on the financial condition of enherent and its subsidiaries taken as a whole or the ability of the Parties to consummate the transactions contemplated by this Agreement.



4. REPRESENTATIONS AND WARRANTIES OF PREFERRED STOCKHOLDERS.Each of the Preferred Stockholders represents and
warrants to enherent that the statements contained in this §4 are correct and complete as applied to it as of the date of this Agreement.

formation.



(b) Authority; Enforceability. The Preferred
Stockholder has full power and authority (including full corporate power and authority) to execute and deliver this Agreement and to perform its obligations under this Agreement. The execution, delivery and performance by the Preferred Stockholder
of this Agreement has been duly authorized by the Preferred Stockholder. This Agreement is a valid and binding agreement of the Preferred Stockholder enforceable against it in accordance with its terms, except as the same may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting generally the enforcement of creditors rights, remedies and general principals of equity, including any limitations of the availability of the remedy of
specific performance or injunctive relief regardless of whether specific performance or injunctive relief is sought in a proceeding at law or in equity.



(c) Noncontravention. To the knowledge of each Preferred Stockholder, neither the execution and the delivery of this Agreement, nor the
consummation of the contemplated transactions, will (i) violate any constitution, statute, regulation, rule, injunction, judgment, order, decree, ruling, charge, or other restriction of any government, governmental agency, or court to which the
Preferred Stockholder is subject or any provision of the organizational documents of the Preferred Stockholder or (ii) conflict with, result in a breach of, constitute a default under, result in the acceleration of, create in any party the right to

subject, except where the violation, conflict, breach, default, acceleration, termination, modification, cancellation, or failure to give notice would not have a material adverse effect on the financial condition of the Preferred Stockholder taken
as a whole or the ability of the Parties to consummate the transactions contemplated by this Agreement.



(d) Investment Intent. The Preferred Stockholder is acquiring the enherent Shares issued pursuant to the Disposition for investment and not with a
view to, or for resale in connection with, any distribution thereof for purposes of the Securities Act. The Preferred Stockholder is an accredited investor as such term is defined in regulation D under the Securities Act. The
Preferred Stockholder acknowledges that half of the enherent Shares issued to the Preferred Stockholder pursuant to the Disposition shall be restricted securities within the meaning of Rule 144 under the Securities Act (Rule
144), will contain a transfer restriction legend and may only be resold pursuant to an effective registration statement filed with the SEC under the Securities Act, or pursuant to Rule 144 or another valid exemption from the registration
requirements of the Securities Act as established by an opinion of counsel reasonably acceptable to enherent.



5. REGISTRATION.



(a) Definitions. For purposes of this §5:



(i) The terms register, registered, and registration refer to a registration
effected by preparing and filing a registration statement or similar document in compliance with the Securities Act, and the declaration or ordering of effectiveness of such registration statement or document;



- 4 -



---

(ii) The term Registrable Securities means the Restricted Shares;
provided, however, that as to any particular security or securities that are contained in the Registrable Securities, such securities shall cease to be Registrable Securities when (1) a registration statement with respect to the sale of such
securities shall have become effective under the Securities Act and such securities shall have been disposed of in accordance with such registration statement or (2) such securities shall have been sold to the public pursuant to Rule 144;



(iii) The term Holder
means any Person owning or having the right to acquire Registrable Securities or any assignee thereof in accordance with the provisions of §5(f) hereof; and



(iv) The term Form S-3 means such form under the Securities Act as in effect on the date
hereof or any registration form under the Securities Act subsequently adopted by the SEC which permits inclusion or incorporation of substantial information by reference to other documents filed by enherent with the SEC.



(b) Shelf Registration.



(i) In no event later than October 10, 2005, enherent shall
file with the SEC a shelf registration statement on Form S-3 (or if Form S-3 is not available, then such other form on which the Registrable Securities may be registered for resale) under the Securities Act with respect to the registration of the
Restricted Shares, provided that enherent may, with the prior written approval of the Holders, delay such filing (but not beyond 90 days after October 10, 2005) if such filing would require enherent to disclose material non-public information, the
disclosure of which would be detrimental to enherent. enherent may include in such registration statement up to 700,000 enherent Shares owned by Douglas Catalano, 4,526,512 enherent Shares owned by Pamela Fredette and 500,000 enherent shares
underlying options issued to Douglas Mellinger, and may, with the approval of the Holders, include in such registration statement securities of enherent to be offered and sold by enherent. enherent shall use its best efforts to cause such
registration statement to be declared effective within 90 days after it is filed.



(ii) The Holders shall promptly notify enherent of the jurisdictions in which such offering will be made and, if and as required and
subject to the provisions of clause (iv)(D), below, enherent shall effect the registration and/or qualification of the Restricted Shares under applicable state securities laws (the State Laws).



(iii) Except as otherwise prohibited by applicable law,
enherent will pay all fees and expenses, including, without limitation, printing and reproduction costs and fees and expenses of counsel for Holders, incurred in connection with the registration of the Restricted Shares pursuant to this §5;
provided, that transfer taxes, if any, solely attributable to the sale of the Restricted Shares, shall be borne by the Holders.



(iv) enherent shall further:



(1) prepare and file as soon as reasonably practicable with the SEC such amendments and supplements to such shelf registration statement
and the prospectus used in connection therewith as may be necessary to keep such registration statement effective and such prospectus current and to comply with the provisions of the Securities Act with respect to the disposition of the Restricted
Shares until the earlier of (A) such time as all of the Restricted Shares have been disposed of; or (B) such time as the Restricted Shares are otherwise freely tradeable;



(2) furnish to Holders copies of the preliminary prospectus and prospectus included in such registration
statement and each amendment and supplement thereto;



(3) use its best efforts to register or qualify the Restricted Shares under the State Laws after the filing of the Form S-3 registration statement (or any other registration form for which enherent then qualifies) with the SEC and to keep
such registration or qualification in effect for so long as the Form S-3 registration statement (or any other registration form for which enherent then qualifies) filed with the SEC remains in effect as provided in clause (2), above, provided that
enherent shall not for any such purpose be required to qualify generally to do business as a foreign corporation



- 5 -



---

in any jurisdiction in which it would not otherwise be obligated to be so qualified, or to subject itself
to taxation in any such jurisdiction, or to consent to general service of process in any such jurisdiction, or to qualify as a dealer in securities; and



(4) notify Holders, at any time when a prospectus is required to be delivered by Holders under the Securities Act, upon discovery by
enherent that the prospectus included in such registration statement, 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 light of the circumstances then existing, whereupon Holders shall suspend any offers or sales of the Restricted Shares until such time as such prospectus, as amended or supplemented from time to time, shall not 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 not misleading in light of the circumstances then existing. Except as otherwise approved by the Holders, the
period of time in which offers or sales of the Restricted Securities are suspended shall not exceed thirty (30) days in any twelve month period.



(v) The Holders agree to cooperate fully with enherent in connection with effecting the registration pursuant to this §5, including,
but not limited to, furnishing such information as enherent may from time to time reasonably request and as shall be required by law or by the SEC in connection with such registration and cooperating with the preparation and filing of any amendments
to the shelf registration statement or prospectus.



(c)
Obligations of enherent. Whenever required under this Agreement to maintain a registration statement for the sale of any Registrable Securities, enherent shall use its best efforts to list the Registrable Securities covered by such
registration statement with any securities exchange on which the enherent Shares are then listed and provide a transfer agent and registrar for all Registrable Securities registered hereunder and a CUSIP number for all such Registrable Securities
within the time frames set forth in §5(b) hereof.



(d)
Indemnification.



(i) To the extent
permitted by law, enherent will indemnify and hold harmless each Holder of Registrable Securities and such Holders officers and directors, and each Person, if any, who controls such Holder within the meaning of the Securities Act or the
Exchange Act (each, an Indemnitee), against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, or the Exchange Act or other federal or state law, insofar as
such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a Violation): (1) any untrue statement or alleged
untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (2) 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, or (3) any violation or alleged violation by enherent of the Securities Act, the Exchange Act, any state securities law or any rule or
regulation promulgated under the Securities Act, or the Exchange Act or any state securities law; and enherent will pay to each such Indemnitee any legal or other expenses reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this §5(d)(i) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is
effected without the consent of enherent (which consent shall not be unreasonably withheld), nor shall enherent be liable in any such case for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a
Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Indemnitee. Notwithstanding the above, the foregoing indemnity agreement is subject to
the condition that, insofar as it relates to any such untrue statement, alleged untrue statement, omission or alleged omission made in a preliminary prospectus, such indemnity agreement shall not inure to the benefit of any Holder if a copy of the
final prospectus was not furnished to the Person asserting the loss, liability, claim or damage at or prior to the time such action is required by the Securities Act if the final prospectus corrected the untrue statement or omission or alleged
untrue statement or omission and was (A) provided to the Holder, and (B) such Holder was required by applicable law to deliver such prospectus.



- 6 -



---

(ii) To the extent permitted by law, each Holder will indemnify and hold harmless
enherent, each of its directors, each of its officers who has signed the registration statement, each Person, if any, who controls enherent within the meaning of the Securities Act, any underwriter, any other Holder selling securities in such
registration statement and any controlling Person of any such underwriter or other Holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing Persons may become subject, under the Securities Act, or
the Exchange Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will pay any legal or other expenses reasonably incurred by any Person
intended to be indemnified pursuant to this §5(d)(ii), in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this §5(d)(ii) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; further provided, that in no event shall any
indemnity under this §5(d)(ii) exceed the net proceeds (excluding underwriting discounts and commissions) from the offering received by such Holder.



(iii) Promptly after receipt by an indemnified party under this §5(d) of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this §5(d), deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying
party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties;
provided, however, that an indemnified party (together with all other indemnified parties which may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the
indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate, in the reasonable judgment of the indemnified party, due to actual or potential differing interests between
such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability
to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this §5(d) to the extent of such prejudice, but the omission so to deliver written notice to the indemnifying party will not relieve it
of any liability that it may have to any indemnified party otherwise than under this §5(d).



(iv) To provide for just and equitable contribution, if (1) an indemnified party makes a claim for indemnification pursuant to
§5(d)(i) or §5(d)(ii) but it is found in a final judicial determination, not subject to further appeal, that such indemnification may not be enforced in such case, even though this Agreement expressly provides for indemnification in such
case, or (2) any indemnified or indemnifying party seeks contribution under the Securities Act, the Exchange Act, or otherwise, then enherent (including for this purpose any contribution made by or on behalf of any officer, director, employee, agent
or counsel of enherent, or any controlling Person of enherent), on the one hand, and the Holders (including for this purpose any contribution by or on behalf of a Holder), on the other hand, shall contribute to the losses, liabilities, claims,
damages, and expenses to which any of them may be subject, in such proportions as are appropriate to reflect the relative fault of enherent and the Holders in connection with the facts which resulted in such losses, liabilities, claims, damages, and
expenses shall also be considered.



The
relative fault, in the case of an untrue statement, alleged untrue statement, omission, or alleged omission, shall be determined by, among other things, whether such statement, alleged statement, omission, or alleged omission relates to information
supplied by enherent or by the Holders, and the parties relative intent, knowledge, access to information, and opportunity to correct or prevent such statement, alleged statement, omission, or alleged omission. enherent and Holders agree that
it would be unjust and inequitable if the respective obligations of enherent and the Holders for contribution were determined by pro rata or per capita allocation of the aggregate losses, liabilities, claims, damages, and expenses or by any other
method of allocation that does not reflect the equitable considerations referred to in this §5(d)(iv). No Person guilty of a fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who is not guilty of such fraudulent misrepresentation. For purposes of this



- 7 -



---

§5(d)(iv), each Person, if any, who controls a Holder within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act and each officer, director, stockholder, employee, agent, and counsel of the Holders, shall have the same rights of contribution as the Holder, and each Person, if any, who controls enherent within
the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act and each officer, director, employee, agent, and counsel of enherent, shall have the same rights to contribution as enherent, subject in each case to the provisions
of this §5(d)(iv). Anything in this §5(d)(iv) to the contrary notwithstanding, no party shall be liable for contribution with respect to the settlement of any claim or action effected without its written consent. This §5(d)(iv) is
intended to supersede any right to contribution under the Securities Act, the Exchange Act, or otherwise.



(v) Notwithstanding the foregoing §5(d)(iv), if the indemnification provided for in the preceding provisions of this §5(d) is
unavailable to an indemnified party in respect of any expense, loss, claim, damage or liability referred to therein, 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 expense, loss, claim, damage or liability (1) in such proportion as is appropriate to reflect the relative benefits received by enherent on the one hand and the Holder or underwriter, as the case may be, on the
other from the distribution of the Registrable Securities or (2) if the allocation provided by clause (1) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause
(1) above but also the relative fault of enherent on the one hand and of the Holder or underwriter, as the case may be, on the other in connection with the statements or omissions which resulted in such expense, loss, damage or liability, as well as
any other relevant equitable considerations.



Notwithstanding the provisions of subdivision (iv) or this subdivision (v), no Holder of Registrable Securities or underwriter shall be required to contribute any amount in excess of the amount by which (A) in the case of any such Holder,
the net proceeds received by such Holder from the sale of Registrable Securities or (B) in the case of an underwriter, the total price at which the Registrable Securities purchased by it and distributed to the public were offered to the public
exceeds, in any such case, the amount of any damages that such holder or underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission.



(vi) The obligations of enherent and Holders under this §5(d) shall survive the completion of any
offering of Registrable Securities under this Agreement, and otherwise.



(e) Reports Under Exchange Act. With a view to making available to the Holders of Registrable Securities the benefits of a registration on Form S-3, enherent agrees to:



(i) make and keep public information available, as those terms are understood and defined in Rule 144, at
all times;



(ii) take such action as is
necessary to enable the Holders to utilize Form S-3 (or any other registration form for which enherent then qualifies) for the sale of their Registrable Securities;



(iii) file with the SEC in a timely manner all reports and other documents required of enherent under the
Securities Act and the Exchange Act; and



(iv)
furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (1) a written statement by enherent that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, and
that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after it so qualifies), (2) a copy of the most recent annual or quarterly report of enherent and such other reports and documents so filed by
enherent, and (3) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form.



(f) Assignment of Registration Rights. The rights to require enherent
to register Registrable Securities pursuant to this Agreement may be assigned (but only with all related obligations) by a Holder to a transferee or assignee



- 8 -



---

of such Registrable Securities, provided: (i) enherent is furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such registration rights are being assigned; (ii) immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the
Securities Act; (iii) such transferee or assignee delivers to enherent a written instrument by which such transferee agrees to be bound by the obligations imposed upon Holders of Registrable Securities pursuant to this Agreement; (iv) any such
transferee or assignee may not again transfer such rights to any other Person or entity, other than as provided in this §5(f); and (v) such transfer is in compliance with applicable federal and state securities laws and, at enherents
option, enherent has received an opinion of counsel to such effect, the cost and expenses of such opinion of counsel to be borne by the transferring Holder.



(g) Limitations on Subsequent Registration Rights. From and after the date of this Agreement, enherent shall not, without the prior written consent
of the Holders of 70% of the Registrable Securities, enter into any agreement with any holder or prospective holder of any securities of enherent which would allow such holder or prospective holder to include such securities in any registration
statement filed under this Agreement, unless under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of his securities will not reduce the amount
of the Registrable Securities of the Holders which is included.



(h) Amendment of Registration Rights. Any provision of this §5 may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively) only with the
written consent of enherent and the Holders of 70% of the Registrable Securities. Any amendment or waiver effected in accordance with this paragraph shall be binding upon each Holder of any Registrable Securities then outstanding, each future Holder
of all such Registrable Securities and enherent.



6.
