            REPRESENTATIVE'S WARRANT AGREEMENT dated as of ______________, 2000
by and among DYNACS INC., a Delaware corporation (the "Company"), H.C.
WAINWRIGHT & CO., INC. and ROTH CAPITAL PARTNERS, INC. (hereinafter referred to
as the "Holders" or the "Representatives").

                              W I T N E S S E T H:

            WHEREAS, the Company proposes to issue to the Representatives or its
designees warrants ("Warrants") to purchase up to an aggregate 2,500,000 shares
of common stock, par value $0.01 per share, of the Company ("Common Stock"); and

            WHEREAS, the Representatives have agreed pursuant to the
underwriting agreement (the "Underwriting Agreement") dated as of the date
hereof among H.C. Wainwright & Co., Inc. and Roth Capital Partners, Inc., as the
Representatives of the several Underwriters named in Schedule A thereto, and the
Company to act as the Representatives in connection with the Company's proposed
public offering of up to 2,500,000 shares of Common Stock at a public offering
price of $[______] per share of Common Stock (the "Public Offering"); and

            WHEREAS, the Warrants to be issued pursuant to this Agreement will
be issued on the Closing Date (as such term is defined in the Underwriting
Agreement) by the Company to the Representatives in consideration for, and as
part of the Representative's compensation in connection with, the
Representatives acting as the Representatives pursuant to the Underwriting
Agreement;

            NOW, THEREFORE, in consideration of the premises, the payment by the
Representatives to the Company of an aggregate of twenty-five dollars ($25.00),
the agreements herein set forth and other good and valuable consideration,
hereby acknowledged, the parties hereto agree as follows:
<PAGE>   3

            SECTION 1. Grant. The Representatives are hereby granted the right
to purchase, at any time from ___________, 2001 [one year from the date hereof],
until 5:30 P.M., New York time, on ______________, 2005 [five years from the
effective date of the registration statement], up to an aggregate of 250,000
shares of Common Stock (the "Shares") at an initial exercise price (subject to
adjustment as provided in Section 8 hereof) of $[_____] per share [120% of the
public offering price per share] of Common Stock subject to the terms and
conditions of this Agreement. Except as set forth herein, the Shares issuable
upon exercise of the Warrants are in all respects identical to the shares of
Common Stock being purchased by the Underwriters for resale to the public
pursuant to the terms and provisions of the Underwriting Agreement.

            SECTION 2. Warrant Certificates. The warrant certificates (the
"Warrant Certificates") delivered and to be delivered pursuant to this Agreement
shall be in the form set forth in Exhibit A, attached hereto and made a part
hereof, with such appropriate insertions, omissions, substitutions, and other
variations as required or permitted by this Agreement.

            SECTION 3. Exercise of Warrant.

                  Section 3.1 Method of Exercise. The Warrants initially are
exercisable at an aggregate initial exercise price (subject to adjustment as
provided in Section 8 hereof) per share of Common Stock set forth in Section 6
hereof payable by certified or official bank check in New York Clearing House
funds. Upon surrender of a Warrant Certificate with the annexed Form of Election
to Purchase duly executed, together with payment of the Exercise Price (as
hereinafter defined) for the shares of Common Stock purchased at the Company's
principal offices in Palm Harbor, Florida (presently located at 3511 US Highway
19N, Suite 300, Palm Harbor, Florida 34684) the registered holder of a Warrant
Certificate ("Holder" or "Holders") shall be entitled to receive a certificate
or certificates for the shares of Common Stock so purchased. The purchase rights
represented by each Warrant Certificate are exercisable at the option of the
Holder thereof, in whole or in part (but not as to fractional shares of the
Common

                                       2
<PAGE>   4

Stock underlying the Warrants). Warrants may be exercised to purchase all or
part of the shares of Common Stock represented thereby. In the case of the
purchase of less than all the shares of Common Stock purchasable under any
Warrant Certificate, the Company shall cancel said Warrant Certificate upon the
surrender thereof and shall execute and deliver a new Warrant Certificate of
like tenor for the balance of the shares of Common Stock purchasable thereunder.

                  Section 3.2 Exercise by Surrender of Warrant. In addition to
the method of payment set forth in Section 3.1 and in lieu of any cash payment
required thereunder, the Holders of the Warrants shall have the right at any
time and from time to time to exercise the Warrants in full or in part by
surrendering the Warrant Certificate in the manner specified in Section 3.1 in
exchange for the number of Shares equal to the product of (x) the number of
Shares as to which the Warrants are being exercised multiplied by (y) a
fraction, the numerator of which is the Market Price (as defined in Section 3.3
below) of the Shares less the Exercise Price and the denominator of which is
such Market Price. Solely for the purposes of this paragraph, Market Price shall
be calculated either (i) on the date which the form of election attached hereto
is deemed to have been sent to the Company pursuant to Section 13 hereof
("Notice Date") or (ii) as the average of the Market Prices for each of the five
trading days preceding the Notice Date, whichever of (i) or (ii) is greater.

                  Section 3.3 Definition of Market Price. As used herein, the
phrase "Market Price" at any date shall be deemed to be the last reported sale
price, or, in case no such reported sale takes place on such day, the average of
the last reported sale prices for the last three (3) trading days, in either
case as officially reported by the principal securities exchange on which the
Common Stock is listed or admitted to trading or by the Nasdaq National Market
or Nasdaq SmallCap market (as the case may be "Nasdaq"), or, if the Common Stock
is not listed or admitted to trading on any national securities exchange or
quoted by Nasdaq, the average closing bid price as furnished by the NASD through
Nasdaq or similar organization if Nasdaq is no longer reporting such
information, or if the Common Stock is not quoted on Nasdaq, as

                                       3
<PAGE>   5

determined in good faith by resolution of the Board of Directors of the Company,
based on the best information available to it.

            SECTION 4. Issuance of Certificates. Upon the exercise of the
Warrants, the issuance of certificates for shares of Common Stock and/or other
securities, properties or rights underlying such Warrants, shall be made
forthwith (and in any event within five (5) business days thereafter) without
charge to the Holders thereof including, without limitation, any tax which may
be payable in respect of the issuance thereof, and such certificates shall
(subject to the provisions of Sections 5 and 7 hereof) be issued in the name of,
or in such names as may be directed by, the Holders thereof; provided, however,
that the Company shall not be required to pay any tax which may be payable in
respect of any transfer involved in the issuance and delivery of any such
certificates in a name other than that of the Holders, and the Company shall not
be required to issue or deliver such certificates unless or until the person or
persons requesting the issuance thereof shall have paid to the Company the
amount of such tax or shall have established to the satisfaction of the Company
that such tax has been paid.

            The Warrant Certificates and the certificates representing the
Shares underlying the Warrants (and/or other securities, property or rights
issuable upon the exercise of the Warrants) shall be executed on behalf of the
Company by the manual or facsimile signature of the then Chairman or Vice
Chairman of the Board of Directors or President or Vice President of the
Company. Warrant Certificates shall be dated the date of execution by the
Company upon initial issuance, division, exchange, substitution or transfer.

            SECTION 5. Restriction On Transfer of Warrants. The Holders of a
Warrant Certificate, by its acceptance thereof, covenants and agrees that the
Warrants are being acquired as an investment and not with a view to the
distribution thereof; that the Warrants may not be sold, transferred, assigned,
hypothecated or otherwise disposed of, in whole or in part, for a period of one
(1) year from the date hereof, except to officers of the Representatives.

            SECTION 6. Exercise Price.

                  Section 6.1 Initial and Adjusted Exercise Price. Except as
otherwise provided in Section 8 hereof, the initial exercise price of each
Warrant shall be $[____] per share [120% of the public offering price per share]
of Common Stock. The adjusted exercise price shall be the price which shall
result from time to time from any and all adjustments of the initial exercise
price in accordance with the provisions of Section 8 hereof.

                  Section 6.2 Exercise Price. The term "Exercise Price" herein
shall mean the initial exercise price or the adjusted exercise price, depending
upon the context.

            SECTION 7. Registration Rights.

                  Section 7.1 Registration Under the Securities Act of 1933.
None of the Warrants, the Shares, and any other securities issuable upon
exercise of the Warrants have been registered under the Securities Act of 1933,
as amended (the "Act"), pursuant to the Company's Registration Statement on Form
S-1 (Registration No. _________) (the "Registration Statement"). All of the
representations and warranties of the Company contained in the Underwriting
Agreement relating to the Registration Statement, the Preliminary Prospectus and
Prospectus (as such terms are defined in the Underwriting Agreement) and made as
of the dates provided therein, are hereby incorporated by reference.
Accordingly, the Warrants, certificates representing the Shares underlying the
Warrants, and any of the other securities issuable upon exercise of the Warrants
(collectively, the "Warrant Securities") shall bear the following legend:

                  The securities represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended
                  ("Act"), and may not be offered or sold except pursuant to (i)
                  an effective registration statement under the Act, (ii) to the
                  extent applicable, Rule 144 under the Act (or any similar rule
                  under such Act relating to the disposition of securities), or
                  (iii) an opinion of counsel, if such opinion shall be
                  reasonably satisfactory to counsel to

                                       5
<PAGE>   7

                  the issuer, that an exemption from registration under such Act
                  is available.

                  Section 7.2 Piggyback Registration. If, at any time commencing
after the date hereof and expiring six (6) years from the date hereof, the
Company proposes to register any of its securities under the Act (other than in
connection with a merger or pursuant to Forms S-4 or S-8) it will give written
notice by registered mail, at least thirty (30) days prior to the filing of each
such registration statement, to the Representatives and to all other Holders of
the Warrants and/or the Warrant Securities of its intention to do so. If the
Representatives or other Holders of the Warrants and/or Warrant Securities
notify the Company within twenty (20) days after receipt of any such notice of
its or their desire to include any such securities in such proposed registration
statement, the Company shall afford the Representatives and such Holders of the
Warrants and/or Warrant Securities the opportunity to have any such Warrant
Securities registered under such registration statement (sometimes referred to
herein as the "Piggyback Registration").

            Notwithstanding the provisions of this Section 7.2, the Company
shall have the right at any time after it shall have given written notice
pursuant to this Section 7.2 (irrespective of whether a written request for
inclusion of any such securities shall have been made) to elect not to file any
such proposed registration statement, or to withdraw the same after the filing
but prior to the effective date thereof.

                  Section 7.3 Demand Registration.

                  (a) At any time commencing after the date hereof and expiring
five (5) years from the effective date of the Public Offering, the Holders of
the Warrants and/or Warrant Securities representing a "Majority" (as hereinafter
defined) of such securities (assuming the exercise of all of the Warrants) shall
have the right (which right is in addition to the registration rights under
Section 7.2 hereof), exercisable by written notice to the Company, to have the
Company prepare and file with the Securities and Exchange Commission (the
"Commission"),

                                       6
<PAGE>   8

on one occasion, a registration statement and such other documents, including a
prospectus, as may be necessary in the opinion of both counsel for the Company
and counsel for the Representatives and Holders, in order to comply with the
provisions of the Act, so as to permit a public offering and sale of their
respective Warrant Securities for nine (9) consecutive months by such Holders
and any other Holders of the Warrants and/or Warrant Securities who notify the
Company within ten (10) days after receiving notice from the Company of such
request.

                  (b) In addition to the registration rights under Section 7.2
hereof and subsection (a) of this Section 7.3, at any time commencing after the
date hereof and expiring five (5) years after the effective date of the Public
Offering, any Holder of Warrants and/or Warrant Securities shall have the right,
exercisable by written request to the Company, to have the Company prepare and
file, on one occasion, with the Commission a registration statement so as to
permit a public offering and sale for nine (9) consecutive months by any such
Holder of its Warrant Securities, provided, however, that the provisions of
Section 7.4(b) hereof shall not apply to any such registration request and
registration and all costs incident thereto shall be at the expense of the
Holder or Holders making such request.

                  (c) The Company covenants and agrees to give written notice of
any registration request under this Section 7.3 by any Holder or Holders to all
other registered Holders of the Warrants and the Warrant Securities within ten
(10) days from the date of the receipt of any such registration request.

                  Section 7.4 Covenants of the Company With Respect to
Registration. In connection with any registration under Section 7.2 or 7.3
hereof, the Company covenants and agrees as follows:

                  (a) The Company shall use its best efforts to file a
registration statement within forty-five (45) days of receipt of any demand
therefor, shall use its best efforts to have any registration statements
declared effective at the earliest possible time, and shall

                                       7
<PAGE>   9

furnish each Holder desiring to sell Warrant Securities such number of
prospectuses as shall reasonably be requested.

                  (b) The Company shall pay all costs (excluding fees and
expenses of Holders' counsel, filing fees and any underwriting or selling
commissions), fees and expenses in connection with all registration statements
filed pursuant to Section 7.2 and 7.3(a) hereof including, without limitation,
the Company's legal and accounting fees, printing expenses and blue sky fees and
expenses. The Holders shall pay all costs, fees and expenses in connection with
any registration statement filed pursuant to Section 7.3(b) hereof. If the
Company shall fail to comply with the provisions of Section 7.4, the Company
shall, in addition to any other equitable or other relief available to the
Holders, be liable for any or all incidental or special damages sustained by the
Holders requesting registration of their Warrant Securities.

                  (c) The Company will take all necessary action which may be
required in qualifying or registering the Warrant Securities included in a
registration statement for offering and sale under the securities or blue sky
laws of such states as reasonably are requested by the Holders, provided that
the Company shall not be obligated to execute or file any general consent to
service of process or to qualify as a foreign corporation to do business under
the laws of any such jurisdiction.

                  (d) The Company shall indemnify the Holders of the Warrant
Securities to be sold pursuant to any registration statement and each person, if
any, who controls such Holders within the meaning of Section 15 of the Act or
Section 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), against all loss, claim, damage, expense or liability (including all
expenses reasonably incurred in investigating, preparing or defending against
any claim whatsoever) to which any of them may become subject under the Act, the
Exchange Act or otherwise, arising from such registration statement but only to
the same extent and with the same effect as the provisions pursuant to which the
Company has

                                       8
<PAGE>   10

agreed to indemnify each of the Underwriters contained in Section 7 of the
Underwriting Agreement.

                  (e) The Holders of the Warrant Securities to be sold pursuant
to a registration statement, and their successors and assigns, shall severally,
and not jointly, indemnify the Company, its officers and directors and each
person, if any, who controls the Company within the meaning of Section 15 of the
Act or Section 20(a) of the Exchange Act, against all loss, claim, damage or
expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which
they may become subject under the Act, the Exchange Act or otherwise, arising
from information furnished by or on behalf of such Holders, or their successors
or assigns, for specific inclusion in such registration statement to the same
extent and with the same effect as the provisions contained in Section 7 of the
Underwriting Agreement pursuant to which the Underwriters have agreed to
indemnify the Company.

                  (f) Nothing contained in this Agreement shall be construed as
requiring the Holders to exercise their Warrants prior to the initial filing of
any registration statement or the effectiveness thereof.

                  (g) The Company shall not permit the inclusion of any
securities other than the Warrant Securities to be included in any registration
statement filed pursuant to Section 7.3 hereof, or permit any other registration
statement to be or remain effective during the effectiveness of a registration
statement filed pursuant to Section 7.3 hereof, without the prior written
consent of the Holders of the Warrants and Warrant Securities representing a
Majority of such securities.

                  (h) The Company shall furnish to each Holder participating in
the offering and to each underwriter, if any, a signed counterpart, addressed to
such Holder or underwriter, of (i) an opinion of counsel to the Company, dated
the effective date of such

                                       9
<PAGE>   11

registration statement (and, if such registration includes an underwritten
public offering, an opinion dated the date of the closing under the underwriting
agreement), and (ii) a "cold comfort" letter dated the effective date of such
registration statement (and, if such registration includes an underwritten
public offering, a letter dated the date of the closing under the underwriting
agreement) signed by the independent public accountants who have issued a report
on the Company's financial statements included in such registration statement,
in each case covering substantially the same matters with respect to such
registration statement (and the prospectus included therein) and, in the case of
such accountants' letter, with respect to events subsequent to the date of such
financial statements, as are customarily covered in opinions of issuer's counsel
and in accountants' letters delivered to underwriters in underwritten public
offerings of securities.

                  (i) The Company shall, as soon as practicable after the
effective date of the registration statement, and in any event within 15 months
thereafter, make "generally available to its security holders" (within the
meaning of Rule 158 under the Act) an earnings statement (which need not be
audited) complying with Section 11(a) of the Act and covering a period of at
least 12 consecutive months beginning after the effective date of the
registration statement. The Company shall deliver promptly to each Holder
participating in the offering requesting the correspondence described below and
to the managing underwriters, copies of all correspondence between the
Commission and the Company, its counsel or auditors with respect to the
registration statement and permit each Holder and underwriter to do such
investigation, upon reasonable advance notice, with respect to information
contained in or omitted from the registration statement as it deems reasonably
necessary to comply with applicable securities laws or rules of the National
Association of Securities Dealers, Inc. ("NASD"). Such investigation shall
include access to books, records and properties and opportunities to discuss the
business of the Company with its officers and independent auditors, all to such
reasonable extent and at such reasonable times and as often as any such Holder
or underwriter shall reasonably request.

                                       10
<PAGE>   12

                  (j) The Company shall enter into an underwriting agreement
with the managing underwriters selected for such underwriting by Holders holding
a Majority of the Warrant Securities requested to be included in such
underwriting, which may be the Representatives. Such agreement shall be
satisfactory in form and substance to the Company, each Holder and such managing
underwriter(s), and shall contain such representations, warranties and covenants
by the Company and such other terms as are customarily contained in agreements
of that type used by the managing underwriter(s). The Holders shall be parties
to any underwriting agreement relating to an underwritten sale of their Warrant
Securities and may, at their option, require that any or all the
representations, warranties and covenants of the Company to or for the benefit
of such underwriter(s) shall also be made to and for the benefit of such
Holders. Such Holders shall not be required to make any representations or
warranties to or agreements with the Company or the underwriter(s) except as are
customarily made by selling securityholders in underwritten offerings.

                  (k) In addition to the Warrant Securities, upon the written
request therefor by any Holders, the Company shall include in the registration
statement any other securities of the Company held by such Holders as of the
date of filing of such registration statement, including without limitation
restricted shares of Common Stock, options, warrants or any other securities
convertible into shares of Common Stock.

                  (l) For purposes of this Agreement, the term "Majority" in
reference to the Holders of Warrants or Warrant Securities, shall mean in excess
of fifty percent (50%) of the then outstanding Warrants or Warrant Securities
that (i) are not held by the Company, an affiliate, officer, creditor, employee
or agent thereof or any of their respective affiliates, members of their family,
persons acting as nominees or in conjunction therewith and (ii) have not been
resold to the public pursuant to a registration statement filed with the
Commission under the Act.

            SECTION 8. Adjustments to Exercise Price and Number of Securities.

                  Section 8.1 Subdivision and Combination. In case the Company
shall at any time subdivide or combine the outstanding shares of Common Stock,
the Exercise Price shall forthwith be proportionately decreased in the case of
subdivision or increased in the case of combination.

                  Section 8.2 Stock Dividends and Distributions. In case the
Company shall pay a dividend in, or make a distribution of, shares of Common
Stock or of the Company's capital stock convertible into Common Stock, the
Exercise Price shall forthwith be proportionately decreased. An adjustment made
pursuant to this Section 8.2 shall be made as of the record date for the subject
stock dividend or distribution.

                  Section 8.3 Adjustment in Number of Securities. Upon each
adjustment of the Exercise Price pursuant to the provisions of this Section 8,
the number of Warrant Securities issuable upon the exercise at the adjusted
exercise price of each Warrant shall be adjusted to the nearest whole number by
multiplying a number equal to the Exercise Price in effect immediately prior to
such adjustment by the number of Warrant Securities issuable upon exercise of
the Warrants immediately prior to such adjustment and dividing the product so
obtained by the adjusted Exercise Price.

                  Section 8.4 Definition of Common Stock. For the purpose of
this Agreement, the term "Common Stock" shall mean (i) the class of stock
designated as Common Stock in the Articles of Incorporation of the Company as
may be amended as of the date hereof, or (ii) any other class of stock resulting
from successive changes or reclassifications of such Common Stock consisting
solely of changes in par value, or from par value to no par value, or from no
par value to par value.

                  Section 8.5 Merger or Consolidation. In case of any
consolidation of the Company with, or merger of the Company with, or merger of
the Company into, another corporation (other than a consolidation or merger
which does not result in any reclassification or change of the outstanding
Common Stock), the corporation formed by such consolidation or merger shall
execute and deliver to the Holders a supplemental warrant agreement providing
that the holder of each Warrant then outstanding or to be outstanding shall have
the right thereafter (until the expiration of such Warrant) to receive, upon
exercise of such Warrant, the kind and amount of shares of stock and other
securities and property receivable upon such consolidation or merger, by a
holder of the number of shares of Common Stock of the Company for which such
Warrant might have been exercised immediately prior to such consolidation,
merger, sale or transfer. Such supplemental warrant agreement shall provide for
adjustments which shall be identical to the adjustments provided in this Section
8. The above provision of this subsection shall similarly apply to successive
consolidations or mergers.

                  Section 8.6 No Adjustment of Exercise Price in Certain Cases.
No adjustment of the Exercise Price shall be made:

                        Upon the issuance or sale of the Warrants or the shares
            of Common Stock issuable upon the exercise of the Warrants;

                        If the amount of said adjustment shall be less than two
            cents (2(cent)) per Warrant Security, provided, however, that in
            such case any adjustment that would otherwise be required then to be
            made shall be carried forward and shall be made at the time of and
            together with the next subsequent adjustment which, together with
            any adjustment so carried forward, shall amount to at least two
            cents (2(cent)) per Warrant Security.

            SECTION 9. Exchange and Replacement of Warrant Certificates. Each

by the

                                       13
<PAGE>   15

registered Holders at the principal executive office of the Company, for a new
Warrant Certificate of like tenor and date representing in the aggregate the
right to purchase the same number of Warrant Securities in such denominations as
shall be designated by the Holders thereof at the time of such surrender.

            Upon receipt by the Company of evidence reasonably satisfactory to
it of the loss, theft, destruction or mutilation of any Warrant Certificate,
and, in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if
mutilated, the Company will make and deliver a new Warrant Certificate of like
tenor, in lieu thereof.

            SECTION 10. Elimination of Fractional Interests. The Company shall
not be required to issue certificates representing fractions of shares of Common
Stock upon the exercise of the Warrants, nor shall it be required to issue scrip
or pay cash in lieu of fractional interests, it being the intent of the parties
that all fractional interests shall be eliminated by rounding any fraction up to
the nearest whole number of shares of Common Stock or other securities,
properties or rights.

            SECTION 11. Reservation and Listing of Securities. The Company shall
at all times reserve and keep available out of its authorized shares of Common
Stock, solely for the purpose of issuance upon the exercise of the Warrants,
such number of shares of Common Stock or other securities, properties or rights
as shall be issuable upon the exercise thereof. The Company covenants and agrees
that, upon exercise of the Warrants and payment of the Exercise Price therefor,
all shares of Common Stock and other securities issuable upon such exercise
shall be duly and validly issued, fully paid, non-assessable and not subject to
the preemptive rights of any stockholder. As long as the Warrants shall be
outstanding, the Company shall use its best efforts to cause all shares of
Common Stock issuable upon the exercise of the Warrants to be

                                       14
<PAGE>   16

listed (subject to official notice of issuance) on all securities exchanges on
which the Common Stock issued to the public in connection herewith may then be
listed and/or quoted.

            SECTION 12. Notices to Warrant Holders. Nothing contained in this
Agreement shall be construed as conferring upon the Holders the right to vote or
to consent or to receive notice as a stockholder in respect of any meetings of
stockholders for the election of directors or any other matter, or as having any
rights whatsoever as a stockholder of the Company. If, however, at any time
prior to the expiration of the Warrants and their exercise, any of the following
events shall occur:

                  (i) the Company shall take a record of the holders of its
            shares of Common Stock for the purpose of entitling them to receive
            a dividend or distribution payable otherwise than in cash, or a cash
            dividend or distribution payable otherwise than out of current or
            retained earnings, as indicated by the accounting treatment of such
            dividend or distribution on the books of the Company; or

                  (ii) the Company shall offer to all the holders of its Common
            Stock any additional shares of capital stock of the Company or
            securities convertible into or exchangeable for shares of capital
            stock of the Company, or any option, right or warrant to subscribe
            therefor; or

                  (iii) a dissolution, liquidation or winding up of the Company
            (other than in connection with a consolidation or merger) or a sale
            of all or substantially all of its property, assets and business as
            an entirety shall be proposed;

then, in any one or more of said events, the Company shall give written notice
of such event at least fifteen (15) days prior to the date fixed as a record
date or the date of closing the transfer books for the determination of the
stockholders entitled to such dividend, distribution,

                                       15
<PAGE>   17

convertible or exchangeable securities or subscription rights, or entitled to
vote on such proposed dissolution, liquidation, winding up or sale. Such notice
shall specify such record date or the date of closing the transfer books, as the
case may be. Failure to give such notice or any defect therein shall not affect
the validity of any action taken in connection with the declaration or payment
of any such dividend, or the issuance of any convertible or exchangeable
securities, or subscription rights, options or warrants, or any proposed
dissolution, liquidation, winding up or sale.

            SECTION 13. Notices.

            All notices, requests, consents and other communications hereunder
shall be in writing and shall be deemed to have been duly made and sent when
delivered, or mailed by registered or certified mail, return receipt requested:

                  (i) If to the registered Holders of the Warrants, to the
            address of such Holders as shown on the books of the Company; or

                  (ii) If to the Company, to the address set forth in Section 3
            hereof or to such other address as the Company may designate by
            notice to the Holders.

            SECTION 14. Supplements and Amendments. The Company and the
Representatives may from time to time supplement or amend this Agreement without
the approval of any Holders of Warrant Certificates (other than the
Representative) in order to cure any ambiguity, to correct or supplement any
provision contained herein which may be defective or inconsistent with any
provisions herein, or to make any other provisions in regard to matters or
questions arising hereunder which the Company and the Representatives may deem
necessary or desirable and which the Company and the Representatives deem shall
not adversely affect the interests of the Holders of Warrant Certificates.

            SECTION 15. Successors. All the covenants and provisions of this
Agreement shall be binding upon and inure to the benefit of the Company, the
Holders and their respective successors and assigns hereunder.

            SECTION 16. Termination. This Agreement shall terminate at the close
of business on ______________, 2005. Notwithstanding the foregoing, the
indemnification provisions of Section 7 shall survive such termination until the
close of business on ______________, 2011.

            SECTION 17. Governing Law; Submission to Jurisdiction. This
Agreement and each Warrant Certificate issued hereunder shall be deemed to be a
contract made under the laws of the State of New York and for all purposes shall
be construed in accordance with the laws of said State without giving effect to
the rules of said State governing the conflicts of laws.

            The Company, the Representatives and the Holders hereby agree that
any action, proceeding or claim against it arising out of, or relating in any
way to, this Agreement shall be brought and enforced in the courts of the State
of New York or of the United States of America for the Southern District of New
York, and irrevocably submits to such jurisdiction, which jurisdiction shall be
exclusive. The Company, the Representatives and the Holders hereby irrevocably
waive any objection to such exclusive jurisdiction or inconvenient forum. Any
such process or summons to be served upon any of the Company, the
Representatives and the Holders (at the option of the party bringing such
action, proceeding or claim) may be served by transmitting a copy thereof, by
registered or certified mail, return receipt requested, postage prepaid,
addressed to it at the address set forth in Section 13 hereof. Such mailing
shall be deemed personal service and shall be legal and binding upon the party
so served in any action, proceeding or claim. The Company, the Representatives
and the Holders agree that the prevailing party(ies) in any such action or
proceeding shall be entitled to recover from the other

                                       17

party(ies) all of its/their reasonable legal costs and expenses relating to such
action or proceeding and/or incurred in connection with the preparation
therefor.

            SECTION 18. Entire Agreement; Modification. This Agreement
(including the Underwriting Agreement to the extent portions thereof are
referred to herein) contains the entire understanding between the parties hereto
with respect to the subject matter hereof and may not be modified or amended
except by a writing duly signed by the party against whom enforcement of the
modification or amendment is sought.

            SECTION 19. Severability. If any provision of this Agreement shall
be held to be invalid or unenforceable, such invalidity or unenforceability
shall not affect any other provision of this Agreement.

            SECTION 20. Captions. The caption headings of the Sections of this
Agreement are for convenience of reference only and are not intended, nor should
they be construed as, a part of this Agreement and shall be given no substantive
effect.

            SECTION 21. Benefits of this Agreement. Nothing in this Agreement
shall be construed to give to any person or corporation other than the Company
and the Representatives and any other registered Holders of the Warrant
Certificates or Warrant Securities any legal or equitable right, remedy or claim
under this Agreement; and this Agreement shall be for the sole benefit of the
Company and the Representatives and any other registered Holders of Warrant
Certificates or Warrant Securities.

            SECTION 22. Counterparts. This Agreement may be executed in any
number of counterparts and each of such counterparts shall for all purposes be
deemed to be an original, and such counterparts shall together constitute but
one and the same instrument.

                               WARRANT CERTIFICATE

            This Warrant Certificate certifies that , or registered assigns, is
the registered holder of ________Warrants to purchase initially, at any time
from ___________, 2001 [one year from the effective date of the Registration
Statement] until 5:30 p.m. New York time on ____________, 2005 [five years from
the effective date of the Registration Statement] ("Expiration Date"), up to
__________ fully-paid and non-assessable shares of common stock, ("Common
Stock") of DYNACS INC., a Delaware corporation (the "Company"), (one share of
Common Stock referred to individually as a "Security" and collectively as the
"Securities") at the initial exercise price, subject to adjustment in certain
events (the "Exercise Price"), of $____ per share [120% of the initial public
offering price per share] of Common Stock upon surrender of this Warrant
Certificate and payment of the Exercise Price at an office or agency of the
Company, but subject to the conditions set forth herein and in the warrant
agreement dated as of ______________, 2000 among the Company, H.C. WAINWRIGHT &
CO., INC. and ROTH CAPITAL PARTNERS, INC. (the "Warrant Agreement"). Payment of
the Exercise Price shall be made by certified or official bank check in New York
Clearing House funds payable to the order of the Company.

            No Warrant may be exercised after 5:30 p.m., New York time, on the
Expiration Date, at which time all Warrants evidenced hereby, unless exercised
prior thereto, hereby shall thereafter be void.
<PAGE>   22

            The Warrants evidenced by this Warrant Certificate are part of a
duly authorized issue of Warrants issued pursuant to the Warrant Agreement,
which Warrant Agreement is hereby incorporated by reference in and made a part
of this instrument and is hereby referred to for a description of the rights,
limitation of rights, obligations, duties and immunities thereunder of the
Company and the Holders (the words "holder" or "Holders" meaning the registered
holder or registered Holders) of the Warrants.

            The Warrant Agreement provides that upon the occurrence of certain
events the Exercise Price and the type and/or number of the Company's securities
issuable thereupon may, subject to certain conditions, be adjusted. In such
event, the Company will, at the request of the holder, issue a new Warrant
Certificate evidencing the adjustment in the Exercise Price and the number
and/or type of securities issuable upon the exercise of the Warrants; provided,
however, that the failure of the Company to issue such new Warrant Certificates
shall not in any way change, alter, or otherwise impair, the rights of the
holder as set forth in the Warrant Agreement.

            Upon due presentment for registration of transfer of this Warrant
Certificate at an office or agency of the Company, a new Warrant Certificate or
Warrant Certificates of like tenor and evidencing in the aggregate a like number
of Warrants shall be issued to the transferee(s) in exchange for this Warrant
Certificate, subject to the limitations provided herein and in the Warrant
Agreement, without any charge except for any tax or other governmental charge
imposed in connection with such transfer.

            Upon the exercise of less than all of the Warrants evidenced by this
Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such number of unexercised Warrants.

            The Company may deem and treat the registered Holders hereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, and of any distribution to the Holders hereof, and for all
other purposes, and the Company shall not be affected by any notice to the
contrary.

            All terms used in this Warrant Certificate which are defined in the
Warrant Agreement shall have the meanings assigned to them in the Warrant
Agreement.

                    HOM8XXE-197725G

Dear Mr. Ramakrishnan,

This letter is intended to provide supplemental information in regards to the
recent accounting changes Boeing-Houston has completed, and specifically how
they affect our subcontract with Dynacs. The primary change is to the current
reporting and invoicing process.

Exhibit B dated 01/31/00 has bee revised to account for the changes in
accounting, specifically section 5.0 Employee Reporting. Please read this
section carefully. Note that all references to work orders have been eliminated.
Exhibit B-2 (Work Order Charge Numbers) is deleted in its entirety. Rather than
the 100 or so work orders authorized on the contract, we have elected to
categorize work into six broad categories, Design, Development, Test and
Engineering (DDT&E), Integration and Operations (I & 0), Technical Definition,
Sustaining Engineering, Multi Element Integration Testing (MEIT) and Post
Production Support (PPS). Each of the six categories has a three alpha prefix,
which identifies the category being worked. Your employees receive the work
authorization (CAA) from the Boeing Technical Representative (BTR). Dynacs
employees are authorized to work any CAA authorized by a BTR with the following
prefix:

Material Activity ID's

GTM (DDT&E)
GTN (I&O)
GTR (Tech Def)
GTT (Sustaining Engineering)
GTU (MEIT)
GTV (PPS)

Activity ID No.'s with a prefix other then those listed above are not authorized
at this time.

When submitting weekly and monthly reports, you are now required to subtotal the
data at the Material Activity ID level. See the attached sample weekly report.
In addition you will be required to submit the weekly report with each invoice.

<PAGE>   79

We do anticipate some additional adjustments, due to our accounting changes that
may or may not affect your contract. I will advise you of those changes as soon
as practical. If you have any questions regarding this letter, please don't
hesitate to call.

Sincerely,

/S/ EDEN WILLIAMS

To recap our previous letter, as a result of changes in our accounting and
purchasing systems, it became necessary to re-issue all our purchase contracts
with suppliers. The only changes to the previous purchase contract that you need
to implement are as follows:

All correspondence and invoices must use the above Boeing Purchase Order number.
Correspondence and invoices that reference the previous contract number may not
be processed properly.

All Invoices must be sent to the following address (requirements for information
copies to our Houston buyers or other Houston point of contract remain
unchanged.):

The Boeing Company
5301 Bolsa Avenue
Huntington Beach, CA 92647-2099
Attn: Accounts Payable
Mail Code: H014-B419

You may notice some other differences in this purchase order -- these are not
intended to nor do they affect our underlying agreement as expressed in the
previous purchase contract. Some of these differences include:

<PAGE>   81

a.      The new purchase order may show a lower total value than the original
        contract. This is the result of subtracting payments made under the old
        system, from the total; the difference in value will be paid as per the
        terms of the purchase contract. The new order shows the reconciliation
        between the old and new value by line item. Again the total of the two
        numbers should equal our previous purchase contract values.

b.      The new purchase order may show only one line item, when there were
        multiple line items. Again, this has been addressed in the body or
        comments section of the new purchase order. There is no intention to
        change the number of line items or any quantities listed in the purchase
        contract.

c.      There is a different handling of certain accounting lines or codes in
        the new purchase order. These should make no significant difference to
        you unless you have been reporting information to us using our lines of
        accounting. In this case, you will continue to do so, but use the new
        accounting information. This will not affect most suppliers.

If you have any questions, please contact the undersigned.

Sincerely,

/S/ EDEN WILLIAMS
