RISK FACTORS AND FORWARD-LOOKING STATEMENTS

Risks Related to Our Business

We are a biopharmaceutical company with no revenue generating operations and high investment costs.

     We expect to incur losses for a number of years as we continue our research and development projects. There is no assurance that our current level of funds will be sufficient to support all research expenses to achieve commercialization of any of our product candidates. On November 26, 2003, we sold all of our revenue generating operations. We are now focused on developing and testing the product candidates in our Chrysalin Product Platform and have allocated most of our resources to bringing these product candidates to the market. However, on February 27, 2006 we acquired the rights to AZX100, and we also intend to continue preclinical activities on AZX100 in 2006. We may invest in other peptide or small molecule-based therapeutics in the future, but there can be no assurance that opportunities of this nature will occur at acceptable terms, conditions or timing. We currently have no pharmaceutical products being sold or ready for sale and do not expect to be able to introduce any pharmaceutical products for at least several years. As a result of our significant research and development, clinical development, regulatory compliance and general and administrative expenses and the lack of any products to generate revenue, we expect to incur losses for at least the next several years and expect our losses will increase as we continue our research and development activities and incur significant expenses for clinical trials. Our cash reserves, including the cash received from the sale of our bone growth stimulation device business in November 2003, are the primary source of our working capital. There can be no assurance that our cash resources will be sufficient to cover our future operating requirements, or should there be a need, other sources of cash will be available, or if available, at acceptable terms.

     We do not expect to receive any revenue from product sales until we receive regulatory approval and begin commercialization of our product candidates. We cannot predict when that will occur or if it will occur.

     We caution that our future cash expenditure levels are difficult to forecast because the forecast is based on assumptions about the number of research projects we pursue, the pace at which we pursue them, the quality of the data collected and the requests of the FDA to expand, narrow or conduct additional clinical trials and analyze data. Changes in any of these assumptions can change significantly our estimated cash expenditure levels.

Our product candidates are in various stages of development and may not be successfully developed or commercialized.

     If we fail to commercialize our product candidates, we will not be able to generate revenue. We currently do not sell any products. Our product candidates are at the following stages of development:

		•		Acceleration of Fracture Repair		Phase 3 / Phase 2b human clinical trials
		•		Diabetic Foot Ulcer Healing		Phase 1/2 human clinical trials
		•		Spine Fusion Phase		1/2 pilot human clinical trials
		•		Cartilage Defect Repair		Late stage pre-clinical trials
		•		Tendon Repair		Early stage pre-clinical trials
		•		Cardiovascular Repair		Pre-clinical trials
		•		Dental Bone Repair		Pre-clinical trials
		•		AZX100		Pre-clinical testing

     We are subject to the risk that:

	•		the FDA finds some or all of our product candidates ineffective or unsafe;
	•		we do not receive necessary regulatory approvals;
	•		we are unable to get some or all of our product candidates to market in a timely manner;
	•		we are not able to produce our product candidates in commercial quantities at reasonable costs;
	•		our products undergo post-market evaluations resulting in marketing restrictions or withdrawal of our products; or

•

the patients, insurance and/or physician community does not accept our products.

     In addition, our product development programs may be curtailed, redirected or eliminated at any time for many reasons, including:

	•		adverse or ambiguous results;
	•		undesirable side effects which delay or extend the trials;
	•		inability to locate, recruit, qualify and retain a sufficient number of patients for our trials;
	•		regulatory delays or other regulatory actions;
	•		difficulties in obtaining sufficient quantities of the particular product candidate or any other components needed for our pre-clinical testing or clinical trials;
	•		change in the focus of our development efforts; and
	•		re-evaluation of our clinical development strategy.

     We cannot predict whether we will successfully develop and commercialize any of our product candidates. If we fail to do so, we will not be able to generate revenue.

Certain results from a Phase 3 clinical trial showed that the differences in the primary endpoint analyses between our lead compound, Chrysalin, and the placebo were not statistically significant.

     On March 15, 2006, we reported results of our Phase 3 fracture repair human clinical trial. For the primary endpoint, immobilization removal, no statistically significant difference between placebo and a single injection of Chrysalin were achieved. Consistent with the Phase 1/2 human clinical trial results, a statistically significant difference for a secondary endpoint, radiographic evidence of radial cortical bridging, was achieved. However, no statistically significant difference was noted in the study’s other secondary endpoints. These results may make it more difficult to achieve regulatory approval of Chrysalin. On March 15, 2006, we temporarily interrupted enrollment in our Phase 2b fracture repair dosing clinical trial to perform an interim analysis of the data of the 273 patients enrolled to that date. We plan to announce the results of the interim analysis and our future fracture repair indication plans by the 3rd Quarter of 2006.

The results of our late stage clinical trials may be insufficient to obtain FDA approval, which could result in a substantial delay in our ability to generate revenue.

     Positive results from pre-clinical studies and early clinical trials do not ensure positive results in more advanced clinical trials. If we are unable to demonstrate that a product candidate will be safe and effective in advanced clinical trials involving larger numbers of patients, we will be unable to submit the NDA necessary to receive approval from the FDA to commercialize that product.

     On March 15, 2006, as discussed in the risk factor above, we reported results of our Phase 3 fracture repair human clinical trial. For the primary endpoint, immobilization removal, no statistically significant difference between placebo and a single injection of Chrysalin were achieved. Consistent with the Phase 1/2 human clinical trial results, a statistically significant difference for a secondary endpoint, radiographic evidence of radial cortical bridging, was achieved. However, no statistically significant difference was noted in the study’s other secondary endpoints. These results may make it more difficult to achieve regulatory approval of Chrysalin. On March 15, 2006, we temporarily interrupted enrollment in our Phase 2b fracture repair dosing clinical trial to perform an interim analysis of the 273 patients enrolled up to that date. We plan to announce the results of the interim analysis and our future fracture repair indication plans by the 3^rd Quarter of 2006.

     Upon receipt of the interim analysis of the results of our Phase 2b fracture repair dosing clinical trial we will have to determine whether to redesign our Chrysalin fracture repair product candidate and our protocols and continue with additional testing, or cease activities in this area. Redesigning the product candidate could be extremely costly and time-consuming. A substantial delay in obtaining FDA approval or termination of the Chrysalin fracture repair product candidate could result in a delay in our ability to generate revenue and could have a material adverse effect on our business going forward.

The majority of our product candidates are based on the same chemical peptide, Chrysalin. If one of our Chrysalin product candidates reveals safety or fundamental inefficacy issues in clinical trials, it could impact the development path for all our other current Chrysalin product candidates.

     The development of each of our product candidates in the Chrysalin Product Platform is based on our knowledge and understanding of how the human thrombin molecule contributes to the repair of soft tissue and bone. While there are important differences in each of the product candidates in terms of their purpose (fracture repair, diabetic foot ulcer, etc.), each product candidate is focused on accelerating the repair of soft tissue and bone and is based on the ability of Chrysalin to mimic specific attributes of the human thrombin molecule to stimulate the body’s natural healing processes.

     Since we are developing the product candidates in the Chrysalin Product Platform in parallel, we expect to learn from the results of each trial and apply some of our findings to the development of the other product candidates in the platform. The fact that the results from the Phase 3 fracture repair human clinical trial showed no statistical significance between Chrysalin and the placebo for the primary endpoint in the study will likely impact the development path or future development of the other product candidates in the platform, the impact of which will depend on the results of our interim analysis. In addition, if we find that one of our biopharmaceutical product candidates is unsafe in the future, it could impact the development of our other product candidates in clinical trials.

Patients may discontinue their participation in our clinical studies, which may negatively impact the results of these studies and extend the timeline for completion of our development programs.

     As with all clinical trials, we are subject to the risk that patients enrolled in our clinical studies may discontinue their participation at any time during the study as a result of a number of factors, including, withdrawing their consent or experiencing adverse clinical events, which may or may not be judged related to our product candidates under evaluation. We are subject to the risk that if a large number of patients in any one of our studies discontinue their participation in the study, the results from that study may not be positive or may not support an NDA for regulatory approval of our product candidates.

     In addition, the time required to complete clinical trials is dependent upon, among other factors, the rate of patient enrollment. Patient enrollment is a function of many factors, including:

	•		the size of the patient population;
	•		the nature of the clinical protocol requirements;
	•		the diversion of patients to other trials or marketed therapies;
	•		our ability to recruit and manage clinical centers and associated trials;
	•		the proximity of patients to clinical sites; and
	•		the patient eligibility criteria for the study.

Even if we obtain marketing approval, our products will be subject to ongoing regulatory oversight, which may affect our ability to successfully commercialize any products we may develop.

     Even if we receive regulatory approval of a product candidate, the approval may be subject to limitations on the indicated uses for which the product is marketed or require costly post-marketing follow-up studies. After we obtain marketing approval for any product, the manufacturer and the manufacturing facilities for that product will be subject to continual review and periodic inspections by the FDA and other regulatory agencies. The subsequent discovery of previously unknown problems with the product, or with the manufacturer or facility, may result in restrictions on the product or manufacturer, including withdrawal of the product from the market.

     If we fail to comply with applicable regulatory requirements, we may be subject to fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

If we cannot protect the Chrysalin patents, the AZX100 license and patents, or our intellectual property generally, our ability to develop and commercialize our products will be severely limited.

     Our success will depend in part on our ability to maintain and enforce patent protection for Chrysalin and AZX100 and each product resulting from Chrysalin or AZX100. Without patent protection, other companies could offer substantially identical products for sale without incurring the sizable discovery, development and licensing costs that we have incurred. Our ability to recover these expenditures and realize profits upon the sale of products would then be diminished.

     Chrysalin and AZX100 are patented and there have been no successful challenges to the patents. However, if there were to be a challenge to these patents or any of the patents for product candidates, a court may determine that the patents are invalid or unenforceable. Even if the validity or enforceability of a patent is upheld by a court, a court may not prevent alleged infringement on the grounds that such activity is not covered by the patent claims. Any litigation, whether to enforce our rights to use our or our licensors’ patents or to defend against allegations that we infringe third party rights, will be costly, time consuming, and may distract management from other important tasks.

     As is commonplace in the biotechnology and pharmaceutical industry, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. To the extent our employees are involved in research areas which are similar to those areas in which they were involved at their former employers, we may be subject to claims that such employees and/or we have inadvertently or otherwise used or disclosed the alleged trade secrets or other proprietary information of the former employers. Litigation may be necessary to defend against such claims, which could result in substantial costs and be a distraction to management and which may have a material adverse effect on us, even if we are successful in defending such claims.

     We also rely in our business on trade secrets, know-how and other proprietary information. We seek to protect this information, in part, through the use of confidentiality agreements with employees, consultants, advisors and others. Nonetheless, we cannot assure that those agreements will provide adequate protection for our trade secrets, know-how or other proprietary information and prevent their unauthorized use or disclosure. The risk that other parties may breach confidentiality agreements or that our trade secrets become known or independently discovered by competitors, could adversely affect us by enabling our competitors, who may have greater experience and financial resources, to copy or use our trade secrets and other proprietary information in the advancement of their products, methods or technologies.

Our success also depends on our ability to operate and commercialize products without infringing on the patents or proprietary rights of others.

     Third parties may claim that we or our licensors or suppliers are infringing their patents or are misappropriating their proprietary information. In the event of a successful claim against us or our licensors or suppliers for infringement of the patents or proprietary rights of others, we may be required to, among other things:

	•		pay substantial damages;
	•		stop using our technologies;
	•		stop certain research and development efforts;
	•		develop non-infringing products or methods; and
	•		obtain one or more licenses from third parties.

     A license required under any such patents or proprietary rights may not be available to us, or may not be available on acceptable terms. If we or our licensors or suppliers are sued for infringement, we could encounter substantial delays in, or be prohibited from, developing, manufacturing and commercializing our product candidates.

Some of our product candidates are in early stages of development and may never be commercialized.

     Research, development and pre-clinical testing are long, expensive and uncertain processes. Other than indications for fracture repair, spine fusion, and diabetic ulcer healing, none of our other Chrysalin or AZX100

product candidates has reached clinical trial testing. Our development of Chrysalin for the repair of cartilage defects, tendons and cardiovascular repair is currently in pre-clinical testing or the research stage and AZX100 is currently in the pre-clinical testing stage. Our future success depends, in part, on our ability to complete pre-clinical development of these and other product candidates and advance them to the clinical trials.

     If we are unsuccessful in advancing our early stage product candidates into clinical testing for any reason, our business prospects will be harmed.

Acquisition of New Class of Molecules, ICARMs™

     On February 23, 2006, we entered into an agreement to purchase certain assets and assume certain liabilities of AzERx, Inc. for $390,000 in cash and the issuance of 1,355,000 shares of our common stock, with a market value of $7.7 million determined by the closing share price on the date the agreement was entered into. The transaction was completed (closed) on February 27, 2006. Under the terms of the transaction, OrthoLogic acquired an exclusive license for the core intellectual property relating to AZX100, and will continue to develop the new class of compounds in the field of smooth muscle relaxation called Intracellular Actin Relaxing Molecules, or ICARMs™, based on the unique technology developed by AzERx. The acquisition provides us with a new technology platform that diversifies the portfolio, and may provide more than one potential product. AzERx’s lead compound is AZX100, a 24-amino acid peptide. AZX100 is currently being investigated for medically important and commercially significant applications such as the treatment of vasospasm associated with subarachnoid hemorrhage, prevention of keloid scarring, and the treatment of asthma. Preclinical and human in vitro studies have shown that this novel compound has the ability to relax smooth muscle in multiple tissue types. While we performed a reasonable level of due diligence on AZX100 and the rights acquired, there can be no assurances that we will recover the costs of our investment from the future development of AZX100 or that commercially significant applications will be developed.

The loss of our key management and scientific personnel may hinder our ability to execute our business plan.

     As a small company our success depends on the continuing contributions of our management team and scientific personnel, and maintaining relationships with the network of medical and academic centers in the United States that conduct our clinical trials. On April 5, 2006, James M. Pusey resigned as our President and Chief Executive Officer and as a director. The resignation or retirement of additional members of senior management or scientific personnel could materially adversely affect our business prospects.

Reliance on Outside Suppliers and Consultants

     We rely on outside suppliers and consultants for the manufacture of Chrysalin and AZX100 and technical assistance in our research and development efforts. The inability of our suppliers to meet our production quality requirements in a timely manner, or the lack of availability of experienced consultants to assist in our research and development efforts, could have a material effect on our ability to perform research or clinical trials.

We face an inherent risk of liability in the event that the use or misuse of our products results in personal injury or death.

     The use of our product candidates in clinical trials, and the sale of any approved products, may expose us to product liability claims, which could result in financial losses. Our clinical liability insurance coverage may not be sufficient to cover claims that may be made against us. In addition, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts or scope to protect us against losses. Any claims against us, regardless of their merit, could severely harm our financial condition, strain our management and other resources and adversely impact or eliminate the prospects for commercialization of the product which is the subject of any such claim.

Risks of our Industry

We are in a highly regulated field with high investment costs and high risks.

     Our Chrysalin Product Platform is currently in the human testing phase for three potential products and earlier pre-clinical testing phases for two other potential products. AZX100 is currently in pre-clinical testing. The FDA and comparable agencies in many foreign countries impose substantial limitations on the introduction of new pharmaceuticals through costly and time-consuming laboratory and clinical testing and other procedures. The process of obtaining FDA and other required regulatory approvals is lengthy, expensive and uncertain. Chrysalin and AZX100 are new drugs and subject to the most stringent level of FDA review.

     Even after we have invested substantial funds in the development of our three Chrysalin products and AZX100 and even if the results of our current clinical trials are favorable, there can be no guarantee that the FDA will grant approval of Chrysalin and/or AZX100 for the indicated uses or that it will do so in a timely manner.

     If we successfully bring one or more products to market, there is no assurance that we will be able to successfully manufacture or market the products or that potential customers will buy them if, for example, a competitive product has greater efficacy or is deemed more cost effective. In addition, the market in which we will sell any such products is dominated by a number of large corporations that have vastly greater resources than we have, which may impact our ability to successfully market our products or maintain any technological advantage we might develop. We also would be subject to changes in regulations governing the manufacture and marketing of our products, which could increase our costs, reduce any competitive advantage we may have and/or adversely affect our marketing effectiveness.

The pharmaceutical industry is subject to stringent regulation, and failure to obtain regulatory approval will prevent commercialization of our products.

     Our research, development, pre-clinical and clinical trial activities and the manufacture and marketing of any products that we may successfully develop are subject to an extensive regulatory approval process by the FDA and other regulatory agencies in the United States and abroad. The process of obtaining required regulatory approvals for drugs is lengthy, expensive and uncertain, and any such regulatory approvals may entail limitations on the indicated usage of a drug, which may reduce the drug’s market potential.

     In order to obtain FDA approval to commercialize any product candidate, an NDA must be submitted to the FDA demonstrating, among other things, that the product candidate is safe and effective for use in humans for each target indication. Our regulatory submissions may be delayed, or we may cancel plans to make submissions for product candidates for a number of reasons, including:

	•		negative or ambiguous pre-clinical or clinical trial results;
	•		changes in regulations or the adoption of new regulations;
	•		unexpected technological developments; and
	•		developments by our competitors that are more effective than our product candidates.

     Consequently, we cannot assure that we will make our submissions to the FDA in the timeframe that we have planned, or at all, or that our submissions will be approved by the FDA. Even if regulatory clearance is obtained, post-market evaluation of our products, if required, could result in restrictions on a product’s marketing or withdrawal of a product from the market as well as possible civil and criminal sanctions.

     Clinical trials are subject to oversight by institutional review boards and the FDA to ensure compliance with the FDA’s good clinical practice regulations, as well as other requirements for good clinical practices. We depend, in part, on third-party laboratories and medical institutions to conduct pre-clinical studies and clinical trials for our products and other third-party organizations, usually universities, to perform data collection and analysis, all of which must maintain both good laboratory and good clinical practices. If any such standards are not complied with in our clinical trials, the FDA may suspend or terminate such trial, which would severely delay our development and possibly end the development of a product candidate.

     We also currently and in the future will depend upon third party manufacturers of our products, which are and will be required to comply with the applicable FDA Good Manufacturing Practice regulations. We cannot be certain that our present or future manufacturers and suppliers will comply with these regulations. The failure to comply with these regulations may result in restrictions in the sale of, or withdrawal of the products from the market. Compliance by third parties with these standards and practices are outside of our direct control.

     In addition, we are subject to regulation under state and federal laws, including requirements regarding occupational safety, laboratory practices, environmental protection and hazardous substance control, and may be subject to other local, state, federal and foreign regulation. We cannot predict the impact of such regulations on us, although they could impose significant restrictions on our business and require us to incur additional expenses to comply.

If our competitors develop and market products that are more effective than ours, or obtain marketing approval before we do, our commercial opportunities will be reduced or eliminated.

     Competition in the pharmaceutical and biotechnology industries is intense and is expected to increase. Several biotechnology and pharmaceutical companies, as well as academic laboratories, universities and other research institutions, are involved in research and/or product development for various treatments for or involving fracture repair, diabetic ulcer healing, and smooth muscle relaxation. Many of our competitors have significantly greater research and development capabilities, experience in obtaining regulatory approvals and manufacturing, marketing, financial and managerial resources than we have.

     Our competitors may succeed in developing products that are more effective than the ones we have under development or that render our proposed products or technologies noncompetitive or obsolete. In addition, certain of such competitors may achieve product commercialization before we do. If any of our competitors develops a product that is more effective than one we are developing or plan to develop, or is able to obtain FDA approval for commercialization before we do, we may not be able to achieve significant market acceptance for certain products of ours, which would have a material adverse effect on our business.

     For a summary of the competitive conditions relating to indications in which we are considering for our AZX100 and ICARMs research and development activities, see the section in this prospectus titled “The Company — AZX100 — ICARMs™ — Competition” and the reports we file with the Securities and Exchange Commission and incorporate by reference into the registration statement of which this prospectus is a part. For a summary of the competitive conditions relating to Chrysalin-based indications, please see our Annual Report on Form 10-K for the fiscal year ended December 31, 2005, and other reports we file with the Securities and Exchange Commission and incorporate by reference into the registration statement of which this prospectus is a part.

Our product candidates may not gain market acceptance among physicians, patients and the medical community, including insurance companies and other third party payors. If our product candidates fail to achieve market acceptance, our ability to generate revenue will be limited.

Even if we obtain regulatory approval for our products, market acceptance will depend on our ability to demonstrate to physicians and patients the benefits of our products in terms of safety, efficacy, and convenience, ease of administration and cost effectiveness. In addition, we believe market acceptance depends on the effectiveness of our marketing strategy, the pricing of our products and the reimbursement policies of government and third-party payors. Physicians may not prescribe our products, and patients may determine, for any reason, that our product is not useful to them. Insurance companies and other third party payors may determine not to reimburse for the cost of the therapy. If any of our product candidates fails to achieve market acceptance, our ability to generate revenue will be limited.

Healthcare reform and restrictions on reimbursements may limit our financial returns.

     Our ability to successfully commercialize our products may depend in part on the extent to which government health administration authorities, private health insurers and other third party payors will reimburse consumers for the cost of these products. Third party payors are increasingly challenging both the need for, and the price of, novel therapeutic drugs and uncertainty exists as to the reimbursement status of newly approved therapeutics. Adequate third party reimbursement may not be available for our drug products to enable us to maintain price levels sufficient to realize an appropriate return on our investments in research and product development, which could restrict our ability to commercialize a particular drug candidate.

Risks Related to Our Common Stock

Our stock price is volatile and fluctuates due to a variety of factors.

     Our stock price has varied significantly in the past (from a high of $8.96 to a low of $2.22 from January 1, 2004 to March 28, 2006) and may vary in the future due to a number of factors, including:

	•		announcement of the results of, or delays in, preclinical and clinical studies;
	•		fluctuations in our operating results;
	•		developments in litigation to which we or a competitor is subject;
	•		announcements and timing of potential acquisitions, divestitures, capital raising activities and conversions of preferred stock;
	•		announcements of technological innovations or new products by us or our competitors;
	•		FDA and other regulatory actions;
	•		developments with respect to our or our competitors’ patents or proprietary rights;
	•		public concern as to the safety of products developed by us or others; and
	•		changes in stock market analyst recommendations regarding us, other drug development companies or the pharmaceutical industry generally.

In addition, the stock market has from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the market price of our stock.

Additional authorized shares of our common stock available for issuance may have dilutive and other material effects on our stockholders.

     We are authorized to issue 100,000,000 shares of common stock. As of March 28, 2006, there were 40,673,489 shares of common stock issued and outstanding. However, the total number of shares of our common stock issued and outstanding does not include shares reserved in anticipation of the exercise of options, warrants or additional investment rights. As of March 28, 2006 we had stock options outstanding to purchase approximately 2,713,096 shares of our common stock, the exercise price of which range between $2.43 per share to $17.38 per share, warrants outstanding to purchase 286,706 shares of our common stock with an exercise price of $6.39, and we have reserved shares of our common stock for issuance in connection with the potential exercise thereof. Additionally, at our Annual Stockholder Meeting on May 12, 2006, we are requesting that our stockholders approve the OrthoLogic 2005 Equity Incentive Plan, which provides an additional 2,000,000 shares of our common stock for incentive awards.

     As disclosed in the Registration Statement on Form S-3 we filed on April 13, 2006, on February 27, 2006 (the “Closing Date”), we closed the initial transactions relating to our Common Stock and Warrant Purchase Agreement (the “Purchase Agreement”) dated February 24, 2006 with PharmaBio Development Inc. (“PharmaBio”), an affiliate of Quintiles Transactional Corp. and Quintiles, Inc., which provides for the purchase of shares of our common stock in three tranches. On the Closing Date, PharmaBio purchased 359,279 shares of our common stock for a purchase price of $2,000,000 based on the average closing stock price for the 15-day period prior to that date. In addition, we also entered into a Class A Warrant Agreement with PharmaBio on the same date, whereby we issued PharmaBio a fully vested warrant to purchase 46,706 shares of our common stock at $6.39 a share. At our

election, PharmaBio will purchase an additional amount of our common stock for a purchase price of $1,500,000 on each of June 30, 2006 and September 29, 2006 with the number of shares to be determined by the 15-day average closing stock price prior to each such date. Each additional stock purchase will include the issuance of fully vested warrants, exercisable for a ten-year period from the date of issuance, for an amount of shares equal to 13% of the shares purchased on the date of issuance, with the exercise price set at 115% of the share price of each respective share purchase (each, an “Additional Class A Warrant,” and collectively, the “Additional Class A Warrants”). We are also parties to a Class B Warrant Agreement (the “Class B Warrant”), Class C Warrant Agreement (the “Class C Warrant”) and a Class D Warrant Agreement (the “Class D Warrant”) with PharmaBio to purchase in the aggregate up to 240,000 shares of our common stock at $6.39 a share (the Class B Warrant, Class C Warrant and Class D Warrant are collectively referred to in this prospectus as the “Milestone Warrants”). The Milestone Warrants, all dated as of February 24, 2006, will be exercisable for a ten-year period from that date, and will vest based on the achievement of certain milestones.

          To the extent such options or warrants are exercised or additional stock is issued, the holders of our common stock will experience further dilution. In addition, in the event that any future financing or consideration for a future acquisition should be in the form of, be convertible into or exchangeable for, equity securities, investors will experience additional dilution.

Certain provisions of our amended and restated certificate of incorporation and bylaws will make it difficult for stockholders to change the composition of our board of directors and may discourage takeover attempts that some of our stockholders may consider beneficial.

          Certain provisions of our amended and restated certificate of incorporation and bylaws may have the effect of delaying or preventing changes in control if our board of directors determines that such changes in control are not in the best interests of OrthoLogic Corp. and our stockholders. These provisions include, among other things, the following:

	•		a classified board of directors with three-year staggered terms;
	•		advance notice procedures for stockholder proposals to be considered at stockholders’ meetings;
	•		the ability of our board of directors to fill vacancies on the board;
	•		a prohibition against stockholders taking action by written consent; and
	•		super majority voting requirements for the stockholders to modify or amend our bylaws and specified provisions of our amended and restated certificate of incorporation.

          These provisions are not intended to prevent a takeover, but are intended to protect and maximize the value of our stockholders’ interests. While these provisions have the effect of encouraging persons seeking to acquire control of our company to negotiate with our board of directors, they could enable our board of directors to prevent a transaction that some, or a majority, of our stockholders might believe to be in their best interests and, in that case, may prevent or discourage attempts to remove and replace incumbent directors. In addition, we are subject to the provisions of Section 203 of the Delaware General Corporation Law, which prohibits business combinations with interested stockholders. Interested stockholders do not include stockholders whose acquisition of our securities is pre-approved by our board of directors under Section 203.

We may issue additional shares of preferred stock that have greater rights than our common stock and also have dilutive and anti-takeover effects.

          We are permitted by our amended and restated certificate of incorporation to issue up to 2,000,000 shares of preferred stock. We can issue shares of our preferred stock in one or more series and can set the terms of the preferred stock without seeking any further approval from our common stockholders or other security holders. Any preferred stock that we issue may rank ahead of our common stock in terms of dividend priority or liquidation rights and may have greater voting rights than our common stock.

          In connection with the Rights Agreement dated as of March 4, 1997 between us and the Bank of New York, as amended (the “Rights Agreement”), our board approved the designation of 500,000 shares of Series A Preferred Stock. The Rights Agreement and the exercise of rights to purchase Series A Preferred Stock pursuant to the terms thereof may delay, defer or prevent a change in control because the terms of any issued Series A Preferred Stock would potentially prohibit our consummation of certain extraordinary corporate transactions without the approval of the Board. In addition to the anti-takeover effects of the rights granted under the Rights Agreement, the issuance of preferred stock, generally, could have a dilutive effect on our stockholders.

We have not previously paid dividends on our common stock and we do not anticipate doing so in the foreseeable future.

          We have not in the past paid any dividends on our common stock and do not anticipate that we will pay any dividends on our common stock in the foreseeable future. Any future decision to pay a dividend on our common stock and the amount of any dividend paid, if permitted, will be made at the discretion of our board of directors.

Future sales or the potential for sale of a substantial number of shares of our common stock could cause the trading price of our common stock to decline and could impair our ability to raise capital through subsequent equity offerings.

          Sales of a substantial number of shares of our common stock in the public markets, or the perception that these sales may occur, could cause the market price of our stock to decline and could materially impair our ability to raise capital through the sale of additional equity securities. This prospectus covers the resale of shares that previously were restricted. As a result, the number of our securities eligible to be sold in the market will increase upon the effectiveness of this registration statement. If the selling security holders sell a significant amount of this common stock, or if there is a perception that such sales will be effected, the prices of those securities could drop.

          We caution that the foregoing list of important factors is not exhaustive and may not be up to date. Developments in any of these areas could cause our results to differ materially from results that have been or may be projected by us.

THE COMPANY

Overview of the Business

CHRYSALIN®

          OrthoLogic is a biotechnology company focused on the development and commercialization of the novel synthetic peptide Chrysalin® (TP508) in two lead indications, both of which represent areas of significant unmet medical need – fracture repair and diabetic foot ulcer healing. Chrysalin, or TP508, is a 23-amino acid synthetic peptide representing a receptor-binding domain of the human thrombin molecule, a naturally occurring agent responsible for blood clotting and initiating the natural healing cascade of cellular events responsible for tissue repair – both soft tissue and bone.

          On March 15, 2006, we reported results of our Phase 3 fracture repair human clinical trial. For the primary endpoint, immobilization removal, no statistically significant difference between placebo and a single injection of Chrysalin were achieved. Consistent with the Phase 1/2 human clinical trial results, a statistically significant difference for a secondary endpoint, radiographic evidence of radial cortical bridging, was achieved. However, no statistically significant difference was noted in the study’s other secondary endpoints. On March 15, 2006, we temporarily interrupted enrollment in our Phase 2b fracture repair dosing clinical trial to perform an interim analysis of the 273 patients enrolled up to that date. We plan to announce the results of the interim analysis and our future fracture repair indication plans by the 3^rd Quarter of 2006.

AZX100 — ICARMs™

          On February 23, 2006 we entered into an agreement to purchase certain assets and assume certain liabilities of AzERx, Inc. The transaction was completed (closed) on February 27, 2006. Under the terms of the transaction, OrthoLogic acquired an exclusive license for the core intellectual property relating to AZX100, and will continue to develop the new class of compounds in the field of smooth muscle relaxation called Intracellular Actin Relaxing Molecules, or ICARMs™, based on the unique technology developed by AzERx. The acquisition provides us with a new technology platform that diversifies the portfolio, and may provide more than one potential product. AzERx’s lead compound is AZX100, a 24-amino acid peptide. AZX100 is currently being investigated for medically important and commercially significant applications such as the treatment of vasospasm associated with subarachnoid hemorrhage (SAH), prevention of keloid scarring, and the treatment of asthma. Preclinical and human in vitro studies have shown that this novel compound has the ability to relax smooth muscle in multiple tissue types. We will continue pre-clinical activities on AZX100 in 2006.

          We continue to evaluate other biopharmaceutical compounds that can complement our research activity internally and broaden our potential pipeline for successful products.

Additional Information about OrthoLogic

          OrthoLogic Corp. was incorporated as a Delaware corporation in July 1987 as IatroMed, Inc. We changed our name to OrthoLogic Corp. in July 1991. Our executive offices are located at 1275 West Washington Street, Tempe, Arizona 85281, and our telephone number is (602) 286-5520.

          Our website address is www.orthologic.com. Our annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, as well as any amendments to those reports, are available free of charge through our website as soon as reasonably practical after we file or furnish them to the U.S. Securities and Exchange Commission. Once at our website, go to the “Investors” section to locate these filings.

          In March 2004, we adopted a code of conduct that applies to all of our employees and has particular sections that apply only to our principal executive officer and senior financial officers. We posted the text of our code of conduct on our website in the “Investors” section of our website under “Code of Conduct.” In addition, we will promptly disclose on our website (1) the nature of any amendment to our code of conduct that applies to our principal executive officer and senior financial officers, and (2) the nature of any waiver, including an implicit

          We completed patient enrollment in our pivotal Phase 3 human clinical trial evaluating the efficacy of Chrysalin in patients with unstable and/or displaced distal radius (wrist) fractures in May 2005. We enrolled a total of 503 study patients in 27 health centers throughout the United States. The primary efficacy endpoint in the trial is to measure how quickly wrist fractures in patients injected with Chrysalin heal, as measured by the removal of immobilization. Accelerated removal of immobilization allows patients to initiate hand therapy and regain full function of their wrists and hands sooner. The clinical trial’s secondary efficacy endpoints include radiographic analysis of healing, as well as clinical, functional, and patient outcome parameters. On March 15, 2006, we reported results of our Phase 3 fracture repair human clinical trial. For the primary endpoint, immobilization removal, no statistically significant difference between placebo and a single injection of Chrysalin were achieved. Consistent with the Phase 1/2 human clinical trial results, a statistically significant difference for a secondary endpoint, radiographic evidence of radial cortical bridging, were achieved. However, no statistically significant difference was noted in the study’s other secondary endpoints. To date, there have been no adverse events related to Chrysalin reported in this Phase 3 trial.

          We are also conducting a Phase 2b human clinical trial to establish the lower dose range of Chrysalin versus a placebo control, as well as to provide information to support our potential future fracture repair new drug application (“NDA”). Our enrollment goal was 500 patients in approximately 60 sites. On March 15, 2006, we temporarily interrupted enrollment in our Phase 2b fracture repair dosing clinical trial to perform an interim analysis of the 273 patients enrolled up to that date. We plan to announce the results of the interim analysis and our future fracture repair indication plans by the 3^rd Quarter of 2006.

          Dermal Wound Healing

          Our dermal wound healing studies are focused on healing diabetic foot ulcers, a common problem for diabetic patients. Diabetic patients suffer from open wound foot ulcers because diabetes related nerve damage causes the patient to lose sensation. Patients thus may not notice an injury to the foot and neglect the injury. This fact and the diminished blood flow to extremities caused by diabetes cause a diabetic patient’s wounds to heal more slowly or not at all.

          Current standard treatment for diabetic foot ulcer wounds focuses on sanitation of the wound and non-use of the foot (off loading) to allow for the body’s natural healing processes to occur. These treatments require high patient compliance and effectively heal only approximately 33% of these ulcers. Wounds that do not respond to treatment can sometimes result in amputation of the affected limb.

          We believe topical treatment of the wound with Chrysalin will promote new tissue growth necessary for healing of a diabetic foot ulcer. CBI conducted a multicenter Phase 1/2 double blind human trial with 60 patients, the results of which were presented at the Wound Healing Society in May of 2002. We found no drug related adverse events or patient sensitivity to Chrysalin in the trial and complete wound closure occurred in 70% of Chrysalin-treated ulcers relative to 33% in placebo controls, a statistically significant difference.

          Our pre-clinical studies and the initial Phase 1/2 human clinical trial evaluated Chrysalin in a saline formulation. We are currently evaluating various gel formulations of Chrysalin that will make Chrysalin easier for patients to use. We have developed a gel formulation for this indication and our plan is to test the gel formulation in human clinical trials for diabetic ulcer wound healing starting in the second half of fiscal 2006.

          Spine Fusion

          Spine fusion surgery is most commonly performed to treat degenerative disk disease, spinal instability and other disorders of the spine that are believed to be the cause of back and neck pain. The surgery involves the fusing of one or more vertebrae of the spine by placement of bone graft material around the targeted area of the spine during surgery. The body then heals the grafts over several months, which fuses the vertebrae together with newly formed bone so there is no longer movement between the vertebrae.

          The bone used for the graft in this procedure is taken from another bone in the patient, usually from the iliac crest (hip bone) and is called “autograft bone.” In some procedures the patients and physicians elect to use “allograft” bone which is bone processed from cadavers. Autograft bone is currently the primary type of bone graft

ended December 31, 2005, and other reports we file with the Securities and Exchange Commission and incorporate by reference into the registration statement of which this prospectus is a part.

          Subarachnoid Hemorrhage (SAH)

Approved

          The only current pharmacological treatment for SAH is the calcium channel antagonist Nimotop (nimodipine). Although Nimotop significantly improves the outcome of surviving patients through a neuroprotective effect, it has not been shown to alter the incidence or magnitude of vasospasm or to decrease mortality. Nimotop carries in the label a “black box” warning regarding i.v. or other parenteral administration.

In Development

          The other potential competing products currently under development for SAH are endothelin antagonists (endothelin has been implicated in SAH-induced vasospasm). Elevated plasma levels of endothelin-1 (ET-1) have been shown to occur in patients with SAH-induced vasospasm, although the timing of endothelin elevation has varied from as early as three days after SAH to 8 – 14 days after SAH. Such differences indicate endothelin may not induce vasospasm, but rather may play a role in vasospasm progression. Conflicting results have also been reported regarding the cerebrospinal fluid levels of ET-1. Taken together, these studies indicate that endothelin may contribute to SAH-induced vasospasm. Thus, clinical trials have been conducted for Acetelion’s endothelial antagonists, clazosentan (specific ET_A receptor antagonist) and bosentan (Tracleer®, dual ET_A and ET_B receptor antagonist). Although bosentan appears effective for pulmonary arterial hypertension, the trial for SAH was discontinued because of a lack of efficacy.

          Roche is developing a follow-up compound from bosentan, Ro 61-1790, to improve water solubility and ET_A potency and has demonstrated in vivo efficacy with a canine double hemorrhage model. In the double hemorrhage model two blood clots must be placed to cause vasospasm. While vasospasm can be demonstrated angiographically, it does not typically result in cerebral infarction. Thus, Ro 61-1790 must be tested in humans to determine whether its improvements will increase efficacy.

          The primary disadvantage of endothelin antagonists is that they act on a single vasoconstrictor, although additional mediators have been implicated in SAH. Therefore, targeting downstream vasorelaxing pathways with administration of AZX100 may be more effective. In addition, the ET receptor is internalized once it interacts with the ET peptide. Thus, this drug may only be effective as a prevention measure, not treatment.

          In addition, the recombinant haemostatic agent NovoSeven (activated factor VIIa) is currently registered for treatment of bleeding of hemophelia patients, but has also been shown to be effective against the intracerebral hemorrhage (ICH) in phase 2b clinical trials. NovoSeven accelerates the coagulation process at the site of ICH limiting hematoma.

Keloid Scarring

Approved

          There is no approved pharmacologic treatment for scarless healing. In the setting of keloid formation, the scars are often excised and treated with steroids with variable results.

In Development

          The potential competing products are recombinant transforming growth ß-3 (TGF- ß-3) and antiTGF- ß-1. Renovo is conducting phase 3 clinical trials in Europe on recombinant hTGF- ß-3 (Justiva). While preliminary efficacy has been shown in healing in healthy individuals, like other therapeutics, rhTGF- ß-3 addresses only part of the pathway that end in phosphorylation of our target molecule and results in scar inhibition. The potential of the AZX100 to completely inhibit the entire scarring pathways suggests that AZX100 may be more effective than rhTGF- ß-3 at scarless healing, Renovo has also begun clinical trials on antihTGF- ß-1, which like rhTGF- ß-3 also

blocks part of the signaling cascade resulting in scar formation. AZX100 may be more effective than antihTGF- ß-1 through more complete inhibition of the scarring cascade.

          While many other companies are investigating therapeutics for wound healing, these therapeutics will be synergistic with and not competitive with AZX100 as they are targeting more rapid healing and not scar inhibition.

Asthma

          Asthma ranks as the third highest reason for preventable hospitalizations in the U.S. with 470,000 hospitalizations and more than 5,000 deaths each year (American Academy of Allergy Asthma and Immunology Report). Acute asthma accounts for an estimated two-million emergency department visits annually. There are many competitors with asthma products approved or in development. AZX100 has been shown to relax airway smooth muscle and may be developed for the treatment of asthmatic attacks. Specific markets include severe acute asthma and asthma that is refractory to current therapies. Severe asthma has been defined as asthma that is refractory to current therapeutic approaches in clinical use (anti-inflammatory agents and bronchodilators). The current approach is to use ß-adrenergic agonists, which activate the cAMP/PKA pathway. AZX100 is a mimetic of the molecule downstream of this pathway and hence may be more sensitive and specific for the treatment of severe asthma. In addition, patients with severe asthma present to the emergency room for treatment, hence efficacy can be closely monitored and outcomes will be apparent in a short time frame after treatment. Recent data has demonstrated that one out of every six asthmatics has a mutation in the ß-adrenergic receptor. These patients do not respond to ß-adrenergic agonists and in fact do worse when treated with ß-adrenergic agonists. This patient population would be potentially treated with the AZX100 compound in that it acts downstream of the receptors.

MATERIAL CHANGES

          On April 5, 2006, James M. Pusey, MD resigned as our President and Chief Executive Officer and as a Class I director of the company. John M. Holliman, III, a director of OrthoLogic since September 1987 and Chairman of the Board of Directors since August 1997, assumed the title of Executive Chairman on that date. In that position, Mr. Holliman will serve as our principal executive officer and will lead our business and corporate strategic activities. Randolph C. Steer, MD, Ph.D. was named our President on April 5, 2006, and will be responsible for directing our strategy and operations in all clinical development and regulatory areas.

          On March 15, 2006, we reported results of our Phase 3 fracture repair human clinical trial. For the primary endpoint, immobilization removal, no statistically significant difference between placebo and a single injection of Chrysalin were achieved. Consistent with the Phase 1/2 human clinical trial results, a statistically significant difference for a secondary endpoint, radiographic evidence of radial cortical bridging, was achieved. However, no statistically significant difference was noted in the study’s other secondary endpoints. On March 15, 2006, we temporarily interrupted enrollment in our Phase 2b fracture repair dosing clinical trial to perform an interim analysis of the 273 patients enrolled up to that date. We plan to announce the results of the interim analysis and our future fracture repair indication plans by the 3^rd Quarter of 2006.

          As disclosed in the Registration Statement on Form S-3 we filed on April 13, 2006, on February 27, 2006 (the “Closing Date”), we closed the initial transactions relating to our Common Stock and Warrant Purchase Agreement (the “Purchase Agreement”) dated February 24, 2006 with PharmaBio Development Inc. (“PharmaBio”), an affiliate of Quintiles Transactional Corp. and Quintiles, Inc., which provides for the purchase of shares of our common stock in three tranches. On the Closing Date, PharmaBio purchased 359,279 shares of our common stock for a purchase price of $2,000,000 based on the average closing stock price for the 15-day period prior to that date. In addition, we also entered into a Class A Warrant Agreement with PharmaBio on the same date, whereby we issued PharmaBio a fully vested warrant to purchase 46,706 shares of our common stock at $6.39 a share. At our election, PharmaBio will purchase an additional amount of our common stock for a purchase price of $1,500,000 on

20

each of June 30, 2006 and September 29, 2006 with the number of shares to be determined by the 15-day average closing stock price prior to each such date. Each additional stock purchase will include the issuance of fully vested warrants, exercisable for a ten-year period from the date of issuance, for an amount of shares equal to 13% of the shares purchased on the date of issuance, with the exercise price set at 115% of the share price of each respective share purchase (each, an “Additional Class A Warrant,” and collectively, the “Additional Class A Warrants”). We are also parties to a Class B Warrant Agreement (the “Class B Warrant”), Class C Warrant Agreement (the “Class C Warrant”) and a Class D Warrant Agreement (the “Class D Warrant”) with PharmaBio to purchase in the aggregate up to 240,000 shares of our common stock at $6.39 a share (the Class B Warrant, Class C Warrant and Class D Warrant are collectively referred to in this prospectus as the “Milestone Warrants”). The Milestone Warrants, all dated as of February 24, 2006, will be exercisable for a ten-year period from that date, and will vest based on the achievement of certain milestones.

          In connection with our entry into the Purchase Agreement, we also entered into a Master Services Agreement with Quintiles, Inc. (“Quintiles”) whereby Quintiles will become our exclusive clinical research organization service provider for our Chrysalin Product Platform and will provide certain other technical assistance. As consideration for entry into the Master Services Agreement, we have granted Quintiles the right of first negotiation to promote Chrysalin if it is approved by the U.S. Food and Drug Administration.

          On February 23, 2006, we entered into an agreement to purchase certain assets and assume certain liabilities of AzERx, Inc. The transaction closed on February 27, 2006. Under the terms of the agreement, we acquired an exclusive license for the core intellectual property relating to AzERx’s lead compound, AZX100, a 24-amino acid peptide. AZX100 is currently being investigated for several applications, including the treatment of vasospasm associated with subarachnoid hemorrhage, prevention of keloid scarring, and treatment of asthma. We will continue to develop the new class of compounds in the field of smooth muscle relaxation called Intracellular Actin Relaxing Molecules, or ICARMs™, based on the AZX100 technology.

USE OF PROCEEDS

          The shares of our common stock offered by this prospectus will be sold by the selling security holders, and the selling security holders will receive all of the proceeds from the sale of such shares. We will not receive any proceeds from sales of the shares offered by this prospectus.

SELLING SECURITY HOLDERS

          On February 27, 2006 (the “Closing Date”), pursuant to an Asset Purchase Agreement and Plan of Reorganization (the “Purchase Agreement”), we acquired certain assets and assumed certain liabilities of AzERx, Inc. (“AzERx”) for $390,000 in cash and the issuance of 1,325,000 shares of our common stock (the “AzERx Transaction”). In connection with the AzERx Transaction, on the Closing Date, we also issued 30,000 shares of our common stock to Arizona Science and Technology Enterprises, LLC (“AzTE”), the licensor of AzERx’s core technology patents, for certain modifications of the license. In accordance with the Purchase Agreement, of the 1,325,000 shares originally issued to AzERx, 132,500 shares were deposited in an escrow account for twelve months with Wells Fargo Bank, N.A., as escrow agent, to secure AzERx’s potential indemnification obligations under the Purchase Agreement (the “Escrow Shares”). As part of a plan of reorganization, AzERx distributed to its stockholders 1,192,500 shares, consisting of the 1,325,000 shares of our common stock it received from the sale of its assets to us, less the Escrow Shares. The 1,192,500 shared issued to AzERx and subsequently distributed to its stockholders, the 132,500 Escrow Shares, and the 30,000 additional shares issued to AzTE are being registered for resale under this prospectus.

          The selling security holders will not have the right to sell the Escrow Shares until they are released from the escrow account in accordance with the terms of our escrow agreement with AzERx and the escrow agent (the “AzERx Escrow Agreement”). In the event we are entitled to indemnification under the Purchase Agreement, the indemnification will be satisfied with the Escrow Shares. In that event, the selling security holders will no longer beneficially own the shares of common stock used to satisfy the indemnification obligations and such shares may not be offered pursuant to this prospectus. We will file a prospectus supplement or file any required amendment to the registration statement of which this prospectus is a part in the event any shares of common stock held in escrow

21

pursuant to the AzERx Escrow Agreement are used to satisfy indemnification obligations under the Purchase Agreement.

          The registration statement including this prospectus is filed pursuant to our requirement under the Purchase Agreement to register for resale the shares paid to AzERx. The terms of our obligations, which also include our agreement to register for resale the 30,000 shares we issued to AzTE as part of the AzERx Transaction, are evidenced in a registration rights agreement, which is filed as Exhibit 10.2 to the registration statement of which this prospectus is a part. This prospectus also covers any additional shares of our common stock that become issuable in connection with the shares being registered by reason of any stock splits, stock dividends or similar transactions.

          The following table provides certain information as of the date hereof regarding the beneficial ownership of our common stock by the selling security holders prior to and after the issuance of our common stock to the selling security holders in connection with the AzERx Transaction. Beneficial ownership is determined under the rules of the Securities and Exchange Commission and generally includes voting or investment power with respect to securities. To our knowledge, except under applicable community property laws, or as otherwise indicated, each person named in the table has sole voting and investment control with regard to all shares beneficially owned by such person. To our knowledge, except as otherwise indicated in footnotes to the table, and other than as a result of each selling security holder’s beneficial ownership of our common stock as a result of the AzERx Transaction, we are not aware of any material relationship between us and any of the selling security holders within the past three years, and none of the selling security holders currently has or had a position or office with us within the past three years.

          Our registration of shares does not necessarily mean that the selling security holders will sell all or any of these securities. We have assumed for purposes of the table below that the selling security holders will sell all of the shares offered for sale. The selling security holders may have sold, transferred or otherwise disposed of all or a portion of their shares, or acquired additional shares, since the date on which they provided information regarding their securities.

PLAN OF DISTRIBUTION

          We will not receive any of the proceeds from the resale by the selling security holders of any of the securities covered by this prospectus. The aggregate proceeds to the selling security holders from the sale of our common stock will be the purchase price of the common stock less any discounts and commissions. The selling security holders reserve the right to accept and, together with their agents, to reject, any proposed purchase of common stock to be made directly or through agents. As used in this prospectus, to the extent applicable, “selling security holders” includes holders of shares of our common stock received from the selling security holders after the date of this prospectus and who received such shares by gift, partnership distribution or by other non-sale related transfer by the selling security holders, including transfers to an immediate family member of such stockholder, by will or through operation of the laws of descent and distribution, and their respective administrators, guardians, receivers, executors or other persons acting in a similar capacity.

          The common stock may be sold from time to time to purchasers:

	•		directly by the selling security holders and their successors, which includes their transferees, pledgees or donees or their successors; or
	•		through underwriters, broker-dealers or agents who may receive compensation in the form of discounts, concessions or commissions from the selling security holders or the purchasers of the common stock. These discounts, concessions or commissions may be in excess of those customary in the types of transactions involved.

          The shares held by the selling security holders listed on the selling security holder table above that are currently held in escrow pursuant to the AzERx Escrow Agreement may not be sold by the selling security holders until February 28, 2007 when they are released from escrow, to the extent any such shares have not been used to satisfy indemnification obligations under the Purchase Agreement.

          Pursuant to lock-up agreements with Alyssa Panitch, Colleen Brophy, Elizabeth Furnish, Terry Winters, Dennis Goldberg, Randolph Steer and Valley Ventures III, the resale of the shares of our common stock received and beneficially owned by such selling security holders and permitted transferees in connection with the AzERx Transaction is limited to no more than 10% of such shares in any calendar month until February 27, 2008.

          The selling security holders and any underwriters, broker-dealers or agents who participate in the distribution of the common stock may be deemed to be “underwriters” within the meaning of the Securities Act of 1933, as amended. As a result, any profits on the sale of the common stock by the selling security holders and any discounts, commissions or concessions received by any such broker-dealers or agents may be deemed to be underwriting discounts, and “underwriters” within the meaning of the Securities Act will be subject to prospectus delivery requirements of the Securities Act. If any of the selling security holders are deemed to be underwriters, such selling security holders may be subject to certain statutory liabilities, including, without limitation, liabilities under Sections 11, 12 and 17 of the Securities Act and Rule 10b-5 under the Securities Exchange Act of 1934, as amended. If the common stock is sold through underwriters, broker-dealers or agents, the selling security holders will be responsible for underwriting discounts or commissions or agent’s commissions.

          The common stock may be sold in one or more transactions at:

	•		fixed prices;
	•		prevailing market prices at the time of sale;
	•		prices related to such prevailing market prices;
	•		varying prices determined at the time of sale; or
	•		negotiated prices.

          These sales may be effected in transactions:

	•		on any national securities exchange or quotation service on which the common stock may be listed or quoted at the time of the sale;
	•		in the over-the-counter market;
	•		otherwise than on such exchanges or services or in the over-the-counter market;
	•		through the writing and exercise of options, whether such options are listed on an options exchange or otherwise; or
	•		through the settlement of short sales.

          These transactions may include block transactions or crosses. Crosses are transactions in which the same broker acts as an agent on both sides of the trade.

          In connection with the sales of the common stock or otherwise, the selling security holders may enter into hedging transactions with broker-dealers or other financial institutions. These broker-dealers or other financial institutions may in turn engage in short sales of the common stock in the course of hedging their positions. The selling security holders may also sell the common stock short and deliver common stock to close out short positions, or loan or pledge common stock to broker-dealers that in turn may sell the common stock.

          Broker-dealers engaged by the selling security holders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling security holders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling security holders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved.

          The selling security holders may from time to time pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling security holders to include the pledgee, transferee or other successors in interest as selling security holders under this prospectus.

          At the time a particular offering is made, if required, a prospectus supplement will be distributed, which will set forth the names of the selling security holders, the aggregate amount and type of securities being offered, the price at which the securities are being sold and other material terms of the offering, including the name or names of any underwriters, broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling security holders and any discounts, commissions or concessions allowed or reallowed to broker-dealers.

          We cannot be certain that the selling security holders will sell any or all of the common stock pursuant to this prospectus. Further, we cannot assure you that the selling security holders will not transfer, devise or gift the common stock by other means not described in this prospectus, including sales under Rule 144 of the Securities Act. The common stock may be sold in some states only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification is available and complied with.

          The selling security holders and any other person participating in the sale of the common stock will be subject to the Exchange Act. The Exchange Act rules include, without limitation, Regulation M, which may limit the timing of purchases and sales of any of the common stock by the selling security holders and any other such persons. In addition, Regulation M may restrict the ability of any person engaged in the distribution of the common stock and the ability of any person or entity to engage in market-making activities with respect to the common stock.

          We have agreed to pay substantially all expenses incidental to the registration, offering and sale of the common stock to the public, other than commissions, fees and discounts of underwriters, brokers, dealers and agents. We have also agreed to indemnify the selling security holders and related persons against specified liabilities, including liabilities under the Securities Act.

          Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons, we have been informed that in the opinion of the Securities and Exchange Commission, this indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

DESCRIPTION OF CAPITAL STOCK

          Our restated certificate of incorporation provides that we have the authority to issue 100 million shares of $0.0005 par value common stock and 2 million shares of $0.0005 par value preferred stock.

          The following is a summary of the material provisions of our common stock and preferred stock. This summary does not purport to be exhaustive and is qualified in its entirety by reference to applicable Delaware law and our restated certificate of incorporation and bylaws.

Common Stock

          The holders of common stock are entitled to one vote per share on all matters to be voted upon by the stockholders. Stockholders are not entitled to cumulate their votes for the election of directors. Subject to preferences that may be applicable to any outstanding shares of preferred stock, the holders of common stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by the board of directors out of funds legally available for that purpose. In the event of our liquidation, dissolution or winding up, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. The common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of common stock are fully paid and nonassessable, and the shares of common stock to be issued upon completion of this offering will be fully paid and nonassessable.

          The transfer agent for our common stock is Bank of New York.

Preferred Stock

          Under our restated certificate of incorporation, our board of directors has the authority, without further action by our stockholders, to issue up to 2 million shares of preferred stock in one or more series and to fix the variations in the powers, preferences, rights, qualifications, limitations or restrictions of the preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights of our common stock. Our board of directors, without stockholder approval, can issue preferred stock with voting, conversion or other rights that could adversely affect the voting power and other rights of the holders of our common stock. As a result, preferred stock could be issued quickly with terms that will delay or prevent a change of control or make removal of management more difficult. In addition, the issuance of preferred stock may have the effect of decreasing the market price of our common stock and may adversely affect the voting and other rights of our common stock. At present, there are no shares of preferred stock outstanding and we have no current plans to issue any shares of preferred stock.

Preferred Stock Purchase Rights

          We have entered into a Rights Agreement, dated as of March 4, 1997, as amended, with Bank of New York, pursuant to which each outstanding share of our common stock has attached one preferred stock purchase right. Each share of our common stock subsequently issued prior to the expiration of the Rights Agreement will likewise have attached one right. Under specified circumstances involving a merger, an acquisition of 15% or more of our outstanding common stock, a tender offer or exchange offer resulting in ownership of 20% or more of our common stock by an acquiring person or a sale of 50% or more of our assets or earning power, the rights will entitle the holder thereof to purchase 1/100 of a share of our Series A preferred stock for a purchase price of $25.00 (subject to adjustment), and to receive, upon exercise, common shares having a value equal to two times the exercise price of the right. In this prospectus, unless the context requires otherwise, all references to our common stock include the accompanying rights.

          Currently, the rights are not exercisable and trade with our common stock.

Delaware Law

          We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, this statute prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date that the person became an interested stockholder unless (with certain exceptions) the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the stockholder. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns (or within three years prior, did own) 15% or more of the corporation’s voting stock.

Certain Anti-Takeover Provisions

          Stockholders’ rights and related matters are governed by Delaware corporate law, our restated certificate of incorporation (the “Restated Certificate”) and our bylaws. Certain provisions of the Restated Certificate and bylaws which are summarized below may discourage or have the effect of delaying or deferring potential changes in control of OrthoLogic Corp. Our board of directors believes that these provisions are in the best interests of stockholders because they will encourage a potential acquirer to negotiate with the board of directors, which will be able to consider the interests of all stockholders in a change-in-control situation. However, the cumulative effect of these terms may be to make it more difficult to acquire and exercise control of OrthoLogic Corp. and to make changes in our management.

          The Restated Certificate provides for the approval of the holders of two-thirds of our outstanding voting stock for a merger or a consolidation with, or a sale by us of all or substantially all of our assets to, any person, firm or corporation, or any group thereof, which owns, directly or indirectly, 5% or more of any class of our voting securities (an “Interested Person”). In addition, two-thirds approval is required with respect to other transactions

involving any such Interested Person, including among other things, purchase by us or any of our subsidiaries of all or substantially all of the assets or stock of an Interested Person and any other transaction with an Interested Person which requires stockholder approval under Delaware law. The two-thirds voting requirement is not applicable to any transaction approved by our board of directors if a majority of the members of the board of directors voting to approve such transaction were elected prior to the date on which the other party became an Interested Person or certain other conditions are met (the “Continuing Directors”).

     The Restated Certificate provides that each director will serve for a three-year term and that approximately one-third of the directors are to be elected annually. Candidates for directors shall be nominated only by the board of directors or by a stockholder who gives us written notice no later than 20 days before the annual meeting or, in the case of a special meeting, the close of business on the 15^th day following the date on which notice of such special meeting is first given to the stockholders. We may have three to nine directors as determined from time to time by our Board, which currently consists of six members. Between stockholder meetings, our Board may appoint new directors to fill vacancies or newly created directorships. The Restated Certificate does not provide for cumulative voting at stockholder meetings for the election of directors. Stockholders controlling at least 50% of the outstanding common stock can elect the entire board of directors, while stockholders controlling 49% of the outstanding common stock may not be able to elect any directors. A director may be removed from office only for cause and only by the affirmative vote of a majority of the combined voting power of the then outstanding shares of capital stock entitled to vote generally in the election of directors.

     The Restated Certificate further provides that stockholder action must be taken at a meeting of stockholders and may not be effected by any consent in writing. Special meetings of stockholders may be called only by the President, a majority of the board of directors or the holders of at least 35% of the outstanding shares of capital stock entitled to vote.

     The Restated Certificate provides further that the foregoing provisions of the Restated Certificate and bylaws may be amended or repealed only with the affirmative vote of at least two-thirds of the shares entitled to vote, unless the amendment is recommended for stockholder approval by a majority of the Continuing Directors. These provisions exceed the usual majority vote requirement of Delaware law and are intended to prevent the holders of less than two-thirds of the voting power from circumventing the foregoing terms by amending the Restated Certificate or bylaws. These provisions, however, enable the holders of more than one-third of the voting power to prevent amendments to the foregoing anti-takeover provisions of the Restated Certificate or bylaws even if they were favored by the holders of a majority of the voting power.

     The effect of such provisions of our Restated Certificate and bylaws may be to make more difficult the accomplishment of a merger or other takeover or change in control of OrthoLogic Corp. To the extent that these provisions have this effect, removal of our incumbent board of directors and management may be rendered more difficult. Furthermore, these provisions may make it more difficult for stockholders to participate in a tender or exchange offer for common stock and in so doing may diminish the market value of the common stock.

Limitations on Personal Liability of Directors

     Delaware law authorizes a Delaware corporation to eliminate or limit the personal liability of a director to the corporation and its stockholders for monetary damages for breach of certain fiduciary duties as a director. We believe that such a provision is beneficial in attracting and retaining qualified directors, and accordingly the Restated Certificate includes a provision eliminating liability for monetary damages for any breach of fiduciary duty as a director, except: (1) for any breach of the duty of loyalty to OrthoLogic Corp. or our stockholders; (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (3) for any transaction from which the director derived an improper personal benefit; or (4) for unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law. Thus, pursuant to Delaware law, our directors are not insulated from liability for breach of their duty of loyalty (requiring that, in making a business decision, directors act in good faith and in the honest belief that the action was taken in the best interest of the corporation). The foregoing provisions of the Restated Certificate may reduce the likelihood of derivative litigation against directors and may discourage or deter stockholders or management from bringing a lawsuit against directors for breaches of the fiduciary duties, even though an action, if successful, might otherwise have benefited us and our stockholders. Further, we have entered into indemnity agreements with all of

our directors and officers for the indemnification of and advancing of expenses to such persons to the fullest extent permitted by law. We have also obtained insurance for the benefit of our officers and directors insuring such persons against certain liabilities, including liabilities under the securities laws.
