officer, employee, agent or fiduciary of such constituent corporation,
or is or was serving at the request of such constituent corporation as a
director, officer, employee, agent or fiduciary of another corporation,
partnership, joint venture, employee benefit plan, trust or other enterprise,
Indemnitee shall stand in the same position under the provisions of this
Agreement with respect to the resulting or surviving corporation as Indemnitee
would have with respect to such constituent corporation if its separate
existence had continued.

  (d)  "Covered Event" shall mean any event or occurrence related to the fact
that Indemnitee is or was a director, officer, employee, agent or fiduciary of

agreements).

  (h) References to "other enterprises" shall include employee benefit plans;
references to "fines" shall include any excise taxes assessed on Indemnitee with
respect to an employee benefit plan; and references to "serving at the request
of the Company" shall include any service as a director, officer, employee,

Directors, Independent Legal Counsel or any other person or body not a party to
the particular Claim for which Indemnitee is seeking indemnification.

  2.   Indemnification.
       ----------------

  (a)  Indemnification of Expenses. Subject to the provisions of Section 2(b)
       ---------------------------
below, the Company shall indemnify Indemnitee for Expenses to the fullest extent
permitted by law if Indemnitee was or is or becomes a party to or witness or
other participant in, or is threatened to be made a party to or witness or other
participant in, any Claim (whether by reason of or arising in part out of a
Covered Event), including all interest, assessments and other charges paid or
payable in connection with or in respect of such Expenses.

  (b)  Review of Indemnification Obligations. Notwithstanding the foregoing, in
       -------------------------------------
the event any Reviewing Party shall have determined (in a written opinion, in
any case in which Independent Legal Counsel is the Reviewing Party)that
Indemnitee is not entitled to be indemnified hereunder under applicable law, (i)
the Company shall have no further obligation under Section 2(a) to make any
payments to Indemnitee not made prior to such determination by such Reviewing
Party, and (ii) the Company shall be entitled to be reimbursed by Indemnitee
(who hereby agrees to reimburse the Company) for all Expenses theretofore paid
in indemnifying Indemnitee; provided, however, that if Indemnitee has commenced
                            --------- --------
or thereafter commences legal proceedings in a court of competent jurisdiction
to secure a determination that Indemnitee is entitled to be indemnified
hereunder under applicable law, any determination made by any Reviewing Party
that Indemnitee is not entitled to be indemnified hereunder under applicable law
shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expenses theretofore paid in indemnifying Indemnitee until a
final judicial determination is made with respect thereto (as to which all
rights of appeal therefrom have been exhausted or lapsed). Indemnitee's
obligation to reimburse the Company for any Expenses shall be unsecured and no
interest shall be charged thereon.

  (c)  Indemnitee Rights on Unfavorable Determination; Binding Effect. If any
       --------------------------------------------------------------
Reviewing Party determines that Indemnitee substantively is not entitled to be
indemnified hereunder in whole or in part under applicable law, Indemnitee shall
have the right to commence litigation seeking an initial determination by the
court or challenging any such determination by such Reviewing Party or any
aspect thereof, including the legal or factual bases therefor, and, subject to
the provisions of Section 15, the Company hereby consents to service of process
and to appear in any such proceeding. Absent such litigation, any determination
by any Reviewing Party shall be conclusive and binding on the Company and
Indemnitee.

  (d)  Selection of Reviewing Party; Change in Control. If there has not been a
       -----------------------------------------------
Change in Control, any Reviewing Party shall be selected by the Board of
Directors, and if there has been such a Change in Control (other than a Change
in Control which has been approved by a majority of the Company's Board of
Directors who were directors immediately prior to such Change in Control), any
Reviewing Party with respect to all matters thereafter arising concerning the
rights of Indemnitee to indemnification of Expenses under this Agreement or any
other agreement or under the Company's Certificate of Incorporation or Bylaws as
now or hereafter in effect, or under any other applicable law, if desired by
Indemnitee, shall be Independent Legal Counsel selected by Indemnitee and
approved by the Company (which approval shall not be unreasonably withheld).
Such counsel, among other things, shall render its written opinion to the
Company and Indemnitee as to whether and to what extent Indemnitee would be
entitled to be indemnified hereunder under applicable law and the Company agrees
to abide by such opinion.

The Company agrees to pay the reasonable fees of the Independent Legal Counsel
referred to above and to indemnify fully such counsel against any and all
expenses (including attorneys' fees), claims, liabilities and damages arising
out of or relating to this Agreement or its engagement pursuant hereto.
Notwithstanding any other provision of this Agreement, the Company shall not be
required to pay Expenses of more than one Independent Legal Counsel in
connection with all matters concerning a single Indemnitee, and such Independent
Legal Counsel shall be the Independent Legal Counsel for any or all other
Indemnitees unless (i) the Company otherwise determines or (ii) any Indemnitee
shall provide a written statement setting forth in detail a reasonable objection
to such Independent Legal Counsel representing other Indemnitees.

  (e)  Mandatory Payment of Expenses. Notwithstanding any other provision of
       -----------------------------
this Agreement other than Section 10 hereof, to the extent that Indemnitee has
been successful on the merits or otherwise, including, without limitation, the
dismissal of an action without prejudice, in defense of any Claim, Indemnitee
shall be indemnified against all Expenses incurred by Indemnitee in connection
therewith.

  3.   Expense Advances.
       -----------------

  (a)  Obligation to Make Expense Advances. Upon receipt of a written
       -----------------------------------
undertaking by or on behalf of the Indemnitee to repay such amounts if it shall
ultimately be determined that the Indemnitee is not entitled to be indemnified
therefor by the Company, the Company shall make Expense Advances to Indemnitee.

  (b)  Form of Undertaking. Any written undertaking by the Indemnitee to repay
       -------------------
any Expense Advances hereunder shall be unsecured and no interest shall be
charged thereon.

  (c)  Determination of Reasonable Expense Advances. The parties agree that for
       --------------------------------------------
the purposes of any Expense Advance for which Indemnitee has made written demand
to the Company in accordance with this Agreement, all Expenses included in such
Expense Advance that are certified by affidavit of Indemnitee's counsel as being
reasonable shall be presumed conclusively to be reasonable.

  4.   Procedures for Indemnification and Expense Advances.
       ----------------------------------------------------

  (a)  Timing of Payments. All payments of Expenses (including without
       ------------------
limitation Expense Advances) by the Company to the Indemnitee pursuant to this
Agreement shall be made to the fullest extent permitted by law as soon as
practicable after written demand by Indemnitee therefor is presented to the
Company, but in no event later than forty-five (45) business days after such
written demand by Indemnitee is presented to the Company, except in the case of
Expense Advances, which shall be made no later than twenty (20) business days
after such written demand by Indemnitee is presented to the Company.

  (b)  Notice/Cooperation by Indemnitee. Indemnitee shall, as a condition
       --------------------------------
precedent to Indemnitee's right to be indemnified or Indemnitee's right to
receive Expense Advances under this Agreement, give the Company notice in
writing as soon as practicable of any Claim made against Indemnitee for which
indemnification will or could be sought under this Agreement. Notice to the
Company shall be directed to the Chief Executive Officer of the Company at the
address shown on the signature page of this Agreement (or such other address as
the Company shall designate in writing to Indemnitee). In addition, Indemnitee
shall give the Company such information and cooperation as it may reasonably
require and as shall be within Indemnitee's power.

  (c)  No Presumptions; Burden of Proof. For purposes of this Agreement, the
       --------------------------------
termination of any Claim by judgment, order, settlement (whether with or without
court approval) or conviction, or upon a plea of nolo contendere, or its
                                                 ---------------
equivalent, shall not create a presumption that Indemnitee did not meet any
particular standard of conduct or have any particular belief or that a court has
determined that indemnification is not permitted by this Agreement or applicable
law. In addition, neither the failure of any Reviewing Party to have made a
determination as to whether Indemnitee has met any particular standard of
conduct or had any particular belief, nor an actual determination by any
Reviewing Party that Indemnitee has not met such standard of conduct or did not
have such belief, prior to the commencement of legal proceedings by Indemnitee
to secure a judicial determination that Indemnitee should be indemnified under
this Agreement or applicable law, shall be a defense to Indemnitee's claim or
create a presumption that Indemnitee has not met any particular standard of
conduct or did not have any particular belief. In connection with any
determination by any Reviewing Party or otherwise as to whether the Indemnitee
is entitled to be indemnified hereunder, the burden of proof shall be on the
Company to establish that Indemnitee is not so entitled.

  (d)  Notice to Insurers. If, at the time of the receipt by the Company of a
       -------------------
notice of a Claim pursuant to Section 4(b) hereof, the Company has liability
insurance in effect which may cover such Claim, the Company shall give prompt
notice of the commencement of such Claim to the insurers in accordance with the
procedures set forth in the respective policies. The Company shall thereafter
take all necessary or desirable action to cause such insurers to pay, on behalf
of the Indemnitee, all amounts payable as a result of such Claim in accordance
with the terms of such policies.

  (e)  Selection of Counsel. In the event the Company shall be obligated
       ---------------------
hereunder to provide indemnification for or make any Expense Advances with
respect to the Expenses of any Claim, the Company, if appropriate, shall be
entitled to assume the defense of such Claim with counsel approved by Indemnitee
(which approval shall not be unreasonably withheld) upon the delivery to
Indemnitee of written notice of the Company's election to do so. After


                                      49
<PAGE>

delivery of such notice, approval of such counsel by Indemnitee and the
retention of such counsel by the Company, the Company will not be liable to
Indemnitee under this Agreement for any fees or expenses of separate counsel
subsequently employed by or on behalf of Indemnitee with respect to the same
Claim; provided that, (i) Indemnitee shall have the right to employ Indemnitee's
separate counsel in any such Claim at Indemnitee's expense and (ii) if (A) the
employment of separate counsel by Indemnitee has been previously authorized by
the Company, (B) Indemnitee shall have reasonably concluded that there may be a
conflict of interest between the Company and Indemnitee in the conduct of any
such defense, or (C) the Company shall not continue to retain such counsel to
defend such Claim, then the fees and expenses of Indemnitee's separate counsel
shall be Expenses for which Indemnitee may receive indemnification or Expense
Advances hereunder.

Additional Indemnification Rights; Nonexclusivity.
-------------------------------------------------

  (a)  Scope. The Company hereby agrees to indemnify the Indemnitee to the
       ------
fullest extent permitted by law, notwithstanding that such indemnification is
not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the Company's Bylaws or by statute. In
the event of any change after the date of this Agreement in any applicable law,
statute or rule which expands the right of a Delaware corporation to indemnify a
member of its board of directors or an officer, employee, agent or fiduciary, it
is the intent of the parties hereto that Indemnitee shall enjoy by this
Agreement the greater benefits afforded by such change. In the event of any
change in any applicable law, statute or rule which narrows the right of a
Delaware corporation to indemnify a member of its board of directors or an
officer, employee, agent or fiduciary, such change, to the extent not otherwise
required by such law, statute or rule to be applied to this Agreement, shall
have no effect on this Agreement or the parties' rights and obligations
hereunder except as set forth in Section 10(a) hereof.

  (b)  Nonexclusivity. The indemnification and the payment of Expense Advances
       ---------------
provided by this Agreement shall be in addition to any rights to which
Indemnitee may be entitled under the Company's Certificate of Incorporation, its
Bylaws, any other agreement, any vote of stockholders or disinterested
directors, the General Corporation Law of the State of Delaware, or otherwise.
The indemnification and the payment of Expense Advances provided under this
Agreement shall continue as to Indemnitee for any action taken or not taken
while serving in an indemnified capacity even though subsequent thereto
Indemnitee may have ceased to serve in such capacity.

  6.   No Duplication of Payments. The Company shall not be liable under this
       --------------------------
Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received
payment(under any insurance policy, provision of the Company's Certificate of
Incorporation, Bylaws or otherwise) of the amounts otherwise payable hereunder.

  7.   Partial Indemnification. If Indemnitee is entitled under any provision
       ------------------------
of this Agreement to indemnification by the Company for some or a portion of
Expenses incurred in connection with any Claim, but not, however, for all of the
total amount thereof, the Company shall nevertheless indemnify Indemnitee for
the portion of such Expenses to which Indemnitee is entitled.

  8.   Mutual Acknowledgement.  Both the Company and Indemnitee acknowledge that
       -----------------------
in certain instances, federal law or applicable public policy may prohibit the
Company from indemnifying its directors, officers, employees, agents or
fiduciaries under this Agreement or otherwise. Indemnitee understands and
acknowledges that the Company has undertaken or may be required in the future to
undertake with the Securities and Exchange Commission to submit the question of
indemnification to a court in certain circumstances for a determination of the
Company's right under public policy to indemnify Indemnitee.

  9.   Liability Insurance.  To the extent the Company maintains liability
       --------------------
insurance applicable to directors, officers, employees, agents or fiduciaries,
Indemnitee shall be covered by such policies in such a manner as to provide
Indemnitee the same rights and benefits as are provided to the most favorably
insured of the Company's directors, if Indemnitee is a director; or of the
Company's officers, if Indemnitee is not a director of the Company but is an
officer; or of the Company's key employees, agents or fiduciaries, if Indemnitee
is not an officer or director but is a key employee, agent or fiduciary.


                                      50
<PAGE>

  10.   Exceptions.  Notwithstanding any other provision of this Agreement, the
        -----------
Company shall not be obligated pursuant to the terms of this Agreement:

  (a)  Excluded Action or Omissions.  To indemnify Indemnitee for Expenses
       -----------------------------
resulting from acts, omissions or transactions for which Indemnitee is
prohibited from receiving indemnification under this Agreement or applicable
law; provided, however, that notwithstanding any limitation set forth in this
Section 10(a) regarding the Company's obligation to provide indemnification,
Indemnitee shall be entitled under Section 3 to receive Expense Advances
hereunder with respect to any such Claim unless and until a court having
jurisdiction over the Claim shall have made a final judicial determination (as
to which all rights of appeal therefrom have been exhausted or lapsed) that
Indemnitee has engaged in acts, omissions or transactions for which Indemnitee
is prohibited from receiving indemnification under this Agreement or applicable
law.

  (b)  Claims Initiated by Indemnitee.  To indemnify or make Expense Advances to
       -------------------------------
Indemnitee with respect to Claims initiated or brought voluntarily by Indemnitee
and not by way of defense, counterclaim or crossclaim, except (i) with respect
to actions or proceedings brought to establish or enforce a right to
indemnification under this Agreement or any other agreement or insurance policy
or under the Company's Certificate of Incorporation or Bylaws now or hereafter
in effect relating to Claims for Covered Events, (ii) in specific cases if the
Board of Directors has approved the initiation or bringing of such Claim, or
(iii) as otherwise required under Section 145 of the Delaware General
Corporation Law, regardless of whether Indemnitee ultimately is determined to be
entitled to such indemnification or insurance recovery, as the case may be.

  (c)  Lack of Good Faith.  To indemnify Indemnitee for any Expenses incurred by
       -------------------
the Indemnitee with respect to any action instituted (i) by Indemnitee to
enforce or interpret this Agreement, if a court having jurisdiction over such
action determines as provided in Section 13 that each of the material assertions
made by the Indemnitee as a basis for such action was not made in good faith or
was frivolous, or (ii) by or in the name of the Company to enforce or interpret
this Agreement, if a court having jurisdiction over such action determines as
provided in Section 13 that each of the material defenses asserted by Indemnitee
in such action was made in bad faith or was frivolous.

  (d)  Claims Under Section 16(b).  To indemnify Indemnitee for expenses and the
       ---------------------------
payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of Section 16(b) of the Securities Exchange Act of
1934,as amended, or any similar successor statute; provided, however, that
notwithstanding any limitation set forth in this Section 10(d) regarding the
Company's obligation to provide indemnification, Indemnitee shall be entitled
under Section 3 to receive Expense Advances hereunder with respect to any such
Claim unless and until a court having jurisdiction over the Claim shall have
made a final judicial determination (as to which all rights of appeal therefrom
have been exhausted or lapsed) that Indemnitee has violated said statute.

  11.   Counterparts.  This Agreement may be executed in one or more
        -------------
counterparts, each of which shall constitute an original.

  12.   Binding Effect; Successors and Assigns.  This Agreement shall be binding
        --------------------------------------
upon and inure to the benefit of and be enforceable by the parties hereto and
their respective successors, assigns (including any direct or indirect successor
by purchase, merger, consolidation or otherwise to all or substantially all of
the business or assets of the Company), spouses, heirs and personal and legal
representatives. The Company shall require and cause any successor (whether
direct or indirect, and whether by purchase, merger, consolidation or otherwise)
to all, substantially all, or a substantial part, of the business or assets of
the Company, by written agreement in form and substance satisfactory to
Indemnitee, expressly to assume and agree to perform this Agreement in the same
manner and to the same extent that the Company would be required to perform if
no such succession had taken place. This agreement shall continue in effect
regardless of whether Indemnitee continues to serve as a director, officer,
employee, agent or fiduciary (as applicable) of the Company or of any other
enterprise at the Company's request.

  13.   Expenses Incurred in Action Relating to Enforcement or Interpretation.
        ------------------------------------------------------ ---------------
In the event that any action is instituted by Indemnitee under this Agreement or
under any liability insurance policies maintained by the Company to enforce or
interpret any of the terms hereof or thereof, Indemnitee shall be entitled to be
indemnified for all Expenses incurred by Indemnitee with respect to such action
(including without limitation attorneys' fees), regardless of whether Indemnitee
is ultimately successful in such action, unless as a part of such action a court
having jurisdiction over such action makes a final judicial determination (as to
which all rights of appeal therefrom


                                      51
<PAGE>

have been exhausted or lapsed) that each of the material assertions made by
Indemnitee as a basis for such action was not made in good faith or was
frivolous; provided, however, that until such final judicial determination is
made, Indemnitee shall be entitled under Section 3 to receive payment of Expense
Advances hereunder with respect to such action. In the event of an action
instituted by or in the name of the Company under this Agreement to enforce or
interpret any of the terms of this Agreement, Indemnitee shall be entitled to be
indemnified for all Expenses incurred by Indemnitee in defense of such action
(including without limitation costs and expenses incurred with respect to
Indemnitee's counterclaims and cross-claims made in such action), unless as a
part of such action a court having jurisdiction over such action makes a final
judicial determination (as to which all rights of appeal therefrom have been
exhausted or lapsed) that each of the material defenses asserted by Indemnitee
in such action was made in bad faith or was frivolous; provided, however, that
until such final judicial determination is made, Indemnitee shall be entitled
under Section 3 to receive payment of Expense Advances hereunder with respect to
such action.

  14.   Notice.  All notices, requests, demands and other communications under
        -------
this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and signed for by the party addressed, on the date of such
delivery, or (ii) if mailed by domestic certified or registered mail with
postage prepaid, on the third business day after the date postmarked. Addresses
for notice to either party are as shown on the signature page of this Agreement,
or as subsequently modified by written notice.

  15.   Consent to Jurisdiction.  The Company and Indemnitee each hereby
        ------------------------
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be commenced, prosecuted and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be
the exclusive and only proper forum for adjudicating such a claim.

  16.   Severability.  The provisions of this Agreement shall be severable in
        -------------
the event that any of the provisions hereof (including any provision within a
single section, paragraph or sentence) are held by a court of competent
jurisdiction to be invalid, void or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including without limitation each portion of this Agreement containing any
provision held to be invalid, void or otherwise unenforceable, that is not
itself invalid, void or unenforceable) shall be construed so as to give effect
to the intent manifested by the provision held invalid, illegal or
unenforceable.

  17.   Choice of Law.  This Agreement, and all rights, remedies, liabilities,
        --------------
powers and duties of the parties to this Agreement, shall be governed by and
construed in accordance with the laws of the State of Delaware without regard to
principles of conflicts of laws.

  18.   Subrogation.  In the event of payment under this Agreement, the Company
        ------------
