Exhibit 10.1

June 18, 2007

Mr. Peter N. Kellogg

Dear Peter:

On behalf of Merck & Co., Inc. (“Merck” or “the Company”), it is my pleasure to extend you an offer
of employment for the position of Executive Vice President & Chief Financial Officer. In this
position, you will report to me at Whitehouse Station. Our offer, which supersedes any written or
verbal offer previously extended to you by Merck, includes the following:

Total Compensation

Base Salary: You will be paid a gross monthly salary of $69,334, which equates to $832,008 on
an annual basis. Your salary will be reviewed annually. The date of your first merit
increase, if any, will be March 1, 2008.

Executive Incentive Plan: You will be eligible to participate in Merck’s Executive Incentive
Plan (EIP), subject to the terms of the plan. The target bonus for your position is 95% of
your annual base salary. The bonus is discretionary and the amount of the bonus, if any is
awarded, depends on individual performance, corporate performance, and an assessment of your
leadership.

Long-Term Incentive (LTI) Program: You will be eligible for consideration for annual grants of
stock-based incentives under the Merck & Co., Inc. Incentive Stock Plan. (The next annual
grant date is expected to be in February 2008.) In any given year, our incentives may include
stock options, performance share units (PSUs), restricted stock units (RSUs) or any combination
thereof, with the number and proportion of shares covered by such incentives determined by the
Compensation and Benefits Committee. For illustrative purposes, a grant for a position at your
job level may be in the range of 74,000 stock options, 14,000 PSUs and 14,000 RSUs. Currently,
annual grants of Merck stock options vest in equal installments over three years; PSUs have a
three-year performance period; and RSUs have a three-year restriction period.

Distribution of shares in connection with both PSUs and RSUs is dependent on continued
employment with the Company; additionally, the level of payout associated with PSUs is
contingent on Company performance. Please note that terms and conditions of any future grants
may change from time to time. The specific terms and conditions of your grants will be
provided at the time the grants are made to you. Based on your job level within the Company,
you will be covered by Merck’s stock ownership guidelines. The guidelines are intended to
reinforce our philosophy concerning “ownership” and, in a concrete way, quantify our
expectations concerning ownership of Merck stock. Based on your job level within the Company,
the guidelines provide that you should acquire Merck stock, over time, equal in value to five
times your annual base salary. Importantly, the LTI program – and retention of shares earned
in connection therewith – is intended to facilitate the acquisition of shares. Also, there is
currently no time frame under which you will be required to achieve the multiple of salary.

Deferral Program: Based on the level of your job within the Company, you will have the
opportunity within the first 30 calendar days of the first day of your employment (provided
that your first day is no later than December 1, 2007) to elect to defer (1) a portion of your
base salary and/or (2) all or part of the EIP bonus you will receive for Performance Year 2007.
This 30-day period represents your only opportunity to elect a deferral for compensation
earned in 2007. Information about the Deferral Program and instructions pertaining to this
election will be contained in your new-hire materials when you join the Company. If you do not
receive Deferral Program information and instructions, please contact the Merck Benefits Center
at 800-66MERCK (800-666-3725).

Sign-On Incentives

Sign-On Bonus. You will be paid a one-time sign-on bonus of $150,000 before taxes, which you
will receive in your first regularly scheduled paycheck following your start date. The sign-on
bonus will be paid to you in a lump sum. However, it is conditioned upon your not voluntarily
terminating your continued employment with Merck & Co., Inc. or its subsidiaries for 24 months.
If your employment is voluntarily terminated by you within twenty-four months of your start
date, upon such termination you will be required to repay a pro-rata portion of the sign-on
bonus based on months of completed service.

Stock Option Grant. The Compensation and Benefits Committee has approved your receiving a
stock option to purchase 175,000 shares of Merck common stock at a fixed price per share that
is set by the Company on the grant date. Grants to new hires are currently scheduled to be
made in early February, May, August and November; the date of your grant will be the quarterly
grant date immediately following your start date. Subject to its terms, this stock option
grant will vest in equal installments on the first, second, third, fourth, and fifth
anniversaries of the grant date and expire on the day before the tenth anniversary of the grant
date. A summary of terms and conditions associated with this stock option grant will be
provided to you shortly after the grant is made. Vested options terminate within three months,
and unvested options expire immediately, if you voluntarily terminate your employment. If the
Company terminates your employment for “gross misconduct” (as defined below), all options, both
vested and nonvested, expire immediately. If your employment terminates for reasons other than
your voluntary termination or termination by Merck for gross misconduct, all unvested
installments under this grant will vest immediately on the last day of your employment, become
exercisable according to their original schedule and remain exercisable until the day before
the tenth anniversary of their grant. For purposes of this letter, “gross misconduct” means:
unauthorized disclosure of information known to be proprietary or confidential; embezzlement,
theft or other misappropriation of Company assets; falsification of records or reports;
deliberate or reckless action that causes actual or potential injury or loss to the Company or
employees of the Company; failure to carry out assigned duties after notice in writing that
such failure, if not corrected, will result in termination of employment; or an illegal act on
Company property or in representing the Company.

Restricted Stock Unit Grant. The Compensation and Benefits Committee has approved your
receiving a grant of 80,000 RSUs to be made on the same date as the stock option grant
referenced in the preceding paragraph. Subject to its terms, this RSU grant will vest
according to the following schedule:

	 	1.	 	40,000 RSUs (or 50% of the grant) will 100% vest on the third anniversary of
the grant date and

	 	2.	 	40,000 RSUs (or 50% of the grant) will 100% vest on the sixth anniversary of
the grant date.

	 	3.	 	Notwithstanding the above, these RSUs will vest immediately on the last day
of your employment if your employment with Merck terminates for reasons other than
your voluntary termination or termination by Merck for gross misconduct. Such RSUs
will nonetheless continue to be payable on the third or sixth anniversary of their
grant as provided above.

page 3

Dividend equivalents will be paid on the RSU grant during its restricted period. A summary
of terms and conditions associated with this RSU grant will be provided to you shortly
after the grant is made.

Benefits

Flexible Benefits Program: As a salaried employee of Merck, you will be eligible to
participate in the Flexible Benefits Program, which allows you to choose among various options
for medical, dental, vision, employee term life insurance, accidental death and dismemberment
insurance, survivors’ income benefits, dependent life insurance, long-term disability, health
care reimbursement, dependent care reimbursement account, and long-term care plans. For most
benefits, participation begins on your date of hire. A Merck Benefits New Hire Kit will be
mailed within 2 weeks of your hire date to your home address from Fidelity Investments, service
provider for both the Flexible Benefits Program and the Merck Savings Plan. This kit provides
important information and instructions for enrolling in your Merck benefits. You will have 30
days from the date Fidelity mails your benefit information, to enroll in the benefits available
to you under the Flexible Benefits Program. If you do not enroll by that date, you will be
automatically enrolled for a minimal level of coverage for yourself only under certain of the
available benefit coverages.

Please note that general information about Merck’s benefits is also available through the Merck
Benefits Internet website at www.merck.com/benefits.

Retirement Plan: You will participate in the Merck Retirement Plan for Salaried Employees (a
“qualified” plan) and the Supplemental Retirement Plan (a “non-qualified” plan). The
supplemental plan provides payment of that portion of an employee’s regular benefit that is in
excess of the portion that can be paid under the qualified plan, as stipulated by the Internal
Revenue Code. The supplemental plan is unfunded and may be terminated at any time for any
reason. Participation in the retirement plans will begin the earlier of the July 1 or January
1 on or immediately following your start date.

Please note that Merck has an executive retirement policy that applies to employees at your job
level within the Company. Consistent with the limited exemption provided for in the Age
Discrimination in Employment Act (“ADEA”), it is Merck’s policy that employees who are “bona
fide executives” or “high policymakers” within the meaning of the ADEA and who meet the other
necessary criteria set forth in the ADEA, will be required to retire on the first day of the
month following their 65th birthday.

Savings Plan: You will be eligible to participate in the Employee Savings and Security Plan for
Salaried Employees. Currently, the savings plan includes pre- and after-tax savings options
and Merck matching contributions of 75 cents for each dollar saved up to 6% of base pay per pay
period (up to the IRS limit). More information about the Savings Plan will be provided to you
at a later date.

Financial Planning: Based on your job level within the Company, you will be eligible to
participate, on a voluntary basis, in Merck’s executive financial planning program. Under the
program, the Company will reimburse you for payments that you make to one or more of our
selected financial planners. Reimbursement will be up to $12,500 in the first calendar year of
your participation and up to $10,000 per calendar year thereafter. Reimbursement will be made
by paycheck, less applicable tax withholding, and will be included in your W-2 income. You
will be provided more information about the program shortly after joining the Company.

page 4

Vacation and Paid Holiday Policy: Your vacation benefit will be 27 days annually, in
accordance with Merck policy. In addition to your vacation benefit, Merck policy currently
provides 13 paid holidays; 9 of these holidays are predetermined holidays and 4 are personal
floating holidays. Personal floating holidays are selected at your discretion and are subject
to supervisory approval. The number of vacation days and personal floating holidays for which
you are eligible in your first calendar year of employment (2007) will be pro-rated, based upon
your date of hire.

Relocation

Relocation. As part of our standard relocation benefits, the Company will reimburse you for
certain reasonable expenses associated with your move in accordance with Merck’s Relocation
Policy.

Severance

In the event that, during the period beginning on your date of hire and ending two years after
the appointment of a successor CEO to Richard T. Clark, Merck terminates your employment for a
reason other than gross misconduct, Merck will pay to you a lump sum in the amount of eighteen
months’ salary, subject to appropriate tax withholding, upon such termination of your
employment, provided that upon the termination of your Merck employment you must timely sign
and comply with noncompete, nonsolicitation and nondisclosure covenants and a waiver and
release of claims in a format prescribed by Merck. This severance payment is in lieu of any
other severance or separation pay that you might be entitled to under any applicable Merck
policy or policies.

If at the time your employment terminates you are a “Specified Employee” as defined in Treas.
Reg. Sec. 1.409A-1(i) or any successor thereto, (which in general includes the top 50 employees
of a company ranked by compensation), to the extent required by Section 409A of the Internal
Revenue Code of 1986, as amended, the severance payment described above will be made in a lump
sum, without interest, as soon as administratively feasible on the first day of the sixth month
after the termination of your employment.

The compensation and benefits described in this letter are provided under and subject to the terms
and conditions of the applicable Merck plans, programs and policies. Nothing in this letter in any
way limits Merck’s right to amend or terminate those plans, programs or policies.

This offer is contingent upon your successful completion of a pre-placement drug screen,
satisfactory verification of your employment, education, criminal check and background check
results and proof of your eligibility to work in the United States (see attached List of Acceptable
Documents, which you are required to bring with you on your first day of work). Your employment at
Merck & Co., Inc. is at-will and additionally will be subject to Merck’s terms and conditions of
employment, which will be provided to you when this offer is confirmed. We advise you not to
alter your current employment status until we confirm the contingent offer.

This Second Amendment and Consent, dated as of June 28, 2007 (this
“Amendment”), to Credit Agreement, dated as of October 26, 2005 (as the same may
be amended, restated, supplemented or otherwise modified from time to time, the “Credit

W i t n e s s e t h:

Whereas, Borrower and Holdings desire to cause a merger of Holdings into Alpha
Natural Resources, Inc. (“ANR, Inc.”), with ANR, Inc. as the surviving corporation (the

Whereas, the Merger would require certain amendments to the Loan Documents in order
to be permitted thereunder, and the Borrower and Holdings have requested such amendments be made as

WHEREAS, Borrower and Holdings have requested that the Lenders and Administrative Agent amend
certain terms of the provisions of the Credit Agreement to permit the Merger and to address certain
