Exhibit 10.1

                             PARTICIPATION AGREEMENT
                        High Island Area, Block 138 (S/2)

     This Participation Agreement ("Agreement") is made and entered into
effective as of the 1st day of March, 2008 by and between LLOG Exploration
Offshore, Inc. ("LLOG"), and Ridgewood Energy Corporation ("Ridgewood"). LLOG
and Ridgewood are sometimes hereafter referred to collectively as "Parties" and
individually as "Party."

                                    RECITALS

     WHEREAS, LLOG has identified a prospect on the S/2 of High Island Area,
Block 138 ("Block") and has acquired Oil & Gas Lease OCS-G 31040 ("Lease") from
the United States of America which Lease is further defined on the attached
Exhibit "A"; and,

     WHEREAS, LLOG plans to drill the OCS-G 31040 #1 Well ("Initial Test Well"
or "ITW") to a depth of 17,031 feet MD (15,400 feet TVD) or to a depth
sufficient to test the Marg A-2 Sand (the top of which was seen in the OCS-G
27505 #1 ST1 well at 14,976 feet), whichever is the lesser depth ("Objective
Depth"). The ITW shall be drilled at a surface location of 7,635' FSL and 6,757'
FWL of the Block, and of bottom hole location of 3,450' FSL and 6,232' FEL of
the Block; and,

     WHEREAS, LLOG has offered to Ridgewood the opportunity to participate in
the drilling of the ITW, and Ridgewood has accepted LLOG's offer and has agreed
to bear fifty percent (50%) of the drilling costs ("Participating Interest") of
the ITW in order to earn a twenty-five percent (25%) record title interest in
the ITW and Lease.

     NOW, THEREFORE, in consideration of the mutual covenants and agreement
herein contained, the Parties hereto agree as follows:

1.   REIMBURSABLE LAND COSTS
     -----------------------

Within fifteen (15) days of execution of this Agreement, Ridgewood shall
reimburse LLOG $2,219,643.75 for its 25% share of the "Sunk Land Costs". The
Sunk Land Costs for the Lease are $8,635,575 in bonus costs, $18,000 in rentals,
$25,000 for a license on the Shallow Hazard Data and $200,000 for G&G and
miscellaneous land costs.

2.   ASSIGNMENT OF RECORD TITLE
     --------------------------

Within fifteen (15) days from receipt of the Sunk Land Costs, LLOG shall execute
and deliver to Ridgewood an Assignment of Record Title Interest delivering to
Ridgewood a 25% of 6/6ths Record Title Interest in the Lease. The Assignment
shall be without warranty of title, either express or implied, except by,
through and under LLOG, but not otherwise. Additionally, such Assignment shall
be subject to the approval of the authorized officer of the U.S. Mineral
Management Service. The Assignment shall be prepared with an attached Exhibit
"A" thereto, with said Exhibit "A" being a mutually acceptable assignment form
which can be executed by the parties and recorded in the appropriate
County/Parish, as applicable. The Assignment shall be further subject to a 2.5%
overriding royalty interest in favor of Blue Streak Exploration which shall
deliver to Ridgewood the net revenue interest set forth on Exhibit "A"

<PAGE>

attributable to its 25% record title interest. LLOG and Ridgewood agree to
execute any necessary documents and take all other actions reasonably necessary,
if any, to assist in the MMS approval process.

3.   INITIAL TEST WELL
     -----------------

Ridgewood agrees to assume their Participating Interest in the costs to drill
and evaluate the ITW to "Casing Point". The Authority for Expenditure ("AFE") to
drill the ITW is Attached hereto as Exhibit "B". Concurrent with the execution
of this Agreement, the parties agree to approve and execute the formal AFE. As
used in this Agreement, "Casing Point" shall mean that point in time when the
ITW has been drilled to Objective Depth and after all logs, cores and other
approved tests contemplated in the AFE have been conducted which are necessary
to reach the decision for further operations in the ITW, and the results thereof
have been furnished to all of the Parties, along with Operator's recommendation.
It is understood that Casing Point shall include plugging and abandonment costs
in the event the ITW is not completed for production or temporarily abandoned in
contemplation of further operations.

Ridgewood will pay its Participating Interest in the ITW until such time as the
ITW reaches Casing Point or the actual costs to drill and evaluate the ITW
reaches 110% of the AFE ("Promote Cap"), whichever occurs first. Thereafter,
Ridgewood's costs in the ITW shall be based on a twenty-five percent (25%)
working interest.

LLOG, as Operator, shall have the right to require Ridgewood to pay advances in
accordance with the terms of the COPAS attached to the Offshore Operating
Agreement described herein.

4.   SUBSTITUTE WELL
     ---------------

If during the drilling of the ITW, LLOG encounters impenetrable substances or
conditions, including loss of hole due to mechanical difficulties, which in the
opinion of a reasonably prudent operator under the same or similar conditions,
would render further drilling impracticable or hazardous and the condition
prevents further drilling of the ITW, LLOG may commence a "Substitute Well",
provided the drilling operations on such Substitute Well are commenced within
one hundred eighty (180) days after release of the drilling rig from the ITW.
However, with respect to such Substitute Well, the Promote Cap applicable to the
original AFE shall not be adjusted upward in the event the cumulative costs of
the ITW and the Substitute Well, as the case may be, exceed the original Promote
Cap.

5.   OFFSHORE OPERATING AGREEMENT
     ----------------------------

The ITW shall be drilled in accordance with the February 15, 2008 Offshore
Operating Agreement ("OOA") which is sent in conjunction with, and as a
condition to this Agreement. Contemporaneously with the execution of this
Agreement, Ridgewood agrees to execute the OOA and return two (2) signature
pages to LLOG. Castex Offshore, LLC ("Castex") is also a party to the OOA and
LLOG shall furnish Ridgewood copies of Castex's signature page. All operations
on the Initial Test Well and any and all subsequent operations on the Lease
shall be conducted in accordance with the terms and provisions of the OOA.

                                       2
<PAGE>

If there are any conflicts between this Agreement and the OOA, the terms and
provisions of this Agreement shall prevail and govern.

6.   INFORMATION REQUIREMENTS
     ------------------------

During the drilling of the ITW, LLOG shall deliver to Ridgewood the information
shown on the attached Exhibit "C".

7.   TIMELY OPERATIONS
     -----------------

LLOG will diligently and timely move forward in securing a rig necessary to
drill the ITW as soon as possible. LLOG is committed to having commenced
operations by April 30, 2008, subject to rig availability and obtaining the
required permits. LLOG shall not be liable to Ridgewood or suffer any penalties
for failure to spud the ITW by April 30, 2008. Notwithstanding anything herein
to the contrary, should LLOG not spud the ITW by April 30, 2008, Ridgewood shall
have the sole option to elect to terminate this Agreement and its participation
commitment hereunder ipso facto. If Ridgewood so elects to terminate this
Agreement, it shall not be liable to LLOG or suffer any penalties thereto for
such termination, and all commitments and obligations will cease upon such
notice to terminate. Upon such termination, any assignments of interest into
Ridgewood will be reassigned to LLOG and any and all Sunk Land Costs paid by
Ridgewood to LLOG will be refunded back to Ridgewood via wire transfer
simultaneously with such reassignment of interest to LLOG.

8.   TERM
     ----

This Agreement shall terminate at such time as 1.) the ITW has reached Objective
Depth, and 2.) the Assignment provided for in Article 4 has been filed and
accepted by the Minerals Management Service. Thereafter all operations to be
conducted for the joint benefit of the Parties shall be subject to the OOA.

9.   MISCELLANEOUS

Mr. Andrew B. Szafran

Dear Andrew:

I am pleased to present this offer of employment to join APAC Customer Services, Inc.
(“APAC” or the “Company”) as Senior Vice President, Chief Financial Officer reporting to me. The
following terms will apply:

	 	1.	 	Your start date will be May 14, 2008.

	 	2.	 	Your starting base salary will be $300,000.00 on an annualized basis, payable
bi-weekly. (This “base salary” is stated for convenience only and is not intended as an
annual contract of employment.) Your base salary will be reviewed each year at the time
when increases for executives of APAC are considered. At the present time that occurs on or
about April 1 of each year.

	 	3.	 	You will be a participant in an incentive compensation plan as described in the
attached document titled “Management Incentive Plan – Annual Corporate Plan 2008”. Your
target for this plan will be 50% of base pay with a maximum payout of 80% of base pay.

	 	4.	 	You will be entitled to paid vacation of four (4) weeks and will also be entitled to
participate in all employee benefit plans and programs extended to employees at the
executive level.

	 	5.	 	Based on your official start date, you will be granted options to purchase 450,000
shares of APAC common stock under the terms of the APAC Customer Services, Inc. Amended and
Restated 2005 Incentive Stock Plan at an exercise price equal to the closing price of
APAC’s common stock on that date. These options will vest at the rate of 20% per year
during the first five years of your employment and shall otherwise have the terms and
conditions set forth in the Employee Stock Option Agreement attached hereto.

	 	6.	 	Upon joining the company, you will receive an Employment Security Agreement, which
outlines additional cash compensation protection in the event of “Change in Control” of the
Company (draft copy enclosed).

	 	7.	 	As a condition of employment, you will sign an “Agreement Protecting Company
Interests”, a copy of which is enclosed.

	 	8.	 	Except for (1.) your termination of employment in connection with a “Change in Control”
as defined in the Employment Security Agreement referenced above, or (2.) your termination
of employment by APAC “for cause” (Defined as “(i) gross misconduct or gross negligence in
the performance of your employment duties; (ii) willful disobedience by you of the lawful
directions received from the Company or from the person to whom you directly report or of
established policies of the Company; or (iii) commission by you of a crime involving fraud
or moral turpitude that can reasonably be expected to have an adverse effect on the
business, reputation or financial situation of the Company”), or (3.) your termination as a
result of your resignation from employment with the Company other than for “Agreed Reason,”
and provided you sign a then-current Waiver & Release Agreement, APAC will pay you
severance equal to three-fours (3/4) of the monthly amount of your then-current Base Salary
during each of the following twelve (12) months following such termination.

Resignation for “Agreed Reason” shall mean a resignation by you prior to any Change in
Control if, after giving notice to the Company within thirty days following the initial
existence of one of the following conditions and providing a thirty day opportunity for
the Company to cure the condition:

	 	 	 	 	 
	(1)

	 	 
	 	without your written consent, (i) your duties and responsibilities

are materially reduced or diminished from those in effect on your

commencement of employment, or (ii) you no longer report to the

Chief Executive Officer of the Company, and instead are required to

report to a supervisor with materially diminished authority, duties

or responsibilities compared to that of the Chief Executive Officer

of the Company, or
	(2)

	 	 
	 	your base salary is reduced and not in accordance with a

compensation reduction applicable to all senior executives’

salaries generally, or
	(3)

	 	 
	 	any other material breach of the terms of this agreement or the

terms of your employment in general.

Severance payments will be made in accordance with either this agreement or the
prevailing change of control agreement, whichever is more advantageous to you; but in no
event will severance payments be made under both agreements. Such payments will be made
on APAC’s customary payroll dates in installment equal to three-fours (3/4) of your
regular biweekly salary, less all applicable withholding taxes.

Notwithstanding the foregoing, if you are deemed at the time of your separation from
service to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the
Internal Revenue Code (the “Code”), to the extent delayed commencement of any portion of
the severance payments to which you are entitled under this agreement is required in
order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code,
such portion of your severance payments will not be provided to you prior to the earlier
of (1) expiration of the six-month period measured from the date of your “separation
from service” with the Company (as such term is defined in Treasury Regulations issued
under Section 409A of the Code) or (2) your death.  Upon expiration of the applicable
Code Section 409A(a)(2)(B)(i) deferral period, all payments deferred pursuant to this
paragraph shall be paid in a lump sum to you, and any remaining payments due shall be
paid as otherwise provided herein.

	 	9.	 	This offer is extended contingent upon receipt of a completed Application for
Employment, satisfactory references, and adequate results of a background investigation.

	 	10.	 	You hereby represent and warrant that you are not subject to any covenants, agreements
of restrictions, including, without limitation, any covenants, agreements or restrictions
arising out of your prior employment or independent contractor relationships, which would
be breached or violated by your acceptance of this offer of employment or by your
performance of your duties. You acknowledge that it is APAC’s express policy to abstain
from the use or disclosure of the trade secrets and proprietary information of third
parties, and you hereby expressly covenant that you will not use or disclose trade secrets
or proprietary information of third parties while working at APAC.

Andrew, we are excited about your joining APAC. If you have any questions please don’t hesitate to
contact me.

Sincerely,

APAC CUSTOMER SERVICES, INC.
