Employment Agreement - Net2Phone Inc. and Clifford M. Sobel

Employment Forms

  • Employment Contract. Employers can customize an employment agreement that states the salary, benefits, working hours and other important provisions for their new or existing employee.
  • Consulting Agreement. Answer simple questions to build a contract with a consultant. Specify the services rendered, when payment is due, as well as IP rights.
  • Commission Agreement. Employers who compensate their sales employees based on commissions can prepare an agreement to reduce misunderstandings by specifying the base salary and how commissions are calculated.
  • Executive Employment Agreement. Companies may offer their business executives a contract that is different from the one provided to their regular employees. Executive employment agreements may be more complex because the compensation structure may include a combination of salary and commissions, provide for bonuses based on sales, stock or other financial targets, and include non-compete, confidentiality and severance provisions.
  • Sales Representative Contract. Independent sales representatives offer companies the potential to increase the sale of products or services without the burden of increasing headcount. Both parties should understand how commissions are calculated, when commissions will be paid, as well as how the representative will treat confidential information from the company and whether the representative may also sell a competing line of products or services.

equity interests that do not exceed five percent (5%) of such class of equity)
or (2) directly or indirectly solicit or encourage any employee of the Company
or any of its affiliates to leave the employment of the Company or any of its
affiliates. For purposes hereof, the "Restricted Period" shall be the Agreement
Term (as may be terminated pursuant to Section 6 hereof) and, except in the
event of a termination described in Section 6(a) hereof, the 12-month period
following any termination of the Executive's employment hereunder.

                  (c) Enforcement. The Executive acknowledges and agrees that
the Company will have no adequate remedy at law, and could be irreparably
harmed, if the Executive breaches or threatens to breach any of the provisions
of Section 11 of this Agreement. The Executive agrees that the Company shall be
entitled to equitable and/or injunctive relief to prevent any breach or
threatened breach of this Section 11, and to specific performance of each of the
terms of this Section in addition to any other legal or equitable remedies that
the Company may have. The Executive further agrees that he shall not, in any
equity proceeding relating to the enforcement of the terms of this Section 11,
raise the defense that the Company has an adequate remedy at law.

                  12. SUCCESSORS AND ASSIGNS

                  (a) This Agreement shall be binding upon and shall inure to
the benefit of the Company, its successors and any person or other entity that
succeeds to all or substantially all of the business, assets or property of the
Company. To the extent not otherwise provided by application of law, the Company
will require any successor (whether direct or indirect, by purchase, merger,
consolidation, transfer or otherwise) to all or substantially all of the
business, assets or property of the Company, to expressly assume and agree to
perform the obligations of the Company under this Agreement in the same manner
and to the same extent that the Company is required to perform hereunder. As
used in this Agreement, the "Company" shall mean the Company as hereinbefore
defined and any successor to its business, assets or property as aforesaid which
executes and delivers an agreement provided for in this Section 12(a) or which
otherwise becomes bound by all the terms and provisions of this Agreement by
operation of law. Except as provided by the foregoing provisions of this Section
12(a), this Agreement shall not be assignable by the Company without the prior
written consent of the Executive. In the event that this Agreement is assigned
to any person or entity as may be permitted hereunder, the Company shall be
secondarily liable in the event that any such person or entity shall fail to
satisfy its obligations under Section 6 or 7 hereof.

                  (b) This Agreement and all rights of the Executive hereunder
shall inure to the benefit of and be enforceable by the Executive's personal or
legal representatives, executors, administrators, successors, heirs,
distributees, devisees and legatees. If the Executive should die while any
amounts are due and payable to the

                                       9
<PAGE>   10
Executive hereunder, all such amounts, unless otherwise provided herein, shall
be paid to the Executive's designated beneficiary or, if there is no such
designated beneficiary, to the legal representatives of the Executive's estate.
This Agreement is personal in nature and the obligations of the Executive
hereunder are not be assignable to any person.

                  13. ENTIRE AGREEMENT/AMENDMENT

                  This Agreement contains the entire understanding of the
parties with respect to the subject matter hereof and, except as specifically
provided herein, cancels and supersedes any and all other agreements between the
parties with respect to the subject matter hereof. Any amendment or modification
of this Agreement shall not be binding unless in writing and signed by the
parties hereto.

                  14. SEVERABILITY/NO WAIVER

                  (a) In the event that any provision of this Agreement is
determined to be invalid or unenforceable, the remaining terms and conditions of
this Agreement shall be unaffected and shall remain in full force and effect,
and any such determination of invalidity or unenforceability shall not affect
the validity or enforceability of any other provision of this Agreement.

                  (b) The failure of a party to insist upon strict adherence to
any term of this Agreement or any occasion shall not be considered a waiver of
such party's rights or deprive such party of the right thereafter to insist upon
strict adherence to that term or any other term of this Agreement.

                                    EXHIBIT A

                               REGISTRATION RIGHTS



                  SECTION  1.1  Piggyback Registrations.

                  (a) Right to Piggyback Registration. Whenever the Company
proposes to register any of its Common Stock (or securities convertible into or
exchangeable or exercisable for Common Stock) under the Securities Act of 1933,
as amended (the "Securities Act") for its own account or the account of any
stockholder of the Company (other than offerings pursuant to employee benefit
plans, or noncash offerings in connection with a proposed acquisition, exchange
offer, recapitalization or similar transaction) (a "Piggyback Registration"),
the Company will give written notice as promptly as practicable to the Executive
and to all other holders of Common Stock having similar registration rights, of
its intention to effect such a registration and shall include in such
registration all Registrable Shares with respect to which the Company has
received written request for inclusion therein and which have not been reduced
pursuant to Section 1.1(b) or 1.1(c) below within 15 days after receipt of the
Company's notice. Capitalized terms used but not defined in this Exhibit A shall
have the meanings ascribed to such terms in Section 1.11.

                  (b) Priority on Primary Registrations. If a Piggyback
Registration is an underwritten primary registration on behalf of the Company,
and the managing underwriters advise the Company in writing that in their
opinion the number of securities requested to be included in such registration
exceeds the number which can be sold in an orderly manner in such offering
within a price range acceptable to the Company, the Company shall include in
such registration (i) first, the securities the Company proposes to sell, (ii)
second, the securities requested to be included in such registration basis held
by any holder exercising piggyback registration rights (other than holders of
Registrable Shares) and (iii) third, the Registrable Shares requested to be
included in such registration, pro rata among the holders of such securities on
the basis of the number of shares requested to be included in such registration
by such holder.



                  (c) Priority on Secondary Registrations. If a Piggyback
Registration is an underwritten secondary registration on behalf of holders of
the Company's securities, and the managing underwriters advise the Company in
writing that in their opinion the number of securities requested to be included
in such registration exceeds the number which can be sold in an orderly manner
in such offering within a price range acceptable to the holders of a majority of
the securities who are demanding the registration in question, the Company shall
include in such registration (i) first, the securities requested to be included
therein by the holders requesting such registration, and the securities
requested to be included in such registration held by any holder exercising
piggyback registration rights (other than holders of Registrable Shares), and
(ii) second, the

                                       1

<PAGE>   15
Registrable Shares requested to be included in such registration, pro rata among
the holders of such securities on the basis of the number of shares requested to
be included in such registration by such holder.



                  SECTION 1.2  Registration Procedures. If and whenever the
Company is required to effect or cause the registration of any Registrable
Shares under the Securities Act as provided in this Agreement, the Company
shall:

                  (a) notify the Executive of any stop order issued or
threatened by the Securities and Exchange Commission ("SEC") and take all
reasonable actions required to prevent the entry of such stop order or to remove
it if entered;

                  (b) furnish, without charge, to the Executive and each
underwriter, if any, such number of copies of the applicable Registration
Statement, each amendment and supplement thereto (including one signed copy to
the Executive and one signed copy to each managing underwriter and in each case
including all exhibits thereto), and the Prospectus included in such
Registration Statement (including each preliminary prospectus), in conformity
with the requirements of the Securities Act, and such other documents as the
Executive may reasonably request in order to facilitate the disposition of the
Registrable Shares registered thereunder;

                  (c) use commercially reasonable efforts to register or qualify
such Registrable Shares covered by such Registration Statement under such other
securities or blue sky laws of such jurisdictions within the United States of
America as the selling holders, and the managing underwriter, if any, reasonably
request and do any and all other acts and things which may be reasonably
necessary or advisable to enable the selling holders and each underwriter, if
any, to consummate the disposition in such jurisdictions of the Registrable
Shares registered thereunder; provided, however, that the Company shall not be
required to (i) qualify generally to do business in any jurisdiction where it
would not otherwise be required to qualify but for this paragraph (c), (ii)
subject itself to taxation in any such jurisdiction or (iii) consent to general
service of process in any such jurisdiction;

                  (d) as promptly as practicable notify the managing
underwriter, if any, the Executive and the other selling holders, if any, at any
time when a Prospectus relating thereto is required to be delivered under the
Securities Act, of the happening of any event if, as a result of such event, the
Prospectus included in such Registration Statement contains an untrue statement
of a material fact or omits to state any material fact required to be stated
therein or necessary to make the statements therein not misleading, and the
Company shall as promptly as practicable prepare and furnish to the selling
holders a supplement or amendment to such Prospectus so that, as thereafter
delivered, such Prospectus shall not contain an untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading;

                                       2

<PAGE>   16
                  (e) use commercially reasonable efforts to cause all such
securities being registered to be listed on each securities exchange, market
system or interdealer quotation system on which similar securities issued by the
Company are then listed, and enter into such customary agreements including a
listing application and indemnification agreement in customary form, and to
provide a transfer agent and registrar for such Registrable Shares covered by
such Registration Statement no later than the effective date of such
Registration Statement;

                  (f) make available for inspection by the Executive or any
holder of securities covered by such Registration Statement, any underwriter
participating in any distribution pursuant to such Registration Statement, and
any attorney, accountant or other agent retained by such persons (collectively,
the "Inspectors"), all financial and other records, pertinent corporate
documents and properties of the Company and its subsidiaries (collectively,
"Records"), as shall be reasonably necessary to enable them to exercise their
due diligence responsibilities, and cause the Company's and its subsidiaries'
officers, directors and employees to supply all information and respond to all
inquiries reasonably requested by any such Inspector in connection with such
Registration Statement; and

                  (g) otherwise use commercially reasonable efforts to comply
with all applicable rules and regulations of the SEC, and make available to its
security holders, as soon as reasonably practicable, an earnings statement
covering a period of at least 12 months, beginning with the first month after
the effective date of the Registration Statement (as the term "effective date"
is defined in Rule 158(c) under the Securities Act), which earnings statement
shall satisfy the provisions of Section 1(a) of the Securities Act and Rule 158
thereunder.

                  SECTION 1.3  Registration Expenses. The Company shall pay for
all costs and expenses with respect to its compliance with its obligations in
connection with a registration hereunder, including, but not limited to: (i) all
registration and filing fees; (ii) fees and expenses of compliance with
securities or blue sky laws (including reasonable fees and disbursements of
counsel in connection with blue sky qualifications of the Registrable Shares);
(iii) printing expenses; (iv) internal expenses (including without limitation,
all salaries and expenses of its officers and employees performing legal or
accounting duties); (v) the fees and expenses incurred in connection with the
listing of the Registrable Shares on any national securities exchange, market
system or interdealer quotation system; (vi) the fees and disbursements of
counsel for the Company, and the Company's auditors (including the expenses of
any comfort letters or costs associated with the delivery by the Company's
auditors of a comfort letter or comfort letters); (vii) the fees and
disbursements of one legal counsel for all the selling stockholders
participating in such registration; (viii) the fees and expenses of any
registrar and transfer agent or any depository; (ix) the underwriting fees,
discounts and commissions applicable to any Common Stock sold for the account of
the Company; and (x) the cost of preparing all documentation in connection
therewith.

                  SECTION 1.4  Conversion of Other Securities. If the Executive
holds any options, rights, warrants or other securities that are offered with,
convertible

                                       3

<PAGE>   17
into or exercisable or exchangeable for any Registrable Shares, the Registrable
Shares underlying such options, rights, warrants or other securities shall be
eligible for registration pursuant to Section 1.1.

                  SECTION 1.5  Rule 144. If and for so long as the Company is
subject to the reporting requirements of the Securities Exchange Act of 1934, as
amended, (the "Exchange Act"), the Company shall take such measures and file
such information, documents and reports as shall be required by the SEC as a
condition to the availability of Rule 144 (or any successor provision) under the
Securities Act.

                  SECTION 1.6  Registration Statement Indemnification. (a) The
Company agrees to indemnify and hold harmless the Executive, each Transferee and
each person, if any, who controls any of the foregoing within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act
(collectively, the "Registration Indemnitee") from and against any and all
Losses arising out of or based upon any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement or
Prospectus, or arising out of or based upon any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, except insofar as such Losses arise out
of or are based upon any untrue statement or omission or alleged untrue
statement or omission which has been made therein or omitted therefrom in
reliance upon and in conformity with information relating to a Registration
Indemnitee furnished in writing to the Company by or on behalf of such
Registration Indemnitee expressly for use in the Registration Statement or
Prospectus.

                  (b) Each Registration Indemnitee agrees, severally and not
jointly, to indemnify and hold harmless the Company, its directors, its officers
who sign any Registration Statement, and any person who controls the Company
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act, to the same extent as the indemnity from the Company to each
Registration Indemnitee provided in Section 1.6(a), but only with respect to
information relating to such Registration Indemnitee furnishing in writing to
the Company by or on behalf of such Registration Indemnitee expressly for use in
the Registration Statement or Prospectus. If any Action shall be brought against
the Company, any of its directors, any such officer, or any such controlling
person based on any Registration Statement or Prospectus and in respect of which
indemnity may be sought against a Registration Indemnitee pursuant to this
Section 1.6(b), such Registration Indemnitee shall have the rights and duties
given to the Company by Sections 1.6 through 1.9 (except that if the Company
shall have assumed the defense thereof such Registration Indemnitee shall not be
required to do so, but may employ separate counsel therein and participate in
the defense thereof, but the fees and expenses of such counsel shall be at such
Registration Indemnitee's expense), and the Company, its directors, any such
officer, and any such controlling person shall have the rights and duties given
to the Registration Indemnitee by Sections 1.6 through 1.9.

                  SECTION 1.7  Contribution. (a) If the indemnification provided
for in this Exhibit A is unavailable to an indemnified party hereunder with
respect to any Losses referred to herein, then an indemnifying party, in lieu of
indemnifying such

                                       4
<PAGE>   18
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such Losses (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company, on the one
hand, and the applicable Registration Indemnitee, on the other hand, from the
offering of the securities covered by such Registration Statement and
Prospectus, or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company, on the one hand, and the applicable Registration
Indemnitee, on the other hand, in connection with the statements or omissions
that result in such Losses, as well as any other relevant equitable
considerations. The relative benefits received by the Company, on the one hand,
and the applicable Registration Indemnitee, on the other hand, shall be deemed
to be in the same proportion as the total net proceeds from the applicable
securities offering (before deducting expenses) received by the Company bear to
the total net proceeds from such offering (before deducting expenses) received
by such Registration Indemnitee. The relative fault of the Company, on the one
hand, and the applicable Registration Indemnitee, on the other hand, shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company, on the one hand,
or by such Registration Indemnitee, on the other hand, and the parties relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

                  (b) The Company and each Registration Indemnitee agree that it
would not be just and equitable if contribution pursuant to this Section 1.7
were determined by pro rata allocation or by any other method of allocation that
does not take account of the equitable considerations referred to in Section
1.7(a). The amount paid or payable by an indemnified party as a result of the
Losses referred to in Section 1.7(a) shall be deemed to include, subject to the
limitations set forth herein, any legal or other expenses reasonably incurred by
such party in connection with investigating any claim or defending any such
Action. Notwithstanding the provisions of this Section 1.7(b), a Registration
Indemnitee shall not be required to contribute any amount in excess of the
amount by which the proceeds to such Registration Indemnitee exceed the amount
of any damages that such Registration Indemnitee has otherwise been required to
pay by reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation, within the meaning
of Section 1(f) of the Securities Act, shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

                  SECTION 1.8  Procedure. If any Action shall be brought against
a Registration Indemnitee or any other person entitled to indemnification
(collectively with the Registration Indemnitee, the "Indemnitee") in respect of
which indemnity may be sought against the Company, such Indemnitee shall
promptly notify the Company, and the Company shall assume the defense thereof,
including the employment of counsel and payment of all fees and expenses. Such
Indemnitee shall have the right to employ separate counsel in any such action,
suit or proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such person unless (i) the
Company has agreed in writing to pay such fees and expenses, (ii) the

                                       5
<PAGE>   19
Company has failed to assume the defense and employ counsel, or (iii) the named
parties to an Action (including the impleaded parties) include both an
Indemnitee and the Company and such Indemnitee shall have been advised by its
counsel that representation of such indemnified party and the Company by the
same counsel would be inappropriate under applicable standards of professional
conduct (whether or not such representation by the same counsel has been
proposed) due to actual or potential differing interests between them (in which
case the Company shall not have the right to assume the defense of such Action
on behalf of such Indemnitee). The Company shall not be liable for any
settlement of any such Action affected without its written consent, which shall
not be unreasonably withheld or delayed, but if settled with such written
consent, or if there be a final judgment for the plaintiff in any such Action,
the Company agrees to indemnify and hold harmless each Indemnitee, to the extent
provided herein from and against any Losses by reason of such settlement or
judgment.

                  SECTION 1.9  Other Matters. (a) No indemnifying party shall
without the prior written consent of the indemnified party effect any settlement
of any pending or threatened Action in respect of which any indemnified party is
or could have been a party and indemnity could have been sought hereunder by
such indemnified party unless such settlement includes an unconditional release
of such indemnified party from all liability on claims that are the subject
matter of such Action, and does not include an admission of fault or culpability
on the part of any Registration Indemnitee.

                  (b) Any Losses for which an indemnified party is entitled to
