inure to the benefit of the permitted successors and permitted assigns of the
parties hereto.

                  3.4. This Escrow Agreement is the final expression of, and
contains the entire agreement between, the parties with respect to the subject
matter hereof and supersedes all prior understandings with respect thereto. This

the parties to be charged or by their respective agents duly authorized in
writing or as otherwise expressly permitted herein.

                  3.5. Whenever required by the context of this Escrow
Agreement, the singular shall include the plural and masculine shall include the
feminine. This Escrow Agreement shall not

                                       3
<PAGE>   4
be construed as if it had been prepared by one of the parties, but rather as if
both parties had prepared the same. Unless otherwise indicated, all references
to Articles are to this Escrow Agreement.

                  3.6. The parties hereto expressly agree that this Escrow
Agreement shall be governed by, interpreted under and construed and enforced in
accordance with the laws of the State of New York. Except as expressly set forth
herein, any action to enforce, arising out of, or relating in any way to, any
provisions of this Escrow Agreement shall be brought in the Federal or state
courts of New York, New York as is more fully set forth in the Purchase

                  3.7. The Escrow Agent's duties hereunder may be altered,
amended, modified or revoked only by a writing signed by the Company, Purchaser
and the Escrow Agent.

                  3.8. The Escrow Agent shall be obligated only for the
performance of such duties as are specifically set forth herein and may rely and
shall be protected in relying or refraining from acting on any instrument
reasonably believed by the Escrow Agent to be genuine and to have been signed or
presented by the proper party or parties. The Escrow Agent shall not be
personally liable for any act the Escrow Agent may do or omit to do hereunder as
the Escrow Agent while acting in good faith, excepting only its own gross
negligence or willful misconduct, and any act done or omitted by the Escrow
Agent pursuant to the advice of the Escrow Agent's attorneys-at-law (other than
Escrow Agent itself) shall be conclusive evidence of such good faith.

                  3.9. The Escrow Agent is hereby expressly authorized to
disregard any and all warnings given by any of the parties hereto or by any
other person or corporation, excepting only orders or process of courts of law
and is hereby expressly authorized to comply with and obey orders, judgments or
decrees of any court. In case the Escrow Agent obeys or complies with any such
order, judgment or decree, the Escrow Agent shall not be liable to any of the
parties hereto or to any other person, firm or corporation by reason of such
decree being subsequently reversed, modified, annulled, set aside, vacated or
found to have been entered without jurisdiction.

                  3.10. The Escrow Agent shall not be liable in any respect on
account of the identity, authorization or rights of the parties executing or

counsel and other experts as the Escrow Agent may deem necessary properly to
advise the Escrow Agent in connection with the Escrow Agent's duties hereunder,

compensation therefor. THE ESCROW AGENT HAS ACTED AS LEGAL COUNSEL FOR THE
PURCHASER, AND MAY CONTINUE TO ACT AS LEGAL COUNSEL FOR THE PURCHASER, FROM TIME
TO TIME, NOTWITHSTANDING ITS DUTIES AS THE ESCROW AGENT HEREUNDER. THE COMPANY
CONSENTS TO THE ESCROW AGENT IN SUCH CAPACITY AS LEGAL COUNSEL FOR THE PURCHASER
AND WAIVES ANY CLAIM THAT SUCH REPRESENTATION REPRESENTS A CONFLICT OF INTEREST
ON THE PART OF THE ESCROW AGENT. THE COMPANY UNDERSTANDS THAT THE PURCHASER AND
THE ESCROW AGENT ARE RELYING EXPLICITLY ON THE FOREGOING PROVISION IN ENTERING
INTO THIS ESCROW AGREEMENT.

                  3.12. The Escrow Agent's responsibilities as escrow agent
hereunder shall terminate if the Escrow Agent shall resign by written notice to

Purchaser and the Company shall appoint a successor Escrow Agent.

                  3.13. If the Escrow Agent reasonably requires other or further
instruments in connection with this Escrow Agreement or obligations in respect
hereto, the necessary parties hereto shall join in furnishing such instruments.

arise with respect to the delivery and/or ownership or right of possession of
the documents or the escrow funds held by the Escrow Agent hereunder, the Escrow
Agent is authorized and directed in the Escrow Agent's sole discretion (1) to
retain in the Escrow Agent's possession without liability to anyone all or any
part of said documents or the escrow funds until such disputes shall have been
settled either by mutual written agreement of the parties concerned by a final
order, decree or judgment of a court of competent jurisdiction after the time
for appeal has expired and no appeal has been perfected, but the Escrow Agent
shall be under no duty whatsoever to institute or defend any such proceedings or
(2) to deliver the escrow funds and any other property and documents held by the
Escrow Agent hereunder to a state or Federal court having competent subject
matter jurisdiction and located in the State and City of New York in accordance
with the applicable procedure therefor.

                  3.15. The Company and the Purchaser agree jointly and
severally to indemnify and hold harmless the Escrow Agent and its partners,
employees, agents and representatives from any and all claims, liabilities,
costs or expenses in any way arising from or relating to the duties or
performance of the Escrow Agent hereunder or the transactions contemplated
hereby or by the Purchase Agreement other than any such claim, liability, cost
or expense to the extent the same shall have been determined by final,
unappealable judgment of a court of competent jurisdiction to have resulted from
the gross negligence or willful misconduct of the Escrow Agent.

                          REGISTRATION RIGHTS AGREEMENT

                  THIS REGISTRATION RIGHTS AGREEMENT, dated as of March 27, 2001
between Ironhead Investments Inc. ("Purchaser") and MigraTEC, Inc. (the
"Company").

                  WHEREAS, simultaneously with the execution and delivery of
this Agreement, the parties shall enter into the Common Stock Purchase
Agreement, dated as of the date hereof, (the "Purchase Agreement") pursuant to
which the Purchaser has committed to purchase up to $20,000,000 of the Company's
Common Stock (terms not defined herein shall have the meanings ascribed to them
in the Purchase Agreement) and the Warrant; and

                  WHEREAS, the execution and delivery of this Agreement and
granting to the Purchaser of the registration rights set forth herein with
respect to the Shares is a component part of the transaction contemplated under
the Purchase Agreement.

                  NOW, THEREFORE, the parties hereto mutually agree as follows:

                  Section 1. Registrable Securities. As used herein the term
"Registrable Security" means all Shares that (i) have not been sold under the
Registration Statement, (ii) have not been sold under circumstances under which
all of the applicable conditions of Rule 144 (or any similar provision then in
force) under the Securities Act ("Rule 144") are met, (iii) have not been
otherwise transferred to persons who may trade such Shares without restriction
under the Securities Act, and the Company has delivered a new certificate or
other evidence of ownership for such Shares not bearing a restrictive legend, or
(iv) may not be sold without any time, volume or manner limitations pursuant to
Rule 144(k) (or any similar provision then in effect) under the Securities Act.
In the event of any merger, reorganization, consolidation, recapitalization or
other change in corporate structure affecting the Common Stock, such adjustment
shall be deemed to be made in the definition of "Registrable Security" as is
appropriate in order to prevent any dilution or enlargement of the rights
granted pursuant to this Agreement.

                  Restrictions on Transfer. The Purchaser acknowledges and
understands that in the absence of an effective Registration Statement
authorizing the resale of the Shares as provided herein, the Shares are
"restricted securities" as defined in Rule 144. The Purchaser understands that
no disposition or transfer of the Shares may be made by Purchaser in the absence
of (i) an opinion of counsel to the Purchaser, in form and substance reasonably
satisfactory to the Company, that such transfer may be made without registration
under the Securities Act or (ii) such registration.

                  With a view to making available to the Purchaser the benefits
of Rule 144, the Company agrees to:

                        (a) comply with the provisions of paragraph (c)(1) of
         Rule 144; and

<PAGE>   2

                        (b) file with the Commission in a timely manner all
         reports and other documents required to be filed by the Company
         pursuant to Section 13 or 15(d) under the Exchange Act; and, if at any
         time it is not required to file such reports but in the past had been
         required to or did file such reports, it will, upon the request of the
         Purchaser, make available other information as required by, and so long
         as necessary to permit sales of, its Registrable Securities pursuant to
         Rule 144.

                  Section 3. Registration Rights With Respect to the Shares.

                        (a) The Company agrees that it will prepare and file
         with the Securities and Exchange Commission ("Commission"), within
         forty-five (45) days after the date hereof, a registration statement
         (on Form S-3 and/or S-1, or other appropriate form of registration
         statement) under the Securities Act (the "Registration Statement"), at
         the sole expense of the Company (except as provided in Section 3(c)
         hereof), so as to permit a public offering and resale of the Shares
         under the Securities Act by Purchaser.

                        (b) The Company shall cause the Registration Statement
         to become effective within the earlier of (i) ninety (90) days of the
         date of filing the Registration Statement, or (ii) five (5) days after
         receiving written notice of SEC clearance and will within said five (5)
         days request acceleration of effectiveness. The Company will notify
         Purchaser of the effectiveness of the Registration Statement within one
         Trading Day of such event.

                        (c) The Company will maintain the Registration Statement
         or post-effective amendment filed under this Section 3 hereof effective
         under the Securities Act until the earliest of (i) the date that all
         the Shares have been disposed of pursuant to the Registration
         Statement, (ii) the date that all of the Shares have been sold pursuant
         to the Registration Statement, (iii) the date that all Shares have been
         otherwise transferred to persons who may trade such shares without
         restriction under the Securities Act, and the Company has delivered a
         new certificate or other evidence of ownership for such Shares not
         bearing a restrictive legend, or (iv) the date that all Shares may be
         sold without any time, volume or manner limitations pursuant to Rule
         144(k) or any similar provision then in effect under the Securities Act
         in the opinion of counsel to the Company, which counsel shall be
         reasonably acceptable to the Purchaser (the "Effectiveness Period").

                        (d) All fees, disbursements and out-of-pocket expenses
         and costs incurred by the Company in connection with the preparation
         and filing of the Registration Statement under subparagraph 3(a) and in
         complying with applicable securities and Blue Sky laws (including,
         without limitation, all attorneys' fees of the Company) shall be borne
         by the Company. The Purchaser shall bear the cost of underwriting
         and/or brokerage discounts, fees and commissions, if any, applicable to
         the Shares being registered and the fees and expenses of its counsel.

                        (e) The Purchaser and its counsel shall have a
         reasonable period, not to exceed ten (10) Trading Days, to review the
         proposed Registration Statement or any amendment thereto, prior to
         filing with the Commission, and the Company shall provide

                                       2
<PAGE>   3

         the Purchaser with copies of any comment letters received from the
         Commission with respect thereto within two (2) Trading Days of receipt
         thereof.

                        (f) The Company shall make reasonably available for
         inspection by Purchaser, any underwriter participating in any
         disposition pursuant to the Registration Statement, and any attorney,
         accountant or other agent retained by the Purchaser or any such
         underwriter all relevant financial and other records, pertinent
         corporate documents and properties of the Company and its subsidiaries,
         and cause the Company's officers, directors and employees to supply all
         information reasonably requested by the Purchaser or any such
         underwriter, attorney, accountant or agent in connection with the
         Registration Statement, in each case, as is customary for due diligence
         examinations; provided, however, all records, information and documents
         that are designated in writing by the Company, in good faith, as
         confidential, proprietary or containing any material non-public
         information shall be kept confidential by the Purchaser and any such
         underwriter, attorney, accountant or agent, unless such disclosure is
         made pursuant to judicial process in a court proceeding (after first
         giving the Company an opportunity promptly to seek a protective order
         or otherwise limit the scope of the information sought to be disclosed)
         or is required by law, or such records, information or documents become
         available to the public generally or through a third party not in
         violation of an accompanying obligation of confidentiality. If the
         foregoing inspection and information gathering would otherwise disrupt
         the Company's conduct of its business, such inspection and information
         gathering shall, to the maximum extent possible, be coordinated on
         behalf of the Purchaser and the other parties entitled thereto by one
         firm of counsel designed by and on behalf of the majority in interest
         of Purchaser and other parties.

                        (g) The Company shall qualify any of the Shares for sale
         in such states as the Purchaser reasonably designates and shall furnish
         indemnification in the manner provided in Section 6 hereof. However,
         the Company shall not be required to qualify in any state which will
         require an escrow or other restriction relating to the Company and/or
         the sellers, or which will require the Company to qualify to do
         business in such state or require the Company to file therein any
         general consent to service of process.

                        (h) The Company at its expense will supply the Purchaser
         with copies of the Registration Statement and the final prospectus
         included therein (the "Prospectus") and other related documents in such
         quantities as may be reasonably requested by the Purchaser.

                        (i) The Company shall not be required by this Section 3
         to include the Purchaser's Shares in any Registration Statement which
         is to be filed if, in the opinion of counsel for both the Purchaser and
         the Company (or, should they not agree, in the opinion of another
         counsel experienced in securities law matters acceptable to counsel for
         the Purchaser and the Company) the proposed offering or other transfer
         as to which such registration is requested is exempt from applicable
         federal and state securities laws and would result in all purchasers or
         transferees obtaining securities which are not "restricted securities",
         as defined in Rule 144 under the Securities Act.

                                       3

                        (j) If at any time or from time to time after the
         effective date of the Registration Statement, the Company notifies the
         Purchaser in writing of the existence of a Potential Material Event (as
         defined in Section 3(k) below), the Purchaser shall not offer or sell
         any Shares or engage in any other transaction involving or relating to
         Shares, from the time of the giving of notice with respect to a
         Potential Material Event until the Purchaser receives written notice
         from the Company that such Potential Material Event either has been
         disclosed to the public or no longer constitutes a Potential Material
         Event (the "Suspension Period"). Notwithstanding anything herein to the
         contrary, if a Suspension Period occurs at any time during any period
         commencing on a Trading Day a Draw Down Notice is deemed delivered and
         ending ten (10) Trading Days following the end of the corresponding
         Draw Down Pricing Period, then the Company must compensate the
         Purchaser for any net decline in the market value of any Shares
         purchased, or committed to be purchased, by the Purchaser pursuant to
         such recent Draw Down Pricing Period through the end of such Suspension
         Period. Net decline shall be calculated as the difference between the
         highest VWAP during the applicable Suspension Period and the VWAP on
         the Trading Day immediately following a properly delivered notice to
         the Purchaser that such Suspension Period has ended. If a Potential
         Material Event shall occur prior to the date the Registration Statement
         is filed, then the Company's obligation to file the Registration
         Statement shall be delayed without penalty for not more than thirty
         (30) calendar days. THE COMPANY MUST GIVE PURCHASER NOTICE IN WRITING
         OF THE EXISTENCE OF A POTENTIAL MATERIAL EVENT PROMPTLY UPON KNOWLEDGE
         THAT SUCH AN EVENT EXISTS AND, WHERE POSSIBLE, AT LEAST TWO (2) DAYS
         PRIOR TO THE FIRST DAY OF A SUSPENSION PERIOD, IF LAWFUL TO DO SO.

                        (k) "Potential Material Event" means any of the
         following: (i) the possession by the Company of material information
         that is not ripe for disclosure in a registration statement, as
         determined in good faith by the Chief Executive Officer or the Board of
         Directors of the Company or that disclosure of such information in the
         Registration Statement would be detrimental to the business and affairs
         of the Company; (ii) any material engagement or activity by the Company
         which would, in the good faith determination of the Chief Executive
         Officer or the Board of Directors of the Company, be adversely affected
         by disclosure in a registration statement at such time, which
         determination shall be accompanied by a good faith determination by the
         Chief Executive Officer or the Board of Directors of the Company that
         the Registration Statement would be materially misleading absent the
         inclusion of such information, or (iii) pursuant to applicable law, the
         Company is required to file a post-effective amendment to the
         Registration Statement because the Company experiences a fundamental
         change, must change the plan of distribution to the Prospectus, or must
         update the information included in the Prospectus pursuant to Section
         10(a)(3) of the Securities Act.

                  Section 4. Cooperation with Company. The Purchaser will
cooperate with the Company in all respects in connection with this Agreement,
including timely supplying all information reasonably requested by the Company
(which shall include all information regarding the Purchaser and proposed manner
of sale of the Registrable Securities required to be disclosed in the
Registration Statement) and executing and returning all documents reasonably
requested in connection with the registration and sale of the Registrable
Securities and entering into and

                                       4
<PAGE>   5
performing its obligations under any underwriting agreement, if the offering is
an underwritten offering, in usual and customary form, with the managing
underwriter or underwriters of such underwritten offering. The Purchaser shall
consent to be named as an underwriter in the Registration Statement. Purchaser
acknowledges that in accordance with current Commission policy, the Purchaser
will be named as the underwriter of the Shares in the Registration Statement.

                  Section 5. Registration Procedures. If and whenever the
Company is required by any of the provisions of this Agreement to effect the
registration of any of the Registrable Securities under the Securities Act, the
Company shall (except as otherwise provided in this Agreement), as expeditiously
as possible, subject to the Purchaser's assistance and cooperation as reasonably
required:

                        (a) prepare and file with the Commission such amendments
         and supplements to the Registration Statement and the Prospectus as may
         be necessary to keep such registration statement effective and to
         comply with the provisions of the Securities Act with respect to the
         sale or other disposition of all securities covered by such
         registration statement whenever the Purchaser of such Registrable
         Securities shall desire to sell or otherwise dispose of the same
         (including prospectus supplements with respect to the sales of
         securities from time to time in connection with a registration
         statement pursuant to Rule 415 promulgated under the Securities Act)
         and (ii) take all lawful action such that each of (A) the Registration
         Statement and any amendment thereto does not, when it becomes
         effective, contain an untrue statement of a material fact or omit to
         state a material fact required to be stated therein or necessary to
         make the statements therein not misleading and (B) the Prospectus, and
         any amendment or supplement thereto, does not at any time during the
         Effectiveness Period include an untrue statement of a material fact or
         omit to state a material fact required to be stated therein or
         necessary to make the statements therein, in light of the circumstances
         under which they were made, not misleading;

                        (b) prior to the filing with the Commission of any
         Registration Statement (including any amendments thereto) and the
         distribution or delivery of the Prospectus (including any supplements
         thereto), provide draft copies thereof to the Purchaser and reflect in
         such documents all such comments as the Purchaser (and its counsel)
         reasonably may propose and (ii) furnish to the Purchaser such numbers
         of copies of the Prospectus including a preliminary prospectus or any
         amendment or supplement to the Prospectus, as applicable, in conformity
         with the requirements of the Securities Act, and such other documents,
         as the Purchaser may reasonably request in order to facilitate the
         public sale or other disposition of the Registrable Securities;

                        (c) comply with the New York blue sky laws with respect
         to the Registrable Securities (subject to the limitations set forth in
         Section 3(g) above), and do any and all other acts and things which may
         be reasonably necessary or advisable to enable the Purchaser to
         consummate the public sale or other disposition in such jurisdiction of
         the Registrable Securities;

                                       5
<PAGE>   6

                        (d) list such Registrable Securities on the Principal
         Market, and any other exchange on which the Common Stock of the Company
         is then listed, if the listing of such Registrable Securities is then
         permitted under the rules of such exchange or the Nasdaq Stock Market;

                        (e) notify the Purchaser at any time when the Prospectus
         is required to be delivered under the Securities Act, of the happening
         of any event of which it has knowledge as a result of which the
         Prospectus, as then in effect, includes an untrue statement of a
         material fact or omits to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading in
         the light of the circumstances then existing, and the Company shall
         prepare and file a curative amendment or curative supplement under
         Section 5(a) as quickly as commercially possible and the period
         beginning on the date of notice until the curative amendment is
         effective or a curative supplement is filed shall be deemed a
         Suspension Period and the Company shall compensate the Purchaser as set
         forth in Section 3(j) herein;

                        (f) as promptly as practicable after becoming aware of
         such event, notify the Purchaser (or, in the event of an underwritten
         offering, the managing underwriters) of the issuance by the Commission
         or any state authority of any stop order or other suspension of the
         effectiveness of the Registration Statement at the earliest possible
         time and take all lawful action to effect the withdrawal, rescission or
         removal of such stop order or other suspension;

                        (g) take all such other lawful actions reasonably
         necessary to expedite and facilitate the disposition by the Purchaser
         of its Registrable Securities in accordance with the intended methods
         therefor provided in the Prospectus which are customary for issuers to
         perform under the circumstances;

                        (h) in the event of an underwritten offering, promptly
         include or incorporate in a prospectus supplement or post-effective
         amendment to the Registration Statement such information as the
         managing underwriters reasonably agree should be included therein and
         to which the Company does not reasonably object and make all required
         filings of such prospectus supplement or post-effective amendment as
         soon as practicable after it is notified of the matters to be included
         or incorporated in such prospectus supplement or post-effective
         amendment; and

                        (i) maintain a transfer agent for its Common Stock.

                  Section 6. Indemnification.

                        (a) The Company agrees to indemnify and hold harmless
         the Purchaser and each person, if any, who controls the Purchaser
         within the meaning of the Securities Act ("Distributing Purchaser")
         against any losses, claims, damages or liabilities, joint or several
         (which shall, for all purposes of this Agreement, include, but not be
         limited to, all reasonable costs of defense and investigation and all
         reasonable attorneys' fees), to which the Distributing Purchaser may
         become subject, under the Securities Act or otherwise,

                                       6
<PAGE>   7
         insofar as such losses, claims, damages or liabilities (or actions in
         respect thereof) arise out of or are based upon any untrue statement or
         alleged untrue statement of any material fact contained in the
         Registration Statement, or any related preliminary prospectus, the
         Prospectus or amendment or supplement thereto, or arise out of or are
         based upon the omission or alleged omission to state therein a material
         fact required to be stated therein or necessary to make the statements
         therein not misleading; provided, however, that the Company will not be
         liable in any such case to the extent that any such loss, claim, damage
         or liability arises out of or is based upon an untrue statement or
         alleged untrue statement or omission or alleged omission made in the
         Registration Statement, preliminary prospectus, the Prospectus or
         amendment or supplement thereto in reliance upon, and in conformity
         with, written information furnished to the Company by the Distributing
         Purchaser specifically for use in the preparation thereof. This Section
         6(a) shall not inure to the benefit of any Distributing Purchaser with
         respect to any person asserting such loss, claim, damage or liability
         who purchased the Registrable Securities which are the subject thereof
         if the Distributing Purchaser failed to send or give a copy of the
         Prospectus to such person at or prior to the written confirmation to
         such person of the sale of such Registrable Securities, where the
         Distributing Purchaser was obligated to do so under the Securities Act
         or the rules and regulations promulgated thereunder. This indemnity
         agreement will be in addition to any liability which the Company may
         otherwise have.

                        (b) Each Distributing Purchaser agrees that it will
         indemnify and hold harmless the Company, and each officer, director of
         the Company or person, if any, who controls the Company within the
         meaning of the Securities Act, against any losses, claims, damages or
         liabilities (which shall, for all purposes of this Agreement, include,
         but not be limited to, all reasonable costs of defense and
         investigation and all reasonable attorneys' fees) to which the Company
         or any such officer, director or controlling person may become subject
         under the Securities Act or otherwise, insofar as such losses, claims,
         damages or liabilities (or actions in respect thereof) arise out of or
         are based upon any untrue statement or alleged untrue statement of any
         material fact contained in the Registration Statement, or any related
         preliminary prospectus, the Prospectus or amendment or supplement
         thereto, or arise out of or are based upon the omission or the alleged
         omission to state therein a material fact required to be stated therein
         or necessary to make the statements therein not misleading, but in each
         case only to the extent that such untrue statement or alleged untrue
         statement or omission or alleged omission was made in the Registration
         Statement, preliminary prospectus, the Prospectus or amendment or
         supplement thereto in reliance upon, and in conformity with, written
         information furnished to the Company by such Distributing Purchaser
         specifically for use in the preparation thereof. This indemnity
         agreement will be in addition to any liability which the Distributing
         Purchaser may otherwise have. Notwithstanding anything to the contrary
         herein, the Distributing Purchaser shall not be liable under this
         Section 6(b) for any amount in excess of the net proceeds to such
         Distributing Purchaser as a result of the sale of Registrable
         Securities pursuant to the Registration Statement.

                        (c) Promptly after receipt by an indemnified party under
         this Section 6 of notice of the commencement of any action, such
         indemnified party will, if a claim in

                                       7
<PAGE>   8
         respect thereof is to be made against the indemnifying party under this
         Section 6, notify the indemnifying party of the commencement thereof;
         but the omission so to notify the indemnifying party will not relieve
         the indemnifying party from any liability which it may have to any
         indemnified party except to the extent of actual prejudice demonstrated
         by the indemnifying party. In case any such action is brought against
         any indemnified party, and it notifies the indemnifying party of the
         commencement thereof, the indemnifying party will be entitled to
         participate in, and, to the extent that it may wish, jointly with any
         other indemnifying party similarly notified, assume the defense
         thereof, subject to the provisions herein stated and after notice from
         the indemnifying party to such indemnified party of its election so to
         assume the defense thereof, the indemnifying party will not be liable
         to such indemnified party under this Section 6 for any legal or other
         expenses subsequently incurred by such indemnified party in connection
         with the defense thereof other than reasonable costs of investigation,
         unless the indemnifying party shall not pursue the action to its final
         conclusion. The indemnified party shall have the right to employ
         separate counsel in any such action and to participate in the defense
         thereof, but the fees and expenses of such counsel shall not be at the
         expense of the indemnifying party if the indemnifying party has assumed
         the defense of the action with counsel reasonably satisfactory to the
         indemnified party; provided that if the indemnified party is the
         Distributing Purchaser, the fees and expenses of such counsel shall be
         at the expense of the indemnifying party if (i) the employment of such
         counsel has been specifically authorized in writing by the indemnifying
         party, or (ii) the named parties to any such action (including any
         impleaded parties) include both the Distributing Purchaser and the
         indemnifying party and the Distributing Purchaser shall have been
         advised by such counsel that there may be one or more legal defenses
         available to the indemnifying party different from or in conflict with
         any legal defenses which may be available to the Distributing Purchaser
         (in which case the indemnifying party shall not have the right to
         assume the defense of such action on behalf of the Distributing
         Purchaser, it being understood, however, that the indemnifying party
         shall, in connection with any one such action or separate but
         substantially similar or related actions in the same jurisdiction
         arising out of the same general allegations or circumstances, be liable
         only for the reasonable fees and expenses of one separate firm of
         attorneys for the Distributing Purchaser, which firm shall be
         designated in writing by the Distributing Purchaser and be approved by
         the indemnifying party). No settlement of any action against an
         indemnified party shall be made without the prior written consent of
         the indemnified party, which consent shall not be unreasonably
         withheld.

                  All fees and expenses of the indemnified party (including
         reasonable costs of defense and investigation in a manner not
         inconsistent with this Section and all reasonable attorneys' fees and
         expenses) shall be paid to the indemnified party, as incurred, within
         ten (10) Trading Days of written notice thereof to the indemnifying
         party; provided, that the indemnifying party may require such
         indemnified party to undertake to reimburse all such fees and expenses
         to the extent it is finally judicially determined that such indemnified
         party is not entitled to indemnification hereunder.

                  Section 7. Contribution. In order to provide for just and
equitable contribution under the Securities Act in any case in which (i) the
indemnified party makes a claim for

                                       8
<PAGE>   9
indemnification pursuant to Section 6 hereof but is judicially determined (by
the entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that the express provisions of Section 6 hereof provide for indemnification in
such case, or (ii) contribution under the Securities Act may be required on the
part of any indemnified party, then the Company and the applicable Distributing
Purchaser shall contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (which shall, for all purposes of this
Agreement, include, but not be limited to, all reasonable costs of defense and
investigation and all reasonable attorneys' fees), in either such case (after
contribution from others) on the basis of relative fault as well as any other
relevant equitable considerations. The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company on the one hand or the applicable
Distributing Purchaser on the other hand, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and the Distributing Purchaser agree that it
would not be just and equitable if contribution pursuant to this Section 7 were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in this
Section 7. The amount paid or payable by an indemnified party as a result of the
losses, claims, damages or liabilities (or actions in respect thereof) referred
to above in this Section 7 shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

                       Notwithstanding any other provision of this Section 7, in
no event shall any (i) Purchaser be required to undertake liability to any
person under this Section 7 for any amounts in excess of the dollar amount of
the net proceeds to be received by the Purchaser from the sale of the
Purchaser's Registrable Securities (after deducting any fees, discounts and
commissions applicable thereto) pursuant to any Registration Statement under
which such Registrable Securities are or were to be registered under the
Securities Act and (ii) underwriter be required to undertake liability to any
person hereunder for any amounts in excess of the aggregate discount, commission
or other compensation payable to such underwriter with respect to the
Registrable Securities underwritten by it and distributed pursuant to the
Registration Statement.

                  Section 8. Notices. All notices, demands, requests, consents,
approvals, and other communications required or permitted hereunder shall be in
writing and, unless otherwise specified herein, shall be delivered as set forth
in the Purchase Agreement.

                  Section 9. Assignment. Neither this Agreement nor any rights
of the Purchaser or the Company hereunder may be assigned by either party to any
other person. Notwithstanding the foregoing, (a) the provisions of this
Agreement shall inure to the benefit of, and be enforceable by, any transferee
of any of the Common Stock purchased by the Purchaser pursuant to the Purchase
Agreement other than through open-market sales, and (b) upon the prior written
consent of the Company, which consent shall not be unreasonably withheld or
delayed in the case

                                       9
<PAGE>   10
of an assignment to an affiliate of the Purchaser, the Purchaser's interest in
this Agreement may be assigned at any time, in whole or in part, to any other
person or entity (including any affiliate of the Purchaser) who agrees to be
bound hereby.

                  Section 10. Counterparts/Facsimile. This Agreement may be
executed in two or more counterparts, each of which shall constitute an
original, but all of which, when together shall constitute but one and the same
instrument, and shall become effective when one or more counterparts have been
signed by each party hereto and delivered to the other party. In lieu of the
original, a facsimile transmission or copy of the original shall be as effective
and enforceable as the original.

                  Section 11. Remedies and Severability. The remedies provided
in this Agreement are cumulative and not exclusive of any remedies provided by
law. If any term, provision, covenant or restriction of this Agreement is held
by a board of arbitration or a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such
term, provision, covenant or restriction. It is hereby stipulated and declared
to be the intention of the parties that they would have executed the remaining
terms, provisions, covenants and restrictions without including any of those
that may be hereafter declared invalid, illegal, void or unenforceable.

                  Section 12. Conflicting Agreements. The Company shall not
enter into any agreement with respect to its securities that is inconsistent
with the rights granted to the purchasers of Registrable Securities in this
Agreement or otherwise prevents the Company from complying with all of its
obligations hereunder.

                  Section 13. Headings. The headings in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

                  Section 14. Governing Law. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York applicable to
contracts made in New York by persons domiciled in New York City and without
regard to its principles of conflicts of laws. Any action may be brought as set
forth in the Purchase Agreement. The Company and the Purchaser agree to submit
themselves to the in personam jurisdiction of the state and federal courts
situated within the Southern District of the State of New York with regard to
any controversy arising out of or relating to this Agreement. Any party shall
have the right to seek injunctive relief from any court of competent
jurisdiction in any case where such relief is available. Any dispute under this
Agreement shall be submitted to arbitration under the American Arbitration
Association (the "AAA") in New York City, New York, and shall be finally and
conclusively determined by the decision of a board of arbitration consisting of
three (3) members (hereinafter referred to as the "Board of Arbitration")
selected as according to the rules governing the AAA. The Board of Arbitration
shall meet on consecutive business days in New York City, New York, and shall
reach and render a decision in writing (concurred in by a majority of the
members of the Board of Arbitration) with respect to the amount, if any, which
the losing party is required to pay to

the other party in respect of a claim filed. In connection with rendering its
decisions, the Board of Arbitration shall adopt and follow the laws of the State
of New York. To the extent practical, decisions of the Board of Arbitration
shall be rendered no more than thirty (30) calendar days following commencement
of proceedings with respect thereto. The Board of Arbitration shall cause its
written decision to be delivered to all parties involved in the dispute. The
Board of Arbitration shall be authorized and is directed to enter a default
judgment against any party refusing to participate in the arbitration proceeding
within thirty days of any deadline for such participation. Any decision made by
the Board of Arbitration (either prior to or after the expiration of such thirty
(30) calendar day period) shall be final, binding and conclusive on the parties
to the dispute, and entitled to be enforced to the fullest extent permitted by
law and entered in any court of competent jurisdiction. The prevailing party
shall be awarded its costs, including attorneys' fees, from the non-prevailing
party as part of the arbitration award. Any party shall have the right to seek
injunctive relief from any court of competent jurisdiction in any case where
such relief is available. The prevailing party in such injunctive action shall
be awarded its costs, including attorney's fees, from the non-prevailing party.
