PROSPECTUS 7,486,907 SHARES COMMON STOCK (NO PAR VALUE PER SHARE) CAL DIVE INTERNATIONAL, INC. 400 N. SAM HOUSTON PARKWAY E., SUITE 400 HOUSTON, TEXAS 77060 (281) 618-0400 This prospectus covers the potential resale of up to 7,486,907 shares of Common Stock of Cal Dive International, Inc., some or all of which could potentially be issued to Fletcher International, Ltd.

ABOUT CAL DIVE INTERNATIONAL, INC. We are an energy services company specializing in subsea construction and well operations as well as providing oil and gas companies with alternatives to the traditional approaches of equity sharing in offshore properties. We operate primarily in the Gulf of Mexico, or Gulf, and recently in the North Sea with services that cover the lifecycle of an offshore oil and gas field. We believe we have a longstanding reputation for innovation in our subsea construction techniques, equipment design and methods of partnering with customers. Our diversified fleet of 23 vessels and 21 remotely operated vehicles (ROVs) and trencher systems performs services that support drilling, well completion, intervention, construction and decommissioning projects involving pipelines, production platforms, risers and subsea production systems. We also have acquired significant interests in oil and gas properties and related production facilities as part of our Production Partnering business. Our customers include major and independent oil and gas producers, pipeline transmission companies and offshore engineering and construction firms. RISK FACTORS There are various risks, described below, any one of which may materially impact your investment in our company or may in the future, and, in some cases, already do, materially affect us and our business, financial condition, or results of operations and could result in a partial or complete loss of your investment. You should consider carefully these factors with respect to your investment in our Common Stock. This section includes or refers to certain forward-looking statements; you should read the explanation of the qualifications and limitations on such forward-looking statements beginning on page 6. OUR BUSINESS IS ADVERSELY AFFECTED BY LOW OIL AND GAS PRICES AND BY THE CYCLICALITY OF THE OIL AND GAS INDUSTRY. Our business is substantially dependent upon the condition of the oil and gas industry and, in particular, the willingness of oil and gas companies to make capital expenditures for offshore exploration, drilling and production operations. The level of capital expenditures generally depends on the prevailing view of future oil and gas prices, which are influenced by numerous factors affecting the supply and demand for oil and gas, including, but not limited to: - Worldwide economic activity, - Economic and political conditions in the Middle East and other oil-producing regions, - Coordination by the Organization of Petroleum Exporting Countries (OPEC), - The cost of exploring for and producing oil and gas, - The sale and expiration dates of offshore leases in the United States and overseas, - The discovery rate of new oil and gas reserves in offshore areas, - Technological advances, - Interest rates and the cost of capital, - Environmental regulations, and - Tax policies. The level of offshore construction activity did not increase despite higher commodity prices in 2002. We cannot assure you that activity levels will increase anytime soon. A sustained period of low drilling and production activity or the return of lower commodity prices would likely have a material adverse effect on our financial position and results of operations. 3

THE OPERATION OF MARINE VESSELS IS RISKY, AND WE DO NOT HAVE INSURANCE COVERAGE FOR ALL RISKS. Marine construction involves a high degree of operational risk. Hazards, such as vessels sinking, grounding, colliding and sustaining damage from severe weather conditions, are inherent in marine operations. These hazards can cause personal injury or loss of life, severe damage to and destruction of property and equipment, pollution or environmental damage and suspension of operations. Damage arising from such occurrences may result in lawsuits asserting large claims. We maintain such insurance protection as we deem prudent, including Jones Act employee coverage, which is the maritime equivalent of workers' compensation, and hull insurance on our vessels. We cannot assure you that any such insurance will be sufficient or effective under all circumstances or against all hazards to which we may be subject. A successful claim for which we are not fully insured could have a material adverse effect on us. Moreover, we cannot assure you that we will be able to maintain adequate insurance in the future at rates that we consider reasonable. As a result of market conditions, premiums and deductibles for certain of our insurance policies have increased substantially, and could escalate further. In some instances, certain insurance could become unavailable or available only for reduced amounts of coverage. For example, insurance carriers are now requiring broad exclusions for losses due to war risk and terrorist acts. As construction activity expands into deeper water in the Gulf, a greater percentage of our revenues may be from Deepwater construction projects that are larger and more complex, and thus riskier, than shallow water projects. As a result, our revenues and profits are increasingly dependent on our larger vessels. The current insurance on our vessels, in some cases, is in amounts approximating book value, which is less than replacement value. In the event of property loss due to a catastrophic marine disaster, mechanical failure or collision, insurance may not cover a substantial loss of revenues, increased costs and other liabilities, and could have a material adverse effect on our operating performance if we were to lose any of our large vessels. OUR CONTRACTING BUSINESS DECLINES IN WINTER, AND BAD WEATHER IN THE GULF OR NORTH SEA CAN ADVERSELY AFFECT OUR OPERATIONS. Marine operations conducted in the Gulf and North Sea are seasonal and depend, in part, on weather conditions. Historically, we have enjoyed our highest vessel utilization rates during the summer and fall when weather conditions are favorable for offshore exploration, development and construction activities. We typically have experienced our lowest utilization rates in the first quarter. As is common in the industry, we typically bear the risk of delays caused by some but not all adverse weather conditions. Accordingly, our results in any one quarter are not necessarily indicative of annual results or continuing trends. IF WE BID TOO LOW ON A TURNKEY CONTRACT, WE SUFFER CONSEQUENCES. A majority of our projects are performed on a qualified turnkey basis where described work is delivered for a fixed price and extra work, which is subject to customer approval, is billed separately. The revenue, cost and gross profit realized on a turnkey contract can vary from the estimated amount because of changes in offshore job conditions, variations in labor and equipment productivity from the original estimates, and the performance of others such as alliance partners. These variations and risks inherent in the marine construction industry may result in our experiencing reduced profitability or losses on projects. ESTIMATES OF OUR OIL AND GAS RESERVES, FUTURE CASH FLOWS AND ABANDONMENT COSTS MAY BE SIGNIFICANTLY INCORRECT. Our proved reserves at December 31, 2002, included the reserves assigned to our ownership position in the Gunnison project, a Deepwater Gulf of Mexico oil and gas field operated by Kerr-McGee Corporation. These reserves constitute 47% of our total proved reserves as of December 31, 2002. The reserves assigned to Gunnison were not generated by our reservoir engineers, as we do not own the seismic data for the three fields that comprise Gunnison. Instead, they were determined based on information provided by the operator, Kerr-McGee Oil & Gas Corporation. These reserve estimates were reviewed by our engineers, including an assessment of the operator's assumptions and their engineering, geologic and evaluation principles and techniques. This prospectus also contains estimates of our other proved oil and gas reserves and the estimated future net cash flows therefrom based upon reports for the years ended December 31, 2000, 2001 and 2002, 4

reviewed by Miller and Lents, Ltd., independent petroleum engineers. These reports rely upon various assumptions, including assumptions required by the Securities and Exchange Commission, as to oil and gas prices, drilling and operating expenses, capital expenditures, abandonment costs, taxes and availability of funds. The process of estimating oil and gas reserves is complex, requiring significant decisions and assumptions in the evaluation of available geological, geophysical, engineering and economic data for each reservoir. As a result, these estimates are inherently imprecise. Actual future production, cash flows, development expenditures, operating and abandonment expenses and quantities of recoverable oil and gas reserves may vary substantially from those estimated in these reports. Any significant variance in these assumptions could materially affect the estimated quantity and value of our proved reserves. You should not assume that the present value of future net cash flows from our proved reserves referred to in this prospectus is the current market value of our estimated oil and gas reserves. In accordance with Securities and Exchange Commission requirements, we base the estimated discounted future net cash flows from our proved reserves on prices and costs on the date of the estimate. Actual future prices and costs may differ materially from those used in the net present value estimate. In addition, if costs of abandonment are materially greater than our estimates, they could have an adverse effect on earnings. THE GUNNISON PROJECT MAY NOT RESULT IN THE EXPECTED CASH FLOWS OR SUBSEA ASSET UTILIZATION WE ANTICIPATE AND COULD INVOLVE SIGNIFICANT FUTURE CAPITAL OUTLAYS. The Gunnison project is subject to a number of assumptions and uncertainties, including estimates of the capital outlays necessary to develop the prospect and the cash flows that we may ultimately derive. We cannot assure you that we will be able to fund all required capital outlays or that these outlays will be profitable. Moreover, although we have contracts for subsea construction work, the extent of utilization of our subsea assets for such work has not been fully determined. We have a $35.0 million loan facility to provide for the financing of part of our portion of the construction costs of the spar, of which we had drawn down $31.9 million as of March 31, 2003. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources" in our Form 10-K/A listed under "Incorporation of Documents by Reference." EXPECTED CASH FLOWS FROM THE Q4000, INTREPID AND SEAWELL, AS WELL AS CANYON, MAY NOT BE IMMEDIATE OR AS HIGH AS EXPECTED. The Q4000, Intrepid and the Seawell are vessels that were placed into service during 2002. In addition, during 2002 we acquired Canyon Offshore, Inc., a supplier of ROVs to the offshore construction and telecommunications industry. We will not receive any material increase in revenue or cash flow from their operation until there is significant utilization of these vessels and Canyon's services. We cannot assure you that customer demand for these vessels and Canyon's services will be as high as currently anticipated and, as a result, our future cash flows may be adversely affected. New vessels from third parties may also enter the market in the coming years and compete with the Q4000, Intrepid and the Seawell for contracts. OUR OIL AND GAS OPERATIONS INVOLVE SIGNIFICANT RISKS, AND WE DO NOT HAVE INSURANCE COVERAGE FOR ALL RISKS. Our oil and gas operations are subject to risks incident to the operation of oil and gas wells, including, but not limited to, uncontrollable flows of oil, gas, brine or well fluids into the environment, blowouts, cratering, mechanical difficulties, fires, explosions, pollution and other risks, any of which could result in substantial losses to us. We maintain insurance against some, but not all, of the risks described above. WE MAY NOT BE ABLE TO COMPETE SUCCESSFULLY AGAINST CURRENT AND FUTURE COMPETITORS. The business in which we operate is highly competitive. Several of our competitors are substantially larger and have greater financial and other resources than we have. If other companies relocate or acquire vessels for operations in the Gulf or the North Sea, levels of competition may increase and our business could be adversely affected. 5

THE LOSS OF THE SERVICES OF ONE OR MORE OF OUR KEY EMPLOYEES, OR OUR FAILURE TO ATTRACT AND RETAIN OTHER HIGHLY QUALIFIED PERSONNEL IN THE FUTURE, COULD DISRUPT OUR OPERATIONS AND ADVERSELY AFFECT OUR FINANCIAL RESULTS. Our industry has lost a significant number of experienced subsea people over the years due to, among other reasons, the volatility in commodity prices. Our continued success depends on the active participation of our key employees. The loss of our key people could adversely affect our operations. We believe that our success and continued growth are also dependent upon our ability to attract and retain skilled personnel. We believe that our wage rates are competitive; however, unionization or a significant increase in the wages paid by other employers could result in a reduction in our workforce, increases in the wage rates we pay, or both. If either of these events occurs for any significant period of time, our revenues and profitability could be diminished and our growth potential could be impaired. IF WE FAIL TO EFFECTIVELY MANAGE OUR GROWTH, OUR RESULTS OF OPERATIONS COULD BE HARMED. We have a history of growing through acquisitions of large assets and acquisitions of companies. We must plan and manage our acquisitions effectively to achieve revenue growth and maintain profitability in our evolving market. If we fail to effectively manage current and future acquisitions, our results of operations could be adversely affected. Our growth has placed, and is expected to continue to place, significant demands on our personnel, management and other resources. We must continue to improve our operational, financial, management and legal/compliance information systems to keep pace with the growth of our business. WE MAY NEED TO CHANGE THE MANNER IN WHICH WE CONDUCT OUR BUSINESS IN RESPONSE TO CHANGES IN GOVERNMENT REGULATIONS. Our subsea construction, intervention, inspection, maintenance and decommissioning operations and our oil and gas production from offshore properties, including decommissioning of such properties, are subject to and affected by various types of government regulation, including numerous federal, state and local environmental protection laws and regulations. These laws and regulations are becoming increasingly complex, stringent and expensive to comply with, and significant fines and penalties may be imposed for noncompliance. We cannot assure you that continued compliance with existing or future laws or regulations will not adversely affect our operations. CERTAIN PROVISIONS OF OUR CORPORATE DOCUMENTS AND MINNESOTA LAW MAY DISCOURAGE A THIRD PARTY FROM MAKING A TAKEOVER PROPOSAL. In addition to the 55,000 shares of preferred stock issued or issuable to Fletcher under the Agreement, our board of directors has the authority, without any action by our shareholders, to fix the rights and preferences on up to 4,945,000 shares of undesignated preferred stock, including dividend, liquidation and voting rights. In addition, our by-laws divide the board of directors into three classes. We are also subject to certain anti-takeover provisions of the Minnesota Business Corporation Act. We also have employment contracts with all of our senior officers that require cash payments in the event of a "change of control." Any or all of the provisions or factors described above may have the effect of discouraging a takeover proposal or tender offer not approved by management and the board of directors and could result in shareholders who may wish to participate in such a proposal or tender offer receiving less for their shares than otherwise might be available in the event of a takeover attempt. SPECIAL STATEMENT REGARDING FORWARD-LOOKING STATEMENTS This prospectus and the documents incorporated by reference include certain statements that may be deemed "forward-looking statements" within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. You can identify these statements by forward-looking words such as "anticipate," "believe," "budget," "could," "estimate," "expect," "forecast," "intend," "may," "plan," "potential," "should," "will" and "would" or similar words. You should read statements that contain these words carefully because they discuss our future expectations, contain projections of our future financial 6

position or results of operations or state other forward-looking information. We believe that it is important to communicate our future expectations to our investors. However, there may be events in the future that we are not able to predict or control accurately. The factors listed under "Risk Factors" provide examples of risks, uncertainties and events that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements. You should be aware that the occurrence of the events described in "Risk Factors" and elsewhere in this prospectus could have a material adverse effect on our business, results of operations and financial position. USE OF PROCEEDS We will not receive any proceeds from the sale by Fletcher of the Common Stock described in this prospectus. THE SELLING SHAREHOLDER The 7,486,907 shares of our Common Stock covered by this prospectus consist of shares of our Common Stock that may be issued to Fletcher upon conversion or redemption of or as dividends on the Series A Shares.

As used in this prospectus, "Fletcher" means Fletcher International, Ltd. and donees, pledgees, transferees or other successors-in-interest selling shares received from Fletcher International, Ltd. as a gift, pledge, distribution or other transfer not involving a sale of our stock. The selling shareholder has not held any position or office nor has it had any other material relationship with us or any of our affiliates within the past three years other than as a result of its ownership of shares of equity securities. The following table provides certain information with respect to Fletcher, including Fletcher's beneficial ownership of our Common Stock as of April 22, 2003, and as adjusted to give effect to the sale of the shares covered by this prospectus. The amounts set forth below are based upon information provided to us by representatives of Fletcher, or on our records, as of April 22, 2003, and are accurate to the best of our knowledge. As of the date of this prospectus, Fletcher has not converted or redeemed any of the Series A-1 Preferred Stock and no shares of Common Stock have been issued as dividends on the Series A-1 Preferred Stock. It is possible that Fletcher may have acquired, sold, transferred or otherwise disposed of shares of our Common Stock in transactions exempt from the registration requirements of the Securities Act of 1933, since the date on which it provided the information to us regarding the shares beneficially owned by it. This table assumes that Fletcher will offer for sale all of its shares of our Common Stock. We do not know whether Fletcher will convert or redeem the Series A Shares or whether it will offer for sale any or all of the Common Stock covered by this prospectus. Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the Commission under the Securities Exchange Act of 1934, as amended.

Pursuant to an investment advisory agreement between FAM and Fletcher, FAM has the authority to vote and dispose of the securities in these accounts. By reason of the provisions of Rule 13d-3 under the Exchange Act, Fletcher and FAM may each be deemed to beneficially own the securities registered under the registration statement of which this prospectus is a part. In addition, by virtue of Alphonse Fletcher, Jr.'s position as Chairman and Chief Executive Officer of FAM, Mr. Fletcher may be deemed to have the shared power to vote or direct the vote of, and the shared power to dispose or direct the disposition of, these securities. For these reasons, Mr. Fletcher may also be deemed to be a beneficial owner of these securities. PLAN OF DISTRIBUTION We are registering all 7,486,907 shares covered by this prospectus on behalf of Fletcher. We will not receive any of the proceeds from sales by Fletcher of the shares of Common Stock covered by this prospectus. Fletcher may sell the shares covered by this prospectus that are ultimately issued to it at different times. Fletcher will act independently of us in making decisions for the timing, manner and size of each sale. The shares offered for sale under this prospectus are listed on the Nasdaq National Market. The sales may be made on one or more exchanges or quotation systems or in the over-the-counter market or in other transactions, at prices and at terms then prevailing or at prices related to the then current market price, or at otherwise negotiated prices. The shares may be sold by one or more of, or a combination of, the following in addition to any other method permitted under this prospectus: - A block trade in which the broker-dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction; - purchases by a broker-dealer as principal and resale by this broker-dealer for its account through this prospectus; - an exchange or quotation system distribution that complies with the rules of the exchange or quotation system; - ordinary brokerage transactions and transactions in which the broker solicits purchasers; - privately negotiated transactions; - an underwritten offering; - by pledge to secure debts and other obligations; - pursuant to hedging transactions; or - by a combination of the above methods of sale. If required, this prospectus may be amended or supplemented on a continual basis to describe a specific plan of distribution. In effecting sales, broker-dealers engaged by the selling shareholder may arrange for other broker-dealers to participate in the resales. Some or all of the shares covered by this prospectus may be sold to or through an underwriter or underwriters. Any shares sold in that manner will be acquired by the underwriters for their own accounts and may be resold at different times in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. These shares may be offered to the public through underwriting syndicates represented by one or more managing underwriters or may be offered 8

to the public directly by one or more underwriters. Any public offering price and any discounts or concessions allowed or disallowed or paid to dealers may be changed at different times. Underwriters, broker-dealers or agents may receive compensation in the form of commissions, discounts or concessions from Fletcher and/or the purchasers of shares for whom such underwriters, broker-dealers or agents may act as agents or to whom they sell as principal, or both. Underwriters, broker-dealers or agents may also receive compensation from the purchasers of the shares for whom they act as agents or to whom they sell as principals, or both. Compensation for or to a particular underwriter or broker-dealer might be in excess of customary commissions and will be in amounts to be negotiated at the time of the sale. Underwriters, broker-dealers or agents and any other participating broker-dealers or Fletcher may be considered to be underwriters within the meaning of section 2(11) of the Securities Act, as amended, relating to the sales of the shares. Underwriters are defined in this section as any person who has purchased from an issuer with a view to, or offers or sells for an issuer in connection with, the distribution of any security, or participates or has a direct or indirect participation in any undertaking, or participates or has a participation in the direct or indirect underwriting of any undertaking. Any commission, discount or concession received by them and any profit on the resale of the shares purchased by them may be considered to be underwriting discounts or commissions under the Securities Act. Because Fletcher may be considered to be an underwriter within the meaning of section 2(11) of the Securities Act, Fletcher may be subject to the prospectus delivery requirements of the Securities Act. Neither the delivery of any prospectus, or any prospectus supplement, nor any other action taken by us, Fletcher or any purchaser relating to the purchase or sale of shares under this prospectus will be considered or treated as an admission that any of them is an underwriter within the meaning of the Securities Act relating to the sale of any shares. Additionally, any securities covered by this prospectus that qualify for sale through Rule 144 under the Securities Act may be sold under Rule 144 rather than through this prospectus. The shares may be sold through registered or licensed brokers or dealers if required under applicable state securities law. Additionally, in some states the shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with. Fletcher may enter into hedging transactions with broker-dealers or others who, in turn, may resell the shares in the course of hedging the positions they assume through this prospectus. Fletcher may enter into option or other transactions with broker-dealers that require the delivery to the broker-dealer of shares which the broker-dealer may then resell or transfer through this prospectus. Fletcher may also loan or pledge the shares to a broker-dealer, and the broker-dealer may sell the loaned shares, or upon a default the pledged shares, by use of this prospectus. Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the shares may not engage in market-making activities for our Common Stock during some restricted periods. Additionally, Fletcher will be subject to applicable provisions of the Exchange Act and the associated rules and regulations under the Exchange Act, including Regulation M, that may limit the timing of purchases and sales of shares of our Common Stock by Fletcher. We will make copies of this prospectus available to Fletcher and have informed Fletcher of the need for delivery of copies of this prospectus to purchasers at or before the time of any sale of the shares. We will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act upon being notified by Fletcher that any material arrangement has been entered into with a broker-dealer for the sale of shares through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer. That supplement will disclose: - the name of the selling shareholder and of the participating broker-dealer(s); - the number of shares involved; - the price at which such shares were sold; - the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable; 9

- that such broker-dealer(s) did not conduct any investigation to verify the information set out or incorporated by reference in this prospectus; and - other facts material to the transaction. We will bear all costs, expenses and fees for the registration of the shares. Fletcher will bear all commissions and discounts, if any, attributable to their individual sales of the shares. We have agreed to indemnify Fletcher and Fletcher may agree to indemnify any broker-dealer or agent that participates in transactions involving sales of the shares against some liabilities, including liabilities arising under the Securities Act. DESCRIPTION OF CAPITAL STOCK Our amended and restated articles of incorporation provide for authorized capital stock of 120,000,000 shares of Common Stock, of which 37,629,052 shares were issued and outstanding on April 22, 2003, and 5,000,000 shares of preferred stock, of which 25,000 shares are issued and outstanding.

See "Certain Anti-Takeover Provisions" below with regard to the effect that the issuance of additional shares of preferred stock might have on attempts to take over Cal Dive. CERTAIN ANTI-TAKEOVER PROVISIONS The articles of incorporation and by-laws contain a number of provisions that could make the acquisition of Cal Dive by means of a tender or exchange offer, a proxy contest or otherwise more difficult. The description of those provisions set forth below is intended to be only a summary and is qualified in its entirety by reference to the pertinent sections of the articles of incorporation and the by-laws, which are incorporated by reference into this prospectus. Classified Board of Directors; Removal of Directors. Our directors are currently divided into three classes, only one class of which is subject to re-election in any given year. The classification of directors will have the effect of making it more difficult for shareholders to change the composition of the board of directors. At least two annual meetings of shareholders generally will be required to effect a change in majority of the board of directors. Such a delay may help ensure that our directors, if confronted by a shareholder attempting 10

to force a proxy contest, a tender or exchange offer or an extraordinary corporate transaction, would have sufficient time to review the proposal as well as any available alternatives to the proposal and to act in what they believe to be the best interest of the shareholders. The classification provisions will apply to every election of directors, however, regardless of whether a change in the composition of the board of directors would be beneficial to us and our shareholders and whether a majority of our shareholders believes that such a change would be desirable. The articles of incorporation provide that our directors may only be removed by the affirmative vote of the holders of 68% of the voting power of all the then outstanding shares of stock entitled to vote generally in the election of directors (the "Voting Stock"). The classification provisions could also have the effect of discouraging a third party from initiating a proxy contest, making a tender or exchange offer or otherwise attempting to obtain control of Cal Dive, even though such an attempt might be beneficial to us and our shareholders. These provisions could thus increase the likelihood that incumbent directors will retain their positions. In addition, the classification provisions may discourage accumulations of large blocks of our Common Stock that are effected for purposes of changing the composition of the board of directors. Accordingly, shareholders could be deprived of certain opportunities to sell their shares of Common Stock at a higher market price than might otherwise be the case. Preferred Stock. The articles of incorporation authorize the board of directors to establish one or more series of preferred stock and to determine, with respect to any series of preferred stock, the terms and rights of such series, including: - the designation of the series; - the number of shares of the series, which number the board may thereafter (except where otherwise provided in the certificate of designation) increase or decrease (but not below the number of shares thereof then outstanding); - whether dividends, if any, will be cumulative or non-cumulative and the dividend rate of the series; - the dates at which dividends, if any, will be payable; - the redemption rights and price or prices, if any, for shares of the series; - the terms and amounts of any sinking fund provided for the purchase or redemption of shares of the series; - the amounts payable on shares of the series in the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of Cal Dive; - whether the shares of the series will be convertible into shares of any other class or series, or any other security, of Cal Dive or any other corporation, and, if so, the specification of the other class or series or the other security, the conversion price or prices or rate or rates, any adjustments thereof, the date or dates as of which such shares shall be convertible and all of the terms and conditions upon which such conversion may be made; - restrictions, if any, on the issuance of shares of the same series or of any other class or series; and - voting rights, if any, of the shareholder of such series, which may include the right of such shareholders to vote separately as a class on any matter. We believe that the ability of the board of directors to issue one or more series of preferred stock will provide us with flexibility in structuring possible future financings and acquisitions and in meeting other corporate needs which might arise. The authorized shares or preferred stock, as well as shares of Common Stock, will be available for issuance without further action by our shareholders, unless that action is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded. 11

Although the board of directors has no intention at the present time of doing so, it could issue a series of preferred stock that, depending on the terms of such series, might impede the completion of a proxy contest, merger, tender or exchange offer or other attempt to obtain control of Cal Dive. The board of directors will make any determination to issue such shares based on its judgment as to the best interests of Cal Dive and our shareholders. The board of directors, in so acting, could issue preferred stock having terms that could discourage an acquisition attempt through which an acquiror may be otherwise able to change the composition of the board of directors, including a tender or exchange offer or other transaction that some, or a majority of our shareholders might believe to be in their best interests or in which shareholders might receive a premium for their stock over the then current market price of such stock. No Shareholder Action by Written Consent; Special Meetings. The articles of incorporation and by-laws provide that shareholder action can be taken only at an annual or special meeting of shareholders and prohibit shareholder action by written consent in lieu of a meeting. The by-laws provide that special meetings of shareholders can be called only upon a written request by the chief executive officer or a majority of the members of the board of directors. Shareholders are not permitted to call a special meeting or to require that the board of directors call a special meeting. The provisions of the articles of incorporation and the by-laws prohibiting shareholder action by written consent may have the effect of delaying consideration of a shareholder proposal, including a shareholder proposal that a majority of shareholders believes to be in the best interest of Cal Dive, until the next annual meeting unless a special meeting is called. These provisions would also prevent the holders of a majority of the Voting Stock from unilaterally using written consents to take shareholder action. Moreover, a shareholder could not force shareholder consideration of a proposal over the opposition of the board of directors by calling a special meeting of shareholders prior to the time a majority of the board of directors believes such consideration to be appropriate. Amendment of Certain Provisions of the Articles of Incorporation and Bylaws. Under the Minnesota Business Corporation Act (the "MBCA"), the shareholders have the right to adopt, amend or repeal the by-laws and, with the approval of the board of directors, the articles of incorporation. The articles of incorporation provide that the affirmative vote of the holders of at least 80% of the voting power of the then outstanding shares of Voting Stock, voting together as a single class, and in addition to any other vote required by the articles of incorporation or by-laws, is required to amend provisions of the articles of incorporation of by-laws relating to: - the prohibition of shareholder action without a meeting; - the prohibition of shareholders calling a special meeting; - the number, election and term of our directors; - the removal of directors; and - fixing a quorum for meetings of shareholders. The vote of the holders of a majority of the voting power of the outstanding shares of Voting Stock is required to amend all other provisions of the articles of incorporation. The by-laws further provide that the by-laws may be amended by the board of directors. These super-majority voting requirements will have the effect of making more difficult any amendment by shareholders of the by-laws or of any of the provisions that such amendment would be in their best interests. Anti-Takeover Legislation. As a public corporation, we are governed by the provisions of Section 302A.673 of the MBCA. This anti-takeover provision may eventually operate to deny shareholders the receipt of a premium on their Common Stock and may also have a depressive effect on the market price of our Common Stock. Section 302A.673 prohibits a public corporation from engaging in a "business combination" with an "interested shareholder" for a period of four years after the date of the transaction in which the person became an interested shareholder, unless the business combination is approved by a committee of all of the disinterested members of our board of directors before the interested shareholder's share acquisition date. A "business combination" includes mergers, asset sales and other transaction. An "interested shareholder" is a 12

person who is the beneficial owner of 10% or more of the corporation's Voting Stock. Reference is made to the detailed terms of Section 302A.673 of the MBCA. LIMITATION ON DIRECTORS' LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS The articles of incorporation contain a provision that eliminates, to the extent currently allowed under the MBCA, the personal monetary liability of a director to Cal Dive and our shareholders for breach of fiduciary duty of care as a director, except in certain circumstances. If a director of Cal Dive were to breach such fiduciary duty of care in performing duties as a director, neither Cal Dive nor our shareholders could recover monetary damages from the director, and the only course of action available to our shareholders would be equitable remedies, such as an action to enjoin or rescind a transaction involving a breach of the fiduciary duty of care. To the extent certain claims against directors are limited to equitable remedies, this provision of the articles of incorporation may reduce the likelihood of derivative litigation against directors for breach of their fiduciary duty of care. Additionally, equitable remedies may not be effective in many situations. If a shareholder's only remedy is to enjoin the completion of the board of directors' action, this remedy would be ineffective if the shareholder does not become aware of a transaction or event until after its has been completed. In such a situation, such shareholder would not have effective remedy against the directors. Our by-laws require us to indemnify directors and officers to the fullest extent permitted under Minnesota law. The MBCA provides that a corporation organized under the Minnesota law shall indemnify any director, officer, employee or agent of the corporation made or threatened to be made a party to a proceeding, by reason of the former or present official capacity (as defined in the MBCA) of the person, against judgments, penalties, fines, settlements, and reasonable expense incurred by the person in connection with the proceedings if certain statutory standards are met. "Proceeding" means a threatened, pending or completed civil, criminal, administrative, arbitration or investigative proceeding, including one by or in the right of the corporation. Selection 302A.521 of the MBCA contains detailed terms regarding such rights of indemnification and reference is made thereto for a complete statement of such indemnification rights. All of the foregoing indemnification provisions include statements that such provisions are not to be deemed exclusive of any other right to indemnity to which a director or officer may be entitled under any bylaw, agreement, vote of shareholders or disinterested directors or otherwise.

INDEMNIFICATION OF DIRECTORS AND OFFICERS The articles of incorporation contain a provision that eliminates, to the extent currently allowed under the MBCA, the personal monetary liability of a director to Cal Dive and our shareholders for breach of fiduciary duty of care as a director, except in certain circumstances. If a director of Cal Dive were to breach such fiduciary duty of care in performing duties as a director, neither Cal Dive nor our shareholders could recover monetary damages from the director, and the only course of action available to our shareholders would be equitable remedies, such as an action to enjoin or rescind a transaction involving a breach of the fiduciary duty of care. To the extent certain claims against directors are limited to equitable remedies, this provision of the articles of incorporation may reduce the likelihood of derivative litigation against directors for breach of their fiduciary duty of care. Additionally, equitable remedies may not be effective in many situations. If a shareholder's only remedy is to enjoin the completion of the board of directors' action, this remedy would be ineffective if the shareholder does not become aware of a transaction or event until after its has been completed. In such a situation, such shareholder would not have effective remedy against the directors. Our by-laws require us to indemnify directors and officers to the fullest extent permitted under Minnesota law.

UNDERTAKINGS The undersigned Registrant hereby undertakes: To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended. To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high and of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement. To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the registration statement. PROVIDED, HOWEVER, that the first two undertakings do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Securities and Exchange Commission by the undersigned registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. That, for the purpose of determining any liability under the Securities Act of 1933, as amended, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time to be the initial bona fide offering thereof; II-3

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, as amended, each filing of the undersigned registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act of 1933, may be permitted to directors, officers and controlling persons of the undersigned registrant pursuant to the foregoing provisions, or otherwise, the undersigned registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the undersigned registrant of expenses incurred or paid by a director, officer or controlling person of the undersigned registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the undersigned registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
