     2.   SHELF REGISTRATION

                                     -3-



          (a)  On or prior to the Filing Date, the Company shall prepare and 
file with the Commission a "Shelf" Registration Statement covering all 
Registrable Securities for an offering to be made on a continuous basis 
pursuant to Rule 415.  The Registration Statement shall be on Form S-3 (or if 
the Company is not then eligible to register for resale the Registrable 
Securities on Form S-3 such registration shall be on another appropriate form 
in accordance herewith, or, in connection with an Underwritten Offering 
hereunder, such other form agreed to by the Company and by the Holders of 
Registrable Securities). The Company shall use its best efforts to cause the 
Registration Statement to be declared effective under the Securities Act as 
promptly as possible after the filing thereof, but in any event prior to the 
Effectiveness Date, and shall use its best efforts to keep such Registration 
Statement continuously effective under the Securities Act until the date which 
is three years after the date that such Registration Statement is declared 
effective by the Commission or such earlier date when all Registrable 
Securities covered by such Registration Statement have been sold or may be 
sold without volume restrictions pursuant to Rule 144(k) (the "EFFECTIVENESS 
PERIOD"), PROVIDED, HOWEVER, that the Company shall not be deemed to have used 
its best efforts to keep the Registration Statement effective during the 
Effectiveness Period if it voluntarily takes any action that would result in 
the Holders not being able to sell the Registrable Securities covered by such 
Registration Statement during the Effectiveness Period, unless such action is 
required under applicable law or the Company has filed a post-effective 
amendment to the Registration Statement and the Commission has not declared it 
effective.

          (b)  If the Holders of a majority of the Registrable Securities so 
elect, an offering of Registrable Securities pursuant to the Registration 
Statement may be effected in the form of an Underwritten Offering.  In such 
event, and, if the managing underwriters advise the Company and such Holders 
in writing that in their opinion the amount of Registrable Securities proposed 
to be sold in such Underwritten Offering exceeds the amount of Registrable 
Securities which can be sold in such Underwritten Offering, there shall be 
included in such Underwritten Offering the amount of such Registrable 
Securities which in the opinion of such managing underwriters can be sold, and 
such amount shall be allocated pro rata among the Holders proposing to sell 
Registrable Securities in such Underwritten Offering.

          (c)  If any of the Registrable Securities are to be sold in an 
Underwritten Offering, the investment banker in interest that will administer 
the offering will be selected by the Holders of a majority of the Registrable 
Securities included in such offering upon consultation with the Company.  No 
Holder may participate in any Underwritten Offering hereunder unless such 
Holder (i) agrees to sell its Registrable Securities on the basis provided in 
any underwriting agreements approved by the Persons entitled hereunder to 
approve such arrangements and (ii) completes and executes all questionnaires, 
powers of attorney, indemnities, underwriting agreements and other documents 
required under the terms of such arrangements.

     3.   REGISTRATION PROCEDURES

          In connection with the Company's registration obligations hereunder,

          (a)  Prepare and file with the Commission on or prior to the Filing 
Date, a Registration Statement on Form S-3 (or if the Company is not then 
eligible to register for resale the Registrable Securities on Form S-3 such 
registration shall be on another appropriate form in accordance herewith, or, 
in connection with an Underwritten Offering hereunder, such other form agreed 
to by the Company and by the Holders of Registrable Securities) which shall 
contain the "Plan of Distribution" attached hereto as ANNEX A  (except if 
otherwise directed by the Holders), and cause the Registration Statement to 
become effective and remain effective as provided herein; PROVIDED, HOWEVER, 
that not less than five (5) Business Days prior to the filing of the initial 
Registration Statement or not less than two (2) Business Days prior to the 
filing of any related Prospectus or any amendment or supplement thereto 
(including any document that would be incorporated or deemed to be 
incorporated therein by reference), the Company shall, (i) furnish to the 
Holders, their Special Counsel and any managing underwriters, copies of all 
such documents proposed to be filed, which documents (other than those 
incorporated or deemed to be incorporated by reference) will be subject to the 
review of such Holders, their Special Counsel and such managing underwriters, 
and (ii) cause its officers and directors, counsel and independent certified 
public accountants to respond to such inquiries as shall be necessary, in the 
reasonable opinion of respective counsel to such Holders and such 
underwriters, to conduct a reasonable investigation within the meaning of the 
Securities Act.  The Company shall not file the Registration Statement or any 
such Prospectus or any amendments or supplements thereto to which the Holders 
of a majority of the Registrable Securities, their Special Counsel, or any 
managing underwriters, shall reasonably object on a timely basis.

          (b)  (i)  Prepare and file with the Commission such amendments, 
including post-effective amendments, to the Registration Statement as may be 
necessary to keep the Registration Statement continuously effective as to the 
applicable Registrable Securities for the Effectiveness Period and prepare and 
file with the Commission such additional Registration Statements in order to 
register for resale under the Securities Act all of the Registrable 
Securities; (ii) cause the related Prospectus to be amended or supplemented by 
any required Prospectus supplement, and as so supplemented or amended to be 
filed pursuant to Rule 424 (or any similar provisions then in force) 
promulgated under the Securities Act; (iii) respond as promptly as reasonably 
possible to any comments received from the Commission with respect to the 
Registration Statement or any amendment thereto and as promptly as reasonably 
possible provide the Holders true and complete copies of all correspondence 
from and to the Commission relating to the Registration Statement; and (iv) 
comply in all material respects with the provisions of the Securities Act and 
the Exchange Act with respect to the disposition of all Registrable Securities 
covered by the Registration Statement during the applicable period in 
accordance with the intended methods of disposition by the Holders thereof set 
forth in the Registration Statement as so amended or in such Prospectus as so 
supplemented.

          (c)  Notify the Holders of Registrable Securities to be sold, their 
Special Counsel and any managing underwriters as promptly as reasonably 
possible (and, in the case of (i)(A) below, not less than five (5) days prior 
to such filing) and (if requested by any such Person) confirm such notice in 
writing no later than one (1) Business Day following the day (i)(A) when a 
Prospectus or any Prospectus supplement or post-effective amendment to the 
Registration Statement is proposed to be filed; (B) when the Commission 
notifies the Company whether there will be a "review" of such 

                                     -5-



Registration Statement and whenever the Commission comments in writing on such 
Registration Statement (the Company shall provide true and complete copies 
thereof and all written responses thereto to each of the Holders); and (C) 
with respect to the Registration Statement or any post-effective amendment, 
when the same has become effective; (ii) of any request by the Commission or 
any other Federal or state governmental authority for amendments or 
supplements to the Registration Statement or Prospectus or for additional 
information; (iii) of the issuance by the Commission of any stop order 
suspending the effectiveness of the Registration Statement covering any or all 
of the Registrable Securities or the initiation of any Proceedings for that 
purpose; (iv) if at any time any of the representations and warranties of the 
Company contained in any agreement (including any underwriting agreement) 
contemplated hereby ceases to be true and correct in all material respects; 
(v) of the receipt by the Company of any notification with respect to the 
suspension of the qualification or exemption from qualification of any of the 
Registrable Securities for sale in any jurisdiction, or the initiation or 
threatening of any Proceeding for such purpose; and (vi) of the occurrence of 
any event that makes any statement made in the Registration Statement or 
Prospectus or any document incorporated or deemed to be incorporated therein 
by reference untrue in any material respect or that requires any revisions to 
the Registration Statement, Prospectus or other documents so that, in the case 
of the Registration Statement or the Prospectus, as the case may be, it will 
not contain any untrue statement of a material fact or omit to state any 
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.

          (d)  Use its best efforts to avoid the issuance of, or, if issued, 
obtain the withdrawal of (i) any order suspending the effectiveness of the 
Registration Statement, or (ii) any suspension of the qualification (or 
exemption from qualification) of any of the Registrable Securities for sale in 
any jurisdiction, at the earliest practicable moment.

          (e)  If requested by any managing underwriter or the Holders of a 
majority in interest of the Registrable Securities to be sold in connection 
with an Underwritten Offering, (i) promptly incorporate in a Prospectus 
supplement or post-effective amendment to the Registration Statement such 
information as such managing underwriters and such Holders reasonably agree 
should be included therein, and (ii) make all required filings of such 
Prospectus supplement or such post-effective amendment as soon as practicable 
after the Company has received notification of the matters to be incorporated 
in such Prospectus supplement or post-effective amendment; PROVIDED, HOWEVER, 
that the Company shall not be required to take any action pursuant to this 
Section 3(e) that would, in the opinion of counsel for the Company, violate 
applicable law or be materially detrimental to the business prospects of the 
Company.

          (f)  Furnish to each Holder, their Special Counsel and any managing 
underwriters, without charge, at least one conformed copy of each Registration 
Statement and each amendment thereto, including financial statements and 
schedules, all documents incorporated or deemed to be incorporated therein by 
reference, and all exhibits to the extent requested by such Person (including 
those previously furnished or incorporated by reference) promptly after the 
filing of such documents with the Commission.

                                     -6-



          (g)  Promptly deliver to each Holder, their Special Counsel, and any 
underwriters, without charge, as many copies of the Prospectus or Prospectuses 
(including each form of prospectus) and each amendment or supplement thereto 
as such Persons may reasonably request; and the Company hereby consents to the 
use of such Prospectus and each amendment or supplement thereto by each of the 
selling Holders and any underwriters in connection with the offering and sale 
of the Registrable Securities covered by such Prospectus and any amendment or 
supplement thereto.

          (h)  Prior to any public offering of Registrable Securities, use its 
best efforts to register or qualify or cooperate with the selling Holders, any 
underwriters and their Special Counsel in connection with the registration or 
qualification (or exemption from such registration or qualification) of such 
Registrable Securities for offer and sale under the securities or Blue Sky 
laws of such jurisdictions within the United States as any Holder or 
underwriter requests in writing, to keep each such registration or 
qualification (or exemption therefrom) effective during the Effectiveness 
Period and to do any and all other acts or things necessary or advisable to 
enable the disposition in such jurisdictions of the Registrable Securities 
covered by a Registration Statement; PROVIDED, HOWEVER, that the Company shall 
not be required to qualify generally to do business in any jurisdiction where 
it is not then so qualified or to take any action that would subject it to 
general service of process in any such jurisdiction where it is not then so 
subject or subject the Company to any material tax in any such jurisdiction 
where it is not then so subject.

          (i)  Cooperate with the Holders and any managing underwriters to 
facilitate the timely preparation and delivery of certificates representing 
Registrable Securities to be delivered to a transferee pursuant to a 
Registration Statement, which certificates shall be free, to the extent 
permitted by applicable law, of all restrictive legends, and to enable such 
Registrable Securities to be in such denominations and registered in such 
names as any such managing underwriters or Holders may request at least two 
Business Days prior to any sale of Registrable Securities.

          (j)  Upon the occurrence of any event contemplated by Section 
3(c)(vi), as promptly as reasonably possible, prepare a supplement or 
amendment, including a post-effective amendment, to the Registration Statement 
or a supplement to the related Prospectus or any document incorporated or 
deemed to be incorporated therein by reference, and file any other required 
document so that, as thereafter delivered, neither the Registration Statement 
nor such Prospectus will 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, in light of the circumstances under which they 
were made, not misleading.

          (k)  Use its best efforts to cause all Registrable Securities 
relating to such Registration Statement to be listed on the Nasdaq National 
Market ("NASDAQ") or on any other stock market or trading facility on which 
the shares of Common Stock are traded, listed or quoted (each a "SUBSEQUENT 
MARKET") as and when required pursuant to the Purchase Agreement.

          (l)  Enter into such agreements (including an underwriting agreement 
in form, scope and substance as is customary in Underwritten Offerings) and 
take all such other actions in connection therewith (including those 
reasonably requested by any managing underwriters and the Holders of a 
majority of the Registrable Securities being sold) in order to expedite or 
facilitate the

                                     -7-




disposition of such Registrable Securities, and whether or not an underwriting 
agreement is entered into, (i) make such representations and warranties to 
such Holders and such underwriters as are customarily made by issuers to 
underwriters in underwritten public offerings, and confirm the same if and 
when requested; (ii) in the case of an Underwritten Offering obtain and 
deliver copies thereof to each Holder and the managing underwriters, if any, 
of opinions of counsel to the Company and updates thereof addressed to each 
Holder and each such underwriter, in form, scope and substance reasonably 
satisfactory to any such managing underwriters and Special Counsel to the 
selling Holders covering the matters customarily covered in opinions requested 
in Underwritten Offerings and such other matters as may be reasonably 
requested by such Special Counsel and underwriters; (iii) immediately prior to 
the effectiveness of the Registration Statement, and, in the case of an 
Underwritten Offering, at the time of delivery of any Registrable Securities 
sold pursuant thereto, use its best reasonable efforts to obtain and deliver 
copies to the Holders and the managing underwriters, if any, of "cold comfort" 
letters and updates thereof from the independent certified public accountants 
of the Company (and, if necessary, any other independent certified public 
accountants of any subsidiary of the Company or of any business acquired by 
the Company for which financial statements and financial data is, or is 
required to be, included in the Registration Statement), addressed to the 
Company in form and substance as are customary in connection with Underwritten 
Offerings; (iv) if an underwriting agreement is entered into, the same shall 
contain indemnification provisions and procedures no less favorable to the 
selling Holders and the underwriters, if any, than those set forth in Section 
5 (or such other provisions and procedures acceptable to the managing 
underwriters, if any, and holders of a majority of Registrable Securities 
participating in such Underwritten Offering); and (v) deliver such documents 
and certificates as may be reasonably requested by the Holders of a majority 
of the Registrable Securities being sold, their Special Counsel and any 
managing underwriters to evidence the continued validity of the 
representations and warranties made pursuant to clause 3(l)(i) above and to 
evidence compliance with any customary conditions contained in the 
underwriting agreement or other agreement entered into by the Company.

          (m)  Make available for inspection by the selling Holders, any 
representative of such Holders, any underwriter participating in any 
disposition of Registrable Securities, and any attorney or accountant retained 
by such selling Holders or underwriters, at the offices where normally kept, 
during reasonable business hours, all financial and other records, pertinent 
corporate documents and properties of the Company and its subsidiaries, and 
cause the officers, directors, agents and employees of the Company and its 
subsidiaries to supply all information in each case reasonably requested by 
any such Holder, representative, underwriter, attorney or accountant in 
connection with the Registration Statement; PROVIDED, HOWEVER, that any 
information that is determined in good faith by the Company in writing to be 
of a confidential nature at the time of delivery of such information shall be 
kept confidential by such Persons, unless (i) disclosure of such information 
is required by court or administrative order or is necessary to respond to 
inquiries of regulatory authorities; (ii) disclosure of such information, in 
the opinion of counsel to such Person, is required by law; (iii) such 
information becomes generally available to the public other than as a result 
of a disclosure or failure to safeguard by such Person; or (iv) such 
information becomes available to such Person from a source other than the 
Company and such source is not known by such Person to be bound by a 
confidentiality agreement with the Company.

          (n)  Comply with all applicable rules and regulations of the 
Commission.

                                     -8-



          (o)  The Company may require each selling Holder to furnish to the 
Company such information regarding the distribution of such Registrable 
Securities and the beneficial ownership of Common Stock held by such Holder as 
is required by law to be disclosed in the Registration Statement, and the 
Company may exclude from such registration the Registrable Securities of any 
such Holder who unreasonably fails to furnish such information within a 
reasonable time after receiving such request.

          If the Registration Statement refers to any Holder by name or 
otherwise as the holder of any securities of the Company, then such Holder 
shall have the right to require (if such reference to such Holder by name or 
otherwise is not required by the Securities Act or any similar Federal statute 
then in force) the deletion of the reference to such Holder in any amendment 
or supplement to the Registration Statement filed or prepared subsequent to 
the time that such reference ceases to be required.

          Each Holder covenants and agrees that (i) it will not sell any 
Registrable Securities under the Registration Statement until it has received 
copies of the Prospectus as then amended or supplemented as contemplated in 
Section 3(g) and notice from the Company that such Registration Statement and 
any post-effective amendments thereto have become effective as contemplated by 
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, 
will comply with the prospectus delivery requirements of the Securities Act as 
applicable to it in connection with sales of Registrable Securities pursuant 
to the Registration Statement.

          Each Holder agrees by its acquisition of such Registrable Securities 
that, upon receipt of a notice from the Company of the occurrence of any event 
of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or 
3(c)(vi), such Holder will forthwith discontinue disposition of such 
Registrable Securities under the Registration Statement until such Holder's 
receipt of the copies of the supplemented Prospectus and/or amended 
Registration Statement contemplated by Section 3(j), or until it is advised in 
writing (the "ADVICE") by the Company that the use of the applicable 
Prospectus may be resumed, and, in either case, has received copies of any 
additional or supplemental filings that are incorporated or deemed to be 
incorporated by reference in such Prospectus or Registration Statement.

responsible for, and the Company shall be required to pay the fees or 
disbursements incurred by the Company (including by its legal counsel and 
accountants) in connection with, the preparation and filing of a Registration 
Statement and related Prospectus for such offering, the maintenance of such 
Registration Statement in accordance with the terms hereof, the listing of the 
Registrable Securities in accordance with the requirements hereof, and 
printing expenses incurred to comply with the requirements hereof.

     5.   INDEMNIFICATION

                                     -10-



          (a)  INDEMNIFICATION BY THE COMPANY.  The Company shall, 
notwithstanding any termination of this Agreement, indemnify and hold harmless 
each Holder, the officers, directors, agents (including any underwriters 
retained by such Holder in connection with the offer and sale of Registrable 
Securities), brokers (including brokers who offer and sell Registrable 
Securities as principal as a result of a pledge or any failure to perform 
under a margin call of Common Stock), investment advisors and employees of 
each of them, each Person who controls any such Holder (within the meaning of 
Section 15 of the Securities Act or Section 20 of the Exchange Act) and the 
officers, directors, agents and employees of each such controlling Person, to 
the fullest extent permitted by applicable law, from and against any and all 
losses, claims, damages, liabilities, costs (including, without limitation, 
costs of preparation and attorneys' fees) and expenses (collectively, 
"LOSSES"), as incurred, arising out of or relating to any untrue or alleged 
untrue statement of a material fact contained in the Registration Statement, 
any Prospectus or any form of prospectus or in any amendment or supplement 
thereto or in any preliminary prospectus, or arising out of or relating to any 
omission or alleged omission of a material fact required to be stated therein 
or necessary to make the statements therein (in the case of any Prospectus or 
form of prospectus or supplement thereto, in light of the circumstances under 
which they were made) not misleading, except to the extent, but only to the 
extent, that such untrue statements or omissions are based solely upon 
information regarding such Holder furnished in writing to the Company by such 
Holder expressly for use therein, or to the extent that such information 
relates to such Holder or such Holder's proposed method of distribution of 
Registrable Securities and was reviewed and expressly approved in writing by 
such Holder expressly for use in the Registration Statement, such Prospectus 
or such form of Prospectus or in any amendment or supplement thereto.  The 
Company shall notify the Holders promptly of the institution, threat or 
assertion of any Proceeding of which the Company is aware in connection with 
the transactions contemplated by this Agreement.

          (b)  INDEMNIFICATION BY HOLDERS.  Each Holder shall, severally and 
not jointly, indemnify and hold harmless the Company, its directors, officers, 
agents and employees, each Person who controls the Company (within the meaning 
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and 
the directors, officers, agents or employees of such controlling Persons, to 
the fullest extent permitted by applicable law, from and against all Losses 
(as determined by a court of competent jurisdiction in a final judgment not 
subject to appeal or review) arising solely out of or based solely upon any 
untrue statement of a material fact contained in the Registration Statement, 
any Prospectus, or any form of prospectus, or in any amendment or supplement 
thereto, or arising solely out of or based solely upon any omission of a 
material fact required to be stated therein or necessary to make the 
statements therein not misleading to the extent, but only to the extent, that 
such untrue statement or omission is contained in any information so furnished 
in writing by such Holder to the Company specifically for inclusion in the 
Registration Statement or such Prospectus or to the extent that such 
information relates to such Holder or such Holder's proposed method of 
distribution of Registrable Securities and was reviewed and expressly approved 
in writing by such Holder expressly for use in the Registration Statement, 
such Prospectus or such form of Prospectus, or in any amendment or supplement 
thereto.  In no event shall the liability of any selling Holder hereunder be 
greater in amount than the dollar amount of the net proceeds received by such 
Holder upon the sale of the Registrable Securities giving rise to such 
indemnification obligation.

                                     -11-



          (c)  CONDUCT OF INDEMNIFICATION PROCEEDINGS. If any Proceeding shall 
be brought or asserted against any Person entitled to indemnity hereunder (an 
"INDEMNIFIED PARTY"), such Indemnified Party shall promptly notify the Person 
from whom indemnity is sought (the "INDEMNIFYING PARTY") in writing, and the 
Indemnifying Party shall assume the defense thereof, including the employment 
of counsel reasonably satisfactory to the Indemnified Party and the payment of 
all fees and expenses incurred in connection with defense thereof; provided, 
that the failure of any Indemnified Party to give such notice shall not 
relieve the Indemnifying Party of its obligations or liabilities pursuant to 
this Agreement, except (and only) to the extent that it shall be finally 
determined by a court of competent jurisdiction (which determination is not 
subject to appeal or further review) that such failure shall have proximately 
and materially adversely prejudiced the Indemnifying Party.

          An Indemnified Party shall have the right to employ separate counsel 
in any such Proceeding and to participate in the defense thereof, but the fees 
and expenses of such counsel shall be at the expense of such Indemnified Party 
or Parties unless:  (1) the Indemnifying Party has agreed in writing to pay 
such fees and expenses; or (2) the Indemnifying Party shall have failed 
promptly to assume the defense of such Proceeding and to employ counsel 
reasonably satisfactory to such Indemnified Party in any such Proceeding; or 
(3) the named parties to any such Proceeding (including any impleaded parties) 
include both such Indemnified Party and the Indemnifying Party, and such 
Indemnified Party shall have been advised by counsel that a conflict of 
interest is likely to exist if the same counsel were to represent such 
Indemnified Party and the Indemnifying Party (in which case, if such 
Indemnified Party notifies the Indemnifying Party in writing that it elects to 
employ separate counsel at the expense of the Indemnifying Party, the 
Indemnifying Party shall not have the right to assume the defense thereof and 
such counsel shall be at the expense of the Indemnifying Party).  The 
Indemnifying Party shall not be liable for any settlement of any such 
Proceeding effected without its written consent, which consent shall not be 
unreasonably withheld.  No Indemnifying Party shall, without the prior written 
consent of the Indemnified Party, effect any settlement of any pending 
Proceeding in respect of which any Indemnified Party is a party, unless such 
settlement includes an unconditional release of such Indemnified Party from 
all liability on claims that are the subject matter of such Proceeding.

          All fees and expenses of the Indemnified Party (including reasonable 
fees and expenses to the extent incurred in connection with investigating or 
preparing to defend such Proceeding in a manner not inconsistent with this 
Section) shall be paid to the Indemnified Party, as incurred, within ten (10) 
Business Days of written notice thereof to the Indemnifying Party (regardless 
of whether it is ultimately determined that an Indemnified Party is not 
entitled to indemnification hereunder; 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).

          (d)  CONTRIBUTION.  If a claim for indemnification under Section 
5(a) or 5(b) is unavailable to an Indemnified Party (by reason of public 
policy or otherwise), then each Indemnifying Party, in lieu of indemnifying 
such Indemnified Party, shall contribute to the amount paid or payable by such 
Indemnified Party as a result of such Losses, in such proportion as is 
appropriate to reflect the relative fault of the Indemnifying Party and 
Indemnified Party in 

                                     -12-



connection with the actions, statements or omissions that resulted in such 
Losses as well as any other relevant equitable considerations. The relative 
fault of such Indemnifying Party and Indemnified Party shall be determined by 
reference to, among other things, whether any action in question, including 
any untrue or alleged untrue statement of a material fact or omission or 
alleged omission of a material fact, has been taken or made by, or relates to 
information supplied by, such Indemnifying Party or Indemnified Party, and the 
parties' relative intent, knowledge, access to information and opportunity to 
correct or prevent such action, statement or omission.  The amount paid or 
payable by a party as a result of any Losses shall be deemed to include, 
subject to the limitations set forth in Section 5(c), any reasonable 
attorneys' or other reasonable fees or expenses incurred by such party in 
connection with any Proceeding to the extent such party would have been 
indemnified for such fees or expenses if the indemnification provided for in 
this Section was available to such party in accordance with its terms.

          The parties hereto agree that it would not be just and equitable if 
contribution pursuant to this Section 5(d) were determined by PRO RATA 
allocation or by any other method of allocation that does not take into 
account the equitable considerations referred to in the immediately preceding 
paragraph. Notwithstanding the provisions of this Section 5(d), no Holder 
shall be required to contribute, in the aggregate, any amount in excess of the 
amount by which the proceeds actually received by such Holder from the sale of 
the Registrable Securities subject to the Proceeding exceeds the amount of any 
damages that such Holder has otherwise been required to pay by reason of such 
untrue or alleged untrue statement or omission or alleged omission.  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.

          The indemnity and contribution agreements contained in this Section 
are in addition to any liability that the Indemnifying Parties may have to the 
Indemnified Parties.

     6.   MISCELLANEOUS

          (a)  REMEDIES.  In the event of a breach by the Company or by a 
Holder, of any of their obligations under this Agreement, each Holder or the 
Company, as the case may be, in addition to being entitled to exercise all 
rights granted by law and under this Agreement, including recovery of damages, 
will be entitled to specific performance of its rights under this Agreement. 
The Company and each Holder agree that monetary damages would not provide 
adequate compensation for any losses incurred by reason of a breach by it of 
any of the provisions of this Agreement and hereby further agrees that, in the 
event of any action for specific performance in respect of such breach, it 
shall waive the defense that a remedy at law would be adequate.

          (b)  NO INCONSISTENT AGREEMENTS.  Except as and to the extent 
specified in SCHEDULE 6(b) hereto, neither the Company nor any of its 
subsidiaries has, as of the date hereof, nor shall the Company or any of its 
subsidiaries, on or after the date of this Agreement, enter into any agreement 
with respect to its securities that is inconsistent with the rights granted to 
the Holders in this Agreement or otherwise conflicts with the provisions 
hereof. Except as and to the extent specified in SCHEDULE 6(b) hereto, neither 
the Company nor any of its subsidiaries has previously 

                                     -13-



entered into any agreement granting any registration rights with respect to 
any of its securities to any Person.  Without limiting the generality of the 
foregoing, without the written consent of the Holders of a majority of the 
then outstanding Registrable Securities, the Company shall not grant to any 
Person the right to request the Company to register any securities of the 
Company under the Securities Act unless the rights so granted are subject in 
all respects to the prior rights in full of the Holders set forth herein, and 
are not otherwise in conflict or inconsistent with the provisions of this 
Agreement.

          (c)  NO PIGGYBACK ON REGISTRATIONS.  Except as and to the extent 
specified in SCHEDULE 6(b) hereto, neither the Company nor any of its security 
holders (other than the Holders in such capacity pursuant hereto) may include 
securities of the Company in the Registration Statement other than the 
Registrable Securities, and the Company shall not after the date hereof enter 
into any agreement providing any such right to any of its security holders.

          (d)  PIGGY-BACK REGISTRATIONS.  If at any time when there is not an 
effective Registration Statement covering all of the Registrable Securities 
and the Underlying Shares, the Company shall determine to prepare and file 
with the Commission a registration statement relating to an offering for its 
own account or the account of others (other than pursuant to the registration 
rights granted to the holders of the 1997 Subordinated Convertible Notes and 
the warrants issued in connection therewith) under the Securities Act of any 
of its equity securities, other than on Form S-4 or Form S-8 (each as 
promulgated under the Securities Act) or their then equivalents relating to 
equity securities to be issued solely in connection with any acquisition of 
any entity or business or equity securities issuable in connection with stock 
option or other employee benefit plans, then the Company shall send to each 
holder of Registrable Securities written notice of such determination and, if 
within twenty (20) days after receipt of such notice, any such holder shall so 
request in writing, the Company shall include in such registration statement 
all or any part of such Registrable Securities such holder requests to be 
registered; PROVIDED, HOWEVER, that the Company shall not be required to 
register any Registrable Securities pursuant to this Section 7(d) that are 
eligible for sale pursuant to Rule 144(k) of the Commission.

          (e)  AMENDMENTS AND WAIVERS.  The provisions of this Agreement, 
including the provisions of this sentence, may not be amended, modified or 
supplemented, and waivers or consents to departures from the provisions hereof 
may not be given, unless the same shall be in writing and signed by the 
Company and the Holders of at least two-thirds of the then outstanding 
Registrable Securities; PROVIDED, HOWEVER, that, for the purposes of this 
sentence, Registrable Securities that are owned, directly or indirectly, by 
the Company, or an Affiliate of the Company are not deemed outstanding.  
Notwithstanding the foregoing, a waiver or consent to depart from the 
provisions hereof with respect to a matter that relates exclusively to the 
rights of Holders and that does not directly or indirectly affect the rights 
of other Holders may be given by Holders of at least a majority of the 
Registrable Securities to which such waiver or consent relates; PROVIDED, 
HOWEVER, that the provisions of this sentence may not be amended, modified, or 
supplemented except in accordance with the provisions of the immediately 
preceding sentence.

                                     -14-

Transaction Documents), and hereby irrevocably waives, and agrees not to 
assert in any suit, action or proceeding, any claim that it is not personally 
subject to the jurisdiction of any such court, that such suit, action or 
proceeding is improper.  Each party hereby irrevocably waives personal service

proceeding by mailing a copy thereof to such party at the address in effect

          (j)  CUMULATIVE REMEDIES.  The remedies provided herein are 
cumulative and not exclusive of any remedies provided by law.

          (k)  SEVERABILITY. If any term, provision, covenant or restriction

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 reasonable 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 such that may be hereafter declared invalid, illegal, 
void or unenforceable.

          (l)  HEADINGS.  The headings in this Agreement are for convenience 
of reference only and shall not limit or otherwise affect the meaning hereof.

          (m)  SHARES HELD BY THE COMPANY AND ITS AFFILIATES.  Whenever the 
consent or approval of Holders of a specified percentage of Registrable 
Securities is required hereunder, Registrable Securities held by the Company 
or its Affiliates (other than any Holder or transferees or successors or 
assigns thereof if such Holder is deemed to be an Affiliate solely by reason 
of its holdings of such Registrable Securities) shall not be counted in 
determining whether such consent or approval was given by the Holders of such 
required percentage.

     The Selling Stockholders and any of their pledgees, assignees and 
successors-in-interest may, from time to time, sell any or all of their shares 
of Common Stock on any stock exchange, market or trading facility on which the 
shares are traded or in private transactions.  These sales may be at fixed or 
negotiated prices.  The Selling Stockholders may use any one or more of the 
following methods when selling shares:

     -    ordinary brokerage transactions and transactions in which the 
          broker-dealer solicits purchasers;

     -    block trades in which the broker-dealer will attempt to sell the 
          shares as agent but may position and resell a portion of the block
          as principal to facilitate the transaction;
     
     -    purchases by a broker-dealer as principal and resale by the 
          broker-dealer for its account;
     
     -    an exchange distribution in accordance with the rules of the 
          applicable exchange;
     
     -    privately negotiated transactions;
     
     -    short sales;
     
     -    broker-dealers may agree with the Selling Stockholders to sell a 
          specified number of such shares at a stipulated price per share;
     
     -    a combination of any such methods of sale; and
     
     -    any other method permitted pursuant to applicable law.

     The Selling Stockholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

     The Selling Stockholders may also engage in short sales against the box,
puts and calls and other transactions in securities of the Company or
derivatives of Company securities and may sell or deliver shares in connection
with these trades.  The Selling Stockholders may pledge their shares to their
brokers under the margin provisions of customer agreements.  If a Selling
Stockholder defaults on a margin loan, the broker may, from time to time, offer
and sell the pledged shares.

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



     The Selling Stockholders and any broker-dealers or agents that are involved
in selling the shares may be deemed to be "underwriters" within the meaning of
the Securities Act in connection with such sales.  In such event, any
commissions received by such broker-dealers or agents and any profit on the
resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act.

     The Company is required to pay all fees and expenses incident to the
registration of the shares, including fees and disbursements of counsel to the
Selling Stockholders.  The Company has agreed to indemnify the Selling
Stockholders against certain losses, claims, damages and liabilities, including
liabilities under the Securities Act.



                                                                    EXHIBIT  E

                            TRANSFER AGENT INSTRUCTIONS

Ladies and Gentlemen:

     Reference is made to that certain Convertible Preferred Stock Purchase
Agreement (the "PURCHASE AGREEMENT") between TRO Learning, Inc., a Delaware
corporation (the "COMPANY"), and the buyers named therein (the "HOLDERS")
pursuant to which the Company is issuing to the Holders its shares of Series C
Convertible Preferred Stock, par value $.01 per share (the "PREFERRED SHARES"),
and a Common Stock purchase warrant (the "WARRANT") which shall be convertible
and exercisable, respectively, into shares of the Company's common stock, $.01
par value per share (the "COMMON STOCK"). The shares of Common Stock issuable
upon conversion of the Preferred Shares and upon exercise of the Warrants are
collectively referred to herein as "UNDERLYING SHARES."

     This letter shall serve as our irrevocable authorization and direction to
you (provided that you are the transfer agent for the Company with respect to
its Common Stock at such time) to issue Underlying Shares from time to time upon
notice from the Company to issue such Underlying Shares.

     So long as you have previously received (x) a direction letter from the
Company substantially in the form of EXHIBIT I attached hereto stating that a
registration statement covering resales of Underlying Shares has been declared
effective by the Securities and Exchange Commission under the Securities Act of
1933, as amended, and that Underlying Shares may be issued (or reissued if they
have been issued at a time when there was not such an effective registration
statement) or resold without any restrictive legend (the "DIRECTION LETTER") and
(y) a copy of such registration statement, certificates representing Underlying
Shares shall not bear any legend restricting transfer of Underlying Shares
thereby and should not be subject to any stop-transfer restriction. Provided, 
however, that if you have not previously received (x) a copy of the Direction 
Letter and (y) a copy of such registration statement, then the certificates 
representing Underlying Shares shall bear the following legend:

          THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND 
     EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE 
     UPON AN EXEMPTION FROM REGISTRATION



     UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
     AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
     EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN
     AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
     REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH
     APPLICABLE STATE SECURITIES LAWS.

and, provided, further, that the Company may, from time to time, notify you to
place stop-transfer restrictions on the certificates for Underlying Shares in
the event, but only in the event, a registration statement covering Underlying
Shares is subject to amendment for events then current.

     Please be advised that the Holders have relied upon this instruction letter
as an inducement to enter into the Purchase Agreement and, accordingly, the
Holders are a third party beneficiary to these instructions.

     Please execute this letter in the SPACE indicated to acknowledge your
agreement to act in accordance with these instructions. Should you have any
questions concerning this matter, please contact me at (612) 832-1413.

                                        Very truly yours,
