INTRODUCTIONTrubion Pharmaceuticals, Inc. ("Trubion" or the "Company") is committed to good corporate citizenship. Our policy is to conduct our business affairs honestly and ethically. This Code of Business Conduct and Ethics ("Code") provides a general statement of Trubion's expectations regarding the ethical standards to which each director, employee, including officers, and contractor should adhere while acting on Trubion's behalf. All of our employees, officers and directors must conduct themselves accordingly and seek to avoid even the appearance of improper behavior. Conduct in violation of this Code is unacceptable in the workplace and in any work-related setting outside the workplace. Any employee or contract worker who violates this Code will be subject to disciplinary action, up to and including termination of employment or engagement. Trubion strives to employ individuals with personal standards consistent with those of our Company: integrity, professionalism and commitment to superior results.
This Code of Business Conduct and Ethics is designed to deter wrongdoing and to promote:
This Code should help guide your conduct in the course of our business. Many of the principles described in this Code are, however, general in nature, and the Code does not cover every situation that may arise. Use common sense and good judgment in applying this Code. If you have any questions about applying the Code, it is your responsibility to seek guidance.
This Code is not the exclusive source of guidance and information regarding the conduct of our business. You should consult applicable policies and procedures in specific areas as they apply. The Code is intended to supplement, not replace, the Trubion Employee Handbook and the other policies and procedures of the Company.
We are committed to continuously reviewing and updating our policies and procedures. The Company therefore reserves the right to amend, alter, or terminate this Code at any time and for any reason, subject to applicable law.

YOUR RESPONSIBILITIES AS AN EMPLOYEE
GENERAL STANDARDS OF CONDUCTOverview
Honest and ethical conduct is critical to our business. All Trubion directors, employees, agents, and contractors have a duty to comply with applicable law and to act in an honest and ethical manner.
Compliance with law
You are responsible for complying with all laws, rules, regulations, and regulatory orders applicable to the conduct of our business, including the "good manufacturing practices," "good clinical practices" and "good laboratory practices" regulations implemented by the U.S. Food and Drug Administration. Personnel must comply with these and all other applicable laws, rules and regulations and must promptly alert a supervisor to any deviation from them.. If you are located or engaging in business outside of the United States, you must comply with laws, rules, regulations, and regulatory orders of the United States, including the Foreign Corrupt Practices Act and U.S. export rules and regulations, in addition to the applicable laws of other jurisdictions, including the jurisdiction in which you are located or engaging in business. If compliance with the Code should ever conflict with law, you must comply with the law.
You should undertake to acquire knowledge of the legal requirements relating to your duties sufficient to enable you to recognize potential dangers and to know when to seek advice from managers or other appropriate personnel.
In addition, scientific and research integrity is fundamental to the scientific process and to Trubion's ability to bring novel products to market. All Trubion research and development must be conducted according to all applicable laws and regulations and to the generally accepted ethical standards of the scientific community. Scientific misconduct, such as fabrication, falsification or plagiarism in proposing, conducting or reporting research, disregards the intellectual contributions and property of others, impedes the progress of research and corrupts the scientific record. It is prohibited.
Violations of laws, rules, regulations, and orders may subject you to individual criminal or civil liability, in addition to discipline by the Company. Violations may also subject the Company to civil or criminal liability or the loss of business.
No discrimination or harassment
The Company is committed to providing a work environment that is free of discrimination and harassment. The Company is an equal opportunity employer and makes employment decisions on the basis of merit and business needs. In addition, the Company strictly prohibits harassment of any kind, including harassment on the basis of race, color, veteran status, religion, gender, sex, sexual orientation, age, mental or physical disability, medical condition, national origin, marital status, or any other characteristics protected under federal or state law or local ordinance.
Health and safety
You are responsible for using good judgment to help ensure a safe and healthy workplace for all employees.

AVOIDING CONFLICTS OF INTERESTSOverview
Your decisions and actions in the course of your employment with the Company should be based on the best interest of the Company, and not based on personal relationships or benefits. You should seek to avoid situations where your personal activities and relationships conflict, or even appear to conflict, with the interests of the Company, except under guidelines approved by the Board of Directors. This includes situations where you may have or appear to have an indirect conflict through, for example, a significant other or a relative or other persons or entities with which you have a relationship. A conflict may also arise when you take actions or have interests that make it difficult for you to perform your work for the Company objectively and effectively. You must disclose to your manager any interest that you have that may, or may appear to, conflict with the interests of the Company.
There are a variety of situations in which a conflict of interest may arise. While it would be impractical to attempt to list all possible situations, some common types of conflicts are discussed below.
Outside employment and directorships
Unless you are a non-employee director of the Company, you may not perform services as a director, employee, agent, or contractor for a customer, a supplier or any other entity that has a business relationship with the Company without prior written approval from the Company's Legal Department. Non-employee directors of the Company must promptly inform the Company's Human Resources Department of any such service. You may not perform services as a director, employee, agent, or contractor for any competitor of the Company.
The following types of outside employment are strictly prohibited:
Financial interests in other companies
You should not have any financial interestincluding, for example, an indirect interest through a relative or significant otherin any organization if that interest would give you, or would appear to give you, a conflict of interest with the Company. You should be particularly sensitive to financial interests in competitors, suppliers, customers, distributors, and strategic partners.
Transactions with related parties
If you have a significant financial interest in a transaction between the Company and a third partyincluding, for example, an indirect interest through a relative or significant otheryou must disclose that interest (potentially considered a "related party"), and that interest must be approved in writing by the Company's Legal Department. We encourage you to seek guidance if you have any questions as to whether an interest in a transaction is significant. If it is determined that the transaction is required to be reported under SEC rules, the transaction will be subject to review and approval by the Audit Committee of the Board of Directors. Any dealings with a related party must be conducted in such a way that no preferential treatment is given to the related party.
Corporate opportunities
You may not directly or indirectly exploit for personal gain any opportunities that are discovered through the use of corporate property, information, or position unless the opportunity is disclosed fully in writing to the Board of Directors or its designated committee and the Board of Directors or its designated committee declines to pursue the opportunity.
Loans by the Company
Loans from the Company to directors and executive officers are prohibited. Loans from the Company to other officers and employees must be approved in advance by the Board of Directors or its designated committee.
Improper benefits
You may not receive any improper benefit as a result of your position with the Company.
Election or appointment to public office
You may serve in an elected or appointed public office provided that the position does not create or appear to create a conflict of interest.
Guidance and approvals
Evaluating whether a conflict of interest exists, or may appear to exist, requires the consideration of many factors. We encourage you to seek guidance and approval in any case where you have any questions or doubts. The Company may at any time rescind prior approvals to avoid a conflict of interest, or the appearance of a conflict of interest, for any reason deemed to be in the best interest of the Company.

PUBLIC COMMUNICATIONSPublic communications and filings
The Company files reports and other documents with regulatory authorities, including the United States Securities and Exchange Commission and the Nasdaq National Market. In addition, from time to time, the Company makes other public communications, such as issuing press releases.
Depending upon your position with the Company, you may be called upon to provide information to help assure that the Company's public reports and communications are complete, fair, accurate, and understandable. You are expected to use all reasonable efforts to provide complete, accurate, objective, relevant, timely, and understandable answers to inquiries related to the Company's public disclosures.
Individuals involved in the preparation of public reports and communications must use all reasonable efforts to comply with our disclosure controls and procedures, which are designed to ensure full, fair, accurate, timely, and understandable disclosure in our public reports and communications.
If you believe that any disclosure is materially misleading or if you become aware of any material information that you believe should be disclosed to the public, it is your responsibility to bring this information to the attention of the Company's Legal Department or Chief Financial Officer. If you believe that questionable accounting or auditing conduct or practices have occurred or are occurring, you should notify the Audit Committee of the Board of Directors. For additional details on how to report questionable accounting or auditing conduct or practices, please consult the Trubion Whistleblower Policy.
Communication procedures
You may not communicate externally on behalf of the Company unless you are authorized to do so. The Company has established specific policies regarding who may communicate information to the public, the press, market professionals (such as securities analysts, institutional investors, investment advisors, brokers and dealers) and security holders on behalf of the Company:
You should refer all calls or other inquiries from the press, market professionals or security holders to the Chief Financial Officer or his/her authorized designee, who will see that the inquiry is directed to the appropriate persons within the Company.
All communications made to public audiences on behalf of the Company, including formal communications and presentations made to investors, customers, or the press, require prior approval of the Legal Department and the Chief Financial Officer.

FINANCIAL REPORTINGOverview
As a public company, we are required to follow strict accounting principles and standards, to report financial information accurately and completely in accordance with these principles and standards, and to have appropriate internal controls and procedures to ensure that our accounting and financial reporting complies with law. The integrity of our financial transactions and records is critical to the operation of our business and is a key factor in maintaining the confidence and trust of our employees, security holders, and other stakeholders.
Compliance with rules, controls and procedures
It is important that all transactions are properly recorded, classified, and summarized in our financial statements and books and records in accordance with our policies, controls, and procedures, as well as all generally accepted accounting principles, standards, laws, rules, and regulations for accounting and financial reporting. If you have responsibility for or any involvement in financial reporting or accounting, you should have an appropriate understanding of, and you should seek in good faith to adhere to, relevant accounting and financial reporting principles, standards, laws, rules, and regulations and the Company's financial and accounting policies, controls, and procedures. If you are a senior officer, you should seek to ensure that the internal controls and procedures in your business area are in place, understood, and followed.
Accuracy of records and reports
It is important that those who rely on records and reportsmanagers and other decision makers, creditors, customers, and auditorshave complete, accurate, and timely information. False, misleading, or incomplete information undermines the Company's ability to make good decisions about resources, employees, and programs, and may, in some cases, result in violations of law. Anyone involved in preparing financial or accounting records or reports, including financial statements and schedules, must be diligent in assuring that those records and reports are complete, accurate, and timely. Anyone representing or certifying as to the accuracy of such records and reports should make an inquiry or review adequate to establish a good faith belief in their accuracy. Even if you are not directly involved in financial reporting or accounting, you are likely involved with financial records or reports of some kinda voucher, time sheet, purchase requisition, invoice, or expense report. In addition, most employees have involvement with product, marketing, or administrative activities, or performance evaluations, which can affect our reported financial condition or results. Therefore, the Company expects you, regardless of whether you are otherwise required to be familiar with finance or accounting matters, to use all reasonable efforts to ensure that every business record or report with which you deal is accurate, complete, and reliable.
Intentional misconduct
You may not intentionally misrepresent the Company's financial performance or otherwise intentionally compromise the integrity of the Company's reports, records, policies, and procedures. For example, you may not:
Dealing with auditors
Our auditors have a duty to review our records in a fair and accurate manner. You are expected to cooperate with independent and internal auditors in good faith and in accordance with law. In addition, you must not fraudulently induce or influence, coerce, manipulate, or mislead our independent or internal auditors regarding financial records, processes, controls, or procedures or other matters relevant to their engagement. You may not engage, directly or indirectly, any outside auditors to perform any audit, audit-related, tax, or other services, including consulting, without written approval from the Chief Financial Officer and the Audit Committee of the Board of Directors.
Obligation to investigate and report potential violations
You should make appropriate inquiries in the event you may see, for example:
Dishonest or inaccurate reporting can lead to civil or even criminal liability for you and the Company and can lead to a loss of public faith in the Company. You are required to promptly report any case of suspected financial or operational misrepresentation or impropriety.
Keeping the Audit Committee informed
The Audit Committee plays an important role in ensuring the integrity of our public reports. If you believe that questionable accounting or auditing conduct or practices have occurred or are occurring, you should notify the Legal Department of the Company or otherwise make a report under the Company's Whistleblower Policy, which includes the procedures for bringing the matter to the attention of the Audit Committee of the Board of Directors. In particular, the Chief Executive Officer and Chief Financial Officer should promptly bring to the attention of the Audit Committee any information of which he or she may become aware concerning, for example:
Reporting and remedial action
In the event the Company discovers (i) any intentional misconduct, questionable accounting, internal accounting controls, or audit matters, (ii) the reporting of any fraudulent financial information, or (iii) any other type of fraud, the Company will make any and all required disclosures to the appropriate law enforcement agencies (including any necessary disclosures in the Company's periodic reports that are filed with the Securities and Exchange Commission). The Company will also undertake a review of how any such events occurred (and could occur) and take all necessary steps to improve its internal controls or implement any procedures to prevent similar events from happening in the future. The Company will also communicate, as appropriate, any such new controls or procedures to all employees affected by them.

SAFEGUARDING COMPANY ASSETSOverview
All employees, agents, and contractors are responsible for the proper use of Company assets. This responsibility applies to all of the Company's assets, including your time, work and work product; cash and accounts; physical assets such as inventory, equipment, vehicles, computers, systems, facilities, and supplies; intellectual property, such as patents, copyrights, trademarks, and trade secrets; and other proprietary or nonpublic information.
Protecting the Company's information
In the course of your involvement with the Company, you may come into possession of information that has not been disclosed or made available to the general public. This nonpublic information may include, among other things:
If you have any questions as to what constitutes nonpublic information, please consult the Legal Department.
All nonpublic information must only be used for Company business purposes. You have an obligation to use all reasonable efforts to safeguard the Company's nonpublic information. You may not disclose nonpublic information to anyone outside of the Company, except when disclosure is required by law or when disclosure is required for business purposes and appropriate steps have been taken to prevent misuse of that information. This responsibility includes not disclosing nonpublic information in Internet discussion groups, chat rooms, bulletin boards, or other electronic media. In cases where disclosing nonpublic information is required or necessary, you should consult with the Legal Department. The misuse of nonpublic information is contrary to Company policy and may also be a violation of law.
From time to time you may need to disclose Company confidential information to potential business partners in order to further the Company's business. This disclosure, however, should never be done without carefully considering its potential benefits and risks. If you determine in consultation with your manager and other appropriate Company officers that disclosure of confidential information is necessary, you must then contact the Legal Department to ensure that an appropriate written nondisclosure agreement is signed prior to the disclosure. The Company has standard nondisclosure agreements suitable for most disclosures. You must not sign a third party's nondisclosure agreement or accept changes to the Company's standard nondisclosure agreements without review and approval by the Company's Legal Department. Many of these nondisclosure agreements require that confidential information be marked as confidential, and it is your responsibility to make sure that all the Company's confidential information is properly marked as confidential. In addition, all Company materials that contain Company confidential information, including presentations, must be reviewed and approved by the Company's Legal Department prior to publication or use.
When you joined the Company, you signed an agreement to protect and hold confidential the Company's proprietary information. This agreement remains in effect for as long as you work for the Company and even after you leave the Company. Under this agreement, you may not disclose the Company's confidential information to anyone or use it to benefit anyone other than the Company without the prior written consent of an authorized Company officer.
Prohibition on insider trading
You may not directly or indirectlythrough, for example, significant others, family members or controlled entitiesbuy or sell stocks or other securities of the Company or any other company based on nonpublic information obtained from your work at the Company. In addition, you may not "tip" others by providing them nonpublic information under circumstances that suggest that you were trying to help them make an investment decision. These obligations are in addition to your obligations with respect to nonpublic information generally, as discussed above.
Under United States securities laws, it is unlawful for any person who has "material" nonpublic information about a Company to trade in the stock or other securities of that Company or to disclose such information to others who may trade. Material nonpublic information is information about a Company that is not known to the general public and that a typical investor would consider important in making a decision to buy, sell or hold securities. Insider trading is a crime, penalized by fines of up to $5,000,000 and 20 years in jail for individuals. In addition, the government may seek the imposition of a civil penalty of up to three times the profits made or losses avoided from the trading. Insider traders must also disgorge any profits made, and are often subjected to an injunction against future violations. Finally, insider traders may be subjected to civil liability in private lawsuits. As a United States company, these United States securities laws apply to all Company employees, officers and directors even those who live or work in Company locations outside the United States.
You should be aware that stock market surveillance techniques are becoming increasingly sophisticated, and the probability that United States federal or other regulatory authorities will detect and prosecute even small-level trading is significant. Insider trading rules are strictly enforced, even in instances when the financial transactions seem small.
The Company has imposed a trading blackout period on members of the Board of Directors, executive officers, and certain designated employees who, as a consequence of their position with the Company, are more likely to be exposed to material nonpublic information about the Company. These directors, executive officers and employees may not trade in Company securities during the blackout period.
These policies are detailed in the Company's Insider Trading Policy, and if you have any questions at all regarding trading in the Company's securities, contact the Legal Department for guidance.
Prohibition against short selling of Company stock
Short sales (i.e., the sale of a security that must be borrowed to make delivery) and "selling short against the box" (i.e., a sale with a delayed delivery) with respect to the Company's securities are prohibited by the Company's Insider Trading Policy. Short sales may signal to the market possible bad news about the Company or a general lack of confidence in the Company's prospects, and an expectation that the value of the Company's securities will decline. In addition, if you are required to comply with Section 16 of the Securities Exchange Act of 1934 or the blackout periods or pre-clearance requirements of the Company's Insider Trading Policy, you are prohibited from engaging in transactions in publicly-traded options, such as puts and calls, and other derivative securities with respect to the Company's securities. This prohibition extends to any hedging or similar transaction designed to decrease the risks associated with holding Company securities. Even if you are not prohibited from engaging in derivatives transactions, you should exercise caution when doing so. Transactions in derivative securities may reflect a short term and speculative interest in the Company's securities and may create the appearance of impropriety, even where a transaction does not involve trading on inside information. Trading in derivatives may also focus attention on short term performance at the expense of the Company's long term objectives. In addition, the application of securities laws to derivatives transactions can be complex, and persons engaging in derivatives transactions run an increased risk of violating securities laws if not careful. These trading prohibitions apply to members of your immediate family, persons with whom you share a household, persons that are your economic dependents and any other individuals or entities whose transactions in securities you influence, direct or control. You are responsible for making sure that these other individuals and entities do not violate these trading prohibitions.
Maintaining and managing records
The Company is required by local, state, federal, foreign and other applicable laws, rules and regulations to retain certain records and to follow specific guidelines in managing its records. Records include paper documents, email, compact discs, computer hard drives, floppy disks, microfiche, microfilm, and all other recorded information, regardless of medium or characteristics. Civil and criminal penalties for failure to comply with such guidelines can be severe for employees, agents, contractors, and the Company. To the extent the Company maintains a document retention policy, all employees are expected to consult and follow such policy in managing the Company's records. You should consult with the Legal Department regarding the retention of records in the case of actual or threatened litigation or government investigation. The Legal Department will notify you if a legal hold is placed on records for which you are responsible. A legal hold suspends all document destruction procedures in order to preserve appropriate records under special circumstances, such as litigation or government investigations. The Legal Department determines and identifies what types of records or documents are required to be placed under a legal hold. If a legal hold is placed on records for which you are responsible, you must preserve and protect the necessary records in accordance with instructions from the Legal Department. Records or supporting documents that are subject to a legal hold must not be destroyed, altered or modified under any circumstance. A legal hold remains effective until it is officially released in writing by the Legal Department. If you are unsure whether a document has been placed under a legal hold, you should preserve and protect that document while you check with the Legal Department.
Computers and other equipment
The Company strives to furnish employees with the equipment necessary to efficiently and effectively do their jobs. You must care for that equipment and use it responsibly only for Company business purposes. If you use Company equipment at your home or off site, take precautions to protect it from theft or damage, just as if it were your own. If the Company no longer employs you, you must immediately return all Company equipment. While computers and other electronic devices are made accessible to you to assist you in performing your job and to promote the Company's interests, all such computers and electronic devices, whether or not used entirely or partially on the Company's premises or with the aid of the Company's equipment or resources, must remain fully accessible to the Company and, to the maximum extent permitted by law, will remain the sole and exclusive property of the Company.
You should not have any expectation of privacy with respect to information transmitted over, received by, or stored in any electronic communications device owned, leased, or operated in whole or in part by or on behalf of the Company. To the extent permitted by applicable law, the Company retains the right to gain access to any information received by, transmitted by, or stored in any such electronic communications device, by and through its employees, agents, contractors, or representatives, at any time, either with or without an employee's or third party's knowledge, consent or approval.
Software
All software used by you to conduct Company business must be appropriately licensed. Never make or use illegal or unauthorized copies of any software, whether in the office, at home, or on the road, since doing so may constitute copyright infringement and may expose you and the Company to potential civil and criminal liability. In addition, use of illegal or unauthorized copies of software may subject the employee to disciplinary action, up to and including termination. The Company's IT Department will inspect Company computers periodically to verify that only approved and licensed software has been installed. Any non-licensed/supported software will be removed.
Electronic usage
Posting or discussing information concerning the Company's products or business on the Internet without the prior written consent of the Company's Legal Department is prohibited. Other forms of electronic communication used by employees currently or in the future are also intended to be encompassed under this policy. It is not possible to identify every standard and rule applicable to the use of electronic communications devices, so if you are in doubt please ask the legal Department.

RESPONSIBILITIES TO OUR CUSTOMERS, SUPPLIERS AND COMPETITORSOverview
You should respect the rights of, and deal fairly with, the Company's customers, suppliers, business partners, and competitors in compliance with law. You should not take unfair advantage of anyone through deception, misrepresentation, manipulation, coercion, abuse of privileged information, or any intentional unfair business practice.
Improper payments
You should not authorize, offer, promise, give, solicit, or accept, money, gifts, entertainment, privileges, gratuities, benefits, or other items of value intended to improperly influence, directly or indirectly, any business decision or that otherwise violate law or create the appearance of impropriety. You should contact the Legal Department if you have any questions as to whether a payment is proper.
Gifts and entertainment
You may, from time to time, provide or accept business amenities to aid in building legitimate business relationships. Business amenities may include gifts, meals, services, entertainment, reimbursements, favors, privileges, or other items of value. It is never acceptable to accept cash or a cash equivalent (such as a check, money order, or voucher) from a vendor, supplier, or customer.
Any business amenity should be consistent with customary business practice and reasonable and appropriate for the circumstance. Business amenities should not be lavish or excessive. Business amenities should not violate law or create an appearance of impropriety, and it is never appropriate for you to ask for a gift. You should avoid providing or accepting any cash payment or any other business amenity that can be construed as a bribe or payoff. All Company funds expended for business amenities must be accurately recorded in the Company's books and records. Contact the Legal Department if you have any questions as to whether a business amenity is permissible. Those of you who work in sales and purchasing positions must be even more careful when it comes to relationships with suppliers and customers to avoid even the appearance of a conflict of interest. While it can be appropriate for employees in sales and purchasing positions to attend sporting or other events with suppliers or customers, you must make sure that you are not placing yourself or the Company in a potential conflict of interest situation. The key here is to ask whether your behavior will have, or appear to have, an inappropriate influence on your ability to make a decision. If you have any questions in this regard, you should talk to your supervisor or the Company's Legal Department. In some business situations outside of the United States, it is customary and lawful for business executives to present gifts to representatives of their business partners. These gifts may be of more than a nominal value, and under the circumstances, returning the gifts or paying for them may be an affront to the giver. If you find yourself in such a situation, you must report the gift to the Legal Department. In some cases, you may be required to turn the gift over to the Company.
Special restrictions apply when dealing with government employees. For more information, see the next section on "Working with Governments."
Selecting suppliers
The Company's policy is to select suppliers based on the merits of their products, services, and business practices and to purchase supplies based on need, quality, service, price, and other terms and conditions of sale. You may not establish a business relationship with any supplier if you know that its business practices violate applicable laws.
Handling the nonpublic information of others
You must handle the nonpublic information of others responsibly and in accordance with our agreements with them. Nonpublic information of others includes notes, reports, conclusions, and other materials prepared by a Company employee based on the nonpublic information of others.
You should not knowingly accept information offered by a third party, including a customer, supplier, or business partner, that is represented as nonpublic, or that appears from the context or circumstances to be nonpublic, unless an appropriate nondisclosure agreement has been signed with the party offering the information. You should contact the Legal Department to coordinate the appropriate execution of nondisclosure agreements on behalf of the Company.
Even after a nondisclosure agreement is in place, you should accept only the information that is necessary or appropriate to accomplish the purpose of receiving it, such as a decision on whether to proceed to negotiate a deal. If more detailed or extensive information is offered and it is not necessary or appropriate for your immediate purposes, it should be refused. If any such information is inadvertently received, it should be transferred to the Legal Department for appropriate disposition.
Once the Company has received nonpublic information, you should use all reasonable efforts to:
Industrial espionage
You may not unlawfully obtain or use the materials, products, intellectual property, proprietary, or nonpublic information or other assets of anyone, including suppliers, customers, business partners, and competitors. You may not coerce or improperly induce past or present employees of other companies to disclose proprietary or nonpublic information of their former or other employers.
Free and fair competition
It is our policy to lawfully compete in the marketplace. Our commitment to fairness includes respecting the rights of our competitors to compete lawfully in the marketplace and abiding by all applicable laws in the course of competing.
Most countries have well-developed bodies of law designed to encourage and protect free and fair competition. These laws are broad and far-reaching and regulate the Company's relationships with its distributors, resellers, suppliers, and customers. Competition laws generally address the following areas: pricing practices (including predatory pricing, price fixing, and price discrimination), discounting, terms of sale, credit terms, promotional allowances, secret rebates, exclusive dealerships or distributorships, product bundling, restrictions on carrying competing products, termination, and many other practices.
Competition laws also govern, usually quite strictly, relationships between the Company and its competitors. Collusion among competitors is illegal, and the consequences of a violation are severe. You must not enter into an agreement or understanding, written or oral, express or implied, with any competitor concerning prices, discounts or other terms or conditions of sale; profits or profit margins; costs; allocation of product, customers, markets or territories; limitations on production or supply; boycotts of customers or suppliers; or bids or the intent to bid, or even discuss or exchange information on these subjects.
The Company is committed to obeying both the letter and spirit of these laws, which are often referred to as antitrust, consumer protection, competition or unfair competition laws. Although the spirit of these laws is straightforward, their application to particular situations can be quite complex. To ensure that the Company complies fully with these laws, you should have a basic knowledge of them and should promptly involve our Legal Department when questionable situations arise.

WORKING WITH GOVERNMENTSOverview
Special rules govern our business and other dealings with governments. Employees, agents, and contractors of the Company should use all reasonable efforts to comply with all applicable laws and regulations governing contact and dealings with governments, government employees, and public officials. If you deal with governments, government employees, or public officials, you should undertake to understand the special rules that apply. If you have any questions concerning government relations, you should contact the Legal Department.
Government contracts
You should use all reasonable efforts to comply with all relevant laws and regulations that apply to government contracting. You should refer all contracts with any governmental entity to the Legal Department for review and approval.
Requests by regulatory authorities
You must cooperate with appropriate government inquiries and investigations in accordance with law. It is important, however, to protect the legal rights of the Company with respect to its nonpublic information. All government requests (other than from taxing authorities) for Company information, documents, or investigative interviews should be referred to the Legal Department, and requests from taxing authorities should be referred to the Finance Department. You should work with the Legal Department in responding to requests by regulatory authorities to ensure adequate and complete responses and to avoid improper disclosure of attorney-client privileged materials, trade secret information, or other nonpublic information. This policy should not be construed to prevent an employee from disclosing information to a government or law enforcement agency, where the employee has reasonable cause to believe that the information discloses a violation of, or noncompliance with, a state or federal statute or regulation.
Improper payments to government officials
You may not offer any payment or business amenity to a public official or a government employee if doing so could reasonably be construed as having any connection with the Company's business, even if it has a nominal value or no value at all. You should be aware that what may be permissible in dealings with commercial businesses may be deemed illegal and possibly criminal in dealings with the government. You should contact the Legal Department for guidance.
Whether you are located in the United States or abroad, you are also responsible for fully complying with the Foreign Corrupt Practices Act. The Foreign Corrupt Practices Act makes it illegal to offer, pay, promise to pay, or authorize to pay any money, gift or other item of value to any foreign official, political party, or candidate to assist the Company or another to obtain or retain business. All managers and supervisory personnel are expected to monitor continued compliance with the Foreign Corrupt Practices Act.
Political contributions
The Company reserves the right to communicate its position on important issues to elected representatives and other government officials. It is the Company's policy to comply fully with all local, state, federal, foreign, and other applicable laws, rules and regulations regarding political contributions. The Company's assetsincluding Company funds, employees' work time and Company premises and equipmentmust not be used for, or be contributed to, political campaigns or political activities under any circumstances without prior written approval of the Company's Legal Department.
Lobbying
You must obtain approval from the Legal Department for any work activity that requires direct or indirect lobbying communication with any member or employee of a legislative or administrative body or with any government official or employee in the formulation of legislation, regulations or other regulatory action. Work activity covered by this policy includes meetings with legislators or members of their staffs or with executive branch officials on behalf of the Company. Preparation, research, coordination with third parties and other background activities that are done in support of such lobbying communication are also covered by this policy even if the communication ultimately is not made.
Trade restrictions
A number of countries maintain controls on the destinations to which products or software may be exported. Some of the strictest export controls are maintained by the United States against countries that the United States government considers unfriendly or as supporting international terrorism. The U.S. regulations are complex and apply both to deemed exports from the United States and to deemed exports of products from other countries when those products contain U.S.-origin components or technology. Software created in the United States is subject to these regulations even if duplicated and packaged abroad. In some circumstances, an oral presentation containing technical data made to foreign nationals in the United States or access by foreign nationals to certain technology may constitute a controlled export. The Legal Department can provide you with guidance on which countries are prohibited destinations for Company products or whether a proposed technical presentation or the provision of controlled technology to foreign nationals may require a U.S. government license.

PROCEDURAL MATTERSDistribution
All employees and directors will receive a copy of this Code at the time they join the Company, or become a director, and will receive periodic updates. Agents and contractors should also be provided with a copy of the Code.

All employees and directors must sign an acknowledgment form confirming that they have read the Code and that they understand and agree to comply with its provisions. Signed acknowledgment forms will be kept by the Company. Failure to read the Code or to sign an acknowledgement form does not excuse any person from the terms of the Code.
Approvals and waivers
Except as otherwise provided in the Code, the Board of Directors or its designated committee must review and approve any matters requiring special permission under the Code for a member of the Board of Directors or an executive officer. Except as otherwise provided in the Code, the Chief Financial Officer and the Legal Department must review and approve any matters requiring special permission under the Code for any other employee, agent, or contractor.
Any waiver of any provision of this Code for a member of the Board of Directors or an executive officer must be approved in writing by the Board of Directors or its designated committee and promptly disclosed to the Disclosure Committee, along with the reasons for the waiver, to the extent required by law or regulation. Any waiver of any provision of this Code with respect to any other employee, agent or contractor must be approved in writing by the Chief Financial Officer and the Legal Department.
Copies of approvals and waivers will be retained by the Company.
Reporting violations
You should promptly report violations or suspected violations of this Code to the Legal Department. If your situation requires that your identity be kept secret, your anonymity will be preserved to the greatest extent reasonably possible. If you wish to remain anonymous, please utilize Trubion's third-party reporting agency as specified in the Trubion Whistleblower Policy. If you make an anonymous report, please provide as much detail as possible, including copies of any documents that you believe may be relevant to the issue.
If your concerns relate to accounting, internal controls or auditing matters, or if the Legal Department is implicated in any violation or suspected violation, you may also contact the Audit Committee of the Board of Directors as detailed in the Whistleblower Policy.
Reprisals, threats, retribution, or retaliation against any person who has in good faith reported a violation or a suspected violation of law, this Code, or other Company policies, or against any person who is assisting in good faith in any investigation or process with respect to such a violation, is prohibited.
Investigations
The Board of Directors or its designated committee will be responsible for investigating violations and determining appropriate disciplinary action for matters involving members of the Board of Directors or executive officers. The Board of Directors or its designated committee may designate others to conduct or manage investigations on its behalf and recommend disciplinary action.
Subject to the general authority of the Board of Directors to administer this Code, the Company's Legal Department will be responsible for investigating violations and determining with the Human Resources Department appropriate disciplinary action for other employees, agents and contractors. The Legal Department may designate others to conduct or manage investigations on its behalf and recommend disciplinary action. The Legal Department will periodically report any Code violations and the corrective actions taken to the Board of Directors or its designated committee. The Board of Directors reserves the right to investigate violations and determine appropriate disciplinary action on its own or to designate others to do so in place of, or in addition to, the Legal Department.
The Company will promptly investigate any suspected violations. If it is determined that evidence of a violation exists, the individual subject to investigation will be notified. The subject of an investigation will have an opportunity to respond to any allegations made against him or her. A person suspected of violating the Code may be suspended with or without pay while an investigation is conducted. The Company will follow local grievance procedures in jurisdictions where such procedures apply.
Disciplinary action
The Company will take appropriate action against any employee, agent, or contractor whose actions are found to violate the Code. Disciplinary actions may include, at the Company's sole discretion, oral or written reprimand, suspension, or immediate termination of employment or business relationship, or any other disciplinary action or combination of disciplinary actions as deemed appropriate to the circumstances. A record of the disciplinary action will be retained in the employee's personnel file. In determining what disciplinary action is appropriate in a particular case, the Company will take into account all relevant information, including the nature and severity of the violation, any history of warnings and violations, whether the violation appears to have been intentional or inadvertent, and whether the violator reported his or her own misconduct. The Company will strive to enforce the Code in a consistent manner while accounting for all relevant information. An alleged violator may make a written request for reconsideration within 14 days of notification of the final disciplinary decision. Where the Company has suffered a loss, it may pursue its remedies against the individuals or entities responsible. Certain violations of this Code may also be subject to civil or criminal prosecution by governmental authorities and others. Where laws have been violated, the Company will report violators to the appropriate authorities.
Self-Assessment
The Company shall conduct periodic self-assessments of the efficacy of this Code and the Company's Whistleblower Policy with appropriate questionnaires.
