SPECIAL MEETING OF STOCKHOLDERS
YOUR VOTE IS VERY IMPORTANT
 
Dear stockholder of Ciphergen Biosystems, Inc.:
 
The proxy statement attached to this letter provides you with information about the special meeting of Ciphergen’s stockholders and the proposals to be considered at the special meeting. We encourage you to read the entire proxy statement carefully. The proposal for which we are asking your approval is critical to focusing our efforts on building a dynamic specialty diagnostics business with a streamlined financial and organizational structure as well as the technical and managerial resources to address what we believe is a substantial opportunity. The board of directors and management of Ciphergen ask that you consider the following proposals.
 
Most importantly, you are asked to approve the sale of Ciphergen’s proteomics instrument business, which includes Ciphergen’s surface enhanced laser desorption/ionization, or SELDI, technology, ProteinChip® Arrays and accompanying software to BioRad Laboratories, Inc. pursuant to an asset sale. Ciphergen will retain rights to the clinical diagnostics market and will continue to develop the science to build this business. Upon stockholder approval of this transaction and completion of the sale, Ciphergen will be paid up to $20 million in cash by Bio-Rad, on the terms and subject to adjustment as described in the attached proxy statement. In addition, Bio-Rad will be making a $3 million equity investment in Ciphergen.
 
Stockholders of Ciphergen will be asked, at the special meeting of Ciphergen’s stockholders, to approve the asset sale and a proposal to grant discretionary authority to adjourn or postpone the Ciphergen special meeting to another time or place for the purpose of soliciting additional proxies. The board of directors of Ciphergen recommends that Ciphergen’s stockholders vote FOR approval of the sale of assets used in our proteomics instrument business and the adjournment proposal.
 
The date, time and place of the special meeting to consider and vote upon the proposals are as follows:
Thursday, October 26, 2006
2:00 p.m., local time
Ciphergen Biosystems, Inc.
6611 Dumbarton Circle
Fremont, California 94555
 
Your vote is very important. Whether or not you plan to attend the special meeting, if you are a holder of Ciphergen common stock, please take the time to vote by completing, signing, dating and mailing the enclosed proxy card to us so your shares are represented at the special meeting. If you do not vote, it will have the same effect as a vote against the asset sale to Bio-Rad and the adjournment proposal.
 
-s- Gail S. Page
 
Gail S. Page
President and Chief Executive Officer
Ciphergen Biosystems, Inc.
 
The proxy statement is dated September 28, 2006, and is first being mailed to stockholders of Ciphergen on or about September 28, 2006.

NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
To Be Held on Thursday, October 26, 2006
 
To our stockholders:
 
NOTICE IS HEREBY GIVEN that a special meeting of stockholders of Ciphergen Biosystems, Inc., a Delaware corporation, will be held on Thursday, October 26, 2006, at 2:00 p.m., local time, at Ciphergen’s headquarters located at 6611 Dumbarton Circle, Fremont, California: Your vote is very important. Please take a moment to read this letter in an effort to help Ciphergen to avoid the added expense of further solicitation. The proposals to be considered at the special meeting of stockholders are as follows
 
1. To consider and vote upon a proposal to approve the proposed sale of the assets used in our proteomics business, referred to as our research tools business, to Bio-Rad Laboratories, Inc. pursuant to the asset purchase agreement attached as Annex A to the accompanying proxy statement.
 
2. To consider and vote upon a proposal to grant discretionary authority to adjourn or postpone the Ciphergen special meeting to another time or place for the purpose of soliciting additional proxies.
 
3. To transact such other business as may properly come before the Ciphergen special meeting and any adjournments thereof.
 
The foregoing items of business are more fully described in the proxy statement accompanying this notice, which you are encouraged to read in its entirety. The board of directors of Ciphergen has fixed the close of business on September 15, 2006, as the record date for the determination of stockholders entitled to notice of, and to vote at, the special meeting and any adjournment or postponement thereof. Only holders of record of shares of Ciphergen common stock at the close of business on the record date are entitled to notice of, and to vote at, the special meeting or any adjournment or postponement of it. At the close of business on the record date, Ciphergen had outstanding and entitled to vote 36,075,017 shares of common stock.
 
Your vote is important. The affirmative vote of the holders of a majority of the outstanding shares of Ciphergen common stock is required to approve the proposed asset sale. The affirmative vote of a majority of the votes cast is required to approve the adjournment proposal. Even if you plan to attend the special meeting in person, we request that you complete, sign, date and return the enclosed proxy to ensure that your shares will be represented at the special meeting if you are unable to attend. If you fail to return your proxy card, the effect will be that your shares will not be counted for purposes of determining whether a quorum is present at the Ciphergen special meeting, but will effectively be counted as a vote against the proposed asset sale and other matters. If you do attend the special meeting and wish to vote in person, you may withdraw your proxy and vote in person.
 
The Ciphergen board of directors recommends that you vote “FOR” the asset sale to Bio-Rad and other matters as described in the proxy.
 
By Order of the Board of Directors,

If you vote by signing and returning the enclosed proxy card, the individual named as proxy on the card may vote your shares of common stock, in their discretion, on any other matter requiring a stockholder vote that comes before the meeting.
 
You will receive more than one proxy statement and proxy card or voting instruction form if your shares of common stock are held through more than one account (i.e., through different names or different brokers or nominees). Each proxy card or voting instruction form only covers those shares of common stock held in the applicable account. If you hold shares of common stock in more than one account, you have to provide voting instructions for all your accounts in order to vote all of your shares of common stock.

Description of the Proposed Asset Sale
 
On August 14, 2006, we entered into an asset purchase agreement with Bio-Rad. Under the terms of the asset purchase agreement, we have agreed to sell our assets used in connection with our research tools business to Bio-Rad in exchange for a total purchase price of up to $20 million in cash for the assets and the assumption by Bio-Rad of certain liabilities of our research tools business. At the closing of the asset sale, we will receive $16 million in cash and an additional $2 million will be put into an escrow account for at least three years following the close of the asset sale, to secure our indemnification obligations under the asset purchase agreement. Bio-Rad will retain an additional $2 million pending the issuance of a reexamination certificate of U.S. Patent No. 6,734,022, referred to as our SELDI patent, confirming the patentability of all of the claims as originally issued in such patent or claims of equivalent scope.
 
In connection with the proposed asset sale, we also agreed to enter into a manufacture and supply agreement and a cross license agreement with Bio-Rad upon the closing of the proposed asset sale. Under the terms of the manufacture and supply agreement, Bio-Rad has agreed to supply us with the instrumentation, chips and supplies previously manufactured by us in the research tools business, which are necessary to continue the development of our specialty diagnostics business. Under the terms of the cross license agreement, for a five-year period we will have an exclusive license to commercialize the intellectual property being transferred to Bio-Rad in the clinical diagnostics market.
 
See “Proposal No. 1 — Proposal to Approve the Asset Sale to Bio-Rad — The Asset Purchase Agreement,” “Proposal No. 1 — Proposal to Approve the Asset Sale to Bio-Rad — Ancillary Agreements.”
 
Our Reasons for the Proposed Asset Sale
 
The proposed asset sale will enable us to realize immediately the value of our research tools business in cash, thereby increasing our ability to finance our specialty diagnostics business, as described in Annex B — New Business Strategy.

See “Proposal No. 1 — Proposal to Approve the Asset Sale to Bio-Rad — Ciphergen’s Reasons for the Asset Sale.”
 
Recommendation of Our Board of Directors Regarding the Proposed Asset Sale
 
At a meeting on August 14, 2006, our board of directors unanimously determined that the proposed asset sale is in the best interest of Ciphergen and our shareholders and unanimously approved the proposed asset sale. Our board of directors recommends that you vote “FOR” the approval of the proposed asset sale.
 
Opinion of our Financial Advisor
 
Oppenheimer & Co. Inc. delivered its oral opinion to our board of directors on August 14, 2006, subsequently confirmed in writing as of August 14, 2006, to the effect that and based upon and subject to the various assumptions set forth in the written opinion, the consideration to be paid by Bio-Rad in the asset sale was fair, from a financial point of view, to us.
 
The full text of the written opinion of Oppenheimer, dated August 14, 2006, which sets forth the assumptions made, procedures followed, other matters considered and limitations on the review undertaken by Oppenheimer in connection with the opinion, is attached as Annex C to this proxy statement and is incorporated in this proxy statement by reference. We encourage you to read the opinion in its entirety. Oppenheimer provided its opinion for the information and assistance of our board of directors in connection with its consideration of the asset sale. The Oppenheimer opinion is not a recommendation as to how any holder of our common stock should vote with respect to the asset sale.
 
See “Proposal No. 1 — Proposal to Approve the Asset Sale to Bio-Rad — Opinion of our Financial Advisor.”
 
Interests of Our Directors and Executive Officers in the Proposed Asset Sale
 
In considering the recommendation of our board of directors with respect to the proposed asset sale, our stockholders should be aware that certain of our executive officers may have an interest in the sale of our assets that could differ from the interests of our stockholders.
 
We entered into an employment agreement, dated December 31, 2005, with Gail S. Page, our president and chief executive officer and a member of our board of directors. In relevant part, the agreement provides that if Ciphergen undergoes a change of control and within 12 months afterwards Ms. Page’s employment is terminated or constructively terminated without cause, she will receive severance pay and medical benefits for a period of 12 months and all of the options granted to her will immediately vest.
 
We entered into an employment agreement, dated January 15, 2005, with James P. Merryweather, PhD, our executive vice president, sales and marketing. In relevant part, the agreement provides that if Ciphergen undergoes a change of control and within 12 months afterwards Dr. Merryweather’s employment is terminated or constructively terminated without cause, he will receive severance pay and medical benefits for a period of 12 months and all of the options granted to him will immediately vest.
 
As used in each of these agreements, (i) a “change of control” includes the sale or other disposition of all or substantially all of our company’s assets; (ii) a “constructive termination” includes any purported termination of the employee which is not effected for “cause” or for which the grounds relied upon are not valid; and (iii) “cause” includes, among other things, termination of employment due to the employee’s willful, repeated failure substantially to perform his or her duties, a willful act by the employee that constitutes gross misconduct and that is injurious to our company and conviction of a felony crime. It is our position that the asset sale to Bio-Rad does not constitute a change in control as defined in these agreements. Should the asset sale be deemed to be a change of control, and the aforementioned employees are terminated within twelve months of the proposed asset sale for reasons other than for cause, we would be required to provide the severance pay and benefits described above.

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING
 
Q: What proposals will be voted on at the special meeting?
 
A: The following proposals will be voted on at the special meeting:
 
  •  The first proposal to be voted on is a proposal to approve the proposed sale of the assets of our research tools business to Bio-Rad Laboratories, Inc. pursuant to the terms of the asset purchase agreement attached as Annex A to this proxy statement. See “Proposal No. 1 — Proposal to Approve the Asset Sale to Bio-Rad.”
 
  •  The second proposal to be voted on is a proposal to grant discretionary authority to adjourn or postpone the Ciphergen special meeting to another time or place for the purpose of soliciting additional proxies, which we refer to in this proxy statement as the Ciphergen adjournment proposal. See “Proposal No. 2 — Proposal to Grant Authority to Adjourn or Postpone the Special Meeting.”
 
Q: Why are you selling the assets of the research tools business?
 
A: We are selling the assets of the research tools business so that we can focus on developing our emerging specialty diagnostics business. This diagnostics focus stems from our core competency, which involves biomarker discovery derived from a suite of tools for protein separation combined with rigorous study design.
 
Q: What will you do with the proceeds from the sale of the assets of the research tools business?
 
A: We will use the proceeds of the asset sale to support the development of our emerging specialty diagnostics business.
 
Q: Who is the purchaser in the proposed asset sale?
 
A: The purchaser is Bio-Rad Laboratories, Inc. Bio-Rad is a public company headquartered in Hercules, California, which serves more than 70,000 research and industry customers worldwide through its global network of operations. Bio-Rad employs over 5,000 people globally and had revenues of $1.1 billion in 2005.
 
Q: What is the purchase price for our assets?
 
A: Bio-Rad has agreed to pay us a total purchase price of up to $20 million in cash for the assets and to assume certain liabilities of our research tools business. At the closing of the asset sale, we will receive $16 million in cash and an additional $2 million will be put into an escrow account for at least three years after the close of the asset sale, to secure our indemnification obligations under the asset purchase agreement. Bio-Rad will retain an additional $2 million pending the issuance of a reexamination certificate of a specific patent, as more fully discussed below in this proxy statement.
 
Q: What will happen if the asset sale to Bio-Rad is approved?
 
A: If the asset sale to Bio-Rad is approved, we will complete the sale of the assets to Bio-Rad in accordance with the terms of and subject to satisfaction of the closing conditions set forth in the asset purchase agreement. We anticipate that the transaction will close shortly after the special meeting. Following this sale, we will focus on developing our emerging specialty diagnostics business.
 
Q: What will happen if the asset sale to Bio-Rad is not approved?
 
A: If our stockholders do not approve the sale of the research tools business, we will continue to operate the research tools business and continue to explore strategic alternatives. The failure of the sale of the research tools business to be consummated could adversely effect our research tools business through loss of customers, loss of employees and other factors.
 
Q: Do I have any appraisal rights in connection with the asset sale?
 
A: No. Our stockholders do not have appraisal rights in connection with the asset sale.

Q What is our board of directors’ recommendation with respect to the proposals to be considered at the special meeting?
 
A: Our board of directors recommends a vote “FOR” approval of the asset sale and the grant of discretionary authority to adjourn or postpone the special meeting.
 
Q: What vote is required?
 
A: The affirmative vote of the holders of a majority of the outstanding shares of Ciphergen common stock is required to approve the proposed asset sale. The affirmative vote of a majority of the votes cast is required to approve the adjournment proposal.
 
Q: What do I need to do now?
 
A: After carefully reading and considering the information contained in this proxy statement, you should complete and sign your proxy and return it in the enclosed return envelope as soon as possible so that your shares may be represented at the meeting. A majority of shares entitled to vote must be represented at the meeting to enable us to conduct business at the meeting. See “Information About the Special Meeting.”
 
Q: Can I change my vote after I have mailed my signed proxy?
 
A: Yes. You can change your vote in one of three ways at any time before proxies are voted at the meeting. First, you can send a written notice via registered mail to our president and chief executive officer, Gail S. Page, at our executive offices, stating that you would like to revoke your proxy. Second, you can complete and submit a new proxy. If you choose either of these two methods, you must submit the notice of revocation or the new proxy to us before the special meeting. Third, you can attend the meeting and vote in person. See “Information About the Special Meeting — Revocability of Proxies.”
 
Q: If my Ciphergen shares are held in “street name” by my broker, will the broker vote the shares on my behalf?
 
A: A broker will vote Ciphergen shares only if the holder of these shares provides the broker with instructions on how to vote. Shares held in “street name” by brokers or nominees who indicate on their proxies that they do not have discretionary authority to vote such shares as to a particular matter, referred to as “broker non-votes,” will not be voted in favor of such matter. The proposal to approve the proposed asset sale requires the affirmative vote of a majority of our outstanding shares in order for the sale to be approved by our stockholders. Accordingly, broker non-votes will have the effect of a vote against the proposed asset sale. The proposal to grant discretionary authority to adjourn or postpone the special meeting requires the affirmative vote of a majority of the votes cast at the special meeting, so a broker non-vote will have no effect on the outcome of that proposal. We encourage all stockholders whose shares are held in street name to provide their brokers with instructions on how to vote. See “Information About the Special Meeting — Quorum; Abstentions; Broker Non-Votes.”
 
Q: Can I still sell my shares of Ciphergen common stock?
 
A: Yes. Our common stock is currently traded on The Nasdaq Capital Market.
 
Q: Who can help answer my questions?
 
A: If you have any questions about the special meeting or the proposals to be voted on at the special meeting, or if you need additional copies of this proxy statement or copies of any of our public filings referred to in this proxy statement, you should contact our Investor Relations department at 510-505-2233. Our public filings can also be accessed at the Securities and Exchange Commission’s web site at www.sec.gov.

Revocability of Proxies
 
Execution of a proxy will not in any way affect a stockholder’s right to attend the special meeting and vote in person. Any stockholder giving a proxy has the right to revoke it in one of three ways:
 
  •  you can send a written notice via registered mail to our president and chief executive officer, Gail S. Page, at our executive offices, stating that you would like to revoke your proxy;
 
  •  you can complete and submit a new proxy; or
 
  •  you can attend the meeting and vote in person.
 
If you choose either of the first two methods, you must submit the notice of revocation or the new proxy to us before the special meeting.
 
Quorum; Abstentions; Broker Non-Votes
 
The presence in person or by proxy of the holders of at least a majority of the outstanding shares of common stock entitled to vote at the special meeting is necessary to establish a quorum for the transaction of business. Votes cast by proxy or in person at the special meeting will be tabulated by the inspector of elections. The inspector of elections will also determine whether or not a quorum is present. Abstentions are included in the number of shares present or represented at the special meeting.
 
Shares held in “street name” by brokers or nominees who indicate on their proxies that they do not have discretionary authority to vote such shares as to a particular matter, referred to as “broker non-votes,” and shares which abstain from voting as to a particular matter, will not be voted in favor of such matters. The proposal to approve the asset sale to Bio-Rad requires the affirmative vote of a majority of our outstanding shares in order for the sale to be approved by our stockholders. Accordingly, abstentions and broker non-votes will have the effect of a vote against the proposal to approve the asset sale to Bio-Rad.
 
Adjournment and Postponement
 
Whether or not a quorum is represented at a stockholder meeting, our bylaws permit the stockholders present in person or represented by proxy to adjourn the meeting from time to time by the vote of the majority of the shares represented at that meeting without notice other than announcement at the meeting, until a quorum is present or represented. The Delaware General Corporation Law requires that if a meeting is adjourned for more than 30 days after the date for which the meeting was originally noticed, or if a new record date is fixed for the adjourned meeting, written notice of the place, date and time of the adjourned meeting must be given to the stockholders.
 
Solicitation of Proxies
 
We will bear the cost of soliciting proxies.  In addition, we may reimburse brokerage firms and other persons representing beneficial owners of shares for their expenses in forwarding solicitation material to such beneficial owners. Solicitation of proxies by mail may be supplemented by telephone, facsimile, e-mail or personal solicitation by our directors, officers or regular employees. We will not pay any additional compensation to such persons for such services.

PROPOSAL NO. 1 — PROPOSAL TO APPROVE THE ASSET SALE TO BIO-RAD
 
This section of the proxy statement describes material aspects of the proposed asset sale to Bio-Rad, including the asset purchase agreement attached as Annex A to this proxy statement. This summary may not contain all of the information that is important to you. You should carefully read this proxy statement, including the full text of the asset purchase agreement, for a more complete understanding of the asset sale.
 
Background of the Asset Sale
 
We have incurred operating losses and negative cash flows since our inception, and revenues from the research tools business have declined from $43.6 million in 2003 to $40.2 million in 2004 to $27.2 million in 2005. However, during that time, we have discovered and filed patents on biomarkers and patterns of biomarkers that can potentially be developed into specialty diagnostic tests to improve patient care. In July 2005, we entered into a strategic alliance agreement with Quest Diagnostics Incorporated pursuant to which the parties have agreed to develop and commercialize up to three diagnostics tests based on Ciphergen’s proprietary SELDI technology during a three year period.
 
In the fourth quarter of 2005, we held a series of discussions with Bio-Rad about their possible interest in our designing a customized version of our PCS 4000 ProteinChip instrument for a particular application which would complement Bio-Rad’s existing product lines sold to life science researchers. As a result of a series of meetings in the fourth quarter, criteria were drawn up for the specifications for such an instrument and we began to develop preliminary data for this application. This was followed up by a meeting of members of the parties’ respective scientific and business staffs at our Fremont facility in December 2005.
 
In December 2005, there were a series of significant changes in our management team. Following the retirement of Dr. William E. Rich, Gail S. Page became president and chief executive officer. Ms. Page had joined Ciphergen in early 2005 as executive vice president and president of our diagnostics division and, in mid-2005, Ms. Page was promoted to president and chief operating officer.
 
In January 2006, there was a strategic planning meeting of the new management team where the business prospects of the research tools business and our diagnostics business, as well as the financial picture of Ciphergen, were discussed at length. At this meeting, it was the consensus view of management that our greatest opportunity for future value creation lay in focusing our resources on the emerging specialty diagnostics business. While we believe our ProteinChip platform is a powerful research tool, it is only one of a variety of tools needed by proteomics researchers today. We currently offer a single instrument, while our competitors offer a suite of instruments and related products. Therefore, we determined that it would be in our stockholders’ best long-term interest to focus on the commercialization of our biomarker capability in the specialty diagnostics market, and that strategic options regarding our research tools business, including the sale of the research tools business to provide capital for our diagnostics efforts, should be explored.
 
In January 2006, Mr. Norman Schwartz, chief executive officer, and Mr. Todd Morrill, director, acquisitions and business development for Bio-Rad, met at our headquarters with Gail Page and Dr. Simon Shorter, vice president of corporate business development. At this meeting we presented a business plan which included a potential strategic transition of our business from manufacturing and selling instruments, consumables and software, into a business developing and selling diagnostic products. Discussions moved from the possibility

of our building a customized instrument to be resold by Bio-Rad to the potential acquisition by Bio-Rad of our entire research tools business.
 
On January 26, 2006, members of Bio-Rad’s acquisitions and business development group visited our headquarters and the first of a series of documents including Ciphergen’s financial information and intellectual property were provided pursuant to a confidentiality agreement.
 
On February 8, 2006, there was a meeting of our board of directors. At this meeting, plans for the potential divestiture of the research tools business were discussed and an update on all the discussions to date was presented. This update included a summary of discussions with two other entities, referred to here as Party A and Party B, described below, as well as the status of discussions with Bio-Rad. It was stated at this meeting that Bio-Rad had made a non-binding, verbal offer to purchase the research tools business for up to $20 million.
 
Initial discussions about a possible business arrangement with Party A began in October 2005. This was followed by a conference call with our management in January 2006 and a site visit to our headquarters in February 2006. Detailed financial information, technical data, intellectual property and other due diligence materials were provided to Party A. Following these discussions, a non-binding indication of interest was made by Party A to buy only the consumables portion of our research tools business. This offer was deemed to be insufficient and all further conversations with this party ceased at that time.
 
In March 2006, a meeting took place between our chief executive officer and our executive chairman of the board and the chief executive officer of Party B, in which we provided a business update and the nature of our strategic transition plans were described. Following this meeting, Party B verbally described interest in an arrangement whereby Party B would manufacture a mass spectrometer for sale by us. Since this type of transaction failed to accomplish our broader strategic goals, no further discussion with this party took place.
 
During this period, two additional companies were approached about potentially acquiring our research tools business but neither party expressed interest.
 
In summary, there were discussions with five companies. Three of these had significant but varied interests, and the management team determined that further discussions with Bio-Rad offered the greatest opportunity for future value creation.
 
Throughout March and April 2006, further discussions took place with Bio-Rad and, on April 12, 2006, our board of directors had a meeting at which it was agreed that we should proceed with the offer from Bio-Rad and also established that there was no continuing or acceptable interest from other parties at this time.
 
On May 12, 2006, Ciphergen and Bio-Rad signed a nonbinding letter of intent, which included binding confidentiality and standstill provisions. These letters were approved by a telephonic meeting of our board on May 12, 2006. Following execution of these agreements, we and our outside counsel began negotiating the terms of a definitive agreement with Bio-Rad. Following discussions among our management and further discussions with Bio-Rad regarding our requirement to retain the right to continue to conduct business in the clinical diagnostics area, Bio-Rad indicated a willingness to consider purchasing the assets of our research tools business for up to $20 million, as well as to make an equity investment of up to $3 million in Ciphergen.
 
Subsequently, multiple due diligence meetings between the parties took place. On May 23, 2006, Mr. Todd Morrill and other members of Bio-Rad management conducted an on-site visit to our headquarters. This meeting was followed by a subsequent on-site due diligence session on June 2, 2006. On June 13, 2006, a third on-site due diligence visit took place in which Mr. Todd Morrill and members of the Bio-Rad legal, financial and technical team spent another day at our headquarters.
 
During the week of June 12, 2006, Mr. Todd Morrill and Mr. Tom Slyker, new technologies marketing manager, of Bio-Rad accompanied Dr. Jim Merryweather, executive vice president of sales and marketing, and Dr. Simon Shorter on visits to our customers on the east coast of the United States and to our Biomarker Discovery Center® laboratory in Malvern, Pennsylvania. During the week of June 26, 2006, a similar due diligence visit was conducted by Mr. Morrill and Drs. Merryweather and Shorter, with visits to our Guildford, UK and Copenhagen, Denmark, Biomarker Discovery Center laboratories.

Between July 1 and August 13, 2006, we and Bio-Rad and our respective legal counsel negotiated the terms and conditions of the asset purchase agreement, including the specific assets and liabilities to be transferred, the closing conditions and the terms under which we could consider alternative proposals to the asset sale to Bio-Rad, termination, termination fees and the indemnification provisions and the terms of the stock sale, manufacture and supply agreement, cross license agreement and other ancillary agreements.
 
On August 14, 2006, our board of directors held a telephonic meeting. Ms. Gail Page gave an overview of the terms of the proposed transaction with Bio-Rad. Our outside legal counsel then reviewed with our board their fiduciary duties in connection with the proposed transaction with Bio-Rad and reviewed with our board the terms and conditions of the proposed asset purchase agreement, stock purchase agreement and ancillary agreements negotiated with Bio-Rad, including the termination, termination fee and indemnification provisions.
 
Also at this time, our board of directors reviewed the oral opinion and proposed form of opinion letter from Oppenheimer & Co., to the effect that and based upon and subject to the various assumptions set forth in the written opinion, the consideration to be paid by Bio-Rad in the asset sale was fair, from a financial point of view, to us. See “Proposal No. 1 — Proposal to Approve the Asset Sale to Bio-Rad — Opinion of our Financial Advisor.” The analyses supplied by Oppenheimer and its opinion were among several factors taken into consideration by our board of directors in making its decision to enter into the asset sale to Bio-Rad, and should not be considered as determinative of such decision. After extensive discussion and deliberation, our board of directors approved the asset purchase agreement and the transactions contemplated by the asset purchase agreement, resolved to recommend that our stockholders approve the asset purchase agreement, and authorized execution of the asset purchase agreement.
 
The parties executed the asset purchase agreement and issued a press release announcing the execution on August 14, 2006.
 
Use of Proceeds from the Proposed Asset Sale
 
If the proposed asset sale is completed, we currently intend to utilize the net proceeds to fund the development of our emerging specialty diagnostics business. We believe that there is a market opportunity in the discovery, development and commercialization of specialty diagnostic tests that help physicians manage their patients and that improve patient outcomes.
 
Ciphergen’s Reasons for the Asset Sale; Recommendation of the Board of Directors
 
Our board of directors considered a number of factors before recommending that our stockholders approve the proposed asset sale, including the following:
 
  •  that we had explored strategic alternatives, including discussions with alternative parties concerning the sale of Ciphergen’s research tools business, as described above;
 
  •  that we would require additional time and resources to locate and negotiate with any other potential purchasers for the assets, with no assurance that any such negotiations would be completed successfully, in a timely fashion, or at all;
 
  •  that the consideration offered by Bio-Rad for our research tools business represented what our management and board of directors believed was the offer that would result in higher value to our stockholders with greater certainty of timely consummation than any offer from any third party and would be paid substantially in cash;
 
  •  that certain of the ancillary agreements to the asset purchase agreement would still allow us to commercialize our biomarker technology in the specialty diagnostics market;
 
  •  the financial presentation of Oppenheimer on August 14, 2006 and the oral opinion of Oppenheimer delivered on August 14, 2006 to our board of directors, subsequently confirmed in writing as of August 14, 2006, to the effect that and based upon and subject to the various assumptions set forth in the written opinion, as of August 14, 2006, the consideration to be paid by Bio-Rad in the asset sale was fair, from a financial point of view, to us (the full text of the written opinion of Oppenheimer, which sets forth the assumptions

  made, procedures followed, other matters considered and limitations on the review undertaken by Oppenheimer in connection with the opinion, is attached as Annex C to this proxy statement and is incorporated into this proxy statement by reference);
 
  •  that we would be entitled to engage with third parties who make acquisition proposals under certain circumstances and that we would be entitled to terminate the asset purchase agreement, with the payment of a termination fee, to enter into an agreement for a superior proposal;
 
  •  that the value of our assets, particularly our intellectual property and certain contracts and customer relationships, would decline with the passage of time;
 
  •  our business and financial prospects if we were to continue the operation of our business as currently conducted;
 
  •  our financial condition, historical results of operations and business and strategic objectives, including the risks involved in achieving those objectives and the fact that we have incurred operating losses and negative cash flows from operations since our inception and we expect to continue to incur operating and net losses for the foreseeable future;
 
  •  that Bio-Rad would assume certain of our obligations; and
 
  •  the terms and conditions of the asset purchase agreement and the likely timing of closing of the asset sale to Bio-Rad.
 
In the course of its deliberations, our board of directors also considered, among other things, the following negative factors:
 
  •  risks and contingencies related to the announcement and pendency of the asset sale, including the likely impact of the asset sale on our employees, customers and partners and the expected effect of the asset sale on our existing relationships with third parties;
 
  •  the possibility that the asset sale will not be completed and the potential negative effect of public announcement of the asset sale in that event on our sales, operating results and our ability to retain key management and personnel;
 
  •  we will not benefit from any potential increase in the value of the research tools business;
 
  •  the conditions to Bio-Rad’s obligation to complete the asset sale and the right of Bio-Rad to terminate the asset purchase agreement under certain circumstances; and
 
  •  the interests that certain of our directors and executive officers may have with respect to the asset sale in addition to their interests as stockholders of Ciphergen generally as described in “Proposal No. 1 — Proposal to Approve the Asset Sale to Bio-Rad — Interests of our Directors and Executive Officers in the Asset Sale.”
 
The foregoing includes the material factors considered by our board of directors. In view of its many considerations, our board of directors did not quantify or otherwise assign relative weight to the specific factors considered. In addition, individual members of our board of directors may have given different weights to different factors. After weighing all of these considerations, our board of directors was unanimous in determining to approve the asset sale and to recommend that our stockholders approve the proposed asset sale to Bio-Rad.
 
Factors to be Considered by Stockholders in Deciding Whether to Approve the Asset Sale
 
You should carefully consider the following risk factors relating to the asset sale before you decide whether to vote to approve the asset sale proposal. You should also consider the other information in the proxy statement and the additional information in our other reports on file with the Securities and Exchange Commission.
 
There is no plan to distribute any of the proceeds of the asset sale to our stockholders.
 
We do not intend to distribute any portion of the proceeds from the asset sale to our stockholders. We currently intend to use the proceeds from the asset sale to fund and grow our diagnostics business. However, in light of the


12


Table of Contents

evolving nature of our diagnostics business, we cannot specify exactly how we will spend or invest the proceeds from the asset sale.
 
There is no guarantee of success in the specialty diagnostics market.
 
We believe that it is in our best interest to exit the research tools business and focus our resources on the specialty diagnostics market. However, to date, we have not developed any diagnostic products and can offer no assurance that we will be able to develop any diagnostic products or that we will succeed in commercializing any diagnostic products we do develop, or that we will be able to secure sufficient equity or debt financing necessary to sustain operations until our diagnostic products generate meaningful revenues. Even if we are able to complete the development and commercialization of diagnostic products, we cannot guarantee that we will achieve profitability or that the diagnostics business will prove successful. Immediately following the sale of our research tools business, our remaining business operations will be significantly smaller and we will not expect revenues until the successful development and commercialization of products in our diagnostics business.
 
Our research tools business is currently the only revenue generating portion of our operations. After the closing of the asset sale, the specialty diagnostics business will comprise our remaining business.
 
We will be dependent on Bio-Rad for the manufacture and supply of the ProteinChip platform tools necessary for the successful development and commercialization of diagnostic tests
 
We currently manufacture the ProteinChip instruments, arrays, and supplies utilized for biomarker discovery and the development of diagnostic tests. Following the completion of the asset purchase, Bio-Rad will be the sole supplier to us of these ProteinChip instruments, arrays, and supplies. Although Bio-Rad has agreed to manufacture and supply the ProteinChip instruments, arrays, and supplies for us pursuant to the manufacture and supply agreement, there can be no assurance Bio-Rad will manufacture such items meeting applicable specifications in the quantities and according to the schedule which we may require. In the event that Bio-Rad is unable to provide the instruments and ProteinChip arrays as required, under certain conditions we are allowed to manufacture these items ourselves or seek a third party supplier, but there is no guarantee that we will be able to find such a supplier, or that the cost of purchasing these items will be commercially reasonable. If we are not able to obtain the necessary ProteinChip instruments, arrays, and supplies, our ability to develop diagnostic products will be adversely affected.
 
Our strategic alliance with Quest Diagnostics may be negatively affected by the sale of the research tools business.
 
In July 2005, we entered into a strategic alliance with Quest Diagnostics with the goal of commercializing up to three diagnostic assays over a three year period. Pursuant to the strategic alliance agreement, we are responsible for selling ProteinChip instruments, arrays, and other supplies to Quest Diagnostics and to develop new versions of such products as may be required for Quest Diagnostics. Because Bio-Rad will be responsible for research and development and manufacture related to the ProteinChip platform following the asset sale, we will not be able directly to control whether Bio-Rad will devote sufficient attention and resources to the production and development of the ProteinChip platform. If we cannot provide sufficient ProteinChip instruments, arrays, and other supplies to Quest Diagnostics pursuant to the strategic alliance agreement, we may be in breach of our obligation to Quest Diagnostics and, even if we fulfill all our contractual obligations to Quest Diagnostics, it is possible that our relationship with Quest Diagnostics will be adversely affected by the sale of the research tools business to Bio-Rad, which could have an impact on our successful ability to commercialize our potential diagnostic tests.
 
The asset sale will expose us to contingent liabilities and we may not receive any of the contingent portion of the consideration to be paid by Bio-Rad.
 
Under the asset purchase agreement, we have agreed to indemnify Bio-Rad for any breaches of our representations, warranties and covenants contained in the asset purchase agreement, as well as for certain patent and other matters, up to a maximum amount of $20 million. $2 million of the purchase price will be held in escrow for at least three years following the completion of the asset sale and available to satisfy indemnification claims made by Bio-Rad against us. An additional $2 million of the purchase price will be held back by Bio-Rad pending the issuance of a reexamination certificate relating to one of our patents, referred to as the SELDI patent, and we have agreed to a maximum potential liability of $10 million with respect to the SELDI patent. Unless a


13


Table of Contents

reexamination certificate for the SELDI patent is issued which confirms the patentability of all of the claims as originally issued in that patent (or claims of equivalent scope), we will not receive the $2 million being held back by Bio-Rad. It is possible that, following the completion of the asset sale, we may receive significant indemnification claims by Bio-Rad, which may exceed the $2 million escrow amount, potentially resulting in liabilities to Ciphergen up to the $20 million cap. We also may receive indemnification claims relating to the SELDI patent, potentially up to the $10 million cap. The occurrence of any of these events could have a material adverse effect on our business following the completion of the asset sale. See “Proposal No. 1 — Proposal to Approve the Asset Sale to Bio-Rad — The Asset Purchase Agreement.”
 
We will continue to incur liabilities and expenses that will reduce the cash available to Ciphergen prior to the closing.
 
Liabilities and expenses from operations (such as operating costs, salaries, directors and officers insurance, payroll and local taxes and legal and accounting fees), including operation of our research tools business, will continue to be incurred as we seek to close the asset sale to Bio-Rad, reducing the amount of cash available for the diagnostics business.
 
The asset sale to Bio-Rad could cause the holders of our convertible promissory notes to demand immediate repayment of the notes.
 
Pursuant to the indenture agreement governing the terms of our outstanding convertible promissory notes, upon a change in control (as defined in the indenture), the debtholders may elect to require us to repurchase all or a portion of their notes at a premium over the face value of the notes. While it is our position that the asset sale to Bio-Rad does not constitute a change in control as defined in the indenture, the debtholders may disagree and seek to force us to repurchase some or all of their notes, which may result in costly litigation and a distraction for management. An entity which we believe holds $18.5 million in principal amount of our convertible promissory notes has advised us that they disagree with our position that the asset sale does not constitute a change of control as defined in the indenture. Such entity has indicated that it reserves its rights to the remedies set forth in the indenture, which include the right to have their notes repurchased at 105% of their principal amount in the event the asset sale is determined to be a change in control. In the event that we are required to repurchase notes, we may not have sufficient funds to do so nor be able to arrange for refinancing of the notes.
 
We may not be able to obtain necessary third party consents to the transfer of certain assets for closing of the asset sale.
 
In addition to other conditions that must be satisfied prior to closing the asset sale, we are obligated to obtain certain third party consents, including some of our clients, customers, and lessors. If we are unable to obtain these consents, the asset sale may not be consummated. The receipt of these consents depends upon parties other than us over which we have no control.
 
If we do not sell our research tools business, we will have difficulty sustaining operations over the long-term without significant amounts of new capital.
 
Ciphergen has incurred operating losses and negative cash flows since our inception, and revenues from the research tools business have declined from $43.6 million in 2003 to $40.2 million in 2004 to $27.2 million in 2005. There is no guarantee that, if the asset sale is not approved, we will be able to obtain additional capital to continue operation of the business through debt or equity financings.
 
If we do not sell our research tools business at this time its value may decrease.
 
The value of our assets, particularly our intellectual property and certain contracts and customer relationships, may decline in value with the passage of time. If we do not complete the sale of assets to Bio-Rad, there is no guarantee that, if and when we find another buyer for the research tools business, the assets will be valued by such buyer at the same amount as that offered by Bio-Rad.

Table of Contents

If we do not sell our research tools business to Bio-Rad as announced, it may negatively affect the price of our stock, relationships with our customers, and our ability to retain key management and personnel.
 
If we fail to complete the sale of the research tools business to Bio-Rad, it may be perceived in the market as a negative sign of the ability of Ciphergen to sustain its operations over the long term. This perception could negatively affect the price of Ciphergen’s stock, the willingness of customers to renew contracts, and the ability to retain employees.
 
Federal Income Tax Consequences to Us of the Proposed Asset Sale
 
As a result of the proposed asset sale, we will sell our research tools business to Bio-Rad in exchange for up to $20 million. This amount, plus the amount of liabilities assumed by Bio-Rad that are required to be capitalized for tax purposes, will be allocated among all of our assets that are sold to Bio-Rad. We will recognize gain or loss on each of the assets sold in an amount equal to the difference between the sales price allocated to that asset and our tax basis in such asset.
 
We do not believe the proposed asset sale will result in federal or state corporate income tax liability (including any alternative minimum tax liability), because we anticipate that any taxable gain with respect to a particular asset will be offset for income tax purposes by losses that we will recognize with respect to the sale of other assets as well as our operating losses, including losses from prior years. However, tax authorities may disagree with our determination of our available operating losses or our allocation of the purchase price among the assets sold, or our operating losses could be less than anticipated, which may increase our income tax liability as a result of the proposed asset sale.
 
Accounting Treatment of the Proposed Asset Sale
 
We will account for the proposed asset sale as a sale of assets and assumption of liabilities, in accordance with accounting principles generally accepted in the United States (GAAP). Upon the completion of the asset sale, we will recognize a financial reporting gain, if any, equal to the net proceeds (the sum of the purchase price received less the expenses relating to the asset sale) less the net book value of the assets purchased and the fair value of the indemnification liability retained.
 
Regulatory Approvals
 
No federal or state regulatory requirements must be complied with or approvals obtained as a condition of the proposed asset sale.
 
Appraisal Rights
 
Our stockholders have no appraisal rights in connection with the sale of assets to Bio-Rad.
 
Vote Required and Board of Directors Recommendation
 
The approval of the proposed asset sale to Bio-Rad requires the approval of a majority of the outstanding shares of our common stock.
 
Our board of directors believes that the proposed asset sale is in our best interests and the best interests of our stockholders and recommends a vote “FOR” the Ciphergen proposal to approve the asset sale.
 
Interests of Our Directors and Executive Officers in the Proposed Asset Sale
 
In considering the recommendation of our board of directors with respect to the proposed asset sale, our stockholders should be aware that certain of our executive officers may have an interest in the sale of our assets that could differ from the interests of our stockholders.
 
We entered into an employment agreement, dated December 31, 2005, with Gail S. Page, our president and chief executive officer and a member of our board of directors. In relevant part, the agreement provides that if Ciphergen undergoes a change of control and within 12 months afterwards Ms. Page’s employment is terminated or


15


Table of Contents

constructively terminated without cause, she will receive severance pay and medical benefits for a period of 12 months and all of the options granted to her will immediately vest.
 
We entered into an employment agreement, dated January 15, 2005, with James P. Merryweather, PhD, our executive vice president, sales and marketing. In relevant part, the agreement provides that if Ciphergen undergoes a change of control and within 12 months afterwards Dr. Merryweather’s employment is terminated or constructively terminated without cause, he will receive severance pay and medical benefits for a period of 12 months and all of the options granted to him will immediately vest.
 
As used in each of these agreements, (i) a “change of control” includes the sale or other disposition of all or substantially all of our company’s assets; (ii) a “constructive termination” includes any purported termination of the employee which is not effected for “cause” or for which the grounds relied upon are not valid; and (iii) “cause” includes, among other things, termination of employment due to the employee’s willful, repeated failure substantially to perform his or her duties, a willful act by the employee that constitutes gross misconduct and that is injurious to our company and conviction of a felony crime. It is our position that the asset sale to Bio-Rad does not constitute a change in control, as defined in these agreements. Should the asset sale be deemed to be a change of control, and the aforementioned employees are terminated within twelve months of the proposed asset sale for reasons other than for cause, we would be required to provide the severance pay and benefits described above.

In the asset purchase agreement, we have agreed to provide Bio-Rad and its officers, employees, auditors and other representatives with access to data and information about the transferred assets and the research tools business. We also agreed that between the signing of the asset purchase agreement and closing of the asset sale, subject to certain exceptions, unless Bio-Rad otherwise consents in writing, we will, among other things, carry on the research tools business only in the ordinary course of business and consistent with past practice. We also agreed that, subject to certain exceptions, except in the ordinary course of business, we will not take certain actions related to the research tools business without the prior written consent of Bio-Rad (which consent may not be unreasonably withheld), including changing or amending our certificate of incorporation or bylaws, entering into, extending, materially modifying, terminating or renewing any contract or lease, selling, assigning, selling, otherwise disposing of or encumbering any of the transferred assets, for any employees hired by Bio-Rad, taking any action with respect to granting any bonus, severance or termination pay or with respect to any increase of benefits payable under its severance or termination pay policies or agreements in effect on the date of the asset purchase agreement or increase in any manner the compensation or benefits of any employee or pay any benefit not required by any existing employee plan or policy, entering into or amending any employee plan, agreement, trust, fund or other arrangement for the benefit or welfare of any employee, failing to maintain all employee plans in accordance with applicable regulations, declaring, setting aside, making or paying any dividend or other distribution with respect to our capital stock, failing to expend funds for budgeted capital expenditures or commitments of the research tools business, willingly allowing or permitting to be done any act by which any of the insurance policies may be suspended, impaired or canceled, failing to pay our accounts payable and any debts owed or obligations due to us or to pay or discharge any liabilities related to the research tools business in the ordinary course of business, failing to maintain the assets in substantially their current state of repair, except for normal wear and tear, or failing to replace inoperable, worn out or obsolete or destroyed assets consistent with our past practices, failing to comply in any material respect with all regulations applicable to the assets or the research tools business, intentionally doing any other act which could cause any of our representations or warranties in the asset purchase agreement to be or

become untrue in any material respect, failing to use reasonable commercial efforts to retain our employees involved in the research tools business, to maintain the research tools business so that such employees will remain available to us on and after the close of the asset sale, to maintain existing relationships with suppliers, customers and others having business dealings with us related to the research tools business and otherwise preserve the goodwill of the research tools business, entering into any agreement, or otherwise becoming obligated, to do any action prohibited thereunder, entering into, renewing, modifying or revising any agreement or transaction with any relevant or making any payment of any kind whatsoever to or on behalf of any of the subsidiaries listed as part of the asset purchase agreement, or any officer or director of any of such subsidiaries, pursuant to any agreement between us and any of such subsidiaries or otherwise.
 
Limitations on Considering other Acquisition Proposals
 
We have agreed that we and our officers, directors and other representatives and our subsidiaries will not:
 
  •  directly or indirectly enter into, solicit or continue any discussions or negotiations with, or encourage or respond to any inquiries or proposals by, or participate in any negotiations with, or provide any information to, or otherwise cooperate in any other way with, any entity or person other than Bio-Rad concerning any proposed acquisition transaction;
 
  •  engage in any discussions, negotiations or other communications relating to an acquisition proposal; or
 
  •  furnish to any other person any information with respect to us or our subsidiaries for the purposes of, or otherwise cooperate in any way with, or assist or participate in any effort or attempt by any other person to seek or effect a proposed acquisition transaction.
 
However, prior to the close of the asset sale, we may provide access to our properties and books and records in response to a request by a person who has made an unsolicited bona fide written acquisition proposal if and only to the extent that, prior to taking any of those actions:
 
  •  our board of directors has determined in good faith, after consultation with our outside legal counsel and financial advisors, that the failure to take that action would violate its fiduciary duties under applicable law and that the proposed acquisition transaction constitutes or is reasonably likely to result in a superior proposal from the party that made the proposal for a proposed acquisition transaction; and
 
  •  we inform Bio-Rad promptly after we take the action.
 
A “proposed acquisition transaction” is any discussion, negotiation, inquiry or proposal concerning any sale of all or a portion of the assets or the research tools business or all or substantially all of our capital stock, or any merger, consolidation, liquidation, dissolution or similar transaction involving us.
 
A “superior proposal” is a proposed acquisition transaction:
 
  •  that is reasonably capable of being consummated, taking into account all legal, financial, regulatory, timing, and similar aspects of, and conditions to, the proposal, the likelihood of obtaining necessary financing and the corporation, partnership, person or other entity or group making the proposal; and
 
  •  which, if consummated, would result in a transaction more favorable to our stockholders from a financial point of view than the asset sale as contemplated by the asset purchase agreement.
 
We have agreed that promptly after we receive any written proposal for a proposed acquisition transaction, or any inquiry or contact with any person with respect thereto, we will provide Bio-Rad with oral and written notice of the proposed acquisition transaction and a copy of such offer, and will keep Bio-Rad informed of the status of any negotiations regarding such offer. We have also agreed to notify Bio-Rad immediately if any discussions or negotiations are sought to be initiated, any inquiry or proposal is made, or any information is requested with respect to any proposed acquisition transaction and notify Bio-Rad of the terms of any proposal we may receive in respect of any such proposed acquisition transaction.
 
However, we may terminate the asset purchase agreement if, prior to the close of the asset sale and after compliance in all material respects with the obligations set forth above, we elect to enter into a binding agreement


21

with respect to a superior proposal. In the event of such termination, we have agreed to pay Bio-Rad a termination fee of $2 million.
 
Non-Competition
 
We have agreed, for a period of 5 years after the closing date, that neither we nor any of our subsidiaries, unless acting in accordance with Bio-Rad’s prior written consent, will, directly or indirectly, own, manage, join, operate or control, or participate in the ownership, management, operation or control of, or be connected as a partner, consultant or otherwise with, or permit their names to be used by or in connection with, any profit or non-profit business or organization which produces, designs, conducts research on, provides, sells, distributes or markets products, goods, equipment or services which directly compete with the research tools business as conducted by us immediately prior to the close of the asset sale anywhere in the world other than in the clinical diagnostics market (as that term is defined in the cross license agreement attached as an exhibit to the asset purchase agreement). This limitation does not restrict us from acquiring control of any company or business which derives less than 2% of its revenue from a business that competes directly with the research tools business as conducted by us immediately prior to the closing or making passive investments of less than 2% of the outstanding equity securities in any entity listed on a national stock exchange or quoted on any recognized automatic quotation system.
 
We and Bio-Rad have also agreed that, for a period of 1 year after the closing date, neither we nor Bio-Rad will, directly or indirectly, hire or offer employment to or seek to hire or offer employment to any employee of the other party whose employment is continued by such party after the closing date, unless such other party first terminates the employment of such employee or gives its written consent to such employment or offer of employment.

We and Bio-Rad may terminate the asset purchase agreement:
 
  •  by mutual written consent;
 
  •  by either party if the asset sale has not closed on or before November 1, 2006; or
 
  •  by either party if our stockholders vote not to approve the asset sale and the other transactions contemplated by the asset purchase agreement at the special meeting, or any adjournment or postponement of the special meeting.

Termination Fee
 
The asset purchase agreement requires that we pay Bio-Rad a termination fee of $2 million if, among other things:

Ancillary Agreements
 
Under the asset purchase agreement, we and Bio-Rad have agreed to execute the several ancillary agreements, incorporated as exhibits to the asset purchase agreement, upon the closing of the asset purchase.
 
Indemnification Escrow Agreement
 
Bio-Rad will pay out of the purchase price $2 million to be held in an escrow account in accordance with the terms of an indemnification escrow agreement. The asset purchase agreement provides that we will indemnify Bio-Rad against damages, costs, and losses resulting from any breach of or liabilities resulting from a breach of our representations and warranties, or any covenants or agreements assigned under the asset purchase agreement, from any excluded liabilities and for certain other matters. All of the escrow funds will be available for Bio-Rad to satisfy indemnification claims against us. The escrow funds will held in the escrow account and available for indemnification claims by Bio-Rad for a period of three years, or longer if there are unresolved indemnifiable claims against Ciphergen by Bio-Rad, and will be disbursed to us in accordance with the terms and conditions of the agreement. The escrow fees are to be paid one half by Bio-Rad and one-half by Ciphergen.
 
Cross License Agreement
 
Pursuant to the asset purchase agreement, Bio-Rad acquired certain proprietary rights used in the research tools business. At the closing of the asset purchase, we will enter into a cross license agreement with Bio-Rad where we will retain the right to commercially exploit those proprietary rights, including SELDI technology, in the clinical diagnostics market. The clinical diagnostics market includes laboratories engaged in the research and development or manufacture of assays, or tests, using biomarkers to identify, characterize, define or diagnose a disease state, commercial clinical laboratories, and the development and sale of diagnostic tests. Ciphergen has been granted exclusive rights to commercialize the proprietary rights in the clinical diagnostics market during a five-year exclusivity period. After the end of the five-year period, we and Bio-Rad will share exclusive rights. Ciphergen and Bio-Rad each have the right to engage in negotiations with the other party for a license to any improvements in the proprietary rights created by the other party.
 
Manufacture and Supply Agreement
 
At the closing, we will enter into a manufacture and supply agreement, whereby Bio-Rad will be the sole supplier to Ciphergen of certain instruments and ProteinChip arrays, pursuant to Ciphergen’s specifications. For the first three years of the agreement, Ciphergen agrees to a minimum purchase of specified quantities. If Bio-Rad develops new products using SELDI technology, Bio-Rad has agreed to make such products available to Ciphergen. Ciphergen can also request that Bio-Rad develop and manufacture new products to written specifications and the parties will negotiate in good faith the terms for purchasing such products. If Bio-Rad fails to manufacture or sell the products to Ciphergen, then under certain conditions Ciphergen has the right to manufacture the products or have the products manufactured by a third party. The parties agree to establish a technology escrow to deposit the manufacturing information for the production of the products contemplated by the agreement.
 
Transition Services Agreement
 
Pursuant to a transition services agreement, Ciphergen will provide consulting and IT services at cost, to assist Bio-Rad to become self sufficient with respect to the operation of the research tools business. Bio-Rad will also provide certain consulting services to Ciphergen and also grants Ciphergen access on a continuing basis to certain equipment that will be shared by the parties.
 
Sublease Agreement
 
Pursuant to a sublease agreement, Bio-Rad will sublease a portion of the premises currently occupied by Ciphergen until July 31, 2008. Bio-Rad will pay market rates for the subleased premises.

Stock Purchase Agreement
 
As part of the asset purchase agreement, Bio-Rad agreed to purchase $3 million of Ciphergen common stock pursuant to a stock purchase agreement. The price per share will be $0.972, which is the average closing price of Ciphergen’s common stock on the five trading days immediately preceding August 14, 2006, resulting in a purchase of 3,086,420 shares. The stock purchase agreement provides certain registration rights whereby, if Ciphergen files a registration statement under the Securities Act of 1933, as amended, Bio-Rad may elect to include its shares in that registration, subject to various conditions, as well as certain representations and warranties by Ciphergen to Bio-Rad, including, but not limited to, representations regarding due organization of Ciphergen, the absence of litigation, the absence of conflicts, the acquisition of a fairness opinion, and the accuracy of financial statements. The purchase and sale of the shares pursuant to the stock purchase agreement will be consummated at the closing of the transactions contemplated by the asset purchase agreement with Bio-Rad. If the proposed sale of equity to Bio-Rad is completed, Ciphergen currently intends to utilize the net proceeds to fund the development of our emerging specialty diagnostics business and for other working capital purposes.
 
Opinion of our Financial Advisor
 
Pursuant to an engagement letter dated August 3, 2006, Ciphergen retained Oppenheimer & Co. Inc. to render an opinion to the board of directors of Ciphergen as to the fairness, from a financial point of view, to Ciphergen of the consideration to be received in the asset sale to Bio-Rad.
 
On August 14, 2006, Oppenheimer delivered its oral opinion to the Ciphergen board, subsequently confirmed in writing as of August 14, 2006, to the effect that and subject to the various assumptions set forth therein, as of August 14, 2006, the consideration to be received in the asset sale was fair, from a financial point of view, to Ciphergen. The full text of the written opinion of Oppenheimer, dated August 14, 2006, is attached as Annex C to this proxy statement and is incorporated by reference into this proxy statement. Holders of our common stock are urged to read the opinion in its entirety for the assumptions made, procedures followed, other matters considered and limits of the review by Oppenheimer. The summary of the written opinion of Oppenheimer set forth herein is qualified in its entirety by reference to the full text of such opinion. Oppenheimer’s analyses and opinion were prepared for and addressed to our board and are directed only to the fairness, from a financial point of view, of the consideration to be received in the asset sale to Bio-Rad, and do not constitute an opinion as to the merits of the asset sale to Bio-Rad or a recommendation to any stockholder as to how to vote on the proposed asset sale to Bio-Rad. The consideration received in the asset sale to Bio-Rad was determined through negotiations between us and Bio-Rad and not pursuant to recommendations of Oppenheimer.
 
In arriving at its opinion, Oppenheimer reviewed and considered such financial and other matters as it deemed relevant, including, among other things:
 
  •  a final draft of the asset purchase agreement dated August 14, 2006;
 
  •  certain financial and other information on the assets of our research tools business and certain other relevant financial and operating data furnished to Oppenheimer by our management;
 
  •  certain internal financial analyses, financial projections, reports and other information concerning our research tools business, prepared by our management;
 
  •  certain internal financial analyses, financial projections, reports and other information concerning our remaining diagnostics business, as prepared by our management;
 
  •  discussions Oppenheimer had with certain members of our management including, but not limited to, the historical and current business operations, financial conditions and prospects of our research tools business and such other matters Oppenheimer deemed relevant;
 
  •  certain financial data, stock market performance data and trading multiples of our research tools business as compared to operating results and multiples of certain publicly traded companies Oppenheimer deemed generally comparable;

Table of Contents

 
  •  certain publicly available information regarding recent purchase price multiples of precedent transactions, if any, that Oppenheimer deemed relevant;
 
  •  based on the projections prepared by our management, the cash flows generated by our research tools business on a stand-alone basis to determine the present value of the discounted cash flows; and
 
  •  such other information, financial studies, analyses and investigations and such other factors that Oppenheimer deemed relevant for the purposes of its opinion.
 
In conducting its review and arriving at its opinion, Oppenheimer, (i) with our consent, assumed and relied upon, without independent investigation, the accuracy and completeness of all financial and other information-provided to it by us, or (ii) assumed and relied upon, without independent investigation, the accuracy and completeness of all financial and other information which was publicly available. Oppenheimer did not undertake any responsibility for the accuracy, completeness or reasonableness of, or independently verify, such information. In addition, Oppenheimer did not conduct nor assume any obligation to conduct any physical inspection of the properties or facilities of our research tools business. Oppenheimer further relied upon the assurance of our management that they were unaware of any facts that would make the information provided to Oppenheimer incomplete or misleading in any material respect. Oppenheimer, with our consent, without independent investigation, assumed that the financial projections that it examined were reasonably prepared by our management based on the best available estimates and good faith judgment of management as to the future performance of our tools and diagnostics businesses, and that such projections provided a reasonable basis for its opinion.
 
Oppenheimer did not make or obtain any independent evaluations, valuations or appraisals of the assets or liabilities of our research tools business, nor was Oppenheimer furnished with such materials. With respect to all legal matters relating to Ciphergen, Oppenheimer relied on the advice of our legal counsel. Oppenheimer was not requested to opine as to, and its opinion does not in any manner address, our use of the proceeds from the asset sale to Bio-Rad or our financial viability following the asset sale to Bio-Rad. In addition, Oppenheimer assumed in all respects material to its analysis that we would not be subject to any claims pursuant to the indemnification provisions of the asset purchase agreement. Oppenheimer’s opinion was necessarily based upon economic and market conditions and other circumstances as they existed and could be evaluated by Oppenheimer on the date of its opinion. It should be understood that although subsequent developments may affect Oppenheimer’s opinion, Oppenheimer does not have any obligation to update, revise or reaffirm its opinion and Oppenheimer expressly disclaims any responsibility to do so.
 
In rendering its opinion, Oppenheimer assumed, in all respects material to its analysis, that the representations and warranties of each party contained in the asset purchase agreement are true and correct, that each party will perform all of the covenants and agreements required to be performed by it under the asset purchase agreement and that all conditions to the consummation of the asset sale to Bio-Rad will be satisfied without waiver thereof. Oppenheimer assumed, in all respects material to its analysis, that all governmental, regulatory and other consents and approvals contemplated by the asset purchase agreement would be obtained and that, in the course of obtaining any of those consents, no restrictions will be imposed or waivers made that would have an adverse effect on the contemplated benefits of the asset sale to Bio-Rad.
 
Oppenheimer’s opinion does not constitute a recommendation to any stockholder as to how the stockholder should vote on the proposed asset sale to Bio-Rad or take any other action with respect to the asset sale to Bio-Rad or otherwise. Oppenheimer was not requested to opine as to, and its opinion does not in any manner address, Ciphergen’s underlying business decision to affect the asset sale to Bio-Rad. Oppenheimer did not express any view as to the price or trading range for Ciphergen common stock following consummation of the asset sale to Bio-Rad or otherwise, which may vary depending on numerous factors that generally influence the price of securities. Oppenheimer’s opinion is limited to the fairness, from a financial point of view, of the consideration to be received pursuant to the asset purchase agreement.
 
The following is a summary of the principal financial analyses performed by Oppenheimer to arrive at its opinion. Some of the summaries of financial analyses include information presented in tabular format. In order to fully understand the financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data set forth in the tables


27


Table of Contents

without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the financial analyses. Oppenheimer performed certain procedures, including each of the financial analyses described below, and reviewed with our management the assumptions on which such analyses were based and other factors, including our historical and projected financial results. No limitations were imposed by our board of directors with respect to the investigations made or procedures followed by Oppenheimer in rendering its opinion.
 
Discounted Cash Flow Analysis.  Oppenheimer estimated a range of values for our research tools business based upon the discounted present value of the projected stand-alone, unlevered, after-tax cash flows of our research tools business described in the financial projections provided by our management for the 4th quarter of 2006 through the three fiscal years ending December 31, 2009, and the discounted present value of the terminal value of our research tools business based upon a terminal revenue multiple. Stand-alone, unlevered, after-tax cash flow was calculated by taking projected operating income and subtracting from this amount projected cash taxes and capital expenditures, adding back projected depreciation and amortization and adding or subtracting, as the case may be, changes in working capital. This analysis was based upon projections supplied by our management along with certain other assumptions. In performing this analysis, Oppenheimer utilized discount rates ranging from 15% to 35%, representing 10% +/- Ciphergen’s research tools business calculated weighted average cost of capital. Oppenheimer utilized terminal revenue multiples applied to estimated 2009 revenue ranging from .53x to .76x, which represents the median of its peer group less a discount. Utilizing this methodology, the implied enterprise value reference range of our research tools business is $2.2 million to $3.5 million, based on the financial forecasts.
 
Comparable Company Analysis.  Oppenheimer compared selected historical and projected, to the extent available, operating and financial data for our research tools business to the corresponding financial data and ratios of certain other companies whose securities are publicly traded and which Oppenheimer believes are comparable based on operating, market valuation or other criteria which are similar to our research tools business. In evaluating the peer group, Oppenheimer made judgments and assumptions with regard to disaggregating selected financial information from the genetic, proteomic, and molecular diagnostics industry performance; general business; economic; market; and financial conditions and many other matters, including the impact of competition.
 
Oppenheimer compared certain trading multiple and valuation statistics of a selected group of publicly traded companies in the genetic, proteomic, and molecular diagnostics sectors. Oppenheimer then separated them into three categories: (i) large growing companies with growing or projected to grow revenues, (ii) small growing companies with growing or projected to grow revenues, and (iii) small declining companies with declining or projected to decline revenues, which in Oppenheimer’s judgment were generally comparable to the assets of our research tools business for the purposes of this analysis from both a financial and operational perspective.

There were twelve companies that met the full criteria, four within the large growing category, five within the small growing category and three in the small declining category. These companies were:

    ORCH

    TBIO  
 
The data and ratios included the enterprise value (market equity value, less cash, plus debt, minority interests and preferred stock) of the selected companies as multiples of last twelve months (LTM) revenue, gross profit and EBITDA (in each case, as available from SEC filings, FirstCall Consensus, or if not so available, research analyst reports).
 
The following table presents multiples implied by the ratio of enterprise value to LTM revenue and gross profit for the sub-group of small declining companies within the broader scope of minimal or comparable companies. EBITDA multiples were not meaningful as Ciphergen and the comparable companies have negative EBITDA. The information in the table is based on closing stock prices as of August 11, 2006. Consideration to be received in the asset sale to Bio-Rad is adjusted for purposes of this analysis to take into account the likelihood of receipt of payment of certain contingent payments and time value. With respect to figures presented in the column entitled “Multiple Implied by Consideration to be Received in the asset sale to Bio-Rad,” LTM revenue and gross profit are as per our management.

Enterprise Value as a ratio of:
                                       
LTM Revenue
    0.6x       0.8x       0.8x       1.2x       0.8x  
LTM Gross Profit
    1.2x       1.9x       2.2x       2.4x       1.6.x  
 
Oppenheimer noted that the three companies that compose the group of small declining companies with declining or projected to decline revenues utilized in the comparable company analysis were, as of August 14, 2006, sufficiently similar to Ciphergen in terms of industry and financial and operational perspective. No company utilized in the comparable company analysis was identical to the stand-alone assets of Ciphergen’s research tools business. Thus, Oppenheimer concluded that, on a Comparable Company Analysis, based on the current stand-alone assets of our research tools business, that the range of enterprise value to LTM revenue multiples for the small declining companies ranges from 0.6x to 1.2x, with an average of 0.8x, yielding a value of $19.6 million.
 
Precedent Mergers and Acquisition Transactions Analysis.  Oppenheimer compared certain publicly available statistics from SEC filings, company press releases, publicly available research and other sources of selected precedent mergers and acquisitions from January 1, 2004 to August 11, 2006 involving companies that


29


Table of Contents

operate in the genomic, proteomic, and molecular research and diagnostic device industry or in a similar industry, which Oppenheimer deemed comparable to the transaction between our research tools business and Bio-Rad.
 
Oppenheimer noted that the analysis of precedent transactions necessarily involves complex considerations and judgments concerning differences in financial and operating characteristics, form of consideration, acquisition terms, sale terms, and other factors that would necessarily affect the purchase value of our research tools business versus the acquisition value of any other comparable company in general and the transactions Oppenheimer analyzed in particular. Oppenheimer further noted that none of the precedent merger and acquisition transactions were sufficiently similar to the sale of our research tools business to Bio-Rad. Oppenheimer concluded that this valuation method is not appropriate due to the lack of truly comparable transactions and the declining and projected to decline financial and operational nature of our research tools business.
 
Implied Market Valuation Analysis.  Oppenheimer calculated the implied equity value of the stand-alone assets of our research tools business by subtracting the calculated equity value of our stand-alone diagnostics business from our current market equity value. Oppenheimer calculated the contribution of our combined tools and diagnostics businesses, yielding an equity value of $35.5 million, based on our closing stock price on August 11, 2006. Oppenheimer then calculated the sum of the net present value of our future pro forma free cash flows for our stand-alone diagnostics business, plus the estimated present value of the terminal equity value of our stand-alone diagnostics business, which is based on the median price to earnings ratio (PE) of certain diagnostic comparable companies. The analysis showed that the present value of the stand-alone diagnostics business exceeded our equity value of $35.5 million, implying a negative equity value for our research tools business.
 
The summary set forth above does not purport to be a complete description of all the analyses performed by Oppenheimer. The preparation of a fairness opinion involves various determinations as to the most appropriate and relevant methods of financial analyses and the application of these methods to the particular circumstances and, therefore, such an opinion is not readily susceptible to partial analysis or summary description. Oppenheimer did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, notwithstanding the separate factors summarized above, Oppenheimer believes, and has advised our board of directors, that its analyses must be considered as a whole and that selecting portions of its analyses and the factors considered by it, without considering all analyses and factors, could create an incomplete view of the process underlying its opinion. In performing its analyses, Oppenheimer made numerous assumptions with respect to industry performance, business and economic conditions and other matters, many of which are beyond our control. These analyses performed by Oppenheimer are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by such analyses. In addition, analyses relating to the value of businesses do not purport to be appraisals or to reflect the prices at which businesses or securities may actually be sold. Accordingly, such analyses and estimates are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors. None of Ciphergen, Oppenheimer, or any other person assumes responsibility if future results are materially different from those projected.
 
Oppenheimer was selected by our board of directors to render an opinion to it because Oppenheimer is an internationally recognized investment banking firm and because, as part of its investment banking business, Oppenheimer is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. In addition, in the ordinary course of its business, Oppenheimer and its affiliates may trade the equity securities of Ciphergen and Bio-Rad for their own account and for the accounts of their customers, and, accordingly, may at any time hold a long or short position in such securities.
 
Pursuant to the engagement letter, for Oppenheimer’s services in providing the fairness opinion, we have agreed to pay Oppenheimer a cash fee of $250,000, of which $50,000 is payable upon signing of the engagement agreement, $150,000 payable upon delivery of the written opinion to Ciphergen and the remaining balance of $50,000 payable upon closing of the sale to Bio-Rad. Additionally, we have agreed to reimburse Oppenheimer for its reasonable out-of-pocket expenses, including reasonable attorneys’ fees and expenses and have agreed to indemnify Oppenheimer against certain liabilities, including liabilities under the federal securities laws. The terms of the fee arrangement with Oppenheimer, which are customary in transactions of this nature, were negotiated at


30


Table of Contents

arm’s length between us and Oppenheimer, and our board of directors was aware of the arrangement, including the fact that a portion of the fee payable to Oppenheimer is contingent upon the completion of the asset sale to Bio-Rad. In addition, Oppenheimer has been retained by Ciphergen to assist in other investment-banking advisory services, for which Oppenheimer will be paid its standard fees.
 
PROPOSAL NO. 2 — PROPOSAL TO GRANT AUTHORITY TO ADJOURN OR POSTPONE THE
SPECIAL MEETING
 
This section of the proxy statement describes material aspects of the proposed adjournment or postponement of the special meeting. This summary may not contain all of the information that is important to you. You should carefully read this proxy statement for a more complete understanding of the adjournment or postponement of the special meeting.
 
The Ciphergen Adjournment Proposal
 
If, at the special meeting of stockholders on Thursday, October 26, 2006, the number of shares of Ciphergen common stock present or represented and voting in favor of adoption of the asset sale to Bio-Rad is insufficient to adopt that proposal under the Delaware General Corporation Law, proxy holder Gail S. Page intend to move to adjourn the special meeting in order to enable our board of directors to solicit additional proxies in respect of such proposal. In that event, we will ask our stockholders to vote only upon the adjournment proposal, and not the proposal regarding the asset sale to Bio-Rad.
 
In this proposal, we are asking you to authorize the holder of any proxy solicited by our board of directors to vote in favor of granting discretionary authority to Gail S. Page to adjourn or postpone the special meeting to another time and place for the purpose of soliciting additional proxies. If the stockholders approve the adjournment proposal, we could adjourn the special meeting and any adjourned session of the special meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from stockholders that have previously voted. Among other things, approval of the adjournment proposal could mean that, even if we had received proxies representing a sufficient number of votes against the approval of the asset sale to Bio-Rad to defeat that proposal, we could adjourn the special meeting without a vote on the asset sale proposal and seek to convince the holders of those shares to change their votes to votes in favor of approval of the asset sale.
 
Vote Required and Board Recommendation
 
The Ciphergen adjournment proposal requires the approval of a majority of the votes cast on the proposal. Broker non-votes and abstentions will have no effect on the outcome of the vote on the adjournment proposal. No proxy that is specifically marked “against” adoption of the asset sale will be voted in favor of the Ciphergen adjournment proposal, unless it is specifically marked “for” the Ciphergen adjournment proposal.
 
Our board of directors believes that, if the number of shares of Ciphergen common stock present or represented at the special meeting and voting in favor of adoption of the asset sale to Bio-Rad is insufficient to approve that proposal, it is in the best interests of our stockholders to enable our board of directors to continue to seek to obtain a sufficient number of additional votes in favor of adoption of the asset sale proposal to bring about its approval.
 
Our board of directors recommends that you vote “FOR” the Ciphergen adjournment proposal.

(c) Rents.  Seller shall pay all rent under the Leases through the end of the calendar month in which the Closing Date occurs, and Buyer shall reimburse Seller for such rent accrued from the Closing Date through the end of such month as part of the post-Closing proration. Payments of percentage rent, if any, due under the provisions of the Leases shall be adjusted to the Closing Date as follows. Buyer shall pay any percentage rent due for periods expiring after the Closing Date, and Seller shall be responsible for that portion of such percentage rent paid by Buyer and due under the Leases based on sales from the commencement of the current lease year through the Closing Date, and Buyer shall be responsible for that portion due under the Lease based on sales from and after the Closing Date. Within ninety (90) calendar days after the Closing Date, Seller will furnish to Buyer records which evidence the gross sales of Seller at each Facility to the extent necessary to enable Buyer to comply with the percentage rent provision of each Lease.

Following the payment of any such Property Taxes by the Buyer after the Closing Date, the Seller shall, upon request, promptly pay to the Buyer an amount equal to the Seller’s Share of Property Taxes.

ACTIONS BY SELLER AND BUYER
AFTER THE CLOSING

The party requesting any such Books and Records, information or employees shall bear all of the out-of-pocket costs and expenses (including without limitation attorneys’ fees, but excluding reimbursement for salaries and employee benefits) reasonably incurred in connection with providing such Books and Records, information or employees. All information received pursuant to this Section 10.2(a) shall be subject to the terms of the Confidentiality Agreement.

to be shown on any tax return of the other for any period. Without limiting the generality of the foregoing, Buyer and Seller shall each retain, until the applicable statutes of limitations (including any extensions) have expired, copies of all tax returns, supporting work schedules, and other records or information that may be relevant to such returns for all tax periods or portions thereof ending on or before the Closing Date and shall not destroy or otherwise dispose of any such records without first providing the other party with a reasonable opportunity to review and copy the same.
 
10.3  Survival of Representations, Etc.  All of the representations, warranties, covenants and agreements made by each party in this Agreement or in any attachment, Exhibit, the Disclosure Schedule, certificate, document or list delivered by any such party pursuant hereto shall survive the Closing for a period of (and claims based upon or arising out of such representations, warranties, covenants and agreements may be asserted at any time before the date which shall be) [three (3)] years following the Closing (except with respect to the representations and warranties set forth Sections 4.20 and 4.26, which shall survive until the expiration of the applicable statute of limitations (with extensions) with respect to the matters addressed in such sections). Each party hereto shall be entitled to rely upon the representations and warranties of the other party set forth in this Agreement. The termination of the representations and warranties provided herein shall not affect the rights of a party in respect of any Claim made by such party in a writing received by the other party prior to the expiration of the applicable survival period provided herein.
 
10.4  Indemnifications.
 
(a) By Seller.  Seller shall indemnify, save and hold harmless and defend Buyer, its affiliates and subsidiaries, and its and their respective Representatives, from and against any and all costs, losses (including without limitation diminution in value), Taxes, Liabilities, obligations, damages, lawsuits, deficiencies, claims, demands, and expenses (whether or not arising out of third-party claims), including without limitation interest, penalties, costs of mitigation, losses in connection with any Environmental Law (including without limitation any clean-up or remedial action), lost profits and other losses resulting from any shutdown or curtailment of operations, damages to the environment, attorneys’ fees and all amounts paid in investigation, defense or settlement of any of the foregoing (herein, “Damages”), incurred in connection with, arising out of, resulting from or incident to (i) any breach of any representation or warranty or the inaccuracy of any representation, made by Seller in or pursuant to this Agreement; (ii) any breach of any covenant or agreement made by Seller in or pursuant to this Agreement; (iii) any Excluded Liability (iv) any Liability imposed upon Buyer by reason of Buyer’s status as transferee of the Business or the Assets directly resulting from any breach of any representation, warranty, covenant or agreement made by Seller in or pursuant to this Agreement; or (v) any Liability imposed upon Buyer related to the United States Patent Nos. 5,504,326, 5,510,613, 5,712,479, 5,625,184, 5,627,369, 5,760,393, 6,002,127, 6,057,543, 5,641,959, and 5,654,545, including any division, continuation, continuation-in-part, reexamination, reissue, or foreign equivalent or counterpart thereof, or any other patent asserted by Bruker Daltonics, Inc., Indiana University, or Applera Corp. relating to Space-Velocity Correlation Focusing or Delayed Extraction, or (vi) any Liability imposed upon Buyer related to any Patent in which a claim of infringement is made against the making, using, selling, or importation of the laser incorporated within the ProteinChip System, Series 4000 instrument as of the Closing Date.
 
The term “Damages” as used in this Section 10.4 is not limited to matters asserted by third parties against Seller or Buyer, but includes Damages incurred or sustained by Seller or Buyer in the absence of third party claims. Payments by Buyer of amounts for which Buyer is indemnified hereunder, and payments by Seller of amounts for which Seller is indemnified, shall not be a condition precedent to recovery. Seller’s obligation to indemnify Buyer, and Buyer’s obligation to indemnify Seller, shall not limit any other rights, including without limitation rights of contribution which either party may have under statute or common law.
 
(b) By Buyer.  Buyer shall indemnify and save and hold harmless and defend Seller, its respective affiliates and subsidiaries, and its respective Representatives from and against any and all Damages incurred in connection with, arising out of, resulting from or incident to (i) any breach of any representation or warranty or the inaccuracy of any representation, made by Buyer in or pursuant to this Agreement; (ii) any breach of any covenant or agreement made by Buyer in or pursuant to this Agreement; or (iii) from and after the Closing, any Assumed Liability or the operations of the Business by Buyer.
 
(c) Cooperation.  The indemnified party shall cooperate in all reasonable respects with the indemnifying party and such attorneys in the investigation, trial and defense of such lawsuit or action and any appeal arising


A-34


Table of Contents

therefrom; provided, however, that the indemnified party may, at its own cost, participate in the investigation, trial and defense of such lawsuit or action and any appeal arising therefrom. The parties shall cooperate with each other in any notifications to insurers.
 
(d) Defense of Claims.  If a claim for Damages (a “Claim”) is to be made by an indemnified party hereunder against the indemnifying party, the indemnified party shall give written notice (a “Claim Notice”) to the indemnifying party as soon as practicable after the indemnified party becomes aware of any fact, condition or event which may give rise to Damages for which indemnification may be sought under this Section 10.4. If any lawsuit or enforcement action is filed against any party entitled to the benefit of indemnity hereunder, written notice thereof shall be given to the indemnifying party as promptly as practicable (and in any event within fifteen (15) calendar days after the service of the citation or summons). The failure of any indemnified party to give timely notice hereunder shall not affect rights to indemnification hereunder, except to the extent that the indemnifying party demonstrates actual damage caused by such failure. The indemnifying party shall be entitled, if it so elects at its own cost, risk and expense, (i) to take control of the defense and investigation of such lawsuit or action, (ii) to employ and engage attorneys of its own choice to handle and defend the same unless the named parties to such action or proceeding include both the indemnifying party and the indemnified party and the indemnified party has been advised in writing by counsel that there may be one or more legal defenses available to such indemnified party that are different from or additional to those available to the indemnifying party, in which event the indemnified party shall be entitled, at the indemnifying party’s cost, risk and expense, to separate counsel of its own choosing, and (iii) to compromise or settle such claim, which compromise or settlement shall be made only with the written consent of the indemnified party, such consent not to be unreasonably withheld, unless the indemnifying party shall agree to pay the full amount of such settlement. If the indemnifying party fails to assume the defense of such claim within fifteen (15) calendar days after receipt of the Claim Notice, the indemnified party against which such claim has been asserted will (upon delivering notice to such effect to the indemnifying party) have the right to undertake, at the indemnifying party’s cost and expense, the defense, compromise or settlement of such claim on behalf of and for the account and risk of the indemnifying party, provided that any such settlement of claim shall be made only with the written consent of the indemnifying party unless the indemnified party shall agree to pay the full amount of such settlement. In the event the indemnified party assumes the defense of the claim, the indemnified party will keep the indemnifying party reasonably informed of the progress of any such defense, compromise or settlement.
 
(e) Product and Warranty Liability.  The provisions of this Section 10.4 shall cover, without limitation, all Liabilities of whatsoever kind, nature or description relating, directly or indirectly, to product liability, litigation or claims against Buyer or Seller in connection with, arising out of, or relating to products sold or shipped from the Facilities by Buyer or Seller, respectively.
 
(f) Brokers and Finders.  Pursuant to the provisions of this Section 10.4, each of Buyer and Seller shall indemnify, hold harmless and defend the other party from the payment of any and all broker’s and finder’s expenses, commissions, fees or other forms of compensation which may be due or payable from or by the indemnifying party, or may have been earned by any third party acting on behalf of the indemnifying party in connection with the negotiation and execution hereof and the consummation of the transactions contemplated hereby.
 
(g) Representatives.  No individual Representative of any party shall be personally liable for any Damages under the provisions contained in this Section 10.4. Nothing herein shall relieve either party of any Liability to make any payment expressly required to be made by such party pursuant to this Agreement.
 
(h) Limitation on Indemnity.  Notwithstanding the foregoing, the maximum aggregate amount of Damages Seller shall be liable pursuant to this Section 10.4 shall be Twenty Million Dollars ($20,000,000) in the aggregate; provided, however, that the maximum aggregate amount of Damages Seller shall be liable pursuant to this Section 10.4 with respect to the Seldi Patent shall be Ten Million Dollars ($10,000,000).
 
10.5  Bulk Sales.  It may not be practicable to comply or attempt to comply with the procedures of the “Bulk Sales Act” or similar law of any or all of the states in which the Assets are situated or of any other state which may be asserted to be applicable to the transactions contemplated hereby. Accordingly, to induce Buyer to waive any requirements for compliance with any or all of such laws, Seller hereby agrees that the indemnity provisions of Section 10.4 hereof shall apply to any Damages of Buyer arising out of or resulting from the failure of Seller or Buyer to comply with any such laws.

10.6  Covenant Not to Compete.
 
(a) Recitals.  Seller acknowledges and agree that Seller has technical expertise associated with the Business and is well known in the life sciences industry. In addition, Seller has valuable business contacts with clients and potential clients of the Business and with professionals in the life sciences industry. Seller’s reputation and goodwill are an integral part of its business success throughout the areas where it conducts the Business. If Seller deprives Buyer of any of Seller’s goodwill or in any manner uses its reputation and goodwill in competition with the Business, Buyer will be deprived of the benefits it has bargained for pursuant to this Agreement. Since Seller has the ability to compete with Buyer in the operation of the Business, Buyer therefore desires that Seller enter into this Covenant Not To Compete. But for Seller’s entry into this Covenant Not to Compete, Buyer would not have entered into the Purchase Agreement with Seller.
 
(b) Covenant Not to Compete.  Seller agrees that for a period of five (5) years after the Closing Date (the “Term”), neither Seller nor any of its respective Subsidiaries, unless acting in accordance with Buyer’s prior written consent, shall, directly or indirectly, own, manage, join, operate or control, or participate in the ownership, management, operation or control of, or be connected as a partner, consultant or otherwise with, or permit their names to be used by or in connection with, any profit or non-profit business or organization which produces, designs, conducts research on, provides, sells, distributes or markets products, goods, equipment or services which, directly competes with the Business, as conducted by Seller immediately prior to the Closing, anywhere in the world other than in the Clinical Diagnostics Market (as that term is defined in the Cross-License Agreement); it being understood that the foregoing shall not limit Seller from (a) acquiring control of any company or business which derives less than 2% of its revenues from a business which competes directly with the Business as conducted by Seller immediately prior to the Closing or (b) making passive investments of less than 2% of the outstanding equity securities in any entity listed for trading on a national stock exchange or quoted on any recognized automatic quotation system.
 
(c) Severability of Provisions.  If any covenant set forth in this agreement is determined by any court to be unenforceable by reason of its extending for too great a period of time or over too great a geographic area, or by reason of its being extensive in any other respect, such covenant shall be interpreted to extend only for the longest period of time and over the greatest geographic area, and to otherwise have the broadest application as shall be enforceable. The invalidity or unenforceability of any particular provision of this agreement shall not affect the other provisions hereof, which shall continue in full force and effect. Without limiting the foregoing, the covenants contained herein shall be construed as separate covenants, covering their respective subject matters, with respect to each of the separate cities, counties and states of the United States, and each other country, and political subdivision thereof, in which any of Seller or its successors now transacts any business.
 
(d) Injunctive Relief.  Seller acknowledges that (i) the provisions of Section 10.6(b) and (c) are reasonable and necessary to protect the legitimate interests of Buyer, and (ii) any violation of paragraphs (b) or (c) of this Section 10.6 will result in irreparable injury to Buyer, the exact amount of which will be difficult to ascertain, and that the remedies at law for any such violation would not be reasonable or adequate compensation to Buyer for such a violation. Accordingly, Seller agrees that if Seller violates the provisions of Section 10.6(b) or (c), in addition to any other remedy which may be available at law or in equity, Buyer shall be entitled to specific performance and injunctive relief, without posting bond or other security, and without the necessity of proving actual damages.
 
10.7  Taxes.  Subject to Section 2.6, Seller shall pay, or cause to be paid, when due all Taxes for which Seller is or may be liable or that are or may become payable with respect to all taxable periods ending on or prior to the Closing Date.

(iv) Seller agrees, in consideration of Buyer entering into this Agreement, that in the event that (A) (i) Buyer terminates this Agreement in accordance with Section 11.1(a)(ii) as a result of the conditions to Buyer’s obligations to close specified in Article VIII not having been satisfied (provided that at such time all of the conditions to Seller’s obligation to close specified in Article VII have been satisfied by Buyer or validly waived), or (ii) Seller terminates this Agreement (a) for any reason prior to November 1, 2006, or (b) for any reason after November 1, 2006 (provided that, except in the case of termination by Seller for the reason set forth in Section 11.1(a)(iv), at such time all of the conditions to Seller’s obligation to close specified in Article VII have been satisfied by Buyer or validly waived), or (B) Buyer or Seller terminates this Agreement in accordance with Section 11.1(a)(iii) and within 9 months thereafter Seller closes a transaction in which it sells or otherwise transfers all or substantially all of the assets comprising the Business to a third party, then (if any of the events set forth in (A) or (B) occur) Seller shall, within two (2) days after such termination or closing, as applicable, pay Buyer an amount equal to Two Million Dollars ($2,000,000).

ANNEX B: NEW BUSINESS STRATEGY
 
Overview
 
Ciphergen is dedicated to the discovery, development and commercialization of specialty diagnostic tests that help physicians manage their patients and that improve patient outcomes. We intend to do this using translational proteomics, which is the process of answering clinical questions by utilizing advanced protein separation tools to identify combinations of biomarkers (or, better, to resolve variants of specific biomarkers), developing assays, and commercializing tests.
 
Through collaborations with leading academic and research institutions, including The Johns Hopkins School of Medicine, The University of Texas M. D. Anderson Cancer Center, University College London, and The University of Texas Medical Branch, Ciphergen plans to develop diagnostic tests in the fields of cancer, cardiovascular disease, and women’s health. The clinical questions we are addressing include early disease detection, treatment response, monitoring of disease progression, prognosis and others. In July 2005, we entered into a strategic alliance agreement with Quest Diagnostics Incorporated covering a three year period during which the parties have agreed to develop and commercialize up to three diagnostic tests based on SELDI technology.
 
Our most advanced program is in the field of ovarian cancer. Commonly known as the “silent killer,” ovarian cancer leads to approximately 14,000 deaths each year in the United States. Approximately 23,000 new cases are diagnosed each year, with the majority in patients with late stage disease, where the cancer has spread beyond the ovary. Unfortunately, the prognosis is poor in these patients, leading to the high mortality from this disease. One unmet clinical need is a diagnostic test that can provide adequate predictive value to stratify patients with a pelvic mass into high risk of invasive ovarian cancer versus those with a low risk. We believe that there are at least 5 million testing opportunities each year addressing this need. Ciphergen has developed a panel of biomarkers that we believe provides risk stratification information for ovarian cancer based on a series of studies involving over 2,000 clinical samples from more than five sites. We recently reported the results of a prospective clinical trial involving over 200 consecutive women to test specifically the performance of this marker panel in a realistic patient population, and achieved 80% positive predictive value (the likelihood that a positive test result is truly invasive epithelial ovarian cancer) which is better than other available diagnostic modalities in this patient cohort, such as CA125. Ciphergen is currently working with Quest Diagnostics in their efforts to commercialize this marker set under the analyte specific reagent, or ASR, regulations. In addition, Ciphergen is simultaneously undertaking a prospective clinical trial to support submission to the FDA for approval as an in vitro diagnostic test.
 
The Diagnostics Market Opportunity
 
The economics of health care demand improved allocation of resources. Improved allocation of resources can be derived through disease prevention, early detection of disease leading to early intervention, and from diagnostic tools that can triage patients to more appropriate therapy and intervention. According to the Lewin Group, the worldwide market for diagnostics in 2005 was approximately $29 billion.
 
We have chosen to focus primarily in the areas of oncology, cardiovascular disease, and women’s health. Demographic trends suggest that, as the population ages, the burden from these diseases will increase, and the demand for quality diagnostic, prognostic, and predictive tests will increase. In addition, these areas generally lack quality diagnostic tests and therefore we believe patient outcomes can be significantly improved by the development of novel diagnostic and risk stratification tests.
 
Cancer represents the second leading cause of death in the United States. Over 500,000 Americans die of cancer each year. While many cancer types are preventable, others are not. Even among patients with clear risk factors (for example, HPV infection for cervical cancer), health care providers still generally lack the ability to distinguish those who will get cancer from those who will not. Consequently, there is a clear unmet need to stratify these individuals. Breast cancer is the second most common non-skin cancer among women, with approximately 270,000 new cases of invasive and in situ cancer diagnosed in 2005. Breast cancer kills more women than any other cancer except for lung cancer, with approximately 40,000 deaths from breast cancer in 2005. While much less common than breast cancer, ovarian cancer is the most lethal gynecological malignancy, with approximately 15,300


B-1


Table of Contents

deaths due to ovarian cancer in 2005. Prostate cancer is the most common non-skin cancer among men, with approximately 230,000 cases in 2005.
 
Cardiovascular disease is the leading cause of morbidity and mortality in industrial countries. Over 64 million Americans are affected by at least one type of cardiovascular disease, and close to 1 million die from cardiovascular disease each year — more than from all the cancers combined. The prevalence of cardiovascular disease is expected to increase, not just because of the aging population, but also because of the rapid increase in obesity. More health care dollars are spent on cardiovascular disease than on any other disease, and the estimated annual cost of cardiovascular disease (both indirect and direct) is $368 billion, twice that of cancer. Cardiovascular disease represents a prime opportunity for new diagnostic tests, particularly those that can monitor cardiovascular health or that can predict poor prognosis. Prevention and surveillance are accepted paradigms in cardiovascular medicine; therefore, market acceptance of these types of tests is likely to be high. There is no non-invasive test currently available to distinguish between coronary artery disease and peripheral arterial disease. Such a test would allow physicians to prescribe the appropriate type of treatment.
 
In the field of women’s health, outside of gynecologic malignancies, the field of reproductive health contains many potential opportunities. For example, as women wait longer to have children, the reliance on assisted reproductive technologies, or ART, increases and the potential for obstetric complications increases. Tests aimed at assessing the viability of oocytes during the process of ART may help patients and physicians improve the efficiency of the process, as well as decrease the likelihood of multiple births. In 2003, approximately 90,000 cycles of ART were initiated, resulting in approximately 25,000 live-birth deliveries. More than a third of pregnancies contained multiple fetuses.
 
Our focus on proteomics enables us to address the market for diagnostic tests that measure multiple protein biomarkers, simultaneously. A protein biomarker is a protein or protein variant that is present in a greater or lesser amount in a disease state versus a normal condition. Conventional proteomic tests measure a single protein biomarker whereas most diseases are complex. We believe that efforts to diagnose cancer and other complex diseases have failed in large part because the disease is heterogeneous at the causative level (i.e., most diseases can be traced to multiple potential etiologies) and at the human response level (i.e. each individual afflicted with a given disease can respond to that ailment in a specific manner). Consequently, measuring a single protein biomarker when multiple protein biomarkers may be altered in a complex disease is unlikely to provide meaningful information about the disease state. Our approach, using mass spectrometry, allows us to create diagnostic tests with sufficient sensitivity and specificity to aid the physician considering treatment options for patients with complex diseases.
 
Scientific Background
 
Genes are the hereditary coding system of living organisms. Genes encode proteins that are responsible for cellular functions. The study of genes and their functions has led to the discovery of new targets for drug development. Industry sources estimate that within the human genome there are approximately 30,000 genes. The initial structure of a protein is determined by a single gene. The final structure of a protein is frequently altered by interactions with additional genes or proteins. These subsequent modifications result in hundreds of thousands of different proteins. In addition, proteins may interact with one another to form complex structures that are ultimately responsible for cellular functions.
 
Genomics allows researchers to establish the relationship between gene activity and disease. However, many diseases are manifested not at the genetic level, but at the protein level. The complete structure of modified proteins cannot be determined by reference to the encoding gene alone. Thus, while genomics provides some information about diseases, it does not provide a full understanding of disease processes.
 
The Relationship Between Proteins and Diseases
 
The entire genetic content of any organism, known as its genome, is encoded in strands of deoxyribonucleic acid, or DNA. Cells perform their normal biological functions through the genetic instructions encoded in their DNA, which results in the production of proteins. The process of producing proteins from DNA is known as gene expression or protein expression. Differences in living organisms result from variability in their genomes, which can affect the types of genes expressed and the levels of gene expression. Each cell of an organism expresses only

approximately 10% to 20% of the genome. The type of cell determines which genes are expressed and the amount of a particular protein produced. For example, liver cells produce different proteins from those produced by cells found in the heart, lungs, skin, etc. Proteins play a crucial role in virtually all biological processes, including transportation and storage of energy, immune protection, generation and transmission of nerve impulses and control of growth.
 
Diseases may be caused by a mutation of a gene that alters a protein directly or indirectly, or alters the level of protein expression. These alterations interrupt the normal balance of proteins and create disease symptoms. A protein biomarker is a protein or protein variant that is present in a greater or lesser amount in a disease state versus a normal condition. By studying changes in protein biomarkers, researchers may identify diseases prior to the appearance of physical symptoms. Historically, researchers discovered protein biomarkers as a byproduct of basic biological disease research. This has resulted in the validation by researchers of approximately 200 protein biomarkers that are being used in commercially available clinical diagnostic products.
 
Limitations of Existing Diagnostic Approaches and Ciphergen’s Solution
 
The in vitro diagnostics industry manufactures and distributes products that are used to detect thousands of individual components present in human derived specimens. However, the vast majority of these assays are used specifically to identify single protein biomarkers. The development of new diagnostic products has been limited by the complexity of disease states, which may be caused or characterized by several or many proteins or post-translationally modified protein variants. Diagnostic assays that are limited to the detection of a single protein often have limitations in clinical specificity (true negatives) and sensitivity (true positives) due to the complex nature of many diseases and the inherent biological diversity among populations of people. Diagnostic products that are limited to the detection of a single protein may lack the ability to detect more complex diseases, and thus produce results that are unacceptable for practical use.
 
The heterogeneity of disease and of the human response to disease underlie the shortcoming of single markers to diagnose accurately and to predict many diseases. Our studies, particularly in ovarian cancer, have given us a better understanding of both the disease pathophysiology and the host response. By using multiple markers, we are better able to encompass the disease and host response heterogeneity. In addition, by examining specific analytes with greater resolution, for example, post-translational modifications, we believe we can improve the specificity of our diagnostic markers because these modifications reflect both the pathophysiology and host response. We utilize translational proteomics, i.e., the process of answering clinical questions by utilizing advanced protein separation tools to identify combinations of biomarkers (or better to resolve variants of specific biomarkers), developing assays, and commercializing tests.
 
Ciphergen is applying proteomics research and development tools and methods to analyze biological information in an attempt to discover associations between proteins, protein variants, and protein-protein interaction and diseases. Ciphergen intends to develop new diagnostic tests based on known and newly-identified protein markers to help physicians predict an individual’s predisposition in order better to characterize, monitor progression of, and select appropriate therapy for, diseases. Our goals are to:
 
  •  Develop high-value diagnostic tests that address unmet medical needs, particularly in stratifying patients according to the risk of developing a disease, having a disease, or failing a specific therapy for a disease
 
  •  Facilitate more efficient clinical trials of new therapeutics by providing biomarkers that stratify patients according to likelihood of response
 
  •  Identify biomarkers that can form the basis of molecular imaging targets

Addressing the heterogeneity of disease
 
Ciphergen’s strategy is to create a paradigm of diagnostics that is based on risk stratification, multiple-marker testing, and information integration. This strategy is based on the belief that any specific disease is heterogeneous and therefore relying on a single disease marker to provide a simple “yes-no” answer is likely to fail. We believe that efforts to diagnose cancer and other complex diseases have failed in large part because the disease is heterogeneous at the causative level, meaning that most diseases can be traced to multiple potential etiologies, and at the human response level, meaning that each individual afflicted with a given disease can respond to that ailment in a specific manner. A better understanding of heterogeneity of disease and human response is necessary for improved diagnosis and treatment of many diseases.
 
Validation of markers through proper study design
 
Analysis of peer-reviewed publications reveals almost daily reports of novel biomarkers or biomarker combinations associated with specific diseases. Few of these are used clinically. As with drug discovery, preliminary research results fail to canvass sufficient variation in study populations or laboratory practices and, therefore, the vast majority of candidate biomarkers fail to be substantiated in subsequent studies. Recognizing that validation is the point at which most biomarkers fail, Ciphergen’s strategy is to reduce the attrition rate between discovery and clinical implementation by building validation into the discovery process. Biomarkers fail to validate for a number of reasons, which can be broadly classified into pre-analytical and analytical factors. Pre-analytical factors include study design that does not mimic actual clinical practice, inclusion of the wrong types of control individuals, and demographic bias (usually seen in studies in which samples are collected from a single institution). Analytical factors include poor control over laboratory protocols, inadequate randomization of study samples, and instrumentation biases (for example, higher signal early in the experimental run compared to later in the experimental run). Finally, the manner in which the data are analyzed can have a profound impact on the reliability of the statistical conclusions.
 
When designing clinical studies, Ciphergen begins with the clinical question, since this drives the downstream clinical utility of the biomarkers. With this as a starting point, Ciphergen is able to design a study that includes the appropriate cases and control groups. Ciphergen further incorporates an initial validation component even within the discovery component. Therefore, Ciphergen places an emphasis on multi-institutional studies, inclusion of clinically relevant controls, and partitioning of training from validation data. For example, in the 2004 Cancer Research paper describing the first three markers in the ovarian cancer panel, more than 600 samples taken from five hospitals were analyzed. These samples were divided into individual training sets, followed by a first round of validation samples and then a second round of independent validation samples. Subsequently, Ciphergen has analyzed more than 2,000 samples from five additional medical centers. Ciphergen has examined over 300 samples in its breast cancer program and over 400 samples in its prostate cancer program. In analyzing the complex proteomics data, Ciphergen takes an agnostic view of statistical methodologies, choosing to use a variety of approaches and looking for concordance between approaches, taking the view that markers deemed significant by multiple statistical algorithms are more likely to reflect biological conditions rather than mathematical artifacts.

Exploiting the power of mass spectrometry to improve assay specificity
 
An important characteristic of proteins is that their functional activity is often modulated by changes in their structure. Conventional approaches to assay proteins have variable ability to detect these changes, and may depend on the specificity of the antibody to the original or altered forms of the proteins. Additionally, a conventional assay may inadvertently measure only one form of a protein while many exist. Ciphergen has developed programs for biomarkers in which mass spectrometry provides an advantage over traditional assays in characterizing and quantitating disease markers. Mass spectrometry’s advantages over traditional assay approaches in these instances is a result of its ability to distinguish two or more highly related protein species based on molecular mass, or in combination with chromatographic separation tools, such as with ProteinChip arrays, based on biochemical properties. Because most traditional assay approaches rely strictly on using antibodies to capture the intended analyte, protein forms with a common epitope are not readily distinguished. A few examplar proteins that are candidates for this approach include von Willebrand’s factor, human chorionic gonadotropin, albumin, c-reactive protein, and serum amyloid A. One disease that Ciphergen is specifically addressing is TTP, a disease that affects mostly women and is a result of a deficiency in the enzyme ADAMTS13, which cleaves von Willebrand’s factor. Current assays rely on unwieldy Western Blots, which are both low throughput and poorly quantitative. Ciphergen’s assay measures directly the product of the enzymatic reaction for ADAMTS13, and provides the level of quantitation necessary to distinguish TTP from other thrombocytopenic diseases.
 
Creating and maintaining a viable product pipeline
 
Ciphergen can develop potential tests based on biomarkers discovered in its sponsored programs with academic collaborators, and also has the opportunity to in-license tests from an installed base of hundreds of academic SELDI customers. Ciphergen’s strategy of selling its SELDI proteomics platform to researchers in academia, pharmaceutical companies, and biotechnology companies may provide Ciphergen with access to biomarkers that could potentially lead to additional diagnostic tests. Going forward, Bio-Rad and Ciphergen have agreed to continue to identify SELDI users that could provide additional biomarker discoveries for Ciphergen’s diagnostics pipeline. In addition, Ciphergen has the opportunity to identify additional markers discovered on other platforms that complement its existing product pipeline.
 
Ciphergen has entered into collaboration, research, and material transfer agreements with more than 16 companies and academic institutions to support its large-scale clinical studies, including ongoing studies as well as studies Ciphergen plans to conduct in the future. Some of Ciphergen’s major collaborations in the areas of cancer and women’s health are described in greater detail here.

Further details regarding important developments in several of Ciphergen’s large-scale studies are set forth below.
 
Ovarian cancer.  Commonly known as the “silent killer,” ovarian cancer leads to approximately 14,000 deaths each year in the United States. Approximately 23,000 new cases are diagnosed each year, with the majority in patients with late stage disease, i.e., when the cancer has spread beyond the ovary. Unfortunately, the prognosis is poor in these patients, leading to the high mortality from this disease. While the diagnosis of ovarian cancer in its earliest stages has a profound positive impact on the likelihood of survival of the disease, another factor that predicts survival from ovarian cancer is the specialty training of the surgeon who operates on the patient with ovarian cancer, with patients being treated by the gynecologic oncologist having better outcomes than those treated by the general surgeon. Accordingly, an unmet clinical need is a diagnostic test that can provide adequate predictive value to stratify patients with a pelvic mass into high risk of invasive ovarian cancer versus those with a low risk. No blood test currently exists to address properly this clinical question, although CA125 is commonly used. CA125, which is cleared by the FDA only for monitoring for recurrence of ovarian cancer, is absent in up to 50% of early stage ovarian cancer cases, and can be elevated in diseases other than ovarian cancer, including benign ovarian tumors and endometriosis. These shortcomings limit CA125’s utility in distinguishing benign from malignant ovarian tumors or for use in detection of early stage ovarian cancer. Transvaginal ultrasound is another diagnostic modality used with patients with ovarian tumors. Attempts at defining specific morphological criteria that can aid in a benign versus malignant diagnosis have led to the morphology index and the risk of malignancy index, with reports of 40-70% predictive value. However, ultrasound interpretation can be variable and dependent on the experience of the operator. In August 2004, Ciphergen along with collaborators at Johns Hopkins, University College London, and M. D. Anderson Cancer Center reported the discovery of three markers that, when combined, provided higher diagnostic accuracy for early stage ovarian cancer than other markers, for example, CA125. The three markers that Ciphergen reported in 2004 form the basis of an expanded panel of biomarkers that together have been demonstrated to provide risk stratification information in a series of studies involving over 2,000 clinical samples from 5 sites. The most recent data, presented at the annual meeting of the American Society of Clinical Oncology in June 2006, demonstrate the portability of this marker panel among different clinical groups, indicating its potential validity across various testing populations. Ciphergen and collaborators at Rigshospitalet (Copenhagen) also reported the results of a prospective clinical trial involving over 200 consecutive women specifically to test the performance of this marker panel in a realistic patient population, and achieved 80% positive predictive value (likelihood that a positive test result is truly invasive epithelial ovarian cancer), better than other available diagnostic modality in this patient cohort. Ciphergen is continuing to investigate the role of these markers, as well as discovering additional biomarkers, that may be used to identify early stage ovarian cancer.
 
Prostate cancer.  Approximately 250,000 men are expected to be diagnosed with prostate cancer in the United States each year, approximately 195,000 of whom will need to make critical decisions on whether or not to undergo local therapy, such as surgery or radiation, and on whether or not to have additional treatment after local therapy. Because the side effects of surgery and local radiation therapy can be serious, a need exists for a reliable test to determine the likelihood of progression. There is also a need for a reliable test to determine the likelihood of recurrence after local treatment, because hormonal therapy and chemotherapy have significant side effects as well. It has become clear that prostate cancer suffers from over-diagnosis in that many men with prostate cancer will not die of the disease, but it is unclear which patients will have an adverse outcome directly related to prostate cancer versus those who will not. In May 2006, Ciphergen and Johns Hopkins reported the discovery of two biomarkers that, when combined with PSA, were highly predictive of likelihood of recurrence of prostate cancer. The results arose from two studies, one examining over 400 men with prostate cancer, and the other examining 50 pairs of men followed for 5 years with prostate cancer matched for age, cancer stage, and other clinical parameters. These results suggest the potential to aid in the stratification of risk of highly aggressive prostate cancer, independent of other clinical variables, reduce overtreatment of prostate cancer cases not likely to be lethal, and shift treatment to those cases that are particularly likely to be lethal.
 
Breast cancer.  Detection of early stage breast cancer holds the potential to improve outcomes for women with this disease. No blood markers currently exist that can accurately detect ductal carcinoma in situ, or DCIS, which is one of the earliest stages of breast cancer, and it is likely that imaging modalities such as mammography, ultrasound, and magnetic resonance imaging will improve detection accuracy when combined with blood markers

or molecular imaging targets. Ciphergen in collaboration with Johns Hopkins has performed two independent studies to identify blood markers for DCIS and stage I breast cancer. The first study examined 169 women with varying stages of breast cancer, benign disease, and healthy women, and the second study examined 176 women from a different medical center as independent validation. Ciphergen is currently performing a 350 woman multi-center validation study to confirm the two markers identified in the previous studies.
 
Peripheral arterial disease.  This disease affects 12 million Americans and is underdiagnosed and undertreated. With the rising incidence of diabetes, the incidence of peripheral arterial disease, or PAD, is expected to increase concomitantly. The absence of a good blood test contributes to the underdiagnosis of PAD. Ciphergen in collaboration with Stanford University has performed both an initial discovery study and a first validation study that has resulted in the identification of a novel biomarker for PAD. Ongoing efforts are aimed at further validating this marker in combination with additional cardiovascular biomarkers.
 
Thrombotic thrombocytopenic purpura.  This disease affects approximately 1,000 Americans annually and is life threatening in the absence of appropriate treatment, which is usually plasmaphoresis. Undertreatment can lead to increased mortality from the disease while overtreatment wastes precious resources. In addition, patients with TTP need to be monitored for clinical response to therapy. Because the pathophysiology of TTP is known to be a result of a defect in the activity of the enzyme ADAMTS13, mass spectrometry was a logical approach to develop an accurate and quantitative assay to measure this enzymatic activity. Final assay development is under way.
 
Assisted reproductive technology.  There has been increased use of ART to facilitate pregnancies, either in women who are infertile or who have waited to have babies. Currently, it is difficult to predict which embryos will lead to viable fetuses and successful live births. Therefore, women may go through multiple cycles of induction and implantation and/or may have multiple embryos implanted. Implantation cycles are expensive, and multiple implantations often result in multiple gestations. Therefore a test that can improve the probability that an implanted embryo will result in a live birth will reduce overall costs associated with ART and may reduce the number of multiple gestations. SELDI-TOF-MS profiling of conditioned media derived from cultured embryos has revealed a series of proteins that may improve in discriminating between embryos that are more likely to successfully implant versus those that are not. These results are currently undergoing validation.
 
Commercialization
 
If we are successful at discovering biomarkers and panels of biomarkers that have diagnostic utility, our commercialization strategy includes partnering with other parties to assist in the development and commercialization of our initial tests. In July, 2005, we entered into a strategic alliance agreement with Quest Diagnostics covering a three year period during which the parties have agreed to develop and commercialize up to three diagnostic tests based on SELDI technology. In connection with this strategic alliance, Quest Diagnostics invested $15 million in Ciphergen and received a warrant to invest an additional $7.7 million. In addition, Quest Diagnostics agreed to loan Ciphergen up to $10 million to pay certain costs and expenses related to the strategic alliance, which loan is forgiveable based upon the achievement of certain milestones related to the development of diagnostic tests.
 
We expect to commercialize and sell diagnostic tests in two phases. The first phase (the “ASR phase”) will involve the sale of analyte specific reagents (“ASR”) to certain customers coupled with the grant to such customer of a sublicense to perform the laboratory test using the methodology covered by the relevant license obtained from our collaborator(s), e.g., a test for ovarian cancer covered by licenses from Johns Hopkins and the M. D. Anderson Cancer Center. ASRs are the raw materials which we will resell or make ourselves and which are utilized by clinical laboratories to develop and perform “homebrew” laboratory tests in CLIA-regulated laboratories (i.e., laboratories regulated under the federal Clinical Laboratory Improvement Amendments of 1988 [“CLIA”]). During the second phase (the “IVD phase”), we plan to assemble and sell in vitro diagnostic, or IVD, test kits, which have been cleared by the FDA, to customers together with SELDI instruments which we expect to purchase from Bio-Rad.
 
Under our strategic alliance agreement, Quest Diagnostics has the exclusive right to perform up to three ASR laboratory tests and, once we begin manufacturing a test kit for each of such tests, we expect that Quest Diagnostics will cease producing the homebrew tests and will purchase FDA-cleared IVD test kits from Ciphergen. Quest Diagnostics will have the exclusive right to perform such test and market test kits purchased from Ciphergen in the United States, Mexico, the United Kingdom and other countries, such as Brazil, where Quest Diagnostics operates a

Table of Contents

clinical laboratory for up to five years following commercialization of each respective test (referred to as the Exclusive Period) with non-exclusive rights to commercialize these tests in the rest of the world, subject to a royalty payable to Ciphergen. Upon expiration of the Exclusive Period, Quest Diagnostics’ exclusive rights will become non-exclusive.
 
During the ASR phase for a given test, and so long as the Exclusive Period continues, we will sell ASRs and grant rights to perform such tests to Quest Diagnostics and to other reference laboratories, hospitals and medical clinics in countries where Quest diagnostics does not operate a clinical laboratory. Once the IVD phase begins for a given test, and so long as the Exclusive Period continues for that particular test, we will sell test kits and instruments to Quest Diagnostics. At the end of the Exclusive Period with respect to any test kit, Quest Diagnostics’ exclusive right to perform tests using such test kit will become non-exclusive. In addition to continuing to sell test kits to Quest Diagnostics, we will then also sell test kits to commercial clinical laboratories in the United States, Mexico, the United Kingdom and other countries which were exclusive to Quest Diagnostics during the Exclusive Period. In addition to working through Quest Diagnostics, Ciphergen intends to seek partnerships for commercialization purposes with traditional in vitro diagnostic companies and/or with clinical reference labs in territories where Quest Diagnostics does not have exclusive rights.
 
Customers
 
Ciphergen expects that Quest Diagnostics and future commercialization partners, reference laboratories, hospitals and medical clinics that perform diagnostic testing will be the primary users of instruments, chips and future diagnostic products which we may develop and that those customers, along with our collaborators, will continue to be the primary users of instruments and arrays that we may develop or sell. Pursuant to the manufacture and supply agreement with Bio-Rad, Bio-Rad has agreed to supply Ciphergen with SELDI instruments and ProteinChip arrays previously manufactured by us. If Bio-Rad develops new products using SELDI technology, Bio-Rad has agreed to supply those products to Ciphergen to sell to its customers. Ciphergen can also request that Bio-Rad develop and manufacture new products to written specifications and the parties will negotiate in good faith the terms of purchasing such products.
 
Competition
 
The diagnostics industry in which Ciphergen operates is competitive and evolving. There is intense competition among healthcare, biotechnology, and diagnostic companies attempting to discover candidates for potential new diagnostic products. These companies may:
 
  •  develop new diagnostic products in advance of Ciphergen or its collaborators;
 
  •  develop diagnostic products which are more effective or more cost-effective than those developed by Ciphergen or its collaborators;
 
  •  obtain regulatory clearance or approval of their diagnostic products more rapidly than Ciphergen or its collaborators; or
 
  •  obtain patent protection or other intellectual property rights that would limit Ciphergen’s or its collaborators’ ability to develop and commercialize, or their customers’ ability to use, Ciphergen’s, or its collaborators’, diagnostic products.
 
Ciphergen competes with companies in the U.S. and abroad that are engaged in the development and commercialization of novel biomarkers that may form the basis of novel diagnostic tests. These companies may develop products that are competitive with the products offered by Ciphergen or its collaborators, such as analyte specific reagents or diagnostic test kits, that perform the same or similar purposes as Ciphergen’s or its collaborators’ products. Also, clinical laboratories may offer testing services that are competitive with the products sold by Ciphergen or its collaborators. For example, a clinical laboratory can use either reagents purchased from manufacturers other than Ciphergen, or use its own internally developed reagents, to make diagnostic tests. If clinical laboratories make tests in this manner for a particular disease, they could offer testing services for that disease as an alternative to products sold by Ciphergen used to test for the same disease. The testing services offered by clinical laboratories may be easier to develop and market than test kits developed by Ciphergen or its

collaborators because the testing services are not subject to the same clinical validation requirements that are applicable to FDA-cleared or approved diagnostic test kits. The diagnostic testing services market is estimated to be approximately $40 billion. A substantial portion of all sales of diagnostic products are made to a small number of clinical reference laboratories such as Quest Diagnostics Incorporated and Laboratory Corporation of America Holdings, which together account for close to 20% of the testing services market. Therefore, Ciphergen expects to rely on clinical reference laboratories for a substantial portion of its sales. Ciphergen’s inability to establish or maintain one or more of these laboratories as a customer could adversely affect its business, financial condition, and operating results.
 
Research and Development
 
Ciphergen’s research and development efforts towards developing novel high-value diagnostic tests focus on two synergistic activities. First, Ciphergen is dedicated to developing new approaches to investigate the human proteome. Second, Ciphergen utilizes these new technologies to discover biomarkers that can address unmet clinical needs. A major area of our research and development activities centers around efforts to discover and validate biomarkers and patterns of biomarkers that can be developed into diagnostic assays. We do this both through in-house programs and through collaborations we have established with The Johns Hopkins School of Medicine, The University of Texas M. D. Anderson Cancer Center and University College London, among others.
 
In applied research, we are developing new applications and reagents for quantitative differential protein expression analysis, protein interaction assays and protein characterization. Our efforts are particularly focused on discovery and quantitative analysis of low-abundance proteins present in complex samples such as plasma, serum and urine. We have demonstrated that the surface chemistries immobilized on ProteinChip Arrays have similar protein selectivity to those chemistries immobilized on higher capacity bead formats, facilitating the transition from discovery on arrays to small scale purification on beads as well as orthogonal purification. Using these approaches, we seek to improve the speed and efficiency of designing protein separation strategies at any scale based on the predictive information obtained using ProteinChip Systems. We believe these methods will accelerate the identification of discovered biomarkers.
 
Ciphergen’s activities in research and development will maintain a strong focus in protein separation technologies, but will be intently focused on development (i.e., taking research tools and developing them into practical, usable tools for biomarker discovery and assay). Research will initially focus on three major tasks:
 
  •  Making Equalizertm bead technology practical for biomarker discovery
 
  •  Making multi-select technology practical for biomarker discovery
 
  •  Clinical assay development using novel proteomics technologies
 
These objectives will maintain Ciphergen’s competitive edge in biomarker discovery abilities, and will be critical in our ability to improve on our current diagnostic tests under development as well as to develop and foster a pipeline of diagnostic tests. The new proteomic analysis tools that Ciphergen has developed are intended to provide Ciphergen an important advantage in the race to discover novel biomarkers. The complexity of the human proteome has hindered efforts to develop a comprehensive database of expressed proteins and their post-translational modifications. Consequently, entities that are able to leverage novel protein separation tools will have an advantage in analyzing clinical samples to identify biomarkers for disease. Ciphergen has focused on developing solutions to the problem of separating proteins to increase the number of proteins that can be detected and characterized while maintaining a level of throughput that permits running enough numbers of clinical samples to achieve statistical significance. These novel solutions are embodied in tools such as Equalizer Beads and multi-select and mini-select technologies. These tools have been applied to clinical samples that may be used to address diagnostic questions in hematology/oncology, women’s health, and cardiovascular disease, as described above.
 
Intellectual Property
 
Our intellectual property includes a portfolio of owned, co-owned or licensed patents and patent applications. As of July 31, 2006, our patent portfolio included 36 issued U.S. patents, 100 pending U.S. patent applications and numerous pending patent applications and issued patents outside the U.S. These patents and patent applications are


B-11


Table of Contents

directed to several areas of technology important to our business, including the core SELDI technology and its applications, protein biochips, instrumentation, software and biomarkers. The issued patents covering the SELDI and Retentate Chromatography mass spectrometry technologies expire at various times from 2013 to 2019. Pursuant to the asset purchase agreement, Bio-Rad acquired certain proprietary rights used in the research tools business. At the closing of the asset purchase, we will enter into a cross license agreement with Bio-Rad pursuant to which we will retain the right to commercially exploit those proprietary rights, including SELDI technology, in the clinical diagnostics market. The clinical diagnostics market includes laboratories engaged in the research and development and/or manufacture of diagnostic tests using biomarkers, commercial clinical laboratories, hospitals and medical clinics that perform diagnostic tests. Ciphergen has been granted exclusive rights to commercialize the proprietary rights in the clinical diagnostics market during a five-year exclusivity period. After the end of the five-year period, we and Bio-Rad will share exclusive rights. Ciphergen and Bio-Rad each have the right to engage in negotiations with the other party for a license to any improvements in the proprietary rights created by the other party.
 
The rights to the core SELDI technology are derived through royalty-bearing sublicenses from Molecular Analytical Systems, Inc., or MAS. MAS holds an exclusive license to patents directed to the SELDI technology from the owner, Baylor College of Medicine. MAS granted certain rights under these patents to our wholly owned subsidiaries, IllumeSys Pacific, Inc. and Ciphergen Technologies, Inc. in 1997. We obtained further rights under the patents in 2003 through sublicenses and assignments executed as part of the settlement of a lawsuit between Ciphergen, MAS, LumiCyte and T. William Hutchens. Together, the sublicenses and assignments provide all rights to develop, make and have made, use, sell, import, market and otherwise exploit products and services covered by the patents throughout the world in all fields and applications, both commercial and non-commercial. The sub licenses carry the obligation to pay MAS a royalty equal to 2% of SELDI-related revenues recognized between February 21, 2003 and the earlier of (i) May 28, 2014, or (ii) the date on which the cumulative payments to MAS have reached $10,000,000. Through June 30, 2006, we had paid or accrued a total of approximately $2.5 million in such royalties.
 
We hold licenses or options to license biomarkers developed using SELDI technology, and related intellectual property. As of July 31, 2006, 41 of our patent applications are directed to biomarker inventions. These include applications in the areas of cancer, cardiovascular disease, infectious disease, neurodegenerative disease and women’s health. We are currently negotiating an extension of the term of our collaboration agreement with The Johns Hopkins School of Medicine to patent applications directed to biomarkers for ovarian cancer that we intend to commercialize as an ovarian cancer diagnostic test. Other institutions and companies from which we hold options to license intellectual property related to biomarkers include University College London (England), The University of Texas M. D. Anderson Cancer Center, University of Kentucky, McGill University (Canada), Eastern Virginia Medical School, Aaron Diamond AIDS Research Center, The University of Texas Medical Branch, Göteborg University (Sweden), University of Kuopio (Finland) and the Netherlands Cancer Institute (Netherlands).
 
Manufacturing
 
Assuming shareholder approval of the asset sale to Bio-Rad, Bio-Rad will take over Ciphergen’s manufacturing operations and pursuant to the manufacture and supply agreement with Bio-Rad, Bio-Rad has agreed to manufacture and Ciphergen has agreed to purchase from Bio-Rad the ProteinChip Systems and ProteinChip Arrays (collectively referred to as the research tools products) required to support its diagnostics efforts. If Bio-Rad fails to supply any research tools products to Ciphergen, including any new research tools products developed by Bio-Rad for sale to its customers or any new research tools products Ciphergen has requested Bio-Rad to make and sell to Ciphergen, under certain conditions Ciphergen has the right to manufacture or have such research tools products manufactured by a third party for Ciphergen’s own use and sale to its customers and collaborators in the clinical diagnostics market, subject to payment of a reasonable royalty to Bio-Rad on sales of such research tools products. In the event that Bio-Rad is unable to provide the ProteinChip instruments, arrays and supplies as required, there is no guarantee that we will be able to find such a third party supplier, or that the cost of purchasing these items will be commercially reasonable. If we are not able to obtain the necessary ProteinChip instruments, arrays, and supplies, our ability to develop diagnostic products will be adversely affected.

Ciphergen will be responsible for assuring through its incoming quality control process that the research tools products it purchases from Bio-Rad will comply with applicable government regulations. During 2005, Ciphergen enhanced its quality control systems in order to comply with U.S. Food and Drug Administration, or FDA, regulations; that compliance has been reviewed through an independent audit. Ciphergen believes it is prepared to fulfill its obligation to assure that such research tools products are in compliance with the FDA’s Quality System Regulations, or QSRs, in 2006.
 
Environmental Matters
 
Medical Waste
 
We are subject to licensing and regulation under federal, state and local laws relating to the handling and disposal of medical specimens and hazardous waste as well as to the safety and health of laboratory employees. Our laboratory facility in Fremont, California is operated in material compliance with applicable federal and state laws and regulations relating to disposal of all laboratory specimens. We utilize outside vendors for disposal of specimens. We cannot eliminate the risk of accidental contamination or discharge and any resultant injury from these materials. Federal, state and local laws and regulations govern the use, manufacture, storage, handling and disposal of these materials. We could be subject to damages in the event of an improper or unauthorized release of, or exposure of individuals to, hazardous materials. In addition, claimants may sue us for injury or contamination that results from our use, or the use by third parties, of these materials, and our liability may exceed our total assets. Compliance with environmental laws and regulations is expensive, and current or future environmental regulations may impair our research, development or production efforts.
 
Occupational Safety
 
In addition to its comprehensive regulation of safety in the workplace, the Federal Occupational Safety and Health Administration has established extensive requirements relating to workplace safety for healthcare employers, including clinical laboratories, whose workers may be exposed to blood-borne pathogens such as HIV and the hepatitis virus. These regulations, among other things, require work practice controls, protective clothing and equipment, training, medical follow-up, vaccinations and other measures designed to minimize exposure to chemicals and transmission of the blood-borne and airborne pathogens. Although we believe that we are currently in compliance in all material respects with such federal, state and local laws, failure to comply could subject us to denial of the right to conduct business, fines, criminal penalties and other enforcement actions.
 
Specimen Transportation
 
Regulations of the Department of Transportation, the International Air Transportation Agency, the Public Health Service and the Postal Service apply to the surface and air transportation of clinical laboratory specimens.
 
Government Regulation
 
General
 
Our future activities related to diagnostics products are, or have the potential to be, subject to regulatory oversight by the FDA under provisions of the Federal Food, Drug and Cosmetic Act and regulations thereunder, including regulations governing the development, marketing, labeling, promotion, manufacturing and export of our products. Failure to comply with applicable requirements can lead to sanctions, including withdrawal of products from the market, recalls, refusal to authorize government contracts, product seizures, civil money penalties, injunctions and criminal prosecution.
 
Generally, certain categories of medical devices, a category that may be deemed to include potential future products based upon the ProteinChip® platform, may require FDA 510(k), or 510(k) de novo clearance or pre-market approval. Although the FDA believes it has jurisdiction to regulate in-house laboratory tests, or “home brews,” that have been developed and validated by the laboratory providing the tests, the FDA has not, to date, actively regulated those tests. “Active ingredients” (known as “analyte specific reagents” or “ASRs”) that are sold to laboratories for use in tests developed in house by clinical laboratories generally do not require FDA approval or


B-13


Table of Contents

clearance. ASRs generally do not require FDA clearance or pre-market approval if they are (1) sold to clinical laboratories certified by the government to perform high complexity testing, (2) manufactured in compliance with the FDA’s QSRs, and (3) labeled in accordance with FDA requirements, including a statement that their analytical and performance characteristics have not been established. A similar statement would also be required on all advertising and promotional materials relating to ASRs, such as those used in certain of our proposed future tests. We believe that clinical laboratory testing based upon our ProteinChip platform, and any ASRs that we intend to sell to clinical reference laboratories, currently would not require FDA clearance or approval. The FDA has publicly stated it is reevaluating its ASR policy, and it is possible that future revisions to FDA policies may have the effect of increasing the regulatory burden on manufacturers of these devices. The commercialization of our products and services could be impacted by being delayed, halted or prevented. We cannot be sure that tests based upon the ProteinChip platform, or a combination of reagents, will not require FDA 510(k), 510(k) de novo clearance or pre-market approval.
 
Regardless of whether a medical device requires FDA approval or clearance, a number of other FDA requirements apply to the manufacturer of such a device and to those who distribute it. Device manufacturers must be registered and their products listed with the FDA, and certain adverse events, corrections and removals must be reported to the FDA. The FDA also regulates the product labeling, promotion and, in some cases, advertising of medical devices. Manufacturers must comply with the FDA’s QSRs, which establish extensive requirements for design, quality control, validation and manufacturing. Thus, manufacturers and distributors must continue to spend time, money and effort to maintain compliance, and failure to comply can lead to enforcement action. The FDA periodically inspects facilities to ascertain compliance with these and other requirements.
 
Diagnostic Kits
 
The Food, Drug and Cosmetic Act requires that medical devices introduced to the U.S. market, unless exempted by regulation, be the subject of either a premarket notification clearance, known as a 510(k) or (510(k) de novo, or a premarket approval, known as a PMA. Some of our potential future clinical products may require a 510(k) or (510(k) de novo, others may require a PMA. Other products, like ASRs, may be exempt from regulatory clearance or approval.
 
With respect to devices reviewed through the 510(k) process, we may not market a device until an order is issued by the FDA finding our product to be substantially equivalent to a legally marketed device known as a predicate device. A 510(k) submission may involve the presentation of a substantial volume of data, including clinical data. The FDA may agree that the product is substantially equivalent to a predicate device and allow the product to be marketed in the U.S. On the other hand, the FDA may determine that the device is not substantially equivalent and require a PMA, or require further information, such as additional test data, including data from clinical studies, before it is able to make a determination regarding substantial equivalence. By requesting additional information, the FDA can further delay market introduction of our products.
 
If the FDA indicates that a PMA is required for any of our potential future clinical products, the application will require extensive clinical studies, manufacturing information and likely review by a panel of experts outside the FDA. Clinical studies to support either a 510(k) submission or a PMA application would need to be conducted in accordance with FDA requirements. Failure to comply with FDA requirements could result in the FDA’s refusal to accept the data or the imposition of regulatory sanctions. There can be no assurance that we will be able to meet the FDA’s requirements or receive any necessary approval or clearance.
 
Once granted, a 510(k) clearance or PMA approval may place substantial restrictions on how our device is marketed or to whom it may be sold. Even in the case of devices like ASRs, many of which are exempt from 510(k) clearance or PMA approval requirements, the FDA may impose restrictions on marketing. Our potential future ASR products may be sold only to clinical laboratories certified under CLIA to perform high complexity testing. In addition to requiring approval or clearance for new products, the FDA may require approval or clearance prior to marketing products that are modifications of existing products or the intended uses of these products. We cannot assure that any necessary 510(k) clearance or PMA approval will be granted on a timely basis, or at all. Delays in receipt of or failure to receive any necessary 510(k) clearance or PMA approval, or the imposition of stringent restrictions on the labeling and sales of our products, could have a material adverse effect on us.

As a medical device manufacturer, we are also required to register and list our products with the FDA. In addition, we are required to comply with the FDA’s QSRs, which require that our devices be manufactured and records be maintained in a prescribed manner with respect to manufacturing, testing and control activities. Further, we are required to comply with FDA requirements for labeling and promotion. For example, the FDA prohibits cleared or approved devices from being promoted for uncleared or unapproved uses. In addition, the medical device reporting regulation requires that we provide information to the FDA whenever there is evidence reasonably to suggest that one of our devices may have caused or contributed to a death or serious injury, or where a malfunction has occurred that would be likely to cause or contribute to a death or serious injury if the malfunction were to recur.
 
Our manufacturing facilities are subject to periodic and unannounced inspections by the FDA and state agencies for compliance with QSRs. Additionally, the FDA will generally conduct a preapproval inspection for PMA devices. Although we believe we will be able to operate in compliance with the FDA’s QSRs for ASRs, we have never been inspected by the FDA and cannot assure that we will be able to maintain compliance in the future. If the FDA believes that we are not in compliance with applicable laws or regulations, it can issue a warning letter, detain or seize our products, issue a recall notice, enjoin future violations and assess civil and criminal penalties against us. In addition, approvals or clearances could be withdrawn under certain circumstances. Failure to comply with regulatory requirements or any adverse regulatory action could have a material adverse effect on us.
 
Any customers using our products for clinical use in the U.S. may be regulated under CLIA. CLIA is intended to ensure the quality and reliability of clinical laboratories in the U.S. by mandating specific standards in the areas of personnel qualifications, administration, participation in proficiency testing, patient test management, quality control, quality assurance and inspections. The regulations promulgated under CLIA establish three levels of diagnostic tests — namely, waived, moderately complex and highly complex — and the standards applicable to a clinical laboratory depend on the level of the tests it performs. We cannot assure you that the CLIA regulations and future administrative interpretations of CLIA will not have a material adverse impact on us by limiting the potential market for our potential future products.
 
Medical device laws and regulations are also in effect in many of the countries in which we may do business outside the U.S. These range from comprehensive device approval requirements for some or all of our potential future medical device products, to requests for product data or certifications. The number and scope of these requirements are increasing. Medical device laws and regulations are also in effect in some states in which we do business. There can be no assurance that we will obtain regulatory approvals in such countries or that we will not incur significant costs in obtaining or maintaining foreign regulatory approvals. In addition, export of certain of our products which have not yet been cleared or approved for domestic commercial distribution may be subject to FDA export restrictions.
 
Employees
 
As of July 31, 2006, we had 140 full-time employees worldwide, including 64 in sales and marketing, 26 in research and development, 30 in manufacturing and 20 in administration. We also had an additional 17 individuals engaged as independent contractors. None of our U.S. employees is covered by a collective bargaining agreement, though many of our European employees are covered under national labor agreements. We believe that our relations with our employees are good. Ciphergen’s success will depend in large part on our ability to attract and retain skilled and experienced employees. Following the closing of the Bio-Rad transaction, we expect initially to have approximately 40 full-time employees.

ANNEX C: FAIRNESS OPINION
 
OPPENHEIMER LTTRHD

Confidential
Board of Directors
Ciphergen Biosystems, Inc.
6611 Dumbarton Circle
Fremont CA, 94555
 
Members of the Board of Directors:
 
We have been engaged to evaluate the fairness, from a financial point of view, to the holders of outstanding shares of the common stock of Ciphergen Biosystems, Inc., a Delaware Corporation (“Ciphergen” or the “Company”), of the proposed sale (the “Sale”) of the assets of Ciphergen’s tools business to Bio-Rad Laboratories, Inc (“Bio-Rad”) for the consideration (the “Sale Consideration”) as per the agreement between Ciphergen and Bio-Rad (the “Asset Purchase Agreement”).
 
In arriving at our opinion (the “Opinion”), we have had numerous discussions with management about Ciphergen’s operations, financial condition and prospects with respect to both its tools business and its diagnostics business. We have reviewed the Asset Purchase Agreement, including the schedules and exhibits thereto, and analyzed financial and other information that was publicly available or furnished to us by the Company, including information provided to us during discussions with the management of Ciphergen. Included in the information provided during such discussions were historical audited financial data of Ciphergen and certain financial projections of Ciphergen and its tools business prepared by its management. In addition, we have compared certain financial data of Ciphergen’s tools business with various other companies in generally similar industries with generally similar business and financial characteristics whose securities are traded in public markets and conducted such other financial studies and analyses as we deemed appropriate for purposes of this Opinion. We did not rely on any one particular financial analysis or methodology, but formulated our Opinion on the whole of such analyses.
 
In rendering our Opinion, we have assumed that the Sale will be consummated on all material terms described in the Asset Purchase Agreement. We have relied upon and assumed, without independent verification, the accuracy and completeness of all the financial and other information that was reviewed by us, whether obtained from public sources or provided to us by the Company. In particular, we have relied upon the estimates and projections of the management of Ciphergen, which was the basis of our financial model for the Company. With respect to the financial projections supplied to us, we have assumed that the forecasts presented to us by the management team of the Company were reasonably prepared in good faith and reasonably reflect the best currently available estimates and judgments of the management of Ciphergen regarding the future operating and financial performance of the Company and its tools business. In addition, we have not assumed any responsibility for making any independent evaluation or appraisal of the assets or liabilities of the Company. Oppenheimer has not engaged in any legal analysis or review of the Agreement itself nor had any such analysis or review conducted on its behalf and has assumed that all legal requirements for consummation of the Sale have or will be complied with. We express no view as to the federal, state or local tax consequences of the Sale Consideration or to the accounting treatment of the Sale.
 
We express no view as to, and our Opinion does not address, the underlying business decision of Ciphergen to effect the Sale nor were we requested to consider the relative merits of the Sale as compared to any other transaction in which Ciphergen might engage.

Our Opinion is based on economic, market, financial and other conditions as they currently exist, and on the information made available to us as of the date of this letter, and is limited to the fairness, as of the date hereof, from a financial point of view, of the Sale Consideration. It should be understood that, although subsequent developments may affect this Opinion, we do not have any obligation to update, revise or reaffirm this Opinion.
 
Oppenheimer, as part of its investment banking services, is regularly engaged in the valuation of businesses and securities in connection with mergers, acquisitions, underwritings, sales and distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. Oppenheimer will receive a fee for rendering this Opinion. The Company has agreed to indemnify Oppenheimer under certain circumstances.
 
In the ordinary course of our business, Oppenheimer may actively trade securities of the Company for its own account and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.
 
It is understood that this Opinion has been prepared solely for the use of the Board of Directors of the Company and may not be disclosed, summarized, excerpted from or otherwise publicly referred to, or used for any other purposes without Oppenheimer’s prior written consent, except that the Company may provide a copy of this as described below.

In addition, Oppenheimer will, if requested by the Company, provide such additional reasonable and customary disclosure in connection with such public filings regarding its engagement with the Company, the basis of its Opinion and compensation.
 
Based upon the foregoing and such factors as we deemed relevant, we are of the Opinion that, as of the date hereof, the Sale Consideration is fair from a financial point of view to the shareholders of Ciphergen.
