PART I.  INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS

     Item 1.  Plan Information.
              ---------------- 
     The information required by Part I is included in documents sent or
given to participants in the 1997 Employee Stock Incentive Plan of Shiva
Corporation, a Massachusetts corporation (the "Registrant"), pursuant to
Rule 428(b)(1) of the Securities Act of 1933, as amended (the "Securities
Act").

PART II.  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

     Item 3.  Incorporation of Certain Documents by Reference.
              -----------------------------------------------
     The Registrant is subject to the informational and reporting require-
ments of Sections 13(a), 14, and 15(d) of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and in accordance therewith files
reports, proxy statements and other information with the Securities and
Exchange Commission (the "Commission").  The following documents, which
are filed with the Commission, are incorporated in this Registration
Statement by reference:

     (a)  The Registrant's latest annual report filed pursuant to Section
13(a) or 15(d) of the Exchange Act or either (1) the latest prospectus
filed pursuant to Rule 424(b) under the Securities Act that contains audited
financial statements for the Registrant's latest fiscal year for which such
financial statements have been filed or (2) the Registrant's effective
registration statement on Form 10 or 20-F filed under the Exchange Act
containing audited financial statements for the Registrant's latest fiscal
year.

     (b)  All other reports filed pursuant to Section 13(a) or 15(d) of the
Exchange Act since the end of the fiscal year covered by the Registrant
document referred to in (a) above.

     (c)  The description of the Common Stock which is contained in a
registration statement filed under the Exchange Act, including any amendment
or report filed for the purpose of updating such description.

All documents subsequently filed by the Registrant pursuant to Sections
13(a), 13(c), 14, and 15(d) of the Exchange Act prior to the filing of a
post-effective amendment which indicates that all shares of Common Stock
offered hereby have been sold or which deregisters all shares of Common
Stock then remaining unsold, shall be deemed to be incorporated by reference
herein and to be part hereof from the date of the filing of such documents.
Any statement contained in a document incorporated or deemed to be incor-
porated by reference herein shall be deemed to be modified or superseded
for the purposes of this Registration Statement to the extent a statement
contained herein or in any other subsequently filed document which also 
is or is deemed to be incorporated by reference herein modifies or super-
sedes such statement.  Any statement so modified or superseded shall not
be deemed, except as so modified or superseded, to constitute a part of
this Registration Statement.

     Item 4.  Description of Securities.

<PAGE>

     Item 6.  Indemnification.
              ---------------
     Article 6 of the Registrant's Restated Articles of Organization, as
amended, provides that no director of the Registrant shall be liable for
any breach of fiduciary duty except to the extent that (1) the Massachusetts
Corporation Law prohibits the elimination or limitation of liability of
directors for breach of fiduciary duty or (2) the act or omission occurred
prior to the effective date of the provision.

     Section 2 of Article V of the Registrant's Restated By-Laws, as amended
(the "By-Laws"), provides that directors, officers, employees and other
agents of the Registrant and any person who, at the request of the corpora-
tion, serves as a director, officer, employee or other agent of another
organization in which the Registrant directly or indirectly owns shares or
of which it is a creditor shall be indemnified by the Registrant against
all cost, expense (including attorneys' fees), judgment, liability and/or
amount paid in settlement reasonably incurred by or imposed upon him in
connection with any action, suit or proceeding (including any proceeding
before any administrative or legislative body or agency) to which he may
be made a party or otherwise involved or with which he shall be threatened,
by reason of his being, or related to his status as a director, officer,
employee or other agent of the Registrant or of any other organization in
which the Registrant directly or indirectly owns shares or of which the
Registrant is a creditor, which other organization he serves or has served
as director, officer, employee or other agent at the request of the
Registrant (whether or not he continues to be an officer, director,
employee or other agent of the corporation or such other organization at
the time such action, suit or proceeding is brought or threatened), unless
such indemnification is prohibited by the Business Corporation Law of the
Commonwealth of Massachusetts.

     Chapter 156B of the General Laws of Massachusetts (the "Massachusetts
Business Corporation Law") prohibits the elimination or limitation of
directors' liability for any of the following:

     (a)  Breaches of the director's duty of loyalty to the Registrant
          or its stockholders;

     (b)  Acts or omissions not in good faith or which involve intentional
          misconduct or a knowing violation of law;

     (c)  Acts covered by Sections 61 or 62 of the Massachusetts Business
          Corporation Law (which relate generally to the liability of
          directors for authorizing distributions to stockholders at a
          time when the Registrant is insolvent or bankrupt and the
          liability of directors for approving loans to officers or
          directors of the Registrant which are not repaid and which were
          not approved or ratified by a majority of disinterested directors
          or stockholders); and

     (d)  Transactions from which the director derived an improper personal
          benefit.

     The Massachusetts Business Corporation Law authorizes Massachusetts
corporations to indemnify directors and officers for actions taken in good
faith and in a manner such person reasonably believed to be in the best
interests of the corporation.

     The right of indemnification is in addition to any rights to which any
such person may otherwise be entitled and inures to the benefit of the
executors or administrators of each such person.  The Registrant may pay
the expenses incurred by any such person in defending a civil or criminal
action, suit or proceeding in advance of the final disposition of such
action, suit or proceeding, upon receipt of an undertaking by such person
to repay such payment if it is determined that such person is not entitled
to indemnification hereunder.  This section is subject to amendment or
repeal only by action of the stockholders.

                                   3
<PAGE>

     The Registrant maintains on behalf of its directors and officers
insurance protection against certain liabilities arising out of the dis-
charge of their duties.  The Registrant also maintains insurance covering
the Registrant against indemnification payments to its directors and
officers for certain liabilities.  However, to the extent such coverage is
inadequate to cover claims against directors or officers, the Registrant
may be required pursuant to the By-Laws to reimburse the directors or
officers for the uninsured portion of such claims.  In such an event, the
Registrant's indemnification obligations to its directors and officers 
could have a material negative impact on the Registrant's financial condition
and on stockholder equity.

     Item 7.  Exemption from Registration Claimed.
              -----------------------------------
          Not applicable.

     Item 8.  Exhibits.
              --------
          The Exhibit Index immediately preceding the exhibits is
          incorporated herein by reference.

     Item 9.  Undertakings.
              ------------
          1.  The Registrant hereby undertakes:

          (a)   To file, during any period in which offers or sales are
     being made, a post-effective amendment to this registration statement:

          (i)   To include any prospectus required by Section 10(a)(3) of
     the Securities Act;

          (ii)  To reflect in the prospectus any facts or events arising
     after the effective date of the registration statement (or the most
     recent post-effective amendment thereof) which, individually or in
     the aggregate, represent a fundamental change in the information set
     forth in the registration statement.  Notwithstanding the foregoing,
     any increase or decrease in volume of securities offered (if the
     total dollar value of securities offered would not exceed that which
     was registered) and any deviation from the low or high end of the
     estimated maximum offering range may be reflected in the form of
     prospectus filed with the Commission pursuant to Rule 424(b) if, in
     the aggregate, the changes in volume and price represent no more than
     a 20% change in the maximum aggregate offering price set forth in the
     "Calculation of Registration Fee" table in the effective registration
     statement; and
     
          (iii) To include any material information with respect to the
     plan of distribution not previously disclosed in the registration
     statement or any material change to such information in the
     registration statement;

     provided, however that paragraphs (i) and (ii) do not apply if the
     registration statement is on Form S-3 or Form S-8, and the informa-
     tion required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed by the Registrant
     pursuant to Section 13 or Section 15(d) of the Exchange Act that are
     incorporated by reference in the registration statement.

          (b)   That, for the purpose of determining any liability under 
     the Securities Act, each such post-effective amendment shall be
     deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time
     shall be deemed to be the initial bona fide offering thereof.

                                   4
<PAGE>

          (c)   To remove from registration by means of a post-effective
     amendment any of the securities being registered which remain unsold
     at the termination of the offering.

     2.   The Registrant hereby undertakes that, for purposes of determining
any liability under the Securities Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act
(and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated
by reference in the registration statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be in the
initial bona fide offering thereof.

     3.   Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or other-
wise, the Registrant has been advised that in the opinion of the Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question
whether such indemnification by it is against public policy as expressed in
the Securities Act and will be governed by the final adjudication  of such
issue.

                               SIGNATURES

     Pursuant to the requirements of the Securities Act, the Registrant
certifies that it has reasonable grounds to believe that it meets all of
the requirements for filing on Form S-8 and has duly caused this Registra-
ion Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the Town of Bedford, Commonwealth of Massachusetts on the 29th

Rule 428(b)(1) of the Securities Act of 1933, as amended (the "Securities
Act").

PART II.  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

     Item 3.  Incorporation of Certain Documents by Reference.
              -----------------------------------------------
     The Registrant is subject to the informational and reporting require-
ments of Sections 13(a), 14, and 15(d) of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and in accordance therewith files
reports, proxy statements and other information with the Securities and
Exchange Commission (the "Commission").  The following documents, which
are filed with the Commission, are incorporated in this Registration
Statement by reference:

     (a)  The Registrant's latest annual report filed pursuant to Section
13(a) or 15(d) of the Exchange Act or either (1) the latest prospectus
filed pursuant to Rule 424(b) under the Securities Act that contains audited
financial statements for the Registrant's latest fiscal year for which such
financial statements have been filed or (2) the Registrant's effective
registration statement on Form 10 or 20-F filed under the Exchange Act
containing audited financial statements for the Registrant's latest fiscal
year.

     (b)  All other reports filed pursuant to Section 13(a) or 15(d) of the
Exchange Act since the end of the fiscal year covered by the Registrant
document referred to in (a) above.

     (c)  The description of the Common Stock which is contained in a
registration statement filed under the Exchange Act, including any amendment
or report filed for the purpose of updating such description.

All documents subsequently filed by the Registrant pursuant to Sections
13(a), 13(c), 14, and 15(d) of the Exchange Act prior to the filing of a
post-effective amendment which indicates that all shares of Common Stock
offered hereby have been sold or which deregisters all shares of Common
Stock then remaining unsold, shall be deemed to be incorporated by reference
herein and to be part hereof from the date of the filing of such documents.
Any statement contained in a document incorporated or deemed to be incor-
porated by reference herein shall be deemed to be modified or superseded
for the purposes of this Registration Statement to the extent a statement
contained herein or in any other subsequently filed document which also 
is or is deemed to be incorporated by reference herein modifies or super-
sedes such statement.  Any statement so modified or superseded shall not
be deemed, except as so modified or superseded, to constitute a part of
this Registration Statement.

     Item 4.  Description of Securities.
              -------------------------
          Not applicable.

     Item 5.  Interests of Named Experts and Counsel.
              --------------------------------------
          Not applicable.
                                   2
Item 6.  Indemnification.
              ---------------
     Article 6 of the Registrant's Restated Articles of Organization, as
amended, provides that no director of the Registrant shall be liable for
any breach of fiduciary duty except to the extent that (1) the Massachusetts
Corporation Law prohibits the elimination or limitation of liability of
directors for breach of fiduciary duty or (2) the act or omission occurred
prior to the effective date of the provision.

     Section 2 of Article V of the Registrant's Restated By-Laws, as amended
(the "By-Laws"), provides that directors, officers, employees and other
agents of the Registrant and any person who, at the request of the corpora-
tion, serves as a director, officer, employee or other agent of another
organization in which the Registrant directly or indirectly owns shares or
of which it is a creditor shall be indemnified by the Registrant against
all cost, expense (including attorneys' fees), judgment, liability and/or
amount paid in settlement reasonably incurred by or imposed upon him in
connection with any action, suit or proceeding (including any proceeding
before any administrative or legislative body or agency) to which he may
be made a party or otherwise involved or with which he shall be threatened,
by reason of his being, or related to his status as a director, officer,
employee or other agent of the Registrant or of any other organization in
which the Registrant directly or indirectly owns shares or of which the
Registrant is a creditor, which other organization he serves or has served
as director, officer, employee or other agent at the request of the
Registrant (whether or not he continues to be an officer, director,
employee or other agent of the corporation or such other organization at
the time such action, suit or proceeding is brought or threatened), unless
such indemnification is prohibited by the Business Corporation Law of the
Commonwealth of Massachusetts.

     Chapter 156B of the General Laws of Massachusetts (the "Massachusetts
Business Corporation Law") prohibits the elimination or limitation of
directors' liability for any of the following:

     (a)  Breaches of the director's duty of loyalty to the Registrant
          or its stockholders;

     (b)  Acts or omissions not in good faith or which involve intentional
          misconduct or a knowing violation of law;

     (c)  Acts covered by Sections 61 or 62 of the Massachusetts Business
          Corporation Law (which relate generally to the liability of
          directors for authorizing distributions to stockholders at a
          time when the Registrant is insolvent or bankrupt and the
          liability of directors for approving loans to officers or
          directors of the Registrant which are not repaid and which were
          not approved or ratified by a majority of disinterested directors
          or stockholders); and

     (d)  Transactions from which the director derived an improper personal
          benefit.

     The Massachusetts Business Corporation Law authorizes Massachusetts
corporations to indemnify directors and officers for actions taken in good
faith and in a manner such person reasonably believed to be in the best
interests of the corporation.

     The right of indemnification is in addition to any rights to which any
such person may otherwise be entitled and inures to the benefit of the
executors or administrators of each such person.  The Registrant may pay
the expenses incurred by any such person in defending a civil or criminal
action, suit or proceeding in advance of the final disposition of such
action, suit or proceeding, upon receipt of an undertaking by such person
to repay such payment if it is determined that such person is not entitled
to indemnification hereunder.  This section is subject to amendment or
repeal only by action of the stockholders.

                                   3
The Registrant maintains on behalf of its directors and officers
insurance protection against certain liabilities arising out of the dis-
charge of their duties.  The Registrant also maintains insurance covering
the Registrant against indemnification payments to its directors and
officers for certain liabilities.  However, to the extent such coverage is
inadequate to cover claims against directors or officers, the Registrant
may be required pursuant to the By-Laws to reimburse the directors or
officers for the uninsured portion of such claims.  In such an event, the
Registrant's indemnification obligations to its directors and officers 
could have a material negative impact on the Registrant's financial condition
and on stockholder equity.

     Item 7.  Exemption from Registration Claimed.
              -----------------------------------
          Not applicable.

     Item 8.  Exhibits.
              --------
          The Exhibit Index immediately preceding the exhibits is
          incorporated herein by reference.

     Item 9.  Undertakings.
              ------------
          1.  The Registrant hereby undertakes:

          (a)   To file, during any period in which offers or sales are
     being made, a post-effective amendment to this registration statement:

          (i)   To include any prospectus required by Section 10(a)(3) of
     the Securities Act;

          (ii)  To reflect in the prospectus any facts or events arising
     after the effective date of the registration statement (or the most
     recent post-effective amendment thereof) which, individually or in
     the aggregate, represent a fundamental change in the information set
     forth in the registration statement.  Notwithstanding the foregoing,
     any increase or decrease in volume of securities offered (if the
     total dollar value of securities offered would not exceed that which
     was registered) and any deviation from the low or high end of the
     estimated maximum offering range may be reflected in the form of
     prospectus filed with the Commission pursuant to Rule 424(b) if, in
     the aggregate, the changes in volume and price represent no more than
     a 20% change in the maximum aggregate offering price set forth in the
     "Calculation of Registration Fee" table in the effective registration
     statement; and
     
          (iii) To include any material information with respect to the
     plan of distribution not previously disclosed in the registration
     statement or any material change to such information in the
     registration statement;

     provided, however that paragraphs (i) and (ii) do not apply if the
     registration statement is on Form S-3 or Form S-8, and the informa-
     tion required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed by the Registrant
     pursuant to Section 13 or Section 15(d) of the Exchange Act that are
     incorporated by reference in the registration statement.

          (b)   That, for the purpose of determining any liability under 
     the Securities Act, each such post-effective amendment shall be
     deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time
     shall be deemed to be the initial bona fide offering thereof.

                                   4
(c)   To remove from registration by means of a post-effective
     amendment any of the securities being registered which remain unsold
     at the termination of the offering.

     2.   The Registrant hereby undertakes that, for purposes of determining
any liability under the Securities Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act
(and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated
by reference in the registration statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be in the
initial bona fide offering thereof.

     3.   Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or other-
wise, the Registrant has been advised that in the opinion of the Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question
whether such indemnification by it is against public policy as expressed in
the Securities Act and will be governed by the final adjudication  of such
issue.
