     2. Transfer of Units.

     (a) Transferor hereby Transfers ____ Units to Transferee, and Transferee
hereby accepts such Units, in each case subject to forfeiture as provided in
Section 4 hereof and the other terms and conditions of this Agreement.

     (b) Transferee will be entered into the records of the Company as the
holder of the Units Transferred pursuant to this Agreement, and Transferee
shall be subject to the provisions and restrictions set forth in the LLC
Agreement.

     3. Effective Date of Agreement.

     This Agreement is effective as of the date first above written. As
required by the LLC Agreement, the Managing Member of the Company has approved
this Agreement and the Transfer of Units pursuant hereto as evidenced by its
signature on the signature page hereto.

     4. Restrictions and Conditions; Forfeiture.

     (a) The Units are subject to forfeiture back to Transferor during such
periods, in such percentage amounts and upon the occurrence of such conditions
and events as are indicated on Schedule I attached hereto.

     (b) Except as provided in Section 4(a), Transferee shall have, in respect
of the Units, all of the rights of a Member of the Company, including the right
to vote the Units and the right to receive and retain any cash distributions in
respect of such Units, until such time (if ever) as such Units are forfeited
back to the Company. Transferee shall not be required to return to Transferor
any distributions received in respect of subsequently forfeited Units.

     (c) Upon forfeiture of Units held by Transferee back to Transferor
pursuant to Section 4(a), Transferee shall (i) cease to be a Member of the
Company and shall have no further rights to distributions or allocations of
Profits and Losses of the Company, if as a result of such forfeiture no Units
continue to be held by Transferee, or (ii) continue to be a Member of the
Company but shall have no further rights to distributions or allocations of
Profits and Losses of the Company in respect of such forfeited Units, if
Transferee continues to hold other Units. Any forfeiture of Units shall,
without any further action by Managing Member, Transferee, the Company or any
other Person, result in an automatic Transfer of the Units so forfeited
hereunder from Transferee to Transferor.

     5. Section 83(b) Tax Election.

Transferee shall execute three copies of a Section 83(b) Tax Election Form,

received. Transferee shall promptly file one copy of the Section 83(b) Tax
Election Form with the IRS and deliver one copy of the Section 83(b) Tax
Election Form to the Special Member. Upon receipt of such duly executed form,
the Special Member shall cause such copy to be filed in the records maintained
by the Company. Notwithstanding anything contained in this Agreement to the
contrary, Transferee's execution and delivery of the Section 83(b) Tax Election
Form shall be a condition precedent to Transferor's obligation as may otherwise
be provided hereunder to Transfer Units to Transferee, and the failure of
Transferee to satisfy such requirement with respect to the Units shall cause
such Units to be forfeited in accordance with Section 4 hereof.

     6. Nontransferability of Unvested Units.

administer this Agreement and any other instrument or agreements relating to
this Agreement. The Managing Member's actions in this regard shall be final,
conclusive and binding upon all persons, including without limitation
Transferee and Transferee's beneficiaries.

     (b) The failure of Transferor, Transferee or the Company to insist upon
strict compliance with any provision of this Agreement, or to assert any right
Transferor, Transferee or the Company, respectively, may have under this
Agreement, shall not be deemed to be a waiver of such provision or right or any
other provision or right of this Agreement or the LLC Agreement.

     (c) Nothing in this Agreement shall confer on Transferee any right to
continue in the employ or other service of Insignia or interfere in any way
with the right of Insignia to terminate Transferee's employment or other

                                   SCHEDULE I

                             VESTING AND FORFEITURE

VESTING

Initially, 98% of the Units are subject to forfeiture back to Transferor under
the circumstances hereinafter described (i.e., such Units are "Unvested"), and
2% of the Units are not subject to forfeiture back to Transferor (i.e., such
Units are "Vested").

Subject to the following provision providing for accelerated time-based vesting
of Units under certain circumstances, until the earlier of (i) such time as all
of the Units become Vested or (ii) such time as Unvested Units are forfeited
back to Transferor pursuant to this Agreement, on the last day of each calendar
month following the date of this Agreement, the percentage of Units that is
Unvested (and thus subject to forfeiture back to Transferor) shall be decreased
by 2% (in absolute terms), and the percentage of Units that is Vested shall be
increased by 2% (in absolute terms).

If Transferee's employment (or other service, if applicable) with Insignia is
terminated by Insignia for any reason other than Cause, then all of the Units
that are Unvested at such time shall immediately and automatically become
Vested.

FORFEITURE

If Transferee's employment (or other service, if applicable) with Transferor is
terminated (i) by Insignia for Cause, (ii) by Transferee for any reason or
(iii) as a result of the death or disability of Transferee, then all Units that
are Unvested at such time shall thereupon, and with no further action, be
forfeited by Transferee back to Transferor.

EMPLOYMENT AGREEMENT CONTROLS

If at any given time of determination Transferee is a party to a written
employment agreement with Insignia (or a subsidiary of Insignia) containing
terms that are more favorable to Transferee than those set forth in this
Schedule I, then the more favorable terms of such employment agreement shall
control.

                                   SCHEDULE I

                             VESTING AND FORFEITURE

VESTING

Initially, 96% of the Class A Units and 96% of the Class B Units are subject to
forfeiture back to Transferor under the circumstances hereinafter described
(i.e., such Units are "Unvested"), and 4% of the Class A Units and 4% of the
Class B Units are not subject to forfeiture back to Transferor (i.e., such
Units are "Vested").

Subject to the following provision providing for accelerated time-based vesting
of Units under certain circumstances, until the earlier of (i) such time as all
of the Class A Units and Class B Units become Vested or (ii) such time as
Unvested Class A Units and Unvested Class B Units are forfeited back to
Transferor pursuant to this Agreement, on the last day of each calendar month
following the date of this Agreement, the percentages of Class A Units and
Class B Units that are Unvested (and thus subject to forfeiture back to
Transferor) shall be decreased by 2% (in absolute terms), and the percentages
of Class A Units and Class B that are Vested shall be increased by 2% (in
absolute terms).

If Transferee's employment (or other service, if applicable) with Insignia is
terminated by Insignia for any reason other than Cause, then all of the Class A
Units and Class B Units that are Unvested at such time shall immediately and
automatically become Vested.

FORFEITURE

If Transferee's employment (or other service, if applicable) with Transferor is
terminated (i) by Insignia for Cause, (ii) by Transferee for any reason or
(iii) as a result of the death or disability of Transferee, then all Class A
Units and all Class B Units that are Unvested at such time shall thereupon, and
with no further action, be forfeited by Transferee back to Transferor.

EMPLOYMENT AGREEMENT CONTROLS

If at any given time of determination Transferee is a party to a written
employment agreement with Insignia (or a subsidiary of Insignia) containing
terms that are more favorable to Transferee than those set forth in this
Schedule I, then the more favorable terms of such employment agreement shall
control.
