December 19, 2006 (the “ Agreement ”), by and among Aleris
International, Inc. (the “ Company ”), Aurora Acquisition
Holdings, Inc. (the “ Parent ”) and Sean Stack (the
“ Executive ”).
  WHEREAS, the Company desires that the Executive continue to serve the Company as the Company’s Executive Vice President and President, Europe , on the terms and conditions set forth
herein.
  NOW, THEREFORE, in consideration of the premises and
mutual covenants herein and for other good and valuable consideration, the parties agree as follows:
  1.
Employment, Duties and Agreements.
  (a) The Company hereby agrees to continue to employ the Executive as its Executive Vice President and President, Europe , and the Executive hereby accepts such position
and agrees to continue to serve the Company in such capacity during the employment period fixed by Section 3 hereof (the “ Employment Period ”). The Executive shall have such duties and responsibilities as are consistent with the Executive’s position and as may be assigned by the Company from time to time.
During the Employment Period, the Executive shall be subject to, and shall act in accordance with, all reasonable instructions and directions and all applicable policies and rules of the Company.
  (b) During the Employment Period, excluding any periods of vacation and sick leave to which the Executive is entitled, the Executive shall devote his full working time, energy and
attention to the performance of his duties and responsibilities hereunder and shall faithfully and diligently endeavor to promote the business and best interests of the Company. During the Employment Period, the Executive may not, without the prior
written consent of the Company, directly or indirectly, operate, participate in the management, operations or control of, or act as an executive, officer, consultant, agent or representative of, any type of business or service (other than as an
executive of the Company). It shall not, however, be a violation of the foregoing provisions of this Section 1(b) for the Executive to (i) subject to the approval of the Board, serve as an officer or director or otherwise participate in
non-profit, educational, welfare, social, religious and civil organizations, or (ii) manage his personal, financial and legal affairs, so long as any such activities in (i) and (ii) do not interfere with the performance of his duties and
responsibilities to the Company as provided hereunder.
  (c) In connection with the Executive’s employment by the Company under this Agreement, the Executive
shall be based at the principal executive offices of the Company, currently located in Beachwood, Ohio, except for such travel as the performance of the Executive’s duties in the business of the Company may require; provided, however, that the
Executive agrees that the temporary assignment of the Executive to the Company’s current offices in the greater Zurich, Switzerland area, or such other location in the greater Zurich, Switzerland area to which such offices may be relocated,
shall not be an event constituting Good Reason under the Severance Agreement (defined below) or this Agreement.
  (d) The Severance Agreement, dated as of August 30, 2005, by and between the Company and the Executive (the
“ Severance Agreement ”) is expressly assumed hereby as
contemplated in section 10(b) thereof. The Executive hereby acknowledges and agrees that the foregoing assumption by the Company of the Severance Agreement, and the entrance by the Company into this Agreement, is in full satisfaction of the
Company’s obligations under section 10(b) of the Severance Agreement to assume, by written instrument delivered to the Executive, all of the obligations under the Severance Agreement, and that the Executive will not have the right to terminate
his employment for “Good Reason” as defined in the Severance Agreement under Item (5) of such definition as a result of the merger of Aurora Acquisition Merger Sub, Inc. (“ Merger Sub ”) with and into the Company, as contemplated by the Agreement and Plan
of Merger, dated August 7, 2006, by and among the Parent, Merger Sub and the Company (the “ Merger Agreement ”). The Severance Agreement shall remain in full force and effect through the second anniversary of the Effective Date. Upon the second anniversary of the Effective Date,
and not before, the Severance Agreement shall be terminated and of no further force or effect, provided, however, that the Severance Agreement shall continue in effect with respect to all rights and obligations that have accrued thereunder prior to
such termination until such rights and obligations have been fully satisfied or otherwise expire. Notwithstanding anything to the contrary in the Severance Agreement (including, without limitation, section 8 thereof), this Agreement shall constitute
notice pursuant to section 8 of the Severance Agreement, to the extent necessary, that the Severance Agreement shall terminate on the second anniversary of the Effective Date. During the period prior to the second anniversary of the Effective Date,
in the event of a conflict between the terms of the Severance Agreement and this Agreement, the terms of the Severance Agreement shall govern.
  2.
Compensation.
  (a) As compensation for the agreements made by the Executive herein and the performance by the Executive of
his obligations hereunder, during the Employment Period, the Company shall pay the Executive, pursuant to the Company’s normal and customary payroll procedures, a base salary at the rate of $325,000 per annum, (the “ Base Salary ”). During the Employment Term, the Base Salary will be reviewed
annually and is subject to adjustment at the discretion of the Board of Directors of the Company (the “ Board ”), but in no event shall the Company pay the Executive a Base Salary less than that set forth above during the Employment Term.
  (b) In addition to the Base Salary, during the Employment Period, but beginning for the fiscal year ending December 31, 2007, the Executive shall be eligible to participate in the
annual incentive plan (the “ AIP ”) established and approved by
the Board and, pursuant to the AIP, the Executive may earn an annual bonus (the “ Annual Bonus ”) in each fiscal year during the Employment Period, with a target Annual Bonus of 75% of Base Salary up to a maximum of 150% of Base Salary, based on the achievement of
annual performance objectives as set forth in the AIP, subject to the Executive’s employment with the Company through the applicable payment date for any such Annual Bonus (unless otherwise provided herein or in the Severance Agreement). For
the fiscal year ending December 31, 2006, the Company shall pay the Executive all bonuses and other incentives to which the Executive is entitled pursuant to and in accordance with the Company’s incentive plans in effect as of the Effective
Date.
  (c) As soon as practicable after the Effective Date (as defined below), the Company will grant the Executive a
number of options (the “ Options ”) to purchase shares of the
Parent (the “ Shares ”) at an exercise price per Share equal to
the price per Share paid by TPG (as defined below). The specific terms and conditions governing all aspects of the Options shall be provided in separate grant agreements and any relevant plan documents (collectively, the “ Option Agreements ”). The Options shall be comprised of the following two
tranches: (1) 60% of the Options (the “ Time-Based Options ”)
will vest and become exercisable in equal annual installments of 20% over a five-year period, subject to the Executive’s continued employment with the Company through the applicable vesting date and (2) 40% of the stock options (the
“ Performance-Based Options ”) will vest and become exercisable
only upon the achievement by the Company of the following performance targets, in each case, subject to the Executive’s continued employment with the Company through the applicable vesting date: (A) 50% of the Performance-Based Options will
vest upon the occurrence of any liquidity event in connection with which TPG Partners IV, L.P. and TPG Partners V, L.P. (together, " TPG ") realize a multiple of money (“ MoM ”) of at least 2.0x its initial investment in the Company (through the Parent), as determined by the Board in good faith, and (B) the remaining 50% of the Performance-Based
Options will vest upon the occurrence of any liquidity event in connection with which TPG realizes an MoM of at least 3.0x its initial investment in the Company (through the Parent), as determined by the Board in good faith, provided, that in the
event the liquidity event occurs prior to the second anniversary of the Effective Date, the MoM in clause (B) of this Section 2(c) shall be 2.0x, and in the event the liquidity event occurs on or after the second anniversary, but prior to the third
anniversary, of the Effective Date, the MoM in clause (B) of this Section 2(c) shall be 2.5x. TPG shall make a good faith projection with respect to the expected value of any such liquidity event, and, to the extent such projection, if accurate,
would result in vesting of some or all of the Performance-Based Options, the Performance-Based Options shall be deemed vested to the applicable extent and solely for the purpose of permitting the Executive to participate in such liquidity event with
the Shares underlying such Performance-Based Options.
  Notwithstanding the foregoing, in the event of a change in
control (as defined in below), TPG shall cause the buyer to (i) cancel all vested and exercisable Options and pay to the Executive, in cash or other property depending on, and in the same proportion as, the consideration received by TPG, an amount
equal to the excess, if any, of the fair market value of a Share on such change in control over the exercise price of such Option (such excess, if any, the “ Option Spread ”) for each such vested and exercisable Option, and (ii) cancel all
unvested Time-Based Options and pay to the Executive, in cash or other property depending on, and in the same proportion as, the consideration received by TPG, an amount equal to the aggregate Option Spread for each such unvested Time-Based Option,
plus interest at a reasonable rate to be determined by the Board, on the earlier to occur of (x) the date such unvested Time-Based Option would otherwise have vested, provided that the Executive is actively employed with the Company or an affiliate
on such date, or (y) subject to Section 11(k), within five (5) business days following the Date of Termination of the Executive’s employment as a result of a termination by the Company without Cause or by the Executive for Good Reason.
  For purposes of this Agreement, “ Change in Control *”* shall mean the occurrence of any of the following events after the Effective Date: (i) any sale, lease, exchange or other transfer (in one transaction or a series of related
transactions) of all or substantially all of the assets of the Company or the Parent on a consolidated basis to any person or group of related persons for purposes of Section 13(d) of the Exchange Act (a “ Group ”), together with any affiliates thereof other than to TPG or its
affiliates; (ii) the approval by the holders of the outstanding voting power of the Company or the Parent of any plan or proposal for the liquidation or dissolution of the Company; (iii) (A) any person or Group (other than TPG or its affiliates)
shall become the beneficial owner (within the meaning of Section 13(d) of the Exchange Act), directly or indirectly, of shares representing more than 40% of the aggregate outstanding voting power of the Company or the Parent and such person or Group
actually has the power to vote such shares in any such election and (B) TPG and its affiliates beneficially owns (within the meaning of Section 13(d) of the Exchange Act), directly or indirectly, in the aggregate a lesser percentage of the voting
power of the Company or the Parent than such other person or Group; (iv) the replacement of a majority of the board of directors of the Company or the Parent over a two-year period from the directors who constituted such board at the beginning of
such period, and such replacement shall not have been approved by a vote of at least a majority of such board then still in office who either were members of such board at the beginning of such period or whose election as a member of such board was
previously so approved or who were nominated by, or designees of, TPG or its affiliates; or (v) consummation of a merger or consolidation of the Company or the Parent with another entity in which holders of shares of the Company or Parent
immediately prior to the consummation of the transaction hold, directly or indirectly, immediately following the consummation of the transaction, less than 50% of the common equity interest in the surviving corporation in such transaction and TPG
and its affiliate do not hold a sufficient amount of voting power (or similar securities) to elect a majority of the surviving entity’s board of directors.
  Upon any termination of the Executive’s employment, any Options that are not vested and exercisable as of such termination and that do not become
vested and exercisable as a result of such termination shall automatically expire on the Date of Termination (as defined in Section 4(b) below). Any Options that have become vested and exercisable as of (or that become exercisable as a result of)
the Date of Termination shall expire on the earlier of (i) ninety (90) days after the date the Executive’s employment is terminated for any reason other than Cause, death or Disability; (ii) one year after the date the Executive’s
employment is terminated by reason of death or Disability; (iii) the commencement of business on the date the Executive’s employment is terminated for Cause; or (iv) the tenth anniversary of the grant date. All Options that are outstanding as
of the tenth anniversary of the grant date will expire on such date. The Executive shall be permitted to exercise the vested portion of the Options through net-physical settlement (i.e., by delivery of Shares net of the number of Shares having a
value equal to the applicable exercise price and applicable withholding taxes at the minimum statutory rate) if such exercise occurs after termination of the Executive’s employment pursuant to Sections 3(a) or 3(b), by the Company
pursuant to Paragraph 3(d) or by the Executive pursuant to Section 3(e) for Good Reason.  The Option shall be granted pursuant to and subject to the terms of a Management Equity Incentive Plan (the “ Plan ”), which shall contain rights to dividend equivalents in a manner intended
to comply with Section 409A of the Code.
  (d) The Executive shall roll over all shares in the Company that the Executive holds as a capital asset prior
to the Effective Date and such other amounts as are worth, in the aggregate, $1,200,000 on an after-tax basis into Shares of the Parent pursuant to and in accordance with a letter agreement between the Executive and Parent, dated as of December 15,
2006 (the “ Rollover Agreement ”).
  (e) The purchase of any Shares upon the exercise of the Options, or any other purchase or issuance of Shares contemplated by this Agreement, including pursuant to any rollover as
provided above, will be subject to the Executive’s execution of a Management Stockholders’ Agreement for the Company and the Parent in such form as provided by the Company and the Parent (the “ Management Stockholders’ Agreement ” and, together with the Option
Agreements, the “ Equity Agreements ”) for the Company, which
will include, among other things, (1) restrictions on transfer of the Shares and call rights by the Company, (2) certain drag-along and tag-along rights and obligations, (3) certain lock-up rights in connection with any underwritten public offering
of equity securities of the Company or any affiliate and (4) that Executive make such representations and execute such documents as the Company determines are reasonably necessary or appropriate to comply with any applicable securities or tax law
requirements, to qualify for any exemption from any applicable securities laws or to ensure Executive’s compliance with his obligations under the Management Stockholders’ Agreement. Notwithstanding anything to the contrary in the
Management Stockholders’ Agreement, the Company call right shall not apply to the Shares of the Parent purchased or otherwise acquired pursuant to the Rollover Agreement unless the Executive’s employment is terminated by the Company or
its affiliates for Cause or by the Executive without Good Reason or other than as a result of Retirement. For purposes of this Section 2(e), “ Retirement ” shall mean the Executive is eligible to retire without penalty or a
reduction in benefits under any tax qualified pension plan maintained by the Company and in which the Executive is eligible to participate.
  (f) During the Employment Period: (i) except as provided in the last sentence of this Section 2(f), the Executive and/or the Executive’s family, as the case may be, shall be
entitled to participate in all employee benefit plans, practices, policies, programs and arrangements of the Company which are made available generally to other executive officers of the Company and/or their families, as the case may be, including,
without limiting the Company’s right to terminate, modify or amend such plans in accordance with their terms or as provided in the immediately succeeding sentence, the Company’s benefits restoration program, life insurance, long-term
disability and health plans and (ii) the Executive shall be entitled to the perquisites and other fringe benefits that are made available by the Company to its senior executives generally, subject to any applicable terms and conditions of any
specific perquisite or other fringe benefit. Until the second anniversary of the Effective Date, except as consented to by the Executive, the Company agrees that the employee benefit plans, policies, programs and arrangements and perquisites and
other fringe benefits that are made available to the Executive during the Employment Period will not be materially diminished in the aggregate from those benefit plans, policies, programs and arrangements and perquisites and fringe benefits made
available immediately prior to the Effective Date. For the avoidance of doubt, such other plans, practices, policies, programs or arrangements shall not include any plan, practice, policy, program or arrangement that provides benefits in the nature
of severance or continuation pay.
  (g) The Company shall reimburse the Executive for all reasonable business expenses upon the presentation of
statements of such expenses in accordance with the Company’s policies and procedures now in force or as such policies and procedures may be modified with respect to all senior executive officers of the Company.
  (h) In the event the Company or the Parent engages in a significant subsequent corporate transaction with another entity, the Board will reconsider the size of the equity pool,
taking into account the larger size of the resultant entity and taking into account all relevant circumstances, including competitive market data for companies of similar size and circumstance.

  It is impossible to measure in money the damages that will
accrue to the Company in the event that the Executive breaches any of the restrictive covenants provided in Sections 7 and 8 hereof. In the event that the Executive breaches any such restrictive covenant, the Company shall be entitled to an
injunction restraining the Executive from violating such restrictive covenant (without posting any bond). If the Company shall institute any action or proceeding to enforce any such restrictive covenant, the Executive hereby waives the claim or
defense that the Company has an adequate remedy at law and agrees not to assert in any such action or proceeding the claim or defense that the Company has an adequate remedy at law. The foregoing shall not prejudice the Company’s right to
require the Executive to account for and pay over to the Company, and the Executive hereby agrees to account for and pay over, the compensation, profits, monies, accruals or other benefits derived or received by the Executive as a result of any
transaction constituting a breach of any of the restrictive covenants provided in Sections 7 and 8 hereof.
  10. Section 280G .    If, after the Effective Date, there occurs a transaction that constitutes a “change of control” under Regulation 1.280G of the Internal Revenue
Code of 1986, as amended (the “ Code ”), the Parent and the
Executive shall use commercially reasonable best efforts to take such actions as may be necessary to avoid the imposition of any the excise tax imposed by Section 4999 of the Code on the Executive, including seeking to obtain stockholder approval in accordance with the terms of Section 280G(b)(5) .
  11.

 or to such other address as any party hereto may designate

  (b) Except as expressly provided herein with respect to the Severance Agreement, this Agreement shall
constitute the entire agreement among the parties hereto with respect to the Executive’s employment hereunder, and supersedes and is in full substitution for any and all prior understandings or agreements with respect to the Executive’s
employment (it being understood that any Options and Shares shall be governed by the relevant Equity Agreements). The Executive’s employment with the Company for purposes of this Agreement shall include the Executive’s employment by any
direct or indirect subsidiary of the Parent or the Company.
  (c) This Agreement may be amended only by an instrument in writing signed by the parties hereto, and any
provision hereof may be waived only by an instrument in writing signed by the party or parties against whom or which enforcement of such waiver is sought. The failure of any party hereto at any time to require the performance by any other party
hereto of any provision hereof shall in no way affect the full right to require such performance at any time thereafter, nor shall the waiver by any party hereto of a breach of any provision hereof be taken or held to be a waiver of any succeeding
breach of such provision or a waiver of the provision itself or a waiver of any other provision of this Agreement.
  (d) The parties hereto acknowledge and agree that each party has reviewed and negotiated the terms and
provisions of this Agreement and has had the opportunity to contribute to its revision. Accordingly, the rule of construction to the effect that ambiguities are resolved against the drafting party shall not be employed in the interpretation of this
Agreement. Rather, the terms of this Agreement shall be construed fairly as to both parties hereto and not in favor or against either party.
  (e) (i)    This Agreement is binding on and is for the benefit of the parties hereto and their respective successors, assigns, heirs, executors, administrators and
other legal representatives. Neither this Agreement nor any right or obligation hereunder may be assigned by the Executive.
  (ii) The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business and/or assets of the Company to assume this Agreement in the same manner and to the same extent that the Company would have been required to perform it if no such succession had taken place. As
used in the Agreement, “the Company” shall mean both the Company as defined above and any such successor that assumes this Agreement, by operation of law or otherwise.
  (f) Any provision of this Agreement (or portion thereof) which is deemed invalid, illegal or unenforceable in any jurisdiction shall, as to that jurisdiction and subject to this
Section, be ineffective to the extent of such invalidity, illegality or unenforceability, without affecting in any way the remaining provisions thereof in such jurisdiction or rendering that or any other provisions of this Agreement invalid,
illegal, or unenforceable in any other jurisdiction. If any covenant should be deemed invalid, illegal or unenforceable because its scope is considered excessive, such covenant shall be modified so that the scope of the covenant is reduced only to
the minimum extent necessary to render the modified covenant valid, legal and enforceable. No waiver of any provision or violation of this Agreement by the Company shall be implied by the Company’s forbearance or failure to take
action.
  (g) The Company may withhold from any amounts payable to the Executive hereunder all federal, state, city or
other taxes that the Company may reasonably determine are required to be withheld pursuant to any applicable law or regulation, (it being understood, that, except as provided in section 5 of the Severance Agreement, the Executive shall be
responsible for payment of all taxes in respect of the payments and benefits provided herein).
  (h) This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without reference to its principles of conflicts of law.
  (i) This Agreement may be executed in several counterparts, each of which shall be deemed an original, but all of which shall constitute one and the same instrument. A facsimile of a
signature shall be deemed to be and have the effect of an original signature.
  (j) The headings in this Agreement are inserted for convenience of reference only and shall not be a part of
or control or affect the meaning of any provision hereof.
  (k) Notwithstanding anything to the contrary herein, in the event any payment hereunder would result in the
imposition of an excise tax pursuant to Section 409A of the Code or the regulations thereunder, as amended (the “ 409A Excise Tax ”), the Executive agrees that such payment shall be postponed to the date that is the earliest date upon which such payment would no longer result in the imposition of a
409A Excise Tax.
   
 IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above.
