Corporate Governance

Board of Directors

Our business and affairs are managed under the
direction of our Board of Directors. Our bylaws provide that our Board of Directors will consist of between three and eleven Directors. Our Board of Directors has determined that the Board shall consist of seven Directors, four of which will be
independent.

Our business and affairs are overseen by our Board of Directors pursuant to applicable laws and regulations and
our bylaws. Members of the Board of Directors are kept informed of our business through discussions with members of management, by reviewing materials provided to them and by participation in Board and Committee meetings. Regular attendance at Board
meetings and the annual meeting is required of each Director. Members of the Board of Directors are elected annually by the stockholders. All Board Members attended the 2011 annual meeting or participated via conference call.

Until April 2011, the Chairman of the Board and the Chief Executive Officer were separate individuals. Our prior Chairman was not
independent, as he was an officer of Providence Equity Partners, a large stockholder. Effective April 15, 2011, Tim McEwen, President and Chief Executive Officer, was elected as the Chairman of the Board. The Board had previously designated
Thomas F. Hedrick as the Independent Presiding Director, and, effective as of April 14, 2011, the Board designated Ruth E. Orrick to be the Independent Presiding Director. Our independent Directors meet in executive session at least five times
annually to review any topics specifically delegated to them by the Board and any other topics the independent Directors determine. The Independent Presiding Director has the following responsibilities:



| |  |  | to convene, chair and determine agendas for executive sessions;
| | - |  | ---------------------------------------------------------------



| |  |  | to determine in consultation with the Chairman the schedule for Board meetings, agenda items and the Boards related information needs;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | to assist the Board in the evaluation of senior management and communication of such evaluation to the CEO;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | to serve as an information resource for other Directors and act as a liaison between Directors, committee chairs and management
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | to liaise with stockholders, rating agencies and regulators; and
| | - |  | ----------------------------------------------------------------



| |  |  | to speak for the Board in circumstances where it is appropriate for the Board to have a voice distinct from that of management.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------

Our Board of Directors has determined that this leadership structure is appropriate; it segregates
authority between independent and non-independent members of the Board and provides representation to minority investors.

The
Board met 13 times during 2011, with 96% attendance of the Directors. No Director attended less than 85% of the meetings during their service on the Board for 2011.

Director Independence

In making independence determinations, the Board of
Directors observes all criteria for independence established by the SEC, NASDAQ and other governing laws and regulations. Our Board of Directors has affirmatively determined that Messrs. Hall, Hedrick and Stovall and Ms. Orrick are independent
Directors under the rules of NASDAQ and that Messrs. Hall, Hedrick and Stovall and Ms. Orrick are independent Directors as such term is defined in Rule 10A-3(b)(1) under the Exchange Act. Mr. Powell was also determined to be an independent
Director under the rules of NASDAQ until he resigned from the Board on April 5, 2011. Mr. Stovall was elected to the Board as an independent director on June 8, 2011.

As of April 5, 2011, as a result of Michael Powells resignation from the Board,
we were no longer in compliance with NASDAQs majority independent board composition requirements as set forth NASDAQ Listing Rule 5605(b)(1), which requires listed companies to maintain an independent majority board. Consistent with NASDAQ
Listing Rule 5605(b)(1)(A), NASDAQ provided us with a cure period of 180 days from the time of the event causing the Companys non-compliance in order to regain compliance. As a result of Mr. Stovalls appointment to the Board of
Directors on June 8, 2011, we regained compliance. On June 10, 2011, we received a letter from NASDAQ, confirming our compliance with NASDAQ Listing Rule 5605(b)(1).

Director Nominations

Either the Board or stockholders may recommend
candidates for the Board of Directors. Stockholders wishing to submit candidates should provide the information about the candidate to be considered in writing to the Nominating and Corporate Governance Committee, c/o Archipelago Learning, Inc.,
3232 McKinney Avenue, Suite 400, Dallas, Texas 75204. Candidate information should include the candidates name, home and business contact information, detailed biographical data and qualifications, information regarding any relationships
between the candidate and us within the last three years and evidence of the nominating persons ownership of our stock. Such recommendations must also include a statement from the recommending stockholder in support of the candidate,
particularly within the context of the criteria for Board membership, including issues of character, judgment, diversity, age, independence, expertise, corporate experience, length of service, other commitments and the like, personal references, and
an indication of the candidates willingness to serve.

In selecting Director candidates proposed by either the Board or
stockholders, the Nominating and Corporate Governance Committee considers whether the candidates possess the required skill sets and fulfill the qualification requirements of Directors approved by the Board, including integrity, objectivity, sound
judgment, leadership, courage and diversity. Diversity characteristics considered by the Nominating and Corporate Governance Committee include the types of experience and skills held by the Board members, including finance, operational, strategy,
risk, regulatory and oversight experience and skills, the current commitments of the Board members and the perspective of the Board members, including representation of large stockholders, management, and minority investors. The diversity of the
Board is one of the factors utilized in the annual review of the Board performed by the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee considers the current composition of the Board, the annual
evaluation of the Board of Directors as a whole and the performance of individual Directors, in order to determine the types of experience and skills that are required by the Board with its current members. While the Nominating and Corporate
Governance Committee has not established specific minimum qualifications for Director candidates, the Nominating and Corporate Governance Committee believes that candidates and nominees must reflect a Board that is comprised of Directors who
(1) are predominantly independent, (2) are of high integrity, (3) have broad, business-related knowledge and experience at the policy-making level in business or technology, including their understanding of the education and/or
Software as a Service industry and Archipelago Learnings business in particular, (4) have qualifications that will increase overall Board effectiveness and (5) meet other requirements as may be required by applicable rules, such as
financial literacy or financial expertise with respect to Audit Committee members.

With regard to candidates who are properly
recommended by stockholders or by other means, the Nominating and Corporate Governance Committee will review the qualifications of any such candidate, which review may, in the Nominating and Corporate Governance Committees discretion, include
interviewing references for the candidate, direct interviews with the candidate, or other actions that the Nominating and Corporate Governance Committee deems necessary or proper. In evaluating and identifying candidates, the Nominating and
Corporate Governance Committee has the authority to retain and terminate any third party search firm that is used to identify Director candidates and has the authority to approve the fees and retention terms of any search firm. The Nominating and
Corporate Governance Committee will apply these same principles when evaluating Board candidates who may be elected initially by the full Board to fill vacancies or add additional Directors prior to the Annual Meeting of stockholders at which
Directors are elected. After completing its review and evaluation of Director candidates, the Nominating and Corporate Governance Committee recommends the Director nominees to the full Board of Directors for consideration.

Code of Business Conduct and Ethics

We have adopted a code of business conduct and ethics that applies to all of our employees, officers and Directors, including those
officers responsible for financial reporting. These standards are designed to deter wrong doing and to promote honest and ethical conduct. The code of business conduct and ethics is available on our website at www.archipelagolearning.com. Any
amendments to the code, or any waivers of its requirements, will be disclosed on our website.

Indemnification of Officers and Directors

Our certificate of incorporation and bylaws provide that we will indemnify our Directors and officers to the fullest
extent permitted by Delaware General Corporation Law, or DGCL. We have directors and officers liability insurance that insures such persons against the costs of defense, settlement or payment of a judgment under certain circumstances.

In addition, our certificate of incorporation provides that our Directors will not be liable for monetary damages for breach
of fiduciary duty, except for liability relating to any breach of the Directors duty of loyalty, acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, violations under Section 174 of
the DGCL or any transaction from which the Director derived an improper personal benefit.

We have also entered into
indemnification agreements with each of our executive officers and Directors. The indemnification agreements provide the executive officers and Directors with contractual rights to indemnification, expense advancement and reimbursement, to the
fullest extent permitted under the DGCL.

Board Role in Risk Oversight

Our Board of Directors is responsible for oversight of our risk assessment and management process. The Board has delegated to the
Compensation Committee basic responsibility for oversight of managements compensation risk assessment, and has delegated to the Audit Committee tasks related to risk process oversight. In exercising its oversight duties, the Board receives
reports from each committee regarding the committees considerations and actions. The Audit Committees process includes working with the Chief Financial Officer and other members of management and receiving reports on enterprise risk
management, including managements assessment of risk exposures (including risks related to liquidity, credit, operations and regulatory compliance, among others), and the processes in place to monitor and control such exposures. The Audit
Committee may also, from time to time, receive updates between meetings from the Chief Executive Officer, the Chief Financial Officer and other members of management relating to risk oversight matters.

Communications to the Board of Directors

Stockholders may submit communications to the Board of Directors in writing by sending them to the Board of Directors, c/o Archipelago Learning, Inc., 3232 McKinney Avenue, Suite 400, Dallas, Texas 75204,
along with a copy of documentation showing the stockholders current holding in our common stock. All such communications are forwarded to the Lead Presiding Director, who receives and reviews them, forwards such communications to the
appropriate committee of the Board of Directors or non-employee Director, and facilitates an appropriate response.

COMPENSATION DISCUSSION AND ANALYSIS

This compensation discussion and analysis section provides information about the material elements of the compensation paid, awarded to or earned by our named executive officers, who consist
of our chief executive officer, our current and former executive vice president and chief financial officer, and our three other most highly compensated executive officers for the fiscal year ended December 31, 2011. For 2011, the named
executive officers were:



|               |  |

|Tim McEwen     |  | Chairman, Chief Executive Officer and President            
|Mark S. Dubrow |  | Executive Vice President and Chief Financial Officer       
|Julie Huston   |  | Executive Vice President, Global Sales

|Martijn Tel    |  | Executive Vice President and Chief Operating Officer       
|Jim Walburg    |  | Former Executive Vice President and Chief Financial Officer

On January 31, 2011, Mr. Walburg resigned as Chief Financial Officer. The Board named Mark S.
Dubrow as Executive Vice President, Chief Financial Officer and Secretary effective as of January 31, 2011.

This
compensation discussion and analysis section addresses and explains the compensation practices that were followed in 2011 and prior periods, the numerical and related information in the summary compensation and other tables presented below as well
as a discussion of our anticipated future compensation policy and approach.

History

Prior to our initial public offering in November 2009, we were a privately held company with a limited number of equity holders. As such,
we were not subject to NASDAQ listing requirements or SEC rules requiring a majority of our Board of Directors be independent or relating to the formation and functioning of Board committees, including a Compensation Committee. We established a
Compensation Committee in connection with our initial public offering. Beginning in June 2011, our Compensation Committee is comprised of three Directors that meet the definition of outside directors for the purposes of
Section 162(m) of the Internal Revenue Code of 1986, as amended and the definition of a non-employee director for the purposes of Section 16 of the Exchange Act and are independent Directors under NASDAQ rules.

Most, if not all, of our prior compensation policies have been the product of negotiations between the named executive officers and our
founders or the board of managers of Archipelago Learning Holdings, LLC, our subsidiary and reporting entity prior to a corporate reorganization enacted in contemplation of our initial public offering in November 2009. Subsequent to our initial
public offering, the Compensation Committee is responsible for implementing and administering all aspects of our benefits and compensation plans and programs.

The terms of all employment agreements in place prior to our initial public offering were negotiated by the employee and the board of managers of Archipelago Learning Holdings, LLC or our Board of
Directors. Compensation decisions for 2011 relating to our named executive officers who were party to employment agreements, including the determination of annual bonuses and other incentive-based awards, were made by our Board of Directors. See
Employment Agreements for discussion of our employment agreements with certain of out executive officers, including our named executive officers.

Objectives and Philosophy of Executive Compensation Policy

Our objective is to maintain a compensation policy that provides a competitive total executive compensation package that attracts and
retains individuals of exceptional ability and managerial talent in a highly competitive market. Our executive compensation program is designed to align executive compensation with our key strategic, financial and operational goals and with the
long-term interests of our stockholders.

In 2010 we engaged an independent outside compensation consultant to construct a
peer group of companies, provide market information, provide advice on market practices and support specific decisions regarding compensation for named executives. For 2011, the Compensation Committee made certain determinations in consultation with
and based on recommendations by Mr. McEwen.

For 2011, the Compensation Committee reviewed overall company and individual
performance, as well as the applicable terms of any employment agreements, in connection with the review and determination of each named executive officers compensation. For overall company performance, the Compensation Committee reviewed and
considered invoiced sales, revenue and Cash EBITDA. As an emerging growth company, we believe that increasing revenue and profitability are directly related to increasing stockholder value and linking compensation with company performance in these
areas is supportive of the long-term interests of stockholders. Ms. Hustons performance was also based on the achievement of sales goals, including overall sales, new business sales and sales to existing customers. For individual
performance, the Compensation Committee reviews the executives achievement of non-financial objectives and consults with and considers the recommendations of Mr. McEwen. The Compensation Committee may also make compensation decisions on a
discretionary basis.

Invoiced sales and Cash EBITDA are defined as follows:



| |  |  | We recognize invoiced sales in the period in which the purchase order or other evidence of an arrangement is received and the invoice is issued, which
may be at a different time than the commencement of the subscription. Under GAAP, revenue for invoiced sales is deferred and recognized ratably over the subscription term beginning on the commencement date of the applicable subscription. This
difference between non-GAAP invoiced sales and GAAP revenue in a given period is equal to the change in the deferred revenue balance for that period.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cash EBITDA is defined by invoiced sales less operating expenses, excluding stock-based compensation and unusual items.
| | - |  | -----------------------------------------------------------------------------------------------------------------------

During 2009 and 2010, we used Adjusted EBITDA as a key measure in determining our performance and therefore, Adjusted EBITDA was another
factor the board of managers, and subsequently the board of directors considered in making adjustments to annual bonus payments. Adjusted EBITDA is a term defined in our credit agreement, which includes operating income, adjusted for depreciation,
amortization, the change in deferred revenue, stock-based compensation, and other permitted items, such as acquisition expenses, severance, executive recruitment, certain professional services, agency fees and unusual, non-recurring charges.

In future periods, the Compensation Committee may engage an independent outside compensation consultant to construct a peer
group of companies, provide market information, provide advice on market practices and support specific decisions regarding compensation for named executive officers. In addition, Messrs. McEwen and Dubrow, in consultation with the Board of
Directors, establish annual budgets, including sales targets and other performance-related goals, which the Compensation Committee may consult in making decisions with respect to bonuses and other payments.

Tax and Accounting Considerations

While we generally considered the financial accounting and tax implications of our executive compensation, neither element was a material consideration in the compensation awarded to our named executive
officers in 2011.

##### Table of Contents

Elements of Executive Compensation

Our executive compensation includes the following elements: base salaries, annual performance bonuses, an equity compensation plan, a
defined contribution plan and a benefits package.

During the 2011 Annual Meeting of Shareholders held on June 8, 2011,
the shareholders voted to approve the compensation of our named executive officers. Although the vote was non-binding, the Board of Directors and Compensation Committee value the opinions of the shareholders and considered their voting when making
compensation decisions.

Base Salary

We establish base salaries for our executive officers generally based on the scope and essential elements of each of his or her duties, as well as the abilities, performance and experience of the named
executive officers. We seek to set these salaries competitively, with the intent to attract and retain our key executive officers. Each of Messrs. McEwens, Dubrows, Lowreys, Tels, Walburgs, and Ms. Hustons
employment agreements establish their respective base salaries, which may be increased at the discretion of the Board of Directors, at the recommendation of the Compensation Committee, based on their evaluation of our performance over the year, the
executive officers performance of his or her duties and the impact of the executive officers performance in driving our growth and earnings. We use invoiced sales, revenue, and Cash EBITDA as key measures in determining our performance
and, therefore, are measures the Board of Directors and the Compensation Committee may consider in making adjustments to base salaries. We anticipate that the Board of Directors and the Compensation Committee may consider market practice in
adjusting base salaries as well.

The Compensation Committee approved increases in each of Messrs. McEwen, Lowrey, Tel and
Ms. Hustons base salaries for 2011. See details in Employee Agreements. We expect that the Compensation Committee will consult with Messrs. McEwen and Dubrow and continue to assess adjustments to base salaries in a similar
manner in future periods.

Annual Performance Bonus

We believe it is important to provide cash incentive bonuses to provide incentives for our executive officers to meet annual company and
individual objectives established by our Board of Directors, in consultation with Messrs. McEwen and Dubrow (other than bonuses for the Chief Executive Officer and Chief Financial Officer, which were established solely by our Board of Directors),
and to reward performance for meeting those objectives.

Bonus arrangements are identified in employment agreements and are
generally determined by company performance as measured against the budget for the applicable year. For a discussion of the bonus arrangements in the employment agreements for the named executive officers and for amounts awarded in 2011, see
Employment Agreements and Grants of Plan-Based Awards in 2011. In 2011, the Board of Directors reviewed and approved an alternate incentive calculation for executives. The performance bonus was calculated on a sliding scale
of Target (defined as 50% of base salary for Executive Vice Presidents), reflecting the financial challenges faced during the year, and individual performance level. In 2010, the Board of Directors approved bonuses to our named officers at their
Target amounts, per their employment agreements. In 2009, the Board of Directors approved bonuses to our named officers at their maximum amounts, per their employment agreements.

During 2011, we considered invoiced sales, revenue, and Cash EBITDA to be key measure in determining our performance and therefore, the
Board considered these as key measures considered in making adjustments to annual bonus payments. During 2010 and 2009, we considered Adjusted EBITDA as a key measure in determining our performance and therefore, the Board considered Adjusted EBITDA
as a key measure considered in making adjustments to annual bonus payments. We anticipate that the Compensation Committee will also exercise a measure of discretion in determining bonus awards in future periods based on similar factors.

##### Table of Contents

Ms. Huston, as the Executive Vice President, Global Sales, was eligible for a
performance bonus twice a year, as set forth in her employment agreement, and prior to her entry into an employment agreement, as established by the Board of Directors in consultation with Messrs. McEwen and Dubrow, reflecting performance during the
two six-month sales cycles in a calendar year, ending in June and December. Historically, Messrs. McEwen and Dubrow have determined Ms. Hustons bonus based on the results during the applicable period as compared with target sales levels,
previously set according to a formula tied to overall sales results for the business and specific performance targets. Bonus payments for Messrs. McEwen, Walburg, Lowrey, and Tel are made once a year, after our financial results for the year are
available. Employees who are not party to employment agreements are also eligible for annual performance bonuses. Bonus payments for our other employees are made twice a year, based on six-month performance periods.

The Compensation Committee will consult with Messrs. McEwen and Dubrow and will consider performance against other key measures such as
invoiced sales, revenue and Cash EBITDA to assess these performance bonuses in future periods.

Equity Compensation
Plans

2007 Equity Compensation Plan

Upon the Companys acquisition by Providence Equity Partners in 2007, we established the 2007 Equity Compensation Plan as a long-term compensation program for our executive officers and certain other
employees using equity-based awards and accordingly compensate our executive officers and certain other employees based on the value of our equity. We believe that when our executive officers possess an ownership interest in us, they have a
continuing stake in our long-term success.

Under the 2007 Equity Compensation Plan, we granted Class B and Class C shares in
Archipelago Learning Holdings, LLC to our executive officers and certain other employees in accordance with the terms of the Archipelago Learning Holdings, LLC Agreement. These participation shares were granted to employees who we determined to be
key employees for our business, in connection with certain employee promotions and to certain newly hired employees. The Class B shares vested over time subject to the participants continued employment by or service to Archipelago Learning,
LLC. The Class C shares were subject to performance hurdles and holders of the Class C shares were only entitled to distributions if he or she was employed by or provided service to Archipelago Learning, LLC at the time that distributions were made.

No holder of Class B or Class C shares was eligible to receive distributions, as the holders of the Class A and did not
receive distributions equal to 100% of their capital contributions and a preferred return of 12% per annum on the Class A capital contributions.

The reorganization completed prior to our initial public offering in November 2009 was treated as a liquidation event of Archipelago Learning Holdings, LLC, and holders of Class B shares and Class C
shares received our common stock and restricted common stock in an amount equal to the value they would have received upon a liquidation of Archipelago Learning Holding, LLC with liquidation proceeds implied by the initial public offering price.
Executive officers and employees who held Class B shares received common stock for all vested shares and restricted common stock, subject to time-based vesting over the same schedule their existing Class B shares vested, for all unvested shares.
Executive officers who held Class C shares received restricted common stock, subject to vesting based on performance measures, including the return on investment of Providence Equity Partners through distributions or sales. Employees who held Class
C shares received common stock. No additional awards will be granted under the 2007 Equity Compensation Plan.

2009 Omnibus
Incentive Plan

We adopted our 2009 Omnibus Incentive Plan, or (the 2009 Plan), in connection with our initial
public offering. The 2009 Plan became effective in November 2009 and a total of 2,198,172 shares of our common

stock were reserved for issuance. The 2009 Plan provides for grants of nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, other stock-based awards
and performance-based compensation. Directors, officers and other employees of us and our subsidiaries, as well as other individuals performing services for us, are eligible for grants under the 2009 Plan. The purpose of the 2009 Plan is to provide
incentives that will attract, retain and motivate highly competent officers, Directors, employees and other service providers by providing them with appropriate incentives and rewards either through a proprietary interest in our long-term success or
compensation based on their performance in fulfilling their personal responsibilities. The following is a summary of the material terms of the 2009 Plan, but does not include all of the provisions of the 2009 Plan. For further information about the
2009 Plan, we refer you to the complete copy of the 2009 Plan, as filed with the SEC.

The 2009 Plan provides for its
administration by the Compensation Committee of our Board of Directors or any committee designated by our Board of Directors to administer the 2009 Plan. The Compensation Committee is empowered to determine the form, amount and other terms and
conditions of awards, clarify, construe or resolve any ambiguity in any provision of the 2009 Plan or any award agreement and adopt such rules, forms, instruments and guidelines for administering the 2009 Plan as it deems necessary or proper. All
actions, interpretations and determinations by the Compensation Committee or by our Board of Directors are final and binding.

The 2009 Plan makes available an aggregate of 2,198,172 shares of our common stock, subject to adjustments, of which 1,115,033
remains available for future issuance as of December 31, 2011. In the event that any outstanding award expires, is forfeited, cancelled or otherwise terminated without the issuance of shares or is otherwise settled for cash, shares of our
common stock allocable to such award, to the extent of such forfeiture, cancellation, expiration, termination or settlement for cash, shall again be available for the purposes of the 2009 Plan. If any award is exercised by tendering shares of our
common stock to us, either as full or partial payment, in connection with the exercise of such award under the 2009 Plan or to satisfy our withholding obligation with respect to an award, only the number of shares of our common stock issued net of
such shares tendered will be deemed delivered for purposes of determining the maximum number of shares of our common stock then available for delivery under the 2009 Plan.

Members of our Board of Directors, as well as employees of, and service providers to, us or any of our subsidiaries and affiliates are eligible to participate in the 2009 Plan. The selection of
participants is within the sole discretion of the Compensation Committee.

The 2009 Plan provides for the grant of
nonqualified stock options, incentive stock options, stock appreciation rights, shares of restricted stock, or restricted stock, other stock-based awards and performance-based compensation, collectively, the awards. The
Compensation Committee will, with regard to each award, determine the terms and conditions of the award, including the number of shares subject to the award, the vesting terms of the award, and the purchase price for the award. Awards may be made in
assumption of or in substitution for outstanding awards previously granted by us or our affiliates, or a company acquired by us or with which we combine.

Awards granted under the 2009 Plan shall be evidenced by award agreements (which need not be identical) that provide additional terms and conditions associated with such awards, as determined by the
Compensation Committee in its sole discretion; provided, however, that in the event of any conflict between the provisions of the 2009 Plan and any such award agreement, the provisions of the 2009 Plan shall prevail.

An option granted under the 2009 Plan permits a participant to purchase from us a stated number of shares at an option price established
by the Compensation Committee, subject to the terms and conditions described in the 2009 Plan, and such additional terms and conditions, as established by the Compensation Committee, in its sole discretion, that are consistent with the provisions of
the 2009 Plan. Options shall be designated as either a nonqualified stock option or an incentive stock option, provided that options granted to non-employee Directors

##### Table of Contents

and other non-employee service providers shall be nonqualified stock options. An option granted as an incentive stock option shall, to the extent it fails to qualify as an incentive stock option,
be treated as a nonqualified option. None of us, including any of our affiliates or the Compensation Committee, shall be liable to any participant or to any other person if it is determined that an option intended to be an incentive stock option
does not qualify as an incentive stock option. Each option shall conform to the requirements of the 2009 Plan, and may contain such other provisions as the Compensation Committee shall deem advisable.

The exercise price of an option granted under the 2009 Plan may not be less than 100% of the fair market value of a share of our common
stock on the date of grant, provided the exercise price of an incentive stock option granted to a person holding greater than 10% of our voting power may not be less than 110% of such fair market value on such date. The Compensation Committee will
determine the term of each option at the time of grant in its discretion; however, the term may not exceed ten years (or, in the case of an incentive stock option granted to a ten percent stockholder, five years).

A stock appreciation right entitles the holder to receive, upon its exercise, the excess of the fair market value of a specified number
of shares of our common stock on the date of exercise over the grant price of the stock appreciation right. The payment of the value may be in the form of cash, shares of our common stock, other property or any combination thereof, as the
Compensation Committee determines in its sole discretion. Subject to the terms of the 2009 Plan and any applicable award agreement, the grant price (which shall not be less than 100% of the fair market value of a share of our common stock on the
date of grant), term, methods of exercise, methods of settlement, and any other terms and conditions of any stock appreciation right shall be determined by the Compensation Committee. The term of a stock appreciation right may not exceed
10 years.

An award of restricted stock is a grant of a specified number of shares of our common stock, which are subject
to forfeiture upon the occurrence of specified events. Each award agreement evidencing a restricted stock grant shall specify the period(s) of restriction, the number of shares of restricted stock subject to the award, the performance, employment or
other conditions (including the termination of a participants service whether due to death, disability or other cause) under which the restricted stock may be forfeited to the company and such other provisions as the Compensation Committee
shall determine. The Compensation Committee may require that the stock certificates evidencing such shares be held in custody or bear restrictive legends until the restrictions thereon shall have lapsed. Unless otherwise determined by the
Compensation Committee and set forth in the award agreement, a participant holding restricted stock will not have the right to vote and will not receive dividends with respect to such restricted stock.

The Compensation Committee, in its sole discretion, may grant awards of shares of our common stock and awards that are valued, in whole
or in part, by reference to, or are otherwise based on the fair market value of, such shares (the other stock-based awards). Such other stock-based awards shall be in such form, and dependent on such conditions, as the Compensation
Committee shall determine, including, without limitation, the right to receive one or more shares of our common stock (or the equivalent cash value of such stock) upon the completion of a specified period of service, the occurrence of an event
and/or the attainment of performance objectives. Subject to the provisions of the 2009 Plan, the Compensation Committee shall determine to whom and when other stock-based awards will be made, the number of shares of our common stock to be awarded
under (or otherwise related to) such other stock-based awards, whether such other stock-based awards shall be settled in cash, shares of our common stock or a combination of cash and such shares, and all other terms and conditions of such awards.

To the extent permitted by Section 162(m) of the Internal Revenue Code, or the Code, the Compensation Committee is
authorized to design any award so that the amounts or shares payable and distributable thereunder are treated as qualified performance-based compensation within the meaning of Section 162(m) of the Code. The vesting, crediting
and/or payment of performance-based compensation shall be based on the achievement of objective performance goals based on one or more of the following measures: (a) consolidated earnings before or after taxes (including earnings before
interest, taxes, depreciation and amortization); (b) net income; (c) operating

income; (d) earnings per share; (e) book value per share; (f) return on stockholders equity; (g) expense management; (h) return on investment; (i) improvements
in capital structure; (j) profitability of an identifiable business unit or product; (k) maintenance or improvement of profit margins; (l) stock price; (m) market share; (n) revenues or sales; (o) costs; (p) cash
flow; (q) working capital; and (r) return on assets. Such measures may be used to measure our performance or the performance of any of our business units and may be used to compare our performance against the performance of a group of
comparable companies, or a published index.

Unless otherwise determined by the Compensation Committee, an award shall not be
transferable or assignable by a participant except in the event of his or her death (subject to the applicable laws of descent and distribution) and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall
be void and unenforceable against us or any of our subsidiaries or affiliates. Any permitted transfer of the awards to heirs or legatees of a participant shall not be effective to bind us unless the Compensation Committee has been furnished with
written notice thereof and a copy of such evidence as the Compensation Committee may deem necessary to establish the validity of the transfer and the acceptance by the transferee or transferees of the terms and conditions of the 2009 Plan.

Except as otherwise provided in the applicable award agreement, a participant has no rights as a stockholder with respect to
shares of our common stock covered by any award until the participant becomes the record holder of such shares.

In the event
of any corporate event or transaction such as a merger, consolidation, reorganization, recapitalization, separation, stock dividend, stock split, reverse stock split, split up, spin-off, combination of shares of our common stock, exchange of shares
of our common stock, dividend in kind, extraordinary cash dividend, or other like change in capital structure (other than normal cash dividends) to our stockholders, or any similar corporate event or transaction, the Compensation Committee, to
prevent dilution or enlargement of participants rights under the 2009 Plan, shall substitute or adjust, in its sole discretion, the number and kind of shares that may be issued under the 2009 Plan or under particular forms of awards, the
number and kind of shares subject to outstanding awards, the option price, grant price or purchase price applicable to outstanding awards, the annual award limits, and/or other value determinations applicable to the 2009 Plan or outstanding awards.

Upon the occurrence of a change in control, unless otherwise specifically prohibited under applicable laws or by the rules
and regulations of any governing governmental agencies or national securities exchanges, or unless the Compensation Committee shall determine otherwise in the award agreement, the Compensation Committee is authorized (but not obligated) to make
adjustments in the terms and conditions of outstanding awards, including without limitation the following (or any combination thereof): (i) continuation or assumption of such outstanding awards under the 2009 Plan by us (if it is the surviving
company or corporation) or by the surviving company or corporation or its parent; (ii) substitution by the surviving company or corporation or its parent of awards with substantially the same terms for such outstanding awards;
(iii) accelerated exercisability, vesting and/or lapse of restrictions under all then outstanding awards immediately prior to the occurrence of such event; (iv) upon written notice, provide that any outstanding awards must be exercised, to
the extent then exercisable, within fifteen days immediately prior to the scheduled consummation of the event, or such other period as determined by the Compensation Committee (in either case contingent upon the consummation of the event), and at
the end of such period, such awards shall terminate to the extent not so exercised within the relevant period; and (v) cancellation of all or any portion of outstanding awards for fair value (as determined in the sole discretion of the
Compensation Committee) which, in the case of options and stock appreciation rights, may equal the excess, if any, of the value of the consideration to be paid in the change of control transaction to holders of the same number of shares subject to
such options or stock appreciation rights (or, if no such consideration is paid, fair market value of the shares subject to such outstanding awards or portion thereof being canceled) over the aggregate option price or grant price, as applicable,
with respect to such awards or portion thereof being canceled.

Our Board of Directors may amend, alter, suspend, discontinue,
or terminate the 2009 Plan or any portion thereof or any award (or award agreement) thereunder at any time.

##### Table of Contents

To the extent that the 2009 Plan and/or awards are subject to Section 409A of the
U.S. Internal Revenue Code, or (the Code), the Compensation Committee may, in its sole discretion and without a participants prior consent, amend the 2009 Plan and/or awards, adopt policies and procedures, or take any other
actions (including amendments, policies, procedures and actions with retroactive effect) as are necessary or appropriate to (a) exempt the 2009 Plan and/or any award from the application of Section 409A of the Code, (b) preserve the
intended tax treatment of any such award, or (c) comply with the requirements of Section 409A of the Code, Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such
regulations or other guidance that may be issued after the date of the grant. This plan shall be interpreted at all times in such a manner that the terms and provisions of the 2009 Plan and awards are exempt from or comply with Section 409A
guidance.

The Compensation Committee will determine, subject to any employment agreements, any future equity awards that each
named executive officer will be granted pursuant to the 2009 Omnibus Incentive Plan.

Amended and Restated Employee Stock
Purchase Plan

We adopted our initial Employee Stock Purchase Plan, or the ESPP, in connection with our initial public
offering in November 2009. On June 9, 2010, our Board of Directors and shareholders approved the Amended and Restated ESPP. The following is a summary of the material terms of the Amended and Restated ESPP, but does not include all of the
provisions of the ESPP. For further information about Amended and Restated ESPP, we refer you to the complete copy of the plan, as filed with the SEC.

The purpose of the ESPP is to give eligible employees the opportunity to purchase shares of our common stock through the use of payroll deductions. The plan is intended to qualify as an employee stock
purchase plan under Section 423 of the Internal Revenue Code, which will provide U.S. participants with certain tax benefits upon their subsequent sale or other disposition of shares of our common stock that they will purchase under the terms
of the plan. The ESPP is generally available to all eligible employees, including our named executive officers under the same offering and eligibility terms, and is not tied to any performance criteria. The ESPP is not subject to any of the
provisions of the Employee Retirement Income Security Act of 1974, as amended.

The ESPP is administered by our Compensation
Committee or any other subcommittee of the Board designated by our Board to administer the ESPP. The administrator has the authority to interpret the ESPP, to establish, amend and rescind any rules and regulations relating to the ESPP, and to make
any other determinations that it deems necessary or desirable for the administration of the ESPP. All actions taken and all interpretations and determinations made by the administrator are final and binding upon the participants and the Company and
the participating subsidiaries.

Shares of our common stock issuable under the ESPP may be either newly issued shares,
treasury shares or shares we reacquire, including by purchase on the open market. 500,000 shares have been reserved pursuant to the existing ESPP and 490,724 shares remain available for issuance as of December 31, 2011, subject to adjustment.

If any change is made to our outstanding shares of common stock in connection with any merger, consolidation, reorganization,
recapitalization, stock split, stock dividend, or other like change, the administrator may make appropriate adjustments to, without limitation, the number or kind of shares subject to the ESPP and the purchase price of such shares in order to
prevent dilution or enlargement of participants rights and to maintain the continuing availability of shares under the ESPP.

Shares of our common stock are offered for purchase under the ESPP during one or more offering periods, the timing of which is designated by the administrator. Offering periods are generally anticipated
to be six months in length. An employee who participates in the ESPP for a particular offering period will have the right to purchase shares of our common stock on the terms and conditions set forth below.



19



---

##### Table of Contents

In general, all of our full-time employees, including employees of any of our subsidiaries
designated as a participating subsidiary are eligible to participate in the ESPP. In no event may an employee be granted a right to purchase shares of our common stock under the ESPP if, immediately after the grant, the employee would own shares of
our common stock possessing five percent or more of the total combined voting power or value of all classes of our capital shares or the capital shares of any of our subsidiaries. The administrator may, in its discretion, exclude employees
(i) who have not been continuously employed by a participating subsidiary for up to two years, (ii) certain highly compensated employees and (iii) who customarily work less than twenty hours per week or five months per year.

Eligible employees who enroll in the ESPP may elect to have between one and ten percent of their eligible compensation
withheld and accumulated for the purchase of shares of our common stock at the end of each offering period in which they participate. A participant may not elect to purchase more than $25,000, or a lesser amount determined by the Board, worth of
shares of our common stock (based on the fair market value of shares of our common stock determined at grant date) in any calendar year and may not purchase more than 1,000 shares of our common stock during any single offering period.

Each participant may cancel his or her election to participate in the ESPP by written notice to the administrator in such form and at
such times as the administrator may require and any accumulated payroll deductions will be returned to the participant. Participation shall end automatically upon termination of employment for any reason.

Amounts accumulated for each participant will be used to purchase shares of our common stock at the end of each offering period. The per
share purchase price will be determined by the administrator, but shall not be less than 85 percent of the lesser of (i) the fair market value of a share on the first date of the offering period and (ii) the fair market value of a share on
the last date of the offering period. Any amounts not used for the purchase of shares of our common stock shall be returned to the participant. No purchase rights will be assignable or transferable by the participant.

As soon as practicable following the end of each offering period, the number of shares of our common stock purchased by each participant
will be deposited into an account established in the participants name with a stock brokerage firm designated by the Board of Directors.

The ESPP is intended to provide shares of our common stock for investment by employees and not for resale. We do not intend to restrict or influence any participant from selling shares of our common stock
purchased under the ESPP, subject to compliance with applicable law.

No participant will have any rights as a stockholder
with respect to the shares of our common stock covered by his or her purchase right until the shares are actually purchased on the participants behalf. No adjustment will be made for dividends, distributions, or other rights for which the
record date is prior to the date of such purchase.

Our Board of Directors may amend or terminate the ESPP at any time,
subject to applicable law. Upon a termination shares of our common stock may be issued to participants and any amounts not applied to the purchase of shares of our common stock shall be refunded to the participants.

The following summarizes only the federal income tax consequences of participation under the ESPP based upon federal income tax laws in
effect on the date of this Proxy Statement. This summary does not purport to be complete, and does not discuss any non-U.S., state or local tax consequences. In addition, the discussion does not address tax consequences which may vary with, or are
contingent on, a participants individual circumstances. Each participant in the ESPP is strongly urged to consult with his or her tax advisor regarding participation in the ESPP.

##### Table of Contents

The ESPP, and the right of participants to make purchases thereunder, is intended to qualify
under the provisions of Sections 421 and 423 of the federal tax code (except to comply with applicable foreign or local law). Under these provisions, no income will be taxable to a participant at the time of grant of the option or purchase of
shares of our common stock. Amounts deducted from a participants pay under the ESPP are part of the employees regular compensation and remain subject to federal, state and local income and employment withholding taxes.

Upon disposition of shares of our common stock, the participant will generally be subject to tax, the amount of which will depend upon
the participants holding period. If the participant disposes of his or her shares more than two years after the date of option grant and more than one year after the purchase of the shares, the lesser of (i) 15 percent of the fair market
value of the shares on the date the option was granted or (ii) the excess (or zero if there is no excess) of the fair market value of the shares on the date of the disposition of the shares over the purchase price will be treated as ordinary
income, and any further gain will be treated as long-term capital gain. If the participant disposes of the shares before the expiration of these holding periods, the excess of the fair market value of the shares on the exercise date over the
purchase price will be treated as ordinary income, and any further gain or loss on such disposition will be long-term or short-term capital gain or loss, depending on the holding period.

We are not entitled to a deduction for amounts taxed as ordinary income or capital gain to a participant except to the extent of ordinary
income reported by participants upon disposition of shares of our common stock within two years from date of grant or within one tax year of the date of purchase.

Other Benefits

We provide the following benefits to our named
executive officers on the same basis as other eligible employees:



| |  |  | health, vision and dental insurance;
| | - |  | ------------------------------------



| |  |  | life insurance;
| | - |  | ---------------



| |  |  | long-term and short-term disability; and
| | - |  | ----------------------------------------



| |  |  | a 401(k) defined contribution retirement plan.
| | - |  | ----------------------------------------------

In addition, we provide a matching contribution to all employees of up to 3% of employee contributions to the defined contribution retirement plan, plus 50% of the amount of the plan participants
deferred compensation that exceeds 3% of the participants compensation, but not in excess of 5% of the participants compensation.

Impact on Equity Compensation Plans of Plato Merger

On March 3, 2012, we entered into an Agreement and Plan of Merger (the Merger Agreement) with Plato Learning, Inc., a Delaware corporation (Plato) and Project Cayman Merger
Corp., a wholly owned subsidiary of Plato, pursuant to which Project Cayman Merger Corp. will be merged with and into us, and we will become a wholly owned subsidiary of Plato (the Merger). Our board of directors (the Board),
acting upon the unanimous recommendation of the Transaction Committee comprised of independent directors of the Board, unanimously recommended that our stockholders approve the Merger Agreement and the Merger.

Upon the Merger becoming effective, we will become a wholly owned subsidiary of Plato, and each share of our common stock issued and
outstanding immediately prior to the effective date of the Merger will be converted into the right to receive $11.10 in cash, without interest and less applicable taxes (Merger Consideration), on the terms and subject to the conditions
set forth in the Merger Agreement. As of the effective date of the Merger, all such shares of our common stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of such common stock shall
cease to have any rights with respect thereto, except the right to receive the Merger Consideration.



21

##### Table of Contents

Under the terms of the Merger Agreement, at the effective date of the Merger:



| |  |  | each outstanding stock option (whether vested or unvested) will be cancelled and converted into the right to receive a payment in cash equal to the
excess, if any, of $11.10 over such options exercise price;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | each outstanding share of our restricted common stock that is vested or that, upon consummation of the Merger, will automatically vest in accordance
with its terms, will be cancelled and converted into the right to receive a payment in cash equal to the Merger Consideration;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | each outstanding restricted stock unit (whether vested or unvested) and related dividend equivalent right will be cancelled and converted into the
right to receive a payment in cash equal to the Merger Consideration, which amounts will be paid to certain or our employees; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | each outstanding shadow option (whether vested or unvested) that represents the right to receive a cash payment based on the value of our common stock
upon the occurrence of certain events will be cancelled and converted into the right to receive a cash amount equal to the excess, if any, of the Merger Consideration per share over our closing stock price on the date of grant.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Each share of restricted stock that is unvested at the effective time of the Merger and is not
automatically vested pursuant to its terms upon consummation of the Merger will be forfeited, without any consideration paid to the holder thereof. Additionally, each outstanding stock option that has an exercise price equal to or greater than
$11.10 will be cancelled without the right to receive any cash payment or other consideration. As a result of the vesting of the equity awards, noted above, any remaining unamortized compensation expense related to each respective equity award will
be recognized at that time.

See footnote (3) below for discussion of Mr. Waburgs options.

See footnote (4) below for discussion of Ms. Hustons options.



|(3) | Mr. Walburg retired from his position as our Chief Financial Officer, effective on January 31, 2011, and continued on in a consulting role for a three month
Transition Period. Mr. Walburgs unvested stock options were forfeited as of the end of the Transition Period. In accordance with Mr. Walburgs Separation Agreement, Mr. Walburgs restricted stock vested as follows: 50%
of Mr. Walburgs restricted common stock subject to time-based vesting vested on January 10, 2011, 50% of his restricted common stock subject to time- based vesting vested on January 10, 2012, and all of his restricted common
stock subject to vesting based on performance measures vested on January 10, 2011.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(4) | Ms. Huston resigned from her position as our Executive Vice President, Global Sales, effective on January 31, 2012, at which time her unvested stock options
and restricted stock were forfeited. Ms. Huston has 90 days commencing on January 31, 2012 during which she may exercise any vested options.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(5) | Mr. Lowrey resigned from his position as our Executive Vice President and Chief Technology Officer, effective on January 1, 2012, and is continuing on in a
consulting role for a three to nine month transition period.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(6) | Our outstanding stock options, restricted stock, and restricted stock units at the effective time of the Merger will be treated as follows under the Merger Agreement:
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Stock Options. At the effective time of the Merger, each outstanding stock option, whether or not vested, will be cancelled and converted into
the right to receive a cash payment equal to the excess, if any, of $11.10 over such options exercise price. Each outstanding stock option that has an exercise price equal to or greater than $11.10 will be cancelled without the right to
receive any consideration.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Restricted Stock. At the effective time of the Merger, each outstanding share of our restricted stock that is vested or that, upon consummation
of the Merger, automatically vests in accordance with its terms, will be cancelled and converted into the right to receive $11.10 in cash, without interest and less applicable withholding tax. Any share of our restricted stock that is unvested at
the effective time of the Merger and that does not automatically vest pursuant to its terms upon the Merger will be forfeited without the right to receive any consideration.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Restricted Stock Units. At the effective time of the Merger, each outstanding restricted stock unit and related dividend equivalent right,
whether or not vested, will be cancelled and converted into the right to receive $11.10 in cash, without interest, plus any accumulated dividends, which amounts will be paid to certain employees of Archipelago.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The table reflects the vesting of the stock options, restricted stock, and restricted stock units in accordance with the underlying
equity agreements, and does not consider the timing of the Merger and the resulting impact on the vesting of these awards as a result of the Merger.



|(7) | The achievement of the performance hurdles were not considered to be probable and could not be estimated as of December 31, 2011. However, as a result of the
Merger Agreement with Plato, 247,805 shares of Mr. McEwens and 56,280 of Mr. Lowreys performance-based restricted stock are expected to vest at the time of the Merger.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(8) | On February 24, 2011, we issued an aggregate of 28,038 restricted stock units Mr. McEwen. Subject to Mr. McEwens continued
service, the restricted stock units vest as follows: 41 2/3% (11,682 restricted shares) vested on August 24, 2011 and were settled in cash in an amount determined based on the price of the common stock and the remainder (16,356 restricted
shares) shall vest on the fourth (4th) anniversary of
the grant date and be settled in common stock.

|Item 12. | Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters
|-------- | ----------------------------------------------------------------------------------------------

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS, DIRECTORS AND MANAGEMENT

The following table sets forth certain information as of April 23, 2012, by (a) each person known by us that beneficially owns
5% or more of our outstanding shares of common stock based on their filings of Schedules 13D and 13G with the SEC, (b) each of our directors and named executive officers and (c) all of our current directors and executive officers as a
group.

Beneficial ownership of shares is determined under rules of the SEC and generally includes any shares over which a
person exercises sole or shared voting or investment power. In addition, shares are deemed to be beneficially owned by a person if the person has the right to acquire shares (for example, upon exercise of an option) within sixty (60) days of
that date. The following table includes shares of restricted stock that will vest in connection with the Merger, but does not include stock options and RSUs that will be cancelled and converted into the right to receive certain cash payments in
connection with the Merger.

Percentage of beneficial ownership is based on 26,345,675 shares of common stock and restricted
stock outstanding as of April 23, 2012. Except as noted by footnote, and subject to community property laws where applicable, we believe based on the information provided to us that the persons and entities named in the table below have sole

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our Directors and executive officers and holders of more
than 10% of our common stock to file initial reports of ownership and reports of changes in their beneficial ownership of our common stock with the SEC. Such persons are required by the SEC regulations to furnish us with copies of all
Section 16(a) reports they file.

Based solely upon a review of such reports or written representations furnished to us
that no other reports were required, we believe that during the year ended December 31, 2011, all of our executive officers, Directors, and greater than 10% beneficial owners complied with all applicable Section 16(a) filing requirements.

Related Party Transactions

We have adopted a Related Person Transaction
Policy, which can be found on our website, www.archipelagolearning.com. Our Audit Committee reviews and approves or ratifies all relationships and related person transactions between us and (i) our Directors, Director nominees or executive
officers, (ii) any 5% record or beneficial owner of our common stock or (iii) any immediate family member of any person specified in (i) and (ii) above. Our controller is primarily responsible for the development and
implementation of processes and controls to obtain information from our Directors and executive officers with respect to related party transactions and for determining, based on the facts and circumstances, whether we or a related person have a
direct or indirect material interest in the transaction.

As set forth in the related person transaction policy, in the course
of its review and approval or ratification of a related party transaction, the Audit Committee will consider:



| |  |  | the nature of the related persons interest in the transaction;
| | - |  | ---------------------------------------------------------------



| |  |  | the availability of other sources of comparable products or services;
| | - |  | ---------------------------------------------------------------------



| |  |  | the material terms of the transaction, including, without limitation, the amount and type of transaction; and
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | the importance of the transaction to us.
| | - |  | ----------------------------------------

Any member of the Audit Committee who is a related person with respect to a transaction under review will not be permitted to participate in the discussions or approval or ratification of the transaction.
However, such member of the Audit Committee will provide all material information concerning the transaction to the Audit Committee.

The Audit Committee has ratified or approved the following related party transactions or relationships for the year ended December 31, 2011.

connection with the identification, evaluation and acquisition of businesses. MHT Securities, L.P. is an affiliate of MHT-SI, L.P. and MHT-SI GP, L.L.C., both stockholders in the Company. Under the terms of the agreement, we must pay a transaction
fee to MHT Securities, L.P. upon the successful consummation of a merger, acquisition, consolidation, divestiture or similar transaction with any company initially identified and contacted by MHT Securities, L.P. as a potential acquisition for the
Company. The amount of this transaction fee is dependent upon the size of the acquisition, but in no circumstances less than $250,000. Effective in October 2011, we amended the agreement with MHT Securities, L.P., increasing the transaction from a
minimum of $250,000 to $650,000. Additionally, any reasonable expenses incurred in connection with this agreement are reimbursed. During the year ended December 31, 2011, we incurred an aggregate of $0.3 million under this agreement related to
the acquisition of Alloy and other transactions, which was accrued in accounts payable as of December 31, 2011.

Providence Equity Partners beneficially owns 47% of our outstanding shares of common stock. Providence Equity Partners paid for certain
costs related to travel and other expenses of members of our Board of Directors and other staff assisting those Directors in certain oversight functions and invoiced us for reimbursement. During each of the year ended December 31, 2011, $0.2
million of these costs were paid by us.

We purchase equipment from CDW Corporation, a portfolio company of Providence Equity
Partners. Equipment purchases with this supplier totaled $0.9 million for the year ended December 31, 2011.

As part of
the sale of TeacherWeb, we signed a transition services agreement with Edline whereby we performed certain accounting and administrative functions related to TeacherWeb for a period that was subsequently extended through October 31, 2010.
During the transition period, we paid certain costs on behalf of TeacherWeb, which were billed to and reimbursed by Edline. We received no fee for the performance of these services. No amounts have been paid to TeacherWeb vendors on behalf of Edline
for the year ended December 31, 2011. Additionally, we agreed to pay severance costs for one employee for a period of one year, ending October 31, 2011 to be reimbursed by Edline. For the year ended December 31, 2011, we paid $0.2
million to TeacherWeb on behalf of Edline related to these severance payments.

On October 4, 2011, Archipelago Learning,
LLC, our wholly owned subsidiary, entered into an Agreement with Bulldog Super Holdco, Inc., a Delaware corporation, which became the ultimate parent company of Blackboard, Inc. Pursuant to the Agreement, Archipelago Learning, LLC sold 656,882
shares of Series A Preferred Stock in Edline for a total of approximately $12.2 million. In addition, we received approximately $2.1 million for a notes receivable and a dividend of approximately $0.6 million in connection with the Edline Sale. The
Edline Sale represented our entire investment in Edline. We recorded a gain of $6.4 million before tax. As a result of the Edline Sale, Tim McEwen, our Chairman, President and Chief Executive Officer, has resigned from the Board of Directors of
Edline, on which he had previously served. The Edline Sale was in connection with a series of transactions pursuant to which Blackboard was acquired by affiliates of Providence Equity Partners, which beneficially owns 47% of our outstanding shares
of common stock and pursuant to which Edline became a subsidiary of Blackboard.

Our wholly owned subsidiary, EducationCity
U.K., leases office space in Rutland, U.K. which is owned by the pension funds of two of our former officers and stockholders. We made payments under this lease for $0.2 million for the year ended December 31, 2011. We concluded during purchase
accounting that this lease is a market based lease.

In connection with the purchase of EducationCity, we incurred a $5.0
million note payable to the sellers, payable in equal installments on December 31, 2010 and 2011. Upon the purchase, the sellers became officers of the Company and stockholders. As of December 31, 2011, we have fully paid this note
payable.

REPORT OF THE AUDIT COMMITTEE

In accordance with its written charter adopted by the Board of Directors, the Audit Committee reports to and acts on behalf of the Board
of Directors to oversee managements conduct of, and the integrity of, the Companys financial reporting, the Companys systems of internal control over financial reporting, the qualifications, engagement, compensation, independence
and performance of the independent registered public accounting firm, the Companys legal and regulatory compliance, the application of the Companys Related Person Transaction Policy, and the application of the Companys Code of
Business Conduct and Ethics and Executive Code of Ethics.

The Companys management has responsibility for preparing the
Companys consolidated financial statements and the Companys independent auditors (independent registered public accountants), Deloitte & Touche LLP, or Deloitte, are responsible for auditing those consolidated financial
statements. In this context, the Audit Committee has met with management and Deloitte to review and discuss the Companys audited financial statements. The Companys management has represented to the Audit Committee that the financial
statements were prepared in accordance with generally accepted accounting principles. The Audit Committee discussed with Deloitte the matters required to be discussed by the Statement on Auditing Standards No. 61, Communications with
Audit Committees, as amended, and the Sarbanes-Oxley Act of 2002, and had the opportunity to ask Deloitte questions relating to such matters. The discussions included the quality, and not just the acceptability, of the accounting principles
utilized, the reasonableness of significant accounting judgments, and the clarity of disclosures in the financial statements. The Audit Committee also discussed with management the process for certifications by the Companys Chief Executive
Officer and Chief Financial Officer, which are required by the Securities and Exchange Commission and the Sarbanes-Oxley Act of 2002 for certain of the Companys filings with the Securities and Exchange Commission.

The Audit Committee reviewed with the Companys independent registered public accountants the overall scope and plans for their
audits for 2011. The Audit Committee also received regular updates from management on internal control and business risks and on compliance and ethics issues. The Audit Committee meets with the internal and independent registered public accountants,
with and without management present, to discuss their evaluations of the Companys internal controls and the overall quality of the Companys financial reporting.

The Audit Committee reviewed and discussed with Deloitte, Deloittes independence and, as part of that review, received the written disclosures required by applicable professional and regulatory
standards relating to Deloittes independence from the Company. The Audit Committee also reviewed and pre-approved all fees paid to the independent registered public accountants as. The Audit Committee concluded that the independent registered
public accountants are independent from the Company and its management.

The Audit Committee has reviewed and discussed with
management its assessment and report on the effectiveness of the Companys internal control over financial reporting as of December 31, 2011, which it made using the criteria set forth by the Committee of Sponsoring Organizations of the
Treadway Commission in Internal Control  Integrated Framework. The Audit Committee also has reviewed and discussed with Deloitte its review and report on the Companys internal control over financial reporting. The Company
published these reports in its Annual Report on Form 10-K for the fiscal year ended December 31, 2011, which was filed with the Securities and Exchange Commission on March 15, 2012.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors, and the Board
has approved, that the audited financial statements be included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2011, filed with the Securities and Exchange Commission on March 15, 2012.

Respectfully submitted,

THE AUDIT COMMITTEE
