Re: Purchase Offer – GMAC Management LLC Class C Membership Interests

Dear Sanjay:

GMAC LLC hereby offers to purchase your profit interests granted under the GMAC
Management LLC Class C Membership Interests Plan (the “MPI Plan”). This is an
offer at current fair market value that you may accept or decline. If you accept
this Purchase Offer, all of your profit interests described below will be
purchased by GMAC and you will receive a cash payment within 30 days of
acceptance. Upon receipt of the Total Cash Payment, you will have no further
rights or interests under the MPI Plan. In order to accept this Purchase Offer
you must sign and return your acceptance within 30 days. You may only accept
this Purchase Offer for all of your profit interests described herein. You may
not accept on a partial basis.

By accepting this Purchase Offer, you agree that:

 

  1. At all times during your employment and within 24 months of the date of
payment, even if your employment terminates, you shall not at any time, directly
or indirectly, whether on behalf of yourself or any other person or entity,
engage in a Competitive Activity. “Competitive Activity” shall mean an activity
in which you engage directly or indirectly (whether as a principal, agent,
partner, member, employee, investor, owner, consultant, board member or
otherwise) that is in direct competition with GMAC LLC or any of its
subsidiaries or affiliates in any of the States within the United States, or
countries within the world, in which GMAC LLC or any of its subsidiaries or
affiliates conducts business with respect to a business in which GMAC LLC or any
of its subsidiaries or affiliates engaged or was preparing to engage during your
employment and on the date of your termination of employment; provided, however,
that an ownership interest of 1% or less in any publicly held company shall not
constitute a Competitive Activity; and further provided, however, that you may
be employed by or otherwise associated with a business or entity of which a
subsidiary, division, segment, unit, etc. is in direct competition with GMAC LLC
or any subsidiary or affiliate but as to which such subsidiary, division,
segment, unit, etc. you have no direct or indirect responsibilities or
involvement so long as you do not breach the covenant of confidentiality
contained herein; and

 

  2. At all times during your employment and within 24 months of the date of
payment, even if your employment terminates, you shall not at any time, directly
or indirectly, whether on behalf of yourself or any other person or entity
(i) solicit any client and/or customer of GMAC LLC or any subsidiary with
respect to a Competitive Activity or (ii) solicit or employ any employee of GMAC
LLC or any subsidiary, or any person who was an employee of GMAC LLC or any
subsidiary during the 60-day period immediately prior, for the purpose of
causing such employee to terminate his or her employment with GMAC LLC or such
subsidiary; and

 

  3. At all times during your employment and at all times thereafter, you shall
not disclose to anyone or make use of any trade secret or proprietary or
confidential information of GMAC LLC, including such trade secret or proprietary
or confidential information of any customer or client or other entity to which
GMAC LLC owes an obligation not to disclose such information, which you acquire
during your employment with GMAC LLC, including but not limited to records kept
in the ordinary course of business, except:

 

  (a) as such disclosure or use may be required or appropriate in connection
with your work as an employee of GMAC LLC; or

--------------------------------------------------------------------------------

  (b) when required to do so by a court of law, by any governmental agency
having supervisory authority over the business of GMAC LLC or by any
administrative or legislative body (including a committee thereof) with apparent
jurisdiction to order you to divulge, disclose or make accessible such
information; or

 

  (c) as to such confidential information that becomes generally known to the
public or trade without your violation of this paragraph 3; or

 

  (d) to your spouse, attorney, and/or your personal tax and financial advisors
as reasonably necessary or appropriate to advance your tax, financial and other
personal planning (each an “Exempt Person”), provided, however, that any
disclosure or use of any trade secret or proprietary or confidential information
of GMAC LLC by an Exempt Person shall be deemed to be a breach of this paragraph
3 by you; and

 

  4. At all times during your employment and within 24 months of the date of
payment, even if your employment terminates, you shall not make any statements
or express any views that disparage the business reputation or goodwill of GMAC
LLC and/or any of its subsidiaries, affiliates, investors, members, officers, or
employees.

If you materially violate any provision contained in paragraphs 1 through 4, you
will immediately repay GMAC LLC the entire Total Cash Payment and shall
reimburse GMAC LLC for its legal fees and costs associated with recovery of the
Total Cash Payment. Additionally, if you violate or threaten to violate any
provision contained in paragraphs 1 through 4, GMAC LLC shall not have an
adequate remedy at law. Accordingly, GMAC LLC shall be entitled to such
equitable and injunctive relief, without the posting of a bond, as may be
available to restrain you and any business, firm, partnership, individual,
corporation or entity participating in the breach or threatened breach from the
violation of the provisions of these paragraphs 1 through 4. Nothing in this
Purchase Offer shall be construed as prohibiting GMAC LLC from pursuing any
other remedies available at law or in equity for breach or threatened breach of
these paragraphs 1 through 4, including the recovery of damages. If GMAC LLC is
successful in enforcing its rights herein, you shall reimburse GMAC LLC for its
legal fees and costs associated with such enforcement action.

By accepting this Purchase Offer, you also agree that if you voluntarily
terminate your employment or if you are terminated for cause within one year of
the cash payment, you will repay GMAC LLC the entire Total Cash Payment. If you
voluntarily terminate or are terminated for cause after one year but within two
years of the cash payment, you will repay GMAC 50% of the Total Cash Payment.
Additionally, any severance payment you may receive during these time periods
will be reduced by these repayment obligations on a comparable after-tax basis.
A termination of employment for any other reason, such as death, disability, or
a sale of your business unit, will not trigger a repayment obligation.

Subject to the above terms and conditions, GMAC LLC hereby offers to purchase
the following profit interests at the purchase price described below:

 

12.00 bps series C-2

 

Total Cash Payment

   $ 696,000.00
